> understand your problem domain It sounds like the article's explanation of how precision erodes as the number increases would help a lot when thinking about this. A good epsilon is a function of the size of your numbers. I've

Good riddance. Red delicious apples get mealy fast, sometimes before you buy them. I kept waiting for the article to acknowledge this, and the closest it came was "tastes have sifted." Bah, who has ever liked a mealy apple? Gala,

This may have come from a site like talentbin.com, which gives recruiters a keyword search based on profiles from Github, StackOverflow, etc. I worked on a competing site for a bit until I decided it was a force for evil not good and shut i

I believe even if you don't share your email address on Github, someone can still pull it out of your commmits. At least that used to be possible.

Whatever scale you use, this article has good advice on how to compute each item's total score for sorting purposes: http://www.evanmiller.org/how-not-to-sort-by-average-rating....

I've read that doc and other warnings about reverting a merge. But I've found that if you revert the revert, then you avoid the problems they mention. I guess the worry is that you still have to remember to do that, or you'll

Really appreciate everyone's replies! A related question about my example: what if I want to assign the pointer dereference to `tmp` to improve readability (rather than avoid multiple traversals). Is there any reason not to use a tmp

Does anyone have any advice on articles about C compiler optimizations in general (especially gcc)? I'm doing my first serious C work in ten years, and I keep wondering if I should fuss with things like this or let the compiler handle

42% of rejections are for "other reason"--wow. No wonder people feel Apple reviews are capricious.

One thing I heard once that has stuck with me: When you earn a dollar, you pay 30-40% tax on it, but when you save a dollar, you keep the whole thing. It pays to push on both the revenue side and the expense side, but one pro of putting eff

I saw the title and thought, "Oh good, someone else who thinks like Dijkstra!" Oh well. :-) I feel like the halting problem and Godel's theorem imply programmers will never be out of a job, and the best we can do is build out

Random question for the type experts out there: is there any language that lets me track the units of my numeric variables? For instance, something like this: float<km> drop(float<m> x0, float<s> duration) { fl

I'm a huge fan of window functions, but one restriction surprises me: in Postgres, you can't put a window function into a WHERE clause. Does anyone know if there is a good reason for this, or is it just a bit of missing functional

I'm delighted to see a Ted Dziuba post! I'm very sad his posts criticizing Node disappeared. I never decided whether I bought his argument, but I thought they were valuable contributions to the discussion about the event-driven mo

Here is an exoskeleton for babies, albeit not quite for newborns: http://www.newbornbabyzone.com/wp-content/uploads/2010/05/ba... But I believe these are discouraged nowadays for slowing development.

OT question: I was playing with some C over the weekend (not C++), trying to figure out how to handle Unicode in a way that would work on Mac, Linux, and Windows. Despite a couple hours googling and reading, I couldn't answer really ba

I really admire the humility of his wait-and-see attitude, especially since he is trying to keep an open mind against his instincts. This is a bit OT, but it seems like Angular apps have similar problems to distributed objects, where you ca

This makes me think it'd be handy to embed git into a desktop application and use it as the datastore. But I suppose the GPL prevents this unless the app is open source.

I learned a lot from reading the GOF book two or three years into my programming career. I think like most people, I'd already invented a few of its patterns, like pluggable Strategies, but it was great to have shared names for things.

Okay, I was curious enough I got out my paperwork. Looks like my origination fee was a lot higher. But my closing costs also included lots of escrow for property taxes and homeowners insurance, and I guess it makes sense to leave that out.

I was able to enter just "Portland, OR" and move on. If that is sufficient, maybe the labeling could be clearer?

I just bought a home a few months ago, so I went through your process to see what results I got. It offered a 30-year loan at 4.0%. Is that really possible? It also quoted me $2900 in closing costs. I think my actual closing costs were more

I also took a few Harvard Extension School classes (mostly Greek and Latin, but also Distributed Computing). I didn't earn a degree, just took a few things that interested me. It's on my resume as Harvard Extension School, and I h

Harvard Extension School is an adult education program, like night classes. Your teachers may be Harvard faculty (but never were in the 7 classes I took there), and the other students are not Harvard undergrads. Also there is no application
