Not exactly seeing what's wrong with those screenshots,

TT

the two area where the red line is show the same typed text

right side its ok left side in a QT wallet its not

that affect users who dont use english keyboards

as long as not fixed i can just use rokos like a VPS with putty ssh and console
that means lot of the added value of rokos is lost for non english keyboard users

In localisation. You can change characters tables for all apps somewhere. I'll check at home if I have the same issue in qt but I dont think so. I think I have used console with fr keyboard and no issue.

Thanks for the feedback, perks of innovation, will look for sardokan feedback also,
and should be worked out for the next release.

Id guess can copy/paste from where the layout is properly writing to the one that doesn't (maybe a small work around meanwhile)

Odroid C2 vs Raspberry Pi 3
http://hackaday.com/2016/03/02/odroid-c2-bests-raspberry-pi-3-in-several-ways/

we want ROKOS supporting Odroid C2 please

I'm having trouble compiling DMD for ODROID C2 with Ubuntu 64 bit, any plans to release 64 bit version of ROKOS?
Trouble seems to be with qmake and make scripts (only armv6 and armv7 cases are checked for, need to add support for armv8).

build/scrypt_mine.o: In function 'scrypt(void const*, unsigned long, unsigned int*, void*)':
scrypt_mine.cpp: (.text+05c): undefined reference to 'scrypt_core'

Atm Im waiting for the Pi 3 and most expected PINE64+ system (very similar specs with this ondroid)

I ll be able to work on them and share the new OS when i get the devices, as for Ondroid yes, we could release a version for it after, so I
can order a device first and do proper testing on it when done with the Pi 3 and PINE64+ releases.

Definitly gonna do this. How hard is it to get other coins on here ?
I have
DMD, OK Cash, Transfercoin, Netcoin, Sprouts, Evergreencoin, Bitbay, Hyperstake,Primecoin
and will be adding
Solarcoin, Gridcoina and Qara

Are the ones that aren't on Rokos hard to add ?
Awesome job btw. It's slick!

Odroid C2 is very similar in specs to Pi 3, but has 2G ram vs 1G for the Pi3.  
uname -p returns aarch64, it is running ubuntu 16.04 64 bit (still experimental release due mid-April).

But it's only 1.2GHZ :~

The Odroid C2  is 2GHZ Quad core and 2G ram

Would that affect how many wallets I could have open ? Want something that can have like 10-15 wallets open

ram is of main concern for number of wallets open.  but u will also need more speed from cpu for that many wallets.
where u start to run into problems is when u are using swap file ...

So would I see a real world difference with 2 GHZ ? I'm just gonna use it for wallets.

I would think so, I would not run more than 4 or 5 wallets in 2G ram, monitor the system with top from the command line and see how much swap is being used ... u don't want ram swapping to SD, the have limited write life span.

So what would the cheapest solution be for me if I just want 15-20 wallets open 24/7 ?
Cheap laptop or something ?

What is the way to move swap file to hdd ?

on a SBC I would imagine USB drive.  With ROKOS I don't really know but I would start with /etc/mtab.

[utahjohn]

I have rokos on a pi2
My hdd mounted in fstab

But the swap in rokos is not a partition but a swap file and I don't know how to set it up.

I will google it

I'm running Ubuntu 64 on Odroid C2 so ymmv.

I would NOT recommend USB drive as this will only SLOW system down.  Best solution is RAM, and limit number of wallets, run multiple RPI for a few wallets each.

I should be running some stress tests with the PINE64+ as soon as we get it, I feel it could handle that quantity of wallets
in their node instances (non graphical) , else just get 2 devices and should have no troubles, will know for sure after it gets here.
We are official backers for the PINE64+ IoT device as well.

how do i change the swap size?


Use the following command to change the default swap size:

Code:

sudo nano /etc/dphys-swapfile

Make sure it reads CONF_SWAPSIZE=1024
Use the left/right arrow keys to navigate the file.
After change is done, press Ctrl+O followed by the Enter key to save the file.
Then, press Ctrl+X to exit the editor.

Use the following commands to enable the swap file with its new size:

Code:

sudo dphys-swapfile setup

sudo dphys-swapfile swapon

You can check the new active swap size with: 

Code:

free -m

What is the way to move swap file to hdd ?

you dont really need to move it, i would not recommend, it could bring other issues by doing so, by increasing its size you should have no issues,

if still want to do for testing, you could try creating the new swap file on the hdd and just change it on fstab:

sudo mkdir -p /var/cache/swap/   # create a driectory that holds the swap file
sudo dd if=/dev/zero of=/var/cache/swap/myswap bs=1M count=4096 # for 4 GByte
sudo chmod 0600 /var/cache/swap/myswap # only root can access
sudo mkswap /var/cache/swap/myswap # format as swap
sudo swapon /var/cache/swap/myswap # announce to system

Insert the following line in /etc/fstab for swap from the next boot:

/var/cache/swap/myswap    none    swap    sw    0   0
