You hit the nail on the head: the problem is power/weight. Looking at the specs http://www.parrot.com/parrot-ar-drone/en/how-does-it-work#start/ it looks like the batteries are expensive lithium-ion-polymer with "15 minutes battery autonomy", which I assume is a fancy way of saying that you get 15 minutes run flying time between recharging.
Hey, Mr. "this was sent from an Alpha" himself! I remember you well from comp.os.vms in '89 thru '93 and a bit later, I used to lurk in that newsgroup daily. I still remember some of the (in)famous DCL scripts you posted that generated hundreds of replies in controversy. But this is not the time or place for such reminisces...
I'd agree with you that OpenBSD will probably never be a winner in any of those categories you listed, but I am still a (mild) fan nonetheless if not for any other reason than for evolutionary diversity. OpenBSD may never become mainstream but some of the code that the OBSD team work on often filter back to the rest of the open source community. Especially the code auditing they do for Apache and other key ports.
VMS is slower than OpenBSD on a comparable system? I haven't tried OpenBSD on Alpha but if you have run OpenBSD/alpha and OpenVMS on the same or similar Alpha server then well done sir, and do you have any metrics to show us?
The problem I have with your statement comparing (default) filesystem for each OS is that they have quite different feature-sets, for instance VMS has file-versioning, and quite extensive access control and access auditing capability. Bash is a very lightweight and simple shell that relies on a lot of (admittedly) standard Unix tools (such as grep, awk, sed, etc) to make it useful. DCL on the other hand has a significant payload of lexical functions. VMS has a batch and printer control system that is leaves unix job and print control way behind, VMS is more akin to a traditional mainframe in that respect. So don't get me wrong, I'm not knocking OpenBSD (I'm a great fan of the secure-by-default nature of OpenBSD) but I just don't believe one can easily compare it to OpenVMS...
Obligatory mention of The Manga Guide to Statistics - see Slashdot review: http://books.slashdot.org/article.pl?sid=08%2F12%2F15%2F1432233&from=rss/... although perhaps that is because the book didn't get a very good review, not to mention that the discussion that followed the review article wasn't very, er, academic... and maybe the book is more suitable for 15 year olds rather than 16-18 year olds... Oh well...
The Arm interests me, at a hobbyist level, but I've been unable to find an affordable development board that could then be used for small scale production, say 100 units. The reference designs seem to imply that one would design their own board and have them manufactured on a large scale... The 8 bit boards on the other hand are cheap enough for a hobbyist to play with. But then by the time you add video output module, ethernet module, and perhaps usb or wireless modules, the price has ramped up again...
Your link to Luminary Micro are interesting and useful, but they are still out of my price range:-(
Although the first thing that came to my mind when reading this was "what a pity that Philip K. Dick isn't alive today to see truth slowly but surely becoming stranger than fiction..."
According to the Guest OS compatibility table, FreeBSD 6.2 is supported on VMWare Workstation 6.0.2 and VMWare ACE 2.0.2
Having said that, VMWare guest is running on a fairly standard sort of virtualised platform. With VMWare ESX 3.5 you can use a Buslogic virtual scsi controller or an LSI virtual scsi controller. So you may have to do some fiddling to get FreeBSD to load the appropriate device driver (don't ask me how, I've only ever done generic installs of FreeBSD)
VMWare ESX Server 3.5 will (officially) support:
* Ubuntu Linux 7.04
* Solaris 10 for x86
* Suze Linux Enterprise Server 10
* Redhat Enterprise Linux 5 and various other OSs...
I've been using ESX 3.5 on an HP DL385 G2 with dual core Opterons and 8GB of RAM, I wonder if that is powerful enough to run Vista as a guest OS...:-)
This question probably won't be relevant to US users, but is more directed to anyone in the UK, Europe, Australia, or NZ...
I tried out MythTV some time ago and tried to get it to record Teletext subtitles with the program, and failed miserably, mainly due to my lack of ability, more than anything else.
Can anyone tell me if MythTV now has built-in support for recording Teletext Subtitles?
And my favourite visualisation of this can be found in the http://www.astro.princeton.edu/~mjuric/universe/ Logarithmic Maps of the Universe page.
I get a kick out of it every time I look at this map - it still blows my mind! It is amazing how insignificant our planet is, when you consider the number of galaxys (let alone stars) there are in the universe...
How's your powerbill? I last time I checked, my local power co charges me 15.3 cents (NZ$) per KiloWatt/Hour! I'm guessing your KW/H rate is a bit less, right?
What innovation?? OpenVMS has had this for decades...
Recalling from memory the last hundred or so security patches released by MS for Windows 2000 in the last few years, I'd hazard that about 75% of the holes were buffer-overflow patches. That still leaves a lot of other vulnerabilities.
Follow the link Dahan just gave you: http://www.tru64unix.compaq.com/noncommercia l-unix/
for the hobbyist Tru64 licenses.
But, who needs Tru64 when there is VMS? If you want to try out a public access VMS account on the Internet, check out the "Deathrow" cluster (yup, VMS had true clustering decades before Micrsoft claimed to be able to do it) at: http://deathrow.vistech.net/

This review [IT Week] mentions that the technology has been licensed to Motorola, Siements, Nokia, and Microsoft, and first products will ship and the end of this year...
The Sybase heart got torn out with version 7.0 of Microsoft SQL Server. Version 7 is 98% Microsoft code. Version 7.0 (and also SQL 2000) is actually quite impressive, but so it should be with the number of PhDs that Microsoft brought into the SQL development group...
Of all the M$ products, I think that SQL Server 7.0+ is their finest creation. Exchange Server, on the other hand, is worthless crud written by people who wouldn't know an RFC was if it slapped them in their faces with a wet fish...
Opera 5.0 (which is now free, kinda) can keep you well informed about 3rd party cookies too. And at ~2megs, its a lot quicker to download than IE5.5...
