A light tank, called the Honey in Britain. Machine gun ports in the hull help distinguish this model, as well as the hexagonal commander's hatch. The M3A1 ditched the hull mounted side machine guns.
At least this mudhole is shallow, one in France swallowed up a later M5 model in 1944.
June 1942. "Why greases must be saved. Introducing two good soldiers of the home front: the housewife who saves her waste household fats and greases, and the butcher to whom she gives this salvaged fat after she has collected at least one pound, strained it through a metal sieve and poured it into a large, wide-mouthed can. Butchers displaying the poster shown here will pay househoulders for the fat, and sell it to rendering plants thereby turning this valuable material into industrial channels where it will be processed into ammunition for America's fighting men." Medium format negative by Ann Rosener for the OWI.
"It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice. There had been some question whether the bright material was salt. Salt can't do that."
The chunks were left at the bottom of a trench informally called "Dodo-Goldilocks" when Phoenix's Robotic Arm enlarged that trench on June 15, during the 20th Martian day, or sol, since landing. Several were gone when Phoenix looked at the trench early today, on Sol 24. [University of Arizona Mars Phoenix Mission]

For those of us who work on the ‘front end development’ side of things, there’s a careful balance we hang in regarding new browser releases. The short version is that as new browsers approach their release candidate status, we need to be checking and double checking our work in them to make sure that their change logs don’t break our work.
At the same time, there’s a known issue with the fact that, more often than not, running the latest beta or release candidate alongside with the production version (and, if you’re a really good developer, one previous version back from the most current production release to take care of things). Internet Explorer is notorious for this and I recall the headaches I went through beta testing it. I essentially resolved to (and continue to resolve to) use multiple virtual machines, one for each version of IE.
[Dave Martorana] created a little launcher app that, when copied to your Apps folder along with the accompanied Firefox3.app file (appropriately renamed so it wont overwrite the stable version), will let you create and/or select an additional profile, as well as the version of Firefox that you wish to use. It’s clean, it’s simple, and it works.
Neat. I have to run 2.0 for web development, but the rest of my crap can go in 3.0
Nonbovine Ruminations: Oil: How will we ever do without it?

Oil, and the price, supply, and demand thereof, is all in the news today, thanks mainly to Bush's declaration that the US should lift its moratorium on outer shelf drilling. This has led to a groundswell of talk about oil and gasoline prices, American dependence on foreign oil (note polling methodology used), alternative fuels, and all sorts of other things.
The problem is that virtually all of this talk is rearranging deck chairs on the Titanic. Unless you're one of those crazy people who believes in the abiogenic theory of oil origin (which asserts that the Earth contains secret, unlimited supplies of hydrocarbons if you just drill deep enough; while it may be the case that some subcrustal hydrocarbons are of nonbiological origin, that fact will not somehow make their supply limitless), there's no way of escaping the fact that the amount of available oil on the planet is either fixed or increasing very slowly, and that we're drawing down that finite supply at an alarming rate. A 2007 report puts world reserves of crude oil at between 1119 and 1317 billion barrels. Meanwhile, the world consumption of oil (per OPEC in 2006) was 78.3 million barrels a day, or 28.6 billion barrels a year. That means we have between 39 and 46 years of oil left at our current consumption rate, after which we will be out.
“I’d say if you can’t bother to build it yourself, get potential customers lined up, build revenue on an easier offshoot, or convince someone else to build it in their spare time, then you should reevaluate whether you are an entrepreneur.”
Luca says:
“The idea is the easy part. If you are a first-time entrepreneur, try scaling down your concept to something whose value you can prove with friends & family money, then go to professional investors. If your idea does not lend itself to such an approach, try your hand first with something you can bootstrap.”
Ben says:
“An idea has a dollar value of $0. If you don’t believe in the idea enough to commit your cash/sweat equity to build it or a version of it to show it can work, why should friends, fools and family?”
Any time you picture a body of water larger than a puddle, one of the first things that comes to mind are the rolling waves, or the surf lapping at the shore. Well, at least that's what happens with me... But waves are much more than tranquil anomalies, they can be dangerous and destructive to any vessel in almost any body of water. Understanding how waves are made, how they normally behave, and how to predict their response to weather can make the difference between a smooth, comforting time on the water and a bumpy, frightening experience.
The first rule of waves, especially in the open ocean, is that there are no rules. Kind of a hypocritical statement considering the intent behind this article, but it is a hard, cold fact. There are simple physical factors that makeup the "normal" wave, but within the forces of nature, there a myriad of other factors that need be considered into the equation. Regardless, an understanding of what makes a "textbook" wave can be of considerable merit to the sailor. What we will examine here are the laboratory examples of wave creation. How, in a perfect world, waves would behave. In reality, alternating weather patterns, varying water depths, opposing currents, fetch obstruction and a multitude of other factors may change the way waves in a particular area react.
