If we're being picky then you probably also want `mkdir -p -- "$1"` in case they want to create a directory named `-m`, `-v`, etc. Surprisingly `--` isn't mentioned in the mkdir manpage on my system, but it works. E.g. `

Thanks for your work on munin. I love it! And I appreciate your responsiveness here. Personally I don't care if my server wastes time generating HTML I never see. It's not enough work to make any difference. But I care a lot about

Munin is my favorite monitoring tool. One reason (among many mentioned here already) is that its information density is higher than anything else. When your site goes down and you need to know why, the page full of tight graphs is incredibl

Having good COGS data is also helpful within a business to measure the profitability of different products: e.g. one brand vs another, or shirts vs pants. But it's one of the hardest things to measure. Partly that's from the imp

Wow there are some cool tricks here! In Firefox any objects you pass to console.log are expandable, so you can say console.log("my hash", h). It seems to behave the same when you say console.log("my hash %o", h). But the

Running your own Postgres is surprisingly easy, even with backups/monitoring/replication. Postgres replication has a reputation for being difficult to set up, but that's not what I've found. I think the reputation largel

A few years ago I took a printout of Fong & Spivak with me on vacation to Greece. I really enjoyed the first few chapters---and my wife got to make fun of my leisure reading choices. :-) I wish they sold a bound copy, because at home am

So could you use this to implement always-up-to-date materialized views in Postgres? It says it uses relational data for inputs and outputs. It says it operates in-memory but also that it starts up from a set of known facts (which sounds li

Let's not let that be an excuse to settle for poor security, either from Github or our banks. I agree the way Plaid/Yodlee/etc ask for passwords is insane. I've "closed the tab" several times when I hit that. J

As a non-physicist, I've always been hung up on a much simpler paradox: how does radiation escape from a black hole? I thought even light could not escape? Is there an explanation to that?
