  • If you haven’t gotten one in a bit

    I wish guidance on when to get a booster shot was more prevalent. I remember them pushing the first 3 rounds at various intervals, but it wasn’t too difficult to follow if you were paying attention. Now it’s just “get your COVID shot”, but little-to-no mention of how often.

    I know it’s complicated, depending on if you’ve been vaccinated before, and which version(s) you got. It seems that, assuming you’re an adult who has been vaccinated up to this point, it’s now just an annual shot like the flu, but the CDC page mentions “the updated shot” with a long list of notes about when various versions were updated. It would be nice if it was just “if your last vaccination was more than X months ago, it’s time for another”.

    I guess, if you have questions, the general advice of “talk to your doctor” applies.


  • Unfortunately, DMCA abuse rarely has consequences for those behind it.

    Oh look! The actual problem is buried at the end of the article.

    It’s my understanding that filing a DMCA request requires that you certify that you have reviewed the content, and confirm that you believe the content to be infringing.

    Here’s an excerpt from a sample takedown notice, provided by Georgetown University:

    I am providing this notice in good faith and with the reasonable belief that my rights as the exclusive rights holder are being infringed.

    Under penalty of perjury, I certify that the information contained in this notification is both true and accurate

    I know that “reasonable belief” gives a lot of wiggle room from a legal standpoint, but c’mon. If no one pushes back on that, of course it will be abused!







  • The fundamental relationship between smart-home companies and their customers is founded on trust.

    Man… I’d like to be able to live in their world. In reality, it seems the fundamental relationship is based on “this is convenient and cheap enough that I’m willing to give up some privacy in that aspect of my life.”, but I’d never classify it as “trust”. I’ve had internet connected cameras. I would only ever place them outside my house. My garage door also had a camera watching it, just in case my smart garage door opener decided to act up unexpectedly.

    Of course, I still have a smart phone in my pocket. I guess I’ve essentially given up on that front.


  • the possibilities of head-on collisions and left turn-related crashes are virtually eliminated

    intended to slow drivers to speeds where crashes are far less severe.

    I’ve definitely heard that they’re safer, but this just seems to indicate that the crashes aren’t as bad. Are there also fewer crashes?

    Although some studies point to roundabouts causing higher numbers of minor crashes ― a point which WisDOT recognizes in its manual ― Qin said, in terms of injury severity, roundabouts are considerably safer.

    Oh… ok. Not dying is a perk, but I’m sure everyone will be super stoked to be in more accidents that are right around the cost of their insurance deductible.

    It often feels harder to drive defensively in a roundabout (especially multi-lane roundabouts) when I need to look over my left shoulder to make sure it’s clear to merge while also looking to my right to make sure that the guy in the lane next to me or the other guy getting on at the next entrance know to yield to me. In a traditional intersection, all “conflict points” that the article mentions are in front of you as you enter the intersection.


  • how much space would one need to generate enough water for say, an average household in South Korea?

    Alright, here are some “back of the envelope” calculations based on the information available. I hope I don’t screw anything up, and please ignore my utter disrespect for significant figures.

    The Mayo Clinical says that the average person needs about 2.7-3.7 liters of water per day. Normally, this comes from both food and beverage, so how much of that you actually need to drink is going to vary depending on your diet, but let’s assume worst-case scenario, where all of your water comes from this device.

    Given the stated output, and the fact that water conveniently has a density of 1kg/L, it seems that you’d need anywhere from 9-18kg (20-40lbs) of MOF to produce enough water for one person per day if this was your only source.

    (1kg MOF/0.285kg water * 1kg water/1L water * 2.7L water/person = 9.5kg MOF/person)

    (1kg MOF/0.210kg water * 1kg water/1L water * 3.7L water/person = 17.6kg MOF/person)

    ArcGIS says the average household in South Korea is 2.4 people, so now we’re at 22.8-42.2kg (50-93lbs) of MOF to meet the water requirements.

    I have no idea what the density of MOF is, so I don’t know how much space this would take up. Metals vary significantly in density, but we can look at Aluminum (2600kg/m^3) and Lead (11,300kg/m^3) to get some idea of range.

    22.8kg * 1m^3/2600kg = 0.00877m^3

    22.8kg * 1m^3/11,300kg = 0.0020m^3

    42.2kg * 1m^3/2600kg = 0.0162m^3

    42.2kg * 1m^3/11,300kg = 0.0037m^3

    I’m struggling to come up with “real world” equivalents to help you visualize the volumes. The smallest one is a sphere about 16cm (6.3in) in diameter. The largest one is a sphere about 31cm (12.2in) in diameter.

    Obviously, the device wouldn’t be a sphere, and it wouldn’t be made of just MOF. The diagram showed a tube of MOF wafers surrounded by a container, but that should give you a very basic idea of the materials required. Again, this is all assuming I didn’t make any mistakes, which feels like a bold assumption at this point.









  • Meanwhile, this article told (reminded?) me that we have a mental health hotline service.

    These missed calls are happening at a time when most Americans still aren’t aware the 988 national suicide prevention and mental health hotline exists — and even as we hit the service’s one-year mark, few states have established long-term funding commitments to sustain it

    Plans to use some of the nearly $1 billion in federal funding for a nationwide public service campaign haven’t materialized, partly due to early concerns that marketing 988 could overwhelm the lifeline past capacity.

    Well, good thing they aren’t marketing it. We wouldn’t want 1/4 of the calls to go unanswered or anything…

    “It’s taken 15 years for 911 to evolve to the kind of system that it is today. We’re just one year in.”

    I mean, a 15 minute wait in a mental health crisis still doesn’t sound like an ideal goal, but I guess it’s better than being completely ignored.
