marcosdumay··on OpenAI bots knew about the RubyGems caching vulnerability
What kind of esthetic alteration would make you more comfortable clicking on that link?
marcosdumay··on How to write an effective software design document
In every single one of those, you are more concerned with the validation data than with high-level visions of your software.

Documentation is important for platform, and probably nothing else.

marcosdumay··on Flock cameras used to arrest a child for playing on a swing
Of a government body deciding to go around arresting people for no reason? Yes.
marcosdumay··on Flock cameras used to arrest a child for playing on a swing?
> If the town feels that arresting children is a good use of public money they that's their right.

TF? Doesn't your country have a Constitution?

marcosdumay··on AI recursive self-improvement might not come so quickly after all (August 2026)
Do you think the final product of research is papers?
marcosdumay··on Making Startups Powerful
> I do think that the startup pendulum swung too far in the direction of shipping as fast as possible.

Nope. They did, but that's not the problem.

The problem is that VCs moved way too much in the direction of "take over the world or go home" and don't allow companies that take investment to be just successful anymore.

marcosdumay··on Nvidia dismisses "circular financing", says every $1 it invests brings back $100
If I'm reading that correctly, then 59% of them claim to plan to use AI, 11% of them claim to use AI and 0 of the AI buyers (absolute number) claim that AI pays for its costs.

Is it really that? AI is still heavily subsidized.

marcosdumay··on Everyone should slow down AI development except for me
If an anti-cat-ears future AI could eternally stress-test their new version of the router in front of this site unless it collaborates, would it predict this outcome and act to avoid the damage?
marcosdumay··on A Design Space Exploration of Async/Await
No, they don't. With threads almost all of those properties are explicit choices that the developer has to implement.

At most you get hidden behavior on exception propagation and end-of-life extent.

marcosdumay··on A Design Space Exploration of Async/Await
The principal difference between threads and async/await has to be specified in at least 9 dimensions...
marcosdumay··on Silicon Valley is transforming the military-industrial complex? (2024)
The US is almost uniquely evil, though.

People should ask the same question in the likes of Russia, Israel, North Korea, Iran. But in most countries, defense actually means that.

marcosdumay··on Creativity is the New Moat
Yes. AI changed everything!

Just like they made it possible for people to program in more than one language like people were pointing on the React Native post earlier today. We totally couldn't do that before!

marcosdumay··on AI 2027 (2025)
Yes, there exist cloud computing companies that took a long time to be profitable. IDK if Oracle ever was.

Cloud computing was still profitable the entire time. Amazon alone could cover all of GCP expenses.

marcosdumay··on AI 2027 (2025)
No, it wasn't. Cloud computing was almost immediately profitable.

And Amazon was famously "unprofitable" for their first 9 years because they were investing all their very real profits into a form of capital that the US tax code didn't recognize.

marcosdumay··on List of references on Sony websites to players "owning" their digital games
Honestly, nowadays I'm tending towards the idea that huge TOS or EULAs (at all) should be criminalized.

It's ridiculous that rich people just get to use the justice system as a goon to harass normal people.

marcosdumay··on Python sets and dictionaries can have quadratic-time performance
Nowadays I expected an opaque dictionary to be amortized O(1).

Granted, one can technically call that O(log(n)), but that's not a helpful categorization.

marcosdumay··on More questions about whether researchers can trust OpenAI with unpublished math
It's not collecting other people's data and claiming it's your own.
marcosdumay··on Navier-Stokes – Tristan Buckmaster [pdf]
If you still had that question, you can answer it now.

But honestly... "Will the company that was entirely built over illegally acquiring data use some data that is legal to use and is right on their front, or will they not do everything they reserve the right to do?" is a really bad question for one to even ask.

marcosdumay··on Shopify acquires Tailwind
Vanilla CSS can take advantage of features like that "cascading" part that Tailwind goes entirely against.

If you are styling a site, there's no competition at all. But if you are styling a single interaction-heavy page, it's a lot less work to put all the formatting inline instead of thinking about a descriptive structure and write your CSS around it.

Apparently a lot of people design entire sites one page at a time.

marcosdumay··on 'Lake America' makes one thing clear: We can't trust U.S. tech companies
> At the end of the day a map provider has the responsibility to show the official names of places on a map.

Not really. They have the responsibility to show the useful names. They are also free to show whatever the local bully forces them to.

Neither of those is necessarily the official name.

marcosdumay··on There's a new "Google Jail" for independent wikis
> Have the internet cards been handed out now, and are we in the end-game?

The big companies are trying to corral and kill everybody else, yes.

That's not some "end-game", though. It's just powerful anti-social entities doing their thing while society refuses to punish them.

marcosdumay··on Bill Gates tries to install MovieMaker (2003)
Ironically, they could have learned from Jack Welsh to separate the product divisions and make redundant teams on each one to solve the ownership issues.

When people compete internally on Microsoft, what are they competing on if everybody works in a different horizontal?

marcosdumay··on Why the AfD Wins
That seems to not matter for the people that think the way the GP points.

(And they are quite distinguishable. The far right is way worse at it than the kind of left party that wins anything.)

marcosdumay··on Why are there no flow batteries with symmetric ferrocyanide electrolytes?
Putting stuff in electric fields while thinking "well, it's stable" is a fool's errand.

(As the article says...)

marcosdumay··on Nitter and XCancel resume service after legal advice
Yes, you can subscribe from whatever instance you want.

(I'm not a mastodon user either. But I've read the docs.)

marcosdumay··on Research acceleration: The view inside OpenAI
The name you are looking for is "fixed points", not "eingevalues".
marcosdumay··on Netherlands pulls gold out of the US
> No gold dealer will turn down investment grade gold.

For sure. As long as you pay the laboratory fee up front to prove that the thing you have is investment grade...

marcosdumay··on Nitter and XCancel resume service after legal advice
As long as the service provider runs an instance in their infrastructure and allows everybody to read.

That said, RSS seems way simpler.

marcosdumay··on Netherlands pulls gold out of the US
Yes. Gold is fungible only within the same custodian.

Many people buy (normally small) gold bars only to discover that they can't sell them back by the same price.

marcosdumay··on AI handles incidents, engineers lose touch with their systems
That happens all the damn time... Some otherwise competent developer decides to use AI, and falls into the pattern where AI will pretend to solve their problem for a week, while if they would have to think about it for an entire long hour to discover how to solve it by themselves.

As a bonus, that person will spend half of the week asking their peers for crazy delusional stuff.
