Just a quick note: Don’t even think (really, no kidding!) about doing the remote installation via W-LAN (at least with if you can’t use 802.11n). Even with Gigabit Ethernet it takes ages:
(Doesn’t look too bad, huh. But: the estimated time remaining is steadily counting up, not down.)

Yes, I am alive. It’s more than a week now that Snow Leopard came out and there is still no new version that works with the new Mac OS X. The reason is simple. Instead of using the time to fix the old Seafoid I’ve started to completely rewrite the app from scratch to make it more extendible for future development. It will also come up with some cool new features. Just to name a few:
- Calculating circuits with the legendary NE555 (currently as an astable and monostable multivibrator)
- Revamped heat sink calculation. Additionally to the old way (calculating the resulting chip temperature for a heat sink), Seafoid has a new option called “Calculate Appropriate Heat Sink” where you specify the maximum chip temperature and the app will tell you what thermal resistance the heat sink must have.
- Seafoid 3.0 combines the clean look of Seafoid 1.x and the function of Seafoid 2.0, plus lots of improvements and new features.
- Seafoid is now localizable! The beta release will come with English, German and Greek translations.
- Lots of minor improvements like better input information and exception handling.
A beta version will be available soon is available. Stay tuned!

There’s a thing that I experienced on two different Macs (Late ‘06 MacBook and Late ‘08 MacBook Air, both 10.5.7) at the same time: Software Update caused the whole system to hang after I had chosen to install the updates. No app would launch anymore, even a shutdown wasn’t possible.
Deleting /Library/Preferences/com.apple.SoftwareUpdate.plist did the trick and everything’s fine again.

I was a bit lazy recently when it came to coding apps. But there is something to come: a graphical user interface for sispmctl. This allows you to control USB-controlled power outlets. That’s how far I’ve come:

The final version is going to feature triggered switching (for example: turn on external HD when Final Cut is launched) and scheduled switching. Beta soon.

Microsoft Internet Explorer (at least versions prior to 7) seems to have some annoying bugs concerning lists in HTML.
- Problem: Margin between list items (”li”). If you set the margin of a list item to 0px in CSS, IE will still show a gap between the list items.
Fix: Set a width for the list item (”li”) and the list itself (”ul”, “ol”). 100% will do the trick in most cases.
The margin issue is fixed by this but it leads us to the next problem:
- Problem: When you set a width for a list item in an ordered, that is, numbered list (”ol”), Internet Explorer won’t count properly anymore.
Fix: I don’t know any.

I wanted to display the titles of recent blog entries on my start page.
Here’s the solution I came up with:
<ul id="recent_entries">
<?php get_archives('postbypost', '5', 'html', '', '', FALSE); ?>
</ul>
'5' specifies the number of posts to be displayed.
Just a little CSS styling for the list (#recent_entries li {...}) and that’s it.

A thing I just discovered when doing the new design for seafoid.org:
If you have a div that acts as a container for floating divs, it won’t grow with them.

The trick is the following: insert this piece of code to the CSS of the container.
overflow: auto;
width: 100%
The width attribute is necessary for Internet Explorer versions prior to 7.
Hope that helps.
