What about the advice to put it on the “warm-in-winter” side?If that really mattered, do you think the U.S. building code would have dropped the requirement to use paper-faced batts? The warm-in-winter suggestion says that if you’re trying to limit the diffusion of water vapor, put the vapor retarder on the humid side of the wall, where … uh … it’s not able to retard much vapor.In a really, really cold climate, it may matter, but even in Maine and Ontario, vapor retarder paint would be a better way to go. If you want to slow down the vapor diffusion, why not do it before it hits the drywall?So just relax. If your building inspector wants you to put the kraft paper on the “wrong” side, take another look at the graph above and be comforted that it doesn’t really matter. Then go get yourself some unfaced batts (and do your best to install them to Grade I quality).~~~~~~~~~~~~~~~* Speaking of fiberglass batt insulation, Carl Seville (a.k.a. the Green Curmudgeon) wrote another article on poorly installed batts recently, with photos of Knauf fiberglass. Rather than being a bully, like Guardian did to me a couple of years ago, they commented on the article and asked for a dialogue on how to get better installation in the field. Kudos to Knauf!â€ My friend Abe Kruger likes to say that you should treat building inspectors like wild animals. You have to approach slowly and quietly because they spook easily. In the HERS rater class I taught in Toronto this week, I used that analogy but before I could get to the reason why they’re like wild animals, one of the students said, “You mean we can shoot them?” Why doesn’t it matter?First, the kraft paper is a vapor retarder meant to reduce the potential for moisture problems caused by diffusion. That sounds like a good idea, but the vast majority of moisture problems are caused by air leakage, not diffusion, even in places like Maine. Do the air sealing; stop worrying so much about vapor retarders. Second, if you install it the wrong way, it’s unlikely that you’ll have a problem. I suggest you read Joseph Lstiburek’s paper, Mind the Gap, Eh! The graph below, from that paper, shows the water vapor permeance of kraft paper as a function of relative humidity.As you can see, the permeance of the kraft paper rises as the relative humidity rises and hits 10, the point at which we describe a material as vapor permeable, when the RH is 60%. The upshot here is that if you put the kraft paper on the wrong side and it gets wet, it won’t trap moisture. The wetter it gets, the better it dries. If you put it on the right side, where the humidity is, it’s not much of a vapor retarder, because that’s where it becomes vapor-permeable.Also on the graph is the permeance of polyethylene. As Dr. Joe says in the article, “Plastic vapor barriers really are vapor barriers when things get wet. Not so asphalt-saturated kraft paper. And most walls with asphalt-saturated kraft paper thank the building science gods for the difference.” RELATED ARTICLES Do I Need a Vapor Retarder?Vapor Retarders and Vapor BarriersForget Vapor Diffusion — Stop the Air Leaks!When Sunshine Drives Moisture Into WallsQuestions and Answers About Air BarriersQ&A Spotlight: Vapor Barriers Redux Joe Lstiburek Discusses Basement Insulation and Vapor RetardersJoseph Lstiburek: Air Barrier or Vapor Barrier? If you install fiberglass batt insulation* with a kraft paper vapor retarder in a home, which way do you face the vapor retarder? To the inside of the home or the outside of the home? For many building science questions, the answer is, “It depends.” For this one, however, the answer is clear.SPOILER ALERT: The answer is in the next paragraph — so if you’d rather wait and find out when you see the movie in the theater, don’t read any further.The answer is: It doesn’t matter.

Two men come on a scooter, hands over a carton to a security personnel. Three others come in a mini-van with a drum full of rice and another full of Rajma. It was Rajma Chawal for lunch on Monday for many security personnel manning Sirsa where the Dera Sacha Sauda has its headquarters. The food, however, is provided by locals and several community organisations as a token of appreciation to the force of nearly 4,000 who have been working relentlessly since Thursday. The town is protected by 40 security companies including the Army, Border Security Forces, local police amid others whose primary job is to maintain law and order and minimise violence anticipated in the wake of circumstances. Mukul, 30-year-old businessman who stays in the next street to Satnam Singh Chowk where the concentration of security personnel is dense, ordered a bakery to produce 1,000 vegetable patties on Thursday as breakfast. In the evening, they were treated with bread pakoda and chai; not to mention, the endless supply of water. “Little joys of life in such tough situations,” smiled Constable Ajay Kumar as he facilitated the entry of a food truck. “They’ve been working day and night just to protect us. This is the least we can do for them,” said Rajnish Sharma, Mukul’s friend who pitched in money for Thursday’s breakfast. Sarabjit Singh, sarpanch of Vaidwala village, a few km away from the Dera where stands a police check point, along with her mother Manjit Kaur (65) has been hosting two meals a day for the force since August 25. “Today, it’s chhole, chawal and roti. My mother and wife cook for nearly 150 people both the times and there’s nothing more rewarding,” he said.Not only are the locals making sure that the jawans are well fed, several organisations like the Roti Bank, Jain Samiti and Kanhaiya Manav Sewa Samiti are voluntarily providing food and water to the security personnel. How are they getting the ration when shops are closed is a question answered by Sushil Kandoi, 54, of the Roti Bank. “We just started doing it. As the word spread, help started pouring in in terms of money, pulses, rice and vegetables. I never asked anyone for it but we’re all humans after all,” he said referring to all the grocery shopowners who’ve been providing the organisation with raw material. The overwhelmed security personnel return the favour with a ‘Thank you’. “We feel very happy when people think about us. Who doesn’t? Accha lagta hai jab hamari mehnat ko pehchana jata hai [It feels great when our effort is recognised],” said Constable Jitender Kumar.
Earlier this week, we read with interest in The New York Times that Davidson College’s math department is helping its men’s basketball team win games. Since this combines three of our favorite subjects — sports, math and using math to win at sports — I asked Tim Chartier, a professor in Davidson’s mathematics and computer science department, to elaborate on the unusual partnership between his department and the Wildcats.He was understandably reluctant to spill too many details — particularly regarding how the math department analyzed the data about Iowa, Davidson’s round-of-64 opponent in the NCAA tournament Friday, or Gonzaga and North Dakota State, one of which Davidson will face if it reaches the round of 32 and both of which he’d already started scouting. But Chartier did shed a little more light on the math behind the surprise Atlantic 10 champs. And it sounds a lot like what we do at FiveThirtyEight, except with a goal of winning basketball games instead of writing articles about winning basketball games. Here are edited excerpts of his reply:So, what do we offer the coaches?Heat maps: Two members of Cats Stats, as we call our group, track the games for heat maps. They mark who takes a shot and estimate the location by clicking a computer program that I wrote. Then, as you see, regions of the court are marked as hot and cold regions. Two members of the group met with coaches in January and went through heat maps not just at the team level but player level and then various combinations of players. The coaches found this very helpful and discovered things that led them to analyze player combinations with similar tendencies that they then recognized.Lineup efficiencies: Here we show Dean Oliver’s Four Factors for offense and defense for every five-man lineup and the total amount of time that lineup has been used. Then, we also found various subsets of lineups, as well, like guard trios and forward pairs. For example, we might see that two big men are most efficient/inefficient when in the game together.Personal scouting: Here we produce a detailed breakdown of players’ tendencies and how well they performed in each aspect of the game. Here no new statistics were created. We presented data and numbers so that the coaching staff could easily implement the reports into their game plan. It could range from things like whether or not a player liked to shoot off the dribble and how effective they were in those situations to things like how effective a player might score driving left out of isolation situations. Said another way, we look for the tendencies in the numbers, especially outlier numbers. We think of these as creating data points or dots. Then, we dig into the video that accompany these stats on Synergy and figure out the story/tendency behind the number. That gives context and, in a sense, connects the dots. For example, if a player drives to the right 80 percent of the time and scores much better than going left, that is important. But, then the video can help see that his first step when driving is quicker going right than left, allowing him to beat his man more often.

Reliance Jio launches free 4G feature phone aka ‘JioPhone’ with unlimited voice, dataRIL AGM via YouTubeMukesh Ambani’s Reliance Jio has seen phenomenal growth over the last two years. After disrupting the telecom market with its cheap plans, the company is now eyeing the lucrative entertainment industry with plans to set up its own production house.The news comes from an unnamed source, who told Livemint: “Content market is still not properly tapped… Reliance has hired a bunch of scriptwriters and content creators and is in the process of setting up a huge production house.”If the report is accurate, it would mean that the company will create its own web series and short film taking on Netflix and Amazon’s over-the-top (OTT) services. The conglomerate will be banking on its 215 million subscribers to ensure the service is well received, and with plans to roll out JioGigaFiber, that number will only be higher.Currently, Jio offers video content in partnership with third-parties such as ALT Balaji, Eros and Reliance-owned Viacom through its Jio Cinema app.At a shareholder meeting recently, RIL chairman Mukesh Ambani said that video consumption has grown from 165 crore hours per month to 340 crore hours per month. The rise in part is due to the lowering cost of data plans, that Jio introduced when it entered the market.The report said that the content ecosystem business is being spearheaded by Jyoti Deshpande, former managing director at Eros. She has joined Reliance as head of the media and entertainment business. The source went on to add that Reliance has already got 20-25 creative people on board, and is targeting launch within 4-6 months of some web series. RIL has been aggressively expanding its presence in the OTT space, having purchased 24.9 percent stake in Balaji Telefilms last year, and 5 percent stake in Eros International in February this year. Earlier, Jio and Hotstar partnered up to offer JioTV to users. Reliance also owns Viacom18, which has a wide variety of entertainment channels such as Colors and MTV. Sacred Games posterTwitterWhile Jio’s entry into the content space is unlikely to shake up Netflix and Amazon’s dominance in the short run, it will have massive implications in the long run despite both companies investing heavily in Indian content. The news will also be good news for budding artists, who are looking for a big break and now have more options to chose from.
-The Anti-Corruption Commission has recommended that the cabinet division take punitive action against 97 teachers of eight educational institutions in Dhaka city allegedly for their involvement in private coaching centres. The graft watchdog sent a letter to the cabinet division in this regard on Sunday, ACC deputy director (public relations) Pranab Kumar Bhattacharya told Prothom Alo on Monday.Of the 97 teachers, 36 are from Ideal School and College, 24 from Motijheel Model High School and College, seven from Dhaka Viqarunnisa Noon School and College, five from RAJUK Uttara Model College, 12 from Motijheel Government Boys High School, four from Motijheel Government Girls High School, Khilgaon Government High School, one from Khilgaon Government High School, and eight from Dhanmondi Government Boys’ High School.The ACC, in the letter, said the cabinet division can take punitive action against the teachers of government educational institutions considering their activities as breach of government service rules.Earlier, the ACC recommended transferring 522 teachers of the city’s government schools, who have long been working at the institutions, outside the capital as they are allegedly involved in teaching in private institutions disobeying government instructions.
US Secretary of State Mike Pompeo shake hands with Saudi foreign minister Adel Al-Jubeir in Riyadh. Photo: ReutersWashington’s new chief diplomat was to meet Saudi and Israeli leaders on Sunday to rally coordinated opposition to Tehran and brief them on President Donald Trump’s threat to end the Iran nuclear deal.Secretary of State Mike Pompeo touched down in Riyadh on Saturday shortly after Tehran-backed Huthi rebels in Yemen fired missiles across the kingdom’s border.US officials travelling with Pompeo told reporters the Huthi missiles had been supplied by Iran, and cited the attacks as evidence that regional powers should work together.Pompeo had dinner with Saudi Arabia’s crown prince Mohammed Bin Salman, and on Sunday he was due to meet his father king Salman.Then he was due to fly on to Jerusalem to meet Israeli prime minister Benjamin Netanyahu and then on to Amman in Jordan, wrapping up a weekend of talks with some of Iran’s most fervent foes in the region.Trump is due to decide on 12 May whether to reimpose nuclear-related sanctions on Tehran, putting in peril the landmark 2015 nuclear accord, which most world powers see as key to preventing Tehran from getting the bomb.But Trump and America’s Middle East allies argue the deal, approved by Trump’s predecessor Barack Obama, was too weak and needs to be replaced with a more permanent arrangement and supplemented by controls on Iran’s missile program.Pompeo set off on his first diplomatic trip within two hours of being sworn in on Thursday and on Friday—after talks with the NATO allies in Brussels—he appeared to suggest that Trump plans to nix the deal.“Absent a substantial fix, absent overcoming the shortcomings, the flaws of the deal, he is unlikely to stay in that deal past this May,” Pompeo told reporters in at NATO headquarters.Perhaps the last chance to fix these supposed shortcomings came from talks between Washington and its European allies Britain, France and Germany on a supplemental agreement to sanction Iran’s missile program.But both President Emmanuel Macron of France and Germany’s Chancellor Angela Merkel left Washington this week after talks with Trump having failed to secure any promise that he might keep the core deal alive.Air strikesThat may be music to the ears of the Saudi and Israeli leaders, who both support a tougher line on Iran.“This administration has made it a priority to address Iran’s missile programs,” a senior US official told reporters in Riyadh, condemning the latest Huthi volley of missiles, themselves in part a response to Saudi air strikes.“Iran supplies the missiles that the Huthis fire into Saudi Arabia, threatening civilians,” he said. “Today alone the Saudis shot down four Huthi missiles, the latest in a string of such attacks.”Earlier, a civil defense official had said that at least one Saudi had been killed by falling shrapnel as his government’s air defense batteries attempted to intercept the missiles near the Yemen border.A Saudi-led coalition air strike overnight Friday to Saturday killed dozens of Yemeni rebels including two commanders, state media said.Prince Salman and his father will welcome US solidarity against Iran—just as Israel will want to see greater US support for its efforts against Iranian influence in Syria and Lebanon—but Pompeo has come with requests too.According to US officials, while Riyadh has a right to self-defense, it must come to see that the solution to Yemen’s civil war will be a political one and its forces must not exacerbate the massive humanitarian crisis there.Washington also wants to see an end to the Gulf crisis that has seen Saudi Arabia and the United Arab Emirates impose a diplomatic and trade embargo on fellow US regional ally Qatar.And, perhaps most importantly for Trump, Pompeo will urge Saudi Arabia to provide personnel and funding to help US efforts to stabilize northeastern Syria in the wake of the expected defeat of the Islamic State group.“The president has made clear that he wants to see meaningful participation from states in the region,” another senior US official travelling with Pompeo’s party said.“We want to see the kind of participation, for financial efforts, not just kinetic efforts that would match, parallel, would assist, the US role,” he said. The United States has more than 2,000 troops in Syria.On Qatar, the US officials said they do not blame one side or the other, but want Riyadh and Doha to sort out the stand-off themselves.Humanitarian tragedyAnd on Yemen, they warned the Saudi-led coalition not to again block or bomb ports that supply vital civilian aid, warning that there is no military solution to the crisis.“The humanitarian situation in this tragic country cannot be allowed to become worse. It needs to get better. And that means full and free access to humanitarian goods, to commercial goods, to fuel,” one said.Pompeo will conclude his first diplomatic trip on Monday after talks with senior Jordanian officials and then fly back to Washington to move in to his office in the State Department.
