• How do I use a MySQL subquery to count the number of rows in a foreign table?

  - by James Skidmore

  I have two tables, users and reports. Each user has no, one, or multiple reports associated with it, and the reports table has a user_id field. I have the following query, and I need to add to each row a count of how many reports the user has: SELECT * FROM users LIMIT 1, 10 Do I need to use a subquery, and if so, how can I use it efficently? The reports table has thousands and thousands of rows.

• Bubbling up events . .

  - by oo

  I have multiple layers in an application and i find myself having to bubble up events to the GUI layer for doing status bar changes, etc . . I find myself having to write repeated coded where each layer simply subscribes to events from the lower layer and then in the call back simply raise an event up the chain. Is there a more efficient way of doing this?

• Can I use WCF to replace my current Web Service and Window Service combination?

  - by gun_shy

  I need a little bit of advise regarding the situation I am faced with. The current arrangement I have been tasked with improving just doesn't sit well with me and I feel like there is a better way to do it. The more I read about WCF, the more I get the feeling that it might be what I am looking for. Right now, I have an asp.net client, a .net web service, a windows service, a ms sql database, and a third party application that is used for processing a group of 'project' files into a finalized file. Since the third party application can only handle processing one 'project' at a time, the combination of the web service, window service, and database have been arranged to create a job queue manager for the third party application. The client sends a zip 'project' file containing multiple sub files to the web service. The web service adds a new 'project' line to the database, generating a unique job id. The zip file is expanded to a folder location on the server using the job id as the folder name. The web service then returns the job id to the client. The client will use this id to poll the web service for the status of the job submitted. When the job is complete, the client will request the processed file. The windows service polls the database every x minutes. If a new job exists, the service will pull the oldest job and send it to the third party app for processing. If the processing succeeds, the window service updates the project line in the database, marking the job complete. The window service will continue to process any non complete jobs in the database until there are no more. When it stops finding any jobs, it will sleep x minutes and then poll the database again. I do not like the fact that the window service has to poll the database. If there is only one job submitted, the client will have to wait for the window service to poll and then wait while the 'project' is being processed. It seems like WCF could be used to combine the web and window services using a combination of the InstanceContextMode.Single and ConcurrencyMode.Multiple. So far, I have been unable to find any articles or examples that would point me in the right direction. Can WCF be utilized to accomplish the job queue logic of the current arrangement in a better way? As always, any help is more than appreciated.

• Is it possible for select lists in HTML to have a horizontal scrollbar?

  - by Alessandro Vernet

  If you have an HTML <select multiple> of a certain width and height (set in CSS), if there are more values then you can possibly fit in that height, then the browser adds a vertical scroll bar. Now if the text is longer than the available width, is it possible to instruct the browser to add a horizontal scrollbar?

• Fast inter-process (inter-threaded) communications IPC on large multi-cpu system.

  - by IPC

  What would be the fastest portable bi-directional communication mechanism for inter-process communication where threads from one application need to communicate to multiple threads in another application on the same computer, and the communicating threads can be on different physical CPUs). I assume that it would involve a shared memory and a circular buffer and shared synchronization mechanisms. But shared mutexes are very expensive (and there are limited number of them too) to synchronize when threads are running on different physical CPUs.

• Is or Are to prefix boolean values

  - by Brian T

  When naming a boolean, or a function returning a boolean it's usual to prefix with 'is' e.g. isPointerNull isShapeSquare What about when refering to multiple items, should it be: arePointersNull or isPointersNull areShapesNull or isShapesNull I can see arguments for both; is offers consistency and perhaps slightly better readability, are makes the code read in a more natural way. Any opinions?

• Is it possible to determine whose code (according to `git blame`) was affected by each hunk output by `git diff`?

  - by Ben

  I have a large cross-cutting commit that I would like to split up according to the authors whose code was affected, both to increase the reviewers' familiarity with the code they're reviewing, and to divide the review burden equitably. I realize that the blame may be mixed within a given hunk, in which case it would be nice to either collect multiple reviewers or just choose the most "blameworthy" one (breaking ties arbitrarily is fine).

• JPA and compatibility with persistance providers and databases vendors

  - by Kartoch

  JPA promises to be vendor neutral for persistence and database. But I already know than some persistence frameworks like hibernate are not perfect (character encoding, null comparison) and you need to adapt your schema for each database. Because there is two layers (the persistence framework and database), I would imagine they're some work to use some JPA codes... Does anyone has some experiences with multiple support and if yes, what are the tricks and recommendations to avoid such incompatibilities ?

• ORDERING A MYSQL QUERY WITH JOINS AND GROUPS

  - by Oliver

  I have this mysql query: SELECT * FROM Customer c JOIN eHRDemographic ehD ON ehD.CxID = c.CustomerID JOIN CustPrimaryWeight cpW ON cpW.CxID = c.CustomerID WHERE c.CustomerID =22703 GROUP BY c.CustomerID ORDER BY cpW.CustPrimaryWeightID DESC This doesn't really work correctly as the CustPrimaryWeight table has multiple enteries and it's simply joining the first entry and not the more recent one as the ORDER statement doesn't seem to do anything. Any ideas?
