tech notes and general nonsense
Setting access control list(acl) recursively is not as straigthforward in HP/UX. I believe the same is true for other Unix flavors. In case you are wondering how, the command is shown below.

The default screen capture of Mac, command+shift+4, is good. I can specify the part of the screen I want to capture and it’s automatically saved into a PNG file. It’s very simple and straightforward. But the longer I use it, the more I miss Greenshot. But that’s not (yet?) available for Mac.

Mac OS X already comes with the Disk Utility app which you can use to burn ISO images into a CD/DVD. You don’t have to buy or download a new app to just do that. The step-by-step procedure is shown below.

I have a script that needs to be deployed in different environment as most scripts are. This script requires asking for userid, tnsname and password during deployment. I tried to use READ but it echoes the password on the screen as soon as I type it. So how can we hide the password? Here’s how.

I only realized this last week that direct update of the last number of the sequence. Or maybe I just don’t know so what I did was to create a workaround.

To prevent spam comments on one of the sites that I maintain, I send for approval any comment with at least one URL or email address in it. In that way, manual spammers will find no incentive on leaving comments on the site. At the same time, email addresses left by commenters will not be displayed in the site until it is sanitized. However, the amount of comments in the site in question is so many and manually sanitizing comments with emails is becoming a pain.

I use the terminal a lot be it in Mac, Windows or Linux. And it’s kinda frustrating in Mac for the lack of a dedicated insert key. Clearly, you’ll never think about small things until it’s gone. Copy-Paste function turned out to be an important feature.
So I looked for the equivalent command/key combination in the net and the combo below worked on MacBook Pro.
fn+command+v
Yeah, I know it’s a kinda bummer because it’s just one key on PC( Windows, Unix and Linux). But that’s how Apple is. Also, I’m not sure if it works for iMac. I heard there’s another key combination.
For some reason, the code being generated inside Facebook developer does not work. Actually, the problem is on the profile_id parameter which is not recognized by the likebox.php. Instead, id should be used.

If still that doesn’t work, then you can use the legacy code as below.

I tried both and they all worked as expected.

I recently upgraded my MySQL in preparation for WordPress 3.2. The version I now have is 5.5.12. The upgrade finished without a hitch but when I tried to restart the service, the MySQL Daemon failed.
Here’s the log of mysql (/var/log/mysqld.log)
110514 14:04:22 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
110514 14:04:22 [Note] Plugin 'InnoDB' is disabled.
110514 14:04:22 [Note] Plugin 'FEDERATED' is disabled.
/usr/libexec/mysqld: Table 'mysql.plugin' doesn't exist
110514 14:04:22 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
110514 14:04:22 [ERROR] Unknown/unsupported storage engine: InnoDB
110514 14:04:22 [ERROR] Aborting
Initially, I thought the problem was on the mysql_upgrade part because that’s the first error that appears on the log. Apparently, that’s just a warning message because the service still managed to proceed to the next step which is for the InnoDB. And based on the log, it failed to start and actually aborted. So that’s where I should concentrate my investigation/trial-and-error.
I opened /etc/my.cnf and comment out skip-innodb and then restart mysqld. It fixed the problem and mysql managed to start. I then proceeded with the mysql_upgrade which is unrelated to the error.
Another solution for this is to set the default storage to other than InnoDB. However, I haven’t tried that myself.
I wanted to try WordPress 3.2 beta but realized that it requires at least PHP 5.2 and I’m still with 5.1.6 (the one that comes with CentOS). Here’s what I got from the interwebs.
Step 1: Get webtatic PHP 5.3 Repository
rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
Step 2: Update PHP
yum --enablerepo=webtatic update php
Step 3: Verify PHP version
php -v
Expected result should be like below
PHP 5.3.6 (cli) (built: Mar 19 2011 08:30:07)
Copyright (c) 1997-2011 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies
*** NOTE ***
Though webstatic stated that the repository is created for CentOS 64bit, it still worked for my 32-bit installation.
