The Fermi Paradox among us · Sunday March 15, 2026 by colin newell
When confronted with the topic of stars and galaxies, a question that tantalizes most humans is, “Is there other intelligent life out there?” Let’s put some numbers to it—
As many stars as there are in our galaxy (100 – 400 billion), there are roughly an equal number of galaxies in the observable universe—so for every star in the colossal Milky Way, there’s a whole galaxy out there. All together, that comes out to the typically quoted range of between 1022 and 1024 total stars, which means that for every grain of sand on every beach on Earth, there are 10,000 stars out there.
The science world isn’t in total agreement about what percentage of those stars are “sun-like” (similar in size, temperature, and luminosity)—opinions typically range from 5% to 20%. Going with the most conservative side of that (5%), and the lower end for the number of total stars (1022), gives us 500 quintillion, or 500 billion billion sun-like stars.
There’s also a debate over what percentage of those sun-like stars might be orbited by an Earth-like planet (one with similar temperature conditions that could have liquid water and potentially support life similar to that on Earth). Some say it’s as high as 50%, but let’s go with the more conservative 22% that came out of a recent PNAS study. That suggests that there’s a potentially-habitable Earth-like planet orbiting at least 1% of the total stars in the universe—a total of 100 billion billion Earth-like planets.
So there are 100 Earth-like planets for every grain of sand in the world. Think about that next time you’re on the beach.
Moving forward, we have no choice but to get completely speculative. Let’s imagine that after billions of years in existence, 1% of Earth-like planets develop life (if that’s true, every grain of sand would represent one planet with life on it). And imagine that on 1% of those planets, the life advances to an intelligent level like it did here on Earth. That would mean there were 10 quadrillion, or 10 million billion intelligent civilizations in the observable universe.
We review the XHDATA D-221 ultra-portable AM-FM-SW-Weather radio · Monday February 17, 2025 by colin newell
It has been said many many ways before: You don’t really need something until you don’t have it – and in this world of ultra-connectedness, this could not be more true than the absence of a simple radio during a crisis.
And in this drama filled planet, where we depend on our cell phones, personal planner brains and other assorted cloud based/cell tower dependent gadgets, the battery powered radio has never been more important.
But the average person does not get this concept – for one reason or another – like they have never been in the middle of an earthquake zone, or a country with some unexpected civil unrest or the unpleasant aftermath of some conflagration or another.
And it is during moments like that where panic and bewilderment can set in extra quick when one is 100% in the dark.
Solution: Stay connected. Be connected. Be prepared.
How? With a radio.
And XHDATA was kind enough to send me a radio to play with and evaluate for our technical/non-technical audience.
Let’s dig in: The XHDATA D-221 weighs in at 171g with a standard 9V battery.
It measures 12cm long, by 7cm wide by 3cm thick – meaning it sits in the palm of your (girl or boy) hands just fine.
Usage: If, like me, you grew up in the 60’s, 70’s or 80’s, you know the look and feel of the standard transistor radio – whether it be a handheld portable, discretely pocketable, or something larger for the kitchen counter – or something even larger that you might balance on your shoulders… radios and their usage comes pretty much naturally.
The XHDATA D-221 is no different. It is the model of simplicity: Volume control (with integrated power switch) and tuning control on the right (as it faces you) and band selection switch on the left. Nothing more. Nothing less.
Step by step: Power on. Extend antenna. Select band of interest. Adjust volume and tuning dials.
If you were expecting more bells or whistles, worry not. There are no bells. There are no whistles.
The XHDATA D-221 works very well on AM and FM. During the day, the AM dial picks up all the familiar stations you expect to hear and at night the XHDATA D-221 comes alive with long distance signals from 700 to 1000 km away or more. Not surprising. Any decent AM portable is going to hear distant stations. Our local FM dial is chock-a-block with signals – and all of those signals were present on the D-221 with perfect clarity via the internal speaker or through headphones via the stereo headphone jack.
The Weather-band network of marine stations were all crystal clear at my location near the Southern tip of Vancouver Island.
If I have one criticism, it was, for me, the Shortwave portion of the dial. While I live in something of a shortwave fringe area up here in the Northwest, I am also not really in a high intensity AM zone – but I do have a lot of powerful FM transmitters not too far away. Consequently, the SW dial of the D-221 was a wash of images (or birdies as they are often called) and no evidence of shortwave reception. This could be a bug of this particular sample or a byproduct of my listening environment. Either way, it was not an issue that would stop me from having one in my travel or emergency kit.
The XHDATA D-221 comes in at around $20 – via Amazon, or XHDATA direct or where ever you get your gizmo’s.
Pick one up. Better yet. Buy three and have one in your car, your home tote and send one to a friend. You never know, it might save their life or yours.
The XHDATA D-608WB - a radio for every application · Wednesday July 24, 2024 by colin newell
It is not everyday that a radio drops into my lap for the purposes of testing and day to day use.
So it was to my delight when the good folks at XHDATA contacted me with an offer: “Let us send you a radio. You put it through its paces. See what it can do. And put a review on your DXer.ca website.”
Hey! I can do that. So here goes.
The XHDATA D-608WB radio is described more as an emergency radio than a standard counter-top or totable radio.
Its dimensions make for an item that fits comfortably in the hand – at 15 cm long, 7.5cm wide and 4 cm deep it has a place in every emergency pack.
Why should everyone have this radio in their emergency kit?
The radio covers AM, FM, Shortwave and the weather band with impressive sensitivity. I had no trouble capturing all of my regional AM stations — and after sunset, all the clear channel stations were loud and clear – many from over 1000 miles away.
The FM sensitivity was comparable to all of my larger portable.
Sound quality is great for such a small package and is pleasant enough for hours of listening.
Shortwave sensitivity and selectivity was surprisingly good for a radio that appears to try to do everything.
All of my regional weather band stations (within 70 km away) came in crystal clear.
There are hundreds of memories available on the XHDATA D-608WB for your fav stations. The XHDATA D-608WB has auto-add of stations to memory during scanning! XHDATA did not appear leave out any desired features with this radio.
The radio is powered by a rechargeable battery. It can be charged via a USB cable (supplied), via solar cells built into the radio or from a hand-crank generator also integral to the radio! The radio comes with an Tri-level LED reading light (integrated underneath the solar panel array on the top of the radio! The radio comes with a very bright emergency light (or torch as some call it…)
The radio is also a selectable Bluetooth speaker — with great audio quality. So, you can pair it with your iPhone or Android device and any PC, Mac or Linux desktop/laptop! Not only that, when it is paired with your phone you can actually accept phone calls! I tested it. It worked flawlessly!
While watching YouTube on my iPhone (and paired with the XHDATA D-608WB radio, one can fast forward and skip between videos with buttons on the XHDATA D-608WB! What a great feature.
So. Bluetooth speaker – this opens access to unlimited podcast listening.
What’s more, the XHDATA D-608WB accepts the TF card – so fill your boots with MP3 audio and Podcasts! This radio just keeps getting better!
I recently travelled to Calgary, Alberta, Canada (a one hour flight from Victoria B.C. where I live…) and the XHDATA D-608WB radio came along with me. Airport security did not bat an eyelash at the radio — to them it appeared to be just that, a travel radio.
In conclusion, the XHDATA D-608WB is for all intents and purposes, the Swiss Army knife of radios – it does almost everything anyone would want out of a travel or emergency radio. I found no fault in the radio and give two solid thumbs up for this product — and look forward to sampling and testing other XHDATA products!
Stay tuned for a YouTube video on this product on my YouTube channel and a subsequent podcast!Colin Newell in a resident of Victoria B.C. Canada – on the West Coast – on Vancouver Island.

Instant Pot Living - Delicious Lasagna in 45 minutes · Monday April 22, 2019 by colin newell
I have been a fan of good pasta since I was eating solid food. My mom made me spaghetti and meat balls when I was still in the high chair and I have photos of yours truly eating this dish with my bare hands!
I have evolved a bit in the intervening years and, for me, the delight in eating tomato based pasta dishes has never waned.
We have been using the wonderful Instant Pot for almost a year now and finally got around to attempting a lasagna.
This recipe did not disappoint – and my thinking now is: Why make a huge batch that you invariably need to freeze when you can cook one up that is good for one big family meal or (in our case) enough for 2 with several servings left over.
Let’s dig in!
Ingredients
1 lb ground beef
8 oz ricotta cheese
1.5 cup mozzarella cheese – divided in half
1/2 cup Parmesan cheese – divided in half –
1 egg
Italian spices – Oregano and Basil
Salt and Pepper to taste
No-boil lasagna noodles
1 jar pasta sauce
1/2 box thawed spinach
Prepare spring-form pan with tin wrapped around the outside and oil spray the inside.
Brown the ground beef (salt and pepper to taste)
Combine all of the ricotta, half of the mozzarella and parmesan cheese, egg, and the spinach. Mix it together.
Take dried lasagne noodles, breaking into suitable shapes to fit bottom of spring-form — this your first layer.
Open jar of pasta sauce.
Put enough sauce to cover first layer of noodles (1/3 of jar)
Take two ladle fulls of ground beef to spread over your layer of pasta sauce.
Take 1/2 of the egg cheese mixture and place on top of the meat layer.
Repeat sequence again: Noodles, sauce, ground beef, cheese mixture.
Add last layer of noodles and pasta sauce.
Take the rest of the cheese mix left over and place on top.
Create a “hood” of aluminum foil (oil sprayed on the inside – so cheese doesn’t stick…)
Add 1 cup of water to bottom of instant pot.
Place springform pan in silicone sling.
Lower sling onto Instant Pot trivet.
Set to high pressure for 20 minutes. Natural release for 11 minutes.
Remove from instant pot – put on baking sheet – remove tin foil hat – broil for 5 minutes to brown cheese.
Serve with garlic bread and/or Caesar salad. Serves 6.
