Summary: jq rocks for speedy JSON mangling. Use it to make powerful git clean filters, e.g. when stripping out unwanted cached-data from Jupyter notebooks. You can find the documentation of git 'clean' and 'smudge' filters buried in the page on git-attributes , or see my example setup below.
I had been programming in Fortran and assembler for a number of years when I got my first personal computer. It was exciting. On the first generation PC one had to toggle in a paper tape loader from front panel switches, byte by byte, then start the paper tape reader and then one could output to the led on the front…
Sandspiel is a falling sand game I built in late 2018. I really enjoyed writing this game, and wanted to put into writing some of my goals, design decisions, and learnings from that process. If you’re reading this but haven’t played sandspiel, you should probably go try it !
Random code snippets, projects and musings about software from Eric Kidd, a developer and occasional entrepreneur.
Ah, C. The best lingua franca we have… because we have no other lingua francas. Linguae franca. Surgeons general? C is fairly old — 44 years, now! — and comes from a time when there were possibly more architectures than programming languages. It works well for what it is, and what it is is a relatively simple layer of…
"JVM Anatomy Quarks" is the on-going mini-post series, where every post is describing some elementary piece of knowledge about JVM. The name underlines the fact that the single post cannot be taken in isolation, and most pieces described here are going to readily interact with each other.
Your CPU has a 32-bit addition instruction that computes the sum of two 32-bit integers x and y, producing a 32-bit result. (The 33rd bit of the sum, the "carry bit", is usually thrown away.)
This tutorial will show you how to write assembly language programs on the x86-64 architecture.
Fellow core developer and Canadian, Mariatta, asked on Twitter about python -m pip and who told her about that idiom along with asking for a reference explaining it: I learned sometime ago that we should be doing `python -m pip install ...` instead of simply `pip install ...` but now I can'
A vision for empowered computing that reaches back forty years. Our research lab examines why it has been so hard to achieve.
Many people who use Rust for a bit - especially those who like the language but do not fall in love with it - feel a sense that there must be a smaller, simpler variation on the same theme which would maybe be a little less powerful, but would also be much easier to use. I agree with them, but I think they are almost…
Software Architecture is the important aspects of a software system's internal design, usually its major components and aspects that are hard to change.
I am an unusual beast. All my solo project games I've been making recently have been written in 'vanilla' C. Nobody does this. So I think it might be interesting to explain why I do.
When we implemented the git portion of Sublime Merge , we chose to use mmap for reading git object files. This turned out to be considerably more difficult than we had first thought. Using mmap in desktop applications has some serious caveats, and here's why:
In 1963, the philosopher Edmund Gettier published a three-page paper in the journal Analysis that quickly became a classic in the field. Epistemologists going back to the Greeks had debated what it meant to know something, and in the Enlightenment, a definition was settled upon: to know something is to have a…
Today Eclipse Foundation’s president Mike Milinkovic blogged about the final result of the confidential trademark negotiations between Oracle and the Eclipse Foundation. As we remember, Oracl…
Introducing DTrace on Windows 10
Dash knows your context, your team, and your work, so your team can stay organized, easily find and share knowledge, and keep projects secure, all from one place.
To give users more control over their extensions, support for sideloaded extensions will be phased out starting with Firefox 73.
I saw this question on the Software Engineering Stack Exchange: What are the barriers that prevent widespread adoption of formal methods? The question was closed as opinion-based, and most of the answers were things like “its too expensive!!!” or “website isn’t airplane!!!” These are sorta kinda true but don’t explain…
Dynamic programming has a reputation as a technique you learn in school, then only use to pass interviews at software companies. Indeed, most developers do not regularly work on problems where dynamic programming is needed. Ultimately, dynamic programming is a technique for efficiently solving problems that can be…
