I want to get current disk info Read Speed and Write Speed not max speed I/O
like image above, read speed = 0; write speed = 8.8MB/s
Please, anyone can show me a command can get that info.
Just to begin with, this class will give you everything you need that you desire to have:
Get-WmiObject Win32_PerfFormattedData_PerfProc_Process
But my preference is
1) powershell-is-king-Measure-disk-performance-for-iops-and-transfer-rate
2) 2 Functions for IO
Hope it helps

It has been over a year since I'm using VSCode. Almost every day I search the web for ways to display the time taken (speed) and space taken(during execution) by my program. This info is very important. But unfortunately, I haven't found(or missed) a way to display these metrics. VSCode is cool to use and lightweight etc. etc., but these metrics were visible by default in some other IDEs (like codeblocks). Some extension or some setting I missed in the many articles I went through. If someone could help me out here, I'll be super grateful.
Thank you in advance

You can add this psutil.Process(os.getpid()) at any function(at main thread to see entire memory usage of the program) that you wish to see the status byprocess.memory_info().rss in the running time Memory usage: 0.5774040222167969. Also check this code for to know the program runtime.
I work in industrial automation and the functions of automation processors and software are locked down. I'm trying to sample and collect an analog signal at as fast of a rate as I can, <=10ms.
I have tried VB into excel, using a DDERequest and incrementing a delayed loop.
Application.Wait is too slow (1s)
"Private Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)," had the most promise, but too slow (100ms). It can be pushed faster, but this is on my computer, and then grabbing the float from the automation processor over ethernet... 100ms is the fastest without distorting the "real-time sample."
I have tried a Python module that pulls the float from the IP traffic. (Still over ethernet and too slow)
#x parameters
sample = .001
iterations = 1000
#Collection
for i in range(iterations):
# read the GPIO
float1 = SomeGPIOCommand(pin#)
float2 = SomeGPIOCommand(pin#)
# add the result to our ypoints list
ypoints1.append(float(float1.Value))
ypoints2.append(float(float2.Value))
#x
t = i*sample
xpoints.append(float(t))
# pause
time.sleep(sample)
#Plot
plt.plot(xpoints, ypoints1, 'c-', label='target' ) plt.plot(xpoints, ypoints2 ,'r--', label='actual')
OR is this fast of a sample rate going to require code under an IDE? The key here is matching the time stamp, in ms, exactly with the measured value.
I'd like to get there without an IDE, I just have no clue where to start, especially with the pi.
I have yet to see any example with this performance level.
Appreciate any help!

No. A fast sample rate doesn't require coding under an IDE. Whether or not the code is developed under an IDE will have no bearing on sample rate.
I'm building my first game in Unity using my limited knowledge, youtube tutorials and troubleshooting on google and even though i have a couple of idea's on how i could do this i can't seem to get it to work.
For one of the larger levels i need speedups that boost the players speed when driving over them. This is seen in a lot of racing games but to clarify i found this video where this type of boosters is used https://www.youtube.com/watch?v=GQ1FLPBw1FE.
I've tried making a script that would remove my current movementscript and replace it with a faster one, i've also tried making a script that would detect collision with the player(tag) and add force to it. Both didn't work i've also been thinking about using timescale but i don't want the rest of the world or scorecounters etc to speed up, just the player.
this is the basic script i am using for playermovement.
#pragma strict
function Start () {
}
var forwardSpeed:float = 35;
var turnSpeed:float = 1;
function FixedUpdate () {
var forwardMoveAmount=Input.GetAxis("Vertical")*forwardSpeed;
var turnAmount=Input.GetAxis("Horizontal")*turnSpeed;
transform.Rotate(0,turnAmount,0);
rigidbody.AddRelativeForce(0,0,-forwardMoveAmount);
}
and since the player's vehicle is customizable i also want to make an upgrade that permanently increases the players base movement speed by a certain amount. i would do this by putting in an if(upgrade is active)
increase its speed by x;
this would have to stack with the booster
if you guys have any idea's on how i could do either or both of these things please share and thanks a lot in advance!
Instead of replacing the movement script with a faster one, add in an extra variable to the players movement.
var forwardMoveAmount=Input.GetAxis("Vertical")*forwardSpeed * boostSpeed;
Where boostSpeed regularly equals 1, but when the player collides with a speed boost push the value up to something higher like 2, then after a short while it gets reset to 1. As for the player speed upgrade, follow the same logic, except permanently, so it would look something like this:
var forwardMoveAmount=Input.GetAxis("Vertical")*forwardSpeed * boostSpeed * upgradeSpeed;
I can't put my finger on why it's doing this, but since a few days help takes a lot of time to show. Either inline (selecting a function, selecting "help for"), or by using the commands doc or help. The command doc cmdname takes about 10 seconds to show the help window. I did, taking fwrite as example, try profile on;doc fwrite;profile viewer and digging through the rabbit hole I arrived on a private java matlab method which is taking forever:
tic;
com.mathworks.mlwidgets.help.HelpUtils.getDocCommandArg('matlab\fwrite', true);
toc
Elapsed time is 9.993832 seconds.
Any idea what could be causing that issue? It also happens in safe mode, with no other running programs than MATLAB. I'd try a complete reinstall of MATLAB, but if I could avoid that that'd be great.
There are a couple of things that might be contributing to this issue, but given the information you've provided it's hard to say exactly what is going on.
When the R2012b help system initializes, it does a few tasks that can sometimes introduce a noticeable delay, mostly related to determining which MathWorks products are available and how you have your help preferences set up. 10 seconds would be unusual, but there is a possibility that this is what's causing the delay. If you're seeing the performance hit on your first use of the help system, but not again in the same MATLAB session, this is the likely cause. This behavior is improved in R2013a.
Other than initialization tasks, the Java call in question is a relatively straightforward search against the same search index that is used for searching the documentation. If you are finding that searching the documentation in the help browser is slow, this would be a hint that the performance issue lies somewhere within the help system's search functionality.
In either case, your best bet is probably to contact MathWorks technical support. It is likely that we can take a closer look at this and possibly come up with some sort of fix.
The problem has been solved with input from mathworks support:

After that, thinking it was a problem with a temp file being locked, I closed Matlab, went into AppData\Local\Temp\ and cleaned all the temporary files in it.
>> tic;
reader = org.apache.lucene.index.IndexReader.open(fullfile(docroot,'helpsearch'));
searcher = org.apache.lucene.search.IndexSearcher(reader);

Either it's the cleaning the temp files or the reference to internal java classes org.apache.lucene* that did the trick, but here it is, now doc is fast again.
I'm trying to design a storage system where excess energy goes into it. There is a cap of a maximum storage size for the system. I am struggling to work out how to code this in matlab.
Currently im using a function similar to this
max_storage = no_tanks*tank_size
if cumsum(excess) > 0
storage = cumsum(excess)
elseif cumsum(excess) < 0
After that I am confused how to continue writing the code. Any help would be greatly appreciated
Attempt at mind-reading, while awaiting an update to the question.
To limit the storage size to max_storage, you need to have some code like
storage = calc_storage(excess); % or whatever
storage = min(storage, max_storage);
Don't forget to finish your statements with ;, and if you need to use cumsum(excess) lots of times it is better to assign it to a variable rather than calculating it over and over again.
