Nowadays, I no longer play chess; but somehow I remembered this nice little puzzle and coded a 60-line Python solver that can tackle even 100x100 boards in less than a second. Try beating this, fellow coders!"

An anonymous reader writes "Three Putnam County voters say electronic voting machines changed their votes from Democrats to Republicans when they cast early ballots last week. This is the second West Virginia county where voters have reported this problem. Last week, three voters in Jackson County told The Charleston Gazette their electronic vote for 'Barack Obama' kept flipping to 'John McCain.'"

KlaymenDK writes "Over the last decade or so, I have strived to maintain my privacy. I have uninstalled Windows, told my friends 'sorry' when they wanted me to join Facebook, had a fight with my brother when he wanted to move the family email hosting to Gmail, and generally held back on my personal information online. But since, amongst all of my friends, I am the only one doing this, it may well be that my battle is lost already. Worse, I'm really putting myself out of the loop, and it is starting to look like self-flagellation. Indeed, it is a common occurrence that my wife or friends will strike up a conversation based on something from their Facebook 'wall' (whatever that is). Becoming ever more unconnected with my friends, live or online, is ultimately harming my social relations. I am seriously considering throwing in the towel and signing up for Gmail, Facebook, the lot. If 'they' have my soul already, I might as well reap the benefits of this newfangled, privacy-less, AJAX-2.0 world. It doesn't really matter if it was me or my friends selling me out. Or does it? I'd love to hear your thoughts on the matter. How many Windows-eschewing users are not also eschewing the social networking services and all the other 2.0 supersites with their dubious end-user license agreements?"

Hugh Pickens writes "Although a variety of spore discharge processes have evolved among the fungi, those with the longest ranges are powered by hydrostatic pressure and include 'squirt guns' that are most common in the Ascomycota and Zygomycota. In these fungi, fluid-filled stalks that support single spores or spore-filled sporangia, or cells called asci that contain multiple spores, are pressurized by osmosis. Because spores are discharged at such high speeds, most of the information on launch processes from previous studies has been inferred from mathematical models and is subject to a number of errors, but now Nicholas Money, an expert on fungi at Miami University, has recorded the discharges with high-speed cameras at 250,000 frames-a-second and discovered that fungi fire their spores with accelerations up to 180,000 g, calling it 'the fastest flight in nature.' Money and his students, in a justified fit of ecstasy, have created a video of the first fungus opera."

SpuriousLogic writes to tell us that University of Arizona researchers claim to have broken a barrier in holographic technology by creating an updatable, three-dimensional display with memory. While the existing model is only able to update once every couple of minutes, and isn't particularly suited for 3d images, it is certainly a step in the right direction. "Peyghambarian is also optimistic that the technology could reach the market within five to ten years. He said progress towards a final product should be made much more quickly now that a rewriting method had been found. However, it is fair to say not everyone is as positive about this prospect as Peyghambarian. Lecturer in Electronic Engineering at Bangor University in Wales, Dr Justin Lawrence, told CNN small steps were always being made on technology like 3D holograms, but, he couldn't see it being ready for the market in the next ten years."
