You know how the mobile carriers charge you a couple cents to SMS a few characters' worth of text over their network? When you add it up, you're paying about a zillion bucks a meg for that traffic -- seriously! A space scientist from Leicester has calculated that SMS data is four times more expensive than receiving data from the Hubble space telescope.
He worked out the cost of obtaining a megabyte of data from Hubble – and compared that with the 5p cost of sending a text.
He said: “The bottom line is texting is at least 4 times more expensive than transmitting data from Hubble, and is likely to be substantially more than that.
“The maximum size for a text message is 160 characters, which takes 140 bytes because there are only 7 bits per character in the text messaging system, and we assume the average price for a text message is 5p. There are 1,048,576 bytes in a megabyte, so that's 1 million/140 = 7490 text messages to transmit one megabyte. At 5p each, that's £374.49 per MB - or about 4.4 times more expensive than the ‘most pessimistic’ estimate for Hubble Space Telescope transmission costs.”
Dr Bannister said it had been difficult to work out exactly how much Hubble data transmission costs. So he contacted NASA who gave him a firm figure of £8.85 per megabyte (MB) for the transmission of data from HST to the Earth.
CutiePi is a tablet based on the Raspberry Pi: compact enough, but more open, versatile and hacker-friendly than mainstream models from Apple, Microsoft or the Google coprosperity sphere. CutiePi is a complete Raspberry Pi in a tablet form factor, minus the trouble of connecting monitor or power supply. It’s slimmer because of using Compute Module, […]
I am addicted to Thinkpads in large part because of the trackpoint (AKA "The Nipple") -- the little wiggly joystickbetween the G, H and B keys that allows me to control fine mouse-movements without bending my hand into the RSI-inducing trackpad position; between that and the amazing, best-in-class warranties, I am a committed Thinkpad user, […]
You can buy microcontrollers for as little as 3 cents, if you order a lot of them, a staggeringly cheap number even if you’re so young you don’t know a Zilog Z80 was $10 in 1978 money. But are these cheapo parts any good? Hackaday says they’re terrible, but Tim finds a role. [it] surely […]
The field of data analytics is growing as fast as the internet itself. Self-driving cars, airline pricing, and huge marketing campaigns are all driven by the insights that data scientists can distill out of vast sums of information. Even with the help of powerful software like Python, it’s a highly skilled position. But those skills […]
If you’re marketing on the web, your Google-fu needs to be strong – and up to date. Without a firm grasp on what drives traffic, you’ll never be able to take the wheel. That’s why even if you know where to put your keywords, a little extra effort goes a long way on any marketer’s […]
Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
