I've recently been doing some work on classes derived from list and tuple that fiddle with the behavior of __getitem__ , and ran intoa couple of surprises that I am going to write down so that I rememberthem in the future:

• for the simple ' obj[i:j] ' case, __getitem__ is not called ifthe class has a __getslice__ method. list and tuple both do,despite the method being labeled as deprecated since Python 2.

Consider various server push technologies, where things come to youinstead of you having to seek them out: email, instant messaging,voice over IP phone server, and even text messaging on cell phones.All of them have spam problems (generally growing).

This is not a coincidence. Any server push technology will get overrunby spammers, because server push inherently gives them access topeople and is thus very, very attractive. As a consumer of server pushtechnology, your only recourse from the onslaught is to hide

Long ago, when I griped about Slashdot's redesign ,Oscar del Rio left a comment suggesting that I use Firefox's minimumfont size setting to cut this off. This isn't an approach that I likefor a relatively simple reason: I'm willing to have some text set small,just not the main text.

I want websites to be able to set less important things in small fontsizes, but I don't want them shrinking down the text I'm actually hereto read

The Linux iSCSI project keeps itsdocumentation in a world-editable wiki. I should really say kept,because it's hard to find much usable documentation in the wiki at themoment; most of the pages are overgrown with wiki spam. Some pages havehad a thousand edits in two days , all of them spam. All of this makesthe project's wiki an unfortunately excellent illustration of why mostopen wikis are doomed.

The problem is that there are just more spammers out there automatingtheir attacks than most

Recently a co-worker pointed out that the downside to giving machines distinctive hostnames is that users become attachedto them, and when you introduce newer, better machines the users don'tmigrate to them. Once I thought about it, this made sense; after all,by naming things we make them distinct, and thus no longer quite sogeneric and equivalent.

(At this point I am tempted to think thoughts about brand loyaltyand the distinctiveness of brand logos.)

One contributing factor is that with many generic
