Recently i needed a Java Array of all Languages, containing some unique id.
I found that ISO 639 is exactly what i needed. The list is offered by the Library of Congress in a CSV like Format (link).
So i parsed this data and thought that maybe someone can use this, either the Java Array or the Code as Example for parsing external data with JavaScript.
Demo:
To fetch the list i used Ben Almans JSONP Proxy and Ben Nadels CSVToArray Function.

The Omnifaces o:cache Component is a useful Tool when trying to speed up you jsf powered website.
But in some situations you need to remove a certain item from the cache or you want to clear the whole cache, while there seems to be a way (Example 4) to remove single items by Key we couldn’t find a ‘official’ way to clear the whole cache.
Here is our Solution to the Problem:
public static boolean removeOmniCacheItem(String key) { Map<string , Object> applicationMap = FacesContext.getCurrentInstance().getExternalContext().getApplicationMap(); if (applicationMap.containsKey(DefaultCacheProvider.DEFAULT_CACHE_PARAM_NAME)) { synchronized (DefaultCacheProvider.class) { if (applicationMap.containsKey(DefaultCacheProvider.DEFAULT_CACHE_PARAM_NAME)) { ((Cache)applicationMap.get(DefaultCacheProvider.DEFAULT_CACHE_PARAM_NAME)).remove(key); return true; } } } return false; } public static boolean clearOmniCache() { Map</string><string , Object> applicationMap = FacesContext.getCurrentInstance().getExternalContext().getApplicationMap(); if (applicationMap.containsKey(DefaultCacheProvider.DEFAULT_CACHE_PARAM_NAME)) { synchronized (DefaultCacheProvider.class) { if (applicationMap.containsKey(DefaultCacheProvider.DEFAULT_CACHE_PARAM_NAME)) { applicationMap.remove(DefaultCacheProvider.DEFAULT_CACHE_PARAM_NAME); return true; } } } return false; } </string> |
At the University (RWTH Aachen) Ahmet and Me are Students at we developed a JSF component which lets a Developers add the often needed comment functionality to a page in a few seconds, which then looks like this (also depending on the chosen Primefaces Theme):
I was looking on the web for a super small and simple class to serialize and deserialize an Object in java.
I needed that to clone/copy an object, but couldn’t find something. I found some bloated librarys, but those were way to heavy for me.
Therefore i made a small class and want to share it with you
These days Youtube was revamped (at least the update arrived in germany too) and i was instantly annoyed by the left aligned design.
I wrote a super small greasemonkey script to fix it, and thought maybe somebody wants it too.
Have fun with it:
Link: The script on Userscripts.com
The Code:
// ==UserScript== // @name Center that damn youtube (for 1920x1080) // @namespace / // @version 0.1 // @description centers youtube.com on screens with resolutin 1920x1080 // @match *youtube.com* // @copyright 2012+, You // @require http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js // ==/UserScript== jQuery('#page-container').css('margin', '0 0 0 300px'); |
Android has the great option to let you Tether your connection via wifi, but as developer you got little to none control over this mechanism.
Therefore i wrote a class to correct this: WifiApManager.
With this class you can check the current Status of the Hotspot, enable/disable it, get/set the current AP configuration and also get the list of currently connected clients.
I also made an example to demonstrate it’s capabilities:
When you want to download a Image from the Web and Display it in Android in a ImageView i encountered two different approaches:
1. Download the Image and Display it:
Drawable DownloadDrawable(String url, String src_name) throws java.io.IOException { return Drawable.createFromStream(((java.io.InputStream) new java.net.URL(url).getContent()), src_name); } [...] try { Drawable drw = DownloadDrawable("http://www.google.de/intl/en_com/images/srpr/logo1w.png", "src") ImageView1.setImageDrawable(drw); } catch (IOException e) { // Something went wrong here } |
I found a nice open-source FTP-Library that can upload files, change the directory etc. (ftpLib.cs was originally written by Jaimon Mathew and modified by Dan Rolander and others).
But it lacks the feature to upload a Directory recursiv, therefore i coded a class with some Extension Methods.
I also made up a small Example:
When i was coding Send2FTP i needed a ZIP-Library that would be able to notify me about the progress while the compression.
After a littlebit research i found DotNetZip a really impressive ZIP Libary for dotNet.
But what i couldn’t find was a good WinForms example for the Save Progress Event. I Also don’t like to deliver my application with alot of dll’s therefore i packed the sources of DotNetZip into the Example.
So i made a small WinForms Example for implementing the SaveProgress Event of the DotNetZip Library and want to share it with you:
We just published the first version of Send2FTP.
Send2FTP is an easy to use FTP Upload Tool it helps you to upload your Files and Folders quickly to your FTP Servers.
