sciuruson Ruby on Rails in a week

Agreed, this is a great book. In the past I used to read and write a lot of Ruby. An earlier edition of the book was the single resource that taught me the most.

The only programming language book I've enjoyed and benefited from as much since then is Fluent Python.

sciuruson Woman allegedly impersonated prosecutor, dropped charges against herself

What are the types of mistakes that commonly lead to people being caught?

I'm asking, uh, for a friend. :-)

sciuruson Grafana Tempo, a scalable distributed tracing system

Honeycomb also stores traces in S3 and supports searching them via AWS lambda. I wonder if a model like that is useful for tempo, which doesn't seem to support search at all now.

sciuruson U.S. Accuses Google of Illegally Protecting Monopoly

Is the text of the DoJ's filing publicly available?

sciuruson Excel warriors who save governments and companies from spreadsheet errors

Dates can be weird just about anywhere.

I recently hit a bug where all data was being checked to see if it was a datetime, and python interpreted `st1` as September 1st of the current year.

sciuruson ElectronJS alternative: SciterJS – HTML/CSS/JS in 4.5 MB executable

If they're still trying to fund open-sourcing it, what is in this repo?

sciuruson Waypoint: Build, deploy, and release applications across any platform

And yet terraform uses the same format and is the leader in its space?

sciuruson Model fits in a tweet and predicts all elections since 1960

29% chance, actually. Washington Post had a piece that mentioned this today.

"On Election Day that year, FiveThirtyEight’s forecast gave Trump a 29 percent chance of winning. This was a better likelihood than was reflected for Trump in a number of other forecasts, though it still amounted to just under a 1-in-3 chance he would win. The site’s Nate Silver wrote that there was a 1-in-10 chance that Trump would lose the popular vote and win an electoral college majority, which is of course what happened."

Can you tell us anything about the architecture?

sciuruson Universal Split Screen

It's the pi edition.

sciuruson The internet needs our love

Keep in mind that the current CEO has been in that role for less than a year. The previous CEO led Mozilla from 2014 through 2019.

sciuruson Ask HN: Who is hiring? (October 2020)

Mozilla | Director of SRE | Full Time | Remote | https://grnh.se/0bb758871us

Mozilla is hiring a Director of Site Reliability Engineering. This is a new position overseeing the team I'm on plus two other teams in a recently-consolidated SRE organization. Come help us make the services behind Firefox and more better! I'm happy to answer any questions I can, just email me at bpitts+whoshiring @ mozilla.com

sciuruson Universal Split Screen

FWIW my four year old has started exploring minecraft on a raspberry pi 4. It runs decently, and the pi is pretty cheap.

sciuruson A list of discontinued Mozilla products and services

> I'd like to include internal tools where possible, but I think the main obstacle is finding sufficient info...

But why? What's the purpose of a public website with a catchy domain that chronicles when internal-facing tools were killed (usually because they were replaced with something better)?

I understand the agenda behind Killed By Google, but right now your site just leaves me scratching my head.

(Disclaimer: I work for Mozilla on the ops team that ran many of these services)

This was not a Mozilla project.

sciuruson How to catch a spy that is using a numbers station – The KGB Experience

I'd guess the problem is if you spend a long time trying to pick a lock in an apartment building, it looks pretty suspicious.

sciuruson What happened to Firefox Send?

hgmo is a good starting place, but there is lots of code in other places that is either incorporated into a Firefox release or directly supports it.

sciuruson Update on Firefox Send and Firefox Notes

Keep in mind the YouTube work is from the foundation, and Send and Firefox are from the corporation.

sciuruson How I operated as a staff engineer at Heroku

This is my experience, too. For example, if I look at the title breakdown across the three SRE teams at my employer it's

Senior: 53%

Staff: 35%

Senior Staff: 12%

sciuruson Kubernetes: Make your services faster by removing CPU limits

How are the limits incorporated into scheduling? I assumed that was based on requests.

What does "scale atomically" even mean? How does removing limits relate to horizontal vs vertical? HPA is based on request utilization, not limits, afaik.

What's your take on the arguments against limits in the comment at https://news.ycombinator.com/item?id=24356073 ?

sciuruson Kubernetes: Make your services faster by removing CPU limits

No, you still have a CPU request, and the HPA is based on utilization of that.

Also, even without limits I believe CPU is prioritized based on the request. So if 1 pod requests 100 millicpu and another pod requests 200 millicpu, if they both try to use all the CPU on a node the one that requested 200 millicpu will use 2/3 of the CPU and the other will use 1/3.

sciuruson Kubernetes 1.19

And GKE stable is on 1.15.

Although you can't launch new clusters on it anymore, Google hasn't even forced clusters on 1.14 to update to a newer version yet.

sciuruson Firefox 80

> Firefox mobile was how old? Two years?

I think the old Firefox for Android (Fennec) has been around for at least 10 years, not 2.

sciuruson Sumo Logic S-1

> May I suggest you try out Scalyr?

No. Please stop.
