I had a situation that appeared that a hacker had taken control of a VOIP system and ran up a full E1 worth of calls to Africa 24x7 for a weekend resulting in a $1.4 million dollar phone bill. The initial evidence showed that Sierra Leone was involved with toll sharing fraud but I looked deeper. I called a few of their embassies and found out they couldn't call home if they tried and the London embassy had some who had the job of trying to calling home all day. It turns out that someone else was playing the scam and taking the money. Sierra Leone was given millions every month for the scam but then it was taken way with fines leaving them with problems. Everyone I talked to was hesitant to talk to me until I explained that I didn't think they were the scammers. I ended up talking to Alpha (what a cool name) who was the head of their phone company and he provided just the extra details. I had a friend from The old school US telco get some of the guys who used to work in the dark room listen to the calls and they said the wobble in the busy wasn't right for modern automatic gear so calls there would be considered connected even if most people heard a busy signal. The end result was a US phone company shipped them a nice bit of kit to terminate some of their calls in a deterministic way.
The stones I saw in the Great Pyramids that looked like they came from the same area, were in the same orientation and I expect rolling them would leave about half of them upside down from their neighbours.
I think most archeologist have incorrectly lumped Engineers in with Scribes.
I think the great Pyramids were built on their North and West sides and I think the different chambers were in the center at different stages of construction. If also solves the problems that you don't know how long you have to build a pyramid if it needs to be that shape for your ritual and there needs to be a chamber in the middle and bigger is better.
Herodotus said they used wood devices to lift the stones. I've seen pressure points from logs under the edges of the casing stones on the Red Pyramid but the internal and casing stones were done differently than the core stones. Wood has been rare in that area for very long so anything that wasn't needed anymore was firewood.
The boat they found buried has deep cuts on the deck as if someone had loaded up many several ton stone blocks on its deck. The sizes of the stones seems to decrease at height and I'm not sure how the 2.5 ton average came from and while it is everywhere, I question it. I don't think the casing stones were ever finished because if they were, there would be plenty of buildings in Cairo that had angled cuts in their stone work and I don't think any have been found.
I still don't think they later ones were ever intended for burial but just part of the process resurrection so if they Pharaoh didn't walk out, he wasn't God they were looking for and they tried again with the next one
The other key aspect that I wonder about is the fact that the Coptic religion managed to spread through out Egypt with minimal major political problems or wars which means the new religion was so close to the old one that it didn't matter or is was so radically different it blind sided an entire population.
Radio astronomers are look at pulsars a different way than a Galaxy Position System needs to.
The pulsar interference issues came up shortly after the industry found out that Trimble was making use of the short bit at the end of the message to figure out when a frame started on the military signal which gave them much better accuracy. The pulsar noise messes up the way that was found so it had to be filtered out and those filters helped clean up other noise issues. That was over 15 years ago and I haven't worked on this in over a decade.
I agree you need a large antenna if you want to see some of the finer detail of pulsars radio transmissions since they tend to have something in the range of 400 to 450 db signal loss. For a GPS system, you don't need that fine of detail, you just have to be able to compare the time between two pulsars which is a much simpler problem.
Most major GPS chip sets now actively filter pulsar noise. The thing about pulsars is they are better clocks than what is being launched and they transmit on all frequencies. The ephemeris calculations are much harder but it has be used to 2 meter accuracy and it isn't even limited to working just around earth. I wonder why they spent so much money to duplicate two existing systems that weren't even state of the art when they started. Maybe it was because you can't license pulsar transmissions.
I've been telling people that going to those odd top level domains are like calling 1-900 numbers, you will get a large bill from your ISP so just don't ever use them.
Microware OS9 running on a radio shack color computer in 1984 had module white listing. It used CRC but it was a step in the right direction. Too bad it took Microsoft decades to catch up.
You need about 700 meters of depth with the current off the shelf parts to make a RO well in the ocean. I think there is some technology that might let it work at 250 or so meters. You still have to pump the water up from that depth unless you can play games with building a saline density pump. Then there is the problem of changing a filter at depth.
Pedestrians are getting killed far more often at crossings at much higher rate than anytime in the past 60 or so years. The numbers they are seeing may not be related to what they think are seeing.
If Australia, Canada, Japan and South Korea got together, they could get the F-15 Silent Eagle built to the appropriate specs. It can be more stealthy than the F-35, it would be cheaper, faster, it is a proven air frame and it would meet the internal defense roles as well as the role of supporting allies. The F-15 Silent Eagle (or F15 Advanced as that might be its current name) is an more modern F-15E Strike Eagle air frame with modifications taken from the failed F-23 prototypes.
Seeding the random source using a private key looks like the same concept as using your encrypted root passwords to seed the TCP sequence numbers. This is not a new concept.
The limit of income is as low as $400 and as high as $22,000 for some retired couples. Anyone working and making in the range of $10k a year had better check http://www.irs.gov/publication...
When a hammer works, you don't get a new one just because there is a new one. Upgrades cost a fortune for most businesses and upgrades nearly always break some part of the business process. Most businesses have been burned by the upgrade process in the past and when they start putting a dollar figure on the upgrade vs the cost of not doing the upgrade, it is often cheaper to not do the upgrade.
Oddly enough, it wouldn't. You could use NAT hardware in front of old gear and everything will just keep working. Stuff that gets updated, could just use the new syntax and deal with things correctly. Stuff like core routers and switches wouldn't care. It would be fare less disruptive than trying to install ipv6.
I know a few people who have conspired to tell others that the nontraditional domains are like 1-900 phone numbers and when you use them, you will get a bill from your ISP.
Early ip resolver libraries would sometimes parse octal ip addresses with commas as in your example of/.'s ip address as 330,42,265,55. Many of those would also deal with a 0xd822b52d or sometimes without the 0x. Many systems will let you do something like "ifconfig en0 0xd822b52d/32 alias"
Some of the early proposals to expand the IPv4 address space was to allow use more of the bits from the ports source and destination addresses so you could do things like "ping 8.8.8.888" or "ifconfig en0 8.8.8.8/32/13/2 dstbits 4 srcbits 8"
Microware OS-9 from 1979 used program and modules somewhat like DLL or shared libraries. The code to load a module would CRC check them when loaded and that bit of code could check a list and that list could either allow or deny any module. If you loaded the right data module, you had built in white listing about 3 and a half decades ago.
I could still hear the Saturn V when the 1st stage dropped off. It had lovely base with a crackling. Figuring speed of sound, vs speed of light and wind and sound drop off over distance, I suspect this thing isn't that loud.
There is one disadvantage of the different ARM modes and that is the an arbitrary program will contain all the needed bit patters to make some useful code. This means that any reasonable large program will have enough code to support hacking techniques like Return Oriented Programming if another bug can be exploited. I would love to see some control bits that turn off the other modes.
If I compile from source, I can ensure that the binary I have is unlike any other in the world. That has protected my machines in the past so I will keep doing it.
Early Java was nothing other than a mess of pointers to pointers to pointers to pointers to more pointers all in a multi threaded system. The T1 addressed that problem but the concept of "All problems in computer science can be solved by another level of indirection*" is false and at some point compiler writers fix part of it. When they win, concepts like the T1 fail.
Sun tried great things with the T1 and it was like a great chess move that failed. The problem is they did a pawn sacrifice of their core business for that attack and it just didn't work out. Up until the T2000, Sun never designed their high end kit, they stayed with the low end and groups like Cray or SGI did their "big iron". The only great boxes sun designed in house where the small pizza boxes. The SS1, SSP20, x1, netra210 were great little servers. Things like the 690 and e10k were outsourced and while they were impressive as well, they didn't have the personality of the pizza boxes.
Have you read "man inittab" on any system V derived? action=respawn means it will ALWAYS run at the listed run levels. Sort of like how it runs the svc daemon does now. Whoever planned the new system just didn't get "init".
SMF only runs things as long as the contract system works.
As far as writing sensitive data to disks, do you know about the "real world?" Take a look at any online credit card system in the world. You will find people enter their card number as their email address, shipping address, reference number. You will find admins sending stuff like "can you fix 4111 1111.... 1111 for me?" SSNs flow like water as well. Some times you must scrub the empty space on the disk or scrub stuff you know was just wrong. ZFS has NO ability to do that and that is a MAJOR FLAW!!!!!
ifconfig isn't about the stack. It is a tool to tell the stack what to do and has been for more than 3 decades. Inventing new tools to do the same job was pure incompetence.

Years ago I had a counter scripts for the common scam script. Does anyone have a site with some that fit the current scams?
