You can use both toLowerCase() and toUpperCase() before comparing the correct answer and the input from the user,

change this, interrogate === arr[i][1]

as, interrogate.toLowerCase() === arr[i][1].toLowerCase()

Most of the time, when I was testing on a MacBook Pro running Big Sur 11.6.3, the commands run to completion. I'm using a program tester to run the server and then the client — the advantage of the program is that I can report the exit statuses of the client and server programs accurately. I've been using increasingly elaborate test rigs to capture the information.

Every so often, I seem to get the server dying immediately. I believe that's a timing issue due to the o/s scheduler. The launch code runs the client after launching the server, but it so happens that the system scheduler runs the client before the server has set up its signal handler and so the server is killed by the client's initial signal.

I modified both the client and server programs to include alarm(15); so that the processes time out after 15 seconds. Most of the time, it takes the pair less than a second to complete. On those occasions when things fail, I get the server exiting with status 0x001E (which indicates it died from a SIGUSR1 signal) and on the same runs, the client exits 15 seconds later with status 0x000E (which indicates it died from a SIGALRM signal). The log files contain no 'received" messages.

First you'll have to set the ParallaxComponent to not move the component itself with the camera (this was a bug from our side, it will be default in the next version).

You do this by setting positionType = PositionType.viewport; in the component (or override that field).

Now you can connect the camera.position to the baseVelocity of your parallax, something like this for example:

After some research, I came to know that all these kill commands are just killing the process whereas in this case, we need to stop the process.

Could NFT be created from the same image or copy of this image?

Can someone download the image and create an NFT from it?

Yes to both questions. It is technically possible to create multiple NFTs that all represent the same image. They can be placed in the same collection, as well as across multiple collections.

As NFTs basically contain links to this image, it's not possible to prevent someone from creating a link to a public resource, i.e. from creating another NFT representing the same image.

I mean, isn't it part of the idea that this is original content by me and I have the copyrights for it?

The ERC-721 standard mostly defines just the technical specifications. But it doesn't really cover the licensing, ownership/authorship of the underlying resource, and other non-technical topics.

An NFT only proves ownership of the token - not copyrights of the image. Also, it proves ownership by an address - not by a person. Because there can be zero to multiple people holding a private key to the same address (holding the NFT representing the image).

Container environment is not related here.

It seems like libc (where malloc implementation resides) on your system is compiled without frame pointers. So the standard stack walking mechanism in the kernel is unable to find a parent of malloc frame.

I've recently implemented an alternative stack walking algorithm that relies on DWARF unwinding information. New version has not been yet released, but you may try to build it from sources. Or, for your convenience, I prepared the new build here: async-profiler-2.6-dwarf-linux-x64.tar.gz

Then add --cstack dwarf option, and all malloc stack traces should be in place.

All Flame games are added to the GameWidget, and this GameWidget can be put anywhere inside of your Flutter widget tree.

Do note that if you don't want your game to be reset when the widget tree is rebuilt, keep a reference to is outside of the GameWidget.

JDK Flight Recorder (JFR) can measure allocation rate per allocation site (method), but it's sample based, so it trades accuracy for overhead. You need a few thousands samples. The overhead of recording the stack trace (or method) for every allocation is enormous and would bring the application to a halt.

JDK 16 introduced a new event (ObjectAllocationSample) that caps the number of events per second. You should be able to see it in JMC. If not, here is a small program that will give you a histogram of allocation per method.

You are correct that Transform2D does not allow these kinds of "additional transforms on top" -- mostly because the transform matrix gets recalculated whenever any underlying property changes. However, you can create a derived class, overriding the transformMatrix getter so that it applies additional transformations.

I'm not sure what's the best way for implementing isometric games in Flame, but you could try the following approach:
