Electric Eel Shocks Like a Taser

bradgoodman Already knew that... (29 comments)

They describe this in the signage on the eel tank at the New England Aquarium. They even have a "shock" meter - and they tell you when it is getting ready to shock, you will see some spaced-out low-intensity pulses before "the big one".

Nuclear Weapons Create Their Own Security Codes With Radiation

bradgoodman Random Number Generation (106 comments)

So from what I am guessing - they are referring to using the radioactive decay of the materials for true random number generation. This concept isn't new - the unpredictability of radioactive decay has been a know source of "truly random" numbers. The article infers that it could use this to generate a key that could be shared with an external authentication mechanism - but you could do this with any random number source. You'd think they would have mentioned something like "quantum entanglement between the weapon and the president" (which might have been interesting) - but no.

Ask Slashdot: How To Unblock Email From My Comcast-Hosted Server?

bradgoodman Relay through Comcast (405 comments)

I had this problem too. I simply use Comcast's SMTP servers to relay my messages from my own SMTP server. You are required to configure SSL-secured transport only, and required to use your Comcast credentials when sending message to the relay. In-turn, when Comcast passes the messages, the services [you mentioned] accept them, but they still are shown as coming from my servers.

You don't have to "use Comcast's mail service" - they just want to use Comcast as a way of providing some accountability as to where the email is coming from - as a way of limiting spam.

OpenBSD Drops Support For Loadable Kernel Modules

bradgoodman Re: Devel/Debug (162 comments)

But then you'd need to reboot to load it, I'd assume.

OpenBSD Drops Support For Loadable Kernel Modules

I shutter to think of how this would impact the development/debug cycle of an otherwise simple device driver.

Internet Explorer Implements HTTP/2 Support

bradgoodman Re:1.2 Ghz, and again - binary orthogonal to compr (122 comments)

Compressed is faster on the wire, but takes more CPU time to decompress. If I have a 100GbE network connection coming into a server - my network bandwidth might outpace my compute abilities.

Internet Explorer Implements HTTP/2 Support

bradgoodman Re:decompression: 800 Mbps (122 comments)

That doesn't mean anything. Were you running on a 3GHz Ivy Bridge server, or a little PIC IoT device? How much CPU time did it take? How many did your application need/require? Did the net result of header decompression along with the easier parsing of the binary header take more or fewer CPU resources then the older uncompressed, ASCII header? etc..etc..etc..

Facebook Ready To Get Into Healthcare

bradgoodman Facebook: "The Privacy Kings" (99 comments)

I can't possibly envision ever making Facebook privy to ANY health issues whatsoever. They would gladly shill that information out for profit - undoubtibly why they're doing it. With something such as health issues which are so confidential, making Facebook privy to any of this would be absolutely terrible.

bradgoodman Header Compression + Binary Headers (122 comments)

Seems like the efficiency you gain parsing the binary header would be lost with the need to first decompress it ;-)

Octopus-Inspired Robot Matches Real Octopus For Speed

bradgoodman Not "sustained" speed (71 comments)

Creatures that use this form of population do it only for "bursts" - like to escape a predator. They cannot sustain this speed. If they used this form of propulsion for a submarine, that would be one hell of a jerky ride.

Why You Can't Manufacture Like Apple

bradgoodman Re: Apple REULEZ! (408 comments)

If there is one thing Steve Jobs taught me,is that Apple isn't about "the technology". The view as a "technologist" may not even be germain as you think. He's always been about "usability" - but it's more than just that. Even this article talks about Apple as a battery company, a manufacturing company, a machine tool company, etc. Even the last video saw on the watch made me realize that I was more impressed with it a piece of jewelry than a piece of technology. With Apple,you often have to look at it from a perspective that has nothing to do with "technology" to really understand it.

DARPA Wants To Kill the Password

bradgoodman Biometrics? Over Internet? (383 comments)

I concur with the previous post saying you "can't change" biometric stuff if your password is "compromised" - but my further point is that biometrics are "secure" in an "embedded" world when you have a physical scanner attached to a physical device. When you're on the "open internet" - and such biometric data has to be collected and shuttled accross "the 'net" - you now have the same sort of issue as with "traditional" passwords - i.e. someone snarfing and/or "replying" that data.

So whereas biometrics might replace a traditional "password" - we need more systems which aren't vulnerable to the type of 1.8-billion-password-stealing-Russian-problems we see all over the place. I have been a big fan of much of the two-factor stuff, and some of the hashing schemes out there. It will be interesting to see what kind of other solutions could exist - though I don't think anything "static" like biometrics gets us anywhere.

Ask Slashdot: Open Hardware/Software-Based Security Token?

bradgoodman Google Authenticator (113 comments)

Google Authenticator is an open source, RSA-soft-token-like system for two-factor authentication. Free applications exist for iPhone, Android, etc to act as your "key fob", and free, open-source PAM and Apache plug-in modules exist to allow you to require the tokens for SSH or web login.

I'd include links - but there are a lot of them depending on what you want (Linux, PAM, Apache, Andoird, iOS, etc) - So, "Just Google it!"

Build Your Own Gatling Rubber Band Machine Gun

bradgoodman Doesn't show anything (39 comments)

Very poor fast-forwarded, un-narreted video of how to load it. No video of it actually working. I'm assuming it did - but kind if think if it really worked well - they'd show that - or show how to use it. I kind of wonder how it worked - and it if it actually did at all.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

bradgoodman Re: I know you're trying to be funny, but... (739 comments)

I've been doing Linux development for about 15 years - including lots of kernel work. I never have, nor ever would posted anything to the kernel mailing lists. With a few exceptions - like when I can hand it off to someone else or go through a third-party - is rather have one of my patches die - than to submit it. Reason? I've seen this kind of attitude and "abuse" and - quite frankly - would never want to subject myself to this kind of abuse should anything I say or submit be erroneous and have to tolerate listening to how "retarded" I or my work is. Personal feelings aside - I wouldn't want such very public commentary about me or my work living in such a perminant and searchable archive - say by some future employeer. I wonder if I'm alone. I wonder if others have the same attitude. I wonder if some of the actual smartest people in the world (not me) might have done some great work - but would be too shy to ever let themselves be noticed.

Reports: NSA has cracked much online encryption

bradgoodman bradgoodman writes  |  about a year ago

bradgoodman (964302) writes "CNN is reporting that the NSA in conjunction with the UK equivalent QCHQ has "cracked much online encryption". This seems to have been done by an ongoing attempt to systematically add "backdoors" and other hidden vulnerabilities into a multitude of commercial services, products and web sites. It does not go on to explicitly state there has necessarily been any "new math" in attacking the underlying algorithms themselves, though it does mention the use of "supercomputers" in the cracking."

Massive New Ninth Planet Found?

bradgoodman bradgoodman writes  |  more than 3 years ago

bradgoodman (964302) writes "The Independent reports: "If you grew up thinking there were nine planets and were shocked when Pluto was demoted five years ago, get ready for another surprise. There may be nine after all, and Jupiter may not be the largest.

The hunt is on for a gas giant up to four times the mass of Jupiter thought to be lurking in the outer Oort Cloud, the most remote region of the solar system. The orbit of Tyche (pronounced ty-kee), would be 15,000 times farther from the Sun than the Earth's, and 375 times farther than Pluto's, which is why it hasn't been seen so far.

But scientists now believe the proof of its existence has already been gathered by a Nasa space telescope, Wise, and is just waiting to be analysed. ""

Google demonstrated Wave at the Google I/O developer conference in San Francisco, California, in May. The closed group of beta testers will help Google fish bugs out of the application before a public release by the end of the year, according to the Google Wave Web site."

Hudson Plane Crash - Are you outraged?

bradgoodman bradgoodman writes  |  more than 5 years ago

bradgoodman writes "There is no doubt that the landing and rescue of US Airways flight 1549 on the Hudson River was nothing short of remarkable — but am I alone in my outrage? Everyone on the Titanic would have survived had it gone down in the middle of the Hudson river in the middle of the afternoon. Didn't the Titanic teach us that we needed life rafts for everyone on board? There were none for the vast majority of passengers. Even with the landing as flawless as it was, had this happened even a few miles off shore, hypothermia could have killed dozens of people. One of the rafts inflated even upside down. Is this going to ignite some major changes? I think we got very lucky."

Chicka Chick Boom Boom: Cryptography for Toddlers?

bradgoodman bradgoodman writes  |  more than 6 years ago

bradgoodman writes "Am I just having one of those psychotic episodes where you see similarities and correlations between random things, or... Is the popular Children's alphabet book "Chicka Chicka Boom Boom" really about cryptography?

For those who aren't familiar with it — the first page reads like a textbook case from a cryptography text:

"A told B, and B told C: "I'll meet you at the top of the coconut tree."

The illustrations go on to depict the letters of the alphabet — scrambled, mangled, contorted and rearranged. Is there a conspiracy here, or do I just need to lay-off of the cold medicine?"

Wii Fit: Emperor's New Clothes?

bradgoodman bradgoodman writes  |  more than 6 years ago

bradgoodman writes "I've seen the Central Park release event, and been hearing all the buzz about Wii Fit on the web, in the media, and from other users. I'd frantically gone from store to store every day until I finally got my hands on one. I rushed home and tried it, and, what a let down! I don't want to go into detail on why it is so bad, and how it is nearly impossible to get even a moderate workout from this device. My Wife was all excited for it, tried it once, and that was the end of that. My question to Slashdot is: Why is everyone so up on Wii Fit? Why hasn't everyone realized how poor it is? Where is all the hype coming from? Is this an artifact of Nintendo's artificial short-supply — i.e. if you can't get it, you want it even more? Who can I slap to snap them out of it?"

World of telecom about to change as we know it?

bradgoodman bradgoodman writes  |  more than 7 years ago

bradgoodman writes "We've all heard of Google's coveting of the 700MHz spectrum, and of their desire to keep it "open" with respect to equipment that can be used on it. Then there is of course the "gPhone", and it's OS, etc. Today I heard for the first time (I live under a rock) about their acquisition of a service called "GrandCenteral". GrandCenteral does a lot with integrating land-lines, multiple phones, incoming calls, contact managment, voice-mail, etc. etc. and of course wraps it in with web-based management. I initially thought it was pretty different and interesting, imagining what you could do with it. That's when the light-blulb turned on: Using custom equipment (gPhone) on a spectrum (700MHz) which would integrate it into a completely new type of telecom paradigm (GrandCentral) — is there a coup brewing in the world of telephony as we know it???"

Man flies 193 miles in lawn chair

bradgoodman bradgoodman writes  |  more than 7 years ago

bradgoodman writes "BEND, Oregon (AP) — Last weekend, Kent Couch settled down in his lawn chair with some snacks — and a parachute. Attached to his lawn chair were 105 large helium balloons.

Balloons suspend Kent Couch in a lawn chair as he floats in the skies near Bend, Oregon, on Saturday.

With instruments to measure his altitude and speed, a global positioning system device in his pocket, and about four plastic bags holding five gallons of water each to act as ballast — he could turn a spigot, release water and rise — Couch headed into the Oregon sky."
