latest nlog or older nlog + nlog contrib has support for correlation ids as a logging variable so you don't even need to do any extra work.

necrotic posted:well its the typed javascript object serialization format and javascript only has floats this. javascript has nothing more precise than floats. if you deal with monetary stuff, for example, you really need to be disciplined about making sure your JS's only job is to accept the user-entered values and then ship them to something written in a less garbo language to do the actual math on them.

Corla Plankun posted:why doesnt null equal null in psql null isn't a value, it's the absence of a value in sql at least so, you'e not asking if it equals itself, you're asking if one missing piece of data is the same as another missing piece well, most of the time. sometimes in sql null does equal null when you're doing operations over the same column

its kind of gross since it limits your input formats to the api to json, but if you're only doing json then meh. the only thing is it makes it sound like you might be manually parsing json instead of using a formatter and normal model binding.

i've got the normal model binding going in the controller, i suppose there's probably a way to bind the model in a handler thing? im making a DelegatingHandler and sticking it in my HttpConfiguration

maybe i should be logging from the controller endpoint where the request content has more meaningful context. or maybe log from both the generic handler and the endpoint?

welp doing a few db inserts has absolutely ruined my application for some reason. was good at 2k requests per second with no db stuff, now some simple db logging is basically broken at 100 requests per second

it looks something like: using(var conn = new NpgsqlConnection(connectionString)) { await conn.OpenAsync(); using(var query = new NpgsqlCommand()) { query.connection = conn; query.command = "insert blah"; query.parameters.addwithvalue("blah", blah, blah); await query.ExecuteNonQueryAsync(); } using(var query = new NpgsqlCommand()) { query.connection = conn; query.command = "insert blah"; query.parameters.addwithvalue("blah", blah, blah); await query.ExecuteNonQueryAsync(); } } and then under anything vaguely resembling a load it completely melts

it seems like running two db inserts every time my controller gets hit is not ideal also doing parameterized multi-row inserts feels hacky? like my model is just an array of poo poo that im passed usually as a json array of poo poo and so i want to shove the whole thing in the db but i wanna do that reasonably quickly so i wanna do a multi-row insert so im doin like for(var i = 0; i < fart.length; i++) cmd += $(@foo{i}, @butt{i})," cmd = cmd.Substring(0, cmd.length-1); and just like mashing strings together and poo poo myself and then doing another loop to AddWithValue all of those parameters i just mashed into a string and like ??? idk i feel like this shouldnt require so much string janitoring? i like that half of the results i find for multi-row ado.net inserts are trivially vulnerable to sqli Bloody fucked around with this message at 20:45 on Nov 3, 2016 |

The connection creation is probably your biggest overhead if you've not got connection pooling going on, but 100 requests per second seems low even taking that into account.

i dunno! how does npgsql connection pooling work? also i fudged together a bulk insert command and it is way faster than the non-bulk insert like 10x faster

qntm posted:"poor culture fit" Looks like they translated this into a slightly more prosaic form: Recruiter posted:Thanks for following up and I wanted to circle back with you in regards to your previous email. Unfortunately due to HR policies, we cannot provide specific candidate feedback. Took my second application for an SRE position though, I seem to be missing the secret handshake to get a terrible programmer role. I'm starting to wonder about their SWE roles as they appear to have no logging or monitoring on anything in production and many questions were about inspecting what an app is doing at runtime.

I thought the sql connections got auto pooled or something? so even if you close the connection in code or dispose of it it actually gets retained in the background and reused or something. i read like one tutorial today and realised that i know nothing and am actually just stack overflowing myself to success
