Mellanox says it ships enough ports not to need Starboard
Tuesday, 13 March 2018 15:02

The spat over activist investor Starboard Value's plan to have Mellanox sell itself or do something else to enhance its value has resumed.

Hostility between the two companies dates back to November 2017 , when Starboard criticised Mellanox for refusing advances from Marvell Semiconductor.

Starboard held 10.7 per cent of Mellanox at the time, plus a position in Marvell. At the time, the activist investor claimed Mellanox was suffering a “growing disparity” between its “margins, growth, and stock price performance compared to its peer group”.

Mellanox tried turning away that wrath with the soft answer that it “welcomes the input

Tutanota blames Comcast block for March 1 outage
Tuesday, 13 March 2018 09:08

The creator and co-founder of Tutanota is blaming Comcast after his encrypted mail service was briefly taken offline earlier this month.

Mathias Pfau claims his secure email service was mysteriously unavailable to Comcast customers for around 18 hours over a period spanning from the evening of March 1 until late in the the morning of March 2. Tutanota says the ISP has not offered any explanation for the outage.

According to Pfau, the outage was serious enough that the site received "hundreds" of complaints from Comcast customers in the US who were left unable to check their mail over the

Russia stares admiringly at itself, flexes internet muscles
Tuesday, 13 March 2018 05:52

The Russian government has again intimated that it is prepared to cut itself off from the global internet, with a presidential aide telling a Russian news network that it is "ready for anything."

Russian presidential aide on the internet, German Klimenko, took an unusual tack: he suggested that Western nations would be the ones to cut off Russia from the global network as part of broader sanctions. If that happened, he theorized, Russia was ready.

The interview with NTV was also written up by news site RT indicating that the Putin government is pushing the argument.

Klimenko then went into

CableLabs backhaul spec gets speed boost
Monday, 12 March 2018 11:59

Late last week, CableLabs launched another bandwidth-boosting project, this time designed to sweat more gigabits-per-second out of the optical leg of cable networks.

The US cable industry's research arm launched its Full Duplex Coherent Optics project, designed to double the capacity of the upstream channels from HFC nodes to the exchange.

The new work is a development on CableLabs' existing point-to-point Coherent Optics specification project, distinguished technologist Steve Jia wrote .

Coherent optics replaces simple on-off keying (OOK, as used in PON deployments) with modulation on both amplitude (amplitude shift keying, ASK) and phase (phase shift keying, PSK) to expand

Sneaky satellite launch raises risk of Gravity-style space collision
Saturday, 10 March 2018 09:03

The space-disaster movie Gravity – where an escalating wave of space debris wipes out a space station and shuttle – now looks like a slightly more plausible scenario.

The Federal Communication Commission (FCC) has pulled permission from Silicon Valley startup Swarm Technologies to launch four satellites into space after what it says was an "apparent unauthorized launch" back in January.

According to IEEE Spectrum , that unauthorized launch consisted of four experimental satellites that the FCC had decided were too small to be noticed in space – and hence pose an unacceptable risk of collision – but which the company

Ofcom to networks: Want this delicious 5G spectrum? You'll have to improve 4G coverage
Saturday, 10 March 2018 02:21

Ofcom has today proposed placing new coverage obligations on mobile operators for 4G services as part of their winning 5G spectrum bids.

All four operators have met the obligation to reach 90 per cent of the country's landmass by the end of 2017.

But the UK regulator said: "While the previous obligations have resulted in improvements, we want mobile companies to go further. We are now planning new requirements for when we release spectrum in the 700MHz band for mobile services, which we expect to auction in late 2019."

Operators will be able to increase coverage by up to 3
