My first Alexa skill is almost ready to go public, but I seem to have gotten myself a bit tangled... I'm sure I'm missing something obvious.

I asked Amazon to Certify But Not Publish this skill, to check that I wasn't missing anything obvious. They did so. Great, but...

Since then, I've uploaded some slightly modified models. Since I'm ready to go, I went to Validation and punched Certify again. It told me "You cannot submit this skill for review because it has a ‘Certified’ version. Publish or withdraw the previously ‘Certified’ version to submit this skill for review."

Submission shows a warning that the most recent validation failed (for the above reason).

OK, I understand. But I'm not sure how to do either of those.

When I look at Version History, I do see the previously Certified skill version. However, I can't see how to either publish or withdraw it!

A quick websearch hasn't found anything which clarifies this for me. I MUST be missing something obvious -- these operations are on a different page, or something like that. Could someone point me to where I can perform them?

(Yes, I looked at https://developer.amazon.com/en-US/docs/alexa/devconsole/test-and-submit-your-skill.html. That doesn't seem to address my situation of having a certified version, having a new version which couldn't yet be certified, and not being sure how to go either forward or backward.)

I am trying to publish jar file (output of a gradle project) to jfrog/artifactory. The project is successful when I execute gradlew build or gradlew build artifactoryPublish. I also see on console that Build successfully deployed. Browse it in Artifactory under https://... but when I go to Artifactory the nothing is there. I tried following the jfrog/artifactory documentation, some questions on stackoverflow like this one and this one. Following is the snippet from my build.gradle

I'm getting error string index out of range when I getting simple text from post request and want to show data in array.

Working with java use Apache PDFBox to sign and certified, invalid certified if signature exist, with JsignPDF was able to certified when approval exist, the process is sign after that do certified (seal) document

Signature with JsignPDF

document after certified with JsignPDF :

the certified invalid with PDFBox

the function from PDFBox with some editing was to try :

I am using a template of a "certificate of completion" for online courses for my website.

On the template it has placeholder function names where presumably values would be pulled from database or elsewhere.

For example:

I’m doing some troubleshooting for a custom domain (purchased via Google). I’ve updated the custom resource record in Google, done the route 53 + AWS cert manager steps, and ran zappa certify (as well as zappa update). My first thought… is it supposed to show the AWS link after the custom domain: e.g.,

I am making a code which takes in jumble word and returns a unjumbled word , the data.json contains a list and here take a word one-by-one and check if it contains all the characters of the word and later checking if the length is same , but the problem is when i enter a word as helol then the l is checked twice and giving me some other outputs including the main one(hello). i know why does it happen but i cant get a fix to it

I wish to submit a form, but when the field is not entered, it should auto-point to that area. I have radio buttons. When it is not clicked, it should auto-scroll to the radio button area. When I execute my code, it is not autoscrolling to radio button but text fields are autoscrolling.

Whenever I try to submit the form, it is not autoscrolling,it only shows the error condition.How to fix this

Symbolic calculations performed manually or by a computer algebra system may be faulty or hold only subject to certain assumptions. A classical example is sqrt(x^2) == x which is not true in general but it does hold if x is real and non-negative.

Are there examples where proof assistants/checkers such as Coq, Isabelle, HOL, Metamath, or others are used to certify correctness of symbolic calculations? In particular, I am interested in calculus and linear algebra examples such as solving definite or indefinite integrals, differential equations, and matrix equations.

Update: To be more concrete, it would be interesting to know whether there are examples of undergraduate assignments in calculus and linear algebra that could be formally solved (possibly with the help of a proof assistant) such that the solution can be automatically verified by a proof checker. A very simple example assignment for Lean is here.
