The script works, but in my opinion, it's clumsy and probably non-efficient. The script is also inherited code, which I have modified a little to make it more readable. Still, it's a mess.
At the moment, the script reads the datafile(~4Mb) and puts it into array. Then it loops through array parsing its content and pushing values to another array and finally printing them to file in another for loop. If value is not found for certain point, then it prints 9999. Zero is an acceptable value.
The datafile has 5 different parameters and each of them is written to its own file.
Example of data:
data for the param: 2
5559
// (x,y) count values
280 40 3 0 0 0
280 41 4 0 0 0 0
280 42 5 0 0 0 0 0
281 43 4 0 0 10 10

40 51 8 0 0 0 0 0 0 0 0
...
data for the param: 3
3356
// (x,y) count values
**5559** is the number of data lines to current parameter. Data line goes: **x**, **y**, **number of consecutive values** for that particular point and finally the **values**.
There is an empty line between parameters.
As I said earlier, the script works, but I feel like this could be done so much easier and more efficiently. I just don't know how. So here's a chance for self-improvement.
What would be better approach to this problem, than a complicated combo of arrays and for-loops? | perl | grid | self-improvement | null | null | null | open | How to fill N x M grid efficiently with Perl?

I am relatively new to full OO programming but I need advise on the following.
I have one data type (table) which then needs to pull in lots of information from other tables to construct a full record.
For example:
I have a item called "Building". Each building has one "manager" and a collection of "floors". So far I am creating a new class which contains all these objects. See below:
public BuildingComplete
{
public building _building;
public manager _manager;
public IEnumerable<floors> _floors;
public BuildingComplete()
{}
}
I'm then declaring this object and defining all the elements outside the class. This seems rather messy. Ideally I'd like to create a "building" object and within that object it will go away and create all the necessary elements within it. It can do this because the "Building" object contains all the linking id's / information to query the other data tables.
I looked at creating a child of "Building" but I don't know how to set the base: "Building" from the Child.....or even if this is the right thing to do.
Any ideas / pointers will be gratefully received.

x_coord = *x_coord1*
*pause 30ms*
x_coord = *x_coord2*
*pause 9ms*
x_coord = *x_coord2*
*pause 13ms*
...
for instance:
x_coord = 700
*pause 30ms*
x_coord = 711
*pause 9ms*
x_coord = 708
*pause 13ms*
...
x_coord is declared as
private int x_coord;
so it is available even to threads.
This is a x-Coordinate for a mouse pointer. The differring pause times and values make it not move smoothly.
I thought about using a thread like this:
void threadname()
{
//What
Thread.Sleep(17); // 1/60Hz = 0,0166666666666667
}
The question is, how to fill //What?
So while threadname is running, it should smooth the values, ie keep the time between values constant at 17ms and while being in between real values predict the coming next value and create a value that might be in between. Normally the curve is a sine curve, so moving to the right, slowing down, moving to the left etc.
So what I am looking for is something like this:
void threadname()
{
//Determine current(ie each 17th ms) probable value of x-coord.
Thread.Sleep(17); // 1/60Hz = 0,0166666666666667

That being, and since I need to filter queued items by different critera, inside a stored procedure I am using
BEGIN TRANSACTION
CREATE TABLE #Temp (ID INT, SOMEFIELD INT)
INSERT INTO #Temp SELECT TOP (@Something) TableA.ID, TableB.SomeField FROM TableA WITH (ROWLOCK, READPAST) INNER JOIN TableB WITH (UPDLOCK, READPAST) WHERE Condition1

(...)
UPDATE TableB SET SomeField = 1 FROM TableB WITH (ROWLOCK, READPAST) WHERE ID IN (SELECT ID FROM #Temp)
COMMIT TRANSACTION
I am using `ROWLOCK` in the first table and `UPDLOCK` in the second because, after this select, I am going to update `TableB` only, though I need to make sure that these lines don't get updated in`TableA` by any other concurrent query. Everything goes well until the point where I need to insert an `ORDER BY` clause in any of the `SELECT`s above, so that only very specific IDs get selected (I must really do this). What happens is:
1) Without `ORDER BY`, two concurrent executions execute as desired, returning different and non-overlapping results; however, they don't return the results I want because those precise results were outside the scope of every `SELECT` statement.
2) Using `ORDER BY` and two concurrent executions, only the first one returns results. The second one does not return anything.
I recall seeing on a blog that for these kind of queries with `WITH (ROWLOCK, READPAST)` and `ORDER BY` to work one needs to create indexes on the fields one is using in the ordering. I tried it, but I got the same results. How can I get past this problem?

The application itself was coded initially by a half-insane programmer with questionable credentials using many techniques (including such high-minded concepts as Ajax and N-tier architecture) that he didn't quite 'get'. It of course has no automated tests, no formal spec, no changelog - heck, before I got there they had never even heard of source control. As you can imagine, the application is incredibly difficult to work with, simple changes take days and routinely break unrelated components in unpredictable ways.
Management has thus far refused to give me time to rewrite the application preferring to fight fires. They do however acknowledge the problem and have decreed that the solution lies in outsourcing.
Now I am skeptical of the ability of this approach to result in an improvement in code quality but with no numbers to put behind any alternatives I am willing to give it a try. I would like to press the team to work in an ALT.NET/Agile fashion, short iterations, full unit testing, and a strongly decoupled architecture as I feel like this is the most likely way to get solid work out of the team.
I am wondering if anyone has any experience with a similar project and any advice they might have. Our company has zero outsourcing experience and the research I have done on this is actually quite negative for this type of project and given our restrictions so any ideas or comments in general are more than welcome. | outsourcing | null | null | null | null | 09/23/2011 05:08:44 | off topic | Outsourcing a project that needs an improvement in code quality

Now I wonder if there is a different solution that runs a Linux version of Java but somehow makes access to the .dll files through Wine.
To sum it up graphically:
- **works:** Wine -> Java(win) -> DLL(win)
- **what I'm asking:** Java(linux) -> Wine -> DLL(win)

I have the hope to make the application start like any other Java application and only require an installation of Wine. The already working solution requires a Wine installation *and* a Windows version of Java.

Each HTML page have some controls and every control action triggers a HTTP POST ajax request to the server. When the page loads, it first issues HTTP POST ajax requests to update the control states. Every new page which comes from the server gets reloaded/refreshed(using JS 'setInterval') in every 5 minutes.
The problem is that in the Webview when the page transits to a new page, the previous page Java Script activities still continues and hence the previous page AJAX requests increases the network bandwidth.
Is there a solution to stop the Javascript activities of the previous page in the webview, so that only the current/active page script works.
Preferably the solution should still have cache enabled, I want to avoid bringing in same pages from the server in less than 5 minutes.
Thanks In Advance

I have a class called validation which I would like to use to check all of the data submitted is valid, however I obviously need somewhere to define the rules for each property to be checked. At the moment, I'm using arrays during the construction of a new object. eg:
$this->name = array(
'maxlength' => 10,
'minlength' => 2,
'required' => true,
'value' => $namefromparameter
)
One array for each property.
I would then call a static method from the validation class which would carry out various checks depending on the values defined in each array.
Is there a more efficient way of doing this?
Any advice appreciated.
Thanks.

If AlcoholStatus has all the values (NotRecorded | Drinker | NonDrinker) it returns 7 as the value for the SqlParameter.
I am parsing this parameter for a stored procedure and I prefer if I can parse the value as "1,2,3,". What's the best way of doing this?

One of the things I'm not so sure about is how to implement the GUI for this. It will need to have many different views, and I'd like to perhaps have each view in a different clickable "tab", with one tab in the foreground at a given time and all the others hidden. I'm just not sure how to go about implementing all these tabs.
Would it be better to implement each tab as a different HTML layer and have buttons control which layer shows up on top? Would it be better instead to (re)generate HTML on the fly when the tab buttons are pressed?

This is because I am using the readLine() method, which stops when it finds a line terminator. What I need is a way to read all the characters the client sends into one string.
Here is my code:

How do I know when I should write to the stream? Any indicators I might have missed?
So far my experience with writing and reading concurrently have not been great. Does anyone know if I should lock the DATA_AVAILABLE handler from being invoked while I'm writing on the stream? Or RxTx accepts concurrent read/writes?

Question
There are 128 placyers participating in a tennis tournament. Assume that the "x beats y" relationship is transitive, i.e., for all players A, B and C, if A beats B and B beats C, then A beats C.
What is the least number of matches we need to organize to find the best player? How many matches do you need to find the best and the second best player??
---
Answer
First we consider the problem of finding the best player. Each game eliminates one player and there 128 players, so 127 matches are necessary and also sufficient. >>>> Understood....
To find the second best, we note that the only candidates are the players who are beaten by the player who is eventually determined to be the best - everyone else lost to someone who is not the best. >>>> Understanding (Those who are lost by the best players are the candidates of second best???? rite???)
To find the best player, the order in which we organize the matches is inconsequential - we just pick pairs from the set of candidates and who ever loses is removed from the pool of candidates.
However if we proceed in an arbitrary order, we might start with the best player, who defeats 127 other players and then the players who lost need to play 126 matches amongst themselves to find the second best. >>>>>>>>>>.. confused
We can do much better by organizing the matches as a binary tree - we pair of players arbitrarily who play 64 matches. After these matches we are left with 64 candidates; we pair them off again arbitrarily and they play 32 matches. Proceeding in this fashion, we organize the 127 matches needed to find the best player and the winner who have played only 7 matches. Therefore we can find the second best player by organizing 6 matches between 7 players who lost to the best player, for a total of 134 matches. >>>>>>> confused...... | algorithm | puzzle | null | null | null | 06/05/2011 23:51:35 | not a real question | Question on sorting.. confused!!

Also, as I've only written fairly simple loops I didn't realize that you could make multiple assignments (right word?) like "max/=10, pow10*=10" at the end of the for() statement ... Is there any limit to this? Bad form?

I've a table that I'm trying to update via DataContext.SubmitChanges() and it's failing due to primary key constraints.
I have no control over the table itself (I can't add an actual ID column), so instead I've modified the Linq entity to use 3 columns as a complex key. The inserts are still failing, even though the key data is unique across both the update set and the existing data in the table, and I'm curious to know why. What am I missing that forces Linq to treat these values as non unique?
Note that I am not trying to solve the update problem itself - I've determined that in my situation DataContext.ExecuteCommand() will work just as well. I'm trying to grok where my understanding of Linq (or of my data) is wrong.
The table structure looks like this:
OPRID (char(30))
DATE (DateTime)
PROJECT_ID (char(15))
HOURS (decimal)
The last 3 columns are the complex key.
And here's some sample data, comma delimited:
cschlege, 2009-1-5, 10100, 0.8
cschlege, 2009-1-5, 10088, 1.1
cschlege, 2009-1-5, 10099, 0.8
cschlege, 2009-1-5, 10088, 1.2
The SubmitChanges() consistently fails on the last of those rows, but given a key of DATE, PROJECT_ID, HOURS those rows should be unique. It doesn't fail on the 3rd row, which has a duplication in the HOURS column, but only when it reaches the duplicate PROJECT_ID. If I remove PROJECT_ID from the complex key then the insert fails on the 3rd row, however.
Why is LINQ not treating those rows as uniquely keyed?

SELECT AutoKey, OnHand FROM ONNM(XLOCK) CROSS JOIN OITM(XLOCK)
WHERE ObjectCode IN ('20', '10000048') AND ItemCode = @ItemCode
the key feature being the CROSS JOIN used to include multiple tables in a single query. I confirmed that if an exclusive lock already exists on the OITM row for @ItemCode in another transaction, then this statement doesn't introduce any lock on ONNM until it can acquire both locks. However, in the more complex full test run, SQL profiler returns some conflicting information. I have imported the SQL profiler results into a table and executed the following query:
select rownum, e.name, EventClass, TextData, SPID, ClientProcessID from #pmit t
join sys.trace_events e on t.EventClass = e.trace_event_id
where rownum between 275799 and 546130

My question is, why was it possible (is it normal) for SPID 78 to acquire a lock on OITM (ca73a6396124) (which happens to represent ItemCode FC1 if I recall correctly) even though it could not acquire a lock on ONNM (36fa3e654c8f). Is my assumption that SQL statements get all-or-none locks incorrect? Does it not hold if the holder of the ONNM lock was a shared lock on a different connection within a transaction that contains multiple connections in the other process? (I think SPID 99 is another connection in the same process as SPID 114.)
This seems to be a really complicated problem to decipher; I don't know if there's a better way of going about deadlock avoidance or finding out what happened here. | sql | sql-server | locking | deadlock | null | 06/29/2012 23:52:26 | off topic | All-or-none exclusive lock on 2 SQL tables
===
My simplistic testing suggested that I can acquire an exclusive lock on 2 tables or postpone acquiring the lock on either until both can be acquired at once by using a query like this:
SELECT AutoKey, OnHand FROM ONNM(XLOCK) CROSS JOIN OITM(XLOCK)
WHERE ObjectCode IN ('20', '10000048') AND ItemCode = @ItemCode
the key feature being the CROSS JOIN used to include multiple tables in a single query. I confirmed that if an exclusive lock already exists on the OITM row for @ItemCode in another transaction, then this statement doesn't introduce any lock on ONNM until it can acquire both locks. However, in the more complex full test run, SQL profiler returns some conflicting information. I have imported the SQL profiler results into a table and executed the following query:
select rownum, e.name, EventClass, TextData, SPID, ClientProcessID from #pmit t
join sys.trace_events e on t.EventClass = e.trace_event_id
where rownum between 275799 and 546130
and (TextData LIKE '(ca73a6396124)' or TextData LIKE '(36fa3e654c8f)'
or TextData LIKE '%(XLOCK)%' or TextData LIKE '%DeadLock%')
order by rownum
And these are the results I got back:

Does it not hold if the holder of the ONNM lock was a shared lock on a different connection within a transaction that contains multiple connections in the other process? (I think SPID 99 is another connection in the same process as SPID 114.)
This seems to be a really complicated problem to decipher; I don't know if there's a better way of going about deadlock avoidance or finding out what happened here. | 2 |

I'm trying to wrap my head on a couple of related concepts, basically the Saga-pattern ( http://www.rgoarchitects.com/Files/SOAPatterns/Saga.pdf) in combination with Event-sourcing (A DDD-concept: http://en.wikipedia.org/wiki/Domain-driven_design)
A good post that wraps it together:
http://blog.jonathanoliver.com/2010/09/cqrs-sagas-with-event-sourcing-part-ii-of-ii/
I'm getting to the question in a minute, but I think I have to try to summarize what I understand of it first (which might well be wrong, so please correct if that's the case) since this might well impact why I'm asking the question to begin with:
1. The Saga pattern is a sort of broker that given an action (end-user, automated, etc. essentially anything that is going to change data) divides that action up in business activities and sends each of these activities as messages to a Message Bus which in turn sends it to the respective aggregate roots to be taken care of.
2. These aggregate roots can operate completely autonomously (nice separation of concerns, great scalability, etc. )
3. A Saga-instance itself doesn't contain any business logic, that is contained in the aggregate roots it sends activities to. The only 'logic' contained in the Saga is 'process'-logic, (often implemented as a Statemachine), which determines based on actions received (as well as follow-up events) what to do (i.e: what activities to send)
4. The Saga-patterns implements a kind of distributed transaction pattern. I.e: when one of the aggregate roots (which again work autonomously, without knowing of eachothers existense) fails, the entire action might have to be rolled back.
5. This is implemented by having all aggregate roots, upon completion of their activity report back to the Saga. (In case of success as well as error)
6. In case all aggregate roots return a success, the internal statemachine if the Saga determines what to do next (or decides it's done)
7. In case of failure, the Saga issues to all aggregate roots that took part in the last action a so called Compensation Action, i.e: an action to undo the last action each of the aggregate roots did.
8. This might be simply doing a 'Minus 1 vote' if the action was "plus 1 vote' but it could be more complicated like restoring a blogpost to it's previous version.
9. Event-sourcing (see the blogpost combining the two) aims to externalize saving the results of each of the activities that each of the aggregate roots undertake to a centralized Event Store (the changes are called 'events' in this context)
10. This Event store is the 'single version of the truth' and can be use to replay the state of all entities simply by iterating the events stored (essentially like an event log)
11. Combining the two (i.e: letting aggregate roots use Event-sourcing to outsource saving their changes before reporting back to the Saga) enables lots of nice possibilities, one of which concerns my question...
I felt I needed to get this off of my shoulder, since it's a lot to grasp in one go. Given this context/mindset (again, please correct if wrong)
**the question:** When an aggregate root receives a Compensate Action and it that aggregate root has outsourced it's state-changes using Event-sourcing, wouldn't the Compensate Action in all situations just be a delete of the last event in the Event Store for that given Aggregate Root? (Assuming the persist-implementation allows deletes)
That would make sense to me a lot (and would be another great benefit of this combination) but as I said I might be making these assumptions based on a incorrect/incomplete understanding of these concepts.
I hope this didn't get too long-winded.
Thanks.

However, I am getting interested into Scala's Lift. Therefore, I would like to know your opinion about which kind of web apps are better suited for which of those two frameworks or it is just a matter of taste, which framework to use?
Finally, which of those frameworks do you think will be more used in the future?
I have the feeling that Grails is far from reaching a critical mass and it still remains very obscure (in the past few months I had the opportunity to work with middle size and IT startups working mostly with the JVM stack and only one person knew and used Grails) and I am not even sure if it can become the "RoR" of the Java world (Indeed reports a drop of growth in the last few months even if other frameworks have a positive growing rate). And I love Groovy, it is really easy to learn but I have noticed how slow it can be for some tasks.
On the other hand, Scala seems to be more popular (Tiobe Index) and the fact that Twitter is using it know gave it even more presence in the blogosphere with lots of lovers and haters making buzz. It is famous for being fast and scalable. However, the language seems somewhat hard to understand and learn for lots of developers (so maybe it will never gain mainstream status) and Lift is little known and I have read some reports that it is better suited for small apps (less than 20 domain classes).
By seeing the number of books published Groovy-Grails dominate right now, but many publishers have Scala book on the works, so I think this advantage will not last long.
Finally, we have the problem that both languages and frameworks still have poor IDE support (it is getting better by the day but far away from what Java shops expect to be productive).
I do not want to start a flame wars, but I would be very interested to hear other users' opinions. | grails | lift | null | null | null | 01/26/2012 11:55:12 | not constructive | Grails - Lift: Which framework is better suited for which kind of applications?

I tried editing each item manually but it became too extensive, and I thought I might use Java instead to read and edit the file since the words that need to be edited have the same beginning and ending in each item.
I thought I would start by looping through the word in Q, save it and when I had the logic working I'd find out how to read the text file and do the same thing again. (I am open for suggestions if there is any other way)
Here comes the code I put together so far, It was a long time ago I coded in Java so I basically have no skills right now.
import javax.swing.JOptionPane;
public class CustomizedList
{
public static void main (String[] args)
{
String Ord = JOptionPane.showInputDialog("Enter a word");
String resultatOrd ="";
for(int i = 0; i < Ord.length(); i++)
{
if(Ord.charAt(i) == 'y' && Ord.charAt(i) == 'e' && Ord.charAt(i) ==
's')
{
resultatOrd += Ord.charAt(i);
System.out.println(resultatOrd);
}
else
System.out.println("Wrong word.");
}
}
}
I am not sure what I am doing wrong, but the word i input doesnt work logically.
There are two words I want to delete from this textfile: YES and NO, both in lower and uppercase.

I want to create an exact replica of the iPhone Safari, just for my iPod; I have jailbroken it and I selected to hide the normal Safari icon.
Now I want to create a website with the exact same icon as safari and save it to my home screen and name in Safari (This is not the problem).
I want this so when a thief uses my iPod, he clicks on the Safari logo because he thinks it's Safari and just browses the web.
But what I want to happen is that every time he clicks on my Safari, a javascript/PHP (no other stuff I'm a total noob in this) script runs and I get his location sent to me and then he gets redirected to google or something else.
So basically my question is: Can I get a javascript/php code to send me his location and then just go to google or another website?
For the record I went to restrictions and disabled the location feature icon off so he doesn't see it, and I disabled deleting apps, so the webclip thing of the Safari "shortcut" also can't be deleted (i think).
