  • What CI server and Configuration Management tools I should use

    - by Bera
    Hi ! What CI server and Configuration Management tools I should use together for a truly development and deploy maintenance. There isn't the de facto rails sustainable environment, is there? Some assumptions: • code control version ok - git (de facto tool) • test framework ok - whatever (rspec is my choice) • code coverage and analysis ok - whatever (metric-fu, for example) • server stack ok - (Passenger for example) • issue tracker (RedMine) • etc, ... I'm want to play if integrity and moonshine projects, for me it's a good for beginning, isn't it? What do you think about this? Thanks, Bruno

  • Signup form using Braintree Transparent Redirect

    - by Robin Fisher
    Hi, I'm developing an application in Rails and want the user to be able to signup and provide their card details on one form. I'm using the Braintree API and their transparent redirect, which means that the form data is posted directly to Braintree. How can I store and later retrieve the non-payment related information provided by the user from that form e.g. account name, username? These values are not returned in the response provided by Braintree. If you look at the Basecamp signup process, this is the result I want to achieve. Thanks Robin

  • one primary key column foreign key to 2 other table columns.How to resolve data entry issue.

    - by Rohit
    I have a requirement according to which I have to create a central Login system.We have 2 things Corporate and Brand each represented by tables "Corporate" and "Brand". When a corporate gets registered,corporateID is given,When a user under that corporate gets registered there is a table corporateuser in which corporateID is a foreign key and CorporateUserID is a primary key.Similarly in the case of a brand. So we have CorporateUserId and BrandUserID. Now i have a table called RegisteredUsers in which i want to have corporate as well as brand users.UserID is a primary key in this table which is a foreign key to both corporateuser as well as Branduser. now when i enter a corporateuser,I do an entry to corporateuser as well as RegisteredUsers.When i enter CorporateUserID in userID for RegisteredUsers.It gives foreign key violation error. I fully understand this error.How can i achieve this.This requirement is very rigid.Please tell a workaround

  • Have you ever bought a commercial implementation of a programming language for personal programming

    - by Nelson
    Commercial products are often a source of ideas and inspiration for open source projects. There are free and open source implementations of almost every programming language ever devised, and a lot of them are very good. For non-work related personal programming projects, have you ever bought an expensive commerical implementation of a programming language and found it well worth the investment? If so, which one and why?

  • Export products and variants from MSSQL

    - by mickyjtwin
    I have a SQL DB that has a table of products, and another table which contains a list of the sku variants of each product if it has one. I want to export all the products and their SKU's into excel. At the moment, I have a helper SQL function which performs the subquery against a product_id and concatenates all the SKU's into a comma-delimited string, e.g: Product Code, Name, SKUs 111 P1 77, 22, 11 Is there an easier way to do this, so that each SKU is a row which the associated product code as well, i.e: Product Code, Name, SKUs 111 P1 77 111 P1 22 111 P1 11

  • Is this text wrapping technique possible in CSS and jQuery?

    - by alex
    I have built a sliding text thing for a website. http://www.solomonadventures.com/~new/adventure-tours/seafari-tours/ The background contains the menu (on the right hand side), and when it originally loads, I have placed an element to make the text look like it is wrapping around the menu. Now, I have a sliding text thing I was asked to implement. The buttons to use it are currently in the top left corner. My question is, when I slide the content down, am I able to somehow make the text still wrap around it? This is all I have thought of so far (all with trade offs) Make the text appear beneath the menu - no need to wrap Make the text as narrow to the beginning of the menu - no need to wrap Manually place placeholders in the text that make it line break so it appears to wrap - not elegant (site uses a CMS too) Is there any jQuery selector I could write that would allow me to select the paragraph from top (once slid to the top) or the top most text node (so I could do an after() to place a new placeholder element to force it to wrap?) Any other solutions? Many thanks.

  • Per-machine decentralised DNS caching - nscd/lwresd/etc

    - by Dan Carley
    Preface: We have caching resolvers at each of our geographic network locations. These are clustered for resiliency and their locality reduces the latency of internal requests generated by our servers. This works well. Except that a vast quantity of the requests seen over the wire are lookups for the same records, generated by applications which don't perform any DNS caching of their own. Questions: Is there a significant benefit to running lightweight caching daemons on the individual servers in order to reduce repeated requests from hitting the network? Does anyone have experience of using [u]nscd, lwresd or dnscache to do such a thing? Are there any other packages worth looking at? Any caveats to beware of? Besides the obvious, caching and negative caching stale results.

  • MSExchangeMailSubmission service is not listed or running; sent mail not working

    - by InterMurph
    I am running a new Exchange 2007 SP1 system. I moved the mailboxes from the old Exchange 2003 server, and incoming mail is working. But outgoing mail is not working at all; even inside my domain. Lots of debugging and searching lead me to believe that the problem is that the "Microsoft Exchange Mail Submission Service" (AKA MSExchangeMailSubmission) is not running. In fact, it's not even listed in the Services list. This document (http://technet.microsoft.com/en-us/library/aa998342.aspx) says that this service is installed by the Mailbox server role. My server is running the Mailbox role, as well as the Hub Transport and Client Access roles. How do I get this service to show up in the list, so that I can start it up? Thanks.

  • How to associate the ".exe" extension to be opened with Mono?

    - by wuser
    I want to asssociate the .exe file extension to Mono (don't care about wine). Apparently, when using Finder's GUI, only .app files (application bundles) can be selected. But the Mono executable (/Libraries/Frameworks/Mono.Framework/Current/bin/mono) is no such bundle. I tried some AppleScript on run this_file do shell script "mono this_file &" end run but Finder's GUI still doesn't allow to associate that with .exe's. How to associate a specific file extension to a command-line application in Mac OS X?

  • How to choose my own filename format for subscribed podcast files?

    - by meomaxy
    I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

  • What resources will help me understand the fundamentals of Relational Database Design.

    - by Rachel
    This are few of the fundamental database questions which has always given me trouble. I have tried using google and wiki but I somehow I miss out on understanding the functionality rather than terminology. If possible would really appreciate if someone can share more insights on this questions using some visual representative examples. What is a key? A candidate key? A primary key? An alternate key? A foreign key? What is an index and how does it help your database? What are the data types available and when to use which ones?

  • OpenLayers: Raise event when map is zoomed or moved by user

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom, and fitting the current view port. This should be relatively easy to do using the GetResolution and CalculateBounds methods on the Map object. However, I don't know when to call these methods because I can't find a way to register a function to be called when the user pans the map (changing the view port) or zooms the map (changing the resolution and view port). How can I get a callback when the user pans or zooms the map?

  • How does the recursion here work?

    - by David
    code 1: public static int fibonacci (int n){ if (n == 0 || n == 1) { return 1; } else { return fibonacci (n-1) + fibonacci (n-2); } } how can you use fibonacci if you haven't gotten done explaining what it is yet? I've been able to understand using recursion in other cases like this: code two: class two { public static void two (int n) { if (n>0) { System.out.println (n) ; two (n-1) ; } else { return ; } } public static void main (String[] arg) { two (12) ; } } In the case of code 2 though n will eventualy reach a point at which it doesnt satisfy n0 and the method will stop calling itself recursivly. in the case of code 2 though i don't see how it would be able to get itself from 1 if n=1 was the starting point to 2 and 3 and 5 and so on. Also i don't see how the line `return fibonacci (n-1) + fibonacci (n-2) would work since fibbonacci n-2 has to contain in some sense fibonacci n-1 in order to wrok but it isn't there yet. I know my question is worded poorly but looking at this is making my mind explode. the book i'm looking at says it will work. how does it work? `

  • How to Break out of multiple loops at once in C#?

    - by Rosarch
    What if I have nested loops, and I want to break out of all of them at once? while (true) { // ... while (shouldCont) { // ... while (shouldGo) { // ... if (timeToStop) { break; // break out of everything? } } } } In PHP, break takes an argument for the number of loops to break out of. Can something like this be done in C#? What about something hideous, like goto? // in the innermost loop goto BREAK // ... BREAK: break; break; break;
