This is an old argument that history keeps proving wrong.
Using machines on farms put people out of 16-18/hr/day back breaking work. Oh, no, stop the machines.
The cotton gin will put all the people picking seeds from the cotton out of work. Oh, no, stop the machines.
Using machines in manufacturing will lead to devastatingly low employment. There won't be enough employed people to buy the products. Oh, no, stop the machines.
Visual Basic/Smalltalk/Powerbuilder allows non-programmers to build their own applications. This will put all the programmers out of work.
I use the Code Weaver's Office product with MS Office 2000. Basically it sucks. Even if you ignore UI problems like repainting issues and menus being kind of wacky shifted. Its very unstable. MSWord and Excel crash very very frequently. I find the product is only usable for viewing documents I have received from others and printing. If you are modifying docs then you are playing on borrowed time.
Never tell me that the last thing I need is more choices. I use linux specifically because it give me MORE CHOICES.
ARRRGGG. This is the attitude that has caused there to be a dominant platform. I don't want Linux to be dominant, I don't want Macs to be dominant and I don't want Windows to be dominant. When there is a variety of system, they need to embrace open standards (open source or not), and compete. This can provide better software for all.
Well to be honest, They are also using quite a few years of research, both public (as in individuals) and public (as in government).
Burt Rutan is an exceptionally talented aerospace engineer. However, even he stands upon the research and work of those who came before him. Just as future aerospace engineers will be standing on his shoulders.
Burt is doing some amazing innovations but, he is still using information that cost billions of dollars to discover and research.
Existing stun guns are high-voltage extremely low ampere. High amperes can burn flesh and kill. When the contacts of the stun gun are close enough to flesh, the flesh becaomes the path of least resistence. Thus, the current flows through the flesh. When there is nothing else to conduct the electricity you can see the arc'ing between the contact.
Regarding a ground or using the Earth as a common let me point you here: http://en.wikipedia.org/wiki/Ground_%28elec tricity %29
The shirt should not be tucked in (the under shirt should but, is not visible).
I have never in my life ween a WHITE t-shirt under BDU's.
The "soldier" has a blocked haircut. I've had to do too many push-ups for that one.
Not sure what military he is supposed to be from but, I never saw pants like that when I was in the military.
The "rusty" bit, actually looks like its copper, so it probably should look like that. Although, to your point, I'm surprised its not polished for the photo.
a stun gun (and taser) works by having the electricity pass from one conductor to another, ideally with a body between the two. If you have charged gas, where is your second conductor? I would like to guess that this device would have a wire dragging on the ground to use the ground as the second conductor. If not, then the operator would be the conductor to the ground with pretty hilarious results.
Now if they used lasers to ionize the air (as suggested by the artice), you could have two lasers and use each of the ion channels created by them as the conductors. Admittedly, I have my doubts about this. As, UV lasers powerful enough to ionize a significant amount of air may cause more harm than the electric impulse. Of course, I'm a code monkey not a laser specialist.
To continue your argument, what do compilers have to do with it? Java and C++ and just specifications. Implementation matters. Its the implementation that gets used. My post was in response to the previous poster claiming that the flaw in the test was the choice of compiler. My response was to indicate that the the author of the article chose a mainstream compiler for the Linux platform. I would expect that if he were testing on windows then he would be using VC++.
You are correct, it doesn't mean one is faster than the other. My experience has shown either of these can be faster than the other depending on the application. The which language is faster debate is actually pointless. A language doesn't make an application fast or slow, the developer does.
But, taking your bait... if he uses a better C++ compiler to make the C++ code faster, then the Java camp will say that he should use the IBM compiler and Virtual machine (which is much faster than Sun's). Then if he does that, the C++ folks will say that he should use the Wind River or Intel C++ compiler, then the Java folks will say that he should use the JRocket VM. Haven't we heard Sun claiming since Java 1.0 that it just needs a good compiler and runtime to be faster.
This argument is circular. The point is, he tested both using a common runtime/compiler for each. Most common linux distros have their C++ apps built using g++, this alone means that his choice of compiler was valid. Perhaps he should have mentioned the target platform to really be clear. If he were targeting windows then I would have expected VC++ as that is the most common compiler for that platform.
I started writing assembly in the early eighties as a kid. At the time, it was the right tool for the job. RAM and storage were a premium.
Today, I code in Java and C++. Why, productivity. I've found Java to be one of the most productive languages I've seen (C# may have caught up).
If I were writing code for micro-controllers, then I'd still be writing assembly because it would be appropriate. Writing complex business applications deployed on large clusters of servers would be insane to do in assembly.
To give you credit. I do notice that developers with a strong assembly background write much better Java and C++. Perhaps because they understand what the machine is doing. They know how to use javap to disassemble class files to see what the compiler is creating.
To take credit away. Most projects need the balance of speed and speed of develpment. Usually this is a trade-off between C (speed) to Java (rapid dev). The article suggests that the speed sacrifices are much less than they used to be.
All of our pockets were button up. The only velco in my uniform was on the parachute retention straps for my helmet.
High technology, what? I had to carry around a 40lb picket pounder. tech is a big steel tube with handles on the sides. my other piece of high tech was a mine probe, basically a fibre-glass stick that you poke into the ground looking for mines.
I always thought the high tech stuff was a joke. I only ever saw it on TV. On TV you got guys with portable ground penetrating radar looking for mines from a distance. In the field, you have a guy crawling on his belly poking a stick in the ground.
There was actually research done during the devlopment of the stealth bomber about how to make it less noticable to the naked eye. The reseachers found that by painting the bottom pink (surprisingly not blue) that the planes were practically invisible from the ground (day or night).
You can imagine why this never made it past the research phase (insert joke here).
The other reason is because projection increases the amount of light on the scene.
This isn't a big deal against the naked eye which adjusts. However, when using light amplification devices (aka night vision) any extra light will stand out quite a bit.
They do it by downloading the movie to your harddrive. So, throughput is less of an issue.
You can download the movie while you are sleeping and watch it later. Or, you can start the download while you make popcorn, effectively buffering that time. Then start watching when you are ready. Pause the video to go to the bathroom, increase the buffer. Rewind a portion of the video, increase the buffer. Its actually pretty decent for video on your computer.
Comparing with Netflix. Well, you also have to wait for the video to show up in the mail.
Of course, I'm a bit different than most because I have a dual-head matrox card with the 2nd head doing TV out to my video switcher. So, I do get to watch it on the TV. My reason for this is for web/email access on the couch with a wireless keyboard mouse.
This service actually has you download the movie to your hard drive. So, there is not streaming video in this case. If you are *buffering* then you are buffering from your hard drive.
Since it is protected with DRM, it would not be much use to burn it onto a cd or dvd.
purists, please note: in this post "Linux Distribution" is shortend ti "linux".
It also make me think of the Walmart.com offering Lindows/SunJDS systems. At first I thought this would be bad for linux. As clueless (not meant as an insult) users would be lost using it. Then I thought, most of these customers probably only want to surf the web and read email. They don't know about firewalls and anti-virus programs and all the other things they need to protect themselves. So, maybe its better that they start off with a system that is mostly secure by default.
Granted they can't play many games but, almost all linux distros come with the most popular and most used PC game of all time, Solataire. Anyway, my grandmother isn't looking to play the latest FPS. She doesn't even know what the diff is between linux,mac, or windows. I switched her from WinXP after several virii thrashed her system to Mandrake (minus all the excess apps) and she is very content. She likes being able to check the whether in evolution. She like that Mozilla crashes very rarely. She likes that she no longer has *operating system rot* (google that one).
Basically, she doesn't care about Linux vs. Windows. She doesn't care about IE vs Netscape/Mozilla. She wants to check her stocks online, she wants to read news, she wants to read her email and see pictures of her great-grandchildren.
So, I'd say linux is appropriate for the casual computer user or the experienced. Those in between may not want to deal with things like driver support and config. The casual user doesn't change hardware so, drivers aren't an issue. They also, rarely change any config from default. They also, almost never install their own OS (a system without OS rot means they don't have to re-install periodically.). The experienced want power.

And if you had actually tried the Helix (or RealPlayer10 for that matter) for Linux you would see that your statement is just plain out of line.

Then just add a composting tank to the sheeps belly. :)

I'm still waiting for a review of someone who's actually used one of these.
So, what linux software do we have that will take advantage of this? Are there Mesa or Glide extensions?
I'd love to try one of these but, if none of my apps use it then whats the point?

Actually, you can conclude that the JVM's are getting better since previous ones were slower than g++.
To make a conclusion about the quality of g++ we would need a comparison of g++ vs other C++ compilers, not against Java.
To continue your argument, what do compilers have to do with it?
Java and C++ and just specifications.
Implementation matters. Its the implementation that gets used.

There are lies, damn lies, and benchmarks.
Suprised because he used the compile that ships with most linux distros?
