US Air Force Selects Boeing 747-8 To Replace Air Force One

Hadlock Re:Not going to disappear quickly.... (283 comments)

Old 747s have terrible fuel economy which is their highest operating cost, plus they have to be completely torn down (seats out, overhead bins out) for a complete airframe inspection, engines rebuilt etc every 6 years or so and it costs millions of dollars to do this "frame off restoration" with qualified FAA certified mechanics. After the fourth or so complete restoration the cost-benefit ratio slips in favor of buying a whole new airplane. This isn't like buying a pickup truck for personal use which you can just drive until the wheels fall off, swap in a new rear axle and drive it another 500,000 miles without ever doing a proper inspection of the frame, wheel bearings, etc.
 
In addition to the major overhauls, they do slightly less major overhauls every 4 years, and they still do a full 2 day inspection every 18 months or so.
 
Eventually these old 747s get sold for a song because the maintenance to keep them flying isn't worth it. There's a 747 in the background at the Top Gear test track (which is a converted airfield) that is parked most of the time or used as a prop for movies but is still airworthy when someone needs an extra cargo jet, or needs to fly a football team to Australia or something for top dollar. But they're not economical for daily use by major commercial airliners anymore.

With today's ultra capacitors it seems like you could recapture 70% of the energy on the way down again. Maybe more.

TWEETHER Project Promises 10Gbps MmW 92-95GHz Based Wireless Broadband

Hadlock Re:Physics doesn't work like that. (54 comments)

Depends on the insulating effect of feathers! Birds have much higher heat tolerances than humans, 130F isn't too extreme for avians. Particularly if the feathers act to absorb and dissipate 95 ghz.

TWEETHER Project Promises 10Gbps MmW 92-95GHz Based Wireless Broadband

Hadlock Re:Physics doesn't work like that. (54 comments)

Apparently 95 ghz is the frequency they use to burn the skin in heat rays, it's energy is fully absorbed by the first 1/64" of skin. From Wikipedia "employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 ÂF (54 ÂC) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting damage."

So yeah, penetration would be poor at best, unless between towers, or from LEO/MEO SpaceX built satellites to rooftop antennas.

Justified: Visual Basic Over Python For an Intro To Programming

Hadlock Re:C# (648 comments)

How about Powershell? It has an ISE you can pickup and learn in less than 20 minutes. It takes about 2 hours just to get to the point where you're writing actual code. Powershell gives you full access to the .net library and runtime but the requirements to produce executable code are on par with Python. In fact Powershell looks a lot like "Python#" and IDLE.

Tiny Fanless Mini-PC Runs Linux Or Windows On Quad-core AMD SoC

Hadlock Re:Perhaps at last an affordable mini PC? (180 comments)

You can get an ASUS X205 with Windows 8.1 preinstalled for about $200 shipped if you shop around, $179 if you're willing to walk in to a Microsoft Store.
 
That said it's not three times smaller, it's three times less volume. It's only 2cm on a side smaller, not much bigger than a Raspberry Pi B+, which let's be honest, isn't game-changing at this point. 2012 was a long time ago.

Tesla To Produce 'a Few Million' Electric Cars a Year By 2025

Hadlock Re:Tell me it ain't so, Elon! (181 comments)

Yeah retail salespersons are kind of dinosaurs at this point. You can't technically buy a car on Amazon but you can buy a road legal (in some states) scooter there. Inertia is the only reason you can't order a new Toyota Camry or Prius on Amazon and have it shipped to your house. You can do it with used cars on Ebay at least.
 
I'm not sure jobs or tax revenue are a good reason to impede forward progress though.

Man Saves Wife's Sight By 3D Printing Her Tumor

Hadlock 3D models are incredibly helpful (164 comments)

I'm not a vet student, but I did spend a night helping one study the sinuses of a large animal (they split in to large animal (farm) and small animal (pet) specialties) and some of the learning materials are a little difficult to wrap your brain around, in particular how the sinuses (voids in the skull) exist inside the skull, how they connect (or don't) and simply where they are. The brain has enough trouble understanding negative spaces, even more trouble trying to conceptualize the winding, twisting 3D negative spaces you can't ever directly view without cutting apart a skull to do so. Even then doing so only gives you half the picture, and in negative space.
 
There are some videos online showing the sinuses in "positive 3D space" but it's still only a reference (Everyone is different) so I would imagine having a 3D positive space model of a tumor you've never seen and can't see without cutting open someone's head would be incredibly helpful, especially since you can't just buy off the shelf reference material for human tumors like you can bovine sinuses.

For the First Time In 3 Years, Investments In Renewable Energy Increased

Hadlock Re:Huh? (134 comments)

Solar is already on par with electricity prices (which are mainly driven by the pool-table flat price of coal) and solar is expected to be half the price of electricity in 15 years. And that's in the first year. That means you get back 100% return on your investment in the first year. The next 25 years are just gravy (assuming no hail storms and your batteries never wear out). If you live in a hot state nearly free electricity during the hottest part of the day means you'll have a very predictable and very low electric cost for 10 months out of the year (12 if you have gas heat).
 
What I'm saying is, solar is already cost-effective, but in 10 years even with dirt-cheap oil, solar will still be cheaper, and there's no global fluctuation in locally produced and consumed solar energy.
 
Energy independence = less need for global intervention in war-torn oil producing states.

Dish Introduces $20-a-Month Streaming-TV Service

Tumblr Co-Founder: Apple's Software Is In a Nosedive

Hadlock Re:Wrong way round (598 comments)

The hardware hasn't become less serviceable, it's that the hardware has shrunk to the size where it's not economical to break out the audio from the video, or the CPU from the audio and video, or the eithernet, disk controller, etc. As a result you end up with a tiny circuit board that costs pennies to produce, is easily maintainable and fits inside today's slim devices.

Museum's Adults-Only Nights Show That Alcohol and Science Are a Good Mix

The last event I went to like this, 12 oz beers were $5 and cocktails were $6. Which for downtown Dallas is average, if not slightly below the median price. And it was pretty fantastic. As a vet, an engineer and a computer programmer we had a pretty fantastic time, A+ would go again. Let the schoolchildren enjoy the museum during the day.

Uber Must Submit CEO Emails

Hadlock Re:Uber's in a completely different market (183 comments)

Taxis can pick up fares on the street. Private cars have to be arranged beforehand. This is a BIG distinction between taxis and Uber. BIG BIG. Taxi companies are terrible at arranging pickups, which is what Uber has replaced. The problem is that each Taxi driver is "independent" and has no quota of X% prearranged fares they have to pick up each week/month. If they want to sit at the airport and wait for a fare, they can. If they want to sit outside of a hotel and wait for a fare, they can. An uber driver has to take any fare they get selected for, and if they decline X%, they get a warning, and after that eventually lose their contract. Which means uber drivers actually pick you up.
 
In a lot of less dense American cities, Uber is something like 12x faster than hailing a cab. If a taxi even drives down your street once an hour. I'm near a major bar district and Taxis here only drop people off, then go looking for fares by the hotel again. Have you ever tried using a Taxi in an american city outside of the most dense urban core? They don't work. They're broken.

Uber Must Submit CEO Emails

Hadlock Re:Uber's in a completely different market (183 comments)

The first five miles around downtown are solidly urban, and Taxis fill a specific (and important!) gap between public transit and private transit. If the Taxis don't owe the city anything, why are they a protected and regulated monopoly? Why not just disband the taxi system entirely and let services like Uber replace them in cities with urban cores smaller than SF and NYC?

Uber Must Submit CEO Emails

Hadlock Re:Uber's in a completely different market (183 comments)

I wish(!) My car developed a short last winter and I switched to commuting by bicycle most days, Uber on the rainy/colder days (somewhat rare here in Dallas). It's about $6.50 one way to my office downtown from my house. I smashed up my hand (partial cut to my index finger's extendor tendon) and ended up taking Uber every day for three weeks while I was unable to ride my bike. I spend about $90/month on uber rides in the winter, it's pretty fantastic. If the city of Dallas were to ban Uber, I'd buy another car and go back to driving on cold rainy days. Between gas insurance and parking downtown, Uber actually comes out about $0.70 a day cheaper than owning a car full time. And I don't have to drive in rush hour traffic, so I can respond to work emails "in transit" which means I can leave the house 15 minutes later than normal, and my correspondence is already caught up for the morning before I walk through the door.
 
Uber is reliable and someone always shows up in 5 minutes. I've never had a taxi arrive less than 45 minutes after I called for one. Here in Dallas taxi's primary purpose is going between downtown and the airport. With Uber I've been able to finally write off my main reason for owning a car - reliable transportation, and do it in a cost effective manner.

Uber Must Submit CEO Emails

Hadlock Uber's in a completely different market (183 comments)

Everyone I know uses Uber, at least once a quarter. It only takes 5 minutes for an Uber to arrive and typically it only costs $5 to get a ride back to your car, or $20 to get a ride back home. When calling a taxi, you may or may not have someone arrive within an hour, especially during peak hours. What's the point? If it takes an hour for a Taxi to arrive and you're going less than 4 miles, it's faster to just walk.
 
Taxi companies want the Uber business, of course they do. But Uber customers hate taxis. They're dirty, filthy, never arrive on time and dealing with change/tips is a real hassle. Especially if it's late and you've been out with friends all night. If Uber disappeared from my city I'd just stop using similar services. Uber makes it just this side of bearable. Taxis are a fucking disaster and unless I'm headed home from the airport in a foreign city, I doubt you'll ever see me in one. If Uber disappears, so does my desire to use "taxi" services.

i thought i'd go ahead and write one more article in here, since the other article is so blah and that's what comes up when you click on my journal. this slashdot journal system really was a stillborn project; i'm not sure if they keep it around because cmdrtaco and friends still use this thing, or if there's actually people who use this on a regular basis. either way, this is the first post in four years or so from me; i was using lj before, and will continue to do so despite compeitors like myspace. here's to another 4 years of not posting in this.

LC case mods....

Hadlock Hadlock writes  |  more than 12 years ago

Well fuck this. I'm getting my fucking work done; I'm just bored and relaxing. I would have this fucking shit done by now if I hadn't goddamned fucked up with the whochamacalit. Chapter 7 instead of chapter 5. Grrrr. Spring break in like, 3 days. Sigh. Umm what else to talk about? After looking at case designs for my mac, I looked at the case for my mac, and specifically noticed that the fan on the bottom sucks in A LOT of freaking air. Wow. So that limits my positioning of the fan. I guess I could mount the fan as an exhaust fan pressed directly up to the power supply, as the only thing I really need to worry about is the powersupply, it gets fairly warm without any decent airflow. Warm isn't really a problem; but I want things as cool as possible. Maybe mount a heatsink or 9 on it? Hmmmmmmm. SCSI drive is just going to run hot regardless. Put it near the convection vent on the bottom, and let the cool drafts passively cool it. I don't really have to worry much about the motherboard, as it doesn't create enough heat to warrant active cooling. If it's not warm enough for apple engineers, it's not warm enough for me. Hell, it's $5 hardware. Crazy that it used to be worth $1200. Crazy. I really need to go get that $5 LC II from allen, and build a mockup of what I'm going to need to do for my final case design. At least if I fry that hardware, I still have a backup or 2. The only things I'm worried about are my HD and NIC card; the rest are pretty easy to get as salvage. Well I have an extra hard drive, so I guess all I need to do is buy a spare NIC card and I'm set. Some foam on the lid and back would probably provide decent sound insulation. In the final model made of aluminum and plexiglass, I could probably make some metal mounts and epoxy them to the inside of the aluminum cover, and then have the hard drive pressed against the lid. I'd need a slightly longer SCSI cable, so I don't tear up the motherboard when I open the lid? Internal lighting (blue neon light) would be bad-ass. Need to work on a way to run power cables up to the case....hmm. possibly that external SCSI CD rom drive's powersupply; that could potentially power both a second HD and/or a neon light. I could power it off of the LC's powersupply, but that would really just be overtaxing the power supply and a dumb design flaw on my point. I guess the dealy-o (yo), would be be to have a tube of some sort carry the power cable for the LC, 12 DC wires running up from a wall wart, and the RJ45 connection all inside a black or white, possibly light grey flexible tube. I think you can buy this at places like home depot. One idea I've been throwing around recently is that if I'm going to light this case internally, a frosted, or textured type of plexiglass, instead of the really hella clear plexiglass that shows srcapes and scratches really easily. I might have to sand blast my own? Hmm another idea- make the case out of clear plexiglass, and then tape down a cardboard picture of an apple, and sandblast the whole thing, removing the cardboard to give a relief of a clear apple. Kinda cool, but not exactly what I'm looking for. What I want is the front of the server case to look like the back of my powerbook - glowing white apple surrounded by brushed metal. I'd have to get the metal laser cut and then stick in some opaque plastic to be backlit. It'd be tight.

On an unrelated note, you could potentially cool a system with chlorine or argon gas, as they're element numbers 17 and 18 on the periodic chart. Instead of nitrogen, #8, with an atomic weight of 14; while chlorine and argon have weights of 34 and 39.8, respectively. Nitrogen makes up something like what? 72% of the air? 78% according to my envy sys book (I knew it would come in handy for SOMETHING. Sigh. CO2 and O2/3 make up something like 21% of the remainder. Nitrogen weighs the most, at 14, oxygen 12 and carbon not far behind. By effectively changing the density of the air, in theroy, that should increase the heat absorbtion factor. Of course, you can't just buy argon, BUT, you can buy an argon something something canister for your inert gas wielder. My plan would be to create a closed system with some sort of radiator picking up the majority of the heat in a closed system. It seems damn complex though; still requiring a water pump - the only advantage is that you don't have to worry about condensation on the processor, as you'd flush out 95% of the o2/h20.

perfume

Hadlock Hadlock writes  |  more than 12 years ago

i think i finally figured out why i'm constanly coughing when i'm @ program six... it's "summer" now, or one might suspect that from what the girls are wearing on the "not freezing" days and the amount of perfume they wear. that might not be a horribly big problem in a school like PSHS, which is designed to move ALOT of air all the time, but at program six, which is designed for about 60 people, tops, and add another 30, then air problems arise. 15 extra girls wearing perfume can make a HUGE difference in the air quality, and the amount of coughing i do in a day. colonge doesn't help much, either. don't get me wrong, you don't see me coughing when i wear colongne, but you'd cough too if you spilt the bottle on yourself.

write a program that takes these sentences and strings them together into a screenplay that is a length between x chars long and x sentences (ap strings?) long....say about the length of a shakespeaian play.
 
output this to a .txt file, and write a program that matches the .txt file up against the original document, saving those documents that match up to 75% or higher. would be interesting to read. sounds like a fun project.... or somthing.

english

Hadlock Hadlock writes  |  more than 12 years ago

Blah. English is an old art form, but doesn't exactly mean it is one that should be learned or practiced for more than 2 years in high school. I'd much rather have an option to take two years of art appreciation instead of my last two years of english. As I understand it, we're learning about t the process of how one reads a book, and then goes out and reads other's views and opinions of that book,, and then eventually decide to write their own review of the book, for others to read. From my (probably) skewed view, reading slashdot isn't too horribly different from this. Someone/some company creates a new techonology or does something extremely creative, that took a lot of combined effort and talent, and shows it off to the world on the internet through pictures and words. On slashdot, this is reported, and many people are allowed to read about this wonderous new techonology or obscure and cheap hobby, then read and write their own reviews (post) about it. It's a community that is constantly feeding itself with new content, providing an outlet for idle thought and time. As with writing, only a small given percentage at any one point is idly working on their "next big project", while fewer are producing a finished product to the community each day. This example is almost mirrored on slashdot, which has a community approaching half a million users (although my guess would be that there are only about 100k active users), where 10 to 12 things per day are posted, and usually about a hundred or so comments are given to each post, while many more people simply read the comments, or "Review/critisisms". There are even two users who regularly do literary things in their comments; one writes haikus, while the other has the user name "grammar nazi". You can guess what he does. I'm already actively parparticipating in a large group that critisizes and compliments eachother's works. Why must another established group's thoughts and beliefs be foreced upon me, especially when I have already been exposed to the culture and clearly don't like it? Taking humanaties 1& 2 in my freshman and sophmore years was far more interesting, and covered far more information of interest. Not suprisingly, english was the least covered in depth. Of course, that's offset by the fact that we already have an ingraied and indeph english progam in most, if not all high school programs around the nation. Still, it's good to not be seeing more literature than I want, and the little you do see, is the eccentric kind and might actually be enjoyed at it's face value, without the complex need to dissect and analyze every small bit. Satire is a favorite of mine: easily recognizable and gets I's point across easily.
