so on my new lappy I'm testing XFS. After reading how bloody fast it is, I figured: why not give it a shot!
2 weeks later, I want to go back to ext4. XFS is SSSSOOOOOO fault-intollerant, it breaks my Chrome profile after each forced-poweroff (or power loss). And the on-boot fsck freezes. And after a successful bootup I see the log messages in syslog are all messed up (timestamps are all over the timeline!!!)
it's a mess... A very fast mess.17 -
Hey lads and gals!
A genuine question to people who live in "heaven-on-earth" countries (Greece islands, Italy, Spain seaside, Portugal, etc.). Where do YOU travel to to chill, change scenery and relax?
I mean, for us, wildlings of the North, going South on vacation is a no-brainer. Like now, I'm getting my sanity back while sipping Rakia (IDK why not ouzo though..) in Crete. But where do Cret(ians?) and other Southerners go on vacation?5 -
I may have accidentally found a legit factorization method that converts factoring to a combinatorics problem over a graph, with a time complexity that is the factorial of the logarithm of the semi prime being factored.
I don't know if this is supposed to be good or not, and I don't want to post it prematurely like I almost always do. Not at least until I study its properties better, but it's still a pretty interesting find I think.11 -
After a lot of work, the new factorization algorithm has a search space thats the factorial of (log(log(n))**2) from what it looks like.
But thats outerloop type stuff. Subgraph search (inner loop) doesn't appear to need to do any factor testing above about 97, so its all trivial factors for sequence analysis, but I haven't explored the parameter space for improvements.
It converts finding the factors of a semiprime into a sequence search on a modulus related to
OIS sequence A143975 a(n) = floor(n*(n+3)/3)
and returns a number m such that n=pq, m%p == 0||(p*i), but m%q != 0||(q*k)
where i and k are respective multiples of p and q.
This is similar in principal to earlier work where I discovered that if i = p/2, where n=p*q then
r = (abs(((((n)-(9**i)-9)+1))-((((9**i)-(n)-9)-2)))-n+1+1)
yielding a new number r that shared p as a factor with n, but is coprime with n for q, meaning you now had a third number that you could use, sharing only one non-trivial factor with n, that you could use to triangulate or suss out the factors of n.
The problem with that variation on modular exponentiation, as @hitko discovered,
was that if q was greater than about 3^p, the abs in the formula messes the whole thing up. He wrote an improvement but I didn't undertsand his code enough to use it at the time. The other thing was that you had to know p/2 beforehand to find r and I never did find a way to get at r without p/2
This doesn't have that problem, though I won't play stupid and pretend not to know that a search space of (log(log(n))**2)! isn't an enormous improvement over state of the art,
unless I'm misunderstanding.
I haven't posted the full details here, or sequence generation code, but when I'm more confident in what my eyes are seeing, and I've tested thoroughly to understand what I'm looking at, I'll post some code.
hitko's post I mentioned earlier is in this thread here:

I’m expanding my storage with 8x 20TB hard drives. With raid5 on it I would get approximately 126TB of storage space.
This would allow me to download full common crawl dataset and play with it locally.14 -
As its now customary for kids of her age my 9 years old cousin received her first phone. Said phone has just 32gb of internal storage and her continuously putting games on it doesn't help so it constantly gets full and since I'm family's tech guy I'm the one who get called for that... I'd really love to destroy that waste of silicon by throwing it under a bus and then give a Nintendo Switch to my cousin as a better replacement. I hate these Android devices that are obsolete even before they hit the market but most importantly I hate the fact that 9 years old get "smart" phones for no actual fucking reasons.8

What do you think about Dart? They pitch it as an elegant language for everything: browser, WASM, servers, plus every native platform with Flutter.4

Windows XP was just right. A perfect balance of performance and functionality.
Everything less complex feels too impractical, everything more complex feels too uncontrollable.
When using XP, I was confident I could get the job done, yet I knew what every process in the task manager did. It’s not the case with 7, let alone 10/11. I don’t know what happens under the hood there at all. Maybe custom Linux distros qualify too, but they’re unapproachable by laypeople. You have to be a geek to use them effectively.
Windows XP struck just the right balance between functionality, simplicity and compatibility. Too bad the era is gone in favor of opaque surveillance.9 -
I'm stuck.
Quitting smoking/scrolling/youtube/other unhealthy coping mechanisms, taking my prescriptions and exercising every day made my mind free — now it's unobstructed, clear and not hindered in any way.
The problem is, without constant coping, my memory turned into a minefield. I can't think freely, as I constantly stumble upon trauma after trauma that make my heart physically hurt.
With clear mind, I now clearly see what used to lurk in shadows, and I'm terrified of it. I won't go back to smoking and watching youtube ten hours a day.
What should I do?13 -
There are only 15 devrant++ users :(
I remember times where the list contained so many people that it took very long to count the number of devrant++ users15 -
I worried i would be jobless for six months. Ok i applied at at least 20 different companies but i’m only jobless for two weeks now =D

Modern title inflation is a piece of shit.
Story time: recent hire from MANGA with multiple (!) AWS certificates.
Spent almost the whole day setting up a simple (one DB to another) replication with AWS Database Migration Service.
Never finished, lied that finished and run simple backup-restore.
I spent 15 minutes configuring migration and 30 minutes running full load + started ongoing replication.
The part of "ongoing replication" was done with cronjob + backup-restore.
Knows dogshit.
Overinflated ego, and organization now need to spend time and money to deal with the person.
Attrition continues...1 -
Finally got the opportunity to work as fullstack more oriented to backend as a side gig and I fucking love it.
Now I can say with all my heart that I hate my main frontend job and designers so much. I hate every small task like:
- change this arrow
- change this button
- change this color
- well this is not accessible.
- well this doesn't pass contrast check ( as if this is my fucking job and not the stupid fuck designer who mixes up colors )
Now I'm just trying to consider a reconversion and git gud .1 -

Hello there!
I'm going insane...
For years, ever since she's had a Laptop and a smartphone, my grandmother complains that they're slow.
Every few weeks she's like "yeah transfer all my photos from my phone to the laptop"
Okay, sure...
Laptop: windows 10, 500GB HDD, I3-2330M, 4GB DDR3...
It's constantly maxed out with everything. Booting up takes >4 minutes, transfer rates from her fuckPhone are around 2.4MB/s if you're lucky.
I keep telling her, for years now, to invest in a new laptop and phone, since her smartphone has only got 8GB of usable space, most of which (>5GB) are used by her fucking apps and partly by the OS.
She's, what I like to call "Beratungsresistent", roughly translates to "Resistant to suggestions/counseling/trying to genuinely help her".
I'm seriously getting sick of it.
I told her in December of last year to make a budget plan and I'll get her a well-performing laptop and phone with it.
"Ughhh, everything will be so different..."
HOLY SHIT I KEEP TELLING YOU I'LL PUT WINDOWS 10 ON IT, THE SAME OPERATING SYSTEM AS ON YOUR CURRENT PIECE OF SHIT LAPTOP AND YOU'RE NOT GONNA HAVE TO RE-LEARN USING AN ANDROID!
She's not stupid, but fucking lazy. She genuinely doesn't give a flying fuck about her devices until they start getting slow. I TOLD HER A BILLION TIMES THAT THIS IS WHAT SHE'LL HAVE TO LIVE WITH IF SHE DOESN'T UPGRADE HER HARDWARE OR GET A NEW DEVICE!!! LIKE HOW ARE YOU SO FUCKING DENSE NOT TO UNDERSTAND THE IMPLICATIONS OF AN HDD VS AN SSD AFTER I EXPLAINED IT A THOUSAND TIMES!
IT'S ALWAYS THE FUCKING SAME, I AM SUPPOSED TO MAGICALLY MAKE HER DEVICES FAST AGAIN, BUT I CAN NOT, FOR THEY NEVER WERE!!!
I feel like I'm about to explode at some point. It's the same thing every couple of weeks right after I come home from work and want to have a relaxed evening from a stressful job.
Rant over, have a good day.5
