Nothing really unusual about this.

What you are asking is how to work remotely from TV room to your personal computer.

You haven't specified any essential details so I need to ask:

What kind of stuff you wish to do remotely?

1) Just access photos on your PC and maybe some media (music, videos streaming)?

For that you need just a simple network media player attached to your TV. Also you need a modest wifi connection between your TV and your PC. Anything that has wifi, can output via HDMI, has a remote and plays media files (photos, audio, video) will do.

2) Maybe do some office work on it?

For that you need a thin client. Probably Android based. That can do VNC or RDP. Also some input devices for that box (USB or wireless keyboard and mouse). And a modest wifi connection.

3) Gaming?

If you even think about streaming games from your PC you need a powerful wifi connection (like dual band, N standard, *fast* access points). And some device that can stream games from Steam - even small Raspberry Pi box could do that but network performance is essential.

So given above three points you need to have:
- configured wireless or wired network connection between the TV and your PC
- somekind of client device at your TV (Android based set-top box or dongle, something like PCoIP thin client, small Linux client (like RasPI))
- some input devices for your TV - depending on what you want - a remote control for media, a keyboard and mouse for workflow, a gamepad for gaming

But the one thing in common is to have network connection (wireless or wired) between the PC and the TV.

Comment Can this be installed on a dual-boot machine (Score 1) 315 315

Probably going to be told I am a noob, but:

I have a dual-boot machine. It is an Acer machine and has a legitimate Windows 7 license and I installed Linux, keeping Windows 7 in a resized partition, and occasionally boot into it (it has a bug where it will not boot without a usb keyboard plugged in so I don't do it as often as I thought I would as I have to dig out that keyboard and plug it in). Linux is the default boot. I have no "recovery disk" and I may have lost any paperwork that came with the machine but it is a real legal copy.

So the question is: can I replace 7 with 10? Without damaging the Linux install? If it screws up grub how do I get it back?

That is normal in any sane jurisdiction. In _civil_trial_ you can sue almost everyone for compensation (not for freedom restraints). Please do distinguish civil vs. criminal law. Basically in civil law you can sue anybody (f.e. me) for anything (f.e. for educating you). In criminal law that is the state or the victim that sues and the penalty would be freedom restraint (jail or something similar). In civil right there is compensation for the side suing. Usually sane countries have some protections about bogus claims. For example in my country if you wish to sue somebody on civil basis for an ammount exceeding ~20,000EUR you need to pay in a vadium of about 10% prior. If you win the trial - you win. But if you loose you also loose the vadium and you need to pay up for all associated costs.

Well this is a different question than topic subject about mobile devices. They break it because they can I guess.

> I watched people take iPhones into highly sensitive government facilities on several occasions.

They were not as highly sensitive then. If they were there would be actually some guards at the doors searching people to prohibit bringing in devices such as smartphones.

It is quite easy - you can build a really big fence. Like 20m high but if nobody is going to watch over it there would be a guy with 20m ladder... so I guess you get security wrong. If there is a policy prohibiting iPhones in certain area - do execute that policy and have guards executing it physically.

It depends but usually not. If it is concerning REALLY SENSITIVE AND PRECIOUS DATA like medical research, military contractors, finance and so on - then yes the problem exists. But usually in private sector the data is just not so sensitive to protect it with such costly measures.

Nah. They are not. If they are then you are doing something wrong.

No. That is I can use my smartphone whenever I want. No company policy forbids me that and I know nobody that has similar policy in place. In my opinion you have reached a wrong target to ask that question.

I forgot one important thing - before settling on Arch Linux I've tried different distros - mostly mainstream like RHL, CentOS, Fedora, Debian and with their release policy (as opposed to rolling releases) I recall that each time new major version came out I ended wasting entire evening reading release notes, upgrading, fixing things that stopped working etc. Now I prefer to spend few minutes weekly after each update session to act on potential small changes than to waste few hours on upgrade to next major version.

I use Arch and I can't confirm it. I've never had a problem with update process breaking anything. For me it just works as advertised. But it is essential to manage the update process. This is IMO the philosophy about Arch Linux that you need to keep control over it. Rolling releases means that there is no promise of API/ABI compatibility and of course there will be some major changes down the road on which you need to act.

When updating Arch Linux you need to read what is going to be updated. Major changes (like package replacements) are higlighted and you need to act on those changes after update. Also you need to look for configuration changes (*.pacnew files) and act if it occurs.

Also it is better to update regulary like once a week than to pile up the updates and do lots of them at once (since you can miss something important). I tend to update once a week and never had a problem. Well once I ended with unusable system after update but it was not Arch Linux related - it was a kernel bug specific to my hardware and configuration (regarding power management on laptop - it can be quite tricky on Linux but hybrid sleep/hibernation is a nice thing to have).

What problems did you have? You are stating that 1 in 4 updates cause problems so you probably can throw few examples?

Or maybe you are reffering to AUR packages breaking during update - well AUR is completely different thing from Arch Linux main repo. Some packages in AUR are of terrible quality (outdated, not working, not tested) so I guess if you have lots of obscure AUR packages installed the update process may break some things but usually it is userland. I wouldn't dare to use AUR packages for core functions of my OS (like kernel and important services).

Comment My policy (Score 1) 319 319

Personal machines:

Home laptop (primary, I also tend to work on it) - I stick with Windows 7. Obviously it is the last sane/usable version of Windows. Skipped Vista entirely. I always tend to use the Good Windows release (95, 98SE, 2000, XP, now 7). Looking forward to install Windows 10 as it looks quite sane and 7 is getting old. I apply patches automagically. With Windows it happens that some patches break stuff but it is easy enough to uninstall them. Also I run Secunia Psi to notify me about outdated apps and it also can update them automagically which is convinient.

Home Macbook (secondary, for fun) - I stick with Mavericks since I don't like the new flat look and basically it still works and apps are working so not a big deal for me. I install patches as they show up.

Home server (router, network functions, VMs for development) - Arch Linux - it is a rolling release distro so I just upgrade everything from time to time when I have security related updates pending. It works - never had broken for me.

Raspberry Pi - I use few for dedicated projects (media player, dedicated retro gaming system). When I set it up and it works I tend not to update it since I don't see the point.

Now for work computers we have strong policy. Workstations and laptops have frozen Windows version (licensing obviously, compatibilty), we push all updates via WSUS on which we accept them. We test updates on selected group of machines (IT staff) before pushing them to all. For servers we also have standardised versions (Windows, RHEL/CentOS). We roll any major upgrade through change management with backup/recovery plans in place (VM snapshots, application backups prior to upgrade i dedicated time windows etc.).

No it is not. You have contradicted yourself in your post. You have described a solution which from begining is flawed. Then you described that flaw (the kid could just change his IP to grandparents machine or even MAC if you would go for MAC based filtering). So you have basically posted a solution that is not a solution at all if you wish to make things working without beating the child.
