I'm using this implementation of EL. https://github.com/Jpn666/ctoolbox/blob/master/src/str2flt.c
If you want to use it make sure to compile that library using
--buildtype=release
to get better performance.
>>
>>106998580
1000 thanks anon
i know theres some (glaring) inefficiencies in my code, i am curious how far i could push it, and how it compares with an exemplary implementation
('bc it is, even my thing is only ~40-60 cycles, with the EL algo still faster than that. i estimated by ~25% now, but im gonna check properly, now i have the code)
>>
>>106998580
>>106998675
btw
i tought about the cost of simd today
and i went after what i thought was one of the larger performance hogs of the code
to see if the horizontal addition of 4 floats wouldnt be faster than the variety of intrinsics that i use in lieu of that

turns out that simple modification increased execution time by fukken 30%
and i still wrote it with the parentheses and shit to make sure the compiler will understand a way to compute that with optimal dependency (for ilp reasons)
nah.
changing from the spaghetti into human readable form increased the runtime by 30%
from 21s/1B iterations to 27.7. (i assume 3gigs speed bc ryzen 3600 that gives 60 cycles. not 40. indulge me im baked)

also curious fact:
fastest scenario for me runs in 19 secs
and thats half the memory ops
so im probably bumping my head against the latencies of simd
i already have a suspect in my code
the fukken additional blocks
but it think if i remove everything i can be using more than 16 vector registers at certain points and that means offloading shit to the stack
which is gonna tank performance i think
its 60 cycles. 4 cycles for a read and 4 cycles for a write and thats 13% of the runtime of added latency which may or may not be optimized away by the cpu
but then the compiler might/should do a better job at linking everything together

im not gonna code it today, but i think my intern tier use of blocks makes my stuff way slower than it should be
possibly fences which prevent out of order, which in turn influences latencies
certainly the fact that i pass everything through eax, which happens because i trusted a very bad source- everything is passed by value
although that may be because i force the behaviour with my blocks

>>106998782
>to see if the horizontal addition of 4 floats wouldnt be faster
I did the same for the multiplication of a 4x4 matrix by a vector, in row order. Using it made the function a lot of shorter.

quality across the board, design, sound, mounting options, the board actually being custom. you don’t have to dump $300+ on a sonnet to outcompete keychron though, literally any custom board will do that. sonnets are just popular enough to be a long term in stock option which is part of the reason they’re like $300+. you could get a neo75 cu instead. keychron sucks

Just accidentally put my google pixel through the washing machine like an absolute retard. Now it randomly turns off, gets hot quickly, and the sound is horrendous. For whatever reason, I can't quickly get access to silica packets in my country. I have to wait until Sunday. I've shut it off for now because I think it's just going to cause more damage if it's on.

I'm totally fucked, right?

Silica won't help, it needs to be disassembled and dried. Water leaves minerals behind and those conduct electricity, the mainboard will need some sort of cleaning to remove those.

Why do people use laptops instead of desktops? Muh portability, but where do you even go with your laptop? It's inappropriate to take it with you in social situations (not that any of you have any) and inconvenient enough to take out as it provides no use case for lugging it.

The Jelly Star is generally considered a good phone by the people who own it. The most common complaints would be the screen being easy to break and poor drop resistance but if you're a careful owner it's probably not bad if you're the niche it appeals to. A lot of people think the LEDs on the back are a gimmick and not worth the extra case bulk. The Jelly Max is mostly disliked for its questionable use case. The thing is not much smaller than a regular smartphone to be considered "compact", and it's thick as fuck too, so it basically feels not much dissimilar in your pocket. I think a lot of people would have said that a half inch to an inch more real estate would have been the perfect size for the next Jelly iteration but they went and made it 2 inches bigger which, I guess maybe wouldn't have been a dealbreaker if they could have kept it thin and light, but they didn't.

>Pixel 10 Pro Fold , case suggestions
Why the FUCK are so many of the cases lacking any sort of protection for the hinge? What kind of stupidity is this? Not to mention that many of them are expensive as fuck regardless, and/or don't ship until November for some god awful reason. Anyone have good suggestions for cases that have some hinge protection?

I've been thinking that the DBrand case may be the best option, but it doesn't ship until Nov. Worse, for some stupid reason Dbrand only has one model for the Fold, the "Grip" case; I wish they'd offer the Ghost 2.0 model for the Fold as it exists for the rest of the Pixel 10 lineup, but the Grip case is a decent alternative. It also works alongside their Prism 2.0 screen protector (version made for cases), which I am curious how it stacks up to other screen protectors. I'm also pondering one of those Ghostek alternatives, as they seem to be decent potential cases and are available reasonably fast, but not sure about the quality especially given the price and if they'll be compatible with a screen protector. I've used Spigen cases in the past but apparently one of them for the Fold seems to both lack hinge protection and apparently isn't very good quality from some Amazon reviews so we'll see. Any other suggestions for either cases or glass screen protectors?

i make 120k USD per year in USA midwest. if that's poor then OK i'm poor. but i keep $3500/mo after tax after bills (including mortgage). $3500 per month kept for myself to do whatever. i could pay the 10k in under three months. but why would i. i keep 10k and pay 800 out of the surplus 3500 per month. why throw 10k at it immediately??? 0% APR means i can do 800/mo and make money with the rest invested.... not a hard math equation, but seems tough for you. i hope you stop being retarded ASAP for your own sake.

Good to know people are still making progress in this area. OpenBSD is very well-designed and the only thing holding it back for desktop users is somewhat poor performance + TRIM

You lintards have been bullied so hard by winchads that you’re using all of the insults they pile on you to the BSD guys.
>>
>>106996834
Yep. Have for years. Nothing ever really changes in a user-facing way. They make improvements to the system but over time once you set shit up the way you like it, nothing will suddenly change and fuck you over which is common with Linux in my deep experience.

>>106996908
TRIM hasn't been needed in like 15+ years, all the drives do it themselves now. Some file system improvements happened when they switched to a 64-bit FFS of their own make. You have to obviously reformat for that to help you. Many network features were unlocked. The thing they want to achieve is doing this and all else CORRECTLY. If it's slower than Linux, it can be acceptable if the implementation is more correct.

BSD types are big into that. Berkeley took to Unix really well but they discovered the AT&T code was absolute horse shit in most places. The original Unix guys being firm believers in getting something done 90% of the way and then moving on. It allowed them to very rapidly develop the system but of course it was buggy and slow so short cuts were taken. Berkeley guys got ahold of it and rewrote every single part of the system with an eye to portability and correctness. It was slower than SysV by default but as the license was permissive companies started using it and would customize it for their hardware.

Culture difference.

Good reminder that accurate =/= good. It's possible that people could hear a difference but they just liked the sound of the cheaper one better. The 500k system might have been a more accurate reproduction of the sound, but if the cheaper one is particularly bassy and the headphones are lacking in bass, it's gonna get picked
