rmcpherson··on Cambridge's Ambitious Protected Bike Lane Law
This is often impossible when bike lanes are adjacent to parked cars.
rmcpherson··on 737 MAX crashes “linked” by satellite track data, FAA says
The debris found in Reunion island was likely handled by France as it is a French overseas department. Debris photos here: https://www.independent.co.uk/travel/news-and-advice/mh370-l...
rmcpherson··on Drafting Only Men for the Military Is Unconstitutional, Judge Rules
They do, but it's only possible to apply for CO status when drafted. You can not become a CO when registering with selective service. https://www.sss.gov/consobj I know because I tried.
rmcpherson··on Drafting Only Men for the Military Is Unconstitutional, Judge Rules
You could become a conscientious objector, and it’s even possible to get out of the military this way (my father did).

Unfortunately, the Selective Service does not recognize conscientious objectors when there is not a draft so it’s hard to get that status now.

rmcpherson··on Cheap Chinese electric cars are coming to the US and Europe
The difference is that it’s illegal to drive a motor vehicle without liability insurance. With other vehicles, that can be just as lethal to pedestrians or cyclists, there is no such requirement. In my case, the driver who hit me was homeless with no insurance of any kind.
rmcpherson··on Cheap Chinese electric cars are coming to the US and Europe
Exactly. This just happened to me when I was struck by a moped in a near-fatal crash. Because it is not a motor vehicle by insurance and Legal standards in the USA it does not require a license or insurance to operate. If you are hit by one of these, you’ll find there’s no insurance to cover you other than your health insurance. Underinsured coverage on your auto policy will not apply either, as it would if you were hit by a motor vehicle.

True but the U.S. has contributed hundreds of millions to the LHC and still does. https://www.aip.org/fyi/2008/us-contribution-lhc-budget-and-...
rmcpherson··on The Effect of Sleep on Happiness
It does get better with age in that your circadian rhythm will shift as you get older. It's a crime that we force adolescents to wake up far earlier than they are biologically wired to just so their parents can get to their jobs. According to Matthew Walker (Berkeley professor and sleep researcher), waking up at 7 is equivalent to an adult waking up at 5. Highly recommend his book on sleep. It's incredible, the best non-fiction I've read in the last couple years. https://www.amazon.com/Why-We-Sleep-Unlocking-Dreams/dp/1501...
rmcpherson··on Climate Change Can Be Stopped by Turning Air into Gasoline
This is something I’m interested as well. How are you making the transition?
rmcpherson··on Has wine gone bad?
While that was true to some extent 5-10 years ago, that is not the trend now nor has it been for several years. Hop flavor and aroma are the focus now of craft beer breweries, with significantly less bitterness.
rmcpherson··on A woman’s brain stimulator stopped working after her home struck by lightning
There are MRI-safe ICDs now. So they can be designed to avoid heating and mechanical displacement in MRIs. For ones not designed for this, such as yours apparently, it can be deadly though.
rmcpherson··on Comcast, AT&T and Verizon pose a greater surveillance risk than Facebook
It is more of a problem if you want to run the VPN on your router upstream of your devices, which simplifies management and ensures all devices are protected from ISP snooping, including devices where I don't control the software like a Chromecast.

I had to disable router-level vpn for exactly this reason, which is frustrating.

Amusingly enough, when I did have it on, my Chromecast showed weather data for the vpn endpoint so it's using IP-based geolocation for weather. It could be smarter.

rmcpherson··on Tracing doping use by amateur athletes from wastewater
That makes sense. I was thinking masters might be tested even at the amateur level but I guess that's rare even at the high levels of competition.
rmcpherson··on Comcast, AT&T and Verizon pose a greater surveillance risk than Facebook
One of the problems I've run into with using a vpn service is that many services block IPs from common vpn services. While this may be due to abuse originating from those IPs this still seems like a lazy approach to abuse prevention.

One approach that could work around this in many cases is to run a VPS with a private VPN server on a cloud provider. This is beyond the technical ability of the average user though and costs more than most VPN services.

rmcpherson··on Tracing doping use by amateur athletes from wastewater
Do you know why that is? It seems possible that it could be because masters racers started doping back before testing was prevalent/sensitive and now can't stop without a precipitous drop-off in performance that would raise eyebrows. Just conjecture though.
rmcpherson··on A dozen black holes may lie at the centre of our galaxy
Baryonic matter accelerating into black holes also emits electromagnetic radiation vs. dark matter which does not interact electromagnetically by definition (and observation).
rmcpherson··on Redesigning the Scientific Paper
Some scientists are using github as github for science, including development done in the open. For instance, this is just one particle physics project I happen to be aware of https://github.com/DisplacedHiggs

Open development is a policy for these projects and part of the grant stipulations.

Of course, data sets are more closely guarded initially until the groups that created them can publish. After that, though, CERN /LHC has done a decent job of making data publicly available from my understanding (not as someone directly involved).

I would be interested to hear more from scientists involved in projects doing open science.

rmcpherson··on MIT severs ties to company promoting fatal brain uploading
For a fascinating and realistic exploration of what that might look like, I recommend Kim Stanley Robinson's Mars Trilogy. In the series, a longevity treatment is developed that significantly extends lives. Beyond the strain on resources, there are the issues of older generations delaying progress by not relinquishing power (much like the current octogenarian U.S. congress) and other issues.
rmcpherson··on The differences between tinkering and research (2016)
Scihub has made virtually all academic papers freely accessible.
rmcpherson··on Why there are so many online mattress-in-a-box companies
This is all true, however even among all-malt beers there is significant variance in the quality of ingredients. That doesn't mean that there is no pretense but that high-quality beers can be measurably better (GCMS, blind sensory tests etc.) than less expensive ones made with cheaper inputs.
rmcpherson··on How to Quit a Top Tier Tech Job
An acronym for The (fucking) article. From RTFM/RTFA. https://www.urbandictionary.com/define.php?term=TFA

Despite the expletive it's not usually used in anger.

rmcpherson··on Hubble finds first galaxy in the local universe without dark matter
To clarify, no one's taking MOND nearly as seriously as WIMPs in terms of funding for experiments to test it. That said, the lack of evidence has lead to increased interest in alternative theories that could explain the phenomenon. Some of these are alternative dark matter particle candidates though, just not WIMPs.
rmcpherson··on Hubble finds first galaxy in the local universe without dark matter
This finding certainly weakens the case for MOND. The authors write that in the conclusion of their paper, as quoted in this article: https://arstechnica.com/science/2018/03/galaxy-seems-to-lack...

MOND can not explain a galaxy without dark matter as it is a proposal for the modification of the laws of gravity at large distances, and can explain the already-observed galaxies that behave as if they have dark matter (or, as MOND posits, the laws of gravity are different than what we have observed on earth.)

rmcpherson··on Hubble finds first galaxy in the local universe without dark matter
I used "strongest candidate" not as my opinion (I don't know) but that is how physicists see the various possibilities. Certainly WIMP research has received the largest amount of funding in experimental physics as compared to other candidates.
rmcpherson··on Hubble finds first galaxy in the local universe without dark matter
I was talking with some physicists from Fermilab last week about dark matter (I'm a physics enthusiast but certainly no physicist) and one thing they were discussing was how current dark matter experiments are constraining possible dark matter candidates significantly as they get more sensitive without finding any. This has lead to increased interest by physicists in alternative theories, including MOND. This galaxy discovery, though, appears to be strong evidence against MOND or other modified-gravity theories since the dark matter is missing in this case. It provides more evidence for dark matter's existence, even as the strongest candidate, Weakly Interacting Massive Particles (WIMPs) are becoming more constrained by lack of evidence.
rmcpherson··on The stability implications of the US nukes' burst-height compensating super-fuze
This general problem discussed in this article, a technological change affecting the perceived nuclear arsenal balance, is a reminder of the existential peril of nuclear weapons that we have seemingly forgotten since the fall of the Soviet Union. In some ways this peril has never been greater than it is today with unpredictable leaders of nuclear powers and ever-decreasing barriers to entry for nuclear weapons (e.g. North Korea).

As Einstein said in 1955, when the existential threat was both new and real, “You may reasonably expect a man to walk a tightrope safely for ten minutes; it would be unreasonable to do so without accident for two hundred years.”

We are complacent at our species’ peril. How many intelligent civilizations in the universe have ended shortly after the dawning of their nuclear age? That’s one possible explanation for the Fermi Paradox.

Thus far, humans have been unable to resist use of a technology to gain power and the abstention from use of nuclear power seems only as strong as the current world power structure, which will inevitably fail. There are no easy solutions to this problem but it’s one we must solve to survive. Perhaps we even need to change ourselves biologically, as a species. To engineer ourselves off the paleolithic savannah into one fit to survive in the modern world of nuclear powers and interconnection.

rmcpherson··on Space catapult startup SpinLaunch comes out of stealth
Not to mention the acceleration needed to achieve orbital velocity with a catapult. Seems like insanely high forces on the payload. I’d love to see how they solve this.
rmcpherson··on iPhone update for Meltdown-Spectre: before/after performance benchmarks
I wonder what the difference is between the 6 used in the benchmark in the article and the iPhone X that would cause these different results. They both support speculative execution.

Either way, encouraging results to a fellow iPhone X user.

Why would longitude affect an image like this? Can you elaborate?
