kdenlive is VERY finicky especially if using an older or newer version it can cause crashes, menus not to work, features not to work, things not to work properly.
A good example is that Icould NOT get automask to work, there would be no box to control it until I did this full reset.
One caution is that your backup project files will be erased when doing this:

The idlepc value is very important to dynamips and it is both image and often CPU dependent. There is no "magic"value that will work for all images and all CPUs so this is why I'll show you a quick and handy way.
Also don't be disappointed, some values do not work well but idlepc gives you several. For example in my example below #6 didn't help at all but #7 got me down to about 6% CPU from 99-100%.
1.) Make sure your dynagen config file has........
dd is a very handy tool and there are some more practical things we can do. For example if we want to dump a 3TB drive and want to preserve it and only 200GB are being used on the 3TB we can save a lot of space with gzip.

If you are using the default "Image Viewer" aka Xviewer it seems to die on very large resolution files. It seems to understand to scale them but the printer will try to print and then fail.
Using "Pix" viewer seems to fix this and causes these larger files to print just fine.
Now older versions of qemu-kvm didn't throw this error say if you just had "-video cirrus" when starting qemu-kvm. But newer versions do care.
And this probably only applies to you if you are running from bash/terminal with remote kvm images.
What you need to do is remove the "-video" part and just add -vnc :5
eg. this would fix the error:

This is useful if you have a bunch of images/scans where the same area at the top needs to be chopped.
Sometimes the -trim option (such as the case of white space on top)is wrong and ends up cropping the image and losing some text.
ImageMagick's convert is very useful but tricky to find some things out as I find it to be less than intuitive sometimes.

This is one thing that has me wondering about SMF. It is apparently a known issue but in the latest version and new install nothing looked right because it was using http://127.0.0.1 to find everything! How on earth would it ever do this or think it is normal?
Excerpt of crazy html code it produces that causes the issue:
It has been a big pain for a long-time to install Windows from a Linux environment. I used to run a windows install server and it never worked right for some reason (the install would fail on most servers).

If the file size is too large you need to resize them on the fly:

The resize flag takes a % I have tried without and it seems to take it as pixels and becomes way too small.
You can also play with the "-quality 25" flag to decrease file size even more.........

The above is all there is to it.

I was having an issue with only certain random/jpeg files with the functions imagecreatefromjpeg imagecreatetruecolor and other related ones.
This issue was annoying basically it seems like a libgd issue/bug with newer versions of PHP and it was difficult to trace-out. One very useful thing that helped me was using "php-cgi" and passing the query string as an argument eg:

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

I wanted to Import/Use a .vmdk hard disk image file from VMWare. Generally you can just "point" VirtualBox to it and use it and it will work but I found an exception.
One of my Centos 4.4 x64 images wouldn't boot. I had two copies, an older one and the newer one. The older one booted as normal (once I changed the VirtualBox driver to IDE from SATA). The newer one stopped at the "GRUB loading" message no matter what I tried.

I tried closing all instances of nautilus that were visible and it had no effect.
