> I'm curious what practical applications there are

None. It's totally pointless actually.

Very cool, but pointless.

All those solar cells and batteries cost more than just fueling it with regular fuel, and leaving the solar cells on the ground to power other things.

> Cheap, quick-to-setup communications relay
> Small datacenter
> Long-term airborne

Not cheap at all, and a blimp (zeppelin) would do a much better job for all of those.

(The batteries alone cost more than $20,000, and the solar cells probably in the $100,000 range, and the carbon fiber around $50,000 for the raw materials. I would estimate half a million each if mass produced.)

It might possibly be interesting for continuous surveillance, if you have no ground station where you can land. (But it flies so slow (43 mph) that it would take a very very long time to get anywhere.)

For regular constant surveying it's cheaper to have two planes and use them in relays.

I'm all for reducing hydrocarbon usage, but lets reduce it for fixed installations, and save the hydrocarbons for the mobile ones (planes, cars).

If you look at the specs http://en.wikipedia.org/wiki/HB-SIA it can just barely fly, it's not even strong enough to hold two people.
As someone who just managed that this year, a few pointers.

1. Budget.
I know it sucks, and I know it is a hassle, still, no way around it. Grab excel or numbers or openOffice and do it start of each month.

2. Split accounts
I have used this technique to great success.
- 1st account is the "INCOMING" account, This is where all incoming money goes to and all fixed costs (see 1. Budget) go away from.
- 2nd account is a "pocket money" account. Pocket money is transferred there. Nice about this: You can spend ALL of this and your bills and food are still paid.
- 3rd account is a savings account. Not much to explain here. Make sure to save a good amount.

3. Keep at it

4. Get a seperate wallet for "food and household". I usually get a laugh about this, as it was something our parents used to do. Still, I withdraw cash beginning of the month and pay my groceries from this. Works wonders.

5. Keep at it

6. Use a big chunk from your savings account to remove all remaining debt at once.

7. Enjoy freedom.

I know people will go on about "credit history", "credit rating", etc... However, I plan to nev er go there again.

Best,

Same here. I save it on my dropbox account, just in case I needed access to my password when I am away from my computer.
I have to say, I am not impressed with the article... "Perpetual Flight?" I say yes you can probably fly this airplane forever until a motor breaks or something BUT there is a big difference between a single pilot airplane that takes a team of people to ensure it does not have the wings scratched and a commercial airliner that runs on solar. While the airliner is awesome if we can pull it off, I would not be surprised if we were 20-50 years away from that.
I went into this with the same assumption and was disappointed to find out how wrong I was. There are two separate systems in play: PMS (property management system) and lock management. A PMS may provide everything from online booking to PBX management. In larger properties, these systems will be connected ("interfaced" in hotel lingo), but it's rare to see this in a small property; it's insanely expensive as it stands.

So where we stand right now is that if you're already interfaced with PMS, our system drops in and works with it no problem, but it's still expensive to get such a setup. We're working on our own PMS API which will allow much simpler, direct communication with our system; we hope we can drastically reduce the cost by doing so, as the current state of affairs is poor.
I would like to get my black belt in Taekwondo by the age of 30 (turning 23 in August) and fight at a Canadian national or Ontario provincial competition. I am currently a yellow belt (started about a year ago) but have won a gold and a silver at two recent invitational competitions.

I had an excellent teacher in Thunder Bay, but just moved to Toronto a month ago to be in a more tech savvy town (I'm a developer) and am having difficulty finding a dojang that I like and that gives attention to nurturing their lower color belts.
Background: I'm a .NET developer in a Windows shop by day, and run OSX on most of my computers at home (except my primary desktop which is Win7 for gaming and .NET development).

My major pain points on Windows that lag behind Linux/OSX:

- Scripting. PowerShell is getting there, and is fine for system related tasks, but it remains a second-class citizen.

- Application Installation. No apt-get; no simple dragging an app into the Apps folder. Same for uninstallation.

- Security. I don't hate UAC nearly as much as everyone else seems to, but give me sudo any day. I'm also concerned by reports I've read of how easy it is for malicious software to get around UAC.

- Settings/Configuration. Control Panel is still a cluster fuck and every app on my computer seems to have a different route to their custom config screen.

- Startup. Yes I know about msconfig, but my wife certainly doesn't, nor does my mother.

I don't hate Windows. I make my livelihood from it, use it all day with little complaint (Win7 is my favorite Windows version since Win2000), and its clearly the only real choice for PC gaming (I have like 3 games for my Macs via Steam). That doesn't mean I am or should be blind to where it falls behind its competitors.

For what its worth, I have the same feeling about .NET: I use it, love it, make money off it, have fun with it; but I'm not blind to its faults.
Reference for outsiders: my only substantial argument so far is the quote in this comment: http://news.ycombinator.com/item?id=1497246
At least that is specific. I've also used several pieces of (European) software which forbid themselves from being used for the creation of nuclear weapons.
Interesting, but not very convincing. The argument concerns historical periods when the costs of research were not nearly as high as they are now. As your own source rightly points out:

"the total cost of bringing a new drug to market [is] around $800 million, in year 2000 dollars... [T]his figure suggests a spectacular increase in the cost of innovating. This increase is due, mostly, to the capitalization of the longer and more expensive clinical trials the FDA requires."

It may well be that patents were not always necessary for drug development. It is lazy thinking to conclude from this that they are not necessary now.

Yeah, but all the evidence pursued from a false basis can be thrown out of court. I remember a landmark case sometime ago where cops imaged a house using infrared, and those images, purportedly showing a pot grow house, were the basis for a subsequent entry warrant. However, the court (may have gone all the way up to the Supreme Court) found that the initial infrared imaging was invasive, infringing and illegal, and thus all evidence coming from it was tainted and had to be thrown out. Therefore, it seems to me that a single weak link in the chain will nullify all the next links.

IANAL.

I visited Vietnam three times over a 3 year period. Is it your first time?

Since my last visit, laws have changed that require you to wear a helmet while on a moped. One of the things I enjoyed the most was the freedom in riding a moped around a huge crowded city for hours, not knowing where I was going, or where I'd end up. It's somewhat ruined now with the helmet law. Nearly 100 degree weather wearing a helmet isn't so fun.

The whole idea of going from canned set routines to dancing to the music is a bit of difficult hack that I'm still working on (but making progress). The hack for that I think is understand the structure of the song - (real-time Fourier analysis of a set of eight measures of 8-beats each..with your feet)

The difference being that judges are entirely happy to make precedent-setting rulings on what "use, copy, modify" et cetera mean. I don't think any judge would be willing to rule on whether a particular use of the software counts as "evil".

Even if they're presented with a case where someone is using the software in an unambiguously evil way (like, I dunno, kidnapping small children to use as sex slaves) then they probably still won't rule on that, because that creates a precedent that a judge can rule on whether something is good or evil, creating difficult situations for future judges.
Yes please compare apples to apples. Claiming that iPhone did not support something for only a year is BS because thats how it launched. what about multi-tasking? Oh iPhone didn't support that for a couple of years only.

GRANTED that iPhone is first-to-market and actually created the market, so they get the brownie points because there was nothing even close available. Now if you want to compete with the iPhone to any extent you MUST compete with the iPhone of today, not the iPhone of 1G.

You will probably want to start with CS concepts, given that from what I have seen NLP is a very algorithmic area of research, having some CS/math background will help you a lot to understand what has already been done and to build on it.

Now I'm not sure the best way to go about this, either learn the abstract concepts which might not be the best way to start or pickup one of the more pure languages which in turn will teach you concepts when you learn how they are implemented in the language.

You wouldn't want to use it for any of that - a balloon would be better for the two first, since you want it stay stationary over the area that you want to cover, for the second you also want a balloon as you again want it stay stationary over the target.

The third point doesn't get you anything, the middle of the Atlantic is technically not part of any duristriction, but the plane it self would fall under the duristriction of whatever countrys flag it flew.

As for the last point, a Zeppelin would be better and it would be trivial to power that by batteries (or even just solar cells and simply let it turn of the engines at night or when there is really bad weather).

one 400W bulb isn't sufficient, as far as I know (I have also never grown, but have known people that have) From what I hear, one bulb MAY get you ONE plant harvest (2-3 ounces) every 3 months, IF you do it all right. My understanding was you need 3-4 lights. There's no way you're growing 5 plants from 1 400 watt bulb.

>$20/mo for the electric for the lights

this doesn't seem right, let's do 500 watts for simplicity (watering system etc needs more power)
So, 0.5 kwh 18 hours a day, so 270 kwh per month so you're starting at like... $40-$70/light.

so maybe $400 + $70/mo per plant, 3-4 harvests a year depending on how often you fuck up, that's like 300-400 a plant or about 100-150 an ounce, same as know-a-guy prices outside of cali...................

>Never had to purchase drugs, but lets say the seeds of the strain you want cost $250.

They're way cheaper than that, but you also need mylar lining, watering system, etc.

I'm training for the 'Yorkshireman Marathon' in September in the UK. Its 26.6 miles of hilly off road tracks with over 3000ft of ascent. I don't just want to finish it, I want to get in between 3.30 and 4 hours.

The biggest problem at the moment is finding the time to train. Ideally I would like to be out everyday but I can only manage 4 days a week. Each training run is lasting upto 2.5 hours and finding that time each day is tough.

The rest is fun and massively rewarding. As I get fitter I need less sleep and I feel much stronger - both physically and mentally.

Correct. We may want to test for that, if at all possible. Also, if we manage to reduce the costs of clinical trials, we may make that point moot. But in the end, I fear we will have to set priorities, and make compromises. I just hope that it will be based on rational judgements, instead of political stances alone.
