Verizon's Accidental Mea Culpa

CanadianRealist Re:Verizon's Response (390 comments)

Woosh? Continuing from the part I quoted:

Maybe they can't afford the small piece of cable between our two ports. If that's the case, we'll provide it.

Does that sound serious to you? I'm sure the part about them being willing to provide the cable is serious. The part about maybe Verizon not being able to afford the cable ... probably not. Verizon are trying to get other people to pay for the service their customers are already paying them to provide. They have to justify that somehow. L3 seems to be pointing out how ridiculous Verizon is being. I was just piling on.

Oh and:

Not very apparent - seems confusing

I'm pretty sure that subtracting "seems confusing" from "Not very apparent" yields 0. ;-)

Verizon's Accidental Mea Culpa

CanadianRealist Verizon's Response (390 comments)

Level3 also offered to pay for the necessary upgrades to Verizon hardware: "... these cards are very cheap, a few thousand dollars for each 10 Gbps card which could support 5,000 streams or more

Verizon's response was "Ok, but these cards tend to wear out pretty quickly so we'll need you to pay that amount each month. 5,000 streams may sound like a lot, but they don't last very long. A person watches a few movies a week, maybe a couple of youtube videos per day, that's like 20 streams in one week, and that's only one customer. Before you know it, you've used up all 5,000 of those streams and the card needs to be replaced."

"Oh yeah, and if it's coming from Netflix then we're using twice as many streams. We use one stream from Netflix to us, then another stream from us to our customers. Maybe you should really pay us that amount every week."

Study Finds Porn Exposure Associated With Smaller Brain Region

CanadianRealist Re:Striatum (211 comments)

This is interesting. I posted elsewhere the idea that something like a "striatum deficiency" (as you phrase it) may be the cause of my depression and frequent porn watching. I didn't think of ADHD, but a few years ago I was diagnosed as having ADHD.

Study Finds Porn Exposure Associated With Smaller Brain Region

CanadianRealist Re:everyone's a brain scientist now (211 comments)

As someone with a long history of depression and high intelligence I've spent quite a bit of time trying to understand my condition. One thing I've noted frequently is that I tend to derive less enjoyment than other people from most activities. (I think this is a cause of the depression rather than a result of it.) The most notable exception is sexual gratification, whether from sex with a partner or from masturbation. I don't find this surprising as I think that it is such a basic part of the way our brains are wired. Given that I am not in a relationship more often than I am, I frequently watch porn to masturbate.

So in my case, I'd say it seems likely that a deficiency in the part of the brain associated with reward processing causes a greater exposure to porn.

Studies: Wildfires Worse Due To Global Warming

CanadianRealist Re:No, no it's not. (379 comments)

Fourthly, there's good reason to believe that at least some of the ones this week were started by (d-bag) arsonists.

The claim is that climate change is making the fires worse. That's very different than the question of how any one fire started.

Your argument is like pointing to a smoker killed in a car crash and saying "see, cigarettes don't cause cancer."

Maybe someone did start some of the fires. That's happened in the past as well. The real question is, are the fires worse now? From the article: in the 80's an average of 2.9 million acres burned each year, from 2010 to 2013 it was 6.4 million acres per year. That sounds quite a bit worse. Maybe the last few years were just unlucky years, or maybe the fires really are getting worse.

Maybe it's statements like yours from "non-scientists" arguing issues other than the ones raised that are confusing things.

The Design Flaw That Almost Wiped Out an NYC Skyscraper

CanadianRealist Re:Missing the obvious? (183 comments)

But wind produces considerably less force at angles.

True, which is why that is not normally considered. But in this case the lack of support at the corners made the building particularly vulnerable to diagonal forces. That was the point I was trying to make with the Lego example. And if you're designing such an unusual building maybe you should consider more than just the first "first obvious choice" for what could go wrong.

The Design Flaw That Almost Wiped Out an NYC Skyscraper

CanadianRealist Re:Missing the obvious? (183 comments)

No, they didn't.

LeMessurier had accounted for the perpendicular winds, but not the quartering winds.

With only the forces of the perpendicular winds considered and reported, the contractor's decision was ok. While it is true that the bolts were weaker than the welds would have been, they were strong enough to handle the forces the design specified. There's a quote by LeMessurier in the podcast that says this.

The Design Flaw That Almost Wiped Out an NYC Skyscraper

CanadianRealist Missing the obvious? (183 comments)

I know hindsight is 20/20 but not considering the effect of wind hitting the corners of the building seems unbelievable. With no support at the corners it seems obvious* that the easiest way to cause a failure would be to apply force directed towards a corner. TFA does say that wind at the corners is not usually an issue, but when designing something so radically different you have to consider the effects of those differences.

*For anyone who has ever played with Lego: imagine building something that looks like that building and think of the easiest way to push it over. Consider how you control the direction when felling a tree.

Google: Our Robot Cars Are Better Drivers Than You

CanadianRealist Re:Yup, and it doesn't matter. (722 comments)

I also think that autonomous vehicles will be much safer than human-driven vehicles. We can keep making them better based on experience while on the other hand we would keep adding new inexperienced human drivers. I'm sure that we can correct any problems that we may find with early autonomous vehicles. I doubt that we'll ever be able to correct human distraction, emotional reactions, bad judgement and general stupidity.

Do you have any stats on the percentage of accidents caused by physical wear and tear on brakes rotors and axles? Or on the "other thousands of extraneous factors" that you've considered? How do those compare to the percentage caused by any sort of human error?

The following claims human error is the sole cause 57% of the time and a contributing factor 90% of the time, while mechanical fault is the sole cause only 2.4% of the time.

Snowden Says He Took No Secret Files To Russia

CanadianRealist Re:Not shared by him doesn't mean a thing (220 comments)

TheRaven64 says there are a million people with the same clearance level and asks what are the chances that none are Chinese agents. You counter by making them all sysadmins who are all* stealing other people's credentials. And you think he's using hyperbole?

The opposite of none is at least one, not all of them.

* I know you don't use the word "all" but it is clearly implied in what you wrote. Compare the following: "There are a million people who have cancer." and "There are a million people, some of whom have cancer."

Silk Road Shut Down, Founder Arrested, $3.6 Million Worth of Bitcoin Seized

CanadianRealist $3.6 Million Bitcoin Seized (620 comments)

Will the government try to redeem these bitcoins? Wouldn't that be like saying that they accept that bitcoin is valid? (Of course they could be hypocrites and say that bitcoin is completely invalid and redeem them anyways.)

It would be neat if all the seized bitcoins could be identified and recorded as being worthless now.

Snowden Strikes Again: NSA Mapping Social Connections of US Citizens

CanadianRealist Re:news media has lost interest? (513 comments)

If the CEOs were really interested in reporting on this they could make their own news with a sting operation. Plan to do a few "embarrassing" searches, document them ahead of time with a few high profile lawyers then do them. When the NSA acts, you reveal it all on your news programs.

New Ship Will Remain Stable By Creating Its Own Inner Waves

CanadianRealist SWATH doesn't require power (43 comments)

Small Waterplane Area Twin Hull (SWATH) is a design that minimizes the effect of the waves. Most of the volume that supports the ship is below the level of the waves, making it very stable. The stability comes from the hull design, so it doesn't require any power and the stabilization isn't prone to failure like an active system.

Here's a short video of a SWATH ship in rough seas, with a regular hull ship for comparison. I'm pretty sure this is the one that I saw in a documentary about the design. They showed a glass of water sitting on a table in the SWATH ship, not spilling. I'm pretty sure that the glass would go flying in the other ship.

Report: By 2035, Nearly 100 Million Self-Driving Cars Will Be Sold Per Year

CanadianRealist Re:For the love of Junior Johnson... (325 comments)

Airbags are passive: drivers don't have to do anything at all, they just work.

Automatically. Which is the point that was being made in the post that you originally replied to.

The question of active or passive is a separate issue and is complicated by the government's way of defining it. (Which seems backwards to me.) I would expect active/passive to refer to the device itself, rather than the user's interaction with it. The way the government defines it a self driving car is pretty much a passive device. A rock is an active device - it doesn't do anything unless you pick it up and throw it. Imagine a fully automatic predator drone that takes off, locates a target and attacks completely automatically. That would be labelled a passive device. I don't think those labellings match the usual interpretations of those words.

Report: By 2035, Nearly 100 Million Self-Driving Cars Will Be Sold Per Year

CanadianRealist Re:For the love of Junior Johnson... (325 comments)

Red herring. Airbags are passive safety devices, not a device to automatically do something the driver had to do previously.

Sounds more like red herring argument to me. Deploying automatically, at high speed, at the instant an accident occurs is not at all passive. A seat belt is passive, once the driver attaches it. (At least the older style fixed ones were. Modern ones which lock only in response to a sufficient pull are questionably passive.) And as for not being something a driver had to do previously, they could have been set up as such, but I'd bet they would almost never have been used at the instant when needed since human reaction time is pretty poor. It would probably have been better for the human to try to avoid the accident in the first place.

GMO Oranges? Altering a Fruit's DNA To Save It

CanadianRealist Re:nature and consumers (358 comments)

Are you sure you replied to the correct post? I said absolutely nothing in favour of GMO plants and I'm pretty sure I didn't say anything that calls for the hostility in your post.

I was commenting on the difference between wild plants versus cultivated ones. That was the point of the GP of my post, but missed by the parent post which compared two different cultivated plants - the heirloom versus the mass produced one.

GMO Oranges? Altering a Fruit's DNA To Save It

CanadianRealist Re:nature and consumers (358 comments)

He said very clearly what he was talking about:

Show me a wild tomato that can grow without human cultivation and is as tasty as any modern tomato.

Heirloom tomatoes are modern, just not mass produced. They are still the result of people using selective breeding to improve on what they found in nature. Wild means what grows naturally, on it's own. Consider for example wild bananas from which people cultivated modern bananas.

Med Students Unaware of Their Bias Against Obese Patients

CanadianRealist Re:Unconscious? (446 comments)

You raise a valid point. My reply was about assessing their unconscious feelings. Maybe it would be better to say that they are unaware of their bias, or even worse are willing to lie about it.

Med Students Unaware of Their Bias Against Obese Patients

CanadianRealist Re:Implicit Association (446 comments)

I can really only answer for myself, which is what that statement was about. I found out that I had biases that I was not aware of. At least some associations gave me much more trouble than other ones did, and I don't have any other explanation for that. For some I didn't even need to see the reported times, I was aware of the difference while doing the test.

Maybe everyone else is aware of their biases and is simply not willing to admit them, but I doubt that. I suspect that for these biases:

reality > what people will admit > what people are aware of

New catalyst allows cheaper hydrogen production

CanadianRealist CanadianRealist writes  |  about a year ago

CanadianRealist (1258974) writes "Electrolysis of water to produce hydrogen is very inefficient without the use of a catalyst. Unfortunately catalysts are currently made of crystals containing rare, expensive toxic metals such as ruthenium and iridium. Two chemists from the University of Calgary have invented a process to make a catalyst using relatively non-toxic metal compounds such as iron oxide, for 1/1000 the cost of currently used catalysts.

It is suggested this would make it more feasible to use electrolysis of water to create hydrogen as a method of storing energy from variable green power sources such as wind and solar."

Cow manure generates electricity and big savings

CanadianRealist CanadianRealist writes  |  more than 4 years ago

CanadianRealist (1258974) writes "Manure from 600 cows is digested in a 16 foot deep, 70 foot diameter tank to produce methane gas which is then burned to generate electricity. The system generates enough electricity to power the farm and a dozen neighboring homes and still some back to the grid. Generation also creates heat which is used to heat the digester, farm buildings and water. The $200 000 per year savings are expected to pay for the system in 5 years or less. As a side benefit, the digester also reduces 98% of the odor."
