WhatsApp reduces spam, despite end-to-end encryption

Can a spam filter work even without reading the content of your messages?WhatsApp thinks so. Since last April, the messenger app has been successfully fighting spam abuse, even as it’s been using end-to-end encryption.That encryption means that no one -- not even WhatsApp -- can read the content of your messages, except for the recipient.More privacy, however, can raise issues about spam detection. If WhatsApp can’t scan your messages for suspicious content, say for advertisements peddling cheap Viagra, then how can it effectively filter them out?To read this article in full or to leave a comment, please click here

AMD sets Ryzen up for a strong start as chip battle with Intel looms

As a pesky underdog, AMD challenged Intel in chip innovation until the mid-2000s. AMD churned out innovations like dual-core and 64-bit chips, which kept Intel on its toes.But some disastrous technological and management decisions cost AMD dearly, and over time, buyers began to consider its processors inferior to Intel's chips. Intel ran away with PC and server chip market share.AMD now is looking to rally its dwindling fan base with a series of Zen-based chips this year for desktops, servers, and laptops. The hyped-up Zen chips are expected to be good, and even Intel readily acknowledges the stiff competition coming its way.AMD promises that Zen chips will deliver a 40 percent improvement in instructions per cycle, an important metric for chip performance. That number is impressive, considering most chips based on a new architecture have typically boasted CPU improvements of up to 20 percent.To read this article in full or to leave a comment, please click here

Juniper heads to the clouds with Unite

Not to state the obvious, but the cloud has been growing in popularity over the past decade. However, contrary to much of the rhetoric I hear about today, the cloud is not going to kill of private data centers any time soon. The explosion in data has driven growth in both private data centers and public clouds.Underscoring that point is that almost all the IT leaders I speak to plan to do some kind of hybrid cloud where they leverage the strengths of both.The cloud is a new compute model, but what’s different about it from other compute paradigms before it is that it is highly network centric. Everyone loves the cloud. It’s great, it’s elastic and a bunch of other things. But it won’t provide the results companies are looking for without the right network underneath it. To read this article in full or to leave a comment, please click here

Docker’s namespaces – See them in CentOS

In the Docker Networking Cookbook (I got my copy directly from Pact Publishing), Jon Langemak explains why the iproute2 utilities can't see Docker's network namespaces: Docker creates its namespace objects in /var/run/docker/netns, but iproute2 expects to find them in /var/run/netns.

Creating a symlink from /var/run/docker/netns to /var/run/netns is the obvious solution:

 $ sudo ls -l /var/run/docker/netns  
 total 0  
 -r--r--r--. 1 root root 0 Feb 1 11:16 1-6ledhvw0x2  
 -r--r--r--. 1 root root 0 Feb 1 11:16 ingress_sbox  
 $ sudo ip netns list  
 $ sudo ln -s /var/run/docker/netns /var/run/netns  
 $ sudo ip netns list  
 1-6ledhvw0x2 (id: 0)  
 ingress_sbox (id: 1)  
 $

But there's a problem. Look where this stuff is mounted:

 $ ls -l /var/run  
 lrwxrwxrwx. 1 root root 6 Jan 26 20:22 /var/run -> ../run  
 $ df -k /run  
 Filesystem   1K-blocks Used Available Use% Mounted on  
 tmpfs      16381984 16692 16365292  1% /run  
 $

The symlink won't survive a reboot because it lives in a memory-backed filesystem. My first instinct was to have a boot script (say /etc/rc.d/rc.local) create the symlink, but there's a much better way.

Fine, I'm starting to like systemd

Systemd's tmpfiles.d is a really elegant way of handling touch files, symlinks, empty Continue reading

Worth Reading: Massive networks of fake accounts on Twitter

Massive collections of fake accounts are lying dormant on Twitter, suggests research. The largest network ties together more than 350,000 accounts and further work suggests others may be even bigger. UK researchers accidentally uncovered the lurking networks while probing Twitter to see how people use it. Some of the accounts have been used to fake follower numbers, send spam and boost interest in trending topics. —BBC

In treason case, Russia alleges security experts aided US

Two officers of the Russian Federal Security Service (FSB) and a cybercrime investigator from Kaspersky Lab have reportedly been charged with treason for helping U.S. intelligence services. The arrests of Ruslan Stoyanov, the head of the computer incidents investigation team at Kaspersky, and Sergei Mikhailov, the deputy head of the Information Security Center at the FSB, happened in early December and were reported in the Russian media last week. Since then, the arrest of a third FSB officer named Dmitry Dokuchayev, who also worked for the agency's Information Security Center, came to light, and the investigation is said to have targeted even more people.To read this article in full or to leave a comment, please click here

IDG Contributor Network: If the cloud is so great, why are so many businesses unsatisfied?

Cloud computing has become common in enterprise IT, and the hype around it remains as adoption soars. Research by IDG shows that 70 percent of enterprises currently use at least one cloud application, and in 2018, organizations with cloud-only IT infrastructure will become the majority.The global market for cloud services was worth $148 billion in 2016, according to Synergy Research Group, and it is growing by 25 percent annually. Amazon Web Services (AWS) alone reached $3.23 billion in revenue in the third quarter of 2016, while Microsoft Azure, the second-largest cloud provider, announced Thursday that revenue has nearly doubled in the past year, giving it an annual run rate of $14 billion.To read this article in full or to leave a comment, please click here

We all know employee productivity is essential for driving revenue, but the U.S. Department of Labor reported in August that labor productivity growth in the non-farm business sector is lower now than during any of the previous 10 business cycles.To read this article in full or to leave a comment, please click here

Cisco amps-up Tetration platform with better security, reduced footprint, AWS cloud option

Cisco has rolled out a second release of its Tetration Analytics package with features such as a smaller footprint and a cloud service that will go a long way toward making the system alluring to more data center customers.Announced in June of last year, Cisco’s Tetration Analytics is a turnkey analytics package that gathers information from hardware and software sensors and analyzes the information using big data and machine learning.Tetration software sensors support Linux and Windows server hosts, while hardware sensors are embedded in Cisco network switch ASICS: Nexus 9200, Nexus 9300-EX and Nexus 9500-EX, to collect flow data at line rate from all the ports. Per Cisco once in place, the Tetration platform learns its enterprise environment and any policies IT has in place. From there it can learn which applications are dependent on each other throughout their data center and into the cloud. It can monitor server behavior patterns and group servers more efficiently.To read this article in full or to leave a comment, please click here

Facing visa issues, Indian outsourcers have strength in numbers

Indian outsourcing companies deliver services ranging from software coding to running business processes for customers in the U.S., Europe and other countries by taking advantage of low-cost, highly-skilled staff on their home turf.These companies also sometimes send people to deliver services onsite to customers.This time-tested model, backed by state-of-the-art facilities in India, could now be challenged by President Donald Trump's plan to bring jobs back to the U.S. North America accounted for 62 percent of fourth quarter revenue for Infosys, one of India’s key outsourcers. + ALSO ON NETWORK WORLD 5 tech battles facing Trump +To read this article in full or to leave a comment, please click here
