You can go deeper and model a queue as a ring-esque buffer with a write head (can just be a serial id) and a read head. The read head starts at the same place as the write head and advances only up to the write head and no further via nextv

FWIW I use atuin ( https://atuin.sh/ ) and am reasonably happy with it, especially the infinite capacity & snapiness. Ignoring the sync features, I believe it's also sqlite backed when running in local-only mode.

When you measure latency, you’re measuring it based on requests. So in some bucket if you had a request take 2s and a request take 10s, you would say the average is 6s. This answers the question “how long should I expect a single request to

This is standard statistics terminology - E(X) is https://en.wikipedia.org/wiki/Expected_value . E_a is presumably Alice's perceived expected value. Var(X) is https://en.wikipedia.org/wiki/Var

This might speak to the craziness of the gstreamer plugin ecosystem - good/bad/ugly might be a fun maintenance mnemonic, but `voaacenc` is actually in `bad` - not `ugly`. Most plugins you'd want to use aren't in `good`.

I was recently in the market for one of these! I ended up going with https://github.com/dbohdan/recur due to the nice stdout and stdin handling. Though this has stdout/stderr pattern matching for failures which is

Facebook’s wormhole seems like a better approach here - just tailing the MySQL bin log gets you commit safety for messages without running into this kind of locking behavior.

IMO mermaid is awesome, but for two somewhat indirect reasons: - There’s an almost wysiwig editor for mermaid at https://www.mermaidchart.com/play . It’s very convenient and appropriately changes the layout as you draw arro

Agreed - concretely with-redefs forces single threaded test execution. So eg you can’t use the eftest multithreaded mode. Explicit dynamic bindings are better if you need something like this since those are thread local.

Usually the controversial decision for Clojure code highlighting is rainbow parens. This color scheme is horrific and unreadable (on mobile at least).

I don’t know about tires, but for brakes we already know how to make lower dust brakes - use drum brakes instead of disc brakes. The friction material is enclosed on drum brakes so much less of it just flies away.

So I might be putting words in your mouth, so please correct me if this is wrong. It seems like you don’t actually control the SIGTERM handler code. Otherwise you could just write something like: sigterm_handler() { make_healthcheck

Why the additional SUGUSR1 vs just doing those (failing health, sleeping) on SIGTERM?

Yes sorry for not qualifying - that’s right. IMO the liveness check is only rarely useful - but I've not really run any bleeding edge services on kube. I assume it’s more useful if you actually working on dangerous code - locking, thre

This is actually a fascinatingly complex problem. Some notes about the article: * The 20s delay before shutdown is called “lame duck mode.” As implemented it’s close to good, but not perfect. * When in lame duck mode you should fail the p

Talking of trees and caches, back in school I remember learning about splay trees. I’ve never actually seen one used in a production system though, I assume because of the poor concurrency. Has anyone heard of any systems with tree rebalanc

Presumably depends on the country and the laws. Keep in mind that Apple considers this a new interesting use case - not a killer feature for AirPods. They wouldn’t risk AirPod sales with a gray interpretation of the law.

Of course you’re right and you really want to avoid getting to GC thrashing. IMO people still miss the old +UseGCOverheadLimit on the new GCs. That said trying to enforce overhead limits with RSS limits also won’t end well. Java doesn’t mak

If your clojure pods are getting OOMKilled, you have a misconfigured JVM. The code (e.g. eval or not) mostly doesn't matter. If you have an actual memory leak in a JVM app what you want is an exception called java.lang.OutOfMemoryError

Would be great if it included sequential sampling as well: https://www.evanmiller.org/ab-testing/sequential.html . Especially given how A/B tests usually get run in product companies, a peek proof method helps qui

Easier to explain with coin flips. Let’s say we do 100 flips - we know the “most likely” thing to happen is 50 heads and 50 tails. The actual probability of that is C(100, 50) / 2^100 = 0.079. So about an 8% chance. You’re significantl

I’ve come to a similar conclusion about “self-service BI” myself but my solution is somewhat different. The solution I have is move the layer of abstraction higher: make extremely customizable dashboards but do not expose SQL to business us

I have the same issue with my router - it supports 1gbps but that’s a total over all ports. That total includes the WAN port. So the max throughout you can get from one port to the internet is half the max - 500 mbps.

I’m going to go for the esoteric opinion: MariaDB. Specifically to get system versioned tables. Imagine having the full change history of every single row for any odd task that you need without the performance penalty of keeping historical

I haven’t tried this framework, but just looking at some examples, the web sockets and sse seem a bit out of place. In a Loom world you’d expect these to use channels or queues or something similar in a loop - not callbacks. Callback hell i

Lol yes of course I meant 103. Though I’m ready for an http status code that’s like that: “I can’t give you what you want, but here’s something you didn’t even ask for instead.”

They mention this in the doc, but it seems like the future solution to preloading resources will involve HTTP Status 403 [1]. That seems like a great alternative to server push. Currently it seems like the best option is to use Transfer-Enc

This may not be a surprise to some, but when folks talk about reliability of the control plane, they usually think failure means their web service goes down. That’s not true. If you shot the kubernetes control plane, the individual servers

AWS availability zones (so like us-west-2b rather than us-west-2) are not the same between accounts. us-west-2b for you is something different than us-west-2b for everyone else.

Structural editing is basically a hard requirement with Clojure - I don't think you can realistically live without it. Paredit is fine, but it does take 2-3 months for your fingers to adapt. It would be even better if they didn't
