[MYSTERY SOLVED] What does "echo ???????????????" really do?

Posted 04-20-2016 at 08:39 PM by the dsc (linux-related notes)
Updated 04-21-2016 at 05:07 PM by the dsc

It seems to alternate between listing an Nth file (somewhat obscurely related with the number of question marks) on the current folder, or giving some "history" entry, I guess.

That's weird.

Code:
22:54 **ROOT** /# echo ?
?
22:54 **ROOT** /# echo ??
??
22:54 **ROOT** /# echo ???
bin dev etc lib mnt opt run smb srv sys tmp usr var
22:55 **ROOT** /# echo ????
boot home proc root sbin
22:55 **ROOT** /# echo ?????

About Linux For All (LFA)
The system is based on Ubuntu 16.04, codenamed Xenial Xerus and Debian Jessie (Debian 8.4). It’s a total rebuild. I.e. nothing is left of the old LFA system.

The system language is ENGLISH.

Create Images from PDF and recreate PDF from Images...

You might think WTF. But that would be a waste of spontaneity.
Even if the thought has never hit you, this procedure has been useful many times.

Background

My own reasons to convert PDF-files to images, then back to PDF have been
  • PDFs containing unnecessarily huge images
  • PDFs with OpenType fonts which were not correctly embedded
  • PDF content that I did not want to see copied (not easily, at least)
  • PDFs which were originally made from images, that I wanted

CruxEX (CRUX 3.2) live CD/USB with kernel 4.5.1-cruxex and Nvidia Graphics driver 361.42 pre-installed

Posted 04-14-2016 at 03:05 PM by exton (Exton's Blog)
Updated 04-16-2016 at 11:08 AM by exton (MORE INFO)

I have made yet another version of CruxEX.

CruxEX 3.2 64 bit Linux Live CD/USB is based on CRUX 3.2 (latest version, released 151123), which is all Linux enthusiasts/nerds favorite OS. (CRUX 3.2 is a lightweight Linux distribution for the x86-64 architecture targeted at experienced Linux users). CruxEX 3.2 2016 uses the LXDE Desktop environment. I have replaced the original CRUX kernel with “my” special kernel 4.5.1-cruxex, with support for “extra everything”.

Dell Latitude D620

Posted 04-13-2016 at 09:59 PM by shsmith

Hey all,
I got the power supply for the Latitude on Saturday. Nice that it was early, but they didn't send me the one I ordered. However, the one they sent does work, so I'm not gonna complain. The bios does not recognize that a battery is installed, so I guess that is next on the list to purchase. I also want to eventually up the ram to 4GB and get a 1TB hard drive for it. Currently it has 1GB of ram and a 60GB hard drive. I went ahead and put Fedora 23 on it, and it seems to be running...
