The man is said to be doing well in a Frankfurt hospital.
My 2nd article this week, I'm supposed to keep it to just once per week but whateverrr, I've had this...
Microsoft is testing a cleaner version of the Windows 11 search menu that strips it of recommended content and ads. In a blog post on Monday, Microsoft announced that it's rolling out the decluttered Search Box to Windows Insiders in the Experimental channel as the company looks to regain trust with users and fix Windows.

OnePlus and its parent company, Oppo, plan to announce in the coming days that OnePlus brand will be leaving the US and European markets, according to a machine translation of a WinFuture report. Should the exit actually happen, it will mark a conclusion to months of rumors about the future of OnePlus. Android Headlines said […]
Hey what's up guys👋🏻 Remember our last Perfect Circle challenge? We had some amazing attempts! While...
In the fast-moving world of cryptocurrency, market data changes every second — prices fluctuate, trades execute, and volumes shift continuously. Capturing this stream of real-time data and transforming it into meaningful insights requires a robust and scalable pipeline. In this project, I built a complete real-time crypto market data pipeline that captures, streams, stores, and visualizes live data from Binance using PostgreSQL, Debezium, Kafka, JDBC, and Grafana. The goal was to design an architecture that not only moves data instantly between systems but also keeps it queryable and monitorable in real time. What began as a simple Binance data extractor evolved into a production-grade CDC (Change Data Capture) workflow capable of detecting every database change, streaming it through Kafka, storing it in a sink database, and visualizing it live on Grafana dashboards.
Apple’s revamped Siri is more than a voice assistant; it’s now the backbone of the iPhone user experience. You can try it now through the iOS 27 public beta.
Rendering a big image on iOS is one of those things that looks trivial until your app gets killed by the OS mid-export. CGContext , draw, makeImage() , done — except the moment the output gets large, that innocent-looking pipeline quietly asks for gigabytes of RAM and iOS terminates you. I hit this wall building Mozary , an iOS app that packs 100+ photos into a single giant picture (a photo mosaic). In v1.1.0 I finally killed the "high-resolution export crashes with out-of-memory" bug for good. The fix: stop putting the canvas in RAM at all. Put it in a memory-mapped file and let the OS page it to disk. RAM usage dropped from "4.8 GB, please die" to a few dozen MB, flat, regardless of output size. This post is the walkthrough — with the actual Swift. If you've ever seen Core Graphics blow up on a big image (mosaics, collages, stitched panoramas, high-res rendering — same trap), this is for you. TL;DR A non-compressed bitmap costs 4 bytes/pixel . A 1.2-gigapixel image = ~4.8 GB of RAM just for the canvas. CGContext(data: nil, ...) allocates that in RAM. context.makeImage() then copies it again . Double death. Back the canvas with a memory-mapped file ( mmap ). Writes transparently page out to disk and don't count against your app's memory footprint . Wrap that same mapping in a CGImage via CGDataProvider — zero copy — and stream it straight to a JPEG on disk. Never call makeImage() . Decode source tiles at their draw size , not full size. Because you now spend disk instead of RAM: add a free-space pre-flight check and clean up temp files after a crash. Let's dig in. The problem: "compressed file size" is a lie about memory Mozary lays photos out on a grid. A typical high-res export is a 200 × 267 grid with each tile drawn at 150px : width: 200 × 150 = 30,000 px height: 267 × 150 = 40,050 px That's ~1.2 gigapixels . Here's the part people underestimate: the final JPEG is only a few hundred MB to ~2 GB because JPEG is compressed . But while you're drawing, the canvas i
Most teams test email by not testing it. The send path gets a mock — expect(transport.send).toHaveBeenCalledWith(...) — and everyone agrees that's "good enough." The receive path gets skipped entirely, because there's no honest way to assert on a real inbox from a test runner. So the one part of your system that talks to the outside world over an unreliable, asynchronous, third-party channel is the part with the least coverage. That's backwards. The reason email is hard to test isn't the sending. It's the asserting . You can fire POST /messages/send all day, but to prove the message actually left, rendered correctly, and arrived with the body you expected, you need a real mailbox you control — one you can read programmatically and throw away when the run finishes. Shared Gmail test accounts almost get you there, but they bring OAuth on the runner, catch-all races between parallel workers, and a 90-day token that expires the night before a release. This post is about a different fixture: a disposable Agent Account created at the start of a CI run and deleted at the end. You mint a real mailbox per run (or per test), point your application at it, send and receive real mail, assert on the actual message body, and tear the whole thing down. No OAuth. No shared inbox. No leftover state. What an Agent Account gives you here An Agent Account is just a Nylas grant with a grant_id . That's the whole trick, and it's worth saying plainly because it's what makes this pattern cheap: an Agent Account works with every grant-scoped endpoint you already know — Messages, Drafts, Threads, Folders, Attachments, Webhooks. There's nothing new to learn on the data plane . If you've ever called GET /v3/grants/{grant_id}/messages , you already know how to read a test inbox. The difference from a normal grant is provisioning. A regular grant needs a real human to complete an OAuth flow. An Agent Account is created with a single API call — no OAuth screen, no refresh token, no human. It's a m
Most "AI email agent" demos quietly assume the agent answers everything. Point a model at the inbox, generate a reply, send it, repeat. That's a fine loop right up until the model hits a message it shouldn't touch — an angry customer, a legal question, a refund the agent has no authority to approve — and confidently fires off a reply anyway. The expensive failures in agent email aren't the threads the agent gets wrong. They're the threads the agent answers at all when it should have stepped back. So let's build the part that steps back. Not the classifier that decides a message is risky — that's triage , a separate problem. This is the handoff : once something flags a thread as "needs a human," how do you actually pull the whole conversation out of the agent's reach, park it where a person can find it, and make sure the agent keeps its hands off until that person clears it? I work on the Nylas CLI, so the terminal commands below are the exact ones I reach for when I wire up an escalation path. Every operation gets the two-angle tour: the raw curl call and the nylas command that does the same thing. What the handoff actually needs An Agent Account is, underneath, just a Nylas grant with a grant_id . That's the spine of everything here, and it's worth sitting with: there is nothing new to learn on the data plane. The same grant-scoped endpoints you already use — Messages, Threads, Folders, Drafts — work against this grant exactly the way they work against any Gmail or Microsoft grant you got through OAuth. So the escalation path isn't some special agent feature. It's three plain operations you already half-know: A place to put escalated threads. A custom folder — call it Needs human — that lives alongside the six system folders every Agent Account ships with ( inbox , sent , drafts , trash , junk , archive ). A way to move the whole thread there. Not one message — the thread . A reply is just the latest message in a conversation; a reviewer needs the full chain. A way
