  Please Steal These webOS Features

When Apple introduced the first iPad in 2010, I bought one immediately. I didn’t know what I’d use it for, but I was sure that I would find some use for it. I never did. I played around with it, wrote some code for it, but eventually stopped using it. I would pick it up from time to time to read something or watch a YouTube movie, but even that was a rare occurrence. I have since picked up an iPad 2, and I’m using it a lot more than the first iPad, but again, I’...

  Python object creation sequence

[The Python version described in this article is 3.x] This article aims to explore the process of creating new objects in Python. As I explained in a previous article, object creation is just a special case of calling a callable. Consider this Python code: class Joe: pass j = Joe() What happens when j = Joe() is executed? Python sees it as a call to the callable Joe, and routes it to the internal function PyObject_Call, with Joe passed as the first argument. PyObject_Call looks at the ty...

  Designing Fun

What is “Fun?”“I’ll know it when I see it.”In 1964, in Jacobellis v. Ohio, the US Supreme Court needed to decide whether the state of Ohio could ban a film it called “obscene”—a concept people understood but were hard-pressed to define. Justice Potter Stewart, in his concurring opinion, wrote: “I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I ...

  Set file permission in Java

Prior to Java 6,  there is no good solution at the Java level to provide file permission management. You need to implement your own native methods or call the Runtime.exec() to invoke the system routine such as chmod in LInux. Since Java 6, Java introduces a set of methods which can be used to set the file permission at Java level. These methods include: File.setReadable(boolean); File.setWritable(boolean); FIle.setExecutable(boolean); File.setReadable(boolean, boolean); File.setWritable(bo...

  One of the Best Bits of Programming Advice I ever Got

Years ago (early 1992), I attached myself to this crazy skunkworks project that was using this weird language called Smalltalk. "Object Oriented" was in its infancy as a "hot" item. High paid consultants. Lots of people laying claim to what this new object religion was all about. This was 5 years before Alan Kay would make the statement "I invented the term 'Object Oriented Programming' and this {Java and C++} is not what I had in mind."Shortly after hooking up with this whacky group with t...

  Audio API in Android development

Mobile devices of the first generation were not capable of playing any sounds except monophonic ringtones. Today any smartphone platform supports playback, record and to some extent manipulation of digital sound, often up to CD quality.Android is no exception to that. Even older 1.5 devices can do a lot of things with digital audio. However, due to lack of guidance, a developer who is doing his first audio feature might miss some of the available API facilities, or might choose the approach that...

  It Should Only Take You a Few Hours...

It sure seems easy to make a table. Anyone can do it, right? Get 1 large flat rectangular piece of wood, 4 equally tall wooden poles, 4 nails and a hammer. Nail the 4 poles to each corner of the flat rectangular bit, and you have a table. Ta daaa! Now ask a carpenter to craft you a table. First they will spend time discussing the purpose and function of the table - indoor or outdoor, kitchen or dining room, for show or heavy use, what load does it need to bear. Then they will determine th...

  User experience distance

Good user experience can narrow the gap between product and users, it can also improve the user efficiency and increase satisfaction and comfort of users. Here we talk about user experience distance with different examples: 1. Floating bubble layer When users need to delete one picture,they click on the "Delete" button, then the floating bubble layer appears to prompt the user to confirm the deletion, users only need to focus on the picture which reduces the visual burden, and also no need to mo...

  Set Theory in C++11

Have you ever felt the need to perform set theoretic operations on types? Not really? Me neither, but I thought it’s a fun thing to try out. So, if you ever feel the need of using type sets, C++11 makes it quite easy to do so. Especially variadic templates allow for a much more condensed syntax compared to type list constructs formerly used. (Disclaimer: This is rather a proof of concept, but maybe somebody comes up with a useful scenario.) Let’s start by d...
