I think the largest PNG file that I've been aware of was under 500KB.

I'm sure i've seen bigger.

A 1080p frame in uncompressed RGB is about 6MB. Afaict PNG gets of the order of a 3x ratio on photographic data so we are probablly talking a couple of megs of png if someone lifts a frame from a 1080p video.

You should be able to download that in less than 1/6th of a second with 24mb.

Unfortunately the intenet architecture doesn't handle short connections well. The TCP/IP stack doesn't know what the available bandwidth is so it has to be conservative initially. On high bandwidth but also high latency connections (e.g. user in europe, server in the USA or vice-versa) it often doesn't reach the full speed available before the transfer is over.

I just took a screenshot of my dual-monitor desktop and it was about 125KB. And that's just saving it with MS-Paint

This is pretty meaningless without knowing what was on the desktop at the time.

In the early days of google+ there were reports of people losing their entire google account (not just google+) for signing up to google+ under something other than their real name. I can see why people would be reluctant to take that risk (however slight) with their main google account (throwaway accounts are another matter).

Comment Re:What's the big deal about win8? (Score 1) 346

I guess a lot of people here have Win8 forced upon them by external circumstances, which tends to put everyone in a sour mood.

Yeah, you want/need a newer version of the core stuff and you get a new and supposedly improved GUI shoved down your throat.

It's hardly unique to windows, look at all the gnome2 users who got gnome3 shoved down their throat when they updated to to the new release of their linux distros.

How small is small?

Once you go up to mini-itx there are loads of options but I sense that is rather bigger than you want to be.

The utilite standard and pro models (but not the value model) have dual ethernet but they are kinda pricy. Theres various hackable routers but they tend to be rather lacking in CPU power and storage (they make a Pi look postively high end by comparision)

The other option is to use an external USB ethernet adaptor.

Comment Re:What has a DMV got to do with draft notices? (Score 1) 205

AIUI (I don't live in the US so their may be errors in this)

To issue notices to register for the draft (there is no draft in the US at the moment but registration is still required in case there is one) you need two things, firstly a list of people with their addresses, secondly a list of people who have already registered for the draft. Then they can take the people who are in the first list and not in the second list and send them notices.

So the question becomes where to get that list, why the DMV well it's kinda simple.

1: most people drive and hence are issued driving licenses by their state's DMV
2: driving licenses are used as ID cards
3: you have a minority of people who don't drive, these people nevertheless need some kind of ID card, the states decided that it was simpler to have the DMV issue ID cards to people even if they don't drive than to set up a separate ID card department.

So the DMV database is the closest thing to a "database of all people in the state" that is readily available.

Comment Re:Huh? This info was in a live database? (Score 1) 205

AIUI they used the DMV (driver registration) database to send out these reminders. Is it really that surprising that someone born in the 1890s could have been driving up to say the 1980s and have active records in the driving license database continuing into the 1990s and 2000s?

Comment Re:What might have happened. (Score 1) 205

One scenario: some systems have tables that use a separate field for storing the century.

Why do you think they have that field? Why would someone design a database that is less efficient and encourages wrong queries?

Most likely because someone previously fucked up and thought 2-digit years would be enough, by the time they realised they needed to fix that it was easier to add a new field than change the semantics of an existing one. Given that how accurate do you expect the data in the centuary field to be for old records?

and in some databases they didn't even go as far as adding a century field instead just assuming that 2 digit years represented dates in a window arround the current date.

I'm sure people said the same about fly by wire when it was first suggested.

Yes it will likely take many years of experimentation, risk calculation, arguments with regulators and so-on to turn this from a concept into an actual product but I don't see any reason why it couldn't be delivered at an acceptable risk level.

Comment Re: Failsafe? (Score 1) 468

Yes there is some risk of a total hydraulic or electrical failure but nevertheless the benefits from having larger planes than are practical with manual flight controls were deemed to outweigh those risks. Similarly the benefits from having a stronger more aerodynamic airframe and better visibility under normal conditions may be deemed to outweigh the risks of total camera system failure combined with a situation that prevents landing on instruments or a hazard that can only be spotted visually.

You will never reduce the risk of flying to zero, there always has to be some balance.

Comment Re:Is it really a single board computer? (Score 1) 122

The documentation for using the module on your own board is available from the B2B section of their site. The connectors are off the shelf parts from hirose.

However while desinging and making a carrier for this will be much easier than designing with the imx6 directly it's going to be beyond most hobbyists. The connectors have a pin spacing of 0.4mm and massive numbers of pins.
