The Largest Ship In the World Is Being Built In Korea

dj245 Re:Ho-lee-crap (272 comments)

I suspect it is a space limittion more than anything that prevents most western shipyards from building multiple ships that size. ...... Cheap labor long ago reduced shipyards in most western countries to building military ships and some extremely spicalised or luxury ships.

You just contradicted yourself. Western shipyards aren't limited on space. If you have the demand, you can always get more space / capabilities / labor / raw materials. They are limited by demand.

The Largest Ship In the World Is Being Built In Korea

dj245 Re:Ho-lee-crap (272 comments)

No, when you are working on such a massive scale they really aren't simpler, the engineering and sheer weights alone are astronomical.

Not really, the numbers are larger but the math is very well understood. This is a very mature industry, perhaps the oldest manufacturing industry in the world. People have been building boats for thousands of years. Ship's aren't redesigned every time one is built either. The bulk of a ship is the exact same "U" profile. Design it once, copy it all down the length of the ship. The bow and the stern are the only complex parts, but contribute little to strength. The bow and stern are generally proven designs which are taken "off the shelf" and adapted to the application with only slight changes. Chopping off the back end of a ship (accommodation, engineering, and propulsion area), refurbishing it, and welding it to a brand new ship hull is not uncommon. Unlike with pleasure craft and cars, "style" has approximately 0 design influence in large ships. Everyone is honing in on the most hydrodynamic designs and you can't copyright the math which describes the curves on a ship.

I'm onboard the Tolteca right now, built in 1954/1955. When we were in drydock, the only difference between this ship and ships built much more recently is the distinct lack of a bulbous bow, and the use of diesel propulsion engines instead of a steam turbine.

The Largest Ship In the World Is Being Built In Korea

dj245 Re:inbuilt scrap capabilities (272 comments)

Ship breaking is very tedious process: http://en.wikipedia.org/wiki/S... Why no to build-in capabilities for a ship to break itself easily?

Because it adds cost. When a ship has reached the end of its useful life, it's value is approximately the (ship mass * the price of steel). Labor in 3rd world countries is so cheap that it doesn't factor into the equation much. You would never see any return on that investment.

dj245 Re:That's bananas! (272 comments)

enough space to transport 864 million bananas I'm so happy to see we have finally converted to the banana scale. I've been waiting for this since horsepower was invented!

Maybe someone thought they were being clever, but in reality they are just very ignorant. Bananas are almost always transported by vertically-integrated companies who own their own ships. It's like this because generally Bananas are coming from a port which has little to ship aside from bananas, and the bananas generally go to a small number of special ripening warehouses where they ripen for a while. They're a kind of special cargo, not a general cargo to be put on any container ship. Just as an example, Dole owns at least 6 ships. Chiquita and the other banana companies almost always have their own ships too.

Despite Patent Settlement, Apple Pulls Bose Merchandise From Its Stores

dj245 Re:lol (328 comments)

Bose's direct/reflective (I think that's what it's called) technology in it's early 801, 802 and some other models created a large sound-field with a large sweet-spot, or almost no sweet-spot. (A sweet spot is the place the listener sits to get the full stereo effect). This can be, hmm, I'll use the words very different and seductive...........

Gee, thanks a lot. You just made good stereo seem terrifically exciting. I have single sided deafness and can never expereince stereo. Nobody, even doctors or audiologists, ever really explained what I am missing out on. Maybe they were being kind.

FBI Says It Will Hire No One Who Lies About Illegal Downloading

dj245 Re: Ok, but (578 comments)

Women aren't looking for a yes/no answer when they ask if their clothes are unflattering. They are trying to open a conversation on the subject of their entire look, including what is working, what is not working, and what elements are working together well, or clashing. They are not looking for you to "kill their question" as efficiently as possible. They are trying to invite detailed discussion and analysis.

No Nobel For Nick Holonyak Jr, Father of the LED

dj245 Re:The Nobel Prize Committee blew it (276 comments)

Sure, but what if a red LED is a natural evolution while blue LED, once thought impossible is the true revolutionary idea?

Well, maybe they looked at impact. For decades, LEDs were only used for status lights, power lights, and some other things. Switching from mini-incandecent bulbs for these purposes didn't really change much in the grand view of things. Switching out household lighting from incandecent to blue/white LED saves thousands of megawatts of electricity, and enables many impoverished people to have electric light for the first time ever. I went to North Korea this year and even in very remote areas with clearly impoverished people, solar panels, batteries, and LED lighting were very common. Bringing light to the people like that would be a lot more difficult without LED lighting.

And if you think that inexpensive, efficient lighting is not a big deal, try living without it for a week. The availability of inexpensive lighting has become so embedded in Western society that we can't imagine life without it. Think about what that means to the billions of poor people all over the world who are getting, or have gotten it, for the first time.

Ask Slashdot: How Would You Build a Home Network To Fully Utilize Google Fiber?

dj245 Re:no, there isn't. F'n 1% er buys a house with fi (279 comments)

I've grown very tired of my apartment complex's saturated wireless spectrum (both 2.4 and 5) because everyone is right on top of each other and every apartment has one of three routers from the different ISP options.

Interesting. I didn't know that it was really possible to saturate the 5Ghz spectrum. 2.4 is easy with only having 3 non-overlapping channels, but 5Ghz has over twenty, and by default none of the channels overlap.

Last time I was in a dormitory I found over 20 networks within scanning range of the guy's room, but there was only ONE other network on the 5Ghz spectrum.

Read what the parent wrote- " the poor penetration of 5 GHz". Meaning it does not go through walls or other obstacles very well. Which is true. And a problem with deploying 5Ghz networks.

Texas Ebola Patient Dies

dj245 Re:The Conservative Option (487 comments)

I have two pasports, as do many people. http://edition.cnn.com/2012/07...

It is nearly impossible to estimate how many U.S. citizens have dual -- or even triple -- citizenships, says Michael A. Olivas, an immigration professor at the University of Houston Law Center. [...] The number is likely well over 1 million, he says, and is probably several times that.

So, I can use one passport to go in and out of Cuba, Africa, Iraq, or wherever, and use the US passport for going in and out of the USA. How would they track that?

They can't even track a single US person with a single US passport. I took a trip to North Korea earlier this year. My father is an immigration inspector and looked at my record. According to the US government, I had a pleasant 10 days in Beijing.

The Greatest Keyboard Ever Made

dj245 Re:Still being made... (304 comments)

Biggest problem for me is that I'm in the UK and the layout is different from the standard US-style keyboards (and far superior :) )

So Deck, Code and similar new manufacturers just don't cut it.

Have you not been on the Unicomp website? They will custom-build pretty much any keyboard you want, with or without windows keys, with a large choice of language layouts (UK included).

Why Do Contextual Ads Fail?

dj245 Re:Hmmm ... (249 comments)

Personal data harvesting for contextual ads and content should be a beautiful thing. They do it privately and securely, and it's all automated so that no human being actually learns anything about you.

So, are you shilling for the ad industry, or do you really believe this is supposed to be a good thing?

Sorry, but I'm not interested in your ads of any form, I'm not interested in targeted ads at all, and I don't trust the entities gathering this information with any of it, or that they won't abuse it.

So, screw your contextual advertising. I will continue to block every ad tracking site I can identify, block your ads, your web bugs, and everything else I can.

If you think letting unknown third parties collect information about you, put cookies on your machine so they can know everywhere else you go, run scripts, run Flash ... or pretty much anything else ... is a good idea, then you're either clueless, or getting paid from this.

I think your entire premise is flawed, or dishonest.

It could be a good thing. But usually it is abused. The ideal scenario is using targeting advertising to push someone over the edge when there was a 70+% chance of buying something anyway. If I go to Home Depot on a hot saturday morning, getting a text message coupon for the Dunkin Donuts on my way home would be great. Sadly, many advertising people are still stuck in 1960s and don't understand how to do unobtrusive advertising.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

dj245 Re:LED lighting (243 comments)

"CREE is selling 60w bulbs for $9"

Wow, a 60w LED bulb - how many lumens does that put out?

Feit electric has a similar 60W bulb for about $9 and it puts out 850 lumens. I bought a pile of them at Costco. With a $6 per bulb local utility company subsidy (Connecticut) they were $3 apiece. I like the color temperature a lot. I should have bought more. Also- I have been using 1 to 2 bulb "Y" adapters in any fixture where they will fit. Since LED's use so little power, there is no worry at all about exceeding the amperage limit of the wiring. Let it be bright!

Cyanogen Inc. Turns Down Google, Seeing $1 Billion Valuation

dj245 Re:1 B$ for open source software ? (107 comments)

CyanogenMod is missing the boat by being blinded by the *potential* for more cash. The ture reality is that Google's offer is the best they will get, and they fucked it up. Google will offer them much less when it becomes obvious that CyanogenMod made a mis-calculation.

I was waiting for someone to say this. We're clearly in a tech bubble. Making a business out of CyanogenMod would mean trying to out-google google, while at the same time relying on many of google's own services! They are fools for not taking the money and running.

A Garbage Truck That Would Make Elon Musk Proud

dj245 Re:Good video on this (174 comments)

Technical details on the turbine include; 200 lbs, 250 hp, 40,000h service life between overhauls (13+ years @ 8h / day.) The turbine has air bearings to eliminate wear, which implies a gas generator/power section arrangement to drive the generator, I believe.

A gas turbine is composed of two sections- a compressor and a power turbine. Probably they are using some compressor bleed air for the bearings (which is expensive, effeciency-wise). It still doesn't make sense to me though. Diesels in that size are much more efficient, more tolerant of abuse, more tolerant of contaminated fuels, and a lot cheaper to maintain. The only reason to use a gas turbine is when weight REALLY matters. We're talking about a garbage truck here. 100-200 more pounds for a diesel engine isn't going to be noticed. It may even balance out since a tank of diesel can likely be made lighter than a tank of compressed LNG.

Solar Could Lead In Power Production By 2050

dj245 Re:Electricity from Oil? (167 comments)

That's messed up... Only 40 years of oil supply left, compared to 160 years natural gas and 400 years of coal.

No electricity should be generated via oil right now, and definitely not in 2050.

The amount of electricity generated using oil in the US is less than 1% and has been that way for decades. Oil is too expensive to burn compared to any other way of making electricity. The 1% used in the USA is generally in emergency cases where there is a heat wave / cold snap and demand outstrips the normal supply.

Lost Opportunity? Windows 10 Has the Same Minimum PC Requirements As Vista

dj245 Re:It's fast enough for office use (554 comments)

I am working for a company with 6000+ desktops. I do not understand why our client engineering is rolling out faster hardware every year. 95% of all office workers need MS office, a browser and email. Most of the home users just need a browser these days. Those core i7 are just idling around heating office space.

I have now started rolling out 200 dollar desktop hardware (zotac). Which could really become a problem for microsoft. The windows licence price tag looks really expensive with these hardware prices.

Office problems are solved, we do not need faster hardware. And microsoft is manly making money from, *drumbeat*, office workers.

Best -S

I surely hope you are not also one of those awful IT people that keep purchasing spinning disks for user computers. If you do the math for what an employee is worth, and think about how many minutes they are waiting for their computers to boot/shutdown/open a program, having high-end hardware is often a no-brainer. $2000 in hardware cost is dwarfed pretty quickly by a $100k salary employee twiddling their thumbs for 5 minutes every day waiting on their computer.

End of an Era: After a 30 Year Run, IBM Drops Support For Lotus 1-2-3

dj245 Re:Lotus 1-2-3 (156 comments)

Ok, that I know of Lotus was never on Apple... wasn't that Visicalc?

Anyways... when I was a kid, my father brought home a Commodore Vic20 and said "Son! This is the future!" and told me to figure out how to plug it into the TV. I'll not lie... to me it was a video game machine for years. The command line reminded me of exploring some cave... the directories different tunnels, etc... I was a kid.

But as the computers got better and I eventually found myself on an Apple IIe and a Compaq PC it got more interesting. And what finally made me realize what computers could do was when my dad brought home copies of Lotus and Visicalc. I would sit for hours making spreadsheets with formulas in pale monochrome ASCII. You could change something in one cell and watch all the other cells change in response. Prior to that I had no idea what programming even was... or how variables and functions worked. Those first spreadsheets are what made it all real to me. I thought it was amazing. I put my famillies finances on it. I budgeted my allowance. I made rudimentary war games. Really, Lotus (because I always liked the PC better) is what finally made me realize computers were important, and it was something I wanted to do.

Thanks Lotus!

I heard that when accountants first saw demos of Visicalc, many of them literally broke down in tears when they realized how much of the "boring" parts of their job were going to be eliminated.

Ask Slashdot: Is It Worth Being Grandfathered On Verizon's Unlimited Data Plan?

dj245 Re:Boost mobile (209 comments)

I have to suspect you have never experienced Verizon's coverage area and reliability.

Like every carrier, it varies depending on where you are. I used to swear by their coverage and reliability but then I found many places where it just fell flat. The best coverage carrier is the carrier who has coverage where you are or need to be, not the carrier who claims to have covered x% of a map.

HP Introduces Sub-$100 Windows Tablet

dj245 Re:How does it handle Pinterest? (182 comments)

The laptops are based on the Celeron N2840, with 2GB of RAM. I can't seem to find much in the way of benchmarks; but I suspect that they are surprisingly adequate. What is a bit surprising is that the the N2840 has a quoted tray price of $107, so either Intel is cutting HP one hell of a deal, or I don't even want to know what HP cobbled the rest of the system together from...

I don't think that tray price has much basis in reality. The "$107" N2840 looks, at least on the face, to be not vastly different from the "$86" 1037U. If Biostar can sell a motherboard + 1037U + heatsink + fan for $79.99, it doesn't take much of a stretch to think maybe these prices are just "list" prices with no basis in reality. Biostar is just selling a bare motherboard so there can't be any Microsoft kickbacks or ad revenue.
