thibaut_barrere··on Why I wrote the BEAM book (2025)
I wrote it pre-AI, using cachex!

It is open-source:

thibaut_barrere··on Why I wrote the BEAM book (2025)
Sure, peaks are much higher. But a good part of it is reverse proxying with in-memory caching and locking, which I've implemented in several stacks over the years, and many struggle with it (I have been paid to do comprehensive benchmarks on the topic). On the BEAM it's a non-event.
thibaut_barrere··on Why I wrote the BEAM book (2025)
~160 req/s on average, higher peaks. Not trying to impress anyone though, my point was that LLMs work perfectly fine on an Elixir codebase, and that we get future-proof ops on a single node with zero issues. In my experience, it has been easier than with any other stack I've tried.
thibaut_barrere··on Why I wrote the BEAM book (2025)
Fair enough! That’s how we track growth, it’s easier to communicate to state sponsors.

Roughly 14M per day, but growing 2.5 to 3 on a YoY basis.

My point stands though: much more serenity in ops with that growth, and LLMs do work nicely, especially when most of the code is stateless by language design.

thibaut_barrere··on Why I wrote the BEAM book (2025)
I use Elixir (BEAM-based), with LLMs daily, on a fast growing site (current pace is 5 billion HTTP queries per year on a single front node).

Elixir is well handled by LLMs at this point, and we keep the “easy to scale and maintain” aspect (operational characteristics of the runtime are very good).

I can safely say that total cost of ownership is excellent.

Yes:

I planned to revive it later, but life got in the way

thibaut_barrere··on New 14‑inch MacBook Pro with M6
More people than you think (outside tech) are using Intel Macs at the moment (family computers etc).
thibaut_barrere··on Wages Fall to 43% of U.S. Gross Domestic Income, Lowest Since 1929
They (from the cases I know at least) already posted record profits with a lower inflation rate.
thibaut_barrere··on Google illegally cut down 250K trees in Finland for data center
It’s always the contractor!

Until it is not; some companies are actually putting environnemental & employees health issues with sincerity in their contracts. With shared responsibilities.

thibaut_barrere··on Google Cloud outage affects almost all banking and other operations in Europe
Indeed. The banks I deal with in France are unaffected.
thibaut_barrere··on Google Cloud outage affects almost all banking and other operations in Europe
This is being done while we speak here.

Happily hosting a site that will cross 4 billion queries per year there, and I didn’t face that banner you mention :-)

thibaut_barrere··on High Diesel Prices Bankrupted 16 Trucking Companies in Just 30 Days
Pressure on the road, and profits, are not similar to those induced by pedestrians and cyclists.
thibaut_barrere··on Microsoft director: AI scraping 'the largest theft of labor in human history'
Yes but there is a clear relationship between them in most countries!
thibaut_barrere··on Microsoft director: AI scraping 'the largest theft of labor in human history'
This is not how authors rights work
thibaut_barrere··on GitHub is having trouble counting things
Yes but in the case of GH, it also happens in cases where the data is old: not just a temporary drift.
thibaut_barrere··on LG TVs caught spying even when offline or on standby
The opt-in is bollocks. I am a LG owner and quite technical and used to legalese too. This will get them fined in Europe.
thibaut_barrere··on Pre-Release of Polars 2.0
I like when large projects do that. This gives leeway for sister projects (eg wrappers) to anticipate, room for apps that use it intensively to test things out (release candidate etc), something which has really helped me in the past.

In that specific case I use a Polars wrapper in Elixir (called Explorer) all week long, and I am very happy they are giving us early hints.

thibaut_barrere··on Early-life stress leaves a 'scar' inside brain cells in mice
I do not read this in the article, I was more understanding that half the kids of the world could be concerned to a level or another, can you quote?
thibaut_barrere··on An update on leaving Gmail for Fastmail
I made a preliminary attempt as well and had the same experience. I hope to renew with a better success.

Just in France, cost of this year heat waves has been estimated between 10 and 15 billion euros (figure shared by a ministre today).
thibaut_barrere··on Delphi 13 Community Edition Is Now Available
Even before, Turbo Pascal was fairly appreciated in some circles (e.g. demomaking), quite productive and nice to use!

Some people tend to forget that you got to start somewhere, and a lot of huge undertakings started this way. Such as Linux ;-
thibaut_barrere··on U.S. used 'virtually all' of its long-range precision missiles during Iran war
It turns out public money is more expensive these days. Debt is a more mainstreamly exposed problem.
thibaut_barrere··on Solid Queue 1.6.0 now supports fiber workers
Same path & agreed. The amount of things you do not have to care about with BEAM/Elixir compared to Rails is really interesting.
thibaut_barrere··on JEP 401: Value Objects (Preview) merged to OpenJDK master
Yes, massive respect for that type of perseverance on long term, important changes.

It is one of these instances where « let the market decide » is not necessarily the best option on the long run.
