Scaling in P2P Kafka vs JMS/MQ

Consider using Kafka as a traditional point-to-point queue (by using just one consumer group). If you have, say 4 partitions of your Kafka topic, you can have a maximum of 4 consumers in your consumer group. Contrast this with a JMS implementation (ActiveMQ, etc.) of a P2P queue. You can add as many consumers as […]

Charging through the prismatic wall?

Theoretically, could a character pass through all 7 layers of the prismatic wall in 1 turn. With enough HP and resistances to handle the damage and high saves (with a lot of luck) would it be possible for this character to just charge straight through and make it to the other side?

Number of LSTM layers needed to learn a certain number of sequences

Theoretically, number of units for a LSTM layer is the number of hidden states or the max length of sequences as per my practice. For example, in Keras: Lstm1 = LSTM(units=MAX_SEQ_LEN, return_sequences=False); However, with lots of sequences to train, should I add more LSTM layers? because increasing MAX_SEQ_LEN is not the way as it doesn’t […]

Close open csv file in scrapy CSV Export Pipeline

I’m attempting to scrape articles on 100 companies, and I want to save the content from the multiple articles to a separate csv file for each company. I have the scraper and a csv export pipeline built, and it works fine, however, the spider opens a new csv file for each company (as it should) […]

Inrush current limiter resistor power dissipation calculation

Theoretically, I have read and understood that during the initial start-up of a circuit, the circuit will draw high current (known as inrush current), so as to charge the capacitors in its direct line to its input voltage value. My questions : But, without performing any sort of testing, is there a way to estimate […]

PHP/SQLite3 form pre-populated does not update database when hitting submit

Situation: On a web page, the end user is asked to provde a database id. They enter the database id, hit submit, and a pre-populated form appears where they can edit any parts of the record that they need to. They then hit submit and, theoretically, the form updates the SQLite3 database and displays the […]

Master-slave flip flop without gate delay?

It seems like a master-slave flipflop always has around a 2-gate delay between the Master and Slave sections of the flip flop. For example: My question is what would happen if, theoretically, there was a zero-delay between the Master and Slave sections of the flip flop? Would the master/slave relationship still work properly, or is […]

Ways to study mathematics.

Recently, I read about a post from a postdoc in mathematics called “Yin Li” who is active in a famous forum called “Zhihu” in China before. He mentioned that as long as we do every single exercise and have a firm understanding in Mathematical Analysis, Linear Algebra, Abstract Algebra and Topology, theoretically, we do not […]
