> Current F13 expansion cards will pull out sometimes Just echoing what others have said here: I'm typing this on an original F13 I think from batch 6 which has had many upgrades b…

The 5x5 is very nice, and the 3x5 isn't bad either. Unfortunately neither of them have all of ASCII. The size is also a bit misleading because you need to add spacing so really the…

I'm the author of Onramp. Thanks for linking it! One of the VMs I wrote for Onramp is in POSIX shell [1]. This was intended to make C bootstrappable on any POSIX system of any arch…

I just use ConnectBot to ssh to my house. It runs tmux and vim well, especially with a little pocket-size folding bluetooth keyboard to go with it.

These filesystems are not really alternatives because mdraid supports features those filesystems do not. For example, parity raid is still broken in btrfs (so it effectively does n…

Here's a link to the case on the Framework marketplace: https://frame.work/ca/en/products/cooler-master-mainboard-ca... I put my original mainboard in one of these when I upgraded.…

Indeed, a decent closed hash table is maybe 30 lines. An open hash table with linear probing is even less, especially if you don't need to remove entries. It's almost identical to …

Oh, amazing! I've heard of DuskOS before but I didn't realize its C compiler was written in Forth. Looks like it makes quite a few changes to C so it can't really run unmodified C …

Indeed! An eventual goal of Onramp is to bootstrap in freestanding so we can boot directly into the VM without an OS. This eliminates all binaries except for the firmware of the ma…

Author here. I think my opinion would be about the same as the authors of the stage0 project [1]. They invested quite a bit of time trying to get Forth to work but ultimately aband…

That might be rather more difficult than you might expect. Advent of Code uses quite a lot of 64-bit numbers. A bit of googling tells me C64 BASIC only supports 16-bit integers and…

The current version of rustc may compile itself quickly, but remember, this is after nearly ten years of compiler optimizations. Older versions were much slower. I seem to recall c…

The minimum tool that bootstrapping projects tend to start with is a hex monitor. That is, a simple-as-possible tool that converts hexadecimal bytes of input into raw bytes in memo…

The generated C code could contain a backdoor. Generated C is not really auditable so there would be no way to tell that the code is compromised.

It can be difficult to explain why bootstrapping is important. I put a "Why?" section in the README of my own bootstrapping compiler [0] for this reason. Security is a big reason a…

While it is technically possible to bootstrap Rust from Guile and the 0.7 Rust compiler, you would need to recompile the Rust compiler about a hundred times. Each step takes hours,…

It is true that there are many layers of code below the OS level. UEFI for example is probably hundreds of thousands of lines of compiled code. Modern processors have Intel IME and…

The team at bootstrappable.org have been working very hard at creating compilers that can bootstrap from scratch to prevent this kind of attack (the "trusting trust" attack is anot…

> That’t not "doing sketchy shit with people's data" Of course it is. If you add AdSense to your website you are letting Google track your users in exchange for a cut of the profit…

I was definitely hoping for a look at modern compilers. This article was written last month, yet its history ends with the release of LLVM. There's quite a lot of development in sm…

8BitDo makes great controllers. I have an SN30 Pro, a Zero 2 and a pair of Ultimate Cs. All of them have been used extensively and they are all excellent quality. On the other hand…

Do you at least have sympathy for yourself? These anti-competitive behaviors are causing higher prices for consumers. That includes you. The costs to consumers are why we're talkin…

I've been using this since Simple Mobile Tools was sold. It works well. My only real complaint is that the app icon name starts with "Little" so it's sorted under L, not F. It make…
