As a software engineering apprentice at Zone01 Kisumu, I'm constantly looking for opportunities to learn beyond the projects and challenges I work on every day. Recently, I attended the Backend Frameworks Mini-Conference , an event focused on backend development, modern frameworks, APIs, databases, deployment, and career opportunities in backend engineering. The experience reinforced several lessons that every aspiring backend developer should understand. Backend Development I...

Cutting Vercel Fluid CPU with Next.js Server-Side Caching Got an email from Vercel about reaching limits and checked to see Fluid Active CPU spiking for worldcuppicks.co . Obviously I don't want to go to premium, so I implemented certain measures to bring it down. We are in the knockout rounds now, so I wanted to get it sorted before things got worse. First identification Going to the Vercel Observability tab, I was able to see which page was causing the heavy load. The home...

The problem My Mac hard-crashed with seven Claude Code CLI sessions open, across five repos. All gone. The built-in recovery is claude --resume , and it doesn't scale to seven: It only lists sessions for the directory you run it from — you have to remember which repos you were even in, then cd into each one. It takes over the shell you run it from — so you're spawning windows and retyping paths anyway. The solution Claude Code already stores everythi...

The morning I announced what I'd been building, a comment showed up on the post. It was friendly. It opened with a compliment, agreed with me, and then walked through a few of the risk signals worth thinking about...who owns the code, what a change actually touches when it runs, whether it goes anywhere near auth or payments. Solid stuff. It was also every point I'd made in the post it was commenting on. Then it suggested I go build a tool that scores that risk automatically and flags it befo...

Tailwind's class names are readable. items-center tells you what it does. But it's not CSS. It's Tailwind's own name for align-items: center , & that name doesn't always trace back cleanly. gap-x-4 reads fine, but gap-x isn't a CSS property. column-gap is. Same with shrink-0 for flex-shrink: 0 , or flex-col for flex-direction: column . Every one of these is something you learn on top of CSS, not something CSS already taught you. I didn't want a second vocabulary. I wanted t...

Rattribute.js allows you to define different HTML attributes for different viewport widths using simple data-* attributes. Whether you need to change classes, targets, ARIA attributes, or any other HTML attribute, Rattribute.js updates your elements automatically as the browser size changes — without writing responsive JavaScript. This is a brand new project that I started a few days ago! williamtroup / Rattribute.js ...

Single sign-on has a quiet premise: when a user arrives from an identity provider, that provider has already vouched for them, so you can skip the password and just let them in. The whole point is to trust the IdP. The bug we're about to describe lived in the gap between "trust the IdP to authenticate its own users" and "trust whatever the IdP tells you about who its users are." Those are not the same sentence, and the difference was an account takeover. Here's the setup. A tenant on our plat...

Escrevemos uma vez sobre o imposto de funcionalidade : o truque de cobrar de você para acionar um booleano que já está escrito, sobre uma infraestrutura que já está rodando. Aquele texto era o argumento. Este é o recibo. Porque "SSO custa a mais" é fácil de concordar com um aceno de cabeça e fácil de esquecer. Um número numa fatura é mais difícil de esquecer. Então vamos colocar a fatura inteira sobre a mesa, para três momentos pelos quais todo produto B2B passa: a base da plataforma (cobr...

AI assistance disclosure: This article was drafted with the help of Claude. All technical content, design decisions, code references, and screenshots reflect production systems I designed and operate at airCloset; the prose was revised by me prior to publication. Hi, I'm Ryan , CTO at airCloset. In the previous series, code-graph deep dive (Part 2) , I wrote about making a 46-repo codebase semantically searchable for AI. The final issue I left open in that piece was the absence of dy...

The Wallet-as-a-Service provider will demonstrate its deposit, withdrawal, and KYC infrastructure at WebX in Tokyo on 13-14 July

GLM-4.7-Flash should fly on a small box: 30B total, ~3B active. On a Radeon 780M mini PC it crawled and fell apart past short context. The cause was not the weights or the quant. It was Multi-head Latent Attention with no runtime that implemented it, so the model fell back to plain attention and the KV cache ballooned ~17x. Swapping to ik_llama.cpp with a real MLA path fixed it.

This first installment introduces a spatial analytics framework for precision agriculture that replaces arbitrary rectangular grids with Uber's H3 hexagonal indexing system. Using a simulated Iowa corn field, it demonstrates how to aggregate GPS-tagged agronomic data, validate spatial structure with Moran's I, and generate management zones using K-Means and SKATER, laying the foundation for more accurate variable-rate fertilizer prescriptions.

Customer-facing AI has three layers: doing (automating tasks), knowing (turning customer signal into insight), and anticipating (predicting the next need). Most companies pour effort into the bottom layer because it is easiest to measure, and leave the valuable upper layers untouched. The advantage goes to teams that climb.

OLTP databases like PostgreSQL are optimized for fast reads and writes on specific records - orders, users, payments. OLAP databases like ClickHouse are built for a different job: aggregating and analyzing millions of rows at once. The same SQL query that takes minutes in PostgreSQL runs in seconds in ClickHouse, thanks to columnar storage. The two systems complement each other - PostgreSQL stores your application data, ClickHouse handles analytics on top of it.

The thesis: AEREDIUM founder Albert Dadon argues the 2022 SWIFT disconnection was misread as a political story when it was an engineering one — credible neutrality can't be voted into existence, it has to be constructed. The mechanism: AEREDIUM is a privacy-preserving Layer 1 ("the Trust Layer") that pushes rule-enforcement into attested hardware and threshold cryptography, so no single party — including the company — can override it unilaterally. "A key nobody holds": its signing system (AERK...

Compare five ways to convert DOCX to PDF in C#, from Office Interop to LibreOffice, cloud APIs, and native .NET libraries.

Dmytro Rukin is the CEO of LaFinteca, a payment infrastructure company operating across Latin America (Brazil, Mexico, Chile, Peru, Colombia) and Europe. He has spent close to a decade in payments, starting in Eastern Europe, before turning his attention to the region he now considers the most interesting payments market on the planet. We sat down with him to understand how he reads Latin America, why Brazil sits at the center of his thinking, and where he believes the money is moving next.

There is a well-known trick for climbing ASR leaderboards: fine-tune on data that closely resembles a testset, submit, watch your rank improve. We did exactly that with AMI, the one testset that consistently separates serious models from optimised ones. We went from rank 26 to rank 16. Here is what actually happened, what broke along the way, and what it means for how you read anyone's leaderboard score.

Otomato is a portfolio-aware DeFi assistant that helps crypto users monitor positions across DeFi, perps, prediction markets, tokens, and NFTs. Instead of forcing users to refresh dashboards manually, it sends low-noise alerts when something important changes.

Drawing on experience in both banking and children's mobile apps, the article explores which product management skills transfer across industries. It argues that fintech builds rigor around trust, metrics, and stakeholder management, while consumer products sharpen experimentation, emotional design, and observational research, making the combination particularly valuable for modern product leaders.

The article argues that AI is changing the role of software engineers rather than replacing them. As code generation becomes increasingly automated, developers who excel at system design, verification, architecture, communication, and mentorship will remain in demand, while companies must rethink how they train the next generation of engineers.

Rather than competing to issue stablecoins, major asset managers are positioning themselves to manage the reserves backing them. The article argues that the GENIUS Act created an entirely new asset management category, prompting firms like BlackRock, Fidelity, State Street, Goldman Sachs, BNY, and Invesco to launch or file stablecoin reserve funds that could become foundational infrastructure for a multi-trillion-dollar digital dollar ecosystem

AI can make communication faster, cleaner, and more reliable. But when too much of it is delegated, something harder to measure can disappear: the feeling that a real person is present. This piece explores the hidden cost of automating communication too far.
