  • Mit Oracle Datenbanken in die Pole-Position!

    - by Alliances & Channels Redaktion
    Stellen Sie sich vor, Sie haben die Wahl zwischen einem hübschen, aber uralten Kleinwagen und einem stylischen Tourenwagen auf technischem Höchststand. Beide haben etwas für sich, keine Frage, doch auf der Rennstrecke, wo es allein um Performance geht, ist Nostalgie fehl am Platz. Nicht anders ist es mit Datenbanken. Wer also Wert auf Leistung, Sicherheit und die optimale Ausnutzung von Hardware und IT-Ressourcen legt, sollte sich für ein Database-Tuning entscheiden. Die wesentlichen Vorteile der Oracle Datenbanken bringt dieses Video kurz und knackig auf den Punkt – und ist damit auch bestens zum Einsatz bei Kunden geeignet.

  • MySQL: select words as rows even som are "new line" separated in one field

    - by Tillebeck
    Hi I have a table with a field where words are written separated with new lines. So a select on this single field from to rows will output 3 lines for first row and 2 lines for second row: Row1 designationer nye kolonier mindre byer Row2 udsteder bopladser I would like to do a select that select all these lines as if they had been rows in the table like: SELECT do_the_split(field) FROM table so the result would be more like: Row1 designationer Row2 nye kolonier Row3 mindre byer Row4 udsteder Row5 bopladser is there any way to do this in MySQL?

  • PHP Form: After getting results adding a new table row when entering new information.

    - by Chris
    Hello, Although probarly quite simple, i cannot seem to find the following. The form takes certain data, and then represents the data in a table. Next step i click the hyperlink that takes me back to the form. Now my question is how exactly do i make it possible when filling in the same form again so both results are displayed in the same table? Then filling in a other form with data adds another row and so on. Regards. The code below (pardon me that it is not english). <?php session_start(); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-Strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>ExpoFormulier</title> <body> <?php if (!empty($_POST)) { $standnaam = $_POST["standnaam"]; $oppervlakte = $_POST["oppervlakte"]; //value in the form van checkboxes op 1 zetten! $verdieping = isset($_POST["verdieping"]) ? $_POST["verdieping"] : 0; //if checkbox checked value 1 anders 0 $telefoon = isset($_POST["telefoon"]) ? $_POST["telefoon"] : 0; $netwerk = isset($_POST["netwerk"]) ? $_POST["netwerk"] : 0; if (is_numeric($oppervlakte)) { $_SESSION["standnaam"]=$standnaam; $_SESSION["oppervlakte"]=$oppervlakte; $_SESSION["verdieping"]=$verdieping; $_SESSION["telefoon"]=$telefoon; $_SESSION["netwerk"]=$netwerk; header("Location:ExpoOverzicht.php"); //verzenden naar ExpoOverzicht.php dmv header } else { echo "<h1>Foute gegevens, Opnieuw invullen a.u.b</h1>"; } } ?> <form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" id="form1"> <h1>Vul de gegevens in</h1> <table> <tr> <td>Standnaam:</td> <td><input type="text" name="standnaam" size="18"/></td> </tr> <tr> <td>Oppervlakte (in m^2):</td> <td><input type="text" name="oppervlakte" size="6"/></td> </tr> <tr> <td>Verdieping:</td> <td><input type="checkbox" name="verdieping" value="1"/></td> <!--value op 1 zetten voor checkbox! indien checked is value 1 --> </tr> <tr> <td>Telefoon:</td> <td><input type="checkbox" name="telefoon" value="1"/></td> </tr> <tr> <td>Netwerk:</td> <td><input type="checkbox" name="netwerk" value="1"/></td> </tr> <tr> <td><input type="submit" name="verzenden" value="Verzenden"/></td> </tr> </table> </form> Second File: <?php session_start(); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-Strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>ExpoOverzicht</title> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <link href="StyleSheetExpo.css" rel="stylesheet" type="text/css" /> </head> <body> <h1>Overzicht van de ingegeven standen in deze sessie</h1> <?php $standnaam = $_SESSION["standnaam"]; $oppervlakte = $_SESSION["oppervlakte"]; $verdieping = $_SESSION["verdieping"]; $telefoon = $_SESSION["telefoon"]; $netwerk = $_SESSION["netwerk"]; $result1 = 0; //telkens declaren anders fout "undefined variable" $result2 = 0; $result3 = 0; $prijsCom = 0; $prijsVerdieping = 0; for ($i=1; $i <= $oppervlakte; $i++) { if($i <= 10) { $tarief1 = 1 * 100; $result1 += $tarief1; } if($i > 10 && $i <= 30) { $tarief2 = 1 * 90; $result2 += $tarief2; } if($i > 30) { $tarief3 = 1 * 80; $result3 += $tarief3; } } $prijsOpp = $result1 + $result2 + $result3; if($verdieping == 1) { $prijsVerdieping = $oppervlakte * 120; } if(($telefoon == 1) || ($netwerk == 1)) // eerst deze OR conditie of anders gebruikt de code alleen nog maar 20 { $prijsCom = 20; } if(($telefoon == 1) && ($netwerk == 1)) { $prijsCom = 30; } $totalePrijs = $prijsOpp + $prijsVerdieping + $prijsCom; echo "<table class=\"tableExpo\">"; echo "<th>Standnaam</th>"; echo "<th>Oppervlakte</th>"; echo "<th>Verdieping</th>"; echo "<th>Telefoon</th>"; echo "<th>Netwerk</th>"; echo "<th>Totale prijs</th>"; echo "<tr>"; echo "<td>".$standnaam."</td>"; echo "<td>".$oppervlakte."</td>"; echo "<td>".$verdieping."</td>"; echo "<td>".$telefoon."</td>"; echo "<td>".$netwerk."</td>"; echo "<td>".$totalePrijs."</td>"; echo "</tr>"; echo "</table>"; ?> <a href="ExpoFormulier.php">Terug naar het formulier</a> </body> </html> </body> </html>

  • Adding nodes to drupal from remote site using ajax and post

    - by andersandersson666
    I'm trying to add nodes to my drupal site, from a campaignsite using AJAX request. I have set up a menu_callback item in my hook_menu, that checks if any $_POSTs are coming in, and it works if i make a form that has the action='http://mysite.com/menucallback/url', but i get nothing in response if i make the same request with ajax. I have access arguments set to 'access content'. If anyone knows what might be the problem, that would be very helpful. Thank you. /Anders

  • DevDays ‘00 The Netherlands day #1

    - by erwin21
    First day of DevDays 2010, I was looking forward to DevDays to see all the new things like VS2010, .NET4.0, MVC2. The lineup for this year is again better than the year before, there are 100+ session of all kind of topics like Cloud, Database, Mobile, SharePoint, User experience, Visual Studio, Web. The first session of the day was a keynote by Anders Hejlsberg he talked about the history and future of programming languages. He gave his view about trends and influences in programming languages today and in the future. The second talk that i followed was from the famous Scott Hanselman, he talked about the basics of ASP.NET MVC 2, although it was a 300 level session, it was more like a level 100 session, but it was mentioned by Scott at the beginning. Although it was interesting to see all the basic things about MVC like the controllers, actions, routes, views, models etc. After the lunch the third talk for me was about moving ASP.NET webform applications to MVC from Fritz Onion. In this session he changed an example webform application part by part to a MVC application. He gave some interesting tips and tricks and showed how to solve some issues that occur while converting. Next and the fourth talk was about the difference between LINQ to SQL and  the ADO.NET  Entity Framework from Kurt Claeys. He gave a good understanding about this two options, the demos where in LINQ to SQL and the Entity Framework, the goal was to get a good understanding when and where to use both options. The last talk about this day was also from Scott Hanselman, he goes deeper into the features of ASP.NET MVC 2 and gave some interesting tips, the ninja black belt tips. He gave some tips about the tooling, the new MVC 2 html helper methods, other view engines (like NHaml, spark),T4 templating. With this tips we can be more productive and create web applications better and faster. It was a long and interesting day, I am looking forward to day #2.

  • Speaker at the German Visual FoxPro Developer Conference 2005

    The following is an excerpt from the UniversalThread conference coverage of the German Visual FoxPro Developer Conference 2005 written by Armin Neudert and Jan Vit. Unfortunately, my sessions were not covered at all but I was there as a speaker after all: [...] We are happy to welcome back several speakers that have already been giving sessions in previous DevCons, but hadn’t been here for one or more years. In detail: Steven Black is back after several years. Marcia Akins and her husband Andy Kramek couldn’t come in 2004 and are back again now. Regarding German speakers, Andreas Flohr and Torsten Weggen are also here again, after not doing sessions for two, respectively four years at this conference. At this point we would like to send some regards to the speakers that couldn’t come to Frankfurt this year, since they are very busy at the moment or are doing sessions anywhere else in the world right now. We are also proud to announce several speakers that are here for the very first time. Welcome to Doug Hennig, Rick Schumer, Craig Berntson, Marcus Luz and Benjamin Anders. And of course, there all the well known speakers which did great sessions over the last years: Sebastian Flucke, Uwe Habermann, Peter Herzog, Venelina Jordanova, Dan Jurden, Jochen Kirstätter, Nathalie Mengel, Lisa Slater Nichols, Michael Niethammer, Rick Strahl, Markus Winhard, Eugen Wirsing, Christof Wollenhaupt and myself - Armin Neudert :-) [...]

  • Oracle Key Vault - Hardware Security Modul für TDE und mehr

    - by Heinz-Wilhelm Fabry (DBA Community)
    Anfang August hat Oracle ein neues Produkt namens Oracle Key Vault (OKV) zum Einsatz freigegeben. Es handelt sich dabei um ein Hardware Security Modul (HSM) - also um ein Stück Hardware zum Speichern von Schlüsseln, Passwörtern und Dateien, die Schlüssel und Passwörter enthalten. Oracle Datenbank Installationen nutzen die zuletzt genannte Form des Speicherns von Passwörtern und Schlüsseln in Dateien für Oracle Advanced Security Transparent Data Encryption (TDE) und external password stores. Die Dateien werden in den Versionen 10 und 11 der Datenbank als Wallets bezeichnet, in der Version 12 als Keystores. Allerdings gibt es auch schon seit der Datenbankversion 11.2 beim Einsatz von TDE die Möglichkeit, statt der Wallets / Keystores HSMs einzusetzen. Da Oracle selbst kein eigenes HSM Produkt anbieten konnte, haben Unternehmenskunden dann auf Produkte anderer Anbieter zurückgegriffen. Das kann sich mit OKV nun ändern. Abhängig vom Bedrohungsszenario kann die Entscheidung gegen den Einsatz von Wallets / Keystores und für den Einsatz eines HSMs durchaus sinnvoll sein, denn ein HSM bietet mehr Sicherheit: Eine Betriebssystemdatei kann leichter gestohlen (kopiert) werden, als ein HSM, das in der Regel als speziell gesicherte Steckkarte in einem Rechner eingebaut ist oder als eigenes Gerät geschützt in einem Rechenzentrum steht. ein HSM kann anders als ein Wallet / Keystore systemübergreifend verwendet werden. Das erlaubt eine gemeinsame Nutzung von Schlüsseln - was wiederum zum Beispiel den Einsatz von TDE auf RAC Installationen perfekt unterstützt. ein HSM kann von mehreren Anwendungen genutzt werden. Das erleichtert das Konsolidieren und Verwalten von Passwörtern und Schlüsseln. Im aktuellen Tipp wird als Einführung in das neue Produkt dargestellt, wie OKV für TDE genutzt werden kann.

    - by Bob Rhubart
    Oracle's Analytics, Engineered Systems, and Big Data Strategy | Mark Rittman Part 1 of 3 in Oracle ACE Director Mark Rittman's series on Oracle Exalytics, Oracle R Enterprise and Endeca. Series: How to Kill the Architecture Department? Part 1 | Xebia Blog Don't let the title fool you. This is not an anti-architecture post. Rather, this post, part 1 of a now four-part series, offers suggestions for preserving architecture in a form that better supports agile organizations. BPM Suite configure BAM Adapter | Peter Paul van der Beek "To have the BPM server push events to BAM – Business Activity Monitoring – we have to configure the BPM suite to use the BAM Adapter," says Peter Paul van de Beek. "The BAM Adapter is configured (like other SOA Suite and BPM Adapters) in the WebLogic Server Console." Peter Paul shows you how in this brief post. A case for not installing your own software | James Gentsch "I look selfishly forward to cloud computing and engineered systems dramatically reducing the occurrence of problems triggered by unforeseen environmental situations in the software I am responsible for," says James Gentsch. "I think this is an evolutionary game changer that will be a huge benefit to the reliability and consistent performance of the software for my customers, and may make 'well, it works here' a well forgotten phase for future software developers." Thought for the Day "I'm a strong believer in being minimalistic. Unless you actually are going to solve the general problem, don't try and put in place a framework for solving a specific one, because you don't know what that framework should look like." — Anders Hejlsberg Source: SoftwareQuotes.com`

  • Daten versionieren mit Oracle Database Workspace Manager

    - by Heinz-Wilhelm Fabry (DBA Community)
    Wie können extrem lange Transaktionen durchgeführt werden, also Transaktionen, die Datensätze über Stunden oder Tage exklusiv sperren, ohne dass diese langen Transaktionen 'normale' Transaktionen auf diesen Datensätzen behindern? Solche langen Transakionen sind zum Beispiel im Spatial Umfeld keine Seltenheit. Wie können unterschiedliche historische Zustände von Produktionsdaten online zeitlich unbegrenzt vorgehalten werden? Die UNDO Daten, die das gesamte Änderungsvolumen einer Datenbank vorhalten, gewährleisten in der Regel nur einen zeitlich sehr limitierten Zugriff auf 'ältere' Daten. Und die Technologie der database archives, auch bekannt unter dem Namen Total Recall, erlaubt einerseits keine Änderungen an den älteren Daten und steht andererseits ausschließlich in der Enterprise Edition der Datenbank zur Verfügung. Wie kann man die aktuellsten Produktionsdaten für WHAT-IF-Analysen verändern und währenddessen andere Benutzer ungestört auf den Originaldaten weiterarbeiten lassen? Ein SET TRANSACTION READ ONLY erlaubt keinerlei Änderungen und ist ebenfalls begrenzt auf die 'Reichweite' der UNDO Informationen. Zwar könnte man für derartige Analysen eine Datenbankkopie aus dem Backup aufbauen oder eine Standby Lösung implementieren, aber das ist doch eher aufwändig. Es gibt eine verblüffend einfache Antwort auf diese scheinbar komplizierten Fragen. Sie heisst Oracle Database Workspace Manager oder kurz Workspace Manager (WM). Der WM ist ein Feature der Datenbank seit Oracle9i, das sowohl in der Standard als auch in der Enterprise Edition zur Verfügung steht. Anders als in den ersten Versionen ist er längst auch Bestandteil jeder Installation. Um so erstaunlicher ist es, dass so wenige Kunden ihn kennen. Dieser Tipp soll dazu beitragen, das zu ändern.

  • Python repl in python application

    - by Olorin
    Hello i am learning python(so i can use qt with python not only c++) and i'm curios if it would be possible to embed a python interpreter in my application as a repl. I would like to give users to possibility to script the app using python either loading a file (and that file to act as a plugin for the app) or by evaluating code entered in a text box or something like that. Just like you can embed the interpreter in C or C++ and script the app using python can this be done if the application is itself written in python(and made a stand-alone binary using py2exe or something similar)? something like Anders did with the C# repl or Miguel with mono. Thanks.

  • Most wanted feature for C# 4.0 ?

    - by Romain Verdier
    Some blogs on the Internet give us several clues of what C# 4.0 would be made of. I would like to know what do you really want to see in C# 4.0. Here are some related articles: C# 4 tag on Jon Skeet's blog 4 features for C# 4 What do you want in C# 4 Future Focus - I: Dynamic Lookup .NET 4, C# 4 and the DLR Channel 9 also hosts a very interesting video where Anders Hejlsberg and the C# 4.0 design team talk about the upcoming version of the language. I'm particularly excited about dynamic lookup and AST. I hope we would be able to leverage - at some level - the underlying DLR mechanisms from C#-the-static-language. What about you ?

    Hi I have done a bit of searching for a solution to wrap text around an image and came across the JQSlickWrap. http://stackoverflow.com/questions/2457266/jquery-plugin-to-wrap-text-around-images-support-ie6 But it is not working in IE.

  • Please list here your deliberate practices in software development...

    - by JDelage
    What are your deliberate practices in relation with your work as a software developer / professional, or as a CS student? Deliberate practice are exercise and repetitions targeted specifically at an individual's weak points and meant to consistently stretch / grow someone's ability. It was described in this Anders Ericsson paper. To qualify as a deliberate practice, the exercise must satisfy the following: Is not inherently enjoyable. Is not play or paid practice. Is relevant to the skill being developed. Is not simply watching the skill being performed. Requires effort and attention from the learner. Often involves activities selected by a coach or teacher to facilitate learning. Please answer with one practice per answer. I'll seed the question with one possible answer.

  • Getting data from sharepoint into drupal

    - by andersandersson666
    The problem: I am about to develop a Drupal site for a company that stores a lot of data in a sharepoint environment (products, recipes etc...). I need to get that information into my Drupal system somehow. Preferably saving it as drupal nodes. That information will also be edited/added in the sharepoint system, so on top of just saving the data to drupal it will also have to check for updates on a regular basis. One idea for a solution is using some sort of web-service to retrieve data, but i have no idea of how that would be done in drupal. So my question(s) is: Has anyone done anything like this, if so how, or does anyone have any suggestions to how one would go about doing this? Any answers would be highly appreciated. /Anders

As a matter of fact, Windows consistently ranks as the #1 development platform in our surveys, and now also ranks higher than any Linux distribution as a deployment platform among MySQL Community Edition users.   We've made various technical resources available in our MySQL on Windows Resource Center including articles, whitepapers and archived webinars. MySQL users are also sharing their experiences and writing how-to articles, and it's great to see former MySQL/Sun/Oracle employees still contributing! Thanks Anders for a recent step-by-step part 1 article on working with MySQL on Windows.   We also got feedback from customers wishing to get higher-level information about MySQL on Windows, to help them and others in their organizations better understand:   ·       Why is the world's most popular open source database so popular on Windows?   ·       What are the applications for which one should consider MySQL on Microsoft's platform?   ·       How should Windows shops relying on Microsoft databases get going with MySQL?   Those are the questions we aim to answer in our guide "MySQL on Windows - Why, Where and How", that you can download here.

  • How do I fix libdispatch problem crashing Mac OS X apps?

    - by david-ocallaghan
    In the last day I have started having a lot of brokenness on my Mac (MacBook Air running Mac OS X 10.6.2 with all software updates). Most noticably, iTunes no longer syncs with my iPhone. It fails with a crash dialog reporting "AppleMobileDeviceHelper quit unexpectedly" and an error dialog "iTunes was unable to load dataclass information from SyncServices. Reconnect or try again later." I've attempted the fix at support.apple.com/kb/HT1747 but it failed. I've also been having problems (at first seemingly unrelated) with the horrible Cisco VPN client, which started giving me this error: Error 51: Unable to communicate with the VPN subsystem I followed the steps at www.anders.com/cms/192/CiscoVPN/Error.51:.Unable.to.communicate.with.the.VPN.subsystem which don't seem to work for me, although I can connect if I use the command line with sudo : sudo vpnclient connect MyProfile I had a look in the Console app at the diagnostic messages and I noticed a pattern, that a number of apps were reporting "BUG IN CLIENT OF LIBDISPATCH". The affected programs are: AppleMobileBackup AppleMobileDeviceHelper Safari Webpage Preview Fetcher cvpnd (the Cisco VPN daemon) Of these, only the last is non-Apple software! The common text in the diagnostic messages is: Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 1 Dispatch queue: com.apple.libdispatch-manager Application Specific Information: BUG IN CLIENT OF LIBDISPATCH: Do not close random Unix descriptors I'm beginning to wonder if there's a permissions problem, or corruption of an important library, ... I should note that I've rebooted several times and verified the disk permissions and the disk. Any help would be great!

  • attach / detach mssql 2008 sql server manager [SOLVED]

    - by Tillebeck
    An external consult wrote a guide on how to copy a database. Step two was detach the database using Sql Server Manager. After the detach the database was not visible in the SQL Server Manager... Not much to do but write a mail to the service provider asking to have the database attached again. The service porviders answer: Not posisble to attach again since the SQL Server security has been violated". Rolling back to last backup is not the option I want to use. Can any one give feedback if this seems logic and reasonable to assume that a detached database in a SQL Server 2008 accessed through SQL Server Manager cannot be reattached. It was done by rightclicking the database and choosing detach. -- update -- Based on the comments below I update the question with the server setup. There are two dedicated servers: srv1: Web server with remote desktop and an Sql Server Manager srv2: Sql server that can be accessed through the Sql Server Manager on the web server -- update2 -- After a restart of the server the DBA could suddenly do the attachment of the database. And I guess that after the restart it was a simple task. So all of your answer were rigth! It seems that I can only mark one as a correct answer so I marked the first answer correct. But all are correct answer. Thanks a lot. Without posting the link to this thread then we might had so suffer while watching our database beeing restored by a backup :-) Thanks a lot. BR. Anders

  • CascadingDropDown jQuery Plugin for ASP.NET MVC

    - by rajbk
    CascadingDropDown is a jQuery plugin that can be used by a select list to get automatic population using AJAX. A sample ASP.NET MVC project is attached at the bottom of this post.   Usage The code below shows two select lists : <select id="customerID" name="customerID"> <option value="ALFKI">Maria Anders</option> <option value="ANATR">Ana Trujillo</option> <option value="ANTON">Antonio Moreno</option> </select>   <select id="orderID" name="orderID"> </select> When a customer is selected in the first select list, the second list will auto populate itself with the following code: $("#orderID").CascadingDropDown("#customerID", '/Sales/AsyncOrders'); Internally, an AJAX post is made to ‘/Sales/AsyncOrders’ with the post body containing  customerID=[selectedCustomerID]. This executes the action AsyncOrders on the SalesController with signature AsyncOrders(string customerID).  The AsyncOrders method returns JSON which is then used to populate the select list. The JSON format expected is shown below : [{ "Text": "John", "Value": "10326" }, { "Text": "Jane", "Value": "10801" }] Details $(targetID).CascadingDropDown(sourceID, url, settings) targetID The ID of the select list that will auto populate.  sourceID The ID of the select list, which, on change, causes the targetID to auto populate. url The url to post to Options promptText Text for the first item in the select list Default : -- Select -- loadingText Optional text to display in the select list while it is being loaded. Default : Loading.. errorText Optional text to display if an error occurs while populating the list Default: Error loading data. postData Data you want posted to the url in place of the default Example : { postData : { customerID : $(‘#custID’), orderID : $(‘#orderID’) }} will cause customerID=ALFKI&orderID=2343 to be sent as the POST body. Default: A text string obtained by calling serialize on the sourceID onLoading (event) Raised before the list is populated. onLoaded (event) Raised after the list is populated, The code below shows how to “animate” the  select list after load. Example using custom options: $("#orderID").CascadingDropDown("#customerID", '/Sales/AsyncOrders', { promptText: '-- Pick an Order--', onLoading: function () { $(this).css("background-color", "#ff3"); }, onLoaded: function () { $(this).animate({ backgroundColor: '#ffffff' }, 300); } }); To return JSON from our action method, we use the Json ActionResult passing in an IEnumerable<SelectListItem>. public ActionResult AsyncOrders(string customerID) { var orders = repository.GetOrders(customerID).ToList().Select(a => new SelectListItem() { Text = a.OrderDate.HasValue ? a.OrderDate.Value.ToString("MM/dd/yyyy") : "[ No Date ]", Value = a.OrderID.ToString(), }); return Json(orders); } Sample Project using VS 2010 RTM NorthwindCascading.zip

  • Fünf Jahre Bonn-to-Code.Net – das muss gefeiert werden!

    - by WeigeltRo
    Als ich am 1. Januar 2006 die .NET User Group “Bonn-to-Code.Net” gründete (den genialen Namen ließ sich mein Kollege Jens Schaller in Anlehnung an das Motto meines Blogs einfallen), ahnte ich nicht, wie schnell sich alles entwickeln würde. So konnte, nach ein wenig Werbung über diverse Kanäle, bereits am 14. Februar 2006 das erste Treffen stattfinden und wenige Tage später wurde Bonn-to-Code.Net offiziell in den Kreis der INETA User Groups aufgenommen. Das ist nun etwas über fünf Jahre her und soll am 22. März 2011 um 19:00 (Einlass ab 18:30) gebührend gefeiert werden, und zwar im Rahmen unseres März-Treffens. Der Abend bietet Vorträge zu “Flow Design und seine Umsetzung mit Event Based Components” sowie “WCF Services mal anders” (ausführlichere Infos zu den Vortragsinhalten gibt es hier). Anschließend gibt es bei einer großen Verlosung neben Büchern auch hochkarätige Software-Preise zu gewinnen. Zusätzlich zu Lizenzen für JetBrains ReSharper und Telerik Ultimate Collection warten dieses Mal (mit freundlicher Unterstützung durch Microsoft Deutschland) je ein Windows 7 Ultimate und ein Office 2010 Professional Plus auf ihre glücklichen Gewinner. Und wer nicht zu spät kommt, kann auch ganz ohne Losglück eines von vielen kleinen Goodies abgreifen. Eine Anmeldung ist nicht erforderlich, eine Anfahrtsbeschreibung gibt es auf der Bonn-to-Code.Net Website. Es freut mich dabei besonders, dass wir zu diesem Termin u.a. einen Sprecher an Bord haben, der bereits beim Gründungstreffen dabei war: Stefan Lieser. Mittlerweile z.B. durch die Clean Code Developer Initiative bekannt, ist Stefan nur ein Beispiel für eine ganze Reihe von Sprechern auf den diversen Entwicklerkonferenzen, die ihre ersten Erfahrungen u.a. bei Bonn-to-Code.Net gemacht haben. …und was ist in den fünf Jahren so passiert? Einiges! Ein Community Launch Event in 2007, zwei Microsoft TechTalks (2007,2008), Gastsprecher aus ganz Deutschland und dem Ausland (JP Boodhoo, Harry Pierson). Doch nichts hat die fünf Jahre so geprägt wie die Zusammenarbeit mit “den Nachbarn aus Köln”. Zum Zeitpunkt der Gründung von Bonn-to-Code.Net gab es im gesamten Köln/Bonner Raum keine .NET User Group. Und so war es nicht ungewöhnlich, dass der erste Interessent, der sich auf meinen Blog-Eintrag vom 4. Januar 2006 hin meldete, aus Köln stammte: Albert Weinert. Kurze Zeit nach der Bonner Gruppe wurde dann – initiiert durch Angelika Wöpking und Stefan Lange – schließlich die .NET User Group Köln gegründet. Wobei Stefan wiederum vor dem Kölner Gründungstreffen Ende April bereits Bonner Treffen besucht hatte; insgesamt also eine Menge personeller Überlapp zwischen Köln und Bonn. Als nach einem etwas holprigen Start der Kölner Gruppe schließlich Albert und Stefan die Leitung übernahmen, war klar dass Köln und Bonn in vielerlei Hinsicht eng zusammenarbeiten würden. Sei es durch die Koordination von Themen und Terminen oder auch durch Werbung für die Treffen der jeweils anderen Gruppe. Der nächste Schritt kam dann mit der Beteiligung der Kölner und Bonner Gruppen an der Organisation des “AfterLaunch” im April 2008. Der große Erfolg dieser Veranstaltung war der Ansporn, in Bezug auf die Zusammenarbeit ein neues Kapitel aufzuschlagen.
