• Including a pyd directly in a setup.py file

  - by Philippe Beaudoin

  I have a complex build process to generate a couple of python extension modules (.pyd). I want to include these in my setup.py for use with distutils. The distutils page talks in length about how to add extension modules from source, but I'd want to simply package these precompiled .pyd. What is the best practice to do this? Eventually, I'd also like to freeze everything in an executable with py2exe. Will I be able to do this if I directly specify the .pyd?

• MVVM - RaisePropertyChanged turning code into a mess

  - by vidalsasoon

  New to MVVM so please excuse my ignorance. I THINK i'm using it right but I find my ViewModel has too many of these: RaisePropertyChanged("SomeProperty") Every time I set a property I have to raise that damned property changed. I miss the days where I could just go: public int SomeInteger { get; private set;} These days I have to stick the "RaisePropertyChanged" in everywhere or my UI does not reflect the changes :( Am I doing it wrong or are other people getting annoyed with the excessive number of magic strings and old school property setters? Should I be using dependency properties instead? (I doubt that would help the code bloat anyway) Despite these problems I still think MVVM is the way to go so I guess that's something.

• Can a CouchDB document update handler get an update conflict?

  - by jhs

  How likely is a revision conflict when using an update handler? Should I concern myself with conflict-handling code when writing a robust update function? As described in Document Update Handlers, CouchDB 0.10 and later allows on-demand server-side document modification. Update handlers can process non-JSON formats; but the other major features are these: An HTTP front-end to arbitrarily complex document modification code Similar code needn't be written for all possible clients—a DRY architecture Execution is faster and less likely to hit a revision conflict I am unclear about the third point. Executing locally, the update handler will run much faster and with lower latency. But in situations with high contention, that does not guarantee a successful update. Or does the update handler guarantee a successful update?

• Higher than high-level web frameworks or CMS's?

  - by Ben

  I'm looking for options that allow very high-level web site development with these special characteristics: not requiring the user to program in a complex programming language not requiring the user to use GUI-like administration areas allow the user to "program" in a lightweight markup language The last point is not only about look and structure of the output but also about creating simple dynamic output. For example: listing pages fetching the content of other pages doing a site search and displaying its output dynamically show or hide parts of the page depending on login status Of course, I am not expecting a solution that provides the same possibilities like a Ruby, Python or PHP web framework. Rather I am looking for support of the "basics" that are common for web sites. Until now, I have found only one piece of software that fulfills these requirements but while it's free, it's not open source: BoltWire at http://www.boltwire.com/. Being open source is required.

• Want to load jquery dialog from a different web-page

  - by Jake

  I'm a bit of a n00b with jquery so this one is probably an RTFM question: I'm writing an application to create a somewhat complex record for my client. Building the record requires doing a couple of server side searches inside a dialog. Right now I have everything framed up in 1 file (asp.net) and it's ok. But I can see as I add the business logic and the communication with the server this is going to get really ugly. I'm alreay putting most of the javascript in external files, but I'd like to move the HTML for the dialogs out too. How do I get the jquery dialog method to load the dialog body from the html files? Something like: getDialogHTML(dialogHolderDiv); <---magic goes here var dialogOptions = { ... }; $("#"+dialogHolderDiv).dialog(dialogOptions); $("#"+dialogHolderDiv).dialog('open'); any help will be apperciated .

• Graph databases and Php

  - by stagas

  I want to use a graph database using php. Can you point out some resources on where to get started? Is there any example code / tutorial out there? Or are there any other methods of storing data that relate to each other in totally random/abstract situations? Very abstract example of the relations needed: John relates to Mary, both relate to School, John is Tall, Mary is Short, John has Blue Eyes, Mary has Green Eyes, query I want is which people are related to 'Short people that have Green Eyes and go to School' - answer John It is possible in MySQL but it would require a fixed set of attributes/columns for each item and a complex non-flexible query, instead I need every attribute to be an item by itself and instead of 'belonging' to something, to be 'related' to something.

• RegEx for MetaMap in Java

  - by Christian

  MetaMap files have following lines: mappings([map(-1000,[ev(-1000,'C0018017','Objective','Goals',[objective],[inpr],[[[1,1],[1,1],0]],yes,no)])]). The format is explained as mappings( [map(negated overall score for this mapping, [ev(negated candidate score,'UMLS concept ID','UMLS concept','preferred name for concept - may or may not be different', [matched word or words lowercased that this candidate matches in the phrase - comma separated list], [semantic type(s) - comma separated list], [match map list - see below],candidate involved with head of phrase - yes or no, is this an overmatch - yes or no ) ] ) ] ). I want to run a RegEx query in java that gives me the Strings 'UMLS concept ID', semantic type and match map list. Is RegEx the right tool or what is the most efficent way to accomplish this in Java?

• how to profile silverlight mvvm application with a lot of custom controls

  - by tomo

  There is a quite big LOB silverlight application and we wrote a lot of custom controls which are rather heavy in drawing. All data is loaded by RIA service, processed and bound (using INofityPropertyChanged interface) to the view. The problem is that first drawing takes a lot time. Following calls to the service (server) and redrawing is quite fast. I used Equatec profiler to track the problem. I saw that processing takes a couple of miliseconds only so my idea is that the drawing by SL engine is slow. I'm wondering if it is possible to profile somehow processes inside SL to check which drawing operations are taking too much time. Are there any guidelines how to implement faster drawing of complex custom controls?

• Prevent python from printing newline

  - by wrongusername

  I have this code in Python inputted = input("Enter in something: ") print("Input is {0}, including the return".format(inputted)) that outputs Enter in something: something Input is something , including the newline I am not sure what is happening; if I use variables that don't depend on user input, I do not get the newline after formatting with the variable. I suspect Python might be taking in the newline as input when I hit return. How can I make it so that the input does not include any newlines so that I may compare it to other strings/characters? (e.g. something == 'a')

• Splitting a string according to a delimiter when elements in the string can contain the delimiter

  - by Vivin Paliath

  I have a string that looks like this: "#Text() #SomeMoreText() #TextThatContainsDelimiter(#blah) #SomethingElse()" I'd like to get back [#Text(), #SomeMoreText(), #TextThatContainsDelimiter(#blah), #SomethingElse()] One way I thought about doing this was to require that the # to be escaped into \#, which makes the input string: "#Text() #SomeMoreText() #TextThatContainsDelimiter(\#blah) #SomethingElse()" I can then split it using /[^\\]#/ which gives me: [#Text(), SomeMoreText, TextThatContainsDelimiter(\#blah), SomethingElse()] The first element will contain # but I can strip it out. However, is there a cleaner way to do this without having to escape the #, and which ensures that the first element will not contain a #? Basically I'd like it to split by # only if the # is not enclosed by parentheses. My hunch is that since the # is context-sensitive and and regular expressions are only suited for context-free strings, this may not be the right tool. If so, would I have to write a grammar for this and roll my own parser/lexer?

• Find and replace string in MySQL using data from another table

  - by Charlie

  Hi, sorry for formatting this wonky but hope you can understand it. I have two MySql tables, and I want to find and replace text strings in one using data in another. Texts - one column: messages 'thx guys' 'i think u r great' 'thx again' ' u rock' Dictionary - two columns: bad_spelling, good_spelling 'thx' 'thanks' ' u ' ' you ' ' r ' ' are ' I want SQL to go through and look at every row in messages and replace every instance of bad_spelling with good_spelling, and to do this for all the pairs of bad_spelling and good_spelling The closest I have gotten is this: update texts, dictionary set texts.message = replace(texts.message, dictionary.bad_spelling, dictionary.good_spelling) But this only changes 'thx' to 'thanks' (in 2 rows) and does not go on to replace ' u ' with ' you' or ' r ' with ' are '. Any ideas how to make it use all the rows in dictionary in the replace statement? -- PS forgot to mention that this is a small example and in the real thing I will have a lot of find/replace pairs, which may get added to over time.

• TreeMap not properly returning values

  - by smessing

  I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else every encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

• Antlr Lexer Quoted String Predicate

  - by Loki

  I'm trying to build a lexer to tokenize lone words and quoted strings. I got the following: STRING: QUOTE (options {greedy=false;} : . )* QUOTE ; WS : SPACE+ { $channel = HIDDEN; } ; WORD : ~(QUOTE|SPACE)+ ; For the corner cases, it needs to parse: "string" word1" word2 As three tokens: "string" as STRING and word1" and word2 as WORD. Basically, if there is a last quote, it needs to be part of the WORD were it is. If the quote is surrounded by white spaces, it should be a WORD. I tried this rule for WORD, without success: WORD: ~(QUOTE|SPACE)+ | (~(QUOTE|SPACE)* QUOTE ~QUOTE*)=> ~(QUOTE|SPACE)* QUOTE ~(QUOTE|SPACE)* ;

• How to customize pickle for django model objects

  - by muudscope

  I need to pickle a complex object that refers to django model objects. The standard pickling process stores a denormalized object in the pickle. So if the object changes on the database between pickling and unpickling, the model is now out of date. (I know this is true with in-memory objects too, but the pickling is a convenient time to address it.) So what I'd like is a way to not pickle the full django model object. Instead just store its class and id, and re-fetch the contents from the database on load. Can I specify a custom pickle method for this class? I'm happy to write a wrapper class around the django model to handle the lazy fetching from db, if there's a way to do the pickling.

• mod_rewrite and pretty urls

• Determining whether values can potentially match a regular expression, given more input

  - by Andreas Grech

  I am currently writing an application in JavaScript where I'm matching input to regular expressions, but I also need to find a way how to match strings to parts of the regular expressions. For example: var invalid = "x", potentially = "g", valid = "ggg", gReg = /^ggg$/; gReg.test(invalid); //returns false (correct) gReg.test(valid); //returns true (correct) Now I need to find a way to somehow determine that the value of the potentially variable doesn't exactly match the /^ggg$/ expression, BUT with more input, it potentially can! So for example in this case, the potentially variable is g, but if two more g's are appended to it, it will match the regular expression /^ggg$/ But in the case of invalid, it can never match the /^ggg$/ expression, no matter how many characters you append to it. So how can I determine if a string has or doesn't have potential to match a particular regular expression?

• Compare two String with MySQL

  - by Scorpi0

  Hi, I wan't to compare two strings in a SQL request so I can retrieve the best match, the aim is to propose to an operator the best zip code possible. For example, in France, we have Integer Zip code, so I made an easy request : SELECT * FROM myTable ORDER BY abs(zip_code - 75000) This request returns first the data closest of Paris. Unfortunatelly, United Kingdom have zip code like AB421RS, so my request can't do it. I see in SQL Server a function 'Difference' : http://www.java2s.com/Code/SQLServer/String-Functions/DIFFERENCEworkoutwhenonestringsoundssimilartoanotherstring.htm But I use MySQL.. Is there anyone who have a good idea to do the trick in one simple request ? PS : the Levenshtein Distance will not do it, as I really wan't to compare string like if they were number. ABCDEF have to be closer to AWXYZ than to ZBCDEF.

• Multilangual Unicode rendering in opengl

  - by sum1stolemyname

  Hi Folks, I have to extend an OpenGL-Rendering System to support international characters (especially Hebrew, Arabic and cyrillic). Development Platform is Windows(XP|Vista|7), Alas using Embercardero Delphi 2010. I currently use wglOutLineFont(...) to build my font's display list and glCallLists(length(m_Text), UNSIGNED_SHORT, PWchar(m_Text) ) to render my strings. While this is feasable for Latin-1 Characters, building the full unicode character set in advanced is pretty time-consuming (about 8.5 minutes on my machine), so i am looking for a more efficient solution. I thought about limiting the range from u+0020 - u+077f (latin, greek, cyrillic, arbaic and hebrew) to include just the glyphs i need, but that would just be a solution for my current needs, and will become insufficent once other encoding is needed. On the upside, i do not have to worry about left-to right or right-to left direction as our application can handle this already. I would expect this to be a well-known problem, so i would like to ask if there is any reference material on this on the web, or if you could share some insight on this?

• Optimizing if-else /switch-case with string options

  - by cc

  What modification would bring to this piece of code? In the last lines, should I use more if-else structures, instead of "if-if-if" if (action.equals("opt1")) { //something } else { if (action.equals("opt2")) { //something } else { if ((action.equals("opt3")) || (action.equals("opt4"))) { //something } if (action.equals("opt5")) { //something } if (action.equals("opt6")) { //something } } } Later Edit: This is Java. I don't think that switch-case structure will work with Strings. Later Edit 2: A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ).

• Why is there an implicit conversion from Float/Double to BigDecimal, but not from String?

  - by soc

  Although the situation of conversion from Doubles to BigDecimals has improved a bit compared to Java scala> new java.math.BigDecimal(0.2) res0: java.math.BigDecimal = 0.20000000000000001110223024625156... scala> BigDecimal(0.2) res1: scala.math.BigDecimal = 0.2 and things like val numbers: List[BigDecimal] = List(1.2, 3.2, 0.7, 0.8, 1.1) work really well, wouldn't it be reasonable to have an implicit conversion like implicit def String2BigDecimal(s: String) = BigDecimal(s) available by default which can convert Strings to BigDecimals like this? val numbers: List[BigDecimal] = List("1.2", "3.2", "0.7", "0.8", "1.1") Or am I missing something and Scala resolved all "problems" of Java with using the BigDecimal constructor with a floating point value instead of a String, and BigDecimal(String) is basically not needed anymore in Scala?

• Generic structure for performing string conversion when data binding.

  - by Rohan West

  Hi there, a little while ago i was reading an article about a series of class that were created that handled the conversion of strings into a generic type. Below is a mock class structure. Basically if you set the StringValue it will perform some conversion into type T public class MyClass<T> { public string StringValue {get;set;} public T Value {get;set;} } I cannot remember the article that i was reading, or the name of the class i was reading about. Is this already implemented in the framework? Or shall i create my own?

• JavaScript replace with callback - performance question

  - by Tomalak

  In JavaScript, you can define a callback handler in regex string replace operations: str.replace(/str[123]|etc/, replaceCallback); Imagine you have a lookup object of strings and replacements. var lookup = {"str1": "repl1", "str2": "repl2", "str3": "repl3", "etc": "etc" }; and this callback function: var replaceCallback = function(match) { if (lookup[match]) return lookup[match]; else return match; } How would you assess the performance of the above callback? Are there solid ways to improve it? Would if (match in lookup) //.... or even return lookup[match] | match; lead to opportunities for the JS compiler to optimize, or is it all the same thing?
