NASA Chief Tells the Critics of Exploration Plan: "Get Over It"

Hadlock Re:It doesn't take much (196 comments)

The commercial crew program does this in a realistic way. For about $2 billion we ended up with the Dragon, the Dream Chaser and whatever cargo lump that Orbital built, plus Orion. Three out of four are designed to be human rated.
 
Blue Origin got some first and second round funding but they're way behind the curve compared to everyone else. Even Dream Chaser put down money for an Atlas V for a test launch already. Bigelow already has a "space station" in a near-polar orbit since 2006, but nobody's visited it yet.

Will the Nissan Leaf Take On the Tesla Model S At Half the Price?

Hadlock Re:Oh noes, I can't drive X miles (389 comments)

If it's your only car and you can't drive round trip to the largest near by city (Dallas-> Fort Worth and back ) on a single charge (can't always find a charging station in a strange town) it's not much good. Sure you can rent a gas car for long weekend trips, but that's really inconvenient for emergency trips or if you want to go see a concert, art festival, state fair etc one county over.
 
Right now it's just a supplemental car. If I could get 200 miles out of it, I could drive to Austin on Friday after work.

SpaceX Launches Load to ISS, Successfully Tests Falcon 9 Over Water

Hadlock Re:Not sure about the recovery test (125 comments)

The weight of the fuel decreases as you burn it out the back of the rocket, increasing efficiency For each second of the burn. Second, did you account for the rotation of the earth underneath the rocket? Zeroing out the forward momentum does eat up most of the fuel, but you don't need a whole lot of forward velocity to fall down a parabolic arc from that height to return home. Landing requires about 60m/s of delta v at it's new mass.

SpaceX Launches Load to ISS, Successfully Tests Falcon 9 Over Water

Hadlock Re:Not sure about the recovery test (125 comments)

The rocket (1st stage) when empty needs almost no fuel (about 4% of the total fuel at launch) to return to the launch site and land. The upgraded Falcon v1.1 has 10% more fuel at launch as well as increased cargo capacity (more efficient engines). Hitting a floating barge means you have to have good conditions at the launch site, as well as 400 miles out at sea as well. That dramatically limits your launch capability and exponentially increases your recovery costs.

How Apple's CarPlay Could Shore Up the Car Stereo Industry

Hadlock Re:Why spend another $700 for a car stereo (194 comments)

That's pretty much the exact opposite experience I've had. I've never had an issue with BT audio, even once. Range seems to top out at about 30 ft and for music listening, is perfect. I've run in to audio lag (20-40ms) issues when streaming audio to bottom tier $20 adapters but it's completely replaced physical audio cables in my house. The sounds system in the living room and bedroom both use it exclusively and I just stream to either/or from my phone as the "head unit" and use the speaker system as a dumb Amp.

Ask Slashdot: Are You Apocalypse-Useful?

Hadlock Re:The magical scenario is "gradual social decay." (737 comments)

You could rev up to about 1940's era technology pretty quickly. With the exception of flat screen TVs, the internet and integrated circuits that brings us pretty close to modern standards of living. After that you've exhausted all of the low hanging fruit like high tensile steel, most ceramics and crude plastics. Space age technologies (flexible products like modern rubber, silicone rubbers and other elastomers, hyper pure titanium, rare earth alloys, etc and of course Velcro) took about 4% of the national GDP to identify uses for, and then produce on an industrial scale over the period of a decade. This was on top of an incredibly prosperous era and winding down from the education boom of the 1940's that produced the scientists needed for the space race. Given any other outcome, we'd be lucky to have late 1980's technology today.

How the Internet Is Taking Away America's Religion

Hadlock Re:trees have branches (1037 comments)

There have been quite a few studies on how single-digit percent of Jews actively practice religion and/or marry a religious Jew; however those who observe at least some traditions from a cultural standpoint is well over 75%. We're all creatures of habit, but somewhere along the way we mixed religion and custom together.

Slashdot Asks: Will You Need the Windows XP Black Market?

Hadlock Re:How much does it cost to upgrade? (245 comments)

People were still implementing new, paper-based workflows in 2000. By 2004-2005 that had mostly gone away, but jumping from NT4 to 2000 meant jumping 25-40% of the office to a new version, typically the smarter and higher earners who deal with change fairly well.
 
By 2005-2006 you're looking at Vista era and half a decade of XP dominance, nowadays all employees not working in food service and/or retail are assigned a desktop. This resulted in a huge upswing of PC sales which has now leveled off. So now in addition to server class hardware and A-level users, you're also having to migrate your B, and in most cases C, D, and E-level users at the same time. Even the guy in the mail room needs a PC to check email from his boss and HR once a day. Our copy room has a desktop to open word files.

Classified X-37B Space Plane Breaks Space Longevity Record

Hadlock Re:Wait a moment (123 comments)

I'd like to see Voyager handle reentry through Earth's thick atmosphere and land gracefully on a runway. THAT would be a sight to see. Voyager 2 technically survived going through the rings of Saturn, but even that managed to take out several instruments (even though, to save someone's career that's not the official reason why they mysteriously failed immediately after)

Tesla Model S Gets Titanium Underbody Shield, Aluminum Deflector Plates

Hadlock Re:Very amusing but... (314 comments)

My 1997 BMW 5 series (the Tesla competes with the 2014 7 Series) has a thick plastic underbody shield. It was designed in ~1992 and started production in Europe around 1994. So it's not a new concept. It also still gets 33mpg @ 70mph on the highway from Dallas to Houston and isn't a diesel.

stillborn

Hadlock Hadlock writes  |  more than 7 years ago

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.

infinite number of monkies and a FINITE amount of time...

Hadlock Hadlock writes  |  more than 12 years ago

if you wrote a program that would grab all the words of a specific text into a wordbank database, and then randomly string them together in random sentences, adding punctuation with primitive grammar algorithms.
 
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.
