stevejb··on Show HN: Create a portrait painting from one photo
I think I generally agree with this take, with the caveat that I still hugely value AI generated art, even the kitsch stuff. Why? Because it's me. I wouldn't have been able to have a portrait of my wife and I together without finding an artist and commissioning a painting. Now, I can have something that is personalized, pleasant to look at, and meaningful. Even if it isn't an original style or anything noteworthy artistically, I hugely value the AI art because it can give me something that I want, that is meaningful to me.
stevejb··on Ask HN: What was your most humbling learning moment?
Why this comment? This was a really interesting anecdote about how complicated situations in life can be.
stevejb··on Parsing JSON Is a Minefield (2018)
I definitely agree with a lot of the comments here especially the ones in the vein of “don’t do dangerous things with json. “ if you have control of the sender and the receiver, it makes sense to have fields that add a bit of extra type information e.g. this is an integer or this is a float with this much precision
stevejb··on EPA bans asbestos, a deadly carcinogen still in use decades after partial ban
I don't understand. Are you saying it is good that people are teetotalers and that is an example of doing your best?
stevejb··on EPA bans asbestos, a deadly carcinogen still in use decades after partial ban
I was visiting a relative in their $3M+ house in Bronte and saw plenty of it. Not in the front facades of the homes, but drive through the back alleys, and you can spot some in < 1 min. I remember an uncle there who's neighbor had a fibro cement mail box which was built into some stone work.

I agree my usage of "plenty" was more in absolute terms. It is probably thousands to tens of thousands, which is small in percentage terms. I also spent a lot of time on Australian farms, and they have lots of asbestos sheets buried in places. Most farmers would rather pile it up or bury it then pay the costs of having it removed properly.

stevejb··on EPA bans asbestos, a deadly carcinogen still in use decades after partial ban
Probably not. They’ll understand it was the best we could do at the time, just like we understand that about our ancestors.

Australia also probably has some of the worst deployments of asbestos in the developed world. Drive around even nice neighborhoods in Sydney and you’ll see plenty of cracking and breaking “fibro”, a cement asbestos sheet. Canberra is full of asbestos. They had to completely remove an asbestos mining town (Wittenoom) from the map because it was so contaminated.

There is a ton of asbestos currently in Australian households. Plenty of aussies drink water collected in tanks off of asbestos cement roofs.

stevejb··on Cutting down AWS cost by $150k per year simply by shutting things off
I work for a company called CloudFix, and we are solely focused on AWS costs. We do automated AWS cost optimization. We find one of two reactions when we deliver savings to customers:

(A) "Hey wow, this is great! We are so excited to be saving from here on out." OR, (B) "This should have been caught earlier. $TEAM was supposed to be experts..." and then blame game starts.

It is really unfortunate when institutions react in the latter way. Often the engineers are assigned to cost optimization, along with a million other things. And, the incentives aren't really aligned well to reward savings. For example, S3 Intelligent Tiering is the right thing in 99.9% of cases - so it should be your default bucket type. BUT, engineers often face only downside risk for the change, and very little upside reward. And, it isn't their money so they just leave it. The cost of overprovisioned S3 can be staggering!

What is really needed is to establish a proper FinOps discipline, put someone in charge of cost savings, and make sure incentives are aligned properly. And of course check out CloudFix if you can!

stevejb··on Linux 6.2: The first mainstream Linux kernel for Apple M1 chips arrives
I think it's like saying if you learn how to maintain a submarine, have you become a good swimmer? Or, if you know how to maintain a submarine do you understand fluid mechanics?
stevejb··on Cameras on phones? (2001) [video]
I just watched this video on a plane, going nearly 600mph at 33K ft above northern Canada. The pace of technological evolution I have experienced in my lifetime is absolutely miraculous.
stevejb··on LG 28-inch 16:18 DualUp Monitor
What 43" monitor are you using? Do you happen to have a picture of your setup?
stevejb··on In defence of garlic in a jar
I've had many pourovers and I appreciate them if I have the time. If I like pour overs at value P, then I would rate an instant coffee at 0.9P. The 0.1P of value I miss out on isn't worth the hassle of filters, dealing with coffee grounds, all that stuff.
stevejb··on Math on GitHub: Following Up
It may be worth looking at org-mode syntax. Yes, org-mode is part of Emacs, but the syntax of the file seems to meet some of your requirements, namely parseable by human and machine alike.
stevejb··on Pedal Me bans staff riders from wearing helmets for safety reasons
I used to live next to a popular bike trail, that had 0 sharing with cars. Not a road within 50 meters. There were plenty of injuries. Bike vs bike, bike vs pedestrian, bike vs stationary object, distracted cyclist injures themselves. Etc. If you're going 30 km/hr in thin lycra, you can certainly injure yourself with no help from anyone or anything else.
stevejb··on Why companies move off Heroku (besides the cost)
Preface: I work for DevGraph, which contains EngineYard.

I would definitely have a strong look at EngineYard [1]. Our tagline: "A NoOps PaaS for deploying and managing applications on AWS backed with a world-class support offering." There is a good comparison with Heroku located here [2].

Having worked with several engineers, I can personally vouch for the world class support. We spend a lot of time thinking about and implementing ways to host Ruby, Node, PHP, Java, Python, and other containerized workloads on AWS. EngineYard has been around since before Heroku, so we have a long track record and a lot of experience in making your applications run reliably, keeping costs under control, and with full 24x7 support.

Email is in the description, along with my Twitter. Please reach out for any questions.

stevejb··on The Rise and Rise of Corrugated Iron
I live in rural Australia. Corrugated iron is everywhere, and I love it. It is durable, lasts a really long time, is easy to repurpose. I know an older gentleman here who built a really nice barn out of some repurposed corrugated iron roofing. I'm about to build a shed for a home office, and will use corrugated iron. It is cheap, easy to work with, comes in decent colors (e.g. the ColorBond brand in Australia), is strong without being overengineered. It's great stuff.
stevejb··on My parents collect cans for a living
There is also less alumnium in a can now than from the 70's, so it may not be as bad as is apparent.
stevejb··on Tell HN: Azure is having a major outage
Same as when horse and buggies will come back in response to a disruption of the gasoline supply chain.
stevejb··on The popularity of e-bikes isn’t slowing down
Not sure why you're downvoted on this. I used to live near a very popular mixed-use bike trail, and walking with my kids there was really unpleasant. There were some cyclists who would go really fast and not slow down at all, and I had little kids who might see a butterfly and move unpredictably. It was bad for everyone.
stevejb··on Thoughts of work invaded my life until I learned how to unplug
Something you can take from Judaism is the concept of Shabbat where you can take 1 day a week to devote to family, study (that isn't related to your job), personal things, host a dinner with some friend (COVID permitting, of course). Clearly you don't have to be religious to do this, but you can take a dogmatic approach (e.g. your Shabbat starts at a certain time and is not reschedulable, Slack and work email are off during this period, etc.). It seems to be a time honoured approach to maintaining some balance in life.
stevejb··on A Victoria man has gone two decades without money
The good lesson it can teach is that there are hypocrites in the world, and that at the present time there is enough excess productivity in the system that people who contribute nothing can basically ride for free, and the value they contribute is that they serve as props for a fantasy discussion that is delusional at best.
stevejb··on A Victoria man has gone two decades without money
Uh yeah this is totally wrong. Life has never been better for the vast majority of the world's population.

> simply rotation so everyone does the unwanted jobs. It's a fair system and people will do it.

I think that what would end up happening is that in even in a small group of people, it would naturally emerge that there are variations in quality, efficient, economies of scale, etc. Even in my immediate family, there are some menial jobs that my wife does 90-100% of and some menial jobs that I do 90-100% of. If we tried to make if 50-50 or have some type of rotation, we would both lose.

stevejb··on Introduction to open source private LTE and 5G networks
I have been thinking about how to do a deployment on a farm, using a private 5G network for some sensors and security cameras. I looked at LoraWann but it didn't have the bandwidth for cameras. Would something like this work?
stevejb··on Restaurant workers quit at record rate
Guilt trip? I have never felt this ever. I pay a tip proportional to the service. 10% bad, 15% average, 20-25% for very good.

As an American living in Australia, I really do miss tipping. I think that on average the restaurant service here is a lot lower. At most restaurants at the medium level (e.g. $25 hamburgers) you pay in advance, and then a waiter will bring the food to you when its ready. Do you need more water? Get it yourself... Ketchup, you have to ask but it won't be offered. The waiters don't care because they are making good money anyway. The only place you get American style service is at the very high end places.

stevejb··on The price of lithium-ion batteries has declined by 97% in the last three decades
I just bought a 12v 200ah battery for $2300 AUD. It could be done for less, but this was a premium model. Hopefully when I purchase a second one in a year or two, it will be a bit cheaper.
stevejb··on DDD Is Overrated
I thought "Diners, Drive-ins, and Dives"
stevejb··on Ask HN: What automation tools have you used to replace mundane activities?
Not OP, but I think that the idea is that if a notification makes it through the system, it has been filtered to be worthy of distraction. So, there isn't a cognitive cost to the user of "is the notification worth reading" since it has already been determined to be that way.
stevejb··on Who’s in charge at Amazon? Moves on secretive S Team signal giant’s priorities
Nobody but yourself has to give you permission for this. It's an honest living. Lots of people who would give you shit about this are in the VC-funded "Uber eats for dog treats" world and may have an over-inflated sense of the social value their jobs are supposedly creating.
stevejb··on The forgotten joy of soap
I'm in Australia, can you suggest a few brands?
