Software supply chain is an important aspect of secure software development. Recently, we’ve seen an increase in the number of software supply chain attacks. We can protect against some of these attacks by following best practices during the development, and by ensuring the right packages are used. Many of these…

Some of the times we need to use positive or negative infinity as a value. For example, it is used in algorithms where you need to compare the current solution to the best solution so far. Usually at the initiation step, we like to set the cost/value to positive or…

Matplotlib is a great and very capable plotting library for Python. Matplotlib 2.0 made a few changes to their default style that improved the look and feel the graphs. However, we can do more by defining our own settings. This is the setup that I usually use for my plots. plt.style.use('seaborn-poster') plt.style.use('fivethirtyeight') plt.rcParams['axes.edgecolor'] = '#ffffff' plt.rcParams['axes.facecolor'] = '#ffffff' plt.rcParams['figure.facecolor'] = '#ffffff' plt.rcParams['patch.edgecolor'] = '#ffffff' plt.rcParams['patch.facecolor'] = '#ffffff' plt.rcParams['savefig.edgecolor'] = '#ffffff' plt.rcParams['savefig.facecolor'] = '#ffffff' plt.rcParams['xtick.labelsize'] = 16 plt.rcParams['ytick.labelsize'] = 16

Intel Software Guard Extensions (SGX), is a set of security architecture extensions first introduced in the Skylake microarchitecture that enables a Trusted Execution Environment (TEE). It provides an ‘inverse sandbox’, for sensitive programs, and guarantees the integrity and confidentiality of secure computations even from the most privileged malicious software (e.g…
