Hi all, I know this approach is extremely non standard, and that Haifux is a club with no registration required attendance. I've been asked by some of the Haifux admins to give the lecture I'm about to give this Thursday at Herzelinux also at Haifux (August 10th is shaping out to be the date). I will gladly do so, but.. Giving a Haifux lecture requires some effort on my part. Aside from everything else, this requires getting out of work at about 4 pm and drive to Haifa, as well as drive back after a day in which I both worked and drove and gave a lecture. All this I will gladly do, and enjoy it, except for one problem. More often then not, there are only about five people present to actually hear the lecture. It seems to be a lot of effort to achieve not much effect. I, on my part, am more than willing to leave work early, drive both direction and give the lecture, but you have to do one thing in return. Show up. So I am asking this publicly. Assuming I do give a lecture on profile guided optimization on August 10th, how many people intend to get out of whatever important other stuff they usually do and show up? Quite frankly, if it's about talking to an almost empty room, I don't think I'll bother. Also, please note that if 20 people say yes, and then I show up and there are only five people present, I will have to seriously consider whether I want to ever make the effort again, so please only say yes if you truly think you will actually be there.

Myself, I use vim and gdb, and rarely ever write software with more than one thread (per process, that is ;) ). This is intended for other users, which are not necessarily highly familiar with Linux programming, and the ideal solution for my problem would be an all-in-one GUI debugger (such as DDD). I am, however, open to any neat tricks you might have in mind, which are not in silver-platter-GUI form. Hai: Thanks, I'll take a look at Insight. (Doesn't seem as nice as ddd though, not even a builtin gdb console... what features should I look at?) Yes, its GUI looks eagy. It does have a gdb console (View-Console - its not a shell console but gdb console). Insight did a best job for me debugging project that heavily used C++ templating, where ddd got lost tracking source code. Yotam: We're a VIM shop ;) (and still, would this be beneficial? I'm pretty sure that it's a rather thin frontend) Gabi: Debugging is rarely intended to verify code correctness, nay? :) But gdb is indeed capable of those features, they just seemed pretty basic to me. Guy: The solution to the single-stepping problem would essentially be suspend all threads but this one, which indeed gdb can't seem to do. I'm not sure why. At any rate, thanks for the input, guys.

Disk scan is done every boot, however on journalized file systems it usually just checks/replays/purges journal. In other words, is there any time during the life of a disk running a journalized filesystem when the filesystem is practically corrupted?
