Full Stack Developer Interview Questions and Answers

Landing a Full Stack Developer course in pune role requires a thorough understanding of both front-end and back-end technologies. Preparing well for interviews is key to success. This blog will cover 10 essential Full Stack Developer interview questions and answers to help you ace your next interview, especially if you've trained with SyntaxLevelUp.

1. What is Full Stack Development?

Answer: Full Stack Developer course in pune refers to the ability to develop both client-side (front-end) and server-side (back-end) applications. It requires proficiency in technologies like HTML, CSS, and JavaScript on the front-end, as well as server-side frameworks like Node.js, Django, or Ruby on Rails.

2. Can you explain the difference between SQL and NoSQL databases?

Answer: SQL databases are relational and store data in tables with predefined schemas, while NoSQL databases are non-relational and store data in flexible formats like key-value pairs, documents, or graphs. SQL databases (like MySQL, PostgreSQL) are best for structured data, while NoSQL (like MongoDB) excels with unstructured data and scalability is a full stack developer course in pune.

3. What are RESTful APIs and how do they work?

Answer: RESTful APIs are web services that adhere to REST architecture principles, allowing for communication between the client and server. They use HTTP methods like GET, POST, PUT, and DELETE to perform CRUD (Create, Read, Update, Delete) operations on resources, usually represented as JSON data.

4. How do you ensure the security of a web application?

Answer: I ensure security by implementing measures such as HTTPS, data encryption, user authentication via OAuth or JWT, and protection against vulnerabilities like SQL injection and cross-site scripting (XSS). Additionally, I follow secure coding practices and regularly audit the code for any security gaps.

5. Explain MVC architecture in full stack development.

Answer: MVC stands for Model-View-Controller. The Model represents the data and business logic, the View is the user interface, and the Controller handles input from the user and updates both the Model and the View. This pattern ensures a clean separation of concerns, making code more modular and easier to maintain.

6. What are the differences between front-end and back-end development?

Answer: Front-end development focuses on the user interface and experience, using HTML, CSS, and JavaScript to create the visual part of a web application. Back-end development deals with server-side logic, databases, and APIs, using languages like Python, Node.js, or Java, handling data storage, and ensuring smooth communication between the client and server.

7. What is asynchronous programming and how is it implemented in JavaScript?

Answer: Asynchronous programming allows multiple tasks to run independently, without blocking the main execution thread. In JavaScript, this is implemented using callbacks, promises, and async/await. This ensures that long-running operations (like network requests) don't block the rest of the code from executing.

8. How do you manage version control in full stack projects?

Answer: I use Git for version control, employing a branching strategy (like GitFlow) to organize development. I commit frequently with clear messages and use pull requests for code reviews, ensuring collaboration and maintaining code quality. Tools like GitHub and GitLab help manage repositories and automate workflows.

9. How do you optimize a web application's performance?

Answer: I optimize performance by minimizing HTTP requests, using code splitting, lazy loading, and compressing assets like images and CSS/JavaScript files. On the back-end, I ensure optimized database queries, caching, and use load balancers to handle traffic efficiently.

10. Describe your experience working in Agile development.

Answer: In Agile environments, I collaborate with cross-functional teams, participating in daily stand-ups, sprint planning, and retrospectives. I use tools like JIRA or Trello to manage tasks and ensure continuous feedback and delivery. Agile allows for flexibility in development, with iterative progress and regular client feedback.

PHP Form MySQL

To check if MySQL is running: mysql.server status

To start MySQL: mysql.server start

Connecting to a MySQL database

(new-connection.php)

This PHP code is a set of functions for interacting with a MySQL database. Let's break down what each part does:

Connection Process:

Constants (DB_HOST, DB_USER, DB_PASS, DB_DATABASE) are defined to hold the database connection information. These constants should be adjusted to match the database settings.

A new mysqli object is created to establish a connection to the MySQL database using the defined constants.

If the connection fails, an error message is displayed, and the script stops executing.

Database Querying Functions:

fetch_all($query): This function executes a SELECT query that may return multiple rows. It fetches all the rows as associative arrays and stores them in an array. The array of rows is then returned.

fetch_record($query): This function executes a SELECT query that is expected to return a single row. It fetches that single row as an associative array and returns it.

run_mysql_query($query): This function is used to execute INSERT, DELETE, or UPDATE queries. It returns the ID of the most recently inserted record (if applicable) or true/false based on the success of the query.

escape_this_string($string): This function is used to escape special characters in a string, making it safe to use in database queries. This helps prevent SQL injection attacks. It returns the escaped string.

Overall, these functions provide a convenient and secure way to interact with a MySQL database in PHP scripts. They encapsulate common database operations and help prevent SQL injection vulnerabilities by properly escaping user input.

Include and Require

Let's say you have two files: new-connection.php and index.php. New-connection php has the Database blueprint where you're creating an object to connect to the MySql database. Now if you want to gain access or use this inside index.php, how do you do it? Use include and require. In this case, since the new-connection.php is NECESSARY inside index.php so that it will have a connection to the database, use require. But if you have another php file that you want to add to index.php but not really necessary, just use include. When you use require but there's an error in the inserted file, it will produce an error and it will HALT the execution. If you use include and there's an error in the include part, it will display the error but will still CONTINUE executing the rest of the file.

So, if new-connection.php contains essential code for index.php to function correctly (like setting up a database connection), you should use require to include it, ensuring that if the file is missing or fails to include, the script execution stops, preventing potential errors further down the line due to the missing functionality. For other files that are not essential for the core functionality of index.php, you can use include. If these files are missing, it won't halt the script execution, and your script can continue running without them.

What if you forgot you already included or required a file?

We can just use require_once() and include_once() instead of just require() and include(). These functions will ignore the duplicated calls.

Connection Errors

There can be multiple possible errors when connecting to a mysql database. Check the DB_HOST, the root, or the pass. When I encountered an unknown database error, all I had to do was to go to phpmyadmin and imported the database.

Sample Folder Structure

new-connection.php (database connection)

home.php (contains HTML + require('new-connection.php');

In home.php, to check if database has been sucessfully connected, do a var_dump($connection)

Accessing and Displaying Database Records

fetch_all($query), fetch_record($query), etc, will return an associative array containing details of a record/records from the database. To access a specific detail, we can just access it like how we access multidimensional associative arrays.

$query = "SELECT * FROM people WHERE id = 1";

$person = fetch_record($query);

$fetch_record() will return an associative array that contains the details of a record. Example.

array(5) { ["id"]=>string(1) "1" ["first_name"]=>string(5) "Hanna" ["last_name"]=>string(9) "Velazquez" ["from"]=>string(19) "2014-09-23 12:19:25" ["to"]=>string(19) "2014-11-20 12:19:32" }

since this associative array is stored in $person, we can now access details of this record inside the HTML by doing:

<?php echo $person['first_name']; ?>

INSERT, UPDATE, DELETE a record

If we want to insert, update, or delete a record, use run_mysql_query($query). If successful, it will return the id of the newly added record OR true or false if it was a success or not.

$query = "INSERT INTO people(first_name,last_name) VALUES ('Jon', 'SNOW')"; if(run_mysql_query($query)){ echo "added"; }else{ echo "failed"; }

Excel, Word, Access, Outlook

Previously on computer literacy: A Test For Computer Literacy

If you’re a computer programmer, you sometimes hear other programmers complain about Excel, because it mixes data and code, or about Word, because it mixes text and formatting, and nobody ever uses Word and Excel properly.

If you’re a computer programmer, you frequently hear UX experts praise the way Excel allows non-programmers to write whole applications without help from the IT department. Excel is a great tool for normal people and power users, I often hear.

I have never seen anybody who wasn’t already versed in a real programming language write a complex application in an Excel spreadsheet. I have never seen anybody who was not a programmer or trained in Excel fill in a spreadsheet and send it back correctly.

Computer programmers complain about the inaccessibility of Excel, the lack of discoverability, the mixing of code and data in documents that makes versioning applications a proper nightmare, the influence of the cell structure on code structure, and the destructive automatic casting of cell data into datatypes.

UX experts praise Excel for giving power to non-programmers, but I never met a non-programmer who used Excel “properly”, never mind developed an application in it. I met non-programmers who used SPSS, Mathematica, or Matlab properly a handful of times, but even these people are getting rarer and rarer in the age of Julia, NumPy, SymPy, Octave, and R. Myself, I have actually had to learn how to use Excel in school, in seventh grade. I suspect that half of the “basic computer usage” curriculum was the result of a lobbying campaign by Microsoft’s German branch, because we had to learn about certain features in Word, Excel, and PowerPoint on Windows 95, and non-Microsoft applications were conspicuously absent.

Visual Basic and VBS seemed like a natural choice to give power to end users in the 90s. People who had already used a home computer during the 8-bit/16-bit era (or even an IBM-compatible PC) were familiar with BASIC because that was how end-users were originally supposed to interact with their computers. BASIC was for end users, and machine code/compiled languages were for “real programmers” - BASIC was documented in the manual that came with your home computer, machine code was documented in MOS data sheets. From today’s point of view, programming in BASIC is real programming. Calling Visual Basic or .Net scripting in Excel “not programming“ misrepresents what modern programmers do, and what GUI users have come to expect after the year 2000.

Excel is not very intuitive or beginner-friendly. The “basic computer usage” curriculum was scrapped shortly after I took it, so I had many opportunities to observe people who were two years younger than me try to use Excel by experimenting with the GUI alone.

The same goes fro Microsoft Word. A friend of mine insists that nobody ever uses Word properly, because Word can do ligatures and good typesetting now, as well as footnotes, chapters, outline note taking, and so on. You just need to configure it right. If people used Word properly, they wouldn’t need LaTeX or Markdown. That friend is already a programmer. All the people I know who use Word use WYSIWYG text styling, fonts, alignment, tables, that sort of thing. In order to use Word “properly“, you’d have to use footnotes, chapter marks, and style sheets. The most “power user” thing I have ever seen an end user do was when my father bought a CD in 1995 with 300 Word templates for all sorts of occasions - birthday party invitation, employee of the month certificate, marathon completion certificate, time table, cooking recipe, invoice, cover letter - to fill in and print out.

Unlike Excel, nobody even claims that non-programmer end users do great things in Word. Word is almost never the right program when you have email, calendars, wikis, to-do lists/Kanban/note taking, DTP, vector graphics, mind mapping/outline editors, programmer’s plain text editors, dedicated novelist/screenwriting software, and typesetting/document preparation systems like LaTeX. Nobody disputes that plain text, a wiki, or a virtual Kanban board is often preferable to a .doc or .docx file in a shared folder. Word is still ubiquitous, but so are browsers.

Word is not seen as a liberating tool that enables end-user computing, but as a program you need to have but rarely use, except when you write a letter you have to print out, or when you need to collaborate with people who insist on e-mailing documents back and forth.

I never met an end user who actually liked Outlook enough to use it for personal correspondence. It was always mandated by an institution or an employer, maintained by an IT department, and they either provided training or assumed you already had had training. Outlook has all these features, but neither IT departments nor end users seemed to like them. Outlook is top-down mandated legibility and uniformity.

Lastly, there is Microsoft Access. Sometimes people confused Excel and Access because both have tables, so at some point Microsoft caved in and made Excel understand SQL queries, but Excel is still not a database. Access is a database product, designed to compete with products like dBase, Cornerstone, and FileMaker. It has an integrated editor for the database schema and a GUI builder to create forms and reports. It is not a networked database, but it can be used to run SQL queries on a local database, and multiple users can open the same database file if it is on a shared SMB folder. It is not something you can pick up on one afternoon to code your company’s billing and invoicing system. You could probably use it to catalogue your Funko-Pop collection, or to keep track of the inventory, lending and book returns of a municipal library, as long as the database is only kept on one computer. As soon as you want to manage a mobile library or multiple branches, you would have to ditch Access for a real SQL RDBMS.

Microsoft Access was marketed as a tool for end-user computing, but nobody really believed it. To me, Access was SQL with training wheels in computer science class, before we graduated to MySQL and then later to Postgres and DB2. UX experts never tout Access as a big success story in end-user computing - yet they do so for Excel.

The narrative around Excel is quite different from the narrative around Yahoo Pipes, IFTTT, AppleScript, HyperCard, Processing, or LabView. The narrative goes like this: “Excel empowers users in big, bureaucratic organisations, and allows them to write limited applications to solve business problems, and share them with co-workers.”

Excel is not a good tool for finance, simulations, genetics, or psychology research, but it is most likely installed on every PC in your organisation already. You’re not allowed to share .exe files, but you are allowed to share spreadsheets. Excel is an exchange format for applications. Excel files are not centrally controlled, like Outlook servers or ERP systems, and they are not legible to management. Excel is ubiquitous. Excel is a ubiquitous runtime and development environment that allows end-users to create small applications to perform simple calculations for their jobs.

Excel is a tool for office workers to write applications to calculate things, but not without programming, but without involving the IT department. The IT department would like all forms to be running on some central platform, all data to be in the data warehouse/OLAP platform/ERP system - not because they want to make the data legible and accessible, but because they want to minimise the number of business-critical machines and points of failure, because important applications should either run on servers in a server rack, or be distributed to workstations by IT.

Management wants all knowledge to be formalised so the next guy can pick up where you left off when you quit. For this reason, wikis, slack, tickets and kanban boards are preferable to Word documents in shared folders. The IT department calls end-user computing “rogue servers“ or “shadow IT“. They want all IT to have version control, unit tests, backups, monitoring, and a handbook. Accounting/controlling thinks end-user computing is a compliance nightmare. They want all software to be documented, secured, and budgeted for. Upper management wants all IT to be run by the IT department, and all information integrated into their reporting solution that generates these colourful graphs. Middle management wants their people to get some work done.

Somebody somewhere in the C-suite is always viewing IT as a cost centre, trying to fire IT people and to scale down the server room. This looks great on paper, because the savings in servers, admins, and tech support are externalised to other departments in the form of increased paperwork, time wasted on help hotlines, and

Excel is dominating end-user computing because of social reasons and workplace politics. Excel is not dominating end-user computing because it is actually easy to pick up for end-users.

Excel is dominating end-user computing neither because it is actually easy to pick up for non-programmers nor easy to use for end-users.

This is rather obvious to all the people who teach human-computer interaction at universities, to the people who write books about usability, and the people who work in IT departments. Maybe it is not quite as obvious to people who use Excel. Excel is not easy to use. It’s not obvious when you read a book on human-computer interaction (HCI), industrial design, or user experience (UX). Excel is always used as the go-to example of end-user computing, an example of a tool that “empowers users”. If you read between the lines, you know that the experts know that Excel is not actually a good role model you should try to emulate.

Excel is often called a “no code“ tool to make “small applications“, but that is also not true. “No Code” tools usually require users to write code, but they use point-and-click, drag-and-drop, natural language programming, or connecting boxes by drawing lines to avoid the syntax of programming languages. Excel avoids complex syntax by breaking everything up into small cells. Excel avoids iteration or recursion by letting users copy-paste formulas into cells and filling formulas in adjacent cells automatically. Excel does not have a debugger, but shows you intermediate results by showing the numbers/values in the cells by default, and the code in the cells only if you click.

All this makes Excel more like GameMaker or ClickTeam Fusion than like Twine. Excel is a tool that doesn’t scare users away with text editors, but that’s not why people use it. It that were the reason, we would be writing business tools and productivity software in GameMaker.

The next time you read or hear about the amazing usability of Excel, take it with a grain of salt! It’s just barely usable enough.

How to Extract Product Data from Walmart with Python and BeautifulSoup

Walmart is the leading retailer with both online stores as well as physical stores around the world. Having a larger product variety in the portfolio with $519.93 Billion of net sales, Walmart is dominating the retail market as well as it also provides ample data, which could be utilized to get insights on product portfolios, customer’s behavior, as well as market trends.

In this tutorial blog, we will extract product data from Walmart s well as store that in the SQL databases. We use Python for scraping a website. The package used for the scraping exercise is called BeautifulSoup. Together with that, we have also utilized Selenium as it helps us interact with Google Chrome.

Scrape Walmart Product Data

The initial step is importing all the required libraries. When, we import the packages, let’s start by setting the scraper’s flow. For modularizing the code, we initially investigated the URL structure of Walmart product pages. A URL is an address of a web page, which a user refers to as well as can be utilized for uniquely identifying the page.

Here, in the given example, we have made a listing of page URLs within Walmart’s electronics department. We also have made the list of names of different product categories. We would use them in future to name the tables or datasets.

You may add as well as remove the subcategories for all major product categories. All you require to do is going to subcategory pages as well as scrape the page URL. The address is general for all the available products on the page. You may also do that for maximum product categories. In the given image, we have showed categories including Toys and Food for the demo.

In addition, we have also stored URLs in the list because it makes data processing in Python much easier. When, we have all the lists ready, let’s move on for writing a scraper.

Also, we have made a loop for automating the extraction exercise. Although, we can run that for only one category as well as subcategory also. Let us pretend, we wish to extract data for only one sub-category like TVs in ‘Electronics’ category. Later on, we will exhibit how to scale a code for all the sub-categories.

Here, a variable pg=1 makes sure that we are extracting data for merely the first URL within an array ‘url_sets’ i.e. merely for the initial subcategory in main category. When you complete that, the following step might be to outline total product pages that you would wish to open for scraping data from. To do this, we are extracting data from the best 10 pages.

Then, we loop through a complete length of top_n array i.e. 10 times for opening the product pages as well as scrape a complete webpage structure in HTML form code. It is like inspecting different elements of web page as well as copying the resultants’ HTML code. Although, we have more added a limitation that only a part of HTML structure, which lies in a tag ‘Body’ is scraped as well as stored as the object. That is because applicable product data is only within a page’s HTML body.

This entity can be used for pulling relevant product data for different products, which were listed on an active page. For doing that, we have identified that a tag having product data is the ‘div’ tag having a class, ‘search-result-gridview-item-wrapper’. Therefore, in next step, we have used a find_all function for scraping all the occurrences from the given class. We have stored this data in the temporary object named ‘codelist’.

After that, we have built the URL of separate products. For doing so, we have observed that different product pages begin with a basic string called ‘https://walmart.com/ip’. All unique-identifies were added only before this string. A unique identifier was similar as a string values scraped from a ‘search-result-gridview-item-wrapper’ items saved above. Therefore, in the following step, we have looped through a temporary object code list, for constructing complete URL of any particular product’ page.

With this URL, we will be able to scrape particular product-level data. To do this demo, we have got details like unique Product codes, Product’s name, Product page URL, Product_description, name of current page’s category where a product is positioned, name of the active subcategory where the product is positioned on a website (which is called active breadcrumb), Product pricing, ratings (Star ratings), number of reviews or ratings for a product as well as other products suggested on the Walmart’s site similar or associated to a product. You may customize this listing according to your convinience.

The code given above follows the following step of opening an individual product page, based on the constructed URLs as well as scraping the products’ attributes, as given in the listing above. When you are okay with a listing of attributes getting pulled within a code, the last step for a scraper might be to attach all the product data in the subcategory within a single frame data. The code here shows that.

A data frame called ‘df’ would have all the data for products on the best 10 pages of a chosen subcategory within your code. You may either write data on the CSV files or distribute it to the SQL database. In case, you need to export that to the MySQL database within the table named ‘product_info’, you may utilize the code given below:

You would need to provide the SQL database credentials and when you do it, Python helps you to openly connect the working environment with the database as well as push the dataset straight as the SQL dataset. In the above code, in case the table having that name exists already, the recent code would replace with the present table. You may always change a script to evade doing so. Python provides you an option to 'fail', 'append', or 'replace' data here.

It is the basic code structure, which can be improved to add exclusions to deal with missing data or later loading pages. In case, you choose to loop the code for different subcategories, a complete code would look like:

A very important question, how do you choose the best web hosting company from among the hosting companies that host your site if you cannot choose between the offers of hosting companies and you cannot determine which one is most appropriate for your site in this matter, we will be very neutral, we will not recommend hosting for a specific company, but only we will explain what are the foundations Through which you can choose which hosting companies are best and what is best for your site, I hope this topic will help you.

What are the criteria by which you can choose the best hosting company for your site كيف تختار افضل استضافة لموقعك First: an operating system You must first choose between an operating system and there are two types of systems, Windows and Linux This choice depends on the nature and programming of the sites that will be run on the server. When did he choose the Linux operating system? To start with, you should know that Linux is a free, open source operating system Open Source is the best price one. If the sites are working or designed in PHP, HTML and Java and MySQL databases are open source also this is definitely the best. When did he choose the Windows operating system? It is a closed source operating system and users are required to purchase a license from Microsoft and for this reason it is not the best in terms of price. If the sites are working or designed in IIS Web Server and ASP.net languages Microsoft SQL Server databases, you have to use Windows hosting for your site. Aside from these points, there is no other difference. Both support the rest of the programming languages ​​regarding protection, as they are only due to the hosting company’s ability to protect. Second: storage space This element is very important if your site contains images, files and databases of large sizes and you intend to add many articles and continue to develop the archiving of the site, it is preferable to search for the largest areas. Third: data transfer The transfer of data, or what is known as traffic, is also a very important element if you hope for your site with an increasing number of visitors or an increased interaction with your site without any stopping the site. Fourth: Domains hosted If you are looking to create a new site in the future, be sure to choose a service that allows you to host more than one domain, in order to avoid looking for another company and pay more than one hosting space. In that element, Arab companies allow one domain to host them, but international companies allow an unlimited number of domains. Fifth: The number of available e-mail accounts E-mail is considered one of the most popular internet services and used in your domain. There are companies that allow the creation of an unlimited number of postal accounts so be sure to take this into account when choosing to host. Sixth: The number of databases Nobody hides the importance of hosting a suitable number of databases in order to allow the creation of any independent database for the site, such as a forum, chat, magazine, file upload, or any interactive script related to the site. Therefore, you must verify the number of databases available within the hosting by asking before contracting.

Seventh: retrieving the pickup This element is extremely important, therefore you must make sure of the periods and ways in which the backup is taken for your site in order to retrieve it in the case of deleting files by mistake or hacking problems at any time and in order not to have to create the site again, but it can be retrieved the last back up to the latest date before the occurrence The problem is to avoid losing topics and posts that may affect the archiving of the site. Eighth: Technical support service This point is very important and many researchers for hosting companies do not notice it. We must ask about work times and how to communicate in the event of any problem with the site related to hosting. Therefore, you must search for the company that provides technical support service 24 hours a day during the whole year in order to avoid a problem or stop the site and wait for a response to you from the company at the working time and may be on a company holiday. The best way to communicate with companies is through a ticket system that allows you to follow the problem and prove your right in the event of a late response or irrational responses from the support employee.

Ninth: The possibility of recovering the amount This element is important to ensure the credibility of the company. You must ensure that the company is certified and reliable. Often companies give 30 days for a refund, and some give 90 days, but this is rare

Most twofold appropriations of Python send with Tk, a standard GUI lib. It gives you a chance to draft a UI for applications. Aside from that, some toolboxs thR are accessible are:

·         wxWidgets

·         Kivy – for composing multitouch applications

·         Qt by means of pyqt or pyside

·         We likewise have some stage explicit toolboxs:

·         GTK+

·         Microsoft Foundation Classes through the win32 augmentations

·         Delphi

3. Logical and Numeric Applications

It is anything but an unexpected that python discovers its place in established researchers. For this, we have:

·         SciPy – An accumulation of bundles for arithmetic, science, and designing.

·         Pandas - An Data investigation and - displaying library

·         IPython – An incredible shell for simple altering and recording of work sessions. It likewise bolsters perceptions and parallel processing.

·         Programming Carpentry Course – It shows essential abilities for logical figuring and running bootcamps. It likewise gives open-get to educating materials.

Additionally, NumPy gives us a chance to manage complex numerical counts.

4. Programming Development Application

Programming engineers use python as a help language. They use it to construct control and the executives, testing, and for some different things:

·         SCons – for manufacture control

·         Buildbot, Apache Gump – for computerized and nonstop assemblage and testing

·         Gathering, Trac – for undertaking the board and bug-following.

·         List of Integrated Development Environments

5. Python Applications in Education

On account of its effortlessness, quickness, and substantial network, Python makes for a marvelous early on programming language. It's an extraordinary language to educate in schools or even learn alone.

Pursue my record to peruse my standard answers on Data Science

6. Python Applications in Business

Python is additionally an extraordinary decision for creating ERP and internet business frameworks:

·         Tryton – A three-level, abnormal state broadly useful application stage.

·         Odoo – An administration programming with a scope of business applications. With all that, it's an all-rounder and structures a total suite of big business the board applications basically.

7. Database Access

With Python, you have:

·         Custom and ODBC interfaces to MySQL, Oracle, PostgreSQL, MS SQL Server, and others. These are unreservedly accessible for download.

·         Article databases like Durus and ZODB

·         Standard Database API

8. System Programming

With each one of those potential outcomes, how might Python slack in system programming? It provides support for lower-level system programming:

·         Contorted Python – A system for offbeat system programming. We referenced it in area 2.

·         A simple to-utilize attachment interface

9. Diversions and 3D Graphics

This one is the most intriguing. When individuals hear somebody state they're learning Python, the principal thing they get asked is – 'All in all, did you make any diversion yet?'

PyGame, PyKyra are two structures for amusement advancement with Python. Aside from these, we additionally get an assortment of 3D-rendering libraries.

In case you're one of those diversion engineers, you can look at PyWeek, a semi-yearly amusement programming challenge.

10. Other Python Applications

These are a portion of the significant Python use cases. Aside from what we just talked about, regardless it discovers use in more places:

·         Support based Applications

·         Sound – or Video-based Applications

·         Applications for Images

·         Endeavor Applications

·         3D CAD Applications

·         PC Vision (Facilities like face-discovery and shading location)

·         Computer Vision

·         Machine learning

·         Web Scraping (Harvesting Data from sites)

·         Scripting

·         Artificial intelligence

·         Data Analysis

Python is simply all over.

Tumblr's 4th Annual Security Capture the Flag

We've hosted an internal Security Capture the Flag (CTF) event for four years in a row now, with each year getting better than the last!

The event

Previously, we were only open to Tumblr employees. This year we decided to extend an invite out to the other teams housed under our parent company, Oath.

All participants had a three hour window to hack, a buffet of tacos, beer, and wine to dive into, and a stack of prizes for the top four players (see Prizes below for details)!

Challenges were available Jeopardy-style, broken down by category. We had eight fun categories to select from:

Auth Bypass (authn | authz)

Cross Site Request Forgery (CSRF)

Cross Site Scripting (XSS)

Crypto

Forensics

Reverse Engineering

SQL Injection (SQLi)

XML Injection (+ XXE)

We also sprinkled a few "inside joke" Easter eggs around the system that awarded bonus points to anyone that discovered them! For example, if they attempted to find a hole in the CTF system itself and navigated to /wp-admin, we'd give them a flag on a prank WordPress page; or perhaps testing to find XSS with a <marquee> tag — only the greatest of all XSS tags!

While the Security Team walked around and helped out, we also setup a mini lockpick village just because.

Solving challenges & scoring points

To complete a challenge, the player had to achieve the goal within one of the listed categories.

In XSS challenges, the player would need to cause the browser to create an alert dialog (e.g. alert()).

Conversely, in SQL Injection challenges the player would need to read the flag column from the flags table in that challenge's database.

When the player successfully solved the challenge they were awarded with a flag, each in the format ofTumblr{s0mE_cHalL3nGe_j0kE-abcdef012}. That last piece is a unique hash for the user, per challenge, so that they couldn't directly share their flag. They can help others — even provide the solution — but they can't simply give away their flag.

Each challenge, when solved, is worth a certain number of points based on the challenge's difficulty and whether or not the player used the challenge's hints.

There were 3800 points available, though no player was able to break 1000!

At the end, we locked the leaderboard and announced the winners.

Prizes

We awarded the top four players based on their ranking on the leaderboard. First place got first dibs from the list. Second place gets to select theirs from the remaining lot, and so on.

Up for grabs this year:

Hak5 Elite Field Kit

Proxmark3 RDV2 Kit

Samsung Chromebook Plus

Lockpick set and a "how to" manual

Challenge snapshot

Throughout the eight categories we had a total of 46 challenges. We wanted to have a wide range of challenges that welcomed players of all backgrounds and experience levels.

The goal for XSS challenges was to get an alert dialog to appear. The player is presented with a vulnerable web page and they needed to determine where the vulnerability is and how to exploit it. Example:

These challenge levels ranged everywhere between simple non-sanitized output to DOM reflection to CSP bypasses.

One fo the more unique challenges to develop was SQL Injection. These offered players the ability to put their SQL skills to the test with a variety of basic input injection, blind injection, and filter bypassing challenges.

In at least one of the SQLi challenges, players had to inject into an INSERT statement. When creating challenges like this, special care had to be taken to give players the full capabilities of MySQL but also prevent them from revealing the flag to other players — it's a tricky thing making vulnerabilities secure!

The infrastructure

A frequent question I receive when I talk about deving on the CTF is "are you using CTFd?" Short answer? Nope! A slightly less short answer is that CTFd wasn't out when we started this =P.

The framework we're using is called "Security Training Grounds" and it's a custom-written project using PHP, PhantomJS, and MySQL (with HTML + JavaScript too, of course), running in Amazon Web Services.

An advantage of writing this in-house was that it gave us the ability to create a dynamic and robust system that has endless capabilities.

PHP + MySQL

The website was created from scratch, written in PHP with a little bit of jQuery + Bootstrap on the frontend and MySQL as the database.

The big thing here are the challenges themselves. Each challenge is hosted on its own subdomain. This enables us to provide live and interactive challenges like XSS or SQLi while still providing support static challenge types like Crypto or Reverse Engineering.

We accomplished this by allowing dynamic hostnames on the webserver and defining a subdomain hostname for each challenge that's stored in MySQL. When a web request comes in, the app checks whether it's a subdomain or not. If so, it hits the database to determine what to display.

For most challenges, we were able to handle all of the dynamic pieces directly in PHP. For some, such as the C or Java reverse engineering challenges, we did need to shell out to gcc or javac to build the custom binaries for each user.

PhantomJS

A difficulty for XSS and CSRF challenges is determining whether or not the participant successfully exploited the system. Surely we don't want to manually confirm for each flag, and attempting to pattern-match on their input would be crazy.

Our solution: execute what the player submits!

This is my own little baby, a piece of the system I'm so excited by. See, what better way to test XSS than to actually test XSS. As mentioned in the "Challenge snapshot" section above, when a player is working on a XSS challenge, they are given a website that has a XSS vulnerability. Their goal is to make an alert dialog appear. This is key and the requirement of the XSS framework itself.

On the client, we use this fancy little snippet:

var ctf_alert = alert; alert = function(msg) {    ctf_phantomjs_alert_test(document.location, msg); };

This overrides the window's actual alert() function and lets us put some processing logic in the middle. The logic is to take a snapshot of the current page - the URL, query string, POST parameters, the cookies and then pass the full snapshot to a backend PhantomJS service (via a PHP proxy, to help prevent tampering).

The PhantomJS service replicates that entire request and loads the target web page. If the page invokes an alert() call, which we catch via PhantomJS's onAlert, then we return with a "success" and the PHP proxy will return the user's flag. Our alert() overriding logic will then replace whatever message the user attempted to display and display their flag instead. Fancy af.

CSRF has a similar setup, except the player needs to submit their full CSRF payload:

After submitting the payload to the PHP proxy, we pass the payload to PhantomJS. This executes the payload in the context of an empty web page. If the PhantomJS worker successfully falls victim to the targeted action, the PHP proxy will return a flag to the user!

Open source

The framework code, as-is, is still relatively hacky and written with internal dependencies. We do believe in OSS though! We expect a near-future initiative to rewrite portions of it so we can release it for others to use for their CTF events, too.

p3p headers were a pain, but no experience installaing apache or maintaining server software, I had c-panel and that was my power limit.

#Paintboard java code#

As for my coding practices and scripts are a few years behind, back to php 4 since I last coded, and maintained all code on my old site, I rarely wrote anything that was too complicated, the most being dealing with SSL certificates, custom.

#Paintboard java mods#

Im not sure what you mean by "up to date", do you mean the server software versions as shipped from the factory they are not up to date? My host managed all that before, they would routinely do updates to php and the mods, and it sometimes crashed the site, I would usually have to tweak the scripts effected, but as far as installing mods the host did that.

#Paintboard java upgrade#

(The TS-112P comes with 512MB DDR3 RAM, the older ( discontinued) TS-112 only came with 256MB DDRII RAM) You can not upgrade the RAM on any of QNAP's ARM-based models like the TS-112 an TS-112P, so purchasing the right NAS model at the time of purchase is important. Your needs do indeed seem quite minimal, but your needs may change over time, so I urge you to check out what these devices are capable of, before purchasing such a low-end model.

#Paintboard java manual#

Have you reviewed the QNAP Turbo NAS User Manual and QNAP App Center to see everything these devices are capable of? I outgrew my 1-Bay NAS in a matter of weeks once I became familiar with it, so I eventually sold it to a friend, and purchased a 4-Bay model instead. How many concurrent users do you expect your Web Server to support? I purchased my first NAS to be a LAMP Server too, but soon found myself using about 85% of it's capabilities. A TS-112 will do this, but I would urge you to purchase a NAS with more RAM, and preferably at least 2 Bays, so that you can protect your data and Apache/PHP configuration by RAID protection. The versions provided are not up to date, so depending on your Website code, this could become a challenge for you. Will a TS112 do it? All presently available QNAP NAS devices support Apache, MySQL and PHP. My biggest question is, does all of the Qnap NAS' ( such as the entry level TS112 ) have the WebServer features? will they all run SQL, PHP? In reality that's all I need of it, is just a few php scripts such as contact us and help pages in php, and everything else across the network can be handled by other devices, so it can be basically dedicated to light traffic and serve only a few PHP scripts, and maintain the SQL databases.

With that in mind, a multi-core proc (4 cores or more) should be able to handle SAM with all features turned on.įOR USE WITH FIREBIRD DATABASE (written by a previous maintainer, kept for archive): prefer mysqlĢ. I did switch to a dual core and but still the average load was higher than acceptable levels so I decided to leave all statistics relays turned off and implemented a third party solution of my own to capture my stats. I had to disable statistic relays to bring down the CPU usage to an acceptable level for single core proc. I originally tested on a single core dedicated box, however resource usage was high and the system was unstable. I was unable to install gecko or msxml3 (as the instructions on winehq state are necessary), However I was still able to install and run SAM without them. I have not tested everything, but I have had no show stopping issues for anything I've tested. All the essential features: Playback, Encoding/Streaming, Relay Statistics, DSPs, FX, Playlist, Mysql connections (remote and local), PAL Script Execution, Playlist Rotation, Remote requests.
