Re: SG, yeah I wasnt doing any cloud stuff when that was the case. Never had to restart anything for an SG change and this must be at least 5-6 years..
IAM Role change is more recent though

I like Taleb's books, but he does predict doom and gloom all the time - a broken clock is right twice a day after all
He is such an interesting character to me. I've read a few of his books and some principles he brings up are super interesting and overlooked imo, while majority of the stuff he writes about uses the most handwave-y explanations.
buzzdenver commented on I got OpenTelemetry to work. But why was it so complicated? iconsolutions.com/blog/i-... · Posted by u/paltaie
It is as complicated as you want or need it to be. You can avoid any magic and stick to a subset that is easy to reason about and brings the most value in your context.
For our team, it is very simple:
* we use a library send traces and traces only[0]. They bring the most value for observing applications and can contain all the data the other types can contain. Basically hash-maps vs strings and floats.
* we use manual instrumentation as opposed to automatic - we are deliberate in what we observe and have great understand of what emits the spans. We have naming conventions that match our code organization.
* we use two different backends - an affordable 3rd party service and an all-on-one Jaeger install (just run 1 executable or docker container) that doesn't save the spans on disk for local development. The second is mostly for piece of mind of team members that they are not going to flood the third party service.
[0] We have a previous setup to monitor infrastructure and in our case we don't see a lot of value of ingesting all the infrastructure logs and metrics. I think it is early days for OTEL metrics and logs, but the vendors don't tell you this.
Mind sharing that that affordable 3rd party service is?

Lol, that was my first reaction too. Funny how much language has changed in about 100 years.
Could you paste the regex portion of it please? Possibly some efficiencies to be gained there. You could also split the file into smaller chunks and then check the boundaries of the chunks.
Yes, breaking it up would work, but that is not a solution for streams.
The regex is dead simple: /Authorization: Basic (.*)\ngrant_type=refresh_token/ "." does not match newline, so I'm basically looking two lines that conform to a template.
Specific cases can be transformed with some grep/awk magic, but IMO the concept of pattern matching against a stream is interesting regardless.

For those of us who are only good at derivation: are these problems like chess where a computer will always beat a human?
Note that System76 laptops are not built or designed by them. They're whitelabeled.
These Thelio desktops are in-house, and they are way better than the laptops.
That's great info. I have an Adder laptop and both my hardware and software experience are poor...

Running this code on an "on-prem" AMD EPYC 9454P with 12 x 64 GB DIMMs:
1 37.4
2 73.3
3 107.3
4 141.4
5 171.6
6 199.5
7 226.0
8 251.1
9 235.4
10 243.0
11 264.5
12 281.9
13 303.7
14 323.0
15 339.6

32 364.9
So around 3x of what AWS has? I guess this is more about what motherboard they have, and not an on-prem vs cloud difference.
