davidbanham··on Ask HN: How can I start a business to generate electricity?
In Australia we have a large amount of rooftop solar. We used to fit isolation switches near the panels on the roofs so that we could de-energise as much wiring as possible in the case of a fire.

The stats showed that the rooftop isolation switches shorting out was the leading cause of fires. We no longer fit them.

davidbanham··on Apple tells employees to work at the office three times per week starting Sept
Working from home requires some planning and modification in order to make it work. Sitting at a laptop in the same room as your kids has a predictable outcome.

The specific changes required are different for everyone. Things like a separate room with a solid door, though, are a good start when you share a home with other people. Teaching your kids what it means when the door is closed versus open can really help too. Same with whomever is caring for the kids while you work, setting clear expectations up front is a great start.

The H in WFH doesn’t necessarily have to mean your house, either. Maybe it’s a local coworking space. Maybe it’s a nearby friend’s house. A coffee shop, a hammock in the garden, a local park. Whatever works for _you_.

The key, though, is that you have to figure all that stuff out on your own. There’s no facilities team serving you a one size fits all solution. It’s more work. The benefit is that you get something tailor made.

I like the concept, but the lack of a great mobile interface (either responsive web or app) is a real deal breaker. Signed up for the trial but will cancel, would love to hear from you again once the mobile side is ready to go.

Yeah totally! That’s a path that regulators often take rather than banning something. It’s all part of the same root as I see it. Removing non-obvious dangers or turning them into obvious ones.

You’d still need to satisfy the requirement that they don’t pose a threat to non-occupants though. Pedestrian and bystander safety is a thing. Might be taken care of by limiting the max speed.

Haha yeah I’m definitely out of my depth on the actual application of the specific formula here. Thanks for the correction!

You seem quite worked up, and seem to be having a discussion about how a motorcycle would perform in a collision with a large car versus a small car colliding with a large car. To be clear, that's not what I'm talking about here. I was picking up on the parent post's question about why a motorcycle should be road legal, and this thing not, when the collision danger was probably equivalent or higher.

I'm not saying that this car is more dangerous in a collision than a motorcycle. It might be, though. This weighs more than a motorcycle, which means more mass involved in the collision, which means energy to be dissipated. In a basic understanding of physics, this is sometimes referred to as the mass-energy equivalence. It's denoted by the formula E = mc2 which is fairly well known.

It's not just about mass though, is it? It's not even just about collision safety.

Cars have features like airbags, crush zones and impact protection cells to make collisions more survivable. Some of these features are optional, but many are mandated by governments on new cars.

One of the reasons this vehicle would not be road legal is because a passenger getting in to the vehicle, or someone buying it second hand, would reasonably expect it to have these features. This is what I mean by obvious and non-obvious dangers. A motorcycle has obvious dangers. It's clear to anyone that if a car t-bones you, that car will impact your body directly. This car, however, has the appearance of "a newish car". What that means to someone in a developed country like Australia is "a vehicle that meets basic safety standards". This vehicle contravenes that expectation in a non-obvious way.

Regulations also exist around things like handling dynamics in collision avoidance scenarios. How does this vehicle perform if you need to swerve suddenly to avoid a kid that has run out in the street? Will it turn or skid onwards? Will it roll over? Will something else happen? It might perform wonderfully, but the certifying authority doesn't have any reliable information that someone reliable has tested it.

New vehicles sold also have regulations around the reliability of individual components. The master cylinder for the braking system must be manufactured to a given standard of quality. If the plastic casting is crappy and the lid blows off when you hit the brakes, that's a bad thing and someone could be hurt. Preventing things like this happening to unsuspecting bystanders is why we live in a society that has agreed to place restrictions upon itself for the greater good.

davidbanham··on Unboxing a $100 Chromebook
I've had that "I should just use my laptop" moment many, many times. There are lots of things the iPad is objectively worse at than my very nice X1 Carbon running Arch. And yet I keep coming back to my iPad pro. I can't put my finger on what it is but I think it's some combination of:

1. Gorgeous high resolution, high refresh rate, generally pretty screen.

2. Long battery life.

3. Instant wake.

4. Ruggedness. Even with solid-state everything I'm always a little wary of chucking my laptop into the passenger seat of a car, taking it near sand or dust, etc. There's fan vents and hinges and... stuff. The iPad Pro in a Logitech Folio case has all the corners protected from drops, no airflow, few holes. I just don't worry about it.

5. Pencil. The handwritten notes experience has gotten really good. Being able to flick into that mode any time is nice.

I really like the Logitech Slim Folio case with a separate small bluetooth mouse for when I need it. 98% of the time the trackpad would just be taking up space that I'd rather fill with keyboard. The times I do need a mouse, I probably want a proper mouse rather than a trackpad.

The different remote desktop apps (VNC, Nomachine, etc) have ways to translate touch events into mouse pointer movements/clicks. Not what you'd want to use for a serious CAD session, but fine for little things here and there to save pulling out the mouse.

They give you the new app for free if you paid for the old one now. Not sure if that's something they added later on but it's a thing now.

A motorcycle has obvious dangers. An unsafe car has non-obvious dangers.

A lot of government regulation is about preventing non-obvious dangers or trying to make them obvious.

I use Blink to mosh in to a server where I do my work through tmux, vim, etc.

I use Safari to view the stuff I’m building. There’s a Safari dev tools plugin which sucks compared to Firefox dev tools but it’s okay in a pinch.

I use NoMachine to remote into the graphical desktop environment of the server on the rare occasion I need to use a real browser.

My understanding is that the items have different uuids, but there are no markings on the physical item. They’re identified by bin location.

There are lots of bins in the warehouse. They contain up to around five items each. There is a theoretical possibility that two of the same thing from different sellers could end up in the same bin. At that point the picker wouldn’t know which is which.

Just pointing out that your data has a pretty clear confounder. “Wfh” and “wfh during the initial stages of a global pandemic” are very different things.
davidbanham··on Ask HN: How did you overcome perfectionism?
Ship. Get feedback. Then do it again. Now some more times.

Perfectionism occurs due to a lack of information. You don’t know what “good enough” is so you err on the safe side. The more you put something in front of people and then talk to them about what they think the better calibrated you’ll be.

davidbanham··on The Rain System “contains wildfires within 10 minutes of ignition”
You’re referring to a canopy or crown fire. It depends on conditions, of course, but it usually takes time for enough heat to build up that a fire crowns. There’s generally a period where it will burn through the lower and mid stories and it spreads.
davidbanham··on Ask HN: What's the best way to monetize actual programming?
It’s very difficult to get paid a multiple of your colleagues in the same role even if you’re multiples more effective. It’s more possible to command a high day rate as a consultant, so long as you can give people confidence you’re able to deliver.

Another option is fixed price, fixed scope builds. You price in line with the rest of the market, then build it fast and pocket the profit.

Both of these, however, require a lot of work that is Not Programming. You’ll need do some sales, some client management, some project management, etc. That’s the gig, but these things can be fun too.

The big factor is that you’ll be 100% exposed as to whether the high volume of code you’re putting out is all truly effective. Your clients on the above kinds of projects don’t care how much code you wrote and they may never see your PRs. They care if their thing does what they wanted it to do. You have to deliver value, not just code. That can be exhilarating, just make sure you’re ready for it.

davidbanham··on Ask HN: Should I give my employer all my medical records?
I would not sign that agreement. I suggest you speak to the Fair Work Ombudsman, who is the agency that exists to help you with these kinds of matters in Australia.

davidbanham··on Ask HN: Does Anyone else working in a crypto company feel this is all a scam?
I have a job satisfaction indicator I like to call “the barbecue factor”.

You’re at a social event with friends and friends of friends. Someone asks “so what do you do?” and you answer.

They either go “huh?”, “ooh neat!” or “oh, gee, yeah isn’t it awful how $industry is $negative_outcome?”

Which of those answers you get can have a big bearing on your job satisfaction.

It feels like the opinions of others shouldn’t be such a big deal. It turns out they are a pretty big deal for me, though. It sounds like it might be the same for you, and I suspect it’s the same for most humans. We’re tribal animals.

Once I figured that out, I started factoring it into my career decisions. I’ve been much happier for it.

Also, it’s just not that hard to “undo” a nailed framing joint. Bang the top piece of wood with a hammer from the underside. It will separate from the other piece with the nails still in it. Now bang the nails out by hitting the pointy bit with your hammer. Job done. 45 seconds of work, just need to be comfortable on the tools.
davidbanham··on “It's not peaches and cream either for men”
Being tough and self reliant is great. Those qualities are not abrogated in the slightest by being able to talk with others about your internal experience. You can help yourself by doing so and also help those around you in the process.

The goal is not to be immune to stress and trauma. That’s not really a thing. The goal is to be able to deal effectively with adversity and overcome it. Part of being able to do that is acknowledging that you’re not a robot and employing appropriate strategies. Discussing these things with people that share common ground with you is an effective release mechanism. Releasing pressure during downtime enables mental toughness and self reliance in critical moments.

davidbanham··on Thousands of Australians are living with undiagnosed cancers after lockdowns
There were periods where the strong advice was to just wait a minute for non-urgent GP visits and general checkups. Also elective and non-urgent surgeries and day procedures have been suspended in hospitals a few times, either to manage infection risk or staffing shortages.

More than the actual closures though I think there’s been a perception in the public that it’s better to wait a bit. Vaccination rate is now 80% nation wide and over 90% here in Sydney so we’re up and running again.
