This is similar to the problem of hiring new employees. Personally, I've learned that it's more important to hire some and see how they work out, as you really can't predict actual job performance and fit from most interviews. Sure, you can weed out some of the bad apples, but there are people who are politically disastrous to add to a small organization that seem like great hires initially. I now think that getting someone into a position quickly that seems like they have potential is more important than finding the perfect candidate. People will always surprise you: sometimes for worse, but sometimes for the better.
This post pairs nicely with Julia Evans’ post on why most people use the Linux kernel’s TCP/IP stack and why a few others would bother with a userland stack.

In her post she doesn’t mention fly.io’s motivation for doing userland TCP-IP: a nicer end user client experience.

If I read this correctly then fly.io did all this work to make their CLI user experience markedly better. That’s pretty cool. Twist yourself in interesting knots to make your user’s lives better, maybe even in ways they won’t notice!
If you look at two examples, they may have the same "architecture", but on one, more of the architectural blocks are on-chip, and on the other, less. I don't think what is on or off the chip really changes the architecture, though it would probably change the performance, and the pin boundaries do drive other system considerations. But otherwise, the architecture is the architecture, or am I looking at it wrong?
But Warner Media is still a small player compared to Amazon for example. I don't think they would close the TV channel, or even the concept of online streaming, but they may decide that it's more advantageous for them to merge with a competitor than try to support their own platform against giants that make 10x their revenue every year.

Agreed on Apple for now, but as much as I think it'll take a decade for Netflix to "fail", I think Apple is fine with taking a decade to take over the market with Apple TV.
Can't Apple close a developer account if it's never used to submit an app to the app store?
Can anyone explain these timelines better? Can we throw more money at this and scale much faster? Are safety/regulation considerations the main bottleneck?

This has gotta be one of the most important investments for humanity and our planet. Hard to fathom these timeline predictions in the same world where mRNA vaccines and various spacecraft have scaled in <1 year.
I have some questions about how access to Secure Enclave, and in particular hardware keys, would work in a sideloaded app. It would be tremendously helpful if someone knowledgeable here might be able to explain!

Wouldn't sideloading make it possible for one sideloaded app to somehow impersonate another sideloaded app, and thereby trick the PKA/SKP into signing a message with a private key that the imposter shouldn't have access to? And might we even see vulnerabilities whereby a slideloaded app could impersonate an app downloaded from the app store?

If there is no way to securely distinguish between two sideloaded apps, such that one app could impersonate another in getting access to OS- or hardware-level cryptographic services, then that could be a real problem, no? And if you have downloaded an app from a third-party app store, what is stopping that app from somehow getting access to OS resources that it could to use to impersonate another app?

Does anyone know how this issue is dealt with in MacOS?
Whenever I see this, it's never actually good news.
I was using SLIRP a few years ago to tunnel traffic through a cheap OpenVZ VPS, (for downloading Linux ISOs). I had to manually patch the TCP window size and recompile the binaries to get decent speed as the original code doesn't support TCP Window Size Scaling. I tried to upstream the patch to Debian but the maintainer wouldn't reply. It worked well enough but now I use wireguard.

Modified SLIRP code is also found in VirtualBox, Qemu, UML and other virtualization software, for sharing the host connection in NAT mode.
Netflix has first mover advantage, however, and I think that’s extremely valuable.

What do you mean by "the worst case for LSM trees"? I guess you could merge two index segments (SSTables, in Google-derived implementations) faster if their key ranges don't overlap, because you could just concatenate them without encoding and decoding their entire contents, but does anybody actually do that?

LSM trees are a lot faster than B+trees with lots of random writes.

In a by-the-book B+tree implementation that doesn't allow MVCC, if your branching factor is 1024, your table is 256 gigabytes, and your records are 128 bytes, most random record writes require updating four tree nodes, the transaction log, and the actual record page, which would be six random seeks without a writeback cache, and probably three random seeks with a writeback cache. I think in practice on modern SSDs this means three 4-KiB blocks added to the FTL's transaction log, but without further write amplification I think that fragments the FTL's storage so that reading a tree node requires multiple random page reads instead of one. If you use a log-structured B-tree approach so MVCC is convenient, you probably want to use a lower branching factor; say you use 128. Now your tree is 5 levels of internal nodes deep, and each node is, say, 2 KiB of data, so you're appending 10 KiB of tree data to the write log for each random write, plus the 128-byte record.

By contrast, with an LSM-tree, at the moment of commit, you just append the 128-byte updated record, perhaps after an in-RAM sort: 80 times less data. But if the data survives long enough, it eventually has to get merged up to the root through a series of merges, which involves reading it and writing it an additional logarithmic number of times. Say your merges are 8-way on average; in that case the data has to get read and written 11 more times before the table is a single 256-megabyte segment. That's still 7 times faster than the log-structured B-tree approach.

The difference gets bigger with spinning rust.

And that's why, on one machine I tested on, LevelDB could insert 300'000 key-value pairs per second while Postgres manages about 3000 and SQLite about 17000.
Aspect-ratio is great
OK, you will know better than I. But I wasn't overreacting. It seemed odd to me that literally 20 minutes after this was posted, there were a non-controversial response about possible contamination which had been downvoted enough to turn grey. That to me suggested an agenda.
Bowling Alone is a great book about the complete collapse of these sort of groups in America.

There is also serious mistrust of the Chinese government by the citizens of China. They just rarely communicate it as there is real risks to doing so.

It feels so bizarre to have someone convey seething hate for the government in private while seemingly being supportive in public. What is less obvious is how brittle it makes the country, it could literally dissolve into anarchy tomorrow or last for hundreds of years.

For those on macOS/iOS, using custom text expansions [0] also helps to do this without having to leave the doc you’re editing. I’ve built up tons of these over the years for things like ⌘ (“commandkey”) → (“rightarrow”) (╯°□°)╯︵ ┻━┻ (“tableflip”) and of course, a party parrot wave for Slack (“parrotwave” → :parrotwave1::parrotwave2::parrotwave3::parrotwave4::parrotwave5::parrotwave6::parrotwave7:). They can sync over iCloud and you can export/import them with plists.

I now want to add table characters like these, just need to come up with a good naming convention…

Thank you for the contribution, but the article doesn't seem to dive into the types of stats that would be necessary to answer the types of questions I asked. I will try and look deeper into some of the stats cited and their methology to get a better picture of their point of view though, thanks.
You are generalizing your stable situation and values far too much.

The population stats are something like 60% of men will be fathers but 90-95% of women will be mothers. Most women who can reproduce will but a huge percent of men who can will not.

40% of births are outside of marriage in the US.

I would think the only real generalization that can be made is that an introverted guy with money is more likely to get married.

I would bet money on that stat that women being the aggressor in Korea is simply not true in a statistical sense.

Screens have fixed this problem since Orwell wrote that in 1933.
Indeed, though in fairness, neither can a home gas range. Professional chefs will use extremely high powered burners that they control with their knees or thighs to manipulate the temperature. It's amazing to watch if you've ever seen it done. Home equipment will never get hot enough to match that kind of heat, gas or induction.

Automation will essentially keep the top percentiles of intelligence employed while everyone else suffers immensely. 80% of the country is going to be fucked in the coming decades while we automate everything. It's why UBI is so crucial in the future.
Microsemi has a new SoC that is based off their Polarfire FPGA series and includes a RISC-V core with a smaller FPGA fabric. Unfortunately they're rather expensive like virtually every other FPGA that has 10+Gbps capable SERDES.

What's your threshold for novelness?

We can't truly know just how novel covid-19 is; we don't have sequences from the database of coronaviruses, and even if we did it might have leaked right after it was collected, without having been sequenced yet.
The interesting part is that this sample sequence seems more ancient than the most ancient one made public by China so far.
I'm wildly uncomfortable with normalising the idea (that is far too normal already) that you owe your parents a thing for raising you.

We have a lot of choices in this life, but whether I get brought into it isn't one.

I have no expectations of what my son will or will not help me with in the future and will try as hard as possible to set him up well - because he didn't have a choice in his circumstance, I and solely I did.
Heads-up, if you still have a Minecraft (not Mojang) account, then you will need to log in with your username, not your e-mail address.
This stumped me for a bit when I just (successfully) resetted my password, which was then promptly rejected at login when I used my e-mail address as username.

Luckily I could guess my username...

If you are looking for a reason for your travails, here it is. If you started out with this level of contempt, it’s no wonder you’ve been unsuccessful. If you became embittered due to your challenges, then I’m sorry. That is a hard path. But if you want it to change, I think you have some work to do. And I wish you luck with it.
Hey thanks for the suggestion! :)
You know, I found Severian to be really interesting as a character. I wanted to see how he turned out and expected a lot of development... But the book falls kinda short.

I always tended to stick to Sci-fi but recently I found that I didn't dislike Fantasy as I thought (I love the books from Brandon Sanderson).

Regarding the obscure English: I _loved_ learning those words as I have a thing for old and obscure words, you should see the face of my friends when I speak on _proper Spanish_ but they can't get a thing hahah ;D

Have a nice one!
I think they could make that case, and I'd also love real Firefox, but if that happens it basically removes the last thing keeping “the web” from not meaning “whatever the Chrome developers choose”. There's approximately a 0% chance that all Google properties wouldn't start heavily pushing you to use Chrome or mysteriously developing odd performance or reliability issues in Safari.
> Can you imagine the power of a single monthly subscription that gave you immediate access to films, TV shows, music, video games, streamed live events, etc.? Do you think Netflix can match that with its proprietary approach? The company will be forced to open up its own system, or face inevitable decline, perhaps even obsolescence.

The author does not understand media distribution and has this exactly backwards. Netflix did want to be the single monthly subscription, but the content rightsholders would never allow it because it cedes all the distribution control to Netflix. The last good deal Netflix got was the Starz deal in 2008 when the studios still underestimated the future of streaming. After that it was a steady downward trend, and Netflix realized that as a middle man they had no future, so they entered a race to become HBO (by producing their own content) faster than HBO (and all the other major content rightsholders) could build their own distribution.

The idea that Netflix is somehow "proprietary", and the other examples from other industries are "open standards" is specious gobbledygook. You have to look at specifics. For instance, Netflix doesn't make devices, they integrate with smart TVs and OTT boxes which absolutely are open standards as much as any of the other examples. And even within the Netflix bubble they do license others content, so it's not all "proprietary", but on the other hand it's an app, not a platform, so you can't really compare it to a payments network or an operating system like Microsoft Windows—that is what Roku, Samsung and Apple provide, not Netflix.

The whole article is just another in a long tail of naive consumer complaints, decrying how things "should" be from their perspective, but in total ignorance of the incentives and systems that lead to things to being the way they actually are.

(full disclosure: I co-founded and led a streaming company from 2007-2016)
With OpenSCAD your script is the model - there are no mouse-based modeling tools like you might be used to with Blender or other 3D software. The closest comparison I can think of is if each of Blender's geometry nodes were a single line of code.

Never heard of anyone getting killed by the 230V power in Europe. A few people I know touched it and it does hurt.

Perhaps it's because all houses have residual current devices which trigger much faster than fuses if current leaks to earth (eg through a person).

I'm not sure it will persist as a streaming service for very long as competitors seem to have unlimited resources (Amazon, Apple). But it does a really good job at producing content globally, so I think it will persist as one of the major global production studios.
This unproven quote seems like a great justification for what they call “continuing the cycle of abuse”. Or what Calvin’s dad calls “building character”.
it's 230 (+-10%) nominal not 220. At my house it's around 235. It's 230v phase/live to neutral and 400V between live wires in 3phase. Nowadays 3-phase (120degree between each) is a commodity.

This is a useful explanation.

For the article, i don't want to leave it standing as it is. Redefining "Microprocessors" as "having an MMU" is making communication about these topics very unpleasant, especially when its about Retrocomputing. Same pains as i ranted about in https://news.ycombinator.com/item?id=30278936 .
How old is online streaming? I don't even remember it being that popular 10 years ago. First mover advantage matters now, not in 10 or 15 years.
Resorting to pedantry and refusing to expand your knowledge about the topic at hand by consuming literature contrary to your world view are indisputably bad faith.

There's no such thing as capitalism to me. The things I listed are demonstrably not capitalism

>So either it existed before society or it didn't? Pick one, you can't have both

Pick one of what? Rights exist independent of society. Society and government trampled on them for most of history. Some guys that led a revolution wrote a lot about this and the self evident nature.

As for your last request, I've done that repeatedly and you've repeatedly resorted to attempts to change the topic.

Capitalism and its principles, capitalist societies, and capitalist philosophers have consistently demonstrated the most rapid and prolific advances in ethics and morality in human history.
If you want some reading about boot flow, see e.g.

https://9esec.io/blog/open-source-cache-as-ram-with-intel-bo...

The TLDR is that you need to get DRAM running before you can use it (e.g. by poking at DRAM controller's registers until it knows how to talk to your stick of RAM reliably and at a comfortable speed). Until then, you're stuck with SRAM. On ARM SoCs and Intel Apollo Lake, you use addressable SRAM. On most other x86 systems you use cache as RAM. Cache is just SRAM though, and the only difference between ARM and typical x86's case is that the latter doesn't let you directly address it.

You can find examples of DDR DRAM configuration in u-boot sources, and presumably in coreboot too.

There is a huge, huge difference between the debt you take on in undergrad vs grad programs vs law school vs medical school, etc. You are looking at the numbers for the most expensive programs (that also result in some of the highest paying careers!) to make the case that people have high debt, but those are the minority. They also tend to be the most educated and have the highest future earnings potential. Most people do not advance past an undergraduate degree. The 28k number is far more relevant, and within the article you linked.
I don't like the grandma analogy, some old people are really smart with computers. But in general, if you're in that situation with someone where you're worried that they'll get scammed if you leave them alone for a second, at some point you need to ask whether they should have access to an app store at all.

How many apps per week does your grandma need to install? It would be better if you set her up a phone with the apps she wants, and then disabled all app installation.

Because if someone is in that position, the unfortunate reality is that the official app store isn't safe either. The article gets into this in more detail, but there's enough malware on the official Apple Store to make it dangerous to randomly install apps. There are apps where their whole design is to set you up with big subscriptions in the background that you don't notice, there are malware apps that slip through Apple's review process, there are phishing apps.

Really, you should install the apps your grandma needs, and if she needs more later, then she can ask you about them (or someone else who's an expert). I think people look at the Apple Store as if it's perfectly safe and that opening it up would suddenly let in malware for the first time. But while the Apple Store might have comparatively less malware than Android, that's not the same thing as being perfectly safe, and it doesn't mean you can let a young kid or a naive adult go wild on it and install whatever they want. That's a recipe for disaster.

I've set people up on Linux and had zero support calls or malware problems with them, not because Linux has good security or perfectly curated software sources, and not because there aren't dangerous ways to get malware on a command line, but because they don't open the command line in the first place. Some people are safer and thrive in a computing environment that's set up to do the things they want and that doesn't change after that point -- but I don't think that has much of anything to do with alternative app stores, that's really a question of whether app stores should be allowed at all for those people.

Diplomatically, it would have required more of a confrontation with China, which would could lead to less trade and economic issues. Had it been a lab leak in a much smaller country? I could see both parties taking a much more confrontational role towards that country.

When Fusion is on the front page, I like to take the opportunity to mention the Fusion reactor I have designed.

The device will cycle between a hot dense implosion (similar to NIF) and a cold, rotating cloud, at a very high frequency in a large Penning trap.

I have more information at my website, http://www.DDproFusion.com

If things go well, I should begin building the first prototype in a few months. I just acquired the main magnet, an old permanent magnet MRI machine, that will provide the field for the giant Penning trap.
I don't think "don't be a jerk and you'll be fine" demands an inverse "be a jerk and you won't be fine". It shouldn't matter if other people succeed even "without merit". AFAICT, none of your scenarios of a jerk explain why someone who is not a jerk cannot also get along fine.

If you define your success as relative to others, and if this sort of "undeserved success" bothers you, then I would say you do have a competitive streak. Seeing everything as a zero-sum game is a very competitive outlook.
the 3phase is used for motors - a lot more efficient (and the better power factor) than the single phase ones.
