Tertiary Slashdotting

Today I noticed a spike in traffic coming from a post on Spread Firefox where I had made a comment. Not a ton of traffic, just ~10 ~15 hits from the same page on the same day, but that’s unusual for traffic from SFX posts—especially old ones. I checked to see if it had climbed into the site’s list of top posts (the usual explanation), but it wasn’t there. I just couldn’t figure out what was causing the traffic.

Then I realized the author of that post had another story show up on Slashdot today. I discovered this chain of links:

1. Slashdot: Just what has Microsoft been doing for IE 7?
2. Idealog: Microsoft Drops The Ball on Internet Explorer 7 Standards Compliance
3. SFX: Should NewsCloud.com Remain Firefox Only?
4. The Alternative Browser Alliance (via signature in comment)

You can see how powerful the Slashdot effect is, if it can cause a noticeable (if minor) spike in traffic to a page 3 degrees away!

Of course, it pales next to being linked from the ISC Handler’s Diary, which seems to have pulled in 15 10 times as many visitors in 2 days. (Thanks!)

Security Perspectives

When I worked at a computer lab in college, the main security focus was preventing lab visitors from screwing around too much with the computers. We just ran Windows NT and locked it down as hard as possible. The worst network-based threat I remember facing was WinNuke, and that was just as likely to be another lab tech. Some of the early email viruses started circulating while I was there, but since it was a public lab, we didn’t provide any email programs; people would telnet into the mail server and use Pine. (This was pre-Hotmail, too.)

In my wired-for-ethernet campus housing, however, all bets were off. I watched people remotely controlling each others’ computers as pranks, or discovering hackers had gotten onto their systems from halfway across the planet, and figured it was safer to use Linux most of the time. This actually got me in trouble with the network admin at one point, who decided I must be running a server and shut off my port. It did at least teach me to disable services that were turned on by default, though I saw no indication that anything on there was actually being abused.*

Then there were firewalled environments. Still back in college, we rigged up my parents’ house for a home network. My brother put together a Linux box to dial into the Internet and act as a gateway, and effectively everything inside the network was safe from direct attacks. No point in internal firewalls, and since everyone was savvy enough to avoid the really nasty stuff (which was easier at the time), virus scanners were only a precaution, rather than a necessity.

Aye, there’s the hub!

A few weeks ago I noticed that our network hub was getting disturbingly hot, so I started turning off the power strip when we weren’t home. After returning from San Diego, the first time we turned the computers back on, the hub started buzzing. However, it stopped after a few seconds.

So I should have thought of the hub immediately when the network started acting up today.

I had been on and off the computer and the net all morning with no noticeable problems, and Katie had been on for just a few minutes when it stopped loading websites. Read the rest of this entry »
