About SIEVE Cache

A cache algorithm called [SIEVE][sieve-website] was announced in 2023. It claims to be simpler than LRU, and indeed it is a fairly simple algorithm, but it is said to perform as well as existing superior cache algorithms such as S3-FIFO and TinyLFU.

Dealing with the Linux OOM Killer at the program level

Do this in cases when you dont want to change the os-level settings, but only want to disable the OOM killer for a single process. This is useful when youre on a shared machine/server.

The OOM killer uses the process level metric called oom_score_adj to decide if/when to kill a process. This file is present in /proc/$pid/oom_score_adj. The oom_score_adj can vary from -1000 to 1000, by default it is 0.

You can add a large negative score to this file to reduce the probability of your process getting picked and terminated by OOM killer. When you set it to -1000, it can use 100% memory and still avoid getting terminated by OOM killer.

Mining under linux

Disclaimer

I'm in no case responsible for fried hardware, erased software or burning down houses. Make sure your miners are always well cooled.

General recommendation

Though you can easily mix nVidia and AMD in the same rig with Linux, it's recommended to use a different thread for each platform so a Driver crash doesn't bring the whole rig down. It should be noted however, that some mining software have trouble when both architecture are found on the same rig.

AWK 简明教程

提炼自CoolShell：http://coolshell.cn/articles/9070.html

有一些网友看了前两天的《Linux下应该知道的技巧》希望我能教教他们用awk和sed，所以，出现了这篇文章。我估计这些80后的年轻朋友可能对awk/sed这类上古神器有点陌生了，所以需要我这个老家伙来炒炒冷饭。况且，AWK是贝尔实验室1977年搞出来的文本出现神器，今年是蛇年，是AWK的本命年，而且年纪和我相仿，所以非常有必要为他写篇文章。

之所以叫AWK是因为其取了三位创始人 Alfred Aho，Peter Weinberger, 和 Brian Kernighan 的Family Name的首字符。要学AWK，就得提一提AWK的一本相当经典的书《The AWK Programming Language》，它在豆瓣上的评分是9.4分！在亚马逊上居然卖1022.30元。

我在这里的教程并不想面面俱到，本文和我之前的Go语言简介一样，全是示例，基本无废话。
