My research internships shocked me because they expected me to tell them what I was going to work on. They gave me a crazy amount of freedom in order to do this. I got shockingly comfortable with wandering the office buildings and asking senior employees in other divisions for their time. As long as I could periodically show value, my mentors gave me free reign.

This still would not eliminate all delay, but I think this could be faster (no render blocking), and cleaner than having inline scripts scattered all over the parent document.

Question and Answer Website Development: Functionality and Best PracticesTimur YilmazTech JournalistMarketplaceProduct GuideHomeBlogEntrepreneurshipQuestion and Answer Website Development: Functionality and Best PracticesAug 25, 202117 min readSocial media is a jumping-off point for many people to get informed. Yet, on such platforms, users are more likely to voice opinions rather than share knowledge. That's when the websites to ask questions become a good help. For example, Quora's monthly active user base grew from 200 million to 300 million in 2018 alone. In 2021, the 6.6 million downloads of the Reddit app represented a 128% increase over the previous year. What is a selling point for this kind of platform and how to build one? How do they remain beneficial in a years-long run? How Q&A websites managed to survive social network dominance? Read on to find out.

I always had to set the height of them literally almost 50% taller than the content itself to accommodate for the innards growing when the form was submitted with errors (the error messaging expanded the height). If I didn’t, the submit button would get cut off making the form un-submittable.

I really hope they keep breaking it. Being the lead on a library for several years, most of the forced refactors were pretty straight forward and in almost every case made our code either more sound or easier to be consumed. Now I work on a runtime that embeds TypeScript and 3.5.1 has broken some code, thought it took me all of about 15 minutes to make the changes to adopt it, and in every case, it broke because we were being a bit loose with the types. While it didn't find any bugs, it made the code more "safe".

You can force the type system to remember each value as a literal string: const list = ['a' as 'a','b' as 'b','c' as 'c']; // infers as ('a'|'b'|'c')[]

The authors of Team Topologies suggest that we flip this law on its head. If we can make teams that map to the structure that we want our software system to be like, then we’ll succeed when Conway’s Law kicks in.

The WebSocket Protocol is designed on the principle that there should be minimal framing (the only framing that exists is to make the protocol frame-based instead of stream-based and to support a distinction between Unicode text and binary frames). It is expected that metadata would be layered on top of WebSocket by the application Fette & Melnikov Standards Track [Page 9] RFC 6455 The WebSocket Protocol December 2011 layer, in the same way that metadata is layered on top of TCP by the application layer (e.g., HTTP). Conceptually, WebSocket is really just a layer on top of TCP that does the following: o adds a web origin-based security model for browsers o adds an addressing and protocol naming mechanism to support multiple services on one port and multiple host names on one IP address o layers a framing mechanism on top of TCP to get back to the IP packet mechanism that TCP is built on, but without length limits o includes an additional closing handshake in-band that is designed to work in the presence of proxies and other intermediaries Other than that, WebSocket adds nothing. Basically it is intended to be as close to just exposing raw TCP to script as possible given the constraints of the Web. It's also designed in such a way that its servers can share a port with HTTP servers, by having its handshake be a valid HTTP Upgrade request. One could conceptually use other protocols to establish client-server messaging, but the intent of WebSockets is to provide a relatively simple protocol that can coexist with HTTP and deployed HTTP infrastructure (such as proxies) and that is as close to TCP as is safe for use with such infrastructure given security considerations, with targeted additions to simplify usage and keep simple things simple (such as the addition of message semantics).

This works nicely wherever we show authors, but after we deploy to production, the folks from other parts of the world won’t get notified anymore about their songs. Mistakes like these are easy to make when using concerns.

it's much faster—the stack frame does not have to be carried along the "thrown symbol", and no object is created. Lightweight nonlinear flow control.

Worse still is the issue of “service” layers requiring you to basically build your own ORM. To really do a backend-agnostic service layer on top of the Django ORM, you need to replace or abstract away some of its most fundamental and convenient abstractions. For example, most of the commonly-used ORM query methods return either instances of your model classes, or instances of Django’s QuerySet class (which is a kind of chained-API results wrapper around a query). In order to avoid tightly coupling to the structure and API of those Django-specific objects, your service layer needs to translate them into something else — likely generic iterables to replace QuerySet, and some type of “business object” instance to replace model-class instances. Which is a non-trivial amount of work even in patterns like Data Mapper that are designed for this, and even more difficult to do in an Active Record ORM that isn’t.

A second problem is that when you decide to go the “service” route, you are changing the nature of your business. This is related to an argument I bring up occasionally when people tell me they don’t use “frameworks” and never will: what they actually mean, whether they realize it or not, is “we built and now have to maintain and train our developers on our own ad-hoc private framework, on top of whatever our normal business is”. And adopting the service approach essentially means that, whatever your business was previously, now your business is that plus developing and maintaining something close to your own private ORM.

https://github.com/rycus86/githooks is a really option for managing hooks It is... safe (it uses an opt-in model, where it will ask for confirmation whether new or changed scripts should be run or not (or disabled)) configurable handles a lot of the details for you lets you keep your hooks nicely organized. For example:

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).

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).

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.

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.
