comment Mathlink returning wrong output
Sounds like an issue with stray definitions. I can't see any other reason why some symbols should unexpectedly change into something completely different.

Very similar recent question, if not a duplicate: (252956)

comment Count the sequences in an array
It works, and it is faster. Its run time does not seem to be sensitive to whether the input is packed or not, and is 85% that of Michael's in the packed case, and 60% otherwise. (I upvoted before I checked this, because I had faith... but I was not expecting the performance to be insensitive to packing.)

comment Graphs making on Mathematica by using HAM
Even a clairvoyant would have trouble with this question. I vote to close, because no detail is given about what the problem is or in what circumstances it occurs.

comment Faster binary Hamming weight for big integers?
@Mr.Wizard I do not understand that error at all. WolframLibraryVersion 2 is Mathematica 9. I can only assume that there is some problem in Mathematica 10 with backward-compatibility of LibraryLink libraries? Unfortunately, there is not much I can do about it for now. Are you free in the chat to talk about GCC?

comment Faster binary Hamming weight for big integers?
I'm sorry about that. I hope this one will work better. Please let me know whether it does or not. I will need to delete this soon because it is not really legitimate to statically link GNU libgomp (which is GPLv3) into a DLL and then distribute it.

comment Faster binary Hamming weight for big integers?
@Mr.Wizard I will be interested to hear if the DLL runs and what its comparative speed is like on your computer.

comment Faster binary Hamming weight for big integers?
@Mr.Wizard well, shall I just send you the DLL? Here it is. (Virus checked with Virustotal, but exercise your own caution.) Compiled for a Core 2 processor, but should work on anything more recent. (I can help you with GCC another time, if you don't mind. It is quite a complex process.)

comment Fastest way to measure Hamming distance of integers
If you are still interested in this, please see this question and my answer. I realised that you can deal with large integers simply by using IntegerDigits to partition them into machine-size chunks.

comment Faster binary Hamming weight for big integers?
No; I take my comment back. It is the large number of times that BitAnd is called, not BitAnd itself, that leads to slowness. BitAnd by itself works as fast as BitShiftLeft. This will probably be a hazard for most of the bit-manipulation methods you reference.

comment How to tin a soldering iron after unboxing
In my experience, even the very cheapest tips have iron plating, and are not just copper. Filing it will work to rejuvenate it temporarily, but will also result in erosion of the tip after not too long.

comment How to tin a soldering iron after unboxing
Here is a nice video: youtube.com/watch?v=J3OlDsKvzss. It really works. I think this is the best answer as this product is specially made for the scenario described by the asker.

comment Reduce trace width increase thickness with solder
"Ultrasonic" signals, let's say 100 kHz, have a wavelength much longer than the length of any reasonable trace. For example, 200 m. So, no effect will result from that because transmission-line effects are not important until one's signals get into the tens or hundreds of MHz, with wavelengths something close to the track length. The type of solder is irrelevant; all solders have more or less the same conductivity.

comment Problems with SF&F and Seasoned Advice SE CSS
Still does not work for me on Mathematica.SE. Opera 12.17. You could say to use a browser that is not 18 months old, but there is still no good alternative IMO, and imgur's own uploader does work correctly. As of now I have to upload to imgur, pass a link to the StackExchange imgur uploader, and then delete the original image. I am asked if I want to upload the image, but when I accept, the upload never happens. Clicking (I assume this would bring up a dialog to choose the image?) also does nothing.

comment Exporting Dataset to WDX format fails
If HDF5 is the winner, would this mean that HDF5 support in general will be extended? It would be nice if so. HDF5 is very fast and the format seems to be very general, but at the moment its support in Mathematica is only really good enough for storing numerical arrays.

comment Exporting Dataset to WDX format fails
@LeonidShifrin by cross-platform, do you mean Windows/Mac/Linux all running on x86 processors? Or is it really cross-platform, portable to ARM as well? If the latter, I would certainly agree that WDX is functionally obsolete.
