What’s your definition of “unproven” which doesn’t cover what Tesla has achieved, but does cover what Waymo has achieved? Hint: one of those has driven at least two if not three orders of magnitude more miles unaided by humans.

Just to be clear, because a lot of people who don’t follow this closely may not appreciate it, the 3-D spatial awareness component of Tesla’s stack has been solved problem for a couple of years now. The long tail problem is path planning and decision-making. LIDAR doesn’t make that any easier, even in theory.

I use a VPN and firefox and I get some extra captchas but not enough to be annoying. And you don't have to do anything more than tap the checkbox.

Meanwhile a bunch of "security" products other websites use just flat out block you if you're on a VPN. Other sites like youtube or reddit are in between where they block you unless you are logged in.

Cloudflare is the least obtrusive of the options.

no, it isn’t unreasonable at all.

i’ve noticed a large uptick over the past couple years of some people insisting it’s unreasonable to consider context and known past behaviors when we try to discuss things.

again, no, it’s not unreasonable. actually it would be incredibly silly, more unreasonable to ignore their past behaviors when discussing this.

Individual savings will always be gobbled up by people higher up, who have the power to do it. There's nothing that's being left on the table by regular people. They'll just end up making their lives more miserable while solving exactly nothing, just adding more anxiety about the whole thing.

How about we start taxing wars? Those surely are very carbon expensive. Nobody says anything about that, but everybody wants me to take shorter and shorter showers, like that solves anything.

> It's a mystery why D isn't far more popular than it is.

There's no mystery. It's a jack of all trades, master of none. E.g., the virality of the GC makes it a non-starter for its primary audience (C/C++ developers). The need to compile and the extra verbosity makes it a bad substitute for scripting like Python. Etc.

Basically, name any large niche you'd expect it to fill and you'll probably find there's a tool already better suited for that niche.

Yes, horrible starts as a scapegoated minority that can’t defend itself, who are treated performatively badly to shake out whowever won’t go along with the excess. These become the next trailers. This keeps expanding to include anyone who has any opinion different from the leader(s).

The continually incrementally enslaved majority is told that each thing they give up is just a temporary sacrifice until they have lost all their freedoms. Even then, their hardships are blamed on scapegoats, to maintain their “leader’s” grip on their minds and loyalty.

Anyone raising alarms is a traiter.

Watching the Republican Party metamorphose into group think, hero worship, the last couple decades has been deeply troubling.

Seeing the inability of any effective opposition or remedy, has been equally troubling.

The scaling issue the author identifies is exactly what we've built Strong Compute to solve. Dynamically scalable super computing.

"In this environment the problem with a single big unit is that significant updates to it are likely to be quite expensive and you probably simply won't have that money all in one lump at once."

This is true if you approach it as a long term lease, or a fixed purchase, which is often a requirement given even if using on demand or spot there's still a lot of setup work to do. Our focus to crush this issue. Zero code change from a small VM to a large cluster.

Who knows. I have lots of siblings and my spouse does as well, so that’s nine vacuums accounted for. Add in both sets of parents and I’d have one left over to gift to someone who also needs one.

I’m not sure how to take your comment other than uncharitably so I’ll just concede that you obviously have smaller dust collection needs than I do.

I am still yet to see any decent studies into whether or not L-Theanine actually does anything at all. Studies never seem to find anything statistically significant, yet so many people swear by it. I'm inclined to say it is placebo.

Good recent writing on the topic: https://dynomight.net/theanine-2/

AFAIK highly depends on the person, I've given 1/4 or 1/2 doses to people and the most common reaction is that it is like a coffee. It seems the strong reactions are a minority of users. Specifically for me, I have long term dopamine dysregulation, so it hits really strong. Without the amitriptyline there is no way I could say on it.

I've also found that relying on agents to build their own context _poisons_ it ... that it's necessary to curate it constantly. There's kind of a <1 multiplicative thing going on, where I can ask the agent to e.g. update CLAUDE.mds or TODO.mds in a somewhat precise way, and the agent will multiply my request in a lot of changes which (on the surface) appear well and good ... but if I repeat this process a number of times _without manual curation of the text_, I end up with "lower quality" than I started with (assuming I wrote the initial CLAUDE.md).

Obvious: while the agent can multiply the amount of work I can do, there's a multiplicative reduction in quality, which means I need to account for that (I have to add "time doing curation")

> meme stock

Poor explanation since ~50% stock is owned by institutions.

I think retail holds 38% of ownership.

Rest of ownership is mostly Elon ~13%.

indexed fund ownership doesn't explain institutional holdings. Tesla is 5% of NASDAQ 100 by market cap. Vanguard owns 7.7%, BlackRock owns 6.4%.

> All currencies are manipulated. It's a meaningless statement.

That's probably (mostly) true today, but it wasn't always the case and it doesn't have to be that way. More importantly, just because most countries manipulate their currencies doesn't mean its meaningless to take issue with the practice or to notice when one country does it more aggressively than others.

I really don't think I need to cite a study that 5 years of time is a lot to give up on a company that goes nowhere. It happens! It's normal! And very painful. Which is why getting to a decisive resolution in 6 months is often a gift.

You will make more money, and probably work on equivalently interesting problems, working any other job than at a startup you cofounded that limps for years before winding down. It's really hard to see what upside you're finding here. I don't say this often, but this isn't a place I see leaving at "reasonable disagreement".

Because it's injected into a previously working product - even if it makes it worse - and automatically injects its ideas. That counts as "somebody using it".

Because it's bundled with other products that do provide value, and that counts as "someone using it".

Because some middle manager has declared that I must add AI to my workflow ... somehow. Whatever, if they want to pay me to accomplish less than usual, that's not my problem.

Because it's a cool new toy to play around with a bit.

Because surely all these people saying "AI is useful now" aren't just lying shills, so we'd better investigate their claims again ... nope, still terminally broken.

Who told ya that??

CDNA is 64 wide per work item. And CDNA1 I believe was even 16 lanes executed over 4 clock ticks repeatedly (ie: minimum latency of all operations, even add or xor, was 4 clock ticks). It looks like CDNA3 might not do that anymore but that's still a lot of differences...

RDNA actually executes 32-at-a-time and per clock tick. It's a grossly different architecture.

That doesn't even get to Infinity Cache, 64-bit support, AI instructions, Raytracing, or any of the other differences....

And where did the Mesopotamians move from? If you don't see the political context of the science then too bad.

Like, you know people till now take pride in the exploits and culture of their supposed ancient ancestors, never mind that for the the vast majority of people, there is no simple and direct line from some ancient illustrious people to them.

The latent political context is the assumption driving the research, that Egyptian culture had to have come from somewhere else, so let's go look for it. You see the same thing when evidence of cultural achievements elsewhere in Africa is unearthed.

Of course you will find a somewhere else, no matter how tenuous the connection, in which case my first sentence above comes into play: let's keep finding the somewhere else until we all get back to Africa, supposedly the birthplace of it all.

EDIT: Since this is being misunderstood, this what I actually mean: For some reason, this finding somewhere else is not applied consistently. Either we should keep finding the somewhere else for all cultures for as far back as we can, or else stop with this nonsensical subtext that just because a culture has some roots from elsewhere, so therefore it cannot have made innovations by itself beyond its supposed origins.

> reasonable baseline of appropriate

You're just prejudging the answer. Who wouldn't want reasonable and appropriate? The issue is that a lot of these platform-specific defaults are bad unergonomic legacy

Case in point: "Or if the window close button was in the wrong corner?" That would be great to have on any platform since it's a common UI mistake to clump categorically different buttons (non-destructive minimize and destructive close) together, thus raising the cost of a misclick

That's the main issue with your argument - yes, familiarity is a UI benefit, but the net benefit of following a UI convention depends entirely on said convention.

xor(1..n) = switch(n % 4) { case 0: return n; case 1: return 1; case 2: return n + 1; default: return 0; }

So you don't actually need the first loop (at least for the set of integers 1..n example), but bringing that up is probably out of scope for this article.

Interesting how I was reading an article yesterday talking about how cheese/dairy might give people nightmares, linked to GI distress and lactose intolerance.

It could be a factor that GI distress and food intolerances contribute to nightmares due to additional stress and inflammation within the body, causing premature mortality over the course of someone's life.

Something else: I support some long term clients still using some 1990s software that I've ported to run within a VM on modern hardware. I ended up using developer tools made in the 2000s to decompile the executable and make changes to the software, others have done so and posted their own version. These tools were not available when the developer walked away, so they probably never envisioned these changes.

With AI and other tools developing rapidly, I wouldn't be surprised if someone was able to do things with your code in ways you didn't expect, even if you choose not to open source it yourself.

The founder of SMIC(Zhang Rujing) was a manager from TSMC. He created SMIC not for money but for patriotism because he see himself as Chinese even he was from Taiwan. You can do some research on this guy, especially try to find some Chinese sources with google translation.

The western media has a narrative with many real evidence to support the narrative so most western people take it for granted. But the reality is more complicated. For many engineer money is an important factor for sure but maybe not all.

So it's a better Peltier element? The article only seems to compare it to existing thermoelectric devices and not standard refrigeration units so I'm going to assume they haven't gotten even close to that efficiency. If they had I would assume they wouldn't shut up about the fact.

Also one of the biggest if not the biggest downside of these chips is, unlike a split refrigeration circuit, the front gets cold while the back gets hot which means you can't move the heat very far.

Humanity routinely has a similar kind of ego that requires relevance. But fortunately we still have a distributed knowledge system that excises and corrects local folklore.

I don’t think it is interesting that there aren’t Egyptian scholars on the topic, whether this national/cultural identity existed or not.

I obviously don’t care if it bruises an ego, I would care if the lack of representation overlooks something though.
Show HN: I made an MCP Server to check whether domains are available
by elgertam | 2025-07-03 02:26:48+00:00
I'm terrible at naming things, so I ask Claude & ChatGPT to help me make domain names. Unfortunately, the chatbots lack the tools to query Whois or RDAP, and instead use web search. This has a lot of false negatives & could even risks certain less ethical registrars front-running the queried names if they don't exist.

Thus I fired up Replit and guided it to a working model context protocol (MCP) server that can query for domain names using RDAP and Whois. I built caching in to be respectful of the servers. It works and has really sped up my ability to find good domains

"What I see is a future where AI handles the grunt work, freeing us up to focus on the truly human part of creation: the next step, the novel idea, the new invention. If we don’t have to spend five years of our early careers doing repetitive tasks, that isn’t a threat, it’s a massive opportunity. It’s an acceleration of our potential."

The problem is that only a fraction of software developer have the ability/skills to work on the hard problems. A much larger percentage will only be able to work on things like CRUD apps and grunt work.

When these jobs are eliminated, many developers will be out of work.

What helped me grok the mathematical rigor is: If you have a series of monad operations that exist purely in monad world -- in Haskell, if your expression is parametric over the type of the monad -- you shouldn't have to worry about how you do it.

This is what monads being categorically commutative ("a monoid in the category of endofunctors") buys you. You want to turn monad X into monad Y? Sure, just join, flatten, return, bind in whatever way makes the type checker happy. Anything that only uses what's in the Monad typeclass must necessarily be a monad morphism, so if you're generic over your monads, you get that for free. And of course `fmap` and `bind` are required to be parameterized monad morphisms, so there's a lot you can get for free.

A parasite leaches off it's host to the hosts harm. Maybe it's not a good analogy, but Im in china, and it's painful after paying money for a VPN to bypass censorship to find myself routinely blocked by CDNs because they decided I'm not human. I'm honestly feeling more opressed by these middlemen than the government sometimes. For example, maybe I can't log in to a game due to being blocked by the login API, and the game company just responds by telling me to run an antivirus scanner and try again since they are not personally developing that system that lack awareness. Such people with genuine need for VPNs and privacy tools are the sacrifice for this system.

It seems misleading to say that this is "rendered in ASCII art"... more like the phase is being rendered, and it has an ASCII art moon background. If I copy and paste the moon text into a text editor, the phase is gone, so it's not actually part of the text.

And as others have pointed out, phases don't work like that.

If all the jobs doing research disappear because all the funding is cut, then what other choice to they have?

If one parent loses their job and cannot get a new one in their field, they have to either switch career (and start a new career at a lower point) or they take a longer-term view, assume that the other parent will also lose their job, and switch country.

> the virality of the GC makes it a non-starter for its primary audience (C/C++ developers)

No. If you were to say you need the GC to use all features of the language and standard library, of course, the GC does important things, but to claim a C developer wouldn't be comfortable with it because of the GC is nonsense. Just don't allocate with the GC and use the same mechanisms you'd use with C (and then build on top of them with things like @safe, reference counting, and unique pointers).

Chinese stocks are pretty reasonable right now, if their market has dealt with the insider trader mess then it might be a good time to onboard. It isn’t for the feint of heart however.

Markets used to be places to make money more smart (efficient allocation of capital) but have somehow degraded to index fund buys that track average economic growth of a few hot stocks that are expected to at least not get cold anytime soon.

This is true, but it seems a lot of the manufacturers stop making interior parts, trim, electronics, etc. for cars older than 8-10 years.

Need a seat, mirror, air conditioner vent trim, logo for your trunk, floormats? No luck with most manufacturer... and these are the kind of parts the 3rd party supplier market doesn't even attempt to do.

I still have a warranty (factory) on my other German car, but even though it is only 7 years old they do not stock or make a replacement for the hybrid battery. So even though it failed and is under warranty, the manufacturer cannot fix it. This has been ongoing over 11 months now; apparently it wouldn't happen with Porsche

I'm afraid google's search and AI bots are the same. Either get both or none. None means no visibility in web. Some will be fine with this, but most will agree on AI bots to get visibility. Soon AI providers will charge those who want to be included, if they don't do it yet. With this on request they'll return preferred products and services. Just another form of hidden advertising.

I haven't had an useful meeting in years. All the important collaboration and decision making has happened organically in text chat, which is great because it's all searchable and dated, and I do refer to that a lot. In fact they recently moved my main collaborator from another building into the next desk and we agreed to keep the work stuff in chat as much as possible so it isn't lost. So we chitchat about our kids but still type out our debate about the best version launch date.

Every meeting in person or via Zoom I have been in has been either an useless sales pitch, grandstanding by some manager, brown-nosing by some upstart or some other form of toxic socialization, scheming or conspiracy. I detest all those and avoid them, which is probably why I've become kind of an unpromotable pariah, which is ok, as a promotion would mean attending more of them.

It gets worse: I have done tech support for clinics and a common problem is that their computers get hacked because they are usually small private practices who don’t know what they don’t know served by independent or small MSPs who don’t know what they don’t know. And then they somehow get their EMR backdoored, and then fake real prescriptions start really getting filled. It’s so much larger and worse than it appears on a surface level.

Until they get audited, they likely don’t even know, and once they get audited, solo operators risk losing their license to practice medicine and their malpractice insurance rates become even more unaffordable, but until it gets that bad, everyone is making enough money with minimal risk to care too much about problems they don’t already know about.

Everything is already compromised and the compromise has already been priced in. Doctors of all people should know that just because you don’t know about it or ignore it once you do, the problem isn’t going away or getting better on its own.

The problem is not that they are fooling anyone. No one thinks a woman is marrying a chimpanzee. The problem is that the videos are obviously and openly racist and being spread quite brazenly.

If I have to encounter a constant barrage of shitty racist (or sexist, or homophobic, or whatever) material just to exist online, I'm going to pretty quickly feel like garbage. (If not feel unsafe.) Especially if I'm someone who has other stressors in their life. Someone who is doing well, their life otherwise together, might encounter these and go, "Fucking idiots made a racist video, block."

But empathize with someone who is struggling? Who just worked 18 hours to make ends meet to come home and feed their kids and pay rent for a shitty apartment that doesn't fit everyone, and their kid comes up to them asking what this video means, and it just... gets past all their barriers. It wedges open so many doubts.

This isn't harmless.

>The lack of any Egyptian archeologists on most interesting and significant findings about Ancient Egypt is one.

It seems like Egyptian archaeologists is a clique of academics that do not like to rock the apple cart and go against established ideas about Egyptian history. There is a lot of gate keeping going on, mostly in part of Zahi Hawass, a narcissist that likes to self insert into every research into the subject, and control publication of results, etc. Even worse, claim attribution for work he's not even part of. So, if you don't kiss the ring, or dare to challenge ideas without his blessing, you'll be pretty much become a pariah that will never access archaeological sites again. Because of this, research in the field seems to be stagnant.
