QUESTION
I'd like to update values in a column ['D'] of my data frame based on the substrings contained in column ['A']
I have dataframe df, where column D is an exact copy of column A. Column A has list of different cereal names. But I want to check if A contains a certain word and if so, then column D updates to show that word.
For example, If A contains the word Bran then D should update to show Bran. And if column A contains none of the criteria we are looking for then it should return Other.

QUESTION
This is doing my nut in!
Simply updating VS 2022 to ver. 17.1.0 has broken the ability to drag the header of a floating window towards the header of another window and allow them to merge into one single floating window with a tabbed view layout.
This has ruined my productivity in being able to have multiple files open between a multi monitor layout. Is anyone aware of a option/setting that might have been disabled from the update?
The screenshot below shows where I would usually drag one floating window towards another an if i left go of the mouse in the right place, the two windows would usually snap tpgather into one window with multiple tabs:
Edit: Futher observations conclude the latest VS 17.1.0 have changed the way we can group floating windows together.
By default, my tabs are configured to display along the top, however the only way i can group together the windows is if i change the tab location from the TOP to the Side, but this changes the tab layout in the main IDE as well as floating windows, so it screws eveything up.
Merging the windows together:
Incidentally if I revert back to displaying the Tabs at the TOP, then we have the affect i wanted BUT I stil cannot merge any further windows in that mode:
...ANSWER
Answered 2022-Mar-05 at 13:14Its just occured to me that the you can snap together the floating windows into a tabbed view by dragging one window with the mouse over the top of another window and then you see the following icon appear:
If you then drag the window and move your mouse cursor over the center point of this icon set then it will in fact merge the two windows together into a tabbed view.
Well this wanst the most intelligent question I'd ever asked! I just hadnt done it this way before and the previous way in doing this had stopped working foo me since upgrading VS22 to latest 17.1.0 from 17.0.1

I'm processing some very big files, and my simple Go program to do this is taking 2 minutes to run instead of the 15 seconds it takes for the equivalent C program (https://gist.github.com/g2boojum/5729bf75a41f537b8251af25a816c2fc). Clearly I'm missing something important. (It's also my first Go program, so I'm sure the code is idiomatically poor, too.)
The files I'm processing are csv files, which look like the following, and the only issue is that they're GB in size.

QUESTION
I am new in Git and I have used git pull origin in most of the time to get the changes from remote repository.
However, as I get some experience, I have observed that git fetch is preferred more, but reading several topics e.g. What is the difference between 'git pull' and 'git fetch'? and Git: Fetch and merge, don’t pull, now I am confused and need a clarification if there is a valid reason to prefer it except from checking changes before getting them.
The general idea behind this,
git pullisgit fetch+git merge, nut of course there are several drawbacks, etc.
So, could you please clarify me on:
1. How I should update my local branch from remote?
2. As far as I see, the difference between git pull origin and git pull origin, the latter gets all the branches from origin besides . Is that true? And which one should I prefer?
ANSWER
Answered 2022-Jan-25 at 07:27I am not Writing it based on document but based on some experience. its not much but it might help.
- Git pull is the command you should use to get the code in remote to your local.
- git fetch only get the meta data not the actual code.
In general with single repo you will never encounter fetch command being used, but if you are working on fork or have multiple remote repo, then only fetch is useful or being used frequently.
QUESTION
... and it's driving me nuts trying to understand what I'm doing wrong!
Playground: https://go.dev/play/p/ZQP8Y-gwihQ
The example looks contrived but it's drawn from code that I have where the error arose. In my code I'm hashing the bytes buffer and want the process to be predictable.
...ANSWER
Answered 2021-Dec-25 at 10:08What you're missing is that the stream of bytes produced by an Encoder instance has global (program-wide) state in addition to the per-Encoder state. That global state consists of [note: edited phrase here] registered-and-sent types.
When you send a typed value, if the type has not yet been registered before being sent, it will be registered for you, in the global state. This assigns an internal numeric value to the type. See Register (and its companion RegisterName). When you call your X, that registers the anonymous struct type that holds s in X. When you call your Y, that registers the anonymous struct type that holds s in Y. These get different internal type numbers. By not calling X, that type is never registered, and Y's type gets registered under the first available number.
In my code I'm hashing the bytes buffer ...
That's not a great idea for what are now probably obvious reasons. However, if you explicitly register each type in a known order, you'll be safe enough here unless some future version changes the wire format for some (presumably good) reason. Oops, testing this shows it doesn't help either. That's because even if the type is registered, it doesn't have a transmit number set until the first time a value of that type gets encoded. So you need to encode (and optionally then just discard) a value of each type.
Here is a functioning example of carefully discard-encoding the two types, so that commenting out the call to log.Println(a.X()) has no effect on the encoding of the second value.
