ColdFusion is Painful. Stop Using It.
Posted by Double Compile on Tuesday, November 17. 2009
I'm a software engineer with 10 years (at the time of writing) under my belt, and my speciality is web-based applications. I have used a number of platforms to author applications of all sizes. I am an expert in PHP. I am advanced Java EE developer (and Groovy). I have used ASP.Net. I have also used ColdFusion. (To a lesser extent, I have used Perl and Python, but only once each and it's been years). I am comfortable saying I have enough experience with those platforms to give ups and downs.
The purpose of this article is to lay out the downs of ColdFusion, for in my opinion, it has few ups. To quote a comment in this blog post, "Coldfusion indeed sucks major spidermonkey testicles." This post is not a reasonless rant; I have many reasons listed below that ColdFusion should be avoided and they're pretty good. This is not another "ColdFusion is a dead language" post. Far from it, I know ColdFusion is still alive and kicking, and that is a sad truth.
GRUB error 24 in Ubuntu Karmic and the fix
Posted by Double Compile on Thursday, November 12. 2009 in GNU/Linux
I applied a bunch of updates to my installation of Ubuntu 9.10 Karmic Koala this morning. Let it be known that I upgraded to Karmic from a clean install of Jaunty, and my root partition was once an ext3 file system turned into ext4. I returned from taking a shower to find the system had completely locked up, so I rebooted. Anyway, I got just past GRUB and received the following error:
24 : Attempt to access block outside partition
As it turns out, the GRUB Manual gives the following as a possible reason.
"This error is returned if a linear block address is outside of the disk partition. This generally happens because of a corrupt filesystem on the disk
So I inserted the Live CD and ran fsck.ext4 -f on the device in question, and no errors were found. Peculiar.
Some Google searching turned up this Launchpad issue, which in turn pointed me to a blog post called "Grub voodoo error no 13/24 and how do i fixed it" for a possible fix.
Allow me to quote from that post (thanks so much, Marius) the correct procedure to fix this beast in case anyone else runs into this little problem. Fill in /dev/sda with the correct device name for your disk containing the root partition.
$ sudo su $ mount /dev/sda1 /mnt $ mount --bind /dev /mnt/dev $ mount --bind /dev/pts /mnt/dev/pts $ mount --bind /dev/shm /mnt/dev/shm $ mount -t proc none /mnt/proc $ mount -t sysfs none /mnt/sys $ grub-install /dev/sda --root-directory=/ --recheck
I rebooted and everything was fine; crisis averted.
