            Data disappears on refresh, but loads when modifying code in React Web App
            Asked 2022-Apr-03 at 23:14

            First time poster, so I apologize if I don't do things correctly. I am also new to React so bare with me, I will do my best to describe the problem.

            I have a dataset that consists of school classes in json format. I am using axios to grab the data. The data consists of an array of objects which contains information about each class. I want to break up the classes so that they are separated into 4 different arrays based on what school year you are in (freshman, sophomore, junior, senior). I then want to display these classes on my web app.

            Here is the code below:

            You must not modify the states directly as you are trying with freshman.push(item), instead use setFreshman([...freshman, item])

            But in your case, this won't work because the app only updates the states after all forEach loop, so it will keep getting the initial state (the empty array) from the states and adding the current item, the only one in the end.

            So one solution is using temporary variables to keep the items and once forEach has finished you update the states.

            Why does C program skip my if loop for programming raspberrypi?
            Asked 2021-Nov-22 at 14:36

            I am trying to do a c program that programs to raspberrypi to turn on/off/blink the LED diode in a breadboard. There is a button on the breadboard that I use the digitalread function to "click" it. Ideally, the program should work by clicking the button once, the LED will light up. Click again and it will turn off the light. Click once more and it will blink a few times and the loop will repeat. However, when i use this program, it seems like the first 2 if statement are skipped. And when i clicked the button, it only blinks. Does anybody know why?

            I helped you yesterday with this UI, this is an extension of my suggestions.

            First match the id of the menu items to the id in your toolitems then you can use Array#find() to get the object needed to create your new element. I simplified this only getting some text.

            I also used a global draggableOptions object that you can pass to the new element draggable method. The stop event uses the suggestions I provided yesterday of how to loop over all the items to create an array of objects.

            The following is not well styled and the items are very primitive but the dragging works as does the logging of array of items meta data that you can store

            How to properly connect a scalar to a vector entry?
            Asked 2021-May-27 at 12:36

            We're searching a way to connect scalars (as an output) to vector entries (as an input).

            In the "Nonlinear Circuit Analysis" example, there is a workaround in the class Node which loops over the number of scalars and adds each scalar as a new input. In the class Circuit, the added inputs are then accessed by their "indices" (e.g. 'I_in:0').

            In our case, this loop must be integrated by a new Component, which solely loops the new inputs. This is why we'd like to avoid loops and directly use vector and matrix operations. In terms of the Circuit example, a way to achieve this would be to use some kind of target indices (see tgt_indices), which are not implemented (yet 😊). In this case both classes would look like this:

            ANSWER

            Answered 2021-May-27 at 12:36

            You are correct that there is currently no tgt_indices like feature in OpenMDAO. Though it is technically feasible, it does present some API design and internal practical challenges. If you feel strongly about the need/value for this feature, you could consider submitting a POEM describing your proposed API for the dev-team to consider. You have a start on it with your provided example, but you'd need to think through details such as the following:

            • what happens if a user gives both src_indices and tgt_indices?
            • What do error msgs look like if there are overlapping tgt_indices
            • How does the api extend to the promotes function.

            In the meantime you'll either need to use a MuxComponent, or write your own version of that component that would take in array inputs and push them into the combined matrix. Its slightly inefficient to add a component like this, but in the grand scheme of things it should not be too bad (as long as you take the time to define analytic derivatives for it. It would be expensive to CS/FD this component).

            First of all, I tried running your code which gave me SMTP Class not found error, so I added another use statement use PHPMailer\PHPMailer\SMTP; to avoid future errors.

            Then, I got the same error and solved it by generating an App Password, which was required for 2-Step Verified accounts.

            I didn't really change your code, but I ran it in localhost.

            If nothing works, you can set the debug mode $mail->SMTPDebug = 3; in order to get more details, and also I recommend checking out the SSL/TLS protocols, which I saw it from this thread: PHPMailer: SMTP Error: Could not connect to SMTP host

            How to configure the modem connected to usb in linux?
            Asked 2021-Feb-02 at 11:37

            I have a separate Linux board built via Buildroot. now I would like to connect the modem to the usb port on the board. from the modem side I have a DB9 socket so I used the RS232-USB adapter. However, after connecting, it does not detect the device and the diodes on the adapter show that there is no data exchange (TxD and RxD). The "Active" LED is also off. I found an article on how to configure a USB modem:

            https://www.maketecheasier.com/setup-usb-modem-linux/

            but I have no access to the GUI unfortunately. I have to do this at the terminal. How to configure and connect to the modem? When I connect the modem, I have no additional devices in the path /dev/

            ANSWER

            Answered 2021-Feb-02 at 11:37

            If your RS232-USB adapter is recognized by the kernel, it will create a virtual UART device usually named /dev/ttyUSB0 - this is your device to the modem. Note that nothing happens automatically to a modem you connect to the RS232-UART adapter, it's up to you to set it all up correctly.

            To verify that the modem is OK and the UART link works, run a serial terminal and send it a few AT commands. I can recommend screen as a really simple serial terminal, e.g.: screen /dev/ttyUSB0 115200 (use sequence "Ctrl+A, \" to quit). Or minicom, which is the original modem client, but using this one requires reading the docs.

            If your manual tests confirm that the modem is OK and can go online, it's time to configure a dial-up service. This depends on which network manager you've chosen. If all you have is the good old ifup/ifdown scripts in /etc/network/ then either use raw pppd or set up some helper like wvdial. Google is full of practical examples.

            If you're running something like NetworkManager or connman/ofono, follow their documentation.

            1. CapacityMode can have values 0 to 3, but if your device only supports mode 0 (capacity measured in milliamp-hours) or mode 1 (capacity measured in milliwatt-hours) then I think it is ok to have a 1-bit wide field to record this. You could even define an 8-bit field that only stores the values 0 or 1 even though it could hold values up to 255.

            2. I think the authors of the examples may have been trying to align the fields into 8 bits by making each of the 4 status bits 2-bits wide - so 0, would be stored as 00 and 1 would be stored as 01 in the report. Or it could have been a typo - I have seen many other examples in the USB specifications that have errors in them.
