How To Update Gentoo Linux With Ease

Alright, what’s the fuss all about it?? I have been seeing crackpots shedding and muddling with complex ideas to make it a thing to worry about. I am sure, most of them are not even on par with it. And certainly, I don’t know what they are up to with that kind of humdrum.

Here in this post, I shall be able to show you how I personally update my long-standing Gentoo Linux system with ease with very minimal fuss.

Basically, I wrote a few lines of absolutely ordinary shell script to perform the job for me. And it’s been quite some years now that is doing what exactly I wanted it to be done.

Here is the script for your perusal :

#!/usr/bin/env bash

#Syncing with remote repo
eix-sync

#Update the local repo
eix-update

#Actually update the system with fetched in packges
emerge  --verbose --update --deep --newuse --with-bdeps=y  --exclude dev-python/docutils --keep-going @world

if [[ $? -eq 0 ]];then
        notify-send "System has Updated successfully!"
else
        notify-send "Nope, Update is having trouble, please fix"
        exit 1
fi
#Showing what are the packages merge in local system today
genlop --list --date today

#Clean the stale log of previous merge
find /var/log/portage -maxdepth 1 -type f -ls -delete

#Clean the distribution directory to gain disk space
eclean-dist --deep

# It is a custom to rip away the stale stuff from the system after world merge.
emerge --ask --depclean

#Check for security vulnerability by scanning local installed packages.
glsa-check -f --verbose all  && glsa-check -l --verbose all

You see! Nothing overly complex to describe to the people. And, while running it on a dedicated workspace, I do spawn up another terminal where I look at the package merging time in real-time. And the script I use is this :

#!/usr/bin/env bash

while true;do sudo genlop -c ;sleep 30 ;done

it runs in loops to keep going with the merging happening in the other window. Let me pull up an old screenshot of that activity, so you can visualize what is going on:

Because the entire thing is placed on a dedicated workspace(I use I3 Window Manager¹), so, it didn’t interface with other stuff I might be doing on other workspaces.

How To Tweak Linux Kernel Variables On The Fly

Alright, in this post, I am going to show you, how easily you can tweak the Linux Kernel Variables on the fly with ease. The kernel comes with a script folder, and it contains so many of the utilities written by the kernel devs for easy usability. In turn, ordinary people like us can take advantage of those.

Especially, you can take advantage of a script called config which is located in the script folder. And can be used to enable or disable any specific kernel variable while building. I have been using it in my kernel-building script for a long.

In fact, I have an alias set to call it up whenever I needed like this :

And it can be used inside the kernel source tree. If you simply run the script without giving any options, it will tell you, what exactly you need to do.

So, you can see, that you don’t have to prefix the variable you want to enable or disable this script As the help section clearly stated, you can only name the variable without the prefix CONFIG_.

Now, here is the way I have been using it in my script, as stated above, let me show the specific line :

Likewise, you can use it to enable any specific variable you want. One level of convenience.

I3 Window Manager Customizations For My Need

Well, I have expressed my fondness for I3 Window Manger and the associate programs in the past, I3 Window Manager,A Fascinating Journey, which you might take a peek at.

This post is all about a few of my customization entries in the i3-config file, and, certainly, I am not gonna cover everything I did. To know all the customization, you need to look into my i3 config file¹, which is hosted on GitHub.

Git: A Revision Control System Can Be Made Easy And Beautiful

Well, I try to use my extremely limited understanding and knowledge of Git to the fullest potential by borrowing better ideas and works from others. Sometimes, use my crude method(you can see the rough edge written all over it) to get over something complex and mind-bending stuff.

In that quest over the decades, I have curated and adopted so many things related to this bloody good tool to enhance my productivity with it. While I might still not good enough to get over the line, I am constantly trying to learn it from the better people out there.

In this post, I will share a few of my frequently used git operation scripts/commands/processes to make myself comfortable with it every single day. But, why this effort? Because, some parts of gray cells told me many moons ago that, investing in it might be a good thing to happen in computing work. So, the effort behind it, like other software I use, is honest and draining.

Heads up! if the below stuff disappoints you to the highest level, it is your inability to understand my shortcomings, not yours.

Alright, after every sync with the upstream mirror repo I wanted to have a look at, what commits it possesses. Here is a little script that I have embedded in my other(main script to sync with upstream) to show the result once it is finished:

#!/bin/bash

if [ "$1" != "" ];then
        branch="$1"
else
        branch="HEAD"

fi

printf "\n%s%s\n\n" $(git rev-list $branch ^$branch@{1} | wc -l) " commits were added by your last update to $branch:"

git --no-pager log $branch ^$branch@{1} --oneline

..and when it executes, it produces output like this below:

I have snipped the output for the sake of brevity. 🙂

Now, seeing the git log in normally is useful but not fun, to make things more colorful, I have put a little spice to it and it looks like this on the terminal:

…and here is the function for the reason of that above output,

Again, I have made a small function for git stats and it looks like this while running on the repository :

..and I have snipped the output just to avoid the monotone. And the function is like this :

gitstat ()
{
    if [[ -e .git ]]; then
        git log --oneline --stat;
    else
        echo not a git repo.;
    fi
}

This is embedded in the bash initialization file aka dot bashrc , so I can use it throughout the system.

Alright, gitgraph is an alias that shows git commits with graphical decorations, like this

and the alias is like this :

tp_x250_09:32:24_Tue Apr 18: :~>alias | grep gitgraph
alias gitgraph='git log --all --decorate --oneline --graph'

I have been using a program called git-quick-stats¹ , which I have found on Github and it seems it is quite useful. It basically provides a menu on the terminal to select from and it will generate the corresponding output of the git commands. While on the terminal, invoke it like this :

✔ ~/git-linux/emacs [master ↓·1|✔]
09:39 $ git-quick-stats

..and the output of the invocation would look like this :

As you can see, there are various useful options to see. For instance, let me pick one, say number 3 and it will show the last 10 days’ changelog of this repository:

I have snipped the screen capture but you got the idea by looking at the screenshot.

Let me try to select one more option from that menu, so you can see the different output it produces,

I have selected number 11 from that menu and it will show the number of commits per day and it shows like this :

On the leftmost numbers are the commits and the date is besides that number. Pretty useful right?

How to find the last committed hash in a git repository, I have created this :

Neat! See I am happy with my frivolously created stuff.

How to add and commit at once? Let me show you :

It will take one parameter, which is the message within the quote. If not provided it will simply abort the operation.

How to discard changes

It is to take a parameter and do the job of discarding it.

Alright, enough for the time being. If I do something new about it, then I might update this post.

Automation Has To Have Some Purpose That Must Enhance Productivity

What am I telling anew to people?? Every damn shop is doing it and showing the whole world how good they are with big and better tools to accomplish the complex job flawlessly.

What a rosy picture people are sucked into. Anyway, it is not my headache to delve into some wonderland. My automation is trivial in nature, done with readily available tools in the system. ( I am sure, it popped into your head, that is how far you go with that??) and you are not wrong. Because the crackpot’s heads are filled with some idiotic ideas to dish out to hog cheap limelight …..meh.

Now, the rant went away, let me soak you with my frivolous ideas and work. If you get disappointed seeing the below stuff, it is absolutely your shortcoming to see and understand my shortcoming.

The first one is:

Build FFMPEG from the upstream source on Slackware

#!/usr/bin/env bash
#===============================================================================
#
#          FILE: ffmpeg_buid_from_upstream_on_slackware.sh
#
#         USAGE: ./ffmpeg_buid_from_upstream_on_slackware.sh
#
#   DESCRIPTION: This script will build ffmpeg from upstream source
#
#       OPTIONS: ---
#  REQUIREMENTS: rsync x264(this has to be installed beforehand)
#          BUGS: ---
#         NOTES: Shipped package with Slackware might not have all
#        AUTHOR: Bhaskar Chowdhury (https://about.me/unixbhaskar), unixbhaskar@gmail.com
#  ORGANIZATION: Independent
#       CREATED: 08/28/2022 04:17
#      REVISION:  ---
#===============================================================================

set -o nounset                              # Treat unset variables as an error

# Get the latest version from upstream
rsync -avz rsync://mirrors.kernel.org/slackware/slackware-current/source/l/ffmpeg .

ffmpegdir="/root/ffmpeg"

cd "$ffmpegdir" || echo "Nope,not get into it ...aborting"

# Extract out the version numeric from the package name
version=$(find . -name "*.xz" -type f -print | sed -e 's#ffmpeg# #' | sed -e 's#tar.xz# #' | sed -e 's#.$# #'  | sed -e 's#^./-# #')

# Change the permission of the package build script,give exec bit
chmod +x ffmpeg.SlackBuild

echo Building it ....

# This directing the build script to use x264 video codecs
sh -c "X264=yes ./ffmpeg.SlackBuild"

# Checking if the build went alright or not and take decision based on it
if [[ $? -eq 0 ]];then
        echo installing the package.

         sh -c "installpkg  /tmp/ffmpeg-$version-x86_64-1.txz"

else
        echo Build is not ok.cross check it...
fi

Get the damn PDF from the Download folder to the designated pdf folder

Here is what I cooked up for me

#!/usr/bin/env bash

downdir=$HOME/Downloads
bib_source=$HOME/bibliography/pdf_docs/

# inotifywait -m --include "[pdf$]" ${downdir} -e create -e moved_to |
#     while read ${downdit} action file; do
#         notify-send "The file '$file' appeared in directory '${downdir}' via '$action'"
#     done


inotifywait -m ~/Downloads -e create -e moved_to |
while read path action file; do
    #echo "The file '$file' appeared in directory '$path' via '$action'"
    # Check if the file is a PDF or another file type.
    cd $downdir
    if [[ $(head -c 4 "$file") = "%PDF" ]]; then
        notify-send "PDF found - filename: $file"
        mv "$file" $bib_source
    else
        notify-send "NOT A PDF!"
fi
done

Pretty ordinary, but the damn thing works well for me. Basically, keep an eye on Inotifywait (it is a tool, which keeps track of the event in the monitoring path), and once it senses some activity(which was explicitly specified by me) and performs a certain action on it. In this case, move the downloaded pdf file from the download directory to the pdf-docs directory located somewhere else in the filesystem.

Alright, the next one is even simpler:

Sync bibliography file to separate backup location in the file system

#!/usr/bin/env bash

echo Syncing ..wait ..
echo
sudo cp -Rpv /home/bhaskar/bibliography /data/

This little script run periodically from cron.

The next one is,

Sync blogs folder with entry selection, this is a semi-automatic process

#!/usr/bin/env bash

source_dir="/home/bhaskar/blogs/content/articles/2023/"

dest_dir="/home/bhaskar/.emacs.d/OrgFiles/"

backup_dir="/data/blogs/content/articles/2023/"

# inotifywait -m -q -e | while read -r file  | fzf --prompt "select file:"
  # do
  #   # cp "$source_dir" "$dest_dir"
  # done

find "$source_dir" -type f -exec sh -c "basename {}" \; 2>/dev/null | fzf --prompt="Select file:" | xargs -I {} cp "$source_dir/{}" "$dest_dir"

cp -ru "$source_dir" "$backup_dir"

if [ $? == 0 ];then

notify-send "File copied to destination dirs sucessfully"
else
        notify-send "Nope,not done."
fi

I have used an external tool called fzf just for the sake of ease of use. It could have been done without it.

The next one is:

Youtube video script sync with various locations in the file system

#!/usr/bin/env bash

if [ "$title" ]; then

        $(command -v mpv) --ytdl-format=best $url
fi

Again, this is a semi-automatic process. I have to enter the URL by hand and once saved, it gets synced with other places.

How to actually sync with the backup place somewhere else in the file system

#!/usr/bin/env bash

source_path="/home/bhaskar/Videos/"
dest_path="/data/My_YT_Videos/"

$(command -v rsync) -avz --stats --progress "$source_path" "$dest_path"

Alright, the next one is:

Get Youtube stats on terminal

#!/usr/bin/env bash

# This script is to fetch youtube video title and view count and show it on the
# terminal. Presently, only showing latest five videos title and count, but
# that could be change to any number. You need to change the file name to the
# paste command to reflect the change in output.


TIMESTAMP=$(date +%s)
URL="https://youtube.com/c/BhaskarChowdhury/videos"
TITLES="yt-dlp --skip-download --get-title --no-warnings $URL >"$HOME/yt_video_headings""
VIEWS="wget -q -O- ${URL} | grep -oP \"[0-9,]+(?=\sviews)\" | uniq >"$HOME/yt_video_views""
# SPIN="/home/bhaskar/spinner2.sh"

# Checking the timestamp to see when was the last time it was updated. If that
# passed 10 mins then fetch agian otherwise show the last fetched results.

check_youtube_stats () {
# Timestamp
  # {
  #    echo "$TIMESTAMP"
  #  } >"$HOME/.youtube_fetch_timestamp.last"

        echo Hang on! It might take some times to get it...
        echo
            # eval "$SPIN"
            eval "$TITLES"
            eval "$VIEWS"

# if [[ -t 1 ]]
#    then
#      if [[ -f "$HOME/.youtube_fetch_timestamp.last" ]]
#      then
#          LAST=$(cat "$HOME/.youtube_fetch_timestamp.last")
#        DIFFERENCE=$((("$TIMESTAMP" - "$LAST")))
#          if [[ $DIFFERENCE -gt 200 ]]
#            then
          head -n5 "$HOME/yt_video_headings" >"$HOME/latest5_yt_video_title"

          head -n5 "$HOME/yt_video_views" >"$HOME/latest5_yt_video_views"
        # else
        #     echo Too soon to update..
        # fi
        #
# fi
# fi


echo "Views     Title" >"$HOME/yt_video_stats"
paste -d '       ' "$HOME/latest5_yt_video_views" "$HOME/latest5_yt_video_title" >>"$HOME/yt_video_stats"


cat "$HOME/yt_video_stats"

}

check_youtube_stats

Pretty ordinary, honestly. And importantly, it takes some time to get it from there, so you have to leave it there, once invoked.

Notmuch and Mu Are Two Damn Good Tools For Email Searching And Indexing

TL;DR ….I am NOT responsible for your impatience to read till the end.

If and only if, email is closely integrated with your workflow then these tools i.e. Notmuch¹ and Mu² are invaluable for productivity.

Now, let me get you started from a couple of places, where I draw inspiration for running it myself.

One, straight from the mouth of a renowned kernel developer in the LWN³ article.

Two, this Carl Worth,the author of Notmuch describing at linuxconf 2011 Australia video .

Now, once we have to go through the above resources and form a notion about it then from here everything will be downhill, I mean pretty darn simple. I will show you the interface and integration and importantly, how I use it day to day basis.

Let’s, start with the important aspect, how do you access it?? I am ignoring the fact, whoever is reading this post is good enough to know, stat least, how to install packages in their respective Linux distributions and also known how to compile software from source. See, I am making it very clear if you have to have some base to get on with it. Nope, it is not scary, as you might think, if I can grab it, everyone else should be able to do it(knowing my lack of bend of mind).

Once you get over the hurdle of installing the damn thing on your machine(check out the link at the footnotes, which should tell you, how to install it step by step). You can access it from the command line and the very first command you should run is like this :

Now, you can clearly see the explicit options are defined as subcommands to the notmuch binary. I am skipping the first two(setup and new), the former should run the *very first* command after notmuch is installed in the system and it will ask you various questions about a different aspect of your mail management. The latter will simply initialize the NotMuch database to keep a record of the emails you wish to put in.

To see the message in the NotMuch database(assuming you ran,setup first and then new, as explained in the above vignette), you are supposed to run it like this :

..and the result would look like this :

I have just taken out a screenshot from my terminal output of running that search command.

To get specific mail or inbox, you are supposed to tag messages for individuals or mailboxes of a particular type. Likewise, you can reindex the NotMuch database to get a different view of your mail ordering and storage.

You can get all the addresses, which means all the mail id from the header of the sender’s mail header by running :

…and the output would be like this :

Now, interesting aspect, you can run the subcommand dump to get tags associated with a search term like this :

tp_x250_03:58:47_Thu Apr 13: :~>notmuch dump Bhaskar

…and the result would look like this :

Alright, the command line is blazing fast and extremely useful. But, we should be using it within our mail client or at the convenience of our editors. It has got integration with Vim and Emacs.

Emacs has a package called notmuch.el and it provides an interface inside the editor, like this :

..and once select any of the tags(remember I told you that every message has to be tagged in NotMuch to distinguish from each other), pressing t in the above interface and selecting the name will produce output like this in a buffer:

I have selected the Linux kernel tag for the above output. Nice! Right? You can expand the thread on this interface by pressing z on the threaded mail.

There are a lot of options in this NotMuch interface of emacs, you can explore those options at your leisure.

Now, a bit talk about the second software, which is called Mu and is kinda similar to NotMuch. It too has a command line interface, which will allow you to do so many things, You should be familiarized yourself with these commands if you want to use this software. The first thing, if you run man mu and the very first section of it, consists of the command you should be familiar with, for your reference, it looks like this :

tp_x250_04:26:39_Thu Apr 13: :~>mu index
indexing maildir /home/bhaskar/gmail-backup -> store /home/bhaskar/.cache/mu/xapian
/ indexing messages; checked: 14755; updated/new: 0; cleaned-up: 0

As you can see, it has indexed your emails in a certain database of its own. Running the info subcommand will produce the information :

tp_x250_04:29:03_Thu Apr 13: :~>mu info
maildir           : /home/bhaskar/gmail-backup
database-path     : /home/bhaskar/.cache/mu/xapian
schema-version    : 453
max-message-size  : 100000000
batch-size        : 250000
messages in store : 14755
created           : Mon 25 Apr 2022 03:51:37 PM IST
personal-address  : unixbhaskar@gmail.com

Now, if you want to search for somebody’s mail, then you can do so, like this :

tp_x250_04:30:49_Thu Apr 13: :~>mu find Greg

…and it produces output like this :

The above pictures contain emails which are all tagged with Greg.

Mu too has an emacs package and interface, which is called mu4e and it is bloody popular among people. The initial interface will look like this:

and once you select the adjacent keys with the specified options, it will simply bring the specific interface, basically enlisting segregated mails. Let me select one, for instance, I want to see today’s mail then I have to press [bt] in quick succession to get it invoked and the result would be shown like this :

As you can see on the modeline that it was still updating my mail folder. But you got the idea, of how it should look. You can do various actions on them by using all the predefined keys and functions this package provide to get on with it. All it needs investing some time with it(like with any other software).

Finally, I have got NotMuch and Mu integration with my mail client mutt and I access that interface with some mutt macros, just like this :

For Mu to work with mutt inside mutt :

tp_x250_05:00:45_Thu Apr 13: :~>cat .mutt/macros | grep emu
   index \emu "<shell-escape>mu find  --clearlinks --format=links --linksdir=~/.maildir/search date:today   --fields=\" n l \""
tp_x250_05:01:05_Thu Apr 13: :~>cat .mutt/macros | grep emr
   index \emr "<change-folder-readonly>~/.maildir/search" "mu find results"

For NotMuch to work inside mutt :

tp_x250_05:03:49_Thu Apr 13: :~>cat .mutt/macros | grep notmuch
 index \ens  "<enter-command>unset wait_key<enter><shell-escape>~/bin/mutt-notmuch --prompt search<enter><change-folder-readonly>~/.maildir/notmuch_search<enter>"  "search mail (using notmuch)"
 index \ent "<enter-command>unset wait_key<enter><pipe-message>~/bin/mutt-notmuch thread<enter><change-folder-readonly>~/.maildir/notmuch_thread<enter><enter-command>set wait_key<enter>"  "search and reconstruct owning thread (using notmuch)"

Note: that “\e” is to denote the escape key than with two letters, those have to press in quick succession to get the interface.

Here is my absolutely simple and workable NotMuch-config file :

# .notmuch-config - Configuration file for the notmuch mail system
#

#               ----    -------
#               D       draft

#               R       replied
#               S       unread (added when 'S' flag is not present)
#
#       The "notmuch new" command will notice flag changes in filenames
#       and update tags, while the "notmuch tag" and "notmuch restore"
#       commands will notice tag changes and update flags in filenames
#

[maildir]
synchronize_flags=true

Now, here is an ordinary bash script to make the tag with NotMuch and sync my emails with mbsync.:

#!/bin/bash

source ~/.bashrc >/dev/null  2>&1

mail_backup=/home/bhaskar/gmail-backup/

# Clean up the old backup dirs
cd $mail_backup

echo Cleaning old backup dirs ......
find $PWD -type d -name  ".notmuch" -prune -o -name ".notmuch*"  -ls

find $PWD -type d -name ".notmuch" -prune -o -name ".notmuch*"  -exec rm -rf {} \; >/dev/null  2>&1

# Take backup of the existing database
echo Taking backup of the existing database.....

mv /home/bhaskar/gmail-backup/.notmuch{,$(date +'%F_%T')}
find $mail_backup -type d -name ".notmuch*" -newermt $(date '+%F') -ls

# Fetch mails from remote IMAP server to local mail directory
printf "\n\n Getting sync with remote imap server and pull down new mails...\n\n"

mbsync gmail

Bibliography Management In Emacs With BibTeX

Well, on my way to getting better, I have discovered a piece of software in one of my editors(i.e Emacs), and the software is called BibTeX¹ . See, there is little resemblance to the short name with the elaboration of the software it consists of and uses primarily. That means, with bibliography management with tex, you can come up with a more authentic term than my interpretation.

Anyway, while I was managing my bibliographic and note-taking stuff via emacs’ org-mode, that is good enough for the job. But, then why the switch? Because that same stuff can be managed better way with this software.

I have ignored a lot of stuff people write and talk about it. Because those requirements are not required for me. So, I tried to focus on my required thing than what others dish out. Am I missing something by restricting myself to a certain specific thing? Yes, I do. Not yet come the time when I could have to ponder about the other bells and whistles of this specific software.

So, then am I not dishing out half-baked stuff about it?? No, I am not. It fulfills my requirement and that is why I am writing this if somebody wanted to take a cue from it.

Let’s start with the present scenario, then go back to the beginning. Here is what it looks like now :

Okay, a little background, before I opting for to use this software i.e BibTeX, I was happily using another method to keep my books and journals, and notes in separate org files(like everyone else) and pull them up with org-capture-template entries and key binds to insert related info in the specific file.

Likewise, here in this interface, what you are seeing in the picture on top is the main Bibtex interface. It can be used with two precise interfaces inside emacs, those are ivy-BibTeX and helm-BibTeX. I am using helm-BibTeX and it is quite alright for my convenience.

I have got three specific files, which are having a specific name to express the job it is supposed to keep.

bibliography.bib —> is the main bib file where all the BibTeX entries get inducted.

notes.bib –> is the only note-taking file related to the bibliography file.

books.bib —> is for keeping all compiled books entry as pdf

Now, you can see BibTeX needs a dot bib file which should conform to the BibTeX format.

If you scroll down in the main Bibtex interface, you can see those files,

Alright, various things (i.e articles, journals, online, books) have different predefined temples that come with this software. And the default ones are good enough to get along initially. But, once you get comfortable with this,(like we do for every other piece of software we use) then you can churn out your own sadistic requirement with specially designed templates or modify the default one.

Now, how the heck actually does a bib file look likes? Here is a sample

Okay, how do we enter information like the above in the bibliographic file? There is a way to do this in BibTeX and it has a simple key bind, once the bibliographic.bib is open in a buffer, simply type C-c C-b , this will give you a chance to complete the required format for that specific template to choose from. Let me show you, it looks like once you press the key bind

Alright, there are more options if you scroll down that highlighted bar in the minibuffer² for specific requirements. All you have to do, is select the required type in that list and press enter to fuse the template in that bibliography.bib file, simple.

Suppose, in that drop down I have selected book and pressed enter, the template would look like this in the bibliography file as a BibTeX entry :

Now, you can see, the default templates are pretty extensive, you probably do not need all the fields to fill in. The fields starting with ALT or OPT are really optional, which means you can fill them in if you want or have information. But, what are options without those two words, like the first four options, you are supposed to fill in, that is mandatory. Once, you are done with the entry, you are supposed to press C-c C-c to get it formatted for the BibTeX entry. On the way, it also allocates a key for the specific entry to search for that item later. You can modify that entry while on it or access the default chosen one, because, most of the time it shows sensible keys to attach to the document. Finally, you need to save the file with standard C-x C-s and then look at the echo area at the bottom of the screen and it should show Done, (re) loading the bibliography. If the template is not filled properly, and you try to save the file, then it will complain about that action. So, you need to correct that information and then save it, then only the bibliography gets regenerated.

There are currently 87 different commands to manipulate the BibTeX files and I encourage you to go through them at least once, And most of them have shortcut keys attached to them. If something from that command list is not having key bins you can bind it yourself and it is pretty trivial to do so.

Say, you have inducted an entry which supposes to have a pdf attachment, how do you do that? For that operation, you need to place your highlighted cursor on the main Bibtex interface entry and press TAB to get the action menu like this :

So, you can from the above screenshot that various options are available to use for that entry. Choose whatever is required for that entry. If you look closely at the very first screenshot of this page, specifically on the right side between the year and type there are icons for pdf attachments and a note for that specific entry. These icons can be changed through Bibtex variable tweaks from customized menu options. Those are kind of visual indicators.

I can open any entry by highlighting it and pressing enter. If the entry has a pdf attachment, it will go ahead and opens the pdf in the system-wide pdf viewer, in my case it is zathura³ . This is because most of the time I run emacs in tty mode which means in the terminal session. But if you run emacs(like 90 percent of the people do) in GUI mode then you must have pdf=tool to open the pdf inside emacs, which is cool.

For note-taking related to a specific entry, as you saw on the action page, there is an option to edit the note you select by pressing enter, your designated note files get open and allow you to write the note about that entry. Again the predefined note header and properties can be modified via little lisp coding or tweaking the bibtex variables.

let me show you a note-taking screen, the process, if I want to take a note on a specific entry on the main BibTeX entry, then pressing the TAB while the entry is highlighted will put you on the action page like the last screenshot and you have select edit note and the corresponding note file will get open :

See, my cursor is sitting right on the author, and if we go down a little and start writing about that specific subject. Pretty handy, right? And convenient too.

I use citar⁴ to manage to cite specific stuff, as I said almost all the actions have shortcut keys available, if not you can bind one by yourself. I have a key bind to open the cite with key bind C-c t o and it shows like this in minibuffer:

Now, if I select any of the entries from the above screenshot minibuffer, it will simply ask me to create a denote file(which is a way to backlink with other notes) or open the attached URL or pdf. See like this :

Extremely convenient to work around with references and notes. There are way more options than I needed, but the people who are delving into academic papers might need all those. All in all, this software is extremely powerful for resource management.

Also, I sometimes take advantage of org-BibTeX which greatly helps in the citation.

Oh, I have made two videos about the process, you might take a peek at those Emacs BibTeX Adds Convenience Part-1 and Emacs BibTeX Adds Convenience Part-2 .

How To Fix The Damn OpenSSL Version Problem in Slackware

Well, living with a Linux desktop has its own quark and everybody knows about it. In spite of living with it for 23 long years, it still breaks on me and I had to curse and fix it in my local system.

In this case, I was on Slackware Current¹ and made a regular update like every other update to the system and the damn system broke on me, specifically stating that OpenSSL library mismatch problem. As a result, a few of the programs which are bound with it started to not working….irks ..here is an example of it :

[1/1]   Package: openssl11-1.1.1t-x86_64-1.txz
wget: /lib64/libssl.so.1.1: version `OPENSSL_1_1_1' not found (required by
wget)
wget: /lib64/libssl.so.1.1: version `OPENSSL_1_1_0' not found (required by
wget)
wget: /lib64/libcrypto.so.1.1: version `OPENSSL_1_1_0' not found (required by
wget)
`

For this reason, wget, sudo, and many others started complaining about the missing version of the OpenSSL version. A new update to the system bring OpenSSL version 3.1.0. So, it is obviously broken stuff that was built with other versions of it.

After a little bit of head scratching and an internet search leads me to fix the problem for the time being. Here are the steps I took :

Step 1:

Boot into another distro(which I have in other partitions) in this case, I boot into Gentoo.

Step 2

Chooot to a specific partition where Slackware is installed. I have used this script of mine to do the automation to that process, which you can find on GitHub.

Step 3

Open a terminal in the host system, in my case, it is on Gentoo, and get the openssl.1.1.1, and once it is downloaded move or copy that file to /mnt (where I have mount the Slackware partition via my script, see the link in step 2).

Step 4

Once you back into the chroot terminal environment, you can find that openssl.1.1.1 under the root(/) directory.

Step 5

Once you spotted that txz file then you have to run the native Slackware package manager to install that file, like this :

(chroot) root@Gentoo_09:01:12_Sun Apr 09:/ # installpkg openssl11-1.1.1t-x86_64-1.txz
Verifying package openssl11-1.1.1t-x86_64-1.txz.
Installing package openssl11-1.1.1t-x86_64-1.txz:
PACKAGE DESCRIPTION:
# openssl11 (SSL toolkit version 1.1.x)
#
# The OpenSSL certificate management tool and the shared libraries that
# provide various encryption and decryption algorithms and protocols.
#
# This product includes software developed by the OpenSSL Project for
# use in the OpenSSL Toolkit (http://www.openssl112.org). This product
# includes cryptographic software written by Eric Young
# (eay@cryptsoft.com). This product includes software written by Tim
# Hudson (tjh@cryptsoft.com).
#
Executing install script for openssl11-1.1.1t-x86_64-1.txz.
Package openssl11-1.1.1t-x86_64-1.txz installed.
`

Step 6

See, the required version of OpenSSL got installed. Now try to use, one of the apps to see whether it is functioning properly or not. In this case, I tried wget and it works…see…

Choosing The Right Tools And Sticking With It Important For Progress

Well, living with a platform over two decades taught me some stern lessons and most of them were invaluable. In this post, I am going to focus on the technicalities of this aspect. Leave the human interaction(which is equally important) for another take. I am a great proponent of UNIX’s strikingly small utilities¹ always. They are small, useful, and importantly not bulky. Most of my day-to-day work involves taking advantage of those tools and it’s been ages since I took the computer and open platforms as a computing endeavor.

So, to start with while I am sticking with single most platforms throughout my computing life i.e open platforms. Where things change very abrupt pace and keeping up with them sometimes becomes a very daunting task, if that persuasion is not directly impacting your day-to-day life. So, choosing wisely makes a lot of sense and for me, my lack of bend of mind helps me to stick with very few. Primarily, because of my very limited requirement and usability. I am the sort of person not go to hell and is bound to try out all the bleeding edge for no apparent reason. Most of the time my justification for cutting failed on my face, so, I refrained from it.

But, when I do, trying to stick with it as long as possible to make sense of it, in a form that might help me to thrive in life with them. This is the same rationale that insists I choose software from Suckless softwares. The striking thing about their approach to minimalist offerings (mostly ignoring all the hip-hoop-hoopla about their software).

In general, I am not the kinda person to jump the gun too quickly on something, mostly because I have come over the hump. So, I take time to evaluate before coming up with something to say. And importantly hands-on stuff with them.Not just by reading and listening to some renowned people’s thoughts about it.

I have built my stuff(read tools) from there (i.e suckless) offering and sticking with it for some years now. Working with open source can sometimes be really rewarding. But having said that, not everything was hunky-dory, had put in a lot of effort (because of my limited capacity and capability of gray cells), but as usual, that pays rich dividends over time. Moreover, I can derive things from their offering as per my liking and need.

As I mentioned, putting a serious kind of effort to get things going with their software and others’ offering is the norm to get along with them. Sometimes, things do not at all go the prescribed way. Then I have taken deep dive it finds out what is causing that(in a popular term that is called, getting into the rabbit hole), and everybody does that, so I didn’t do anything special. It was more of a requirement fulfillment than anything else. I sometimes disagree with their way of offering things, but it is alright, after all, it is their offering, right? It is up to you to get along and find another way.

You can see here that I built my st terminal² with my requirement and it’s been some years now that I have been using it. Likewise, I have to build a popular application launcher name dmenu³, a little bit of understanding of C language, and importantly knowing patching⁴ and patch⁵ are important to get things lined up for you.

Fortunately, I didn’t have to sweat too much to get over the awkwardness thrown at me by their offering. Most of them were pretty easily discoverable.

Sometimes, the general patching fails me(like many others who use their offering), and would have to do it by hand and hoping for it won’t be too long and clunky and to my surprise, those moments are very short-lived. Because the offering is so minimal that the only way you can enhance it to your liking is by patching various aspects of the specific software to the chosen one. It is a kind of thing you have to bend over it for once(in general).

Investing time in choosing your arsenal is important to get along in the long term view. Something that is popular doesn’t means it has to have better usability than the time-tested and proven ones. Not necessary, that everything comes across as a tool that is bad, but the investigation is of the utmost importance before jumping it and binding it to an important workflow. A few aspects have to consider:

One, the maintenance headache should be less.

Second, the ease of usability.

Third, the smoothness of upgradeability or enhancement.

Fourth, be careful about the licensing strategy.

I don’t think one should look beyond those. Now, comes the question, what happened if the software(the modern tools) is not maintained anymore and you have already inducted it into your workflow, then you are left with the option to fork it and maintain it yourself.

If it is not for individual consumption then working with competent people certainly makes things much better than living with them(tools). At least, you will be sure that if you can’t fix the damn thing, someone else on the team has probably done the things for you. Like it happens in the wild of open source, most of the solutions we get solved, because someone else already bumped into it and taken the pain to solve the issue.

I think I should leave it here for your epistemic endeavor to deal with it.
