32,460,593 | 1 | Including the group name in the apply function pandas python <p>Is there away to specify the groupby call to use the group name in the apply lambda function.</p> <p>For instance, if I iterate through groups I can get the group key via the following tuple decomposition:</p> <pre><code>for group_name, subdf in temp_dataframe.groupby(level=0, axis=0): print group_name </code></pre> <p>is there away to get the group name in the apply function, such as:</p> <pre><code>temp_dataframe.groupby(level=0,axis=0).apply(lambda group_name, subdf: foo(group_name, subdf) </code></pre> <p>How can I get the group name as an argument for the apply lambda function?</p> <p>Thanks!</p> |

23,723,500 | 0 | Using dart to create a javascript library <h1>The problem</h1> <p>I'm currently working on a JavaScript library, and in order to reduce the amount of bugs I thought that my library might benefit from using Dart's static typing mechanism. First, because my lib wasn't doing any interop neither with HTML nor with other JavaScript libraries, only pure javascript object manipulation stuff. However I didn't find any info on the net showing how it is possible to build a JS library using dart. So I've tried to do that myself, created initial dart file:</p> <pre class="lang-dart prettyprint-override"><code>library Repo; class Type { final String name; final TypeCategory category; Type(String name, TypeCategory category) : name = name, category = category { category.types[name] = this; } } class TypeCategory { final String name; final Map<String, Type> types = new Map(); TypeCategory(this.name); } class Branch { } class Descriptor { } class TableDescriptor extends Descriptor { TableDescriptor.ctor() { } } class Repo { Descriptor descriptor(String name) { } Branch branch(String name) { } void Merge() { } } main() { return Repo; } </code></pre> <p>Compiled it to JavaScript using dart2js to see how I'm doing:</p> <pre class="lang-javascript prettyprint-override"><code>// Generated by dart2js, the Dart to JavaScript compiler version: 1.3.6. // The code supports the following hooks: // dartPrint(message): // if this function is defined it is called instead of the Dart [print] // method. // // dartMainRunner(main, args): // if this function is defined, the Dart [main] method will not be invoked // directly. Instead, a closure that will invoke [main], and its arguments // [args] is passed to [dartMainRunner].

15,329,446 | 0 | <p>The global <code>cansend()</code> function is generic and can be called from anywhere so I'd probably leave this function as-is unless every invocation of <code>cansend()</code> is from a node class.</p> <p>You could add a <code>cansend()</code> method to your class which uses the stored instance variables as input, rather than having them set as parameters. Furthermore, if you're interested in using properties you could have the <code>operatingMode</code> configured as a property as you suggested.</p> <p>Here's an example refactor:</p> <pre><code>def cansend(nodeID,busID,value): '''sends a CAN frame with a particular value to a specific node''' class node(object): def __init__(self,nodeID,busID,operatingMode): self.nodeID = nodeID self.busID = busID self._operatingMode = operatingMode self.send_can_mode() def send_can_mode(self): """Send current operating mode to node on CAN bus.""" cansend(self.nodeID, self.busID, self._operatingMode) @property def operatingMode(self): """Return current operating mode.""" return self._operatingMode @operatingMode.setter def operatingMode(self, value): """Modify operating mode. Update remote node if mode changes.""" if value == self._operatingMode: return self._operatingMode = value self.send_can_mode() </code></pre> <p>When you want to change modes, you can do <code>node.operatingMode = newMode</code> and if the mode has changed from the previous state, the new mode will be automatically sent.</p> <p>The global <code>cansend()</code> is only called from the <code>send_can_mode()</code> method so you could integrate the global <code>cansend()</code> into your class if desired.</p> |
2,759,655 | 0 | <p>You could use a wrapper class:</p> <pre><code>Class ABWrapper { private AB m_AB; ABWrapper( AB ab ) { m_AB = new AB(); } public void execute() { // Do your stuff, then call original method m_AB.execute(); } } </code></pre> <p>This is a good approach when <code>AB</code> implements an <em>interface</em> (you did not mention that, though). In this case <code>ABWrapper</code> should implement the same interface. When you use a <em>factory</em> or even <em>dependency injection</em> to create your <code>AB</code> instances you can replace them there easily with your wrapper.</p> |

Moreover, the ability to manipulate the stack will bring a LOT of security/consistency issues. This is why manipulating the stack is a bad practice/a security bug even when you can do it (in C, for example). For example,the infamous "buffer overflow" category of security issues spring exactly from this: the ability to insert a "goto", a new stack frame, into the code, so that upon return a malicious payload is executed instead of the legitimate calling function.</p> <p>But then, why would you like to do it? Given a real goal, we could better reason how to do that, and suggest good alternatives</p> |
463,439 | 0 | <p>The standard pattern for implementing events is to use a virtual "OnXxx" method, like this:</p> <pre><code>public event EventHandler OkClick; protected virtual void OnOkClick(EventArgs e) { if (OkClick != null) OkClick(this, e); } </code></pre> <p>Now any time your base control wants to fire the "OkClick" event, it simply calls:</p> <pre><code>OnOkClick(EventArgs.Empty); </code></pre> <p>This means that descendants of your base control can override OnOkClick like this:</p> <pre><code>protected override void OnOkClick(EventArgs e) { // do some stuff before the event is fired base.OnOkClick(e); // do some stuff after the event is fired } </code></pre> <p>Note that the framework design guidelines actually state that you should implement the "OnXxx" method in such a way that the event is fired even if the descendant classes forget to call the base method. I don't really know a good way to do that, and I'm sure most people ignore this guideline.</p> |

29,937,278 | 0 | Design patterns: exposing notifications using a protocol <p>I have got several types of a logic controller class that handle the communication with a remote resource. To do so each class uses an instance of a network controller class that deals with the connection details: connects to a resource, sends data, receives data. The logic controller classes are notified of data changes from the network controller class using notifications. So in my current solution <strong>each logic controller class registers for the notifications and implements specific functions to deal with them differently</strong>.</p> <p>However, if I want to do proper code engineering, I wonder whether it would be <strong>more robust</strong> to use <strong>protocols</strong> and <strong>delegation</strong>.</p> <p>I wonder if I could define which methods the logical controller classes need to implement in order to receive the notification. However I am not sure if this makes sense and is correct because <strong>I do not want inheritance here</strong>. </p> <p>Any suggestion?</p> |
36,108,966 | 0 | <p>You need to put things together differently to accomplish your goal. You can't just replace <code>++</code> with <code>:</code>. Try this:</p> <pre><code>toList t = toListPlus t [] toListPlus :: Tree a -> [a] -> [a] </code></pre> <p><code>toListPlus t xs</code> should produce <code>toList t ++ xs</code>, but implemented with recursive calls to <code>toListPlus</code>, not using <code>++</code> or <code>toList</code>. Let's work through it. The base case is easy:</p> <pre><code>toListPlus Empty xs = xs </code></pre> <p>The recursive case isn't too bad either. We want to convert the left subtree to a list, sticking other stuff on after:</p> <pre><code>toListPlus (Node v l r) xs = toListPlus l ??? </code></pre> <p>What comes after? The root, and then the result of converting the right subtree, and then whatever gets tacked on:</p> <pre><code>toListPlus (Node v l r) xs = toListPlus l (v : toListPlus r xs) </code></pre> <p>This function uses an implicit stack to keep track of the remaining work. This is probably the most efficient way to do it. If you wanted, you could use a zipper-style representation to make the stack explicit.</p> <hr> <p>How does this solution relate to the one leftaroundabout described? Well, they're actually the same. We can see that by shifting the list argument over:</p> <pre><code>toListPlus Empty = \xs -> xs toListPlus (Node v l r) = \xs -> toListPlus l (v : toListPlus r xs) = toListPlus l . (v :) . toListPlus r </code></pre> |

34,358,789 | 0 | <p>You can use a CursorLoader for this. It assumes also that you have a ContentProvider as your data source for the application, which I will not discuss here but you can learn about them in <a href="http://www.vogella.com/tutorials/AndroidSQLite/article.html#contentprovider" rel="nofollow">this post</a> if you want.</p> <p>To sync the database data to your ListView, you will have to do two things:</p> <ul> <li>Create a custom Adapter that implements CursorAdapter</li> <li>Implement a LoaderManager in your Fragment</li> </ul> <p>To implement the LoaderManager just override the three required methods. One is used to setup your Cursor, one will feed the results to your Adapter. From then on, assuming your ContentProvider properly notifies any URIs of changes, you will notice those changes in the Adapter. Here is a snippet of the Loader code:</p> <pre><code>public class AccountsFragment extends Fragment implements LoaderManager.LoaderCallbacks<Cursor>{ private static final int MY_LOADER = 0; @Override public void onActivityCreated() { super.onActivityCreated(); getLoaderManager.initLoader(MY_LOADER, null, this); } @Override public Loader<Cursor> onCreateLoader(int id, Bundle args) { switch(id){ case MY_LOADER: return new CursorLoader( getActivity(), MY_URI, MY_COLUMNS, null, null, null ); default: throw new UnsupportedOperationException("Unknown loader id: " + id); } } @Override public void onLoadFinished(Loader<Cursor> loader, Cursor data) { switch(loader.getId()){ case MY_LOADER: mAdapter.swapCursor(datA); default: throw new UnsupportedOperationException("Unknown loader id: " + loader.getId()); } } @Override public void onLoaderReset(Loader<Cursor> loader) { switch(loader.getId()){ case MY_LOADER: mAdapter.swapCursor(null); break; default: throw new UnsupportedOperationException("Unknown loader id: " + loader.getId()); } } } </code></pre> <p>I learned much of this from a <a href="https://www.udacity.com/course/developing-android-apps--ud853" rel="nofollow">Udacity course</a> that teaches you a lot about Android from the bottom up, and if you are looking for a complete overview I think it is very much worth your time.</p> |

Once you have it tested and working though, it will be easier to use and test because of its simplicity.</p> <p>If you go the remoting route, you can use the IpcChannel instead of the TCP or HTTP channels for a single system communication using Named Pipes. <a href="http://msdn.microsoft.com/en-us/library/4b3scst2.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/4b3scst2.aspx</a>. The problem with this solution is that you'll need to come up with a registry type solution (either in shared memory or some other persistent store) that processes can register their endpoints with. That way, when you're looking for them, you can find a way to query for all the endpoints that are running on the system and you can find what you're looking for. The benefits of going with Remoting are that the serialization and method calling are all pretty straightforward. Also, if you decide to move to multiple machines on a network, you could just flip the switch to use the networking channels instead. The cons are that Remoting can get frustrating unless you clearly separate what are "Remote" calls from what are "Local" calls.</p> <p>I don't know much about WCF, but that also might be worth looking into. Spider sense says that it probably has a more elegant solution to this problem... maybe.</p> <p>Alternatively, you can create a "server" process that is separate from all the other processes and that gets launched (use a system Mutex to make sure more than one isn't launched) to act as a go-between and registration hub for all the other processes.</p> <p>One more thing to look into the Publish-Subscribe model for events (Pub/Sub). This technique helps when you have a listener that is launched before the event source is available, but you don't want to wait to register for the event. The "server" process will handle the event registry to link up the publishers and subscribers.</p> |

8,843,176 | 0 | <p>You might be interested in looking at <a href="http://nrabinowitz.github.com/pjscrape/" rel="nofollow">Pjscrape</a> (disclaimer: this is my project). It's a web-scraping tool built on PhantomJS, giving you full jQuery access to the page in a headless Webkit browser context. It makes it very easy to pull semi-structured data from webpages via the command line, particularly if the page you're scraping has a consistent structure for new elements.</p> <p>For example, you can pull all the course titles from <a href="http://www.ischool.berkeley.edu/courses/catalog" rel="nofollow">this course catalog</a> with the following code:</p> <pre><code>pjs.addScraper( // the page you're scraping 'http://www.ischool.berkeley.edu/courses/catalog', // selector for elements you want to pull text from '.views-row .views-field-title' ); // suppress STDOUT logging pjs.config('log', 'none'); </code></pre> <p>Running this from the command line gives you JSON to STDOUT by default:</p> <pre><code>~> phantomjs /path/to/pjscrape.js my_script.js ["W10. Introduction to Information","24. Freshman Seminar", ...] </code></pre> <p>So it would be pretty simple to run this script on a regular basis, capture the output in a file, and then alert you when the new output doesn't match the previous scrape. You can also write your own scraper functions, so there's a lot of flexibility for more complex scraping if a simple selector won't do the trick.</p> |

This allows you to secure a subset of fields and make them only available to specific users (i.e. it is <strong>not</strong> tied to a role). This security is applied to CRM views as well as forms so it should fit your scenario of having all web-based requests coming via an impersonated user.</p> <p>FLS does have a performance impact. In a high-volume scenario, you might consider moving your "private" attributes to a new entity, relating it to your original public entity and securing access to the private entity separately.</p> |
