Indeed. MacPorts has the additional advantage of using upgradable and removable packages, rather than polluting /usr/local (or worse, /usr) with unmaintainable detritus of various .pkg installers. MacPorts packages do occasionally fail to b

Clean, but what are you supposed to do with user agents which do not support JavaScript? Server-side templates still let you customize the page in that case.

I've looked at AllegroCache before, and really liked it. Can you briefly discuss how a graph database of type you describe (AllegroCache or KiokuDB) differs from the object-oriented databases which have not exactly taken the world by storm?

Dylan started with an s-expression syntax. For several years, it looked like Scheme with CLOS bolted on top. The language eventually switched to a conventional infix notation. It actually looks pretty good to my s-expression-addled eyes, ex

With regard to web apps, you ask a big question, which I, for one, am unprepared to address in a brief comment. In general, however, functional programming aims to make it easier to think about what a program does as it runs. In imperative

Interesting. So you had a SQL Server instance, paired with a failover backup on hot standby (using Windows clustering), serving up data from a bunch of disks attached together in a SAN, right? Which SAN products did you use, and how much di

That sounds terrific. Please provide more details about the setup you used. Which database product? Does that product support splitting tables across multiple servers? Does it let clients transparently query across all of them? Which featur

Of the embedded databases I'm familiar with, Berkeley DB with its transaction layer does support multi-process access. It requires some careful coding but does work and detects deadlocks of the type you describe ( http://www.oracle.com/tech

So the primary reason for moving stuff out of the database in this particular example is not performance, but storage constraints. Relational databases are notorious for being exceedingly difficult to scale beyond a dataset which fits on on

S3 does this for a living. I don't. So does Carbonite, and, as you can see in today's news, it also lost people's data. I strongly suspect Amazon does a better job than Carbonite with both software and infrastructure, but still. Mistakes

I personally like "From Bash to Z Shell: Conquering the Command Line." It focuses somewhat more on zsh (my shell of choice) than on bash, but one of the authors contributes heavily to zsh. Even so, bash users will see lots of great hints an

Sounds impressive and cool. I wonder about Table engine performance though. My experiences with Berkeley DB (using the native C API) were positive, from a performance point of view, largely because BDB has no built-in query support. When

I don't understand why people keep trumpeting this like it's a big revelation. Because the dependency on entry order makes the div's class semantically meaningless. Yes, the order in tables makes a difference, but in a table, that makes s

Looks like the Esc-. trick works in zsh as well. I didn't know about it. Cool. Thank you. With regard to pushd and popd: these tricks work in zsh also. In addition, (again, zsh-specific) you can set these options: setopt auto_pushd

I totally disagree. I consider links here recommendations for good reading. If the discussion is not as in-depth as you might like, think of it as a set of informal reviews and opinions, probably more reliable than the ones on Amazon.

I read somewhere that ties cover up the buttons on a shirt. So while uncomfortable, silly-looking, and a tool for strangulation, they serve a purpose. Jackets, on the other hand, are completely absurd. With the lapels turned outside by the

Early in the article, the author says that a card is something you have, a public identifying token, and, since it can be stolen, it should require something to unlock it. Later, in the hospital example, he suggests that a private key store

I'd like to hear an answer to this, too. Could it be the magnification? Basically, do these things just work like very low-power reading glasses (say, +0.25)?

The author made this out-of-print book available on his site ( http://www.nobius.org/~dbg/ ). I was looking for information on how filesystems work, and stumbled on this. Since I've heard the Be filesystem described as "a marvel," this look

It takes more than 20 seconds to install a keyboard layout switcher on an unfamiliar Linux distribution, or, for that matter, on a poorly-set up Windows installation. Also, if you just need to type for a few minutes on someone else's machin

According to news reports about him, Chesley Sullenberger is an excellent pilot. Yesterday's Times article about him ( http://www.nytimes.com/2009/01/17/nyregion/17pilot.html ) says that he won the Outstanding Cadet in Airmanship award when
