If you know there's certain times where you're not going to need to access some of the things that you're running, you can set up a sleep schedule through the OS's built in power management. 
 
Yes, that's possible. WoL is done through the MAC/Physical address, which each VM's virtual NIC will have. 

The data encryption is, but I'm not sure if you can use PSK + Authentication with SSH tunnels. I'd still go with VPN for remote network access over SSH, even if hosting on Linux, L2TP IPSec or IKEv2 is still supported and not too difficult to setup. 

If the host is Linux, then I'd say the best remote management option is SSH. You can tunnel anything else you need through this connection (e.g. RDP), which is essentially just as secure as a VPN.
This could get a bit more complicated in terms of GPU. I know that e.g. ESXi supports GPU passthrough, which allows you to make the GPU available to a guest. But afaik that GPU is then dedicated to that one guest and I'm not sure you can switch that between different guests on the fly. So gaming might be a bit of a hassle.

Assuming you mean running them at the same time, VMs are really the best way to do this. You can go for a dedicated Hypervisor like VMWare ESXi or put Windows server on it and run them through HyperV..
 
In terms of remotely accessing them, do you need to access them only within the local network or over the internet as well?
 
If it's local, then all you need is a remote desktop application. WIndows supports this natively and for Linux you could use VNC (unless there's a RDP server for Linux, I'm not too familiar with Linux) along with the appropriate application firewall rules (port 3389 for RDP).
 
For access over the internet, the above is still true, but you'd also need to allow connections from outside the network. You can technically do this through RDS and just open up the firewall, but I wouldn't recommend it. Best solution is to setup a VPN. I personally use RRAS on Windows Server, utilising L2TP with IPSec PSK. You can also use something like Softether which I believe has a Linux version as well if you want to host it there. 

Do you want to be able to switch between these operating systems (multi-boot), or do you want them to run at the same time on the same machine?
 
Because in the second case, you're essentially looking at a virtual machine host, that runs multiple virtual machines, each with its own OS dedicated to a certain task. I'd primarily go for a Linux host system and use it to run most services you need in Docker containers. Then use a virtual machine to run Windows and whatever else that can't be run as a Docker container. You should be able to manage the host via SSH and use RDP for Windows.

Having no issues almost a year in

note 8 is great, use it myself and the experience is excellent. Very long battery life. Wireless charging is neat too, there are some decently cheap qi devices.

I have the 6T so i may be a little biased, but I love the UI and the android skin, lots of people that review it say Oxygen OS is the cleanest version of android, but also has lots of functionality. For battery life the 6T will be a little better because it has 3300mah vs the 6T's 3700mah (although no wireless charging on the 6T  ). For camera they will be very close in quality. They both have amazing cameras.

Do you need/want to use the S-Pen with it's note-features? ---> Note 8
 
Otherwise, Oneplus 6T in my Opinion. Reasons below:
 
- better SoC, even better than Note 9's Exynos version (Europe. NA has snapdragon) --> better performance. Not just because of the SoC, also because of OxygenOS. Optimized for Speed.
- Newer = still faster/better Updates, and it WILL get Android 10 AND Android 11. Note 8 will probably get Android 9 as it's last Update.
- Better battery Life.
- Alert Slider
- MUCH better Fingerprint sensor placement. Even on the Back, that's one of the worst placings ever. 6T has it on the Front, and the speed isn't really worse. Samsung doesn't use the best Sensors on the market anyway so... Others are faster.
 
 
Note 8 should absolutely be cheaper than Oneplus 6T, because if it's age. 6T is still the MSRP 549€ for the base model, while Note 8 is available for 399€. That difference is fine. 
 
Note 8 still has some things going for it:
- SD Slot expansion (irrelevant, because 6T has 128 or 256gb. I doubt, this isn't enough for you
- Qi Charging (i have a Desk Lamp with integrated Qi charging field. Used it a few times on my S7 Edge, but kept using Cable, was way more convenient to use. I much rather ha ve Oneplus' "Warp charge" over Samsung's 15w charging or Qi.
- official IP68 rating (Oneplus 6T is protected, just not official to save money)
- Headphone Jack
- no Notch (Teardrop Notch > Bezel anytime)
- sharper Screen
- S-Pen, and other Samsung Features. (but no more Major updates after Pie)
- There is a chance, it might slow down after 1-2 years, like many Samsung users have it. My S7 Edge had the same issue, it never felt as fast as on release again. Factory Reset didn't help, so junk files were not the problem. Might be placebo, but yea.
 
I personally chosed Oneplus 6T (previous: Galaxy S7 Edge for 31 Months) over Note 8, over Galaxy S9(+), and of course over the Note 9 (since the latter 2 were more expensive anyway). But i still wouldn't trade it even for a Galaxy S9+, probably also not for a Note 9.
Probably would trade it for a P30 pro lol.

Define R6 would be a good option, there are few new cases available that can hold 8 HDD's in the $150/150€ price range

Both are great case builders, but also take a look at be quiet!

Do you see yourself using one? If not in near future don't or ever
If you happen to need one later there are always external ones, pretty cheap.

Gold rated PSU and that's about it. Should be about 90 bucks minus the money you get if you sell yours

You just need to work through it backwards. You've got that getVertMinDist is O(n), so (void) shortestPathHeavy is O(n2) (max of n, n and n2). You then feed that into (double) shortestPathHeavy, and while you've not posted recreatePath I assume it's no worse than O(n), so that method is O(n2) too, and just keep working backwards from there. I've not worked through it properly but it looks like it will come out at O(n2).

If you just do addrs, you're asking for the memory address of the start of the array.
 
Recall that addrs is an array of char pointers. So when you iterate through addrs, you're getting pointers.

Ok, I think I got it
Thanks for the help  

It's a bit weird. Parameter "str" would be superfluous. All you'd need is the "initial_addr" as the starting point for the search and "word", the word to search. Either it's just weird or there's some hidden catch to the exercise (?)

Thanks for the incredible response!

The thing with arrays is you can grab the address of one of the elements in the array and put it into a pointer. If you dereference the pointer, it'll return what was in that element.  So for example:
char str[] = {"This is a string."}; char* start = (char*)str; // This will point to the beginning of the array char* mid_start = &str[6]; // This will point to element 6 in the array char* end = &str[sizeof(str)-1]; // This will point to the end of the array, which is a NUL character printf("%c\n", *start); //Prints T printf("%c\n", *mid_start); //Prints s printf("%c\n", *end); //Prints nothing The fun thing is you can add offsets to pointers, since they're addresses. Since an array is a block of memory with each element only being on part of that block, this magic happens:
char str[] = {"This is a string."}; char* start = (char*)str; // This will point to the beginning of the array printf("%c\n", *start); //Prints T printf("%c\n", *(start+6)); //Prints s printf("%c\n", *(start+(sizeof(str)-1))); //Prints nothing So what they mean by initial_address is it wants some place in the string to start. It can be the address where str[0] lives or somewhere else. So if you wanted to start the search in the middle of the string, at say element 6, you'd write the call like:
// Assume str and word are defined find_word(str, word, &str[6]); //Start at the 6th index of str find_word(str, word, (char*)str + 6); //Also start at the 6th index of str  
Important: If you use an address that's out of bounds of the block of memory where the array lives, you'll run into problems. If you're running this code in an environment running virtual memory and various levels of memory protection, you'll likely get a segmentation fault (i.e., trying to access memory that isn't yours) and the program exits. But if you're running this on a system with no memory protection, the code will happily let you do whatever it is you wanted to do beyond the bounds of the array. So make sure you police yourself when it comes to array accessing in C by either guaranteeing the array won't be accessed beyond its bounds or by checking where you're trying to access before calling find_word.

Nope, I'll try it. Thx for the tip

The card itself looks sick, as for as contrast goes, can't really say.
In my opinion it might be a little bit too much black

There are multiple versions, the generally better snapdragon version 8cores (less mediatek issues, insane battery life) and the 10 core mediatek version (slightly better build quality, normal mediatek issues eg heating , fluidity issues)
 
I have used the Redmi note 3 snapdragon version, battery life is really good, cameras are meh (note 4 is a vast improvement but not better than other normal mid range phones) and MIUI is very fluid and gets frequent updates.
Get the 3/4GB version as MIUI can be very RAM hungry.
 
Anything particular you want to know?
 
FYI the note 5 series is roumored to launch on the 23rd August and could bring interesting improvements , just as a word of advice as you may want to wait.

Thanks

Space for watercooling and drives, but I might put a disc drive or Controllers
Thanks for the tip, I thought about that one or the 740

why reinvent the wheel?  implement a very light http server  (send the files using POST , receive files using GET etc ) or a very basic ftp server (passive or active only) should have plenty of java examples for that.
 
Should also have a look at DC++ works ... this uses a dedicated server software to create "hubs", where p2p clients connect and receive the information about other p2p clients that join or leave the hub (like users on a chat system). The hub server software also handles a basic chat system and handles messages from one p2p client to all p2p clients like search requests - for example p2p client A tells the hub server software he's looking for "madonna" and the hub server software tells each p2p client connected to it that user A asks if they have "madonna" on share, and then only p2p users which have a result with "madonna" reply directly to p2p client A with lists of  search results containing "madonna". 
 
 p2p clients can request file lists from each other directly without the server knowing and can also transfer files from each other.
