Glenn Reynolds of Instapundit has a piece in Popular Mechanics about the growing trend of cops bullying photographers who take pictures in public places, and why officials who believe such photography is against the law are mistaken.Taking Photos In Public Places Is Not A Crime: Analysis (popularmechanics.com, Illustration by Rui Ricardo, courtesy Popular Mechanics)I believe there is a good case to be made that having lots of cameras in the hands of citizens makes us more, rather than less, safe. Here's how bad it has gotten: Not long ago, an Amtrak representative did an interview with local TV station Fox 5 in Washington, D.C.'s Union Station to explain that you don't need a permit to take pictures there--only to be approached by a security guard who ordered them to stop filming without a permit.
Legally, it's pretty much always okay to take photos in a public place as long as you're not physically interfering with traffic or police operations. As Bert Krages, an attorney who specializes in photography-related legal problems and wrote Legal Handbook for Photographers, says, "The general rule is that if something is in a public place, you're entitled to photograph it." What's more, though national-security laws are often invoked when quashing photographers, Krages explains that "the Patriot Act does not restrict photography; neither does the Homeland Security Act." But this doesn't stop people from interfering with photographers, even in settings that don't seem much like national-security zones.

A freelance photographer who was taking pictures of a BP refinery in Texas was detained by a BP security official, local police and a man claiming to be with the Department of Homeland Security, according to nonprofit news org ProPublica. The photographer was working on a story about multiple large toxic releases at the BP refinery which happened just before the big Gulf oil blowout. From NBC News:
The photographer, Lance Rosenfield, said he was confronted by the officials shortly after arriving in Texas City, Texas, to work on a story that is part of an ongoing collaboration between PBS and ProPublica.
Rosenfield was released after officials looked through the pictures he had taken and took down his date of birth, Social Security number and other personal information, the photographer said. The information was turned over to the BP security guard who said this was standard procedure, ProPublica quoted Rosenfield as saying.
Rosenfield, a Texas-based freelance photographer, said he was followed by a BP employee after taking a picture on a public road near the refinery, and then cornered by two police cars at a gas station. The officials told Rosenfield they had the right to look at the pictures taken near the refinery and if he did not comply he would be "taken in," the photographer said according to ProPublica.

The Digital Foundry blog has done an analysis of recently launched cloud gaming service OnLive, measuring latency across several different games. Quoting: "In a best-case scenario, we counted 10 frames delay between button and response on-screen, giving a 150ms latency once the display's contribution to the measurement was removed. Unreal Tournament III worked pretty well in sustaining that response during gameplay. However, other tests were not so consistent, with DiRT 2 weighing in at 167ms-200ms while Assassin's Creed II operated at a wide range of between 150ms-216ms. ... OnLive says that the system works within 1000 miles of its datacenters on any broadband connection and recommends 5mbps or better. We gave OnLive the best possible ISP service we could find: Verizon FiOS, offering a direct fiber optic connection to the home. Latency was also reduced still further simply due to the masses of bandwidth FiOS offers compared to bog standard ADSL: in our case, 25mbps."

This article collects together a number of useful linux command-line tricks from Linux Format.
Everyone knows the answer to the question of life, the universe and everything is “42″, but for the first time we can reveal the question. It is this: how many command-line tricks must a man memorise? You see, graphical user interfaces are all well and good, but when you want to get real work done it’s time to switch to the terminal.
And so, we squeezed our brain cells, dug through dusty piles of old issues of Linux Format, and sat reflecting quietly over many a pint of ale, all with the goal of bringing you this: 42 awesome new command line tricks we think you ought to commit to memory. We’ve tried to include a few that are easier for our, er, less-experienced readers to enjoy, but we think even the most hardened Linux veteran will learn something new over the next 12,000 words.
Jeff Atwood over at Coding Horror has put up a post on his experience with his latest SSD. Sounds promising!
Intel was the only game in town for about a year, but fortunately for us consumers, the competition finally caught up. The new Indilinx controller models, such as this Crucial 128 GB SSD, are just as fast as the X25-M. And, best of all, they’re cheaper, while also offering a not-insubstantial bump to 128 GB of storage!
I picked this model up for $325 plus tax and shipping. And, frankly, I was blown away by the performance difference compared to the 300 GB Velociraptor I had in my system before. That drive is not exactly chopped liver; it’s incredibly fast by magnetic platter drive standards. But it’s beyond slow next to the latest SSDs.
This post on Freewaregenius lists a number of useful Windows utilities that will make your Windows desktop even better. Check out the rest of their site for other useful freeware programs.
When I first thought of this post, I more or less knew what programs I wanted to list here. The common theme that brought these together was that they were all really cool Windows “enhancements”: i.e. apps that tweak or change the way we work with files, folders, applications, or the system environment itself (or, apps that brings functionality to the Windows environment that could or should have been a built-in option in Windows
).
When you need to make sure your data is truly destroyed, use one of these.
Manual Hard Drive Destroyer
Government specifications require that in an emergency situation a hard drive needs to be destroyed so that a person or persons can not spin the drive. This must be done quickly and reliably. The MHDD meets this requirement. It takes less than 15 seconds to destroy each hard drive. All one needs to do is to insert the proper drive height adaptor (if applicable) into the slot and crank the handle 8 rotations. The internal workings of the unit press down on the drive, bending it approximately 90 degrees. The MHDD then pushes the destroyed hard drive out for easy disposal.
Listen to the beat of a binary counter!
This is an experiment, where I count one byte up – from 00000000 to 11111111. Decimal spoken, this is from 0 to 255. I have assigned a sound to each bit and when it switches from 0 to 1, the sound is played.
Published in Wired in 1996, this is still an excellent article written by Neal Stephenson, who travels across the globe to document how undersea communications cable are laid. While the article is very long (56 pages), it makes for fascinating reading.
FLAG, a fiber-optic cable now being built from England to Japan, is a skinny little cuss (about an inch in diameter), but it is 28,000 kilometers long, which is long even compared to really big things like the planet Earth. When it is finished in September 1997, it arguably will be the longest engineering project in history. Writing about it necessitates a lot of banging around through meatspace. Over the course of two months, photographer Alex Tehrani and I hit six countries and four continents trying to get a grip on this longest, fastest, mother of all wires. I took a GPS receiver with me so that I could have at least a general idea of where the hell we were. It gave me the above reading in front of a Chinese temple around the corner from the Shangri-La Hotel in Penang, Malaysia, which was only one of 100 peculiar spots around the globe where I suddenly pulled up short and asked myself, “What the hell am I doing here?”
Wired has a fascinating story about two AI researchers, both of whom committed suicide.
In 1991, Singh went to MIT to study artificial intelligence with his idol and soon attracted notice for his passion and mental stamina. Word was that he had read every single one of the dauntingly complex books on the shelves in Minsky’s office. A casual conversation with the smiling young researcher in the hallway or at a favorite restaurant like Kebab-N-Kurry could turn into an intense hour-long debate. As one fellow student put it, Singh had a way of “taking your idea and showing you what it looks like from about 50 miles up.”
The field of AI research that Singh was joining had a history of bipolar behavior, swinging from wild overoptimism to despair. When 2001 came out in the late ’60s, many believed that a thinking machine like HAL would exist well before the end of the 20th century, and researchers were flush with government grants. Within a few years, it had become apparent that these predictions were absurdly unrealistic, and the funding soon dried up.
Here’s another impressive homebrew computer. It was built with more than 200 ICs, and has similar capabilities to the original 8086 processor. It was recently demoed running a port of Minix 2.
Magic-1 is a completely homebuilt minicomputer. It doesn’t use an off-the-shelf microprocessor, but instead has a custom CPU made out of 74 Series TTL chips. Altogether there are more than 200 chips in Magic-1 connected together with thousands of individually wrapped wires. And, it works. Not only the hardware, but a full software stack. There’s a ANSI C cross-compiler for Magic-1 (retargeted LCC), a fully multi-user, multi-tasking port of the Minix 2 operating system. a TCP/IP stack and hundreds of programs.
