Above certain speeds, pulses based systems have timing issues. How many pulses can you cram in before they start to merge due to signal noise? Assuming serial communication transmitting 9 pulses is more than the 4 needed to represent 9 in binary (assuming 0 is represented by no pulse, not a single pulse with no signal at all indicating an error condition). If you allow variable length transmissions pure pulses become more efficient overall, but synchronising multiple signals potentially becomes more difficult.

So you fix the signal merging issue found in multi-level signals, but introduce other similar difficulties. Both sets of issues get more problematic as signalling speed increases.

I've never understood how the difference between the editions being just a matter of having different bits set means "marketing is bullshit". How's changing the bits post-install different from, say, having Workstation vs. Server come on different CDs with those bits flipped? It's all bits in the end.
> This publicly goes back to Clapper telling congress that the NSA doesn't "collect" data on Americans. The lie was excused on the grounds that "collection" isn't them saving the data, but rather querying it later.

More conspiracy theory nonsense. The lie was that they don't collect any data on Americans, when they did collect phone metadata. The reason he made that mistake was that the previous question was about making dossiers of Americans, which they do not do, not having the content of any Americans' communications.
The Firefox build system feels to me like kind 1. The Synapse Matrix server also feels pretty close (although I don't understand why it doesn't use Pydantic or something like Pydantic).
Once again, I wonder the focus on foreign actors, as I would expect the problems to be very much domestic, regardless of a country. But maybe they don't have a mandate for the latter; I don't know.
That sounds very familiar to me. I'm now retired but in my last job I put together a simple C++ framework to do something similar. I used this in a small part of a financial trading application. Like you, I was convinced it would pay off to apply much more widely, but I found it difficult to "sell" the idea. As you say, the real payoff comes in complex situations, which simple examples don't really convey.
However lots of people seem to be playing around with reactive programming now, so perhaps it's an idea whose time is coming.

That is true, but SciresM has exhaustively reverse engineered the latest Switch kernels from end to end and stated confidently that there's nothing there to exploit. It's a tiny microkernel so auditing the entire thing is actually feasible, nothing like the enormous potential attack surface of the Playstations FreeBSD kernel.

Obviously not a sufficient argument for it to be “fucking fair”. If the consequences of using such technology “overharm” populations underrepresented in the data, it is obviously not fair.

Even election polls correct bias due to underrepresented populations among the responders.
Windows Mobile in 2007 was based on Windows CE, a completely different and much more limited kernel compared to desktop Windows. Symbian and BlackBerry had the same limitations: these were operating systems designed for embedded devices, not desktop-level computing. They were memory efficient but their growth path was nonexistent.

The original iPhone OS used the underpinnings of Mac OS X: the Mach kernel, CoreGraphics, the Cocoa Foundation APIs… At the iPhone launch, Apple even called the phone operating system “OS X” to highlight that it’s the same.

I have a Brother HL-L2350W that I paid $120 for, and is a basically perfect black and white printer for my needs. Plugged it in, set it up on Wi-Fi (LAN only). It goes into deep sleep after a few minutes of zero use, but even after weeks hitting print on any system in the house (no third-party drivers needed, at least on Mac) wakes it and the first page is out of the machine before I can walk over there.

I'm sure that, like any other company, they have better and worse products -- but I did very little research on this, bought to price point, and have been very happy. Certainly not the HP experience.

The thing is, information on how to do it in a safe and healthy way is available, sometimes even from your national food agency.

The problem is, I think, that people do not follow the guidelines of the food agencies anyway. If you follow the guidelines but on a vegan diet, making sure to supplement b12, you won't have to do any planning. A healthy dietary pattern looks the same if you don't eat meat. People most often just have to make sure they get enough calories.

That is a very good point.

However, the other side of the coin is that in many Python codebases I've seen, people keep using multiple antagonistic ideas/paradigms in the same code, way past the point where it should have become clear that these ideas are actually incompatible and no amount of heroic hackery will solve the issues.
Honestly, I think you're just pulling some of these user preferences out of nowhere. Or at least you're greatly underestimating what is acceptable. Its not like people don't use sunglasses and ski-goggles. Eye contact is nice but proven to not be necessary in many many cases.

That’s wild. Self replicating bloatware. How could this even be legislated against? I can’t figure out how to legally qualify something as “bloatware” vs something the user would want to automatically download/update.
Sequoia PGP is pretty nice, but the issue is not so much the signature/encryption library, or even the interface, but the key management (after all, as far as the end users are concerned, PGP signing and encryption are simple commands). If this was easy, there would have been many solutions by now. Integration with a hardware-based KMS service will go a long way in improving the security. I don’t think the algorithm or file format is the main issue here.
Absolutely. And I am sorry I reacted this way.
Vim or Neovim? Here's Why You Should Use the Latter
Yeah I was there for those (edit: similar I mean, different context) conversations with H1 - the goal is better human contextual awareness on the factory floor - the amount of things that need to be 'newly explained' on the floor should be 0. This negates this whole AR/VR 'support staff / training' spatial context. It's like cycling with training wheels after you've been riding for 20 years... it makes no sense.

(we this found out with GM doing a pilot)

[Edit] to keep it going, external cameras are how you verify parts are picked correctly and put in the right place - you don't need FPV for that to be verified either.

[Edit 2] Until a flight simulator uses VR and AR headsets as primary training, this stuff just doesn’t make sense. CAE has definitely explored with this but it’s not what they reach for
JSON is trash and should never be used in any human-interfacing context, so I'm super skeptical that there's any utility in trying to fix it; that would just delay its demise, to the detriment of humankind.

But if you did want to fix JSON, the yes, trailing commas and comments are the absolute minimum bar, but single quote is actually probably the the third absolute must-fix.

The reason is just that so much JavaScript tooling is now configured to autoformat code (including the JSON bits) to swap " to ', thanks in large part to Prettier (which also should almost never be used, sigh, but that's a topic for another HN bikeshed...)

hexadecimal identifiers, yeah, nah
> Maybe this was primarily done based on the users being comfortable with a GUI driven system?

FWIW I started prototyping a plaintext accounting 'app' that combines a popular plaintext accounting system (beancount) with the most used web frontend for it (fava) - it's called beancolage and makes use of eclipse theia (vscode-like experience): https://github.com/seltzered/beancolage

My observation is the plaintext accounting ecosystem is wonderful but a bit diffuse to so many specific usecases held by a more technical userbase. My aim for prototyping beancolage was to ask how things could look if there was a more common 'download and try' experience accessible to more people for basic workflows. Also have a talk on the motivations here: https://youtu.be/mxgoFqmSCFc
China bans Micron’s products from key infrastructure over security risk
Legitimate question, but the answer is simple: No.

The cost of CO2 capture largely depends on the concentration of CO2. Transport is relatively cheap. If you capture from the atmosphere, that's the most expensive thing you could possibly do.
That's also why people try all kinds of things to increase CO2 concentration. Like Oxyfuel technology, which basically means you're burning without nitrogen, so what you end up with has a higher CO2 content.

It's also why CCS is hard in industries where by design CO2 concentration in the exhaust is low (Aluminium is one of them), and why most of the existing CCS projects are at facilities that by design have high CO2 concentrations (mainly gas upgraders).
I wonder if comparing embeddings could work here? It might be more resilient to cosmetic changes.

The real question: how can pip still not allow me to verify a downloaded package with a public key of my choice (PGP key or others, the format is irrelevant)?

In most cases, I don't even want to know who the author is, but just be warned if the signing key changed since last time (possibly because pypi has been compromised, which is the elephant in the python ecosystem room).

This minor feature has been blocked for years on ideological basis (and matched to questionable decisions like hiding on purpose the signatures from the pypi UI), on the grounds that keys are not discoverable and not attached to a strong identity (which happens to be an argument close to what this article say).

Just add that possibility, make it opt in, and allow the ecosystem to figure how out solve the key management/trust/identity problem.

The "self-made person" and "pulled by bootstraps" narrative is very American. People love to frame their success as the outcome of their own effort rather than from a source of privilege. If you read accounts from entrepreneurs, almost all of them will tell such a story, mostly glossing over attending elite schools, having connections, or receiving large amounts of funding. Even Cal Newport normalizes this in "so good they can't ignore you" by saying that "small breaks" such as connections to a VC are relatively common. I guess I must live in a different planet.

Some years back I could usually find a cheap HP printer on sale for around $30. For the amount of printing I did, the starter ink would usually dry up before it was empty, and new ink cartridges would run over $40. It was more cost effective for me to throw away the printer and buy a new one instead of replacing the ink.
The meal plan example may be able to go even forward, because I think ledger-cli can also track your calories and macro-nutrients, apart from the ingredients themselves. I meant to do a calorie counting system in ledger-cli for some time, but did not quite get to it.

>ignoring the high unemployment

High youth unemployment, and no, it's fundementally a symptom of why PRC is improving in scitech and industry. State over capacity is generating like 4-5M STEM a year, 20% means they're finding jobs for 4M STEM and like 6M (out of 8M) undergrads, that's a stupendous amount of skilled talent entering the workforce relative to anyone else. West and folks who wank over PRC unemployment should be shaking that PRC ONLY has 20% youth unemployement. Is there enough job supply to match talent oversupply? No, but there's still a fucking crazy amount of jobs to compete globally, relative to when PRC was producing 2M stem per year with 10% youth unemployment. The net increase in high end opportunities is doubling per year relative to 00-10s. Hence PRC moving up these innovation indexes and supply chain value. Not to mention youth unemployment is only high because high household savings lets a lot of urban youth lounge around for options, which aren't always good, eventually they'll give up and settle, which is why broader unemployment is like 5%. Or quoting unrelated stats like home foreclosures that doesn't shit like science output, you realize US S&E output increased during GFC and other economic downturns when people were losing their houses right.
My sentiment exactly: childcare needn't be that expensive or highly skilled, and therefore teachers needn't be (and generally are not) highly skilled either.

They don't command high salaries because pretty much any responsible adult with minimal skills can do a passable job of what we consider to be passable teaching.

It's not that GPT4 is a great teacher or great teaching aid (although it's not bad). It's that a classroom teacher with 30 students in a room, rattling off that week's geography unit, might as well not be there, except as a run-of-the-mill babysitter.
Not and be compatible with the OpenPGP spec. You can define a safe subset of OpenPGP with some additional restrictions (like no weak keys) but that won't be PGP any more, it'll be a new protocol.
It's worth pointing out that experts love Feynman's lectures. They're elegant and subtle, and are great for refreshing why and how you think about physics.

Pedagogically, Feynman's lectures were a failure. They aren't well structured to teach novices physics. Outstanding students might learn from them, but those same students would also learn from a ratty textbook.

I'm a physicist with a PhD, so I love Feynman's lectures. I also care about pedagogy and my students' development, so my copy of the lectures sits next to my copy of Jackson and Sakurai, on a high shelf that first-years can't reach!

> I went back to the store and bought him an iPhone SE. That was years ago now and haven’t heard a single complaint since.

I would assert that the iPhone SE is the best smartphone bang for the buck, especially for users in your family with a tendency to shoot themselves in the foot and need your assistance.

The $399 iPhone SE from 2016 got six years of OS updates and just got another security update last month. That's about $57 per supported year.
> I can start with every module in prototype form and industrialize each module as its design firms up.

That is definitely the theory. And this flexibility is indeed very precious for some types of work.

However... does it actually happen as you describe? I can count on half of the fingers of one hand the number of Python codebases that I've seen that actually feel like they've properly been reworked into something of industrial quality. All the other codebases I've seen are of the "I guess it works, maybe?" persuasion, quite possibly because there is always something higher priority than quality.
> I think android phones aren’t for the tech illiterate.

As an Android user, I think I'm on-board with this sentiment. Anecdotally, most of the people I know with Android phones are in IT; specifically software engineers.

I once had to transfer files that were downloaded on my phone to a work laptop that couldn't access the external internet and no access to external storage. I installed Termux on my Android phone, dropped to the linux terminal, installed http-server and spun up a server on the local network. I was then able to download the files I needed off of my phone.

Quirky scenarios like the one I mentioned where I can "MacGyver" my Android phone is why I really like the platform. And then there's F-Droid so I don't have to deal with those pesky apps from the Google Play store.

Is the efficiency gained by capturing it from a stronger concentration enough to offset the costs of building pipelines?

Why not burn wood in a room near the destination site and get extremely concentrated CO2 right there and capture that instead?

Are pipelines somehow even more economical than that?

It’s up to the app developer. It’s trivial to provide “Save File” and pick exactly where you want it to go.

The part that really sucks is when it’s “Save Image” and that is treated differently when sometimes you just want the file.
I think you're still misreading my comment (and dragonwriter's and Knuth's): we all know or can look up what temperature is in randomized algorithms. However, what temperature 0.7 means is a mystery to me. I know that at temperature 0 the result is deterministic, and at higher temperature the randomness increases (possibly they are the Boltzmann factors associated to some energy function, but I don't know, and even if it is, I have no idea how it is scaled, i.e. what is the value of the Boltzmann constant). I know that the API accepts values from 0 to 2. I don't know more. Do you?
It makes sense for disk persistence to be io but redis is primarily in memory. So I don't think async applies to that aspect of it. In theory that makes it so all operations on the database from the user perspective are serial.

Not sure about this that's why I'm asking here for a definitive concrete answer about this.
> B) there’s a lot of tricky stuff with indices on PG and you generally need a DB admin from day 1

Sorry this is absolute nonsense. Any software engineer worth their salary should be comfortable working with RDBMS index concepts and interrogating their relational model to determine best practice and direction for table indexing.
