Hi Tommy, c...
Performant Entity Serialization: BSON vs MessagePack (vs JSON)
...becomes is your network overhead more or less constrained than your memory/cpu?
With regards to msgpack vs bson vs protocol buffers... msgpack is the least bytes of the group, protocol buffers being about the same. BSON defines more broad native types than the other two, and may be a better match...
Are arrays passed by value or passed by reference in Java? [duplicate]
... in the heap, which means that iterated lookup is much cheaper in terms of CPU time. A List does not guarantee contiguous storage.

How does Java Garbage Collection work with Circular References?
...e "root" set of places that are always considered "reachable", such as the CPU registers, stack, and global variables. It works by finding any pointers in those areas, and recursively finding everything they point at. Once it's found all that, everything else is garbage.
There are, of course, quite...
Local file access with JavaScript
...edit/read/write/delete files. You can access the hardware, such as current CPU usage or total ram in use, etc.
You can create a windows, linux, or mac desktop application with it that doesn't require any installation.

Is there a REAL performance difference between INT and VARCHAR primary keys?
...oncerns in comments.
The setup was as follows:
Intel® Core™ i7-7500U CPU @ 2.70GHz × 4
15.6 GiB RAM, of which I ensured around 8 GB was free during the test.
148.6 GB SSD drive, with plenty of free space.
Ubuntu 16.04 64-bit

Why is char[] preferred over String for passwords?
...chnically the clearing is often done with protected mode tricks and if the CPU is broken (e.g. Intel Meldown) it's still possible to read old memory contents.

What's the point of having pointers in Go?
... reasons. Pointers allow control over memory layout (affects efficiency of CPU cache). In Go we can define a structure where all the members are in contiguous memory:
type Point struct {
x, y int
}
type LineSegment struct {
source, destination Point
}
In this case the Point structures are em...
What is the most efficient Java Collections library? [closed]
...rove didn't outperform the JDK collection classes in both memory usage and CPU time. If you are using objects though (and not primitive types), then I would agree with Alex, fretting over collection impl is not as big of a deal.
