QUESTION
I can't figure how to set the value of a Series at a specific index in a chainable style.
For example, say I have the following dataframe:

to return a copy of the column with the item at the specified index.
This is basically like using .loc

QUESTION
I have been using the #[tokio::main]
macro in one of my programs. After importing main
and using it unqualified, I encountered an unexpected error.
ANSWER
Answered 2022-Feb-15 at 23:57#[main]
is an old, unstable attribute that was mostly removed from the language in 1.53.0. However, the removal missed one line, with the result you see: the attribute had no effect, but it could be used on stable Rust without an error, and conflicted with imported attributes named main
. This was a bug, not intended behaviour. It has been fixed as of nightly-2022-02-10
and 1.59.0-beta.8
. Your example with use tokio::main;
and #[main]
can now run without error.
Before it was removed, the unstable #[main]
was used to specify the entry point of a program. Alex Crichton described the behaviour of it and related attributes in a 2016 comment on GitHub:
Ah yes, we've got three entry points. I.. think this is how they work:
- First,
#[start]
, the receiver ofint argc
andchar **argv
. This is literally the symbolmain
(or what is called by that symbol generated in the compiler).- Next, there's
#[lang = "start"]
. If no#[start]
exists in the crate graph then the compiler generates amain
function that calls this. This functions receives argc/argv along with a third argument that is a function pointer to the#[main]
function (defined below). Importantly,#[lang = "start"]
can be located in a library. For example it's located in the standard library (libstd).- Finally,
#[main]
, the main function for an executable. This is passed no arguments and is called by#[lang = "start"]
(if it decides to). The standard library uses this to initialize itself and then call the Rust program. This, if not specified, defaults tofn main
at the top.So to answer your question, this isn't the same as
#[start]
. To answer your other (possibly not yet asked) question, yes we have too many entry points.
QUESTION
I see multiple sources claiming that an exception happening inside an async{} block is not delivered anywhere and only stored in the Deferred
instance. The claim is that the exception remains "hidden" and only influences things outside at the moment where one will call await()
. This is often described as one of the main differences between launch{}
and async{}
. Here is an example.
An uncaught exception inside the async code is stored inside the resulting Deferred and is not delivered anywhere else, it will get silently dropped unless processed
According to this claim, at least the way I understand it, the following code should not throw, since no-one is calling await:
...ANSWER
Answered 2022-Jan-29 at 10:51In some sense, the mess you experience is a consequence of Kotlin coroutines having been an early success, before they became stable. In their experimental days, one thing they lacked was structured concurrency, and a ton of web material got written about them in that state (such as your link 1 from 2017). Some of the then-valid preconceptions remained with people even after their maturation, and got perpetuated in even more recent posts.
The actual situation is quite clear — all you have to understand is coroutine hierarchy, which is mediated through the Job
objects. It doesn't matter whether it's a launch
or an async
, or any further coroutine builder — they all behave uniformly.
With this in mind, let's go through your examples:
QUESTION
I have that PyCharm is halting on all my exceptions, even the ones I am handling in a try except
block. I do not want it to break there - I am handling and perhaps expecting an error. But every other exception I do want it to halt and suspend execution (e.g. so that I have the program state and debug it).
How does one do that?
I tried going into the python exception breakpoint option but I didn't see an option like "break only on unhandled exceptions" e.g as suggested by these:
- Stop PyCharm If Error
- https://intellij-support.jetbrains.com/hc/en-us/community/posts/206601165-How-to-enable-stopping-on-unhandled-exceptions-
note this is my current state, note how it stopped in my try block... :(

QUESTION
This only applies to Visual Studio 2022. I had uninstalled VS2019 and Preview where F# worked absolutely fine (F# 5.0). I am using VS2022 to use F# 6.0 and do not want to go back to F# 5.0.
The issue is specific to F#. I also use C# and I have no issues running the latest C# under VS2022.
There are near continual DevEnv processes running consuming anywhere from 1 to 4 of my CPU's 4 Hyperthreads. I have switched off all experimental options I can find in F# settings.
Sometimes there are 2 or more background processes running , sometimes paused and sometimes none - there appears to be no correlation between this and the background CPU consumption
Sometimes I have a pop up Dialog about waiting to complete an editor process or a compile process.
When devenev.exe is consuming CPU cycles under the properties I see there is always one clr.dllCoUnInitializeEE+0x6790
that is the culprit. I though this was meant to be a short-lived process? Sometimes there are two or three of these consuming most of a HyperThread (There are identical others but with very low or no CPU consumption). The stack on the guilty thread is as follows:

for now, there is only one option: use visual studio 2019. or try finding alternatives. there should be somewhere around the net

QUESTION
Please could someone shed some light into the issues I'm having with Webpack. I've not used Webpack for fonts before and have run into a bit of a headache I've not been able to solve. I'm pulling the fonts from a .css file using url().
What I'm getting after Webpack has done its thing is 3 .woff files with their names changed to a hash like name. I then have a fonts folder with the 3 fonts in named correctly. Looking at the main.css (the one Webpack produced) the url() is now looking at the font files with the hash names. When I open the hash named .woff files its an export command pointing to the fonts folder and to the correct font.... Is this how it meant to work?
When I load up the webpack in the console I have errors for each file: Failed to decode downloaded font: http://localhost/OPM/wpcontent/themes/theme/assets/build/b4f8bd69b3d37cc51e2b.woff OTS parsing error: invalid sfntVersion: 1702391919
This is wants in the .woff file
export default __webpack_public_path__ + "fonts/font-icons.woff";
