See the screenshot below. You can see 2 meta accounts and no SO or any other associated account of mine. Question: My account has undergone lot of issues lately, like de-merger, closing of some duplicate accounts, etc. Is this issue related to that or is there some other problem?

So check this out. I was following up on a question I had asked trying to find an answer to it and found this: My question here: What is ms-hcTest? Is on this site: http://qandasys.info/what-is-ms-hctest/ It was pretty easy to spot (Google "ms-hcTest", both are on the first page). I've seen on...

We are in the early stages of development of the official Stack Exchange iOS app and we need your help with testing. To set a few expectations: there will be bugs, crashes, and missing features, all of which will be fixed in 6 to 8 weeks. We are initially targeting iOS 7 on iPhones only. To ...

I raised this question for a bug, I just noticed that bug was resolved, I tried to add the status-completed tag, but it not allow me to add. Now how do I make a call to add the tag or will I leave it as it is.

To add on to jk.'s excellent answer, you can now pass a method more easily using Lambda Expressions (in Java 8). First, some background. A functional interface is an interface that has one and only one abstract method, although it can contain any number of default methods (new in Java 8) and stat...

Standard troubleshooting rules apply: construct a small bit of code that recreates the problem. I know it's a lot of work, but for really difficult/subtle problems, it's the only way to make any progress.

Is there an x where SHA1(x) == x? I'm looking for a proof or a strong argument against it.

For each of our binary assets we generate a MD5 hash. This is used to check whether a certain binary asset is already in our application. But is it possible that two different binary assets generate the same MD5 hast. So is it possible that two different strings generate the same MD5 hash?

I tried committing files with CRLF-ending lines but it failed. I spent a whole work day on my Windows computer trying different strategies, and was almost drawn to stop trying to use git and instead try mercurial. Please share only one best practice per answer.
