pmb | An Open Source Predicition Market using Parimutuel betting

kandi X-RAY | pmb Summary
Meant to create a Pari-mutuel Betting system where people can place bets and odds are determined by the size of other bets. The winners split the total pot based on the size of their bets on the winning outcome. Users create questions with specific possible outcomes. The outcomes should be mutually exclusive and cover the complete possible set of outcomes. Users can then place bets on those outcomes. As they bet the likelihood of different outcomes will become clear and may change over time. Once the event has happened and the question is answered, a moderator should close the question which will distribute the funds appropriately and prevent any new bets on the question. By default, comments are enabled on question nodes. Discussions on questions should be encouraged: * Is this a well stated question? * Has the question been decided meaning it needs to be closed? * General banter on the topic could be insightful: "I bet this way because…" "Here is some research/evidence that could be useful.". Pari-mutuel betting is great for simplicity and short-term bets. It’s less great for bets with a long horizon because people have to keep their money in the position until the event happens in order to win. The drawbacks here are that people expect interest if their money is tied up AND that there’s no ability to benefit from short-term movements in the odds.

Let's say I have this text:
...ANSWER
Answered 2021-May-04 at 05:01With your shown samples, could you please try following. Using Python's re
library here to fetch the results. Firstly using findall
to fetch all values from given string var where (.*?)\s+\((?=P[A-Z])
will catch everything which is having P and a capital letter after it, then creating a list lst. Later using substitute function to substitute everything non-spacing things followed by spaces 1st occurrences with NULL to get exact values.

I implemented a Cuda matrix multiplication solely in C which successfully runs. Now I am trying to shift the Matrix initialization to numpy and use Python's ctypes
library to execute the c code. It seems like the array with the pointer does not contain the multiplied values. I am not quite sure where the problem lies, but already in the CUDA code - even after calling the Kernel method and loading back the values from device to host, values are still zeroes.
The CUDA code:

Answered 2020-May-13 at 05:24GitHub itself, through its GFM (GitHub Flavored Markdown Spec) does not support Katex
You would need for your GitHub repositories to be a GitHub Pages project in order to include for instance a Jekyll plugin like linjer/jekyll-katex
, in order for those pages to represent a Katex section properly.

. Grouped by 'V1', create a frequency column 'n', then groupedd by 'V2' and 'n' along with 'V1', get the frequency again ('n1'), divide the 'n1' by 'n' after ungroup
ing, and then convert the 'long' format to 'wide' format with pivot_wider

QUESTION
I understand this is a new feature being worked on for GHC's Hadrian build system, so the workflow might be advanced, oddly specific, or still evolving. I read these so far:
It sounds like it should work for my use case: a domain-specific language for bioinformatics that would benefit greatly from caching comparisons between large genomes. I would be happy working from a basic minimal example or description of where to look. But I've included more details about my program too in case they make it easier...
The shortcut interpreter builds lots of artifacts with names derived from hashes of their inputs (somewhat Nix-like), and theoretically they should be portable across machines or even operating systems. A small program run might generate files + symlinks like this:
...ANSWER
Answered 2019-Dec-14 at 17:31I think there's a confusion here that newCache
and newCacheIO
are involved with the Cloud Shake feature. They aren't - in fact, newCache
happens to be one of the things that has no impact on the cloud cache (coincidentally, rather than because of the Cache
in the name). I see no reason your use case shouldn't work with Cloud Shake.
The exception /home/jefdaj/shortcut/sharedir/.shake.cache/2faae061b9976bed/0x134125AC: getPermissions:getFileStatus: does not exist (No such file or directory)
seems to imply that Shake has recorded that the above file is in the cache, and can be used to satisfy the file. So the question is where did the file go? Is it possible when you cleaned the files that they deleted the files from the cache too? Shake can be run with both --share-copy
and --share-symlink
- I'd recommend the former to ensure there is less action-at-a-distance, which might also explain what is deleting the files. I'd also recommend using Shake HEAD, as there are some fixes that haven't yet been released.
If that still doesn't work, perhaps raise a ticket on the Shake GitHub?
