syslogd gone wild

January 8, 2008

Since Leopard my mac sometimes begins to freeze and I recognized that my syslogd is running at 100-150% with 1Gb of virtual memory. I wondered a little bit about it and began digging in Google.

My research ended in a guess. (If its wrong – please drop me a note)

The reason is, that buggy programs are filling up the syslogd with debug messages – mostly Apple Event Debug messages in my case. When the file /var/log/asl.db is over 20-25 mb big, the syslogd goes wild

so execute in your prefered shell

     sudo rm /var/log/asl.db && sudo killall syslogd

and it will stop for a while.

 

I am looking for a permanent solution. If you know one – please drop me note.

have fun

change the 3D Dock in a 2D Dock (Mac OSX Leopard)

November 18, 2007

One week ago I installed Leopard. Well I am quite happy. There are some disappointing bugs, but I hope they will be fixed soon. (like my beloved python does not compile and mplayer from macports works only with disabled SSE and MMX).

Another thing was the 3D Dock. I find it a little bit ugly. So if you want to change it to 2D, here’s the trick.

open a terminal an execute

defaults write com.apple.dock no-glass -boolean YES; killall Dock

You can undo this with

defaults write com.apple.dock no-glass -boolean NO; killall Dock

 

have fun

jabber – why it rocks

August 20, 2007

Jabber – why it rocks

Jabber is an instant messenger based on the XMPP, near real time XML streaming/routing protocol.

There are tons of specifications out there – but what does it actually for you. Well think of a protocol, which does not need a port for every extension and with that every function you use.

You can have a client capable of sending text messages over XMPP. One day the developer of the the chat client decide to extend the client with a white board and you and your friends can now draw images together. And maybe other developers decide to implement some telephone features – now you can talk to your friends.

The really nice thing is – if you have a fully functional client for speech, chat, drawing and your friends not – the clients are not useless. the client “knows” which features it implements – and gives you the best he can offer.

But its not only for chat and drawing – because there is enough stuff out there. The interesting stuff begins when you use it as a transport layer for web services. Imagine you can see the status of your coffee machine in your chat client. or you get every time a message when someone of your project group add some code to the subversion repository. Fiction ? no its working – and I love it.

A protocol which you can extend dynamically. Of course you can use it with SSL and Kerberos. All the beauty of network transportation on top of all layers.

Of course I am simplifying it, but its really easy and very extend able. So why is jabber so cool, if XMPP is the cool protocol. Because jabber does not care what it transports – its an XMPP router. You can use it for transporting all your XMPP streams through your networks and far beyond.

DxO Filmpack

July 29, 2007

Ever thought: well these digital photographs look nice, but I want my Kodak Tri-X look, and no matter how I squeeze the color-mixer, contrast and exposure it does never arrive?

DxO Filmpack does exactly that: it takes your digital photographs and simulates the look of a range of films and processing techniques, you can choose positive and negative color, black and white and cross processed film looks.

I tried DxO Filmpack, and it is very very impressive! Of course your first thought is, why the heck would I destroy my photographs with simulated grain? What can they do, what I can’t with the curve-tool? But when you see the results you will think: I don’t really care about destroying perfect files as long as this is what comes out – and no I could not do the same with the curve-tool – and actually the result is what matters.

Especially black and white films look great. A side effect of the grain is that over-exposed regions in the image don’t look blown-out any more. The color film options were nice, too, but there is something strange about a heavily boosted saturation that sometimes seems to be beyond the colorspace. … I’ll have to look into that. Anyway, I only really cared about Tri-X and Delta400. Try it with portraits!

easy eclipse go

June 28, 2007

Ever fumbled with that eclipse plugin on your mac? Ever thought: Were else should I provide the path to this and that?

EasyEclipse 1.2.2 might be for you. Its the free open source software development environment Eclipse plus a few plugins in an easy to install version for your mac.

smooth wake up service

April 21, 2007

I am using this tool every day and I nearly forgot to write about it.

The Alarm Clock for my macbook.

What should I say – its an alarm clock. And it smoothly ends my dreams with my itunes music collection.

I especially like the easy wake function.

one little hint: Don’t have your remote control near your bed, when you have an urgent appointment.

good night – sleep tight

TiddlyWiki – a happy geeky notebook wiki

April 10, 2007

When I first realized what the authors of TiddlyWiki had put together, I sat down and thought – wow … several times, for a few minutes. (This was after I had spent the night setting up a mediawiki, with lots of sql sweetness etc.)

TiddlyWiki is the most compact, self-contained, portable, superpowerfull, and neat to look at personal wiki, I could imagine at this moment. (remember … after spending the night …). Imagine it as a crossing between wiki, post-it collection, and todo list.

And: its all contained in a single html file, you simple download and open in your browser. That’s it, changes are saved in an xml file that is located in the same directory as TiddlyWiki. If you want to do a backup, or move it somewhere: just zip these two files, and copy or mail them. Minimum requirements: a web browser with java script enabled.

Very cool!

instiki: your very own wiki

April 2, 2007

If you are looking for an easy way to organize yourself Instiki might be for you. It is a wiki+server in a box, based on ruby, and runs locally on your PC/MAC/Lunix.

On my MAC I use Version 0.92 to organize all the various bits of knowledge, I would like to have quick access to, later on. Ver 0.92 seems to be the last version that runs easily i.e. stand alone on a MAC. You can get Ver 0.11p1 but you’ll have to go through quite an installation to get it running. However, the people over at instiki are feverishly working on getting Version 0.11p1 to run out of the box on a MAC, too.

Note to Ver 0.92: There seems to be a bug with exporting your wik. I will keep you posted, when I find a solution.

[Update instiki Export bug]: Ok, here is what I did to fix the export bug: in the file wiki.rb (included in the download) I have deleted the string ../../ from line 4. Now my exports work. One last catch is that after exporting all links to pages with names, that should have a + in it (for example [[this and that]] becomes this+and+that in instiki language don’t link, because they are exported to this and that.html. Anyway, they do exist. I will just avoid such links from now on.

[Update 2: it crashed – big time] Ok, instiki crashed on me. Maybe I should not have played around with newer versions (discovering, that if developer tools are installed on your mac, higher versions seemingly do work), maybe I should not have done a lot of things … it crashed! (%&$(/%$(/& it wont start up again! it wont start up again! thank god, i did one thing: fix this export bug, so at least my terribly valuable knowledge was preserved in the textile formated files.

What did I do after I started breathing again? Right, I got a full blown mediawiki running on my mac, just for me, alone, yes. MediaWiki is what is behind Wikipedia by the way, so a few million beta testers couldn’t be wrong. How i did that and what happened shortly after that I will tell you in one of the next posts ….

… stay tuned.

Journaler – a bloggers friend

March 29, 2007

This time I want to write about Journaler, a nice tool for blogging. It’s very easy to handle and has many nice features for writing. This is my first blog with Journaler and in the future I will give you now and then an update about my experiences with it.

The configuration for blogging is quite simple. Under Journaler -> Preferences -> Blogging  add a MetaWeblog API account.
The Blog’s Location is http://<your blog>.wordpress.com and the XML-RPC is http://<your blog>.wordpress.com/xmlrpc.php and of course you should know your login name and your password.

For now I can say. It exists, is easy to use and its full of features I want to try out. I also hope, that it will increase my blogging rate to bring you more cool information, about mac and free software.

Xee – easy image browsing for macs

March 22, 2007

Xee is a super slim image browser very much like preview, but: once you have opened an image, you can easily browse through the entire directory, just by your scroll-wheel. Remember irfanview back when you used windows? It’s exactly like it (minus some functionality but the easy browsing makes up for that)
