  • parsec-3.1.0 with custom token datatype

    - by Tener
    parsec-3.1.0 ( http://hackage.haskell.org/package/parsec-3.1.0 ) works with any token type. However there are combinators like Text.Parsec.Char.satisfy that are only defined for Char datatype. There doesn't seem to be any more general counterpart available. Should I define my own versions or did I miss something? Perhaps there are different parser libraries in Haskell that allows: custom token types custom parser state (I need to parse stateful format - Wavefront OBJ)

  • C# Putting the required DLLs somewhere other than the root of the output

    - by aip.cd.aish
    I am using EmguCV for a project and when our program runs it needs some dlls like "cxcore.dll" etc. (or it throws runtime exceptions). At the moment, I put the files in the root of the output folder (selected "Copy Always" in the file's properties in Visual Studio). However it looks a bit messy, to have about 10 different dlls just there. Is there someway where I can move it to a subfolder in the output folder and it'll still find it.

  • Way to view Rails Migration output

    - by Ganesh Shankar
    Is there an easy way to see the actual SQL generated by a rails migration? I have a situation where a migration to change a column type worked on my local development machine by partially failed on the production server. My postgreSQL versions are different between local and production (7 on production, 8 on local) so I'm hoping by looking at the SQL generated on the successful migration locally I can work out a SQL statement to run on production to fix things....

  • COM OCX registration - 2 DLL's with same name

    - by Tony
    Hi, I have a native app that has an .OCX file that needs to be registered for it to be used in a .NET application. Now currently there's different versions of this .OCX on the machine. Can someone please explain how this can affect the registration of this new (updated) .OCX file registration? And how does my .NET app know which object to create from which .OCX file?

  • New line in GridView cell

    - by Chris
    I'm binding a GridView to an LINQ query. Some of the fields in the objects created by the LINQ statement are strings, and need to contain new lines. Apparently, GridView HTML-encodes everything in each cell, so I can't insert a <br /> to create a new line within a cell. How do I tell GridView not to HTML encode the contents of cells? Maybe I should use a different control instead?

  • [java] Keystore change passwords

    - by user313724
    Hi, I currently have a keystore, with a particular password that only I should know. I now need to give access to that keystore to someone else, so I would like to either: 1) Change the password, so I can share it with others and let them sign 2) Create a different password and allow them to sign with it. Is this possible? and - if yes - how?

  • When a popover row is selected, how is - (void)setDetailItem:(id)newDetailItem called??

    - by dalton-hamilton
    I've created a TabBar application and in one of the views I'm using a popover. The view is registered for UIPopoverControllerDelegate but that doesn't do it. The popover is a completely different view controller and xib. When the user selects a row in the popover, control goes to the popovercontroller.m method - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath Any help would be appreciated. Best Regard Dalton Hamilton

  • What are the most common SQL anti-patterns?

    - by le dorfier
    All of us who work with relational databases have learned (or are learning) that SQL is different. Eliciting the desired results, and doing so efficiently, involves a tedious process partly characterized by learning unfamiliar paradigms, and finding out that some of our most familiar programming patterns don't work here. What are the most common antipatterns you've seen (or your self committed), whether generic or product-specific, whether in SQL statements directly, or in the ways applications build and apply them?

  • Can Nokogiri Parse a Nokogiri Object?

    - by Jesse J
    I'm trying to parse a part of the result of a parse, like this: queries = @doc.xpath("//spectrum_query") queries.each do |query| hits = query.xpath("//search_hit") end But instead of Nokogiri only searching for search_hits inside the query, it searches for search_hits in the whole document. I'm sure there's a different way to accomplish what I want, but doing it like this would be the simplest. Anyone know if it's possible to search just the query object?

  • mysql unique-constraint

    - by Cypher
    I have two tables -- Variables (id, name) and Variable_Entries (id, var_id, value). I want each variable to have a unique set of entries. If I make the value entry unique then a different variable won't be able to have that same value which is not right. Is there some way to make the value column unique for identical var_id's?

  • Allowing user to select a UIPickerView row by tapping.

    - by camilo
    Hi. I'm trying to use a UIPicker View with a behavior somehow different of what's usually seen in iPhone code examples. What I want to do is to allow users to scroll through the picker contents, but not to select a picker's row automatically (using the "didSelectRow" method from picker's delegate). Instead, I want to allow the user to touch the center row of the picker, which gets highlighted, and becomes the selection. Is there any way to achieve this? Thanks in advance.

  • sprintf in Delphi?

    - by kroimon
    Hi there! Does anyone know a 100% clone of the C/C++ printf for Delphi? Yes, I know the System.Format function, but it handles things a little different. For example if you want to format 3 to "003" you need "%03d" in C, but "%.3d" in Delphi. I have an application written in Delphi which has to be able to format numbers using C format strings, so do you know a snippet/library for that? Thanks in advance!

  • Video Game Bots?

    - by cam
    Something I've always wondered, especially since it inspired me to start programming when I was a kid, was how video game bots work? I'm sure there are a lot of different methods, but what about automation for MMORPGs? Or even FPS-type bots?

  • What'd be a good pattern on Doctrine to have multiple languages

    - by PERR0_HUNTER
    Hi! I have this challenge which consist in having a system that offers it's content in multiple languages, however a part of the data contained in the system is not translatable such as dates, ints and such. I mean if I have a content on the following YAML Corporativos: columns: nombre: type: string(254) notnull: true telefonos: type: string(500) email: type: string(254) webpage: type: string(254) CorporativosLang: columns: corporativo_id: type: integer(8) notnull: true lang: type: string(16) fixed: false ubicacion: type: string() fixed: false unsigned: false primary: false notnull: true autoincrement: false contacto: type: string() fixed: false unsigned: false primary: false notnull: true autoincrement: false tipo_de_hoteles: type: string(254) fixed: false unsigned: false primary: false notnull: true autoincrement: false paises: type: string() fixed: false unsigned: false primary: false notnull: true autoincrement: false relations: Corporativo: class: Corporativos local: corporativo_id foreign: id type: one foreignAlias: Data This would allow me to have different corporative offices, however the place of the corp, the contact and other things can be translate into a different language (lang) Now this code here would create me a brand new corporative office with 2 translations $corporativo = new Corporativos(); $corporativo->nombre = 'Duck Corp'; $corporativo->telefonos = '66303713333'; $corporativo->email = '[email protected]'; $corporativo->webpage = 'http://quack.com'; $corporativo->Data[0]->lang = 'en'; $corporativo->Data[0]->ubicacion = 'zomg'; $corporativo->Data[1]->lang = 'es'; $corporativo->Data[1]->ubicacion = 'zomg amigou'; the thing now is I don't know how to retrieve this data in a more friendly way, because if I'd like to access my Corporative info in english I'd had to run DQL for the corp and then another DQL for the specific translation in english, What I'd love to do is have my translatable fields available in the root so I could simply access them $corporativo = new Corporativos(); $corporativo->nombre = 'Duck Corp'; $corporativo->telefonos = '66303713333'; $corporativo->email = '[email protected]'; $corporativo->webpage = 'http://quack.com'; $corporativo->lang = 'en'; $corporativo->ubicacion = 'zomg'; this way the translatable fields would be mapped to the second table automatically. I hope I can explain my self clear :( any suggestions ?

  • Is One Tool or a Suite of Tools Better for Scrum?

    - by Rob Wells
    G'day, Edit: We've been using Scrum very successfully for several years on several projects of varying sizes. In fact, our team developed the successful iPlayer project for the BBC using a classical Scrum approach. After using various combinations of tools, some high-tech, some low-tech, across these projects we now wish to try adopting a suitable tool suite. Our manager is to some extent attempting to force the adoption of a single suite of tools for Scrum. I've looked at the SO question "Best Scrum tools" and most people seem to recommend either: a suite of low-tech solutions, e.g. whiteboards, post-its, index cards, etc., or a monolithic tool that tries to satisfy as much as possible of the process, e.g. Agilo, Mingle, ScrumWorks, Target Process, etc. Our team is currently evaluating several different Scrum tools. However, we are looking at selecting a single, monolithic tool, e.g. Agilo. All of the "one-stop" solutions have their strengths and weaknesses with the serious enterprise type solutions being the best sort of fit. But all have some short comings. After reading the paper "Peer Code Review: An Agile Process" over at SmartBear I started wondering if we were trying to force adoption of a tool on a "best fit" basis. I think you can take a couple of reference artefacts of the Scrum development process, say user stories, epics and themes, and the code base which must use a well-known SCM, e.g. SVN, Hg, etc. Then if we take that as the common reference points for the tools employed then we would be able to use a group of tools to handle the different aspects of the Scrum process rather than try forcing a fit of a single tool would is a bit like forcing a square peg into the round hole. In this way, providing you've agreed your common reference points, you can use several tools, each performing their role better than a could be done by a single component in a monolithic tool suite. Is this a more sensible approach? Are the two reference points I mentioned above suitable, or is their a better choice of points where the tools would meet? cheers,

  • Git for Websites / post-receive / Separation of Test and Production Sites

    - by Walt W
    Hi all, I'm using Git to manage my website's source code and deployment, and currently have the test and live sites running on the same box. Following this resource http://toroid.org/ams/git-website-howto originally, I came up with the following post-receive hook script to differentiate between pushes to my live site and pushes to my test site: while read ref do #echo "Ref updated:" #echo $ref -- would print something like example at top of file result=`echo $ref | gawk -F' ' '{ print $3 }'` if [ $result != "" ]; then echo "Branch found: " echo $result case $result in refs/heads/master ) git --work-tree=c:/temp/BLAH checkout -f master echo "Updated master" ;; refs/heads/testbranch ) git --work-tree=c:/temp/BLAH2 checkout -f testbranch echo "Updated testbranch" ;; * ) echo "No update known for $result" ;; esac fi done echo "Post-receive updates complete" However, I have doubts that this is actually safe :) I'm by no means a Git expert, but I am guessing that Git probably keeps track of the current checked-out branch head, and this approach probably has the potential to confuse it to no end. So a few questions: IS this safe? Would a better approach be to have my base repository be the test site repository (with corresponding working directory), and then have that repository push changes to a new live site repository, which has a corresponding working directory to the live site base? This would also allow me to move the production to a different server and keep the deployment chain intact. Is there something I'm missing? Is there a different, clean way to differentiate between test and production deployments when using Git for managing websites? As an additional note in light of Vi's answer, is there a good way to do this that would handle deletions without mucking with the file system much? Thank you, -Walt PS - The script I came up with for the multiple repos (and am using unless I hear better) is as follows: sitename=`basename \`pwd\`` while read ref do #echo "Ref updated:" #echo $ref -- would print something like example at top of file result=`echo $ref | gawk -F' ' '{ print $3 }'` if [ $result != "" ]; then echo "Branch found: " echo $result case $result in refs/heads/master ) git checkout -q -f master if [ $? -eq 0 ]; then echo "Test Site checked out properly" else echo "Failed to checkout test site!" fi ;; refs/heads/live-site ) git push -q ../Live/$sitename live-site:master if [ $? -eq 0 ]; then echo "Live Site received updates properly" else echo "Failed to push updates to Live Site" fi ;; * ) echo "No update known for $result" ;; esac fi done echo "Post-receive updates complete" And then the repo in ../Live/$sitename (these are "bare" repos with working trees added after init) has the basic post-receive: git checkout -f if [ $? -eq 0 ]; then echo "Live site `basename \`pwd\`` checked out successfully" else echo "Live site failed to checkout" fi

  • How to use prettify with blogger/blogspot?

    - by billpg
    Hi everyone. I'm using blogger.com to host some texts on programming, and I'd like to use prettify (same as stackoverflow) to nicely colour the code samples. How do I install the prettify scripts into the blog domain? Would it be better (if indeed its possible) to link to a shared copy somewhere? I have webspace on a different domain. Would that help? Many thanks.
