This isn't about writing boilerplate setter properties for each field in the model, but rather about writing methods that encapsulate the point of interaction with the database layer. View code can still inspect any field on the model and perform logic based on that, but it should not modify that data directly. We're ensuring that there is a layer at which we can enforce application-level integrity constraints that exist on top of the integrity constraints that the database provides for us.

Happy Third Birthday #24728!

Personally I think it is a very bad idea to leverage political views, even if I may share them, through software.

There's no official Chrome or Chromium package for Linux don't install it this way because it's either outdated or unofficial, both are bad. Download it from official source.

This is why for a recent Angular+Rails project we chose to use a testing stack from the backend technology’s ecosystem for e2e testing.

Rather than write new tooling we decided to take advantage of tooling we had in place for our unit tests. Our unit tests already used FactoryBot, a test data generation library, for building up test datasets for a variety of test scenarios. Plus, we had already built up a nice suite of helpers that we coud re-use. By using tools and libraries already a part of the backend technology’s ecosystem we were able to spend less time building additional tooling. We had less code to maintain because of this and more time to work on solving our customer’s pain points.

The problem domain and the data involved in this project was complicated enough. We decided that not having to worry about unknowns with the frontend end-to-end testing stack helped mitigate risk. This isn’t to say you should always going with the tool you know, but in this instance we felt it was the right choice.

This particular project team came in with a lot of experience using testing tools like RSpec and Capybara. This included integrating with additional tools like Selenium WebDriver, Chrome and Chromedriver, data generation libraries like FactoryBot, and task runners like Rake. We had less experience doing end-to-end testing with Protractor even though it too uses Selenium WebDriver (a tool we’re very comfortable with).

There are times to stretch individually and as a team, but there are also times to take advantage of what you already know.

We chose to define the frontend in one technology stack (Angular+TypeScript/JavaScript) and the backend in another (Ruby+Ruby on Rails), but both came together to fulfill a singular product vision.

For me the diagrams make it easier to talk about what the tests do without getting bogged down by how they do it.

targeting what the user actually sees

The most important guideline to give is the following: Write clean unit tests if there is actual value in testing a complex piece of logic in isolation to prevent it from breaking in the future Otherwise, try to write your specs as close to the user’s flow as possible

It’s better to test a component in the way the user interacts with it: checking the rendered template.

Or if you're looking for a core extension that adds this to the Array class, I'd recommend the facets gem (require 'facets/array/average'). Then you can just do array.average. And, from looking at the source, it turns out they do the exact same thing as the instance_eval approach above. The only difference is that it's implemented as a method—which of course already has self pointing to itself—instead of a block): def average; return nil if empty?; reduce(:+) / length.to_f; end Main advantage of this is that it's even more concise/readable and it handles the empty? case.

You can return the record directly from the UPDATE, which is much faster than calling an additional SELECT statement. Use RETURN QUERY and UPDATE with a RETURNING clause.

Users who have installed it decided to trust me, and I'm not comfortable transferring that trust to someone else on their behalf. However, if you'd like to fork it, feel free.

A litmus test on whether an option belongs to adapter config or kit config, would be to ask whether the option becomes irrelevant when you switch the adapter to static.

This function runs on every request, for both pages and endpoints, and determines the response. It receives the request object and a function called resolve, which invokes SvelteKit's router and generates a response accordingly.

that involves looking up where to find Guix's source code, `git clone`ing it, finding the Guix revision I'm currently on with `guix describe` so I can check out the same one for consistency's sake, `make`ing it, `guix environment guix`, using `pre-inst-env`, etc

Lumberjack 1.0 had a concept of a unit of work id that could be used to tie log messages together. This has been replaced by tags. There is still an implementation of Lumberjack.unit_of_work, but it is just a wrapper on the tag implementation.

Coordination: More environments require more coordination. Teams need to track which feature is deployed to which environment. Bugs need to be associated with environments. Every environment represents a particular ‘state’ of the codebase, and this has to be tracked somewhere to make sure that customers & stakeholders are seeing the right things;

I also sell Sidekiq Pro and Sidekiq Enterprise, extensions to Sidekiq which provide more features, a commercial-friendly license and allow you to support high quality open source development all at the same time.

CSS seems like the right place to put visual information. On the other hand, few would argue that image "src" should not be specified as an attribute and the height/width seem as tied to the binary image data as the "src" is.

I don't know why but they just removed some featuresAt first, you can't play this with your friend online except waiting for random matchingYou can't invite your friends to your closed room and play togheter

In some cases empty can be the simplest replacement for TCL/expect or other similar programming tools because empty:

Screen and Tmux are used to add a session context to a pseudoterminal, making for a much more robust and versatile solution. For example, each provides terminal persistence, allowing a user to disconnect from one computer and then connect later from another computer.

I should note that the issue with deletions being skipped has been fixed (the file-has-vanished errors were changed into warnings).

Clubhouse has really made a fuss around the digital world. It’s hard to imagine a person who hasn’t heard about this app, celebrities who joined it, or pranksters who already managed to confuse the audience. Taking into account the skyrocketing popularity, “how to make an app like Clubhouse” has become an urgent question in the software development business.

# +devise_for+ is meant to play nicely with other routes methods. For example, # by calling +devise_for+ inside a namespace, it automatically nests your devise # controllers: # # namespace :publisher do # devise_for :account # end

find_field finds by id, name or placeholder text - so find_field('Prefix') should find the element with matching placeholder text rather than needing xpath.

Or is this a call for mainstream operating systems and applications to get creative (read, nice tiling or splitting by default)?What if all browsers suported single page split view? So that the left side was your regular view, half width, and the right side was the continuation of the same page, where the left side ended.

Use cases, user stories, functional requirements, and visual analysis models are popular choices for requirements specification.

Sorry you’re surprised. Issues are filed at about a rate of 1 per day against GLib. Merge requests at a rate of about 1 per 2 days. Each issue or merge request takes a minimum of about 30 minutes (across at least 2 people) to analyse, put together a fix, test it, review it, fix it, review it and merge it. I’d estimate the average is closer to 3 hours than 30 minutes. Even at the fastest rate, it would take 3 working months to clear the backlog of ~1000 issues. I get a small proportion of my working time to spend on GLib (not full time).

Age of a ticket is completely irrelevant as anyone can request anything but the number of developers is limited. If you'd like to see something implemented, please consider providing a patch. Thanks!

Sorry if I sounded rude. I am using Gnome on a daily basis and am highly appreciating all the work anyone has put into it. I was just surprised when I found an AskUbuntu post from 2010 linking to this bug.

Wow 14 years. I still keep stumbling over this issue...

Clinical Data Systems to Support Public Health Practice: A National Survey of Software and Storage Systems Among Local Health Departments

In the real world, we are faced with the completely unfair constraint of being human while writing programs and while debugging them, and none of these costs can ever be reduced to zero.

Nothing about the Unix Philosophy explicitly relates to a culture of software sharing. However, it should be no mystery that it comes from the software community where we argue at length about the best way to make our programs properly Free. Software that is developed according to these principles is easier to share, reuse, repurpose, and maintain.

Write modules that solve a problem you know

One thing that would be useful to this debate an analysis of a language ecosystem where there are only "macropackages" and see if the same function shows up over and over again across packages.

JavaScript needs to fly from its comfy nest, and learn to survive on its own, on equal terms with other languages and run-times. It’s time to grow up, kid.

If JavaScript were detached from the client and server platforms, the pressure of being a monoculture would be lifted — the next iteration of the JavaScript language or run-time would no longer have to please every developer in the world, but instead could focus on pleasing a much smaller audience of developers who love JavaScript and thrive with it, while enabling others to move to alternative languages or run-times.

While various shortcomings of the standard run-time library are the obvious, immediate reason for the creation of micro-packages

As to opinions about the shortcomings of the language itself, or the standard run-times, it’s important to realize that every developer has a different background, different experience, different needs, temperament, values, and a slew of other cultural motivations and concerns — individual opinions will always be largely personal and, to some degree, non-technical in nature.

PyPy was funded by the European Union being a Specific Targeted Research Project

There used to be other backends in addition to C: Java, CSharp, and Javascript but those suffered from bitrot and have been removed.

Refactoring is a means of addressing the problem of software rot. It is described as the process of rewriting existing code to improve its structure without affecting its external behaviour.

Suppose an administrator creates a forum using open source forum software, and then heavily modifies it by adding new features and options. This process requires extensive modifications to existing code and deviation from the original functionality of that software.

cannot be run on any modern day computer or computer simulator, as it was developed during the days when LISP and PLANNER were still in development stage, and thus uses non-standard macros and software libraries which do not exist anymore

Software that is not currently being used gradually becomes unusable as the remainder of the application changes.

much software requires continuous changes to meet new requirements and correct bugs, and re-engineering software each time a change is made is rarely practical.

This creates what is essentially an evolution process for the program, causing it to depart from the original engineered design. As a consequence of this and a changing environment, assumptions made by the original designers may be invalidated, introducing bugs.

will eventually lead to software becoming faulty, unusable, or in need of upgrade.

Digital technology may contain no moving parts but it still, somehow, gets worn, splintered and corroded. It rots. It decays. The rot, though, is mostly invisible (and un-smellable). Still, one day, the thing is broken.

As of May 24, 2016, antimicro has moved from https://github.com/Ryochan7/antimicro to https://github.com/AntiMicro/antimicro. Additionally, project management has passed from Travis (Ryochan7) to the AntiMicro organization due to Travis having other interests and priorities.

D3 4.0 is modular. Instead of one library, D3 is now many small libraries that are designed to work together. You can pick and choose which parts to use as you see fit.

When markets are new and “hot”, they often follow that frenzy of dozens — if not hundreds — of entrants trying to grab market share from each other.

For the $$$ question, nothing comes to mind. These problems i'm hitting up against are larger than a contractor could solve in a few hours of work (which would be hundreds/thousands of dollars).

Yeah, can we pay money to make this go faster? Serious question.

Progress is slow though. I want to change how assets are loaded, the current implementation of "pipelines" is challenging to work with.

But we're definitely sticking with the source map idea rather than the current (Rails 3/4) behavior of including all JS and CSS files separately while in development?

Still broken, @cannikin. Nobody's on board to investigate, much less fix it. Please do dig in

Think JavaScript is your only option for the front-end? Think again. Hyperstack is a Ruby DSL, compiled by Opal, bundled by Webpack, powered by React.

Want to know how to build a taxi app that will become the next Uber or Carb? It is a reasonable question considering how convenient and cost-effective it is to use a taxi instead of maintaining your own vehicle. The best way for a cab company to ensure this convenience for customers is to build a taxi booking app.

You could also use the NodeIterator API, but TreeWalker is faster

All those 'modern' and 'super-modern' querySelectorAll("*") need to process all nodes and do string comparisons on every node.

the fastest solution because the main workload is done by the Browser Engine NOT the JavaScript Engine

markdown-it is the result of the decision of the authors who contributed to 99% of the Remarkable code to move to a project with the same authorship but new leadership (Vitaly and Alex). It's not a fork.

Posting an issue on the discussion boards for a three year old game, yesterday, I wasn't holding my breath for a reply. Earlier, this morning, a dev. responded, stating they'd look at fixing it, and it was just a few hours before it were sorted!

There’s no need to test controllers, models, service objects, etc. in isolation

Run the complete unit with a certain input set, and test the side-effects. This differs to the Rails Way™ testing style, where smaller units of code, such as a specific validation or a callback, are tested in complete isolation. While that might look tempting and clean, it will create a test environment that is not identical to what happens in production.

Everyone knows friction in software is harmful. But I think we all continually underestimate just how big an influence friction is on what people actually do and use. People don’t write long multi-tweet threads because it’s a good way to post a short essay, they do it because it’s so low friction.

Enforces better architecture

Each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details, making the language more programmer-friendly, powerful, and versatile.

provide interfaces so you don’t have to think about them

Trailblazer is an architectural pattern that comes with Ruby libraries to implement that pattern.

Whether this is the life-cycle of a <user> entity or just a sign-up function, it has to be defined and coded somewhere.

I started Trailblazer GmbH 4 years ago with my relocation from Australia back to Europe. One of our consulting clients is the central police department of a German state that has kept me busy for more than three years now.

We’re now relaunching PRO, but instead of a paid chat and (never existing) paid documentation, your team gets access to paid gems, our visual editor for workflows, and a commercial license.

And yes, at TRB GmbH, we do pay people to work on OSS

To tell you the truth, the new tracing feature was the original reason why I decided to write 2.1 and make you sit and wait in agony for years. Nevertheless, tracing is simply blowing my mind. I can’t count how many hours and angering rushs of adrenaline I’ve saved since the introduction of the wtf? method and its helpful higher-level stack trace.

There is nothing wrong with building your own “service layer”, and many companies have left the Traiblazer track in the past years due to problems they had and that we think we now fixed.

note that TRB source code modifications are not proprietary

Why is TRB licensed under LGPL, not MIT?

The LGPL allows users to use and integrate LGPL software components into their own software without being required to release the source code of their own software components. However, if users modify LGPL software components (“derivative work”), they are required to make the modified software component available under the same LGPL license. To avoid the latter with TRB, users have to comply with para. 5 LGPLv2.1: A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a “work that uses the Library”. Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. In other words: if you use the TRB libraries in your commercial applications or Open-Source projects, you’re not creating a derivative work of Trailblazer. Your software can be distributed under any terms.

Trailblazer (TRB) is an Open-Source project. Since we want to keep it that way, we decided to raise awareness for the “cost” of our work - providing new versions and features is incredibly time-consuming for us, but we love what we do.

This creates a win-win situation, you as the user have your peace of mind, and we can continue working with your funds.

Trailblazer extends the conventional MVC stack in Rails. Keep in mind that adding layers doesn't necessarily mean adding more code and complexity. The opposite is the case: Controller, view and model become lean endpoints for HTTP, rendering and persistence. Redundant code gets eliminated by putting very little application code into the right layer.

Trailblazer offers you a new, more intuitive file layout in applications.

Instead of grouping by technology, classes and views are structured by concept, and then by technology. A concept can relate to a model, or can be a completely abstract concern such as invoicing.

While Trailblazer offers you abstraction layers for all aspects of Ruby On Rails, it does not missionize you. Wherever you want, you may fall back to the "Rails Way" with fat models, monolithic controllers, global helpers, etc. This is not a bad thing, but allows you to step-wise introduce Trailblazer's encapsulation in your app without having to rewrite it.

we’re going to look how improved pattern matching and rightward assignment make it possible to “destructure” hashes and arrays in Ruby 3—much like how you’d accomplish it in, say, JavaScript

ActiveInteraction plays nicely with Rails. You can use interactions to handle your business logic instead of models or controllers.

Why is all this interaction code better? Two reasons: One, you can reuse the FindAccount interaction in other places, like your API controller or a Resque task. And two, if you want to change how accounts are found, you only have to change one place.

@adisos if reform-rails will not match, I suggest to use: https://github.com/orgsync/active_interaction I've switched to it after reform-rails as it was not fully detached from the activerecord, code is a bit hacky and complex to modify, and in overall reform not so flexible as active_interaction. It has multiple params as well: https://github.com/orgsync/active_interaction/blob/master/spec/active_interaction/modules/input_processor_spec.rb#L41
