The n2 - n1 in the case of a negative number as a result when converted to bool will yield true. So n1 turns out to be less than n2. That's why it is a bad practice to use ints in such Boolean context.

Yes, as stated in the documentation:

...comparison function object which returns true if the first argument is less than the second

But the implementation of the comparison here leads to failure. Try this and see for yourself:

Is there a Vim plugin that would TAB-complete symbols from CTags index?

Asked 2021-Jun-16 at 01:15

I've stumbled upon a quite innovative functionality in editor – ability to TAB-complete symbols from CTags index, on this Asciinema video.

I wonder if there is anything like it available for Vim? I've been using many completion engines like eg. CoC, however none of them seems to offer what NeoMCEdit does. Is there such plugin for Vim?

Basic keyword completion, :help i_ctrl-p/:help i_ctrl-n, already does that out of the box because of the default value of :help 'complete'.

Alternatively, you can use your tags files as exclusive source with :help i_ctrl-x_ctrl-].

The difference in behaviour can be accounted for by this behaviour, described in (for instance) the following note in ECMAScript 2022 Language Specification sect 14.3.2.1:

NOTE: If a VariableDeclaration is nested within a with statement and the BindingIdentifier in the VariableDeclaration is the same as a property name of the binding object of the with statement's object Environment Record, then step 5 will assign value to the property instead of assigning to the VariableEnvironment binding of the Identifier.

In the first case:

How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

Magnification Windows API - How to add Smoothing/Anti Aliasing

Asked 2021-Jun-15 at 20:44

Context

Since Windows 10 version 2004 update, the Magnifier windows application was updated. And as with every update, there are some issues with it.

Since those issues might take a long time to fix, I've decided to implement my own small project full screen magnifier.

I've been developing in c#, .Net 4.6 using the Magnification API from windows magnification.dll . All went good and well, and the main functionality is now implemented. One thing is missing though, a smoothing Mode for pixelated content... Windows Magnifier implements an anti aliasing/ smoothing to the Zoomed in content.

I've checked and the Magnification API, doesn't seem to provide that option.

how do i add smoothing mode to magnifier on windows magnification API?

I'm aware of pixel smoothing methods, but not familiar with win32 API to know where to hook the smoothing method to, before the screen refreshes.

EDIT:

Thanks to @IInspectable answer, after a small search i found this call to the Magnification API in a python project.

Based on that, I wrote this snippet in my C# application , and it works as intended!

...

ANSWER

Answered 2021-Jun-15 at 17:03

There is no public interface in the Magnification API that allows clients to apply filtering (other than color transforms). This used to be possible, but the MagSetImageScalingCallback API was deprecated in Windows 7:

This function works only when Desktop Window Manager (DWM) is off.

Even if it is still available, it will no longer work as designed. From Desktop Window Manager is always on:

In Windows 8, Desktop Window Manager (DWM) is always ON and cannot be disabled by end users and apps.

With that, you're pretty much out of luck trying to replicate the results of the Magnifier application's upscaler using the Magnification API.

The Magnifier application appears to be using undocumented API calls to accomplish the upscaling effects. Running dumpbin /IMPORTS magnify.exe | findstr "Mag" lists some of the public APIs, as well as the following:

MagSetLensUseBitmapSmoothing
MagSetFullscreenUseBitmapSmoothing

Unless you are willing to reverse-engineer those API calls, you're going to have to spend your time on another project, or look into a different solution.

A note on the upscaling algorithm: If you look closely you'll notice that the upscaled image doesn't exhibit any of the artifacts associated with smoothing algorithms.

The image isn't blurred in any way. Instead, it shows sharp edges everywhere. I don't know what upscaling algorithm is at work here. Wikipedia's entry on Pixel-art scaling algorithms lists some that have very similar properties. It might well be one of those, or a modified version thereof.

Yes, React refs need to be forwarded when using functional components.
You can't use the useRef hook within the loop.
