The hottest Certificates Substack posts right now

Certificate Authorities can face incidents like misissuance or non-issuance, with misissuances often caused by human error or software bugs.
Baselining Requirements set by the CA/B forum provide rules for dealing with certificate misissuances, including the timeline for revocation.
Entrust's recent incident highlights a misissuance dilemma, where they continued misissuing certificates and refused to follow the proper revocation process, impacting thousands of Extended Validation certificates.

Troubleshooting software issues can involve checking log files and using tools like curl.
The post explores the challenges with installing trading software due to SSL connection and certificate issues.
Detailed logs can help in diagnosing problems, and potential solutions may involve using alternative tools like curl.

Two certificates are being issued for the crash course: Certificate of Attendance for those who attended the entire course, and Certificate of Completion for those who comprehend the basics discussed.
The crash course covers topics like topological and smooth manifolds.
A Quantum Webinar by Dr. Ryuji Takagi from Nanyang Technological University in Singapore is scheduled, presenting their recent ArXiv paper 'Fundamental limits of quantum error mitigation'.

Devices in the Internet of Things (IoT) do not have easy-to-remember identifiers like domain names, affecting traditional authentication methods.
Weaknesses in IoT protocol designs include lack of cryptographically bound data and forward secrecy, and susceptibility to known attacks like Bleichenbacher attack.
Public key encryption used for authentication in IoT can be exploited through various attacks, highlighting the need for stronger security measures.

Understand your tools and use them efficiently. Don't waste time trying to solve a problem in a complex way when a simple solution already exists.
Experiment with your ideas without bias. Test all scenarios, even those that may disprove your initial hypothesis. Failure is part of the research process.
Research and learn from existing studies before diving into a new project. Taking a few minutes to search for prior work can save time, money, and prevent investing in unfruitful ideas.

The group theory crash course is ending with session 20 covering group representations and unitary representations
Certificates of completion will be issued to participants of the nearly year-long journey
A new meetup has been started by a community member to study the applied aspects of quantum computing, emphasizing programming

Certificates of completion were offered to regular attendees of the group theory course who have a baseline knowledge from certain lectures, preparing them for the next course on Lie Groups & Representations.
The upcoming course on Lie Groups & Representations starting in January 2023 does not require completion of the previous crash courses, but having some baseline knowledge in certain areas is recommended for better understanding.
After the Lie Groups & Representations course, there will be a virtual mini school focusing on practical applications such as quantum error correction, classical machine learning, and quantum machine learning.
