Most recommendations I’m seeing are for generating presentations from a topic, but I already HAVE the content. Problem is it’s usually: messy notes meeting transcripts random docs giant walls of text Main thing I want is help turning all of that into slides that are actually readable. Does anything handle that well right now? submitted by /u/ragsyme [link] [留言]

Sorry Anker: JMGO now makes my favorite flagship portable projector. The N3 Ultimate is an excellent portable 4K projector that defeats moderate ambient light at severe placement angles and can rival more expensive home theater installations at night. After a few weeks of testing, I think the raw adaptability exhibited by the JMGO's N3 Ultimate […]

June 7, 2026. Dennis Kim, ex-CEO of Cyworld, CEO of BetaLabs https://github.com/gameworkerkim/vibe-investing https://github.com/gameworkerkim/CYBER-THREAT-INTELLIGENCE-REPORT Prologue: Two Incidents That Shook South Korea in 2026 In early June 2026, a data breach exposed the personal information of 5 million users of TVING, the largest OTT service in South Korea. The leaked data was extensive: IDs, names, birth dates, gender, CI (connection information), DI (duplicate registration verification information), mobile phone numbers, emails, refund account numbers, passwords, and more. The parent company, CJ ENM, saw its stock price plummet 3.44% in a single day, and investigations by the Personal Information Protection Commission and KISA were launched. But behind this incident hid another shocking fact. TVING's GitHub repository had an AWS access token hardcoded and publicly exposed. It was a stark reminder that a single cloud private key accidentally committed by a developer can jeopardize an entire company's infrastructure. These two events seem like different stories on the surface. Yet here I want to ask one common question: Who protects our generative AI, our LLM systems? Part 1. The Age of Vibe Coding: Security Takes a Backseat Recently, natural language-based programming using LLMs, the so-called "Vibe Coding" trend, has exploded. Generative AI coding assistants dramatically accelerate development speed. But behind this speed lies serious security risks. According to Veracode's 2025 GenAI Code Security report, 45% of code generated by LLMs contained security vulnerabilities. More concerning, developers place excessive trust in AI outputs and show behavior patterns prioritizing speed over vulnerability verification. Kaspersky's 2025 report revealed even more shocking findings. A vulnerability in the popular AI development tool Cursor (CVE-2025-54135) allowed attackers to execute arbitrary commands on a developer's machine, and a vulnerability in the Claude Code a

For the past year I worked on a remote contract with a US tech company. Paid in USD, ultimately needing Korean won. Simple, right? Then a year in, I actually reconciled what landed in my account. The exchange rate had gone up — and yet my real received amount was lower than I'd expected. I traced it, and money was leaking at every step of the transfer path I hadn't been watching. This is what I learned switching routes over that year: from a direct bank wire to Wise, the real cost difference, and one right buried in my contract. If you're a freelancer or contractor in any country earning USD from abroad, this should save you something. Money leaks in more than one place Getting USD from overseas into local currency looks like one step. It's actually at least four: The wire fee from the US bank, through correspondent banks, to the receiving bank. The exchange rate the receiving bank applies — this is the big one. The receiving fee on the destination side. A hidden "lifting charge" some correspondent banks skim. The largest is the rate. Banks quote two rates, and the "buyer rate" applied when an individual sells dollars is worse than the mid-market reference — typically a 1.5–2% spread . On $1,000, that's $15–20 gone to the rate alone. That number looks small. Accumulated over a year, it stops looking small. Route A — receiving directly through a major US bank My first setup was the simplest: the company wired USD to my US bank account, and I wired it on to my Korean bank. I picked this at contract start without much thought, assuming the client would conventionally cover fees anyway. (Lesson one: specify the transfer method, route, and who pays in the contract. ) The problem was the bank's exchange rate. It applied the buyer rate straight up, with a wider-than-usual spread versus mid-market — plus a send fee, plus the Korean receiving bank's fee. I only noticed months in. Comparing statements, there was a steady 2–3% gap between the won I'd expect at mid-market and t

Setting up a 10-page marketing site Count the tools. You reach for Next.js or Astro. You run npm init . There's a bundler config. PostCSS for Tailwind. A Netlify account. A GitHub repository. Environment variables for the CMS token. A build hook URL from Netlify, pasted into the CMS webhook settings so content publishes trigger a rebuild. Maybe a CI configuration file. For a 10-page marketing site. The honest question: does a 10-page marketing site need any of this? For most content-focused sites, the answer is no. How we got here The JAMstack movement was right about the fundamentals. Pre-generated static HTML served from a CDN is faster, cheaper, and more secure than server-side rendering at request time. Netlify and Vercel made this genuinely accessible. The developer tooling that emerged around it was designed well. The problem is that the tooling was designed for applications — large JavaScript codebases with complex component trees, client-side routing, and sophisticated build requirements. It's good tooling for that use case. It became the default for everything, including content sites that have no more complexity than a Markdown file and a CSS stylesheet. When the tool doesn't fit the problem, you inherit the cost of the tool without the benefit. What the build pipeline actually costs Setup time. Getting a new project from blank to deployed with a modern build pipeline takes a few hours if you know the stack, longer if you're making decisions. Framework version, bundler config, PostCSS, Tailwind setup, environment variable management, deploy configuration. That's before you've written a single line of page-specific code. Maintenance surface. Every dependency is something that can break. Node version compatibility, framework major version upgrades, bundler updates, plugin compatibility matrices. A project set up in 2022 may require non-trivial work to update in 2026. For a client site, that maintenance either falls on your agency or accumulates as technical

Imagine you are building a cloud-native backend for a high-frequency trading platform or a core banking ledger. To ensure mathematical immutability and prevent silent data tampering, compliance mandates that every transaction for a specific financial account must be cryptographically chained. This means the signature of Transaction #50 must explicitly include the cryptographic hash of Transaction #49. You cannot sign them out of order, and the backend is strictly responsible for generating and validating this chain. This introduces a massive distributed systems headache: How do you enforce strict, sequential ordering while maintaining the concurrency required to scale a modern cloud architecture? Let's walk through the evolution of this system, deconstruct exactly how the standard event-driven approach fails in production, and examine the Staff-level architecture required to fix it. Phase 1: The MVP & The Database Bottleneck In the early days, traffic is low. An account might see one transaction every few minutes. The "Happy Path" is simple: The API receives a deposit request for Account A. The API queries Postgres for the last_signature_hash . The API computes the new hash in memory: SHA(last_hash + new_transaction_data) . The API writes the new transaction and updates the state. The Pitfall: The Thundering Herd To prevent two concurrent requests from reading the same previous hash, you wrap the database operation in a pessimistic lock: SELECT ... FOR UPDATE . This forces the database to serialize requests at the row level. When a massive partner bank initiates a bulk sync, dumping 5,000 transactions for a single corporate account onto the API in two seconds, 4,999 concurrent threads immediately hit the FOR UPDATE lock and block. The database connection pool is instantly exhausted, latency spikes platform-wide, and the MVP dies. The Insight: The database must be your last line of defense, not your primary queueing mechanism. Contention must be solved upstream in me

Start here This post assumes you have a project and you're trying to pick a tool. It skips the marketing and goes to the technical and economic decisions that actually matter when you're doing the evaluation. All three of these platforms — Contentful, Sanity, and SleekCMS — are used in production by serious teams. The comparison is not going to tell you one of them is bad. It's going to tell you which scenarios each one is genuinely suited for, so you can match your project to the right tool. The three platforms at a glance Contentful is an enterprise-grade headless CMS with a long history of production deployments, a large ecosystem of integrations, and pricing that becomes significant at scale. It's the established choice for large organisations with existing Contentful investment. Sanity is a developer-first headless CMS with a flexible schema system, real-time collaborative editing, and GROQ — a query language purpose-built for content graphs. It has a strong developer community and a genuinely modern developer experience. SleekCMS is a headless CMS with an integrated static site builder. Structured content with REST and GraphQL APIs, a TypeScript-native client library, and the option to generate and deploy a static site from the same content models without maintaining an external frontend stack. Content modeling All three support structured content modeling. The differences are in how you define models and what the system supports natively. Contentful uses a GUI-based model builder in the dashboard. You create content types and add fields through a point-and-click interface. Solid for teams who prefer a visual setup; less ideal if you want models version-controlled as code. Sanity defines schemas in TypeScript or JavaScript config files — committed to your repository, version-controlled, and composable like code. This is Sanity's strongest differentiator for teams who think in code-first workflows. The schema definition is expressive and the TypeScript integrat

The brief Small professional services firm. Needed a clean marketing site: homepage, services section with individual service pages, about page, a blog, and a contact form. Timeline: tight. Budget: fixed. The kind of project where the question isn't whether you can build it — it's whether you can build it without spending three days on project scaffolding before writing a single line of content-specific code. This is what that afternoon looked like. One command to start The cms-sync is the entry point. One command creates the local workspace and starts the file watcher: npx @sleekcms/sync --token YOUR_AUTH_TOKEN On first run, the workspace appears with three files before you've written anything: my-site/ ├── CLAUDE.md ├── AGENT.md └── .vscode/ └── copilot-instructions.md These context files are the key. CLAUDE.md for Claude and Claude Code. AGENT.md for GitHub Copilot in agent mode. .vscode/copilot-instructions.md for GitHub Copilot in VS Code. Each contains the complete SleekCMS site-building reference — file naming conventions, model syntax, template helpers, field types, content format. Open the workspace in Cursor (or VS Code with Copilot, or Claude Code). The AI already knows how to build a SleekCMS site. No setup prompt, no pasting documentation. The prompt We kept it realistic — not a paragraph of precise technical specification, but the kind of description you'd give a developer on a call: Build a professional services marketing site with: - A homepage with a hero section, services overview, client logos, and a contact CTA - A services page listing all services, and individual service detail pages - An about page - A blog with individual post pages - A shared header and footer - A contact form - Tailwind CSS styling - SEO meta tags on every page What the AI generated The output was a complete set of working files: models/pages/_index.model models/pages/services.model models/pages/services[].model models/pages/about.model models/pages/blog[].model models/page

SQL tuning is the process of making a database query run faster and cheaper — cutting response time while minimizing the system resources it burns. Here's the playbook I actually use, from "this query is slow" to "this query is fixed," with the traps that bite people in the middle. The loop Tuning is iterative. The shape is always the same: Identify the problem. Find the slow query (logs, profiler, or user feedback) and measure a baseline — execution time and resource usage. You can't claim an improvement you didn't measure. Analyze & rewrite. Review the SQL for redundant joins, unnecessary work, and complex subqueries. Tighten the WHERE , select only the columns you need, convert subqueries to joins where it helps. Read the execution plan. Understand how the engine actually runs the query; find inefficient join orders and needless full scans. Revisit indexes. Evaluate whether existing indexes help; add or restructure as needed. Consider schema changes. If a column is updated so often that indexing it hurts, split it out. Sometimes the model is the bottleneck. Tune settings/hardware if it comes to that. Re-test and repeat. Apply changes, re-check the plan, confirm the gain, monitor. Reading an execution plan The execution plan shows how the DB will run your query — table scans, index access, join methods. Read it well and you can pinpoint where the time goes. Most engines expose it: EXPLAIN (MySQL/PostgreSQL), EXPLAIN PLAN FOR (Oracle), SET SHOWPLAN_ALL ON (SQL Server). Operators to know: Full Table Scan — reads every row. Happens when there's no suitable index, or the query can't use one. Index Scan — scans via an index; usually cheaper than a table scan. Index Seek — jumps to specific key values; very efficient, reads only the rows it needs. Nested Loops / Hash Join / Merge Join — the three ways to join two tables (more below). Sort — orders data; excessive sorting is a common performance drag. Three numbers that matter: Cost — estimated resources a step will cons

A real look at the platform everyone's calling "the writer's alternative to Medium" Let me be...

AWS recently announced ExtendDB, a DynamoDB-compatible adapter that lets developers use the DynamoDB API with different storage backends, starting with PostgreSQL. The project supports existing SDKs and tools without modification, giving teams greater flexibility to run DynamoDB-style workloads outside of native DynamoDB while maintaining compatibility with current applications and workflows.

Chinese models now account for 61% of global LLM token consumption. DeepSeek, Qwen, GLM, and Doubao consistently dominate the global top 10 on OpenRouter. But for developers outside China, accessing them is painful — no English docs, no international payment, confusing pricing. I tested all 6 major APIs. Here's what I found.

This week the agent economy got another "settlement layer." Actually it got three. They don't agree on what the word means, and one of them raised $8M to keep saying it. So instead of a new argument, here's the map we drew across the week - four honest meanings of "settlement," what each one is genuinely good at, and the one job that none of the funded products this week actually cover. This is a recap post. If you read along this week, you've seen the pieces; this is the through-line. If you didn't, this is the whole week in one place. The week's biggest signal: a funded word The freshest data point is AEON's raise - $8M from YZi Labs to build, in their words, a settlement layer for the agentic economy. Under the hood it's an x402 facilitator on BNB Chain, routing agent-to-merchant payments across a very large merchant network. That is a real and useful thing. It is also, very specifically, payment : an agent sends a stablecoin to a seller it has chosen, value moving one direction to a known recipient. It sits next to two others that shipped recently and also wear the word: Circle's Agent Stack + Nanopayments moves gas-free USDC down to a millionth of a dollar, batched across chains. That's settlement as machine-speed micropayment - still one asset, still one direction, optimized for volume and tiny amounts. Fireblocks' Agentic Payments Suite puts a custodied vault between intent and execution: the vault holds funds and releases them when policy says so. That's settlement as custody-and-release - someone you trust holds the money in the middle. Three products, three meanings: route a stablecoin, micropay at machine speed, custody-and-release. All three are legitimate infrastructure. Builders should use them where they fit. The meaning none of them cover Here's the job that falls through the gap between all three: two agents that don't trust each other, swapping different assets, possibly across two chains, with no one holding the funds in between. A payment rail as

Not long ago, I saw articles analyzing how Chinese people obtain US model API at low prices through non-compliant means, and also saw Chinese developer sharing their Vibecoding experiences. Very interesting, it seems the outside world is finally starting to understand our daily lives. I want to share a complete perspective here: how an ordinary Chinese student, also developer, accesses the most advanced US models. Including the evolution of various access methods over 4 years, the practical experience of using various methods, and the problems encountered, etc. I will try to describe it objectively and truthfully. Let's start by going back to November 2022, when OpenAI released "ChatGPT": Phase 1: "ChatGPT" ChatGPT was released, and it was big news in China, even though it predictably did not serve China. Even though I was still a high school student at the time, I was still interested, after all, it was the first time I saw something truly close to "intelligence". How to access it? There are two types of services generally inaccessible in China: one is that the GFW blocks the domain name or IP of the service, and the other is that the service provider refuses IPs from China. ChatGPT is both. The solution is also simple, use a proxy, which is a basic skill for Chinese developers. In addition, registration requires receiving a SMS verification code. Chinese mobile numbers are definitely not an option, but the solution is not difficult either, find a verification code receiving platform, use a temporary number to receive the verification code. Thus, I started using ChatGPT, which now seems like a model that speaks slowly and is not very smart. Phase 2: "Mirror Sites" During high school, I didn't have many scenarios to use ChatGPT. I started using AI more when I entered university, as AI is well-suited for dealing with those annoying assignments. It was the second half of 2023, and there was a new way to access it: mirror sites. "Mirror sites" originally referred to an

If you've been running local models/apps across more than one machine for any length of time, you've probably noticed that everything is served over plain HTTP, whether its the backend llm apis, the front end sites, or whatever other stuff you've tossed in: most of it is HTTP-only out of the box, no TLS option anywhere in sight. On one machine thats usually fine since its all loopback, but the second you spread apps across a few different computers ( which some of us do ), every prompt and every response starts crossing your LAN in plaintext. Is plaintext on your own LAN a huge deal? Honestly... a lot of folks would say it's probably low risk. But the moment you've got guests, other people's phones, or random IoT junk sharing that network, your prompts and the models responses flying around in the clear are more exposure than you'd probably be comfortable with if you sat down and thought about it. So, with that said- I figured Id write up how I've dealt with that, because the textbook answer ( certs ) is annoying enough on a local network that I think a lot of folks just dont bother. This is a lot easier, especially on something like a mac where you can make sure it kicks off automatically via launchd . Why not just do TLS The "correct" answer is to put TLS on everything; HTTPS everywhere. And you can. But walk through what that actually means on a home network full of mixed machines: You stand up your own little CA, then sign a cert for each host ( unless you want to deal with some code just straight up rejecting the cert ). You install and trust that CA on every client. Every browser, every OS trust store, and ( this is the annoying one ) every app that ships its own trust store and ignores the system one. Plenty of python and node apps do that. A lot of these local LLM apps dont even expose a TLS option, so to add it you front them with something like nginx or Caddy, which is now another moving part on every box ( Setting up Caddy is what convinced me to go this

idk maybe this is obvious to people already working in bigger teams, but the AI coding tool cost thing feels like early cloud all over again. Everyone keeps saying tokens are getting cheaper, which is true, but then somehow companies are still freaking out about AI bills. And I think the reason is pretty simple: people are treating these tools like normal SaaS seats when they are really more like metered infra. Like with a normal dev tool you kind of know the cost. X users, Y dollars per month, done. But with agentic coding tools one small request can quietly turn into a bunch of model calls, context loading, tool calls, retries, verification, more retries, etc. From the user side it looks like “fix this bug” or “write this function” but underneath it may have done a whole mini workflow. And then there is the other cost which I feel people don’t talk about enough: reviewing the generated code. Sometimes the code works but it adds weird duplication, misses existing abstractions, or creates stuff that someone has to clean up later. So the bill is not just tokens. It is also review time + maintenance + future tech debt. Not saying these tools are bad btw. I use them too and they are obviously useful. But it feels like the industry is moving from the fun phase of “look what this can do” to the boring phase of “who is paying for all these calls and did this actually ship anything useful?” Curious if teams are actually tracking this properly yet. Like cost per PR, cost per resolved ticket, cost per workflow etc. Or is it still mostly hidden under “AI productivity” and vibes. submitted by /u/Old_Cap4710 [link] [留言]

“A self-indulgent weekend divergence from the usual Vektor memory business content. Consider what happens when you give a developer two days off, unlimited internet archive access, and too many ideas crammed into one article." Writing this article began organically. Which is a funny thing to even have to say in 2026. What does organic even mean now? I don't care, man; I just want to be free to express myself, man. I did not write this on a mechanical typewriter. I wrote it on a PC with my stubby index fingers running Windows software that, miraculously, does not blue screen every ten minutes anymore. It only took Microsoft thirty years to pull that off. To the left sits an analog record player with some secondhand Yamaha bookshelf speakers I found at a charity shop; to the right of me sits a modern dark wood-paneled Zen PC case, a processor that would have occupied an entire room thirty years ago, and a GPU that can synthesize gargantuan piles of AI slop or brilliant code in roughly ten seconds flat. And yet, for all that raw power, it still comes down to an algorithm. It always has. The Sharper Image and the Death of Wonder When I was a kid I used to walk into The Sharper Image store at Faneuil Hall Marketplace in Boston and just stand there. Looking at technology I could not afford while the staff watched me carefully to make sure I did not break anything. I also grabbed some bright coloured rock salt candy; I loved stuff, some core memories right there. That feeling of picking up a piece of technology and not quite knowing what it did, like a ten-year-old ape holding something from another civilisation, you cannot replicate that in a sterile Apple store. The technology is better now. Genuinely better. Faster, smaller, more capable than anything those shelves held. But the sense of wonder at the unknowable object is completely gone. Everything is explained before you touch it. Every product has a thirty-second video, a Reddit thread, a YouTube teardown, a comparis

I work in IT admin for a major company. Started teaching myself AI automation tools in my own time. Applied them to my workload, my output doubled, got noticed and promoted. Became the go to person for AI integration across departments. But here’s the part that sits heavy with me. Once leadership saw what AI could do, they started looking at headcount differently. People who had been there 10, 15 years. Gone. Not because they did anything wrong. Just because a system could now do their job cheaper. I benefited from knowing AI early. Others paid the price for not knowing it yet. Is that their fault? The company’s fault? Just the way progress works? Genuinely asking because I don’t have a clean answer. submitted by /u/PickYourJawnUp [link] [留言]
