Livid! Vivid Sydney 2021 COVID cancelled, planning underway for 2022
See the iTWire article by Alex Zaharov-Reutt Friday, 06 August 2021 at 17:42.
Fans of Vivid Sydney will be livid at the news that Vivid Sydney 2021 has been washed out by the decidedly unriveting and deathly dull COVID virus in what has been a "difficult decision" by the NSW Government.
The NSW Government reports having made the difficult decision to cancel Vivid Sydney 2021, but it says "the world's largest festival of light, music and ideas will shine brightly again in May-June 2022."
Of course, that all depends on whether or not the endless lockdowns infecting Australia are actually over by then, but, given the ongoing uncertainty of present-day 2021, we're told: "the decision has been made to cancel Vivid Sydney 2021 to minimise the impact on event attendees, partners, artists, sponsors and suppliers."
Next year's planning is underway, with Vivid Sydney to return from 27 May to 18 June 2022.
Minister for Jobs, Investment, Tourism and Western Sydney Stuart Ayres said Vivid Sydney would be a shining light for the community to look forward to next year.
Ayres said: "As we work together to contain the current outbreak and get our community vaccinated, we can all look forward to the return of major events like Vivid Sydney that bring us together in celebration."
"Vivid Sydney 2022 will shine brighter than ever — our artists and creative industries are so eager to put on a show, and we can't wait to see the Harbour City shining brightly again."
"We thank everyone who has contributed to the planning for Vivid Sydney 2021. Of course, it's incredibly disappointing to cancel for the second year, but the most responsible decision was to cancel early, giving everyone certainty and minimising impacts where possible."
"The health and safety of our community is our highest priority, which is why we're encouraging everyone to get vaccinated so we can get back to enjoying COVID-safe events again soon," Ayres rocked.
Expressions of interest for Vivid Sydney 2022 Light, Music and Ideas programs will open next week.
Windows 10 will soon aggressively block dubious downloads
See the PCWorld article by Mark Hachman, Senior Editor, PCWorld | AUG 4, 2021 11:30 am PDT.
Windows 10 will begin blocking potentially unwanted applications — bundled apps that you probably don't want — by default, Microsoft says, beginning in early August. The change was announced in a support document noted by Windows Latest.
If you download many third-party utilities, you may already have run into a potentially unwanted application (PUA), also called a potentially unwanted program (PUP). The terms most often describe a bundled piece of adware — or worse — a small additional application that slowly mines cryptocurrency in the background.
You might not even know how you got the PUA. Sometimes, the developer might add the PUA for additional revenue or a site that aggregates the utilities and provides them for download. Either way, the PUA is an app you never asked for and probably didn't want.
Microsoft is becoming slightly more aggressive in how it treats PUAs. Microsoft already offered you the capability of automatically filtering PUAs as part of the Windows 10 May 2020 Update, though it was off by default. Microsoft says, "Starting in early August 2021, we'll begin turning it on by default to make it easier for you to keep your systems performing at their best."
Filtering apps, of course, can lead to errors. After all, you might want to download a cryptominer to generate a bit of extra income or an app that distributes updates via an attached BitTorrent client that you're aware of and accept. If that's true, you can still toggle what Microsoft calls reputation-based protection on and off inside the Windows 10 Settings menu. Go to the Windows Security app via the Windows 10 Settings menu or Windows 10 search box, then to App & browser control > Reputation-based protection.
Under Potentially unwanted app blocking, you'll see two toggle options, Block apps and Block downloads. Both have similar functions. Block downloads work at the browser level, but only with Microsoft Edge. Block apps would be used to fend off apps before downloading within Chrome or another browser because Windows Defender will examine those apps only after they've been downloaded.
You'll also see a master toggle switch to turn off reputation-based protection entirely, though it's not recommended. As of this month, the reputation-based protection will be on by default.
Note that turning on Block apps or Block downloads won't block all apps or downloads, just the ones that Microsoft deems suspicious. Microsoft will quarantine any PUAs it detects and let you choose whether to go ahead and install them on your device. Microsoft is simply using what it knows about the app to let you know gently that it might not be a good idea.
Ordering Food Online from Woolies
It seems to be much safer staying at home than running the Supermarket gauntlet in these lockdown times.
Unfortunately, now, guards are checking you in at the doors.
So, I thought I'd try ordering some groceries instead of choosing takeaways.
Easy Log In
Go to Woolies' website at woolworths.com.au and Log in.
If it's your first time, you have to give a few details before choosing yet another password.
One question asks for your date of birth. If you type in "11/3/19nn", it ends with "11/31/9nn".
What? The 31st month of the 9nnth year? You have to enter '03' for March.
This year's online Census form has a pull-down list of months, proving that there are error-free ways of asking this sort of question.
After finally accepting all your details, you can now browse the catalogue, clicking items to add to the shopping trolley.
I got to about $42, but it would not let me place my order and check out.
Yes, there's a hidden condition: Orders must be $50 or over!
I didn't see that spelled out anywhere.
And it's not next-day delivery. It'll take about four days to get to you. Order on Sunday, and you'll receive your delivery next Thursday.
And finally, the delivery cost is a minimum of $13, bringing the amount to a tidy sum.
I'm sure most of you have long ago experienced the thrills of online food ordering.
One excellent feature of the Woolies setup: you can record your shopping lists.
Next time, if your orders are similar, just choose the list you want, edit the items and go straight to the checkout.
Here come the emails
Hi Robert, get your shopping off to a great start.
Spend $140 or more in a single order by Friday 31st January 2022, and we'll give you $15 off, as well as free Delivery*# [ See the small print at the bottom of the email — Ed. ].
Remember to use this promo code during checkout: 15*****4.
Are we surprised to be so quickly on their mailing list?
Answer to Last Week's Algebra Challenge
If you have a cubic equation, you can always put it into the form: (x - a)(x - b)(x - c) = 0 where a, b and c are the solutions.
This expression expands to x3 - (a + b + c)x2 + (ab + ac + bc)x - abc = 0.
The sum of the solutions (a + b + c) is equal to the negative of the coefficient of x2.
Last week we were looking for the sum of solutions of a cubic equation.
The equation we used for sin(10°) was:
1/2 = 3x - 4x3 ...... (1)
But we want an equation where the solutions are 1/x2 instead.
If we set y = 1/x2, we get: x = y-1/2, so we just have to put this x value into equation (1).
First, multiplying both sides of (1) by 2x-3 gives:
x-3 = 6x-2 - 8.
Substituting x = y-1/2 gives:
y3/2 = 6y - 8
And, squaring both sides gives the cubic equation:
y3 = 36y2 - 96y + 64
Finally, the polynomial equation becomes:
y3 - 36y2 + 96y - 64 = 0 ...... (2)
The coefficient of y2 in (2) is -36, proving last week's sum to be exactly 36.
