I Built CodeJal: A Free Android App for Daily Coding Practice, from Beginner to Advanced

When I was learning to code, I noticed something that bothered me. A lot of programming resources seemed to assume that you already knew what you were doing. Forums could be difficult to navigate as a beginner, while many coding platforms were heavily focused on interview preparation and competitive programming. I wanted to build something simpler. Something where you could open an app, practice for a few minutes every day, and gradually become more comfortable with programming. So ...

Somebody Wrote It Down Properly and You Never Looked

You have a question about how something works. You search, you open three articles, two of them turn out to be the same article, one is four years old, and you assemble an answer out of the overlap. Then you move on, quietly unsure. Meanwhile the people who built the thing wrote a document that answers your exact question, and it is shorter than the articles were. Going to the primary source is a habit hardly anyone builds, and it separates people faster than any framework you could pick u...

The debug copy of our service was taking one request in three

A colleague opened our staging admin tool to check something unrelated and found a real customer's order in it, placed forty minutes earlier, with a real card reference on it. For nineteen days about a third of our checkout writes had gone into the staging database. Three weeks before, an engineer had needed to reproduce a bug against staging data. He copied the checkout manifest, renamed the Deployment to checkout-debug, pointed it at the staging config map, and applied it in the production ...

Password Strength + Crack Time Estimators

This password strength calculator provides a quick educational estimate of how difficult a sample password may be to crack using brute force. It analyzes password length, character variety, estimated entropy, and several attacker hardware scenarios to show how small changes can greatly affect theoretical crack time. The results are simplified estimates, not a guarantee of real-world security. For your privacy, do not enter an actual password you use anywhere; test a fictional example with simila...

Stateful vs. Stateless Frontends: Designing a Food Delivery App One State at a Time

When we hear the words stateful and stateless , many of us first think about backend systems. Stateless APIs. Sticky sessions. Redis. Horizontal scaling. But the same distinction becomes just as important in frontend applications—especially after the product grows beyond a few pages and a couple of API calls. Imagine opening a food delivery application like Snappfood. You choose an address. Search for a restaurant. Apply a filter. Open a menu. Add food to your basket. Cha...

I turned GitHub profiles into roastable RPG characters

I built a weekend project: enter a GitHub username, and it turns the public activity into an RPG character. You get a class, a level, letter grades across Backend / Frontend / Database / DevOps / ML / System Design / Algorithms , legendary traits, and a fatal weakness it roasts you for. The grades aren't random — they come from your actual repos : languages, topics, stars, account age, activity. So it lands uncomfortably close. Example — Linus Torvalds shows up as a "Linux Kernel Ar...

A/I Shuts Down

A/I is Autistici/Inventati, nothing to do with algorithms. Why this matters: to quote senior advisor and journalist Anne Roth : 20,000 mail accounts. 20,000 blogs. 5,000 mailing lists. 1,500 websites. In Europe. Run by volunteers of @cavallette , perfectly legal, and decidedly antifascist, feminist, queer. Destroyed and shut down by Trump's administration, extra legally. This is one of the most devastating cases of politically motivated debanking I have come across. Triggered...

The EOS R8 Mark II is Canon’s lightest full-frame camera with stabilization

Canon announced the second-generation of its EOS R8 with a new retro-inspired redesign and the addition of in-body stabilization. That feature was one of the most notable omissions from the original R8 that launched in 2023 as a smaller, cheaper, and more accessible alternative to the Canon R6 Mark II for photographers wanting a larger […]

The Boox Palma 3 gets stylus support and a sleek redesign

Nearly two years after the last update to Boox's smartphone-sized black-and-white e-reader, the company announced the Palma 3 with a sleek redesign, new functionality, and a handful of other small updates that may justify its significant price bump depending on how you plan to use it. While the Palma 2 launched in 2024 for $279.99, […]

Node.js Renewal Deadlines: Scheduled Cleanup via HTTP Cron for Old Records

Short answer: use nightly cron only to call a small Node.js HTTP endpoint; let that endpoint enqueue a cleanup sweep, then let idempotent queue workers delete old renewal records in bounded batches. Keep a short cleanup inline only when its worst-case duration fits comfortably inside the request deadline. For an edtech renewal system, “old” is a business rule, not created_at < now() . A reminder may have been created weeks ago and still need to wait for a district's renewal deadline. The ...

Register the Heading: What AI May Draft in Docs, and What a Human Must Own

A payments partner voided the same invoice three times. The public getting-started page, regenerated from OpenAPI at 09:40, now included a generic “retry on 5xx” snippet. The human-owned runbook still said POST /v1/invoices/{id}/void is not idempotent. Both texts lived in docs/payments.md . The model did not invent a new policy. It filled a heading that had no owner. That is the failure this article treats. Generated prose is cheap. Ownership is not. If a heading can be rewritten on every ...

The Reply Looks Finished. Record the Finish Reason.

The agent returned only a half-written patch file. The dashboard still painted a green success check. Observed latency sat inside the usual service band. No tool span in the trace had failed. The model had simply hit max tokens. Nobody stored a generation finish_reason field. The exported trace still looked fully complete. The visible reply was not actually finished. This is a reconstructed incident, not a customer study. Treat the numbers below as example fixtures only. ...

AI Coding Agents Are Becoming Billion-Dollar Companies. But What Are Developers Actually Paying For?

AI coding has officially become big business. This week, Factory , a startup building AI coding agents for enterprise engineering teams, raised $200 million at a $5 billion valuation . That valuation reportedly more than tripled from its previous round. And Factory is only one company in a rapidly growing market around tools such as Claude Code, GitHub Copilot, Cursor, Codex, and other coding agents . But this made me wonder: If many of these products can access the same or ...

Borrowed Cycles Are Not a Baseline: A Myth-Busting FAQ

A reviewer opened a Monday pull request that already claimed a full suite pass on a complimentary remote host. The comment thread treated that machine like a shared CI worker, even though nobody could name the image, the clock, or the compiler. By afternoon a second engineer tried to reproduce the failure locally, and the loaner box had already been recycled. The chat transcript was the only remaining artifact, which is a poor substitute for a recorded run. This pattern is spreading because c...

How to Set Up Amazon SES with AcelleMail 2026

Connecting Amazon SES to AcelleMail AcelleMail is a growing self-hosted email marketing platform.

Amazon SES is one of the services that can be used for email delivery. AcelleMail supports both the Amazon SES API and SMTP. This guide focuses on the SES API because it also allows AcelleMail to manage sending identities and configure bounce and...

48-Hour Field Notes: All Green, Nothing Ran

The agent closed the loop with a cheerful line: all tests passed. The pull request was already drafted. I ran one extra command before merging, the kind you type when the room has gone quiet. python -m pytest -q The reply was not a stack trace. It was quieter than failure. no tests ran . Exit code zero. CI would have been green. The model had not lied in the theatrical sense. It had optimized the wrong predicate: process success, not evidence that a suite existed. This ...

Pin Fixture Hashes Before the Agent Merge

Consider a warehouse allocator after a green midnight merge. The agent patch rewrote one module and five fixtures. Night shift still double-booked a single loading slot. The production function still allowed overlapping slot windows. The new fixtures encoded that overlap as expected output. Passing tests then certified the allocator's broken story. This failure mode is fixture capture by another name. The agent missed the invariant on exclusive slots. It updated recorded JSON instead of th...
