"Split string on multiple delimiters of any length in Haskell",
"I am attempting a Haskell coding challenge where, given a certain string with a prefix indicating which substrings are delimiting markers, a list needs to be built from the input. \n\nI have already solved the problem for multiple single-length delimiters, but I am stuck with the problem where the delimiters can be any length. I use splitOneOf from Data.List.Split, but this works for character (length 1) delimiters only.\n\nFor example, given\n\ninput \";,\\n1;2,3,4;10\", \n\ndelimiters are ';' and ','\n\nsplitting the input on the above delivers\n\noutput [1,2,3,4,10] \n\nThe problem I'm facing has two parts: \n\nFirstly, a single delimiter of any length, e.g. \n\n\"****\\n1****2****3****4****10\" should result in the list [1,2,3,4,10]. \n\nSecondly, more than one delimiter can be specified, e.g. \n\ninput \"[***][||]\\n1***2||3||4***10\", \n\ndelimiters are \"***\" and \"||\"\n\nsplitting the input on the above delivers\n\noutput [1,2,3,4,10] \n\nMy code for retrieving the delimiter in the case of character delimiters: \n\n--This gives the delimiters as a list of characters, i.e. a String.\ngetDelimiter::String->[Char]\ngetDelimiter text = head . splitOn \"\\n\" $ text\n\n--drop \"[delimiters]\\n\" from the input\nbody::String->String\nbody text = drop ((length . getDelimiter $ text)+1)) $ text \n\n--returns tuple with fst being the delimiters, snd the body of the input\ndoc::String->(String,String) \ndoc text = (getDelimiter text, body text)\n\n--given the delimiters and the body of the input, return a list of strings\nnumbers::(String,String)->[String]\nnumbers (delim, rest) = splitOneOf delim rest\n\n--input \",@#\\n1,2@3#4\" gives output [\"1\",\"2\",\"3\",\"4\"]\ngetList::String->[String]\ngetList text = numbers . doc $ text\n\n\nSo my question is, how do I do the processing for when the delimiters are e.g. \"***\" and \"||\"?\n\nAny hints are welcome, especially in a functional programming context."

Will it still be feasible to migrate to the Identity system without losing any data?\n\n2) As I'm using EntityFramework so DbContext is needed to migrate to Identity system. Can I use ObjectContext for ASP.NET Identity migration?\n\n3) I'm NOT using all the Membership tables as listed at http://i1.asp.net/media/48109/image006.png?cdn_id=2014-11-11-001.

"Strategy for reusing GWT DatePicker in Javascript algorithm",
"in my GWT application I use a Javascript library to provide users with a SQL Where string builder capability - used to support 'advanced search'.\n\nThe javascript sources currently just provide a plain html text field for the date. If I was in pure JS I'd incorporate one of the many 3rd party date selector libraries.\n\nBut, I've already got the GWT date-editor there in the client (to support other UI capabilities).\n\nCan anyone recommend a strategy for incorporating the GWT popup editor in my legacy javascript? Because of GWT compiler obfuscation I don't think I can reliably predict the name of the GWT date editor component classes.\n\nI suppose it's a balance between pushing the config from GWT, or pulling from the javascript sources.\n\ncheers,\nIan"

"Differences between Screenlog and Hardcopy on GNU Screen",
"Introduction\nI'm new using GNU screen, and I'm using it mostly because I don't want to lose my work if unexpectedly my SSH connection closes, and also because I want to keep a logfile of every output printed on my terminal (at least some recent tracks)\nFor SSH stuff, I guess Ctrl+a d to detach and screen -r or screen -r session_name to re-attach to some session solve all my problems, now I'm trying to understand logging.\nI found screenlog and hardcopy on this link, which basically says:\n\nhardcopy Ctrl+a h Writes out the current display contents to the file hardcopy.n in the window's default directory, where n is the number of the current window. This either appends or overwrites the file if it exists, as determined by the hardcopy_append command.\nlog Ctrl+a H Begins/ends logging of the current window to the file screenlog.n in the window's default directory, where n is the number of the current window. If no parameter is given, the logging state is toggled. The session log is appended to the previous contents of the file if it already exists. The current contents and the contents of the scrollback history are not included in the session log. Default is off.\n\n\nObserved Behavior\nSo, as far as I understood by this and trying to use them, after enabling screenlog, it keeps logging everything I write and all the outputs of terminal in that file (which happens to go $HOME for me) including those characters to change color like \\033[1;31mm. If I do cat screenlog.0, it crashes sometimes printing the file indefinitely, but ok, I can open it with an editor or in another session...\nAs for hardcopy, apparently it doesn't keep tracking commands, nor colors of outputs, and I don't know if it takes only those few lines that are visible in terminal or everything that happened on that session, could someone clarify this to me?\nFinally, I'm opening screen on Terminator instead of the classical terminal, and even if I open different screen sessions on different windows of Terminator, all logs go to screenlog.0 or hardcopy.0. In the case of screenlog, will it conflict with another process that's being output on other sessions or overwrite it? How can I create different screenlog.n files and put them in a directory other than $HOME?\n\nFurther Considerations\nJust to conclude, which one is recommended?\nSorry for this huge question, but I'm trying to write it in a way that it can be useful to clarify details of these logs that I'm having a hard time to find in other places. Feel free to correct me if I said something wrong :)"

"Difference between Mongoose array and Javascript Array",
"Recently, I got a quite wired question on Mongoose, It's about the using of array. There is different use experience but I cannot find out any discussion or issue on this, so I tried to explain here, and ask someone know what's happened.\n\nIn javascript, Object is added as reference to array\n\n let existed;\n let company = { _id: \"87\" };\n let post = { evaluations: [] };\n let cost = 5;\n let predictDays = 1;\n let content = \"8\";\n if(!existed)\n {\n existed = {};\n existed.company = company._id;\n post.evaluations.push(existed);\n }\n\n existed.cost = cost || 99999999;\n existed.predictDays = predictDays || 100;\n existed.content = content || \"\";\n console.log(existed);\n console.log(post.evaluations);\n\n\nOutput:\n\n{company: \"87\", cost: 5, predictDays: 1, content: \"8\"}\n[{company: \"87\", cost: 5, predictDays: 1, content: \"8\"}]\n\n\nIn nodejs + mongoose, I got the totally different experience.\n\npost is Document from findById.\n\n let existed;\n if(!existed)\n {\n existed = {};\n existed.company = company._id;\n post.evaluations.push(existed);\n /* existed = post.evaluations.find((evaluation) => {\n return evaluation.company.toString() === company._id.toString();\n });*/ // Uncomments this would make existed get the working reference as javascript\n }\n existed.cost = cost || 99999999;\n existed.predictDays = predictDays || 100;\n existed.content = content || \"\";\n console.log(existed);\n console.log(post.evaluations);\n\n\nOutput:\n\n{\n company: 5d655f7743e25137f8501c38,\n cost: 50,\n predictDays: 3,\n content: '123321'\n}\n[{\"company\":\"5d6562bfef7d771e4815dd4f\"}]\n\n\nI cannot figure out why It's not working, but If I uncomment the code, that findagain in array, I could get the expected result as below:\n\n{\n company: 5d655f7743e25137f8501c38,\n cost: 50,\n predictDays: 3,\n content: '123321'\n}\n[{\"company\":\"5d6563391fc9b65250e83988\",\"cost\":50,\"predictDays\":3,\"content\":\"123321\"}]\n\n\nDid mongoose change the push behavior secretly? Hope It's enough infomation to point out my issue, any information is greatly appreciated."
