At our university we are being trained to use Microsoft Dynamics Navision 2013. However, one of my co-students refuses to learn and/or use that software because he claims it is dead (according to his father who is an important CIO).
Apparently Navision is 'bloatware' that went nearly bankrupt and Microsoft decided to buy it and use it for re-profit (as my co-student stated). He told me that in many companies installing Navision or any kind of Microsoft product like that is against company policy because that software is 'horribly inefficient'. I am not sure of the details.
So assuming Navision is dead, then why does my university put it in its program? Why is it 'a preparation for the business world' if the software is allegedly dead in use?

That's his choice.
But...if he choses not to learn it, then he choses to fail the course. You can't pass an exam on a subject if you know nothing about it. By all means discuss the choice of subjects with your tutor (in a friendly way, don't get abusive, aggressive, or threaten to "not learn it") but it may be imposed on him by the course syllabus and there may be no choice about it's inclusion in the course, or the final exams.
Me? I'd learn it.

So did I.

Well you don't know that for sure unless you check with Microsoft. And ask your teacher why they are teaching this subject. But mainly, don't listen to your co students, as chances are they don't know any more than you do.

Being important doesn't make one right.
Explain me in two lines what Dynamics NAV is, and what it's used for. Next, find me an alternative that's better. Once you found it, prepare for a barrage of questions demanding how it is better.

Because you'll have to learn what ERP is - which application is used is hardly relevant, as the landscape will have changed anyway before you hit the workforce.

It sounds like your class mate is full of opinions. I'd love to know what hard data he's using to back this up.
Oh, if Nav was dead, then MS wouldn't just have rolled out Cumulative Update 14 four days ago. Contrary to popular belief, MS don't buy technologies and throw teams at them if they have already killed that technology off. It wouldn't make financial sense for them to do that.
To find out what's going on in the Nav world, it's worth reading through their[^] blog.

Of course the company itself is not going to talk negatively about itself. Outside verified opinions and views are needed.

You seem to be misunderstanding the part about not throwing money at things that are dead. And how is your friends "important father" supposed to have better knowledge? Is he a Dynamics Insider? Oh wait a minute, could it be that I happen to know people who work on the Dynamics team? Surely not? Surely I couldn't reach out to them and find out if their product is dead in the water. Heaven forbid that I did that between you asking the question and my answering. Good lord, that would have been positively unprofessional of me.

Surely, if you formulate your own, they aren't "facts" but "guesses"?

Which should be irrelevant to you.

If you think that any specific technology that you use in university will be around in 50 years or even 30 years then you are likely going to be surprised. Even at 10 years some things will disappear.
What you need to do is learn how to learn about different technologies.
And accept that even if a certain technology has problems that it is very likely that you will need to still use it because businesses exist to make money, not software. And so they don't throw out everything just because of some subjective opinion (or at least not most times.)

Businesses' sole purpose is not making money. That is old-boxed thinking. Today's businesses' main goal is to make a difference in this world and make it a better world. There are also other important goals to consider such as being 'Green', i.e. Corporate Social Responsibility.
Businesses exist to differentiate and evolve our society so we can identify ourselves as a nation and not only in the economical aspect. One of the main drivers behind a business is to make software, i.e. to give the customers what they want. That is why there are courses like Software Engineering, where functional analysis and business intelligence, data mining is taught. Companies are linear organized solutions of people who put out bright ideas into the world and form them into life.
Long term thinking also has to be applied; it would be better in long term in some situations to change the business solutions rather than keeping the old ones. This is where modern consultants come in and where they show the old, conservative and obstinant nay-sayers that they are wrong in their views and that a more modern solution is viable.
It all comes down to great ideas that need to be translated to great solutions, which is something 90% of the companies today are struggling with: failure to translate Business Strategy into Implementation down the company pipeline.

Please read the post titled "How to get an answer to your question" on top of this forum.
This is the second question you asked with the not very helpful title "C#".

That's not going to happen because a TextBox only know how to render text and only in a single font at a time.
You can try using a RichTextBox, but the Word document is going to have to be saved in RTF format in order to work. Even then, the RTB doesn't know everything about the Rich Text Format that Word does and some content will not render properly.

Hi,
I need to write a High Performance TCP/IP server for receiving the data from the GPS devices and logging it to the database for display on Google Maps. There will be thousands of GPS devices connected to the GPS server and will be transmitting the data every 30 seconds and the display will be set to refresh typically every minute. I am looking for the help in specific areas, I will write the code myself and believe me I will post the complete developed and tested code on this same forum. I understand the following challenges
1.Concurrent TCP/IP connections
2.Database table bottlenecks
I would like to go for one table per device groups and different ports for devices with different protocols. I am assuming that I will need to write the following components.
1.Data Receiver
2.Parser as per the protocol and the commands
3.Data Cache
4.Database writer
Receive the bytes, log the received commands to the cache, implement the lazy writer to flush the data every minute to the database using different thread. Please comments on the following.
1.Does the GPS device disconnects after sending one command or it keep the connection to send the data further like long polling?
2.Is it better idea to maintain the thread pool and keep one thread per device? How many devices can be connected simultaneously to one port?
3.If I assume that device does not disconnect the client after transmitting the bytes to the server, should I keep the channel alive on the server to keep on reading the data every 20 seconds or whenever available?
4.Is it fair enough to have the separate threads for updating the data to the database server? Say data retrieval every 20 seconds and making it persistent to the database every one minute?
5.Is there any other better protocol rather that raw TCP/IP? I guess the other protocols like http etc should be slower as the header size itself is very big.
6.What is better choice Synchronous or Asynchronous sockets? Is it feasible to use UDP?
7.What is better choice? C# and SQL Server or JAVA and mySQL on Linux?
Many Thanks
Vipin

Not an answer but a few comments.
- No one can answer that question; you need to get the documentation for the device to see how it operates.
- Any number of devices (up to system saturation point) can connect via the same port, in the same way that all HTTP requests go to port 80.
- Depends on how the device operates.
- Possibly, but performance tests are needed to be sure.
- TCP or UDP are probably best choice of protocol.
- Again, testing will show which is best. See also point 5.
- C# or C++ and SQL (or other) server. I would certainly not use Java for such a performance intensive program, and you need a fast database.

Writing a high performance tcp server is very tricky.
You have to have a good understanding of overlapped IO. Managing kernel receive buffers, and a huge mess of stuff that's not obvious from simple 'my first tcp server' type articles on the internet
Strongly suggest you use professional messaging wrapper around tcp
Eg; ZeroMQ is something that hides a lot of these details from you
http://zeromq.org/[^]
Another possible recommendation is WCF with the tcp binding
I would not write your own tcp server just for the hell of it; it will no doubt be terrible compared to the above products
Matt.
