Using vpn in some countries like north Korea(You don't even have access to foreign OS), China and Russia is illegal. But it's only illegal when you use it to access illegal/restricted websites.

Good Morning Guys. Multithreading is one the most complicated topics that I have ever faced in java (esp. synchronization methods and interthread communication). I understood all the theoretical concepts but my problem is implementation. Can someone also explain Producer-Consumer Problem using threads?

ps: You can refer me to any pdfs, Youtube video or web pages.

Hey people. I hope you are having a fantastic day.

Lately I have been having loads of fun with esolang related things. I decided to share some of the weirdest and coolest programming languages I have used.


ArnoldC - programming language based on the one-liners of Arnold Schwarzenegger.

AsciiDots - a programming language based entirely on ascii art.

Cheese++ - a programming language based almost entirely on the operational working principles of cheese.

Chef - a stack-based language where programs look like cooking recipes.

Cow - programming language was designed with the bovine in mind.

Emojicode - a open-source, full-blown programming language consisting of emojis.

FALSE - a programming language built to confuse everyone with an obfuscated syntax.

Folders - a language where the code is written with folders.

LOLCODE - a programming language inspired by lolspeak, the language expressed in examples of the lolcat Internet meme.

Malbolge - a programming language named after the eighth circle of hell in Dante's Inferno, the Malebolge, designed to be impossible to use.

Ook! - a programming language designed for orangutans.

reMorse - a programming language made to look like Morse code.

Rockstar - a programming language designed for creating programs that are song lyrics.

Omgrofl - a programming language where all commands are made up of internet acronyms, such as lol, wtf, brb, stfu, and more.

Shakespeare - A programming language created with the design goal to make the source code resemble Shakespeare plays.

Barcelona king, Lionel Messi, has reportedly clashed with goalkeeper, Marc-Andre ter Stegen as the crisis in the club's dressing room reaches a boiling point, according to Diaro Gol.

This is not the first time Messi and the German shot-stopper have fallen out at Barcelona as they have had issues in the past as well.

According to the newspaper, the Argentine superstar and the goalkeeper have had a massive bust-up that has seen their relationship falling out completely.

The Spanish newspaper said that the reason for their fight is because Messi had opted for Keylor Navas as his first choice during the voting for the FIFA The Best awards.

Messi went on to choose Bayern Munich's Manuel Neuer and Atletico Madrid's Jan Oblak as his second and third choices.

This was rather seen as quite a shocking choice of votes from the South American superstar who generally always voted for his teammates.

And his decision of snubbing Marc-Andre ter has not gone down well with the goalkeeper.

Diaro Gol reports that Ter Stegen has even reconsidered his future at the club despite renewing his contract with the club recently.

Ter Stegen has now reportedly put a hold on his autobiography movie, with the reason being that he wants his movie to be made next season when Messi is expected to leave Camp Nou.

It is certain that Messi will leave the club next summer, however, as of now, there seems to be no offer.

Godx:


In the last 3 matches without Messi, the whole team was flying.
All players moved around a field freely and passed freely. They had several passing options.
When Messi is on a field, our players turn into braindead zombies who are afraid of him, who can't pass freely anymore. Messi takes every ball, slows down and plays some stupid hero balls. Messi is a huge reason why we are slow in a build up and attack and why teams are parking a bus.

Imagine a match without Messi:
= if Coutinho has a counter, he will release a pass fast to Braith or Griezz.
And we will shoot 10 seconds later.

The same action with Messi on a field: Cou can't play a fast pass. He needs to slow down and pass to Messi. Braith and Griezz won't get the ball behind the defence in a counterattack.
Messi will slow down, dwell on a ball, wait until the opponent parks the bus and then he'll try a hero looped through ball to Alba or some weird, illogical shit. Once out of 10 attempts, that pass will work and some fans will say: but but but he had 2 key passes. Yes, he did.
But he lost like 18 other balls, killed counters, killed the movement from our attackers etc.

He is ruining majority of actions and his decisions are quite dumb lately.

People laughed at Kiev and Ferenc.
We could have scored 10+ easy goals in 2 matches without Messi.

But when Messi returned against a mighty Cadiz, we play worse and slower than ever.

You don't need to be a Sherlock to figure out why.

Well, every programming is real programming. I suppose.


So what's your favorite data structure?

For now LL and Q

Karleb:
No need. Most people aren't interested anyways.

But that's the real programming!

cixak95211:

Hmmmm

salvationproject:
tnk u sir

Never really used methods cuz it was no real reusability of codes needed but just as u said, the code would have been neater

okay

Please mods we really need a section in nairaland dedicated for DSA. What Do You Guys Think?
DSA is very important in the life of every programmer and we need a section here where programmers can meet up and solve DSA problems.

Guys I need someone who will explain what time complexity(Linear time, quadratic time, logarithmic time etc.). It has been holding me back since. Learning data structures and its implementations + Algorithms are very easy.

Your code would be cleaner if you break common operations there into classes and methods.

parkervero:
If you code in java your IDE should warn you na. All the 3 major java IDEs will warn you of missing semi colon(

IDE reports common syntax errors but not all ooo

cixak95211:
lol . . funny but you should learn to use a debugger
instead of having to manually screen every line trying to find where you did a typo or didn't add a terminator . . .

I don't know how to use debuggers

TheHulk616:
messi is overrated

Hmmm You're right

Mine is that I normally forget to terminate some statements (I use syntactically written languages(Java, C++ etc.) not dynamically written ones(Python, kotlin etc.)) and also if I want to compile a program using PowerShell I often use backward slashes instead of forward slashes while inputting the program's directory. The latter made me debug a bugless code for over one hour *laughs* trying to find something that's not there. I later found out that I used backward slashes (Even though I was facially happy but deep inside I was filled with anger).

Share Yours!

TheHulk616:

I think according to Java... Global variables are the ones that can be used by every thing in the class and local variables are variables that can be used only in a method ,inner class or code block that it was created

Example:
Public class MyClass{
public int variable:// this is a global variables
}

Public void VariMethod(int a){
//a is a local variable
}


Accept my humble explanation bro

I nor too sabi

cc peacettw

Bro global variables have different meanings, it depends on language that you're using. how that language defines it determines its characteristics.
for example a global variable in C language is different from that in java(Technically java doesn't support global variable). lemme use C to describe it first.
A global variable in C is a variable declared outside the main function/subroutine /method or other functions. The variable is static in nature this means that it can be accessed by any part of the program(that is other .c files created for that particular project) and it's independent of any block. But a local variable is a variable declared inside a block only the code inside the block have access to this variable. It can't be accessed by codes outside the block. The life time of the variables is one of factors that differentiate the two variable; the life time of global variables end when the program execution end while the life time of a local variable ends when the program control exits the block it is defined in.
C Code snippet
inside main.c file:
#include <stdio.h>
#include <stdlib.h>
//this is a global variable
int myvar;

int main(){
int myvar2;//a local variable since it's in the main block and not modified by static.
static int myvar3;//Another global variable.
//myvar can be accessed here.
}

Now in java people often say that global variable is declared using the the modifier public. Now let me ask you what about the modifier static.
Like I said initially that global variable is independent of any block but in the simple program you wrote the variable depends on the class block which makes the instance variable a local one.
Java doesn't support global variable since using public to define a variable in a class will only make that variable accessible through the object of the class the variable is defined in. Mind you that what you declared in that MyClass Class is an instance variable.
In java to achieve something that is similar to a global variable but not a GV o! Declare a variable using public static modifier.

Look at this code snippet:

class MyClass{
public static int myvar;

//Accesing myvar3
Main.myvar3 = 3;

//myvar2 is invisible here.
}

class Main{
public static void main(Strng[] args){
int myvar2;
static myvar3;
//myvar is visible here
MyClass.myvar=10;
}
}

The code snippet above has shown you the actual thing these modifiers do. Notice that I initialized myvar in Main class using MyClass.myvar. The static modifier made this variable to act like a global variable. The static made the variable independent of the object of MyClass, that's we can access it from the class directly without creating an object of MyClass. So as myvar3 which we accessed in MyClass using Main.myvar3. Also notice that I didn't put public there because all the variable declared inside a class is a public modified variable as far as it's not modified with "private".

These might be confusing but with constant practicing you will scale through.

please we need this on front page. This trend is really educative.

If you want to be a rugged coder, forget two of them... Learn HTML and CSS as much as you can.

CSS might seem confusing at first but as you master it, its like difference between motor mechanic and ordinary motor driver.

Dreamweaver and Wordpress uses WYSIWYG approach that's What you see is what you get. In other to be good(extremely good) at both you must know HTML,CSS and JavaScript because they make use of these technologies especially Dreamweaver. WordPress and Dreamweaver is a normal tool web designers not developers use to create static websites. But a professional web developer can use it to create both dynamic and static website.
If you're a web designer using only Dreamweaver/Wordpress is good but In other to be a full stack developer you need to drop those fancy applications and learn it the traditional way(HTML<CSS<JAVASCRIPT & ONE SERVERSIDE LANGUAGE)

talk2hb1:
C =Pointer
Java = OOP, and multi threading
But las las it does pay off

OOP was too easy in java for me but multithreading na one kind demon be that and it's something that you can't skip. it very important when developing desktop software and web applications.

Sulele04:
c++ - pointers and lamda expressions.
javascript - asynchronous programming
c# - my favorite programming language, maybe the functional programming part gave me problems sha but if i play best of post malone and open jetbrains rider my favorite ide there is c# or .net problem i cannot solve

I think asynchronous programming in JavaScript is synonymous to multithreading in java.

Ogah lalasticlala fp let's read from others.

Mine:
Java -> Multithreading Programming And Annotations
In Java even after watching the videos, I was still confused especially that multithreading programming. I had to download this books(Java concurrency I practice; The art of multiprocessor programming; and Concurrency in Java and design principles and pattern) and they really helped me a lot. But it was hard I had to spend hours (12 -> 13 hours) studying and practicing everyday, I worked like a beaver that period. It wasn't easy but it paid off.

C Language -> Pointers and I/O + Operating System.
Dealing with pointers in C initially was confusing but I practiced a lot in C and with time I mastered it. I used three to four textbooks and it was so stressful. Operating systems offed me especially when I was studying about processes, pipes and schedulers etc. men! This one rendered me speechless.

I learnt recently that most people often use the terms web design and web development interchangeably. So today I'm going to show you guys how Web design is different from web development.
There are two primary jobs involved in creating a website: the web designer and web developer, who often work closely together on a website. The web designers are responsible for the visual aspect, which includes the layout, coloring and typography of a web page. Web designers will also have a working knowledge of markup languages such as HTML and CSS, although the extent of their knowledge will differ from one web designer to another. Particularly in smaller organizations, one person will need the necessary skills for designing and programming the full web page, while larger organizations may have a web designer responsible for the visual aspect alone.

WEB DESIGN:
The term "web design" is normally used to describe the design process relating to the front-end (client side) design of a website including writing markup. The different areas of web design include web graphic design; user interface design (UI design); authoring, including standardized code and proprietary software; user experience design (UX design); and search engine optimization.

Tools and technologies:
Web designers use a variety of different tools depending on what part of the production process they are involved in. These tools are updated over time by newer standards and software but the principles behind them remain the same. Web designers use both vector and raster graphics editors to create web-formatted imagery or design prototypes. Technologies used to create websites include W3C standards like HTML and CSS, which can be hand-coded or generated by WYSIWYG editing software. Other tools web designers might use include mark up validators and other testing tools for usability and accessibility to ensure their websites meet web accessibility guidelines.

Skills and techniques:
1] Marketing and communication design
2] User experience design and interactive design(UX/UI)
3] Motion graphics
4] Quality of code
5] Responsive web design (RWD)
6] Adaptive web design (AWD)
7] Progressive enhancement etc

Software:
*Adobe Photoshop
*Adobe Illustrator
*Sketch (software)
*Affinity Designer
*Inkscape

Occupations:
1] Graphic designers to create visuals for the site such as logos, layouts and buttons
2] Internet marketing specialists to help maintain web presence through strategic solutions on targeting viewers to the site, by using marketing and promotional techniques on the internet
3] SEO writers to research and recommend the correct words to be incorporated into a particular website and make the website more accessible and found on numerous search engines
4] Internet copywriter to create the written content of the page to appeal to the targeted viewers of the site
5] User experience (UX) designer incorporates aspects of user-focused design considerations which include information architecture, user-centered design, user testing, interaction design, and occasionally visual design.



WEB DEVELOPMENT:
Among Web professionals, "Web development" usually refers to the main non-design aspects of building Web sites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills.
There are three kinds of Web developer specialization: front-end developer, back-end developer, and full-stack developer. Front-end developers are responsible for behavior and visuals that run in the user browser, while back-end developers deal with the servers.
There are many open source tools for Web development such as BerkeleyDB, GlassFish, LAMP (Linux, Apache, MySQL, PHP) stack and Perl/Plack.

Skill Required:
[1]HTML/XHTML, CSS, JavaScript and jQuery.
[2]Server/client side architecture like all or some of the above mentioned.
[3]Programming/Coding/Scripting in one of the many server-side languages or frameworks (e.g., Perl, Python, Ruby, PHP, Go, CFML - ColdFusion, Java
[4]ASP, ASP.NET, Node.js)
[5]Ability to utilize a database
[6]Creating single page application with use of front-end tools such as EmberJS, ReactJS or AngularJS

In conclusion Web Design has to do with the visual aspect of a website or web app (UI/UX) while web development has to do with both the front and server side of a website/web app.

Thank You Nairalanders!.
