Comment Lipos are dangerous. But they are also tough. (Score 1) 89

I strap propellers to 1300mah lipos and drain them at rates exceeding 100amps. I will drain said Lipo in approximately 180 seconds. Sometimes less. And when they land they are often exceeding 60c.

Not only that but I will often slam them into hard surfaces, trees, rocks, or pieces of plastic that are rotating at 30,000 rpm +. Despite this I have yet to have a single one spontaneously go up in flames. I have seen the after effects of over charging lipos when people decided to charge them to too high a voltage or charge them too fast. But if you treat them inside their design specs they are very unlikely to ever cause you a problem.

I believe Niantic have about 30 employees. Those employees will predominately be developers of their various games and skilled in that type of work. What they are probably not very good at is detailed data analytics.

So what do you do if you're a business and you need a skillset and toolset that you don't have and you need? You hire another business that provides the skillset and toolset that you need. Just like hiring a plumber.

So I don't read this as them giving the data away at all. I read this as "we need to know something but don't know how to get that from our data, so lets get XYZ company in to help"

It's an internal business transaction so it would vary from company to company. Most likely though there was an attachment to the email which would be a form of some kind. If that form was completed properly there would be limited reason to not perform the transaction.

On top of that $40m is not a large amount of money to transfer in 1 go. Especially not in a manufacturing environment.

If the videos have been processed to h.264 or h.265 then yes you will see almost no improvement at all. In fact your files will most likely be larger.

However that wasn't the premise I was basing it on. I was basing it on uncompressed mpegs or avi's taken straight off the recording device. That is certainly what I use for my home videos and it wouldn't make sense to process them into something like 264 as it makes them a huge pain to work with in video editing software. I also made an assumption, I know mother of all fuckups, that if he has 2tb of photos they are most likely in RAW. Otherwise that is a whole lot of photos as the OP doesn't mention video at all.....

Comment Re:Tape backup - (Score 1) 366

LTO almost always achieves a 2:1 compression using SLDC unless the data is pre-compressed or particularly random resulting in no compression. For the purposes of photos or video a 2:1 ration would be a safe assumption to use.

LTOs will read their own generation and the tapes of 3 previous generations. They will also write to their own and the previous generation of tapes. It is this strict adherence to a standard which makes them such great backup options.

I don't understand what you mean about drives with 1 digit indicator? Given HP and IBM are both primary contributors to the LTO project and have access to the same materials I don't see much in the way of difference.

Go onto ebay and buy an 2nd hand LTO3 or LTO4 tape drive for $150 - $300. Plug it in, write your files to the tape. For 2tb you would need 3 LTO3 tapes (assuming compression 800gb each). Take said tapes and drive them to another house.

Decide what timeframe of loss is acceptable. ie 4 weeks, 4 months, 12 months. That is you maximum backup cycle time. Every X period of time take a new set of tapes to your offsite backup location. Buy tapes equal to at least 3 full cycles, that way on your third backup trip you take the oldest set home and re-use them.

This is the process I use every 3 months and I have an HP Ultrium 960 sitting on top of my NAS. I also use your normal google drive type backup, but it is my second stage, rather than first stage backup. I'm not quite at the same size as you, 1.1tb, so it's 2 tapes not 3. I bought a box of 50 new lto3 tapes for $100.

Because just maybe it could save someone. Because the person buried under the rubble was playing pokemon go and carrying at 16000mah battery pack. Because maybe the person has been turning their phone on for 5 minutes then turning it off when they have no signal. Because maybe the emergency workers in you area might be able to use it to communicate back to base where as for what ever other reason they couldn't have.

I mean seriously? Why wouldn't you? I've read a heap of the comments about how insane you would have to be and all the legal risk you would be at but we're not talking about leaving it permanently unsecured, we are talking about a short period of time during a national emergency where people around you are buried under collapsed buildings!!

Christ I get it, you have you NAS full of your super sensitive material, well turn the fucking thing off then. This is slashdot ffs, are you seriously telling me that you don't have the capability to turn off a computer you don't want someone to access?

People are dying, infrastructure has been damaged. Who knows what state their mobile network is in, perhaps it's not possible to bring in wifi hotspots.

The chances that if all people unsecure their wifis that your connection will even get used is pretty small. The chances yours gets used by a malicious actor is vanishingly small. The chances that your open wifi saves a life is also tiny, however it might. So I just don't get why someone wouldn't be willing to take on a little, essentially insignificant, risk if it might save someone.

If an earthquake or similar disaster happens near me, not only would I happily open my network, but I would be out there trying to physically help people, so I could just turn everything off for a couple of days as I'm not using it. Maybe I'm the strange one.

Comment Re:How does that work? (Score 1) 106

I think you are getting into the semantics of what is legal and what isn't there. I get it that you feel that the constitution should be the basis of all laws and powers of the government but it isn't and hasn't been for a long time. Laws and legislation are passed by the government because they have the power to pass them and enforce them, and while there is always the risk of civil uprising that is no different then if the rule causing an issue was written into the constitution.

Most other countries don't have a constitution that has as many explicit clauses as the US one, and some, such as England, don't even have one. So a constitution per se is not inherently more legally binding than anything else simply because its a constitution.
