UN panel says 'AI is neither inherently good nor bad,' but better safeguards around it are needed.

Smart speakers have spent the past few years searching for a compelling second act. Beyond music, timers, and controlling your lights, they've struggled to justify taking up space on the kitchen counter. AI promised to change that. Amazon debuted its new hardware powered by a revamped Alexa last fall, and now it's finally Google's turn. […]

I saw an issue today on a fairly popular project (better-auth, see the link to the issue attached). No repro, no context, just a wall of caps and profanity ending in "fuck you". The maintainers ship this for free. People run production businesses on top of it, for free. And the thanks is someone raging into a text box because a minor bump cost them an afternoon. I maintain and contribute to a few projects myself, so this hits a nerve a bit. Something people don't see from the outside: it's not enough to know how to build the thing. You also have to know how to defuse a thread where someone's insulting you and not fire back, even though most of us aren't paid for any of it, let alone the work of staying civil while being told to get fucked. I'm not pretending breaking changes don't cause real pain (that's what the issue is about). But I keep coming back to a boundary question: if you're not paying for it, do you actually get to demand anything?

After Trump's claims, Tylenol usage dropped during pregnancies.

The panelists explain the realities of running AI systems reliably at scale. While building models is solved, maintaining production databases under constant pressure is not. They discuss the emerging architectural decisions separating teams that scale gracefully from those facing catastrophic outages, and what engineering leaders must rethink today.

Papa Johns is spying on people’s buying activities to predict when they are low on food: The pizza chain recently tapped NBCUniversal, Instacart and the dentsu-owned media agency Carat for help reaching consumers when they’re low on groceries—and thus more likely to be swayed by a mouth-watering ad. The idea is to reach hungry consumers by “knowing what is in their fridge without being too creepy,” said Carrie Drinkwater, chief investment officer at Carat. To achieve that goal, NBCU and Instacart created a custom audience of shoppers who regularly purchase grocery staples on Instacart, such as eggs, milk, meat and produce. Based on that data, Papa Johns can determine which days of the week certain consumers are likely to run out of groceries and serve them an ad on NBCU streaming content accordingly. The brand served custom creatives to consumers based on their food preferences—such as whether they buy meat regularly—with QR codes and calls to action such as, “Light on groceries?” or “Empty fridge?”...

A researcher found that using Anthropic’s Claude Opus 4.7, he could break into the website of Front Gate—used by every festival from Lollapalooza to Bonnaroo—and freely issue any ticket he chose.

If you've submitted a BOM for quoting recently and gotten a lead time that made you do a double take, you're not imagining things. Passive component sourcing in 2026 is tighter than it's been in a few years — and MLCCs are the epicenter. I want to break down why this is happening, which component categories are actually at risk, and — more importantly — what you can do at the design stage to make your board less vulnerable to it. This isn't a "just wait it out" post; there are concrete layout and BOM decisions that meaningfully change your exposure. Why now? Three demand sources are converging on the same MLCC/inductor capacity that used to be dominated by consumer electronics: AI server infrastructure — GPU power delivery networks alone can chew through hundreds of decoupling capacitors per board, and hyperscaler order volumes dwarf typical consumer runs. EVs — automotive-grade passives (AEC-Q200, X8R/X7R) come from a narrower qualified supplier base, so even modest EV growth disproportionately tightens that segment. Renewables/grid infrastructure — pulling on high-voltage inductors and power resistors. On the supply side, new MLCC/ferrite production lines take 12–24 months to come online from the capital decision. Semiconductor fabs can reallocate capacity relatively fast; passive component fabs can't. That structural lag is the real reason lead times stretch out faster than they recover. Which parts are actually at risk Not everything is equally exposed: Category Normal LT 2026 Tight-Market LT Exposure Commercial MLCC (X7R, 0402/0603) 4–8 wks 8–16 wks Moderate–High High-density MLCC (0201, high µF) 6–10 wks 16–26 wks High Automotive MLCC (AEC-Q200, X8R) 10–14 wks 20–30+ wks Very High C0G/NP0 (precision/timing) 4–8 wks 6–12 wks Low–Moderate Power inductors (shielded, low DCR) 6–10 wks 12–20 wks Moderate–High Chip resistors 2–6 wks 4–8 wks Low Chip resistors are the least affected — manufacturing capacity is less concentrated and swapping vendors doesn't trigger a

I'm curious... What's the one feature that instantly makes you stop using a resume builder? For me, it was simple: You spend time creating your resume, everything looks great, and then the site asks you to pay just to download it. That experience inspired me to build Resumship, a resume builder where downloading your resume is completely free. Now I'm thinking about the next features to add, and I'd love to hear from the community. If you were building the ideal resume builder, what features would you include? AI-powered resume suggestions? Better ATS optimization? More templates? Portfolio integration? Cover letter generation? Something completely different? If you have a minute, I'd also love for you to try Resumship and share your honest feedback. 🌐 https://resumship.com Your feedback will directly influence what gets built next. Every suggestion, bug report, or feature request helps make the platform better for everyone. Looking forward to hearing your ideas! 🚀

The Problem When you put RabbitMQ's Management UI behind an nginx reverse proxy under a sub-path like /rabbitmq/ , queue detail pages and many API calls break silently. The root cause: nginx normalizes the request URI before proxying. It decodes %2F (the URL-encoded forward slash) into a literal / . RabbitMQ's Management API uses %2F to represent the default virtual host ( / ) in API paths: GET /api/queues/%2F/my-queue When nginx decodes it: GET /api/queues///my-queue ← broken What Doesn't Work The common advice of using merge_slashes off or a rewrite directive doesn't fully solve this because nginx still normalizes $uri before forwarding. The Fix Use $request_uri inside an if block. Unlike $uri , $request_uri holds the raw, undecoded URI exactly as the client sent it — nginx never touches it. nginx # RabbitMQ: API paths — use $request_uri to preserve %2F (never decoded by nginx) location ~* ^/rabbitmq/api/ { if ($request_uri ~* "^/rabbitmq/(.*)") { proxy_pass http://rabbitmq:15672/$1; } proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; } # RabbitMQ: general UI (JS, CSS, static assets, non-API pages) location ~* ^/rabbitmq/ { rewrite ^/rabbitmq/(.*)$ /$1 break; proxy_pass http://rabbitmq:15672; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; }

Sign-in worked flawlessly in dev. Then a real user pasted a real code and got "invalid format" — before the code ever reached Supabase. The credential was fine. My regex was wrong. Here's the one-line assumption that broke auth for every human who wasn't me. I run a Discord-native Company Brain. Teams /save docs and /ask grounded answers; access is gated by a magic-link claim that emails a one-time code. Standard GoTrue OTP flow. The client shows a box, you paste the code, the server verifies it. Boring — which is exactly what auth should be. The bug: a six-digit assumption in a validation guard The claim handler did a cheap client-side sanity check before calling verifyOtp : // The bug. Looks reasonable. Rejects every real code. const OTP = /^ \d{6} $/ ; function normalize ( input : string ): string { const code = input . trim (); if ( ! OTP . test ( code )) throw new Error ( " Enter the 6-digit code from your email. " ); return code ; } Every OTP tutorial uses \d{6} . Every code demo shows six digits. So I typed six digits into the test and it passed. In dev I was generating my own codes and never actually reading the email. Supabase's GoTrue emits an eight-digit code on this project. ^\d{6}$ rejects eight digits outright. The user's perfectly valid credential got thrown out by my own front door with a lie for an error message — "enter the 6-digit code" when the email plainly showed eight. Why it happens: OTP length is a setting, not a constant The length of a GoTrue email OTP is configurable — GOTRUE_MAILER_OTP_LENGTH (Dashboard → Authentication → Email). It defaults to six in many setups and to eight in others depending on when and how the project was provisioned. The number in the tutorial is that author's project setting , not a property of OTPs. Hardcoding 6 couples your client to a server config you don't control and might change. Bump the length for security later and every client silently starts rejecting valid codes. No error in your logs — the rejection

Quick Answer (TL;DR) Modifying an RDS instance class in place causes 5 to 15 minutes of downtime while AWS reboots the database. To right-size without downtime, use RDS Blue/Green Deployments (fastest, cleanest), a read-replica promotion (works on older engines), or a Multi-AZ failover to a resized standby. Blue/Green is the 2026 default for most workloads on MySQL, MariaDB, Postgres, and now SQL Server. Why this happens RDS instances are Managed EC2 hosts running the DB engine, and a class change (say db.m6i.large to db.m6i.xlarge ) requires stopping the process, migrating the EBS volumes to a new host, and restarting. AWS's default "modify" workflow does this in place and warns you about downtime. The workarounds exist because that reboot is unacceptable for user-facing services, so you build the new instance alongside the old one and cut over. Fix #1: Use RDS Blue/Green Deployments The 2026 default. Available for RDS MySQL, MariaDB, PostgreSQL, and SQL Server (added mid-2025). Steps: In the RDS console, select the instance and choose Actions → Create Blue/Green Deployment . Set the Green instance to your target instance class. AWS creates a full standby using logical replication, keeps it in sync, and validates health. When ready, click Switch over . Cutover typically takes under 60 seconds. Applications reconnect using the same endpoint. Command-line equivalent: aws rds create-blue-green-deployment --blue-green-deployment-name resize-prod --source arn:aws:rds:... --target-db-instance-class db.m6i.xlarge Best when: your engine supports it and you can tolerate the extra cost of running two instances for the sync window. Fix #2: Read-replica promotion For engines or versions that do not yet support Blue/Green, or for cross-region resizing. Steps: Create a read replica with the desired new instance class. Wait for the replica to catch up (near-zero lag). Point application writes to the read replica endpoint (requires connection-string change or DNS switch). Promote

Quick Answer (TL;DR) EC2 Spot lists at up to 90% off On-Demand , but the effective savings after accounting for interruptions, engineering overhead, and workload retries land closer to 40 to 60% for most teams in 2026. Spot wins for stateless, retryable, or checkpointable workloads. It loses money on single-instance stateful services with strict SLAs. The honest formula: True savings = Spot discount × Utilization ÷ (1 + Interruption overhead) . Why the sticker discount is misleading The Spot price is a market price. AWS sets it against unused capacity in a given instance family, region, and Availability Zone, and it can move in minutes. The 90% headline is the maximum discount for a rarely-used instance family in an off-peak region. The workhorses ( m6i , c7i , r7g in us-east-1 ) usually sit at 55 to 75% off. Then there is the hidden cost of interruption. AWS gives a 2-minute warning before reclaiming a Spot instance. Handling that gracefully requires either a stateless workload, a checkpointed job, or careful autoscaler wiring. Teams that do not build for interruption end up with retries, half-finished batches, and engineering time that erases the savings. Fix #1: Diversify across instance types and AZs The single most effective way to reduce Spot interruption rate. Instead of asking for m6i.large specifically, ask for "any of m6i.large , m6a.large , m7i.large , m7a.large in any AZ." AWS pools capacity across the diversification pool. With Karpenter or Auto Scaling Groups: Set the NodePool or ASG's requirements to allow 5 to 15 instance types across families. Include both x86 and ARM (Graviton) options when your workload runs on both. Enable capacity-optimized-prioritized allocation strategy, which picks the deepest capacity pool at launch. Result: interruption rate drops from ~5% per instance-hour to under 1% on most workloads. Fix #2: Use Spot for the right workload shape Not every workload should be on Spot. The rule I use: Great fits : batch processing, data pi
