I wonder what's the size of avg 108MP image, it's probably near 100MB. TB+ storage in phone would be in order too.

Up to 40MB per image.
But 108 megapixel is just a big number for marketing. Most people don't know the difference between pixel count and image resolution.
Simplified, image resolution is how much detail is visible. And that is really what you are after, but not what you are going to get. You'll simply get a lot of pixels without much detail.

huh? The more pixels, the better the detail - how are you not getting more detail?

They describe it in the article like it's almost entirely for digital zoom. The software crops the images and rarely, if ever, saves a full size photo.

...and 108% pointless.
Without some sort of optical zoom, this seems most likely, not sure what value there is in such a high pixel density - though, that said, things like portraits for billboards, it could be useful, printing anything that large definitely benefits from having more details.

Because it's like upgrading your NIC from 1 gigabit to 10 gigabit and then find out that when you surf the web nothing is faster than before.
The actual image resolution is a chain of things. The biggest bottleneck is the lens. The lens can't resolve the amount of detail that a 108 megapixel sensor can. Also to make the lens compact and light you have to make optical compromises and then fix those in the camera software. That will also lower the resolution.
The next problem is that 108 megapixels on a small sensor means very small pixels. A pixel converts photons into electrons. A small pixel will have a lot of noise because it can not collect a lot of photons. Unfortunately noise obscures details so more noise means lower resolution.
Also to actually get high resolution you have to hold the phone extremely still during exposure. That's why you see landscape photographers using tripods and remote triggers to take pictures without touching the camera.
Just a few things. That being said, in a lot of situations it's better to have more pixels rather than less even if the difference might not be what you think.

Also, the optics and sensor are more important than the Mp count.

https://store.ui.com/collections/routing-switching/products/unifi-dream-machineWhat's with the cylinder design? Don't the designers and engineers have cats? I think it started with Amazon Echo, now everybody has to have cylinder. I lost count how many times my cats have knocked down my Echo, I'm surprised it's still working.

Breaking the law: How 8chan (or “8kun”) got (briefly) back online
Russian "bulletproof" host advertised stolen IP address to take site live.
The successor to 8chan, 8kun, made a somewhat brief appearance on the public Internet thanks to what amounts to an attack on the Internet's routing infrastructure. The site's domain name server, hosted by a service called VanwaNet, offered up an Internet address for the site that was from an unallocated set of addresses belonging to the RIPE Network Coordinating Centre, the regional Internet registry authority for Europe and the Middle East. And the host for the new site, the Russian hosting company Media Land LLC, advertised a route to that address to the rest of the Internet, allowing visitors to reach the site for a while. -

https://store.ui.com/collections/routing-switching/products/unifi-dream-machineThis is the typical fail. Optimal placement of a single AP is rarely where the demark to the house is.
If you drop this in your living room, you need to use the Cable jack that you're likely wanting to use for the cable box near your TV, if you don't have cable, that might not be an issue - but you still have to the the cable modem near this device - so that's just one more piece of IT junk not in a closet where it belongs.
Do they really think everyone lives in Texas where there are no/nearly no basements?

Xiaomi’s Apple Watch clone removes everything good about the Apple Watch
The Xiaomi Mi Watch combines Apple design with Wear OS and a CPU from 2011.
Xiaomi has gone back to its roots as a purveyor of shameless Apple ripoffs, and hot off the photocopier is the Xiaomi Mi Watch, a new wearable that is decidedly Cupertino-inspired. The Mi Watch is an Apple Watch clone, but the design is pretty much the only thing that's cloned here. You won't get a good SoC, a good operating system, good battery life, good haptics, or a good app ecosystem. From a distance, though, some people might mistake the Mi Watch for an Apple Watch, and maybe that's enough. -
Meet MLPerf, a benchmark for measuring machine-learning performance
MLPerf benches both training and inference workloads across a wide ML spectrum.
When you want to see whether one CPU is faster than another, you have PassMark. For GPUs, there's Unigine's Superposition. But what do you do when you need to figure out how fast your machine-learning platform is—or how fast a machine-learning platform you're thinking of investing in is? Machine-learning expert David Kanter, along with scientists and engineers from organizations such as Google, Intel, and Microsoft, aims to answer that question with MLPerf, a machine-learning benchmark suite. Measuring the speed of machine-learning platforms is a problem that becomes more complex the longer you examine it, since both problem sets and architectures vary widely across the field of machine learning—and in addition to performance, the inference side of MLPerf must also measure accuracy. -
UAP-BeaconHD
The UniFi AP Beacon HD is the fastest way to extend Wi-Fi coverage and increase throughput in your home or office. The sleek design integrates easily into any environment and plugs into a standard US wall outlet. The 5 GHz uplink connection is 15 dB stronger than typical Wi-Fi devices, which results in more than a 4x larger Wi-Fi coverage range in an open space. -
Rocket Report: Aloha to Hawaii launch site, China tests grid fins
"Use of a commercial launch vehicle would provide over $1.5 billion in cost savings."
Welcome to Edition 2.22 of the Rocket Report! This week, there is a lot of news on medium-sized launchers, as well as the first real estimate for the combined marginal and fixed costs of a Space Launch System flight. Also, I want to note that this report will not publish next week as the author will be taking time off to work on a book project. As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar. -
