Bloomberg Terminal is a widely used financial data provider. Logging in is secured with a password and a 2-FA device. The default option is a small hardware token with a fingerprint sensor. Alternatively, there is an App for Android versions 7.0 and greater. However, there is no such App for Apple devices, however new.

Given the size of Bloomberg and the considerable subscription fees, I imagine that this lack of iPhone support must be a consequence of security issues, rather than a lack of organizational "want".

However, every single bank supports 2FA using the iPhone, so there must be a secure way to accomplish that securely. What are the differences between iOS and Android, has something changed with Android v7, and are there implications to not use an iPhone as 2FA-device?

Hi all,

I'm currently working on my PhD, where I will have to fit a few hundred million high-dimensional curves under somewhat complex constraints. My data - around 3.5 TB - is stored on a Postgresql-Server in my basement.

My current approach is as follows: - Segment the data into chunks and upload to AWS-S3 - Use AWS Lambda to create an AWS Batch Job to run the computation on EC2 spot instances - Store result on S3 and fetch

While that works like a charm, it also burns through my grad student budget like a wildfire, so I am looking for less cost-prohibitive ways of running that computation.

I have considered either running my tasks on EC2-comparable instances with another (cheaper) provider, since the AWS Batch functionality is mostly convenient, but I don't really need the flexibility. I know exactly which results I need, since my data set is already complete. However, I don't understand enough about cloud computing to exactly quantify how many requests or hours of computing I need on what type of processor.

Alternatively, I might just buy more computers, and heat my flat with those for a few months, before selling them again. Issues here are the high upfront cost, but it would give me cost safety over time. I also have no idea how long my computation would need.

How would you approach this problem?
