• Flex 3 - Full unicode support fonts and CSS

  - by BS_C3

  Hi! I'm developping a web application that will be used either in Europe or in Asia (specially Japan -Hiragana, Kanji and Katana-, China and Korea). I'm using the following fonts: - ericssonga628.TTF - HelveticaNeueLTStd-Lt.otf - HelveticaNeueLTStd-LtEx.otf - HelveticaNeueLTStd-Bd.otf - HelveticaNeueLTStd-BdEx.otf When I tried to display Japanese characters, I don't get anything. I guess these fonts don't support East Asian characters... Do you know of any equivalent fonts? Also, I was thinking of creating a CSS for each language (or pack of languages) when the user changes the display language. For example, if the user selects "japanese", I'll use the japanese stylesheet. However, how do I switch from a CSS to another? Thanks in advance for your answers. Regards,

• Which relational databases exist with a public API for a high level language?

  - by Jens Schauder

  We typically interface with a RDBMS through SQL. I.e. we create a sql string and send it to the server through JDBC or ODBC or something similar. Are there any RDBMS that allow direct interfacing with the database engine through some API in Java, C#, C or similar? I would expect an API that allows constructs like this (in some arbitrary pseudo code): Iterator iter = engine.getIndex("myIndex").getReferencesForValue("23"); for (Reference ref: iter){ Row row = engine.getTable("mytable").getRow(ref); } I guess something like this is hidden somewhere in (and available from) open source databases, but I am looking for something that is officially supported as a public API, so one finds at least a note in the release notes, when it changes. In order to make this a question that actually has a 'best' answer: I prefer languages in the order given above and I will prefer mature APIs over prototypes and research work, although these are welcome as well.

• Pitfalls when converting C++/CLI to C++

  - by directedition

  I have a library written in C++/CLI and I want to open it up. I want it to be as cross-platform as possible and be able to write bindings to it for other languages to use (Java, Python, etc, etc). To do this, the library needs to be in plain C++ for maximum flexibility. I figure that the logical structures are already there, I just need to replace the .NET libraries it uses with the standard C++ ones. Is this a misguided notion? What should I watch out for when making this transition?

• Library for Dataflow in C

  - by msutherl

  How can I do dataflow (pipes and filters, stream processing, flow based) in C? And not with UNIX pipes. I recently came across stream.py. Streams are iterables with a pipelining mechanism to enable data-flow programming and easy parallelization. The idea is to take the output of a function that turns an iterable into another iterable and plug that as the input of another such function. While you can already do this using function composition, this package provides an elegant notation for it by overloading the operator. I would like to duplicate a simple version of this kind of functionality in C. I particularly like the overloading of the operator to avoid function composition mess. Wikipedia points to this hint from a Usenet post in 1990. Why C? Because I would like to be able to do this on microcontrollers and in C extensions for other high level languages (Max, Pd*, Python). * (ironic given that Max and Pd were written, in C, specifically for this purpose – I'm looking for something barebones)

• haskell sorting

  - by snorlaks

  Hello, How can it be done in most simply way to write (or maybe there is something embedded in haskell) function which takse as arguments list of tuples (String, Int) and Int x and return top x tuples as list according to x value. I wonder if its possible to write a function which also takes 3 argument which is the name of (or index) of filed in tuple according to which sorting has to be done. What are best solutions to make it quite generic, Im new to haskell I would do somethink like that in imperative languages without any problems but I want to know how to write it in quite good way in haskell, thanks for help

• Automatically taking screenshots of program window

  - by Sergey Kornilov

  I'm looking for a software that combines macro recording with screenshot taking capabilities. We have a software manual with a number of screenshots. When new version of software is released we need to update most of screenshots and we have to do it manually. Now we started translating manual to several languages and number of screenshots to take have increased ten fold. We'd like to automate this process. There will be a recorded macro or something that clicks button within our software and takes screenshots of the program window. Better yet, we can specify the name of each screenshot individually though it's less important. Does such a thing exist?

• Best Online C++ Refresher

  - by Bill

  It's been a longtime since I've done any C++ (probably about 13 years, since I graduated college). I've developing in various others languages since then. My new gig uses a fair bit of C++. Any recommendations for getting bootstrapped? To clarify -- I don't need an "into to programming" book. E.g., what's a variable, flow control, etc. I understand the concepts of OO having implemented them, etc. I'm looking for the best way to get to the specifics of C++.

• Why learn Perl, Python, Ruby if the company is using C++, C# or Java as the application language?

  - by szabgab

  I wonder why would a C++, C#, Java developer want to learn a dynamic language? Assuming the company won't switch its main development language from C++/C#/Java to a dynamic one what use is there for a dynamic language? What helper tasks can be done by the dynamic languages faster or better after only a few days of learning than with the static language that you have been using for several years? Update After seeing the first few responses it is clear that there two issues. My main interest would be something that is justifiable to the employer as an expense. That is, I am looking for justifications for the employer to finance the learning of a dynamic language. Aside from the obvious that the employee will have broader view, the employers are usually looking for some "real" benefit.

• Is it good practice to avoid declaring a pointer to BOOL type in objective C?

  - by Krishnan

  I read this question in stackoverflow. The excerpt answer provided by bbum is below: The problem isn't the assignment, it is much more likely that you declared your instance variable to be BOOL *initialBroadcast;. There is no reason to declare the instance variable to be a pointer (at least not unless you really do need a C array of BOOLs).. Remove the * from the declaration. 1.Is there anything wrong in using a pointer variable even when I do not have to maintain an array of BOOLs? 2.I think even if avoiding them a good practice, it is not specific to objective-C and applies to all programming languages which has pointers. Please answer my questions.

• Why is super.super.method(); not allowed in Java?

  - by Tim Büthe

  I read this question and thought that would easily be solved (not that it isn't solvable without) if one could write: @Override public String toString() { return super.super.toString(); } I'm not sure if it is useful in many cases, but I wonder why it isn't and if something like this exists in other languages. What do you guys think? EDIT: To clarify: yes I know, that's impossible to at to Java and I don't really miss it. This is nothing I expected to work and was surprised getting a compiler error. I just had the idea and like to discuss it.

• Operations inside Rails I18n locales' strings

  - by Cristobal Viedma

  Hi, I am trying to put operations inside the locales to adapt to different languages. For example, in English a billion is 1,000,000,000, however in Spanish a billion is 1,000,000,000,000 so I would like to be able to have the following: en: billion: "You have %{money} billions" es: billion: "Tienes %{money/1000.0} billones" In order to be able to write: I18n.t :billion, :money => whatever And be right for whatever language. However, it seems that I cannot put operations inside the locales' strings. Any hint on how should I be doing this? Maybe my approach is just wrong "philosophically" talking? Thanks all!

• Japanese character stored in SQL Server DB using ASP page that assumed it as ISO-8859-1 encoding

  - by Vishal Seth

  We have a legacy ASP based product that allowed the UI and Data languages of user groups to be configured according to their locations. CodePage and CharSet in ASP pages collecting data was set accordingly. I've noticed few instances in the SQL Server DB where users posted Japanese characters in the ASP page that assumes the oncoming stream to be of ISO-8859-1/Western and as a result, the data in the SQL table has gobbled up. While upgrading the client to our new product, I want to back-convert those "garbage" Japanese (in some instances Chinese) characters back to their actual form. Can I create some utility ASP page that would go through such data values and "fix" the wrongly-encoded strings and store everything back as utf-8 strings? In any case, I don't want to affect my French/Spanish/English characters that might be there as well.

• Using system time directly to get random numbers

  - by Richard Mar.

  I had to return a random element from an array so I came up with this placeholder: return codes[(int) (System.currentTimeMillis() % codes.length - 1)]; Now than I think of it, I'm tempted to use it in real code. The Random() seeder uses system time as seed in most languages anyway, so why not use that time directly? As a bonus, I'm free from the worry of non-random lower bits of many RNGs. It this hack coming back to bite me? (The language is Java if that's relevant.)

• Best and shortest books on C++/STL/C#/J2SE to prepare for job inteview/tests

  - by Nerd

  I am a software developer with 10+ years commercial experience, I am comfortable with nearly all of imperative languages. But I realized that most of employers prefer not candidates who is able to deliver good software but those who is trained to answer questions like "what are ten differences between pointers and references in C++" or "what this messy code fragment will print". Last time I have read a book on C++ 15 years ago in secondary school and yes, that was Bjarne Stroustrup. But today I need something quick, without long philosophical explanations about polymorphism etc but with focus to silly interview tests. So, can you recommend any short and effective books to refresh my theoretical knowledge? Thank you.

• Simple interlinear gloss: aligned bilingual paragraph

  - by D W

  An interlinear gloss can be used to layout a translation of a document. http://en.wikipedia.org/wiki/Interlinear_gloss Usually this is done word-by-word or morpheme-by-morpheme. However, I would like to do this in a different way, translating entire paragraphs at a time. http://www.optimnem.co.uk/learning/spanish/three-little-pigs.php For now I am not interested in taking into account the order of words or phrases that change order between languages. That is, I don't mind if the words in the paragraph are not aligned or if the length of one paragraph is much longer than the other, causing an overhanging line. As far as I can tell, the following packages do not meet my needs: covingtn.sty cgloss4e.sty gb4e.sty lingmacros.sty - shortex

• Capturing system command output as a string

  - by dreeves

  Perl and PHP do this with backticks. For example: $output = `ls`; This code returns a directory listing into the variable $output. A similar function, system("ls"), returns the operating system return code for the given command. I'm talking about a variant that returns whatever the command prints to stdout. (There are better ways to get the list of files in a directory; the example code is an example of this concept.) How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)

• SQL return ORDER BY result as an array

  - by EarthMind

  Is it possible to return groups as an associative array? I'd like to know if a pure SQL solution is possible. Note that I release that I could be making things more complex unnecessarily but this is mainly to give me an idea of the power of SQL. My problem: I have a list of words in the database that should be sorted alphabetically and grouped into separate groups according to the first letter of the word. For example: ape broom coconut banana apple should be returned as array( 'a' => 'ape', 'apple', 'b' => 'banana', 'broom', 'c' => 'coconut' ) so I can easily created sorted lists by first letter (i.e. clicking "A" only shows words starting with a, "B" with b, etc. This should make it easier for me to load everything in one query and make the sorted list JavaScript based, i.e. without having to reload the page (or use AJAX). Side notes: I'm using PostgreSQL but a solution for MySQL would be fine too so I can try to port it to PostgreSQL. Scripting language is PHP.

• Vim syntax/compile-time error highlighting

  - by Tim Nordenfur

  Is there a Vim script that periodically tries to compile/interpret the code that I'm working on, and highlights syntax errors? I'd like it to point out that something is wrong between these lines: int a = 42 cout << a << endl; Such a thing would save me loads of time. I'm primarily searching for a Perl-syntax checker, but I'd also be interested in similar plugins for other languages. Update: Another error I'd like it to point out: int a == 42; cout << a << endl;

• Compiling C-dll for Python OR SWIG-module creation, how to continue ??

  - by ljuju

  I reference this file "kbdext.c" and its headerfile listed on http://www.docdroppers.org/wiki/index.php?title=Writing_Keyloggers (the listings are at the bottom). I've been trying to compile this into a dll for use in Python or Visual Basic, but have not succeeded. I'm not familiar with C or GCC to sort out the problems or do the dll compile correctly. (I also get an error about snprintf not being declared when doing a regular compile of all the files). What are the steps I should do to make all functions available for other languages and external apps? Or is it perhaps easier to use SWIG and make a python module, instead of compiling a DLL?

• C# logic order and compiler behavior

  - by Terrapin

  In C#, (and feel free to answer for other languages), what order does the runtime evaluate a logic statement? Example: DataTable myDt = new DataTable(); if (myDt != null && myDt.Rows.Count > 0) { //do some stuff with myDt } Which statement does the runtime evaluate first - myDt != null or: myDt.Rows.Count > 0 ? Is there a time when the compiler would ever evaluate the statement backwards? Perhaps when an "OR" operator is involved?

• Options for storing large text blobs in/with an SQL database?

  - by kdt

  Hi, I have some large volumes of text (log files) which may be very large (up to gigabytes). They are associated with entities which I'm storing in a database, and I'm trying to figure out whether I should store them within the SQL database, or in external files. It seems like in-database storage may be limited to 4GB for LONGTEXT fields in MySQL, and presumably other DBs have similar limits. Also, storing in the database presumably precludes any kind of seeking when viewing this data -- I'd have to load the full length of the data to render any part of it, right? So it seems like I'm leaning towards storing this data out-of-DB: are my misgivings about storing large blobs in the database valid, and if I'm going to store them out of the database then are there any frameworks/libraries to help with that? (I'm working in python but am interested in technologies in other languages too)

• What's the most effective path to top level development?

  - by Glycerine

  I got a questions asked from one of my delegates the other day, "how did you get to where you are in programming?" I'm now at a java application realm - and I'm just about OK at it. the path that brought me there: BASIC VB6 PHP javascript actionscript java/objective-C I still live in the web development but I now prefer java - I see this as a good flow but I was wondering how you guys got to where you are and the best path to take? Edit: reword I guess I've asked the question wrong - I was wondering how to progress to a top level application from starting off in development. Where good paradyms connect languages. I won't have considered C++ as my first language see.

• What are good alternatives to SQL (the language)?

  - by Brendan Long

  I occasionally hear things about how SQL sucks and it's not a good language, but I never really hear much about alternatives to it. So, are other good languages that serve the same purpose (database access) and what makes them better than SQL? Are there any good databases that use this alternative language? EDIT: I'm familiar with SQL and use it all the time. I don't have a problem with it, I'm just interested in any alternatives that might exist, and why people like them better. I'm also not looking for alternative kinds of databases (the NoSQL movement), just different ways of accessing databases.

• Recommended place for pre-translated Zend Framework resources

  - by Exception e

  Since zf 1.10 Zend Framework ships with pre-translated validation messages. They are outside the library path. The manual illustrates how to load these in your bootstrap. $translator = new Zend_Translate( 'array', '/resources/languages', $language, array('scan' => Zend_Locale::LOCALE_DIRECTORY) ); Zend_Validate_Abstract::setDefaultTranslator($translator); I am inclined to think that these resources are specific to the zf-version; validators could change over time. If i copy the resources to my application tree I need to perform additional maintenance each time I upgrade to a newer version. What is best practice? Is there a ZF convention already?

• Linux program - reverse highlighted text

  - by Oren

  I want to develop a program that will run on the background of my Ubuntu 12.04 so when some text is selected in some textbox of any running program and some key-combination is pressed (like ctrl-F12), the text will be cut, reversed, and pasted in the same place. I know some programs that do it on windows. It is useful in some programs and web-pages that do not support right-to-left languages like arabic and hebrew - the letters are printed from left to right so the text becomes reversed. More specifically I need it in Prezi that has this kind of bug in their embedded flash editor (I thought about writing a chrome-plugin, but I don't think such plugin can manipulate the selected text inside a flash objects). Do you know if such a program exist? Where should I start reading in order to develop a program with such capabilities (manipulate selected text in other programs)? Thanks
