Category: Technology

I work in technology sector. And I do round a clock, not only from 9 to 5. It is my bread and butter, it is my hobby, it is the fascination of my life. And with the current rate of change particular in information technology (IT), there is always something new to learn, to try, to talk about. I often post news, thoughts, and reviews. And when I do, this is the category I use.

Critique of Where Perl 6 is Heading

There is an article at FreshMeat.net that talks about Perl 6 and the way the development is going. The author is mostly against this way. The article is followed by a number of comments both in favour and against of the points stated. There is also another discussion at PerlMonks if you are interested.

I do have my doubts about Perl 6 too, but I havent’ yet looked into it seriously. Perl 5 is way more than enough for me and I don’t see myself changing to anything any time soon. I’ll let you know if I’ll change my mind of course.

Thought of the day

At 4:00am most of the Linux (and UNIX for that matter) machines start executing a bunch of scripts that clean up temporary files, update file databases, and all sorts of other maintainence work. For those, who know, I am talking about cron daemon. Obviously, such a heap of activity increases the power consumption of each individual computer and thus can be monitored by the electricity authority. And probably it is. The useful thing here is that this monitoring can be used for estimating the number of Linux/UNIX machines in the geographical area, such as a region, city, or, even, a country.

Editing image EXIF comments in KDE

It turns out that viewing EXIF data and editing image comments is a breeze using KDE’s file manager Konqueror. All you need to do is right-click on the image and select Properties from context menu. Meta Info tab will contain all EXIF data from the image. You will also notice that you can change the content of the Comment area. Type in your comment and press OK button. Presto! Your input was saved as EXIF data inside the image.

Preview thumbnails in KDE

One of the excellent programs that comes with KDE is Konqueror. Konqueror is a file manager and a web browser. One of the nicest features of Konqueror is autogeneration of preview thumbnails. This helps a lot when dealing with image repositories and photo albums.

When working with a lot of images, one can notice that Konqueror does not generate preview thumbnails for all of them. This is because it hits the limit on the file size set by default. That is easy to correct though. To fix this, start kcontrol, go to KDE Components where you need to select File Manager in which choose the tab marked as Previews & Meta-Data, where you will find a bar marked Maximum file size. For the images coming out of my Digital Rebel I set a 6.5 MBytes limit and it seems to work nicely.

Top 10 Ways to be Screwed by C

Sharing of experience is always welcome. In computer programming environment it is essential and vital. Today I came across one of such sharings – “Top 10 Ways to be Screwed by C“. It is C-oriented, but some problems can be easily seen in other languages too.

Oh, and there is actually more than 10 ways listed there.
