According to Wikipedia, the ASCII is a 7-bit encoding. Since each address (then and now) stores 8 bits, the extraneous 8th bit can bit used as a parity bit.

The committee voted to use a seven-bit code to minimize costs associated with data transmission. Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.[3]:217, 236 §5 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.

Nothing seems to mandate that the 8th bit in a byte storing an ASCII character has to be 0. Therefore, when decoding ASCII characters, do we have to account for the possibility that the 8th bit may be set to 1? Python doesn't seem to take this into account — should it? Or are we guaranteed that the parity bit is always 0 (by some official standard)?

If the parity bit is 0 (default), then Python can decode a character ('@'):

When calculating UDP checksums I know that we complement the result and use it to check for errors. But I don't understand why we use 1's complement instead of 2's complement (as shown here). If there are no errors 1's complement results -1 (0xFFFF) and 2's complement results 0 (0x0000).

To check for correct transmission, receiver's CPU must first negate the result then look at the zero flag of ALU. Which costs 1 additional cycle for negation. If 2's complement was used the error checking would be done simply by looking at the zero flag.

I've tried couple of weeks and searched for days for an answer, but haven't found it. My code is rather large and intertwined, but my problem is with 3 functions/classes, therefore I will only show my declarations and relevant information. I have the following non-compliable code:

This Microsoft Docs article shows how to configure SignalR in a Blazor app. There's a step there that adds the response compression middleware for the application/octet-stream MIME type:

Please let me know. It is a sensor made by KEYENCE and is supposed to exchange ASCII. The specification states that, as an example, if you send such data, it will be received normally.

SR, 06,101 CRLF (ASCII) 0x53, 0x52, 0x2C, 0x30, 0x36, 0x2C, 0x31, 0x30, 0x31, 0x00, 0x0A (hexadecimal)

I created this example with python code and sent it. However, although the signal is being transmitted, an alarm is displayed and it seems that it is not being received normally. I wrote ASCII code transmission in python for the first time this time. Is there something wrong with the code? Thank you for your cooperation.

I'm a beginner in python so I have this program where it classifies tweets into different categories (sport,sante, culture...) using keywords and I would like to copy-paste every line of the JSON file that belongs to a certain category into a file named text1 and I did the following : but I guess I did it the wrong way since I keep receiving the same error please any suggestion on how to solve this problem!

I am trying to establish a method of estimating infectious disease parameters by comparing real epidemic curves with simulations of a stochastic SIR model. To construct the stochastic SIR model, I am using the deSolve package and instead of using fixed parameter values I would like to draw the parameter value used in the equations at each time point from a Poisson distribution centered on the original parameter values.

Using the parameter beta as an example, beta represents the average number of transmission events per capita and is the product of the average number of contacts and the probability that transmission occurs upon contact. Realistically, there is variation in the number of contacts a person will have and since transmission is also a probabilistic event there is variation surrounding this too. So even if the average transmission rate were to be 2.4 (for example), an individual can go on to infect 0, 1, 2 or 3 ... etc. people with varying probabilities.

I have tried to incorporate this into my code below using the rpois function and reassigning the parameters used in the equations to the outputs of the rpois.

I have run my code with the same initial values and parameters multiple times and all the curves are different indicating that SOMETHING "stochastic" is going on, but I am unsure whether the code is sampling using the rpois at each time point or just once at the beginning. I have only started coding very recently so do not have much experience.

I would be grateful if anyone more experienced than myself could verify what my code is ACTUALLY doing and whether it is sampling using rpois at each time point or not. If not I would be grateful for any suggestions for achieving this. Perhaps a loop is needed?

I am using tabula-py to read my class timetable PDF file in python and the return value 'data' has a lot of 'nan' values that I cannot seem to clean. Can someone suggest a solution? Should I be using something instead of tabula-py? I've attached a link to the picture of the PDF. I have redacted some info from the PDF for privacy.1

My code is as follows:

I was trying to do a car transmission type input validation, but why does it keep saying invalid input although I have entered the right input (M/A)?
