Thursday Diversion: Online Teaching; Apple Updates; Questions on Lenses
By Graham K. Rogers
As I have now been asked to teach two courses, starting later this month, I need to learn how to run a virtual classroom. Several countries, cities and companies have banned Zoom: the latest I saw was Standard Chartered Bank. Nonetheless it figures prominently in the list sent out by the IT experts at the international college where I have to teach. Also in the list is Google Meetings (no thanks) and Microsoft Teams, which a friend is using in industry here, and Cisco Webex Meetings.
I was able to register easily for this online with email and was sent a link to set up the password. That sent me to a login page which needed a password, so I had to use the Forgot Password option and was sent another email to link to another web page so I could set a new password. It seemed a little complex, but it was not the worst experience as I tried to set up an online shopping app later in the day which would not accept the first attempt then locked me out for too many tries.
The WebEx app for the desktop is not available in the App Store, so needs to be downloaded from the company site. The PKG file contains a process that checks to see if the app can be installed. I ran it twice and it just stopped with no information about what it was doing. I had an idea and switched to the Admin account (after putting the PKG in the Drop Box) and ran the installer from there: in one. Back in the User account, I opened the app, entered my details and was ready to roll.
I also downloaded iOS and iPadOS versions, so that I can run a session from any of the devices I have (hopefully), but without anyone yet registered in the class, I cannot test it out. Like a lot of classes, I am going to be making it up as I go along. On Thursday I saw an update to the iOS and iPad versions. WebEx is one of those apps that Siri refuses to recognise on the Mac. There was an update to the desktop app, and mercifully this was possible to do from within the User account.
Of course the moment I started to update my devices, there was a power cut at the condo. There was a massive explosion outside and I suddenly realized WiFi had gone. I completed the downloads on iPhone and iPad Pro using the personal hotspot, but was unable to install on the iPad. It was below the 50% battery level and with no power it was pointless plugging it in. It took 30 minutes for the power to come back on and then of course there is an additional delay while the condo router starts itself up, so about an hour after the cut I was finally able to install on the iPad Pro.
I also had a message on the Apple Watch later because there was an update to version 6.2.1 for watchOS.

Rather than the specifications of the SE with the A13 processor, one site made more of the 5W charger that ships with the phone when it is capable of 18W charging. There was of course no comparison with other handset makers whose phones may ship with no charger. Michael Zhang at Petapixel is positive about the camera and discusses its specifications, calling it "the best single-camera system ever to appear in an iPhone".
In many countries, because Apple would not be able to produce enough to supply all the countries it usually does. For example, each year iPhone is normally released around October, then there are second and third tier countries which have their iPhones available by late October and early November. A few more countries will get them towards the end of November, which means most markets will be supplied before the New year period.
Some of Apple's production is being switched currently to protection equipment for medics and health staff. Like many companies Apple has begun to do its part to helping those whom the governments of some countries seem unable to help, or are simply ignoring. In the middle of this silly season I just saw a note on seeking Alpha that suggests Apple should be paying a large dividends to investors. Boox Research expects a dividend increase of about $0.05 per share with the 30 April Q2 earnings announcement, despite recognizing the COVID-19 pandemic disruption. I think some analysts need to take their noses out of the spreadsheets and have a look at the world surrounding us.
On the other hand, Stephen Warwick (iMore) reports that J.P. Morgan has cut Apple's price (that's what they predict the shares will sell at) because of sales prospects over the coming months. With stores closed worldwide, the analyst does not think online sales will be enough to compensate. There is no mention of services and the recent increases in Apple Music subscribers. There is also an adjustment in share prices - this time upwards - from Piper Sandler who factor in the results of a recent survey of US teens who put the iPhone, AirPods and Apple Watch at the top of their shopping lists (MacDaily News). Last month Apple increased sales of the iPhone in China by 500,000 units.
There were several other exhortations from analysts for investors to note: some said the price would go up, some down; some said sales were down, others up, and of course there was the report on teen sales to add to the mix: despite what so many other media sources have been telling us about Android, Samsung, folding phones and all, the kids know what's what.

He now understands the limitations of the lens and asked me about what type of lens he would need for particular shots. From his description, the narrowness of the 50mm had held him back and he was after something wider, although he mentioned the idea of blurriness, which I thought he as after a lens that would create bokeh. He was quite clear on the Aperture, and when I checked he was using Aperture Priority, which I prefer. I dug out the lenses he might want and took a closeup of a bottle, to give some idea of the effects possible with each lens: 24mm at f/2.8; 24mm at f/4.5; 24mm at f/16; and 85mm at f/1.8, which gave a nice blur to the background.
