I know those are easy to find on children's education materials, but the keyword here is simple. Anything kiddie, requiring too many clicks or that takes 3 seconds is off the table.

I kinda need to brush up on my super basic reasoning. In part, because a grown man should know the time table by heart, and in part, because I wanna convince myself that I did not get brain damage after being hit by a car (there's really nothing indicating that, I'm just paranoid).

I'm looking for something simple that presents me with the multiplication table and or simple calculations to answer under a time frame. The requirement for iOS is that my computer is broken.

And it really can be super simple, even something I open from a mobile web browser or transfer to my Kindle.

Additionally: there is no need for if to be an app. A huge list of exercises (with answers) would be greatly helpful.

Thanks!

I figured one thread for all of Apple's new product announcements would be enough.

The new MacBook Air with the same redesigned keyboard as the 16-inch model and newer processors. I'm glad to see that they're bringing the keyboard to the rest of the lineup so quickly (I'm writing this on a 2017 MacBook Pro and this keyboard is not pleasant even after two and a half years of adjustment).

The new iPad Pro is where things get interesting. Same design as the previous iPad Pros, but now with an ultra wide camera and a LIDAR sensor.

The iPad Pro also has a new keyboard and trackpad accessory that looks interesting. It has an adjustable hinge that can hold the iPad at any angle, which is one of my biggest complaints with the current keyboard case. I'm interested to see how well it works in a lap when hands on videos start coming out.

I'm excited that Apple is bringing official pointing support to iOS (beyond the basic accessibility feature in iOS 13). This could be a game changer. I'm also excited that it's coming to iOS 13.4 (and all iPads that can run it) and they aren't waiting until iOS 14 to roll out the feature. I've wanted Apple to start rolling out features on an ongoing basis (like Google is doing with the Pixel Feature Drops) rather than as one big drop every fall.

I've been jailbreaking for years now, and one of the things that have always puzzled me was how the jailbreak community determines whether or not a tweak has malicious code since they aren't always open-sourced. With the latest releases of checkra1n, and unc0ver, I've gotten back into jailbreaking since I wanted to jailbreak my 12.9" iPad Pro. From my understanding, the jailbreak itself (usually) is open-sourced, so it can generally be "vetted" that way. I typically stay away from using too many tweaks and try to stick with those from the "more well-known" developers, but I'm curious how others decide which developers/tweaks to trust and use? Do you strictly base it on "bug-reports" and a developer's reputation? What other factors come into play? There are tweaks like "Compatimark" that helps with compatibility information (but that's not really what I'm talking about).

Edit: First time posting a topic here, so hopefully it isn't breaking any rules.

I'm currently in the process of reading the excellent "Lessons Learned in Software Testing: A Context-Driven Approach". Early on the following is mentioned.

Test common threats before exotic threats.

Seems reasonable enough. That said, it got me thinking It'd be cool to generate a list of such threats for future devs/testers to draw on. So...I'm calling on the collective experience of any Tilders involved in iOS or Android development to lend a hand.

In your time working on mobile, what issues have you encountered that you would you classify as exotic? I.e those issues that infrequently arise but when they do can cause major damage. Any and all help is appreciated.
