• Python: When passing variables between methods, is it necessary to assign it a new name?

  - by Anthony

  I'm thinking that the answer is probably 'no' if the program is small and there are a lot of methods, but what about in a larger program? If I am going to be using one variable in multiple methods throughout the program, is it smarter to: Come up with a different phrasing for each method (to eliminate naming conflicts). Use the same name for each method (to eliminate confusion) Just use a global variable (to eliminate both) This is more of a stylistic question than anything else. What naming convention do YOU use when passing variables?

• what the best and simplest way to find out whether a volume need defrag?

  - by r9r9r9

  I am writing a application that monitor the system's health, user should know when they need to defrag the volumes. What I am thinking is calling the "defrag.exe /A" then analyze the output result to see whether it contains "You do not need to defragment this volume." But it's slow and very bad, I fount that the "Analyze" is really quick on the MyDefrag.exe. Anyone could tell me what's the best and simplest way?

• Store password temporarily in memory

  - by Nils

  Hello, I'm looking for a way in an Android application to store a password within the memory as long as the application is running (cf. different activities). I was first thinking about the SharedPreferences, but then it's saved in the flash memory, which isn't that good for a password, I guess. I'm unsure, what's the best way. What would you recommend me?

  - by voyager

  Do you know any application, the more interesting/useful the better, to introduce a new person to Python language and the Python code style, but not necessarily to OO programing, so as to learn the subtleties and idioms of the language and surrounding community? I'm thinking along the lines of people that has worked with JavaScript, Java or .NET, and already have a strong hold of OO concepts.

• Responding to preference updates in Android

  - by hgpc

  I am calling a PreferenceActivity from another activity and then updating the application state (ie: changing the font size) on onActivityResult, based on the preference changes. I was thinking it would be better to put the state update logic in the PreferenceActivity. That way I don't have the duplicate the logic in each activity that calls the PreferenceActivity. What's the best or correct way to do this?

• What programming shortcuts do you end up regretting or backing out?

  - by bryanjonker

  I saw this question and it reminded me of AutoGenerateColumns in the old DataGrid. The few times I've used them, I ended up backing it out because I needed data formatting past the standard "spit out the Data Source columns." Likewise, with toggle, it sounds like it would save time, but then you end up needing to keep track of state or something else, and you rewrite the code accordingly. Are there things that you end up using thinking it will save you time, but end up backing out because it doesn't do what you need?

• Where a developer can sell / donate his time?

  - by kyrisu

  Recently business isn't good and was wondering what are your favourite places where you can sell your time working on a projects (you get specification / idea - you crank code - you get paid :) ) (I don't mean selling your own apps, just working for someone else) or where you can donate your time (you get specification - you crank code - you feel good :D) (I've heard about cranking code on weekends for charities in US but I'm from Poland so I was thinking about something not location specific)

  I was wondering, since things like display lists are now deprecated, I'm thinking the GLU polygon tesselator is probably also deprecated. What is the new and correct way of creating concave or complex polygons and complying with the new GL 3 standard? Thanks.

• One Account with many users authentication in rails

  - by Cristian

  Which approach would you recommend to the following issue: My app needs to have an account with several users inputting tasks on the same account. Only one of the users (the one that opened the account) will have admin privileges. Im thinking on using Authlogic for authentication and CanCan for determining user privileges. The point is that I'd like the User that opened the Account to be admin by default being him the only one to be able to generate other Users for his account with a different privileges. Thanks, CD

• Where does the AccountController in Asp.Net MVC 2 store its data?

  - by JLago

  I'm creating a website using ASP.NET MVC 2 and I'm thinking of using the default AccountController and Views to take care of the Users. The only problem is that, for all the rest, I'm using a Postgres database. Is there a way to link The account controller to a User class defined by me? I'm using Nhibernate to connect to the database, so I'll have a User class with whatever fields necessary. Thanks very much.

• C#: Perform Operations on GPU, not CPU (Calculate Pi)

  - by Alex

  Hello, I've recently read a lot about software (mostly scientific/math and encryption related) that moves part of their calculation onto the GPU which causes a 100-1000 (!) fold increase in speed for supported operations. Is there a library, API or other way to run something on the GPU via C#? I'm thinking of simple Pi calculation. I have a GeForce 8800 GTX if that's relevant at all (would prefer card independent solution though). Any hints are appreciated!

• What potential do you see in Silverlight?

  - by Cyril Gupta

  Silverlight has been available since quite some time, and Silverlight 2 allows .Net programming on the front-end. I've been thinking about the apps that I can make using Silverlight, but I can't decide if I should go for development in Silverlight because i am still concerned about accessibility and acceptance. What potential do you see in Silverlight judging from the current trends, and what do you think Silverlight will be used for in the coming years?

• jquery-like HTML parsing in Python?

  - by Roy Tang

  Is there any Python library that allows me to parse an HTML document similar to what jQuery does? i.e. I'd like to be able to use CSS selector syntax to grab an arbitrary set of nodes from the document, read their content/attributes, etc. The only Python HTML parsing lib I've used before was BeautifulSoup, and even though it's fine I keep thinking it would be faster to do my parsing if I had jQuery syntax available. :D

• License plate recognition

  - by WowtaH

  As a side-project I'm trying to create an app that scans license plates from passing cars from my living-room window. I have hooked up a high resolution camera to my system to capture (moving) images into my c# app. Now all I need is a way to interpret these images into something readable. I´m thinking about some sort of OCR-solution that is fast/accurate enough for moving images. Hope you can give me some direction!
