            pickerinput as filter disable all not disabling button using shinyJS
            Asked 2021-Jun-12 at 00:58

            hope you are keeping safe.

            I've searched for similar issues but without success.

            My code is 5k lines long so posting it is a no go.

            I'll try to provide as much info as possible.

            In a nutshell, I have some pickerInputs working as a reactive filters for a rhandsontable object.

            I have a Save Button so users save their input.

            My initial strategy had an Achilles heel which was that saving with filtering on would overwrite all the data in rhandsontable.

            So, a quick workaround was to add an observeEvent where the Save Button (by using ShinyJS) is only enabled when the pickerInput has all options selected.

            So far, so good but I noticed a strange behaviour: initially if we click "Deselect all" in pickerInput the Save Button is disabled but by clicking "Select All" (which enables the Save Button) and then "Deselect All" then the Save Button is not disabled.

            My observeEvent code below.

            Does anyone seem this behaviour before?



            Answered 2021-Jun-11 at 18:22

            To fix your issue, you can enable the save button in a separate observer, and not inside the observeEvent. Try this



            How to create ODBC "DSN" for cross-platform testing?
            Asked 2021-Jun-06 at 02:22

            I need a simple ODBC test scenario on WIN which I can configure very simply and be assured it is working in support of another question at Unix.SE.

            In a nutshell I'm trying to setup a PyODBC/Python script connection from Debian 10 ( to Windows 10 in KVM/QEMU virtual system (

            First, on the Windows 10/KVM, I see the ODBC Data Source Administrator has a tab File DSN and Microsoft Text Driver. Can I use FileDSN to test Python PyODBC connection to ODBC using a simple CSV file in place of Server?? (My research with ODBC only finds running server instances).

            Next, what I tried:

            • On Debian I installed ODBC Microsoft driver for Linux.

            • Shutdown the Windows 10 firewall, and I can ping in both directions:

              $nmap -p 22 # Deb to Win

              > Test-NetConnection -p 22 # Win to Deb

            • On Windows 10/KVM I added a FileDSN with Microsoft Text Driver. I created a CSV file (odbc_test_01.csv) with simple header and one row of data (IE. {'ID' : 1, 'NAME' : 'FOO'})

            • Created a Jupyter Notebook to make testing easier. Here is my connection string and the results:



            Answered 2021-May-02 at 13:25

            An ODBC "File DSN" is not a driver for accessing data in a file. It is a way to specify a DSN (connection information for a target database) as values in a standalone file instead of in a standard configuration file on Linux (e.g., /etc/odbc.ini) or in the Windows registry.

            If you need to "clone" a Windows DSN entry for use in a Linux environment then you may find my dump_dsn utility helpful. It retrieves an ODBC DSN from the Windows registry and presents it in a form that you could use to recreate the DSN on Linux.

            For example, say I had a DSN named "mssql199" on Windows and when I ran dump_dsn.to_text("mssql199") on it I got



            How are people implementing immutable data structures in JavaScript when the language doesn't offer any obvious way of implementing immutability?
            Asked 2021-Jun-03 at 21:09

            So I decided to tryout functional programming because people say it gives you more control over the programs that you write, it's extremely testable, and it makes code more readable & easy to follow — who wouldn't want that..?

            Obviously I decided to try writing a program using the functional paradigm. I got stuck, nearly just as soon as I decided to try writing the thing. I couldn't really figure out how to make all of the program's data immutable. My first thought was to use all const declared variables, since a const variable cannot be re-referenced after the initial assignment, however; I found out that implementing an immutable data structure is quite different from declaring several const variables to store a programs state in. It became quite clear to me that I was going to need immutable objects, with immutable properties, and so forth. After attempting to create an Immutable data structure (example is at the question's bottom). I concluded that that JavaScript doesn't really have a way of implementing Immutable data, at least not a way that is obvious. And now here I am, scratching my head...

            What I would like to know is:

            "How are the people, who are writing JavaScript programs, using the Functional Programming paradigm implementing immutable data structures when the language doesn't really offer any sort of way implementing immutability?

            EDIT: I want to be as clear as possible, because I have struggled with clarity in some of my past questions, so I am just going to sorta meta-explain what I am asking for:

            In a nutshell, what I would like to know is: How does a person implement immutable data structures that work for the functional programming paradigm. An example of Any immutable data structure will suffice, or even an immutable object. If the answer involves use 3rd party libraries, other languages, or any other tool that would be great, and an example of what code using those tools might look like would be really excellent.

            Below is some code, where I was trying to hack a JS object into being immutable. Its not good code, in fact it throws an error, but it demonstrates my mindset, and what I am trying to solve.



            Answered 2021-Jun-03 at 00:44

            Welcome to Functional Programming!

            One solution is using ES6 class. getter returns property's deep copy, setter throws error.

            Defining user variables in stored procedures / routines for MySQL 9.0
            Asked 2021-Jun-03 at 16:40

            According to the MySQL 8.0 deprecations notes, starting MySQL 9.0 the definition of user variables with DECLARE (e.g. DECLARE studentID INT) will be deprecated:

            Support for setting user variables in statements other than SET was deprecated in MySQL 8.0.13. This functionality is subject to removal in MySQL 9.0.

            Already nowadays MySQL 8.0.25 raises a warning:

            1287 Setting user variables within expressions is deprecated and will be removed in a future release. Consider alternatives: SET variable=expression, ..., or SELECT expression(s) INTO variables(s).

            Therefore, I would like to understand how to properly replace DECLARE with SET. Let say, I have the following variables declared:



            Answered 2021-Jun-03 at 16:40

            The deprecation warnings are not clear, and are easily misunderstood.

            The DECLARE syntax is not deprecated. I think the authors of the release notes do not consider that a method of "setting" a variable. Admittedly, it does set an initial value for a declared variable, by using the optional DEFAULT clause. But I still interpret it as a statement that is not counted as one that is deprecated.

            What is deprecated is setting variables as a "side-effects" in expressions like this:



            Is a good idea pass decoded jwt data via express req parameters?
            Asked 2021-Jun-03 at 01:46

            In my NodeJs application im using jwt to manage the user session, inside a jwt token i store user_role and user_id. This is my route:



            Answered 2021-Jun-03 at 01:46

            Verifying and decoding JWT are two different things. When you verify, it's checking for its integrity, ie making sure it has not been tampered with, while decoding JWT means converting from base64 to readable format (UTF-8?). So it doesn't have to be verified twice.

            Assuming you sent your token in headers as "token":"base64encodedJwt", then after successful verification, whenever you need user_id, you can then simply decode the JWT. Use some JWT decode library.



            Retrieve ID after pushing to SharePoint list using React PNPJs
            Asked 2021-Jun-02 at 06:07

            I'm building a SharePoint SPFx react app. In a nutshell, the user fills out a form that I created. When the user hit's submit, using PNPJs: I'm adding the item to a list called Request.

            From there I want to send an email that contains the URL link to that item they created. Right now, my code adds the item to the list and I'm able to send an email with no problem. However, I want to get the ID of the item that was just added to the list, so that I can add it to the email.

            Here is a striped down snippet of my function that adds items to the Request list.

            Macro Annotations in Scala 3
            Asked 2021-May-31 at 11:32

            The following is a quote from Macros: the Plan for Scala 3 from more than 3 years ago:

            For instance, one will be able to define a macro annotation @json that adds a JSON serializer to a type.

            Any idea how/if this is actually possible in Scala 3?

            More generally, is there anything in Scala 3 that can provide "Macro Annotations" functionality? The following is a quote from Macro Annotations - Scala 2.13:

            Unlike in the previous versions of macro paradise, macro annotations in 2.0 are done right in the sense that they: 1) apply not just to classes and objects, but to arbitrary definitions, 2) allow expansions of classes to modify or even create companion objects



            Answered 2021-May-31 at 11:32

            As of June 2021, macro annotations are not supported in Scala 3, and they are not mentioned anywhere in the doc.

            Right now, if you'd like to generate methods, classes or objects, I believe you have to use scalameta or write a compiler plugin.

            Obviously, this situation might change in the future, macro annotations were not part of Scala 2 at the beginning either.



            Hide free shipping when subtotal is greater than 0 in WooCommerce
            Asked 2021-May-28 at 09:33

            I'm using Free Product Sample for the WooCommerce plugin and trying to set conditional free shipping only for a Sample product, sample product cost is 0 and therefore I'm trying to hide free shipping unless the order subtotal amount is 0.

            To put it in a nutshell:

            I want to offer free shipping only for sample products and, the free shipping method should only visible for a product having subtotal = 0

            Extract function from addEventListener
            Asked 2021-May-23 at 16:22

            In a nutshell, I have 3 divs that will have their bg colour randomly changed when clicked. They can only be clicked once, hence the removeEventListener. Am I just trying to over-complicate things?

            I have 3 event listeners that all use the same function, but each with its own arguments:



            Answered 2021-May-22 at 18:12

            Since the body of the functions are different, I don't think there's a way to have a singe outside function that removeEventListener can be called for. But there is an easy way to simplify things: use { once: true } so that the listener can only be called once, no need for removeEventListener at all.
