1 dweeks 7 days ago I implemented column hashing @ Postgres synchronization solution

I implemented a hash that takes previous data and current column and the previous hash to produce a hash of the entire database.

This allows us to synchronize with the minimum of data transmissions when I write the synchronizer part which shall rehash all its own data, then retrieve the hash of a binary search of the sorted data.

1 dweeks 8 days ago I implemented document storage in my database project @ Document database backed by keyvalue storage

I spent a few hours working on the remainder of this problem and got documnent retrieval working after finishing save document.

This lets you save and retrieve JSON documents

The document data inserted is also queryable by SQL.

Joins against documents are not yet supported but I plan to implement this.

2 dweeks 7 days ago For 100 threads I managed to get 100 million multithread communication event requests a second, taking 10 nanoseconds to communicate between threads @ Parallel multithreaded actors without locks

Most computers use locks to synchronize, which are very slow. This design is far faster and allows locks to be elided for performance.

I use unscynchronized data structures and achieve 100 million requests a second raw communication performance for a cost of 10 nanoseconds per batch of messages.

2 dweeks 8 days ago Saving JSON documents as SQL @ Document database backed by keyvalue storage

I managed to store a JSON document and I used the SQL inserter to insert the document. In theory the object is queryable by SQL

{ "items": [("name": "item1"), ("name": "item2")], "subobject": {"subobject_key": "value"} }

3 dweeks 7 days ago I updated epollserver to multiplex client sockets across threads. @ Efficient multithreaded server

The idea is that each thread has a ringbuffer, when a socket is accepted, a message is put on the ringbuffer and the thread begins listening to that user.

All the other threads are notified of all the users so they can also echo data to them.

This is efficient as a thread can serve thousands-millions of connections and there are multiple threads.

One problem, which is a generic problem for multithreading is servicing one of multiple kinds of events from one thread. I rely on the fact I am polling a ringbuffer and epoll.

In Ireland there's something called the stock market bar, where prices of … (expand) In Ireland there's something called the stock market bar, where prices of menu items are displayed on a television display, the prices change over time over the night. You can get a drink or food cheaply if you wait for it. There's some algorithm which causes the stock market bar to be entertaining to those who visit. Now, society is composed of many people, and each person is contributing a different thing every second. Some people (consumers) contribute demand for products: water, electricity, food which generates work for others. This is a good thing. We need to represent that demand as part of a wave function. So we need some way of detecting demand for things, digital accounting systems can solve this problem. Such as an app on a smartphone with a button. Or digital NFC keyed shops and workplaces. When everyone is watching television, no work is being done and when the kettle is turned on, the use of electricity goes up. I think some people contribute to a better society than other people. I think essential workers such as delivery drivers, chefs and supermarket logistics are very important people for civilized civilization. They allow the rest of society to function. Unfortunately there is no prestige in these positions and they are not respected by the vast majority of society. Unfortunately, educated people are not willing to do these kinds of jobs due to economic incentives mean they can get more elsewhere. People who have wealth are lazier than people who are forced into labour everyday, economically they produce more wealth but they also do less actual work in the world. Feeding 1000 people in a local area is more fundamentally essential than generating $billions in revenues. I don't want to force everyone to be productive, that's the opposite of my goal. I want the people who do the most work to be rewarded by what they can afford. So even a poor person should deserve the output of 1000 rich persons he provides for. The wave function produces a higher number when work is done and a low number when no work is being done. This is a force multiplier. The demand signal is really valuable, when you're in a restaurant and there is a demand for a certain menu item, you cook more of that kind of item in preparation for the demand. Likewise, a laptop or phone manufacturer produces more of the kind of item that has high demand. The demand signal itself is valuable but nobody is paid for it. People should be paid for their demand signal, as it coordinates society and orchestrates best use of resources for mutual profitability. The wave function is added to what money you do have, and this increases the power of your purchases and acts as additional money in the system.
