Hi ,
What versions of Spring and Java does this book cover ?
In my current work environment, I use very outdated versions of both and would appreciate going over modern versions with a quick overview.
thanks,
Paul

Hi,
Who is the book geared towards ?
I'm an experienced programmer but new to Python. One of the main reasons I've been putting off learning it is time.  I also learn best by doing projects so this book seems ideal .
Another reason I've been putting it off is that I don't  see a need for it  at my work. Do the projects apply to something that might be useful in a professional setting?

thanks,
Paul

Thanks Alexey .
That is an important distinction.

Hi ,

I like the example based approach you take in the book.
What would you say is the main difference in approaches to programming a  machine learning application compared to programming a traditional business/crud application?
thanks,
Paul

Thanks Michael .
I'll check out the sites.  

Hi Michael ,
I'm not familiar with the concept of Micro Frontends.
From another answer you posted ,it seems that Micro Frontends are kind of like a wrapper around multiple web applications.

How would this vary from a web page with multiple hyperlinks  on it ?

thanks,
Paul

Thanks for your entertaining response Cay.
I haven't had to use JQuery in a while but it went from 'this is great' to 'this is a nightmare' -  especially when maintaining existing sites.
It is surprising the number of hoops javascript developers will jump through to not learn SQL and manipulate all their data in a browser.
I would definitely benefit from reading your book.
Cheers.

Hi Cay,
I was wondering what your view of various Javascipt libraries is ?
The options out there are mind boggling. It's sort of exploded in the last 5 or so years.
Does your book cover any  in particular or behavior differences between browsers ?

In the past, I've had some frustrating experiences with JQuery in particular ( behavior in different browsers and also inconsistencies with different versions of JQuery) .    

Thanks,
Paul

Thanks for your input Michael.
If Web Assembly reaches it's goal of working/interpreted the same in all browsers then that is a step up over Javascript and speedy applications in a browser opens up a lot of possibilities.

Unfortunately, for most applications, reliability is held by management to be of little account. In fact, I was terminated from a job position once and the excuse given was that I spent too much time on reliability instead of just "getting it done". This was a shop that considered it more acceptable to reboot one of the production servers once a day when it went South rather than have someone actually fix the offending software.

One of the great virtues of open-source software, however, is that there's rarely the quality-reducing pressure to be "productive" and often a lot of desire on the part of the designers to try out some flashy new technology (not that commercial developers don't also have that itch!). So it's open-source and those rare institutions which still support Research and Development over just pushing any old trash out the door in order to make this quarter's profit goals who tend to make up the early adopters. Only if/when tangible benefits appear is wider acceptance likely. I have little doubt that a lot of people who encountered Java in its early days disparage it because it wasn't lean and clean like C.

There used to be a saying that nobody ever got fired for buying Microsoft. There has always been conflicting goals of business and the development departments. Now that hacking is costing real money ,businesses are actually committing more resources to "getting it right" . Regardless of the tools ,there are a lot of badly written programs out there . Sometimes it's time constraints ,sometimes it is just inexperienced programmers.

Thanks for pointing out one of Rust's advantages .

After going though  getting the Second State example working  and reading the article "https://www.secondstate.io/articles/is-this-the-next-java-20200713/" ,there is nothing that impresses about this.
It's basically a node app that makes calls to server that runs compiled functions. The article says the "Rust is beloved by developers"  . I would counter the number of developers that it is beloved by is very few .
Maybe if you spend a couple months learning it ,you are forced to feel you love it but there was nothing in  the Rust documentation that made me think "Cool ! I need to know this".

I really don't see what the hype is . There is nothing there, especially if someone has worked with C or C++ before.

I'm going to spin up a Vagrant box and try "Rustup". I'll let you know what happens.

Thanks Tim.
I just the got the second state "helloworld" example to run on Docker on a mac. Seems to be the perennial issue of "nothing useful working on Windows 10".

Tim Holloway wrote:Sorry, I didn't mean to interfere with your chances of scoring free swag. But I'm too blind to see where Docker got mentioned there. And the best place to get help for Docker is in our Cloud forum, I think.

I did a quick check of my own and there's a Rust project at the Docker hub that allows you to create your own custom Rust container from a Dockerfile.
...

Personally, I'd probably spin up an independent VM if I wanted to be able to play with Rust temporarily .

The instructions mentioned the Rust project and it has been a nightmare to get running. I tried running the   Docker Rust project under Windows yesterday and got errors about it not existing on Docker so I tried to set it up in a Kali virtual machine under VirtualBox but trying to set up Docker for the last hour on the VM has given me a list of hash sum errors from Docker.

I thought the author's project would be quick and easy thing to just check out. I was completely wrong on that.
I don't see his project killing Java any time soon.

Mis-classiffied reply

I don't understand why my question was moved.  It was a direct response to this : in the first post in this thread.

everyone who completes a programming assignment wins a Raspberry Pi Zero kit.

The directions the author offered in his contest did not work for me .

Hi,
I'm trying to follow your instructions.

When I call  "docker pull secondstate/ssvm-nodejs-starter:v1 "

I get "error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/images/create?fromImage=secondstate%2Fssvm-nodejs-starter&tag=v1: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

"
Docker is running .
docker - v returns the version I have  -19.03.8

I'm able to pull and push other repos.
It looks like the repo exists on docker hub. What is the issue ?
thanks
Paul
