  • Is there a 3 way merger tool that “understands” common refactoring?

    - by Ian Ringrose
    When a simple refactoring like “rename field” has been done on one branch it can be very hard to merge the changes into the other branches. (Extract method is much harder as the merge tools don’t seem to match the unchanged blocks well) Now in my dreams, I am thinking of a tool that can record (or work out) what well defined refactoring operations have been done on one branch and then “replay” them on the other branch, rather than trying to merge every line the refactoring has affected. see also "Is there an intelligent 3rd merge tool that understands VB.NET" for the other half of my pain! Also has anyone try something like MolhadoRef (blog article about MolhadoRef and Refactoring-aware SCM), This is, in theory, refactoring-aware source control.

  • Creating a CLR UDF with variable number of parameters

    - by josephj1989
    Hi I wanted a function to find the greatest of a list of String values passed in. I want to invoke it as Select greatest('Abcd','Efgh','Zxy','EAD') from sql server. It should return Zxy. The number of parameters is variable.Incidentally it is very similar to oracle GREATEST function. So I wrote a very simple CLR function (Vs2008) and tried to deploy it. See below public partial class UserDefinedFunctions { [Microsoft.SqlServer.Server.SqlFunction] public static SqlString Greatest(params SqlString[] p) { SqlString max=p[0]; foreach (string s in p) max = s.CompareTo(max) > 0 ? s : max; return max; } }; But when I try to compile or deploy it I get the following error Cannot find data type SqlString[]. Is it possible to satisfy my requirement using SQL CLR ?

  • How to fire server-side methods with jQuery

    - by Nasser Hajloo
    I have a large application and I'm going to enabling short-cut key for it. I'd find 2 JQuery plug-ins (demo plug-in 1 - Demo plug-in 2) that do this for me. you can find both of them in this post in StackOverFlow My application is a completed one and I'm goining to add some functionality to it so I don't want towrite code again. So as a short-cut is just catching a key combination, I'm wonder how can I call the server methods which a short-cut key should fire? So How to use either of these plug-ins, by just calling the methods I'd written before? Actually How to fire Server methods with Jquery? You can also find a good article here, by Dave Ward Update: here is the scenario. When User press CTRL+Del the GridView1_OnDeleteCommand so I have this protected void grdDocumentRows_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) { try { DeleteRow(grdDocumentRows.DataKeys[e.Item.ItemIndex].ToString()); clearControls(); cmdSaveTrans.Text = Hajloo.Portal.Common.Constants.Accounting.Documents.InsertClickText; btnDelete.Visible = false; grdDocumentRows.EditItemIndex = -1; BindGrid(); } catch (Exception ex) { Page.AddMessage(GetLocalResourceObject("AProblemAccuredTryAgain").ToString(), MessageControl.TypeEnum.Error); } } private void BindGrid() { RefreshPage(); grdDocumentRows.DataSource = ((DataSet)Session[Hajloo.Portal.Common.Constants.Accounting.Session.AccDocument]).Tables[AccDocument.TRANSACTIONS_TABLE]; grdDocumentRows.DataBind(); } private void RefreshPage() { Creditors = (decimal)((AccDocument)Session[Hajloo.Portal.Common.Constants.Accounting.Session.AccDocument]).Tables[AccDocument.ACCDOCUMENT_TABLE].Rows[0][AccDocument.ACCDOCUMENT_CREDITORS_SUM_FIELD]; Debtors = (decimal)((AccDocument)Session[Hajloo.Portal.Common.Constants.Accounting.Session.AccDocument]).Tables[AccDocument.ACCDOCUMENT_TABLE].Rows[0][AccDocument.ACCDOCUMENT_DEBTORS_SUM_FIELD]; if ((Creditors - Debtors) != 0) labBalance.InnerText = GetLocalResourceObject("Differentiate").ToString() + "?" + (Creditors - Debtors).ToString(Hajloo.Portal.Common.Constants.Common.Documents.CF) + "?"; else labBalance.InnerText = GetLocalResourceObject("Balance").ToString(); lblSumDebit.Text = Debtors.ToString(Hajloo.Portal.Common.Constants.Common.Documents.CF); lblSumCredit.Text = Creditors.ToString(Hajloo.Portal.Common.Constants.Common.Documents.CF); if (grdDocumentRows.EditItemIndex == -1) clearControls(); } Th other scenario are the same. How to enable short-cut for these kind of code (using session , NHibernate, etc)

  • How do I correctly model data in SQL-based databases that have some columns in common, but also have

    - by Brandon Weiss
    For instance, let's say I have a User model. Users have things like logins, passwords, e-mail addresses, avatars, etc. But there are two types of Users that will be using this site, let's say Parents and Businesses. I need to store some different information for the Parents (e.g. childrens' names, domestic partner, salaries, etc.) than for the Businesses (e.g. industry, number of employees, etc.), but also some of it is the same, like logins and passwords. How do I correctly structure this in a SQL-based database? Thanks!

  • How do I combine two arrays in PHP based on a common key?

    - by Eoghan O'Brien
    Hi, I'm trying to join two associative arrays together based on an entry_id key. Both arrays come from individual database resources, the first stores entry titles, the second stores entry authors, the key=value pairs are as follows: array ( 'entry_id' => 1, 'title' => 'Test Entry' ) array ( 'entry_id' => 1, 'author_id' => 2 I'm trying to achieve an array structure like: array ( 'entry_id' => 1, 'author_id' => 2, 'title' => 'Test Entry' ) Currently, I've solved the problem by looping through each array and formatting the array the way I want, but I think this is a bit of a memory hog. $entriesArray = array(); foreach ($entryNames as $names) { foreach ($entryAuthors as $authors) { if ($names['entry_id'] === $authors['entry_id']) { $entriesArray[] = array( 'id' => $names['entry_id'], 'title' => $names['title'], 'author_id' => $authors['author_id'] ); } } } I'd like to know is there an easier, less memory intensive method of doing this?

  • Is there a Boost (or other common lib) type for matrices with string keys?

    - by mohawkjohn
    I have a dense matrix where the indices correspond to genes. While gene identifiers are often integers, they are not contiguous integers. They could be strings instead, too. I suppose I could use a boost sparse matrix of some sort with integer keys, and it wouldn't matter if they're contiguous. Or would this still occupy a great deal of space, particularly if some genes have identifiers that are nine digits? Further, I am concerned that sparse storage is not appropriate, since this is an all-by-all matrix (there will be a distance in each and every cell, provided the gene exists). I'm unlikely to need to perform any matrix operations (e.g., matrix multiplication). I will need to pull vectors out of the matrix (slices). It seems like the best type of matrix would be keyed by a Boost unordered_map (a hash map), or perhaps even simply an STL map. Am I looking at this the wrong way? Do I really need to roll my own? I thought I saw such a class somewhere before. Thanks!

  • Algorithms to find longest common prefix in a sliding window.

    - by nn
    Hi, I have written a Lempel Ziv compressor and decompressor. I am seeking to improve the time to search the dictionary for a phrase. I have considered K-M-P and Boyer-Moore, but I think an algorithm that adapts to changes in the dictionary would be faster. I've been reading that binary search trees (AVL or with splays) improve the performance of compression time considerably. What I fail to understand is how to bootstrap the binary search tree and insert/remove data. I'm not actually quite sure the significance of each node in the binary search. I am searching for phrases so will each character be considered a node? Also how and what is inserted/removed from the search tree as new data enters the dictionary and old data is removed? The binary search tree sounds like a good payoff since it can adapt to the dictionary, but I'm just not quite sure of how it's used.

  • Is it bad programming style to have a single, maybe common, generic exception?

    - by m0s
    Hi, so in my program I have parts where I use try catch blocks like this try { DirectoryInfo dirInfo = new DirectoryInfo(someString); //I don't know if that directory exists //I don't know if that string is valid path string... it could be anything //Some operations here } catch(Exception iDontCareWhyItFailed) { //Didn't work? great... we will say: somethings wrong, try again/next one } Of course I probably could do checks to see if the string is valid path (regex), then I would check if directory exists, then I could catch various exceptions to see why my routine failed and give more info... But in my program it's not really necessary. Now I just really need to know if this is acceptable, and what would a pro say/think about that. Thanks a lot for attention.

  • Mercurial How To Merge 2 Repositories that share a common ancestor but are not clones of the same re

    - by sylvanaar
    I am using hg-subversion, and I have 2 different hg repositories one from our svn trunk, and one from a branch of the trunk. I would like to link them somehow. At some point in the history both Hg repositories will be identical is there some way to join them? In other words is there a way to relate the repositories from within Hg? The technique I am currently using is to just export the second repository over top of the working copy of the revision they share, and then commit that working copy as a branch in Hg, but I lose the history this way. Any advice would be great

  • Creating Videos: Which Framerate is common in the US?

    - by Stebi
    I know that there are differences in different regions of the world regarding the framerate of videos. E.g. a DVD in Europe is in PAL with 720x756 and 25.0 fps. In the US its the NTSC standard with 720x480 and 29.97 fps. When I don't want to generate a DVD but a plain video file, e.g. WMV oder AVI what framerate is used in USA? I have a end user application where the user can generate videos, so what framerate does the US user expect it to have? Is there a difference in SD and HD video?

  • How do I join two git repos without a common root, where all modified files are the same?

    - by Evan Carroll
    I have a git-cpan-init of a repo which yielded a different root node from another already established git repo I found on github C:A:S:DBI. I've developed quite a bit on my repo, and I'd like to merge or replay my edits on a fork of the more authoritative repository. Does anyone know how to do this? I think it is safe to assume none of the file-contents of the modified files are different -- the code base hasn't been since Nov 08'. For clarity the git hub repo is the authoritative one. My local repo is the one I want to go up to git hub shown as a real git fork.

  • What are the common compliance standards for software products?

    - by Jay
    This is a very generic question about software products. I would like to know what compliance standards are applicable to any software product. I know that question gives away nothing. So, here is an example to what I am referring to. CiSecurity Security Certification/Compliance lists out products ceritified by them to be compliant to the standards published at their website, i.e, cisecurity.org. Compliance could be as simple as answering a questionnaire for your product and approved by a thirdparty like cisecurity or it could apply to your whole organization, for instance, PCI-DSS compliance. I would be very interested in knowing the standards that products you know/designed/created, comply to. To give you the context behind this question: I am the developer of a data-masking tool. The said tool helps mask onscreen html text in a banking web application using filters. So, for instance, if the bank application lists out user information with ssn, my product when integrated with the banking product, automatically identifies ssn pattern and masks it into a pre-defined format.So, I have my product marketing team wanting more buzz words like compliance to be able to sell it to more banking clients. Hence, understanding "compliances that apply to products" is a key research item for me at this point. By which I meant, security compliances. Appreciate all your help and suggestions.

  • Is use of LEAKS instrument still common on 3G iPhone?

    - by gordonmcdowell
    I'm working with an iPhone 3G, and when I'm trying to investigate memory leaks using the LEAKS instrument, my app crashes. It does not crash when LEAKS is not used. I'm making no claim to having a bug-free or non-memory-intensive app here. But I'd like to investigate leaks on an actual device. When I'm running LEAKS it is incredibly slow. Are there still developers working on iPhone 3G? I don't want to be the whiny guy blaming his tools, but I'd also like to be sure the whole dev world hasn't moved on to iPhone 3GS and I'm the only one trying to run both my app and leaks on a 3G. Currently running iOS 4.0 "gold". Snow Leopard dev env with latest XCode.
