I'm going to answer my own question. To treat Dictionaries as sets, the simplest method seems to be to apply set operations to dict.Keys, then convert back to Dictionaries with Enumerable.ToDictionary(...). |
How to list directory content of remote FTP, recursively |
|ftp| |
After downloading files from a remote UNIX FTP server, you want to verify that you have downloaded all the files correctly. Minimal you will get information similar to "dir /s" command in Windows command prompt. The FTP client runs on Windows. |
I am setting up a project using Hibernate 3.3.1 GA and PostgreSQL 8.3. I've just created a database, the first table, added one row there and now configuring Hibernate.

List result = criteria.list();

I think the easiest way is to get a free SVN server through some free provider. I use [assembla](http://www.assembla.com/).
Then, if you are in Windows, you should download [TortoiseSVN](http://tortoisesvn.tigris.org/). That is by far the easiest Subversion client to use.

What I would do is open up cursors on the following queries:
SELECT * from table1 order by id
SELECT * from table1 r, table2 t where t.table1_id = r.id order by r.id

And then I would walk those cursors in parallel, printing your... |
IIS ASP Caching |

I'm trying to configure ASP caching in IIS, following the instructions of a software I purchased. This is supposed to make it run faster.

I reccomend SVN to start off with, bit easier to get the hang of than some others.
[Tortoise][1] is a good start. It's simple to install and integrates with the windows shell, meaning everything is fairly intuitive on Right-clicks on folders / files etc. Pretty good doc as well.

I assume you simply check whether or not the name of the checkbox was posted to the server or not. Not being an ASP coder myself, I can't help, though this is how it would be done in PHP (of course, depending on how you map validations).
<?php echo isset($_POST['checkbox_name']) ? 'checked' : 'not checked'; ?> |
What might be going wrong is the selection is being changed inside the selection change message handler which result in another selection change message.

I use Jython for *interactive* testing of Java code. This is often much faster than writing Java test applications or even any scripting language. I can just play with the methods and see how it reacts. From there I can learn enough to go and write some real code or test cases. |
Loads!
JQuery, Prototype, ExtJS, Dojo, Mootools, YUI, Mochikit, the list goes on!
JQuery is very popular, and an excellent choice, however some frameworks are better for some things, and others better for others. If you could give us a better idea of what you want to do, or how you will be using it (or even which... |
And let's not forget about `<<` for example:

string << "ing"
is the same as calling:
string.<<("ing")

MIPS Assembly Pointer to a Pointer? |

I think I know how to handle this case, but I just want to make sure I have it right. Say you have the following C code:

P contains an address that points to a place in memory which has another address. I'd like to modify the... |
In most scripting langage (it's also true in Bash for instance), simple quotes are used to represent things as they are written, whereas double quotes are "analysed" (i don't think it's the appropriate word but i can't find better).

There is a simple tool in TortoiseSVN named **SubWCRev.exe**. It takes revision from *path* and create file from your own template. You can use it as prebuild command. |
- `ctrl+shift+K` deletes current line

The sample below shows how I do it
- SavePreferences is called when closing the form and saves the form's size, and a flag indicating if it's maximized (in this version I don't save if it's minimized - it will come back up restored or maximized next time).
- LoadPreferences is called from OnLoad.

You can add and remove a special CSS class and modify the input value onfocus/onblur with JS:

In solutions with multiple projects, one thing I've found very helpful is to have all the AssemblyInfo files point to a single project that governs the versioning. So my AssemblyInfos have a line:

find_if appears to be the right choice here. The predicate isn't stateful in this situation.

Of the options provided, I'd go with

simply by virtue of the braces being habit to type.

I'm fairly surprised at how unanimous the sentiment is that getters and setters are fine and good.

Granted, the title is for shock value, but the author makes ... |
If you have ssh access, use rsync instead. It is a far better data transfer app.

[Jinja2][1] syntax is pretty much the same as Django's and you get a much more robust template engine, witch compiles your template to bytecode (FAST!).

In my opinion if you already have Viual Source Safe and you are a single developer doing work with VS, it is perfectly fine. Its a simple system that works well enough for small single developer projects. I have used it for years without any trouble for small projects. Easy to manage and backup as well. |

Maybe I misunderstand, but the ArrayList will maintain its elements in the same order by which you added them. This means you can compare the two ArrayLists within one pass only - just increment the two scanning indices according to the comparison results. |
One question I have is have you considered "out-sourcing" your comparison. There are plenty of good diff tools that you could just call out to. I'd be surprised if there wasn't one that let you specify two files and get only the differences. Just a thought. |
From my search, I have not found any good multi-thread debuggers for *nix. GDB seems to be getting better, and the last time I had to debug a multi-threaded application on FreeBSD (7.0-RELEASE) it behaved fairly well, letting me find where the error was. |
I once looked for a gdb alternative, but unfortunately every one I found was based on gdb. I think this is because gdb is intricately tied to gcc, and it's hard for third-party debuggers to keep up with every gcc change. |
If you really want inheritance, don't forget that you can [implement the enum pattern yourself][1], like in the bad old Java 1.4 days.

System.Collections.Specialized.StringCollection allows you to add a range of values and, using the .IndexOf(string) method, allows you to retrieve the index of that item.
