The web interfaces use SDRs. They can listen to an entire band at one time rather than just a single station.

You will only be able to listen to transmissions that are within range of a web SDR. They work great for HF since that propagates a long ways when the band is open. For VHF and up, you will likely need a local receiver unless there happens to be a web SDR near you that covers the band you want to listen to.

The web SDRs may have better antennas than you do and they are probably in a place with much less RFI than you. You can use them to listen to far away places.

LiFePO4 batteries are safer and harder to ignite, but they can still go into thermal runaway and can burn. If a fire started in a battery that big, it would still spread and it wouldn’t be practical to extinguish it.

None of the scanners on VirusTotal picked up anything. What makes you think the PDF if malicious?

It looks cool, but I’m worried about durability. It doesn’t even make the screen that much bigger.

That’s still significantly better than having no markings at all.

A decent lipo can charge at 5C, but it significantly reduces the cycle life. They are claiming 1000 cycles at that charge rate.

The lack of physical media will just drive more people to piracy.

The Motorola DynaTAC. They had a big Ni-Cd battery that is also the back of the case. You would need often need two batteries to get through a whole day, so they were made to be easily swapped.

So they can sell you a new phone instead of a replacement battery.

Swapable batteries were common on cell phones in the 80’s and 90’s except no fancy machine was needed.

That was LORAN-A. It would get your ship close enough that you could see your destination. LORAN-C was comparable to GPS with selective availability enabled. eLORAN will be almost as good as GPS.

I will probably still be using 1080P in 10 years. I’ve had a 4K TV for a long time and still don’t have any 4K content.
The only thing I would like 8K for is a computer monitor for CAD, but that certainly won’t be using HDMI.

There are projectors with DisplayPort, but HDMI and VGA are more common. Laptops usually use the USB-C DP alt mode to output DisplayPort signals. HDMI requires a separate port. USB-C can output HDMI, but very few devices support it and it will never be updated past HDMI 1.4.

It’s very rare and you certainly won’t find it on anything affordable. I wish they would start putting DisplayPort inputs on TVs. They had VGA inputs back when TVs had more than 2 inputs on them.

HDMI only won on TVs. DisplayPort is the clear winner on PCs.

The only things that really matter are storage space and power consumption. If you want to transcode videos, then you will need a GPU that supports encoding whatever codec you want to use.

I’ve been using zoneminder with some POE IP cameras for a long time. It works pretty well, but the interface looks like it’s from the 90’s. I just wish it would do object detection so it wouldn’t send alerts because of shadows or a spider crawling across the lens.

My cameras have been out in the weather for over a decade and are starting to get a bit flaky. I will probably upgrade to some 4K analog cameras and a DVR that can do object detection. Modern IP cameras still don’t support gigabit and I don’t want any more 100M stuff on my network. I don’t trust WiFi for anything security related because it’s too easy to jam.

It’s better to disable ssh password login and use keys instead.

You don’t need 64 bit programs or CPUs to fix the 2038 problem. You just need to use a 64 bit time_t. It will work fine on 32 bit CPUs or even 8 bit microcontrollers.

Let me know when someone gets an LLM to run on a Bendix G15. This Pentium stuff is way too new.
