This is the same as an older thread, but I didn&#x27;t comment in the last one, so I thought I&#x27;d comment here.<p>I was a technical reviewer on Node Security from Packt, and it was an interesting experience, so I thought I&#x27;d highlight a few things for those who have criticised the quality of Packt books.<p>- Reviewers are unpaid, I&#x27;m not sure if this is normal. I was happy to do it unpaid as experience that I could talk about with future employers. The only &#x27;pay&#x27; is a copy of the book, and one other from the library.<p>- I was found and asked to be a reviewer, but I was quite surprised given my lack of experience. I was also surprised at the lack of experience of the author. I felt I was able to do my job as a reviewer, and would have declined otherwise, but I perhaps they should be finding some more experienced people.<p>- Node Security is one of their shorter books, most are either several hundred pages and ~$30-40, or about 100 pages and $20. During the review process I highlighted that I felt the book did not contain enough content for a $20 book, lots of it was quite practical stuff that could have been found by reading some READMEs on GitHub repos for the libraries it talked about.<p>- I noticed that much of the advice in the book was around deployment of Node.js applications, and I suggested an extra chapter specifically about configuring secure deployments, perhaps covering nginx reverse proxying, etc, I felt that this would really improve the overall quality of the book, the focus of each chapter, and ultimately I thought it would make the book well worth the $20. Unfortunately they declined to do this. I&#x27;m not sure why, and I&#x27;m not sure what my role as a technical reviewer was for because of this. I found some minor issues in the security theory descriptions, and a few errors in example code, as well as making a few suggestions for how bits could be worded better, but it seemed they weren&#x27;t keen on any major suggestions.<p>I&#x27;m not sure whether I&#x27;d buy books from Packt, I&#x27;d probably have to evaluate them on an individual basis, but I felt there could have been better selection of authors and reviewers, and that they should have been more open to changes proposed by the reviewers.

I&#x27;ve read some great books from Packt, this wasn&#x27;t really one of them. When the first thread was on HN, I got excited because I love Python and had been looking into starting some investments. Namely, I want to implement a low-risk, low-frequency automated trade strategy. Naively, I assumed this book would be for people who knew Python and were interested in learning finance, but it was the opposite. A lot of concepts were thrown out there with little to no explanation. I gave up reading it until I actually know finance, and can use it as a cookbook.<p>The code in the book is also shoddy. I don&#x27;t have it with me, but two examples come to mind. I didn&#x27;t run any of the examples, but eyeballing them I some of them wouldn&#x27;t run because of syntax errors -- rather unfortunate for a beginner&#x27;s text. The section of naming conventions. To write a program using a financial expression like P(1+r)<i></i>n (exponential growth&#x2F;decay), the book recommends against using confusing variables like p... in favor of P. P stands for Principal in this case, and I doubt many of you knew that off hand.<p>For those looking to do finance in Python, I recommend looking into QuantLib[1]. I&#x27;m also watching a series of videos from the University of Michigan&#x27;s online Intro to Finance class on YouTube[2]; however I realized a few days ago that they&#x27;re probably pirated. That makes me feel bad, but its still a good reference.<p>If any quants on HN have some better book recs, they would be strongly appreciated.<p>Edited to add; To be fair, I haven&#x27;t really touched the section on Monte Carlo simulations, which seems to be the bulk of the value.<p>[1] quantlib.org<p>[2] <a href="https://www.youtube.com/watch?v=pQeZqn-8yM8&amp;list=PL07D40483B1BE4B4C&amp;index=1" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pQeZqn-8yM8&amp;list=PL07D40483B...</a>

I have the book, though haven&#x27;t spent much time with it yet. Initial impression was that it&#x27;s quite brisk. You&#x27;ll get a couple paragraphs on a new concept and then a code snippet to demostrate. You&#x27;d need to compliment it with deep study of the actual concepts.<p>Still, sometimes breadth is better than depth.
