Dev Sk — Mon, 12 Oct 2026 09:30:00 +0000

Jake Goldsborough’s latest blog is a refreshing reminder that not every “hard part” in software development is worth obsessing over. Sometimes, the industry gets caught up in complexity that doesn’t actually move the needle for users or teams.

🔑 Key Insights
Focus on impact → The hardest problems aren’t always the most important ones.

Simplification wins → Cutting through noise helps teams deliver faster and smarter.

User-first mindset → What matters is solving problems that create real value.

Letting go → Saying goodbye to unnecessary complexity is a sign of maturity, not weakness.

💡 Takeaway: Engineering isn’t about proving how tough a problem is — it’s about solving the right problems that matter.

🤝 Human-AI Partnerships: It’s About Alignment, Not Just Capability

Dev Sk — Wed, 30 Sep 2026 09:30:00 +0000

Sean Goedecke’s latest blog challenges a common assumption: AI partnerships aren’t only about boosting raw capability — they’re about ensuring alignment with human goals, values, and context.

🔑 Key Insights
Capability ≠ alignment → AI can be powerful, but without alignment, it risks going off-track.

Partnership mindset → Humans provide direction, context, and judgment; AI provides scale and speed.

Trust & responsibility → True collaboration means designing systems that reflect human intent.

Future of AI → Success will depend less on “how smart” AI is, and more on how well it aligns with us.

💡 Takeaway: The real challenge isn’t building more capable AI — it’s building AI that works with us, not just for us.

⚠️ When AI Goes Down, What’s Your Backup Plan?

Dev Sk — Tue, 15 Sep 2026 09:30:00 +0000

Recently, ChatGPT, Claude, and Grok all went offline at the same time — a stark reminder that even the most advanced AI systems aren’t immune to outages. For enterprises increasingly dependent on AI, this raises a critical question: What happens when your AI tools fail?

🔑 Key Insights
Single point of failure → Relying on one AI provider can leave businesses vulnerable.

Resilience matters → Enterprises need redundancy, fallback systems, and clear continuity strategies.

Human-in-the-loop → AI is powerful, but human oversight ensures operations don’t grind to a halt.

Strategic planning → Treat AI like any other critical infrastructure — plan for downtime before it happens.

💡 Takeaway: AI outages aren’t just technical hiccups — they’re business risks. Building resilience into your AI strategy is no longer optional, it’s essential.

🧠 Agentic Skill Decay — A New Challenge in the AI Era

Dev Sk — Sat, 12 Sep 2026 09:30:00 +0000

Addy Osmani explores a fascinating idea: as AI agents take on more tasks, humans risk losing the very skills that make us effective problem-solvers.

🔑 Key Insights
Automation trade-offs → Delegating too much to AI can erode human expertise.

Skill decay → Over-reliance on agents may weaken critical thinking and technical depth.

Balance is key → The future isn’t about replacing humans, but about designing workflows where AI augments rather than diminishes our abilities.

Long-term impact → How we integrate AI today will shape the skills we retain tomorrow.

💡 Takeaway: The rise of agentic AI isn’t just about efficiency — it’s about responsibility. We must ask: Are we building systems that strengthen human capability, or ones that let it fade?

📌 SQL Server Table Types: Passing Tables as Parameters

Dev Sk — Thu, 10 Sep 2026 09:30:00 +0000

One of the most underrated features in SQL Server is the user‑defined table type. Instead of passing CSV strings or looping through rows, you can send an entire set of structured data into a stored procedure.

🔍 What They Are
A table type defines a schema (columns, constraints) for a table variable.

Procedures/functions can accept this type as a parameter (READONLY).

Internally, SQL Server materializes it as a table variable in tempdb during execution.

⚙️ How They Work Internally
When you pass a table type parameter, SQL Server creates a table variable instance based on the type definition.

Data is stored in 8 KB pages like any other table.

Small sets → kept in memory; large sets → spilled into tempdb.

Optimizer treats it like a table variable, but with limited statistics (often assumes 1 row).

Constraints (like primary keys/unique) act as indexes, but you can’t add non‑clustered indexes dynamically.

⚡ Why They’re Useful
Batch operations: Insert/update multiple rows in one call.

Strong typing: Procedure knows exactly what columns to expect.

Reusable: Define once, use across multiple procedures.

⚖️ Trade‑offs
Always READONLY → you can’t modify the parameter inside the procedure.

No full statistics → optimizer may misestimate row counts for large sets.

Limited indexing → only PK/Unique constraints allowed.

Performance → great for small/medium sets; for very large sets, temp tables often perform better.

🚀 SQL Server Performance Quirk I Ran Into

Dev Sk — Tue, 08 Sep 2026 09:30:00 +0000

🚀 SQL Server Performance Quirk I Ran Into

Recently, I noticed something odd in one of my stored procedures:

First run after SQL Server restart → 33 seconds ⏳

Subsequent runs → ~230 ms ⚡

At first glance, it looked like my indexing wasn’t working. But digging deeper, I realized this was a cold cache vs. warm cache issue:

On the first run, SQL Server has to compile the execution plan, load data pages from disk, and initialize tempdb structures.

On later runs, the plan cache and buffer pool are already primed, so queries fly.

✅ The Solution
Pre‑warm cache: Run critical procedures once after restart (via SQL Agent job) so the plan and data are ready before real users hit them.

Keep statistics fresh: Enable auto‑update (and async) or schedule jobs to refresh statistics. This ensures the optimizer has an accurate “map” of the data and picks efficient plans.

⚖️ Trade‑offs
Pre‑warming consumes memory up front, so only do it for high‑impact procedures.

Updating statistics too often can be I/O heavy, but too rarely leads to poor query plans. Balance is key.

💡 Takeaway: Sometimes performance issues aren’t about “bad queries” — they’re about how SQL Server warms up and how well its optimizer understands your data.

🚀 SQL Server TempDB: Tradeoffs & Optimizations You Shouldn’t Ignore

Dev Sk — Sun, 06 Sep 2026 05:30:00 +0000

TempDB is the workbench of SQL Server — every query, sort, join, and temporary object touches it. Misconfiguring tempdb can slow down your entire server.

⚖️ Tradeoffs (Think: Shared, Temporary, Busy)
Shared by all sessions → everyone uses it.

Temporary → cleared at every restart.

Busy → heavy workloads can overload it.

No recovery → always in simple mode.

Performance risk → misconfiguration = bottlenecks.

🔧 Optimizations (Think: 8 Equal Fast Monitored)
8 files max → one per CPU core, up to 8.

Equal size & growth → balance usage.

Fixed growth → MB increments, not %.

Pre-size → avoid autogrowth storms.

Fast storage → SSD/NVMe preferred.

Monitor → watch PAGELATCH waits.

Tune queries → reduce spills & temp tables.
