I'm looking for an application (windows or maybe web) that can be used to combine images vertically and horizontally. I usually go with PhotoScape (screenshot) to for this but that's not free nor updated anymore. Important features for me are to be able to combine horizontally or vertically, set the number or rows or columns and have the ability to resize the final image.

Thank you.

The Banana Pi BPI-M7 single board computer is equipped with up to 32GB RAM and 128GB eMMC flash, and features an M.2 2280 socket for one NVMe SSD, three display interfaces (HDMI, USB-C, MIPI DSI), two camera connectors, dual 2.5GbE, WiFi 6 and Bluetooth 5.2, a few USB ports, and a 40-pin GPIO header for expansion.

Yet another win for Systemd.

I've notice that posts in this community tend to get deleted, even ones with multiple comments and/or useful information. Even worse is when they get posted again by some other user a few days later.

What's going on? What's the policy around here?

In this article, you will discover the ISO images that Debian offers and learn where and how to download them. I’ll also provide some useful tips on how to use Jigdo to archive the complete Debian repository into ISO images.

tr:dr; he says "x86 took over the server market" because it was the same architecture developers in companies had on their machines thus it made it very easy to develop applications on their machines to then ship to the servers.

Now this, among others he made, are very good points on how and why it is hard for ARM to get mainstream on the datacenter, however I also feel like he kind lost touch with reality on this one...

He's comparing two very different situations, more specifically eras. Developers aren't so tied anymore like they used to be to the underlaying hardware. The software development market evolved from C to very high language languages such as Javascript/Typescript and the majority of stuff developed is done or will be done in those languages thus the CPU architecture becomes irrelevant.

Obviously very big companies such as Google, Microsoft and Amazon are more than happy to pay the little "tax" to ensure Javascript runs fine on ARM than to pay the big bucks they pay for x86..

What are your thoughts?

Debian 12.1 (6.1.0-11-amd64) running LXD/LXC and on an unprivileged container setting security.idmap.isolated=true seems to fail to update the owner/group of the container's files.

Here is an example:

# lxc launch images:debian/12 debian
(...)

# lxc config get debian volatile.idmap.base
296608

# lxc stop debian
Error: The instance is already stopped

# lxc config set debian security.idmap.isolated true

# lxc config get debian security.idmap.isolated
true

# lxc start debian

Now if I list the files on the container volume I'll get they're all owned by the host root user:

# ls -la /mnt/NVME1/lxd/containers/debian/rootfs/
total 24
drwxr-xr-x 1 root   root  154 Sep  5 06:28 .
d--x------ 1 296608 root   78 Sep  5 15:59 ..
lrwxrwxrwx 1 root   root    7 Sep  5 06:25 bin -> usr/bin
drwxr-xr-x 1 root   root    0 Jul 14 17:00 boot
drwxr-xr-x 1 root   root    0 Sep  5 06:28 dev
drwxr-xr-x 1 root   root 1570 Sep  5 06:28 etc

I tried multiple versions of LXD/LXC. This happens with both 5.0.2 from apt as well with 4.0 and 5.17 (latest) from snap.

Interestingly enough I have another Debian 10 (4.19.0-25-amd64) running and older LXD 4 from snap and on that one things work as expected:

# ls -la /mnt/NVME1/lxd/containers/debian/rootfs/
total 0
drwxr-xr-x 1 1065536 1065536  138 Oct 29  2020 .
d--x------ 1 1065536 root      78 Oct 14  2020 ..
drwxr-xr-x 1 1065536 1065536 1328 Jul 24 19:07 bin
drwxr-xr-x 1 1065536 1065536    0 Sep 19  2020 boot
drwxr-xr-x 1 1065536 1065536    0 Oct 14  2020 dev
drwxr-xr-x 1 1065536 1065536 1716 Jul 24 19:08 etc

As you can see on this systems all the files are owned by 1065536:1065536.

Update:

I tried to probe around the maps with lxc config show debian in both machines and I saw this:

Machine running Debian 10:

security.idmap.isolated: "true"

volatile.last_state.idmap: '[]'

Why didn't it populate volatile.last_state.idmap: '[]'?

How can I fix it? Thank you.

Hello,

There's this website https://weather.ambient-mixer.com/the-perfect-storm that has a nice mixer of background sounds / ambient music.

I would like to know if it's possible to somehow possible to rip the player and all the music it allows on the channel mixers to use offline.

The same question also applies to those:

Thank you.

Some years ago, before LEDs were a thing, I bought an Ultrafire WF-500 Flashlight that features a Xeon light bulb. As you might imagine the bulb reached its lifetime and burned away.

Now a replacement bulb is available here https://www.ebay.com/itm/321916301663 the thing is that it will cost me 35€ and for that price I could just buy a new LED flashlight.

Now I was considering trying to adapt a generic LED bulb like this one here https://www.aliexpress.com/item/1005002419159094.html?mp=1.

Anyone else with this model of flashlight succeed at a similar mod? Any LED bulb recommendations? Or... is there any other source for the original bulb at a lower cost?

Hello,

I've been using Armbian on a bunch of ARM SCBs and they have a very nice MOTD on SSH login that shows CPU, RAM, Storage and networking infromation.

Is there anything similar for a regular x86 machine? I tried to grab the scripts from a NanoPi M4v2 board but had to change a ton of stuff to get it working on x86 and it isn't portable as AMD and Intel report temps differently. Or... does anyone know if their x86 version has it working and where to get?

Just for reference I'm talking about this: https://cdn.tcb13.com/2023/armbian-motd.jpg

Thank you.
