What is best practice for FTP from a SQL Server stored procedure? |
|sql-server|ftp| |
Personally, I would use a [List][1]<Employee> for creating the list on the backend, and then use [IList][2]<Employee> when you return. When you use interfaces, it gives you the flexability to change the implementation without having to alter who's using your code. If you wanted to stick with an ArrayList, that'd be a non-generic [IList][3].

The easiest way to unit test an object with database access is using transaction scopes.
For example:
[Test]
[ExpectedException(typeof(NotFoundException))]
public void DeleteAttendee() {
using(TransactionScope scope = new TransactionScope()) {
Attendee anAttendee = Attendee.Get(3);
anAttendee.Delete();
anAttendee.Save();
//Try reloading. Instance should have been deleted.
Attendee deletedAttendee = Attendee.Get(3);
}
}
This will revert back the state of the database, basically like a transaction rollback so you can run the test as many times as you want without any sideeffects. We've used this approach successfully in large projects. Our build does take a little long to run (15 minutes), but it is not horrible for having 1800 unit tests. Also, if build time is a concern, you can change the build process to have multiple builds, one for building src, another that fires up afterwards that handles unit tests, code analysis, packaging, etc... |
I apply common sense - this sort of thing is just one of the zillion trade-offs that engineering entails, and has few special characteristics that I can see.
But to be more specific, the overwhelming majority of people doing weird unreadable things in the name of performance are doing them prematurely and without measurement. |
The best way to do something like this would be to return, as you say, a List, preferably using generics, so it would be List`<Employee`>.
Returning a List rather than an ArrayList means that if later you decide to use, say, a LinkedList, you don't have to change any of the code other than where you create the object to begin with (i.e, the call to "new ArrayList())". |
NHibernate and Oracle connect through Windows Authenication |

How do I use Windows Authentication to connect to an Oracle database?
Currently I just use an Oracle Username and password however a requirement is to give the user on install the option of selecting Windows Authentication since we offer the same as SQL. |
I like the CxxTest as well for the same reasons. It's a header file only so no linking required. You aren't stuck with Perl as there is a Python runner as well. I will be reviewing the google library soon. The Boost stuff pulls in too much other baggage. |

Note that map is going to modify your source array as well. So you could either do:
map {s/ //g} @outdata;
and skip the @filtered variable altogether, or if you need to retain the originals,
@filtered = @outdata;
map {s/ //g} @filtered;
Although, in that case, it might be more readable to use foreach:
s/ //g foreach @filtered;

Entity Objects can facilitate cacheing on the application layer. Good luck caching a datareader.

There's an alternative approach to this:
#include <iostream>
#include <fstream>
#include <iterator>
using namespace std;
int main()
{
ifstream iFile("input.txt"); // input.txt has integers, one per line
copy(istream_iterator<int>(iFile), istream_iterator<int>(),
ostream_iterator<int>(cerr, "\n"));
return 0;
} |

Well, AFAIK, all .NET versions (except version 1.x) compile to the same bytecode. In case of C#, all new features are simply syntactic sugar, which get transformed into C# 2.0 constructs when compiling.
The key point where things could go wrong is when you use C# 3.0 or 3.5 specific DLLs. They don't work well with the .NET 2.0 framework, so you can't use those.
I can't really think of a workaround for this, sorry :( |

This is not possible, as you say, from a security stand point. The only way you could simulate it, is by creating a modeless dialog window.
There are many third-party javascript-plugins that you could use to fake this effect so you do not have to write all that code. |
COTS Workshop Registration System |
|cots| |
Does anyone have any experience with any COTS systems for managing workshops and the associated registrations, courses, communications, etc.?
We have a home-built Perl system that is about 8 years old and is currently embedded as an iframe in a SharePoint portal site (externally facing). Needless to say, it isn't integrated into our site well, looks like crap, needs an overhaul, lacks features, etc. It would be nice to find either a product we can install or a service that provides those features.
Thanks! |
You can't unfortunately. The only way is to simulate this with a window.open call. |
Not possible. You can however use a third party javascript library that emulates a popup window, and it will probably look better as well and be less intrusive. |
Don't use the confirm() dialog then... easy to use a custom dialog from prototype/scriptaculous, YUI, jQuery ... there's plenty out there. |
The first thing to came to mind is [Quercus][1] (from the makers of the Resin servlet engine), as Jordi mentioned. It is a Java implementation of the PHP runtime and purportedly allows you to access Java objects directly from your PHP (part of me says "yay, at last").
On the other hand, while I have been itching to try a project this way, I would probably keep the separation between J2EE and PHP unless there was a real reason to integrate on the code-level.
Instead, why don't you try an [SOA][2] approach, where your PHP "front-end" calls into the Struts application over a defined REST or SOAP API (strong vote for REST here) over HTTP.
http://mydomain.com/rest/this-is-a-method-call?parameter1=foo
You can use Struts to build your entire "backend" model, dealing only with business logic and data, and completely ignoring presentation. As you expose the API with these URLs, and you are basically building a REST API (which may come in handy later if you ever need to provide greater access to your backend, perhaps by other client apps).
Your PHP application can be built separately (and rather thinly), calling into the REST API (perhaps using Curl) as if it would call into a database or some native PHP class library.
Anyway, that's what I'd do. But, if you do use Quercus, please post how it went.

git-stash vs. git-branch |

He wanted to restore his working state to a previous point in time without losing his current changes. All of the answers revolved around, in various ways, something like
git branch -m master crap_work
git branch -m previous_master master
How does this compare to `git stash`? I'm a bit confused trying to see what the different use case here when it *seems* like everything `git stash` does is already handled by branching… |

@[Jordi Bunster](http://stackoverflow.com/questions/39651/git-stash-vs-git-branch#39862): Thanks, that clears things up. I guess I'd kind of consider "stashing" to be like a lightweight, nameless, branch. So anything stash can do, branch can as well but with more words. Nice! |
The simple approach is to use an 8x8 integer array. Use 0 for empty squares and assign values for the pieces:
1 white pawns
2 white knights
3 white bishops
4 white rooks
5 white queens
6 white king
Black pieces use negative values
-1 black pawn
-2 black knight
etc
8| -4 -2 -3 -5 -6 -3 -2 -4
7| -1 -1 -1 -1 -1 -1 -1 -1
6| 0 0 0 0 0 0 0 0
5| 0 0 0 0 0 0 0 0
4| 0 0 0 0 0 0 0 0
3| 0 0 0 0 0 0 0 0
2| 1 1 1 1 1 1 1 1
1| 4 2 3 5 6 3 2 4
-------------------------
1 2 3 4 5 6 7 8
Piece moves can be calculated by using the array indexes. For example the white pawns move by increasing the row index by 1, or by 2 if it's the pawn's first move. So the white pawn on [2][1] could move to [3][1] or [4][1].
However this simple 8x8 array representation of has chessboard has several problems. Most notably when you're moving 'sliding' pieces like rooks, bishops and queens you need to constantly be checking the indexes to see if the piece has moved off the board.
Most chessprograms today, especially those that run on a 64 bit CPU, use a bitmapped approach to represent a chessboard and generate moves. x88 is an alternate board model for machines without 64 bit CPUs.

You should always go for readability first. The shape of a system will typically evolve as you develop it, and the real performance bottlenecks will be unexpected. Only when you have the system running and can see real evidence - as provided by a profiler or other such tool - will the best way to optimise be revealed.

An interface is a contract between the implementation and the user of the implementation.
By using an interface, you allow the implementation to change as much as it wants as long as it maintains the contract for the users.
It also allows multiple implementations to use the same interface so that users can reuse code that interacts with the interface. |
In VB.NET
For POST requests:
value = Request.Form("formElementID")
For GET requests:
value = Request.QueryString("formElementID")

You don't say what language you're talking about, but in something .NETish, then it's no more work to return an IList than a List<T> or even an ArrayList, though the mere mention of that obsolete class makes me think you're not talking about .NET. |
@ Jason
You may as well return IList<> because an array actually implements this interface. |

"Premature optimization is the root of all evil." - Donald Knuth |
at times when optimization is necessary, i'd rather sacrifice compactness and keep the performance enhancement. perl obviously has some deep waters to plumb in search of the conciseness/performance ratio, but as cute as it is to write one-liners, the person who comes along to maintain your code (who in my experience, is usually myself 6 months later) might prefer something more in the expanded style, as documented here:

Just to extend the previous answer... If, for whatever reason, the assignments need to be part of the conditional, you'd want to write it thusly:
$condition ? ($a=2) : ($a=3);
This would be useful if you're assigning to different variables based on the condition.
$condition ? ($a=2) : ($b=3);
And if you're choosing the variable, but assigning the same thing no matter what, you could even do this:
($condition ? $a : $b) = 3;
|
I use generic lists for almost all scenarios. The only time that I would consider using a derived collection anymore is if I add collection specific members. However, the advent of LINQ has lessened the need for even that. |
First of all, I am not completely sure I follow, you might need to provide some additional details to help us understand what is happening and what the problem is. I guess I am not sure I understand exactly what you're trying to accomplish and what the problem is.
Second, you shouldn't need to set the dialog's parent since that is essentially what is happening with the call to Create (passing the parent). The dialogs you're describing sound like they could use some "re-thinking" a bit to be honest. Is this dialog to enter the properties of the image a child of the source window, or the WYSIWYG window? |

Static methods are not instance methods. There's no instance context, therefore to implement it from the interface makes little sense. |
I'll answer your question with an example. Suppose we had a Math class with a static method add. You would call this method like so:
Math.add(2, 3);
If Math were an interface instead of a class, it could not have any defined functions. As such, saying something like Math.add(2, 3) makes no sense.
|
I would suggest if you are going for a PHP and MySQL install to instead use [WAMP][1]. It works great and is easy to add extensions and modify everything. I use it for work and love it.
[1]: http://www.wampserver.com/en/ "WAMP" |
The reason why you can't have a static method in an interface lies in the way Java resolves static references. Java will not bother looking for an instance of a class when attempting to execute a static method. This is because static methods are not instance dependent and hence can be executed straight from the class file. Given that all methods in an interface are abstract, the VM would have to look for a particular implementation of the interface in order to find the code behind the static method so that it could be executed. This then contradicts how static method resolution works and would introduce an inconsistency into the language. |

If you application uses the JEE stack and you are using [Hibernate][1] you can use the [Compass Framework][2] maintain a searchable index of your database. The Compass Framework uses [Lucene][3] under the hood.
The only catch is that you cannot replicate your search index. So you need to use a clustered database to hold the index tables or use the newer grid based index storage mechanisms that have been added to the Compass Framework 2.x.

This is specific to a C# project, but I ignore these files/directories:
- *.csproj.user
- /obj/*
- /bin/*
- *.ncb
- *.suo
I have no problems running the code in the depot on other machines after I ignore all of these files. The easiest way to find out what you need to keep is to make a copy of the folder and start deleting things you think aren't necessary. Keep trying to build, and as long as you can build successfully keep on deleting. If you delete too much, copy it from the source folder.
In the end you'll have a nice directory full of the only file that have to be committed. |
I use a CSS class instead:

[.NET 3.5 SP1 tries to use the action="" attribute][1] (.NET 3.5 RTM did not). So, when you deploy, your code is attempting to set the HtmlForm.Action property and failing, as the System.Web.dll on the deploy target is RTM and does not have a setter on the property.

[Frank Krueger][1] writes:
> Gaius: A Null Pointer exception gets thrown for you automatically by the runtime, there is no benefit to testing that stuff in the function prologue.
I have two responses to this:
1. Null was just an example. For square(x), I'd want to test that the square root of the result is (approximately) the value of the parameter. For setters, I'd want to test that the value actually changed. For atomic operations, I'd want to check that all component operations succeeded or all failed (really one test for success and n tests for failure). For factory methods in weakly-typed languages, I want to check that the right kind of object is returned. The list goes on and on. Basically, anything that can be tested in one line of code is a very good candidate for a code contract in a prologue comment.
2. I disagree that you shouldn't test things because they generate runtime exceptions. If anything, you *should* test things that might generate runtime exceptions. I like runtime exceptions because they make the system [fail fast][2], which helps debugging. But the `null` in the example was a result value for some possible input. There's an argument to be made for never returning `null`, but if you're going to, you should test it.

Dynamic robots.txt |

Let's say I have a web site for hosting community generated content that targets a very specific set of users. Now, let's say in the interest of fostering a better community I have an off-topic area where community members can post or talk about anything they want, regardless of the site's main theme.
Now, I _want_ most of the content to get indexed by Google. The notable exception is the off-topic content. Each thread has it's own page, but all the threads are listed in the same folder so I can just exclude search engines from a folder somewhere. It has to be per-page. A traditional robots.txt file would get huge, so how else could I accomplish this? |

I would highly recommend reading the book [PHP In Action][1]. It takes you through abstracting your database connections, templating systems and all the other basics of a web application. If every PHP developer read this book then the language would have a much better reputation.
It also has chapters on refactoring, unit testing and the MVC control pattern.

jQuery: Can you select by CSS rule, not class? |

Given code like this:

I side-stepped this problem completely by building my Qt app statically on MacOSX. That might not be practical for you though. |
Simlarly to @James Marshall's suggestion - in ASP.NET you could use an HttpHandler to redirect calls to robots.txt to a script which generated the content. |
Matthew has the correct approach here. In my opinion, it is very unusual for an application to reset a sequence's current value after every use. Much more conventional to set the increment size to whatever you need upfront.
Also, this way is much more performant. Selecting nextval from a sequence is a highly optimised operation in Oracle, whereas running ddl to alter the sequence is much more expensive.
I guess that doesn't really answer the last point in your edited question... |

I don't think (at least can't find a way to make) [Chris' answer][1] work in this case because ***do_div()*** actually changes the dividend in-place. Getting the absolute value implies a temporary variable whose value will change the way I require but can't be passed out of my ***__divdi3()*** override.
I don't see a way around the parameter-by-value signature of ***__divdi3()*** at this point except to mimic the technique used by ***do_div()***.
It might seem like I'm bending over backwards here and should just come up with an algorithm to do the 64-bit/32-bit division I actually need. The added complication here though is that I have a bunch of numerical code using the '/' operator and would need to go through that code and replace every '/' with my function calls.
I'm getting desperate enough to do just that though.
Thanks for any follow-up,

It is better to use a look-up table for obtaining the distance between two cities.
This makes sense because
* The Formula to calculate the distance ais quite computationally intensive..
* Distance between cities is unlikely to change.
So unless you needs are very specific (like terrain mapping from a satellite or some or topography algorithm or something else), you should really just save the list of cities and distances between them, into a table and look it up as needed. |

You are looking for the DN Attribute, also called "distinguishedName". You can simply use DOMAIN\DN once you have that.
Edit: For groups, the CN (Common Name) could also work.
The full string from Active Directory normally looks like this:
>cn=Username,cn=Users,dc=DomainName,dc=com
(Can be longer or shorter, but the important bit is that the "ou" part is worthless for what you're trying to achieve. |
This is a knapsack problem [(wikipedia to the rescue!)][1] The weights are the days in transit, and the profit should be $5000 - cost of leg. Eliminate all negative costs and go from there!

One option is to use a single subversion repository and check-in changes that effect both library and project at the same time. That way you know that whatever revision of the project you are on requires the same revision of the library. |
Actually, since the size of material is fixed, but the requests are not, it's a bin packing problem.
Again, [wikipedia to the rescue!][1]
(Something I might have to look into for work too, so yay!)

Use the [nant task][1], so you get one single build file.

The GAC can also be used by assemblies that require elevated permissions to perform privileged operations on behalf of less trusted code (e.g. a partial trust ASP.NET application).
For example, say you have a partial trust ASP.NET application which needs to perform a task that would require elevated privileges, i.e. Full Trust. The solution is to put the code that requires elevated privileges into a separate assembly. The assembly is marked with the ***AllowPartiallyTrustedCallers*** attribute and the class that contains the privileged logic is marked with the PermissionSet attribute, something like this: ***[PermissionSet(SecurityAction.Assert, Unrestricted=true)]*.**
Our assembly would be given a strong name (signed) and then deployed into the GAC.
Now our partially trusted app(s) can utilise the trusted assembly in the GAC to carry out a specific and narrow set of privileged operations without losing the benefits of partial trust.
