I'm trying out the following query:
```
SELECT A,B,C FROM table WHERE field LIKE 'query%'
UNION
SELECT A,B,C FROM table WHERE field LIKE '%query'
UNION
SELECT A,B,C FROM table WHERE field LIKE '%query%'
GROUP BY B ORDER BY B ASC LIMIT 5
```
That's three queries stuck together, kinda sorta. However, the result set that comes back reflects results from query #3 before the results from query #1 which is undesired.
Is there any way to prioritize these so that results come as all for query #1, then all for query #2 then all for query #3? I don't want to do this in PHP just yet (not to mention | [

Maybe you should try including a fourth column, stating the table it came from, and then order and group by it:

After being told by at least 10 people on SO that version control was a good thing even if it's just me I now have a followup question.
What is the difference between all the different types of version control and is there a guide that anybody knows of for version control that's very simple and easy to understand?
Eric Sink has a [good overview of source control](http://www.ericsink.com/scm/source_control.html).

I have a simple setter method for a property and `null` is not appropriate for this particular property. I have always been torn in this situation: should I throw an [`IllegalArgumentException`](http://docs.oracle.com/javase/7/docs/api/java/lang/IllegalArgumentException.html), or a [`NullPointerException`](http://docs.oracle.com/javase/7/docs/api/java/lang/NullPointerException.html)? From the javadocs, both seem appropriate. Is there some kind of an understood standard? Or is this just one of those things that you should do whatever you prefer and both are really correct?
It seems like an `IllegalArgumentException` is called for if you don't want `null` to be an allowed value, and the `NullPointerException` would be thrown if you were trying to *use* a variable that | [

Since the WMI class Win32\_OperatingSystem only includes OSArchitecture in Windows Vista, I quickly wrote up a method using the registry to try and determine whether or not the current system is a 32 or 64bit system.
```
private Boolean is64BitOperatingSystem()
{
RegistryKey localEnvironment = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment");
String processorArchitecture = (String) localEnvironment.GetValue("PROCESSOR_ARCHITECTURE");
if (processorArchitecture.Equals("x86")) {
return false;
}
else {
return true;
}
}

I'm not sure how much I like looking through the registry. Is this a pretty standard practice or is there a better method?
**Edit**: Wow, that code looks a lot prettier in the preview. I'll consider linking to a pastebin or something, next time.
Take a look at Raymond Chens solution:
[How to detect programmatically whether you are running on 64-bit Windows](http://blogs.msdn.com/oldnewthing/archive/2005/02/01/364563.aspx)
and here's the PINVOKE for .NET:
[IsWow64Process (kernel32)](http://www.pinvoke.net/default.aspx/kernel32/IsWow64Process.html?diff=y)

I have Windows File sharing enabled on an OS X 10.4 computer. It's accessible via \rudy\myshare for all the Windows users on the network, except for one guy running Vista Ultimate 64-bit edition.
All the other users are running Vista or XP, all 32-bit. All the workgroup information is the same, all login with the same username/password.
The Vista 64 guy can see the Mac on the network, but his login is rejected every time.
Now, I imagine that Vista Ultimate is has something configured differently to the Business version and XP but I don't really know where to look. Any ideas?

```
svn merge -r 67212:67213 https://my.svn.repository/trunk .

I only had 2 files, one of which is a simple `ChangeLog`. Rather than just merging my `ChangeLog` changes, it actually pulled mine plus some previous ones that were not in the destination `ChangeLog`. I noticed there was a conflict when I executed --dry-run, so I updated `ChangeLog`, and there was still a conflict (and I saw the conflict when I did the actual merge).
I then later diffed on the file I was merging from:

I know that extra changes didn't get in there somehow.
This makes me worried that merge is not actually just taking what I changed, which is what I would have expected. Can anybody explain what happened?

So, I have 2 files changed, only ChangeLog is relevant, the other merged fine. When I go to my regular trunk checkout, I do the diff command above and see:

This only happens with conflicts - basically svn tried to merge the change in, but (roughly speaking) saw the change as:

I plan to be storing all my config settings in my application's app.config section (using the `ConfigurationManager.AppSettings` class). As the user changes settings using the app's UI (clicking checkboxes, choosing radio buttons, etc.), I plan to be writing those changes out to the `AppSettings`. At the same time, while the program is running I plan to be accessing the `AppSettings` constantly from a process that will be constantly processing data. Changes to settings via the UI need to affect the data processing in real-time, which is why the process will be accessing the `AppSettings` constantly.
Is this a good idea with | [

regard to performance? Using `AppSettings` is supposed to be "the right way" to store and access configuration settings when writing .Net apps, but I worry that this method wasn't intended for a constant load (at least in terms of settings being constantly read).
If anyone has experience with this, I would greatly appreciate the input.
**Update:** I should probably clarify a few points.
This is not a web application, so connecting a database to the application might be overkill simply for storing configuration settings. This is a Windows Forms application.

settings, but user settings as well. (Especially important if, for instance, the application is installed as a partial-trust application.)
**Update 2:** I accepted lomaxx's answer because `Properties` does indeed look like a good solution, without having to add any additional layers to my application (such as a database). When using Properties, it already does all the caching that others suggested. This means any changes and subsequent reads are all done in memory, making it extremely fast. Properties only writes the changes to disk when you explicitly tell it to. This means I can make changes to the config settings on-the-fly at | [

Just to verify it would actually be able to handle the load I need, I did some testing on my laptop and was able to do 750,000 reads and 7,500 writes per second using Properties. That is so far above and beyond what my application will *ever* even come close to needing that I feel quite safe in using Properties without impacting performance.

Is there a trivial, or at least moderately straight-forward way to generate territory maps (e.g. Risk)?
I have looked in the past and the best I could find were vague references to Voronoi diagrams. An example of a Voronoi diagram is this:
.
These hold promise, but I guess i haven't seen any straight-forward ways of rendering these, let alone holding them in some form of data structure to treat each territory as an object.
Another approach that holds promise is flood fill, but again I'm unsure on the best way to start with this approach.
Any advice would be much appreciated.

seen on them is [Computational Geometry: Algorithms and Applications](https://rads.stackoverflow.com/amzn/click/com/3540779736), which covers Voronoi diagrams, Delaunay triangulations (similar to Voronoi diagrams and each can be converted into the other), and other similar data structures.
They talk about all the data structures you need but they don't give you the code necessary to implement it (which may be a good exercise). In terms of code, an Amazon search shows the book [Computational Geometry in C](https://rads.stackoverflow.com/amzn/click/com/0521649765), which presumably comes with the code (although since you're stuck in C, you'd mind as well get the other one and implement it in whatever language you want). | [

I want to convert a primitive to a string, and I tried:
```
myInt.toString();
```
This fails with the error:
```
int cannot be dereferenced
```
Now, I get that primitives are not reference types (ie, not an Object) and so cannot have methods. However, Java 5 introduced autoboxing and unboxing (a la C#... which I never liked in C#, but that's beside the point). So with autoboxing, I would expect the above to convert myInt to an Integer and then call toString() on that.
Furthermore, I believe C# allows such a call, unless I remember incorrectly. Is this just an unfortunate shortcoming of Java's autoboxing/unboxing specification, or is | [

there a good reason for this?
Java autoboxing/unboxing doesn't go to the extent to allow you to dereference a primitive, so your compiler prevents it. Your compiler still knows `myInt` as a primitive. There's a paper about this issue at [jcp.org](http://jcp.org/aboutJava/communityprocess/jsr/tiger/autoboxing.html).
Autoboxing is mainly useful during assignment or parameter passing -- allowing you to pass a primitive as an object (or vice versa), or assign a primitive to an object (or vice versa).
So unfortunately, you would have to do it like this: (kudos Patrick, I switched to your way)
```
Integer.toString(myInt);

1. Which are the definitive HTTP headers that I need to check in order to know for sure whether I should send a 304 response, and what am I looking for when I do check them?
2. Additionally, are there any headers that I need to send when I initially send the file (like 'Last-Modified') as a 200 response?
Some psuedo-code would probably be the most useful answer.

What about the cache-control header? Can | [

the various possible values of that affect what you send to the client (namely max-age) or should only if-modified-since be obeyed?
Here's how I implemented it. The code has been working for a bit more than a year and with multiple browsers, so I think it's pretty reliable. This is based on [RFC 2616](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html) and by observing what and when the various browsers were sending.
Here's the pseudocode:
```
server_etag = gen_etag_for_this_file(myfile)
etag_from_browser = get_header("Etag")
if etag_from_browser does not exist:
etag_from_browser = get_header("If-None-Match")
if the browser has quoted the etag:
strip the quotes (e.g. "foo" --> foo)
set server_etag into http header

Here's a snippet of my server logic that handles this.

Using MAPI functions from within managed code is officially unsupported. Apparently, MAPI uses its own memory management and it crashes and burns within managed code (see [here](http://blogs.msdn.com/pcreehan/archive/2007/05/04/what-does-unsupported-mean.aspx) and [here](http://blogs.msdn.com/mstehle/archive/2007/10/03/fyi-why-are-mapi-and-cdo-1-21-not-supported-in-managed-net-code.aspx))

Have a separate helper EXE that takes command-line params (or pipe to its StandardInput) that does what is required and call that from your main app. This keeps the MAPI stuff outside of your main app's process space. OK, you're still mixing MAPI and .NET but in a very short-lived process. The assumption is that MAPI and the CLR start causing issues with longer-running processes.

How do I generate an ETag HTTP header for a resource file?
An etag is an arbitrary string that the server sends to the client that the client will send back to the server the next time the file is requested.
The etag should be computable on the server based on the file. Sort of like a checksum, but you might not want to checksum every file sending it out.
```
server client
<------------- request file foo
file foo etag: "xyz" | [

etag: "xyz" (what the server just sent)
(the etag is the same, so the server can send a 304)
```
I built up a string in the format "datestamp-file size-file inode number". So, if a file is changed on the server after it has been served out to the client, the newly regenerated etag won't match if the client re-requests it.

To analyze lots of text logs I did some hackery that looks like this:
1. Locally import logs into Access
2. Reprocess Cube link to previous mdb in Analisis Service 2000 (yes it is 2k)
3. Use Excel to visualize Cube (it is not big - up to milions raw entries)
My hackery is a succes and more people are demanding an access to my Tool. As you see I see more automating and easier deployment.

I'm trying to create a bookmarklet for posting del.icio.us bookmarks to a separate account.

Does anyone remember the `XMP` tag?
What was it used for and why was it deprecated?
A quick Google search on W3C reveals that `XMP` was introduced for displaying **preformatted text** in HTML 3.2 and earlier. When W3C deprecated the `XMP` tag, it suggested using the `PRE` tag as a preferred alternative.

I am currently aware that ASP.NET 2.0 is out and about and that there are 3.x versions of the .Net Framework.
Is it possible to upgrade my ASP.NET web server to version 3.x of the .Net Framework?

I have tried this, however, when selecting which version of the .Net framwork to use in IIS (the ASP.NET Tab), only version 1.1 and 2.0 show.
Is there a work around?

Yes, that is correct. You have IIS set to 2.0 for both 2.0 and 3.5 sites, as | [

What fonts do you use for programming, and for what language/IDE? I use [Consolas](http://www.microsoft.com/downloads/details.aspx?familyid=22e69ae4-7e40-4807-8a86-b3d36fab68d3&displaylang=en "Consolas") for all my Visual Studio work, any other recommendations?
Either Consolas [(download)](http://www.microsoft.com/downloads/details.aspx?familyid=22e69ae4-7e40-4807-8a86-b3d36fab68d3&displaylang=en) or Andale Mono [(download)](http://prdownloads.sourceforge.net/corefonts/andale32.exe?download). I mostly use Andale Mono. I wrote an article about programming fonts [a long time ago](http://www.deadprogrammer.com/the-programmers-font), I think Consolas wasn't even out yet.

We've been having some issues with a SharePoint instance in a test
environment. Thankfully this is not production ;) The problems started
when the disk with the SQL Server databases and search index ran out
of space. Following this, the search service would not run and search
settings in the SSP were not accessible. Reclaiming the disk space did
not resolve the issue. So rather than restoring the VM, we decided to
try to fix the issue.
We created a new SSP and changed the association of all services to
the new SSP. The old SSP and it's databases were then deleted. Search
results for PDF files are no | [

My dream IDE does full code hints, explains and completes PHP, Javascript, HTML and CSS. I know it exists!
so far, [Zend studio 6](http://www.zend.com/en/products/studio/features), under the Eclipse IDE does a great job at hinting PHP, some Javascript and HTML, any way I can expand this?
edit: a bit more information: right now, using zend-6 under eclipse, i type in
```
<?php
p //(a single letter "p")
```
and I get a hint tooltip with all the available php functions that begin with "p" (phpinfo(), parse\_ini\_file(), parse\_str(), etc...), each with its own explanation: phpinfo()->"outputs lots of PHP information", the same applies for regular HTML (no explanations however).

I'd love it if I could get, from that "b" suggestions for "border", "bottom", etc. The same applies for Javascript.
Any ideas?
I think the JavaScript and CSS need to be in separate files for this to work.

What's really going on here? I know nothing about the compilers/bytecode interpreters for java...
In the first case, you have a widening conversion happening. This can be see when runinng the "javap" utility program (included w/ the JDK), on the compiled class:
```
public static void main(java.lang.String[]);

```
Clearly, you see the I2L, which is the mnemonic for the widening Integer-To-Long bytecode instruction. See reference [here](http://java.sun.com/docs/books/jvms/second_edition/html/Instructions2.doc6.html).
And in the other case, replacing the "long x" with the object "Long x" signature, you'll have this code in the main method:
```
public static void main(java.lang.String[]);
Code:
0: iconst_ 5
1: istore_ 1

doing:
* Set up two branches -- the release and development branch.
* For the development branch, include a post-commit hook that deploys the repository to the dev server, so you can test.
* Once you're ready, you merge your changes into the release branch. I'd also suggest putting in a post-commit hook for deployment there.
You can also set up individual development servers for each of the team members, on their workstations. I find that it speeds things up a bit, although you do have some more setup time.

I am looking for a way to prompt the user to Open / Save As on a local file stored in the Application Storage Directory. I have tried using the FileReference + URLRequest classes but this throws an exception that it needs a remote url.
My last resort is just copying the file to their desktop : \

I've played with CVS a little bit and am not the most familiar with all of its capabilities, but a huge annoyance for me is trying to add new directories that contain more directories in them. Running "`cvs add`" only adds the contents of the current directory, and using "`cvs import`" didn't look like the right thing either since it's still all code I'm producing (this howto claimed import is for [3rd party sources](http://www.thathost.com/wincvs-howto/cvsdoc/cvs_16.html#SEC136))

Char's are great because they are fixed size and thus make for a faster table. They are however limited to 255 characters. I want to hold 500 characters but a blob is variable length and that's not what I want.
Is there some way to have a fixed length field of 500 characters in MySQL or am I going to have to use 2 char fields?
I would suggest using a varchar(500). Even though varchar isn't a fixed length, the database should reserve the correct amount of space. You shouldn't notice any performance difference using varchar(500) over 2xchar(255).

My company is in the process of starting down the **Grails** path. The reason for that is that the current developers are heavy on **Java** but felt the need for a **MVC-style language** for some future web development projects. Personally, I'm coming from the design/usability world, but as I take more "front-end" responsibilities I'm starting to feel the need for learning a language more intensively so I can code some logic but especially the front-end code for my UIs and stuff.
I've been trying to get into **Python/Django** personally, but just never invested too much time on it. Now that my | [

* Should I be learning RoR, and have a more versatile language in my "portfolio", knowing that my RoR knowledge will be useful for my Grails needs as well??

* Should I just skip RoR and focus on learning Grails that I'll be needing for work soon, and work on learning RoR/Django (Ruby/Python) later?

Language (Groovy and Ruby)
--------------------------
As a language I reckon Ruby is more funky compared to Groovy. Groovy only exists to ease Java programmer as you don't need to learn too much new syntax. But overall I reckon is not as funky as Ruby. Groovy wouldn't be the JVM language that is worth to learn based on attender's | [

Community and Job openings
--------------------------
As for the community, Grails community is not as big as Rails, though since the acquirement by Spring more and more people are using it in serious application. Rails has more job openings in the market compared to Grails (that is if you want to invest in looking a new job).

Grails itself is built upon several popular Java framework (Spring & Hibernate). Rails itself IMHO is funky like Ruby itself, but it's funkyness costs you maintainability.

A researcher has created a small simulation in MATLAB and we want to make it accessible to others. My plan is to take the simulation, clean up a few things and turn it into a set of functions. Then I plan to compile it into a C library and use [SWIG](https://en.wikipedia.org/wiki/SWIG) to create a Python wrapper. At that point, I should be able to call the simulation from a small Django application. At least I hope so.
Do I have the right plan? Are there are any serious pitfalls that I'm not aware of at the moment?

I am currently in the process of creating my own blog and I have got to marking up the comments, but what is the best way to mark it up?
The information I need to present is:
1. Persons Name
2. Gravatar Icon
3. Comment Date
4. The Comment
*PS: I'm only interested in semantic HTML markup.*
I think that your version with the cite, blockquote, etc. would definitely work, but if semantics is your main concern then I personally wouldn't use cite and blockquote as they have specific things that they are supposed to represent.
The blockquote tag is meant to represent a quotation taken from another | [

I think an argument can certainly made that you can use semantic HTML with class names, provided they are meaningful. This article on Plain Old Semantic HTML makes a reference to using class names - <http://www.fooclass.com/plain_old_semantic_html> | [

In C#, (and feel free to answer for other languages), what order does the runtime evaluate a logic statement?
Example:
```
DataTable myDt = new DataTable();
if (myDt != null && myDt.Rows.Count > 0)
{
//do some stuff with myDt
}
```
Which statement does the runtime evaluate first -
```
myDt != null
```
or:
```
myDt.Rows.Count > 0
```
?
Is there a time when the compiler would ever evaluate the statement backwards? Perhaps when an "OR" operator is involved?
---
> & is known as a logical bitwise operator and will always evaluate all the sub-expressions
What is a good example of when to use the bitwise operator instead of the "short-circuited boolean"?

I'm currently evaluating the `MSF for CMMI` process template under **TFS** for use on my development team, and I'm having trouble understanding the need for separate bug and change request work item types.
I understand that it is beneficial to be able to differentiate between bugs (errors) and change requests (changing requirements) when generating reports.
In our current system, however, we only have a single type of change request and just use a field to indicate whether it is a bug, requirement change, etc (this field can be used to build report queries).
What are the benefits of having a separate workflow for | [

bugs?
I'm also confused by the fact that developers can submit work against a bug **or** a change request, I thought the intended workflow was for bugs to generate change requests which are what the developer references when making changes.
@Luke
I don't disagree with you, but this difference is typically the explanation given for why there is two different processes available for handling the two types of issues.
I'd say that if the color of the home page was originally designed to be red, and for some reason it is blue, that's easily a quick fix and doesn't need to involve many people | [

or man-hours to do the change. Just check out the file, change the color, check it back in and update the bug.
However, if the color of the home page was designed to be red, and is red, but someone thinks it needs to be blue, that is, to me anyway, a different type of change. For instance, have someone thought about the impact this might have on other parts of the page, like images and logos overlaying the blue background? Could there be borders of things that looks bad? Link underlining is blue, will that show up?

am red/green color blind, changing the color of something is, for me, not something I take lightly. There are enough webpages on the web that gives me problems. Just to make a point that even the most trivial change can be nontrivial if you consider everything.
The actual end implementation change is probably much of the same, but to me a change request **is** a different beast, precisely because it needs to be thought about more to make sure it will work as expected.
A bug, however, is that someone said **this is how we're going to do it** and then someone | [

did it differently.
A change request is more like **but we need to consider this other thing as well... hmm...**.
There are exceptions of course, but let me take your examples apart.
If the server was *designed* to handle more than 300,000,000,000 pageviews, then yes, it is a bug that it doesn't. But designing a server to handle that many pageviews is more than just saying *our server should handle 300,000,000,000 pageviews*, it should contain a **very** detailed specification for how it can do that, right down to processing time guarantees and disk access average times.

as designed, and unable to perform as expected, then the question becomes: *did we design it incorrectly or did we implement it incorrectly?*.
I agree that in this case, wether it is to be considered a design flaw or a implementation flaw depends on the actual reason for why it fails to live up to expectations. For instance, if someone assumed disks were 100x times as fast as they actually are, and this is deemed to be the reason for why the server fails to perform as expected, I'd say this is a design bug, and someone needs to redesign.

the original requirement of that many pageviews is still to be held, a major redesign with more in-memory data and similar might have to be undertaken.
However, if someone has just failed to take into account how raid disks operate and how to correctly benefit from striped media, that's a bug and might not need that big of a change to fix.
Again, there will of course be exceptions.
In any case, the original difference I stated is the one I have found to be true in most cases. | [
