Has anyone done the maths on this (I haven't RTF)..
Assuming this ONLY works on gravity the most force obtained by system is: F = m x a (assume car is 1 ton and acceleration is 9.8) F = 9800 N (say 10 kN)
Work produced by system from car travelling over hump: W = 2 x F x D (assume D = 10 cm, which is a big hump note 2 x force as run over hump twice front and back wheels) W = 2000 J
The power output for that one hour is: P = W / t P = 55.5 W
Assuming we only need 8 hours of light, so we have can say the power supplied is 160 W (Approx 0.2 KW not 10 KW as reported).
Someone can check my reasoning, but 10 KW as stated seems quite high for using gravity of the car.
Point 10).. Just to prove it is not just the XBox 360 with bad PR which sreams "We are clueless and lame", does this marketing really persuade anyone to upgrade to the latest Microsoft office http://www.microsoft.com/office/evolve/default.msp x?
I have flow Lufthansa from England to Germany to Italy several times, and the service was brilliant (plenty of wine, good service and food fine). I haven't flown Lufthansa international, but I would be prepared to bet it is better it is no worse than Northwest (or as we call it Northworst).
I had the unfortunate pleasure to fly Northworst from Amsterdam to India, is has to be one of the most crapiest airlines flights I have ever taken! It was on a old crapy Douglas class plane (one pathetic movie for whole trip, no choice of selecting another movie as it is one big screen for 20 people with the screen out of focus). I only managed to get served one drink from India to Amsterdam (and the same on my return trip). The food served from Nothworst wasn't worth contemplating (cold hotdog, yippeee)
My favorite airlines is Singapore Airlines, United Emerates.
I have two major international trips schedule for this year (one work the other home to catch up with parents), and believe me it won't be Northworst (or KLM for partnering such a crap airline). Might give Malaysian Airlines on my Australian holiday (has been given a few good reports from friends).
>person becomes a good programmer through education and lots of experience. A good programmer can write good code in virtually any language. (Conversely, a weak programmer can write Visual Basic code in any language.) This cry for "keep our precious VB6" sounds suspiciously like the whining "because C is too hard!"
Hmm, I have seen a lot of crap C code (or C++ code for that matter).. I have seen a lot of well structured VB6 programs (just because you don't write well structured VB code, don't expect us to be like you). Problem is a lot of people get paid for programming VB and are self taught, so they don't use all the features (I fall under this category, as University only taught C/C++/Miranda/Prolog/etc). Fortunately over the last three years of work I have learn't a lot of nice programming techniques in VB, so yes I will be sad when it is ended as a product.
> But wanting Visual Basic to last forever simply because they don't want to learn a better language is not going to gain my sympathy.
No, this is not the case for me (as I know C/C++, etc and get paid to write in it). It is the thousands of lines we have invested in VB6, our customers who have written applications using our dlls have invested. I personally prefer VB6 to VB.Net and C# to VB.net. We as a company are looking at still buying VB6 for customers who need to develop code to customise systems we sell, alas they are getting rare as hens teeth.
Bellow link suggests that when the kilogram was devised it was based on 1 litre of Pure water. As a side note, when I bake I simply change ml to grams when weighing water (close enough for cooking).
I want all my music needs sorted, car, plane and home.
When I am in my car I want to use the Head Unit to control my MP3 player, since the iPod is so common several companies such as Alpine and Pioneer supporting with there new Head Units (in Pioneer case you may already have a unit that supports the iPod Adapter).
I just bought a Pioneer DEH 7600 MP (£180) which is iPod Adaptor ready and the iPod Adapter will be available in March with a suggested RRP of US $140 (so with any luck it will be £100 in the UK).
I have been looking into buying an iPod, and have been doing my research, comparing with other products
My requirements are to have my entire music is available wherever I go, when I am in car, when I am in plane at home, etc.
To be at home it must plug into my stereo, which like most MP3 devices is not a problem.
I want a MP3 player to be played for 18 hours on plane, (+ 6 more hours to allow me to get to hotel to charge unit). The iPod can do with the external battery pack, so I will not be limited to the internal 8 hours charge.
When I am in my car I want to use the Head Unit to control my MP3 player, since the iPod is so common several companies such as Alpine and Pioneer supporting it there new Head Units. I just bought a Pioneer DEH 7600 MP which is iPod Adaptor ready.
So I have just bought the Pioneer stereo to replace my old Sony Head Unit (Fortunately I could get my money back under warranty do to faulty CD Changer). I have to wait a few months before the Pioneer iPod adapter is on sale, but after reading the press release I can say I can't wait for it.
For information on a range of Pioneer Head Units that support iPod adapter goto: URL:http://www.pioneerelectronics.com/pna/p ress/re lease/detail/0,,2076_4313_191756410,00.html
I have also looked into Sony's NW-HD3, but the Pioneer iPod adapter sold the idea of buying an iPod (plus with my bad experiences with Sony Support with Vaio Notebook).
I have had several issues with Sony products, such as a Viao Laptop faulty power supply that Sony wouldn't replace under warranty as they believed my system was owned by Dabs (a online computer store in the UK), Car Stereo that the CDs multi stack kept on getting jammed.
But then again you have to take these complaints with a pinch of salt, sometimes some customers (including myself) expect to much.
It is probably a no brainer to guess which MP3 player out I will buy out of the Apple iPod or Sony NW-HD3 player in the next month.. (hint it's not the Sony)
Well if Bill Gates can't get a system to run correctly, I have very little faith in anybody giving support to such a flaky Windows PCs.
The shear complexity of supporting a windows systems, with thousands of drivers written by third party suppliers that have numerous bugs that can produce the all to common Blue Screen of Death. Considering some of these drivers that cause these problems are not installed by the company selling the PC but by the customer installing a new piece of software, the Tech Support is on a hiding to nothing to support any system. Hence we get used to that all too common solution "Please try reinstalling window Sir".
My only wish is when XP detects a critical error that instead of producing a Blue Screen of Death, that it could recover by shutting driver down and not force the user to reboot as the only solution. Considering a lot of Blue Screens appear when system is loading drivers (from my own experience), it shouldn't take rocket science to figure which driver is at fault.
A few years ago I had my heart set on the Toshiba Portege 3110ct, but before I bought the computer I checked to see if linux would run on it (using the linux laptop website).
When I bought the machine I had confidence that it would work. I knew there would be issues with winmodem , but since I had internet connection using 10BaseT I choose to ignore this downfall.
Over the years I have tried several versions of Linux, updating to get a clean install every so often. My lastest install was Mandrake 8.0, this managed to auto detect all hardware (also informing me I should go to a particular website for winmodem drivers).
Moral of story, if there is one. Use the web and goto the linux laptop website, as other people give some accounts in what works or does not work with there notebooks under linux. They will note such issues with soundcard, modems, etc. Note: If they installed on a older version of linux, expect some better support for there unsupported hardware (try searching for web for +linux +part or +linux +notebook, and you will most likely find someone working on finish implementing that part)
Fuel cells are heavy in weight at the moment, and he argues that it is more efficient to burn the hydrogen in a combustion engine (note must be modified to gain extra efficiencies). Unfortunately I can't find to much information on his research, apart from link below
Still part of the problem is storing the hydrogen, as you need very heavy gas containers (heavier than your LPG tanks). But research is being done in storing the hydrogen in a phosphorous material to try and make system lighter and safer.
I am more interested in using Flywheels, as the are making flywheels that can store a crap load of energy per unit weight. You double speed you quadruple energy stored. Also having flywheels that can spin for a year, without being recharged. Also there is some rapid recharge times available for Flywheels. As new stronger materials become available the energy storage per unit weight will increase even more.
The problem with flywheels in car uses is that going over a pot hole could stuff the bearings, but they are overcoming this. The other problem is if the flywheel disintegrates, it could cause some big issues, but using new materials the will give properties that wont lead to total failure.
> I am a collector and can assure you that Lego (Technic in any case)sets have not decreased their pieces on average. Must be looking at the wrong boxes, or different perception when I was young. Last bit of lego I bought would be 15-16 years ago (ouch)..
>You say any kid would go for the PSX over Lego. More to do with price, Playstation was say $1000 when it first started selling it is now $150 (Aus), a big decrease. Lego is over $150 per good kit of technic lego. If your a kid what would you want, 9/10 the kid will choose the Playstation. On the other hand if it was say $60 and the kid had to choose between a Sony Playstation game or technic Lego kit, then maybe the kid will choose the Lego kit.
> And, no, adding more pieces would not necessarily profitable in the long term.
t depends if it will sell a lot more boxes, if a technic lego kit was say $60 (Aus), I would bet you would get a dramatic increase in sales.. Then again I am sure Lego would have done studies on this, so most likely I am wrong.;^)
Well I can remember going into the toy store and looking at the techno lego. When I was young I always wanted Techno Lego for Christmas and my birthday, in those days every boy wanted more Lego.
10 years latter, a lot less hair on my head, my Uni degree in Mechanical Engineering is almost finished, yet I still like looking at the current Lego systems now and then . Over those 10 years the Lego has increased its price dramatically and decreased the number of parts in each kit, so the value of Lego kit was hit two fold.
You can now get a Playstation 1 for the price of a good Lego kit (one more than 10 parts). If you gave your kid a choice these days would they choose a Playstation 1 or a Lego kit, 99.99% sure they will pick the Playstation.
If Lego charged half the price add double the pieces, which would most likely still give them very huge profit margins on each box, people might start seeing some value in it and they might start shipping some of there stock.
If the beer is slightly a different color than is expected you can dismiss the bottle. The train of thought is that if it is a different color there is something different. i.e. unwanted additive or too much or to less of a product, so throw it away.
The theory is you don't have to actually open the bottle to taste test it and it is more reliable to use a machine then a human to spot the difference.
Mandrakes own rpm packer RPMDrake in version 8.0, not because I wanted to but because the command line rpm didn't work, I can say it lacks some good features.
I was installing mandrake 8.0 last night, and managed to stuff up the config file for cups and my simple solution was to reload the rpm.. Or I thought it was, RPMDrake refused to delete the package (hanged big time) and there is no option to install over a corrupt file. The problem with this package was it lacked lots of features that the command line rpm has. So I downloaded the tar file from rpm.org and got a working version.
My experiences with debian (some what limited), is that sure it doesn't have all the nice GUI (or at least when I used it), but it works. I loved how it would automatically download the dependencies, and do a bloody good job.
I do like the mandrake package otherwise, such as there flashy splash screen whilst starting up.
Has anyone run both these packages on Linux to compare, and then compare against MYOB. My guess is MYOB has a lot more features, and is very stable on windows.
I have tried quicken for windows, but unfortunately it was always crashing. I have tried reinstalling windows and quicken, loading the most up to date patches, but to no avail. So we finally migrated to MYOB with no problems).
That's sad. I remember we had an article on shared libraries in linux a couple of days ago, and one of the programs it pointed out was GnuCash. If you do not have the right version libraries it will most likely crash, so before installing please check and see you have the right dependencies.
If it still fails, it would be good to submit some bug reports.. I know its a pain, but since it's a free package think of it as cost to using it. Or if you know a bit of programming do some constructive bug fixes.
I wish all open source packages the best, but I know a lot are still in development so I don't get as annoyed when it doesn't work, unlike when I pay a $100's of dollars for commercial software. I know this is not a good excuse, but I am sure with time GnuCash will be an excellent program. Such as DDD is excellent free debugger, GnuCash is will one day be an excellent account program (*we live in hope*).
Let me ask you why choose MYOB over Excel? Or a word processor over a text editor (vi) for use in writing a CV (I know the real hard core use vi with Latex)..
I haven't used GnuCash but from the little I know it is about managing accounts and finances, might not be at the level of MYOB but it will get there. As the article says it is a accounting package, which Excel is not and does not intend to be. Sure you can do it in Excel but the average joe blow who runs his own business, such as my Dad would not have a foggist in setting up Excel and it is easy to stuff up an account in comparison to an accounts packages.
Well I am a fan of the original, I can remember wasting dollars at the local arcade. Alas I was very pathetic at it, but loved watching other talented and more coordinated people save the princess. Oh those distant memories.
But know there is a new version coming out, and game play is improved (severely limited in previous edition) and it is fully 3D. Goto www.dragonstone.com and check out new 3D Dragon Lair, I know I will use my hard earned cash to purchase it when it comes into my local computer store.
Maximum payload for the Antonov An-225 Mriya is
