kandi X-RAY | LOST Summary

LOST is a R library typically used in Analytics applications. LOST has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is an introduction to the technique. Most of the time this will be just a few sentences about what it is and does, and perhaps why it is used. However, in cases of more niche or complex material, there may be a reason to include more detailed information or general non-language-specific instructions here. In general, however, for more detailed explanations or discussions of statistical properties, you can always just link to an outside trusted source like Wikipedia or a (non-paywalled) academic paper. Math is not supported. Generally, you can refer to terms by simply putting them in bold. If an equation is necessary, create the equation as an image on this page and include the equation as an image.

Xarray (from grib file) to dataset

Asked 2021-Jun-16 at 02:36

I have a grib file containing monthly precipitation and temperature from 1989 to 2018 (extracted from ERA5-Land).

I need to have those data in a dataset format with 6 column : longitude, latitude, ID of the cell/point in the grib file, date, temperature and precipitation.

I first imported the file using cfgrib. Here is what contains the xdata list after importation:

QUESTION

Postgres: Count multiple events for distinct dates

Asked 2021-Jun-15 at 17:04

People of Stack Overflow!

Thanks for taking the time to read this question. What I am trying to accomplish is to pivot some data all from just one table. The original table has multiple datetime entries of specific events (e.g. when the customer was added add_time and when the customer was lost lost_time). This is one part of two rows of the deals table:

id add_time last_mail_time lost_time 5 2020-03-24 09:29:24 2020-04-03 13:20:29 NULL 310 2020-03-24 09:29:24 NULL 2020-04-03 13:20:29

I want to create a view of this table. A view that has one row for each distinct date and counts the number of events at this specific time.

This is the goal (times do not match with the example!):

I have working code, like this:

QUESTION

How to look up data in a separate dataframe (df2) based on date in df1 falling between date range values across two columns in df2

Asked 2021-Jun-15 at 16:38

Situation: I have two dataframes df1 and df2, where df1 has a datetime index based on days, and df2 has two date columns 'wk start' and 'wk end' that are weekly ranges as well as one data column 'statistic' that stores data corresponding to the week range.

What I would like to do: Add to df1 a column for 'statistic' whereby I lookup each date (on a daily basis, i.e. each row) and try to find the corresponding 'statistic' depending on the week that this date falls into.

I believe the answer would require merging df2 into df1 but I'm lost as to how to proceed after that.

Appreciate any help you might provide! Thanks!

df1: (note: I skipped the rows between 2019-06-12 and 2019-06-16 to keep the example short.)

age date 2019-06-10 20 2019-06-11 21 2019-06-17 19 2019-06-18 18

df2:

wk start wk end statistic 2019-06-10 2019-06-14 102 2019-06-17 2019-06-21 100 2019-06-24 2019-06-28 547 2019-07-02 2019-07-25 268

Desired output:

age statistic date :--- :-------- 2019-06-10 20 102 2019-06-11 21 102 2019-06-17 19 100 2019-06-18 18 100

Python Flask Import file could not be resolved

I'm trying to import 'greek' to 'api' file in same directory

This is my directory

...

ANSWER

Answered 2021-Jun-15 at 16:13

If the parent folder is api and a child is greek, then what you need is

An __init__.py file in the api folder
Then you can do from api import greek or from api.greek import *

Updating my response since original post has been updated and a directory structure (different from earlier post) provided

Based on your updated directory structure, I do not believe you need the __init___.py.
It seems you need a function or class called alphabet which is in greek.py. You should just do import greek and then to use alphabet, you do greek.alphabet

Losing messages when using RabbitMQ with .NET Core WebAPI

I am trying to receive and send simple messages from two web APIs using RabbitMQ. It is a pretty simple code for now, and I am trying to see if both the APIs are properly able to communicate with each other.

Java List removing items without any action

I'm facing a weird behavior in my Java code using List.

Here is the code :

ANSWER

Answered 2021-Jun-15 at 09:28

Your method getCommentsListProcessedManually modifies the list you're passing. I believe you're operating under the assumption that passing the list as a parameter somehow creates a copy of the list, whereas what is actually happening is that a reference to the list is passed by value.

There are several ways to solve this, but the easiest is to simply create a copy of your input list at the start of your method:

How in WebFlux to stop publisher when request is aborted by client?

Asked 2021-Jun-15 at 09:06

SpringBoot v2.5.1

There is an endpoint requesting a long running process result and it is created somehow
(for simplicity it is Mono.fromCallable( ... long running ... ).

Client make a request and triggers the publisher to do the work, but after several seconds client aborts the request (i.e. connection is lost). And the process still continues to utilize resources for computation of a result to throw away.

What is a mechanism of notifying Project Reactor's event loop about unnecessary work in progress that should be cancelled?

...

ANSWER

Answered 2021-Jun-15 at 09:06

fromCallable doesn't shield you from blocking computation inside the Callable, which your example demonstrates.

The primary mean of cancellation in Reactive Streams is the cancel() signal propagated from downstream via the Subscription.

Even with that, the fundamental requirement of avoiding blocking code inside reactive code still holds, because if the operators are simple enough (ie. synchronous), a blocking step could even prevent the propagation of the cancel() signal...

A way to adapt non-reactive code while still getting notified about cancellation is Mono.create: it exposes a MonoSink (via a Consumer) which can be used to push elements to downstream, and at the same time it has a onCancel handler.

You would need to rewrite your code to eg. check an AtomicBoolean on each iteration of the loop, and have that AtomicBoolean flipped in the sink's onCancel handler:

How to remove VIM as my Mac editor vs sublime

Asked 2021-Jun-15 at 06:57

How to remove VIM (completely) and change my mac command line editor to sublime?

I've spent the last three hours reading the same links on "how to remove VIM" only to get "how to remove MacVIM and reinstall it fresh" Or "How to remove Vim so I can reinstall it on Ubuntu"

My old laptop was fortunate to have a friend remove it but my new machine still has it installed.

I wish VIM would die in ~~"words redacted to excessive profanity"~~ dumpster fire while a hobo ~~"words redacted to excessive profanity"~~ to put out the fire

I've lost way too many hours trying to learn that outdated neckbeard elvish piece of UX trash so I want it gone. No, I'm not touching emacs.

Please tell me there is a way I can switch to sublime or am I permanently cursed to have this confusing black screen of death pop up when I try to git push or git tag stuff?

My original goal was to tag a git and push it but vim comes up and I can't figure out how to speak elvish.

I've been using PyCharm for a few years and love the interface but I need to dig deeper and a TDD Django book for class uses the terminal, it wants me to git -a "comments" so I need your advice.

So now I can't learn TDD Django because vim, MacVim and eMacs users flood the internet but I can't remove it nor figure out how to work it.

I've tried brew uninstall macvim which doesn't work because I have vim not macvim

I also tried sudo uninstall vim no luck as this is zsh mac not ubuntu

I tried brew uninstall vim to get No available formula or cask with the name "vim"

I've searched SO five times and keep getting the same links. Alternates I've tried brew uninstall ruby vim

per this post https://superuser.com/questions/1096438/brew-upgrade-broke-vim-on-os-x-dyld-library-not-loaded I tried, no luck.

You don't have to remove Vim from your machine. Instead, tell your system and your tools to use Sublime Text as default editor. After you have followed that tutorial, which I must point out is part of Sublime Text's documentation, you should have a system-wide subl command that you can use instead of vim. For that, you need to add those lines to your shell configuration file:

Does memory allocated on the stack get cleared out when freed?

...

ANSWER

Answered 2021-Jun-14 at 21:35

But is it set to zero?

No / maybe. There are no guarantees about the "value" of unallocated memory. Nor is there any way guaranteed by the standard to observe that hypothetical "value".

From an information security perspective: If you store private information in an object, then you should assume that the information may persist even after the storage duration of the object. And that an attacker may be able to access that information if your program is vulnerable to an exploit (typically, through undefined behaviour).
