I had applied to this program once. I had suggested to draw people from an agricultural background (willing to put in long hours on dirty jobs), long distance runners (short term motivation, higher caloric efficiency), civic-minded volunte

Yet the code is hosted on Github ( https://github.com/jozefg/pcf ) and it generates C. Worse is better.

There are environments that do not have a strong distinction between OS and language. While adored by their users, for some reason they are never very popular. Oberon, Smalltalk and the old Lisp Machines come to mind. (Maybe Forth too, t

What are your thoughts on embedded scripting languages, for when your C needs a little more runtime flexibility? There are a few written in C and are designed to be slotted into a larger C program. If you want to start a "computer vis

It is just like optimizing any piece of code. Log everything, identify hotspots and improve them. 1) Time yourself. Keep a little text file with timestamps and brief fragments of what is going on. Do this every time you have a mental con

With regards to typing, find some fingerless gloves you like. My favorite pair is under $10 and wool, but instantly makes anyone who tries them on look like a hobo. Add extra insulation on your arms too. The gloves are also essential if

The Gorard one looks very familiar and is old enough too. Going to go with memory rot changing my other details. Thank you!

Nope. The alternative (mean average distribution) also has the same units. The problem with the MAD was that it used an absolute value and so introduced a discontinuity. If you are a mathematician working with a system of equations, each

How large is "sufficiently large"? Usually I write error handling code that could use goto as a state machine. This makes the code much more readable because the whole activity should have been a state machine in the first place

There was a similar blog post a while back about the standard deviation in statistics. About how when the SD was discovered, the original paper was full of disclaimers that the SD should only be used by statisticians working with perfect d

Ethically if it is truly nothing more than a cost saving measure, you'll do the $0 option and release a completely unsupported server disk image for people to self-host on their LAN. Think of how much money you can save on CPU and net

Laser cutters are probably where it is at. They are lower maintenance, faster and can make sturdier objects. But not like this: "A camera inside the laser cutting chamber and image processing in the cloud will take the place of a pa

Your friend spent years studying. He also had the sense to pick one of the most hospitable and temperate locales in North America. And even in a friendly environment, he acknowledges that he needs more supplies than he could easily carry.

The Hall-Heroult process did not exist, regardless of powerplants. Aluminum was more expensive than gold because it could only be produced by non-electric vacuum smelting. (While there was not a "huge number" of generators there

I wonder what you would have said about aluminum in the 1880's, back when it was a useless novelty for the wealthy. After all, the fast majority of applications are satisfied just fine by cast iron, brass or pewter. At the time at lea

Um, no. I did not say anything like that. But go ahead and rigorously demonstrate any non-zero existence for "A truthful bear saw a fox, though the thief is a raccoon" with the current parameters of the model. It is not a possib

That everything is completely independent? This is the correct, non-naive assumption to always make unless you have a very good reason otherwise. There are 3 binary variables. Some combinations of the variables are impossible. These impo

I'm reasonably certain no camp would claim the statistical equivalent of BogoSort as a method. 98% of the loop cycles (and 98% of the random numbers generated) make no contribution to the result and are thrown away.

Just to be clear here: yes, he is using a 32-bit 72 MHz Cortex M4 and a 12 MHz Cortex M0 as an IO controller for an 8-bit 8MHz cpu. It also appears that the ram for the Z80 is coming out of the 64KB built into the M4. Even the MCUs built
