Shift Left: How to Turn Security into Review

In the competitive landscape of software business, optimizing processes and leveraging efficiencies can make a significant difference in building a strong pipeline and closing revenue faster. 

  • Apply the DevOps principles of “shifting left” to position security as a differentiator — instead of a hurdle

  • Center security in your sales conversations at every stage to proactively remove roadblocks to revenue

  • Invest in your security story by making it easy for buyers to access security-related information

Vanta helps SaaS businesses of all sizes manage risk and prove security in real time.

1. Tools to Build an AI Second Brain 🧠

I’ve always loved the idea of a second brain after reading Tiago Forte’s “Building a Second Brain”.

It involves segregating your life into 4 main folders:

  • Projects - Ongoing things you are actively doing

  • Areas - Long-term things you are passively doing

  • Resources - Notes and documents you’ve amassed that you need often

  • Archives - Old documents that you don’t need often

But all this organization takes up TOO MUCH time.

What if AI can help?

I found a few AI tools that I think can help you build an AI second brain.

Essentially, you train an AI model with documents about your work and life so that it knows what you know - your second brain!

Here are the tools I found:

2. Find Out What Kind of CAKE (Working Style) You Are! 🍰

Recently, there’s been this VIRAL quiz going around.

It’s called What Cake R U?

It’s a beautiful pixel-art style quiz that will lead you through a job finding village to find out your working style (which cake you are lol).

At the end you’ll receive a result that will profile the way you work and what jobs are suitable for you - a certain type of cake.

Best part is that it’s cute and engaging!

Although the original service has been shut down because it was too viral, you can access the game on Wayback Machine.

Here’s my result:

I’m curious to see what are yours, please reply me with a screenshot of your result!

Here I ask for a differential diagnosis for doctors:

And here’s the full result!

Diagnosing hemophilia and distinguishing it from other bleeding disorders involves a careful evaluation of clinical history, physical examination findings, and specific laboratory tests. Hemophilia is a genetic disorder characterized by the inability to form blood clots properly, leading to prolonged bleeding. It primarily affects males, due to its X-linked recessive inheritance pattern. Here's a structured approach to differential diagnosis, focusing on Hemophilia A and B, the two most common forms:

Initial Clinical Evaluation:

  1. Family History: A detailed family history of bleeding episodes, considering Hemophilia A and B are inherited disorders. Presence of similar issues in male relatives suggests an X-linked pattern.

  2. Bleeding History: Spontaneous bleeding episodes, prolonged bleeding after injuries, surgeries, or dental procedures are key indicators. Hemophilia typically does not cause petechiae or purpura, which are seen in platelet disorders.

  3. Physical Examination: Look for signs of recent or old bleeding episodes, such as hemarthrosis (bleeding into joints), muscle hematomas, or evidence of bleeding in soft tissues.

Laboratory Tests:

  1. Complete Blood Count (CBC): Typically normal in hemophilia, helps exclude other causes of bleeding like thrombocytopenia.

  2. Activated Partial Thromboplastin Time (aPTT): Prolonged in hemophilia due to the deficiency of clotting factors VIII (Hemophilia A) or IX (Hemophilia B). This test screens for the intrinsic and common pathways of coagulation.

  3. Factor Assays: Specific assays to measure the activity of factor VIII and IX. Low levels confirm the diagnosis of Hemophilia A or B, respectively.

  4. Prothrombin Time (PT): Usually normal in hemophilia, helps evaluate the extrinsic and common coagulation pathways.

Differential Diagnosis:

  1. Von Willebrand Disease (vWD): The most common inherited bleeding disorder, affecting both males and females. It can mimic hemophilia but typically shows abnormal platelet function tests and reduced von Willebrand factor levels.

  2. Acquired Hemophilia: Rare, caused by autoantibodies against coagulation factors. Distinguished by a negative family history and a later age of onset.

  3. Other Factor Deficiencies: Deficiencies in other clotting factors (such as factor XI deficiency) can present with similar bleeding tendencies but are identified by specific factor assays.

  4. Platelet Function Disorders: Conditions like Glanzmann thrombasthenia or Bernard-Soulier syndrome present with mucocutaneous bleeding but have normal coagulation tests (PT, aPTT) and abnormal platelet function tests.

Final Diagnosis:

Based on the evaluation, if there is a positive family history of hemophilia, recurrent bleeding episodes, prolonged aPTT, and specific factor assay showing reduced activity of factor VIII or IX, the diagnosis is:

  • Hemophilia A for factor VIII deficiency.

  • Hemophilia B for factor IX deficiency.


Management includes factor replacement therapy to manage and prevent bleeding episodes, avoiding activities with high risk of trauma, and regular follow-ups with a hematologist.

This structured approach to diagnosis emphasizes the importance of a comprehensive clinical evaluation supported by targeted laboratory tests to differentiate hemophilia from other bleeding disorders.
