kandi X-RAY | hivemind Summary

hivemind is a Python library. hivemind has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub.

Initially, the steemit.com app was powered exclusively by steemd nodes. It was purely a client-side app without any backend other than a public and permissionless API node. As powerful as this model is, there are two issues: (a) maintaining UI-specific indices/APIs becomes expensive when tightly coupled to critical consensus nodes; and (b) frontend developers must be able to iterate quickly and access data in flexible and creative ways without writing C++. To relieve backend and frontend pressure, non-consensus and frontend-oriented concerns can be decoupled from steemd itself. This (a) allows the consensus node to focus on scalability and reliability, and (b) allows the frontend to maintain its own state layer, allowing for flexibility not feasible otherwise. Specifically, the goal is to completely remove the follow and tags plugins, as well as get_state from the backend node itself, and re-implement them in hive. In doing so, we form the foundational infrastructure on which to implement communities and more. For anything to do with wallets, orders, escrow, keys, recovery, or account history, query SBDS or steemd. Ingests blocks sequentially, processing operations relevant to accounts, post creations/edits/deletes, and custom_json ops for follows, reblogs, and communities. From these we build account and post lookup tables, follow/reblog state, and communities/members data. Built exclusively from raw blocks, it becomes the ground truth for internal state. Hive does not reimplement logic required for deriving payout values, reputation, and other statistics which are much more easily attained from steemd itself in the cache layer. Synchronizes the latest state of posts and users, allowing us to serve discussions and lists of posts with all expected information (title, preview, image, payout, votes, etc) without needing steemd. This layer is first built once the initial core indexing is complete. Incoming blocks trigger cache updates (including recalculation of trending score) for any posts referenced in comment or vote operations. There is a sweep to paid out posts to ensure they are updated in full with their final state. Performs queries against the core and cache tables, merging them into a response in such a way that the frontend will not need to perform any additional calls to steemd itself. The initial API simply mimics steemd's condenser_api for backwards compatibility, but will be extended to leverage new opportunities and simplify application development.

            It depends on the tool used to render your static site on GitHub pages.

            It you are using Jekyll, then since 2016, syntax highlighting for fenced code would be assured by rouge since 2016.

            See this issue

            I was having the problem where Rogue didn't seem to do anything at all (not wrapping code keywords in elements, so there would be nothing to style for the Pygments stylesheet).

            Then I discovered jekyll/jekyll#3641 (comment), removed highlight: rouge from the root of _config.yml and add syntax_highlighter: rouge underneath the kramdown node instead:

            The problem is lstrip removes all the characters you specify that are on the left of the string. 'l' is part of the list of characters you are specifying. lstrip receives a list of characters not a particular string you want to remove. Try this:

            If you already targetting this version, you could try cleaning your project and sync your gradle files.

            facet_wrap on a nudged variable
            Asked 2017-Jan-30 at 05:01

            With lots of overlapping data to show, it can be helpful to jitter points so they can be better identified. For discrete (not necessarily factor) data it can be helpful to offset the entire series slightly. This can now be done quite neatly using ggplot2::position_nudge(). As far as I can tell, that function does not accept NSE variables from the ggplot() call, so (and by all means correct me if I'm wrong) one needs to specify the data source if providing a variable offset from some data structure.

            If, say, we want to nudge a value by an amount dependent on another value, we could do it this way:

            ...

            ANSWER

            Answered 2017-Jan-30 at 05:01

            UPDATE: Based on the discussion in the comments, maybe the best approach is to just add fake data in a location outside the plot area so that all factor levels will have at least one data point. This will result in every point being dodged in every facet. For example:

            First, we'll add data points for all unique values of all variables that will become factors in the plot, but we'll assign them an mpg value of -1, which is outside the plot area of the real data.
