Samsung Microwaves 5E or SE error on display

Submitted by Druss on Tue, 2017-09-12 18:59

So, when I got home yesterday, I found that my Samsung microwave was beeping frequently for no apparent reason. Switching it off and back on did fuck all and occasionally I'd see the clock display read "5E" or "SE". This issue didn't go away even after a few hours and I'd resigned myself to having to go through the rigmarole of calling a service center and getting this fixed which would undoubtedly involve charges amounting to a good chunk of the microwave's original price. Of course, that wasn't what I did.

I just ran into the following error while trying to commit (a previously working project) in Eclipse Neon:

Aegir: Site backup error "Could not back up sites directory for drupal"

Submitted by Druss on Sat, 2015-12-19 18:08

If you encounter,

Could not back up sites directory for drupal

when trying to back up a site using Aegir, then this is because there are some permission issues with some of the files in the sites directory.

In my case, these files were in the private/temp/ directory. Listing all offending files can be done by the following command:

MongoDB on Linux with pecl "configure: error: Cannot find OpenSSL's libraries"

Submitted by Druss on Sun, 2015-12-06 21:29

Edit: Skip this and scroll down for a proper fix!

Just tried installing MongoDB support for PHP on Kubuntu 15.10 via pecl and ran into the following error message which caused the installation to fail:

configure: error: Cannot find OpenSSL's libraries

While this can probably be fixed using some magickery, in my case, I did not want SSL support on a dev server. I just wanted to get the fucker up and running. To this end, I discovered that the issue was that I was using:

Eclipse: Cannot create project content in workspace.

Submitted by Druss on Mon, 2015-09-07 21:48

If you run into the following error while adding a project into Eclipse from existing source using the New Project dialog,

Cannot create project content in workspace.

then you are very likely trying to create a new Eclipse project that contains Eclipse metadata files from a previous Eclipse project created at the same location. The fix for this is to import this pre-existing project into your workspace using the Import, General, Existing Projects into Workspace option.

Sed: invalid reference \1 on `s' command's RHS

Submitted by Druss on Mon, 2015-07-06 13:46

If you see something like the following error message when you run a sed command:

invalid reference \1 on `s' command's RHS

then it (probably) means that your regex capture group has not been escaped properly.

So, if you are using a command like:

sed "s/foo(bar)[123]/baz\1/"

then it needs to be escaped like so:

sed "s/foo\(bar\)[123]/baz\1/"

In other words, round parentheses/brackets need to be escaped while the square brackets do not :|

Microsoft Virtual CD-ROM: vcdrom.sys "Driver has been blocked from loading"

Submitted by Druss on Tue, 2015-06-23 16:12

I had the misfortune of trying to install Microsoft's "Virtual CD-ROM Control Panel" which creates, well, a virtual CD/DVD-ROM drive that allows you to mount ISO images. There are a number of other programs that do this, but seeing as to how this was a M$ product, free, Window-7 compatible, and light of weight, I decided to give it a whirl. The README.txt that accompanies the installation file provides instructions for the manual addition of the vcdrom.sys driver to the Windows directory.

C# error: InvalidOperationException: Collection was modified; enumeration operation may not execute.

I was fiddling around with Unity3D (and C#) and I ran into the following error messages:

InvalidOperationException: Collection was modified; enumeration operation may not execute.

MySQL: #1071 - Specified key was too long; max key length is 767 bytes

Submitted by Druss on Fri, 2015-04-03 01:33

Here I was simply creating a MySQL (5.5) table when suddenly up pops the following error:

#1071 - Specified key was too long; max key length is 767 bytes

After a little trial and error, I found that since one of my VARCHAR fields was being used for a UNIQUE index, MySQL was basically telling me that it was using too much space. When I reduced the length of this field from its initial 512 setting to 256 & then 255, it still complained. However, reducing it further to 128 fixed the issue!

Desktop effects were restarted due to a graphics reset

Submitted by Druss on Wed, 2015-02-04 01:43

While using Google Chrome on Kubuntu 14.10, the display hung for about 5 seconds before unfreezing with the following notification:

Desktop effects were restarted due to a graphics reset

Once this began occurring with an increasing frequency, I began to do a little digging. Looking through /var/log/kern.log brought the following up:
