The first footnote of the article says: > While that could mean just about anything, nearly everyone who writes a half-decent hand-written parser, whether they know it or not, is w…

I don't know if I would call it "good" but if you're willing to settle for "official" there is http://www.ti.com/tool/MSP430-FLASHER which will work with TI's own MSP-FET on all th…

I'll second my sibling comment in saying that C (and C++!) will be around for a long time, and is epically easier to get hired with if you're trying to break into the industry. The…

I agree with your sentiment, but I think the situation is a bit more nuanced. The usual argument is that headers don't actually provide good encapsulation: implementation details i…

By my reading that implementation was assembled by humans, not the optimizer. Although, there's certainly nothing magical that prevents the optimizer from generating such code. Her…

A good interview exercise (not necessarily vouching for fizzbuzz here) allows depth of discussion past the initial answer. It is in this discussion stage where I spend the majority…

I don't think the your parent was talking on an individual level, but a more macroeconomic level where this appears to not be happening[1]. [1] http://www.winningwordsproject.com/a…

The worst one--which to be fair, is specifically warned against on the site--is that you can't really use local variables. The technique is useful to a point. I used a similar tech…

Glib response: :s/t:50/t:60/g More serious response: I think after many years of training ones brain to use the features available to it some of those features become second nature…

Or press "brightness -" until they turn off...

I'm also too lazy to actually do the calculation, but to a Fermi approximation XKCD has already more or less proven[1] that it's not terribly practical for a homeowner as an energy…

Fair enough. The Cortex-M's that I've dealt with have generally been homed inside some larger chip, and so the "reset pin" notion was a bit more vague, and in such an environment A…

I don't mean to be a party pooper since I've done my fair share of hacky workarounds in v7-M processors and it is always exhilarating when it works... But since I'm a Cortex M fanb…

Clearing an arbitrary bit actually is supported (as mentioned in the article: "you can set, clear, or toggle any bit with one instruction"). The specific details require you to dig…

Thumb-2 immediate encoding is even more gleeful--in addition to allowing rotation, it also allows for spaced repetition of any 8-bit pattern (common in low level hack patterns, lik…

I don't know about "a ton" -- there are far better ways to move around a file than mashing hjkl, even with numbered versions (vim-easymotion, vim-seek). Once you can get to the rig…

The very next slide cleans it up using a "utility type" which reminds me of the "monadic" Haskell solution.

It's been a while since I used Gentoo, but most of the serious users consider build-from-source as a feature and don't penalize portage for that. I believe your parent is referring…
