Sydney Harbour

Hello and Welcome,

Zoom News:

How do you find who is currently speaking?

In Zoom, when you have the tiled view, the speaker is ringed with a yellow border, and of course, the picture has the person's name in it.

When someone is sharing the screen, you can have all the people's pictures down the right-hand side, but you can select the "-" at the top of the list.

This screen-shot shows a single line with the name(s) of the current speaker(s), like this: [ Steve and Alex speaking at once. ]

Showing a single line showing who is currently speaking
Here are the name(s) of the current Zoom speaker(s).

Otherwise, click the thicker block dash line and you get one picture, and that's the speaker (with name in it), like this: [ This time it's Bill. ]

Showing the picture of the single current speaker
The current Zoom speaker.

So, there are ways to do what you want!

“STOP PRESS: Windows 10 2004: We're already looking into these ten issues, says Microsoft”:

See the ZDNet article by Liam Tung | 28 May 2020 — 13:05 GMT (23:05 AEST) | Topic: Enterprise Software.

Despite extra testing of the Windows 10 May 2020 update, the rollout has already thrown up multiple driver problems.

Microsoft only began rolling out the Windows 10 May 2020 Update, version 2004, to mainstream users yesterday, but the company is already investigating multiple issues.

So far, Microsoft has listed ten open investigations into a range of bugs affecting peripherals, Bluetooth, mouse input, and GPU driver and display issues.

DON'T hit the "Check for updates" button. You'll become a "seeker", i.e. "guinea-pig" for Microsoft's software testing — Ed.

“Win10 KB4556799 Breaks the Internet, Audio; Blue Screens”:

See the Infopackets article by John Lister on 27 May 2020 at 01:05 pm EDT.

Continuing what's almost become a tradition, the latest Windows 10 update has brought a string of reported problems. Microsoft says it is unclear how widespread many of them are, but has confirmed some users can no longer get online.

The confirmation comes on Microsoft's support page for the update, which has the reference number KB4556799. The Internet connectivity problem is with users who have a wireless wide area network (WWAN) LTE modem. Mainly: anyone that uses mobile broadband for Internet might be affected.

To make things worse, Microsoft says the notification area on the Windows 10 desktop may still report the computer is online even when the bug means it isn't.

Since most users use either a direct-wired connection (ethernet) or a wireless Internet connection (WiFi), the issue should affect a small number of users.

Internet Connection Fix Coming

Microsoft says it is "working on a resolution and will provide an update in an upcoming release", which raises the obvious problem that affected users might not be able to download, said the release. (Source: microsoft.com)

The other entry in the list of known issues is somewhat vague. Microsoft acknowledges that "[they] have seen social media and news reports related to various issues with KB4556799." Although there's all manner of complaints online, Microsoft says neither its official customer feedback system nor its remote monitoring of computers has shown any of these issues are widespread.

It went on to say that Microsoft will monitor the situation closely.

BSOD Back On The Scene

Among the reported problems are computers getting the dreaded "Blue Screen of Death" crash. Hewlett Packard (HP) has issued its update to fix that problem on affected machines.

Other reports include a loss of audio, slow startups, problems starting applications and glitches with games. As is becoming all-too-familiar, it seems that in many cases the problem is drivers that are no longer compatible with Windows 10 after the update. (Source: bleepingcomputer.com)

Further problems reported online include default fonts changing, portable devices switching from standard Windows 10 to Windows S mode, and searching issues in Outlook.

The only thing I am not OK with is the lack of care Microsoft seems to have for its Customers. All the issues are one thing. But Security should always be a Top Priority. If there is a security vulnerability, then that needs to be dealt with on the spot.

I can live with some minor issues and end up figuring out how to fix them myself until Microsoft puts out its next set of monthly updates. But Security Patches need to come out instantly.

“Use English (Australia) for Spell-Checking in Thunderbird”:

Find the English (Australia) dictionary for Thunderbird
This screen-shot shows how to find the English (Australia) dictionary for spell-checking in Thunderbird.

To use the English (Australia) dictionary, click on Tools > Options > Composition > Spelling, and finally, "Download More Dictionaries".

When you select the desired dictionary, Thunderbird adds it like an extension to a browser.

Don't forget to tick "Check spelling before sending" and "Enable spell check as you type".

Now, when you compose an e-mail, it will accept "dialogue" and reject "dialog", unlike the default behaviour when no dictionary is selected; using the US spellings.

“Here's Where Windows 10 Stores Its Default Wallpapers”:

See the How-To Geek article by BENJ EDWARDS | @benjedwards | 24 MAY 2020, 8:30 am EDT.

Windows 10 includes a nice selection of default wallpapers, but it's easy to lose track of them if you decide to use custom wallpaper. If you'd like to use the default images again, here's how to find and use them.

The Case of the Hidden Wallpapers

Here's the problem: in new installations of Windows, the wallpaper selection in Settings > Personalization > Background points to the default wallpaper files. At that point, you can easily change between them by using the Browse feature.

But, if you decide to use a series of your wallpapers stored in a custom location and you come back later to change the wallpaper, the defaults will have been pushed out of the five most recent images shown as thumbnails in Settings. Even worse, Windows will not remember where the default wallpaper files were stored when you click "Browse." You'll need to find them again.

How to Locate and Use Windows 10's Default Wallpapers

Windows 10 stores the default desktop wallpapers in C:\Windows\Web. This folder usually contains subfolders named after different wallpaper themes (such as "Flowers" or "Windows") or resolutions ("4K").

If you've lost track of this folder in Windows Settings, here's how to get it back. First, open Windows Settings and navigate to Personalization > Background. Just below the section that says "Choose Your Picture," click on the "Browse" button.

An open dialogue will pop up. Type C:\Windows\Web into the address bar at the top and hit enter. You can also browse to this folder from the C: drive.

The folder shown in the open dialogue will change. You can then navigate through the subfolders to pick the image you'd like to use as your desktop background. Then select the file and click "Choose Picture."

If you'd like, you can also open File Explorer and navigate to C:\Windows\Web, then copy the default image files to a better location — such as the Pictures folder in your User account. You can then find the wallpapers more easily in the future.

Were you looking for the original wallpaper that came with Windows 10 instead of the night-light one? You'll have to download it from the web instead.

More Windows 10 Wallpaper Tricks

If you're a fan of beautiful wallpaper like us, you can search for cool wallpapers online, use Bing's Daily Photos as wallpaper, or even change your wallpaper based on the time of day. And if you run a multi-monitor setup, you can choose a different wallpaper for each monitor. Have fun!

“Chrome to Automatically Block Power-Hungry Ads”:

See the Infopackets article by John Lister on 22 May 2020 at 03:05 pm EDT.

Chrome is to start automatically blocking online ads that make particularly high use of computer resources. It will be a small change that Google hopes will have a big effect.

The blocking of online ads will be the second set of changes Chrome has made to the way it handles ads following alterations over the past couple of years to block "abusive" and "deceptive" ads. These include advertisements which have misleading buttons such as a "play" button that downloads a file or a "close window" button that opens new pop-up windows.

The new change will involve Chrome having a limit on how much resources such as processing power an ad can consume before the user actively interacts with it, for example, by clicking on it.

CPU and Data Could Trigger Block

If the ad reaches the threshold, a grey box will replace the ad and an error message linking to a page explaining why Google has removed it.

The ad may trigger the threshold in two ways. The first is that in any 30 seconds, the ad either uses the device's CPU for 15 seconds or attempts to download 4 megabytes of data. The second is that the ad uses the CPU for a total of 60 seconds.

Google's initial testing found that just 0.1 per cent of all ads will breach the threshold, but that they are responsible for 27 per cent of all network data used by ads and 28 per cent of all CPU usage by ads. (Source: chromium.org)

Launch Scheduled For August

Google will expand the testing to all users of the "early release" versions of Chrome with a plan to roll it out to all users of the standard Chrome in late-August, which Google says will give the advertising community enough time to adjust to the changes. Google will provide advertisers and agencies with details of all ads blocked under the program. (Source: theregister.co.uk)

Critics of the plan say the threshold is too high, particularly as it applies to single ads rather than an entire page which could have multiple ads.

Fun Facts:

“A little Arithmetic Problem”:

10 x the nested square root of ten x etc.

Here we have an expression consisting of a product of infinitely many nested square roots.

We will use partial products; let's start with p0 = 101.

The next will be p1 = p0 × √10 = 101 + 1/2.

Then p2 = p1 × √(√10) = 101 + 1/2 + 1/4.

You can see that the exponent of 10 becomes the infinite geometric series (1 + 1/2 + 1/4 + 1/8 ...) with total = 1 / (1 - 1/2) = 2 by the geometric sum formula.

The value of the original expression is, therefore, 102 or 100.

To see this expression evaluated, watch the YouTube video by Presh Talwalkar.

He presents proof of this product in slightly different terms.

The video also shows other interesting nested expressions. Can you solve them before seeing the answers?
