Sending SVN commits to an RSS feed
So my favourite web tool, Subtlety, was recently discontinued, which means that I no longer have easy access to the commit logs of various SVN projects that I follow. Are there any other tools that easily pump out an RSS feed of commits for a public SVN repo?
I was going to suggest Trac as well, until I realized you probably don't have administrative control over the repositories in question. Perhaps this apparent solution will work for you? http://svnfeed.com/ It seems to work well for the one repository I tried it on, and it's surprisingly fast.

What is the easiest, most concise way to make selected attributes in an instance be readonly?
In Python, I want to make selected instance attributes of a class be readonly to code outside of the class. I want there to be no way outside code can alter the attribute, except indirectly by invoking methods on the instance. I want the syntax to be concise. What is the best way?

You should use the @property decorator. >>> class a(object):... def __init__(self, x):... self.x = x... @property... def xval(self):... return self.x... >>> b = a(5) >>> b.xval 5 >>> b.xval = 6 Traceback (most recent call last): File " ", line 1, in AttributeError: can't set attribute

What's the difference between Polymorphism and Multiple Dispatch?
...or are they the same thing? I notice that each has its own Wikipedia entry: Polymorphism, Multiple Dispatch, but I'm having trouble seeing how the concepts differ. Edit: And how does Overloading fit into all this?
Polymorphism is the facility that allows a language/program to make decisions during runtime on which method to invoke based on the types of the parameters sent to that method. The number of parameters used by the language/runtime determines the 'type' of polymorphism supported by a language. Single dispatch is a type ...

Transparently swapping pointers to character arrays in C++
I have a 2D character array: char nm[MAX1][MAX2] = { "john", "bob", "david" }; I want to swap two of these elements (without std::swap ) by simply writing swapPointers(nm[0], nm[1]); where swapPointers looks like this void swapPointers(char *&a, char *&b) { char *temp = a; a = b; b = a; } However, this does not compile...
Zan is close, but his problem is that his 'swap' function can take any pointer to characters. This can cause problems if misused. Here is a safer version: void swap(char (&x)[MAX2], char (&y)[MAX2]) { char temp[MAX2]; memcpy(temp, x, MAX2); memcpy(x, y, MAX2); memcpy(y, temp, MAX2); } There is also a misunderstanding ...

You seem to think that there is some fundamental difference between "options" that start with " -- " and "arguments" that don't. The only difference is in how you parse them.

Any quirks I should be aware of in Drupal's XML-RPC and BlogAPI implementations?
I'm beginning work on a project that will access a Drupal site to create (and eventually edit) nodes on the site, via the XML-RPC facility and BlogAPI module shipped with Drupal. This includes file uploading, as the project is to allow people to upload pictures en mass to a Drupal site with minimal ado. What I'd like t...
While the XML-RPC facility is pretty stable and works well, the BlogAPI module has various issues, especially with discovery, that make using it for anything but regular blogs painful. Currently, there is no use of blogIds in the generated Really Simple Discovery document (of which only one exists for a site) or for th...

extracting text from MS word files in python
for working with MS word files in python, there is python win32 extensions, which can be used in windows. How do I do the same in linux? Is there any library?
You could make a subprocess call to antiword. Antiword is a linux commandline utility for dumping text out of a word doc. Works pretty well for simple documents (obviously it loses formatting). It's available through apt, and probably as RPM, or you could compile it yourself.

MySQL search and replace some text in a field
What MySQL query will do a text search and replace in one particular field in a table? I.e. search for foo and replace with bar so a record with a field with the value hello foo becomes hello bar.
Change table_name and field to match your table name and field in question: UPDATE table_name SET field = REPLACE(field, 'foo', 'bar') WHERE INSTR(field, 'foo') > 0; REPLACE (string functions) INSTR (string functions)

Is there an equivalent to Ctrl-Shift-R in Safari/WebKit?
Something that would really reload the page or resource, ignoring whatever might be in cache.
Safari always reloads (ctrl+r) a page ignoring whatever that might be in the cache. As Athena points out, iframes are cached. It's actually not the iframe content, but the request that's cached. In those cases, Safari caches the page, and then no matter which link you click, shows the iframe from the last click BEFORE ...

So to combine what I think to be the best of everyone's answers: When you evaluate a variable in boolean context, its.true() method gets called. The default.true() method used by an object does a Perl 5-style <0, "", undef> check of the object's value, but when you say "but True" or "but False", this method is overridd...

I like the solution provided by Camilo above, essentially since all you're doing is altering the value of a static member, and since you do want chaining (even though it's only syntatic sugar), then instantiating TestClass is probably the best way to go. I'd suggest a Singleton pattern if you want to restrict instantia...

This allows you to pass strings as arguments to the query methods, like: var query = dataSource.Where("CategoryID == 2 && UnitPrice > 3").OrderBy("SupplierID"); Edit: Another set of posts on this subject, using C# 4's Dynamic support: Part 1 and Part 2.

How do you remotely update Java applications?

You didn't specify the type of server apps - I'm going to assume that you aren't running web apps (as deploying a WAR already does what you are talking about, and you very rarely need a web app to do pull type updates.

Try using Worksheet.Protect "Password", UserInterfaceOnly:= True If the UserInterfaceOnly parameter is set to true, VBA code can modify protected cells. Note however that this parameter does not stick. It needs to be reapplied each time the file is opened.

Implementation example for Repository pattern with Linq to Sql and C#
I am looking for a Repository pattern implementation example/resource that follows domain driven design principles for my ASP.net MVC application. Does anyone have a good example or learning resource that can be shared?
It's not an uncontroversial implementation, but Rob Conery's web storefront project has implemented repository via Linq to Sql in C#. http://blog.wekeroad.com/ Source is available. He's not quite doing strict DDD, but his TDD is generally sending him out in that direction. The one caveat is that he has multiple reposit...

Also, make sure when you write the query involving the linked server, you include brackets like this: SELECT * FROM [LinkedServer].[RemoteDatabase].[User].[Table] I've found that at least on 2000/2005 the [] brackets are necessary, at least around the server name.

When I read your question it really seems like you are describing a place to use the visitor pattern. The reason the visitor pattern should work here is an idea known as double dispatch. Your UI code will make a call and pass a reference to itself, then the class or interface ends up calling the original caller. Since ...

I have never had the issue with an dynamic image not loading without code errors. A suggestion would be to move the image generation to a handler instead of a page to avoid the additional overhead. It could be the async requests on the mobile devices getting limited.

Using glibc, why does my gethostbyname fail after I/DHCP has changed the DNS server?
If our server (running on a device) starts before a DHCP lease had been acquired then it can never connect using a hostname. If that happens it can find hosts by IP address but not by DNS. I initially thought that the Curl DNS cache was at fault as the curl connections failed. But I used CURLOPT_DNS_CACHE_TIMEOUT to pr...
It turns out that glibc gethostbyname_r won't automatically reload it's configuration if that configuration changes. You have to manually call res_init. See bug report below.

Best Way to Conditional Redirect?
Using Rails v2.1, lets say you have an action for a controller that is accessible from more than one location.

I think that using before_filter on the edit action is the least obtrusive. The referer should be reliable enough... simply have a default in the case of no referer being available (say: someone bookmarked the edit page) and you should be fine.

How to make SVN only update files but not add new ones

Don't complicate yourself. Either pull out all files (what is the disadvatage of this? a few more 100s of Ks of space?), or divide the files into several directories, and only check out the needed directories (using the 'externals' property) in relevant projects.

When there is a problem I see the standard "3 errors prohibited this foobar from being saved" on my web page along with the individual problems.

The error_messages_for helper that you are using to display the errors accepts a:header_message option that allows you to change that default header text. As in: error_messages_for 'model',:header_message => "You have some errors that prevented saving this model" The RubyOnRails API is your friend.

What are the advantages of using the C++ Boost libraries?
So, I've been reading through and it appears that the Boost libraries get used a lot in practice (not at my shop, though). Why is this? and what makes it so wonderful?
Boost is used so extensively because: It is open-source and peer-reviewed. It provides a wide range of platform agnostic functionality that STL missed. It is a complement to STL rather than a replacement. Many of Boost developers are on the C++ standard committee. In fact, many parts of Boost is considered to be includ...

Boost dependency for a C++ open source project?
Boost is meant to be the standard non-standard C++ library that every C++ user can use. Is it reasonable to assume it's available for an open source C++ project, or is it a large dependency too far?
Basically your question boils down to “is it reasonable to have [free library xyz] as a dependency for a C++ open source project.” Now consider the following quote from Stroustrup and the answer is really a no-brainer: Without a good library, most interesting tasks are hard to do in C++; but given a good library, almos...

Why do you need to eliminate the low-level locking? Do you have deadlock issues? Do you have performance problems? Or scaling issues? Are the locks generally contended or uncontended?

Setting default language in EPiServer?
I'm looking for a way to set the default language for visitors comming to a site built in EPiServer for the first time. Not just administrators/editors in the backend, people comming to the public site.
Depends on your setup. If the site languages is to change under different domains you can do this. Add to configuration -> configSections nodes in web.config:..and add this to episerver node in web.config: Otherwhise you can do something like this. Add to appSettings in web.config:

Should .NET developers *really* be spending time learning C for low-level exposure?
When Joel Spolsky and Jeff Atwood began the disagreement in their podcast over whether programmers should learn C, regardless of their industry and platform of delivery, it sparkled quite an explosive debate within the developer community that probably still rages amongst certain groups today. I have been reading a num...
I already know C and that helped me during the 1.1 days where there are a lot of things that are not yet in the.NET base libraries and I have to P/Invoke something from the Platform SDK. My take is that we should always allocate a time for learning something that we don't know yet. To answer your question, I don't thin...

Managing ThreadPool starvation within a multithreaded work queue processor?
I am investigating the design of a work queue processor where the QueueProcessor retrieves a Command Pattern object from the Queue and executes it in a new thread.

For simple cases like this an additional monitoring thread that can spin off more threads on demand is helpful. Basically every N seconds check to see if any jobs have been finished, if not, add another thread. This won't necessarily handle even more complex deadlock problems, but it will solve this one. My recommendat...

MS-SQL Server 2005: Initializing a merge subscription with alternate snapshot location

I would like to be able to execute an external editor (such as vi), and wait for the editor to finish execution before resuming the script. My basic idea was to use a temporary file to do the editing in, and to retrieve ...
You can redirect the editor's output to the terminal: system("vim > `tty`");
