            A shared project can be created in Microsoft Visual Studio which acts a central repository that contains the source codes or files.

            The project itself doesn't require any references which can then be added as reference for version specific projects.

            When open the source code in editor, one can easily switch between the context of referenced projects to make sure everything's good in case there are any conflict due to different dependencies.

            The final project structure would then looks similar to:

            Product version Project type Newtonsoft.Json version All Shared N/A 1 Class library 10.0.1 2 Class library 11.0.1 3 Class library 12.0.1

            P/S: This feature has been around for quite some time and I just recently found out about it, hopefully the information provided helps!

            Difference between a serial driver and a tty driver
            Asked 2021-May-24 at 14:06

            So what is the difference between a serial driver and a tty driver?

            A serial driver makes no assumption about the kind of device attached, it merely sends and receives raw "bytes" (see note), and probably offers some way to configure the communication (which baud rate, how many data bits, what kind of parity scheme, what kind of flow control, etc). The device attached to the serial port could be a serial mouse, or a bar code scanner, or a printer, or ... - the serial driver doesn't care.

            Note: "byte" might not be a synonym for "octet" - e.g. it could be a group of 7 bits.

            A TTY driver is tied to the assumption that the device is an type writer with a keyboard. Note: For the history; before computers existed we went from "people waving flags at each other" (semaphores) to "morse code with a single key" (telegraph) to teleprinters/teletypewriter (see https://en.wikipedia.org/wiki/Teleprinter ); and when computers got invented the (mechanical/electric) teleprinters were simply replaced with (computerized) dumb terminals.

            Mostly; TTY is all about what bytes mean (and doesn't care much how the bytes are sent/received); and a serial driver is all about how bytes are sent/received (and doesn't care what the bytes mean).

            Is there any interdependence relation between them? I mean to write a tty driver should I write by first a serial driver, that will be a base to the tty driver or what?

            Crudely; a TTY driver has IO in 4 directions - getting key press info from local keyboard, sending bytes to remote whatever, receiving bytes from remote whatever, and putting characters on the local screen. For sending/receiving bytes with "remote whatever" you can use a serial driver; but (especially during development/testing) you could use anything else (TCP/IP stream, pipes, file IO, ...) instead - you don't necessarily need to implement the serial driver first.

            You were almost there. I found a few typos in your HTML code like the

            not having an opening tag, along with semantic issues such as not using
          • elements in your unordered lists. After updating the HTML, all that was left was to provide a background color for the containers which hold the nav menu items at mobile and tablet viewport widths (ie the two media queries). I added a stock photo to the background-image for demonstration.

            Lastly, updating your media queries to use px values instead of em. As @DCR mentioned, the em base value may change which in turn would cause your media queries to take affect at varying widths determined by the base value. Everything seems to match the desired output in the images you've included.

            If you would like the page content to not exceed a certain viewport width, just specify max-width on the and center it on the page with margin: 0 auto which creates 0 top/bottom margin and "auto" sized left/right margins to center the content. I also added a border and box-shadow to the body at "desktop size" so it matches your desired output.

            Dynamically generated hero banner text running beneath 3 action cards when text section is too long, trying to add styling to prevent overlap
            Asked 2021-Feb-23 at 14:53

            I have a dynamically generated hero banner that features a title and then body text underneath followed by three action cards that sit just over the bottom portion of the hero banner.

            My issue is that whenever there's a hero banner that features longer body text it runs behind the action cards as shown here:

            I tried adjusting the margin-bottom for the HeroText but it still just ran behind the cards. I'm trying to adjust the CardRow and the HeroText so that the CardRow pushes down in relation to how much text there is while still overlapping the HeroImage at the bottom but I'm stumped on how to do this.

            1. the cards wrapper is moved where the dynamic desc is being appended.

            With @kleopatra's help. My solution is to create a class responsible for parsing the date selected by the user on the DatePickers default choice box. Furthermore, the date picker is set to editable so that the user can also edit it manually. However, there is a restriction where a user can ONLY insert numerical value when editing manually, also I wanted to make sure that the user should input only valid dates.

            CoAP Client using nRF9160 + Zephyr RTOS: Proxy-URI length issues
            Asked 2021-Jan-10 at 10:29

            I am developing a CoAP client on the nRF9160 DK, running Zephyr RTOS. I am having trouble with longer Proxy-URI's; short URIs (268 characters and below) work fine and the coap message reaches the server as expected. However, messages with longer Proxy-URIs (269 characters and above) fail to go through for some reason. For example, with the following initialisation:

            ...

            ANSWER

            Answered 2021-Jan-09 at 10:26

            CoAP messages are typically limited by the application's buffer in size, and practically limited to one MTU (as IP fragmentation is rarely used together with CoAP). Unlike the message's payload, an option can not be split across multiple messages using block-wise transfer. On the Zephyr side, the error went unnoticed because you discarded the coap_packet_append_option result code.

            For the concrete case of this URI, you can work around the limitation using a larger message buffer (how that is done depends on how you initialized request in the first place).

            Note that transporting a JWT in the URI for authentication purposes is not how authentication is typically done in CoAP applications. If your HTTP server accepts TLS client certificates instead of CWTs, you may consider provisioning the proxy with a suitable client certificate (to be used when the CoAP client is authenticated properly, eg. using DTLS or OSCORE), and then use only the almost reasonably sized token-less path.

            [edit after question clarification]

            The lack of errors indicates a flaw in the Zephyr code, either Zephyr itself or the concrete network interface used (which should not silently truncate outgoing messages without letting the OS know), and would best be addressed inside the Zephyr issue tracker.
