Thursday, January 31. 2008King of the hill
John, don't get too excited.
I hate to disappoint you, but I got #1 for “mysql takeover” on the very day I wrote about it. I also seem to be #1 for “CEST software”, simply because these are appearing next to each other whenever I post something about software, during CEST months. And I was on top for “converting from metres per seconds to metres per days”, too, but my silly post about it from two days ago already took over. For all I know, there are a few more like these, though none are obvious from search referrals yet. I guess being on a few planets might be very good to your Google karma. (or should I say, pagerank?) Tuesday, January 29. 2008Why globals suck
To the people looking for a way of converting from metres per seconds to metres per days: multiply your value by 86400 (60 for seconds in a minute, times 60 for minutes in an hour, times 24 for hours in a day).
One of the disadvantages of using dynamic web pages, is that you might end up serving pages (depending on how the application works) that basically say: "I can't find what you're looking for". Over the last hour I've kept half an eye onto the webserver logs for this weblog, and noticed that the Google crawler tried to index pages which simply aren't there, like for example an archive view for the year 2083. But the underlying PHP script happily returns a HTTP 200 status, with the message that filters don't match anything. Hardly useful. I also ran trough a large part of the site, checking if any page could refer to such 2083 archive, but haven't found any links to it. Which leaves me wonder why Google came to it. On faulty pages; for the last couple of days I've also been updating the script code to some extent, and through the log following of the server logs I noticed that some links were broken (and did not return 200 but 404 instead, or, in case of the comment code, made it impossible to post anything at all). Largely due to modification of a global in some code path, which variable was used later to build up these broken links. I think I've covered all faulty links; but if I oversaw any please let me know, I can be reached by email at mechanix on rack66.net. Tuesday, January 29. 2008
Task scheduler annoyances Posted by Filip Van Raemdonck

Comments (0) Trackback (1) Task scheduler annoyances
Apparently, the task scheduler in all Windows NT-derived versions up to (and including) Windows Server 2003 cannot run jobs under the "NT Authority\Network Service" security principal; "NT Authority\System" is the only so-called well-know security principal that can be used with it. Support for running tasks as "Network Service" or "Local Service" was only added in Task Scheduler 2.0, which is the version that ships with Vista and will be also included in Windows Server 2008.
Side note: I wonder why the link above, being a command reference for an administrative tool, is on the MSDN and not on the Technet site. Practical implication is that without being able to use the "Network Service" principal, a distinct network account (domain account or server account) is required for any job that needs to access any network resource. This also means keeping track of another account and password — and taking care of controlling and auditing it's access; whereas the "Network Service" principal cannot normally be used for interactive sessions. Annoyingly, the task scheduler UI also does not tell you that you can't if you try, but rather gives the un-helpful message "Access is denied. You do not have permission to perform the requested operation". The same message is also shown when, for a regular account, the password entered does not match the actual account password. (This happened to me because the keyboard layout on a remote desktop session turned out to be not what I thought it was) Anyone know if the error reporting has improved anything in the new task scheduler?

Wouter, I wonder why you didn't just rsync the whole filesystem over and used it as a chroot, while gradually rolling over services to the actual new system?
Thursday, January 17. 2008MySQL takeover
So Sun has snapped up MySQL. Thinking about the express editions of their SQL database offerings Microsoft, IBM and Oracle released a few years back, to compete with MySQL, I wonder how nervous this news makes them.
I also wonder whether Sun would start offering a default MySQL installation option on their servers. This could make for some more nervosity. Especially if they do it also for their Windows servers... Monday, January 14. 2008Gmail still erratic
Still no solution on the issues I wrote about a few days ago.
Mentions of the problems are surprisingly few and in between; either it's not universal or people just don't notice / are not bothered by it. Saturday, January 12. 2008Big G having issues
Something awry on Gmail this evening... I've been having status messages — you know, the yellow/orangish overlay on top of the page that usually shows when an action has finished — telling me that "the system encountered a problem" for a few hours now while reading my email, intermittently.
Now all of a sudden, I'm dropped in the "old version" of the Gmail interface and there's no longer a choice at the top for the current UI, you know, the one with the funky coloured labels and such; which disappearance leads me to believe that it's not just a client side issue. I'm simply curious now how long it'll take them to fix things. Update As I finished this post and went back to navigating through Gmail, the new UI is back. That didn't take them long... Second update ... but the service also wasn't fixed, I almost immediately started getting error status messages again. And now I'm back into the "old" UI. As I'll be off for bed soon, I probably won't find out how long it'll take. Not that I'm that interested. |
