I'm going to produce VoLTE packet stream on OMNET++. Which OS is recommended for installing OMNET++, Linux or Win?
My laptop system is win10. If Linux is better, is there any problem if I use linux on VBox?
Thanx for your kind recommendations.
Linux [1] is definitely the recommended OS for using OMNeT++.
In particular, you will have the best experience with Ubuntu 18.04.1 - if you're using the latest OMNeT++ release that is. Older versions might work better on earlier Ubuntu releases.
Running it in a virtual machine should not cause any issues.
The only case that might be problematic is using the 3D integration (OSG and osgEarth). Rendering performance might be worse (or it might not work at all), but this depends on your setup. There are a few GPU/driver/config/etc. combinations where even this works quite well.
EDIT:
The reason is that even though Windows is fully supported as well, it simply performs significantly worse - especially during building either OMNeT++, or any model libraries or projects. We suspect that it is caused mostly by how NTFS works, among a variety other things.
On top of that, certain "more exotic" features in some model libraries might only be available on Linux.
[1]: Well, technically it's GNU/Linux, or more appropriately, GNU+Linux. :D
I suggestion Linux (Example : Debian, Fedora) or Unix, Because Linux or Unix have most stable using develop OMNeT++ to working great.
i was wondering if it is possible to host Windows PowerShell on a .NetCore application assuming that i'm gonna use it on Windows OS, but couldn't find an answer for that.
anyone knows if there's a way to do that?
No it is not possible.
Windows PowerShell only runs on Windows, PowerShell Core runs on Windows, Mac OS and Linux.
You'll find more information about that in this article: https://www.ghacks.net/2018/01/12/powershell-vs-powershell-core-what-you-need-to-know/
I am looking at options on how to make a multi-platform Java application run on system startup. There are obviously ways to do it manually for any application (e.g., "How to Make a Program Run at Startup on Any Computer"). Unfortunately, they are all different and depend on the operating system version and Linux distribution. I need to support at least:
Windows >= 7
macOS >= 10.12
Ubuntu >= 16.04
Raspbian >= 8
It would be awesome if Install4j already has a way to achieve this.
There is a "Add a startup executable on Windows and macOS" action in install4j.
On Linux/Unix there is no general solution for this problem, so you have to do it yourself for the particular environments that you want to support.
I want to test my web application on Internet Explorer 9 but I don't want to buy a copy of Vista/Win 7 on my developer machine with Windows XP.
Anyone knows a workaround, free and easy?
Use another machine.
Or better, get a set of Virtual Machines established which have an array of operating systems and browsers installed. Build enough VMs, and you are covered for all eventualities, regardless of whether you would personally use them or not.

You can't. The closest you'll get is IE9Preview.
I've found that IETester is not a bad way to quickly switch between browser versions for testing.

You can try running Wine on windows.
This will let you emulate a newer version of Windows
However, it will be really buggy (not mentioning how Wine is already buggy)
Its a unix/linux application ported for Windows

IE 7,8,9

In unpaid version you have 3 minutes to test any site accessed from Internet on any browser.
In paid version you have unlimited sessions and ssh tunneling.
It seems that the Windows Phone 7 SDK doesn't support running inside a VM. On Parallels, the entire VM simply crashes when the emulator is starting up.
Around the web, though, a few people have reported that they were able to use it by changing a lot of the VM settings.
What do I have to change to be able to run it? I'm specially interested in Parallels, but VMWare or any other simulator that run on OSX if fine for me!
The WinPhone7 (and WinPhone8) emulator is itself a VM and few (if any) general-purpose VM's will host another VM infrastructure, which is why it crashes Parallels etc.
If you want to have the emulator run from within a different VM to the one MS provides, then you're into the realm of extracting images, toggling bits and trying to tack it into your VM of choice. Of course, the chances of the emulator then working as expected with no residual issues is as close to nil as makes no difference ;)
[Update 2013-01-30] VMWare5 & Parallels Desktop 8 now support running Hyper-V guest VM's. This is particularly useful for those wanting to develop against the Windows Phone 8 SDK which runs Windows Phone 8 guest VM's on Hyper-V.
Here's a guide to how to run Visual Studio 2012 & Windows 8 SDK (inc. the Windows Phone 8 Hyper-V-based emulator) in VMWare5 or Parallels desktop 5: Link
Note: Running Windows & Hyper-V inside a VM will be slower than running natively. Dual-booting into Windows (using Boot Camp on OSX) is stil the recommended method of developing for the Windows platform, especially if you want to use Hyper-V guest VM's.
I'm working in VMware Fusion with Expression Blend 4 RC AND the emulator.
works like a charm!
As others have said, WP7 is itself a virtual machine. Even if you can get it to run inside a virtual machine like Parallels, the performance will be abysmal. If your computer supports hardware virtualization, the emulator runs really smooth, without it it's very very sluggish. Running it inside another VM will make it even more sluggish - I am guessing to the point that it's unusable.
I know this is not the answer you want to hear, but I would recommend running Windows in Bootcamp, you will have much better experience developing and emulating.
I'm not so sure about compatibility for long term development, but in last september, I remembering trying the Windows Phone 7.1beta SDK on VirtualBox (I'm using mac SL), a free virtual machine from oracle (previously by Sun) and it works well there.
I just do a regular install of Windows 7 Home Basic (any Win7 except Starter will do, CMIIW) in the VBox with no tweaking at all, install the GuestAddition inside win7 (provided by VBox), then install the SDK. I create new WP project, arrange UI, make some codes as usual, then run it in emulator. Surprisingly, the emulator works fairly well and showing the app I've developed.
I'm not even experience any lag (my macbook is i5, 4GB ram, the VBox setting is dual core, 2GB ram, note that no other heavy mac process is on the run, so I solely run the VBox ... and iTunes for listening musics).
So if you still want to try WP SDK 7.1 on VM, why don't you try VirtualBox? My current VBox is installed with Windows 8 and have no extra space to reinstall the win7+WPSDK. If you do give a try on VBox, please report the result here to inform everyone.
I've run the Android emulator inside a VM before. It was slower, but still usable to test basic apps. Also, the Android emulator was then slow to where you couldn't tell a difference from between native or from within running Eclipse from within a virtual machine running Linux
x86-to-x86 emulation tends to be pretty fast nowadays due to both Intel and AMD CPUs having hardware to help it along. A lot of x86-to-x86 emulation also doesn't do a full emulation (see Android's emulator to see how a full emulator runs in comparison). In the x86-to-x86 case, the faster ones will try to pass as many instructions to the host OS so that a chunk of the code runs natively
People have made claims like 80-95% performance, which is pretty good. If you have a 3.2 GHz CPU, you get knocked down to around a 2.4 GHz equivalent of your CPU. That's not bad at all, and I honestly don't notice that much overhead running in a good x86-to-x86 VM
The biggest reason why the WP emulator has problems with VMs doesn't have to deal with it being a VM-in-a-VM, but it's most likely that it requires DirectX 10. This might have to do with XNA, which is Microsoft's really nifty gaming API that lets you easily port between Windows, WP, and the Xbox 360. A lot of VM programs don't support hardware 3d acceleration
On another note: if you want to use a low-end system, AMD CPUs may fare better since AMD doesn't tend to disable hardware virtualization features in their lower-end CPUs
If you're deploying to a device, you should be able to use a VM, since it's the emulator that has issues being a VM itself.
We have successfully deployed, and performance is acceptable in our environment, virtual Windows 8.1 Pro Desktop under VMware vSphere 5.5 (ESXi 5.5), and have the Windows 8 SDK and Emulator working correctly with no performance issues. (In Education - to University Labs for Windows Phone development).
The issue experienced by most, is you most have the Hypervisor pass through the Intel-VT into the VM, to effecticely create Nested Hypervisors. This is possible using VMware vSphere 5.5.
This option is available in virtual machine version 10, enabled in the vSphere Web Client - Enable Hardware Virtualisation.
