I watched this years ago and really enjoyed it. One of the main lessons I took from it is basically, have almost 0 text on your slides. You should not be reading your slides, the audience should not have to read your slides. The slides should supplement what you are speaking about, not vice versa.

Any time I see a wall of text on a presentation, I know I can probably tune out and not miss much.

It being more expensive in Britain doesn't mean it doesn't work the same way (just come out with a lower price) elsewhere in the world.

From your electricinsights article:

> Most markets work in this way: Saudi Arabia’s oil is cheap to produce but gets a very similar price to higher-cost oil from the North Sea. The underlying economic principle is so widespread that it’s known as the Law of One Price.

The title made me think of piezoelectricity which isn't new and has many applications.

However, it seems that it's a similar but different phenomenon called "flexoelectricity" which was discovered around 1964. It was also predicted before discovery.

Bing Copilot helped me find an article which looks like a good overview of flexoelectricity, although mostly over my head.

https://arxiv.org/pdf/1307.0132

"First-principles theory and calculation of flexoelectricity" Jiawang Hong and David Vanderbilt

First paragraph:

Flexoelectricity (FxE) describes the linear coupling between electric polarization and a strain gradient, and is always symmetry-allowed because a strain gradient automatically breaks the inversion symmetry. This is unlike the case of piezoelectricity (coupling of polarization to strain), which arises only in noncentrosymmetric materials.

It goes on to say that interest has been revived after ~50 years because of finding ways to make the effect ~3 orders of magnitude stronger, and because nanoscale structures also magnify the effect.

The earliest reference is to a Soviet physics journal which I assume is not online:

S. M. Kogan, Sov. Phys. Solid State 5, 2069 (1964)

> Because having their own state isnt their goal, the destruction of zionism is

Oh of course, these are not people- they don't want their own good, they want to destroy others. Is this what you mean?

> israel was content to let the palestinians chill until oct 7th while hamas spent the previous two decades bombarding tel aviv

You obviously don't know that Israel bombarded Gaza killing 1800 people in 2008/9, 430 people between 2010 and 2104, 2270 people in 2015, plus 800 more between 2016 to 2023? This 4 times the victims of October 7- and we don't count the blockade and the wrecked economy.

> We dont have to be racist to point out that hamas fucking sucks and has done nothing but make life worse for everyone in gaza

Yes of course, blame the victims. No, Israel has imprisoned 2 million people inside Gaza for 20 years and periodically bombed them, and this is an unimaginable crime, orders of magnitude worse than Hamas ever did. Frankly, October 7 was horrible but nothing in comparison, plus it was obviously needed to bring the necessary attention to the situation. Fucking sucks, but hey, that's something Israel brought upon itself thanks to its criminal behaviour and the complicity of the West.

> Shareware isn't even open source, generally, and it certainly isn't gratis--you have to pay for it, or at least should, and there are often restrictions or time limits if you don't. Again, the "free" in "free software" refers to freedom, not free beer.

Yes. The comment you are replying to already said this: ‘Free/libre software is distinguished from "gratis" software’.

Your earlier comment wasn’t wrong for saying that ‘free software’ refers to freedom; that part was correct. But it was wrong for agreeing with a comment which claimed that ‘free software’ means ‘copyleft’. Copyleft is free software, but free software isn’t always copyleft.

Saying that ‘free software means copyleft’ is like saying that ‘bird means goose’. Goose is a kind of bird, but not every bird is a goose; just like copyleft licences are free, but not every free licence is copyleft. The responses (which you called incorrect) were trying to explain this important difference.

I don't have an issue quoting LLMs in and of itself, but the context and how you present it both matter.

"ChatGPT says X" seems roughly equivalent to "some random blog I found claims X". There's a difference between sharing something as a starting point for investigation and passing off unverified information (from any source) as your own well researched/substantiated work which you're willing to stake your professional reputation on standing by.

Of course, quoting an LLM is also pretty different from merely collaborating with an LLM on writing content that's substantially your own words or ideas, which no one should care about one way or another, at least in most contexts.

This can't actually be one of the largest stocks of second-hand books. That's just 50 of me, and I only have a couple walls full. He's got 25 rooms, which very much sounds like 50 of me. I'm poor, I'm not special.

I wish I could get rid of them all; when I want to read one again I just pirate a scan. I've literally thought about tightly wrapping them in plastic and burying them in a concrete vault. After the original texts of all "legacy" writing have been deemed too provocative, somebody could discover them and dig them up, show their friends how they've been changed since everything went digital, and shortly afterwards get arrested as a terrorist pornographer.

> But if the code already exists and is working, is it really that costly to just not break it?

It depends on the feature, but in many cases the answer is in fact 'yes.' There's a reason why Alpha support (defunct for decades) still goes on but Itanium support (defunct for years) has thoroughly been ripped out of systems.

Could also introduce a mechanism for homeowners to correct the official city record, with documentation. Under a LVT the incentives would be in place for this, because undocumented improvements generally improve the structure value of the house, which homeowners are not taxed on, yet if the structure value is subtracted from the recent sale price it would reduce the land value, which homeowners are taxed on. (This is not the case with a straight property tax, where homeowners have every incentive to lie about improvements to avoid a re-asssessment.) And it's in the city's interest to have accurate records about the state of each home.
by kelnos | 2025-09-01 21:59:49+00:00
To be clear, this was not a vibe coding exercise, despite the title. The author supervised and reviewed the code changes at every step, caught mistakes and sub-optimal solutions, and worked with the LLM to fix and improve those problems.

This is not someone who just said "build me X", left it to run for a while, and then accepted whatever it wrote without reading it.

(I'm not criticizing the article's author here. It was an excellent, thoughtful read, and I think an article that was actually about something vibe-coded would be boring and not really teach me anything useful.)

If you’re not familiar with the experience of browsing the internet and then suddenly having deeply-held parts of your identity deemed undeserving of respect, it’s the kind of thing that the mind naturally develops habits to avoid, in much the same way that you might start to walk differently through a city after getting mugged. It is indeed tiring for everyone, but the solution is not to blame people for doing what they feel like they need to do to protect themselves.
by em3rgent0rdr | 2025-09-01 22:00:34+00:00
Yes and no. A problem with 8-bit and 16-bit for desktop and servers is the limited memory address space, so the compiler has to insert extra instructions to deal with things like updating the segment registers. And likewise if you need to do higher-bit math then the compiler again has to insert extra instructions. Those extra instructions clog up the pipeline, but aren't needed if your largest program's working memory set and the largest precision math you generally need fits within the ISA's bit size. Unless you are doing scientific computing or other large-memory set tasks like Blender (which dropped 32-bit support), then 32-bit really is good-enough.

I couldn't tell if your comment was a joke, but it is worth mentioning the 8-bit microcontrollers like TinyAVR still fill a niche where every joule and cent counts.

Probably too much assumed context. I’ll expand.

A good deal of ADHD masking/coping mechanisms show up as trying to control certain parts of the environment. We need to do this thing that way and keep this thing at that location and never ever do X but instead Y.

It can look like someone who needs those things for other reasons, like mild OCD or even autism. But it’s really about preventing everything from going to shit in the worst ways that we cannot deal well with.

So while your room may look like a bomb went off and your fridge is half empty, there are certain things you are super precious about. Because a little work now saves a lot of grief later, and for those little islands of sanity you find the motivation to perform them.

For me this is mostly at work. And the things I need to be a certain way help everyone during an emergency. High cortisol levels make every brain more like an ADHD brain.

> The meme is still alive that windows accumulates garbage and becomes slower with time, so you need to reinstall it periodically.

I've not needed to worry about this since Windows XP. Which was what? 25 years ago almost.

> Reinstallation is also how you fix regressions, because ms is busy with cloud services.

I've never had hardware regressions with Windows. I've had plenty of weird and annoying bugs return with Linux.

e.g. My Dell 6410 has an issue where the wifi card would die after suspend with kernel 6.1. However it would get fixed by a patch, and then get unfixed the next patch.

> As I remember, on linux I have an ample choice of kernel versions, but I didn't encounter regressions. For windows intel provides only the latest drivers.

"Swings and Roundabout".

Again. It is a pretty niche problem. I've had plenty of weird hardware regressions with the Kernel. Recently there was a AMD HDMI audio bug, IIRC it was kernel related.

I am a software engineer with over 6 years of experience building web applications.

Since my first website at 10 on GeoCities, I've gone on to work on Minecraft custom servers, MMORPGs, web application used by millions, and led volunteer teams to deliver IT services powering a homeless shelter network every Christmas.

I enjoy being "the glue" to IT projects, working across disciplines to ensure they get delivered on time, meet budget and satisfy users. I specialise in modernising legacy applications using modern technologies and frameworks, and have created greenfield applications from scratch.

I prefer full-stack development on the web but can also specialise into backend / frontend and other disciplines as needed.

Without open standards, we would need to pick a browser and provide for it.

If we needed to support another browser we'd need to provide a new solution built to its specification.

Open standards have allowed the possibility of multiple browser vendors, without making the life of browser consumers (i.e. developers and organisations providing apps and sites) a living hell.

Without this, we'd be providing apps and sites for a proprietary system (e.g. Macromedia Flash back in ancient history).

Furthermore, when Flash had cornered a market, it had absolutely no competition at all. A complete monopoly on that segment of the market.

It took Steve Jobs and Apple to destroy it, but that's a different story.

--

The reasoning for only three engines, isn't the fault of open standards.

There are many elements of our economic system that prevent competition. Open standards is not one of them.

I'm not sure which comment you're responding to, because I'm not talking about shared_ptr, but about how atomic operations in general are implemented on x86.

I don't believe that shared_ptr uses seq-cst because I can just look at the source code, and I know that inc ref is relaxed and dec ref is acq-rel, as they should be.

However, none of this makes a difference on x86, where RMW atomic operations all lower to the same instructions (like LOCK ADD). Loads also do not care about memory order, and stores sometimes do, and that was what my comment was about.

Yes. I run my mail server on a Raspberry Pi 4 on OpenBSD. Aside from having to flash an SD card (and having the install program install the sets to… itself) everythhing works exactly as you expect on any other OpenBSD install. You can’t really stray far outside the list of supported hardware unless you plan to roll things yourself, however. Eg, I’ve discovered that Waveshare carrier boards for the CM4 are hit or miss. NetBSD has much more comprehensive support for Raspberry Pis and the various accoutrements.

Pretty excited about Pi 5 support!

And it can't even do that without an Internet connection. As someone who experiences annoyingly frequent outages, it never ceases to boggle my mind that I have a $200 computer, with an 8" monitor and everything, that can't even understand "set a timer for 10 minutes" on its own.

This type of "innovation" feels like a skit from the Silicon Valley TV show. That and Apple's patented "squircle".

Give me the vintage MacOS and Vista designs from the article over whatever the new fad of UI they keep trying to shove down our throats. It was flat UI before, now glass again but this time with raytraced refractions, so we waste compute power to get the glass buttons to look more realistic if you pixel peep.

I could swear we're living in a parody when I hear this being said with a straight face.

Not only that, but all the compute spent, and hardware bought, will be worthless in 5 years.

Just the training. Training off of the internet! Filled with extremists, made up nuttery, biased bs, dogma, a large portion of the internet is stupids talking to stupids.

Just look at all the gibberish scientific papers!

If you want a hallucination prone dataset, just train on the Internet.

Over the next few years, we'll see training on encyclopedias and other data sources from pre-Internet. And we'll see it done on increasingly cheaper hardware.

This tiny branch of computer sciences is decades old, and hasn't even taken off yet. There's plenty of chance for new players.

It's pretty disappointing that this video alludes to, but does not cover performance curves for condensing dehumidifiers.

Even when they don't freeze over, condensing dehumidifiers rapidly lose efficiency at lower temperature and/or relative humidity.

I didn't test as comprehensively but from my observations based on the effect on relative humidity, I found dessicant dehumidifiers to be more effective when RH was ~60% and temperature was ~50-60 degrees.

And in my case I wasn't double dipping by increasing ambient temperature, I was using a dehumidifier which vents the moist air out without condensing it because I needed something that would work below freezing

> Public transport is great in theory only

I never felt the need to have a car in most of Europe, so didn’t even bother to get a driving license. Urban population is 75% on average, so reaching rural or uninhabited areas is almost an edge case (at least for me). So it is not theoretical, it works great, even if it is not reaching the perfection of Japan. Looking at two of my favorite cities, Berlin and Moscow, I find that they are spending reasonably on expanding networks (and the most recent highway project in Berlin — extension of A100 — was very expensive and stupid, looking at the traffic jams there).

That’s an interesting modern perspective.

I would say though that you’re both correct. Satya came in 2014 and during the last 11 years I would say that the majority of that is as the GP described.

I’m not sure when what you are describing became the outside perspective, but I suspect somewhere around 2019-2022, when Google lost a very large amount of its shine as the former Oracle Execs started to take over fully.
