Three months ago, Google announced it would in early 2017 launch support for high-end graphics processing units (GPUs) for machine learning and other specialized workloads. It’s now early 2017 and, true to its word, Google today officially made GPUs on the Google Cloud Platform available to developers. As expected, these are Nvidia Tesla K80 GPUs, and developers will be able to attach up to eight of these to any custom Compute Engine machine.


These new GPU-based virtual machines are available in three Google data centers: us-east1, asia-east1 and europe-west1. Every K80 core features 2,496 of Nvidia’s stream processorswith 12 GB of GDDR5 memory (the K80 board features two cores and 24 GB of RAM).


ou can never have too much compute power when you’re running complex simulations or using a deep learning framework like TensorFlow, Torch, MXNet of Caffee. Google is clearly aiming this new feature at developers who regularly need to spin up clusters of high-end machines to power their machine learning frameworks. The new Google Cloud GPUs are integrated with Google’s Cloud Machine Learning service and its various database and storage platforms.


 The cost per GPU is $0.70 per hour in the U.S. and $0.77 in the European and Asian data centers. That’s not cheap, but a Tesla K80 accelerator with two cores and 24 GB of Ram will easily set you back a few thousand dollars, too.

The announcement comes only a few weeks before Google is scheduled to host its Cloud NEXT conference in San Francisco — where chances are we’ll hear quite a bit more about the company’s plans for making its machine learning services available to even more developers.

Dropbox, the cloud-storage provider, announced earlier today that it has exceeded the 100 million users mark. This milestone comes after the massive influx of users the company experienced this year, with Dropbox quadrupling its number of users during 2012. It’s still nowhere near the number the company would like to have, however.


Drew Houston, one of Dropbox’s founders, offered this statement. “Even 100 million is still at a single dot percentage of the people we could reach.” The cloud-storage company is up against steep odds, however, with their competition including such powerhouses as Amazon, Google, Apple, and Microsoft, all of which offer their own varieties of storage.

Still, despite Houston’s large ambitions, hitting the 100 million user mark is quite an accomplishment. Apple, for example, has 190 million users on its iCloud storage service. And Dropbox aims to offer something none of the other aforementioned providers can – a way to store data without concern for the “logo on the back of the computer or device.”

In fact, says the company co-founder, Dropbox, though providing a similar service, is in a better position overall to meet its goals and that it has a different focus. “Those companies are busy trying to build something we had four years ago,” said Houston. “We’re out front. We’re already out there and building smaller features and things. All those other companies have turf to protect, and they’re fighting a battle on a totally different front.”

The Pirate Bay Moving to the Cloud

By on October 18, 2012

File sharing website The Pirate Bay has made a drastic change to its infrastructure, moving all operations to the Cloud. Instead of physical servers located mainly in Sweden, the site will now use several cloud hosting providers scattered across several continents around the world, which should make it virtually invulnerable to police raids.


The site has been blamed for encouraging illegal file-sharing, and its servers have been the target of multiple raids, including a major raid in 2006 by Swedish police, which led to three days of downtime.


The website has also struggled with power failures and other service issues, with the site going down for nearly a day as recently as two weeks ago due to power failure. The move to Cloud servers should virtually eliminate the possibility of downtime due to power failure.


A Pirate Bay representative told the TorrentFreak website,

Moving to the cloud lets TPB move from country to country, crossing borders seamlessly without downtime. The hosting providers have no idea that they’re hosting The Pirate Bay, and even in the event they found out it would be impossible for them to gather data on the users.

If the police decide to raid us again there are no servers to take, just a transit router. If they follow the trail to the next country and find the load balancer, there is just a disk-less server there. In case they find out where the cloud provider is, all they can get are encrypted disk-images.”


A statement on the site reads:

The site that you’re at will still be here, for as long as we want it to. Only in a higher form of being. A reality to us. A ghost to those who wish to harm us.

Word Art by Wordle

By on September 27, 2009

wrdle-bigWordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends.

You may create the word clouds by copy and paste your bunch of text in the the text area, enter the url of your blog, blog feed or any other web page that has an Atom or RSS feed. After you get your word clouds, you may edit it by changing the font size, font type, font color, layout, or remove certain language from the wordcloud.

Currently Worlde supported most of the language but not Chinese and Japanese, base on the author, this is because they cannot reconize the word split for this 2 languages.

For more question, you may refer to the Wordle FAQ page.
