Twitter's had a bad couple of weeks.

First, the Boston marathon bombings and subsequent manhunt led many (including me) to question the role of fast-moving, potentially inaccurate real-time Twitter reporting and its effect on mainstream news.

Then today, a false tweet from a hacked Associated Press Twitter account claimed that the White House had been bombed and that President Obama had been injured. The news caused a sudden plunge in the stock market (and, one can probably assume, some massive profit-taking by the hackers).

Twitter has always had an accuracy problem. It's a lot of voices, its information … Read more

Eyeball a car magazine or two on a newsstand and there's a good chance you'll spot a 200-mile-per-hour dream machine gracing the cover. Why not? They're gorgeous weapons of speed, and they all sell for more than the price of your house. Supercar MSRP inflation shows no signs of letting up, all (three) of the $3.9 million, 750-horsepower Lamborghini Venenos are spoken for. Ferraris are priced somewhat more competitively; the legendary Italian maker will soon offer 499 editions of their $1.15 million carbon-fiber-bodied, hybrid V-12/electric LaFerrari, which has 963 horsepower and can reach 217 … Read more

Dear Samsung: What just happened?

In the middle of a red-hot conversation about women in technology, the resurgence of the equal-pay discussion, and Sheryl Sandberg reigniting the very concept of feminism in America, Samsung delivered a Galaxy S4 launch event that served up more '50s-era stereotypes about women than I can count, and packaged them all as campy Broadway caricatures of the most, yes, offensive variety.

To be fair, everyone in Samsung's bizarre, hourlong parade of awkward exchanges, forced laughs, and hammy skits was a stereotype. The kid was lispy, tow-headed, and tap-dancing (the little girl did ballet, of … Read more

Most of the headphones I've tested over the years weren't designed to have a neutral balance of bass, midrange, and treble frequencies. Manufacturers are well aware that most people like bass, and that buyers tend to favor one headphone over another based on how much bass it produces. I think that's obvious, but a recent study cited in Brent Butterworth's blog countered that assumption. "The Relationship between Perception and Measurement of Headphone Sound Quality," a paper by Sean Olive and Todd Welti presented at last October's Audio Engineering Society convention found that a … Read more

Years ago, long before the dawn of the DVD or Blu-ray formats, consumer video was strictly all-analog, from the very first broadcasts right up to the introduction of the LaserDisc. The 12-inch, double-sided LaserDisc looked like a giant CD, but the video was analog encoded on two single-sided aluminum discs layered in plastic. The discs that debuted in 1978 had analog audio soundtracks, but later discs featured stereo digital sound. Millions of players were sold in the U.S., but LaserDisc was, even during the height of its popularity, a niche format that appealed mostly to videophiles. It had much … Read more

What does a 120-year-old Thomas Edison cylinder record player have in common with a brand-new $299 Big Jambox Bluetooth speaker? Both play music in monophonic sound. Everything old is new again.

Home audio was strictly a single-speaker pursuit from the dawn of recorded sound through the late 1950s, when stereo changed the way we listen to music. Multichannel home theater's popularity peaked in the late 1990s, but starting with iPods and sound-bar speakers, mono was back in style. More recently sales of battery-powered, mono Bluetooth speakers started to take off. While these lo-fi systems may contain stereo pairs of … Read more

Way down in the fine print about Apple's upcoming iOS 6, you'll find a little note that says new features like Flyover and turn-by-turn directions are only available on the iPhone 4S, or the iPad 2 or higher.

A note immediately below that says Siri is only available on the iPhone 4S or third-generation iPad.

Since the iPhone 3GS, iPhone 4, and iPad 2 are all actively for sale and still being marketed by Apple, I have to wonder: is Apple on the road to fragmenting the iOS experience? Could there come a future when not only do … Read more

Features like Bluetooth audio add value to products, so they raise the price of BT-equipped gear. I don't have a problem with that, but I'm surprised how much sound quality people are willing to give up just to have wireless audio.

Cheap Bluetooth add-ons like the $25 Belkin Bluetooth Music Receiver or the $40 Logitech Wireless Speaker Adapter can stream tunes from a smartphone, iPod Touch, iPad, or other tablets sans wires. That's nice, but the processing sounds awful -- gritty harsh, limits bass oomph, and has unpleasant treble -- compared with just running a wire to … Read more

Update: May 17, 2012 Do I get results, or what? Less than a day after this column posted, Comcast announced it would ditch its 250GB data cap in favor of a 300GB cap with the option to buy additional 50GB chunks for $10 each. Not bad, although it's amusing timing given their current fight over Net neutrality and cap-free Xfinity on-demand streaming.

Bandwidth caps, the death of unlimited data plans, throttling, "data hog" accusations...I get it. Pay-per-use bandwidth is inevitable: the end of unlimited Internet access is at hand. Bandwidth is a limited resource, especially on … Read more
