USB isn't built for juggling machines. Every time you switch from Machine #1 to Machine #2, the USB devices all magically vanish and disconnect from Machine #1 (prompting drivers to be disabled), and magically reappear on Machine #2 (drivers now have to be loaded and initialized).

Good KVMs show up as a composite HID device and always present that to the OS, even if a different computer is now active. One of the things this means is that most gaming mice and some keyboard keys aren't passed through.

Really good KVMs have an option to disable this feature and allow straight pass through of the devices to allow all functionality.

Much like the movie, it's all about the energy source, the mechanics are a solved problem already.

The mechanics of how to keep a man from being turned to jelly when the suit gets tossed into a nearby building by the Hulk have been solved?

Seriously, though, there will never be an exoskeleton as maneuverable and fast as the Iron Man suit, since there is no way to protect the occupant from mistakes that cause sudden deceleration. Even a fast turn could be deadly.

I have nothing against the modern-day Volkswagen Group, but to deny its corporate history (and that of Mitsubishi, Daimler-Benz, Fujitsu, etc.) is no better than a Nazi tactic.

I always thought that Mitsubishi should start using the tagline "From the company that brought you Pearl Harbor".

Comment Re:10 Mbits isn't enough (Score 1) 280

Because a business that wants to get guaranteed 50Mbps will easily pay $1000/month or more.

Consumer broadband works by splitting that among several people, so they pay for a share and as long as no one hogs it all, they can also share it.

I pay about $120/month for 35/35 business service...it would be about $150 for 50/50, with as much "guarantee" as any provider will give you. As with all things broadband, it's all about competition. If there's a lot, it's priced as it should be...otherwise, $1000/month for 50Mbps is what you get.

Like the THEMIS Day IR 100m Global Mosaic torrent, at 42GB is streamed? Or the Internet Census 2012 at 569.43GB? Torrents are not just movies - there are some really interesting public domain datasets out there.

But, that's nowhere near normal use case. I download torrents like that for my work, and 500GB is just a starting point. My current project has 245 files larger than 500GB, going up to 917GB (total data about 2.6PB).

I wouldn't expect anybody to download this stuff to their home connection...I use about 2-3Gbps for the download, and we only had a 10Gbps connection total for over 4000 users...luckily that's now 100Gbps.

Comment Re:10 Mbps (Score 1) 280

I tend to get frustrated with the speed gets below 100. This is particularly the case when downloading a Playstation game and you stare at that progress indicator waiting to play. :-) If I want to play, I want to play now, not in 30 minutes (games are big these days).

I only allocate 10Mbps to my Steam downloads, and it's not unusual for a game to take 10 hours to download (40GB games aren't unusual, as you say). Even with 100Mbps, it would take an hour and saturate the link.

If you want to play now, you're going to need at least 1Gbps...that 100Mbps isn't going to cut it.

I have 100Mbps (down). I don't run a porn server, however I do work from home frequently. All wired 1 GBps in the house, yes I really run a SAN. Being your judgmental and unhappy self, how would you rate my usage?

First, I run a 10Gbps backbone that my SAN and ESX hosts are connected to, and 1Gbps to all other locations. So, you're nothing special.

I have FiOS up to 500/500 available where I live, but only pay for 35/35 because other than the occasional game download, nothing takes so long that I even notice. I can play games, stream movies, remote desktop, etc., and it's hard to tell which sessions are local and which go out over the Internet.

Only with many, many popular torrents, and then you run into the problem that you need very fast disks to keep up with the 600MB/sec read+write. I work with a lot of systems that transfer a lot of data, and the trick is balancing all the hardware so it can all keep up with the speeds.

At my work, we're just installing a 100Gbps connection to the Internet, and all that means is that we now have to upgrade everything else to be able to take advantage of it.

Comment Re:They almost got it right (Score 1) 229

If you're keeping your connection near 100% utilized in both directions 24x7, frankly, you're not that kind of customer they want anyway, they'd just as soon you go bog down someone else's network (unless you're willing to actually pay more to offset it).

300 GB per month is 1 megabit per second average. So, even hitting 1200GB/month, you're not getting anywhere near "100% utilized" on a 10Mbps line.

I strongly suspect this very low number was picked because there will be quite a few people who will just bite the bullet and pay the extra $30/month, regardless of their actual usage.

In this fictitious example, DoD is paying Gmail for a proven email system and the personnel to keep it running, up to date, and secure.

The other huge difference in your example is that DoD would merely be paying for something already built and functional.

TFA is about three companies building a system from scratch. Even if they use something that mostly already exists, it will be highly customized for DoD, to the point that it will be different from anything they have already done, and nowhere near "proven" or "tested". Since the history of those three companies shows they want nothing more than keeping their clients locked in as long as possible, it's not a recipe for long-term success.

Comment Re:Two-factor auth. Buy some cheap Yubikeys (Score 3, Informative) 142

The Feds always look for the most expensive option. They'll end up with pricey battery powered hardware tokens when they could look at cheap Yubikeys.

Every employee of the US government already has two-factor authentication in the form of a smart card. The problem is that there are many programs that don't have the hooks for two-factor authentication built in.

For example, a web app that queries Active Directory almost always asks for username and password, when Windows Authentication can use either username/password or smart card/PIN. This is because smart card/PIN requires trusted code to run on the client computer, and we all know that isn't really possible.

Throw that same programmer into a FORTRAN, LISP, or eris forbid Prologue, and there will be a larger learning curve than just the syntax and limitations.

Modern FORTRAN won't be that big a deal for anyone familiar with C and bash. Same looping structures, free-form code (indent however you want), etc., but just no braces to mark blocks.

Comment Re:Upstart or Systemd? (Score 1) 494

Systemd has mount unit files that can specify before and after dependencies so I can tell it I want it to load after the network and daemons they depend on but before things like ftp, apache etc.

When this works, it's great, but when even mounting NFS (what used to be quite a simple thing) can cause the system to hang because of errors, it's not really a step forward.

On previous init systems, if your NFS mount wasn't available before the subsystem that needed it, then that subsystem might not start up correctly, but the system would finish booting and give you a login prompt A little tweak to a startup script to add a check and the problem is solved for the next boot, with only a little time when the service isn't available (after a manual start). But, I've seen systemd just stop the boot process when it can't fulfill a dependency like this, and the only solution was to reboot into single user mode, tweak config files, and try the boot again.
