216/02/2023Optus won’t lock a SIM card – do other providers? – We’ll follow this up in future weeks. Providers (Telstra etc) are supposed to check identity documents. If you follow the security advice we discuss you are probably not going to have a problem.
Telstra’s approach to SIM-swapping

My computer is running slow – what can I do about it? We started with some theory on how a computer works with particular emphasis on storage. We noted that HDDs are significantly slower than SSDs. Slides from the session.
323/02/2023Cloud storage – Dropbox:
colour slides
402/03/2023Should you accept a “free upgrade” from your Telco? Telstra’s “Standard” speed is 25Mbps download and 4Mbps upload. If you are offered a free upgrade to “Standard Plus” with 50Mbps download and 17Mbps upload, then that sounds like a good deal. Check that there isn’t a time limit on “free”.

Signing and sending PDF forms – the simplest way is to print the document, sign it and then scan it with your phone to send it. Apple Notes app includes a scanner – Add a new document then choose the camera and select Scan a document.

Inserting photos in Word documents – once you insert the photo, select it and go to Picture format in the menu. Choose Wrap text and select your preferred option – “square” allows you to move the photo wherever you want and the text will wrap around it.

C drive full and D drive empty – what should I do? – need to understand what is taking up the space on C drive, then try to move that to D drive – to be continued.

Can’t upgrade to Windows 11 – when should I buy a new computer? Microsoft will continue to support Windows 10 until October 14, 2025. Until then, there is no need to get a new computer, but we will discuss how to choose the best computer for you in the lead-up to this.

Term 2 Week 8 13/06/2023Scams this week – ABC article quotes a scam victim:
Lessons to learn from this article
1. Check the domain name is in the right place: Read web addresses this way:
– Find the //
-go to the first / to the right of that
– working backwards (from right to left) first you will find the Top Level Domain (TLD) such as
– to the left of that you will find the Domain name, ie the organisation whose website it is
– anything to the left of that again is a “subdomain”
2. URL (website address) starting with HTTPS
– HTTPS just means that the transmission is encrypted and so not visible to anyone who is intercepting the transmission.
– HTTPS also indicates that a “certificate” has been issued to the organisation who owns the website, that is, the organisation is who it says it is (check the domain name as above).
– it does NOT mean that the website owner can’t see the credit card details – they HAVE to be able to
– in fact the website owner can see all the details you put in. This is why you check the domain name to make sure the organisation is who you think it is.

Term 2 Week 922/06/2023SIM swapping – a bigger risk after those big data breaches. A recent ABC news article stated that SIM porting is ranked by Scamwatch as the third-most common scam this year. What can we do to avoid it? Powerpoint slides

Make sure you have an up-to-date antivirus (antimalware) on your devices (computers of any sort, Android devices). If you don’t you WILL get malware on your device sooner or later – and it’s a serious problem when you do! Choose any anti-malware that performs OK in tests at AV-TEST.ORG

My Photo Stream will be shut down on 26 July. My Photo Stream is the old way of sharing photos between Apple devices. The recommended way is to use iCloud photos which you can turn on in Settings > Photos. If you need to remove photos from your phone first, make sure you have them backed up, then delete and finally delete from the Recently Deleted album.

Does it matter if you don’t log out properly from your bank account? It depends which bank! Banks which automatically sign you out:
Bendigo – YES
Commbank – YES
NAB – possibly no
Westpac – NO

Westpac has changed the password rules for some users, but not others. HaveIBeenPwned’s Troy Hunt has this take on bank security
Alfred’s experience with Westpac passwords:
… would allow you to key in more than 6
characters and accept the password if the first 6 characters are within
their criteria. However, the system would allow you to log in as long as
you key in just the first 6 characters correctly. The remaining
characters are ignored.
