This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built The average student opens their notes 3 days before the exam. The above average student opens them the night before. Either way, they both end up on YouTube at 3am watching a guy explain thermodynamics with a whiteboard and too much energy. I built something better. I built Forge AI — a collaborative AI study platform that turns your lecture notes, PDFs, and YouTube links into a full study session with an AI tutor that actually talks back. Here is what it does: 📄 Upload your notes or paste a YouTube link — Forge AI reads everything and builds you a prioritised study plan in seconds. 🧠 Deep Dive into any topic — get full AI generated study notes, a mnemonic memory trick, and a built-in quiz. 🎙️ Talk to your AI tutor live — it listens, speaks back, and you can see the transcript building in real time as it talks. 👥 Create a Forge Room — invite your study group, ask the AI questions together, battle each other in a live quiz, and everyone sees everything at the same time. It started as CrammAI . A solo study tool I built under exam pressure. Well, it could generate a study plan from your uploaded files and quiz you on topics. That was it. No voice. No collaboration. No rooms. No Finesse. Just you, alone, cramming at 2am. Five months later I came back to finish it. The result is Forge AI. Demo Live app GitHub Here is what Forge AI can do: 1. Upload your materials and pick your mode Three modes based on how much time you have: 🧘 Cruise Control — 1+ week until exam 🚀 Turbo Mode — 2 days left ⚡ Zoom Mode — due tonight 2. Paste a YouTube link — it transcribes automatically ts export const apiFetchYoutubeTranscript = async ( url : string ): Promise < string > => { const videoId = extractYoutubeId ( url ); const response = await fetch ( `/api/transcript?videoId= ${ videoId } ` ); const data = await response . json (); return data . transcript ; }; No manual transcription. Paste the link, Forge AI pull

I'm starting a new project. It's the most ambitious thing I've attempted from a phone. The goal: an AI agent that controls a smartphone. It opens apps, navigates screens, taps buttons, types text, and completes multi-step tasks. All offline. All local. No cloud. This is Day 1 of a public build log. No fluff. Just what I'm building, how it works, and what breaks along the way. What I'm Building An autonomous AI agent that runs entirely on an Android phone. You give it a command in plain English: · "Open WhatsApp and message Mom I'll call later." · "Search for Kotlin jobs on Wellfound." · "Open my notes and summarize what I wrote yesterday." The agent parses the command, plans the steps, and executes them—opening apps, finding the right buttons, typing text, hitting send. No cloud. No API keys. Just a phone that acts on your behalf. The Stack Component Tool AI Brain Gemma 4 E4B (local, via Ollama) Runtime Termux (Linux on Android) Phone Control ADB + UI Automator Orchestration Python Why This Matters Most AI agents live in the cloud. They need internet, APIs, and someone else's server. A local agent that runs on a phone means: · Privacy: your data never leaves your device. · Offline: works even without internet. · Accessible: built for the device billions of people already own. The Hard Parts I Already See · The agent needs to "see" the screen to know where to tap. Text detection is doable. Image-based buttons are harder. · Multi-step tasks need verification. If one tap misses, the whole chain fails. · Android permissions. ADB requires developer mode. A user-facing version would need a workaround. What's Next · Day 2: Create the repo. Set up the project structure. Push the first working script. · Day 3: Get screen text detection working with OCR. · Day 4: Test a full 3-step task. This is Day 1. The repo goes live tomorrow. Follow along if you want to see something rare get built from scratch.

A few months back I got frustrated. I needed to calculate something — nothing crazy, just a loan payment — and every site I landed on either wanted me to sign up, showed ads on every input, or was in English only (not helpful when sharing with family abroad). So I built Calculora . It's a free calculator site. 150+ tools, 13 languages, zero data collection. Everything runs in your browser — nothing gets sent anywhere. Why 13 languages? Because most people on the internet don't speak English as a first language. I wanted it to actually work for them — not just have a translated homepage, but real localized URLs, right-to-left layout for Arabic, the whole thing. Getting that right in Next.js took more time than I expected. Each tool has a different slug per language, so the routing has to map hundreds of combinations correctly. Totally worth it though. The math rendering For tools like the equation solver and statistics calculator, I wanted the formulas to look like real math — not just text. I used KaTeX for this. It's fast, lightweight, and renders LaTeX properly in the browser. The step-by-step solutions actually show the working — discriminant, roots, the full process — rendered cleanly. Some tools I'm proud of Equation Solver — linear and quadratic, with full steps shown Statistics Calculator — mean, median, mode, IQR, std dev, exportable FIRE Calculator — retirement planning done simply Debt Snowball/Avalanche — side-by-side payoff comparison What's next More tools, better mobile experience, and filling in gaps across the language versions. If you try it, I'd genuinely love feedback — especially on anything that feels off or missing. calculora.net

Launch week for a side project means the same chore every time: export the logo, open Figma, create artboards for LinkedIn (400×400 and 4200×700 cover), Google Business Profile (1200×1200 JPEG with a minimum file size or Google rejects it), YouTube (2560×1440 with a safe zone nobody remembers), Open Graph (1200×630), Instagram (circle crop), Discord, TikTok… Design tools are great at making brand assets. They are slow at batch-exporting exact platform specs — especially when encoding rules differ (PNG vs JPEG, max KB, min KB for GBP, center-right vs YouTube-safe positioning). So we built a small free tool: one SVG or PNG in → 21 platform files out. What it actually does Upload a logo. Pick categories (or take everything): 8 profile icons — mark-only, padded for circular crops (LinkedIn, X, GBP, Facebook, Instagram, YouTube, TikTok, Discord) 2 profile lockups — logo + wordmark for LinkedIn company and GBP 7 banners/covers — including LinkedIn 4200×700, YouTube safe-area channel art, Facebook cover under 100 KB target, Open Graph 1200×630 4 post sizes — Instagram square/portrait/story, Pinterest pin Outputs are PNG or JPEG per platform rules. White background. ZIP download. Why not Canva? Canva is excellent for templates and marketing creatives. For “I already have a logo, give me every official size,” you duplicate frames and export manually — often behind a paid tier for brand kits and bulk workflows. This tool does one job, free, no account: 👉 https://varnox.io/tools Longer write-up with platform gotchas (GBP min JPEG size, YouTube safe area, etc.): 👉 https://varnox.io/blog/free-social-media-logo-size-generator Privacy (because it’s your logo) SVG uploads sanitized before render Generated files expire after 30 minutes — nothing permanent stored No signup We use the same catalog internally when onboarding clients onto GBP + LinkedIn + OG tags. Shipping it publicly was easier than answering “what size is our Facebook cover again?” for the fifth time. Stack note (for

Three years ago we had our first real outage. Six hours of downtime. Thousands of angry users. Multiple executives on the call. Here's what we did right, what we did wrong, and what we'd do differently. What we did right 1. Communicated immediately. The moment we knew we had a problem, we updated the status page and emailed our biggest customers personally. Not when we had answers. When we had a question. 2. Had a single incident commander. One person making calls. Not a committee. When the CEO tried to direct technical work, the IC politely rerouted and told her where her help was actually needed (talking to customers). 3. Took care of our people. During hour 4, I ordered food. During hour 5, I forced the primary engineer off the call for 20 minutes to walk outside. Long incidents destroy people. You have to feed them and force them to rest. 4. Wrote it down as we went. We had a shared doc with a live timeline. When the post-mortem came, we had every decision captured. What we did wrong 1. Tried to fix the root cause during the incident. For the first 2 hours, we were digging into why the database was struggling. We should have been mitigating (rolling back) first. 2. Let too many people 'help.' By hour 3, we had 12 engineers in the call. Half of them were useless. The IC should have kicked people out sooner. 3. Gave optimistic estimates. 'We'll be back in 30 minutes.' We were not back in 30 minutes. That miscommunication was worse than saying 'unknown.' 4. Didn't prepare the executive communication. The CEO had to answer customer questions in real time with no script. We should have drafted talking points for her after hour 1. What we'd do differently Mitigate first, investigate second. Always. Cap the number of active engineers at 4 during an incident. Others go on standby. Default to 'unknown' for estimates. Only give a number when we're sure. Assign someone explicitly to 'executive liaison.' Their job is to keep the C-suite informed without interrupting the tec

We run 10+ web products. For years our SEO tooling was a $100+/month subscription we mostly used for one job: technical audits. The keyword and backlink dashboards sat untouched while the bill renewed every month. At some point the math stopped making sense, so we rebuilt our stack around what we actually use. Here's the honest breakdown — what we kept free, what we replaced, and why. What a technical audit actually needs to check Before picking tools, it helps to know what you're auditing. The technical layer is finite and well-defined: Crawlability — robots.txt, broken internal links, redirect chains Indexability — noindex tags, canonical correctness, soft 404s, orphan pages Sitemaps — only canonical, indexable, 200-status URLs On-page — titles, meta descriptions, one H1, valid structured data International — hreflang reciprocity (if you're multilingual) Performance — Core Web Vitals (LCP, CLS, INP) That's it. None of it requires a keyword database or a backlink index — the two things you're really paying $100+/mo for in the big suites. The free tools that cover most of it Google Search Console is non-negotiable and free. The Pages report is the source of truth for what's indexed and why the rest isn't. PageSpeed Insights (free) gives you real Core Web Vitals. Screaming Frog's free tier crawls up to 500 URLs, which is plenty for small sites. For a long time that was our whole stack: GSC + PageSpeed + free Screaming Frog. If your site is under 500 pages, you may not need anything else. Where it broke down for us The free Screaming Frog cap (500 URLs) is the wall. Several of our sites are bigger, and re-auditing them meant either the paid Screaming Frog licence (annual) or going back to a monthly suite. Both felt wrong for something we run after every deploy. So we built our own crawler for the technical layer — and then, honestly, turned it into a product because other people we talked to had the same problem. It does the whole checklist above across the entire sit

If you run Aviatrix on Azure, there is a slow-moving infrastructure change happening underneath your gateways right now that is worth paying attention to. Microsoft started rolling out a new generation of network hardware on May 26, 2026, called MANA (Microsoft Azure Network Adapter). For most Azure workloads, the change is invisible. For network virtual appliances (NVAs) like Aviatrix gateways, it is not, and Aviatrix has issued a field notice ( FN-2026-AZ-001 ) telling customers to take action. What is MANA and Why is Microsoft Rolling it Out? For roughly a decade, Azure VMs with Accelerated Networking enabled have used Mellanox-based NICs exposed to the guest as mlx4/5 SR-IOV adapters . SR-IOV (Single Root I/O Virtualization) lets the VM talk to the network card hardware directly, bypassing the hypervisor's virtual switch. This is what gives Accelerated Networking its low-latency, high-throughput characteristics. Microsoft has been quietly building its own in-house networking silicon. MANA is the result: a Microsoft-designed network adapter that replaces the Mellanox hardware Azure has been using on the host side. From an Azure customer's perspective, MANA preserves Accelerated Networking semantics, but the device the guest OS sees is different. The driver is different. The interface name is different. And that is where Aviatrix gateways run into trouble. Why Aviatrix Gateways Are Affected Aviatrix gateways are not generic VMs. They run a custom data plane that binds tightly to the underlying NIC for performance reasons. Specifically, the gateway image expects the Mellanox driver to be present and operational. On MANA hardware, that driver is no longer in play, and the gateway image does not yet include a MANA-aware driver. Per the field notice, the symptom is intermittent performance degradation rather than an outright outage. That makes it harder to detect: throughput drops, latency spikes, or session resets that look like noise can be the early signs of a gate

It'll come as a free update for players who own the game already.

Citizen Sleeper creator Gareth Damian Martin has revealed their latest game, Signet City. The new RPG casts players as a fungal parasite in a dying city.

We're likely to see more price increases as the big AI companies plan to go public.
