  • How to check if location services are enabled for a particular app prior to iOS 4.2?

    - by NobleK
    Hello How can I check if the user has allowed location for mu app? Normally I would use authorizationStatus method of the CLLocationManager class, but it is only available in iOS 4.2 and newer. Is it possible to achieve this somehow while still using SDK 4.2, so that the app can still run on devices with older versions of iOS, or do I have to downgrade the SDK? And along the same line, I need a similar alternative for the locationServicesEnabled method prior to iOS 4.0. Thanx

  • Replacement for java.util.zip for streaming usage?

    - by evilfred
    java.util.zip sucks for stream compression. The longer you leave an Inflator/Deflator open without calling end(), the more native memory it uses up. This is a known issue: http://bugs.sun.com/view_bug.do?bug_id=4797189 which nobody seems to care about fixing. What is a good alternative? Preferably one that is free and is still actively supported by its developers.

  • MySQLDump without locking the tables

    - by Raul Singahn
    It seems that if you have many tables, you can only perform a MySQLDump without locking them all, otherwise you can an error. What are the side effects of performing a MySQLDump without locking all the tables; Is the DB snapshot I get this way, consistent? Do I have any other alternative for getting a backup of a MySQL DB with many tables?

  • python: html writer?

    - by Bin Chen
    With jquery it's very easy to insert some element inside another element using the selector technology, I am wondering if there is any python library that can do things similar with jquery, the reason is I want server side python program to produce the static pages, which needs to parse the html and insert something into it. Or other alternative, not in python language at all? EDIT: To be clear, I want to use python to write below program: h = html.parse('temp.html') h.find('#idnum').html('<b>my html generated</b>') h.close()

    What is a standardized alternative to window.location.href function? I was checking on w3schools.com that it is implemented in all major browsers so there's no problem but I'm rather curious how to do that properly. From here is the statement that the function is not standardized: https://developer.mozilla.org/en/DOM/window.location Thanks!

  • non contiguous String object C#.net

    - by Kazoom
    By what i understand String and StringBuilder objects both allocate contiguous memory underneath. My program runs for days buffering several output in a String object. This sometimes cause outofmemoryexception which i think is because of non availability of contiguous memory. my string size can go upto 100MBs and i m concatenating new string frequently this causes new string object being allocated. i can reduce new string object creation by using Stringbuilder but that would not solve my problem entirely Is there an alternative to a contiguous string object?

  • How to build a client to Google wave

    - by Haggai
    Hi, By looking at current Google wave APIs, I can't find a way to create an alternative client. It's not a robot or gadget, and the embed API is very slim. Nevertheless, I do see some clients out there - such as Waver and Waveboard. How do they do it ? is it based on XMPP ?

  • Example of moving from MySQL to NoSQL?

    - by OverTheRainbow
    Hello, For a Facebook-like site, ie. which is write-intensive and delivers user-customized pages, I'd like to build a prototype to investigate whether the document-centric NoSQL architecture would be a good alternative to sharding and reduce the load on the single master (+ multiple slaves) that we currently use and is the bottleneck. Does someone know of a good article that would give actual, simple examples of going from a relational layout in MySQL to a NoSQL layout? Thank you.

  • Is there an ActiveRecord equivalent to using a nested subquery i.e. ... where NOT IN(select...) ?

    - by Snorkpete
    I have 3 models: Category, Account, and SubAccount The relations are: Accounts has_many :sub_accounts Categories has_many :sub_accounts I wanted to get a list of all Categories that are not used by a given account. My method in the Category model currently looks like: class Category < ActiveRecord::Base def self.not_used_by(account) Category.find_by_sql("select * from categories where id not in(select category_id from sub_accounts where account_id = #{account.id})") end end My question is, is there a cleaner alternative than using SQL? NB. I am currently using Rails 3(beta)

  • create menus in command line

    - by Miles Rout
    How can one create menus in the command line program? I've tried stuff like: cin input; switch (input) { case (1): // do stuff case (2): // ... } but then I've had the problem of sub-menus, and going back to the same menu, etc. The first program I wrote (apart from exercises) that tried to use the switch idea for the menus had goto statements because the alternative was heaps of (at the time) complicated loops.
