LaTeX via Images

This is the last thing one should use since images aren’t accessible, and terrible to manipulate. Many platforms, however, do not leave a choice (e.g. Github Markdown). As a stop-gap, use CodeCogs Equation Editor 1 to generate SVGs of equations. Here’s the Bayes’ rule,

Package Conflicts

Often, packages may be loaded transitively and conflict with a previous declaration. To avoid such scenarios, pre-emptively send in package options.

% {<options>}{<package_name>}

A good place is in the preamble right before any other package imports. In this case, any subsequent import of the graphicx package can be done as


which will implicitly also pass the desired option. This is helpful when another package wants to load graphicx with different options. Effectively, this command will append to the options list. This may not always be the best solution but should work for most cases.

Localize Settings

Just wrap everything inside




Wrapping Figure Around Text

% "r" for right, "l" for left

Clean up References

Use rebiber. An example command:

rebiber -i references.bib -r pages,editor,volume,month,url,biburl,address,publisher,bibsource,timestamp,doi


Avoid Inline Splitting

This is often helpful in two-column formats where the inline math can split over multiple lines. To the reader, that looks ugly and distracting. The solution is to simply wrap the equation with curly braces {}.

This inline equation ${a^2 + b^2 = c^2}$ will not split over multiple lines.

Split Long Equations

Inside align environments, use split. {}& for alignment and the usual new line \\ for split points.

a = b + c \\
z^2 = {}&x^2 + \\{}&y^2
\end{split} \\


Fit Oversized Table

To make a table fit automatically across the width, use



In fact, this may just work for anything.

Wrap Text

Cell & \parbox{.5\linewidth}{This is a very long text that will wrap}

Column Spacing


Table Merge Columns

% <column size> (2), <type> (c), <content>
