  • The issue isn’t emissions, it’s costs. Sadly we don’t live in a dream world, and everything has a cost.

    Even running excess production into hydrogen production has costs (transport, storage, infrastructure…).

    The current (not taking in consideration the new tech currently in testing) beeing highly ineficient creates many cost issues.

    Less effieicnt means that more power needs to be used to get that amount of hydrogen, reducing the gains on electricity surplus.

    The storage beeing ineficient means a higher running cost, more space used, less of that space…

    The transport beeing ineficient also increases the running costs, but also the emissions if the transport uses fossil fuel. Of it uses hydrogen, well it increases the running cost even more. That expensive produced hydrogen is used for transport…

    The electricity production from hydrogen being ineficient increases the used hydrogen to get the same energy amount, which then increases the costs because more of that expensive hydrogen has to be used.

    So taking all this into account, being “clean” doesn’t necessarily make it is viable compared to other storage or energy production tech.

    The costs have to be taken in account because resources don’t appear magically.

    Mining Uranium has a cost. Buying it from abroad has a cost, paying people to maintain all that has a cost…



  • Well the issue with renewable power like wind and solar, is that they are not stable.

    Having a battery in order to store the energy and release it when the demand is higher than production is one part of the solution.

    But what happens when there wasn’t enough solar and wind to replenish the batteries if those batteries aren’t enough for the demand? Power shortages, which are pretty bad to get.

    One of the solutions to this is natural gas for a simple reason : it’s very fast to start generating power or to stop. It’s also not very expensive, at least when there isn’t a war… The co2 equivalent emissions aren’t as high as coal either.

    Nuclear power on the other hand is very hard to stop. Having a surplus of power on the grid is also very bad. Some of it could be used to recharge the batteries, but there would be some loss at some point.



  • I finished Laika : Aged through blood. An indie metroidvania / 2d bike shooter / bullet time.

    https://store.steampowered.com/app/1796220/Laika_Aged_Through_Blood/

    It’s the story of a mother in a post-apocalyptic environment having to care for her daughter and village while doing the war outside.

    Everything, art, music, is a masterpiece. The music is just extremely good.

    Outside of special zones, there are 20 you have to find, and it cycles between them. All 20 are voiced, with words or humming.

    The story is good, and is extremely anti-war.

    The gameplay feels amazing. It can be hard at first, but I quickly learned how to control the bike and and to do backflips and frontflips at the right time to reload guns and the pary.

    The main character laika is one-shot, but the game isn’t very punishing. The respawn points aren’t too far away from each other, and they are optional. When you die, you loose a pouch with the currency, and can get it back.

    There are some little issues with the game tho. The ending seems to be a bit rushed. The ending boss isn’t that difficult, and there were some cuts it seems.

    But overall these little issues aren’t that bad, and the game is still amazing for an indie.

    And i can say that it is, damn amazing!

    There are some little issues with the game tho. It doesn’t tell that combo rewards more currency from enemies (it’s a timed combo, sho shooting will either increase or refresh the combo, and shooting flying bodies increases the combo up to 2 more times). The ending seems to also be a bit rushed. The ending boss isn’t that difficult, and there were some cuts it seems.

    • Mint = the desktop is closer to windows look.
    • Pop os = the desktop is closer to mac look. With extensions and settings with those, it can be even closer.

    However keep in mind that Pop OS is developing their own desktop to get away from gnome (the name of the desktop environment(DE) (the bunch of apps and tools making the desktop and settings work)).

    That new DE will most likely not be compatible with gnome extensions. And I don’t know how it will look.

    For functionality, both work pretty well.

    • Pop os has 2 ISO : one which includes the nvidia driver, and another without the Nvidia driver, should be easy to download the right one.

    • Mint I don’t remember exactly how it works, but it should be easy enough to download and install the proprietary nvidia driver, either through a driver tool, or through the store.

    • Pop os has a gnome extension which allow you to switch from integrated gpu / hybrid / nvidia “only” directly from the notification menu.

    • to switch in mint, you need to open the nvidia control panel.

    Both need a reboot or log out to switch gpu mode.

    (keep in mind, the Nvidia gpu consumes a lot more than the cpu integrated one. In hybrid, nvidia gpus canot be put to 0w sleep yet, so it will still consume some power).

    Both need a special argument for app launch or steam launch arguments to launch with the nvidia gpu if you set hybrid.

    For boot :

    • Pop os bypasses grub (a Linux boot menu), so to choose the os to boot from, you’ll have to either use your laptop’s boot menu or the bios priority.
    • Mint has a grub boot menu displayed each time. So if you choose mint as priority boot, you can at boot still choose windows (about 5-10 sec to use the arrows to boot into something else than mint).

    Disadvantage :

    • Pop OS still needs an additional app to be able to change all settings, including mouse acceleration (say thanks to gnome devs, theming has become harder to do for non gnome standard themes).
    • Mint : they only now made plans to develop their DE to support Wayland (a new window manager explained a bit further), and so you could have a bit less track pad fluidity (no 1to1 gestures … ). Tho as the DE used is cinnamon, there is less use of track pad gestures.

    About Wayland : it’s a “new” windows manager (what allows apps to be displayed, and how they interact with each other). It is a hopeful replacement for X11 (released in 198X, before Linux…) full of issues but still working well for what it has to do. Wayland wants to bring enhancements on security, gesture fluidity and many other things. However it is not yet fully developed and you shouldn’t really base your decision on it yet.

    For the rest. I don’t really remember other disadvantages as i don’t really use them anymore.




  • Well fedora isn’t really a beginner friendly distro. The community is much smaller, and there is a lot more outdated or bad advice circulating when searching an issue.

    When I installed fedora on my laptop some months ago, I wanted to switch the ffmpeg install and get codecs installed. Even fedora’s documentation was outdated.

    Only by searching and digging in some websites I found a command I had to do to make it world, in order to switch the ffmpeg version away from the open fedora version…

    Hey, for my recommendations keep in mind I did not use Linux as a main os for some time now. It is based on me following Linux channels and news, but also my past experience and installing it on my laptop and my brother’s laptop.

    Linux distros are different in the packages they choose to include for their environment, use and desktop. Some distros offer different desktop environments (which are different desktop softwares, with different handling of included apps, settings and theming).

    Depending on how well you know how to search online and not follow outdated advice, some different distros can be interesting :

    Beginner friendly for Linux :

    • Linux Mint (cinnamon desktop)
    • Pop OS (gnome desktop)
    • Ubuntu (gnome desktop) (maybe, but I’d rather choose Pop OS due to snap packages of Ubuntu beeing forced and having lower quality compared to apt and flatpak)

    All desktops can be themed. Tho cinnamon I don’t know how well it supports modifying the task bar.

    Gnome can have extensions to do things, show a bottom task bar, start button, start menu…

    For these 3 distros, the system package manager used (installer, app searcher) is apt-get (shortened to apt). It is a well k’ow package manager with plenty of tutorials online. All also include flatpak, which is a special package manager where apps Comme bundled with their own dependencies (software to make the main software work), and so reduce incompatibilities.

    Ubuntu as a package manager called snap installed by default, it has the same objective as flatpak, but it is closed source, and already had issues with malware spreading through it.

    Obviously all 3 package managers can have issues, as community is there to check the apps, but it may not always be safe. The safest package source is still the system one apt as packages are checked by the people maintaining the main distro repo. But many flastpaks and snaps are safe. (tho they can have some theming issues).

    All of these 3 include a GUI store where you can search and install apps.

    Another great distro which can work for beginner or advanced

    • Fedora desktop (gnome) (It is also available with the kde desktop). Tho this one has a smaller community, and so there is less useful help online, and there may be more out of date advice you would have to navigate through.

    Fedora has a pretty good documentation, but even that one seems to be a bit out of date on some things.

    If you have an nvidia driver, this one doesn’t have nvidia proprietary drivers installed by default nor help at the beginning on automatically installing them. You have to enable at install (or after in the store settings) the nvidia closed repo and install the nvidia driver from the store.

    Kde as a desktop is pretty great, tho it can be overwhelming with all it’s settings and options available to the user.

    Gnome tho still requires an app to be able to control hidden settings like mouse acceleration and some other settings.

    I wouldn’t recommend other distros for beginner or someone who just wants to easy setup and work.

    Debian is pretty stable even in its “testing” branch (Debian stable = old bur rock solid, not recommended for gaming. Testing = newish, still not breaking. Unstable = unstable) needs to have a manual install or help through someone’s script.

    Manajaro is a mess. On some devices it will work, on other it will just desintegrate after some months.

    Or the communities are so small that packages may easily pass testing and break.




  • Unreal engine is pretty bad for open maps. It generates a lot of cpu usage when changing zones. And heavy textures and other heavy elements don’t enhance the experience.

    The vram, I’m not sure what your questions is about.

    The vram is special ram (much higher bandwidth, but slightly higher latency than cpu ram, also supports special extra things) included on the board of the graphics card.

    It is necessary because it stores textures and others game elements the graphics card needs to operate the game (shadow info,…). The elements are loaded into vram, from the very slow (in comparison) drive (even nvme 5.0 ssds are extra slow compared to vram or ram) to allow the gpu to process whatever it has to do. Background tasks, windows, the desktop… Also use vram to be able to have the app windows and desktop displayed, so the total available for the game can vary.

    If there isn’t enough vram, there can be multiple things happening (I’m talking about textures but vram includes others things too) :

    • Resizable bar ( or SAM on amd) is not enabled : the gpu will not be able to load all the textures, so it would either have missing textures, or lag a lot due to texture swapping. The textures can also take a lot of time to load instead of completely missing depending on the game optimisation, due to swapping with previous textures. The game can even crash.

    • Resizable bar is enabled : it is possible with this pci-e configuration for the gpu to access system memory. So in some cases, textures may spill into system memory (cpu ram), which isn’t great either, because system memory has a way higher latency to the gpu (it has to go through the cpu, pci-e slot…), and way lower bandwidth. And so generates lots of lag.

    If a game is well optimized, the lower the settings are the lower vram usage there is. Some games however did not have such great optimisation. Vram usage mostly depends on the texture quality and resolution. (increasing the texture quality will use a very few/negligible amount of extra gpu power, but increase the vram usage).

    There is also a baseline the devs may put for optimisation. The less vram there is, the less the textures can have data available to use. So the more compromises have to be done, with less and less quality. So fixing a baseline quality depending on the current most used vram capacity is not that bad. Tho it does have issues for people having less available.
