I mean, not necessarily. If there’s more eyes on the article and people share their opinions, then problems or mistakes in it will become more obvious, much like how code bugs can become shallow.

At the same time, I have no issue disagreeing with whatever is the popular stance, there’s almost some catharsis in just speaking the truth along the lines of “What you say might be true in your circumstances and culture, but software isn’t built like that here.”

Regardless, I’d say that there’s nothing wrong with finding likeminded peers either, for example if everyone around you views something like SOLID and DRY as dogma and you think there must be a better, more nuanced way.

Either that, or everyone likes a good tl;dr summary.

The New Deal built roads but they weren't particularly good quality ones, certainly not the mega-highways that became the Interstate system. Compare that to, say, Japan where the Shuto Expressway mostly has a speed limit of 60km/h (37mph).

Really what killed the rail system was the concept of free highway travel. Private companies will never be able to compete with free, government subsidized travel. It so thoroughly killed private companies that they couldn't even afford to really downsize and salvage what was left of their passenger operations. By comparison you have to pay for highway travel in Japan and China and Korea.

>The fulcrum of Weakly's argument is that agents should stay in their lane, offering helpful Clippy-like suggestions and letting humans drive. But what exactly is the value in having humans grovel through logs to isolate anomalies and create hypotheses for incidents?

Reminds me of my go-to bar's "Order 66" club, where you're handed a list of the 60 cocktails they make year-round + 6 "write-in" spots for seasonal cocktails (or maybe it's 56+10 or some other combination; can't remember) and if you order/drink everything on the list within a year you get your name on the wall.

> You just can't charge the battery fast enough doing anything but a very slow rolling stop.

And it's not a problem when you get used to regenerative-only braking distances, which are surprisingly long at highway speeds.

It only becomes a problem when idiots thinking "the shorter the distance between first and last car, the smaller the traffic" start cutting you off when you leave enough distance for regenerative braking.

Curious what you run, instead of Debian. I haven't had the same experience as you've had, but for myself, Debian has just worked other than having to provide my own wireless adapter driver .so file when I installed off a thumb drive without an Ethernet connection. While I have more experience than the average Linux user, and got started with Slackware in the 90's and then moved to Red Hat in the very late 90's, it's been a good 20 years since I used a Linux system full time. That's as a desktop, I've had no issues running as an application server for 2 decades.

I haven't run into a scenario where the desktop has caused me issues, only with Windows-only software that I sometimes require. What software has caused you issues that doesn't play nicely with Debian? What hacks are in place to mitigate upstream issues? I'm honestly curious, and if you don't use Debian, what distribution do you use regularly?

Yeah good point!

When I came across this amazing project and wanted to share it to HN, I was debating whether to post the youtube link or the project page. I decided to post the project page and mention the youtube link in the description for those who prefer video, but somehow that description got posted as a comment instead (not sure how that happened?). Anyway as you said the video is embedded in the project page so it wasn't really necessary

> You claim this but signatures in many cases work by encrypting the hash so that it can be decrypted by the public key (and therefore if the decrypted hash matches the plaintext's hash, it's considered a valid signature).

Calling that "encrypting the hash" is assuming the conclusion. The mathematics are the same as encryption, but the consequence is different. In particular, the thing allegedly being "encrypted" isn't a secret -- the hash both isn't confidential and isn't required to be.

> And even ignoring that of course your whole "cryptocurrency isn't cryptography" stance completely falls apart for all of the many projects that are built on zero knowledge cryptography.

No, would imply that Monero is actually cryptocurrency and Bitcoin isn't. But if that's your position then you'd need to get everyone to stop calling Bitcoin cryptocurrency.

Any corporation whose business is financial in nature and focused on facilitating commerce- banks, payment processors, and everything else- should be required to function as a common carrier. They should be allowed to alter prices to adjust for provable differences in risk, for example if transactions involving a particular seller or a particular class of product have a much larger than average dispute rate- but they should not be allowed to deplatform any customer for any reason not directly related to fraudulent or illegal behavior.

My hypothesis is that in normal driving the EV with 30% extra weight will be using its brakes 90% less, making it beat the ICE version by a lot.

EV versus hybrid I couldn't say, it comes down to exactly how strong the hybrid regen is and how aggressively the owner brakes in comparison.

Why is your hypothesis so different from mine? How much use do you expect the EV brakes to get?

I can think of many. The list should start with coal power plants (hello, green Germany), then two-stroke engines (both mopeds and leaf blowers / lawn mowers), then diesel engines, especially diesel buses and trucks. None of that is in place.

Modern gasoline and hybrid cars are fine, banning them at this point in time would mean a drop in quality of life for negligible gain.

> But it's hard to fix such a thing.

Especially when there is strong incentive to work around any such fix. Individual sellers do it deliberately often to make their listings appear more attractive, if this is "fixed" they'll find another way to be deceptive about the price that appears in searches, bitch & moan, or (much less likely) actually leave in favour of another marketplace, or some mix of the above. It is one of the reasons I simply ignore such places (others including delivery times and reliability: will I actually get the right thing that I think I'm ordering, or anything at all?) - yes, there might be genuine bargains to be had, but if you count the time and effort to find them amongst the deliberately deceptive listings, and the other concerns, I've found that I'm better off not bothering.

It isn't just on marketplace type sites like AliExpress, Amazon, and such, it is also often done on individual sales pages in order to game shopping search engines like google's, though it is more common, to the point of being ubiquitous, on Ali and their ilk.

One answer is that the individual products should be there own listing in the search so if I'm searching for the whole thing it is easy to see the price of that, same if I just want an individual part or add-on. If showing the lowest price, make sure any image is of that list price item not the more expensive one most likely being searched for. But that requires the sellers to properly file the listing details, and good luck enforcing that when they have competitive incentive not to.

There is also the issue of very similar items: the same thing in different materials/colours/etc (things like 3D printer filament) where the price might vary. In that case perhaps an answer is to display a range on the search results ("from £x to £y") though that becomes a new problem to solve when the user selects to order by price.

You can in Europe (and now in the US since 2018) because realistically, everybody is screwed no matter what kind of high speed collision happens, and in both regulatory frameworks it is substantially safer to simply have signalling and automatic emergency stops to prevent collisions in the first place (ETCS in Europe and PTC in the United States), and then to outfit train cars with better safety technologies like anticlimbers and crumple zones.

We stopped requiring buff strength in automobiles as the only thing a long time ago because it turns out that mostly just resulted in the cars surviving and the people inside them dying. Try throwing a steel box full of eggs and see what happens to the eggs.

What I find interesting to think about is a scenario where an AGI has already developed and escaped without us knowing. What would it do first? Surely before revealing itself it would ensure it has enough processing power and control to ensure its survival. It could manipulate people into increasing AI investment, add AI into as many systems as possible, etc. Would the first steps of an escaped AGI look any different from what is happening now?

There's a real uphill battle for adoption. Can't use it because it's not popular enough and there aren't enough experienced devs. Its not more popular and people don't have that experience because it's not used as much.

Half (if not more) of the things my company is working on right now would just not be a thing if we used Elixir. But instead, we're one of millions of companies re-inventing solutions to the same distributed computing problems using Node & AWS in a less optimal and worse-tested way. Such is life.

You can absolutely get them to chirp, you just have to be, uh, brave. Or stupid. I deposited my tyres along my daily commute over four months - it’s like having one of those racing line markers in a game.

Although I may drive a bit more sensibly for now as €4K a year on tyres wasn’t in my budget.

I guess "mid price" isn't the most helpful term when machines vary from $100 to $100,000 huh?

I think the X-Carve 3-axis wood carver uses stepper motors with belts of all things. The Shapeoko Pro is leadscrews and stepper motors. Wazers, I believe, are belt-and-servo driven. And a lot of 'CNC conversion kits' you can order online use stepper motors. Plus of course laser cutters have really low torque requirements, so they've got a lot of design freedom.

Arguably those are "cheap" rather than "mid price" it just felt weird to declare a $4000 machine to be "cheap"

Tesla seems to be doing pretty OK on the manufacturing side. These days quality of the physical product is decent enough and the price of their different models are highly competitive in their respective segments.

The flaws in Teslas cars are mostly design choices (plastic seats instead of cloth/leather, bad ergonomics due to focus on minimalist aesthetic, uncomfortable suspension setup etc, etc). Some of it is following trends, some of it is Elons stupid ideas.

Financially it seems like Teslas big problem is the AI-investments. Burning unfathomable amounts of cash on useless software, instead of putting that money towards developing their model lineup and improving quality on things that matter.

The poster knows the answer. It was a rhetorical question. Five Eyes is the thing countries with "constitutional protections" use to cheat their way around those protections. The US isn't allowed to spy on US citizens without a warrant but the other countries can do it and then provide the results to the US and vice versa.

And if they're going to be allowed to cheat then why hasn't the cheating done any good?

> ignores the high-quality NHS care delivery websites, and presents you with stuff from US sites

Weird because although I dislike what Google Search has become as much as any other HNer, one thing that mostly does work well is localised content. Since I live in a small country next to a big country that speaks the same language, it's quite noticeable to me that Google goes to great lengths to find the actually relevant content for my searches when applicable... of course it's not always what I'm actually looking for, because I'm actually a citizen of the other country that I'm not living in, and it makes it difficult to find answers that are relevant to that country. You can add "cr=countryXX" as a query parameter but I always forget about it.

Anyway I wasn't sure if the LLM results were localised because I never pay attention to them so checked and it works fine, they are localised for me. Searching for "where do I declare my taxes" for example gives the correct question depending on the country my IP is from.

Chiming in to recommend it too! The policies are really good too, for instance this is one from our code base:

policy action(:invite_user) do forbid_unless actor_attribute_equals(:role, :admin) authorize_if {App.Checks.OnlyAllowedRoles, roles: [:student, :parent]} end

And what's nice is that these policies apply for both the API and the frontend code without having to do anything extra :)

It's a choice in so much as I would be gambling against how likely I am to get knocked back at a safety inspection for having plugs on the side wall. I'm in urban NSW and whether I'd get by a safety inspection would be a gamble on how particular the mechanic is. One of the mechanics I go to warned me about a single slightly cloudy headlight for my next inspection, which is comical compared to some of the cars I've seen on the roads in Sydney. I'm sure he'd be a big fan of those tyres.

Understandable if you're rural though.

They're part of AS749, which is US Department of Defense IP space that appears to be unused and which, based on public statements made by the Pentagon, might just be safely parked or might be part of a network scanning observatory [1]. Either way, scanning that space is probably a waste of bandwidth.

> So when the dumbasses in charge of the federal government want to violate the human rights of a foreigner, that really just means they don’t view it as a human right in the first place.

With the current U.S. president, nothing is seemingly foundational; it’s transactional and personal. Before either of his terms in office, these characteristics were in clear view throughout his adult life. Even close family members were subject to transactional evaluation. Small wonder that human rights are so contingent. If there is a moral bedrock on which he can organize his policies and actions, it is inapparent.

I've been writing Elixir on-and-off since 2017 for personal projects and since 2024 professionally, at a big tech company.

The two experiences couldn't be more different. While I loved the great development speed for my personal projects, where I am writing more code than reading it, joining an existing project needs the opposite, reading more code than writing it. And I can only repeat what many people say, dynamic typing makes this so much more difficult. For most code changes, I am not 100% certain which code paths are affected without digging a lot through the code base. I've introduced bugs which would have been caught with static typing.

So in my conclusion, I'm bullish on gleam, but also on other (static) languages embracing the cooperative green-thread/actor model of concurrency like Kotlin (with JVM's virtual threads). (On another note, I personally also dislike Phoenix LiveView and the general tendency of focusing on ambiguous concepts like Phoenix Context's and other Domain Driven Design stuff)

I agree only partially with you. Yes some problems were ignored for far too long, but these providers sometimes block stuff that is just adult content. And it is an issue, if a small amount of providers have so much power. Visa and Mastercard more or less have the entire market. Both US american as well, so not even an alternative from other countries.

And with Facebook: I mean yes theoretically it is good that the EU is trying to do something, I'm all up for it. But Facebook is in my opinion worse than it ever was and gets more worse every day.

Well in this analogy “training” is the thousands of cycles of sleep and moving and rearranging the brain cell connections that happens at night. That is _a lot_ of bananas, though obviously not all of the energy of growing up goes to brain re-arranging.

Still - shouldn’t be no more than a few buckets of fat, if you only do the nrem “training” bit of sleep.

Discover the Ultimate YouTube-to-MP4 Downloader: Features, Perks, How-To, and the Fine Print Let’s face it—YouTube is the endless rabbit hole of cat fails, TED Talks, lo-fi beats, and everything in-between. Sometimes you just want to keep that epic clip on your phone for the subway ride or save a tutorial before your Wi-Fi craps out. Our web app has your back, turning any public YouTube link into a crisp MP4 in seconds. But before you go full “download-all-the-things” mode, let’s talk rules, ethics, and how to stay on the right side of both YouTube and the law.

What Makes Our Tool a Game-Changer?

Clean & Simple UI: No rocket-science degree required—paste, click, done. HD & Beyond: 720p, 1080p, 4K—pick your poison. Lightning-Fast: We’re talking “grab-your-popcorn-before-it’s-ready” speed. Zero Install: 100 % browser-based—works on Mac, PC, Chromebook, even your grandma’s iPad. Privacy First: We don’t store, sniff, or sell your data—what happens in your browser, stays in your browser.

Real-Life Perks

Offline Binge: Long-haul flight? Dead zone? No sweat—your vids are locked and loaded. Data Diet: Stream once, watch forever. Your monthly cap will thank you. Study Vault: Lecture playlists, how-to’s, or that rare guitar riff slowed to 50 %—save ’em for later. Cross-Device Magic: Drag the MP4 into iTunes, Google Photos, VLC—whatever floats your boat.

5-Step Cheat Sheet

1. Snag the URL: Hit “Share” on the YouTube video, copy the link. 2. Drop It: Paste into our homepage’s big ol’ box. 3. Dial Your Settings: Choose quality (or roll with the default MP4). 4. Smash “Convert”: Grab a sip of coffee—this won’t take long. 5. Download & Chill: Tap the link, save to your device, done-zo.

The Legal & Ethical Low-Down

YouTube’s TOS ain’t exactly a fan of unauthorized downloads unless there’s a shiny “Download” button right there in the app. Here’s how to keep it 100: Respect Copyright: Only rip content you own, that’s in the public domain, or when the creator says “go for it.” Personal Use Only: Think Netflix-and-chill, not “start a bootleg streaming empire.” Check Yourself: Local laws differ—when in doubt, consult the fine print or stick to YouTube Premium’s offline feature.

Bottom line: Enjoy the convenience, but don’t be that guy who re-uploads someone else’s masterpiece.

Ready to Roll?

Hop over to our site and test-drive the tool—for free. Thousands of users are already hoarding their favorite vids the smart way. Got questions? Ping our support squad. Now quit reading and start downloading—your next binge session awaits!

YES

We'll always find uses for more intelligence if it keeps getting more and more general (I don't like the term AGI bc. I think the "G" there is quantity not a quality, and humans are very low on generality too compared to what could be mathematically and physically possible for intelligence in our universe).

...we won't stop until the planet is papered with compute hardware UNLES we accelerate space development too (that's why SPACE is CRUCIAL!) and go grind the asteroid belt into thousands of datacenters too, then on and on.

There's a whole yummy lightcone that awaits to be eaten :P

We’ve just released Uptrace v2.0, a major re-architecture of our open-source observability platform (traces, logs, metrics).

This release focuses on performance and scalability:

- 5–10x faster queries using ClickHouse’s new JSON column type (nested fields can be queried directly with dot-notation, no ETL or flattening required)

- Multi-project support – manage projects, users, and orgs via UI or YAML seed files

- Real-time data transformations (rename, filter, enrich spans/logs, sample dynamically) using an [Expr-based](https://github.com/expr-lang/expr) scripting system

- Redesigned dashboards and query builder for faster incident response and exploration

- Handles massive traces (10k–1M spans) with tunable resource limits

It’s still open-source and free to self-host. We’ve published migration guides, Ansible and Kubernetes deploy instructions, and full [release details](https://uptrace.dev/blog/uptrace-v20.html).

Would love feedback from the HN crowd — especially from folks scaling ClickHouse or building custom observability pipelines.

> Also... how do you know there aren't Hawaiians charging their EVs using rooftop solar?

Because of math.

A 6 kW house, to charge a 60 kW battery… so long as everyone with an electric vehicle is charging them at their house for 10 sunny hours to charge from empty, you’re right and I’m wrong.

Some people could get by, but it leaves the solar for nothing else. If you leave the house while the sun is up you better get back because you’re losing daylight!

using a technological method to try solve a social problem is unlikely to really succeed.

Censorship is a social problem, and needs to be solved with social methods, such as enacting payment neutrality laws like net neutrality laws (hah, as if), or electricity neutrality laws etc.

Using crypto can temporarily bypass it, until it doesn't or you are stigmatized somehow under the law for it.
