  • Grunt: Bower for development and CDN for production - is it possible?

    - by EricC
    For development, I guess it is fine to use a plugin like https://github.com/stephenplusplus/grunt-wiredep But for production I would like to use CDN where such exists. Does it exist a Grunt plugin that goes through the bower.json file and replaces this with a CDN-link from the most popular ones (and if a component is present in more than one CDN, then pick one based on rank-setting or random or something).

  • OpenGL code to render ribbon diagrams for protein

    - by eipxen
    Hey all, I am looking to render ribbon diagrams of proteins using OpenGL and C++. Does anyone know if any open source code for this already exists, or if there are good guides to do this? If not, I'd prefer to figure it out myself ;) but I didn't want to reinvent the wheel, especially if the wheel was free.

  • Limiting the size of a python dictionary

    - by anthony
    I'd like to work with a dict in python, but limit the number of key/value pairs to X. In other words, if the dict is currently storing X key/value pairs and I perform an insertion, I would like one of the existing pairs to be dropped. It would be nice if it was the least recently inserted/accesses key but that's not completely necessary. If this exists in the standard library please save me some time and point it out!

  • How do I set a static bool in another app domain?

    - by Martin
    How do I programatically set the value of a static boolean in another app domain? I'm testing an application where I need to change a bool value. Problem is that the bool value exists as a static instance on a type hosted in another app domain. (I'm doing this for test purposes, it won't be used in production code)

  • Threadpool with pasistant worker instances

    - by Matt Smokey-waters Holmes
    So basically what im trying to do is queue up tasks in a thread pool to be executed as soon as a worker becomes free, i have found various examples of this but in all cases the examples have been setup to use a new Worker instance for each job, i want persistent workers. Im trying to make a ftp backup tool, i have it working but because of the limitations of a single connection it is slow. What i ideally want to do is have a single connection for scanning directories and building up a file list then four workers to download said files. Here is an example of my worker /** * FTP Worker */ public class Worker implements Runnable { protected FTPClient _ftp; // Connection details protected String _host = ""; protected String _user = ""; protected String _pass = ""; // worker status protected boolean _working = false; public Worker(String host, String user, String pass) { this._host = host; this._user = user; this._pass = pass; } // Check if the worker is in use public boolean inUse() { return this._working; } @Override public void run() { this._ftp = new FTPClient(); this._connect(); } // Download a file from the ftp server public boolean download(String base, String path, String file) { this._working = true; boolean outcome = true; //create directory if not exists File pathDir = new File(base + path); if (!pathDir.exists()) { pathDir.mkdirs(); } //download file try { OutputStream output = new FileOutputStream(base + path + file); this._ftp.retrieveFile(file, output); output.close(); } catch (Exception e) { outcome = false; } finally { this._working = false; return outcome; } } // Connect to the server protected boolean _connect() { try { this._ftp.connect(this._host); this._ftp.login(this._user, this._pass); } catch (Exception e) { return false; } return this._ftp.isConnected(); } // Disconnect from the server protected void _disconnect() { try { this._ftp.disconnect(); } catch (Exception e) { /* do nothing */ } } } and basically i want to be able to call Worker.download(...) for each task in a queue whenever a worker becomes available without having to create a new connection to the ftp server for each download Any help would be appreciated as iv'e never used threads before and I'm going round in circles at the moment

  • Paperclip not running tasks but not showing errors

    This is strange. I just did a deploy to a cluster server, and since then, pictures have not been processing. Reading the logs, I usually do not get an error at all, but they never finish.

  • MS SQL Server stored procedure meaning

    - by den-javamaniac
    Hi. I'm developing a simple database architecture in VisualParadigm and lately ran over next code excerpt. IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'getType') AND type in (N'P', N'PC')) DROP PROCEDURE getType; Next goes my stored procedure: CREATE PROCEDURE getType @typeId int AS SELECT * FROM type t WHERE t.type_id = @typeId; Can anyone explain what does it mean? P.S.: It would be great, if you may also check for any syntax errors as I'm totally new to MSSQL and stored procedures.
