Yes, while i'm working on node.js, i still love perl, :)
The old web product is based on old perl CGI, i'm looking to the simplest way to fix XSS/Sql injection/etc. web security holes, within a week including testing, :(
So for
Catalyst
Dancer
Mason
Maypole
Mojolicious
which one should i use in the ARM platform ?
Thank you !
You have fallen foul of the primarily opinion-based off-topic categorisation, and your question will probably be closed very soon. However I think it's worth offering a few guidelines here
First of all you should absorb what is written in CGI::Alternatives as it is a reasonable summary of the subject
Next you should separate the HTML generation functionality of your existing CGI code from the interface itself, and consider replacements for each of them separately. If you were to use HTML::Tiny together with CGI::Simple then your code would have to change very little and you would have achieved better partitioning of functionality
Ideally you will move on to one of the many templating systems such as Template Toolkit, together with one of the frameworks, which is the topic of your question. In the end you will need to do a lot of research and many trials to discover how well each framework fits your requirement, in terms of both the feature list and the convenience and clarity of the API
All I can do here is say that I am very fond of the Mojolicious suite and suggest that it may be a good starting point. The API focuses on command chaining in a way similar to Ruby, and there is a Mojolicious::Plugin::CGI accessory which will allow you to execute CGI scripts unchanged during your migration
Note however that all of the frameworks that you mention, as well as several others, will have their proponents. That is why you must make the selection yourself, as such recommendations will be influenced primarily by familiarity, and without your own knowledge of the requirements of your project
Unfortunately I cannot speak to the security issues of the various options, but I hope that has helped a little

If there is any PLC programmer or Twincat3 user out there. I would like to write my master thesis on Twincat3 in a company. Basically, They have different kinds of the Test bench, and they want someone to develop drivers for them. I have no experience with PLC or C++ or IEC61131 languages. Is it possible to learn any of these in 3 months, and then start writing the thesis? I have three months of Internship time before starting. I am having a bit of doubt. Even though it is daunting as an Electrical engineering student, I have no other options.
I thank you in Advance.
Also, The test benches are mainly Powerelectronics or Electrical machine test bench. I believe I need to automate the test processes in twincat3.
Best Regards
Good choice with TwinCAT 3. TwinCAT 3 is very capable, and quite easy to learn (of course dependent on your background, but generally a good platform to work on).
All I can support you with is a link to a TwinCAT 3 tutorial that I've created that is free of charge (available on YouTube):
https://www.youtube.com/playlist?list=PLimaF0nZKYHz3I3kFP4myaAYjmYk1SowO
There are also some other resources available both on YouTube and on the website. I've created a set of links here to help you find all the resources you might need.
To answer your question I would say it depends. Three months is not much time, especially considering you probably have a lot of other things that need to go in there (doing studies, writing the thesis, implementation, conclusions etc). It depends on the complexity of your project (it's not very specific what "writing drivers for them" means). If it's a simple project (including a very basic set of I/Os) it might be do-able. If it's anything more complex (like needing to add a front-end, doing motion control and maybe even safety) then it's most likely going to be hard to finish it in three months.
But again, I think more details on what you want to achieve is necessary.

We're evaluating ITextSharp (now known as IText) for producing pdf documents. This will be used in our websites which will be published across a load-balanced solution amongst several servers.
According to Itext, this will require a production license per server (we're not open-source) in our load balanced configuration, as well as uat and developer licenses. This is obviously a considerable investment.
Could anyone recommend any alternatives to reduce the costs?
Also, is there a pattern we could adopt to minimise the migration effort of the existing website prototype if we were to use another product?
You could change your architecture a bit and have a dedicated PDF generation server. You'd then need to boil your requests down to something that could be sent between the servers. Depending on your goals, that could be something relatively simple, such as a user ID and a report name, or complex (text layout, that image there).
As far as distancing yourself from the commercial iText, there are two options.
1) Use the older MPL iTextSharp. It won't have all the latest features and bugfixes, but it's hard to beat the price.
2) The "wrapper" design pattern. Build a relatively generic interface, and have your current implementation of that interface sit atop iText. If you later need to swap it out, you're rebuilding the glue code, not your whole app.

I want to go with Xamarin.Forms project. Now, I am bit confuse for consuming Rest API for this project. Performance matters.
There are many available but can any body please suggest me which should be best for Xamarin.Forms(.Net Standard)?
Microsoft Http Libraries or third party libraries like Refit, RESTSharp, PortableRest, etc.
Please suggest
All of these options are viable. I think the performance differences between these libraries will be marginal. So, it mostly comes down to what you feel comfortable with.
I like to use Refit because it will take a lot of redundant code out of your hands and you just have to focus on the contract. All the code for the actual calls is generated at compile-time (and thus won't impact your performance at runtime).
Also have a look at how well the library is maintained and if it's active. If you choose one that is already inactive for a while, chances are that you will start relying on older software versions which might not be what you want.

I have been evaluating DNN over a few months. It has it´s pros and cons. I find it hard to evaluate systems by reading articles and don´t have time to check them all on my own.
What are your general feeling about this?
As my background is with .net, which system would you choose?
Also, does anybody know if these pages at stack overflow is based on a CMS and if so which?
Since everyone would rather spend more time criticizing your post than answering it, I'll give it a shot.
You have a few options with building a portal. Either go with an established, open source portal (like DNN), look into some paid solutions or build your own.
Open Source - I've worked with DNN and MojoPortal. DNN is a little slower and has a few more requirements to develop skins and modules, but it has A LOT more features and some of the free/paid modules are really cool. Overall, DNN wins here, but if you don't need a large portal and you want to keep development really simple, MojoPortal might be better. MojoPortal has a few nice features that makes it easier to configure.
Open Source (Other) - There are tons of them out there. Orchard is one I'm thinking of because I'm interested in MVC. But, it's still young in terms of features and support.
Umbraco - I can't really speak to this because I have not used it, but it does have some popularity.
Build it - This is an option and allows the most flexibility, but it takes a lot of time and so many features that are built into these portals could be left out. Role based access, page management, page/module permissions, downloadable modules, profile/profile properties, file management, skinning, acct management, menu management, event logs, etc
I left out non .NET solutions like ones based on PHP, Grails, etc because you are a .NET developer. There is plenty out there, but sticking to .NET will help speed your development up.... unless you are just wanting to learn something new.
Hope this helps.

I was wondering how people think about using productivity tools like Coderush or Resharper in live demos. Is it a don't and should someone only use the most default settings of the IDE? Or is it ok to speed things up a little during the demo? Also, should you explain you are using this tool during the demo?
I've seen a lot of presentations where people use these tools and personally I don't mind.
Make sure you tell people that are going to be using the tool and then announce the action that you are about to take. e.g. "I'll use Resharper to extract this method into the Foo class"
It really depends on what you want to demonstrate. This kind of productivity tool are usefull even for demos in order to avoid loosing time on basic technical problems. You may also take advantages of such demos to introduce the features of these tools...
I tend to use DevExpress Refactor! Pro, and GhostDoc, when I do code-related presentations. I try to make sure the audience knows what I'm doing by saying out loud what I'm going to do, but I have also built my own custom tool for this, which you can find a beta of here: LVK.ScreenKeys.
Basically the tool will pop up, in the upper right corner of the screen, yellow tooltip/toast-like windows showing the key stroke/sequence I invoked, and also a textual description of what it means, depending on the software it was invoked in.
Before I started using such a tool, I invariably had questions like "what did you do now", and if you don't want to use such a tool (there are others besides mine), I would consider not using more than a few functions of such tools.
