Ask ChatGPT or Perplexity "what's the best note-taking app" and you get a shortlist of three to five names. Either you're on it or you don't exist in that channel. And buying research keeps moving there. People call measuring this GEO or AEO tracking now. The way most teams do it is pasting questions into chatbots by hand and eyeballing the answers. That stops scaling at about ten questions, and you can't trend it week over week. Doing it programmatically Don't scrape the chat UIs. It's fragile, against ToS, and breaks weekly. The engines all have official APIs with web search: Perplexity's sonar models return answers with citations built in OpenAI has gpt-4o-search-preview for live web search Gemini's gemini-2.5-flash supports Google Search grounding One OpenRouter key covers all three through a single endpoint, which keeps the code boring. For each buyer question you care about, record four things per engine: was the brand mentioned, how early in the answer, was your domain cited as a source, and how often competitors appeared. That last one gives you share of voice. The packaged version I built this as an Apify actor: AI Brand Visibility Tracker . You give it a brand name, domain, competitors, and topics. It generates realistic buyer questions and returns one JSON row per check: brandMentioned , positionScore , brandCited , shareOfVoice , citedDomains , plus a per-engine summary. Schedule it weekly and you have an AI visibility trendline for client reports. $0.05 per check. The field that actually matters citedDomains is the actionable one. It tells you which sites the AI engines treat as sources for your category. Getting mentioned on those specific domains is how you move your visibility. It's link building, except the target list comes from the AI's own citations instead of a guess.

I wanted to know when people mention a brand on Bluesky. Simple ask. Turns out Brandwatch, Mention, Hootsuite, basically every social listening tool, still doesn't cover it. They're all busy with X and Instagram while Bluesky sits at 27M+ monthly users. So I looked at doing it myself and found out something most people miss: you don't need to scrape anything. Bluesky runs on the AT Protocol, which is open by design. Public posts are searchable through a documented endpoint. No login, no API key. GET https://api.bsky.app/xrpc/app.bsky.feed.searchPosts?q=YOUR_BRAND&sort=latest&limit=100 That returns full post objects. Text, author handle, timestamps, like/repost/reply counts, embedded links, hashtags. Everything you need. Two things that broke my first version Worth writing down because most tutorials get this wrong now: The public.api.bsky.app host that older guides point to returns 403 for search. Use api.bsky.app instead. As of July 2026, unauthenticated search rejects cursor pagination. Page one works fine, page two gets you a 403 with "request forbidden by administrative rules". The nasty part is it looks like rate limiting, but it isn't. The workaround: paginate by time. Use sort=latest , then pass until= with the createdAt of the oldest post from the previous page. Dedupe on uri because the boundary post shows up twice. If you don't want to maintain any of that I packaged the whole job as an Apify actor: Bluesky Mentions Scraper . Keywords in, clean JSON out. It handles the pagination and retry stuff above, filters replies if you want, scores basic sentiment, and can pull follower counts for each author so you can sort mentions by reach. Runs on a schedule, exports CSV, plugs into Slack or n8n through Apify's integrations. It also works as an MCP tool inside Claude or Cursor. Pricing is per result, $4 per 1,000 mentions. No subscription. What I actually monitor Brand and product names plus the common misspellings. Competitor names, because share of voice on Blu

TL;DR Two Laravel backends started serving Flutter apps on the same day — an events platform (auth, orders, offline check-in) and a helpdesk product (ops mode for agents). gatherhub-web moved to plans-only pricing with a comparison matrix driven by one data file. A hardening pass: payment-safe queues, gateway reconciliation, one heavyweight dependency dropped. Two mobile APIs in one day Coincidence, but a useful one: two products I'm building both needed their Laravel backends to serve mobile apps this week. The events platform got the full foundation — token auth (login/refresh/logout/me), participant orders, mobile payment with status polling, push-device registration, and an offline-first staff check-in flow. That last one is the interesting bit; I wrote it up as its own post. The helpdesk product went the other way: its API was client-only, and today it became role-aware. The same endpoints now serve ops agents working tickets from their phones, with abilities deciding what each role sees. One API surface, two personas, no duplicated /admin routes. The lesson that repeated in both: API Resources are the contract. The moment a mobile dev consumes your endpoint, every field you accidentally leak becomes a field you can't remove. Plans-only pricing (public) gatherhub-web , the Next.js marketing site, dropped à-la-carte feature pricing for three plans and gained a plan comparison matrix. Everything renders from a single plans.ts — the matrix, the pricing cards, the enterprise page — so the marketing site can't drift from what's actually sold. A pricing page is a contract too; it deserves a single source of truth as much as your API does. Hardening pass Change Why Bulk email blasts isolated to their own queue one big send must never delay a payment webhook Reconciliation command for stuck pending orders webhooks fail silently; polling the gateway is the safety net maatwebsite/excel → spatie/simple-excel for exports streams rows instead of building sheets in memory, s

TL;DR A gate check-in app can't depend on live Wi-Fi: scans must work offline and sync later. Four endpoints do it: manifest download, idempotent batch push, delta pull, online search. Client-generated UUIDs + a unique index make retries safe. Duplicates are a success status, not an error. The problem Physical event, staff scanning tickets at the door, venue Wi-Fi exactly as reliable as you'd expect. If your API sits in the hot path of every scan, the queue at the gate grows at the speed of the worst signal bar in the building. So the design flips the roles: the device owns check-in, the server owns convergence. Like a cashier who keeps a paper ledger when the till goes down — record now, reconcile later. The API surface Endpoint Purpose GET /staff/events/{uuid}/manifest paginated ticket snapshot, downloaded before gates open POST /staff/events/{uuid}/check-ins/batch push queued scans; safe to retry GET /staff/events/{uuid}/check-ins?since=<cursor> pull what other devices did GET /staff/events/{uuid}/participants?q= online fallback search (lost ticket, typo) The sync loop Device Server |--- GET manifest (before event) ------->| | scan offline, queue locally | |--- POST batch [{client_uuid, ts}] ---->| dedupe on client_uuid |<-- 200 {applied | duplicate per item} -| |--- GET check-ins?since=cursor -------->| scans from other devices |<-- delta + next cursor ----------------| Idempotency is the whole trick Every scan gets a UUID generated on the device at scan time . The server puts a unique index on it and inserts-or-ignores: public function batchCheckIn ( BatchCheckInRequest $request , string $uuid ): JsonResponse { $results = collect ( $request -> validated ( 'check_ins' )) -> map ( function ( array $scan ) { $checkIn = CheckIn :: firstOrCreate ( [ 'client_uuid' => $scan [ 'client_uuid' ]], [ 'ticket_id' => /* resolved from scan */ , 'checked_in_at' => $scan [ 'scanned_at' ]], // ... ); return [ 'client_uuid' => $scan [ 'client_uuid' ], 'status' => $checkIn -> wasR

I spent the last few months building a new sparse fine-tuning method for MoE models called **USAF**. The goal was simple: if your GPU can run inference on an MoE model, it should also be able to fine-tune it. On my AMD RX 6750 XT (12 GB), I can fine-tune Qwen3-30B-A3B by training sparse expert weights and the router instead of adapters. The project is completely open source under the Apache 2.0 license. I'm not trying to build a business, sell anything, or monetize it in any way—I just wanted to share something I built that I think is genuinely interesting. I'd love to hear your feedback, especially from people working with MoE models. GitHub: https://github.com/tsuyu122/usaf submitted by /u/tsuyu122 [link] [留言]

I had just aced my mentor’s Docker exam, so of course I thought I understood containers. I had said all the right words: namespaces, cgroups, images, layers, PID 1, Kubernetes Pods. Then I typed my first serious command and Linux reminded me that knowing the nouns is not the same thing as building the thing. $ sudo unshare -p 1 test unshare: failed to execute 1: No such file or directory That was the opening scene. I had not even built anything yet. I had typed the flags wrong and accidentally asked unshare to execute a program called 1 . This was going to be less “implement Docker” and more “let the kernel correct my confidence, one error at a time.” v1: namespaces, or the first time PID 1 lied to me The first version was supposed to be easy: run a process in a new PID namespace and prove it sees itself as PID 1. So I ran the command the way I thought it worked: $ sudo unshare --pid bash # echo $$ 25184 That was not PID 1. That was just embarrassing. The rule I had missed is simple: PID namespaces apply to children. The process that calls unshare --pid does not magically become PID 1. You need to fork. The first child born into the new namespace becomes PID 1. So the working version was: $ sudo unshare --pid --fork bash # echo $$ 1 That one line changed the tone. I was inside a different process universe. The shell thought it was process 1. Signals felt different. Orphans came home to it. Then I ran ps , and got humbled again. # ps -o pid,ppid,comm PID PPID COMMAND 25310 25304 bash 25344 25310 ps That made no sense at first. I was PID 1, but ps was showing host-looking PIDs. The next reveal: ps does not ask the kernel some pure “what processes exist?” question. It reads files. If /proc still points at the host procfs, your tools will tell you the host story. So I remounted /proc from inside the namespace: # mount -t proc proc /proc # ps -o pid,ppid,comm PID PPID COMMAND 1 0 bash 7 1 ps That was when it clicked. The namespace did not become real to my eyes until /pr

Durante más de cuatro décadas, hablar de servidores era prácticamente sinónimo de hablar de arquitectura x86 . Desde los primeros servidores empresariales hasta la mayoría de los centros de datos modernos, Intel y AMD han dominado la infraestructura sobre la que funcionan nuestras aplicaciones. Sin embargo, algo está cambiando. De forma silenciosa, los principales proveedores de nube como Microsoft Azure están incorporando cada vez más procesadores ARM para ejecutar cargas de trabajo modernas. ¿La razón? No es únicamente el rendimiento. Es la eficiencia energética. El problema de los centros de datos modernos Cada vez que desplegamos una máquina virtual o un clúster de Kubernetes en Azure, detrás existe un servidor físico consumiendo energía. Ahora imaginemos un centro de datos con cientos de miles de servidores. Incluso una pequeña reducción en el consumo eléctrico por servidor representa un ahorro enorme cuando se multiplica por toda la infraestructura. Y no solo hablamos de electricidad. Menos energía implica: menos calor generado menor necesidad de refrigeración menores costos operativos menor huella de carbono Por eso la eficiencia energética se ha convertido en un factor estratégico para los hyperscalers (gigantes tecnológicos que poseen y administran infraestructuras de centros de datos masivas a nivel global). ¿Qué diferencia a ARM de x86? A grandes rasgos: x86 utiliza una arquitectura CISC (Complex Instruction Set Computing) , con un conjunto amplio de instrucciones complejas. ARM utiliza una arquitectura RISC (Reduced Instruction Set Computing) , basada en instrucciones más simples y optimizadas. Esto no significa automáticamente que ARM sea “más rápido”. Lo que sí significa es que puede realizar muchas cargas de trabajo consumiendo considerablemente menos energía. En otras palabras: ARM no busca ganar por fuerza bruta. Busca hacer más con menos. ¿Por qué ahora? Hace unos años, ARM estaba asociado principalmente a teléfonos móviles. Hoy la situación es muy

If you have ever wired up a cellular modem, a WiFi module, or a Bluetooth radio and typed something like AT+CGMR into a serial terminal, you have used a command language that is older than most of the engineers using it. The humble AT command set that still configures a huge share of today's connected hardware was born in 1981 , with a device called the Hayes Smartmodem. Four decades and billions of devices later, it refuses to die, and that longevity has a lesson in it for anyone building embedded systems. What AT actually stands for When Dennis Hayes and his company released the Hayes Smartmodem 300 in 1981, they faced a small but real design problem: how does a computer tell a modem the difference between a command to the modem and data to be sent down the phone line ? Their answer was an attention sequence. Every command line began with the two letters AT , short for attention , which told the modem to wake up and listen to what followed. ATD dialled a number, ATH hung up, and so on. It was readable, it was easy to implement on the microcontrollers of the day, and crucially you could type it by hand to debug a link. That simplicity is exactly why it spread. Competing modem makers cloned the Hayes command set to stay compatible, it became a de facto industry standard, and later it was formally captured in telecom standards. A convention that started as one company's pragmatic shortcut turned into the lingua franca of getting a device onto a network. From phone lines to the Internet of Things Here is the part that surprises people. The AT command set never retired when dial-up modems did. It quietly migrated into the components that make modern IoT possible. Cellular modules that put a device on a 4G or LTE network, from vendors like Quectel, SIMCom, and u-blox, are almost universally driven by AT commands. Classic Bluetooth and many WiFi modules expose an AT interface too. Even the ESP8266 and ESP32, the microcontrollers behind an enormous number of hobby and com

"Forward Deployed Engineer" went from a Palantir-specific title to one of the hottest roles in AI in about eighteen months. But nobody had actually counted the market, so I did. I pulled every open FDE role I could find from public ATS job boards (Greenhouse, Lever, Ashby) across 11 companies and analyzed all 292 of them. Here is what the data says. Who is hiring Three companies account for 250 of the 292 openings: Palantir: 95 (they coined the title, and still call many of these roles "Deployment Strategist") Databricks: 85 OpenAI: 70 Then a long tail: Cohere and Scale AI (13 each), Sierra, Writer, Modal, Baseten, Ramp, and Sardine. What it pays Of the 40 roles that disclosed a US pay band, the median ran $197K to $294K , topping out at $390K plus equity at OpenAI and Sierra, with a floor around $137K. That is senior-software-engineer money for a role a lot of engineers have never heard of. International and most Palantir roles did not publish bands, so the true market is likely even broader. Three things that surprised me 1. 98% of these roles are customer-facing. This is the defining trait. It is not a backend role with occasional meetings. It is an engineer who lives in the customer's world, and if that sounds terrible to you, this is not a role you would enjoy occasionally. It is the whole job. 2. The title is chaos. The same role goes by at least four names: Forward Deployed Engineer (152), Forward Deployed Software Engineer (58), AI or Deployment Engineer (43), and Deployment Strategist (36). If you only search one term, you miss most of the market. 3. The job descriptions undersell the technical bar. JDs emphasize customer-facing work, cloud (AWS/GCP/Azure), Python, and integrations. But SQL and algorithms show up in only about a third of them, even though every FDE loop I have seen tests live coding and SQL under time pressure. The description sells the breadth. The interview tests the depth. The other details Geography: about 48% USA, but genuinely global

If you want remote job data, you do not need to scrape HTML or sign up for anything. Four of the bigger remote job boards publish keyless public feeds. The catch is that they all speak different dialects, so the real work is normalization. Here are the endpoints and the traps. The four feeds RemoteOK returns its whole current board as one JSON array: GET https://remoteok.com/api The first element is a legal notice, not a job: they ask for a link back with attribution as a condition of using the feed. Skip element zero, and honor the attribution if you republish. Jobs carry salary_min and salary_max as numbers, tags, and ISO dates. Remotive has the friendliest API of the four, including server side search: GET https://remotive.com/api/remote-jobs?search=python&limit=100 Salary here is free text ( "$120k - $160k" ), so do not expect numbers. Attribution with a link back is required here too. WeWorkRemotely publishes RSS: GET https://weworkremotely.com/remote-jobs.rss Two quirks: the company name is not a field, it is baked into the title as Company: Role , so split on the first colon. And useful data hides in nonstandard tags like <region> , <skills> , and <category> that generic RSS parsers drop on the floor. Himalayas has a proper paginated API with a surprisingly deep catalog (100k+ listings): GET https://himalayas.app/jobs/api?limit=100&offset=0 It gives structured minSalary / maxSalary with a currency and period, seniority arrays, location restrictions, and even timezone restrictions as UTC offsets. Dates are epoch seconds, not ISO strings. The normalization layer The row schema that survived contact with all four sources: { "source" : "Remotive" , "title" : "Senior Backend Engineer" , "company" : "Acme Corp" , "tags" : [ "python" , "aws" ], "salaryMin" : null , "salaryMax" : null , "salaryText" : "$120k - $160k" , "location" : "Worldwide" , "postedAt" : "2026-07-03T20:01:13.000Z" , "applyUrl" : "https://..." } Rules that mattered in practice: Keep both salary sh

Why Your SOE Resume Needs a Structural Overhaul Chinese state-owned enterprises (SOEs) often have deep hierarchical structures and a culture of collective achievement. But Western tech companies want to see individual impact, autonomy, and data-driven results. Continuing to lead with your former employer's prestige or your rank (e.g., "Senior Engineer Grade 7") wastes valuable space. The solution: reshape every section to answer the question "What did you personally accomplish with data?" The Core Shift: From Hierarchy to Impact In a Chinese SOE resume, it's tempting to list departments you led or teams you oversaw. In a Western senior data scientist resume, focus on the problems you defined, the algorithms you deployed, and the revenue, cost savings, or user metrics that improved. For example, instead of "Led the data analytics team of 10 people," write "Designed and deployed a demand-forecasting model that reduced inventory costs by 15% (¥12M annually)." Three Resume Sections That Require Full Rewriting Professional Summary: From 'Accomplished Engineer' to 'Data Science Leader' Start with your total years of experience, your technical stack, and the types of business problems you solve. Example: "Senior Data Scientist with 10+ years applying machine learning to supply chain and logistics. Expertise in Python, TensorFlow, and Spark. Reduced operational costs by 15-30% through predictive models deployed at [SOE name]." Work Experience: From Role Descriptions to Metric-Driven Bullets For each role, list 3-5 bullets. Every bullet should have a verb, a task, a technology (if relevant), and a quantified result. Avoid vague phrases like "responsible for." Use specific numbers: "Improved forecast accuracy from 70% to 85% by building an ensemble of ARIMA and XGBoost models." Education & Certifications: Emphasize Transferable Skills Your Chinese degree is fine, but add relevant certifications (AWS, TensorFlow, Coursera) to show adaptability. Consider a "Technical Skills" se

This is my first post here, so I'm going to use it as an introduction. I'm Usman, a software + data engineer who primarily works with data pipelines, backend systems. Not a huge fan of frontend development though. Although I do what I can, projects honestly feel incomplete without them, because at the end of the day you do have to showcase a working end to end system when you build something. I'm here after dozens of incomplete personal projects, and projects that never even got past the design phase, you know the drill. Procrastination and imposter syndrome kept stopping me from taking the next step, but I'm here now, gotta keep myself in check fr. I was scrolling through LinkedIn the past few days, and oh my god, the amount of AI-related brain rot there. Every single post written by AI, telling you how to use AI and how not to use AI. I mean I get it, yeah, the paradigm is shifting and AI is essential to development, but where are your personal anecdotes, stuff you solved, stuff you learned, the challenges you faced, how you overcame them. You know what maybe it's my fault, it's my algorithm after all. Anyway, here I am, looking to interact with like-minded engineers and learn from them. I'm also going to post regularly about my progress and what I am building, even though I have quite a bit of experience, and have built and contributed to large-scale production systems and pipelines, I'm going to start with something small, so I can stay consistent and keep myself in check. Software engineering fascinates me a lot, and there are so many domains that I wish to explore and have explored like game development, data engineering, web/app development. My significant other is graduating in a few days, and I'm thinking of making a small game for her, alongside which I'll be working on a small sales lead enrichment pipeline. Hoping to showcase my work and document it publicly, and hoping to get to know and learn from you all! Also, I'd love to know your thoughts on the am

Mistral AI, which offers some open source AI models, has raised significant funding since its creation in 2023, with the ambition to “put frontier AI in the hands of everyone.”

Ever wondered why sometimes the simplest things throw a wrench in our beautifully crafted code? I recently had a realization that hit me like a ton of bricks: the bottleneck could literally be the air in the room. It sounds absurd, right? But let me take you on a little journey through my recent experiences that led me to this conclusion. The Setup: A Frustrating Week Just a few weeks ago, I was knee-deep in a project using Python and TensorFlow to build an AI model for image classification. I was feeling pretty confident, you know? I had my dataset prepped and cleaned, my model architecture designed, and I was ready to train. But then, out of nowhere, my training took an eternity. I was kicking myself for not optimizing my code, but something just felt off. I started checking everything from my training loop to the data pipeline. I even considered that maybe I had some rogue semicolons in my Python code—classic mistake, right? But no, everything seemed fine. Then, in a moment of clarity, I realized my laptop was struggling to keep up. The fan was roaring like it was auditioning for a heavy metal band. It hit me that maybe, just maybe, the problem was my environment—specifically, the air conditioning. Environment: The Unsung Hero I’ve learned that environment can have a huge impact—like, why didn’t I think of this sooner? I had been training my model in my home office, where the temperature was rising faster than my enthusiasm for debugging. I decided to take things to the next level and moved my setup to a cooler room. And guess what? My training speed improved significantly. It turned out that my laptop was throttling itself to prevent overheating. This was my "aha moment." It was a reminder that sometimes the bottlenecks in tech aren’t just about code or hardware; they’re about the conditions we create for them. The Code: Finding Efficiency Once I had a handle on my environment, I dove back into my code. I had learned the hard way that performance optimization is

I spent over 20 years working in industrial maintenance as a boilermaker. Most of that time was in refinery shutdowns and turnarounds—high-pressure environments where systems either hold or fail. There is no “mostly working” in that world. That experience has shaped how I approach software development. ⸻ I’m not just “learning to code.” I’m building systems. I’m currently working on transitioning into web development, but I’m not approaching it as a tutorial exercise I’m building real projects from day one—and documenting the process as I go. Not theory. Not exercises. Actual systems that are meant to run. ⸻ What I’m building right now A portfolio site that behaves like a system (kmwebdev.me) This isn’t a “personal website” in the usual sense. It’s a live system under controlled change. I treat it like industrial maintenance work: versioned updates instead of redesigns small, controlled changes only tracking what changed and why stability over aesthetics Nothing gets changed without intent. ⸻ A production-focused email framework (Skeleton Framework) Alongside the portfolio work, I’m building a separate system for HTML email development. Email is one of the most constrained environments in web development. Rendering is inconsistent, standards are partial, and modern CSS support is unreliable across many clients. So instead of fighting those constraints, I’m building a framework specifically designed around them. The focus is simple: predictable rendering in real-world email clients It’s still early, but it’s being developed with production use in mind—not experimentation. ⸻ The way I work hasn’t changed—only the tools have In industrial maintenance, you learn a few hard rules: don’t assume—verify don’t scale chaos don’t change more than you can test document everything that matters So I carry that directly into development: versioned releases (v1.0, v1.3.6, etc.) controlled incremental changes explicit documentation of limitations real-world testing across environmen

Everyone is talking. Almost no one is thinking. Your morning starts with a vibration, then another, then a pile-on. Slack wants a status update. Instagram wants your face. A group chat you muted in March has resurrected itself to debate brunch. By 9:07 am you have done the emotional labor of a small call center and you have not finished your coffee. We call this being connected. A more honest word is being farmed. The internet does not pay you for your best ideas. It pays you for your fastest replies. Availability became a virtue, then a job description, then a personality. Silence got rebranded as flaking. I decided to rebrand it back, but with better tools. Not the aesthetic digital detox where you post a grainy photo of trees with “offline” in lowercase and then lurk from a finsta. I mean real disappearance. The kind where your work still ships, your people still feel held, your money still moves, and you are simply not there to watch the conveyor belt. You do not need to quit. You need to quit performing presence. The Attention Tax Is Real, and You Are Overdrawn Every ping is a micro-withdrawal from your nervous system. You pay in focus, in mood, in the ability to finish a thought. Platforms collect the interest. Researchers at UC Irvine have been tracking this for years. After an interruption it takes roughly 23 minutes to get back to the original task. The average knowledge worker gets interrupted 80 to 90 times a day. Do the multiplication and you realize most people never actually get back. They just start new half-tasks until bedtime. We treat this like a willpower problem. It is an architecture problem. Your phone is designed to win. You will not out-discipline a trillion-dollar attention refinery. You have to change the plumbing. Silence is not doing nothing. Silence is compound interest for your brain. Ten uninterrupted minutes today becomes a finished essay next week becomes a body of work next year. The people who seem calm are not morally superior.

Some Apple devices are about to get much more intelligent, while others are getting left behind.
