• Linux Mint 18 Screen Goes Dark or Black After Screensaver or even when using the Desktop Solution

    You can search for this bug and it seems like it may be related to ecryptfs and is many years old. The symptoms are that you return to the computer and the screensaver was active or the screen was asleep/black and it doesn't seem to come back. But you check by SSH the computer is running fine and are frustrated you'll lose your running programs and have to reboot. There is a simple solution: Ctrl + Alt + F1 Ctrl +Alt + F8 Ba........
  • ffmpeg how to watermark and concatenate in one command

    If you were in my boat you were frustrated that you had to double encode, eg. one separate encode for watermark and a separate from concat and it's not easy to figure out this with ffmpeg on your own. However it is a nice way to save time! ffmpeg -i file1.mp4 -i file2.mp4 -i file3.mp4 -i watermark.png -filter_complex "[0:v]setpts=PTS-STARTPTS[v0]; [1:v]setpts=PTS-STARTPTS[v1]; [2:v]setpts=PTS-STARTPTS[v2]; [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[v][aout]; [v][3:........

  • Asus VE247H 23.7" Inch LCD/LED Backlit Monitor Dead/Stuck Pixel Policy Complaint

    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........
  • htaccess modrewrite problem with rewriting url with- dashes solution

    I was getting frustrated with trying to write a simple URL like this: /example-withdash I used the htaccess code like this: Rewriterule ^example-withdash$ / [R=301] I also tried escaping the dash which I thought should have treated it as a literal but that didn't work either: Rewriterule ^example-withdash$ / [R=301] But it wouldn't work, apparently the "-" dash means don't substitute,........
  • Convert PDF to JPG/JPEG without low resolution/small picture size

    convert -density 400 somepdf.pdf -scale 2000x1000 output.jpg The key is the "-density 400" switch and also -scale 2000x1000 To give credit I found the solution here: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=10928 That was the perfect solution when I was frustrated with how small the resulting JPG's resulted. I'm sure this will help a lot of people when it comes time to converting a PDF to JPG which I'm amazed Imag........
  • Ubuntu 10.04/GRUB2 mdadm won't boot

    Moving to RAID was a pain. What you have to do is the following from an existing install: Install mdadm Create your mdadm RAID 1 array on your spare hard drive. Start it with the missing disk. rsync the entire contents of your current / to the md partition. Here's a good way of doing it: rsync -Pha --exclude=/proc/* --exclude=/sys/* --exclude=/mnt/* /. /mnt/md2........
  • Centos 5.5 RAID 1 boot issue

    I installed 5.5 with a 300GB RAID 1 partition (boot is also on this partition). It booted up fine the first few times until after I used a Live CD and accessed the array, and it became named /dev/md127 for some reason. Now whenI boot into CentOS I get a kernel panic and different errors, once I got "invalid superblock", even though the array is fine (it didn't happen again, probably because I was sure to dismount and stop the mdadm array properly). Here's what........

  • iPhone Enable Tethering Manually Update ipcc Carrier Settings/Update via SSH

    Everyone says there is a "manual" way of doing it and then they tell you to use iTunes, but if you're like me, you're travelling on business in a foreign country and your laptop does not have iTunes and you don't have a way of getting it and/or don't want it. For this example I'm using the provider "du" in Dubai, UAE (United Arab Emirates) but this method works for virtually all providers. The requirements in this case to truly "manually update........
  • Apache Ignoring/Not processing .htaccess file

    I was getting very frustrated one day wondering why it appeared my .htaccess file was being ignored and not processed by Apache. No matter what I did it was obvious that Apache didn't care about my .htaccess file. Then I realized that the default settings must be in effect, which is that my vhost didn't explicitly allow me to override the default settings. This usually comes down to your vhost settings. Make sure you have an entry like this in your Apache vhost settings in........

    This is unfortunate and frustrating as many sites use it, a lot of people are frustrated that TinyMCE does not work on the iPhone Safari browser. Apparently the developer of TinyMCE's answer is "talk to Apple about it" It's really frustrating although, I wonder if any other mobile phones are able to use TinyMCE or not, whatever the case is it would be nice to find a solution to use TinyMCE on the........
