Text-Terminal-HOWTO
This document was originally written for real text terminals which were like monitors (with keyboards), but could only display text with a command line interface (no pictures). They were widely used to access mainframe computers in the late 1970's and 1980's but use of them declined in the 1990's and they are seldom used anymore. However much of this howto also applies to command-line interfaces on Linux PC's which are in wide use today. It's not about the user programs one might run on the command line, but about setting up, managing, and understanding the interface itself Such as using a monitor as a virtual (text-only) console, using a text-window in a GUI such as xterm, connecting to a remote computer over a network via ssh, telnet, etc., or even using software on another PC to turn it into a serial-port text-terminal. All these 4 methods are known as "text-terminal emulation". But unfortunately, the main emphasis in this howto is real text terminals and the coverage of emulation is inadequate for the first 3 methods of emulation mentioned above. The Keyboard-and-Console-HOWTO filled much this gap but it was written for Linux 2.0 and now needs rewriting (or merging into this Text-Terminal howto). A new author is needed that has time to do all this. For the seldom used real text-terminals, it explains how they work, explains how to install and configure them, and provides some info on how to repair them. This HOWTO also provides a brief overview of modern GUI terminals.

Mastering Bash and Terminal | blockloop.io
If there is one tool that every developer uses regardless of language, platform, or framework it's the terminal. If we are not compiling code, executing git commands, or scp-ing ssl certificates to some remote server, we are finding a new version of cowsay to entertain ourselves while we wait on one of the former. As much as we use the terminal it is important that we are efficient with it. Here are some ways I make my time in the terminal efficient and effective.

PagerDuty Incident Response Documentation
This documentation covers parts of the PagerDuty Incident Response process. It is a cut-down version of our internal documentation, used at PagerDuty for any major incidents, and to prepare new employees for on-call responsibilities. It provides information not only on preparing for an incident, but also what to do during and after. It is intended to be used by on-call practitioners and those involved in an operational incident response process (or those wishing to enact a formal incident response process). See the about page for more information on what this documentation is and why it exists.

Modernization of Reactivity
Reactive programming has taken JavaScript by storm over the last decade, and for good reason; front-end development greatly benefits from the simplicity of writing user interface code that "reacts" to data changes, eliminating substantial error-prone imperative code tasked with updating UIs. However, while the popularity has increased, tools and techniques have not always kept up with modern browser functionality, web APIs, language capabilities, and optimal algorithms for performance, scalability, syntactic ease, and long-term stability. In this post, let's look at some of the newer technologies, techniques, and capabilities that are now available, and demonstrate these in the context of a new library, Alkali.

Serverless Architectures
Serverless architectures refer to applications that significantly depend on third-party services (knows as Backend as a Service or "BaaS") or on custom code that's run in ephemeral containers (Function as a Service or "FaaS"), the best known vendor host of which currently is AWS Lambda. By using these ideas, and by moving much behavior to the front end, such architectures remove the need for the traditional 'always on' server system sitting behind an application. Depending on the circumstances, such systems can significantly reduce operational cost and complexity at a cost of vendor dependencies and (at the moment) immaturity of supporting services.

An Original Approach to Web Game Development Using SVG
This paper presents an attempt of creating a browser game based on SVG. Some SVG games can already be found on the Internet [R1] [R2] but these are just simple games and are not massively multi-players. During the process, the question of how to leverage SVG at different steps of the development was raised. Many different technologies were needed, but SVG remains the guiding principle throughout the article.

Git is hard: screwing up is easy, and figuring out how to fix your mistakes is fucking impossible.

So here are some bad situations I've gotten myself into, and how I eventually got myself out of them in plain english*.

"Knit, Chisel, Hack: Building Programs in Guile Scheme" by Andy Wingo
This talk makes the case that Guile is a delightful medium for making crafty programs, from the most ephemeral scripts to long-lived systems that you can rely on for years. Guile takes the elegant Scheme programming language, integrates it with the POSIX environments that you know and loathe and love, and wraps it all up in a responsive, hackable environment that nurtures programs from the small up to the large. Guile hacker will give you a gentle introduction to the language as they lead you through the process of building cool stuff in Scheme. With all this going for it, maybe you will choose to make your next program in Guile!

"Point-Free or Die: Tacit Programming in Haskell and Beyond" by Amar Shah
Tacit programming, or programming in the “point-free” style, allows you to define a function without reference to one or more of its arguments. Thanks to automatic currying, point-free definitions can be easy to write in Haskell, OCaml, and F#.

But is point-free syntax just point-less? Ostensibly, tacit definitions can calibrate your code to the appropriate level of abstraction. But which level is most appropriate? When is a point-free definition better than its “pointed” variation? And when is it spectacularly worse?

Let's be explicit about tacit programming. Let's learn eta-reduction to produce it. Let's develop our intuition for its expressive power. Let's hunt for it in trusted libraries. Let's probe its origins in John Backus' function-level programming. Let's see it amplified in Joy and J, languages designed for maximum quiet. Let's speak at length, about the unspoken.

Async JavaScript with Reactive Extensions

In this talk, you'll learn how Netflix uses the Reactive Extensions (Rx) library to build responsive user experiences that strive to be event-driven, scalable and resilient. Learn the power of the Observable and how we've simplified our lives through the ability to filter, aggregate, compose and project data streams.

Join us while we discuss how Netflix uses Rx to:
- Declaratively build complex events out of simple events (ex. drag and drop)
- Coordinate and sequence multiple Ajax requests
- Reactively update the UI in response to data changes
- Eliminate memory leaks caused by neglecting to unsubscribe from events
- Gracefully propagate and handle asynchronous exceptions

52 Things People Should Know To Do Cryptography
Cryptography is a highly interdiscplinary area; calling on expertise in Pure Mathematics, Computer Science and Electronic Engineering. At Bristol we cover the full range of these topics and as such our students come with a variety of backgrounds and need to understand a diverse range of topics. Students starting can often feel overwhelmed by the types of knowledge that they feel they need to know; not knowing what they need to remember and what they should not bother remembering.
To aid you, below we have collected a set of 52 short points of things we think that at the end of the first year of a PhD all students should have some familiarity with. There is one point for every week of the year. If you know these things then following seminars, study groups and conference talks will be much easier. It will also help in putting your own work into context. Some of these are somewhat advanced topics, some of these are what one would pick up in certain undergraduate courses. This is deliberate since some are about being a cryptographer, and some are to address the fact that students start with different backgrounds.

Memento at the W3C
The Memento protocol is a straightforward extension of HTTP that adds a time dimension to the Web. It supports integrating live web resources, resources in versioning systems, and archived resources in web archives into an interoperable, distributed, machine-accessible versioning system for the entire web. The protocol is broadly supported by web archives. Recently, its use was recommended in the W3C Data on the Web Best Practices, when data versioning is concerned. But resource versioning systems have been slow to adopt. Hopefully, the investment made by the W3C will convince others to follow suit.

Language-theoretic Security
The Language-theoretic approach (LANGSEC) regards the Internet insecurity epidemic as a consequence of ad hoc programming of input handling at all layers of network stacks, and in other kinds of software stacks. LANGSEC posits that the only path to trustworthy software that takes untrusted inputs is treating all valid or expected inputs as a formal language, and the respective input-handling routines as a recognizer for that language. The recognition must be feasible, and the recognizer must match the language in required computation power.

Elm Plane - a Flappy Bird Clone in Elm
The really interesting topics are the ones you don't really get at first. For me, reactive programming is such a topic - I understand enough to get by, but I don't yet think in a functional reactive way. So, what better way to get into that state of mind than to try writing something in a language where there is no other choice but to write pure functional reactive code?
