coliveira··on A Privacy Analysis of Web and Mobile Conversational AI Agents [pdf]
Yes, the media has conditioned most of us to believe that anyone starting or investing in a tech company and at least a billion dollars in equity is "doing good" and should be emulated.
coliveira··on Excel now supports multiple values in a single cell
The same thing that works for databases also works for excel. You shard the data and run your analysis on the set of shards in excel. It's not elegant, but can solve many problems.
coliveira··on Looking forward to Git 2.56 – and 3.0
Somehow we have binary file format parsers written in C everywhere, so the real world shows it is possible and we do have programmers capable of doing it.
coliveira··on Looking forward to Git 2.56 – and 3.0
If that's the case, they should stop using git and Linux right now, because it's everything written in C. Having 0.1% of the code in a safe language will not change anything, it's only a bad security blanket.
coliveira··on Looking forward to Git 2.56 – and 3.0
It is regrettable that they're trying to coerce the use of Rust everywhere just for the sake of it. It's a nonsense that is now forced on everyone.
coliveira··on ChatGPT now knows what you do on other websites via ad collector
Governments will also pay for the tracking capabilities, as they're already doing to Google, Amazon, Facebook, etc.
coliveira··on Fable 5.1 Solves the Cyphral Distich, a 370-year-old cipher
AI is the new god. People have started to believe that AI, when it finally arrives in its full glory, will bring some kind of salvation to humanity.
coliveira··on Music Theory for the 21st-Century Classroom
Yes, I think people have this fantasy that Jazz has anything new to offer in terms of music theory. That's false, everything used in Jazz was already part of the practice of classical music sometimes centuries ago. For example, improvisation was common in Mozart time and extended chords were common already in the 19th century. The only difference may be the terminology used in Jazz circles, but this is something that can be learned later if you want to specialize in that style.
coliveira··on DeepSeek v4.1 Flash
Some people are interested in making sure these simulations have the same status of humans, and some others want to make gods of them. That's the problem.
coliveira··on DeepSeek v4.1 Flash
Capitalism had already evolved into a religion, AI is their messiah.
coliveira··on DeepSeek v4.1 Flash
But the AI industry is not run by engineers. They pay engineers to do what they want, but the founders are hacks that are good at getting funding from investors and favors from government. That's why we don't see an engineering-oriented strategy in what they do.
coliveira··on Tao: Open math problems being non-renewably mined by AI
This to me is another level of dishonesty. Imagine if a company producing math software starts to hear "rumors" someone is using their software to prove an important result and start massive runs of that software to beat the team. That may not be illegal per se but it is incredibly deceitful. I wonder if the original mathematicians should start a lawsuit for theft of intelectual property.
coliveira··on Navier-Stokes – Tristan Buckmaster [pdf]
Exactly, especially when the company can assign "blame" to the models themselves "ops, they just escaped our commands not to store user inputs..."
coliveira··on Navier-Stokes – Tristan Buckmaster [pdf]
At this point these models have been trained to recognize every important math and science result based on context. They can easily flag conversations concerning the top 100 open problems in mathematics and use them for their advancement.
coliveira··on Navier-Stokes – Tristan Buckmaster [pdf]
Yes, and this puts in check the credibility of everything they say their model "discovered". Who knows what is really behind these "discoveries", what kind of backroom deals they did with other researchers who didn't have a chance or desire to disclose what happened?
coliveira··on CEO fired developers to make room for AI. Developers create open source AI CEO
A good CEO according to the market, which is what counts in the US, is one that drives up the valuation of a company and increases profit in a mature company. It has nothing to do with personal interaction as most of us would prefer.
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.
