JVM Minimal Survival Guide – Hadi Hariri
When you come to a new platform, from a similar one, you often spend time trying to get up to speed with concepts/frameworks you know, but you don’t know, because they go by a different name, a different approach. It’s time-consuming and sometimes even frustrating. This guide is an attempt to help others avoid some of those newbie questions.

Bacon.js - Functional Reactive Programming library for JavaScript
A small functional reactive programming lib for JavaScript. Turns your event spaghetti into clean and declarative feng shui bacon, by switching from imperative to functional. It's like replacing nested for-loops with functional programming concepts like map and filter. Stop working on individual events and work with event-streams instead. Transform your data with map and filter. Combine your data with merge and combine. Then switch to the heavier weapons and wield flatMap and combineTemplate like a boss. It's the _ of Events. Too bad the symbol ~ is not allowed in Javascript.

So, the evidence and discussion here are anecdotal, not actually reviewed for errors, consistency, writing style, syntactic and semantic errors, duplicates, or consistency.

Node.js Security Checklist | @RisingStack
Security - the elephant in the room. Everyone agrees that it is very important but few takes it seriously. We at RisingStack want you to do it right - this is why we have put together this checklist to help you guide through the must have security checks before your application is enabled to thousands of users/customers.

Most of these items are general and applies to all languages and frameworks not just Node.js - however some of the tools presented are Node.js specific. You should also check our introductory Node.js security blogpost, or if you are just getting started with Node.js, our first chapter of Node Hero.

Building a scalable Node.js Express app – Gerard Rovira – Medium
Most Node.js tutorials, which none of them are to blame for, focus on the content: getting certain libraries / frameworks working. To make it easier for the readers who are new to them they are often presented the most simple solutions.

Whilst these solutions suit most of the times for small to medium projects, large applications tend to require far more abstraction, which is what we’ll be analyzing next.

(How to Write a (Lisp) Interpreter (in Python))
This page has two purposes: to describe how to implement computer language interpreters in general, and in particular to show how to implement a subset of the Scheme dialect of Lisp using Python. I call my language and interpreter Lispy (lis.py). Years ago, I showed how to write a Scheme interpreter in Java as well as one in Common Lisp. This time around the goal is to demonstrate, as concisely and accessibly as possible, what Alan Kay called "Maxwell's Equations of Software."
Why does this matter? As Steve Yegge said, "If you don't know how compilers work, then you don't know how computers work." Yegge describes 8 problems that can be solved with compilers (or equally with interpreters, or with Yegge's typical heavy dosage of cynicism).

The tool is very simple: it allows you to create a new project structure for any framework or library for which the tool has a template. You can even contribute templates by sending pull requests to this GitHub project or publishing the packages to the relevant Bintray repository (more info available below).

Falsehoods programmers believe about time
I have repeatedly been confounded to discover just how many mistakes in both test and application code stem from
misunderstandings or misconceptions about time. By this I mean both the interesting way in which computers handle time, and the fundamental gotchas inherent in how we humans have constructed our calendar – daylight savings being just the tip of the iceberg.

In fact I have seen so many of these misconceptions crop up in other people’s (and my own) programs that I thought it would be worthwhile to collect a list of the more common problems here.

Writing a Domain-Specific Language in Ruby
A Domain-Specific Language, or DSL, is “a programming language of limited expressiveness focused on a particular domain”. It makes tasks in its domain easier by removing extraneous code for a particular task and allowing you to focus on the specific task at hand. It also helps other people read the code, because the purpose of the code is so clear.

Here’s a little Internal DSL in Ruby:

Acing the technical interview
If you want to get a job as a software witch, you’re going to have to pass a whiteboard interview. We all do them, as engineers–often as a part of our morning ritual, along with arranging a beautiful grid of xterms across the astral plane, and compulsively running ls in every nearby directory–just in case things have shifted during the night: the incorporeal equivalent of rummaging through that drawer in the back of the kitchen where we stash odd flanges, screwdrivers, and the strangely specific plastic bits, the accessories, those long-estranged black sheep of the families of our household appliances, their original purpose now forgotten, perhaps never known, but which we are bound to care for nonetheless. I’d like to walk you through a common interview question: reversing a linked list.

five-essential-phone-screen-questions - steveyegge2
I've been on a lot of SDE interview loops lately where the candidate failed miserably: not-inclined votes all around, even from the phone screeners who brought the person in initially.

It's usually pretty obvious when the candidate should have been eliminated during the phone screens. Well, it's obvious in retrospect, anyway: during the interviews, we find some horrible flaw in the candidate which, had anyone thought to ask about it during the phone screen, would surely have disqualified the person.

But we didn't ask. So the candidate came in for interviews and wound up wasting everyone's time.

ten-great-books - steveyegge2
I've tried to read more lately -- where "lately" is maybe the past 2 years -- in an attempt to learn things that I didn't know much about before.

O'Reilly books seem to be the best way to learn about any new technology, because Tim understands that people prefer books that are accessible. I.e., books you can read and understand the first time around, and they don't presuppose a lot of esoteric knowledge. So when I need to learn the latest Algol-family programming language, or Adams-family distributed-computing protocol, or Lisp-family XML technology (Oh no! Now I've gone and let the cat out...), O'Reilly is definitely the way to go.

But for all their great titles, O'Reilly shies away from math, computer science, engineering, general science, and other such impractical nonsense, perhaps because it doesn't sell well. So when I want to learn about something useful but difficult, I need to brave the scary territory of "other publishers".

Butterick’s Practical Typography
But ty­pog­ra­phy can op­ti­mize your writ­ing. Ty­pog­ra­phy can cre­ate a bet­ter first im­pres­sion. Ty­pog­ra­phy can re­in­force your key points. Ty­pog­ra­phy can ex­tend reader at­ten­tion. When you ig­nore ty­pog­ra­phy, you’re ig­nor­ing an op­por­tu­nity to im­prove the ef­fec­tive­ness of your writing.

And isn’t that why you write? To have an ef­fect on read­ers? To move them, to per­suade them, to spur them to action?

If so, then you should want what ty­pog­ra­phy has to of­fer. Best of all, it’s fast and it’s easy. Un­like, say, learn­ing to be a bet­ter writer.

mustache Template Reference
Mustache can be used for HTML, config files, source code - anything. It works by expanding tags in a template using values provided in a hash or object.

We call it "logic-less" because there are no if statements, else clauses, or for loops. Instead there are only tags. Some tags are replaced with a value, some nothing, and others a series of values. This document explains the different types of Mustache tags.

mustache/mustache: Logic-less Ruby templates.

For a list of implementations (other than Ruby) and tips, see http://mustache.github.io/.
