It's about the multiplayer application case, think Google Write/Sheets/etc. Applications with data that can change by multiple users and you can both see it live and the application (that keeps state in memory/localdb) is also resilient to disconnects.

The reason people descend into this madness is because visible replication code is tricky and the general feeling is that it'll infect parts that shouldn't be infected (or at least not without a general framework).

So at a somewhat trivial level you have:

A: A bare log replication system (where the application needs awareness for most object types multiplying object complexity).

B: A object replication system where the framework handles all object types coherently and the application "only" needs to be aware of how to fetch objects, think a KV store that stores fairly basic objects with some addressing support.

C: Since recent crowd "wisdom" dictates that most KV stores will likely re-implement SQL functionality badly, people go straight to doing the SQL case (maybe they've had a curiosity about SQL databases already that they're scratching)

I've recently built A (basic replication and LWW) and building the application I'm definitively feeling an itch to just start over or adjust to support B (a simple replicated KV store) to separate the concerns more, I can see how I would also feel the SQL itch of C (but having done SQL like systems before it's not as bad for me).

For this first application A will suffice (since the offline needs are relatively trivial) but having a more complicated application in mind I'm strongly considering B for that project (along with designs or third party libs to make it happen).

I think a big gap in the space is that most seem focused on "documents" (esp the CRDT based tools), ie a document being the atomic piece that is synchronized but imo it leaves a big gap in that now all regular application management tools like SQL query tools are useless since essentially you only have a bunch of "blobs" or worse. If you want the regular enterprise SQL backend these tools don't seem to have a focus on synchronizing to those regular backend storage systems.
Regarding the wrong code, I already wrote (and you can confirm in my unrolled analysis):

> every instance of testing `k < 16` is true before we hit UB. Therefore it can be simplified to true without loss of functionality, because after we hit UB, we are allowed to do absolutely anything.

Regarding the correct code, the key insight is that when k is 16, the test `k < 16` is false, so we break out of the loop and avoid reading out of bounds. Always check bounds before indexing the array, not after!

This article is a helpful introduction: https://blog.regehr.org/archives/213

> is the compiler doing a loop unroll and study that parallels your analysis?

Yes, compilers do all sorts of crazy stuff from bounds analyses to loop induction transformations. Personally, I've seen GCC eliminate my second loop variable in an implementation of the TEA cipher because it figured out that the first variable can be derived from the second, and it adjusted the bounds.

> it also seems a bit nuts that these c guys remediated that behavior by allowing an out of bounds index access with their change

You are right, it's insane that they decided to make a special case for one piece of wrong code (SPEC), probably because it's too popular to fail. That's a social/political problem, not a technical one.
It's likely a number of factors as well -- stagnant products, manufacturing issues, competitive pressure -- but it's hard to deny how omnipresent his figure has been, and that the primary audience for EVs doesn't like his efforts to dismantle the federal government and fire everyone.
Tesla promises have not materialized. Beyond big promises there hasnt been much as far as new improvements to speak of. Other good, cheaper options hit the market.
For a complex enough problem (like next word prediction on arbitrary text), I really have my doubts that any such method will result in an "interpretable" solution. More likely you end up with a giant stack of indecipherable if statements, gotos, and random multiplications. And that's assuming no matrices are involved, introduce those and you've just got a non-differentiable, non-parallelizable neural network.
It's a big issue there but it's very localised to that specific area (which is itself in the bottom 25% of areas in the UK). They are like having a whole load of idling lorries sat near your house all at the same time, normally for several days at a time. And all of that is on top of the general level of pollution from being in the centre of London. I'm going from a documentary and a couple of article from a few years ago, which I should try and find.

Hopefully with all the work on both improving the fuel used, and providing grid hookups so they can turn their engines off, that will have made a big difference. Hopefully the effects of the congestion charges have made a big difference too. A lot of the kids featured in the documentary had a really crap life because of it all.
There was a comedian talking about how Musk is now selling trucks after selling eco friendly sedans to anyone who will buy one. People who drive Real Manly Trucks in this country generally don’t jive with the eco friendly crowd so he has to act more like them.

Of course that’s a humorous take, not a serious one but I do wonder how much of that is a part of his thinking.

I do think there is a chance he just runs Tesla into the ground and there definitely is an opportunity for another company to come in and position themselves as quality electric vehicles without the politics.
That's surely a big part of it, but increasing competition in the market for electric vehicles won't help either.

In 25 years in industry, I have never seen estimates proven to be valuable or important, mostly used for dumb purposes, and generally are a waste of time.

At this point I feel Kanban style priorities and limiting work in progress to be only useful approach.

When some product person dumps a huge task in the priorities, break it down into smaller deliverables. No estimates are really needed.
Taking a Responsible Path to AGI
Bloomberg Business TV said this morning it's structural and has been going on much longer than Elons involvement in politics. They spent at least 10 minutes discussing all the various market pressures, china, europe etc etc. I came away thinking this was going to happen regardless. (but imo he's silly for taking an eye off his business interests).
They also have had no new recent models for years except for the Cybertruck, which is reportedly not selling
"I have two guns. One for each of you"
I understand a significant portion of Tesla’s sales are in China and there is fierce competition from homegrown firms like BYD.

That reminded me of the rocket nozzles we designed in my supersonic fluid dynamics course. It's a shame my kids have already outgrown the go-kart stage.
They can't fire him though. Tesla has been a meme stock for years already precisely because of him, and if Elon was out of the picture, it'd drop massively in value.
Maybe, but this highly tech adjacent post about a tech company with a tech ceo that paints Tesla in a bad light is now no longer on the front page, and is flagged.
>I don't mean disrespect towards people running Alpine (hi), Arch, or Gentoo, but you wouldn't be running these distros if you aren't ready to handle their quirks.

You'd think so, but you'd be surprised how many gamers switching from Windows to Linux get recommended Arch and Manjaro
Six of one and half a dozen of the other?

Other companies now have decent EV offerings.

Of course, if you're conspiratorially minded, you could posit that he's taking such polarizing positions especially against the demographic more likely to purchase EVs in order to give an excuse as to why Tesla sales are down.

But I'm willing to accept that it's a bit of both. Rivian and others now have comparable EVs and Elon's been a bit of a dick.
Exactly. As ATP is broken down to adenosine and phosphate to produce energy, creatine re-phosphorolates adenosine.

So it gives you more energy at molecular level. But as you said, you have to actually use that energy.
> a branch in Faroe Islands is a condition for applying for a license to provide telecommunications services according to Faroese law.
Criticizing any company is permitted, right?
This is largely due to the Model Y refresh. March numbers are pretty strong, even in Europe. Not that I support his behavior, especially his position on Ukraine, but facts are facts.
> "In terms of income, I’d try to set up some little online business that gets you about $5k/m"

Ah yes, simple easy life advice that every citizen can follow.

The rest of this .. some is pretty good, especially about not just focusing on computers but on people, but even now I think the "don't go to university" is hugely controversial because a lot of employers do look at qualifications.
> Software development inherently involves more unknowns than fields like construction, making estimation harder.

If by construction you mean only cookie cutter houses and garden sheds, maybe, but construction doesn't end there. As soon as you look to anything interesting, construction has all the unknowns software has and an environment that brings even more unknowns. Computing environments, in contrast, are highly predictable. Software has it easy.

The trouble here is that the original premise is flawed. Construction estimation is almost never accurate. Open today's newspaper and you're almost certainly going to read about yet another construction project that is over time and over budget by millions upon millions of dollars.
Why would “sales rep” be immune to the magical singularity AI that will be 9000 IQ points smarter than all of humanity combined?

Even though our transmission is three-phase, most homes in the US only get single-phase power.
This sounds reasonable. However there was a study showing major economic benefits if was free. These benefits came from more people implementing it, time saved by all those additional users, removal of licensing hassle.
Imo if you aren’t able to AI code at scale, you are probably falling significantly behind the curve.

If I challenged you to build a large piece of quality software using only AI edits, could you do it? If you don’t believe it’s possible (or productive), I would be happy to generate some codebases or products live, in exchange for $$$ ;)
American shakedown: Police won't charge you, but they'll grab your money
I wouldn’t go to university...[instead just learn to code and build a business online making $5k a month.](paraphrased.)

This is bad advice if you're truly seeking to be educated, rather than merely be trained for a job. The problem with self-education is that you'll only ever gravitate toward things that you find interesting or useful. Which is probably just fine if all you care about is making a basic living doing something you enjoy.

But, if you're interesting in learning, there is a lot of value in basically being forced to do difficult things that you don't necessarily enjoy doing in the moment. I might even call this skill a requirement for adulthood, which is full of such situations.

Of course, don't go into serious debt for it, but that's a different question. The value of an education shouldn't be primarily financial in the first place.
The problem isn't ++k per se. The problem is the expression d[++k], which immediately reads d[16] before realizing that `k < 16` is false. Look at your sibling comments for explanations and corrections: https://news.ycombinator.com/item?id=43553392 , https://news.ycombinator.com/item?id=43553519

> And it will still cause trouble close to arrays if size INT_MAX.

Fun fact, `for (int i = 0; i <= INT_MAX; i++) {}` is undefined behavior in C/C++ but a well-defined infinite loop in Java.

Yes, SGCL is my project.

You can't write concurrent code without atomic operations — you need them to ensure memory consistency, and concurrent GCs for Java also rely on them. However, atomic loads and stores are cheap, especially on x86. What’s expensive are atomic counters and CAS operations — and SGCL uses those only occasionally.

Java’s GCs do use state-of-the-art technology, but it's technology specifically optimized for moving collectors. SGCL is optimized for non-moving GC, and some operations can be implemented in ways that are simply not applicable to Java’s approach.

I’ve never tried modeling SGCL's algorithms in TLA+.
There’s no reason to believe that widespread Linux adoption would not irrevocably damage the experience. It would end up looking something like Android. The same thing happened to the internet. It was ruined by mass adoption. You can call this gatekeeping, but nothing positive has come from getting most of the world onto social media.
The board won't do that because Tesla is also overvalued because of Musk to begin with.
The entire article is just the actual delivery numbers without all that much else.

There still remains substantial value destruction ahead of us.
The original implementation is different from what it's turned into. There was a heavy emphasis on listening to workers and understanding why each step of a process was important (or not) and making appropriate improvements. The top-down one-size-fits-all manager hellscape framework approach (scrum etc) is more a product of the Clinton era.

Overparameterized neural networks don't have that problem because there are no local maxima; there are many roads to Rome.
The real evil option is C: 2+"22" = 0, 4+"4" = undefined behavior and probably the value of some other variable.

Don't forget the spectre of economic uncertainty since nobody knows what anything will cost next week. People hold off on big purchases when they're scared.
Curious to see support for the TRT statement - I myself have been on test cyp and anastrazole for the better part of two years with not one side effect. Been in and around steroid users in the strength sport realm for 15. The people with "nasty" side effects are almost always abusers that blast/cruise too often with no AI or PCT e.g dumbasses. Its been a life changing experience for me (going from low 200 ng/dl free T to 800-900 at 32)
Careers are not looking good long-term. Add in the exorbitant cost of uni in the US and dwindling entry level opportunities-- it's hard to see how going through the gauntlet of building a business (including learning valuable, tangible skills and building ones network out) could be much worse than... spending $40k-1m+ to roll the dice in hypercompetitive, saturated job markets.

If you're of modest or lower means, what other choice do you have? Continue taking the advice of a bygone era and hope it works out? Foolish, really.
In the 1920s or '30s Henry Ford stopped or at least slowed with the antisemitic bile that he was spewing in his newspaper The Dearborn Independent, which put Hitler's Mein Kampf to shame and earned him the only favourable American mention in Hitler's book, because it was impacting sales of his cars. The question is whether the same might be the case for Musk, but his wealth seems decoupled from his cars, so it's not going to happen.
You're absolutely right, and, while it's good for life-karma, it's not so good for HN-karma.

No one bullies harder than the nerds around here. Such a hateful bunch of ignorant fools.

Of course, that doesn't apply to everyone here, for sure -- some people are absolutely lovely, like DonHopkins -- but perhaps 90%.

But that's always the problem with majorities, they follow the lead of their leader, and damn their conscience and other points of view, wielding their power like a cudgel. They tend to bully minorities of every kind, especially ideological minorities.

"There is nothing more important than compassion, and only the truth is its equal."
I'm glad you mentioned Genesis because they're the subject of one of my favorite samples. OutKast's famous track "SpottieOttieDopaliscious" contains a sample from Genesis's "Dancing with the Moonlit Knight" and upon learning this, I just thought it was so cool that OutKast listened to Peter-Gabriel-era Genesis when Genesis was very much a progressive rock band rather than the pop powerhouse most know them as today.

multimedia content vs articles. It's easy to see how bad scraping of videos and images pushes bandwidth up more than just scraping articles.

The resource consuming traffic is clearly explained in the linked post:

> This means these types of requests are more likely to get forwarded to the core datacenter, which makes it much more expensive in terms of consumption of our resources.

I.e. difference between cached content at cdn edge vs hits to core services.
I don't buy the idea that Musk is doing this as some sort of branding play. I think he genuinely believes in what he says; his beliefs have just shifted over the past few years, notably after COVID.
I was charging at a supercharger in Las Vegas on my way to California on Monday. While sitting in my vehicle a police car rolled up and asked me to roll down my window. The officer then asked if there was anything suspicious or concerning that I noticed. I said no and he said good we are trying to stay ahead of it. Until that moment I hadn’t really worried about Tesla protests and vandalism.
Show HN: Tambo – React toolkit for AI-powered UIs
Hi HN — I’m Michael. We created tambo-ai after hitting the same wall:

LLMs are great at generating text, but awkward at driving interactive UI with state.

Tambo is a React package that lets AI generate components that:
* Persist state via context + hooks
* Stream responses
* Preserve history
* Suggest next actions
* Component library

You import components directly — no black boxes. Everything’s inspectable and customizable.

This is our first release. We’d love feedback on the dev experience, architecture, or anything that’s unclear.

* Site: [https://tambo.co](https://tambo.co)

Thank you for reminding people of this.
Catering to a population doesn't inherently means that you push for all of its beliefs.

Is any politician that supports Israel to gain support from Jewish voters pushing for Judaism or Jewish (religious) values? Do you think that Judaism, the actual religion, is any more progressive with say, feminism, than Islam?
That movie was such a foundational document for me, and (obviously) for many other nerdy GenX kids.

I found this site years (decades!) ago, and was happy to discover it's still there:

https://monkeybagel.com/culture/movies.html

The blurb there for _Real Genius_:

"The most accurate portrayal of geeks in the wild I've ever seen. The geeks in Real Genius LOOK, ACT and TALK like geeks. And Jordan gave me hope that I'd someday -- just maybe -- kiss a girl on the lips."

I remember a discussion of this film on a long-running private listserv back in the late 90s or early 00s about possible real-world antecedents for some of the characters, including and especially Jordan. A proto-web site existed for this person where she elaborated on her connection to the writers of the film, and more or less confirmed that she was "Jordan", or at least the inspo for it, but of course I can find no trace of this now.

Anyway, between TOP SECRET, REAL GENIUS, WILLOW, TOMBSTONE, HEAT, and TOP GUN, he's about as inconic as an actor can get. For a dose of maybe less blockbustery work, seek out 2002's THE SALTON SEA where Kilmer is joined by Adam Goldberg, Luis Guzman, Anthony LaPaglia, Peter Sarsgaarad, BD Wong, R. Lee Ermey (!) and in a spectacular turn Vincent D'Onofrio.
> [rqlite and dqlite] are focused on increasing SQLite’s durability and availability through consensus and traditional replication. They are designed to scale across a set of stateful nodes that maintain connectivity to one another.

Little nitpick there, consensus anti-scales. You add more nodes and it gets slower. The rest of the section on rqlite and dqlite makes sense though, just not about "scale".
Carmack has been traditionally anti-AMD nad pro-Nvidia (at least regarding GPUs) in the past. I don't know if they could convince him even with all the money in the world unless they fundamentally changed everything first.

I don't have specific stats in front of me, but:

* Q1 tends to be a weak quarter for automotive sales in general

* EV sales in the US have been slowing

* AFAIK, basically every other EV vendor has shown better numbers for 2025Q1 in interim results.

In other words, while not all of the problems can be laid at Elon's feet, it's pretty clear that he is damaging Tesla's brand.
