App Store Connect Errors

Log of errors with App Store Connect

I have become increasingly irritated by App Store Connect - the website Apple make all developers. So I make no apology for logging all the issues and errors I have to see if its just me or whether the effectiveness of millions of developers is at the arbitrary mercy of Apple less than stellar web development team.

Infinite Loop progress indicator

In my experience clients don't understand why Apple make developers use #AppStoreConnect. It's just an 'app' they say. Why should we pay to manage it through review? In Apple's defence heres an infinitely looping progress indicator, anyone want to help me explain that to my clients awaiting publication.

System Status "All Green"

It’s all green at Apple so how can AppStoreConnect be down for developer uploads? Wait, surely it’s not just a static page - I mean the green available indicator is actually connected to something isn’t it?

An error has occurred

If it knows an error has occurred why can it not do something about it. It is after all 2022 and you are supposed to be the best technology company in the world. Every single time I use App Store Connect I have to reload pages in the 'new submission process' and that is along with having to sign in again multiple times daily too. It has been like this for months!

An unexpected error was encountered when submitting for review

Today my app skipped the new submission process altogether and just popped this error message. On refresh it says its 'waiting for review'. Who knows if it really is.

Apple worldwide developer conference 2022 - iOS 16 revealed

Apple previewed the latest advancements in iOS 16, iPadOS 16, macOS 13, tvOS 16, and watchOS 9 in the keynote at WWDC22. They explained how apps can deliver information in new ways, make it easier for people to share content, offer more intelligent features and improve productivity.

There are major innovations in sharing, communication, and personalisation. Work-life balance is made more discrete through focus. Payments are revolutionised with Apple Pay Later. And there are dozens of other major features including improvements in Photos, Mail and Messages. Fitness is now a system app for everyone not just Apple Watch owners. New Safety features for people who might feel at risk from domestic violence have been added.

TL:DR – All of this information was made public on June 6 2022.

Lotus 1-2-3 for Ubuntu 22.04 linux

Lotus 1-2-3 for Ubuntu 22.04 linux

I can't quite believe it, but I just built and installed Lotus 1-2-3 for Unix on my Ubuntu 22.04 LTS linux desktop and it works flawlessly and it is FAST!

Lotus 1-2-3 for Unix was released in 1990. I joined Lotus then to work on 'Non-DOS' products initially Lotus 1-2-3 for Mac, and other ports for Unix and Sun Workstations and then cc:Mail and Lotus Notes across Windows, OS/2, MacOS and Unix. I found an original note about the release online. I looked in my attic and found a boxed copy of 1-2-3 for Sun on a DC600 Tape! I also found a VHS of the original sales training for 1-2-3 for Unix. I wonder if I still have the demo files or presentations somewhere.

"Lotus Development Corp is following up its plans for an IBM mainframe version of 1-2-3 with one for Unix: the new version will be developed alongside 1-2-3 Release 3.0 and will be optimised for use on a variety of workstations under System V, as well as supporting the forthcoming IEEE Posix Portable Operating System, and will comply with standards set forth by the X/Open consortium of Unix system vendors; Lotus says that it will also offer multi-tasking and multi-user capabilities for easy sharing of files and consolidating large spreadsheets and will support three-dimensional and linked worksheets; robust external data access; and the extended applications facility".

Lotus 1-2-3 for Unix, running on Ubuntu 22.04 LTS,

This screen is showing off 'perspective mode' an innovation at the time! Lotus 1-2-3 had a patented and vigorously defended 'look and feel'. To get to this menu you type /wwp for worksheet, window, perspective. It is quite a revelation that I and probably most other power users can remember all these commands after all this time. You'll need a multi sheet spreadsheet though. Fortunately the installation contains the sample files. Use /fr and then arrow keys and enter key to find your install folder and sample files. This is ../root/lotus/123.v10/smpfiles/consale.wk3.

Firefox snap performance on Ubuntu 22.04 LTS

Firefox snap performance on Ubuntu 22.04 LTS

Lets have a look at Firefox in Ubuntu 22.04 LTS. Things have changed. There is some trading of benefits for performance.

"Performance is the difference between feeling like you are clicking a button or just tapping a pane of glass".

Me, at Sun Microsystems in I think 1989 after installing a new window manager on a very poorly equipped Sun Workstation

Starting with Ubuntu 21.10, the default browser, Firefox transitioned to being distributed as a snap. The benefits are confinement in the snap sandbox, authentic updates directly from Mozilla and support for any snapd equipped distribution.

The trade-offs are in performance, due to the sandboxing inherent in the snap architecture. Browser perfomance is something of a bogeyman for Firefox so this would appear to be a high priority for both organisations.

My Flutter at Google I/O ‘22 Recap

If you want to build beautiful, multi-platform native applications for mobile, web, and desktop from a single codebase with Flutter, Google's open source UI toolkit, I’d recommend ‘What's new in Flutter 3’ to everyone and the sessions below whatever your level of interest or experience.

"Announced at Google I/O 2022, Flutter 3 is the culmination of a journey to fill out the platforms supported by Flutter. With stable support for macOS and Linux apps, you can build beautiful experiences for six platforms from a single codebase."
