A compiler reads the program and translates it completely before the program starts running. In this case, the high-level program is called the source code, and the translated program is called the object code or the executable. Once a program is compiled, you can execute it repeatedly without further translation.

An interpreter reads a high-level program and executes it, meaning that it does what the program says. It processes the program a little at a time, alternately reading lines and performing computations.

programming is a skill that allows a computer scientist to take an algorithm and represent it in a notation (a program) that can be followed by a computer. These programs are written in programming languages.

If problem solving is a central part of computer science, then the solutions that you create through the problem solving process are also important. In computer science, we refer to these solutions as algorithms. An algorithm is a step by step list of instructions that if followed exactly will solve the problem under consideration.

The single most important skill for a computer scientist is problem solving. Problem solving means the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately. As it turns out, the process of learning to program is an excellent opportunity to practice problem solving skills.

Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions.

In this singularity-free world, the future would be bleak for programmers. (Imagine having to cope with hundreds of years of legacy software!)

one level is chosen as the “reference”, and its mean behaviour is represented by the intercept. Each column of the resulting matrix represents the difference between the mean of one level and this reference level

Computer programming and coding skills for children and young people.

As an estimate, for a scoping review of 120 studies, it could take the equivalent of 2to 3 weeks for one person one person’s time for, 2 to 3 weeks to undertake the process of coding studies,including developing and testing a coding tool, although this varies between each review

On the basis of our experience of carrying out scoping reviews, we estimate that it takes between 5 and20 minutes to apply codes to one research abstract, depending on the detail of coding required. However, priorto this process, time is needed to develop a coding tool. This involves: considering what data would inform theresearch questions, and therefore deciding the facets upon which to code, and creating a coding tool that isunambiguous, and both broad and detailed enough to describe the dataset. The tool is often developed usinga sample of data, and examining pre-existing tools.

To enhance that process, you could add the appropriate path to the output file name in this script, and write a shell script that runs this script and then commits/pushes to GitHub, and then schedule that script to run at regular intervals from your computer/server. I'm going to look into adding that functionality to this script, but it's not ready yet.

Programming is not a detail that can be left to ‘technicians’ under the false pretence that their choices will be ‘scientifically neutral’. Societies are too complex

Insisting on the glamour and fun of coding is the wrong way to acquaint kids with computer science. It insults their intelligence and plants the pernicious notion in their heads that you don’t need discipline in order to progress. As anyone with even minimal exposure to making software knows, behind a minute of typing lies an hour of study.

As many universities are being queried by the federal government on how they spend their endowment money, and enrollment decreases among all institutions nationally, traditional campuses will need to look at these partnerships as a sign of where education is likely going in the future, and what the federal government may be willing to finance with its student loan programs going ahead.

Libraries like jQuery are useful because they hide the ugly details of dealing with cross-browser differences in JS engines. But these OO-helper libraries are different: they're going to great lengths to hide the true nature of JavaScript's OO mechanisms, instead masking them in a set of patterns that are more familiar to other languages.

Procedural programming and OOP are not going to get us where we need to go by themselves.

How it’s implemented doesn’t matter at all unless it’s implemented poorly.The only thing that matters in software development is that your users love the software.

The tech skills that people are looking for now

Two performances did seem to transcend the present, with artists sharing music that felt like open-source software to paths unknown. The first, Sam Aaron, played an early techno set to a small crowd, performing by coding live. His computer display, splayed naked on a giant screen, showcasedSonic Pi, the free software he invented. Before he let loose by revising lines of brackets, colons and commas, he typed:#This is Sonic Pi…..#I use it to teach people how to code#everything i do tonight, i can teach a 10 year old child…..His set – which sounded like Electric Café-era Kraftwerk, a little bit of Aphex Twin skitter and some Eighties electro – was constructed through typing and deleting lines of code. The shadowy DJ sets, knob-tweaking noise and fogbank ambient of many Moogfest performers was completely demystified and turned into simple numbers and letters that you could see in action. Dubbed "the live coding synth for everyone," it truly seemed less like a performance and more like an invitation to code your own adventure.

In Silicon Valley, this divide is often explicit: As Kate Losse has noted, coders get high salary, prestige, and stock options. The people who do community management—on which the success of many tech companies is based—get none of those. It’s unsurprising that coding has been folded into "making." Consider the instant gratification of seeing "hello, world" on the screen; it’s nearly the easiest possible way to "make" things, and certainly one where failure has a very low cost. Code is "making" because we've figured out how to package it up into discrete units and sell it, and because it is widely perceived to be done by men.

Without feedback, there are three options: I can believe, without evidence, that I am an awesome programmer.  I can believe, without evidence, that I am a terrible programmer and quit to go do something else.  Or finally, I can believe, without evidence, that I am a terrible programmer somehow successfully pretending to be an awesome programmer.

In programming languages like C++, C# or Java a class usually would be defined in a source code. A class definition file (Desktop.cpp/ Desktop.cs/ Desktop.java) in these languages would be a dumb text definition file fed into a compiler to verify and translate.In an interactive and lively system like Pharo a class could be created like any other object by sending instance creation methods. The reason is simple: in a pure OO environment anything is an object, so even a class is an object. Remember: there are only objects and messages.
