And of course a lot of regular attendees. With over 70 attendees this is our biggest conference.
For Geoff Perlman this is the first European conference since 2008. Your chance to talk to the CEO of the company and ask all your questions without traveling to the USA. Along with Geoff comes Travis Hill, the developer who is in charge for Android.
From Europe we will have all four local Xojo employees: Stéphane Pinel from France, Ulrich Bogun from Germany, Antonio Rinaldi from Italy and Javier Rodriguez Menéndez from Spain. Your chance to talk to someone from Xojo in French, German, Italian or Spanish.
If you have questions about DynaPDF, be sure to ask Jens Boschulte about his library. The plugin part is from me, so for plugin questions check with me. But if you need new PDF features, ask Jens and once he adds them, I can update the plugin.
Carol and Bob Keeney join us and can show you the BKeeney products like Shorts, FTC and Active Records. With over ten years of consulting experience you can learn from them how to do contracts, handle clients and run a Xojo consulting firm.
You may be a subscriber of the Xojo Developer Magazine. Marc Zeedar, the publisher of the magazine, will attend our conference. Be sure to talk to him about how he automates the production of the issues. If you like to get one of the year books, you can email him to bring you a copy.
For the first time we could get Björn Eiriksson to leave Iceland and join a Xojo conference. Björn creates plugins for Xojo for over 15 years and is great guest to have.
Finally Yousaf Shah will talk about running a business, David Cox about web apps, Mattias Sandström and Heinz Jürgen Groß about their Raspberry Pi projects.
And there is you: Bring your computer with your projects. Show your projects and see what others do. Learn from them how they solved problems and implemented great features. If you found an issue with Xojo, demonstrate it to a Xojo engineer. Sometimes the direct contact helps to identify a bug or add a little feature right away.
I know I have over 20 Xojo developers using my plugins in Phoenix alone. A few more live down in Tucson, so maybe I could make a trip to visit Tucson and meet them.
And a few FileMaker people may not be able to join the conference, but still have time for a casual meeting.
So my offer as usual: I reserve a table in a nice restaurant and be there. You can join and we can shop talk all night. Ask me plugin questions, bring your laptop and show projects.
If you are interested, please add yourself to the survey. And please make sure I know your email address, so I can contact you with details on the location. Suggestions are welcome!
The last weeks I worked on integrating Amazon S3 for a client. Normally using any web services is not much work as our CURL functions in the plugin handle the transfer thing with authentication and encryption. But for Amazon's web services, some extra work is needed.
So for next plugins, I implemented AWS4-HMAC-SHA256 signatures. They are required to authenticate and talk to the web services. To setup this, you pass our plugin the required informations: AWSAccessKeyId, AWSSecretAccessKey, Region, Service, Path, Domain, Verb, HashedPayload, Headers. The key and secret are available from Amazon on their website. The region defines where your server is, for me eu-central-1 with server in Frankfurt, Germany. The service in my case is s3. The path defines the path to the file, e.g. "/test.jpg". The domain can be calculated by plugin or overwritten by you. Usually it is something like s3.eu-central-1.amazonaws.com with various region names included. Verb defines which HTTP operation to do: get, put, delete or post.
The payload sent needs to be included in the signature. So if you provide the data to upload/send before our call to setup with our input functions, the plugin can hash it and include the hash. Or you provide a hash, a lowercase hex encoded SHA256. Especially when uploading a file which does not fit in memory, it may be an option to hash it yourself.
Next you can include various headers. The headers are included in the signature and passed to CURL for the transfer. Our plugin functions add extra headers for amazon and pass the URL to CURL with a few options. You can than add more options like SSL certificates and start the transfer.
The examples will show how to upload/download an image file to Amazon S3 in your bucket.
Coming soon with next plugin update.
PS: if you have older code for Amazon, you may need to update it to use AWS4-HMAC-SHA256, too. Newer regions only support the newer scheme and not the older signature system.
This weekend I participated in the CURL conference in Nuremberg.
It’s great to finally meet the people behind CURL and learn bow all came together and what direction they want to go. We had over a dozen interesting presentations and I learnt a lot about HTTP/2, SSL security and how people use CURL in various ways.
One of the things I learnt from a nice fellow is how to load the system certificates on Windows. I even found similar code for macOS, so next plugins can use system certificates.
So we have now 4 ways to handle SSL security:
Ignore it and accept all certificates. OptionVerifyPeer = 0 and OptionVerifyHost = 0 No verification is done and middle man attack is very easy.
Use a cacert.pem file with root certificates and verify against those. Use this for certificate pinning. Put the certificates of your servers in a pem file and only allow those. Or get a general cacert.pem file with common root certificates.
Use system provided SSL functionality, see CURLNMBS class. Only for Mac and Windows in our Xojo plugins.
New: Load system certificates and verify against them. For Mac and Windows with next plugin version.
Please try them soon in FileMaker and Xojo and let me know if they work fine for you.
I even thought about using the system certificates by default if you don’t provide certificates, but ask to verify.
The conference was great and thanks to everyone helping. See you again some day!
NICKENICH, Germany (March 14th, 2017) -- Monkeybread Software releases version 17.1 of the MBS plug-in for Xojo and Real Studio.
The MBS plug-in comprises a collection of several plug-in parts which extend the Xojo (Real Studio) development environment with 2,400 classes featuring over 62,000 documented functions. Our plugins support all three platforms Mac OS X, Windows and Linux with all project types desktop, web and console including 64-bit and ARM targets.
Some of the highlights on the 17.1 update:
The new NSOutlineControlMBS and the improved NSTableControlMBS controls allow you to implement modern table controls based on Apple's Cocoa controls. Included with the plugins are example projects to show how to replace the standard listbox with our replacements.
For CURL we now have three variants: CURLS classes come with an internal CURL, SSL and SSH library, so you can use it without installation extra libraries. For Mac and Windows the CURLN classes allow you to use native SSL. And the CURL classes without N or S allow you to use your own library files. Our examples mostly demonstrate using CURLS to show you the same behavior cross platform.
Our new ParseDateMBS function parses date and time. You specify the format of the date to parse. Same format can be used with FormatDateMBS function to format a date or time in as specific format.
The functions to edit word files can now extend tables. If your template contains a table and you want to flexible add rows and fill them, you can now duplicate a row as needed and insert it below or on the end of the table.
For Windows we implemented a new class WindowsProcessMBS as a native shell class replacement. You can launch processes and receive their output as string as well as send input to them. Optionally you can use cmd.exe to run shell commands.
You can use the WinNotificationMBS class to draw into a MDI parent window of your application. Our example shows how to draw a picture there. This class is mostly used to be notified about global events like screen resolution changes.
We updated the controls in the plugin and added new mouse events. The cocoa controls got FrameChanged and BoundsChanged events to recognize size changes.
Finally we updated PortMidi, Tidy to version 5.3.15, DynaPDF to 220.127.116.11, SQLite to 3.17.0 and CURL to 7.53.1.
On my next visit to Nuremberg, I'd love to make another FileMaker and Xojo developer meeting:
Wer hat Interesse an einem Xojo und FileMaker Entwicklertreffen am 17. März 2017 in Nürnberg?
Einfach gemütlich zusammen sitzen und über Xojo und FileMaker plaudern.
Gerne zeige ich auch neue Pluginfunktionen oder helfe bei Problemen mit euren Projekten. Einfach Computer mitbringen und was zeigen.
