I have been having this problem for a couple of weeks now.

How to run CSS animation of two keyframes continuously

By Ritesh Sahu - October 31, 2020

I would like to run my animation consisting of two keyframes to mimic the motion of a closing garage door, but the animation stops after one execution. Adding animation-iteration-count: 10; just flashes the 'door', doesn't rerun the whole animation. What could be the issue? Thank you in advance! .house { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); width: 200px; height: 150px; } .house .front { position: absolute; bottom: 0; left: 50%; transform: translateX(-50%); width: 5.2em; height: 4em; border-left: 0.5em solid grey; border-right: 0.5em solid grey; } .house .front .gable { position: absolute; top: -3.5em; left: 50%; width: 0; height: 0; transform: translateX(-50%); border-left: 3.1em solid transparent; border-right: 3.1em solid transparent; border-bottom: 3.5em solid grey; } .house .front .door { position: absolute; bottom: 0; left...

Flask: detect calling view and redirect accordingly

By Ritesh Sahu - October 31, 2020

In a Flask application I've a template showing a list of short notices to the user. I've enclosed this part in a Blueprint called board . The user can click a link to accept a notice. The application records the acceptance to a database and shows the list of notices with the total number of acceptances updated. THE PROBLEM: the user can also click a notice to see a detailed view of it. He can accept the notice also in the detailed view. The application records the acceptance and shows the same detailed view updated. I want to manage this view in the same Blueprint since most of the code is in common. WHAT WORKS FINE: I've two separate endpoints for notices list acceptance and detailed view acceptance. Here's the template for the list "calling" the accept function: <p> <a class="action" href="">accept</a> </p> and the code taking care of it: @bp.route("/<int:id>/accept") @login_required...

React/JS How to get the value of last index of props.data which is an object

TestCafe EC2 Network logs

By Ritesh Sahu - October 31, 2020

We are "successfully" running our gherkin-testcafe build on ec2 headless against chromium. The final issue we are dealing with is that at a certain point in the test a CTA button is showing ...loading instead of Add to Bag, presumably because a service call that gets the status of the product, out of stock, in stock, no longer carry, etc. is failing. The tests work locally of course and we have the luxury of debugging locally opening chrome's dev env and inspecting the network calls etc. But all we can do on the ec2 is take a video and see where it fails. Is there a way to view the logs of all the calls being made by testcafe's proxy browser so we can confirm which one is failing and why? We are using. const rlogger = RequestLogger(/.*/, { logRequestHeaders: true, logResponseHeaders: true }); to log our headers but not getting very explicit reasons why calls are not working. from Recent Questions - Stack Overflow https://ift.tt/31XkYXb https://ift.tt/eA8V8J

why is drawing a bitmap on a canvas then moving it duplicating it? android, java

TestCafe loop over elements and check if class exists within Set

By Ritesh Sahu - October 31, 2020

I have a table with a column of icons. Each Icon has a class of "test" and then "test" + [some rating]. The rating could be A, B, C, XX, YY. I'd like to select the group of icons and loop over them, pop off the last class (the one with the rating) and then expect that my Set of classConsts contains the class in question. I've done a bunch of research but can only find examples of interacting with each of the elements, I'm not sure what I'm doing wrong when trying to check the classes on each instead. Any help is appreciated, thanks. The below code blows up when i call mrArray.nth saying it's not a function (sorry its a bit messy, had to change some variable names around) test('Sers are verified', async t => { const IconArr = Selector('#testtable .test'); var count = await IconArr().count; var myArray = await IconArr(); const classConsts = ["testClassA", "testClassB", "testClassC"...

Trouble understanding Functions in C

All body content moves up and below the navigation (HTML & CSS)

It worked fine at first but then I implemented a lot of Lorem Ipsum text. All the content just slides up and below the navbar. I've attached a JS fiddle to explain.

Having trouble with parsing specific data from log file

By Ritesh Sahu - October 31, 2020

I have an assignment in which the main task is to report suspicious activities within a log file. There are several other problems I have to address, but the one that I want to focus on the most is "suspicious activities" (if I can get a grasp on this then more than likely I'll have a lightbulb to help guide me on the rest). The way this is supposed to be achieved is to keep up a count for whenever a user logins between 12:00 am to 5:00 am. Once a user has been marked for being suspicious, the users' name, their email, and the domain name should be present as output information. I have never worked with log files before and this is my first dealing with one using Python 3 (specifically PyCharm). So far it has proven challenging because I don't know where exactly to start this assignment. I originally planned to use regular expressions to match specific text in the log file and dictionaries for keys, but I wasn't sure if this was the correct frame of mind in t...

How to add a link to open a file without a Win10 security warning in iTextSharp v5

By Ritesh Sahu - October 31, 2020

When creating a new PDF file using iTextSharp I am able to create a link in the document using the .SetAnchor method that navigates to the specified URL when clicked, such as anchor.SetAnchor(...some URL...); However, all I really want the click to do is open or execute a specified file on my local Win10 machine, and this also works if I merely specify the file instead of a URL, such as anchor.SetAnchor("notepad.exe"); The issue is that I must use iTextSharp to create many of versions of the PDF file, with each version having a different file name itself as well as a different name for the file the link opens. Although I have no problem getting this to work, the annoyance is that whenever I click the link in a new version I get a "Security Warning" popup from Windows wanting to know if the "connection" should be allowed. Because the warning mentions a "connection" I get the feeling there may be a method something like SetAnchor that will pro...

I'm running into a pretty confusing situation here: if ((a.length = 0 || b === null)) { this.noNotif = true; console.log("1"); } if (a.length > 0 || b === null) { this.newNotif = true; // this.noNotif = false; console.log("2"); } else { if (a.length === b.length) { console.log("No New Notifications"); this.noNotif = true; } else { console.log("New notifications"); this.newNotif = true; } Console logging a.length returns 0 and 'b' is null However, the issue is that somehow both of the first two if-statements' conditions are being met. noNotif and newNotif both display a Vue components and both are showing up currently. Some background information about a & b 'a' is supposed to be data from an API that is fetched on page load. 'b' is supposed to be a localStorage object array The fi...

Can I use python - aiohttp inside of a GCP cloud function? [closed]

I'm trying to route/divvy up some workload to other cloud functions they all take roughly about the same amount of time, but I have to invoke them synchronously. I tried setting this up, and I followed someone's advice when implementing it with Flask to instantiate my loop outside the flask context because it needs control of the main thread(to return too), and everything still seems to be executed synchronously, I just need to gather up some responses in an object. this simple I/O problem doesn't seem to work on GCP Cloud Functions.

Is there a way to transform data in Stata from a single observation (e.g. # of patients experiencing an event) into many observations?

By Ritesh Sahu - October 29, 2020

I'm trying to efficiently use Stata to estimate standard errors around a proportion of patients experiencing an adverse event in a model we are adapting. An example dataset: n = 74 a = 56 b = 18 Where n is the number of patients, a is the number of patients experiencing an event and b is the number not experiencing an event. When the data is in this format, I note that using ratio myratio: a/n Returns a proportion (a/n) but does not estimate a linearized standard error. Manually converting the data into "long" format however fixes this issue. Long format being: No. observations = n (74) n = 1 for all observations a = 1 if index <= 18 else 0 b = 1 if index > 18 else 0 It's been a while since I have used Stata, is there a quick way to do this? I can't even remember how to extend the length of the dataset to the number of samples N ! from Recent Questions - Stack Overflow https://ift.tt/2J8YRGA https://ift.tt/eA8V8J

SIMD support at runtime

By Ritesh Sahu - October 29, 2020

I was making a XCode obj-c application, and I decided to turn on AVX2, through XCode's Enable Vector Extensions option. I started up my app, but it crashed. After a few hours I figured out that the issue was my Mac actually didn't support AVX2 (third gen i7). The thing is, I still expected it to work because I had commented out all of the lines of code that used AVX2 instructions. That meant that there was NO avx2 code even IN my app, I just had AVX2 support on. I was under the assumption that AVX2 was not used until I actually called the functions? My question is: How do I get an app that was compiled with the AVX2 instruction set but had conditions at RUNTIME that checked if the machine supported AVX2, and if it didn't, then there would be NO AVX2 instructions activated? from Recent Questions - Stack Overflow https://ift.tt/3kDc8VZ https://ift.tt/eA8V8J

Vault wrapping token - number of usage

By Ritesh Sahu - October 29, 2020

We are facing issue with fetching secrets from Hashicorp Vaullt. Client is actually using role_id and secret_id to auth in Vault. We also use wrapping function for secret_id, so once secret_id is fetched from Vault, it's wrapped and has to be unwrapped to get real secret_id. Now problem is that wrapping token obtained from Vault has number of usage 1. Meaning that secret_id can be unwrapped only once. When we try 2nd time to unwrap, it is failing. And reason is number of usace for such generated token which is 1 by default.

How comes the lifetime of a local variable inside a function be extended?

See the code below. v1 is local variable inside a function. Accordingly, after leaving this fucntion, this variable should be killed.
