I have been using mysql-devel-5.1.69-1.el6_4 from yum, and in the last day the only available option I can now see is mysql-devel-5.1.73-3.el6_5. Is there a way to get the older version from yum? Is this a regular thing to remove older versions? I would prefer to use the older version because I know it will work with my other libraries/code.
Many repository mirrors only mirror the most recent updated packages because that's what most people need and the disk space for older versions can be high.
If you really need a specific version (and I would generally suggest that you do not and should not rely on a version like that whenever possible) you should be able to get the older package from http://vault.centos.org .

I'm working on upgrading our product's MySQL version. MySQL documentation states that Upgrades between milestone releases (or from a milestone release to a GA release) are not supported
I'm trying to determine if the version path we're traversing is not supported (5.5.30 to 5.6.26).
It isn't clear on their archived release page how to distinguish a GA from a milestone build. Is there a place with additional information about each release? If not how can I tell the difference?
Check the Release Notes.
Version 5.5.8 and all later versions are GA in MySQL Server 5.5.
Version 5.6.10 and later versions are GA in MySQL Server 5.6.
Non-GA releases are the versions prior to these, which shouldn't be used in production, because (among other reasons) there are sometimes breaking changes prior to GA. Once the series goes GA, these are not supposed to happen.
Note that there's a difference between "not supported" and "impossible." In MySQL compatibility parlance, "not supported" sometimes means "if you read and understand the release notes for each and every intermediate version, know exactly what you're doing, proceed deliberately, and take appropriate precautions, it might work just fine, but don't say we said it might work just fine, because we didn't say that." In other words, it's literally not supported in the sense that failures on such paths will not be considered to be something that merits a remedy or fix or workaround.
Found a similar question about the difference between QAPlug-FindBugs and FindBugs-IDEA, but not about CheckStyle...
I think (from previous experience) with these plug-ins that one difference is that the QAPlug's CheckStyle version seems to be behind the CheckStyle-IDEA's CheckStyle version (I'm not referring to the versions of the plug-ins, but of the version of CheckStyle that's embedded in them).
Anyone knows of any other differences between those?
Advantages of CheckStyle-IDEA over QAPlug – Checkstyle:
Newer version of Checkstyle used
Community on GitHub
Fast scan before commit
Support for multiple configurations
Support for third-party checks
I haven't noticed any use case when QAPlug is better.
Backward compatibility means (as I understand it) that newer versions of the code will:
Still be able to read data written by older versions
Still be able to operate with older versions using some network protocol
Basically, nothing will break when I upgrade a system to a newer version, even if it is just one part of a larger system, or uses resources created by the older system
But what is "Forward Compaitible"?
Forward compatible bascially means that the code will be compatible with newer versions of the software. In other words, code you enter now will smoothly transition to the next software version. You could also think of it that the next version(s) of software will be reverse compatible with the current version.

Backward compatibility vs forward compatibility
We have two versions of a software: the version A, and a newer version B. We say:
B is backward compatible with A if everything that works on A will still work on B.
A is forward compatible with B if everything that works on A will still work on B.
B is backward compatible if it is backward compatible with all the versions < B.
A is forward compatible if it is forward compatible with all the versions > A.
I have updated to a new bios version which is probably corrupt. Now I can't fall back to an older bios version because the build date always has to be newer than the currently installed bios.
Is there a safe way to manipulate the build date? In windows it is called "Date modified"
Okay never mind I just figured it out by myself. I just had to re safe it.
I need to check a bug in Google Chrome for specific version like 14.0.802.30. How can I get the pervious version for that? Also, how can I switch off automatic update functionailty of Chrome?
Some old Chrome-Versions can be found on oldapps.com if you can't find the version there, you can maybe use the corresponding Chromium release? Its basically Chrome minus the Google-Spyware. For Operating Systems other than linux you have to build your own version tough (easy to follow instructions are published on the website).
Chromium-Releases can be found here
