Shocked, I tell you. BT to write off £530m over 'improper' Italian accounts practices
Tuesday, 24 January 2017 19:27

BT is to write off £530m following an accounting scandal in its Italian business, saying it was "deeply disappointed" with the improper practices uncovered.

The firm had previously expected the sum to be £145m, but has today revised that figure upwards after the investigation began last October.

BT said the behaviour in its Italian business "is an extremely serious matter" and has taken immediate steps to strengthen the financial processes and controls in that business.

BT has suspended a number of BT Italy's senior management team, who have now left the business, and appointed a new chief exec of BT

Boffins explain why it takes your Wi-Fi so long to connect
Tuesday, 24 January 2017 12:29

You'd think by now that Wi-Fi has been around so long, nobody could get it wrong, right?

Wrong, according to Changhua Pei of Tsinghua University and collaborators from Tencent and the Tsinghua National Laboratory for Information Science and Technology: Wi-Fi implementations vary so much that 45 per cent of attempted connections fail, even if all you see is a frustratingly slow connection.

That quite surprising number comes from a study of the kind of scale that happens so easily in China: five million users in four cities, connecting to seven million access points and starting off 400 million Wi-Fi sessions.

Happy Monday, Juniper admins: Get patching
Monday, 23 January 2017 10:59

Juniper Networks pushed out patches for its Junos operating system over the weekend.

The first, rated high severity, is CVE-2017-2302 . It's a denial-of-service (DoS) bug in its routing protocol daemon.

“On Junos OS devices where the BGP add-path feature is enabled with 'send' option or with both 'send' and 'receive' options, a network based attacker can cause the Junos OS rpd daemon to crash and restart. Repeated crashes of the rpd daemon can result in an extended denial of service condition,” the advisory says.

It only affects devices that have the BGP add-path feature, or which have add-path configured

Boffins ready to demo 1.44 petabit-per-second fibre cables
Monday, 23 January 2017 10:05

Today's international optical systems carry impressive quantities of data, but as 'net traffic continues to grow they'll likely run out of capacity.

That's had boffins working on ways to pack more spatial paths inside the fibres, so if you were laying a twelve-pair cable across the Atlantic, you'd get multiple paths per fibre.

The research arm of Japanese network operator NTT is getting ready to demonstrate a system that can put 12 cores in a single 125 micron fibre, according to this announcement at The Optical Society.

That would, in a hypothetical deployment, yield an impressive throughput: 144 cores, and

ESP32 Tutorials
Friday, 03 March 2017 00:00

The ESP8266 has become one of those ubiquitous parts that everyone knows. However, the new ESP32 has a lot of great new features, too. If you want to take the ESP32 for a spin, you should check out [Neil Kolban’s] video series about the device. When we say series, we aren’t kidding. At last count, there were nineteen videos. Some are only a few minutes long, but some weigh in at nearly twenty minutes and the average is somewhere in between.

The topics range from setting up tools and using Eclipse and GDB. There are also tutorials on specific tasks …read more

Create Cheap Philips Hue Compatible Devices
Thursday, 02 March 2017 13:00

The Philips Hue range is a great way to add wirelessly controllable lighting to your home, but the protocol is proprietary which makes it difficult to add our own custom hardware. [Peter] found a way to create his own Hue compatible devices based on cheap JN5168 modules that are able to connect to the Hue bridge. This means you can roll out your own lamps using cheap RGB or White LEDs, a power supply and the JN5168 Zigbee Light Link module.

He started off by trying to clone a Zigbee Light Link device to a MeshBee — Seeed studio’s open …read more
