Although I'm quite familiar with Mathematica, I always try to keep an open mind and don't use it as golden hammer. I'm particularly good at things that are fun, for instance

comment Table with multiple iterators running parallel
So lets say you want a list which includes the cylinder number and the angle-shift for each cylinder of your engine, how about: cyl=8;Table[{i,(i-1)*2Pi/(cyl)},{i,cyl}]?

comment Table with multiple iterators running parallel
Let's assume we had this Table which increments both i and r at the same time, so i and r are always equal. Can you tell me only one example where you can create a list with those two iterators which you cannot create with a single iterator? Otherwise, I won't understand what you try to do.

comment Mathlink program with low cpu usage on linux machines only
If your assumption is correct and the copying and transferring of your data into the MathLink program is the problem, then you might think of using the LibraryLink instead of MathLink. There, you can set up C functions that use the data of Mathematica directly without making a copy first. If you are unsure, you might first consider to write a small program for MathLink and LibraryLink to compare whether the data transfer is indeed the problem.

comment Is there any way to automatically evaluate selection in new window or new notebook?
Yes, I guess it should be fairly easy to make a button which copies the currently selected cells, inserts them into a new notebook and evaluates everything. Please look at SelectedCells, CreateDocument and NotebookEvaluate.

comment The front end encountered an error while processing a “NotebookPredictions” packet
I guess Wolfram fixing that bug is the better approach than turning off a highly advertised feature. Otherwise, people might realise that uninstalling the software is another way of preventing the error from happening :-)

comment The front end encountered an error while processing a “NotebookPredictions” packet
Try to find out how exactly you can reproduce the error. A small example where the issue comes up 100% of the time. Then, you click in Mathematica on Help and then Give Feedback and describe what you experience and how they can reproduce it. Don't forget to append a notebook where you store SystemInformation[] so that Wolfram sees your settings.

comment Anti-aliasing not working in Mathematica 10 and Linux
@OleksandrR. No, nothing changed with the latest driver. I have reported this to wolfram, but I always dislike sending them screencasts, images etc. Therefore, I regularly post the issue here and link in my bugreport to this site. Btw, do I have to mention that all the issues were introduced in the final release version of 10?

comment Graphics3D flickers in Mathematica 10 and Linux
@Mr.Wizard Nope. Exactly the same flicker. Btw, per suggestion of Olek I updated the NVidia driver to the newest version. Still the same behavior.

@OleksandrR. Currently updating to the latest. I wasn't thinking of this because in all other Mathematica versions and in the beta it worked.
