I know this is somewhat tongue-in-cheek, but what would the long-term consequences be of importing large quantities of hydrogen from off-planet and then binding it to local oxygen? I suppose if we had the tech to do that, we might be able t

Back when I worked at Target, it was also this way. As I understood it, the system simply did not allow for a multiple item discount. The "3 for $4" ads did always say, in fine print, something like: unit price $1.33. What got m

I'm curious why you wouldn't recommend it. I've never used it myself, but I've been reading about it the past few weeks. The design seems really well done compared to init.d scripts in the sense that every init script

I wonder if there's an element of users learning how to optimize their query for Duck Duck Go. I've been using it as a default for some months now, but I often fall back to Google for software error message strings and other thin

But not every car has that. I've been in a ~6-8 year old Honda Civic that lacked any indication as far as I could see.

I don't have numbers, but back when I had no dental insurance, my dentist reduced the price without any prodding. I'd be surprised if this wasn't common.

Tomcat (and other app servers) has support for doing hot reloads of Java web apps while not reloading the HTTP layer (and not dropping TCP connections). http://www.javacodegeeks.com/2011/06/zero-downtime-deploymen.

The claim that a 4-minute mile was once thought to be impossible by informed observers was and is a widely propagated myth created by sportswriters and debunked by Bannister himself in his memoir, The Four Minute Mile (1955). The reason th

I suppose the author was trying to be explicit for the sake of a reader unfamiliar with Ruby. The typical way to avoid that boilerplate is by using 'attr_accessor :sanity', which defines those getter and setter methods (and it is

Is it possible your bad knees make running unpleasant and not the other way around? Does your condition have a name? I've not seen claims of long-term injuries (as opposed to acute injury) that have names other than osteoarthritis. Th

I actually find PulseAudio vs. JACK incredibly annoying. I like to play around with "professional" audio. I don't consider it professional, but more relevantly I like to play with certain apps that require JACK. It's certainly an RTFM thi

That's a good point. I'm young(ish) and tend to race my past self (while following traffic laws). On one hand, what's the point of biking if I can't get to work faster than by bus? But on the other, a more leisurely pace would surely lea

I've been lucky to work in areas where theft isn't a huge issue. My biggest problem is the weather. In the hot, humid summers, I wish my building had a shower, or at least some area to change clothes larger and less smelly than a bathroom

It also, unlike tar.gz, provides an index for easily seeking to and extracting just one file from the zip archive. My understanding is that doing this in a .tar.gz means unzipping and processing the whole tarball as a stream.

No conflicts, but a tradeoff of loading two versions of library C. I assume at some point, the cost of multiple versions of everything (in terms of memory usage, for example) becomes an issue?

For the sake of curiosity, I happen to have recently done a benchmark of a "hello world" rack app (literally just responds "hello world" to every request) on a number of Ruby servers (mostly JRuby, but also Puma on MRI). They were all run i

I have found RESTEasy (and likely any JAX-RS implementation) to be very nice for creating simple services. With various annotations and static typing to automatically convert various parameters into function arguments, it's easier than Sin

Another option is to build an index of the various parts of $LOAD_PATH. I monkeypatched (JRuby) to do this at runtime (that is, re-index every launch), and I saw a modest speed up in Rails boot time. If there were a standard way to build

Part of it must be that binary search only works on a sorted array, and most arrays won't be sorted. Followup question: are there other common array operations that only work on arrays in a particular state? Are any of these in or out of v

One of my fears about telling kids to defend themselves with force is what if the bully has a gang of friends? An older brother? Access to a weapon? How likely is it that a bully, finally beaten by the victim, escalates further?

I, too, would love something like this. You're probably aware, but it's possible to host private gems in a simple static webserver. We have our CI server copy gems over and run a script that calls "gem generate_index -d /path/to/gems". Com
