Mon Jan 30 07:23:52 EST 2017 Slept from eleven to five, when the rehab centers trash truck clanged the fuck out of their dumpster. Looks like we got maybe half an inch of snow overnight. Today, a high of twenty-seven and flurries in the afternoon. Two inches of snow tonight. Work: - Check server room environmental Temp is much improved. Humidity was not. - Review invoices Done. - Stand up testing containerized asterisk server in cloud No, got sidetracked with NAPTR and SRV DNS records for SIP. But useful. SIP clients, when configured to hit a SIP server by name (rather than by IP address), should make DNS queries for NAPTR and SRV records. When a query returns multiple SRV records for a host, each record has a _priority_ and a _weight_. Priority descends. SIP clients prefer the server with the first priority (i.e. use 10 not 50), and only try subsequent priority servers if the first server is unavailable. Weight is only considered between servers of the same priority. Clients are expected to distribute their requests among servers of the same priority in proportion to the weight of each server. For example, two servers have priority 5; one server has weight 70 and the other has weight 30; clients send 70% of their queries to the former. https://en.wikipedia.org/wiki/NAPTR_record https://en.wikipedia.org/wiki/SRV_record https://tools.ietf.org/html/rfc2915 https://www.ietf.org/rfc/rfc3263.txt [Paraphrasing https://anders.com/cms/264/] Consider a call to 2125551212@example.com. Given only the address, to what IP address, port, or protocol do we send this call? We're not even certain that example.com supports SIP or some other VoIP protocol. We start with a NAPTR query for the domain. One of the NAPTR records shows "SIP+D2U" (SIP over UDP), and has an "S" flag indicating that we should do a subsequent query for SRV records. Each SRV record returns a hostname with a priority and weight. Twenty minute walk at lunch. Glimpsed a couple of spots of blue sky, and the sun once. Home: - Healthy dinner Done. - Go to bed a little early Done. www.metafilter.com/164822/Bannon-now-on-National-Sec-Council-professionals-demoted-to-make-room#6897382 > One of those reasons is becoming clear now, because the Joint Chiefs are no longer on the National Security council. It consists entirely of Donald Trump, Reince Priebus, and Steve Bannon. So the decision to approve the targeted killing of a US citizen lies entirely and exclusively in the hands of Donald Trump, the head of the RNC's campaign finances, and a Nazi propagandist. Without review or oversight. http://zzarchov.blogspot.ca/2017/01/how-i-write-adventure-part-2-longer.html http://falsemachine.blogspot.ca/2017/01/how-i-make-adventure-part-1.html http://goblinpunch.blogspot.ca/2017/01/how-i-write-adventure.html Added to my Lua notes a little. https://roelof.info/projects/(2014)Pretty_Fly_For_A_Wifi/ > Pretty Fly For A Wifi is an overview of different self-made WIFI antennas. It is a combination of pots and pans, dishes and cans through which people from around the world give shape to their collective dream of making an alternative internet. Each of these objects tells part of the story of individuals and groups, who each in their own way try to reconfigure the internet’s infrastructure to achieve this goal. For this project I built, tested and documented these antennas and in the process revisited their histories, origins and uses. Breakfast: spinach, carrots, yogurt with berries, coffee Lunch: nuts Dinner: chicken breast, green beans, coleslaw, biscuit
