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 they need a 6x6 or 4x6 grid. I'm quite fond of Spleen

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 architecture with nothing besides the shell. Unfortunately

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 not support it), and last I checked zfs can't grow a par

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 a linear search through an array; you just change

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 code. I wonder how much work it would take to

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 machine. The stage0/live-bootstrap team has already accom

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 abandoned it. Forth has been suggested often for bootstrapping a

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 32-bit floats. I imagine the other BASICs have similar limi

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 complaints that old rustc would take many hours to compile it

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 memory, and then jumps to it. You need some way of getting this

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 and it's one the bootstrappable team tend to f

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, and you can't skip any steps because, like he said,

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 equivalent with their own secret firmware. Almost all moder

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 another name for it.) They've gotten to the point

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 small C compilers lately! - TinyCC, SCC (Simple C Compile

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 talking about this, and why, as a society, we try to police i

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 makes it hard to find.

A killer feature of C is its simplicity. It is so simple that there are dozens, probably hundreds of independent C compilers and C standard libraries. Rust has no formal specification and no independent implementations even close to complet

That's only in C++. As far as I know in C you need to name all parameters (although maybe that rule has been relaxed in newer versions of C.)
