- Comment on Nuclear energy is more expensive than renewables, CSIRO report finds 10 months ago:
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 mean it is viable.
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…
- Comment on Nuclear energy is more expensive than renewables, CSIRO report finds 10 months ago:
It’s another solution, now there is also issues with costs. However with time the costs can be reduced.
For hydrogen based on this video : youtu.be/M0fnEsz4Ks0 there could be some hope for large hydrogen storage for a smaller cost (not used in cars tho, due to the weight).
Hydrogen production however is/was very ineficient. However there is also some hope for this youtu.be/m0d6iljzzEI
So with this, maybe it could be an interesting solution to store energy.
Tho I’m not sure how efficient it would be to produce energy from that stored hydrogen, and how efficient it could be for the entire hydrogen production/storing/electricity production chain.
- Comment on Nuclear energy is more expensive than renewables, CSIRO report finds 10 months ago:
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.
- Comment on Single-use e-cigarettes contain batteries that last hundreds of cycles despite being discarded 10 months ago:
There is a difference. Not sure how they ar made, but the chemical composition and possibly the design is different.
Trying to recharge a non rechargeable battery can risky and there is the possibility of leaking or explosion.

- Comment on Epic win: Jury decides Google has illegal monopoly in app store fight 11 months ago:
It’s something else. Here it’s US antitrust monopoly.
Google made deals with games and special contracts with other apps in order to kill competition.
- Comment on Epic Win against Google 11 months ago:
One of your questions don’t seem to be that based?
“shits on Linux gamers”, are you talking about the store not beeing available on linux? Meh already got heroic which is better.
Their easy anticheat is available through proton tho, it’s on the game dev to chose to enable it or not (and I understand why they don’t do it for fortnite : the Linux market is pretty small, but also because the game is so huge that hackers will not hesitate a bit to switch to Linux in order to hack with custom kernels).
- Comment on Avatar: Frontiers of Pandora - OpenCritic Review Thread 11 months ago:
Hmm, from the average and some reviews here and there, it’s sad the game is just mixed.
It’s the first to get out with fsr 3 frame gen working mostly well. Fsr upscalling working mostly well, which is very unexpected due to a lot of foliage.
Tho the ui protection to frame gen was implemented in a very shitty way (just a box without frame gen arrount it…).
- Comment on Alternatives for simplemobiletool gallery and calendar? 11 months ago:
This : github.com/SimpleMobileTools/…/241
As explained sold to ZippoApps.
From a reddit post reddit.com/…/simplemobiletools_was_sold_alternati…
There seems to already be a fork : github.com/FossifyX
Tho not sure how trusted it can be.
The reddit post also suggests some alternatives. The comments in that post also suggests more alternatives.
- Comment on Alternatives for simplemobiletool gallery and calendar? 11 months ago:
Hey on android? Didn’t know simplemobiletools was sold. I use their qr scanner. Should be fine if updates are disabled from play store and only f-droid versions are used.
But for alternatives :
For a gallery app, I find Aves to look pretty good and has many great features github.com/deckerst/aves
If you need gallery (still not that great yet) & backup : ente gallery (there are other apps too) ente.io
For a calendar no idea.
- Comment on 'Great' games I didn't play this year due to requirements 11 months ago:
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.

- Comment on 'Great' games I didn't play this year due to requirements 11 months ago:
A big issue with recent games is Vram usage (the gpu has vram). If you don’t have enough vram the game will stutter. At the moment where there isn’t enough vram, even a tiny bit not enough, the game will stutter.
Another issue is also ram and cpu utilisation which in some games is pretty extreme.
Othrt issue can be very heavy graphics and badly optimized lower settings.
Some games also have transition stutter, where you change zone. It will try to load the jew zone and unload the precedent one. But it uses cpu power and requires a fast ssd depending on the size of what has to be loaded.

Another article, much better and presents in more detail that Olvid was audited on an older version and chosen because it was French and they applied for it (French) numerama.com/…/1575168-pourquoi-les-ministres-von…
- Comment on The French government doesn't consider WhatsApp, signal or telegram secure enough, replaced by Olvid (Google translate link in post text) 11 months ago:
Well let’s give some counter examples in the softwares I mentioned :
WhatsApp closed : Owned by Facebook. Well Facebook had multiple data leaks, privacy violations and nothing substantial was done about it. Definitely not trustable (also zero days are getting sold on the black market for WhatsApp (techcrunch.com/…/zero-days-for-hacking-whatsapp-a… ).
Telegram closed : not end to end encrypted. Russian app. Not trustable.
Signal open (servers I don’t know): well this one is e to e encrypted. Open source, maybe could be trusted. Seems to have passed some security audits (community.signalusers.org/t/…/13243), tho it’s based in the US and uses servers, maybe the US may have super computers capable of decrypting such communications. However is signal has switched their encryption to quantum computer resistance it may be too hard even for a state actor.
Olvid (open, servers I don’t know) : is French and why not use a local messaging app witch also is very secure and open source.
Notice how closed source is untrusted here. The economic activity of the tool changes how trustable it is. Military équipement has a huge and strict budget, it has to be secure.
Communication apps are user first. So they do what they can get away with, and that is very true for Facebook.

That is a European proposition, and not French at all. France can stand for or against that.

Because lots of people aren’t smart enough to make the link with a factory.
But the non smart people see smoke or steam and they think pollution.

- Comment on Great! I like getting tracked by 766 third parties! thanks Outlook 11 months ago:
Sending the entire email content to their cloud isn’t that good.
However an advantage to doing so is to be able to use push notifications on the app without having to poll continuously the email address from the device. Which in return reduces the battery usage compared to constant polling.
However, they could have done something like spark mail, only get the email subject, sender and a little bit of the content to put into the noficiation then delete after the push notificdation has been sent.

- Comment on Thermal Transistors Handle Heat With No Moving PartsThe technology offers a new way to cool down chips quickly 1 year ago:
This article is so much better than what was posted 2 weeks ago (lemmy.nz/post/2974266).
Now I do understand it better, tho still not perfectly.
So it can be used to manage hot spots in chips and semiconductors.
If you don’t know why it matters, in one of these 2 videos (I don’t remember which one) Der8auer discusses with an intel engineer the challenges of designing a chip, where to put the thermal probe and why some parts are designed like that :
Basically : the heat travels through the chip at different rates depending on the material distance… And finding the hot spot is very challenging, also because it is generated in the cpu cores, which may not have room for a thermal probe.
So having better cooling where it matters can be a benefit for chip cooling and efficiency.
Now I don’t know if this tech can evolve into something which can be used for this.

What this? The user to user or device encryption? From the article, it seems that they stand also against device scanning.
- Comment on Key EU parliament comitee took stance towards protecting end-to-end encryption, and no device scanning. A possible win for privacy 1 year ago:
End to end encryption means user to user. Not a local storage… It’s just an encrypted storage, there is no end.
- Comment on Where to store OTP tokens 1 year ago:
Well, the whole point of otp tokens/2fa, is to have a second login confirmation. Mostly on another device, like a phone.
Now maybe if you store your 2fa way on the same device, but locked away with a strong password, it may work, and could be safe enough.
But if it’s the same password as your device or another account, it isn’t that safe.
