LaserToy··on Deployment Confidence in Era of AI Coding
100%, and we have all of those things. Canary acts as the last line of defence, and honestly, when Canary detects and rolls back, it is already an incident that is being auto-mitigated with a limited blast radius.

To reduce the potential blast radius, we are working on a cohort-based canary, which will allow us to validate against a minimal, stable subset of traffic with the desired properties.

LaserToy··on Tell HN: Azure outage
Azure portal still insists the issue is jsut with Console.

We had to bypass the Frontdoor

LaserToy··on Summary of the Amazon DynamoDB Service Disruption in US-East-1 Region
TLDR: A DNS automation bug removed all the IP addresses for the regional endpoints. The tooling that was supposed to help with recovery depends on the system it needed to recover. That’s a classic “we deleted prod” failure mode at AWS scale.

LaserToy··on Metaflow: Build, Manage and Deploy AI/ML Systems
Cloudkitchens use them as well: https://techblog.cloudkitchens.com/p/ml-infrastructure-doesn...

They call it a DREAM stack (Daft, Ray Engine or Ray and Poetry, Argo and Metaflow)

LaserToy··on ML Infrastructure Doesn't Have to Suck
Same folks presented DREAM stack and some use cases at Ray Summit last year: https://www.youtube.com/watch?v=zaaKT0IyutQ. and https://www.youtube.com/watch?v=McjH0WfdAyI
LaserToy··on Thinking in Actors – Challenging your software modelling to be simpler
I love actors as a concept and I heard some large companies (Expedia) implemented large parts using them.

But I also saw how hard it is to understand a large system that built using actors. It is just hard to comprehend all the communication pathways and what happens in the system.

LaserToy··on Unfortunate things about performance reviews (2021)
Can anyone talk about a better model?

Some things to consider: 1) The company needs a way to weed out folks who are net negative. In general, if someone is not playing their part, there should be a mechanism to evict if up-leveling fails. 2) The company needs a way to distribute incentives (bonuses) as fairly as possible.

LaserToy··on Working from home is powering productivity
Exactly. So, we need to make those companies more successful:)

Was trying to gauge whether you are underpaid because you only accept remote work.

Economy will be the one that will determines the ultimate outcome, especially for tech companies, as they compete globally

How much are you paid? Total comp?

Companies need to make money. High performers will go to companies that make tons of money, even if relo to Sahara is needed
LaserToy··on Nuance: Preventing Schema Migrations from Causing Outages
It's a cool way to avoid painful database-related outages. I've never heard of DataLog before, and it seems nice.

Also, City Storage Systems is known as CloudKitchens — a new startup of ex-Uber CEO Travis Kalanick.

LaserToy··on It is hard to recommend Google Cloud
Try Azure. I thought AWS was bad till I faced GCP support and some weirdness. I thought GCP was not great till I faced Azure.
LaserToy··on CockroachDB license change
That is very interesting. As CRDB user, I priced Spanner (had to do some estimates during load testing), and Spanner came 3 times more expensive includign our eng salary to run CRDB
LaserToy··on Every map of China is wrong
Fascinating. How does streets align on the Chinese maps though? If random offsets are added, nothing should align. Or 500 meters is not large enough offset to create a mess? What I mean, arrears that are parallel in reality, may not be parallel on a map.
LaserToy··on Moving Millions of Orders with Robotic Conveyance
I think the same company published this: https://www.lab37.us/hello-world/blog as it mentioned CloudKitchens as well.

Which is another robot for food production.

LaserToy··on How much garden you would need to survive on
I did some math. Assuming a human male needs around 3000 KCal per day, it sums up to around 1,095,000 KCal per year. Potato is one of the most calory dense, as 1 acre produces 17.8 M KCal (found online).

So, one person will need 1 Acre (43560 sq feet) / (17.8 / 1.095) = 2679.6741573 sq feet of potatoes. Which will be 248.8872 sq meters (10 by 20 meters field).

It is either my math is wrong, or article is wron by order of magnitude

LaserToy··on How much garden you would need to survive on
I’m no farmer, but 200 square feet feels way too small. Really?
LaserToy··on How to beat the CAP theorem (2011)
Good OLAP needs very similar properties as OLTP, they just don’t as it is extra hard
LaserToy··on Every software project is a startup that will probably fail
I love the topic. My view on the companies: they are similar to countries in terms of organizational complexity. And the way companies are run are similar to the way countries are govern. Mostly due to the fact that there are not that many ways to manage groups of people or individuals.

So, I’m not surprised the observation about startups also applies

LaserToy··on KPIs for Software Engineers
Having that many KPI makes them useless. Also, lines of code written?

One day, put all of them in PCA or tree model, and compare to your own observations on who is the most valuable eng in the org

LaserToy··on You're neither in control nor responsible for their failures
Managers are responsible for project failures, that is true.

And they have a mechanism of achieving it: hiring and firing.

The author is right, managers are not responsible for individual’s success, their ability to persevere, time manage and so on. We work with adults, they have their parts to do.

LaserToy··on I was banned because of a security flaw in Facebook’s password recovery system
Looks like you are in us. Drag them into small court by claiming $9999 in damages. They will have to send a human or pay. I guess if they just pay, you can do it per product.

Class action might be possible as well

LaserToy··on Why is remote work seen as a gift?
In US, it is relatively easy to commit fraud. The question is: what happens if you get caught. Is it a slap on your wrist or a catastrophically failure (termination, prison time)

You can, for example, get employed at 10 companies and then outsource all the work (someone got caught doing it and it was in the news).

If you want to cheat, you can, but you probably should not be discussing it on hacker news.

LaserToy··on Excess management is costing the U.S. $3T per year (2016)
Every control/alignment system has overhead. That is exactly why distributes systems are both hard and slow, just look and Spanner/Cockroach and compare them so single node PSQL.

To get rid of managers, you will need to solve comms problem.

LaserToy··on Tell HN: Crypto/web3 grifters are Now AI/ML grifters
Opportunists?

I worked on ML/AI, I call AI: artificial idiot…

LaserToy··on Distributor cancelled an order and we need to move 30k bags of coffee [updated]
Uff, was able to get decaf and hopefully make a new year a bit more tolerable!

Happy New Years!

LaserToy··on The more metrics you track, the less you know
There are many, like GDP for countries. Temperature for your body. Etc.

They are not perfect, but without them it is virtually impossible to know what is going on.
