Most MOOCs I've encountered are targeted at a higher age-range than 3-18.
Lots of people here obviously also think this, but I maintain that they're wrong. Consider what the Wired article you linked actually says:

> In a 1993 study, he found that hand-eye coordination deteriorated immediately after a player's first drink, but balance and accuracy improved at a BAC of 0.02 (beyond that, performance fell off).

A BAC of 0.02 is like, I dunno, less than half a beer? (And even then the article suggests a mixed bag.) I have no trouble believing that very small doses of alcohol could relax the imbiber in a way that's useful. But I suspect most of the people here who think I'm wrong are referring to larger doses not measured in fractions-of-a-single-beer.

And, again, I very much doubt it.

Your ability to do almost anything falls off beyond the 0.02 point mentioned in the article. What's actually on display here is that people are very bad at evaluating how alcohol affects them. None of the claims here would survive unbiased testing.
Where were you working? Or maybe you can say a list of similar places if you don’t want to be specific
> 3G are okay now

Is it really?

AT&T and Verizon, two of the largest mobile data conglomerates in the US, have stated their intentions to shut down 3G service in favor of 5G by February 2021 and December 2020 respectively.

Elon Musk Reveals Plans for His Million-Mile Battery
The reason why Facebook bought Giphy is not the Gifs themselves, it's the data. So I would say the privacy of search data and context would be the number one concern for anyone. It's pretty hard to find the balance between privacy, trending content, and relatable content, but it's for you to tune the knobs.

Also, if you release the API, I'd say making it a drop-in replacement for Giphy would increase the adoption. S3-compatible storage options, or Fixer-compatible APIs, etc are examples and they can help reduce the friction.
Especially in super-budget builds. The extra $30 that you save by getting a reasonably good cooler with your CPU versus needing to replace the stock Intel one can be huge for someone building in the $500 range.
Dreams Upended: Layoffs Shatter Tech Boom
Actually, I read a rumor somewhere that was planned for Windows 10 as part of UWP, which already supports JS apps.

They've already gone fairly far in integrating PWAs with the new Edgeium, so we'll see where this goes. (Your installed PWAs appear in the control panel for uninstallation, for example, which even Chrome doesn't do yet.)
Yes, the number of L1 fill buffers was static at ~10 for almost a decade, and this, in combination with memory latency which didn't move much, proved the limit on single-core bandwidth.

That said, in ICL there has been a nice jump.

Graviton results to RAM certainly are nice. I've heard that in this type of store workload they can automatically use something like NT stores, avoiding the RFO (which would normally cut bandwidth in half).

The Intel chips do get much better numbers if you use NT stores... but I didn't go into that since it wasn't the point of this article.
Alternative stores don't have the same access as play store. They can't have auto-updates.
We got sued in Australia by an American company for using a open-source PCB https://github.com/sparkfun/MaKeyMaKey .

The claims were under trade mark infringement (note SparkFun didn't sue us) and the PCB layout as "deceptively similar".

Thankfully we got our money back on insurance.

"releasing a new pandemic game"

Developed across the last 3 years? This seems like an inapt description of what OP described here.
We are planning in the next few weeks an overhauled persistence API. Among other things this will add the ability to provide a callback in `initializeState` rather than a value. However, this doesn't help if you need to do async work to retrieve the value. The way we generally think of SSR is that you get a single render pass and then you're done, no time for async work. So for hitting a database you want something like Relay that statically knows your data dependencies and can do a single request to initialize. It's true that there's some complexity there, but there are also great solutions to really hard problems. Recoil doesn't attempt to address that space.
Ask HN: How blind people can use the internet on desktop?
My father is blind, from the moment he was born, but blindness does not define his ambitions. He has a phone and a desktop, both equipped with screen reader applications (NVDA, JAWS, and Google TTS).

He has almost no problem using desktop apps, he can use certain mobile apps (touch, android), but he has problems using internet on his desktop (using internet in mobile phone is a big pain and of almost no use, if you don't know how disastrous it is...).

So my question is that how blind people can use internet, and what are the best workarounds?

Is there a certain sites that are helping with hot-keys and shortcuts?

How blind programmers/hackers do their job?
How did you cool them? I mean, didn’t you find stock fans way too weak especially had it been in a “quiet” PC?
I would imagine the group of people who immediately accepted everything this book claimed as fact and went on to immediately adjust their lifestyles to match may have a strong correlation with the group of people who are more susceptible to the placebo effect.

I didn't make it through the first chapter before I started looking into the accuracy of the claims he was making. Some of them were clearly bananas.
I think I’ve got some similar experience. I always had underlying focus issues, but managed to excel at school and first job because I really cared.

First work experiences led me to become pretty cynical about office life, and I find that my motivation ultimately gets sapped because I don’t think what I do is that important.

I’ve been soul searching for months about this, including trying a different workplace, etc. The thing is, I know any job can be meaningful—finding meaning in it is something I need to work on.

But I’ve also been searching for a path that will better suit my values.

Some conclusions:
I decided to go back to school, and I’m really good at focusing on school work now, it is much easier to do than making myself work.

I wonder if the school work is more motivating because there is the chance for graded feedback though. At work, you never get an A, just “good enough” or “not good enough” plus you don’t have the feeling of working towards a clear goal of the degree.

I wonder if your experience has some things in common with mine—maybe grad school was easier to focus on goal and progress, and start up you were fresh to work and excited.

I ultimately think I have to find some way to feel that what I do is important to the world. That by working on it, I’m creating something important. The question is how to get to that feeling!
In France that's the same for software. I had not realized that until my lab made me sign a very specific copyright sale contract.

Mathematical formulas are considered unpatentable and uncopyrightable and legally, programs have been recognized to be equivalent to mathematical formulas.

So only the formatting, variable name, decoration of code is the ground for copyright. My understanding is that if you were to run the code through an obfuscator, the result would be free of copyrightable items.

To my despair I never found anyone playful enough to help me explore how solid this reasoning was.
I can only vouch for post-Soviet states, but it's supposedly also widespread in India and China (and who knows where else). I think we inherited it from Soviet era when hard work and imitation of hard work would be compensated the same.
PID is popular because it has only three tunable parameters, and you can kind of just turn the knobs until it works. :-)

For a more systematic design, construct a simple mathematical model of your plant. If nothing else, this will allow you to run faster-than-realtime simulations to experiment with parameters. (Thermal time constants are typically annoyingly slow to fiddle with in real time.)

Simulink is an ideal tool for this, but you can just as well use Python or C++. One way to do it is to structure your model as a differential equation and then use a solver to integrate it.

There are several typical lines of attack. Write the plant either as a transfer function and then think about poles and zeros. Write it as coupled first-order linear differential equations and think about state space.

"Feedback systems: An intro for scientists and engineers" by Åstrom and Murray is a popular introductory text. "Feedback control of dynamic systems" by Franklin and Powell is a superb, slightly more advanced college textbook. (The current edition is wildly expensive but older editions are just as good and nearly free.) I also like "Control System Design: An Intro to State-Space Methods" by Friedland (an inexpensive paperback published by Dover).
There's already a popular `howdoi` that me and a buddy made:

Yeah, privacy for us has always been #1. It means we will need to monetise, but all indications are that teams are willing to pay a small amount for that privacy. We have the benefit of not wanting to get rich.

Significance of AI-Based Mental Healthcare Systems in Social Distancing Measures
I lived by most of these mantras for 20 years and when I turned 40 I decided it wasn't worth it. Literally on my birthday I said, "I'm going to stop acting like a jerk just to get things done, practice deeper empathy, smile more, and stop working 15 hours a day.

I can (and have) build a successful company without acting like there must be some maniacal focus that makes me abnormal.
Thank you! My hope is to be able to support as many platforms as we can, or even open up the API in way that allows users to roll their own.
When did it become acceptable to embed networked surveillance like Sentry into cryptographic tools? To me, that entirely defeats the purpose of end to end encryption.

Whether the key is generated on the server and provided to you, or generated on the client and potentially uploaded to the server due to embedded defect surveillance: that's simply not end to end encryption.
>> attempts to steer the ride-hailing giant through the coronavirus pandemic.

No doubt this is accelerating certain motivators, but I for one am a little sick of the "COVID Excuse" for blaming aspects of these non-business plans that were bad ideas without a global pandemic on which to blame them.
This becomes more significant when you consider that software binaries (not just source code, actual ones and zeros) are copyrightable. Copyleft licenses like GNU GPL make use of this by requiring distributors of binaries derived from other GPL works to also release the source code of those derived binaries to the public. However, in the hardware world you could take a open PCB design, modify it, and distribute the physical PCBs or use it in your products without having to publicly release the PCB schematics as well.

To wirelessly stream PC virtual reality games to the Oculus Quest you wouldn't just need Virtual Desktop but also a 5GHz wifi router.

You may be interested in the alternative (official) solution, which is not wireless but allows streaming PC VR games using "Oculus Link" using a compatible USBC cable. The cable that comes in the box is unfortunately USB2.0 (so not compatible), your best bet is to checkout this page: https://support.oculus.com/444256562873335/. The official Oculus cable has fibre-optic transceivers built in so is very expensive. Oculus lists some third-party cables on Amazon by Anker, which used by a lot of people (10 foot recommended, but the tiny 3 foot one is really cheap).

I haven't yet tried Virtual Desktop 5GHz streaming, but Oculus Link with a 3 foot cable streams perfectly (good for seated VR, which many PC games assume). I do want to try 5GHz Wifi streaming though! Untethered play is the best!
Instant boot is best described as suspend to ram but that is a pretty screen/battery life for the price.

I'm not convinced the security is notably better.
Copyright was originally set up to protect artistic works and not ideas or devices [1] [2]. Hardware in this context (PCBs etc.) is, I guess, considered an idea or device rather than a piece of artistic work. I think this is why we have the two systems of copyright and patents. Copyrights had the scope of artistic work and patents had the scope of engineering work.

I think one of the confusions is that we're so used to source code being copyrightable but that's a relatively recent invention when software came into mass use [3]. My opinion is that were it not for lobbying efforts to consider source code as artistic work, source code would probably be considered a "device" and not subject to copyright, just like hardware.

I don't want to put interpret Stallman's view incorrectly but I believe that this is the crux of his argument. If I interpret his view correctly, he believes software is more function than art, especially as it relates to fundamental infrastructure, and that copyright shouldn't be applied to such works or least should be restricted in the scope of application.

Also note that clothing is not copyrightable. This is why you see so many (legal) knock off clothes. The brand, or trademark, is something that's legally protected but not the designs themselves. I think the fashion industry is lobbying to try and change this and have their work protected by copyright [4].

IANAL

> I've heard someone say that PID is the deepest you can get without in control systems without advanced mathematics and I think hey might be right.

It's true that there is a lot of surprisingly deep math in control theory, but even learning just a little bit of the theory can be greatly illuminating.

The trouble with PID is that it is typically treated as a black box with three magic knobs that you twiddle until your system works. This can be very frustrating.

By contrast, by applying a little bit of theory, you will be able to calculate the PID gains and have your controller work the first time.
Insurance is a tax on everyone, and probably a tax on you specifically.

Even assuming that insurance companies act as naive rationalists believe they do, losses are socialized. In actual fact, insurance companies are able to price discriminate against policy holders likely to cost more than the average cost in the future, especially if likelihood of future losses are as public as court proceedings.
I love Termux. They must introduce a mode where a user can whitelist certain applications for this, get the permission policy inside the application.

You can do this from mobile (on Android, maybe Chrome on iOS?)

Go Share...-> Chrome (Print) --> (Brings up "Save to PDF" (!!)) --> Save to Drive (and then sync this drive to your computer).

You could also save to Dropbox or whatever other syncing service you choose.
Amazon often mixes inventory. As long as the SKU matches, a product from any supplier goes into the same "bin" and you buy whichever one is geographically closest to you.

Some bad actors will sell counterfeit products through Amazon to "launder" it. Other times, people will buy a real product and "return" it (sending a fake one back), which results in Amazon stocking it.

tl;dr Never shop on Amazon unless you have to. Best Buy, Target, NewEgg, MacMall, etc. tend to have similar prices and aren't as anti-consumer.

Another factor is that you very likely need some kind of web UI so there's a huge benefit in using web technologies across the board. Once again Apple music is a good example. They had to build a browser-based UI to keep up with the competition and once you've done that there is a strong incentive to reuse it.
Yikes. Is this meant to be used in a command line application? Or are you actually meant to call a function in your code that could crash your application on bad input?
None of the app stores are fair. Apple charges amazon 2x less for any subscriptions done through the app store. They all reject many indie apps for protecting privacy or security but then all the big apps are allowed to do it. Their apps can access system APIs that are off limit to others.

Some people in the comment section only recently feeling the censorship done by china affecting them but imagine other non-US countries that get censored by American companies all the time.
Well, yes, but this is a bit of a false dichotomy.

It’s obvious that capacity for discipline and work ethic are not entirely independent of genetic factors.
We are so used to the silliness that every data is copyrightable that we forgot how weird it actually is. No, there are things that are not copyrightable and this is actually the default.
- Use a proper IDE, and note a text editor with 45 plugins.

- Use strict typing whenever possible. PHP has scalar typing now, and TS for JS.

- Use static analyzers and bake them to your CI workflow.

- Unit tests.

- Test your unit tests with mutation tests.

Overall, non-sloppy code takes more time, and you'll often find yourself spending more time in tests and code architecture than writing the core code. But in the long term, it will save time. I'm refactoring a project I worked 6 years back, and the test suite brings tears to my eyes, looking how thorough it was, which made the code decoupled, ending up me spending just a few days to refactor it all!
yummy!! :)
I don't understand this... Lift and Grab aren't doing so bad. Also, things are opening back up again. Even their quarterly results looked very bad, it was already priced in and so no benefit there. This reduced focus basically just translates to much lower ambition and not a good thing for long term valuation. On the other hand money is super cheap. They could double on debt if they want to. I'm not sure what this layoff buys them anything except injuring their future prospects.
this is actually how I have my personal website. fairly easy in my opinion.

How to Scale an Application Security Program – Part Two – ReThink Security
The title is confusing because they talk about "layout" and "topologies" but it is just actually lithography masks that are protected by this treaty:

> (ii) 'layout-design (topography)' means the three-dimensional disposition, however expressed, of the elements, at least one of which is an active element, and of some or all of the interconnections of an integrated circuit, or such a three-dimensional disposition prepared for an integrated circuit intended for manufacture ...

So if you just express a schematics, with no actual placement, it is not copyrightable.

Normal literally means dead average and a lot of people use a lot of stereotypical behaviours to escape from that fat part of the 'normal' curve to varying degrees of success

Just like everyone is free to leave their power company and install solar panels, just like everyone can leave their water company and have water tankered in. Just like you can leave your telecom company and use satellite data.

Just because a company is providing value that doesn't mean that it shouldn't be regulated. Just because you can technically leave a service doesn't necessarily mean that you aren't realistically locked into it and that that service isn't going to exploit that fact.

I know about bioinformatics and the contributions of biology to computer science and vice versa. I've personally worked in both field sampling and data analysis. My overly offensive generalized statement was a light jab towards field biologists i've known, including my own friends who i've debated on this subject with, who tend to dislike computers and will go as far to avoid even excel and hand write their data while doing all math on a calculator. It really wasn't meant to be taken seriously and I suppose would go above the head of those who haven't spent a lot of time in the field with biologists.
Not me personally but a close friend I know that works there says morale is at an all time low understandably. Luckily he wasn't fired but a close coworker of his who was the #25th employee of Uber was removed. 6+ years at Uber and was managing and running a team that wasn't deemed essential to Uber core services apparently. Kind sucks but these people are at a position where it shouldn't be difficult to find another position elsewhere.
I am actually quite annoyed by this specific points, because I am sure users would certainly mind if someone told them that Slack and Spotify were taking two hours off of their battery life, and they'd certainly want something better than that if possible. The developers of Electron apps are largely shielded from outrage by user ignorance, and users blame their computer or themselves instead.
