Is there any way to force an exhaustive check of all enum values when the switch branches call methods with void return type? It's quite ugly to hard-code a yield just to coax the compiler to demand exhaustiveness.

This is my current pattern (the handle methods have void return type)

I suspect there is some way to use an element’s transformation matrix to calculate its coordinates after being transformed, but I don’t know how to do so.

An example diagram explains this best:

I’m afraid I didn’t take the math route into programming. I can sort-of follow the surface-level details of what a transformation matrix is doing, but my understanding is sort of like being able to read music one note at a time, and only very slowly; I don’t really understand the tune at a higher level, so I don’t really understand the sound of a complete musical phrase—let alone the melody.

Similarly, I don’t understand how transformation matrices work. I have tried searching for explanations to grok transformation matrices, but everything I find is loaded with more math jargon I don’t understand. I just know that they work sort of like a function, and that they are incredibly flexible tools, but that’s it.

Of all the methods available to SVGMatrix (supposedly deprecated in favor of DOMMatrix, but Firefox Dev. ed. is still using SVGMatrix), I have no idea whether .inverse() or .multiply() is what I want, and no idea how to coax a simple set of x and y coordinates out of that matrix.

Note:

• I am not interested in translating screen-to-SVG coordinates here.
• I am only concerned with SVG (user-space) coordinates.

Due to working from home, I need a way to monitor a remote neo4j instance - preferably through a web browser instance.

In the past (eg in 3.0) it could be easily achieved by modifying a single config line.

Unfortunately, with the version 4.2 this is no more the case - the line is not there anymore and attempts to coax the new connectors configs to work in the same way, aka changing:

I'm using Laravel 8.x and trying to get the built-in login/registration code to work properly on a new project. I don't have much prior experience with Laravel or its authentication code but if I recall correctly, when I register, I'm supposed to get a confirmation email that must be replied to for the registration to be fully successful. I'm not getting that confirmation email.

The users table has a row in it for both of the two IDs I've registered - both emails belonging to me - but neither email address has received a confirmation email after a substantial wait. I've also checked my junk/spam folders and verified that the confirmation email didn't go there. The rows in the users table have nulls in the "email_verified_at" and "remember_token" columns so I know that the registration did something, it just didn't send the confirmation emails. I haven't touched any of the modules involved in registration; in fact, I recreated them from scratch before attempting to register anything.

What do I have to do to coax Laravel to send the confirmation emails?

how can I add key-value pairs to a dictionary automatically? for example I have a very long file of one word in Greek, and the translation in English (these are separated by a ";"): this is repeated for many lines and I would like to put each line (formed by "Greek;translation") in the dictionary. I show you an example:

I have implemented the web speech api (webkitSpeechRecognition) in an application and it works as expected when running locally (localhost). Once deployed to a shared test server it throws the "not-allowed" error as soon as it starts to listen. I assume this means there is a security violation that prevents it from accepting input. However the site is HTTPS and fully secure (valid cert, no unsecure mixed content). It's not operating from within an Iframe.

I'm never prompted for permission to use the microphone. I have already tried setting microphone access within Chrome to "allow" for the site. I'm using the latest Chrome browser on Windows 10.

Does anyone know how to coax more detailed error info from this API? Has anyone come across similar problems in trying to implement this API?

thanks!

I am struggling to find a way to read this json blob into tuples for each record, the author of the database wrote the data in as json blob. When I try to pull the data out of the db however I cannot find any examples on how to decode this blob data into tuples. What I shared below is the actual dump from the sqlite database which is structured as blob. I need to read that into tuples so I can use the individual values .

I'm in the process of setting up my flutter ios app for a cloud build (AppCenter) and I am running into an issue with my xcode config(?).

When building locally, I used to set a linker flag in Xcode to prevent common “double-quoted include” errors. (A known cocoapod issue, apparently...) Ticking the flag in the XCode GUI set CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER = NO in ./ios/Runner.xcodeproj/project.pbxproj and ios/Pods/Pods.xcodeproj/project.pbxproj and allowed the build to finish with lots of warnings but no errors.

I committed both pbxproject files (and even the entire ios/Pods dir) and thought this would save my flag settings, but I had to realize that a build from a fresh checkout regenerates the Pods/ config with a default set to true.

How can I coax the flutter ios config into remembering that flag setting across clean builds?

P.S.: I should mention that I am running a slightly older version of xcode (11.3.1)

I've been working on a script that retrieves favicons from sites, which is now mostly working, but I've run into a huge roadblock. When I call on the ImageMagick module in Perl, it doesn't seem to know what to do with the venerable favicon.ico file (everything is working great when a site has a non-ICO favicon). I can find lots of information on converting to ICO to create a favicon, but not much about converting from ICO.

After I retrieve the favicon, I use PerlMagick's ping function to figure out what kind of file I'm dealing with (so I'm not dependent on the icon's server to report accurately):
