The Supercomputing Slump Hits HPC

Supercomputing, by definition, is an esoteric, exotic, and relatively small slice of the overall IT landscape, but it is, also by definition, a vital driver of innovation within IT and in all of the segments of the market where simulation, modeling, and now machine learning are used to provide goods and services.

As we have pointed out many times, the supercomputing business is not, however, one that is easy to participate in and generate a regular stream of revenues and predictable profits and it is most certainly one where the vendors and their customers have to, by necessity, take the …

Worth Reading: IPv4 route lookup on Linux

During the lifetime of an IPv4 datagram inside the Linux kernel, one important step is the route lookup for the destination address through the fib_lookup() function. From essential information about the datagram (source and destination IP addresses, interfaces, firewall mark, …), this function should quickly provide a decision. —Vincent Bernat @MTU Ninja

Worth Reading: DNS Hijacking is Real

Over the years hackers have hijacked many domain names by manipulating their DNS records to redirect visitors to malicious servers. While there’s no perfect solution to prevent such security breaches, there are actions that domain owners can take to limit the impact of these attacks on their Web services and users. —Lucisn Constantin @ The New Stack

IT Starts with Docker

Happy SysAdmin Day! Cheers to all of you who keep your organizations running, keep our data secure, respond at a moment’s notice and bring servers and apps back to life after a crash. Today we say, “Thank You!”

Docker Sysadmin Day

Anniversaries are a great time to reflect on accomplishments of the last year: the projects you’ve completed, the occasions you’ve saved your company money or time, the new technology you’ve learned. In a role like IT, so much can change each year as technology progresses and becomes more challenging to stay ahead of that curve. So this SysAdmin Day, we at Docker want to congratulate your past successes and prepare you for the year to come.

Containers are not just for developers anymore and Docker is the standard for packaging all kinds of applications – Windows, Linux, traditional, and microservices. Over the next few months, we’ll be covering how SysAdmins like yourself are enabling their organizations to innovate faster while saving their companies’ money by embracing containers with Docker Enterprise Edition.

Cybersecurity is the Top Internet Policy Concern in the Asia-Pacific Region

This month at the Asia-Pacific Regional IGF in Bangkok we will release the fourth annual Internet Society Survey Report on Internet Policy Issues in Asia-Pacific.

Findings from this year’s report show that cybersecurity, access, data protection, connectivity and privacy are the top five concerns for Internet users. These issues have more or less remained constant since 2014, however, not surprisingly this year cybersecurity has become the top issue.

Other issues that respondents expressed concern for relate to fake news, increasing digital surveillance that violates privacy rights, and more frequent instances of censorship and site-blocking that impact freedom of expression.

The History of The Wireless Field Day AirCheck

Mobility Field Day 2 just wrapped up in San Jose. It’s always a little bittersweet to see the end of a successful event. However, one thing that does bring a bit of joy to the end of the week is the knowledge that one of the best and longest running traditions at the event continues. That tradition? The Wireless/Mobility Field Day AirCheck.

The Gift That Keeps Giving

The Wireless Field Day AirCheck story starts where all stories start. The beginning. At Wireless Field Day 1 in March of 2011, I was a delegate and fresh off my first Tech Field Day event just a month before. I knew some wireless stuff and was ready to learn a lot more about site surveys and other great things. Little did I know that I was about to get something completely awesome and unexpected.

As outlined in this post, Fluke Networks held a drawing at the end of their presentation for a first-generation AirCheck handheld wireless troubleshooting tool. I was thrilled to be the winner of this tool. I took it home and immediately put it to work around my office. I found it easy to use and it provided great information Continue reading

Google finally gains traction in cloud services

Google has long run a distant third behind Amazon and Microsoft in the cloud services business, but it finally seems to be catching some momentum, if the most recent quarter is an indicator of future trajectory. During an earnings call with Wall Street analysts, Google CEO Sundar Pichai said that Google Cloud Platform continues to experience “impressive growth across products, sectors and geographies and increasingly with large enterprise customers in regulated sectors.” To be more specific, Pichai said Google closed three times as many $500,000-plus deals in the most recent quarter as it did in the same time period last year. Of course, that is kind of pointless without knowing the exact number. And given Alphabet, Google’s parent company, reported overall revenue of $25.8 billion for the quarter, it’s likely a few drops in the bucket. To read this article in full or to leave a comment, please click here
