Join a Country Club Mod

Hello! Unfortunately, Rock Ridge Country Club has closed down due to financial mismanagement and embezzlement. However, your sims now can join an even better club: Cedar Creek Country Club!

I’m excited to announce that I’ve completely reworked the Country Club mod from scratch. This mod holds a special place in my heart as it was the first one I ever made, and I’m thrilled to present it with improved quality and new features.

If you’ve used my previous Country Club mod, you’ll notice both differences and similarities. So, how does the new mod work? Your sim can apply to become a member of Cedar Creek Country Club. This time, the process is more challenging, with the possibility of rejection, requiring more effort both financially and mentally.

However, the application process is streamlined for a smoother experience. Steps to become a member:

Pay Application Fee: This is a 5000 simoleon nonrefundable fee.

Fill out Application Form

Schedule Interview: Choose between two time slots and attend within 24 hours.

Write Letter of Interest

Submit Reference Letters: Cedar Creek requires two reference letters from current members. Your sim can ask a member directly or post on the Cedar Creek community forums. If a member is interested, they may call and offer to write a reference letter. This method is more challenging.

Attend Information Session (Optional): If you have questions about the club or application process, attend an information session available on weekdays.

• Household Funds

• Fame Level

• Reputation

• Job Type and Level

• Charisma

• Interview Outcome

These elements can greatly increase your chances of getting accepted into the country club.​

Once they become a member and pay the $10,000 initiation fee, your entire household will also gain Cedar Creek membership.

As a Cedar Creek member, there are ongoing fees to pay. You can choose to pay annually (over four weeks) or quarterly (over one week). It’s important to stay on top of these payments to maintain your membership. There are many activities your sim can partake in with family and friends. You can find these options on the computer in the Country Club pie menu.​

Your sim can try to appeal to the country club if they have been rejected, kicked out, or blacklisted. The chances of getting another shot are very low, but high charisma can significantly help.

If they get lucky and are invited to meet with the admissions committee, they have a few hours to attend the meeting and must commit immediately. If they were previously kicked out, they will still need to pay the initiation fee again.

Lot Trait

I have also added a Country Club lot trait with the mod. So as a Cedar Creek member if you don't feel like going to rabbit hole activities you use the country club lot trait and use it on any lot.

I wanted the Country Club lot trait to be customizable, so random members won’t show up automatically; you need to assign members to make it exclusive.

You can assign members by left-shift clicking on the computer and finding the option under the country club pie menu. There are a few social interactions available for different sims at the country club, depending on their roles.

The lot trait is straightforward, but the key is to assign members. You can also remove members using the same method.

Does this mod require any DLC?

No, it does not.

What else do I need for the mod?

Lumpinou's Mood Pack Mod, so it is required for the mod to work properly.

You can get the mod here.

If you already have it great! But make sure it's up to date. Otherwise, it will break the UI

XML injector

I'm experiencing some weird bugs!

Let me know, please.

Report it here: Mod Bug Report

So we built this aacprocessors library. Intention was to read and manipulate any AAC software. Its not ideal but just made a new method just for the grid right now.

def replace_cell_with_xml( self, gridset_path: str, target_caption: Optional[str], target_action: Optional[str], new_content_xml: str, output_path: str, ) -> None: """Replace a cell's content with a new XML fragment across the gridset. Args: gridset_path (str): Path to the original gridset file. target_caption (Optional[str]): Caption of the button to replace. target_action (Optional[str]): Action command of the button to replace. new_content_xml (str): New XML content for the cell. output_path (str): Path to save the modified gridset. """

So search for a action or a cell label and it will replace all buttons tin the gridset with the xml of the button you replace it with.

For a demo see https://gist.github.com/willwade/26a1327c4e130b6afa36977fc129e09b

Really this needs more thought and a way of mking this across all AAC file types. I’m thinking a ‘replace_cell_with_raw’ method for sql or filebased systems. Its quite a bit different for sqlite systems though as they abstract the button logic from the content. Needs more thought

How to Build an API: A Complete 2025 Guide 

As businesses increasingly rely on digital solutions to drive growth, the importance of APIs (Application Programming Interfaces) has skyrocketed. Whether you're building a mobile app, connecting third-party services, or enabling seamless communication between internal systems, APIs play a pivotal role. The process of API creation, however, can be complex, requiring careful planning, robust architecture, and proper testing. In this comprehensive 2025 guide, we'll walk you through the essential steps to building a successful API, and discuss how partnering with an API development company can streamline the process for businesses looking to create top-notch APIs. 

What is an API? 

At its core, an API allows different software applications to communicate with each other. Think of it as a bridge that connects systems, allowing them to exchange data and functionality in real-time. For example, a weather app might use an API to pull data from a weather service, or a payment system might rely on an API to connect to a bank's system to process transactions. APIs serve as the backbone of modern software ecosystems, enabling the exchange of information between diverse services and platforms. 

In today's competitive environment, companies are striving to build APIs that are not only functional but also scalable, secure, and efficient. A well-designed API allows for flexibility, improves the user experience, and promotes faster development and innovation. But how do you build one? Let’s break it down into clear steps. 

Step 1: Understand the Requirements 

Before diving into the technical side, it's crucial to understand the problem your API aims to solve. Start by asking questions like: 

What data or services will your API expose? 

Who will be the consumers of the API? 

What kind of operations will the API support (e.g., CRUD - Create, Read, Update, Delete)? 

What are the performance and security requirements? 

By defining the purpose of your API early on, you can create a more structured and efficient design. Many businesses today rely on API development services to clarify these requirements and ensure their API’s design is well-aligned with their organizational needs. 

Step 2: Plan the API Design 

Once the requirements are clear, the next step is planning the design. The key elements here include: 

Endpoints: These are the specific paths in the API that clients will interact with. For example, an API for a library might have endpoints like /books, /authors, and /categories. 

HTTP Methods: APIs typically rely on standard HTTP methods (GET, POST, PUT, DELETE) to define actions on resources. 

Data Formats: JSON (JavaScript Object Notation) is the most commonly used data format for APIs, though XML is also an option. Choose the format that best fits your use case. 

Authentication and Authorization: Ensuring that only authorized users can access your API is crucial. Common approaches include API keys, OAuth, and JWT (JSON Web Tokens). 

Rate Limiting: To prevent abuse and ensure fair use, you should define rate limits that restrict how many requests can be made to the API in a given time frame. 

Designing a scalable and efficient API requires in-depth knowledge of best practices, and partnering with an experienced API development company can ensure you’re taking the right approach from the start. 

Step 3: Choose the Right API Protocol 

APIs use different protocols to facilitate communication between systems. The two most common protocols are: 

REST (Representational State Transfer): This is the most widely used protocol due to its simplicity, scalability, and stateless nature. REST APIs are ideal for handling large amounts of data and can be consumed easily by clients. 

GraphQL: This newer protocol allows clients to request only the data they need, improving performance and flexibility. It’s especially useful for complex applications with multiple interconnected resources. 

The protocol you choose will depend on your API’s use case, data structure, and performance requirements. 

Step 4: Develop the API 

With the design and protocol in place, it’s time to start coding. During development, you’ll: 

Set up the environment: Choose the programming language and framework that suits your project. Popular languages for API development include Python (with Django or Flask), Node.js (with Express), and Java (with Spring Boot). 

Build the endpoints: Start by creating the necessary routes for each of the endpoints you’ve planned. 

Implement authentication: Integrate the chosen authentication mechanism to ensure secure access. 

Ensure error handling: Make sure your API gracefully handles errors, such as invalid input or failed requests, and provides meaningful error messages. 

If you find API development overwhelming or complex, consider hiring a professional API development company to handle the heavy lifting. These companies have the expertise to build APIs that are reliable, secure, and easy to scale. 

If you're interested in exploring the benefits of API development services for your business, we encourage you to book an appointment with our team of experts. 

Book an Appointment 

Step 5: Test the API 

Testing is a critical step in the API development process. You'll want to ensure that your API works as expected under various conditions. This includes: 

Unit tests: Test individual components of your API. 

Integration tests: Verify that your API works well with other systems and services. 

Load testing: Simulate heavy traffic to ensure your API can handle high volumes of requests without crashing. 

Many companies also opt to involve external testers or use automated testing tools to catch issues that may not be apparent during development. 

Step 6: Document the API 

Good documentation is essential for API adoption and ease of use. Make sure to include: 

Overview: A summary of what the API does and its purpose. 

Endpoint descriptions: Details of each endpoint, including methods, parameters, and responses. 

Error codes: A list of possible error messages and what they mean. 

Examples: Provide sample requests and responses to help users understand how to interact with the API. 

Clear and concise documentation will help developers integrate your API smoothly and quickly. 

Step 7: Monitor and Maintain the API 

Once your API is live, it’s essential to keep track of its performance and resolve any issues that arise. Continuous monitoring allows you to: 

Track usage patterns and potential abuse. 

Identify slow or failing endpoints and optimize them. 

Respond quickly to security vulnerabilities. 

Maintenance also involves updating the API as your business grows or technology evolves, so it's essential to ensure your API remains reliable and secure over time. 

Conclusion 

Building an API is a complex but rewarding process that requires careful planning, strong technical skills, and ongoing maintenance. By following the steps outlined above, you can create an API that meets your business goals and provides a seamless experience for your users. However, if you're new to API development or looking to streamline the process, partnering with a professional API development services provider can significantly improve your chances of success. They can help you design, build, and maintain an API that supports your business growth and innovation.

[ad_1] In a continually evolving take a look at automation subject, accuracy is all the time the important thing to successful. Selenium is the muse of many testing frameworks, making it doable for builders and QA engineers to beat varied challenges inherent to complicated internet purposes. However the essence of each arguments stays the identical: the place internet improvement is regularly growing, the issue of undetectable component identification turns into a critical difficulty. That is the place XPath comes into the image because the potential reply to supply a selenium path to fulfill the accuracy requirement in automation testing. The significance of XPath is immense in terms of boosting the effectivity of checks. Nevertheless, regardless of the promise that XPath holds for scripts, practitioners have cited challenges in terms of embracing and studying its complexities. Among the challenges that appear straightforward to deal with are creating expressions, coping with dynamic components of the net web page, and run-time points. On this weblog publish, we search to decode XPath in Selenium. Understanding XPath XPath, an acronym for XML Path Language, is an expression language that refers to choosing nodes in an XML or HTML doc. This paper goals to elaborate on the function and utilization of XPath in Selenium automation notably as a way that may be successfully utilized in precisely figuring out components of internet pages at the point of interest of the take a look at in the course of the strategy of automated testing. XPath acts as an utility for looking and shifting from node to node concerning the constructions of XML or HTML paperwork. It has a well-defined method of referring to a component relying on its attributes, textual content worth, location, and visibility of different components. XPath makes it doable to filter and choose components as a result of Selenium can not work together with components in an internet web page with out first finding them. Kinds of XPath expressions XPath provides two main varieties of expressions: The route of the preliminary displacement can be both absolute and relative. What makes them completely different from different XPath selectors is that absolute XPath selectors start from the foundation node of the doc and work from there to acquire the selector for the component. Relative XPath expressions, in distinction, begin their path from an absolute context node and subsequently are extra versatile and fewer delicate in direction of adjustments within the doc’s construction. Furthermore, axes and capabilities can also be adopted in XPath expressions to make component choice much more particular. Syntax and construction of XPath expressions XPath expressions use axes, node checks, predicates, and capabilities; Axes specify how one component pertains to one other: the place one component is a dad or mum of one other, or whether or not two components are on the similar degree. Node checks outline to which node set the XPath expression applies; doable node checks embody component names and attributes. Predicates work for eliminating nodes utilizing situations whereas capabilities assist in engaged on the values of nodes or carry out any calculations within the XPath expression. Benefits of utilizing XPath for component choice As for the component choice in Selenium automation, XPath has a number of benefits in comparison with the opposite strategies. Initially, it's claimed to supply a degree of flexibility and reliability in component referencing that permits testers to not redo the entire thing within the case of adjustments within the construction or content material of the doc. The ahead and backward navigation within the doc tree gives XPath an added benefit of making paths for particular complicated components. Equally, utilizing XPath expressions permits narrowing down the take a look at goal to particular components by attributes, textual content material, place,

and different standards, which will be extraordinarily helpful when testing complicated HTML and XML paperwork. In conclusion, XPath permits power-up of Selenium for exact and environment friendly component identification to foster clean and correct automated testing. XPath in Selenium XPath is named one of the crucial primary Selenium options and is extremely correct in addition to versatile component choice methodology. Right here we’re to debate the professionals of utilizing XPath over different locators, areas the place it could possibly shine at its greatest, real-life examples of utilizing XPath and, lastly, efficiency considerations which can be very important for one of the best XPath efficiency. XPath vs. different locators in Selenium XPath units itself as one of many preferable locators in Selenium in contrast to ID, class title, title, tag title, hyperlink textual content locators as it's extra complete and gives extra scope for component identification. Whereas these locators are based mostly on sure attributes or properties of components, XPath is an all-encompassing question language for navigating to components based mostly on just about any parameter one may conceive of, together with attributes, textual content material, order, and relations to different components. It helps testers to have a complete functionality of dealing with sure methods which allow them to fulfill the structural and content material challenges that accompany most internet purposes. Conditions the place XPath excels XPath is greatest utilized in instances the place details about the specified components have to be pinpointed with excessive accuracy, particularly in dynamic internet purposes that will characteristic complicated DOM timber. Its use of the doc tree construction and making use of operations between mother and father and youngsters in addition to when filtering the weather makes it very helpful in dealing with varied instances. It shines in areas like trying to find a component with ids which can be generated dynamically, trying to find DOM components by the textual content content material partially, and discovering a component by its place among the many different components within the DOM. In abstract, XPath helps testers to implement environment friendly methods and options to dealing with varied testing duties. Actual-world examples demonstrating XPath’s effectiveness Through the use of XPath, discovering such nodes shall be very straightforward; for example, contemplate a situation the place an internet type has many enter fields which have related tag names. Locators constructed with XPath enable testers to put in writing situations to focus on a wide range of enter fields by their distinct traits like, placeholder textual content or label textual content, thus, eliminating the likelihood of selecting incorrect components. Likewise, XPath will be additionally used to deal with dynamic components, indicators, or widgets like dropdowns or accordions as it's doable to switch the staking standards of the respective component relying on its state/visibility. It will likely be evident from the examples that XPath is efficient in analyzing the interior construction of the net and in defining correct choice factors when conducting automated testing. Efficiency issues when utilizing XPath in Selenium XPath gives unparalleled flexibility in terms of hint choosing components and that is the principle purpose why this methodology is utilized in Selenium automation; nevertheless, in terms of the efficiency facet, the usage of XPath expression will result in a big slowdown of Selenium automation due to the intensive and inefficient nature of XPath. XPath queries, which can traverse via massive timber or contain use of complicated predicates would additionally include some overhead, rising the take a look at run instances. To cut back efficiency points, the testers ought to guarantee they use optimized XPath expressions inside the

scripts via environment friendly queries, and keep away from or restrict navigation and hierarchy traversal as a lot as they'll and carry out extra particular looking quite than finishing up generalized searches. Additional, administration of values in cache together with sensible ready methods can additional enhance the pace of take a look at executions whereas utilizing XPath in Selenium. Mastering XPath Expressions XPath expressions are elementary for selecting components rightly and successfully on internet purposes via Selenium automation testing frameworks. This phase intends to debate strategies to get most out of XPath by writing acceptable XPath expressions, approaches to put in writing XPath for dynamic internet components, XPath capabilities and axis and writing ideas to enhance XPath expressions for bettering the execution pace of take a look at scripts. Methods for crafting efficient XPath expressions XPath expressions are most effective when just a few normal pointers are adopted; the construction of the doc have to be thought of, very particular and cautious consideration have to be paid to element-attributes, and XPath have to be used selectively and selectively solely. Unbiased of the precise device used, testers ought to endeavor to put in writing XPath expressions which can be quick, unambiguous and sturdy in opposition to adjustments to the DOM. It is because methods like path relativity, giving precedence to attributes which can be distinctive, and incorporation of wildcard characters can improve the era of sturdy XPath expressions for choosing focused internet components throughout completely different internet pages and situations. Methods for coping with dynamic internet components Dynamic internet components are extensively recognized to be a preferred problem within the automated testing course of since all of the XPath expressions the testers work with must be dynamic and versatile, able to be modified, relying on the variations within the doc construction or the properties of the weather themselves. Some strategies like use of incorporates(), starts-with(), and ends-with() situations in targeted checks are good methods to establish components based mostly on partial indicators since dynamic consideration is famous. Talking of the extra axes, the preceding-sibling and following-sibling axes enable navigating via the weather making up the identical node group, which is helpful for dynamic component concentrating on in complicated internet layouts.

REST API

REST API is a software architectural style for Backend.

REST = “REpresentational State Transfer”. API = Application Programming Interface

Its purpose is to induce performance, scalability, simplicity, modifiability, visibility, portability, and reliability.

REST API is Resource-based, a resource is an object and can be access by a URI. An object is “displayed”/transferred via a representation (typically JSON). HTTP methods will be actions on a resource.

Example:

Resource: Person (John)

Service: contact information (GET)

Representation:

first_name, last_name, date_of_birth

JSON format

There are 6 constraints:

1. Uniform Interface

Define the interface between client-server

Simple and can be split in small parts

HTTP verbs

GET:

Read representation of a resource or a list of resources

POST:

Create a new resource

PUT:

Update an existing resource

DELETE:

Remove an existing resource

URIs - resource name

A resource representation is accessible by a URI:

GET /users: path for listing all user resources

GET /users/12: path for the user id = 12

GET /users/12/addresses: path for listing all addresses of the user id = 12

POST /users: path for creating a user resource

PUT /users/12: path for updating the user id = 12

DELETE /users/12/addresses/2: path for deleting the address id = 2 of the user id = 12

HTTP Response

In the HTTP Response, the client should verify the information of two things:

status code: result of the action

body: JSON or XML representation of resources

Some important status code:

200: OK

201: created => after a POST request

204: no content => can be return after a DELETE request

400: bad request => the server doesn’t understand the request

401: unauthorized => client user can’t be identified

403: forbidden => client user is identified but not allowed to access a resource

404: not found => resource doesn’t exist

500: internal server error

2. Stateless

The server is independent of the client. The server doesn’t store user client information/state. Each request contains enough context to process it (HTTP Headers, etc.)

Some authentication systems like OAuth have to store information on the server side but they do it with REST API design.

3. Cacheable

All server responses (resource representation) are cacheable:

Explicit

Implicit

Negotiated

Caches are here to improve performances. In a REST API, clients don’t care about the caching strategy, if the resource representation comes from a cache or from a database…

4. Client-Server

REST API is designed to separate Client from the Server. The server doesn’t know who is talking to it. Clients are not concerned with data storage => the portability of client code is improved. Servers are not concerned with the user interface or user state so that servers can be simpler and more scalable

5. Layered System

Client can’t assume direct connection to server. Intermediary servers may improve system scalability by enabling load-balancing and by providing shared caches. Layers may also enforce security policies.

6. Code on Demand (optional)

Server can temporarily:

Transfer logic to client

Allow client to execute logic

Example: JavaScript

Project Tapestry

Craig Hockenberry • Iconfactory

This post will explain the technology behind Project Tapestry and how we tested it as a prototype. We’ll keep this discussion at a fairly basic level: if you’re a web or app developer, you’ll have no problems following along.

And if you think I’m going to describe RSS feeds now, think again! We’ve come up with something completely new.

I’m excitedly looking forward to seeing the final product and I hope they make their stretch goal of bringing it to the Mac. 🤞🏼 Please, go read about Project Tapestry, and if you’re so inclined please support their effort. I backed them early, it was a no brainer for me.

I really wanted to talk about the choice the Iconfactory made to create a highly extensible platform for plugins. It’s a darned great idea! And I love their choice of pushing network requests through Project Tapestry itself as a way to guarantee plugins can’t phish out user data or credentials to exploit later. 👍🏼

As I was reading the post I came across Craig’s mention of the app having a sendRequest method used by the JavaScript code to make network requests. This grabbed my attention and made me realize this is a way better version of a React Native application.

What I mean by that is, React Native is hosted inside a native iOS application framework and uses native iOS controls on its view controllers or its version of a view controller. The JavaScript code drives everything from networking to user interface (it uses UIKit internally) to render content for the user to interact with. This allows developers to write their app using straight web technologies and run it on iOS and Android.

The project I’m currently involved in is an existing eight year old iOS application built with a mix of UIKit and SwiftUI. On the flip side the Android app of the same age is built using Java and Kotlin with a mix of the original XML based UI and modern Jetpack Compose. They’ve both taken very similar and not unexpected paths.

Enter React Native

Something our client wanted to do is integrate React Native into the existing applications. This has been done before by Airbnb and more recently by Shopify. Each with very different outcomes.

So all of that to say, ours has been successful, in my opinion. We’ve been able to fully integrate React Native and carve out a little set of API’s in the native application we expose to the React Native developers to do work the native application is already doing for them for free. Part of which is all the networking calls.

In the Tapestry blog post Craig points out sendRequest. It’s the call they use to handle requests to the internet for the JavaScript plugin. In our application we’ve exposed a makeRequest call that handles doing any type of network request; GET, POST, PUT, PATCH, or DELETE, and returns a Promise to the caller. Hey, sounds like the Tapestry code! 😄

I have it on my todo list to learn JavaScript. It’s been there for years and years because I knew I’d need it at some point. I really need it now. I can’t see React Native projects going away for the WillowTree team. They’re a very popular way for our clients to get cross platform code and get an iOS and Android app out the door simultaneously without having to spend time, money, and effort on two completely separate code bases.

Over the course of our integration work I’ve done a smidge of TypeScript code to allow other TypeScript devs on the team to make calls into the APIs we’ve exposed in the native application.

It’s been fun and I see a place for JavaScript/TypeScript in my native development world.

As for what Iconfactory is doing, I think it’s a much better version of what React Native does. It gives them the best of both worlds. A beautiful, hand crafted, fully native UI, that gives JavaScript developers the ability to extend the app. That’s a lovely thing. ❤️
