Google Reader Tracks Everything

Most people may not know, but Google Reader tracks every single entry you have ever read and there is no way to clear that list even if you remove all your subscriptions. Check out this link:

For me, this page shows some very old entries from the subscriptions I removed a very long time ago and there is now way to wipe it out! For this reason I wouldn't use Google Reader. (FYI, I use Cheetah News, which is a far better reader anyway, at least for me.)

Lifestreaming

As some people already know, I recently launched my own lifestream (or Stream for short). In effect, my weblog will be updated even less often. My new stream is powered by the gLifestream platform.

gLifestream is a free lifestream platform and social activity reader. It is licensed under the GNU General Public License, version 3.

gLifestream joins several external and/or internal streams into a single one. External streams may be represented by RSS/Atom channels or popular services such as Twitter or FriendFeed. The user decides which of them are publicly visible and which are not. Public streams are visible for anybody. The rest of streams are visible only for logged in users.

[image] GDB 7.0 released

GDB 7.0, the GNU Debugger, is now available for download. There are many interesting improvements and bugfixes, but I find two new features worth a special mention. Those are "reverse debugging" and "Python scripting" support.

The first one allows to run programs backwards, written in any language supported by GDB. Of course this isn't a trivial task, since rewinding a program requires a lot of extra work on tracing variables, registers and other stuff and not every target environment can support that. GDB provides several new commands for reverse execution. Most are just counterparts of the original commands, but prefixed with the "reverse" keyword, e.g. reverse-continue, reverse-step, reverse-next, etc.

The latter feature allows for Python scripting with GDB by providing the gdb module in the Python code. This heavily extends GDB possibilities, from a simple pretty-printers, through custom GDB commands, to any Python code you can possibly imagine using GDB API. Someone even recently scripted a "gdb over irc" :-).
