Thanks.

Hi,
When you look at the environmental impact of the IT industry as a  whole , most developers would point to the impact of big players : Bitcoin mining (individuals and large  mining farms),social media server farms, AI companies  ,etc ... - as to where our focus should be. From personal perspective ,I gave up years ago just trying to get people to turn off their computers at  night when they left work.  

Does your book offer any  metrics for the actions that it proposes  for it's target audience ( I'm guessing it's probably not Zuck or Sam Altman) ?
thanks,
Paul

Thanks Jeanne for the explanation. Lombock sounds interesting. Seems really useful or a pain depending on the use case or real world experience. Thanks everyone else for their opinions.

So , The good news is that the Java compiler seem to be in your Windows environment path.
If the compiler is working from the directory where the HelloWorld.java file is then two things to check are : Does the case match in the file name. Java is case sensitive. Also try compiling with the full path included.

Hi ,
I've been at the same job for a while. I was wondering if Spring is still the dominant group of frameworks that people are currently using? For example, I've never heard of Prometheus or Project Lombock.
Thanks.

answer posted twice.

It depends on the  "Stake holders" .

On the business side it's always:

1) Cost
2) timeline
3) current trends

On the technical side it's:
1) The level of complexity. Usually the more complicated it is, the worse it is.
2) Available resources

In general ,whoever your stake holders are ,you have to be able to state your case simply.
Know your audience.

Hi,
This is a common issue that will come up repeatedly as you develop with Android. Android is not backward compatible.

When you come across issues like this , think in terms of libraries and components.
"android.support.v7.widget.Toolbar" is the  "toolbar" component in in the "android.support7" library .
You need a more current library for the Toolbar component  that is compatible with the version of android that you are using to compile and targeting as output.

To find out what you need remember : Google is your friend. Textbooks and tutorials in android are often out of date by the time you read them.

Here is a result I got  that uses a more recent library . They use 'androidx' instead of 'android' .

good luck.

Hi ,
I recently worked with a software architect who was not a very good programmer. It seems like that would be a pre requisite for being a software architect. Most other software architects I've come across are very good programmers.

What are your thoughts on this ? Can someone do  a good job on designing a system that they don't know how/are not able  to implement?

thanks ,
Paul

Hi ,
I've been curious about quantum computing for some time but have no practical knowledge of it.
I'm wondering how rigorous does ones physics knowledge have to be to benefit from your book ?
thank you,
Paul

Thank you Heather . Good luck with the book.

You lie.

I have been guilty of that and it worked out. That's how I got my first job .

Tech recruiters and HR departments are indeed pretty clueless for the most part.
Some get it but most do not. They just want to check boxes.

The thing with relational databases kills me. They really are all the same. Just some different bells and whistles .

Hi,
I'd like your insight into  an issue that has come up repeatedly in my career when I tried to switch technologies that I was using.
Recruiters  only respond to resumes that have a significant relevant professional experience in a language or technology that is required for  a particular  job.

For example : I might know Python well but not used it at a previous job or used it in a limited capacity. I see a Python based job that I can do.
How do I break through the recruiter/hiring manager wall than says I am not a Python programmer and my resume is cast aside?

Thank you,
Paul

Thanks Venkat .
That a good suggestion. Familiarity is a temptation . I've also seen in it the code of people I've worked with.
ie. A new project but coding style is  15 years old.

Hi ,
I'm sure this is covered in your book but was wondering what you consider the biggest advantage of using the streams API over the collections API for handling data ?

A sample use case:
You want to iterate through a list of email addresses . If the the email is in a second list , you  send an email then handle a bounced email or do further processing after the mail is sent if not bounced.

For me, it would make more sense to use an iterator for that.

thanks,
Paul
