@maciejwalkowiak Totally unrelated question, but what monitoring too do you use to graph metrics per deployment version?

@zack_overflow @penberg Would it be interesting to have a rust linter rule to make sure an allocator is passed as a parameter upfront for some projects?

Certes, l'Allemagne n'a jamais produit d'électricité plus "proprement" que la France en 2023. Pas une heure.

Mais pire : leur meilleure heure de l'année est moins propre que la pire des notres.

Which technology is this?

Aujourd'hui, j'ai appris que le village de Viganella, dans les Alpes italiennes, ne recevait PAS la lumière directe du soleil, 83 jours par an, à cause des montagnes. Ils ont installé un miroir de 8x5 m piloté par ordinateur qui reflète la lumière du soleil sur le village 6h/j

Why is it mostly blue checkmarks who form those uninformed opinions...

[ry @rywalker]

I posted to LinkedIn recently:

"Learning Java is a waste of time for today’s college students. It’s not applicable to today’s cutting-edge tech market anymore." and got a lot of disagreement.

So let's dig into that hole deeper :)

@penberg Nice!

The comments under my Latest Video revealed a disturbing thing...

Ok, Vim users. How many of you knew about the Ctrl+F?

Control flow considered harmful

[Pierre Terdiman @PierreTerdiman]

Unpopular opinion:

"continue" and "break" are just "goto" with an implicit jump address left as an exercise for the readers.

Sometimes the explicit jump target of "goto" can actually make the code flow easier to read.

Array allocation style: multiply by 2 until it fits your workload

[Nikki Pinski @pinskinator]

Every software engineer's nightmare.

"and how did you calculate this thread pool size?"

Uhhh

"was it the result or a thorough analysis and load test?"

Yyyyees.

"can we see the results?"

Nnnno.

@tsoding `filter level >= "WARN"` is convenient though

[👩‍💻 Paige Bailey @DynamicWebPaige]

warning: very biased opinion

but, for developer tools: you don't need a "PM"

you need "an empathetic engineer, who is so frustrated with the experience of doing their work that they're willing to become a PM to change the state of the world for themselves and their colleagues"

@ahachete I have a theory that people disdain for the JVM is rooted in disdain for bad java code bases.
When you dig into it, JVM is clearly a marvel of engineering.

Waiting for tech twitter to challenge the assumption that teams should work on more than one computer.

[Loïc Carr @dimtion]

If you use git, on a team with more than 1 computer, there are always multiple branches. Whatever your flow be.

[Sidu Ponnappa @ponnappa]

Repeat after me: Branching is for low trust code contributions in low trust teams. Branching & CI are mutually exclusive.

Some reasons to branch:

- unknown contributors (oss)
- a tech stack that's intrinsically fragile
- external compliance
- poor quality control practices

Just blogged: "Linear code is more readable"

@muratdemirbas Tbf the reason we should not deploy on Friday is because debugging a prod issue over the weekend is very annoying.
If the issue only manifest on Monday, it would be a business as usual.

A language which is safe to forget the variable names.

[Armin Ronacher ⇌ @mitsuhiko]

I would be super curious what everybody’s definition of a memory safe language is.
