• What is the best way to design a table with an arbitrary id?

  - by P.Brian.Mackey

  I have the need to create a table with a unique id as the PK. The ID is a surrogate key. Originally, I had a natural key, but requirement changes have undermined this idea. Then, I considered adding an auto incrementing identity. But, this presents problems. A. I can't specify my own ID. B. The ID's are difficult to reset. Both of these together make it difficult to copy over this table with new data or move the table across domains, e.g. Dev to QA. I need to refer to these ID's from the front end, JavaScript...so they must not change. So, the only way I am aware of to meet all these challenges is to make a GUID ID. This way, I can overwrite the ID's when I need to or I can generate a new one without concern for order (E.G. an int based id would require I know the last inserted ID). Is a GUID the best way to accomplish my goals? Considering that a GUID is a string and joining on a string is an expensive task, is there a better way?

• Commit into TortoiseSVN

  - by pratap

  hello, <exec executable="tortoiseproc.exe"> <baseDirectory>C:\Program Files\TortoiseSVN\bin</baseDirectory> <buildArgs>/command:commit /path:\******\trunk\dotnet /notempfile /closeonend</buildArgs> <buildTimeoutSeconds>1000</buildTimeoutSeconds> </exec> the code above pops up a window asking for "entering a message, selecting the changed content and then clicking OK and again clicking OK again after the process completes" I would be extremely thankful if anyone can suggest how to avoid the above said process if commit is done using cruise control (config file). thanks. pratap

• Java Backgroundworker: Scope of Widget to be updated unclear

  - by erlord

  Hi all, I am trying to understand the mechanism of org.jdesktop.swingx.BackgroundWorker. Their javadoc presents following example: final JLabel label; class MeaningOfLifeFinder implements BackgroundListener { public void doInBackground(BackgroundEvent evt) { String meaningOfLife = findTheMeaningOfLife(); evt.getWorker().publish(meaningOfLife); } public void process(BackgroundEvent evt) { label.setText("" + evt.getData()); } public void done(BackgroundEvent evt) {} public void started(BackgroundEvent evt) {} } (new MeaningOfLifeFinder()).execute(); Apart from the fact that I doubt the result will ever get published, I wonder how label is passed to the process method, where it is being updated. I thought it's scope is limited to the outside of the BackgroudListener implementation. Quite confused I am ... any answers for me? Thanks in advance

• architecture python question

  - by tom smith

  hi. creating a distributed crawling python app. it consists of a master server, and associated client apps that will run on client servers. the purpose of the client app is to run across a targeted site, to extract specific data. the clients need to go "deep" within the site, behind multiple levels of forms, so each client is specifically geared towards a given site. each client app looks something like main: parse initial url call function level1 (data1) function level1 (data) parse the url, for data1 use the required xpath to get the dom elements call the next function call level2 (data) function level2 (data2) parse the url, for data2 use the required xpath to get the dom elements call the next function call level3 function level3 (dat3) parse the url, for data3 use the required xpath to get the dom elements call the next function call level4 function level4 (data) parse the url, for data4 use the required xpath to get the dom elements at the final function.. --all the data output, and eventually returned to the server --at this point the data has elements from each function... my question: given that the number of calls that is made to the child function by the current function varies, i'm trying to figure out the best approach. each function essentialy fetches a page of content, and then parses the page using a number of different XPath expressions, combined with different regex expressions depending on the site/page. if i run a client on a single box, as a sequential process, it'll take awhile, but the load on the box is rather small. i've thought of attempting to implement the child functions as threads from the current function, but that could be a nightmare, as well as quickly bring the "box" to its knees! i've thought of breaking the app up in a manner that would allow the master to essentially pass packets to the client boxes, in a way to allow each client/function to be run directly from the master. this process requires a bit of rewrite, but it has a number of advantages. a bunch of redundancy, and speed. it would detect if a section of the process was crashing and restart from that point. but not sure if it would be any faster... i'm writing the parsing scripts in python.. so... any thoughts/comments would be appreciated... i can get into a great deal more detail, but didn't want to bore anyone!! thanks! tom

• Google Checkout, OpenId, and downloadable products

  - by craigmoliver

  I going to use Google Checkout to process orders to purchase downloadable content. When the order process is completed via Google Checkout I'd like for the user to be able come back to my site, authenticate using their Google credentials (OpenID?) that they purchased the item with linked back end, and download the goods. The site is written using C# and ASP.NET MVC. Is this possible or how should I rethink this? Are there open-source libraries to get me started?

• How do I indicate success and failure with colour?

  - by Steve McLeod

  I need to make a Java component that turns the background a certain colour when a process passed, and another colour when the process failed. My first thought was: green for success, red for failure. But then I read that 10% of males can't differentiate between these two colours. What would be a better combination of colours? (For the nitpickers: yes, I know that colour alone doesn't suffice, that text, shape, and noise can also be used. Nevertheless I am asking about the appropriate use of colour.)

• msmq binding wcf

  - by pdiddy

  I have some messages in my queue. Now I notice that after 3 tries the service host faults. Is this a normal behavior? Where does the 3 times comes from? I thought it came from receiveRetryCount. But I set that one to 1. I got 20 messages in my queue waiting to be processed. The WCF operation that is responsible to process the message supports transaction so if it can't process the message it will throw so that the message stays in the queue. I didn't think that it would of Fault the ServiceHost after a number of retry, is this part documented somewhere? I'm running MSMQ service on my winxp machine. I'm more interested in documentation indicating that the service host will fault after a number of retry. Is this part true?

• Microsoft Detours

  I am new to Microsoft Detours. I have installed it to trace the system calls a process makes. I run the following commands which I got from the web syelogd.exe /q C:\Users\xxx\Desktop\log.txt withdll.exe /d:traceapi.dll C:\Program Files\Google\Google Talk\googletalk.exe I get the log file. The problem is I don't fully understand what is happening here. How does detours work? How does it trace the system calls? Also I don't know how to read the output in log.txt. Here is one line in log.txt 20101221060413329 2912 50.60: traceapi: 001 GetCurrentThreadId() Finally I want to get the stack trace of the process. How can I get that?

• #altnetseattle &ndash; MEF, What is it?

  - by GeekAgilistMercenary

  I dived into the MEF session with Glenn Block, Sourabh Mathur, Brian Henderson, and others.  Glenn covered the basic architectural ideas of MEF and then dived into a few examples. Is a framework around decoupling components. Built around the idea of discoverable type systems. Traditional extensibility mechanisms have a host and the respective extensions, commonly linking these two aspects with a form of registration. MEF removes the need for the registration part of the architecture and uses a contract. At some point with MEF you get down to parts, which removes even the complexity of a host or extensions, but a truly evolvable architecture based on natural growth of parts. Also referred to as the framework that removes the "new" keyword. The idea is that parts pull together other parts that they need.  Between each part is a contract. Each part has imports or exports for the parts it needs or the things it offers. If one checks out the MEF Codeplex Site you will find a host of additional information.  The framework download also has some decent examples that help one get kick started.

• Init modules in apache2

  - by user306963

  Hello, I used to write apache modules in apache 1.3, but these days I am willing to pass to apache2. The module that I am writing at the moment has is own binary data, not a database, for performance purposes. I need to load this data in shared memory, so every child can access it without making his own copy, and it would be practical to load/create the binary data at startup, as I was used to do with apache 1.3. Problem is that I don't find an init event in apache2, in 1.3 in the module struct, immediatly after STANDARD_MODULE_STUFF you find a place for a /** module initializer */, in which you can put a function that will be executed early. Body of the function I used to write is something like: if ( getppid == 1 ) { // Load global data here // this is the parent process void* data = loadGlobalData( someFilePath ); setGlobalData( config, data ); } else { // this is the init of a child process // do nothing } I am looking for a place in apache2 in where I can put a similar function. Can you help? Thanks Benvenuto

• Automate Testing on future only items business rules

  - by Titan

  I currently have a business object with a validation business rule, which is it can only be created for the future, tomorrow onwards, and I cannot create new items for today. I have a process, which runs the non-future business objects through some steps.. Because I have to set things up today, and test tomorrow, and when it fails, I can only create a new object tomorrow and test the following day. Are there any easy ways to automate this process in any testing frameworks? I think our testers are using the visual studio 2010 test manager. How do you guys manage situations like this? Cheers

• In-Proc SxS opens for shell extension in managed code?

  - by Jens Granlund

  The recommendation used to be "Do not write in-process shell extensions in managed code." But with .NET Framework 4 and In-Process Side-by-Side the main reason not to write shell extensions in managed code should be resolved. With that said, I have three questions. Is it now okay to write shell extensions in managed code? Which problems, if any might there be with writing shell extensions in managed code? What reasons might there be to write shell extensions in unmanaged code?

• Control Windows VM from Linux Host

  - by vy32

  I am looking for a tool that will allow me to monitor and control programs running inside a Windows VM from the Linux host machine. I realize that this is similar to what a rootkit would do, and I am completely happy to use some hacker software if it provides the necessary functionality (and if I can get it in source-code form). If I can't find something, I'll have to write it using C. Probably an embedded HTTP server running on an odd port and doing some kind of XMLRPC thing. Here is the basic functionality I need: Get list of running processes Kill a process. Start a process Read/write/create/delete files I would like to: - Read contents of screen - Read all controls on screen. - Send arbitrary click to a Windows control. Does anything like this exist?

• Linux ext3 readdir and concurrent updates

  - by Wangnick

  Dear all, we are receiving about 10000 messages per hour. We store them as individual files in hourly directories on an ext3 filesystem. The file name includes a sequence number. We use rsync to mirror these files every 20 seconds at another location (via a SAN, but that doesn't matter). Sometimes an rsync run picks up files n-3, n-2, n-1, n+1, and then next rsync run continues with n, n+2, n+3, n+4 and so on. Is it possible that when one process creates files in a certain sequence within a directory, that another process using readdir() sees the files appearing in a different sequence? Kind regards, Sebastian

• What happens when you run out of ram with mlockall set?

  - by James Dean

  I am working on a C++ application that requires a large amounts of memory for a batch run. ( 20gb) Some of my customers are running into memory limits where sometimes the OS starts swapping and the total run time doubles or worse. I have read that I can use the mlockall to keep the process from being swapped out. What would happen when the process memory requirements approaches or exceeds the the available physical memory in this way? I guess the answer might be OS specific so please list the OS in your answer.

• Avoiding exceptions when uploading files in laravel

  - by occam98

  I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

• Multiple merchant accounts with Activemerchant gem.

  - by sosborn

  I am developing a rails site that will allow a group of merchants (5 - 10) to accept credit card orders online. I plan on using the Activemerchant gem to handle the processing. In this case, each merchant will have their own merchant accounts to handle the payments. Storing banking information like that is not something I am a fan of. This could be solved by queing orders and allowing the merchant to log in to the site, input their credentials and process the order. However, if I go that route then it seems to me that I would have to store the customers' credit card information temporarily until the merchant has the opportunity to log in and process the order, which to me is the greater evil. Has anyone dealt with this situation? If so, what are the options available and what pitfalls should I look out for? In my mind, security customer credit card information is priority number one with the merchant account information a close second.

• Multiple Socket Connections

  - by BSchlinker

  I need to write a server which accepts connections from multiple client machines, maintains track of connected clients and sends individual clients data as necessary. Sometimes, all clients may be contacted at once with the same message, other times, it may be one individual client or a group of clients. Since I need confirmation that the clients received the information and don't want to build an ACK structure for a UDP connection, I decided to use a TCP streaming method. However, I've been struggling to understand how to maintain multiple connections and keep them idle. I seem to have three options. Use a fork for each incoming connection to create a separate child process, use pthread_create to create an entire new thread for each process, or use select() to wait on all open socket IDs for a connection. Recommendations as to how to attack this? I've begun working with pthreads but since performance will likely not be an issue, multicore processing is not necessary and perhaps there is a simpler way.

• Recreation of MySQL DB using "mysql mydb < mydb.sql" is really slow when the table has tens of milli

  - by Jian Lin

  It seems that a MySQL database that has a table with tens of millions of records will get a big INSERT INTO statement when the following mysqldump some_db > some_db.sql is done to back up the database. (is it 1 insert statement that handles all the records?) So when reconstructing the DB using mysql some_db < some_db.sql then the CPU is hardly busy (about 1.8% usage by the mysql process... I don't see a mysqld either?) and also the hard disk doesn't seem to be too busy... Last time, the whole restore process took 5 hours. Is there a way to make it faster? Such as, when doing mysqldump, can it break the INSERT statement into shorter ones, so that the mysql doesn't need to parse the line so hard when restoring the DB?

• unit/integration testing web service proxy client

  - by cori

  I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

• Examples of 2D side-scrollers that achieve open non-linear feel?

  - by Milosz Falinski

  I'm working on a 2.5D platformer prototype that aims for an open feel while maintaining familiar core mechanics. Now, there's some obvious challenges with creating a non constricted feel in a spatially constricted environment. What I'm interested in, is examples of how game designers deal with the "here's a level, beat the bad guys/puzzles to get to the next level" design that seems so natural to most platformers (eg. Mario/Braid/Pid/Meat Boy to name a few). Some ideas for achieving openness I've come across include: One obvious successful example is Terraria, which achieves openness simply through complexity and flexibility of the game-system Another example that comes to mind is Cave Story. Game is non-linear, offers multiple choices and side-stories Mario, Rayman and some other 'classics' with a top-down level selection. I actually really dislike this as it never did anything for me emotionally and just seems like a bit of a lazy way to do things. Note: I've not actually had much experience with most of the 'classical' console platformers, apart from the obvious Marios/Zeldas/Metroids, since I've grown up on adventure games. By that I mean, it's entirely possible that I simply missed some games that solve the problem really well and are by some considered obvious 'classics'.

• MYSQL Event to update another database table

  - by Lee

  Hey All, I have just taken over a project for a client and the database schema is in a total mess. I would like to rename a load of fields make it a relationship database. But doing this will be a painstaking process as they have an API running of it also. So the idea would be to create a new database and start re-writing the code to use this instead. But I need a way to keep these tables in sync during this process. Would you agree that I should use MYSQL EVENT's to keep updating the new table on Inserts / updates & deletes?? Or can you suggest a better way?? Hope you can advise !! thanks for any input I get

• Dealing with the customer / developer culture mismatch on an agile project

  - by Eric Smith

  One of the tenets of agile is ... Customer collaboration over contract negotiation ... another one is ... Individuals and interactions over processes and tools But the way I see it, at least when it comes to interaction with the customer, there is a fundamental problem: How the customer thinks is fundamentally different to how a software engineer thinks That may be a bit of a generalisation, yes. Arguably, there are business domains where this is not necessarily true---these are few and far between though. In many domains though, the typical customer is: Interested in daily operational concerns--short-range tactics ... not strategy; Only concerned with the immediate solution; Generally one-dimensional, non-abstract thinkers; Primarily interested in "getting the job done" as opposed to coming up with a lasting, quality solution. On the other hand, software engineers who practice agile are: Professionals who value quality; Individuals who understand the notion of "more haste less speed" i.e., spending a little more time to do things properly will save lots of time down the road; Generally, very experienced analytical thinkers. So very clearly, there is a natural culture discrepancy that tends to inhibit "customer collaboration". What's the best way to address this?
