Unlike previous OSes, UNIX provided the pipe facility to allow you to combine the functionality of many small programs. Ex. ls | grep ... | sort ... | more Before that every command-line program had to support the full suite of additional f

If we analyze the computational complexity of software architectures the way we do regular algorithms, we see that UNIX was much more efficient than previous OSes/approaches. It's demonstrated in this short video: https:/&#x

I worked at Google on a project called the Chrome App Builder which would let you create simple Kiosk apps which ran on these kind of devices. It wasn't uncommon for companies to buy these 5 thousand to 20 thousand at a time to run the

I would say that the best programmers don't change the multiplier, but the exponent, so that the factor by which they're better than the average increases with the size of the problem. This is why you might not see as much of a bi

I don't think it's because of the milk lobby (which didn't exist until early 1900s according to other posts) because I once browsed a cookbook from the 1800s and noticed that many of the recipes called for an amazing quantity

When we designed to UI library for FOAM in 2011 at Google, we did extensive benchmarking, and discovered that DOM calls were very slow and that we could greatly improve performance by batching them. Yes, in the end, you still need to make D

Correct, no single interface does what the UNIX pipe did for command-line text-based IO-stream processing programs. In FOAM, we have about 20 standard interfaces, which correspond to your different glue types. Things like DAO (Data Access O

I'm not advocating a closed system. Just like UNIX doesn't lock you in to any hardware or CPU vendor. FOAM is open source and most of the functionality is provided by existing languages, libraries and databases.A universal adapter

The article seems to claim that if we did as he says and rewrote all of our code to be data-oriented instead of object-oriented, then our code would run ~2X faster and all of our performance problems would be solved. However, I got my first

The results are compatible with "risk homeostasis" or "risk compensation" theory. People who use unit tests have an increased sense of safety, so are more comfortable living with less-safe designs and code-bases. "R

The 7-GUIs suite looks better, but so far only one JS framework implements it. The problem with more realistic benchmark apps (or suites) is that they require more effort to implement, so you have a selection bias towards easy-to-implement
