How do I make invalidate an entry and return its value from a Caffeine Cache?

I'm trying to remove an entry from the Caffeine cache manually. I have two attempts but I suspect that there are some problems with both of them:

This one seems like it could suffer from a race condition.

You should use cache.asMap().remove(key) as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.

The Cache interface is opinionated for how one should commonly use a cache, while the asMap() view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.

Two options. The first will use coalesce() to eliminate the null values. The second will create a a unique set of intersections via a CROSS JOIN and a UNION ALL (brute force)

I need to strip all the symbols from a string in order to create an `IEqualityComparer` that ignores punctuation symbols

Asked 2021-Jun-15 at 23:05

In part of my application I have an option that displays a list of albums by the current artist that aren't in the music library. To get this I call a music API to get the list of all albums by that artist and then I remove the albums that are in the current library.

To cope with the different casing of names and the possibility of missing (or extra punctuation) in the title I have written an IEqualityComparer to use in the .Except call:

If you're going to use the CompareOptions enum, I feel like you might as well use it with the CompareInfo class that it's documented as being designed for:

Defines the string comparison options to use with CompareInfo.

Then you can just use the GetHashCode(string, CompareOptions) method from that class (and even the Compare(string, string, CompareOptions) method if you like).

Error when converting string to integer when values are numbers in Pandas data frame

Asked 2021-Jun-15 at 23:03

I have a column with the datatype 'object', but it actually contains numbers (408, 415, 510) with no missing values. I want to convert this to integer with the code below, but I get the error: invalid literal for int() with base 10: 'A415' (I added the first line of code after reading other posts, but I get the same error even if I drop the first line of code).

...

ANSWER

Answered 2021-Jun-15 at 23:03

Looks like there is a "A415" value in your column. Could be a typo?

You can check if this is the case by getting a list of the unique values in this pandas column, like below. This is a quick way of knowing if all values look alright.

Because you can't have braces in that context. If you look at cppreference on list initialization, you see that the case inside a ternary operator isn't defined. So it can't be parsed correctly and you get the error you have.

You'd have to use something like this :

QUESTION

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.

QUESTION

Div with absolute width is smaller than specified

Asked 2021-Jun-15 at 20:37

I am trying to have a number of columns with exact widths, and their heights split evenly between some number of elements. For some reason, despite my indicating an exact 200px width on each column, they are instead getting a computed width of 162px somehow. Chrome dev tools is showing some weird arrow thing indicating that it it was shrunk from it's intended size for some reason. I've even tried removing all of the content from the div's as possible so as to rule out some weird interaction with the size of children.

The html for the relevant area is this:

ANSWER

Answered 2021-Jun-15 at 20:20

Setting display: flex turns the sizing of child elements over to the flex container. If you don't want the individual elements to resize, set flex-grow: 0, flex-shrink: 0, and flex-basis: 200px. You can do all three using the flex shorthand:
