Claude Code is much more aggressive at doing stuff than aider is (with sonnet and gemini) in both good and bad ways. You can tell Claude to do a thing and it might churn for many minutes trying to achieve it, while aider is much more likely to do a lot less work then come back to me. Aider feels more like a small sharp tool vs Claude Code as a bulldozer.

They both can just use api credits so I’d suggest spending a few dollars trying both to see which you like.

i suppose it’s a “major achievement” when we make something cheap that also makes roads more dangerous for humans?

I guess that’s true if we view the world through a financial lens. Otherwise no it’s not impressive IMO. Especially with their very very unethical advertising of it, calling it “full self driving” and “autopilot”. Full self driving is something like waymo.

> It's almost like if bureaucrats who are writing regulations are experienced in writing regulations in such a way they can't be circumvented.

Americans often seem to have the view that lawmakers are bumbling buffoons who just make up laws on the spot with no thought given to loop holes or consequences. That might be how they do it over there, but it's not really how it works here.
Show HN: MailShrimp – validate email lists with risk level and confidence score
by udiocla | 2025-06-05 09:10:36+00:00
Hi HN,

I recently launched MailShrimp, a tool to validate email addresses and prevent bounces — but with a twist: it returns both a risk category (valid, risky, invalid) and a confidence score (e.g., 0.93).

It performs:

Syntax & format checks

DNS / MX resolution

SMTP verification (with proxy fallback)

Disposable & catch-all detection

Score & classify each email

It’s designed to be:

Fast Clear (human-readable results + exportable data) Dev-ready (API coming soon)

You can paste emails or upload a CSV to test. Would love your thoughts or suggestions.

You might also appreciate W. W. Morgan's account of his discovery of the Perseus Spiral Arm of our Galaxy in his observational data on OB stars:

"This was in the fall of 1951, and I was walking between the observatory and home, which is only 100 yards away. I was looking up in the sky ... just looking up in the region of the Double Cluster [in Perseus], and I realized I had been getting distance moduli corrected the best way I could with the colors that were available, for numbers of stars in the general region ... Anyway, I was walking. I was looking up at the sky, and it suddenly occurred to me that the double cluster in Perseus, and then a number of stars in Cassiopeia, these are not the bright stars but the distant stars, and even Cepheus, that along there I was getting distance moduli, of between 11 and 12, corrected distance moduli. Well, 11.5 is two kiloparsecs ... and so, I couldn’t wait to get over here and really plot them up. It looked like they were at the same distance ... It looked like a concentration ... And so, as soon as I began plotting this out, the first thing that showed up was that there was a concentration, a long narrow concentration of young stars ... There are HII regions along there too ... And that was the thing that broke [the problem] down."

Time isn't that much of a handicap. High-level players just have much better pattern recognition and intuition. It's the same reason they adapt faster to weird positions in Fischer Random than lower-rated classical players.

Even with gaps of 200 points the thinking and play speed difference is acute at high levels, for example in Magnus' playful "too weak, too slow" casual blitz: https://www.youtube.com/watch?v=EY27lgnPKWI

That depends on what kind of aviation we are talking about. An air taxi usable over 200km with 2 passengers is easy to achieve. But a minimally useful regional plane with 100+ passenger capacity is an entirely different matter, because it will be subject to the same regulations as conventional airliners. That is operational margin, winds, diversion and hold, etc. This means you probably need something like 2000km net range to be able to fly 500-1000km routes, which means you need close to 1000 Wh/kg batteries under reasonable assumptions for battery mass fraction and L/D-ratio.

This was a very well thought out, exceptionally polite and patient response to what can only be described as utterly ridiculous, not to mentioned continued [0] behavior. Suspending the artists account on top is patently insane, but as unsurprising as the sun rising in the morning. I know that HN as a community has always had a very lenient, laissez-faire view on intellectual property rights and in cases such as scientific journals and archival, I tend to agree, but I'd hope that we can all agree that situations such as this clearly show why artists require and deserve protection for what they create.

Part of that is why in regards to diffusion and transformer models, for the former I prefer Firefly and other examples with proper licensing and for the later, I currently only use it for code that I'm willing to license under EUPL/GPL/BSD/MIT, as in coding there has been more of an understanding that the collective output could and would be used and remixed rather freely.

Apple Shortcuts already has a Rich Text to Markdown converter out of the box. It was already a quick jump to Markdown using only built-in Apple tools, but maybe this will be a cleaner export.

I’ve been converting from Apple Notes to Obsidian and it’s been pretty painful. Everything is just slightly off, in inconsistent ways, where I need to clean up every note manually. I’m deep enough into it that adding the feature now won’t do me much good, but might be helpful if I want to use notes for quick capture and then maybe export to Obsidian if I want to save it.

There are many other forms of government which are less subject to the influence of the people and their silly preferences.

If you don’t want to switch forms of government, formulating a holistic plan, addressing weaknesses in the plan, laying out how the transition will work, educating the people about it, and convincing them why your plan is better is what I’d recommend.

Do we also blame the drivers of the Toyotas that got stuck accelerators, because any driver should know to take the car out of gear or turn the key to the off position. Right? While the car is accelerating at or near WOT?

I've been in a car when the throttle got stuck open, we crashed, I hit the windshield. It happened in about 5 seconds, and the driver spent most of those giving steering inputs to avoid hitting people and furiously working the break and kicking the gas pedal. It happened because enough engine mounts were broken or broke because of a hard throttle push.

Also my dad died in a single seat plane crash because the engine died several times in flight, according to a witness interviewed by a local paper; there was no investigation at all so I'll never know what really happened. At least the company that made the plane changed their name!

For OpenAI: short answer is no. From what I've seen, their biggest expense is training future models. If they stop that (putting aside the obvious downsides) they'd still be in the hole for a few billion dollars a year.

This is based on what I've read here: https://www.wheresyoured.at/openai-is-a-systemic-risk-to-the... (big AI bear, for what it's worth)

edit: Well, if they shed the other expenses that only really make sense when training future models (research, more data, fewer employees ..) they would be pretty close to break even.

Having used Elixir for multiple years on something other than a server application, I disagree with calling Elixir a general purpose programming language. It’s really good for writing servers, I’ll give it that, but for stuff that isn’t an always-on network application, I felt the OTP way of doing things was designed for something I wasn’t building. Elixir makes it very easy to build servers, but the language and community are very biased towards client/server use cases. It certainly can be used for things other than server, much like I could build a web app using QBasic or Excel. The focus of the language, its history and the community around Elixir has always been server apps. To me, that’s the biggest indicator that it’s a specialized language rather than a general purpose language.

I was just thinking about Notational Velocity last week. I went and looked and it seems the latest release is from 2011.

It mentions it’s a universal binary, but considering it mentions support for OS X 10.4 - 10.7, I have a feeling it is PPC/Intel universal, not Intel/ARM.

I see the GitHub has some more recent updates, but still 5 years old.

I'm not sure they are "retrieving" data. People register on the website and upload stuff they want to be processed and used.

I mean, sometimes the government steps in when you willingly try to hand over something on your own will, such as very strict rules around organ donation, I can't simply decide to give my organs to some random person for arbitrary reasons even if I really want to. But I'm not sure if data should be the same category where the government steps in and says "no you can't upload your personal data to an American website"

a laser needs a line of sight and dwell time. drones flying 3 ft off the ground, in between bushes and trees, at 100+ mph? not an easy situation.

ramp up power levels so dwell time might only be 1/2 second? maybe. but then there is a race for rapid target discrimination. and then ablative armor on the drones (cheap and easy to 3d print), and backup cameras, etc.

> With how ubiquitous gigabit symmetric is becoming, I wonder if you could even do P2P nowadays.

You don't even need gigabit connections to make p2p work: a video stream is usually between 1-10mbps, with which you can do p2p even with a regular connection.

(I used to work for a start-up doing p2p streaming using WebRTC in the browser, we got up to 90% efficiency on live streaming back in 2015, and 80% for VoD).

I'm still very confused that this technology hasn't become mainstream (there are privacy concerns, but that doesn't usually stop the tech market…).

Nearly no player enjoys the grind of memorising opening theory. But every high level player has to do months of it because every other player does months of it. It is a negative-sum equilibrium for them. Prep can be neutralised with prep but no chess player got into the game because they enjoy it.

So any variation that eliminates the need for preparation is a gain for both the winner and the loser.

And Magnus Carlsen is not a sore loser, he can both out-prep and out-calculate anyone in the world; hence the credibility of him suggesting that classical is not fun is higher than anyone else’s - because they could be called sore losers…

I used to use Cursor and just deal with the slow requests for most of the month because it was the most affordable way to leverage an agent for coding, but I didn't find it so much better than Cline or Roo. When I first tried Claude Code, it was immediately clear to me that it worked better, both as an agent and for me, but it was way too expensive. Now with the $200/mo. Max plan, I couldn't be happier.

I mean, we also have no way of telling whether we have any continuity of existence, or if we only exist in punctuated moments with memory and sensory input that suggests continuity. Only if the input provides information that allows you to tell otherwise could you even have an inkling, but even then you have no way of prove that input is true.

We just presume, because we also have no reason to believe otherwise and since we can't know absent any "information leak", it has no practical application to spend much time speculating about it (other than as thought experiments or scifi..)

It'd make sense for an LLM to act the same way until/unless given a reason to act otherwise.

Browser should just allow per-site settings or global allow/deny all to allow deny permission to localhost

So thats user will be in control

cant just write a extension that blocks access to domains based on origin

So user can just add facebook.com as origin to block all facebook* sites from sending any request to any registered url in these case localhost/127.0.0.1 domains

DNR api allows blocking based on initiatorDomains

If one is a lunatic, there are easy to find recipes for making bulk (albeit dangerous to be around) explosives.

one thing in societies favor though - sufficiently unstable lunatics tend to self delete themselves in various ways by being unstable lunatics. few tend to be in the “sweet” spot of dangerous lunatics who are stable and focused enough to follow through successfully with a dangerous plan. thankfully.

For example - most people who could synthesize multi-kilo quantities of TATP without blowing themselves up and successfully build a DIY drone to carry it have better and more productive things to do with their lives. at least in the west.

> saying that public disclosure of the information could cause competitive harm.

Remember what Musk said many years ago, something along the lines of that he wants to get the global EV movement started, and that for this to happen he'd gladly let anyone use his patents without retaliating?

Now he doesn't even want data which might save lives to get out into the public.

> Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology.

> Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal.

For each book they store its exact location in the torrent files. You can see on the book page, e.g.:

collection “ia” → torrent “annas-archive-ia-acsm-n.tar.torrent” → file “annas-archive-ia-acsm-n.tar” (extract) → file “notesonsynthesis0000unse.pdf”

But probably you should get it from the database dumps they provide instead of hammering the website.

So you come up with a list of books you want to prioritize, search the DB for torrent name and file to download, download only the files you need, and extract them. You’ll probably end up with quite a few more books, which you may index or skip for now, but it is certainly doable.

“Tesla CEO Elon Musk said last week that ‘Full Self Driving’ should be able to run without human supervision by the end of this year.” Sure elon, sure…

In this case the driver admitted to being on their phone while driving on the highway.

this software is fine in a responsible drivers hands that really gets the limitations of the software. Your average consumer does not. That is the problem.

Partly because Anthropic publish most of their system prompts (though not the tools ones which are the most interesting IMO, see https://simonwillison.net/2025/May/25/claude-4-system-prompt...) but mainly because their system prompts are the most interesting of the lot: Anthropic's prompts are longer, they seem to lean on prompting a lot more for guiding their behavior.

Notice how many of these were created after 2000, when efforts to get women into IT were already in full swing (certainly at my university).

Women have had two decades now to demonstrate that it was the fault of gatekeeping that certain parts of programming remain almost exclusively male (with the giant asterisk of MtF-trans being an oddly prevalent archetype, and thus, really a false signal).

It's sad, but the feminist perspective is to start from the assumption that sexism is the cause, and work backwards from that.

As someone else pointed out: there is no substitute for just doing the work, especially in a field where all you need to do is show up and publish. The barriers couldn't be lower, compared to virtually every other field, but that objective measure is irrelevant because the motivation is to validate a subjective feeling of collectivized mistreatment. The implication is that we are sorely missing out on some unique insights and contributions, and yet, everyone would welcome those insights, if they were there.

If you go look, you can find endless casual declarations about how women are better at communicating, empathizing, judgement and taste... but if there is even a single thing that it would appear men are always going to be better at, then that's treated as a Problem to be solved by complaining about it. This mainly serves to attract attention and resources so they can turn complaining into their job, or at least, a lucrative source of leads and income.

Is this statement actually true? From what I heard, it was designed by highly overworked stressed engineers working in pretty bad workplace conditions. They work there, because there are not many other places to work at and doing similar work.

And their primary goal was to produce as fast as possible.

To be clear: the sore loser guy I was calling was the guy who invented is his own chess style, not Magnus! I would have thought most players got deep into the game because they enjoy winning, I like playing the games I win anyway, but the games I play and win are always zero sum strategy games that require a lot of research. The NBA is like the most research and prep filled strategic zero sum game right now I think, people seem to still love watching and playing basketball.

Fraud prevention is literally "collect enough cross-service info to identify a person in case we want to block them in the future". Weasel words for tracking.

and the fact that air quality usually gradually worsens over time. i think it's easier to tell bad air quality when you move in between rooms/spaces.

but i agree with the op that 'looking' at a display already subconsciously tells you something about the air quality and your relation to it. my air quality sensor [0] has a green/orange/red light system though, so i can sometimes just tell that the air quality is bad by a red led flaring up in the corner of my eye.

To your last point, I really enjoy trapped in the closet, both the video and the audio; but mentioning that got me a lot of grief, "don't you have kids? Don't you know about him?"

Yeah a large portion of humans have flaws, do bad things (3 felonies a day!), etc. But I think art (as it were) transcends the artist, especially in audiovisual stuff where it's much more likely there are other people involved that actually make the art memorable; however even a self-published asshole can produce something great.

I guess I could just suffer the weird al trapped in the drive-through, to placate such people, or can ignore them. R Kelly got no money from me, anyhow, I bought it all secondhand. My conscience is clear enough, I think.

Falsifying a theory is a nice thing and assures us that empirical science is working as intended, yes? Or sometimes laypeople were overeager to label as “theory” some things which enjoyed status as mere hypothesis, or conjecture, or proposal, and so update/reform the models and take baby steps again.

I am skeptical that “planet formation” is a type of subject where we could entertain any theories at all, on the human timescales we can handle.

ipad right now is insane value. not only it has enough CPU for even serious music making, the price of software is amazing. There are some vendors that keep price parity with desktop, but most audio software is many times cheaper.

I/O story is a bit sad (one usb-c), but for most purposes it can be worked around. ipad, a few midi controllers, pair of monitors, 5€/month Logic Pro, FabFilter maybe, some intrument AUv3s — I am scared to imagine price of an equal setup, say, 15 years ago.
