Automation changes as systems grow

Over the time I've worked in system administration, I've observed acommon pattern that I will summarize this way:

As your system count grows, you wind up automating the automation.

Here is the levels that I've seen people (myself included) go through:

  • managing systems by hand, one by one.
  • using tools that let you run a command on all of your systems orclasses of your systems.
  • automating things for clusters, so that you don't have to explicitlyrun commands on

What the co_names attribute on Python code objects is

As a trap for the unwary, Python code objects have both a co_names and a co_varnames attribute. Since I just confused myself aboutwhich was what the other day , here is what the co_names one is.

Put simply, co_names is a tuple of names of globals and attributesthat are used by the function's code. For example, if you have ' a =self.bar() ' in the function, the ' bar ' will show up in co_

Why apt is always going to be faster than yum

One of the things that people report (to put it politely) when theyswitch between a Debian-derived distribution and Fedora is that apt isfaster than yum . This is indeed the case, and it is always going to bethe case, because yum is simply doing far more work than apt is.

(Whether or not the speed difference matters in practice is anotherdebate. It doesn't bother me, but then I use fairly fast and beefymachines.)

As I understand it, the different amount


Why you can't stop 'abuse' of file sharing services

I hope that everyone will agree that filtering 'banned' content(whatever that is in your local jurisdiction) is in practiceimpossible. Users are happy to rename files and otherwise obscurethem in order to evade machine inspection, and no one can afford tohand audit everything that is being shared.

(Arguing that people must hand audit things anyways basicallyamounts to arguing that no one can run a file sharing service.)

This means that the only thing you can really do to deter this bannedcontent is to make your

Greasemonkey xhr redirection in Firefox 3

I found that my rssget script is not working in Firefox 3 beta for some of the link. After some investigation, the cause seems to be the difference in redirection handling. In Firefox 2, when GM_xmlhttpRequest() is fired, it would follow status like 302 to do the redirection to return the correct page response to the onload function. However, in Firefox 3, the onload would receive a status like 302 and thus the script would fail.

I don’t know whether it
