Android & WiFi information, Wifimanager + Wifiinfo

        WifiManager myWifiMananger = (WifiManager) getSystemService(WIFI_SERVICE);

        WifiInfo myNetInfo = myWifiMananger.getConnectionInfo();

        showIp.append(changeIp(myNetInfo.getIpAddress()) + " \n");

        showIp.append(myNetInfo.getSSID() + " ");

        List<ScanResult> scanList = myWifiMananger.getScanResults();

        for(ScanResult element : scanList){

         showIp.append(element.SSID + " Level: " + element.level + " freq : " + element.frequency + " Cap: " + element.capabilities + "\n");

        }
//DONT forget that the getIpAddress returns an int value. Convert it to string :
public String changeIp(int ipAddress){

     return String.format("%d.%d.%d.%d",

       (ipAddress & 0xff),

       (ipAddress >> 8 & 0xff),

       (ipAddress >> 16 & 0xff),

       (ipAddress >> 24 & 0xff));

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

  <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

Outlook backup

The following procedure is valid only for Microsoft Office Outlook 2007. You can determine which version you are using by opening Outlook and clicking on Help > About Microsoft Outlook.

The Personal Folder file (.pst / PST) is the place where Outlook stores its data (when you're using Outlook without Microsoft® Exchange Server). Each Personal Folder file contains all of your Outlook folders, including the Inbox, Calendar, and Contacts. You may have a single .pst file (usually called "Internet Folders" or "Personal Folders" in your Folder List), and you may also have an additional .pst file that you use to archive messages (named "Archive Folders"). By backing up these PST files you will be backing up all your Outlook information.

In previous versions of Outlook, it was difficult to locate the folder containing the personal folder files. Developers have made this task much easier in Outlook 2007.

There are two ways to access the location of your data files. In the main menu, you can either click File > Data File Management... or Tools > Account Settings...

If not already selected, click on the "Data Files" tab. You may have a single data file or multiple data files. These "Data Files" are where you store your email messages, calendar, tasks and other items.


Highlight the data file that you are interested in backing up and click on the "Open Folder..." icon. Clicking on this icon will automatically launch Windows Explorer and take you to the location where this data file is stored.

Within the folder you should find an outlook.pst file . Burn this file to a CDROM disk or other backup source. If you archive your email, be sure to backup the archive.pst file as well. Prior to backing up these files, Outlook will need to be closed.
The table below lists key Outlook files that you may want to back up in addition to your Personal Folder(s). You will need to completely exit Outlook prior to copying these files. Depending upon your configuration some or all of these files may be present in your Outlook directory.

Ignite Oslo, Rapid Prototyping

On Thursday I hold one of the most difficult presentations of my life. I was representing Robotica Osloensis, a student community which I am deputy chairman of, at Ignite Oslo. I talked about Rapid Prototyping which we use as our main method at Robotica in our projects. Ignite is a style of presentation where participants are given five minutes to speak on a subject accompanied by 20 slides. Each slide is displayed for 15 seconds, and slides are automatically advanced. The Ignite format is similar to Pecha Kucha, which features 20 slides displayed for 20 seconds each.

The Ignite Oslo was a very nice event. They had 5 minutes presentations about different topics(list over topics) which were very interesting. Presentations about art, film making, music composition with applications on iPad, 3D printing, air balloons and fashion, etc. It was pretty stressful when it came to my turn. The whole idea of 15 seconds intervals and having a lot to say about a subject that actually belongs to the nerd world made me very nervous. Thanks to my friends Magnus Lange and Ole Jacob, who helped me both about the content and preparing in advance for the presentation, I was well prepared. Also I should thank my friends who came there to support me when I was actually holding the presentation. My presentation can be downloaded by clicking here.

Category 5, cable standard

Category 5 cable (Cat 5) is a twisted pair high signal integrity cable type. This type of cable is used in structured cabling for computer networks such as Ethernet and ATM, and is also used to carry many other signals such as telephonyand video. Most Category 5 cables are unshielded, relying on the twisted pair design for noise rejection. Category 5 has been superseded by the Category 5e specification.


I usually use these cables in my robotic projects as well, as they come in a well packaged easy way and one can easily setup one protocol to use one color for one kind of signal :-)
