Making Sense of Revision-Control Systems 268

ChelleChelle writes "During the past half-decade there has been an explosion of creativity in revision-control software, complicating the task of determining which tool to use to track and manage the complexity of a project as it evolves. Today, leaders of teams are faced with a bewildering array of choices ranging from Subversion to the more popular Git and Mercurial. It is important to keep in mind that whether distributed or centralized, all revision-control systems come with a complicated set of trade-offs. Each tool emphasizes a distinct approach to working and collaboration, which in turn influences how the team works. This article outlines how to go about finding the best match between tool and team."

Linux-Friendly Label Printer Recomendations? 188

pdkl95 writes "I have been using some small, simple desktop label printers for quite a while now. Unfortunately, it's rapidly becoming clear that my printing needs are for something far more 'industrial strength.' Several of the label printers have failed, and they never really had the management features I wanted. So, does anybody have recommendations on label printers, that can hold up to a quite heavy load? The catch is that I'm printing to them from CUPS under Linux, and it seems like specialty-printers are a windows-centric field."

Novel Algae Fuel-Farming Method Gets Big Backing 176

Al writes "Dow Chemical has given its backing to a Florida startup called Algenol Biofuels that hopes to produce commercial quantities of ethanol directly from algae without the need for fresh water or agricultural lands. Dozens of companies are trying to produce biofuels from algae, mostly by growing and harvesting the microorganisms to extract their oil. Algenol has chosen instead to genetically enhance certain strains of blue-green algae, also known as cyanobacteria, to convert as much carbon dioxide as possible into ethanol using a process that doesn't require harvesting to collect the fuel. Algenol's bioreactors are troughs covered by a dome of semitransparent film and filled with salt water that has been pumped in straight from the ocean. The photosynthetic algae growing inside are exposed to sunlight and fed a stream of carbon dioxide from Dow's chemical production units. The goal is to produce 100,000 gallons of ethanol annually."

Comment Posting code written while at school... (Score 1) 333

While I think failing the student is a little extreme, but the teacher might have had a different take on it. Some schools have intellectual property rights on what you create during/for class. Now, I admit, any school that fights over a bubble sort or something of similar ease has issues greater than a little lawsuit. But some college classes run as if this were a "Workplace" where your "assignment" is something akin to what you might run into IRL. So, immediately after the due date for the assignment the programmer goes posting the code on the net would probably be fired or otherwise supremely reprimanded if this was an actual business. In short, while it wasn't expressly forbidden, it also wasn't expressly allowed. While the teacher shouldn't have gone to such an extreme step as failing immediately (maybe say that the student will get a 0 or something for that grade), the student should be aware of why the teacher is requesting such an act. Then again... it could all be blown out of proportion and people should just laugh and move on.
