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 writing a recursive descent parser [1]. > [1] Parsing E

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 three

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 C ecosystem just has too many advantages at this

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 internal to the class (i.e. private members) end up ge

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. Here's something[1] I just threw together that (ab

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 of my time with a good candidate. In such a discussion we

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 technique for a project and the inability to use locals th

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 and subconscious. This is great for editing

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 storage solution. [1] https://what-i

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 ARM's stance makes a bit more sense

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 fanboy I have to defend its reset capabilities :)

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 a bit past explaining just the immediate encodi

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, like from [1]) to be encoded in single instructions. For those

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 right place in the file I almost never use hjkl

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 to the sometimes annoyingly long dependency computation ti

The example definitely leaves a bit to be desired. One great story for why this way might be better is that with a small tweak (to allow dynamic [de]registration of command functions) it is much more open to extension. To continue using the

That's funny--as a python guy I was squirming for a set comprehension immediately: >>> a = {'a':1,'b':2} >>> b = {'b':3,'c':4} >>> def keylist(*maps): ... return ', '.join(sorted({str(k) for

In re your first bullet: If such things are important to you, it looks like you can produce fixed size packets through a variety of methods. In particular, they support overlength encodings.

Secondary tip: to access via the UI instead of search, at some point Google decided it'd be cool to make you click the ">>" button for a "live preview" before showing the "cached" link.
