QUESTION
I have a List
that contains entity Timeslot
with the following fields:
timeslot_id
;day
;start_time
;end_time
.
For example, this list contains two records:
start_time
of the first record equals9:00
andend_time
equals10:00
.start_time
of second object equals10:00
andend_time
equals11:00
.
And the second list contains timestamps List
:
ANSWER
Answered 2022-Apr-16 at 20:05I've simplified your Timeslot
class for this problem (for demonstration purposes) since for this task you primarily concern about the start time and end time of each timeslot.
My approach is to create a set of LocalDateTime
objects by extracting the start time from each timeslot that is already taken (represented by your first list).
Then create a stream over the query
list and filter the date-time object that are not present in the set. Then create a timeslot using each date-time object as a start time (end time = start time + 1 hour). And collect all the stream elements into a list.
Note: terminal operation toList()
creates an immutable list, you can obtain a mutable list by applying collect(Collectors.toList())
instead.

Recently I face an issues to install my dependencies using latest Node and NPM on my MacBook Air M1 machine. Then I found out M1 is not supported latest Node version. So my solution, to using NVM and change them to Node v14.16
Everything works well, but when our team apply new eslint configuration. Yet, I still not sure whether eslint was causes the error or not.
.eslintrc ...ANSWER
Answered 2022-Mar-17 at 00:11I had a similar problem with another module.
The solution I found was to update both node (to v16) and npm (to v8).
For Node, I used brew (but nvm should be OK).
For npm, I used what the official doc says :
npm install -g npm@latest

Answered 2021-Nov-22 at 07:03Found this issue, pytube v11.0.1. It's a little late for me, but if no one has submitted a fix tomorrow I'll check it out.
in C:\Python38\lib\site-packages\pytube\parser.py
Change this line:
152: func_regex = re.compile(r"function\([^)]+\)")
to this:
152: func_regex = re.compile(r"function\([^)]?\)")
The issue is that the regex expects a function with an argument, but I guess youtube added some src that includes non-paramterized functions.

We have a bunch of microservices based on Spring Boot 2.5.4 also including spring-kafka:2.7.6
and spring-boot-actuator:2.5.4
. All the services use Tomcat as servlet container and graceful shutdown enabled. These microservices are containerized using docker.
Due to a misconfiguration, yesterday we faced a problem on one of these containers because it took a port already bound from another one.

QUESTION
I'm trying to build a factorization algorithm using react. I would like to add results
to LocalStorage
based on results from factorization. However, LocalStorage
sets previous results not current ones.
I think this is happening because useEffect
runs on every new [number]
(=user input) and not based on [results]
. However, I need useEffect
to run on new user input submition because that's when factorization has to be triggered.
How could I make localStorage
set correct results after that factorization has completed (on the finally
block if possible) ?

QUESTION
Today I was using a stream that was performing a parallel()
operation after a map, however; the underlying source is an iterator which is not thread safe which is similar to the BufferedReader.lines implementation.
I originally thought that trySplit would be called on the created thread, however; I observed that the accesses to the iterator have come from multiple threads.
By example, the following silly iterator implementation is just setup with enough elements to cause splitting and also keeps track of the unique threads that accessed the hasNext
method.
ANSWER
Answered 2021-Dec-13 at 17:33Thread safety does not necessarily imply being accessed by only one thread. The important aspect is that there is no concurrent access, i.e. no access by more than one thread at the same time. If the access by different threads is temporally ordered and this ordering also ensures the necessary memory visibility, which is the responsibility of the caller, it still is a thread safe usage.
The Spliterator
documentation says:
Despite their obvious utility in parallel algorithms, spliterators are not expected to be thread-safe; instead, implementations of parallel algorithms using spliterators should ensure that the spliterator is only used by one thread at a time. This is generally easy to attain via serial thread-confinement, which often is a natural consequence of typical parallel algorithms that work by recursive decomposition.
The spliterator doesn’t need to be confined to the same thread throughout its lifetime, but there should be a clear handover at the caller’s side ensuring that the old thread stops using it before the new thread starts using it.
But the important takeaway is, the spliterator doesn’t need to be thread safe, hence, the iterator wrapped by a spliterator also doesn’t need to be thread safe.
Note that a typical behavior is splitting and handing over before starting traversal, but since an ordinary Iterator
doesn’t support splitting, the wrapping spliterator has to iterate and buffer elements to implement splitting. Therefore, the Iterator
experiences traversal by different threads (but one at a time) when the traversal has not been started from the Stream
implementation’s perspective.
That said, the lines()
implementation of BufferedReader
is a bad example which you should not follow. Since it’s centered around a single readLine()
call, it would be natural to implement Spliterator
directly instead of implementing a more complicated Iterator
and have it wrapped via spliteratorUnknownSize(…)
.
Since your example is likewise centered around a single poll()
call, it’s also straight-forward to implement Spliterator
directly:

Install streams
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
