I guess I’m not much different to you. We have our blogs which we read quite regularly or not so.
I found that a few are quite intersting (well I’d appriciate a bit less four letter word) but here we go:

Comment: I’m a long time linux user (at least 12 or so years) and I found it mostly useful to me. Howerver a few things really upset me. One among the first is the attitude towards “non-free” software. Howerver I do disagree with the attitude that “all-is-bad”. No it’s not, if it happens that your system is proper configured, you simply can forget about it. That’s was worse with Windows in the past but the only OS from Windows I avoid like the plague is Vista. I’m sorry this really sucks (especially for programmers) I had to work with it and had to develop software for it. It was on of th emost ugly experiences… WS2000 just works find, as does WS 2003 (be it 32 or 64 bit), XP is as good.

I few things are bad done in Windows (AFAIKT) it annoys me that all the programs and user data are put into one partion by default. One can modify the setup, but it still is work.
Over all the time using Windows I found one think a bad design decision. The Registry was not a good idea, by all means the Unix approach using plain text files in /etc is simply better.
It’ never is a problem on Linux to move directories it’s a very bad idea doing that on Windows boxes. If they had decide upon the Registry, why havn’t they used a relational database with proper accesses? Expecially bad is the needed framework for registering COM stuff….
And despite other means I foiund the documenation many times not that good, but most of the Linux stuff is not better.

Annother thing I dislike is how they mistreat there C base. The whole systems are build upon Windows C and they do nothing to adhere to the “actual” Standard. Instead you have to use some crude mixture between C/C++ ….

However it seems Microsoft has gone to great pains for backward-compatability. For that
http://blogs.msdn.com/oldnewthing/ is a must read.

Most often I found the following good reading:

Because I’m interested in programming (especially programming languages) I read a lot of the
Planets for certain languages. Search for Planet {Scheme, Lisp, Smalltalk, …} and read a quite of them, there are good arguments (and bad ones too 😉

Sometimes you think the entries are parody but it seems that “it can be worse” is well established in programming circles:

That’s for now I may add a few other interesting blogs over time. If you found some very useful feel free to share them….
