I have been doing different things w/ Ruby for a couple of years now and the only bad thing I can say about it is that it makes programming in other languages feel awfully burdensome. = )

I would like to understand this design then. In my experience it has only served to limit what I can achieve, and gained me no additional benefit.

Benoit Daloze of TruffleRuby points out that this is all much easier to read if you define your Ruby internals in Ruby, like they do. He's not wrong.

Identification of type IV conjugative systems that are systematically excluded from metagenomic bins

Until now, we had a lot of code. Although we were using a plugin to help with boilerplate code, ready endpoints, and webpages for sign in/sign up management, a lot of adaptations were necessary. This is when Doorkeeper comes to the rescue. It is not only an OAuth 2 provider for Rails but also a full OAuth 2 suite for Ruby and related frameworks (Sinatra, Devise, MongoDB, support for JWT, and more).

When you select the finest place to study architecture abroad, you will be able to choose from a variety of programs at all levels–bachelor’s, master’s, and doctoral.

Currently Xournal++ does not have shortcuts/keybindings configurable in the preferences. However you can write your custom plugin to achieve exactly that.

So far for the obligatory warning. I get the point, I even agree with the argument, but I still want to send a POST request. Maybe you are testing an API without a user interface or you are writing router tests? Is it really impossible to simulate a POST request with Capybara? Nah, of course not!

You can also go to the Ruby OAuth Client Library to download the source code and run: 1gem build intuit-oauth.gemspec to build your own gem if you want to modify certain functions in the library.

Computers can only deal with well-structured problems

The paradox of information systems[edit] Drummond suggests in her paper in 2008 that computer-based information systems can undermine or even destroy the organisation that they were meant to support, and it is precisely what makes them useful that makes them destructive – a phenomenon encapsulated by the Icarus Paradox.[9] For examples, a defence communication system is designed to improve efficiency by eliminating the need for meetings between military commanders who can now simply use the system to brief one another or answer to a higher authority. However, this new system becomes destructive precisely because the commanders no longer need to meet face-to-face, which consequently weakened mutual trust, thus undermining the organisation.[10] Ultimately, computer-based systems are reliable and efficient only to a point. For more complex tasks, it is recommended for organisations to focus on developing their workforce. A reason for the paradox is that rationality assumes that more is better, but intensification may be counter-productive.[11]

What Is a Blockchain Oracle? A blockchain oracle is a secure piece of middleware that facilitates communication between blockchains and any off-chain system, including data providers, web APIs, enterprise backends, cloud providers, IoT devices, e-signatures, payment systems, other blockchains, and more. Oracles take on several key functions: Listen – monitor the blockchain network to check for any incoming user or smart contract requests for off-chain data. Extract – fetch data from one or multiple external systems such as off-chain APIs hosted on third-party web servers. Format – format data retrieved from external APIs into a blockchain readable format (input) and/or making blockchain data compatible with an external API (output). Validate – generate a cryptographic proof attesting to the performance of an oracle service using any combination of data signing, blockchain transaction signing, TLS signatures, Trusted Execution Environment (TEE) attestations, or zero-knowledge proofs. Compute – perform some type of secure off-chain computation for the smart contract, such as calculating a median from multiple oracle submissions or generating a verifiable random number for a gaming application. Broadcast – sign and broadcast a transaction on the blockchain in order to send data and any corresponding proof on-chain for consumption by the smart contract. Output (optional) –  send data to an external system upon the execution of a smart contract, such as relaying payment instructions to a traditional payment network or triggering actions from a cyber-physical system.

From the Introduction to Ed25519, there are some speed benefits, and some security benefits. One of the more interesting security benefits is that it is immune to several side channel attacks: No secret array indices. The software never reads or writes data from secret addresses in RAM; the pattern of addresses is completely predictable. The software is therefore immune to cache-timing attacks, hyperthreading attacks, and other side-channel attacks that rely on leakage of addresses through the CPU cache. No secret branch conditions. The software never performs conditional branches based on secret data; the pattern of jumps is completely predictable. The software is therefore immune to side-channel attacks that rely on leakage of information through the branch-prediction unit. For comparison, there have been several real-world cache-timing attacks demonstrated on various algorithms. http://en.wikipedia.org/wiki/Timing_attack

I work primarily on Windows, but I support my kids who primarily use Mac for their college education. I have used DT on Mac, IPOS, IOS for about a year. On Windows, I have been using Kinook’s UltraRecall (UR) for the past 15 years. It is both a knowledge outliner and document manager. Built on top of a sql lite database. You can use just life DT and way way more. Of course, there is no mobile companion for UR. The MS Windows echo system in this regard is at least 12 years behind.

I also think being able to self-host and export parts of your data to share with others would be great.

Good commit hygiene is considered a best practice. GitLab should encourage and enable these kinds of best practices. This feature currently creates a problem and requires workarounds that remove information, or significant manual work.

My highlights are littered with notes to self and action items - it's not all pure knowledge.

Mason Currey’s book “Daily Rituals: Women at Work.” It gives cheerful summaries about how some of the most prolific, successful artists managed their time.

The novelist and screenwriter Raymond Chandler said he avoided reading books written by someone who didn’t “take the pains” to write out the words. (It used to be common for writers to dictate into a recorder then have an assistant transcribe those words.) “You have to have that mechanical resistance,” Chandler wrote in a 1949 letter to actor/writer Alex Barris. “When you have to use your energy to put those words down, you are more apt to make them count.”

If you can’t talk yourself into using your energy to write or type something out, it’s probably not worth capturing.

There are two situations where an init-like process would be helpful for the container.

highly recommended that the resulting image be just one concern per container; predominantly this means just one process per container, so there is no need for a full init system

Try to make the Dockerfile easy to understand/read.

For example, if using apt to install the main program for the image, be sure to pin it to a specific version (ex: ... apt-get install -y my-package=0.1.0 ...)

Rebuilding the same Dockerfile should result in the same version of the image being packaged, even if the second build happens several versions later, or the build should fail outright, such that an inadvertent rebuild of a Dockerfile tagged as 0.1.0 doesn't end up containing 0.2.3.

Version bumps and security fixes should be attended to in a timely manner.

If you do not represent upstream and upstream becomes interested in maintaining the image, steps should be taken to ensure a smooth transition of image maintainership over to upstream.

Note: This repo does not publish or maintain a latest tag. Please declare a specific tag when pulling or referencing images from this repo.

Unfortunately most init systems don't do this correctly within Docker since they're built for hardware shutdowns instead. This causes processes to be hard killed with SIGKILL, which doesn't give them a chance to correctly deinitialize things.

Zombie processes should not be confused with orphan processes: an orphan process is a process that is still executing, but whose parent has died. When the parent dies, the orphaned child process is adopted by init (process ID 1). When orphan processes die, they do not remain as zombie processes; instead, they are waited on by init.

The problems that we solved are applicable to a lot of people. Most people are not even aware of these problems, so things can break in unexpected ways (Murphy's law). It's inefficient if everybody has to solve these problems over and over.

To check whether the music symbol ♫ is being displayed in a string (if it is not being displayed on some devices), you can try measuring the string width; if width == 0 then the symbol is absent.

I want to check if the String I am about to display can be displayed by my custom font.

I can't find a method to check if my Typeface can display a particular String though.

While there are many great answers regarding the "glyph not found" glyph, that won't help you actually detect it, as the text string in code will still have the character regardless of the font used to render it.

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

I want to be able to detect if the font used can display a certain character or not

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.

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:

Here is a method using the fontTools Python library (which you can install with something like pip install fonttools):

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.

Related: #45017 ActiveRecord silently triggers a rollback when return is used in the transaction block.

Just as a breadcrumb here for future readers (I found this thread when I was searching), it seems Cuprite has support for non-headless now (via Ferrum). headless: false in the options does the trick. And thanks for your work on Cuprite.

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."

“The one inhibition I felt using AnswerGarden [was] knowing that the experts were typically busy and workingon projects more important than my little application programs....

ix users were “heavy” users, accounting for 61% of the totalsessions. Heavy users often kept Answer Garden running in an iconifiedstate between uses. One heavy user reported:

Each user and each expert has incentives to work separately toward theconstruction of such a Garden. The users get to find answers, and expertscan rid themselves of commonly asked questions.

Several important considerations behind Answer Garden include:

ngineerschose not to go to the channel of the highest quality for technical informa-tion, but rather to go to the channel of highest accessibility (i.e., lowestpsychological cost). Allen [1977] argued that the psychological cost was inthe potential lack of reciprocity between giving and obtaining informationand in the status implications of admitting ignorance.

information technology can support organizational memory in twoways, either by making recorded knowledge retrievable or by makingindividuals with knowledge accessible

Out of this friction of competing ideas can comethe sort of improvisational sparks necessary for igniting organizational innovation.Thus large organizations, reflectively structured, are perhaps particularly well posi-tioned to be highly innovative and to deal with discontinuitie

Reliance on formal descriptions of work, explicit syllabuses for learning about it,and canonical groups to carry it out immediately set organizations at a disadvantage.This approach, as we have noted, can simply blind management to the practices andcommunities that actually make things happ

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.
