  • Good code highlighting, syntax analysis and code assist editor on js.erb and css.erb files

    - by Pickachu
    I want to know if there is a good compatible api that supports erb and javascript highlighting. I've already tried Eclipse with Aptana RadRails. Perhaps I'm configuring something wrong, but it guesses that I'm using html.erb on both css.erb and js.erb files. I've tried too the Emacs with js2-mode, nXhtml and Rinari modes. Again, it works fine for html.erb, but it detects the css.erb and js.erb as html.erb files. Maybe it's possible to configure it to accept that files and be compatible.

  • Is this a good code (came across while reading code of a colleague)

    - by eriks
    // file a.hpp class a; typedef boost::shared_ptr<a> aPtr class a{ public: static aPtr CreateImp(); virtual void Foo() = 0 ; .... }; //file aImp.hpp class aImp : public a{ virtual void Foo(); }; //file aImp.cpp aPtr a::CreateImp() { return aPtr(new aImp()); } void aImp::Foo(){} The client must use CreateImp to get ptr to 'a', and can't use 'a' other ways. What do you think about this implementation? what do you think about this king of implementation?

  • Large Scale VHDL modularization techniques

    - by oxinabox.ucc.asn.au
    I'm thinking about implimenting a 16 bit CPU in VHDL. A simplish CPU. ADD, MULS, NEG, BitShift, JUMP, Relitive Jump, BREQ, Relitive BREQ, i don't know somethign along these lines Probably all only working with 16bit operands. I might even cut it down and use only a single operand and a accumulator. With Some status regitsters, Carry, Zero, Neg (unless i use a Accumlator), I know how to design all the parts from logic gates, and plan to build them up from first priciples, So for my ALU I'll need to 'build' a ADDer, proably a Carry Look ahead, group adder, this adder it self is make up oa a couple of parts, wich are themselves made up of a couple of parts. Anyway, my problem is not the CPU design, or the VHDL (i know the language, more or less). It's how i should keep things organised. How should I use packages, How should I name my processes and port maps? (i've never seen the benifit of naming the port maps, or processes)

  • ASP .NET Code analysis tool to check cross site scripting

    - by Prashant
    I am aware of a tool which MS has provided which tells you about coss site scripting attack etc. The tool is http://www.microsoft.com/downloads/details.aspx?FamilyId=0178e2ef-9da8-445e-9348-c93f24cc9f9d&displaylang=en But are there tools which you have used for ASP .NET applications which do similar to this and which one is widely used in ASP .Net applications ?

  • Example code of libssh2 being used for port forwarding

    - by flxkid
    I'm looking for an example of how to use libssh2 to setup ssh port forwarding. I've looked at the API, but there is very little in the way of documentation in the area of port forwarding. For instance, using PuTTY plink, There is the remote port to listen on, but also the local port that traffic should be sent to. Is it the developers responsibility to do this part? Can an example be developed of this? Also, for the opposite, where a remote port is brought to a local port, do I use libssh2_channel_direct_tcpip_ex? What about an example of this? I really need to do this exact thing on a project right now. How hard would it be to develop a couple of samples of this? I'm willing to put up a bounty if need be to get a couple of working examples of this.

  • Project summary - Source code lines

    - by MartyIX
    I'm looking for a tool that would count the number of files, the number of lines (with or without comments) and possibly other statistics for my project in PHP and JavaScript. Notes: I've already found SLOCCount which seems quite nice. It requires Cygwin. Yes, I can wrote a simple script for basic information but I'm looking for something more complex. Do you know about alternatives for Windows? Thanks!

  • Converter problem with XmlDataProvider

    Sorry for this, I've just started programming with wpf. I can't seem to figure out why the following xaml displays "System.Xml.XmlElement" instead of the actual xml node content.

  • Code golf: Word frequency chart

    - by ChristopheD
    The challenge: Build an ASCII chart of the most commonly used words in a given text. The rules: Only accept a-z and A-Z (alphabetic characters) as part of a word. Ignore casing (She == she for our purpose). Ignore the following words (quite arbitary, I know): the, and, of, to, a, i, it, in, or, is Clarification: considering don't: this would be taken as 2 different 'words' in the ranges a-z and A-Z: (don and t). Optionally (it's too late to be formally changing the specifications now) you may choose to drop all single-letter 'words' (this could potentially make for a shortening of the ignore list too). Parse a given text (read a file specified via command line arguments or piped in; presume us-ascii) and build us a word frequency chart with the following characteristics: Display the chart (also see the example below) for the 22 most common words (ordered by descending frequency). The bar width represents the number of occurences (frequency) of the word (proportionally). Append one space and print the word. Make sure these bars (plus space-word-space) always fit: bar + [space] + word + [space] should be always <= 80 characters (make sure you account for possible differing bar and word lenghts: e.g.: the second most common word could be a lot longer then the first while not differing so much in frequency). Maximize bar width within these constraints and scale the bars appropriately (according to the frequencies they represent). An example: The text for the example can be found here (Alice's Adventures in Wonderland, by Lewis Carroll). This specific text would yield the following chart: _________________________________________________________________________ |_________________________________________________________________________| she |_______________________________________________________________| you |____________________________________________________________| said |____________________________________________________| alice |______________________________________________| was |__________________________________________| that |___________________________________| as |_______________________________| her |____________________________| with |____________________________| at |___________________________| s |___________________________| t |_________________________| on |_________________________| all |______________________| this |______________________| for |______________________| had |_____________________| but |____________________| be |____________________| not |___________________| they |__________________| so For your information: these are the frequencies the above chart is built upon: [('she', 553), ('you', 481), ('said', 462), ('alice', 403), ('was', 358), ('that ', 330), ('as', 274), ('her', 248), ('with', 227), ('at', 227), ('s', 219), ('t' , 218), ('on', 204), ('all', 200), ('this', 181), ('for', 179), ('had', 178), (' but', 175), ('be', 167), ('not', 166), ('they', 155), ('so', 152)] A second example (to check if you implemented the complete spec): Replace every occurence of you in the linked Alice in Wonderland file with superlongstringstring: ________________________________________________________________ |________________________________________________________________| she |_______________________________________________________| superlongstringstring |_____________________________________________________| said |______________________________________________| alice |________________________________________| was |_____________________________________| that |______________________________| as |___________________________| her |_________________________| with |_________________________| at |________________________| s |________________________| t |______________________| on |_____________________| all |___________________| this |___________________| for |___________________| had |__________________| but |_________________| be |_________________| not |________________| they |________________| so The winner: Shortest solution (by character count, per language). Have fun! Edit: Table summarizing the results so far (2012-02-15) (originally added by user Nas Banov): Language Relaxed Strict ========= ======= ====== GolfScript 130 143 Perl 185 Windows PowerShell 148 199 Mathematica 199 Ruby 185 205 Unix Toolchain 194 228 Python 183 243 Clojure 282 Scala 311 Haskell 333 Awk 336 R 298 Javascript 304 354 Groovy 321 Matlab 404 C# 422 Smalltalk 386 PHP 450 F# 452 TSQL 483 507 The numbers represent the length of the shortest solution in a specific language. "Strict" refers to a solution that implements the spec completely (draws |____| bars, closes the first bar on top with a ____ line, accounts for the possibility of long words with high frequency etc). "Relaxed" means some liberties were taken to shorten to solution. Only solutions shorter then 500 characters are included. The list of languages is sorted by the length of the 'strict' solution. 'Unix Toolchain' is used to signify various solutions that use traditional *nix shell plus a mix of tools (like grep, tr, sort, uniq, head, perl, awk).

  • SEO redirects for removed pages

    - by adam
    Hi, Apologies if SO is not the right place for this, but there are 700+ other SEO questions on here. I'm a senior developer for a travel site with 12k+ pages. We completely redeveloped the site and relaunched in January, and with the volatile nature of travel, there are many pages which are no longer on the site. Examples: /destinations/africa/senegal.aspx /destinations/africa/features.aspx Of course, we have a 404 page in place (and it's a hard 404 page rather than a 30x redirect to a 404). Our SEO advisor has asked us to 30x redirect all our 404 pages (as found in Webmaster Tools), his argument being that 404's are damaging to our pagerank. He'd want us to redirect our Senegal and features pages above to the Africa page (which doesn't contain the content previously found on Senegal.aspx or features.aspx). An equivalent for SO would be taking a url for a removed question and redirecting it to /questions rather than showing a 404 'Question/Page not found'. My argument is that, as these pages are no longer on the site, 404 is the correct status to return. I'd also argue that redirecting these to less relevant pages could damage our SEO (due to duplicate content perhaps)? It's also very time consuming redirecting all 404's when our site takes some content from our in-house system, which adds/removes content at will. Thanks for any advice, Adam

  • Is there a way to do simple calculations in a xaml element binding statement other than using a conv

    - by Jonathan Websdale
    In XAML I want to bind the height of one element to be half the height of another element. Is there a way to do this that doesn't involve writing a converter in the code-behind? Example:- What I've got... <Button Name="RemoveButton" Content="Remove Stage" Width="100" Height="{Binding ElementName=AddButton, Path=Height, Converter={StaticResource MyHalfHeightConverter}}"/> What I'd like... <Button Name="RemoveButton" Content="Remove Stage" Width="100" Height="{Binding ElementName=AddButton, Path=(Height / 2.0)}"/>

  • What HTTP redirect status should I use to link offsite?

    - by Matthew Scharley
    While randomly browsing my website via Google, I noticed that it was showing up remote redirects as local files. Now this can be both good and bad, but I'm wondering how can I fix this so it doesn't happen? I'm currently using PHP and header('Location: ... which sends a 302 redirect. Looking over the list of HTTP status codes, I'd take a guess that I should be using 303 redirects to redirect offsite. Is anyone able to help me here, and either confirm/deny this, or tell me what I should be doing instead? Obviously, due to me not being able to tell Google to reindex my site on command, there's issues with being able to test this myself...
