Ask Slashdot: Can Bruce Schneier Be Trusted?

optikos Re:Trust no one (330 comments)

Applying the mantra of open source to the underlying mathematics: Learn the mathematics of cryptography yourself to find the bugs within the mathematics. Don't place your trust in any person other than yourself. Especially don't worship some brand-name as a god who, as diviner-intercessor, is your sole information-provider on the subject.

How Car Dealership Lobbyists Successfully Banned Tesla Motors From Texas

You obviously are not from Texas. When a small town in Texas has only one restaurant, it is a Dairy Queen, not a McDonalds.

How Car Dealership Lobbyists Successfully Banned Tesla Motors From Texas

optikos Re:Holy Fuck People! (688 comments)

In Texas, we are free to go buy any vehicle out-of-state (e.g., California) and import it into Texas via a Green Sheet and payment of the Use Tax (a.k.a. sales tax, but dodging the interstate commerce clause of the federal constitution). Once imported, the out-of-state vehicle can be sold at used-car lots, just like any other nonmilitary vehicle. Looks like a free-market to me.

Ask Slashdot: How To Get Open Source Projects To Take Our Money?

optikos Re:Try actually donating? (301 comments)

No, this company probably budgeted that $20,000 for expenditure for purchasing 'X', whereas the accounting department would not permit reallocating 1) monies dedicated for purchasing 'X' into 2) an entirely different bucket of monies for donations to section-503 nonprofits. Here X is likely right-to-use software. Perhaps X might be hardware. Either way, acquisition of a durable good gets amortized over multiple years, whereas the entire donation to section-503 nonprofits hits the books immediately.

A RAM drive for the modern age?

Yeah, it is called demand-paged virtual memory. RAM drives were useful only in primitive operating systems that lacked any form of virtual memory.

Could Humanity Really Build 'Elysium'?

optikos Re:The real question: self-fulfilling prophesy (545 comments)

If humanity (or even only the G20) were to ‘throw everything they have at it to build a space station of the scale of Elysium in 150 years’ then we would absolutely assure that “Earth is beyond repair”. Although not strictly a zero-sum game, economics & engineering are relatively inelastic at each plateau of history unless some paradigms seriously shift, lurching humanity to the next plateau until the next set of paradigm shifts:
1) numerous liquid-fluoride thorium reactors (or analogue) at each locality providing abundant power for pennies on the dollar, when compared to current energy storage, distribution, and consumption technologies;
2) inexpensive extraction of minerals deep below Earth's crust (or analogue) providing more resources than the sum total of all of human history;
3) rail-guns (or analogue) inexpensively allowing vast mass per payload to reach escape velocity;
infinity) and a bunch more paradigm shifts about which no person on the planet currently has the slightest inkling at all. Here the unit of measure of infinity is “bunches”—actually probably “bunches of bunches of bunches of ...” in depth & breadth.

Opinion: Apple Should Have Gone With Intel Instead of TSMC

If Intel has ceased be a foundry to 3rd-parties' custom silicon, then someone had better tell Intel's first foundry customer: Achronix FPGAs, currently the first 20nm FPGAs on the planet and on track to perhaps be the first 14nm FPGAs on the planet.

optikos OP is flawed: Open source is not a democracy. (406 comments)

Open source is Ayn Rand's 1949 movie & 1943 novel The Fountainhead: be your own independent architect, do what you love to do, put it out there, see if anyone else loves it too, find your birds of a feather, flock together, and f— everyone else, especially your competitors on similar projects.

Google wants variable-rate Ethernet

optikos optikos writes  |  about a year and a half ago

optikos writes "When it comes to the fill-rate fraction/ratio of digital-domain Ethernet frames in the underlying analog-domain physical medium, a senior network architect at Google wants to have more flexibility regarding the denominator to push a link's typical fill-rate closer to 100%. The current scheme of inter-Ethernet-frame idle capacity as represented by a numerator that is notably smaller than the (currently-standardized fixed-size) denominator in the fill-rate is claimed to be unsuitable when interconnecting data-centers.

The Institute of Electrical and Electronics Engineers Inc. (IEEE) isn't working on a variable-speed Ethernet standard yet, but Google is pushing for one. It was a point of focus for Bikash Koley, Google's principal architect and manager of network architecture, during a panel session on the last day of OFC/NFOEC last week. What he wants is variable-speed Ethernet. So, instead of running a connection at 100 Gbit/s or 400 Gbit/s, which are the two standard choices, he'd like to pick arbitrary speeds. The technology on the optical side is actually ready for what he's asking. Variable-speed transceivers and flexible-grid ROADMs exist. What's missing is on the packet side: a media access control (MAC) layer that's capable of dealing with a variable-bit-rate physical (PHY) layer.
