app question

is it possible to port iphone apps over to android?

Depends on what you mean by port. If you mean "completely rewrite to operate in a similar fashion" then in most cases yes. If you mean take the iPhone app and run it through some kind of magickal program that converts it into a functional apk... no.

yes by port i mean completely rewrite the the code to allow a program to run in a similar fashion. is that hard to do?

"Hard" is a pretty subjective word.
iPhone apps are written in Objective C with the Cocoa framework. Android is written in Java with subsets of the Java framework libraries and specialized Android frameworks. While they're not completely disparate, they are still distinct languages. The ease of moving from one language and development framework to another depends on the experience and capability of the programmer and the complexity of the codebase (e.g. it will probably be easier to port a tic-tac-toe puzzle than a rpg). Also, the more generically and modularly a codebase is written, the easier it will be to move to a different platform. Some applications are the sort that need to be supported long term (mail clients, social networking apps, etc.) These will generally tend to be written with a mind for long term maintainability and thus be written more cleanly and modularly. Otoh, apps like games and single-purpose apps tend to not be written with long term maintenance in mind. They may be written more sloppily and thus be more difficult to port without a complete ground up rewrite.
In the end though, for most development studios with real paid programmers, it's not a matter of difficulty (most modern programmers have atleast some Java knowledge) but a matter of business. In short, business development staff will calculate how much potential profit there is to be had from various options for a potential future project and typically pick that which is the most profitable. For multiplatform developers, generally that means creating cheap one-off iphone apps. Some of the most profitable apps are really simplistic things like fart apps or really simple games.

ok thank you for your help i understand it a lot clearer now. really wish i knew more than just basic javascript...

It's never too early or too late to start learning a new language, if you have the will and time. There are plenty of self-teach Java guides online.
Edit: I meant a programming language, ofc, but I just realized that that also applies to human languages as well.

[Q] WP8 C++ vs C#

Hi everyone!
Given the announcement of WP8, today, I noticed that there was not a whole lot of information of whether or not C# would receive a lot of support for developers.
I have started learning C# as my first programming language, but I am wondering if I should jump ship and learn C++ instead to write apps for W8 and WP8.
Should I? I know C++ has been popular for a while, but can anybody guess as whether MSFT is pushing developers to the C++ route and away from C#?
Thank You!

C# is definetely not being pushed away. C++ requires a lot more work than C#. You should not stop learning C#, but maybe consider learning C++ after you learn C#.

I absolutely agree with the comment above. C++, however, can let you produce far better optimized apps at the cost of a longer coding time.

Microsoft said during the Event that they encourage the use of XAML/C#, VB.Net for regular Applications. For Games they encourage People to go with C++ and DirectX. There are currently community projects aiming for kind of a follow up to the XNA framework allowing people to write Games for Windows 8 Metro using C# and DirectX which due to the shared APIs should enable the same for WP8 but I don't know how far along they currently are.
For highly resource intensive computations you might want to leverage the C++ performance benefits but overall C# is fast enough for most use cases and development is speedier and A LOT less prone to errors.

Thank you, everyone! If any more information comes up about the limitations of c# or c++, I would appreciate any ideas opinions or input!

JavaScript also joined the game.
I like C#. Performance doesn't sound like good excuse to abandon it for c++ as hardware is becoming faster all the time.

Well, the discussion about the performance between C# and C++ is pretty old. Just bing it and you'll find tons of pages. In my experience you can get very fast algorithms in both languages when you plan your app right. I'd suggest C# to learn as it is "safer" to start with. You don't have to care about garbage collection and memory management for instance. Also, you can easily reuse code in other apps. If you invest time in learning C# you will get more performant apps than by learning only a bit of C# and a bit of C++. And you can even write good games in C#. You can really get pretty darn high performant apps in C# if you optimize them right.

You've read my mind. Personally, I would also not bother whit c++ when you don't necessarily need to.
And game devs should keep in mind that using xna (c#) is the only possible way to get their games also on the xbox (And hopefully xna will get an updated version for WP8 with custom shader support and all that stuff)

XNA seems to be in pretty much the same spot as Silverlight. Microsoft is still supporting it but there is no news at all on future development. It seems development of XNA was stopped. Currently people are trying to develop replacements.
Most Apps will wok just fine using C# or JavaScript. For some things you will need to use highly optimized Algorithms. Had a discussion once with a Dev who did realtime Audio analysis on several platforms using fast fourier transformations and after all efforts on the Forum to optimize the C# code the C++ version was still twice as fast. That is simply due to some of the code security features. When accessing an array in C# the language will always do an out of bounds check to perhaps raise an Exception while C++ simply reads whatever is at the pointer position even if it is in memory behind the array as long as the memory is allocated.
By not doing these checks alone it reduces computation and given the limited processing power sometimes this is necessary to get things working decently on a mobile device.
Still there also were several benchmarks were C# code was able to outperform the C++ implementation (especially object heavy code).
So if you absolutely must have the highest possible performance C++ is the way to go. It's similar if you want to port your code accross platforms as you can do C++ for Android and iOS. In all other cases C# would be preferable as as it was said before it is more productive and less error prone.

You can use unsafe code in c# as well

To my knowledge not on Windows Phone. It would get rejected from the Marketplace. This might change with WP8 but we don't know yet.
Unsafe code also complicates things a lot because as soon as you directly manipulate memory you have to take care of it like in C++ because the Garbage Collector is out of the picture.
Most often it would be the easiest route to develop the performance critical code using C++ and then use that library from C#. This at least should be supported by WP8 although I can't remember where it was said exactly.

It's a lot better to simply use a C# UI to wrap C++ code. However, it's easier to just use C++ in that case

VB or C# for new dev

I'm a network admin who wants to start developing windows apps. I have a Masters in IT, but no coding experience. I had to take a C class, but didn't understand it. Should I learn VB or C#? I understand C# is superior, but I'm new and don't understand the concepts. I know they both use .net and I'm wondering if VB would be a good way to start or a waste of time? Thanks
Sent from my RM-893_nam_tmous_201 using Tapatalk

First of all, if you remember *anything* from C, C# will be more familiar.
Second, in terms of an employable skill in the job market, C# is more valuable; not only is it in greater demand in general, it's also closer to both C++ and Java, both of which are in very high demand.
Third, while VB.NET is a perfectly reasonable modern language with plenty of nice features, that modernization + same anachonisms it has held onto has led to it reaching a state that I consider no easier to learn than C#, so between the two of them I'd certainly recommend C#.

I can not say that I have personally done a lot of vb development, but based upon what I have seen of it, I would certainly recommend c#. C# is quite similar to other powerful languages such as c++ and Java, so after developing a solid understanding of c#, getting familiar with these other languages will be a breeze. It provides the best integration with the .net framework, and has simple and easy to understand syntax. I think that c# is more of a replacement for VB than anything anyways, and as such, learning c# is the best way to go:laugh:

Java and C# only have in common the common object class and similar syntax to some extend.
C# is way more powerful than java and comes close to C++ as far as complexity is concerned.

C# all the way. The way it is built and the constructs of the language itself, makes it easy to learn and enjoyable to code with. And I've use both Java and VB in a little enviroment

Functionally, there's no difference between C# and VB.NET. Anything you can do in C# you can also do in VB.NET. The syntax of VB is much easier, and is overall more easily picked up, but C# is more common, and more useful in the industry.
If you look at code samples a lot, and use C#<>VB.ET converters, you can pick up the syntax of both of them, so even if you found a code sample in VB you'd be able to work out how to code it in C# easily.

I used to hack exclusively in BASIC and VB. Now I work pretty much exclusively in C# (and the very similar powershell) and would encourage anyone else to use it too. It's FAR more useful than anything BASIC.

VB.NET and C# are virtually identical in capability (the both compile to MSIL that is processed by , so in terms of what you can do with them, they are equally useful. The main differences are how easily you can do certain things. With that said, though, C# (as a "C-like" language much like the very widely used C++ and Java languages) is more professionally useful that VB.NET (which is a "BASIC-like" language, a language family that is dying out in the professional world).

C# is almost identical to Java, and Java is very popular now. If you learn C# very well, learning Java is a matter of hours away and then you can easily port apps to android too

why importance of technology in education?

In the field of education, technology has an important role because with the help of technologywe can cam make easy to education. Also, technology provides a lot of study materials through which you can learn anywhere in the world.

People have lost sight of the fact that, from an educational perspective, the most important technology ever created was the printing press.

With technology, students have a wider range of resources to learn from and a wider range of resources to conduct fact checks. I'm not sure of all the other benefits but that's all that comes to mind.

Sure. From another perspective, technology is an enabler in education. It is high time the brick and mortar universities decided on how to cut cost and embrace online learning platforms.

I cant put it any better.
But here are some factors that make me favor the integration of technology in education.
Firstly, most teenagers right now started using phones right from childhood therefore integrating mobile education just make it simple for them to grasp some of the concepts. Besides, with the introduction of Virtual Reality and Artificial Intelligence, it can only get better .

Technology is very useful in these for education. Even the school students have smart class, they can understand the concepts easily.

Education should be literate and tecnology...
Teachers themselves not only need to be literate, but they must also ensure that their students are able to access the information they need, are capable of determining the relative merits of the information obtained, and are able to represent the information they have gathered in new ways using the different forms of media available to them (print, video, audio, digital).

At present, technology has been imposed in our daily lives, therefore it is a vital need to learn and master them, since everything that surrounds us implies technology in one way or another,

With all lockdowns, technology is used more than ever for teaching and learning...

It will be useful if technology is implemented properly. But so far there's been a lot of bad attempts

It's pretty important for any essay writer to compose unique texts for the customers. If it would be not unique, client can refuse from the payment.

AI/CAD Robotics teacher's!

It's almost impossible to imagine education process without using tech in it. Agree?
For example https://idscan.net/. Employing student ID scanners and school visitor management software dramatically improves school safety and security by denying access to unauthorized individuals and granting access to those approved, all in real-time. Did you even know about that?

"The media is the message."
Hmmm...
Technology is the message.

I am interested in 3D printing and I think it’s a great idea to use 3D printing in educations. It is not easy to have young students figure things out without the benefit of visualization. A visual learning environment improves their understanding of the world, being able to touch and see their projects. It’s a great opportunity for graphic, geography, chemistry students. But 3D printers are expensive, and many educational institutions don’t have enough funding to buy them. I hope, this will change over time.

Just imagine I can study the language practising with a native. I'm sure that people have had no such opportunity for a couple of decades ago. And that's the basic thing that I could mention. The internet is a huge library where you can find everything you want. Also, it is possible to talk about the newest technologies like VR. It is insane.

Not near everything and it can be heavy censored/search biased.
Example, wiki keeps editing critical info out to fit their left and god knows what agenda.
Example, entry David Hedison ie Capt Crane from the TV show Voyage to the Bottom of the Sea was in the Navy. He was also a pretty good Navy boxer. It helps explain his physical prowess in fight scenes... it was real.
This critical fact was completely omitted by wiki.
Even chemical entries have been altered over the last few years removing important properties.

Technology is very important in education. Continuing education is crucial. That's why platforms for online learning are very good. MOOCs offer the opportunity for lifelong learning at international universities. You also get certifications. Free and available to all. Many websites are also a good source of knowledge. XDA is one of those websites. Without internet access all this wouldn't be available. The most important thing is that education never stops and various new technologies will make continuing education possible for many people.

Technology makes education more engaging, interesting, and you can get more information rather than using old books.

Educational pointers for developer (incl. AI/metaverse)?

To the people who have been here all along:
I grew up in the 80s immersed in technology; having intrinsic skill with computers (from building PCs to application and web development), I naturally had a successful career in IT. (My passion has always been live, data-driven apps, and I have broad experience with SQL in the back and ASP.NET/JS/etc. in the front.) Unfortunately, I was unwell, self-destructed (got caught up in what amounted to an elaborate theft scheme), and went to prison.
Now that I'm releasing, I'm trying to find educational resources that will catch me up to speed in the industry so that I can restart a career in development for mobile devices. But web searches return what appears to me mostly junk. I believe that you folks will be able to point me in the right direction.
As a lifelong coder, I don't need a basic introductory class; that being said, my familiarity with specific environments only goes so far. Which programming languages do I need to learn, and can anyone refer me to particular resources that would best take advantage of my pre-existing abilities so that I can develop apps for Android, iOS, and alternatives?
Perhaps more importantly, I obviously need a leg up in AI and metaverse technologies. Especially because these are evolving fields, I'm not sure whether I need instruction in a particular application so much as a general tour -- but looking for something like that runs the risk of returning terrible wastes of time for someone in my position. I'm thinking I need a little of both, but choosing the platforms in which to invest my attention is going to require more than a web search.
Ideally, in addition to public-domain type materials, I'd like to gather a short list of remote-learning programs, possibly instructor-led and therefore having a structured schedule, but whatever works. I care less about obtaining a valued certificate than I do about getting the right kind of training for me so that I can actually pick up the knowledge necessary to inform my next steps.
Any pointers would be immeasurably appreciated! Thank you for reading.

You will need Java - Kotlin for Android , Objective C for iOS. And good understanding of how modern IDEs and software work.
https://www.freecodecamp.org/ is the best resource you can have for understanding current software scenarios.
AI is old. We always had AI
Metaverse is old. We always had Metaverse.
Modern tech companies are also the world's biggest marketing companies. Both fields are hyped by these companies.
