Solar Powered Technology Enhances Oil Recovery

mc6809e Re:Renewable (82 comments)

Using renewable energy to tap unrenewable energy... Seems not really enduring. Why not just use directly the renewable energy in first place?

Because oil isn't just used as energy, though it often is.

Petroleum is a miracle substance from the standpoint of its chemistry. It would be hard to imagine modern life without all the chemicals and materials petroleum makes possible.

Burning such a flexible, important substance as fuel is terribly foolish.

IT Job Hiring Slumps

mc6809e Re: GIst of the problem is ... (250 comments)

I think his 50% tax burden number comes from including Federal income and payroll taxes, State taxes, and local taxes.

That's probably correct only for highly paid professionals that get most of their income by selling their skills. Anyone with income that comes from wealth isn't paying anywhere near that.

The tax code in the US at all levels is incredible stupid.

But the 50% number isn't connected too terribly much with the lack of hiring, though. If you ask a business people why they aren't hiring many will tell you that they just don't have enough time to both run their business and worry about all the extra bureaucratic hassles that come with employing someone -- that might include paying some taxes, but it also includes liability and regulatory concerns.

Employing a new worker is like walking through a minefield. You might have seen job advertisements asking only for those that are currently employed. This is an attempt to avoid all those disasters that come with hiring the wrong person.

Islamic State "Laptop of Doom" Hints At Plots Including Bubonic Plague

mc6809e Re: But is it reaslistic? (369 comments)

The only Bacteria that are scary are anti-biotic resistant ones, all the rest can be cured with a dose of anti-biotic.

Don't be so dismissive.

I realize the plague is so dark ages and that we have antibiotics, but from 1990 until 2010 the overall mortality rate was 11%.

People still die even with antibiotics.

Islamic State "Laptop of Doom" Hints At Plots Including Bubonic Plague

mc6809e Re: But is it reaslistic? (369 comments)

The plague exists in the wild in many western states of the USA.

Colorado just had four cases in the past few months.

Why Women Have No Time For Wikipedia

mc6809e A willingness to fight (579 comments)

Men in general seem to have less tolerance for what they perceive as error and a greater willingness to fight to correct error.

That's not the say that men are more often correct than are women. They just seem more eager to do battle, even if it is from behind a keyboard.

Anyone that's been involved in an edit war of wikipedia knows that the winner is often isn't the one with the best grasp of the facts, but it's the one least willing to give up the fight.

Companies That Don't Understand Engineers Don't Respect Engineers

mc6809e It works the other way around, too (371 comments)

Many engineers don't understand that business people are engineers of a sort, too.

What we all should do is realize that we're all part of a team that can't work without the participation of everyone. Mutual respect is key.

Many skills are needed if a firm is to survive.

For Fast Internet in the US, Virginia Tops the Charts

mc6809e Re:Switzerland (98 comments)

In Switzerland the slowest speeds you commonly get are about 15 Mbits/s...

And yet the report cited shows that only 45% have access to speeds above 10Mbps and 23% of access to speeds above 15Mbps.

Five US states have more people above 10Mbps than Switzerland.

And one of those states by itself, New Jersey, has almost a million more people.

No 4g available? I'm using a Verizon 4g access point from a horse farm in the middle of nowhere and Speakeasy's speed test gives me 10.46Mbps down/7.53Mbps up.

Cable Companies: We're Afraid Netflix Will Demand Payment From ISPs

mc6809e Re:What? (200 comments)

Yeah, i don't see how their supposed 'netflix is going to extort us' scare is supposed to work. Everything I remember about how the internet works pretty much invalidates the idea.

I think they're looking at how cable companies have to pay content providers to broadcast their content.

Disney, ESPN, CNN, etc all charge the cable company for their content. If the cable company doesn't pay, then their customers don't get the channels.

Will this happen with websites or Netflix? It doesn't seem possible, yet it's hard to know just where all this is going.

Consider facebook. What would happen if suddenly facebook demanded an ISP pay them for access by the ISP's customers? Who would the customers blame? Would they simply give up on facebook or would they hound their ISP to pay up?

Experiment Shows People Exposed To East German Socialism Cheat More

mc6809e Re:let me correct that for you. (619 comments)

there was no socialism in east-germany. there was none in east-europe. that was fascism with a tiny bit of communism-appearence thrown in. socialism is found in scandinavia, belgium, netherlands, france, and the former western-germany.

Most Western European countries are mixed economies, mostly capitalist, with some socialism, and a welfare state.

East Germany and the Soviet Union really bought into the idea of Socialism: the state owned everything. Private property was outlawed. You could go to jail for making a profit.

The East Germans were so committed to the idea that the state owned everything that they believed they had a right to build an enormous wall to keep the governments property (people) from escaping to the West.

'Rosetta Flash' Attack Leverages JSONP Callbacks To Steal Credentials

mc6809e Very clever (68 comments)

Reminds me a little of some work done by Terje Mathisen, an expert assembly language programmer. Not exactly that same as the exploit, but probably interesting to a few slashdotters. I'll let him describe it:

"The most complicated code I have ever written is/was a piece of executable text, in order to be able to send binary data over very early text-only email systems:

"Minimum possible amount of self-modification (a single two-byte backwards branch), a first-level bootstrap that fits in two 64-byte lines including a Copyright notice and which survives the most common forms of reformatting, including replacing the CRLF line terminator by any zero, one or two byte sequence. This piece of code picks up the next few lines, combining pairs of characters into arbitrary byte values before flushing the prefetch cache by branching into the newly decoded second-level bootstrap. (Everything uses only the ~70 different ascii codes which are blessed by the MIME standard as never requiring encoding or escape sequences.)

"This second level consists of a _very_ compact BASE64 decode which takes the remainder of the input and re-generates the original binary which it can either execute in place or write to disk.

Teaching College Is No Longer a Middle Class Job

mc6809e Re:Administrators (538 comments)

In all aspects of education, from primary school to university, the growing swarms of administrators soak up the budget. In some school systems, they vastly outnumber the actual teachers, have better pay, and yet contribute nothing to the operation of the schools.

Don't forget those in the construction industry. Like administrators, they contribute where it counts: in the voting booth where they help elect those that will continue to increase spending on that abstraction "education" rather than on actual educators.

Will 7nm and 5nm CPU Process Tech Really Happen?

mc6809e Re:For a sense of scale (142 comments)

There are other advantages to shrinking components. Higher clock rates become possible.

You'd think so, but the problem is global interconnect. Not gates. It was all the way back at the 250nm node when interconnect and gate delay were about the same.

At the 28nm node, wire delay is responsible for something like 80% of the time it takes for signals to work their way through a circuit.

And it some cases inverters are actually used to help signals propagate more quickly down long wires. In other words, long wires are so slow compared to gates that adding gates can speed things up!

Wireless Industry Lobbying Hard to Keep Net Neutrality Out

mc6809e Re:some level of fraud or deception (85 comments)

I believe many ISPs are actively sabotaging customer's connections to some of the internet's content

They don't have to. The protocols we use are more than capable of screwing with things.

Consider TCP: the protocol is BY DESIGN meant to exponentially increase the amount of data dumped on a link until it overloads and begins dropping packets. TCP then throttles for a little while and then soon goes back to bashing the network with packets until it breaks again.

Teacher Tenure Laws Ruled Unconstitutional In California

mc6809e Re:You make it... (519 comments)

Oh, it's a bad thing, depending on which way you look at it. For union busters this means you can finally sacrifice the weak and infirm on the altar of efficiency.

Wait. Are you talking about the children or the teachers?

America 'Has Become a War Zone'

mc6809e Don't worry--the crime rate is sure to go up again (875 comments)

Well, maybe.

Many of the worst and violent crimes are committed by men age 16-24.

Now look at this.

Notice that nice peak in the crime rate around 1992? Many of those crimes were committed by people born in the 60s -- a turbulent, uncertain time, and the 70s -- a rotten decade with a corrupt or weak presidents, increasing unemployment, inflation, and plenty of other rottenness.

I don't think it's too much of a stretch to believe that that sort of environment helps turn some children into violent criminals.

We have in some ways similar situation today. While some groups seem to be enjoying the recovery (baby-boomers, especially) many others are struggling. Young people -- those forming families right now -- have been left behind.

And I expect children being born into that world are having a tough time -- and in 16-24 years, we'll start to see the consequences.

New Car Can Lean Into Curves, Literally

mc6809e But it gives the driver the wrong impression (243 comments)

Drivers depend on feedback from the car to help them make necessary adjustments.

If a curve isn't banked enough, the car shouldn't fool the driver into thinking that it is banked enough.

That feeling one gets when the car leans towards the outside of the curve is telling the driver to slow down!

Rising Sea Level Could Put East Coast Nuclear Plants At Risk

mc6809e Re:Where does 7 feet of water come from? (323 comments)

Water like other materials expands when it gets warmer.

Just a nit-pick, but water's maximum density is actually at about 4C.

That means as it cools below 4C, it begins to expand again. If it didn't, ice wouldn't float!

As NASA Seeks Next Mission, Russia Holds the Trump Card

mc6809e Re:Eric Burger asks, how did it come to this? (250 comments)

And that little fact is almost entirely due to Congress' inability to think past pork and the next re election cycle.

So much of the budget is off-limits (social security and medicare) that the only areas left vulnerable to cutting are things like NASA.

The USA has locked itself into forced spending in some areas and it's squeezing other areas.

Bad news: Bertha is damaged

mc6809e mc6809e writes  |  about 7 months ago

mc6809e (214243) writes "Officials on Friday announced the seal assembly is damaged. Bertha may be shut down for several more weeks as workers fix damaged seals that protect the drive system that spins the giant cutter. The revelation comes two months after the drill failed to grind ahead and operators shut it down. The machine known as Bertha tweeted in December that she was doing fine, just facing an obstruction. An 11-day inspection in January found no big obstacles, turning engineers’ attention inward. The ongoing investigation — which includes an influx of staff from drill maker Hitachi-Zosen — could take up to two weeks before the Seattle Tunnel Partners (STP) contracting team issues a strategy to repair and restart the machine."

F.C.C. Bars Lightsquared from Using Airwaves

mc6809e mc6809e writes  |  more than 2 years ago

mc6809e (214243) writes "A proposed wireless broadband network that would provide voice and Internet service using airwaves once reserved for satellite-telephone transmissions should be shelved because it interferes with GPS technology, the Federal Communications Commission said Tuesday. The news appears to squash the near-term hopes for the network pushed by LightSquared, a Virginia company that is majority-owned by Philip Falcone, a New York hedge fund manager."

Killed for Tweeting: Mexico's Drug War Has Two Mor

mc6809e mc6809e writes  |  about 3 years ago

mc6809e (214243) writes "Twitter has become deadly serious in Mexico, where two people were allegedly murdered for denouncing a drug cartel on the social network.

In Nuevo Laredo, Mexico, a man and a woman were found hanging from a bridge by their hands and feet. An examination of the bodies showed signs of torture, and the pair is thought to have been beaten and killed by a powerful local drug gang, then displayed to send a message to citizens who might want to publicly renounce the group.

Attached to the bodies were two signs, one of which read “This happens for denouncing,” according to CNN. One of the notes also had the names of two blogs, Al Rojo Vivo and Blog del Narco."
