As for BlueStacks removal, make sure you've gained the admin rights and, you've completely exit the app, including its background processes. Here's how to perform the manual uninstall, read it if you need extra help.
More, reviewing the attempts you made to get BlueStacks would also help perform...

My friend is traveling to the states next week for a short time then he'll be back to England , I would love to ask him to get me this very unique xbox controller.
He doesn't have to carry it with him of course instead he will keep it in his luggage. Would it cause him any problems?

Though, I only have a very broad understanding... there's lots of good resources for more detail.
Generally, the C runtime will request a block of virtual memory from the OS.
That's a syscall, which is platform-specific.
mmap on Linux, Unix. HeapAlloc on Windows.
This happens when you malloc.
This memory is allocated in a giant chunk to your process.
The OS doesn't know about any of your in-process data structures.
The C runtime handles the splitting of this chunk into smaller blocks. There's some bookkeeping data attached to each block.
So a block might look like this:
(The bookkeeping data can go anywhere... maybe at the end of the block, etc., very implementation-dependent. Beginning makes sense cause it's easy to find from the pointer.)
Then it can look up the size and mark that block unused.
Usually you'd also have a free block list, which can be simply implemented as a linked-list. There's more efficient and advanced structures possible, though. This is the pool of blocks malloc can allocate from.
Malloc will search the free block list for a block big enough to satisfy the request. It can also break blocks up to make them smaller, and merge small blocks to make a large one.
The process of merging blocks can be very slow. It also only works on contiguous blocks. This is also why a process with a fragmented heap can take up a lot more virtual memory than actual used memory.
When you free, the newly-freed block is added to the free block list.
Depending on the implementation, if there's enough free blocks it might decide to reduce its virtual memory allocation by resizing its heap using syscalls.
> The GNU C library (glibc) uses ptmalloc,[11] an allocator based on dlmalloc.[12]
Memory on the heap is allocated as "chunks", an 8-byte aligned data structure which contains a header, and usable memory. Allocated memory contains an 8 or 16 byte overhead for the size of the chunk and usage flags. Unallocated chunks also store pointers to other free chunks in the usable space area, making the minimum chunk size 24 bytes.
@JesterTran Implementation-dependent (again! noticing a pattern?) but it could mark the block unused in the bookkeeping data and add it to the free block list. That would be enough.
It could even just mark it unused and forget about it - then you'd end up with a block that could never be used again.
Or a dumb implementation could simply do nothing at all!
Of course, then your memory usage would never decrease and repeated malloc+free calls would eventually run out of address space.
The 'common pool' (possibly not typical terminology there) would just be a set of one or more mmap allocations that are split up by malloc into smaller pieces as I originally described. This would be used for small malloc requests.
Apparently modern mallocs will just allocate larger requests directly from the OS via mmap etc.
@JesterTran Just keep in mind that it's a very rough and probably outdated overview :P
If you want specifics, there's lots of docs available.
Can anyone explain how malloc() works internally?
I have sometimes done strace program and I see a lot of sbrk system calls, doing man sbrk talks about it being used in malloc() but not much more.
I want to know how malloc and free work.
int main()
{
unsigned char *p = (unsigned char*)malloc(4*sizeof(unsigned char));
memset(p,0,4);
strcpy((char*)p,"abcdabcd"); // **deliberately storing 8bytes**
cout << p;
free(p); // Obvious Crash, but I need how it works and why cras...
I got a spam email, offering email spamming services. I mean 'Mail Blast' services. And apparently the whole mail was images, and they want people to contact them over the phone.
They do have a fax number. Pity, I don't have a fax machine any more.
LOL, you should have seen the crasy Html/scripting Art Show I just saw when trying to find/download a hard to find driver for a mostly obsolete ethernet card. semantic.gs/… (probably 100% EVIL link)
If you have a safe type of computer , and dont (of course) run the exes and all, you could see there by starting a download, insane layers of cuteness , worthy of its own youtube Video , that i am not really sure why they even did that.
Assuming they actually would have had the (oh) 56K sized driver (max package less than 1 meg ever) it did a video routine that took 5 minutes , making it look like they were "checking" the files and "packaging" and "virus checking" and "processing" much processing :-)
Yea it was my last hope for finding the driver, but before running anything on this "ethernet" driver, for some reason the ini was for a mouse , and serial mouse ? WTH , with 2 disclaimers that "we wont be responcible for anything" Oh your disclaimer wont protect you (US based) they got laws.
The web has gone to hell in a handbasket, and googles magic search adjustments still puts Layers of fraud in the first of the search.
Top off the fact that the first 2 pages of search for a driver are Fraud, when searching to see if the sites were "trustable" (yea 2 pages of that too) all the idiot sites claiming to "trust" and "review" the sites all put it between 70-100% trustable :-) most of them 100%
i know that even the illegal ones (too) have less malware than trusted sites, stuff I have even paid for that has stupid toolbars, browser hijacks and add-ons that sweep in (or try to) off some server that who know what is going in.
it probably took about 80times as much fluff , and bandwidth than it would have taken to actually provide the file in the 4-8 seconds it would have downloaded.
and not to forget the capcha , that made it look all protected for thier server, that was the SAME text every time :-)
Snake Oil Show comming to a town near you.
Yo! if you can do all that for a 1 minute glance at your worthless sponcors, think what you could do with a real job.
If people like that end up as walking dead in the zombie apocalypse, I would be all to happy to . . . laugh and leave them like that , forever.
and the fun didnt end, downloaded Foxit, to read a few PDFs. What the F--- Did you do to your program :-) what once was a really nice small free pdf reader, went all godzilla on my computer. 2 malwares , full page advertising , cloud connections and 15 minutes to get the little beast under control. IF i had known, wouldnt have done it.
Any ideas on how to build a Z170 system on a very limited (<US$500) budget with a strong foundation (high-grade motherboard, good SSD, etc.) with easy expansion from there?
I'd rather get a high-end motherboard and replace the CPU later.
I'd also prefer to not have to migrate a Windows installation to a larger or faster disk. (PCIe storage is not a requirement.)
Discrete graphics is not a requirement for the initial build.
The focus is to start with a strong foundation and limit the need to replace parts as upgrades are performed.
Is $500 too little? Something's telling me I need closer to $650-$800 to properly get started...
I guess I'll continue to save up. PCPartPicker shows I still need about $1200 for the baseline due to expensive parts that cannot be eliminated from the equation.
