Is it? Many of us have been doing it from our home ISPs for as long as YouTube has been around. Centralised video hosting might be expensive (but probably not as expensive as you think), but who says it has to be centralised?
fwiw, I don't think they're incompetent! it was a ~4 month project that's due in two weeks now

what doesn't make sense about your last theory, why don't chime in when the multiple specs/documents where defined? why now?

After thinking this through with the answers in here, my current guess is that this is something that just occurred to them, which is totally fine and I shouldn't be frustrated about it, these things happen.
How are you surprise that getting an LLM to spit out a clone of a very common starter project is evidence of it being able to generate non trivial and valuable code - as in not a clone of overabundant codebases - on demand?
Just to let you know, the past tense of teach is taught; so you would say "I wasn't taught this at school". Other than that, your English is great (better than some of my fellow English people lol). Well done.

All complex devices, like CPUs, GPUs, microcontrollers, have tons of undocumented debug features, without exception.

The only difference between devices is whether such debug features remain accessible to users or they are completely disabled after production.

In this specific case, as well explained in TFA, the debug commands do not really provide any additional exploitable capabilities for a malicious programmer, especially because the Bluetooth controller is already hosted on the same CPU as the potentially malicious application, so if that could use the debug commands it could already do anything it wants, like sending arbitrary Bluetooth packets. The Bluetoth driver also can already do anything it wants on the shared CPU, so if it had bugs or backdoors that can be triggered by received Bluetooth packets the existence of these debug commands does not change anything.

Unlike this case where there is nothing to criticize in the reply of ExpressIf or on what they have done, an example of atrocious handling of the undocumented debug features has been provided by Apple, whose devices had for several years, until the end of 2023, a backdoor created by non-disabled debug registers, which allowed a total bypassing of the memory protection, enabling (in conjunction with some bugs in Apple system libraries) complete remote control of an iPhone, and which has been exploited for the remote and undetectable spying of some iPhone owners (discussed on HN at the time of the public revealing of the CVEs).
One fairly common reason to not document something is not wanting to commit to supporting it or to keeping it around in future releases. Document it and customers will come to depend on it and then you might be stuck with it.
things ARE reversed for special traders in specisl markets, like when metals went crazy a few years ago, and a major trader got caught out in a deal with a huge amount of nickle, and that and some other trades, were let off the hook.
Now it's one more example of markets bieng rigged, not just through barriers to entry , but also that the trading "floor" is now somewhere secret and operating under flexible rules.

There are massive costs of not doing those things – and, as far as I can tell, those costs are greater. Coal is expensive and irradiates the atmosphere. Oil drilling causes spills, fracking causes earthquakes, and oil dependency has been a major driver of war for the past century.

Every single person selling second hand board games is in this position. No one is setting up a single listing for each game. And this is hardly unique to board games.

Obviously, allow an option to indicate that a listing consists of different items with different prices, and to specify a range. "40 second hand games, $30-80", it's not complicated.
This looks really cool, but I am just wondering how is it different from sending the site to a chatbot and asking it for the color palette?
Yes, I think you make a good point about the deadline. It's an internal deadline, but I do feel like this team was formed to build this particular feature, so missing it would be a big fail.

Based on that, I feel like the blame won't be on the TL, which is what worries me, but that's probably unfunded/unfair.

I worked with a guy who insisted on using Neovim to work on a large Java monolith project. He was surprisingly unproductive. Took days to deliver features (code) that folks using IDE (Intellij IDEA) could crank out in a matter of hours.

The danger of not using an IDE is that you will fall behind in productivity and get fired because you are not performing at a level expected from your seniority.
It’s based on some of the same sources describing historical economies of other countries/regions. There are a variety of sources accessible online that go into more detail, including the ones cited in the excerpt I’ve included below.

> India experienced deindustrialisation and cessation of various craft industries under British rule,[12] which along with fast economic and population growth in the Western world, resulted in India's share of the world economy declining from 24.4% in 1700 to 4.2% in 1950,[13] and its share of global industrial output declining from 25% in 1750 to 2% in 1900.[12]

I wish someone made social media where everyone gets one post every day. Almost no person on this planet has more than one bit of news to share daily with their extended social network — probably not even the countries' leaders. When accounts share every 10 minutes, it's often spam or some inorganic agenda.

Oversharing in natural social networks is penalized heavily, and for good reason - with too much noise and little signal, people get overwhelmed, fear missing out, and cannot agree on anything. Communication becomes a detriment and a chore to the social group. The social group expects everyone to think before they speak, not just blabber endlessly, which is healthy.

Also, replacing the "Like" button/signal with a "Thanks" signal would be good because it'd be better to build a social network based on what people find helpful rather than on what people approve of. I think this was originally Jack Dorsey's idea, not my own.
Skool Alternative
In my opinion the best alternative to Skool at the moment is Odd Circles.

Because ultimately you will only make money with your skool community when you actually bring members to it. There is no discovery benefit on skool because it does not promote communities across other communities.

But to pay $99 to manage your community per month is too much. That is why I moved my community to Odd Circles because here I do not pay anything until I want to use paid features.
Can you elaborate on that? Why would it be significant and what could it mean?
Thanks, I think this is good advice. Planning to do something around those lines.

Or maybe the explanation is that everybody behaved "responsibly" but they never got the changes they wanted, and chances for anything different looked more and more bleak. Why do you treat this like a single event? It is not. Lots of prior experiences fed into this.

For example, as bad as this is for us (I'm German, but I lived many years in the US once), for Europe I think it is good what is happening. Now we are forced to move and mature. Crisis are not always bad. The personalities involved this time make it especially hard to look at the whole thing calmly. I admit I have a harder time seeing what the US may get out of this except for the shakeup as a general chance. However, too much is concentrated on the personalities, and, like you did, on blaming everybody. How about Democrats look what they did wrong? I mean, other than reverting to "we didn't think the voters would be so stupid", in which case I have little hope for them to get anything positive out of this.
I use an Apple Watch, and while I don’t necessarily care about its accuracy in terms of steps walked or other specific details, I do value the insights it gives me into my daily activity. Even if it’s not entirely accurate, I get a reasonable estimation of how much I’ve moved, stood, and worked out. My watch motives me to me more active.
Etrian Odyssey released in 2007 and was a fun throwback to this sort of experience. The concept for this game is that the Nintendo DS's touch screen can be used to draw a map and keep notes while dungeon crawling. It's funny to think that it's about as old now as the style of games it was imitating then.

The 3DS also had a note-keeping system built into the main menu and usable in any game, but I don't think many people bothered.
I switched to Zen a while ago and while for the 'main browser window' it's fantastic I often open multiple smaller windows (in a tiling VM) and hated having to manage collapsing the sidebar.

I've done this around the same time and agree. Now google is used as a service (Firebase for example). The only thing I haven't been able to effectively shake off is their Calendar. I know lots of other options are available the issue is connectivity with others.

Show HN: Advanced Code Search with Tree-sitter AST and Qdrant Vector DB
For the past couple of months, I’ve been building a tool that enables natural language search over large codebases using Tree-Sitter for syntax parsing and Qdrant for vector-based retrieval.
https://app.repogram.com

### How It Works

- Tree-Sitter is used to parse syntax trees and extract high-quality vector embeddings of code. - These embeddings are stored in Qdrant, enabling fast similarity search across your entire repo. - A combination of re-ranking processes refine search results, producing highly relevant answers to code-related questions.

The results have been incredibly accurate, thanks to the quality and structured nature of the embeddings. I've been working through the TypeORM issue backlog with some excellent results.

Repogram doesn’t just help you search code, it enables a shared, evolving knowledge base:

- Questions are converted into public, protected, or private threads that remain searchable by repo members. - Over time, this builds up tribal knowledge that acts as an interactive alternative to traditional documentation. - Threads can be optionally summarized into searchable pages, making it easier to navigate discussions.

### Getting Started

- Enter a GitHub repo URL or name. - Sync the repo to generate embeddings. - Query your codebase using natural language.

### Currently supported languages:

- TypeScript - Javascript - Rust - Python - Go - Java - PHP - Swift - Ruby

...with additional support for Markdown. I’ll be adding support for more languages over the coming weeks.

To get started, log in with GitHub to start exploring. I’ve already synced a few large open-source libraries like TypeORM, Fastify, and BullMQ, so feel free to experiment—or sync your own projects with a fine-grained PAT via the UI.

It's still very much a work in progress but the UI is fully functional. If you hit any bugs, let me know and I’ll patch them as quickly as possible. Would love to hear your thoughts! Feedback, ideas, and feature suggestions are all welcome.
Thanks for the comment! You’re absolutely right, taking a screenshot and asking an LLM for insights is easier than ever. My goal with Colorize isn’t to replace those tools but to provide something more precise and structured for designers and developers who want quick, extracted color data without manual work.

colorize.design doesn’t rely on AI guesses, it directly extracts color data from multiple sources (Favicon & homepage screenshot, HTML, CSS, and JS files)

That said, if you see ways to improve it, I’d love to hear your thoughts!

I've in no way surveyed the whole wifi mcu market. But wasn't the "beginnings" of Espressif in the western world that it was a cheap wifi mcu that was at the time very popular in cheap Chinese wifi enabled products.

The DIY market (at least in the west) came later. I still remember reading the hackaday article about them being discovered back in the day - https://hackaday.com/2014/08/26/new-chip-alert-the-esp8266-w... and back then all the documentation was in Chinese.

I remember a ton of cheap Chinese wifi enabled stuff would come with an esp for a good while, until even cheaper wifi chips hit the market.
Perhaps this is telling us that the financial losses and inefficiencies incurred from these supposedly error-prone processes are small enough (relative speaking at least most of the time) that there’s no real consequences to the stakeholders (politicians or bureaucrats in this instance) or the survival of the organisation (this org isn’t for-profit after all). So from the stakeholders’ POV it just doesn’t justify putting the investment upfront into proper software systems. Without greater accountability and real stake in the org from the politicians and bureaucrats, headlines like this will continue to appear in the decades to come.
>putting the result of the election into the hands of a small minority of voters

Are you referring to the final 538 electors who actually make the final vote? Most of them are bound to vote based on who their state voted for. Aside from some rare exceptions (like that WA elector that voted for Chief Spotted Eagle in 2016 as some sort of weird protest).

Or are you trying to claim that only swing voters in swing states are responsible for the outcome of the election? Because that's a fallacy I've seen a lot of people make recently that I'm just going to start calling "the tiebreaker fallacy". If you have a panel of 101 voters where 50 people vote one way, 50 vote the other way, and one person is the tiebreaker, you can not make the claim that only the tiebreaker's vote counts. All 101 voters were part of the process. At any time, any of the other 100 voters could have changed their votes and the outcome would have changed.

Now we have a different discussion, about "internal" or "external"
legibility.

We used to live in a world of high trust in vendors. Those days are
gone. Vendor malware is a massive and growing problem and supply-chain
legibility is a hot topic.

FWIW I'm arguing the fully open position. Unless you've desperate
trade secrets, there is no "internal". And if you've a 16 bit register
that's 65536 entries, most of them sparsely documented as "no op".
And if a researcher finds it does something,... it's suspicious by
default.

This "no user serviceable parts" is an old schism in technology.
Today we have almost blanket rights to repair and openness is the new
security model.

> Irish one is seen as something special because it happened in the West, and because overpopulation there built up for a considerable time being allowed by potatoes farming

There was no overpopulation problem in Ireland! It was _less_ dense than England, while having similar climate and agricultural capacity. The reason for the famine was that the food that was abundantly produced in Ireland was transferred to England to support their cities (which did have an overpopulation problem). There was more than enough food produced in Ireland to feed everyone in Ireland. That is not what overpopulation looks like.

It's also easy to say no major famines happened in Spain because of her colonies, except that by the time of the famine she had very few remaining. Spanish people had the same capacity to emigrate to the Americas as the Irish did. Your argument was that Irish people were too Catholic to control their population but you haven't addressed the fact that that wasn't a problem in any of the other Catholic countries. The same should be true of Italy, who didn't even have a former empire to call on.
I doubt a bit of UV on a vacuum does anything to a mite. They're kinda like spiders with a hard shell after all. One study [1] found you need one hour of hard UV-C exposure to kill most mites. That would probably also degrade the textiles and foam of your mattress, and probably does not even reach most mites/eggs in between threads and foam pores.

I struggled with peeling hard-boiled eggs literally all my life until I finally realized what the problem had been right along. If eggs are stored below a certain temperature, which I estimate at 38F though I have only used consumer-grade thermometers, they will not peel. And this applies both before and after cooking. Since I learned this, and adjusted my cold storage accordingly, I have had no problems, except occasionally when a batch sold through a particular retailer apparently got too cold somewhere along the supply chain. The word "freeze" is not appropriate but the egg albumen does undergo some kind of irreversible change below the threshold temperature -- and suppliers are evidently aware of this, as it is very unusual for eggs to be damaged in transit by excessive cold. But if you keep your fridge at or below 38F, you're asking for trouble.
The problem is that they can't be customised to whatever the UI/UX team dreamed on their PowerPoint,Photoshop,Sketch,Figma,..... drawings, expecting platform capabilities like on native GUIs.

Thus even if supported, they don't do those cool UI/UX workflows sold to clients, and that is how we still end with a div/css/javascript soup, or back to Flash like approaches, now that WebGL/WebGPU/WebAssembly has brought that tooling back into the Web.

Excel is an incredible swiss army knife that can be used to do a lot, but it has a mean-time-to-catastrophe. You can keep spreadsheet risk (==cost) under control for a long time, which can make it seem like the risk is negligible, but it's a ticking time bomb.
