Very amused every time someone discovers the ultimate way to do OOP in its truest, most polymorphic, most object-oriented form and its just immutable classes with public instance variables and no methods and no inheritance being transformed through singleton classes with no instance variables and one side-effect-free method, potentially taking a function as a parameter or returning another single method class. Brother you just reinvented functional programming.

useful information: How to get a USB Blu-Ray player to work on your computer

Not a post about vintage technology, just an explanation of what you think might be simple to do but isn't: There are Blu-Ray players that plug into your computer by USB, and you discover that just plugging it in doesn't make it work* in the same manner that CD-RWs or DVD-RWs are automatically recognised and function. You will see "BR Drive" in My Computer and the name of whatever movie you have inserted, but that's as far as you're able to go.

*There is software you can buy to make a Blu-Ray (internal or external) function, sure, and if an internal came with your computer it's likely already installed -- but if you're like me you don't have that software, you're cheap and won't pay for software, and you want to use what you have installed already or find free solutions.

Looking in the Blu-Ray drive's package, there's not a lot of info about what you're supposed to do. The above no-name Blu-Ray player cost $40 from a popular website; name-brand ones can set you back $120 or so. Looking around online for those instructions, I never saw the whole set of directions in one place, I had to cobble them together from 2 or 3 sites. And so here I share that list. To keep out of trouble, I'm not linking any files -- Google will help you.

Get VLC, the free video player available for pretty much any operating system. Thing is, it doesn't come with the internals to make it work with Blu-Ray even if when you go to the Play Media menu there is a radio button for selecting Blu-Ray.

Get MakeMKV, a decoder for reading Blu-Ray disks. This had been totally free during the beta testing period but it's come out and has a month or two trial period you can work in.

Get Java if you don't already have it. Reason for this is, the menu systems on Blu-Ray disks uses this... technically it's not required, however it does mean you don't have options such as special features, language and sound changes, or scene selection if you don't have Java installed; insert a disk, it can only play the movie.

Get the file libaacs.dll online so you have AACS decoding. I am told it hasn't been updated in awhile so there may be disks produced after 2013 that won't work right, but you won't know until you try.

There's a set of keys you will also want to have so that the player knows how to work with specific disks, and so do a search online for the "FindVUK Online Database". There will be a regularly-updated keydb.cfg archive file on that page to pick up.

Got those three programs installed and the other two files obtained? Okay, here are your instructions for assembly...

In VLC: go to Tools, Prefs, click "show all"… under the Input/Codecs heading is Access Modules then Blu-Ray: Select your region, A through C. You can change this if you need to for foreign disks. Next related action: go to My Computer and C:, click into Program Files and VLC, and this is where you copy the libaacs.dll file to.

In MakeMKV: click View, then Preferences, and under Integration - add VLC.

Confirm that Java is set up to work with VLC by going to the computer's Control Panel, going to System Properties, and into Environment Variables. Click System Variables, and click New to create this key if it doesn't already exist: … Name: Java … Value: [the location of the Java 'jre#.##' folder... use Browse to find it in C:\Program Files\Java]

Let's go back into My Computer and C:, this time go to Program Data, and then do a right-click in the window and select New and Folder. Rename this folder "aacs" (without the quotes), and then you click into it and copy the keydb.cfg file here.

REBOOT.

And now you should be able to recognise Blu-Ray disks in your player and play them. Three troubleshooting notes to offer in VLC:

"Disk corrupt" -- this means MakeMKV has not decoded and parsed the disk yet, or that you don't have the libaacs.dll in place so that it can decode the disk. ...After checking the VLC folder for the DLL to make sure, launch MakeMKV, then go to File, Play Disk, and select the Blu-Ray drive. Now it will grind a bit and figure out the disk's contents.

A note appears when a movie starts saying there will be no menus, but the movie plays fine -- Java isn't running. ...Invoke Java by going to the Java Settings in Start: Programs. You don't have to change anything here, so Exit, then eject the disk and put it back in to see if the movie's menu now appears.

Buffering between chapters, making the movie pause for a few seconds? There is a setting for this but I need to find that info page again for where that is. (If you find it, tell me where it is!)

I don't claim to know a lot but if you have any questions I might have some answers or suggestions. So far I've watched "Office Space" and Disney's "Coco" without any issues beside occasional buffering.

[mitigatedchaos]

Okay, I'm not generally one for dogwhistle-based thinking, but why is your favorite rap song by "a Dutch drum and bass group" called "Black Sun Empire"? On further Googling the official explanation is that it is a Star Wars reference, but this seems dubious to me at best

Dawn of a Dark Day feat. UK hip hop group Foreign Beggars is an excellent example of something that's quite rare: cyberpunk rap that's actually good.

descend to synapse chill factor sixty microverse entered so black, it's slipstream dip both the headlights melt into background

I've never found another track like it.

I'm going to assume that you're not a long-term reader, or it would be obvious why someone who posted fake discourse about parents cryogenically freezing their children would like this song.

Probably the best cyberpunk/post-cyberpunk anime is 2002's Ghost in the Shell: Standalone Complex. Some songs from that series have rap segments, but they don't really add to the music, such as with Origa feat. Heartsdales - Player.

Origa sounds amazing, but everyone who has ever heard one of the tracks featuring her already knows that.

The problem for Heartsdales is that it's usually much easier for a man to pose as tough and intimidating than it is for a woman, and even then, proper intimidation is subtle and depends on a connection to a background of power, or the ability to convincingly fake that connection.

What makes Dawn of a Dark Day so unique is that it's clearly from the perspective of a team of cyborg combat operatives, or following them very closely. It's also abstract enough that it doesn't fall into Ren Faire/Steampunk dorkiness. That's a fine line to tread, and it takes actual talent.

In real life, we don't sing songs about computer hacking, even though computer hacking is one of the most sci-fi elements of the current era.

Imagine a song about a combat cyborg team in the style of a whaling song, talking about cleaning ports and hacking mainframes. This would be much more understandable to contemporary outsider audiences than a line like, "cyberbrain circus - brace for the kickback."

In the cyberpunk world, the cyborg combat team would talk using the actual professional jargon from their field, which would be more specific to their time and place. For example, contemporary computer programmers would complain about Java, a specific programming language, about which they would have specific complaints (such as preferring dynamic typing, or Java being too verbose).

Thus, a whaling-style song, "dust the ports and hack the servers," which doesn't require knowing the specifics, would be something either written from an outsider's perspective, probably as a joke, or written from an insider's perspective, also probably as a joke.

To hit the right band, then, requires writing something from the perspective of an insider (even though insiders would not tend to write songs), that's intelligible to people from our world with some background knowledge of genre, that hits on the sci-fi elements related to the genre (rather than just being a generic love song), without making them overpowering, by baking them into the assumptions of the text.

To use a non-musical example, the original special collector's edition Mass Effect hoodie (left) is subtle and was popular for a while, while some subsequent designs by third parties (right) were much louder.

The design on the left is appropriate for a wide variety of social environments, while the design on the right would require a higher degree of social aptitude to get away with wearing wear in many social environments, and would be more suitable for a video game club or anime convention.

This is part of the general thing where being "cool" is about making things look effortless, and not looking like a tryhard.

Particularly, for the hoodie on the right, there's a mismatch between style and substance, in which it is trying to "borrow" power from a fictional suit of armor from a video game. (This mismatch is the general reason that trying to lean too hard on fiction is cringe; there's not enough substance relative to what someone is trying to do with it.)

Some of you may remember an Indiegogo campaign for a samurai armor hoodie. I'm not saying that everything should be understated. Sometimes, artistically, you're better off committing to the bit.

Now, back to music.

The band Gunship are not a rap outfit, but seem to have been quite successful with a lot of their sci-fi-themed content, such as this video with 3.9 million views:

They do a good job at finding the balance.

Another musical act, Perturbator, got 5.4 million views with a music video about rogue sentient androids (Perturbator - Sentient, which contains nudity).

The successor series for Standalone Complex, SAC_2045, has the song Millennium Parade - Fly With Me, which is better as rap music than the rap segment of Origa - Player, but isn't cyberpunk-themed directly.

Cyberpunk 2077 has, for example, Konrad OldMoney feat. Taelor Yung - Day of Dead, which is great for an action scene, but also isn't directly cyberpunk:

No Save Point, also from 2077, has a great line, "When a fortune cookie tells me I'm fucked, I just shrug," and ain't that Night City for you? They put some work in on this one, but I don't vibe with it as much musically.

Anyhow, that's why Dawn of a Dark Day is my favorite.

If you'd like, I can explain some of the recent politics of dog-whistles tomorrow or the day after.

Fun fact: the name of the programming language "C#" is actually five consecutive jokes layered on top of each other because programmers have nothing better to do.

Go with me on a brief history tour:

BCPL

Early programming language invented nearly 60 years ago

No jokes here, this one just stands for "Basic Combined Programming Language"

B

Designed to be a simpler, smaller substitute for BCPL

What would you name something that's "BCPL in less space"? Why, B, of course! It doesn't stand for anything, it's just BCPL with 75% fewer letters.

C

Designed to advance the ideas in B further forwards

What do you get if you move beyond B in the alphabet?

C++

Based on C, but with object-oriented features added on top

In C, adding "++" to the end of a number increments it by one, so this name basically says "slightly more than C"

C#

It's C++ but with even more object-oriented features, but also with a bunch of funky Java-inspired changes

If "C++" is "slightly more than C", maybe we could call it "C++++"? But that looks ridiculous, let's arrange those pluses into a square and connect them together.

For one final bonus joke, doing this makes it read as "C Sharp", which is of course the musical note one semitone higher than the C note, making it a second way to say "slightly more than C"

All together, "C#" is the culmination of five jokes that together say "better in a different way than, but still even better than the other language that's better than, the language that's more advanced than the language that's smaller than BCPL"

What Is The Difference Between Web Development & Web Design?

In today’s world, we experience the growing popularity of eCommerce businesses. Web designing and web development are two major sectors for making a difference in eCommerce businesses. But they work together for publishing a website successfully. But what’s the difference between a web designers in Dubai and a web developer?

Directly speaking, web designers design and developers code. But this is a simplified answer. Knowing these two things superficially will not clear your doubt but increase them. Let us delve deep into the concepts, roles and differentiation between web development and website design Abu Dhabi.

What Is Meant By Web Design?

A web design encompasses everything within the oeuvre of a website’s visual aesthetics and utility. This might include colour, theme, layout, scheme, the flow of information and anything related to the visual features that can impact the website user experience.

With the word web design, you can expect all the exterior decorations, including images and layout that one can view on their mobile or laptop screen. This doesn’t concern anything with the hidden mechanism beneath the attractive surface of a website. Some web design tools used by web designers in Dubai which differentiate themselves from web development are as follows:

● Graphic design

● UI designs

● Logo design

● Layout

● Topography

● UX design

● Wireframes and storyboards

● Colour palettes

And anything that can potentially escalate the website’s visual aesthetics. Creating an unparalleled yet straightforward website design Abu Dhabi can fetch you more conversion rates. It can also gift you brand loyalty which is the key to a successful eCommerce business.

What Is Meant By Web Development?

While web design concerns itself with all a website’s visual and exterior factors, web development focuses on the interior and the code. Web developers’ task is to govern all the codes that make a website work. The entire web development programme can be divided into two categories: front and back.

The front end deals with the code determining how the website will show the designs mocked by a designer. While the back end deals entirely with managing the data within the database. Along with it forwarding the data to the front end for display. Some web development tools used by a website design company in Dubai are:

● Javascript/HTML/CSS Preprocessors

● Template design for web

● GitHub and Git

● On-site search engine optimisation

● Frameworks as in Ember, ReactJS or Angular JS

● Programming languages on the server side, including PHP, Python, Java, C#

● Web development frameworks on the server side, including Ruby on Rails, Symfony, .NET

● Database management systems including MySQL, MongoDB, PostgreSQL

Web Designers vs. Web Developers- Differences

You must have become acquainted with the idea of how id web design is different from web development. Some significant points will highlight the job differentiation between web developers and designers.

Generally, Coding Is Not A Cup Of Tea For Web Designers:

Don’t ever ask any web designers in Dubai about their coding knowledge. They merely know anything about coding. All they are concerned about is escalating a website’s visual aspects, making them more eyes catchy.

For this, they might use a visual editor like photoshop to develop images or animation tools and an app prototyping tool such as InVision Studio for designing layouts for the website. And all of these don’t require any coding knowledge.

Web Developers Do Not Work On Visual Assets:

Web developers add functionality to a website with their coding skills. This includes the translation of the designer’s mockups and wireframes into code using Javascript, HTML or CSS. While visual assets are entirely created by designers, developer use codes to implement those colour schemes, fonts and layouts into the web page.

Hiring A Web Developer Is Expensive:

Web developers are more expensive to hire simply because of the demand and supply ratio. Web designers are readily available as their job is much simpler. Their job doesn’t require the learning of coding. Coding is undoubtedly a highly sought-after skill that everyone can’t entertain.

Final Thoughts:

So if you look forward to creating a website, you might become confused. This is because you don’t know whether to opt for a web designer or a developer. Well, to create a website, technically, both are required. So you need to search for a website design company that will offer both services and ensure healthy growth for your business.

The C Programming Language Compliers – A Comprehensive Overview

 C is a widespread-purpose, procedural programming language that has had a profound have an impact on on many different contemporary programming languages. Known for its efficiency and energy, C is frequently known as the "mother of all languages" because many languages (like C++, Java, and even Python) have drawn inspiration from it.

C Lanugage Compliers 

Developed within the early Seventies via Dennis Ritchie at Bell Labs, C changed into firstly designed to develop the Unix operating gadget. Since then, it has emerge as a foundational language in pc science and is still widely utilized in systems programming, embedded systems, operating systems, and greater.

2. Key Features of C

C is famous due to its simplicity, performance, and portability. Some of its key functions encompass:

Simple and Efficient: The syntax is minimalistic, taking into consideration near-to-hardware manipulation.

Fast Execution: C affords low-degree get admission to to memory, making it perfect for performance-critical programs.

Portable Code: C programs may be compiled and run on diverse hardware structures with minimal adjustments.

Rich Library Support: Although simple, C presents a preferred library for input/output, memory control, and string operations.

Modularity: Code can be written in features, improving readability and reusability.

Extensibility: Developers can without difficulty upload features or features as wanted.

Three. Structure of a C Program

A primary C application commonly consists of the subsequent elements:

Preprocessor directives

Main function (main())

Variable declarations

Statements and expressions

Functions

Here’s an example of a easy C program:

c

Copy

Edit

#include <stdio.H>

int important() 

    printf("Hello, World!N");

    go back zero;

Let’s damage this down:

#include <stdio.H> is a preprocessor directive that tells the compiler to include the Standard Input Output header file.

Go back zero; ends this system, returning a status code.

4. Data Types in C

C helps numerous facts sorts, categorised particularly as:

Basic kinds: int, char, glide, double

Derived sorts: Arrays, Pointers, Structures

Enumeration types: enum

Void kind: Represents no fee (e.G., for functions that don't go back whatever)

Example:

c

Copy

Edit

int a = 10;

waft b = three.14;

char c = 'A';

five. Control Structures

C supports diverse manipulate structures to permit choice-making and loops:

If-Else:

c

6. Functions

Functions in C permit code reusability and modularity. A function has a return kind, a call, and optionally available parameters.

Example:

c

Copy

Edit

int upload(int x, int y) 

    go back x + y;

int important() 

    int end result = upload(3, 4);

    printf("Sum = %d", result);

    go back zero;

7. Arrays and Strings

Arrays are collections of comparable facts types saved in contiguous memory places.

C

Copy

Edit

int numbers[5] = 1, 2, three, 4, five;

printf("%d", numbers[2]);  // prints three

Strings in C are arrays of characters terminated via a null character ('').

C

Copy

Edit

char name[] = "Alice";

printf("Name: %s", name);

8. Pointers

Pointers are variables that save reminiscence addresses. They are powerful but ought to be used with care.

C

Copy

Edit

int a = 10;

int *p = &a;  // p factors to the address of a

Pointers are essential for:

Dynamic reminiscence allocation

Function arguments by means of reference

Efficient array and string dealing with

9. Structures

C

Copy

Edit

struct Person 

    char call[50];

    int age;

;

int fundamental() 

    struct Person p1 = "John", 30;

    printf("Name: %s, Age: %d", p1.Call, p1.Age);

    go back 0;

10. File Handling

C offers functions to study/write documents using FILE pointers.

C

Copy

Edit

FILE *fp = fopen("information.Txt", "w");

if (fp != NULL) 

    fprintf(fp, "Hello, File!");

    fclose(fp);

11. Memory Management

C permits manual reminiscence allocation the usage of the subsequent functions from stdlib.H:

malloc() – allocate reminiscence

calloc() – allocate and initialize memory

realloc() – resize allotted reminiscence

free() – launch allotted reminiscence

Example:

c

Copy

Edit

int *ptr = (int *)malloc(five * sizeof(int));

if (ptr != NULL) 

    ptr[0] = 10;

    unfastened(ptr);

12. Advantages of C

Control over hardware

Widely used and supported

Foundation for plenty cutting-edge languages

thirteen. Limitations of C

No integrated help for item-oriented programming

No rubbish collection (manual memory control)

No integrated exception managing

Limited fashionable library compared to higher-degree languages

14. Applications of C

Operating Systems: Unix, Linux, Windows kernel components

Embedded Systems: Microcontroller programming

Databases: MySQL is partly written in C

Gaming and Graphics: Due to performance advantages

Consistency and Reducibility: Which is the theorem and which is the lemma?

Here's an example from programming language theory which I think is an interesting case study about how "stories" work in mathematics. Even if a given theorem is unambiguously defined and certainly true, the ways people contextualize it can still differ.

To set the scene, there is an idea that typed programming languages correspond to logics, so that a proof of an implication A→B corresponds to a function of type A→B. For example, the typing rules for simply-typed lambda calculus are exactly the same as the proof rules for minimal propositional logic, adding an empty type Void makes it intuitionistic propositional logic, by adding "dependent" types you get a kind of predicate logic, and really a lot of different programming language features also make sense as logic rules. The question is: if we propose a new programming language feature, what theorem should we prove in order to show that it also makes sense logically?

The story I first heard goes like this. In order to prove that a type system is a good logic we should prove that it is consistent, i.e. that not every type is inhabited, or equivalently that there is no program of type Void. (This approach is classical in both senses of the word: it goes back to Hilbert's program, and it is justified by G��del's completeness theorem/model existence theorem, which basically says that every consistent theory describes something.)

Usually it is obvious that no values can be given type Void, the only issue is with non-value expressions. So it suffices to prove that the language is normalizing, that is to say every program eventually computes to a value, as opposed to going into an infinite loop. So we want to prove:

If e is an expression with some type A, then e evaluates to some value v.

Naively, you may try to prove this by structural induction on e. (That is, you assume as an induction hypothesis that all subexpressions of e normalize, and prove that e does.) However, this proof attempt gets stuck in the case of a function call like (λx.e₁) e₂. Here we have some function (λx.e₁) : A→B and a function argument e₂ : A. The induction hypothesis just says that (λx.e₁) normalizes, which is trivially true since it's already a value, but what we actually need is an induction hypothesis that says what will happen when we call the function.

In 1967 William Tait had a good idea. We should instead prove:

If e is an expression with some type A, then e is reducible at type A.

"Reducible at type A" is a predicate defined on the structure of A. For base types, it just means normalizable, while for function types we define

e is reducable at type A→B ⇔ for all expressions e₁, if e₁ is reducible at A then (e e₁) is reducible at B.

For example, an function is reducible at type Bool→Bool→Bool if whenever you call it with two normalizing boolean arguments, it returns a boolean value (rather than looping forever).

This really is a very good idea, and it can be generalized to prove lots of useful theorems about programming languages beyond just termination. But the way I (and I think most other people, e.g. Benjamin Pierce in Types and Programming Languages) have told the story, it is strictly a technical device: we prove consistency via normalization via reducibility.

❧

The story works less well when you consider programs that aren't normalizing, which is certainly not an uncommon situation: nothing in Java or Haskell forbids you from writing infinite loops. So there has been some interest in how dependent types work if you make termination-checking optional, with some famous projects along these lines being Idris and Dependent Haskell. The idea here is that if you write a program that does terminate it should be possible to interpret it as a proof, but even if a program is not obviously terminating you can still run it.

At this point, with the "consistency through normalization" story in mind, you may have a bad idea: "we can just let the typechecker try to evaluate a given expression at typechecking-time, and if it computes a value, then we can use it as as a proof!" Indeed, if you do so then the typechecker will reject all attempts to "prove" Void, so you actually create a consistent logic.

If you think about it a little longer, you notice that it's a useless logic. For example, an implication like ∀n.(n² = 3) is provable, it's inhabited by the value (λn. infinite_loop()). That function is a perfectly fine value, even though it will diverge as soon as you call it. In fact, all ∀-statements and implications are inhabited by function values, and proving universally quantified statements is the entire point of using logical proof at all.

❧

So what theorem should you prove, to ensure that the logic makes sense? You want to say both that Void is unprovable, and also that if a type A→B is inhabited, then A really implies B, and so on recursively for any arrow types inside A or B. If you think a bit about this, you want to prove that if e:A, then e is reducible at type A... And in fact, Kleene had already proposed basically this (under the name realizability) as a semantics for Intuitionistic Logic, back in the 1940s.

So in the end, you end up proving the same thing anyway—and none of this discussion really becomes visible in the formal sequence of theorems and lemmas. The false starts need to passed along in the asides in the text, or in tumblr posts.

Introduction to Scala

Scala is a modern programming language that combines object-oriented and functional programming features.

It runs on the JVM (Java Virtual Machine), making it highly compatible with Java.

Scala is concise, expressive, and designed for scalability in software development.
