There are 260 million American adults. Already 12 million receiving a vaccine. Approaching 1,000,000 per day receiving first dose. At that rate we’ll need 118 days to have half the population vaccinated with a first dose in mid-May and the second dose in early/mid-June.

Python has a battle-tested, humongous standard library, and a rich ecosystem. It is easy to learn and it's great at gluing every day stuff. Data scientists like it, engineers like it, even the cashier at Lidl likes it.

I can see how Julia may challenge Python for academic use, but challenging Python in 2021 for industrial use is no joke.

I still can't get my head wrapped around the complaint that the developer program costs $100/yr, as though this were some great barrier to entry. To put it in perspective, I subscribe to <deep breath> Prime, Netflix, Hulu, Disney+, HBO Now, Apple One, Office365, PS+, and Xbox Live, and that's just off the top of my head. Most of them are for purely-optional entertainment, and all of them cost more money than the developer program. I suspect most people who frequent this board pay for several of these too. In comparison, the $100/yr for the developer program is not a lot of money. It's certainly comparable with other optional digital services. It's less than a single restaurant lunch per month.

You can complain that it's not right to charge for the program, but the developer program has a cover charge to keep out the riff raff. I don't think this is a bad thing. We all know how much junk is in the App Store as it is, and how long it takes to get a review. Imagine if they didn't charge for the opportunity to submit apps? How much soon-abandoned junk would suddenly appear, and how long would it take for proper apps to get approved?
I guess that's a chicken-egg question. What comes first: a polarized populace or free news?

People who polarize are seen and heard a lot: they use free news articles on social media to spread their perspective to as many as possible, triggering a counter reaction on the other direction, also influencing the journalists because they get clicks.

How wonderful it would be if none of that was free so people had to pay to read whatever has been spread. The blast radius would be limited.

My gut feeling is that 80% of the world are not interested in using news instrumentally to force political views on others. They may get caught up into it, but wouldn't if they weren't continously confronted with it.

It's the age old rule that 95% on internet communities lurk, and 5% post content. The 5% are more insane than average. :-)

Today in 2021 people are USED to seeing free news on social media. But that's just the current status quo. Imagine a society where people did not see or share stuff like that, as seldom as people share music or tv-shows or other kinds of content? There is nothing special with "news". It just happened to be the thing that's free and constructed to make people emotional and angry.

If there were only subscription services not competing with free, I think people would buy something that's as neutral and unbiased as possible.
Exactly. The system favors, even actively promotes, certain dynamics which lead to predictable results. I have faith in humanity though. They will eventually, slowly, converge on a new optimum. Probably under the stress of painful and certain extinction, but that's just a detail.

This also happens with work-related messengers and calls.

After transitioning to remote work during lockdown, chat&calls suddenly become mandatory to look at ASAP. Now I sometimes get multiple urgend messages while beeing on a surprising call. In the office, these people would see that I'm busy and wait. Now I have to line them up and prioritize them myself..

It took me a while to figure out that a few hours of this process could ruin a full day of productivity + requires much more mental work to regenerate after.

I do have ADHD though - so this is one of my biggest issues even under normal circumstances.

I’m sure to get downvotes, but some unsolicited writing feedback to help with readers: a (en) dash with no space joins two or more words (or signifies a range). This is different than an em dash that acts like parentheses. Ex: mother-of-the-bride is a single concept, like post-apocalyptic. I couldn’t parse your comment, getting stuck wondering what a “skim-yes” is supposed to be, and wondering if it was similar to a “skim-through.” A space around the dashes or using an em dash would make it much clearer. Cheers.
A possibly similar story:

I sometimes play video games on Steam under Linux. Recently I bought a new CPU (based on Zen3) and one of the games - Dirt Rally - started segfaulting.

After a quick fight with attaching strace to a running process under Steam (it was crashing v. quickly, so some racy script was needed), it turned out it crashes with

SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_PKUERR, si_addr=0x7ff88440e7b8}

A quick session with kernel sources, revealed it's about Memory Protection Keys (this causes SEGV_PKUERR), which seemed like something that game was not using at all, because it's quite a new feature. After another hour or two, I found out what was the cause. The game was mmaping a PROT_EXEC memory segment without the PROT_READ flag, and was trying to read something from there with a 'mov' assembler instruction.

mprotect(0x7ff884400000, 139264, PROT_EXEC) = 0

And under older i386/x86-64 CPUs it implicitly means PROT_EXEC|PROT_READ, because there is no way to make something executable, but readable. Under newer CPUs, the Linux kernel uses Memory Protection Keys to make the memory region actually executable-only.

After creating a quick'n'dirty LD_PRELOAD'able lib, the problem went away. Though, I wonder about Linus Torvald's mantra here, that the Linux kernel shouldn't break the userspace :)

$ cat game.c
#include <sys/mman.h>
#include <unistd.h>
#include <sys/syscall.h>

int mprotect(void *addr, size_t len, int prot) {
if (prot == PROT_EXEC) {
prot |= PROT_READ;
}
return syscall(__NR_mprotect, addr, len, prot);
}
$ gcc game.c -shared -o game.so
$ LD_PRELOAD=./game.so steam
Except it isn't. We obviously had setups that mirrored production long before docker and CI/CD became a thing, but spending time configuring those things, for every project is just insane.

Even pythons virtual environments take less time to use than .NET.

Sure I actually liked the "double click" thing in Visual Studio, but that had nothing to do with "if it works on my computer", it simply saved bundles of time because we'd publish every project to the same damn IIS instance and not have them all run their independant web-servers with their independant setups.

Hell we still put things behind the same damn IIS instance and it's load balancer and all that, because why wouldn't we? We're not Netflix, we don't need to scale to two billion people. Our max load is 50.000 concurrent users, yet our build load and our deployment pipeline is now so best-practice, SOLIDVOLID, Buzzworded, CONSOLELIEK and complicated might actually work for Netflix with enough iron.

What's worse is that, it's now your job. Not the operations dude who actually specialize in this, no yours, along with keeping up with you know, actual programming.

Being the public sector, we benchmark everything, and the things we don't benchmark we hire E&Y to benchmark, and you know what our most expensive resource has seen the biggest increase of their time going into over the past 30 years? Configuring and maintaining their tooling. Not developing new things that are useful for our actual business, no sir, but working with the tools that allow them to develop things. It's up by 130% compared to 1998.

I'm not sure what you'd call that inside big-tech, but in non-tech, we tend to call that, a waste of resources.

At least we can lower the cost by vendor-lock-in with azure, right?

I agree that dedicated news services could provide higher quality content in their domain. However, one thing I enjoy about monolithic news sources is being exposed to stories and happenings I might otherwise not know about. That's what I enjoy about HN vs. reddit - on reddit you explicitly subscribe to content you know you like, but on HN I find content that I like that I otherwise wouldn't have found.

Let me set the scene for you. It's morning, you know that by the time you go to sleep tonight you won't have another day. You had no prior knowledge that today was going to be the last day, and it can only last as long as the length of your average day. What do you do?

Honestly, given how much power big foreign companies have in many countries, I started to realize that China and to some extent Russia was right from the beginning to not allow unloyal competition from the big tech giants. For example Germany have zero benefits for letting Google, Amazon, Facebook and co. to drain profit and suffocate local competition while not paying any taxes or creating any meaningful jobs here.

I wish Germany, France and the rest of EU would just push for more regulations and taxation of foreign digital companies, even if that would mean having a Great EU firewall.

Remember, even the USA would not be there where it is now if they agreed to the free trade agreement with the UK back in the time after gaining the independence. They would be just a source of cheep beef and wheat for UK overlords.
It still baffles me that GPT turned out to be more than a glorified markov chain text generator. It seems we’ve actually made it create a model of the world to some degree.

Because of orbital mechanics, anything that would be traveling faster than the scaffold would be at a higher orbit and wouldn't be able to be caught.

The exception to this would be if the object were in an elliptical orbit, which would allow for contact to be made with the scaffold at its perigee, which be impossibly rare.

> Apple tho wants macOS developers (and users prefer apps from people dedicated to macOS).

This is a very strange argument to make in the context of Safari Web Extensions. Safari already had its own Apple-specific app extensions API, but it seems that Apple decided this was not sufficient, so they implemented the cross-platform WebExtensions API too. Clearly Apple is trying to recruit non-Mac developers with their command-line conversion tool for existing Chrome and Firefox extensions, and automatic generation of a Mac app wrapper.

If Mac developers were sufficient for this purpose, then WebExtensions support would not have needed to be added to Safari at all.

Why "deorbiting"? Considering the cost of putting it there, wouldn't it be better to group the debris in a junkyard? Tell the jawas, maybe they're interested in managing it.
You could also use the array to store only the order, and regular FK relationships for membership. That way the referential integrity of the items is guaranteed, but the order is more of a "best effort" approach, as in that there my be members that have no defined order (default to putting them last or first), or there may be items in the order array that have been deleted (and can then be ignored)

This need to rewrite, of course, is what Julia is trying to avoid. My workflow is exactly the same, and I’d love to be able to write code in a high-level language like Python and then use that directly instead of having to rewrite.

However, in my case the reason for rewriting isn’t just performance, but also to be able to build compiled binaries. Julia aims to be as high-level as Python but faster - is there a language that’s as high-level as Python but AOT-compiled?
I do think there is something to this, but it's exceedingly difficult to communicate about the differences.

For example English is not my native language and even though I'm basically fluent as far as understanding any TV show or reading books goes, but I still notice it doesn't reach me as viscerally as speech in my native language. It's blunted, it's like touching things with gloves on. So there is some sort of vividness of ideas, but it's hard to describe.

I think people who claim they can visualize something don't actually pixel for pixel visualize it. I read about some study where these people only realized this when followup questions came. I think you can excite your neurons to represent the visual concept of a house without having to expend all the effort to actually create all the parts, decide on the color of window frames, all the small details.

Overall I'm torn. I guess there are differences and we should listen to descriptions like these. On the other hand, I also know how unreflective and un-introspective average people can be.
It's not ideal, but you can run the Synergy client executable (synergyc.exe) without admin rights. You lose the conveniences of having it auto-start and using the GUI configuration, but you still get all the functionality. You also can't use the installer, but you can just copy the Synergy directory from a working machine. You also need a MS C++ runtime DLL, but you can copy that too. I'm not in front of my computer at the moment. I'll edit/reply to this comment with details

For example, on my client/project-specific machine (where I don't have admin rights), I have a batch file (start-synergy.bat) that lives on my desktop with:

C:\Users\jdbernard\Synergy-1.12.0\synergyc.exe -name client-pc 192.168.1.120

The US navy videos it's hard to tell what these are.

The picture is so grainy, a lot of the interest comes from the vivid eyewitness accounts.

I have looked at some accounts, for example listened to Lex Fridman interview with one of the Navy pilots.

To me, I need a photographic evidence that isn't some blurry smudge. If you start going down the eyewitness testimony route then you get some evidence for saints/miracles and also ghosts that meets similar criteria.

The phenomena reported in eyewitness statements in the 60s-80s at least some seems possible to capture with satellite/phone camera. It's possible that UFOs more cautious now or government is surpressing this but I take the lack of clear photograpic evidence as a reason to update beliefs.
If you haven't hit a brick wall with python, it is just because you haven't run into the right problem. I was doing something that required lots of conditional operations on small matrices. The FFI into numpy's native library really bogged it down. I didn't have permission to install a compiler on that machine so I wrote it in vba in excel. It was 11x faster.

You should care.

Many countries exercise extraterritorial jurisdiction laws and go after people who break them, this includes the US. If they can reach you, they will prosecute you if they want.

Normally this applies to the states own citizens but they will target foreign citizens who have hurt the state (see Assange).

Spying, poaching, abuse of children and war crimes are where some of these extraterritorial laws are exercised.
On second thought, I'm not sure if we're capable of this. To my (weak) knowledge, all of these models seem to disregard time. They just wait their turn and spit out the number of sentences they were told to spit out in advance.

An active listener would have to understand when to interrupt, which means it would have to be trained on audio (or timed transcriptions.)

I did have a funny thought that you could do this for Indians with a video of an attractive person "head-bobbling" at various rates of speed, and periodically humming an encouraging note. It's so efficient to have a physical gesture that means "I (still) see, yes. You can tell that I'm getting confused when I stop doing this."
Wouldn't becoming part of Canada technically fulfil the "join America" goal and allow the Queen to be kept?
I'm curious if you would still say the amount of bail is irrelevant if it were a well-off person getting a $1,000 bail. For what it's worth, bail is supposed to set to an amount based in part on the person's wealth. So for two people ~~convicted~~ accused of identical crimes, where one has 10x the means of the other, the bails should be 10x different. It doesn't always happen that way of course, but it is part of the guidelines.
Oh that's easy.

A moral conclusion is baked into the formulation of the issue, that Bitcoin "wastes" energy, but it can be applied to almost anything: gold mining "wastes" energy, circulating hard currency "wastes" energy, social media "wastes" energy, any waste at all wastes energy

To my mind "Bitcoin is a problem" is a reductionist take on the larger environmental issue of reducing emissions, and it shortcuts the larger philosophical issue of whether and how we decide whether some particular use of energy is wrong or right

Perhaps a solution would be to make electricity for bitcoin mining alone more expensive, or by the same token, mandate subsidies for "good" uses, like food and medical production. Or would doing this cause unintended consequences worse than the original "problem" of Bitcoin?

But to my mind Bitcoin being a "waste" or bad is not yet established just by citing its admittedly massive scale of energy use

Julia uses modern compiler technology to achieve close to native performance. This is not just generating LLVM IR.
Julia also has it's own optimization system for language specific optimizations that LLVM struggle to do (due to language specific info getting lost in conversion to LLVM IR).

Google's V8 (js interpreter) also uses modern compiler tech but I think it is not as capable as LLVM optimization vise (I don't think it is designed to be).

Python will either adapt or perish. Even if it is not julia it would be a another language.
