Hard disk partitioning on PCs is one of those confusing areas, full ofpeculiar features and apparently random limitations, especially thewhole primary partitions versus extended partitions thing.

Fortunately, it's actually fairly simple:

• primary partitions are just a fixed size array in the firstsector (the master boot record, among other things).
• extended partitions are a chain (a linked list).

Each extended partition starts with a sector (the ' extended masterboot record ')that describes how big it is and then points to

I recently used ' help() ' on one of my own internal modules, mostly asa quick way to browse the entire function/class collection in one go.Now, I'm kind of a slacker when it comes to using docstrings (for somereason I prefer comments before the function), so I didn't expect tosee very much in the help() output.

Much to my surprise I saw things like:

While the Berkeley FFS and derivatives like Solaris UFS are much, muchbetter at dealing with fragmentation than the original V7 filesystem(which continued on into System V before SysVR4), they can actually getfragmented over time to a degree that matters.

Traditional Unix, Solaris included, really doesn't have any tools fordefragmenting filesystems; instead, you get to to do it the bruteforce way, by copying everything into a clear filesystem. With SolarisDisksuite and mirrored disks, it is possible to do this

• hit a highwater of 36 connections being checked at once, set onSaturday (today).

Message volume is up from last week ,but I'm not too surprised; this is the start of classes

What iTunes and similar online services are really selling isconvenience and guilt-avoidance, with a small side order of helpingout the artists. They're manifestly not selling the music itself (orvideos or etc), since you can find them online yourself if you look hardenough.

The 'helping out the artists' bit is currently only a small side orderbecause most everyone understands at some level how little of the moneyinvolved actually makes it to the artists.

The guilt-avoidance is not a good long

Dear vendors:

When I am visiting your fine web pages, I am often most trying to findwhich of your products have a particular feature that I need. Makingme carefully check through all of your products, examining their modelnumbers (if I am lucky) or each of their detailed feature pages (if I amnot) is not productive and does not make me very happy.

(It does make me thankful for Firefox's tabs.)

So what I would really like to see is a product feature
