I have coded things you people wouldn't believe...

notorandit··on Melbourne Train Control System is running on a hardware emulated PDP11
Maybe the PDP-11 is the one running the linked website.
notorandit··on A data table thousands of years old (2020)
DEBK is also tabular. And it's a perfect solution when you cannot (or don't want) delete or update older data. Just like when you write on clay tablets.

I wouldn't be surprised if we recover Sumerians example of DEBK tablets.

notorandit··on A data table thousands of years old (2020)
Usually we put "properties" as column headers while rows represent entities whose those properties are assigned or recorded.

It would be interesting to understand why it's not been the other way around or whether Sumerians used both orientations.

notorandit··on A data table thousands of years old (2020)
What it's not obvious it the amount of technical and cultural advancements Sumerians did. We don't know enough about them as their history has been mostly lost and only crumbles and leftovers can be recovered from the dust of the millennia. Besides a bunch of words still in use, in some form, in modern languages, the writing itself seems not to be the greatest invention, while bringing humanity from prehistory silence to history chatter.

I wouldn't be surprised if we found evidence of more technical and social advancements we have given for granted in the past thousand years.

notorandit··on BareMetal OS
Don't forget to contact AST in case you get some interest.
notorandit··on A visual proof that a^2 – b^2 = (a + b)(a – b)
Really? It even holds true for either a=0 or b=0.
notorandit··on A visual proof that a^2 – b^2 = (a + b)(a – b)
We need to introduce these simple demonstrations in math courses.
notorandit··on BareMetal OS
I would give Minix3 a try.
notorandit··on BareMetal OS
Os performance depends upon the overhead imposed over workloads. Being that a compilation, a computation or a communication task is a different topic.
notorandit··on C, Just in Time
New release is out!
notorandit··on A Brazilian CA trusted only by Microsoft has issued a certificate for google.com
It's not Microsoft being careless about CAs. That's been made on purpose by them to comply with some request in order to keep a slice of their market.
notorandit··on Ask HN: What would you preserve if the internet were to go down tomorrow?
The GNU project as a whole and Linux kernel. And maybe RISC-V stuff.
notorandit··on Vimium – The Hacker's Browser
Typpo
notorandit··on Cqwrteur's fork of Linux kernel, rename it to Cinux
IMPHO, I think that the removal of Russians contributors from the kernel contributor list is a big error.

Because it is all about politics. And the move let non-technical decisions step into this project.

Is it ok for you, Linus Torvalds, that politics can decide to ban also Chinese, Israeli, Iranian, European contributors? Or any non-USA developer?

Pesky developers or ones sneaking malicious code in need to be banned because their "contribs" would make the kernel worse (in a general sense).

Are Russian, Iranian or Israeliani devs making the kernel any better? Is the quality of their contribs in line with expectations?

Can those contributors harm or negatively affect the project?

Sorry, Linus. While still being a hero for me, that was a bad decision for what my opinion matters.

notorandit··on The Incredible Machine (1968) [video]
The real incredible thing is the "automatically generated subtitles". Try enabling them and watch the video again, Those need to be created by some AI, I guess.
notorandit··on Laptop Ports: Is USB-C only fine, or should I get HDMI,USB,Audio if I need them?
USB-C is a form factor. USB 3.2 and USB4 are ... protocol standards. Thundetbolt 3 and 4 are other things (only supported with Intel tech).

Be more specific, as USB4 w/ TB4 support can be ok for almost anything.

notorandit··on One Square Minesweeper
One square tetris Is highly needed here!
notorandit··on Vimium – The Hacker's Browser
Hacker's BrowserExtension.

Vimium is not a Bowser on its own. Not yet at least.

notorandit··on European govt air-gapped systems breached using custom malware
I would bet that those air-gapped systems are running some version of MS windows.
notorandit··on European govt air-gapped systems breached using custom malware
Exactly. Air-gapped means non data going in and out of systems. USB stick are acting as a cable.
notorandit··on Linux from Scratch
Nope. I never execute commands without understanding its meaning. Maybe you expect to complete a LFS installation in very little time. Which cannot be the case in general and in this very case in particular
notorandit··on MikroPhone: A privacy enhanced, simple and featured RISC-V mobile phone
> The security of the whole system is not compromised even though none of these modules is trusted, because all sensitive data is encrypted by the central MCU before sending it to a communication module.

No way. You need to decrypt that stuff before sending it to the communication modules (BT, WiFi, cellular, display) and you get them unencrypted from the same.

If the communication modules can decrypt the stream themselves, then eavesdropping will happen there inside.

notorandit··on MikroPhone: A privacy enhanced, simple and featured RISC-V mobile phone
Are all the needed software drivers open source? Or will this phone end up by using blobs, just like all other devices?
notorandit··on Terminal colours are tricky
Really?

I still think that white on black and green on black still work very well. At least for me in the past 40 years.

notorandit··on Legalizing Sports Gambling Was a Mistake
Very few political decisions can be said to be carved in stone.

The point is that reversing a popularly acclaimed law, while yes showing to be a mistake, leads to huge losses in political consensus at elections and an easy win to the other parties.

notorandit··on The lost language extensions of MetaWare's High C compiler (2023)
Yes, but the language itself is OK-ish besides a pre-processor that's too skinny.

Standardizing libraries is one thing I really favor. But force fitting them into the language itself maybe like over-engineering.

Let me have an example. qsort() and bsearch() are powerful but the call/return overhead is really unbearable. A (much) more powerful pre-processor which is really part of the language (and maybe syntax-aware) could help in creating templates that would generate solid code for either function with the bare minimum overhead.

I am not saying like C++ templates, but like C++ templates.

notorandit··on The lost language extensions of MetaWare's High C compiler (2023)
I for one think that we have lost a number of good opportunities to make C language a better and .ore powerful one.

IMHO what I would need with C is a powerful pre-processor like jinja2 and some symbol manipulation features too.

notorandit··on Btop adds initial Intel GPU support
I have been waiting for this feature for quite some time.

Of course this is not a goal but rather a starting line.

notorandit··on Atkinson Hyperlegible Font
The font itself is not enough for good readability.

So-called "UI/UX" designer are making a lot of fancy work to make things illegible. Contrast between background (aka "paper") and foreground (aka "ink") is going down and down. So, no matter the font of choice, text is becoming less readable (and less relevant) also because of color choices. While video and audio contents is getting more and more attention.

notorandit··on Michigan Micro Mote (M3) makes history as the smallest computer (2015)
No way to read the article any more ...

[UPDATE] Now it is back!
