Email Is Not Going Anywhere

l2718 "The web we lost" (235 comments)

The author is quite confused: email predates the web by decades. It predates the internet.

l2718 "Good math doesn't know gender" (75 comments)

Yes, the math doesn't know gender, but the mathematicians who evaluate each other (say for promotion or for prizes) do know. Yes, the situation today is very different from the past, but biases do exist. For a strongly worded view point on this try Izabella Laba.

SpaceX Chooses Texas Site For Private Spaceport

l2718 Why the "incentives"? (113 comments)

These $20M are good for SpaceX, but why are they good to the taxpayers of Texas? This feels like the "incentives" provided to sports teams where somehow the projected benefits to other local businesses never materialize.

Comcast Carrying 1Tbit/s of IPv6 Internet Traffic

l2718 Re:IPv6 How will it happen? (146 comments)

Why should users care? How many "users" are aware of IP addresses, or view them as anything but a string of meaningless digits? The "complexity" of IPv6 falls entirely on sysadmins and on those who implement IPv6 stacks, that is on experts. It's possible some users will have a home network on the 192.168.x.x IPv4 range connected via a NAT to the IPv6 internet, but this choice will be made for them by the people who write NAT software: home users universally use first-come-first-served DHCP to assign addresses on their home network so they never see even the local IP addresses. I like to remotely SSH to my home computer, so I note the IP address assigned to my NAT by the ISP, but a typical user can't pull that off. I also like to have fixed IP addresses inside the home network so I can reliably use SSH between the machines. You might be diong the same. But the average user can't and doesn't feel the need to.

Firefox 33 Integrates Cisco's OpenH264

l2718 bad for standards (194 comments)

Mozilla capitulating on the tag has serious implications for web standards. By including patent-encumbered code in the browser they take the rug from under those in the www foundation that argue for free web standards. Yes, some websites wanted to use H.264 for video encoding, but Mozilla shouldn't have abetted them.

White House Punts On Petition To Allow Tesla Direct Sales

l2718 Alcohol is a consumer good too (382 comments)

Post-prohibition most states regimented the alcholic beverage distribution chain into a three-tier system: producers, distributors, and retailers. As you can see this is even worse than with cars. For example, vinyards often cannot sell directly to the public, and they can't sell directly to pubs or wine stores. The middlemen must be paid ...

BMW, Mazda Keen To Meet With Tesla About Charging Technology

l2718 Standardization is critical (137 comments)

For wide adoption there needs to be a full market around electric vehicles: opportunities to build charging stations, sell home charging equipment and so on. Gas stations are possible since practically all cars use the same fuel, but also because they have very similar intake openings so that the pump can stop by itself.

Tesla by itself is too small to set standards, so this is good news. It also shows how disclaim in patents helps: the benefit from a greater and more active market exceeds the payoffs from discouraging competition.

Which desktop environment do you like the best?

l2718 FVWM (611 comments)

A few years ago I switched from tvtwm to fvwm and I'm very happy. One year being forced to endure unchangeable defaults chosen by Apple engineers (which are no doubt very good for most of their customers) further cemented my preference. I still don't understand why focus policy or keyboard bindings are the business of the window manager designer.

NYC Councilman (and Open Source Developer) Submits Bill Establishing Open Source Preference

l2718 Consider incidentals (105 comments)

Taxpayers should not be paying for someone's pet cause ... Proper action would be to mandate the government to use the best software for the task at hand ... Let the technical merits decide.

I'm sorry, but while technical merits should be paramount, they are not the only consideration. Public contracting is not an exact science, and it is entirely appropriate to have non-technical considerations tip the scales in close cases. So while Free Software should not be mandatory, legislating a preference for it makes perfect sense.

Furthermore, there are considerations beyond the needs of a specific project and tender. Free Software has an externality: when the government (as a customer) requests modifications and improvements (and pays for them to be created), everyone benefits. For example, when my university has Blackboard Inc fix a bug (or improve the software) only Blackboard captures the value (when they sell their software to the next customre). If we were using Moodle, every other Moodle user would automatically benefit. Had we opted for Moodle, we'd also benefit from fixes made by other universities.

Discrete Logarithm Problem Partly Solved -- Time To Drop Some Crypto Methods?

l2718 Re:Not much to see here. (114 comments)

Yes, these elliptic curves address defined over a finite field, but there's no known connection between the discrete log problem for the field and for the elliptic curve.

Discrete Logarithm Problem Partly Solved -- Time To Drop Some Crypto Methods?

l2718 Re:It's still NP. (114 comments)

Squaring key lengths would be entirely impractical. That said, the improvements only apply to a case of discrete log which isn't actually in use. Cryptographic algorithms generally depend on hardness of discrete log mod p (p a large prime), not in the field with p^k (p fixed, k large).

Discrete Logarithm Problem Partly Solved -- Time To Drop Some Crypto Methods?

l2718 Re:arXiv link (to the technical paper) (114 comments)

Yes; the preprint was posted to arXiv when the research was completed. Obviously Science Magazine (the source for the slashdot posting) prefers to write about results when the journal article comes out later, because otherwise the magazine would to check the preprints for correctness on its own, which it can't be expected to do.

Discrete Logarithm Problem Partly Solved -- Time To Drop Some Crypto Methods?

l2718 Somewhat (114 comments)

Reading the paper, the most notable feature is that their algorithm is efficiency for constant characteristic, including the common case of fields of characteristic 2. It's also okay for the characteristic to grow somewhat with the size of the field, but not very fast.

This is not at all relevant to most implementations of DH, which use prime fields of large characteristic. For example, DSA depends on discrete log modulu a large prime p. In particular, I wouldn't worry about forward secrecy of current internet traffic.

As Species Decline, So Do the Scientists Who Name Them

l2718 So what? (76 comments)

If DNA sequencing means taxonomy is now straightforward, then it's good students are switching to other fields. The goal of science is to solve problems, not to ossify. In this case, while taxonomy may cease to be a significant research field, morphology (understanding the structure and evolution of plants and animals) is surely going to continue. The people doing it will simply not be called "taxonomists" anymore.

During the 80s and 90s there were different projects trying to determine the cosmological parameters (mass density, curvature, cosmological constant, Hubble constant, etc). Then WMAP was launched in 2001, and by 2006 (release of 3-year data) the previous techniques were obsolete. Do you think many students in 2001 started working on the old techniques? Should they have? But we haven't lost interest in the cosmological parameters.

$200 For a Bound Textbook That You Can't Keep?

l2718 Re:A consideration for professors (252 comments)

Many publishers will try to bribe professors to use their book for a course. Either you're very honest & kind or your class is small.

Do you have first-hand experience with this? It has never happened to me. Publishers routinely send me free books with the hope I'll use them for a course. Almost all have a policy of giving you a free copy of any book you make mandatory for a large enough class (say 100 students) -- which is the closest it gets to a "bribe" -- but in fact it's basically irrelevant to the decision. First of all, the only reason I need the book is for teaching purposes, I'm not particularily motivated to own it except for use during that particular class. Second, since the book is for teaching, if I don't have a copy the academic department (my employer) will buy one for me to use during the course. So the only thing this "desk copy" policy do is save some money for my boss; it has no effect on how I choose a textbook.

$200 For a Bound Textbook That You Can't Keep?

l2718 Re:This has little to do with copyright law (252 comments)

I'm a professor, actually. In two words, you're wrong . If the book is only used in the class of the professor who taught it, the book will go out of print in a jiffy, and in any case the total harm to a single class of students is negligible. For a book to actually stay in print, many professors in many universities must use it. In this case very few will, and the problem will solve itself.

Diebold vote-tabulation software loses votes

Probably posting the source code on-line before the elections would be a nice complement, as well as verifying that the software you run is the software that gets posted."

Voting machine discrepancies in NJ primaries

l2718 l2718 writes  |  more than 6 years ago

l2718 (514756) writes "Prof. Ed Felten has posted a voting machine summary printout from the recent New Jersey primaries, clearly documenting a bug in the Sequoia "AVC Advantage" machines used. Specifically, the machine claims 362 Democratic ballots and 60 Republican ballots have been accessed, while at the same time recording a total of 361 votes for Democratic party candidates and 61 for Republican party candidates. The results literally do not add up. Sequoia's concern that the State might arrange for independent investigation of this bug is what prompted the nastigram we discussed yesterday."

Warner Music CEO: war with consumers was wrong

l2718 (514756) writes "Edgar Bronfman, CEO of the Warner Music Group, publicly framed the music industry's failure to accomodate file-sharing as an "invadvertent" war on consumers. I'm left wondering how you can file a series of lawsuits inadvertently.

"We expected our business would remain blissfully unaffected even as the world of interactivity, constant connection and file sharing was exploding ... By ... moving at a glacial pace, we inadvertently went to war with consumers by denying them what they wanted and could otherwise find and as a result of course, consumers won."

Vodka used as medicinal alcohol

l2718 l2718 writes  |  more than 6 years ago

l2718 (514756) writes "A large dose of ethanol is commonoly used to treat poisoning by other alcohols. When Australian doctors ran out of pure alcohol while treating an Italian tourist who drank ethylene glycol, they tried an alternate medical protocol instead.

"The patient was drip-fed about three standard drinks an hour for three days in the intensive care unit," [a doctor] said. "The hospital's administrators were also very understanding when we explained our reasons for buying a case of vodka."

Reports: Voting machines fail review

l2718 l2718 writes  |  about 7 years ago

l2718 (514756) writes "The California Secretary of State has released the reports of the teams studying e-voting machines from Dieblod, Hart InterCivic and Sequoia. These were three source code study teams (one for each manufacturer), a "red team" tasked with developing exploits, and an accessibility review team. The conclusion: in all cases the design and implementation are extremely insecure and vulnerable. See also the reactions by Ed Felten and Avi Rubin."

l2718 (514756) writes "Novell has made their next move in their lawsuit against SCO. Clause 4.16(b) of the contact of sale for UNIX System V between Novell and the Santa Cruz Operation (SCO's predecessor), says, in part:
at [Novell]'s sole discretion and direction, Buyer shall amend, supplement, modify or waive any rights under, or shall assign any rights to, any SVRX License to the extent so directed in any manner or respect by Seller.
Background: After SCO claimed to terminate IBM's UNIX license, Novell directed them (on June 9th, 2003) to waive their right to do so. If granted this motion will make another part of SCO vs. IBM go away — IBM's attempt to enforce the clause in their amdended license agreement saying the license grant is irrevocable and perpetual. Fortunately the same district judge and magistrate judge are overseeing both cases."

Controlled by a standard PC board and running a Linux-Apache-MySQL-PHP combo the machine makes any of 96 flavours of ice-cream as requested by the customer, and can be remotely monitored and controlled. This should be an interesting AMD-Redhat flavour to try."
