Questionable relationships between #ukpoliticalparties and #hindutva were around even before the #brexitreferendum in June 2016. Much of the #conservative campaign for the #london #mayor and #assembly relied on stirring up #antimuslim feeling among #hindu communities by implying that #SadiqKhan would literally strip gold ornaments off their womenfolk. And this particular campaign was in the first half of 2016! It did not pay off then but they have persevered with it since!

Machine Learners Guide to Real World - 🖥️ #LLMs for Compiler #Optimization: A Deep Dive
"The researchers presented a transformer model, trained from scratch to optimize #LLVM #assembly for code size. This model takes unoptimized assembly as input and suggests a list of compiler options to best optimize the program. It predicts instruction counts before and after optimization, and even the optimized code itself, enhancing its depth of understanding and optimization performance.
...
Contrary to the initial assumption that the paper would highlight the shortcomings of LLMs, it revealed that a sufficiently trained LLM could predict and directly apply the best optimizations to an input code, bypassing the need for a compiler altogether. This was a surprising revelation, showcasing the untapped potential of LLMs in code optimization."

🤔 Truthiness in C
➥ Daniel Xu
「 First I think it’s important to point out most casts in C are “free”. “Free” in the sense that the compiler changes its internal understanding of an expression. But in actual assembly nothing really changes – registers don’t have types. (NB: architecture dependent) 」

wooo. Odd/Even tester in #z80 #assembly, playing around with relative jumps and using flags.
It actually seems simpler to me than a traditional divide by 2 based algorithm? Using the trick of testing the last bit because that's enough in binary to tell. I imagine on this processor at least it would be much faster than divide by two based tests, since the z80 has no hardware division. I don't know if any assemblers or processors are smart enough to do the optimization to a bit shift trick used for divide by two. Compilers typically are, but the lower level tools might assume you have a specific reason it has to be division if you directly instruct it to do so.

One cool thing I discovered studying the DOS, is that you can create programs written in assembly using just "debug.exe" command.
And to those wondering what if we combine huffman and zx0; I ran the huffman output through zx0 and the results are better on the bottom end but slightly worse for general case in huffman. Still beats plain zx0 in all cases, though. Way too expensive to decode on a speccy, however.
Doing the zx0 first might compress even better, but I'm too lazy to test that.
On my quest of compressing floyd-steinberg dithered bitmaps; yes, huffman encoding beats zx0. But not so significantly that I'd be bothered to write a decoder in zx80 assembly.

I never wrote Assembly in my life, but tonight (for some reason) I thought of disassembling simple C code snippets with Ghidra. So, I started with a hello world and was very surprised to find a much more extensive and complex result compared to my original assembly (obtained with GCC).

How a CPU really works
Let’s go right inside a CPU and watch it execute code at the transistor level!
As a programmer I have often wondered exactly what the CPU is doing when I give it some code. Being a computer science teacher I know all about the fetch-execute cycle and what is supposed to be inside a CPU but what it actually does is glossed over.
Link to video here: https://youtu.be/n4e4KjcyeSE
So I set about finding out using the Visual6502 project’s simulation of the Zilog Z80.
This is not an emulator of the chip like you might be used to. This simulates the actual physical layout of the chip down to the wiring and transistors. It’s possible to step through the chip’s sequencing logic and watch parts of it switch on and off. It’s completely fascinating.
And once you figure out what’s going on, it’s possible to watch the CPU work.
This deep dive into the inner workings of the Z80 was inspired by one of my students asking me the innocent question of “how does a CPU work?” and then being persistent in wanting to know what it actually does.
I had no idea and I had to find out.
This video is the result.

Non vi ho detto che durante lo scorso inverno ho fatto questo corso di Gustavo Pezzi sulla piattaforma Udemy dove insegna a fare un gioco su Atari 2600. Molto istruttivo anche se non siete cresciuti a pane e #8bit come me. Se lo trovate in offerta ve lo consiglio. Oggi ci sono già molte risorse online per gli sviluppatori, ma avere tutto spiegato bene dall'inizio alla fine, con gli esempi e gli strumenti giusti, invoglia sicuramente di più a fare qualcosa. #atari2600 #assembly #gamedev

So with thanks to @fozztexx for reminding me about XCOPY; I have indeed managed to copy the #dos #assembly book examples disk to my my modern desktop. I’ll upload somewhere (probably @internetarchive) later on in case anyone else wants to see them; and I can load them onto an emulated system for more convenient use.
The Secret Life of C++: What Your #Compiler Doesn't Want You To Know
https://web.mit.edu/tibbetts/Public/inside-c/www/
“#CPP is filled with strange and wonderful features, with a few more added in C++11. We will explore in detail how these features are implemented under the covers, in terms of the #assembly #code generated.”
After finding I couldn’t download a copy of any #dos #assembly programming books from @internetarchive (they are only available to loan for whatever reason), I managed to track down a dead tree copy of this book (“Assembly Language for the PC” [3rd edition] - by John Socha & Peter Norton), which arrived in the mail today.
It even had the original floppy disk with it - containing all of the example code. But there my luck ran out. The disk is a 720k DD floppy - and my USB floppy disk drive (at least on my Mac, I’ve not tried any of my Linux boxes yet…) couldn’t read it - and a Win98 VM didn’t have any drivers for the USB drive. I do have an ancient DOS laptop which *was* able to read it (and confirmed it’s good), but short of rigging up some kind of USB serial to DB9 serial and running ZModem or some kind of serial file transfer tools - I don’t know how to get the files from that machine to anywhere I might want to archive the files.
Any ideas?

I'm sure Assembly won't hurt me like C++ did...
Oh, the video: https://youtu.be/9t-SPC7Tczc
It’s really odd… Just about every single book on #assembly programming for #DOS (both MS-DOS and IBM PC DOS - not that they’re really different things of course) that I can find on @internetarchive is restricted for borrowing only and not download. (And I’m talking about books that are from the 1980s here - not recent ones). I’ve found books for download on DOS that aren’t about assembly programming and assembly language programming books for systems than aren’t DOS - but not both. Anyone know why? #retrocomputers

@rml Absolutely, but you don't even need to go back in time that far. A lot of peeps (incl. me & friends) still grew up learning programming with pen & paper in the late 80s... Here're some scans from my teenage years (1988-1992ish)

20 years ago I was happy to demonstrate Pegasos #powerpc hardware at #Assembly 2003 #demoparty. As I recall the demo was arranged at very last minute and the devices only arrived on 2nd day of the event. The systems were set up to run the latest beta build of our #MorphOS operating system. Considering the ad-hoc nature of the whole deal it went surprisingly well in the end. Finnish #Amiga User Group (SAKU) was helping with much of the arrangements as I recall.
One of the best head-turner was the Pegasos system built into a microwave. This system had LCD screen behind the front glass, so at some point we got the epic idea of taking an interior shot of a real microwave oven in action and replacing the desktop background image with it. People would walk by, glance at the microwave and then their minds would get bent as the perspective did not change as expected. This resulted in a ton of people coming over asking about the system and taking photos.

I'm brand new here, so an #introduction is a good idea:
I'm a freelance tech writer / software developer / KM project manager based in Europe. Digitally, I was born in the 90s. So I grew up eating cyberpunk books, BBSs, home computers, hacking, then the first doses of Internet and the Web.
In the 90s and the first 00s I developed my (ahem) "philosophy": digital spaces are (can be, should be) autonomous zones where different cultures, and sub/counter-cultures, can thrive.
These are the years of the enshittification of Internet, but it can't rain forever (cit.) and I see the Fediverse as a new opportunity for some of us to recreate better and safer digital spaces.
That's the "vision". Than there's the daily life: I write code (awful, mostly), help companies in managing their knowledge bases, write technical documentation, sometimes write tech articles for (mostly unknown) business tech manazines.
In the spare time, I tinker with Linux, Risc-V boards and "old" languages like Forth, Assembly and C (but I'm a fan of Haskell too). I'm convinced that permacomputing and, maybe, collapse computing are our digital future. So, "back to basics" seems a good idea.
That's all, I guess. Nice to meet ya.

# NY designates state a ‘safe haven’ for trans youth, families and health providers
* #NewYork #Governor #KathyHochul #signed a #bill into #law on Sunday that #designates the #state as a #SafeHaven for #transgender #youth, #families, and #HealthCare #providers.
* The bill #prohibits state and #local #LawEnforcement from #cooperating with #investigations into families who seek #GenderAffirming #care for their #trans #children.
* It also #protects the #health #information of transgender people who seek care in New York, and it #prohibits #discrimination against transgender people in #employment, #housing, and #public #accommodations.
* The bill was passed in response to a record number of anti-LGBTQ+ bills being introduced nationwide.
Hochul said that the bill "sends a clear message that New York is a place where everyone is welcome, regardless of their gender identity."*
* The bill was passed by the New York State #Assembly and #Senate with #overwhelming #bipartisan #support.
* It is the first bill of its kind in the United States.
* The bill is being hailed by LGBTQ+ advocates as a major victory.
* However, some conservative groups have criticized the bill, arguing that it will harm children.

A good Python library and a set of tools for creating, reading, writing, inspecting, and manipulating Intel HEX files. It's handy also for processing the output of CP/M assemblers and compilers.
Though I suspect some of it is out of date, reading NASM's information for writing ELF libraries has taught me a lot about how ELF works. Like, I knew position independent code meant that you can't know your absolute location ahead of time, but hadn't really considered how that's implemented. (And C, thankfully, hides this all from me).
I put together a guide for c64 assembly coding to help others know where to start..

My impression is it's not as easy as the post suggests. For example, while data transfer and branching instructions are usually easy, most logical operations, shifts, and math/logic tricks are mind bending. But the post is a great starting point.
