Revisiting Bloom Filter Efficiency in LSM Trees - thoughts from some recent readings .. Almost all LSM based storage structures use bloom filters in front of their memtable structures to reduce IO overhead at least for the target keys not present in the underlying secondary

LSM trees power some of the most popular databases like Cassandra, RocksDB, LevelDB, etc; but they suffer from a massive problem ⚡ Although they are a popular choice for write-heavy use cases, they see latency spikes under a heavy workload. This typically happens because

Columnar file formats like Parquet/ORC are ubiquitous. Our VLDB paper with Xinyu Zeng + Huanchen Zhang + Wes McKinney studies their internals. TLDR: They're not optimized for modern hardware. Something new is needed. Paper: vldb.org/pvldb/vol17/p1… Code: github.com/XinyuZeng/Eval…

SIMD intrinsics is the way. Every single AVX algo we wrote for KnoxDB is hand crafted for maximum performance. A compiler could not have done that.

Best take on AI I’ve seen so far. Ironically many people’s, often well paid, jobs are copy paste to some extent.

New Remote Code Execution vulnerability in OpenSSH. Fixed in version 9.8 released today. Update your servers.

We have done it! For the first time ever a ZK-proof has been verified on Bitcoin Mainnet by BitcoinOS. The final verification was confirmed in block 853626. A historic moment and a historic block. A new era has begun for Bitcoin enabling unlimited scaling and functionality -

Thank God. Men can’t get pregnant anymore.

*Commodity* hardware outpacing what's available in the cloud is an interesting trend that seems to support betting on maybe-not-just-cloud databasearchitects.blogspot.com/2024/02/ssds-h… transactional.blog/blog/2024-mode…

From 20 people on a Lisbon rooftop to 1000+ global leaders across Ethereum, Bitcoin, Solana & more. Lisbon → Istanbul → Bangkok → Dubai 🇦🇪

Ethereum is the last bastion of cypherpunk / 3,3 values because a lot of people & institutions in Ethereum got rich at a time when it was easier to do that while being idealistic. That is why I say 'ETH goes hard'--it will be the only ecosystem that truly cares about

The bullshit bingo never ends …

I heard someone today say “we shouldn’t pretend Tornado Cash isn’t used for illicit purposes”. I don’t pretend Tornado Cash is used for one thing or another - it’s none of my business what people use software for.  It’s also not anyone else’s business what anyone does with their

Over the years, I’ve worked with many students, some now thriving in the software industry. The trait that sets the successful ones apart? Leadership. My best research assistants took initiative, helping without being prompted. Most, however, waited for me to organize their

LAW: no crash-tolerant [linearizable + async + local] reads can ever exist. Cheat: almost-local [safe, cheap, high xput] reads! More in law-theorem.com & our #VLDB’25 paper

This is what sustainable innovation and true DeFi means. Every new protocol feature benefits the token holders, the local ecosystem and the global on-chain economy.

No 1 rule for long-term investing in DeFi governance tokens: Look for how much of the value captured by a protocol is directly funneled back to token holders. - zero = unsustainable or scam (TAO) - 50% = gold standard (CRV) - more = too extractive, suspicious (SNX, VELO)

Happy New Year everyone! 2026 will be awesome.
