Don’t Call Them Earbuds

I’m abusing the headphone jack on my laptop PC by playing two different pairs of In-Ear-Monitors, or IEMs, at the same time. I’m abusing my ears by going back and forth between them.

Positive reviews on AudioScienceReview for inexpensive “Chi-Fi” IEMs made me curious, resulting in this post from a month ago.

In One Ear, In the Other

A guy in Singapore who goes by the handle Crinacle is a leading reviewer of these products. His influence extends to him collaborating with manufacturers to evaluate and fine-tune the sound of their IEMs.

After listening to the BLUE set with his name on it, I was curious about the RED set. The models are identical in design and construction except for the sound, with the RED tuned to Crinacle’s preference. As expected from the reviews, it’s more balanced sounding than the BLUE.

That would typically be my preference, but I feel that something of the baby was thrown out with the bath water, and I actually prefer the brighter BLUE with its excellent deep bass. The extension piece on one of the cables is a bass boost for the RED that I think muddies the sound like the loudness buttons that used to be standard on amps and receivers.

Unlike some other hobbies and pastimes, where the next generation of fans failed to show up (stamps, coins, bowling, et. al.), many young guys are actively involved in appreciating audio and music. Being young, there are some snarky reviews of IEMs on YouTube, but the overall tone is positive and fun. As is seen here, where the youngsters are questioning an elder audio expert, while remaining respectful.

Follow-up: Both of these IEM’s are keepers. The extra $5 for the RED edition seems to be for the booster adapter. Curiously, on the Lenovo laptop it makes the sound a little muddy, but with my phone it seems to have no effect. Maybe it’s an impedance thing.

There’s No Stopping Progress

Nobel Prize economist Robert Solow has died. Solow was awarded the Presidential Medal of Freedom by Obama. It’s an honor that was subsequently tarnished by Trump giving one to Rush Limbaugh.

As [Solow’s] work shows, technological advances, broadly defined, are responsible for the bulk of modern economic growth

Solow’s obituary in The New York Times has this amusing quote about John Kenneth Galbraith.

Mr. Galbraith “mingles with Beautiful People; for all I know, he may actually be a Beautiful Person himself.” But the book, he said, “is for the dinner table, not for the desk.”

I think Solow’s “beautiful person” crack may have revealed a bit of the old M.I.T. vs. Harvard rivalry. Meeting the very tall Galbraith was a pivotal event for me in deciding to make Economics my college major.

Coincidental with Solow’s passing, last night’s PBS Newshour has this segment on AI’s potential effects on employment. It was mostly recorded at Boston’s Museum of Science (which is actually in Cambridge), where one of my sisters works developing educational materials.

For a deeper dive into the work of Robert Solow, there is this interview from just six months ago. It was conducted by his former student, economist Steven Levitt.

The Little Generator That Could

We’ve had the second storm of the season that, in the past, would have been a blizzard. Instead, it’s 60 degrees with high wind and heavy rain.

The power went out this morning and the utility doesn’t have an estimate when it will be restored. I fired up the portable generator and recharged my phone, which is now running as a Wi-Fi hotspot for the new laptop PC.

Yes, the garage floor needs to be resurfaced. It’s on the list.

Being An Elf to Myself

This is my new Lenovo laptop PC, but with a 14″ screen. Not being an Apple product it can’t be cool, but Lenovo tries.

Buying it required me to abandon my “never spend more than $300 on a laptop” rule. But it was a good deal for a 14-inch laptop with a partial aluminum case, an Intel i7 CPU and 16 GB memory, with a touch screen and lighted keyboard. USB-C charging was something else I wanted, which HP doesn’t have yet. The 2-in-1 feature, turning it into a tablet, wasn’t of special interest.

I was surprised to see that its dimensions, except for thickness, are almost identical to the old HP ProBook 11 G2 with its 11.6-inch screen. The ProBook has something that, along with optical drives, is extinct in laptop computers. It has a VGA connector. This makes it perfect for the 4:3 projector that I sometimes have set up in the living room. It’s a 2005 model purchased as new-old stock for $65, plus $10 shipping.

The Lenovo’s 2200×1400 IPS LCD screen and out-of-the-box color accuracy are exceptionally good. The sound of the speakers is impressive for a laptop, but audio is directed to the porch’s 10-year-old Sony Bluetooth speaker. It was an early product supporting Qualcomm’s proprietary Bluetooth codec, aptX.

Not too many changes were needed in Windows 11 to make it behave the way I want. Something about Windows 11 I don’t like is that support for aptX, which is found natively in Windows 10, has apparently been dropped.

Be Careful What You Lick or Click

Here is an example of where AI software could be of some direct benefit, but it has yet to be applied. At least I hope not, otherwise we’re already in big AI trouble.

I’ve been looking for something Disney-related on YouTube, and this ad appeared.

Watch the Barbie movie… for free?? Gosh, it must be a Christmas promotion or something! It can’t be a scam, can it? I mean, Google allowed it on YouTube, right? But, just in case, I’d better check the official Barbie movie site.

Hmmm… there’s nothing there at all about watching the movie for free. So where is that YouTube ad coming from?

BULGARIA?? RUN AWAY………… !!!
