ECS A785GM-M

FYI, The ECS A785GM-M 1.0 does *not* have a speaker connector. Makes it difficult to have a system beep without the built-in speaker.

Databases and backups

Yesterday, I managed to delete the primary database that we use at work. I won’t go in to how this happened, other than to say: Fuck you MySQL Workbench. I was trying to get a map of the table relations within the database. Needless to say, it didn’t work. After the immediate pants-wiping, I restored the database from the backup. But the backup was from the previous morning, as the current backup hadn’t finished. Unfortunately, I couldn’t find the files from the mornings backup.

In short, losing data sucks. How often do database “pros” backup their data?

How to fix strange characters in MySQL database – Vinh Pham

dp — Tue, 26 Jan 2010 22:15:06 +0000

I admit, I borrowed this from How to fix strange characters in MySQL database – Vinh Pham. But I also added a few more that were missing;

update

 set  = replace(, 'â€™', '\'');

update

 set  = replace(, 'â€¦', '…');

update

 set  = replace(, 'â€“', '-');

update

 set  = replace(, 'â€œ', '"');

update

 set  = replace(, 'â€', '"');

update

 set  = replace(, 'â€˜', '\'');

update

 set  = replace(, 'â€¢', '-');

update

 set  = replace(, 'â€¡', 'c');

update

 set  = replace(, 'â„¢', '™');

update

set = replace(, 'Â®', '®');

Hopefully this helps someone (probably even me) sometime down the road!

Cleaning up bad data in an SQL database

dp — Tue, 02 Jun 2009 19:13:16 +0000

Recently, I needed to find all of the data in a table that was being used for HTML output, that had non-printable characters. The following SQL statement should do that for you:

select id, name
from table_name
where name not regexp '^[a-zA-Z0-9_ ,&;\/<>(²):%*#?$|!+.\"\'-]+$;

This code is MySQL specific, but should be applicable anywhere, really.

I’ve been working on getting all of the sites on which I have public profiles compiled together into a list. Currently, the fruits of that effort can be seen in the sidebar of this site. All of those urls should have a rel="me" attribute on them, so that the social graph is correct, and all of the things that I’ve done can be properly attributed to me.

In the process of this, I’ve been working on a script of my own, to generate this graph. I’m using Perl and GraphViz to generate it. Right now, it’s about 2MB of PNG, which still needs some work.

I’d really like to fix it up a little, fixing the edges to be properly bidirectional, using a bit less space as fluff, and potentially adding in my contacts/acquaintences/etc.
