I can confirm that this is still actual for Rails 7 - jpEg converts to jpg and your production fails.

Ain't it possible that every message I send or forward will just be replaced to the outbox and will be send by Thunderbird in the background ? I really hate it that every message sends itself away, running on top of all other windows, and it makes me wait till it has been sent from reading my other messages...

Personally I don’t find necessary to see the whole progress of how a mail is sent step-by-step, I just want to send the e-mail. Can’t understand why they are showing me all these but anyway

The input format of the xargs command doesn't match what any other command produces.

The input format of the xargs command doesn't match what any other command produces. Yes, it's bizarre. With -I, xargs ignores indentation, which is why the file names with initial spaces are mangled. Do not use xargs except with the -0 option or when you know your input doesn't contain characters that would confuse it.

Why would a text message service require Location (GPS) permissions? Anyway I enabled this Location permission for testing. Heureka!!! Suddenly I was able to send text messages again to all the contacts which previously didn't work. The "Not sent, tap to try again" error was gone.

i commissioned some original polling for my book from abacus research and i found some very hopeful stuff and you know the public gets the emergency and incidentally i've tried to recast 00:12:46 some of the the extreme weather events we've experienced as attacks on our soil let's think about them that way yeah um and they're ready for bold action actually the public is ahead of our politics in terms of that i was surprised to see 00:12:58 that you even mentioned in alberta the numbers are much higher than you so you mentioned quebec before so the the opinion polling nationally ranges from a high in quebec in terms of their readiness fraction right to a low in alberta but even in alberta 00:13:12 the level of support is remarkably high

The first example needs a custom inflection rule: loader.inflector.inflect("max_retries" => "MAX_RETRIES") Otherwise, Zeitwerk would expect the file to define MaxRetries.

Note that the mere presence of this header causes premailer to be skipped, i.e., even setting skip_premailer: false will cause premailer to be skipped. The reason for that is that the skip_premailer is a simple header and the value is transformed into a string, causing 'false' to become truthy.

It seems that the method is a direct equivalent of a.fdiv(b).ceil, and as such, annoyingly unnecessary, but fdiv, due to floating point imprecision, might produce surprising results in edge cases

I agree with this statement so much. We should absolutely be failing hard rather than forcing people to debug thread safety issues at runtime. I can't think of anything more infuriating than debugging an issue that happens "sometimes".

The problem is that in the case where an app is multi-threaded, and we don't switch off autoload, the case would be that it probably won't blow up, but random stuff will mysteriously sometimes fail in weird ways. So ask yourself this, what would you rather want, option 1) where you can get an exception at runtime, or option 2) where you get random, unpredictable, weird, hard to explain, difficult to debug bugs at runtime. Personally, I'm going to choose option 1. The downside of thread-safety issues is so much worse than the downside of the possibility of an exception. The way you're handling it makes it sound as though thread-safety is not important, as though Rails is still optimizing for the single-threaded case. That seems like a huge step back.

It may seem like Testing is some sort of beta, unstable version but that’s not entirely true. Debian Testing is the next Debian stable version. The actual development branch is the Debian Unstable (also known as Sid). Debian Testing lies somewhere in between the unstable and stable branch where it gets the new features before the stable release.

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.

Been disappointed, surprised or hurt by a library etc. that was overly permissive in it's extensibility? I have not.

No, in Python "[ [] foo [] boo [][]] ".strip(" []") returns "foo [] boo".

I was very surprised to discover that Finder has no native SFTP integration. As an everyday Gnome user, it is unbelievable to me, how this can even be

dependent: :destroy associations are deleted when performing soft-destroys requiring any dependent records to also be acts_as_paranoid to avoid losing data.

I've worked with and have helped maintain paranoia for a while. I'm convinced it does the wrong thing for most cases. Paranoia and acts_as_paranoid both attempt to emulate deletes by setting a column and adding a default scope on the model. This requires some ActiveRecord hackery, and leads to some surprising and awkward behaviour.

paranoia has some surprising behaviour (like overriding ActiveRecord's delete and destroy)

This still seems like a bug, as the expected behavior doesn't occur and it's difficult (for someone unfamiliar with the inner workings of ActionMailer) to debug. I spent a good half an hour figuring out the work around, so I'm trying to prevent others from experiencing the same thing.

However after doing a bit of testing I see that this character is not used to represent missing glyphs on either my Windows 7 computer or the Android phone I've tested with (Motorola Atrix).

I just spent a day dismantling a model, trying to find the cause of the silent rollback - taking out every association, every validation, every callback, whittling down all the code in the transaction, only to finally discover that it was return true that was the cause of it all. Or yes, an exception!

I think I had expected that existing rails developers would discover this problem in existing code through the deprecation warning to avoid a nasty surprise. I'm worried about my future kids learning Rails and writing perfectly looking Ruby code just to learn the hard way that return is sometimes a nono! Jokes aside, I think that no one expected that the deprecation will turn into silent rollbacks. This is a very controversial change, pretty much everyone taking part in the discussion on the deprecation PR raised some concerns about the potential consequences of this change. The only thing that was making it easier to swallow was the promise of making it clear to the user by throwing an exception after the rollback.

Note: For keyword parameters, use @param, not @option.

then two different listeners/renderers switching magically between each other based on the header being present or not, without the end user being informed or clear about this

This is actually the most correct answer, because it explains why people (like me) are suddenly seeing this warning after nearly a decade of using git. However,it would be useful if some guidance were given on the options offered. for example, pointing out that setting pull.ff to "only" doesn't prevent you doing a "pull --rebase" to override it.

This was a surprise to me, since we generally authenticate the record quite well, but then go on to do something like record.file.url in our view, generating a URL that is permanent and unauthenticated.

Explicitly defining the dependency in the reactive declarations

inputValue = updateInputValue(value);

maybe this just comes down to general footguns with reactivity, and being aware of them as a developer.

if you put the reactive statement $: validate(inputValue); after the function updateInputValue declaration, it's working as expected:

So now the question is, why does Session, an interface, not get implicit index signatures while SessionType, an identically-structured typealias, *does*? Surely, you might again think, the compiler does not simply deny implicit index signatures tointerface` types? Surprisingly enough, this is exactly what happens. See microsoft/TypeScript#15300, specifically this comment: Just to fill people in, this behavior is currently by design. Because interfaces can be augmented by additional declarations but type aliases can't, it's "safer" (heavy quotes on that one) to infer an implicit index signature for type aliases than for interfaces. But we'll consider doing it for interfaces as well if that seems to make sense And there you go. You cannot use a Session in place of a WithAdditionalParams<Session> because it's possible that someone might merge properties that conflict with the index signature at some later date. Whether or not that is a compelling reason is up for rather vigorous debate, as you can see if you read through microsoft/TypeScript#15300.

therefore in practice it's a bit academic to worry about which lines inside that block the compiler should be happy or unhappy about. From falsehood, anythihng follows. So the compiler is free to say "if the impossible happens, then X is an error" or "if the impossible happens, then X is not an error". Both are valid (although one might be more or less surprising to developers).

I don't like that I can't really use head? to know it's a HEAD request, but I (think I) understand the reasoning

Hello, maksimets: code blocks using triple backticks (```) don't work on all versions of Reddit!Some users see this / this instead.

.isnumeric() matches 430 Unicode codepoints in the BMP that float() won't accept, and there are codepoints that .isdigit() returns true for that are also not convertible.

the lack of touchscreen support is an odd omission considering both games previously appeared on 3DS and Wii U,

Every player I've introduced this game to has looked at me as if to say, "We must be doing something wrong." But no, that game is designed that way.

It's strange to me that the text returned is in all caps (how it's styled after CSS), but the matcher is actually testing against the text in the unstyled HTML. I spent a while digging through the source code and I still can't figure out why this works.

If you change a form value to '', Final Form will set the value in its state to undefined. This can be counterintutive, because '' !== undefined in javascript.

Athena is still in production use at MIT. It works as software (currently a set of Debian packages)[2] that makes a machine a thin client, that will download educational applications from the MIT servers on demand

I don't get it. Can someone please explain? I've upgraded my Rails project to Sprockets 4, just to get source maps in production. Instead I got sourcemaps in development?

So, despite your code is type safe it is not safe to be used.

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.

Another problem I found with Reform is the synchronisation with models. The object you passed in argument to reform does not have the same value than the form.

@conference_form.submit(conference_params)

    @conference_form = ConferenceForm.new(conference)
    @conference_form.submit(conference_params)

    if @conference_form.save

100vw is 100% of the viewport width not accounting for scrollbars (unless the root element has anything other than overflow: auto set, but auto is the default value). Thus, when the page content overflows the viewport vertically, the browser renders the vertical scroll bar, which reduces the visible viewport area by a few pixels. But the 100vw value doesn't update to account for this, so the selected div retains the same width as before the vertical scrollbar appeared. This results in the horizontal scroll bar rendering.

Now, however, you set width:100vw and that is going to be (in this case) 100% wide (viewport wide) + the vertical scrollbar width. That’s too wide. That induces the HORIZONTAL scrollbar.

This is funny because it’s unexpected. Cache invalidation sounds like a hard thing, while naming sounds more straightforward. The joke works because it violates our expectation that hard things should be technical. It’s also funny because it’s true.

In 2025 we plan to

It seems like this should be one of the easiest things to understand in CSS. If you want a block-level element to fill any remaining space inside of its parent, then it’s simple — just add width: 100% in your CSS declaration for that element, and your problem is solved. Not so fast. It’s not quite that easy. I’m sure CSS developers of all skill levels have attempted something similar to what I’ve just described, with bizarre results ultimately leading to head scratching and shruggingly resorting to experimenting with absolute widths until we find just the right fit. This is just one of those things in CSS that seems easy to understand (and really, it should be), but it’s sometimes not — because of the way that percentages work in CSS.

min-width: 0;

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

In my opinion, this single-tab Refresh behavior strongly violates the principle of least surprise, and it doesn’t help us to maintain code consistency or data consistency.

What I think is happening is that instantiating the component is immediately running the $: reactive code, which dispatches the event synchronously, before the parent component attaches the listener.

But now Chromium is no more available as deb, so what to expect ?

Note that when using sass (Dart Sass), synchronous compilation is twice as fast as asynchronous compilation by default, due to the overhead of asynchronous callbacks.

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

This mirrors how classes already work and avoids the issues with introducing an unexpected DOM node.

I came up with this solution by piecing together man pages and random google result. I was surprised at how many incomplete and inaccurate answers were out there. What may have been more surprising was the complete lack of a full intact solution.

I debugged docker-compose and docker-py and figured out that you should either use environment variables or options in command. You should not mix these . If you even specify --tls in command then you will have to specify all the options as the TLSConfig object, as now TLSConfig object is created completely from the command options and operide the TFSConfig object created from the environment variable.

docker --tlsverify ps executes just fine, while docker-compose --tlsverify up -d --force-recreate gives me an error: SSL error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

I only have one set of certs. And I can't see how they can be different because docker commands work using the endpoint. It's just the docker-compose command that fails

docker-compose command you can not mix environment variable and command option. You can specify setting in env variable and then just use docker-compose ps. The connection will be secured with TLS protocol if DOCKER_TLS_VERIFY variable is set.

You dont need to pass --tls or --tlsverify option in the docker-config path as the task already sets DOCKER_TSL_VERIFY environment varaible. I debugged docker-compose and docker-py library and verified that if you pass any flag --tls or --tlsverify flag it tries to create tslConfig object out of options and not from environment

Library author here. I'm always fascinated by new ways people can invalidate my assumptions. I mean that in a sincerely positive way, as it results in learning.

When using a method in a top-level object to modify its state, such object isn't updated either.

I too have been confused by behavior like this. Perhaps a clearly defined way to isolate atomic units with synchronous reactivity would help those of us still working through the idiosyncrasies of reactivity.

For performance reasons, $: reactive blocks are batched up and run in the next microtask. This is the expected behavior. This is one of the things that we should talk about when we figure out how and where we want to have a section in the docs that goes into more details about reactivity. If you want something that updates synchronously and depends on another value, you can use a derived store:

I expected that the param being passed by reference to have the same reactivity of the variable being created in the script tag.

One would expect the display to be updated, but it is not... WHY is it updated the 2nd time you enter something? What is different?

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.

yup.object.default({ number: 5 }); // object will be cloned every time a default is needed yup.object.default(() => ({ number: 5 })); // this is cheaper

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.
