• Android Persistent ContentObserver

  - by Lucas Stark

  Are content observers persistent in Android? If I create a content observer in an activity, will that observer continue to run until I remove the observer. Basically I am creating a service for SMS, where on receive and on send I post the SMS out to a web service, so I can check my messages with out having my phone.

• idlj Ignoring "#pragma prefix"

  - by Benny

  I have an IDL file that has a "#pragma prefix" directive, but whenever I use idlj to build the Java code, it ignores this and generates an _id without the prefix specified. This is a big problem because when _is_a is used, it always returns false, since my generated code does not contain the expected prefix. Please help! Thanks in advance!

• SHA1 hash question

  - by phenevo

  Hi, I have this method to hash a string: byte[] buffer = enc.GetBytes(text); SHA1CryptoServiceProvider cryptoTransformSHA1 = new SHA1CryptoServiceProvider(); string hash = BitConverter.ToString( cryptoTransformSHA1.ComputeHash(buffer)).Replace("-", ""); return hash; My question is: Is the resulting hash always the same for the same string? I hashed a string a couple of days ago and it seems that it now resulted in another hash, but i'm not sure.

• Long overdue (for me) question about disposing managed objects in .Net, VB.Net, C#

  - by Jules

  I can't believe I'm still confused about this but, any way, lets finally nail it: I have a class that overrides OnPaint to do some drawing. To speed things up, I create the pens, brushes etc before hand, in the construtor, so that OnPaint does not need to keep creating and disposing them. Now, I make sure that I always dispose of such objects, but I have the feeling I don't need to because, despite the fact they implement IDisposable, they're managed objects. Is this correct?

• Does the asp.net RoleManager really cache the roles for a user in a cookie if so configured?

  - by Ralph Shillington

  In my web.config I have the Role Manager configured as follows: <roleManager enabled="true" cacheRolesInCookie="true" cookieName=".ASPROLES" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" cookieProtection="All"> however in our custom RoleProvider it would seems that the GetRolesForUser method is always being called, rather than as I would have expected, the RoleManager serving up the roles from its cookie. We're using something like to get the roles for a user: string[] myroles = Role.GetRolesForUser("myuser"); Is there something that I'm missing in the configuration, or in the use of the RoleManager Thanks in advance

• using htmlpurifier for input or output escaping/filtering

  - by user214545

  I am processing a user input from the public with a javascript WYSIWYG editor and I'm planning on using htmlpurifier to cleanse the text. I thought it would be enough to use htmlpurifier on the input, stored the cleaned input in the database,and then output it without further escaping/filtering. But I've heard other opinions that you should always escape the output. Can someone explain why I should need to cleans the output if I'm already cleaning the input?

• Is it possible to prevent just horizontal scrolling when overflow-x is hidden?

  - by Andrew LeClair

  I have a web page that has content which extends past the right edge of the browser window. I set overflow-x: hidden on <body> to turn off the bottom scrollbar, but I can still scroll horizontally with the trackpad, which is not what I want. Is there any way to prevent the browser from scrolling horizontally? As a side note: Safari 4.0.4 only scrolls horizontally sometimes, and the scrolling feels "sticky" and "jumpy," whereas Firefox always smoothly scrolls horizontally.

• Where Googlebot starts crawling?

  - by Nirmal

  Say if I register a domain and have developed it into a complete website. From where and how Googlebot knows that the new domain is up? Does it always start with the domain registry? If it starts with the registry, does that mean that anyone can have complete access to the registry's database? Thanks for any insight.

  - by Dinah

  There's always skepticism from non-programmers when honest developers learn the techniques of black hat hackers. Obviously though, we need to learn many of their tricks so we can keep our own security up to par. To what extent do you think an honest programmer needs to know the methods of malicious programmers?

• Java RegEx find, except when between quotes

  - by user1833511

  I need a Java RegEx to split, or find something in a string, but exclude stuff that's between double quotes. What I do now is this: String withoutQuotes = str.replaceAll("\\\".*?\\\"", "placeholder"); withoutQuotes = withoutQuotes.replaceAll(" ",""); but this doesn't work nice with indexOf, and I also need to be able to split, for example: String str = "hello;world;how;\"are;you?\"" String[] strArray = str.split(/*some regex*/); // strArray now contains: ["hello", "world", "how", "\"are you?\"] quotes are always balanced quotes can be escaped with \" Any help is appreciated
