Beating PostgerSQL 8 Into Submission on OS X 10.5 Leopard
Filed Under Computers & Tech on December 19, 2007 | Leave a Comment
In general the move to Leopard has been very smooth for me but there was one notable exception, getting a working PostgreSQL 8 sever up and running on my MacBookPro. A few weeks ago I’d expended a lot of time and effort on this and gotten nowhere so at that stage I’d decided to work around the problem by using a remote PostgreSQL server rather than running one locally. This works fine as long as you have broadband internet access. However, I’m off to Belgium for a week on Saturday where I’ll have no broadband but where I will need to get some development work done that requires access to a PostgerSQL server.
With the end of the week getting closer I had another go at getting PosgreSQL to behave on OS X and I did eventually succeed. I got 90% of the way there by following these instructions but then I ran into a few strange problem that took a little more time and effort to work around. However, the good news is that I got it all figured out in the end!

Leopard 10.5.1 Appears to have Broken My Epson Scanner
Filed Under Computers & Tech on December 10, 2007 | Leave a Comment
In one of my early Leopard posts I was happy to report that my Epson scanner was working perfectly. However, yesterday when I went to scan it wouldn’t work. It kept telling me there was an error communicating with the scanner. I checked the connections and all seemed normal. The only real change there has been on the system since the last time the scanner was used was the update to 10.5.1. I can only conclude that that’s what broke it.
Regardless of who is to blame I did eventually find a solution. First, go to the Epson site and download and install the latest drivers for your scanner, the description should explicitly say that it supports Leopard. Then reboot. It doesn’t tell you to but I couldn’t get the scanner back into life without a reboot. At this stage I found that the Epson Scan utility wouldn’t even launch. However, the TWAIN drivers themselves do work so you can scan using Preview.app. I’d never used Preview to scan before and I have to say I’m impressed with the interface. You can scan from within Preview by going to File -> Import Image ....
I have to say I’m a little disappointed with Apple over this, 10.5.1 was supposed to fix things, not break them!

More QuickLook Goodies
Filed Under Computers & Tech on December 5, 2007 | Leave a Comment
I’ve already posted about two third party QuikLook generators (QLEnscript & Folder QuickLook Plugin) that I’ve come across and like. Today I have another one to add to that list, BetterZipQL. As its name suggests this generator is released by the people behind BetterZip. It’s completely free and doesn’t require BetterZip to be installed to work. The download and buy buttons on the top right of that page are NOT for the QuikLook generator but for the actual BetterZip program. The link to download it is in the text of the article just be low the screen shot. As you’ve probably guessed this generator allows you to see the contents of a wide variety of archive file formats using QuickLook.
On a related note, there is now a 1.0 version of QLEnscript available.

Yet Another QuickTime Zero-Day Vulnerability
Filed Under Computers & Tech, Security on December 1, 2007 | 3 Comments
Apple’s security reputation takes another dent this week with yet another zero-day exploit in its QuickTime media player. There is now proof-of-concept code out there which uses this exploit to remotely compromise computers running both Windows and Mac OS X. The vulnerability exists in QuickTime’s handling of media streamed over the RTSP protocol. If you are a bad guy all you have to do to use this exploit to attack someone is to get them to open a specially crafted RTSP URL (a url starting with rtsp://). If the victim’s browser has JavaScript enabled you can make things even easier for yourself, you can get JavaScript to open the RTSP URL for you! What this all means is that you can now have your Mac compromised by simply visiting a web page. This is a lot worse than the Trojan that I discussed a few weeks ago where you had to actually download and install a program giving it admin access in the process in order to be compromised. I should mention that this exploit does NOT give the attacker admin access to your machine, it ‘just’ lets the attacker run any code they want as the user running QuickTime. This is not as bad as an exploit which would allow the attacker to execute any command as root/admin but it’s still very bad.
You can get more details from US-CERT. That page also gives you some guidance on protecting yourself. However, those instructions are very windows-centric.

Another Nice QuickLook Plugin
Filed Under Computers & Tech on November 26, 2007 | Leave a Comment
Following on from my post yesterday about the Enscript QuickLook plugin I came across another nice QuickLook plugin today. When it comes to viewing images, movies, text, office documents etc. QuickLook is great. When it comes to showing you a folder it is USELESS! It just shows a massive folder icon. What’s the point of that! Well, Folder.qlgenerator offers a nice alternative. It shows a list of folder contents with thumbnails as the QuikLook preview for a folder. This is a great little third-party tweak for OS X Leopard.

Bart’s TimeMachine Tips
Filed Under Computers & Tech, Security, System Administration on November 25, 2007 | Leave a Comment
Time Machine is the fantastic new backup feature built into OS X 10.5 Leopard. It’s pretty simple to set up and it will work if you leave all the defaults as they are. The defaults are fairly intelligent. For example, your Library/Caches is automatically excluded from the backup. However, if you wish to use space on your Time Machine disk efficiently you may wish to configure Time Machine to exclude a few more folders.

A QuickLook Plugin for Programmers
Filed Under Software Development, Computers & Tech on | 2 Comments
This week I installed my first QuickLook extension, QLEnscript by Dave Dribin. It uses the Enscript libraries to provide syntax highlighting for a number of common languages within QuickLook. Nothing fancy but handy for programmers none the less. You can find out more in this post on Dave’s blog.

Breaking News – Leopard Menubar Transparency Fix
Filed Under Computers & Tech on November 19, 2007 | 8 Comments
Yesterday I pointed out that OS X Leopard actually looks BETTER on old hardware because some of the fluff is turned off. This obviously implies that there is some hidden internal setting for controlling the fluff. Well, someone has found that setting! With a simple terminal command you can now get the nice solid Menubar on any Mac. Just fire up a terminal and enter the command (all on one line):
sudo defaults write /System/Library/LaunchDaemons/com.apple.WindowServer 'EnvironmentVariables' -dict 'CI_NO_BACKGROUND_IMAGE' 1
You can only do this from an administrator account and you’ll have to enter your password. The command won’t have an immediate effect. You have to reboot your Mac to see your new and improved Menubar. I’ve tested this on my G5 PowerMac and my MacBook Pro, it seems to work flawlessly.
You can get more details in this ars technica article.

The Irony Of Leopard – Old is Better than New
Filed Under Computers & Tech on November 18, 2007 | 5 Comments
I have Leopard running on a range of machines from a first generation MacMini with a G4 processor and 32MB of graphics RAM, to a 17″ MacBookPro with a CoreDuo and 256MB of graphics RAM. Leopard runs brilliantly on both machines, however, there are some subtle differences in the visual window-dressing Leopard chooses to use on these two machines. This results in Leopard being a little more visually pleasing on one machine than on the other. Naturally you’d assume that it’s the modern machine that gives the best experience, but you’d be wrong. Surprisingly and somewhat ironically it’s the old G4 on which Leopard looks the best. This is because some of the fluff is disabled on older machines like the G4 MacMini. The two biggest differences are in the presentation of the Menubar and TimeMachine.

What’s In Your Menubar?
Filed Under Computers & Tech on November 17, 2007 | Leave a Comment
I like to make a clean start from time to time. When you make a clean start you soon realise what applications you actually need and use and what’s just wasting space on your system. I decided to use the arrival of Leopard as an excuse for a long over-due clean start. A few weeks have now passed so it would seem like a good time to take stock and see what applications I’ve actually re-installed. It would take me for ever to write about all the apps I’ve installed so instead I’m just going to talk about a sub-set of the most visible of all apps, menubar apps. It should be noted that all the items in my menubar are either a part of OS X or free.
