hey folks,
couple of days ago i was wondering why my new access point was so lame (transmitting some big files through wifi). so i’ve decided to tweak it a little bit up and use the 5ghz band. it was really a improvement for large file transmissions, because my environment here is full of disturbers. but, i was really pissed-off as i noticed that my iphone was unable to connect to my network anymore. yeah, iphones are 802.11n ready, but only with 2.4ghz 
here i have some links for you …
iphone 4 has 802.11n, but not the “awesome” 802.11n
which is better: 802.11n 2.4 ghz or 5 ghz?
802.11n 2.4 ghz vs. 5 ghz
hey folks,
do want to retrieve some files from a directory with the http protocol in a fast way? in the gnu wget manual you’ll find some possible solutions. but this particular command was my favourite:
wget -r -l1 --no-parent -A.pdf http://www.server.com/dir/
here we are, all pdfs downloaded from the directory!
sorry guys for spamming today,
but “hacker news” got a really interesting link to slideshare [1]. what will you find there? here is the summary of 445 pages 
• compiler and linker
• declaration vs definition
• activation frame
• memory segments
• memory alignment
• sequence points
• evaluation order
• undefined vs unspecified
• optimization
• something about C++
• proper initialization of objects
• object lifetimes
• vtables
• rule of 3
• … and something about attitude and professionalism
don’t be afraid … there are not 445*80 lines of dry lecture on those slides. you will find jokes and humor – but the wisdom won’t come too short, believe me!
hey folks,
i’ve forgotten to post this cool link … here are some facts about it [1]:
How is JPEGmini different from JPEG?
JPEGmini files are optimized JPEG files, whose parameters have been tuned to significantly reduce the file size without affecting perceptual quality.
How does JPEGmini compare with JPEG2000, JPEG-XR, WebP, or other image formats?
JPEGmini uses the standard baseline JPEG format, which is by far the established market leader in the image compression space. Newer formats such as JPEG2000, JPEG-XR and WebP have not gained any significant market share yet. Although these formats presumably offer better compression than JPEG, JPEGmini’s unique recompression technology can produce JPEG files that are smaller in size than corresponding JPEG2000, JPEG-XR or WebP files.
What is the typical file size reduction I can expect from JPEGmini?
This depends on the resolution and quality of the original photo. For high-quality, high resolution photos produced by digital cameras, you can expect a reduction of 50%-80% in file size.
so, before you start attaching monstrous jpeg photos to your email – shrink them with jpegmini.com!
hey guys,
school is starting and i’m again in the class room. so, we all know how good the internet works if you really need it. therefore i need my prezis offline, but i’m not in the mood to startup every time my virtual machine when presenting a offline prezi (only mac and win is supported). after searching for some seconds in the world wide web i found this very cool information!
here is a short description of the necessary steps:
- copy the data folder to a wished destination (e.g. ./prezis/topic)
- copy prezi.app/Contents/Resources/movie.swf to this destination
- add parent directory as a trust worthy location through the flash settings-manager (here)
- open the movie.swf file in your flashplayer-capable browser
et voila!
thank you very much, pavol rusnak!
german umlauts and code documentation doesn’t work very well together … so we need the well known replacement table:

hey folks,
i know, it is kind of a religious discussion – but, i am on the light side of the force
here you can find a very good introduction: “learn vim progressively” … it’s really easy!
may the force be with us!
don’t forget your towel!
