I was pleasantly surprised by Svelte's templating; in the past I've found templating languages overwhelming and inflexible, but Svelte offers just the right amount of templating whilst enabling you to use JavaScript too.

according to Hao, Mark Zuckerberg wants to increase the number of people who log into Facebook six days a week. I’m not going to get into whether this is good or bad here, but it certainly shows that what you are doing, and how you are doing it, is very important to Facebook.
Can we leverage these data points to follow a movement like Meatless Monday to encourage people to not use Facebook two days a week to cause this data analysis to crash?
Anything that is measured can be gamed. But there's also the issue of a moving target because Facebook will change it's target which then means the community activism will need to change it's target as well. (This may be fine if the point is community engagement and education as the overall mission, in which case the changing target continually engages people and brings in new people to consider what is happening and why.)

Reminded of Chapter 11 in The Odyssey:
I am likely going to retire this year and I find resonance in this as it appears that I will be accepting a "voluntary" buyout at the end of this fiscal year. My long sea journey, 25 years worth in teaching, will be officially over. Hence...the appeal to propitiate the gods, to let all the pain go, to ask forgiveness of the implacable Poseidon.

Long before the internet, and even national level newspapers, Franklin understood the power of the written word. His, and other like minded individual’s words were distributed in the form of pamphlets, that extolled their ideas on liberty and justice, and spread those words to all who were interested.

he goes on to talk about third party problems and how you're never guaranteed something is written correctly or that even if it is you don't know if it's the most optimal solution

Write modules for publication, even if you only use them privately. You will appreciate documentation in the future.
-
Second, I don't agree that there are too many small modules. In fact, I wish every common function existed as its own module. Even the maintainers of utility libraries like Underscore and Lodash have realized the benefits of modularity and allowed you to install individual utilities from their library as separate modules. From where I sit that seems like a smart move. Why should I import the entirety of Underscore just to use one function? Instead I'd rather see more "function suites" where a bunch of utilities are all published separately but under a namespace or some kind of common name prefix to make them easier to find. The way Underscore and Lodash have approached this issue is perfect. It gives consumers of their packages options and flexibility while still letting people like Dave import the whole entire library if that's what they really want to do.

non-regression testing
That would probably be a better name because you're actually testing/verifying that there hasn't been any regression.
You're testing for the absence of regression. But I guess testing for one also tests for the other, so it probably doesn't matter. (If something is not true you know it is false, etc.)

here is my set of best practices.I review libraries before adding them to my project. This involves skimming the code or reading it in its entirety if short, skimming the list of its dependencies, and making some quality judgements on liveliness, reliability, and maintainability in case I need to fix things myself. Note that length isn't a factor on its own, but may figure into some of these other estimates. I have on occasion pasted short modules directly into my code because I didn't think their recursive dependencies were justified.I then pin the library version and all of its dependencies with npm-shrinkwrap.Periodically, or when I need specific changes, I use npm-check to review updates. Here, I actually do look at all the changes since my pinned version, through a combination of change and commit logs. I make the call on whether the fixes and improvements outweigh the risk of updating; usually the changes are trivial and the answer is yes, so I update, shrinkwrap, skim the diff, done.I prefer not to pull in dependencies at deploy time, since I don't need the headache of github or npm being down when I need to deploy, and production machines may not have external internet access, let alone toolchains for compiling binary modules. Npm-pack followed by npm-install of the tarball is your friend here, and gets you pretty close to 100% reproducible deploys and rollbacks.This list intentionally has lots of judgement calls and few absolute rules. I don't follow all of them for all of my projects, but it is what I would consider a reasonable process for things that matter.
-
That said, I wish more people would talk both sides. Yes, every dependency has a cost. BUT the alternatives aren't cost free either. For all the ranting against micropackages, I'm not seeing a good pro/con discussion.

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.
-
We standardize on a finite subset of JS (such as asm.js) — and avoid the endless struggle through future iterations of the JavaScript language, competing super-sets and transpilers
asm.js and RPython sound similar (restrictive subsets)

Normally you should not register a named module, but instead register as an anonymous module: define(function () {}); This allows users of your code to rename your library to a name suitable for their project layout. It also allows them to map your module to a dependency name that is used by other libraries.

I don't understand why this isn't being considered a bigger deal by maintainrs/the community. Don't most Rails developers use SCSS? It's included by default in a new Rails app. Along with sprockets 4. I am mystified how anyone is managing to debug CSS in Rails at all these days, that this issue is being ignored makes sprockets seem like abandonware to me, or makes me wonder if nobody else is using sprockets 4, or what!
-
I don't myself understand what's going on, it clearly has something to do with source maps, but may also have to do with other sprockets changes.
-
I don't really understand what's going on. Clearly source maps have something to do with it -- a source map feature that doesn't handle SCSS very well, apparently.
-
Is there a PR to... something? sassc-rails? That would make the patch not necessary? (I don't know if there's any good way to monkey-patch that in, I think you have to fork? So some change seems required...) Should the defaults be different somehow? This is very difficult to figure out.
-
I'm not sure about all consequences of my change and this is very complex.

we want source maps in production (like DHH)
-
I totally understand that there may be a majority still considering this a bad practice and thus keeping it disabled by default in production seem ok. But there could at least be an option to enable it for people who want to, no?
-
After waiting years for sprockets to support this we were very happy to see that sprockets 4 officially added support (thanks ), but then when trying to upgrade we noticed there's actually no way to use it in production... (without brittle hacks mentioned above).
-
The only place I can find it is in the sprockets-rails gem. javascript_include_tag calls this: def find_debug_asset(path) if asset = find_asset(path, pipeline: :debug) raise_unless_precompiled_asset asset.logical_path.sub('.debug', '') asset end end
-
It seems I'm in the minority, and Sprockets seems to already pretty far along in the beta process, so at most we should add a configuration option to enable it for static compilation.

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 :(

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
-
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.

This is the story of how a bill to save the vote and preserve a semblance of democracy for millions of Americans died at the hands of an intransigent, reactionary minority in the Senate, which used the filibuster to do its dirty work
The author starts off by personifying "the bill" as something that was supposed to save millions of Americans, but rather was killed by Senators. He immediately provides a brief overview of the claim of his essay before developing his narrative. This way, the audience gets a glimpse of the issue that the author will tackle. Also, by using words such as "intransigent and reactionary", the audience already understands that the author is going to be criticizing the senators for their action.

For branching out a separate path in an activity, use the Path() macro. It’s a convenient, simple way to declare alternative routes
Seems like this would be a very common need: once you switch to a custom failure track, you want it to stay on that track until the end!!!
The problem is that in a Railway, everything automatically has 2 outputs. But we really only need one (which is exactly what Path gives us). And you end up fighting the defaults when there are the automatic 2 outputs, because you have to remember to explicitly/verbosely redirect all of those outputs or they may end up going somewhere you don't want them to go.
The default behavior of everything going to the next defined step is not helpful for doing that, and in fact is quite frustrating because you don't want unrelated steps to accidentally end up on one of the tasks in your custom failure track.
And you can't use
failfor custom-track steps becase that breaksmagnetic_tofor some reason.I was finding myself very in need of something like this, and was about to write my own DSL, but then I discovered this. I still think it needs a better DSL than this, but at least they provided a way to do this. Much needed.
For this example, I might write something like this:
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 endI guess that's not much different than theirs. Main improvement is it avoids ugly need to specify end_id/end_task.
But that wouldn't actually be enough either in this example, because you would actually want to have a failure track there and a path doesn't have one ... so it sounds like Subprocess and a new self-contained ProcessCreditCard Railway would be the best solution for this particular example... Subprocess is the ultimate in flexibility and gives us all the flexibility we need)
But what if you had a path that you needed to direct to from 2 different tasks' outputs?
Example: I came up with this, but it takes a lot of effort to keep my custom path/track hidden/"isolated" and prevent other tasks from automatically/implicitly going into those steps:
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) endputs Trailblazer::Developer.render o Reloading... #<Start/:default> {Trailblazer::Activity::Right} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=validate_model> #<Trailblazer::Activity::TaskBuilder::Task user_proc=validate_model> {Trailblazer::Activity::Left} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=log_validation_error> {Trailblazer::Activity::Right} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=save> #<Trailblazer::Activity::TaskBuilder::Task user_proc=save> {Trailblazer::Activity::Left} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=log_validation_error> {Trailblazer::Activity::Right} => #<End/:success> #<Trailblazer::Activity::TaskBuilder::Task user_proc=log_validation_error> {Trailblazer::Activity::Left} => #<End/:validation_error> {Trailblazer::Activity::Right} => #<End/:validation_error> #<End/:success> #<End/:validation_error> #<End/:failure>Now attempt to do it with Path... Does the Path() have an ID we can reference? Or maybe we just keep a reference to the object and use it directly in 2 different places?
class Example::ValidationErrorTrack::VPathHelper1 < Trailblazer::Activity::Railway validation_error_path = Path(end_id: "End.validation_error", end_task: End(:validation_error)) do step :log_validation_error end step :validate_model, Output(:failure) => validation_error_path step :save, Output(:failure) => validation_error_path endo=Example::ValidationErrorTrack::VPathHelper1; puts Trailblazer::Developer.render o Reloading... #<Start/:default> {Trailblazer::Activity::Right} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=validate_model> #<Trailblazer::Activity::TaskBuilder::Task user_proc=validate_model> {Trailblazer::Activity::Left} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=log_validation_error> {Trailblazer::Activity::Right} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=save> #<Trailblazer::Activity::TaskBuilder::Task user_proc=log_validation_error> {Trailblazer::Activity::Right} => #<End/:validation_error> #<Trailblazer::Activity::TaskBuilder::Task user_proc=save> {Trailblazer::Activity::Left} => #<Trailblazer::Activity::TaskBuilder::Task user_proc=log_validation_error> {Trailblazer::Activity::Right} => #<End/:success> #<End/:success> #<End/:validation_error> #<End/:failure>It's just too bad that:
- there's not a Railway helper in case you want multiple outputs, though we could probably create one pretty easily using Path as our template
- we can't "inline" a separate Railway acitivity (Subprocess "nests" it rather than "inlines")
-
step :direct_debit
I don't think we would/should really want to make this the "success" (Right) path and :credit_card be the "failure" (Left) track.
Maybe it's okay to repurpose Left and Right for something other than failure/success ... but only if we can actually change the default semantic of those signals/outputs. Is that possible? Maybe there's a way to override or delete the default outputs?

Personally, I'm starting to think that the feature where it automatically adds xray.js to the document is more trouble than it's worth. I propose that we remove that automatic feature and just make it part of the install instructions that you need to add this line to your template/layout: <%= javascript_include_tag 'xray', nonce: true if Rails.env.development? %>

Now that I've thought more about it, I honestly think the auto-adding the script feature is overrated, over-complicated, and error-prone (#98, #100), and I propose we just remove it (#110).

Have you ever felt like a framework was getting in the way instead of helping you go faster? Maybe you’re stuck on some simple task that would be easy to do manually, but your framework is making you jump through configuration hoops. I end up getting lost in a sea of documentation (or no documentation), and the search for that one magical config key takes just a tad bit too long. It’s a productivity sink, and worse than the time delay it adds to my frustration throughout the day.

- Without waiting for judicial approval, the board pulled nineelementary schools out of the busing program this summer, reducing to 10 percent thenumber of students being bused.
- Although high school diploma standards have been eased in recent years, the number ofeligible students graduating from high school has slipped from three-quarters in 1990 totwo-thirds today. In the past decade, the number of disciplinary suspensions has tripled, to7,183 in 1994.
- "We lost 7,000 students in the summer of 1975," recalled Naomi L. Bradford, a white busingopponent who was elected head of the school board in 1985. "In the fall, we lost 100students a week -- probably as soon as their homes were sold."
- Denver's school board deliberately segregated schools through a strategyof building schools and shifting attendance boundaries. Largely black schools routinelyended up with the oldest books and the youngest teachers.
- Black and Hispanic men and womenare in the City Council, the schoolboard, the State Legislature andother political positions."
- In 1968, the year before busing began, 63,398 white students attended Denver publicschools. Last year, there were 18,000. Black enrollments have remained about 13,000, whileHispanic enrollments have increased to 28,283 from 18,611.

Let’s start with the same number dividing example, which returns 0 when the error happens. Maybe instead we can indicate that the result was not successful without any explicit numerical value?
-
You can use container values, that wraps actual success or error value into a thin wrapper with utility methods to work with this value. That’s exactly why we have created @dry-python/returns project. So you can make your functions return something meaningful, typed, and safe.
-
Not all cases can be covered and easily restored. And sometimes when we will reuse this function for different use-cases we will find out that it requires different restore logic.
-
You still need to have a solid experience to spot these potential problems in a perfectly readable and typed code.
-
So, the sad conclusion is: all problems must be resolved individually depending on a specific usage context. There’s no silver bullet to resolve all ZeroDivisionErrors once and for all. And again, I am not even covering complex IO flows with retry policies and expotential timeouts.

An operation has two invocation styles. This is the only difference to an Activity.
-
-
github.com github.com
-
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.
-
-
trailblazer.to trailblazer.to
-
Endpoint is the missing link between your routing (Rails, Hanami, …) and the “operation” to be called. It provides standard behavior for all cases 404, 401, 403, etc and lets you hook in your own logic like Devise or Tyrant authentication, again, using TRB activity mechanics.
-
What this means is: I better refrain from writing a new book and we rather focus on more and better docs.
I'm glad. I didn't like that the book (which is essentially a form of documentation/tutorial) was proprietary.
I think it's better to make documentation and tutorials be community-driven free content
-
Using a terminus to indicate a certain outcome - in turn - allows for much stronger interfaces across nested activities and less guessing! For example, in the new endpoint gem, the not_found terminus is then wired to a special “404 track” that handles the case of “model not found”. The beautiful thing here is: there is no guessing by inspecting ctx[:model] or the like - the not_found end has only one meaning!
-
A major improvement here is the ability to maintain more than two explicit termini. In 2.0, you had the success and the failure termini (or “ends” as we used to call them). Now, additional ends such as not_found can be leveraged to communicate a non-binary outcome of your activity or operation.
-
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.
-
To make it short: we returned to the Rails Way™, lowering our heads in shame, and adhere to the Rails file and class naming structure for operations.
-
It’s so simple that I sometimes wonder why it took years to develop it!
-
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.

In Trailblazer, models are completely empty. They solely contain associations and finders. No business logic is allowed in models.
-
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.

The Quest for Truth
The quest for Truth is everywhere and not limited to the economic topics linked here. This is just a topic that started a thought process where I had access to a convenient tool (Hypothesis) to bookmark my thoughts and research.
Primary thought is: The Quest for Truth. Subcategories would provide a structured topic for the thought. In this case the subcategory would be: US Economy, Inflation
The TRUTH is a concept comprised of inconsistencies and targets that frequently move.
Targets (data, methods, people, time, semantics, agenda, demographic, motive, means, media, money, status) hold a position in time long enough to fulfill a purpose or agenda. Sometimes they don't consciously change, but history over time shines light and opens cracks in original narrative that leads to new truth's, real or imagined.
Verifying and validating certain Truth is very difficult. Why is That?

A popular strategy for bootstrapping networks is what I like to call “come for the tool, stay for the network.” The idea is to initially attract users with a single-player tool and then, over time, get them to participate in a network. The tool helps get to initial critical mass. The network creates the long term value for users, and defensibility for the company.
This is an interesting and useful strategy. I've heard the idea several times before.
I'm curious if this is the oldest version of it? I have to imagine that there are earlier versions of it dating back to 2011 or 2012 if not earlier.

To give a little more context, structures like this often come up in my work when dealing with NoSQL datastores, especially ones that rely heavily on JSON, like Firebase, where a records unique ID isn't part of the record itself, just a key that points to it. I think most Ruby/Rails projects tend towards use cases where these sort of datastores aren't appropriate/necessary, so it makes sense that this wouldn't come up as quickly as other structures.

But ActiveModel doesn't support out of the box argument parsing, e.g. having a datetime attribute be a datetime attribute and a boolean attribute be a boolean attribute.
Doesn't it now, with the (newer)
ActiveModel::AttributesAPI?

Examples of different ways of defining forms
Wow, that's a lot of different ways.
The inline_form way in particular seems interesting to me, though it's worth noting that that method is just an example, not actually part of this project's code, so it's not really a first-class option like the other options.

The press release also quoted a UA assistant provost for institutional research who explained that while the swipes of student ID cards were not used in the current student retention analytics, about 800 other data points were
The research in questions was not currently being used by the institution to improve rention, but other student data was already being used for that purpose
-
The researcher noted that the data she had used had been anonymized before she was given access to it—however, she added that if/when her research might inform the ongoing efforts to improve student retention, the student’s personal details would be “shared” with the students' academic advisers.
The data was anonymized before she was given access, but she admitted that there might be interest in sharing students' personal details with academic advisors
-
She then used that data to create large networks mapping which students interacted with one another and how often.
The researcher sought to track the personal interactions of students with one another

On the university’s website, a press release
The university share the finding of the research after the fact
-
At the University of Arizona, for example, a researcher analyzed the swipes of student ID cards at locations across campus, “to see what they reveal about students' routines and relationships, and what that means for their likelihood of returning to campus after their freshman year.”
Fact. Student ID Cards Collect Data Fact. A researcher was given access to this data for her own purposes.

We are still open to the idea but the implementation should leverage the attributes API introduced in Rails 5.2 in Active Model.

If you don't understand both sides of an issue, you cannot make an intelligent choice; in fact, if you don't understand all the ramifications of your actions, you're not designing at all. You're stumbling in the dark.

Stating that some language feature or common programming idiom (like accessors) has problems is not the same thing as saying you should never use them under any circumstances.

By the same token, marketing or political incentives often push design idioms

I think maybe the terms we're using are a bit confusing.

It makes me happy to see people actually think about things and not just accept a shitty API.

with ActiveForm-Rails, validations is the responsability of the form and not of the models. There is no need to synchronize errors from the form to the models and vice versa.
But if you intend to save to a model after the form validates, then you can't escape the models' validations:
either you check that the models pass their own validations ahead of time (like I want to do, and I think @mattheworiordan was wanting to do), or you have to accept that one of the following outcomes is possible/inevitable if the models' own validations fail:
- if you use
object.savethen it may silently fail to save - if you use
object.savethen it will fail to save and raise an error
Are either of those outcomes acceptable to you? To me, they seem not to be. Hence we must also check for / handle the models' validations. Hence we need a way to aggregate errors from both the form object (context-specific validations) and from the models (unconditional/invariant validations that should always be checked by the model), and present them to the user.
What do you guys find to be the best way to accomplish that?
I am interested to know what best practices you use / still use today after all these years. I keep finding myself running into this same problem/need, which is how I ended up looking for what the current options are for form objects today...

DSLs can be problematic for the user since the user has to manage state (e.g. am I supposed to call valid? first or update_attributes?). This is exactly why the #validate is the only method to change state in Reform.
-
The reason Reform does updating attributes and validation in the same step is because I wanna reduce public methods. This is to save users from having to remember state.
I see what he means, but what would you call this (tag)? "have to remember state"? maybe "have to remember" is close enough
Or maybe order is important / do things in the right order is all we need to describe the problem/need.
