IR Remote for Nikon

I didn't buy this for my Film SLR because I cost too much. Currently Nikon's brand (ML-L3) costs $15 on Amazon/Adorama etc. and on Nikon Mall costs $20. However, if you look here (bestofferbuy) you can get an 'alternate version', called the YN ML-L3, for $4.80 and free shipping. I was a little wary at first and wondered if this was a scam, but I decided to try it out and ordered two (aha, see how this works, they price it less and that gets the sucker customer to buy more). I guessed it would take a long time to get here, but it took about a week and a half. I tried out the first one and it works fine. The unit comes with battery installed but with a plastic tab to keep it from discharging. These shady Chinese operators are moving upscale. (Actually it ships from Hong Kong. Don't know if that's any different anymore).

I have plans for the other one. An intervalometer costs an insane amount of money. Say like $140. What I want to do is order a 555 and some pots from Digikey and modify the second remote for time lapse photography. Who knows, I may even get fancy and use a crystal and a binary decade counter with BCD encoding for accurate timing...

Remove field code from Word document

e.g. before submitting a MS, or hand manipulating some formatting because Word does things (like cross-references) so half-assed [from here ] Select all the text (CTRL-A) Press Ctrl+Shift+F9 Editing to remove anonymous comments that only contain thanks. I really appreciate the thanks, but it makes it harder to find comments that carry pertinent information. I'm also going to try and paste informative comments in the body of the post to make them easier to find.

h5py and multiprocessing

The HDF5 format has been working awesome for me, but I ran into danger when I started to mix it with multiprocessing. It was the worst kind of danger: the intermittent error. Here are the dangers/issues in order of escalation (TL;DR is use a generator to feed data from your file into the child processes as they spawn. It's the easiest way. Read on for harder ways.) An h5py file handle can't be pickled and therefore can't be passed as an argument using pool.map() If you set the handle as a global and access it from the child processes you run the risk of racing which leads to corrupted reads. My personal runin was that my code sometimes ran fine but sometimes would complain that there are NaNs or Infinity in the data. This wasted some time tracking down. Other people have had this kind of problem [ 1 ]. Same problem if you pass the filename and have the different processes open individual instances of the file separately. The hard way to solve this problem is to sw...

Reading spreadsheet data in Python: The lack of a good ODS reader

I try and keep long term data in as simple a format as possible, which means text where ever possible. In earlier times I would enter data in excel spreadsheets and then read them from my Python programs using the xlrd package which is excellent. This works well, but in the back of my mind is the thought that someday Microsoft might do something funny with their business model making office software more janky to use and all my fears about keeping data in proprietary formats would come true. Oh, look, that day is today . So, I'm completely abandoning the MS Office suite and going back to basic text files. However, there is a tension between keeping tabulated data in a simple form, such as csv, and entering it in a convenient manner. Excel, of course, nags you everytime you edit a csv file and save it. Libreoffice is excellent: it handles loading and saving in a very streamlined fashion. However, every time you open up the csv file you need to tell Calc what widths you want...
