The issue we have is that the cutover is super hard to do in a zero-downtime way because we almost always have active connections and you can’t have multiple primaries. There’s tricks like read connections on the replicas but it’s still really hard to coordinate.

Given that Postgres has built in synchronous replication, I feel like it should also have some support for multiple primaries (during a cutover window) to allow better HA support
> Wouldn't the average teenager just stay up even longer? It's not like they are hardcoded to wake up at a certain clock time.

Additionally, what about the teens who do get up early? I feel like these studies are sometimes trying to explain something that really is simple to understand. Kids stay up later today because there is so much more keeping them awake. If they stay up late, then they need to sleep later to get the sleep they need.

Growing up, my friends and a I almost all got up with the sun. All the activities we wanted to do revolved around the daytime. As a consequence we were usually asleep not much later than 10pm.

I have an iPod and iPhone 4S as my main devices.

The iPod has excellent battery life, and I've upgraded it with an iFlash SD adaptor. The iPhone 4S has a small screen, and removable battery on a Third Rail case.

I had a quick look last week after the iPhone SE was discontinued. The highest small-screen (3.5") resolution is the iPhone 4 display (960x640). It's even higher than newer phones, according to dpi.lv. The best Raspberry Pi screen is 320x640.

What we as hobbyists need is a 3.5" RPi touchscreen module with higher resolution. Then the iPod modding community can provide a case, and Seeed can provide a phone. The problem is, I couldn't find anybody manufacturing high-res small size touchscreens.

And yet we also gained a lot of value we did not expect, such as the World Wide Web.

You cannot predict the true value of basic research in a straight forward manner so let’s just stop. This is about extending our understanding of the universe. We will find ways to use that knowledge and ways to enrich our lives because of it in due course of time.
I, and I assume most guys (and gals) in their puberty were horny most of the time, but my being a night owl I don't think factored into that at all. I studied much better at night, I was a lot more creative (music mostly) at night, and everything was more peaceful at night. I was horny too, I guess, but that was more of a 24/7 thing.
It’s just a scale of sensory and/or motor function and not very scientific. Genitals have very weak motor ability and very crude sensory resolution, so why would they be large on this scale?

I've been living in Asia for 24 years, working on R&D policy for the last 10, and have seen lots of countries come up with schemes to attract foreign talent, without coming up for ways to keep the talent in the country once the fad for whatever-tech has ended. In Singapore, for example, there was a huge push for biotech/biomed R&D focused on the ASTAR research complex. After a few years though, the government's interest diminished significantly (along with funds) due to a combination of 1) the political demise of ASTAR's champion in the bureaucracy (due in part to a feud with the daughter of Lee Kuan Yew; 2) the successful luring of global biopharm companies to set up Asia HQs in Singapore, which was viewed by some in the Sing govt as a 'Mission Accomplished' moment; and 3) the dramatic financial success of the Marina Bay Sands casino, which made a striking counterpoint to the vague, serendipity-based rationale for investing in basic research with no business plan in place.

Many countries want the cultural cachet and revenue potential that are historically associated with big investments in basic science. But smaller countries (meaning anything smaller than, say, Germany or S Korea) are going to have a hard time justifying the massive spending without clear economic outputs.

I think this applies equally to nascent tech sectors, like AI – maybe even more so for big data-intensive fields like AI. What does being based in Singapore have to offer an AI researcher compared to being in a major US or PRC city? Granted, the SE Asia location with a good hub airport is nice, but is there some advantage to your work from being geographically present in a city-state of ~5 million people? The odds are that this proposition appeals mainly to people who are 1) from the developing world, 2) who have a hard time competing in the developed world (for whatever reason), or 3) very senior scientists looking to pad their retirement income through highly paid advisory work.

All this can be well and good for people who go in with the clear intent to leave within 3–5 years. But some people find themselves wanting to stay, and once the funds for their chosen field of endeavor dry up due to the short attention spans associated with bureaucratic funding commitments, they may find that the welcome has worn out uncomfortably quickly.
You couldn't do much of anything at night with stone-age lighting technology. Sneaking around at night would be more likely to net you a tryst with a nearby tree branch or ditch than an exciting sexual encounter.
A few responses here highlight a very common problem in science: namely that people don't appreciate negative results as much as positive ones.

We've generally bemoaned (forgive me for not bothering to find examples but they're there) how difficult it is to get negative results published in scientific journals but we're exhibiting exactly the same attitude that leads to this in many comments here.
Thank you, it does look good.

Mozilla's answer is clearly some PR attempt again. Anyone with basic technical understanding knows that any form of communication includes ways ot identifying and tracking.

The dishonesty of silently installing telemetry to monitor people who disable telemetry is a telltale sign of this attitude.

Once again it is weakening the leftover trust in mozilla and pushes long time supporter away to alternatives such as waterfox. It raises the question again of mozilla " making far-reaching and very short-sighted decisions in a vacuum." taking control away from users, not respecting privacy and user choice.

Are you going to repeat this with every object that exists, or could exist?
Because there's always another type of 'elephant' to be thrown in. The networks are just not inherently robust against unexpected features (I'll call them outliers for want of a better term), and this is what needs to be fixed, and not increasing the variety and frequency of outliers.
Same here. I don't think it's a stretch to say that increased teen sexual energy, inextricably bound to increased general energy, was a big part of that, whether sexually active or not. In fact sublimated sexual desire/energy can be extremely helpful in creative endeavors. It's the essence of creativity, the creation of a new human life is pretty hard to top power-wise.

This happened to a company I co-founded. My common stock was bought at about 1/3 of the lowest price given to early employees for options. (I had RSUs, not options).

I got $130k, and their options were worthless.

Luckily the acquirer offered retention bonuses that helped dull the pain, but of course those are taxed at regular income and not long term capital gains.

Oh, and like a previous comment mentioned: the VCs have preferred stock so they get their investment back 100% before any common stock sees a penny. If employees had the same stock as VCs, I estimate I would have walked away with about $400k.
This study shows something more fundamental about the way that neural networks process images, other than just that random elephants are a problem. Rather than break the image down into constituent parts and reason about them individually, they use global context to help them classify. This lets them outperform humans on some tasks. The problem is if you show it something completely different to anything it has ever seen before (like a T-rex with a cane and monocle riding a bear), it will not reliably output something sensible.

To an extent it shows the gap between neural networks being able to classify things, and actually being able to understand what they are seeing, which will always limit their utility beyond classifying images that look like other images they've seen before.
A better workaround to this mess is to switch from firefox to waterfox: https://www.waterfoxproject.org/

I guess some of this is also, to what level do you need to learn German? Some of the parts of German grammar that are difficult for English speakers can be mostly avoided by just phrasing things differently. Basic use of cases is necessary, but some of the rules around compound sentences can be skipped at first by just using simpler sentences. If what you're after is a reasonable conversational/email level of German, that's enough for many things, and you can always learn more constructs later. If you want to be a professor in the humanities and need to write/speak a formal academic level of German, that's different, but that's probably not the common case for HN readers.

Don't get me wrong - CT is a super handy thing to learn, and it pops up a ton when thinking about any software, including type checkers and compilers, but the OP was specifically asking about type theory and programming language implementation. Yes, you can express lots of category theory in terms of type theory (the dream is to implement all of it in terms of TT so that we can mechanise it), but it won't be the best use of your time if you want to build a type system.

You mistaken, the issue is not about extension or core, the issue is that they specifically added code to track and monitor people who expressedly choose not to be tracked or monitored by mozilla.

Nope. Open Source is a trademark precisely to avoid this sort of misuse. It's not a "what it means to whomever" sort of deal.

That was done in part due to intentional (and damaging, if ultimately unsuccessful) efforts to undermine the meaning of terms like 'Free Software' by Microsoft back when the FSF was a fledgling movement and Microsoft was an evil empire.

I don't mean to imply negative things about the company. The license is still a heck of a lot better than fully proprietary -- I love the product in part for that reason -- but it's definitely not 'open source' or 'free software' as the headline implies.

(I don't think the company claims it is either)
I agree with this as well. No matter how hard I tried, I could not fall asleep early enough to get a decent nights sleep before having to be back at school in the morning. "Just go to bed earlier" and all of the other unhelpful suggestions lofted my way did not solve the problem. As a result, I suffered greatly with chronic fatigue throughout high school and beyond.

Had I been able to sleep properly during those years, I might be a completely different person now.

To this day, I cannot (and will not) work a Monday-Friday 8-5 job.

[I agree that the proof will probably not check out.]
LHC discovered the first known scalar particle, and the linchpin to the mass-generation mechanism of the Standard Model.

Yes, it turned out where other experiments had begun to hint that it might be, but I can state from personal professional experience that, prior to LHC, nobody really knew what to expect. Furthermore, most of those experiments were done after LHC began construction.

I would have bet on a single low-mass Higgs, had I been asked, only because it was the Standard Model prediction, but I would not have bet very much. I think most people expected something Higgs-like, but slightly different. I think everyone is surprised that there have been no surprises (hence this very article).

The very absence of surprises is perhaps the most important result from LHC. There were lots of good reasons to expect new stuff at a few TeV, and for some reason, those reasons just weren't good enough.

Viewed another way, if we hadn't built LHC, physicists would have continued to clamor to build something very akin to LHC until something LHC-like was built. It represented the most effort- and cost-efficient approach to the best predictions we could muster!

A collider, probably lepton/anti-lepton, that sits on the Higgs resonance is the clear next step, now that the Higgs mass is known, just as it has been since the "discovery machine" LHC was proposed.

Yup, lots of people are under the impression that you need to prove everything when it comes to DTs. That's not true - you can indeed push these checks to runtime, and just have the compiler make ensure you do it.

I don't think you should be downvoted, but there are parts missing to your comment. Teenagers have more distractions than ever, so it's easier to stay awake later. Teenagers also do less exercise than they have in the past. Just going outside and running around with friends is often a thing of the past.

Whenever someone tells me they have a hard time going to sleep, my first question is always to ask if they exercise. I rarely stayed up past 10pm, much less past midnight as a teenager because my friends and I were getting up early to surf, ski, skate, play football, basketball, baseball, etc... By the time 10pm rolled around I was dead tired and ready to sleep. And on days I had to work after school, I got home around 10 and would literally pass out.

I know the environment is different, but my experiences make me cautious to say 'all teenagers' have different rhythms or want to stay up all night because of something biological.
As a new entrant in this space, I don’t see an issue with Apple being cautious and sticking to non-controversial content.

But there are several ways to tastefully include sex and nudity to add to the artistic value of the work without compromising its brand. The same goes with violence, drugs, politics, etc. The English speaking world may be fine with this. But this decision could possibly end up being an impediment to getting more creators and in turn making more money if Apple wants to get into local content beyond English and beyond that world.

Different people in cultures may have slightly different views on the well known characterization of porn as “I know it when I see it” (by Alan Novak/Justice Potter Stewart), but what matters more is whether the content fits the context (or sets the context) and is useful to carry the story along. Even people who are more conservative in their views of sex and nudity can distinctly evaluate/classify pornographic movies from non-pornographic movies.
Or just look at the commit history.
ESR means you usually have a little time before the next nonsense hits you, though it was not the case for dropping alsa in favor of only pulseaudio.
To be fair, the "true origin" story is a little misleading. A bunch of douchebags wanted credit for Stallman's work and basically threw an underhanded hissy-cow to try to undermine him to co-opt his position. There was a pile of exaggerated (or often fabricated) stories thrown at the FSF. Commercial players came in to support the attack with a whole range of motives -- from wanting something more corporate to an "arm both sides" mentality to undercut the movement.

While I agree with your point, I'm not sure the alleged history supports it very well. It's a pretty ugly piece of the movement's history.

Now, that was two decades ago, those people are gone, and OSI is a very nice, good, and friendly organization today.

I still remember when I started playing around with computers, 40 years ago in a Tandy store on TRS-80, you were told something like "it doesn't matter what you do on the computer, you can't hurt it or damage anything". Now everyday when I work (on networking and security for large enterprises) I constantly am thinking about how I have to really make sure the process I am about to execute isn't going to break something or disrupt someone's business operation. Rarely do I have to contemplate that what I get wrong might kill someone though!

Being a startup is not about size, length of existence or turnover.

> The trouble is that in most programs I want to catch most exceptions very near the top ("main" function), not in the calling function immediately above where the exception is thrown. In other words the check is useless and done in the wrong place

It's been a while since I've done any Java, but I seem to remember that you can just annotate your function with the "throws" keyword to propagate exceptions up the call stack, so that you can handle them somewhere else.
Eh, when the rest of society sleeps who you promised to wait because nobody wants to pay screw you money.
