AWS PopupLoft in München

Habe eine Einladung von Amazon Web Services zur Besichtigung des temporären Pop-up Loft München bekommen, nicht weit vom Hauptbahnhof (Briennerstrasse 49).

Auf drei Ebenen gibt es Vorträge, Schulungen, einen Workspace und Demos.
Im Keller kann man Echo als Sprachsteuerung in Verbindung mit einer Carrerabahn bewundern, sich selbst Cloud-unterstützt ein Legomännchen zusammenbasteln und direkt am Eingang einen Amazon Snowball inspizieren – die Lösung, um große Datenmengen via verschlüsselter Plattensysteme in die Cloud zu befördern statt via Internet zu übertragen.

Fazit: Sehr zu empfehlen, Eintritt/Vorträge sind kostenlos und bieten sich zum Networken an.

2016 Euro Expedition: Pohoda, High Tatras, Ukraine, Romania

The 2016 Euro Expedition followed the following route:
Starting point was Munich, Germany and from there with the Jeep to Vienna, Austria and onwards to Trencin/Pohoda festival for a long weekend. We moved on to High Tatras mountains to climb the beautiful area and north-western peak of Rysy mountain (2499m).

After that I pushed alone to Košice, the easternmost big Slovakian city and from there over the border to Uzhhorod, Ukraine. From there to Ivano-Frankivsk and further to Chernivtsi to visit the famous university.
This was also the last big city in Ukraine, from there I went south to Vornet, Romania to visit the monastery which is quite a touristy place nowadays. The big city I stayed a bit was Cluj-Napoca in the west which is quite a busy place also with a few fine vegan restaurants (go to Samsara).

Next spot was camping in Budapest, Hungary at Arena Camping before the final trip back to Munich.

Equipment-wise this was the first time I used my roof tent. Despite two zipper incidents it was quite good (sleeping comfort, build-up time). Also first for me: crawling around on the roof of the Jeep.

Linzer Torte auf der Gafadura Hütte

Zuerst ging es am Morgen nach Vaduz, um ein wenig die kleine Hauptstadt Liechtensteins zu erkunden. Hopp zur Burg und St. Florin-Kirche, leider zu spät für das Kunstmuseum. Am Abend ging es dann nach Eschen, wo ich mich im B&B Schönblick einquartiert hatte. Um den Tag vollends auszunutzen gings sportlich in einer Stunde durch den Wald hoch zur Gafadura Hütte. Den Ausblick auf das Tal und die umgebenden schneebedeckten Berge konnte ich erst garnicht genießen. Nach Apfelschorle und einem Stück Linzer Torte ging es aber wieder.

Danach lockerer Abstieg zurück zum Jeep und dann nach Eschen. Superglücklich die Tagesziele bei wunderschönem Wetter erreicht: das 50. Land erkundet sowie den Berg hoch gekraxelt, dank Föhnwind noch unter der Schneegrenze.

Concert: Jamie Woon

Went to Technikum on Friday, April 15th, a small event venue at Kultfabrik area besides Ostbahnhof in Munich to see and listen to Jamie Woon. Let’s talk about environment. The lighting was excellent for such a small place and provided a great visual background. For me it’s also important that it’s not crazy hot when the room is stuffed with people – was ok there due to high ceilings and ventilation.

Warmup was provided by Jodie Abacus. The charming singer provided nice music, however the song texts were a bit weird – spoon? Coca-cola? I think I would have liked it much better if I didn’t understand the text. So please, better lyrics would be appreciated.

Main act Jamie Woon provided a great show, especially to mention the two sidekick singers contributed to an excellent atmosphere. One song before the last he did an intense solo with guitar. I think the last song was Shoulda, fitted perfectly.

Jamie Woon: Shoulda

AWS Summit 2016 in Berlin

This year I headed to my first AWS Summit which conveniently located at the event location Station in Berlin.

I started quite early on the morning of April 12th, 2016 at around 8:30.
The waiting queue from the train station to the event location looked a bit frightening but the progress was quite quick. After my personal badge with Name and QR code was printend I entered the venue where many companies had their booths, areas for free food and drinks and of course multiple session areas waited for speakers and listeners.

But first there was the keynote, presented by Werner Vogels himself, CTO and VP of Amazon. Feel free to check out his blog: All Things Distributed.
Important parts were the reasons why a company has to move on with digitalization, the rise of simplification, achievements, new products like lambda and focus on the increasing abilities of the German location in Frankfurt:

  • AWS Device farm: mobile device testing
  • AWS Snowball: 50GB storage package to send via postal service for large data injection to the cloud
  • Book suggestions by Mr. Vogels: The lean Enterprise, Building Microservices, The Phoenix Project

There were also some Guest speaker presentations. The first one was not good compared to the energetic presentation by Vogels. Following were a new spinn-off by ProSiebenSat1, quite nicely presented and AirBerlin which showed the possibility of cost savings in a very competetive market. At last a cool presentation by Berlin startup Dubsmah which already grew around the world.

Some good sessions, some talks with nice startups and companies, for example:

  • number26: speed up banking process without waiting for an appointment
  • RedHat CloudForms: monitoring VMs and Cloud instances together
  • Stylight: move to AWS infrastructure finished
  • Startup presentations: kinetize, staticgen

And of course the very nice after party is to mention, with a performance by Izzy Bizu.

Netgear GS716T v3: update Firmware

After trying to see the Device View which is a Java applet I just got a message by my browser that it is blocked. Checked the firmware version and the installed one 6.3.1.4 is older than 6.3.1.11 available on the netgear homepage.

Easy steps to update
I downloaded 6.3.1.11

Upload (save current image)
I saved the current version (named image1) by navigating to Maintenance > Upload > HTTP File Upload, then File Type = archive and Image Name = image1. After clicking APPLY, you can download the current image of the switch.

Download (write new image)
After that I went to Maintenance > Download > HTTP File Download and put the new .stk filewhich is part of the firmware .zip to the switch.

Activating Image
Now to Maintenance > File Management > Dual Image Configuration to activate image2. I also named it according to the firmware version and clicked APPLY. I double-checked via the menu item Dual Image Status:

Reboot switch
After that I did Maintenance > Reset > Device Reboot. Once the switch was back again after about 2 minutes I checked the used firmware version and it showed the new one. Then I navigated to Device View and – it now works with Java 8. Mission accomplished.

Jinbei Digital Pioneer III 300

Just recieved a new Jinbei Digital Pioneer III 300 to accompany the one I got a couple of years ago in Singapore. Interestingly they look quite a bit different despite the same name. Especially added 2.4GHz Receiver and faster recharge times after flashing are quite nice. Also the buttons look different, now there is a Flash Energy Output Control Knob instead of mere +/- buttons.
Now I have to check if the lights are still comparable (same light temperature, same flash power levels).

Managed Switch: Netgear GS716T v3

To bump up the connection and also avoid sloppy Wifi rates around my flat I went a bit further than just buying a cheap switch and got a 16 port managed switch, the Netgear GS716T-300EUS Smart Managed Switch.
Downside of the cheap Netgear device is that the management software is only available for Microsoft Windows, not for Linux or MacOSX. However, web configuration is possible and everything important should be available via the web interface.

Next I Installed Nagios which was not that easy as the primary hints on how to do it via homebrew were wrong/bad. I found an older instruction which helped me to get there. The switch was now able to tell me via SNMP that the intended ports were up and how long it was turned on so far.
