Here's example code which works around the lack of a ??= operator in the wild:

However, this idiom is only an approximation, and introduces subtle bugs when we try to allow false values:

However, in order to tell InheritedResources that it really failed, you need to add errors to your model.

I've just experienced the same issue with confirmation links being executed in a sent email before the user has received them and invalidating the link. I got around the issue by modifying the page the URL links to. I've added a Confirm button on the page which the user has to click to confirm their email and this works nicely.

Especially users working with Microsoft Office 365 and therefore Outlook noticed very often that login is not possible. Upon closer analysis, it was found that the MS/Bing crawlers are particularly persistent and repeatedly call the reset links, regardless of server configuration or the like. For this reason, a text field was implemented in the backend via the Drupal State API, in which selected user agents (always one per line) can be entered. These are checked by 'Shy One Time', in case of a hit a redirect to the LogIn form with a 302 status code occurs, the reset link is not invalidated.

Another suggestion some senders are trying is to set up a “stealth” link, that human readers won’t see or click on but that parsing software might. Clicks on that link are a sign that the click was not done by the recipient.

As you've seen, there is no DM system, but you can invite users to chat directly. More generally, consider commenting on the question itself and @-ing the user who made the edit(s). To my understanding, this should work, and it may allow for a quick explanation that doesn't require going in to chat.

One way to potentially get around this is to have an object that simple holds a class and overrides the === operator to make case work properly:

Some frameworks call this “template inheritance”. In this example, we might say that the application layout “inherits from” or “extends” the base layout. In Rails, this is known as nested layouts, and it is a bit awkward to use. The standard Rails practice for nested layouts is complicated and involves these considerations

But what if you want to reuse one layout within another?

It can sort of be achieved with the current setup (via labels), but I really like where this is going -- turning everything into a similar "object" in a hierarchy rather than separate standalone structures that connect and get "labeled" to show what they are.

Enable ActiveRecord unsigned integers to use 8 bytes instead of 4. This fixes the ActiveModel::RangeError problem where AR models with perfectly fine 8 bytes primary keys are taken for ActiveModel::Type::Integer with a default limit of 4 bytes.

In development, I was able to reset the exponential cool down by removing the g_state cookie. One method for this might be to add a development-only "Clear Google One Tap Cookie" link that run an server-side action to remove the g_state cookie and then redirect back to the previous page.

sums = [0] (1..gains.length).each do |i| sums[i] = sums[i - 1] + gains[i - 1] end could, if scan was introduced, be replaced with: sums = gains.scan_left(0, &:+)

I ran into the same problem and never really found a good answer via the test objects. The only solution I saw was to actually update the session via a controller. I defined a new action in one of my controllers from within test_helper (so the action does not exist when actually runnning the application). I also had to create an entry in routes. Maybe there’s a better way to update routes while testing. So from my integration test I can do the following and verfiy: assert(session[:fake].nil?, “starts empty”) v = ‘Yuck’ get ‘/user_session’, :fake => v assert_equal(v, session[:fake], “value was set”)

I make a file named: app/models/active_storage/attachment.rb. Because it's in your project it takes loading precedence over the Gem version. Then inside we load the Gem version, and then monkeypatch it using class_eval: active_storage_gem_path = Gem::Specification.find_by_name('activestorage').gem_dir require "#{active_storage_gem_path}/app/models/active_storage/attachment" ActiveStorage::Attachment.class_eval do acts_as_taggable on: :tags end The slightly nasty part is locating the original file, since we can't find it normally because our new file takes precedence. This is not necessary in production, so you could put a if Rails.env.production? around it if you like I think.

As far as I see the current version of arel gem is not support FROM keyword for the sql query. You can generate a query using the SET, and WHERE keywords only,

What I have seen is situations where things were made horribly complicated to get around protections for which there was no need, and to try to guard the consistency of data structures that were horribly over-complicated and un-normalized.

Have you ever: Been disappointed, surprised or hurt by a library etc. that had a bug that could have been fixed with inheritance and few lines of code, but due to private / final methods and classes were forced to wait for an official patch that might never come? I have. Wanted to use a library for a slightly different use case than was imagined by the authors but were unable to do so because of private / final methods and classes? I have.

Developers are faced with two realistic choices. First, they can give up, and work around the API issue (this happens more often than we would like to admit).

You can workaround this with material.translations.with_deleted.where(locale: I18n.locale).first.title But this is quite ugly.

Procs can't accept blocks as implicit arguments (the format you're trying). A proc can receive other proc objects as arguments, either explicitly, or using & arguments. Example: a = Proc.new do |&block| block.call end a.call() {puts "hi"}

The thing is Chrome doesn't provide details about such resources.

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!

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.

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.

If you're nested inside several blocks and can't use next, rather extract the contents of the transaction into its own method and use return there.

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?

Note that one extra type that is accepted by convention is the Boolean type, which represents both the TrueClass and FalseClass types.

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.

what fixed my issue was: remove the node-sass from package.json npm install install it again in latest version via npm install --save-dev node-sass if you find this helpful, I assume you just need to upgrade your node-sass for the latest version because it uses node-gyp as a lower version.

var a = document.createElement("a"); a.href = blob; a.target = "_blank"; setTimeout(function() { click(a); });

I ended up using a really poor hack, in my package.json, scripts: { ... "prebundle": "openapi bundle -o src/openapi.preprocessed.json spec/openapi.yaml --force --config .redocly.pre-processor.yaml 2>/dev/null && echo 'warning: errors from pre-processing step have been supressed'", "bundle": "openapi bundle -o src/openapi.json src/openapi.preprocessed.json ... }

There are ways to create aspect-ratio sized boxes in HTML/CSS today. None of the options are particularly elegant because they rely on the “hack” of setting a zero height and pushing the boxes height with padding. Wouldn’t it be nicer to have a platform feature to help us here?

I realize this isn't an ideal solution - but seems to be the truth to the issue. The only relevant solution I could muster is actually a hack, create a script that executes an infinite while loop that just replaces the Primary Selection with a null value.

If this proposal is fully implemented, we will end up with this garbage everywhere.

// Prevent errors crashing Node.js, see: // https://github.com/nodejs/node/issues/20392 this.promise.catch(() => {})

Yep, we experimented with this, but what we found is that you loose most of Svelte's niceness like slots, and instead you'll pass around deeply nested objects.

If you need to pass multiple arguments to an action, combine them into a single object, as in use:longpress={{duration, spiciness}}

while with server/externalFetch there is no direct way to pass cookie headers from the original request to the external one

Right now I am working around this issue by having an internal [...api].js, then call fetch for that endpoint (which automatically passes on cookies) and from there hit the actual external endpoint. It works, there is no risk of leaking anything, but imo shouldn't be necessary.

I am currently circumventing this issue by using getSession to have access to the cookies/headers in the load method

Using min-width to set the width of the iFrame, works around an issue in iOS that can prevent the iFrame from sizing correctly.

With JavaScript, you can actually calculate the width of the scrollbar and whether it’s visible by comparing two properties—window.innerWidth and document.body.clientWidth. If these are equal, the scrollbar isn’t visible. If these are different, we can subtract the body width from the window width to get the width of the scrollbar:const scrollbarWidth = window.innerWidth - document.body.clientWidthWe’ll want to perform this both on page load and on resize, in case someone resizes the window vertically and changes the overflow. Then, once we have the scrollbar width, we can assign it as a CSS variable:document.body.setProperty("--scrollbarWidth", `${scrollbarWidth}px`)

You can add event modifiers with the on:click$preventDefault$capture={handler} syntax. If you use Svelte's native on:click|preventDefault={handler} syntax, it will not compile. You have to use "$" instead of "|". (The extra S inside the | stands for SMUI.)

direnv is not loading the .envrc into the current shell. It’s creating a new bash sub-process to load the stdlib, direnvrc and .envrc, and only exports the environment diff back to the original shell. This allows direnv to record the environment changes accurately and also work with all sorts of shells. It also means that aliases and functions are not exportable right now.

I think that it's nonsense not to have a method that just gives -1 or +1. Even BASIC has such a function SGN(n). Why should we have to deal with Strings when it's numbers we want to work with. But's that's just MHO.

fetch: fetcher

First, no joypad support. It's not a big deal because you can still use big picture emulation or joy2key

Too new to comment on the specific answer

After some searching i found a stack overflow problem that didn't fix my issue but anyhow… I simply used a little ruby and the capybara library to find the field myself with some case insensitive regex and the ruby detect method

For now, you will need to give the second root a different named route: authenticated :user do root to: "users#index", as: :authenticated_root end unauthenticated do root to: "main#index" end

If I were to sum up why in one sentence, it's because I don't miss useEffect. I understand why it exists, I understand the approach React takes, and there are benefits of its approach. But writing complex React components feels more like admin; a constant worry that I'll miss a dependency in my useEffect call and end up crashing my browser session. With Svelte I don't have that lingering feeling, and that's what I've come to enjoy.

One gripe I've had with this approach is that you lose the visual cues that you're passing children into the Box component; they now aren't nested within the Box when you render them like we're used to in HTML; it's now up to you to read the props and spot which ones are being used to provide children.

Here's where I start to have a preference for Svelte; the two are very similar but once I got used to Svelte I found that React felt like jumping through hoops. You can't create a worker instance, it has to go in a useRef, and then you can't easily pull code out into a function without then requiring useCallback so it can be a safe dependency on useEffect. With Svelte I write code that's closer to "plain" JavaScript, whereas in React more of my code is wrapped in a React primitive.

because React components are re-executed every time the component re-renders, you can easily end up with thousands of workers being created! It's essential to use useRef to avoid this problem by maintaining a reference to the worker that you've created.

If you really want this, I suggest you write a little function that extracts the executable name from the .desktop file and runs it. Add these lines to your shell's initialization file (e.g. ~/.bashrc): runDesktop () { eval "$(awk -F= '$1=="Exec"{$1=""; print}' "$1")" } Then, you can run your .desktop file with runDesktop ~/Desktop/slack.desktop

A solution is almost indicated in the question: hinder xdg-open from choosing exo-open. A brute-force approach is to copy /usr/bin/xdg-open to /usr/local/bin (/usr/local/bin is earlier in PATH unless PATH has been modified) and to patch it to use open_generic instead of exo_open (unlike the XFCE4-specific exo-open, open_generic does honor xdg mime types)

neither knows what to do with naked domain. So gnome-open http://askubuntu.com works but not gnome-open askubuntu.com. Here is a small function to make it easier to type and accept the stripped down domain name. function go { gnome-open http://$1 ; }

Works also on Linux if you install Steam for Windows on Wine.

To the consternation of some users, 3.x employed Unicode variable names such as λ, φ, τ and π for a concise representation of mathematical operations. A downside of this approach was that a SyntaxError would occur if you loaded the non-minified D3 using ISO-8859-1 instead of UTF-8. 3.x also used Unicode string literals, such as the SI-prefix µ for 1e-6. 4.0 uses only ASCII variable names and ASCII string literals (see rollup-plugin-ascii), avoiding encoding problems.

I've been able to find three alternatives ahead of the bugfix

You can use the :placeholder-shown pseudo class. Technically a placeholder is required, but you can use a space instead.

There is (currently) no CSS selector for detecting directly whether an input control has a nonempty value, so we need to do it indirectly, as described above.

:placeholder-shown is super useful for us here! It’s basically the secret selector for testing if an input currently has a value or not.

Dave Rupert has a good solution that uses an input's invalid event. Instead of using the :invalid pseudo selector, he adds a CSS class to the input when it becomes invalid. We will extend this approach by removing the CSS class when the element becomes valid again.

Validating forms has notoriously been a painful development experience. Implementing client side validation in a user friendly, developer friendly, and accessible way is hard. Before HTML5 there was no means of implementing validation natively; therefore, developers have resorted to a variety of JavaScript based solutions.

You need to create a copy of the method or the class of your callable task in order to fix this and have two identical steps.

# catch multi-char special key sequences read -sN1 -t 0.0001 k1 read -sN1 -t 0.0001 k2 read -sN1 -t 0.0001 k3 key+=${k1}${k2}${k3}

For now I've worked around this by putting all the key-value pairs into an array before passing them into the interaction, then re-building the hash inside the interaction. It works, but it requires some extra code

You can use it by allowing a hash with arbitrary keys, but that loses type-safety one that object.

Thanks, I'll continue leaning on the array workaround for my use case then.

I had to use something like this: occupancy.errors.messages.each do |column, messages| messages.each { |m| errors.add(column, m) } end

So how are we going to create a model that doesn’t have a database table behind it? There are several potential solutions including various plugins but we’re going to use the method described in an entry on the Code Tunes blog. This shows a techinque that involves overriding a couple of methods in an ActiveRecord model and then manually defining the columns in the model file rather than in the database table. In our Recommendation model we’ll add in the two overridden methods and then use the column class method to define the columns in a similar way to how they’re defined in a migration file.

With the introduction of CPUs which ran faster than the original 4.77 MHz Intel 8088 used in the IBM Personal Computer, programs which relied on the CPU's frequency for timing were executing faster than intended. Games in particular were often rendered unplayable. To provide some compatibility, the "turbo" button was added. Engaging turbo mode slows the system down to a state compatible with original 8086/8088 chips.

There is nothing wrong with accepts_nested_attributes_for. This is what you should use in your typical case. My post describes a non-typical case. ContactListForm is not an ActiveRecord object, it is an object that includes ActiveModel::Model, which does not support accepts_nested_attributes_for.

A.joins(:b) .where( A.arel_table[:something_a].eq('xxx').or(B.arel_table[:something_b].eq('yyy')) )

If you need your grid to utilize a gap between columns / rows, you won't be able to use the gap property when using this method. You'd instead need to resort to some negative margin manipulation to handle the extra gap space.

I hope we see new CSS capabilities arise that allow this sort of effect without the need for trickery.

Since CSS doesn’t (yet) offer a way to style grid cells, areas, or tracks directly, we have to stretch elements over the parts we want to style independently from the elements that contain content.

proposes adding a grid-cell pseudo so you can add (responsive) decorative elements to grids without having to add empty elements to your page.

Change any of the <option> by double clicking on the number.

You can use Chromium from the Debian buster repository.

You can use Chromium from the Debian buster repository. For example, if your Ubuntu release is eoan (19.10):

It won't work if $HOME is not under /home. Really. Not even if you softlink. You need a bind mount

Why did I put the kdb in the snap file system? Because the app is sandboxed, so I had no choice.

I think this is very important feature to implement. Because for now we need to wrap target components by useless wrapper nodes.

// read-only, but visible to consumers via bind:start export let start = 0;

export const start = 0

export let start = 0

Can't find the Svelte way of doing this, setTimeout helps now, but this is not a good way working with a framework I think.

JSONP is really a simply trick to overcome XMLHttpRequest same domain policy. (As you know one cannot send AJAX (XMLHttpRequest) request to a different domain.) So - instead of using XMLHttpRequest we have to use script HTMLl tags, the ones you usually use to load JS files, in order for JS to get data from another domain. Sounds weird?

Yarn only runs the postinstall hook after yarn and yarn add, but not after yarn remove. The postinstall-postinstall package is used to make sure your postinstall hook gets executed even after a yarn remove.

It seems being able to bind:this={slotEl} directly on a slot element is a popular request. I'll add my +1 as adding div wrappers just to get dom references gets old really fast.

This creates an options object with a getter function for the passive property; the getter sets a flag, passiveSupported, to true if it gets called. That means that if the browser checks the value of the passive property on the options object, passiveSupported will be set to true; otherwise, it will remain false. We then call addEventListener() to set up a fake event handler, specifying those options, so that the options will be checked if the browser recognizes an object as the third parameter.

This pattern can be neater syntactically because declaring a variable in a try block with let scopes the variable to the try block.

If I use import { createEventDispatcher } from 'svelte/internal'; instead of import { createEventDispatcher } from 'svelte'; then it seems to work because it's loading from the same module.

So handling the interop upfront will avoid users writing invalid ES6 and make sure that they write ES6 that loads CommonJS in the right way.

Not being cancelable makes validating dialog content impossible - eg a login dialog or anything that takes user input. Of course, it's easy enough to get around - but I think this should be a requirement of a dialog.

function fail { rm -f ${tmp}* exit 1 } module load bedops || fail

set -e
{ echo 'false'; false; } && { echo 'true'; true; }
echo "Got to next line"

set -e
{ echo 'false'; false; } && { echo 'true'; true; } || exit $?
echo "Got to next line"

# Run once, hold otherwise if [ -f "already_ran" ]; then echo "Already ran the Entrypoint once. Holding indefinitely for debugging." cat fi touch already_ran

Edit this file (corresponding to your stopped container): vi /var/lib/docker/containers/923...4f6/config.json Change the "Path" parameter to point at your new command, e.g. /bin/bash. You may also set the "Args" parameter to pass arguments to the command. Restart the docker service (note this will stop all running containers):

{#key} was introduced in Svelte v3.28, before that you needed to use a keyed {#each} block with only one item When the key changes, svelte removes the component and adds a new one, therefor triggering the transition.

Thanks so much for the reply! Due to space limitations for comments, I have appended my reply to my original question. Thanks again! (P.S. I can't up-vote your reply until my rep hits 15... Sorry about that.)

...Then I just make sure that all my $: reactive statements also check whether the values are initialized or not. It's hacky, but it avoids the double render.

I don't love that you have to re-assign a object/array variable to get Svelte to notice it changed

It won't work in all use cases, but it's better than the div soup.

I run into this on almost every project and end up doing this as a workaround: :global([slot="content"]) This allows me to style that extra div in the component that contains the slots but it would be super nice to have <MyComponent slot="content"/> and eliminate that extra div

If this is getting implemented, I think I'll love to see both implemented. I can see a lot of use cases where I would like to encapsulate the component with additional wrappers and in another scenarios I would like to just use the component. Now i work around this using empty div but then at times it breaks the structure because of the div element and I'll have to add more class utilities to make it work. This will be a great addition for Svelte.

I also tried to use <!-- svelte-ignore unused-export-let --> before the script tag but still no chance.

You can only adopt a workaround, which can be one of

By using deploy keys, you don’t have to set up a fake user account.

I use a mutator and use it's changeValue function to 'change' the value of the relevant field (I supply the same value). This in turn notifies all relevant parties of the change to the form's state, and a validation is triggered.

Use the same value that was submitted, which ensures that a 'change' is triggered even though the value itself doesn't change. Therefore, the same value gets validated again.

  mutateValue([name], state, { changeValue }) {
    // change the value to the same value, thus
    // triggering a revalidation of the same value
    changeValue(state, name, value => value);
  }

But also, if you do want to use separate functions and have your dependencies still counted, you can make all of the relevant dependencies be arguments to those functions, so the compiler can see them in the reactive block.

if you make a shallow copy, it works

this is a common Svelte idiom for manually invalidating something that might have been mutated without there being a visible = sign somewhere
