• @ in p4 filename

  - by Denise

  I'd like to script p4 a little. Unfortunately, some of the filenames that we're tracking have "@" in the filename. The filenames are in the form [email protected]. If I try to do something like p4 sync a\@b.xml on a mac (or p4 sync [email protected] on windows) it gives the error: Invalid changelist/client/label/date '@b.xml' Is there another way to escape it that perforce will recognize?

• Safest LAMP encrypt method

  - by Adam Kiss

  Hello, what is PHP's safest encrypt/decrypt method, in use with MySQL - to store let's say passwords? Of course, not for portal purposes. I want to do little password (domain/mysql/ftp...) storage for whole team online, but I don't want really to endanger our clients' bussinesses. Hash can't be used for obvious reasons (Doesn't really make sense to run rainbow tables every time :D). Any idea?

• Whats better query with long where in condition or many small queries?

  - by DCrystal

  Maybe it's a little dumb, but i'm just not sure what is better. If i have to check about 30k rows in db for existanse, what i'd do? #1 - one query select id from table1 where name in (smth1,smth2...{till 30k}) #2 - many queries select id from table1 where name=smth1 Though, perfomance is not the goal, i don't want to go down with mysql either ;) Maybe, any other solutions will be more suitable... Thanks.

• Load large images into Bitmap?

  - by GuyNoir

  I'm trying to make a basic application that displays an image from the camera, but I when I try to load the .jpg in from the sdcard with BitmapFactory.decodeFile, it returns null. It doesn't give an out of memory error which I find strange, but the exact same code works fine on smaller images. How does the generic gallery display huge pictures from the camera with so little memory?

• Can someone explain this 'double negative' trick?

  - by ProfessionalAmateur

  Hello, I am by no means an expert at javascript, but I have been reading Dave Pilgrim's "Dive into HTML5" webpage and he mentioned something that I would like a better understanding of. He states: "Finally, you use the double-negative trick to force the result to a Boolean value (true or false)." function supports_canvas() { return !!document.createElement('canvas').getContext; } If anyone can explain this a little better I would appreciate it!

• Is there a better way to share master pages now that VS 2010 and .Net 4 are out?

  - by Max Schmeling

  I'm trying to find a better way to share a master page than the old method of using Web Deployment Projects and a really nasty master page to share master pages between applications. I would think Microsoft would have given us something a little nicer in 2010, but I haven't found anything. Any ideas?

• MainMenu with Images

  - by j-t-s

  I have a MainMenu in my app and I would like to have little icons relevant to the Item in each menu. But the MainMenu control does not support this. I would use the MenuStrip control, though that is a pretty ugly option in my opinion. Does anybody have any suggestions? Are there any free/open source alt's out there, or would it be easy/possible to implement that feature into the existing MainMenu control?

• Asp.net Mvc - Kigg: Maintain User object in HttpContext.Items between requests.

  - by Pickels

  Hallo, first I want to say that I hope this doesn't look like I am lazy but I have some trouble understanding a piece of code from the following project. http://kigg.codeplex.com/ I was going through the source code and I noticed something that would be usefull for my own little project I am making. In their BaseController they have the following code: private static readonly Type CurrentUserKey = typeof(IUser); public IUser CurrentUser { get { if (!string.IsNullOrEmpty(CurrentUserName)) { IUser user = HttpContext.Items[CurrentUserKey] as IUser; if (user == null) { user = AccountRepository.FindByClaim(CurrentUserName); if (user != null) { HttpContext.Items[CurrentUserKey] = user; } } return user; } return null; } } This isn't an exact copy of the code I adjusted it a little to my needs. This part of the code I still understand. They store their IUser in HttpContext.Items. I guess they do it so that they don't have to call the database eachtime they need the User object. The part that I don't understand is how they maintain this object in between requests. If I understand correctly the HttpContext.Items is a per request cache storage. So after some more digging I found the following code. internal static IDictionary<UnityPerWebRequestLifetimeManager, object> GetInstances(HttpContextBase httpContext) { IDictionary<UnityPerWebRequestLifetimeManager, object> instances; if (httpContext.Items.Contains(Key)) { instances = (IDictionary<UnityPerWebRequestLifetimeManager, object>) httpContext.Items[Key]; } else { lock (httpContext.Items) { if (httpContext.Items.Contains(Key)) { instances = (IDictionary<UnityPerWebRequestLifetimeManager, object>) httpContext.Items[Key]; } else { instances = new Dictionary<UnityPerWebRequestLifetimeManager, object>(); httpContext.Items.Add(Key, instances); } } } return instances; } This is the part where some magic happens that I don't understand. I think they use Unity to do some dependency injection on each request? In my project I am using Ninject and I am wondering how I can get the same result. I guess InRequestScope in Ninject is the same as UnityPerWebRequestLifetimeManager? I am also wondering which class/method they are binding to which interface? Since the HttpContext.Items get destroyed each request how do they prevent losing their user object? Anyway it's kinda a long question so I am gradefull for any push in the right direction. Kind regards, Pickels

• Is there a replacement for Paste.Template?

  - by Jorge Vargas

  I have grown tired of all the little issues with paste template, it's horrible to maintain the templates, it has no way of updating an old project and it's very hard to test. I'm wondering if someone knows of an alternative for quickstart generators as they have proven to be useful.

• Type mismatch: cannot convert from ArrayList<Data> to MyCollection

  - by Tommy

  I've read similar questions here but I'm still a little confused. MyCollection extends ArrayList<MyClass> MyClass implements Data yet this gives me the "cannot convert from ArrayList to MyCollection" MyCollection mycollection = somehandler.getCollection(); where getCollection looks like this public ArrayList<Data> getCollection() So my assumptions are obviously wrong. How can I make this work like I would like it to

• Who use class variables in SOAP calls with Savon?

  - by Steffen Roller

  I'm writing a little client using Ruby and Savon. The interface changed significantly from version 0.7 to 0.8.x. All my calls don't work anymore :-(. How can I pass on a local member variable. Please see the example, @userName and @userPassword are not defined within the block. begin @response = @authentication_svc.request :wsdl, "AuthenticateUser" do http.headers["SOAPAction"] = "AuthenticateUser" soap.body = "#{@userName}#{@passwd}" end rescue Savon::SOAP::Fault = e @last_soap_error = e.message end

• Java weird generic return type

  - by drozzy

  Browsing through Guava libraries I saw this weird signature on a readLines method from Files class: public static <T> T readLines(File file, Charset charset, LineProcessor<T> callback) I know a little bit about generics in java, but this baffled me. What does the double T mean here? And why is the first one in angled brackets?

• What is the correct verb for what programmers do?

  - by bennybdbc

  Sorry if this is a little off-topic, but I never know what word to use when I am searching the internet for articles or tutorials. What I mean is, say I wanted to search for information regarding making a notepad clone, would I search for: "Creating A Notepad Clone" "Building A Notepad Clone" "Making A Notepad Clone" So what I'm asking is basically, is there a definitive term to use, or does it vary depending on the source?

• why do I need the @ for setting variable value

  - by Saad

  I'm a little confused about scope of variables, in ruby I wrote a test program: class Test attr_reader :tester def initialize(data) @tester = data end def getData tester end end puts Test.new(11).getData now this works fine, the attr_reader, but my confusion is that since I've define attr_reader :tester then why can't I go tester = data rather then @tester = data, because when retrieving the data in getData I only have to write tester and not @tester

• Is is possible to have grouped GridView without using CollectionViewSource?

  - by Sergey Aldoukhov

  It is just seems to be a little awkward design to tie a feature to a class instead of interface. Has anybody managed to group GridView without CollectionViewSource? Also a bonus question here: why you have to refer to the CollectionViewSource resource through binding: <GridView ItemsSource="{Binding Source={StaticResource groupedData}}" > instead of <GridView ItemsSource="{StaticResource groupedData}" > ??

• Android Google maps co-ordinates

  - by Scoobler

  I have an app which stores co-ordinates. I am using Google maps to show the location to allow full use of the maps app. I am using the intent call and placing the co-ordinates in the q=xxxxxxxxx,xxxxxxxxx part. This works, however when Google maps shows the location it often finds a point on the road, sometimes a little distance from the actual co-ordinates. Is there a way to get maps to show the actual point?
