jonpurdy··on Reflections on E-Bikes
Also, the stats for cars show that speed increases cause deaths to go up non-linearly, so your chances of dying in an accident are way more than double at 100 vs 50 km/h.

I would assume the same about motorcycles and ebikes, but presumably the threshold would be lower due to lack of protection (motorcycle helmet and armour not as safe as a metal shell with airbags).

So I wonder where that curve starts to rise up on bicycles and ebikes considering they wear just a bicycle helmet and no armoured clothing usually.

(I loved riding ebikes in China (Kunshan) with wide protected lanes that were totally separate from traffic outside of city center (where speeds were low and congestion high, negating they need)).

jonpurdy··on Raspberry Pi Zero 2 W
I ordered one, then quickly cancelled because of the lack of pre-soldered header. Looking for a drop-in replacement for my Pi Zero WH due to time constraints (new baby).

I presume they didn't make the pre-soldered header available at launch due to high demand and the ongoing chip shortage. Much easier to produce one less complex package.

Despite having just 512MB RAM, I think it's perfect for the its common use cases. For me, the CPU increase will be helpful for getting it set up and installing software (especially if it needs to be compiled), not so much for when it's actually being used.

jonpurdy··on Hardened wood as a renewable alternative to steel and plastic
Curious about your opinion on bamboo products. I assume you're referring to modern bamboo desks, shelves, and other items that are made from Chinese bamboo and made in China. They typically slice the bamboo grass pieces into ~8 sections, then use planing machines to create planks※. These are then pressed and glued together to make products. These products are then shipped overseas using the same methods as other products.

If the glue used is either sustainable or they don't use very much of it, and the bamboo is grown locally, what makes it less sustainable than using wood? And certainly more less energy-intensive than steel.

※ I am not a woodworker, don't know terminology.

jonpurdy··on Benjamin Button Reviews The New MacBook Pro (2016)
I think that the new laptops are a huge deal for Apple. Some folks argue that we're celebrating them putting back ports that should have been there from the beginning. And that the keyboards should have never gotten so bad.

I see it as a celebration. It's essentially an acknowledgement that they were wrong about all that, and they've built a heavier and "uglier" machine that people actually want/need.

As SJ said, design is how it works. Dongletown + bad keyboards was a bad design, and now they're back to prioritizing usability.

jonpurdy··on Victorian gas lamps that sold cups of hot coffee (2012)
Having lived in Korea and visited Japan, ubiquitous vending machines is an absolute game-changer. Especially with a choice of hot or cold drinks, vending machines really make life super convenient.

Pretty cool to see the Victorians had this idea over a century ago.

jonpurdy··on Kape Now Owns ExpressVPN, CyberGhost, PIA, Zenmate, and VPN “Review” Sites
This is awesome. I'd love to see this exact setup applied things other than web hosts!
jonpurdy··on China’s noisy ‘dancing grannies’ silenced by device that disables speakers
Noticed this when I moved to SF a couple of years ago. No idea why it's so popular here compared to Toronto, especially when people are alone and can just wear earbuds.
jonpurdy··on How big tech runs tech projects and the curious absence of Scrum
Everyone is correct in this thread. The stimulation of discussion is useful, and numbers are arbitrary.

Instead of worrying about 5 vs 8 though, the team should be discussing relative difficulty: is story B easier/more difficult/complex than story A? And then ranking stories based on the relative difficulty of each other.

Story points can then be derived based on that ranking, if the team chooses. They're useful for being applied to velocity calculation, and also helpful when picking up a story to work on (maybe a bad idea to start an 8 pointer on a Friday).

(I have a SM cert, working as a TPM. I applying Agile principles to teams, but modified to how they want to work and be most effective. No militant Scrum here.)

Don’t forget Carracho, a Mac specific Hotline replacement.
jonpurdy··on Leaving the Apple ecosystem behind
No need to go on a limb, .dmg files are usually software installers. But if I'm paying for a backup service that claims to back everything up, I want them to do exactly that, regardless of whether it can be re-downloaded or not (which takes additional time, not to mention figuring out what was missing from the supposed "everything" backup in the first place).
jonpurdy··on Leaving the Apple ecosystem behind
If I had known about their filter list, I would've done exactly that. But their implication that everything was backed up from the beginning by default is what got me.

ISO files are included in that filter list, among other files like VMs and such. Seems like a massive exclusion net to cast when claiming everything is backed up.

jonpurdy··on Leaving the Apple ecosystem behind
I found out the hard way that Backblaze, despite their claims of "...automatically back up all your files including documents, photos, music, movies, and more. It’s that easy.", do not back up .dmg files (among others) by default. Which seems to be a huge omission considering the numerous use cases outside of just application installers.
jonpurdy··on So what is the deal with A/UX anyways?
For those interested, Shoebill※ is an emulator designed specifically to run A/UX and it’s works very well!

jonpurdy··on Man who unlocked nearly 2M AT&T phones gets 12 years in prison
I posted this and was wondering how this would affect AT&Ts business at all. If you’re carrier-locked or not, wouldn’t you still have a contract to pay and be on the hook for monthly fees? And if you don’t pay, be forwarded to collections?

(I’ve never had a carrier locked phone and never understood why people buy them.)

jonpurdy··on UK hotels adding service charge to room rate
One of the things I loved about living in Asia (and traveling to Europe) was all-in prices posted everywhere. Made it so much simpler to add up, and was great paying cash due to the even numbers and lack of change.

After moving back to Toronto (and now living in SF), my biggest beef at cafes and restaurants is with the Stripe/Square terminals that force the customer to decide whether to tip or not, requiring the user to interact with the screen. Just let me tap my phone/card and be done with it.

Raise prices 20% or do whatever you have to do so workers can be paid fairly. Don't make the purchasing UX worse by introducing decision fatigue or guilt.

jonpurdy··on Allbirds S-1 IPO
I ordered a couple of styles a few years ago. They seemed incredibly comfortable but both didn't fit properly due to the lack of half sizes so they were returned.

I guess it hasn't affected their valuation much though.

jonpurdy··on 1Password 8 will be subscription only and won’t support local vaults
I recently cancelled Evernote after 12 years of paying for it due to their new Electron client.

I've been using 1Password since 2008 and I'll be doing the same thing. I have tolerated the UI regressions and even subscription with version 7, but Electron is just unacceptable for what was once an amazing Mac app that put Apple's apps to shame.

jonpurdy··on Elementary OS 6 Odin
Long time Mac user (1992); I think the Mac UI peaked at Mavericks (some would argue Snow Leopard due to the dumb Save workflow in Lion). As soon as Yosemite started trying too hard to be minimal it started a descent into prioritizing style over UX. I haven't touched Big Sur yet and probably won't until I'm forced to with a new Mac.

Looking at screenshots of Elementary, it's so much more obvious how things work and what widgets do than on modern Mac OS. I've been running it in various VMs for a few years but didn't seriously consider switching to it full time until Big Sur was announced. I have too many paid-for Mac apps like Alfred, Keyboard Maestro, Hazel, Photo Mechanic, and others that prevent me from moving to Linux full time.

jonpurdy··on South Korea: The only middle power of its kind
1. I can see noise being an issue in Tokyo and Seoul because build quality isn't great and there's not much noise insulation. So you're heavily dependent on neighbours keeping quiet, and I was fortunate to have good ones. Funny enough, I've had far worse experiences with neighbours in both Toronto and SF despite better sound insulation.

2. I didn't mention commuting because I was referring to living locally within a neighbourhood where you don't have to leave. I didn't commute far (walked to work), and I couldn't imagine commuting with multiple line changes in either Seoul or Tokyo. It was bad enough in Toronto with just a 30 minute commute. (I won't commute ever again due to remote work so it's no longer a consideration for me.)

You're lucky to live in Europe, where the suburbs/non-downtown is much more livable and walkable than North America. In many ways, many European cities have the best of both worlds.

jonpurdy··on South Korea: The only middle power of its kind
I lived in Korea for years and have visited Japan as well.

Having lived in Toronto, South Korea (Ulsan), and now SF (Sunset), I can’t imagine a better place for a family to live than many neighbourhoods in Korea.

Now that I’ve got a wife, dog, and newborn baby, we needed to purchase a car to get them around (since SF public transit isn’t good enough for this). At least in Toronto we were within a few hundred metres of doctor/dentist/pharmacy, but lacked a walkable grocery store despite being in the city.

There are reasonably nice walkable streets, but in both Toronto and SF the neighbourhood streets are too wide, which results in traffic going way too fast along them. I’ve seen some traffic-calmed streets with artificial barriers and curves but there’s not much.

When I lived in Korea, both neighbourhoods I lived in contained everything I needed, and would have needed if I had a family at the time. And walking around (even with no sidewalks) was a pleasure because cars took the main roads. (Only the delivery scooters were a menace, which I’m sure you were familiar with ).

Of course, this excludes societal pressures, personal finances, etc that affect local Korean and Japanese people.

This is anecdotal, but I've been casually studying urban planning for years to help quantify why I found daily living in Korea to feel so much nicer than anywhere else.

jonpurdy··on South Korea: The only middle power of its kind
You are describing Seoul and Tokyo perfectly.

Despite having tens of millions of people and average densities much higher than most cities, they’re both among the most livable cities in the world.

Both of them inherited pre-war street layouts (in Tokyo’s case, despite being bombed, the layouts stayed the same). So neighbourhoods have narrow streets which makes them safer to walk (due to cars needing to drive slowly) and more interesting. And most neighbourhoods have older 2-4 storey or newer 10-20 storey apartments that provide the density to enable local shops and amazing public transit.

So much easier to raise children when you have everything you need within walking distance in the same neighbourhood, including child care.

jonpurdy··on Show HN: I built an app to create repeatable checklists to help with ADHD
Quick feedback: this is an interface paradigm that I haven't thought of before (and haven't stumbled upon, if it exists in other apps). Immediately recognized how useful it is and I've already set up a few checklists.

And the UI itself is simple and to the point without any BS (probably because you're independent and don't need to hit OKRs), and matches iOS so it was easy to jump into and get started.

Thanks and please continue development!

jonpurdy··on Show HN: I built an app to create repeatable checklists to help with ADHD
Typing one-handed since I have my 4-day-old newborn napping in my arms now as her mom gets some rest.

Even before having her, I have found it difficult to find a balance between high level to do lists (missing details), and more detailed checklists (that are harder to manage).

Keeping the simple repeatable stuff separate should make it easier to offload that cognition from my brain so I can focus on the stuff I NEED to think about.

Looking forward to trying it out!

jonpurdy··on Video tutorials now on PeerTube
I’ve briefly tried hosting with IPFS in the past and always found it to be super slow/not working at all.

If one has a super low traffic site and is already hosting themselves (whether on a home computer or VPS), what’s the benefit of IPFS? My understanding is that if a file isn’t popular, it’ll be served by your own IPFS node/pulled from your local web server, which seems redundant to me.

(I totally get the use case for popular files; it’s awesome for that!)

jonpurdy··on Canada weather: Dozens dead as heatwave shatters records
This works extremely well on a motorcycle at any speed above 20 km/h, even under protective gear (the only way I've tested). So well that I actually feel a bit cold at first when it's hot but not extreme (below 30°C).
jonpurdy··on A good livestreaming setup is a well-tailored suit
I wonder if using a polarizing filter over your webcam would reduce the glare from your glasses. Polarizing sunglasses very effectively reduce glare on water, as well as car windshields.
jonpurdy··on Ask HN: Have you found a good desk chair?
I considered the Aeron but the hard edge of the seat just didn't work for me.

Embody has a huge seat without any hard pieces and a back rest that narrows at elbow height. The first chair I've bought for myself and very expensive, but I love it and expect it to last a decade or more.

jonpurdy··on Note Taking in 2021
Evernote was very sticky for me since 2009, but started quickly looking for alternatives once the new app was Electron-based. I tried Bear a few years ago but didn't like it. Also tried Obsidian and a few others but they were too finicky for me. Finally tried DevonThink but it was overkill for my purpose, formatting was weird and different with all the note type variations, and their pricing model killed it for me (max two devices).

I basically needed something with great search, easy formatting, and inline image support. And I found it with Ulysses. I thought it was only for people writing long-form works, but it works fantastically for my use case. It ended up being the thing that replaced Evernote for me after 12 years.

jonpurdy··on Forget going back to the office – people are just quitting instead
From what I understand, it's an issue in Canada as well, but only if you leave money in the company and don't take it out as salary.

If you pay yourself 100% of the extra revenue (aside from expenses), then there's no avoidance of a lower corporate tax, thus no issue.

jonpurdy··on Software is eating the car
I recently bought a used 2016 Spark EV (having a baby and needed something other than my motorbike). It does have a touchscreen, but mostly for extraneous information and radio functions. Everything else has dedicated knobs and buttons. (The one dumb thing is that the fan speed updates on the screen, rather than just having ticks above the knob.)

It is a California "compliance car", which means it was just a modified petrol Spark, so it didn't have product managers trying to jam in unnecessary touch-based interfaces.

I just hope that all companies building electric cars don't move in the all-touch direction of Tesla.
