I'm trying to compile for FreeBSD, but main file graphscad.py is missing in the repository on Github. Please update.

In the book "I, Woz", Steve Wozniak explains that Jobs hired a random hacker Rod Holt to design switching mode power supply unit for their Apple II computer. Jobs paid him $200 a day which was a lot of money by that time. Rod did

Thanks for sharing. Googling for "SCRIPT/VS" gives the only link pointing to somewhere in the middle of IBM's z/OS manual. Must be a lost alien technology by now.

Sadly, neither Inkscape nor GIMP still supports CMYK color space natively which makes these tools difficult to use for commercial printing purpose. Beside that Inkspace is pretty cool piece of software.

No matter what IBM does, it smells like FORTRAN. Jokes aside. Anyone knows what software did they use back in the days to write such beautiful manuals with keycaps and other icons ? Was it TeX, troff or anything alike ? I have old Atari man

A completely useless use of silicon. The fastest way of copying memory block is to offload it to DMA or some other dedicated hardware. Using CPU to copy blocks is just a stall. And please, do not call ARM a RISC!

Well, I have a doubt that simply increasing bus size to 64 bits you can get working bitstream for FPGAs, even for top notch ones. Something tells me that synthesising/placing/routing such soft-core will face timing and resource li

Although I completely agree with you, I cannot help but remember "640K ought to be enough for anyone" by W.H. Gates.

SCALL instruction, used in his example, has been renamed to ECALL. Not a big deal though.

Besides, text messages compress very well. Yes, I vote for NNTP. In my previous life I used to run a local NNTP/Usenet/Fidonet gateway, storage was not an issue at all, but bandwidth was.

Since antenna efficiency directly depends on it's size-to-wavelength (resonance), to get them working we have to deliver power at extremely high frequencies, like 3e16 Hz I quess, which is not feasible.

Although I like a lot big heavy SUVs (I own a Toyota LC200 diesel), I recently bought myself an EV scooter. It appeared it is pretty much more convenient to navigate through downtown using this small EV - it is ubiquitous, faster, brings jo

Fascinating book indeed. I read it when I was a student some twenty years ago, I had been astonished by simple and clever trick Godel used to prove his theorem - to digitize everything, then operate with just numbers.

I bet there's a similar mode for all intel's CPUs, which are RISC in essence.

I would like to see a superscalar OoO CPU with a RISC-V ISA. Since RISC-V cores tend to be very small, I would expect to see a CPU with hundreds of cores.

Elbrus 2000 is a mass-produced VLIW microprocessor with binary translation of x86. There is a set of different models having different number of cores and DSP blocks. https://en.wikipedia.org/wiki/Elbrus_2000

Some consider E2K (Elbrus 2000) as successor to Transmeta Crusoe and it is not effected to Spectre issue. It does binary translation of x86 code as well and quite fast (20% preformance loss).

Good read. It must be noted this article discusses von Neumann architecture and alike (Harvard).

The thing is that it is impossible to compete with a chinese made appliance just by selling a product that will last. You have to sell it for the price significantly lower in hope to return investment by selling locked cartriges. That is wh

Replace PCB with your own one having MCU with buit-in EEPROM. Add a tiny push button (or just two copper pads), pressing/closing which will dischage a capacitor indicating "need to rewind" to an MCU. When counter is zero, you

Personally I do not like Arduino (and its IDE) because it hides many complex things under cover. But, really good thing about it is that programming microcontrollers like this teaches you to keep your code lean, worshipping any single byte

I don’t understand why “bloat” is considered an argument these days. A Quartus installation is 10GB. Last time I tried it, it was just 4GBs and that was couple of years ago. Did they really improve so much in their design software ? I rea

I confess I downloaded and installed Quartus couple of times, yet never dared to use it.. Every time I tired, it went against my subtle soul. :) I believe, sooner or later more vendors hop on the train and get their FPGA inners documented a

Any kind of complex project can be implemented just using a small set of features/tools, do not get yourselves depraved. Modesty is the beauty! I'm very very much greateful to Yosys/nextpnr and VexRiscV/SpinalHDL develop

You don't put printf() in critical sections, instead you collect some statistics. Once critical section is over you can freely print collected data for further analyzis. Or you can print it once a second. This simple technique works we
