Piggybacking onto this comment, but another reason for external pours is thermal performance. A copper pour on the surface on the PCB allows heat to convect off the board more easily. The gains aren't massive, but they can help as part of a larger thermal management scheme.

I've also heard, possibly apocryphally, that in the old days when we used harsher chemical etchants, removing all of the copper from unused sections of the PCB would increase the risk of thinning the traces beyond what was intended. So in those cases a copper pour would reduce the time the PCB would need to spend in the etchant bath.
Would be interesting to see what other datasets are available for measuring bias
First SmallTalk versions were built with Lisp. “Live environment” and “world image” were just inherited.
Relevant similar behavior.
Algorithmic feeds are pure poison for the mind.

But what might be even worse is headline reading. Like you don't read articles like you use to. People read the headlines which are rage bait and click bait. Realtime rage on "developing stories" than nothing when the boring conclusion is known weeks later. People are going insane.

The death of the boring news paper is about as a big problem as Instagram. Modern newspapers just plainly sucks and are mostly rehashes of agency news anyways.

I think we need to figuratively pull the plug on the internet. Like make it some sort of loser thing to be hooked on social media and light minded news.
I refer you to the title of the submission, my good man.
I do that as well and also in almost all my personal documents on most (but not all) topics. All the books and most online forums I read are in English. I rather have documents uniformly in Swedish English (en-SE?) than some Swenglish mess of Swedish mixed with English words.

It also helps on the rare occasions some random notes evolve into a proper project that will have to be in English eventually anyway. There is no need for an extra translation step between initial idea and final product. All my vague hobby gamedev ideas are in English for instance.

You said "they're losing the race." They might lose, but I don't think we're seeing that yet. They undoubtedly gained a competitor over the weekend, but that didn't change their position as the leading AI company overnight.

Correct me if my understanding is wrong, but if OpenAI's accusation is correct and DS is a derivative work, then isn't it inaccurate to say DS reached ChatGPT performance "at a fraction of the cost"? If true, seems like it's more accurate to say that they were able to copy an expensive model, at low expense.

On the other than "less than 5 seconds of downtime" might give the impression that new queries sent within that time period would be rejected, while zero implies this doesn't happen, i.e. that it's undistinguishable from normal operation for the client.

And being even more precise in the title would just make it less titley :).
Yeah, I understand why that would be a concern. For what it's worth, our schemas are completely isolated and never touch any other data. We use them to store our DB functions and custom data types.

The functions are what lets us reflect the latest DB state in the UI in real-time without worrying about schema migrations or adding a bunch of reflection queries to each API call (which would make the UI much less responsive). We just need them installed _somewhere_ in the database.

Our custom data types (e.g. email, URL) are just available for convenience. If you don't have any columns that use those types, then you'll never need to deal with them.
For those who want to experiment with different click speed values without clicking, web console code that clicks twice with a set timeout:

setTimeout(() => document.getElementsByTagName('button')[0].click(), 1000); setTimeout(() => document.getElementsByTagName('button')[0].click(), 1200);

For those who want to test the limits of your device and your neighbors (100 clicks at once, 1s from now):

for (var i = 0; i < 100; i++) { setTimeout(() => document.getElementsByTagName('button')[0].click(), 1000);}

The self driving bit has to be nailed down first I think, once that's done nothing I've described is even remotely difficult to implement, it's more a matter of peoples thinking around driving evolving.

I think it might go this way because people feel like they want to "own" their "cars". Especially in America it's a big part of the culture, so I can see being able to buy the coach part as being a popular compromise.

Powering electric cars is already cheaper, but right now they're less convenient, with self driving they become as convenient or more than gas vehicles. You no longer have to stop and charge anywhere because there's a fresh "horse" waiting to be hooked up while your existing one drives off to a charging station, all the downsides are automated away.
You "can" forget to check an error, but in practice I've never seen it happen. The error check always happens after it is assigned so a missing check stands out like a clown at a funeral, and as a bonus there are linters that check for missed errors, which is trivial due to how Go and Go errors work.
The lifetime risk of clinical depression is someething like 30% for men and 40% for women in the west.

Recurrence is about 50% for people with one major depressive disorder occurence, and 80% for people with 2.

That makes it more akin to something like cancer in western countries with regards to lifetime prevalence (but not recurrence)
I agree to your comment, but also there's probably an unspoken gentleman's agreement that DeepSeek fixed the issue and won't pursue legal action against Wiz, since they were helpful and didn't do anything malicious.

I did the same a while ago, an education platform startup had their web server misconfigured, I could clone their repo locally because .git was accessible. I immediately sent them an email from a throwaway account in case they wanted to get me in trouble and informed them about the configuration issues. They thanked me for the warning and suggestions, and even said they could get me a job at their company.

I agree in a way, but then in that case Gemini Claude and Qwen are all derivations of each other and shouldn't be in the competition either.

DeepSeek did some studies on distillation, which might be what OpenAI is complaining about. But their bigger model is not a distilled version of OpenAI's.
Now you've opened the "comparison to previous technologies" can, not me.

For chemical and nuclear weapons, it makes more sense that they are restricted, because they are explicitly weapons. They have no benefit. The technology that underpins nuclear weapons does have benefit, and there are many nuclear reactors in the world. I don't know very much about chemical weapons, but I am guessing that the same chemistry discoveries that enabled chemical weapons has also gone into making useful chemicals or medicine.

For CFCs, we realized the negative impacts, and successfully internationally coordinated to stop using them. This happened after it became clear that the real harms that were actively occurring were not worth the benefits.
Stack traces are expensive. You need to make a conscious decision whether you want a stack trace attached to a particular error (and possibly where it gets attached, if you want it higher in the call chain), which aligns with Go's design philosophy for error handling.

I think an AutoHotKey script could do that (if it runs on Windows 11. I couldn’t easily find that on its site). Approach would be:

- in a “caps lock key pressed” handler, set a timer (https://www.autohotkey.com/docs/v2/lib/SetTimer.htm) that runs every ten seconds

- in that timer, check the value of A_TimeIdleKeyboard (https://www.autohotkey.com/docs/v2/Variables.htm#TimeIdleKey...)

- if it’s too large, call SetCapsLockState (https://www.autohotkey.com/docs/v2/lib/SetNumScrollCapsLockS...) and stop the timer

- otherwise, compute a new ideal delay from the desired run interval and A_TimeIdleKeyboard, and update the time interval

You also wail want to prevent starting multiple timers if you enable caps lock multiple times.

Well, I have been there in the past. Now though, I still get addicted to coding in such a way that, I was just thinking this the other day, I get a feel good reward from my brain if I code something well and it works. I am guessing this is a dopamine release? It certainly feels like an addiction.
Best Startup Perks You've Claimed?
I am curious to know what startup programs you're benefiting from.

I’ve personally claimed credits and perks from Azure, OpenAI, AWS Activate, Supabase and Notion.

Recently, I came across the Notion for Startups program, which offers a $100 Visa gift card and three months of the Notion Plus Plan.

Are there any other good startup programs offering useful benefits? Would love to hear what has worked for you!
Just do Andrew NG's course.

It will show you the maths, you'll build simple neural nets (from maths!) that can read digits and scale it from there.

While doing it, you may struggle with some of the maths, just take a deep breath and invest sometime to fill the gaps you need and continue.

> Other than increased miniaturization, the most striking change is the use of copper pours [...] Why did we start doing this?

We've been doing something a lot like this for as long as I can remember.

Back in the 1990s if there were any big unused copper areas on your PCB you'd mask them to save on etching acid - a gallon of acid would have a lifetime measured in square inches of copper removed, and the less copper you removed, the longer your acid would last.

Meanwhile, a lot of DIY etching processes were very basic. Sure, you could get translucent acid and a transparent bath and heat it to a controlled temperature and run bubbles through it and so on. But if you were on a budget, some room temperature ferric chloride in an old ice cream container would get the job done. And getting the etch resist onto the board? You could draw it by hand with special pens, use transfers, there were special printer toner transfer papers, or you could DIY UV photoresist using printable projector transparencies and the sun as your UV source.

This was not a super-scientific, tightly controlled process.

If you had narrow traces and narrow gaps on one part of your PCB, and large areas of copper to remove on another? Well, if you left it in the acid long enough to remove that large area, could be the narrow traces get etched away too.

So masking off any large areas meant all the copper getting etched was about the same width - thus compensating for the poorly controlled etching process.

Of course, these days professional PCB manufacturing is orders of magnitude cheaper than it used to be. When you send your design to pcbway or jlcpcb they have much tighter control over the process, so you no longer have to worry about this stuff.

It's not many out of 100 million. 4% would not be many out of the total. That's why I said: I thought you meant "a significant fraction of", not "at least a tiny fraction of".

You meant "at least a tiny fraction of". That's all. When you say "many", we should read "at least a tiny fraction of".

Thank you! And yeah, I understand your gripe. The tagline is meant to convey the general idea of "editing data in a table UI without a lot of clicks or keystrokes" in the fewest number in words; it does sacrifice precision (although that's why it's "spreadsheet-like" and not just "spreadsheet"). Do you have any ideas for language we could use instead?
> One of the big problems of the past was the insane level of trust in institutions that were at best credulous and more realistically just lying continuously and brazenly.

> It’s the opposite. Trust nothing, and we end up with pure chaos and the tragedy of the commons.

The parent comment you are responding to is appropriately qualified, and you are throwing away that qualification. Trusting institutions that taking advantage of you to look out for your interests is worse than not trusting institutions at all (example: the institution of slavery, justified by racist pseudoscience, when you are not a protected class). Yes, the existence of institutions that can be trusted to look out for your interests (example: food safety regulators wrt. hygiene) is important, if that is what you are trying to say.
To me the big question (which HN can't be bothered to discuss because SaM aLtMaN iS bAd) is whether DS shows that OpenAI can be done cheaply, or just copied cheaply. Your last sentence tells me you think DS built this from scratch. I haven't seen evidence of that.
Looking closer, there was a major increase quite recently before this decrease. On January 8th there were 3617 DoE datasets. On the 14th it was up to 5473. Now we're back down to just 30 more than on the 8th.

Could it have been a publishing mistake, or some order to undo recent publications for review by the new admin?
This would probably work for us but being able to

* do unit conversions by a multiplier - showing converted values in ui and converting on read and store

* hiding some (empty and irrelevant for specific situation) fields conditionally on values of other fields

would make this a much better fit.

I'm not an expert in Clojure or Rust, but an interested outsider in both, so please don't take my question as a challenge but a genuine curiosity:

Doesn't the focus on immutable data make most of the ownership stuff redundant? My understanding was that ownership lets you be sure that you're the only mutable owner of a resource, or otherwise that you share the resource immutably. If data is (almost) always immutable, which seems to be a founding principle of Clojure, then what does ownership/borrowing buy you?
Open Problems in Machine Unlearning for AI Safety
The modding scene still seems pretty healthy to me? R2modman's plethora of mods and games as one example. People seem to be very willing to make ways to mod games that don't come with official support, at least from some of my more recent modding experiences. It doesn't seem like the knowledge gets socialized as much as it used to though, or it's hidden from the public web more than it was (e.g. it's in Discord groups and DMs). Those who might tinker with files still seem to get by by installing other people's mods and then messing and remixing those which is kind of cool. But for most games it's _all_ community driven.

It's still rare to get modding tools from the developer though. Only a couple recent games I've played do that I've seen. Like Teardown for example
If I am not mistaken, this is done by modulation in Fourier space. We have already been using this in optical setups for ages - at the speed of light.

> and doing it anyway, and then lying about

To my understanding, this is not true. The "Sky" voice was based on a real voice actor they had hired months before contacting Johansson, with the casting call not mentioning anything about sounding like Johansson. [0]

I think it's plausible that they noticed some similarity and that's what prompted them to later reach out to see if they could get Johansson herself, but it's not Johansson's voice and does not appear to be someone hired to sound like her.

I can't tell from the Internet Archive. The datasets that went away seem to have been added quite recently, between January 8th and 14th. There isn't a suitable capture between January 8th and 25th to see which tags or categories changed within the DoE datasets.

> whether Deepseek has achieved real autonomy or if it’s just a derivative work

This question is malformed, imo. Every lab is doing derivative work. OpenAI didn’t invent transformers, Google did. Google didn’t invent neural networks or back propagation.

If you mean whether OAI could have prevented DS from succeeding by cutting off their API access, probably not. Maybe they used OAI for supervised fine tuning in certain domains, like creative writing, which are difficult to formally verify (although they claim to have used one of their own models). Or perhaps during human preference tuning at the end. But either way, there are many roads to Rome, and OAI wasn’t the only game in town.

Always happy to see clojure on the front page, doubly happy to see jank! I just scoured the internet last week trying to find all the information I could on it.

As a clojure(script) developer of 10 years, I still try and avoid anything JVM related. Not that I have anything against the JVM — but I never did any Java programming, and to really learn about the JVM you have to learn quite a bit about Java… which is just very low on my priority list.

I have been dreaming about jank a little bit, so maybe this is a good place to ask the question, since I see the jank developer is reading the comments: would it be possible to write a module in jank that can be used in a Swift/iOS application (currently or in the future)? I assume so, but I’m not sure how accessible the outputs of jank are to other c libraries.

The reason I ask is I have an offline clojurescript front end. If I want native mobile apps, that means I either have to duplicate the logic, figure out some JavaScript bridge, use react native, or use dart — none of which seem ideal. Ideally I could just extract the critical business logic into a few modules and generate the header files for swift, import directly into cljs for web, and use as regular clojure for android.

Totally understandable if this isn’t a valid use case for jank, but it’s what’s captured my imagination :)
