kandi X-RAY | qD Summary
qD is an example app for our JavaScript p2p library qOS with cool open source modules such as qD Messages and qD Social and the upcoming qD Vibes, qD Markets, qD News, qD Apps, qD Games and qD Calendar. qD makes it possible to build custom, secure and decentralized social networks in less than 20 days. Our quest network aims to allow the creation and (distributed) completion of quests supported by a feature rich decentralized social network. 0.9.5+ allow to connect qD Social profiles to Twitter without sharing information with Twitter as an additional layer of verification. It is planned to add passive verification for a custom list of external networks to verify the peer identities. 1.0.0+ complies with privacy regulations and can be used for confidential information as a production social network worldwide. We have chosen Angular/Electron as an example environment because we believe it offers the best accessibility for developers coming from any other language/framework. The Quest Network is already being used in Python on PyQt5 and we aim to provide the underlying library in Go and wherever possible in Rust as well. This app is built on qOS which makes use of the Interplanetary Filesystem, IPFS GossipSub and IPFS DAGs.

QUESTION
I have been stuck on this for quite a while. So I thought I'd look it up. But with hours of searching I have come to ask on stack overflow as I am completely stumped.
Basically I am making a Web implementation of Jacks or Better: Video Poker. For some reason I keep getting my kings queen jacks and tens are recognized as the same value. And my full house keeps on being awarded. If my explanation isn't great then go to here or here to find out about the combinations.
If I need to send more code like the style tag I can do so, but I think this is all that is necessary. Any help is appreciated even ways to shorten down my code!

QUESTION
I am learning about c++ and was following a course. A final exercise involves making a program for deck of cards. I have thought of an approach:
I initially tried to do everything with string arrays but realised that it would make more sense to use vectors since. I am now trying to create a std::vector std::string out of my std::string array but with no luck.
I have found some example code online such as: from https://thispointer.com/5-different-ways-to-initialize-a-vector-in-c/
And tried to implement it for my program, however, I cannot get it to work and cant fully understand what is the issue.

QUESTION
I am attempting to determine the OAS of of a callable bond in QuantLib. However, my results are always negative!?
I am wondering if there is some issue in the call schedule, as the bond yield returned from pricing the bond under the Hull White model seems to be reasonable.
Consider the following bond contract:
...ANSWER
Answered 2021-May-05 at 15:21I would set the prepay penalty (call strike) very high so that it is always uneconomic to call, then observe/confirm that your OAS is zero. That would at least validate some of your overall setup. if it passes that test then I would incrementally make one of them economic, and try pricing the European option separately (you could do closed-form with Jamshidian Engine on top of your HW process which is affine) then see if the decompounded value of the option on the dv01 of the bond is close enough to your OAS (assuming the latter is positive). Although if you have a negative OAS with an American set of call dates, it's unlikely that it will become positive with an European call schedule. But these tests may provide some insights.

QUESTION
Recently, I was playing one of my favorites games, and I came accross a problem: This game have a store, and in that store, skins to especific characters are selled, and I'm planning to buy them. There is 34 skins avaliable, and each one costs 1800 credits (the game currency). The only way of earning those credits is buying packs of it with real money.
There is 6 packs, as I show below:
Pack Amount of credits Price 1 600 19.90 2 1200 41.50 3 2670 83.50 4 4920 144.90 5 7560 207.90 6 16000 414.90My first tought was to calculate what was the best way (aka the way of spending less money) to buy any quantity of skins (1 -> 34), but buying N amount of just a single type of pack. So, I wrote this code:
...ANSWER
Answered 2021-Apr-10 at 19:17What you are trying to solve here is a variation of the Knapsack Problem. This means there is no solution in polynomial time possible.
However you can do a few optimizations: In No circumstance will somebody buy pack #2. It is strictly inferior to buying 2 (or 1) pack #1, therefore we can immediately eliminate it for the algorithm so it does not have to waste time on it ;)
