Hiring managers skim in six seconds, then reread

Why the first glance matters Hiring managers spend only a handful of seconds on any new application. In that fleeting moment they are looking for a signal that the candidate aligns with the role. If the signal is missing, the document is set aside without a second look. The decision at this stage is pure triage: does the resume earn the right to be examined more closely, or does it join the pile of forgotten submissions? Because the initial pass is so brief, the layout and phrasing of the opening lines become the most important piece of the communication puzzle.

Google Unveils Gemini 4 Argon With 1 Million Token Context and Cybersecurity Focus

Google has officially introduced Gemini 4 Argon, the next frontier model in its Gemini lineup. The model is positioned for high-value work in software engineering, knowledge-intensive business tasks, defensive cybersecurity, and multimodal analysis and creation. Its most consequential technical specification is support for up to 1 million tokens of context, alongside introductory token-based pricing and a phased rollout that begins with trusted cyber defenders. In Google's official Gemini 4 Argon announcement, the company describes Argon as a model intended to handle longer-running, more compl

Stops Along the Path of Totality

皆既日食2026までに立体視を鍛える——Unity/XR開発者視点で見るAmblyoPunchの分離視VRアプローチ NASAが2026年8月12日の皆既日食パス(西アイスランド・スペイン北部)を公開しました。天体観測において「立体視(stereopsis)」がどれほど体験を豊かにするか——コロナの3次元構造、ダイヤモンドリングの奥行き——は、両眼視機能が正常な開発者なら直感的に理解できるはず。一方で、弱視(amblyopia)や両眼視機能障害(binocular vision dysfunction)を持つユーザーにとって、こうした立体現象は平面的にしか知覚できません。 AmblyoPunchは、Meta Quest(Meta XR SDK / Unity)で構築されたVRビジョントレーニングタイトルです。Seven Sportzによって開発され、弱視のための視覚スキル練習をインタラクティブなゲームプレイと構造化された分離視(dichoptic)トレーニングで提供します。タグラインは「Train Your Brain. Strengthen Your Vision. Beyond the Patch.」(脳を鍛え、視力を強化。アイパッチを超えて)。 ガボールパターン刺激をゲームオブジェクト(コイン)として実装 コインにはガボールパッチ刺激——視覚野でコントラスト、配向、微細ディテ

oss buddy: a local gemma that picks weekend-sized issues so my cousin can finally land his first PR

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend I have a cousin. He has been telling me he wants to contribute to open source for about a year. Every month or two he sends me a screenshot of a repo and asks "is this a good one to start with?" I say yes. He opens it, scrolls for twenty minutes, closes the tab. The screenshot never turns into a PR.

How to create an XML sitemap from a URL list

An XML sitemap is a list of public URLs that you want search engines to discover. It can help with discovery, but it does not guarantee crawling, indexing or rankings. If your site uses a CMS, check whether it already generates a sitemap. WordPress, Wix and other platforms can maintain one as pages are added or removed. Use that sitemap rather than creating a second file that will go stale.

Prop Drilling in React

In React, props are used to pass data from a parent component to a child component. Props are an important part of React because they allow components to share information. However, when data needs to travel through many levels of components, it can lead to a situation called Prop Drilling. Prop drilling means passing data from a parent component to a deeply nested child component through intermediate components, even when those intermediate components do not need the data. For example, imagine the component structure: App ↓ Parent ↓ Child ↓ GrandChild Suppose the App component has a username

Git 3.0's SHA-256 default is a costly mistake, says Chacon

Scott Chacon says Git's plan to make SHA-256 the default hash for new repositories in version 3.0 will be a costly mistake. His argument, published on the GitButler blog on September 30, 2026, lands as the Git project itself says the switch will wait until the wider ecosystem is ready. The dispute matters because every tool that stores or parses a Git commit ID is affected by the answer. Tech AI Wire covered the Git 3.0 plan in September. New repositories get SHA-256 object names, the reftable format and a main branch, and building Git will require Rust.

Bitbucket app passwords removal: what breaks

Key takeaways In the final brownout week app passwords worked for only four one-hour gaps a day — 05:00, 11:00, 17:00 and 23:00 UTC. Anyone reporting that theirs still works was living in those gaps. The REST API returns 401 and git-over-HTTPS returns 410. Two different codes for the same dead credential, which is why the two halves of an integration fail differently. There are three usernames, not one: your account email for REST, x-bitbucket-api-token-auth for git with an API token, and x-token-auth for git with an access token.

Building a Zero-Lag Swiss Tax & Salary Calculator in Next.js (Why We Kept Everything in Browser Memory)

If you’ve ever looked at how taxes and social contributions work in Switzerland, you know it’s notoriously decentralized. There are 26 cantons, each with its own municipal tax multipliers (Steuerfuss), varying church taxes, multiple withholding tax tariffs (Quellensteuer), and statutory pension rules that change based on your exact age bracket. When building LivingSwiss, an expat analytics and financial tool suite, our initial instinct was to treat this like a standard backend system: send the user's salary, canton, and civil status to an API route, calculate the numbers on a server, and retur

The Circuit Breaker Pattern: Stopping Cascading Failures in Microservices

If you run more than a handful of services that call each other over the network, you have probably seen this failure mode: one service gets slow or starts timing out, and instead of staying contained, the problem spreads. Threads pile up waiting on responses that never come, queues back up, and eventually services that had nothing wrong with them start failing too, because they were busy waiting on the one that did. This is a cascading failure, and the circuit breaker pattern is the standard tool for stopping it. The problem: slow failures are worse than fast ones A service that returns an er

Budget Buddy — the money app that talks like a friend, not a spreadsheet

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend My friend Vini travels constantly — a work trip one week, a long weekend somewhere the next, flights and hotels and eating-out-while-away stacked back to back. Her words: "I never know if I'm actually overspending or if it just looks scary because it's all bunched up." She's not bad with money. Travel spending is just impossible to feel in control of — it comes in spikes, and every budgeting app she's tried flashes those spikes red like an alarm, which is exactly the opposite of what she needs when she gets home t

Walkabout Dungeon Golfer Officially in Production After Fake April Fools Reveal

VRで「エイプリルフールの嘘が本物に」――Walkabout Dungeon Golferから見るVRエコシステムの面白さ そして、同じQuestで弱視トレーニングゲームを作った話 UploadVR reported that Walkabout Dungeon Golfer began as an April Fool joke and grew into a fully released hybrid VR and flat‑screen title after the community demanded it. That story illustrates a powerful feedback loop: players voice interest, developers prototype, the community tests, and the product evolves. The same loop drove the creation of AmblyoPunch, a vision‑training game for Meta Quest that my team at Seven Sportz built and shipped. AmblyoPunch targets amblyopia and binocular‑vision dysfunctio
