Great Read: The Graphing Calculator Story

Posted on 2006-04-29 By rolfje No Comments on Great Read: The Graphing Calculator Story

On one of my Google quests, I stumbled upon a great story about a few guys who got fired by Apple, but continued to sneak in and out of the building, finishing the software they had been working on. It is a great read, and I think it would make a nice adventure movie. It will probably will not be a box office hit, because the rest of the world does not know what programmers feel when being “in the zone”. It will probably end up in DVD shelves next to Office Space, one of my favourites.

I really enjoyed reading The Graphing Calculator Story, I hope you do too! Be sure to check out the screenshots 🙂

Apple OS X crash when importing in iMovie

Posted on 2006-04-29 By rolfje No Comments on Apple OS X crash when importing in iMovie

Just now, I had a terrible experience with my new Mac Mini. It crashed on me, two times in a row. It did this while importing a movie from a Sony Handycam with iMovie. During the import, suddenly the screen goes blank, and the machine does a “hard boot”. I restarted iMovie, dragged the imported files from the trashcan and continued as normal. But now I’ve noticed that my Spotlight is no longer returning search results. Looking for “Terminal” resulted in amsolutely no results at all.

I checked the /var/log/system.log for errors, but I can only find the things logged during boot. I expected to find some kind of error just prior to the unscheduled boot, but there is none. The problem is so “hard” that the system doesn’t even get (or takes) the time to write information about it.

I tried to repair the Spotlight database with the tips found here, and found the solution. Open the Terminal (from Application/utilities) and do the following (requires root password, be carefull!):

rolf:/var/log rolf$ sudo mdutil -E /
Password:
/:
        Volume index removed.  Index will be rebuilt automatically.
rolf:/var/log rolf$ sudo mdutil -i off /Volumes/MAXTOR\ FS/
/Volumes/MAXTOR FS/:
        Indexing disabled for volume.
rolf:/var/log rolf$ sudo mdutil -E /Volumes/MAXTOR\ FS/
/Volumes/MAXTOR FS/:
        Volume index removed.

Yes, you noticed correctly, I turned off indexing on my Maxtor 250 USB disk and cleaned it’s database as well. Spotlight indexes USB disks, and I thought it best to focus on indexing the system disk first.

After doing this I waited for Spotlight to finish indexing. You can tell when it’s finished by clicking on the magnifying glas. It takes about 2-3 minutes to finish on my machine. After it finished I still had no results. To give the system a chance to clean up and restart I shut it down, and powered it back up. Problem solved! Spotlight works fine again (phew).

Oh and another tip: don’t minimize iMovie when importing a movie from your camera, it will stop importing, but leaves the tape running, letting you think it is still working fine.

It seems that although OS X is more stable than Windows, and can cope better with unexpected reboots (never lost a file during this whole adventure), it is not entirely bullet proof. If I find a way to avoid reboots in iMovie I’ll let you know. Smaller projects and more saving is the way to go for now.

Connecting with different users to 1 server (2)

Posted on 2006-04-28 By rolfje No Comments on Connecting with different users to 1 server (2)

This is a simple followup after my last post. Pim did also look into this, and made a script which doesn’t pop up finders by simply calling “mount”. There is only one minor glitch: the script pops up an error when the mount already exists. With my brilliant programming expertise, I quickly solved that:

try
	mount volume "cifs://KAGE/iTunes" as user name "iTunes" 
                                          with password "yourpasswordhere"
	mount volume "cifs://KAGE/incomming" as user name "Guest"
	mount volume "cifs://KAGE/foto" as user name "Guest"
on error errText number errNum
	(* Not the nice way, simply ignore errors. If the mount did
	   not work, the user needs to see what is going on. How?
	   Use Finder to mount, and it will give you the error *)
end try

This script will try to mount the drives, ignoring errors. Replace the servernames, usernames and passwords with your own. What you can do is run the script at logon, or every minute in a cron job. I checked /var/log/system.log, but the script does not generate errors there.

At the rate we’re going, maybe we’ll even solve the “re-mount drives on return from sleep” problem. Let’s see if we can find a wakeup event on which we can run the script.

Connecting with different users to 1 server

Posted on 2006-04-27 By rolfje No Comments on Connecting with different users to 1 server

With my Mac mini in a Windows LAN, I have the following problem:

  1. I can add my (cifs windows) network shares to my login script (Preferences -> Accounts -> Login), but when the mac wakes up from sleep, they are gone.
  2. When I want to connect to 2 shares on the same server, but one with a different account than the other, it doesn’t work. On login, the system chooses one of the accounts and uses it to connect to both network shares.

I think both problems are terrible, and particularly the way you connect to a network share in Finder using a password is confusing to say the least. Searching the web reveals hundreds of posts of people having the same problems. One wonders why apple didn’t solve this already.

I made a simple workaround for this problem by copy/pasting some script from several websites into the script editor (sorry guys, I’m lazy). I then saved it both as application and as source. I use the script to mount the drives at logon, and re-mount them when the Mac wakes from sleep mode. Until I come up with a better idea, or somebody can point to a nicer “Apple way” solution, or Apple fixes this dreadful problem in OS X, here is my script:

tell application "Finder"
	open location "cifs://WORKGROUP;iTunes@KAGE/iTunes"
	open location "cifs://WORKGROUP;Guest@KAGE/incomming"
end tell

When running a script like this for the first time, the system asks you the passwords. Type them in and save them in your keyring. The next time they won’t be asked, and you have no readable passwords in your script. Nice. The downside of this script is that it opens a ton of finder windows. I have nosed around in Automator but can not find a way to close them automatically. I also tried to record a script, but that gave me an even more “unusable” script.

I hope this helps you too. If you think this can be done in a nicer way (without too much scripting) please let me know.

Update: Seems I was to quick about the keyring app. I did need to add passwords to the script (add “:password” after the userid without the quotes). Stupid machine does not understand what I want.

Flip4Mac 2.0.2 does not install on Intel Macs

Posted on 2006-04-24 By rolfje No Comments on Flip4Mac 2.0.2 does not install on Intel Macs

Bummer, I was hoping to be able to open those wmv files I get mailed in the Quicktime window. Although OS X claims to be supporting Flip4Mac since 10.4.5 (I have 10.4.6), the Flip4Mac installer exits with a message about not being able to install on Intel based hardware.I guess I’ll have to live with -gasp- Windows Media Player 9 for OS X for now. I tried to install it, but it requires mee to enable the Microsoft Office testdrive kit, which I am definetely NOT planning on doing, wmv files are not worth those troubles. I am hoping on a universal binary Flip4Mac soon…

Funny thing is, that the Windows Media player for OS X is actually only 7 MB in size. I seem to recall that Media Player 10 for Windows XP took quote some time downloading, and ate nearly all of the free space on my harddisk, which I was really pissed about. But then again, since they require me to enable the Microsoft Office testdrive, they have probably allready sneaked part of the player into the OS X distribution, the bastards.

Comment from Antonio on how to solve this: You can get Flip4Mac to work through Rosetta, but Telestream is a couple weeks away from releasing a public Universal beta version. Check this blog for some details and other info bits: http://flip4mac.blogspot.com/

My response: Great, just used the tip on blogspot, and it worked! I can now view wmv files nicely. Thanks for the tip!

Getting iChat to work with Googletalk

Posted on 2006-04-23 By rolfje No Comments on Getting iChat to work with Googletalk

This is probably the 1001st post about this subject, but I can’t help thinking that some people actually give up on this. It is a simple protocol, simple program and should be simple to get working. I spent a few hours (!) before I finaly found the solution. I searched the internet but this answer never seems to be given on forums. I’ll try to be complete, so here it goes:

Configure iChat as described by Google. If you still can not connect, there is a good chance you have started the firewall on your mac, and it is blocking iChat. Open the system preferences, and in the “Internet and network” section select “Share”. You will notice a firewall tab in the middle. Select it, and make sure there is a thickmark next to “iChat Bonjour”, like in this screenshot:

iChat settings

(Sorry for the Dutch layout, I’m sure you’ll find it with this pointer.)
This action solved my iChat connection problem. I also installed Adium, which also had connection problems. The firewall setting solved the Adium problems aswell.

I’m not sure which chat client to choose. iChat is more integrated into OSX, and imported my google contacts without a problem. Adium did not import any contacts. I’m sticking to iChat for now, hoping that the integration with the rest of the system will give me some pleasant surprises.

Oh and yes, you’ve noticed correctly, I’ve bought a Mac. The desktop PC at home crashed one time too many.

Want those CD boxes back?

Posted on 2006-04-23 By rolfje No Comments on Want those CD boxes back?

When I used iTunes on XP, I was jealous of the terrific plugins for iTunes running on OS X. Now that I have a Mac Mini, I was looking for a plugin to update the album art automatically. Pim showed me an even better alternative: Clutter! Not only can it search and update album art automatically for you, it also gives you the option to put your albums on your desktop. This is the best virtual alternative to having CD’s lying on your desk. A must have for iTunes users I think. Very nice.

Sidebar: My file server still runs Windows, and it has been working flawlessly for the past 5 years, being constantly “on” and storing family pictures and music. My laptop is an XP machine and works quite nicely too. So maybe it’s because I don’t need to, but for now I don’t want to install XP on my Mac. It feels like a step back, it adds a sour taste to your strawberry icecream :-). XP is nice, but not as a desktop. Too much bloatware.

The real bike simulator

From the makers of Gran Turismo:

Tourist Trophy banner

Is this great or what? It clearly is built on the Gran Turismo 4 rendering engine, and supports everything we’ve come to expect from Digital Polyphony. Arcade and Trophy mode, Photoshoot mode, a bucketload of (real life) tracks, and a truck load of different bikes to choose from!

Looks like my next addition to my PS2 game collection…

Pully party

Posted on 2006-04-01 By rolfje No Comments on Pully party

Party today! The rotor puller I ordered last month finally arrived after being in transit for over a MONTH, “thank you” United States Parcel Services! They probably sent somebody to swim accros the ocean with my parcel on his back. Judging by the shipping costs, the swimmer had enough food luxury during his trip. I really hope that Pit Posse selects a different shipping company for international orders soon. I took the torch and heated the rotor until water drops put on it boiled, to soften the retainer (lock tight) between the axle and the rotor. Then I re-tightened the rotor puller, smacked it with a hammer, re-tightened it, and so forth. The fifth hit did it, the rotor popped out. As you can see in the first picture, I had a fire extinguisher close by, because oil and fire do not play well together. I also used gloves so I could grab hot metal parts if needed, and I used aluminum plates to protect the magnet from direct heat of the torch.

Kawasaki KLR wrenching fanatics will notice the missing balancer chain tensioner (or “doohickey”, as they are sometimes called). Don’t worry, it’s still in one piece, I took it off to straighten it. It was bent and worn by the holding bolt, and I don’t want the bolt to sit or crawl to it’s former spot.

I also checked the valve fittings by putting petroleum in the head. They do not seem to be leaking, and show now signs of abnormal wear. Next week I will be checking the old oil for metal splinters, and putting it all together.

Airbus 330 Entertainent system

Posted on 2006-03-31 By rolfje No Comments on Airbus 330 Entertainent system
I recently went to Vegas, which is a very long trip (about 20 hours including stopover). I don’t like flying that much, my ears hurt and it is very boring to be crammed in a chair for 10 hours, with a headrest that makes your chin touch your chest no matter how you adjust it. However, on this flight (and the one back) there was a nice personal entertainment system installed in each chair.Below are some images of the personal entertainment system which is installed on the Airbus 330’s of Northwest Airlines. These are a real treat on long distance flights. There is a fair selection of on-demand movies, music, some simple games and flight information. It lets you choose a movie, and you can pause and skip as much as you like. You can use your own 3.5mm jacked headphones, no more of that adapter-buying-if-you-are-lucky-you’ll-get-stereo crap you see in the older planes. The menu even contained an item called “email”, but it was not functioning at the time I tried it. Besides you had to swipe your credit card for it, which I didn’t find worth trying even if it would work.

Bejeweled Controller Flight information Movies
Nice little game, Bejeweled The controller (has to be turned 90 degrees sometimes, confusing!) Guess where we are? Travelling at 950km/h there 🙂 Watched Chicken Little. It does not live up to it’s commercial by a long shot.

Funny thing is, that my wife’s entertainent system actually crashed during flight. It got stuck for about 5 minutes, after which it automatically rebooted, and guess what? I saw a Tux! It is actually a Linux system. A bit of googling revealed that a few people even have seen the system crash on all monitors at the same time. Good thing they aren’t using this system for the flight controls yet. 😉

But it does make sense. It doesn’t cost anything, and being open source, Panasonic (the manufacturer of the system) has full controll on getting all the glitches out. Now they actually do need to do that still, but I bet they got a nice (remote?) update procedure for that. After all, they also need to upload new movies every now and then. Maybe they use the same connection as they use for email? 100% remote update would be nice. No “downtime” for the planes!.

I for one liked the system very much. It actually has games which let you compete with other passengers, but that didn’t seem to be popular on my flights to Las Vegas. I didn’t even had to get my PSP out of my bag 🙂

Now if they only could make those stupid headrests removable so I can put my head back when I want to sleep (like most normal people), flying wouldn’t be all that bad.
