Verizon 5G Ultra Wideband compared to a 56K dial-up modem

by philg

Our neighborhood in Jupiter, Abacoa (created by the MacArthur Foundation), is home to a Major League Baseball training stadium at which the St. Louis Cardinals and Miami Marlins practice. A light post beyond the outfield bristles with mobile phone antennae, which presumably includes one for Verizon. Sitting in the stands, exactly one baseball field away from these antennae, I was unable to use a web browser. Here’s a Speedtest result:

Decoding the above: Max signal strength. On the new 5G Ultra Wideband network that Verizon advertises. Sub-LTE download speed. Upload speed, which is presumably making it tough for me to request pages, almost the same as a 56K modem dialing up AOL on an analog phone line (see Brent Townshend’s patent filed in 1994, which kept patent litigators busy for even longer than Verizon kept me waiting for web pages).

Young people: AOL was like Facebook and Twitter except that you wouldn’t be kicked off for saying that you believed masking kindergarteners wouldn’t stop an aerosol virus. Also, the typical user didn’t spend time and energy raging against things done by governors and legislatures of states other than the user’s own.

A 13-inch iPad costs the same as an 86-inch TV with the same capabilities

by philg

An iPad Pro costs between $1,100 and $2,200 (plus $350 for a keyboard), depending on precise configuration. It features a 12.9-inch LCD display and weighs about 1.4 lbs., making it inexpensive to pack and ship. It runs a Unix-based operating system and a bunch of apps to decode streaming digital video and paint pixels on the medium-resolution (less than 4K) screen.

What about an 86″ TV? It runs a Unix-based operating system and a bunch of apps to decode streaming digital video and paint pixels on a full 4K resolution screen. Here’s an example LG 86UN9070AUD from a recent Costco trip:

In addition to its prodigious 7′ diagonal size, it weighs 100 lbs. (130 lbs. when packaged) and therefore consumes substantial shipping and warehousing costs.

An obvious answer is that LG competes with other TV manufacturers and Apple is the only place to get a device that will run all of the apps targeted to iOS, but it still surprises me that these two items could have roughly similar prices.

13 percent raise for Amazonians

by philg

A friend works as a “DevOps Engineer” at Amazon in Maskachusetts. She just got a 13 percent raise, not performance-based, to compensate her for inflation and prevent her from quitting.

State-sponsored NPR today says that the inflation rate is just 8.5 percent: “U.S. inflation rises 8.5 percent, sharpest increase since 1981”. Is that number consistent with our Lived Experience?

What if you want to buy a replacement rebuilt engine for your little airplane? There was a 14 percent price increase in July 2021. There was an additional 15 percent price increase in March 2022 (Rotorcorp). So prices are up 31 percent compared to a year ago? Not if we hold delivery time constant. The Rotorcorp article:

Perhaps the most challenging issue out of Lycoming is not just the spiraling prices, but the extended and growing lead times. At time of this writing, Rotorcorp is still waiting on Cylinder kit orders placed in July of 2021 and has had lead times “bumped” numerous times to in excess of 12 months for some parts. Engines are now in excess of 8 months.

Rotorcorp is responding with increased rolling inventory replenishment orders to maintain critical spares stock to support our customers, but we are HIGHLY encouraging customers approaching 2200 hour service, or needing engine overhaul/replacement to place their cylinder and engine orders up to 9 months ahead of anticipated delivery.

So the apples-to-apples price might be 50 percent higher (you’d have to buy out someone else’s order to get an engine within a few weeks as was previously standard).

Let’s try not to ask about the rebuild price on the engine in this P-40 (from Sun ‘n Fun 2022):

Permanent Temporary Free Internet

by philg

From the New York Times, April 3, 2022, apparently not satisfied with A corrected history of mRNA vaccines, its January 15, 2022 effort to erase Robert Malone:

This post is not about the obviously false claim that someone whose name appears on a foundational paper regarding mRNA vaccines had something to do with the invention of mRNA vaccines. (See also Nature‘s history of mRNA vaccines, which devotes the first three paragraphs to the now-unpersoned Malone and mentions his name 27 times.) It is rather about the possibility that our family could get free Internet rather than handing over $780 per year to AT&T for gigabit fiber! Of course, I clicked on the ad (landing page):

If it’s “free” then I assume it is paid for by taxpayers. What does Comcast say about this taxpayer-funded program?

“a longer-term replacement for the Emergency Broadband Benefit.” So the temporary emergency government program (#BecauseCOVID) has morphed into a permanent entitlement. The FCC explains this:

It’s not the government taking $14 billion every year from one set of residents of the U.S. and using it to pay whatever Comcast and the, ahem, competitors are charging another set of residents. It is instead an “investment in broadband affordability,” implying that broadband prices for Americans who haven’t been organized enough to get into the welfare system might start coming down to European rates.

I will have to revise my standard description of what a low-skill or elderly/infirm immigrant to the U.S. can expect to receive from existing taxpayers. Before it was free housing, free health care (Medicaid), free food (SNAP/EBT), and free smartphone (Obamaphone). The FCC explains eligibility for this new permanent entitlement:

If you’re on SNAP or Medicaid, in other words, you’re seamlessly eligible for free home broadband connection. So now it is free housing, health care, food, smartphone, and broadband.

(Speaking of Medicaid, remember that April is Medicaid Awareness Month!)

Circling back to the Xfinity ad landing page, here’s the final picture of someone in a household that might benefit:

Taken together, these three pictures have me wondering if we should try to go on welfare so that we’d finally be living in a clean clutter-free house!

GPU performance improvements since 2015 (and why not just use motherboard graphics?)

by philg

Moore’s law says that we should get GPUs twice as fast every two years (GPUs are inherently parallel so adding more transistors should add performance). Huang’s law says that GPUs get 3X faster every two years.

Because everything desirable in this world is being scooped up by the Bitcoin enthusiasts, my seven-year-old desktop PC makes due with a seven-year-old ASUS STRIX GTX980 graphics card. It was purchased in April 2015 for $556 from Newegg.

A similar-priced card today, exactly seven years later, should be at least 10X faster, right?

The 2015 card’s benchmark:

It can do 47 frames per second with DirectX 12.

Let’s look at the $1,050 RTX 3080 for comparison. Using the same inflation rate as Palm Beach County real estate, $1,050 today is a little less than $556 in 2015 dollars.

It can do 98 frames per second with DirectX 12. Even the cards that sell for $2,000+ are only slightly faster than the RTX 3080.

I pride myself on asking the world’s dumbest questions so here goes… if building a new PC for activities other than gaming or video editing, why not use the integrated graphics on the motherboard? The latest motherboards will drive 4K monitors. The latest CPUs have a lot of cores, especially AMD’s, so they should be competent at tasks that are easy to parallelize. Back in 2020, at least, a graphics card was only about 2X the speed of AMD’s integrated graphics (Tom’s Hardware). Intel, it seems, skimps in this department.

One argument against this idea for those who want a fast desktop PC is that the fastest CPUs don’t seem to come with any integrated graphics. The AMD Threadrippers, for example, say “discrete graphics card required”. The Intel Core i9 CPUs with up to 16 cores do generally have “processor graphics”, but does it make sense to buy Intel? AMD’s CEO is frequently celebrated for identifying as a “woman” (example from IEEE, which does not cite any biologists) while Intel’s CEO identifies as a surplus white male. Tom’s Hardware says that the latest Intel CPUs are actually faster for gaming: “Intel holds the lead in all critical price bands … In terms of integrated graphics performance, there’s no beating AMD. The company’s current-gen Cezanne APUs offer the best performance available from integrated graphics with the Ryzen 7 5700G and Ryzen 5 5600G.”

Is the right strategy for building a new PC, then, to get the Ryzen 7 Pro 5750G (available only in OEM PCs; the 5700G is the home-builder’s version) and then upgrade to a discrete graphics card if one needs more than 4K resolution and/or if the Bitcoin craze ever subsides? The Ryzen 7 fits into an AM4 CPU socket so it won’t ever be possible to swap in a Threadripper. This CPU benchmarks in at 3337 (single thread)/25.045 (the 5700G is just a hair slower and can be bought at Newegg for $300). The absolute top-end Threadripper PRO (maybe $10,000?) is no faster for a single thread, but can run 4X faster if all 128 threads are occupied. What about the Intel i7 5820K that I bought in 2015 for $390? Its benchmark is 2011 for a single thread and 9,808 if all 12 threads are occupied.

(For haters who are willing to pass up chips from a company led by a strong independent woman, the Intel i9-12900KS is about $600 and includes “processor graphics” capable of driving monitors up to 7680×4320 (8K) via DisplayPort. It can run up to 24 threads.)

These seem like feeble improvements considering the seven years that have elapsed. I guess a new PC could be faster due to the faster bandwidth that is now available between the CPU and the M.2 SSDs that the latest motherboards support. But why are people in such a fever to buy new PCs if, for example, they already have a PC that is SSD-based? Is it that they’re using the home PC 14 hours per day because they don’t go to work anymore?

  • Best Integrated Graphics (from Feb 2022; AMD Vega 11 is the winner)
  • ASUS “gaming desktop” with the Ryzen 7 5700G and also a GTX 3060 graphics card (could this ever make sense? Is there any software that can use both the GPU packaged with the CPU and simultaneously the GPU that is in the graphics card?)
  • William Shockley, who needs to be written out of transistor history: “Shockley argued that a higher rate of reproduction among the less intelligent was having a dysgenic effect, and that a drop in average intelligence would ultimately lead to a decline in civilization. … Shockley also proposed that individuals with IQs below 100 be paid to undergo voluntary sterilization”

People who were afraid to leave their bunkers for two years want to wear the same watch as the Apollo 11 astronauts

by philg

Two Apollo 11 astronauts wore the Omega Speedmaster after riding the Saturn V to the moon. Swatch has recently released a replica “moon watch”. Demand for these watches, and an association with the men who were brave enough to go into space, was overwhelming (Daily Mail). I would love to know how many of those who are donning the Watch of Bravery were cowering in place for two years, wearing an N95 mask while walking in the woods, etc.

Here are the original and copy side-by-side:

If you got some of the $500 billion in fraud from the PPP and other Covid relief programs, you might prefer this $45,300 gold version that is so white it looks like inexpensive stainless steel (so the Justice Department won’t suspect you!):

Which one would I choose if I were going into space? None of the above! Everything in aviation is done with UTC so I’d want a 24-hour hand or a 24-hour digital display of UTC in addition to the 12-hour local time. Torgoen makes a lot of these (quartz movements) and, if you want to spend 30X as much to get the same function, the Rolex Explorer II (except that it will cost you 50X as much and you’ll have to accept a used one because new Rolexes, all million/year that they make, are sold out (at least one to this guy who got caught defrauding PPP)).

Why is the markup on electricity for charging cars higher than the markup for gasoline?

by philg

Electrify America charges 43 cents/kWh in Florida:

That’s 4X the average price to a commercial customer in the state (EIA.gov; which shows that Electrify America’s price is 5X the “industrial” rate, which might be more appropriate for a large and busy charging station). (Let’s ignore the membership price of 3X because you can get a fair price at a gas station without joining any clubs.)

Retail gasoline is about 10 percent over cost (source), i.e., 1.1X.

The gas station needs to dig a tank, maintain pumps, insure against environmental calamity, fire, etc. The electric charging station just needs a few parking spots, some wires, and some high-power/high-voltage components.

For people who live in apartments and/or do most of their charging on trips, do these huge charging station markups eliminate the purported fuel cost savings for high-cost electric cars? (we almost never see a Tesla used as an Uber, right?)

Swiss versus American CEO

by philg

From an interview with the Markus Bucher, the CEO of Pilatus (in Switzerland)….

For the first time we produced and delivered over 140 aircraft to our customers in one year, taking us virtually to the limit of our current production capacity. The enormous demand for our General Aviation aircraft, the PC-12 and PC-24, exceeds all our expectations!

The interviewer, from an in-house magazine, asks “Were our ambitious corporate goals achieved in 2021?”

2021 was a mixed year… I’m not entirely happy! Demand is incredibly positive and our finances are very health. But we work inefficiently and we remain under a lot of pressure because of the need to bypass many standardized production processes due to faulty materials and insufficient quality from our suppliers.

Readers: let me know if you can find anything similarly candid from a U.S. CEO (other than Elon Musk)!

Meet at Sun ‘n Fun this weekend?

by philg

Who else will be at Sun ‘n Fun this weekend in Lakeland, Florida? For those who are unfamiliar with this glorious event, it is a gathering of aviation enthusiasts that is a little more manageable than Oshkosh (EAA AirVenture).

To prevent a January 6-style insurrection within the family, I splurged on the $25 Preferred Airshow Seating for Saturday so that would probably be the easiest way/place to meet.

Rich Harvard graduate joins the Supreme Court

by philg

The NYT, under a headline about “A Transformative Justice”:

Judge Ketanji Brown Jackson will help make the Supreme Court look like the nation but will have little power to halt its rightward trajectory.

Judge Ketanji Brown Jackson, the first Black woman confirmed to the Supreme Court, will in one sense transform it. Once she replaces Justice Stephen G. Breyer, one of the 108 white men who preceded her, the court will look a lot more like the nation it serves. … there will be two Black justices. And a Latina.

U.S. Census says that the percentage of Americans who identified as Black in 2020 was 12.4 percent. If a numerate person were setting up racial quotas for the Supreme Court, therefore, just 1 out of 9 justices (11.1 percent) would identify as Black. With 22.2 percent Black justices, for those who “see color”, the Supreme Court will actually look less like the nation it serves.

Maybe it isn’t about the skin color criterion established by President Biden, but about socioeconomics. Wikipedia says that Ketanji went to Harvard undergrad, then Harvard Law School, and is married to a surgeon from a “Boston Brahmin” (i.e., rich) family. So someone from a household containing two Harvard graduates and enjoying an income of at least $1 million per year will make the Supreme Court look like more of a cross-section of typical Americans?

Separately, let’s look at microaggressions from the world’s nerds. Microsoft Word recognizes “Ketanji” as a legitimate word/name yet here in a text area on Google Chrome it is flagged as a spelling error. (Who else on Planet Earth has a first name of “Ketanji”?)

From CNN:

The Senate confirmed President Joe Biden’s Supreme Court nominee Ketanji Brown Jackson on Thursday in a historic vote… Vice President Kamala Harris, the first Black woman to serve as vice president, presided over the chamber during the historic vote in her capacity as president of the Senate. … Senate Democrats and the White House have continually highlighted the historic nature of the nomination. … The Senate chamber was packed for the vote, with most senators seated at their desks for the historic occasion.

We have all just witnessed a historic event. What will change as a result of this rich Harvard graduate joining the Supreme Court?

Finally, if Ketanji Brown Jackson were to change her gender ID to “man”, thus disqualifying himself from the job under the race+gender ID criteria established by President Biden, would he be subject to impeachment? CNN seems to think that Ketanji Brown Jackson and 2SLGBTQQIA+ are related topics:

Notice the ad at right regarding a TV biography of Elizabeth Holmes, who certainly made history as the first teenage multi-billionaire founder of a chemistry company without any degree in chemistry.
