You were in good company. The Xerox Alto CPU used four 74181 ALUs.

I've looked at a few dozen of the designs featured on the front page, and most of them don't make sense. What is the purpose of this?

The 80s kid me lived in a small town with no access to technical manuals or people who could help. The developer manuals for $80 each or a compuserve account to get access to the source code examples of the manufacturer were completely out

Spanish vale and English value have the same Latin origin. Persian bale is an Arabic loanword.

When reading an article written by Bjorn Lomborg, you should also do the effort to read the cited sources. This is not an ad hominem attack, just an observation. Do it and you will see.

The title says "dialects" but most comments here are only about accents. Can people here give examples of non-standard grammar or vocabulary (that goes beyond some temporary slang or subculture words)?

Great article. Wish list of topics to add: - branch predictors that can detect patterns (edit: I guess it's already covered in the paragraph about raising prediction accuracy) - LRU-approximations in L1 caches - Data prefetching (seque

I highly recommend the NHK documentary "10 years with Hayao Miyazaki" that shows how he works (and also his sometimes difficult character).

Ah, that makes more sense than my theory. It's a weak copy protection method, though, as you can just try and see what happens, and I think they dropped it in M&M3.

A few years ago, I decompiled a good part of the PC version of Might & Magic 1 for fun. According to Wikipedia, it had been released in 1986, although I don't know whether that refers to the PC version or to the original Apple II v

That's funny because I have two objects on my desk for which I know that they use 555s. One is a no-name joystick with "autofire" function from the late 1980's. The other is a mass produced motor controller from the 2000

I don't know much about app development, but I was curious and downloaded the Albert Heijn apk for ARM64. Inside the apk, the three largest entities are: - libflutter.so 140 MBytes (flutter, obviously) - flutter_assets 29 MBytes

Similar results here. I'm curious to know what the problem of Firefox is. For example, the 3d-raytrace-SP benchmark is nearly three times faster on Edge than on Firefox on my i7 laptop. The code of that benchmark is very simple and mos

There are two approaches (sometimes mixed): (a) you reverse engineer the application writing or reading the file. Even without fully understanding the application it can give you valuable information about the format (e.g. "The applica

Yes, but that's my point: the ARM2 cannot get faster than 1.25 MIPS in an Amiga because of the memory bandwidth (assuming that the CPU uses 5 MBytes/s of the available 7 MBytes/s that it has to share with the graphics chipset

by tralarpa 11mo ago
I wonder how much faster the ARM2 would have been compared to the 68k in a first-generation Amiga. The Amiga's chip memory only delivered 7 MBytes/s, shared between the CPU and the chipset! With its 32-bit instruction words, the A

French orthography competitions are on a different level. Spelling of difficult words combined with grammar rule exceptions.

Sources generally seen as authoritative (Duden, Wahrig etc.) estimate that the German everyday language has between 250,000 and 500,000 words (depending how you count), without counting technical terms.
