Walmart had a similar recall last year for their Ozark Trail bottles. https://www.cpsc.gov/Recalls/2025/Walmart-Recalls-Ozark-Trai...

This reminds me a lot of Jason Fried (of 37signals, now known as Basecamp)'s complaints about Get Satisfaction back in 2009.

I've found my jobs' internal (social) message boards/mailing lists/Slack channels/etc to be great resources as the only contributors are those who work/worked at the company. Your (ex)coworkers presumably met/meet a certain competency bar and are less likely to spam. At larger companies there are message boards/mailing lists/Slack channels/etc for nearly every topic.

For local information, I've found forums for local sport teams to be great resources during the off season. Posters are often happy to engage in any sort of chat during the off season. Even if you haven't gotten to know the frequent posters during the sport's season you can use the (usually highly visible w/o any additional clicks) account age/# of posts/"karma" as a proxy of posters' trustworthiness. note: If you don't normally contribute on-topic (i.e., about the team and sport) posts, I would only search the forums for your questions and not post off-topic questions as that'll get you quickly banned.

This article relies heavily on findings by the Gottman Institute however the Gottman Institute's findings are suspect because they built their prediction models after the results are known and they never verified that their models hold up w/ additional data.

In machine learning parlance, it's equivalent to deriving a formula using training data and not checking if the formula is accurate w/ a validation data. I doubt many (anyone?) here would trust an autonomous car built w/ only training data and never tested w/ validation data. Similarly, I don't believe/trust the Gottman's prediction rate (94%) for a second.

Thanks for the response! To make sure I understand this correctly: If I find a product labeled as "HEPA" (w/o a prefix or suffix such as "type," "like", "style," and "99%") then I can be assured that the product does meet the standard of removing 99.97% of particles that have a size of 0.3 µm?

Can you expand on this? It does look like there are HEPA specifications[0]. Are you saying that a product that doesn't meet those standards can still legally be labeled as HEPA? Yikes!

Does the near-highway location of the house concern anyone else?

The correlation between near-highway air exposure and adverse health outcomes is well documented and I have not found a single study, article, etc that disputes the correlation. Below are three articles and snippets (emphasis mine) regarding the aforementioned correlation and how quickly the pollution levels drop over short distances from the freeway.

source: http://now.tufts.edu/articles/big-road-blues-pollution-highw... "Throughout the 1980s and early ’90s, dozens of studies found links between fine particulate pollution and cardiovascular health. One of the largest and most influential of these, the Harvard Six Cities Study, followed more than 8,000 participants in six towns across the Midwest and New England. Over 15 years, the initial phase of the study tracked each person’s health and measured particulate levels in the air over their communities. Its findings, first released in 1993, showed that even a minuscule increase in fine particulates (just 10 micrograms per cubic meter of air), could cause up to an 18 percent bump in cardiovascular disease." ... there’s reason to think that ultrafine particles, which the EPA does not regulate, are even more insidious than their larger counterparts ... ultrafines can fluctuate dramatically over the course of a morning or afternoon, depending on the weather and how many cars and trucks are on the road. Ultrafines are also confined to a relatively small area ... close to major highways, often spiking dramatically within a few hundred meters of the source."

source: http://www.scpcs.ucla.edu/news/Freeway.pdf "Studies conducted by SCPCS investigators here in LA show that carbon monoxide and ultrafine particles – the smallest portion of particulate matter emissions and potentially the most toxic – are extremely high on or near the freeway, dropping to about half that concentration 50-90 meters (~165-295 feet) from the freeway ..."

source: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1971259/ "People living or otherwise spending substantial time within about 200 m of highways are exposed to these pollutants more so than persons living at a greater distance, even compared to living on busy urban streets. Evidence of the health hazards of these pollutants arises from studies that assess proximity to highways, actual exposure to the pollutants, or both. Taken as a whole, the health studies show elevated risk for development of asthma and reduced lung function in children who live near major highways. Studies of particulate matter (PM) that show associations with cardiac and pulmonary mortality also appear to indicate increasing risk as smaller geographic areas are studied, suggesting localized sources that likely include major highways. Although less work has tested the association between lung cancer and highways, the existing studies suggest an association as well. While the evidence is substantial for a link between near-highway exposures and adverse health outcomes, considerable work remains to understand the exact nature and magnitude of the risks."

Here's a highly-rated detailed review that addresses the EcoSphere controversy. The author(s) appear to be very well informed. http://www.amazon.com/review/R39YUFJKTH4NEF/ref=cm_cr_dp_cmt...

The first part of Kareem Abdul-Jabbar's essay reminds me of Paul Graham's "What You Can't Say" (http://paulgraham.com/say.html).

Fair enough.

For the interim what do you and Mellow recommend customers use for a "temperature-safe bag" (per instructions on your website)?

Thanks for the heads up, pcl.

I was already aware but it's a great point and one of the many reasons I try to limit how often I dine out.

Thanks for the reply zemvpferreira.

How are you planning to solve the concern of plastic leaching while maintaining the benefits of sous-vide?

Thanks for the reply tptacek!

I tracked down Dave Arnold's report to 9:28 here: https://itunes.apple.com/us/podcast/cooking-issues-episode-1...

In summary: SC Johnson (SJC) told Grant Achatz and others chefs not to use their bags for sous-vide so Dave Arnold contacted SJC and asked specifically about using the bags for sous-vide and explained why he believes the practice is safe. The SJC representative replied with "Ziplock brand bags are designed to withheld being held in high temperature water including being used up to 82 degree Celsius for up to 72 hours." (quote at 12:05 of podcast)

I'd feel better if there was a specific statement about the safety of the food being held in the bag rather than an implication that since the bags withstand the bath the food isn't tainted.

What temperature-safe bags are out there?

I did some digging into this a few months ago and couldn't find anything conclusive. All I found were blogs, quotes, etc by wannabe scientists.

Of note:

• http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222987/

Nearly all plastics (even the BPA-free ones) leach estrogenic activity chemicals

• http://pprc.org/index.php/2013/networking/p2-rapid/do-plasti...

Basically said that there is little evidence in either direction

• http://www.codlo.com/faq.html#.Ux5Ly-ddWlg and http://www.chow.com/food-news/107898/cooking-sous-vide-in-pl... and http://www.sfgate.com/food/article/Author-says-use-of-plasti...

Says that bags made from polyethylene (PE) are safe while bags made from polyvinyl chloride (PVC) are not.

• http://www.beyondsalmon.com/2010/08/cooking-in-plastic-how-s...

SC Johnson (Ziplock manufacturer) themselves do not recommend cooking w/ their bags. Note their bags are made w/ the supposedly safe (per the links in the previous bullet) polyethylene (PE)

Right now I'm very intrigued by sous-vide but am too paranoid about the plastics to make the jump.

A bit pedantic but Warren Nyerges and his wife, Maureen Collier did not buy out the bank building and force the bank out of it.

Nyerges and Collier won, in court, reimbursement for their attorney fees and then had sheriff enforce the ruling who then proceeded with a foreclosure (which was on the furniture and not on the building).

Glad you're also excited!

You can currently use the app on your desktop browser using the same url (https://app.workshopcafe.com) and get the same feature set as you get on your phone (Except for things that require a phone like calling or texting in orders). No need to switch from your laptop!

Developer for Workshop Café here. The recently-released social features (Community Page) are definitely just the MVP. Would love to know what you think. We're going to see how people use it and add stuff we think is helpful. We've already noticed people putting their contact info and links to their personal pages, projects, etc. Hope it catches on!

Developer for Workshop Café here. Thanks for the mention!

If you or anyone else reading this stops by you'll probably see me on the Community Page (under the name "Newton") as I'm in the café often. You can see where I'm sitting so you can come introduce yourself!

Per pixeltrix's comment it appears that you're safe.

I'm an avid college football fan and the BYU athletic director's response doesn't seem right.

Roster depth is very important to a team for various reasons such as having players who can step in for injured players (important given the nature of football), allowing players to learn the system/schemes before playing (despite what many think of football it is complex and being able to "reload" rather than "rebuild" is key to the perennial powerhouses), giving players time to develop and grow before seeing game time (most are a mere 18 years old when starting college), being able to field scout teams for the starters to practice against, etc.

USC football is currently facing sanctions and lost 10 football scholarships per year for three years. Read any sports analyses on the sanctions and they'll tell you that the scholarship loss hurts USC not because so much because top recruits will be making something of themselves elsewhere but because it hurts USC's roster depth.

"Ladies night" is also illegal in California (among other states) though the practice is still relatively common.

Weighing yourself hourly to see how quickly you're burning energy is misguiding. When you burn carbs/fat you're not expelling them from the body. You're converting them to another form in a process that releases energy that your body can use. E=mc^2 considerations aside, as you wouldn't be able to detect those differences anyway, your weight is still the same. The waste products later get expelled when you go to the bathroom, sweat, etc.

I don't see the "for Hackers" angle in this article.

Yes, you can think through problems while lifting but that's hardly unique to weight lifting. Ditto for books on tape.

I'm not hating on weight lifting here (I've been lifting consistently for 9+ years) but I just don't see this as being Hacker News.

PS - I think you meant to write "read" instead of "ready" here: "In particular, the Freakonomics audio books are quite good as they are ready by the author, as is Outliers by Malcolm Gladwell."

If you can create arbitrage situations for customers you can generate a decent amount of buzz in certain circles. Off the top of my head one way to do it is to offer to buy gift cards for more than 95% of their value. Some people have credit cards that give them back 5% on grocery store purchases and many grocery stores sell gift cards. If the folks on FatWallet Finance (http://www.fatwallet.com/forums/finance) get wind of it (heck, post it yourself) they'll jump all over it and you've got immediate exposure to hundreds of people. I would set limits though and do it only sporadically lest you end up w/ a huge surplus of gift cards that may take you a while to sell.

To get a sense for the kind of exposure you can get here's a thread from another arbitrage situation (buy dollar coins from the US government at face value, collect credit card rewards/cash back, deposit coins into bank account). These guys went nuts and the US Mint policies were actually changed to combat it. There's an article somewhere from a press conference where the US Mint publicly addressed it but I'm too lazy to dig it up right now. http://www.fatwallet.com/forums/finance/837472

Also, on occasion people post in the forums questions like "How can I turn $X credit limit into cash." Set up relevant topic alerts (http://www.fatwallet.com/forums/alerts.php) and respond by letting them know they can buy gift cards and then convert them into cash on your site.

I'm a regular in that forum so let me know (contact info in profile) if you want any guidance in posting to FatWallet Finance.

Is there a way to view all the merchants you accept and what you percent you pay for them? I'm guessing the value depends on not just the merchant but also the value of the card and the expiration date so it may not be possible to just have a simple list view.

I ask because I'd like to refer you to a friend who has a boatload of credit card rewards points she needs to use and can get gift cards for the rewards points. If she could immediately see which merchant cards will give her the highest return it'd be a lot easier than tediously selecting each merchant and clicking "get offer."

What stops a scammer from writing down the relevant card numbers, selling the card to CardPool (or any competitor), and then still using the card after receiving payment?
