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?

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.

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.

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.

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.

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.

How GPUs Work 12 years ago

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.

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.

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.

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].
