How to bypass what seems like a MAC-Adress ban?

So my problem here is I got banned in this online mmorpg because of some reasons. They first banned me on my laptop and then also on my computer because i was dumb enough to use an account which i created on my laptop and they could track it down that its the same owner. So my question here is how can i bypass this MAC ban? An moderator told me that they are working with encrypted MAC adresses and sent me mine (i dont know if i can trust him if its really mine) I already tried to change my MAC adress with a software called “Technitium” but i still couldnt get access to the game. Does someone knows what the solution for this problem could be? I tried to use also a virtual machine but they can track that down and block all kind of access from virtual machine. I would be really thankful if someone can help me with this.

16.04 not booting. Mounted it on 18.04, data seems fine. Repaired Grub

Been raked over the coals with this one.

16.04 crashed while running. Could not even get grub to come up. It is not a dual boot system. Only 16.04. Just screen flashing. No command line access with no ability to read log files. No ability to go back to run level 3 (systemctl in ubuntu). Nothing.

At first, I reinstalled grub from an 18.04 trial install. After that I Was able to select “ubuntu recovery” on boot but with no effect. Same flashing of the screen with no command line access.

I’m sure that it is not a physical problem with the disk. A few weeks ago this same thing happened on another drive. I cloned the drive with DDrescue to another drive. Data was ok. The problem followed the new drive, implying that the problem was in the operating system. Somehow, not sure how, I was able to boot the new drive.

Now I am “in” the new drive and the same thing happened.

Loaded 18.04 on top of 16.04 and I can mount 16.04 and see programs, data.

Is there a way back from this? I don’t want to have to download 300G on another drive at this point (downloading that much data is expensive).

Thank You Tom

Why multiplying float number by multiple of 10 seems to preserve better precision?

It is famous that for float numbers:

.1 + .2 != .3 

but

1+2=3 

It seems that multiplying floats by 10 allows you to preserve more precision. To further illustrate the case, we can do this in python:

sum([3000000000.001]*300) #900000000000.2957  sum([3000000000.001 * 1000]*300) / 1000 #900000000000.3 

By multiplying each element in the list by 1000 and divide the sum of the list by 1000, I can get the “correct” answer. I am wondering: 1) why it’s the case. 2) Will this always work, and 3) At what magnitude, will this method backfire, if it will.

Installing GalliumOS kernel, adding repo seems to fail

I’m a newbie to the Linux world, and trying to get a nice linux install on my Chromebook Pixel. This, it turns out, is not easy.

I’ve been trying to follow this guide:

How to install GalliumOS Kernel onto ubuntu installation Acer Chromebook 14

But when I get to the un-elaborated step “Add the GalliumOS repo”, I run:

sudo add-apt-repository "http://apt.galliumos.org/" 

I get

E: The repository ‘apt.galliumos.org bionic Release’ does not have a Release file. N: Updating from such a repository can’t be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.

And then there is no /etc/apt/sources.list.d/galliumos.list to edit. I try to create a new one, but it wont let me place any files in that folder, and wont let me grant myself permission in it.

What am I doing wrong, here?

Correct resolution in xrandr but seems incorrect

Every time I remove my two external monitors and then plug them back in the resolution seems incorrect.

Output from one of my external monitors:

HDMI-2 connected 2560x1440+1920+0 (normal left inverted right x axis y axis) 725mm x 428mm    2560x1440     59.95*+  74.97      1920x1080     60.00    50.00    59.94      1920x1080i    60.00    50.00    59.94      1280x1440     59.91      1680x1050     59.88      1280x1024     75.02    60.02      1440x900      59.90      1280x960      60.00      1280x720      60.00    50.00    59.94      1024x768      75.03    70.07    60.00      832x624       74.55      800x600       72.19    75.00    60.32    56.25      720x576       50.00      720x480       60.00    59.94      640x480       75.00    72.81    66.67    60.00    59.94      720x400       70.08 

It does not, at all, feel like 2560×1440. If I go to whatismyscreenresolution.net it shows 1280×720, which feels more correct.

I usually solves this my mashing some xrandr commands and restarting my computer several times. But it must me a correct way to solve this.

My second monitor:

HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm    1920x1080     60.00*+    1680x1050     59.88      1280x1024     75.02    60.02      1440x900      59.90      1280x960      60.00      1280x720      60.00      1024x768      75.03    70.07    60.00      832x624       74.55      800x600       72.19    75.00    60.32    56.25      640x480       75.00    72.81    66.67    59.94      720x400       70.08  

I have disabled the laptop monitor, so I am only using the two externals.

I tried the --scale 2x2 option. It then looks correct on the HDMI-2 output, but I can not access the right half of the screen with my mouse.

Having trouble installing epson driver, seems related to Python?

I am having trouble installing the driver for my Epson scanner and I have had some issues in the past installing other things. It was suggested that this was a duplicate and I ran into the same error. When I do ./install.sh (for the driver) or something similar, as here, I get the following error code:

It seems Xubuntu does ´touch´ a microsd card in a way that is recognizable by retropie for instance – what does it do?

if i for instance insert one of my Retropie microsd cards in my other desktop pc which runs Xubuntu 18.04 LTS, if i do not lock the microsd card with the switch in the SDHC-microsd card adaptor, Xubuntu ´seems´ to do something to the card, in a way that when i put it back in my Raspberry Pi, the Raspberry starts searching folders and other stuff before the initial boot of emulation station. This is a significant symptom i get when i have inserted any microsd card in an other pc or device, when it was not set to be Read-Only. I run Linux Xubuntu 18.04 LTS on all my systems btw. But what does it do with a microsd card which is not Read-Only, and i did not do ANY fileoperation (copying/ deleting whatever) on this card, I only made an Disk (.IMG) with Disks of it. Can anyone tell me what Xubuntu ´does´ to a microsd card inserted in this way. ? It does not corrupt anything but i should assume if i do nothing like copying to it, or deleting from it, there should be ZERO traceable actions of this microsdcard having been inserted in an other computer … ?
