  • SVN: is it possible to delete a branch that was copied removed etc for good?

    - by dimus
    I have to remove a branch from svn history for good. Normally I would use svnadmin dump /path/to/repo |svndumpfilter --drop-empty-revs --renumber-revs exclude /branches/bad_branch However this branch was not just created, but also moved and then removed and dump script fails to process downstream information with messages like: Invalid copy source path '/branches/bad_branch' So I imagine 2 ways to cope with the problem keep only last few revisions of the history and put current repository as an archive on the web make a dump up to the revision where the 'bad_branch' was created and apply the rest of the changes as a patch, therefore losing history of a few recent commits. Is there a better, cleaner way to deal with this?

  • is it possible to achieve an image clipping/masking effect with html + css3?

    - by sa125
    Hi - I'm trying to place a nice border around an image that's 250x250, using only html and css. The markup is this: <div id="img-container"><img src="pic.jpg" border="0"/></div> And the css is: #img-container { height: 225px; width: 225px; padding: 3px; border: 1px solid black; z-index: 10; position: relative; overflow: hidden; border-radius: 10px; } #img-container img { z-index: 5; } Basically, I want the div container to clip the picture's edges that exceed its boundaries. This will achieve the rounded edges effect using the border-radius property (-moz-border-radius, -webkit-border-radius, etc) - if it actually works or could even be done. Looking for tips and tricks on this. Thanks. And, yes, I'm obviously not a web designer :)

  • Is it possible to convert a 40-character SHA1 hash to a 20-character SHA1 hash?

    - by ewitch
    My problem is a bit hairy, and I may be asking the wrong questions, so please bear with me... I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this: hashedsalt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") hashedpassword = Digest::SHA1.hexdigest("#{hashedsalt}:#{password}") So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data. But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related. So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle... Thanks in advance for any insight.

  • Is it possible to read to a Paradox 7.x .db file in a .Net app?

    - by Pedro
    I'm trying to read a Paradox 7.x .db file in a .Net 3.5 app and I'm not being successful on that. First of all, when I'm registering the odbc, as a user or system dsn, the Microsoft Paradox ODBC Driver only display versions up to 5.x, so it looks like that it does not support Paradox version 7.x. At connectionsstrings.com I've found the connection string that is supposed to work with Paradox 7.x: Provider=MSDASQL;Persist Security Info=False;Mode=Read; Extended Properties='DSN=Paradox;DBQ=C:\mydbfolder; DefaultDir=C:\mydbfolder;DriverId=538;FIL=Paradox 7.X;MaxBufferSize=2048; PageTimeout=600;';Initial Catalog=C:\mydbfolder But when I try to test the connection using a Data Adapter I get the following exception: "ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified" I have specified the ODBC as a user DSN and as a System DSN as well but kept receiving the same error. Any clues on what should I do? Thanks, Pedro

  • Is it possible to restore a previous GL framebuffer?

    - by Rob
    Hi there, I'm working on an iPhone app that lets the user draw using GL. I used the GLPaint sample code project as a firm foundation, but now I want to add the ability for the user to load one of their previous drawings and continue working on it. I know how to get the framebuffer contents and save it as a UIImage. Is there a way for me to take the UIImage and tell GL to draw that? Any help is much appreciated.

  • Is it possible in any Java IDE to collapse the type definitions in the source code?

    - by asmaier
    Lately I often have to read Java code like this: LinkedHashMap<String, Integer> totals = new LinkedHashMap<String, Integer>(listOfRows.get(0)) for (LinkedHashMap<String, Integer> row : (ArrayList<LinkedHashMap<String,Integer>>) table.getValue()) { for(Entry<String, Integer> elem : row.entrySet()) { String colName=elem.getKey(); int Value=elem.getValue(); int oldValue=totals.get(colName); int sum = Value + oldValue; totals.put(colName, sum); } } Due to the long and nested type definitions the simple algorithm becomes quite obscured. So I wished I could remove or collapse the type definitions with my IDE to see the Java code without types like: totals = new (listOfRows.get(0)) for (row : table.getValue()) { for(elem : row.entrySet()) { colName=elem.getKey(); Value=elem.getValue(); oldValue=totals.get(colName); sum = Value + oldValue; totals.put(colName, sum); } } The best way of course would be to collapse the type definitions, but when moving the mouse over a variable show the type as a tooltip. Is there a Java IDE or a plugin for an IDE that can do this?

  • Is it possible for competing file access to cause deadlock in Java?

    - by BlairHippo
    I'm chasing a production bug that's intermittent enough to be a real bastich to diagnose properly but frequent enough to be a legitimate nuisance for our customers. While I'm waiting for it to happen again on a machine set to spam the logfile with trace output, I'm trying to come up with a theory on what it could be. Is there any way for competing file read/writes to create what amounts to a deadlock condition? For instance, let's say I have Thread A that occasionally writes to config.xml, and Thread B that occasionally reads from it. Is there a set of circumstances that would cause Thread B to prevent Thread A from proceeding? My thanks in advance to anybody who helps with this theoretical fishing expedition. Edit: To answer Pyrolistical's questions: the code isn't using Filelock, and is running on a WinXP machine.

  • Is it possible to reference the Azure SDK 1.1 Microsoft.WindowsAzure.* assemblies from a .NET 4.0 Cl

    - by tjrobinson
    I have a WPF application targetting the .NET 4.0 Client Profile which needs to use the Microsoft.WindowsAzure.* assemblies provided in the Windows Azure SDK 1.1. The problem is that these assemblies have a runtime version of v2.0.50727. I am able to add references to them from my WPF project but they're not recognised. I've read about the side by side execution capabilities of .NET 4.0 but does this require both the .NET 2.0 and the .NET 4.0 frameworks to be installed? Is there anything from Microsoft on when a new SDK might be available that contains assemblies targeting .NET 4.0?

  • Is it possible to "merge" the values of multiple records into a single field without using a stored

    - by j0rd4n
    A co-worker posed this question to me, and I told them, "No, you'll need to write a sproc for that". But I thought I'd give them a chance and put this out to the community. Essentially, they have a table with keys mapping to multiple values. For a report, they want to aggregate on the key and "mash" all of the values into a single field. Here's a visual: --- ------- Key Value --- ------- 1 A 1 B 1 C 2 X 2 Y The result would be as follows: --- ------- Key Value --- ------- 1 A,B,C 2 X,Y They need this in SQLServer 2005. Again, I think they need to write a stored procedure, but if anyone knows a magic out-of-the-box function that does this, I'd be impressed.

  • Is it possible to configure a Spring session scoped bean with attributes from the session?

    - by Dave G
    I'm trying to create a service bean that when referenced will be initialized with HttpSession based attributes. Let's say for sake of argument that my webapp would do the following: Establish a session Request login & password When service is requested (it is scope="session" and has init-method="init()") a new instance is created for the session. In the init method, can I reference the HttpSession either through passing it in as a parameter and referencing it by EL? Any ideas on this would be appreciated.

  • Is it possible to easily convert SqlCommand to T-SQL string ?

    - by Thomas Wanner
    I have a populated SqlCommand object containing the command text and parameters of various database types along with their values. What I need is a T-SQL script that I could simply execute that would have the same effect as calling the ExecuteNonQuery method on the command object. Is there an easy way to do such "script dump" or do I have to manually construct such script from the command object ?

  • C# immutable object usage best practices? Should I be using them as much as possible?

    - by Daniel
    Say I have a simple object such as class Something { public int SomeInt { get; set; } } I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such: class ImmutableSomething { public int SomeInt { get { return m_someInt; } } private int m_someInt = 0; public void ChangeSomeInt(int newValue) { m_someInt = newvalue; } } What do you reckon?

  • How can I create a dynamic LINQ query in C# with possible multiple group by clauses?

    - by FordPrefect141
    I have been a programmer for some years now but I am a newcomer to LINQ and C# so forgive me if my question sounds particularly stupid. I hope someone may be able to point me in the right direction. My task is to come up with the ability to form a dynamic multiple group by linq query within a c# script using a generic list as a source. For example, say I have a list containing multiple items with the following structure: FieldChar1 - character FieldChar2 - character FieldChar3 - character FieldNum1 - numeric FieldNum2 - numeric In a nutshell I want to be able to create a LINQ query that will sum FieldNum1 and FieldNum2 grouped by any one, two or all three of the FieldChar fields that will be decided at runtime depending on the users requirements as well as selecting the FieldChar fields in the same query. I have the dynamic.cs in my project which icludes a GroupByMany extension method but I have to admit I am really not sure how to put these to use. I am able to get the desired results if I use a query with hard-wired group by requests but not dynamically. Apologies for any erroneous nomenclature, I am new to this language but any advice would be most welcome. Many thanks Alex

  • Possible to recover mysql root pass with sudo server access?

    - by jonathonmorgan
    I've inherited development for a website on vps hosting, and have login info for a user with sudo privileges, but don't have the password for the mysql root user. After digging around a little, it looks like the only way to fix this is to stop mysql (something like this: http://waoewaoe.wordpress.com/2010/02/03/recover-reset-mysql-root-password/). But because the website it's serving is currently in production, I'm hoping you guys can enlighten me to any potential consequences (or let me know if there's typically a file where the password would be accessible). a) during the time mysql is stopped, information in the database won't be accessible, right -- even by other users? b) will resetting the root password have any impact on other users after mysql has restarted? Will their username/passwords still be valid? The current application is using an account with limited privileges to read/write to the database, and while 5min downtime in the middle of the night would probably go unnoticed, half a day while I tie up loose ends/figure out what I screwed up will land in me hot water. Thanks in advance for your help!
