AndroidPrerequisites

You are using LeeDroid on your HTC Desire and Facebook stopped working. This affects the native app and also FriendStream by HTC. Within the native app you can still update the stream but cannot read any messages. If you delete your native user account and readd it, it will give you an exception like this

( org.bouncycastle.jce.exception.
ExtCertPathValidatorException: IssuerName(OU=Class 3 Public Primary Certification Authority, O="VeriSign, Inc.", CPS Incorp.by Ref. LIABILITY LTD.(c)97 VeriSign, OU=VeriSign International Server CA - Class 3, OU="VeriSign, Inc.", O=VeriSign Trust Network) of signing certificate. [javax.net.ssl.SSLHandshakeException])

Within HTC FriendStream it will give you a „service unavailable“ error.

Even though it’s old, I still like it. The only thing that bothers me about Windows 2003 Server is that annoying shut down event tracking. There are multiple articles about how to use the group policy editor in order to turn it off. In some installations this is not an option as the system folder in the administrative templates is not available.

You can still turn it off via a registry entry. You simply add a new DWORD entry here: HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft\\Windows NT\\Reliability

With the new DWORD value: ShutdownReasonOn (0 = disable; 1 = enable)

Introduction

You want to have a secure connection from your handset to the internet, even when surfing while using an unsecure wireless connection or an untrusted network? This can be done quite easily in case you meet the following preconditions:

  • Your handset is running Android 2.1 or higher
  • It is rooted
  • You own a router that is running an OpenSSH server (this article is using DD-WRT)
  • You have some dynamic IP service to connect to your home router (e. g. Dyn.com)

Introduction

Setting up a track in NetWeaver 7.0 is well documented. You can find it in in Service Marketplace at the CRM installation guides. It is a different story for NetWeaver 7.3. As support for NW 7 is running out, it might be a good idea to set up new projects in a NW 7.3 environment. Therefore we will go through a setup of a track in NW 7.3 and how to connect the track to a run-time system. In this case we will just the NWDI as run-time system. This is not recommended in a live environment. But hey, it’s a sandbox to play with. This tutorial is for people with experience with SAP software and especially the WebChannel application. We will only go through the ERP part. CRM is working accordingly, you just need more SCAs. Please keep this in mind.

The Problem

You have a brand new laptop or wifi card. The little LED that indicates the wifi status behaves differently from what you expect. Either you want it to flash when it’s transmitting data or you dislike the flashing and want it to just light up and stay on. Read on to see what you can do.

The Problem

Backups are important. There is no doubt about this. If you have ever los data due to a harddisk failure or malware, you will most probably agree. But where should you store you backups? I used to have two strategies.

  • I have two identical HDD’s. One for working with, one just for backups
  • The media server (this one) below my TV set also has a copy of the backup but not as current

First of all, I love Android. It’s open, most Applications are free and it’s easy to use. Also it has a wide range of models.

One of my favorite apps is „LBE Privacy Guard“. This app allows you to control „who can do what“. Currently version 2 is the most current one. You can deny access to you location, call logs, etc. For instance: Shazam requires you to agree sending your location. Why? I don’t understand the need for that. This way I just deny the access and it’s blocked. Shazam will just see some fake data and is happy. Also, I want to use the Facebook application but I really don’t want Facebook to see my address book. That’s what they do, they scan your address book. This way I can just block it and Facebook doesn’t see anything but is still happy.

Empty application

Introduction

When writing an application you should consider localizing it. Especially when planning to roll it out in different coutries. The Blackberry OS supports this as a built in feature. You just have to use it. When localizing my first application it gave me a hard time since the Java IDE does some dark magic that I did not expect. Therefore I want to describe what I did and how it works.

At the end of the guide you will also get the chance to download the demo projects. This may give you the ability to play around a bit.
