I am currently using MySQL DB Version 5.6.10 for 32 bit running in 64 bit Window OS.I want to change it to 64 bit without taking any dump..Can anyone help in this?

I am starting to get into hybrid mixing.
I’m using a Steinberg UR824 (24 bit) interface and Cubase Pro 12 using an effects loop to go through a Warm Audio 1176 and WA2A (LA2A clone) compressors.
I’m working in Cubase at 32 bit float. Should I dither before the output to the effects loop? Is this going to degrade the overall quality of the sound using this setup? Should I be working in 24 bit in Cubase? Should I upgrade my interface to 32 bit?. Any other suggestions?
Many thanks
I am trying to analyze the Excel 4.0 macro sample, introduced at https://outflank.nl/blog/2018/10/06/old-school-evil-excel-4-0-macros-xlm.
While testing, I noticed it does work well on 32-bit Excel, but doesn't work properly on 64-bit.
Eventually, I found the reason and that is: VirtualAlloc function always returns 4-byte out of 8-byte.
Implementation here:
= REGISTER("Kernel32", "VirtualAlloc", "JJJJJ", "valloc", , 1, 9)
= valloc(0, 64 * 1024, 4096, 64)
How to solve it?
You have declared the return type as "J", which is only 32 bits / 4 bytes long.
You may try "D", which is 8 bytes long, and then use a mem copy function to copy it to an 8 byte variable, or you can try putting in a dummy parameter, and try to recover the next 4 bytes from the dummy parameter.
Excel doesn't crash when you declare external calls incorrectly, because Excel does a stack check after each call, and makes sure that the stack is restored correctly.
Or it may be that 64 bit Excel has support for 64 bit longs in XLM macros, using some new type declaration-- I haven't seen that, but I guess it would be worth looking.
Is it possible to write 64-bit BigInts into a Buffer in Node.js (10.7+) yet?
Or do I still have to do it in two operations?
let buf = Buffer.allocUnsafe(16);
buf.writeUInt32BE(Number(time>>32n),0,true);
buf.writeUInt32BE(Number(time&4294967295n),4,true);
I can't find anything promising in the docs, but there's other barely documented methods such as BigInt.asUintN, so i thought I'd ask.
I was just faced with a similar problem (needing to build and write 64-bit IDs consisting of a 41-bit timestamp, 13-bit node ID, and a 10-bit counter). The largest single value I was able to write to a buffer was 48-bit using buf.writeIntLE(). So I ended up building up / writing the high 48 bits, and low 16 bits independently. If there's a better way to do it, I'm not aware of it.
Did you already try this package?

I recently started practicing binary exploitation on 64 bit linux. Problem is while chaining ROP gadgets we have to get their address on stack. But since 64 bit addresses are 6 bytes plus 2 null bytes. It's not possible to get null bytes on stack with strcpy like functions. Anyone able to do something about it yet ?
Refer here:
Return to libc chaining on 64 bit linux.
Strcpy will give problems because it won't copy null bytes. You ca use one gadget in that case.
It will still work the same with functions which copy null bytes.

I'm trying to parametrize the rocket core by changing the configuration in PublicConfig.scala.
However, when I change XprLen and L1D_SETS to 32, I have a compilation problem.
What is the proper way to genarate a 32 bit data path with the Rocket Chip Generator, if possible?
The Rocket-chip does not currently support generating a 32b processor.
While the required changes to the datapath would be minimal, the host-target interface for communicating to the front-end server (as Rocket currently only runs in a tethered mode) has only been spec'ed out for 64b cores.
ALso, L1D_SETS is the number of "sets" in the L1 data-cache (such that L1D_WAYS * L1D_SETS * 64 bytes per line is the total cache capacity in bytes).
