QUESTION
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:
...ANSWER
Answered 2022-Apr-03 at 22:32You 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.

QUESTION
ANSWER
Answered 2021-Dec-21 at 09:48You should be using navigator.mediaDevices.getUserMedia
. The one in your first example snippet. The second example snippet is deprecated.
The issue here (from what I can see) is that getUserMedia
is suppose to request permissions everytime it is called. So the prompt is expected.
You need to store the stream in a variable, and that variable needs to be declared outside of the event handler.
QUESTION
I am working on the implementation of the serial driver of the EEG (time-series acquisition device). The device encodes the data with 12bits x 26 total channels with a sampling rate of 200Hz
The serial data stream consists of signalling byte 0xA0 followed by 45 bytes that carry the data for 26 channels, each encoded with 12bits.
But here is the catch, these 12bits are not in fixed positions in the 45byte block. The first byes use only 4 LSB, whilst the rest 44 7 LSB.
To make this more illustrative I will try to represent it graphically below. Suppose that we have started the amplifier and it always gives us 4095 (max int value represented with 12bits) for all channels (so we have all "ones" for the data), then we have something like this:
a0 0f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f a0 next sample...
This has to be mapped to the int(1,...,26) with values 4095.
So, I made a python code, that first finds the beginning of the block, then it saves everything in one int/long, then I removed the bits on fixed positions, append 8 most significant 0 bits to make a 16bit representation and convert the byte array to a list of integers.
That works fine, but the problem is the speed. Seems that the code takes a considering amount of time for a single sample and it has to do it 200 times in one second. Let's include some other delays of the real serial read methods, everything has to stay much below 1sec for all 200 samples

QUESTION
So I'm making this Java application that saves products in a warehouse system and lets the customer purchase the available items, and I'm pretty much done, but this one little error in output I've been getting since the start keeps bugging me. When the program asks at first how many products the customer would like to purchase, it shows pretty much ALL the messages included in the while loop below. I know this is probably a very simple mistake to fix but I cant seem to find a proper way to fix it. This is the class:
...ANSWER
Answered 2021-Jul-23 at 20:26Try to add "in.nextLine();" right after " int numberOfProducts = in.nextInt(); ". I think the problem is the program read an empty line before/after it read to the input value, that is why it goes directly to your "testing" while loop and display these messages
QUESTION
I have 2 monitors on my desk connected over display-port and I got a tv connected over hdmi.
I am looking for a way to use audio over my hdmi-port without displaying on the tv. The thing is that my tv is connected to an amplifier which is connected to my pc.
tv -> amp -> pc
I want to be able to get my audio to the amplifier while my tv is should be disabled. It's an YAMAHA RX-V775 and HMID-passthrough is enabled.
I tried different xrandr-commands to get this working but I was never able to get the audio working without displaying on the tv (tv doesn't need to be turned on, just enable by xrandr).
This is my current command:

ANSWER
Answered 2021-May-19 at 07:57After a long time searching on the web, I found a solution to this problem. As mentioned, audio won't work when the display connected over HDMI is disabled. Futher more I didn't wanted to expand my screen to the other display because I would only want to work on my desk while using audio over hdmi.
The solution is to simply run an xrand command, which will mirror my primary screen on the TV. This is possible even if the TV is turned of. The tricky part is, that xrand might have diffuculties to add custom resolutions especially when using a nvidia gpu and driver. Here is the working command:
QUESTION
I'm using manjaro-linux-i3 with polybar and I'm currently working on my multiple monitor setup. I have a TV which I normally use with the amplifier it is connected to. In addition I have my desk with a triple monitor setup which I normally use with my headphones for audio output. One of my screens is in portrait orientation which always messes up my login screen.
I'm able to change my audio ouput and my active monitor as I wish. But I want it to be more efficient. At the moment I'm using arandr to change my monitor and pavucontrol to change my audio output when needed.
I want that my login manager(lightdm) is always displayed correctly on my monitors(even on the portrait one). It would be nice if anybody could give me way how to combine changing monitors and the audio output in one blow. So that I don't have to this every time manually.
...ANSWER
Answered 2021-Apr-27 at 14:00I have similar setup and I got everything working what you might want if I understood you corretely.
If you setup everything right, then your loginmanager should always be displayed on the monitor which is active at boot and you can switch your monitors&sink with a simple keybind.
First, you can add a script to lightdm to config your monitors so that everything is displayed correctely. But be aware that a broken script can leed to the effect that your loginmanager won't be loaded correctly (blackscrren).
in /etc/lightdm/lightdm.conf
you can define a script at #greeter-setup-script=
. Simply uncomment the line and add the path to your script.
An easy way to config your monitors the way you want is to use arandr. Simply config your monitor the ways you want and save the setup. You will be saving an usual xrandr command, which can be used in your script.
Here is my script. It is very basic and actually only checks if a monitor of my desk is active. If so, it initialises the monitors of my desk. If not, it initialises my tv. It also sets the audio output I use with those monitors.
To get a list of all active monitors use this command:
xrandr --listactivemonitors | awk '!/Monitors/ {print $4}'
To get a list off all sinks(audio output) use this command:
pacmd list-sinks | grep -e 'name:' -e 'index:' | awk '{print $2}'| awk '{print substr($0, 2, length($0) - 2)}'
Now you can change my commands (sink and monitor names) with the onces you need. You can execute the script in the terminal so get feedback of the choosen sink and monitor (for testing). Don't forget to make your script executable else it won't work.
I got a similar script to manually change between my tv and my desk (mirroring scrrens, duplicate, tv-only, ect)
It too changes the sink according to the selected monitors. As you are using polybar too, you might notice that I relaunch polybar with sh /home/lluks/.config/polybar/launch.sh
This is the script.
It ensures that my applets are displayed on the main monitor as poylbar can only display them on one monitor. This is archieved by using a 2 diffrent bars for poylbar.
For this script to work, you need dmenu and rofi. If I remember corretely, you also need Font Awesome for the icons.
QUESTION
I'm trying to do a sentiment analysis using hash_sentiment_socal_google in Sentimentr. Looking through the responses, I've noticed that one word responses of "unsure", or "unknown", get an average sentiment score of -.5. And "yes", gets .8. I would like all of them to show up as 0, or neutral.
I don't actually see any of these words in hash_sentiment_socal_google, so I'm not sure why these responses are being assigned sentiment scores. But I just figured I could add to the key with the following code to set to 0:

QUESTION
I've tried searching Google and was wondering what language microcontrollerare programmed in? Can you use Java? Like say on an amplifier you have a menu to increase or lower bass and treble, displaying firmware version and so on. I'm assuming they would be flashed with a special tool.
Also is Java or C++ the better language?
...ANSWER
Answered 2020-Dec-09 at 11:45I notice that you are still relatively new to the subject. Unfortunately, I can't give you a direct answer, because the topic of hardware-oriented programming on embedded systems is a very deep and complex topic in computer science.
But in general: When programming microcontrollers (or microchips, as you call them) there is usually not much object-oriented programming. Things like generic programming styles etc. you search in vain. The rule is: lean, fast and direct languages that allow a reasonable amount of freedom in programming (e.g. C, C++) are used here. Java (or C#, if the architecture with .Net Frameworks allows it at all) are not suitable for this.
But this does not mean that it is not possible to develop such applications with Java and C#. I had the pleasure to write a highly available application in C# for a microcontroller. This is possible, but not pleasant.
If you want to get first impressions in this field of computer science, I recommend to buy a Raspberry Pi and develop your first programs on it. Based on this you can then add additional hardware and program it (e.g. an LCD display or a few sensors). From then on you can jump to other microcontrollers (like the STM32).
