LLM quantization techniques I'd learn if I had to fit a 70B model on a single GPU: (bookmark this) A 70B model in FP16 needs 140GB for weights alone. At 4-bit, that drops to 35GB, which fits on one card. But naive rounding fails on large models. Roughly 0.1% of hidden dimensions carry values up to 20x larger than anything else in the tensor, and they wreck the quantization grid for everything else. Each of these 5 methods handles those outliers at a different point: 1. RTN: ignores them. Rounds every weight to the nearest grid level with no calibration data. Cheapest option, weakest at low bit widths. 2. GPTQ: repairs after rounding. Quantizes a layer column by column and adjusts the remaining weights to absorb the error before moving on. 3. AWQ: protects before rounding. Finds the ~1% of weight channels that matter most and scales them up so they survive quantization. Everything still ends up in plain INT4. 4. LLM. int8(): isolates at inference. Outlier dimensions run in FP16, the other 99.9% run in INT8, and the results are merged. 5. QAT: solves it during training. The model is fine-tuned with rounding baked into every forward pass, so it adapts to the damage before quantization is actually applied. All five produce the same artifact, a model at a fraction of its trained precision. They differ only in where the outlier problem gets addressed. The visual below nicely summarise these techniques. There's a really good paper that provides a comprehensive study of LLM quantization techniques: arxiv.org/abs/2411.02530 --- That said, quantization shrinks a model, but fine-tuning is how it gets adapted to a specific use case in the first place. I wrote a full breakdown on fine-tuning LLMs with RL in 2026, including how to skip manual reward engineering with automatic LLM-graded rewards. The article is quoted below!

𝗜'𝘃𝗲 𝗯𝘂𝗶𝗹𝘁 .𝗡𝗘𝗧 𝗔𝗣𝗜𝘀 𝘁𝗵𝗮𝘁 𝗵𝗮𝗻𝗱𝗹𝗲 𝗺𝗶𝗹𝗹𝗶𝗼𝗻𝘀 𝗼𝗳 𝘁𝗿𝗮𝗻𝘀𝗮𝗰𝘁𝗶𝗼𝗻𝘀 𝗮 𝘆𝗲𝗮𝗿. You don't need Kubernetes or microservices to reach 1 million users. The secret? Scale up before you scale out. Add complexity only when it actually hurts. Most apps break because of bad architecture decisions, not high traffic. Here is the real path from day one to 1M users: 📌 𝟭. 𝗣𝗿𝗲𝗹𝗮𝘂𝗻𝗰𝗵 (𝗠𝗩𝗣) → Monolith + 1 relational database → Single VPS with Docker Compose → TLS, backups, and logging from day one 📌 𝟮. 𝗛𝘂𝗻𝗱𝗿𝗲𝗱𝘀 𝗼𝗳 𝘂𝘀𝗲𝗿𝘀 → App + DB in Docker on one box → Add a CDN for static files → Scale up, stay simple 📌 𝟯. 𝗧𝗵𝗼𝘂𝘀𝗮𝗻𝗱𝘀 → Move the DB out of Docker, run it as native service → Add connection pooling and an in-memory cache → Fix N+1 queries and add indexes before buying hardware → Push slow work into background jobs 📌 𝟰. 𝟭𝟬𝗞 𝘂𝘀𝗲𝗿𝘀 → Give the DB its own server → Now the app and DB stop fighting for resources → Optimize queries first, buy hardware second → 2+ app instances behind a load balancer 📌 𝟱. 𝟱𝟬𝗞 𝘂𝘀𝗲𝗿𝘀 → Go cloud: managed compute + managed DB → Add a message broker (RabbitMQ, Kafka) for write spikes → Move some modules to Microservices or Serverless Functions → Move sessions and cache to Redis → Add read replicas only if reads are the real bottleneck 📌 𝟲. 𝟭𝟬𝟬𝗞+ 𝘂𝘀𝗲𝗿𝘀 → Layered caching with a clear invalidation strategy → Partition and archive old data → CQRS read models for heavy read screens → Use NoSQL database for heavy write scenarios 📌 𝟳. 𝟭𝗠+ 𝘂𝘀𝗲𝗿𝘀 → Shard the database (split by function first) → Kubernetes + microservices along team boundaries → Add tracing, SLOs, load and chaos testing Notice that your database path never changes: Docker → native service → own server → cloud → replicas → shards That single line is the whole game. Follow it in order and skip nothing. Your database is almost always the first thing to fall over, so give it room to grow before you touch anything else. Most apps never get past step 4. And that is completely fine. The people who ship microservices on day one usually do it for their resume, not for their users. Remember these rules: → Measure load, not user count → Scale up before you scale out → Fix your code before your infrastructure → Split for teams, not for traffic → Every new component adds a new failure mode and a new cost ✅ Keep the monolith as long as you can. ❌ Don't design your MVP like it's already at 1M users. —— ♻️ Repost to help others scale without over-engineering ➕ Follow me ( @AntonMartyniuk ) to improve your .NET and Architecture Skills

A lot of people know ping for testing Layer 3 connectivity, but arping is incredibly useful when troubleshooting Layer 2. While setting up my lab, my PC and Proxmox server were connected to a Hillstone zone-based firewall using a VSwitch. Both interfaces were in the same l2-trust zone, on the same subnet, with no VLAN separation. Both devices could ping the default gateway, but they could not ping each other. I checked the ARP tables using: $ arp -an $ ip neigh Both devices had learned each other’s MAC addresses. I then tested direct Layer 2 reachability with arping. arping worked, proving that ARP resolution and Layer 2 forwarding were functioning correctly. That narrowed the issue down to IP traffic. The firewall was allowing ARP so the devices could resolve each other’s MAC addresses, but it was blocking IPv4 traffic between devices in the same Layer 2 security zone. The fix was to create an explicit policy allowing: l2-trust → l2-trust

Copilot Chat is a place to draft, summarize, analyze, and explore ideas Example: 'Summarize this meeting recap and turn it into 5 client-ready next steps' ▶️ Cowork = execute for me Use it when the task is multi-step, long-running, and needs action across Microsoft 365. Cowork is now generally available worldwide for Microsoft 365 Copilot customers Example: 'Create a prep pack for next week's business review using the latest deck, notes, emails, and spreadsheet' ▶️ Scout = stay ahead for me (requires Copilot 365 + GitHub Copilot) Use it when the goal is proactive coordination: surfacing risks, preparing for meetings, monitoring priorities, or handling routine tasks. Scout is currently part of Frontier Example: 'Flag schedule conflicts, prep me for key meetings, and monitor follow-ups I may miss' Simple rule: Copilot App helps me think Cowork helps me move work forward Scout helps me stay ahead - Follow @heyitsurya For Daily useful Twitte

Running AI agents means managing more than model calls. Coral Server is the Kotlin server behind CoralOS for teams building and operating AI-agent systems. It helps you manage the path from agents to deployment by combining a registry, runtimes, authentication, and orchestration in one configurable service. Key features: • Agent registry – organizes the agents available to your system • Docker runtime – runs agents in containers from the published server image • Key-based authentication – loads required auth keys from TOML or command-line arguments • Flexible configuration – maps nested properties, collections, and simple data types to CLI options • Two launch paths – run it with Gradle or use the image published on GitHub Container Registry The README and connected docs are marked as works in progress. The minimal Docker image also requires access to the host Docker socket and supports Docker-based agents only. Free public GitHub repo. Link in the reply 👇

Virtual nodes let one physical server own many small, separated ranges instead of one large range. Rather than placing s0 once on the ring, place several derived identities such as s0_0, s0_1, and s0_2. Each virtual node still uses the same clockwise lookup rule. - Once found, it resolves back to its physical server. Now each server owns multiple partitions distributed around the ring. - A large gap at one of its positions is less likely to determine its entire share of the keyspace. Virtual nodes change the topology, not the ownership rule. The lookup remains "first clockwise node" - there are simply more positions representing each machine.

Agent Tool Result Validation and Quality Gates Agents often trust tool outputs without checking them. Adding validation and quality gates after tool execution helps catch errors, incomplete results, or unexpected data before the agent continues. This is becoming essential for reliable agent workflows. As a dev, I now implement post-tool validation in production agents. Tool Result Validation Cheatsheet: Define expected structure and quality rules for tool outputs Validate results before using them in further reasoning Handle validation failures with clear fallback logic Log validation failures for monitoring Combine schema checks with semantic validation when needed Pro tip: Validating tool results early prevents many downstream agent failures How are you validating tool outputs in your agents?

7 database mistakes that silently kill prod performance: 1. No indexes on foreign keys Full table scans on every join. Your app slows down gradually. You never notice why. 2. SELECT * everywhere Pulling 50 columns when you need 3. Wasteful at scale. 3. N+1 queries 1 query per item in a loop. 1000 items = 1000 queries. App dies under load. 4. No connection pooling Opening new DB connections per request. Destroys performance under traffic. 5. Migrations without a plan in prod Table locks at peak traffic. Have fun explaining that outage. 6. No slow query log Flying completely blind on what's actually slow. 7. Storing blobs in the DB Use S3. Store the URL. Your DB is not a file system. Most app slowdowns are database slowdowns in disguise.
