[aspectpriority]

after some faffing about today i've gotten Tavros, Gamzee, and Kanaya's quirks all working just fine. these were a little harder because you can't just find and replace characters, which is how I've been doing it so far - you have to flip through the string and check what actually needs capitalising.

We've found a couple different examples for this sorta thing, one used character arrays and another used string builders - i'm not sure if one is better than the other? This kinda thing often bugs us a lot - we like to do things the "proper" way, but frankly, for what this is (a silly little baby's first java project) it literally doesn't Fucking matter. Maybe we'll get good enough to give a damn at some point? but for the time being, especially for something that no one Else is going to use, it's pretty inconsequential.

That said! we've got everyone from Aradia through to Terezi done now. Just over half way through! Isn't that neat!

The so-called Department of Government Efficiency (DOGE) is starting to put together a team to migrate the Social Security Administration’s (SSA) computer systems entirely off one of its oldest programming languages in a matter of months, potentially putting the integrity of the system—and the benefits on which tens of millions of Americans rely—at risk.

The project is being organized by Elon Musk lieutenant Steve Davis, multiple sources who were not given permission to talk to the media tell WIRED, and aims to migrate all SSA systems off COBOL, one of the first common business-oriented programming languages, and onto a more modern replacement like Java within a scheduled tight timeframe of a few months.

Under any circumstances, a migration of this size and scale would be a massive undertaking, experts tell WIRED, but the expedited deadline runs the risk of obstructing payments to the more than 65 million people in the US currently receiving Social Security benefits.

“Of course, one of the big risks is not underpayment or overpayment per se; [it’s also] not paying someone at all and not knowing about it. The invisible errors and omissions,” an SSA technologist tells WIRED.

The Social Security Administration did not immediately reply to WIRED’s request for comment.

SSA has been under increasing scrutiny from president Donald Trump’s administration. In February, Musk took aim at SSA, falsely claiming that the agency was rife with fraud. Specifically, Musk pointed to data he allegedly pulled from the system that showed 150-year-olds in the US were receiving benefits, something that isn’t actually happening. Over the last few weeks, following significant cuts to the agency by DOGE, SSA has suffered frequent website crashes and long wait times over the phone, The Washington Post reported this week.

This proposed migration isn’t the first time SSA has tried to move away from COBOL: In 2017, SSA announced a plan to receive hundreds of millions in funding to replace its core systems. The agency predicted that it would take around five years to modernize these systems. Because of the coronavirus pandemic in 2020, the agency pivoted away from this work to focus on more public-facing projects.

Like many legacy government IT systems, SSA systems contain code written in COBOL, a programming language created in part in the 1950s by computing pioneer Grace Hopper. The Defense Department essentially pressured private industry to use COBOL soon after its creation, spurring widespread adoption and making it one of the most widely used languages for mainframes, or computer systems that process and store large amounts of data quickly, by the 1970s. (At least one DOD-related website praising Hopper's accomplishments is no longer active, likely following the Trump administration’s DEI purge of military acknowledgements.)

As recently as 2016, SSA’s infrastructure contained more than 60 million lines of code written in COBOL, with millions more written in other legacy coding languages, the agency’s Office of the Inspector General found. In fact, SSA’s core programmatic systems and architecture haven’t been “substantially” updated since the 1980s when the agency developed its own database system called MADAM, or the Master Data Access Method, which was written in COBOL and Assembler, according to SSA’s 2017 modernization plan.

SSA’s core “logic” is also written largely in COBOL. This is the code that issues social security numbers, manages payments, and even calculates the total amount beneficiaries should receive for different services, a former senior SSA technologist who worked in the office of the chief information officer says. Even minor changes could result in cascading failures across programs.

“If you weren't worried about a whole bunch of people not getting benefits or getting the wrong benefits, or getting the wrong entitlements, or having to wait ages, then sure go ahead,” says Dan Hon, principal of Very Little Gravitas, a technology strategy consultancy that helps government modernize services, about completing such a migration in a short timeframe.

It’s unclear when exactly the code migration would start. A recent document circulated amongst SSA staff laying out the agency’s priorities through May does not mention it, instead naming other priorities like terminating “non-essential contracts” and adopting artificial intelligence to “augment” administrative and technical writing.

Earlier this month, WIRED reported that at least 10 DOGE operatives were currently working within SSA, including a number of young and inexperienced engineers like Luke Farritor and Ethan Shaotran. At the time, sources told WIRED that the DOGE operatives would focus on how people identify themselves to access their benefits online.

Sources within SSA expect the project to begin in earnest once DOGE identifies and marks remaining beneficiaries as deceased and connecting disparate agency databases. In a Thursday morning court filing, an affidavit from SSA acting administrator Leland Dudek said that at least two DOGE operatives are currently working on a project formally called the “Are You Alive Project,” targeting what these operatives believe to be improper payments and fraud within the agency’s system by calling individual beneficiaries. The agency is currently battling for sweeping access to SSA’s systems in court to finish this work. (Again, 150-year-olds are not collecting social security benefits. That specific age was likely a quirk of COBOL. It doesn’t include a date type, so dates are often coded to a specific reference point—May 20, 1875, the date of an international standards-setting conference held in Paris, known as the Convention du Mètre.)

In order to migrate all COBOL code into a more modern language within a few months, DOGE would likely need to employ some form of generative artificial intelligence to help translate the millions of lines of code, sources tell WIRED. “DOGE thinks if they can say they got rid of all the COBOL in months, then their way is the right way, and we all just suck for not breaking shit,” says the SSA technologist.

DOGE would also need to develop tests to ensure the new system’s outputs match the previous one. It would be difficult to resolve all of the possible edge cases over the course of several years, let alone months, adds the SSA technologist.

“This is an environment that is held together with bail wire and duct tape,” the former senior SSA technologist working in the office of the chief information officer tells WIRED. “The leaders need to understand that they’re dealing with a house of cards or Jenga. If they start pulling pieces out, which they’ve already stated they’re doing, things can break.”

Understanding Java Data Types: A Comprehensive Guide

Java, one of the most widely used programming languages, is known for its portability, security, and rich set of features. At the core of Java programming are data types, which define the nature of data that can be stored and manipulated within a program. Understanding data types is crucial for effective programming, as they determine how data is stored, how much memory it occupies, and the operations that can be performed on that data.

What are Data Types?

In programming, data types specify the type of data that a variable can hold. They provide a way to classify data into different categories based on their characteristics and operations. Java categorizes data types into two main groups:

1. Primitive Data Types

2. Reference Data Types

Why Use Data Types?

1. Memory Management: Different data types require different amounts of memory. By choosing the appropriate data type, you can optimize memory usage, which is particularly important in resource-constrained environments.

2. Type Safety: Using data types helps catch errors at compile time, reducing runtime errors. Java is a statically typed language, meaning that type checks are performed during compilation.

3. Code Clarity: Specifying data types makes the code more readable and understandable. It allows other developers (or your future self) to quickly grasp the intended use of variables.

4. Performance Optimization: Certain data types can enhance performance, especially when dealing with large datasets or intensive calculations. For example, using int instead of long can speed up operations when the range of int is sufficient.

5. Defining Operations: Different data types support different operations. For example, you cannot perform mathematical operations on a String data type without converting it to a numeric type.

When and Where to Use Data Types?

1. Choosing Primitive Data Types:

Use int when you need a whole number without a decimal, such as counting items.

Use double for fractional numbers where precision is essential, like financial calculations.

Use char when you need to store a single character, such as a letter or symbol.

Use boolean when you need to represent true/false conditions, like in conditional statements.

2. Choosing Reference Data Types:

Use String for any textual data, such as names, messages, or file paths.

Use Arrays when you need to store multiple values of the same type, such as a list of scores or names.

Use Custom Classes to represent complex data structures that include multiple properties and behaviors. For example, a Car class can encapsulate attributes like model, year, and methods for actions like starting or stopping the car.

1. Primitive Data Types

Primitive data types are the most basic data types built into the Java language. They serve as the building blocks for data manipulation in Java. There are eight primitive data types:

Examples of Primitive Data Types

1. Byte Example

byte age = 25; System.out.println(“Age: ” + age);

2. Short Example

short temperature = -5; System.out.println(“Temperature: ” + temperature);

3. Int Example

int population = 1000000; System.out.println(“Population: ” + population);

4. Long Example

long distanceToMoon = 384400000L; // in meters System.out.println(“Distance to Moon: ” + distanceToMoon);

5. Float Example

float pi = 3.14f; System.out.println(“Value of Pi: ” + pi);

6. Double Example

double gravitationalConstant = 9.81; // m/s^2 System.out.println(“Gravitational Constant: ” + gravitationalConstant);

7. Char Example

char initial = ‘J’; System.out.println(“Initial: ” + initial);

8. Boolean Example

boolean isJavaFun = true; System.out.println(“Is Java Fun? ” + isJavaFun);

2. Reference Data Types

Reference data types, unlike primitive data types, refer to objects and are created using classes. Reference data types are not defined by a fixed size; they can store complex data structures such as arrays, strings, and user-defined classes. The most common reference data types include:

Strings: A sequence of characters.

Arrays: A collection of similar data types.

Classes: User-defined data types.

Examples of Reference Data Types

1. String Example

String greeting = “Hello, World!”; System.out.println(greeting);

2. Array Example

int[] numbers = {1, 2, 3, 4, 5}; System.out.println(“First Number: ” + numbers[0]);

3. Class Example

class Car {     String model;     int year;

    Car(String m, int y) {         model = m;         year = y;     } }

public class Main {     public static void main(String[] args) {         Car car1 = new Car(“Toyota”, 2020);         System.out.println(“Car Model: ” + car1.model + “, Year: ” + car1.year);     } }

Type Conversion

In Java, type conversion refers to converting a variable from one data type to another. This can happen in two ways:

1. Widening Conversion: Automatically converting a smaller data type to a larger data type (e.g., int to long). This is done implicitly by the Java compiler.

int num = 100; long longNum = num; // Widening conversion

2. Narrowing Conversion: Manually converting a larger data type to a smaller data type (e.g., double to int). This requires explicit casting.

double decimalNum = 9.99; int intNum = (int) decimalNum; // Narrowing conversion

Conclusion

Understanding data types in Java is fundamental for effective programming. It not only helps in managing memory but also enables programmers to manipulate data efficiently. Java’s robust type system, consisting of both primitive and reference data types, provides flexibility and efficiency in application development. By carefully selecting data types, developers can optimize performance, ensure type safety, and maintain code clarity.

By mastering data types, you’ll greatly enhance your ability to write efficient, reliable, and maintainable Java programs, setting a strong foundation for your journey as a Java developer.

Date manipulation is required in everyday Java programming. Creating a date instance for a past or future date is required at many places where we are trying to have a date range. I have seen many developers keep searching on google about "how to add or subtract days in java.util.Date". or "how to calculate 7 days date past or future from present date in core java" My previous post about date utility methods used setTime() method of Date object for getting the back date. After doing some more reading I realized that this can be done in a much easier manner by using java.util.Calendar.add() method. Good thing about this method is the static final constants provided by java.util.Calendar class itself. This gives more flexibility in manipulating the date with all levels of constants. Calendar.SECOND Calendar.MINUTE Calendar.HOUR Calendar.DATE Calendar.MONTH Calendar.YEAR Below are the example methods which uses Calendar.add method with these constants. This demonstrates how we can get a past of future date for any time we are looking for(Seconds, minutes,hours, days,months or years) /** * Get the date java.util.Date object for days before current date * * @param days * @return */ public static Date getDateBeforeDays(int days) Calendar cal = Calendar.getInstance(); cal.add(Calendar.DATE, -days); // -days return cal.getTime(); /** * Get the date java.util.Date object for days after current date * * @param days * @return */ public static Date getDateAfterDays(int days) Calendar cal = Calendar.getInstance(); cal.add(Calendar.DATE, days); // +days return cal.getTime(); /** * Get the date java.util.Date object for years after current date * * @param years * @return */ public static Date getDateAfterYears(int years) Calendar cal = Calendar.getInstance(); cal.add(Calendar.YEAR, years); // +years return cal.getTime(); /** * Get the date java.util.Date object for years before current date * * @param years * @return */ public static Date getDateBeforeYears(int years) Calendar cal = Calendar.getInstance(); cal.add(Calendar.YEAR, -years); // -years return cal.getTime(); /** * Get the date java.util.Date object for months after current date * * @param months * @return */ public static Date getDateAfterMonths(int months) Calendar cal = Calendar.getInstance(); cal.add(Calendar.MONTH, months); // +months return cal.getTime(); /** * Get the date java.util.Date object for months before current date * * @param months * @return */ public static Date getDateBeforeMonths(int months) Calendar cal = Calendar.getInstance(); cal.add(Calendar.MONTH, -months); // -months return cal.getTime(); /** * Get the date java.util.Date object for hours before current date * * @param hours * @return */ public static Date getDateBeforeHours(int hours) Calendar cal = Calendar.getInstance(); cal.add(Calendar.HOUR, -hours); // -hours return cal.getTime(); /** * Get the date java.util.Date object for hours after current date * * @param hours * @return */ public static Date getDateAfterHours(int hours) Calendar cal = Calendar.getInstance(); cal.add(Calendar.HOUR, hours); // +hours return cal.getTime(); /** * Get the date java.util.Date object for minutes before current date * * @param minutes * @return */ public static Date getDateBeforeMinutes(int minutes) Calendar cal = Calendar.getInstance(); cal.add(Calendar.MINUTE, -minutes); // -minutes return cal.getTime(); /** * Get the date java.util.Date object for minutes after current date * * @param minutes * @return */ public static Date getDateAfterMinutes(int minutes) Calendar cal = Calendar.getInstance(); cal.add(Calendar.MINUTE, minutes); // +minutes return cal.getTime(); /** * Get the date java.util.Date object for seconds before current date * * @param seconds * @return */ public static Date getDateBeforeSeconds(int seconds) Calendar cal = Calendar.getInstance(); cal.add(Calendar.SECOND, -seconds); // -seconds return cal.getTime(); /** * Get the date java.util.Date object for seconds after current date

* * @param seconds * @return */ public static Date getDateAfterSeconds(int seconds) Calendar cal = Calendar.getInstance(); cal.add(Calendar.SECOND, seconds); // +seconds return cal.getTime(); The java.util.Date class has been deprecated since Java 1.1 and has been replaced by the java.time package since Java 8. The java.time package introduced a new set of classes that provide more functionality and better handling of date and time operations, such as LocalDate, LocalTime, and LocalDateTime. It is recommended to use these new classes instead of the deprecated java.util.Date class for date and time operations. Here is another example to get instance of specific date in java.

Coding Brushup for Java #10: Best Practices & Tips

In the fast-evolving world of software development, writing clean, efficient, and maintainable code is paramount. For Java developers, adhering to best practices not only enhances code quality but also ensures scalability and ease of collaboration. This guide delves into essential Java coding best practices, offering actionable insights to elevate your programming standards.

1. Embrace Meaningful Naming Conventions

Clear and descriptive names for classes, methods, and variables significantly improve code readability and maintainability. Avoid ambiguous names like temp or data; instead, opt for names that convey purpose, such as calculate Total Price or user Age. Consistent naming conventions also facilitate smoother collaboration among developers.

2. Adhere to the DRY Principle (Don't Repeat Yourself)

Repetition in code leads to redundancy and increases the risk of errors. By creating reusable methods or classes, you can eliminate duplicate code, making your codebase more concise and easier to maintain. For instance, instead of duplicating validation logic across multiple methods, centralize it in a single utility class. ​

3. Implement the Single Responsibility Principle (SRP)

Each class should have one reason to change, meaning it should only have one job or responsibility. By ensuring that classes are focused on a single task, you enhance code clarity and make it easier to modify or extend functionality without unintended side effects. ​

4. Utilize Exception Handling Wisely

Proper exception handling is crucial for building robust applications. Avoid using exceptions for control flow; instead, catch specific exceptions and handle them appropriately. Employ try-with-resources statements to manage resources like file streams, ensuring they are closed automatically. ​

5. Leverage Java Streams and Lambda Expressions

Introduced in Java 8, Streams and Lambda expressions allow for more concise and readable code, especially when dealing with collections. They enable functional-style operations like filtering, mapping, and reducing, which can simplify complex data processing tasks. ​

6. Prioritize Code Readability

Code is often read more frequently than it's written. Therefore, prioritize readability by using consistent indentation, meaningful comments, and clear logic. Avoid deep nesting and complex conditionals; instead, break down complex methods into smaller, more manageable ones. ​

7. Follow the SOLID Principles

The SOLID principles are a set of five design principles that promote object-oriented design and programming:​

Single Responsibility Principle (SRP): A class should have one, and only one, reason to change.​

Open/Closed Principle (OCP): Software entities should be open for extension but closed for modification.​

Liskov Substitution Principle (LSP): Objects of a superclass should be replaceable with objects of its subclasses without affecting the correctness of the program.​

Interface Segregation Principle (ISP): No client should be forced to depend on methods it does not use.​

Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules. Both should depend on abstractions.​

Adhering to these principles leads to more modular, flexible, and maintainable code. ​

9. Optimize Performance Thoughtfully

While it's important to write efficient code, premature optimization can lead to unnecessary complexity. Focus on writing clear and correct code first; then, profile and optimize performance-critical sections as needed. Utilize tools like JProfiler or Visual VM to identify bottlenecks in your application.​

Conclusion

By integrating these best practices into your Java development workflow, you can produce code that is clean, efficient, and maintainable. Remember, the goal is not just to write code that works, but to write code that is easy to understand, modify, and extend. Continuous learning and adherence to these principles will set you on the path to becoming a proficient Java developer.​
