https://taoofmac.com/media/reviews/2026/04/11/1900/gXPeL88wnWdIRTzHXp4uBm8vFnU=/hero.jpg
The Orange Pi 6 Plus, a board with a CIX P1 SoC, showed promising hardware but struggled with software issues, requiring custom OS images and vendor-specific GPU and NPU userspace. Despite these challenges, the board proved usable for local AI work, with some models and runtimes performing well, but its high power draw and loud fan made it less attractive as a low-traffic always-on appliance.

5NF and Database Design

https://kb.databasedesignbook.com/posts/5nf/wikipedia-1.png
The traditional way of teaching fifth normal form (5NF) is confusing and unnecessary, and a more logical approach is to start with business requirements and create a physical table schema using a textbook table design strategy. Two patterns of physical table design follow naturally: the AB-BC-AC triangle and the ABC+D star pattern, both of which are fully normalized and do not require 5NF ...

Understanding Clojure's Persistent Vectors, pt. 1 (2013)

https://hypirion.com/sha/a90ab1743d3840abf7251f797e8cc0d0a05e42bdab57c0dfa91d3eac4adcd0e3.png
Clojure's persistent vectors use balanced, ordered trees to achieve O(1) runtime for appends, updates, lookups, and subvec operations while maintaining persistence. The tree structure is shallow due to a high branching factor, allowing for "effectively" constant time modifications and lookups, although technically O(log32 n).

Troubleshooting Email Delivery to Microsoft Users

Microsoft temporarily blocked our emails to Hotmail, Live, MSN, and Outlook users due to a rate limit, but it was later resolved after we implemented a Redis-backed throttler to control our sending rate. The issue was likely caused by a spike in email traffic from our IPs, which Microsoft's algorithms flagged as suspicious, and we are considering warming up an IP solely for transactional ...
