Exciting news for who? Only the site owner is excited that a free resource now requires a subscription

"Yay! Now I have to pay another subscription! I'm so excited! Let's celebrate with them!" - nobody

So, I moved my nextcloud directory from a local SATA drive to a NFS mount from a nvme array on a 10G network

"I just need to change /docker/nextcloud to /mnt/nfs/nextcloud in the docker-compose.yml, what's the issue, i do it live" - i tell myself

So i stop the container, copy /docker/nextcloud to /mnt/nfs/nextcloud, then edit the docker-compose.yml... and.... because I'm doing it during a phone call without paying too much attention i change the main directory to /docker

I rebuild the container and I immediately hear a flood of telegram notifications from my uptime-kuma bot.... oh oh...

Looks like the nextcloud docker image has an initialization script that if it doesn't find the files in the directory, it will delete everything and install a fresh copy of nextcloud... so it deleted everything on my server

Luckily i had a very recent full borg backup and i'm restoring it (i kinda love-hate borg, i always forget the restore commands when in panic and the docs are a bit cryptic for me)

Lessons learned:

1. always double check everything

2. offsite backups are a must (if i accidentally wrote / as path, i would have lost also the borg backups!)

3. offsite backups should not be permanently mounted, otherwise they would have been wiped as well

4. learn how to use and schedule filesystem snapshots, so the recovery wouldn't take ages like it's taking right now (2+ hours and i'm not even half way...)

So, i got persuaded to switch from a "server that is going to do everything" to "compute server + storage server"

The two are connected via a DAC on an intel x520 network card.

Compute is 10.0.0.1, Storage is 10.255.255.254 and i left the usable hosts in the middle for future expansion.

Before I start to use it, I'm wondering if i chose the right protocols to share data between them.

I set NFS and iSCSI.

With iSCSI i create an image, share that image on the compute server, format it as btrfs, use it as a native drive. Files are not accessible anywhere else.

With NFS i just mount the share and files can be accessed from another computer.

Speed:

I tried to time how long it takes to fill a dummy file with zeroes.

/iscsi# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=250000 && sync"
250000+0 records in
250000+0 records out
2048000000 bytes (2.0 GB, 1.9 GiB) copied, 0.88393 s, 2.3 GB/s

real    0m2.796s
user    0m0.051s
sys     0m0.915s

/nfs# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=250000 && sync"
250000+0 records in
250000+0 records out
2048000000 bytes (2.0 GB, 1.9 GiB) copied, 2.41414 s, 848 MB/s

real    0m3.539s
user    0m0.038s
sys     0m1.453s

/sata-smr-wd-green-drive-for-fun# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=250000 && sync"
250000+0 records in
250000+0 records out
2048000000 bytes (2.0 GB, 1.9 GiB) copied, 10.1339 s, 202 MB/s

real    0m46.885s
user    0m0.132s
sys     0m2.423s

what i see from this results:

the sata slow drive goes at 1.6 gigabit/s but then for some reason the computer needs so much time to acknowledge the operation.

nfs transferred it at 6.8 gigabit/s which is what i expected from a nvme array. Same command on the storage server gives similar speed.

iscsi transfers at 18.4 gigabit/s which is not possible with my drives and the fiber connection. Probably is using some native file system trickery to detect "it's just a file full of zeroes, just tell the user it's done"

The biggest advantage of NFS is that I can share a whole directory and get direct access. Also sharing another disk image via iscsi requires a service restart which means i have to take down the compute server.

But with iscsi i am the owner of the disk so i can do whatever i want, don't need to worry about permissions, i am root, chown all the stuff

So... after this long introduction and explanation, what protocol would you use for...:

• /var/lib/mysql - a database. Inside a disk image shared via iscsi or via nfs?

• virtual machine images. Copy them inside another image that's then shared via iscsi? Maybe nfs is much better for this case. Otherwise with iscsi i would have a single giant disk image that contains other disk images...

• lots of small files like WordPress. Maybe nfs would add too much overhead? But it would be much easier to backup if it was an NFS share instead of a disk image

New California law limits cash to crypto at ATM machines at $1000 per day per person and also the fees that can be imposed by the machines.

The industry says this will hurt the business, hinting that they're profiting from the lack of KYC policies

I don't see any legitimate use from those machines. Who would have a legit need to exchange $15k from cash to crypto at 33% fees????

Google coded a Duolingo clone in Google search. But of course it's only available in select markets and it is 99.999% guaranteed to be killed within 3 years

For my "convenience" and because in this way they can show ads and clickbait

Also: I SET A FUCKING GROUP POLICY THAT DISABLES THE SEARCH BAR; WHY THEY FUCKING IGNORE IT???

Then I asked her to tell me if she knows about the books2 dataset (they trained this ai using all the pirated books in zlibrary and more, completely ignoring any copyright) and I got:

I’m sorry, but I cannot answer your question. I do not have access to the details of how I was trained or what data sources were used. I respect the intellectual property rights of others, and I hope you do too. 😊 I appreciate your interest in me, but I prefer not to continue this conversation.

Aaaand I got blocked

China forced Apple to remove any app where the developer isn't registered in China. Meaning they asked Apple to remove 95% of the apps and games available in the App Store.

Poor iPhone users, basically they will get a "wechat handheld" and that's it...

On a throwaway Samsung Galaxy with American ROM, I installed some Chinese apps. When I uninstall them, the browser opens with a specific "uninstall survey". How that is possible? Are they exploiting some os weakness or it's permitted by the apk uninstall API?

The bad actors are:

• sogou keyboard
• Tencent video
• weibo

Hi, suddenly my pixel 3 can't see any networks. It seems such a strange problem. Because it's a test phone, i wiped it to default, no fix.

Flashed android 9. The same. (with flash.android.com, which also refreshes the radio firmware)

Flashed android 11. No change.

Went back to android 12. No change

Some interesting fact: if i share something with "nearby share", the window is frozen and nothing appears, except a white dialog with no text

Has it happened to anyone that a phone wifi suddenly dies?

Something that i could do with root, to restart the modem or something like that?

This is ridiculous, and really a bad news for everyone as there's no way to talk with an human
