Element disappearing before it is supposed to

Asked 2021-Jun-16 at 02:50

Recently I've been coding a clicker game and now have run into a problem with the onclick function. What I'm trying to do is on the first click, have it change into certain text, and on the second and third clicks change it to a different text. However, on the fourth click, I'd like it to disappear.

However, it disappears on the third click instead of the fourth click. The third click is supposed to show more text, and then call a function and vamoose. It just disappears. Here is my code:

I'm going to rewrite your code because it seems to be missing something.

In this code, I'm using a single event handler. Then using a counter and switch statement to determine the current click count.

Answered 2021-Jun-16 at 01:27

I don't know if I understood your question, but this is what the code is doing:

var_list is a list with two elements [100, 2025].

slice1 and slice2 are being defined as (var_list + [None]*2)[:2]. This expression adds the var_list to a new list of 2 None objects ([None] * 2 == [None, None]). The result of this expression ((var_list + [None] *2)) is the addition of these 2 lists, which is: [100, 2025, None, None]

Then the last part ([:2]) is just slicing the first 2 elements of this resulting list and assigning it to the variables. And since, in this case, the first 2 items are the var_list itself, it will assign the first element to slice1 and the second to slice2.

Aggregating all values not in the same group

Asked 2021-Jun-15 at 22:57

Is there a way in PostgreSQL to take this table:

ID country name values 1 USA John Smith {1,2,3} 2 USA Jane Smith {0,1,3} 3 USA Jane Doe {1,1,1} 4 USA John Doe {0,2,4}

and generate this table from it with the column agg_values:

ID country name values agg_values 1 USA John Smith {1,2,3} {0,1,3,1,1,1,0,2,4} 2 USA Jane Smith {0,1,3} {1,2,3,1,1,1,0,2,4} 3 USA Jane Doe {1,1,1} {1,2,3,0,1,3,0,2,4} 4 USA John Doe {0,2,4} {1,2,3,0,1,3,1,1,1}

Where each row aggregates all values except from the current row and its peers.
So if name = John Smith then agg_values = aggregate of all values where name not = John Smith. Is that possible?

You can use a lateral join to a derived table that unnests all rows where the name is not equal and then aggregates that back into an array:

QUESTION

Allocating memory with calloc for an int pointer

Asked 2021-Jun-15 at 21:19

Hey guys given the example below in C when operating on a 64bit system as i understand, a pointer is 8 byte. Wouldn't the calloc here allocate too little memory as it takes the sizeof(int) which is 4 bytes? Thing is, this still works. Does it overwrite the memory? Would love some clarity on this.

Bonus question: if i remove the type casting (int*) i sometimes get a warning "invalid conversion from 'void*' to 'int*', does this mean it still works considering the warning?

...

ANSWER

Answered 2021-Jun-15 at 21:19

calloc is allocating the amount of memory you asked for on the heap. The pointer is allocated by your compiler either in registers or on the stack. In this case, calloc is actually allocating enough memory for 4 ints on the heap (which on most systems is going to be 16 bytes, but for the arduino uno it would be 8 because the sizeof(int) is 2), then storing the pointer to that allocated memory in your register/stack location.

For the bonus question: Arduino uses C++ instead of C, and that means that it uses C++'s stronger type system. void * and int * are different types, so it's complaining. You should cast the return value of malloc when using C++.

How to use select() to set a timer for sockets?

Asked 2021-Jun-15 at 21:17

I'm currently using Winsock2 to be able to test a connection to multiple local telnet servers, but if the server connection fails, the default Winsock client takes forever to timeout.

I've seen from other posts that select() can set a timeout for the connection part, and that setsockopt() with timeval can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.

How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?

...

ANSWER

Answered 2021-Jun-15 at 21:17

select() can set a timeout for the connection part.

Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.

setsockopt() with timeval can timeout the receiving portion of the code

Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).

Try something like this:

@pRUKE=dfgt@pRECTYPE="SBEL", @pSBEL_EFF_DT="01/01/2017", @pCSPI_ID="JKOX0001", @pSBEL_FI="A"

After:

@pRUKE=dfgt@pRECTYPE="SMDR", @pCONFIG="Y" XXXXXXX

@pRUKE=dfgt@pRECTYPE="SBSB", @pGWID="1234", @pSBEL_MCTR_RSN="KX28", @pSBSB_9000_COLL=""

if after SBSB, if there is no SBEL, then that SBSB can be ignored.

what i did is egrep -n "pRECTYPE="SBSB"|pRECTYPE="SBEL"" filename | sed '$!N;/pRECTYPE="SBEL"/P;D' | awk -F: '{print $1}' | awk 'NR%2{printf "%s,",$0;next;}1' > 4.txt;

by this i will get the line number eg: 2,4 17,19

line 9 12 14 will be ignored

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.
