    <title>Tigions Blog: Pentax K-01</title>
    <id>http://blog.tigion.de/2012/02/02/pentax-k-01/</id>

<p>Pentax ist jetzt auch auf den Zug der spiegellosen APS-Kameras aufgesprungen und präsentierte heute die neue Systemkamera <a href="http://www.pentax.de/de/systemkameras/k-01.html">Pentax K-01</a>. Als Farbvariation gibt es Schwarz, Silber und Gelb.</p>
<p>Die <a href="http://www.pentax.de/de/systemkameras/technische-details/k-01.html">technischen Daten</a> klingen recht beachtlich und der Abstand zur Pentax K-5 dürfte, wie vom Preis auch, nicht all zu gross sein. Ich hoffe nur das die Qualität besser geworden ist, denn bei der K-5 gab es ja leider einige Mängel.</p>
<p>Ein großer Pluspunkt ist die Kompatibilität zum Pentax KA-Bajonett, was die Verwendung aller aktuellen DSLR Objektive von Pentax erlaubt. So gibt es zum Start schon eine sehr große Objektivauswahl. Nachteilig könnte die daraus resultierende Größe sein. <span id="more-1270"></span></p>
<p>Das Design kommt vom Industriedesigner <em><a href="http://www.marc-newson.com/">Marc Newson</a></em>, welcher auch im folgenden Interview auf das Design der Pentax K-01 eingeht:</p>
<p><iframe allowfullscreen src="http://www.youtube.com/embed/mrXKDrg-xy8?rel=0" frameborder="0" height="279" width="450"></iframe></p>
<p>Ich selbst finde das Design recht gewöhnungsbedürftig und schwer von den Fotos her einschätzbar. Sie wirkt erstmal recht klobig. Andererseits ist es ein bewusst klareres und flächigeres Aussehen, wo man jedoch den Retrocharme, wie bei <a href="http://finepix.de/cms/home/produkte/digitalkameras/premium/fujifilm-x10/uebersicht/">Fujifilm X 10</a> vermissen könnte. Ist halt die Frage was man an Größe und Aussehen haben will.</p>
<p>Ich werde sie sicher mal im Laden direkt in die Hand nehmen und mir eine genauere Meinung bilden. Aber Bedarf für eine Systemkamera habe ich zur Zeit nicht, wofür hab ich denn DSLRs im Schrank stehen. Ist aber gut zu wissen, dass die Objektive passen würden. <img class="wp-smiley" src="http://blog.tigion.de/wp-includes/images/smilies/macinacs_smile.gif" alt=":)" /> </p>

<p>2012 werden meine gute alte Kamera Pentax K200D und ich einen neuen Brennweitenbereich austesten. Statt 50mm sind die noch ungewohnten <strong>35mm</strong> anvisiert. Als zusätzliche Herausforderung stehen mir das manuelle Scharfstellen und die schwarzweiße Farbausrichtung zu Seite.</p>
<p>Ausgerüstet mit einem M42 Adapter und einer 35mm Flektogon f/2.4 Festbrennweite liegt es jetzt eigentlich nur noch an mir wieder mehr raus zu gehen und im richtigen Moment den Auslöser zu drücken.</p>
<p>Der Blick durch die Tür raus auf die Strasse ist quasi ein symbolischer Anfang. <img class="wp-smiley" src="http://blog.tigion.de/wp-includes/images/smilies/macinacs_smile.gif" alt=":)" /> </p>

    <title>Inductive Bias: Clojure in Berlin</title>
    <id>http://blog.isabel-drost.de/index.php/archives/366/clojure-in-berlin</id>
    <link href="http://blog.isabel-drost.de/index.php/archives/366/clojure-in-berlin" rel="alternate" type="text/html"/>
    <link href="http://blog.isabel-drost.de" rel="via" type="text/html"/>
    <content type="xhtml">
      <div xmlns="http://www.w3.org/1999/xhtml"><p>Though I had the chance to tinker with some Clojure code only briefly it&#8217;s programming model and the resulting compact programs do fascinate me. As the resulting code runs on a JVM and does integrate well with existing Java libraries migration is comparably cheap and easy.</p>
<p>Today I finally managed to attend the local <a href="http://www.meetup.com/Clojure-Berlin/">Berlin Clojure meetup</a>, co-organised by Stefan Hübner and Fronx. Timing couldn&#8217;t have been much better: In this evenings event Philip Potter from Thoughtworks introduced <a href="http://overtone.github.com/">Overtone</a> - a library for making music with Clojure.</p>
<p>After <a href="https://github.com/overtone/overtone/wiki/Installing-overtone">installing and configuring</a> jack for sound output, supercollider, and overtone outputting your first tone is as simple as registering the overtone library and typing<br />
<code><br />
(definst foo [] (saw 220))<br />
(foo)<br />
</code><br />
To stop it type (stop).</p>
<p>Other types of waves of course are supported as well, so is playing different waves simultaneously and modifying them at runtime. Also expressing sounds as notes (c, d, e, f, g) that may have a certain length is possible of course – which makes it so much easier to design music than having to thing in frequencies.</p>
<p>A sample of what can easily be done with Overtone:</p>
<p><iframe scrolling="no" src="http://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F35276769&#038;show_artwork=true" frameborder="no" height="166" width="100%"></iframe><br />
<small>Original sound way better - this sample was taken with a mobile phone, compressed, re-coded and then put online. Checkout Overtone project for the real thing - and don&#8217;t even try to listen to the sample with low-end laptop speakers <img class="wp-smiley" src="http://blog.isabel-drost.de/wp-includes/images/smilies/icon_wink.gif" alt=";)" /> </small></p>
<p>Overall a well organised meetup (Thanks to Soundcloud for hosting it, to the organisers for putting it together and to the speaker for a really well done introduction to Overtone) and an interesting way to get started with Clojure with very fast (audio) feedback.</p>

    <title>Inductive Bias: February 2012 Apache Hadoop Get Together Berlin</title>

    <content type="xhtml">
      <div xmlns="http://www.w3.org/1999/xhtml"><p>The upcoming Apache Hadoop Get-Together is scheduled for 22. February, 6 p.m. - taking place at Axel Springer, Axel-Springer-Str. 65, 10888 Berlin. Thanks to Springer for sponsoring the location!</p>
<p>Note: It is important to indicate attendance. <b>Due to security restrictions at the venue only registered visitors will be permitted</b>. Get your ticket here: <a href="https://www.xing.com/events/hadoop-22-02-859807">https://www.xing.com/events/hadoop-22-02-859807</a></p>
<p>Talks scheduled thus far:</p>
<p>Markus Andrezak : &#8220;Queue Management in Product Development with Kanban - enabling flow and fast feedback along the value chain&#8221; - It&#8217;s a truism today that fast feedback from your market is a key advantage. This talk is about how you can deliver smallest product increments or MVPs (minimal viable products) quickly to your market to get fastest possible feedback on cause and effect of your product changes. To achieve that, it helps to provide a continuous deployment infrastructure as well as all you need for A/B testing and other feedback instruments. To make the most of these achievements, Kanban helps to limit work in progress, thus manage queues and speed up lead times (time from order to delivery or concept to cash). This helps us speed through the OODA Loop, i.e. Eric Ries&#8217; (The Lean Startup) Model -> Build -> Code -> Measure -> Data -> Validate -> Model. The more we can go through the loop, the more we have a chance to fine tune and validate our model of the business and finally make the right decisions.</p>
<p>Markus is one of Germany’s leading Kanban practitioners - writing and presenting talks about it in numerous publications and conferences. He will provide a brief view into how he is achieving fast feedback in diverse contexts.<br />
Currently he is Head of mobile commerce at mobile.de.</p>
<p>Martin Scholl : &#8220;On Firehoses and Storms: Event Thinking, Event Processing&#8221; - The SQL doctrine is still in full effect and still fundamentally affects the way software is designed, the state it is stored in as well as the system architecture. With the NoSQL movement people have started to realize that the manner in which data is stored affects the full stack &#8212; and that reduction of impedance mismatch is a good thing(TM). &#8220;Thinking in events&#8221; follows this tradition of questioning what is state-of-the-art. Modeling a system not in mutable entities (as with data stores) but as a stream of immutable events that incrementally modify state, yields results that will exceed your expectations. This talk will be about event thinking, event software modeling and how Twitter&#8217;s Storm can help you process events at large.</p>
<p>Martin Scholl is interested in data management systems. He is also a Founder of infinipool GmbH.</p>
<p>Fabian Hüske : &#8220;Large-Scale Data Analysis Beyond Map/Reduce&#8221; - Stratosphere is a joint project by TU Berlin, HU Berlin, and HPI Potsdam and researches &#8220;Information Management on the Cloud&#8221;. In the course of the project, a massively parallel data processing system is built. The current version of the system consists of the parallel PACT programming model, a database inspired optimizer, and the parallel dataflow processing engine, Nephele. Stratosphere has been released as open source. This talk will focus on the PACT programming model, which is a generalization of Map/Reduce, and show how PACT eases the specification of complex data analysis tasks. At the end of the talk, an overview of Stratosphere&#8217;s upcoming release will be given.</p>
<p>Fabian has been a research associate at the Database Systems and Information Management (DIMA) group at the Technische Universität Berlin since June 2008. He is working in the Stratosphere research project, focusing on parallel programming models, parallel data processing, and query optimization. Fabian started his studies at the University of Cooperative Education, Stuttgart, in cooperation with IBM Germany in 2003. During that course, he visited the IBM Almaden Research Center in San Jose, USA, twice and finished in 2006. Fabian undertook his studies at Universität Ulm and earned a master&#8217;s degree in 2008. His research interests include distributed information management, query processing, and query optimization.</p>
<p>A big Thank You goes to Axel Springer for providing the venue at no cost for our event and for paying for videos to be taped of the presentations. A huge thanks also to <a href="http://www.linkedin.com/profile/view?id=9861942&amp;locale=en_US&amp;trk=tyah">David Obermann</a> for organising the event.</p>
<p>Looking forward to seeing you in Berlin.</p>

    <title>Inductive Bias: Dorkbot Berlin</title>

      <div xmlns="http://www.w3.org/1999/xhtml"><p>c-base - 8p.m. on a Monday evening - the room is packed (and pretty cloudy as well): Time for <a href="http://www.dorkbot.org/dorkbotbln/">Dorkbot</a>, a short series of talks on &#8220;People doing strange things with electricity&#8221; hosted by Frank Rieger.</p>
<p>First talk up on stage was Gismo on <a href="https://m21.hyte.de/planet/">Raumfahrtagentur</a> - a Berlin maker-space located in Wedding. Originating from the presenter&#8217;s interest in electrical bikes a group of ten people interested in hardware hacking got together. Projects include but are not limited to 3D printing, 3D scanning, textile hacking, a collaborative podcast. Essentially the idea is to provide room and infrastructure to be used collaboratively by a group of members. From an organisational point of view the group is incorporated as a GmbH - however none of the projects is mainly targeted to commercialization: It&#8217;s main target group are hobbyists, researchers and open hardware/software people. If interested: Each Monday evening there is a &#8220;Sunday of the Kosmonauts&#8221; where externals are invited to come visit.</p>
<p>Second talk was on the project <a href="http://meyleankronemann.de/klackerlaken/">Drinkenlights (Klackerlaken)</a> - a way for children to learn the basics of electronics without any soldering (hardware available for three Euros max). Experiences made with giving the ingredients for creating these toys to children of varying ages were interesting: From kids of about five years playing around up to ten/eleven year olds that when in school seemingly had to re-learn being creative without being given much direction or instruction on the task at hand.</p>
<p>In the third talk Martin Kaltenbrunner introduced his <a href="http://vimeo.com/35791602">Tworse Key</a> - a nice symbiosis of old technology (a morse key) and new media (Twitter). Essentially built on top of an Arduino Ethernet board it made it possible to turn morse messages into Tweets. Martin also gave a brief overview of related art projects and briefly touched upon the changes that open source and open hardware bring to art: There are projects that open all design and source code to the public to benefit from a wider distribution channel (without having to actually produce anything), working on designs in a collaborative way and get improvements back to the original project. All of these form a stark contrast to the existing idea of having one single author whose contribution is to build a physical object that is then presented in exhibitions - providing both, new possibilities and new challenges to artists.</p>
<p>In the last presentation Milosch introduced his new project <a href="http://etib.org/">ETIB</a> whose goal it is to bring hardware hacking geeks together with textile geeks to work on integrating circuits into clothes.</p>
<p>If you are interested in hacking spaces in general and what is happening in that direction in Berlin, mark this Friday in your calendar: c-base will be hosting a <a href="http://blog.hackerspaces.org/2012/01/13/upcoming-symposium-in-berlin-germany-hackerspaces-the-story-so-far-and-the-future-ahead/">Hackerspace meetup</a> - so if you want to know how hackerspaces work or want to create one yourself, this event might be interesting to you.</p>

<p>Heute auf den Tag genau gibt es meinen Blog <strong>7</strong> Jahre. Denn einst in der eisigen Januarkälte des Jahres 2005, erblickte mein Blog das Licht der Welt. Ich hatte damals keine Ahnung worauf ich mich einlassen würde und ob ich den Anforderung gewachsen wäre. Doch mittlerweile is es aus dem Gröbsten heraus und bereitet mir Freude. Einzig die gelegentlichen Spam-Kommentare nerven etwas, aber dafür gibt es zum Glück ein paar wirksame Mittelchen.</p>
<p>Gut, es ist auch etwas eitel, hat Sonderwünsche und verlangt hin und wieder nach einem neuen Gewand, aber ich hab es lieb gewonnen.</p>

<p>Gestern hatten wir Zeit, Kinokarten und gemütliche Plätze im <em>Sergio Leone</em> Saal des Filmtheaters <a href="http://www.schauburg-dresden.de/">Schauburg</a>. Es lief der Film <a href="http://www.ziemlichbestefreunde.senator.de/">Ziemlich beste Freunde</a>.</p>
<p>Ein einfach schöner und lustiger Film. Und während ich mir gerade so überlege was ich hier weiter schreiben könnte, trudelt ein Artikel mit genau dem selben Thema im Feedreader ein.</p>

    <title>Inductive Bias: Scrumtisch Berlin</title>
    <id>http://blog.isabel-drost.de/index.php/archives/362/scrumtisch-berlin</id>
    <link href="http://blog.isabel-drost.de/index.php/archives/362/scrumtisch-berlin" rel="alternate" type="text/html"/>
    <link href="http://blog.isabel-drost.de" rel="via" type="text/html"/>
    <content type="xhtml">
      <div xmlns="http://www.w3.org/1999/xhtml"><p>After quite some time off I went to the <a href="http://www.scrumtisch.net">Scrumtisch</a> Berlin. The event was incredibly well visited - roughly 50 people filled the upper floor at Cafe Hundertwasser. Today&#8217;s event was organised such that participants first collected discussion topics, prioritised them together and then discussed the top three items in a timebox of 15 minutes each.</p>
<p>Topics collected were:</p>
<ul>
<li>Best tricks to make teams self organised (20 votes)
</li><li>What is QA doing fulltime in a team (13 votes)
</li><li>Ops and planning in a team (15 votes)
</li><li>PO disappears and takes backlog and vision with him - what now? (7 votes)
</li><li>Working with non-Software teams (17 votes)
</li><li>Pimp up my retrospective (12 votes)
</li><li>Multiple teams on one projects and vice versa (4 votes)
</li><li>IBM doing Scrum/ massive Scrum (9 votes)
</li><li>Feature knowledge vs market knowledge - what is more important in a PO if you have to choose due to people constraints (9 votes)
</li><li>How to convince a team to do more (3 votes)
</li><li>Why is agile good (10 votes)
</li></ul>
<p>Compared to previous meetings quite some topics repeat. About half of the attendees were there for the first time - so it seems there is a common set of questions people usually run into when rolling out Scrum.</p>
<h2>Self organising teams</h2>
<p>Seems like this is one of the most common questions run into when rolling out Scrum - how to really get to self organising teams. The question can be answered from two positions: What are the pre-requisites it takes to enable teams to become self organising? How to actually transform teams that are used to a command and control structure and are reluctant to transform?</p>
<p>The discussion, mainly led by <a href="http://www.agile42.com/training/csm-training-berlin-012012/">Andrea Provaglio, CSM trainer</a> focussed mainly on the first part of the question. Even when limiting discussion that way, the answer will still depend heavily on the organisation structure, number of management levels, team sizes.</p>
<p>Marion made the topic a bit more concrete: Given the <a href="http://www.telegraph.co.uk/finance/newsbysector/mediatechnologyandtelecoms/7945719/Netflix-lets-its-staff-take-as-much-holiday-as-they-want-whenever-they-want-and-it-works.html">flexible vacation planning approach</a> of Netflix, her question was whether that sort of loose approach could work in a typical German company (after all we have 30 instead of <20 vacation days, we have fixed holidays, she as a C?O of course wants to avoid customers being left alone when the whole team is on vacation.) Andrea re-phrased agility a bit here. His proposal was to not allow people to take their time off just anytime but to give them the freedom to figure out when to take time off. He identified five principles for leadership:</p>
<ul>
<li>Clearly setting a goal (in that case: Everyone needs to have a vacation plan at a given date.)
</li><li>Provide the team with all resources, information and with the environment they need to accomplish their task.
</li><li>Define constraints (&#8221;there must be at least one guy in the office on any given working day&#8221;)
</li><li>Check back regularly
</li><li>Make yourself available to answer any questions
</li></ul>
<p>The discussion on teams reluctant to adopt self organisation was separated out and deferred. His point was mainly about enabling and encouraging self organisation. Enforcing self organisation however is not possible.</p>
<h2>Scrum in non-Software teams</h2>
<p>Though phrased very broadly the topic quickly turned into a &#8220;how to do Scrum for hardware&#8221; discussion. Main problem here is that the further down you go the longer design generally takes. Even just routing lines on one decently sized circuit board can take several weeks. Mainly three possible ways out of the problem emerged from the discussion:</p>
<ul>
<li>Loosening the definition of done - &#8220;potentially shipable&#8221; may not mean sellable or even really shipable. I don&#8217;t think one should go down that slippery path. Only by actually shipping can I get the feedback I need to improve my design. So instead of loosening the definition of done we should instead start thinking about ways to get faster feedback, reduce risk and introduce shorter iterations.
</li><li>Another way is to look for ways to reduce iteration length, even though we might not get down to software release cycles, and align releases such that integration can happen earlier.
</li><li>The third way out could be to realize that maybe Scrum does not quite fit that way of working and use a different process instead that still provides the transparency and fast feedback that is needed (think Kanban).
</li></ul>
<p>Overall the most important result of the discussion was that within 15min discussion the issues cannot be solved. After all the solution will depend on what exactly you are working on, who your suppliers are and what your team looks like. Most important is to recognize that there is a problem and to work on removing that impediment - most important is to identify issues and to improve your process.</p>
<h2>Operations and planning in Scrum</h2>
<p>The last question discussed involved operations and Scrum planning: Given a team that does software development but is interrupted frequently with production issues - how should they work in a Scrum environment.</p>
<p>There are multiple facets to that problem: When it comes to deciding whether to deal with something immediately or not it makes sense to weigh size of the issue against amount of work it takes to resolve it. &#8220;Getting things done&#8221; states that the minimum size of an issue to deal with instantly is 2min of work. Issue with that is that the assumption of GTD was that issues flow into and inbox that is dealt is when there is time. In production environments however these issues usually trickle in instantly interrupting developers over and over again incurring a huge cost due to task switching.</p>
<p>One way out might be to have an event queue and assign developers (on a rotating basis) to deal with the issues and leave time for others to work in a focused way. Make sure to rotate frequently instead of by sprint - otherwise you run into the problem of making the team unstable thus delivering no stable amount of business value each sprint.</p>
<p>Another obvious way is to account for frequent interruptions and include a buffer for those in your plan. The most important benefit of that approach is to make the cost of this working mode clearly visible to management - leaving the decision how to deal with it up to them.</p>
<p>Other simple fixes include introducing some level of indirection between the actual developer and the customer raising the issue, documenting solutions as well as incoming issues for better visibility, introducing a single point of contact capable of prioritising.</p>
<p>Coming back to vanilla Scrum however there is one interesting observation to be made: The main contract with iterations is for developers to be able to work in a focused way. Instead of having their tasks switched each day they are promised a fixed period of time to solve a given set of stories. In the end a sprint is a compromise between what management may need (change their mind on what is important frequently) and what developers need (working on a set of defined tasks not interrupted by re-priorisation). If the assumption of focus does not longer hold true, Scrum might be the wrong model. If what needs to be done changes daily, Kanban again might be the better option. Still making sure that the cost of task switching is visible is vitally important.</p>
<p>To sum up a very interesting Scrumtisch - in particular as agile methods really seem to become more and more common also in Berlin. Speaking of challenges: As user groups grow sometimes their character changes as well, in particular when built around participation and discussion. It will be interesting to watch Scrumtisch deal with that growth. Maybe at some point splitting the audience and having separate breakout sessions might make sense. Admittedly I&#8217;d also love to know more on the background of the audience: How many are actually using Scrum in the trenches vs. teaching Scrum as coaches? How long have they been using Scrum? In what kind of organisation? Maybe a topic for next time.</p>

    <title>Inductive Bias: Teddy in Chicago</title>
    <id>http://blog.isabel-drost.de/index.php/archives/360/teddy-in-chicago</id>

    <content type="xhtml">
      <div xmlns="http://www.w3.org/1999/xhtml"><p>Last week I spent several days in Chicago mainly to attend a few meetings at the local Nokia/Navteq office. Though the schedule was pretty packed, a few hours remained to explore the then frosty and windy city:</p>
<p /><center><br />
<img src="http://isabel-drost.de/Bilder/wordpress/chicago_2012.jpeg" /><br />
<small>Top three images: Some impressions of the city. Bottom left: Teddy&#8217;s new friend. Bottom right: Situation at ORD when flying out - fortunately both, the airport as well as the airline (Swiss) have quite some experience with challenging weather conditions so that we could leave without too much delay. </small><br />
</center>
<p>As usual I wondered whether there are any Apache people close by. So before flying in I checked <a href="http://people.apache.org/map.html">our committers map</a>. As there were a few people in that general area I sent a brief heads-up to the greatly under-advertised, private, non-archived, committers only list <a href="http://mail-archives.apache.org/mod_mbox/www-community/200310.mbox/%3C011601c39367$686b8fa0$7500a8c0@goliath%3E">party@apache.org</a>. In case you&#8217;ve never heard about it: The main use case of that list is to provide a means for committers to arrange for meeting up with fellow Apache people and share travel details.</p>
<p>As a result I received a brief list of things to do in Chicago and got to attend a small but really nice meetup. Having a means to get in touch with locals can make such a difference - thanks for the warm welcome! Hopefully next time I&#8217;m there weather is as warm - would love to explore the (at least according to my travel guide book) beautiful nature of the great lakes.</p>

      <div xmlns="http://www.w3.org/1999/xhtml"><blockquote><p>“Agile and Lean have a single purpose: to continually challenge the status quo. If you’re not doing that, you’re probably an impediment to it.” </p></blockquote>
<p> <a href="http://www.agile42.com/en/blog/2011/12/22/agile-lean-i-wish-it-would-be/">agile42.com</a></p>
<p>Judging from the way some people become overly careful when discussing agile in general and Scrum in particular in my presence I seem to slowly have built up a reputation for being a strong proponent of these methods. Given the large number of flaky implementations as well as misunderstandings it seems to have become fashionable to blame Scrum for all badness and dismiss it altogether - up to the point where developers are proud to finally having abandoned Scrum completely -  so that now they </p>
<ul>
<li>can work in iterations,
</li><li>accept new tasks only for upcoming but not for the current iteration,
</li><li>develop in a test-driven way,
</li><li>have daily sync meetings,
</li><li>mark tasks done only when they are delivered to and accepted by the customer,
</li><li>have regular “how to improve our work” meetings,
</li><li>estimate tasks in story points and only plan for as much work per iteration as was done in the past iteration
</li></ul>
<p>… my personal take on that: Add in regular releases and you end up with a pretty decent scrum/agile implementation, no matter what your preferred name for it may be. Just for clarification: Though very often I write about what I call Scrum, I don’t use that particular method just because it is the latest fashion. It simply is a tool that has served me well on multiple occasions and given me working guidelines when I had no idea at all what software development in a professional setting should look like.</p>
<p>So where does all that friction with anything Scrum, agile, lean or whatever you call it come from? Recently I came across a blog post that  <a href="http://www.jillesvangurp.com/2011/12/03/scrum-agile-madness/">jillesvangurp.com</a> nicely identified some grave issues with current Scrum adoption. Unfortunately the blog post only lists the failures without going into a deeper analysis of the actual defects <a href="http://books.google.com/books?id=E5uIKu9Y8UEC&amp;lpg=PA129&amp;ots=tXpP4xb8V6&amp;dq=scientific%20debugging&amp;pg=PA18#v=onepage&amp;q=%22Bugs,%20faults,%20or%20defects?%22&amp;f=false">causing those failures</a>.</p>
<p>First of all, lets assume as working hypothesis that Scrum in itself does not solve any issues in your organisation but is a great tool to uncover deficiencies. The natural conclusion should be to use it as a tool to discover problems, but search for solutions for these problems elsewhere.</p>
<p>With that hypothesis, lets discern the the issues discussed in the post above and assign them to  one of three defect categories.</p>
<p><b>Category one: Issues with the team</b></p>
<p><b>Problem:</b> You have a team of all-junior developers, or of all-mediocre developers.</p>
<p><b>Goal:</b> Turn them into a high performing team.</p>
<p><b>Solution:</b> Imagine you were not using Scrum at all, what would be the ideal solution? Well the obvious route probably is to re-adjust the team, add several seniors so that you end up with the right mix of people that have experience and share a vision - juniors than can learn and adapt what works from them.</p>
<p>Comparing that to our hypothesis: Scrum is all for short delivery cycles. You will uncover teams that perform badly much faster than in methods with longer iteration periods. So it should be reasonably simple to figure out teams that have a dysfunctional configuration. Changing that configuration however no longer is dictated by Scrum.</p>
<p><b>Category two: Bugs introduced during Scrum roll-out</b></p>
<p>The failures discussed in the blog post include people following Scrum mechanically: Only because your developers are moving post-it notes from left to right does not mean they are doing anything agile. It’s perfectly possible to do <a href="http://www.forrester.com/rb/Research/water-scrum-fall_is_reality_of_agile_for_most/q/id/60109/t/2">waterfall in Scrum</a>. Whether that helps solve any of your issues is a different matter.</p>
<p>Instead of mechanically going through the process what is more important is to understand the reasons and goals of each of the pieces that form Scrum. To make a rather far fetched comparison: </p>
<p><iframe allowfullscreen src="http://www.youtube.com/embed/d2afuTvUzBQ" frameborder="0" height="315" width="420"></iframe></p>
<p>When introducing Scrum without a deep understanding of why each piece is done, what you end up with is people following that process without understanding the meaning of each step. They end up mimicking behaviour without knowing the real world: To some extend seeing only the shadows of good development patterns without understanding the real items producing these shadows.</p>
<p>As a general rule: Understand why there is a retrospective meeting, remember why you need estimations, think about why there are daily stand-ups (instead of weekly meetings, instead of daily sit-togethers, instead of hourly stand-ups). Figure out why there is  a product owner, what the role of a scrum master does. Pro-Tip: As soon as you really have understood Scrum, you don’t need a checklist of all meetings to hold for a successful iteration - they will just fit in naturally. If they don’t, you are probably missing an important piece of the puzzle - rather than rely on a pre-fabricated checklist, go bug your trainer or coach with questions to better understand the purpose of all the different bits and pieces. </p>
<p>One very grave bug on roll-out is the general believe that Scrum is equal to a little bit of fairy dust you spread over your teams and all problems will automatically be solved afterwards. It is not - it’s not a silver bullet, it’s not fairy dust, it’s no magic - such things exist in fairy tales but have been seen nowhere in the real world. According to our working hypothesis above however Scrum does something really magical: By shortening delivery cycles it introduces short feedback loops which make it very easy to uncover problems in your organisation way faster than people are able to cover them up and hide them. Finding a solution on the other hand is still up to you.</p>
<p>The last roll-out issue mentioned is that of crappy certification - current certification programs are designed such that the naive organisation may believe that after two days of training their employers will magically turn into super heroes. Guess what - as with any certification training is just the very first step. Actual understanding comes with experience. Compare that to learning to drive: Only because you managed to get a drivers license does not turn you into a formula one winner. Instead that requires a whole lot of training. Same applies for any Scrum Master or Product Owner.</p>
<p><b>Category three: Organisation specifics</b></p>
<p>All other issues with Scrum mentioned in the blog post are either specific to the broken structures in the organisation under investigation or due to general Scrum mis-conceptions. Leaving these aside here.</p>
<p>To sum up: Scrum to me is nothing but a term to summarize good, proven development practices. I don’t care how you name them - however having any one name that is well defined makes it way easier to communicate. Scrum is not silver bullet - it does not solve all the issues your organisation may have. However it is a very effective debugger uncovering the issues employees and managers are trying to cover up. If you know all those issues very precisely already or you are certain that you don&#8217;t have any, chances are you <a href="http://blogs.gartner.com/david_norton/2011/01/16/will-2011-see-our-love-affair-with-scrum-end/">don&#8217;t need Scrum</a>.</p>

      1989 erschien die erste Version der <a href="https://de.wikipedia.org/wiki/GNU_General_Public_License">GNU General Public License</a>, veröffentlicht von Richard Stallman. Er wollte, dass Softwarequellcode offen bleibt, modifiziert und weitergegeben werden darf. Der Anwender sollte die volle Kontrolle über seine Hardware behalten und das meiste aus Software machen können.
  </p><p class="">
      Heute, 23 Jahre später, sieht die Realität anders aus: Apple wird für sein Konzept des Appstores bejubelt: Damit alles aus einer Hand kommt und sich gut integriert, geben Nutzer immer mehr Kontrolle über ihre gekauften Systeme ab. Und es wird zum herstellerübergreifenden Trend. Ein goldener Garten für den Endnutzer? Zumindest so lange, wie dieser nicht andere Welten erkunden möchte. Oder gar zu nicht vorhergesehenen Zwecken gebrauchen möchte.

      Wo Cory Doctorow mit seinem Vortrag <a href="http://youtu.be/HUEvRyemKSg">"The coming war on general computation" auf dem 28c3</a> aufgehört hat, wollen wir weitermachen und mit euch diskutieren. Was bedeutet es, wenn wir immer weiter die Kontrolle über unsere Geräte verlieren? Welche Chancen bringt es? Welche Risiken birgt es? Warum interessieren sich 99% der Nutzer nicht für Freie Software?
 </p><p class="">
     Um Richard Stallman zu verstehen, geben wir einen kurzen Rückblick auf die Entstehungsgeschichte der GNU Public License, um die Frage zu klären, was Freie Software bedeutet und warum wir Freie Software benutzen sollten. Und gerne beantworten wir natürlich auch eure Fragen.

<p>Über <a href="http://www.golem.de/1201/89207.html">Golem</a> bekam ich gerade mit, dass es jetzt den Editor <a href="http://www.vim.org/">Vim</a> auch für iOS gibt. Es ist eine kostenfreie universelle Version für einen iPod touch, ein iPhone oder ein iPad.</p>
<ul>
<li><a href="http://applidium.com/en/applications/vim/">Applidium: Vim</a></li>
<li><a href="http://itunes.apple.com/app/vim/id492668168">Appstore Direktlink</a></li>
</ul>
<p>Mir scheint, die Vim iOS App ist für aktuelle hochauflösende Displays optimiert. Bei meinem ollen iPod touch kommen die Buchstaben in der Standardgröße nur in Bruchstücken an. <img class="wp-smiley" src="http://blog.tigion.de/wp-includes/images/smilies/tango_face-monkey.png" alt=":monkey:" /> </p>
<p>Aber gut zu wissen, dass man den Vim nun auch mit entsprechendem iOS Gadget immer am Man(n) haben kann. Die Usability und der Nutzen ist zwar etwas, vorsichtig ausgedrückt, <em>beschränkt</em> &#8230; aber he es ist der Vim. <img class="wp-smiley" src="http://blog.tigion.de/wp-includes/images/smilies/macinacs_hehee.gif" alt=":hehe:" /> </p>

<p>Erinnerungen an die Ostsee 2010.</p>
<p><em>Dieser Beitrag ist gleichzeitig ein Test für zwei neue Features hier im Blog. Denn ich bastel gerade an einer Lösung, um zum Einen mehrere große Fotos einzubinden, bisher war nur eines möglich, und zum Anderen, dass nun auch sehr sehr breite Fotos möglich sind.<br />
Die hier gezeigten Fotos haben eine maximale Breite von 1600px, so dass sich auf einem 22&#8243; Monitor das Betrachten im Fullscreen durchaus lohnt. Ist das Browserfenster zu klein, passen sich die Fotos an.</em></p>
<p>Eine nicht unbedingt neue Besonderheit ist, dass die großen Fotos nur hier im Blog groß kommen. Also im Feedreader den Fullfeed lesen ist ok, aber die großen Fotos gibt es nur hier im Blog in groß zu sehen. <img class="wp-smiley" src="http://blog.tigion.de/wp-includes/images/smilies/macinacs_smile.gif" alt=":)" /> </p>
<p><small><del datetime="2012-01-19T21:19:12+00:00">EDIT: Ich sehe gerade, im Feed kommen jetzt gar keine Bilder mehr. Die Änderung hat doch ungewollt Auswirkung auf den Feed. Hier muss ich noch Nachbessern.</del> &#8211; gelöst!</small></p>

    <title>Inductive Bias: Reasons for you to visit Berlin Buzzwords</title>
    <id>http://blog.isabel-drost.de/index.php/archives/358/reasons-for-you-to-visit-berlin-buzzwords</id>
    <link href="http://blog.isabel-drost.de/index.php/archives/358/reasons-for-you-to-visit-berlin-buzzwords" rel="alternate" type="text/html"/>
    <link href="http://blog.isabel-drost.de" rel="via" type="text/html"/>
    <content type="xhtml">
      <div xmlns="http://www.w3.org/1999/xhtml"><p>I&#8217;ve heard of several people who are not quite sure yet whether they should visit Berlin Buzzwords or not - in particular when having to travel far and cross 9 time zones to attend. My general recommendation is to plan to spend some more days in Europe. The conference is conveniently scheduled on Monday and Tuesday which gives you one weekend before to explore the city and the whole week afterwards to go and see more either in the city or around.</p>
<p>In case you are wondering whether the city is a worthy destination when travelling with children - below is a list of things to do and places to go I sent to someone recently. Hope it helps with your decision as well. In general the city is pretty green, there are several locations specially amenable to a visit with kids - so treat the list below as what it is: An incomplete listing of some of the most obvious locations that might be of interest collected by someone who knows a few parents and their children. Also in case you speak German make sure to check out one of the many <a href="http://www.amazon.de/Berlin-mit-Kind-TIP/dp/3832196552/ref=sr_1_1?ie=UTF8&amp;qid=1326486808&amp;sr=8-1">guide books for Berlin with children</a> available in local book stores - <a href="http://www.kulturkaufhaus.de/">Dussmann</a> and <a href="http://www.hugendubel.de/">Hugendubel</a> generally have the largest selection though <a href="http://www.chatwins.de/">Chatwins</a> is my preferred one for anything about travelling.</p>
<h2>In the city</h2>
<p>In case of good weather:</p>
<ul>
<li><a href="http://blog.isabel-drost.de/index.php/archives/358/reach-us.html?L=1">Tierpark Berlin</a> - make sure you visit Tierpark (not Zoo) - it&#8217;s much larger and friendlier. See also <a href="http://www.flickr.com/photos/photomic/sets/72157607924734514/">images taken by Berlin Buzzwords fotographer Philipp</a>, <a href="http://www.flickr.com/search/?w=all&amp;q=tierpark&amp;m=text">general images</a>.
</li><li>There is a huge park in walking distance of Brandenburger Tor: <a href="http://www.flickr.com/search/?w=all&amp;q=tiergarten+berlin">Tiergarten</a> for recreation after sight seeing.
</li><li>For swimming head over to either <a href="http://www.flickr.com/search/?w=all&amp;q=wannsee">Wannsee</a> or <a href="http://www.flickr.com/search/?w=all&amp;q=schlachtensee">Schlachtensee</a>
</li><li>For exploring a NSA listening station head west to <a href="http://en.wikipedia.org/wiki/Teufelsberg">Teufels</a>-<a href="http://www.flickr.com/photos/photomic/sets/72157607924774440/">berg</a>
</li><li>On warm evenings plan for some time at <a href="http://tinyurl.com/bslwfvm">Maybachufer</a>
</li></ul>
<p>For bad weather:</p>
<ul>
<li>If your kids like tech go to <a href="http://www.sdtb.de/Home.623.0.html">Technik</a> <a href="http://www.flickr.com/search/?w=all&#038;q=technikmuseum<br />
">Museum</a> (it features one of the first computer (the one built by Zuse that is))
</li><li>If you kids like nature go to <a href="http://www.naturkundemuseum-berlin.de/en/">Naturkunde</a> <a href="http://www.flickr.com/search/?w=all&amp;q=naturkundemuseum">Museum</a>
</li><li>If you are interested in science - make sure to be here for the <a href="http://www.langenachtderwissenschaften.de/index.php">long night of science</a> (web page may need google translate unless you speak German.)
</li><li>For a city tour check out the following <a href="http://g.co/maps/en28h">scribbles</a> - they also include some interesting parts of the bus line 100 and 200
</li></ul>
<h2>Close to the city:</h2>
<p>If you have some more time to spend make sure you also explore the closer surroundings:</p>
<ul>
<li>80km north: rent a canoo and explore <a href="http://www.flickr.com/search/?w=all&amp;q=mecklenburg+canoe&amp;m=text">Mecklenburg</a>
</li><li>200km north: visit <a href="http://www.flickr.com/search/?w=all&amp;q=ruegen">Rügen</a>, spend some time swimming, some time to see the amazing chalk cliffs, some time to see the isle by bike
</li><li>250km south: <a href="http://www.flickr.com/search/?w=all&amp;q=elbsandsteingebirge">go hiking</a> or rafting in Elbsandsteingebirge
</li><li>80km south: rent a canoo and explore the <a href="http://www.flickr.com/search/?w=all&amp;q=spreewald+canoe&amp;m=text">canals in Spreewald</a>
</li></ul>
<p>Hope to see you in Berlin in June. If you need more information or recommendations don&#8217;t hesitate to ask. </p>
