If you are adding styles or elements (etc. switching textfields with some form of richer editor) this will be visible to the user as flickering.
If you are adding click-events to elements, they will not be clickable until a bit after the elements themselves are visible.

Is there any way to put malicious code into a regular expression?
...As, which all seem to derive from Henry Spencer’s code, suffer severe performance degradation, but where a Thompson‐style NFA has no such problems.
If you only admit patterns that can be solved by DFAs, you can compile them up as such, and they will run faster, possibly much faster. However, it...
How to parse the AndroidManifest.xml file inside an .apk package
This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)?

Why does base64 encoding require padding if the input length is not divisible by 3?
...s are concatenated, it's impossible to recover the original data because information about the number of odd bytes at the end of each individual sequence is lost. However, if padded sequences are used, there's no ambiguity, and the sequence as a whole can be decoded correctly.

operator[] on a vector is only comparable to raw
array indexing in performance
because the entire operator can be
inlined and thus rem...
