OpenStack users talk benefits, challenges of open source clouds

A couple of years ago tech executives at FICO wanted to update their infrastructure. “OpenStack seems to be the wave of the future, so we gave it a run,” says Donald Talton, senior manager of platform operations and cloud engineering at the credit rating agency. SolidFire Donald Talton FICO considered using VMware, but felt that the “momentum” of OpenStack was stronger, Talton says. And so began FICO’s use of OpenStack’s IaaS open source private cloud software. Talton says it’s been great, though that doesn’t mean it’s been easy.To read this article in full or to leave a comment, please click here

IBM lines up all-flash storage to help power cognitive computing

IBM is expanding its flash storage lineup to power cloud data centers that carry out so-called cognitive computing.The company’s newest FlashSystem arrays, introduced Wednesday, combine its fast and relatively affordable FlashCore technology with a scale-out architecture designed to be easy to expand.Cognitive computing, which IBM defines as real-time data analysis for immediate, automated decision-making, is at the heart of much of IBM’s current technology push for enterprises and service providers. Its Watson technology is the star of the show but only the most visible part of what the company is doing in this space. An example of cognitive computing is a mobile operator analyzing information about phone call quality to make decisions on the fly about changes in the network, said Andy Walls, an IBM Fellow and CTO for flash systems.To read this article in full or to leave a comment, please click here

Apple stumbles in the world’s biggest smartphone market

Last year, Apple was on a gravy train in China. Sales of the iPhone were booming, and the country looked poised to overtake the U.S. in its contribution to Apple’s business. Suddenly, things don't look so rosy.Apple reported Tuesday that its first quarter revenue from Greater China declined 26 percent from the same period in 2015, a turnaround that contributed to Apple's first year-over-year revenue decline in more than a decade.To read this article in full or to leave a comment, please click here

Apple’s quarterly revenue drops for the first time since 2003

Apple earlier today released its Q2 2016 earnings and the results might leave investors a bit wary. When the dust settled, Apple reported $10.5 billion in profits on the back of $50.6 billion in revenue. And while those figures are certainly impressive, they are markedly lower than what Apple reported during the company's second fiscal quarter in 2015 when it posted $58 billion in revenue.Notably, this marks the first time that Apple's quarterly revenue experienced a year over year decline since 2003.Product wise, Apple sold 51.2 million iPhones, a significant drop-off from the 61.17 million iPhones Apple sold during the same quarter a year-ago. In fact, Apple's most recent quarter represents the first time that quarterly iPhone sales have dropped off. To read this article in full or to leave a comment, please click here

My next scan

So starting next week, running for a week, I plan on scanning for ports 0-65535 (TCP). Each probe will be completely random selection of IP+port. The purpose is to answer the question about the most common open ports.

This would take a couple years to scan for all ports, so I'm not going to do that. But, scanning for a week should give me a good statistical sampling of 1% of the total possible combinations.

Specifically, the scan will open a connection and wait a few seconds for a banner. Protocols like FTP, SSH, and VNC reply first with data, before you send requests. Doing this should find such things lurking at odd ports. We know that port 22 is the most common for SSH, but what is the second most common?

Then, if I get no banner in response, I'll send an SSL "Hello" message. We know that port 443 is the most common SSL port, but what is the second most common?

In other words, by waiting for SSH, then sending SSL, I'll find SSH even it's on the (wrong) port of 443, and I'll find SSL even if it's on port 22. And all other ports, too.

Can AI beat you at Foosball? Yes. Yes it can

AI has already proved its prowess in chess, Jeopardy and the ancient game of Go, but it's now come out victorious in yet another arena: the classic game of Foosball.A group of computer engineering students at Brigham Young University have spent the past semester creating a robotic, computer-controlled Foosball table with the goal of beating human players. The table is constructed so that a camera mounted above can track the movement of the ball, while an algorithm controls the rods on which the plastic players are attached.To read this article in full or to leave a comment, please click here

Dell partners up to address the networking needs of the digital enterprise

Dell has made a tremendous amount of noise in the media over the past few months caused by the ripple effect of its acquisition of EMC. Whether one thinks the merger is a good idea or not, it’s a fact that the merger will have a significant impact on the storage and server industries.Today, Dell announced plans that will bolster its position in networking. The move to become a digital organization is a trend that’s now being felt across almost all companies in every vertical. The building blocks of digital are technologies such as cloud, mobile, big data and analytics. What do these have in common? They’re all network-centric, meaning the network plays a key role in the shift to a digital enterprise.To read this article in full or to leave a comment, please click here

Worth Watching: Must privacy give way?

Projected benefits of data science and the paradigm of big data are not compatible with the regulation of information collection prompted by concerns over privacy. So goes a compelling and popular argument. Dr. Nissenbaum will challenge this perspective not only because it plays suspiciously well with the dominant business model of the commercial information industry but also because it rests on misconceptions and ambiguities of key terms. -Brown University

Microsoft outlines new features coming in Windows 10 Anniversary Update

Microsoft has posted what it calls “a major build” of Windows 10, with significant new features scheduled for the Anniversary Update due this summer. The news has been detailed by Gabe Aul, vice president of the engineering systems team in the Windows group.Microsoft posted Windows 10 Insider Preview Build 14328 for both PC and Mobile to the Windows Insiders Fast ring, which gets more rapid updates than Insider, and thus isn’t for everyone. You’re getting builds hot off the compiler, so to speak, which means they are liable to be buggier. This is for true testers.To read this article in full or to leave a comment, please click here

Multi-tenant sFlow

This article discusses how real-time sFlow telemetry can be shared with network tenants to provide each tenant with a real-time view of their slice of the shared resources. The diagram shows a simple network with two tenants, Tenant A and Tenant B, each assigned their own subnet, 10.0.0.0/24 and 10.0.1.0/24 respectively.

One option would be to simply replicate the sFlow datagrams and send copies to both tenants. Forwarding using sflowtool describes how sflowtool can be used to replicate and forward sFlow and sFlow-RT can be configured to forward sFlow using its REST API:
curl -H "Content-Type:application/json" \
-X PUT --data '{"address":"10.0.0.1","port":6343}' \
http://127.0.0.1:8008/forwarding/TenantA/json
However, there are serious problems with this approach:
  1. Private information about Tenant B's traffic is leaked to Tenant A.
  2. Information from internal links within the network (i.e. links between s1, s2, s3 and s4) is leaked to Tenant A.
  3. Duplicate data from each network hop is likely to cause Tenant A to over-estimate their traffic.
The sFlow-RT multi-tenant forwarding function addresses these challenges. The first task is to provide sFlow-RT with an accurate network topology specifying the internal links connecting the Continue reading
