DisableServerCheck for Mac Lync Client

Ramon van Bruggen — Thu, 10 Mai 2012 11:33:00 +0000

Ik gebruik nu al enige tijd mijn MacBook Pro voor mijn dagelijkse werkzaamheden, stap voor stap ga ik steeds meer over van good old Windows naar Mac OSX. Vandaag heb ik voor mijn werk Microsoft Lync geïnstalleerd. Helaas liep ik hier tegen hetzelfde probleem aan als bij de Windows versie, namelijk dat mijn werkgeven nog geen Lync compatible server gebruikt, maar ook hier is net als op het Microsoft Windows platform een weg omheen

Wat je moet doen is dezelfde registry keys toevoegen als in Windows, alleen heeft de Mac geen registry en zal je daarom de aanpassingen in een Plist bestand moeten worden gemaakt. Dit bestand heet MicrosoftLyncRegistrationDB.xxx.plist en kan worden gevonden in: ~/Library/Preferences/ByHost. Het makelijkst kun je naar de “Finder” gaan en daar boven in het menu Go –> Goto Folder… kiezen. Open het bestand en zoek in dat bestand naar de entry: “Current_Version”. Onder Current_Version moet je een voor een de volgende keys toevoegen:

hkey_current_user\
hkey_current_user\software\
hkey_current_user\software\policies\
hkey_current_user\software\policies\microsoft\
hkey_current_user\software\policies\microsoft\communicator\
hkey_current_user\software\policies\microsoft\communicator\disableservercheck

De waarde van elke key is “<>” van het type string. Als laatste voor de disableservercheck vlag zet je het type op Number en de waarde op 1.

Als alles goed is zou het er als volgt uit moeten zien:

Converteer tussen Web Mercator en WGS84 Geographic coordinaten

Ramon van Bruggen — Fri, 06 Apr 2012 09:37:17 +0000

Ik ben nu net een keer te vaak op zoek geweest naar functies om WGS84 (4326) coordinaten te converteren naar Web Mercator (102100) en andersom. Daarom heb ik ze hieronder neergezet voor iedereen die ze ook vaker nodig heeft. De functies komen van ESRI:

private void ToGeographic(ref double mercatorX_lon, ref double mercatorY_lat)
{
    if (Math.Abs(mercatorX_lon) < 180 && Math.Abs(mercatorY_lat) < 90)
        return;

    if ((Math.Abs(mercatorX_lon) > 20037508.3427892) || (Math.Abs(mercatorY_lat) > 20037508.3427892))
        return;

    double x = mercatorX_lon;
    double y = mercatorY_lat;
    double num3 = x / 6378137.0;
    double num4 = num3 * 57.295779513082323;
    double num5 = Math.Floor((double)((num4 + 180.0) / 360.0));
    double num6 = num4 - (num5 * 360.0);
    double num7 = 1.5707963267948966 - (2.0 * Math.Atan(Math.Exp((-1.0 * y) / 6378137.0)));
    mercatorX_lon = num6;
    mercatorY_lat = num7 * 57.295779513082323;
}

private void ToWebMercator(ref double mercatorX_lon, ref double mercatorY_lat)
{
    if ((Math.Abs(mercatorX_lon) > 180 || Math.Abs(mercatorY_lat) > 90))
        return;

    double num = mercatorX_lon * 0.017453292519943295;
    double x = 6378137.0 * num;
    double a = mercatorY_lat * 0.017453292519943295;

    mercatorX_lon = x;
    mercatorY_lat = 3189068.5 * Math.Log((1.0 + Math.Sin(a)) / (1.0 - Math.Sin(a)));

Lang geleden..

Ramon van Bruggen — Wed, 04 Apr 2012 23:35:00 +0000

Zo en dan is het ineens zomaar weer een tijd geleden sinds mijn laatste bericht. Ik ben net zoals iedereen altijd zegt als je hem vraagt hoe het met hem gaat, druk, druk, druk..

Voor mijn werk ben ik de laatste tijd nogal druk geweest met een aantal applicatie die waren gemaakt in ASP.NET om te zetten naar Silverlight. Erg leuk! Verder ben ik al enige tijd bezig met het ontwikkelen van Apps voor de iPhone en iPad, aangezien ik een Microsoft ontwikkelaar ben heb ik besloten om dit te doen in C# met behulp van MonoTouch en MonoDevelop. Ik zal proberen om de aankomende tijd wat te posten over mijn ervaringen met het maken van iOS Apps met Mono.

Ohja dan nog een laatste dingetje, een aantal van mijn bezoekers zal deze post niet kunnen lezen omdat zoals je wellicht hebt gezien deze niet in het Engels is. Ik heb hiervoor gekozen omdat de bezoeker aan mijn blog toch meer uit Nederland komen en omdat het posten in mijn eigen taal wat sneller en makkelijker gaat. Daarbij werkt google translate steeds mooier dus dat moet geen probleem zijn.

Tot de volgende keer..

Using Lync 2010 client in Office Communications Server 2007 R2 environment

Ramon van Bruggen — Tue, 26 Apr 2011 07:31:33 +0000

While the new Lync Client brings a lot of new functionalities and a complete new look, it isn’t compatible with a OCS 2007 R2 environment. Another downside is that it can’t be installed together with Communicator 2007 on a single machine. When working on both 2007 R2 and Lync 2010 projects, this means the usage of VM’s or uninstall and re-installing a lot, two options which I don’t like personally.

Out-of-the-box the client will give you an error message when you try to sign in into an OCS 2007 R2 pool, stating that the version is not correct. This tells me there IS some kind of communication, however, it’s being detected and blocked.

After some research I found a way to be able to run the Lync 2010 client on a OCS 2007 R2 environment – simply by bypassing a version check. To bypass this check, you have to create a new registry entry:
Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Communicator
Name: DisableServerCheck
Type: DWORD
Value: 1 (00000001)

When this entry has been created, the version check will be skipped, and the Lync Client WILL logon to the OCS 2007 R2 environment. Actually, most of the functionalities just work fine! IM, Presence, calling and video work all as espected.

Of course there are some functionalities which don’t work correctly. One of these functionalities is the “Live Meeting” functionality; this is now built-in into the Lync Client, while in the previous version it was a separate client. Installing Lync will uninstall the LiveMeeting plug-ins in outlook as well, disabling you to schedule an old-fashion meeting. But hey, at least now we can connect to both environments with this new client!

Ramon van Bruggen — Thu, 14 Apr 2011 11:34:00 +0000

Microsoft has announced the first beta release of Silverlight 5 today. According to TNW, the beta download is available on the official Silverlight site.

The Silverlight 5 beta adds a number of new features and capabilities, which include, graphic improvements and performance improvements such as network latency reduction and 64-bit support.

The official site also shows off some of the main new features aimed at helping developers reach new heights in delivering rich Internet based applications. They include:

Hardware Decode and presentation of H.264 improve performance for lower-power devices to render high-definition video using GPU support.
TrickPlay allows video to be played at different speeds and supports fast-forward and rewind. At up to twice the speed, audio pitch correction allows users to watch videos while preserving a normal audio pitch.
Improved power awareness prevents the screen saver from being shown while watching video and allows the computer to sleep when video is not active.
Remote-control support allows users to control media playback.
Digital rights management advancements allow seamless switching between DRM media sources.

While the official beta site mentions additional features such as:

XAML Debugging with breakpoints for binding debugging
Implicit data templates for easy UI reuse
Double (and multi) click support
GPU-accelerated XNA-compatible 3D and immediate-mode 2D API
Low-latency sound effects and WAV support

Foscam Clone Recovery (Teil 2)

Ramon van Bruggen — Fri, 14 Jan 2011 14:33:34 +0000

To follow up on my previous post, the news is that I have successfully dumped all firmware parts of my camera. The bad news is that it didn’t work on my camera.

The problem is this:

audio_dev.state not AU_STATE_RECORDING
wb_audio_start_record
inet_sr.c INET_rinput 321
action===1
options==33
inet_sr.c INET_setroute 75
*args===255.255.255.255
*args===netmask
*args===eth0
[29]
write i2c error
write i2c error
write i2c error
write i2c error
write i2c error
write i2c error
write i2c error
write i2c error
write i2c error
write i2c error
myreboot

Every time the camera is almost at the end of the boot process it try’s to read “something” and after that fails it reboots itself!! The problem is that this is exact the same problem I have with all firmware’s I tried.

Ich beginne zu glauben, dass in den neuesten Revisionen der Kamera gibt es eine Art von Sicherheits-Chip in der Kamera zu bauen und wenn die Firmware nicht dieser Chip oder irgendeine Art von CRC Code erkennt es neu gestartet!

Eine weitere seltsame Sache, die ich gesehen habe ist, dass wenn Sie blinkt die "romfs.img" auf die Kamera es Änderungen Teil. Ich habe einen Dump des Teils "romfs.img" und es ist anders dann das Bild ich blitzte es, but is exactly the same as what is on the camera.

Ich werde mein Werkzeug an diesem Beitrag für andere zu experimentieren. Sie haben nicht vergessen, dass das "Gesamt, Ihre eigene Software!!” Ich bin nicht verantwortlich für jegliche Schäden, die das Tool auf der Kamera führen kann! OK gut damit aus dem Weg, a little bit of explanation of how the tool works.

Step 1

Press the browse button to select a folder to dump the firmware to.

Step 2

Wählen Sie den Port wo Sie RS232 Gerät ist, und wählen Sie"Open Port”

Step 3

Nach dem Klicken auf die Schaltfläche "Open Port" müssen Sie Ihre Kamera anschließen, Wenn alles gut geht, sehen Sie die Meldung"Kamera”t im "Bootloader" Modus”

Step 4

Klicken Sie auf die Schaltfläche"Dump Firmware

Step 5

Wählen Sie die Firmware-Images, die Sie möchten dump und klicken Sie auf die Schaltfläche "Dump"

Step 6

The tool will start dumping the selected images and if all goes well you will end up with a working copy of your firmware.

Ich muss sagen, Da das Tool RS232 seriellen Kommunikation verwendet, um die Firmware zu dumpen ist es nicht sehr stabil, Es ist sehr wahrscheinlich, dass Sie Erfolg haben wird nicht sofort die Firmware zu dumpen, Es dauert wahrscheinlich ein paar Mal um es richtig zu machen, but I wanted to share the tool for those who might find it useful.

Foscam Clone Recovery Tool

Ramon van Bruggen — Sat, 08 Jan 2011 00:37:55 +0000

Ich kaufte vor kurzem ein paar dieser Kamera:
http://www.Chinavasion.com/product_info.php/pName/IP-Surveillance-Camera-with-Angle-Control-and-Motion-Detection/

Dort nicht sehr gut, aber für so viel Geld was können wir erwarten! After installing the cams and playing a bit with them the natural urge to flash the latest firmware to a device came over me.

Ich schaute auf die Seite des China Vasion, aber nicht alles von einer neuen Firmware finden konnte. Ein wenig enttäuscht, ich Suche bei Google und fand heraus, dass diese Kamera ein Klon von Foscam ist. Ich sofort über die Website der original Foscam Kamera stürzte und herunterladen das neueste Firmware. nächste, was, das ich wusste, dass ich saß hinter meinem Schreibtisch mit einem gemauerten Gerät in meine Hand...

Ich suchte das ganze Internet in der Hoffnung, einen Weg finden, mein gemauerte Gerät wiederherstellen. Ich habe viele Geräte vor zugemauert., and usually there is a backdoor in.

Ich fand ein paar sehr interessante Seiten:
http://www.gadgetvictims.com/2009/12/Bring-Your-fi8908w-Paperweight-Back-to.html
http://www.computersolutions.cn/Blog/2010/05/IP-CAM-Hacking-–-PT6/
http://irishjesus.wordpress.com/2010/03/30/hacking-the-foscam-fi8908w/

Gadget Victems beschreibt einen Weg, um in den Bootloader, der das Gerät über eine serielle Verbindung. I opened up the cam and soldered the wires on the serial connection pads.

Ich versuchte jede Firmware, die ich gefunden, aber keiner Tat die Tücke. I always ended up with my cam in an endless loop of reboots.

Anschließend überprüft die Bootloader Befehle und sah eine Option namens: Anzeigenspeicher (D). Wenn Sie z. B. eingeben: D -b 0x7F0E0000 Es zeigt die erste 256 bytes from that address like below.

Ich wollte wirklich meine Kameras zurück, damit ich dieses Tool schnell und schmutzig heute gehackt, Es sichert alle Speicher von einem bestimmten Speicherbereich. Ich habe einige Tests und hat einen Vergleich mit der Ausgabe von mein Werkzeug und die original-Firmware und es war ein Spiel!!

Ich habe hier eine gute Kamera im Moment so ich kann nicht überprüfen, ob dies mein Problem lösen wird, but at least I can dump the firmware of any Foscam Clone Camera.

Sobald ich einige mehr getestet und ich einige zusätzlichen Optionen für das Tool habe machen ich zur Verfügung für alle es will, es zu benutzen!

Prost,

One Click Firmware Updater for Netduino’s

Ramon van Bruggen — Tue, 26 Oct 2010 12:55:46 +0000

I have created a one click firmware updater for the Netduino! The tool was initially build by forum user Randoom for the FEZ Devices. I took that code as my base and created the Netduino One Click installer. It detects a Netduino automatically and reads the currently installed firmware version, after that the tool will check on a remote site if there is a newer version of the firmware available (currently it is my blog). If it detects the version on the Netduino is older you can click the update firmware button to update your Netduino!

A few things to keep in mind:
1. It is alpha software and not for people who do not know how to recover if something goes wrong.
2. You need an internet connection if you would like to use the auto update feature.
3. It currently only supports the Netduino, so not the Plus or Mini, those will be supported in later versions.

If you would like to test please remember you have to have version 4.1.0.3 on your Netduino, so you can test the automatic update feature. I have 4.1.0.4 on the update server.

I hope you like the tool! Please let me know what you think!

You can download the Updater here: One Click Updater for Netduino

New day, new parts, soldering irons ready!

Ramon van Bruggen — Fri, 15 Oct 2010 09:14:55 +0000

The mailman delivered a nice box today. In the box I found two nice little Panda’s! And a few USBizi144 chips!

After I got the courage to try to solder the 144 pin beast onto the board, I was ready to go! I never soldered anything big like this, so fingers crossed!


PCB Layout file, ready to go	My two helpers, guarding my soldering iron

All went pretty well, it is not absolutely lined out correctly, but considering its my first time

A few days later the rest of the parts for my DIY FEZ Domino arrived, after a half an hour of soldering this was the end result!

The most exiting part was plugging it into my PC, all I could do was pray I wouldn’t see any white or black smoke

The first problem I faced was that the 5V voltage regulator seemd to get power from USB what is not supposed to happen, it got VERY hot VERY fast, so I decided to desolder that part. After I removed it my PC started to beep the sound of a USB device that got plugged in. It only showed a serial port (COM4) that was not what I expected, I thought I would see a USB device. I checked the USBizi144 documentation and saw that the chips come without firmware, so only a bootloader is installed.

After firing up TeraTerm and selecting the COM port and after downloading the latest firmware I got my board up and running! I started Visual studio, created the “Hello World” on hardware boards (blinking led) and ran the code, everything worked!

FEZ Domino DIY Projekt

Ramon van Bruggen — Fri, 01 Oct 2010 14:26:37 +0000

I decided to take the ultimate challenge, at least for me, and that is that I am going to build a FEZ Domino from scratch, well not exactly from scratch, but anyway. I downloaded the schematics and PCB layout from the TinyCLR.com website. Next I went to my favorite PCB house Seeed Studio and ordered 10 PCB’s. I placed my order at the 14^th of September, the boards where ready and shipped the 19th. Today the 30th September I received my boards!

Now the waiting is for my USBizi LQFP144 chips! I hope they will ship together with my FEZ Panda boards on October 1^st

The biggest challenge with building these boards will be soldering the really fine pitch 144 pins chips.

I will post follow ups as soon as I have the parts!
