Linux expr command tutorial for beginners (with examples)
by Peter Reutemann 25 Aug '17

25 Aug '17

'Sometimes, while working on the command line (especially when dealing with a shell script), you may find yourself in a situation where you have to perform actions like searching for a substring in a string, finding its index, as well as other things like performing comparisons and arithmetic operations. For those who aren't in the know, there exists a command line utility - dubbed expr - that lets you do all this. In this tutorial, we will discuss the basics of this command along with some of the features it provides.' -- source: https://www.howtoforge.com/linux-expr-command/ 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/

You Can Help Purism Build the Secure Open Source Linux-based Librem 5 Smartphone
by Peter Reutemann 24 Aug '17

24 Aug '17

'Thankfully, consumers are starting to wake up and become more aware of security and privacy, and some companies, such as Purism, are designing products to safeguard users. The company's laptops, for instance, run an open source Linux-based operating system, called "PureOS" with a focus on privacy. These machines even have hardware "kill switches" so you can physically disconnect a webcam or Wi-Fi card. Today, Purism announces that it is taking those same design philosophies and using them to build a new $599 smartphone called Librem 5. The planned phone will use the GNOME desktop environment and PureOS by default, but users can install different distros too. Sound good? Well you can help the company build it through crowdfunding. "Purism, the social purpose corporation which designs and produces popular privacy conscious hardware and software, has revealed its plans to build the world's first encrypted, open platform smartphone that will empower users to protect their digital identity in an increasingly unsafe mobile world. After 18 months of R&D to test hardware specifications and engage with one of the largest phone fabricators, Purism is opening a self-hosted crowdfunding campaign to gauge demand for the initial fabrication order and add the features most important to users," says Puris' -- source: https://linux.slashdot.org/story/17/08/24/147204 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/

Spyware backdoor prompts Google to pull 500 apps with >100m downloads
by Peter Reutemann 23 Aug '17

23 Aug '17

'At least 500 apps collectively downloaded more than 100 million times from Google's official Play Market contained a secret backdoor that allowed developers to install a range of spyware at any time, researchers said Monday. The apps contained a software development kit called Igexin, which makes it easier for apps to connect to ad networks and deliver ads that are targeted to the specific interests of end users. Once an app using a malicious version of Igexin was installed on a phone, the developer kit could update the app to include spyware at any time, with no warning. The most serious spyware installed on phones were packages that stole call histories, including the time a call was made, the number that placed the call, and whether the call went through. Other stolen data included GPS locations, lists of nearby Wi-Fi networks, and lists of installed apps.' -- source: https://arstechnica.com/information-technology/2017/08/500-google-play-apps… 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/

Sky Versus The Newspapers
by Lawrence D'Oliveiro 22 Aug '17

22 Aug '17

Sky TV, in its latest annual report, is blaming its poor performance on “piracy”, specifically “the newspaper industry”. [CEO John] Fellet, in the company's annual report, said media outlets were taking clips from "the best parts" of Sky sport content and placing them on their websites without permission. Fair Dealing provisions in the Copyright Act allow news outlets to use a copyrighted work in the context of reporting current events. <http://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=11908731>

Moreutils – A Collection Of More Useful Unix Utilities
by Peter Reutemann 22 Aug '17

22 Aug '17

'We all know about GNU core utilities that comes pre-installed with all Unix-like operating systems. These are the basic file, shell and text manipulation utilities of the GNU operating system. The GNU core utilities contains the commands, such as cat, ls, rm, mkdir, rmdir, touch, tail, wc and many more, for doing the day-to-day operations. Since these commands are part of Core Utilities, you don’t have to manually install them. Among these utilities, there are also some other useful collection of Unix utilities which are not included in any Unix-like operating systems. Meet moreutilis, a growing collection of the unix tools. The moreutils can be installed on GNU/Linux, and various Unix flavours such as FreeBSD, openBSD and Mac OS.' -- source: https://www.ostechnix.com/moreutils-collection-useful-unix-utilities/ 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/

fdisk Versus parted
by Lawrence D'Oliveiro 21 Aug '17

21 Aug '17

When the first hard drives appeared that were bigger than the 2TiB limit that the MBR partition format could cope with, it seemed like the only tool available that could manage partitions in the new GPT format was GNU parted. So you had to say goodbye to the old fdisk and sfdisk utilities, and learn a new way of setting things up. Well, it turns out that the old programs have been updated with new features, and they can now cope with setting up and using GPT-partitioned disks just fine. I particularly like the “sfdisk -d” command, which dumps out the partition table in a detailed format that can be backed up and then used for restoration later, if the disk’s partition table should somehow get corrupted. As far as I could see, parted never gave the exact numbers, down to the sector, that were necessary for this. Also, in the past day, two problems with parted have manifested themselves acutely to me: * All partitioning changes are made immediately, unlike fdisk. * Also unlike fdisk, it didn’t seem to notice if you were clobbering existing partitions, and would happily overwrite them. Each of these (mis)features might seem bad enough on its own, but putting them together is a recipe for woe. So in future, I think I am going to abandon parted and go back to fdisk and sfdisk.
