According to a book I am reading, diet science currently agrees that there is one way to loose weight: A calorie deficit.

For example, if I need 2000 kcal a day and eat only 1500 kcal a day, I will loose some weight over the next weeks/months.

To my understanding, calories here are totally interchangeable, if we are only concerned with loosing weight (and ignore nutrients etc).

Calories are basically measured by burning food and measuring how much energy was set free.

My question is: Why and how does it work so good and why are calories interchangeable?

In more detail: Why can we translate the burning of calories with fire to processing the calories in food with our digestion system so perfect? Why is there no difference (concerning weight loss), if I eat 1500 calories as pure sugar or eat them as pure protein (where I would assume the body needs more energy to break down the protein)?

Question is in the title: What is the supposed workflow for vanilla Gnome for keyboard users?

Is there any video/design documents which explain, how the workflow is supposed to be?

Assume, I have a full screen web browser on workspace 1. Now I want to have a terminal... I hit the super-key, type terminal, hit enter ... and then I have a terminal which does not start maximized on workspace 1, so I can either maximize the terminal and switch between the applications, arrange them side by side... or I can navigate to workspace 2, start the terminal there (the terminal will not start maximized again on an empty workspace 2) ... and switch between the two workspaces (AFAIK there are no hotkeys specified by default to navigate directly to a workspace)...

What I simply do not understand: Does the vanilla Gnome workflow expect you to use mouse and keyboard? Like hit super, use mouse to go to next workspace, type terminal, click to maximize terminal (or use super-up)?

It just seems like a lot of work/clicks/keys to achieve something simple. And to my understanding Gnome expects you to use basically every application with a full screen window anyway, so why does it not open a new application on the next free workspace full screen by default?

When using TMUX, it is easy to create a script, which opens TMUX, configures the screens/panes of TMUX and open/run programs.

I like this a lot.

My baseline would be something like, when I login, some applications are executed and their windows automatically placed on a virtual desktop.

For example:

• Open Firefox and put it on virtual desktop 1
• Open Terminal in fullscreen and put it on virtual desktop 2
• Open VSCode and put it on virtual desktop 3

Something like that is possible with sway, in the environment I am working, sway is not able to run XWayland applications w/o crashing.

Is there any way to have this functionality on Gnome, Mate, Xfce?

Even better would be something to open several windows and arrange them automatically for different work tasks/projects I am working on. Any ideas?

Edit: Solved! Thanks for the input. Auto Move Windows extension for Gnome solves my problem.

Shout out to the great Hungarian people! :-)

Hello, fellow Linux users!

My question is in the titel: What is a good approach to deploy docker images on a Raspberry Pi and run them?

To give you more context: The Raspberry Pi runs already an Apache server for letsencrypt and as a reverse proxy, and my home grown server should be deployed in a docker image.

To my understanding, one way to achieve this would be to push all sources over to the Raspberry Pi, build the docker image on the Raspberry Pi, give the docker image a 'latest' tag and use Systemd with Docker or Podman to execute the image.

My questions:

• Has anyone here had a similar problem but used a different approach to achieve this?
• Has anyone here automated this whole pipeline that in a perfect world, I just push updated sources to the Raspberry Pi, the new docker image gets build and Docker/Podman automatically pick up the new image?
• I would also be happy to be pointed at any available resources (websites/books) which explain how to do this.

At the moment I am using Raspbian 12 with a Raspberry Pi Zero 2 W and the whole setup works with home grown servers which are simply deployed as binaries and executed via systemd. My Docker knowledge is mostly from a developer perspective, so I know nearly nothing about deploying Docker on a production machine. (Which means, if there is a super obvious way to do this I might not even be aware this way exists.)

For one user account, I want to have some bash scripts, which of course would be under version control.

The obvious solution is just to put the scripts in a git repository and make ~/bin a symlink to the scripts directory.

Now, it seems on systemd systems ~/.local/bin is supposedly the directory for user scripts.

My question, is mostly, what are the tradeoffs between using ~/bin and ~/.local/bin as directory for my own bash scripts?

One simple scenario I can come up with are 3rd party programs which might modify ~/.local/bin and put their own scripts/starters there, similar to 3rd party applications which put their *.desktop files in ~/.local/applications.

Any advice on this? Is ~/.local/bin safe to use for my scripts or should I stick to the classic ~/bin? Anyone has a better convention?

(Btw.: I am running Debian everywhere, so I do not worry about portability to non systemd Linux systems.)

Solved: Thanks a lot for all the feedback and answering my questions! I'll settle with having my bash scripts somewhere under ~/my_git_monorepo and linking them to ~/.local/bin to stick to the XDG standard.

Let me start with, that I am running Raspberry Pi servers since the first Raspberry Pi was released more than a decade ago. Only problems I ever had until now, where dying SD-Cards with the first generation of RPIs. Since them I only buy really big high quality SD-Cards and I have RPI(4) servers running 24/7 for years w/o any troubles.

For a new project, I am running a web service on a Raspberry Pi ZeroW2 with an Apache reverse proxy on the same machine. Memory usage, even under load, is a maximum of 100 MB. This RPIZW2 simply dies after a few days, and I have no idea how debug this problem.

More details of the RPIZW2:

• Uses Raspbian configured via Ansible to be an exact replica of my RPI(4), only Apache and a webservice were added
• Quality power supply (original RPI hardware) and literally plugged to the same electricity circuit as the RPI(4)
• The webapp is just a 'hello, world' with the current time and my internet connection is not fast enough to be DOSed
• Monitored memory usage etc. for several hours and found nothing out of the ordinary
• fail2bann is active and running
• SD-card has several unused GIGs of free space and is same brand/quality as the one in the RPI(4)

Anyone experienced something similar? Has anyone an idea how to approach debugging this problem?

I am not sure that there is a better place at Lemmy for this kind of question than here. I'll happily move this post to another place, if it is not appropriate here.

Just to be clear: My main point of sharing this article is about how detached the life of rich people is.

I do not at all agree that most of them are “Not evil, just disconnected”, I am pretty sure (and know some of the privileged), who are actively evil, know exactly what they are doing and just don't give a shit.

IMHO a very cool project/idea, worth being promoted!

MGLRU.

On my low RAM/CPU netbook it is a game changer; thanks to ZRAM the netbook is perfect for browsing the internet/light work. When running my backups (creates big tarballs) or Ansible though, my desktop/applications would freeze/stutter noticeably. Enabling MGLRU simply solved the problem of freezes/stuttering, it feels like magic and besides ZRAM, I don't know of any other lever with this massive impact on desktop performance.

Just wanted to share this, for other users with low RAM/CPU hardware. I would assume the observed difference is less dramatic, once 8GB of RAM are available, but I would love to hear about other experiences.

I would also love to hear/learn about other levers with high impact to tweak for low RAM/CPU desktop devices. Anything else to tweak under /sys /proc which has impact on performance?

Title is question, but to clarify my assumptions:

• Vaccination is a numbers game, and the odds are in your favor that the vaccination will protect you over you get a side effect or an allergic reaction/shock
• An infection like covid/flue can damage your body long term, not even speaking of long covid etc.
• To the best of my knowledge it has been shown that flue shoots lower the risk of dementia later in life, wouldn't it be a good enough guess that a covid shoot decreases risks for this too
• Even if we only assume a covid vaccination is highly to reduce your sick days for only this year, isn't it a rationale tradeoff to get vaccinated, just to avoid 1-2 weeks sick?
• Given the security of covid vaccinations, I feel like they have been scrutinized and tested extremely well and to the best of my knowledge it was checked that nothing of the vaccination remains in the body after a few weeks (for the argument that nobody knows the long term effects of RNA vaccination)

Again my question: Why doesn't the WHO or don't most countries recommend covid vaccinations for everyone? Are there any health/medical reasons? Are there financial reasons? Are there any countries/governments which recommend the covid vaccination for everyone and not only the 'vulnerable groups'?

Edit: Just to add, I am living in Germany and right now we have a big wave of children flue, where children even die in the hospitals and the children hospitals are near their limits. It seems common sense to just put flue/covid vaccination into every child/adult, to avoid situations like this.
