I was listening to a Titus Winters podcast, and I’m not sure he exactly put it like this, but I took it away as:

There are two problems with automated testing. 1) tests take too long to run 2) difficult to root cause breakages.

Most devs solve this with making unit tests ever more granular with heavy use of mocks/fakes. This “solves” both problems in a narrow sense: the tests run faster and are obvious to root cause breakages.

But you didn’t actually solve the problem. Since the entire point of writing tests in the first place was to answer the question: “does my system work”? Granular and mocked unit tests don’t help much.

However, going back to the original question, we can actually reframe the problems as: 1) a work scheduling problem and 2) a signal processing problem.

Those are pretty well understood problems with good solutions. It’s just that this is a somewhat novel way of thinking of tests, so it hasn’t really been integrated into the open source tool chain.

You could imagine integration tests automatically be correlated to a micro service release. Some CI automation constantly running expensive tests over a range of commits and automatically bisecting on failure. Etc.

Put another way, automated tests don’t go far enough. We need yet another higher layer of abstraction. Computers are better at deciding what tests to run and when, and are also better at interpreting the results.
Correct. No mptcp on windows and android as of 2024
Just because most adtech is the equivalent of Internet billboards on the side of the highway doesn't mean these systems aren't in place. You don't even need a very complex system when the entire device platform is designed to spy on you.

Take a look at this for example: https://www.theverge.com/23293687/amazon-irobot-acquisition-...

Even simple ad systems are a huge privacy threat. Add to that audio, location, and even AI screen reading surveillance, and you're screwed.
> the median Android device spec was actually going down.

What is so great about the top end phone that I should get one? They all have cameras (plural) with more pixels than I can see. They all have a fair amount of storage.... Sure the top end models have more of everything, but is there anything that I as a user would notice?

I was one of the first to have an Android back when the G1 came out - the hardware was lacking, but any phone from 4 years later was good enough (except none had a slide out keyboard that was so much nicer than touch screens)
Obviously this is a completely buffoonish question made by someone who has extremely limited knowledge but...what on earth do we mean by "homogeneous at high scales"? Doesn't the existence of stars, galaxies, and galactic clusters with enormous voids in between clearly show the universe is not homogeneous in any meaningful sense? I know the phrase "high scale" is in there but, I mean, if you zoom out far enough, it seems like you could claim anything is homogeneous at a sufficiently high scale, although I don't know what that would mean on a universal level anyway, since you cannot zoom out of the universe.
We can create enough compute and SRAM memory for a few hundred million dollars. If we apply science there are virtually no limits within in a few years.

See my other post in this discussion.
Honestly, do not think so, but its close enough.
I feel like you're mixing the domain which you are programming in, versus "programming" as a concept, while I'm focusing purely on programming.

I do understand that different domains require different skills, that much is evident in itself. But then we're moving on from just discussing programming to also discussing programming domains, which detracts a bit from the core discussion.

Seconding this. Skyfield is a great tool maintained by a great guy, Brandon Rhodes. I've built many a production tool for spacecraft with it.
Accessibility is a good point. Though I can’t think of any disabilities where I couldn’t type but could drag and drop components, which is a much more precise as well as sustained physical motion.

I suspect there are better ways for coding in those scenarios. Like perhaps the kind of word entry that Stephen Hawkin used.

Or if you were to go totally touch UI (I’ve known one individual with motor
disabilities use an old touch screen CRT with a stylus in their mouth) then you’d want those blocks a little taller but with something more akin to Miro’s infinite zoom. Rather than a text UI with mouse input.

That said, every project has to start somewhere. So this might be that proof of concept needed to fully flesh out accessibility tweaks.
The equations are really simple for a homogeneous universe

https://en.wikipedia.org/wiki/Friedmann_equations

It's only recently that people have been able to handle the more complex case of an inhomogeneous universe. Scientists are often like the drunk who is looking for his keys under the lightpost.
because the timings were not possible for humans. problems were solved in under 2 minutes. I've experimented with LLM for few days too. yielded the same results.

How did we get from SRE culture to (paraphrasing) "I personally think Google makes worse products than IBM, Oracle, Apple, Netflix, Broadcom, et al."
Interesting thread. Here's a story: long ago when I found myself running a bootstrapped startup, I worried that I didn't know what I was doing, business-wise. I had worked for, and knew, a guy who had become something of a business guru and VC and wealthy and successful. Everyone here has heard of him. I called him up and set out my situation and asked him how he recommended I should approach things. He listened and said something like "Oh dude, I'm out there on the ledge with you, I don't really know what to do most of the time." So I never worried about it again.
I think you are referencing La aventura del Amazonas by Dominican monk Gaspar de Carvajal.

He was one of the survivors of the first European expedition through the Amazon and provides the only account we have of something resembling the pre-European Amazon. He talks about large cities with tall structures, roadworks, and very elaborate societies - nothing compared to our common notion of the Amazonian people.

His account was largely dismissed because it was never replicated, but those who believe it to be accurate theorize that this first Expedition unintentionally caused a population collapse by introducing European diseases. You can imagine that by the time other expeditions were organized, it was a completely different place and the jungle would have easily overgrown any abandoned cities.

Good starting point: https://en.wikipedia.org/wiki/Gaspar_de_Carvajal#The_Relació...

You said Arab states should just be demanded to give Palestinians citizenship.

You think Israel needs to exist as a Jewish majority state because other countries did not accept Jewish refugees (e.g. the US) even though those same countries could and would do so now (at least as much as the Arab countries would for Palestinians).

So just think about that hypocrisy. Either being hated and rejected as refugees justifies a state of a group's own, or it doesn't.
Sure, I can get behind that. That's why we just automate these trivial things away.
It looks like a PR would be appreciated xD

Not everything is a VC funded thing. This is clearly a research project at a university - notice the ff.cuni.cz links in the images.
Amazing idea!! It starts making me think differently. Thank you so much for sharing this. Could you tell me more about storing and sharing the "gist/pastes" for later use? For example the link validity, or share only with a certain group of people?

Eh I don't think that is what happened here. If other companies want to know how Apple did things 5 years ago, they can just hire some ex-Apple employees. I think someone could build a competitive system with current technology for something in the ballpark of $95 million lol.
Yeah, the high frequency input capabilities of hands/fingers on keyboard are pretty remarkable and hard to beat, especially in conjunction with navigation tools like vim and especially when you start considering things like stenography applied in a programming context (intellisense/copilot etc can in some ways be be considered a form of that already).

I suspect natural language speech is too slow, but i do sometimes wonder if the only other part of our body capable of such high throughput (and the requisite fine motor control) is our mouth/tongue… I’ve always wondered what a programming language optimized for spoken input would look/sound like.

Edit: mentioned this in another comment, but I think graph based visual programming languages would actually be pretty well suited to speech entry, especially with shorthands for common operations like “create node” := “kurr” or “connect” := “kuh”.
> but when easily preventable problems happen

easily preventable is doing a lot of work here. This is assuming the types are already written and never need to be maintained. How often does the type checker catch a problem with the code vs the type definitions themselves?
It was a lot easier for me to deal with dark mode rather than white screens back before I had my cataract surgery. To a lesser degree, it still is.
Wow, so glad to see the author's idea and this as well.

After playing with this stuff it hit me why these systems are simultaneously so attractive and also not amazing.

Human brains are still way better at the very cool linking thing. We make those connections better than the bots.

Which is why I dream of, and tried to start work on one that was basically "cards."

I'd love to see one with "the card" as the main atom/unit -- but that had a zillion different visual "arrangement" methods. Give me alphabetical, give me semantic, give me random etc etc.
I'll do that ASAP
That's not how copyright works. The copyright owners want to maximize earnings, and the licensees/distributors also want to maximize earnings -- they are typically for-profit businesses, and as such they have a fiduciary duty to maximize earnings. If they think that DRM will help them, they'll want DRM.

Of course for music DRM has proven to be pointless. People want to stream music, not buy music, and preserving media across so many media obsolenscence events has been such a pain that streaming is the only manageable solution for most people -- consumers don't want to make and manage copies anymore.

The same should apply to movies and such, but maybe not -- it's not clear yet.
>How would the content creators or news sites earn then?

“Creators” seem to do just fine with the patronage model.

Not my problem. I am not required to prop up your failed business model.
Maybe? I've used some light themes for coding that have pretty good color coding.

I really think it just comes down to what you use first and what you've learned to be productive in. And for coding, the legacy of monochrome monitors and terminal interfaces is just really, really strong.
I've been on a quest to find out what went wrong with modernity. Looking through the history, I found out the Renaissance was not what I thought it was. The history of the Silk Roads were not what I thought it was. And I haven't revisited the history of the industrial revolution, but it looks so far, that is where the obsession with maximizing productivity, gains, and work all come from. It is very likely when I look at it again, it is not what I thought it was either.

The significance of perennial food forests is that it's a practice that comes from a very different world view than our normative one that came from the industrial revolution. Yet there's a tendency to evaluate something like a perennial food forest from the world view of maximizing productivity. Maybe we're talking past each other a bit -- I have not put a lot of thought into the difference in how civilizations arose in the old world vs the new world. The patterns of design for something like the perennial food forests in the Americas have shown up in the Old World as well.

I haven't found Occam's Razor very effective in explanatory powers. Treating the minimum path as the floor is one thing; treating it as the most probable theory (and then making decisions based upon it) is something I have concluded for myself as folly. Just my personal opinion; I'm aware I don't hold a popular opinion.
They missed perhaps the most important reason for resistance to introduction of Extreme Programming (and any other labeled bundle of practices): resistance to cargo culting.

These kinds of bundle-of-practices-given-a-label feel very consultant-y to most developers, which triggers a ton of natural suspicion. Rather than looking at each practice on its own and showing how it fits into existing workflows, the bundle-of-practices is justified with somewhat handwavy explanations (and they must be handwavy, because we haven't talked about specifics yet), then each practice comes pre-justified because it's part of the bundle.

If you want to effect change in a good engineering org composed of rightly-cautious engineers, you can't give them marketing copy for a bundle-of-practices and expect buy in. Instead, you should use the bundle as a starting point for investigating the specific practices that you'd like to see implemented, and then explain and show why you believe those specific practices will work.

"We should do XP" breaks down into "we should do TDD" and "we should do pair programming", but it also breaks down much further than that. Start with "when I write a failing test before implementing a feature I find that I move much faster". Discuss specifics, not consultant-fueled buzzwords.

VoxelSpace: Terrain rendering algorithm in less than 20 lines of code (2020)
To expand on this a bit, the hypothesis stated elsewhere is that the register renamer stores "physical register + 11-bit signed immediate".

It should be possible to construct scenarios where a logical register is mapped to "physical register + immediate" where the immediate depends on the path taken through the program so far. The easiest example would be an if-statement that optionally adds 1023 to a register, and then an add of 1 after the if-statement. The add of 1 overflows the immediate stored in the register renamer if and only if the if-condition was true.

As you said, that requires taking different control flow paths through the program, which is something to be avoided by constant-time algorithms anyway.

One potential twist: This shows that it may be important that the interface between the constant-time algorithm and the rest of the program goes entirely through memory and not through registers. If the interface does go through registers, it's possible that variable register-renamer-immediates leak from the outside world into the constant-time algorithm. (This admittedly feels like a bit of a stretch, but who knows.)
Data centres in space: they're a brilliant idea, but a herculean challenge
I wish I knew the precise steps. I've certainly wanted to rage quit FB in the past but I'd be socially isolating myself since I have friends that post there. Also, FB Messenger is my most used communication tool though I could use that without using FB.

I'd love to know what A-B testing, if any, FB has done here and if their methodologies for ascertaining results are actually correct. For example, it's obvious that the success of TikTok has them pushing "loops", one of their TikTok clone efforts. I'd personally like to completely block "loops" from my life except maybe if a friend recommends one, and I'd have a better opinion of FB if they let me. I can guess that might not translate to better metrics on 1 billion people but I can also imagine not annoying people would lead to more engagement.

I quit Instagram because it was ~1 relevant post (a friend) to 5+ irrelevant posts (non-friends) and their redesign to try to push me to follow non-friends by only showing non-seen friend posts and then filling my feed with non-friend spam. So, I quit. Is that a loss for them? No idea. I only know I'd have stayed if they let me opt out of the push to be TikTok.
Japan and America: Two Paths, One Bridge
I use it for some security analysis.
I almost needed to do that for running the uninterruptible power supply needed for a 4090 rig. I decided to squeak by with a 1200 watt UPS, but theoretically I should have a much higher wattage UPS, which would have required a special outlet. I balked and decided to live with 2 minutes power at max draw in an interruption (which is rare where I live anyway).

I mean... You wouldn't just plug that into the wall and allow all the inconsistencies of household power to have their way with your rig, right?

>What is your most scarce resource if not time?

I would argue attention is more valuable than time. After all, if all your time is spent paying attention to the wrong things, how valuable can time be? I would urge the author to look at what is commanding his attention and that might give some insight into his malaise.
Back in the 1990s when researchers went to write about millionaires they discovered most people who look rich are in debt such that they have less to live on day to day than poor people - they have nicer houses and toys but for their day to day budget they are in trouble. When they found people who had a high net worth they were living in poor neighborhoods and otherwise looked poor - but their bank account was big. Then they wrote "The millionaire next door".

After looking at life I've concluded both are wrong ways to live. you should save 10% for retirement (that is a good number for discussion but I'm open to other numbers). Spend the rest on toys - but don't go into debt. You can't take it with you, and do not know for sure that you will be healthy enough to do whatever activity you are saving up for in retirement. (at 50 my body is already such that I don't think any amount of training could get me ready to climb Mt Everest - good thing that was never my dream because it is too late. I could have done that at 30 if I wanted and there are plenty of less extreme things I can still do)
The science keeps getting stronger and stronger on this.

Excited for the day when I do not have to justify to my friends & family why I do not want a drink.

Many point to the rise in depression and social isolation as a counterweight to the discussion on alcohol's negative effects, but my take is that once the social stigma of refusing a drink is severely lessened and social spaces adapt, that argument will also dissolve.
I think this video is good Ressource on the topic.
