Ideas for IT companies

Ideas for Microsoft

Include Vulkan in Windows.
Clustered file system called MsCFS. Supporting POSIX and FUSE, NFS and SMB, and Fibre Channel and/or iSCSI.
POSIX subsystem(s) similar to SFU, so other OS's besides Linux such as FreeBSD, NetBSD, and/or OpenIndiana could be installed.
Microsoft's own X server and client for Windows Subsystem for Linux, so graphical applications can be run. Sound as well.
Free and open source base version of Windows. Still have proprietary commercial versions. Accept contributions to Windows from others. Sell the source code of Windows separately and at an additional price, and allow modifications and just not allow redistribution of the source.
Desktop OS based on Google's Fuchsia, to either complement or supplement Windows 10.
Linux distribution, perhaps called "Microsoft Enterprise Linux." Based on maybe Red Hat Enterprise Linux, at least for enterprise. Based on Debian/Ubuntu for desktop. Based on Arch for Internet of Things. Wouldn't replace Windows, but instead complement it.
Android subsystem called either "Services for Android" or "Subsystem for Android Apps" in Windows 10 Mobile. Slowed down to discourage use, like Windows Subsystem for Linux. GUI, unlike WSL.
PHP.NET, in which PHP runs on .NET Framework by being compiled into .NET intermediate language.
Python.NET, similar to PHP.NET but using Python instead of PHP.
Unixified Windows, called "OpenWindows" or something. Open as in OpenVMS, not necessarily as in Open Source. However, open is already used for open source. It wasn't until the early 90's, but now it is. And "OpenWindows" is already taken by another software (I think it's a desktop environment) by Sun Microsystems.
Single-System-Image (SSI) for Windows, similar to VMSClusters.
Job scheduler cluster software for Windows.
Collaborate with some other company like Red Hat for a new OS to replace Windows.

Ideas for VMware

Kernel mode driver (.sys file) for Windows for virtualization, similar to KVM on Linux or Bhyve on FreeBSD. Work similarly to VMware Workstation, but in kernel rather than userspace. Work similarly to ESXi, but be a kernel module in Windows rather than a standalone hypervisor. Maybe a collaboration between Microsoft and VMware. ==

Ideas for Google

Subsystems for Android and Chrome OS in Fuchsia.

Ideas for Oracle

Kill SPARC (Oracle is already planning to do so).
Kill Solaris and then make a distribution of illumos (not OpenIndiana).
JC++ (or what should it be called) - C++ running on Java by being compiled into Java Intermediate Language.
Java.NET - I don't know that this is possible, considering that Java is converted into Java Intermediate Language in the way that Assembly is converted into machine opcode. Maybe a version of Java Platform could be compiled to run on .NET Framework. Then it would be nested JVM on top of .NET CLR. I don't think it would be very useful though.
Acquire Yahoo! and Opera Software - I don't know that that's such a good idea.

Ideas for Dell

Converged infrastructure with Dell EMC Unity for storage and Dell PowerEdge M1000e. Cisco Nexus network together with InfiniBand. Compute blades should be either M640 or M830. The best Nexus might be 5500. The best Unity might be 500 and would certainly be hybrid-flash. Hybrid-flash is superior to all-flash which is overall superior to archive.

Ideas for Hewlett Packard Enterprise

Superdome that can mix Itanium and x86 blades but not on the same partition.
Converged infrastructure that can use Itanium and x86 nodes either individually or mixed on the same rack, like POWER and x86 on PureFlex System.
Note: There is already HPEConvergedSystem but it does not use Itanium. Another issue is that Itanium's last release was 9730, I think. Itanium failed because it performed poorly, especially the early versions. Itanium 2 and 9 had performance improvements, but the performance was still not as high as it should be. Itanium failed to grow and software wasn't ported to it.

Ideas for Amazon

Laptop called LapOnFire, with maybe it's own OS, either IoT like Chrome OS or desktop like Windows. Also KindleBook. Maybe base it on Chromium OS or otherwise another Linux distribution like Arch, Ubuntu, or Fedora. Or, base the OS on FreeBSD. Alternatively, base it on Fuchsia.
Amazon Music player for Linux, in Ubuntu software store.
