buying a iMac?

I like the concept of the new iMac. What I'm a not sure about is the Mac OS X. As I had to switch between system not only over time but also between work and home, I started using programs that run on all platforms.

At this time all platforms for me is Linux, Windows and sometimes OS/2 and IBM 370/MVS. Adding an other OS to this, needs some good reason and all the tools I use 99% of the time. As OS X is based on BSD it should not be a big problem.

First quick draft of the programs I use:

  • zsh

  • emacs - moving more and more to eclipse

  • perl

  • Java

  • mutt

  • ImageMagick

  • ssh

  • mpd/mpc


To add programs as I use them, I will look up the home page and add the tag useprg and osx if it runs on OS X on del.icio.us.

And now some hardware I should be able to use:

  • external USB drive with ext2

  • Palm Tungsten

  • SD card or SD card reader (USB)

  • mobile phone

  • ISDN phone

  • scanner

  • ham radio



Not everything will be usable from OS X directly. Most of this should run in VMware or parallels. Problematic will be the RS232 and IEEE-488 equipment.

eclipse installation

For the update of eclipse 3.2 to 3.3, I downloaded Eclipse IDE for Java Developers from the Europa Packages. Unpacked it into a different folder as 3.2 is located. This enables me to use 3.2 and 3.3 till all the packages I use work with 3.3.

Started the new eclipse and installed all the plugins I used with 3.2.
Help / Software Updates / Find and Install .... Select Search for new features to install. Include all sites into the search. First I selected only the ones I had installed with 3.2.

  • C and C++ Development

  • Database Development

  • Web Standard Tools


Now I installed the plugins I used with 3.2 but which are not part of Europa.

Not installed, because not needed at this time.

Download of eclipse exists for linux, OS X and Windows. None of the installed plugins are OS dependent.

what rss feeds should I read?

Quite often you find a blog that looks interesting and you subscribe to it. Not long and you are unable to read all new post a day. Worse if you stayed a weekend of the Internet.

The google reader Trends page will show you how many posts and the percentage you read of a subscription. Also how many posts you starred and shared. There is also a list with items a day (over the last 30 days) and in reverse order the date of the last post.

For me I defined some rules to use the statistics to find feeds I

  • need to read

  • my read if I have some time left

  • could unsubscribe


Process the whole feed in one pass. This prevents me from looking at the same post twice. An entry I've read and found interesting will be marked as read. An article of more general interest to my friends, will be shared. If it is only of interest to one or two, the post will be mailed directly to them.
If I'm in a hurry and not able to read an interesting post complete or need more time to follow all links referenced the post will be stared.
At the end of the feed mark all as read. This will remove the posts from the list and add they as not read to the statistic.

The art of reading feeds like this to keep the list with stared posts near zero.

Regularly you should delete feeds where the number of read posts is under 10%. Or could this number be higher? Lots of posts I'm interested in get posted to several feeds I read.

At this time google reader will display only up to 40 feeds in the statistic and it is not possible to change the order. If you subscribed to more than 40 feeds you can't see the ones you haven't read even one post from :-(
Also missing is the date you subscribed to the feed. As the statistic is for the last 30 days, the numbers are bogus if you subscribed less than 30 days ago.

share files on the net

The ExtremeTech article 5 New Ways to Share Files compares web services that provide storage space. The idea is instead of sending somebody a large file as mail attachment you only send the link.
I'm a big fan of this. At work I get lots of mails with huge presentations as CC. Quite often the subject line tells me that I'm not interested in this mail.

So far I used my own web space to share the attachments or rsynced the files to a friends server. The alternative of this web services is more to tell friends about without a web space and/or computer knowledge.

A quick look at the comparison table gave me the winner: FileCrunch.

  • no login for the recipient

  • no extra client to install

  • storage time 30 days


The recipient will see some advertising before the download starts.
An alternative is YouSendIt. But the storage time is only 7 days. This could be to short in case of an vacation or a delayed download at busy times.

download google video onto my palm

I started to watch Inbox Zero on my PC. Stopped it as I didn't like to watch this 58 minutes inside. But how do I get this google video onto my palm to watch it in the park?
I found a description about linux tools and a d.i.y description.

As I was in a hurry, I followed the diy instructions.

  • went to the google video page

  • pressed the download Windows/Mac button

  • this revealed the link to the gvp file I downloaded

  • used wget to download the url inside


The url was to long to be used as the filename on my windows notebook. Therefore I used -O to name the output file myself.

The size of the downloaded video is 480x360.

In the suggestion area of this google video side lists a lot of educational videos. This looks like to be worth investigating.
