Yes, they definitely do, although to a various degree of effectiveness. If you get a Xiaomi Mi Air 2, for example, it will be very effective. If you get a Dyson fanless thing, not so much.

In general, there is no escaping physics: you need to move a large quantity of air through something that traps dust particles. The low-tech solution of a fan and a HEPA filter is a very good one, but I would suggest getting a filter that traps PM2.5 particles as well.
In this case the chances of success are even lower, given the track record of the company doing it.

Which involves as stellar things as delivering a not-working (but "valid under contract" so we couldn't sue them) system for logistics management (everything from ensuring parts are on the shelves to assigning jobs to technicians and pilots for a mission) that we later found was rebranded broken car logistics support software, something that was found 3 years post original delivery date by new employee of a team working on fixing it - which meant we had to rework a crucial module.

Said software had gems like JS copied from geocities in 1998 handling drop down menus (which were broken unless very specific browser versions were used) - in 2012. (original delivery date was 2009~2010).

The "redo" contract is going to the same guys who just did the failure, and I've seen no mention of removal of one of the bigger pain points, which was use of cloud.

I think if doing this I would have a group split so one has to create an app that's finished (defining that would be fun) and one that has to write one that's code is 'clean' (again, fun defining that).

I say this because I've worked with a lot of inexperienced developers that commonly have a stack of half finished projects, or things they've re-written half a dozen times to get the architecture right. I'm my experience you learn a lot by finishing things, and being constrained by previous decisions.

Air quality test before and after or it doesn't work.

I am very suspicious with regards to air purifiers. Have you ever seen real HEPA filter? It is thick and it is quite difficult to push air through it. I can't imagine small PC fan that is designed to push air through UNOBSTRUCTED space will make any significant flow of air. I have spent some time with the guys who build PCs and who know great deal about fans and one thing I learned even an object that the air has to pass around or any kink in the path of air can severly impact performance of PC fan. Because they are designed to be quiet and still provide good flow of air they produce almost no pressure differential to speak of and the flow can be halved by a wire mesh that is a bit too dense.

You need to cycle the air in your room through the filter couple of times to clean it, assuming your filter is any good.

The cheap fan in the picture would barely be able to cycle the air in a small room maybe once an hour, if it was completely unobstructed. It is very likely that with any kind of HEPA filter the flow will drop by an order of magnitude.

Go with suggestion of other readers. If you want good, cheap filter, use a box fan and especially one that was designed to give good pressure difference. Take large cardboard or plastic box and mount large HEPA filter in it so that the air has to pass through. The larger the surface of the filter the easier time the fan will have to push the air through it and more efficient it will be.
Before I switched to another password manager, LP has:

- constantly managed to lose newly generated passwords

- consistently failed to register new passwords with the Safari extension

- failed to autofill credentials on many websites

I had used LP for years, but these problems never went away despite these being a failure of core functionality. After I finally switched to an alternative password manager, I was pleasantly surprised at how well everything seemed to work in addition to a much nicer UI.

In LP's defense, it's great that they offer such an important service for free, but I'd really prefer my password manager to be of more higher quality.

Zeroing memory is probably already really fast compared to other things the system is doing. Something that happened to me a couple years ago: I was writing a benchmark that needed a lot of memory. I just used a vector<char> for that. Of course, the vector zeroes the memory, so I thought hey, I don't actually need it to be zeroed, so why not just use unique_ptr<char[]>? Well it turns out (and most people here probably know what's coming next) that when you reserve memory, you don't actually get any physical pages. They get reserved as you access them. And since apparently the access pattern was worse (or something to that effect), the benchmark ended up running way slower than it did without explicit zeroing, even if I put the zeroing into the benchmark which it hadn't been previously. It turns out compared to reserving memory, zeroing was essentially inconsequential. So I'm not too optimistic that there are a lot of gains to be had here.

This is where things get mixed up. EPIC is suggesting that using Google Cloud is somehow equivalent with handing data over to Google so that Google works with that data.

These are absolutely, extremely different. Assuming that Google will somehow break into your VMs or GKE clusters to get data out and monetize it is crazy, of course, but EPIC tries to suggest that.
So cheat! If you use a physical calendar, you can mark those days with another symbol, like an arrow to show that the chain carries on. If you use an app, you can mark the day anyway, knowing that you had a legitimate reason to skip it.

Think of all the benefits you would get from practicing 95% of the days marked, compared to a much lower percent without the chain. Don't let the 5% or 1% stop you.

As an aside, this is my view of veganism. When I talk to people who say they can't go vegan because they'd miss cheese too much, or kebab, or whatever, I suggest they go vegan and keep eating cheese or kebab. 95% is a lot better than nothing!

That said, I can't do chains. I get anxious after a while carrying a long streak, and will either conveniently forget a day and mess up the streak (and feel relieved), or decide during a streak that I'll stop at 30, or 100, or whatever, just to give me permission to get off the treadmill. I don't like when enjoyable things turn into a chore.

Some apps are nice and let you go back and add marks even if you forgot to do it on the day. Some apps, like Duolingo, let you unlock tokens that protect your streak if you miss a day. But some apps are really strict, which can be annoying if you finish something after midnight and realize that you just broke the chain. My wife had that with a writing app where she finished exactly at midnight, which counted for the next day and her streak was broken.

So if I did a chain, I'd use a text file, or a paper, or send myself an email a day logging that I did the task. I wouldn't trust an extremely rigid app, because, as you say, there can be legitimate reasons why you miss.
The OP is highlighting maths because deep learning in particular makes use of some light calculus and linear algebra, and the OP is probably mixing together AI, machine learning and Deep learning (as is common today, unfortunately, and I can't blame the OP for that, everyone's doing it).

However, there is a lot more to AI than high-school maths and I don't just meean -more maths. I mean knowledge, lore if you like. It's a field with a long history, stretching back to the 1930's even (before it was actually named as "AI" in Dartmouth, in the 1950's). A lot of very capable people have worked on AI for a very long time and have actually advanced their respective sub-fields each with leaps and bounds and it's not very sensible to expect new leaps while being completely clueless of what has been achived before. You can't stand on the shoulders of giants if you don't know that there are giants and that they have shoulders you can stand on.

Unfortunately, most people who enter the field today know nothing of all that, or even that there was an "all that" before 2012 (if they even know what happened in 2012; and to be honest, one wouldn't understand what 2012 means if one doesn't know what came before). So on the one hand they are not capable of making leaps and on the other hand they don't even know what a leap would look like. And probably think that a "leap" is a 10% improvement of the state of the art for a standard classification benchmark.

I agree with you though that what is needed to make leaps in AI is curiosity. Lots and lots of curiosity. Vast amounts of curiosity. Curiosity of the kind that you only find in people who are a bit zbouked in the head. Or just people who have a lot of time in their hands, to study whatever their fancy tells them to.

So- not the kind of person who flashcards The Deep Learning Book, if nothing else because that means the person doesn't have the time to, you know, actually read the damn book well enough to grokk it.

Yes it mostly happens in young-er individuals because the reasons behind it are most likely genetic/hereditary and thus these people often don't live long enough to die from them later on. Some reasons include hypertrophic conditions( I'm not 100% sure on the english terms and I'm still an undergrad). Other reasons have to do with problems on ion channels which cause issues with electrical signals traveling through the heart resulting in ventricular fibrilation( e.g. Brugada, but you might have had episodes of passing out in the past). Some of this stuff is detectable but it's hard and there's no effective screening of the population. You might want to get checked by a specialist if you have a family history of early sudden deaths.

Environmental factors include things like steroid abuse( often in conjunction with amphetamin usage, see Rich Piana suspicions).

>Why would anyone choose this?

It's about clear communication of a commitment to users and licensees. It's about building trust, and hence strengthening and broadening the community around the software.

I licensor can know that they never intend to re-license code commercially, but their users and licensees can't know that in the same way. Without a clause like this have to take that on trust and some might choose not to do that, missing out and weakening the adoption of the code and it's community. The presence of a clear commitments avoids that problem.

Duolingo has streaks built in but it allows you to buy a "Streak freeze" with a virtual currency that you earn by just using the app. When you skip a day, the freeze will be automatically consumed and you have to buy another. You also can't have more than one.

I find this system very effective without being frustrating. Even when you skip a day, you have to at least open the app to buy a new freeze.
> Skunk works can sustain, at max manpower. It is bureaucratic waste with minimum productive output. My 2c.

Isn't the idea of skunkwork projects exactly to avoid bureaucratic waste for the sake of radical innovation?! Let me give three quotes from https://en.wikipedia.org/w/index.php?title=Skunkworks_projec...:

"A skunkworks project is a project developed by a relatively small and loosely structured group of people who research and develop a project primarily for the sake of radical innovation."

"Everett Rogers defined skunkworks as an "enriched environment that is intended to help a small group of individuals design a new idea by escaping routine organizational procedures.""

"[T]he term [skunkworks] was generalized to apply to similar high-priority R&D projects at other large organizations which feature a small elite team removed from the normal working environment and given freedom from management constraints.".

In this sense, the projects you are talking about surely cannot be skunkwork projects, but are just ordinary cooperate projects with a huge conservative cooperate-bureaucratic structure.

The problem is that Google has the most obvious conflict of interest of all cloud and AI providers when it comes to data use.

Many people simply don't believe anything Google says, and even those who do believe them to some degree know that others won't.

Google has become a reputational hazard in fields that deal with sensitive data such as healthcare.

Some decisions made by current management don't help at all. Instead of separating the advertising business from other activities like cloud and AI, they are moving in the exact opposite direction.

Why? I find this entirely baffling.
>The larger the surface of the filter the easier time the fan will have to push the air through it and more efficient it will be.

This is quite true. Assuming the media in your particle filter is of sufficient quality, the most important metric to look at is the aggregate surface area. The larger the surface area, the more air you will be able to move through it and the more particulate matter it will hold before requiring replacement.

Particle filters use pleated media for this reason. It's not uncommon to see a filter with 1 square foot face having 50 square feet or more of media. Without specs, the thickness of the filter and the density of the pleating will give you a decent estimate of the filter area. To improve performance and longevity further, it's also typical to have a coarser, pre-filter.

The machine itself is just a fan to push air through the filter and as noted, any reasonably powerful fan will do a sufficiently good job. High quality machines are only really required where you're filtering air before it enters a given area (e.g. LCD/semiconductor plants), and thus cannot afford to have any unfiltered air leak past the filter.
Miscarriage affects more like 1 in 3 pregnancies.

That number won't change. The main cause of miscarriage is that the embryo/foetus has a massive problem and can't ever develop. There is nothing medical science can do. In fact many more miscarriages are known about today - 50 years ago most women wouldn't even have known they were pregnant they would have thought they had a late heavy period.
If that's the case, sounds like a very peaceful solution for the world. The alternative is pushing for actual armed conflicts where actually working machines are killing actual people for corporate welfare.
