  • Python `if x is not None` or `if not x is None`?

    - by orokusaki
    I've always thought of the if not x is None version to be more clear, but Google's style guide implies (based on this excerpt) that they use if x is not None. Is there any minor performance difference (I'm assuming not), and is there any case where one really doesn't fit (making the other a clear winner for my convention)?* *I'm referring to any singleton, rather than just None. ...to compare singletons like None. Use is or is not.

  • Check checkbox checked property using jQuery

    - by Prasad
    I need to check the checked property of a checkbox and perform an action based on the checked property using jQuery. For example, if the age checkbox is checked, then I need to show a textbox to enter age, else hide the textbox. But the following code returns false by default: if($('#isAgeSelected').attr('checked')) { $("#txtAge").show(); } else { $("#txtAge").hide(); } How do I successfully query the checked property?

  • jQuery - Set min-height of div

    - by Kenny Bones
    This is probably really easy for most of you. But I'm in need of a small snippet that looks up the current height of a div (the div has a dynamic height based on the content inside it) and then set that value in the css class's min-height value. Basically what this means is that I want this container to have it's min-height to be the exact same value as it's current height. This is probably a quick one :)

  • Unique text field in MySQL and php

    - by Jonathan
    I've created a salt using; md5(rand(0,10000000)); (there is probably a better way?) There doesn't seem to be possible to make a text field unique in MYSQL. So how do I check if the salt has already been used for a previous user? Or should I generate the salt based on the current date/time? as it is impossible for 2 users to register at exactly the same time correct?

  • Increment an index that uses numbers and characters

    - by Martin
    I have a string based code that can be either two or three characters in length and I am looking for some help in creating a function that will increment it. Each 'digit' of the code has a value of 0 to 9 and A to Z. some examples: the first code in the sequence is 000 009 - next code is - 00A 00D - next code is - 00E AAZ - next code is - AB0 the last code is ZZZ. Hope this makes some sense.

  • Automated incremental backups from Plesk on Centos to Amazon S3

    - by ChrisS
    Hi, I've done a far bit of research on this via Google and there seems to be quite a few ways of possibly doing this. I'm looking to incrementally backup new and updated files in two directories on my Plesk run Centos 5.2 server: /backups and /var/www/vhosts (preferable only httdocs within each vhost) Has anyone got some great feedback from using the various solutions - seems to be various Java, Perl and Ruby based solutions out there. Many thanks, Chris

  • Visual Basic and C++

    - by Hamdy Elgammal
    Hello there, I was reading a little into Visual Basic and it seemed a rather simple way to implement some GUI...So I was looking for a way to interface my C++ code to a Visual Basic snippet of code. For example, receive input from a Visual Basic app and send it over to C++ code to continue the logic of the program based on the input of that event.

  • What is the best way to implement a Server-Client connection between an iPad and multiple iPhones?

    - by Infinite
    Based on a college-project I'm trying to realize a relatively simple game (Poker) where an iPad acts as Server and multiple iPod-Touchs connect to it as Clients. Gamekit seems to drop out, since those old ipod-touch-devices don't have bluetooth-support. Are there already some Frameworks out there simplifying the process, or do I have to fall back on TCP-Streaming-Sockets and implement it myself?

  • MVC alternatives: examples of MVA & AVC?

    - by Phillip Oldham
    I'm interested in learning about the alternative patterns to Model-View-Controller, specifically the Model-View-Adapter and Application-View-Controller patterns. Google results tend to be either a high-level overview or Java-based. Can anyone either provide, or point me to, an example of these patterns in either PHP, Python or JavaScript?

  • Amazon API library for Python?

    - by Kevin
    What Python libraries do folks use for querying Amazon product data? (Amazon Associates Web Service - used to be called E-Commerce API, or something along those lines). Based on my research, PyAWS (http://pyaws.sourceforge.net/) seems okay, but still pretty raw (and hasn't been updated in a while). Wondering if there's an obvious canonical library that I'm just missing.

  • What's the best CDN for image hosting on a high-volume web site?

    - by Mike
    Akamai is way too expensive. Photobucket is not reliable. Is there a great content delivery network that I can use just to host my images? We deploy images programmatically via FTP, so there is some programming behind the scenes. Having some sort of reporting about the reliability of the service, whether it's raw logs files or a web-based admin screen that shows http errors, would also be important. Has anyone worked with edgecast?

  • Declare java enum with a String array

    - by chama
    I'm trying to declare an enum type based on data that I'm retrieving from a database. I have a method that returns a string array of all the rows in the table that I want to make into an enumerated type. Is there any way to construct an enum with an array? This is what I tried, but from the way it looked in eclipse, it seemed like this just created a method by that name: public enum ConditionCodes{ Condition.getDescriptions(); } Thank you in advance!

    I've been looking at the Stanford University iphone videos on iTunes U. And saw the teacher trying to do something similar to this code but he realised and said it didn't work though I didn't get why: - (IBAction)flashPressed{ if (window.backgroundColor == [UIColor magentaColor]){ window.backgroundColor = [UIColor redColor]; }else { window.backgroundColor = [UIColor magentaColor]; } } Objective-C, windows based application. Not sure what else you need to know.
