- 1st by checking the data posted from the form if they match with
those that are in a table 'admin' in database. so I have to create a table in my db and add one user only admin and then check with an sql query the match
- or 2nd by making a script like this:

I know that the 2nd microphone is intended for helping noise cancellation and this is a great feature. I am wondering whether the Nexus One is the only such Android phone. | 2 |

on a simple sample server app i have the following code:
procedure TForm13.ServerSocket1ClientRead(Sender: TObject;
Socket: TCustomWinSocket);
var str : string;
begin
str := socket.ReceiveText;
showmessage(str);
end;
and on the client side i have
clientsocket1.Open;
clientsocket1.Socket.SendText(txtMSG.Text);
nothing fancy.
the strange thing is that when i send a message to the server for 1st time it gets ignored. every time after that it works great. the ClientRead event doesn't fire off at all on the 1st message
what can i change on the server to make it accept the 1st message.
I have no control over the client side as a 3rd party sends me messages, ut i am always missing the 1st message.

I have a form on page1.php which redirects to page2.php, I want to pass the data from the form to page3.php immediately on load of page2.php. (the user doesn't need to see what's going on in page3, only page2)
What should I use to pass the variables? Currently I'm using

Most of the blog posts that I write are tutorials / how-tos. So it doesn't make sense to organize on based of date.
I would like to know your comments / suggestions on how do you organize your urls in wordpress. I know wordpress does not recommended permalink based on category name: /category/postname, but I would like to organize urls based on categories without affecting blob performance.

I've had one query running "forever" (more than 2 days, until I killed the session), which was using a database link.
Problem seemed to be that the remote database became unavailable and for some yet unkown reason no `ORA-02068` was raised (not to be discussed here) and the query just waited and waited.
I've simulated this situation by putting one of my test DBs in quiesce mode and queried it over a database link. As anticipated, the query was waiting until either manually cancelled or the remote DB was unquiesced.
**Question:**
I have no control over the remote database's behaviour and uptime, so I am in search for some possibility to set a timeout on a query which is using a database link.
I've already looked into profiles (`CPU_PER_CALL` etc) and `sqlnet.ora` parameters, but they either work for busy or idle sessions, but not for sessions in wait.
So I am in search for some option on the "local" side of the database link, which kind of sets a timeout for queries over database links.
Some solution like `alter session set xyz` or `select ... from a@b "wait 100" --(yes, I know this syntax doesn't exist)` would be appreciated, as I have no DBA rights on these particular DBs.
I'm currently on 10gR2 but upgrading to 11gR2 in a few weeks, so ideas for any of these versions will be useful. | oracle | oracle10g | timeout | oracle11g | null | 07/26/2012 12:40:44 | off topic | Is there a timeout for a query over database link?

I do have a line chart control named `mcChart` in which i have bound the item source to `Date` and `Amount` properties of class `customer`.
public class Customer
{
public DateTime Date{ get; set; }
public int Amount{ get; set; }
}
I do have this method through WCF ria domain service class to access the sql table `gardenwater{Id, Date, Amt}`:
public IQueryable<gardenwater> GetGardenwaters()
{
return this.ObjectContext.gardenwaters;
}
Now i want to store the data in `List<Customer> cust = new List<Customer>();` so that it can be shown in the chart.
I have tried like this :
EntityQuery<gardenwater> inquery = from c in wdc.GetGardenwatersQuery()
select new { Date =Convert.ToDateTime(c.Date), Amount =Convert.ToInt32(c.usedwater) };
and then
foreach (var gardenWater in inquery )
{
cust.Add(new Customer() { Date = Convert.ToDateTime(gardenWater.Date), Amount = Convert.ToInt32(gardenWater.usedwater) });
}
mcChart.DataContext = cust;
Doing all the above i am not able to get any good results.

Also it should be distributed because I have gigs of logs everyday and no single machine will be able to store logs.
I'm particularly interested in something that will work with Ruby and will work on Windows and latest Solaris (yeah, I got a zoo).
I see architecture as:
- Log crawler (Ruby script).
- Distributed log storage.
- Distributed search engine.
- Lightweight front end.
Log crawler and distributed search engine are out of questions - logs will be parsed by Ruby script and ElasticSearch will be used to index log messages. Front end is also very easy to choose - Sinatra.
My main problem is distributed log storage. I looked at MongoDB, CouchDB, HDFS, Cassandra and HBase.
- MongoDB was rejected because it doesn't work on Solaris.
- CouchDB doesn't support sharding (smartproxy is required to make it work but this is something I don't want to even try).
- Cassandra works great but it's just a disk space hog and it requires running autobalance everyday to spread the load between Cassandra nodes.
- HDFS looked promising but FileSystem API is Java only and JRuby was a pain.
- HBase looked like a best solution around but deploying it and monitoring is just a disaster - in order to start HBase I need to start HDFS first, check that it started without problems, then start HBase and check it also, and then start REST service and also check it.
So I'm stuck. Something tells me HDFS or HBase are the best thing to use as a log storage, but HDFS only works smoothly with Java and HBase is just a deploying/monitoring nightmare.
Can anyone share its thoughts or experience building similar systems using components I described above or with something completely different? | logging | hbase | hdfs | splunk | null | null | open | What is the best components stack for building distributed log aggregator (like Splunk)?

I just want know why it is happening .Is that it create problem in future .And How can i solve
I am using this code please check it out And suggest me best way to solve this.
//start tracking vehicle locations. In DEMO mode just read locations from the path...
- (void) start
{
[self performSelectorInBackground:@selector(startTracking) withObject:nil];
}
- (void) stop
{
[NSObject cancelPreviousPerformRequestsWithTarget:self];
self.isMoving = NO;
}
- (void) startTracking
{
self.isMoving = YES;
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
for(int i=_currentPathPointIndex+1; i<path.pointCount; i++)
{
currentLocation = self.path.points[i];
_distanceTravelled += MKMetersBetweenMapPoints(self.path.points[i], self.path.points[i-1]);
//send notification
[[NSNotificationCenter defaultCenter] postNotificationName:kObjectMovedNotification object:self];
[NSThread sleepForTimeInterval : DEMO_SPEED];
}
//finished moving along the path - send notification
[[NSNotificationCenter defaultCenter] postNotificationName:kObjectRechedEndOfPathNotification object:self];
[pool drain];
}

Hi all,
How do I reference an instance of a custom class inside a custom function defined within the class?
I've extended a class through ExtJS4's class extension "mechanism", and I've a custom event handler that will be called when something is triggered, and I want to collapse the Panel when something is fired.
However, in the event handler of the Reactor class below, "this" references EventTriggerer (The firer of the event) instead of the instance of the Reactor. How do I reference the instance of the EventReactor inside a custom function?
Thanks!
DashK
Ext.define('EventReactor', {
extend: 'Ext.panel.Panel',
onSomething: function(data) {
// ERROR
// this.collapse is undefined. "this" actually references EventTriggerer
this.collapse();
}
});
Ext.define('EventTriggerer', {
extend: 'Ext.util.Observable',
singleton: true,
constructor: function() {
this.addEvents({
"changedView" : true
});
},
doSomething: function() {
// Do some stuff
this.fireEvent("doneSomething", data);
}
});
...
// Here's how the listeners are added
var er = Ext.create('EventReactor');
EventTriggerer.addListener("doneSomething", er.onSomething);
// Here's how the event is triggered.
ef.doSomething();

I had problem to do this with default WebBrowser becouse the trick(found on stackoverflow) worked only for 1 page and dont for all session.
Olso i need JavaScript support.
My Question is :
Is there another webBroswer that emulate multiple "tabs" of webBrowser , support javaScript (This is very important : i need disable Javascript for a website page that have Location Header ), and that it's possible change UserAgent and so emulate all existing Browsers ?
If answer it's not What kind of "real" browser could i use with My c# WinForm Program?

I'm taking an unusual approach: **even though I know there are some language features they haven't covered yet that would help me, I am trying to do these exercises using *only* things they have explicitly covered.** Why? Just kind of for fun really. It feels like it is forcing me to give my brain some extra practice with recursion.
So I just completed the exercise posed as follows: **"Create a function that sorts a list of lists based on the length of each sublist. (You may want to look at the sortBy function from the Data.List module.)"**
Now, they threw in the hint about the Data.List module. But they didn't say a word about where reference doc can be found, about how to import stuff, etc. So I decided to *roll my own sort* just to see if I could do it. I used Bubble Sort since it's the simplest algorithm.
The result is below. I'd like to get you Haskell gurus to critique it please ... but **with the following caveat in mind:** *If you suggest improvements, please base them on language features covered through chapter 3 of Real World Haskell (or what you guess those features might be without going to the trouble of looking it up). I **know** there are tons of awesome language features waiting for me that will let me make this code better, but right now the specific challenge was to do it with the "primitive" features covered so far.*
I'm sure there are cases where I'm reaching around my shoulder to scratch my elbow, cases where I'm using explicit control flow when recursion and pattern matching could do more for me, etc. I'm sure the code could be made much shorter and more readable too. I bet there are good idioms I don't know about that can be used with the primitive language features I'm limiting myself to. Those are the kinds of tips I'd love to receive.
This is probably the ugliest code I'm proud of in any language (at least, that I can remember). My first stab, in a functional language, at something beyond "Hello, world" type stuff. And now you are going to beat the crap out of it :) . Be gentle, please, but I'm looking forward to some meaty insight. Thanks.

I'd like to get you Haskell gurus to critique it please ... but **with the following caveat in mind:** *If you suggest improvements, please base them on language features covered through chapter 3 of Real World Haskell (or what you guess those features might be without going to the trouble of looking it up). I **know** there are tons of awesome language features waiting for me that will let me make this code better, but right now the specific challenge was to do it with the "primitive" features covered so far.*
I'm sure there are cases where I'm reaching around my shoulder to scratch my elbow, cases where I'm using explicit control flow when recursion and pattern matching could do more for me, etc. I'm sure the code could be made much shorter and more readable too. I bet there are good idioms I don't know about that can be used with the primitive language features I'm limiting myself to. Those are the kinds of tips I'd love to receive.
This is probably the ugliest code I'm proud of in any language (at least, that I can remember). My first stab, in a functional language, at something beyond "Hello, world" type stuff. And now you are going to beat the crap out of it :) . Be gentle, please, but I'm looking forward to some meaty insight. Thanks.

I'm trying to use MVVM to create a wizard, but I was having trouble figuring out how to control the flow from one page to the next. In some cases I might want a certain step to appear, in others, it doesn't apply.
Anyway, my issue is that I'm using an IEnumerable to return each subsequent page, which works really great, but I know I'm probably doing something improper/unintended with the language. The child class only has to override the abstract Steps IEnumerable accessor:
public class HPLDTWizardViewModel : WizardBase
{
protected override IEnumerable<WizardStep> Steps
{
get
{
WizardStep currentStep;
// 1.a start with assay selection
currentStep = new AssaySelectionViewModel();
yield return currentStep;
// 1.b return the selected assay.
SigaDataSet.Assay assay = ((AssaySelectionViewModel)currentStep).SelectedAssay;
sigaDataSet = (SigaDataSet)assay.Table.DataSet;
// 2.a get the number of plates
currentStep = new NumPlatesViewModel(sigaDataSet);
yield return currentStep;
...
}
}
}
The parent class contains the navigation logic using the Steps attributes' enumerator:
public abstract class WizardBase : ViewModelBase
{
protected abstract IEnumerable<WizardStep> Steps { get;}
public WizardStep CurrentStep
{
get
{
if (_currentStepEnumerator == null)
{
_currentStepEnumerator = Steps.GetEnumerator();
_currentStepEnumerator.MoveNext();
}
return _currentStepEnumerator.Current;
}
}
bool CanMoveToNextPage()
{
if (CurrentStep == null)
return false;
else
return CurrentStep.IsValid();
}
void MoveToNextPage ()
{
_currentStepEnumerator.MoveNext();
if (_currentStepEnumerator.Current == null)
OnRequestClose();
else
OnPropertyChanged("CurrentStep");
}
}
As I said, this works wonderfully because I navigate the list with the Enumerator. Navigation logic is in an abstract parent class and all the child has to do is to override the Steps attribute. The WizardSteps themselves contain logic so that they know when they are valid and the user can continue. I'm using MVVM so the next button is bound to the CanMoveToNextPage() and MoveToNextPage() functions through a Command.
I guess my question is: **how wrong is it to abuse the enumeration model in this case? Is there a better way?** I really need to define the control flow somehow, and it just fit really well with the yield return ability so that I can have flow logic return to the Steps accessor for then next page. | c# | .net | ienumerable | null | null | null | open | Wizard navigation with IEnumerable / yield return

1) ret = write( fd_out, local_bugger, bytes_to_move);
2) nwritten = write (fd, buf + total_written, size - total_written);
Obviously, not the naming conventions.
Specifically, one is writing over the network 4x faster than the other.
Looking for logic , flags, etc

The canvas also contains a grid which i have created by creating lines.
Now for zooming, i remove everything from the canvas, resize the canvas (which is placed inside ScrollViewer), and redraw everything that is on it. Is there a better way to implement zoom, something that is provided, which allows me to scroll and zoom, and somehow create a viewport, that i can move and resize (for scrolling and zooming)? Because my concern is that soon there will be complex shapes, curves and points placed on the canvas, and maybe by the thousands, and things will get pretty slow if i use the approach that i am using currently.
Please tell if there is a better way. | c# | .net | wpf | null | null | null | open | Canvas zoom in and zoom out, is there a better way to implement it?

I have read books on programming, different types software development approaches like waterfall. UML concepts such as class diagrams.
But, I'm always lacking in the design side. I'm looking for a tool or something that will easily aid me in designing software.
For example, when I'm trying to build a game from scratch.
I have a player class, that can shoot and interact. The player class has a super class which is a character. But two days later, I realize I need to add a subclass. I keep having to add functions, classes here and there. It's like i'm writing, rewriting class diagrams and sequence diagrams to the point where it's slowing me down a lot. And when I do start coding, I have to modify the class diagrams yet again. I don't think I'm using the right approach.
Is pencil and paper method any better?
Is there an easier way to approach classes, interaction, sequences?
