coliveira··on CEO fired developers to make room for AI. Developers create open source AI CEO
That's funny when you said that a CEO reads the body language of programmers. CEOs and high executives don't even bother looking at you!
coliveira··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
> China that still seems acceptable

China has made a tremendous effort to move to a clean(er) industrial system, using a lot of renewables and clean energy and improving environmental standards. At this point production in China is probably the best for the environment compared to most countries, including the US that is deeply invested in oil production.

coliveira··on Canada will match US tariffs 'dollar for dollar' as trade talks break down
Here's the problem: as bad as republicans are, democrat governments have the tendency to let most everything they did in place, and even add more as a way of playing a "bipartisan" game. The result is that democrat governments don't change the economy in any substantive way that can give a reason for people to support them.
coliveira··on US Debt-to-GDP Ratio
High inflation will fix this: it balloons the USD denominated GDP, so very soon this will be less than 100%. At the same time, the US will export inflation to other countries, since products are denominated in inflated dollars, and pressure them to live with high inflation as well, ultimately forcing the value of other currencies down with respect to the dollar.
coliveira··on CIA funding helped keep NeXT afloat in the 80s
You're just confirming it.
coliveira··on CIA funding helped keep NeXT afloat in the 80s
The garage or dorm story is the biggest myth they keep repeating, it's basically nonsense.
coliveira··on CIA funding helped keep NeXT afloat in the 80s
The art may have been created independently, but rich money laundering is the main reason why that art is considered valuable. Remember that this is a movement created in NYC, where they perfected the connection between strange new art forms and billionaire collections of paintings valued into the several million dollars.
coliveira··on Linux 7.3 improves performance when running out of vRAM
This is the best explanation, thanks.
coliveira··on Tail-call optimization in C is relatively recent (2025)
For people who passed their 30s, everything that happened after their 20th birthday is recent. For me, September 11 is recent memory, as well as the 2008 great recession.
coliveira··on My server is a phone now
This type of problem doesn't happen in all languages. Many languages are more precise than english and will avoid exactly this type of ambiguity.
coliveira··on Why Wall Street is ignoring big tech's debt [video]
Most people don't understand how cheap models like DeepSeek and similar are. I have $5 in an account that I use for months. I can get very complex code for less than 50 cents.
coliveira··on My server is a phone now
This shows a problem with the English language: the same sentence can be understood in at least two ways: "the server can now work as a phone", or "the phone is now my server". It is to solve this kind of issue that many languages have markers to specify what each noun means in the sentence.
coliveira··on U.S. Department of Energy Launches the Genesis Open Models Initiative
You're kidding yourself if you don't realize that the US gov can have access to any data they want in any of these US-based products. That's why they consider so important to "win" the development race for LLMs. It is a matter of continuing to access and control data that most of the world needs, as China has already closed the door to them.
coliveira··on Oracle bans AI-generated code from OpenJDK
A lawnmower doesn't decide to do something bad by itself. The case with L.E. is much more sinister.
coliveira··on AI's debt binge can't last, hidden borrowing reaches $1.65T
> incredibly sophisticated companies

We need to stop thinking that just because they have money they're incredibly sophisticated. We have a few examples like Mark Zuckerberg, who had early success with FB, but he seems to be incapable of investing in profitable products. E. Musk: great at selling his companies, but laughably bad at making profits at the same level of expenses. Sam Altman: never had a real job he did well other than raising money. This is the kind of people that control these companies.

coliveira··on How Hollywood stopped making movies in Hollywood
Also, a lot of real estate is owned by the Hollywood investors or their close friends, so this is a circular economy where they get rich, then buy property in that place and get even richer with real estate increasing in value. The same thing happened in Silicon Valley, Wall Street, and many other places.
coliveira··on How Hollywood stopped making movies in Hollywood
What will probably happen is that they'll buy the rights to use faces of famous people (actors or not) and use AI (or cheap actors) to do the real scenes.
coliveira··on Europe EV Sales BEVs Jump 50% & Reach 26% Market Share
Yes, but Americans don't have the freedom to experience this. They have to choose between expensive and more expensive.
coliveira··on Europe EV Sales BEVs Jump 50% & Reach 26% Market Share
EVs continue to be expensive in the US. But the trajectory is the opposite in the rest of the world due to the benefit of Chinese exports. In Brazil, for example, new car prices have a now a discount of up to $10K, all due to increased competition from China.
coliveira··on How the words we teach English language learners changed
When you're a foreigner learning a language your experience is mostly from reading. There are words, however, that are much more common at home and in spoken language. So you'll probably never learn the words that a 10 year old kid knows.
coliveira··on Google fixed more Chrome bugs in June than over the past two years, thanks to AI
Yes, it is relatively easy to find any solution to a bug. It is hard to find the root cause and change only what is necessary to fix the bug. AI makes it very efficient to "fix" bugs with code that needs to be fixed again later. The big problem in fixing bugs is understanding what is causing it, not to suggest a temporary "bug fix".
coliveira··on Google fixed more Chrome bugs in June than over the past two years, thanks to AI
Bingo. The issue is not lack of knowledge but prioritization at these companies. Microsoft has the ability to fix Windows bugs, they just think it's secondary compared to adding their own new bug ridden features.
coliveira··on Patreon laying off 20% of staff
Panic may only exist in a company that is already lying about its true situation. If managers were telling the truth about what is going on in a company, everyone would be Ok with new updates about its financial position.
coliveira··on Patreon laying off 20% of staff
A society that doesn't value honesty deserves to be deceived.
coliveira··on Patreon laying off 20% of staff
Business schools teach advertising, not business management. In modern business it is a crime to tell the truth about the dire situation a business is in, unless a CEO is starting anew to fix a situation left by another, and even then it rarely happens.
coliveira··on Startup founders urge U.S. government not to shut off Chinese open weight AI
That's nonsense, people pretend that a "frontier model" is the most important technology ever, but we know for sure it cannot be because several companies are doing copycats of one another. It is not China that is doing much effort to copy-cat, it's the US companies that are copying one another. The only real barrier in this technology is how many Nvidia chips you can buy and how much data you can get to train your LLM. All these models are basically moving in the same trajectory, it is essentially a very expensive copy-paste job they're doing.
coliveira··on China’s open-weights AI strategy is winning
Chinese companies are cut out of the market by the US gov restrictions, so making the models open is a survival tactic.
coliveira··on A road to Lisp: Why Lisp
The issue is also social, the average software engineer will treat Lisp code as a liability because most people really don't know what to do with it. In the mind of a professional SE, code is "maintainable" only if it's writing in Javascript or some other commercial language.
coliveira··on Falling fertility on the left as key driver of US birth decline
That's an incredibly short sighted way of looking at countries. The US was never the country with highest population growth, and right now is also heading into a demographic collapse.
coliveira··on Falling fertility on the left as key driver of US birth decline
A group having more power has little to do with numbers. If that was the case the rich would be more numerous than the poor, and India would be the most powerful country in the world.
