Russia May Be Planning National Space Station To Replace ISS

Hadlock Re:What do you mean "may be"? (225 comments)

That was true in 2004, however with redundant systems installed since then, the US portion is capable of running on it's own today.

Russia May Be Planning National Space Station To Replace ISS

Hadlock Re:What would happen? (225 comments)

It was designed with a 10 year service life, then re-rated for 20 years. Current plan is 2024 but after that is really stretching things and major modules need to be replaced due to stressed placed on them by boosting the orbit (the ISS is actually in the upper atmosphere and loses about 2km (1 mile) altitude per month due to atmospheric drag. It gets reboosted by Soyuz and Progress spacecraft periodically.
 
Yes you could keep it going indefintiely but eventually the safety factor drops below an acceptable point. Based on what's there right now, that safe point is 2024-2030.
 
A next generation space station could possibly exceed a 25 year design life, but really, 25 years is pretty damn good given this was the first try since Space Lab for the US. For the Russians this is old hat, their segment(s) are just repurposed MIR 2 parts.

Russia May Be Planning National Space Station To Replace ISS

Hadlock Re:Why such a short lifetime ? (225 comments)

It's not like we had hundreds of years of heritage in designing these things. We have yet to have a satellite collide with a human-populated space station. I'm sure we'll learn a lot about what to do/not not do with space stations in the years after that first event. Designing a space station module to survive multiple tens of thousands of MPH impacts with space debris, satellites, micrometeorites, etc for not just 10 years but 100 years is asking a bit much, don't you think?
 
We've only been building "semi-permanent" space station modules for 10-15 years. It's not like you can just ship 3 tons of bricks, some cement, mortar and trowels and tell the astronauts to build something "roughly airtight and space station-y looking" and hope for the best for 100+ years.

Russia May Be Planning National Space Station To Replace ISS

Hadlock What do you mean "may be"? (225 comments)

Russia announced that they were planning to end their involvement with the ISS in 2009 or so. This is nothing new. They've been telegraphing their displeasure with the ISS program for half a decade or more, and their lack of willingness to continue with it past 2020. The portions they're sending up to the ISS will be detached and converted in to a separate space station shortly after 2020. This is not "news", this is "established fact". Maybe it's more noteworthy the second time that they publish this through official channels?
 
The ISS will be a 20 year old international experiment at that point, yes the US and Russian halves of the ISS share a common "atmosphere" but mechanically they're completely separate space stations capable of detaching at any time. Most of the Russian segment of the ISS is made from leftovers from their MIR 2 project. It's no surprise that they're wanting to separate from the ISS. Those space station modules have a finite lifespan and most of them will be nearing their operational limits around 2020, with a maximum lifespan of 2030. Either we replace them with new modules or deorbit the whole thing. Russia has decided to replace them with new modules and go their own separate way. They've been talking about this for a looong time. The ESA has been talking about teaming up with the Russians moving forward, rather than NASA on the next space station. China ended up building their own space station after being turned down by the Americans. We're not making a whole lot of friends in the aerospace field with the ISS these days. The New ISS may be everyone - (minus) America next time around, due to our overwhelming fear of sharing orbital technology with the Chinese (who aren't allowed inside NASA buildings, just ask any Chinese aerospace engineer).

What Would Have Happened If Philae Were Nuclear Powered?

Hadlock May 2015 (493 comments)

Due to several sources closely linked with the Rosetta program, Philae will be getting a whole lot of sun come May 2015 due to the position of the comet as it adjusts it's precession around the sun and moves that particular part of the comet in to near-constant daylight. Expect more news at that point from Philae. You heard it here first, folks.

Lunar Mission One Proposes To Take Core Sample, Plant Time Capsule On the Moon

Hadlock 20M drilling project on very fist lunar mission (69 comments)

Did these guys just say "hey let's do a lunar sample return mission! high five!" and throw together a kick starter? They don't even have a target launch vehicle chosen yet. Not only do they want to do a return sample mission (something China has been working on for 15 years) but they want to drill a 60 ft hole in the moon while they're at it. This is, to use a pun, lunacy. The logistics involved of entering lunar orbit, let alone landing are incredible. And they want to throw a 60' drilling apparatus on there that will work flawlessly? Not even the ESA can get their 8" drill to work on the comet correctly and that's just ice.
 
Good luck with that.

Rooftop Solar Could Reach Price Parity In the US By 2016

Yeah but now that it's in place how many trucks are up there? Other than periodic maintenance, how many 18 wheelers service that farm in a given year? Three? Plus now you have a bunch of awesome ridge top mountain biking trails, improved access to the wilderness etc etc. Other than the short term inconvenience of a major infrastructure project going in (oh no!) your long term view of the even longer term benefits of the site seem awfully jaded given the extremely low impact (i.e. none) to your daily life.

Toyota Names Upcoming Hydrogen Fuel Cell Car

Hadlock Re:How do I refill it? (194 comments)

Probably contract with Tesla to put a hydrogen station next door to their electric station, since there's already an all-electric network from coast to coast. The "green infrastructure" is already there, now Toyota can leverage off of that

How To Anesthetize an Octopus

Hadlock Re:How?? (105 comments)

Octopus are basically water going aliens that crash landed on earth, they have separate brains for each eyeball and almost as many neurons in the tentacles as the brain, plus their motor cortex is doughnut-shaped and encircles their throat. Yet they're smart enough to unscrew the lid of a peanut butter jar if they're trapped inside one, and more often than not can pick the winner in a soccer match. The fact that we have any idea of how to do anything with something as weird as an octopus is pretty damn impressive. This is hard core nerd biology/medicine, cutting edge right here.
 
Look, just be glad they didn't post pictures of ktitens, ok?

Will Lyft and Uber's Shared-Ride Service Hurt Public Transit?

Hadlock Re:I use Uber over public transit (237 comments)

There was a HUGE pushback against the Dallas DART light rail in the mid-90's when it was announced, however initial turnout was 50% higher than even the best expectations and they accelerated plans for the subway portion through uptown to the suburbs. Nowadays there's 4 or 5 lines, one even connects with the major international DFW airport. The station by my office has a train leaving every 1-2 minutes during peak rush hour, completely packed for the suburbs. I am the only person in my office that doesn't take the train (because I bicycle in).
 
People fucking hate riding the bus, but they love the train, for whatever reason. Maybe because they're bigger inside and you can walk around. And the route/stops never change. Now DFW boasts 96+ miles of commuter focused light rail, with another 20+ miles coming over the next decade (compare to 650 miles for NYC). That does take quite a few cars off the road. I would guesstimate our office takes about 800 cars off the road every day using rail.

Will Lyft and Uber's Shared-Ride Service Hurt Public Transit?

Hadlock I use Uber over public transit (237 comments)

Parked my car a year ago and I ride my bike to work most days. There's a bus stop less than 200 feet from my house. If it rains or gets below 40F (it's Texas, only gets that cold maybe 3 weeks a year) I take an Uber. Since I live 3.2 miles from downtown it costs between $6.43 and as much as $8. A single bus ticket costs $2.50, drops me off six blocks from my office, and runs on their schedule, and is frequently late. For $3 more I get dropped off in front of my office, they pick me up on my schedule, I get a real seat belt, appropriate heating/A/C, listen to NPR, nobody asking for money or sitting next to someone not having showered for a week etc etc. I usually take the bus home for $2.50 as I have more time in the afternoons to wait for a bus.
 
Parking downtown costs $5 for the bad lot four blocks from my office, $7 for a semi private parking garage. That's $100-$150/mo to rent an 8x10' piece of ground.
 
There's a very slight premium for using uber, but compared to paying for car insurance, maintenance, gas + the hassle of driving myself around, Uber is a fucking deal. In my very very corner case. That $1.50 a day premium is a really nice premium that really improves my morning, for those days that I need a car to get to work.

Comet Probe Philae Unanchored But Stable — And Sending Back Images

Hadlock Re:Couldn't they have used an RTG? (132 comments)

France operates a number of breeder reactors that could be repurposed possibly. Since the Regan administration (in fact, Regan himself) we've lost the capability to manufacture Plutonium in abundance. Not that there's a lot of use for the stuff but the supply is running low as is it's half life.

Amazon's Echo Chamber

Hadlock Re:Uh (112 comments)

Re: Cable Cutting
 
The Amazon FireTV (the full size square, not the HDMI dongle) is a fantastic device for $99 and XBMC has native support for it now. Once you bump the buffer from 20MB to 500MB and remove the bandwidth cap XBMC + Amazon Fire TV is a fantastic device for streaming the largest uncompressed 1080p video. It also handles your standard 100MB-4GB video files without cache modification as well. Also it does stuff like Netflix, Amazon Prime (aka HBO), most Android apps (like BombSquad, a Smash Brothers clone), you can side-load APKs without rooting it etc etc Amazon did a great job with the device and I use it daily instead of owning a cable box.
 
Absolutely zero interest in an Amazon branded phone though. I heard their Fire Tablet or whatever was pretty fantastic for the time but the market has moved on and even the $79 chinese branded tablets are competitive these days for most users.

Elon Musk's Next Mission: Internet Satellites

Hadlock Re:Another Teledesic? (74 comments)

Of note, high efficiency station-keeping engine technology has exploded in recent years, there's at least six cubesat kickstarter projects, mostly in the 2U-3U size which can at least partially get out of LEO on just a tiny, tiny amount of "fuel". Ion/electron propulsion has made huge advances in the last 15 years and is expected to bring the cost and size of communications satellites way, way down.
 
Right now fuel + engines + station keeping makes up 50% or more of a communication's launch mass. With electric propulsion, station keeping will make up less than 10% of the satellite, which in turn means less fuel required to push that mass around.

The Effect of Programming Language On Software Quality

Hadlock Burn PHP (217 comments)

Not sure if it's the fact that you can host PHP on Godaddy's lowest tier(s) or what, but PHP seems to be the lowest hanging fruit and a lot of "babby's first project"s are written in PHP. I know a few people who avoid PHP projects based on that principle. The average PHP project seems to be dramatically lower in quality compared to similar ones written in Python, Ruby, heck even C#/ASP.

New Atomic Clock Reaches the Boundaries of Timekeeping

As of about 2010 we already had clocks so accurate you could demonstrate relativistic effects by separating them by just a few feet. It sounds like the vibration from walking in the same room as these is enough to knock them out of sync.

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.

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.
