What are metasyntactic variables such as Foo, Bar? The difference between Slang, Jargon, and Techspeak.

The line between the vocabulary of hacker slang and technical programming and computer science is very thin and is not known well by programmers, many of whom are not hackers.

What is slang?

Slang is an informal language from mainstream English or non-technical subcultures (bikers, rock fans, surfers, etc). What is jargon Jargon, without a qualifier, denotes informal ‘slangy’ language peculiar to or predominantly found among hackers — the subject of this lexicon.

What is techspeak?

Techspeak is the formal technical vocabulary of programming, computer science, electronics, and other fields connected to hacking.

What is a metasyntactic word?

A word used in examples and understood to stand for whatever thing is under discussion, or any random member of a class of things under discussion. In the computer era, these words are called Metasyntactic variables because They are generally variables in the metalanguage used to talk about programs etc; They are variables whose values are often variables

Common metasyntactic words:

foo, bar, baz, quux, quuux, quuuux...:MIT/Stanford usage, now found everywhere (thanks largely to early versions of this lexicon!). At MIT (but not at Stanford), baz dropped out of use for a while in the 1970s and '80s. A common recent mutation of this sequence inserts quxbefore quux.bazola, ztesch:Stanford (from mid-'70s on).foo, bar, thud, grunt:This series was popular at CMU. Other CMU-associated variables include gorp.foo, bar, bletch:Waterloo University. We are informed that the CS club at Waterloo formerly had a sign on its door reading “Ye Olde Foo Bar and Grill”; this led to an attempt to establish “grill” as the third metasyntactic variable, but it never caught on.foo, bar, fum:This series is reported to be common at XEROX PARC.fred, jim, sheila, barney:See the entry for fred. These tend to be Britishisms.flarp:Popular at Rutgers University and among GOSMACS hackers.zxc, spqr, wombat:Cambridge University (England).shmeBerkeley, GeoWorks, Ingres. Pronounced /shme/ with a short /e/.foo, bar, baz, bongoYale, late 1970s.spam, eggsPython programmers.snorkBrown University, early 1970s.foo, bar, zotHelsinki University of Technology, Finland.blarg, wibbleNew Zealand.toto, titi, tata, tutuFrance.pippo, pluto, paperinoItaly. Pippo /pee�po/ and Paperino /pa�per�ee'�no/ are the Italian names for Goofy and Donald Duck.aap, noot, miesThe Netherlands. These are the first words a child used to learn to spell on a Dutch spelling board.oogle, foogle, boogle; zork, gork, borkThese two series (which may be continued with other initial consonents) are reportedly common in England, and said to go back to Lewis Carroll.

Foo Bar

When ‘foo’ is used in connection with ‘bar’ it has generally traced to the WWII-era Army slang acronym FUBAR (‘Fucked Up Beyond All Repair’ or ‘Fucked Up Beyond All Recognition’), later modified to foobar. Early versions of the Jargon File interpreted this change as a post-war bowdlerization, but it now seems more likely that FUBAR was itself a derivative of ‘foo’ perhaps influenced by German furchtbar (terrible) — ‘foobar’ may actually have been the original form.

ELECTRIC-POWERED PERSONAL CITY TRANSPORT VEHICLES

The increasing population density in many cities in the World causes traffic jams and time-wasting situations. Air pollutions made by fossil fuel consumption is one of the major reasons for global warming anywhere in the world. Governments and nongovernment organizations seek the solution for these mentioned problems. The first answer is adapting more people to public transportation that mainly electric-powered. The second one is to provide especially tax privilege for usage electric-powered vehicles in their countries. Automobile companies and relatively motorbike/bike producers generate high technology electric-power engines and apply these new engines to their vehicles with the parallel of the government’s requirements and efforts. In this post, we will provide useful information about the personal usage of the electric-powered vehicle for the cities.

People who live in many north-European countries such as Netherland has been used the bicycle for their daily city life, for instance, to go their work or coming back to their home. This situation is naturally accrued with the parallel of their customs and traditions. But people have altered their attention to electric-powered personal usage city transportation vehicles in the last decade.

Segway on in other name ginger was the first attempt to respond to the people’s requirements in these concepts. But the cost of it was expensive. The improvement in electric-powered engines and batteries, costs have decreased and many different firms started to produce these kinds of vehicles. Two-wheel electric vehicles that were named generally hover-board gained popularity all around the world. Children, teens, and adults purchase this model as an entertainment tool. But the electric-powered scooter followed the hoverboard and liked by many people who live in big cities as a personal transport vehicle.  

The low expense, being eco-friendly and the low energy consumption of electric-power personal vehicle has many different applications from east to west. Having been from 1 to 4 wheels alternatives, this new technology platforms extended their popularity day by day.

Some motorcycle and bicycle companies and new firms generate many different models for this purpose. People get familiar with these vehicles some purchase and some rent them for their personal usage in the city.

Quick Info about SSH and SSH KEYGEN?

What is ssh-keygen? Ssh meaning?

Ssh keygen is a tool for creating new authentication key pairs for SSH. Such key pairs are used for automating logins, single sign-on, and for authenticating hosts.

SSH Keys and Public Key Authentication

The SSH protocol uses public-key cryptography for authenticating hosts and users. The authentication keys, called SSH keys, are created using the keygen program. SSH introduced public key authentication as a more secure alternative to the older .rhosts authentication. It improved security by avoiding the need to have the password stored in files, and eliminated the possibility of a compromised server stealing the user's password.

Creating an SSH Key Pair for User Authentication

The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: ssh-keygen The result is: Generating public/private rsa key pair. Enter file in which to save the key (/home/user/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/user/.ssh/id_rsa. Your public key has been saved in /home/user/.ssh/id_rsa.pub. The key fingerprint is: SHA256:Up6KjbnEV4Hgfo75YM393QdQsK3Z0aTNBz0DoirrW+c user@host The key's randomart image is: +-------+ | . ..oo..| | . . . . .o.X.| | . . o. ..+ B| | . o.o .+ ..| | ..o.S o.. | | . %o= . | | @.B… . | | o.=. o. . . .| | .oo E. . .. | +---------+ First, the tool asked where to save the file. SSH keys for user authentication are usually stored in the user's .ssh directory under the home directory. However, in enterprise environments, the location is often different. The default key file name depends on the algorithm, in this case, id_rsa when using the default RSA algorithm. It could also be, for example, id_dsa or id_ecdsa. Then it asks to enter a passphrase. The passphrase is used for encrypting the key so that it cannot be used even if someone obtains the private key file. The passphrase should be cryptographically strong. You can add this to your ssh agent. You can also use ssh port. You can follow manual pages to ssh a command to a remote server.

Choosing an Algorithm and Key Size

SSH supports several public key algorithms for authentication keys. These include: rsa - an old algorithm based on the difficulty of factoring large numbers. A key size of at least 2048 bits is recommended for RSA; 4096 bits is better. RSA is getting old and significant advances are being made in factoring. Choosing a different algorithm may be advisable. It is quite possible the RSA algorithm will become practically breakable in the foreseeable future. All SSH clients support this algorithm. dsa - an old US Government Digital Signature Algorithm. It is based on the difficulty of computing discrete logarithms. A key size of 1024 would normally be used with it. DSA in its original form is no longer recommended. ecdsa - a new Digital Signature Algorithm standardized by the US government, using elliptic curves. This is probably a good algorithm for current applications. Only three key sizes are supported: 256, 384, and 521 (sic!) bits. We would recommend always using it with 521 bits since the keys are still small and probably more secure than the smaller keys (even though they should be safe as well). Most SSH clients now support this algorithm. ed25519 - this is a new algorithm added in OpenSSH. Support for it in clients is not yet universal. Thus its use in general purpose applications may not yet be advisable. The algorithm is selected using the -t option and key size using the -b option. The following commands illustrate: ssh-keygen -t rsa -b 4096 ssh-keygen -t dsa ssh-keygen -t ecdsa -b 521 ssh-keygen -t ed25519

Copying the Public Key to the Server ( ssh tunnel )

To use public-key authentication, the public key must be copied to a server and installed in an authorized_keys file. This can be conveniently done using the ssh-copy-id tool. Like this: ssh-copy-id -i ~/.ssh/tatu-key-ecdsa user@host Once the public key has been configured on the server, the server will allow any connecting user that has the private key to log in. During the login process, the client proves possession of the private key by digitally signing the key exchange.

Command and Option Summary

Here's a summary of commonly used ssh options to the keygen tool: -b “Bits” This option specifies the number of bits in the key. The regulations that govern the use case for SSH may require a specific key length to be used. In general, 2048 bits is considered to be sufficient for RSA keys. -e “Export” This option allows reformatting of existing keys between the OpenSSH key file format and the format documented in RFC 4716, “SSH Public Key File Format”. -p “Change the passphrase” This option allows changing the passphrase of a private key file with and , . -t “Type” This option specifies the type of key to be created. Commonly used values are: - rsa for RSA keys - dsa for DSA keys - ecdsa for elliptic curve DSA keys -i "Input" When ssh-keygen is required to access an existing key, this option designates the file. -f "File" Specifies the name of the file in which to store the created key. -N "New" Provides a new passphrase for the key. -P "Passphrase" Provides the (old) passphrase when reading a key. -c "Comment" Changes the comment for a key file. -p Change the passphrase of a private key file. -q Silence ssh-keygen. -v Verbose mode. -l "Fingerprint" Print the fingerprint of the specified public key. -B "Bubble babble" Shows a "bubble babble" (Tectia format) fingerprint of a key file. -F Search for a specified hostname in a known_hosts file. -R Remove all keys belonging to a hostname from a known_hosts file. -y Read a private OpenSSH format file and print an OpenSSH public key to stdout.

Null / Nullish Coalescing (Double Question Mark ??) operator in JavaScript and React.

The nullish coalescing operator (??) is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined and otherwise returns its left-hand side operand. Contrary to the logical OR (||) operator, the left operand is returned if it is a falsy value that is not null or undefined. In other words, if you use || to provide some default value to another variable foo, you may encounter unexpected behaviors if you consider some falsy values as usable (eg. '' or 0). const foo = null ?? 'bar'; console.log(foo); // output: "bar" const baz = 0 ?? 42; console.log(baz); // output: 0

Difference Between logical OR (||) and nullish coalescing (??) operators:

The common pattern is to use the logical OR operator (||): let foo; // foo is never assigned any value so it is still undefined let someDummyText = foo || 'Hello!'; But, due to || being a boolean logical operator, the left-hand-side operand was coerced to a boolean for the evaluation and any falsy value (0, '', NaN, null, undefined) was not returned. This behavior may cause unexpected consequences if you consider 0, '', or NaN as valid values. let count = 0; let text = ""; let qty = count || 42; let message = text || "hi!"; console.log(qty); // 42 and not 0 console.log(message); // "hi!" and not "" The nullish coalescing operator avoids this pitfall by only returning the second operand when the first one evaluates to either null or undefined (but no other falsy values): let myText = ''; // An empty string (which is also a falsy value) let notFalsyText = myText || 'Hello world'; console.log(notFalsyText); // Hello world let preservingFalsy = myText ?? 'Hi neighborhood'; console.log(preservingFalsy); // '' (as myText is neither undefined nor null)

Chaining and Nullish Coalescing Operators

React's create-react-app version 3.3.0 (released 5.12.2019) tool-chain supports the null-coalescing. // Optional chaining a?.(); // undefined if a is null/undefined b?.c; // undefined if b is null/undefined // Nullish coalescing undefined ?? 'some other default'; // result: 'some other default' null ?? 'some other default'; // result: 'some other default' '' ?? 'some other default'; // result: '' 0 ?? 300; // result: 0 false ?? true; // result: false Further reading: - The Easiest Way to Install Windows 10 with ISO File From USB Drive - What is CSS4?

A Complete Guide to Your PHP Server in 2020

One of the reasons why the professional developers use PHP for their web application is that PHP is a very suitable and reliable back-end programming language. In this article, you will find the complete guide to select your local/remote back-end server which runs PHP and provides necessary web tools all along. According to the StackOverflow’s 2018 survey, PHP the most used back-end language after Python and almost 1/3 of the professional developers use PHP to develop their web application. PHP as a Back-End Language  PHP is a programming language that runs on the server-side, also called the back-end side. The back-end is a part of the web application that runs in the server. In other words, it interacts with the server, gets some information and relays it to the front-end to display on the screen. You can do many things on the server by using PHP including CRUD (Create, Read, Update, Delete) operations. For example, when you submit a form on the web page, the back-end takes this data you filled in the form and passes it to the server, after that, the PHP code in the server saves that data in a database and sends some confirmation info to the front-side. Then the front-side displays the confirmation of your submit action. Using PHP as Back-end             You can use PHP, your goal can be developing a web application, writing a command line script or developing a desktop GUI application.             For developing a web application, you need PHP itself, a browser, a server supports PHP and a web hosting service. In the modern operating systems, there are web browsers, and in-built web servers (e.g. Windows: IIS and Linux/MacOS: Apache). After you obtain a web hosting, you can begin to write PHP code.             If you want to use PHP language for command line scripting you don’t need any servers or browsers, and also with the PHP-GTK extension, you can develop desktop GUI applications. Select your PHP Server Before you decide to develop a PHP web application, you must first select local web server for development purposesremote web server for hosting your products. In addition to PHP Servers, if you are using some other web-tools, it’s better to use third-party programs which provide these necessary tools together. Selecting a local PHP server.      XAMPP XAMPP is the most popular open-source PHP local server. XAMPP has a free Apache server and contains MariaDB, PHP, and Perl. It also supports many tools like MySQL, FileZilla, Mercury, Tomcat, and others. It allows programmers to test their applications easily. XAMPP is available for Linux, Windows and macOS systems. WAMP                 WampServer is a web server for Windows. WAMP is an alternative to XAMPP. It supports Apache, PHP, and MySQL. Its interface is an easy-to-use platform having Apache configurations, PHP configurations, WWW directory etc. MAMP             MAMP is a free PHP local server developed for macOS systems but can also be installed under Windows. It stands for Mac, Apache, MySQL, and PHP. It supports not only the Apache server but also Nginx as well.  MAMP PRO, a paid-version, allows you to create separate hosts for each of your projects. LAMP             LAMP stands for Linux, Apache, MySQL, and PHP. LAMP is developed for Linux operating systems and it includes FastCGI, OpenSSL, phpMyAdmin, ModSecurity, SQLite, Varnish, ImageMagick, xDebug, Xcache, OpenLDAP, ModSecurity, Memcache, OAuth, PEAR, PECL, APC, GD, cURL and other components and the following frameworks: ZendFramework, Symfony, CodeIgniter, CakePHP, Smarty, Laravel. LEMP LEMP is a variety of LAMP. LEMP stands for Linux, NGINX, MariaDB, and PHP (Because of the pronunciation of NGINX, “E” is used instead of “N”). Apache is replaced with the NGINX and also uses MariaDB for handling database operations. It also works fine as a relational database – just like MySQL but offers some other added functionalities. AMPPS AMPPS is a combination of WAMP, MAMP and LAMP stack. The platform offers 449 Apps along with Apache, MySQL, MongoDB, PHP, Perl & Python. The platform supports both MacOS, Linux and Windows operating systems. AMPPS web server enables you to focus more on web apps rather than maintaining them. AMPPS is provided by Softaculous. AMPSS stack includes everything for website development. You can do all complex functions with just a click.  WinNMP             WinNMP is a development stack for Windows. It provides a lightweight, fast and stable server, based on Nginx, MariaDB, Redis, and PHP. WPИ-XM             WPИ-XM is an open-source server for PHP development on Windows. WPИ-XM stands for : Windows, PHP, NGINX, Xdebug, MariaDB/MongoDB. WPИ-XM offers various easy-to-install services to developers. The stack consists of NGINX as the webserver, MariaDB as the database and PHP as the scripting and programming language. The stack includes essential utils for PHP development like Composer, Pickle, PHPUnit, phpcsfixer, PEAR out-of-the-box. EasyPHP-DEVSERVER             EasyPHP Devserver is a complete and ready-to-use web server for Windows including PHP, Apache, MySQL, Nginx, PhpMyAdmin, Xdebug, PostgreSQL. Devserver is portable, modular and easy to update and extend. Devserver allows you to set up a server with the same specifications as a production server. Since it is portable, you can develop locally anywhere. Selecting hosting PHP Server When you decide to deploy your web application, you must first select your hosting server. The hosting server hosts your application, provides some built-in resources like databases, caching tools and other tools for website optimization. Today, there are lots of open-source PHP servers available. Most of them use Apache as a server, while others prefer Nginx. You can compare PHP Hosting Plans from this link. EasyPHP-Webserver turns your computer into a ready-to-use personal and dedicated server for web, database, and FTP hosting. You can host your own website on your computer and share it on the internet. Your computer acts like a web hosting service You can tune Apache (host server), MySQL (database server), PHP (web development), Filezilla (FTP server). In conclusion, When you decide to use PHP as your back-end language, you should use a local web server for development and a remote webserver to host your application. In case you need additional web tools with PHP server, you should use stack programs that provide all necessary tools together such as XAMPP, WAMP, MAMP, LAMP, LEMP, AMPPS, WinNMP, WPИ-XM, EasyPHP-DevServer. After you developed your application locally, you need to select your hosting server to deploy it. Further Reading: - How to Hire a Great PHP Developer by Toptal Read the full article

What is CSS4? Does CSS 4 really exist?

TLTR; There is no CSS4 for now.

What is CSS?

Cascading Style Sheets (CSS) is a simple way of adding styles (e.g., fonts, colors) to web pages.

CSS1:

CSS first appeared on 10 October 1994. The first level of Cascading Style Sheets, level 1 was recommended by W3C on 17 Dec 1996. That specification is known as CSS1.

CSS2:

New revisions on CSS1 were made and resulted in the creation of level 2 of Cascading Style Sheets on 04 November 1997. This level 2 is recommended as CSS2 by W3C on 12 May 1998 (revised on 11 April 2008) CSS2 was built on CSS1 and most of the CSS1 stylesheets are valid on CSS2. CSS2 supports media-specific style sheets so that authors may tailor the presentation of their documents to visual browsers, aural devices, printers, braille devices, handheld devices, etc. This specification also supports content positioning, downloadable fonts, table layout, features for internationalization, automatic counters and numbering, and some properties related to the user interface.

CSS 2.1:

The most known revision to CSS2. Officially defined as Cascading Style Sheets Level 2 Revision 1. CSS 2.1 was recommended by W3C on 07 June 2011 and updated on 12 April 2016. CSS 2.1 corrects a few errors in CSS2 (the most important being a new definition of the height/width of absolutely positioned elements, more influence for HTML's "style" attribute and a new calculation of the 'clip' property), and adds a few highly requested features which have already been widely implemented.

CSS3:

CSS level 3, which was actually appeared in 1998, was under development until 2014. Unlike CSS2, which is a large single specification defining various features, CSS 3 is divided into several separate documents called "modules". Each module adds new capabilities or extends features defined in CSS 2. And it must be known that the CSS3 does not exist formally, is an extension of CSS 2.1. The term CSS3 refers to everything that was published after CSS 2.1.

CSS 4:

There is no single, integrated CSS4 specification because the specification has been split into many separate modules which level independently. Modules that build on things from CSS Level 2 started at Level 3. Some of them have already reached Level 4 or are already approaching Level 5. For example CSS Selectors level 4 which is being confused with CSS4, but it is just a module that is still in working draft and that some modern browsers already have implemented some parts of this specification. A W3C Community Group has been established in early 2020 in order to discuss and define such a resource. The actual kind of versioning is also up to debate, which means that the document once produced might not be called "CSS4".

How to earn money by guest posting? Here are guest blog websites paying writers.

In this blog, you will read how to and what and where to write as a guest blogger. Bonus: The ultimate list of paying blogs.

How to write a blog as a guest?

One of most likely probably the most troublesome parts of customer posting is discovering prime-of-the-line visitor working a weblog website online to submit after which going by way of the tactic of getting your visitor to publish guest posts on their web. Some websites could settle for visitor posts, nonetheless, when the viewers are simply tuning in for the weblog proprietor, you then accomplish that properly in case your goal is to assemble authority or get website visitors as soon as extra to your web site. Thus, guest running a blog is a win for the host weblog that’s publishing your guest publish, on account of they get a free piece of content material that they don’t have to either write themselves or pay a writer to compile. By writing excessive-high quality visitor posts on different web sites in your area of interest, you obtain valuable inbound hyperlinks, improve your Domain Authority, acquire more exposure to readers excited about your content material. Even in case your guest blogging thought was super, it is important that you can deliver a powerful piece of blog content that’s related to the blog page, matches their fashion and accomplishes some sort of strategic content material post. Then, after you’ve reached out to the blogger who’s content you featured in your visitor publish, you possibly can gauge their responsiveness and even pitch them on having you as a guest blogger—translating into even more prime quality hyperlinks back to your blog.

Important keys to writing guest blogs.

1. Fing guest blog websites regarding your interest. Is this website related to my brand? You need to make sure the readers fit within your target market. Although your current guest posts may have great substance and content, it won’t do you any good if they’re not published on the proper sites. 2. Try to write for credible blogs. But just because a website is relevant and has the same target audience as you do doesn’t mean you should write for it. Do some research. You want to find sites that already have lots of website traffic. It’ll be a waste of your time if you write for sites nobody reads. In addition to the advertisements, there are other ways to tell whether a blog is credible. For starters, if it’s a big name brand you know and recognize as an authority in your industry, it’s a safe bet to assume they already have lots of traffic. Reach out to websites to inquire about guests posting. You may be pleasantly surprised by their responses. As you know, blogging takes time. On average, it takes more than three hours to write a typical blog post. 3. Write an impressive introduction People reading your guest posts won’t navigate to your website unless they actually read your post. Considering that 43% of readers scan through posts and articles, the odds are against you that your content will get read in its entirety. Your opening lines are essential. Your headlines are even more important: You can also state an intriguing fact or statistic in your intro to pique the interest of the readers. Identify a problem. Hint at a solution that can be found in the post. Don’t be ambiguous. Be direct and get straight to the point. Talk about a subject your readers can relate to. Again, I’ll use this current post as an example. If you do this in your guest posts, people will be more likely to read the rest of your post and navigate to your website. 4. Include links to your own website Include natural hyperlinks within the content of your posts. Writing guest posts is one of my favorite ways for you to consistently build backlinks. If you do this correctly, people will click and be sent to your website directly. But that’s not all. Having backlinks on other credible websites will positively impact your SEO ranking. 5. Tell your story It should be clear from the beginning that you’re writing a guest post. This is the perfect time for you to master the art of storytelling. That’s because more than 90% of consumers want brands to deliver content that feels like a story. 6. Encourage the site to promote your guest posts You can politely ask them to share your guest posts on their social media pages. You can even ask them to send it to their email subscribers. A nice way to help the site meet your request is by offering to return the favor. You can tell them you’ll share the post on your social channels too. This benefits everyone. Their website will get more traffic. As a result, more people will see your guest post, which increases the chances of you getting more traffic to your own site. 7. Track your results You’ll need to track the results with these types of analytic tools to evaluate your performance properly. Each hyperlink in your guest post can have a unique link. You’ll be able to see exactly how much traffic comes from these links. If nobody is clicking on these links, obviously your strategy isn’t working. There are a few different ways to go from here. You could potentially change the style of your posts and the placement of your hyperlinks within the content. 8. Keep writing Don’t just write one guest post and think that’s going to be enough to spike your site traffic. Continue writing for that blog if they allow you to. Once per month or so should be sufficient. Write for as many sites as possible, without spreading yourself too thin. You don’t want your own blog or brand to suffer as a result of your guest blogging. Make sure you stay balanced and don’t let your quality suffer. But the more sites you write for, the greater your chances of getting higher traffic to your website will be. 9. Summary to popular belief, guest blogging is a great content marketing strategy. It’s an inexpensive way to drive more traffic to your website. It’s important you write for sites related to your brand. Reach out to credible blogs, and pitch a guest post idea.

Python Tutorial: A simple Flask App using Redis with Docker Compose.

Docker Compose enables multiple Docker containers to run in a single environment. In this tutorial, we'll write a basic Flask app with Redis using Docker Compose. What is Flask? Flask is a very lightweight framework for developing APIs in Python. For the production purposes, it's recommended to use Flask with uWSGI application server and nginx which is a web server and a reverse proxy. But in this tutorial, we will just create a simple Flask application. What is redis? Redis is a free open source data memory store, used as a database, cache and message broker. Prerequisites: You need to install Docker Engine and Docker Compose.

STEP-1:

Create a project folder on your host machine and enter that directory: $ mkdir project_folder $ cd project_folder

STEP-2:

Create requirements.txt file in the project folder and add the following lines in that file. #project_folder/requirements.txt flask redis

STEP-3:

Create app.py file in the project folder and add the following lines. #project_folder/app.py import Flask and Redis libraries from flask import Flask from redis import Redis import random app = Flask(name) redis = Redis(host='redis', port=6379) # declare main route @app.route('/') def main(): return 'Hi. In order to earn bonus points enter your name in the url. eg: /John' # declare a route that gets the visitor's name. Every name has its own bonus points. @app.route('/') def greet(name): bonus = random.randrange(1, 100) redis.incrby(name, bonus) return 'Hello %s. You have earned %d bonus points. Your total point is %s.' % (name, bonus, redis.get(name)) # run the flask application on the local development server. if name == "main": app.run(host="0.0.0.0", debug=True)

STEP-4:

Create Dockerfile in the project_folder and add the following: FROM python:latest ADD . /app WORKDIR /app RUN pip3 install -r requirements.txt CMD python3 app.py

STEP-5:

Create docker-compose.yml in the project_folder and define the services. There will be two services named app and redis.The app service builds the custom image from the Dockerfile in the project folder which is the current directory.Container’s exposed port (5000) is mapped to the port 5000 on the host.The current directory is mapped to the working directory "/app" folder inside the container.This service depends on redis service. The redis service uses the latest Redis image from Docker Hub. version: '3' services: app: build: . ports: - "5000:5000" volumes: - .:/app depends_on: - redis redis: image: redis

STEP-6:

Build and Run with Docker Compose Start the application from your directory: $ docker-compose up

STEP-7:

You can test the app on your browser with http://localhost:5000. Second, visit http://localhost:5000/username You can try different usernames. Each username will have different bonus points thanks to redis.

STEP-8:

You can stop the application with CTRL+C. And then stop the container. $ docker-compose stop

STEP-9

Troubleshooting: If you make some changes and the changes don't apply, remove the built images and rebuild them. docker-compose rm -f docker-compose pull docker-compose up --build Further Reading: - Unix/ Linux Bash Shell Scripting. - How to use “amazon-linux-extras” and install a package on AWS EC2 running Amazon Linux 2? - How to remember Linux commands?

It can be said that taking care of little dents and dings on a vehicle is a simple matter. It may not require much time, work, and effort at all, even on a car’s metal and plastic parts. We will talk about the situations that you may face.

When the paint has flaked or has been scratched off the surface: Before start to prime and paint the car, get rid of any rust, dents or dings, that are found. By taking care of all these things firstly, you can then put a last coat of paint on all of them together and have a vehicle that looks wonderful. When a metal surface has been pushed in and hasn’t been so badly creased:

You can use a rubber plunger to try to pop it back into place. (the kind they call a plumber’s helper). Just wet the edge of the rubber, put the plunger over or near the dent, establish suction by pushing down on equipment’s handle, and then gently pull it toward you. Maybe you need a couple of tries before the surface pops back to normal shape. While you are making the pulling process bright the surface as possible as in order to get the most correct smooth surface. It works especially well on large expanses of a metal surface, such as fenders or doors. The kind of metal does not matter, the final is the same both for aluminum and steel.
