Recap of the Schneide Dev Brunch 2014-06-01

June 2, 2014

brunch64-borderedYesterday, we held another Schneide Dev Brunch at last. The Dev Brunch is a regular brunch on a sunday, only that all attendees want to talk about software development and various other topics. If you bring a software-related topic along with your food, everyone has something to share. The brunch was very well-attended this time. We had bright sunny weather and used our roof garden to catch some sunrays. There were lots of topics and chatter. As always, this recapitulation tries to highlight the main topics of the brunch, but cannot reiterate everything that was spoken. If you were there, you probably find this list inconclusive:

Home office in another time zone

One of our attendees is preparing to leave Germany for at least one year to work in another timezone one the same projects. He gave a quick overview about the setup and some considerations. The team is used to distributed, multi-timezone work, but will now span the whole scala of it. We are eager to have a first-hand report about how it all plays out and sad that we will not see him for quite a time in person. (Personal note: I will miss the developer beer meetings we held infrequently)

XP 2014 conference in Rome

Another one of our attendees just came back from the XP 2014 conference in Rome, still hungover. She reported a lot of impressions and single bits of insights impromptu and will work up a more refined talk for the next brunch. One thing that seems like a really good idea is the “Stop Work Authority Card”. Basically, it’s a card you can hold up like a referee in a sports match to clearly state that the safety of some of your most valueable assets is compromised or risking to be. You have the obligation to play the card if you perceive such a threat and the (temporary) authority to remove it or have it removed.

The idea of “safety” (in non-hazardous or friendly) was a big theme at the conference. The claim that “safety is the prerequisite of excellence” stood out.

The XP 2014 conference was a small one, but visited by insiders from all over the world. It certainly sparked a lot of ideas and food for thought. We are looking forward for the report at the next Dev Brunch.

Is TDD dead?

A most recent discussion we at the Softwareschneiderei follow with great interest is the debate around David Heinemeier Hansson’s frontal attack on the hype around Test Driven Development. There are lots of blog posts to read, some better, some not so much. But an highlight is probably the video chat series between Kent Beck (inventor of TDD), Martin Fowler (general loudmouth, here in a rather quiet role as a moderator) and David Heinemeier Hansson (general firestarter). And while the topic is hot and the discussion fresh, we soon deviated from the main questions and explored the state of art how knowledge and experience is transported in our profession. We concluded that while we all dislike populism, it’s an effective tool to transport messages (with the downside of losing nuances on the way).

Continuous improvement

One attendee asked about good ways to improve his skill and craft. Besides the obvious answers (sleep less, train more, read a lot), there were quite a few ideas. One source of inspiration could be “Jiro Dreams of Sushi”, a documentary movie about a famous sushi master and his quest to perfect the art of sushi (yes, the little snacks that are delicious even without mastery). The concept of “better every day, but never good enough” was identified to be prone to perfectionism, a trait often found in masters of their field, but probably not the most economically sound one. The author of this blog post wrote about his approach to professional passion three years ago.

Radical table

We agreed to consider our little discussion group “the radical table” because we don’t shy away from argueing in the extremes to get our messages across. This all was mentioned in good spirits and without personal insults. But if you read about the “radical table manifesto” some point in the future, don’t be surprised. It might include a plea to Uncle Bob to never give up his style to deliver keynotes and talks even if we don’t attend it twice.

Start-up software tools

In the end of the brunch, we split into several smaller groups to discuss more specific topics of personal interest. I can’t report for the talks I didn’t attend, but joined a discussion about recommendable and necessary tools for a software development start-up company. Some tools that were given included OpenERP, JIRA (including the whole Atlassian portfolio), FogBugz, Microsoft Office 365 and CAS Genesis World.

One controversial topic was the importance of integration (as in “one tool for everything”) versus requirement matching (as in “does exactly what we want”). Related was the topic of “plan ahead” versus “change tools mid-flight”. If you have experience with these questions, please leave a comment.

Epilogue

As usual, the Dev Brunch contained a lot more chatter and talk than listed here. The high number of attendees makes for an unique experience every time. We are looking forward to the next Dev Brunch at the Softwareschneiderei. And as always, we are open for guests and future regulars. Just drop us a notice and we’ll invite you over next time.


Summary of the Schneide Dev Brunch at 2013-03-03

May 13, 2013

brunch64-borderedYes, you’ve read it right in the title. The Dev Brunch I want to summarize now is over two month ago. The long delay can only partially be explained by several prolonged periods of illness on my side. So this will be a rather crisp summary, because all the lively details have probably vanished by now. But let me start by explaining what the Dev Brunch is:
The Dev Brunch is a regular brunch on a sunday, only that all attendees want to talk about software development and various other topics. If you bring a software-related topic along with your food, everyone has something to share. This brunch was very well-attended, but we still managed to sit around our main table. Let’s have a look at the main topics we discussed:

XFD presentation

In a presentation of a large german software company, our Extreme Feedback Devices were thoroughly mentioned. We found it noteworthy enough to mention it here.

Industrial Logic’s XP Playing Cards

This is just a deck of playing cards, but not the usual one. One hundred different cards with problems, solutions and values wait for you to make up some game rules and start to play. The inventors have collected a list of possible games on their website. It leads to hilarious results if you just distribute some cards in a group of developers (as we did on the brunch) and start with a problem. Soon enough, your discussion will lead you to the most unexpected topics. We ended with the “Power Distance Index“, but I have no recollection how we got there. These cards are a great facilitator to start technical discussions. They seem to be non-available now, sadly.

Distributed SCRUM

A short report on applying SCRUM to a multi-site team, using desktop sharing and video chat software. The project landscape is driven by an adaption of “scrum of scrums”. I cannot dive into details anymore, but these reports are a great reason to really attend the brunch instead of just reading the summary. The video chat meetings were crucial for team-building, but very time-consuming and wearying due to timezone reasons.

SCRUM User Group Karlsruhe

Speaking of SCRUM, there is a SCRUM User Group in our city, Karlsruhe in Germany. It might not be the biggest user group ever, but one attendant of our brunch reported that all participants are “socially very pleasing”. There are very interesting presentations or gatherings for specific topics. If you have to deal with SCRUM, this should be on your agends.

Retrospectives

We had a prolonged talk about retrospectives and how to apply them. Most retrospective activities tend to be formalized (like “cards and priorities”) and lose effectiveness due to the “comfort aspect”. A hypothesis during the talks was that when moderation isn’t necessary anymore, its more likely to be a negative smell. We talked about moderated vs. non-moderated retrospectives quite a bit, also exploring the question what role should/could be moderator and why. The “Happiness Metric” was mentioned, specifically its application by the swedish company Crisp, as described by Henrik Kniberg. Some sources of ideas for retrospectives were also mentioned: the Facilitator Gathering or some noteworthy books that I forgot to write down (sorry! Please ask for them in the comments).

Internal facilitator

We also discussed some problems that “internal” facilitators face day-to-day. Internal facilitators work within the team they try to facilitate.

Presentation about acceptance testing by Uncle Bob

A big event in February this year were the workshops and the presentation with Robert C. Martin about testing. His talk presented Fitnesse in the context of acceptance testing. There was some confusion about the amount of available seats, so most of us didn’t attend (because we weren’t able to register beforehands). Some of our participants were there, nonetheless and found the presentation worthwile. Only the usual pattern of Uncle Bob’s presentation lacked some virtue this time, but this can easily explained with the flu. Here’s an external summary of the event. Check out the comment section for potential first-hand accounts.

Definition of test types

In the wake of our talk about Uncle Bob’s presentation, we discussed different test categorization schemes. We’ve invented our own, but there is also a widely used definition from the International Software Testing Qualifications Board. We didn’t dive deep into this topic, so lets say it’s still open for discussion.

Book about money counterfeiter

Somehow, I’ve written down a notice about a german book about a famous money counterfeiter, Jürgen Kuhl: “Blütenträume”. This talented artist drew dollar notes by hand so perfectly that even experts couldn’t tell them apart. Regrettably, I don’t remember the context anymore. It might have something to do with Giesecke & Devrient, a manufacturer of money printing machines. But even then, I don’t remember what that context was about.

Traceability of software artifacts

Our last topic circled around the question how software artifacts are registered and traced in our practice. The interesting part of this question is the ability to make connections between different artifacts, like an automatic report about what existing features are tangented by a change and should be tested again (if manual tests are necessary). Or you want to record the specifics of your test environment alongside your tests. Perhaps you are interested in the relation between features and their accompanying tests. The easiest connection can be made between a change (commit) and the issue it belongs to. But changes without issue (like almost all refactorings) are problematic still. It was an interesting discussion with a lot input to think about.

Summary

One thing I’ve learnt from this Dev Brunch is that it isn’t enough to write down some notes and try to remember the details some weeks later. The summaries have to be written in a timely manner. I didn’t succeed with it this time and try to blame it on my lack of health. I promise a better summary next time. The worst part is that I know that I’ve forgotten a lot of important or interesting details (like a youtube channel about ideas – please provide the link in the comment section, Martin!) but cannot recreate the memories.

As usual, the Dev Brunch contained a lot more chatter and talk than listed here. The high number of attendees makes for an unique experience every time. We are looking forward to the next Dev Brunch at the Softwareschneiderei. And as always, we are open for guests and future regulars. Just drop us a notice and we’ll invite you over next time.


Summary of the Schneide Dev Brunch at 2013-01-06

January 7, 2013

brunch64-borderedYesterday, we held another Schneide Dev Brunch. The Dev Brunch is a regular brunch on a sunday, only that all attendees want to talk about software development and various other topics. If you bring a software-related topic along with your food, everyone has something to share. The brunch had less participants this time, but didn’t lack topics. Let’s have a look at the main topics we discussed:

Sharing code between projects

The first topic emerged from our initial general chatter. What’s a reasonable and praticable approach to share code between software entities (different projects, product editions, versions, etc.). We discussed at least three different solutions that are known to us in practice:

  • Main branch with customer forks: This was the easiest approach to explain. A product has a main branch where all the new features are committed to. Everytime a customer wants his version, a new branch is created from the most current version on the main branch. The customer may require some changes and a lot of bug fixes, but all of that is done on the customer’s branch. Sometimes, a critical bug fix is merged back into the main branch, but no change from the main branch is transferred to the customer’s branch ever. Basically, the customer version of the code is “frozen” in terms of features and updates. This works well in its context because the main branch already contains the software every customer wants and no customer wants to update to a version with more features – this would be another additional branch.
  • Big blob of conditionals: This approach needs a bit more explanation. Once, there was a software product ready to be sold. Every customer had some change requests and special requirements. All these changes and special-cases were added to the original code base, using customer IDs and a whole lot of if-else statements to separate the changes from each customer. All customers always get the same code, but their unique customer ID only passes the guard clauses that are required for them. All the changes of all the other customers are deactivated at runtime. With this approach, the union of all features is always represented in the source code.
  • Project-as-an-universe: This approach defines projects as little universes without intersection. Every project stands for its own and only shares code with other projects by means of copy and paste. When a new project is started, some subset of classes of another project is chosen as a starting point and transformed to fit the requirements. There is no “master universe” or main branch for the shared classes. The same class may evolve differently (and conflicting) in different projects. This approach probably isn’t suited for a software product, but is applied to individual projects with different requirements.

We are aware of and discussed even approaches, but not with the profound knowledge of several years first-hand experience. The term OSGi was often used as a reference in the discussion. We were able to exhibit the motivation, advantages and shortcomings of each approach. It was very interesting to see that even slightly different prerequisites may lead to fundamentally different solutions.

Book (p)review: Practical API Design

In the book “Practical API Design” by Jaroslav Tunach, the founder of the NetBeans Platform and initial “architect” of its API talks about his lessons learnt when evolving a substantial API for over ten years. The book begins with a theory on values and motivations for good API design. We get a primer why APIs are needed and essential for modern software development. We learn what are the essential characteristics of a good API. The most important message here is that a good API isn’t necessarily “beautiful”. This caused a bit of discussion among us, so that the topic strayed a bit from the review characteristic. Well, that’s what the Dev Brunch is for – we aren’t a lecture session. One interesting discussion trail led us to the aestethics in music theory.
But to give a summary on the first chapters of the book: Good stuff! Jaroslav Tunach makes some statements worthy of discussion, but he definitely knows what he’s talking about. Some insights were eye-openers or at least thought-provokers for our reader. If the rest of the book holds to the quality of the first chapters, then you shouldn’t hesitate to add it to your reading queue.

Effective electronic archive

One of our participants has developed a habit to archivate most things electronically. He already blogged about his experiences:

Both blog entries hold quite a lot of useful information. We discussed some possibilities to implement different archivation strategies. Evernote was mentioned often in the discussion, diigo was named as the better delicious, Remember The Milk as a task/notification service and Google Gmail as an example to rely solely on tags. Tags were a big topic in our discussion, too. It was mentioned that Confluence has the ability to add multiple tags to an article. Thunderbird was mentioned, especially in the combination of tags and virtual folders. And a noteworthy podcast of Scott Hanselmann on the topic of “Getting Things Done” was pointed out, too.

Schneide Events 2013

We performed a short survey about different special events and workshops that may happen in 2013 in the Softwareschneiderei. If you already are registered on our Dev Brunch list, you’ll receive the invitations for all events shortly. Here is a short primer on what we’re planning:

  • Communication Through Test workshop
  • Refactoring Golf
  • API Design Fest
  • Google Gruyere Day
  • Introduction to Dwarf Fortress

Some of these events are more related to software engineering than others, but all of them try to be fun first, lessons later. Participate if you are interested!

Learning programming languages

The last main topic of the brunch was a short, rather disappointed review of the book “Seven Languages in Seven Weeks” by Bruce Tate. The best part of the book, according to our reviewer, were the interview sections with the language designers. And because he got interested in this kind of approach to a programming language, he dug up some similar content:

The Computerworld interviews are directly accessible and contain some pearls of wisdom and humour (and some slight inaccuracies). Highly recommended reading if you want to know not only about the language, but also about the context (and mindset) in which it was created.

Epilogue

As usual, the Dev Brunch contained a lot more chatter and talk than listed here. The high number of attendees makes for an unique experience every time. We are looking forward to the next Dev Brunch at the Softwareschneiderei. And as always, we are open for guests and future regulars. Just drop us a notice and we’ll invite you over next time.


Summary of the Schneide Dev Brunch at 2012-03-25

April 22, 2012

This summary is a bit late and my only excuse it that the recent weeks were packed with action. But the good news is: The Schneide Dev Brunch is still alive and gaining traction with an impressive number of participants for the most recent event. The Schneide Dev Brunch is a regular brunch in that you gather together to have a late breakfast or early dinner on a sunday, only that all attendees want to talk about software development (and various other topics). If you bring a software-related topic along with your food, everyone has something to share. We were able to sit in the sun on our roofgarden and enjoy the first warm spring weekend.

We had to do introductory rounds because there were quite some new participants this time. And they brought good topics and insights with them. Let’s have a look at the topics we discussed:

Checker Framework

This isn’t your regular java framework, meant to reside alongside all the other jar files in your dependency folder. The Checker framework enhances java’s type system with “pluggable types”. You have to integrate it in your runtime, your compiler and your IDE to gain best results, but after that you’re nothing less than a superhero among regulars. Imagine pluggable types as additional layers to your class hierarchy, but in the z-axis. You’ll have multiple layers of type hierachies and can include them into your code to aid your programming tasks. A typical use case is the compiler-based null checking ability, while something like Perl’s taint mode is just around the corner.

But, as our speaker pointed out, after a while the rough edges of the framework will show up. It still is somewhat academic and lacks integration sometimes. It’s a great help until it eventually becomes a burden.

Hearing about the Checker framework left us excited to try it sometimes. At least, it’s impressive to see what you can do with a little tweaking at the compiler level.

Getting Stuck

A blog entry by Jeff Wofford inspired one of us to talk about the notion of “being stuck” in software development. Jeff Wofford himself wrote a sequel to the blog entry, differentiating four kinds of stuck. We could relate to the concept and have seen it in the wild before. The notion of “yak shaving” entered the discussion soon. In summary, we discussed the different types of being stuck and getting stuck and what we think about it. While there was no definite result, everyone could take away some insight from the debate.

Zen to Done

One topic was a review of the Zen to Done book on self-organization and productivity improvement. The methodology can be compared to “Getting Things Done“, but is easier to begin with. It defines a bunch of positive habits to try and establish in your everyday life. Once you’ve tried them all, you probably know what works best for you and what just doesn’t resonate at all. On a conceptional level, you can compare Zen to Done to the Clean Code Developer, both implementing the approach of “little steps” and continuous improvement. Very interesting and readily available for your own surveying. There even exists a german translation of the book.

Clean Code Developer mousepads

Speaking of the Clean Code Developer. We at the Softwareschneiderei just published our implementation of mousepads for the Clean Code Developer on our blog. During the Dev Brunch, we reviewed the mousepads and recognized the need for an english version. Stay tuned for them!

Book: Making software

The book “Making software” is a collection of essays from experienced developers, managers and scientists describing the habits, beliefs and fallacies of modern software development. Typical for a book from many different authors is the wide range of topics and different quality levels in terms of content, style and originality. The book gets a recommendation because there should be some interesting reads for everyone inside. One essay was particularly interesting for the reviewer: “How effective is Test-Driven Development?” by Burak Turhan and others. The article treats TDD like a medicine in a clinical trial, trying to determine the primary effects, the most effective dosage and the unwanted side effects. Great fun for every open-minded developer and the origin of a little joke: If there was a pill you could take to improve your testing, would a placebo pill work, too?

Book: Continuous Delivery

This book is the starting point of this year’s hype: “Continuous Delivery” by Jez Humble and others. Does it live up to the hype? In the opinion of our reviewer: yes, mostly. It’s a solid description of all the practices and techniques that followed continuous integration. The Clean Code Developer listed them as “Continuous Integration II” until the book appeared and gave them a name. The book is a highly recommened read for the next years. Hopefully, the practices become state-of-the-art for most projects in the near future, just like it went with CI. The book has a lot of content but doesn’t shy away from repetition, too. You should read it in one piece, because later chapters tend to refer to earlier content quite often.

Three refactorings to grace

The last topic was the beta version of an article about the difference that three easy refactorings can make on test code. The article answered the statement of a participant that he doesn’t follow the DRY principle in test code in a way. It is only available in a german version right now, but will probably be published on the blog anytime soon in a proper english translation.

Epilogue

This Dev Brunch was a lot of fun and had a lot more content than listed here. Some of us even got sunburnt by the first real sunny weather this year. We are looking forward to the next Dev Brunch at the Softwareschneiderei. And as always, we are open for guests and future regulars. Just drop us a notice and we’ll invite you over next time.


Summary of the Schneide Dev Brunch at 2011-07-17

July 18, 2011

Last Sunday, the 17th July of 2011, we held another Dev Brunch at our company.

A Dev Brunch is an event that brings three main ingredients together: developers, food and software industry related topics. Given enough time (there is never enough time!), we chat, eat, learn and laugh the whole evening through. Most of the stories and chitchat that is told cannot be summarized and has little value outside its context. But most participants bring a little topic alongside their food bag, something of interest they can talk like 10 minutes about. This blog post summarizes at least the official topics and gives links to additional resources.

Conference review of the Java Forum Stuttgart 2011

The Java Forum Stuttgart is an annual conference held by the Java User Group Stuttgart. It’s the biggest regional Java event and always worth a visit (as long as you understand the german language). This year, the talks stagnated a bit around topics that are mostly well-known.

The best talk was given by Michael Wiedeking from MATHEMA Software GmbH in Erlangen. The talk titled “The next big (Java) thing”, but mostly addressed the history and current state of Java in an entertaining and thought-provoking way. The premise was that you have to know the past and present to anticipate the future. The slides don’t represent the talk well enough, but here’s a link anyway.

Another session introduced the PatternTesting toolkit, a collection of helper classes and useful features that enrich the development of unit testing. Alongside the other spice you can add to unit tests, this project might be worth a look. My favorite was the @Broken annotation that ignores a test case until a given date. It’s like an @Ignore with a best-before date.

There were the usual introductory talks, for example about CouchDB and git/Egit. They were well-executed, but lacked a certain thrill if you heard about the projects before.

As a personal summary, the Java world lacks the “next big thing” a bit.Two buzz products for the next year might be Eclipse Jubula (for UI testing) and Griffon (for desktop application development).

Conference review of the Karlsruhe Entwicklertag (developer day) 2011

The Karlsruhe Entwicklertag is another annual conference, spanning several days and presenting top-notch talks and sessions. It’s the first address for software developers in Karlsruhe that want to stay up to date with current topics and products.

Some topics were presented nearly identically to the Java Forum Stuttgart (but half a year earlier if that matters), while other tracks (like the Pecha Kucha talks) can only be found here.

The buzz product for the next year might be Gerrit (for code review) and Eclipse Jubula again (for UI testing).

As a personal summary, even this conference lacked a certain drive towards real new “big picture” topics. But maybe, that’s just allright given all the hype of the last years.

The GRASP principles

This topic contained hands-on software development knowledge about the nine principles named “GRASP” or General Responsibility Assignment Software Patterns/Principles. There is nothing really new about the GRASP principles, they will only give you common names for otherwise mostly unnamed best practices or fundamental design paradigms and patterns.

We even went through some educational slides that summarize the principles. The most discussion arose about the name “Pure Fabrication” for classes without a relation to the problem domain.

If you are an average experienced software developer, spend a few minutes and scan the GRASP principles so you can combine the name with the specific content.

First-hand experiences of combining work and children

We are well within the best age to raise children. So this topic gets a lot attention, specifically the actual tipps to survive the first two years with kids and how to interact with the different administrative bodies. Germany is a welfare state, but nobody claimed that welfare should be easy or logical. We’ve learned a lot about different reference dates and unusual time partitioning.

Another insight was that working less than 40 percent isn’t really worth the hassle. You are mostly inefficient and aware of it.

That’s all, folks

As always, we shared a lot more information and anecdotes. If you want to participate at one of our Dev Brunches, let us know. We are open for guests and really interested in your topics.


Follow-up to our Dev Brunch October 2010

October 31, 2010

Last Sunday , we held our Dev Brunch for October 2010. We gathered inside (no more roof garden sessions for this year) and had a good time with lots of chatter besides the topics listed below.

The Dev Brunch

If you want to know more about the meaning of the term “Dev Brunch” or how we implement it, have a look at the follow-up posting of the brunch in October 2009. We continue to allow presence over topics. Our topics for the brunch were:

  • Beyond Scrum – The first-hand tale of a local team that transformed their process to do Scrum and failed for several reasons. They finally admitted failure and search for alternatives since. Great stories of mistakes you don’t have to make yourself to learn the lessons now. We decided to transform at least some aspects of the whole story in an essay, as it’s too valuable to not be published.
  • Code Camp experiences - We already blogged about it, but this talk gave away more details and more insight from the trainer’s perspective. The speaker guided a two-day developer code camp in the spirit of code retreats with an experienced team and draw several conclusions from the event. In short: It’s well worth the time and you will see your team differently afterwards. Other attendees added their experiences with team games that reveal social structures and behaviour even quicker.
  • Local dev gossip - Yes, this is a rather unusual topic for the offical topic list, but we exchanged so much gossip talk this time that it qualifies as a topic on its own behalf. The best summarization of this topic is that there’s a lot of moving around in the local developer community, at least from our point of view. We look forward to a very exciting next year.

As there was no dev brunch in September (due to several reasons), we needed to talk about the news and rumours of two months at once. And there are a lot of things going on around here in the moment. A great brunch with lots of useful information.


Follow-up to our Dev Brunch August 2010

August 13, 2010

Last Sunday , we held our Dev Brunch for August 2010. We had to meet early in August, as there will be a lot of holiday absence in the next weeks. The setting was more classical again, with a real brunch on a late sunday morning. We had a lot more registrations than finally attendees, but it was said this was caused by a proper birthday party the night before. Due to rainy weather, we stayed inside and discussed the topics listed below.

The Dev Brunch

If you want to know more about the meaning of the term “Dev Brunch” or how we implement it, have a look at the follow-up posting of the brunch in October 2009. We continue to allow presence over topics. Our topics for the brunch were:

  • Clean Code Developer Initiative – The Clean Code Developer movement uses colored wristbands to subsequentially focus on different aspects of principles and practices of a professional software developer. Despite the name, it’s a german group with german web sites. But everybody who read Uncle Bob’s “Clean Code” knows what the curriculum is about. The talk gave a general summary about the intiative and some firsthand experiences with following the rules. If you read the book or are interested in profound software development, give it a try.
  • Non-bare repositories in git – The distributed version control system git differentiates between “bare” and “non-bare” repositories. If you are a local developer, you’ll use the non-bare type. When two developers with similar non-bare repositories (e.g. of the same project) meet, they can’t easily share commits or patches with the “push” command. This is a consequence of the “push” not being the exact opposite of the “fetch” command. If you try to synchronize two non-bare git repositories with push commands, you’ll most likely fail. The only safe approach is to introduce an intermediate bare repository or a branch in on of the repositories that only gets used by extern users. Even the repository owner has to push to this branch then. We discussed the setup and consequences, which are small in a broader use case and sad for ad-hoc workgroups.

Retrospection of the brunch

The group of attendees was small and a bit hung over. This led to a brunch that lacked technical topics a bit but emphasized social and cultural topics that didn’t make it on the list above. A great brunch just before the holiday season.


Follow-up to our Dev Brunch June 2010

June 27, 2010

Today, we held our Dev Brunch for June 2010. It was a small group of developers this time, too, as some of our usual attendees turned into parents and can’t wrap their head around anything but their kid. First things first. The good news is that today, we had a new attendee that joined our group after reading our blog articles. This time, the communication beforehands went right. Our office roof garden once again served as a great hangout place as we discussed the topics listed below.

The Dev Brunch

If you want to know more about the meaning of the term “Dev Brunch” or how we implement it, have a look at the follow-up posting of the brunch in October 2009. We continue to allow presence over topics. Our topics for the brunch were:

Google Web Toolkit, internationalization (i18n) and customer customizable text – This wasn’t a presentation, but more a discussion of different options around the fact that GWT i18n works best (and smoothest) when baked into the compiled binary. If you have a customer that wants to change every textual aspect of your projects, chances are that performance will suffer. If your job is to provide a flexible, yet powerful base product as a starting point for individual customer solutions, there’s a huge tradeoff to make here.

First-hand experience of Yoxos 5 Beta – The EclipseSource Yoxos Launcher is a cool new product that helps to keep the management overhead in setting up your IDE (eclipse as you might already have concluded) minimal. It’s a little program that downloads and sets up everything you specified in your launch profile and starts a ready-to-use eclipse instance. You can share the launch profile and keep it in sync so everybody in your group can be sure to work with the complete official setup. This talk was about a real-world use case, the unique features and the areas that still need a bit more work. Remember that it’s beta.

A book chapter review of The Passionate Programmer – The book is the second revision of the former “My Job Went To India…” book from the Pragmatic Bookshelf. It contains insights and advices on making a living in software development. It also has a focus on enterprise career planning in the IT with the background threat of outsourcing or even offshoring. Two chapters were discussed in more detail: That you should keep a map of your technology skills up-to-date (like this example) and that you really should seek to make friends with software maintainance work, as it probably will be the actual job that pays your bills.

Introduction to Code Squiggles – One of the results of a experimental quest to improve the coding style in Java are Code Squiggles. There will be a full-detail blog entry about them shortly, so this is just a teaser. Code Squiggles don’t add functionality or safety to your code, but seek to improve the readability of your code. The ultimate goal is to have your program written down in plain english with a few funny letters in between. Basically, they are intentional bloat to help the casual code reader.

As usual, the topics ranged from first-hand experiences and impressions to literature reviews and research. For additional information provided by the talk authors, check out the comment section (or leave a comment to request further content). Comments and resources might be in german language.

Retrospection of the brunch

Today, we started by giving a quick introduction of ourselves to each other. Being a small group, we digressed a lot more as time wasn’t that much of an issue. The list above is in no way a summary of all the sidenotes and topics we really talked about, it’s just the main topics that served as a starting point for insightful developer chatter. The brunch keeps getting better.


Follow-up to our Dev Brunch May 2010

May 28, 2010

Last sunday, we held our Dev Brunch for May 2010. It was a small group of developers brunching together this time. One reason was a communication failure on my part, as a crucial email announcing a change in the appointment didn’t reach everyone interested in participating. Sorry for this one again! The other reason was more of a pleasure: Two of our regular brunch attendees are turning into parents. But a core group brunched and talked in the office roof garden, discussing the topics listed below.

The Dev Brunch

If you want to know more about the meaning of the term “Dev Brunch” or how we implement it, have a look at the follow-up posting of the brunch in October 2009. We continue to allow presence over topics. Our topics for the brunch were:

  • Options in Scala – If you are used to traditional programming languages like Java, you might be surprised that you can’t nullify a reference in Scala. There is no concept of “null” in Scala, therefore avoiding the so-called billion dollar mistake (you might want to listen to the guy who invented the mistake, too). If you want to use “uncertain” references, you should look into the Option type of Scala, which was the main topic of this talk. With some code examples, this was a decent introduction into the concept.
  • Summary of the Sensor+Test trade fair – This talk was a short report of the recently visited german Sensor+Test measurement fair in Nuremburg. Details may follow on this blog, but the overall summary is that the measurement industry in Germany and neighbours is mostly self-confident and down-to-earth.
  • The Modbus protocol - This talk was a short introduction to the ancient (but still useful) Modbus protocol and the possibilities to access it in Java. There are at least two projects that provide full coverage of the protocol: jamod and modbus4j. The protocol itself is rather low-level, but sufficient for simple control and data query tasks on an embedded device. The possibility to be mostly agnostic over the physical transport layer is a strength of the Modbus protocol and its implementations.
  • Usage patterns for mocks – Most of us had to confess: we are mockists. But there are many different flavors of using mocks in tests. Inspired by the book “Growing Object-Oriented Software, Guided by Tests”, this talk was an open discussion round about personal mock usage preferences.

As usual, the topics ranged from first-hand experiences and impressions to literature reviews and research. For additional information provided by the talk authors, check out the comment section (or leave a comment to request further content). Comments and resources might be in german language.

Retrospection of the brunch

The usual brunch setup is nearly perfect. What was lacking this time was the coordination of the appointment. To further improve on that point, we introduced a new mailing list, containing everone that is currently interested in participating the brunch.


Follow-up to our Dev Brunch April 2010

April 21, 2010

Last sunday, we held our Dev Brunch for April 2010. It was the start of the open air season, introducing our new office roof garden. We brunched under a clear, sunny sky (no clouds, even no vapor trails from airplanes, as they aren’t allowed to fly because of some distant volcano ash emission) and talked about agile processes and books. A major part of the brunch was graded as “informal chatter”, just as it should be like.

The Dev Brunch

If you want to know more about the meaning of the term “Dev Brunch” or how we implement it, have a look at the follow-up posting of the brunch in October 2009. We continue to allow presence over topics. Our topics for the brunch were:

  • Agile life planning – Your software development daily routine is to incrementally build software from a backlog and release it after a fixed timebox. What might happen if you transfer this process to your private life (often called “real life”)? You’ll release a week’s life every week and have a week planning meeting on sunday, filling your week/sprint backlog with the most important items of your life’s backlog. Telling from this first hand experience of about a year, it works exceptionally well, improving the leisure time quality and making “progress” visible even at harder times. The only remaining question is who acts as the product owner.
  • Converting to Scrum – First hand experience of a team that, after years of “alarm call”-style development, successfully implemented Scrum as their primary process. The effects were at least less overtime, improved progress tracking, improved code quality (though Scrum is  only a management process!) and less pressure in the project. The customer even adjusted their wording when talking about new features: “next sprint” instead of “immediately, now”. The implemented process isn’t vanilla Scrum, but works nevertheless.
  • Defending Continuous Integration – What if, after an initial phase of excitement over the new tool, the continuous integration server really reveals flaws in your project? There seems to be the tendency to kill the messenger: Shut down the CI server and everything’s fine again. This talk was about the reasoning of both sides and some basic insights gained about machine sharing. Tip of the talk: Reserve your CI server exclusively for this task.
  • Book recommendations – A random collection of technical books read in the last half year, presented with a short summary and personal rating. Titles included were Coders At Work, Founders At Work, 97 Things Every Software Architect Should Know, 97 Things Every Project Manager Should Know, 97 Things Every Programmer Should Know, Hiring the Best Knowledge Workers, Techies & Nerds and Manage Your Project Portfolio. Yes, there are some patterns visible in the book titles. And it’s a good idea to keep some checklist of read articles for most of these books.
  • Dreyfus Model of Skill Acquisition – The Dreyfus Model differentiates five to six different stages of learning some arbitrary skill. It makes assumptions how the members of the stages work, how they process feedback information and what they need to get better. See the comment section for more information and bonus material.

As usual, the topics ranged from first-hand experiences to literature research. For additional information, check out the comment sections. Comments and resources might be in german language.

Retropection of the brunch

Holding the brunch in the bright morning sun, surrounded by rooftops and birds, really is a huge gain for the ambience factor. We even found a solution to produce fresh coffee up there. This will be a fun summer for the Dev Brunch.
