Note that whenever you see the python command in this book, you need to use the python3 command instead to make sure you’re using Python 3, not Python 2; they differ significantly enough that you’ll run into trouble trying to run the code in this book using Python 2. If you see a...
This produces peaks of 10 million events per minute, sent as UDP packets without any retry. If you miss, or drop a packet, then it is lost. You have to consume and record those packets as fast as they come to you, with very little buffering in the network adapter. For market data ...
Takes a set of predicates and returns a function f that returns true if all of its composing predicates return a logical true value against all of its arguments, else it returns false.SyntaxFollowing is the syntax.(every-pred p1 p2 .. pn) ...
The culprit seems to be that related fields don't delegateto_pythonto the field they reference so theOtherSubprimary key, aOneToOneField, uses the defaultField.to_pythonwhich is an identity function. This causesthis lineto be falsey becauserel_obj._meta.pk.to_python('1')returns'1'instea...
The distributed log can be seen as the data structure which models the problem of consensus. A log, after all, represents a series of decisions on the “next” value to append. You have to squint a little to see a log in the Paxos family of algorithms, though log-building is their mo...
We have defined X_series the variable to check how the value of x is getting changed. Then in the loop, we have defined the function f at any point(x, a) followed by computing its gradient and then getting the changed values of x which gets computed by subtracting the original value...

When Python detects that there is nothing to be gained by evaluating the rest of a logical expression, it stops its evaluation and does not do the computations in the rest of the logical expression. When the evaluation of a logical expression stops because the overall value is already known,...
I’ve already written about this in my last post so I’m not going to elaborate too much, but it’s important to describe some of the advantages for the Web Platform users this API has over the current alternatives. The Ed25519 algorithm for EdDSA signing and the X25519 function for key...
