I like the theory that 42 was chosen because ASCII 42 is *, as in the wildcard character. It matches everything!

I could see someone tipping people like Foone who publish content primarily as stream of consciousness style Twitter threads.

Why not just sign the content with a digital signature?

You might have better luck sending SIGINT instead of SIGTERM using 'killall -INT ffmpeg' so that it exits cleanly.

This book is an excellent introduction to assembler design. I worked through it myself a while back and used the ideas to write my own assembler and loader for my calculator's embedded CPU.

I think it’s genius, but evil. Like you say, real email addresses have all been pwned so this is a way to test for bogus or typo’d email addresses.

What a way to ruin a wonderful thing! Abusing the haveibeenpawned service in this way has worried me enough that I’ve now gone and removed my data from the publicly searchable database. I’ll use the notification service instead.

Why not? Can a comparison not be made to writing source code and the output of a compiler?

>not through SMS, but through some other system that takes over the whole screen - not sure what it is

This sounds like it might be a so-called “flash” SMS. https://en.wikipedia.org/wiki/SMS#Flash_SMS

I can hear it without an AM radio! It's very clear but extremely quiet. My machine is muted and I'm trying to work out where in the world the audio is coming from. I wonder if it's just the speakers in this monitor picking up the signal. Or one of my switched mode power supplies that also sometimes whines very quietly in the background.

I'm not sure I'd go that far, but certainly one of the really nice things about Forth is that it's so easy to bootstrap up from just assembler into something usable.

Rachel's blog posts are brilliant for preparing for stuff like this. She's highlighted some great clues to look out for in the past, like seeing the constant 0x48545450 where it shouldn't be[1].

For our users we use Kerberos authentication with AD, rather than SSH keys. Once a user has a TGT on their desktop, ticket forwarding takes care of SSH SSO from there.

The same TGT can also be used for other neat things like secure and transparently automounted homes and other directories via NFS4 or CIFS.

Not necessarily. When you live inside the wavefunction the outcomes of certain experiments very much look like a wavefunction collapse. MWI is a way to explain why that happens without having to have a special case where the universe has a completely different behaviour for just a moment in time.

You can formalise the mathematics of it using the concept of quantum decoherence.

My lockdown project has been hacking up my CFX-9850G calculator. So far I have physically removed the ROM of the calculator and replaced it with a new ROM (I was able to get old-stock chips from aliexpress) flashed with a patched version of the original OS that includes a new BASIC command to jump to a fixed location in RAM and start executing whatever is there. This means I can write and run arbitrary machine code in the calculator’s RAM by abusing the built in backup feature. The Hitachi CPU in the calculator is quite strange but by working with the little information I can find online [1] I have written an assembler and linker for creating compatible machine code from a custom assembly language. The resulting code runs much faster than in BASIC because it doesn’t have to be interpreted. Here [2] is a video of the calculator jumping into RAM and running a Game of Life program that I wrote when Conway died. I’m currently writing code to run the 3-colour display for a replacement Forth-like shell/OS with the aim to eventually get to the point where I can replace the calculator ROM completely with my own. Writing my own mathematical functions for a calculator is fun when (AFAIK) the CPU itself lacks even multiplication opcodes.

It’s less common now, but I do remember helping multiple people in the past who had installed malware masquerading as “PC Optimiser” software. Usually these would contain big green buttons labelled something like “Optimise system RAM” and show lists of many problems it was helpfully fixing for you.

Some users were utterly convinced that their machine was running faster than ever before, when in reality the malware did nothing other than begging for cash payments. Often the opposite by slowing down the machine with continuous pop-up advertisements and other nasties.

Imagine that you are standing on the equator of Earth, facing North. Now imagine a friend is also standing somewhere on the equator -- not too far away, but a fair distance -- also facing North. Now, if you both start walking you'll find that you begin to move closer together. The distance between you shrinks as you walk, until eventually you meet at the North Pole. The "force" that is pulling you together is like gravity in that it is caused by the curvature of the Earth's surface as you travel across it.

With gravity the curvature is intrinsic to space-time itself and is affected by mass. Generally more mass means more curvature. So if you sit two objects in space, at rest with respect to one-another (but still travelling forwards in time), you will find they are pulled together and eventually meet in the same way you and your friend were pulled together and met at the North Pole.

You might ask why mass affects the curvature of space-time? That I don't know the answer to.

There's an iOS app called Retrospecs that has some cool lo-fi filters.

I'm not sure that's true. I much prefer solving my 5x5x5 rather than my 4x4x4 because I always forget the algorithms for the extra parity that even cubes provide. I don't think I could solve a 6x6x6 with the 5x5x5 algorithms I know.

I recently played an Asterioids cabinet at a retro gaming convention.

The shots in particular are extremely bright. Perhaps the cathode ray sits there slightly longer than for the other lines so that it's brighter.

I have a lasting impression of just how different the screen looks from modern displays. The combination of high contrast, light bleeding and the long image persistence makes it so different to emulation.

I index from -N:N so that 0 is in the centre of my computational boxes.

Not as pretty as OPs but I made this little game: http://extigy.github.io/primes/

I didn't really think about game theory or anything. I just had an idea and wondered how it would play.

This is mental and I love it.

Don't you need an infinite map for that?

It's been edited and now says:

>Sublime Text is a great editor with a much lower learning curve than VIM or Emacs.

Oh man that would be so cool. I suppose if text based adventure games can "understand" meaning within text, there's no reason it couldn't be remodelled into a chat setting.

Thanks a lot. Disabled here too.

Nah, Google is just way OP.
