Where does a web-dev turn to to get started in this as a hobby?

No matter what you do, you NEED tools. I cannot stress this enough. If you can spend $250-$500 on a nice desktop scope, awesome. If you only have $80, you can get a serviceable Hantek USB scope that will at least give you an idea of what you're doing. If you can only spare $20, you can at least get an el cheapo JYETech scope. In addition, you'll want to pick up a multimeter and probably a logic analyzer. Again, no ne…

Good advice but I actually found FPGA very hard to start or very expensive. May be you can give more hints.

I honestly thought you were gonna reference the Four Yorkshiremen sketch by Monty Python after the second line!

Predates Python by a couple years. It’s from “At Last The 1948 Show” from the 60s.

Didn't know that. Thanks for sharing.

You were living large! My first Linux computer was a 20Mhz 80386SX with a 40MB hard drive partitioned half for Windows 3.0 and half for Linux (SLS) and swap. It had a whopping 4MB of RAM and I also compiled my own kernel making sure to trim down features as much as possible. It was magic seeing X11 come up for the first time just like the big-bucks Sun boxes!

Hah, you had it great! My first PC was a 286, which IIRC either had no HDD, OR. 20MB HDD (might be mixing it with our next PC, which was a 386). I'm pushing 40, and still shake my head in wonder sometimes about just how much is possible at such small scale and cost. But this is now turning into "when I were a lad..." :)

Mine was too, albeit 40MB had and a CD tom!

Ran windows 3.1, Civilisation (VGA graphics), railroad tycoon, Star Trek 25th anniversary - and could have them all installed at the same time. Other programs included championship manager 93, and I think day of the tentacle.

But it wouldn’t run Linux - 386 and above.

I once read somewhere that the time to compile Linux from source on high-end desktop hardware has remained remarkably stable over the years.

I'm convinced that compiler speed is all a matter of how it was initially designed. Take for example Delphi which can compile millions of lines of code in under a minute or something ridiculous. Then we have D, Go, Rust, and such, they compile rather large codebases that would take C++ a good 30 minutes on high end hardware of today in shorter spans of time (not as familiar with how fast Rust compiles, but I know Go…

The best part about Facebook's preprocessor (warp) was that it was slower than Clang (https://news.ycombinator.com/item?id=7489532).

But the preprocessor isn't what makes compiling C++ slow. It's a combination of the complex grammar, and ahead of time optimization of a (mostly) static language. Turns out you can compile code really fast if you don't actually try to optimize it.

I get serious Snow Crash vibes from this.

Thats where I thought it was from lol

oh kids! i used to crank the wheel by hand on my analytical engine that my hacker friends and me built after there was a leak of babbage's plans! he never knew! you kids and you petabytes of ram! back in my day.... /s (i'm looking forward for these comments to be commented on a certain website i'm not supposed to name)

you kids. We calculated with charcoal on the cave's wall while the adults were out hunting for wooly mammoths... ZX81: Z80/1KB RAM... more recently though PIC12 (C501 IIRC) ...

I'm slightly surprised nobody has yet linked https://xkcd.com/505/

Fair enough, thanks for that, I wasn't sure, all my Rust programs have been small enough to where I havent noticed. I wonder if it would of made sense for Rust to consider this earlier on in the same way that Pascal did. I believe I heard Pascal was designed to be parsed easily by machine code.

Parsing is not the reason why it takes a while to compile.

"Parsing" was probably not the best choice of word on the GP's part, but they meant that Pascal was specifically designed to be implementable with a naive single-pass compiler; of course that would exclude many optimizations we take for granted these days.

To me it's truly mind-bogging that a tiny $1.42 chip contains almost everything needed to boot Linux: a 500mhz cpu, 32MB SDRAM, 2D GPU, SD/MMC support, and USB controller, all packaged inside a 10mm x 10mm chip? It makes me really want to get into embedded development.

Twenty years ago, a car stereo that ran Linux https://en.wikipedia.org/wiki/Empeg_Car https://web.archive.org/web/20000815214315/http://wired.com/... was the toast of Slashdot https://tech.slashdot.org/story/99/03/03/1216251/linux-power... .

I wonder how many Linux instances are running in an average modern automobile.

It’s an A9, same as on Xilinx Zynq 7000 series, 32-bit ARM core with full MMU.

No the zynq chips have a cortex-A9, which is armv7, this is armv5. It still does have a MMU.

For comparison, the Raspberry Pi 1 had an armv6 core.

It's from Gibsons "Virtual Light", a vastly better book than Snow Crash. Highly recommended!
