What you need before you have a problem worth solving A few weeks ago, I caught up with my good friend Lucas Mara, a thoughtful design leader. We were deep in a conversation about the value of...

When LinkedIn engineers encountered short-lived, recurring outages where the database powering their user feed became unavailable and then recovered without leaving helpful traces, they had to...

eBPF is emerging as a preferred method for security observability over traditional user-space agents. By attaching probes directly to the Linux kernel's syscall interface, it provides consistent...

In this podcast, Jaromir Hamala, a seasoned Java engineer specialising in high-throughput data systems, shares his thoughts on how developers can tackle high-performance software development. He...

Linux Kernel 7.1 合并了全新原生 NTFS 驱动程序，显著提升了对 NTFS 文件系统的支持。该驱动程序由开发者 JEON 重写，性能提升明显，单线程写入提高 3%~5%，多线程写入提高 35%~110%。新驱动程序支持完整的读写操作，降低 CPU 开销，改善跨平台文件共享效率。正式版预计在 2026 年发布。

Anthropic researcher Nicholas Carlini used Claude Code to find a remotely exploitable heap buffer overflow in the Linux kernel's NFS driver, undiscovered for 23 years. Five kernel vulnerabilities...

Linux Kernel 7.0 正式版发布，主要更新集中在稳定性、安全性和驱动兼容性，修复了数百个补丁，涉及网络、内存管理、安全加密和硬件支持等方面。用户可下载源码编译，待各大发行版适配后可升级。Linus Torvalds 已开启 7.1 合并窗口，开发将更加活跃。

Intel 486 处理器将逐步退出历史舞台，Linux Kernel 从 7.1 版起移除对 i486 架构的支持。该架构自1989年发布，2007年停产，用户已极少，内核团队认为继续支持已无必要，未来 LTS 版也将停止支持 i486。

It is 3 AM. A rogue DELETE just wiped 500,000 customer records. Traditional recovery takes hours and risks collateral damage. This guide shows you how to recover accidental DELETEs and UPDATEs in...

In PostgreSQL, a DELETE operation does not immediately erase data from disk. The MVCC mechanism retains deleted rows as dead tuples, and reading these dead tuples is one viable approach to data...

Linux Kernel 6.19 正式发布，包含安全架构、网络协议和文件系统等多项改进，标志着 6.x 系列的结束，并开启 7.0 合并窗口。新增多处理器支持、ext4 巨型块和图形驱动 HDR 输出等功能，增强硬件支持。

飞桨框架3.0推出了多硬件统一适配方案，降低了硬件适配成本，支持即插即用接入。该方案通过插件架构和标准接口，简化接入流程，提升模型训练和推理性能，降低开发门槛，促进硬件生态落地。

当多个插件同时使用时，Semantic Kernel 通过函数调用实现任务规划，支持并行调用，简化复杂任务处理。旧规划器已被弃用，建议使用函数调用以提升开发体验。

本文介绍了Semantic Kernel的核心组件Kernel和Plugins在.NET开发中的应用。Kernel作为调度器，管理AI模型和资源，支持异步和多模型。Plugins封装可复用功能，分为本土和语义插件，便于集成外部工具。通过示例展示了天气查询插件的构建，强调了扩展性和灵活性，促进AI与传统开发的结合。
