+I have had my own webpage since 2002 (a-d-c.dk, cs.au.dk/~adc,
+adamsgaard.dk). I use a webpage as a place to keep my contact
+information, software, notes, and research. The previous iteration
+was inspired by the 2015 April 1st retro-version of of gentoo.org,
+bringing back memories of the computing of yesteryear.
+
+The previous backend was a Debian GNU/Linux virtual machine, first
+running at home and then in the cloud. It dynamically served the
+pages with Apache and PHP. However, PHP is notoriously insecure,
+as evident by the extensive list of vulnerabilities[0]. Apache
+is not much better[1].
+
+This weekend I finally made the long-overdue transition to a static
+web page, which improves security and performance. The backend is
+an OpenBSD instance at a cloud provider. There's a plethora of
+free static hosting providers available, but I prefer running and
+maintaining a server myself. The SSL certificate is provided by
+Let's Encrypt. The html front end is generated using Hiltjo
+Posthuma's saait[2] and stagit[3].
+
+I am keeping the retro theme, but all CSS is reduced to a bare
+minimum. The page is entirely free of cookies, javascript, and
+tracking. It is also 100% compatible with terminal browsers.
+
+I moved all of my personal software projects to my own git server
+at https://src.adamsgaard.dk. I do not trust corporations like
+Github (Microsoft), Gitlab, Sourceforce, etc., to always act in the
+users' best interest. However, for the time being I will continue
+to contribute to other software projects on these platforms.</p>
+My git server has a web interface which provides an overview of
+projects, commits, and files. Git access is possible through the
+git (read only), and ssh (r/w) protocols.
+
+Please let me know if you encounter any problems with the new
+infrastructure.

+-- Rationale --
+During the writing phase of an academic paper, common tasks include
+downloading PDFs of publications and getting their references into
+your bibliography. However, I am not a fan of navigating the slow,
+bloated, tracker-filled, and distracting webpages of academic
+journals and publication aggregators. For some reason, many
+publishers decided that clicking the "Download PDF" link should
+redirect the user to an unusable in-browser PDF viewer instead of
+providing the PDF file directly. While the majority of journal
+webpages provide formatted citations for their publications, these
+are inconsistent in style and content.
+
+For these reasons, I constructed a set of shell tools called
+"scholarref" that allow me to perform most of the tasks without
+having to open a web browser. As the title of this post indicates,
+the goal of the toolset is to provide as much functionality a person
+might need during scientific writing without leaving the command
+line. The tools are under continuous development[0]. At present
+I avoid roughly 90% of visits to journal webpages. I hope to get
+to 100% someday.
+
+The "scholarref" design goals are the following:
+
+ - Written as POSIX shell scripts with minimal external
+ dependencies: Ensures maximum flexibility and portability.
+
+ - Aim for simplicity:
+ Fewer lines of code make the programs easier to understand,
+ maintain, and debug.
+
+ - Each tool should do one thing, and do it well:
+ Let the users piece the components together to fit their
+ workflow.
+
+ - Return references in BibTeX format.
+
+DISCLAIMER: The functionality provided by these programs depends
+on communication with third party webpages, which may or may not
+be permitted by law and the terms of service upheld by the third
+parties. What is demonstrated here are examples only. Use of the
+tools is entirely your own responsibility.
+
+
+-- Installation --
+
+ $ git clone git://src.adamsgaard.dk/scholarref
+ $ cd scholarref
+ # make install
+
+The `make install` command may require superuser priviledges to
+install the tools to /usr/local. Prefix with doas(1) or sudo(1),
+whatever is appropriate for the target system.
+
+
+-- The scholarref toolset --
+
+The core functionality is provided by the scripts getdoi, getref,
+and shdl. All programs accept input as command-line arguments or
+from standard input (stdin). The programs come with several OPTIONS,
+and it is encouraged to explore the help text (invoke with option
+-h). The -t option may be of particular interest, since it tunnels
+all communication through Tor via torsocks(1) (if available on the
+system).
+
+- getdoi -
+This tool accepts either names of PDF files or arbitrary search
+queries. If a PDF file name is supplied, getdoi scans the PDF text
+in order to find the first occuring DOI entry, which typically is
+the DOI of the publication itself. If an arbitrary query is supplied,
+the CrossRef API[1] is used to find the DOI of the closest publication
+match. You can supply author names, parts of the title, ORCID,
+journal name, etc. Examples:
+
+ $ getdoi damsgaard2018.pdf
+ 10.1029/2018ms001299
+ $ getdoi 'damsgaard sergienko adcroft advances modeling earth systems'
+ 10.1029/2018ms001299
+
+The -o option will open the resultant DOI in the system web browser.
+
+- getref -
+The getref tool fetches the BibTeX citation for a given DOI from
+doi.org. By default, the journal names and author first names are
+abbreviated, which is what most journals want. I have taken
+abbreviations from the Caltech Library list of Journal Title
+Abbreviations[2]. The getref ruleset of journal-title abbreviations
+is incomplete, and is expanded on a per-need basis. If desired,
+the abbreviation functionality can be disabled. See `getref -h`
+for details.
+
+ $ getref 10.1029/2018ms001299
+ @article{Damsgaard2018,
+ doi = {10.1029/2018ms001299},
+ year = 2018,
+ publisher = {American Geophysical Union ({AGU})},
+ volume = {10},
+ number = {9},
+ pages = {2228--2244},
+ author = {A. Damsgaard and A. Adcroft and O. Sergienko},
+ title = {Application of Discrete Element Methods to Approximate Sea Ice Dynamics},
+ journal = {J. Adv. Mod. Earth Sys.}
+ }
+
+Do not abbreviate journal title with -j option:
+
+ $ getref -j 10.1029/2018ms001299
+ @article{Damsgaard2018,
+ doi = {10.1029/2018ms001299},
+ year = 2018,
+ publisher = {American Geophysical Union ({AGU})},
+ volume = {10},
+ number = {9},
+ pages = {2228--2244},
+ author = {A. Damsgaard and A. Adcroft and O. Sergienko},
+ title = {Application of Discrete Element Methods to Approximate Sea Ice Dynamics},
+ journal = {Journal of Advances in Modeling Earth Systems}
+ }
+
+
+- shdl -
+This tool takes a DOI as input and attempts to download the
+corresponding publication as a PDF through sci-hub[3]. Unfortunately,
+the sci-hub web interface often puts up captias to restrict automated
+downloads. If that's the case, shdl opens the tor browser (if
+installed) or the system web browser in order to manually complete
+the download. Output PDF files are saved in the present working
+directory.
+
+
+-- Usage examples --
+
+The scholarref tools are meant to be chained together. For example,
+if you want a BibTeX reference a search query, simply use UNIX pipes
+to send the getdoi output as input to getref:
+
+ $ getdoi 'damsgaard egholm ice flow dynamics' | getref
+ @article{Damsgaard2016,
+ doi = {10.1002/2016gl071579},
+ year = 2016,
+ publisher = {American Geophysical Union ({AGU})},
+ volume = {43},
+ number = {23},
+ pages = {12,165--12,173},
+ author = {A. Damsgaard and D. L. Egholm and L. H. Beem and S. Tulaczyk and N. K. Larsen and J. A. Piotrowski and M. R. Siegfried},
+ title = {Ice flow dynamics forced by water pressure variations in subglacial granular beds},
+ journal = {Geophys. Res. Lett.}
+ }
+
+The scholarref program itself is an aggregation of the getdoi and
+getref commands. If called with the -a option, the reference is
+directly inserted into the system bibliography. The full path to
+the bibliography file (.bib) is assumed to be set in the $BIB
+environment variable, for instance defined in the user ~/.profile.
+
+ $ echo $BIB
+ /home/ad/articles/own/BIBnew.bib
+ $ scholarref -a 'damsgaard egholm ice flow dynamics'
+ Citation Damsgaard2016 added to /home/ad/articles/own/BIBnew.bib
+
+
+-- Integrating into your favorite $EDITOR --
+
+The scholarref tool is particularly useful if called from within a
+text editor. Below I demonstrate how keyboard bindings can be bound
+in various editors to provide scholarref functionality.
+
+- vi -
+My editor of choice is the plain, old, and simple (n)vi(1). I have
+the following binding in my ~/.exrc, including a trailing space:
+
+ map qr :r !scholarref
+
+The rest of my editor configuration can be found under my dotfiles
+source code repository[4].
+
+- vim -
+You can add the following bindings to ~/.vimrc or ~/.vim/vimrc in
+order to get scholarref functionality within vim(1):
+
+ " insert reference into current buffer
+ nnoremap <leader>r :r !scholarref<space>
+ " append reference into $BIB file
+ nnoremap <leader>R :r !scholarref --add<space>
+
+- vis -
+The vis(1) editor[5] is an interesting combination of modal editing
+and structural regular expressions from the plan9 editor sam(1)[6].
+Add the following binding to ~/.config/vis/visrc.lua:
+
+ vis:map(vis.modes.NORMAL, leader..'r', '< scholarref ')
+
+- emacs -
+Don't know, figure it out yourself.
+
+
+-- Integrating into your pdf viewer --
+
+My PDF viewer of choice is zathura(1)[7], which has a minimal
+graphical user interface and is keyboard-centric. The following
+configuration calls getdoi on the currently open file if I press
+Ctrl-i. The resultant DOI is copied to the clipboard. Similarly,
+Ctrl-s tries to extract the DOI in the same manner, but fetches the
+accompanying reference and adds it directly to the bibliography.
+
+ map <C-i> feedkeys ":exec getdoi --notify --clip '$FILE'<Return>"
+ map <C-s> feedkeys ":exec scholarref --add '$FILE'<Return>"
+
+My full zathura configuration is available here: [8]

+are best sent as patches by e-mail.
