Back to Postgresql as MongoDB and SQLite fail

After heavier testing, I kept running into SQLite ‘database is locked’ message all the time. It is really frustrating so I resorted back to MongoDB. When I tried reading in my database with pyMongo Python package, I kept getting no results. I would then reset tthe script, then it would work in a wierd way. It seems to be unreliable so I gave up there. This was the first time I cam across this issue. The latest hacking of MongoDB does not help either. I tried Cassandra but they proved to be unreliable. So here we are. Back to Postgres I go. At least it is more reliable.

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at
