So I've read Debian 'stretch' supports secure boot, but what about Debian 8('jessie')?
Besides, do you normally turn secureboot off when installing your OS?
Can you list the advantages and disadvantages of turning it off?

I have a Dell XPS 15 9570. I want to dual boot centOS alongside Windows 10. Does centOS support Secure Boot? Should I enable or disable Secure Boot in the UEFI setting?
Thank you
It does support secure boot but with some conditions on architectures.
Only, x86_64 architecture supports secure boot with UEFI (CentOS 7).
I'm considering getting a collection of Dell PowerEdge servers. Dell documentation is pretty poor (no surprise there) and I have trouble figuring out if I can go with iDRAC Basic or if I need iDRAC Express or Enterprise.
My need is to install Ubuntu Server (minimal install with SSH is enough). After install all I need is SSH and possibly a remote "reset" button. I can install the OS before taking the system to server room so I don't really need remote OS deployment tools. However, the server does not have a graphics adapter. Is it possible to install Ubuntu with just iDRAC Basic or do I need additional hardware?
#iwork4dell Remote OS deployment implies Virtual Console (like VNC) and Virtual Media (using a remote ISO like a local DVD). These are Enterprise license features. OS deployment tools are are the driver pack that is stored in flash on the server and made available during OS installation to support new hardware on older OSes.
The iDRAC is an integrated VGA adapter so all the Power Edge servers do have a video adapter in them unless you disable it in BIOS. If your willing to attach a keyboard and monitor to the server basic is all you need. You can also upgrade the iDRAC with a license key after purchase.

and http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/idrac-spec-sheet.pdf
IDRAC is possible, just you can open gui of idrac and then launch on the online server. You can add the iso file on virtual server.
I'm trying to understand if Xen can fit my needs:
I need to have a Windows 7 image that I can copy to different machines (with different hardware) to have kind of default installation for every new entry in the office and faster replacement.
Is that possible to use the hypervisor for this?
Is that possible to use network boot as well of the hypervisor not to install Xen on every machine?
Edit: Will I be able tu use multiple displays?
Thanks.
It is possible if and only if you have installed Xen on every machine on your network that is not a good idea. Xen and other type-1 hypervisors are usually used to multiplex a high-end server into a set of virtual machines. Xen is also known for its para-virtualization technique which is not applicable for Windows.
Have you ever thought of VDI (Virtual Desktop Infrastructure) solutions? It enables you to have all your operating systems on a single machine and transfer the desktop to the clients.
I want to try Unix for developing J2EE application. I use the IBM software.
WASCE as application server
DB2 Express-C as database.
Eclipse
Which Unix flavour will be most suitable for me?
According to ibm.com: WebSphere Application Server Community Edition runs on AIX, Linux, Solaris, "UNIX" (!!!), and Windows.
According to ibm.com: DB2 Express C runs on Windows, Linux, Solaris, and Mac OS X (in beta).
According to eclipse.org: Eclipse runs on Windows, Mac, and Linux.
The only Unix flavor in common to all of those is Linux. (If you move beyond Unix, Windows also works.)
Java is platform-independent. It doesn't really matter on which platform you develop - you can run your application on any other Java-supporting platform. Hence, you can develop on Windows and deploy on AIX, or develop on Linux and deploy on MacOS, or ...
The Java VM abstracts access to operating system services and resources, as does JDBC abstract the access to the database layer.
If you really mean "UNIX" and not "Linux", I would recommend Solaris (Eclipse does run on Solaris, and it's much easier to understand than AIX).
If you mean Linux too, I would recommend a distro designed for servers, like RHEL/Centos, rather than Ubuntu or Fedora. They are more likely to be stable and scalable.
I have a production environment on Centos with DB2 and Apache Geronimo (open source version of WASCE). Works like a charm. The development environment is Eclipse and Apache Geronimo on Windows and the DB2 on Centos.
I'm planning to build Linux web development server in virtual machine environment on Windows Virtual PC. As I don't have much experience with installing and configuring Linux web servers, I wanted to ask for some advice:
What Linux distribution do you recommend for such server? I want the virtual server to look like real hosting environment.
Do any pre-configured virtual machines for web development exist out there?
Maybe some instruction and tips on configuring?
My requirements for the server are quite standard: latest versions of Apache, MySQL, PHP, probably Python and Postgre.
Thank you.
UPDATE: OK I think I'll go with Ubuntu Server for this.
You can probably go with Ubuntu. It is easy for a beginner and there is plently of documentation on how to install a LAMP stack and later you can move on to other distros.
If you are looking for pre-configured machines, then you can have a look at VMWare Appliances
For the distribution I would recommend Ubuntu - you can add all the server software you want from their repositories.
For a virtual machine I'd recommend Ubuntu Server Edition JeOS, as that won't have any un-needed software on it.
Debian Lenny - rock solid stability & the most package support
I'm sure you can find some
Use prefork-worker apache, MySQL 5/PHP 5, Postgres 8.4.
There are lots of prebuilt vmware images that you can use. You might also consider looking at something like Amazon EC2 for which there are lots of off the shelf images.
I would also suggest Ubuntu server as a base OS.
Incidentally there are other virtualisation options in case Virtual PC doesn't recognise those prebuilt image formats (I think those formats are more standardised and interoperable these days, but not sure)...e.g. there is vmware, and there is virtualbox.org
Does it need to be in Linux straight away? You can run (Apache et al) XAMPP locally and get it up and running in 5 minutes.
