A team of nine women will deliver a baby in one month. Through four iterations per week. In each iterator one body part will be produced and delivered.
The problem is, most people whose idea of complex software is address parsing for Latin American addresses and they think something that worked there will also work for hypersonic combustion simulation. Agile may be good for this kind of data warehousing, porting, merging products, GUI development etc. But there are software where Agile is not suitable. But very hard to convince the Agile fanbois to agree on principle in theory there could be software projects where Agile methods do not work.
1. There are already products that are shipping. They were developed sold and they have to be maintained. No point in saying it should never happen in true agile environment. Agile has to take existing code base and existing programmers and hit the ground running.
2. These developers are expensive. Many companies cant afford to hire the second turbulence modeling guy or the second boundary layer meshing gal or the second transonic flow specialist.
3. You can't reimplement or refactor their code. They are often hire for their math and physics skills and their programming skills are atrocious.
1. It definitely tells the management what they want to hear. Timely delivery, early notification of slippage etc.
2. It at least notionally asks the management to consider resources while committing to features.
3. It allows some kinds of software project to managed better. Things like merging products when companies merge, or when porting software to a new platform etc.
4. It works when the project has a large number of people with identical or largely similar skill sets. If the project has large number of specialists (like "Frank here is the only one who can even touch the turbulence modeling code") development will be slow, agile or not. At least the management should know not to commit to too many turbulence modeling features.
5. Rally proponents broad brush all skeptics as "people not willing to change".
6 Too many Rally concepts come from manufacturing and some of the examples and analogies don't even translate correctly. Take the famous, "burnt toast" example. A company decides to burn all the slices, and then scrape off the charred crumbs to get the color desired by each customer. Supposedly Rally will toast them right in the first try saving all the efforts that go into scraping off charred crumbs. Well, in software it does not cost me any money to char a toast and scrape the crumbs. Often times it is perfectly ok to render all the pixels of each body, even if another body is going to come back and override a lot or most the pixel later. You waste time trying to predict the final pixel value to render it just once.
7 Some times it is funny to see the Rally proponents not using Rally methods to develop their presentations, not using Rally for their own internal websites! Too many of them recite from a text book or a holy book instead of using actual code/project examples.
Yup, anyone who is insane enough to promote fairtax.org should not vote. But they seem to be the most ardent types who end up voting. These people are the unwitting tools of multinational corporations and rich people but dont have the brains to realize it. And they get all worked up and angry and vote against their own best interests.
This is two stroke diesel engine. All diesels are fuel injected. Though diesels do have better torque at low rpms, even they can't match the electric motor when it comes to torque at zero rpm. Electric motors have peak torque at 0 rpm, exactly what you need to get the vehicle in motion. That is why even diesel locomotives run a generator and use electric motors to haul a train. It is not enough to beat the electrics in efficiency, you need to beat it in torque too.
The only reason IC engines are even competitive with the electric motor is because of the high energy density of the fuel carried on board. If you solve the energy storage problem for the electric motor, there is no way IC engines could compete. Not on efficiency, not on torque, not on emissions, not on noise pollution, nothing. You are held hostage by the fuel tank. Not the IC engine.
What was the damn case about? I understand all the words written there, and get the snarky tone of judges at the beginning, but cant make head or tail about the actual dispute was about.
That girl, who is she, Jenny McCarthy or Jen Aniston or whoever, will protest that these immunizations create autism in mosquitoes and the idiotic press will cover it wall to wall and the mosquitoes will get scared and none of them will show up to take the immunization shots.
Lets say there are billions of inhabited planets. Then they should be popping into a passing black hole or be blown away for an intergalactic highway project now and then. But I have never felt a disturbance as though millions of voices suddenly cried out in terror and were suddenly silenced. How come?
This is what happens when you don't have a life and play games all day. You reach a point where you complete all the games on the day of purchase and you are left despondently looking at the basement floor and begging mom for more money to buy more games.
On the arms production side, USA was able to convert so many auto factories into tank factories and airplane factories. Allies had breakthroughs in cryptography. The Generals were at least listening to the statisticians. Or at least the quants were able to get their idea up the chain of command. And people bought war bonds and planted victory gardens.
Now we are fighting two wars (Afghanistan and Pakistan). Even that is proving to be a handful. Can USA stand up to a mighty enemy likes of WW II Germany or Japan?
In a recent press release The Fine Printers Assosiation of America announced that it has been much maligned by the popular press. Mr Ucant R Eadme, their spokesman said, "Our members, mostly lawyers, food ingredient label designers and medical commercial copy writers have been engaged in a long standing and diligent effort to improve the reading comprehension of Americans. But they have been systematically mischaracterized by the popular media as selfish people helping malefactors to bury incovenient gotchas. Now that scientific research is showing that our activities are improving the reading skills of Americans, we are planning to claim it charitable in-kind donation. We expect to cut our onerous tax burden by several billion dollars."
You are correct, the train does not have to be infinitely long. My original draft had an infinite frictionless wall that is slipping by and that starts to grab you once you curve it. Changed it to a train to make it more imaginable. Sloppy proof reading left the infinite part in.
Let us say you are hanging outside by holding on the window bars a long train (make it infinitely long train, who cares? it is theoretical physics, Also make it a train in India because most trains in Europe and USA have glass windows with no grab holds) and the train is moving with some speed. The outer walls of the train would not grab you and hold you against gravity. You have to hang on with your dear life. But if you curve the train track to make it circular, you will experience a centrifugal force that pins you to the outer wall of the train, and you can even let go of the window bars and shout, "Look! Ma! No hands".
Of course you know that centrifugal force is not a real force, but a pseudo force you conjure up if you are working on a reference frame attached to the train. From an inertial frame of reference, your velocity is being changed constantly. Change in velocity is acceleration. The change in direction would be towards the center of the circular track. That acceleration is centripetal acceleration. The train is exerting a force centripetal force on you. The reaction from your body on to the train for that force times friction coefficient gives you the force that is holding you still stuck like a fly on the wall of a train moving in a circular track.
As one who has spent years hanging on to the window bars of trains and buses in Chennai, India, let me tell you, no matter how many Einsteins tell you that is a
pseudo force, it felt real and that I am still living, not having been run over decades ago by the next bus or train proves that centrifugal force is real. Not pseudo.
Similarly the fermions seem to be having a mass to satisfy some equation in some frame of reference after some coordinate transformation. But really it is not creating any mass.
I am very sure the X10 camera people (and their customers) are going to be more interested in this than the military. I wonder if the stupid pop-ups and pop-unders by them were the final straw that pushed users to start seeking for alternatives to IE and FireFox (or FireBird or Phoenix or whatever it was called back then) was at the right place at the right time.
Every decade they find some keyword and the slap it on everything in sight. In the past they have indiscriminately slapped "motor" "radio" "jet" "aero" "bio" "e-"... Now it is "nano".
Gimme a break. These batteries are based on electro-chemistry. You know, interactions between molecules. Everything that goes on in batteries, all batteries, are nanoscale, by definition. Corrosion in the electrodes had been known and studied for ages. It is a damn chemical reaction that will happen at molecular level.
A professor stores 10 years of his work in a single laptop without any back up? I just lost all hope for humanity. If that prof is from the School of Liberal Arts, I lost all hope for humanities too;-)
Not always. In some univs with direct admission to PhD from BS they might have structured the program that way. But not always. One can register for and pursue an MS alone and then decide to go for a PhD at a later date.

meaning those who chose not to vote had a real effect: they helped bush win
Nope. Bush won by just one, repeat just one, vote. 5 to 4.

Thanks. Wish you are a judge or judges write as lucidly.

The cure is simple, get a life.

If I followed your advice, I would have forgotten you and your posting here at /. Then how would I be able to thank you?

Call me when a category 3 hurricane whips the scattered debris together and creates a giant lab. That will be news.
