Programmers’ Question Time

I think Verity Stob <https://www.theregister.co.uk/2019/05/23/verity_stob_column_may/> has outdone herself: Some people, when confronted with a problem, think “I know, I’ll use FP.” Now they have two problems... Although actually they still think they’ve got one problem, because the problem counter is now immutable.

Antergos Linux Has Been Discontinued
by Peter Reutemann 23 May '19

23 May '19

'An Arch Linux based distribution, Antergos, has been discontinued. The project's primary goal was to make Arch Linux available to a wider audience of users by providing a streamlined, user friendly experience including a safe place for users to communicate, learn, and help one another. There have been 931,439 unique downloads of Antergos Linux since 2014. The primary reason for ending support for it was that the developers no longer have enough free time to properly maintain the distribution. They came to this decision because they believe that continuing to neglect the project would be a huge disservice to the community. Taking this action now, while the project's code still works, provides an opportunity for interested developers to take what they find useful and start their own projects. For existing Antergos users: there is no need to worry about installed systems as they will continue to receive updates directly from Arch. Soon, an update will be released that will remove the Antergos repos from system along with any Antergos-specific packages that no longer serve a purpose due to the project ending. Once that is completed, any packages installed from the Antergos repo that are in the AUR will begin to receive updates from there. The Antergos Forum and Wiki will continue to be available until such time it becomes clear that users have moved on to other projec' -- source: https://linux.slashdot.org/story/19/05/23/1813214 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/

Crowdfunded Android Console Ouya Will Be Shut Down On June 25th
by Peter Reutemann 23 May '19

23 May '19

'Razer, the gaming hardware manufacturing company that purchased Ouya's software assets in mid-2015, announced today that the crowdfunded Android console will cease functioning on June 25th. "That date will mark the unremarkable end of what began as a runaway Kickstarter success story: the inexpensive Ouya mini-console was powered by Android and introduced games such as TowerFall," reports The Verge. "But despite being positioned as the indie console, Ouya never quite took off after its $8.5 million crowdfunding campaign. The goal was to move Android's indie gaming scene to TV screens -- with exclusive Ouya-only titles mixed in -- but the execution didn't pan out." From the report: The hardware has been discontinued ever since Razer acquired Ouya's software assets in 2015. So it's somewhat surprising that the platform has continued to plod along for nearly four additional years. But that all ends next month. Accounts will be deactivated on June 25th. After that, Razer says "access to the Discover section will no longer be available. Games downloaded that appear in Play may still function if they do not require a purchase validation upon launch." But by and large, games on the Ouya platform will stop working after the cutoff date. Razer notes that some developers might choose to help their Ouya customers by activating the same game on some other platform (i.e., Google Play) where available following the shutdown. Razer's own Forge TV device will continue functioning as an Android TV set-top box, but the Forge TV games store is also going offline come the 25th. Part of Razer's thinking behind the Ouya acquisition was to propel its long-term Android TV gaming ambitions. The company has clearly shifted its priorities over the last few years, as indicated by the decision to finally shut down Ouya once and for all.' -- source: https://hardware.slashdot.org/story/19/05/22/2042225 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/

ARM Memo Tells Staff To Stop Working With Huawei
by Peter Reutemann 22 May '19

22 May '19

'UK-based chip designer ARM has told staff it must suspend business with Huawei, according to internal documents obtained by the BBC. ARM instructed employees to halt "all active contracts, support entitlements, and any pending engagementsâ with Huawei and its subsidiaries to comply with a recent US trade clampdown. From a report: ARM's designs form the basis of most mobile device processors worldwide. In a company memo, it said its designs contained "US origin technology." As a consequence, it believes it is affected by the Trump administration's ban. One analyst described the move, if it became long-term, as an "insurmountable" blow to Huawei's business. He said it would greatly affect the firm's ability to develop its own chips, many of which are currently built with ARM's underlying technology, for which it pays a licence.' -- source: https://tech.slashdot.org/story/19/05/22/141215 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/

Android and iOS Devices Impacted By New Sensor Calibration Attack
by Peter Reutemann 22 May '19

22 May '19

'A new device fingerprinting technique can track Android and iOS devices across the Internet by using factory-set sensor calibration details that any app or website can obtain without special permissions. From a report: This new technique -- called a calibration fingerprinting attack, or SensorID -- works by using calibration details from gyroscope and magnetometer sensors on iOS; and calibration details from accelerometer, gyroscope, and magnetometer sensors on Android devices. According to a team of academics from the University of Cambridge in the UK, SensorID impacts iOS devices more than Android smartphones. The reason is that Apple likes to calibrate iPhone and iPad sensors on its factory line, a process that only a few Android vendors are using to improve the accuracy of their smartphones' sensors. "Our approach works by carefully analysing the data from sensors which are accessible without any special permissions to both websites and apps," the research team said in a research paper published yesterday. "Our analysis infers the per-device factory calibration data which manufacturers embed into the firmware of the smartphone to compensate for systematic manufacturing errors [in their devices' sensors]," researchers said. This calibration data can then be used as a fingerprint, producing a unique identifier that advertising or analytics firms can use to track a user as they navigate across the internet.' -- source: https://it.slashdot.org/story/19/05/22/1852204 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/

decompressing large zip files
by Peter Reutemann 22 May '19

22 May '19

Hi there Once in a while, I get large zip files from clients. Since they are running Windows, their zip tool doesn't have the same 4GB limitation that the unzip command-line tool under Linux usually has. Today, I once again had to deal with a large file and had some time to look into a solution that wouldn't involve copying the file onto a Windows box for converting the archive. If you have p7zip-full installed, you can use: 7z x file.zip If you have Java installed, you can use: jar xf file.zip Found here: https://serverfault.com/questions/235139/how-to-unzip-files-bigger-than-4gb 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/

Google Says Some G Suite User Passwords Were Stored In Plaintext Since 2005
by Peter Reutemann 21 May '19

21 May '19

'Google says a small number of its enterprise customers mistakenly had their passwords stored on its systems in plaintext. The exact number was not disclosed. "We recently notified a subset of our enterprise G Suite customers that some passwords were stored in our encrypted internal systems unhashed," said Google vice president of engineering Suzanne Frey. Slashdot reader pegdhcp appears to be one of the users impacted by this security lapse: I am sharing a message that I received from G Suite, redacted. They are having some serious problem... If you missed the message or somehow tend to ignore sometimes extremely frequent and unnecessary G Suite messages like I do, this one can be important depending on your settings.' -- source: https://it.slashdot.org/story/19/05/21/223208 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/

Huawei Considers Rivals To Google's Android After US Ban
by Peter Reutemann 21 May '19

21 May '19

'Huawei said it's working on its own operating system for its mobile handsets and will consider rivals to Google's Android, after the U.S. blacklisted the company, threatening its partnerships with chip, component and software suppliers. From a report: The Chinese telecom equipment giant said Tuesday it was in talks with the Alphabet about how to proceed after Google confirmed it would cut access to some of Huawei's operating system features for the company's new devices in response to the announcement. Should Google's system no longer be available, "then the alternative option will naturally come out -- either from Huawei or someone else," Abraham Liu, Huawei's representative to the European Union institutions, said at an event in Brussels on Tuesday. Liu said Huawei had been working on its own operating system but that he didn't have the details about when this would be ready. Huawei would do everything in its power to mitigate the impact of the U.S. decisions, Liu said' -- source: https://mobile.slashdot.org/story/19/05/21/1357240 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/

Firefox 67 Arrives With New Performance and Privacy Features, Voice Search Widget on Android
by Peter Reutemann 21 May '19

21 May '19

'Mozilla today launched Firefox 67 for Windows, Mac, Linux, and Android. From a report: The 10th release since Mozilla's big Firefox Quantum launch in November 2017 doubles down on performance and privacy. Firefox 67 includes deprioritizing least commonly used features, suspending unused tabs, faster startup, blocking of cryptomining and fingerprinting, Private Browsing improvements, voice input in the Android search widget, and more. [...] Firefox 67 is better at performing tasks at the optimal time, resulting in faster "painting" of the page. Specifically, the browser deprioritizes least commonly used features and delays set Timeout to prioritize scripts for things you need. Mozilla says Instagram, Amazon, and Google searches now execute between 40% and 80% faster. Firefox also now scans for alternative style sheets after page load and doesn't load the auto-fill module unless there is a form to complete. Next, Firefox 67 detects if your computer's memory is running low (under 400MB) and suspends unused tabs. If you do click on a tab that you haven't used or looked at in a while, it will reload where you left off. Finally, Firefox 67 promises faster startup for users that customized their browser with an add-on.' -- source: https://news.slashdot.org/story/19/05/21/1636224 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/

First Official Version of Tor Browser for Android Released on Play Store
by Peter Reutemann 21 May '19

21 May '19

'The Tor Project today made the first stable version of its privacy-focused browser available on the Google Play Store. From a report: This new mobile browser integrates the Tor protocol stack into a standalone browser and replaces Orfox as the main way to navigate the Tor network from an Android device. Tor Project developers have been working on this browser for eight months now, since September 2018, when they first released an alpha version for public testing. "We made it a priority to reach the rising number of users who only browse the web with a mobile device," said Isabela Bagueros, Executive Director of the Tor Project. "These users often face heavy surveillance and censorship online, so it is critical for us to reach them. We made sure there are no proxy bypasses, that first-party isolation is enabled to protect you from cross-site tracking, and that most of the fingerprinting defenses are working," the Tor team added.' -- source: https://yro.slashdot.org/story/19/05/21/1835256 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/
