This reminds me of a discussion I had with a younger sibling (10+ years) about high school homework.

I was shocked to hear from him and our parents how much homework he was assigned compared to myself at his age, and I couldn't help but wonder whether the ease with which this homework was assigned played a role.

In 'my day' homework involved handing in paperwork, which the teacher took home to grade over the weekend, along with that of 30+ fellow students.

In 'his day' homework involved filling in a web form within some shitty e-learning environment, or at worst uploading a document somewhere, which the teacher could either grade automatically in the former cases, or skim through on their laptop in the latter case.

Discussions surrounding this increase in homework often center around higher-level sociological/psychological factors, but I wonder how much of a role ease played in all this: if you can grade 30+ tests with a click of a button, perhaps it leads to more testing?
No, he did not take money from anyone.

The author talks about dreams, but dreams are just one aspect of the ICU mental experience. The line between dreams, hallucinations, and memories can collapse.

Delirium in intensive care units is extremely common, affecting up to 80% of some patient populations. It is the result of a combination of highly vulnerable patients, extremely stressful situations, abnormal biochemistry, and powerful pharmaceuticals. It is poorly understood.

This delirium can pose danger to staff and patient in hospital, and can have lasting cognitive impact on patients once they leave. PTSD-like symptoms are not uncommon and are certainly under-treated. Given how common delirium in ICUs is, most facilities have limited or no psychiatric staffing for ICU mental health support.

I spent three days in a coma as a result of hepatic encephalopathy, among other episodes related to end stage liver disease. Some day I'll write more about the experience. Incredibly vivid dreams are just one piece of it.

F-35: What The Pilots Say
Thank you for the questions.

1. Our throughput benchmark is designed to measure data transfer bandwidth, and the comparison point is RDMA writes. In the benchmark, eRPC at the server internally re-assembles request UDP frames into a buffer that is handed to the server in the request handler. The request handler does not re-touch this buffer, similarly to RDMA writes.

We haven't compared against RPC libraries that use fast userspace TCP. Userspace TCP is known to be a fair bit slower than RDMA, whereas eRPC aims for performance RDMA-like performance.

2. eRPC uses congestion control protocols (Timely or DCQCN) that have been deployed at large scale. The assumption is that other applications are also using some congestion control to keep switch queueing low, but we haven't tested co-existence with TCP yet.

3. 75 Gbps is achieved with one core, so there's no need to distribute load. We could insert this data into an in-memory key-value store, or persist it to NVM, and still get several tens of Gbps. The performance depends on computation-communication ratio, and we have tons of communication-intensive application

4. Packet loss in real datacenters is rare, and we can make it rarer with BDP flow control. Congestion control kicks in during packet loss, so we don't flood the network. Our packet loss experiment uses one connection, which is the worst case. An eRPC endpoint likely participates in many connections, most of which are uncongested.
We simply use the google timezone API to find the event’s local timezone, for physical events, then store UTC. For non-physical events, we store UTC based on the timezone of the user agent that made the request, taking into account daylight savings rules. On the extremely rare occasion that rules change between when the event was scheduled and when it takes place, we don’t have a system in place, so the time would have to be updated manually.

NOW... it gets even more interesting for recurring events. Does 11AM on Tue mean 11AM on Tue after daylight savings? How about events like Shabbat candle lighting times that depend on when the sun sets?

It took us a while to do all these. Does anyone know a good non-API solution to timezone calculations / shapefiles feed?
Not quite an option in my particular case. I'm moving cause my wife got a once-in-a-lifetime opportunity in Seattle, so being in Seattle is a requirement :)

Edit: typo.
"You can do everything right and still lose"

I remember the saying "You are entitled to your actions, but not the results" somewhere in Indian philosophy. Means you should always do your best but there is still no guarantee for the expected result.
Ask HN: Should I pick up Dart and Flutter for my next side-project?
I'm between using node.js & React.Native or Flutter. I don't like waisting time but if that's where things going then I'd like to learn. But Google already failed sometimes in making a technology very popular.
Go look at the "Show HN" posts for some of the biggest YC companies; this community doesn't like things, and water is wet.
I have a PhD in nuclear astrophysics, did a three years postdoc at Lawrence Livermore National Lab doing lattice QCD, and am 2/3rds of the way through a three year postdoc at Forschungszentrum Jülich, between Aachen and Cologne, Germany, continuing my lattice QCD stuff in pursuit of first-principles precision nuclear physics and applying lattice methods to the Hubbard model (a model of electrons hopping on spatial lattices) which likely has applications to graphene and potentially high-Tc superconductivity and other crazy materials.

I cannot find a 'real' (meaning permanent) job in my field. I applied to about 50 tenure-track university and college positions and staff scientist positions. I applied for early-career fellowships from the Royal Society, CNRS (France), the Helmholtz Gemeinschaft (Germany), among others. Almost everybody I know thinks it's crazy that I don't have a job yet, but nobody has the money to create one. So I'm moving to UMD for a 2 year non-tenure track Research Assistant Professor job to give me 2 more cracks at the job market.

Lattice field theory is a computational technique by which we can extract approximation-free, fully non-perturbative from quantum-mechanical theories (I've described it on HN in a variety of comments, see eg. https://news.ycombinator.com/item?id=15782932). We use an enormous amount of leadership-class computational power.

Physics is now very computational (even theory), and often works with data sets that make industrial 'big data' problems look like toys. I mean, one of our lattice QCD calculations produced hundreds and hundreds of terabytes of intermediate results. Data analysis, correlated analyses, and all sorts of things that were old hat for physicists suddenly became lucrative. And presumably it's a lot less soul-sucking than further "improving" high-speed trading.
Most likely because Grindr is primarily used for casual / anonymous same-sex encounters. Its users may be more susceptible to blackmail / extortion.

There are many users of the app who are not open about their lifestyle (“DL”)
This article was in the latest issue of Air & Space. There have been a number of articles that have ridiculed the F35 as a waste of time and money, but it is interesting to hear what the pilots think about the plane now that they are flying them.
Cingular had nothing to do with AT&T. SBC and Bell South (2 baby bells) were who had Cingular, SBC acquired AT&T and took the name in 2005.

It seems that the primary difference here is that ERNIE generates a different set of data for the masked LM task that BERT trains on. Rather than masking words arbitrarily it does some preprocessing with some tagging tool to identify segments that can be masked (my Chinese is rusty so this may not be totally accurate).

I believe the intuition here is that BERT somewhat expects words to be relatively distinct units of meaning since it masks words individually, but this assumption doesn't hold for Chinese where "words" (characters) are more frequently grouped together to form meaning. I feel this could be applied to English to a lesser extent though, curious if anyone has tried doing a similar thing.
I might not be getting it, didn’t the videos also feature a PDA like device which is basically how they saw the future of portability, which is not far from our smartphones I think.
Passenger trains tend to travel faster than freight, true. But 25 MPH? No. Not on major lines, anyway.

You can probably find statistics that give you a number that low (or even lower), but I think they include dwell time in yards, not just road time.

This aside is more speculative and significantly based on personal experience doing 2 green-field products for one employer, founding 3 startups, and doing some internal research projects at Google...

But what I've noticed is that aside from frequently co-occurring with creative work, depression and anxiety are frequently the trigger to finding a non-obvious solution and making forward progress. In other words, they're not just mental disorders; they're feelings that can give you useful signal about how to proceed next, if you listen very carefully to them. Anxiety is basically your emotional systems being hyper-engaged, such that you get an emotional response from nearly everything. Depression feels like the opposite, a deadening of your emotional senses, but oftentimes escaping the depression actually points the way to escaping your real-world problem. If you can imagine a future where you are not depressed (which if you've suffered clinical depression is actually quite difficult), very likely that's a strong signal that that's what you should actually be doing, no matter how weird or unreasonable it sounds.

There's some evidence for this hypothesis here (2009):

https://www.scientificamerican.com/article/depressions-evolu...

You could also think of the anxiety related to creative work in relation to System 1 of the brain in Daniel Kahneman's Thinking Fast and Slow. In highly ambiguous circumstances (which basically all creative work is), it makes sense for your brain to become hypersensitive to all available stimuli, and to quickly pattern-match on a course of action without too much rational consideration. We experience that sort of emotional overload as anxiety.
Cool, morality determined by ad revenue opportunities.

What could go wrong?

Clearly nobody is going to shed any tears over Nazis... but is it wrong to support Palestinian claims to Jerusalem? Where's the line?

I don't like this move since I feel it will just push people into places where we can't determine real identification, should that be needed after a crime.

I don't like this move because I don't, fundamentally, think we should all have to agree with Zuck to have a voice online.

I don't like this move because it's reactionary, and there's no consistent philosophy behind why these groups would be banned but not others.

Just feels skeezy to censor people, no matter how skeezy those people are.
I am unclear how biased or factual this account is but it really seems negligent to accept this current process.

I have seen far less critical processes with far more safety checks and redundancy in place to minimize human error.
I’m not walking down any slope as I haven’t said anyone should or shouldn’t be allowed to do anything. You said white supremacy “isn’t even remotely like ISIS” and that people only think that because they “haven’t spent the time understanding” so here I am trying to understand.

So far I’m pretty unconvinced.

Anyway... these appear pretty prescient. However given technologies available in 1993, I actually find almost all of these pretty laughable as examples.

Would’ve been cool if it were made in 1973 though.
Other dating apps also allow users to state their sexual preferences, so although Grindr might have a higher density of potential blackmail material, they're not even guaranteed to have the largest collection. There must be something else that sets them apart from others. (Maybe they were the first to be acquired by a Chinese company?)
No, it means that while you can cheer this decision today, how do you know it won’t be used against you in the future? Or if the decision maker sensed your intentions or sarcasm or if you don’t beleive your speech to be hateful but someone else does.

The whole point of defending speech you don’t agree with is it promises that arbitrary rules won’t be used when YOUR speech runs afoul or someone else’s feelings.

Let me phrase it to you like this... if Mark Zuckerburg who you may generally agree with leaves Facebook and is replaced by let’s say Donald Trump and his assistant Mike Pence; do you still think it should be Facebook as a service provider’s policy to gauge what offensive speech is?

Maybe it’s not Facebook’s job to ban legal things you personally don’t agree with.

Ez, ez gara. Maybe, 100 years ago, but the Basque Nationalism shifted away from the alleged far right, traditionalistic and outdated politics (Sabino Arana) to the cultural, civic, values related nationalism about 70 years ago. Call us chauvinistic, but not racist, because even Black people speak better Euskara here than most non-Basque Spaniards.

And, OFC, they are considered as Basque as anyone else.

I didn't say that Linear Algebra and Matrix Theory were separated. I said that Matrix theory hit me like a ton of bricks. I took Linear Algebra in college prior to that, obviously.

I further stated that I think Linear algebra might benefit students if taught earlier, in high school.
The first line of the article reads:

... Chinese gaming company Beijing Kunlun Tech Co Ltd is
seeking to sell Grindr LLC, the popular gay dating app it has
owned since 2016.

So what's the point here? The Chinese gaming company has already owned it for over 2 years and have access to the data already.
Australia's lawmakers just need to amend the law so that it doesn't matter where the data is stored, as long as the company operates within their nation's borders.

I'd like to see how the Australian government handles things when MS cancels all their Windows and Office licenses.
The proper solution would be not to collect personal data, especially if it is not necessary for functioning of the app, rather than worry about who is going to buy the company.

You clearly have done answer in mind since you've already conceded the core argument. Who do you think? I'm good with the discourse between the public and Facebook leadership in so far as it targets widespread social norms and ignores the few loudmouths.

Feel compelled to add: I think we want the same thing, eg informed legislators. But from what I've seen, administrators run circles around legislators and their staff. Which is why I flipped on term limits (now oppose) and think legislators need a lot more staff.
This actually seems like the right use-case for SSHFP records. They allow for storing the SSH key fingerprint in a DNSSEC secured zone.

Normally this is considered rather weak, because of the reliance on DNSSEC. However, in this case I think its a very easy to take step that'll be miles better than just trusting everything.

The stronger alternative is Certificate-based SSH, but that is a lot of hassle. As it requires setting up a CA, handling revocation, and actually distributing the certificates.

Total non sequitur, low effort post. The mods are really showing their bias in this thread.

People respond with their best arguments when they are confronted with bad ideas.

People respond with censorship attempts and violence when they are scared that their own positions are weak.
I like it! They should apply this to the problem of TOFU in HSTS. For many HTTPS sites it's trivial to hijack them by getting a user to switch to a different device, as the devices' apps often don't synchronize HSTS databases.
Some of these social benefits can also be had at your local library, without the fees. It's nice to just go pull up a desk in the library alongside students studying for exams, curious readers curled up in comfortable chairs, and professionals working on their latest reports. It's especially nice when the library has separate areas for quiet, focused work and open discussions.
They have shown a remarkable ability to survive complete paradigm changes, keep growing and stay profitable. The FAANGs still have to prove that.
(CTO, not front-end dev so will answer more on philosophy and strategy than nuts & bolts)

We recently upgraded our B2C website, which is a SPA/vue affair. After going through the development and upgrade of the site, and seeing first-hand what the code looks like after having to do some debugging in it, I will clearly keep the SPA/js hammer in the tool drawer unless I have a very specific nail to hit.

Our next project, which is a back-office/CRUD app, will be Django or flask with a sprinkling of vanilla js (maybe some jquery to make things easier) and plain, honest html. I expect the experience to be quite less eventful than building a SPA.

To answer the rest of the questions, some reasons for this: dev time per page seems higher with SPA (of course the fact that I talk about pages is a hint that SPA may not be the right fit); harder to reason about when what bit of page is displayed how; and cold sweats every time I look at the length of package.json (it may very well be that we don’t do things The Right Way, but The Right Way is easier with classical frameworks)
My very naïve understanding is that in the keybase model there's no master, just several keys which can sign each other, so you can lose any of the keys (as long as it's not all of them), unlike in the PGP model, where you can't lose the master.

In practice, though, as long as you protect the master key appropriately, the PGP model isn't that much worse (and possibly in some ways better — I'm not sure what happens in the keybase model when one of your devices is compromised, rather than just lost, and you don't notice for a while).
You can definitely still implement policies that help a given group if on the whole you are not discriminating against other groups. The alternative is to force companies to group announcements so that they are not only equitable on the whole, but at every given point in time with respect to every other point in time.

Keep in mind that we're talking about China. If Apple pulls out, there's no shortage of Chinese companies that the Chinese government is buddy-buddy with who will happily go all-in on spying on consumers.

Apple obeys Chinese regulations, but it's reasonable to assume (based on their actions in the US) that they don't enjoy it. Which means they're not going to go out of their way to give the Chinese government more than they need to. This is potentially in contrast with the Chinese technology companies who would be more than happy to provide extra data to the government.

Apple is able to hold their position in China only because they comply with regulations, but in so doing they provide consumers with a better option than going through any of the Chinese government-friendly companies. Yes, it sucks that they have to comply, but in a scenario where Apple either chooses or is forced to withdraw from China it is the Chinese consumers who will suffer the most, because they will be left with only government-friendly alternatives.
Who could have guessed that laws which turn encryption into a legal quagmire in Auatralia would make companies that do encryption things less interested in working in Australia ...
You literally have the right to go stand on an actual soapbox outside your government offices and yell at people. That's what's constitutionally protected.

No one has to pay attention though.
I like your idea that "neutral might not exist." FB is going about this in the obvious control-oriented strategy: we have a problem, ok, we'll make a rule against it. This doesn't work, and can only lead FB to having lots of rules and everyone unhappy with them.

The problem with FB is that they have built a system that rewards polarizing opinions. Edward Deming said that your system is perfectly set up to give you the results you are getting, so if you want different ones, you need to change your system. Incentivize quality, disincentivize "viral-ness". Maybe limit viral-ness. Optimize for something besides addictiveness^Wengagement. Admit that people think, say, and do harmful things and build a system that is robust to it. Add some kind of negative feedback for posts.
