This gem uses a Rack middleware to clear the store object after every request, but that doesn't translate well to background processing with Sidekiq. A companion library, request_store-sidekiq creates a Sidekiq middleware that will ensure the store is cleared after each job is processed, for security and consistency with how this is done in Rack.

Events AAA and BBB are mutually exclusive (cannot both occur at once) if they have no elements in common.

The complement of an event AAA in a sample space SSS, denoted AcAcA^c, is the collection of all outcomes in SSS that are not elements of the set AAA. It corresponds to negating any description in words of the event AAA.

If anything it thwarts separation of concerns to a degree.

Probably the only thing I'd like to see fixed now is the possibility of quick restart like in the old Timberman and not having to wait for the 'Game Over' screen to finally be back to the good ol' choppin'

What you want is not to detect if stdin is a pipe, but if stdin/stdout is a terminal.

stdin can be a pipe or redirected from a file. Better to check if it is interactive than to check if it is not.

The basic rule of thumb is: "I'm not aware of all types of security exploits. I must protect against those I do know of and then I must be proactive!".

But in all this incongruous abundance you'll certanly find the links to expect It's just what is wanted: the tool, which is traditionally used to communicate automatically with interactive programs. And as it always occurs, there is unfortunately a little fault in it: expect needs the programming language TCL to be present. Nevertheless if it doesn't discourage you to install and learn one more, though very powerful language, then you can stop your search, because expect and TCL with or without TK have everything and even more for you to write scripts.

In many computing contexts, "TTY" has become the name for any text terminal, such as an external console device, a user dialing into the system on a modem on a serial port device, a printing or graphical computer terminal on a computer's serial port or the RS-232 port on a USB-to-RS-232 converter attached to a computer's USB port, or even a terminal emulator application in the window system using a pseudoterminal device.

unbuffer works with piping to less. That may be an easier syntax than what you've got.

Factory FunNER is the sequel and a very solid improvement to Factory Fun. It uses hexes instead of squares to allow more creative building, and some subtle improvements to scoring, length, and machine placement rules really improve things.

We also know people need a good sized group and time to see the impact and value of a platform like Stack Overflow for Teams. Our previous 30 day free trial of our Basic tier wasn’t long enough. Now, Stack Overflow for Teams has a free tier for up to 50 users, forever.

With Stack Overflow for Teams being a flexible platform, we’ve seen customers use it for a wide variety of use cases: A platform to help onboard new employees A self-serve help center to reduce support tickets Collaboration and documentation to drive innersource initiatives Breaking down silos and driving org wide transformation like cloud migration efforts A direct customer support platform Enable people who are working towards a common goal, whether a startup or a side project, to develop a collective knowledge base

Gilles has written an excelent answer here (see unix.stackexchange.com/a/105655/49721) explaining why "A space-separated list of file names doesn't really work: what if one of the file names contained spaces?"

If it's a list of actual pathnames, just replacing spaces by newlines may obviously mangle pathnames that contain embedded spaces, such as /User/myself/VirtualBox VMs/.

2 out of 3 people in my household do not find it easy to understand. Maybe that is is not representative, but keep in mind that something you yourself understand (or in this case think you understand) always seems easy.

For path names with newlines it is better to quote each pathname.

But we can use a two characters delimiter: / (space slash) That pair of characters could only exist at the beginning of a new (absolute) path:

substitute /one space or more/ for /newline/ globally

A crucial difference between representations of relative error inthese equations compared withEquations 6and7 for the single-facet designs is that three sources of measurement error varianceare separately represented, withpt2ntequaling specific-factor error,po2noequaling transient error, andpto,e2ntnoequaling random-responseerror. Effects fortasks, occasions, and their interaction are includedin the denominator for the D-coefficient but not the G-coefficientbecause those effects can change the absolutemagnitude of scoresbut not their relative differences.

“It is less clear that way” — that is just arbitrary, even uninformed. There is nothing clearer about def self.method. As demonstrated earlier, once you grasp the true meaning of it, def self.method is actually more vague as it mixes scopes

What's the point of playing a game featuring fjords without also including vikings to pillage the other player's lands...I've actually developed two additional tiles for Fjords: The Dragon and The Marauding Hoard. Both do exactly that.(I've play tested them with a friend well over 40 times and we both agree that with an expanded set of Fjords tiles, these two greatly improve the game for us. I'll write the tiles up and post them to BGG... eventually)

I opened a new thread to discuss that aspect.

It's as good as online-only, however with noone actually playing you'll find yourself queueing for bot matches (even having to wait for the "other players" to select their vehicles). You want to just race your mate in a local game- nope! Local races are single-player only (apparently the devs couldn't be bothered with coding a split-screen or zooming camera to enable local multiplayer races). Want to play online but specify the map? Nope! Play a game online with a good lobby and want to stick with that group? Nope! Every game forces you to exit after each event.

Firstly, I don't like being thrown back into the menu every single time I fail a challenge, I prefer to be thrown right back in to it, maybe a "retry" option should be there to throw you right back in once you fail a challenge.

In Deutschland ist bisher noch keine Anwendung bekannt Die HOOU Hamburg Open Online University fördert derzeit ein DoOO Projekt. Projektmitarbeiter sind Christian Friedrich und Katharina Schulz.

“Digital technology allows us to be far more adventurous in the ways we read and view and live in our texts,” she said. “Why aren’t we doing more to explore that?”

DM gives you simple but/and powerful tools to mark up, annotate and link your own networked collections of digital images and texts. Mark up your image and text documents with highlights that you can then annotate and link together. Identify discreet moments on images and texts with highlight tools including dots, lines, rectangles, circles, polygons, text tags, and multiple color options. Develop your projects and publications with an unlimited number of annotations on individual highlights and entire image and text documents. Highlights and entire documents can host an unlimited number of annotations, and annotations themselves can include additional layers of annotations. Once you've marked up your text and image documents with highlights and annotations, you can create links between individual highlights and entire documents, and your links are bi-directional, so you and other viewers can travel back and forth between highlights. Three kinds of tools, entire digital worlds of possible networks and connections.

"Weltweit steigt mit dem Klimawandel das Risiko von extremen Regenfällen und Überschwemmungen", fasst Will Steffen von der australischen Nationaluniversität zusammen. Der Professor ist einer der führenden Klimatologen Australiens. "Die globale Durchschnittstemperatur ist bereits um etwa 1,1 Grad Celsius gestiegen. Für jeden Temperaturanstieg von einem Grad kann die Atmosphäre etwa sieben Prozent mehr Wasser aufnehmen", so Steffen

each of which we could show to be more beautiful, and more usable than the original.

Find-ability / scan-ability: The time it took a participant to find and click on a requested element

You might not always notice, but Material Design is constantly evolving and iterating based on research.

Many designers strive to create products that are so easy to navigate, their users can flow through them at first glance. To design something with this level of intuitiveness, it’s imperative designers understand affordances—what they are and how to use them.

I managed to do half the work. But that’s exactly it: It’s work. It’s designed that way. It requires a thankless amount of mental and emotional energy, just like some relationships.

I realized it was foolish of me to think the internet would ever pause just because I had. The internet is clever, but it’s not always smart. It’s personalized, but not personal. It lures you in with a timeline, then fucks with your concept of time. It doesn’t know or care whether you actually had a miscarriage, got married, moved out, or bought the sneakers. It takes those sneakers and runs with whatever signals you’ve given it, and good luck catching up.

Pinterest doesn’t know when the wedding never happens, or when the baby isn’t born. It doesn’t know you no longer need the nursery. Pinterest doesn’t even know if the vacation you created a collage for has ended. It’s not interested in your temporal experience.This problem was one of the top five complaints of Pinterest users.

Now that we’ve gotten newer layout features — again, like grid and flexbox — floats, too, have sort of fallen by the wayside, perhaps either because there are better ways to accomplish what they do

There has been some Quality-of-Life changes as well, which I really appreciate. For example, the long elevator in level 10 has been replaced with a teleporter. There's been some balance changes as well, but aside from level 10, I haven't checked them out.

1a : touching lightly : incidental, peripheral tangential involvement also : of little relevance arguments tangential to the main point

the game is designed in such a way that you don't need too many tries to figure out boss patterns or tricky platforming sections. Another nice feature is that you can warp between different areas so you don't have to do a bunch of backtracking.

It feels like it was thrown together in a weekend using parts from "Think To Die" since even the successful act of feeding your chickens has the same blood-splatter-on-camera-lens that you would get from scoring in Think To Die where your goal is to kill all of your people as opposed to this where you are feeding animals, so what's with the blood splatter? It just shows a lack of attention to detail.

It is also the first game I've seen whose icon for "mute" is not a crossed-out speaker/note, but a symbol for "pause" in musical notation...

Yeah, I probably think of using foam before anyone else does.

however, if this is relevant to just one spec, you don't necessarily need to include devise helpers to all your controllers specs, you can just explicitly include those helpers in that one controller describe block: require 'spec_helper' describe MyCoolController include Devise::TestHelpers it { } end

There is no request.env in functional tests because the functional tests are supposed to remain at the controller level.

We encourage course creators to dedicate time in their courses for a retro. Every cohort of a course is an experiment shaped by all participants, and what you learn can improve the course in important ways. Getting good feedback from learners is a key part of making sure that the course is always evolving in the right direction.

The problem is that these are not static assets. The raw file view, like any other view in a Rails app, must be rendered before being returned to the user. This quickly adds up to a big toll on performance. In the past we’ve been forced to block popular content served this way because it put excessive strain on our servers.

A one-liner alternative for hash-only cases can be implemented using Enumerable#reduce: root = {} [:a, :b, :c].reduce(root){@1[@2]||={}}[:d] = 'E' # root => {:a=>{:b=>{:c=>{:d=>"E"}}}}

I think the issues/problems specified in the comments are not present with a Hash-only implementation. :) I would be supportive of re-considering this feature just for use with a Hash, where I believe 80% of the real-life use cases would (and do) exist. I have encountered this need before in the wild, but not with Arrays.

In the Camerer, Loewenstein and Weber's article, it is mentioned that the setting closest in structure to the market experiments done would be underwriting, a task in which well-informed experts price goods that are sold to a less-informed public. Investment bankers value securities, experts taste cheese, store buyers observe jewelry being modeled, and theater owners see movies before they are released. They then sell those goods to a less-informed public. If they suffer from the curse of knowledge, high-quality goods will be overpriced and low-quality goods underpriced relative to optimal, profit-maximizing prices; prices will reflect characteristics (e.g., quality) that are unobservable to uninformed buyers ("you get what you pay for").[5] The curse of knowledge has a paradoxical effect in these settings. By making better-informed agents think that their knowledge is shared by others, the curse helps alleviate the inefficiencies that result from information asymmetries (a better informed party having an advantage in a bargaining situation), bringing outcomes closer to complete information. In such settings, the curse on individuals may actually improve social welfare.

Such research drew from Baruch Fischhoff's work in 1975 surrounding hindsight bias, a cognitive bias that knowing the outcome of a certain event makes it seem more predictable than may actually be true.[5] Research conducted by Fischhoff revealed that participants did not know that their outcome knowledge affected their responses, and, if they did know, they could still not ignore or defeat the effects of the bias.

This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students.

My preference here is biased by the fact that I spend everyday at work building web components, so Svelte's approach feels very familiar to slots in web components.

Svelte is there when I need it with useful APIs, but fades into the background as I put my app together.

but I like that Svelte comes with a good CSS story out the box.

Svelte is different in that by default most of your code is only going to run once; a console.log('foo') line in a component will only run when that component is first rendered.

Tree (data structure)

Originally he had used the terms usage scenarios and usage case – the latter a direct translation of his Swedish term användningsfall – but found that neither of these terms sounded natural in English, and eventually he settled on use case.

The is-a relationship may also be contrasted with the instance-of relationship between objects (instances) and types (classes): see Type–token distinction.

Two of the predominant types of relationships in knowledge-representation systems are predication and the universally quantified conditional.

The precise semantic interpretation of an atomic formula and an atomic sentence will vary from theory to theory.

There may only be historical reasons that, for example, the periodic table is called a classification rather than a taxonomy

Sometimes lexicography is considered to be a part or a branch of lexicology, but properly speaking, only lexicologists who write dictionaries are lexicographers.

Semantics: deals with the formal properties and interrelation of signs and symbols, without regard to meaning.

I’ve been promising for many years and it turned out I couldn’t have fully designed it without the tools we do have now.

With all this “monetization” happening around Trailblazer, we will also make sure that all free and paid parts of the project grow adult and maintan an LTS - or long-term support - status. Those are good news to all you users out there having been scared to use gems of this project, not knowing whether or not they’re being maintained, breaking code in the future or making your developers addicted to and then cutting off the supply chain. Trailblazer 2.1 onwards is LTS, and the last 1 ½ years of collaboration have proven that.

For pluggability, an endpoint is split into a Protocol and an Adapter part. This separates generic logic from environment-dependent code.

Note how a handful of default steps lead into six standardized termini, allowing to plug protocols into different adapters. Imagine replacing your self-written API adapter with a canonical JSON-API adapter, for example.

Most “legacy” operations don’t have this output, yet. However, the Model() macro now supports this terminus.

Can we occupy technology with love?

It's a pet peeve, but I wish that people would stop describing their HTTP RPC APIs using the term "REST".

The challenge, honestly, is the tyranny of choice. It takes research and time. As Linux users will tell you, the hardest part of using Linux is deciding the exact distro to use, because there’s so much choice. It can be overwhelming.

This is not a fork. This is a repository of scripts to automatically build Microsoft's vscode repository into freely-licensed binaries with a community-driven default configuration.

It has long since been demonstrated that Parkinson's patients have a different microbiome in the intestines than healthy people

I was pretty annoyed with myself for having fallen for the trap of not documenting my own systems, but not sure how I could have remembered all of the Hugo-isms

In those wretched countries where a man cannot call his tongue his own, he can scarce call anything his own. Whoever would overthrow the liberty of a nation must begin by subduing the freeness of speech ... Without freedom of thought there can be no such thing as wisdom, and no such thing as public liberty without freedom of speech, which is the right of every man ...

the community is both endlessly creative and genuinely interested in solving big issues in meaningful ways. Whether it's their commitment to careful (and caring) community stewardship or their particular strain of techno-ethics, I have been consistently (and pleasantly) surprised at what I've seen during the last twelve months. I don't always see eye-to-eye with their decisions and I don't think that the community is perfect, but it's consistently (and deliberately) striving to be better, and that's a fairly rare thing, online or off.

The Obsidian vault that I've created for the students is secure (by invitation only in Dropbox) and THEY CAN CONTRIBUTE to it. I've put the questions for discussion in the content sections, and have asked students to answer the questions on the page. This hasn't resulted in the types of threaded discussions I was hoping for, but improvements to the interface and better questions will hopefully lead to that.

I hadn't really thought that much about the pedagogical aspects (they don't really teach PhD historians pedagogy where I went to school, or I missed it somehow, so I've been trying to educate myself since then).
