You have stumbled upon the most common problem in JSON Schema, that is, its fundamental inability to do inheritance as users expect; but at the same time it is one of its core features.

this is one of the best examples I've read that explains the full picture. Thanks @ted epstein

This is confusing spec language. In particular the last sentence is too hard to follow - the definitions can't be the same and not be the same.

JSON Schema allows for additionalProperties both a boolean or an object value. true is interpreted as "additional properties follow no restrictions", false means "no additional restrictions", and an object is interpreted as a JSON schema applied to the property values (the empty object is thus equivalent to true).

Good code is its own best documentation. As you’re about to add a comment, ask yourself, "How can I improve the code so that this comment isn’t needed?". Improve the code and then document it to make it even clearer.

Also be aware of how Ruby handles aliases and inheritance: an alias references the method that was resolved at the time the alias was defined; it is not dispatched dynamically.

Prefer alias when aliasing methods in lexical class scope as the resolution of self in this context is also lexical, and it communicates clearly to the user that the indirection of your alias will not be altered at runtime or by any subclass unless made explicit.

Booleans and nil can be compared by identity and therefore the `be` matcher is preferable as it is a more strict test.

git -c log.follow= log: that will unset log.follow, just for that one git log instance.

If we ever moved a file to a different location or renamed it, all its previous history is lost in git log, unless we specifically use git log --follow. I think usually, the expected behavior is that we'd like to see the past history too, not "cut off" after the rename or move, so is there a reason why git log doesn't default to using the --follow flag?

Note: Git 2.6+ (Q3 2015) will propose that in command line: see "Why does git log not default to git log --follow?" Note: Git 2.6.0 has been released and includes this feature. Following path changes in the log command can be enabled by setting the log.follow config option to true as in: git config log.follow true

If you want to replace many blobs, trees or commits that are part of a string of commits, you may just want to create a replacement string of commits and then only replace the commit at the tip of the target string of commits with the commit at the tip of the replacement string of commits.

As of Git 1.6.5, the more flexible git replace has been added, which allows you to replace any object with any other object, and tracks the associations via refs which can be pushed and pulled between repos.

Graft points or grafts enable two otherwise different lines of development to be joined together. It works by letting users record fake ancestry information for commits. This way you can make git pretend the set of parents a commit has is different from what was recorded when the commit was created.

The next step is to graft the two branches together, skipping the two commits which renamed the folder. (Otherwise there will be a weird jump where everything is deleted and recreated.)

This repair fitting is designed to seal leaks at a glue joint for Sch.40 pipe.

Calling the same filter multiple times with different options will not work, since the last filter definition will overwrite the previous ones.

IMO passive vs. active voice has no impact on the ambiguousness of the sentence.

This hasn't yet been scheduled, but we're tracking it on our backlog as something we want to do this year. A few months ago, we arranged for additional capacity to address items like this that have waited for so long. Now that additional capacity is available, it's just a matter of scheduling based on relative priority. We're anxious to get this one done, and I hope to soon have a clearer date to post here.

Giving ~, YAML’s representation of nil, as a value cancels the setting of the corresponding key in the parent configuration.

the AST version of the code is vastly superior IMHO. The knowledge about what constitutes an access modifier is already encoded in the system so it makes more sense to just call the method to test the type of node. The regexp solution may be expedient, but it's not as resilient to change -- if new access modifiers are added in the future it's very likely this code won't be updated, which will be the source of a bug.

When you google the problem and realized your answer is how you fix it: #557 (comment)

asdf is not intended to be a system package manager. It is a tool version manager.

Just because you can create a plugin for any tool and manage its versions with asdf, does not mean that is the best course of action for that specific tool.

Shims are just tiny wrappers created by asdf that just forward execution to the real versioned executables installed by asdf. This way, asdf has a single shims directory added to your PATH and has no need of mangling the PATH for every installed version.

To criticise Rust for being a complex language misses the point: it's designed to be expressive, which means having a lot of features, and in many situations that's what you want from a programming language.

For example, whereas C programmers have argued for years about where to put their brackets, and whether code should be indented with tabs or spaces, both Rust and Go eliminate such issues completely by using a standard formatting tool (gofmt for Go, rustfmt for Rust) which rewrites your code automatically using the canonical style. It’s not that this particular style is so wonderful in itself: it’s the standardisation which Rust and Go programmers appreciate.

If you like the functional style of programming, though, you’ll find a lot more facilities for it in Rust, because Rust has a lot more facilities than Go in general.

Rust is integrated with Firefox. This integration is cleverly dubbed ‘oxidation’ and has a whole wiki page dedicated to the project. 

The single-line commit trailers ^Update-Info: *(.*) on version tagged commits are used to assemble a small changelog during update, which is presented to the user. The single line can contain important information/links to relevant fixes and changes.

Ruby's keyword args work a little differently than similar implementations (selectors in Objective C, for instance). The value on the right-hand side of the colon is the default, not the local name.

an equivalent of R's signif function in Ruby.

This rounds to the specific number of decimal places, but what's wanted is to round to a specific number of significant digits.

R is the implementation of the S programming language combined with lexical scoping semantics inspired by Scheme.

The S language is often the driver programming language for research in statistical methodology, and R gives an Open Source route to participation in that activity.

The modern implementation of S is R

So when should you use rbspy, and when should you use stackprof? The two tools are actually used in pretty different ways! rbspy is a command line tool (rbspy record --pid YOUR_PID), and StackProf is a library that you can include in your Ruby program and use to profile a given section of code.

One common use case for rbspy is profiling slow unit test runs -- instead of spending a bunch of time adding instrumentation, you can run rbspy record ruby my-test.rb and instantly get profiling information about what's going on.

a benchmark tells you how slow your code is ("it took 20 seconds to do X Y Z") and a profiler tells you why it's slow ("35% of that time was spent doing compression").

Because rbspy is a sampling profiler (not a tracing profiler), it actually can't tell you how times a function was called -- it just reports "hey, I observed your program 100,000 times, and 98,000 of those times it was in the calculate_thing function". ruby-prof is a tracing profiler for Ruby, which can tell you exactly how many times each function was called at the cost of being higher overhead.

it's useful to understand the difference between "self time" and "total time" spent in a function

Nothing in the profiling guide is Ruby- or rbspy-specific — it all applies to profiling in general.

However, as an interpreted language, Ruby is slow compared to compiled languages. The general solution adopted by Rubyists was to throw more hardware at the problem. “Hardware is cheaper than salaried engineers,” went the common maxim.

That is called profiling, not performance testing. Performance testing should ensure that a piece of code runs within a desired amount of time, given a certain context, before the new code goes into production.

Pipes Puzzles is a is a Unity Asset flip, what Valve calls a "fake game". The "developer", beans rolls (aka Simple Logic Games, beats rolls, Crewxaa etc), took a Unity pack for making a Pipe Mania ripoff, changed the name, and dumped the result onto Steam. They're attempting to scam people into buying this, so they can get your money for someone else's work. You can see the same game published by McGeeMind on Amazon's app store.beans rolls have shown a repeat pattern of unethically dumping other people's work onto Steam as a cheap, nasty cash grab. Here's some examples so you can see for yourself: "Starveling WayE" = 2D Roguelike Tutorial developed by Unity Technologies "Sniper GameE" = Advanced Sniper Starter Kit developed by Hardworker Studio "Air StrikeE" = Air Strike Starter Kit developed by Hardworker Studio "Bouncy CubeE" = Bouncy Cube 2d developed by Game HUB "BranchesE" = Branches developed by SgLib Games "Hit ConfirmedE" = Bullet developed by Lucas Lopes "InsipidE" = Color Picket Game developed by Daniel Buckley "Down The HillE" = Emoji Down The Hill developed by SgLib Games "Connect the DotsE" = Flow Free developed by bupisource.com "Connect the Dots 3DE" = J Connect Kit developed by Jun "Math GameE" = Math Game - Brain Workout developed by App Advisory "Moon DefenseE" = Moon Defense Game Kit - FREE developed by Azureda Games "Neon ArenaE" = Neon Space Fighter developed by Aleksa Racovic "vision\memory\mazeE" = Procedural Mazes developed by Denis Mustakimov "Winding RoadE" = Shape Change Complete Game developed by Ragendom "Spinner BreakerE" = Spin Breakout developed by SgLib Games "Pick The LockE" = Stop The Lock developed by App Advisory "Twin BallsE" = Twin Balls developed by SgLib Games "Wall to WallE" = Wall to Wall developed by soloo studio "Wavy TripE" = Wavy Trip developed by SgLib "Badlands RacerE" = X-Racer developed by Deer CatThe products that result from asset flips aren't "real" games. They lack depth and content, because they're just simplistic copies of demos or tutorials. In this case, "Color Picket Game" is just a basic demo/tutorial for making a minimalist color matching game, and doesn't have any merit as a proper, fully fledged PC game, so a copy+paste of it can't be recommended.

But others, including Garner, believe, I think rightly, that while it can be ok to omit the hyphen in compound-noun adjectives, the better practice is to include the hyphen to ensure no confusion (especially since including the hyphen never triggers a miscue).

  high school kids vs. high-school kids (school kids on pot, or kids in high school)   one armed bandit vs. one-armed bandit (an armed bandit alone, or a bandit with one arm)   criminal law professors vs. criminal-law professors   small animal veterinarian vs. small-animal veterinarian   old boat dealer vs. old-boat dealer   bad weather report vs. bad-weather report   big business owner vs. big-business owner

Without the hyphen the reader is left wasting time wondering “what’s the real meaning here?” Without the hyphens readers struggle to get your meaning right, which slows them down. The hyphen eliminates the ambiguity, and tripping over it.

Use kids-in-mind.com instead.

If a site tries to charge me for work others do for free I block them. They're not paying these people to review, there's no standard of quality for these reviews. It's not something that should be charged for. Or maybe I just overdo things, I even refuse to use the self-checkouts at stores because there's someone they can pay for that and unless I get a discount for my work I'm not doing it. People keep allowing companies to get away with crap like that and now stores will have 1 employee and 20 self-checkout stations

I used common sense media for years as my kids are 9/10 now... Use kids-in-mind.com instead. My guess is that common sense media is fine with 1/10th (or less) of the traffic they used to have, if the 1/10th is paying...Not gonna pay for something I use maybe once a month to check one category, it is disappointing though.

Self checkouts should be giving us a discount for checking our own selves out. I've learned that you may put items under your cart and accidentally pay yourself by missing an item or two if you're in a pressured rush. Often I forget items in the store because I forget to bag them in a hurry. I figure the score is about even. I'm too lazy to go back and get what I forget by the time I get home. At least we should get a dollar off per $50 spent. It takes me 5 times as long to check myself out.

if an invitee is invited to do business in a store and is injured snooping around in the private storage area, he does not have invitee status in that area.

If there is no database initialized when the container starts, then a default database will be created. While this is the expected behavior, this means that it will not accept incoming connections until such initialization completes. This may cause issues when using automation tools, such as docker-compose, which start several containers simultaneously. If the application you're trying to connect to MySQL does not handle MySQL downtime or waiting for MySQL to start gracefully, then putting a connect-retry loop before the service starts might be necessary.

the problem with docker builds is the made-up concept of "context". Dockerfiles are not sufficient to define a build, unless they are placed under a strategic directory (aka context), i.e. "/" as an extreme, so you can access any path (note that that's not the right thing to do in a sane project either..., plus it makes docker builds very slow because docker scans the entire context at start).

I would not change the project structure to accommodate Docker (or any build tools).

Each environment can be matched with the following environment spec:

This is telling the browser that the width of #header should be 100% with a padding of 30px. Since padding is not counted into the width, the actual width ends up to be 100% + 60px. So, in order to make sure this fits into the page, you need to subtract 60px (30px to the left + 30px to the right) from the 100% width and it will fit into the browser. Luckily you are easily able to do this with CSS: #header{ padding: 30px; width: calc(100% - 60px);

Thats because you have both width and padding set to one element. And by default padding is added on top of width. (Making it 100% + 2*30px of width). #header{ padding: 30px; width: 100%; } Either remove padding and add it to an inner element with no width set, or use: box-sizing: border-box; Which makes the width calculation include padding. :)

some kudos for not doing review manipulation to get fake positive reviews, and also kudos for not doing an asset flip. No matter how bad this is, it's their original work, and that's (more or less) a good thing in this age of Russian asset flip garbage.

TREE(3) is surprisingly large.TREE(1) = 1 and TREE(2) = 3, but then TREE(3) is suddenly vastly beyond comprehension.But once you know that TREE(3) is too big to grok, there’s not a lot left to be said about TREE(n) for specific n > 3; surely they’re bigger. In fact, they are probably so much bigger that even TREE(4) will dwarf TREE(3) to a much greater extent than TREE(3) dwarfs our familiar numbers. But that isn’t surprising once you know about TREE(3).In principle, of course, there is no reason you have to stop. You could consider, for example, TREETREE(TREE(3)) (3), where you start by plugging 3 into TREE, then plug that into TREE, and keep going through a total of TREE(TREE(3)) iterations. That would definitely be a (disturbingly, in my opinion) large number. But it’s not particularly interesting, as large numbers go.

The interaction operator strict requires a strict sequencing (order) of the operands on the first level within the combined fragment

The interaction operator seq means that the combined fragment represents a weak sequencing between the behaviors of the operands.

Weak sequencing reduces to a parallel merge when the operands are on different sets of participants. Weak sequencing reduces to strict sequencing when the operands work on the same participant.

The definitions provided are tremendously valuable to figure out the very similar but different two paradigms.

I recommend using the term “parallel” when the simultaneous execution is assured or expected, and to use the term “concurrent” when it is uncertain or irrelevant if simultaneous execution will be employed.

multiple sub-tasks of a task

Concurrency is about dealing with lots of things at once. Parallelism is about doing lots of things at once.

A system is said to be concurrent if it can support two or more actions in progress at the same time. A system is said to be parallel if it can support two or more actions executing simultaneously.

Parallelism means that an application splits its tasks up into smaller subtasks which can be processed in parallel, for instance on multiple CPUs at the exact same time.

Concurrency means executing multiple tasks at the same time but not necessarily simultaneously.

Concurrency means that an application is making progress on more than one task at the same time (concurrently)

Mermaid allows even non-programmers to easily create detailed and diagrams through the Mermaid Live Editor.

Diagramming and documentation costs precious developer time and gets outdated quickly. But not having diagrams or docs ruins productivity and hurts organizational learning. Mermaid addresses this problem by enabling users to create easily modifiable diagrams, it can also be made part of production scripts (and other pieces of code).

We definitely want to have a way to monitor this "queue" as a follow-up with a Prometheus counter. This counter could be used to create alerts in case the queue grows significantly, for example: the scheduled (every 1 minute) worker cannot keep up with the deletions.

A review from the Technical Writing team before you merge is recommended. Reviews can happen after you merge.

Each commit should meet the following criteria: Have a well-written commit message. Has all tests passing when used on its own (e.g. when using git checkout SHA). Can be reverted on its own without also requiring the revert of commit that came before it. Is small enough that it can be reviewed in isolation in under 30 minutes or so.

I wrote my own OAuth 2 implementation in the end, it actually wasn't that hard once you understand the spec.

We want to use the Doorkeeper gem to implement an OAuth provider in our app. However, we use 2 factor auth in the login process, so we need a way to modify the password grant to accept email, password and a 2fa token (and respond with an appropriate error if the 2fa token is required and missing).

2) The kanji are organized in chapters with wide themes (respectively: world, food, animals, people, body, spirit, power, learn, tools, places, journey). These chapters are in turn divided up into mini-themes dealing with each chapter (for example, different animals and ideas associated with them). This helped me a lot in mentally organizing kanji and their meanings.

Water your lawn deeply about once a week, or when the grass looks slightly wilted, providing about an inch (2.5 cm.) of water each time. Avoid frequent, shallow irrigation which results in weak roots that can’t tolerate summer heat. Don’t water if the lawn doesn’t need it.

Roots growing along the surface of the soil is equivalent to an exposed nerve: they are not protected from the environment.

Water deeply but only when the grass shows signs of stress; deep, infrequent irrigation creates strong, drought-tolerant roots. Never water every day; watering too frequently encourages shallow, weak roots and unhealthy grass. For a healthy lawn and sturdy roots, wait as long as possible before waterin

I just learned today that extend apparently doesn't override class methods that are already defined, even though the extend happens later:

I don’t like that when I read the Basecamp news and had a visceral reaction, my first thought was, “Will my commit access be revoked if I share what’s on my mind?” It’s incredibly unclear what mechanisms exist to remove commit access from someone against their will, and also unclear what recourse those people can take to get it re-instated.

It can be exhausting to backchannel and “find buy-in” for every little thing.

The funny thing is that I didn’t even realize that’s what I was doing. I loved a system driven by programmers because it “made sense to me” about getting changes in.

I loved that if I “did the work”, then I got the benefits.

The older you are, the harder it is to get hired; despite laws and expectations to the contrary, unconscious, and even conscious, age discrimination does exist. When you have more experience, you will often be interviewed by people who in the normal course of circumstances would be reporting to you.

Indeed, judging from the accounts of the many employees who have now gone on record about this issue, the “debates” that have been happening at Basecamp are precisely the kinds of conversations that happen when you have a diverse workforce. Different issues affect different people differently, and being able to speak freely about those differences is the hallmark of a healthy culture. But by framing these discussions as “acrimonious debates” rather than “challenging conversations,” Hansson has positioned himself not as a peacemaker, but as a tyrant hell-bent on taking his toys and going home; shutting down discussions rather than holding space for growth and discovery.

If Hansson and Fried had been able to tolerate the dissenting opinions of their own employees, they might have been in for a difficult few weeks or months, but the long-term benefit of cultivating an atmosphere of trust would have been invaluable. Instead, they decided to make their tantrum international news. In doing so, they have all but dismantled the positive reputation they spent more than a decade carefully crafting.

Epics, issues, requirements, and others all have similar but just subtle enough differences in common interactions that the user needs to hold a complicated mental model of how they each behave.

Issues are not extensible enough to support all of the emerging jobs they need to facilitate.

Issues are starting to become cluttered as we add more capabilities to them, and they are not perfect

Using labels to show issue types is cumbersome and makes reporting views more complex.

This leads to duplicated effort and ultimately small differences between common interactions.

New functionality is typically implemented with first class objects that import behavior from issues via shared concerns.

There is not a coherent interaction model across different types of issues because we use labels for this.

Here are some problems with current issues usage and why we are looking into work items:
