yan··on RattleCAD
Can you share more about where you took the class? Continuing education, or a vocational school? Did you take it purely as a hobbyist, or hope to get into the trade?

yan··on How People Get Rich Now
To solve the wide-screen, narrow text problem, I once threw together a demo with a hacked up Chromium/WebKit to create a flowing, multi column view mode that created a long virtual scroll surface and scrolled it like newspaper columns: https://vimeo.com/59463521.

It wasn't super intuitive, but wish a modern browser had this.

yan··on Ask HN: What projects are you working on now?
I believe what you’re looking for is: https://www.telescopictext.org/ (demo is at .com)
yan··on Goodyear Inflatoplane
This is essentially how a wingsuit works, although inflation happens in flight through inlets. That is in general how nylon wings (e.g. paragliders) work as well.

yan··on The Crash of ’87, from the Wall Street Players Who Lived It
Did your degree help you with that decision?
yan··on IDA: What's new in 7.00
You'd be remiss if you don't mention Binary Ninja[1]. A relative newcomer that's already extremely capable, has great scripting support and is under very active development.

yan··on Surviving injuries from falling
If you're healthy and using a normal, dynamic rope, no it won't. It won't even hurt. A factor 2 fall onto webbing or dyneema can totally mess you up though, even from a couple of feet.
yan··on Surviving injuries from falling
Unsafe for what? Almost all of the fall forces should be dissipated by a dynamic rope, not the harness.
yan··on Ffffound is shutting down
Man, talk about the ephemeral internet: One of my first projects[1] in Haskell was a small tool to go through my Google Reader favorites and download posts I tagged on ffffound.

yan··on Why Some Cars Have Gas Tank Fillers on the Left or the Right
Something that made filling rentals cars easier: there's a triangle on the dash that points to which side the cap is on next to the "fuel" symbol on all the cars I've been in.
yan··on 2017 Levchin Prize for Real World Cryptography
Moxie explicitly gave Zizek credit in his speech.
yan··on Atmospheric carbon dioxide passes 400ppm
He addresses that in the book as well. His goal is to give rough estimates and a framework to reason about energy sources, not provide conclusions.
yan··on Atmospheric carbon dioxide passes 400ppm
I recently started reading "Sustainable Energy Without The Hot Air"[1], which is available as a free book, and it's been a wonderful introduction to reasoning about alternative energy. The author also gave a talk a few years ago that is very approachable[2].

yan··on Learning Web Audio by Recreating the Works of Steve Reich and Brian Eno
When I first discovered Music for 18 musicians, it's all I'd listen to while working and commuting for weeks and weeks.
yan··on Alan Kay has agreed to do an AMA today
What most recent topic in the field of programming languages, or computing more broadly, have you changed your mind about in a substantial way?
yan··on Tokamak: A Rust IDE for Atom
I agree it sounds similar, I was just pointing out that it's likely a reference to the plasma device and not a comment on Mac computers.

yan··on Image Processing 101
Slightly related, but I had a small epiphany when taking a class on DSP on Coursera. The kernel that is used to blur an image and that which is used to remove the treble/high frequencies from an audio sample are identical, except one is in 2 dimensions and the other is in 1. And this makes perfect sense! A low pass filter removes high frequencies, and sharp edges are high frequencies in the 2D plane.

TFA only mentions Gaussian blur, but a Gaussian blur is just a moving average, with "closer" pixels being valued higher, plus a smooth falloff. When you replace each value with an average of its neighborhood, you "soften" the transitions.

yan··on DspGuru
For anyone interested in DSP, the Coursera DSP class is superbly well done: https://www.coursera.org/course/dsp
yan··on Microsoft Open-Sources Git Credential Manager for Mac and Linux
It is. ssh-agent caches it though.

To paraphrase Jay-Z: he's not a C++ developer, he's C++, developer.
yan··on Concise electronics for geeks (2010)
Speaking of, after getting the third edition, I have the second version sitting unused. If anyone wants it for the cost of shipping, let me know.

yan··on How GPUs Work
If anyone is even marginally interested in GPU internals, you'd do yourself a favor by checking out John Owens' UC Davis class on the topic[1]. I once watched the first lecture just to fill an hour and ended up going through the entire course within the span of a week, following up with my own research later on. Superbly interesting.

yan··on How speakers make sound
eevblog is wonderful! During a recent side-track into electronics, I've been consuming all of Dave's (EEVblog) videos, all of Mike's (mikeselectricstuff) videos and all of Ben Krasnow's videos (Applied Science).

EEVblog is very specific to EE, Mike's Electric Stuff is electronics as well, but tends much more toward tear downs/obscure components/reverse engineering and Ben's channel is just a delectable collection of DIY everything. Ben became famous for building his own (and probably first DIY ever) electron scanning microscope, but has videos where he builds all sorts of amazing things in his home shop.

yan··on How Does a Debugger Work?
A breakpoint instruction is usually a single byte in variable length instruction ISAs and the same width as any other instruction on fixed width ISAs, so inserting a breakpoint is just overwriting the first byte of an instruction and keeping all other offsets identical.
yan··on My adventures in CNC robotics
Zalewski was the reason I felt unaccomplished in 2005, when I read his "Silence on the wire" and noted he wasn't much older than I am.

His separate guide on CNC is great[1]. He also has a great intro to electronics[2]. His first book is an amazing survey of totally passive attacks[3]. His second book is a comprehensive survey of web application osecurity[4].
