Saigon MobileDevCamp 2011

Submitted by tomo on November 8, 2011 - 2:16am

This past weekend was the third annual Saigon MobileDevCamp held at Bach Khoa University. Although I'm mainly a web developer, as the event was billed as a brother to BarCamp, I decided to go and check it out, meet some people, support my friend Dan, and see if anything from the event could be applied to the upcoming BarCamp Saigon on December 11th.

Like BarCamp, the venue is a local university. However, the quality of facilities between a regular Vietnamese university like Bach Khoa and a foreign-operated campus like RMIT are on a quite different level. Most rooms were without air conditioning and became quite hotter than I'm accustomed to. In the morning there were a number of sessions on developing mobile apps (I checked out a session on PhoneGap but missed the Unity 3D session). In contrast to the BarCamp ideal, guest speakers were invited to give sessions which were planned and scheduled beforehand. Topics were confined to the "mobile development" theme.

After lunch, the main event would be a 24-hour coding competition. As I was already waking up far earlier than usual to attend the conference which I hadn't even properly registered for, I had no intention of joining the hackathon but I would eventually be overcome by my friend Cong's excitement for Doing Things.

So that's it. We lost. We learned some lessons.

1. Be one of the first to present if you can.

2. Don't single out and alienate judges.

3. Don't build clean, well-architected software with maintainable code. In real life, this matters. For this competition, it doesn't.

The greatest tragedy perhaps (besides not winning) was that the presentations were all made in private with the judges. Having groups present their apps for everyone to see, or at least putting them somewhere online, would have been the BarCamp way. As we didn't receive any feedback or anything from the judges, it would have been nice to share what we all worked on for 24 hours (multiplied by nearly 100 people) and be able to learn from others' experience. Even if there wasn't time for all to present, I don't think I was the only one interested in seeing at least the demos from the winners.

AutoMySQLBackup

Submitted by tomo on October 9, 2011 - 1:09am

I'm using AutoMySQLBackup v2.5 and haven't upgraded to v3.0 because the new version splits out config from code (nice) but also expects you to put everything in /etc (not nice). It's a fairly simple script made complicated by this new version which even includes an installer script now, which is more reason to keep with the old version.

Some changes I made:

OPT=" --quote-names --opt --skip-lock-tables"

I'm running this script out of cron and I don't want to lock tables which the web server is serving, even if it means some rows will be out of sync.

Then I change all "rm -fv" to "rm -f" because OpenBSD rm doesn't have a "-v" option, which if my assumption is correct means "verbose" and it's not useful in this script.

Since my databases aren't so small anymore, I've had to set MAXATTSIZE="20000". I also want to filter certain tables (big ones that never change, cache and log tables) and AutoMySQLBackup 3.0 has a new setting CONFIG_table_exclude for this.

The section of new code that does this is:

    if ((${#CONFIG_table_exclude[@]})); then
      for i in "${CONFIG_table_exclude[@]}"; do
	opt=( "${opt[@]}" "--ignore-table=$i" )
      done
    fi

In 2.5 we can add these tables manually to the OPT variable after the "
OPT" line, e.g.

$OPT="$OPT --ignore-table=foo.bar --ignore-table=foo.baz"

This saves a lot of disk space and space in my Gmail account used for storing backups.

Having just gone back to the United States for a week, here are some reasons why I no longer live ther. I didn't move abroad because of these reasons, but now that I'm living in Vietnam, these are some of the reasons why I won't move back.

1. Lawn-mowing. I'm allergic to not only the job of mowing lawns and the grass clippings and plant matter that gets tossed into the air, but now the sound itself puts me on edge. Somehow all the dust in the air and sound of motorbikes in Saigon doesn't have the same effect.

Twitter Decoder Ring

Submitted by tomo on September 5, 2011 - 3:17am

My latest Chrome extension is a quick wrapper around a "service" (hoping the provider see it that way :) to compress English text and get around the 140 character bound on Twitter.

Twitter Decoder Ring: https://chrome.google.com/webstore/detail/idcnolgflhcckjdfpfbcehjocggffdjk


Twitter has a 140 character limit on tweets. This can be annoying when you are writing something and end up just slightly over (seeing negative character counts). So a lot of third party solutions have sprung up to allow one to tweet longer tweets by basically linking to a blog post. For example, TweetDeck does this. There is a way to compress some 140 words into 140 characters by 1) using the set of Chinese characters to represent bits and 2) compressing the English text into as few bits as possible.

For example, the entire paragraph above compresses into this non-sensical Chinese character string: 顜善嬔巖嗴允曏不t唈吷呈 呌噑庠嗱鲷凸亥丂仨丶乇儓乓(劗揦允圫s囸 严懦倡侭鹔丘柺槐嫢忒爠t唈堺倱t唈婐丕珹埼円七哢蠧呕囫 自t唈吷讴鏞弣恟帺呙冑咭巖嗴佽哻巖0簝噯呝丕1哼测樖匡螎諑歘丂2哼檂鎗俫抆哻与亩歘挍叜

I have always thought it a bit unfair that Chinese Twitter users get to say a lot more in 140 characters than we English-speakers do, because each Chinese character essentially represents an idea and often a complete word, rather than just a sound in an alphabet (like the Latin, Arabic, Hebrew, or even Vietnamese alphabets). On the other hand, Chinese Twitter users aren't allowed to access Twitter so I guess it's a draw.

A description of the project to compress English words into Chinese characters is found at: http://thevirtuosi.blogspot.com/2011/08/tweet-is-worth-at-least-140-words.html and a web frontend for the Python script that does the compression can be found at http://pages.physics.cornell.edu/~aalemi/twitter/

It's important to note that although the characters are real Chinese characters, the string that is created most likely isn't correct or meaningful Chinese when read by a Chinese person.

This extension uses the backend from the above blog post and provides a quick and dirty wrapper to encode English text as compressed Chinese characters.
