They had computers during WWII, they used them to break the german encryption.
They appeared in planes not too long after:
See: http://en.wikipedia.org/wiki/Fly-by-wire
***
The first non-experimental aircraft that was designed and flown (in 1958) with
a fly-by-
wire flight control system was the Avro Canada CF-105 Arrow[1],^{[5][2][6][3]}
a feat
not repeated with a production aircraft until Concorde[4] in 1969. This system
also
included solid-state components and system redundancy, was designed to be
integrated with a computerised navigation and automatic search and track radar,
was
flyable from ground control with data uplink and downlink, and provided
artificial feel
(feedback) to the pilot.
***
Also:
https://airandspace.si.edu/exhibitions/america-by-air/online/jetage/jetage17.cfm
***
The first autopilots were used on airliners in the mid-1930s. In the late
1950s,
electronic computers became small enough to be used aboard aircraft.
Sophisticated
digital computers can now fly aircraft in virtually any situation, while
ensuring that all
systems are functioning properly.
***
M$ Windoze. Yuck! I wouldn't put that stuff on my rig.
I do, for a few programs that aren't available on Linux (yet).
The flightsim for RC model planes is one of them.

[gentoo-user] upgrading to systemd 214 a disaster
After upgrading to systemd 214, my system would not shut down using the shutdown command, it complained timeout while opening/writing /dev/initctl . The power button shut it down, but it would not boot, the last line just said switch to clock source tsc and the system hung. Downgrading to 212 restored things. -- Your life is like a penny.

Re: [gentoo-user] systemd warning kernel 3.10 required

I can't go to that now, what might break? The README from systemd still says that you need 3.8 [1] (3.0 without some features); also, in the mailing list there was some discussions about some stuff being fixed so 3.8 remained the lower bound. sources.g.o seems to be down, so I can't see the ebuild, but I don't know of any strong reason to demand 3.10. I think they were waiting for the kdbus kernel inclusion to depend on it. systemd-214 fails to build with linux-headers-3.10. Upstream claims to support earlier kernels, but has been rather bad about testing them.

The key is that * I'm exporting more than one different (sub-)directories on the same filesystem * For some reason it gets confused with the uuid/fsid; Can't find the page where I found that anymore :-( * the actual device the exported filesystem resides on is /dev/md127 and not /dev/md0 as I originally wanted. Since I did not regard the number, I ignored this fact, but I also found hints that this might cause the problem of the previous point. The suggested solution was to add a *unique* fsid=xx entry to the exports file for each directory exported, so that it looks like: /etc/exports: /datadisk/music 192.168.1.0/24(rw,no_subtree_check,fsid=1) /datadisk/video 192.168.1.0/24(rw,no_subtree_check,fsid=2) /datadisk/backup192.168.1.0/24(ro,no_subtree_check,fsid=3) ... If the same fsid is used more than once then the first directory with this fsid will be mounted! So using *different* fsids for each exported directory is essential!!! So, my NFS works now as it should! Thanks to all who spent a thought on it! Alex

Ah, now I get it.
By definition random means that the probability for every value should be
the same. So if you have 62 options and even distribution of probability
the probability for each of them is 1/62.
Still, the increased probability for single elements should hit different
elements each time. So for large sets it will distribute - however, I now
get why it's not completely random by definition.
Usually when you need random data the quality needs to be good! Key,
passwords etc. For example if an attacker knows that your random number
generator same or the next index with double probability, he will most
likely crack each character with half the tries. So for each character
in your password the time is split in half. Again 8 character password
becomes 2^8 times easier to break compared to truely random data. This
is just an example though.
Try counting how of often new_index = index and new_index = (index + 1) %
62 and new_index = (index + 2) % 62. With your algorithm the last one
should be significantly less then the first two in large sample.
I will try that. It looks like a good approach.
Ok. I wrote a little library that takes random data and mathematically
accurately splits it into wanted data. It is attached to the mail. You
only need to specify the random source and the maximum number you wish
to see in your set. So with 5 you get everything from 0 to 5 (in total
of 6 elements). The library takes care of buffering. And most
importantly keeps probabilities equal :)

As you already said, nobody knows with 100% certainty. In the failures I've experienced I'd expect it to start catching errors within a few days. However, on those drives the relocated sector count never increases, which suggests that the firmware never relocated those sectors when overwritten, which seems brain-dead to me. If the drive relocates the sectors, then conceivably it could go quite a long time until having errors, probably in an entirely different set of sectors. Even if it doesn't relocate, the reliability of the bad sectors could be high or low. Rich What triggers a relocation? I also have a drive which shows a sector relocation pending, but for a few days now and after some tests that showed no errors, it won't relocate it. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
