[Guy looking happy:] Hey, there’s a Linux version of that program I like
[Guy looking disappointed:] Closed Source, no ARM support
What hardware are you using OP?
Raspberry Pi?

Discord app on Linux is like this.
Also SteamDiscord is just a website.
True
I really wish everyone would quit discord. Would make my life easier, as I’m not willing to give them a phone number.
I wish myself I can leave discord but I can’t
I used it for a while, having validated on a travel SIM. Deleted my number from discord today and… “You need to put in a phone number to validate.” Completely locked out without a number registered. I don’t think I’ll be paying for a spare burner SIM just to revalidate discord.
Oh yeahhh if they do this to me I will quit discord this will be my final strew(also if I get perm banned)
Oh my word if I read “today is your lucky day!” and am told to download yet another .deb file"…
I’ll probably download it and tolerate it because D&D is on there, but darn it if I won’t be mildly displeased about it! :) The real campaign is convincing my friends to use something else!
I use discord web nowadays so I don’t need to deal with that
My Little Rant on Risc V and Arm vs x86, because I have an opportunity to dump this here and get it off out of my system.
RISC systems will maybe perhaps take over market share from x86 in the mobile laptop space, but essentially there’s no point in anything else. If I remember correctly, RISC came before CISC in computing, and many old mainframes were RISC. But then people started thinking: “What if we can do multiple operations in a single instruction?” And therefore CISC was born and he did wonders for performance.
Yes, the reduced instructions are very nice for battery life. Who doesn’t like good battery life? People who like performance, that’s for sure. So if you run a programme that is programmed for CISC primarily, and then you just change the compiling target to a RISC system, then you will basically use the same battery life, but with worse performance than just using a CISC system, Since multiple clocks now need to do something that has happened in a single clock on CISC. I fully understand that having a monopoly on computing hardware is very bad. I don’t get the hype around arming normal computers because it will just shift the monopoly from one to another, the harm to innovation remains. Risc V is interesting because it would break the monopoly, but the problem is it uses a pushover license. So companies would reap all of the benefits for developing a proprietary risk system, and everyone who likes to compete is free to use the reduced, almost unusable base spec. I mean, compare the BSD kernel to the Linux kernel. It’s nowhere close. So with that being said, I think x86 in public domain would be the nicest thing to happen. Thank you for listening to my useless TED talk.
Edit: Thanks for the interesting replies, people! Time will tell what will have happened, so let’s find out together.
Just because a CISC will run multiple instructions in a single clock cycle, it doesn’t automatically make it faster. Complex instructions means complex decode logic, that makes the execution slower, even at the same clock cycle. A modern intel CPU has something like 20+ stages of pipelining, while ARM has 3-5 stages, that makes the execution more energy efficient and more powerful. Also superscalar RISC architectures exist, so RISC can also execute more instructions at a time, and in less time.
Lastly, modern x86_64 look like CISC, but are actually RISC under the hood, the single instruction is just a pseudo-instruction divided in multiple simpler instructions. I don’t believe thay makes it much more efficient.
RISC vs CISC doesn’t really matter. Both have heavily borrowed from each other. The big differences are design goals, x86 processors are targeting higher power processing with few very fast cores while Arm and Risc V mostly target embedded and low power computing or a huge number of smaller cores.
SIMD and CISC are not tied together. ARM has SIMD. RISC-V has vector extensions like old mainframes. they can both do SIMD and combined instructions jush fine. they just don’t have dedicated circuitry for them.

I know, but for most memes a single line of text is insufficient.
I’m on x86_64 and I think I probably will be until I die because I don’t see the point of switching
x86_64 patents lapse sometime this year, btw
sadly, there are a lot of important newer x86 patents that are still years off, and new ones are added every few years, so the best you could do next year is a 20 year old chip.

Basic x86_64 in hardware and software emulation of extensions is a more viable path than full x86 emulation on ARM. What we don’t know if anybody is working on independent x86_64 CPUs.
Make Athlon II great again!
Battery life in a laptop?
Yeah it’s never really an issue for me. I just make sure to bring my charger with me if I’m out somewhere with my laptop. Most computing is done on my desktop though, I don’t use a laptop very much
Also, most laptops aren’t at the 100Wh battery ceiling — in 2025, it’s exasperatingly difficult to find a non-gaming laptop that has a 100 (or 99) Wh battery.
You can use a USB powerstation with USB PD. The computer won’t know about its remaining charge on any powerstation that I’m aware of, but that’ll let you functionally untether for as long as you want, as long as you’re willing to carry the powerstation, plug it in when the internal battery gets low, and remember to charge it.
I keep a small 100Wh USB powerstation in my backpack, and a larger powerstation in the car.
Here’s an 1070Wh powerstation:
https://www.amazon.com/Jackery-Explorer-Portable-Generator-Emergency/dp/B0D7PPG25F/
This is considerably larger (and comes with a lot more electronics), but also ten times that amount of juice.
powertop
says that my laptop is currently drawing 10.6 watts as I’m sitting here. That thing could run my laptop at the current power usage for 4.2 days, assuming no idle screen powerdown or anything like that.Today, though, Linux doesn’t have the ability to have a USB power station and treat it as another BAT /sys/class/power_supply device, and there aren’t USB PD power stations that report their charge out there that I’m aware of. If you have a laptop running on USB PD power, it simply acts as if it’s connected to an infinite source of AC wall power.
Either you get app compatability or battery life.
Wait newer cpus got that too so I’m good with x86
My T470 still gets me 10hours. It’s enough
Yeah, that one would be huge, it’s pretty much the only thing I envy Mac users.
I already get 8-10 hours of active use out of my T14. Who wants to do more stuff for longer without a dedicated space for it?
I get sick of coffee shop stuff after like 3 hours.
The point will be when all the consumer/enthusiast hardware is ARM it will become the only reasonable option to buy.
Same also maybe with arm64 on my mobile phone
RISC-V :'>
isn’t there ways to enable compatibility for non-arm software in arm machines?
There hasn’t been much to my knowledge, but thanks to Asahi Linux’s efforts now Fedora ships out if the box with FEX as a solution as of last month (not sure compatibility, performance or ease of install for other distros, just reporting what I’ve heard) :
https://fedoramagazine.org/new-in-fedora-running-x86-programs-on-arm-systems/Yes, e.g. with Qemu or FEX.
How good is fex compared to qemu/KVM?
You might be thinking of Box64?
lol I usually just try my luck with yay’s “build anyway?”
