30 Years of Linux

It is a fantastic moment to reflect that the Linux movement is 30 years old! On August 25, 1991, graduate student Linus Benedict Torvalds announced on the Usenet group comp.os.minix that he was working on "a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones.". The rest is history, and including Android, Linux now powers more than three billion active devices. It also has almost a 100% share of the Top500 supercomputers but lags in the desktop market with an under 4% share. Beyond the numbers, Linux today has been the poster-boy of the open source movement and has scaled open source as the most dominant software model. Multiple factors are contributing to the success. In my opinion, one of the most critical factors is the GPLV2 licensing model that enabled distribution and global innovation at scale. The kandi kit on 30 Years of Linux showcases popular Linux utilities selected by our users to celebrate the moment.

Loading a sound file in Pygame

Pygame is a Python package used to create games and multimedia applications. It is based on the SDL (Simple DirectMedia Layer) library, which gives low-level access to audio, keyboard, mouse, joystick, and graphics hardware through OpenGL and Direct3D. Python developers may easily design games and multimedia apps using Pygame's high-level methods and classes. It has modules for graphics, sound, input processing, event handling, and other aspects. Pygame is a cross-platform application that runs on Windows, macOS, Linux, and other platforms.

The Pygame module pygame.mixer offers features for loading, playing, and manipulating audio and music. It generates sound and music by utilizing the system's audio hardware.

A music file is loaded for playback into the Pygame mixer using the pygame.mixer.music.load(musicpath) function. The os module is not necessary for Pygame to load music. However, it is usually used to obtain the absolute path to the music file. The pygame.mixer.music.load() function in Pygame expects a string specifying the file path of the music file when loading it. Pygame may be unable to locate the file if you specify the filename or a relative path, especially if the code is executed from a separate directory. To avoid this problem, utilize the os.path module to obtain the music file's absolute path. The function os.path.abspath() accepts a path as input and returns an absolute path. No matter what the current working directory of the computer is, this guarantees that the music clip can be discovered and loaded.

Execution of Pygame.mixer

fig-1 Code snippet

fig-2 Output

Code

A music file is loaded for playback into the Pygame mixer using the pygame.mixer.music.load(musicpath) function. It doesn't return anything. If the file path is wrong or the file cannot be loaded for any other reason, an exception will be thrown.

The pygame.mixer.music.play() function can be used to play the loaded music file.

From the above output, We can understand that the mp3 file has been successfully loaded and thus no error has been thrown.

Import pygame and os by adding these statements as shown in the image above.
Initialise the pygame.mixer module using pygame.mixer.init() function.
Copy and paste the remaining code from the snippet mentioned.
Make sure to change the name of the file accordingly.
It is a better option to create a virtual environment while working with python.

Loading an image as a sprite in Pygame

A sprite is a two-dimensional image or animation integrated into a larger scene. It is an important concept in game programming used to create objects with a graphical representation. Loading an image as a sprite in Pygame means using an image file as a game entity. In Pygame, sprites are created using the pygame.sprite module. This module is used to manage and draw objects on the screen. It also provides a wide range of functions to manipulate and control sprites.

Sprite in Python is an object that represents an image on a computer screen. It can create games, interactive applications, and other graphical objects. Sprites can be created using the pygame library in Python.

Pygame is a cross-platform Python module designed to write video game codes. It contains computer graphics and sound libraries designed for the Python programming language. Pygame is highly portable and will run on nearly every platform and operating system.

Moving a sprite in response to keyboard events in PyGame

A sprite is an object in a Pygame program that can be moved around on the screen. A sprite typically consists of an image, a rect (position and size) and a list of associated attributes like velocity, acceleration, and behaviour. Sprites can represent characters, projectiles, scenery, or any other game element.

Moving a sprite in response to keyboard events is a form of game programming where the game responds to user input in key presses. When the user presses a certain key, the game will move the sprite in a predetermined direction. This allows for a more interactive gaming experience by allowing the user to control their character or other objects in the game.

Pygame is a set of Python modules designed for writing video games. It is open source and free to use, and it provides functionalities such as image handling and sound playback that can be used to create games in Python. Pygame is an easy way to start programming games, and it has been used to create many popular games.

Issue:

The issue raises after .NET 6 migration. There's a new feature that blocks multiple files from being copied to the same target directory with the same file name. See https://docs.microsoft.com/en-us/dotnet/core/compatibility/sdk/6.0/duplicate-files-in-output

Solution #1 (workaround):

You can add the following build property to all your publishable (*.Web) projects' *.csproj files. This property will bypass this check and works as previously, in .NET5.

1C:\Program Files\dotnet\sdk\6.0.100-rc.1.21458.32\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.ConflictResolution.targets(112,5): error NETSDK1152: Found multiple publish output files with the same relative path:

Solution #2:

Exclude the problematic files to be copied to the output folder. In this example we'll exclude these files: compilerconfig.json and package.json.

Add the following lines to your common.props (located in the root directory of your solution):

I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.

QUESTION

What's the mathematical reason behind Python choosing to round integer division toward negative infinity?

Asked 2022-Jan-30 at 01:29

I know Python // rounds towards negative infinity and in C++ / is truncating, rounding towards 0.

And here's what I know so far:

1               |remainder|
2-12 / 10  = -1,   - 2      // C++
3-12 // 10 = -2,   + 8      # Python
4
512 / -10  = -1,     2      // C++
612 // -10 = -2,   - 8      # Python
7
812 / 10  = 1,      2       // Both
912 // 10 = 1,      2
10
11-12 / -10 = 1,    - 2      // Both
12          = 2,    + 8
13
14C++:
151. m%(-n) == m%n
162. -m%n == -(m%n)
173. (m/n)*n + m%n == m
18
19Python:
201. m%(-n) == -8 == -(-m%n)
212. (m//n)*n + m%n == m
22

But why Python // choose to round towards negative infinity? I didn't find any resources explain that, but only find and hear people say vaguely: "for mathematics reasons".

For example, in Why is -1/2 evaluated to 0 in C++, but -1 in Python?:

People dealing with these things in the abstract tend to feel that rounding toward negative infinity makes more sense (that means it's compatible with the modulo function as defined in mathematics, rather than % having a somewhat funny meaning).

But I don't see C++ 's / not being compatible with the modulo function. In C++, (m/n)*n + m%n == m also applies.

So what's the (mathematical) reason behind Python choosing rounding towards negative infinity?

ANSWER

Answered 2022-Jan-18 at 21:46

Although I can't provide a formal definition of why/how the rounding modes were chosen as they were, the citation about compatibility with the % operator, which you have included, does make sense when you consider that % is not quite the same thing in C++ and Python.

In C++, it is the remainder operator, whereas, in Python, it is the modulus operator – and, when the two operands have different signs, these aren't necessarily the same thing. There are some fine explanations of the difference between these operators in the answers to: What's the difference between “mod” and “remainder”?

Now, considering this difference, the rounding (truncation) modes for integer division have to be as they are in the two languages, to ensure that the relationship you quoted, (m/n)*n + m%n == m, remains valid.

Here are two short programs that demonstrate this in action (please forgive my somewhat naïve Python code – I'm a beginner in that language):

C++:

1               |remainder|
2-12 / 10  = -1,   - 2      // C++
3-12 // 10 = -2,   + 8      # Python
4
512 / -10  = -1,     2      // C++
612 // -10 = -2,   - 8      # Python
7
812 / 10  = 1,      2       // Both
912 // 10 = 1,      2
10
11-12 / -10 = 1,    - 2      // Both
12          = 2,    + 8
13
14C++:
151. m%(-n) == m%n
162. -m%n == -(m%n)
173. (m/n)*n + m%n == m
18
19Python:
201. m%(-n) == -8 == -(-m%n)
212. (m//n)*n + m%n == m
22#include &lt;iostream&gt;
23
24int main()
25{
26    int dividend, divisor, quotient, remainder, check;
27    std::cout &lt;&lt; &quot;Enter Dividend: &quot;;                        // -27
28    std::cin &gt;&gt; dividend;
29    std::cout &lt;&lt; &quot;Enter Divisor: &quot;;                         // 4
30    std::cin &gt;&gt; divisor;
31
32    quotient = dividend / divisor;
33    std::cout &lt;&lt; &quot;Quotient = &quot; &lt;&lt; quotient &lt;&lt; std::endl;    // -6
34    remainder = dividend % divisor;
35    std::cout &lt;&lt; &quot;Remainder = &quot; &lt;&lt; remainder &lt;&lt; std::endl;  // -3
36
37    check = quotient * divisor + remainder;
38    std::cout &lt;&lt; &quot;Check = &quot; &lt;&lt; check &lt;&lt; std::endl;          // -27
39    return 0;
40}

Python:

1               |remainder|
2-12 / 10  = -1,   - 2      // C++
3-12 // 10 = -2,   + 8      # Python
4
512 / -10  = -1,     2      // C++
612 // -10 = -2,   - 8      # Python
7
812 / 10  = 1,      2       // Both
912 // 10 = 1,      2
10
11-12 / -10 = 1,    - 2      // Both
12          = 2,    + 8

42dividend = int(input())
43print(&quot;Enter Divisor: &quot;)              # 4
44divisor = int(input())
45quotient = dividend // divisor;
46print(&quot;Quotient = &quot; + str(quotient))  # -7
47modulus = dividend % divisor;
48print(&quot;Modulus = &quot; + str(modulus))    # 1
49check = quotient * divisor + modulus; # -27
50print(&quot;Check = &quot; + str(check))
51

Note that, for the given inputs of different signs (-27 and 4), both the quotient and remainder/modulus are different between the languages but also that the restored check value is correct in both cases.

QUESTION

Bubble sort slower with -O3 than -O2 with GCC

Asked 2022-Jan-21 at 02:41

I made a bubble sort implementation in C, and was testing its performance when I noticed that the -O3 flag made it run even slower than no flags at all! Meanwhile -O2 was making it run a lot faster as expected.

Without optimisations:

It seems like the only significant difference to me is the apparent attempt to use SIMD, which seems like it should be a large improvement, but I also can't tell what on earth it's attempting with those pshufd instructions... is this just a failed attempt at SIMD? Or maybe the couple of extra instructions is just about edging out my instruction cache?

It looks like GCC's naïveté about store-forwarding stalls is hurting its auto-vectorization strategy here. See also Store forwarding by example for some practical benchmarks on Intel with hardware performance counters, and What are the costs of failed store-to-load forwarding on x86? Also Agner Fog's x86 optimization guides.

(gcc -O3 enables -ftree-vectorize and a few other options not included by -O2, e.g. if-conversion to branchless cmov, which is another way -O3 can hurt with data patterns GCC didn't expect. By comparison, Clang enables auto-vectorization even at -O2, although some of its optimizations are still only on at -O3.)

It's doing 64-bit loads (and branching to store or not) on pairs of ints. This means, if we swapped the last iteration, this load comes half from that store, half from fresh memory, so we get a store-forwarding stall after every swap. But bubble sort often has long chains of swapping every iteration as an element bubbles far, so this is really bad.

(Bubble sort is bad in general, especially if implemented naively without keeping the previous iteration's second element around in a register. It can be interesting to analyze the asm details of exactly why it sucks, so it is fair enough for wanting to try.)

Anyway, this is pretty clearly an anti-optimization you should report on GCC Bugzilla with the "missed-optimization" keyword. Scalar loads are cheap, and store-forwarding stalls are costly. (Can modern x86 implementations store-forward from more than one prior store? no, nor can microarchitectures other than in-order Atom efficiently load when it partially overlaps with one previous store, and partially from data that has to come from the L1d cache.)

Even better would be to keep buf[x+1] in a register and use it as buf[x] in the next iteration, avoiding a store and load. (Like good hand-written asm bubble sort examples, a few of which exist on Stack Overflow.)

If it wasn't for the store-forwarding stalls (which AFAIK GCC doesn't know about in its cost model), this strategy might be about break-even. SSE 4.1 for a branchless pmind / pmaxd comparator might be interesting, but that would mean always storing and the C source doesn't do that.

If this strategy of double-width load had any merit, it would be better implemented with pure integer on a 64-bit machine like x86-64, where you can operate on just the low 32 bits with garbage (or valuable data) in the upper half. E.g.,

(Or with BMI2 available from -march=native, rorx rsi, rax, 32 can copy-and-swap in one uop. Without BMI2, mov and swapping the original instead of the copy saves latency if running on a CPU without mov-elimination, such as Ice Lake with updated microcode.)

So total latency from load to compare is just integer load + one ALU operation (rotate). Vs. XMM load -> movd. And its fewer ALU uops. This does nothing to help with the store-forwarding stall problem, though, which is still a showstopper. This is just an integer SWAR implementation of the same strategy, replacing 2x pshufd and 2x movd r32, xmm with just mov + rol.

Actually, there's no reason to use 2x pshufd here. Even if using XMM registers, GCC could have done one shuffle that swapped the low two elements, setting up for both the store and movd. So even with XMM regs, this was sub-optimal. But clearly two different parts of GCC emitted those two pshufd instructions; one even printed the shuffle constant in hex while the other used decimal! I assume one swapping and the other just trying to get vec[1], the high element of the qword.

slower than no flags at all

The default is -O0, consistent-debugging mode that spills all variables to memory after every C statement, so it's pretty horrible and creates big store-forwarding latency bottlenecks. (Somewhat like if every variable was volatile.) But it's successful store forwarding, not stalls, so "only" ~5 cycles, but still much worse than 0 for registers. (A few modern microarchitectures including Zen 2 have some special cases that are lower latency). The extra store and load instructions that have to go through the pipeline don't help.

It's generally not interesting to benchmark -O0. -O1 or -Og should be your go-to baseline for the compiler to do the basic amount of optimization a normal person would expect, without anything fancy, but also not intentionally gimp the asm by skipping register allocation.

Semi-related: optimizing bubble sort for size instead of speed can involve memory-destination rotate (creating store-forwarding stalls for back-to-back swaps), or a memory-destination xchg (implicit lock prefix -> very slow). See this Code Golf answer.

QUESTION

How can I resolve the error "The minCompileSdk (31) specified in a dependency's AAR metadata" in native Java or Kotlin?

Asked 2022-Jan-01 at 22:24

The error message:

The minCompileSdk (31) specified in a dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties) is greater than this module's compileSdkVersion (android-30). Dependency: androidx.core:core-ktx:1.7.0-alpha02.

ANSWER

Answered 2022-Jan-01 at 17:57

You're going to need to update your compile SDK to 31. It sounds like it's currently set to 30. In your Gradle files there should be something like compileSdk in the android block.

Bump that up to 31. If that's an issue for some reason, you can also bump down your dependencies to versions that don't require that compile SDK version.

QUESTION

Why does the first element outside of a defined array default to zero?

Asked 2021-Dec-23 at 08:46

I'm studying for the final exam for my introduction to C++ class. Our professor gave us this problem for practice:

Explain why the code produces the following output: 120 200 16 0

1using namespace std;
2int main()
3{
4  int x[] = {120, 200, 16};
5  for (int i = 0; i &lt; 4; i++)
6    cout &lt;&lt; x[i] &lt;&lt; &quot; &quot;;
7}
8

The sample answer for the problem was:

The cout statement is simply cycling through the array elements whose subscript is being defined by the increment of the for loop. The element size is not defined by the array initialization. The for loop defines the size of the array, which happens to exceed the number of initialized elements, thereby defaulting to zero for the last element. The first for loop prints element 0 (120), the second prints element 1 (200), the third loop prints element 2 (16) and the forth loop prints the default array value of zero since nothing is initialized for element 3. At this point i now exceeds the condition and the for loop is terminated.

I'm a bit confused as to why that last element outside of the array always "defaults" to zero. Just to experiment, I pasted the code from the problem into my IDE, but changed the for loop to for (int i = 0; i < 8; i++). The output then changed to 120 200 16 0 4196320 0 547306487 32655. Why is there not an error when trying to access elements from an array that is outside of the defined size? Does the program just output whatever "leftover" data was there from the last time a value was saved to that memory address?

ANSWER

Answered 2021-Dec-13 at 20:55

It does not default to zero. The sample answer is wrong. Undefined behaviour is undefined; the value may be 0, it may be 100. Accessing it may cause a seg fault, or cause your computer to be formatted.

As to why it's not an error, it's because C++ is not required to do bounds checking on arrays. You could use a vector and use the at function, which throws exceptions if you go outside the bounds, but arrays do not.

QUESTION

Disabling the "Length Authoring Tools" (css unit selector) in Chrome Devtools Inspector

Asked 2021-Nov-18 at 14:28

The undesired functionality
In Chrome 95 there was introduced new functionality where the user can hover and click on the unit part of a css value to hotswap the unit.
The feature is part of a package solution that has been labeled "Length Authoring Tools" in the release notes, and can be seen in action and described in detail in the release notes on the official blog.

How can this feature be disabled?

Issue 1:

If a css-line in the inspector says padding: 0 10px; then the user can click the px-part of the line and open a selector that let's the user swap px to other units such as rem,vmax or in.
Clicking this part of the value no longer lets the user edit the entire value quickly. Most users already know what unit they desire to use beforehand, so they do not need to be helped to accidentally select pt or vw when working exclusively with px everywhere else.

Issue 2:

When selecting and copying properties from the inspector there is now inserted whitespaces/new lines between the value and the unit since the unit portion seems to be considered a separate element. This makes prototyping in the devtools and copy/pasting to external documents very tedious and broken.

ANSWER

Answered 2021-Nov-18 at 14:28

Updated answer 2021-11-16:

An option has been added to disable Length Authoring Tools in Chrome 96.

The following is mentioned in the official release notes for Chrome 96.

To disable Length Authoring Tools, navigate to this location in the DevTools and uncheck the checkbox:
Settings > Experiments > Enable CSS length authoring tools in the Styles pane.

But... The main issues regarding Length Authoring Tools have also been fully remedied in Chrome 96.

The initial incentive to disable these tools has been greatly diminished because of this.

A chevron will now appear to the right of the hovered value instead of reacting to clicks to the entire unit portion of it.

Copy paste now also works as intended.

Conclusion:
It is now possible to disable the Length Authoring Tools, but you might no longer need to.

Old answer:

You can't. (Though fixes are coming!)
It is not possible to toggle this feature in the current live stable release ( Chrome 95.0.4638.69 ).

Fixes have been added to Chromium ( [1], [2], [3] ) that are slowly making their way to the stable release of Chrome.

But help is on its way...

Chrome 96 is scheduled to be released on November 16 2021 (source), or ~3 weeks after October 28 according to this official tweet. It will at least contain a revert to free text editing of css properties (source). Hopefully version 96 will address the issue completely, but if it doesn't then the next major release is scheduled for January 4 2021 (If this issue is unresolved by then somebody at Google should be fired).

As for now, Chrome Canary seems to have these fixes implemented and might be considered an alternative solution to the issue if you find the current state of Length Authoring Tools unbearable.

Please be advised that Chrome Canary can be quite unstable.

This question and answer will be edited and corrected once there are real fixes in the live stable version.

QUESTION

Doesn't constraining the "auto" in C++ defeat the purpose of it?

Asked 2021-Nov-15 at 02:21

In C++20, we are now able to constrain the auto keyword to only be of a specific type. So if I had some code that looked like the following without any constraints:

1auto something(){
2  return 1;
3}
4
5int main(){
6  const auto x = something();
7  return x;
8}
9

The variable x here is deduced to be an int. However, with the introduction of C++20, we can now constrain the auto to be a certain type like this:

1auto something(){
2  return 1;
3}
4
5int main(){
6  const auto x = something();
7  return x;
8}
9std::integral auto something(){
10  return 0;
11}
12
13int main(){
14  const auto x = something();
15  return x;
16}
17

Doesn't this defeat the purpose of auto here? If I really need a std::integral datatype, couldn't I just omit the auto completely? Am I misunderstanding the use of auto completely?

ANSWER

Answered 2021-Nov-01 at 18:38

A constraint on the deduced auto type doesn't mean it needs to be a specific type, it means it needs to be one of a set of types that satisfy the constraint. Note that a constraint and a type are not the same thing, and they're not interchangeable.

e.g. a concept like std::integral constrains the deduced type to be an integral type, such as int or long, but not float, or std::string.

If I really need a std::integral datatype, couldn't I just omit the auto completely?

In principle, I suppose you could, but this would at the minimum lead to parsing difficulties. e.g. in a declaration like

1auto something(){
2  return 1;
3}
4
5int main(){
6  const auto x = something();
7  return x;
8}
9std::integral auto something(){
10  return 0;
11}
12
13int main(){
14  const auto x = something();
15  return x;
16}
17foo f = // ...
18

is foo a type, or a constraint on the type?

Whereas in the current syntax, we have

1auto something(){
2  return 1;
3}
4
5int main(){
6  const auto x = something();
7  return x;
8}
9std::integral auto something(){
10  return 0;
11}
12
13int main(){
14  const auto x = something();
15  return x;
16}
17foo f = // ...
18foo auto f = // ...
19

and there's no doubt that foo is a constraint on the type of f.
