LBarret··on Right or left, you should be worried about big tech censorship
Also what about laws and governments ? This is a very american perspective IMHO to miss this part of the picture.

Some stuff should be regulated. Especially post of FB/Twitter/ect that are actually provably false and whose diffusion are nothing but a carefully crafted op from a foreign country.

you could be concerned about over-regulation, but currently we are at the opposite side of the spectrum.

Asking FB/Twitter - or any company - to do the right thing and go against its own interest is simply naive.

LBarret··on Ask HN: What (side-)project are you working on?
Rectitude : a procedural generation editor for pixel art and generative art. https://lbarret.itch.io/rectitude

Starting to make cool stuff with it : - https://twitter.com/LBdN/status/1345931367738175488?s=20 - https://imgur.com/a/BJwZFdU

LBarret··on GameStop Is Rage Against the Financial Machine
It depends on how you shout. People won't stampede if they trust the leading authority, if there is credibility and competence.
LBarret··on Show HN: Books Paul Graham recommended on Twitter
PG wrote very very good books and essays.

But the current PG (esp on twitter) seems to be so far away from this level of quality that I see where you're coming from.

LBarret··on On Writing a C++ Book
Powerful doesn't mean fast. Python is quite slow but C++ is not powerful enough to make so many things usable without -comparatively- a lot of work.

C++ is very fast and entrenched in a few markets ( gamedev, trading, etc) but that's it. As a language it is quite average, encumbered by too many features, too many corner cases.

LBarret··on Ask HN: Recommend one book I need to read this summer?
This way of speaking is believable for Chinese scientists and militaries. The cop had a very different tone.
LBarret··on Ask HN: What are you working on?
I am finishing a procedural generation pixel-art editor, aka you connect nodes to get a rectangles of colour. The cool part is the nodes you use are often other graphs also built with the tool. It is a bit like Houdini but for pixel-art.

It is close to be a niche but solid product. I can reproduce with it a reasonable amount of the pixel-art I see daily. I am currently writing the tutorials for it.

The underlying engine is a restricted functional language and the architecture is based on streams of values. I am quite proud of the architecture because so far, I had very little accidental complexity to manage and that's key for me to stay motivated/productive on the project.

LBarret··on Callbacks in C++ using template functors (1994)
This is false in my experience (more than 10y). Most teams use a linter and a formatter. The situation is worse in any other language, except maybe golang.
LBarret··on Using Rust for Game Development [video]
I agree with you but this I am not sure it is the right example. In this case, the position of the zergs would be indirectly a component. You would have arrays of struct Zergs, each would only have a ref (or an index) to an arrays of positions. this array would be updated efficiently.
LBarret··on “I'm basically giving myself a permanent vacation from being BDFL”
yes, but that's so minor compared to the gain of a more readable syntax... really an edge case.
LBarret··on Ask HN: Have you successfully done a career do-over, and how did you do it?
I think conflating data structures and objects is bad, and muddle the discussion. An app is mostly a pipeline of functions over an initial data structure.
LBarret··on China forbids anonymous online posts
Such a biased/bad example...

This is a private affair, between the wife, the husband and you.

It can be a concern for the community but it has nothing to do with the government !!!

LBarret··on Ask HN: Is web programming a series of hacks on hacks?
this is a bit disingenuous. the back-end technologies are quite stable and based on not-perfect-but-reasonable semantics. Django/SQLALchemy don't change that much.

Front-end on the other end is a mess. JS/HTML/CSS as tools are clearly unfit for the current needs.

LBarret··on Ask HN: Is web programming a series of hacks on hacks?
look at elmlang maybe ? it solves a few of these problems, but this is quite different from what we are used to.
LBarret··on How I fixed a bug in Atom
you're not familiar with coffeescript and used to the many javascript warts, so your perspective is biased.

But Coffeescript makes many things easier and has good tooling (just another loader in webpack). While not perfect, It is a reasonnably efficient tool for front-end dev.

Try a tutorial, you may be surprised.

LBarret··on Uninstall Notepad++ if you have voted for FN
It is not forbidden, but it was condemned many times including for talk about concentration camps or jews. For a long time, it was borderline.

And It has a very dark history: - During the Algeria war, its founder (JM Le Pen), then in the army, used torture. - In the 90', the security force of the FN (Skinheads) killed a man (throwing him in the Seine).

Nowadays, its communication is way less agressive but it is the same core.

Currently, of its voters : - 92% thinks there are too many non-white people in france - 36% of its voters thinks some races are superior to others.

FN played its card well : it convinced many french that their current economic distress is caused by immigrants, Europe and anything coming from outside. Its political agenda is a big pile of fantasy about the France of 50' (powerful and white). And its economic program is laughable.

Well, that would be fun if it wasn't so serious and so sad.

LBarret··on Remove the ++ and –- operators
why ? Could you elaborate ?

Because from my point of view, it could be only the case only if the scopes are weak or underused, or names are bad (too short, ect). After SSA is all about one-use names.

LBarret··on Is the new Zuckerberg fake charity an estate tax avoidance scheme?
Maybe because his company (like google, etc) has a history of tax avoidance ? And paying tax is the first thing we do as good citizen.

Why believe a company like this ? Or the man at his head ? ( He has absolute control over FB so any decision made is under his control/responsibility. )

LBarret··on Paris Attacks Plot Was Hatched in Plain Sight
You have to draw the line somewhere. It is a balance between reasonnable information for the police and privacy.

Except when you're linked to an investigation, you don't have to proove you're innocent of any crime. Still, all those laws seems to think the opposite : police will have access to all your data like if you were convicted. Guilty until prooven innocent.

Beside, it's not like governments never abuse this kind of info.

LBarret··on f.lux for iOS is no longer available
This is a bit of a strawman argument, F.lux is not in this category of silly apps. F.lux is a reasonable app it has a good track record respecting its users and is requested by many many users. It is about control.
LBarret··on PyPy.js – PyPy in Your Browser
Except that for historical reasons, js is a very rushed/badly designed language. More precisely it mixes moment of brillance and very stupid design choices.

Ruby, Python, Lua are in term of language design way superior. Coffeescript and co emerges because it was more reliable to have a complex stack than to use the JS language directly.

That's the only high-level language that produced this situation. Python/Ruby & co are not perfect but good/reliable enough. You don't program in a another language that compile to python to avoid its verbosity and its traps.

If python had been choosen for the browser, we would have used for the last 15 years : module, sane scoping rule, classes, iterators, etc. Yep, that's something that it ecma6 without the ugly baggage.

15 years, damn it.

So no, please give at least Python in the browser and let people experiments with other language design choices and let them find something superior to Python. At one moment, it will be obsolete like any other tool. I don't want to be forced to use it because it is the only choice.

LBarret··on First chapter of Kernighan and Donovan's new Go book [pdf]
compare this with python, which has carefully evolved into a better language.
LBarret··on Linus on compiler warnings and code reviews
the choice is also between a good language and a bad one. Those two choices are not exclusive, and choosing good practices is not the end of the road for the quest for quality.
LBarret··on Rust bare metal on ARM microcontroller
I think rust people wants to proove repeatedly the addded value of their language : "no cost abstraction over bare metal" because it is the thing that will win the heart of their audience. Still, in practice, it will likely play as you say, but not now.
LBarret··on France bids to reverse tech brain drain
Between the natural grumpiness of french complaining about their country and the casual french bashing, it is hard to get some quality comments here.
LBarret··on France bids to reverse tech brain drain
Funny. I had to translate french document to get something from an american bank. Rigidity goes both ways.
LBarret··on France bids to reverse tech brain drain
This is misleading.

Many many countries are worse ...

And the level of bureaucracy is not the same everywhere in France. Education is a very conservative administration. Universities even more so, because they don't have much money (it's very different than in the US), so they stick to the process (with paper) they have.

In the private sector, this is quite different. Also many company-focused administrations (URSAAF, CIPAV) provides web site/app where you can manage your file. It is not perfect, but it's getting better every year. I think my accountant is doing 80% of her job digitally.

LBarret··on Unity Comes to Linux: Experimental Build Now Available
It is about the Unity editor. Unity3d can compile a game for a linux target, but until now, you couldn't design/edit/build your game on a linux machine.

This is great news and I hop they will support it.
