Today I setup a wiki for the all the common source code we created and/or use at b2cloud when developing apps, and I thought I would take you through the steps to creating one. Now the first things first, given that you are on a fairly typical Apache/PHP/MySQL setup (which most hosting providers are) then
Objective C categories are great for extending classes, however if you want to override methods then you’re going to have some problems as you can no longer call the method on your original class owns, usually breaking a lot of functionality the higher up the class food chain you travel (try this on NSObject‘s init, return nil). If you called the same method on self you would end up with an infinite loop, and calling super will skip the original class completely.
Most businesses and organisations would have a Facebook page by now. Whether they have the discipline to update it regularly, posting interesting content and interacting with users is another story.
Apple’s (AAPL.O) figurehead, the pinnacle of their publicity efforts and the man we (and investors) saw as the innovator and industrial leader in the modern technology world was Steve Jobs. Who steers the ship when he is no longer around?
You rarely get a second chance in the App world, so don’t bother releasing Apps that aren’t revolutionary. In reality many Apps don’t make life any easier for the user, nor do they provide anything innovative.
One of the most exciting developments over the last couple of years for web design has been the ability to include custom font choices. We can finally spice up designs without having to create images out of text. But what are the pros & cons of web font technologies and where do we still need to advance with the technology.
Bridging images in a UIImage into other API’s such as OpenCV can be painful, however there is 1 format that every image processing library understands, and that is the format of “raw”, where each pixel is represented as an unsigned byte in an array. Unless you are dealing with video formats, which can use YUV,
Autofill makes it easy to access regularly visited sites that require a password. When you go back you see your username and password conveniently filled in for you, and because the password is stared out nobody can get this, right? Wrong. If somebody opens up the autofilled page they can very easily use Javascript to reveal the contents of the password field to them.
So you’ve come up with a great new business idea. Your (insert: widget, website, app) has never been done before, everyone will be using it, your market is the whole world blah blah blah. WRONG.
I typically purchase magazines when I travel as they have a great selection at the airport, and I have ample time to read them cover to cover on the plane. Last week I was in transit to New Zealand and splashed out $18 for a copy of this months Harvard Business Review with cover headline “Build a culture of trust and innovation – COLLABORATE”. This is very topical to our team at b2cloud, colleagues and clients.
