Mr Dog posted:I have a question about paging results sets returned by a REST server. The OData model uses a snapshot to send paginated results to the client, there is a standard mechanism to request paging and to request change notification, or both. When requesting both pagination and change tracking one must walk the entire result set before proceeding to the next change set. Kinda interesting but clunky implementation, used on OneDrive and many others.

Notorious b.s.d. posted:python, perl, and ruby are all reasonable choices for this sort of task. they're scripting languages, fiddling with unix poo poo in a hurry is what they're meant for. just use whichever one you like the most. pick perl if you have very little control over what is installed on the machines. perl is everywere and tbh for small scripts works very well. it's designed for unix janitoring it's weird around the edges, and yeah, some people still write perl 1 to 4 in 5, but that kinda died out. the camel book is well written. don't pick perl if you have to run poo poo on windows if you have to make things work on windows, use python python has a bunch of poo poo built in and it kinda does the job ok, but uh subprocess is full of mystery so maybe a wrapped unix janitoring library would help but ruby, well, honestly i'd advise against doing janitory scripts in ruby. the built ins are painful, and uh, the environment and tools are a little fast moving. i'd only use ruby for janitoring scripts if i could rely on something else to ensure ruby was there and up to date but uh, in the end if you're janitoring remote machines and not local machines, or ones where you're deploying things you're gonna end up writing bash either in a subset of bash, run under shell check, and in a perfect world it would commented as if it were assembly language or an ad-hoc yaml templating system that concatenates a bunch of strings together and runs bash scripts behind the scenes

like the whole "statelessness" thing is that "the protocol should not be stateful", or if you like, the messages sent over http can be re-ordered or sent across different links the point of this is that middleware does not have to do stateful tracking to provide useful services: it can add compression to output, resend GET requests, re-direct things

maybe your "pagination requests should be idempotent in the face of concurrent updates" is close to "i should be able to re-order my requests and get the same responses" and maybe "instead of sessions on the server and nothing on the client, the client should store some session data and pass it through" and maybe "each request carries it's own context, rather than sharing it with other requests i've made" and then "this request context is the state of the world when I made the request" to "the client stores the state, and transfers a representation of it to the server when making a request" rest says poo poo all about snapshot isolation, beyond "it's your problem to deal with but you should not bake session contexts into the messaging protocol"

rest: the ideas around having load balancers, caches, cgi-bin, links, forms are neat ways of building large interoperable systems at scale. heck, imagine if html was annotated so that it was so easy to screen-scrape/automate. restful: here is a list of urls and the json files they accept and return. if we ever need to return a new thing or change where something is you will have to update your list of urls. the following string values are special string values. please pray to god that the ints never go across 53 bits, amen

my thought process was something like "what if i do snapshot isolation except not really". you can't keep a transaction open for an extended period of time so you have to fake it up somehow and make some compromises along the way. if i can return all the rows at least once but some of them might change in the course of the iteration then i can live with that. i can probably do that if i don't give the client the ability to sort the data server-side but instead order the rows by creation timestamp, pass the last row id in a url state parameter, and use soft deletes so i can still pick up where i left off even if the anchor row gets deleted. or maybe do the opposite: let the client sort stuff but then not paginate and require the client to do "pagination" by constraining the result set using things it knows already. but you can't do both without full historical snapshots of every row which is just a pain in the dick and not something that sql databases are good at to begin with.

however you choose to represent your pagination token, make sure you at least obfuscate it and probably encrypt it. otherwise you will end up with customers who are dependent on your tokenization scheme and they will get angry when you want to change it.

Every single one I know of be all "lol gently caress this poo poo i'm out" blame mysql hibernate will happily provide a lot of SQL-isms via the horrid "HQL" poo poo, but not window functions, because window functions don't cleanly map to all backends. and we all know which backend is the problem.

mine is looking out the window and seeing how great the weather is outside and thinking to myself "hey maybe i should leave the office and go for a nice half hour walk without telling anyone" then do exactly that because i work with computers and nobody fucks with me over such trivialities then i go back inside to the comfortable air conditioning, think for a while, and press some buttons on my luxurious mechanical keyboard. for these actions i am paid more than is reasonable for a single human

so i bought an old amplifier that has multi input and multi zone output and can be controlled over rs232 im thinking about making an app that i can use to control it but im not quite sure which route i should go i could use a native app on my phone and communicate with a windows program that actually sends the commands over serial. planning on using c# and maybe webapi the other option is to have a completely phone independent, just have a web application (again in c#) that ill visit on my devices any opinions on how a terrible programmer should do this

build the webapi then you can build a page or an app to control it, or both

I"m tired and don't want to be at work today. My productivity is low and plummeting by the minute. Over the weekend I actually wrote some python code for a side project I don't even know why. Turns out I still hate dynamic typing.
