Motivation Around 20% of Firefox’s HTTP traffic today uses HTTP/3, which runs over QUIC, which in turn runs over UDP. This translates to substantial UDP I/O activity. Firefox uses NSPR for most of its network I/O. When it comes to UDP I/O, NSPR only offers a limited set of dated APIs, most relevant here PR_SendTo and PR_RecvFrom, wrappers around POSIX’s sendto and recvfrom. The N in NSPR stands for Netscape, giving you a hint of its age.

埃文斯顿市政府要求私人监控供应商Flock Safety重新拆除其未经许可擅自重新安装的固定车牌识别摄像头。
此前,由于发现Flock公司违反伊利诺伊州法律,允许美国海关和边境保护局访问该州摄像头数据,并被报道其他州执法机构利用其数据协助移民案件,埃文斯顿市已于8月26日下令关闭19台Flock摄像头(18台固定,1台车载),并启动为期30天的合同终止程序。截至9月8日,Flock已移除其中15台固定摄像头。
然而,至9月23日(周二),这15台摄像头已被全部重新安装回原位置或附近。市政府发言人证实,城市政策未变,Flock的重装行为未经授权,并已发出停止和终止令。Flock随后承诺将迅速移除摄像头。
现场调查显示,重装的摄像头大多绑回原有街灯柱上,部分安装在新建的独立电线杆上。值得注意的是,部分摄像头型号发生变化,由原先的“Falcon”型号更换为外观更短小、类似“Standard”的型号,且部分型号缺少太阳能板,可能改为接入城市电网供电。
更关键的是,尽管市政府声称摄像头自8月26日起已停止运行,但Flock公司自己的“透明门户网站”数据却显示异常。该网站显示的摄像头数量在关闭后并未降至零,且“过去30天检测车辆数”的下降速度远低于预期。数据分析表明,在8月26日关闭命令后,可能仍有部分摄像头处于活动状态并记录车辆数据,与城市官员的声明及Flock的通信内容相矛盾。
目前,埃文斯顿市已支付Flock五年合同的前两年费用,若合同继续有效,还需支付剩余三年的145,500美元。市政府计划于9月26日正式终止合同,但Flock公司对此提出异议,双方争端可能升级为法律诉讼。
There are books & many articles online, like this one arguing for using Postgres for everything. I thought I’d take a look at one use case - using Postgres instead of Redis for caching. I work with APIs quite a bit, so I’d build a super simple HTTP server that responds with data from that cache. I’d start from Redis as this is something I frequently encounter at work, switch it out to Postgres using unlogged tables and see if there’s a difference.

自1964年棋局组合大师内纳德·佩特罗维奇发表了一个具有218步可行走法的国际象棋局面以来,人们一直在尝试打破这个记录。本文作者Tobs40于2024年5月通过计算机科学和数学方法,旨在从根本上解决这一问题,并最终证明218是可达位置中轮到走棋的一方所拥有的合法走法的绝对最大值。
证明的关键难点在于,国际象棋的可达合法局面总数约为4.8×10^44个,进行暴力穷举是完全不可行的。因此,必须采用数学证明和优化算法来设定一个严格的上限。
作者将问题建模为一个优化问题,目标是在所有可能的棋盘配置中最大化可行走法的数量。为了处理海量的可能性,使用了以下关键技术:
经过计算优化,求解器最终证明,即使允许分数棋子和分数走法,可行走法的最大值也无法超过218。由此可以断定,在所有从初始位置合法可达的局面中,轮到走棋的一方最多有218种走法可选。
研究还得到了其他相关结果:
作者提出,类似的数学优化方法未来可应用于解决其他国际象棋组合极限问题,例如:

现状分析
尽管前沿模型在编程竞赛中已展现超人智能(如OpenAI的GPT-5在ICPC竞赛中满分夺冠),但编程智能体在实际软件开发中仍无法替代开发者。根本限制因素已从智能不足转向上下文缺失。
智能体自主性层级
作者将智能体自主能力分为五个层级:
核心瓶颈:上下文而非智能
编程竞赛中所有解题信息均包含在问题描述中,而实际开发需要智能体理解远超代码本身的信息。随着模型智能提升,任务失败的主要原因已从智能失败转变为上下文失败。
智能体所需的关键上下文
除基础代码文件、文档访问和代码执行能力外,智能体更需要理解以下深层上下文:
现状挑战与方向
当前智能体仅能获取约20%的相关上下文,且面临以下问题:
