			<content:encoded><![CDATA[<p>This week, Samsung decided to give me a Galaxy Note for a week to evaluate it in real use. Thanks for that, it&#8217;s a nice way for me to determine the current status of android and the quality of Samsung devices. </p>
<p>After a few days, I&#8217;ve switched back to my iPhone. But the whole story first.</p>
<p>The Galaxy Note is a huge smartphone. It&#8217;s really huge – you basically have to have both hands available if you want to do anything, as reaching over the screen is impossible ( given my thumb length, at least ). That&#8217;s the first obvious thing I noticed. Huge screen. Huge device. </p>
<p>After the device boots, which is quite fast, a home screen cluttered with all kinds of widgets presents itself. It&#8217;s completely full. 6 Pages full of stuff I never asked for. So the first task for me was to remove all of that stuff to get a clean start. </p>
<p>The next thing that bothered me was that I had to reboot the device 8 (!) times for all updates to install. And even after all updates were installed, the Android version running wasn&#8217;t Ice Cream Sandwich ( the current one ), but still 2.3.6, which is over 6 months old. Don&#8217;t get me wrong, 6 months isn&#8217;t a big deal, but I was actually looking forward to testing a device with a current Android version. </p>
<p>Actually using the device at home is fun. It&#8217;s snappy, the screen is really bright and nice to read stuff on. The device itself is really light, which is astonishing given the size. The drawback is that the material choice reflects that weight: everything feels a bit &#8220;cheap&#8221;, i.e. the back cover is a simple piece of plastic, about a mm thick, thats completely bendable, without any structure whatsoever. This may be a good design choice, but it simply doesn&#8217;t go well with the pricing. Even old Nokia phones had a thicker back. </p>
<p>It&#8217;s a phone, so one wants to make phone calls. It works, of course. But once I installed my bunch of standard apps ( RunKeeper, Skype, Foursquare, Facebook, Twitter, Whatsapp and few others ) the default behavior vanished and every time I was about to call someone, the system asked me whether it should use Skype or the Phone application. So annoying, impairs productivity without any gain. </p>
<p>I still don&#8217;t get my head around the decision someone made to include a stylus in the Note. I used it to draw some stuff, but actually, I considered it a toy. And, for a dualcore 1.4Ghz CPU, it&#8217;s disappointing that the input lags when drawing using the stylus. And it does. </p>
<p>The question that remains for me: is there a real benefit from carrying around a giant screen at all times? For the occasional read, it&#8217;s really handy. What bothers me is the lack of a UI concept that effectively uses the bigger screen to generate a better user experience. Most apps are simply pulled up without any adaption to the screen size. So you basically have the same app, different size. There are some built-in ones that try tablet patterns, but the general impression is that no one really thought about it hard enough. </p>
<p>When it comes to productivity, I was reminded of the unfortunate fact that iCloud isn&#8217;t all-so compatible with the Android world as I wished it was. I&#8217;m running a full Apple-Setup: MacBook, iMac, iPad and normally iPhone. I&#8217;m pretty much used to everything working very smooth. I refrained from buying an app that let&#8217;s me sync my iCloud calendar and just stuck with creating events somewhere else. Given the market share of Apple devices, the decision to not support iCloud at least rudimentary doesn&#8217;t make much sense. Well, maybe it&#8217;s Apple blocking the development, I don&#8217;t know.</p>
<p>So, why have I switched back? I need a reliable device that integrates well into my environment and is easy to use at all times. The Note is a good device, but given my Apple-centric environment, it was just too much pain syncing and setting up stuff. Sorry Samsung.</p>

			<content:encoded><![CDATA[<p>Last thursday, some local nerds joined in for the first ( and certainly not last ) HackerNews meetup in Stuttgart at CoWorking 0711. </p>
<p>With about 15 people present, we had the chance to listen to some really great stuff. <a href="http://dividuum.de/">Florian Welsch</a> ( dividuum ) talked about a project of his called <a href="http://geolua.com/">Geolua</a>, a web-based geo-based game creator that allows writing games in lua. It was a fun talk and certainly very inspiring ( especially the debugging-functionality <img src='http://momo.brauchtman.net/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' />  ). </p>
<p>Jan gave us a chance to learn a bit about <a href="http://unhosted.org/#introduction">unhosted.org</a>, a project that aims at separating data from logic in web applications with the goal to let users regain control of their data. </p>
<p><a href="http://www.marc-seeger.de/">Marc</a>, my co-organisator, explained how he uses Cucumber, a Ruby Testing-Framework to write test in seemingly natural language. </p>
<p>Seems like it worked out the way it was supposed to. Thanks everyone for being there, listening, discussing and talking. See you next time! </p>

			<content:encoded><![CDATA[<p>I think it&#8217;s a common experience for software developers to have some abandoned, failed, outdated or otherwise discontinued projects somewhere on your disk. I also think that it&#8217;s okay to start projects and to not finish them – sometimes the purpose of a project is to learn something new, waste time or pretend to be busy.</p>
<p>Given my assessment of the situation is correct, there must be a huge amount of code existing in the depths of our filesystems that a) doesn&#8217;t attract us anymore b) may be interesting for others to see and maybe work on.</p>
<p>So what&#8217;s the donate a project day? A simple idea: We figure out a certain date ( say, March 31 ). At that date, every participant publishes one of his or her abandoned projects at github or bitbucket. The second condition is that each participant must write something about the project, i.e. the motivation for starting it and some of the reasons that made him abandon it.</p>
<p>For the day to work great, we should have a page where all donated projects are collected and presented, as well as the common agreement that an open source license should be used for the published code, so others can continue where you stopped.</p>
<p>What&#8217;s important isn&#8217;t that your code is super-polished, perfectly documented or completely covered by tests, but rather that you just share it with others.</p>
<p>This is just a rough idea. What do you think?</p>

I feel this is a more honest way of trying to make some money of this blog than by annoying you with advertising.</p>
<p>I hope it works.</p>

			<content:encoded><![CDATA[<p><a href="http://www.macrumors.com/">MacRumors has reported</a> that someone discovered a new iOS weakness which developers can use to upload the entire photo library. This is true, and the only thing a user has to do is to accept that an app can access location data for videos and photos. Afterwards, the developer has complete access to your library, and can do withit whatever he wants.</p>
<p>As a matter of fact, this is not a security problem. It could be a privacy problem, but I wouldn&#8217;t be too fast in suggesting that. You&#8217;ll most likely notice when someone is uploading your library to some server ( I just tried. ). What&#8217;s stunning here is that people are running around, claiming to be security experts or some other blubberdiblu, while the actual mechanics to retrieve the pictures is a public API built into iOS that should be known by every so-called App Developer: the <a href="https://developer.apple.com/library/ios/#documentation/AssetsLibrary/Reference/ALAssetsLibrary_Class/Reference/Reference.html">ALAssetsLibrary</a> and friends. This API is exactly useful to do one thing: retrieve images from the internal library. Nothing new, it has been around since iOS4.</p>
<p>By the way, every Android App has <em>full reading permissions to all files on the SD-Card</em>, which is where usually photos are stored. ( According to <a href="http://www.vogella.de/articles/AndroidFileSystem/article.html">Lars Vogel&#8217;s Android tutorial on writing and reading files</a> ).</p>
<p>Oh, and before I forget to mention that: Same is true for WP7, there is comparable API for accessing picture data. ( see <a href="http://stackoverflow.com/questions/4609051/access-photos-stored-on-wp7-device">http://stackoverflow.com/questions/4609051/access-photos-stored-on-wp7-device</a> ) .</p>

<p>There is no platform war, as well as there is no winner. It&#8217;s called diversity, and it&#8217;s a good thing. Stop using inappropriate terminology. War is when people suffer and die. Not when kernel architectures or UI-concepts compete.</p>
<p>Someone using something you don&#8217;t like? Don&#8217;t bother. Why bother? They almost always had good reason for their decision. If they need your advice, they are going to ask you anyway. If not, leave them alone.</p>
<p>Instead of wasting your time fighting for technologies that will be outdated in at least two years, create something that lasts a bit longer. Create something.</p>

			<content:encoded><![CDATA[<p>I just noticed, after reading the excellent <a href="http://klinger.io/post/17313437389/my-addressbook-keep-it-telephone-numbers-are-a?bf8f3878">blog post by Andreas Klinger</a> about phone numbers, that I never really talked about what I did in my thesis on my blog.</p>
<p>My thesis had the title &#8220;Distributed Management of personal contact data&#8221; and dealt with analyzing the problem that current data management facilities ( read: address books ) are suffering from and proposed a protocol for creating a distributed contact management facility.</p>
<p>My motivation was the problem described by Andreas, in one form or another. While I didn&#8217;t discuss phone numbers in detail, I think they are a great example for why any of todays used management systems are inpractical.</p>
<p>The system I suggested and subsequently built in a team with<a href="http://www.roothausen.de/"> Sven Pfleidere</a>r was distributed, simple, HTTP based and privacy-aware – that is encrypted, so that it doesn&#8217;t need HTTPS. The focus was also to design it in a way that would make it easy to implement and suited to run on cheap non-dedicated servers.</p>
<p>Unfortunately, I didn&#8217;t have the time after completing my thesis to create a working platform demoing the whole idea. After the appearance of diaspora, I was convinced that the problem would solve itself, but these guys never even bothered to write a nice protocol spec altogether.</p>
<p>If you care about the whole piece of work,<a href="http://momo.brauchtman.net/wp-content/uploads/2012/02/thesis1.pdf"> you can grab it here</a>. There may be some typos/mistakes in it, please don&#8217;t let me know. What I&#8217;d like to know is what you think about it.</p>
<p><strong>Update: </strong>Posted wrong thesis. ( &#8230; )</p>

			<content:encoded><![CDATA[<p>Da ich, wie die meisten aufmerksamen Leser dieses Blogs vielleicht schon bemerkt haben, Technik- bzw. IT-affin bin, und sich diese traurige Wahrheit auch schon in meinem Bekanntenkreis herumgesprochen hat, möchte ich an dieser Stelle alle zukünftigen Anfragen zum Thema Notebook-Kaufberatung in einem Blogpost final beantworten. Aufgrund des Entwicklungsstands moderner Geräte ist es denke ich sicher anzunehmen, dass dieser Post für die nächsten 2-3 Jahre gültig bleibt.</p>
<p>Die grundlegenden Anforderungen der meisten Leute, die mit der Frage &#8216;Welches Notebook soll ich mir kaufen&#8217; zu mir kommen, sind sehr vergleichbar. Es werden Office-Fähigkeiten gesucht, weiterhin sollte ein Browser vernünftig laufen und kleiner Multimedia-Aktionen sind auch vorgesehen – Zum Beispiel ein Test von Photoshop für nichtkommerzielle Zwecke oder das Bearbeiten eines kleinen Videos.</p>
<p>Hier kommt die gute Nachricht: Mir fällt beim besten Willen kein Gerät ein, das heute, 2012, produziert und verkauft wird, dass diese Fähigkeiten nicht besitzt. Dieses Phänomen kann wirklich gut mit dem <a href="http://de.wikipedia.org/wiki/Mooresches_Gesetz">Mooreschen Gesetz</a> belegt werden, dass 1965 von Gordon Moore formuliert wurde, und besagt, dass sich &#8220;die Komplexität integrierter Schaltkreise mit minimalen Komponentenkosten regelmäßig verdoppelt&#8221;, im Original alle 24 Monate, nach Intel all 18 Monate. Dieses Gesetz hat bis heute Gültigkeit in einer Vielzahl von Bereichen, unter anderem der Pixelzahl der Sensoren einer Digitalkamera, Festplattengrößen und natürlich auch der Komplexität und somit Geschwindigkeit von Computerprozessoren.</p>
<p>Was das bedeutet, ist dass ein Rechner aus dem Jahr 2012 ungefähr doppelt so schnell ist als ein preislich Vergleichbarer Rechner aus dem Jahr 2010, wobei dieser ebenfalls wieder doppelt so schnell war wie ein Rechner aus dem Jahr 2008 usw..</p>
<p>Die Implikationen für den normalen Benutzer sind, dass man heutzutage relativ sicher sein kann, dass die Rechner die man bekommt wirklich schnell genug für alles sind. Die Rechenleistung kann also nur marginal entscheidend für die Kaufentscheidung sein.</p>
<p>Gehen wir also weiter zu einem spannenden Thema, nämlich dass der internen Komponente wie z.B. Arbeitsspeicher und Festplatte. Arbeitsspeicher ist sozusagen der Schreibtisch des Prozessors, hier werden wichtige Daten direkt und schnell zugreifbar Abgelegt. Während vor 15 Jahren 16MB noch Luxus waren, sind heute 2 oder 4GB in Consumer-Rechnern Standard, was wiederum völlig ausreicht, wenn man sich in der Office,Internet,Photoshop-Ecke befindet.</p>
<p>Die Festplatte hingegen ist die einzige Komponente von der man sagen kann dass sich die Entwicklung im Umbruch befindet. Technisch sind heute 3 Terabyte-Platten keine Sensation mehr und gängig. Das Problem mit Festplatten ist jedoch deren mechanische Bauart und somit begrenzte Geschwindigkeit. Seit mehreren Jahren entwickelt sich zunehmende der Trend zu sogenannten<a href="http://de.wikipedia.org/wiki/Solid-State-Drive"> Solid State Drives ( SSD )</a>, die auf einer ähnlichen Technologie wie Arbeitsspeicher oder USB-Sticks basieren. Das macht sie zum einen Energieeffizienter, zum anderen aber auch um ein Vielfaches schneller als konventionelle Festplatten. Da die Produktion und Fertigung dieser SSDs jedoch aufwändiger ist als die von herkömmlichen Festplatten, schlägt sich das im Moment noch im Preis nieder – konventionelle Festplatten kosten ca. 8-15 Cent pro GB, während es bei SSDs bei 90 Cent pro GB anfängt. Wer Wert auf absolute Geschwindigkeit legt, investiert gut in eine SSD, für viele normale Benutzer macht es jedoch wahrscheinlich einen vernachlässigbaren Unterschied. Wichtig ist zusätzlich noch dass SSDs keine mechanischen Komponenten haben, also sehr stoßunempfindlich sind und keine Geräusche machen.</p>
<p>Was ist bei einem Notebook noch wichtig? Das hängt immer vom persönlichen Nutzungsschema ab, ich werde hier noch auf die Punkte Verarbeitungsqualität, Bildschirmgröße/Auflösung und Akkulaufzeit eingehen.</p>
<p>Der Bildschirm ist der wohl sichtbarste und wichtigste Teil eines Notebooks. Gerade bei den Displays findet man die größten Unterschiede zwischen günstigen und hochpreisigen Geräten. Teilweise befinden sich in hochpreisigen 11&#8243;-Geräten Bildschirme mit höheren Auflösungen ( also einer höheren Anzahl an Pixeln ) als in billigen 15&#8243; Geräten. Dieser Unterschied macht sich beim Arbeiten gewaltig in ganz simpel mehr oder weniger Fläche auf dem Desktop bemerkbar und entscheidet im Zweifel darüber, ob man ständig Scrollen muss oder das meiste schon sieht. Hier ist also ganz offensichtlich genaues hinschauen beim Kauf gefragt – die einzige Lösung hier später einen Fehlkauf zu verbessern ist ein externer Monitor der an das Notebook angeschlossen wird. Grundsätzlich sollte alles über <a href="http://en.wikipedia.org/wiki/Display_resolution">1440&#215;900</a> ( Richtwerte ) bei 13&#8243;-15&#8243; als ausreichend angeshene werden. Werte darunter sind natürlich, je nach Geldbeutel, erhältlich, jedoch sinkt in meinen Augen mit einer zu kleinen Auflösung die Produktivität überdurchschnittlich.</p>
<p>Wo wir schon beim nächsten Punkt sind – Produktivität. Die wichtigsten sichtbaren Komponenten eines Notebooks sind die Tastatur und das Trackpad. Während die Tastatur heute meistens im Chiplet-Design gebaut wird ( d.h. mit kleinen Abständen zwischen den Tasten ), gibt es bei den Trackpads gravierende Unterschiede. Für beide Punkte gilt allerdings dass man hier am besten in einem Laden &#8220;Probetippt&#8221;, da sich gerade bei Tastaturen die Geister scheiden. Wichtige Metriken für das Trackpad sind vor allem die Größe und ob und wie Scrolling unterstützt wird, d.h. ob ein virtuelles &#8220;Mausrad&#8221; eingebaut ist. Auch hier finden sich zwischen den Preisniveaus große Unterschiede, und gerade billige Geräte fallen durch eine &#8220;Billige&#8221; Verarbeitung negativ auf. Wer nicht ständig anbauen will ( Externe Maus, Tastatur ) ist gut beraten gleich richtig zu kaufen.</p>
<p>Generell ist die Frage, wieviel Wert man auf die Verarbeitung des Notebooks legt – es liegt auf der Hand dass sich dier Hersteller gerade in diesem Punkt deutlich diversifizieren. Wer damit leben kann dass sein Notebook komplett aus Plastik kommt und nach 4 Monaten zu klappern und zu wackeln anfängt, der ist wohl mit 300 Euro im Rennen. Wer etwas mehr Wert auf langlebigkeit legt muss wahrscheinlich tiefer in die Tasche greifen.</p>
<p>Wer sich oft unterwegs an die Arbeit macht, interessiert sich spätestens seit Starbucks die Steckdosen abgebaut hat für die Akkulaufzeit seines mobilen Begleiters. Spätestens wenn der mobile Alleskönner nach 50 Minuten schwarz wird, weil die Batterie leer ist, wird sich noch darüber freuen, immer das in der Regel schwere Netzteil noch mitzunehmen. Gute Akkulaufzeit wird zum einen aus einer guten Abstimmung der Komponenten auf das hoffentlich aktuelle Betriebssystem, vernünftige Nutzung und die größe der eingebauten Batterie beeinflußt. Die Klassenbesten erreichen heute übrigens Laufzeiten von 5-7 Stunden, während viele Notebooks im günstigen Segment ( 300-500 Euro ) gerade mal 1-2 Stunden oder weniger schaffen. Wie immer: Sich vorher überlegen was man braucht. Nur daheim: billig kaufen, nur draußen: teuer kaufen.</p>
<p>Zuletzt möchte ich noch auf den bekannten Ausstoß &#8220;900 Euro für ein Notebook sind zuviel&#8221; eingehen. Ich will nicht in Frage stellen dass 900 Euro viel Geld sind, gerade für Studenten oder junge Leute mit wenig Einkommen. Man muss sich aber immer auch überlegen, wie lange man ein Notebook sinnvoll nutzen möchte &#8211; gerade MacBooks lassen sich gut 3 Jahre nutzen und danach immer noch für die Hälfte des Kaufpreises verkaufen.</p>
<p>Aber genug geredet, hier eine unvollständige Liste von Geräten in jeder Preiskategorie.</p>
