Makefiles fasten compilation.
GCC/binutils apart, compiling #Jehanne from scratch take 2 to 3 minutes. A whole operating system, including kernel, userspace programs and all.
When makefiles where invented compiling and linking a simple hello world used to take minutes, so it was rational to spend computing cycles to minimize the amount of compiled code keeping track of the modified files and their dependencies.
But is this still true today?
To be honest, I don't think so.
Today makefiles and similar tools are used to tame the huge complexity of big codebases, while the right think to do would be to avoid writing such big codebase from the beginning.
That's basically why I did't port neither gnu make nor plan9 mk to #Jehanne: I don't think we should still use them.
In other words, I would suggest you to use a simple lisp (or rc, or sh or... whatever) script to build your code instead of make and similar tools.

While we shouldn't waste energy as if it was an unlimited resource, we should be careful with performance optimization.
We should ban #blockchain technologies as soon as possible, but we should also note that #BigTech married the greenwashing thread long ago.
They can offer "green" computation on a scale by cutting from their carbon footprint the energy consumed by the connected clients (mostly browsers).
This is obviously unfair because they control such client-side computation in several ways, including by controlling the browser development, the standards and the frameworks used to build upon them (#React, #Angular and so on...).
Not to mention the actual decision of which version of the code you run on your browser, that can be "personalized"/targetted just like ads.
So ultimately they lie, as usual.
BUT arguing about performance and energy consumption might end up supporting their rhetoric.
So sure, compiled software is more efficient then interpreted one, but (first) you need to consider the whole computation, including remote client and data transfer, and (second) you need to compute the optimal balance between the pollution of the biosphere and the predation of the cybersphere.
Amazon might even (pretend to) provide the most energy efficient computation, but in the end they would use the power provided by the data collected to move goods around the world in a very polluting way.
Actually, I wonder if the constraints that made makefiles a good solution are still there.
@ariel@m.costas.dev
"Fast" is arguably a #BigTech concern, not something Aral (or me) would give a shit.
Simplicity however is very important, in different ways, for both of us.
However when you try to figure out how simple is your software, you cannot ignore the stack you are using.
How many milions of lines of codes are behind those 100 #javascript ones?
This obviously apply to any stack, go, python, perl, lisp... even C!
Hidden complexity is not simplicity.

Coming up on 1 year on the fediverse.
I started out self-hosting my services with a nextcloud. It was really great having access to a service like that anywhere I went. It was a shock to realize that when you run your own service you can use it however you like -- there's no admin to complain that you're not using it the way they want.
Shortly after, big tech started their shenanigans in earnest -- Once they've banned the sitting president of the united states, there's no chance of escaping the censorship.
I started out on alt tech, minds and bitchute. They were fine, but you could see that all it would take is someone to change their minds about how to run the site and suddenly we're back to square 1. On supposedly free-speech minds, one of my posts got reported and at that point I just wasn't interested anymore.
Around the same time, Google had been warning they were going to shut down hangouts. Over my life, I've had a lot of services I use shut down or change such that I can't use it anymore, and it's getting annoying.
I started to go about figuring out how to start up my own service.
I tried Friendica at first. There are some things I really liked about friendica. Once I got the interface working the way I liked it was definitely a looker, and I still prefer the way it shows threads by default. Unfortunately, I found that friendica was very heavy on the back-end to the point that I wasn't able to know for sure if my posts were getting out there. If I had a beefier server it probably would have been fine, but I didn't.
Next I moved to pleroma, and it was much more responsive.
Today I'm running pleroma on the back-end with soapbox-fe as my front-end. Along the way I also set up a peertube instance, a searx instance, an invidious instance, a Matrix homeserver, an xmpp homeserver, and a lotide instance.
It's really cool! Essentially, most of the tabs I have open now are from my own services.
There's lots of interesting people on here so content isn't really a problem. Some people have reported my posts, but that's because they're literally stupid. Every report I've seen is "I disagree with this guys politics!" which was summarily ignored.
The only service I still routinely use from big tech is youtube, though now mostly through my invidious instance. I spend a lot of time on my peertube instance, however.
I'm pretty sold on the fediverse ecosystem at this point, and I'm totally sold on self-hosting. Nobody will get rich off of it, but what I envision is someone coming up with a box that you can install in your house that will allow setting up and maintaining self-hosted services automatically, and then everyone would be independently using their own services that communicate with others' self-hosted services.
I grew up on the Free Internet. I don't care to live on the locked down Internet. I like seeing ideas I don't agree with. I like seeing things that make me feel uncomfortable. I like seeing things I think are wrong. I like seeing things that make me think and maybe change my own views. This is the last best bastion of freedom left.

@minimalprocedure@mastodon.uno La scuola e l'università potrebbero, ma - salvo eccezioni - in Italia sono fra gli enti che aderiscono e favoriscono l'assuefazione agli oligopoli proprietari.
Individualmente tento di farlo https://elearning.sp.unipi.it/course/view.php?id=554 sfruttando l'articolo 33 della costituzione, ma questo significa venir sistematicamente emarginati da coloro che si sono adeguati all'idea che il modello del docente universitario debba essere il ragionier Filini.

Non è impossibile evitare di sottomettersi a GAFAM https://peertube.devol.it/w/89XNjqjPTXaMVdWsoR3ZzN Ma come trasformare le scelte individuali in scelte collettive, soprattutto per chi lavora in istituzioni e aziende che fanno l'opposto?

Andrea Lattanzi è il vincitore della quinta edizione del premio giornalistico under 35 Letizia Leviti, la cui cerimonia si è svolta a Palazzo Vecchio alla presenza del sindaco di Firenze Dario Nardella. Lattanzi ha ottenuto il riconoscimento per l’articolo pubblicato su La Stampa dal titolo "Una vita senza Big tech, storie di chi cerca alternative ai giganti del web: non barattiamo i nostri dati per i loro servizi". Nella motivazione si legge che il lavoro di Lattanzi "è un lavoro ‘politico’, nel senso più alto del termine. Un lavoro di visione, di concetto, che ci dimostra come, anche in questi anni che viviamo, ci si possa ’slegare’ dai vincoli della tecnologia.

(little implicit premise: when I say "fork" I mean Plan9 style rfork, that let you specify what is inherited by the parent process... except for the stack, which is inherited anyway)
The fact is that both inherited memory and `malloc`ed one (and even `mmap` one in linux, afaik!) is just a promise you get from a cheating kernel: the physical memory is NOT assigned to the process until the last possible instant (the memory access fault).
In #Plan9 this is also true for the stack that is handled as copy on write, but I'd guess on #Linux and #BSD, all other segments are CoW too.
Also in a Plan9 system, pages are 4096 bytes chunks, so the CoW is pretty conservative and after a fork only one new physical page is assigned to the new process (the page where the return value of the fork syscall get written).
So, in theory, fork is not that coarse memory hungry faggot.
But AFAIK this happens with malloc too: pages are assigned to processes only on read/write faults. In modern systems memory is always overcommitted.
It is dangerous, but consider the alternative: most allocated memory would stay unused and you could run a fraction of the programs you run on the same hardware.
Well, this is a good answer, but in fact, on plan9 you only get a new process: memory is only copied on write.
So it's not necessarily a malloc.
Also rfork give you a good degree of control on what is copied.
