The 2019 Toyota Prius gains optional all-wheel drive, making America's best-selling hybrid car an even more attractive prospect.
The 2019 toyota prius electric vehicle qualifies for a federal tax credit of up to $7,500, effectively reducing the net base price.
America's best-selling hybrid moves to solidify its position, adding new features to keep it one step ahead of competitors like the Hyundai Ioniq, Kia Niro, Chevy Volt and Honda Insight, not to mention larger hybrid sedans like the Honda Accord and Toyota Camry. Adding to the 2019 Toyota Prius' impressive reputation for safety, reliability and fuel economy is the availability of all-wheel drive (AWD), a first for a hybrid car in this class and one that promises to make the Prius a better year- round companion. Although no longer the fuel-mileage king, the Prius' futuristic design helps it stand out from more traditionally styled hybrids, and with four trim levels from which to choose, there's a Prius to fit just about every taste and budget.
The dependable 2019 Toyota Prius is a boldly styled hybrid offering great value, safety and features. The roomy interior will surprise you, as will the impressive fuel-economy figures. A new all-wheel-drive option makes the Prius a winter must-have.
If you find the Prius' look to be a bit too futuristic, you can find equally capable hybrids with a more traditional design in the Hyundai Ioniq, Chevy Volt or even the larger Toyota Camry. The Prius isn't terribly quick or powerful, nor is it much fun to drive. Apple CarPlay isn't available yet, and Android Auto probably never will be.
For 2019, the Prius gains a low-speed all-wheel-drive option and gets a mild facelift and a revised interior with additional rear-seat USB ports and sun-visor extensions. The old numbered trim designations have been jettisoned in favor of Toyota's traditional naming structure.
Smooth and precise, the 2019 Toyota Prius is comfortable, quiet and easy to drive. It's also agile. It's not a sports car by any stretch of the imagination, but it offers surprisingly sporty handling, which could not be said of previous versions. Body roll in the corners is kept to a minimum, and the steering, although not on par with the Mazda3 or Honda Civic, is light and fairly precise. The ride is agreeable, even on choppy urban boulevards, and it's very happy on the highway, feeling more substantial than its predecessors, which lacked stability especially in windy conditions. There's also a satisfying burst of power off the line, which makes the Prius feel quicker than it is. Its zero-to-60-mph time of about 10 seconds isn't going to thrill, but there's more than enough power when you need it. And the fuel economy is exceptional, which is of course the point. Drive it like Burt Reynolds in Smokey and the Bandit and you'll still average over 45 mpg.
The Prius' AWD-e system employs an electric motor at the rear wheels to deliver traction-enhancing all-wheel drive at speeds under 43 miles per hour. At speeds up to 6 mph, the system is fully engaged, helping with acceleration and traction, after which the Prius reverts to front-drive until wheel slippage brings the AWD back on line.
At Toyota, safety is a priority, which is why unlike its competitors, every Prius regardless of trim level comes standard with Toyota's Safety Sense P technology. The system includes automatic emergency braking with pedestrian detection, adaptive cruise control, automatic high beams plus lane-departure warning and assist.
Toyota's Prius for 2019 gets an interior makeover, with more upscale features like Piano Black trim on the steering wheel and center console, and a reimagined Tesla-like 11.6-inch touch-screen display on the new Limited trim. The seats are wide and supportive, with an impressive amount of legroom both front and rear. The traditional Prius dash concept remains to this day, with the center-mounted instrument cluster placed high up at the windshield's base. The wireless charging pad is now larger, and the heated-seat buttons moved to a position just forward of the cup holders. Faux leather is offered on higher trims and is also used on the steering wheel that is now heated on XLE and Limited trims.
Priuses of the past were considered boring to look at. They weren't unattractive, but they didn't excite either. This time Toyota's design team took a few chances and the exterior design of the 2019 Toyota Prius is anything but uninteresting. No, it probably won't win any beauty contests, but its futuristic lines and avant-garde lighting certainly stand out in a crowd. This Prius has presence. It's larger too, longer, lower and wider than previous models, and more aerodynamic. Its low hoodline doesn't just cheat the wind to improve fuel economy, it also improves visibility for the driver, which helps in tight parking lots.
The feature list for the basic Prius L Eco makes it clear that "basic" does not mean "stripper" for this car: Witness the dual 4.2-inch customizable color information displays, 6.1-inch color touch screen, 6-speaker AM/FM/CD Entune audio, 2.0 USB port, Bluetooth streaming, Siri eyes-free, 15-inch alloy wheels, keyless entry and push-button start, cruise control, tilt/telescope steering column, heated outside mirrors, rearview camera, stability control, traction control and eight airbags. Toyota's Safety Sense P has full-speed dynamic cruise control, capable of bringing the car to a complete stop. The system also includes a pedestrian-detection feature, lane-departure warning and steering assist, which will make small steering corrections for you, and automatic high-beam headlights.
Options vary by trim and most are grouped into packages. Among the more attractive features are a power tilt/slide moonroof with a sliding sunshade, color head-up display, upgraded touch screen, navigation, Entune 10-speaker JBL audio, advanced voice recognition, as well as the standard Prius LE and XLE features, and a good many others. This year a massive 11.6-inch HD Multimedia Display, which is rivaled only by those in more expensive Teslas, now comes standard on the top-of-the-line Prius Limited. All-wheel drive is available but only on the LE and XLE trims.
Powering the 2019 Toyota Prius is Toyota's Hybrid Synergy Drive, which has been adapted to a number of the company's vehicles. It's also been licensed to other carmakers. It consists of a 95-horsepower 1.8-liter 4-cylinder engine, which runs on old-fashioned gasoline, an electric motor and an automatic transmission. Combined output is a respectable 121 horsepower, but it's the powertrain's smooth function and delivery that impress, and of course its industry-leading fuel economy. An all-wheel-drive option pairs this powertrain with an electric motor that powers the rear wheels at speeds up to 43 mph. AWD-e is permanently engaged at speeds up to 6 mph, after which it becomes a part-time system only coming online when it senses the front wheels slipping. The additional electric motor adds seven horsepower and 40 lb-ft of torque to the standard Prius' output. The Prius runs on regular-grade gasoline to keep operating costs low. This is a traditional hybrid; if you're looking for a plug-in hybrid, Toyota offers the Prius Prime.
The 2019 Toyota Prius is available in four trim levels: L Eco, LE, XLE and Limited. The Manufacturer's Suggested Retail Prices (MSRP) range from about $24,700 for the L Eco to over $33,000 for the top Prius Limited. All-wheel drive adds another $1,400 and $1,000 to the LE and XLE's bottom line, respectively. Prius pricing compares favorably with hybrid competitors like the Chevrolet Volt, but costs more than the lesser-equipped, entry-level Hyundai Ioniq and Kia Niro. While Toyotas are some of the top cars in the resale market, the Prius won't fare as well as its stablemates as it ages.

Kalista (grč. , Kallistố) u grčkoj mitologiji bila je kći kralja Arkadije Likona ili je pak bila nimfa.

Etimologija

Kalistino ime dolazi od grčke riječi , kallístê = "najljepša".

Mitologija

Kalista je bila Artemidina sljedbenica i zavjetovala se ostati djevicom. Ali u nju se zaljubio Zeus te su vodili ljubav dok je on bio prerušen u Apolona (za razliku od ove Heziodove, Ovidijeva inačica mita donosi da se Zeus prerušio u samu Artemidu). Kad se kupala s Artemidinim nimfama, otkriveno je da je trudna te ju je boginja pretvorila u medvjeda, a u tom je obličju rodila i svoga sina Arkada. Druga inačica priče govori da ju je Hera pretvorila Kalistu u medvjeda da bi se osvetila zbog muževe prijevare.

Mit govori da ju je njezin sin Arkad gotovo ubio u lovu kopljem, ali Zeus je to spriječio i oboje ih postavio kao zviježđa Veliki medvjed i Mali medvjed na nebu. Druga inačica mita govori da su lovci uhvatili i nju i njezina sina te ih doveli Kalistinu ocu Likonu, a Zeus ih je potom pretvorio u zviježđa.

Heri se to nije svidjelo te je tražila Tetiju da joj pomogne. Tetija ih je proklela da zauvijek kruže nebom i da nikad ne zađu ispod obzora (zato su cirkumpolarni).

Q: Flask Javascript Json Data - Undefined I did have this code working a few years ago and have recently come back to it,  i have a javascript refreshing data on a web page.  Im calling the server using json and receiving back what i think is ok.
My python database code, which seems to work fine.
    cur = db.execute('select sensor_name, temp from cur_temps ORDER BY sensor_name')
    return jsonify(cur.fetchall())

Received Json
[["BoilerRoom",24.94],["Cylinder1",49.94],["Cylinder2",42.38],["Cylinder3",41.88],["Sensor1",85],["SolidFuelFlow",59],["SolidFuelReturn",41.62]]

Im trying to get the number thats associated with Cylinder2 = 42.38
My js code that worked previously is as follows
<script type=text/javascript>
function get_temps() {
    $.getJSON("_status",
            function (data) {

                $('#CylTop').text(data.Cylinder1 + "°")
                $('#CylMid').text(data.Cylinder2 + "°")
                $('#CylBot').text(data.Cylinder3 + "°")
                $('#Solid_flow').text(data.SolidFuelFlow)
                $('#Solid_return').text(data.SolidFuelReturn)
                $('#BRoom').text(data.BoilerRoom);
                console.log(data)
                console.log(data.Cylinder1)
            }

    );

}
setInterval('get_temps()', 5000);
</script>

The console shows the (data) fine in the browser, its when i try and show anything else.  ' console.log(data.Cylinder1) ' that shows undefined.
Im a newbie so im assuming some indexing needs to happen as its a array but im a bit lost.
Any guidance will be greatly appreciated.
Many Thanks
C Dabbs

A: You seem to be accessing the properties in the data as an object. As per the response, it is an array inside an array. So you will have to flatten it before accessing it the way you have it.

function get_temps() {
  $.getJSON("_status",
    function(data) {
      let flattendData = data.reduce(function(acc, item) {
        return Object.assign({}, acc, {
          [item[0]]: item[1]
        });
      }, {});

      $('#CylTop').text(flattendData.Cylinder1 + "°")
      $('#CylMid').text(flattendData.Cylinder2 + "°")
      $('#CylBot').text(flattendData.Cylinder3 + "°")
      $('#Solid_flow').text(flattendData.SolidFuelFlow)
      $('#Solid_return').text(flattendData.SolidFuelReturn)
      $('#BRoom').text(flattendData.BoilerRoom);
      console.log(flattendData)
      console.log(flattendData.Cylinder1)
    }

  );

}

Q: cannot find out why odoo sequence is incrementing twice? I created a model with a sequence field on it:
class AimedPurchaseOrder(models.Model):
    _name = "aimed.purchase.order"

    name = fields.Char('Number', readonly=True, copy=False,
                    default=lambda self:self.env['ir.sequence'].next_by_code('aimed.purchase.order'))

And I added the sequence like this:
<record id="seq_purchase_order" model="ir.sequence">
    <field name="name">Aimed Purchase Order</field>
    <field name="code">aimed.purchase.order</field>
    <field name="prefix">BCV</field>
    <field name="padding">4</field>
    <field name="company_id" eval="False"/>
</record>

The problem is that when I open the form view to create a new record, I get the next value of the sequence that it should be saved, but when I save the record it increments another time and I find records in the tree view with this sequence :
BCV0002, BCV0004, BCV0006, ...
How it that possible? How can I fix it so it saves the default value showed at first time without incrementing again?
Update:

When I remove the readonly=True it works fine, but I can't let this field editable.

A: I'm not fully sure but IIRC you can use force_save="1" since Odoo 11 as attribute on fields in views to tell Odoo to write values for readonly fields.
An example for a readonly field:
<field name="my_readonly_field" readonly="1" force_save="1" />

If on older Odoos (10 and less) there is a community module adding this feature to Odoo which is called web_readonly_bypass and for example can be found here for Odoo 10.


I'll be performing live on my experimental No Input Software system this Sunday, 13 February at a special Valentine's Day gig. Headlining will be Campbell Kneale from New Zealand, best known for his work as Birchville Cat Motel, but now producing sounds as Our Love Will Destroy The World -- appropriate enough given the occasion!
Damien Mullane has organised this "night of Music, Art, Partying and Apocalyptic Love" at Raggle Taggle Space (corner of Sarsfield + Henry) in Limerick, Ireland. Doors at 9pm. Admission 7 Euro (5 for students with ID). BYOB. More info at the Facebook page.
The "no input" mixing desk is a sound mixer with outputs wired to inputs, thus creating feedback loops of various permutations and sonic characteristics. Recently I have been recreating this type of cybernetic system in software, in order to challenge certain myths of digital representation. The pieces are improvised live with no overdubs.
The origins of these techniques can be traced back to 1948 and Louis Barron, who, directly inspired by Norbert Wiener's Cybernetics, built feedback circuits that literally burnt themselves up. By 1972 David Tudor was utilising acoustic feedback between transducers in "Untitled". I believe there's still a lot of sonic space to explore in this realm.
My use of Reaktor to reconfigure a modality most associated with electronics is somewhat ironic. Of course we all expect audio software to produce sounds, so it is hardly a trick to do so! However my instruments are built to model the analogue equivalents closely, with no use of synthesis as such, no samples and no audio inputs.
Two examples of what this might sound like are available on my Listen page through SoundCloud. Check out "Bone-Seeker" and "The Department Of Fallout". The results are chaotic and only partially predictable, so who knows what will happen on the night.
I invite you all to this rare live performance.
Just confirmed: I am on at 9:30pm and times will be sharp as the venue must close at midnight.
Got in a good few hours of rehearsal today. Am glad I get to work in stereo since I've got a few wicked delay combos to play with!

Norway's Andreas Bakkerud embarks on the seventh round of the FIA World Rallycross Championship at Holjes in Sweden this weekend following his strongest performance of the year so far at Hell in Norway three weeks ago.
Last year, at 'The Magic Weekend' in Holjes, Bakkerud claimed his second of three 2017 victories (the others were in Norway and Argentina), but the Hoonigan Racing Division had to fight back after damaging his Ford Focus RS RX's suspension in a qualifying race. Bakkerud started on the front row of the grid in the final next to Sweden's Timmy Hansen, and as Hansen led the field on lap one, Bakkerud took his joker lap.
Hansen was followed by Peugeot-Hansen team mate Sebastien Loeb, Volkswagen RX Sweden's Anton Marklund and EKS's Mattias Ekstrom on the first lap, Ekstrom taking his joker on lap two and returning to the main circuit behind Bakkerud. Marklund passed Loeb at the end of the first lap after the jump but following his joker lap, returned to the main circuit behind team mate Johan Kristoffersson, who had taken his joker on lap one. Kristoffersson later experienced technical problems and was passed by Marklund for fourth place.
Hansen and Loeb took their jokers on the final lap, Bakkerud moving into the lead to claim victory. Hansen experienced a problem after the jump on the final corner and was overtaken by Loeb for second place just before the finish line. Ekstrom retired his car with a problem. Hansen was also involved in last-corner drama at his home event in 2015 too, where he passed Ekstrom to claim victory, but was later penalised for the move and the positions were reversed.
Read the Holjes RX event preview here.


Milos Raonic and Jan-Lennard Struff meet in the first round of the 2017 Wimbledon.
Milos Raonic has just one grass court match under his belt this season, but he brings a 16-6 career record at the Wimbledon. Raonic ha struggled with his return in each of his last two matches, but he did make last years Wimbledon final, and this is his second most successful grand slam. Its no secret that Raonic has one of the top serves in the world, and when he's on, he's one of the tougher players in the world to beat. As long as Raonic is hitting his spots and his serve is on point, he's a threat to make another deep Wimbledon run. Raonic hasn't lost in the first round of a grand slam since the 2011 French Open. Raonic has won six of his last eight matches on grass court.
Jan-Lennard Struff enters this tournament with a 1-2 record on grass and has lost five of his last six matches overall. Struff is coming off a match in Halle in which he won 91 percent of his first serve points, but he had seven double faults and struggled with his return, which is the reason he lost in three sets. If Struff can continue to serve a high percentage without the errors, he has a shot here. Struff hopes to make the second round of a grand slam for the fourth time in his career. Struff is 1-4 in his career during matches at the Wimbledon. Struff has lost five of his last six matches on grass court.
Struff has a chance to make this match interesting if he can get a high number of first serves in play. The problem is Struff has had little to no success in grand slam play and has a weak second serve that a player like Raonic will eat alive.
Raonic wins this match in three competitive sets.

The German Bund Question In Greek
By Jeffrey P. Snider|2015-05-11T14:26:54-04:00May 11th, 2015|Bonds, Economy, Federal Reserve/Monetary Policy, Markets|
With Germany's bond market spooking fixed income all over the world, every rate system has fallen under increasing suspicion. US rates seemed to have bowed to the same ghosts, as the benchmark 10-year treasury rose in yield to an intraday high of around 2.30% last week. That was a sharp increase in only a few days, a trading week, that seemed to be in at least some sympathy to Germany.
While we can't possibly know yet if there has been a paradigm shift in UST's, there are a few hints that Germany is Germany and UST is operating under its own constraints. For one, the scales of both moves were not really similar at all. While there is this more "benign" "dollar" environment more recently that might unite trading pressures, there are, again, indications that may be shifting and UST's for liquidity may be back in play.
The move in UST vs. bunds is absolutely minor and does not really stand out much from the trading range of the past eight or nine months. In fact, that recent peak last week is very reminiscent of the rise in yields to March 6. That week was notable for its heavy corporate issuance, an intermittent presence which has the effect of taking away dealer liquidity. Last week also contained a heavy corporate calendar, meaning that dealer balance sheet constraints are amplified as to the already-low liquidity environment.
So if there was some selling pressure in UST in sympathy with Germany's bond realignment, then there was a relatively atrocious liquidity environment with which to absorb that uptick in selling (also very similar to the trading into March 6). I think that is the important point about the state of liquidity in UST and overall, as what used to be a minor depletion in the state of dealer capacity has transformed into a massive powder keg (in either direction). Since the end of the rate-lock period, UST rates have come back down, and at one point Friday morning the 10-year was trading all the way to 2.10%.
Rates have come back up over Friday and so far today (touching 2.20%), volatility that more than suggests very unstable "markets."
At least as far as the banking side there has been renewed buying interest (through the end of April) which probably has had the effect of keeping the rate "spike" within that prior range. Even with that buying factor, it is clear that liquidity is still depressively low and that is driving all this enormous volatility, a fact obvious on both sides of the Atlantic.
The 30-year bund, for example had fallen to almost 40 bps before shooting up to 1.20% in a matter of a couple of weeks. Whatever the reason for this initial selling trigger (and there is no shortage of candidates) what is lacking is the liquidity with which to contain it more orderly. I think that is the great worry that is unsettling so many bond markets, that if "something" were to occur in one direction or the other there is not much of a systemic impulse to maintain order and containment. Such unchained volatility is further anathema to further liquidity containment.
QE has always brought what seems to be a counterintuitive nature, as the level of "reserves" in any system that tries it will rise but that those "reserves" aren't the same as functioning liquidity. As it is, the German repo market is as its US$ counterpart, a shell of its former self. And while the talk more recently has been about QE actually working and thus "inflation" working its way back into these yield expectations, the sharp rise in yields in Europe aren't the gentle guideslope usually reserved for such slower building in changing perception. If anything, the sharp selloff in Germany bonds has the fingerprints of Greece.
The European parties are no closer to a solution to Greece's problems now than they were three years ago. Despite a double dose of default, the country is no closer to the economic restoration that was promised by so much fiscal recalculation.
In forecasts published on Tuesday, the European Commission predicted the Greek economy would grow 0.5 percent this year, down from the 2.5 percent estimated in February. Adding to the tension, the Financial Times reported that the International Monetary Fund warned it may cut off support to Greece.
"Greek economic conditions are deteriorating," said Frederik Ducrozet, an economist at Credit Agricole SA's corporate and investment banking unit in Paris. "It's negative in terms of the fiscal revenues and the backdrop for the negotiations. But it also provides Greece with some bargaining power when they negotiate the primary surplus for this year and next."
That was last week as the reality of the missed IMF payment tomorrow is weighed. That was a probability that gained a lot of attention in early April. Peripheral bond yields, once the most "no brainer" trade on the entire face of the planet suddenly began to rise. Spanish bonds, for example, peaked on March 12 and then gained a burst of selling on April 7 when Greece was again at the forefront negotiating how it would negotiate.
To my eye, it almost appears as if peripheral yields caught up in the rerun of Greece's impending problems are pulling Germany and the rest up with them. That makes some sense in light of the spread trade that has predominated since Mario Draghi first promised to "do whatever it takes." A compression in spreads of the periphery to Germany has been almost fully guaranteed, so to see a rather stark reversal in one half of that trade certainly pressured both sides. With the ESP-GER spread (shown above) surging toward April 21 it would seem that eventually something had to give.
Greece's Finance Minister Yanis Varoufakis said on Sunday that if Athens were to leave the euro zone, there would be an inevitable contagion effect.
German 10-year Bund yields fell 1 basis point to 0.07 percent, having fallen as low as 0.05 percent on Friday. They have fallen 8 basis points in the past week.
"The momentum of the decline in yields in the last week points technically and psychologically to an impending attack on the zero percent level by the 10-year Bund yield," said Norbert Wuthe, senior analyst at Bayersiche Landesbank.
Greek 10-year yields held close to their highest level since late 2012 at 13.20 percent, while two-year yields rose 92 bps to 28.27 percent.
Again, the periphery had already started moving in tandem with Greek debt and that German bunds rather than "an impending attack on the zero percent level" suddenly reversed as the rest of Europe's sovereigns were sold and sold hard from there on.
I think that puts both parts of the trends to question; we know that there has been "herding" in German bunds for years, and on the other European sovereigns, and that a very low and troubling liquidity environment would entertain the "herd turning." I don't think there is very much doubt about that, but there hasn't really been much of a compelling explanation provided as to "why" the herd suddenly turned. Again, I don't think "inflation" and QE "success" would generate such violent selling, though that may just be the low liquidity environment.
From May 5:
Yields on Italian 10-year debt climbed as much as 30 basis points to 1.84 percent, a level last seen on Jan. 12. The 30-year yield surged 35 basis points to 2.90 percent. Trading volume in the first Italian bond future contract rose to the highest since March 18.
Germany's 10-year yield increased for a sixth-straight day, adding six basis points to 0.52 percent. Borrowing costs are climbing even as the European Central Bank sticks with purchases of 60 billion euros of the region's debt a month to revive the economy. The quantitative-easing plan sent the yield to a record-low 0.049 percent as recently as April 17.
"It is quite strange that German bund yields are rising so much despite the risk-off sentiment on the back of Greece's development," said Gianluca Ziglio, a fixed-income strategist at Sunrise Brokers LLP in London.
Instead, the behavior in yields in Germany is now just as "risk-off", very much like the behavior in yields in Spain, Italy and Portugal (the resurrection of the PIIGS) which to me suggests Greece is finally, after being ignored for months on end, getting its "due." In other words, the peripheral bonds began to selloff and then Germany's joined them in a manner unlike what we saw of 2011 and 2012. It's not that parts of Europe may be risky, reflected by government yields that are far too artificial, it may be dawning that all of Europe is that way.
The fixed income world, tied together through the eurodollar system, makes that herd repositioning impossible to ignore. With several Greek events coming up, it will be interesting to see if that theory is verified or refuted by the world's nervous and malfunctioning bond markets.

California's Proposed Flavored Tobacco Ban Offers Hookah a Go
By Micah Williams Last updated Nov 3, 2022
LOS ANGELES — In 2019, local business owners began gathering regularly at Arnie Abramyan's hookah lounge on the outskirts of Los Angeles to fight a proposed statewide prohibition on the sale of flavored tobacco.
From the heavily Armenian neighborhood of Tujunga in the foothills of the San Gabriel Mountains, Abramyan and other hookah shop and cafe owners began spreading the word that the ban, prompted by a burgeoning epidemic of e-cigarette use among teens, could put them out of business and extinguish a beloved social ritual that many feel is part of their heritage.
"We were going to be collateral damage," said Abramyan, now president of the National Hookah Community Association.
As their movement grew, the business owners hired a lobbyist and traveled to Sacramento to meet with lawmakers. They posted YouTube videos on "the history and centuries-old tradition" of smoking the water pipes popular in the Middle East. Their work paid off: State lawmakers passed the ban in August 2020, which outlawed the sale of flavored tobacco, including menthol cigarettes — but exempted premium cigars, loose pipe tobacco, and the "flavored shisha tobacco product" used in hookah pipes.
It never went into effect. Big Tobacco quickly launched a referendum drive and gathered enough signatures to bring the issue to voters. This month, Californians will decide — via Proposition 31 — whether to uphold or block the law, which would make it illegal for brick-and-mortar retailers to sell flavored cigarettes, e-cigarettes, and other flavored tobacco products. Sales of gums or gummies that contain nicotine and are not approved by the FDA would also be prohibited.
If the law is upheld — recent polling indicates that a majority of likely voters support it — California would become the second state to rid stores of both flavored vapes and menthol cigarettes, which have helped hook millions of Black and Latino smokers since tobacco companies began marketing them in inner-city neighborhoods half a century ago.
The question of why California has granted hookah smokers an exception while banning menthol cigarettes, the choice of 85% of African American smokers, has sparked a debate about which tobacco products — if any — merit protection. Until recently, efforts to outlaw menthols had failed in the face of aggressive tactics by tobacco companies, which have staved off billions in losses by equating such bans with racism and the war on drugs.
Anti-tobacco groups warn that this strategy has become a model for fending off government interference. They decry the hookah exemption as the latest example of business successfully using identity politics to keep profiting from a deadly product.
"Hookah has been given a pass for no scientific reason," said Carol McGruder, co-founder of the African American Tobacco Control Leadership Council. McGruder, who has spent years waging war against tobacco companies for their "predatory targeting" of Black communities with menthol cigarettes, said hookah smoking has become increasingly trendy among Black youths.
Many young people mistakenly believe that hookah smoking is less harmful than other forms of smoking, but experts say tobacco smoked through water pipes is just as addictive as cigarette tobacco and contains similar cancer-causing tar, nicotine, and heavy metals.
"They bring out a beautiful antique hookah pipe and they say that hookah is all about family and community," McGruder said. "But it's all about money."
Big Tobacco itself is assailing the hookah exemption, saying it proves that the law discriminates against Black and Latino smokers by banning menthol flavors, while giving "special treatment to the rich," as an ad campaign paid for by the industry argues.
"Prop. 31 will increase crime and expand illegal markets, cut revenue for critical services and could backfire on the very communities its proponents say they want to help," said Beth Miller, a spokesperson for the "No on Prop 31" campaign.
More than 360 municipalities, clustered primarily in California and Massachusetts, have restricted the sale of flavored tobacco products, including e-cigarette pods in kid-friendly flavors — strawberry, chocolate milk, and pink punch — which health officials say have provided a gateway to teenage smoking. Roughly half of the ordinances restrict menthol, while fewer than 20 — nearly all of them in California — exempt hookah tobacco and/or hookah bars.
In 2021, 80% of high school students and nearly 75% of middle school students who had used a tobacco product in the previous 30 days reported using flavored tobacco, the Centers for Disease Control and Prevention reported. In 2019 and 2020, an outbreak of vaping-related lung disease, known as EVALI, killed 68 people.
The vaping epidemic has given anti-smoking activists an opening to lobby against menthol cigarettes. Invented in the 1920s, their cool, minty flavor helped new smokers adjust to them more easily than non-flavored cigarettes, and the industry marketed them as a healthier option. In the 1960s, tobacco companies turned to the Black community, handing out free samples to hip, young "communicators" in barbershops and bars. Menthol cigarettes account for more than a third of the $80 billion U.S. cigarette market.
Reynolds American, the country's largest maker of menthol cigarettes, including Newport, has battled menthol bans by giving money to the Rev. Al Sharpton's National Action Network and other civil rights groups. When the New York City Council proposed a menthol cigarette ban in 2019, Sharpton cited the case of Eric Garner, a Black man who died in police custody in 2014 after he was stopped for allegedly selling single, untaxed cigarettes on the street.
But the success of these efforts came at a devastating price, public health experts say. African American men have the highest rate of new lung cancer cases in America, according to the CDC.
Earlier this year, the FDA announced a plan to ban sales of menthol-flavored cigarettes, a long-awaited move hailed by health officials and some Black leaders, even as they braced themselves for a protracted legal battle with the tobacco industry that could delay the ban for several years.
For years, anti-smoking activists have been focused on menthol, said Valerie Yerger, an associate professor of health policy at the University of California-San Francisco. "Nobody was focused on hookah," she said.
But water-pipe use among young people has been on the rise in recent decades.
At Hookah battles across the United States and Europe, contestants compete to build the most elaborate water pipe, often to a hip-hop soundtrack. Elaborate water pipes, with their billowing puffs of smoke, are often prominently featured in rap videos.
"It's just another way the industry has found to keep our young people addicted to these products," Yerger said.
Hookah purveyors argue that blanket prohibitions endanger small-business owners, many of them immigrants, and threaten to erase a "rich cultural heritage" by effectively outlawing hookah pipes, which are often part of gatherings and celebrations for Arabs, Armenians, Persians, and others hailing from the Middle East. They reject the claim that their fight is only about money.
"Hookah lounges are a hallmark of community," said Rima Khoury, general counsel for Fumari, a San Diego-based hookah tobacco company.
For Abramyan, smoking a hookah was an after-dinner, adult ritual his Iranian-born parents brought with them when they immigrated to America in the 1980s. The ornate water pipes are often several feet tall and take at least 20 minutes to set up.
"This is not something kids are smoking in the bathrooms at school," he said. "We don't want our kids to smoke, but why shouldn't my grandpa be able to smoke his hookah in his backyard?"
Bible study groups and the local Rotary Club chapter regularly meet at his Tujunga hookah lounge, Garden on Foothill, which features outdoor gazebos for families and groups. "For Muslims who don't drink alcohol, or people who don't like to go to strip clubs, this is a safe space," he said.
The shop he runs a few blocks away, Munchies Mart, sells handmade hookah pipes and tobacco in flavors such as Strawberry Lemonade, Orange Pop, and Agua Fresca, a far cry from the apple-soaked tobacco he remembers his Persian grandmother mixing in her kitchen.
Using cultural practices to argue for public policy exemptions is nothing new, said Arnab Mukherjea, an associate professor of public health at California State University-East Bay.
But he said that communities often suffer when corporate interests "use cultural identity to market a product for mass consumption."
"You go to any college town," he said, "and the hookah bars are filled not with practicing Muslims, but with college-age kids who are going there to socialize, consuming flavors in bubble gum and cotton candy."

Local Structure Analysis in Simulated Materials via Voronoi Topology
Emanuel A. Lazar
Laboratory for Research on the Structure of Matter
School of Engineering and Applied Science
Describing how atoms are arranged in real and simulated materials is a very natural problem that arises in numerous computational materials science applications. However, aside from perfect crystals, insightful yet tractable descriptions of local arrangements of atoms can be tricky to develop. We consider several conventional order-parameter methods for describing local structure and highlight their theoretical and practical limitations. We then introduce a topological approach more naturally suited for structure analysis and highlight its versatility and robustness. In particular, the Voronoi tessellation method can aid in the study of materials at high temperatures, close to melting, without uncontrolled modification of raw data. Applications to the study of grain boundary evolution and melting will be briefly presented.

Embedding Context in Intelligent User Interfaces Using Data Analytics
Dieter Pfoser, Associate Professor
Department of Geography and Geoinformatics
Making sense of user-generated Web content such as social media data, blogs, or even Wikipedia entries poses interesting research challenge considering its lack of structure, amount, and associated noise. This work introduces a range of online content summaries for such unstructured data. Besides the typical spatial, temporal and thematic summaries, we introduce two additional views. Geoevents are emerging events that are limited in spatial scope hashtags and that are detected automatically by comparing their spatial distribution to a global topic search.
Links-of-Interests (LOIs) are connection summaries between geographic locations, people and concepts. These content summaries are available as part of the functionality of a Web-based tool that allows for the interactive visualization, querying and exploration of such unstructured data. This talk will discuss research results and demo the capabilities of the visualization prototype.

Scientific Data Mining and Its Applications in Tropical Cyclone Research
Ruixin Yang, Associate Professor
In this talk I will give an overview of of scientific data mining (SDM) followed by a few examples of SDM applications to the analysis of tropical cyclones (TCs), focusing on their intensity changes. Because rapidly intensifying (RI) tropical cyclones are the major error sources in TC intensity forecasting, association rules facilitate the RI process by mining for sets of conditions that have strong interactions with rapidly intensifying TCs. The technique of association rules explores associations among multiple conditions in a simple manner identifying a predictor set with fewer factors but improved RI probabilities. Furthermore, in searching the "optimal" RI condition combinations, a peculiar condition combination was identified that gives a very high RI probability. Such combination can be considered as a sufficient condition for RI that almost guarantees that a RI will take place. Applications of classification techniques to the intensity forecasting will also be discussed. Several drawbacks and future directions for SDM with the TC intensity change problem will be discussed at the end of the talk.
COLLOQUIUM OF THE COMPUTATIONAL MATERIALS SCIENCE CENTER AND THE DEPARTMENT OF COMPUTATIONAL AND DATA SCIENCES – Robust Estimation of Value-at-Risk for Quantitative Risk Management: Applications to Climatology, Insurance, Accidents and Financial Analysis – Sabyasachi Guharay @ Exploratory Hall, Room 3301, Fairfax Campus
Nov 7 @ 4:30 pm – 5:45 pm
Robust Estimation of Value-at-Risk for Quantitative Risk Management: Applications to Climatology, Insurance, Accidents and Financial Analysis
Sabyasachi Guharay
Establishing robust quantitative metrics which allow decision makers to determine the amount of risk in a system with extreme loss events is a problem of interest in many scientific fields. One of the fundamental metrics which is universally accepted in all fields of risk management is the quantity known as Value-at-Risk (VaR). A subfield of risk management, modern Operational Risk Management (ORM), closely investigates methodologies on robustly estimating VaR, "Robust Estimation of VaR." Currently, academic researchers and industry practitioners are actively looking at ways to make this estimate more statistically robust and accurate with minimal assumption requirements.
In this talk I will present two new quantitative approaches for estimating VaR that are agnostic regarding the relationship between frequency and severity: (1) Data Partition of Frequency and Severity (DPFS) using K-means to estimate VaR; (2) Distribution based partitioning (DBP) of frequency and severity using copulas. Verification is conducted on five simulated scenario datasets while validation is conducted on five publicly available datasets from four different domains: –US Financial Indices data of Standard & Poor's 500 and Dow Jones Industrial Average; –Chemical Loss spills as tracked by the US National Coast Guard; –Australian automobile accidents; –US hurricane data. It is observed that previous VaR calculations inaccurately estimate the VaR for 80% of the cases in simulated data and 60% of the cases in real-world data studies while new methodologies attains accurate VaR estimates which are within the 95% confidence interval bounds for both simulated and real-world data.
COLLOQUIUM OF THE COMPUTATIONAL MATERIALS SCIENCE CENTER AND THE DEPARTMENT OF COMPUTATIONAL AND DATA SCIENCES – Using Coarse-Grained Models to Access Expanded Length and Time Scales for Nanoscience Applications – K. Michael Salerno, Jr. @ Exploratory Hall, Room 3301, Fairfax Campus
Using Coarse-Grained Models to Access Expanded Length and Time Scales for Nanoscience Applications
K. Michael Salerno, Jr.
Center for Computational Materials Science
Polymers and other soft materials have an important role as a coating for nanoscale building blocks like metallic nanoparticles (NPs) and nanorods. This coating mediates interactions between these building blocks and their environment. Atomistic molecular dynamics (MD) simulations are ideal for examining the role of chemistry and atomic interactions at the sub-nanometer scale, for example in the interactions between a NP and a solvent, or between pairs of NPs. Unfortunately, atomistic MD simulations are limited to lengths of order 50 nm and times of order 50 ns. The time scale limitation precludes modeling nanoscale self-assembly, and limits dynamic simulations to extremely high rates of deformation or thermalforcing. These simulations are also limited to sizes that represent a small number of NPs, making it impossible to model large assembled structures.
Faced with these limitations, we have developed coarse-grained (CG) models of polyethylene, a simple polymer used to coat NPs and nanorods. These models have enabled simulations of bulk polymer melts that overcome the limits of atomistic MD by providing a computational speedup of greater than 104 while retaining fundamental details at the sub-nanometer scale. These details produce the viscoelastic properties and semi-crystalline behavior that are intrinsic to polyethylene and that are missed by generic CG models. When applied to a NP coating the CG models capture the coating morphology, indicating the value of using these CG models in nanoscale applications.

Topological Quantification of Microstructures
Tom Wanner
Department of Mathematical Sciences
November 21, 2016, 4:30 p.m.
Many applied processes generate complex microstructures or patterns which are hard to quantify due to the lack of any underlying regular structure. These patterns may evolve with time or include some element of stochasticity. The resulting variations in the detail structure frequently force one to concentrate on rougher geometric features. From a mathematical point of view, several notions from algebraic topology suggest themselves as natural quantification tools in such a setting. In this talk I will describe some of these tools, in particular homology and persistent homology, and how they can be efficiently computed using open source software. I will also present some applications motivated by materials science problems.

Leveling the Playing Field: Information Asymmetry in the Used Vehicle Buying Process
Monday, January 29, 4:30-5:45
In 1970, Economist and Nobel Prize winner (2001) George Akerlof published a study: "The Market for "Lemons": Quality Uncertainty and the Market Mechanism" (The Quarterly Journal of Economics, Vol. 84, No. 3. (Aug., 1970), pp. 488-500). In the study, Akerlof attempts to show where, in a market where as seller of a product has more data/information than the buyer of the product, about the product's quality, will potentially result in "an adverse selection of low-quality products." In no place is Akerlof's theory more represented than in the used vehicle market, where buyers and sellers don't always have the same information about a vehicle's quality, potentially resulting in low-quality cars being bought and sold. In 1986, CARFAX sought to begin to "level the playing field" between buyers and sellers of used vehicles by collecting, analyzing and making relevant data/information available in the marketplace to both buyers and sellers.
What data does CARFAX collect?
Why this data vs other data?

COLLOQUIUM ON COMPUTATIONAL SCIENCES AND INFORMATICS – Why an open mind on open data can transform our collective intelligence – Batarseh @ EXPLORATORY HALL, ROOM 3301

Why an open mind on open data can transform our collective intelligence
Monday, February 5, 4:30-5:45
Abstract: In 1822, the founding father James Madison said: "A popular government, without popular information, or the means of acquiring it, is but a prologue to a farce or a tragedy, or perhaps both". Recent technological waves have evidently served Madison's vision of government transparency. The latest advancements in Artificial Intelligence (AI), Data Science, and Machine Learning can make federal data openness a low hanging fruit. Moreover, the big data and open government initiatives (signed in 2012 and 2013) are major enablers for transforming government into a new era of intelligent and data-driven policy making. However, to be able to use data in reforming the political discussion, public federal data needs to devise the promised openness.
Besides benefiting government, Open Data benefits many other domains and applications of data science, such as healthcare, finance, and academia. For example, Open Data could lead to a general openness in science (i.e. Open Science), clearer experimental research, and begin reshaping the human knowledge in general. These topics and other facets will be discussed in this talk.

Monday, February 12, 4:30-5:45
Abstract: Modernization of nearly all the technology that underlies the provision of rail and bus transit service over the past 30 years has resulted in a vast amount of data that until recently has been more or less neglected. Meanwhile, challenges that face rail and bus transit systems continue to mount, from maintaining a state of good repair to capturing and keeping riders in the age of Uber/Lyft and bike share. The key to providing safe, convenient, affordable, and reliable transit service into the next century lies in the hands of data scientists and policy analysts. This talk will review the different data-generating technologies and the types of data they create, followed by an exploration of the pressing issues faced by transit agencies and the questions begging for answers.

Sports Betting is on its way to a state near you…..well, legal sports betting. The black market for wagering on sports in the USA looks to be falling by the waist side. New Jersey becomes the 3rd state outside of Nevada to offer a full feature sports betting platform. After years of reigning supreme in the daily fantasy sports industry, DraftKings recently opened their own sportsbook back in early August 2018. At the time it was the first full-service online and mobile sports betting platform in the legal New Jersey sports betting marketplace.
All of that being said, DraftKings does have one thing that almost all of these other books don't have: brand recognition. Many "average joe" public bettors will feel comfortable in making a deposit at DraftKings sportsbook.
Breaking news hit on Wednesday that DraftKings sports betting app had gone live in New Jersey. The state requires a 5 day testing period in which only a max of 500 users are allowed on the app in order for proper testing. The news broke on Twitter that an invite only process had begun for the DraftKings sportsbook launch in New Jersey.
Subsequently, some screen-shots have begun to appear online, along with some criticism over the vig or juice listed for wager within the DraftKings betting app. FanDuel has also been hit hard with daily screen-shots on Twitter pointing out their high than normal vig.
Additionally, as we've also mentioned, the number of different betting options do help DraftKings separate themselves from the competition. NFL player prop bet boost wagers, betting on player fantasy points and just 2 examples.
The DK Sportsbook cash out feature is also extremely innovative. Basically, a player can cash their bet out at any time during a live game. However, what they get back or ROI will reflect the live betting odds at the given time.
The DK management team has been preparing for more than a year to get its sports betting platform for mobile off the ground. They contine working with state regulators to apply for operating licenses in states that have passed laws authorizing sports betting.
With roughly 10 million customers in their DFS player database, DraftKings is primed for a state by state legalized sports betting marketing approach.
What about DraftKings top rival in the fantasy sports space, FanDuel? Well, it looks like U.K. gambling powerhouse Paddy Power will be acquiring FanDuel in order to help build out their already robust gambling audience potential in the United States.
Paddy Power confirmed it was already in talks with FanDuel "to create a combined business to target the prospective US sports betting market".
If a deal goes ahead, it is likely to be worth considerably more than the $48m that Paddy Power paid for a much smaller DFS site called "DRAFT" last year. FanDuel would bring over 6 million registered users or "gamblers", into the newly merged company. DRAFT has previously hired quite a few FanDuel employees who were let go by the DFS giant earlier this year.
With all the positive aspects we have covered in this review of DraftKings Sportsbook, their customer support is the only area that may need some attention. Now, to be fair, we are sure DK will be focusing on customer support as sports betting legislation is approved in more states.
Currently, there is a help menu, but trying to contact an actual person is a little more difficult. Players either leave a message and hope for the best or fill out a call-back form. While customer service is technically available 24/7, it doesn't reflect the overall response time.
We may be a few months away from training camp, but DraftKings Sportsbook has us ready for the 2019 NFL betting season with the release of over/under win totals for each NFL team. The Super Bowl Champion New England Patriots win total for 2019 checks in at 11 wins, which is the highest total on the board with the KC Chiefs. The New Orleans Saints are close behind with 10.5 wins as their over-under total at DraftKings Sportsbook.
On the other end of the spectrum, the Miami Dolphins over-under win total is set at just 4.5 wins for the 2019 regular season. The Bengals and Arizona Cardinals round out the top 3 lowest win totals at just 5 wins. With the NFL Draft Betting just around the corner, we should expect some movement in win totals again in May 2019.
Looking to use a familiar face to New Jersey sports bettors, DraftKings has just launched a new TV ad campaign with Charles Barkley. Playing in Philadelphia during the 1980's and 90's, along with publicly admitting to being a large sports bettor over the years. Barkley looks to be a wise choice for a regional coverage in NJ,DE,PA.

The sign-up bonus at DraftKings is one of the best and most potentially most lucrative for Sportsbooks in New Jersey. The days of waiting for drip bonuses and earn-outs are long gone at DraftKings. The new player bonus is an INSTANT offering available via a free bet ticket at DraftKings. Some other promotions include opting out of bets at a certain time to cut your losses and profit boost promotions. When you consider the instant new player bonus, plus the creative sports betting promotions at DraftKings, it is easy to see why they are the top promo code bonus option for sports bettors in NJ.
As the first online sportsbook to launch in NJ, DraftKings is now competing with the largest sportsbook brands in the world, let alone the USA. The likes of William Hill, MGM, Caesars, and BetFair (FanDuel) will all battle for sports betting revenue in NJ and more states in the future here in the United States.
DraftKings brings a massive following and brand recognition from their DFS user-base. The $200 instant bet bonus quickly lowers any hurdle for new sports bettors to join DraftKing sportsbook.
A deposit based bonus option would be a good addition.
Free Sports betting content similar to what is offered for DFS should be available.

An Organic & Small Family Farm.
I read an excellent book by Daniel Lapin over the weekend. He says there are ten principles that tips the scales in our financial approach significantly toward prosperity.
Believe in the dignity and morality of business. Making money is much harder if, deep down, you suspect it to be a morally reprehensible activity.
Extend the network of your connectedness to many people. Befriend many people who are a rung or two above and below your financial level, then find ways to help them achieve their desires. You will have discovered the secret of Partnership Power.
Get to know yourself. To change the way others see you, first you have to learn to see yourself as others see you.
Do not pursue perfection. Neither neglect the imperfect nor expend yourself on futile pursuit of perfection, while failing to make the most of less perfect circumstances.
Lead consistently and constantly. Learning to lead is important, but it may not be what you think it is. Leadership is not a noun, it is a verb. It is not an identity, it is an action. Don't try to become a leader, just do it. Just lead.
Constantly change the changeable while steadfastly clinging to the unchangeable. Convert change from enemy to ally by understanding when to enjoy the exhilaration of change and when to fight it an steadfastly defend the unchangeable.
Learn to foretell the future. No one can see the future...that is a prophet. Wisdom is seeing tomorrow's consequences of today's events.
Know your money. Your money is a quantifiable analog for your life force...the aggregate of your time, experience, persistence and relationships.
Act rich: give away 10 percent of your after-tax income. Through the mystical alchemy of money, giving to charity jump-starts wealth creation.
Never retire. Integrate your vocation and your identity by thinking of life as a journey rather than a destination.
Got any questions that maybe you don't want commented on a post or that you need answered immediately?

Retailers worldwide are rapidly introducing innovative technology and solutions into their brick and mortar stores as well as implementing new online operations to improve customer experience. Digital and physical shopping experiences can no longer be viewed as separate entities.
Finnish retail tech companies are leading the field in this transformation, offering a great variety of innovative solutions to improve retail performance in key areas such as sales, marketing, shopping experience, consumer insights and competitor intelligence. Finnish solutions also enable personalized marketing actions, promotions and automated processes.
Finland is a country abundantly blessed with mobile technology, and the Finns consume more mobile data per capita than any other nation. Consequently, Finnish consumers are very mobile reliant and the number of mobile shoppers only continues to grow in Finland.

TIP! Try out many exercises, and choose your favorites to build a routine that you can stick to. If you find something you enjoy, you might actually anticipate your workout positively.
Whether you're just starting out with a fitness routine or you are an experienced athlete, you can always benefit from increasing your knowledge about fitness. When you know how your body can work and what you need to do, you can make all the changes you need. You'll get much better results when you follow our advice.
TIP! If you develop a plan and set goals you can stay on top of your fitness journey. Setting goals shifts your focus from worrying about the difficulty of an obstacle, to discovering how to overcome it.
Make sure your workouts include a variety of different exercises. This will keep you focused and motivated so you keep coming back for more every day. Also, once your muscles become acclimated to a particular set of exercises, you stop getting as much benefit from that workout.
Make sure that you have the appropriate shoes when you exercise. Protect your legs, feet and back from injury by choosing footwear designed for the activity you are engaged in. Also, you will experience significant discomfort that may prevent you from continuing your routines.
TIP! Try to be creative when thinking up a fitness plan. There are more options than just going to a gym available to someone looking for a good way to exercise.
When you are weight lifting, squeeze your buttocks each time you lift the weights up. Your bottom receives an enhanced workout and your chance of injury is greatly reduced because you are better positioned. That position greatly stabilizes your spine.
TIP! When you are watching television, you can still exercise to continue your momentum in losing weight. You can walk around your living room during a commercial or do an exercise when there is a break in the action.
TIP! Do you want to increase the intensity of your workout? Stretching is great for your body and can improve your strength by 20% or more. You should take some time inbetween sets to stretch.
If you want to exercise do not think of it in this way, have fun with it. Just by calling it either of those names, you may be making yourself less motivated to exercise. Instead, call it what it is. If you are walking, say you are walking.
Accelerate weight loss by increasing the density of your workouts. Completing many exercises in a short amount of time will help you get into shape faster. Shorten breaks between intervals and sets in order to increase the density of your workouts. You'll soon see improved results if you do this.
TIP! If you are going to workout, try to avoid calling it exercise or working out. If you call it by these things, you are more than likely not going to be as motivated.
Do not work out if you are ill. When you are afflicted with illness, your body attempts to use all of its resources in order to heal itself. It's unlikely that you will add muscle to your frame or have the stamina for a workout while you're under the weather. So, halt your workouts until you have recovered. Also, you will want to eat great and get extra sleep.
TIP! Divide your run into parts: A, B, and C. At the beginning of a run, start out slow, and as you go farther, you can gradually increase your pace.
Dips can improve your fitness quickly. They work three areas of the body: the shoulders, triceps and chest. They can be completed in a variety of ways. Try positioning two benches near each other so that you can do dips in between them. You can always add weight for every dip.
TIP! Never wrap your thumb around workout bars. It is much better to keep your thumb next to your index finger.
If you are trying to build up the muscles in your calves , try donkey calf raises. These calf raises can be effective for building up those calf muscles. You have to have a partner sit down on your back side, and simply raise up your calves.
TIP! Prior to embarking on a weight lifting regimen with the goal of improving your arms, know exactly what you plan to achieve. If you want to build more muscle, lift heavier weights to increase the level of intensity on your body.
Count backwards. Start from the top, and count down instead of counting to the amount of reps you are doing. This will make you strive to complete your exercise set. It is also very motivating.
TIP! You will want to take your time when you start an exercise program. Make sure that your technique is solid and that you are not straining your muscles.
Taking your dog for a walk can be a great way to start exercising. Dogs love to walk, so they won't get bored with a walk every day. Ease into it. Begin with a quick walk around the block and expand from there by walking a little further each day. This is a great perk of owning a dog.
TIP! If you find yourself skipping days in your fitness program, enlisting the help of a friend can put you back on track. Working out with a partner may help you become more interested and motivated.
Whatever your fitness level may be, using these tips will make your fitness routine better. If you learn about staying fit, you will be able to achieve the best results while working out. Keep these tips in mind to get in shape quickly and easily.

Postgres Query Plan Visualization - Andrew W
http://tatiyants.com/postgres-query-plan-visualization/
Ever wondered what those weird numbers are when you're trying work out why your SQL query performance is so bad and you do "EXPLAIN SELECT …". Well, wonder no more because Alex Tatiyants has written a Postgres EXPLAIN Visualizer (PEV) that will take the output from the EXPLAIN command and turn it into a human legible diagram so that mere database mortals can see what's happening to their query.
Thinking about technical debt differently - Murray S
http://laughingmeme.org/2016/01/10/towards-an-understanding-of-technical-debt/
We talk about technical debt a lot, but there's no clear understanding across our industry of what we mean. We all know it's something bad, but we can mean lots of differnt things that require different approaches to mitigate or remove. This article goes into what we really mean when we use those words and explores the different meanings. The closing paragraph has a really good point too, about not getting too hung up on the choices we make right now:
All code is technical debt. All code is, to varying degrees, an incorrect bet on what the future will look like.
Rails Dynamic Render to RCE (CVE-2016-0752) - Andrew W
https://nvisium.com/blog/2016/01/26/rails-dynamic-render-to-rce-cve-2016-0752/
Rails 4.2.5.1, 4.1.14.1 and 3.2.22.1 were released this week to fix a number of vulnerabilities but CVE-2016-0752 was probably the most serious one, but hopefully it's the least likely to occur in the wild since it requires the developer to be passing the parameters hash directly into the render call. Moral of the story is never pass user generated data in to methods that either eval Ruby or call send directly if possible, but if you must then you must whitelist it first.
Tidy test setups with Factory Girl - Neil v B
http://cookieshq.co.uk/posts/useful-factory-girl-methods/
I was interested to read about some more advanced uses of Factory Girl that are outlined here. I've only really used the basics - defining a factory and then creating objects from those factories in test setups. This article describes how you can use the trait concept to extend your factories.
NakayoshiFork gem for Copy-on-Write in Ruby 2.2+ - Andrew W
https://github.com/ko1/nakayoshi_fork
Changes in Ruby 2.2 and later to the generational garbage collection algorithm means that new objects that are promoted to old objects end up marking their memory pages as dirty. So when the process is forked (e.g. a new unicorn process to process HTTP requests) and a GC run occurs afterwards it can end up copying memory needlessly, resulting in process memory bloat. The NakayoshiFork gem fixes this by patching the fork method to ensure that all new objects are promoted to old objects first before the actual fork takes place.
Hacking inclusion: How we customised a bot to gently correct people who se the word 'guys' - David B
https://18f.gsa.gov/2016/01/12/hacking-inclusion-by-customizing-a-slack-bot/
While the title is probably overselling the point of the article in typical click-bait fashion, the issue it addresses seems relevant. The use of the word 'guys' has come up at Unboxed as well as at GDS, with people (myself included) using it to address both genders where more inclusive terms such as 'people', 'team' etc could be used. The article explains how 18F customised their SlackBot to suggest corrections when the word 'guys' is used.
Opening GOV.UK's Puppet repository - Andrew W
https://gdstechnology.blog.gov.uk/2016/01/19/opening-gov-uks-puppet-repository/
Often whilst an app's source code can be made public (like the code for https://petition.parliament.uk lives at https://github.com/alphagov/e-petitions) the tools that are used to deploy the app and maintain the infrastructure are kept private because they normally contain a multitude of passwords and secrets. If it is done, then the normal approach it to reset the commit history after the secrets are removed but recently GDS published the Puppet code for managing and deploying the GOV.UK website and this blog post explains how they did it whilst retaining the commit history.
Track of the Week - Andrew W
I was a big fan of The The in the 80s when I was a teenager and when I heard of the recent passing of artist Andy Dog Johnson who did the fantastic cover for Infected I dusted off the CD and re-listened to it. It still sounds great some 30 years later so I had to choose the track 'Slow train to dawn' because it's what I seem to spend most of my time doing and it's a great collaboration with Neneh Cherry.
