`hstore` is good if you know for sure you'll never have nesting (because the values have to be primitive types). Otherwise, JSON is probably the safer, more reliable bet, though it's slightly slower.

This sounds like heresy, but you can actually use Postgresql. It has a JSON column type that supports indexing! http://www.postgresql.org/docs/9.4/static/datatype-json.html

This is a really neat idea -- essentially, outsource your web of authority to a third party. Given that it (apparently) only takes around 300 followers to crack the top 1,000, I wonder how long it's going to take for gray-referrer serv

This was a great investigation of what must surely have been a complicated, frustrating, and expensive problem. Awesome writeup. I love reading about post-mortems like this, even if they're unlikely to happen at my startup, because the

They can definitely be both! But the function of a UI is not to be "gorgeous" -- it's to be usable . A UI that's entirely functional without being flashy or visually attractive still accomplishes its mission (e.g. space

Instead of creating "gorgeous" UI, shouldn't we be creating usable UI? Just because something is wonderful to look at in no way guarantees that it's functional or usable. I feel like these articles miss the point that

I'm not saying that any of the stuff suggested can't be done with git. The point is that this is not the use case git was designed for, so it doesn't accommodate it easily -- you must write all the exceptions and special case

Here's a very obvious use-case: You have a single file with many historical changes. That file moves to a new directory that is not a subdirectory of its current directory. In git, the file vanishes from the repo and can't be trac

It would pretty dumb of them to take this step and then pick a license which wasn't permissive enough to make it happen. Plus, given that they mention they're working with the Mono team on this, I'm sure they're going to

Open-sourcing .NET doesn't magically make it work on other platforms (a not-insignificant chunk is Win32-specific, for example). But it certainly makes the Mono team's job easier.

Not if the arrests are thrown out more often for one group than another. The police can arrest anyone, but that doesn't make it a legal arrest.

We do. In the report from the above article, the arrest rate was similar for blacks vs. whites. If the arrest rate is similar but the stop rate is disproportionately larger that is a pretty strong suggestion that something is amiss.

It's measuring percent, not percentage points. 38% is ~34% less than 56%, but about 18 percentage points. If your risk was lowered from 2% to 1%, that's a 50% reduction, but a 1 percentage point reduction.

The timing of this seems odd to me. Why now, of all times? Is Inspeqtor getting too big or stealing too many Monit customers? It's also a little strange that the tweet Monit references as being demonstrative of intent happened six mont

Just to be clear, it was $250 to $1,000 per hotspot/AP that they were charging, not per device. (That is, if your convention needs 3 hotspots, presumably you would pay $750 to $3,000, no matter how many people connected.)

A regexp would work, but it's usually the wrong level of abstraction to operate at. One wants to say "for the next 2,000 rows, retrieve columns 2 and 4, and the column labeled 'foo'", not write a regexp.

I don't think they care so much about preventing encryption --after all, you can already encrypt your iPhone or Android device, if you really want to. What they're much more concerned about, IMO, is that this could now be the _def

This is true, and is a good counterexample to my point since I do use these on an everyday basis.
