+ - Does SORBS matter anymore?-> 1

palegray.net writes "As an employee of a well-known VPS provider, I've been observing another employee's efforts to deal with irresponsible behavior on the part of SORBS, a well-known blacklist provider. Although their mission of providing a resource that system administrators can use to gauge the likelihood of spam originating from a particular IP or netblock is admirable, we've encountered consistent issues related to their assertions with a newly assigned block from ARIN. Jed puts it best:

We recently received a large allocation of IP addresses from ARIN and, to our chagrin, the block is listed on SORBS's list as dynamic IP space — a whole /20 worth of addresses. It has been listed since April and we received it in May. What this means is that to incoming mail servers, all of our customers in this block appear like home customers with a cable or DSL connection (who should not be sending mail).

Obviously, as a hosting company we assign a static to each VPS we provision. Our IP allocations are is in no way dynamic; customers may request an IP address change, but we don't receive many such requests. We always ask for justification, and the requests we approve are typically performed on a "one time only" basis. Jed continues:

I approached SORBS about the issue via their automatic contact system. It has been nearly two weeks since their "bot" replied to me and informed me that most of the block was not eligible for delisting due to the naming convention in our reverse DNS PTRs. We use:

liXXX-YYY.members.linode.com

What's wrong with that? It "looks" dynamic, they say.

Despite our attempts to reach out to SORBS, explain our position, and get our IP space delisted, we've being told that we must change our reverse DNS naming scheme across our entire network to be considered for delisting. Needless to say, we consider this a ridiculous proposition.

Our primary concern is that mail administrators are using SORBS to blindly drop mail based on the false "dynamic IP" assertion. Although we would consider such a practice to be irresponsible from an administrator's standpoint, this is an issue that's been raised by some of our customers, and we're concerned about the effect it may be having on their ability to deliver legitimate mail. We've always taken an aggressive stance against anything resembling spammy behavior on our network; we're all I.T. veterans, we all despise spam, and we promptly handle any reports of abuse related to our network. It's distressing to see this situation going unresolved. What advice do members of the Slashdot community have on this topic?"

Being weird is an automatic handicap. The current layout provides a wealth of data in a grid, something that can be represented in the simplest of data structures. If you're going to switch to circular and have strange shapes and free-floating elements, you need to make up for all the complexity you've added by showing significantly more correlation. This does not in the least. If you want to see alternative layouts that really give the current a run for its money, check out Stowe's.

+ - Why pitch monitors upwards?

When visiting my mom, after resetting her monitor to level, I return to find it pointed back up toward the sky."

There are probably a lot of ways to detect commercials. ReplayTV doesn't go by time. Think about what changes when a commercial comes on. The picture, the overscan area, the audio. All it'd have to do is watch for the audio to drastically change, like stereo to mono or cut in and out, the overscan area to drop in and out (closed captioning, XDS), and screen blanking. If two out of three happen, a commercial probably started.

Mega HTML Periodic Table 60

from the now-thats-a-massive-table dept.
Calcbert sent us a link to one of the best browser stress tests I've seen in awhile. Lucent has a Periodic Table of the Elements online that makes the tables in Slashdot seem nice and minimal. How does Gecko take on that beast? Maybe more important is the fact that I now know what Ununbium is. I thought it was a radioactive card game. Ooo knew? (god it must be late, my jokes actually worse than usual. Didn't know that was possible) Here's another one that has more data, but it doesn't have quitethe same stress testing potential. But now I know the half life of Ununbium too.

I tell them to turn to the study of mathematics, for it is only there that they might escape the lusts of the flesh. -- Thomas Mann, "The Magic Mountain"
