Sorry, completely irrelevant: I didn't notice it's Bell Canada, so U.S. laws don't matter.

I have no doubt there's some US ISP doing the same thing :-(

IANAL.

I originally thought this was breaking 18 U.S.C. Chapter 119, 2510 to 2522 (?), but no.

*IF* they only alter the answer of their own DNS servers to their clients, when the client has made a request to said DNS servers, then they're probably in the clear. There is two communications: one from the client (C) to the Bell server (B), then one from B to the authoritative server (S). S then answer NXDOMAIN to B, which then returns a completely different information to C. So they're not intercepting anything.

OTOH, *IF* they hijack all the port 53 requests to the outside world (which I doubt), then it's very likely 2511(1)(a) and (d) applies. They still could argue under 2511(2)(a)(i) that it's "necessary"...

Then again, IANAL.

OTOH, even if it's legal, it's still absolutely wrong.

Distributed.net Finds Optimal 25-Mark Golomb Ruler 265

kpearson writes "Distributed.net's 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."

Comment Re:T2 on Demand? (Score 1) 236

Unfortunately no I'm not saying that :-)

First there's a typo ; the basic ML555 is $2200, not $1200.

Someone managed to synthesize a S1 (single-core T1, with multithreads support) for a Virtex 4 LX60. You might be able to squeeze a S1 into the Virtex 5 LX50T of the ML555, but I'm not certain, it mght be a bit short on available slices. Beside, it seems that they didn't go any further than that, and didn't actually try to upload the bitsream, let alone boot an OS. All that is assuming either the synthesized HDL included all required bits beyond the CPU to do so, such as a memory controller to access the on-board SO-DIMM and what-not, or that there's enough room on the FPGA to accomodate said bits. And that you have the IP of those bits, of course.

Then the T2 will probably be larger, even scaled down to an hypothetical single-core S2. I seriously doubt than you'll be able to squeeze a fully bootable S2 system in less than a V4 LX160. A PCI(-e,-X) board with one of those and some memory for your OS & stuff will probably be way over $3000. That's not counting the software tools, as free version of the tools are limited to the smaller devices, and the already mentioned IP that might be necessary...

Plus, you'll need the skills to bolt all the HDL, software and tools parts together.

It's likely doable, but at a very high cost in both money & time.

Research Reveals Mislaid Microprocessor Megahertz 99

SlashRating©
6*10^23

ransom1982 noted a new article on The Register that says "Not only are chip companies regularly releasing ever-faster microprocessors, but new research has revealed that modern CPUs actually lose megahertz over time." This makes it even more complicated to compare the performance of Intel and AMD CPUs since you have differing architecture, clockspeeds AND the year of manufacture to consider. Buyer beware!
