TravisSc6tt··on Ask HN: How do you manage a bunch of microservices?
Datadog is good for metrics, but I'm more curious about the deployment side of things. For example, let's say I just made an update to a service's API that requires deploying new versions of 3 microservices. I want to (1) be able to locally deploy and test the 3 new versions, and (2) deploy all 3 versions at the same time. This ends up being super tedious because I have to do a lot of manual work just to push a (potentially minor) update.
TravisSc6tt··on Review: We do not recommend the $299 Oculus Quest 2 as your next VR system
> Part of that comes from Facebook's aggressive policy about making Facebook social media accounts (whose terms of service revolve around a "real name" policy) mandatory to use new Oculus VR headsets, including the Quest 2.

That's all I need to know to stay away from this. 300 bucks and you still need to use a Facebook account?? No thanks

TravisSc6tt··on Ask HN: Is there any interest in a “curated” online store?
I see what you're saying, but I'm not curating products--I'm curating online stores on which users can then find products. Does that make sense?
TravisSc6tt··on Ask HN: Is there any interest in a “curated” online store?
I remember DMOZ, but this site wouldn't just be a directory of online stores. It would search a set of reputable online stores and show you results from them. Unless I'm missing your point?
TravisSc6tt··on Ask HN: Is there any interest in a “curated” online store?
That's a good point. Initially I would only include big-name stores. If you searched for filing drawers you may see results from Office Depot, Staples, or directly from whoever makes filing drawers. When you order from those websites, you know you're getting a product shipped directly from them. When you order from Amazon, you don't know who is selling you the product (more often than not it's from a third-party seller).

The dynasm-rs package looks really useful for projects like this. Hope it helps Rust gains more steam in the PL community

I've noticed that companies' stock prices don't always correlate to the performance of their past quarter. Wonder why

This reminds me back when people built "supercomputers" by clustering hundreds of Pis.
TravisSc6tt··on Shared Libraries: Understanding Dynamic Loading
Copying the cheat sheet over for reference:

Find out what dependencies are missing with ldd <executable>. If you don’t identify them, you can check if they are direct dependencies by running readelf -d <executable> | grep NEEDED. Make sure the dependencies actually exist. Maybe you forgot to compile them or move them to a libs directory? Find out where dependencies are searched by using LD_DEBUG=libs ldd <executable>. If you need to add a directory to the search: Ad-hoc: add the directory to the LD_LIBRARY_PATH environment variable. Baked in the file: add the directory to the executable or shared library’s rpath or runpath by passing -Wl,-rpath,<dir> (for rpath) or -Wl,--enable-new-dtags,-rpath,<dir> (for runpath). Use $ORIGIN for paths relative to the executable. If ldd shows that no dependencies are missing, see if your application has elevated privileges. If so, ldd might lie. See security concerns above.

TravisSc6tt··on Fulgurite
Cool page, that was a fun read!

I found this particularly interesting: Fulgurites are homologous to Lichtenberg figures, which are the branching patterns produced on surfaces of insulators during dielectric breakdown by high-voltage discharges, such as lightning.

Interesting read, thanks for posting!

I think this is the key: consistent effort.
