Simple 8-bit Assembler Simulator in Javascript

Simple 8-bit Assembler Simulator in Javascript

Source: schweigi.github.io

One of many simple CPU simulators. I'm teaching a course in Operating Systems and I've been looking for a really simple and clear visual simulator for a CPU. This one is the best one yet. But I would like a better one. This one is missing any kind of support for IO or System calls or something like that. But it's usable.

It seems that no one and nowhere is safe from hackers: "Threat analysts at AquaSec have experimented with the security of VSCode Marketplace and found that it's surprisingly easy to upload malicious extensions from accounts that appear verified on the platform."

Thanks to the DALL·E 2, we finally have a very nice graphic representation of the feelings of a Docker container inside a macOS environment, I will try with this article to make this poor container safe to the coast. TL;DR Link to heading At the time of writing, the only viable option to have a decent performance and a good DX are: VirtioFS to share the filesystem (Docker Desktop, Rancher Desktop, Colima) - There are still some issues.

Opinion | The Alt-Right Manipulated My Comic. Then A.I. Claimed It.

Another interesting continuation of the debate on the impact of chatGPT and Stable diffusion and the other newest ai based creative genetors. I think these new tools are a big thing, a game changer. Will it bring on a series of new and common ways tomdigitslly sign content produced? This idea sounds ok but there are a lot of issues with bringing it about. Will it bring out a new, singular, ethical concept sitting along side “original work” and “plagiarism”? Here is the author: “My drawings are a reflection of my soul. What happens when artificial intelligence — and anyone with access to it — can replicate them?”

Regexp Preprocessor

Regexp Preprocessor

Source: pomsky-lang.org

Regexp Preprocessor URL: https://pomsky-lang.org/docs/get-started/introduction/ Type: article Domain: pomsky-lang.org Notes: Interesting but not for me. I know regexps are arcane and confusing but they are well documented and people know them. I put this in the same bucket as scss and sass and many other helpful pre-processors. Not for me. Of course, you may not know that C++ started out literally as a C pre-processor (called cfront) that would generate C. So... The author says: "Summary of what pomsky is and what it looks like. Pomsky is a language that compiles to regular expressions. It is currently in an alpha stage and will likely change in the next few releases."

What Can We Learn from Barnes & Noble's Surprising Turnaround?

What Can We Learn from Barnes & Noble's Surprising Turnaround?

Source: tedgioia.substack.com

I was in a Barnes and Nobel again after many years. Actually many years before that I would go to a B&N more than once a week. Then between Amazon and terrible inventories at B&N and Kindle and Nook I stopped going. Then a few weeks ago I visited one and it was a revelation. I had a great time browsing books and books and books. Great article:"Digital platforms are struggling, meanwhile a 136-year-old book retailer is growing again. But why?"

This is a really cool algorithm that i never heard of. Also geohashes are not too hard to compute and have very useful and unteresting properties. the concept of a z-order curve is explained. That too is a useful model and concept. The author says: “Latitude and longitude as a locality-preserving string.”

Source: github.com

This seems like a very nice simple tool to solve a common problem. My only confusion is that there are a bunch of similar tools to do the same thing. Each has its own DSL, written in ruby or some other language, has its own conceptual steucture, and its own bugs. It’s enough to make me decide to just keep doing it by hand. Heres what the author says: “ Prepper is a simple server provisioning tool, built on top of SSHKit.
