• what's a good way to synchronize a sql server 2008 database from a 2005 database automatically?

  - by Keith Nicholas

  Ok, the scenario is... two servers, on completely different parts of the internet. The sql 2008 database just needs to get data updates and schema changes. It doesn't need to send anything to the 2005 database. Basically just suck data and schema as efficiently as possible automatically as a scheduled task. The database is quite huge.... but the changes per day are probablly around 20/30 megabytes of data/ I can't run any of the inbuilt replication on the 2005 database. I've had a wee look at the Sync Framework, I think that might do what I want, but seems a bit painful and requires a bit of work to get going. I'm wondering if there is tooling out there to make this easier? or?? not quite sure what my options are.

• Background job with status in rails

  - by pepernik

  Hey. I would like to upload a file and then parse it. Because parsing can take up to 10min I installed delayed_job plugin and called parsing function through send_later function. I have to mention that this is an AJAX app. Imagine that you press an AJAX button that starts upload and after that the source is imported into the database. During the process I want to show the progress bar or message (importing...) and when it completes the task status changes to done. My question is: What is the best way to check for status of the process. What would you do? My idea is to have another controller actions "status" which look into the database and provide the right status.

• Checking that all libs and dlls are from the same build?

  - by unknownthreat

  I am developing a program in VS C++ 2008. Right now, I have a huge list of dll and lib dependencies and I am adding some more. I worry that when I need to update a dependency by building from source (where I have to manually replace built dlls and libs in the correct place), if I accidently forgot to replace something or vice versa, I may run into a compile and/or runtime problem. And finding which place goes wrong can be a bit difficult. So is there some sort of program or method out there that can suit this task to ease building a program with many updating dependencies?

• What is wrong with this database query?

  - by outsyncof

  I have the following tables in a database (i'll only list the important attributes): Person(ssn,countryofbirth) Parents(ssn,fatherbirthcountry) Employment(ssn, companyID) Company(companyID, name) My task is this: given fatherbirthcountry as input, output the names of companies where persons work whose countryofbirth match the fatherbirthcountry input. I pretend that the fatherbirthcountry is Mexico and do this: SELECT name FROM Company WHERE companyid = (SELECT companyid FROM Employment WHERE ssn = (SELECT ssn FROM Person WHERE countryofbirth = 'Mexico'); but it is giving me an error: >Scalar subquery is only allowed to return a single row. am I completely off track? Can anybody please help?

• My Header over External Content

  - by TrivaniJoanne

  I can see this web site is somewhat over my head, but I'm having trouble finding an answer. I want to put my header, with links to other pages, over external content. Here's why: My MLM gives me a replicated web site that they maintain. I want to add links to my blog, contact info, even meta tags to the site. I though I had it done by using an iframe. I have my content at the top, and the MLM site shows up in the iframe. (here is the link www.trivanijoanne.com) The problem is that the iframe doesn't resize when the external content changes, and it is confusing for the user to need to scroll up to see the page. Also, the pdf pages don't load inside the iframe. I looked around online and see that iframes are a thing of the past. What should I be using to accomplish this task?

• Sending Subversion Change Log Info Via Hudson

  - by GrumpyCanuck

  I'm trying to integrate Hudson into our development process, and everything is going smooth except for one thing. I had been using Phing to do deployments, and one of the things that was being triggered was an email to our tech support email address containing a list of all the commit messages between the last time code was deployed and the present SVN revision. I was doing something like this: read in a file from the root directory of the currently-deployed application that contains the SVN revision when the app was deployed place that value in a Phing variable insert that value into a command to send the SVN commit messages via email create a file in the root directory of the newly-deployed application that contains the current SVN revision I'd like to be able to add that information to the email that gets sent out by Hudson when a successful build goes out. Any pointers on how to accomplish this task in Hudson would be greatly appreciated.

• taskbar-free window manager

  - by 7vies

  I'm looking for a window manager that is not based on the "standard" taskbar (which I find a poor idea and I'm completely tired of). I'm aware of tiling window managers and improvements in last versions of operating systems, but I can't find what I need. I suppose that any window takes the whole screen (or can be tiled), and I imagine switching between windows like that: on a hotkey or mouse hot zone the screen becomes a task switcher where tasks are organized in a somewhat convenient manner. Well, it's a bit like a taskbar with autohide, but I think there could be some more convenient ideas than simply stacking icons and descriptions... It is also supposed to be lightweight enough, for example to run on a netbook. Any suggestions?

• Named semaphores in Python?

  - by Boaz

  Hi, I have a script in python which uses a resource which can not be used by more than a certain amount of concurrent scripts running. Classically, this would be solved by a named semaphores but I can not find those in the documentation of the multiprocessing module or threading . Am I missing something or are named semaphores not implemented / exposed by Python? and more importantly, if the answer is no, what is the best way to emulate one? Thanks, Boaz PS. For reasons which are not so relevant to this question, I can not aggregate the task to a continuously running process/daemon or work with spawned processed - both of which, it seems, would have worked with the python API.

• Debug C# Windows Service

  - by Goober

  Scenario I've got a windows service written in C#. I've read all the google threads on how to debug it, but I still can't get it to work. I've run "PathTo.NetFramework\InstallUtil.exe C:\MyService.exe"........It said the install was successful, however when I run "Services.msc", The service isn't displayed at all, anywhere. If I go into Task Manager, there is a process called "MyService.vshost.exe".....pretty sure that's not it, because it's a service, not a process........Any suggestions and/or help? Greatly appreciated. Other I'm running VS2008.

• How to develop a site for multiple browsers these days ?

  - by Misha Moroshko

  I would like to develop a site that works in all major browsers. I wonder what tools are available these days that may help me to check the functionality across browsers. I mean after I add some functionality to my site, I want to check it in all browsers. Are there any tools/software for this task ? I understand that it's impossible to check everything because it is pretty subjective if something works as expected or not, but maybe there are some tools that may found major errors (like IE is not supporting indexOf).

• SFTP transfer file and move file to folder

  - by molecule

  Hi all, This is my first post so please excuse my ignorance. I am using a vbscript to zip all .csv type files in a particular folder. After some google searches, I have found a workable vbscript to do this and have enabled a scheduled task to automate this. What I need to do next is to transfer the zip file via sftp and then "move" that zip file into another folder. I believe the former can be achieved using pscp.exe via command line but can someone show me how to do the latter? Basically the zipping will be done twice a day and so it will have a timestamp similar to yyyymmdd0900.zip (for 9am schedule) and yyyymmdd1800.zip (for 6pm schedule). After the transfer, I want to move (not copy) the zip file generated into another folder. Any pointers would be greatly appreciated. Thank you all in advance.

• What are people's opinions vis-a-vis my choice of authorization plugins?

  - by brad

  I'm slowly but surely putting together my first rails app (first web-app of any kind in fact - I'm not really a programmer) and it's time to set up a user registration/login system. The nature of my app is such that each user will be completely separated from each other user (except for admin roles). When users log in they will have their own unique index page looking at only their data which they and no-one else can ever see or edit. However, I may later want to add a role for a user to be able to view and edit several other user's data (e.g. a group of users may want to allow their secretary to access and edit their data but their secretary would not need any data of their own). My plan is to use authlogic to create the login system and declarative authorization to control permissions but before I embark on this fairly major and crucial task I thought I would canvas a few opinions as to whether this combo was appropriate for the tasks I envisage or whether there would be a better/simpler/faster/cheaper/awesomer option.

• Best way to auto-restore db on an houlry basis

  - by aron

  Hello, I have a demo site where anyone can login and test a management interface. Every hour I would like to flush all the data in the SQL 2008 Database and restore it from the original. Rae Gate sql has some awesome tools for this, however they are beyond my budget right now. Could I simply make a backup copy of the database's data file, then have a c# console app that deletes it and copies over the original. Then I can have a windows schedule task to run the .exe every hour. It's simple and free... would this work? I'm using SQL Server 2008 R2 Web edition I understand that red gate is technically better because I can set it to analyze the db and only update the records that were altered, and the approach I have above is like a "sledge hammer".

• Self-extracting Delphi program

  - by Steve

  I'm writing an updater program in Delphi7 which will be run once, but needs many files to run. What I'd like the achieve: 1, User runs exe 2, Exe unpacks files, runs updater 3, If updater detects and error, prompts the user to send log in e-mail 4, After the updater is run, temporary files are deleted (some of these files are dlls used by the updater program, so the updater has to be closed before the files can be deleted) Can anyone recommend a good solution? I've thought about using Inno Setup (too complicated for such an easy task) or using a self-extracting zip file (but how to delete the files afterwards)? Thanks!

• Porting Django's templates engine to C

  - by sandra

  Hi folks, I recently wrote a simple and tiny embedded HTTP server for my C++ app (QT) and I played a little bit with Ry's http-parser and loved it. This guy is crazy. So I told to myself: "Hey! Why not port the django template engine to C?" That'd be awesome! I know, it won't be an easy task (not at all, I know) but I'd really love to implement this. So I came here for inspiration, ideas, opinions... I'd really love to have some pointers on the subject, ideas, what is already done, which major problems I'll encounter (and how to solve them) - How not to reinvent the wheel... anyway, you got the idea :) Thanks a million times! P.S. Simple code snippets, and links to tools and libs are very welcome! P.P.S. I'm already aware of grantlee, I took a look into its sources. Well... that's C++ and its specific to Qt.

• Workling not running tasks in background

  - by alex

  Hi, I followed the railscast that describes how to get workling running background tasks, but can't get it working. The task runs, but not in the background (it's taking 5 secs before I'm redirected to admin_path). Here is what my code looks like: class AdminWorker < Workling::Base   def test_workling(options)     sleep 5   end end class AdminController < ApplicationController   def test_workling     AdminWorker.async_test_workling     flash[:notice] = "Doing stuff in the background"     redirect_to admin_path   end end What am I doing wrong? How to debug? Thanks!

• Routinely sync a branch to master using git rebase

  - by m1755

  I have a Git repository with a branch that hardly ever changes (nobody else is contributing to it). It is basically the master branch with some code and files stripped out. Having this branch around makes it easy for me to package up a leaner version of my project without having to strip out the code and files manually every time. I have been using git rebase to keep this branch up to date with the master but I always get this warning when I try to push the branch after rebasing: To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. I then use git push --force and it works but I feel like this is probably bad practice. I want to keep this branch "in sync" with the master quickly and easily. Is there a better way of handling this task?

• C#: standard Windows menu bars in Windows Forms

  - by BoltClock

  I noticed that adding a MenuStrip (from the VS Toolbox) to my form design doesn't yield a menu bar like many native Windows applications. Instead I get a menu bar like VS's own. None of the style settings for MenuStrip appear to mimic the much more common native menu bar. Is there a way to add a menu bar to my Windows Forms application that looks the same as the one you see in Notepad, Task Manager, Windows Explorer and others? (Preferably with the designer, but I wouldn't mind adding it programmatically either.)

• Anyone up to creating a tomcat based alternative for GAE?

  - by bach

  Hi, If we had the possibility to run GAE app without any code change on our servlet engine that would be great because: in case that google changes their billing policy we can just jump to our own server or in case their current policy doesn't fit our app needs we can do stuff which is not allowed in the GAE, compromising a 1 JVM, 1 DB We don't actually need a distributed system but more of a realtime system with synchronize, true locking mechanisms, other servers/software installed on the server machine, socket interface etc... Such a package should include at least: TomCat (or equivalent) DataNucleus Access Platform (Task Queue service) Any idea if it's easy to get such a thing or if it's already exist somewhere? Thanks

• How should I measure Concurrent Licence Usage

  - by Andrew Wood

  Hi I have detailed stats on user access to my system detailing login and logout times as well as machine used, network username etc. I am in need of measuring what I would term a concurrent user licences level based on this information. Now I could take the maximum logged in for any 1 day in a 3 month period say 170 or I could take the average say 133. Does anyone have or know of a formula for working this out or is it as simple as the high water mark which is 170 in my example. A client has recently gone from an unlimited licence to a concurrent licence so I am faced with the task of setting the initial licence level. There is potential for more licence sales in the future so I don't want it set to high and I do want it based on historical data that the system collects rather than guess work.

• How to re-use a thread in Java ?

  - by David

  I am a building a console Sudoku Solver where the main objective is raw speed. I now have a ManagerThread that starts WorkerThreads to compute the neibhbors of each cell. So one WorkerThread is started for each cell right now. How can I re-use an existing thread that has completed its work? The Thread Pool Pattern seems to be the solution, but I don't understand what to do to prevent the thread from dying once its job has been completed. ps : I do not expect to gain much performance for this particular task, just want to experiment how multi-threading works before applying it to the more complex parts of the code. Thanks

  We wanna a c# solution to correct the scanned image becouse it is rotated and to solve this problem we must detect the rotation angle first then rotate the image.this was our first thinking for our problem then we think image warping will be more accurate as i think it will make the scanned image like our template so we can process it as we know all the coordinates of our template ....... i search for a free SDK or a free solution in c# and helping me in this will be graet work as it is the last task in our working. rally thanxxxx for all.

• Testing perceived performance

  - by Josh Kelley

  I recently got a shiny new development workstation. The only disadvantage of this is that the desktop apps I'm developing now run very, very fast, and so I fear that parts of the code that would be annoyingly slow on end users' machines will go unnoticed during my testing. Is there a good way to slow down an application for testing? I've tried searching around, but all of the results I've been able to find seem pretty fiddly to set up (e.g., manually setting up a high-priority CPU-bound task on the same CPU core as the target app, or running a background process that rapidly interrupts and resumes the target app), and I don't know if the end result is actually a good representation of running on a slower computer (with its slower CPU, slower RAM, slower disk I/O...). I don't think that this is a job for a profiler; I'm interested in the user's perception of end-to-end performance rather than in where the time goes for particular operations.
