HEY i read your rambles on the authority skilltober drawing and i just wanna say that id love to read your thoughts on authority and volition's dynamic!! if you want to share them obviously lmao
hi anon!!! you sent this in 6 weeks ago, I am so sorry :( hopefully you still see this
I am! extremely excited to dump about these two!! just needed to have the time/energy to and then it took forever hgkjh
it's gonna be long so putting a break here :) but there are quote screenshots *and* doodles under the cut
first off, a bunch of this stuff is in this post about them, this Volition skilltober post, and this Authority skilltober post, but now it's all together. so if you've seen some of this commentary or screenshots before... that's why
so ... going to sort this into canon and headcanons.
CANON:
we get: all volition and authority interactions I can find!
them agreeing:
Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media
them disagreeing:
Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media
this ones not really agreeing or disagreeing ig:
Tumblr media
this one, the authority passive only fires if volition's doesn't. they're covering for eachotherrr.
Tumblr media
I ran a very complicated SQL query to find all the instances of them having dialogue right after another, but it doesn't account for when the dialogue is separated by a variable check (eg. the sorry cop dialogue needs to check if you have the sorry cop thought). so I did what anyone would do and spent 3 hours making a far more convoluted query to iterate through the variable chains until they reached another line of dialogue. Which for some reason was a lot more easy in theory than in execution. And every time I messed it up it would sit for like 15 minutes and then bomb my computer with 10 million rows of dialogue. And sure, maybe twice I accidentally made it trace through every single dialogue path possible in the game recursively which. required killing it because it blew up. but it eventually WORKED and that's what matters.
So these quotes! Basically. They agree on stuff plenty, backing eachother up against bad ideas presented by Harry, other skills, or other people. but they also bicker a lot, trying to shut down eachother's ideas. Volition is the voice of reason in a lot of these, mostly just his desire not to die out of sheer willpower, as well as shutting down a few of Authority's more impulsive suggestions. But there is one where Volition disagrees with Authority, telling you to keep pushing on the stickbug issue despite the fact that he's only doing it to be stubborn and is actively making the situation worse... I think Authority helps balance against the extreme stubbornness Volition sometimes takes too far.
Here are a couple of them referring to eachother's specialties...
Tumblr media Tumblr media
Authority is also extremely anti narcotics and encourages you to do the right thing (like declining Evrart's bribe) which I'm sure Volition would be happy with, until Authority takes it too far and encourages you to drink and smoke more because it's better than narcotics, and starts encouraging you to basically fabricate situations where you can pretend to be honourable for karma coupons. Which. Sigh.
That's them! They're on the same page and everything is going great right up until it's not.
Also Authority triggers the only instance of healing *all* morale damage in the whole game... :)
Of note is also when Volition *doesn't* chime in. Volition is well aware of the gun idea during the Hardies fail, even before you are, and makes no move to stop it. (Also, the back and forth during that fail when Volition tells you to give the gun back is. hgkh. I can't think of any other instance of Volition trying to override some bad decision and the skill in question talking/fighting back. If it does happen, it must be pretty rare.) He also doesn't stop you during the Authority fail dancing in the church, just urges you to go apologize after the damage is done (despite stopping you from making a racist comment during an encyclopedia fail a different time).
They also do take over for eachother from time to time! Especially with Kim asserting his authority, both of them do it several times. Authority obviously has the eyebrow standoff, but the check to not wipe coal off your face is an Authority check. The check to refuse to drink water after you faint is Volition, as well as Volition will allow you to tell Kim you don't need to be supervised.
HEADCANONS:
YES behold. my headcanons about them.
skill parents... the two of them are the ones all the other skills go to if they need help, or to break up a fight, or to hide from if they're being irresponsible
Tumblr media
one sided rivalry!! volition just wants to keep everything together and authority took that personally. he's far more invested in asserting himself over volition than the other way around -- volition just wants authority to listen to him. we've got volition at 10 skill points and authority at 8, and authority is cooperative right up until Harry takes too much morale damage and volition's points dip below authority's, and then all bets are off.
Tumblr media
ouh I love these two. when they get along, they work together wonderfully and do a great job running the ship together. and when they don't it turns into a mess! :) they absolutely fight over who has to (or gets to, depending) resolve an issue when something comes up while they're fighting. or will defer to the other one if they're separate (go talk to authority > go ask volition loop)
Authority is like this absolute force of nature that can't stand being told no, or anything or anyone getting in his way, and will use intimidation or force or whatever he has to to get his way. And Volition is this wall of willpower that will completely dig his heels in at the first sign of anyone trying to force him to do something he doesn't want to do, and continue to be unrelentingly stubborn about it until the bitter end. Unstoppable force vs immovable object. Authority's desire to control everything is only matched by Volition's desire for control over himself. Like I am not convinced Volition would be able to put self preservation above his stubbornness. And it's this eternal standoff until something (either of their skill points dropping/raising) changes the playing field. They're awful for each other sometimes but they're the only ones who can balance each other out a bit. I'm so normal about them.
I will say with regards to my morale critical volition, which I have many thoughts about constantly... that authority is so much more attuned to volition's strength relative to his own that he often realizes way before the others that morale is getting low. :) may make some mini comics about them because writing is much more fickle... and I like drawing them.
okay... that's far more than anyone could have possibly wanted about these two idiots, I think. hope u enjoyed anon, ty for asking about them!!!

Why Tableau is Essential in Data Science: Transforming Raw Data into Insights
Tumblr media
Data science is all about turning raw data into valuable insights. But numbers and statistics alone don’t tell the full story—they need to be visualized to make sense. That’s where Tableau comes in.
Tableau is a powerful tool that helps data scientists, analysts, and businesses see and understand data better. It simplifies complex datasets, making them interactive and easy to interpret. But with so many tools available, why is Tableau a must-have for data science? Let’s explore.
1. The Importance of Data Visualization in Data Science
Imagine you’re working with millions of data points from customer purchases, social media interactions, or financial transactions. Analyzing raw numbers manually would be overwhelming.
That’s why visualization is crucial in data science:
Identifies trends and patterns – Instead of sifting through spreadsheets, you can quickly spot trends in a visual format.
Makes complex data understandable – Graphs, heatmaps, and dashboards simplify the interpretation of large datasets.
Enhances decision-making – Stakeholders can easily grasp insights and make data-driven decisions faster.
Saves time and effort – Instead of writing lengthy reports, an interactive dashboard tells the story in seconds.
Without tools like Tableau, data science would be limited to experts who can code and run statistical models. With Tableau, insights become accessible to everyone—from data scientists to business executives.
2. Why Tableau Stands Out in Data Science
A. User-Friendly and Requires No Coding
One of the biggest advantages of Tableau is its drag-and-drop interface. Unlike Python or R, which require programming skills, Tableau allows users to create visualizations without writing a single line of code.
Even if you’re a beginner, you can:
✅ Upload data from multiple sources
✅ Create interactive dashboards in minutes
✅ Share insights with teams easily
This no-code approach makes Tableau ideal for both technical and non-technical professionals in data science.
B. Handles Large Datasets Efficiently
Data scientists often work with massive datasets—whether it’s financial transactions, customer behavior, or healthcare records. Traditional tools like Excel struggle with large volumes of data.
Tableau, on the other hand:
Can process millions of rows without slowing down
Optimizes performance using advanced data engine technology
Supports real-time data streaming for up-to-date analysis
This makes it a go-to tool for businesses that need fast, data-driven insights.
C. Connects with Multiple Data Sources
A major challenge in data science is bringing together data from different platforms. Tableau seamlessly integrates with a variety of sources, including:
Databases: MySQL, PostgreSQL, Microsoft SQL Server
Cloud platforms: AWS, Google BigQuery, Snowflake
Spreadsheets and APIs: Excel, Google Sheets, web-based data sources
This flexibility allows data scientists to combine datasets from multiple sources without needing complex SQL queries or scripts.
D. Real-Time Data Analysis
Industries like finance, healthcare, and e-commerce rely on real-time data to make quick decisions. Tableau’s live data connection allows users to:
Track stock market trends as they happen
Monitor website traffic and customer interactions in real time
Detect fraudulent transactions instantly
Instead of waiting for reports to be generated manually, Tableau delivers insights as events unfold.
E. Advanced Analytics Without Complexity
While Tableau is known for its visualizations, it also supports advanced analytics. You can:
Forecast trends based on historical data
Perform clustering and segmentation to identify patterns
Integrate with Python and R for machine learning and predictive modeling
This means data scientists can combine deep analytics with intuitive visualization, making Tableau a versatile tool.
3. How Tableau Helps Data Scientists in Real Life
Tableau has been adopted by the majority of industries to make data science more impactful and accessible. This is applied in the following real-life scenarios:
A. Analytics for Health Care
Tableau is deployed by hospitals and research institutions for the following purposes:
Monitor patient recovery rates and predict outbreaks of diseases
Analyze hospital occupancy and resource allocation
Identify trends in patient demographics and treatment results
B. Finance and Banking
Banks and investment firms rely on Tableau for the following purposes:
✅ Detect fraud by analyzing transaction patterns
✅ Track stock market fluctuations and make informed investment decisions
✅ Assess credit risk and loan performance
C. Marketing and Customer Insights
Companies use Tableau to:
✅ Track customer buying behavior and personalize recommendations
✅ Analyze social media engagement and campaign effectiveness
✅ Optimize ad spend by identifying high-performing channels
D. Retail and Supply Chain Management
Retailers leverage Tableau to:
✅ Forecast product demand and adjust inventory levels
✅ Identify regional sales trends and adjust marketing strategies
✅ Optimize supply chain logistics and reduce delivery delays
These applications show why Tableau is a must-have for data-driven decision-making.
4. Tableau vs. Other Data Visualization Tools
There are many visualization tools available, but Tableau consistently ranks as one of the best. Here’s why:
Tableau vs. Excel – Excel struggles with big data and lacks interactivity; Tableau handles large datasets effortlessly.
Tableau vs. Power BI – Power BI is great for Microsoft users, but Tableau offers more flexibility across different data sources.
Tableau vs. Python (Matplotlib, Seaborn) – Python libraries require coding skills, while Tableau simplifies visualization for all users.
This makes Tableau the go-to tool for both beginners and experienced professionals in data science.
5. Conclusion
Tableau has become an essential tool in data science because it simplifies data visualization, handles large datasets, and integrates seamlessly with various data sources. It enables professionals to analyze, interpret, and present data interactively, making insights accessible to everyone—from data scientists to business leaders.
If you’re looking to build a strong foundation in data science, learning Tableau is a smart career move. Many data science courses now include Tableau as a key skill, as companies increasingly demand professionals who can transform raw data into meaningful insights.
In a world where data is the driving force behind decision-making, Tableau ensures that the insights you uncover are not just accurate—but also clear, impactful, and easy to act upon.

How to Prevent
Tumblr media
Preventing injection requires keeping data separate from commands and queries:
The preferred option is to use a safe API, which avoids using the interpreter entirely, provides a parameterized interface, or migrates to Object Relational Mapping Tools (ORMs). Note: Even when parameterized, stored procedures can still introduce SQL injection if PL/SQL or T-SQL concatenates queries and data or executes hostile data with EXECUTE IMMEDIATE or exec().
Use positive server-side input validation. This is not a complete defense as many applications require special characters, such as text areas or APIs for mobile applications.
For any residual dynamic queries, escape special characters using the specific escape syntax for that interpreter. (escaping technique) Note: SQL structures such as table names, column names, and so on cannot be escaped, and thus user-supplied structure names are dangerous. This is a common issue in report-writing software.
Use LIMIT and other SQL controls within queries to prevent mass disclosure of records in case of SQL injection.
bonus question: think about how query on the image above should look like? answer will be in the comment section

Protect Your Laravel APIs: Common Vulnerabilities and Fixes
API Vulnerabilities in Laravel: What You Need to Know
As web applications evolve, securing APIs becomes a critical aspect of overall cybersecurity. Laravel, being one of the most popular PHP frameworks, provides many features to help developers create robust APIs. However, like any software, APIs in Laravel are susceptible to certain vulnerabilities that can leave your system open to attack.
Tumblr media
In this blog post, we’ll explore common API vulnerabilities in Laravel and how you can address them, using practical coding examples. Additionally, we’ll introduce our free Website Security Scanner tool, which can help you assess and protect your web applications.
Common API Vulnerabilities in Laravel
Laravel APIs, like any other API, can suffer from common security vulnerabilities if not properly secured. Some of these vulnerabilities include:
>> SQL Injection SQL injection attacks occur when an attacker is able to manipulate an SQL query to execute arbitrary code. If a Laravel API fails to properly sanitize user inputs, this type of vulnerability can be exploited.
Example Vulnerability:
$user = DB::select("SELECT * FROM users WHERE username = '" . $request->input('username') . "'");
Solution: Laravel’s query builder automatically escapes parameters, preventing SQL injection. Use the query builder or Eloquent ORM like this:
$user = DB::table('users')->where('username', $request->input('username'))->first();
>> Cross-Site Scripting (XSS) XSS attacks happen when an attacker injects malicious scripts into web pages, which can then be executed in the browser of a user who views the page.
Example Vulnerability:
return response()->json(['message' => $request->input('message')]);
Solution: Always sanitize user input and escape any dynamic content. Laravel provides built-in XSS protection by escaping data before rendering it in views:
return response()->json(['message' => e($request->input('message'))]);
>> Improper Authentication and Authorization Without proper authentication, unauthorized users may gain access to sensitive data. Similarly, improper authorization can allow unauthorized users to perform actions they shouldn't be able to.
Example Vulnerability:
Route::post('update-profile', 'UserController@updateProfile');
Solution: Always use Laravel’s built-in authentication middleware to protect sensitive routes:
Route::middleware('auth:api')->post('update-profile', 'UserController@updateProfile');
>> Insecure API Endpoints Exposing too many endpoints or sensitive data can create a security risk. It’s important to limit access to API routes and use proper HTTP methods for each action.
Example Vulnerability:
Route::get('user-details', 'UserController@getUserDetails');
Solution: Restrict sensitive routes to authenticated users and use proper HTTP methods like GET, POST, PUT, and DELETE:
Route::middleware('auth:api')->get('user-details', 'UserController@getUserDetails');
How to Use Our Free Website Security Checker Tool
If you're unsure about the security posture of your Laravel API or any other web application, we offer a free Website Security Checker tool. This tool allows you to perform an automatic security scan on your website to detect vulnerabilities, including API security flaws.
Step 1: Visit our free Website Security Checker at https://free.pentesttesting.com. Step 2: Enter your website URL and click "Start Test". Step 3: Review the comprehensive vulnerability assessment report to identify areas that need attention.
Tumblr media
Screenshot of the free tools webpage where you can access security assessment tools.
Example Report: Vulnerability Assessment
Once the scan is completed, you'll receive a detailed report that highlights any vulnerabilities, such as SQL injection risks, XSS vulnerabilities, and issues with authentication. This will help you take immediate action to secure your API endpoints.
Tumblr media
An example of a vulnerability assessment report generated with our free tool provides insights into possible vulnerabilities.
Conclusion: Strengthen Your API Security Today
API vulnerabilities in Laravel are common, but with the right precautions and coding practices, you can protect your web application. Make sure to always sanitize user input, implement strong authentication mechanisms, and use proper route protection. Additionally, take advantage of our tool to check Website vulnerability to ensure your Laravel APIs remain secure.

Computer Language
Computer languages, also known as programming languages, are formal languages used to communicate instructions to a computer. These instructions are written in a syntax that computers can understand and execute. There are numerous programming languages, each with its own syntax, semantics, and purpose. Here are some of the main types of programming languages:
1.Low-Level Languages:
Machine Language: This is the lowest level of programming language, consisting of binary code (0s and 1s) that directly corresponds to instructions executed by the computer's hardware. It is specific to the computer's architecture.
Assembly Language: Assembly language uses mnemonic codes to represent machine instructions. It is a human-readable form of machine language and closely tied to the computer's hardware architecture
2.High-Level Languages:
Procedural Languages: Procedural languages, such as C, Pascal, and BASIC, focus on defining sequences of steps or procedures to perform tasks. They use constructs like loops, conditionals, and subroutines.
Object-Oriented Languages: Object-oriented languages, like Java, C++, and Python, organize code around objects, which are instances of classes containing data and methods. They emphasize concepts like encapsulation, inheritance, and polymorphism.
Functional Languages: Functional languages, such as Haskell, Lisp, and Erlang, treat computation as the evaluation of mathematical functions. They emphasize immutable data and higher-order functions.
Scripting Languages: Scripting languages, like JavaScript, PHP, and Ruby, are designed for automating tasks, building web applications, and gluing together different software components. They typically have dynamic typing and are interpreted rather than compiled.
Domain-Specific Languages (DSLs): DSLs are specialized languages tailored to a specific domain or problem space. Examples include SQL for database querying, HTML/CSS for web development, and MATLAB for numerical computation.
3.Other Types:
Markup Languages: Markup languages, such as HTML, XML, and Markdown, are used to annotate text with formatting instructions. They are not programming languages in the traditional sense but are essential for structuring and presenting data.
Query Languages: Query languages, like SQL (Structured Query Language), are used to interact with databases by retrieving, manipulating, and managing data.
Constraint Programming Languages: Constraint programming languages, such as Prolog, focus on specifying constraints and relationships among variables to solve combinatorial optimization problems.

Why Power BI Takes the Lead Against SSRS
Tumblr media
In an era where data steers the course of businesses and fuels informed decisions, the choice of a data visualization and reporting tool becomes paramount. Amidst the myriad of options, two stalwarts stand out: Power BI and SSRS (SQL Server Reporting Services). As organizations, including those seeking Power BI training in Gurgaon, strive to extract meaningful insights from their data, the debate about which tool to embrace gains prominence. In this digital age, where data is often referred to as the "new oil," selecting the right tool can make or break a business's competitive edge.
Understanding the Landscape

With its intuitive interface and user-friendly features, Power BI transforms raw data into interactive visuals, making it easier to interpret and draw actionable conclusions.
What is SSRS?
On the other hand, SSRS, also developed by Microsoft, focuses on traditional reporting. It enables the creation, management, and delivery of traditional paginated reports. SSRS has been a reliable choice for years, but the advent of Power BI has brought new dimensions to data analysis.
The Advantages of Power BI Over SSRS
In the realm of data analysis and reporting tools, Power BI shines as a modern marvel, surpassing SSRS in various crucial aspects. Let's explore the advantages that set Power BI apart:
1. Interactive Visualizations
Power BI's forte lies in its ability to transform raw data into interactive and captivating visual representations. Unlike SSRS, which predominantly deals with static reports, Power BI empowers users to explore data dynamically, enabling them to drill down into specifics and gain deeper insights. This interactive approach enhances data comprehension and decision-making processes.
2. Real-time Insights
While SSRS offers a snapshot of data at a particular moment, Power BI steps ahead with real-time data analysis capabilities. Modern businesses, including those enrolling in a Power BI training institute in Bangalore, require up-to-the-minute insights to stay competitive, and Power BI caters precisely to this need. It connects seamlessly to various data sources, ensuring that decisions are based on the latest information.
3. User-Friendly Interface
Power BI's intuitive interface stands in stark contrast to SSRS's somewhat technical setup. With its drag-and-drop functionality, Power BI eliminates the need for extensive coding knowledge. This accessibility allows a wider range of users, from business analysts to executives, to create and customize reports without depending heavily on IT departments.
4. Scalability
As a company grows, so does the amount of data it handles. Power BI's cloud-based architecture ensures scalability without compromising performance. Whether you're dealing with a small dataset or handling enterprise-level data, Power BI can handle the load, guaranteeing smooth operations and robust analysis.
5. Natural Language Queries
One of Power BI's standout features is its ability to understand natural language queries. Users can interact with the tool using everyday language and receive relevant visualizations in response. This bridge between human language and data analytics simplifies the process for non-technical users, making insights accessible to all.
The SEO Advantage
In the digital age, search engine optimization (SEO) plays a vital role in ensuring your content, including information about Power BI training in Mumbai, reaches the right audience. When it comes to comparing Power BI and SSRS in terms of SEO, Power BI once again takes the lead.
With their interactive visual content, Power BI-enhanced articles attract more engagement. This higher engagement leads to longer on-page time, lower bounce rates, and improved SEO rankings. Search engines recognize user behavior as a marker of content quality and relevance, boosting the visibility of Power BI-related articles.

SQLi Potential Mitigation Measures
Tumblr media
Phase: Architecture and Design
Strategy: Libraries or Frameworks
Use a vetted library or framework that prevents this weakness or makes it easier to avoid. For example, persistence layers like Hibernate or Enterprise Java Beans can offer protection against SQL injection when used correctly.
Phase: Architecture and Design
Strategy: Parameterization
Use structured mechanisms that enforce separation between data and code, such as prepared statements, parameterized queries, or stored procedures. Avoid constructing and executing query strings with "exec" to prevent SQL injection [REF-867].
Phases: Architecture and Design; Operation
Strategy: Environment Hardening
Run your code with the minimum privileges necessary for the task [REF-76]. Limit user privileges to prevent unauthorized access if an attack occurs, such as by ensuring database applications don’t run as an administrator.
Phase: Architecture and Design
Duplicate client-side security checks on the server to avoid CWE-602. Attackers can bypass client checks by altering values or removing checks entirely, making server-side validation essential.
Phase: Implementation
Strategy: Output Encoding
Avoid dynamically generating query strings, code, or commands that mix control and data. If unavoidable, use strict allowlists, escape/filter characters, and quote arguments to mitigate risks like SQL injection (CWE-88).
Phase: Implementation
Strategy: Input Validation
Assume all input is malicious. Use strict input validation with allowlists for specifications and reject non-conforming inputs. For SQL queries, limit characters based on parameter expectations for attack prevention.
Phase: Architecture and Design
Strategy: Enforcement by Conversion
For limited sets of acceptable inputs, map fixed values like numeric IDs to filenames or URLs, rejecting anything outside the known set.
Phase: Implementation
Ensure error messages reveal only necessary details, avoiding cryptic language or excessive information. Store sensitive error details in logs but be cautious with content visible to users to prevent revealing internal states.
Phase: Operation
Strategy: Firewall
Use an application firewall to detect attacks against weaknesses in cases where the code can’t be fixed. Firewalls offer defense in depth, though they may require customization and won’t cover all input vectors.
Phases: Operation; Implementation
Strategy: Environment Hardening
In PHP, avoid using register_globals to prevent weaknesses like CWE-95 and CWE-621. Avoid emulating this feature to reduce risks. source
