[ "Git/svn - keeping synced two repositories with different access rights", "There is just too much information online for me to understand and be able to get my own picture, so I gently ask the community to provide light to my journey...\n\nMy situation:\n\n\nwe have a SVN server behind a firewall within our company. Impossible to move to DMZ.\nwe need some third party (our client) to access part of the source code from a remote location, since they are contributing to the development. BUT they are not from our company, so I cannot provide them VPN access. I need them to be able not only to read source, but also commit changes.\nour SVN repo contains ALL our product. I want to give access to ONLY some folders to my client.\nMy company is VERY reluctant to let us buy a private GitHub account... for security reason, not cost...\n\n\nWe are trying for a few months the following, but it just doesn't work since it requires manual sync:\n\n\nrent a virtual machine online. Install a Git server. provide access to both our developers and our client.\nmake an initial checkout of the reduced number of svn folders I want to share.\nWe all work: either improving the code in these folders or creating new source code and folders.\nour developers are supposed to update/commits the two repos by hand... And this just does occur...\n\n\nSo I'm looking for solutions to automatically sync, but keeping in mind the access rights...\nI've seen this... Would it work for me? http://git-scm.com/docs/git-svn \n\nAnother worry is that our company will during next year migrate all our SVN to Git...\nI have no issue in anticipating this and running our own git server instead of the SVN, but it will have to be kept behind the firewall. Then I'm lost with the \"clone\", \"mirror\" aspects and to maintain the correct access rights...\n\nWhat solution/advice could you provide us in terms of this distributed architecture?" ]

[ "Interview data in Python: Count a certain co-occurence separated by speaker", "This is a social scientist asking. I think I found the first perfect use case (for me) to use Python, but I'm not there yet. I would like to analyze hundreds of formalized interview transcripts, in fact, the basis are protocols of parliamentary debates. It could also be a random interview. I would like to count certain words -- the \"cheers\" every party gets, ordered by parties --, but as a newcomer to Py I'm struggling to find the correct formula to define the conditions. Simply put, I'm interested in the following research question: Who is cheering whom? There are a few \"if's\" that I would like to be taken care of to produce the desired outcome. \n\nThe raw data is complex, but well ordered.\n\nEach discussion is ordered by speaker, who's formally introduced by: \"The floor goes to... X\". Then there's the speaker's text, there are also blank lines separating the text. When the speaker is finished, the next one is introduced with the same phrase. During the speech members of certain parties \"cheer\" the speaker, which is indicated in the data bei \"(Cheering ... PARTY NAME).\" These entries can go over 1 or 2 lines. And I would like to count these \"cheers\". \n\nHere's an example of the raw data (simplified): \n\nThe floor goes to member of the parliament Muller by the\nLeft Party.\n\nBla bla\nbla \n(Cheers Left Party, Green Party, Blue\nParty )\n\nBla\n\n(Cheers Nazi Party) \nBye Bla\n\nThe floor goes to member of the parliament Tsing by the Green Party.\n\nBla bla\nbla \n(Cheers Left Party, Green Party)\n\n\nHow do I tell Python to loop through text that follows after a certain string in a certain line (the speaker) has occured? Plus, how do I count co-occurences in a line, thus skipping empty/irrelevant characters (counting the \"cheers\")? Using a basic word count code I was able to count all the cheers in a file, but that's just a simple start.\n\ncount = 0\nfhand = open('3_parliament.txt') \nfor line in fhand:\n line = line.rstrip()\n if not line.startswith('(Cheers '): continue\n words = line.split()\n count = count + 1\n print(words[1]) \n\nprint(\"There were\", count, \"lines in the file with >(Cheers< as the first word\")\n\n\nI found additional example code where \"paragraphs\" were defined, but this does not work here because of the empty lines, and the complex nature of the text in general. textwrapping seemed to produce similar issues. I also find it challenging to count co-occurences in a line (\"Cheers ... Party X\". Do you have any tipps or hints?\n\nI'm using the latest Python 3.8 on Win 10, via Atom." ]

[ "How do I find all elements of an numpy array less than a value but with completely unique indecies?", "I am working on a particle-particle annihilation problem. In this problem, any particle closer than some distance, r, to another particle will annihilate with that particle. The issue (as well as a few others) is that some particles are closer than r to more than one other particle. So I have to figure out which specific particles i to annihilate with particles j such that no particles annihilate more than once. Ideally this is all done in numpy.\nSuppose we have two 1D arrays x and y which specify the position of N particles. The pairwise distance between all particles may be calculated like\ndist = np.sqrt((x[:,None]-x[None,:])**2 + (y[:,None]- y[None,:])**2)\n\nwhich yields a 2D Hermitian array of shape (N,N). This array can easily be sorted, d_sorted = np.sort(dist) to find the shortest distances between particles. However d_sorted cannot merely be index-culled of all values less than r because some particles have more than one pair-distance less than r.\nSo, how do I find all elements of the dist array less than a specific value such that the (i,j) index collection of the resultant elements has each i,j being unique and no element of {i} being in {j} or vice-versa?\nNote, I initially thought careful application of np.unique would solve my problem, but I was unable to get anything worthwhile." ]

[ "C# Exiting a Console Application Without Exceptions", "I'm using a C# library that has a pretty bad shutdown procedure and whenever I exit the application using Environment.exit, it throws an exception and my whole console application freezes with a popup message (debug/close/etc). I am running my application as a scheduled task so I'd prefer not to have to manually hit the close button every time it runs and crashes on exit. I've tried putting some try catches around it, and handling all exceptions, but it doesnt seem to work.\n\nIs there a way to force an application exit and not allow any exceptions or anything that will cause it to crash?\n\nThanks\n-Jeff" ]
