Sometimes we say something that sounds right but is in fact the exact opposite of what we mean.
So it’s entirely possible that a talk you started presenting a year and a half ago is so different now as to be almost indistinguishable from the original.

In some of my Rails projects, I have been a contented user of the memory_test_fix plugin. However, I rather dislike the use of Rails plugins, because I find updating them later on rather difficult, and I don’t like including external libraries in my own source tree (hence, I don’t like the practice of vendoring gems much either). When the concept of ‘gem plugins’ was introduced, I created a fork on github and created the necessary files to build the plugin as a gem, and have Rails properly load it.

You can implement a programming language in assembly. C is an example. This has the advantage of being able to leave your language and use assembly when necessary. You drop down to assembly for speed.
You can also implement a programming language in lisp. CLPython is an example. This has the advantage of being able to leave your language and use lisp when necessary. You drop down to lisp for expressiveness.
If lisp is the ultimate language, does this not make it the best option for implementing other languages?

Because URL shortening services can go away at any time, I decided to install my own. In the spirit of your-own-dogfood, and to make hacking it as enjoyable as possible, it had to be in Ruby (this ruled out YOURLS, which otherwise does exactly what I want). There are tons of URL shortening projects in Ruby on GitHub. Unfortunately, they all lacked one feature: password protection for the adding of URLs. In the end, I picked a nice simple one and changed it to my liking. The result can be found in my fork of turl.
Why is this safer than using one of the existing services? The reason tr.im went under is that they couldn't make it pay for itself, and there was a lot of abuse from spammers. Both problems are absent for my own service: I don't need to make any money off of it, and I'm the only one who can create new short URLs.
Some observations on developing this software:
For a small project like this, putting everything in one file is very, very nice. Ramaze allows you to do this (as do other frameworks), Ruby on Rails does not. I wonder how seamless the transition is if your project starts small like this and then gradually becomes big enough that you need to split it into different files.
Ramaze's documentation needs some love. Everything is documented well in
principle, but with the split-off of the innate library, it took me
ages to find the documentation for the a method and friends.
I really like the idea of [Sequel][sq]::Model where you define the
table schema right in the model. I'm not sure how or how well it works
with migrations, but for a small project like this, it's nice and clean.
Ramaze could use some more options for session storage. In particular, something file-based shouldn't be too much to ask for. I'm using the LocalMemCache option, and keep having to log in.
I really like Ramaze, and am eager to try Sinatra. I have been ignoring these more light-weight frameworks for far too long.

Daring Fireball quotes Zeldman:
Flash won’t die tomorrow, but plug-in technology is on its way out.
Exactly. And good riddance.

Today I got an email from someone using a hotmail account. At the bottom was the following text:
Hotmail: Trusted email with Microsoft’s powerful SPAM protection. Sign up now.
The text “Sign up now” links to a URL that is completely opaque. Not in the old-style non-Web-2.0 company website way, where at least the domain name would tell you it’s a legitimate link to one of the company’s websites. No, it’s domain part was clk.atdmt.com.
If we/they/whoever expect people to click such links, how can we ever expect people stop clicking links like http://hotmail.com.xdfsf.cn/please/hack/me/totally?
It’s almost as bad as training people to give their email login and password to any site that asks them to.

Learning about monads is hard, and there seems to be no magic pill. Probably one reason is that they have several different uses. Many articles focus on one of those uses, making it hard to get the whole picture. On the other hand, articles that try to directly explain what monads are leave the reader wandering what they're good for. Some links.

You have been running a Typo blog [since 2005][since], but you still can’t quite get your Apache configuration right. In particular, you still get the occasional

We recently returned from a trip to visit Naoko’s parents in Tokyo. We took lots of pictures. Here are some of them.
A nice bowl of ramen with creamy broth, crunchy bean sprouts and delicious soft pork. I love ramen.
A wedding at Meiji Shrine. We went to the shrine during Shichi-Go-San, so there were lots of little girls and a couple of little boys all dressed up in kimono. Our daughter, having just turned three, was one of them.
Of course, it is the season of beautiful autumn leaves. It is actually quite hard to capture the beauty of these maples.
This picture of a female Nephila clavata spider was taken near Chichibu. This one measured about 6 or 7 cm diameter (including legs). One of the locals told us that they let the spiders fight each other for entertainment. Of the locals, that is.
A pile of small raw octopus at the famous Tsukiji fish market, which I finally managed to visit.
