• iPhone Developer Program registration for UK trading partnership

  - by CMLloyd

  I have been looking into this for a long time and have found no definitive answer. I can't be the only person to have faced this problem and am wondering how you guys proceeded in similar cases. I'm part of a partnership, based in the UK, trading as, lets say, "ABCD iPhone Apps" (legally, a perfectly legitimate way of doing business). I've now developed an iPhone App and I want our company name ("ABCD iPhone Apps") to appear as the seller in the App Store. This way, any future Apps that we develop can all get released under the "ABCD iPhone Apps" aegis too. Given that we aren't an incorporated company (and probably never will be), is it possible for us to enroll in the iPhone Developer Program as a company? Or is there another solution? (Note: I do also have an Individual account but that is for personal projects and is in no way connected to the partnership, and shall remain that way) EDIT: I've just spoken to a guy at ADC UK and he tells me there is no other solution. For a company to be approved on the Developer Program, Apple needs to see a copy of the company's Certificate of Incorporation during the registration process, otherwise no approval.

• C# Application Calling Powershell Script Issues

  - by Ben

  Hi, I have a C# Winforms application which is calling a simple powershell script using the following method: Process process = new Process(); process.StartInfo.FileName = @"powershell.exe"; process.StartInfo.Arguments = String.Format("-noexit \"C:\Develop\{1}\"", scriptName); process.Start(); The powershell script simply reads a registry key and outputs the subkeys. $items = get-childitem -literalPath hklm:\software foreach($item in $items) { Write-Host $item } The problem I have is that when I run the script from the C# application I get one set of results, but when I run the script standalone (from the powershell command line) I get a different set of results entirely. The results from running from the c# app are: HKEY_LOCAL_MACHINE\software\Adobe HKEY_LOCAL_MACHINE\software\Business Objects HKEY_LOCAL_MACHINE\software\Helios HKEY_LOCAL_MACHINE\software\InstallShield HKEY_LOCAL_MACHINE\software\Macrovision HKEY_LOCAL_MACHINE\software\Microsoft HKEY_LOCAL_MACHINE\software\MozillaPlugins HKEY_LOCAL_MACHINE\software\ODBC HKEY_LOCAL_MACHINE\software\Classes HKEY_LOCAL_MACHINE\software\Clients HKEY_LOCAL_MACHINE\software\Policies HKEY_LOCAL_MACHINE\software\RegisteredApplications PS C:\Develop\RnD\SiriusPatcher\Sirius.Patcher.UI\bin\Debug When run from the powershell command line I get: PS M: C:\Develop\RegistryAccess.ps1 HKEY_LOCAL_MACHINE\software\ATI Technologies HKEY_LOCAL_MACHINE\software\Classes HKEY_LOCAL_MACHINE\software\Clients HKEY_LOCAL_MACHINE\software\Equiniti HKEY_LOCAL_MACHINE\software\Microsoft HKEY_LOCAL_MACHINE\software\ODBC HKEY_LOCAL_MACHINE\software\Policies HKEY_LOCAL_MACHINE\software\RegisteredApplications HKEY_LOCAL_MACHINE\software\Wow6432Node PS M: The second set of results match what I have in the registry, but the first set of results (which came from the c# app) don't. Any help or pointers would be greatly apreciated :) Ben

• Ruby on rails generates tests for you. Do those give a false sense of a safety net?

  - by Hamish Grubijan

  Disclaimer: I have not used RoR, and I have not generated tests. But, I will still dare to post this question. Quality Assurance is theoretically impossible to get 100% right in general (Undecidable problem ;), and it is hard in practice. So many developers do not understand that writing good automated tests is an art, and it is hard. When I hear that RoR generates the tests for you, I get very skeptical. It cannot be that easy. Testing is a general concept; it applies across languages. So does the concept of code contracts, it is similar for languages that support it. Code contracts do not generate themselves. The programmer must add the requirements and the promises manually, after doing some thinking about the algorithm / function. If a human gets it wrong, then the tools will propagate the error. Similarly with testing - it takes human judgement about what should happen. Tests do not write themselves, and we are far from the day when a business analyst can just have a conversation with a computer and tell it informally what the requirements are and have the computer do all the work. There is no magic ... how can RoR generate good tests for you? Please shed some light on this. Opinions are ok, for this is a community wiki. Thanks!

• NSURLErrorBadURL error

  - by Victor jiang

  My iphone app called Google Local Search(non javascript version) to behave some search business. Below is my code to form a url: NSString *url = [NSString stringWithFormat:@"http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=%@", keyword]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:url]]; [request setHTTPMethod:@"GET"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[[NSError alloc] init] autorelease]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; When the keyword refers to english characters, it works fine, but when refers to chinese characters(encoded in UTF8, such as '???' whose UTF8 code is 'e5a4a9 e5ae89 e997a8'), it will report NSURLErrorBadURL error(-1000, Returned when a URL is sufficiently malformed that a URL request cannot be initiated). Why? Then I carry out further investigation, I use Safari and type in the url below: http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=??? It also works, and the output I got from Macsniffer is: /ajax/services/search/local?v=1.0&q=%E5%A4%A9%E5%AE%89%E9%97%A8 So I write a testing url directly in my app NSString *url = [NSString stringWithFormat:@"http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=%E5%A4%A9%E5%AE%89%E9%97%A8"]; And what I got from the Macsniffer is some other thing: /ajax/services/search/local?v=1.0&q=1.687891E-28750X1.417C0001416CP-102640X1.4CC2D04648FBP-9999-1.989891E+0050X1.20DC00184CC67P-953E8E99A8 It seems my keyword "%E5%A4%A9%E5%AE%89%E9%97%A8" was translated into something else. So how can I form a valid url? I do need help!

• Is VB Really Case Insensitive?

  - by Otaku

  I'm not trying to start an argument here, but for whatever reason it's typically stated that VB is case insensitive and C languages aren't (and somehow that is a good thing). But here's my question: Where exactly is VB case insensitive? When I type... Dim ss As String Dim SS As String ...into the VS2008 IDE the second one has a warning of "Local variable 'SS' is already declared in the current block". In VBA VBE, it doesn't immediately kick an error, but rather just auto-corrects the case. Am I missing something here with this argument that VB is not case sensitive? (Also, if you know or care to answer, why would that be a bad thing?) EDIT: Why am I even asking this question? I've used VB in many of it's dialects for years now, sometimes as a hobbyist, sometimes for small business-related programs in a workgroup. As of the last 6 months I've been working on a big project, much bigger than I anticipated. Much of the sample source code out there is in C#. I don't have any burning desire to learn C#, but if there are things I'm missing out on that C# offers that VB doesn't (an opposite would be VB.NET offers XML Literals), then I'd like to know more about that feature. So in this case, it's often argued that C languages are case sensitive and that's good and VB is case insensitive and that is bad. I'd like to know A) how exactly is VB case insensitive because every single example in the code editor becomes case sensititive (meaning case gets corrected) whether I want it or not and B) is this compelling enough for me to consider moving to C# if VB.NET case is somehow limiting what I could do with code?

  I'm trying to export an Excel database into .txt (Tab Delimited), but some of my cells are quite large. When I export into a txt some of the cells are exported as '#######....' which is surprisingly useless. Has this happened to anyone else? Do you know an easy fix?

• What are best practices for collecting, maintaining and ensuring accuracy of a huge data set?

  - by Kyle West

  I am posing this question looking for practical advice on how to design a system. Sites like amazon.com and pandora have and maintain huge data sets to run their core business. For example, amazon (and every other major e-commerce site) has millions of products for sale, images of those products, pricing, specifications, etc. etc. etc. Ignoring the data coming in from 3rd party sellers and the user generated content all that "stuff" had to come from somewhere and is maintained by someone. It's also incredibly detailed and accurate. How? How do they do it? Is there just an army of data-entry clerks or have they devised systems to handle the grunt work? My company is in a similar situation. We maintain a huge (10-of-millions of records) catalog of automotive parts and the cars they fit. We've been at it for a while now and have come up with a number of programs and processes to keep our catalog growing and accurate; however, it seems like to grow the catalog to x items we need to grow the team to y. I need to figure some ways to increase the efficiency of the data team and hopefully I can learn from the work of others. Any suggestions are appreciated, more though would be links to content I could spend some serious time reading. THANKS! Kyle

• Best practice for structuring a new large ASP.NET MVC2 plus EF4 VS2010 solution?

  - by Nick

  Hi, we are building a new web application using Microsoft ASP.NET MVC2 and Entity Framework 4. Although I am sure there is not one right answer to my question, we are struggling to agree a VS2010 solution structure. The application will use SQL Server 2008 with a possible future Azure cloud version. We are using EF4 with T4 POCOs (model-first) and accessing a number of third-party web-services. We will also be connecting to a number of external messaging systems. UI is based on standard ASP.NET (MVC) with jQuery. In future we may deliver a Silverlight/WPF version - as well as mobile. So put simply, we start with a VS2010 blank solution - then what? I have suggested 4 folders Data (the EF edmx file etc), Domain (entities, repositories), Services (web-services access), Presentation (web ui etc). However under Presentation, creating the ASP.NET MVC2 project obviously creates it's own Models folder etc and it just doesn't seem to fit too well in this proposed structure. I'm also missing a business layer (or does this sit in the domain?). Again I am sure there is no one right way to do it, but I'd really appreciate your views on this. Thanks

• How to implement a .net 3-tier architecture using Winforms

  - by Anders Jakobsen

  I have for some time build n-tier Applications using a database server as the data tier, Winforms as the presentation tier and an ASP.NET asmx webservice in the middle to send back and forth untyped Datasets. While this approach has worked for me so far, it certainly does feel outdated today. What technologies should I use if I were to create a similar architectured application today? .net 4.0 technology is welcome. I still want a database server as the datatier and the asmx webservices should probably be replaced by WCF. I would still like to have the presentation tier running as a desktop application (Winforms or WPF) so ignore ASP.net for this question. My main question really comes down to what to use as business objects. I want something that is easier to bind to the interface than untyped Datasets and strongly-typed datasets feels very heavy. I also need something that can track changes to make sure users do not override each other's changes in the database. Will the Entity Framework 4 be usable for a scenario like this? Are there any thorough guides available?

• Need help figuring out an appropriate job title

  - by Programmer

  My official title is Programmer but I do not feel it fully represents what I do because a large portion of my time is spent working with QA on testing, acting as a liason with our offshore development team and meeting with business managers to help make decisions about new features. My understanding has always been that the title "Programmer" is usually applied to someone who simply writes code, not someone who is involved in architecture decisions or managerial issues related to offshore teams. It is true that I do not have any budgeting duties as my manager does and I do not deal with contracts related to the offshore development. My manager handles both of those duties. But the title "Programmer" seems like a very narrow label for the broad range of responsibilities that I have. For example, I sometimes help QA staff to figure out how to do their testing. And I give the offshore team detailed instructions about how to implement new features - I review their code and integrate their changes locally. I don't know if this is typical these days or if I should ask for a title change. If I should ask for a title change, I would appreciate any recommendations.

• NSXMLParser: how do I wait until loading has finished?

  - by Archagon

  Let's say I'm using NSXMLParser to load a level (stored as an XML document, obviously) into my iPhone game. NSXMLParser works by assigning a delegate and sending it messages at key moments. How do I ensure that my entire level is loaded before doing anything else? I know I can make my main class the delegate and implement parserDidEndDocument, but this feels very hacky. My main class shouldn't have to know anything about the way the parsing is done! On the other hand, if I make a separate class/delegate for parsing my level, my main class has no way of knowing when the parsing is finished, unless it queries the parsing class continuously or the parsing class sends it a message. Either way, the main class would be tied to the implementation of the parsing class. Can I hide all this event-driven business from the main class and simply make the parser return the level object when it's done? (i.e., newLevel = [[GameLevel alloc] initFromXML:xmlfile], which would in turn use NSXMLParser to load the level and then somehow return when finished.) At the moment, I'm using an external DOM parser, but I'm curious how this would be done with NSXMLParser. Sorry if this is a stupid question -- I'm a bit new to this!

• Could CouchDB benefit significantly from the use of BERT instead of JSON?

  - by Victor Rodrigues

  I appreciate a lot CouchDB attempt to use universal web formats in everything it does: RESTFUL HTTP methods in every interaction, JSON objects, javascript code to customize database and documents. CouchDB seems to scale pretty well, but the individual cost to make a request usually makes 'relational' people afraid of. Many small business applications should deal with only one machine and that's all. In this case the scalability talk doesn't say too much, we need more performance per request, or people will not use it. BERT (Binary ERlang Term http://bert-rpc.org/ ) has proven to be a faster and lighter format than JSON and it is native for Erlang, the language in which CouchDB is written. Could we benefit from that, using BERT documents instead of JSON ones? I'm not saying just for retrieving in views, but for everything CouchDB does, including syncing. And, as a consequence of it, use Erlang functions instead of javascript ones. This would modify some original CouchDB principles, because today it is very web oriented. Considering I imagine few people would make their database API public and usually its data is accessed by the users through an application, it would be a good deal to have the ability to configure CouchDB for working faster. HTTP+JSON calls could still be handled by CouchDB, considering an extra cost in these cases because of parsing.

• DDD: Aggregate Roots

  - by Mosh

  Hello, I need help with finding my aggregate root and boundary. I have 3 Entities: Plan, PlannedRole and PlannedTraining. Each Plan can include many PlannedRoles and PlannedTrainings. Solution 1: At first I thought Plan is the aggregate root because PlannedRole and PlannedTraining do not make sense out of the context of a Plan. They are always within a plan. Also, we have a business rule that says each Plan can have a maximum of 3 PlannedRoles and 5 PlannedTrainings. So I thought by nominating the Plan as the aggregate root, I can enforce this invariant. However, we have a Search page where the user searches for Plans. The results shows a few properties of the Plan itself (and none of its PlannedRoles or PlannedTrainings). I thought if I have to load the entire aggregate, it would have a lot of overhead. There are nearly 3000 plans and each may have a few children. Loading all these objects together and then ignoring PlannedRoles and PlannedTrainings in the search page doesn't make sense to me. Solution 2: I just realized the user wants 2 more search pages where they can search for Planned Roles or Planned Trainings. That made me realize they are trying to access these objects independently and "out of" the context of Plan. So I thought I was wrong about my initial design and that is how I came up with this solution. So, I thought to have 3 aggregates here, 1 for each Entity. This approach enables me to search for each Entity independently and also resolves the performance issue in solution 1. However, using this approach I cannot enforce the invariant I mentioned earlier. There is also another invariant that states a Plan can be changed only if it is of a certain status. So, I shouldn't be able to add any PlannedRoles or PlannedTrainings to a Plan that is not in that status. Again, I can't enforce this invariant with the second approach. Any advice would be greatly appreciated. Cheers, Mosh

• System.Threading.Timer keep reference to it.

  - by Daniel Bryars

  According to [http://msdn.microsoft.com/en-us/library/system.threading.timer.aspx][1] you need to keep a reference to a System.Threading.Timer to prevent it from being disposed. I've got a method like this: private void Delay(Action action, Int32 ms) { if (ms <= 0) { action(); } System.Threading.Timer timer = new System.Threading.Timer( (o) => action(), null, ms, System.Threading.Timeout.Infinite); } Which I don't think keeps a reference to the timer, I've not seen any problems so far, but that's probably because the delay periods used have been pretty small. Is the code above wrong? And if it is, how to I keep a reference to the Timer? I'm thinking something like this might work: class timerstate { internal volatile System.Threading.Timer Timer; }; private void Delay2(Action action, Int32 ms) { if (ms <= 0) { action(); } timerstate state = new timerstate(); lock (state) { state.Timer = new System.Threading.Timer( (o) => { lock (o) { action(); ((timerstate)o).Timer.Dispose(); } }, state, ms, System.Threading.Timeout.Infinite); } The locking business is so I can get the timer into the timerstate class before the delegate gets invoked. It all looks a little clunky to me. Perhaps I should regard the chance of the timer firing before it's finished constructing and assigned to the property in the timerstace instance as negligible and leave the locking out.

• How do I create a C# .NET Web Service that Posts items to a users Facebook Wall?

  - by Jourdan

  I'm currently toying around with the Clarity .NET Facebook API but am finding certain situations with authentication to be kind of limiting. I keep going through the tutorials but always end up hitting a brick wall with what I want to do. Perhaps I just cannot do it? I want to make a Web Service that takes in the require credentials (APIKey, SecretKey, UsersId (or Session Key?) and whatever else I would need), and then do various tasks: Post to users wall, add events etc. The problem I am having is this: The current documentation, examples and support provide a way to do this within the context of a Web site. Within this context, the required "connect" popup can be initiated and allow the user to authenticate and and connect the application. From that point on the Web can go on with its business to do what it needs to do. If I close the browser and come back to the page, I have to push the connect button again. Except this time, since I was already logged into facebook, I don't have to go through the whole connection process. But still ... How do applications like Tweetdeck get around this? They seemingly have you connect once, when you install their application, and you don't have to do it again. I would assume that this same idea would have to applied towards making a web service because: You don't know what context the user is in when making the Web service call. The web service methods being called could be coming from a Windows Form app, or code behind in a workflow.

• Silverlight 4, Out of browser, Printing, Automatic updates

  - by minal

  I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

• How to set "Run this program as an administrator" programatically.

  - by Patrick

  I'm having a problem with good ol' bdeadmin.exe in Vista. First, let's get the predictable responses out of the way: "You should not require your application to be elevated." This one does. C'est la vie. "You need to embed a manifest file." It is already compiled, it is many years old, the company that created it has no intention of doing it again, and it is installed from a Merge Module (MSM file). "BDE is obsolete, you should be using dbExpress" One and a half million lines of code. 'Nuff said. "Drop a manifest file next to the EXE." Tried that, did nothing. As a test, that same manifest file was able to make several other EXE files require elevation, just not the one I wanted. Something in there is preventing the external manifest from being read. "Create a shortcut and set SLDF_RUNAS_USER." Can't do that, it's a Control Panel applet. The only thing that worked was setting "Run this program as an administrator" under the Compatibility tab of its Properties window. I shouldn't have to tell users to do this. Bad for business. I need to have the installer do this. The MSM file uses a static path. Any ideas?

• One Model to Rule Them All - VS2010 UML, ADO.NET Entity Data Model, and T4

  - by Eric J.

  I worked on a fairly large project a while back where we modeled the classes in Enterprise Architect and generated the (partial) POCO classes (complete with model-driven business rule validations), persistence (NHibernate mapping file) and DDL. Based on certain model attributes we could flag alternate generation strategies or indicate that a particular portion would be entirely hand-coded. There was a good deal of initial investment, but it paid large dividends over the lifetime of a 15 developer, 3 year project. I'm investigating doing something similar with the current Microsoft technology stack. The place I'm stuck is that class modeling is done with the VS 2010 UML tools, but logical data modeling is done with Entity Data Modeler. Is it a reasonable path to use VS 2010 UML as the "single source of truth" and code generate the edmx files based on the class model? That's the inverse of the common path to create the entity model and use a POCO generator to generate classes. However, a good class model can be used to generate much more than just the properties so I tend to view it as a better choice than the entity model.

• best practice for directory polling

  - by Hieu Lam

  Hi all, I have to do batch processing to automate business process. I have to poll directory at regular interval to detect new files and do processing. While old files is being processed, new files can come in. For now, I use quartz scheduler and thread synchronization to ensure that only one thread can process files. Part of the code are: application-context.xml <bean id="methodInvokingJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" <property name="targetObject" ref="documentProcessor" / <property name="targetMethod" value="processDocuments" / </bean DocumentProcessor ..... public void processDocuments() { LOG.info(Thread.currentThread().getName() + " attempt to run."); if (!processing) { synchronized (this) { try { processing = true; LOG.info(Thread.currentThread().getName() + " is processing"); List xmlDocuments = documentManager.getFileNamesFromFolder(incomingFolderPath); // loop over the files and processed unlock files. for (String xmlDocument : xmlDocuments) { processDocument(xmlDocument); } } finally { processing = false; } } } } For the current code, I have to prevent other thread to process files when one thread is processing. Is that a good idea ? or we support multi-threaded processing. In that case how can I know which files is being process and which files has just arrived ? Any idea is really appreciated.

• multithreading in c#

  - by Lalit Dhake

  Hi, I have console application. In that i have some process that fetch the data from database through different layers ( business and Data access). stores the fetched data in respective objects. Like if data is fetched for student then this data will store (assigned ) to Student object. same for school. and them a delegate call the certain method that generates outputs as per requirement. This process will execute many times say 10 times. Ok? I want to run simultaneously this process. not one will start, it will finish and then second will start. I want after starting 1'st process, just 2'nd , 3rd....10'th must be start. Means it should be multithreading. how can i achieve this ? is that will give me error while connection with data base open and close ? I have tried this concept . but when thread 1'st is starting then data will fetched for thread 1 will stored in its respective (student , school) objects. ok? when simultaneous 2'nd thread starts , but the data is changing of 1'st object ,while control flowing in program. What have to do?

• Upgrade to Delphi 2010, or stick with Delphi 7 "forever"?

  - by tim11g

  I am an individual user of Delphi, starting back in the early Turbo Pascal days. I have quite a bit of code developed over the years, but I have never sold software commercially or used it for business. Historically, Borland supported the non-professional users with lower cost versions, but Embarcadero does not. As I consider upgrading to Delphi 2010, I am put off by the high price. Embarcadero is also trying to "encourage" upgrading by threatening to charge "new user" prices for upgrades after Dec 31st. I have several questions for the community to help me decide whether to upgrade. 1) I have read about difficulties updating existing code to support the unicode string types. I have no need for unicode strings, and I am happy with the string support in D7. Will I have to modify existing code and components just to re-compile under D2010? Or are there compiler options to allow backward compatibility if new string types are not required? 2) The main reason I'm considering upgrading is for IDE improvements, and to get access to new APIs added to Windows since 2002. Are there any Windows 7 APIs or capabilities that would be impossible to support from my programs compiled using using Delphi 7 (assuming appropriate JEDI API libraries, for example)? 3) Is there anything else about Delphi 2010 that is really compelling for someone who is primarily interested in Win32 apps, and not working with databases? I have read that D2010 is slow to load, and other versions between D7 and D2010 have had stability issues, and the help system was "broken". What is the biggest benefit to D2010?

• How do I manage application configuration in ASP.NET?

  - by GlennS

  I am having difficulty with managing configuration of an ASP.Net application to deploy for different clients. The sheer volume of different settings which need twiddling takes up large amounts of time, and the current configuration methods are too complicated to enable us to push this responsibility out to support partners. Any suggestions for better methods to handle this or good sources of information to research? How we do things at present: Various xml configuration files which are referenced in Web.Config, for example an AppSettings.xml. Configurations for specific sites are kept in duplicate configuration files. Text files containing lists of data specific to the site In some cases, manual one-off changes to the database C# configuration for Windsor IOC. The specific issues we are having: Different sites with different features enabled, different external services we have to talk to and different business rules. Different deployment types (live, test, training) Configuration keys change across versions (get added, remove), meaning we have to update all the duplicate files We still need to be able to alter keys while the application is running Our current thoughts on how we might approach this are: Move the configuration into dynamically compiled code (possibly Boo, Binsor or JavaScript) Have some form of diffing/merging configuration: combine a default config with a live/test/training config and a site-specific config

• Daylight saving time - do and don'ts

  - by Oded

  I am hoping to make this question and the answers to it the definitive guide to dealing with daylight saving time, in particular for dealing with the actual change overs. Many systems are dependent on keeping accurate time, the problem is with changes to time due to daylight savings - moving the clock forward or backwards. For instance, one has business rules in an order taking system that depend on the time of the order - if the clock changes, the rules might not be as clear. How should the time of the order be persisted? There is of course an endless number of scenarios - this one is simply an illustrative one. How have you dealt with the daylight saving issue? What assumptions are part of your solution? (looking for context here) As important, if not more so: What did you try that did not work? Why did it not work? I would be interested in programming, OS, data persistence and other pertinent aspects of the issue. General answers are great, but I would also like to see details especially if they are only available on one platform.

• Need to kill a session?

  - by rob - not a robber

  Really quick here... I think I have the answer, but just looking for some validation. I have a site with two "points of entry." One is for a standard user and one is for an admin account. In the real world, an admin could have a standard user account and try to login as an admin while already being under the standard user session. I have two separate front ends to facilitate login. The normal user one is frilly and has ads and the like, the admin one is strictly business, so any suggestion to have the two user types login through the same "door" is not on the table. Would you advise on the admin login page to destroy any active sessions? Once the admin is in, they'll only be tooling around in their admin area and not on the main site. Has anyone run into probs using this method and having an admin-type user try to log back in in a new window as a "user" to view changes from a logged in user's prespective? Thanks in advance. So many cans of worms :)
