“Regulatory 'certainty' a must to attract Asian investors to Australia: Huawei chairman”:

See the iTWire article by Peter Dinham | Thursday, 19 September 2019 11:38.

Huawei Australia chairman John Lord says that Australia cannot turn its back on Asia's fast growing technological innovation, but warned that potential technology partners in Asia want regulatory certainty from Australia if they are to invest in the country.

Describing Asia as the global powerhouse for technological innovation, Lord said if these potential partners are going to invest and engage in the country in the longer-term there also had to be better trust between Australia and the region.

The Huawei chairman made his comments when delivering the Charles Todd Oration (CTO) to the Telecommunications Association (TELSOC) in Sydney.

On potential Asian investment in Australia, Lord said, "It hardly needs to be said that what we are seeing [in Australia] at the moment from an Asian perspective is exactly the opposite to the kind of business environment that we need to see."

"The number one thing we need to see established between Australia and the new emerging companies from Asia is trust. It is critically important."

And Lord said that Australians also needed to start changing the way they saw Asia.

"The fact is that Asia is no longer simply about mass producing cheap consumer goods, it is now moving to a different plane and is producing cutting-edge technology across a range of fields. As a country it is critically important that we understand that," he said.

The Huawei chief also said Australia "had to get it right" when dealing with the technological revolution taking place in its backyard.

"Australia is a country of between 25 million and 30 million people located at the bottom of the world — it needs to have access to and to use all of the leading innovation and technology being produced globally," he said.

“Latest Win10 Update May Break Internet Connectivity”:

See the Infopackets article by John Lister on September, 17 2019 at 01:09PM EDT.

Users have highlighted two more problems with the latest Windows 10 Update, released September 10, 2019. It's messed up sound for some users, while others can no longer get online.

For those keeping track, the problems are with the Windows 10 update KB4515384, which has already given some users a broken Windows search tool and others a mysterious red or orange hue to their screen. Ironically, that update was designed partly to fix problems with a previous update (KB4512941) which broke the Windows Search for some users, and also caused constant high processor demand for others.

One of the newly-reported problems has already been acknowledged by Microsoft. It says its had reports that "audio in certain games is quieter or different than expected after installing this update."

Multi-Channel Audio Problematic

The problem is with how Windows decides whether to play multi-channel audio such as surround sound. Microsoft says that for the moment, affected users should disable multi-channel audio in affected games as well as in any entries for third-party audio devices in Control Panel. Microsoft says it's working on a fix that's expected later this month. (Source: microsoft.com)

Microsoft hasn't yet publicly commented on reports on several feedback forums by users who have found their Ethernet and WiFi adapters no longer working, meaning they don't have any way to connect to the Internet, or their local network for that matter.

Exactly what's gone wrong remains unclear, though it appears Windows has unintentionally "hidden" the relevant devices in its Device Manager tool.

Recovery Point is One 'Solution'

In such cases, uninstalling and reinstalling the relevant drivers before rebooting the computer is usually the best first step. However, several people making the reports say that hasn't solved the problem. (Source: techradar.com)

Instead the only things that have worked for them are uninstalling the latest Windows Update or using the Recovery Point feature to restore the computer to a point before the update, which would then achieve the same outcome.

“How to Enable a Play/Pause Button on Chrome's Toolbar”:

See the How-To Geek article by CHRIS HOFFMAN | @chrisbhoffman | SEPTEMBER 11, 2019, 6:40AM EDT.

Which tab is playing sound? With Chrome's new Play/Pause button, you don't have to hunt it down. You can control playback from any browser tab using a convenient button on Chrome's toolbar.

Google Chrome's new media playback controls are part of the stable version of Chrome 77 but disabled by default. You can enable the button with a hidden flag and use it today, just like Chrome's new Extensions menu, hidden Reader Mode, and the "Send Tab to Self" feature.

Like those other options, this feature is hidden behind an experimental flag. Google may change how it works or remove it in the future. However, we expect Google to enable the Play/Pause button for everyone in a future version of Chrome.

To find this option, type chrome://flags/ into Chrome's Omnibox (address bar) and press Enter. Search for "Global Media" here. You can also copy-paste the following line into Chrome's Omnibox to go straight to this option:


Click the box to the right of Global Media Controls and select "Enabled."

Chrome will prompt you to restart your browser. Click "Relaunch Now" when you're ready, but be sure to save your work in any open tabs first. Chrome will reopen any tabs you had open after it restarts, but the current state of the tabs — for example, data you've typed in text boxes — will be lost.

Fun Facts:

“Click or Hover?”:

After some research, there does seem to be a solution to the non-availability of hover for mobile or touch devices. In 2014 the W3C Committee (who set the rules for HTML) came up with a way to click to reveal details on a web page.

That method uses the <details> tag. Inside is a <summary> tag showing the summary of a paragraph, say. When clicked, the rest of the <details> text would be revealed.

Something like this:

    Click for more detail
  <p>Here is the extra detail...</p>

Try it:

Click for more detail

This should work in browsers written since October 2014. Email clients (like Thunderbird, for example) may or may not comply with this HTML 5.1 standard, whether on laptops, Desktops or mobile devices.

We might actually be able to combine the Click and Hover methods with luck when we need to reveal some secret information.

“The Mathematics of "what3words"”:

What is what3words?

what3words is a really simple way to talk about location.

We have assigned each 3m square in the world a unique 3 word address that will never change.

For example ///filled.count.soap marks the exact entrance to what3words' London headquarters.

3 word addresses are easy to say and share, and are as accurate as GPS coordinates.”

Let's see what numbers are involved.

The area of the Earth

First, let's calculate the area of the Earth and find how many 3m squares there are:

The Earth's Radius is 6371 Km. The area is 4πR2 or 4 × π × 6,371,000 × 6,371,000 square metres.

We're getting into BIG numbers now. That comes to 510,­064,471,­909,788 square metres (or 510 trillion square metres).

The number of 3m squares

Divide that by 9 to find the number of 3m squares on the Earth.

That comes to 56,­673,830,­212,198 squares.

With a 3-word code to find every one of those squares, we need the cube-root of this number to find the total number of words required.

That's 38,411. Not so large after all!

Let's just check that: 38,411 × 38,411 × 38,411 gives: 56,­671,778,­420,531 (just under the number of squares).

And 38,412 × 38,412 × 38412 gives: 56,­676,204,­750,528 (just over).

Looks pretty good. But what if they used all the words in the Oxford English Dictionary instead?

The total number of English words

How many is that?

According to Lexico: The Second Edition of the 20-volume Oxford English Dictionary, published in 1989, contains full entries for 171,476 words in current use, and 47,156 obsolete words.

Using 171,476 current words, gives a ratio of 4.4642420140064044153 to the number of words (38,411) in use by what3words. This means that the unit area could go down by a factor of this ratio cubed. [ You are checking this with your Calculator app, we hope — Ed. ]

This ratio cubed is 88.9699181826193513235 which means that the unit area will now be 9 square metres divided by that number, or 0.1011577866299329468 square metres.

We're nearly there.

Just a matter of finding the square root of this number and we'll find the length of the edge of the new smaller unit area. And that number is 0.318053119195415134 metres. That's about 32 cm (or about one foot in the old money).

A one foot square grid?

Yes, we could divide the Earth up into 1 foot squares if we really wanted to. Unfortunately, on a web page that might look pretty dense.

So, their 3m square unit is probably a good choice after all.
