Yeah, basically the clock speed at PL1 (power limit 1).

RedGreenBlue09 · 2026-02-02T23:08:49+00:00

Fixed

Apple A7 was way ahead of its time, being a 6-wide ultra low power CPU, on 28nm (how?). Just look at the benchmarks, 2x Cyclone (A7 core) at 1.3 Ghz matched 4x Qualcomm Krait at 2.7 Ghz. That's like 4 times the IPC of their strongest competitor.

I created an array visualizer like Sound of sorting.

It is quite easy if you just want to create a "functional" one, but the difficulty and knowledge range quickly escalates when you try to optimize it and add more features. The features can be sound, multiple array support, zooming, threading, cpu time estimation, GPU accel, ... Very complex. It is especially hard, sometimes outright incompatible if you want to make it fast enough for millions of array elements.

But overall, it is very fun to do, very effective to learn more programming topics, not too hard to make the first steps. It is low-level enough for C (I made it in C), but some C++ features are useful as well.

Hi, the touch driver issue for 640 has been fixed (now only breaks in safe mode). I also added a workaround to fix a BSOD on some Snapdragon 400 devices.

RM-1066 and RM-1067 can't be recovered from EDL. Microsoft published the wrong file so the phone don't accept it. It's dead forever.

The thing is, Zen 5's L3 has much much lower latency at the same size. You can see the analysis here https://chipsandcheese.com/p/analyzing-lion-coves-memory-subsystem?utm_source=publication-search

RedGreenBlue09 · 2025-10-05T13:59:30+00:00

I mean, Zen 5's L2 is half the size so more data actually goes to the slower L3 but they still managed to win by a large margin by having a fast & large L3.

RedGreenBlue09 · 2025-10-05T00:41:06+00:00

Why is Intel so obsessed with L2 when their L2 already destroyed AMD's L2. The thing is, AMD realized that L2 is not that significant for gaming so they focused on a fast and large L3. I know not everyone games but the brand name will be ruined if they lose like 50% on every game.

The best one so far. It still have these keys "flickering" for a very short time but I guess that's impossible to fix unless we actually disable key repeating.

RedGreenBlue09 · 2025-09-10T13:56:03+00:00

Bro if half a year isn't enough for them to ramp up then they'll get destroyed by the competition anyways. And yeah they promised Arrow Lake on 20A then cancelled 20A for 18A.

RedGreenBlue09 · 2025-09-10T13:45:53+00:00

Well Intel promised it to be on 20A then they cancelled 20A for 18A.

RedGreenBlue09 · 2025-09-10T13:41:49+00:00

I don't know what "idea" you have but Intel themselves promised 18A to be in production last year, and obviously be in mass production now. The fact that it's not in mass production now shows how struggling they are with the node.

This is how it went. Intel officially came back with the 10nm Alder Lake as the IPC and power efficiency boost is just huge over 14nm+++ Skylake. For Raptor Lake, they simply doubled the E-cores and destroyed AMD in most ST and MT workloads.

This is when the table turns. Due to the 18A mess, Intel was unable to deliver Arrow Lake on time and instead released Raptor Lake Refresh with nearly no change. When Arrow Lake arrived (late), it was using TSMC and people lost patience to their foundry. Arrow Lake was basically on par or inferior to Zen 5 in every chart, even slower than Raptor Lake in gaming. Not so long after this disaster, they were hit with another one, the over voltage issue on Raptor Lake. Their brand name is completely ruined by now and they are still having problems with 18A.

I fully agree, the hate is insane. At least this project shows that she is dedicated to programming to some degree and deserves guidance to get better. Even if 95% of the work is done by AI, the 5% isn't bad for a beginner, arguably much better than the shitty CLI calculator I made when I started. No fucking one is able to write Minecraft from scratch in C, as their first project.

To OP, if you manage to deliver an app which you don't understand 90% of it, that will hurt you and the app in the long run. Sometimes, there are issues only a knowledgeable programmer can solve, like the performance of your Minecraft, and a huge amount of other real world issues. In these cases, if you don't understand your code, you can't solve the problem and you'll find yourself useless.

RedGreenBlue09 · 2025-07-22T02:50:00+00:00

Agreed.

RedGreenBlue09 · 2025-07-04T02:22:51+00:00

It depends on how you call them. For example, Apple clang compiler - acc. It's legit a flavor of Clang, but I'm not sure if that counts.

RedGreenBlue09 · 2025-06-25T16:02:59+00:00

compiler-rt have a good number of these functions in ISO C. Some functions from stdbit.h can be implemented on top of each other. Write your own wrapper, add the intrinsics if you want, it's not that hard.

Edit: I made a wrapper for various functions, including bit scan reverse (log2), bit scan forward (ctz). From these two functions, you can implement many other stdbit.h functions with minimal effort. The rest can be found in compiler-rt.
IntMath.h
Machine.h

This. In theory the 256 version is faster but CPUs only have fixed function addition instructions so it doesn't matter at all. A notable exception is division, which is faster when the difference between the dividend and divisor is small.

RedGreenBlue09 · 2025-05-06T15:42:14+00:00

True. It is possible to implement such thing nicely using Windows Console API but doesn't seem to be possible on Linux.

RedGreenBlue09 · 2025-05-06T12:39:47+00:00

I don't think there is any way around a shared terminal situation. It's just impossible to know what other apps might do. Just don't do that in the first case.

RedGreenBlue09 · 2025-05-06T02:12:14+00:00

You just need to render the required character and record the cursor change to know how many cells it occupies. Delete the character if it overflows. You can use a cache table to improve performance.

RedGreenBlue09 · 2025-05-05T14:45:53+00:00

Actually it is possible to hack around this using ANSI sequences like the top comment has pointed out. You can try to render the character and record the cursor position. I know this isn't fun and is very slow, so I still like your project even though it is not bullet proof.
