QUESTION
I tried upgrading Android Gradle Plugin from 4.2.2 to 7.0.1 using the upgrade assistant which is available in Android Studio at Tools > AGP Upgrade Assistant. The only change it made was to my project-level build.gradle file:
...ANSWER
Answered 2021-Aug-24 at 16:35the Android Gradle Plugin documentation still says classpath 'com.android.tools.build:gradle:4.2.0' instead of 7.0.1.
You need to read further down the page, to this and this. That table is only relevant for pre-7.0.0 versions.
Is this a bug in Android Gradle Plugin 7.0.1?
Quite possibly. Or, perhaps beyond, as the Instantiatable
Lint check has a history of problems.
If your scenario does not match one of those three August 2021 bugs, and you are in position to provide a reproducible test case, file a fresh issue! Beyond that, if a clean-and-rebuild is not clearing up your problem, you might need to simply disable the Instantiatable
Lint check for the time being by adding the following to all of your build.gradle files at the application or library level (i.e. all except your project-level build.gradle):

...ANSWER
Answered 2021-Sep-26 at 13:34Your issue is related to interoperability between TypeScript/ECMAScript modules and CommonJS.
When it comes to the differences between ECMAScript modules and CommonJS modules:
- CommonJS modules are meant to be imported like
const library = require('library')
which allows to retrieve the fullexports
object of that library. There is no notion of default import in CommonJS - ECMAScript modules have explicit
export
clauses for every exported item. They also feature a default import syntax which allows to retrieve thedefault
export in a local variable.
In order to implement interoperability between CommonJS modules and TypeScript's default import syntax, CommonJS modules can have a default
property.
That default
property can even be added automatically by TypeScript when esModuleInterop
is enabled (which also enables allowSyntheticDefaultImports
). This option adds this helper function at transpilation time:

Im attempting to find model performance metrics (F1 score, accuracy, recall) following this guide https://machinelearningmastery.com/how-to-calculate-precision-recall-f1-and-more-for-deep-learning-models/

Answered 2021-Dec-30 at 03:53There are a few ways to approach this but what I'd probably do – and a generally useful pattern – is to use a subset to create a slightly over-inclusive multi and then redispatch the case you shouldn't have included. For the example you provided, that might look a bit like:

Answered 2022-Jan-04 at 16:07To test a MRJAR the classes must be packaged as a jar, so don't use surefire with target/classes

And you must run it at least twice, once per targeted Java version.
I would write a unittest, that works for all Java versions, but might skip certain tests.
QUESTION
First, the question: is there a way to choose the platform (e.g. x86_64, AMD64, ARM64) for a GitHub Codespace?
Here's what I've found so far:
Attempt 1 (not working):
From within GitHub.com, you can choose the "machine" for a Codespace, but the only options are RAM and disk size.
Attempt 2 (EDIT: not working): devcontainer.json
When you create a Codespace, you can specify options by creating a top-level .devcontainer
folder with two files: devcontainer.json
and Dockerfile
Here you can customize runtimes, installed packages, etc., but the docs don't say anything about determining architecture...
...however, the VSCode docs for devcontainer.json
has a runArgs
option, which "accepts Docker CLI arguments"...
and the Docker CLI docs on --platform say you should be able to pass --platform linux/amd64
or --platform linux/arm64
, but...
When I tried this, the Codespace would just hang, never finishing building.
Attempt 3 (in progress): specify in Dockerfile
This route seems the most promising, but it's all new to me (containerization, codespaces, docker). It's possible that Attempts 2 and 3 work in conjunction with one another. At this point, though, there are too many new moving pieces, and I need outside help.
- Does GitHub Codespaces support this?
- Would you pass it in the Dockerfile or devcontainer.json? How?
- How would you verify this, anyway? [Solved:
dpkg --print-architecture
oruname -a
] - For Windows, presumably you'd need a license (I didn't see anything on GitHub about pre-licensed codespaces) -- but that might be out of scope for the question.

ANSWER
Answered 2021-Dec-17 at 21:44EDIT: December 2021
I received a response from GitHub support:
The VM hosts for Codespaces are only x86_64 and we do not offer any ARM64 machines.
So for now, setting the platform does nothing, or fails.
But if they end up supporting multiple platforms, you should be able to (in Dockerfile)
RUN --platform=arm64|amd64|x86-64 [image-name]
,
Which is working for me in the non-cloud version of Docker.
Original answer:
I may have answered my own question
In Dockerfile
:
I had RUN alpine
changed to
RUN --platform=linux/amd64 alpine
or
RUN --platform=linux/x86-64 alpine
checked at the command line with
uname -a
to print the architecture.
Still verifying, but seems promising. [EDIT: Nope]
So, despite the above, I can only get GitHub codespaces to run x86-64. Nevertheless, the above syntax seems correct.
A clue:
In the logs that appear while the codespace is building, I saw target OS: x86
Maybe GitHub just doesn't support other architectures yet. Still investigating.

I am using UITableView

QUESTION
In short:
I have implemented a simple (multi-key) hash table with buckets (containing several elements) that exactly fit a cacheline. Inserting into a cacheline bucket is very simple, and the critical part of the main loop.
I have implemented three versions that produce the same outcome and should behave the same.
The mystery
However, I'm seeing wild performance differences by a surprisingly large factor 3, despite all versions having the exact same cacheline access pattern and resulting in identical hash table data.
The best implementation insert_ok
suffers around a factor 3 slow down compared to insert_bad
& insert_alt
on my CPU (i7-7700HQ).
One variant insert_bad is a simple modification of insert_ok
that adds an extra unnecessary linear search within the cacheline to find the position to write to (which it already knows) and does not suffer this x3 slow down.
The exact same executable shows insert_ok
a factor 1.6 faster compared to insert_bad
& insert_alt
on other CPUs (AMD 5950X (Zen 3), Intel i7-11800H (Tiger Lake)).
ANSWER
Answered 2021-Oct-25 at 22:53The TLDR is that loads which miss all levels of the TLB (and so require a page walk) and which are separated by address unknown stores can't execute in parallel, i.e., the loads are serialized and the memory level parallelism (MLP) factor is capped at 1. Effectively, the stores fence the loads, much as lfence
would.
The slow version of your insert function results in this scenario, while the other two don't (the store address is known). For large region sizes the memory access pattern dominates, and the performance is almost directly related to the MLP: the fast versions can overlap load misses and get an MLP of about 3, resulting in a 3x speedup (and the narrower reproduction case we discuss below can show more than a 10x difference on Skylake).
The underlying reason seems to be that the Skylake processor tries to maintain page-table coherence, which is not required by the specification but can work around bugs in software.
The DetailsFor those who are interested, we'll dig into the details of what's going on.
I could reproduce the problem immediately on my Skylake i7-6700HQ machine, and by stripping out extraneous parts we can reduce the original hash insert benchmark to this simple loop, which exhibits the same issue:
QUESTION
I am using VSCode, and when I add the line 'react-hooks/exhaustive-deps': 'warn'
to my .eslintrc.js, I get the following in the ESLint output:
ANSWER
Answered 2021-Oct-15 at 00:55ESLint 8.0.0 comes with a breaking change for rules that provide suggestions. There is nothing you can put into your .eslintrc.js to make it work if you use rules that haven't been updated to work after this change.
What you can do:
- Use ESLint 7 until the plugin is updated to work with ESLint 8.
- In case of
eslint-plugin-react-hooks
, the offending rule has already been updated (check this line on GitHub), it's just that there hasn't been a stable release of the package since. However there have been daily alpha releases, at the time of writing the latest version is4.2.1-alpha-c3a19e5af-20211014
. If you really need both ESLint 8 and this plugin, you can use an alpha version until the next stable version comes out.
