Since the replacement is the same for all errors this makes it impossible to recover the original character. A better (but harder to implement) design is to preserve the original bytes, including the error, and only convert to the replacement when displaying the text. This will allow the text editor to save the original byte sequence, while still showing the error indicator to the user.

Then don’t use the phrase “replacement character”, because a) it’s not a character at all, and b) it’s specifically not the character with the Unicode name REPLACEMENT CHARACTER, and c) people easily get confused with issues like this.

it does not have a fixed glyph, though fonts that contain it tend to use very similar glyphs

How I can know which glyph the font does not support in that list?

To become an international superhero, fork this gist, make a shell-runable node.js application font-to-regexp.js that just takes your font file(s?) on the command line, invokes ttx for you on it(them), loads the result with jsdom, runs fontRange on it and prints the regexp to stdout, instead of doing the above steps manually. Oh, and brag about it in the comments here, of course, so other people find it too!

$ python checkfont.py /usr/share/fonts/**/DejaVuSans.ttf 65 12622 # a ㅎ

The script takes as arguments the font path and optionally code points / characters to search for:

Determine if a glyph exists in a given font

I'm looking to see if there is a way, in PHP, to determine if a glyph exists for a given character in a font.

Lucky for us, it’s super easy to use subdomains in development nowadays. http://lvh.me is a free service that resolves itself along with all subdomains to localhost.

Can you refactor your code so that instead of returning from within the transaction block you set a variable and then return outside of the block?

I think I had expected that existing rails developers would discover this problem in existing code through the deprecation warning to avoid a nasty surprise. I'm worried about my future kids learning Rails and writing perfectly looking Ruby code just to learn the hard way that return is sometimes a nono! Jokes aside, I think that no one expected that the deprecation will turn into silent rollbacks. This is a very controversial change, pretty much everyone taking part in the discussion on the deprecation PR raised some concerns about the potential consequences of this change. The only thing that was making it easier to swallow was the promise of making it clear to the user by throwing an exception after the rollback.

The problem is that the caller may write yield instead of block.call. The code I have given is possible caller's code. Extended method definition in my library can be simplified to my code above. Client provides block passed to define_method (body of a method), so he/she can write there anything. Especially yield. I can write in documentation that yield simply does not work, but I am trying to avoid that, and make my library 100% compatible with Ruby (alow to use any language syntax, not only a subset).

This breaks the TIMTOWTDI rule

I'm afraid you missed the joke ;-) While you believe spaces are required on both sides of an em dash, there is no consensus on this point. For example, most (but not all) American authorities say /no/ spaces should be used. That's the joke. In writing a line about "only one way to do it", I used a device (em dash) for which at least two ways to do it (with spaces, without spaces) are commonly used, neither of which is obvious -- and deliberately picked a third way just to rub it in. This will never change ;-)

The language was designed with this idea in mind, in that it “doesn't try to tell the programmer how to program.”

This motto has been very much discussed in the Perl community, and eventually extended to There’s more than one way to do it, but sometimes consistency is not a bad thing either (TIMTOWTDIBSCINABTE, pronounced Tim Toady Bicarbonate).[1] In contrast, part of the Zen of Python is, "There should be one— and preferably only one —obvious way to do it."

Bryan Caplan has made a spirited defense of school as signaling in his book, The Case Against Education. He argues that what is taught in school isn’t particularly useful on the job. Instead, schooling provides a mechanism for figuring out who has the talent, ambition and obedience to learn on the job successfully.

After the first week of the campaign, we realized what are the main problematic pillars and fixed them right away. Nevertheless, even with these improvements and strong support from the Gamefound team, we’re not even close to achieving the backer numbers with which we could safely promise to create a game of the quality we think it deserves.

First and foremost, we need to acknowledge that even though the funding goal has been met–it does not meet the realistic costs of the project. Bluntly speaking, we did not have the confidence to showcase the real goal of ~1.5 million euros (which would be around 10k backers) in a crowdfunding world where “Funded in XY minutes!” is a regular highlight.

For the tools of learning are the same, in any and everysubject; and the person who knows how to use them will, at any age, get themastery of a new subject in half the time and with a quarter of the effortexpended by the person who has not the tools at his command.

modern education concentrates onteaching subjects, leaving the method of thinking, arguing, and expressingone’s conclusions to be picked up by the scholar as he goes along;

Thewhole of the Trivium was in fact intended to teach the pupil the proper use ofthe tools of learning, before he began to apply them to “subjects” at all

Is it not the great defect of our education to-day (—a defect traceablethrough all the disquieting symptoms of trouble that I have mentioned—)that although we often succeed in teaching our pupils “subjects,” we faillamentably on the whole in teaching them how to think? They learneverything, except the art of learning.

Have you ever followed a discussion in the newspapers or elsewhere andnoticed how frequently writers fail to define the terms they use? Or howoften, if one man does define his terms, another will assume in his reply thathe was using the terms in precisely the opposite sense to that in which he hasalready defined them?

This is great because it works in Terminal, iTerm2, Chrome, Sublime & Outlook. The alternative (Karabina) is less good because that maps "Home" to Command+LeftArrow, which actually switches windows in Terminal.

opts = method(__method__).parameters.map(&:last).map { |p| [p, eval(p.to_s)] }.to_h SomeOtherObject.some_other_method(opts)

that's right, we don't want to do params = { ... } because then we're hardcoding the implementation and it becomes very coupled. The benefit of doing it like in my examples is that you can change the method signature and still automatically capture all keyword parameters.

Current ruby releases generate *.tar.gz, *.tar.bz2, *.tar.xz, and *.zip. But I think we can stop generating *.tar.bz2. I think *.tar.bz2 are less merit. For better size, *.tar.xz exist. For better compatibility, *.tar.gz and *.zip exist.

If we would have kept the call to super out of the #initialize_dup method, we would never have called initialize_copy, so it is important to keep that in.

The most important thing about research is to know when to stop.How does one recognize the moment? When I was eighteen orthereabouts, my mother told me that when out with a young man Ishould always leave a half-hour before I wanted to. Although I wasnot sure how this might be accomplished, I recognized the advice assound, and exactly the same rule applies to research. One must stopbefore one has finished; otherwise, one will never stop and neverfinish.

Also, the chances of breaking something are really high, because not even you remember how the code actually works.

Some people eventually realize that the code quality is important, but they lack of the time to do it. This is the typical situation when you work under pressure or time constrains. It is hard to explain to you boss that you need another week to prepare your code when it is “already working”. So you ship the code anyway because you can not afford to spent one week more.

To see if you are writing good code, you can question yourself. how long it will take to fully transfer this project to another person? If the answer is uff, I don’t know… a few months… your code is like a magic scroll. most people can run it, but no body understand how it works. Strangely, I’ve seen several places where the IT department consist in dark wizards that craft scrolls to magically do things. The less people that understand your scroll, the more powerfully it is. Just like if life were a video game.

Hi L0ki,as we depend on retailers with affiliate programs to run the site without ads, and Amazon being one of them, yes, we are following their rules so we can use API and their affiliate program.As Tomas said, we are also trying to get the history back, though we noticed we aren't the only site being affected by this.As for ignoring their API and doing it the hard way - that could be possible I guess but really not preferable.And we also understand anybody not wanting to buy from Amazon anymore (as some already told us), but to be fair, if the game is available anywhere else (and I have yet to randomly find a game which is available only at Amazon), you can always check the game info on ITAD to compare the price to other retailers.

If it's not, it should be illegal for them to forbid you from showing price history. This is restricting access to information, and it's probably supposed to benefit them from shady sales (increasing the base price just before a sale, so that the "X % off" is higher).

"We are not allowed to show you Amazon history"? What prompted this? Fill me in if I missed something :).EDIT: Camelcamelcamel can still show Amazon price history, so a bit befuddled here.

I would be interested to know what the legality of this is either way. I mean, do they really have any legal right to compel you not to list their price history? However, just knowing that Amazon doesn't want you to do this will make me less likely to purchase from them in the future. Anti-consumer behavior pisses me off. Edit: If this is related to API access couldn't you just manually scrape prices off the site instead and hammer their server? Or is this more related to not wanting to bite the hand that feeds you so to speak related to the funding you can get through referral links?

This has moved to part of the monorepo:

A 2015 study by OSoMe researchers Emilio Ferrara and Zeyao Yang analyzed empirical data about such “emotional contagion” on Twitter and found that people overexposed to negative content tend to then share negative posts, whereas those overexposed to positive content tend to share more positive posts.

In a set of groundbreaking studies in 1932, psychologist Frederic Bartlett told volunteers a Native American legend about a young man who hears war cries and, pursuing them, enters a dreamlike battle that eventually leads to his real death. Bartlett asked the volunteers, who were non-Native, to recall the rather confusing story at increasing intervals, from minutes to years later. He found that as time passed, the rememberers tended to distort the tale's culturally unfamiliar parts such that they were either lost to memory or transformed into more familiar things.

The fact that too much order can impede learning has becomemore and more known (Carey 2014).

unevaluatedProperties is like additionalProperties, except that it can "see through" $ref and "see inside" allOf, anyOf, oneOf, if, then, else

PRs will introduce various mechanisms step by step. Some of these have issues already. A possible breakdown could be: Annotation collection using instance values (links also does this) Defining annotations to which multiple keywords contribute (this is new, see Need more details of annotation collection #530) Defining subschema and keyword processing results to include annotations Processing sequence for keywords that dynamically rely on the results of static keywords The actual definition of unevaluatedProperties An example of unevaluatedProperties

Does this mean that the schema is available now since the bug is closed?

Nobody expects the v3 schema to be more of a perfect guarantee than the v2 schema (as said above, consider operationId). Just release a schema and let the dice fall where they may.

the errors that you get from JSON schema can sometimes be very confusing. I wanted to be able to generate errors that could easily be understood to speed up debugging time.

without a schema, you do not have a spec, you have an aspiration.

I'd also love to see a JSON schema along with the specification. I don't really trust myself to be able to accurately read the spec in its entirely, so for 2.0 I fell back heavily on using the included schemas to verify that what I'm generating is actually intelligible (and it worked, they caught many problems).

I'm not sure if there's a reason why additionalProperties only looks at the sibling-level when checking allowed properties but IMHO this should be changed.

It's unfortunate that additionalProperties only takes the immediate, sibling-level properties into account

additionalProperties applies to all properties that are not accounted-for by properties or patternProperties in the immediate schema.

additionalProperties here applies to all properties, because there is no sibling-level properties entry - the one inside allOf does not count.

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.

What I want is to use "additionalProperties: false" to validate a union of schemas, but it seems it isn't possible. I already tried with sevaral different combination, but I didn't make it works.

additionalProperties: false works on it, but not along with allOf, because only validate one schema or another.

Multiple different people have been discussing multiple different problems, and asking for examples of the other problems, talking past each other and generally this thread got to an unreadable point due to this confusion.

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.

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.
