Swedish MacWorld claim shell commands are easter eggs

In this article in Swedish MacWorld, the journalist claim one can find “secret easter eggs” in the Terminal program. You find them by “copy and paste” special code into the window, and voila, you can get tetris (in emacs), and calendar events. Wow! Visste du att det finns närmare trettio spel gömda i Terminalen? Eller att det finns en dold kalender med viktiga händelser i historien? Det är bara två exempel på så kallade påskägg som uttråkade programmerare lagt in i Mac OS X. […]

Broken Mail.App

Mail.App is really broken when it breaks. The unfortunate thing is that the application itself does not notice when an index is broken. Two examples on what happens when things break:

  • The information in the index of sender, date etc is not correct. If one look in the list of email, and compare with information in the mail, you will see they differ.
  • See the picture, I think that should be enough…
  • […]

    Delete Duplicates from MacOSX Calendar

    Some people on a mailinglist for MacOSX asked about mechanisms for removing duplicates from the Calendar application in MacOSX. I have been using this AppleScript for a while, and it works for me. I have not written it from scratch myself, and unfortunately I do not remember where I found it the first time. My apologies for not referencing the original creator. I sent this script to the mailing list, but some people say they where not able to receive it correctly. Because of this, here is a zipped version. […]

    MacOSX 10.4.9 released

    Apple at last released version 10.4.9. Release notes can be found here. Interesting things for me include:

  • Event notes are now synced between iCal and Nokia N70 phones.
  • Adds iSync support for more devices. Otherwise, not much exciting no explicit mentioning of fixes of Mail.App. Is it time to change email client? I guess we all are waiting for Leopard. […]

  • At last, support for 3G express cards in MacOSX

    Last update of MacOSX have support for 3G express cards. […]

    Size of a Huawei USB modem for 3G

    People ask what the size of the USB modem is from Huawie that I just wrote about. You can see it compared with the 85W power adapter for the 15″ MacBookPro. […]

    3G USB modem with MacOSX

    Yesterday I bought a USB modem for 3G access. I hopefully will get easier access to Internet when I need it than when using a USB cable to an LG phone. Fewer things, no need to make sure “the phone” is charged all the time, and more stable drivers. Hi3G in Sweden (that I have a subscription with for 3G data access) have the Huawei E220 3G USB modem for sale, and drivers for MacOSX exists. It is though important you really read the details in the instructions, including that you run the two install packages in the correct order. They are named with prefixes “1” and “2” on the file names, so it is not so hard. The connection is flawless, and it “just works”. […]

    What about MacJournal

    Now I am checking yet another software, MacJournal. I have tons of things to remember, some of them to be blogged. Maybe this tool can help me? This is a new line, with Swedish räksmörgås in it. […]


    So, I am going to try to use this ecto software again for the blogging. If I don#039t have to use a web browser all the time for adding data to this blog, I might do it more often. The overall question is of course how to add images… I have had problems with ecto earlier. See this post from me earlier, and this post about what might trigger bugs. […]

    Crontab on MacOSX

    People ask me “what about this crontab -e command”. And of course not everyone feel comfortable with the terminal window to edit system files. You can for editing the crontab file use the program cronnix instead of the terminal window. […]
