Earlier this year, the Seattle-based startup launched its first two satellites into orbit on SpaceX's Transporter-10 rideshare mission from Vandenberg Space Force Base on the central coast of California. Since then, they have successfully received signals from a simple 3.5mm Bluetooth chip over a distance of 600 km... According to the company, connecting any off-the-shelf Bluetooth device to Hubble's satellite network via a software update - even without cellular reception - could potentially offer global coverage with 20 times less battery drain and 50 times lower operating costs. Countless applications utilizing existing low-power, low-cost sensors could be developed without the need for additional expensive space-enabled hardware.

Water Cooler / The Modern Curse of Overoptimization
« on: May 06, 2024, 07:33:09 PM »
I’ve been thinking about a related problem - the inherent unhappiness of people who try too hard to optimize in life (I generally refuse to use the phrase over optimize because logically that is impossible).

Here’s Freddie’s take on the social downsides of optimizing services.

My current working definition of overoptimization goes like this: overoptimization has occurred when the introduction of immense amounts of information into a human system produces conditions that allow for some players within that system to maximize their comparative advantage, without overtly breaking the rules, in a way that (intentional or not) creates meaningful negative social consequences. I want to argue that many human systems in the 2020s have become overoptimized in this way, and that the social ramifications are often bad.

Traffic / How much would students pay to have Tik Tok banned?
« on: April 24, 2024, 10:49:47 PM »
Interestingly, you have to pay college students more to quit Tik Tok than to quit Instagram. But if you tell them that they if they get enough people join, they will ban them campus-wide, they will PAY more to ban TT than IG.

So it seems they see IG as both less important and less destructive

They wouldn't do it if you just had restrictive zoning laws that prevented people from building any houses.

Chart: NC now builds almost as many housing units as CA

Traffic / Small site SEO is dead
« on: April 04, 2024, 02:54:52 AM »
I see more and more people taking about their niche sites getting obliterated. In the old days, when people made this complaint and I looked at the sites, they were usually junk. Now they are usually excellent.

I previously posted this

I haven’t checked this one out, but it popped up in my feeds today.

Retro Dodo is on the brink of collapse… because of Google.

I’d take issue with that phrasing - the site *exists* because of Google. But the general problem…

Then this…

Scroll through the comments and @craig somebody has the same graph for a totally different site.

I haven’t seen this kind of carnage on tourism sites, but despite decent spend on content creation, the sites I know have seen a slow but inexorable decline in traffic despite many new high-quality articles from professional writers with decades of pro writing.

Are ANY niche sites from independent publishers gaining ground, or even holding steady, from SEO/content dev alone (in other words, no ppc, limited feeding from social, etc)?

As the AI shitstorm heats up, this can only get worse.

ChatGPT is known to overuse the word “delve” and it’s use has skyrocketed in PubMed papers.

Economics & Investing / GenZ is becoming the tool belt generation
« on: April 02, 2024, 12:13:38 AM »
As college costs rise and so do salaries in the trades, Gen Z are becoming electricians and plumbers. The median age for those two professions is falling and enrollment in vocational schools is increasing much faster that enrollment in 4-year colleges

After 30+ years of predicting this and being wrong, maybe I’m finally right

Hardware & Technology / is much better than Google
« on: March 25, 2024, 01:47:52 AM »
For the longest time, we've wondered what search engine will dethrone Google.

Now that the LLM chatbots are getting so good, it has become evident the above question is like asking, "What directory is going to dethrone Yahoo!?" (thankfully, one that makes punctuation look correct).

Example... I saw that the cardiac stroke volume of a blue whale is 80 liters (and a human can swim through the aorta). I wondered what the stroke volume of an elite endurance athlete is. I tried several searches in Google, got a bunch of scholarly papers that didn't answer the question. I gave up and went to Claude in seconds it gave me answers and I thought, "I'm never going to Google again for this type of thing," just like that day when I thought, "I'm never going to Ask Jeeves again."

What is the stroke volume of an elite cyclist

The stroke volume of an elite cyclist is typically higher than that of an average person due to the physiological adaptations that occur with regular endurance training.

Stroke volume refers to the amount of blood pumped out of the left ventricle (one of the heart's chambers) with each contraction or heartbeat. It is measured in milliliters (mL) per beat.

For elite endurance athletes like cyclists, the stroke volume can range from around 120 mL to 200 mL or even higher in some cases. In contrast, the average stroke volume for an untrained individual is usually between 60-100 mL.

The higher stroke volume in elite cyclists allows their hearts to pump a greater amount of oxygenated blood to the working muscles with each beat. This adaptation, along with a higher maximum heart rate and greater blood volume, enables their cardiovascular system to better meet the increased demands of intense endurance exercise.

However, the exact stroke volume can vary depending on factors like the athlete's age, sex, body size, and individual training status. Elite cyclists undergo specific training to improve stroke volume as part of their overall cardiovascular conditioning.

Is that the stroke volume at rest or during exercise?
The stroke volume values I provided for elite cyclists (120-200 mL) generally refer to their stroke volume during maximal or peak exercise, not at rest.

At rest, even elite endurance athletes like cyclists will have a stroke volume closer to normal untrained values of around 60-100 mL per beat.

Here's a more complete picture:

Resting Stroke Volume:

Untrained individuals: 60-100 mL
Elite cyclists: Around 60-120 mL
Maximal Exercise Stroke Volume:

Untrained individuals: 70-130 mL
Elite cyclists: 120-200 mL or higher
The larger maximal stroke volumes seen in elite cyclists (120-200 mL) represent the high end of their cardiac output capabilities during intense cycling when their hearts are working at maximal capacities.

This increased maximal stroke volume allows their hearts to pump more oxygenated blood per beat to working muscles during maximal aerobic exercise compared to untrained individuals.

So in summary, while elite cyclists may have only a slightly elevated resting stroke volume, their stroke volumes increase substantially more than untrained people during heavy exercise when their cardiovascular systems are most challenged.


Overall, these findings support that exosomes produced from stem cells can be a neuro-protective therapy to alleviate AD pathology.

Alzheimer's has the worst ratio in medicine for shots on goal vs points scored. So many shots, so few scores. But lately, things seem to be actually moving in AD research. It might still be too late for a lot of us here, but I would say that AD for people under 40 will be somewhere between prostate cancer and polio for people my age (60).

Water Cooler / March 10: Remember to adjust your tape measures
« on: March 10, 2024, 10:38:56 PM »
Those of you living in the more enlightened parts of the world where we have no truck with socialist abstractions like centimeters and kilograms should remember that today is the day we update to the US Summer Weights and Measures.

Be sure to update your scales, tape measures, and cooking implements to Summer Weights and Measures values until November 3.
17 ounces to the pound
9 ounces to the cup
13 inches to the foot.

Of course, all other measures stay the same, so while there are still 63,360 inches to the mile, during the summer there are 4873.8461 feet to the mile, as God intended.

Though I have posted this before, for any who missed it, this documentary explains how our glorious system in the land of the free came to be:
