@rubenwardy 8 a month is a lot for me :)

If you are interested in cryptocurrency discussion, a new StackExchange has been proposed which you can support:

https://area51.stackexchange.com/proposals/127389/cryptocurrency?referrer=ZTcyODU1YWEzYjAyOTg4ODYzNmNiMGRlYzJiYmRjZmExZmI0OTY2ODU0MWNiMTQ0ZmU2YWUyYjlmODk1NmU1YkZ_lQZ9lOkmQzO9EvbIgEh94sITl4jIdkmuDDulcd2Q0

Currently, you can follow it and submit example questions for this SE. If you have enough reputation, you can discuss about the scope of this SE, too. For example I am thinking if mining cryptocurrencies would be offtopic or not. But I don't have enough reputation.

@water Yeah that was the issue.

@kaia Try #minetest

@trinsec My thoughts exactly :)

Last night(Tehran time), students of my university were waiting for the bus. The forces thought they are protestors and beated them.

I am trying to calculate factorial of 30 using x86_64 assembly on Linux. Here's my code:

```
.global _start

.text
_start:
mov %RCX, 1 # counter
mov %RAX, 1 # factorial result
loop:
mul %RCX
inc %RCX
cmp %RCX, n
jle loop

.data
n: .byte 30

```

I am converting it using these two commands:

```
as file.s
ldd file.s -o a
```

However when running the executable `a`, segmention fault is raised. checking with gdb it seems that it is raised right at the first instruction after `_start`. Where am I wrong?

@rastinza No program is taking 8 GB. But #LibreOffice is extremely slow to load and when it is loaded it takes a lot of RAM. #Firefox has the same problem but I have it open all the time and I can take care of the number of open tabs.

It has been a long time which there is a question in my mind. There are cheap #sbc s around. For huge computings on CPU, would many #ARM based single board computers like #Raspberry_pi or #nano_pi replace a single #Intel? If this is possible and considering that softwares are equally optimized on #x86 and ARM, the obvious advantage of a bunch of ARM tiny computers as a whole cluster over a single x86 would be that they consume much less power, thus they generate much less heat and hopefully longer product life. Also if any of them went down, your whole computing resource is still available but with a little less computing power. I have a NanoPi NEO and a 3rd gen Ci5 M series. But a piece of software is needed which could benchmark both my x86 and my ARM and on the compiler-level, is optimized equally for both.

@marathon0 8 GB is enough for my programs.

Among the #GUI programs on my PC, I like my Terminal Emulator only. I have a slow HDD and whenever I want to open one of those GUI programs, they want to load soooo much from my Disk so they are much slower to load. Also when I don't use them for a while and their data on memory get placed in my swap space, having them back is again as slow as loading them almost. It seems that because computers have more and more memory, newer versions of programs want to waste more and more memory. #memory_waste #huge_memory_usage #linux #tech
