jaxn··on Show HN: Remove-bg – open-source remove background using WebGPU
I got pretty far down that path during Covid for a feature of my saas, but limited to specific product categories on solid-ish backgrounds. Like with a lot of things, it’s easy to get good, and takes forever to get great.
jaxn··on Vision Pro: What we got wrong at Oculus that Apple got right
I don't think VR is all that different from smartphones at the time of the iPhone launch. The Quest has sold over 20 million units. And at the time of the iPhone launch, a lot of people still had "camera phones" and "feature phones". Business users (like me) has Blackberry / Treo / or a few Windows devices. There were weird texting phones for teens that had keyboards, etc. But most people did not have a smartphone.

Thank you and damn you. I’m sold.
jaxn··on Vision Pro: What we got wrong at Oculus that Apple got right
The first iPhone was a toy. It wasn’t until the second version (iPhone 3G) + AppStore that is really caught on with existing smartphone users.

I have a Quest and have used other VR systems, the Vision Pro felt like a huge leap forward compared to those.

I walked away from the demo tempted. Not by what is available today, but by what I want to be available and what I want to create with it.

Power is also a concern (at least for sailboats). While there are certainly other 12v computers, that is one of the pluses for rPi in this.
jaxn··on MacPad: I created the hybrid Mac-iPad laptop and tablet that Apple won't make
So, a modern Apple IIe?

I used a Comodore 64 plugged into a black and white TV as a kid. This would be the same kind of thing. Sure, an iPad could be the monitor, but so could your TV, or an actual monitor. A computer with storage and input device as a single unit, but without a monitor.

That is quite different from an iPad with detachable keyboard, or even a Microsoft Surface Book (which had auxiliary computing in the keyboard / base, but the CPU and storage was with the display.

I like it. Seems like a great idea to me.

jaxn··on Blazer: Business intelligence made simple
That guy maintains a shocking number of projects. Pghero, Ahoy, a ton of useful Ruby data / ml libraries.
jaxn··on Show HN: OpenStatus – Open-source monitoring with incident managements
Ah, under Services, not Open Source.
jaxn··on Show HN: OpenStatus – Open-source monitoring with incident managements
I had just been looking at open source status pages this morning, and this was not in the list I was looking at.

OP, you might want to d a PR here: https://github.com/ivbeg/awesome-status-pages

Everyone else might be interested in that list of similar projects.

jaxn··on The Ashley Book of Knots (1944)
Knots end up being the weakest part of the line. Whenever possible I prefer splices when heavy loads are involved.
jaxn··on Microsoft Docker Development Container Templates
I love devcontainers, I just wish performance was better on Apple M* chips.

Granted, it’s not really a problem with devcontainers as much as it is with docker mounts. But that makes devcontainers terribly slow when the code is on the local file system and mounted into the devcontainer, which is the default.

jaxn··on Github.com is down
except for the people maintaining us-east-1
jaxn··on Codespaces but open-source, client-only, and unopinionated
I also don't see how this is different from devcontainers, which are like codespaces, but without it being hosted on a server.
jaxn··on Alphabet selling Google Domains assets to Squarespace
I’m on Azure, it’s still Microsoft. I like a lot of Microsoft stuff these days that plays nice with open source dev tools. Azure doesn’t get in the way of that, but my defaults are not their defaults.

I’m perfectly happy with AKS. Their Postgres product is great (formerly citus). But at the the end of the day, they still want to sell Windows, Exchange, SQL Server, Active Directory, etc. That’s a choice I will probably never make, so it just feels like a mismatch.

jaxn··on A few words on Ruby's type annotations state
In Ruby, I would see your example as name having the value str. Chomp would have the value of the result of the operation assigning bool the value of False, which I result of the operation might be true, so would chomp have the value of true? Either way, it looks like an assignment instead of comparison error, so I’d kick it back in a PR no matter how it worked.
jaxn··on Evidence.dev – Business Intelligence as Code
Thank you for building this! I am really excited to try it out on a backlog item this week.

It seems like you really nailed a sweet spot. Analyst first reports as a product that can be extended / enhanced by devs, and both can continue to maintain the project once it ships.

jaxn··on Launch HN: OutSail (YC W23) – Wingsails to reduce cargo ship fuel consumption
When sails provide lift, that is forward motion, not vertical.
jaxn··on Launch HN: OutSail (YC W23) – Wingsails to reduce cargo ship fuel consumption
Or maybe some sailing experience. It didn’t sound to me that they are active sailors.

Will there be a keel or any other foils to help create lift to not just get blown sideways?

To me this seems like solar roofs on electric cars. An obviously good idea that doesn’t really have a meaningful benefit.

I also thought it sounded more like a j/24 cockpit locker.
jaxn··on Reversing into a car park safer, more efficient for driver and pedestrians
Valets park cars all day long. And they back in.

When you are parking, you have much more visibility of oncoming traffic, and the other drivers see you more clearly too. When backing out, you have less visibility and are less visible.

It’s a terrible article. But backing in is absolutely the safer option.

jaxn··on Tesla tells investors it’s being investigated by the Justice Department
I placed my order on AI day in 2019 right after all of the claims were made. I took delivery June 1, 2019.

When I ordered the car, I did so expecting it to be able to drive while I slept sometime during the life of the car. I have considered suing Tesla for failing to live up to the promises that prompted me to purchase the car. I had never purchased a new car before and wouldn't have except for the phantasmal claims of full-self driving. Refunding the $6k I paid for FSD seems insufficient to me.

jaxn··on FCC threatens to disconnect Twilio for illegal robocalls
I reply to the ones wanting to buy houses that I don’t own. I drag them along for days. I figure I can at least waste their time
jaxn··on The Real Book
I will never forget buying my Real Book in the early 90s. I bought it from Cotton Music in Nashville.

They pulled it out from behind the counter in a paper bag. 14 year old me felt so cool, like I was joining a secret club.

jaxn··on Companies use drip pricing to overcharge consumers
I suspect most people tip on the after-tax amount when they calculate it themselves. I get that you don’t. I also know people who tip on the non-alcohol amount. Personally, I have always tipped post-tax.

These are also low-margin businesses. A post-tax surcharge keeps your overall bill lower than if they had raised prices, which would also raise the tax amount. The high labor costs are going to be passed on to consumers regardless. The surcharge shorts the government (which most of us are probably fine with).

Caching. There are multiple layers of caching in rails, including caching of rendered views/partials.
jaxn··on Ask HN: Why are big tech companies having mass layoffs?
It’s not just that they staffed up, but also that it was really hard to hire since everyone was hiring. So salaries went up, and internal recruiting teams expanded to meet the hiring need.

When the hiring slowed, there was not as must work to do hiring and onboarding new employees. This is why so many companies are including “HR” in their layoffs.

The other piece is even if they didn’t over-hire, they over-paid. I believe these mass layoffs are a natural way for salaries to go back down to pre-pandemic-ish levels.

jaxn··on Show HN: Retool Mobile
Damn that is good customer service. I like how y’all do things at Retool.
jaxn··on The ThinkPad TrackPoint tried to build a better mouse (2020)
I have a Tex Shinobi and the Lenovo trackpoint keyboard. The Tex is on my Linux workstation at the office.

When I had a Thinkpad and used the Trackpoint keyboard with my workstation, I had the same muscle memory for both. Bought a MacBook for battery life.

jaxn··on The ThinkPad TrackPoint tried to build a better mouse (2020)
I would easily pay 20% more for a MacBook with a TrackPoint.
