5 min readWhen choosing a webcam that works well in low light for Zoom meetings, you should consider factors such as sensor quality, aperture size, and the presence of features like low-light correction and HDR support. Webcams with high-quality sensors are more adept at capturing clear images in dim environments. Additionally, cameras with larger apertures allow more light to enter, which helps improve image quality in low light.

7 min readIn LaTeX, equations and subsections are typically numbered automatically by the document class and the use of specific environments or commands. To identify the counters used for equations, you can look at the equation environment or other math environments like align or gather, which generate equation numbers. These counters are usually labeled sequentially as Equation 1, Equation 2, etc., unless otherwise specified.

6 min readTo change the font size on part of a page in LaTeX, you can use font size commands within a group enclosed by curly braces to limit the scope of the size change. For example, use \small{} or \large{} to make text smaller or larger, respectively. Alternatively, use \begin{size}{} with a specific size such as \begin{small}...\end{small} to change the font size of a specific portion.

4 min readWhen looking for a good budget web camera for Zoom, there are several important factors to consider to ensure quality and performance without breaking the bank. A good budget webcam should offer at least 720p HD video resolution, though 1080p is preferable for a clearer picture. It should also have decent autofocus and a good-quality microphone for clear audio transmission. Plug-and-play USB connectivity is convenient for easy setup without needing additional software.

7 min readTo highlight "what's new" between two LaTeX documents, you can use a tool called latexdiff. This utility compares two versions of a LaTeX document and marks changes, such as additions, deletions, and modifications. To use latexdiff, first ensure it's installed on your system. Then, run it from the command line with the two LaTeX files you want to compare, typically the old and the new version. The tool generates a new LaTeX file with markup indicating the differences.

5 min readTo execute a shell script from LaTeX, you can utilize the shell-escape option available in most LaTeX compilers. This allows the LaTeX document to execute shell commands during the compilation process. Firstly, ensure that your LaTeX compiler supports and has enabled shell-escape, which may involve adding a flag like --shell-escape or -shell-escape in your compilation command. Within your LaTeX document, you can use the \write18 command to execute shell scripts. For example, \immediate\write18{.

This can be particularly beneficial for professionals who need to present a polished and clear image, such as educators, entrepreneurs, or creative professionals. The enhanced resolution is also useful for group meetings where multiple people may be in the frame, as it can capture details more accurately.

You'll first need to decide on the appearance and functionality of your new symbol. If it requires a simple modification of an existing symbol or a combination of existing symbols, you can use the \newcommand or \DeclareMathOperator to define your own math symbol.

9 min readImproving the quality of your webcam for Zoom calls involves several steps focused on both hardware and software aspects. Firstly, ensure that your physical environment is well-lit with natural light, avoiding strong backlighting which can create silhouettes. A desk lamp or ring light can also provide consistent and flattering illumination. Ensure that your camera lens is clean, as smudges or dirt can significantly reduce image quality.
