because you can probably work with a random 1% of the rows and make your life a whole lot easier. assuming you define "random" well enough

nerdz posted:am i a terrible programmer for not doing tdd The advantages of TDD are: - You think about what your code should do and expose as an interface before jumping in (write it with the user in mind, not the programmer) - Your tests are more about what the code should do than crystallizing what crappy code you wrote is doing right now - It's a shitload more boring to write code after everything is done, than making it part of the design process

Shaggar posted:it doesn't pause the process. VMware runs the same instance on both hosts simultaneously and switches the I/O. its transparent to clients. the only restrictions are that you need the hosts to be on the same disk+network. vmware uses it for both HA (same instance runs on both hosts all the time) and for migrating guests. there's a much simpler reason. reserving the ability to migrate VMs between hosts means spending more money on network infrastructure and storage than you otherwise would. being migrated when a host fails is not part of amazon's SLA. why would they spend a single nickel on something they never promised to customers?

Bloody posted:where's the data import tool live? is it from visual studio or its installed as part of sql server management studio so it would be in a related sql server start menu folder. Bloody posted:also is 10 billion rows too many to be able to use half decently at all once its loaded it depends on ur server, the data quality, and ur schema. also if this is a local instance of sql express theres a 12gb db size limit.

lol azure's SLA is utter poo pooquote:For Cloud Services, we guarantee that when you deploy two or more role instances in different fault and upgrade domains, your Internet facing roles will have external connectivity at least 99.95% of the time. it's no worse than amazon or google or joyent. because all of their SLAs are poo poo. "if you stand up a service as a geographically distributed entity, some of your poo poo will be up most of the time"

99.95% sounds not so bad but that's half a day of downtime a year half a day of downtime in your highly available, multi-datacenter infrastructure lol

FamDav posted:its actually more like 4 1/2 hours. sorry, half a business day. but remember, this is the SLA for everything being down. how much poo poo has to be broken that multiple datacenters are simultaneously unavailable? under this SLA microsoft will refund you $0 and pay $0 in penalties in the event that they have a multi-datacenter failure for four and a half hours that takes your business down under normal circumstances, like an entire datacenter going dark with no explanation, you also get $0. or amazon deciding to reboot your instances w/out permission to fix a bug. cloud vendors don't have SLAs, they have agreements on the level of non-service

Bloody posted:its my own computer oh ok, then yeah lol go nuts with any sql server but mysql for certain queries it can be faster to just read the data from cvs or whatever, but then you have to deal with merging and handling larger-than-memroy stuff, so it's worth it to get the sql server to do it for you, make sure you have indices if you want to run ad-hoc queries and have several beefy machines and don't care if you lose data it could be worth it to look in to elasticserach /w kibana. on just one server it will be a lot slower than a real sql server, but it's so easy to make a cluster you can literally do it by accident

There's only SLA with some customers that asked for one in a contract, but we track all uptime and incidents in https://status.heroku.com/uptime and https://status.heroku.com/

heroku's uptime count excludes applications that aren't in fully redundant configurations but given that heroku is backed by aws we can't very well expect them to be more reliable than the underpinning

Notorious b.s.d. posted:heroku's uptime count excludes applications that aren't in fully redundant configurations It's defined there: https://devcenter.heroku.com/articles/heroku-status#uptime-calculation quote:Heroku is a distributed platform spread across many different datacenters and components. During any given incident, it is rare for all applications running on the platform to be affected. For this reason, we report our uptime as an average derived from the number of affected applications. the "single idled web dyno" that are excluded mean free applications that are automatically swapped out after 1h of inactivity and are not running at the time of the incident. There is no running application excluded, and if your app has a single instance, runs for free, and is hit by an error, this is accounted for in the uptime metric.

fritz posted:actually that's a little bit worrying, if your data is so heterogenous that you cant do random sampling, are you going to be able to draw any meaningful conclusions at all Dunno yet! I don't want to make any assumptions yet. It's definitely a very hetero set in that it's a whole bunch of low dimensional but similar and potentially related independent time serieses glommed into a single format/collection (for better or worse) I don't really expect to ever do much of anything on the entire set at once - I will be sampling from it for practically everything, just not randomly.
