How To Steal a Space Shuttle
Perhaps the security is adequate if that is the best plan.
Security is not about making absolutely sure, it's about:
1. Lowering likelyhood: Making it reasonably hard to break, so that the bad guys will go somehere else.
2. Spend wisely: Not spending more to defend that the likelyhood of loss times (value lost + value bad guys gain) (in general terms)
a. Round up the likelyhood, the bad guys are better than you at getting ideas.
b. Destroy sensitive and remove generally valuable parts to reduce the bad guys value
c. The value lost is *not* the money spent on the lost property. Perhaps you wasted a small bit of effort making it? pehaps you can recreate new and better cheaper?
I think the value of the space-shuttle is mainly sentimental and image-loss on theft, so you should probably not spend more than a simple escort -- mainly to prevent traffic-problems.
I go through keyboards ...
Im guessing you have a diNovo edge? Run the following as root:
# fix hiddev to hidraw in BT rules and put it where updates dont overwrite
for x in /lib/udev/rules.d/*-bluetooth-hid2hci.rules;
do sed -e 's/KERNEL=="hiddev/KERNEL="hidraw/' \
<"$x" >/etc/udev.d/rules.d/$(basename "$x");
# restart udev
service udev restart
It even work if "they" change the numbering again :) (like from 62 to 97 :)
Ask Slashdot: Best Programs To Learn From?
Look at the libstdc++ for GCC and some of the boost project code.
That code has production quality, is written in a style that actually utilizes c++. Beware that c++ recently got quite a few new features that have not gotten too much usage in libstdc++ and boot you may want to read up on that separately.
There is an *excellent* FAQ on most of the fine-grained aspects of c++ at http://www.parashift.com/c++-faq-lite/
In general, stay away from tutorials on the web, they are mostly written by people who have little or no experience and thinks they should teach the world about for loops or whatever because they just made one that doesn't crash themselves.
Court Filing On How 2004 Ohio Election Hacked
I always kinda liked this saying by WC:
“You can always count on Americans to do the right thing - after they've tried everything else.” -- Winston Churchhill
(Actually, it applies in other places too :)
The Clock Is Ticking On Encryption
Today, quantum computers are *very* limited in size. The number 15 has been succesfully factored into the primes 3 and 5.
There is no really promising ways to produce large amounts (~1000) qbits. I strongly suspect that the difficulty in generating qbits is (at least) exponential in the amount of qbits to produce.
qbits cannot be composed after they creation (at least with known physics), so I am definatly *not* holding my breath for quantum computers to break RSA-2048 or AES256.
When RSA is broken (when it takes less than a few hundred years on average to find a secret key), we already have multiple other crypto-systems ready. Elliptic versions of RSA are *already* part of standard-implementations in browsers and they shift the amount of qbits required with several orders of magnitude (with known math).
Which Breakthrough Is Most Likely?
I believe that teleportation *could* be possible, although it would not be "teleportation" as much as "teleduplication". However, you just need to:
* A. Create a molecular constructor for the tele-"portation"
* B. Create a mechanism for "snap-shotting" the state of all atoms in a human body. (rougly a count of 7*10^27)
* C. use some way of transmitting massive amounts of information FTL.
C is certainly possible, but then known methods have problems. Causality is actually preserved in them so the infomation available when you decide to transmit your information is limited.
Have you ever read anything non-sci-fi about wormholes? It's not like people would fit in -- and especially not like they would come out in any kind of configuration like they went in.
Hyperdrive. It is just a word -- used by sci-fi to suggest FTL-travel. If you had some matter with negative mass, and some means to control/move it you could distort space-time to allow FTL-travel but I'm not holding my breath for either of those requirements.
As for positions "suddenly changing" -- what are you talking about? Bodies that can be said to have postitions don't "suddenly" move. There is not even any evidence of any quantum on time, so -- at least for now -- you should think of all movement as continuous.
Which Breakthrough Is Most Likely?
Which Breakthrough Is Most Likely?
Time Travel: Not with a detectable effect, and certainly not for anything human-sized. The arrow of time may be relative but it's certainly not reversible on a macro-scale.
Faster than Light Travel: How would that occur? *Every* experiment shows that FLT would require infinite energy for classical bodies. For sizes where quantum-theory apply it's more complicated but doesn't concern physical presence. If you had a programmable molecular-replicator maybe :)
Human-level AI: Well, possibly... but only by dumb-luck. Which is weird since "human-level" is really not that high.
Discovery of Aliens: Well, that is mostly random.
Immortality: Naaaah..... not really likely to work on complicated systems like a human body. Not for "eternity" anyway -- maybe for long but not forever... and not as in "cannot be killed".
World Peace: How would that come about? only if there was nothing to fight for -- meaning total extinction.
Nah, fetch me some duct-tape, a laser and a shark and i'll show you what comes first.
10th Annual System Administrator Appreciation Day
Perhaps people do not appreciate what their sysadmins do because the sysadmin is not helping but hindering them?
My best experience ever with sysadmins was at DAIMI (now Department of Computer Science) at the University of Aarhus, Denmark. Perhaps you can compare what you do to them?
They ran by the priciple of freedom under responsibility (traced, of couser :) The system was not down for any annoying period of time while I was there.
- Incredibly service-minded,
- Running stuf was allow-by-default, of course this was UNIX, so you could mostly trash your own stuff :)
- Active logging of who spawned what and used how much CPU/disk/net, and an email asking why when you were outside the norm
- Limited disk-quatas, but you could simply extend your own quota by running a command and giving a reason, the space was immediatly awarded to you for use -- if the reason was not good enough they would email you
- Allowed most anything as long as it didn't interfere with the other peoples ability to use the system.
US Government to Have Only 50 Gateways
The "gateway" methodology splits the world into inside and outside, not a usefull split, since there are *always* bad guys on the inside.
However, it nicely ensures that spendings on hosting and applications is filtered through a limited number of suppliers, reducing competition and stifling innovation -- the american way ;)
