We listen to a lot of music in a whole year.
For the past few years, I've been compiling YouTube playlists of some of the songs I listen to throughout each year. Looking through the many months and various genres, it's interesting to look back and chart your annual journey, your progression, your ups and downs.
I realize 2018, for me, has been a year of finally moving forward, getting rid of expectations and carving your own path, realizing that your wellbeing must come first if you're to do anything else... and so, in no particular order are six of the defining songs I listened to this year.
The world is an amazing place… and also currently terrifying, so much so that it's all we seem to think about. Dazed, confused and downtrodden like most of us are at this moment in time, this song filled my soul when I realized Young and Sick finally said something I had been meaning to: "I feel everything / And it's all too much / And I feel everything / And it's all bad news." Finally, I thought; Something in words to match my (…our?) internal madness.
It's really easy to think you know how your life will play out. The moment you let go of those expectations and become something truly different is terrifying, but this year, I learned to enjoy the thrill. Leave It's surreal production by Trevor Horn (and equally curious music video) is a sonic wonderland in which to explore a new blank slate and a whole world of possibilities.
I'll be honest. I shelved an album this year and it still hurts. I'm not sure if I'm proud of it, but there had to come a time where I had to let go, especially when I realized I wanted to tell a story about a time in my life I couldn't anymore, despite feeling I owed something to those years. Here at the crossroads was a memory that brought me back to the heart of it all and made me miss it even more. The cherry on top was being introduced to this song by my high school's acapella group. Don't we all long for those days again?
The moment this Ariana Grande cover's beautifully warm chords (arranged by Pentatonix's Scott Hoying and arranger Ben Bram) filled my ears, I knew I was in for something good, possibly life-changing. After a year of fighting my own career expectations and letting go of a lot of things, I was finally tired of being tired of it all… and here was the door into something new. Citizen Queen's lineup transformed Ariana's already liberating pop groove into something stellar and soulful, a perfect reminder to remember your own worth and move forward only when you say it's right. You call your own shots.
Thomas Dolby's The Flat Earth is without a doubt my all-time favorite song, something so transformative and introspective that it made this year's playlist twice. Yes, you read that right. I've looked up to Thomas Dolby as a musician since fifth grade, and I would definitely cite him as one of my most prominent influences… little did I know that I would have the chance to meet him in August. "You're the reason I'm a songwriter." were the first words I ever spoke to the man himself, echoing inside my head for what seemed like an eternity. And there it was. After a lifetime of music, I realized I could finally give back to it for all it's done to shape me and allow me to have purpose.
As long as we continue to aspire to give as much of ourselves as we can, we'll be in good hands. After all, the world can be any shape you want it, so why not believe that we can change it for the better?
Happy new year. Here's to a 2019 full of incredible music, old and new.
What songs made your 2018 playlist? I'd love to know.

FUNDING FOR ENERGY CONSERVATION PROGRAMS
Save on Energy - Home Assistance Program
Out-of-date household items and appliances can make electricity bills more expensive for your home or social housing property. The Save on Energy Home Assistance Program offers free energy-efficiency upgrades for income-eligible homeowners and tenants, and eligible social housing providers, as well as an in-home energy assessment to help uncover more ways to save.
Click here for more information and how to apply for the Save on Energy Home Assistance Program.
Ontario Electricity Support Program (OESP)
The Ontario Electricity Support Program (OESP) is a monthly, on-bill credit ranging from $45 to $113 per month. The program is available to all low-income customers in the province. If you're a customer of an electricity utility and have a total household income that falls below a certain limit, you may qualify for a reduction on your electricity bill through the OESP. It's also available to people living in homes that have sub-meters (apartments, condos, co-ops and trailers, for example) where each unit has an individual meter and the resident's electricity bill comes from a company other than their utility.
Click here for more information and how to apply for the Ontario Electricity Support Program.
Low-Income Energy Assistance Program (LEAP)
If you're behind on your electricity or natural gas bill and face having your service disconnected, you may qualify for emergency financial help through the Low-income Energy Assistance Program (LEAP). LEAP pays up to $500 of the amount owing on the bill ($600 if the home is heated electrically). This is a one-time (per year) emergency payment only. There are also special customer service rules available for low-income households. You need to meet certain criteria to qualify for these programs, and must go through one of the intake agencies in Ontario.
Click here for more information and how to apply for the Low-Income Energy Assistance Program (LEAP).
AffordAbility Fund
Do you pay an electricity bill in Ontario? If so, you qualify! The AffordAbility Fund is here to help Ontarians who pay an electricity bill ease what they spend on electricity. Take a few minutes to enrol and find out what you qualify for, from FREE ENERGY STAR® light bulbs, a power bar and/or faucet aerators to ENERGY STAR® appliances and home energy plans and upgrades.
Click here for more information and how to apply for the AffordAbility Fund.
Use your dishwasher and dryer early in the morning, in the evening or on weekends when electricity rates are lower.
Only run full loads in the dishwasher.
Use an outdoor clothesline during summer to save electricity.
When buying a new washing machine, look for an ENERGY STAR qualified front-load model to reduce water use by almost 45% and energy use by about 65%.
Do laundry only when you have a full load.
Refrigerators are one of the biggest electricity users in the home, so it pays to consider an ENERGY STAR qualified model.
The ENERGY STAR symbol on a new fridge means:
It is at least 15% more energy-efficient than the minimum standards set federally.
Uses half as much electricity as a fridge that's 10 years old.
Cooling and Heating Your Home
In the summer, set your central air conditioner (CAC) for 25°C when you are home, and 28°C when away. Or, if you can, turn it off.
Service your central air system annually.
Clean or replace the furnace filter once a month to keep it operating efficiently. A clogged filter impedes furnace performance.
Have a licensed HVAC (heating, ventilation, air conditioning) professional service your furnace yearly to ensure it is operating at maximum efficiency.
Electronic devices left plugged in, even when turned off, still draw power. It's called phantom power or standby power, and it's costing you money. Plug electronics into a power bar with a timer or auto shut-off and make sure they are off during periods of inactivity.
By reducing this unnecessary power use, you could help save up to 20% on your electricity use.
Check for gaps. Weather-strip around doors, fireplace dampers, attic hatches and air conditioners. Reducing drafts, can save up to 30% a year on heating costs.
Choose energy-efficient Light Emitting Diodes (LEDs) when you need to replace light bulbs.

great post ! I can't wait to see what your working on!
Thanks Kevin, you'll be hearing about it shortly – stay tuned!
I can so relate Hans! Most of us were sold a bill of goods about what the American Dream is supposed to look like then we find ourselves trapped. Breaking free and showing others how to do the same is Priceless. Great post!
It was a trap, I'll perhaps create another blog post about why we were sold the old American Dream (and who's dream it really was for us all to fall into the trap…) but in knowing there is a way out, a way we can still achieve the real American Dream of freedom is empowering and exciting. More on that to come soon!
Hey Hans a great post and I agree that the American Dream should die, the old that is also. You did a great job of stating some nice facts that one can relate to, with sharing your experience with your own home and the cost associated with it. but you also touch on a different and better way and hate the video that is coming soon, where I clicked it just to see if it was real or not that was great looking forward to seeing that video.
Hey Dan, lol. That wasn't actually my intention, you can credit YouTube for that one. Guess YouTube wanted to add some suspense and keep you from seeing that video. It is a short intro to what is coming. You can find it on my YouTube channel if you like at http://youtube.com/hanstheschoff – thanks!
This is an interesting concept — eager to hear more about it. Many years ago — probably before you were born — in the 70s, there was a movement to live off the grid. Of course it didn't spread very far because of our value on consumerism. Will go to your youtube channel to see the video.
Hey Carol, glad to hear from you. The Off-grid is movement is picking up again as well; These Tiny House on Wheels setups can make it very doable to go off-grid and require no 3rd party electric, plumbing or sewage services. Another great way to save some money and be even more free!

The What: Clear-Com's FreeSpeak II 1.9GHz has already proven to be an exceptional wireless intercom system for large scale productions. The system includes a newly designed wireless beltpack and active antenna, which delivers a more expansive cellular wireless coverage as well as more reliable connection than its predecessor, known as CellCom in North America and FreeSpeak in the rest of the world. FreeSpeak II operates in multiple world-wide license-free bands from 1.897-1.933 GHz.
The What Else: In addition to the 1.9GHz, FreeSpeak II can also now operate in the 2.4GHz frequency band with new system components. Even though FreeSpeak II 2.4GHz will have a separate yet similar set of system components as the 1.9GHz version--namely a base station, wireless beltpack, active antenna, splitter, and battery charger--the same base station or integrated FreeSpeak II systems can co-operate a mix of 1.9GHz and 2.4GHz beltpacks and antennas thus increasing both the quantity of wireless users and cell roaming area.

Q: C# Xamarin Android Multi Dex app with a custom application class that runs on pre-Lollipop I came across 65K limit and enabled Multidex, after that my was not instalkling on pre-Lollipop devices. As a result of hours of debugging and searching I found a solution here.
I changed the subclass of  Application according to accepted answer, everything was working fine till now.
I recently found out that i had given some code handling in the class as a work around whenever the app runs into an unhandled exceptions. So when i am debugging , I see that it never enters the Oncreate() and my workaround has no effect on my App.
After some research i came across the android.support.multidex.MultiDexApplication class in Java that may solve my problem. But i can't find anything like this in my SDK manager now I am able to install it in any other way.
Does Xamarin even support this feature ?
Is there anyother way to solve this? or am i in the correct direction ?

A: The solution you refer to is out of date. Now you do not need to create a custom MultiDexApplication class to make multidex work in Xamarin.
Also, android.support.multidex.MultiDexApplication is not available in Xamarin. The following is steps to enable multidex in your project.

*

*In Android Project Properties, check Enable Multi-Dex

*Create a custom multidex.keep file in your Android project and set the build action as MultiDexMainDexList

*There is a bug from Xamarin on the auto generated multidex.keep file (Link). So you will need to add in some .class file in your newly created multidex.keep file.
mono/MonoPackageManager.class
mono/MonoRuntimeProvider.class
mono/MonoPackageManager_Resources.class
mono/android/app/NotifyTimeZoneChanges.class
mono/android/app/ApplicationRegistration.class

*Add in additional class that is needed in your application into the multidex.keep file.

*You might need to perform the following:
- Clean project
- Close Visual Studio
- Delete all bin and obj folder
- Open back your solution
- Clean and build again

The '90s & 2000s Shows That Guided Me Through Teenagehood
Cue the pop culture moments and nostalgia.
by Emily Rosati
Publishing date: Aug, 12, 2021
There's something undeniably comforting about revisiting a familiar era in television that can act as a ritual of replenishment. And if you're anything like me your adult self is an amalgamation of your most beloved characters that guided you through teenagehood on the path to self-awareness. The late 90s and early 2000s were a wellspring of quintessential pop culture moments that would be criminal to be forgotten. Looking back it's funny to think that these sitcoms held such power over me that I would actually carve out time in my week for new episodes until the complete DVD box set came out. If this speaks to you, buckle up for a feel-good nostalgia trip. Because you know what's better than watching a show in your youth for the first time? Binge-watching it for the second time with decades of life experience under your belt.
'Sister, Sister' (1994 – 1999)
Sister, Sister walked so that Parent Trap (1998) could run. This 90s sitcom—that ran for a total of six seasons—followed two twin sisters, Tia and Tamera Campbell, separated at birth who reunited by fluke after living very different lives. Though they look identical, the sisters embark on a journey of navigating their differences and making up for years of lost time. Sister, Sister is a wholesome comedy that hits differently as an adult and will forever leave you wondering where your long-lost twin is. If you're an only child and this doesn't resonate with you, watch it for the iconic quotes, 90s soundtrack, and guest appearances from Rupaul, 702, Kobe Bryant, and many more.
'Moesha' (1996 – 2001)
If you were an avid watcher of Moesha, then I guarantee you still find 'Mo to the E to the' looping in your brain during idle moments like commuting to work or showering. This is your subconscious reminding you to revisit Brandy's 90s sitcom. The show follows Moesha Mitchell, a young woman living with her brother Myles, their father Frank, and his new wife Dee. The show bravely confronted topics such as drug use, premarital sex, and infidelity making it one of the realest coming-of-age storylines. Another show with epic guest appearances from big names such as Bernie Mac, Big Pun, and DMX. With the recent addition of Moesha to Netflix, it leaves us wondering if we can be expecting a reboot anytime soon. Fingers crossed.
'Felicity' (1998-2002)
If you haven't already seen Felicity, you likely recognize it from hair-related references in shows like 30 Rock, Gilmore Girls, and Family Guy. The show debuted in 1998 as a part of Warner Bros' conscious teen soap lineup and ran for 4 seasons until 2002. The story followed Felicity, a recent high school graduate who decided to move to New York City—a decision that was inspired by her long-term crush. By its sophomore season, Felicity had a tonal shift that reflected the ugly and completely realistic truths of being in your college years, which makes me feel so deeply understood to this day. In the 2000s, being directionless and cutting your hair didn't make for good television and the show's ratings declined until it was canceled. I argue that this show would have held its own if it were released a decade later, which is all the more reason to go binge-watch it now. Felicity has preserved its charm and overwhelms you with a deep sense of nostalgia.
'Charmed' (1998-2006)
This one is for everyone still waiting for the awakening of their undiscovered magical powers. This enchanting occult sitcom follows sisters who discover their witch capabilities and need to combine their powers to fight off evil forces. They must rise up to their destiny as The Charmed Ones or the world as they know it may cease to exist, no big deal. Whether it is the tender feel-good family moments, the heavy Star Wars visual influence, or its depiction of postmodern femininity, Charmed will have you under its spell and forever categorizing the people in your life as a Prue, Piper, or Phoebe. If you've binge-watched all 8 seasons and are left wanting more, you can dive into the Charmed reboot that has an adjacent plot with more progressive subject matter.
'Girlfriends' (2000-2008)
A post shared by Tracee Ellis Ross (@traceeellisross)
We can all agree that 2020 was a tough year, but it had one redeemable moment; Girlfriends being added to the Netflix catalog. Not many people have the power to boost serotonin like Tracee Ellis Ross. The show follows four best friends Joan, Toni, Maya, and Lynn as they maneuver through the perils of adulting in a much better wardrobe than mine will ever be. Girlfriends has range! It addresses topics like friendships, dating, interracial relationships, and HIV awareness. There are 8 seasons of reasons to watch this show, the biggest being that it is continuously teaching you how to be a better, more supportive friend. Once you've binged your way through, you can look forward to The Game, a spinoff following Girlfriends character Melanie Barnett. Until then, you have 172 chances to get the theme tune harmony down.
'The Bernie Mac Show' (2001-2006)
Leave it to Bernie Mac to stay true to his humor even with the constraints of broadcast television. The Bernie Mac Show ran on FOX between 2001 and 2006 for a total of 5 strong seasons. The series features Bernie and his wife Wanda who are forced to navigate parenthood after Bernie's sister drops her three children Bryanna, Jordan, and Vanessa off at their door on her way to rehab. The show's journey began with a single skit on The Original Kings of Comedy which FOX then turned into a weekly sitcom. If you enjoy sitcoms and movies that frequently break the fourth wall, this is for you. Bernie Mac plays himself, which allowed other notable celebrities like Chris Rock, Ice Cube, and Flavor Flav to play themselves on the show as a plot device. Bernie Mac has left behind an untouchable comedy legacy that deserves to be indulged.
'8 Simple Rules' (2002-2005)
8 Simple Rules is everything I wished Home Improvement would have been and redeemed the daddio sitcoms, sorry not sorry! Simply put, this show is an overlooked masterpiece in the wholesome-family-sitcom genre. 8 Simple Rules starred Katey Sagal and John Ritter as Paul and Cate Hennessy, raising their three teenagers Bridget, Kerry, and Rory. The show's premise was based on the book 8 Simple Rules for Dating My Teenage Daughter by W. Bruce Cameron, which highlights a pretty solid foundation for dating standards. The show's trajectory took an unexpected turn when John Ritter tragically passed away in 2003. Though it was no easy feat, the show managed to pilot the direction with grace and vulnerability. The series acts as a heart-warming reminder that family can truly be a source of strength through difficult times. John Ritter will remain forever in my heart as one of the best tv dads in history.
'The O.C.' (2003-2007)
Look, I'm just going to say it: The O.C. was a cultural reset. Gen Z may never understand what this moment in time meant to Millennials. Not only was the plot fascinating and characters promising—the basic components of any good show—The O.C.'s influence was further-reaching than anyone could have predicted. The O.C. follows Ryan Atwood, a bright young man from a broken home, adopted by an upper-class family from Newport Beach. Ryan and his socially awkward but loveable stepbrother Seth Cohen, spend most of their time crushing hard on Marissa Cooper and Summer Roberts. So, why did The O.C. have such a cultural impact? Nerd culture reigned supreme, indie bands went mainstream, and a new breed of reality TV emerged; the markers of a coming-of-age phenomenon. Not to mention the soundtrack was always amazing. Gen Z can come for skinny jeans and sidebangs on TikTok but they can't challenge The O.C.'s lasting legacy as it will forever be a sentimental part of the 2000s identity.

When you think about it, all essays are persuasive really. We wouldn't sit down and actually put our hearts and souls into writing an essay if we weren't trying to get someone to agree with us, right?
Well, persuasive essays are ones in which we very obviously—very directly try to persuade our reader to care about our topic and to do something about it.
What is the purpose of a persuasive essay?
For all of these topics below—if it is in question form, such as, "should students be required to wear uniforms—you need to choose one side of the argument, they should or they shouldn't and argue that side from the beginning.
I believe that requiring the wearing of school uniforms, especially in older students, helps to level the playing field and help students focus on their studies—not what they will wear the next day.
Then you persuade them you're right with solid evidence.
Students should not be allowed to have cellphones in class, at all. (you have to get your reader to agree with this point of view or you could argue it's opposite!
***I won't say this for all topics—but you can take any topic here and flip it to the opposite side.
Should students be required to wear uniforms? Persuade your reader toward one point of view or another. You'll have to chose a side.
People should have to wait until the age of 18 (or 19, or 20) to begin driving to reduce texting and driving fatalities. We must do something strong to make a statement about this before there are any more fatalities due to texting.
Legalization of marijuana would stimulate the economy. We might as well legalize this drug and let it stimulate our recessed economy.
Should we change the laws in all states to allow people to shoot those who break into their house?
We need to take action now to reduce childhood obesity in America.
Should gay marriage be legalized throughout the United States?
Should downloading free music and movies on sites like Pirate Bay be made illegal?
Should teachers be tested more often on their skills as educators?
Should we raise the buying age on violent video games to help prevent school shootings and other disasters?


And now, if you want to know the story of TommyBoy machine, let's start from the beginnig.
This challenge has a story, and quite an enjoyable one IMHO and this will make things more interesting and pleasant.
HOLY SCHNIKES! Tommy Boy needs your help! The Callahan Auto company has finally entered the world of modern technology and stood up a Web server for their customers to use for ordering brake pads. Unfortunately, the site just went down and the only person with admin credentials is Tom Callahan Sr. - who just passed away! And to make matters worse, the only other guy with knowledge of the server just quit! You'll need to help Tom Jr., Richard and Michelle get the Web page restored again. Otherwise Callahan Auto will most certainly go out of business :-( Objective ================= The primary objective is to restore a backup copy of the homepage to Callahan Auto's server. However, to consider the box fully pwned, you'll need to collect 5 flags strewn about the system, and use the data inside them to unlock one final message.
On the source page there are a few messages (but very useful – eg. indicating that on this machine is a blog) .. I will keep all this info in my notes.
Reading the posts and comments on the blog new useful information is revealed and we have also a password protected post that must be important.
From another comment on the blog, we get information that there is a folder named /richard.
Analyzing with Exiftool the .jpg file in that directory, I discovered a comment that seems to be an MD5 hash. Putting it on hashkiller the password is instantly found: spanky. This will unlock the password protected blog post.
Coming back to the blog I was able to use the password "spanky" to see the content of the protected post.
Having the information above the FTP port is easly found on tcp 65534. After some tries we found the valid password which is the same as the username: nickburns.
Using the information from this message correlated with open ports from nmap scan, we quickly identified the folder.
Honestly, I spent some time to figure it out how to go further, and finally Steve Jobs name ringed a bell and I thought of modifying the user agent of the browser to include the iphone string.
We started our favorite web brute forcing tool – wfuzz, and identified the name of html file which is fallon1.
This will get us to the third flag.
The other hint indicates us the password pattern of the ecrypted file.
Now we have a piece of bigtommysenior SSH password and we are supposed to find the rest on a draft post in the blog. For this we need to guess the password in wordpress of user tom – discovered after a quick enumeration with wpscan. Here it was interesting… the hint indicates us that the password might be a song by Queen. Grabbed an extensive list of queens songs from wikipedia :), put them in a file and started to bruteforce – but nothing… phase one. Took the list, removed spaces, started bruteforce again, still nothing…phase two. Took the list, modified case to lower, eliminate some non alphanumerical characters, started bruteforce…but no hit… phase three. Took the list, inputed it in john to obtain permutations, started bruteforce…still nada 🙂 phase four. I seriously started to question the password has something to do with a Queen's song.
As a last resort, took 10_million_password_list_top_1000000.txt dictionary and started the "start and forget" bruteforce. After some time, when I returned to the console….incredible, we have a hit – the password is tomtom1 . It took me some time but here it is.
Armed with this information I logged on the blog and got the rest of the bigtommysenior SSH password.
All we need is to start a webshell which will run under www-data privileges and we will be able to read the file, or get root and have all the privileges.
Uploaded some files, tried some tricks to put an PHP file on the server, but the application seems to validate the uploaded files pretty well, allowing only certain media extension files. Having ssh access to the machine is an advantage, allowing me to look at the PHP code and read other files also. Looking on .htaccess file I found an interesting "backdoor" that will allow execution of .gif files as PHP.
Now, all we have to do is put together all the flags as a big, big password and decrypt the LOOT.zip file to get the last flag which is shown at the beginning of this article.

Q: how do I reincorporate a fork of my repo on github I have a small github project which has been forked by another user. I like the changes he's made. What's the best way to merge them back into my original repo?
Everything I find online deals with going the other way - updating your fork from the original repo. I want to do the opposite and pull back in changes made by another coder.
Is asking her to submit a pull-request the only way?

A: Add that repo as a new remote to your local repo, start pulling changes from the other repo on your branches and push them into your original repo.

A: The easiest way to do this is through GitHub pull requests. Note that anyone can make a pull request between a fork and an original repository as long as they can view both repositories (you don't need write access to send pull requests).

*

*Visit the fork on GitHub.

*If the branch you want to merge in isn't master, click on the branch switcher to select the branch.

*Click New pull request next to the branch switcher.

*Optionally write a title and description for future reference.

*Create and merge the pull request, which will update your original repository with the fork's changes.

The Taiwanese computer maker showed off the Aspire R7 notebook, Aspire P3 Ultrabook, and Acer Iconia A1 tablet during an event in New York.
NEW YORK--Acer on Friday launched two new touch-screen notebooks and a tablet, hoping to attract buyers and stem its steep declines in the PC market.
One notebook, the Aspire R7, features a 15.6-inch touch screen and a hinge that allows users to rotate and flip the screen to convert it in tablet. The company moved the keyboard closer to the edge of the lower tray and shifted the trackpad closer to the screen, which it said should make it easier to use the touch screen. The $1,000 product will be in stores in mid-May, with an exclusive U.S. partnership with Best Buy.
Acer also unveiled the Acer Aspire P3 ultrabook that can be converted into a tablet, as well as a 7.9-inch Acer Iconia A1 Android tablet that will retail starting in June for $169. The P3 sells for $800 and is available now.
Windows 8 meets 8-inch tablet?
"Users will have the opportunity to enjoy a totally different experience through those devices," Acer CEO JT Wang said Friday.
The Taiwanese computer maker revealed the products during a press event, with the tag line "redefining the computing experience through touch," in Milk Studios in New York's Chelsea neighborhood.
The entire PC market is slowing, but Acer has suffered even more than most of its rivals. It lost its big bet on Netbooks, which has led to steep shipment declines in recent periods. Its first-quarter global PC shipments dropped 31 percent from the previous year, according to IDC. The company has been betting on new lower-priced, touch-based Windows 8 devices to boost its results, as well as tablets running other operating systems like Android.
Wang said Friday during the event that Acer expects second-quarter sales of Windows 8 touch notebooks to double from the first quarter.

Ivana Marie "Ivanka" Trump (; born October 30, 1981) is an American businesswoman and the first daughter of Donald Trump, 45th president of the United States from 2017 to 2021. She was a senior advisor in his administration, and also was the director of the Office of Economic Initiatives and Entrepreneurship. She is the daughter of Trump's first wife, Ivana, and is the first Jewish member of an American first family, having converted before marrying her Jewish husband, Jared Kushner.

She was an executive vice president of the family-owned Trump Organization. She was also a boardroom judge on her father's TV show, The Apprentice. Starting in March 2017, Trump left the Trump Organization to become a senior adviser in her father's presidential administration alongside Jared Kushner. After ethics concerns were raised about her having access to classified material while not being held to the same restrictions as a federal employee, Trump agreed to voluntarily file "financial disclosure forms required of federal employees and be bound by the same ethics rules". While serving in the White House, she continued to operate her clothing brand business until July 2018, which also raised ethics concerns, specifically conflicts of interest. Trump was considered part of the president's inner circle even before becoming an official employee in his administration.

Early life
Trump was born on October 30, 1981, in Manhattan, New York City, as the second child and first daughter of Czech-American model and professional skier Ivana () and Donald Trump. Her father has German and Scottish ancestry. For most of her life, she has been nicknamed "Ivanka", a Slavic diminutive form of her first name Ivana. Her parents divorced in 1990 when she was 9 years old. She has two brothers, Donald Jr. and Eric, a half-sister, Tiffany, and a half-brother, Barron.

She attended Christ Church and the Chapin School in Manhattan until age 15 when she switched to Choate Rosemary Hall in Wallingford, Connecticut. When Trump was attending boarding school as a teenager, she began modeling "on weekends and holidays and absolutely not during the school year," according to her late mother, Ivana. In May 1997, she was featured on the cover of Seventeen which ran a story on "celeb moms & daughters".

After graduating from Choate in 2000, Trump attended Georgetown University for two years before transferring to the Wharton School of the University of Pennsylvania, from which she graduated cum laude with a bachelor's degree in economics in 2004. She was the first Jewish member of a first family, having converted before marrying her husband, Jared Kushner, in 2009.

Career

Business
After graduating from Wharton, her father's alma mater, Trump briefly worked for Forest City Ratner. As Executive Vice President of Development & Acquisitions of The Trump Organization, Trump was charged with the domestic and global expansion of the company's real estate interests. Along with her father and her siblings, Donald Jr. and Eric, Ivanka Trump directed all areas of the company's real estate and hotel management platforms. She participated in Trump and Trump-branded projects, including deal evaluation, pre-development planning, financing, design, construction, sales, and marketing. Her portfolio included Trump Hotels' highly acclaimed properties in New York, both on Central Park and in SoHo, Chicago, Las Vegas, Waikiki Beach, Panama, Toronto, Miami, Washington, D.C., Rio de Janeiro, and Vancouver.

In February 2012, Trump led the Request for Proposal (RFP) with the GSA, resulting in the final selection of The Trump Organization to develop the historic Old Post Office (Washington, D.C.). She then oversaw the $200-million conversion of the historic building into a luxury hotel, which opened in 2016.

The Trump Organization also acquired Doral Hotel & Spa near Miami, Florida, now known as Trump National Doral. Trump spearheaded this acquisition and oversaw the $250 million renovations of the 800-acre property.

Soon after joining the Trump Organization in an executive position, she started her jewelry, shoe, and apparel lines, and appeared in advertisements promoting the Trump Organization and her products. Trump was also featured in women's and special interest publications and was featured on the cover of some, such as Harper's Bazaar, Forbes Life, Golf Magazine, Town & Country, and Vogue.

She was featured on the cover of Stuff in August 2006 and again in September 2007.

In 2007, Trump formed a partnership with Dynamic Diamond Corp., the company of diamond vendor Moshe Lax, to create Ivanka Trump Fine Jewelry, a line of diamond and gold jewelry sold at her first flagship retail store in Manhattan. In November 2011, her flagship moved from Madison Avenue to 109 Mercer Street, a larger space in the SoHo district. Celebrities were spotted wearing her jewelry including Jennifer Lopez on the cover of Glamour and Rihanna on the cover of W Magazine. Her brand was named "Launch of the Year' in 2010 by Footwear News. Trump's brand went on to win other awards. In December 2012, members of 100 Women in Hedge Funds elected Trump to their board. Her company eventually grew to over $500 million in sales annually. Trump closed down the company and separated herself from her business affiliations at the Trump Organization after she moved to DC to serve as a senior advisor in her father's White House.

On October 2, 2015, it was reported that "Ivanka Trump's flagship store on Mercer Street appear[s] to be closed" and, noting that the shop had been "stripped clean". In October 2016, the only dedicated retail shop and flagship boutique for Ivanka Trump Fine Jewelry was located at Trump Tower in Manhattan, with her brand also being available at Hudson's Bay and fine-jewelry stores throughout the U.S. and Canada, as well as in the Gulf states.

She also had her own line of Ivanka Trump fashion items, which included clothes, handbags, shoes, and accessories, available in U.S. and Canadian department stores including Macy's and Hudson's Bay. In 2017, Aquazzura Italia SRL sued Trump, accusing her business of stealing their designs, and the suit was settled. Her brand was criticized by PETA and other animal rights activists for using rabbit fur. Ivanka Trump-brand shoes have been supplied by Chengdu Kameido Shoes in Sichuan and Hangzhou HS Fashion (via G-III Apparel Group) in Zhejiang.

In 2010, Trump's brand was named "Launch of the Year" by Footwear News.

In 2015, the Accessories Council Excellence Awards recognized Trump with the Breakthrough Award, presented by designer Carolina Herrera.

Between March and July 2016, Trump applied for 36 trademarks in China. Seven were approved between her father's inauguration in January 2017 and Chinese President Xi Jinping's state visit in the U.S. in April. Three provisional trademarks for handbags, jewelry, and spa services were granted on the day Xi dined with President Trump and his family at Mar-a-Lago. According to a trademark lawyer, the process usually takes 18 to 24 months. A Chinese government spokesman said that "the government handles all trademark applications equally."

On February 2, 2017, after months of customers boycotting and poor sales, department store chains Neiman Marcus and Nordstrom dropped Trump's fashion line, citing "poor performance." Other retailers such as Marshall's, TJ Maxx and the Hudson's Bay Company stopped selling her products. In June 2017, three people with the organization called China Labor Watch were arrested by Chinese authorities while investigating Huajian International, which makes shoes for several American brands, including Trump's brand. The Trump Administration called for their release.

On July 24, 2018, Trump announced that she shut down her company after deciding to pursue a career in public policy instead of returning to her fashion business. Before she decided to close her brand, the business had grown to over $500 million in sales annually.

Television

The Apprentice
In 2006, Trump filled in for Carolyn Kepcher on five episodes of the fifth season of her father's television program The Apprentice, first appearing to help judge the Gillette task in week 2. Like Kepcher, Trump visited the site of the tasks and spoke to the teams. Trump collaborated with season 5 winner Sean Yazbeck on his winner's project of choice, Trump SoHo Hotel-Condominium.

She replaced Kepcher as a primary boardroom judge during the sixth season of The Apprentice and its follow-up iteration, Celebrity Apprentice.

Other TV appearances
In 1997, at the age of 15, Trump co-hosted the Miss Teen USA Pageant, which was partially owned by her father, Donald Trump, from 1996 to 2005.

In 2006, Trump was a guest judge on Project Runway's third season, alongside Heidi Klum, Nina Garcia, and Vera Wang. She reappeared as a guest judge on season 4 of Project Runway All-Stars in 2014 and 2015, alongside host Alyssa Milano, judges Georgina Chapman and Isaac Mizrahi, and guest judges Betsey Johnson, Michael Bastian, Elie Tahari, Nina Garcia, and Zac Posen.

In 2010, Trump and her husband made a cameo portraying themselves in Season 4 Episode 6 of Gossip Girl.

Modeling
When Trump was attending boarding school as a teenager, she began modeling "on weekends and holidays and absolutely not during the school year," according to her late mother, Ivana Trump. She was featured in advertisements for Tommy Hilfiger, Elle, Vogue, Teen Vogue, Harper's Bazaar, and Thierry Mugler, She also engaged in fashion runway work. In May 1997, she was featured on the cover of Seventeen.

Trump has been profiled in many women's fashion magazines, including Vogue, Glamour, Marie Claire, and Elle. She was featured on covers such as Harper's Bazaar, Forbes, Forbes Life, Marie Claire, Golf Digest, Town & Country, Elle Décor, Shape, and Stuff magazine.

Trump was featured in Vanity Fairs annual International Best Dressed List in 2007 and 2008.

Books
In October 2009, Trump's first self-help book, The Trump Card: Playing to Win in Work and Life, was published; according to ghostwriter Daniel Paisner, he co-wrote the book.

In May 2017, her second self-help book, Women Who Work: Rewriting the Rules for Success, was published; as a standard practice, she used the services of a writer, a researcher, and a fact-checker. The book debuted in the number four spot in the "Advice, How-To and Misc." category of The New York Times Best Seller list. Trump donated the unpaid portion of her advance and all future royalties received from Women Who Work to the Ivanka M. Trump Charitable Fund, which makes grants that empower women and girls. She donated $200,000 in royalties to the National Urban League and the Boys and Girls Clubs of America. Trump funded a Women's Entrepreneur Center at the National Urban League in Baltimore, Maryland, after visiting the facility with Marc Morial, President of the National Urban League.

Trump campaign and administration

2016 presidential campaign and election
In 2015, Ivanka Trump introduced her father, Donald J. Trump, at Trump Tower as he announced his candidacy for president of the United States. In 2015, she publicly endorsed her father's presidential campaign. She was involved with the campaign by making public appearances to support and defend him. However, she admitted mixed feelings about his presidential ambitions, saying in October 2015, "As a citizen, I love what he's doing. As a daughter, it's obviously more complicated." In August 2015, Donald Trump stated that she was his leading advisor on "women's health and women" and said it was she who propelled him to elaborate on his views of women.

In January 2016, Trump was featured in a radio ad that aired in the early voting states of Iowa and New Hampshire, in which she praised her father. She appeared by his side following the results of early voting states in 2016, in particular briefly speaking in South Carolina. She was not able to vote in the New York primary in April 2016 because she had missed the October 2015 deadline to change her registration to Republican.

Trump introduced her father in a speech immediately before his own speech at the 2016 Republican National Convention (RNC) in July. The George Harrison song "Here Comes the Sun" was used as her entrance music. She stated, "One of my father's greatest talents is the ability to see the potential in people", and said he would "Make America Great Again." Her speech was well received as portraying Donald Trump "in a warmer-than-usual light", according to The Washington Post. After the speech, viewers commented that the speech was "one of the best – if not the best – of the night," and that Trump is the "greatest asset Donald Trump has". Others said that her speech was the "high point of the convention".

An earlier Post article had questioned whether the policy positions Ivanka Trump espoused were closer to those of Hillary Clinton than to those of her father. After the speech, the George Harrison estate complained about the use of his song as being offensive to their wishes. The next morning, Ivanka's official Twitter account tweeted, "Shop Ivanka's look from her #RNC speech" with a link to a Macy's page that featured the dress she wore.

After her father's election, Trump wore a bracelet on a family appearance with the president-elect on 60 Minutes. Her company then used an email blast to promote the bracelet. After critiques for "monetization", the company quickly apologized, calling the publicity the work of "a well-intentioned marketing employee at one of our companies who was following customary protocol." A spokeswoman said the company was, post-election, "proactively discussing new policies and procedures with all of our partners going forward."
Trump has collected the work of artists who have protested to her directly following her father's election victory. In January 2017, artist Richard Prince returned a $36,000 payment he received for a work featuring Ivanka and disavowed its creation. Other artists joined behind a movement created by the Halt Action Group called @dear_ivanka, which aimed to change Trump's policies by appealing to Ivanka. Among its supporters were contemporary artist Alex Da Corte who told Trump to stay away from his paintings after she appeared in front of one on a social media post.

On Friday, January 20, 2017, she attended the inauguration of Donald Trump as the 45th president of the United States, at the United States Capitol Building in Washington, D.C. Ivanka Trump partly negotiated rates of hotel rooms, rental spaces, and meals at the Trump International Hotel in Washington, D.C., on which her father's inaugural committee spent funds it privately raised (a standard practice for inaugural committees), WNYC and ProPublica reported in December 2018.

, the United States attorney for the District of Columbia requested some documents about her and her sibling's role in her father's inauguration, although Trump did not have "any official role in running the committee".

Advisor to the President of the United States
In January 2017, Trump resigned from her position at the Trump Organization. The organization also removed images of Trump and her father from their websites, in accordance with official advice on federal ethics rules.

After advising her father in an unofficial capacity for the first two months of his administration, Trump was appointed "First Daughter and Advisor to the President," a government employee, on March 29, 2017; She did not take any salary for the position and didn't receive any government health benefits during her four years at the White House. She also became the head of the newly established Office of Economic Initiatives and Entrepreneurship.

During the early months of her father's administration, some commentators compared her role in the administration to that of Julie Nixon Eisenhower, daughter of President Richard Nixon. Nixon's daughter was one of the most vocal defenders of his administration, and Ivanka Trump defended President Trump and his administration against a myriad of allegations. Washington Post opinion columnist Alyssa Rosenberg wrote, "Both daughters served as important validators for their fathers."

In late April 2017, Trump hired Julie Radford as her chief of staff. Before the end of the month, Trump and Radford had plans to travel with Dina Powell and Hope Hicks to the first W20 women's summit. The W20 was organized by the National Council of German Women's Organizations and the Association of German Women Entrepreneurs as one of the preparatory meetings leading up to the G20 head-of-state summit in July. At the conference, Trump spoke about women's rights. The US media reported that when she praised her father as an advocate for women, some people in the audience hissed and booed in response.

On April 24, 2017, Trump and World Bank President Jim Kim authored an op-ed published in the Financial Times on women's economic empowerment, highlighting the critical role that women play in the development of societies and the business case for involving women in the formal economy. In July 2017, Trump attended the G20 Summit in Hamburg, Germany, with President Trump and the United States delegation. She launched We-Fi (Women Entrepreneurs Finance Initiative), a United States-led billion-dollar World Bank initiative to advance women's entrepreneurship.

In August 201, President Trump announced that Ivanka would lead a U.S. delegation to India in the fall in global support of women's entrepreneurship. In response to the announcement, a low-level Indian diplomat was quoted as stating, "We regard Ivanka Trump the way we do half-wit, Saudi princes. It's in our national interest to flatter them." The majority of reactions to her actual performance alongside Indian Prime Minister Modi at the event were substantial. Anu Acharya, the founder of a medical diagnosis company, said: "What mattered to me is that she has been an entrepreneur, and she is an adviser to the president of the U.S." Shveta Raina, who runs Talerang, a startup that prepares Indian college graduates for the workplace, said Trump exceeded her expectations. "She was poised and was able to answer questions that were seemingly off-script. I think she is young and represents young women, so I think she was the right choice." Still, some in the local India-based media dubbed hers "a royal visit."

Following the annual release of the Department of State's Trafficking in Persons Report, in September 2017, Trump delivered an anti-human trafficking speech at the United Nations General Assembly, calling it "the greatest human rights issue of our time". The event was hosted by British Prime Minister Theresa May, who personally invited Trump to a patriciate, in collaboration with Great Britain and Ireland. Trump said, "This is a call for action, a call for global unity," and noted that President Trump said he is "prepared to bring the full force and weight of our government" to combat human trafficking. Prime Minister May thanked Ivanka Trump for the "personal shared commitment" to the issue.

Two days after Trump's announcement about his daughter's trip to India, the terror attack in Charlottesville occurred, and she and Jared Kushner flew off into Trump Organization helicopter for a two-day getaway in Vermont.

Biographer and journalist Michael Wolff wrote a book released in January 2018 based on numerous interviews with members of Donald Trump's circle. In it, Wolff claims—but cites no sources—that Trump and her husband reached a deal that "[i]f sometime in the future the opportunity arose, she'd be the one to run for president".

Trump led the United States presidential delegation to the 2018 PyeongChang Olympic Winter Games closing ceremony in February 2018. She said in a statement, "We are very, very excited to attend the 2018 Olympic Winter Games to cheer for Team USA and to reaffirm our strong and enduring commitment with the people of the Republic of Korea". She dined with South Korean President Moon Jae-in at his residence, the Blue House, following the closing ceremony, where she received a second invitation to South Korea in order to further ties between Seoul and Washington.

Beginning the summer of 2018, Trump and Secretary of Commerce Wilbur Ross created and led the newly-established National Council for the American Worker which worked to developed a national strategy for training and retraining the workers needed in high-demand industries. With Ross, Trump co-chaired the American Workforce Policy Advisory Board and led its members including Tim Cook, Doug McMillon, Ginni Rometty, and Marilyn Hewson.
She and her father attended the 2019 G20 Osaka summit in late June 2019; the French government released a video of her awkwardly inserting herself into a conversation with world leaders, leading to online parodies and memes.

On June 30, 2019, Trump participated in talks between her father and North Korean leader Kim Jong-un inside the Korean peninsula's demilitarized zone. She described the experience as "surreal."

Trump went in a worldwide tour in 2019 to promote her "Women's Global Development and Prosperity Initiative", in which she traveled to Ethiopia and Ivory Coast, in sub-Saharan Africa, in April; and to Argentina, Colombia and Paraguay, in South America, in September; and to Morocco, in northern Africa, in November. She also attended the 74th United Nations General Assembly to promote her initiative. In 2021, a Government Accountability Office audit concluded that Trump's initiative, which spent $265 million a year of taxpayer money on 19 women's empowerment projects, failed to target the money towards projects that related to women's empowerment, and did not measure the impact of the spending.

In June 2020, Trump was credited with proposing the controversial photo opportunity for President Donald Trump holding a bible in front of St. John's Church, which required violently clearing peaceful protesters. She walked with her father to the site and carried the bible in her Max Mara purse.

In July 2020, Trump tweeted a picture of herself with a Goya Foods bean can, endorsing the product. The owner of Goya Foods had days prior praised President Trump, leading to a backlash against the company. Trump's tweet raised ethics concerns, given that Trump is an official adviser in the White House, and employees in public office are not permitted to endorse products.

While serving in her father's administration, Trump retained ownership of businesses, which drew criticism from government ethics experts who said it created conflicts of interest. It is not possible to determine the exact amount of Trump's outside income while working in her father's administration because she is only required to report the worth of her assets and liabilities in ranges to the Office of Government Ethics. The incomes of Trump and her husband Jared Kushner ranged from $36.2 million to $157 million in 2019, at least $29 million in 2018, and at least $82 million in 2017. In 2019, she earned $3.9 million from her stake in the Trump hotel in Washington, D.C.

2020 presidential campaign

On August 27, 2020, Trump introduced her father at the 2020 Republican National Convention, by which he proceeded on the front lawn of the White House to accept the party's nomination before a crowd of supporters. Prior to that, she defended her tenure as advisor in the administration.

Capitol riot and post-presidential career
On January 6, 2021, Ivanka refused to address the rally at the Ellipse but was in attendance.

During the ensuing riot at the U.S. Capitol, she encouraged her father to make a video on Twitter condemning the riots, acting as an intermediary between besieged U.S. officials and the President. (Donald Trump's video resulted in him being banned from the platform as he said "we love you" to the rioters.) She tweeted a request for "peaceful" behavior in which she addressed the rioters as "American Patriots." Minutes later, she deleted the tweet.

In June 2022, Ivanka told the panel of the United States House Select Committee on the January 6 Attack that she does not believe the election was stolen and accepted William Barr's conclusion that voter fraud claims have "zero basis".

On November 15, 2022, asked about her father's 2024 bid for the presidency, she said: "I do not plan to be involved in politics."

Social and political causes

In 2007, Ivanka Trump donated $1,000 to the presidential campaign of then-Senator Hillary Clinton. In 2012, she endorsed Mitt Romney for president. In 2013, Trump and her husband hosted a fundraiser for Democrat Cory Booker, and the couple bundled more than $40,000 for Booker's U.S. Senate campaign.

During her father's presidency, Trump transformed from a liberal to an "unapologetically" pro-life, "proud Trump Republican." At the 2016 Republican National Convention, she said of her political views: "Like many of my fellow millennials, I do not consider myself categorically Republican or Democrat." In 2018, Trump changed her New York voter registration from Democratic to Republican.

Philanthropy
In 2010, Trump cofounded Girl Up with the United Nations Foundation. Of the program, Trump said, "Girl Up 'for girls, by girls' approach encourages American girls to become forces of global change. I am proud to be working with Girl Up and girls in this country to help ensure that all girls – no matter where they are born – get the tools they need to be educated, healthy, counted and positioned to be the next generation of leaders."

Trump was a member of the Donald J. Trump Foundation board until the foundation was dissolved after then New York attorney general Barbara Underwood filed a civil lawsuit against the foundation, alleging "persistently illegal conduct" with respect to the foundation's money. In November 2019, Trump's father was ordered to pay a $2 million settlement for misusing the foundation for his business and political purposes. The settlements also included mandatory training requirements for Ivanka Trump, Donald Trump Jr., and Eric Trump.

Trump also has ties to a number of Jewish charities, including Chai Lifeline, a charity which helps to look after children with cancer. Other charities she supports include United Hatzalah, to which her father, Donald Trump, has reportedly made six-figure donations in the past.

After she was appointed advisor to the president, Trump donated the unpaid half of the advance payments for her book Women Who Work: Rewriting the Rules for Success to the National Urban League and the Boys and Girls Clubs of America. She further said that any royalties exceeding the advances would also be given to charity.

Personal life

Ivanka Trump has a close relationship with her father, who has publicly expressed his admiration for her on several occasions. Ivanka has likewise praised her father, complimenting his leadership skills and saying he empowers other people.

According to her late mother, Ivanka speaks French and understands Czech. Sarah Ellison, writing for Vanity Fair in 2018, indicated Ivanka Trump was the family member that "everyone in the family seems to acknowledge" is her father's "favorite" child. This had been confirmed by the family members themselves in a 2015 interview with Barbara Walters on network television where the siblings were gathered and acknowledged this.

In January 2017 it was announced that she and Kushner had made arrangements to establish a family home in the Kalorama neighborhood of Washington, D.C. Federal filings implied that, in 2017, Trump and her husband may have assets upwards of $740 million. They had previously shared an apartment on Park Avenue in New York City, which Trump chose due to its proximity to her work with the Trump Organization. The residence was featured in Elle Decor in 2012 with Kelly Behun as its interior decorator. Since leaving Washington in 2021, Ivanka and her husband have been residents of Surfside, Florida.

She has an estimated net worth of $300 million.

Relationships and marriage
In college, Trump was in a nearly four-year relationship with Greg Hersch. From 2001 to 2005, she dated James "Bingo" Gubelmann.

In 2005, she started dating real estate developer Jared Kushner, whom she met through mutual friends. The couple broke up in 2008 due to the objections of Kushner's parents but got back together and married in a Jewish ceremony on October 25, 2009. They have three children: daughter Arabella Rose, born in July 2011, and sons Joseph Frederick and Theodore James born in October 2013 and March 2016 respectively. In an interview on The Dr. Oz Show, Trump revealed that she had suffered from postpartum depression after each of her pregnancies.

Religion

Raised as a Presbyterian Christian, Trump converted to Orthodox Judaism in July 2009, after studying with Elie Weinstock from the Modern Orthodox Ramaz School. Trump took the Hebrew name "Yael" (). She describes her conversion as an "amazing and beautiful journey" which her father supported "from day one", adding that he has "tremendous respect" for the Jewish faith. She attests to keeping a kosher diet and observing the Jewish Sabbath, saying in 2015: "We're pretty observant... It's been such a great life decision for me... I really find that with Judaism, it creates an amazing blueprint for family connectivity. From Friday to Saturday we don't do anything but hang out with one another. We don't make phone calls." When living in New York City, she used to send her daughter to Jewish kindergarten. She said: "It's such a blessing for me to have her come home every night and share with me the Hebrew that she's learned and sing songs for me around the holidays."

Trump and her husband made a pilgrimage to the grave of the Lubavitcher Rebbe, a popular prayer site, shortly before her father's election victory. On May 22, 2017, the couple also accompanied her father on his first official visit to Israel as president. As part of the trip to Israel, her father became the first incumbent U.S. president to visit the Western Wall. Ivanka also visited the Yad Vashem Holocaust memorial in western Jerusalem and the Church of the Holy Sepulchre in the Christian Quarter of the Old City of Jerusalem during the trip.

Awards and nominations
In 2012, the Wharton Club of New York, the official alumni association of the Wharton School of the University of Pennsylvania for the New York metropolitan area, gave Trump the Joseph Wharton Award for Young Leadership, one of their four annual awards for alumni.

In 2015, she was honored as a Young Global Leader by the World Economic Forum.

In 2016, she was presented with the Fashion Award for Excellence in Accessory Design.

\section{Introduction}
\label{intro}

A few years ago Derrida et al.$^{\cite{derr3}, \cite{derr2}}$
suggested an intriguing ``matrix approach" to the
one-dimensional Asymmetric Simple
Exclusion Process (ASEP). This approach
has later been used to treat variants of the
model$^{\cite{derr4}, \cite{hinrich1}, \cite{hone-pesch}}$,
extended to non steady states and by
Sch\"{u}tz et al.$^{\cite{schuetz1}, \cite{schuetz2}, \cite{schuetz4}}$,
used to study
fluctuations by Derrida et al.$^{\cite{derr5}}$ and the
multispecies case by (among others)
Isaev et al. $^{\cite{ipr}}$.

The main aim of this paper is to study the difficulties that arise
in potential
applications of the matrix approach to cases in which
the nearest neighbor interaction or the particle conservation
(both present in the ASEP) are violated.
Further light on the applicability
of the matrix method is shed by the integrability criterion
illustrated by Popkov
et al.$^{\cite{schuetz4}}$.

In section \ref{mps} we provide
a general recipe (using the generator of the process)
to find the algebra of the matrix formalism
associated to both the steady state and the whole
dynamics of any one-dimensional interacting system
such that at each step the configuration changes only in two adjacent sites.
A more complete description, with a
pedagogical aim will be given elsewhere$^{\cite{DI}}$.
In section \ref{beyond} we apply the recipe to some important interacting
systems such as the contact and voter models and show that
the matrix algebra obtained is not useful to treat them.

We will consider only systems in the lattice $\{1,
\ldots , N\}$, this is an intrinsic limitation of the matrix approach.
The dynamics of an interacting particle system is
usually defined by giving
the generator of the process, the general form of which
can be found for instance in Liggett's book$^{\cite{liggett2}}$.

For example, the generator $\Omega$ of
the ASEP, if particles jump one site to the right (left) with
rate $p$ ($q=1-p$) and
enter the lattice from the left (right) at rate $\alpha$
($\delta$) and leave it at rate
$\gamma$ ($\beta$),
is  defined by
$^{\cite{liggett2}}$:
\begin{multline}\label{liggen}
( \Omega f ) (\tau)  =\\ \!\sum_{x=1}^{N-1} [p\tau(x) (1\!-\tau(x+1))
\! + q\tau(x+1) (1\!-\tau(x))]
[ f( \tau^{x,x+1} ) -\! f( \tau ) ] \\
+[\alpha(1-\tau(1))+\gamma\tau(1)][f(\tau^{1})-f(\tau)] \\ +
[\delta(1-\tau(N))+\beta\tau(N)][f(\tau^{N})-f(\tau)]
\end{multline}
where $\tau=\{\tau(x)\}_{x=1}^N$ is the configuration of the
system, $\tau^{x,y}$ is the
configuration obtained from $\tau$ by exchanging the content of
the sites $x$ and $y$, and $\tau^x$ is the
configuration obtained from $\tau$ by
changing the content of the $x$-th site.

In the following formulas, $|V\rangle\rangle$ is a
vector in an (as yet)
unspecified linear space equipped with an inner product,
$D$ and $E$ linear operators on the same
space, $\langle\langle W|$ is an element of the dual space.
So $\langle\langle W|A|V\rangle\rangle$ is the inner product
generally written as $({\mathbf W}, A{\mathbf V})$.

The formula of Derrida et al. to write the probability of a given
configuration in the stationary state of the ASEP is$^{\cite{derr1}}$
\begin{equation}\label{derrstst}
P_N(\tau_1,...,\tau_N)=\frac{1}{Z_N}\langle\langle
W|\prod_{j=1}^{N}[\tau_jD+(1-\tau_j)E]|V\rangle\rangle\ ,
\end{equation}
where $D$, $E$, $|V\rangle\rangle$, $\langle\langle W|$
are matrices and vectors that satisfy
\begin{eqnarray}\label{derralg}
(\beta D - \delta E)|V\rangle\rangle  & = & |V\rangle\rangle \ ,\nonumber \\
pDE - qED   & = & D+E \ ,                   \\
\langle\langle W|(\alpha E - \gamma D) & = & \langle\langle W|\nonumber\
\end{eqnarray}
and $Z_N$ is a normalization factor.

One can check these formulas provide a sufficient condition
for the measure to be stationary by observing they
satisfy the recursion relations for the probabilities (first due
to Liggett$^{\cite{liggett3}}$) that relate the probabilities for the
system with $K$ sites to the ones for the system
with $K-1$ sites$^{\cite{derr1}}$.

\section{From the Generator to Matrix \\ Product States}
\label{mps}

Let us start by re-writing the generator by making use
of a formalism borrowed from quantum mechanics.
For all
$ j=1,...,N$ let us define the Hilbert space
${\cal H}_j :=span\left\{ \left| 0  \right\rangle _j,\left|
  1 \right\rangle _j\right\} \cong {\mathbb C}^2\ .$
Consider the operators $a^+, a^-, n, m$ defined by:
$a^+|0\rangle  =|1\rangle , a^-|0\rangle  = 0\ ,
n|0\rangle = 0\ ,
m =  \mathbb{I}-n\ ,
a^+|1\rangle =0\ ,
a^-|1\rangle =|0\rangle\ ,
n|1\rangle   =|1\rangle$,
where $\mathbb{I}$ is the identity.
Interpreting $|0\rangle$ and $|1\rangle$ as empty
site and occupied site respectively, the role of $a^+, a^-, n$
as {\em creation, annihilation, number operators} respectively
is rather obvious.
The most immediate choice of an explicit expression for
the operators and vectors above is
$|0\rangle   = \binom{0}{1}\ ,  |1\rangle   = \binom{1}{0}
a^+  = \begin{pmatrix}
0 & 1 \\
0 & 0
     \end{pmatrix},
 n  = \begin{pmatrix}
    1 & 0 \\
    0 & 0
    \end{pmatrix} ,
        a^-  = \begin{pmatrix}
      0 & 0 \\
      1 & 0
     \end{pmatrix},
   m  = \begin{pmatrix}
      0 & 0 \\
      0 & 1
    \end{pmatrix}
   $.
Now we take the tensor product
$\mathrm{H}_{N}=\bigotimes_{j=1}^{N}{\cal H}_j$ to describe
the system on all the $N$ sites.

If we consider for example the ASEP, in this
``quantum hamiltonian'' formalism$^{\cite{schuetz3}}$ the
generator is given by
\begin{align}\label{asepham}
H &=  -\sum_{k}p(a_k^-a_{k+1}^+-n_km_{k+1})+q(a_k^+a_{k+1}^--m_kn_{k+1})+\nonumber\\
&\quad\gamma(a^-_{1} - n_{1}) + \alpha(a^{+}_{1} - m_{1})
   + \beta(a^-_{N} - n_{N}) + \delta(a^{+}_{N} - m_{N})\nonumber\\
   &= h_1^\partial+\sum_{k}h_k+h_N^\partial\ ,
   \end{align}
where the superscript $\partial$ denotes a boundary term and
   $$h_1^\partial=
   \begin{pmatrix}
   \gamma  & -\alpha \\
   -\gamma  &  \alpha
   \end{pmatrix},\
   h_k=\begin{pmatrix}
   0 & 0  & 0  & 0 \\
   0 &  p & -q & 0 \\
   0 & -p & q  & 0 \\
   0 & 0  & 0  & 0
   \end{pmatrix},\ h_N^\partial=
   \begin{pmatrix}
    \beta & -\delta \\
   -\beta &  \delta
   \end{pmatrix}.$$
For any given operator or vector $b$ in the space ${\cal H}_k$
we use the notation
$b_k\equiv \mathbb I\otimes\cdots\otimes\mathbb I\otimes b
\otimes\mathbb I\cdots\otimes\mathbb I$
with $b$ as $k$-th factor.
Using a different $h_.$, this formulation can be used for any process
(like the voter and contact, e.g.) such that the occupation
number of each site is either 0 or 1, and such that the dynamics involves
a couple of neighboring sites at a time (slight generalizations
can be treated as well$^{\cite{hinrich1}\cite{hone-pesch}}$).
The generator in (\ref{asepham}) is the same as in (\ref{liggen})
as can be checked by computing the Dirichlet Form
for both and verifying that they coincide
(the same holds for processes with different $h$).
It is however easier to look closely at each
part and see what it does. For instance $a^+a^-$
represents a jump to the right and $nm$ takes into account
the complementary event (the particle stays where it is).

We now look for a stationary solution of the master equation
\begin{equation}\label{master}
   \dot{|P(t)\rangle}=H|P(t)\rangle\
\end{equation}
which describes the dynamics of the system by giving the time evolution
of the vector of probabilities of configurations, i.e.
we look for a distribution $|P_s\rangle$ such that
$H|P_s\rangle = 0$.

In order to show where the general idea can be guessed from, let us
consider again the case of the ASEP, to show$^{\cite{hinrich1}}$
that under special conditions (namely
$(\alpha+\beta+\gamma+\delta)
(\alpha\beta-\gamma\delta)/(\alpha+\delta)(\beta+\gamma)=p-q$)
the stationary state is a product state:
$|P_s\rangle=\frac{1}{Z_N}\binom{d}{e}^{\otimes N}$
 (where
 $d=(\alpha+\delta)/(\alpha\beta-\gamma\delta)$ ,
 $e=(\beta+\gamma)/(\alpha\beta-\gamma\delta)$ and
 the normalization constant is clearly
  $Z_N=(e+d)^N$).
 To prove that $H|P_s\rangle=0$, one should first check
 \begin{equation}\label{tmr}
  h_i\left[\binom{d}{e}\otimes\binom{d}{e}\right]=
\binom{d}{e}\otimes\binom{-1}{1}
 -\binom{-1}{1}\otimes\binom{d}{e}\ .\end{equation}
This makes the sum through which $H$ is defined telescopic
(recall that we are omitting the factors of the tensor product
on which the operators act trivially as the identity),
and since
$$
  h_1^\partial\binom{d}{e}=  \binom{-1}{1}\ ,\
   h_N^\partial\binom{d}{e}= -\binom{-1}{1}\ ,
$$
the cancellation of the first term with the last is assured by
the boundary terms.

In other words, $H|P_s\rangle = 0$ would be solved for instance
if we had zero for all $i$ in the r.h.s. of (\ref{tmr}); but
this is too restrictive, so we look for the first non trivial possibility:
instead of zero, we impose a ``telescopic term". This is inspired by
the dynamics, that acts with the same $h_.$ on all couple of
adjacent sites, so the generator acts twice on each site.
We will now try to make the above approach work
for non-product states by imposing a similar
telescopic property.
The idea is to move into a richer context,
substituting the numbers 1, $e$,
$d$ appearing in (\ref{tmr}) with some time-dependent
operators (non commuting
and acting on an auxiliary space of generally infinite dimension)
$S$, $E$, $D$ to be determined, aiming to get the
weights of each possible configuration
through a bracket with a couple of vectors $\langle\langle W|$
and
$|V \rangle\rangle$ to be introduced in the same space.
For instance for a system consisting of a single site we would impose
$
\langle\langle W|\binom{D}{E}|V \rangle\rangle
=\binom{\langle\langle W|D|V \rangle\rangle}
{\langle\langle W|E|V \rangle\rangle}
= \binom{d}{e}
$
  and clearly, in the case of a product measure,
$
   \langle\langle W|\binom{D}{E}^{\otimes N}|V \rangle\rangle =
 \binom{d}{e}^{\otimes N}
$.
We can also write
$
  H \langle\langle W|\binom{D}{E}^{\otimes N}|V \rangle\rangle =
   \langle\langle W|H \binom{D}{E}^{\otimes N}|V \rangle\rangle
$.

Let us now write
 $
   |P \rangle=\frac{1}{Z_N} \langle\langle
   W|\binom{D}{E}^{\otimes N}|V \rangle\rangle
$ for the probability vector
 and plug it into the master equation (\ref{master}).
 Clearly $Z_N=\langle\langle
 W|C^N|V \rangle\rangle$, with $C=D+E$, that does not
 depends on time by conservation of probability.

It is easy to show that the master equation (\ref{master}) is satisfied
if the following equalities hold
(thanks to the same telescopic cancellation mechanism we used for
the product state)
  \begin{align}\label{algebra}
   & \left(\frac{1}{2}\frac{d}{dt}_.+h_.\right)
   \binom{D}{E}\otimes\binom{D}{E} =\nonumber \\
   & \quad \binom{D}{E}\otimes\binom{-S}{S}-
      \binom{-S}{S}\otimes \binom{D}{E} \ ,  \\
  & \langle\langle W|\left[(\frac{1}{2}\frac{d}{dt}+h_1^\partial)
   \binom{D}{E}-\binom{-S}{S}\right]=0\ ,\nonumber\\
   & \left[(\frac{1}{2}\frac{d}{dt}+h_L^\partial)
   \binom{D}{E}+\binom{-S}{S}\right] |V\rangle\rangle =0\nonumber\ .
   \end{align}
These are the relations of the matrix algebra of the process.
If we chose for example the $h_.$ of the ASEP, these equations take the
explicit form of the algebra found by Stinchcombe
and Sch\"{u}tz$^{\cite{schuetz1}, \cite{schuetz2}}$
that includes as a special
case the stationary one (\ref{derralg}) of Derrida et al.
(taking $S=\mathbb{I}$ and putting all the time derivatives equal to zero).
With this procedure we can exhibit an algebra
for all the models with a dynamics involving
only a couple of neighboring sites at a time$^{\cite{schuetz3}, \cite{schuetz7}}$
(see the same works  for a classification of the models
with different $h_.$).
If one found an explicit expression for all the operators and vectors, the model
could in principle be solved exactly (provided the algebra is not empty).
Unfortunately, this is in general very difficult
to accomplish (a purely algebraic treatment can also
be used$^{\cite{schuetz4}}$).
In the case of the ASEP, thanks to the preservation
of the number of particles in the bulk
dynamics, the local generator $h_.$ has a block form,
with zero entries in the first and last row and column.
This special form of $h_.$ is such that
in stationary conditions the four equations
(\ref{algebra}) collapse to just one: (\ref{derralg}).
But this great simplification may not occur for
different models.
In many cases the algebra
can be empty (or too complicated to deal with),
as we are going to show
for the contact and voter models.
We can say that the method works for the processes,
such as the ASEP, the probability measures of which are either
product, or a generalization that we can classify as
``matrix product measures".  If one distinguished only
between product and non-product states, the choice would be
in general only
between a numerical tensor product and a convex combination
of  as many such products as the cardinality of the configuration
space. If the states of a process are matrix product, one can chose
to deal again with a single tensor product, thanks to the richer
nature of the entries, matrices instead of numbers.

Algebras defined by conditions like (\ref{algebra}) are called
\emph{Diffusion Algebras} $^{\cite{ipr}}$.

 \section{The matrix Approach Beyond \\ Simple Exclusion}
\label{beyond}

 \subsection{Exclusion process with double jumps}

The method to write the matrix algebra of the process
can also be extended to the
case of dynamics not limited
to neighboring sites, such as for instance
the exclusion process with jumps
of length two permitted. The generator, in the case of
symmetric dynamics, is (up to boundary terms):
\begin{align*}\begin{split}
   H = &
   -\sum_{k}(a_k^-a_{k+1}^+-n_km_{k+1})+(a_k^+a_{k+1}^--m_kn_{k+1})+\\
   & (a_k^-a_{k+2}^+-n_km_{k+2})+(a_k^+a_{k+2}^--m_kn_{k+2})=\sum_{k}h_k,
   \end{split}\end{align*}
$$
h_.=\begin{pmatrix}
     0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\
     0 & 1 & 0 & 0 & -1 & 0 & 0 & 0\\
     0 & 0 & 1 & 0 & -1 & 0 & 0 & 0\\
     0 & 0 & 0 &  2 & 0 & -1 & -1 & 0\\
     0 & -1 & -1 &  0 & 2 & 0 & 0 & 0\\
     0 & 0 & 0 &  -1 & 0 & 1 & 0 & 0\\
     0 & 0 & 0 &  -1 & 0 & 0 & 1 & 0\\
     0 & 0 & 0 & 0 & 0 & 0 & 0 & 0\
   \end{pmatrix}
$$
For this system we impose the telescopic property to solve
the master equation in the following way:
\begin{align*}
&\left(\frac{1}{3}\frac{d}{dt}_.+h_.\right)\binom{D}{E}\otimes\binom{D}{E}\otimes\binom{D}{E}=
\binom{D}{E}\otimes\binom{-S}{S}\otimes\binom{D}{E}-\\
 &\qquad    2\binom{-S}{S}\otimes \binom{D}{E}\otimes\binom{D}{E}+
\binom{D}{E}\otimes\binom{D}{E}\otimes\binom{-S}{S}
\end{align*}
which is the same as
\begin{equation*}
\frac{1}{3}(2\dot{D}D^2+D\dot{D}D+D^2\dot{D})+ 0
= -DSD+2SD^2-D^2S
\end{equation*}
\begin{equation*}
\frac{1}{3}(2\dot{D}DE+D\dot{D}E+D^2\dot{E})+ D^2E-ED^2
= -DSE+2SDE+D^2S
\end{equation*}
\begin{equation*}
\begin{split}
\frac{1}{3}(2\dot{D}ED+D\dot{E}D+DE\dot{D})+ DED-ED^2
=\\ DSD+2SED-DES
   \end{split}
\end{equation*}
\begin{equation*}
\begin{split}
\frac{1}{3}(2\dot{D}E^2+D\dot{E}E+DE\dot{E})+
2DE^2-EDE-E^2D  = \\ DSE+2SE^2+DES
   \end{split}
\end{equation*}
\begin{equation*}
\begin{split}
\frac{1}{3}(2\dot{E}D^2+E\dot{D}D+ED\dot{D})
-D^2E-DED+2ED^2 =\\ -ESD-2SD^2-EDS
   \end{split}
\end{equation*}
\begin{equation*}
\begin{split}
\frac{1}{3}(2\dot{E}DE+E\dot{D}E+ED\dot{E})-DE^2-EDE
=\\ -ESE-2SDE+EDS
   \end{split}
\end{equation*}
\begin{equation*}
\frac{1}{3}(2\dot{E}ED+E\dot{E}D+E^2\dot{D})-DE^2+E^2D
=ESD-2SED-E^2S
\end{equation*}
\begin{equation*}
\frac{1}{3}(2\dot{E}E^2+E\dot{E}E+E^2\dot{E})- 0  =ESE-2SE^2+E^2S
\end{equation*}
These relations define now a cubic algebra, as opposed to a quadratic one,
which is therefore not a Diffusion Algebra in the sense of $^{\cite{ipr}}$.
Unfortunately algebras of degree higher than two are very difficult
to handle (see e.g. Vershik$^{\cite{vershik}}$).
However algebras of degree higher than two appear e.g. in
$^{\cite{schuetz4}}$.

\subsection{Voter and Contact Models}

For a description of the voter and contact models
see Liggett$^{\cite{liggett2}}$.
It is easy to see that the local
generator for the voter model can be written
in the form of the r.h.s. of (\ref{asepham})
with
   $$
  h_.=\begin{pmatrix}
     0 & -1 & -1 & 0 \\
     0 & 2  &  0  & 0 \\
     0 & 0  &  2  & 0 \\
     0 & -1 & -1 & 0 \
   \end{pmatrix}
  $$
   and
$$
h_1=\begin{pmatrix}
     0 & -\lambda \\
     0 & \lambda \
   \end{pmatrix}\ ,\ h_N=\begin{pmatrix}
     \mu & 0 \\
     -\mu & 0 \
   \end{pmatrix}
$$
where $\lambda$ and $\mu$ are the rates for opinion changing in
the boundary sites. Notice that there are non zero entries in the
first and last row.
It is easy to compute that
   $$
   h_.\binom{D}{E}\otimes\binom{D}{E}=\left(\begin{array}{c}
     -\{D,E\} \\
     2DE \\
     2ED \\
     -\{D,E\} \
   \end{array}\right)
   $$
   and so we can conclude that the algebra and its stationary limit
   are given by
   \begin{align*}
   \frac{1}{2}(\dot{D}D+D\dot{D})-\{ D,E \}
   &= [S,D] \longrightarrow \{D,E\}=0 \\
   \frac{1}{2}(\dot{D}E+D\dot{E})+2DE &= SE+DS \longrightarrow
   2DE=C \\
   \frac{1}{2}(\dot{E}D+E\dot{D})+2ED &= -(SD+ES) \longrightarrow
   2ED=-C \\
  \frac{1}{2}(\dot{E}E+E\dot{E})-\{D,E\}
   &= [E,S]\longrightarrow \{D,E\}=0
   \end{align*}
Hence in stationary conditions $$[D,E]=C\equiv D+E ,\{D,E\} = 0 ,
  \mu D|V\rangle=|V\rangle  , \langle W|\lambda E
   =\langle W|.
$$
Notice that the relations are similar to the ones of the ASEP, but
there is an additional condition: $D$ and $E$ anticommute.

The local generator of the contact model is
   $$
   h_.=\begin{pmatrix}
    0 & -\alpha & -\alpha & 0 \\
     0 & \alpha+\beta & 0 & -\alpha \\
     0 & 0 & \alpha+\beta & -\alpha \\
    0 & -\beta & -\beta & 2\alpha \
   \end{pmatrix}
   $$
   so that
   $$
   h\binom{D}{E}\otimes\binom{D}{E}=\left(\begin{array}{c}
     -\alpha\{D,E\} \\
     (\alpha+\beta)DE-\alpha E^2 \\
     (\alpha+\beta)ED-\alpha E^2 \\
     -\beta\{D,E\}+2\alpha E^2 \
   \end{array}\right)
   $$
   and so we can conclude that the algebra
   is given by
   \begin{align*}
   \frac{1}{2}(\dot{D}D+D\dot{D})-\alpha\{D,E\}
   &= [S,D] \\
   \frac{1}{2}(\dot{D}E+D\dot{E})+(\alpha+\beta)DE-\alpha E^2
   &= SE+DS \\
   \frac{1}{2}(\dot{E}D+E\dot{D})+(\alpha+\beta)ED-\alpha E^2
   &= -(SD+ES) \\
   \frac{1}{2}(\dot{E}E+E\dot{E})-\beta\{D,E\}+2\alpha E^2
   &= [E,S]
   \end{align*}
   so that in stationary conditions $E^2=0,\ [D,E]=C\  , \{D,E\} = 0$
   if we assume $\alpha=\beta=1$.

Clearly these relations define a subalgebra
of the one for the voter model.

\begin{theorem}
In stationary conditions, the algebra of the voter model is empty
(and {\em a fortiori} so is the one of the contact process and so
are the ones for the whole time evolution).
\end{theorem}
{\bf Proof }
 The algebra is
   $$
    DE=(D+E)/2\ ,\ ED=-(D+E)/2\ , $$
    $$
    DE=-ED\ ,\
    D|V\rangle=\mu|V\rangle\ ,\
    \langle W|E=\langle W|\lambda\ .
   $$
   If
   $$
    \vartheta_.=D,\ E$$ we get, from the first two conditions
   $$ \langle W|\prod_{k=1}^N\vartheta_k|V\rangle=
    \langle W|[P(D)+Q(E)]|V\rangle=
    [P(1/\mu)+Q(1/\lambda)]\langle W|V\rangle
   $$
with some polynomials $P$ and $Q$; but the third condition
(anticommutation) also implies
   $$
    \langle W|\prod_{k=1}^N\vartheta_k|V\rangle=(\pm)
    \langle W|E^mD^n|V\rangle=(\pm)(1/\lambda)^m(1/\mu)^n
    \langle W|V\rangle
   $$
  where $m+n=N$. The two expressions cannot be equal for all
values of $\lambda$ and $\mu$. $\Box$

This shows that, following the recipe of section (\ref{mps}),
we cannot use the matrix approach. However, the l.h.s of
(\ref{algebra}) reflects directly the dynamics of the process
and does not depend on the matrix formalism, but the telescopic r.h.s.
is only inspired by the nearest neighbor nature of the dynamics
and it is more ``artificial".
In other words, if another way to solve the master equation were developed,
some kind of matrix approach could still be productive also for
those models that cannot be treated with the current matrix approach
illustrated in this paper.
