On GCP you don't pay for minutes you don't use, and now it's easy to also avoid paying for cores or RAM you don't use.

Stop making GCP sounds appealing or fix the bug that bans customers from Europe without a VAT. Preferably the latter please :)

"We looked at the latency of Google Compute Engine in the US Central region. Google's cloud has a latency performance characteristic that's unique among the largest cloud providers. Latency performance on any cloud fluctuates, sometimes wildly, whether you break it down by month, day, hour or even minute. But not Google's. Google's latency performance tends to have far less pronounced peaks and valleys."
Customers of any cloud should cheer any new installation, but for companies that prize consistent cloud latency performance throughout the day, Google's intent to establish almost a dozen new 'cloud regions' should be especially welcome.

+Felix Felix if you're using just the storage components, e.g. Google Drive or Google Cloud Storage, nothing is stopping you from uploading only encrypted files; just don't keep the keys in any Google storage. Encrypted e-mail is more complicated, I guess possible if you use only the IMAP interface to GMail.

The DOE published its first report on datacenter energy usage since 2008 (the actual report is at http://eta.lbl.gov/sites/all/files/lbnl-1005775.pdf). Summary: thanks to much better efficiency, energy usage has flattened out despite the growth in internet usage.

I'm happy Google contributed to this positive effect by publishing its efficiency since 2008 and by promoting techniques for more efficient use, starting with the first datacenter efficiency summit in 2009 (https://www.google.com/about/datacenters/efficiency/external/2009-summit.html).

I'm even more optimistic than the study authors and would predict that total energy usage will go down as more IT users transition to public clouds, which not only have the most efficient buildings but through consolidation and elastic scaling reduce the energy per application (see http://www.informationweek.com/cloud/google-apps-cuts-gsa-energy-costs/d/d-id/1104908? for an example). And on the client side, mobile devices use much less power than desktops, reducing total IT energy usage even more.
Second study of its kind in history shows overall growth in data center energy use has flattened Read More

Chillers cool water (with air or refrigerant). Then CRAH cool air with water. Then servers are cooled with air. Can't we remove Air cooling altogether to save energy? Can we not directly cool servers with water with NO air conditioning? That's the Design Tango Tech is running with. Sorry for the promotion blurb, but thought many of you would be intreagued, given that CRAH can consume as much as 40% of cooling energy.

What appears to be sadness, may be hapiness, depending on the age/experience of the observer;
people tends to develop critical thinking with time;
it seems that in today's age of infomation there is hope for humanity to learn faster than ever before, I'd like to see that working to be honest.

I am a very happy +DigitalOcean user happy to see it getting compared/ benchmarked with Google and Microsoft. Kudos +DigitalOcean

I'd say CloudML rocks, but I'll take "soars".

Short but thought provoking essay on innovation by +Luiz André Barroso​.
 
Google's re:work team has published in their blog a one-pager I wrote internally at Google a couple of years ago about one of our most successful (and less publicized) approaches to innovation.
Google’s “moonshot factory” is inspiring and ambitious, but there’s a less talked-about route to many of Google’s great achievements -- the consistent, short-term, incremental “roofshots” that make our products better year after year.

Most technological progress is made by "Roofshot" improvements. The Google search engine is an example as the author describes.

Internet users and our customers in Japan today should notice things seem to be moving a bit…FASTER. Today, our FASTER subsea cable between Japan and the U.S. officially entered into service.

Fun facts:
- FASTER has 60Tbps (terabits per second) total capacity — more than any active subsea cable, and 10 million times faster than your cable modem
- This cable is the first of its kind, with multiple colors (100) of light transmitted over various frequencies
- Every ~60km a repeater to re-energizes the light as it travels over 9,000km across the ocean floor

FASTER is one of just a few hundred submarine cables connecting various parts of the world, which collectively form an important backbone that helps run the Internet.

This is particularly exciting news for our GCP customers in the Japan, as we’ll be opening our Google Cloud Platform region in Tokyo later this year. Looking forward to a more reliable, more secure and FASTER public cloud!

Sad to see that a popular email provider in my home country of Switzerland encrypts 0% of their outgoing email :-(

(https://www.google.com/transparencyreport/saferemail can show you this data about any provider.)

Funny: the "@Swisscom.ch /@Swisscom.com" domain has outgoing encryption active ... but this is not a free service ;-)
