北京公幹之倒數篇
一連五日的北京公幹終於完成,辛苦工作的細節就不表了,說些開心事. A gotcha with the format of dump archives
Most archive formats, such as tarballs, cpio archives, and zip archives,interleave the file names (and their directory structure) with the filecontents. The dump filesystem backup program such as Solaris ufsdump do not. The dump archive format starts with an index that has all of thefilenames and the directory structure; after this comes the actual filecontent, labeled by inode number.
This has an important consequence for detecting damaged archives. In aninterleaved format like a tarfile, getting a full file listing requiresreading the

既然安心將最軟弱的一面交托給男人，既然放心男人有大能遮風擋雨。

Explaining some university staff peculiarities
I think that universities not having a return on investment as such may go at least part of the way to explain someweird university behaviors around staff. The core issue is that withoutan ROI it becomes difficult to see the cost of how staff spend theirtime.
(With a ROI for projects it is easy to see how having staff spend theirtime on a lower-ROI activity more or less directly costs you money.)
Not only does this effectively make staff into a constant sunk costregardless of what you have

A surprise with the Provides header in RPM
Normally, one of the things RPM bases dependencies on is package names.The problem with doing only this is packages that want to depend oncapabilities instead of specific packages; for example, that there issome mailer installed, not specifically that Sendmail is installed. Todeal with this, RPM introduced the Provides: directive, which lets anRPM package tell the overall RPM system that it is providing somethingthat is not obvious from its name, its files, and so on.
In implementing this, RPM has chosen to

Implementing a preforking network server in Python
I recently read a great explanation of thegeneral Apache 2 preforking server model ,and found it so lucid and simple that I was immediately inspired toimplement a generic preforking server myself. Their approach has a bitof overhead in parent/child communication, but it does mean that you donot have to pass file descriptors between processes; all you need issome way for the parent to talk with its children.
(Since Python's standard library doesn't have support for filedescriptor passing, the pragmatic advantages of
