Study Shows How Humans Can Echolocate

Midnight_Falcon The bike riding is less than impressive.. (136 comments)

If you'e seen videos of him doing the supposed "riding bike down the street," he only gets a handful of meters, slowly, and it is a very painstaking bike ride. They even edit his video to show the more successful parts. I looked into this after seeing his TED talk -- while echolocation seemed pretty neat, it definitely seems like his foundation is exaggerating its efficacy. It definitely does something, his bike riding is awkward at best but I think it's talked up in an effort to encourage others to learn it as well.

American Express Seeks To Swap Card Numbers For Secure Tokens

Midnight_Falcon Re:Finally.. (130 comments)

I'm pretty sure I'm not the "asshole" here...in that, well, you chime in on a conversation just to call someone an expletive, or insult them..without even bothering to google OTP first. Notice in all my posts in my post history I don't resort to name calling like you have done here -- it's a clear sign logic has failed, and all you have is nonsense rhetoric and insult to offer.

American Express Seeks To Swap Card Numbers For Secure Tokens

Midnight_Falcon Re:Finally.. (130 comments)

Clearly I should've spelt out OTP to avoid confusion in this context..except, yes, I do PCI compliance audits for a living, and this acronym seems very second-nature at this point. However though, I wasn't the one confusing OTP..it was the readers applying their own cognitive bias to apply the "one time pad" meaning here, even though the context clearly pointed away from that.

Sure they do. It's actually common in security parlance. When was the last time you made it to a security convention?

Here's an example in commercial marketing:

American Express Seeks To Swap Card Numbers For Secure Tokens

Midnight_Falcon Re:Finally.. (130 comments)

What am I saying? I think I have some idea.

I've done plenty of PCI compliance audits, CISA certified, yadda yadda.. so you would hope I have some insight here.

What do you know about crpytography? For example, if AMEX cards had a smart card in them that also had a OTP functionality -- like YubiKey, meaning a public key, an OTP (one time password, not pad), and a counter -- they could be made much more secure.

How so, you ask?

  • Merchant validation service would validate based on OTP, this could be API-based with only AMEX etc storing shared secrets with the OTP devices
  • Replay attacks prevented by counter -- so old OTPs could not work if re-used
  • May require information on magnetic strip + RFID/NFC/OTP device, thus ensuring the card is present
  • POS systems could be compromised and since the OTP/counter changes, compromise of PAN data stored at endpoints would be far less valuable

This is just the tip of the iceberg in terms of the many advantages such a system would have on making fraud a lot more difficult, and thus less profitable/worthwhile.

If you're going to troll at least you give the benefit of the doubt on acronyms. OTP = One Time Password ...NOT one time pad.

American Express Seeks To Swap Card Numbers For Secure Tokens

Midnight_Falcon Finally.. (130 comments)

With OTP and related two-factor authentication technology becoming so widely available, one would have hoped that credit cards would implement some type of solution either using OTPs instead of cards, or augmenting them with OTPs. Millions of dollars in fraud prevention, "credit monitoring" and other such services would be saved by simply using solid cryptographic systems for the payment networks.

PCI compliance would probably be a lot less of a headache as well...

Tim Cook: "I'm Proud To Be Gay"

Midnight_Falcon Re:News for Nerds? (764 comments)

The problem is the context these terms are used in. Perhaps it is a result of living with so many attacks, but the various transgendered people I meet seem to have one thing in common: being very defensive. They throw around the word "cisgendered" almost like a racist epithet, .e.g. "Who cares what that stupid cismale thinks." -- which, because they're a minority group, seems to be tolerated. But it is not much better than saying something most people would agree as offensive, like, "Who cares what what stupid Jew thinks?"

I have been in many situations where it seemed like the transgendered person was trying to trap people into saying something they consider offensive, using the wrong pronoun or what not, just so they can act out. This has made many, including me, grow tired of the constantly changing politically correct vocabulary associated with these people -- as well as the over-the-top dramatic defensive attitudes.

Tech Firm Fined For Paying Imported Workers $1.21 Per Hour

Midnight_Falcon fwd.us! (286 comments)

The real reason tech companies want more H1B Visas is clear: So they can exploit foreign workers in a mix between the days of indentured servitude and the company towns of the Industrial Revolution. Too much education and culture has gone into making Americans averse to such exploitation; but companies manage to sponsor employees and get away with paying them a pittance under this system. It's the closest thing to chattel slavery still legally viable.

Then, when it gets found out, the company pays a slap-on-the-wrist order a fine....almost nothing compared to fines for sexual harassment or other torts that might affect Americans.

An Algorithm to End the Lines for Ice at Burning Man

Midnight_Falcon False "Solution" Ignores the real problem (342 comments)

Bennett went to Burning Man once in 2013 and now thinks he's somehow relevant to Burning Man and writes about it online more than many core community members who actually get stuff done. His one experience with Burning Man was as little more than an ancillary helper at a smallish camp. His bold "solution" to this problem actually ignores the key issue that workers are not moving fast because there is no motivation to sell more ice.

The reason the ice line moves so slowly is everyone is a VOLUNTEER and they are not paid to sell ice. They just get a free ticket working for Arctica. They're also stoned, and burnt out, and aren't really concerned about moving fast in the high heat of the day to get people more ice. If they just get through their shift, they're happy -- people waiting is not a concern.

The solution Bennett should be looking for should not be some magic "algorithm," but a political one involving staff being paid more and being hired for merit, rather than knowing someone in Arctica. His attachment to this idea and even stating that there are no counter-arguments shows his inexperience and cursory knowledge about Burning Man in general. Technically, his idea might work, socially, it'll never happen.

As far as I know, Bennett's social connections to Burning Man are very limited, so this would be something that flies above his head. Burning Man is predominately, a social event, and technical/algorithm solutions ignore the fact that the reason most core contributors are there is for social reasons.

Sci-Fi Authors and Scientists Predict an Optimistic Future

Midnight_Falcon Re:Jean-Luc Picard is my idol... (191 comments)

Yes, there's tons of holes in it -- e.g. everyone speaks English via the dubious "Universal Translator," money seems to sort of exist with latinum and somehow Starfleet officers seem to have it..etc etc...but there are also tons of holes in other SciFi.

William Shatner actually ended up making TEK to essentially describe a dystopian future of people addicted to quasi-holodecks :) But it was awful! It, also, had tons of holes in it..despite being more, dystopian.

In the end it's not about the holes in the optimistic or pessimistic portrait the show paints. It's about whether the portrait the show paints gives you something to aspire towards or, by contrast, makes you skeptical or fearful of scientific change. In the latter case, this would make you more comfortable in the way things are, the status quo of our time, as not being so bad. In the former, it would make you less comfortable and want to push things in a positive direction so life could be more like this vision of the future.

Sci-Fi Authors and Scientists Predict an Optimistic Future

Midnight_Falcon Jean-Luc Picard is my idol... (191 comments)

and I think watching Star Trek: The Next Generation as a child inspired me to become an engineer.

Star Trek painted a very optimistic picture of humanity, of a few generations from now mankind not being focused on money, but instead ideas, and progress/wellbeing for all of humanity. About technology (foremost the replicators) really making the world a better place.

Contrast this to the reboot of Battlestar Galactica , which paints a very dreary portrait of advancement of science/artificial intelligence causing the downfall of humanity..

The Computer Security Threat From Ultrasonic Networks

Midnight_Falcon Re:Hardware sampling rates (121 comments)

Of course I use profanity. Audiophiles are fucking morons. They're dumber than people who wage political campaigns against vaccines. People who are afraid of vaccines at least have minor blips of correlation to base their fears off of, while the science simply shows no connection. Audiophiles have hard science and experimental data that actually proves they're wrong.

Sometimes, there is scientific data about audiophiles being wrong (like FLAC vs 320k MP3), but no..any idiot can tell the difference between a Cerwin-Vega PA and a Funktion One. Klippel tests can provide scientific data to analyze why this is the case. So, your argument is far too broad to be true. Also, inserting profanity rather than logic or anything to backup your claims shows you're making emotional arguments rather than scientific ones.

I'm not talking about frequency response, I'm talking about sample rate because the person I was replying to was talking about sample rate in relation to FLAC, MP3, etc., and the discussion thread is about limiting the sample rate of the sound card. Please read before you post.

FLAC vs MP3 is largely a result of the cutoff at 16khz of MP3 sound, and attentuation of treble frequencies. While someone might have talked about sampling rate (which does matter), the vast majority of the perceived difference in quality is due to the attentuion of treble frequencies. Thus, my comment was completely germane to the subject matter.

You're wrong about music production as well. People play instruments and they're recorded. There's a lot of digital manipulation, and lots of canned or digitally-generated samples are used, with some bands/artists using more than others, but the vast majority is still sourced from people playing instruments and singing into microphones. Regardless, none of this has anything to do with music - it simply has to do with sound and the reproduction thereof. You CANNOT hear any frequencies higher than 20 kHz. If there is a 99 kHz tone in the room interfering with things, you hear the interference pattern's effects in the human-audible range. You do not heat the 99 kHz tone. Everything you hear is within the human-audible range, and double that is enough to transparently reproduce any sound a human could ever hear.

I am not wrong about music production. Perhaps in the 90s when you acquired this knowledge it was true, but now this is not the case. Yes, people sing into microphones. That's where it ends. Hip hop music, pop music, electronica all use totally digital sources these days for the basslines, synth lines, and pretty much all the music besides vocals. Vocals themselves are manipulated to hell and back with vocoders, chorus, flanger etc. The second part of your statement is somewhat true but misleading. Yes, you do not hear the 99KHZ tone. However, if you have a 16khz audio signal with a 22khz overtone, many would describe the sound as being "warm" due to the interference of the higher-frequency overtone with the lower frequency signal.

Now this is just complete bullshit. If you can hear the speaker it is producing a pressure wave. If one speaker is a box and one speaker is a human they're still both producing pressure waves. When two pressure wavefronts collide, such as at your ear when you're hearing them, they interfere. A speaker's quality is measured by its ability to reproduce the input signal. For all speakers humans listen to, the highest frequency that matters in 20 kHz. You cannot hear anything higher than that. You are not special. Any audible interference from higher frequency sources is already baked into the signal, and a doubled sampling rate covers any aliasing. A speaker's quality has nothing to do with your ability to engage in conversation in front of the speaker. If I output the inverse of what you're saying people wouldn't be able to hear you, by design. If I output exactly what you were saying people would be able to hear you more loudly. If I output X people's ability to hear you depends entirely on the interference between X and what you're saying and their own brain being able to concentrate and fill in gaps. The speaker's quality has to do with how well X matches the input. There is no connection between your conversation and the speaker's quality.

You are a madman. Never did I claim to hear abovd 20KHZ or anything outrageous. There is a great deal of connection between the speaker (and amplifier and processor's) quality and your ability to hear a conversation at normal volume in front of it. Because of the speaker quality matching the input so well, it does not distort into other frequencies. Thus, it is easier for a human ear to pick out normal conversation and removes the need to shout. I have countless times had to shout over subwoofers/etc to talk to people at a club or party, but also, countless times when good quality soundsystems are used (like Danley, Funktion-One) with quality processing and components, I am able to have a conversation a couple meters in front of the soundsystem at normal volume 100% intelliglbly.

The Computer Security Threat From Ultrasonic Networks

Midnight_Falcon Re:Hardware sampling rates (121 comments)

You use profanity to refer to audiophiles and you clearly have no idea what you're talking about. 96 or 192kHZ sampling rate doesn't have much to do with frequency response , which is what we are takling about.

Most music these days is not produced via an analog signal to a microphone. Rather, a digital process creates an analog waveform in software like Ableton Live, Cubase, etc. If an overtone or other sonic artifacts are applied, you can definitely hear the effects on the music even though these are at high frequencies..

Speakers are graded for quality using the "Klippel" test, which measures amount of distortion and how clean the signal comes out at various frequencies. With good speakers, you should be able to have a conversation right in front of them at loud volume, and not have to speak loudly or bring up your voice to clearly understand the person. That is because the audio waveform will be clean and not distort other frequencies.

The Computer Security Threat From Ultrasonic Networks

Midnight_Falcon Re:Hardware sampling rates (121 comments)

Hardware sampling rate is actually a kind of roundabout way to do it. More easily, one can place an analog high-pass filter set at 20KHZ or so before the speakers in the sound driver hardware etc. These are very cheap for low-power applications like laptops.

The Computer Security Threat From Ultrasonic Networks

Midnight_Falcon Re:Hardware sampling rates (121 comments)

While this is true, in that "warmth" is perceived by human ears somewhere in the 16KHZ-25KHZ range, over 30KHZ won't even create a "warm" sensation to human ears. In the range of this network, which from TFA appears to be 20khz, many humans will be able to hear something.

If music is properly recorded and mastered, it will typically not contain any artifacts above the 25-30KHZ range. If you are playing music on a high-end system above this range, typically one will apply a high pass filter on their digital processor or amplifier in order to filter out ultrasonic frequencies, which may damage tweeters trying to reproduce sound beyond their response range.

Disclaimer: I am an audiophile. I use SEAS.no speaker drivers, custom enclosures, and high-end amps like QSC and ZED Audio.

U.S. Cedes Control of DNS to ICANN

Midnight_Falcon (2432802) writes "Sixteen years after Jon Postel's famed attempt to bring the DNS system under IANA control, the U.S has agreed to cede control of the root DNS servers of the internet to ICANN.
