pdhborges··on Rails World 2026 Opening Keynote [video]
If it doesn't matter I will just pick the cheapest to run (the static ones).
pdhborges··on After Math
We also use technology to care for the people in medicine and it requires pretty advanced science and engineering. Doesn't that shred your argument?
pdhborges··on You Don't Need Matrix Calculus
OP was talking about this: https://www.math.uwaterloo.ca/~hwolkowi/matrixcookbook.pdf

Look into some examples of the section 2.4 "Derivatives of Matrices, Vectors and Scalar Forms"

pdhborges··on Mistral raises €3B
I took it in good faith I just think that:

- the overregulation narrative conflates two different problems

- and that you minimized too much the consumer benefits of EU legislation

I think the overregulation problem olis less that we have 200 EU regulations and we need to hack and slash 100 of them and more that we have 100 national regulations 25 are exact transcriptions of EU directives, 25 are transcriptions with tweaks and the other 50 are national scoped regulations and what we need to do is to make them uniform so that companies don't have to deal with 27x75 problems.

I'm a bit burned by politicians using the overregulation narrative and then not specifying a single example of a meaningfull rule that they would get rid of. Usually what is left in the air is that worker rights and consumer rights should be cut.

Do you believe I can't get a list of 20 effective pro-consumer regulations drafted by the EU out of Gemini?
pdhborges··on Air Conditioning Is Not a Luxury, It Is a Necessity
This was an half usefull joke. I can still make it with the exterior unit off for an extra 1 or 2 degrees with just the interior unit blowing during the day and the use the AC to cool during the night when it is more efficient.

In any case where I live fans are not a meaningfull stopgap measure.

pdhborges··on Air Conditioning Is Not a Luxury, It Is a Necessity
You can use your AC as a fan when it is not too bad.
pdhborges··on CEO fired developers to make room for AI. Developers create open source AI CEO
> A very personal view but many developers/engineers fail to see the overall picture. And yes, I was there and I went through all of the mistakes.

What is failling to see the overall picture? I hate this overall picture mysticism. I bet that if people where given the same role and information as the CEO they would be able to see the overall picture.

pdhborges··on Mathematicians will probably become obsolete before anyone else [pdf]
I think it is time to repost Against Curry-Howard Mysticism (https://liamoc.net/forest/loc-000S/index.xml)
pdhborges··on Linear algebra done right
Sorry to bother but is there hope we are going to see Practical Math for Programmers published any time soon?
pdhborges··on Linear algebra done right
Is this the book you are referring to? https://epubs.siam.org/doi/book/10.1137/1.9781611977448. It has 991 pages, not exactly what I would call concise.
pdhborges··on Is the industry ready for tokens-constrained work?
What large parts of the world? Some places in Canada, the US, an handfull of countries in Europe, Autralia plus a few hotspots in SEA?
pdhborges··on Is the industry ready for tokens-constrained work?
Sure in the US. But people are throwing token caps in 500, 1000, 2000 dollar range here. That is a very significant expense on top of salary, taxes and benefis. It's only justifiable if they observe 20% 30% or more productivity increases across the board.

If you have huge salaries, yeah sure 500 dollars its okay even if you only get 5 10% more productive.

pdhborges··on Is the industry ready for tokens-constrained work?
You have people in Spain and Portugal hiring juniors at 25k per year.
pdhborges··on Is the industry ready for tokens-constrained work?
I took into account all of that. Still ridiculous.
pdhborges··on Is the industry ready for tokens-constrained work?
10 grand a month for a junior is absolutely ridiculous in most of the world including large swats of the western world.
pdhborges··on Codex in ChatGPT desktop app for Linux is now in preview
For someone who has not tried these desktop apps: what is the the advantage versus cli codex with some MPCs and multiple folders each one with their context files?
pdhborges··on “Code was never the hard part” is an insult to all programmers
Even if you get a crispy set of requirements from all parties you are still responsible for implementing all of then while making sense of the existing system (and from my experience significant issues arise at this stage when the full extent of requirement implications ia better understood). On top of that you might also be responsible for operating the thing, participate in compliance doc writing and do ongoing maintenace.
pdhborges··on Danish high schoolers will have to verbally defend written assignments
I'm also surprised. In Portugal primary, middle and high school tests and exams are all proctored and the vast majority of them written by hand.
pdhborges··on “Code was never the hard part” is an insult to all programmers
Touch billing, touch medical data, be at a B2B company that needs to catch all the ISOs to have a chance to land bigger contracts. I don't think it's uncommon.
pdhborges··on Denmark Requires Oral Defenses for Students' Written Work to Counter AI Cheating
Are you willing to pay to learn remotely from a university with crappy reputation?
pdhborges··on Managing AI Coding Costs at Scale

   I have a hard time believe their time is worth less than $75/hr or so.
In many places in Europe it is.
pdhborges··on Eight Myths on Software Engineering and GenAI
Can you imagine scenarios that would make it less silly? I will give an example:

- The AI researcher might be working for a lab or company with much less funds than the top dogs. Are they likely to discover something that is worth it before a bigger model becomes more capable?

pdhborges··on Andy Pavlo joins ClickHouse to establish ClickHouse Labs
To be honest none of these problems feels remotely "solvable" beyond having a ton of knobs and engineering tradeoffs like we already have now.

In a sense they don't seem very exciting because all of this required generality.

pdhborges··on The Maxwell Conjecture Is False (GPT 5.6 Sol)
At least in europe you can do a 3 year Eng Phys BSc and if it doesn't pan out you can do a master in EE or MEng.
pdhborges··on AI revenues are growing fast, but not fast enough
Maybe people believe that the process complexity is not symetric. I don't blame them. Building an house is more complex than destroying it.
pdhborges··on Some more things about Django I've been enjoying
Well whether it's better or worse depends on your specific situation.

What I'm facing right now is a 10 year monolith modularized with applications. Like a sibling comment already discussed these applications are not reusable application so almost all advantages of having that are moot.

Now, the consequence of having this structure is that we now have complex dependencies between the migrations of these apps i.e. cyclic dependencies, dependecy constrains that are underspecified. Thousands of migrations that now take a significant amount of CI time. We would like to squash them but it requires a lot of review and manual work and if we keep using multiple apps we are going to ave the same problem in the future.

The only meaningfull gain we had with multiple apps is that we have less migration conflicts when people create migrations concurrently.

Is that advantage worth the pain? I don't think so.

pdhborges··on Some more things about Django I've been enjoying
You don't have to put all your modules into a single file. You can break them into multiple files and the import them into a model file just so that Django loads it from the expected location.

Instead of apps you can just split your components inside a single app using regular python modules.

pdhborges··on Some more things about Django I've been enjoying

  - Django apps are an anitipattern for large internal / single purpose products due to migration overhead as FKs cross application boundaries
Totally agree with this. Now we have thousands of unsquashable migrations that require a ton of work to fix.
pdhborges··on Factories are just rooms
I think the mindset is usefull personally. When large complex systems are required and economic pressure is applied it can rapidly turn into an dangerous strategy. You will quickly realize that no you can't just build that.
