A Google engineer has published a detailed exposé on how Microsoft Windows handles file and directory pathnames (as opposed to how it is documented to handle them) <http://googleprojectzero.blogspot.com/2016/02/the-definitive-guide-on-win32…> (found from <http://www.theregister.co.uk/2016/03/01/windows_path_hacks/>). Most of it, it could be argued, makes some sort of sense from a backward-compatibility rationale. Except for the reserved device names (PRN, NUL, CON etc): Now if just specifying these paths explicitly was all that this process handled it would be annoying but not the end of the world. However it’s much worse. The conversion process actively tries to convert any path with the device name last, even if the path is a Drive Absolute path. To make matters even worse the device name can have arbitrary trailing characters as long the trailing characters are separated from the device by a dot or a colon. The name can then also have trailing spaces. ... Why it does the check is beyond me as it seems to serve no actual purpose. Also note the removal of trailing suffixes, which can come in handy if something is actively trying to guard against this behavior. For example, if an application was mindful and was checking for a filename that matched one of the reserved names you can just bypass that check by appending an arbitrary suffix.

Council CIO - suit required

by Ian Young

I fear no ordinary mortal could hope for a job such as this -- only for people from suitland who can spout the appropriate babble and appear to have a suitable track record in positions of such awesomeness. This is the world of the 'solutions provider' and they always provide a Windows solution. After all, why not go with what you know? And then there is the investment by many IT people in gaining industry qualifications around aspects of Microsoft technology. It would be sad to see that go to waste. It's a mindset thing. And let's not forget that for most people (aside from a minority of Appleheads) Windows is computers, or Windows is always on such computers as they use. Then there are the computer makers who still provide the industry standard, ie Windows. (Behind the scenes MS is still twisting arms there as far as I know). Perhaps this being broken down somewhat in recent times by the advent of tablets & smartphones but I think in large part real work is still done on a Windows box. Hard to see how this can ever change without some as yet unforeseen paradigm shift. So much for the business world and governmental organisations; things are perhaps a bit different in academia especially in fields such as computer science. However the desktop for most users is still always Windows so far as I have seen. Those crazy academics have to be given some choice but IT staff generally prefer to provide a standardised Windows image. Yes, it's a Windows world. Luckily Linux is still around for those who can't get with the programme. Personally I find the latest versions of desktop Windows unusable. If Windows 8 and 10 are the answer it must have been a most peculiar question imho. But I digress. Should HCC ever adopt Linux I will eat my hat - or be astounded at any rate.

A ZFS developer’s analysis of the good and bad in Apple’s new APFS file system

by Peter Reutemann

"Adam Leventhal: Apple announced a new file system that will make its way into all of its OS variants (macOS, tvOS, iOS, watchOS) in the coming years. Media coverage to this point has been mostly breathless elongations of Apple's developer documentation. With a dearth of detail I decided to attend the presentation and Q&A with the APFS team at WWDC. Dominic Giampaolo and Eric Tamura, two members of the APFS team, gave an overview to a packed room; along with other members of the team, they patiently answered questions later in the day. With those data points and some first-hand usage I wanted to provide an overview and analysis both as a user of Apple-ecosystem products and as a long-time operating system and file system developer." -- source: http://arstechnica.com/apple/2016/06/a-zfs-developers-analysis-of-the-good-… 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/

Ubuntu-Based Peppermint 7 Released

by Peter Reutemann

'Softpedia reports on the newest version of Peppermint OS, "a lightweight, stable, elegant, and fast computer operating system based on GNU/Linux and Open Source technologies." An anonymous Slashdot reader quotes their report: It's a bit earlier than expected, but the Peppermint OS 7 GNU/Linux distribution has been officially unveiled...based on the Ubuntu 16.04 LTS (Xenial Xerus) operating system [with] a lot of packages from the Ubuntu 16.04 LTS distro, which means that it will also be a long-term support release.... "Along with the shift to the 16.04 (Xenial) code base, Peppermint 7 continues our policy of choosing the best components from other desktop environments, wherever that may be, and integrating them into a cohesive whole with our own software," reads today's announcement. "Team Peppermint" says they're switching to Firefox as their default browser for site-specific browser functionality (similar to Chrome's -app mode) after Google dropped their 32-bit version of Chrome and moved to PPAPI plugins "which effectively ends Flash support in 32-bit Chromium"... But you can also still choose Chrome or Chromium for site-specific browsing (and the OS comes in 32-bit and 64-bit editions).' -- source: https://news.slashdot.org/story/16/06/25/216216 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/

KDE Developers Have Been Working On Improved Windows Support

by Lawrence D'Oliveiro

<http://phoronix.com/scan.php?page=news_item&px=KDE-Windows-Improvements>: “... they've abandoned the concept of having a single KDE installer for Windows, but work on individual programs (and installers) for Windows has continued. Single application installers are their path forward for shipping KDE programs on Windows...” Also in the reader comments, Krita lead Boudewijn Rempt writes about whether more Windows users leads to more Windows developers contributing <https://www.phoronix.com/forums/forum/software/desktop-linux/879128-kde-dev…>: “... I've certainly had half a dozen Windows developers come to the #krita irc channel asking how to build Krita on Windows so they could help out hacking. The problem is that setting up a build environment on WIndows is really hard, and in fact, we build the Windows binaries on Linux... So they need extraordinary perseverance to start contributing or use a Linux VM. That's really something we should improve on next, but I have no idea how to make it any eas[i]er anymore.”

WLUG meeting next Monday

by Peter Reutemann

Hi there We have a meeting next Monday: 'systemd', which has replaced SYSTEMV 'init' in nearly ALL current Linux distributions, seems to go against the fundamental philosophy of Linux/Unix - Doug Mcllroy, the inventor of Unix pipes, summarized the Unix/Linux philosophy as follows: "This is the Unix philosophy: Write programs that do one thing and do it well..." systemd has a 'finger-in-all-pies' approach & seems quite complex. Let's discuss pros and cons of systemd. http://www.meetup.com/WaikatoLinuxUsersGroup/events/231330392/ 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/

Linux’s RPM/deb split could be replaced by Flatpak vs. snap

by Peter Reutemann

'Linux developers are going to have more than one choice for building secure, cross-distribution applications. Ubuntu's "snap" applications recently went cross-platform, having been ported to other Linux distros including Debian, Arch, Fedora, and Gentoo. The goal is to simplify packaging of applications. Instead of building a deb package for Ubuntu and an RPM for Fedora, a developer could package the application as a snap and have it installed on just about any Linux distribution. But Linux is always about choice, and snap isn't the only contender to replace traditional packaging systems. Today, the developers of Flatpak (previously called xdg-app) announced general availability for several major Linux distributions, with a pointer to instructions for installing on Arch, Debian, Fedora, Mageia, and Ubuntu.' -- source: http://arstechnica.com/information-technology/2016/06/here-comes-flatpak-a-… 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/
