alvas's questions

From How to install cling?, I've downloaded the pre-installed binaries for cling-ubuntu on https://root.cern.ch/download/cling/

$ wget https://root.cern.ch/download/cling/cling_2017-03-30_ubuntu16.tar.bz2
$ dtrx cling_2017-03-30_ubuntu16.tar.bz2
$ cd cling_2017-03-30_ubuntu16
$ ls
~/cling_2017-03-30_ubuntu16/$ ls
bin include  lib  libexec  share
~/cling_2017-03-30_ubuntu16/$ cd share/cling/Jupyter/kernel/
~/cling_2017-03-30_ubuntu16/share/cling/Jupyter/kernel/$ ls
build        cling-cpp14  cling.ipynb           clingkernel.py  scripts
cling-cpp11  cling-cpp17  clingkernel.egg-info  __pycache__     setup.py

On the documentation, it says:

pip install -e .

But when it comes to the step:

# register the kernelspec for C++17/C++14/C++11:
# the user can install whichever kernel(s) they

Which C++ version should I use? I didn't have any of those installed? I use gcc to compile my c++ code usually.

And even when I tried installing all with:

jupyter-kernelspec install cling-c++17
jupyter-kernelspec install cling-c++14
jupyter-kernelspec install cling-c++11

The Jupyter notebook shows the kernel but at the home page but when I create a new notebook, the kernel either dies or keeps restarting.

So when I tried to install libcurl4, Somehow my dependency tree screwed up:

alvas@ubi:~$ sudo apt-get install libcurl4-openssl-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:

                        Depends: libkrb5-dev but it is not going to be installed
                        Depends: librtmp-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I've tried:

It didn't work so I clean:

And then I did this:

alvas@ubi:~$ sudo apt-get install libcurl4-openssl-dev

Reading state information... Done

How can I resolve the dirty dependency tree so as to install readr in R successfully?

I do have proper internet access and my current IP (in the UK) is 82.47.29.14 but my laptop is still linked to the German server 91.189.91.24 80.

How should I resolve this problem so that I can do-release-upgrade?

After following these commands from https://askubuntu.com/a/159371/63298, it removed my sources.list and when I do sudo apt-get upgrade, it's asking me to auto-remove the packages lost.

How do I revert my source.list from the source.list.backup? Now my source.list.d is a directory and not a list.

Tensorflow is a numerical computation software http://tensorflow.org/get_started/os_setup.md#binary_installation

The installation instruction says to simply pip install on Ubuntu but I'm getting the following error:

$ sudo -H pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl
tensorflow-0.5.0-cp27-none-linux_x86_64.whl is not a supported wheel on this platform.

My Ubuntu version:

alvas@ubi:~$ lsb_release -a

My kernel:

Any clues on how to install tensorflow in ubuntu or to resolve the platform problem?

The instruction from this link works to change from DHCP dynamic IP to static. But there's a step where it says:

You need to also remove the dhcp client for this to stick (thanks to Peter for noticing). You might need to remove dhcp-client3 instead.

And then:

sudo apt-get remove dhcp-client

Is that really necessary? If so why? Is there any other way without removing dhcp-client?

How many threads should I run on this machine?

My lscpu says there are 96 cores. Are those physical cores? What is the maximum and optimal thread that I can run on this machine?

https://stackoverflow.com/a/10670440/610569 show that I can run over 20 threads per core. Is that okay? Is that optimal?

Pardon my noobiness in cores/threads.

I am able to get a size of a directory at the end of the du -h directoryname. But is there a way to get the size without it listing the files/directories within?

I'm currently doing it like this:

du -h directoryname | tail -n1

How to keep an index of directory sizes? Is there an Ubuntu application/software for that?

Doing a df -h:

alvas@mt:~$ df -h

How do I check whether my sdb and sdc drives is mounted? And if they are, where are they mounted?

**What is GPT (GUID Partition Table)? **

How do I check which disk is used and which disk is still a clean slate

How can I mount all spare unused drives into a single directory?

If not a single directory into separate directories in /media/?

It's strange because fdisk showed 5 physical disks but mount can only find 2:

gillin@mt:~$ mount /dev/sda1
mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab
gillin@mt:~$ mount /dev/sdb1
mount: can't find /dev/sdb1 in /etc/fstab or /etc/mtab
gillin@mt:~$ mount /dev/sdc1
mount: can't find /dev/sdc1 in /etc/fstab or /etc/mtab
gillin@mt:~$ mount /dev/sdd1
mount: according to mtab, /dev/sdd1 is already mounted on /media/2moretb
mount failed
gillin@mt:~$ mount /dev/sde1
mount: according to mtab, /dev/sde1 is already mounted on /media/shiny
mount failed

Using gparted, I've found sdb and sdc` but they're unformatted and they looked unused but is it really safe to use it? My machine had a RAID 1/0 system but i'm not sure what is the specific settings.

How to make sure that it's safe to format sdb and sdc? Does the available space on the gparted ensure that?

I realized that my server has many processes runned by lightdm:

Can i killall processes from lightdm?

Is sudo killall -u lightdm safe?

I encountered a SIGBUS error when starting up eclipse. There was nothing wrong before this, I've just turned on the laptop and the error appears:

Has anyone had the same problem before? How do I resolved the problem?

Is it an IceTea JRE problem? I have tried installing the latest JDK with this: How do I install Java? but it didn't work.

The SIGBUS error in hs_err_pid4159.log is http://pastebin.com/w8YqFJE3

I've also tried this and it didn't work:
