QUESTION
There is a file with following contents:
...ANSWER
Answered 2021-May-19 at 20:19It seems someone wrote bytes in wrong way. Someone used str(bytes)
instead of bytes.decode('utf-8')
. Or maybe code was created for Python 2
which treats bytes and strings in different way then Python 3
.
if you can correct code which write it then you have to fix text

I wanted to get data from Bitmart's WebSocket (an exchange). I was able to subscribe to the WebSocket and get data back but it is compressed and according to the Documentation I am supposed to use zlib to decompress the data but when I tried to do it, it gave an error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcd in position 1: invalid continuation byte
This is my code:

QUESTION
I'm trying to load more than 20,000 records from MySQL to the Datatable in vb.net, but I got an error (fatal error encountered during data read), although I don't get the same error when I use the same SQL statement to get the data with "Where condition" to get fewer data and indeed I get about 6000 records without any problem or error, as I googled about the problem I found some expected solution like:
- set net_write_timeout=99999
- set net_read_timeout=99999
I changed them from variables of MySql but the error still, and in my connection string I set the Connect Timeout=500;
is there any suggestion about my issue? and how I can use (set net_write_timeout=99999) directly in my SQL statement that I use to get the data?

QUESTION
How to remove this warning I have this function in my code and showing the following warning !! Does my code work in same way if i remove -?
...ANSWER
Answered 2021-Mar-18 at 03:53You can use ESLint's no-useless-escape
rule, which will suppress warnings when you use escape characters that don't change the string's meaning. Also see this question and its answers.
As a bit of extra info, -
in a regex only has special meaning if it's inside of square brackets [ ]
and otherwise does not need to be escaped. None of the instances in your regex appear to be inside such brackets, so it's safe to say the regex will work the same if you do decide to just remove the escape characters.
QUESTION
When using os.urandom(64) it generates a string with 64 random characters, this works as intended but oddly when turning it, alongside other data into a list (I need to do this to writerow into a csv file) it turns the slashes into double slashes.
Normal Salt: b'\xfe\x82;o\xa6\x8e\xfeF]\x140\x02+\xe9\x82\xa0j\x0e\xe19n\x02\xa0_t\xb6\xa8\xe1u\xc6\x94\x9a\xb94P\t\x83\xe0\x0e&B\xda\xe5)62\xa3l\x807\xb6\xd8\x0bU\xd0\xf1\xe0\xf7R:\xbc\xfe\x86\x96'
Salt within the list: "b'\xfe\x82;o\xa6\x8e\xfeF]\x140\x02+\xe9\x82\xa0j\x0e\xe19n\x02\xa0_t\xb6\xa8\xe1u\xc6\x94\x9a\xb94P\t\x83\xe0\x0e&B\xda\xe5)62\xa3l\x807\xb6\xd8\x0bU\xd0\xf1\xe0\xf7R:\xbc\xfe\x86\x96'"
Code:
...ANSWER
Answered 2021-Mar-14 at 19:03When printing a list, the function used on each item on the list underneath is the function repr() which escapes backslash with double backslash.
However, when printing a string with print(str)
, it is the function str() of the object that is called.
You could try the following to understand:
print("this is a tab \t and this is a linebreak \n END")
print(["this is a tab \t and this is a linebreak \n END"])
As you can see, the first one formats the string (Using the str.str() function) while the second one does not (Using the str.repr() function).
Does this make sense?
However, it should not change the behaviour, just the display. The string Salt
is always the same, it is just not displayed the same way whether it is inside a list or not.

I am trying to debug an app on the Google Playstore so that I can see the requests that it is sending out. I've set up Charles Proxy on my computer to help me do so, but I am having issues with viewing requests sent out with https. My steps are listed below.
My Computer:
Manjaro Linux
My Phone:
Google Pixel 4a
Android 11
Not rooted
My Settings:
Using Charles v4.6.1

Here are my steps to allow the app use SSL through charles:
...ANSWER
Answered 2021-Jan-29 at 10:56Your network config there is within , which only applies for debug builds. Did you build the application in debug mode, or for production? If you don't build in debug mode then that config won't apply.
You probably want to use instead, which applies to all builds, not just debug builds. There's a full example here: https://httptoolkit.tech/docs/guides/android/#if-you-dont-have-a-custom-network-security-config.
If that doesn't work, then it's likely that there's some certificate pinning in place in the application code itself, independent of the network security settings. To fix that you'll need to manually edit the code itself. You can also try using https://github.com/shroudedcode/apk-mitm which has a selection of automated patches that disable many common manual pinning implementations for you.
QUESTION
I am trying to draw 2D metaballs using WebGL2. I render a bunch of quads with transparent radial gradient and gl.blendFunc(gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA)
to a separate framebuffer. I then use the resulting texture in a fullscreen quad, where I decide if pixel should be rendered based on it's alpha value like so:
ANSWER
Answered 2021-Jan-03 at 15:45I'm pretty sure the issue the texture your rendering to is 8bits. Switch it to a floating point texture (RGBA32F
) You'll need to check for and enable EXT_color_buffer_float
and OES_texture_float_linear
You say it won't work on mobile but you're using WebGL2 which hasn't shipped on iPhone yet (2021/1/3). As for RGBA32F not being renderable on mobile you could try RGBA16F. You'll have to check for and enable the corresponding extensions, EXT_color_buffer_half_float
and OES_texture_half_float_linear
. Your current code is not checking that the extensions actually exist (I'm assuming that was just to keep the code minimal)
The corruption is that your circle calculation draws alpha < 0 outside the circle but inside the quad. Before that was getting clipped to 0 because of the texture format but now with floating point textures it's not so it affects other circles.
Either discard
if c
<= 0 or clamp so it doesn't go below 0.
Note: you might find coloring faster and more flexible using a ramp texture. example, example2
Also note: It would have been nice if you'd created a more minimal repo. There's no need for the animation to show either issue
Update 2Something else to point out, maybe you already knew this, but, the circle calculation
