Since most of the comments are critical, I'll say: thank you for the awesome writeup! I agree this is more complex than HA PG setups I've done in the past, but I'm thrilled to have another perspective. Also doing a thorough w

Ironically in the context of the original article, it's precisely when you're trying to support IE 5+ or 6+ (or even more modest goals) that less/sass is really valuable, since you can generate chunks of CSS values with all t

I think for all of us it is a lifelong struggle, but here are some things I do: - If I'm stuck I take a walk. - Tackle the hard/unknown/risky stuff first. - Do the boring/easy stuff after lunch when I'm sleepy. - Th

The sidekiq ruby gem ( https://github.com/mperham/sidekiq ) is a good example of a small open source project that earns a living for its author, Mike Perham. He sells licenses to a closed-source version with some enhance

Thanks! After reading this [0] I'm surprised that my high school recollection seems to be how it really works. It still seems very strange. One thing in that article bothers me though: it talks about the wave itself as vibrating, e.g.

I've never understand the idea that in non-polarized light, the "amplitude" of the light wave points in all directions, whereas in polarized light it points in only one. The amplitude of a light wave doesn't literally me

Assuming I wanted to pick up COBOL and land a contract gig, what else do I need to know? A language is syntax but also libraries, patterns, and ecosystem. For instance it's hard to do Rails without knowing Git, Bash, Linux, SQL, Javasc

Definitely agree re bulk inserting, say every 1 minute or 1 hour or whatever. I was paying around recently with Amazon's Kinesis for this, but if you don't want the vendor lock-in you could easily roll your own system that bundles

I think what mason had in mind, which I agree is a major pain point, is when a central table "owns" records in other tables, e.g. a `book` might have several rows in `pages`. I want to say "give me edition 3" and get not

There was an effort to build bitmap indexes for Postgres a few years ago. There are details in the mailing list archives. It looks like it was almost completed! It's high on my list of things to tackle if I ever get time to start contr

I have a buddy with a rack in his garage he uses to run proxmox and asterisk. I suppose you could also run your own SMTP server for private email. Those are some things that seem like they'd be compromised by renting a VPS. I'm as

That is the normal pattern in Rails apps using the `acts_as_paranoid` or `permanent_records` gems (`deleted_at` to match `created_at` and `updated_at`). But I often also have `deleted_by_id` to capture Who, and I wonder if I shouldn't

Aristotle wrote that laws are for the general case and judges for the specific. In other words, they are guidelines but you want a human to interpret them and apply them to a concrete situation. Hence "hard cases make bad law." An

It seems like you are the one speculating . . . about the author's credentials. Also, the fact that thinking includes computation does not imply that computation includes thinking. There is a strong case that the brain is a computer, b

I hit the issue with blocking log IO all the time, not because of ^S, but because I develop in tmux and hit ^A[^B^B^B to read some stack trace (my ^A is tmux's ^B), then Alt-Tab to the browser, hit ^R, and it just spins. Then I wack my

Yep, I've hit this in Perl and Ruby and even once wrote a class to do something like Python's `communicate`. It's especially trappy if you want to run a command and both send stuff to its stdin and read stuff from its stdout.

Today's code schools may be new, but not code schools in general. Riding on the T in Boston 2000-2005 I saw plenty of advertisements for courses in Java, XML, etc. I always assumed those were low-quality classes for low-quality program
