stamps | Course materials for STAMPS @ MBL

One thing which I have learnt from working with Identity Server is that, out of the box, ASP.NET Core Identity does not play too well with Identity Server. Refer to this question.

ASP.NET Identity contains a way of ejecting users where a particular user's data has changed. This is regulated by the SecurityStamp column of the aspnetuser table. When the stamp changes, the next time the cookie is validated, it fails validation.

This is turned on by default and it is the reason why it does not work well with Identity Server.
You end up with users getting kicked out erratically. And when you expect it to kick users out, it doesn't.

Anyhow, how do you disable this feature of ASP.NET Identity???

There is a column on the UserManager called SupportsUserSecurityStamp. However, it is a "getter" only and I cannot find any configuration setting for switching that to return false.

It seems to me that the only way is to derive from the UserManager class and make that property only ever return false.

That feels like a hack. Especially when you look at the code for that property on Github:

I'm trying to create a regex expression for use with Notepad++ to look for a specific character anywhere in the line but not capture it while still capturing what I want to find later in the string.

A sample of what I'm looking at is this:

The format of the .csv file is as below it has gaps in between as it gets data in packets. I want to plot the data with timestamp on the x-axis and sensor1 on the y-axis using matplotlib in python so is there a possibility.

This is the data in the CSV file so you can see 4 data points received 4 times this is being read at different time stamps. I tried approaching the normal way but it shows a blank plot.

This is the link to the CSV file. https://docs.google.com/spreadsheets/d/17SIabIYYmSogOdeYTzpEwy9s2pZuVO3ghoChSSgGwAg/edit?usp=sharing

thanks in advance.

I've been learning about how to use git and was very surprised to learn that you can change the timestamps of an old commit. It feels weird to me because I thought a big part of git was to ensure validity. That being, when you look back at commits, you know that what you see is what was done and when.

Consider this scenario: Someone uploads his local git project, which already has several commits in it, to GitHub. This person then adds another collaborator to this project. Can this collaborator tell if any of the time stamps on these existent commits have been edited?

So I'm accessing an Siemens LOGO! PLC to extract some data from. I managed to do that with my work partner but we're stuck on how the data is being saved. The data is being timestamped in a dictionary with the output and input bytes from the PLC. But the data comes in a certain order and is timestamped the moment the data is extracted.

Now the problem is that the timestamps and data isn't saved in the same order that the data comes in. Somewhere in the process it makes a mistake (I think), but we can't seem to find it.

I have a situation where I have a very large dataframe that has airplane location data with 5 rows per timestamp (see table below for an example of 1 timestamp... 3 of the rows just have dots but imagine they have plane_nums and locations)

First, I add a stamp to pdf files used iText7, about drawing's rev date... I get it. Second, if I update the drawings, need to update the stamp information, the simplest, to delete the stamp and add it again. But, I can't get the stamps in pdf.

I have a table which contains a column Start_Timestamp which has time stamp values like 2020-06-02 21:08:37. I would like to create new column which classifies these timestamps into bins of 6hours.

Eg.

Input :

Expected Output ( Here each bin is of 6hours width) :

I have tried using TIMESERIES but can anyone help to generate output in following format

I have been trying to externally log data to my home server with a little GSM modem and InfluxDB2 HTTP API- it is far away and needs to be external, just checking water levels and other system stuff.

I am struggeling to understand the correct payload and keys to give it in order for it to accept my data.

I am using an ESP32 and the requests module on Micro Python, using MicroPython_ESP32_psRAM_LoBo.

The GSM library I am using makes everything work as if I was connected to Wifi, I am pretty certian that my problem has nothing to do with the GSM side of things.

The system uses InfluxDB2 and Python3 ( Micro Python to be exact )
