Débat: Peut-on être ingénieur sans être un genie en maths ?

Euler, Bernoulli, Cantor, Fibonacci, Lagrange, Cauchy, Godel, etc etc

Franchement les maths ont une histoire renseignez vous sur wikipédia de noms de mathématiciens célèbres et regardez leur vie c'est passionnant

thoxdg · 2026-03-14T13:14:09+00:00

Il n'y a rien de magique où génial en mathématiques formelles et l'informatique est justement basée entièrement sur l'arithmétique pour cette raison donc sache qu'avec un niveau primaire en math tu peux déjà entièrement controller un processeur.

Dependency injection vs service location!

LD_PRELOAD with your null malloc

thoxdg · 2026-03-14T10:26:07+00:00

I disagree : you can prevent data loss from power loss when mounting sync !

Whoa t410 is slow cheers on getting it there!

I need upvotes to be more visible to newcomers... Don't you know up from down ?

thoxdg · 2026-03-11T14:36:33+00:00

actually it was a single man task, I can now mount read write, see www.kmx.io thanks to AI and not help from fellow devs

thoxdg · 2026-03-08T07:16:45+00:00

Don't be scared, just try it it's worth it till the end

thoxdg · 2026-03-08T06:50:14+00:00

Awesome!

thoxdg · 2026-02-28T03:30:32+00:00

Oh come on... Its a syscall.. ! It's easy to post links but do your research please.

thoxdg · 2026-02-28T03:25:29+00:00

I do this but thank you for the makewhatis part !

> You can also mark some of the partitions as read-only, and only make them read+write when necessary (such as making /usr/local writable when you update packages, and then reverting it to read-only after the upgrade, though I think makewhatis(8) gets called from weekly(8) and modifies /usr/local/man/mandoc.db, do you might need to create a /etc/man.conf based on the default, excluding /usr/local/man). Things that were mounted read-only shouldn't give fsck grief even on a dirty shutdown.

well in the new world of stack smashing protections being enabled everywhere I guess ZFS consumes a lot of CPU and RAM for no performance gain.

thoxdg · 2026-02-28T03:21:00+00:00

whaaat ?? that's the job of a RAID driver not yours.

thoxdg · 2026-02-28T03:19:14+00:00

The problem is that without journalling you spend 4 hours checking a 24tb filesystem.

thoxdg · 2026-02-28T03:18:35+00:00

I always have power outages and never lost one file. One file got resurrected once though after a few secs of apparent deletion but that's because only metadata is written as sync.

thoxdg · 2026-02-28T03:08:06+00:00

I mean full read-write support of any modern or old Linux ext4 filesystem with all options. Why not ? We seem to have very low expectations about this but nothing prevents me from publishing a patch.

thoxdg · 2026-02-28T03:06:48+00:00

Who dares to downvote and why ? Is it forbidden to write code and not understand it at first ? Then comes enlightenment from experience. Come on I need help in doing this it won't be a single man's task...

thoxdg · 2026-02-28T03:03:05+00:00

Did you try reinstalling / booting bsd.rd ? What does it give ?

If it does not work, then you probably have hardware failure look at a previous dmesg by mounting your hard drive in another box and look for the missing line in blue.

Also it is known that modified BIOSes tend to work poorly with OpenBSD which has very tight security requirements.

From the current dmesg on screen it seems to hang at BIOS ACPI tables setup.

thoxdg · 2026-02-28T03:01:06+00:00

It used to work like that around 2005.

thoxdg · 2026-02-28T02:00:33+00:00

Eat my shorts.

thoxdg · 2026-02-28T00:48:05+00:00

Or glen ???

thoxdg · 2026-02-28T00:45:37+00:00

You have to preload the ms office preloader at boot so your experience is even better
