koolba··on The state of open source AI
I don’t think US companies could ever fully trust models sponsored by foreign adversaries. How would you ever verify they are safe?

Provenance of training set is going to be critical. It’s largely ignored now, but the first time a malicious exfiltration occurs it will go off as if a bomb was detonated.

koolba··on SPCX is now Wall Street's most shorted new stock
There’s always a buyer on the other side of a short, naked or located. The question is whether the originating broker actually borrowed the shares.

They are supposed to verify that before they place the trade and generally do follow the rules. Because if they don’t, they will be not allowed to allow any short sales for that security.

koolba··on Where are YC founders now? OpenAI and Anthropic, mostly
The site infers that 105 people are working at the two companies. What’s the denominator though?

After 20 or so years of YC, with multiple catches per year, and the insanely high failure rate of start ups, there must be a lot of former or floundering founders.

koolba··on Open-source memory for coding agents, synced over SSH
> My setup is a laptop and a mac mini without an interface. The agent can work on the mini all night, and in the morning I extract its memory. Then the agent on my laptop will know what the mini tried, what broke, and what eventually worked.

If it’s fully automated and then blindly injected into your laptop without any vetting, isn’t that a perfect vector to break that separation?

koolba··on SpaceX bond worth 10% less than issue price – heading for junk bond status
Even in the case of a default it’s not a zero payoff. Bond holders get first dibs of unsecured assets at liquidation.
koolba··on How to stop Claude from saying load-bearing
Which is a perfectly cromulent usage of the phrase.
koolba··on Cursor 0day: When Full Disclosure Becomes the Only Protection Left
Is it though? Cause you can have an agent analyze the reports to filter out the wheat from the chaff.
koolba··on Your 'app' could have been a webpage (so I fixed it for you)
I like apps to sequester authentication. Not for everything, but nice to keep some things only authenticated in their own walled garden.
koolba··on Why write code in 2026
Yes in three specific environments for varying durations. Lying down to sleep, showering and driving.

Each last for a different amount of time and you generally can’t write or even read anything. But in my personal experience, all three lead to solving the most difficult software problems.

koolba··on Female US rower completes historic solo journey from California to Hawaii
That’s incredible.

What does one eat and drink on a trip like this? The article talks about her cooking. With a fire or one of those little butane stoves?

Can a small canoe carry enough water for a trip like this or do you rely on rain water too?

koolba··on USAA closed 51% of home insurance claims without making a payment in 2025
> Last year, former USAA CEO Wayne Peacock received $14.1 million in total compensation from five USAA insurance companies for working slightly more than a quarter of 2025 before his retirement. That was a 47% increase from the $9.6 million he received in salaries and bonuses in 2024. Other executives at USAA also received pay boosts in 2025.

At about 1M policy holders that’s about $14 per policy. Not bad for a couple months work.

koolba··on Why We Don't Trust the Database with Authentication
You could (and should) run with minimal permissions which would exclude DDL.
koolba··on Show HN: Reviving my 2001 college band with AI
That video from 2004 is so refreshing. It’s just two people talking without asking me to “please subscribe” every 30-seconds.
koolba··on TypeScript 7
> In 2004 we solved the types for JS with ECMAScript 4 (or ActionScript 2.0).

> Unfortunately this was in the middle of browser wars, so no one cared about the standards and all of that work was lost like tears in rain.

> Around that time I attended MS conference where they introduced IntelliSense and it was a forming experience for myself. You could do actual programming basically with <space>, <dot>, arrow keys and <enter>.

I think you’re off by at least 6-7 years. Visual Studio had autocomplete since at least version 6. And yes it was magical the first time you experienced it.

koolba··on John Deere owners will get the right to repair equipment under FTC settlement
> Fines should really be about "what size fine will be a deterrent for this company?"

To a degree. But it also has to be commensurate to the actual market size and impact. If an Amazon releases a defective dog toy that is bought by 10 people, it’d be unreasonable to fine them $100 billion dollars just because they’re a huge company.

koolba··on Price per 1M tokens is meaningless
This reminds me of cpu benchmarks vs actually running games and measuring FPS.
koolba··on Memorizing session transcripts isn't useful
The two sides would be the strongly typed union and the duck typed heretics of the confederacy.
koolba··on AI can't be listed as inventor on patent applications, Japan's top court rules
Some will surely exist. We already have public funding for things that are not particularly profitable. The question is if it will net a better system overall.

Even with the current system everything older than X years is public. That means we should have better care options available then anything X years ago. And that keeps increasing.

koolba··on The primary purpose of code review is to find code that will be hard to maintain
> Our entire small team thumbs up a PR before it's merged unless there's a big rush on it, and this gives everyone on the team a rough idea of the state of the codebase at any given time.

For non trivial or chore updates a second pair of eyes is always a good idea. But it’s not possible to scale out “everybody reads everything” to a large N. The problem is that nobody could keep up with that ad the reader when there are some huge number of things to read. That’s why we delegate, create docs, and have overview sessions.

koolba··on Healthy but sedentary people show early decline in cellular energy production
> You'd need to find subjects that are provably capable of sustaining intense exercise as a habit if they wanted to but never did, and won't either for the years you'll be following them.

With modern 24/7 health tracking we’ll have tons of data in the next 50-100 years. Problem is we need that much time to see the net effect and will probably be too late for most of you reading this.

I wouldn’t wait for the results though. Best to start moving now assuming it’s probably good for you.

koolba··on Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5
When it was briefly available I had it fallback to Opus for security related tasks. It would only refuse if you explicitly told it not to fallback.
koolba··on 30-year sentence for transporting zines is a five-alarm fire for free speech
> Intent is an important aspect of crime.

Intent ia required aspect of most crimes.

When it’s missing, the charged crime usually includes recklessness.

koolba··on Professor denounces mass AI fraud on an exam at Brown
Classic story indeed. They gave a version of it in the movie Slackers: https://youtu.be/totdoS6px5k
koolba··on On cigarettes
Some of us are old enough to remember smoking sections on planes. (And yes it works out exactly as bad as you’d expect it … great way to past time on a transatlantic flight though!)
koolba··on Ford hired AI and sacked humans. It backfired badly
The other classic one is, “What’s Ford backwards? Driver Returns On Foot.”
koolba··on Ketogenic diets slow melanoma growth in vivo
Full title is, "Ketogenic diets slow melanoma growth in vivo regardless of tumor genetics and metabolic plasticity".

I always wonder if things like this are not pursued more often due to the lack of a market for fasting.

What do you sell to people when the cure is not to consume anything?

koolba··on OpenRA
I would pay inflation adjusted original retail for a GOG DRM-free version of RA2.
koolba··on Apple raises prices of MacBooks, iPads
Anytime inflation comes up and the relative power of computing devices is mentioned, I remember the classic[1] line that you can’t eat an iPad.

Computing is definitely cheaper, but crappy software seems to always seams to step up to the occasion and use up the extra cycles.

koolba··on Quebec town recognizes trees as living beings with rights
Most cities already have strict rules for removing existing trees. Usually anything over 6 inch diameter at shoulder level is off limits without getting specific approval.
koolba··on Crypto in 2026: Oh, This Is the Bad Place
Each $1 of stable coin is supposed to be backed by $1 of dollar or short term equivalent. So the issuer is making money by collecting interest on it.

3-4% of billions (USDC alone is $80 billion) would itself be billions of dollars of annual interest. Easily covering the operating cost of these companies.

However, they don’t keep it all. Nobody is going to let you hold their cash in size without getting a slice of the interest. All the big players (like an exchange holding USDC of its patrons) cut deals with the stable coin issuers for a revenue split of that interest.
