2013-07-05 06:34:26 -0500 answered a question how to free up 253 megs?

You could use a LiveCD or LiveUSB (maybe the one you used to install Fedora), and get gparted (su -c 'yum install gparted') to resize the partitions you assigned for / and /home. Shrink first /home by 7 GB, then grow / by those 7GB.

In my experience 12 GB is an affordable size for / and don't worry too much for applications installed.

Gparted is going to take a while, but not too much.

I'd recommend you take a look at this question: it even suggests a way to link this to shutdown.

2013-07-05 06:22:25 -0500 commented answer Clean Temp files

This one combined with the solution proposed by Rajat would be a nice one. However, beyond F12 is pretty old, would you like to elaborate a bit on why don't you recommend this approach?

2013-07-05 06:20:22 -0500 commented answer Clean Temp files

I really like this one, read on tpmwatch but it doesn't do anything find + rm as in this example can't do.

2013-07-05 06:15:58 -0500 commented answer Clean Temp files

This is the way fedora is configured out of the box at this moment, however "enough RAM" is not an useful parameter and actually is giving a lot of trouble.

2013-07-05 03:28:33 -0500 asked a question Any mistakes/bugs you can spot on this /tmp reallocation?

Background: Yesterday I've got a lack of space in /tmp. I don't know the whole background for deciding /tmp to eat my whole RAM space with tmpfs, but I was being unable to run even shell autocompletion, and any new application was very slow (running $ free it showed use of swap growing to almost 90%). Having tinkered with debian systems for disk-space allocation, I thought it'd be painless creating a dedicated partition for /tmp and putting /etc/fstab to automount it.

So wrong... my ext2 partition for /tmp was mounted but I had no permissions, I noticed on tmpfs was mounted with mode=1777 (sticky bit, rwx for everyone, right?), but ext2 had no this option, so I choose to go with ACL for permissions and chmod for sticky bit:

sudo setfacl -d -m u::rwx /tmp

sudo setfacl -d -m g::rwx /tmp

sudo setfacl -d -m o::rwx /tmp

sudo setfacl -m g::rwx /tmp

sudo setfacl -m o::rwx /tmp

sudo chmod +t /tmp

This solved the issue with permissions and lack of space on /tmp, and the use of RAM and swap descended noticeably (less than 50%). However trying to start today apache to start a new project, SELinux blocked the search access on /tmp and I didn't liked any of the solutions proposed by the alert browser.

I don't want to disable SELinux, however its guide on docs was too much theory and almost no advice, instead this howto suggested in other question did the click on my head, and without rebooting my system with autorelabel I'm running now on /tmp without more blocks from SELinux:

$ sudo su

# restorecon -Rv -n tmp #in order to check what was going to be done

# restorecon -Rv tmp

The last bit in this history is:

After reboot, df reports /tmp still mounted with tmpfs filesystem, but mount reports it is mounted on my ext2 partition.

Thanks in advance for your input on this.

2013-07-04 22:31:59 -0500 commented answer Best way to integrate web browser with local databases and scripts?

Why do you say is a bad idea? I have several sites backed and shared with some friends, forever lost in the web and not even available in wayback machine. I've also installed lots of education sites in PCs without even LAN, in order to share it with children without ways at this moment to plug into web.

There are a lot of sites still needing flash player and not only youtube, #fwiw

2013-07-04 20:51:25 -0500 commented question ssh permission denied with correct password

A common mistake I've faced is firewall blocking incoming connections to port 22.

2013-07-04 20:28:43 -0500 commented answer how to securely and permanently delete a file?

This is actually a good option on solid state media like USB pendrives, however I wonder if forensics software like Photorec [1] could recover the "erased" file in this type of media.

It's interesting too scrub, and very useful if you want to, well, scrub deeply a file, a whole partition/disk before creating an encrypted partition, or your free space. And it is actually very fast.

2011-10-04 01:38:32 -0500 asked a question Which are the most used DocBook tags actually used by you in Fedora Guides?

I bet many of you have written some chunks of Fedora Guides in DocBook. Maybe even you have edited significative chapters (or whole books ;-)).

Would you like share with the crowd, your most loved tags?

Let's say, for example, nobody can feel how is like learning functional programming without knowing about really fun things like: map, folds, lambdas, list comprehensions, and so on.

Do you think we can arrange a list like that for DocBook?

In my humble opinion I bet it can't be that interesting just turning the most used HTML tags like <p>, lists and links, into more verbose equivalents. Or attribution tags to Meta properties.

Maybe you could enlighten wannabe doc-writers, showing us the most interesting tags, the first subset every new doc writer must to learn, to avoid cheating using pandoc ;-) to compose from markdown and turning it into docbook to let people engage in translation.
