Single log line is 49KB+ (ext4) / 110KB+ (btrfs) of systemd-journald disk writes
• systemd-journald version 257.9 on Debian 13 with Linux kernel 6.12.57+deb13-amd64 causes excessive IO.
• VM running journald writing 2 log lines/second does ~50 IOPS, much higher than syslog.
• File system used is XFS, and journald writes logs directly to hard drive causing slowdown.
• Issue reproduces with constant logging stream from haproxy showing frequent disk write spikes.
• Problem linked to journald inefficiency and inflated log file sizes, also prone to corruption on unclean reboots.#systemd #journald #IOPS

NP-Overrated
• NP-hard problems are theoretically intractable but often practically solvable on most inputs.
• Dependency resolution and type checking rarely encounter worst-case complexity in real scenarios.
• Advanced optimization tools can find provably optimal solutions for scheduling and traveling salesman problems efficiently.
• Algorithmic improvements outpaced hardware gains, achieving up to 450-billion-fold speedup (1991-2015).
• Even SAT and SMT problems are routinely solved at scale, e.g., Amazon handles a billion SMT queries daily.#NPcomplete #Algorithms #Optimization

How Compaction Works in Pi
• Pi triggers compaction when conversation exceeds LLM context window, preventing errors.
• Compaction summarizes older conversation parts using an LLM, preserving recent messages.
• Pi's compaction prompt requests structured summaries focusing on goals, progress, and decisions.
• Compaction appends a plain text summary to the session, retaining readable and portable context.
• Compaction breaks prompt caching due to changed context prefix but allows continued use afterwards.#PiLLM #AICompaction #CodingAgents

Why does Opus 5 feel worse to work with?
• Opus 5 is more capable than Opus 4.7, 4.8, and rivals Fable in benchmarks.
• Opus 5 requires more 'babysitting' as it makes assumptions without asking for clarification.
• Earlier models pause to ask questions and avoid reinterpreting plans without checking.
• Benchmark-driven model training favors bold assumptions to maximize scores.
• Users prefer agents that ask for clarification due to real-life ambiguity and consequences.#Opus5 #AIbenchmarks #CodingAgents

Blog about things you don't understand yet
• Each blog post represents at least two things learned: the initial topic and insights during writing.
• Posts always argue a point; drafts without controversy are scrapped to encourage research and deep thinking.
• Writing clarifies understanding and often changes the author's mind on the topic.
• Beginner writers can create valuable introducations and challenge public misconceptions effectively.
• Feedback, including from LLMs, is crucial despite potential harsh criticism, enhancing the learning process.#BloggingTips #LearningByWriting #CriticalThinking

Don't classify, hallucinate!
• LLMs struggle with constrained classification due to large legal vocabularies for product categories.
• Classic method uses structured outputs with extensive literal schema for legal classification values.
• New approach: have LLM hallucinate plausible fake classifications instead of using real taxonomy.
• Embed real and fake classifications using MiniLM, then find closest real category via vector similarity.
• This method reduces API token cost and schema shipping, enabling use of smaller, cheaper LLMs.#LLMClassification #VectorSearch #EcommerceAI
