If you try to execute a DynamoDB query against a Global Secondary Index, by default you’ll get this error:
AmazonDynamoDBException: Consistent reads are not supported on global secondary indexes (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException
To avoid this, per answers on this question, you need to call:
.withConsistentRead(false);
on your query expression.
Although the docs here suggest queries are eventually consistent by default, apparently with the DynamoDB mapping api you still need to explicitly set the consisten read = false parameter.
Microsoft officially announced Windows 11 today. There was the usual online comparisons between the announced features and other comparable features in MacOS and Linux, like the centered Task Bar that now looks suspiciously like how MacOS’s Dock has looked for, well, years.
In the tech requirements though, there is an unusual detail – Windows 11 requires a motherboard security module called TPM 2.0. Most new motherboard apparently come with one of these, but Asus has produced a number of motherboards in the last couple of years and chose not to include one of these modules onboard. If you run the compatibility checker on a PC with one of these mobos, you’ll get this notification that your PC, that you most likely bought as recent as within the last couple of years, is not compatible with Windows 11:
Understandably, there’s a number of threads online where people are rather upset that the new PC they bought within the last few months is not compatible with Windows 11.
The good news is some AMD Ryzen chipsets have BIOS that includes embedded TPM 2.0 support, even if it’s not provided by a discrete module on the motherboard. On my Asus X570 Plus motherboard it has an fTPM option in the BIOS settings with two options, ‘discrete’ or ‘firmware’. On mine the default option was ‘discrete’ but changing it to ‘firmware’ added the support that the compatibility checker is looking for:
And now running the checker again, everything is good:
Software development is about solving problems. It’s about solving problems in an effective way that adds value. It isn’t about programming languages and writing code. Programming languages are tools. We use tools like Cloud compute to run our solutions, and we build solutions with tools like programming languages and frameworks.
It’s all about solving problems.
If you’re getting started in software development as a career and are putting all your effort into learning a programming language, remember that’s just a tool. It’s how you use it to solve problems which is the important part.
