koolba··on Speeding up code review with `small-change`
It can be even more lines as long as the hunks are continuous. Once you lose the context of change and have to “zoom out” to see where it fits in, the review time grows significantly.
koolba··on Startup taps underwater volcano as energy source in “proof point” test
You might be interested in this section:

> Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative.

Seriously. How often do we get a story that intersects power generation and volcanos?

I read, or at least lightly skim through, the article I post about. But always post whatever comes to mind, regardless of how it will come across.

koolba··on Startup taps underwater volcano as energy source in “proof point” test
I’ve been expecting Oracle to do this. It’d solve their current data center power problem. And it gives a place for Ellison to have video calls with the UN.
koolba··on Nvidia announces plug and play Vera Rubin racks that can be shipped on a truck
> Nvidia announced Wednesday a new product that will put seven of its Vera Rubin AI racks into a shipping container, the company’s latest effort to move up the stack and offer complete systems for artificial intelligence computing.

> Nvidia did not announce a price for the system, but analysts say a single Vera Rubin rack can cost more than $7 million.

So around $50 million in one shipping container. I bet they put more than an air tag to track those on the move.

koolba··on The 1.5°C goal of the Paris Agreement is no longer viable
There’s plenty of delicious vegetarian dishes. I’m not a fan of the ones that try to be meat dishes replaced with vegetables or anything processed to pretend to be meat.

Vegetables are delicious on their own. There’s thousands of years of cultures around the world making vegetables taste wonderful.

koolba··on Eight Bits of Trust; eMudhra's CA keys cracked in milliseconds
What the chances there’s another CA key out there with something like unix time as the key?

Have you ever enjoyed a reverse seared marbled ribeye?
koolba··on Zuckerberg's Meta Takes Down No Kings Instagram During Protest Day
Run the full range. From, “Will no one rid me of this turbulent priest?” all the way to “10K to whoever takes out heimdall”.
koolba··on Zuckerberg's Meta Takes Down No Kings Instagram During Protest Day
> I don't view words as violent action, people can say whatever they want.

Where does that put someone calling out a public hit? It is just words after all.

> I could care less if someone wants to say they're going to hurt me. My beef is when they actually try to do it.

They say there’s no atheists in foxholes.

koolba··on Zuckerberg's Meta Takes Down No Kings Instagram During Protest Day
> According to the organizers, Meta failed to respond to their team for approximately 90 minutes while the account was offline during the peak of their national day of action and livestream.

Is it really that unusual to contact a large tech company and not get a response for (egad!) 90 minutes?

koolba··on Tsc-ts: TypeScript written in TypeScript
> An experimental TypeScript port of the TypeScript 7.0.2 compiler (TypeScript-Go, or tsgo), compiled to native code with scriptc.

I don’t get it. Isn’t the golang version already native?

Or is this one of those things where it’s not supposed to make sense?

koolba··on 90% of US working hours are spent on tasks not covered well by AI benchmarks
> …and the pump jockey hates your guts because he had to leave his heated hut where the Bruins were on…

Why would he be watching the Bruins and not the Devils?

koolba··on How the Claude Code team does code review
> Low - Docs, copy, internal-only features, additive changes behind a flag

> None required once automated review and security checks are green

How anybody can let an LLM write docs and not even read them is pure insanity.

koolba··on Do dentists know what they're doing?
> I went to a dentist in one of the new dental clinic "chains" that recently opened at my place, regarding some pain in the jaw, and they suggested to pull out a molar, and if the pain does not disappear, then suggested to take an X-ray.

The dentist suggested pulling out the tooth first and then doing an x-ray?

koolba··on CPI-U rises 7.2% annualized in September (3.7% YoY)
> Convenient how it doesn't also include housing cost increases …

It does, but only urban renting. It doesn’t measure increases in housing costs for suburbs directly. In particular it does not track increases in home values or mortgage payments for new buyers based on current rates.

koolba··on CFTC Staff Were Told to Retract Analysis of Suspicious Oil Trades
If she knew she wasn’t an actually a citizen yet still voted that’s a crime. If she lied about her birthday on federal forms that’s a crime too.
koolba··on Thunderbird for iOS
Vertical tabs are only better because there is more horizontally space on a as screen and listing things vertical allows you to both gauge the list size and keep a mental reference of what slot a tab was. And those tab headers don’t move because of resizing when the width fills up.

But horizontal tabs are still better. Not technically better or ascetically better. Some other immeasurable, indescribable better.

koolba··on Firefox Enterprise
Hell yah. This is exactly the type of thing they need to do to take their mouths off the teats of advertising companies like Google.

Make privacy at the enterprise level the first class feature.

Too bad people won’t pay for any of this.

koolba··on An hour of audio transcribed in about 13s on MacBook Air
Too bad the errors for things like this are not truly independent.

Otherwise could run two passes to get down to .25% or three passes to .0125%. Or four passes to .000625%!

That’d be .02 seconds of error per hour!

koolba··on The Case for Firing Squads
> Let us amplify the words of that young girl--"It is wrong to kill, even in war!" And let us broadcast them to the world!

Indeed. But until that time, if we are going to do it, better it be done in a way that will clearly succeed.

Unless you’re this guy: https://en.wikipedia.org/wiki/Wenceslao_Moguel

koolba··on The tilde in your PATH may not be your HOME
> Also, not exactly a page turner.

Really? I can’t be the only one that will spend hours reading this kind of stuff. You guys don’t read man pages for fun?

koolba··on I would like the value of my home to rise, while my property taxes fall
The problem with having the city pick things like your trash pickup is that you end up bound to whatever choices they make.

In Canada for instance, I’ve seen towns where they have pick up once every two weeks and the canister is not even a full size one. It’s a “gentle” push to get people to recycle and compost.

No way that would fly in Freedom Town USA.

koolba··on Calling It Quits on ServerFault
If the AI’s are the one exchanging the ideas then it should be AIsexchange.
koolba··on Anthropic reported diary entry to police, woman faces felony charge
> Today I learned about "foldering"[1], which uses the drafts folder of email systems as a "dead drop" between multiple participants. It goes back to at least 2005.

Former head of the CIA, David Petreaus, was using the drafts folder of a shared Gmail account to communicate with his mistress.

koolba··on Agents don't need memory, they need documentation
Except you can’t do that unless the runtime itself can reason about what’s being executed.

Otherwise you can get a python one liner that execs a different script engine.

koolba··on So you think you could be an electrician?
> Yes, I know, gloves, rubber soled shoes, he was fine, but it still was somewhat terrifying to watch.

What gloves? For 110V? Bah!

Unless you’re a complete idiot and try to cut both wires at once with a conductive cutter, nothing happens when you snip them one by one.

And selection bias means we don’t see those guys around for long.

koolba··on We're going to need default hard budget caps on pretty much everything
It’s not a binary decision though. Any sensible enterprise has many AWS accounts. Often hundreds or thousands. It’s the only clear separation of privilege.

There’s no reason for the majority of them to have an infinite budget cap. Prod? Sure. UAT? Why not. The sandbox environment Johnny just spun up to test some new agentic workflow? Hell no.

koolba··on Federal judge calls Flock 'indiscriminate mass surveillance'
> Can you do that remotely at speed?

Even if you can’t, if you put enough of them by stop signs and traffic lights it’s a non-issue.

koolba··on Mike Tomlin spent 12 years building a Minecraft city
I laughed when I saw the naming thinking, “hey this is the same as the Steelers coach”. Crazy that it actually is him, but hey he’s human too.

Interesting choice for his favorite rooftop 12m in!

koolba··on ICC judge on what U.S. sanctions mean for her and global courts
> Regardless of what one personally thinks about the ICC, this isn’t a good look for neither the US nor Europe.

> For the U.S., because sanctioning an “unpleasant”, but in essence harmless individual (geopolitically speaking) is ridiculous. Falling victim to de-banking alone can really ruin one’s life.

Not a good look sure, but I wouldn’t be surprised if it’s effective over the near term. Especially if they keep expanding this to include more of the ICC bench.

That’s the whole point of such sanctions anyway. It might feel different because it’s a Canadian judge and not a Russian oligarch. But at the core the USA wants to put pressure on something and the means is indirectly applied to an individual.
