雲夢若耶: 綰龍臺

《捃摭精華》曰:李神遇以楓溪鐵造綰龍臺為燈,安花八層,間以三縫錦褾,點紫綾油,燃鳳縷。

捃摭精華記載,李神遇用楓溪之鐵造綰龍臺製造燈,安八層花,中間用三縫錦褾間隔,點的是紫綾油,燃的是彩線捻成的燈芯。

燈也許在,臺呢?臺若不在,燈呢?

HAProxy, The Reliable, High Performance TCP/HTTP Load Balancer

high availabilityload balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware. Its mode of operation makes its integration into existing architectures very easy and riskless, while still offering the possibility not to expose fragile web servers to the Net, such as below :

Currently, two major versions are supported (NB: comment is outdated):

  • version 1.3 – content switching and extreme loads
    This version has brought a lot of new features and improvements over 1.2, among which content switching to select a server pool based on any request criteria, ACL to write content switching rules, wider choice of load-balancing algorithms for better integration,content inspection allowing to block unexpected protocols, transparent proxy under Linux, which allows to directly connect to the server using the client’s IP address, kernel TCP splicing to forward data between the two sides without copy in order to reach multi-gigabit data rates, layered design separating sockets, TCP and HTTP processing for more robust and faster processing and easier evolutions, fast and fair scheduler allowing better QoS by assigning priorities to some tasks, session rate limiting for colocated environments, etc…
  • version 1.2 – opening the way to very high traffic sites
    The same as 1.1 with some new features such as poll/epoll support for very large number of sessions, IPv6 on the client side,application cookieshot-reconfigurationadvanced dynamic load regulationTCP keepalivesource hashweighted load balancingrbtree-based scheduler, and a nice Web status page. This code is in deep feature freeze and may eventually receive critical fixes only.

根据来自CU的说法:HAProxy是一个反向代理服务器,支持双机热备支持虚拟主机,但其配置简单,拥有非常不错的服务器健康检查功能,当其代理的后端服务器出现故障,HAProxy会自动将该服务器摘除,故障恢复后再自动将该服务器加入。新的1.3引入了frontend,backend,frontend根据任意HTTP请求头内容做规则匹配,然后把请求定向到相关的backend.
新版本修正了很多会导致服务暂停的问题,增加一些小的但是非常有用的新功能,例如配置文件切分;配置错误提示信息更加友善;支持超过65000的并发会话;同时可以将某服务器的权重设为0等等。

但是看来好象中能说算是。

雲夢若耶: 山神報豐

《鳳翔退耕傳》曰:琴叟耕鳳嶺之田,以虎紋巾裹犁推之,曰:「勞吾躬耕,山神必以豐年相報。」已而果然。

購翔退耕傳中記載了一位琴叟,他老人家在耕鳳嶺之田之時,用虎紋幣裹上犁,然後推著它,大概是以虎拉犁之意,然後說:讓我親自耕田,山神應該報我以豐收啊。最後的結果是果然。

果然,神焉、仙跡焉?

雲夢若耶: 芋魁遭遇

《三賢典語》曰:李華燒三城絕品炭,以龍腦裹芋魁煨之,擊爐曰:「芋魁遭遇矣」。

三賢典語稱,李華先生燒三城中絕品之炭,用龍腦裹芋頭煨烤,一邊烤一邊敲著爐子說“芋頭啊芋頭,今天算是遇上了”。

這生活何其奢。

1. 芋魁

芋的块茎。亦泛称薯类植物的块茎。时有谣歌曰:‘败我陂者翟子威,饴我大豆,亨我芋魁。’
《后汉书·方术传上·许杨》李贤 注:“芋魁,芋根也。”芋魁徒软美,松粉藉餦餭。
明 徐渭《薯蓣》诗五十年来羹芋魁,顿令泽国生蒿莱。
清 顾炎武《兄子言及开吴淞江之役书此示之》诗

2.芋魁豆飯
喻食物粗劣。语本《汉书·翟方进传》:“ 王莽 时常枯旱,郡中追怨 方进 ,童謡曰:‘坏陂谁? 翟子威 。饭我豆食羹芋魁。’” 颜师古 注:“羹芋魁者,以芋根为羹也。” 清 唐孙华 《夏日园居杂咏》之十:“苦草王瓜随地满,芋魁豆饭一生过。”亦作“ 芋魁饭豆 ”。 宋 苏轼 《庆源宣义王丈有书来求红带既已遗之且作诗为戏》:“拂衣自注下下考,芋魁饭豆吾岂无。

骑行日记, 22, 无题

今天心情不好。白天如是,晚上上更如是。本来一度很开心。算了。不只是无题,还无聊得很。但是骑了就要写,即便明天天塌地陷。算是一种坚持吧。

另,祥和花园-胜利桥北637车的师傅,祝你开的车以后喇叭全部失效如何,反正市内用不到,当你想没事按着玩的时候,因为不再响就不会影响到别人了。
