Reminder: Arch Linux uses pacman not apt-get
So I had an idea that I wanted to be able to leave my room and still see the progress of a download from my phone. I have looked for preexisting programs but have found none, so I decided to write a program myself.
the first step I took was reading the pacman documentation, to see if a function that could get the current download status was. I know there is a file I can check to see if exists
/var/lib/pacman/db.lck
which would tell me if there is a download
however I wanted to know more specifics on the download - progress and time remaining, name of download.
I have also found some GUI programs that use pacman and I was thinking of getting the source code to see if I could use some of that, but haven't found anything useful.
is there a way to find out the specifics about a current download, other than looking at the terminal that the command is running on?
Why overcomplicate things? Just install "screen" via pacman, and start the pacman update inside a screen.. And from your smartphone, use a SSH client to connect to your local machine and access that screen.
You could setup an ssh server on your host machine and connect to it using a terminal emulator on your phone (termux for example) and run whatever commands you like from there. This way you'll be able to view all terminal output from your phone quite seamlessly.

Let me give a quick background of the work I do and then I'll explain the problem I am facing.
I am a software developer with more than 15+ years work experience. My work involves a lot of varied tasks:
data analysis using R, Python
development of web applications using Ruby on Rails, JS, etc.
building models using open source libraries
So far, I have been doing all this in my personal laptop (Ubuntu 18.04) and have faced no issues.
But I would soon need to start using a laptop provided by the organisation that I am working for. This org is not a IT company, it's a public body. They only use Windows (10) and don't provide admin access to anyone. It's very hard to get permission to install any kind of "approved" software. Just to give an example, they refused to install Chrome in my laptop as they wouldn't be able to control the updates.
So here's my problem - what do I do to work peacefully using their laptop? The primary reason I have to use the work laptop is that there are a lot of important documents kept in shared drives that are accessible only in their machines.
I have been looking at options like WSL or Hyper-V. But, before I put in a request to the IT team to get them to agree, I wanted to know a few things:
1) Which among WSL or Hyper-V would be the better approach for setting up the dev environment that I want?
2) IF I get the IT team to install WSL/HV, would I be able to set up everything else without having to go back to them for each software? Is there a way of secure local admin access these options would provide that will ease their concerns?
3) Is there some other way of setting up what I want?
If still applicable and actual I can share my solution:
If you should work on a windows machine where you don’t have administrative privileges, you can very easily make a portable R/Rstudio installation.
Download a recent version of R from the CRAN site and the recent version of RStudio. After download extract RStudio installation exec with 7Zip and copy files from $_OUTDIR to the desired location (in case you making an update, simply overwrite all files, that already exist). Your RStudio executable will be in
your-chosen-directory/bin/rstudio.exe
Then run CRAN-R installation, ignore the warning that you don’t have administrative privileges and go forward until installation will complete. Run RStudio, from the menu
Tools->Global Options
locate where your R installation is located.
If you performing an update (more recent version of R), copy all files from the library subfolder of the old R installation into new, but this time DON’T OVERWRITE! This operation vill preserves the packages you have installed in the previous version of R. After copying update all your packages from the RStudio window (Packages->Update). When the packages update process will end check which packages failed to update (You will see warning messages near them in the RStudio console). Remove these packages (write down names of failed packages and delete corresponding folders from library subfolder). For this, you will need to exit from RStudio. After deletion launch RStudio again and execute the packages install command in the RStudio console:
install.packages(c("package1", "package2", "package3"))
Congratulations, You are ready to go!
How can I open a browser in my VM instance? And how safe/unsafe can this be?
The instance is a Ubuntu 16.04
The only way I know to access the VM is via the SSH button provided by google on the cloud console website.
I want to use it regularly, with pages visually displayed and mouse clicks. (Treat me as a newbie, I'm totally new on Linux and on VMs. I didn't even know there was another way of controlling the browser)
Context:
I need to download a huge amount of data from websites to my virtual machine on Google Compute Engine.
I know there are solutions on the web to transfer files from my machine, but my internet really sucks, it's not feasible.
I also know there are some commands like wget using copied cookies to download some files.
Even though, I feel I'll be needing to use a browser, especially because I want to use a regular Google Drive interface to transfer my files if I need.
Knowing more about this helps, but the question is "how to open a browser and navigate as if I was a regular newbie, with pages displayed and mouse clicks".
Install the desktop
sudo apt-get install ubuntu-desktop
Install VNC server

sudo apt-get install xinit
and then run
startx
this is my first time on such a prestidigious site, so please welcome me by assisting me. I am doing independent development and am primarily a music designer. So that is why I may not sound like a real pro coder but nevertheless truly love creating my music through automative processes.
My present issue is this:
Windows 8.1 Pro
AutoHotkey 1.0.48.5 32bit (running as Admin)
Everytime I attempt to use the command 'RUN' with an .ahk target, I get the expected result except that the .ahk residing folder is opened by MS Explorer. I suspect that something like the fact that AutoHokey is an unsigned app, windows does not want it to run flawlessly. I am now trying a number of Administrative Tool Services disabling, but with no success yet.
RUN C\:XZN\Mecanisms\AnyAHK_script.ahk
;;or
RUN AnyAHK_script.ahk, C\:XZN\Mecanisms
;;or
RUN C\:XZN\Mecanisms\BactchfileLaunchingAboveScript.bat
;;or
RUN AnyAHK_script.ahk, C\:XZN\Mecanisms
Would there be a workaround this at the OS settings level or another way to run/start an .ahk file?
I tried the 'Comspec' approach as well as running an .ahk from within a batchfile, but the .ahk always get intercepted whenever it contains a 'RUN' command requesting an .ahk target.
Thanks.
You are using outdated version of AutoHotkey which is more than 5 years old. Always use AutoHotkey and its documenatation from http://ahkscript.org/ (current uptodate version, new official website)! AutoHotkey and its documentation from autohotkey.com is outdated and you may have some problems using them!
One thing to try if you only have this problem on win 8 is to Enable interaction with administrative programs http://www.autohotkey.com/board/topic/70449-enable-interaction-with-administrative-programs/
That script modifies the executable file's embedded manifest, then creates and installs a self-signed certificate and uses it to sign the file. The executable will not run on any other system, unless you install the certificate used to sign the file.
But lets see some script code that way we have something to test with and can better help you out...
I am trying to use Linux command 'dialog'(1) (/usr/bin/dialog) in my kickstart script (ks.cfg).
However the initial running system does not have it during installation.
It seems even many of the running systems don't have dialog command either.
But I have a DVD with ks.cfg which uses dialog and installs well.
Can someone please figure out how to make it available during installation?
I checked initrd of the DVD I mentioned above which has dialog included; it is not there.
And please, if someone is going to move this question to server fault, can you leave it here for a few days? I wish more people can see this question for I found kickstart related questions don't get answers soon.
Thanks!
I have a Fedora 10 64-bit server where I want to set up a nightly fresh install. The server is an exact clone of our customer's hardware and is used for running acceptance tests.
I would have liked to set this up using a virtual machine, but that's prohibited due to problems we've had with the different video and network drivers on the VM.
Here are the basic steps I need to automate:
Reinstall base Fedora 10
Update to the latest packages
Install additional packages (some of these come from the rpmfusion repository and our own private repository, so the repo files for these need to be added to the configuration)
Restore file system table to include a NAS mount
Restore users and home directories.
I've looked at using Kickstart to do the installation, but it looks as if that will only satisfy the first step above by just answering all the questions that you'd normally answer interactively during installation. Does anyone know of a more suitable tool that I could use ?
Edit: looks like respin could also be very useful here.
You could look at something like
fog - http://www.fogproject.org/
clonezilla - http://clonezilla.org/
Basically these two applications are for the automated, unattended deployment of backup images to machines. They tend to be used in large enterprises but can be used for what you want to achieve.
I have only used clonzilla but fog can apparently run script after a pxe boot install. You could clone the device after all the steps above and just push down the image with a nightly reboot , you could use clonezilla or fog for this, or you could use fog with a script to apply the chances after a clean image has been installed on the server
Kickstart can do more using a %post section
Just wanted to elaborate to #BenBruscella's %post post.
Kickstart has a section where you can include or call up any post-install script to start after the main installation stuff is done.
With this you could easily do your package updates and mounts.
