This isn't to say that on a case by case basis there aren't modules that are grossly overcomplicated.

he goes on to say that simple functions should not be packages because they are too small.

Small modules are extremely versatile and easy to compose together in an app with any number of other modules that suit your needs.

Onceability can be the result of the exaggerated demand for un-memorable passwords.

is Wine process virtual machine actually?

This semi-colon is added to prevent changing the code behaviour (the famous line ending with parentheses, etc) Most people will use a JS minifier If they don't, a single extra character is unlikely to change much If I'm right about all the above: Why don't we simply always add a semi-colon regardless of what the file ends with?

yeah I discovered too late that #310 exists and does that

What is the point of avoiding the semicolon in concat_javascript_sources

   (intermediate value)(...) is not a function
       at something.source.js:1

   })();

Sprockets 4: The effect of config.assets.debug does not match the rails documentation.

concatenation still occurs.

I'm kinda stuck at the moment, going around in circles. Everything is really heavily coupled. I would like to get to the point where no load is called from within processors, but i'm not sure if that's possible. Currently the API and the caching strategies are fighting me at every step of the way. I have a branch where i'm hacking through some refactoring, no light at the end of the tunnel yet though :(

still compiles everything into single CSS/JS files

Opal is a Ruby to JavaScript source-to-source compiler. It comes packed with the Ruby corelib you know and love. It is both fast as a runtime and small in its footprint.

OpenFaaS® makes it easy for developers to deploy event-driven functions and microservices to Kubernetes without repetitive, boiler-plate coding.

Hyperstack gives you full access to the entire universe of JavaScript libraries and components directly within your Ruby code.Everything you can do in JavaScript is simple to do in Ruby; this includes passing parameters between Ruby and JavaScript and even passing Ruby methods as JavaScript callbacks.There is no need to learn JavaScript, all you need to understand is how to bridge between JS and Ruby.

What is the difference between equation and formula?

In production, you will never trigger one specific callback or a particular validation, only. Your application will run all code required to create a Song object, for instance. In Trailblazer, this means running the Song::Create operation, and testing that very operation with all its side-effects.

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

Shogi is a classic game. I know many people who want to play Shogi, but the Kanji on the pieces makes it too hard to master. I have designed this Shogi with icons so anybody can learn it easily.

It can also be included as individual modules, i.e. Hashie::Extensions::MethodReader, Hashie::Extensions::MethodWriter and Hashie::Extensions::MethodQuery.

The Model macro literally does what our model! step did.

a strategy game for me is mostly about the mechanics and the replayability. I love good art and design, but function follow form!

To understand this helper, you should understand that every step invocation calls Output() for you behind the scenes. The following DSL use is identical to the one [above]. class Execute < Trailblazer::Activity::Railway step :find_provider, Output(Trailblazer::Activity::Left, :failure) => Track(:failure), Output(Trailblazer::Activity::Right, :success) => Track(:success)

For branching out a separate path in an activity, use the Path() macro. It’s a convenient, simple way to declare alternative routes

step :decide_type, Output(Activity::Left, :credit_card) => Track(:with_credit_card)

# Create the track, which would automatically create an implicit End with the same id.
Track(:with_credit_card) do
    step :authorize
    step :charge
end

class Example::ValidationErrorTrack < Trailblazer::Activity::Railway
  step :validate_model, Output(:failure) => Track(:validation_error)
  step :save,           Output(:failure) => Track(:validation_error)

  # Can't use fail here or the magnetic_to won't work and  Track(:validation_error) won't work
  step :log_validation_error, magnetic_to: :validation_error,
    Output(:success) => End(:validation_error), 
    Output(:failure) => End(:validation_error) 
end

The sole purpose to add Dev::Trace::Inspector module is to make custom inspection possible and efficient while tracing. For example, ActiveRecord::Relation#inspect makes additional queries to fetch top 10 records and generate the output everytime. To avoid this, Inspector will not call inspect method when it finds such objects (deeply nested anywhere). Instead, it’ll call AR::Relation#to_sql to get plain SQL query which doesn’t make additional queries and is better to understand in tracing output.

Feel free to pick and choose what you need for your applications.

While you could program this little piece of logic and flow yourself using a bunch of Ruby methods along with a considerable amount of ifs and elses, and maybe elsif, if you’re feeling fancy, a Trailblazer activity provides you a simple API for creating such flow without having to write and maintain any control code. It is an abstraction.

So, what can we do to check for None in our programs? You can use builtin Optional type and write a lot of if some is not None: conditions. But, having null checks here and there makes your code unreadable.

Return None. That’s evil too! You either will end up with if something is not None: on almost every line and global pollution of your logic by type-checking conditionals, or will suffer from TypeError every day. Not a pleasant choice.

Writing code in this style is tedious and error-prone.

Monads provide an elegant way of handling errors, exceptions and chaining functions so that the code is much more understandable and has all the error handling, without all the ifs and elses.

It’s definitely better than littering our code with endless if-statements.

As you can see, we end up with a lot of boilerplate if-statements. The code is more verbose. And it’s difficult to follow the main logic.

polymorphic method inside shape class, its possible to discriminate them. without if’s.

Instead of dealing with a mix of before_filters, Rack-middlewares, controller code and callbacks, an endpoint is just another activity and allows to be customized with the well-established Trailblazer mechanics.

The bare bones operation without any Trailblazery is implemented in the trailblazer-operation gem and can be used without our stack.

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.

Only use what you like.

you can pick which layers you want. Trailblazer doesn't impose technical implementations

The new 2.1 version comes with a few necessary but reasonable changes in method signatures. As painful as that might sound to your Rails-spoiled ears, we preferred to fix design mistakes now before dragging them on forever.

account.first_name = first_name if first_name.present? account.last_name = last_name if last_name.present?

Almost always form objects wrap existing model or two.

@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

The assert method is used by all the other assertions. It pushes the second parameter to the list of errors if the first parameter evaluates to false or nil.

I like this idea a lot. I have had problems too with having multi-parameters assignments depending so heavily on active record.

I do think it's a common pattern that should be solved, and I am probably going to try and solve it as a Gem as opposed to simply writing code that we use in our code base

My only concern with this approach is that if someone calls #valid? on the form object afterwards, it would under the hood currently delete the existing errors on the form object and revalidate. The could have unexpected side effects where the errors added by the models passed in or the service called will be lost.

My concern with this approach is still that it's somewhat brittle with the current implementation of valid? because whilst valid? appears to be a predicate and should have no side effects, this is not the case and could remove the errors applied by one of the steps above.

I find reform's implementation a bit too complicated too (lots of layers of abstraction, including going through the representable gem for a lot of things)

I have developed a simple pattern that copies errors from the model or the service into the form object so that the view can still use those errors

An additional usecase is where we would like to update multiple records

Some developers found work arounds by using virtual attributes to # skip validators

Writing the uniqueness validations yourself is easy so I felt it was better to leave this up to the developer

I found the code a little bit complicated. Why to instanciate instance variables in this class instead to do a hash that could be used like this form.models[:first_model]; form.model[:second_model]?

It does seem a bit like class notes and is *too* simplified to really be of much practical use though.

From having the DLC only items be both constantly in your face and the kind of things you should really have access to as a base (medium sized building, most of the decorations etc) to the maps layout being seemingly purposefully made to be agravating, everytme I tried to play and like this game I got spit in the face by the devs

Patreon is a good example of why generic community platforms are not the future. You could certainly say that Patreon is already at the center of content, social, and commerce. But of course, Patreon has for years been getting unbundled into A, B, and C type businesses. The reason for Patreon’s erosion is that its product design is totally unsuitable for all three use cases: it’s a bad brand platform, a bad content platform, and a bad social platform. Patreon is a classic case of what Venkatesh Rao calls “Too Big to Nail,” and businesses that try to follow in its stead will face similar challenges.

Yes, i'm trying to find the union of two relations

You use grid-area, so the place for the side nav is allocated at start. If you hide (or even delete) the side nav, that won't change anything about this. You have to do a little trick: Set the width for the first column to 0 and change the grid-gap because otherwise you will have a (not needed) gap at the left.

Setting up docker-ce

it still hangs when installing

Ok, fixed it by upgrading docker

So, what I've discovered in a meanwhile. It was an ubuntu-docker issue. Recently I upgraded my ubuntu from 16.04 to 18.04. This change seems to be incompatible with the docker version I had, 1.11.0.

As you installed a development release (17.04) that had only a 9-month life span and had an End of Life (EOL) in Jan 2018, there is no way to upgrade it to 17.10 as that went EOL back in July 2018. So as you're stuck with a release without an upgrade path (as you cannot skip versions)

Situation: you have a single line of text in a flex child element. You don’t want that text to wrap, you want it truncated with ellipsis (or fall back to just hiding the overflow). But the worst happens. The unthinkable! The layout breaks and forces the entire flex parent element too wide. Flexbox is supposed to be helping make layout easier!

the bloody mount points. I couldn't believe that when I realised what was going on. I got the wire brush and dettol out and scraped it off my drive. Never, ever again.

Plus, have you seen how many loopback mounting points it creates? "df" becomes very hard to use as it buries your actual drives with it's own. One for the daemon, one for GTK, one for Gnome, one for each of the snaps you have installed....

The strangest "quirk" I had was that I couldn't get the web browser to save a file directly to an attached, encrypted drive. Permissions problem. So I had to save to an interim folder then move it across by hand. Utter pain.

It appears that Canonical is continuing it's vice grip of unliateral, maybe dictatorial control on the development of Snap to the benefit of Ubuntu, but to the detriment of groups like Linuxmint, and all other non-Ubuntu based Linux distributions - like CentOS/Redhat, Suse/openSuSe, Solus, Arch/Manjaro, PCLinuxOS, etc, that are pushing Flatpak as a truly cross-distro application solution that works equally well and non-problematic for all. .

What's wrong here is Canonical trying to position itself as a powerhouse and ascertain control over Linux users.

See also BMW and Tesla owners. If Tesla does become the largest US-based carmaker, many of the buyers will, I'm sure, think of reasons to move onto something else.

If we're not careful, it could become the new 'systemd' problem It probably already is. I don't want to sound too Stallman, but this is the inevitable "company" influence you'll always have. Companies do have their objectives which they will pursue determinedly, since they are not philanthropic (no judgment, just observation). Systemd and Red Hat. Nvidia and their drivers. Google and Android. Apple and iOS. Manufacturers with MS only support. And Canonical also has a history there: the Amazon links, Unity, Mir, and now snap.

I have nothing against snap in theory, but spamming my mounts, processes, and filesystem is just too darn much

What we didn't want it to be was for Canonical to control the distribution of software between distributions and 3rd party editors, to prevent direct distribution from editors, to make it so software worked better in Ubuntu than anywhere else and to make its store a requirement,"

Basically the typescript compiler emits no code for interfaces, so webpack can not find them in the compiled module; except when a module consists of only interfaces. In that case the module will end up completely empty and then webpack will not investigate the exports.

Knowing exactly what happens in your application can mean the difference between feeling in full control or experiencing deep frustration. Personally, unknowns drive me crazy, which in turn often leads to all sorts of experiments and/or debug sessions.

The CSS Zen Garden era was hugely inspirational to many.

Repeatedly posting in this thread that there are problems, won’t actually get anything fixed.

The “no-snaps” ship already sailed years ago…you folks missed that boat. It’s too late to wish for a return to the past. Snaps in Ubuntu have been happening for years already, and will continue regardless of any opinions expressed here.

You may find that your application requires a layout that differs slightly from your regular application layout to support one particular controller. Rather than repeating the main layout and editing it, you can accomplish this by using nested layouts (sometimes called sub-templates).

The change is too consequential to be developed in situ.

Can we just forward/bubble all events emitted by the underlying input element?

@monkeythedev can your work be used already? I would suggest not yet, i'm still doing core changes every day

If I understand the problem correctly, just changing the imports to point to svelte/internal isn't enough because they could still point to different packages depending on how your components are bundled. It solved your specific issue, but if you had two completely unrelated Svelte components compiled to vanilla javascript bundled with Svelte, you'd still hit issues with mismatching current_component when using slots or callbacks.

It sounds like another case of multiple svelte/internal modules? I think we need to look into reworking how svelte/internal keeps track of the current component since it breaks when mixing components not bundled with the app. It sounds like we need to find a way to pass Svelte's internal runtime state when instantiating components, since slots and callbacks end up mixing different svelte/internal together.

I’m fan of maps (in real life and in games), and the map play here is interesting

I'm still calling this v1.00 as this is what will be included in the first print run.

A Chrome Extension designed with one intention: Increase the speed and privacy of your web browsing by skipping tracking redirects and removing the tracking parameters from URLs to keep them short and cleaner for sharing, bookmarking, etc.

It is impossible to rebuild the base from the Dockerfile as the 3rd party dependencies have changed significantly since 8 months ago when the base was last built. The tags for my base image have been overwritten and I can only restore them from a descendant image. With Docker 1.8 I simply pulled the descendant image, tagged the base layer and I was done. With Docker 1.10+ I'd need to save, then manually construct the base image descriptor and reload it. Doable but sad that it's far more complex.

Is anything like this possible with the new setup?

Unfortunately, this image was built months ago. No one has the build any more. We are left with a descendant image that has all the original content but on lower layers.

is there a way we can specify for image build layers to be included in the pull?

Sorry, I don't totally know how the internals work, but does there currently exist a workaround? By that I mean, can I pull an image, then run it at a layer other than the top layer? (I basically use this for testing purposes, its certainly possible to build the image myself then do it, but its slightly less convenient)

So I propose having the repo in place, and using it for targeted proposals where we really want feedback from early users, and hold off formalising anything more until early next year, as you said.

How about renaming this to something more meaningful:

Don't you hate to repeat yourself? For example, I hate working on anything related to user authentication or authorization that isn't directly related to the system I'm working on. I see it as necessary evil, an accidental complexity.

It looks like you just deleted our lovely crafted issue template. It was there for good reasons. Please help us solving your issue by answering the questions asked in this template. I'm closing this. Please either update the issue with the template and reopen, or open a new issue.

@evilebottnawi Closing the issue because I removed the template looks like excessive bureaucracy.

Obviously we shouldn't rush into anything. But changes like these are best made earlier on in a project's lifecycle, so I'm eager to hear what people think so that we can start making some progress.

In principle, this information is already available through other means, but it is actually a fair amount of work to gather it in this form, and I think it could be useful to open it up to programmatic consumption.

To be honest, I'm not sure what networking activity docker-compose is doing directly vs. what the docker daemon is doing.

Focus on your application: forget about forms details like I'm dirty, field touched...

You can try to build a solution to tackle these issues on your own, but it will cost you time and money... why not use a battle-tested solution to handle all this complexity?

If you want to implement a form with a superb User Experience, you have to take care of many variables:

Form validation can get complex (synchronous validations, asynchronous validations, record validations, field validations, internationalization, schemas definitions...). To cope with these challenges we will leverage this into Fonk and Fonk Final Form adaptor for a React Final Form seamless integration.

Managing Form State (holding field information, check if a control has been touched, if the user has clicked the submit button, who owns the current focus...) can be tedious and prone to errors. We can get help from React Final Form to handle these challenges for us.

But it sounds like the library could use some way to setTouched()

I don't want Svelte to go out of its way to try to catch all these edge cases. It would require lots of fragile heuristics in the compiler. I want a solid compiler I can trust, not something magic but often out of service. I want it the simplest possible.

Especially when rollup is configured with multiple outputs, I find this particular onwarn to be helpful in reducing warning clutter. It just displays each circular reference once and doesn't repeat the warning for each output:

I think my personal preference would be to see them all at once. Or maybe limit it to up to 10 messages and then list the count of how many more messages were not displayed. Pick your reaction

Another thing we could do to limit output would be to only every show the first circular dependency warning. I think we already do this for other types of warnings. Then you would need to tackle the warnings one-by-one, though.

It looks like your links for "this" and "that" no longer work, and I'd be really curious to see.

Wondering how to get field state from multiple fields at once? People coming from Redux-Form might be wondering where the equivalent of Redux Form's Fields component is, as a way to get state from several fields at once. The answer is that it's not included in the library because it's so easy to write one recursively composing Field components together.

"doesn't work" is meaningless

One of the primary tasks of engineers is to minimize complexity. JSX changes such a fundamental part (syntax and semantics of the language) that the complexity bubbles up to everything it touches. Pretty much every pipeline tool I've had to work with has become far more complex than necessary because of JSX. It affects AST parsers, it affects linters, it affects code coverage, it affects build systems. That tons and tons of additional code that I now need to wade through and mentally parse and ignore whenever I need to debug or want to contribute to a library that adds JSX support.

Furthermore, JSX encourages bad non-dry code. Having seen a lot of JSX over the past few months, its encourages copypasta coding.

However, as a developer that uses JSX, I find it too useful/concise to give up in the name of syntax purity, especially when I know that what it translates to is still very isolated and computationally pure.

Compare that with the current recommended way to add/remove fields in an array, which is very verbose and boilerplatey:

Incurring high-cost changes isn't evolutionary design-it's oscillation caused by poor planning and requirements specification on a high cost-of-change component-it tips the anticipation/adaptation balance too far towards adaptation.

I don't think we want the cookbook to become a collection of tutorials regarding how to use certain libraries and tools with svelte. A set of more generic recipes or deep dives into topics would probably serve people better and have broader application.

emphasized the disutility of 1:1 maps and other overly detailed models: "A model which took account of all the variation of reality would be of no more use than a map at the scale of one to one."

We are very close to full inline components (with css, js logic, and templates).

always end up with a boilerplate function somewhere, which feels hacky.

It provides several capabilities that are difficult to achieve with React alone, while being compatible with the newest features of React.

I'm not sure I understand the problem, everything you are describing is already possible.

focuses way too much on the getter/tracking part of the equation which is really the part you want reduce the mental bandwidth on
