Read/Write Web
當人們談起 Web2.0 時，其中一個特質，就是由讀 (Read) 變成讀寫 (Read/Write) 的雙向關係。因此，你大概可以知道 Read/Write Web 是談甚麼了：Web2.0 科技產品、新聞、事件、分析等等。與其他的 Web2
'Argument list too long' is a misleading message
If you try to run a command with too many command line arguments, youget an 'Argument list too long' error (technically you get an E2BIG error from the kernel, which is then mapped into this error string byyour shell). There's a bunch of workarounds for this problem, such asusing xargs .
However, the error message is actually somewhat misleading. As oldUnix hands know (and new ones generally don't), the kernel's sizelimit on exec(
Getting source RPMs with yumdownloader
In theory, the yumdownloader program that is part of the yum-utils package will download the source RPMs if you want it to. In practice Ispent a long time having it not work on my Fedora Core 6 machines, untilI read yet another bland bit of advice telling me to use it and decidedto figure out just what was going on.

How NFS is unreliable for file-based locking
You hear a lot about how NFS is unreliable for file-based locking,but you rarely hear how and why, and understanding the details helpsin understanding what can go wrong. The fundamental source of NFS'sunreliability issue here is what I'll call the replay issue.
The communication between NFS clients and NFS servers is unreliable;both requests and replies can be dropped. Only the client worries aboutthis, and it uses a simple approach: if it didn't get an answer to itsrequest,
異端
魯迅之死，因為病，也因為難以企及的任性。他長期沉溺於毀損健康的作息，拒絕休息，不肯療養。他不是尋常的利他主義者，但也不肯利己。他確曾試著活下去，像一位人子與人父，同時存心熬乾性命，朝死路走——文學塑造
