Since the advent of ChatGPT, and later by using LLMs that operate locally, I have made extensive use of this new technology. The goal is to accelerate my ability to write code, but that’s not the only purpose. There’s also the intent to not waste mental energy on aspects of programming that are not worth the effort.
[...] Current LLMs will not take us beyond the paths of knowledge, but if we want to tackle a topic we do not know well, they can often lift us from our absolute ignorance to the point where we know enough to move forward on our own.

lmdb.tcl —the first version of Redis, written in TCL (via) Really neat piece of computing history here—the very first version of what later became Redis, written as a 319 line TCL stript for LLOOGG, Salvatore Sanfilippo’s old analytics startup. # 18th May 2023, 4:57 pm
After three decades of working with software, I’m also seeing myself learning faster using ChatGPT. So apparently it works even for us more seasoned programmers.

For Redis 4.2 I’m moving Disque as a Redis module. To do this, Redis modules are getting a fully featured Cluster API. This means that it will be possible, for instance, to write a Redis module that orchestrates N Redis masters, using Raft or any other consensus algorithm, as a single distributed system. This will allow to also model strong guarantees easily.

Streams: a new general purpose data structure in Redis. Exciting new Redis feature inspired by Kafka: redis streams, which allow you to construct an efficient, in-memory list of messages (similar to a Kafka log) which clients can read sections of or block against and await real-time delivery of new messages. As expected from Salvatore the API design is clean, obvious and covers a wide range of exciting use-cases. Planned for release with Redis 4 by the end of the year! # 3rd October 2017, 3:25 pm

VMware: the new Redis home. Redis creator Salvatore Sanfilippo is joining VMWare to work on Redis full time. Sounds like a good match. # 16th March 2010, 11:26 am
Redis Virtual Memory: the story and the code. Fascinating overview of the virtual memory feature coming to Redis 2.0, which will remove the requirement that all Redis data fit in RAM. Keys still stay in RAM, but rarely accessed values will be swapped to disk. 16 GB of RAM will be enough to hold 100 million keys, each with a value as large as you like. # 9th February 2010, 3:59 pm

New Redis ZINCRBY command (via) Just added to Redis, a command which increments the “score” for an item in a sorted set and reorders the set to reflect the new scores. Looks ideally suited to real time stats, and I’m sure there are plenty of other exciting uses for it. # 22nd December 2009, 8:38 pm
I think that what’s particularly hard with C is not the details about pointers, automatic memory management, and so forth, but the fact that C is at the same time so low level and so flexible. So basically if you want to create a large project in C you have to build a number of intermediate layers (otherwise the code will be a complete mess full of bugs and 10 times bigger than required). This continue design exercise of creating additional layers is the hard part about C. You have to get very good at understanding when to write a function or not, when to create a layer of abstraction, and when it’s worth to generalize or when it is an overkill.

redis (via) An in-memory scalable key/value store but with an important difference: this one lets you perform list and set operations against keys, opening up a whole new set of possibilities for application development. It’s very young but already supports persistence to disk and master-slave replication. # 15th March 2009, 1:32 pm
