PHP 5.2.2 and 4.4.7 Released

“PHP 5.2.2 and 4.4.7 have been released with a plethora of security updates. Many of the security notifications come from the Month of PHP Bugs effort, and range from double freed memory to bugs in functions that allow attackers to enable register_globals, to memory corruption with unserialize(), to input validation flaws that allow e-mail header injections, with an unhealthy sprinkling of other bugs and flaws fixed. All administrators that run any version of PHP are encouraged to update immediately.”

Our sysadmin installed 5.2.2 on our test instances earlier today, and we’ll be testing (and closely watching for external reports) over the next few days before rolling it into production.

parseMe 20070429 Update

Here’s another update to parseMe (back story), my little GPL’ed PHP-based RSS/Atom feed reader for mobile phones and other web-capable devices.

  • Moved to object oriented, pretty much for the “fun” of it.
  • Now passing a custom user-agent in the http query to avoid problems with sources that require it (Digg, among others).

You can find the appropriate links below:

Keeps me from hating my phone until I can afford to get myself a nicer mobile solution.

Fedora Core 7 Test 4 Notes

I installed FC 7 Test 4 on one of my home machines, which was previously running FC6, and it pretty much all went fine. Like with all new releases, there was a definite speed improvement in most operations.

I personally like the new live CD installer. If nothing else, simply for the fact that you get a chance to see how the OS will behave on your new machine before you install it. It’s still ironic to me to see the major distros going to that format, because I remember how most Linux users were poking fun at the first developers to use a live cd install process (that I know of), back in 1999: the now defunct LinuxPPC distribution.

For those interested, you can access a lot of FC7 screenshots and videos at the main wiki: Fedora 7 Tour.

Besides the obvious changes, one that puzzled me for a while since I’m not a hardcore follower up-to-date with all the details, is that all my IDE hard drives were now showing up as /dev/sd* (historically SCSI) instead of /dev/hd*. One quote I could find on the wiki about this was: “In this release, all hard disk partitions follow a /dev/sd* naming convention due to a new libata driver interface in the kernel. The Anaconda installer eases the transition for release upgrades.”

Another puzzler was the fact that despite choosing to setup my box with a manually assigned IP address in the install process, it was still acquiring one with DHCP at boot time. You can see this in the attached screenshot below (click for a larger view): note the discrepancy between the network config panel and the address reported by the ping command in the terminal. This continued, even after rebooting the machine or just the network (service network restart” as root), until I issued a “ifup eth0” command as root, which made it all fine from there on.


Trying to run FC7 Test 4 on my MacBook worked fine natively from the Live CD (no install), which did not under Test 3, but I haven’t been able to boot it while virtualized in Parallels Desktop for Mac. I haven’t tried in VMWare Fusion yet.

The last note is quite a personal one: I much preferred the default theme (icons) in Test 3 (3D) than the ones delivered in Test 4 (2D)… The new ones make me feel like I’m back in the pre-BlueCurve years. ;)

That’s it for me, for now. This box being mostly a file/web/db server, running on older hardware (P4 1.65Ghz), I can’t really play with compiz, which would be one of the major improvements over FC6, besides running new versions of everything.

Update: here are a few notes form a friend who recently installed it on his shiny new Mac laptop: FC7T4 on MacBook (Core 2 Duo).
