  • In MySQL how can I tell what character set a particular table is using?

    - by muudscope
    I have a large mysql table that I think might be using the wrong character set. If so I'll need to change it using ALTER TABLE mytable CONVERT TO CHARACTER SET utf8 But since this is a very large table, I'd rather not run this command unless I have to. So my question is, how can I ask mysql what the character set is on a particular table? I can call status in mysql to see the database's character set, but that doesn't necessarily mean all the tables have the same character set, right?

  • Can I use a genetic algorithm for balancing character builds?

    - by Renan Malke Stigliani
    I'm starting to build a online PVP (duel like, one-on-one) game, where there is leveling, skill points, special attacks and all the common stuff. Since I have never done anything like this, I'm still thinking about the math behind the levels/skills/specials balance. So I thought a good way of testing the best builds/combos, would be to implement a Genetic Algorithm. It'd be like this: Generate a big group of random characters Make them fight, level them up accordingly to their victories(more XP)/losses(less XP) Mate the winners, crossing their builds, to try and make even better characters Add some more random chars, emulating new players Repeat the process for some time, or util I find some chars who can beat everyone's butt I could then play with the math and try to find better balances to make sure that the top x% of chars would be a mix of various build types. So, is it a good idea, or is there some other, easier method to do the balancing?

  • Good tutorial resources for creating 2D character sprite?

    - by Rexroth
    I am planning on learning how to create 2D character sprite by myself and making a game using RPG Maker VX Ace. I've been searching for the tutorial of making approx. 32x64 size human character sprite but haven't been able to find one close enough. Most tutorials I've found are either really general or creating sprites that are way too complicated. FYI I wish to learn how to make this type of characters by myself: not too complicated, fit for a small fan-made game made by RPG Maker. Ideally, I wish to learn from the stage of character sketch until realizing the character using photoshop or other kinds of tools (I have some foundations of visual art, it's just that I am not sure how to sketch a character this small). If you know of such tutorial resource please let me know -- thank you very much!

  • Process ANSI escape codes before piping

    - by Tiddo
    I'm trying to pipe the output of a script (Mocha) to another script. However there is one problem: Mocha generates quite a few ansi escape characters to update the screen on the fly. These characters are also send through the pipe. Is there a way to process the ansi sequence such that the output is the same as the final output to the screen? I do want to keep color escape sequences, but not the curser movement escapes. Edit: I have a partial solution now (for Mocha only): so far it seems that Mocha with the spec output (the one I use) only generates color ecape characters and the CSI 0G escape sequence. The CSI 0G escape character means that the cursor should move back to the beginning of the line. Mocha uses this to overwrite a line completely. Therefore you could simply create a sed regexp which will delete everything up to that escape sequence on a line: sed 's/^.*\x1b\[0G//g'. I am still looking for the complete solution though.

  • how to remap Ctrl to Escape if pressed and released on its own

    - by psvm
    I want to remap Control, so that: A. If it is pressed and released with no other key, it acts as Escape. B. If it is pressed & held together with another key, it acts as Control (no change in behavior in this case). I'm aware of How do I remap certain keys?, so I suspect it may be done with xmodmap. But that answer does not explain how to map the modifier keys. I looked into the examples and grammar sections of the xmodmap manpage, but they do not explain that. The answer in Remapping Caps Lock to Control and Escape (not the usual way) mention that it is not possible to do that to CapsLock, since it is a Lock key, but I hope this may be possible to do it with Control which is a mod key. A solution with something different than xmodmap will also be accepted. (I'm running Xmonad in Ubuntu 12.04, so perhaps there is a way to set this up in xmonad.hs?)

  • SQLite character encoding for Google Gears

    - by MHD
    We're using jQuery to get a JSON-string from our server (UTF-8 response, also UTF-8 request through jQuery) and put this JSON into a Google Gears WorkerPool. This workerpool processes the JSON and stores it into a Gears database (SQLite). It turns out that, apparently, SQLite stores data using iso-8859-1 rather than UTF-8. Since we're trying to store user names that might contain Cyrillic characters (and others that you might encounter in Europe), this goes horribly wrong. Can anyone tell me how to change the character encoding in either the Gears WorkerPool or the SQLite database that Gears employs? Of course, if I'm looking in the wrong direction with my problem, feel free to offer alternatives! Unfortunately, HTML5 isn't an option as we're supposed to support IE7 primarily.

  • Passing string with (accidental) escape character loses character even though it's a raw string

    - by Steen
    I have a function with a python doctest that fails because one of the test input strings has a backslash that's treated like an escape character even though I've encoded the string as a raw string. My doctest looks like this: >>> infile = [ "Todo: fix me", "/** todo: fix", "* me", "*/", r"""//\todo stuff to fix""", "TODO fix me too", "toDo bug 4663" ] >>> find_todos( infile ) ['fix me', 'fix', 'stuff to fix', 'fix me too', 'bug 4663'] And the function, which is intended to extract the todo texts from a single line following some variation over a todo specification, looks like this: todos = list() for line in infile: print line if todo_match_obj.search( line ): todos.append( todo_match_obj.search( line ).group( 'todo' ) ) And the regular expression called todo_match_obj is: r"""(?:/{0,2}\**\s?todo):?\s*(?P<todo>.+)""" A quick conversation with my ipython shell gives me: In [35]: print "//\todo" // odo In [36]: print r"""//\todo""" //\todo And, just in case the doctest implementation uses stdout (I haven't checked, sorry): In [37]: sys.stdout.write( r"""//\todo""" ) //\todo My regex-foo is not high by any standards, and I realize that I could be missing something here. EDIT: Following Alex Martellis answer, I would like suggestions on what regular expression would actually match the blasted r"""//\todo fix me""". I know that I did not originally ask for someone to do my homework, and I will accept Alex's answer as it really did answer my question (or confirm my fears). But I promise to upvote any good solutions to my problem here :) I'm using Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) Thank you for reading this far (If you skipped directly down here, I understand)

  • .aspx character coding

    - by kwek-kwek
    I am having an problem. First time working with a windows server, do you know if there is any problem in character coding? My document is set to content="text/html; charset=UTF-8" but it's giving me funny words... you can check it here. This site is a pure HTML with few includes but anything else is just HTML. I can convert them to HTML entities but that is basically wasting my time. I never had this problem with any website I did except for this. Some others said "The problems seems to be that you have converted the text into utf-8 twice.". But how would Coverted it twice since dreamweaver should convert it for me but in this case it doesn't.

  • WinForm Text Control that displays current character/character limit

    - by Refracted Paladin
    I need a way to display, like you see in some web apps, the current characters/character limit for a Text Control(i.e. 3/500). I usually see this as a label residing directly above or below the Text Control. How is this 'normally' accomplished? Should I override my Text Control somehow? Do I just manually add labels by every Text Control and 'bind' them to properties of the Text Control? Do I need to create a composite control that has the Text Control & Label Controls together to accomplish what I need? Any direction or help will be greatly appreciated.

  • C#/Oracle: Specify Encoding/Character Set of Query?

    I'm trying to fetch some Data of a Oracle 10 Database. Some cells are containing german umlauts (äöü). In my Administration-Tool (TOAD) I can see them very well: "Mantel für Damen" (Jacket for Women) This is my C# Code (simplified): var oracleCommand = new OracleCommand(sqlGetArticles, databaseConnection); var articleResult = oracleCommand.ExecuteReader(); string temp = articleResult.Read()["SomeField"].ToString(); Console.WriteLine(temp); The output is: "Mantel f?r Damen" Tryed on Debugging (moving mouse over variable), Debug-Window, Console-Window, File. I think I have to specify the Encoding/Character Set somwhere. But where?

  • JS / JQuery character problem

    - by Jimmy Farax
    I have a code which has a character that JS is not handling properly. $(document).ready(function(){ $.getJSON("http://sjama.tumblr.com/api/read/json?callback=?", function (data){ for (var i=0; i<data.posts.length; i++){ var blog = data.posts[i]; var id = blog.id; var type = blog.type; var photo = blog.photo-url-250; if (type == "photo"){ $("#blog_holder").append('<div class="blog_item_holder"><div class="blog_item_top"><img src='+photo+'/></div><div class="blog_item_bottom">caption will go here</div></div>'); } } }); <!-- end $.getJSON }); The problem is with this line: var photo = blog.photo-url-250; after "blog." it reads the "url" part weirdly because of the dash (-) in between. What can I do to sort this problem out?

  • Character encoding problem in my website.

    - by vikyboss
    I own a website that was recently moved to a different server, now I can see some weird characters. Initially the website was coded with UTF-8 encoding. The weird characters disappears if I change the View Character encoding to Western(8859-1) in my browser. Therefore, I changed the source of the website to use this Western one, but still I can see the weird characters and they doesn't seem to disappear. Can anyone help me with this. Thanks in advance.

  • SQL SERVER – Find First Non-Numeric Character from String

    - by pinaldave
    It is fun when you have to deal with simple problems and there are no out of the box solution. I am sure there are many cases when we needed the first non-numeric character from the string but there is no function available to identify that right away. Here is the quick script I wrote down using PATINDEX. The function PATINDEX exists for quite a long time in SQL Server but I hardly see it being used. Well, at least I use it and I am comfortable using it. Here is a simple script which I use when I have to identify first non-numeric character. -- How to find first non numberic character USE tempdb GO CREATE TABLE MyTable (ID INT, Col1 VARCHAR(100)) GO INSERT INTO MyTable (ID, Col1) SELECT 1, '1one' UNION ALL SELECT 2, '11eleven' UNION ALL SELECT 3, '2two' UNION ALL SELECT 4, '22twentytwo' UNION ALL SELECT 5, '111oneeleven' GO -- Use of PATINDEX SELECT PATINDEX('%[^0-9]%',Col1) 'Position of NonNumeric Character', SUBSTRING(Col1,PATINDEX('%[^0-9]%',Col1),1) 'NonNumeric Character', Col1 'Original Character' FROM MyTable GO DROP TABLE MyTable GO Here is the resultset: Where do I use in the real world – well there are lots of examples. In one of the future blog posts I will cover that as well. Meanwhile, do you have any better way to achieve the same. Do share it here. I will write a follow up blog post with due credit to you.

  • Non-English Character Display in Oracle SQL Developer

    - by thatjeffsmith
    I get a variation on this question at least once a week, if not more frequently. I’m from Israel, and the language on the databases is Hebrew. When I use the old and deprecated SQL*Plus (windows rich client) I can see the hebrew clearly, when I use the latest SQL Developer, I get gibberish. This question appears on the forums about every week or so as well. So what’s the deal? Well, it starts with a basic misunderstanding of NLS Client parameters. These should accurately reflect the language and locality setup on your LOCAL machine. DO NOT COPY what’s set in the database. The these parameters work together with the database so that information can be transferred back and forth correctly. Having the wrong NLS parameters locally can be bad. [ORACLE DOCS]Setting the NLS_LANG parameter properly is essential to proper data conversion. The character set that is specified by the NLS_LANG parameter should reflect the setting for the client operating system. Setting NLS_LANG correctly enables proper conversion from the client operating system character encoding to the database character set. When these settings are the same, Oracle Database assumes that the data being sent or received is encoded in the same character set as the database character set, so character set validation or conversion may not be performed. This can lead to corrupt data if conversions are necessary. OK, so what are you supposed to do? Set the Font! 9 times out of 10, this preference fixes the problem with display issues. Make sure you set a Font that supports the characters you’re trying to display. It’s as simple as that. This preference defines the font used to display characters in the editors and the data grids. If you have it set to a font that doesn’t have Hebrew character support – you’re not going to see Hebrew in SQL Developer. A few years ago…wow, like 15 years ago, I learned that the Tohama Font is pretty Unicode-friendly. Bad Font Selection A Font that’s not non-English friendly Good Font Selection Exact same text, except rendered with the Tahoma font Summary Having problems seeing non-English text in SQL Developer? Check the font! And do not start messing with NLS parameters without talking to your DBA first.

  • Cannot escape character '@' in fstab file

    - by ubuntico
    I want to attach remote FTP directory as a local directory in my system. I will use curlftpfs line in the fstab file , but to login I have to pass my user name and password. The user name has a special character (@) and it needs to be escaped via octal ascii code. The octal ascii for '@' is 100. But when I try to enter the following into the FSTAB file, curlftpfs#myself\100myself.com:ftpPassword@ftp://ftp.mysite.com /mnt/somedir I get an error saying Error connecting to ftp: Couldn't resolve host 'myself.com:ftpPassword@ftp://ftp.mysite.com' The fstab does not recognize escaped symbol @ (\100) and thinks that the FTP site should start immediately after the @ symbol (just like I haven't escaped it). Can someone help? Why I cannot escape @, when it can be done for space character, for example?
