lflux··on Coyotes are being seen on the empty streets of San Francisco
I've seen a coyote dart across the street in SoMa in the middle of rush hour. Nature's a bit closer than we think.
lflux··on Secor: A service persisting Kafka logs to S3, GCS and Azure Blob Storage
Good question. Kafka is cheaper for things that don't need to go into redshift, and there's a fair amount of engineering effort that would go in to switching those existing systems over.
lflux··on Secor: A service persisting Kafka logs to S3, GCS and Azure Blob Storage
We've phased out Kafka for the parts that feed Redshift, since Kinesis Firehose is a far better experience. We still have Kafka for our application logs and performance monitoring

Kinesis Firehose doesn't read from Kafka, we switched our code to publish to Kinesis instead.

lflux··on Secor: A service persisting Kafka logs to S3, GCS and Azure Blob Storage
We've used this at Patreon to get data from our various sources in the application to Redshift. We've since replaced this with Kinesis Firehose
lflux··on Google's Internal AGPL Policy
Same thing inside Amazon. GPLv2 on a case-by-base basis, AGPL/GPLv3: don't even ask. BSD/MIT: Go hog wild

What about Greenplum or CitusDB?

That's my takeaway as well.

Holy shit, that's my college prof from KTH who taught us Intro CS

>(b) the one with the newest and safest roads.

Yeah that doesn't describe 101 around SFO one bit.

lflux··on So You Think You Want to Open a Brewery (2014)
It’s not uncommon for craft brewers to contract out the brewing of bigger runs. Evil Twin (and I think his brother, Mikkeller as well) was exclusively a “phantom brewer” who developed recipes and then had other breweries brew them on contract. Sometimes it’s bigger established breweries that do a few batches on contract for them, but there’s also explicit contract breweries like De Proefbrouwerij
lflux··on Parts of AWS are down
From the phonecall with our AWS TAM and support reps
lflux··on Parts of AWS are down
DDos against amazon's DNS servers. One mitigation is to use regional endpoints for bucket hosting if your website relies on serving assets - i e foo-bucket.s3.us-west-2.amazonaws.com instead foo-bucket.s3.amazonaws.com
lflux··on AWS Elasticsearch: a fundamentally-flawed offering
Migrating to a different hosting platform than AWS for ES aslo mitigates this problem too, which is more likely in our case.
lflux··on AWS Elasticsearch: a fundamentally-flawed offering
1. We changed a configuration parameter, which we thought would be a no-op but caused a deploy

2. We ran a fairly large cluster with a large amount of i3.xlarge

3. One AZ in us-west-1 didn't have enough capacity of that SKU . The other AZ did, but this doesn't help if you have a multi-AZ deployment.

4. We switched to EBS-based instances after this

lflux··on AWS Elasticsearch: a fundamentally-flawed offering
That's exactly what we told our TAM, SA and the AWS ES PM cc'd on that thread.
lflux··on AWS Elasticsearch: a fundamentally-flawed offering
Agreed, this article captures my experience accurately as well.
lflux··on AWS Elasticsearch: a fundamentally-flawed offering
Heaven forbid you make a configuration change that triggers a blue-green deployment and during the deploy one of the AZs runs out of that instance SKU. Your deployment has halted until you can get ahold of AWS support to get them to unstick it (this takes a couple days even with enterprise support). There's no way to know if the AZ has capacity or not, it's something you find out in the deploy.

The workaround AWS support proposed was to reserve 2x capacity so we wouldn't run into this issue on subsequent deploys.

lflux··on Richard Stallman challenges 'misleading' coverage of his comments on Minsky
From https://medium.com/@selamie/remove-richard-stallman-fec6ec21..., stallman is quoted saying

> “I disagree with some of what the article says about Epstein. Epstein is not, apparently, a pedophile, since the people he raped seem to have all been postpuberal.” He preferred to call Epstein a “serial rapist.”

yeeeeeesh

lflux··on Detroit News Vehicle of the Year is a Tesla
Right - I knew exactly what I wanted since I had driven the car as a rental.
lflux··on Detroit News Vehicle of the Year is a Tesla
Sure, if the quote is out the door, but it never seems to be from what I've seen.

This was "Here's the price excluding title transfer including delivery"

lflux··on Detroit News Vehicle of the Year is a Tesla
A bunch in the bay area. I use San Francisco Federal, but they use PatelCo CU's service.
lflux··on Detroit News Vehicle of the Year is a Tesla
I emailed a bunch of dealers before my CU told me this service existed and got quotes, and they were competitive. It differed like, $500-1000 from what area dealers were offering and i was willing to take it.

So, some legwork with a throwaway email address, but still very sofa compatibile.

lflux··on Detroit News Vehicle of the Year is a Tesla
I had my credit union's car purchasing department handle my car purchase. Did everything over email - I told them what I wanted and in what color, they did the legwork to find a dealer that had what I wanted. Emailed me a quote, then the dealer delivered it to my door.

No haggling, no visiting dealers, just email and signing some papers.

lflux··on ‘The Trains Are Slower Because They Slowed the Trains Down’
Stockholm metro has this as well but I wouldn't call it "autonomous", it's just a departure button to get the train moving faster. The driver still has to grip the vigilance device after a certain amount of time.

According to https://en.wikipedia.org/wiki/Vienna_U-Bahn#Fifth_expansion_... it seems that vienna isn't driverless yet.

lflux··on ‘The Trains Are Slower Because They Slowed the Trains Down’
Nothing. Hong Kong, Singapore, London, Paris, Copenhagen as well all have lines that run in driverless mode. Heck, even SF Muni runs in autonomous mode in the subway, it's only run in manual mode on the streets.
lflux··on One year of cycling to work
Only other city I've ridden is Stockholm, and I commute on Folsom which has a striped lane but basically:

a) Make sure you're visible. I always have lights and reflectors, and wear hi-vis jacket if it's dark out

b) Always assume there's an Uber about to do something dumb and dangerous - ride defensively, don't assume that drivers see you, seek eye contact, don't be afraid to take the lane

c) Relax, take it easy, it's a wonderful city to ride in.

lflux··on One year of cycling to work
I've been biking to work every day for over 6 months now, though mine is considerably shorter - 2 miles in SF. I got tired of being stuck on cramped muni trains not going anywhere and figured I could use a little exercise every day.
lflux··on Airbus Handed A380 Lifeline With $16B Emirates Order
The first ones off the production run aren't as fuel-efficient as the later ones. I read somewhere the first few A380s are several tons heavier than further down the line.
