Introduction In this project, I set out to analyze a dataset of products listed on Jumia, one of Africa's leading e-commerce platforms, with the goal of understanding how pricing strategies, discounts, and customer reviews influence overall product performance. Using Microsoft Excel, I cleaned and prepared the raw dataset, engineered new features to categorize products, ran correlation and trend analyses to uncover relationships in the data, and ultimately built an interactive dashboard to present the findings in a clear, business friendly format. The objective was not just to explore the numbers, but to answer practical business questions: Do bigger discounts actually drive more customer engagement? Does price influence how a product is rated? Which products are genuinely performing well, and which ones might need a different pricing or marketing approach? This article breaks down the full process behind how I turned raw data into a finished report from initial data cleaning to the creation of an interactive dashboard. The following is the uncleaned data(original dataset) Data Set Overview. The dataset contains information about products listed on Jumia with the following columns: • Product: Name of the product. • Current Price: The current selling price of the product (in KSh). • Old Price: The original price before discount (in KSh). • Discount: The percentage discount offered on the product. • Review: The number of customer reviews received by the product. • Rating: The average customer rating of the product (out of 5). Data Cleaning and Preparation On a separate sheet after copy pasting the original data set I had to ensure there was no any present duplicate in the dataset. Now that I had removed any duplicates that was present, next process was changing the cell format for each column from General to the appropriate data type i.e. Text for product names, Currency for prices, Percentage for Discount and Number for ratings and reviews. Next, I used Find and Repl

Introduction Why am I writing this article? The reason is simple: a while ago, a new project at my company required us to integrate Google Pay and Apple Pay. The service had already completed its credit card payment flow. However, management later requested support for Google Pay and Apple Pay as well. Since none of our previous company projects had integrated Apple Pay, I became the first person in the company to take on this task. With the help of AI, the payment integration itself was completed in about one day. However, a new problem came up: The code was finished, but how were we supposed to test it in the UAT environment? This is basically a record of my experience and the problems I encountered while testing Apple Pay in the Sandbox environment. I hope it helps other engineers who are stuck in a similar testing environment. Problem 1: How to Configure the CER and Private Key At the moment, I only have a .p12 file. The payment integration side has already configured the Apple Pay certificate and generated the corresponding CSR. The only remaining step is to configure the environment variables on the application side. The contents of a .p12 file are generally as follows: .p12 ├── Certificate ├── Private Key └── Certificate Chain (may be included) The overall process is: .p12 ├── Extract the Certificate / PEM ├── Extract the Private Key └── Verify that the CSR, Certificate, and Private Key belong to the same key pair The following process uses OpenSSL: # Inspect the p12 contents without outputting the private key openssl pkcs12 -info -in apple-pay.p12 -noout # Extract the certificate openssl pkcs12 \ -in apple-pay.p12 \ -clcerts \ -nokeys \ | openssl x509 -out cert.pem # Extract the private key openssl pkcs12 \ -in apple-pay.p12 \ -nocerts \ -nodes \ | openssl pkey -out private-key.pem -nodes means that the exported private key will not be encrypted again. Therefore, the generated private-key.pem must be stored securely. It should never be committed to Git or pr

The steel industry isn’t exactly known for innovation. Very little has changed about purifying iron ore since the process was invented and commercialized in the 1850s. The majority of steelmakers melt solid iron ore at dizzyingly high temperatures inside blast furnaces, where the material reacts with gases to trigger chemical reactions that remove oxygen. It…

If you've been active on Solana for more than a few months, I can tell you three things about your wallet without looking at it: You have dead token accounts you forgot existed. If you've ever traded on pump.fun, there's probably an unclaimed reward sitting in a program you never interacted with. Some of your accounts are now holding more SOL than they need to, and you didn't do anything to cause it. None of this is a bug. It's a side effect of how Solana's storage model works — and once you understand the mechanism, it's actually a pretty elegant piece of design that most people just never get exposed to. Let's go through it. 1. Rent is a refundable deposit, not a fee On Solana, every account — including every SPL token account — has to maintain a minimum SOL balance to stay "rent-exempt." This isn't a subscription. It's a bond: SOL locked against the account's existence, refunded in full the moment you close it. const rentExemptReserve = await connection . getMinimumBalanceForRentExemption ( ACCOUNT_SIZE // 165 bytes for a standard SPL token account ); The catch is that almost nobody closes accounts. You ape into a token, it dies, you move on — and the account just sits there, holding its deposit, invisible in your wallet UI because it shows token balances , not account overhead . Multiply that by every token you've ever touched, every NFT mint you tested, every airdrop you claimed once and ignored, and you're looking at real, non-trivial SOL parked across dozens of accounts doing nothing. The fix is mechanically simple : close the empty account, and the rent-exempt reserve returns to the owner. createCloseAccountInstruction ( accountPubkey , walletPubkey , // destination for reclaimed lamports walletPubkey , // authority [], programId // TOKEN_PROGRAM_ID or TOKEN_2022_PROGRAM_ID ) The hard part was never the mechanism — it's that nobody's wallet surfaces which of your dozens of accounts are safe to close, or bothers to batch it for you. 2. Rent reduction created

Creating a website is more than just writing code. After building a project with HTML, CSS, or JavaScript, developers also need to consider how the website performs, how secure it is, and how easily users can access it. As a young developer, I think these aspects are important to learn through practice. In this article, I want to share my experience exploring Tencent EdgeOne Makers, along with some technical considerations and best practices that I found useful. Getting to Know Tencent EdgeOne Makers Tencent EdgeOne Makers provides an interesting environment for developers to experiment with their projects and explore modern web services. For beginners, one of its advantages is the opportunity to experience the complete journey of a web project. We can start by creating a project locally, testing its features, and then making it accessible online. This process gives developers a better understanding of what happens beyond the coding stage. A website that works on a personal computer still needs to be tested in a real environment before it can provide a good experience for users. My Technical Review Easy Project Experimentation One thing I like about EdgeOne Makers is the opportunity to experiment. Developers can start with a simple project and gradually improve it. This is useful for students and beginner developers because learning does not always have to start with a large or complicated application. A small website can already teach important lessons about structure, configuration, performance, and accessibility. Performance Matters A website should not only work correctly; it should also feel comfortable to use. Large images, unnecessary JavaScript, and unused resources can affect loading times. Because of this, developers should review their project before making it available to users. Some simple practices include compressing large images, removing unnecessary files, and keeping the website structure clean. Performance is especially important because users may
