Firefox Monitor Will Inform You of Data Breaches
by Peter Reutemann 25 Sep '18

25 Sep '18

'Earlier this year, Mozilla announced Firefox Monitor, a service that will inform you if your online accounts were hacked in a recent data breach. It's now available to general public. A report adds: For the new security-focused tool, Mozilla partnered with Troy Hunt, the renowned security expert behind Have I Been Pwned? (HIBP), which is a database of data breaches that allows anyone to discover whether one of their online accounts has been compromised. The first iteration of Firefox Monitor is, for all intents and purposes, a clone of HIBP. After you enter your email address and hit the scan button, you're told which online services have leaked your personal details (if any). You can also sign up to be notified of any future data breaches involving one or more of your email addresses.' -- source: https://tech.slashdot.org/story/18/09/25/1928234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Slack Buys and Shuts Down Intelligent Email App Astro
by Peter Reutemann 25 Sep '18

25 Sep '18

Since we discussed matrix.org at last night's meeting, this might be of interest: 'Slack has acquired email app company Astro to incorporate it into Slack channels. As a result, Astro is shutting down its Mac, iOS, Android, Alexa and Slack apps. They're no longer taking new users and existing ones will lose access on October 10th. Engadget reports: The company said that with over 50 million channels created to date, they're increasingly becoming the platform through which teams collaborate. "But we all know that email is still a very important tool in business communication," said Slack. "We've taken some steps to make it possible to integrate email into Slack, but now we're in a position to make that interoperability much simpler and much, much more powerful." Last year, Astro launched its Astrobot Slack app, which let users manage their emails and check their Office 365 or Google calendars from within Slack. It also allowed them to do one search to pull up results from both Slack and email. "As we explored with Slack how to bring together messaging, email and calendar, it became evident that we would have the biggest impact on workplace communications and realize our original vision by joining Slack," the company said.

Sky TV Wants ISPs To Block Pirate Sites
by Lawrence D'Oliveiro 25 Sep '18

25 Sep '18

From <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121313…>: Sky says ISPs should introduce blocking, because other countries do it. But it doesn’t mention how effective such blocks actually are(n’t). Also, it appears 5% of NZers have discovered the usefulness of Kodi boxes. The article nicely points out one problem with trying to block some of these “pirate” sites: Sky has also taken at least a dozen cases against individuals who accessed illegal Facebook streams of Joseph Parker fights - although it only sought token costs, not damages. However, while Sky's action over illegal Parker fight streaming has been successful, it also illustrates the complications of Sky's website blocking request. It is unlikely any ISP would want to block Facebook.

topic(s) for this month's meeting?
by Peter Reutemann 23 Sep '18

23 Sep '18

Hi everyone In all that Alexa excitement at the last meeting, I completely forgot to figure out topic/speaker for this month's meeting. Anybody keen on presenting or an interesting topic to discuss? Is actually anybody running the latest 4.19 kernel and noticed significant performance drops (thanks to specter/meltdown)?

Cloudflare Promotes The InterPlanetary File System
by Lawrence D'Oliveiro 19 Sep '18

19 Sep '18

Content-distribution company Cloudflare is trying to encourage use of the InterPlanetary File System (IPFS) as a way to do distributed hosting of static content <https://blog.cloudflare.com/distributed-web-gateway/>. Instead of using host-specific URLs to find what you want, you specify hashes for the items, and it finds them wherever they are, across all the available IPFS nodes. What Cloudflare is doing is offering an IPFS “gateway”, which means you put the hash into a URL pointing at a Cloudflare server to specify the item. That way you don’t have to set up an IPFS node yourself. Found from this news item <https://www.theregister.co.uk/2018/09/18/cloudflare_backs_interplanetary_fi…>.

Ampere’s ARM Server Shipping At Last
by Lawrence D'Oliveiro 18 Sep '18

18 Sep '18

A 32-core, 64-bit ARMv8 machine running at up to 3.3GHz in turbo mode is apparently now available <https://www.theregister.co.uk/2018/09/18/ampere_shipping/>. 125W sounds a pretty modest draw for such a grunty machine. And only a 3-figure price tag, too (OK, maybe 4 figures in NZD).

A Property Owner Can Be Forced To Trim Trees That Block Wi-Fi
by Lawrence D'Oliveiro 18 Sep '18

18 Sep '18

A recent High Court judgement <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121272…> has ruled that a neighbour can force you to trim the trees on your property if they block their wireless Internet access. The article notes that this was more of an issue with the 2.6GHz frequency being used for this connection than it might have been for the 700MHz band employed by other providers.

Amazon Plans To Release At Least 8 New Alexa-Powered Devices, Including A Microwave, Amplifier, and In-Car Gadget
by Peter Reutemann 18 Sep '18

18 Sep '18

'Amazon is planning to release at least 8 new voice-controlled hardware devices before the end of the year, according to CNBC. "The devices include, among others, a microwave oven, an amplifier, a receiver, a subwoofer, and an in-car gadget, people familiar with the matter said," reports CNBC. "All of the devices will be Alexa-enabled, meaning they can easily connect to the voice assistant. Some of the devices will also have Alexa built in." From the report: Amazon is expected to reveal some of these devices at an event later this month, according to an internal document describing the plans. The new devices reflect Amazon's ambition to make its Alexa voice technology ubiquitous by focusing on areas where people spend most of their time -- at home and in the car. Alexa was initially considered a geeky experiment at Amazon. Now it is now one of the most popular voice assistants, leading the growth of the burgeoning smart speaker market, which is expected to be worth $30 billion by 2024, according to Global Market Insights.

Vulnerability in WebKit Crashes and Restarts iPhones and iPads
by Peter Reutemann 16 Sep '18

16 Sep '18

'Catalin Cimpanu, writing for ZDNet: A security researcher has discovered a vulnerability in the WebKit rendering engine used by Safari that crashes and restarts the iOS devices -- iPhones and iPads. The vulnerability can be exploited by loading an HTML page that uses specially crafted CSS code. The CSS code isn't very complex and tries to apply a CSS effect known as backdrop-filter to a series of nested page segments (DIVs). Backdrop-filter is a relative new CSS property and works by blurring or color shifting to the area behind an element. This is a heavy processing task, and some software engineers and web developers have speculated that the rendering of this effect takes a toll on iOS' graphics processing library, eventually leading to a crash of the mobile OS altogether.

The Linux Kernel Has Grown By 225, 000 Lines of Code This Year, With Contributions From About 3, 300 Developers
by Peter Reutemann 16 Sep '18

16 Sep '18

'Here's an analysis of the Linux kernel repository that attempts to find some fresh numbers on the current kernel development trends. He writes: The kernel repository is at 782,487 commits in total from around 19.009 different authors. The repository is made up of 61,725 files and from there around 25,584,633 lines -- keep in mind there is also documentation, Kconfig build files, various helpers/utilities, etc. So far this year there has been 49,647 commits that added 2,229,836 lines of code while dropping 2,004,759 lines of code. Or a net gain of just 225,077 lines. Keep in mind there was the removal of some old CPU architectures and other code removed in kernels this year so while a lot of new functionality was added, thanks to some cleaning, the kernel didn't bloat up as much as one might have otherwise expected. In 2017 there were 80,603 commits with 3,911,061 additions and 1,385,507 deletions. Given just over one quarter to go, on a commit and line count 2018 might come in lower than the two previous years. Linus Torvalds remains the most frequent committer at just over 3% while the other top contributions to the kernel this year are the usual suspects: David S. Miller, Arnd Bergmann, Colin Ian King, Chris Wilson, and Christoph Hellwig. So far in 2018 there were commits from 3,320 different email addresses. This is actually significantly lower than in previous years.' -- source: https://linux.slashdot.org/story/18/09/16/172217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
