The name Zmeu (no capital E) is the name of a fantastic creature of Romania. There are so many stories that there isn't a clear understanding of what it is... but it is human like, can spit fire and wants to marry young women.
If you're wondering, it is generally a bad guy.
Today, I noticed a lot of traffic on one of my servers. Looking into what was happening, I immediately found out that an attacker was looking for a loophole in that system. That attack was being performed from China.
Oka, so today I finally got the chance to upgrade to Ubuntu 14.04, hopefully soon to 14.10 too.
I have to say that in general, it looks like they've done a good job as things seem to work better...
However, the display setup got lost. My HP 2509m monitor is connected through a KVM and because of that, it does not always work as expected. That is, the nVidia card does not get to read the monitor information. It took me a while, but I found a way to fix the problem.
First of all I connected the monitor directly to my computer. That gave me the ability to change the resolution to 1920x1080 ...
Once in a while I want to add my user to a group and then right away make use of that group.
Unfortunately, in general Unix kind of forces you to re-log in for the new group to be attached to your account.
However, a command has been added, a while back, to do just that on the fly. Not something you would want to use in a script, but at least, it works for me when doing a few things here and there.
In my case, I wanted to run QEMU, which I hadn't done in a while, and the system told me that it could not open the KVM, the error: kvm permission denied.
The problem was that I was not part ...
Installing SugarCRM is generally easy, but if you don't want to just make everything writable by Apache, you may find it tricky, especially if you have problems setting up the system.
First of all, you want to get the code from SourceForget.net and extract it in the root directory of the website where you want to use it. I prefer to dedicate a sub-domain name such as crm.m2osw.com to make use of SugarCRM. That way I don't have to deal with other weird things of using this under a sub-directory.
Once in there, the user and group should be a user other than ...
Today I noticed many errors on one of my websites. Looking closer into it, I noticed that the code for the mo_references Drupal module stopped working.
It took me some time, especially because the code seemed to work just fine as all the files could easily be displayed.
Actually, that was not the case. The unpack() character 'a', which I used, was transformed from a simple string that gets trimmed, to all the characters, including the NULL characters. Ouch! Now we have to use the 'Z' character instead.
I use it to unpack() a tar file by loading 512 bytes of data in a ...
That box is heavily tweaked with the CSS assigned to it, as well as all of its neighbors. So I thought that may have something to do with it.
What I hadn't realized so far is that the ready() function of jQuery() is called once the script that includes it is ready (as in loaded) and not once the document as a whole is ready (done loading, i.e. onload event.)
With that knowledge it was easy to understand that I was actually finding myself ...
As I upgrade to 13.10 of Ubuntu, I'm having to do work to get my system back to normal...
Today I stumble on the fact that USB ports are now not accessible by everyone by default. So when I tried to scan a document, it told me that I had no scanner. Panic... and then I found out that the permissions were changed, widely, so only users who are root (by default) can access the scanner.
I changed the group to a group I'm in and it worked without having to reboot or relog in. However, it is not unlikely that the group won't stick... TBD!
To find the USB port that has your scanner, ...
As I was looking around for the way to specify the correct key for launchpad, I could not find it. Luckily the ssh process is running when it asks for the passphrase so I could see the URL used to access the launchpad server from Bazaar. It is:
The address is not visible by default because you use the lp: protocol instead of a full URI to access launchpad.
Host bazaar.launchpad.net HostName bazaar.launchpad.net User <your launchpad username> PasswordAuthentication no HostbasedAuthentication no IdentitiesOnly yes IdentityFile ...
Today I opened a document where I had to make a few edits and LibreOffice decided to tell me:
Readonly content cannot be changed.
No modifications will be accepted.
There is a screenshot of that message:
The error may be justified, I do not know, but apparently not too many people know how to unlock a document. I found pages and pages that tell people to check the read/write protection of the file, as if a read-only file on disk could not be updated in the editor... (yes! you cannot write it back, but you can edit it and do a Save As ...)
One person, though, had the correct answer to ...
One thing that I find annoying in gvim is the foldcolumn parameter which is not reset once you are done with a diff process.
Of course, gVIM does not really know when you are done diff-ing, so its behavior makes sense... only it is still annoying.
To remove the fold (2 gray columns on the left used to hide areas that match in each file) you simply have to set the foldcolumn parameter to zero:
Just in case, you enter a diff from within vim by loading two files, then using;
The diffsplit can specify any buffer number, I use the # as the other buffer (the ...

A hard drive is a device that save a large quantity of data for later recollection.
Most hard drives today use a magnetic system to save the data. However, those do get really hot and tend to break easily because they use a mechanical head (after 4 to 5 years.) Yet, they have an incredible capacity with drives that can hold as much as 2Tb.
New modern drives use flash technology. This is like your USB thumb drive. It does not get hot, it is silent, it has much faster read access (no head to move.) It has two drawback: (1) it has a rather slow write and (2) the capacity is still quite small (at time of writing we are starting to get 128Gb drives...) The price is also much higher, but if you consider that these drives will probably last you twice as long as the magnetic drives and you won't need extraneous cooling systems, overall, it probably still worth it.
