I'll take Mercurial over git any day for all the reasons obvious to anyone who's really used both of them, but geeyah github sure makes contributing to projects easy. At work we had a ten minute MongoDB upgrade downtime turn into two hours, and when we finally figured out what deprecated option was causing the daemon launch to abort, rather than grouse about it on Twitter (okay, I did that too) I was able to submit a one line patch without even cloning down the repository that got merged in.

I just rebuilt the ry4an.org server, and as part of the migration I realized a still had a lot of very old, almost embarrassing content online. I took the broken or not-conceivably interesting stuff off-line and am serving up 410 GONE responses for it.

There exists, however, a broad swath of stuff that's not yet entirely useless, but is more than ten years old and not stuff I would likely post today. For all of these pages I've left the content up, but you first have to click through a modal dialog warning you you're looking at very old stuff I don't necessarily endorse. That pop up looks like this:

The Python logging module has some nice built-in LogHandlers that do network IO, but I couldn't square with having HTTP POSTs and SMTP sends in web response threads. I didn't find an asynchronous logging wrapper, so I wrote a decorator of sorts using the really nifty monkey patching availble in python:

def patchAsyncEmit(handler):
    base_emit = handler.emit
    queue = Queue.Queue()
    def loop():
        while True:
            record = queue.get(True) # blocks
            try :
                base_emit(record)
            except: # not much you can do when your logger is broken
                print sys.exc_info(
    thread = threading.Thread(target=loop)
    thread.daemon = True
    thread.start(
    def asyncEmit(record):
        queue.put(record)
    handler.emit = asyncEmit
    return handler

In a more traditional OO language I'd do that with extension or a dynamic proxy, and in Scala I'd do it as a trait, but this saved me having to write delegates for all the other methods in LogHandler.

We just passed through another graduation season, and for the second year running I was able to get by with the same stack of form letters:

Dear _______________________________,

My ( Congratulations | Condolences | ___________________ ) on your recent (
Graduation | Eagle Rank | Loss | ___________________ ).  It is with ( Great Joy
| a Heavy Heart ) that I received the news.  I'm sure it took a lot of ( Hard
Work | Cigarettes ) to make it happen.

I'm sure you'll have a ( great time | good cry ) at the ( open house | wake )
and ( regret | am glad) that I ( can | cannot ) attend.

As you move on to your next phase in life please remember:

[  ] the importance of hard work
[  ] the risks of smoking
[  ] there are other fish in the sea
[  ] don't have your mom send out your graduation invites -- you're an adult now
[  ] ________________________________________

and the value of personal correspondence.

Sincerely, your (Cousin | Scoutmaster | Parolee | _____________________),

The University of Minnesota has a Scholar's Walk which celebrates great persons affiliated with the U and the awards they've won. One display labeled "Historical Giants" remains without any names. Since the U can't reasonably be anticipating any new history, I imagine that four years after installation there's still a committee somewhere arguing about which department gets more names. Not content to wait for committee I decided to add a historical giant of my own -- a time traveller.

I just made my third batch of tonic water from Mark Sexauer's Recipe:

• 4 cups water
• 4 cups sugar
• 1/4 cup cinchona bark
• 1/4 cup citric acid
• Zest and juice of 1 lime
• Zest and juice of 1 lemon
• Zest and juice of 1 orange
• 1 teaspoon coriander seeds
• 1 teaspoon dried bitter orange peel
• 10 dashes bitters
• 1 hand crushed juniper berry (I used two)

The flavor is excellent, but the process is terrible. Specifically, filtering the cinchona bark from the mixture after extracting the quinine (actually totaquine) from it is nearly impossible. It's so finely ground it clogs any filter, be it paper or the mesh on a french press coffeemaker, almost immediately. I've tried letting it settle and pouring off the liquid, forcing the liquid through with back pressure, and letting it drip all night -- none work well. A friend using the same recipe build a homemade vacuum extractor, but I've not yet gone that far.

Like half the internet I'm working on duplicating a setup from one Amazon EC2 availability zone to another. I couldn't find a quick way to do that if my stuff wasn't already described in Cloud Formation templates, so I put together a script that queries the security groups using ec2-describe-group and produces a shell script that re-creates them in a different region.

If all your ec2 command line tools and environment variables are set you can mirror us-east-1 to us-west-1 using:

I'm a huge fan of the Khan Academy (and if you haven't yet watched Salman's presentation at TED2011 you should go do that). I'm involved (slightly) in an effort to bring Khan Academy instruction to a local school district and have a standing offer to "coach" participants. Today, though, I found a use for the Khan Academy site probably doesn't endorse: dealing with online panhandlers.

Before today I'd never seen an IRC panhandler, email sure, but never IRC. This morning, though, someone wandered into #mercurial asking for money to renew a domain. Most people ignored the request since it's grossly inappropriate in a software development work space, but I offered the kid the money if he'd do algebra problems on the Khan Academy site.

I've had a resume in active maintenance since the mid 90s, and it's gone through many iterations. I started with a Word document (I didn't know any better). In the late 90s I moved to parallel Word, text, and HTML versions, all maintained separately, which drifted out of sync horribly. In 2010 I redid it in Google Docs using a template I found whose HTML hinted at a previous life in Word for OS X. That template had all sorts of class and style stuff in it that Google Docs couldn't actually edit/create, so I was back to hand-editing HTML and then using Google Docs to create a PDF version. I still had to keep the text version current separately, but at least I'd decided I didn't want any job that wanted a Word version.

Tonight I tried Hirelite, and I really think they're on to something. They arrange online software developer interview speed-dating-style events where N companies and N software developers each sit in in front of their own webcams and are connected together for live video chats five minutes at a time. It's like chatroulette with more hiring talk and less genitalia.

They pre-screen the developers to make sure they're at least able to solve a simple programming problem and screen the companies by charging them a little money. Each session has a theme, like "backend developers", and a geographic region associated with it. After each five minute interview -- there's a countdown timer at the top -- each party indicates with a click whether or not they'd like to talk further. Mutual matches get one another's contact information immediately afterward.
