Your current vendor probably knows how much it would cost for you to move to another vendor (quite possibly to more significant digits than *you* know). They also know exactly how much they're making/losing on SLA issues, and what percent of the move cost you're willing to tolerate - there's probably very few of us that can get away with being righteous and principled and spending $100K on a move to a new vendor over a $980 SLA issue. And even those of us who *can* do that probably can't do it a second time anytime soon. Of course, YMMV - spending $25K to get out of a contract with somebody who's already shafted you for $12K of SLA rebates and shows no sign of stopping is probably justifiable by almost all of us.... But I think Barry was asking specifically about the vendor who nickels and dimes you precisely because they know it's not enough to make a business case for moving.

Time Series databases

I'd absolutely love to know more about the algorithms and math > behind something like kdb+ KX publish a bunch of information about their product. Their lineage goes back to APL and the J language, both of which found most of their users in financial services. However, the general issue of time-series databases is more interesting. Google will take you to lots of research using keywords like: time-series database delta wavelet search indexing maxima Of course, don't use them all at once. To give you a flavor of the stuff that people have done, here is a slide presentation on compression and indexing that does not use averages like RRD does: http://www.cs.cmu.edu/~eugene/research/talks/major-extrema.ppt In addition to Google, it is a good idea to search CiteSeer http://citeseer.ist.psu.edu/ because it allows you to quickly track down references to other papers so you can read them all as a set. I don't think there are any full-blown open-source implementations that you could integrate into your own systems. There is stuff like Metakit http://www.equi4.com/metakit.html which stores data by column rather than by row. And people who have thought about how to efficiently store time-series probably cobbled together their own systems using bsddb or HDF5. If you are stuck in the SQL world, then check out these articles on star and snowflake schemas. http://en.wikipedia.org/wiki/Snowflake_schema http://en.wikipedia.org/wiki/Star_schema and follow up the references at the bottom of the page.

comcast spam policies
by doug＠safeport.com 07 Feb '07

07 Feb '07

I will not ask if anyone at Comcast has a clue, because I do not need any dvds. If this not correct, I would appreciate hearing from anyone whose clue-ness exceeds 15%. The rest is a description/rant about comcast's policy as described to me by a couple of tech people reached by following voice mail from 1-800-comcast which really should be 1-800-328-7448. The current comcast policy seems to be to backhole mail servers at random. Safeport's internal mail server which is the source of no spam (cause only we guys can use it) was blackholed either at random, or because we sent one email to a comcast customer. As if that is not bad enough only comcast customers can complain. The link given on the bounce email: http://www.comcast.net/help/faq/index.jsp?faq=SecurityMail_Policy18627 A pattern can apparently be discerned from a single email. The comcast guys at better at pattern recognition than most of us. Unlike AOL there is no person that can be mailed or contacted. Neither the link on the above page or blacklist_comcastnet(a)cable.comcast.com will respond except to (they claim) complains from individual customers. I guess the message is you better use gmail if you are a comcast customer. I really don't mean this to start an endless thread. On the off chance that there is someone who can and will explain the logic behind this policy and or perhaps do something about it, that would be useful. Otherwise there is not much point in berating idiots. _____ Douglas Denault http://www.safeport.com doug(a)safeport.com Voice: 301-469-8766 Fax: 301-469-0601

We do mostly ecommerce hosting and often our customers have their own dedicated servers blacklisted from sending email notifications of new orders to their home comcast addresses. We have to request unlisting regularly. David

No DNS operations BOF at NANOG39
by Keith Mitchell 06 Feb '07

06 Feb '07

Unfortunately due to not enough potential speakers, and pressure on BOF slots in the program, we have decided to not have this BOF this time around. My apologies for this - a number of potential speakers indicated they were preparing relevant work which would be more ready to present next time around, so hopefully at NANOG40.. If anyone would still like to have a DNS operations discussion in Toronto, I'm happy to facilitate this on an ad-hoc/informal basis. just drop me a note. Keith Mitchell OARC Programme Manager
