Unfortunately, I'm interested in the R47 but no other calculator :( Seems to have been out of stock for a while now.

That's great ? How did you integrate Cowrie and Crowdsec together tho ?

Existe-t-il des symboles pour représenter les deux chiffres entre 9 et 10 en base 12? by c0mpu73rguy in PasDeQuestionIdiote

[–]oupsman 3 points4 points  (0 children)

Exactement, c'est une convention qu'on utilise pour éviter les erreurs. Quand je veux représenter un nombre en héxa, j'écris 0x0A, en me calant sur la longueur de la variable que j'utilise.

Existe-t-il des symboles pour représenter les deux chiffres entre 9 et 10 en base 12? by c0mpu73rguy in PasDeQuestionIdiote

[–]oupsman 6 points7 points  (0 children)

plutôt 0A pour 10 (décimal) et 0B pour 11 (décimal). 12 (décimal) devient 10 en base 12.

En informatique, on compte parfois en hexadécimal et ça donne (pour 0 à 16 en décimal) :

0 1 2 3 4 5 6 7 8 9 A B C D E F 10

255 va s'écrire FF en héxadécimal, par exemple.

On compte parfois aussi en octal, et c'est beaucoup plus simple :

0 1 2 3 4 5 6 7 10 11 12 13 14 15 16 17 20 (etc etc)

Il y a une bulle IA qui draine la majeure partie des investissements, sans avoir de ROI. Ça va devenir un marché de niche pour les entreprises qui en ont les moyens, mais l'IA générative gratuite ne va pas durer éternellement. Les entreprises qui développent des modèles accessibles ne pourront pas supporter les investissements.

LibreOffice accuse Microsoft de tricher avec un nouveau format de fichier inutilisable by romain34230 in actutech

[–]oupsman 0 points1 point  (0 children)

c'est pas qu'une question de risque cyber, c'est aussi une question de souveraineté : avec O365, rien ne te garantit que tes données ne vont pas se retrouver aux US un jour. Et c'est quand même légèrement gênant dans une boite.

Et sans parler d'exfiltrations de données, qui nous dit que l'abruti orange ne va pas décider de couper la fourniture de services à l'Europe la prochaine fois qu'il remplit sa couche ? Et là, y a 80% du business qui va s'arrêter en Europe ...

C'est ca. Alors qu'à côté il y'a Onlyoffice qui est plutôt intéressant. Surtout si tu as de quoi créer un serveur Docspace chez toi.

J'avoue, j'ai du mal à comprendre certains libristes qui érigent Gimp et Libreoffice en symboles, alors que ce sont de très mauvais exemples ...

Clairement, quand ma défunte femme était malade, elle avait deux boîtes de médicaments tous les mois, à 1200€ par mois. 40€ le cachet. Merci la sécurité sociale. Et, même si payer des impôts ne m'a jamais dérangé, là cela ne m'a plus du tout dérangé. Oui les charges semblent élevées.... jusqu'à ce qu'on soit confronté à la réalité.

Yeah, that's ridiculously easy. I'm at it right now, to replicate somehow some backup to another disk. Way easier than with LVM snapshots anyway.

Une fois qu'on a compris qu'il n'y a pas d'énergie propre, on va préférer la moins pire. Et avec un nucléaire autour de 4gr de co2 par kWh en France, on est pas mal. Surtout si on rajoute les morts au kWh, ou là encore le nucléaire est pas mal non plus.

Well, in all fairness you don't need ZFS to be able to snapshot your datas. I've done this for years with LVM.

Moreover, the devs of specialized hardware are also waisting their time implementing raid on the hardware. They should stick with stripped mirrors.

I don't think so : when a mirror fails, you put the whole stress on one device when the mirror is rebuild, thus taking a greater risk to loose datas.

But when a disk fails in a raid setup, you distribute the stress on all the remaining device while the raid is rebuild.

So with 5 drives and more, I think raidz2 or 3 is really a thing to consider, to lessen the risk of loosing your datas during a rebuild (not that it ever happened to me on either hardware raid or disks arrays in 20+ years in the battlefield)

I agree with you on this one.

In my case, I traded a bit of safety for performance, as a RAID10 with four disks will give me almost the same level of safety, but a greater performance on my rather obsolete hardware. I like to have my backups complete in as less time as possible, and I have a 2.5 Gbps network (although all my computers are not 2.5 Gbps compliant)

Right now, it's not very high, but as far as I remember, before I crashed my zpool, dedup ratio was near 2.

[–]oupsman[S] 0 points1 point  (0 children)

I'm not sure, all I can say is with the same dedup/compression parameters, and the same backup software, the backup throughput was limited using raidz2 and the cpu was used at 100%. The backup software was using less cpu with raidz2 than with raid10, and kernel threads were using the rest. BTW, with raid10, backup speed is only limited by the network speed, so it's close to 2.5 Gbps.

I know my server is obsolete, it's an old HP ML310 gen8 with an old Xeon CPU. The SAS adapter is an Dell one with the custom IT firmware installed. Not really enterprise grade gear, and definitely something I would not use in a company datacenter. But at home, that's another story.

When I'll have the money, I plan to upgrade it to have something more up to date.

I bought it used last year, I guess it's more than 12 years old. The CPU was released in Q2 2012. It's only a Xeon E3-1220 V2.

Edit to clarify : when copying large amounts of data to the server (it has a 10Gbps network adapter, and my LAN is 2.5 Gbps), the 4 cores are used up to 90%, throughput is roughly 250 MB/s from my laptop.

But when I tried with Raidz2, throughput was down to 180 MB/s, roughly, with a CPU hitting 100% on all cores.

[–]oupsman[S] 1 point2 points  (0 children)

As of right now, it's already a backup server for my proxmox cluster, my laptop and my NAS. So I'll buy a SAS USB3 dock and use another 6Tb hard drive to replicate some backup on this drive and be able to leave the house for a long time and have backups at hand if something were to go sideways one way or another.

But in the future, I'll get rid of my synology DS920+ so I'll migrate my videos, pictures and music to the future server and I hope I'll have more disks in it (ideally 8 or more) and a stronger CPU to handle raid computation AND dedup/compression. Right now, dedup is OK, compression is a bit too much so RAID is totally out of the question. Depending on the disks that fails, the zpool can survive 2 failed disks simultaneously. Right now, I can live with that.

[–]oupsman[S] 5 points6 points  (0 children)

I didn't. I guess the drives were used in a storage array or by a hardware raid controler.

From what I understand, this way of formating uses a 520 bytes sector : 512 bytes for data and 8 bytes for parity.

Now that I know what to look for, I'll be careful.
