The drinks are on Juniper: Revenue and profits up in Q2 2017
Wednesday, 26 July 2017 12:58

Juniper Networks has turned in a solid second quarter, reporting growth in revenue and profitability.

Today the company reported revenue of US$1.3bn (all figures here are GAAP), and net income of $179.8m, better than Q2 2016 by a more-than-handy 28 percent.

Switching was the company's engine room for Q2, piling on 32 per cent year-on-year growth ($276 million) to offset a completely flat routing segment ($572 million).

Services added 9 per cent year-on-year to hit $392 million, but security shed 12 percent year-on-year ($69 million).

Cloud sales are booming, the company reports, piling on 32 per cent year-on-year to reach

Sysadmin Day 2017: Still time to get the beers in
Friday, 28 July 2017 21:18

It's that time of year again, dear readers: it's Sysadmin Day 2017. Today is that one day a year where employers and coworkers are expected to give a token acknowledgement of the trials and tribulations of their overworked IT staffs and usually fail to do so.

We here at The Register , however, have not forgotten you.

Today's systems administrators are an increasingly diverse lot. Many of us clawed out way up through generations of equipment; the old mainframes through to DOS and the early Macintoshes. Windows and OS/2 gave way to Windows NT and Linux. Specialties evolved ranging from

After we ran our article about the fate of .sk, the nation of Slovakia flew into a rage. And now, here's part two...
Friday, 28 July 2017 15:04

Analysis A campaign to convince the Slovakian government to halt the sale of the .sk registry has nothing to do with money or politics, it is claimed.

Earlier this month, we reported on a string of articles, speeches and open letters that alleged the country's top-level domain was effectively stolen in 1999 – and that the goal of this offensive is to prevent the sale of .sk to UK-based CentralNic.

Those behind the campaign argued the current operator – SK‑NIC – should be forced to hand over the keys to the TLD to a new, undefined non-profit operator that would

Cisco bugs leave network automation vulnerable to attack
Thursday, 27 July 2017 17:01

A slip in certificate handling is one of three bugs in Cisco's Autonomic Networking software.

As its name implies, Autonomic Networking is about reducing the load on network administrators by offering self-management for suitable switches and routers under suitable versions of the IOS operating system.

And then, as they say, the murders began: Autonomous Networking uses infrastructure certificates to verify nodes in the system, and that's where the problem has emerged.

It starts with this advisory : a mistake in infrastructure certificate revocation.

In Cisco IOS XE, the bug could let an unauthenticated, remote autonomic node back into a network

OpenEMS Makes Electromagnetic Field Solving… Merely Difficult
Saturday, 29 July 2017 11:30

To ordinary people electronics is electronics. However, we know that the guy you want wiring your industrial furnace isn’t the guy you want designing a CPU. Neither of those guys are likely to be the ones you want building an instrumentation amplifier. However, one of the darkest arts of the electronic sects is dealing with electromagnetic fields. Not only is it a rare specialty, but it requires a lot of high-powered math. Enter OpenEMS, a free and open electromagnetic field solver.

We would like to tell you that OpenEMS makes doing things like antenna analysis easy. But that’s like saying …read more

Rapidly Prototyping RF Filters
Thursday, 27 July 2017 01:00

RF filters are really just a handful of strategically placed inductors and capacitors. Yes, you can make a 1 GHz filter out of through-hole components, but the leads on the parts turn into inductors at those frequencies, completely ruining the expected results in a design.

The solution to this is microstrip antennas, or carefully arranged tracks and pads on a PCB. Anyone can build one of these with Eagle or KiCad, but that means waiting for an order from a board house to verify your design. [VK2SEB] has a better idea for prototyping PCB filters: use copper tape on blank …read more
