  • How to implement "select sum()" in Grails

    - by xain
    I have a relationship like this: class E { string name hasMany = [me:ME] } class M { float price } class ME { E e M m int quantity } And I'd hate to iterate to achieve this: "obtain the sum of the quantity in ME times the price of the corresponding M for a given E". Any hints on how to implement it using GORM/HQL ? Thanks in advance

  • Why membership provider is not generic?

    - by Timmy O' Tool
    I have to confess that I hate membership provider. The default implementation is not very appropriate normally and I haven't seen so far a good implementation of a custom membership provider, probably because this is not possible :-) So the question is: In your opinion: which are the reasons for not having membership/role provider as a generic class? I mean, why Microsoft didn't selected this approach.

  • Translate a picture to text on Android?

    - by Keith
    I know that google goggles will translate a picture to text. What I want to do is allow the user to take a picture (no problem), translate that picture to text(?) and then do some processing on the text (no problem). Is there any API on android that allows this? or is there any way to programtically communicate with google goggles? I would hate to have the user use goggles then select the saved file with my app.....

  • Best practice- How to team-split a django project while still allowing code reusal

    - by Infinity
    I know this sounds kind of vague, but please let me explain- I'm starting work on a brand new project, it will have two main components: "ACME PRODUCT" (think Gmail, Meebo, etc), and "THE SITE" (help, information, marketing stuff, promotional landing pages, etc lots of marketing-induced cruft). So basically the url /acme/* will load stuff in the uber cool ajaxy application, and every other URI will load stuff in the other site. Problem: "THE SITE" component is out of my hands, and will be handled by a consultants team that will work closely with marketing, And I and my team will work solely on the ACME PRODUCT. Question: How to set up the django project in such a way that we can have: Seperate releases. (They can push new marketing pages and functionality without having to worry about the state of our code. Maybe even separate Subversion "projects") Minimize impact (on our product) of whatever flying-unicorns-hocus-pocus the other team codes into the site. Still allow some code reusal. My main concern is that the ACME product needs to be rock solid, and therefore needs to be somewhat isolated of whatever mistakes/code bloopers the consultants make in their marketing side of the site. How have you handled this? Any ideas? Thanks!

  • Visual Studio 2010 Architecture tooling

    - by Tone
    Has anyone played around with the architecture tools (uml diagrams, etc) in VS 2010 and if so what is your opinion? I really am liking Sparx Systems Enterprise Architect but am also curious about what is available in VS 2010. I'm not looking for responses about how much you hate Microsoft tools or love mircosoft tools, but more for answers about how useful VS2010 arc tools are for you.

  • How to do bulk update of views?

    - by Shaul
    My database has about 30 views, most of which have a reference to another database on this server (call it DB1). Now, without going into the reasons why, I need to update all those views to DB2, also on the local server. I would hate to have to do this manually on each view. Is there some SQL query I can run that will replace all occurrences of the string 'DB1' with 'DB2' in all my views?

  • Rules regarding iPhone apps

    - by iphone newbie
    iphone dev has this rule for iphone developers Be certain that the items you offer for purchase do not contain, or relate to, pornography, hate speech, defamation, or gambling (simulated gambling is acceptable). But how come there are apps in the app store such as iBetMate, which, in fact, allows users to gamble? Is there a clause or something that I missed in Apple's rules?

  • Enable Media Volume Slider in Android application.

    - by user300972
    Some Android programs trigger the "media volume" slider when the hardware volume up/down buttons are pressed. My application seems to set the ringer volume when the hardware buttons are pressed. How would I enable the media volume slider? I would hate for users to have to go into their settings to change the media volume when they use my application.

  • A simple, clean web layout

    - by Shaun_web
    Ok, so I hate CSS/HTML graphic design... What do you guys recommend as a sample template or website that you think has great CSS and html layout? From my past experience it's best to get a page that has a white background and little dependency on graphics -- that's clean, and easy to modify ;-).

  • Java projects without swing

    - by Jeff Home
    I'm quite familiar with Java and I would like to work on a project on my free time but for some reason, I just hate having to work with swing. I'm wondering what kind of Java technologies are available out there that I can use for starting a project. Thank you.

  • Implementing a 30 day time trial

    - by svintus
    Question for indie Mac developers out there: How do I implement a 30-day time trial in a non-evil fashion? Putting a counter in the prefs is not an option, since wiping prefs once a month is not a problem for an average user. Putting the counter in a hidden file somewhere sounds a bit dodgy - as a user I hate when apps sprinkle my hard drive with random files. Any ideas?

  • Agile Testing Days 2012 – Day 1 – The birth of the #unicorn…

    - by Chris George
    Still riding the high from the tutorial day, I arrived at the conference venue eager to get cracking with the days talks. The opening Keynote was “Disciplined Agile Delivery: The Foundation for Scaling Agile” presented by Scott Ambler. The general ideas behind the methodology such as not re-inventing the wheel, and being goal driven, not prescriptive in how you work certainly struck chords with how we are trying to work in my team. Scott made some interesting observations about how scrum is quite prescriptive and is this really agile? I agreed with quite a few of his points on how what works for one team may not work for another. How a team works should be driven by context and reflection, not process and prescription. However was somewhat dubious about some of the statistics he rolled out towards the end. However, out of this keynote was born something that was to transcend this one presentation. During the talk, Scott mentioned on more than one occasion “In the real world”, and at one point made reference to people living in the land of unicorns and rainbows. The challenge was then laid down on twitter for all speakers to include a unicorn in their presentations… and for the most part this happened! It became an identity for this years conference, and I’m sure something that any attendee will always associate with Agile Testing Days 2012! Following this keynote, I attended “Going agile with Automated GUI Testing – Some personal insights” by Jan Zdunek from codecentric on the vendor track. My speciality is test automation, and in particular GUI testing, so this drew me to this talk more than the others. Thankfully, it was made clear from the very start that this was not peddling any particular product (even though it was on the vendor track), and Jan faithfully stuck to that. Most of the content was not new to me, but it was really comforting to hear someone else with very similar experiences to my own. In particular, things like how GUI testing is hard and is not a silver bullet; how record & replay is NOT a good thing to do (which drew a somewhat inflammatory tweet from an automation company when I tweeted that!). Something that I have started hearing around the place, and has certainly been murmuring at work is to push more of the automation coding onto the developers. After all they are the coding experts. I agree with this to a degree, but I personally enjoy coding and find it very rewarding doing so, therefore I’d be reluctant to give it up. I think there are some better alternatives such as pairing with a developer. Lastly, Jan mentioned, almost in passing, that we should consider virtualisation for gui testing for covering configuration combinations. On my project we’ve been running our win32/.NET GUI tests in cloud virtualisation for a couple of years now… I really should write about that! After lunch the second keynote of the day was by Lisa Crispin and Janet Gregory,”Myths about Agile Testing, De-Bunked”. It started off well… with the two ladies donning Medusa style head bands whilst they disbanding several myths about agile testing! I got the impression that it was perhaps not as slick as they would have liked, but then Janet was suffering with a very sore throat so kept losing her voice. Nevertheless, the presentation was captivating, and they debunked several myths such as : “Testing is dead”, “Testers must write code”, “Agile teams always deliver faster”. I didn’t take many notes for this because it was being recorded, but unfortunately the recordings have not been posted yet so I’ll write more about this when they are. The TestLab was held during a somewhat free for all time during most of the afternoon. It looked intriguing and proved to be one of the surprising experiences of the conference for me. Run by James Lyndsay and Bart Knaack, it consisted of a number of ‘stations’ that offered different testing problems. I opted for testing a mathematical drawing app call Geogebra, the task being to pair up and exploratory test it. After an allotted time, we discussed issues we’d found and decided if we wanted to continue ‘playing’ to which we all agreed! It was fun! The last track talk of the day was “Developers Exploratory Testing – Raising the bar” by Sigge Birgisson. One of the teams at Red Gate have tried Dev or Team exploratory testing a couple of times, and I was really interested to go to the presentation that prompted that. I was not disappointed! Sigge gave a first class presentation, and not only explained what DET was all about, but also how to go about implementing it. Little tips like calling it a ‘workshop’ rather than ‘testing’ I can really see working! Monday evening saw the presentation of the award for the Most Influential Agile Testing Professional Person go to a much deserved Lisa Crispin. The evening was great, with acrobatics, magic and music. My Takeaway Triple from Day 1:  Some of the cool stuff that was suggested in the GUI Testing talk, we are already doing. I should write about that! Testing is not dead! Perhaps testing will become more of a skill than a specific role, but it is certainly not dead. Team/Developer exploratory testing… seems like a no-brainer assuming you have a team who is willing.  Day 2 – Coming soon…

  • when using exchange 2010 it complains of not talking to Information Store service on exchange 2007

    - by ChrisMuench
    I am attempting to do an upgrade in my org from exchange 2007 to exchange 2010. I moved all the mailboxes and made sure my certificates were setup in exchange 2010. I then changed my ip forwarding rules to forward mail to my exchange 2010 box. I can receive email. I then powered off my exchange 2007 server. However now when I open my exchange 2010 console it is complaing of not being able to talk to the Information Store service on my exchange 2007 server. What is up? do I have to tell exchange somewhere "who" is the new exchange server? I'm confused. I hate it when software does it automatically. I want to force it to do something.

  • Replacement mouse "feet"?

    - by Jeff Atwood
    The plastic skid pad "feet" on the bottom of my Logitech G9 mouse (which I love!) are getting rather worn down -- to the point that the outer shell of the mouse scrapes on the mousepad a bit. I've had the mouse for about ~2 years now so it does get a lot (I mean lot of use). But, I hate to buy a new mouse when I only need replacement "feet". Where can I obtain replacement mouse feet? Is this even possible?

  • Since updating to today's version of Skype on Win8, Skype won't even log in

    - by Warren P
    I am using the desktop (win32 not appstore) Skype on Windows 8. I accepted an auto-update today which now will not let me log into skype at all. I wiped out the AppData\Roaming\Skype folder because that's how you get Skype back in the past when it has gone stupid, but that didn't help either. I do not get any error message, just the circular progress indicator that lasts forever. (Okay, so far it's been 30 minutes. It may eventually time out yet.) Other ideas please? I tried the Windows 8 App Store Skype app (WinRT), which I hate, I guess I'll go back and install that for now. Update Skype 6.0.126 seems to be completely broken on my Win8 machine.

  • Windows Vista SP2 and DEP Woes for Older Program

    - by neezer
    I have a database client (4D 2004 Client... which, for the record, I vehemently hate but am forced to use because our company is still running this) that I'm trying to run in Windows Vista SP2. I've added the program to the DEP Exceptions list (per a 4D tech article detailing this problem... sorry, can't find the link now) and restarted the computer, but every time I try to log-in to our remote database, the program is shut down by Vista, citing a DEP event. And yes, I have restarted the computer several times, so the new DEP settings should be in effect. I'm a bit confused at this since I specifically added the 4DClient.exe to the DEP Exception list! I realize that very few (if any) of you might have this exact problem with this exact program, but can anyone shed light on the fact that DEP still seems to be enabled for a program that I've specifically added to the DEP exception list?!?

  • USB to LPT adapter?

    - by Dave
    I'm bummed out, pretty much all of our computers here lack parallel ports. I have an EETools ChipMax programming tool that has one of the old-school Centronics connectors on the back. I figured that someone must make a USB to LPT adapter. Sure enough, I found one from iogear, the GUC1284B that is a USB to Parallel Printer cable. Note the boldface on the Printer. It must connect to a printer -- it isn't some generic USB to parallel interface, unfortunately. Does anyone here know of an adapter that works for parallel devices that aren't printers? I'd hate to have to buy a USB version of the ChipMax when I don't need to use it very much.
