You can imagine how big of a surprise was finding out that model/character being a child of model/node causes an error when we import model/position.

To fix our Svelte version you might think we could use beforeUpdate or afterUpdate, but these lifecycle functions are related to the DOM being updated, not to prop updates. We only want to rerun our fetching when the album prop is changed.

If the user now clicks Back again, the URL bar will display https://www.mozilla.org/foo.html, and totally bypass bar.html.

There'll be no more warnings. But if you open bundle.js, you'll see something shocking: it contains the entirety of React and React DOM. That's 7000 LoC!

Basically, the idea is that a train tried to start with the caboose brakes stuck on. After releasing the caboose, the train still could not start. The problem was that when the train attempted to start with the caboose brake on, it stretched all the inter-car couplings so that the whole train was just like one big car. At this point, the friction from the engine train wheels was not enough to get the whole thing going. Instead, you need to just get one car moving at a time - this is why there is space between the couplings.

Most simple example: <script> import ChildComponent from './Child.svelte'; </script> <style> .class-to-add { background-color: tomato; } </style> <ChildComponent class="class-to-add" /> ...compiles to CSS without the class-to-add declaration, as svelte currently does not recognize the class name as being used. I'd expect class-to-add is bundled with all nested style declarations class-to-add is passed to ChildComponent as class-to-add svelte-HASH This looks like a bug / missing feature to me.

It's fashionable to dislike CSS. There are lots of reasons why that's the case, but it boils down to this: CSS is unpredictable. If you've never had the experience of tweaking a style rule and accidentally breaking some layout that you thought was completely unrelated — usually when you're trying to ship — then you're either new at this or you're a much better programmer than the rest of us.

Now I know what you're thinking, "this is an atrocity, what a horrible mess!" and you're right, it's kind of ugly. In fact it's just about impossible to think this is a good idea the first time you see it — you have to actually try it.

I'm just trying out the "Reply to comment" button here. Well, it seems like it doesn't quote the text... that's really the feature I'd like to exposed. When responding to a large message (email or otherwise), I like to quote various parts and respond in line.

Nevertheless, this is quite confusing and has lead to a recently reported issue on the Webpacker GitHub repository.

The inherent stealth conversion into Sets is not a good idea in my book.

To me the difference between [1,1,2,2,3,3] and [1,2,3] is not []

Code doing surprising and slightly nonsensical things... I'm weary now. And that's with ruby being more consistent than most!

One may expect Array#- to behave like mathematical subtraction or difference when it doesn't. One could be forgiven to expect the following behavior: [1,1,2,2,3,3,4,4] - [1,2,3,4] => [1,2,3,4]

I'll freely admit I was surprised by this behavior myself since I needed to obtain an Array with only one instance of each item in the argument array removed.

However, a ActiveRecord::Rollback within the nested transaction will be caught by the block of the nested transaction, but will be ignored by the outer transaction, and not cause a roll back! To avoid this unexpected behaviour, you have to explicitly tell rails for each transaction to indeed use proper nesting: CopyActiveRecord::Base.transaction(joinable: false, requires_new: true) do # inner code end This is a safer default for working with custom transactions.

transaction calls can be nested. By default, this makes all database statements in the nested transaction block become part of the parent transaction. For example, the following behavior may be surprising: User.transaction do User.create(username: 'Kotori') User.transaction do User.create(username: 'Nemu') raise ActiveRecord::Rollback end end creates both “Kotori” and “Nemu”. Reason is the ActiveRecord::Rollback exception in the nested block does not issue a ROLLBACK. Since these exceptions are captured in transaction blocks, the parent block does not see it and the real transaction is committed.

You might not care today, but your approach doesn’t allow you to have multiple spaces (Philippines   6014), leading spaces, trailing spaces, or tabs.

Chances are that you think that you can compile a Ruby binary on a certain OS, and that users using that same OS can use your Ruby binary. Not quite. Not even when they run the same OS version as you do.

If we find that GitLab doesn't work as people expect, the documentation should be updated so this is no longer a surprise. This applies whether we classify it as a feature request or a bug.

Unexpected features “Unexpected” features are those that are unrelated to the add-on’s primary function, and are not likely from the add-on name or description to be expected by a user installing that add-on. Should an add-on include any unexpected feature that falls into one of the following categories: Potentially compromises user privacy or security (like sending data to third parties) Changes default settings like the new tab page, homepage or search engine Makes unexpected changes to the browser or web content Includes features or functionality not related to the add-on’s core function(s) Then the “unexpected” feature(s) must adhere to all of the following requirements: The add-on description must clearly state what changes the add-on makes. All changes must be “opt-in”, meaning the user has to take non-default action to enact the change. Changes that prompt the user via the permissions system don’t require an additional opt-in. The opt-in interface must clearly state the name of the add-on requesting the change.

Capybara and Webrat use some of the same method names which leads to runtime collisions that reveal themselves in confusing ways.

To be just a bit polemic, your first instinct was not to do that. And you probably wouldn't think of that in your unit tests either (the holy grail of dynamic langs). So someday it would blow up at runtime, and THEN you'd add that safeguard.

As many would guess: ... catch StandardError => e raise $! ... raises the same error referenced by $!, the same as simply calling: ... catch StandardError => e raise ... but probably not for the reasons one might think. In this case, the call to raise is NOT just raising the object in $!...it raises the result of $!.exception(nil), which in this case happens to be $!.

Legitimate Interest may be used for marketing purposes as long as it has a minimal impact on a data subject’s privacy and it is likely the data subject will not object to the processing or be surprised by it.

The .ignore file , from what I can tell, needs to exist in the directory you're targeting for it to be recognized, not the current directory. If you're searching in .src, the file would need to be there for it to work.
