stitches is a Ruby library typically used in Server, Application Framework, Ruby On Rails applications. stitches has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Create Microservices in Rails by pretty much just writing regular Rails code. This, plus much of what you get from Rails already, means you can create a microservice Rails application by just writing the same Rails code you write today. Instead of rendering web views, you render JSON (which is built into Rails).

            React & TypeScript Upload File Input Error
            Asked 2022-Mar-21 at 18:41

            I'm trying to submit a form with react & typescript but keep getting errors.

            My terminal outputs this error Type 'File | undefined' is not assignable to type 'string | number | readonly string[] | undefined' and if I try to upload a file the website crashes with this warning and error.

            Warning: A component is changing an uncontrolled input to be controlled. This is likely caused by the value changing from undefined to a defined value, which should not happen. Decide between using a controlled or uncontrolled input element for the lifetime of the component.

            Uncaught DOMException: Failed to set the 'value' property on 'HTMLInputElement': This input element accepts a filename, which may only be programmatically set to the empty string. at HTMLInputElement.set [as value]

            -- EDIT --

            So after debugging for a while I have discovered that if I just pass an empty string into the value attribute then the form submits and my image / file is processed and works fine. So the issue lyes with the setting of the value attribute which mean it's this error I need to fix! Failed to set the 'value' property on 'HTMLInputElement': This input element accepts a filename, which may only be programmatically set to the empty string. at HTMLInputElement.set [as value]

            I have the following input component



            Answered 2022-Mar-21 at 18:41

            Since the value of a file input is read-only, it can only be an uncontrolled element, which means it does not take value prop. docs

            In your custom input element, you may want to check the type before passing the value prop.



            Why does this red color fill only one frame PIL?
            Asked 2021-Nov-09 at 14:21

            Alright so I have some code that takes user input, fetches each letter's corresponding gif (a dancing letter) and stitches them together to form a word. Kind of like an animated font, basically.

            My problem is that with PIL, it occasionally fills the background of one of the letters for around 1 frame with a red color, as demonstrated here:

            How to wraparound in the 64KB code segment in a program that stitches itself to its own tail, ad infinitum?
            Asked 2021-Aug-09 at 08:59

            If the sequential execution of instructions passes offset 65535, then the 8086 will fetch the next instruction byte from offset 0 in the same code segment.

            Next .COM program uses this fact and continually stitches its entire code (32 bytes in total) to its own tail, wrapping around in the 64KB code segment. You could call this a binary quine.



            Answered 2021-Aug-09 at 08:59

            In 16-bit mode (real or protect), the IP register will wrap around 64KiB without any fault, granted that no instruction crosses the 64KiB boundary (e.g. a two bytes instruction placed at 0xffff).

            A crossing instruction will fault on an 80386+, not sure what will happen on previous models (read the next byte in the linear address space? read the next byte from 0?).

            Note that this works because the segment limit is the same as the IP register "limit".
            In 16-bit protected mode you can set a segment limit less than 64KiB, in that case, the execution will fault when reaching the end.
            In short (and figuratively), the CPU makes sure all the bytes it needs are within the segment limit and then will increment the program counter without overflow detection.

            So your program should work.

            It's probably a bit of a stretch to call it a quine because it's reading its own machine code and that's cheating (just like reading the source code file is for high-level languages).

            I haven't tested it, but a very minimal example of a program "kind of replicating" itself could be:

            Using Tasks for a lot of HTTP requests
            Asked 2021-Jul-18 at 22:43

            So I'm having some difficulties with using Tasks to handle loads of HTTP requests.

            What I'm trying to do, is to create a large image from a WMTS. For those who don't know, a WMTS is a Web Map Tile Service. So basically, you can request image tiles that are 256x256 by sending a request with the correct tileRow and tileColumn. So in this case I'm trying to construct images that contains hundreds or even thousands of these image tiles.

            To do this, I created an application that:

            • calculates which tiles it needs to request based on input.
            • creates a list that I can use to do the correct HTTP requests to the WMTS.
            • sends these requests to the server and retrieves the images.
            • stitches the images together into one large image. Which is the result that we want.

            As you may imagine, the amount of tiles grows exponentially. This doesn't really impact the CPU work, but is mostly I/O bound work. So instead of waiting for each request to return, before sending the next one, I thought it would be a good idea to use Tasks for this. Create the tasks that will handle each individual request, and when all tasks are finished, construct the large image.

            So this is the method where I already know what tiles I am going to request. Here I want to recursively send the requests with tasks until all the data is complete (eventually with a max retry mechanism).



            Answered 2021-Jul-18 at 22:43

            Yes, tasks are the way to go, but no, ContinueWith is not the way to go. This method is mostly a relic from the pre async-await era, and it's rarely useful nowadays. The same is true for the Task.Factory.StartNew: you rarely need to use this method after the introduction of the Task.Run method.

            A convenient way for creating the tasks needed to download the tile data, is the LINQ Select operator. You could use it like this:

            Selenium - Taking full-page mobile screenshots via BrowserStack
            Asked 2021-Apr-18 at 16:13

            I’ve created a tool to take full-page screenshots on a list of URLs on a number of desktop and device configs. On desktop, this all works swimmingly and I get full-page screenshots back with no issue on all browsers and OS versions.

            The problem comes when trying to do this on mobile devices, which I'm guessing is due to the pixel ratio of the devices I’m running on.

            My method takes the total height and width of the page, as well as the height and width of the viewport, and basically takes images of the viewport, scrolls where necessary, then at the end, stitches all this together into a single image.

            However, with the pixel ratio, which I’m retrieving via JavaScript, the screenshots are never captured properly and don’t scroll correctly and/or don’t capture the entirety of the page. Widthwise it’s ok, it’s always height. It's like it's calculating the scrolling incorrectly

            I’m staggered by the fact that I can’t find any posts anywhere online with people who have had the same or similar issues. So either I’m over complicating it and it’s so trivial that it’s never required a post, or this is way harder than I think and people aren’t doing it for good reason

            If anyone has any thoughts or ideas, they would be very much appreciated

            How do I transfer files from s3 to my ec2 instance whenever I add a new file to s3?
            Asked 2021-Feb-19 at 04:43

            I have a py script which is in my ec2 instance. That requires a video file as input which is in an S3 bucket. How do I automate the process where the ec2 instance starts running every time a new file is added to that bucket? I want the ec2 instance to recognize this new file and then add it to its local directory where the py script can use it and process it and create the output file. I want to then send this output file back to the bucket and store it there. I know boto3 library is used to connect s3 to ec2 , however I am unclear how to trigger this automatically and look for new files without having to manually start my instance and copy everything

            Edit: I have a python program which basically takes a video file(mp4) and then breaks it into frames and stitches it to create a bunch of small panorama images and stores it in a folder named 'Output'. Now as the program needs a video as input, in the program I refer to a particular directory where it is supposed pick the mp4 file from and read it as input. So what I now want is that, there is going to be an s3 bucket that is going to receive a video file from elsewhere. it is going to be inside a folder inside a particular bucket. I want any new mp4 file entering that bucket to be copied or sent to the input directory in my instance. Also, when this happens, I want my python program stored in that instance to be automatically executed and find this new video file in the input directory to process it and make the small panoramas and then store it in the output directory or even better, send it to an output folder in the same s3 bucket.



            Answered 2021-Feb-17 at 04:34

            There are many ways in which you could design a solution for that. They will vary depending on how often you get your videos, should it be scalable, fault tolerant, how many videos do you want to process in parallel and more. I will just provide one, on the assumption that the new videos are uploaded occasionally and no auto-scaling groups are needed for processing large number of videos at the same time.

            On the above assumption, one way could be as follows:

            1. Upload of a new video triggers a lambda function using S3 event notifications.
            2. Lambda gets the video details (e.g. s3 path) from the S3 event, submits the video details to a SQS queue and starts your instance.
            3. Your application on the instance, once started, pulls the SQS queue for details of the video file to process. This would require your application to be designed in a way that its starts a instance start, which can be done using modified user data, systemd unit files and more.

            Its a very basic solution, and as I mentioned many other ways are possible, involving auto-scaling group, scaling policies based on sqs size, ssm run commands, and more.



            geom_sf fill fails when xlim, ylim are specified using coord_sf. Looking for a workaround when trying to create an animation using the av package
            Asked 2021-Jan-04 at 16:50

            There is a known issue for ggplot2 where the geom_sf function does not always work as excepted when specifying xlim and ylim using coord_sf. This issue seems to be specific to Windows, and the current work around involves saving the plot as a .png. See GitHub link: geom_sf fill missing when xlim,ylim set in coord_sf

            The problem I am having is that I am not trying to make a static plot, but rather an animation that stitches hundreds of plots together using the av package.

            Basically, I am looking for help implementing a suitable work around, and one that does not require saving or calling individual .png files.

            Any ideas or suggestions would be great much appreciated.

            As suggested by Thomas Lin Pedersen in the github issue you're linking, the solution would be to use the png(..., type = 'cairo') device on Windows machines. If you read the documentation at ?av::av_capture_graphics(), you'll see that the ... argument can be used to pass arguments to the png() function. Hence, I propose to do exactly that:
