Comment VirtualBox (Score 1) 156

* Runs on Windows, Linux, Mac and Solaris
* Can run headless and detached from GUI
* can teleport VMs between hosts, even if they run different OSs
* free and easy to install/use.

I don't find that VMware workstation is any better in general. VMware can run virtualize ESXi easily and work as in interface to a full ESXi though.
KVM with Virt-Manager is comparable to VirtualBox IMO. It can be extended with oVirt and OpenStack. It's Linux only which hurts it for desktop, but not servers.

In general, if you need something quick on your desktop, VirtualBox is great. As you get into details, different hypervisors offer different advantages.

I develop a DVD to install Linux + Openstack on a system. We distribute as .iso and test as a physical DVD with instructions on burning on Win 7 w/ the included isoburn. Some customers can use iDrac/iLo/IPMI to mount the .iso for install or convert the .iso to a USB stick to boot that. Not all BIOS can and they're all different. We leave that up to the clueful users and lead the neophytes down the easy path with a burned .iso. I've found that burning an ISO takes less time than ubootin. On that note, is there a way to verify the DVD matches the .iso? We md5 the .iso, but the isoburn verify doesn't really verify :-( It needs to be on Windows & distributable too.

Maybe the enterprise of saving lives shouldn't be put entirely on the police? Obviously they have a role to play, but when we are talking about prevention, other institutions also have a huge role to play.

For example, many killings are the result of mental health problems that are going untreated. Part of the problem there is that the necessary care can be expensive. So....let's do something about that. What does the government-funded health care landscape look like these days? And what about educational grants (NOT LOANS) for mental health practitioners?

There is also still a strong social stigma against seeking mental health. Nobody is embarrassed to say something like "My arm was broke so I went to see the doctor," but the moment someone utters the phrase "mental health" everyone thinks of him as crazy, weak, and pathetic. This is ridiculous, and we need to put more social engineering to the task of fixing that (for example, a lot more television and movies can include scenes and dialogue implicating that the popular characters are seeing mental health professionals...and the attitude is that this is just a given that normal people do this sort of thing on a routine basis).

...

There is quite a lot that can be done, and the police can't be left alone to do it all.

Keep Sound Minds is trying to reduce the stigma of mental health issues and work toward policies that help people get help before damage is done.

I'd worry more about how to save games between sessions. How can they do that? Without leaving a browser window open forever? These Amiga games...there are a few shoot-em-up arcade style games, but most of them are in-depth experiences that take weeks or months to finish. You need to save your game and come back later.

I think they don't/won't/can't implement this functionality and thus this playable Amiga archive is worthless.

The dosbox emulator they use does save games. http://ascii.textfiles.com/arc.... It might be possible (or is already done!) for SAE

I have a 20' x 50 plot and work for a living with kids. Garden maintenance time is limited and sometimes gets skipped.

I have drip irrigation on an automatic timer. It will water in the morning when I'm at work or on vacation. I don't have to remember.

I'd love something automated that could weed, pick off pests, chase away things that eat my plants while I'm at work & at night, tell me when I have to harvest the lettuce before it bolts/gets bitter, wind the tomato/squash/beans/peas/cucumber onto vertical strings.

Not at all. The ideas behind farmbot include precision planting, precision watering, and the ability to more easily weed since you know exactly where the plants are. All of these things are increasingly important in agriculture. why are they important? Well precision planting allows mechanical weed control, and it also means water need not be wasted where there is no plant planted. Think of it as drip irrigation without the hoses and a lot more precise.

When it comes to precision planting, that's actually possible on a large scale right now, almost to the same precision the farmbot can do. I've seen 40' wide corn planters that can place a seed to within an inch of the same spot year after year (if that's what you really wanted to do). Rows of corn are perfectly spaced so that the plants are exactly the same distance apart. Automatic section control means there is absolutely no overlap even when driving back across already-planted soil. It's pretty remarkable!

Planting evenly in rows helps at all scales. In a garden, it means you can run a wheel hoe in between the plants and cut the weeds. On a larger scale, you tow a cultivator behind a tractor to to cut weeds. A nearby CSA uses a 1930's tractor & cultivator setup. Farmbot is scaling down from that.

Microsoft decided one UI should work everywhere. WinCE was the Windows desktop put onto phones. Windows 7 was the pinnacle of Desktop UI for Microsoft. Windows 8 was a tablet release, as is Windows 10. No more desktop, they want to compete with the iPad and iPhone.

You know what? The tablet UI works well on a phone. It's great for casual web, email and games. Or really anything you run one at a time like the days of DOS. If you're switching apps or running multiple apps, like the typical office worker, it's not as good. The desktop UI is great there. For a software developer the tablet is going to be harder for most.

Even *Apple*, the one choice no upgrades everything sealed Steve Jobs knows best, offers 2 interfaces. macOS for desktops, iOS for handhelds.

Microsoft needs to stop thinking one size fits all or start offering their core Enterprise apps on other platforms. Outlook (not OWA!), Skype Business, Office and Sharepoint clients for Linux and macOS. Full AD client. If they don't, enterprises will migrate away from AD, Exchange, Sharepoint to something else with a UI that works for their users.

I got my engineering degree with DOS. Everyone was issued a Z100 (non msdos!) with an 8088, Fortran and Basic. Some other programs such as CAD, PC-TeX were available. Russ Nelson worked at my college and created Freemacs, the word processor and the spelling checker and many other utilties in use at Clarkson

Some classes gave you a VMS or Unix account. When it was in heavy use at the end of the semester , it was faster to edit in DOS and upload than to scroll down the file in VMS. The DOS FORTRAN didn't have the extensions or libraries. Sometimes its math wasn't as accurate.

After I got a 286 and had gotten a Unix account (w/ Usenet access), I started trying to learn Unix things. Turbo C, GNUish utilities, Freemacs, Elvis and shell clones helped me. Minix was almost as helpful.

A 486 w/ 8mb lead to Linux replacing DOS and work as a Unix sysadmin. The DOS intro to C, awk, vi, lex, yacc (via "The Unix Programming Environment" was extremely helpful. Linux at home helped me continue learning. It could single task better than my Sparcstation 1+ running SunOS.

The 8088, 80286 and 486 systems probably cost ~ $5k each back in the day where a Unix workstation was ~ $20k if you could get one.

Believe it or not, Linux is not the end all & be all OS. There are things that other OSes do differently from Linux that might have application for real use cases.

vxWorks is a commercial real time OS uses on the mars rovers. NASA had a reason to choose it.
Contiki is another embedded OS that does things Linux cannot.
OpenBSD does security and code review. Some of it has trickled to other OSes. (W^X)
OSX runs a Mach microkernel with a BSD derived OS.
Minix is still around too.
VMware and Android both use a Linux derived kernel but do not look like Linux.
Even Windows has its place.

I currently work with OpenStack which (mostly) means Linux. I've been using Linux since '92. But I was a Solaris admin until recently and even installed Solaris 11 a few times. There are some things Solaris does better than Linux.

I've found Solaris to be more stable and better at handling loads. I had apps that ran fine on Solaris that crashed Linux on the port.
Dtrace is an awesome tool to see what is really going on with your app. Systemtap might get there.
Zones are secure, reliable containers. It's nice to finally see them get used in Linux. It will be good if they get the security up to the level of Zones.
ZFS, well it's already on FreeBSD and I've been using it for years with ZFS on Linux. I'd like to see btrfs at the same reliability. I wish *every* CLI had as good a UI as ZFS does. I'd love a GUI that was as good!
Solaris switched to SMF from SystemV type startup a long time ago. I liked it better than upstart. Systemd has been a bit smoother than SMF was at first.

Would I use Solaris for a desktop? NO! unless I had no choice. I bet most users stopped using RHEL/CentOS in favor of Ubuntu or something else a long time ago.

Oh, forgot KVM inside Zones for OpenIndiana.

Run Linux on KVM inside a Zone. Use dtrace on your Linux binaries.

Solaris is pickier about hardware than Linux.

Hardware gets ported by the vendor to Windows. Sometimes Linux, but there are lots of people that will also do it.
For Macintosh, Apple has to licence a port, but is specific about which hardware is supported. And sells a decent number of units to make it not much more $$ than the Windows version.

Solaris has so few users that the cost of the port for a graphics card doesn't get spread across many units. The driver is the cost. If Oracle doesn't sell the hardware, you will rarely see a driver for it.

Many common (scsi) cards in Solaris had 32 bit support and never got 64 bit support.

If you pick your hardware before you install Solaris, it will likely work very well on Linux.
