The Wiki entry also mentioned "two effects that lower the actual temperature needed", one being average kinetic energy and the other quantum tunneling "if [nuclei] have nearly enough energy." The term "nearly" isn't precisely defined though.
Your advice is somewhat dangerous if people follow it expecting them to magically work. First, the NASA study is for VOCs, not pm2.5. Second, when I briefly looked into using plants to clear VOCs indoors, I found that the number of plants, lights, and air-circulation required is completely impractical. Plants are awesome, I love them, but they're not enough. I wish it wasn't so.
People make decisions with their gut first, and then backfill their decision with "logic." We should be called homo irrational, not homo sapiens.

Add to that the amount of effort we expend to protect our egos and it's a wonder we ever arrive at correct decisions.
It is considered as a safe supplement. However, I have an awkward experience with artificially sweetened gum during my oral glucose tolerance test. I had pregnancy diabetes during maternity and my father had Type-II diabetes, so I did this as a check-up following child-birth. Before this test I fasted overnight, than went to the lab and drank a very sugary liquid. My blood sugar measured for at the beginning and hourly for 3 hours. I wasn't allowed to eat anything, or drink too much water. After the third measurement, I got very thirsty, also was feeling nauseated and asked if I am allowed to chew a gum to help moisten my mouth, and they said no problem. Gum not only helped moistened my mouth also helped me feel much better. I taught that was help of menthol. Than I got my results and there was a rapid increase in my blood sugar at the fourth measurement. Lab did not worry about the results because all my measurements was in acceptable limits. But how that measurement had risen became a mystery for me. I'm not sure which sweeteners that gum included, but it was a well-known gum brand with a clear non-sugar label.

In any means, I myself try to stay away from sugary drinks, and any kind of sweeteners as much as possible. If it's a special occasion, or a meal that I really like with a certain sugary drink as a side, I drink. But I don't replace with an artificially sweetened version. You will get used to live without them, and will not crave after a while.
Sclerosis from breathing that air? Or did the air only cause the lung infection
Indeed. It's less urban areas that have poor public transport that need this the most. The bay area for example is extremely hard to get around without a car, but something like Seattle? Very different.
Could you explain? I'm curious why it'd be better to have the air filter going rather than having good airflow from outside via open doors and windows? Are we trying to filter dust/ things produced in the house, or pollutants from things outside the house?
As pointed out elsewhere in the comments, Kroger chains already have this if you want to check it out.
Expanding on this, this 10KeV temperature is the average of all particles, and there's a distribution around this average. Some will be higher, and thus more capable of colliding with high energy.

In addition to that, whether two nuclei fuse is also dependent on how squarely they collide. A glancing blow intuitively allows both nuclei to push each other away a lot easier than if they experience a head-on collision.

A graph of the fusion rate such as [1] shows that even at much lower average temperatures, fusion will occasionally happen when two higher-than-average nuclei collide head-on. As the temperature gets higher, this rate increases as more particles have enough energy and less require those head-on collisions. The peak rate for D-T according to this graph is about 70kEv.

I can't speak to why the grandparent's link referenced 100kEv, as it's been a decade since I last studied this and I'm very rusty.

Ask HN: The best toilet time app for software engineers?
Noticed that lots of colleagues spend long time on the toilet (seriously, I am not joking...) that most of time I need to wait for a toilet (for No.2) on a floor with ~100 male and 5 toilets (not sure about the female side). I guess smartphone and wifi are the culprit of the longer time. Now that the longer toilet time becomes a trend, just wondering whether people have their most enjoyable/time-killing toilet time apps to share here?

Ever had this discussion with a coworker?

Coworker: "I hadn't enough time to do it right"

You: "Given enough time, how would you do it differently?"

Coworker: "............" (crickets)

IMHO it's not related to deadlines only ; the "not enough time" argument is often a comfortable fallacy, keeping us from facing the limits of our current skills.

I found it to be especially true with testing. I've lost the count of how many times I heard "we didn't had time to write (more) tests". But testing is hard. And when given enough time, these developers don't magically start doing it "right" overnight.

There's an interesting anecdote in the chess world. Mikhail Botvinnik [1] was a longtime former world champion and would go on to become the 'patriarch' of Soviet chess, which would dominate the world scene in chess for many decades. In the early 60s a child was invited to Botvinnik's school for an assessment and possible training. Upon evaluating the child and his games and 'feel' for chess, Botvinnik remarked, "This boy has no clue about chess, and there's no future for him in this profession."

The boy he was talking about was Anatoly Karpov [2]. Karpov would go on to become world champion once Bobby Fischer failed to defend his title. But far from winning by default he took the title and held onto it for many years becoming one of the most dominant and active world champions of all time. He ceded his title only once once Garry Kasparov came onto the scene.

And really I think these sort of anecdotes are rife among many who go onto achieve great things. One of the many reasons I think the current trends in school of trying to encourage and reward children, particularly taken to the extreme with things such as participation trophies, are likely deeply misguided and being driven by intuition rather than data in an area where the latter often contradicts the former.

That's interesting to hear; I'm not in ketosis, but have a pretty non-standard diet from an American perspective[1], and part of what's kept me doing grocery/cooking from scratch and away from meal kits and other similar solutions is that they seem pretty poorly tailored to my bare minimum of a healthy diet. A friend gave me a $30 referral discount to HelloFresh and I tried out one shipment and gave up on it, for pretty much precisely this reason. I guess I should take a deeper look at their options for special types of diets, or maybe even

> It's difficult to make your own ketogenic meals solely via your own grocery shopping and recipe research

I'm surprised to hear this even more. Have you tried Googling "keto recipes [other search terms]" and meal-planning around it? If you've already tried this, I don't intend this to be patronizing; I'm actually relatively new to cooking most of what I eat, which means things like meal planning are actually pretty new to me. I've just found it to be a really effective way to organize frequent cooking, and once you build up a bit of a repertoire of recipes, it doesn't really take any extra time beyond putting the ingredients and Instacart order together.

That's fascinating and gave me a genuine laugh.
I bought the Dylos almost 5 years ago. At that time I don't think the SDS011 was available.

A cool feature of the Dylos is monitor mode. It wakes up every hour, spins the fans for 1 minute, and spits out a measurement. It's convenient for 24/7 monitoring because it reduces fan noise and dust accumulation. I don't know if the SDS011 offers something similar, or if you could somehow program that yourself, but that may be something to consider.

I'm very happy with the Dylos overall. In addition to being 5 years old, mine has been running in monitor mode for the past year and a half with no issues so far so I really can't complain about reliability. Issues are size, fan noise, antiquated UI, and also antiquated connectivity, although I personally enjoyed working with serial (threw me back to early Duke Nukem LANs before we moved to IPX). I wouldn't be surprised if there are superior alternatives today, at least regarding usability.
It would be stupid to expect plants to clean up PM 2.5 material. The best they can do is chemicals. Sure they aren't a perfect solution but then again, anecdotal evidence from my childhood says thatmore plants are better for our environment. Indoor/outdoors doesn't matter.

And yes it isn't a magical solution, we have to be careful while placing plants in our house.

hardly, for shooters it will become very frustrating very fast, because a lot of the time you're going to get outrandomed rather then outskilled.

According to Forbes [1] it’s 1/88 for any kind of vehicle accident. 1/303 specifically in a car crash, which is definitely a lot lower than the original 1-2% quoted (though I’m sure it varies depending on where you live). Also, I guess even bikers don’t ride 100% of the time in place of being in / around cars.

That file doesn't even exist on my system, but in any case public means official, not in some header.
The unity game engine and everything worked really well though. It immediately used my HOTAS controllers, which I wasn't expecting. Impressive demo!
I use this same setup and it works great. Been doing it for years.
The worst program I ever worked on was something I was asked to maintain once. It consisted of two parts. The first was a web application writen in ASP. The second portion was essentially Microsoft Reporting Services implemented in 80,000 lines of VB.NET.

The first thing I did was chuck it into VS2010 and run some code metrics on it. The results were, 10 or so Methods had 2000+ lines of code. The maintainability index was 0 (number between 0 and 100 where 0 is unmaintainable). The worst function had a cyclomatic complexity of 2700 (the worst I have ever seen on a function before was 750 odd). It was full of nested in-line dynamic SQL all of which referred to tables with 100+ columns, which had helpful names like sdf_324. There were about 5000 stored procedures of which most were 90% similar to other ones with a similar naming scheme. There were no foreign key constraints in the database. Every query including updates, inserts and deletes used NOLOCK (so no data integrity). It all lived in a single 80,000 line file, which crashed VS every time you tried to do a simple edit.

I essentially told my boss I would quit over it as there was no way I could support it without other aspects of work suffering. Thankfully it was put in the too hard basket and nobody else had to endure my pain. I ended up peer reviewing the changes the guy made some time later and a single column update touched in the order of 500 lines of code.

There was one interesting thing I found with it however, there was so much repeated/nested if code in methods you could hold down page down and it would look like the page was moving the other way, similar to how a wheel on TV looks like its spinning the other way.
Every single time I see a similar article on Javascript, I feel so lucky for being able to use Clojurescript instead.

It is probably similar to the police seizing your keys or combinations for locks to a storage unit and you changing the lock on the storage unit.

The police can just go to google or slack with a warrant to get the evidence. The physical equivalent would be going to the storage unit proprietor and cutting the lock.

IANAL but I would expect it to count as "hindering a police investigation", obstruction of justice, or something similar.
Hand Arthritis Treatment at NYC Stem Cell Institute
The hand and wrist have different little joints that cooperate to deliver movement, including the fine movement expected to string a needle or tie a shoelace. At the point when the joints are influenced by arthritis, exercises of day by day living can be troublesome. Arthritis can happen in numerous territories of the hand and wrist and can have in excess of one reason.
After some time, if the arthritis isn't dealt with, the bones that make up the joint can lose their ordinary shape. This causes more agony and further points of confinement movement.
Essentially characterized, arthritis is irritation of at least one of your joints. The most widely recognized kinds of arthritis are osteoarthritis and rheumatoid arthritis, however, there are in excess of 100 distinct structures.
Sound joints move effortlessly as a result of a smooth, dangerous tissue called articular ligament. Ligament covers the closures of bones and gives a smooth skimming surface to the joint. This smooth surface is greased up by a liquid that closely resembles oil. It is delivered by the joint coating called synovium.
At the point when arthritis happens because of illness, the beginning of manifestations is steady and the ligament diminishes gradually. The two most regular types of arthritis from ailment are osteoarthritis and rheumatoid arthritis.
Rheumatoid arthritis is an incessant infection that can influence numerous parts of your body. It causes the joint coating to swell, which causes torment and firmness in the joint. Rheumatoid arthritis frequently begins in the little joints of the hands and feet. It more often than not influences similar joints on the two sides of the body.

Yeah, sorry, just assumed that pollutants were coming from outside. I'm just so used to it after living several years in China and now being affected by California wildfires. If the outside air is better than inside, then yeah you probably should air out your home as much as possible unless it's unbearably hot or cold outside :)
Had something similar happen to me. I gave a new guy a task of 'figure out luigi or airflow to help us process nightly data better than crontab'.

He came back with a custom python/c++ framework where literally every function was called handle(), and in c++ it used type inference to figure out which handle() to call.

Apparently this is what he wrote for his last firm.

We quickly found something else for him to do but he didn't last much longer after that anyways.
I mean, in 2018, I'm scared witless of all that. Anything cached in background to someone else's computer by something as unstable and slow as ECMAScript is just... a very bad idea. Keep programs local, and don't use Web coding / scripting for anything but the Web itself through a free-standing browser.

Two noob questions:

What are the technical reasons that glibc cannot adhere to the Linux dogma, "Don't break userspace?"

Since glibc does not adhere to that dogma, why the decades-long reluctance to add certain syscall wrappers? If they screw up and make a bad interface just modify it and bump the version number.

> I don't really care too much about getting the perfect vegetable, as long as it's not spoiled and tastes reasonably good, I'm happy with it, and I want to spend as little time as possible.

Ordering takeout is the most efficient way to cater to people in this slice of the market. The intersection of people who don't intimately care about their ingredients and people who want to cook is very small. Most people who want to minimize time spend on food would not entertain the idea of cooking serious meals at home.
Safer system programming languages with good type systems are like a drug that make it impossible to go back to C.

My first drug was Turbo Pascal, from 4.0 all the way to TPW 1.5.

Naturally the only thing C had going for it was being a language with an OS. As in regard to its features it was already unatractive in 1990 for me.

Thankfully in 1993, C++ was already an option that also came with an OS, as it became adopted by OS vendors in their SDKs.

If that's the case why Firefox Accounts is not really designed with the end-user in mind? The design totally looks like a nice walled garden, completely custom and non-interoperable.

Just a few quick examples:

1. There's HAWK and OAuth2 and BrowserID there, all in the same system. That's a lot of undesirable extra complexity.

2. The Sync 1.5 protocol itself is full of non-standard weirdness, with odd stuff like X-Last-Modified (which is just like Last-Modified but with UNIX timestamp - seriously?). While I haven't experimented writing an adapter yet, I strongly suspect a plain old' WebDAV (with a tiny little bit of sub-standard collection stuff) would've worked just fine and even better.

3. Poor documentation. The documentation was draft quality when Accounts and Sync were just rolled out (so it required some reverse engineering), but that's understandable. Things have improved since then but I believe a lot of stuff isn't really fully documented even today. For example, some undocumented magic is required to show Accounts sign-in page on iOS.

My point is, the whole thing is absolutely not developer-friendly (unless you're a Mozilla developer), as it makes self-hosting and alternate implementations quite difficult.

Maybe my problem is Accounts and Sync is not a standard (neither a proposal to become one), but just a documented vendor-unique API.
