Maybe while they are at it they can make some additional $$ improving NYC MTAs sensor network so MTA can know where the trains are!


There's no reason they can't. Public/private partnerships are done all the time.

In Chicago, AT&T got a deal to put small cell towers in places they wouldn't ordinarily be allowed in exchange for building the Office of Emergency Management and Communications a private wireless data network.

In the subways, there was some kind of deal struck with the wireless companies, as well. I don't remember exactly how it worked but it was something like Brand X gets 2-year exclusive on wireless service in the subways if it builds the infrastructure that everyone else can piggyback on later.

It was slightly comical years later when a dozen cities around the world were touting how awesome it was that they were "first" to have wireless service in their subways, while people in Chicago had already been living with the scourge of loud people Facetiming other nobodies about absolutely nothing for everyone to hear. The screeching of the L wheels is preferable.


Context: I am a data analyst who previously was an auditor. JIRA was a game changer for me and I would have loved to have used it during my Audit career. As such, I want an Issue Tracker that works for technical and non-technical individuals.

I would want my Issue tracker to be deeply integrated with the company's Shared File System and Developer tools so all team members have a place to share their work. The Task page would be a place where all the work done could be shared in a clean way and even serve as a quasi-wiki. Like a Jupyter Notebook, I would love to include Markdown and Code along with attachments, analyses, and opinions. Everything would be included, not just the final relevant pieces. Side-analyses stemming from anomalies and potential issues would be hidden but there for those who need them. If something changed in an attachment like an Excel file, these changes would be reflected. Adding dependencies on files and the information contained within them could be linked so that if Account Manager A changes File B, I know that my work on Ticker 123 is now potentially conflicted.

This is something sorely missing from Jira. There's Confluence, but why should you have to create a wiki page to repeat a modified version of what you already have in a ticket.


Some finance books I love (and reread frequently). These books are more about characters and stories, more than traditional non-fiction.

> "not the need to find my place in life at this stage,"

I appreciated this perspective. My primary motivation for pursuing deep work is due to an insecurity with my current ability to be useful to the economy. If this was validated or I solved the mental part of it, I suspect the anxiety would lessen a bit.


Personal circumstances and social pressure vary a lot around the globe, but I dare to suggest that the hardest validation to be won is very often from ourselves, so the latter to me. Take care.


I like to think of myself as having "alternative" priorities :) Thanks a bunch!


I think a key factor in this decision may be the perceived risk of putting huge capital behind a single black box model. I would assume this differs from more ML-heavy quant firms like Two-Sigma, because BlackRock's products generally perform at a huge scale with some central idea behind them. Two-Sigma probably can spread out the same amount of assets across many different black-box models, diversifying and reducing risk through these means. In this case, perhaps only 1 model dictating such a huge chunk of capital was just too much uncertainty?

I have no evidence of the scale and diversification of both these, so evidence would be helpful in refuting the above!


I think so. The ultimate question is who are you going to sue and who is going to sue you if something goes wrong? Imagine having to put your ML researcher on the stand and having him say "I can't say for sure that this or that didn't affect the outcome in a meaningful way"


Business Intelligence Roadmap by Moss and Atre


Some crazy stat exists related to this. Something like Apple making less than 15% of global units while reaping some 80% of the global profits related to said units. In this case, I weigh profits as the best manifestation of the company's position and not units produced.


In 2016:

> BMO Capital Markets analyst Tim Long estimates that Apple accounted for 103.6% of smartphone industry operating profits in the third quarter. Its share is over 100% because other vendors lost money in the business, resulting in Apple having more smartphone profit than the industry netted overall. In the year-earlier period, Apple grabbed 90% of smartphone profits, Long said in a research report Thursday.

My friends think its passion, but really I just forced the medicine down until it became habit, then a permanent fixture, and now is familiar and relaxing. I love learning new things but the "passion" idea is really just me exploring the nuanced depths of a topic I now know a lot about, and that seems to be fulfilling enough that it can masquerade as "passion" to outsiders.


Could you elaborate? Are you eluding to software engineering?


Software engineering (not as a job) for data analytics and data science that help me automate information consumption.
