Is there such a thing as too many pixels?  For the most part do any of us need really sharp clear pictures or is that lower quality image people post on facebook and forget about good enough.  Why take a four meg picture if preservation and clarity isn't important?

If everyone has a great camera on their cell phone why don't we have quality pictures/movies of big foot, ghosts or UFOs yet?

I think it has to do with light sensitivity and noise levels. The smaller the sensor cell, the more prone to Johnson noise it'll be, which means you need to keep that sensor *cool*, which phones just can't do. There's a reason why DSLR bodies are big and have some heft to them. It's mostly heatsink and glass.

Concerning UFOs, you try to take a picture of a transient aerial phenomenon in the dark with either your phone or DSLR. Shutter speed alone guarantees a blurry image, particularly since people just don't carry tripods in their back pockets, have the time to set them up, etc.

I get pretty sick and tired of people asking "why don't we have clear pictures of UFOs" when anyone who's even tried to image a star could handily answer that question in a heartbeat.

(and what pisses me off, is that people who ASK that question usually actually HAVE astrophotography experience. They should be ashamed of themselves.)

I thought the problem was interplanetary space vessels are not visiting earth, you are saying it is a lighting issue?

You're making the illegal assumption that UFOs = aliens.

I've seen many UFOs; however, that doesn't mean they're not of terrestrial origin. Regardless, even supposing they WERE visiting (purely for sake of discussion), you *still* couldn't get a good picture of one unless you managed to set up a tripod, frame the picture, set your exposure setting, select the right lens to focus on the object, set your 10s timer (to allow vibrations in the tripod to dampen), then *click* and wait.

So, I guess what I'm saying is that it is utterly immaterial *what* UFOs are; the *very question* of why we don't have good night-time photos of one and putting the blame on the photographer as evidence of non-existence is a logical fallacy committed by those who really ought to know better.

Indeed, if one *could* get an accurate photo at night time, 99% of the time, the phenomenon could be explained. This is a self-biasing data set.

It's not about the heat - it's about the size of the photosites.

I already mentioned that. The smaller the individual pixels in the sensor, the more prone they are to thermal noise. They are related.

How much of the difference is not due to the phone hardware but the software that takes the picture ie stabilization, etc?  Of course a "camera" today is probably the combination of both the software and the hardware.

I guess people could switch to using another camera app like opencamera which would throw in another variable.

Instead of "UFOs" I prefer the World War II era phrase: "foo fighters"

If we have aliens coming from other planets, I'm guessing we can build a wall for that too.

I read today that, 

Since Android 6.0 it's required to have GPS permissions in order to run Bluetooth

What is the connection between GPS and Bluetooth?

I am not sure if this came up in my YouTube recommended list or it was posted here.  Who is the man named ᚼᛒ and how did Bluetooth get its name?

Tomorrow I'm going on a trip to visit the technology labs for a company we do a lot of business with.  Should be pretty cool.  But...

To read the itinerary for the day's events, they required us to install an app on our smartphones.

WTF?  There's no special functionality in this app.  Just an agenda for the day and some directions to the place etc.  Have they not heard of this wonderful thing called "web pages" ?

In a perfect world, there would be no apps.

Andy Rubin, the former Citadel sysop and inventor of Android, has a new startup.

[2~https://www.essential.com/

They seem to be intent upon building a cohesive system of smart devices that all talk to each other, but the first product is a high-end Android smartphone.
It looks very slick.

Going forward, Essential's plan seems to be devices that are "your personal property" (no locked down anything, no forced bundles, all open source software), open ecosystem, premium materials, long hardware lifecycle, and simple.

This is where I usually include a smart-ass remark but I can't think of one right now.
