Because in 1981 or so, everybody was pretty sure that this fairly obscure educational network would *never* need more than about 4 billion addresses... and they were *obviously right*.

The discussion about grains of sand or atoms is pretty silly. The reality is that the idea of 1 item, 1 address is already hogwash. It's very typical for one address to host *many somethings* (EG: websites, NAT, etc) and the opposite is also equally true: it's very typical for one something to respond to many addresses.

There are many applications that we likely can't even consider due to today's limitations that may well depend on or benefit from a large address space. IPv6 is a definite step in the right direction, but having seen the transition from 8 -> 16 bit computers, 16 -> 32 bit computers, and the transition from 32 -> 64 bit computers, the reality is that **growth is exponential**.

When 2% of your address space is consumed, you are just over 6 doublings away consumption. Even if you assume an entire decade per doubling, that's less than an average lifetime before you're doing it all over again.

IMHO: what needs to happen next is to have a 16 bit packet header to indicate the size of the address in use. This makes the address space not only dynamic, but MASSIVE without requiring all hardware on the face of the Earth to be updated any time the address space runs out.

I'm using an MK809 Android TV stick that cost me about $35 on Amazon. Plays my Samba shared media over wifi flawlessly, as well as Hulu/Netflix/NBC/CBS, all while using the USB port on my TV as its power supply. It really doesn't get much more efficient than that.

Instead of a TV remote, I use a "flying mouse" that you can find for around $15 on Amazon. Held like a remote, it's a mouse; hold it sideways if you need to type. I leave the TV's volume always on max, and control the audio thru the TV stick.

It's slick, it's easy, it's cheap, and very efficient, and doesn't require *any* expensive hardware nor any cable running.

Being an astrophysicist doesn't make you at all qualified to use a VCR. (Wait, who uses VCRs anymore?! I haven't touched one in almost two decades!) But it *does* mean that we're not talking about an idiot. And if you're trying to target your product to be usable for the average joe, and an astrophysicist can't figure it out, you can assume that you missed your target.

Comment Re:Not an AMD CPU (Score 1) 57 57

I'm bully on ARM, with the (almost) collapse of AMD as a "first rate" processor, it's good to see Intel get some serious competition in a significant market space.

My only beef with ARM is that comparing CPUs is harder than comparing video cards! the ARM space is so fragmented with licensed cores and seemly random numbers indicating the "version" that I have no idea how, for example, a SnapDragon 808 processor compares to a Cortex A9 or an Apple A7.

Really, I'm lost. But the $40 TV stick with the 4x core A9 works pretty well...

I am amaze.

I had Windows Vista up on a (then rather beefy) 3-core 64B Athlon with 3 GB of RAM. IT WAS A DOG. Figure several minutes until it was responsive on boot, etc. Double-click a program and wait for the icon to blink, etc.

Upgrading the machine to Windows 7 without changing *anything* and it was like a new computer! It booted much faster, programs launched quickly enough that the coffee maker started to feel abandoned.

And it was *always* that slow, it wasn't due to malware.

You can blame the people as much as you like, but failing to consider the power of the media (aka Faux News, CNN, etc) is folly.

I wonder how much of that "ignoramus effect" is due to people actively being spoon fed garbage information?

Watching commentary on any news network is a veritable "here's how" for logical fallacies.

Comment I prefer Google TV! (Score 4, Informative) 133 133

Chromecast all but requires another smart device running (continuously) to control it. You can't control it directly.

Google TV, on the other hand, AKA "Android TV Sticks", are a full-on Android device, just like your phone or tablet, but without the screen. You control it with something like a mouse/keyboard.

You can turn off your phone/laptop while using a Google TV. You can browse the Internet on your Google TV, without using anything else to help. You can plug in a keyboard/mouse and use it like a computer! You buy apps on it from Google play, just like any other android device, and it's very compatible!

I just loved my first TV stick that I bought on Amazon (MK808b) for $35! I just bought an MK809 when my MK808b finally died after 3 or 4 years of daily use, and it has (so far) been a nice upgrade. Faster processor, better wifi reception, more memory/storage. Still runs just fine off the power from the USB port on the side of my TV...

PS: To control one of these, you want a "flying mouse remote". It's a keyboard that "mouses" by waving it in the air.

Comment Warning: DO NOT USE SAMSUNG SSDs IN LINUX SERVERS (Score 5, Informative) 195 195

We've been using Samsung drives in "non production" status servers, embedded servers, etc. and have had a terrible time of it. The first drives we bought a few years ago (840 Pro) were good, but we've seen Samsung SSDs run entirely through their write capacity (as reported by SMART) and then go dead when not even mounted! Turns out we aren't the only ones to get bit by buggy Samsung drives.

It also turns out that Samsung drives are even blacklisted in the Linux Kernel

I welcome Samsung's excellent cost/size value proposition! I just wish their drives were solid enough for our actual use.

Comment Re:Give me battery or give me death (Score 1) 134 134

My current laptop, a Dell Precision M3800 has it all: light weight, powerful, reasonable (if not fantastic) battery life, 4K screen, and native support for Linux, out of the box but it's hard to figure out what something the same size would be like at 1/4 the weight.

But I'm agreeing with other comments: I'd rather have this exact weight laptop with 3 days of battery life.

A few years back, I bought the phone with the very best battery life and I don't regret it one minute. Now on its third year, the phone still easily powers through a day with 50% or so battery life, and never leaves me high and dry when flying commercially which is when battery life is most important.

My next phone will be the phone with the best battery life Now that I finally have a powerful laptop that isn't also dreadfully heavy, battery life will once again be #1 for my next purchase.
