I’ve recently switch to vim-plug, a lightweight Vim plugin manager.

It comes with a little .vimrc snippet which downloads the plugin, but it only works for Unix. I use Vim across all three platforms regularly, so I updated the snippet:

" Download and install vim-plug (cross platform).
if empty(glob(
    \ '$HOME/' . (has('win32') ? 'vimfiles' : '.vim') . '/autoload/plug.vim'))
  execute '!curl -fLo ' .
    \ (has('win32') ? '\%USERPROFILE\%/vimfiles' : '$HOME/.vim') . 
    \ '/autoload/plug.vim --create-dirs ' .
    \ 'https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC

The above should work across all three major OSes, since Windows 10 recently received curl support.

For the past few years I’ve been trying to focus on having more mindful experiences in my life. I find it rewarding to be present in the moment, without my thoughts rushing onto whatever awaits me next.

I present to you the biggest distraction: my phone.

I use to get in touch with people I love. I’m more productive at work because I have access to information on the go. I also use my phone to browse Reddit, YouTube, and every other media outlet imaginable. Even worse, sometimes I just waste time tinkering with the settings or mindlessly browsing through the apps I have installed.

It’s an attention sink.

Nearly a year ago as I was browsing the Google Play Store I bumped into a new launcher: KISS. The tag line caught my attention: “Keep It Simple, Stupid”. I went ahead and downloaded the launcher. I haven’t changed to another launcher since.

Here’s how my home screen looks today:

There’s nothing besides a single search bar. The search bar takes me to the apps I need, web searches I’m interested in, or people I’m trying to reach out to.

It’s simple to use. Start typing an app or a contact name, and the results show up above the search bar:

This simple concept has been responsible for cutting hours upon hours from my phone usage. Opening an app becomes a more deliberate experience, I open my phone with a purpose (granted this purpose might be to kill hours looking at cat videos). There’s no more scrolling through everything I have installed just to find something to stimulate my attention for a few more seconds.

You can download the KISS Launcher for Android from Google Play Store.

Being the unique person I am, I love traveling. Oftentimes I end up getting deep into trying to optimize my packing methods. There are dozens of tools online designed to help with this exact thing (services like Lighterpack or GearGrams). But, being handy with code, I decided to dabble in the subject on my own.

One of the most important things in packing is the overall weight of the pack, and I always want to know what type of things are the heaviest. I also want to be able to run random queries on my data, whatever it is that I’m trying to learn. I want to have an inventory of items (backpacks, clothes, storage solutions) which I can plug in and out of a spreadsheet to see how the resulting picture changes on the go. Working with software as my day job, I’d also like for the solution to be automated whenever possible.

Google Spreadsheets turned out to be the perfect solution, providing the ability to quickly sum up the weight of my things and output insights about the data.

Final Result

Here’s a link to the spreadsheet, I encourage the reader to copy and play around with in anyway you see fit.

Here’s the final result for a multi-day trip I will have for this year. As you can see, my pack weighs around 3 kilograms or a bit over 6 freedom units (not including water). My recently purchased Nintendo Switch is the heaviest item (and it’s worth every gram as it makes flying tolerable), but clothes take up most of the weight:

I use indentation levels to show that some items are contained within other items. This also lets me calculate the absolute and relative weights of a whole container with everything inside of it (see fields labeled “Container” and “Percentage”).

The “Weight” and the “Breakdown” fields indicate absolute and relative item weight respectively, which accounts for quantity of the item (quantity defaults to 1 if not explicitly set). Weight-related fields are color coded from lightest items in green to heaviest items in red.

Categories are used to group items and execute queries on the data and learn insights like these:

There’s a separate sheet where I enter item names, categories, and weights, which I then use to automatically populate values above and autofill item names in the primary sheet:

The Technical Details

I haven’t worked with Google Spreadsheets (or Excel for that matter) a lot in the past, but with an access to clear documentation (and a hundred of web searches later) it was straightforward to get the hang of the it.

I started off by manually populating the final result sheet, manually adjusting formulas for Container/Percentage cells, as I had no idea how I would detect the indentation yet. I like when things look pretty, so I applied conditional formatting rules right away, and the looks of the sheet really haven’t changed throughout the process.

Next, I created an inventory sheet, which I wanted to use as a source of data in the resulting sheet. A few Google searches and some trial & error resulted in a lookup formula:

   INDEX(InventoryCategories, MATCH($B2, InventoryItems, 0)),
     INDEX(InventoryCategories, MATCH($C2, InventoryItems, 0)),
     INDEX(InventoryCategories, MATCH($D2, InventoryItems, 0))

ArrayFormula is necessary in order to create arrays on the fly without printing intermediate results in the spreadsheet. InventoryItems and InventoryCategories are named ranges referring to item names and categories in the inventory sheet. MATCH finds an index of a first occurrence of the item name in the sheet, and retrieves corresponding category name. An item weight is retrieved by the exact same principle.

Trying to find the container weight took a lot more time, and resulted in a lot more headache. Solution for handling indentation in Google Spreadsheets wasn’t as elegant as I would have hoped for, but it got the job done:

           ROW() + IF(
             MATCH(FALSE, ISBLANK($B3:$B), 0),
             MATCH(FALSE, ISBLANK($C3:$C), 0)
           ) - 1

The formula above finds the first non-empty cell in a column. It starts searching from the next row (for example, for an item on a second row, we look at the third row and below). After it knows which row first non-empty cell is in, the formula turns it into a string (column $I contains item weights) and use it as an upper bound of a sum of the weights. Finished formula is a bit longer (it adds sugar to only display the number when needed), and if you’re interested - you can look it up in the spreadsheet.

For example, in the screenshot above, the formula will start looking at cells in a column right after the “Packing cube”. As soon as it finds a non-empty cell (“Nintendo Switch case”), the formula will determine this row to be an upper boundary. The formula then will sum weights starting with a “Packing cube” row, and up to but not including “Nintendo Switch case” row.

The rest involved many small tweaks, adding pretty colors, hiding N/A errors and zeroes, and trying to find the perfect shade for column borders.

And, since you made it this far, here’s how the numbers above look in the real world:

Hopefully you found this useful, or at least somewhat entertaining. There’s a lot of room for improvement, and I aimed to provide a framework and a few basic ideas for building a spreadsheet to accommodate one’s twisted ultralight needs.

I’ve been using Vim for anywhere between 5 and 10 years, and my .vimrc is all grown up. I use {{{1 to annotate folds in my .vimrc, and use zM to close all folds and zR to open all folds (zc, zo, and za respectively close, open, and toggle individual folds). The --- lines are simply cosmetic.

Most plugins above change slightly change daily Vim workflow: the way one navigates files, replaying actions, working with snippets, minor tweaks to editing - and I highly recommend at least skimming through README of plugins you’re interested in so you can incorporate the changes in your workflow.

I have a set of simple defaults I use everywhere, major changes being changing : to ; and moving my leader key to a spacebar. Everything else are tiny quality of life tweaks.

Hope you find this useful and take away a few bits and pieces for your own workflow.

I really like Octopress. It builds on top of Jekyll to address certain rough edges, and provides ready to go lighting fast blogging platform. It’s easily extendible if you know how to code (thanks to a rather clean and well organized code base), and posts are just plain Markdown files.

One issue though - I need to be near a computer to publish and preview the article. This becomes difficult if I’m traveling with, say, a tablet.

I have a low end AWS Lightsail instance I use for writing and publishing, but it’s not always fun to write when SSHing into a server, and I often write offline - making it even more difficult to move files between where I write and where I publish. And managing images is a nightmare. To resolve this, I set up a few directories I use in Dropbox, and wrote a few scripts to move things around when needed.

Here’s a directory structure in Dropbox:

- blog/
  - posts/
    - 2017-11-20-automatic-octopress-publishing.markdown
  - img/
    - input/
      - a-picture-of-a-flower.jpg
    - output/

I put Markdown files in Dropbox/blog/posts/ (and numerous offline editors sync with Dropbox - I’m writing this with StackEdit, and I use iA Writer on my tablet). I add my images to Dropbox/img/input/. I tend to strip metadata from my images and resize them to fit the maximum page width (I don’t really care for high resolution pictures, speed is preferred over ability to zoom into a picture). For this, two tools are needed:

sudo apt-get install imagemagick exiftool

When I’m done writing or want to preview an article, I SSH into my AWS Lightsail instance and run sync.sh, a small script which moves posts to a proper directory, processes images and places them in the desired location, as well as starts Octopress instance (this way I can preview my blog on the AWS Lightsail instance). Contents of sync.sh (don’t forget to chmod +x):

cd $HOME/Dropbox/blog/img/input
mogrify -resize 832x620 -quality 100 -path $HOME/Dropbox/blog/img/output *.jpg
exiftool -all= $HOME/Dropbox/blog/img/output/*.jpg
cp $HOME/Dropbox/blog/posts/*.markdown $HOME/blog/source/_posts
cp $HOME/Dropbox/blog/img/output/*.jpg $HOME/blog/source/images/posts
cd $HOME/blog
rake generate
rake preview

I run the above script every time I want to preview the site. I’m sure it’s easy to set up a daemon to watch for changes in the Dropbox folders, but I don’t see the need for that yet. Also, I just statically resize images to a particular resolution (832x620) since all of the pictures I upload have the same aspect ratio, I’m sure there’s a way to calculate that number on the fly for this script to work with different aspect ratios.

Lastly, when I deployed and committed my changes (still commit and deploy manually out of a habit), I run archive.sh:

mv $HOME/Dropbox/blog/posts/*.markdown $HOME/Dropbox/blog/published
rm $HOME/Dropbox/blog/img/input/*
rm $HOME/Dropbox/blog/img/output/*

It’s not much, but enough to save some manual labor involved in publishing to Octopress.
