Originally published on xroot.dev . The rent-cut post explained the economics: Solana is cutting the price of account storage by 90% in five feature-gated steps, and accounts funded at the old price keep every lamport they were funded with. The follow-up question arrived within a day of publishing it: if my account holds more rent than it now needs, can I get the difference back without closing it? For four kinds of account, yes. Here is the arithmetic per type, the instruction that ...

A portable agent definition has a subtle design choice: should it name a model? My thesis is that model: inherit is the better default for an APC agent unless a particular model is genuinely part of the project's contract. It keeps the role portable while letting the runtime make an operational choice. APC is the repository-owned context layer: AGENTS.md and .apc/ describe what a contributor or agent needs to know about a project. APX is the daily-use runtime and tooling layer that read...

Telnet Is Still Open: Why the IoT Botnet Notices Keep Describing the Same Reachable Population When a national CERT publishes a notice about active botnet families, the intrusion methods listed are usually unremarkable. The August 2026 notice from China's National Network and Information Security Notification Centre named five cross-border families — Mirai, CondiBot, Gafgyt, TBot and SoftBot — and described initial access through Telnet and SSH brute force against unchanged factory credentia...

When an application accepts customer information, the database is usually treated as the final destination. But by the time data reaches the database, it may already be too late to fix problems efficiently. This is especially true for address data. A customer might enter an incomplete street name, an incorrect ZIP Code, or an outdated address. If the application stores that information without checking it, the bad record can move into billing systems, customer databases, fulfillment workflows...
