Get On The Stick! ... With Cuba’s IT Underground

Necessity is the mother of invention – or in this case adaptation. Information technology in Cuba, with its heavy-handed oversight of human activity, is in a process of breaking out of the grip of the government sanctions against the freedom of information sharing and publishing.

News, information, and entertainment media in Cuba, is hard to come by unless one is able to afford the time to log on to a computer in one of the few “Cyber Cafés”, have access to a tourist hotel internet portal, is a student, or has access to a smuggled dish and secretly grab the information for later viewing and sharing - OFFLINE!

OFFLINE in Cuba is an intranet (an in-country internet) patched together through a “postal service” email communication connection that the government is having trouble shutting down. The “Whack-A-Mole” process the government is left with can not stop the viral sharing aided with the use of USB memory sticks.

Cyber-Rebels in Cuba Defy State’s Limits
By JAMES C. McKINLEY Jr. - New York Times, HAVANA - March 6, 2008

A growing underground network of young people armed with computer memory sticks, digital cameras and clandestine Internet hookups has been mounting some challenges to the Cuban government in recent months, spreading news that the official state media try to suppress.

Last month, students at a prestigious computer science university videotaped an ugly confrontation they had with Ricardo Alarcón, the president of the National Assembly.

Mr. Alarcón seemed flummoxed when students grilled him on why they could not travel abroad, stay at hotels, earn better wages or use search engines like Google. The video spread like wildfire through Havana, passed from person to person, and seriously damaged Mr. Alarcón’s reputation in some circles.
----
“It passes from flash drive to flash drive,” said Ariel, 33, a computer programmer, who, like almost everyone else interviewed for this article, asked that his last name not be used for fear of political persecution. “This is going to get out of the government’s hands because the technology is moving so rapidly.”

Cuban officials have long limited the public’s access to the Internet and digital videos, tearing down unauthorized satellite dishes and keeping down the number of Internet cafes open to Cubans. Only one Internet cafe remains open in Old Havana, down from three a few years ago.

Hidden in a small room in the depths of the Capitol building, the state-owned cafe charges a third of the average Cuban’s monthly salary — about $5 — to use a computer for an hour. The other two former Internet cafes in central Havana have been converted into “postal services” that let Cubans send e-mail messages over a closed network on the island with no links to the Internet.
----
Young people here say there is a thriving black market giving thousands of people an underground connection to the world outside the Communist country.

People who have smuggled in satellite dishes provide illegal connections to the Internet for a fee or download movies to sell on discs. Others exploit the connections to the Web of foreign businesses and state-run enterprises. Employees with the ability to connect to the Internet often sell their passwords and identification numbers for use in the middle of the night.

Hotels catering to tourists provide Internet services, and Cubans also exploit those conduits to the Web.

Even the country’s top computer science school, the University of Information Sciences, set in a campus once used by Cuba’s spy services, has become a hotbed of cyber-rebels. Students download everything from the latest American television shows to articles and videos criticizing the government, and pass them quickly around the island.
----
The video of Mr. Alarcón’s clash with students was leaked to the BBC and CNN, giving the world a rare glimpse of the discontent among the young with the system.
----
Another event many people witnessed through the digital underground was the arrival in the United States of Carlos Otero, a popular television personality and humorist in Cuba who defected in December while on a trip to Toronto.

Illegal antennas caught signals from Miami television stations, which youths turned into digital videos and shared. Though the event smacked more of celebrity news than politics, it would never have been shown on the official media.

Some young journalists have also started blogs and Internet news sites, using servers in other countries, and their reports are reaching people through the digital underground.

Yoani Sánchez, 32, and her husband, Reinaldo Escobar, 60, established Consenso desde Cuba , a Web site based in Germany. Ms. Sánchez has attracted a considerable following with her blog, Generación Y, in which she has artfully written gentle critiques of the government by describing her daily life in Cuba. Ms. Sánchez and her husband said they believed strongly in using their names with articles despite the possible political repercussions.


Shortly before Raúl Castro was elected president last week to replace his ailing brother, Fidel, Ms. Sánchez wrote a piece describing what sort of president she wanted. She said the country did not need a soldier, a charismatic leader or a great speaker, but “a pragmatic housewife” who favored freedom of speech and open elections.

Writing later about Raúl Castro’s first speech as president, she criticized his vague promises of change, saying they were as clear as the Rosetta Stone was when it was first found. Both essays would be impossible to publish in Cuba.
----
Because Ms. Sánchez, like most Cubans, can get online for only a few minutes at a time, she writes almost all her essays beforehand, then goes to the one Internet cafe, signs on, updates her Web site, copies some key pages that interest her and walks out with everything on a memory stick. Friends copy the information, and it passes from hand to hand. “It’s a solid underground,” she said. “The government cannot control the information.”

It is spread by readers like Ricardo, 28, a philosophy student at the University of Havana who sells memory sticks to other students.
----
Like many young Cubans, Ricardo plays a game of cat and mouse with the authorities. He doubts that the government will ever let ordinary citizens have access to the Internet in their homes. “That’s far too dangerous,” he said. “Daddy State doesn’t want you to get informed, so it preventively keeps you from surfing.”

Pedro, a midlevel official with a government agency, said he often surfed Web sites like the BBC and The Miami Herald at work, searching for another view of the news besides the ones presented in the state-controlled media. He predicted that the 10,000 students studying the Internet and programming at the University of Information Sciences would transform the country over time, opening up more and more avenues of information.

“We are training an army of information specialists,” he said.

Exciting USB Power Innovation For Mobility Applications

In the world of portable data collection and business mobility applications, one of the most vexing problems comes down to Ni-Cad or NiMH battery management schemes (will one have the power to do and complete the job at "hand").

An innovation that is simple but brilliant has just been introduced in England and, hopefully soon, to be available here in North America.

Batteries that recharge directly from the powered USB port of any properly port equipped computer.

Excerpts from Trusted Reviews -

USBCELL: Batteries That Recharge Through USB
Author: Gordon Kelly, Trusted Reviews - Published 20th September 2006

I love innovation - who doesn't? That said, my tastes lie specifically in the kind which make my life simpler and easier. We're talking email over post, wireless over wired, LCD over CRT and potentially now 'USBCELL' batteries over your traditional AAs.

Produced by Moixa Energy, USBCELL batteries are simply batteries that recharge from any USB port. They require no separate recharging devices, cradles or cables and can be used exactly like a normal battery. The design itself is rather like a typical memory stick with its flip top lid and they could be set to deliver the same killer blow to the battery market that memory sticks did to floppy discs.

At this stage the one unknown is how well they perform when compared to their established counterparts and how long they take to charge. The new wave is coming, however, and though they launch in the familiar AA they will soon comprise a full range of standard formats including phone and camera batteries and come with C & D size converters.

Available now and costing just 12.99 British Pounds
[ed. approximately $24.50] for two AA USBCELL batteries (including VAT and delivery from the company's website) I'm forced to say something I never thought would pass my lips: I'm quite excited about batteries.

After careful review of the manufacturer's website, here are a few Frequently Asked Questions that should help to fill in some of the understanding of this new and exciting portable equipment power innovation.

User Instructions FAQs

How long do USBCELLs take to charge through a USB port?

USBCELL will charge in about 5 hours to 90% charged, or less if the battery was not fully drained, and then enter a trickle charge mode (LED flashing). The LED will go off after this.

Can USBCELL's be charged in NiMH battery chargers?

Yes. USBCELLs can be charged in any good quality overnight or quick (5-7 hour) battery chargers designed for Nickel Metal Hydride (NiMH) batteries. The recommended charge is 250mA for 7 hours. Consult your NiMH charger manual to confirm suitability. With the cap on, they work just like a normal rechargeable NiMH battery as the circuitry is bypassed. Do not use fast chargers which claim to take less than 1 to 2 hours.

Will USBCELLs suffer from the 'memory' effect?

Rechargeable cells can be recharged hundreds of times but the lifetime will reduce slightly if cells are always partially charged or topped up. The User Guide gives instructions for how to prolong USBCELLs life and maintain best performance. However, since USBCELL is capable of several hundred charges, occasional top-ups when you need urgent power will not have a significant effect.

Can the USBCELL be used in devices that normally take 1.5V (alkaline) throw-away batteries?

Yes, USBCELLs, like other rechargeable cells, should work with almost all AA-powered devices.

Do USBCELLs require drivers to work with my computer?

No, USBCELLs draw power from the USB socket and do not need any special drivers to charge.

Can I use fast chargers to charge USBCELLs?

USBCELLs should not be used with any charger rated at a current above 600mA. In general USBCELLs should not be charged by any charger that has a charge time of less than 2 hours.

Is USBCELL faster to charge than normal rechargable batteries?

USBCELL takes about 5 hours to charge, this is normally classed as fast charging. They will charge in the same time as other rechargeable batteries of the same capacity in a normal NiMH charger.

Does the USBCELL last as long as other rechargeable batteries?

The capacity of USBCELL is 1300mAH - this is greater than some ordinary NiCd and NiMH batteries. Some new high-capacity NiMH batteries can go up to 2500mAH. However, with USBCELL you can simply recharge or top-up by plugging into a USB port rather than going off to find a wall charger and adaptor. Also, make sure that the battery is fully charged - the charge should take about 5 hours by USB and the light should go off when USBCELL is fully charged.

Does the type of USB port matter?

Most USB ports are 'powered' and capable of providing up to 500mA current at 5 volts (USBCELL should draw about half of this maximum current). Because of the AA size of USBCELL, it may be difficult to insert into some inaccessible or recessed USB ports. If it's difficult to insert, don't force it!

Can I charge from a USB hub?

USBCELLs can be charged in most powered USB hubs. These should be connected to an external power supply during use. In some powered hubs, USBCELLS can be charged even without the connection to a PC, provided that the power is connected. Some USB hubs are not separately powered, and so these may not provide enough power to each socket. If you do need to use an unpowered hub, we recommend that only one USBCELL is charged at one time, with no other high-power peripherals connected.

How do I know my USBCELL is charged, when charging in a USB port?

A small LED light at the USB plug end of each USBCELL indicates that it is charging. If the cell is already charged the LED should start flashing within 15-25 minutes and stop after a further 10 minutes of top-up charge. If the cell is less charged, the LED will stay on and the battery will continue charging until full charge is detected at which point the LED will flash for 10 minutes. If the USBCELL was fully discharged it will charge for 5 hours and then trickle charge for 90 minutes. When the LED switches off then the USBCELL is fully charged. Batteries get warm during charging, to a peak temperature when fully charged. It is therefore not recommended that you recharge batteries immediately after charging. Batteries should always be charged at room temperature.
