Q: Setting up production server, what user should applications run as? I'm trying to setup a production server, should I create a separate user to run certain application under similar to what apache does? Is it unsafe for them to run as root?
OS: Ubuntu 9.10
The server is for web based applications, It hosts a website but as alot of backed server process's as well

A: I prefer to have each application service run as its own user in order to have as much isolation between them as possible. If any part of the system gets broken or compromised I'd like to localise the damage as much as possible.

A: Root is the magic button.  As little as possible should run as root.
For the rest, is this a dedicated server?  That is, how many applications is it running?  Just one, pick any user.  Even run it as the web user.
You can basically think of a user as a boundary.  If everything runs as the same user (say, www) then all those things have direct access to one another.  Should one be compromised, it is all open.
However, for many uses, it doesn't matter.  Don't take this wrong, but you don't seem to be a security expert, and so I have a feeling should someone get any access to your machine, it's all over anyway.  It takes a dedicated effort to harden a machine against a dedicated attacker.
You didn't mention what language your web application is written in btw.  If Ruby on Rails, each application can easily be its own user.  If PHP, well, probably not.  Probably run those as the web user.

A: whatWhat I have each of my django instance running as separate user. This is the best way to do it. I am using Apache + WSGI Daemon process. I had earlier ran all the instances with the same user. But we had randomly faced few problems. As part of fine tuning many things I followed separating the users for each instance. Since then I am not having any problems for the past 8 months.
Like John mentioned anyways if one of your instances get compromised then all the other instances does not have to bother.

A: It is definitely ill advised to run a Python web application as root. If a specific part of the code must run as root, then you would be better off factoring that out into a separate backend service which the main web application communicates with using some interprocess communications process. That back end application should only accept connections from the host the web application runs on and not arbitrary connections from any host.
Besides that, you don't say how you are hosting Django so becomes harder to advise you if you are also after the method to isolate code to run as a specific user. Are you using mod_python, mod_wsgi, fastcgi or proxying to a backend Python WSGI server which is running it?
In worst case your only choice will be for code to run as same user that Apache runs as. This isn't advised if running other applications on same Apache, whether that be Python, PHP or some other language. This is because all the applications can interfere with each other and so a breach in a separate application can still cause you problems.
As such, running individual applications as distinct users and locking down file systems permissions such that each can only access the data for that application is preferable.
If you want an extra level of paranoia then you start looking at running individual applications in a chroot environment.
What exactly you can do is dictated by how you are hosting it, thus why important to know that.


Ubiquitous expression of ALS-causing mutations in superoxide dismutase 1 (SOD1) provoke non-cell autonomous paralytic disease. By combining ribosome affinity purification and high-throughput sequencing, a cascade of mutant SOD1-dependent, cell type-specific changes are now identified. Initial mutant-dependent damage is restricted to motor neurons and includes synapse and metabolic abnormalities, endoplasmic reticulum (ER) stress, and selective activation of the PERK arm of the unfolded protein response. PERK activation correlates with what we identify to be a naturally low level of ER chaperones in motor neurons. Early changes in astrocytes are to genes involved in inflammation and metabolism and that are targets of the PPAR and LXR transcription factors. Dysregulation of myelination and lipid signaling pathways and activation of ETS transcription factors occur in oligodendrocytes only after disease initiation. Thus, pathogenesis involves a temporal cascade of cell type selective damage initiating in motor neurons, with subsequent damage within glia driving disease propagation. Cell type-specific mRNA was purified by ribosome affinity purification from the spinal cord of bacTRAP reporter mice that label selective cell types by EGFP-tagged ribosome RPL10A. Sequencing libraries were prepared from 3-6 biological replicates for each genotype to determine the mutant induced gene expression changes in specific cell types.

My wife and I have two older granddaughters attending Georgia State University in Atlanta. The oldest is pre-law and the second granddaughter is majoring in textiles. Our son, their father, was discussing with me the incredible costs of sending those girls to school, even with scholarships, grants, loans and generous grandparents. "How much more could it cost than when you attended Mercer, I ask?" I was literally blown away. Books alone were about $600.00 for each—one semester; one semester and undergraduate at that. I am one of those guys who always purchased new books. I always said that surviving an engineering course is somewhat like earning a "badge of honor" and in my opinion, keeping your books just may come in handy as reference guides when working a real job. With that being the case, I took a look at several of the books I used as a student years ago. Are you ready for this one?
Granted, that was years ago, specifically 1961 through 1966. OK, I'm an old guy but these are undergraduate publications, the content of which has not changed that much over the years. Undergraduate work is ground zero and during that time basic foundations are hopefully established from which more detailed and specialized work is accomplished. The concepts are really not cutting edge at all.
The comparative cost of books necessary for completion of undergraduate education got my attention. I decided to take a much closer look at how university costs have risen. I was actually shocked. Here we go.
Can you imagine the debt after four years of attending a private university? Granted, a public education is considerably less expensive but still substantial. Very few families can pay outright the costs of a four year degree; wonderful if possible but somewhat rare indeed. An estimate of the actual itemized cost is shown with the next chart.
OK, where does the money come from if you are not a trust fund baby? Another look!
As you can see, approximately 50% come from Federal loans—indentured slavery.
Fewer than 12% of private college students pay those schools' high sticker prices. Fully 88% of all freshmen at private universities received scholarships to reduce their costs, according to a recent survey by the National Association of College and University Business Officers. Private college students receive, on average, $15,530 in scholarships and federal tax benefits, reducing their average net cost to $26,700, the College Board found.
Fewer than half of all public university students pay the full sticker price to attend. Federal surveys show at least 52% of all students at public four-year universities receive scholarships or grants. Aid, not counting loans or campus jobs, brought the net tuition paid by the average student at a typical public university to about $2,500, the College Board estimates. That brings the total average net cost of a year on campus (including dorm, books, travel and living expenses) to $11,400.
The really sad news– according to one study, the median starting salary for students graduating from four-year colleges in 2009 and 2010 was $27,000 a year. That's 10% lower than what those who entered the workforce from 2006 through 2008 earned. A separate study found only about 45% of college graduates under age 25 are working jobs that requires a college degree. Less than half. That number varies from major to major: Those who majored in education and teaching or engineering are much more likely to find a job requiring a college degree. But while engineering jobs are highly paid, education and teaching jobs have much lower earning potential.
And here's a sobering thought: Half the 54,000 jobs created in May of 2012 came from McDonald's.
I studied engineering, specifically mechanical engineering, because I was fascinated with the way things worked. How they were put together. What components "made them go" and go properly. How to improve designs that would allow the products to "go the distance" and perform their function well into a tenth year or even longer. In my wildest dreams, I did not realize my efforts would allow me to work to the ripe old age of 70. I unknowingly chose one profession that seems to remain in demand– regardless. Now, I have made every attempt to keep up with existing technology. You really can train old dogs to learn new tricks. If I were giving advice to an entering freshman, I would say consider the engineering profession. Consider a life in the STEM (Science, Technology, Engineering, and Mathematics) professions. These disciplines will not fade as time goes by. They will not lessen in importance. They are global in their appeal. One possible fact does worry me.
By virtue of university costs, we may be structuring a caste system n which the educated control the uneducated and using this mechanism, advances become problematic if not impossible. Some educators feel this is happening now with the remarkable elevation in costs…Just a thought.

Strictly Come Dancing 2018 results! Who left? Third celebrity voted off
Tonight's Strictly Come Dancing 2018 results
Posted October 14, 2018 20:27 by Josh Darvill
Another celebrity has left Strictly Come Dancing 2018 in tonight's results.
This weekend Strictly Come Dancing's celebrity dancers and their professional partners once again each took to the dancefloor to impress the viewers at home - as well as judges Shirley Ballas, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood in the studio.
Katie Piper and Charles Venn had to dance again and it was Katie who went home.
In tonight's Strictly Come Dancing results, the judges' scores were combined with the results of the viewers' votes to decide the lowest scoring two couples facing the dance off.
This week, that was Katie Piper and professional partner Gorka Marquez, and Charles Venn and his partner Karen Clifton.
Both couples performed their routines again, Katie and Gorka performed their Jive to Why Do Fools Fall In Love by Frankie Lymon and the Teenagers and Charles and Karen performed their Salsa to Use It Up and Wear It Out by Odyssey, in a bid to impress the judges and remain in the competition.
After both couples had danced a second time the judges delivered their verdicts with all four choosing to save Charles & Karen.
Craig said: "The best dance for me. Charles and Karen."
Darcey agreed: "The couple I would like to save for a stronger performance is Charles and Karen."
Bruno added: "The couple that stood out for me, so I would save them, is Charles and Karen."
Although her vote was not needed, Head Judge Shirley Ballas said she would also have chosen to save Charles & Karen.
After her exit, Katie said: "I have taken a lot from this experience and it has all been really positive, and I'll never forget this journey. Charles was the better dancer out of us two and there are some brilliant dancers in this competition and sadly I don't think I was one of them!
"But I have had a great experience you know and I feel really privileged to have been here and thanks for your advice and thank you (Gorka) for all the hours!
"One thing as well all the public not just the audience here but the general public have been so supportive online and have voted for me the other weeks so I feel thrilled to have been here for four weeks. So thank you to everyone."
Katie's pro partner Gorka added: "Well first of all thank you, for being such a wonderful human because you know everyone knows how much you have been through and everything...
"To get the chance to know you and be working with you and get to know how strong you are, how always wanting to be better and improve. For me that's my lesson and what I learnt from you."
The remaining twelve couples will take to the dancefloor again next week when Strictly Come Dancing returns on BBC One.

The creator of the Project video collages was born in Kraków (Poland) and currently resides in the Netherlands. She completed her Bachelor Degree in Media Art in 2009 at AKI Academy for Visual Art and Design in Enschede. She works in disciplines such as media art, mixed media, photography and video art. Light, time, mirror, projection and God are characteristic themes depicted in the artist's work, mostly projections and installations.
"Images are illusions as mirroring is never a true picture of reality."
"Our perception is inseparable from the media that makes observing possible, such as a photo camera, the eye, a mirror. Projection is a form that I regularly use in my artworks in different ways. Light is essential in my work. Caught, tamed, guided by various media and devices that I sometimes build myself. The result is always a combination of the dimensions of time and movement. An image is created by painting with light in time."

Climate change denier leads panel

Climate threat doubter is leading effort to advise Trump
By KEVIN FREKING and SETH BORENSTEIN
WASHINGTON (AP) — The Trump administration is exploring the idea of forming a special committee to look at climate change and security risks, with the effort being coordinated by a 79-year-old physicist who rejects mainstream climate science.
A "discussion paper" obtained by The Associated Press asks federal officials from an array of government agencies to weigh in on a proposed executive order that President Donald Trump would sign establishing the "Presidential Committee on Climate Security."
A memo to those federal officials asks them to direct any questions to William Happer, a member of Trump's National Security Council and a well-known critic of mainstream climate science findings.
"Happer would be a fringe figure even for climate skeptics," said retired U.S. Navy Rear Adm. David Titley, now a professor of meteorology at Pennsylvania State University.
Several climate scientists agreed with Titley, including Georgia Tech's Kim Cobb, who said Happer's "false, unscientific notions about climate change represent a danger to the American people."
Harvard science historian Naomi Oreskes, who wrote the book "Merchants of Doubt" on climate denial, pointed to instances when Happer has claimed that carbon dioxide, the main heat-trapping gas from the burning of coal, oil and gas, is good for humans and that carbon emissions have been demonized like "the poor Jews under Hitler."
Happer's bio at Princeton University, where he previously taught, describes him as a pioneer in the field of optically polarized atoms. It notes that he served in the administration of President George H.W. Bush as the director of energy research at the Department of Energy, where he oversaw a basic research budget of roughly $3 billion.
The National Security Council advises the president on security and foreign policy issues. According to the discussion paper, the council would fund and oversee the committee. Among the committee's responsibilities would be to "address existing United States Government reports on climate for scientific accuracy and advise on the national security implications of climate change."
The committee would be composed of 12 members, according to a draft of the executive order. Members would include experts in national security and climate science. The panel would advise the president on how climate "might change in the future under natural and human influences."
A spokesman for the National Security Council declined to comment.
The Washington Post first reported on the proposed executive order establishing the climate security committee.
Trump once tweeted that climate change was a "Chinese hoax." More recently, he used a cold snap that hit much of the nation last month to again cast doubts. "People can't last outside even for minutes. What the hell is going on with Global Waming (sic)? Please come back fast, we need you!" he tweeted.
Both the Pentagon and the president's intelligence team have mentioned climate change as a national security threat, and a 2018 National Climate Assessment detailed drastic effects of global warming.
Over about a dozen years, government scientists, military leaders and intelligence experts have repeatedly highlighted climate change as a major national security risk, said Titley, who founded one such study team in the Navy.
Titley said these studies have come to the same conclusions under three presidents, including two Republicans. He said there are "a surprising number of documents from the Pentagon and intelligence community after January 2017 (when Trump took office) that talk about climate and security risk."
"For the Pentagon, it's about readiness," Titley said. "For the intelligence community, it's about risks. We see the risks are accelerating."
Climate change can "push a marginally stable area into chaos," Titley said, mentioning Syria, which suffered a record drought at the same time as a civil war that triggered a migration of a million people.
Francesco "Frank" Femia, chief executive of a think tank that reviews systemic risk to national and international security, expressed concern that the proposed panel was meant to poke holes in future government reports and studies.
"I would welcome a serious study commissioned by the White House on the security implications on climate change that include climate scientists and national security experts, but this is not that," said Femia, the CEO of The Council on Strategic Risks.
A place like the National Academy of Sciences was set up just for that type of study, said Zeke Hausfather, a climate scientist at Berkeley Earth, which monitors global temperatures.
"The ice doesn't care what this administration thinks," Titley said. "It's just going to keep melting and obeying the laws of physics, whatever Will Happer wants."
Justice Thomas calls for re-examining landmark libel case
By MARK SHERMAN
WASHINGTON (AP) — Justice Clarence Thomas says the Supreme Court should consider overturning a 55-year-old landmark ruling that makes it hard for public figures to win libel suits, writing in a case involving a woman who says Bill Cosby raped her.
Thomas took aim at New York Times v. Sullivan and similar cases that followed it, calling them "policy-driven decisions masquerading as constitutional law."
"We should not continue to reflexively apply this policy-driven approach to the Constitution," Thomas wrote in a 14-page opinion that no other justice joined.
The opinion comes against the backdrop of President Donald Trump's repeated calls to make it easier to sue for libel. Last weekend, Trump reacted to a Saturday Night Live skit by asking on Twitter, "How do the Networks get away with these total Republican hit jobs without retribution? Likewise for many other shows? Very unfair and should be looked into."
On Tuesday, the high court rejected an appeal from actress Kathrine McKee, who said Cosby raped her in 1974. McKee sued Cosby for damaging her reputation after a lawyer for the comedian allegedly leaked a letter attacking McKee. Two lower courts ruled against her and dismissed the case, based largely on McKee's role as a public figure.
The Sullivan case set a very high bar for public officials to win a libel suit and hefty money awards over published false statements that damaged their reputations. The high court extended the 1964 decision in the ensuing decades to make it tough for celebrities, politicians and other public figures to win defamation cases.
Thomas is the justice who most often calls for jettisoning Supreme Court rulings that he says do not comport with the meaning of the Constitution at the time it was adopted.
"The states are perfectly capable of striking an acceptable balance between encouraging robust public discourse and providing a meaningful remedy for reputational harm," he wrote.
He is not the first justice to criticize the 1964 case, though he appears to be the first to issue a call for its reconsideration in a Supreme Court opinion. The late Justice Antonin Scalia took a similarly dim view of the Sullivan ruling, once saying in a televised interview that he abhorred it.
The revolving door between media and government spins again with CNN's hiring of Sarah Isgur Flores
Author: Michael J. Socolow, Associate Professor, Communication and Journalism, University of Maine
Disclosure statement: Michael J. Socolow receives funding from the Fulbright Scholar Program. He is currently a Fulbright Scholar at the News & Media Research Centre at the University of Canberra (Australia).
A common practice in American journalism has, once again, sparked outrage.
CNN recently announced the hiring of Sarah Isgur Flores to be "one of several editors" who will help "coordinate [political] coverage across TV and digital."
Though a CNN spokesman explained to news site Splinter that Isgur "is not leading, overseeing, or running CNN's political coverage," the new hire will undoubtedly influence the cable network's coverage of the 2020 presidential election.
Isgur has no professional journalism experience. But she's been active politically, which may have qualified her for the job.
Isgur most recently worked as the spokesperson for the Department of Justice, where she disseminated information about the department's new policies under President Trump and Attorney General Sessions in order to inform and influence journalistic coverage.
With a Harvard law degree, and jobs at the Republican National Committee and on numerous Republican campaigns, she was a reliable purveyor of administration spin.
CNN's hiring of Isgur immediately provoked criticism.
"Elevating an unabashed partisan to a nonpartisan role is an obvious disservice to viewers at home, who count on the network's independence," wrote attorney and GQ columnist Jay Willis.
Media history shows that CNN is simply repeating a time-honored journalistic hiring practice. The revolving door from the White House to mainstream journalism, and from mainstream journalism to the White House, has been used so regularly that we often forget just how common it was – and remains.
The long list of political operatives who transitioned into journalism includes such well-known figures as Bill Moyers, William Safire, Diane Sawyer and George Stephanopoulos.
Perhaps the most illuminating example of this transition is Moyers. While working as a special assistant and press secretary for President Lyndon Johnson, Moyers proved to be one of the administration's most antagonistic tacticians in dealing with the media.
In a memo he wrote about Vietnam War coverage, Moyers decried "the irresponsible and prejudiced coverage of men like Peter Arnett and Morley Safer, men who are not American and who do not have the basic American interest at heart." Arnett was from New Zealand and Safer from Canada.
Safer, the legendary CBS News reporter, never forgave Moyers for helping the Johnson administration smear him as a Communist.
FOIA records later revealed that Moyers helped hunt for homosexuals serving in the Johnson administration in order to protect the White House from embarrassing disclosures. Moyers has disputed that characterization.
Yet, for all of Moyers' partisan political behavior, he would transition straight from the White House to become publisher of the Long Island newspaper Newsday in 1967. He joined CBS News in 1976.
Following in Moyers' footsteps were several Republican political appointees.
Diane Sawyer easily moved from working for Richard Nixon to a job at CBS News without much criticism. William Safire's hiring by The New York Times as an opinion columnist in 1973 sparked a firestorm of controversy both in the newsroom and from critics.
Safire had composed the most memorable phrases uttered by Spiro Agnew in that vice president's famous attacks on the press. Just a few years later, he would win journalism's highest honor – the Pulitzer Prize for his commentary on the Carter administration.
But not all the revolving-door examples would be as famous as Moyers, Sawyer or Safire.
In 1997, for example, David Shipley left a position as special assistant to President Clinton to join The New York Times as deputy op-ed page editor. Roger Colloff, who served in the Federal Office of Energy under President Carter, left the administration in 1979 to join CBS, where he would become a CBS News vice president with supervisory authority over all public affairs broadcasts, including "60 Minutes."
Journalistic independence questioned
Isgur won't simply be a columnist (like Safire) or reporter (like Moyers or Sawyer). Both Shipley and Colloff had previous journalistic experience; Isgur doesn't.
The danger critics identify is that Isgur, as an editor, could supervise and shape coverage in ways that might allow her evident political biases to go unchecked. CNN characterized her authority as limited, specifically noting that Isgur ""is helping to coordinate coverage across TV and Digital – she is one of several editors."."
Yet there are historical precedents for granting far more authority to former political appointees than Isgur will have.
Colloff went from the Carter administration to supervising all public affairs coverage at CBS, including the celebrated investigations of "60 Minutes."
In 1961, James C. Hagerty moved from his position as President Eisenhower's press secretary to vice president of news, special events and public affairs for ABC. There's little evidence that Hagerty's ABC News management led to significantly more favorable coverage of Republicans, when compared to CBS News and NBC News, in this period.
Do these historical examples demonstrating the smooth interplay between American politics and political journalism apply in the Isgur case?
Today's context is different. Isgur comes from an administration that has vilified the press to an unmatched degree. President Trump's rhetorical attacks on the media, which have led to several violent and criminal acts, this line of thinking goes, should therefore disqualify administration appointees from working in journalism.
There's some truth to the idea that President Trump is uniquely antagonistic towards the media. But he's not the first high-level politician to be that way.
After more than four decades, it's easy to forget the power and influence of vice president Spiro Agnew's attacks on the media during the Nixon administration. And, even before that, at the 1964 Republican convention in San Francisco, the "right-wing rage" directed toward the media shocked journalists.
Just as Safire's defection from the Nixon administration to The New York Times raised the issue of hypocrisy, Flores' parallel move incites many of the same questions.
Why would a Trump administration appointee even be interested in working for CNN, a journalistic outlet the president has accused of purveying "fake news"? Is the move an implicit recognition that the attacks on the media are exploitative, done primarily to rile a political base?
Questioning the coziness
There's always been a close relationship between American political coverage and American political journalism – but to acknowledge it neither endorses nor excuses it.
The First Amendment guarantee of an independent press is philosophically grounded in the ideal of journalistic independence. When the revolving door is utilized, it's healthy to criticize its use. Noting that political operatives might bring their biases to their coverage, critics can pressure these novice journalists to be more circumspect about their work.
Perhaps ironically, CNN's public announcement of Isgur's hiring provides a remedy for the network's critics of the hiring. Drawing attention to the move will help the CNN audience evaluate her work.
The audience plays an important role in safeguarding journalistic ethics in a democracy. If viewers watch CNN with a more skeptical and critical perspective throughout the 2020 presidential election, the network will be forced to respond.
Should coverage become detectably more in favor of the Trump administration, criticism spawned by vigilance will likely hurt CNN's reputation for independence, its credibility and its ratings.
That's a lesson liberals in the United States might learn from conservatives, who have complained about liberal bias for decades. Pressure often works.
In fact, it's quite possible that such criticism ultimately elevated a person with no journalism experience to one of the most important and coveted jobs in the industry.
Gigi Marino: Lest we forget that when William Safire worked for Spiro Agnew, Safire referred to the media as "nattering nabobs of negativity."
James Wittebols, Professor of Political Science, University of Windsor: There was a Bush cousin helping to make calls on state votes in the 2000 campaign and had influence in making the Florida call for Bush. Probably the most consequential example of a political hack influencing journalism.

Marine Cyanobacteria Shed Billions of DNA-Containing Vesicles
By James Fenner on January 11, 2014 5 Comments
Scientists have recently discovered and documented the first extracellular, DNA-containing vesicles shed by ocean microbes. The marine cyanobacteria – photosynthesizing, prokaryotic bacteria that are ubiquitous to most terrestrial and aquatic habitats – are involved in Earth's biogeochemical and nutrient cycles. During photosynthesis, the bacteria harness sunlight to convert light energy into chemical energy, using carbon dioxide and water and releasing molecular oxygen as a byproduct. Essentially, they provide a source of nourishment for other organisms, constituting an edible form of biomass.
Scientists at the Massachusetts Institute of Technology (MIT) have discovered another potential role of cyanobacteria. They have confirmed that the bacteria manufacture and release tiny spherical packages containing a host of substances, including genetic material – which can be transferred via horizontal gene transfer – and nutrients.
Autofluorescence seen in synechococcus bacteria.
The latest research was published by post doctorate researcher Steven Biller and Professor Sallie Chisholm, along with their co-authors, in the journal Science. The afore-mentioned vesicles were identified in two different types of cyanobacteria – Prochlorococcus and Synechococcus.
Prochlorococcus is a genus of remarkably small bacteria, less than a micrometer in length, that was discovered over 20 years ago. As the smallest known photosynthetic organism, Prochlorococcus is conjectured to be one of the most abundant photosynthesizing bacteria, surviving along the oceanic surface and to depths of 200 meters. Meanwhile, Synechococcus thrives in oligotrophic environments, and are capable of surviving in conditions where nutrient levels are scant; however, the bacteria remain confined to salt water and are more abundant in nutrient-rich areas.
When scrutinizing the bacteria a little closer, the researchers identified a series of vesicles that were just 100 nanometers in diameter, suspended in the cyanobacteria cultures. Similarly, this observation was also made in seawater samples that had been gathered from the nutrient-rich coast of New England and the nutrient- bereft waters of the Sargasso Sea, situated in the middle of the North Atlantic Ocean.
Vesicle-Mediated Transfer Between Bacteria
Biller calls for further research to be conducted into these vesicles, so the scientific community might better understand their nature and function, before going on to tentatively posit their role in disseminating DNA and other organic material:
"Vesicles are a previously unrecognized and unexplored component of the dissolved organic carbon in marine ecosystems, and they could prove to be an important vehicle for genetic and biogeochemical exchange in the oceans."
Following metagenomic analysis of the vesicles' contents, from seawater samples, Biller and colleagues found DNA that originated from a diverse range of bacteria; the authors believe, on this basis, that vesicle production and release is relatively common among marine cyanobacteria.
The team approximated the global production of vesicles from Prochlorococcus to be around a billion billion billion each day, contributing considerable amounts of carbon to – what they describe as – the "… scarce nutrient pool of the open seas".
Additional laboratory investigation demonstrated that the vesicles were stable and could endure for two weeks, or longer. It's possible that the sheer number of vesicles released could provide sufficient nutrients to sustain the growth of nonphotosynthetic bacteria.
In explaining these startling findings, Chisholm explains that Prochlorococcus no longer possesses the capacity to effectively neutralize particular toxic chemicals; instead, cyanobacteria remain reliant on nonphotosynthetic bacteria to eliminate the toxins. It would seem that Prochlorococcus and nonphotosynthetic bacteria have developed a mutually beneficial relationship; nonphotosynthetic bacteria provide safety to Prochlorococcus, in exchange for vesicles of nutrients.
Protection From Viral Invaders
Structure of a typical bacteriophage.
When studying the vesicles using electron microscopy (EM), the researchers made another intriguing discovery. Affixed to the small, DNA-containing packets were bacteria-attacking viruses, called bacteriophages (a.k.a. phages). These viruses insert their genome into the cytoplasm of the bacteria and use the host's own cellular machinery for replicating new virions.
Biller indicates that, once a phage has injected its DNA into a vesicle, the phage is then entirely inactive. Equating the vesicles to the countermeasures deployed by fighter jets to ward off missile attacks, Biller suggests that the vesicles could help nullify the deadly threat from phages.
The vesicles were originally discovered by graduate student Anne Thompson, back in 2008. Thompson observed small blebs protruding from the surface of the bacteria, during high resolution EM analysis, and shared her remarkable findings with Chisholm, who works in MIT's Department of Civil and Environmental Engineering and Department of Biology. Once Biller came aboard, the researchers found that the marine cyanobacteria shed billions of these small blebs, which they eventually identified as DNA-containing vesicles.
As of yet, however, the mechanisms by which these vesicles are created remains poorly understood. In addition, the researchers are uncertain as to how they come to contain genetic material.
Having already dedicated three years to the latest study, Biller and colleagues plan to continue researching these tiny vesicles in further detail; however, they suggest it could take up to another five years before they gain a more definitive understanding.

One more thing. I do believe that there are quite a few travel insurance websites of trustworthy companies that allow you to enter your vacation details and acquire you the prices. You can also purchase the international holiday insurance policy on the net by using your credit card. Everything you should do is always to enter all travel details and you can be aware of the plans side-by-side. Merely find the plan that suits your financial budget and needs after which it use your bank credit card to buy it. Travel insurance on the internet is a good way to check for a respectable company for international travel insurance. Thanks for giving your ideas.

Prochlorococcus was "discovered" much longer earlier than 10 years ago:
SW Chisholm, SL Frankel, R Goericke, RJ Olson, B Palenik, JB Waterbury, L Westjohnsrud, and ER Zettler (1992).
Prochlorococcus marinus nov. gen. nov. sp.: An oxyphototrophic marine prokaryote containing divinyl chlorophyll a and chlorophyll b.
Archives of Microbiology 157(3):297-300, Feb. 1992.
Additionally, it is Pro. that is found in oligotrophic waters, while Syn. is more common in near shore waters with higher nutrients.
James Fenner January 11, 2014 at 8:01 pm
Hi Melinda,
You're absolutely correct, prochlorococcus was discovered earlier than 10 years ago; I'll have this fixed.
With regards to the other points, I didn't state whether Pro. was or wasn't common to oligotrophic waters. Also, I stated that Syn. thrived in oligotrophic waters. According to one of my sources, Syn. bacteria do occupy oligotrophic waters, and is the main source of primary production in these regions. However, I do accept that this point could be made clearer, and updated to reflect their ubiquity is greater in nutrient-rich waters. I will make sure the article is updated when I return to my desk.
Thanks for taking the time to comment. It's really appreciated.

Three people have tested positive for coronavirus, the Health Ministry said on Sunday, updating its earlier announcement in which it had said that no new cases had been reported. The ministry said that 58 additional tests were completed late on Sunday afternoon from repatriations. Three positive cases were reported. Protocols have been activated regarding tracing of close contacts. Two of the three cases had returned from London yesterday. The third is a crew member who was tested as part of regular tests of crew members and had returned to Cyprus on a flight from Greece yesterday. This brings the total number of tests today to 1252 and the total number of positive cases in Cyprus to 983.
Turkish Cypriot leader Mustafa Akinci on Sunday called on scientists in the north to speak up about the coronavirus situation in Turkey, which he said was even worrying health experts there. Turkey has confirmed 176,677 cases and has seen 4,792 deaths from Covid-19. The number of new coronavirus cases there rose to 1,459 on Saturday from 1,195 a day earlier, increasing after travel restrictions were lifted and facilities reopened at the start of the month, according to Reuters. The daily number of cases had previously been below 1,000 since late May. In the 24 hours between Friday and Saturday, 14 people died, bringing total fatalities to 4,792. In a written statement, Akinci called on Turkish Cypriot health experts to express their views. "Are our scientists not worried about July 1?" he asked referring to the date that flights between Turkey and the north are due to resume. "We are going through a period in which it is important and mandatory for health professionals to express their views publicly and strongly as we expect them to guide the politics [of the situation]," Akinci added. "Transport and communication with Turkey is undoubtedly crucial. However, we have a responsibility to protect the health of our people above all."
The zero cases COVID-19 trend in the occupied north continued, with 'health minister' Ali Pilli reporting that no new cases were found out of a total of 21 tests over the past 24 hours.
Authorities continued their intensified checks on night clubs, bars and restaurants for Covid-19 violations, according to the revised health ministry protocols. As of Friday evening, police conducted almost 1200 checks, charging 60 night spots with various violations. Over the past 24 hours, 711 checks were conducted, with 12 businesses charged. In most cases, they did not have the necessary protection signalling or personnel were not wearing protective masks and gloves. In addition, 21 businesses were charged for operating without loudspeaker or alcohol license. Some did have operating licenses from the relevant authority. On Friday, 479 businesses were checked, with 6 charged for Covid violations, including two concerning a greater number of people than what is allowed in revised healthy ministry directives. Police said they will continue intensified checks in all cities, ensuring the implementation of both Covid and other legislation on night spots.

This week we were looking at F.
We concentrated on two animals, frogs, and fish.
This included a trip to the frog pond..
..where unfortunately we didn't get to see any frogs this time, but we did get to learn about the frog life-cycle.
We have been reading fictional books about frogs and fish….
'Fish is fish' (Leo Lionni) is the absolute favourite, which is great, because it is about both frogs and fish!

[The Hwankyung Ilbo] The Seoul Metropolitan Government will select the five most frequently used plastic items in daily life and launch a continuous civic real-life campaign with civic groups, in order to reduce the annual increase in plastic use.
The five items are plastic cups, straws, plastic bags, delivery goods, and laundry vinyl.
In particular, the amount of plastic used in Korea is 132.7kg per capita in 2016, which is much higher than the 93.8kg in the US and 65.8kg in Japan.
On August 26 last year, Seoul held a volunteer action campaign with the Saemaul Women's Association, the Korean Woman's Federation for Consumer, the Ecofeminist, and the Green. Each organization has carried out a variety of activities to reduce the use of plastic, especially the five items.
In addition, Seoul plans to continue carrying out the campaigns to reduce the use of plastic items with civic groups, and it will hold discussions on the performance of each civic group to find ways to improve the situation.


The exciting part of buying a car is always the purchase. The less exciting but no less important aspect is car maintenance.
It's extremely important to keep your car in good working order to ensure that you're able to get where you need to go at any time.
A few of the most common issues to keep an eye out for can be easily handled with the right knowledge.
Surprisingly, how to change a tire is one of the most frequently asked questions by car owners. The good news is that changing a tire on your Toyota Corolla is actually very simple.
If you find yourself with a flat tire, first you'll need to pull over. Make sure your Corolla is in a safe location before beginning any work.
Next, remove the hubcap on the wheel. This will give you access to the tire and allow you to loosen the lug nuts.
Once this is done, jack your car up. It's important to get your car up to about 6 inches high. Be sure not to place the jack in a position that could cause damage to your vehicle.
Now you're ready to remove the tire. Take the lug nuts off (but keep them handy!) and pull the tire straight towards you.
Finally, place the new tire on the car. Push the tire straight on, and fasten your lug nuts to secure it in place.
Begin by sliding the oil pan under the drain plug. The drain plug is located below the engine.
Next, use a wrench to remove the drain plug. The oil will drain into the oil pan. Once the drainage is finished, you need to remove the oil filter.
Use your rag to wipe away the oil from the filter. Now take a clean rag, add some oil to it, and wipe the edge of the new filter.
You can now install the new filter and replace the drain plug. Next, open the oil tank and pour in the new oil.
Give the car a moment before using the dipstick to make sure you have enough oil inside.
Voila! Just like that, you've changed the oil. Make sure to close the oil tank again once you are finished.
The wiper fluid level is another part of your vehicle that needs to be continuously checked. Windshield wiper fluid isn't crucial, but not filling it can certainly lead to a messy car!
To refill the wiper fluid, you don't need to do a whole lot. First, remove the front bumper so that you can access the wiper fluid pump.
Next, remove the wiper fluid pump from the reservoir. Discard the reservoir, open a new one, and insert the pump into the new reservoir.
Put all the parts back into place and close the bumper again.
While car maintenance is key to keeping your vehicle running, it's best to get a healthy vehicle in the first place. Give us a call today to get a car in tip-top shape!

Go, speedrunners, go!
Donate to a good cause. And save the animals. Always. Screen grab from Awesome Games Done Quick 2015 video.
So you know that we here at Otaku Ohana love our video games. And gamers don't often have the greatest reputation — you know the stereotypes, which I won't deign to repeat here. You also know we love our charity gaming events — see our past coverage of Child's Play Charity, which helps children's hospitals worldwide.
But the idea of using video games as a fundraiser has been around for years, and lately it's been getting more mainstream recognition. A subgenre of this is the speedrunning category, in which gamers finish games as fast as they can — exploiting things like glitches and technical aspects of games to complete them in mere minutes to several hours instead of the, say, 80 hours we mere mortals probably spent. (Yeah, that was me with Final Fantasy III/VI. But only because I was trying my darnedest to get Economizers for everyone so they could all cast spells for a measly 1 magic point! Anyway, I digress.)
Admittedly, I'd never heard of speedrunning until just a few years ago when I stumbled across a particular video game marathon for charity. Seeing the insane skills and the vast knowledge that the gamers had to employ to effortlessly whip through these games like Simon Belmont through Dracula, the same games that I loved and sweated and cursed over and spent wayyyyy too much of my life — that got me COMPLETELY hooked. And the fact that this was being done to benefit a worthy cause was a big, big bonus.
It's only in the past few months that I became aware of various other video game marathon charity events, both speedrunning and otherwise, and I'd like to spread the word about them by sharing them here. These broadcast live online, usually via Twitch, and they're listed here in generally chronological order. (Please note that the months listed are only an estimate based on when they occurred last year and that they may change.) Check them out and, if you can, please donate to their cause! Remember, even a dollar is a big help. Even if you're not able to donate, you can help by talking about them on social media and raising awareness about them and the causes they support.
With most of these events, your money goes directly to the chosen charity and is tax-deductible. But be sure to check with the charity for information for tax purposes.
Awesome Games Done Quick / Summer Games Done Quick
Held in January and summertime
>> Website: gamesdonequick.com
>> Facebook: facebook.com/GamesDoneQuick
>> Twitter: twitter.com/gamesdonequick
>> Hashtags: #AGDQYYYY, #SGDQYYYY (replace "YYYY" with the appropriate year that the event is taking place)
Possibly the grandaddy of all speedrunning charity marathons and the one that introduced me to speedrunning, Games Done Quick holds two weeklong events yearly: Awesome Games Done Quick sometime in January, which benefits the Prevent Cancer Foundation; and Summer Games Done Quick, held, well, sometime during the summer (this year it's going to be from July 3 to 10) to benefit Doctors Without Borders (Medicins Sans Frontieres). The games played range from platformers to action-adventure to role-playing, from classic games to new releases, so there will probably be something that will catch your attention.
At the time of donation, donors have the option of putting their money toward various incentives. Many of them are options to name characters or game files (the one with the most money at the cutoff time wins) or to do even MORE crazy things in the games, like show off glitches or finish the game using a particular character or move, or even to put certain limits on the gamer. Bonus incentives are also often added throughout the marathon, so check the schedule once in a while to see if there's anything new. The mother of all incentives is a bid war related to Super Metroid — there's a path near the end where animals can be rescued or ignored, depending on the whim of donors — and it's become so popular that it causes some fierce competition and usually raises the most amount of money. The most recent AGDQ raised $1.2 million for the Prevent Cancer Foundation, with the Super Metroid incentive raising $313,000 alone.
Donors are also eligible to win any number of cool prizes, which you can check out on the site. In addition to smaller items donated by the community — including beadsprite game characters, handmade apparel, video games, game accessories, artwork, and lots more — there's usually a grand prize (or several) that you can be eligible for if you donate a minimum amount.
This event has been going since 2009 and has raised a collective total of more than $5 million for its charities.
The mad skillz these gamers show will utterly blow your mind. As an example, here's a video from AGDQ 2015 of a 4-player Tetris: The Grandmaster exhibition. If you thought you were good at Tetris, this will show that YOU KNOW NOTHING, JON SNOW — Sorry, wrong "Game."
Not convinced? How about some Mike Tyson's Punch-Out? Finished in less than 30 minutes? While BLINDFOLDED? (The actual run starts at around 29 minutes into the video, but the interview with the runners beforehand gives a lot of information about all the strategy that you never realized was involved in speedrunning. Start watching around 22 minutes for a little bit of pre-game humor.)
If you want to see more, check out the Games Done Quick channel on YouTube. I absolutely love watching that Punch-Out video over and over even though I have a ton of other videos from previous GDQ events in the archive to go through. The event itself has a lot of energy and humor and nostalgia, and the runners are both awesome as gamers and as commentators, so you'll be laughing and shaking your head at just how quickly they get through areas that probably stymied you when you were playing that game. All of this makes Games Done Quick the king of gaming charity events, and I highly suggest you catch at least part of it when you can.
RPG Limit Break
Held in May
>> Website: rpglimitbreak.com
>> Twitter: twitter.com/RPGLimitBreak
>> Hashtags: #RPGLBYYYY (replace "YYYY" with the appropriate year that the event is taking place)
This weeklong event is streaming right now — it ends on Sunday (or rather Saturday, Hawaii time) — to benefit the National Alliance on Mental Illness, so head on over to their website for a peek! A similar format to Games Done Quick, this one, as its name says, focuses on speedrunning role-playing games. (Yes, of COURSE Final Fantasy games are part of the schedule, what are you thinking?) As such, not as many games are played during the week that it broadcasts (those of you who've played RPGs know the many HOURS it takes to beat just ONE game the normal way). Like GDQ, there are lots of donation incentives and prizes available.
By the way, NAMI has a great post from last year talking about gamers, speedrunning, and the charity events in general. It focuses on RPGLB, but the things it discusses, such as donation incentives, also hold true for Games Done Quick.
Zeldathon
Held in summer and fall/winter
>> Website: zeldathon.net
>> Facebook: facebook.com/zeldathon
>> Twitter: twitter.com/Zeldathons
I was informed of this non-speedrun event just last year, although it's been happening since 2009 (with some interruptions). As its name suggests, it focuses on various games from the Legend of Zelda series (and there are a lot of them). It's held twice a year and each event partners with a different charity — last year's winter marathon raised money for HelpHOPELive, which helps patients with medical costs that are not covered by insurance. (I donated during that one and they read my donation on the stream! *fangirl squee*) Like other gaming marathons, Zeldathon has donation incentives allowing viewers to "unlock" more games to be played.
Even though I wasn't able to watch as much of this marathon as I would have liked, I got a kick out of what I did manage to see because they played the less-popular games in the Zelda series, games that I myself played and loved, such as Oracle of Seasons, which they played on AN ACTUAL GAME BOY. I probably got more of a kick out of seeing that Game Boy than I did the actual game, haha! The 2015 winter marathon even had the rare and much-maligned Philips CD-i games Wand of Gamelon, Faces of Evil and Zelda's Adventure — I sorely wished I could have watched those because I've heard so much about how BAD those games are.
The website is a bit sparse, and they seem to delete their schedule at the end of each event, so it's hard to gauge past marathons. The next Zeldathon is slated to begin June 17 in support of Direct Relief, a humanitarian health organization. The event's Twitter profile says it's raised more than $875,000 over the years, so mark your calendars and let's help bring them closer to that magic $1 million!
Desert Bus for Hope
Held in November

>> Hashtags: Not sure if they have an "official" one, but I've been using #desertbus in my tweets
This is an interesting event I came across a year or so ago that benefits the previously mentioned Child's Play Charity. There's a game you've probably never heard of called Desert Bus, and… Well, you know, the fine people over at event organizers LoadingReadyRun made this video that perfectly explains things better and more humorously than I would be able to:
The team basically plays the game for as long as people keep donating. However, the money needed to make the team play for another hour rises by 7 percent. The first hour costs $1, so the second hour costs $1.07, and so on. They've put together a handy chart at the bottom of the page here so you can see how that works out.
This one isn't as exciting as the speedrunning marathons, as it can be a long time between episodes of crazy hijinks depending on how donations flow. But they do occasionally have special guests visit or call in, and auctions are held throughout the event. And come on, they're sacrificing themselves to play a really horrible game for DAYS on end, all for charity, so go on and give 'em a few bucks to ease their pain!
LoadingReadyRun has also started a Kickstarter project to fund a documentary of their 10 years in operation. Check it out and give to the project on the Kickstarter site. At the point it's been fully funded but it ends May 20, so there's still time for you to pledge.
Nick's Marathon

>> Facebook: facebook.com/NicksMarathon
>> Twitter: twitter.com/nicksmarathon
This event is in honor of an avid gamer named Nicholas Capobianco who was diagnosed with leukemia at age 3. The cancer went into remission but returned more than 20 years later; Nicholas died in 2008.
Every year, a group of Nicholas's friends do a live stream on Ustream in which they marathon video games for 48 hours, and donors can give to benefit the Ronald McDonald House of Long Island. The roster of games changes each year.
Although Nick's Marathon has been going since 2008, I heard of it only in 2014 and unfortunately have not been able to catch any of their broadcasts, but it doesn't seem to be a speedrunning marathon.
As I write this part, the Nick's Marathon website seems to be down so I don't have any more details on their format or other information, but they are also on Facebook and Twitter, so you can head over there for the latest news. As far as I can tell, the 2016 event is planned but no dates have been set.
Sonic Marathon
Held December-January
>> Website: respawn-point.com/sonicmarathon/index.html (seems to be blank)
>> Facebook: facebook.com/pointrespawn
>> Twitter: twitter.com/respawn_point
Tag-team partner in fandom Jason Y. discovered this just in December while Zeldathon was going on. Organized by Respawn Point, this time gamers play through various games from the Sonic the Hedgehog series in a weeklong marathon. I caught only a few minutes of last year's event, which benefited Special Effect, a UK organization that creates special tools and devices to help the disabled play games. Unfortunately, their website is coming up as blank right now so I have no other information, nor am I certain if it's speedrunning or not (though I'm leaning more toward "not"). This event has been going for three years but nothing has been said about whether there will be one this year. Still, it's worth it to keep an ear out for any upcoming news, especially if you're a Sonic fan. Check out their Facebook or Twitter.
Child's Play Charity
Held in December
>> Website: childsplaycharity.org
>> Facebook: facebook.com/ChildsPlayCharity
>> Twitter: twitter.com/cpcharity
I'd be remiss not to mention the organization that first made me aware of game-related charities. Active year-round but really in gear during the holiday season, Child's Play helps children's hospitals around the world — including the Kapiolani Medical Center for Women and Children here in Hawaii — set up wish lists of games, toys and other items that their young patients could use. Donors visit a hospital's wish list on Amazon.com and buy items that are then sent directly to the hospital. Child's Play also receives cash donations that are used to buy games, consoles, and toys for medical facilities. As you can see from their events calendar, there are tons of gaming events that help out this very worthy charity.
Of course, there are very likely other online events out there that haven't been covered here, so if you know of one, please comment below with a link! There are also lots of mini events through the year done by individual Twitch streamers, far too many to mention, but kudos to each and every one of you — organizers, gamers, and donors alike — for helping some great causes and having a lot of fun while doing so.

Éloïse de Volayne was a very beautiful but despotic tempered orphan, who used to live on top of Cape Diamond. Laughing at her suitors, she declared that she will marry the first man who climbs the cliff on horseback. At that time, two brothers, Jean and Samuel, were madly in love with her so they both decided to take up the challenge. Unfortunately they both failed and fell off from the cliff which discouraged others.
Few years later Éloïse met Henri de Villemontel. A young man showed up once at her mansion willing to pick up the gauntlet, however as the fog prevented any climbing for three days, Éloïse and Henri spent the time together. Charming and distinguished stranger totally stole her heart. Éloïse afraid to lose the loved one, begged Henri to resign from the challenge, however he didn't want to listen to her and eventually he made it to the top on horseback. When she rushed towards him, he pushed her away. The real name of Henri de Villemontel was Henri de Rochebeaucourt, brother of Jean and Samuel, who decided to avenge them.
With broken heart Éloïse watched Henri's boat sail away. When she yelled and stretched out her arms, she lost the balance and fell off from the cliff.
It is said that since that time, the ghost of a woman can be seen in autumn as she comes back to cry over the love she won and lost because of her cruelty and on 1st November at midnight you can hear as she screams when her misty silhouette fades away along the cliff.

Taking graphics cards beyond gaming

A highly efficient mathematical solver designed to run on graphics processors gives scientists and engineers a powerful new tool for a common computational problem.

The graphics cards found in powerful gaming computers are now capable of solving computationally intensive mathematical problems common in science and engineering applications, thanks to a new solver developed by researchers from the KAUST Extreme Computing Research Center1.
"One of the most common problems in scientific and engineering computing is solving systems of multiple simultaneous equations involving thousands to millions of variables," said David Keyes, KAUST Professor of Applied Mathematics and Computational Science, who also led the research team. "This type of problem comes up in statistics, optimization, electrostatics, chemistry, and mechanics of solid bodies on Earth and gravitational interactions among celestial bodies in space."
In typical applications, solving such problems is often the main computational cost. Thus, acceleration of the solver has the potential to considerably impact both the execution time and the energy consumption required to solve the problem.
"Graphics processing units (GPUs) are very energy efficient compared with standard high-performance processors because they eliminate a lot of the hardware required for standard processors to execute general-purpose code," explained Keyes. "However, GPUs are new enough that their supporting software remains immature. With the expertise of Ali Charara, a Ph.D. student in the Center who spent several months as an intern at NVIDIA in California, we have been able to identify many things that we can either innovate or improve upon, such as redesigning a common solver."
The key to making a more efficient solver is maximizing the trade-off between the number of processors and the memory available to temporarily store the computational data. Memory remains expensive, so finding a way to execute more computation using less memory is critical to solving the problem of computational cost.
"Charara designed a solver scheme that operates directly on data 'in place' without making an extra copy," explained Dr. Hatem Ltaief, a Senior Research Scientist from the project's team. "This means a system twice as large can be stored in the same amount of memory."
Usually, operations on simultaneous equations are carried out by progressing sequentially over columns in the data of the matrix of values derived from the equations. Charara converted the columns into a series of tasks on small, computationally efficient, rectangular and triangular blocks recursively carved out of the matrix. This redesigned triangular matrix-matrix multiplication implementation achieves up to eightfold acceleration compared to the speed of existing implementations.
"Now, every user of an NVIDIA GPU has a faster solver for a common task in scientific and engineering computing at their disposal," said Keyes.
The solver is due to be integrated into the next scientific software library for NVIDIA GPUs.

Take Norman Mailer's America, Fall 2018.
Novelist, journalist, director, provocateur, pugilist — love him or hate him, Norman Mailer was an integral part of the culture of twentieth-century America.
This section of Studies in Culture will look at the decade of the sixties in America through the eyes of one of its most controversial artists and public intellectuals. We will examine "America" as it grew out of World War II, through the turmoil of the sixties though Mailer's novels, films, journalism, and other cultural texts. This is the country that Mailer loved and hated, the country that made him who he was, and the country that all his efforts tried to make better. This is Norman Mailer's America.
As this section of HUMN 4472 is taught partially online. Please be sure you are aware of the implications before attempting it.

Kid Rigo was initially brought to the attention of The Exceller Fund when we were contacted by a racing fan who was concerned about the fate of this Racing Warrior (with over 80 starts at the time) back in 2009. At that time, we were able to reach out to the current owner, a woman who also worked within the Thoroughbred racing industry. She assured us that the horse was safe. When his career finally ended (with 101 starts), several folks told her to simply get rid of him. She absolutely refused and made all of the necessary arrangements to have him cared for.
Fast Forward to 2013; the owner has now reached out to The Exceller Fund for help. Due to her hectic travel schedule for work, she is very concerned about the attention and care Kid Rigo is receiving when she is away for months at a time. Her decision to turn him over to The Exceller Fund has been a tough one, but in the end it is in the best interest of the horse and that is all she cares about. We are honored to offer Kid Rigo the retirement he has earned and appreciate his owner looking out for him. His breeder, the late Paul Mellon, who always cared deeply for his horses, would be thrilled to learn that this horse will live out his days in safety.

Q: Index Reduction of Differential Algebraic Equations by Hand I dont really understand how to reduce the index of DAEs ?
Does Reducing the index of DAE result in an  ODE ?
How would I reduce the index of the DAE by Hand ?
Say I have :
    $$
    \begin{matrix}
     E & 0 & 0 \\
     0 & M & C' \\
     0 & C & 0 \\
    \end{matrix}
    *
    \begin{bmatrix}
    \dot{y} \\
    \ddot{y} \\
    -\lambda
    \end{bmatrix}
=
    \begin{bmatrix}
    \dot{y} \\
    q-k \\
    -c*\dot{y}-\dot{c}
    \end{bmatrix}
$$
This is an equation for a multibodysystem with constraint. c is a Constraint, C is the Jacobian of it , y the minimal coodinates , M mass matrix and k vector of coriolis force and gyroscopeforce.
Derived from these eq :
$$
M*\ddot{y}+k-C'*\lambda=q \\
c(y,t)=0 \\
\dot{c}= C*\dot{y}+\frac{\partial c}{\partial t}=0 \\
\dot{c}=C*\ddot{y}+ \dot{C}*\dot{y}+\dot{\frac{\partial c}{\partial t}} = 0
$$

A: One intuitive way to understand a DAE is to interpret it as a dynamical system which can be controlled by some input signals, whose output signals have to satisfy some (equational) constraints. For a typical multibody system, the input signals are the forces perpendicular to the constraints, the output signals are the positions of the bodies, and the (equational) constraints on the output signals are fixed distances between the bodies.
The input signals must now control the dynamical system in such a way that the output signals always satisfy the constraints. This is difficult for a multibody system, because the forces only control the rate of change of the velocities, and the velocities only control the rate of change of the positions, while only the positions must satisfy the constraints.
Reducing the index is easy in theory, because if we assume that the positions satisfy the constraints at the current time instance, then we can just replace the constraints on the positions by constraints on the velocities ensuring that the positions will continue to satisfy their constraints. In practice however, we don't want to throw away the constraint on the positions after we determined the constraints on the velocities, but we do have to throw away some of the initial (differential) equations, if we don't want to end with an overdetermined system.
Determining the constraints on the velocities from the constraints on the positions might be tedious in practice, but at least it is straightforward (and canonical) once you understood the principle. The constraint $c(y,t)=0$ implies $\frac{d}{dt}c(y(t),t)=0=\frac{\partial c}{\partial y}*\frac{d}{dt}y+\frac{\partial c}{\partial y}$. This is not an (equational) constraint yet, because $\frac{d}{dt}y$ is not a variable but only the derivative of a variable. But the other differential equations allow us to express $\frac{d}{dt}y$ as a function of the variables, in our case $\frac{d}{dt}y=v$ for $v=\dot{y}$, so we get the equational constraint $0=\frac{\partial c}{\partial y}*v+\frac{\partial c}{\partial y}$ (or rather $0=\frac{\partial c}{\partial y}*\dot{y}+\frac{\partial c}{\partial y}$ if you manage to not get confused by using $\dot{y}$ as a variable instead of the derivative of a variable).
Throwing away some of the initial (differential) equations is less straight forward (or canonical). If we can use a constraint equation like $y_1^2+y_2^2=1$ to determine $y_1$ as a function of the other variables (i.e. $y_1(t)=\sqrt{1-(y_2(t))^2}$ in this case), then we can throw away the differential equation for $y_1$, i.e. a differential equation of the form $\frac{d}{dt}y_1=\dots$. But we might have also decided to throw away the differential equation for $y_2$ instead, because the constraint also allow to determine $y_2$ as a function of the other variables. But no matter how easy it is to throw something away, this can easily destroy some symmetry of the system we didn't want to destroy, or we might be forced to switch which equation we throw away during the numerical simulation and thereby introduce undesired artifacts. So this part makes index reduction really challenging in practice.

A: Let me describe the usual general perspective. It is clearly a matter of computational difficultly (of doing it "by hand" with or without the help of some computer program) whether or not one is able to reduce a DAE to an ODE. There are complications when the non-ODE part has multiple solutions, i.e., it is under-determined or is quite difficult to express explicitly (say in terms of elementary functions, elliptic functions, etc). Other than this, the truth is that the DAE theory is a simple consequence of the ODE theory. Moreover, one can make corresponding observations for a DAE theory for partial differential equations, delay equations, etc.
The DAE theory curiously has reminiscences of the Lyapunov-Schmidt reduction method which may be complicated because of considering infinite-dimensions.
Coming back to your problem. What you must do is solve as explicitly as possible the "non-ODE part", plug it into the ODE part, and then you are back to the ODE theory.


candidates, and interview and select a new artistic director. This is in response to the news that Patricia Barker, the company's artistic director since 2010, has accepted the position of artistic director of Royal New Zealand Ballet.
In order to ensure a seamless transition, Patricia and the Board have expanded Attila Mosolygo's role to director of Grand Rapids Ballet School (GRBS), a role formerly filled by Patricia. Mosolygo, who retired from dancing at GRB in 2013 after 16 years, will oversee the administration, curriculum, and creative vision of GRBS which currently enrolls over 250 ballet students. Mosolygo will also continue as director of GRBS's Junior Company and as a GRB ballet master.
Barker will split her time during the 2017-18 season between GRB and her new role as artistic director for Royal New Zealand Ballet. Accordingly, other organizational changes are being implemented for the upcoming 2017-18 season. Dawnell Dryja, a GRB company dancer since 2002, is being named artistic coordinator, and Nicholas Schultz, Laura McQueen-Schultz, and Steven Houser are being elevated to the position of interim ballet masters in addition to company dancers.
After seven years with the Grand Rapids Ballet, Barker is taking on a new adventure on the other side of the globe.

Former Pacific Northwest Ballet star and current artistic director of Grand Rapids Ballet (GRB), Patricia Barker, will become the Royal New Zealand Ballet (RNZB)'s twelfth artistic director and only the second female director in its 64-year history. She takes over from current RNZB artistic director Francesco Ventriglia on June 19, 2017. Ventriglia will stay on as a choreographer for the company.
Barker says the application process involved her submitting a strategic overview with a sample production plan. She met with RNZB's search committee via video conference calls and spent three days at the company's home in Wellington where, in addition to meeting and talking with the organization's board and staff ─ including fellow American executive director Frances Turner ─ she had a question and answer session with RNZB's dancers.
"It's exciting: they have an excellent reputation, wonderful reviews, and a great spirit and energy in the studio," says Barker.
According to Barker, RNZB was looking for a unique identity for their 36-member company and she feels she can create that for them.
With a 13 million dollar budget and a history of international touring, Barker says she is ready to apply what she has learned in her career at Pacific Northwest Ballet, as a dancewear entrepreneur, and at Grand Rapids Ballet to moving RNZB forward.
Patricia Barker has been at the Grand Rapids ballet for seven years. Image courtesy Grand Rapids Ballet.
With their 2018 season already set, Barker says she will be initially working on programming for 2019 as well as getting to know the dancers and the organization. With that advanced planning in place along with seasonal differences in when RNZB performs, it will allow Barker to also stay on as artistic director at Grand Rapids Ballet during the coming 2017–18 season.
"It's nice because their [New Zealand's] summer is our winter and there will be opposite weeks of work," says Barker. "I can do a lot remotely and be in Grand Rapids for the opening of productions." She also says she still plans on staging a few ballets on the company.
GRB's 2017–18 season, which includes "From Russia With Love," which is a program of highlights from "Sleeping Beauty," "Swan Lake," "Giselle," "Esmeralda," and "Don Quixote;" their annual "The Nutcracker" production re-imagined by "Polar Express" author Chris Van Allsburg; two repertory programs celebrating diversity with world-premiere works by some of today's most influential choreographers; and the world-premiere of choreographer Penny Saunders' Oscar Wilde inspired ballet "The Happy Prince and other Wilde Tales," will now act as a farewell celebration of Barker's seven years with the GRB, taking it from a relatively unknown regional troupe to one with a national presence.
