Clean Coder Blog We rule the world. We programmers. We rule the world. We write the rules that make our society work. Think about it; and think about it carefully. It’s certainly true that the Earth turns, the Sun rises, the rain falls, and the tides recede and advance without the aid of software. Without software: Phones don’t ring. We don’t quite understand this yet. Healthcare.gov, Knight Capital, Natwest Bank, and Toyota were wakeup calls; but each time we hit the snooze button and went back to sleep. And if they are smart, it’ll scare the hell out of them. And it should scare the hell out of us too. Imagine what we could do if we were to unite. If we wanted to, if we were willing to organize and plan, there would be no force on the planet that could stop us. Perhaps you think I’m exaggerating? But the fact remains that we programmers are in a position of tremendous power that the people whom we serve do not well understand; and that we hardly understand any better. Think of the military.
6 Steps to Becoming a Software Developer | Zenput Blog Deciding to become a software developer is a great initial step, congrats! The job opportunities are growing quickly and in just about every industry that you can imagine. The best part is that you do not necessarily have to go to a four year university to become a great software developer to lock down one of these jobs. The web has all the resources you'll need to interact, learn, get support and finally find a job as a software developer. 0.

SimpleDateFormat Formats and parses dates in a locale-sensitive manner. Formatting turns a Date into a String, and parsing turns a String into a Date. Time Pattern Syntax The main reason you'd create an instance this class directly is because you need to format/parse a specific machine-readable format, in which case you almost certainly want to explicitly ask for US to ensure that you get ASCII digits (rather than, say, Arabic digits). To specify the time format, use a time pattern string. The number of consecutive copies (the "count") of a pattern character further influences the format, as shown in the table. Fractional seconds are handled specially: they're zero-padded on the right. The two pattern characters L and c are ICU-compatible extensions, not available in the RI or in Android before Android 2.3 (Gingerbread, API level 9). Five-count patterns (such as "MMMMM") used for the shortest non-numeric representation of a field were introduced in Android 4.3 (Jelly Bean MR2, API level 18). Sample Code
Level-Up Your Machine Learning Since launching Metacademy, I've had a number of people ask , What should I do if I want to get 'better' at machine learning, but I don't know what I want to learn? Excellent question! My answer: consistently work your way through textbooks. I then watch as they grimace in the same way an out-of-shape person grimaces when a healthy friend responds with, "Oh, I watch what I eat and consistently exercise." But why textbooks? In this brief roadmap, I list a few excellent textbooks for advancing your machine learning knowledge and capabilities. Also, if you want alternative learning resources, Metacademy is at your disposal as are all of these textbooks. My sister, an artist and writer by trade, asked me how she could understand the basics of data science in a nontrivial way. Expectations: You'll understand some common machine learning algorithms at a high-level, and you'll be able to implement some simple algorithms in Excel (and a bit in R if you get through the entire book).
Java SimpleDateFormat - Convert a Java String to a Date (Java String to Date conversion) By Alvin Alexander. Last updated: Jun 10, 2014 Summary: A Java SimpleDateFormat (date formatting) example, showing how to convert a Java String to a Date. In an earlier example I showed how to use the Java SimpleDateFormat class to convert from a Date to a String, but you can also use the Java SimpleDateFormat class to convert in the opposite direction, from a given Java String to a Date object. SimpleDateFormat - Java String to Date conversion, example source code Here's the source code for a complete Java SimpleDateFormat example that demonstrates how to convert from a given formatted Java String to a Date object: SimpleDateFormat Java String to Date conversion - discussion As you can see from that example, the steps to convert from a given Java String to Date using SimpleDateFormat are: Again, just to drill this point home, the date format we're expecting ("MM/dd/yyyy") must match the format we're given (as it does in "09/22/2009"), otherwise the parse method will throw a ParseException.
Stuff that every programmer should know: Data Visualization If you're a programmer and you don't have visualization as one of your main tools in your belt, then good news, you just found how to easily improve your skill set. Really it should be taught in any programming course.Note: This post won't get you from zero to visualization expert, but hopefully it can pique your curiosity and will provide plenty of references for further study. Visualizing data has two main advantages compared to looking at the same data in a tabular form. The first is that we can pack more data in a graph that we can get by looking at numbers on screen, even more if we make our visualizations interactive, allowing explorations inside a data set. This is useful also because it means we can avoid (or rely less on) summarization techniques (statistics) that are always by their nature "lossy" and can easily hide important details (the Anscombe's quartet is the usual example). What's that? - Good visualizations The main objective of visualization is to be meaningful.
Java SimpleDateFormat example - Convert a Date to a formatted String (Java Date to String conversion) By Alvin Alexander. Last updated: Jun 14, 2014 Summary: This tutorial demonstrates how to use the Java SimpleDateFormat class to convert a Java Date to a formatted String. The Java SimpleDateFormat class provides lets you easily convert (a) between a Java String to a Date or (b) perform the opposite conversion, from a Java Date to a String. In this article we'll at several different ways to convert a Java Date object to a nicely formatted String object, and in another article we'll look at a couple of nice ways for converting in the opposite direction. Our first Java SimpleDateFormat example In our first example, we begin by getting today's date (as a java.util.Date object), and then we'll create a Java SimpleDateFormat object to define the custom format we want for the date after it's converted to a String. Here's the source code for a complete Java SimpleDateFormat example class that demonstrates this custom date formatting approach: yyyy-MM-dd-hh.mm.ss

Open Data Structures How To Motivate Yourself: 3 Steps Backed By Science You make goals… but then you procrastinate. You write a to-do list… but then you don’t follow through. And this happens again and again and again. Why are we so good at thinking of what to do but so terrible at actually doing those things? The problem is you’re skipping an essential step. The Mistake Every Productivity System Makes Productivity systems rarely take emotions into account. We can’t ignore our emotions. And we can’t fight our feelings. Via The Antidote: Happiness for People Who Can’t Stand Positive Thinking: …when experimental subjects are told of an unhappy event, but then instructed to try not to feel sad about it, they end up feeling worse than people who are informed of the event, but given no instructions about how to feel. So what does the unavoidable power of feelings mean for motivation? In their book Switch, Chip and Dan Heath say that emotions are an essential part of executing any plan: Focus on emotions. We need to think to plan but we need to feel to act. Sum Up Tags:
