Does anybody have experience working with PHP accelerators such as [MMCache](http://turck-mmcache.sourceforge.net/) or [Zend Accelerator](http://www.zend.com/en/)? I'd like to know if using either of these makes PHP comparable to *faster* web-technologies. Also, are there trade offs for using these?
Note that Zend Optimizer and MMCache (or similar applications) are totally different things. While Zend Optimizer tries to optimize the program opcode MMCache will cache the scripts in memory and reuse the precompiled code.
I did some benchmarks some time ago and you can find the [results](http://blogs.interdose.com/dominik/2008/04/11/benchmarking-php-eaccelerator-und-andere-opcode-caches/) in my blog (in German though). The basic results:
Zend Optimizer alone didn't help at all. Actually my scripts | [

When it comes to caches:
\* fastest: [eAccelerator](http://eaccelerator.net/)
\* [XCache](http://xcache.lighttpd.net/)
\* [APC](http://www.php.net/manual/en/book.apc.php)
And: You DO want to install a opcode cache!
For example:

This is the duration it took to call the wordpress homepage 10.000 times.

I want to define something like this in *php*:
```
$EL = "\n<br />\n";
```
and then use that variable as an "endline" marker all over my site, like this:
```
echo "Blah blah blah{$EL}";
```
How do I define $EL once (in only 1 file), include it on every page on my site, and *not* have to reference it using the (strangely backwards) `global $EL;` statement in every page function?
Most PHP sites should have a file (I call it a header) that you include on every single page of the site. If you put that first line of code in the header file, then include it like | [

this on every page:
```
include 'header.php';

you won't have to use the global keyword or anything, the second line of code you wrote should work.
Edit: Oh sorry, that won't work inside functions... now I see your problem.
Edit #2: Ok, take my original advice with the header, but use a [define()](http://php.net/define) rather than a variable. Those work inside functions after being included. | [

What's the difference between struct and class in .NET?
In .NET, there are two categories of types, *reference types* and *value types*.
Structs are *value types* and classes are *reference types*.
The general difference is that a *reference type* lives on the heap, and a *value type* lives inline, that is, wherever it is your variable or field is defined.
A variable containing a *value type* contains the entire *value type* value. For a struct, that means that the variable contains the entire struct, with all its fields.
A variable containing a *reference type* contains a pointer, or a *reference* to somewhere else in memory | [

where the actual value resides.
This has one benefit, to begin with:
* *value types* always contains a value
* *reference types* can contain a *null*-reference, meaning that they don't refer to anything at all at the moment
Internally, *reference type*s are implemented as pointers, and knowing that, and knowing how variable assignment works, there are other behavioral patterns:
* copying the contents of a *value type* variable into another variable, copies the entire contents into the new variable, making the two distinct. In other words, after the copy, changes to one won't affect the other
* copying the contents of a *reference type* variable into | [

another variable, copies the reference, which means you now have two references to the same *somewhere else* storage of the actual data. In other words, after the copy, changing the data in one reference will appear to affect the other as well, but only because you're really just looking at the same data both places
When you declare variables or fields, here's how the two types differ:

In php, I often need to map a variable using an array ... but I can not seem to be able to do this in a one liner. c.f. example:
```
// the following results in an error:
echo array('a','b','c')[$key];
// this works, using an unnecessary variable:
$variable = array('a','b','c');
echo $variable[$key];
```
This is a minor problem, but it keeps bugging every once in a while ... I don't like the fact, that I use a variable for nothing ;)
I wouldn't bother about that extra variable, really. If you want, though, you could also remove it from memory after you've used it:
```
$variable = array('a','b','c');
echo $variable[$key];
unset($variable);

I see often (rewritten) URLs without ID in it, like on some wordpress installations. What is the best way of achieve this?
Example: site.com/product/some-product-name/
Maybe to keep an array of page names and IDs in cache, to avoid DB query on every page request?
How to avoid conflicts, and what are other issues on using urls without IDs?
Using an ID presents the same conundrum, really--you're just checking for a different value in your database. The "some-product-name" part of your URL above is also something unique. Some people call them slugs (Wordpress, also permalinks). So instead of querying the database for a row that | [

I was going to say that, I didn't think that Silverlight 2's HttpWebRequest supported streaming, because the request data gets buffered into memory entirely.

With RTL languages like Arabic do users expect the entire interface to be mirrored? For instance should things like OK/Cancel buttons be swapped and on the left?

I understand that these use phonetic input converted to written characters.
> How does that work on the web?
The input is done by a class of software called an [IME (Input Method Editor)](http://en.wikipedia.org/wiki/Input%5Fmethod%5Feditor) on Windows, Mac, and Linux (e.g. SCIM). When an IME is turned on, the input from the keyboard first goes to the IME, and the user gets to pick the correct kanji/hiragana combo. When the user commits by hitting return key, the IME types in the kanji/hiragana into the web browser using the current encoding.

go with an encoding of Unicode. I suggest UTF-8.
> Do the same events fire while inputs and textareas are being edited?
A Unicode savvy web browser and OS combo handles multiple languages. For example, one can use English normal version of Firefox to browse and post to a Japanese website. From the browsers point of view, it's just an array of "bla bla bla" in Unicode. In other words, if the event fires up in English, the same event should fire up in CJKV if you use a Unicode variant.

For the most part you should not have to worry about it, unless you are trapping keyboard events. For example, I hate using Japanese keyboard with bunch of extra keyboard. So, when I have to assign IME on/off command to some key on US keyboard. I personally use right-Alt.

My current development project has two aspects to it. First, there is a public website where external users can submit and update information for various purposes. This information is then saved to a local SQL Server at the colo facility.
The second aspect is an internal application which employees use to manage those same records (conceptually) and provide status updates, approvals, etc. This application is hosted within the corporate firewall with its own local SQL Server database.
The two networks are connected by a hardware VPN solution, which is decent, but obviously not the speediest thing in the world.

that it has to be instant, just reasonably quick.
So far, I have thought about using the following types of approaches:
1. Bi-directional replication
2. Web service interfaces on both sides with code to sync the changes as they are made (in real time).
3. Web service interfaces on both sides with code to asynchronously sync the changes (using a queueing mechanism).
Any advice? Has anyone run into this problem before? Did you come up with a solution that worked well for you?
This is a pretty common integration scenario, I believe. Personally, I think an asynchronous messaging solution using a queue is ideal.

be able to achieve near real time synchronization without the overhead or complexity of something like replication.
Synchronous web services are not ideal because your code will have to be very sophisticated to handle failure scenarios. What happens when one system is restarted while the other continues to publish changes? Does the sending system get timeouts? What does it do with those?

do async messaging using MSMQ bindings, but a tool like nServiceBus or MassTransit will give you a very simple Send/Receive or Pub/Sub API that will make your requirement a very straightforward job.
If you're using Java, there are any number of open source service bus implementations that will make this kind of bi-directional, asynchronous messaging a snap, like Mule or maybe just ActiveMQ.

Everyone remembers google browser sync right? I thought it was great. Unfortunately Google decided not to upgrade the service to Firefox 3.0. Mozilla is developing a replacement for google browser sync which will be a part of the Weave project. I have tried using Weave and found it to be very very slow or totally inoperable. Granted they are in a early development phase right now so I can not really complain.
This specific problem of browser sync got me to thinking though. What do all of you think of Mozilla or someone making a server/client package that we, the | [

users, could run on your 'main' machine? Now you just have to know your own IP or have some way to announce it to your client browsers at work or wherever.
There are several problems I can think of with this: non static IPs, Opening up ports on your local comp etc. It just seems that Mozilla does not want to handle this traffic created by many people syncing their browsers. There is not a way for them to monetize this traffic since all the data uploaded must be encrypted.

to communicate with HTTP servers and can be configured to connect to private servers. I've tried setting it up on my own servers but with no success (Mainly because I'm not very good at working with Apache to configure WebDAV)
I'm hoping Mozilla Weave eventually allows FTP access so I can easily use my server to host my firefox profile.

I've written a stored proc that will do an update if a record exists, otherwise it will do an insert. It looks something like this:
```
update myTable set Col1=@col1, Col2=@col2 where ID=@ID
if @@rowcount = 0
insert into myTable (Col1, Col2) values (@col1, @col2)
```
My logic behind writing it in this way is that the update will perform an implicit select using the where clause and if that returns 0 then the insert will take place.
The alternative to doing it this way would be to do a select and then based on the number of rows returned either do an update or insert. This | [

I considered inefficient because if you are to do an update it will cause 2 selects (the first explicit select call and the second implicit in the where of the update). If the proc were to do an insert then there'd be no difference in efficiency.
Is my logic sound here?
Is this how you would combine an insert and update into a stored proc?
Your assumption is right, this is the optimal way to do it and it's called [upsert/merge](http://en.wikipedia.org/wiki/Upsert).

I wonder if someone knows if there is a pre-made solution for this: I have a List on an ASP.net Website, and I want that the User is able to re-sort the list through Drag and Drop. Additionally, I would love to have a second list to which the user can drag items from the first list onto.
So far, I found two solutions:
* The ReorderList from the [Ajax Control Toolkit](http://www.codeplex.com/AjaxControlToolkit), which requires a bit of manual work to make sure changes [are persisted](http://www.codeproject.com/KB/ajax/PersistentReorderList.aspx) into the database, and that does not support drag/drop between lists.

all I want, but is priced far far beyond my Budget.
Does anyone else have some ideas or at least some keywords/pointers to do further investigation on? Espectially the Drag/Drop between two lists is something I am rather clueless about how to do that in ASP.net.
Target Framework is 3.0 by the way.
The Mootools sortables plugin does just that, and best of all, it's free ;)

Could someone recommend any good resources for creating Graphics User Interfaces, preferably in C/C++?
Currently my biggest influence is [3DBuzz.com](http://www.3dbuzz.com)'s [C++/OpenGL VTMs](http://www.3dbuzz.com/xcart/product.php?productid=30&cat=12&page=1) (Video Training Modules). While they are very good, they cover a large area of graphics programming, so only skim the surface of GUI programming.
This question does relate to "[How do I make a GUI?](https://stackoverflow.com/questions/7489/how-do-i-make-a-gui)", where there is also a rough outline of my current structure.
Any response would be appreciated.

effects that you don't think you would get with a more traditional GUI toolkit (e.g [Qt](http://trolltech.com/), [wxWidgets](http://www.wxwidgets.org/), [GTK](http://www.gtk.org/), etc). If you just need a quick simple GUI for hosting your OpenGL graphics then [FLTK](http://www.fltk.org/) is a nice choice. Otherwise, for rendering the GUI directly in OpenGL their are libraries like [Crazy Eddie's GUI](http://www.cegui.org.uk/wiki/index.php/Main_Page) that do just that and provide lots of [skinnable](http://en.wikipedia.org/wiki/Skinnable) [widgets](http://en.wikipedia.org/wiki/GUI_widget) that you won't have to reinvent.

Is it possible in .NET to list files on a remote location like an URL? Much in the same way the System.IO classes work. All I need is the URLs to images that are on a remote server.
**Short answer:** No, unless you have more control over that web-server
**Long answer:** Here are possible solutions...
1. You will need server-side script that will do it locally and output this list in your preferred format.
2. Most of the web-servers implement default file-browsing pages, so you could theoretically parse those but this solution will be very fragile and not very portable even between different versions | [

I am part of a high school robotics team, and there is some debate about which language to use to program our robot. We are choosing between C (or maybe C++) and LabVIEW. There are pros for each language.
C(++):
* Widely used
* Good preparation for the future (most programming positions require text-based programmers.)
* We can expand upon our C codebase from last year
* Allows us to better understand what our robot is doing.
LabVIEW
* Easier to visualize program flow (blocks and wires, instead of lines of code)
* Easier to teach (Supposedly...)
* "The future of programming is graphical." (Think so?)
* Closer to the | [

of programming?**
* **Is a graphical language easier to learn than a textual language?** I think that they should be about equally challenging to learn.
* Seeing as we are partailly rooted in helping people learn, **how much should we rely on prewritten modules, and how much should we try to write on our own?** ("Good programmers write good code, great programmers copy great code." But isn't it worth being a good programmer, first?)
Thanks for the advice!

I'd like to emphasize this question more:

that C could be taught just as easily, and beginner-level tasks would still be around with C. I'd really like to hear your opinions. **Is there any reason that typing while{} should be any more difficult than creating a "while box?"** **Isn't it just as intuitive that program flows line by line, only modified by ifs and loops, as it is intuitive that the program flows through the wire, only modified by ifs and loops!?**
Thanks again!

of programming, with certain goals. If it's not... I'm sorry...
Before I arrived, our group (PhD scientists, with little programming background) had been trying to implement a LabVIEW application on-and-off for nearly a year. The code was untidy, too complex (front and back-end) and most importantly, did not work. I am a keen programmer but had never used LabVIEW. With a little help from a LabVIEW guru who could help translate the textual progamming paradigms I knew into LabVIEW concepts it was possible to code the app in a week. The point here is that *the basic coding concepts still have | [

to be learnt, the language, even one like LabVIEW, is just a different way of expressing them*.
LabVIEW is great to use for what it was originally designed for. i.e. to take data from DAQ cards and display it on-screen perhaps with some minor manipulations in-between. However, programming *algorithms* is no easier and I would even suggest that it is more difficult. For example, in most procedural languages execution order is generally followed line by line, using pseudo mathematical notation (i.e. `y = x*x + x + 1`) whereas LabVIEW would implement this using a series of VI's which don't necessarily | [

follow from each other (i.e. left-to-right) on the canvas.
Moreover programming as a career is more than knowing the technicalities of coding. Being able to effectively ask for help/search for answers, write readable code and work with legacy code are all key skills which are undeniably more difficult in a graphical language such as LabVIEW.
I believe some aspects of graphical programming may become mainstream - the use of sub-VIs perfectly embodies the 'black-box' principal of programming and is also used in other language abstractions such as [Yahoo Pipes](http://pipes.yahoo.com/pipes/) and the Apple Automator - and perhaps some future graphical language will | [

revolutionise the way we program but LabVIEW itself is not a massive paradigm shift in language design, we still have `while, for, if` flow control, typecasting, event driven programming, even objects. If the future really will be written in LabVIEW, C++ programmer won't have much trouble crossing over.
As a postcript I'd say that C/C++ is more suited to robotics since the students will no doubt have to deal with embedded systems and FPGAs at some point. Low level programming knowledge (bits, registers etc.) would be invaluable for this kind of thing.

I've seen it mentioned in many blogs around the net, but I believe it shoud be discussed here.
What can we do when we have an MVC framework (I am interested in ZEND) in PHP but our host does not provide mod\_rewrite?
Are there any "short-cuts"? Can we transfer control in any way (so that a mapping may occur between pages)? Any ideas?
Thank you :-)
Zend framework should work without `mod_rewrite`. If you can live with your URL:s looking more like "/path/to/app/index.php/controller/action". If you had mod\_rewrite you could do away with the "index.php" bit, but it should work with too.

What are the best resources for Wordpress theme-development? I am currently in the phase of starting my own blog, and don't want to use one of the many free themes. I already have a theme for my website, so I want to read about best-practices.
Any advice on how to get started would be very welcome :)

I'm missing something here:
```
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = New-Object System.DirectoryServices.DirectoryEntry
$objSearcher.Filter = ("(objectclass=computer)")
$computers = $objSearcher.findall()
```
So the question is why do the two following outputs differ?
```
$computers | %{
"Server name in quotes $_.properties.name"
"Server name not in quotes " + $_.properties.name
}
PS> $computers[0] | %{"$_.properties.name"; $_.properties.name}
System.DirectoryServices.SearchResult.properties.name
GORILLA
```
When you included $\_.properties.name in the string, it was returning the type name of the property. When a variable is included in a string and the string is evaluated, it calls the ToString method on that object referenced by the variable (not including the members specified after).

case, the ToString method is returning the **type name**. You can force the evaluation of the variable and members similar to what EBGreen suggested, but by using
```
"Server name in quotes $($_.properties.name)"
```
In the other scenario **PowerShell** is evaluating the variable and members specified first and then adding it to the previous string.
You are right that you are getting back a collection of properties. If you pipe **$computer[0].properties** to get-member, you can explore the object model right from the command line.

So I'm not quite convinced about OpenID yet, and here is why:

StackOverflow account to be associated with my new OpenID?
I understand this would be easy if I had my own domain set up to delegate to a provider, because I could just change the delegation. Assume I do not have my own domain.
Ideally Stack Overflow would allow you to change your OpenID.
OTOH, ideally you would have set up [OpenID delegation](http://wiki.openid.net/Delegation) on your own site, and used that to identify yourself.
With delegation, you would need only change which service you delegate to. You'd still be identified by your own URL that you control. But that doesn't help now unless Stack Overflow lets | [

you change it. Most sites tie OpenIDs to real accounts, and would let you switch or at least add additional OpenIDs. Doesn't seem like you could map OpenIDs to accounts 1:1 unless the result of access is totally trivial; otherwise you're in a situation like this where you lose your existing questions, answers, and reputation for switching IDs. | [

For .net 3.5 SP1, Microsoft have the new client profile which installs only a subset of .net 3.5 SP1 on to Windows XP user's machines.
I'm aware of how to make my assemblies client-profile ready. And I've read the articles on how to implement an installer for [ClickOnce](http://msdn.microsoft.com/en-us/library/cc656916.aspx) or [MSI](http://msdn.microsoft.com/en-us/library/cc656819.aspx).
But I've been using Inno Setup for my project so far and I'd like to continue to use it (as an Express user, I can't easily make MSIs), I need to know how to use the client-profile installer in a custom environment.
There is [an article](http://msdn.microsoft.com/en-us/library/cc656920.aspx) on a Deployment.xml schema, but no indication | [

of how to write one, package it or anything else. Can someone explain this process? Finding the articles I linked to alone was a painful search experience.
Microsoft has now shipped the Client Profile Configuration Designer (Beta).
This designer lets you edit the XML files with some limitations, this isn't a 'Google beta' by any means.

I need some advice as to how I easily can separate test runs for unit tests and integration test in Visual Studio. Often, or always, I structure the solution as presented in the above picture: separate projects for unit tests and integration tests. The unit tests is run very frequently while the integration tests naturally is run when the context is correctly aligned.
My goal is to somehow be able configure which tests (or test folders) to run when I use a keyboard shortcut. The tests should preferably be run by a graphical test runner (ReSharpers). So for | [

example
* Alt+1 runs the tests in project BLL.Test,
* Alt+2 runs the tests in project DAL.Tests,
* Alt+3 runs them both (i.e. all the tests in the [Tests] folder, and
* Alt+4 runs the tests in folder [Tests.Integration].
TestDriven.net have an option of running just the test in the selected folder or project by right-clicking it and select Run Test(s). Being able to do this, but via a keyboard command and with a graphical test runner would be awesome.
Currently I use VS2008, ReSharper 4 and nUnit. But advice for a setup in the general is of course also appreciated.

kind of a solution for this on my own by using keyboard command bound to a macro. The macro was recorded from the menu Tools>Macros>Record TemporaryMacro. While recording I selected my [Tests] folder and ran ReSharpers UnitTest.ContextRun. This resulted in the following macro,
```
Sub TemporaryMacro()
DTE.Windows.Item(Constants.vsWindowKindSolutionExplorer).Activate
DTE.ActiveWindow.Object.GetItem("TestUnitTest\Tests").Select(vsUISelectionType.vsUISelectionTypeSelect)
DTE.ExecuteCommand("ReSharper.UnitTest_ContextRun")
End Sub
```
which was then bound to it's own keyboard command in Tools>Options>Environment>Keyboard.
However, what would be even more awesome is a more general solution where I can configure exactly which projects/folders/classes to run and when. For example by the means of an xml file. This | [

In the past I've never been a fan of using triggers on database tables. To me they always represented some "magic" that was going to happen on the database side, far far away from the control of my application code. I also wanted to limit the amount of work the DB had to do, as it's generally a shared resource and I always assumed triggers could get to be expensive in high load scenarios.
That said, I have found a couple of instances where triggers have made sense to use (at least in my opinion they made sense). Recently though, I | [

found myself in a situation where I sometimes might need to "bypass" the trigger. I felt really guilty about having to look for ways to do this, and I still think that a better database design would alleviate the need for this bypassing. Unfortunately this DB is used by mulitple applications, some of which are maintained by a very uncooperative development team who would scream about schema changes, so I was stuck.
What's the general consesus out there about triggers? Love em? Hate em? Think they serve a purpose in some scenarios?

trigger means that you're "doing it wrong"?
Triggers are generally used incorrectly, introduce bugs and therefore should be avoided. Never design a trigger to do integrity constraint checking that crosses rows in a table (e.g "the average salary by dept cannot exceed X).
[Tom Kyte](http://asktom.oracle.com), VP of Oracle has indicated that he would prefer to [remove triggers as a feature of the Oracle](http://tkyte.blogspot.com/2006/09/classic-example-of-why-i-despise.html) database because of their frequent role in bugs.
