Seems the Wi-Fi Alliance is having yet another crack at coming up with a really secure protocol, this time to be called WPA3 <http://www.theregister.co.uk/2018/01/09/wi_fi_wpa3/>. Does anybody care? Remember that on the Internet, security is implemented between the endpoints, the protocols are designed not to care that everything in-between might be pawed through by eavesdroppers, or even active attackers trying to inject fake data.

Microsoft Fixes Notepad

by Lawrence D'Oliveiro

Windows Notepad has never been able to handle any newline convention other than the old DOS/Windows/CP/M one (CR-LF). Now, after so many decades, Microsoft has finally decided to give it “universal newline” capability, so it can handle lines ending in LF-only (Unix/Linux) and CR-only (old MacOS) <http://www.theregister.co.uk/2018/05/08/windows_notepad_unix_macos_line_end…>. Gee, I wonder how many lines of code that took...

Aussie Law >> Maths

by Lawrence D'Oliveiro

"The laws of Australia prevail in Australia, I can assure you of that," [Malcolm Turnbull] said on Friday. "The laws of mathematics are very commendable, but the only law that applies in Australia is the law of Australia." <https://www.techdirt.com/articles/20170714/10385237789/aussie-prime-ministe…>

Wellywood’s Digital Edge Has Dulled

by Lawrence D'Oliveiro

You may have seen an item in the news lately about a report into the large amount of subsidies that the Government puts into the local film industry. This latest report says that these subsidies pay off in jobs and revenue elsewhere, but independent reviewers question this, saying such conclusions are very sensitive to initial assumptions <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=120795…>. This extract from one of the linked documents caught my eye: Weta Digital executives ... considered that 10 years ago they were at the forefront of technology and that studios were forced to use them to achieve particular effects, they said that this is no longer true: “the degrees of difference in technology are almost imperceptible”. It is no longer technical capability that wins work, it is price point; they consider themselves a price taker. “If the grant were to disappear tomorrow it would call into question the business itself…the subsidy allows us to compete.” There is “no scenario” where the US studios would pay 20% more for Weta Digital than its competitors. VFX have long been a commodity; it’s actually surprising that Weta Digital has managed to last this long, compared to, say, Rhythm & Hues, which went bust shortly after winning an Oscar for “Life Of Pi” <http://www.fresnobee.com/news/nation-world/national/article128729769.html>. I guess it’s all down to those Government subsidies...

sudo Or su?

by Lawrence D'Oliveiro

Found this piece <https://www.pclinuxos.com/forum/index.php/topic,90479.0.html> in the PCLinuxOS forums, courtesy of a reader link from <https://www.theregister.co.uk/2018/08/01/ncsc_ubuntu/>. Basically it says that “sudo”, when used “In The Manner Of the Buntus”, i.e. to be able to run arbitrary commands as root, is a bad idea. Instead, it should be carefully restricted to allow access only to functions needed by a particular user. To get blanket root access, it is better to use “su”, which means having a separate root password. Actually, it goes further than that: it decrees that anybody posting instructions on the PCLinuxOS forums involving “irresponsible” use of sudo (i.e. contrary to the philosophy above) is subject to having their posts deleted, being reprimanded, and ultimately having their account cancelled altogether. Thoughts?

If You Buy Something, Do You Own It?

by Lawrence D'Oliveiro

Raglan man Niall Darwin discovers that assurances by electric-car company Tesla’s own official representatives aren’t worth a darn. And so, the question needs to be asked for the hundredth or thousandth time: when you buy a consumer item with essential proprietary software at its heart, what actually do you own? <https://www.newshub.co.nz/home/new-zealand/2018/07/waikato-man-suing-tesla-…>

Now They Need To Fix The TV Sets ...

by Lawrence D'Oliveiro

YouTube has adopted a more responsive page layout to cope with videos having different aspect ratios <https://arstechnica.com/gadgets/2018/07/youtube-picks-up-dark-mode-on-andro…>. To no-one’s surprise, this has annoyed a few people who have become accustomed to the old design. When 16:9 widescreen TVs were being conceived way back in the 1990s, the aim clearly was to allow us all to view cinematic movies full-screen, making maximum use of available screen area with minimal or no black bars. Nobody foresaw the widespread popularity of smartphones with built-in cameras, and of the common use of footage captured with such devices in TV broadcasts. But while such phones commonly have 16:9 screens and their cameras capture 16:9 footage, their users often hold them vertically, so the image ends up in just about the worst shape for display on a regular widescreen TV. There seems to be a common convention nowadays of filling in the gaps with blurred portions of the actual image -- which I agree looks less jarring than black bars. Hmmm ... there have been computer monitors that can be rotated to portrait or landscape orientations, with automatic adjustment of the display to match (aka “xrandr” <https://wiki.archlinux.org/index.php/xrandr>). Wouldn’t it be useful if a TV could do the same...?

Ubuntu 18.04.01 now released for most flavours

by Ian Stewart

Hi, A few days ago Ubuntu 18.04.01 was released for most flavours (e.g. Desktop, Server, Mate, Budgie, Kylin, Xubuntu, Kubuntu) You can get your flavour, in 32 or 64 bit, from here... https://www.ubuntu.com/download/desktop <https://www.ubuntu.com/download/desktop> http://cdimage.ubuntu.com/ubuntu/releases/18.04.1/release/ <http://cdimage.ubuntu.com/ubuntu/releases/18.04.1/release/> http://cdimage.ubuntu.com/ubuntu-mate/releases/18.04.1/release/ http://cdimage.ubuntu.com/ubuntu-budgie/releases/18.04.1/release/ http://cdimage.ubuntu.com/ubuntukylin/releases/18.04.1/release/ http://cdimage.ubuntu.com/xubuntu/releases/18.04.1/release/ http://cdimage.ubuntu.com/kubuntu/releases/18.04.1/release/ My understanding is that if you are running 16.04.xx LTS and you have enabled "Notify me of a new updated version of Ubuntu", then you should now start to get pop-up's prompting you to do an on-line update to 18.04.01. I'm hopeful that it will bring some stability to Mate that seemed to be lacking in 18.04.00. cheers, Ian.
