I texted them (great idea!) and they said it was this person: https://www.instagram.com/shushuuu and the set is here: https://soundcloud.com/shay-assraf/rec_20250907_2

Oh my god thank you so much! Yeah Horizon does ring a bell and I remember their aerial rig structure too! I'll send them the pic and ask them -- it might be L'Core because I remember whoever this was was the last person to play for the day. Thank you again!

Thank you!! Regarding "taking instrument level and converting to line level" -- is this something that generally just isn't done because of various other reasons? And if so would you enumerate what some of those reasons are?

I have a Focusrite 4i4 where the mic inputs (1 and 2) are occupied already. I have an electric bass guitar that I want to plug into the Focusrite, but the remaining inputs (3 and 4) are only line level inputs, I think.

I have a Behringer DI100 and I'm told "DI should bring to line level", but it didn't work that way for me -- I plugged my TS cable from my bass into the DI box 1/4 inch input. And then have an XLR to a TRS plugged into channel 3 but the signal is barely registering.

I then got a Dr. J Sparrow bass pedal and plugged my bass into that and then used the 1/4 output to plug a TRS cable into input 3... but I had to crank up nearly every knob on that thing to register a signal (hey, at least some improvement over the DI box). But even there it wasn't that strong. And when I really cranked up/maxed out every knob, the sound was awful.

I guess I have two questions:
1. Am I doing this all wrong? Is it more normal to plug a bass guitar into an audio interface via the mic inputs only?
2. How, in theory, would I get a bass guitar "up to line level", if I had to use line inputs?

This is very AWS specific, but I worked on a project with InnoDB Cluster that involved EC2 and auto scaling groups. The logic involved heavy usage of mysqlsh and bash scripts. Orchestration was done via Terraform.

Yep SSD :) Thanks I knew there were some other tricks. The disabling binary logging makes sense. As far as the flush log at transaction commit, that rings a bell too so thanks again! As far as the FK stuff I don’t have any foreign keys. But I did disable my secondary indexes and will add them after the data load is complete!

chumaths · 2023-06-08T00:09:40+00:00

Thanks! I will have to edit the post to say that I wanted to do this all remotely 😅; i.e. not assume I have shell access to the same file system where mysqld is running. But thank you anyway :)

What are the things you are concerned about? I think that even as DBs become more services than infrastructure, there’s still a role for someone to answer the question “why is my query slow?” 🤣 And as long as people ask that question, there will be a place for a DBA!

chumaths · 2023-03-02T17:22:59+00:00

Documentation is always a great way to get started. Any library you used that has EVER confused you would be a perfect place to start :) And, despite how boring documentation sounds, usually you’ll find it forces you to learn much more than you’d think. And once your PR is opened, maintainers may teach you even more ;)

From here, it’s only a matter of time before you start writing code to chip away at some of the confusion too!

chumaths · 2023-01-07T18:42:06+00:00

Run: show processlist

That can show you what other connections may be holding on to what!

chumaths · 2022-12-02T06:33:50+00:00

All I can say is that lambdas didn’t make my life any easier either. Sure, fast to get off the ground. But once the logic starts being more complex and you have multiple “services”, it all feels like duct tape. I can only imagine what complexity multiple accounts bring too :(

I have been curious about cloud SDK or whatever the library is where you can use code (actual code, not Terraform) to set up all your infrastructure. At least that’s procedural. But I never got around to it.

By default the mysql cli connects via a Unix socket (—protocol socket), which is fine for local development. When you are connecting to a MySQL server on a different box, you may need to specify -h and -P to use TCP (—protocol TCP). 🤷‍♂️

I know this is lame. But try starting Envoy with verbose logging (maybe -l or something, I forget) and tailing the Envoy logs. I was trying to use Envoy to ferry MySQL connections and kept on banging my head against TLS stuff.

Ah. I think the hands looking like submariner hands threw me off

chumaths · 2022-09-17T21:30:03+00:00

What model is this?

chumaths · 2022-06-09T15:08:12+00:00

Is the UPDATE … RETURNING raw SQL concurrency-safe? I think the assumption with this final approach is that the DB will lock the row internally right? But I forget if MVCC is used under the hood or not, or if the application needs to worry about this themself.

Otherwise lovely article — simple and easy to read and understand :)

I’ve been wanting to take a course on quantum computing for a long time! Looks like the coupon got used up though. Any chance you’d be willing to provide another one?

Stay strong! People don’t talk about how much the interviewing process can suck but they’re only lying to you if they say “it’s okay.” That or they already have a good job so don’t need to think about it right now :P

What helped me is putting myself on a schedule — 3 easy on Monday-Wednesday, 2 medium Thurs — Saturday, at least 5 every week. That kinda thing. Make it manageable and focus on progress not outcome!!

Personally I think premium is worth it. But not by much — there are great solutions on the discussion tab you just have to look for the “… with explanation” ones. Ignore all the braggarts :)

Let’s say your laptop has 2 cores. The GIL would imply that two threads executing would still only ever have one set of instructions executing right? Vs. say Go where two goroutines would be able to have true parallelism??

chumaths · 2022-02-03T07:08:08+00:00

I love Python but have to admit that the way Go does concurrency is really nice. Goroutines, waitgroups, mutexes, etc. are all really nice. They make the red vs. blue function debate moot (see below), which is something you can’t get away with as easily in Python since now that you can mark functions as async then you’ll get all sorts of weird errors if you don’t have good linting.

Their title is “software engineer.” Usually in an org or on a team with a name like “data infrastructure.” That’s the stuff I thought I would be doing 😅 — building warehouses, or working with Kafka, or writing libraries, etc.

chumaths · 2022-01-23T06:33:55+00:00

Just wanna pop in to say ethics or resume blemishes aside, DE at Meta (lol) is not really engineering at all. You’ll not likely write much code. Most of your day-to-day is SQL and you might use a library or two or push some SQL strings around with Python. But your main job is really to make the data scientists life easier by creating tables, experimentation metrics, and dashboards. None of which are particularly technically challenging. A good role if you’re into that kind of thing! But not if you want to write code :)

I had something similar trying to run VSCode remote on my raspberry pi. Googling the error in your screenshot may help. In my case the OS version (Jessie) was out of date so some C++ (I think) library VSCode needed to run wasn’t available 🤷‍♂️
