Facebooks' MySQL is only used as the SOR.  Queries and all that fun web-scale stuff is mostly cached, piped, and offloaded into a variety of fun and definitely not SQL stuff :)

Saying the exchange rate is driven by the supply and demand of a currency is a tautological argument.  It misleadingly entices you to think that the exchange rate is controlled interior to that currency. What determines the motion of the exchange rate is the external trade demand for goods...

Lol.  You'd need a central bank and government for that.

I'm curious.  MongoDB uses memory mapped files... so what were you using the RAM disk for?

I like the topic-level filtering idea much better.  I do read the occasional gossip thread (obviously) but being able to personally delist them once they become toxic or just banter would be a welcomed alternative.

Somewhere there must be a language difference because I keep getting that same response from you in other threads.  I do read...  To which I made my rant about showing some empathy to fellow community members and not automatically bucketing anyone who doesn't show the same level of engagement...

Being serious here for a moment: When other community peers bother to suggest 'go discuss that in the Cest Pit' obviously something is wrong...  or would you rather seriously entertain the notion that they're all just power-tripping entitled brats.  Sure, mob mentality takes hold sometimes and...

The only people who lose out are the drama queens. They'll lose more than half of their potential audience according to the current polls. Has anyone thought about their rights? Opt out is censorship of freespeech!

Let's back up a bit.  What do you mean you have a centos openvz?  Are you trying to install the slave on a VPS?  

Repo steps tend to help.   BTW, "I installed it" tends not to be enough, for paid or open source.   Paid support will hand-hold you through the steps asking you to clarify how you got to the stage you're at, without being patronizing.  But since you're coming at it as a free/community user...

Kinda like running nmap isn't technically illegal, but there aren't any good reasons one would be doing so on a network you don't own.  The people running the Captcha solvers typically aren't the ones spamming - the underground/spam network is pretty specialized and tiered - so it always comes...

Sounds like you want to basically build your own ghost specific PaaS.   I'd suggest build your own performant proxy (eg. https://github.com/nodejitsu/node-http-proxy) and have it do the state and request queue management.  That'll give you the power to block on that initial wakeup request...

Ya, use anything really that's has built-in geohashing.  Map-reduce isn't known to be... um... fast or efficient. Since wlanboy is an astute tinkerer who actually takes time to understand stuff (which I wholly encourage), here's a primer link to geohashing http://www.bigfastblog.com/geohash-intro

You know, MongoDB has geospatial indexes and queries. http://docs.mongodb.org/manual/applications/geospatial-indexes/ Bypass the script calculation and just use the built-in geoNear http://docs.mongodb.org/manual/reference/command/geoNear/#dbcmd.geoNear

If you're getting headaches/eyestrain from the monitor brightness, get a desk lamp and point it at the wall behind the monitor for bias lighting (some go as far as to get LED kits).

https://www.google.com/#q=site:gatsby.im edit: google geoloc totally fails.  use the query "site:gatsby.im" in the search bar if the above link fails for you.

For the lulz I'd imagine.  It's kinda gotten to that stage where seeing which fish will take the bait is as entertaining as any possible story itself.  I blame Fox News Channel.  :P

It kinda begs the question... if more than two servers and redundant power is the bare minimum, why not add redundant switches, networking, and AC?  Tier 1 cert for what it's worth, has zero redundancy; and really almost any reasonably cabled server room suffices.
