It's mainly from experience. From when I set it up I didn't have the feature to ask whether to run commands. It has been rawdogging commands this whole time and has never been a problem for me.

I think we have many other users who are similar. To be fair, sometimes after watching it install packages with npm, people are surprised and say that they would have preferred that it asked. But usually this is just the initial reaction. I'm pretty confident this is the way forward.
Unfortunately is pretty far from "less than 10 years", which I guess you got from the half life of tritium. Tritrium radiocativity, in the form of tritium retained in the plasma facing materials, does contribute in that order of years if done properly, but neutron activation dominates and it's unavoidable. The actual numbers are in the order of hundres of years, still a lot less than fission high level waste, but let's not make unreasonable expectations around fusion, please.

You can find here a good comparison in terms of radiotoxicity vs years after plant shutdown for a few designs in this article [1].

SpaceX was able to re-fly a Falcon 9 in 3 weeks, and it was reported[0] that the refurb process only took 9 days. So they're well on their way.

It's also worth noting that Booster (the first stage), Starship (the second stage) and Raptor (the rocket engine) were all designed with the benefit of the above experience and with the goal of same-day reuse in mind. They know where all of the refurb time went and where the bottlenecks are.

I have no doubt that they can reduce the turnaround further, but the goal of same-day re-flight does seem mighty ambitious.

I won't argue that Spotify isn't a fantastic value, but the price has gone up and will continue to do so (especially if artists are ever going to make anything meaningful from streams), and nothing lasts forever..

I find that online services in general degrade and become worse values and experiences for users over time, nearly inevitably. In many cases because initial funding can help to support the early unsustainable pricing.

I guess I'm saying it's good to have a downloaded backup of the all-time favs while using spotify for convenient listening.
It wasn't under $1k but you can do some options for close-ish to that: a cargo e-bike.

It's been amazing and has let us remain a one car family despite two kids with a lot of activities. I adore it. About to hit 2k miles on it.
SkipScan Under Load
Hi HN!

I wrote this article comparing TimescaleDB's SkipScan feature to vanilla Postgres performance for DISTINCT queries (get me the last row for all IDs) while a 200K rows per second ingest was happening.

I'm going to be writing more of these smaller performance pieces (sometimes Timescale related, sometimes Postgres related) - I'd love to hear some suggestions (especially around PG performance) from the HN community
Under 1000:

- robot vacuum. Now my house gets vacuumed (that should tell you how much I hate doing it.)

- the bidet seat is not tremendously life changing but it's very helpful.

Under 100:

- a quality probe thermometer. I use it for everything baked and most ways of cooking meat. Nothing is over~ or undercooked anymore. I do have another one with 2 probes for bbq/smoking -- you can use the two in the point and flat of a brisket, which tend to cook to different temperatures, or use one to monitor temperature of the grill and the other for the meat. It's also bluetooth so I can monitor temps from the comfort of my computer desk.

- a good rice cooker. Frees up a burner, rice is done when you tell it to be done and it's always perfect.

Pretty easy to add runtime validation at the edges with Zod https://github.com/colinhacks/zod

Great thing is that the zod schema also doubles as your typescript type so you don't have to write a duplicate/shadow TS type definition.

This or: God is an egg.
The dems failed at messaging, as they have forever. Both parties have abdicated their role enforcing antitrust regs (esp as it relates to the food industry).

Additionally mis-handling COVID and implementing a 25% tariff on some commodities had a massive impact on prices.

Then there’s just the evolution of some markets: PE buying housing inventory + short-term rentals + Rental yield-management (thinly-veiled collusion on pricing) have transformed the housing market.

The biggest impacts: consolidation and a deregulation mandate. Companies can do whatever the hell they want.
What if you have a microservice system with a repo-per-service setup, where to add functionality to a FE site you would have to edit code in three or four specific repos (FE site repo + backend service repo + API-client npm package repo + API gateway repo) out of hundreds of total repos?
"cheap consumer paper printers and hard drives" was not a 1970s thing.

I mean, towards the end of the decade was something like the ImageWriter, which let you do bitmapped graphics, as a row of 9 dots at a time. At https://www.folklore.org/Thunderscan.html?sort=date you can read about the difficulties of turning it into a scanner. (Like, 'We could almost double the speed if we scanned in both directions, but it was hard to get the adjacent scan lines that were scanned in opposite directions to line up properly.')

The LaserWriter wasn't until 1985 or so. My first hard drive, 30 MB, was a present from my parents around 1987.

By the 1996, laser-based 3D printing based on cutting out layers of paper was a thing, available for general use in one of the computing labs in the university building where I worked.

The result smelled like burnt wood.

When I visited a few years later they had switched to some other technology, and one which could be colored, but I forgot what.
How is this compared to using gpt-4 directly?
Has anyone seen info on how this works? "It’s not revolutionary" seems like an understatement when you can do better then DeepL and support more languages then google?
I'm not sure what you mean by classification, but something like it, yes:

Show HN: Draw.Audio – A musical sketchpad using the Web Audio API
Hello HN community!

Out of my love for synthesizers and web development, I created a free audio sequencer called draw.audio, which includes selectable scales, waveforms, effects, LFOs, and more.

While there are other “tone matrix” style webapps out there, I couldn’t find one that quite scratched the itch for a large grid layout, modern design, and easily accessible modulation controls. So that was the inspiration, alongside my addiction to synths and hardware jam-boxes like the Synthstrom Deluge.

Draw.audio uses the Web Audio API without any other frameworks or libraries. I tried to keep it as lightweight as possible. The to-do list includes a tutorial, pattern preset browsing, more audio effects, light visual animations, and open-sourcing it.

In case you'd like tips:
• It’s more fun on touch screens, like an iPad.
• It's kid friendly! In my limited testing, kids enjoy drawing on it.
• The share button generates a direct link to anything you create.

A big thank you to Sheer Havoc for creating the logo and other graphics!

And thank you all for checking it out! I’d love to hear any feedback you have. <3

Under $100: A used Instantpot, ideally the Duo Crisp if you can get one. The normal one can also make yogurt though, which might also be interesting. The great thing about these is that you don’t need to babysit them. Have a call or wanna go for a walk, and then eat? Just turn it on and come back anytime after it’s done. It will keep food warm until you turn it off. Bonus tip: Buy two and/or an air fryer to get more options, eg veggies in one and protein in the other.

Under $100 #2: Get a CGM for two weeks and find out what foods spike your blood sugar the most. Or what supplements can help keep it steady (eg vitamin B1, inositol, or Chromium). Say goodbye to food coma and likely improve your long term health.

Under $1000: Get a second freezer. From that point on you can buy frozen veggies etc during sales, and prep meals during the weekend, for the whole week. I don’t know how we got by with just one tiny freezer section in the fridge.
> They are the brains of a ton of cars on the market, like all Ford cars. Used for complex calculations like automatic transmissions.

I would seriously doubt that QNX or anything like it resembling a "real OS" is running on the automatic transmission. If the transmission controller is running any OS at all it's likely a microcontroller running a much more specialized RTOS.

QNX is very common in automotive applications, but in things like digital instrument clusters and ADAS where the software is complex enough to benefit from a full networkable OS with support for a lot of different high speed buses but the use case still needs real-time guarantees and/or microkernel stability. I've specifically seen QNX's hypervisor marketed for digital clusters where the critical data display and interaction with the ECU could happen within a fully certified QNX environment that would be designed to be as stable and reliable as possible while allowing infotainment applications to run in a VM instance of Android, Linux, or even more QNX where software reliability was less critical. If it crashes, the important instruments are still working.

Ford's "Sync 3" and "Sync 4/4A" infotainment systems run on QNX as well, though being just infotainment they didn't really care about the realtime aspect (though I'm sure stability was a big thing compared to their Windows CE based predecessors). They've moved to Android for their latest revision.
As much as DuckDB is cute I've mostly come to believe that Clickhouse is the perfect thing to pair Postgres with. This is especially true now that they've acquired PeerDB and are integrating it into the Clickpipes cloud product.

DuckDB is neat, and I understand why a company like BemiDB would build their product on top of it, but as a prospective customer embedded databases are a weird choice for serious workloads when there are other good open-source solutions like Clickhouse available.
Matrix is described as a distrubuted graph database. Chat is just the most common use case, but there are others.

Cool, it's probably about the same, since we're both using the new Sonnet 3.5 for coding.

We might have a bit of an advantage because we pull more files as context so the edit can be more in the style of your existing code.

One downside to use pulling more context is we burn more tokens. That's partly why we have to charge $99 whereas cursor is $20 per month.
I’m against protected class laws and I am for accepting reality and making public policy based on that reality. It is just my view that social media is unhealthy at any age.
The old (maybe incorrect) advice I was always told was that continuing to heat the coffee fouled the taste, hence the recommendation to use an insulated mug/thermos as opposed to a Mr. Coffee style warmed carafe. What makes this gadget different/better?
It should still have the same impact at scale, right? ie if I had a server handling enough WebSocket connections to be at 90% CPU usage, switching to a protocol with lower overhead should reduce the usage and thus save me money. This is of course assuming the system isn't io bound.
Self driving cars and cheap tunnels can solve this. Hopefully that happens some days. People are working on both (a lot less on cheap tunnels).
This is the wrong approach, to achieve the desired effect they should make social media compulsory for anyone over ~40.
>The problem as I see, given a choice, people rather eat/do/listen/feel things that they want, not the things they’re being forced on. In the past, you didn’t really have a choice and was forced to do what everyone is doing. Now, to live in such communities, you’ll have to get rid of the choice. Which also sucks.

In the communal situations you have choice. You prepay for the food per month and it works like a buffet. So to save money you should eat what's provided. But you have choice to forego it. This is very typical of dorm life in colleges and it leads to really close bonding with everyone on the floor.
By this logic anything meaningful anyone does is actually done with C, because no matter what you do there is 40 million lines of kernel code underneath...

Yes but that's not what my complaints about the FTC are. My complaint is about them trying to stop Microsoft from buying Blizzard or trying to stop Adobe from buying Figma. I don't believe there's such a thing as 'monopoly on video games' or 'monopoly on website design software'.

Them working on general, consumer-friendly, sane policies is fine! But they shouldn't be preventing M&As/investments unless critical goods are involved without a substitute - which Call of Duty and Figma clearly aren't.
I think they're suggesting that highly popular sites like ChatGPT get a ranking boost beyond regular page rank, making SEO efforts unnecessary.

But I don’t think that’s the case, at least not artificially. These sites tend to rise naturally in search rankings because they have a huge volume of links and media coverage. Which still makes SEO efforts unnecessary.
Disclaimer: I am already a Kagi customer.

At least for Afrikaans I'm not impressed here. There are some inaccuracies, like "varktone" becoming "pork rinds" instead of "pig toes" and also some censorship ("jou ma se poes" does NOT mean "play with my cat"!). Comparing directly against Google Translate, Google nails everything I threw at it.

I didn't see any option to provide feedback, suggested translations, etc, but I'm hopeful that this service improves.
Yes, that is true! Koka's constructor contexts also allow you to do this. A constructor context is a data structure with exactly one hole which you can fill in with an arbitrary value (or even several arbitrary values, copying the constructor context in the process).
Beeper (built on matrix) has convenient bridges to lots of services. You can use the hosted service or self-host (https://github.com/beeper/bridge-manager) or you can host plain matrix using https://github.com/spantaleev/matrix-docker-ansible-deploy/
I feel like Edge is more acceptable; running at a PoP is close to the edge; running inside an ISP network is even closer; it's not really achievable, but running in ISP managed modems or cellular base stations is pretty much the limit of plausible Edge computing.

Serverless really should mean the client does the work, but it seems pretty equivalent to shared hosting. Dreamhost (and the shell account you used to get with an ISP!) was serverless before it was cool?
Presumably your language has a package manager which can do that for you? (or you could distribute it as an image). I guess you do have to decide which version you should depend on, but putting that power in your hands is sort of the point.
It's strange that all the closed models whose mentioned reasons for being closed is safety is allowing this, and banning the apps which allows for erotic roleplay all the time. Roleplay is significantly less dangerous than full shell control.
At least in France you can get a Nespresso machine "for free" of you buy enough coffee for a year (a very reasonable amount).

> Putin doesn't have a say in other countries

Im pretty sure all imperialists have a say what happens in other countries. US does it kn a regular basisneven to allies. It is kind of in the definition of the term. This is not about morality of it. I am saying it was down right stupid not to have expected Russia to attack while the country was taking serious steps toward inviting NATO in its borders. Anyone with a brain could have predicted how Russia was going to react toward this. The US tried to pull a bluf but honnestly they couldnt care less since they are on another continent

> Ukraine can join NATO if they choose to.

I mean, that is obviously false as things stand right now

It will hold my coffee at the perfect temperature all day. Also if the battery runs out I can put it on its charger and after ~5 mins it will start heating my now cold coffee back up to temperature. I thought it was kinda gimmicky too before I bought it but I am surprised at how great it is to have perfect temp coffee all the time.
This does seem to be suited to monorepo.
Running/jumping/hunting/scavenging:Vertebral mobility&backbones in carnivorans
That's a nice take if you completely ignore what Trump has said over the past 8 years about multiple generals including Mark Milley and Jim Mattis.

Insinuating that they should be put to death, personal insults, etc.. all because they did things he didn't like. I would recommend searching for the rhetoric used using the two names I mentioned above. You probably don't care, but both have come out and said he's a threat to the constitution and a fascist.

Seems weird that conservatives would be okay with trashing top military brass in that manner.
Many on HN have likely benefited just like you.

This country is rule by law, the laws regularly broken will be weaponized for political purposes.
The magic ingredients were inexpensive microcontrollers, massively paralleled mosfet transistors (also a product of large scale integrated circuits, since they are actually millions of tiny mosfets working together), and the expiration of several key patents that made it possible to have a commercial explosion around the reprap scene.

The patents expiring was a big deal, since the main patent was on the fused deposition process itself.

The other factor was that normal desktop computers had become powerful enough to run sophisticated 3d modeling programs and make machine motion computations from 3d design files.

"The dystopian bit is the corporation having this data."

I find data collection and tracking disconcerting not because I'm doing anything nefarious, unlawful or something I'm ashamed of—my life is pretty boring and uninteresting—but because it has the effect of reducing one's autonomy. If one knows one's data is monitored and one is being tracked then one acts differently. For some, they'll make minor changes in behavior, for others a lot. Even for those who've no idea about others tracking or collecting data about them there's the broader issue of how society ought to be conducted. That's a very big issue I can't address here.

Of course, the authoritarians amongst us would argue that monitoring is good thing as people won't be tempted to misbehave, commit crimes and such. I'd answer that by saying those who've nefarious intent will find ways of circumventing the surveillance so the net effect on society is negative as the 'innocent' are the onrs who are targeted without a good or just reason.

Right, pretty much everyone has a mobile phone. What has truly surprised me is how many people are prepared to trade data and being surveiled for convenience. I often wonder if they make such conscious decisions knowing the full implications of that surveillance. I suspect most do not.

Having a mobile phone it's inevitable I will be tracked by multiple entities from government to Google. My response is governed by how much I am prepared to trade privacy and autonomy for convenience and I reckon that's a large amount. Not having Google account and killing and or removing all Google services goes some considerable way but I'm under no illusion that Big Tech is still tracking me. That said, the info colllected wouldn't hold much value.
Please elaborate. Why? What is it using now?
You could buy a 3-D printer from Stratasys in 1990, but it cost $178,000! The printing unit was $130,000 and the Silicon Graphics workstation with slicing software to run it was $48,000 more. So the technology was there, but two orders of magnitude too expensive for the consumer market. Patents account for part of the cost, but the computer to control it was also way too expensive, as well as the custom (vs commoditized) mechanical components.

Great question – we struggled for a long time to put our demo together precisely for this reason. Codebuff is so useful in a practical setting, but we can't bore the audience with a ton of background on a codebase when we do demos, so we have to pick a toy project. Maybe in the future, we could start our demo with a half-built project?

Hopefully the demo on our homepage shows a little bit more of your day-to-day workflows than other codegen tools show, but we're all ears on ways to improve this!

To give a concrete example of usefulness, I was implementing a referrals feature in Drizzle a few weeks ago, and Codebuff was able to build out the cli app, frontend, backend, and set up db schema (under my supervision, of course!) because of its deep understanding of our codebase. Building the feature properly requires knowing how our systems intersect with one another and the right abstraction at each point. I was able to bounce back and forth with it to build this out. It felt akin to working with a great junior engineer, tbh!

EDIT: another user shared their use cases here! https://news.ycombinator.com/item?id=42079914
Yes. Natively, the models are limited to 200k tokens which is on the order of dozens of files, which is way too small.

But Codebuff has a whole preliminary step where it searches your codebase to find relevant files to your query, and only those get added to the coding agent's context.

That's why I think it should work up to medium-large codebases. If the codebase is too large, then our file-finding step will also start to fail.

I would give it a shot on your codebase. I think it should work.
