netinstructions··on How Being Hit by a Vehicle Changed Times Colleagues’ Lives (2014)
Makes me think of a recent incident in Seattle where an aggressive driver in a large truck sped up and passed intentionally close to a bicyclist to intimidate them (incredibly, incredibly dangerous). This happens frequently enough as any cyclist can attest, but it was special because it was caught on camera and shared with the police. The cyclist tried to report it as attempted murder (and even the former mayor of Seattle described it as such), but the police department said, "This looks like an inconsiderate/unsafe pass. An officer would typically need to witness a violation in-progress to be able to stop the driver & confirm their ID to issue a citation." Nevermind that there was clear video of the whole thing.

About a month later a car hits and kills a cyclist and runs away. Who knows, maybe the driver was trying to do a non-prosecutable "inconsiderate/unsafe pass" that got a little too close.

netinstructions··on Is ‘Oumuamua an alien spacecraft? First scans show no signs of technology
They mentioned that they're scanning a frequency range from 1 to 12 GHz.

Why that range? And what if it's transmitting at 0.5 or 13 GHz, or 500 GHz? Would that show up, just weaker or..?

netinstructions··on The Great American Share – Sam Altman Interview on Basic Income
Sure that could be the goal, but when you run a small pilot you can't just ignore the existing policies and laws...

Also it's not the main benefit of UBI. It's just one benefit (or side effect) of UBI - when it's universal (not just a pilot) you can reduce the overhead of administrative costs.

Some more details (besides the announcment) here for the curious https://www.theatlantic.com/science/archive/2017/12/yuri-mil...

It'd be crazy if we detected radio signals, in part because we don't really have a good way to send any probes fast enough to visit it closer as it speeds away from us, at least with current technologies. There's more on that here: https://arstechnica.com/science/2017/11/so-you-want-to-send-...

netinstructions··on Angular 5.0.0
I was in the same boat - Watched Angular 2 presentations live (was it ng-conf or something?), was excited about Angular Universal and the Angular CLI that was announced.

Turns out the CLI didn't play nice with Universal. I spent a week trying to convert the bare bones Angular 2 tutorial 'tour of heroes' into an Angular Universal architecture. I couldn't figure it out. Lots of version mismatches and either out of date or 404'd documentation.

I just gave up. If I couldn't convert a simple project to do server side rendering there was no way I'd be able to convert a more complicated project.

netinstructions··on Show HN: Bitcoin investing using Dollar Cost Averaging strategy
The example says they want to invest $1000 over the course of 3 months, so 1000 / (3 * 30) = 1000 / 90 = ~11$ / day.

But aren't the transaction fees (at least for Bitcoin) something like ~$2 per transaction? So you'd end up only investing ~$820 instead of the target of $1000 and losing the rest. Am I missing something?

netinstructions··on Amazon Hub
Was kind of hoping this is something individual home owners could install near the front door so packages aren't left on the steps.

If you fill out the form it asks what kind of property you have, and single family homes is an option, but then it says "your property does not meet our requirements at this time." I wonder if enough people select that though...

netinstructions··on Cars overwhelmingly cause bike collisions, and the law should reflect that
> Source?

https://en.wikipedia.org/wiki/Idaho_stop

It's safer[1], and other places (California[2], Denver[3] from a quick Google search) have looked to implement similar laws.

You probably only notice when the cyclists don't take "due care" before they proceed into an intersection. Of course there will be dumb people, but the chances of them causing injury to anyone else is still tiny compared to cars. You're missing all the times (quiet streets, quiet times of the day) when no one is around and it doesn't make sense to wait for a light (and for cars to show up that'll probably pass too close by the cyclists when the light turns green).

netinstructions··on Cars overwhelmingly cause bike collisions, and the law should reflect that
Some of those things you've listed are not safe practices at all.

Riding on the sidewalks are legal in some places (sidewalks are OK to ride on in Seattle as many of the multi-use trails join up with them and the roads do not have shoulders), and same with "running" red lights - in Idaho cyclists are allowed to do this[1] as it's proven to be safer[2].

netinstructions··on Cars overwhelmingly cause bike collisions, and the law should reflect that
> The actual root cause is probably more related to cyclist visibility

Sounds like you've never commuted by bicycle before. I've seen people decked out in high-vis clothing carried away in ambulances or their bikes found under car wheels with their headlights and tail lights still on. But don't take my word for it[1], the actual studies themselves aren't very conclusive either[2].

The actual root cause is likely inattentive drivers, poor roads/infrastructure, and the all too common drivers' mentality that "bikes don't belong on the roads" many cyclists encounter on a regular, day-to-day basis when drivers feel justified in passing too close, cutting cyclists off, or turning into them.

netinstructions··on Elon Musk's tunnel plan is surprisingly outdated–and bad
> He does say he’s working on developing a TBM that simultaneously digs and reinforces tunnels, one of the big engineering challenges for tunneling. Musk should have given his TED Talk on that instead of this surprisingly archaic idea for addressing vehicular congestion.

I too have more hopes that this could "dramatically change the way we build and finance infrastructure" than all the other aspects of Musk's electric sleds for cars and the associated elevators that go with them to ferry cars around underground.

However, a TED talk on TBMs is a boring, unrelatable talk. A TED talk on how we can "drive" our cars around awful traffic is something many, many Americans can get excited about. Even if I agree with the article author that the assumption that cars are the de facto way to get around is misguided and wrong.

In other words, let's appeal to the affluent car-centric/politicians/lobbyists in cars so we can get better TBMs for public transportation projects down the road that those demographics don't usually support anyways.

netinstructions··on Solar Roof
This is something they're specifically trying to address. Elon posted some high speed footage of a "hail gun" shooting the Tesla tiles.

Sounds like a fun job to build and operate a "hail gun"

netinstructions··on 3D scanning like a pro
Another way of doing this is something like Google's project tango, right? [0][1]

So you can build and code this up (which sounds like a fun project) or if you're lazy or lack the time you can buy a $512 portable device that probably has an app or two to do 3D scanning out of the box.

Both approaches have their pros/cons but both are pretty neat and it's exciting that it should only be cheaper and easier for hobbyists to play with in the years to come.

netinstructions··on Introducing Stack Overflow Trends
This is almost a better version of the tool I made a couple years ago to compare Stack Overflow tags - http://www.arepeopletalkingaboutit.com/

Only difference is that I try to highlight the number of answered questions, since a bunch of unanswered questions is less helpful than a bunch of answered questions.

netinstructions··on Scaling your API with rate limiters
Reminds me of a website I built once (more like a side project) where I anticipated heavy loads and all sorts of nefarious users / bad situations so I spent a good chunk of time implementing and testing rate limiters into most of the critical requests.

I ended up getting maybe... 3 or 4 well-behaved visitors / day for the first two years.

netinstructions··on Show HN: Bless your JavaScript code
You know it's an excellent package just based on how straightforward and readable the source code is.

My only gripe-- do you think you could expose the blessing id more easily? My work around is to parse the returned string, but I feel like it's a bit of a hack.

netinstructions··on Startup Serves Up Chicken Produced From Cells in Lab
Can you speak to the cost? The WSJ article says it currently costs $9,000 per pound to produce the "clean meat". Does that mean you ate something like a $900 chicken? (Assuming you had a small sample)
netinstructions··on Google Fiber Was Doomed from the Start
SpaceX plans to have satellites at 1,100 kilometers (680 mi) altitude unlike previous attempts / current offerings. Latency would be closer to 25-35 ms.

netinstructions··on Show HN: Amazon Price Monitor (weekend project)
I haven't had any issues using Camel Camel Camel for the last few years.

Additionally, I usually go there for price history when trying to figure out if now is a good time to buy or when trying to figure out what a good price threshold is to receive alerts. Without historical price info it's hard to know what a good "max price" is to set.

netinstructions··on Show HN: Amazon Price Monitor (weekend project)
FYI, camelcamelcamel gets around this emailing users link to a special page on their (camelcamelcamel.com) site that is just a redirect to the product page on Amazon. Users see a brief message "Thanks for using Camel Camel Camel" or something shortly before being redirected.

I'm sure that won't be a PR disaster when news/blogs/twitter find situations where Google Maps suggests to avoid certain neighborhoods, statistics be damned.
netinstructions··on VR social productivity app Bigscreen raises $3M with Andreessen Horowitz
I can't wait for VR resolution to increase so things like this work really well.

From my experience using the Oculus dev kit 2 there was too much of a "screen door" effect and it was hard to read text on a virtual monitor vs reading text on a real life monitor. It wasn't practical to use a virtual monitor to say, write code or surf the web.

But resolution will only get better! At that point will things get fun and I can see people eschewing monitors for VR "monitors".

netinstructions··on Interview with John O'Nolan of Ghost
I migrated from Wordpress to Ghost (using some sort of provided Ghost tool) and my site started getting way more hits from search engines.

I'm guessing it's because the ghost site was noticeably faster and was mobile friendly, which my old WordPress site was not. I didn't do any SEO tuning or anything.
