cbdumas··on The Poor ROI of Autonomy (2020)
> The model most are working toward is "hub to hub" not point to point. As in, A human driver drives the truck from the warehouse or port to a hub on the highway outside the city surface streets. Then they get out of the truck and pick up another one that needs to go back into the city.

What's the competitive advantage of this setup over a train?

cbdumas··on GraphQL Is a Trap?
The "Graph" part of GraphQL is entirely optional, and IMO not worth the trouble. The best way to use GraphQL is to use it more like an RPC framework, as a replacement for calling generic HTTP endpoints that return JSON blobs. The front end libraries that support it are great and well maintained and you get the additional structure of the GraphQL type system.
cbdumas··on Mechanical Watch
This page got the HN hug of death it seems. Absolutely deserves all the traffic he is getting, Mr. Ciechanowski's blog is an absolute gem.
cbdumas··on Ask HN: Why do negative crypto articles dominate on HN?
Because HN readers skew more technologically literate, people here are on average (slightly) more capable of seeing though the techno-babble hype than on other social media sites. It's not that the financial status quo is held in high regard, rather that HN readers see crypto's empty promises to fix existing issues for what they are: bullshit designed to lure in ever more dumb money.
cbdumas··on Parking kills businesses, not bikes or buses
> reorganizing housing across the whole society to massively increase density and to mix commerce zoning with homes

Exactly.

cbdumas··on The Welfare Effects of Dynamic Pricing: Evidence from Airline Markets
Why don't retailers of luxury durable goods use dynamic pricing? Surely Best Buy would love to charge the actual market price (~$800 from a quick eBay search) for a PS5. Sony could just auction batches of consoles to retailers and let them price / promote however they want. Instead they stick to MSRP, leading to shortages at retailers and leaving lots of money on the table for resellers. I don't get it.
cbdumas··on Prediction that Kyiv falls to Russian forces by April 2022 goes from 90% to 26%
Apply to what? Lithuania has been a NATO member since 2004. This is literally the "eastward advance of NATO" which you referred to as a "moral mistake". You contradict yourself.
cbdumas··on Prediction that Kyiv falls to Russian forces by April 2022 goes from 90% to 26%
How do you think you would feel about that if you lived in Lithuania?
cbdumas··on Germany aims to get 100% of energy from renewable sources by 2035
I think the comment you're responding to was using that as an example of a "silly opinion" that needs revising.
cbdumas··on On iPhone sideloading: it’s ok, I’m changing my mind
If both iOS and Android allowed sideloading this would be a much more attractive option. As it stands something like that isn't really worth while because most high-value consumers of mobile apps use iOS.
cbdumas··on Coinbase’s philosophy on account removal and content moderation
I really can't tell if the comment you are responding to is satire. "I don't know why Coinbase would ban me all I did was use their platform to launder money"
cbdumas··on The New York Times buys Wordle
This makes perfect sense and fits in well with their games subscription offering [0]. I'll be sad to see Wordle go behind a paywall but this is great for the creator.

cbdumas··on The New York Times buys Wordle
This seems to fit very nicely into the set of mini games they sell a separate subscription to. And if their own claims are to be believed it seems that they have already successfully monetized them https://www.nytco.com/press/both-cooking-and-games-reach-1-m...
cbdumas··on The Future of E-Bikes
Can't speak for everywhere but in Washington state almost anything sold as a scooter or moped in fact requires a full motorcycle endorsement, liability insurance, annual registration, etc. The cutoff for a motorcycle endorsement is a max 49cc motor or 2 brake horsepower, which excludes nearly everything sold as a scooter that I can find.

You are certainly right that in most of the US biking infrastructure is embarrassingly bad, hopefully if pedal-assist ebikes get more popular that will spur more investment in bike paths and separated infrastructure.

cbdumas··on Failing to Learn Zig via Advent of Code
Why include the infix operators at all then? If it's just as clear without them maybe even machine native types don't need them.
cbdumas··on Failing to Learn Zig via Advent of Code
I think vector math is a compelling example but it is far from the only one. Bignum arithmetic is probably just as common if not more so, in fact I see that Zig actually has a bignum library built in if I understand correctly. Using that library will be painful because of this choice. There are plenty of other such examples, imagine implementing (and then using) something like SymPy in Zig.
cbdumas··on Failing to Learn Zig via Advent of Code
What did you think of the example in the article about vector math? Seems like that's an area where operator overloading actually makes the code more readable. Maybe it depends on the problem domain you're working in.
cbdumas··on United States IPv6 adoption over 50%
I got IPv6 working via 6rd on my Mikrotik router a few weeks ago following this forum post https://forum.mikrotik.com/viewtopic.php?t=160314#p788221

If you don't need a tunnel it should be pretty painless, just set up firewall rules and enable IPv6 forwarding

cbdumas··on Hidden Networks in TP-Link Routers
While we're talking routers I'll plug Mikrotik. Some basic knowledge of the Linux networking stack is required so they're not great for a general user, but for ~$50 I got a device that handles my setup with ease (Ipv4 over PPPoE and IPv6 over 6rd) and I'm seeing throughput significantly higher than my previous router which was a Zotac mini computer running pfsense. If you are more toward the power user / networking nerd end of the spectrum I'd recommend Mikrotik.
cbdumas··on Google delays mandatory return to office beyond Jan. 10
At the risk of sounding like a broken record, what you wrote to me here is absolutely dripping with condescension. Maybe we just don't agree on what that word means? In my view, writing the following to a stranger whose life you know nothing about could be a passable definition of "condescension":

> If you want to stop feeling bad, you need to actively start figuring out new possible ways to feel better. Working on building relationships with friends, neighbors, members of your local community is a good place to start.

cbdumas··on Google delays mandatory return to office beyond Jan. 10
This is first of all so condescending and second of all so defeatist. Isn't it possible to have a life outside of work and still want to leave your house and see people IRL for the 8+ hours per day you spend working? Just because I have friends and hobbies doesn't mean I have to love working from home.
cbdumas··on Ask HN: Best cars without too much digitalization?
I'm surprised by the tone of the responses here so far. As much as we might or might not like the new digital user interfaces in modern cars, the value of the safety features like automatic braking and collision avoidance is pretty much beyond contest at this point[0]. Before you buy a car without these features, consider that you are probably not as good of a driver as you think you are.

cbdumas··on Ask HN: Why is the Spotify UX so horrible?
FWIW the Google Podcasts app on Android is great. I never use Spotify to listen to podcasts anymore.
cbdumas··on What caused all the supply chain bottlenecks?
I'm definitely outside my wheelhouse here, so maybe help me understand the current fixation on and criticism of JIT. Are you advocating for more buffers in supply chains generally? If the current scenario is one where goods purchases were simply deferred from early in the pandemic to later (with no real increase in total demand for goods) I can see that solving the issue to some extent.

But my point is that total demand for goods has actually increased and not by a little, by a lot. Buffers in the supply chain can't help with that, can they? An increase in total throughput is needed to solve that, and that's going to take a while. Is there something I'm missing here?

cbdumas··on What caused all the supply chain bottlenecks?
The data in my second link is a quantity index, so I believe price is not a factor
cbdumas··on What caused all the supply chain bottlenecks?
All of this talk about supply chain issues are totally missing the point in my opinion. So many articles (and tweet chains I guess) have been written about supply chain issues, yet every one of them seems to ignore the elephant in the room which is demand for goods vs services. Over the course of the pandemic there was a staggering re-balancing of consumer spending [0] from services to goods, to which supply chains have not caught up.

If the spending doesn't re-balance again as restrictions are lifted this is not a temporary supply chain issue caused by just-in-time methodology, it's just the new normal.

cbdumas··on Is Ford about to reinvent the bicycle derailleur?
The fact that ABS isn't standard on more bikes (especially e-bikes) is crazy to me.
cbdumas··on It feels like America is running out of everything
That's absolutely true, but is that what's happening? That seems like a really important question for this article (and the legion of others like it) to tackle. The linked article even mentions demand in the subhead, and then basically ignores it in the actual body. Thus my frustration.
cbdumas··on It feels like America is running out of everything
There has been endless coverage of the supply side of current economic weirdness affecting the world, but scant coverage of the demand side. Yet if this blog post[0] that was discussed here a couple of weeks ago is to be believed spending on goods in the US shot up by 20% this year. It seems to me that even if global supply chains were working flat out and in perfect order we would still see huge disruptions given a shock to demand of that magnitude. I would love to see more detailed reporting from a knowledgeable source on this.

cbdumas··on Biden to mandate coronavirus vaccine for federal workers
> covid vaccines do not prevent infection

This is untrue, see this site and the studies in the footnotes: https://www.cdc.gov/coronavirus/2019-ncov/variants/delta-var...

TL;DR: Vaccines are effective, though not perfect, at preventing infection with the delta variant
