It's perfect! Unsinkable? Unthinkable!
No Homer will ever be allowed, and all the regulators will be objective and unbowed!

Plus its SO much easier to deal with disasters at sea and we have such a good track record in doing so.

Astronomers Solve Puzzle of the Mountains That Fell From Space

icebike Re:Doesn't Gravity Affect Angle of Repose? (51 comments)

Yes, but his experimental platform is far from perfect, wouldn't you agree?

He's talking parabolic flights in powered aircraft, which lasts, what, maybe 30 seconds, and could not easily be shielded from all sorts of vibrations.

So the good geologist's work probably can't account for a moon-sized platform, or a mixed particle size, or the inclusion of water ice, etc. The angles do vary with gravity, grain size, grain polishing, binding agent inclusion, etc.

Still the Subject study uses a wide definition of the Angle of Repose ("anything between about 25 to 40 depending on size and type of particles involved."), and they suggest that all (or most) of these observed ridge shapes fit within that definition. While they mention water ice in their theory they don't seem to acknowledge its ability to drastically increase the Angle of Repose, easily up to 60 degrees in terrestrial gravity).

Astronomers Solve Puzzle of the Mountains That Fell From Space

icebike Re:How about... (51 comments)

Exactly, this article essentially is an elaboration on the Wiki Article's theory # 3.

They make much of the angle of repose, but the angle of repose is not a constant. Gravity of the planet/moon affects this angle, (which I am sure they accounted for), but so does the water content, or any other potentially binding agent (frozen CO2, etc) of the material. Even the shape of the grains of sand can affect the Angle of Repose.

Ask Slashdot: What Good Print Media Is Left?

icebike Re:The Economist (282 comments)

Dono If I believe that.

The Economist has always had a penchant for saying very little with the largest number of words.

If you sit down and try to outline one of their major articles, as I recently did, you will see how few points they actually try to make and the inordinate burden they imposed on the reader while making them. And its not like they provide quality supporting documentation to justify their points. Often they simply trout out half truths and over simplifications in point after point of seemingly endless paragraphs of supporting verbiage which provide little enlightenment.

Heartbleed Disclosure Timeline Revealed

icebike Re:"Independent" discovery? (62 comments)

Not necessarily. It may be that the bug was known to others and that Google and Codenomicon were both monitoring channels used by more nefarious types. Both organizations may have independently 'discovered' the bug after each becoming aware that an exploit existed without having full details of the exploit.

And the story should have been about WHEN those nefarious types first started mentioning it, not about when the white-hats actually found it.
Did those blackhats find it by reading the code, or accidentally stumbling upon it in some way?

I suspect it was the former, but I think that discussion is more important than when Google detected it. After all, the implication is that
google discovered nothing, but simply heard about it in the hallway or something.

Private Keys Stolen Within Hours From Heartbleed OpenSSL Site

icebike Re:The CA should not revoke the certificates, (151 comments)

However, the CA should issue the new cert for free in this case. It costs a CA exactly nothing to issue a new cert. Its not a consumable commodity. Allowing them to indiscriminately cancel certs without proof of compromise gives them access to every site's checkbook.

With no PROOF of being hacked, even the the fact that at some point in time the site was running a vulnerable openssl version seems insufficient proof to cancel a certificate, and require payment for a new one. Remember, none of this can be the fault of the site. As long as it is patched now.

And before the CA cancels any certificate, they themselves better be assured that they were always running a clean stack.

Linux Developers Consider On-Screen QR Codes For Kernel Panics

icebike Re:Good idea (175 comments)

how soon until someone accidentally posts a QR code containing confidential information, since they cannot read it themselves.

Since the crash handler itself generates the code that takes your phone's browser directly to the report site, this isn't going to be a problem.

Have you never actually uses a qr code the leads to a web site?

Linux Developers Consider On-Screen QR Codes For Kernel Panics

icebike Re:Dump kernel to serial printer (175 comments)

Or just display a short number code. Displaying a QR code won't solve anything, it will just obfuscate the error and leave the user without any easily memorable reference. This sounds more to me like "let's do it because it's modern and hip" rather than it being actually useful.

The QR code can not only indicate the exact location of the error, but can take you to a website on the phone, with a url long enough to log
  many key points about the error.

Even if it logs very little, developers will get more input this way than they do now, because when your machine is crashed, you can't report anything and once it reboots, you have other priorities than digging in the last crash dump.

However, other than collecting statistics, it might not do any good. Even when you do submit a dump, you get the request to install debug symbol packages and trigger the crash again. Ah, no, that isn't going to happen. Or there will be necessary drivers installed that taint the kernel, and devs wont touch it until replace your video card, untaint your kernel, and trigger another dump.

Study: Exposure To Morning Sunlight Helps Managing Weight

icebike Re:Vitamin D (137 comments)

You've totally missed the fact that the link lead to two different studies one of which was a Meta Analysis of 180 studies, which indicated that there was no measurable effect of Vitamin D. Its not like ONE study was done and it is easily overturned by your google search.

The meta analysis more than likely included all your google search results by proxy. The study is not paywalled so go read it yourself.

This is the beauty of meta-analysis, it can find significant overlooked results of smaller studies and overcomes a lot of researcher bias.

Study: Exposure To Morning Sunlight Helps Managing Weight

icebike Re:Vitamin D (137 comments)

There is no effect of Vitamin D, via supplement or via Direct Sunlight.
Vitamin D3 seems to decrease mortality (of all causes) by 11%.

But I agree that this present study seems to be confusing cause and effect. If you are outside early and running around in the sunshine chances are its not the light of morning that has the effect, its merely the fact that you are more active.

How Satellite Company Inmarsat Tracked Down MH370

icebike Re:They haven't tracked it down (491 comments)

They have tracked it to a place from which It didn't have enough fuel to return.
Unless you are hanging your hat on aliens beaming them up, or a long undiscovered island in the south indian ocean which just happened to have a 5000 foot runway, some times you have to go by the numbers and state that they crashed.

How Satellite Company Inmarsat Tracked Down MH370

icebike Re:This story is so strange (491 comments)

There is very little reason to have spy satellites in the south Indian ocean.
Inmarsat is one of the few companies needing coverage down there because they have the contract for ACARS data an occasional sat phone calls. This area is not even on normal shipping routes.

How Satellite Company Inmarsat Tracked Down MH370

icebike Re:ACARS (491 comments)

No it isn't, its not using data from a system that WAS TURNED OFF within MINUTES of the last radio contact.

How the fuck did this get marked as insightful? Its make a wrong statement that everyone has know has been wrong since the second day.

You should try to keep up with the actual events instead of lashing out on Slashdot.

The DATA transmissions ceased on the ACARS, but the radio system still pings the satellite.
The radio system keeps its link with the satellite as long as the actual transmitter has power.

Just because you stop tweeting on your phone doesn't mean the phone stops talking to towers.

How Satellite Company Inmarsat Tracked Down MH370

icebike Re:Some questions (491 comments)

How come the frequency information of the signal received by the satellite was saved? What is the purpose of saving all that data in normal operations?

And why did it take three weeks to do that analysis?

I thought the same thing.

With digital tuners, what radio system even captures exact frequency these days? Its either in-band our out of band and not heard.

Perhaps these satellite radios are wider band, and therefore they record the exact frequency any transmission arrived, but it just seems unusual to have this information at all, let alone to be able to dig it up out of several days old data.

Your Car Will Soon Sense If You're Tired Or Not Paying Attention

icebike Re:Car Sensors Suck (178 comments)

Everything you said is false.
I mean, I can't imagine how you could be wrong on every single point, unless you are still driving that 82 Toyota.

The headlights recognize tail lights and won't go to bright when I'm following, the car can distinguish someone cutting me off, and brakes just enough to allow for the DIFFERENCE in speed, the blind spot monitoring works perfectly, (and I still turn my head because not all the cars I drive have this). Cross traffic detection is for when you are backing out of parking spaces, not driving.

Basically, I don't think you should be driving period. Your attitude betrays an ego larger than your brain. You don't belong on the road.
Its time to trade in that deadly heap you drive, because your abilities stopped improving years ago.
Humans are the least reliable element in the modern car.

E-book Agency Model struck down

icebike icebike writes  |  about a year and a half ago

icebike (68054) writes "Federal Judge rules against the Agency Model devised by publishers to fix the price of e-Books (as well as paper books) by preventing retailers from setting their own prices, offering loss-leaders, or sales. Still not agreeing to the settlement is Apple, whose entry into the e-book business gave the publishers their foot in the door to impose the Agency Model. (Some suggest Apple may be in bigger trouble than the publishers). Refunds are likely to be imposed for book buyers. Link above contains entire ruling."

The Twitter Patent IPA - Will it work

icebike icebike writes  |  about 2 years ago

icebike (68054) writes "The Register has a story covering the Twitter Proposal for an Innovators's Patent Agreement (IPA) to put an end to endless patent wars. The agreement is meant to be signed by inventors working for corporations, when they assign the invention over to the corporation. The Agreement becomes from that point on similar to a covenant in a real estate purchase, binding on all parties, successors and heirs. The Full Text of the proposed IPA can be found on Github.

The operative portion of the IPA stipulates that "Company, on behalf of itself and its successors, transferees, and assignees (collectively “Assignee”), agrees not to assert any claims of any Patents which may be granted on any of the above applications unless asserted for a Defensive Purpose." It then proceeds to define "defensive purposes".

  It would seem that it would pretty much end any chances of monetizing the patents due to the promise not to use them as a first strike weapon in court, thereby allowing anyone to use the patent without fear of lawsuit.

Will this actually work, and would any companies actually adopt this method of Patent Assignment?"

The ship, The Patino has markings characteristic of naval ships and twin helicopter hangers on the rear deck. The weapons systems include two Oerlikon 20mm guns and two Izar FABA Systems Meroka 20mm close-in weapon systems (CIWS).

presidential Limo trapped on ramp

icebike icebike writes  |  more than 2 years ago

icebike (68054) writes "The BBC has footage of the Presidential Limo being trapped on a steep ramp while exiting a gate at the US Embassy in Dublin. The odd part of the video, is that it seems to suggest that rather than simply dragging its belly, the car seemed to trigger some sort of protective action.
Rather than grating to a stop, as anyone who has high-centered a car remembers, the car stops abruptly and completly.
The front wheels collapsed into the wheel wells, to the point where the car with 6 to 8 inches of clearance between the road and car frame suddenly appears to have less than 3, and the back end jumps into the air and stays high. If the vehicle was high centered, the front wheels should be hanging down, as the weight would be born by the rear wheels and the belly of the car. Instead the front wheels remained collapsed into the wheel wells, and the security detail brings a bus in front of the car so as to cut off the camera view, and provide some protection.

The car appears later in the video seemingly moving under its own power."

Noctilucent clouds likely caused by Shuttle Launch

icebike icebike writes  |  more than 4 years ago

icebike writes "We recently covered the hysteria of Noctilucent clouds here, where there was some suggestions that these were the product of Global Warming due to moisture being lofted high into the atmosphere due to warming.

It now may be that these are simply the product of Shuttle launches.

Science News is reporting in a story about the Tunguska blast that:

"Each launch of a space shuttle, which burns a combination of liquid hydrogen and liquid oxygen as fuel, pumps about 300 metric tons of water vapor into the atmosphere at altitudes between 100 and 115 kilometers. Soon after the January 16, 2003, launch of the shuttle Columbia, a liftoff that took place just after the height of summer in the Southern Hemisphere, noctilucent clouds appeared over Antarctica. Similarly, a widespread display of the night-shining clouds showed up over Alaska two days after the shuttle Endeavour blasted off on August 8, 2007. Previous studies show that in both instances those clouds included material from the shuttle plumes." So Man made after all?"

Does Windows Vista Firewall contain a Tarpit?

icebike icebike writes  |  more than 6 years ago

icebike writes "While testing some TCP network software recently I noticed that an attempt to connect to the software on a Vista machine will take forever (greater than 45 seconds) to time out when the software is NOT actually running AND a firewall exception is in place, or when a firewall exception was specifically not allowed.

However, tearing down windows firewall will let the connection fail quickly (less than 5 seconds) when the target software is NOT running.

All other windows platforms (XP,2K, 9x) appear to fail the connection quickly when the software is not running AND a firewall exception is configured.

I can find no mention of this behavior in Microsoft's site or in any KB article.

This amounts to a defacto Tarpit which seems undocumented.

The software in question is designed to listen on a specific port for a TCP/IP connection, and display information sent from the other end (chat program). I tried several other similar software products with the same result."

This means that if the stock price can not be held above 1 dollar for 10 consecutive days out of the next 180, SCO will be delisted. It would then join the Pink Sheets, where penny stocks are traded, (and usually hyped by untold volumes of spam promising a big campaign).

Aways a secure product (on a scale of one to Outlook) Pegasus had a faithful following world wide, but a small share, and insufficient funding for it to continue.

From the announcement page at http://pmail.com/ David announces
  "It has been a privilege to be of service to the Internet Community for such a long period of time — I am only sorry that I am not able to continue doing so."

Always a class act, Harris gave away Pegasus. If you wanted to help fund the development you could buy manuals. His product did not contain any annoying advertising, and handled Pop and Imap elegantly with a simple clear interface."
