@muratdemirbas and I did a fun exercise and read a HotOS paper ("Real Life Is Uncertain. Consensus Should Be Too!") together. We recorded the entire messy process. It is a long video of us reading, questioning, guessing, and arguing with the paper. youtu.be/4HTc4o-t3Cw

Deep work crushes shallow signals. Amidst this deepseek frenzy, ask yourself - when did you last think deeply or do something intellectually challenging? If not, you’re just over-optimizing your career while others innovate. Take bets. Take on tougher problems. Challenge yourself with harder subjects. When was the last time you learnt something just for fun and not because it will give you a "better job"? Until this happens, someone else will keep creating deep-tech, while we crib! note - this is for those who are now making decent income and out or scarcity.

Organising the first meet-up of the year! Come folks see you there 🦀

First post of the year! @andy_pavlo got me thinking about why Confluent didn't build WarpStream. My conclusion: legacy infrastructure companies are going to have a tough time against cloud native, AI-enabled, post-ZIRP competitors. materializedview.io/p/infras…

As another update, considering to finally relocate to Bangalore this January, have a lot of things to figure out there though (renting a place, etc).

Hoping to be more active here (and other platforms) this year. I spent most of 2024 working on my relationships (2023 was a roller coaster in that regard) and focusing exclusively on job (finally the product that I was working on got GA’ed in December 🥳).

This week on the unikernel application spotlight we boot up @TigerBeetleDB a new fast OLTP db! Written in @ziglang it makes use of io_uring via @axboe , O_DIRECT, a deterministic simulator and way more than I can put into this tweet - check it out. youtube.com/watch?v=OjhBNsTf…

Voltron layoffs, super unfortunate. You should hire Felipe.

New post is up! Next-gen infrastructure must support flexible deployments. Embedded, single-node, clustered, BYOC, SaaS, and self-managed. We're finally able to do this with one codebase. materializedview.io/p/the-ne…

week 34, streaming kernel dev topic: debugging wild low level boot issues (pre-recorded since I'm on vacation, recap vid in thread) youtu.be/-hKU2UZ6Tvw

Seokjoo Cho (@seokjoo_cho) presents his work on building ScaleCache, a scalable page cache for multiple SSDs at @IllinoisCDS Systems Research Seminar. The work appears at EuroSys'24, dl.acm.org/doi/abs/10.1145/3… @seokjoo_cho is a 1st-year PhD student advised by @AishwaryaGanlat and Ram Alagappan.

matklad will present TigerBeetle’s LSM-Forest compaction at @P99CONF - storage determinism across replicas for faster recovery from disk faults - perfect pacing to solve write stalls for predictable P100s - and with static memory allocation p99conf.io/agenda/#thursday

TigerBeetle’s LSM compaction is “the beating heart” of the database. Bringing together ideas at the intersection of global consensus protocol and local storage engine.

We just released slatedb.io 0.2.0! 🎉 This release has: - in-memory block cache - on-disk object cache - garbage collection - compressed bloom filters Next up: admin CLI, range queries, and more cache improevements.

You can run `docker buildx debug build` and get interactive shell on build failure

Came across this book today. While the CSAPP book has a couple of chapters on these topics, this book is completely devoted to just memory hierarchy and tries to provide a holistic overview of the system, including cache memory, RAM and spinning disks. It's a bit dated now and does not discuss SSD or NVME storage. The ToC is very interesting and includes case studies from real-world systems. Now, only if there was enough time to read it.

I wrote a post on how data serialization and unproductive allocations can negatively impact your application. In it, I show how very simple tools and minor code changes can lead to great performance improvements. Read it here: blog.vbang.dk/2024/09/10/seb…

Many of you know I've been angel investing for a while now. Today I'm excited to announce the next step: I've started Materialized View Capital. MVC is a micro VC fund that lets me continue doing what I enjoy, and take some friends along for the ride. materializedview.capital

New post! I talk with @philippemnoel about @paradedb, the experience of building as a PostgreSQL extension, pg_duckdb, pg_lakehouse, and more... materializedview.io/p/search…
