Turning Off Wi-Fi and Bluetooth in iOS 11's Control Center Doesn’t Actually Turn Off Wi-Fi or Bluetooth - Motherboard
"in iOS 11 and later, when you toggle the Wi-Fi or Bluetooth buttons in Control Center, your device will immediately disconnect from Wi-Fi and Bluetooth accessories. Both Wi-Fi and Bluetooth will continue to be available." That is because Apple wants the iPhone to be able to continue using AirDrop, AirPlay, Apple Pencil, Apple Watch, Location Services, and other features, according to the documentation.

4 Wi-Fi Tips from Former Apple Wi-Fi Engineer
Good tips: use the same SSID for all radios; deal with congestion with more APs using less power; don't use "Wide" channels on 2.4Ghz; and place antennae perpendicular to each other.

SmartThings Presence Detection using DD-WRT Router Script

Did you know that Dublin Airport is recording your phone's data? - Newstalk
Ugh. Queue tracking using secret MAC address tracking in Dublin Airport:
"I think the fundamental issue is one of consent. Dublin Airport have been tracking individual MAC addresses since 2012 and there doesn't appear to be anywhere in the airport where they warn passengers that this is this occurring. "If they have to signpost CCTV, then mobile phone tracking should at a very minimum be sign-posted for passengers," he continues.


And how long are MAC addresses retained for, I wonder?

Nelson recommends Ubiquiti
'The key thing about Ubiquiti gear is the high quality radios and antennas. It just seems much more reliable than most consumer WiFi gear. Their airOS firmware is good too, it’s a bit complicated to set up but very capable and flexible. And in addition to normal 802.11n or 802.11ac they also have an optional proprietary TDMA protocol called airMax that’s designed for serving several long haul links from a single basestation. They’re mostly marketing to business customers but the equipment is sold retail and well documented for ordinary nerds to figure out.'

Meet the e-voting machine so easy to hack, it will take your breath away | Ars Technica
The AVS WinVote system -- mind-bogglingly shitty security.
If an election was held using the AVS WinVote, and it wasn’t hacked, it was only because no one tried. The vulnerabilities were so severe, and so trivial to exploit, that anyone with even a modicum of training could have succeeded. They didn’t need to be in the polling place—within a few hundred feet (e.g., in the parking lot) is easy, and within a half mile with a rudimentary antenna built using a Pringles can. Further, there are no logs or other records that would indicate if such a thing ever happened, so if an election was hacked any time in the past, we will never know. I’ve been in the security field for 30 years, and it takes a lot to surprise me. But the VITA report really shocked me—as bad as I thought the problems were likely to be, VITA’s five-page report showed that they were far worse. And the WinVote system was so fragile that it hardly took any effort. While the report does not state how much effort went into the investigation, my estimation based on the description is that it was less than a person week.

Actually, Mr. Waxman, Consumers Are Sued For Patent Infringement All the Time | Electronic Frontier Foundation
Patent trolls have sued or threatened to sue tens of thousands of end-users. For example, Innovatio attacked cafes, bakeries, and even a funeral parlor for using off-the-shelf Wi-Fi routers. And the notorious scanner troll, MPHJ, targeted small businesses and nonprofits around the country for using ordinary office equipment. As a recent paper explained: “Mass suits against technology customers have become too common, involving building block technologies like wi-fi, scanning, email and website technologies.”

The growth in patent suits against customers reveals the importance of the Limelight case. A ruling that made it even easier to sue customers (by allowing suits against someone who performs just some steps of a patent) would encourage patent trolls to launch more abusive litigation campaigns. We hope the Supreme Court will restore the sensible rule that only a single entity (or its agents) can infringe a patent.

Russia: Hidden chips 'launch malware attacks from irons'
Cyber criminals are planting chips in electric irons and kettles to launch spam [jm: actually, malware] attacks, reports in Russia suggest. State-owned channel Rossiya 24 even showed footage of a technician opening up an iron included in a batch of Chinese imports to find a "spy chip" with what he called "a little microphone". Its correspondent said the hidden devices were mostly being used to spread viruses, by connecting to any computer within a 200m (656ft) radius which were using unprotected Wi-Fi networks. Other products found to have rogue components reportedly included mobile phones and car dashboard cameras.

Rhizome | Occupy.here: A tiny, self-contained darknet
Occupy.here began two years ago as an experiment for the encampment at Zuccotti Park. It was a wifi router hacked to run OpenWrt Linux (an operating system mostly used for computer networking) and a small "captive portal" website. When users joined the wifi network and attempted to load any URL, they were redirected to http://occupy.here. The web software offered up a simple BBS-style message board providing its users with a space to share messages and files.


Nifty project from Dan Phiffer.

Why wireless mesh networks won't save us from censorship
I'm not saying mesh networks don't work ever; the people in the wireless mesh community I've met are all great people doing fantastic work. What I am saying is that unplanned wireless mesh networks never work at scale. I think it's a great problem to think about, but in terms of actual allocation of time and resources I think there are other, more fruitful avenues of action to fight Internet censorship.

London orders rubbish bins to stop collecting smartphone data
Good call.
AUTHORITIES IN LONDON’S financial district have ordered a company using high-tech rubbish bins to collect smartphone data from passers-by to cease its activities, and referred the firm to the privacy watchdog. The City of London Corporation, which manages the so-called “Square Mile” around St Paul’s Cathedral, said such data collection “needs to stop” until there could be a public debate about it.

ICO’s Tame Investigation Of Google Street View Data Slurping
“People will yet again be asking whether Google has been let off without the kind of full and rigorous investigation that you would expect after this kind of incident,” Nick Pickles, director of the Big Brother Watch, told TechWeekEurope. “Let’s not forget that information was collected without permission from thousands of people’s Wi-Fi networks, in a way that if an individual had done so they would have almost certainly have been prosecuted. It seems strange that ICO [the UK's Data Protection regulatory agency] did not want to inspect the [datacenter] cages housing the data, while it is also troubling that Google’s assurances were taken at face value, despite this not being the first incident where consumers have seen their privacy violated by the company.”

IOS TCP wifi optimizer
Basically, tweaking a few suboptimal sysctls to optimize for 802.11b/n; requires a Jailbroken IOS device. I'm surprised that Apple defaulted segment size to 512 to be honest, and disabling delayed ACKs sounds like it might be useful (see also http://www.stuartcheshire.org/papers/NagleDelayedAck/).
TCP optimizer modifies a few settings inside iOS, including increasing the TCP receive buffer from 131072 to 292000, disabling TCP delayed ACK’s, allowing a maximum of 16 un-ACK’d packets instead of 8 and set the default packet size to 1460 instead of 512. These changes won’t only speed up your YouTube videos, they’ll also improve your internet connection’s performance overall, including Wi-Fi network connectivity.

Apple rips off student's rejected iPhone app
'Wi-Fi Sync' was rejected from the App Store last May -- and a year later, iOS 5 is released with the same feature. what a coincidence! 'Hughes said Wi-Fi Sync was rejected from the iTunes App Store in May, 2010, one month after he submitted it. He said an iPhone developer relations representative named Steve Rea personally called him prior to sending a formal rejection email to say the app was admirable, but went on to explain there were unspecified security concerns and that it did things not specified in the official iPhone software developers' kit. “They did say that the iPhone engineering team had looked at it and were impressed,” Hughes told El Reg. “They asked for my CV as well.”'

TomatoUSB
'an alternative Linux-based firmware for powering Broadcom-based ethernet routers. It is a modification of the famous Tomato firmware, with additional built-in support for USB port, wireless-N mode support, support for several newer router models, and various enhancements. Tomato USB supports many Broadcom-based routers from Asus, Linksys, Buffalo, Netgear and other manufacturers.' Looks good -- I've been a Tomato fan for many years -- and jzawodny-approved
