That Ezra Taft Benson, while true, is one of the dumbest remarks I've seen, and is used by some groups to put down government.
The point of government is to take your money and do what's best for the people as a whole. You can argue that isn't what happens in some cases, but that misses the point.
Government generally is the only entity that takes risks when the reward isn't obvious. That where just about all of our technology comes from because industry won't invest without the promise of fairly quick rewards.

I could write pages on this but I fear aside from not being read, it would wax far too political for the lounge.
I was anarchist for 26 years. I didn't so much leave it behind as I evolved, just so you have some idea of where I'm coming from. I've never particularly been a fan of states.
That having been said, you're essentially right, with the following caveats:
Governments are complex adaptive systems. In lay terms, they consist of so many people that they take on a life of their own. The actions of the whole are not necessarily reflective of its individual agents.
The problem with this is such systems either grow or they wither and die. Stasis is rare.
And they defend themselves against attempts to undermine them. Positive** prospects like limiting government do not limit government, they create defacto private government with state power and no accountability.
** i'm not using the term like "good" - i'm using it as in active vs. passive
That gets dangerous and ugly when the continuation of the system is more important to the system than acting out the will of the people it's supposed to represent.
And all of them fall down under the right or rather, wrong conditions. No system can perfectly contain the potential for revolt.
So with those limitations in mind, I think it's a good idea to be wary of government, but I think most people regard it as necessary because anarchism doesn't scale.

That's certainly not the point of the U.S. Federal gov't. The constitution makes it very clear that the Federal gov't is supposed to protect the people from foreign enemies, and not do much else that gets in the way of individual freedom and liberty.
Of course certain forces have corrupted this to great extent.
The difficult we do right away...
...the impossible takes slightly longer.

I have seen a similar quote attributed to Thomas Jefferson. I think it is less about government per se, but more about the scale of government.

+1 for this suggestion. Performance is much, much better than using the managed classes for memory mapped files. (I remember we clocked this being around 5x faster). We used this approach to store multimedia fingerprint data.
Here is a small snippet of code showing how we initialized the memory mapped file using C++/CLI - The data is accessible through the _pData (UInt32*) member.
Int32 StationHashStorage::Open() {
msclr::lock lock(_syncRoot);
if( _isOpen )
return 0;
String^ fileName = GetFullFileName();
_szInBytes = ComputeFileSizeInBytes(fileName);
String^ mapExtension = GetFileExtension();
String^ mapName = String::Format("{0}{1}_{2}", _stationId, _date.ToString("yyyyMMdd"), mapExtension);
marshal_context context;
LPCTSTR pMapName = context.marshal_as<const TCHAR*>(mapName);
{
msclr::lock lock( _openLock );
_hMapping = OpenFileMapping(FILE_MAP_READ | FILE_MAP_WRITE, FALSE, pMapName);
if( !_hMapping ) {
LPCTSTR pFileName = context.marshal_as<const TCHAR*>(fileName);
_hFile = CreateFile(pFileName,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ,
NULL,
OPEN_ALWAYS,
FILE_ATTRIBUTE_NORMAL,
NULL);
if( !_hFile )
throw gcnew IOException(String::Format(Strings::CreateFileFailed, GetLastError(), _stationId));
_hMapping = CreateFileMapping(_hFile,
NULL,
PAGE_READWRITE | SEC_COMMIT,
0,
_szInBytes,
pMapName);
if( !_hMapping )
throw gcnew IOException(String::Format(Strings::CreateMappingFailed, GetLastError(), _stationId));
_usingSharedFile = false;
} else {
_usingSharedFile = true;
}
}
_pData = (UInt32*)::MapViewOfFile(_hMapping, FILE_MAP_READ | FILE_MAP_WRITE, 0, 0, 0);
if( !_pData )
throw gcnew IOException(String::Format(Strings::MapViewOfFileFailed, ::GetLastError(), _stationId));
Int32 dummy = 0;
for( int i = 0; i < _szInBytes / sizeof(Int32); i+= 1024 ) {
dummy ^= _pData[i];
}
_isOpen = true;
return 0;
}
void StationHashStorage::Cleanup() {
if( !_disposed ) {
if( _pData ) {
if( !UnmapViewOfFile(_pData) )
LOG_ERROR(Strings::UnmapViewOfFileFailed, ::GetLastError(), _stationId);
_pData = NULL;
}
if( _hMapping ) {
if( !CloseHandle(_hMapping) )
LOG_ERROR(Strings::CloseMappingFailed, ::GetLastError(), _stationId);
_hMapping = NULL;
}
if( _hFile ) {
if( !CloseHandle(_hFile) )
LOG_ERROR(Strings::CloseFileFailed, ::GetLastError(), _stationId);
_hFile = NULL;
}
_disposed = true;
}
}

So write an unmanaged assembly with C++ to do the heavy b-tree lifting...

There's already a ton of B+ trees in C++
I was going for a managed code version that would run on any .NET capable platform.
I have one that's in memory. I just need to make it diskable, but it's easier said than done.

You do know about the System.IO.MemoryMappedFiles namespace, right?
MemoryMappedFile Class (System.IO.MemoryMappedFiles) | Microsoft Docs[^]
If you have a C++ version of your app, you could run them side-by-side and compare performance.

Yes, though it was added to .NET after my initial attempt at using mem mapped files from C#.
Besides all that is is a wrapper like the one i had written years ago.
It doesn't change the basic problem which is:
var foo = new int[1000000]; //backed by disk, paged automatically, in C/C++
it's mainly because you can't use pointers in C#, and even if you use unsafe, you cannot pin objects to specific addresses in memory

I'm aware of that. I worked on the Visual Studio team at microsoft. I know a little about .NET

I'm not sure why you feel the need to tell me that you worked at Microsoft. If you were trying to imply that it adds credibility to what you say, I've go to tell you that I've met some real nimrods who came from Microsoft to those MVP summits I used to go to.
I'm sure that a number of exceptionally talented people work or have worked at Microsoft, but there are also these nimrods (who thought they were exceptionally talented). A random sample could belong to either camp.
Because you had to say that, I had to say this.

No I'm telling you i don't need your lectures about the very basics of how .NET works.
I don't care if you find me credible because your opinion doesn't matter to me. If that were to change, we'll talk.

I responded to you with a couple of one liners, and you term those as "lectures"?

That's probably why you tried desperately to establish that you're sooo good with announcing your "Microsoft backgroundz"? Geez, try and make some sense occasionally.

You started this buddy by being a complete dick and jerk to another member here. You can finish it by just saying "I'm sorry -- won't happen again." Not to me, but to the other member. Or you can just sod-off. Until then expect to be treated by me like I see you treating others.

I had an argument with another member (admittedly heated), and we're through that, and that's that. If you don't like that, you can sod-off (follow your own advice).

I should care? I might have had to take you seriously if you had anything to show as your own contribution to this community, like an article or a few awards. And you're trying to act like you've some business with how two other members have discussed, trolling on a two day old thread.

Contradicting yourself. Typical sign of faulting thinking.

Yeah, you should care. As if you have anything to show yourself. Awards or no awards, doesn't matter. You should care how you interact with others. Be human. Not an animal.

Let me see if I could start it on a clean slate with you.
Your primary accusation is that I started off by being rude to this other member. This is untrue, because my first two messages (on different parts of the thread) were:
1. A suggestion that a native programming language is more suitable for performance oriented tasks (not to mention the "should work across platforms" requirement).
2. The op pointed out some "flaws" with the .NET framework, which I said were basically not flaws, but by design. (how could one have raw pointers that could be used for manipulating memory on a framework that promises to automatically manage memory for you?!)
The other person basically responded to me telling something amounting to "I worked for microsoft and I therefore don't need you telling me about .NET", which I did not like. I pointed out that working for microsoft doesn't automatically make someone very intelligent.
The discussion went downhill from there, and the OP had some condescending stuff to say as well. A bit of back and forth, and the OP said they don't like me and that they will block me. I thought that was fair enough as we had had a heated exchange.
But then you show up and falsely accuse me of "starting out by being a jerk" and here we are.
