a-priori··on Microsoft patches Windows and Excel – breaks audio, remote access, and paste
All I’m saying is that if your idea of driving a car is to sit on the engine compartment and pull levers and cables from there, you might have a different experience than most drivers.

If you're talking about compiling WiFi drivers, then you're not using Linux the way most people do.
a-priori··on Field measurements of neighborhood-scale air temperature impacts of data centers
As measured by power consumption, the scale of data centres is a lot bigger now than they used to be. A typical large data centre is on the order of several hundred megawatts sustained consumption, up to a gigawatt on the high end for planned facilities. The economic pressures are entirely in favour of building larger because of latency and also permitting (one large facility is still just one facility to get through zoning), so we should expect the size to only be constrained by external factors like availability of land, energy and water.

This energy is all turned into heat, which means a 1GW data centre facility will dump 1GW of heat energy into the environment, into some combination of air, water and ground. For comparison, the average energy use for the whole city of Toronto, Canada, is 2.7GW, so just three large data centres has roughly the same heating impact as all the air conditioners, baseboard heaters, toasters and ovens of a large city.

That's a lot of energy to dissipate in a small area, so it should absolutely not be surprising that it'll create a local heat island downwind or downstream in the same way cities do.

a-priori··on Moonshot’s Kimi uses 20k Nvidia chip cluster from Alibaba
It kind of confirms a hypothesis I have that the next phase of AI development will be about getting smaller (in terms of model size and compute), because smaller is more capital efficient for training (allowing faster iteration and more iteration cycles for a given amount of capital), allows for denser inference (more inference for a given amount of compute hardware), and allows for more edge inference applications.

The goal will be to develop smaller models with more efficient architectures, that have similar or even better performance than larger models.

a-priori··on Apple Private Cloud Compute SoC 3 audit reports
A SOC2's quality entirely depends on how much you trust the auditing firm.

Delve used an audit mill they paid to rubber-stamp the cookie-cutter and AI slop reports it authored. I hope it ends up in fraud charges.

But I wouldn't assume that's the case for all SOC2 reports. Any decent auditing firm should be far more rigorous.

a-priori··on Antimatter has been transported for the first time
It would develop into "regions" of space that are entirely matter and others that are entirely antimatter. The boundaries between them would glow as stray particles drift between the regions and are annihilated by contact with the opposing particles.

The fact that we don't see these glowing boundaries in space is evidence that there are not antimatter regions and that the visible universe is almost entirely composed of matter.

a-priori··on SQLite JSON at full index speed using generated columns
Yes, as far as indices go, GIN indices are very expensive especially on modification. They're worthwhile in cases where you want to do arbitrary querying on JSON data, but you definitely don't want to overuse them.

If you can get away with a regular index on either a generated column or an expression, then you absolutely should.

a-priori··on Genergo: Propellantless space-propulsion system
Yes but they also don't seem to claim it does. The use cases they talk about are orbital station-keeping and de-orbiting of satellites. So that implies near-Earth use.
a-priori··on Genergo: Propellantless space-propulsion system
They say it works "by directly converting electrical energy into thrust through controlled electromagnetic impulses", so I assume it's reacting against the Earth's magnetic field using the Lorentz force?
a-priori··on Steam Censorship of Adult Games Shows How Payment Processors Wield Immense Power
This is generally true not just for Steam. By issuing a chargeback, you're burning that bridge and shouldn't be expect to do business with that vendor again.
a-priori··on Async Queue – One of my favorite programming interview questions
You'll need to flatten the promise periodically if you use this approach, otherwise your performance will degrade a bit each time you enqueue something.
a-priori··on Alberta separatism push roils Canada
My point is that legally the First Nations have the right to not consent to the separation of provinces from the country. Of course, it's always possible for parties to act illegally...

If Alberta did unilaterally declare independence (which would be illegal according to Reference Re Secession of Quebec [1998]), the First Nations have the right to call upon Canada to defend their treaty rights under the "peace and good order" terms of the treaties.

If Canada did grant Alberta independence without First Nations consent, or Canada refuses to defend their treaty rights, they would have a claim that Canada had violated their rights to self-determination under the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) which Canada ratified in 2021. But UNDRIP is a non-binding resolution, so I don't think they'd have a case with the ICC or ICJ (even assuming it had jurisdiction).

a-priori··on Alberta separatism push roils Canada
Alberta would need the consent of the councils for Treaty 4, 6, 7 and 8 in order to take their land with them. The treaties are between various First Nations and the Crown of Canada and are not transferable to an independent Alberta without consent.

Some provinces have non-treaty land, acquired through land purchases or conquest. Quebec, for example, had the right to take roughly the southern third of its territory when it discussed separatism. But that's not the case with Alberta — it is entirely composed of treaty land.

This means that Canada cannot grant them independence, even if it were to accept the results of a referendum that meets Clarity Act requirements. That alone makes Alberta separatism a non-starter. There's no legal route for Alberta to separate from Canada without negotiating new treaties with the treaty councils in order to get their consent, and they've already signalled they are not willing to do so.

a-priori··on RubyUI (Former PhlexUI): Ruby Gem for RubyUI Components
It's basically a code generator for adding standard Phlex components to your project, so once you've added a component to your application you can modify it any way you want.
a-priori··on Canada considering charging for road access from USA to Alaska
Ugh, yes you're right, I typed too fast and mixed things up. Thanks for the corrections.
a-priori··on Canada considering charging for road access from USA to Alaska
Of course, NATO was founded on the assumption that the US is a reliable trading and security partner, and the defense supply chains reflect that assumption. It will take time to untangle those chains, but you're watching all of NATO speed-running that process right now.
a-priori··on Canada considering charging for road access from USA to Alaska
We had free trade. The US has, in a very short period of time, squandered what was a highly profitable and mutually beneficial trading relationship.

There was already a sentiment of distrust in Canada about being so dependent on American goodwill. You can see this in the debates from the 1998 federal election (https://www.youtube.com/watch?v=gyYjRmM7RDY) on the establishment of CUSFTA, the precursor to NAFTA and later CUSMA. Brian Turner (red tie in that video) argued that free trade in Canada would lead inevitably 'reduce' Canada to becoming a 'colony' of the United States. He lost the election, and the agreement went through. Here we are almost three decades later and, as Canadians see it, those fears are at risk of coming true.

I'm not sure that Americans really understand that this has permanently damaged the relationship between our countries. It's going to be a generation before there will be the political will in Canada to consider going back to something similar to NAFTA/CUSMA again. Even assuming the United States returns to open trade policies again, the question forever on everyone's mind will be "what if another Trump gets elected?".

a-priori··on Canada considering charging for road access from USA to Alaska
Absolutely. Canada is almost certainly going to cancel or severely limit a pending F35 order, and is actively sourcing aircraft and negotiating mutual arms deals with European partners.
a-priori··on Canada considering charging for road access from USA to Alaska
It's incorrect to think of Canada as being "cornered" here nor having "nothing to lose".

It's the US that's isolating itself. Canada isn't 'cornered'. It has the entire rest of the world to talk to and make deals with.

It has everything to lose by continuing to rely on the US, which is why you're seeing such a hard pivot toward Europe and Asia.

a-priori··on Cot: The Rust web framework for lazy developers
Honestly as someone who has been building Rails applications for over 15 years now, I find far too many people think they are special and need to stray from the defaults.
a-priori··on The Profitable Startup
You could dismiss almost any company as "if all you're doing is building an X app...". It's a no-true-Scotsman argument.

Even setting that aside, not everything is or should be a land grab. It's notable that all the examples you provided — Amazon (at least, its initial online store product), Uber, Facebook — are all B2C plays and I don't think that's a coincidence.

a-priori··on Carbon capture more costly than switching to renewables, researchers find
When trees die, they’re consumed by fungi, and the carbon is sequestered in humus (soil). That’s totally fine, and in fact is an important reason to ensure that planted forests have a fungal culture so this decomposition process occurs properly.

You’re right about fire releasing carbon. But even after devastating fires, forests don’t burn completely and plenty of plant matter remains. Even ash and soot is still sequestered carbon, not to mention charred wood even if the tree doesn’t survive.

a-priori··on Good engineers are right, a lot
The way it was explained to me when I was at Amazon is that the intent of that principle is that good leaders should “make themselves correct” by gathering the data they need to have well informed judgement.

So in retrospect they’re “right a lot” because they actively seek to align themselves with reality and therefore are better able to predict the outcomes of their work.

a-priori··on Advice for a friend who wants to start a blog
It’s not. It’s a recognition that you have to act within the world as it exists today.

That doesn’t mean you can’t work to change the world, and in fact in order to do so you first need to see how it actually is.

But it does also means you need to decide which battles to fight.

a-priori··on Advice for a friend who wants to start a blog
You can’t worry about it. It’s the world we live in now. The alternative is to not write anything of significance on the internet, which would be of no benefit to anyone.
a-priori··on Ask HN: Would you still choose Ruby on Rails for a startup in 2025?
The good news is that I can just say: go ahead and Google “DHH blog”, read his most recent few blog posts and form your own opinions.

I’ve had a negative opinion of him for a good five years or so, but at least right now it’s easy to go read those and form your own strong opinion one way or another.

a-priori··on Ask HN: Would you still choose Ruby on Rails for a startup in 2025?
I’ve built my career on Rails. I first got paid to write Rails code in 2008, then came back to it in 2015 and have worked in it almost nonstop since then.

It’s a wonderful technology, and it’s still as fresh and relevant as it was when I started. I plan on continuing to use it for the next decade.

My only recommendation is to never listen to a word that DHH says. If you don’t know who I mean by “DHH”, that’s all the better.

a-priori··on Ask HN: Would you still choose Ruby on Rails for a startup in 2025?
The worst part about Rails is the 37signals people, in particular DHH.

But the good news is that you can just ignore them and enjoy the framework, like I do.

a-priori··on TikTok goes dark in the US
I mean, we could be getting closer to that point. According to a recent survey, 26% of Canadians now consider the US to be a “threat” to Canada and 6% consider the US to be an “enemy”. Those numbers is up from 6% and 1% two years ago.

a-priori··on Justin Trudeau promises to resign as PM
Thanks for the list! I can say that three of the stories I was referring to above are the ones listed as "Attacking a shop employee for masking up on their way to work", "Smashing windows of a business with a Pride flag" and "Trying to handcuff shut the doors of an apartment building".

The first and second happened only a couple blocks away from us, and we frequented both businesses, so it was infuriating to see them and their employers attacked like that. We lived in an apartment building so the third one was pretty alarming.
