If you have du, you may want to check your bill, as you can read about a longstanding issue with fraudulent charges showing up and many users claiming they did not subscribe or solicit those offers.

These charges can frighteningly happen with 0 interaction from the user despite what........

During a migration or other custom setup, it's possible you don't have a $HOME/Desktop and as a result the config file that controls this is set to just use your $HOME directory.

If you get this error, it is often because you have configured Apache with modules that weren't actually installed.

You can read lots of posts about this issue but there is not much information about why this is the case or how grub determines the root= device name. Some even suggest modifying grub.cfg manually which is a disaster as the next kernel update will cause grub to revert back to the device name.

Bonding is an excellent way to get both increased redundancy and throughput. It is similar to the "Network Teaming" feature in Windows.
There are a few different modes but we will use mode 6, I think it's the best of both worlds, as it is not just a failover, but it provides round robin, so you will get redundancy and load balancing. So if you have a 1G single port, you will have a combined throughput of 4G at this point. Just bear in mind that the true thr........

The key is that you need to know the passphrase to do it, if you don't know the password for the key then you can't remove the key since it cannot be decrypted.
ssh-keygen is the easiest method and openssl can be used to manually remove the key and output it to a new file, which you can then copy back over top of the encrypted file.
After that your public key authentication will work without any password prompt because it is no longer encrypted. Make sure you understand........

So it is preferable if you have a single environment that you can create Linux and Windows binaries from rather than running 2 separate........

The code may lead you to believe you have an incompatible template but if you are not trying to use an old template currently that is not the issue. I actually deleted all 3.x style templates to make sure.
What the issue is, is old plugins that are not compatible but Vbulletin does not seem to account for this except that you'll see a fatal PHPerror. You should disable all plugins and then enable one by one until you find the one that is causing the issue.

When things go wrong your video is basically unplayable or the first video plays fine and then freezes when moving on to the next. Generally if both videos weren't produced with the exact 100% same settings you will have issues. You can try the basic concat but it often won't work right.
Solution for me:
My example uses 3 videos in total so "n=3" and a=1 to include audio.

Step #1 from them wipes out the BIOS, but guess what? The step where you restore the BIOS should have been done first, which is sas2flash but no version supports or is able to find my Perc 6/i. So now I'm a bit stuck.
I tried using megarec but it's funny that it can wipe the BIOS but can't forcefully reload it:

One thing to remember is that you need MegaCli to do the flashing.

I've thought for awhile that Asus has been banking on its years old reputation for quality amongst gamers and enthusiasts and I think I'm right. My Asus VE247H Monitor with a supposed 2MS refresh rate has 1 red/stuck/dead pixel but fortunately it can only be seen on a non-true black picture or against a blue screen.
I have several Asus products and find they're all of fairly poor quality. First of all their motherboards have given me the most issues of any brand, they te........
I dread updating the kernel and rebooting to find the Ubuntu graphics aren't working and you have to manually intervene. This is usually because Ubuntu for whatever reason didn't update the drivers you need (eg. the manually compiled Nvidia Kernel driver that MUST be recompiled for each and every kernel update unfortunately).
The most common reason may be that "linux-source" hasn't been installed automatically on my system. I tried to manually reinstall the........
It really is as simple as:
cdrecord -v dev=/dev/sr0 pathtoyourisoimage.iso
-v is for verbose, I prefer it but if you don't you won't see as much output like below (I like to know the details and exactly what's happening)
dev=/dev/sr0 specifies the device name of your burner (they say not to use it and to specify some weird annoying device string but using the raw /dev has always worked for me and is how it should have been implemented from the start IMHO)........
gocr works great and it's simple, just invoke it like so:
gocr filename.png
The output will be printed to the screen.
My only complaint/concern is that even with standard terminal output (not scanned) from a printscreen, gocr does make mistakes by inserting extra spaces where they don't belong, mistaking letters for numbers etc.. but it's definitely enough to be readable and figure out what you're looking at.
I haven't tested yet with scanned input........
The first Hitachi Deskstar 2TB 5K3000 drive I bought arrived DOA for whatever reason (not recognized by the BIOS or OS). Perhaps it was shipping since I bought only 1 hard drive. When I bought 4 through another Vendor, all 4 checked out fine.
I was worried about the RMA process because a lot of people have complained about Hitachi taking weeks to send out their hard drive and almost implied the warranty is useless.
I'm happy to report that my experience was great a........
Have you ever found a website/page that has several or perhaps dozens, hundreds or thousands of files that you need downloaded but don't have the time to manually do it?
wget's recursive function called with -r does that, but also with some quirks to be warned about.
If you're doing it from a standard web based directory structure, you will notice there is still a link to .. and wget will follow that.
Eg. let's say you have files in http://serverip/documen........
I like dd, although it only reads it, usually a read test of the entire disk will uncover if your hard drive is bad in some parts. This is a good thing to do at least once a month, a lot of times bizarre program behavior, laginess and crashing/unnmounting problems etc.. are due to a failing disc and SMART won't know it or indicate a problem:
We must also remember there's never a guarantee, I've found that ever since we moved to larger and more platters per drive with 1TB drives........
I had a dying drive that smart thought until it totally disappeared was a good drive, and actually all parameters did look fine but this system was causing my system to lockup and other bad behavior:

Normally if you're in a certain directory you could do:

I am a huge fan of Linux and the idea of OpenSource but I've said it many times, there are still hurdles in today in 2010 for Linux as a Desktop. Linux is still intended for servers at its very core. This can be changed succesfully though, as Apple has shown us with Mac OS X based on FreeBSD.

example:
dmg2img.c:456: error: BZ_OK undeclared (first use in this function)
dmg2img.c:471: warning: implicit declaration of function BZ2_bzCompressEnd
dmg2img.c:482: warning: implicit declaration of function BZ2_bzDecompress
dmg2img.c:484: error: BZ_PARAM_ERROR undecl........
The dmg format is silly and annoying to work with, why couldn't Apple stick with the .iso standard? Anyway, there's an excellent Linux and Windows based tool to convert it back to a normal .iso Image called dmg2iso
I'll only cover theLinux version although the Windows pre-built binary works the same way.
Download dmg2iso here for free (from the author's website)
It's just silly and doesn't make sense that Ubuntu doe........
As much of a computer nerd as Iam, I'm usually a late adopter to technology for a few reasons. Ifeel most new hyped technologies and electronics are mainly fads, and I'm also cheap.

I've had an old Blackberry for a few years and I was ready to spend some serious cash on a nice Nokia. I love the idea of the Linux based Symbian S60 OS, so I was looking at phones like the E63, E71 (both are basically the same, at least CPU/screensize although E71 is thinner, has a 3MP camera, has GPS, and has dedicated buttons to adjust the volume).
Then Iheard about the N97 and what a revolution it was supposed to be and it was even compared to iPhone.

This will give you the basic info needed to browse and connect to Samba shares from the command line. From the GUI of Gnome or KDE etc, it is pretty standard and straight forward. However, I've found very little guides on how to do it from the command line and if you're like me, a nerd who prefers command line for its simplicity and for remote use, this is the way to go.
First get a list of all the Samba/SMB shares on the target.
smbclient -L hostname........
User username from 127.0.0.1 not allowed because not listed in AllowUsers
What's going on? The user was created properly, it has been defined as having a shell entry and the entry for /etc/passwd and /etc/shadow is set just fine.
This is a new and very smart/secure feature of SSHD. It is simple and yet effective, but also very annoying if you didn't know about it being implemented and that hand editing of /etc/ssh/sshd_config is required to allow a newly add........
