kandi X-RAY | cloudburst Summary

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

Cloudburst is a low-latency, stateful serverless programming framework built on top of the Anna KVS. Cloudburst enables users to execute compositions of functions at low latency, and the system builds on top of Anna in order to enable stateful computation. Cloudburst is co-deployed with the Anna caching system to achieve low-latency access to shared state, and the system relies on Anna's lattice data structures to resolve conflicting updates to shared state.

Tried to learn from all similar questions but all or most of them are about call of functions by adding () after the name inside JSX. I am not sure why problem is coming in my scenario. I have to put a list of Alerts through conditional JSX where [Alert.js] just export an array;

dashAlerts is a component and you should render it like one. Also note that React component names must being with Uppercase letter.

QFileSystemModel() / QTreeView(): traverse model filesystem tree prior to view expansion

Asked 2018-Jul-14 at 12:48

I wish to create a widget for an app created with PyQt5. I want the user to be able to select any subset of the files within a filesystem hierarchy below a specified directory. I have extended the QFileSystemModel to allow checking the elements in the model roughly following this

example.

I wish the user to be able to modify the checked state of the contents of a directory when the directory is checked - even before the subdirectory has been expanded.

So that this:

...does this 'under the hood' of the collapsed node in the tree view:

The problem I am facing is that the QTreeView - and seemingly the QFileSystemModel - are each, or together optimizing performance by only reporting model items which have been viewed already. Until I manually expand the subdirectories in the View, I cannot traverse the data in the Model.

To illustrate, I have added a print callback, and passed it to my (recursive) tree-traversal routine - to print how many children any index has. (See attached code.) Before I expand a subdir in the Tree View by double-clicking on it, it reports no children: Image 1 reports the following when I click on 'one':

By design QFileSystemModel does not load all the items since that task is very heavy, on the other hand hasChildren() indicates if it has children as subdirectories or files but rowCount() only returns the children that are visible due to design issues, that is discussed in this report.

So you should not use rowCount() but do the task of iterating over the directory using QDirIterator:

Call to undefined method CI_DB_mysqli_result::where() in CodeIgniter

Asked 2017-Dec-29 at 05:47

I am trying to set up a route with CodeIgniter pulling photos by keys 'series' and 'id'. It would follow this logic:

photos/ : returns all of table 'photos' in database.
photos/series : return all photos matching a certain series. 'photos/nature' would return all photos with keys 'series' equaling 'nature'.
photos/series/id : returns single photo. 'photos/nature/1' would return a photo with key 'series' equaling 'nature' and 'id' equaling '1'

calling 'http://localhost/public_html/photos/nature/1' I get the following error:

A PHP Error was encountered
Severity: Error
Message: Call to undefined method CI_DB_mysqli_result::where()

According to error calling where() after get() might cause this issue as alternative move all where() calls before get() or use get_where()

Install cloudburst

You can install Cloudburst's dependencies with pip and use the bash scripts included in this repository to run the system locally. You can find the Cloudburst client in cloudburst/client/client.py. Full documentation on starting a cluster in local mode can be found here; documentation for the Cloudburst client can be found here. An example interaction is modeled below. The CloudburstConnection is the main client interface; when running in local mode, all interaction between the client and server happens on localhost. Users can register functions and execute them. The executions return CloudburstFutures, which can be retrieved asynchronously via the get method. Users can also register DAGs (directed, acylic graphs) of functions, where results from one function will be passed to downstream functions. To run Anna and Cloudburst in cluster mode, you will need to use the cluster management setup, which can be found in the hydro-project/cluster repo. Instructions on how to use the cluster management tools can be found in that repo.
