8U Rolling Rack for Video/Streaming build

 

Started on my 8U Rack build with various components ordered from a magnitude of sources.

Vlog from a few days ago, already outdated:

Current idea goes as follows:

  • Gator 8U Rolling Rack for ease of transportation. It actually is 8U according to pictures, some other 8U rollers are only 7U due the roller parts consuming one U.
  • Black Magic SmartView 4K and Intel NUC VESA mounted behind (probably do something with zip ties or similar to secure the NUC well, so it cannot fall out of VESA-mount)
  • Black Magic Web Presenter for 720p down-scaled streaming with Black Magic Teranex Mini Smart Panel for operating switching etc on the Web Presenter
  • Black Magic MicroConverter HDMI-SDI to enable Intel NUC to be displayed on the SmartView
  • Black Magic MicroConverter HDMI-SDI to enable second HDMI camera.

Geocaching 2016

Geocaching året 2016 blev ett lite mer avslappnat år där Geocachingen inte stod i fokus (desto mer annat), men en del underbara platser sågs. Lite resor i Tyskland-Belgien-Luxemburg och lite lugn geocaching på hemmafronten. En lugn geocachingtur med föräldrarna på julafton var ett trevligt inslag.

Luxemburg är ju aldrig fel att se!

Världen var fin!

Man kunde se konstiga saker i Trier

En groda i tyskland.

Rheinsteig tillhör en del av Tyskland man skall ha sett.

En bro!

Någon sorts lastanordning brevid kanalen i Trier.

Försöker hitta vägen ute i hård skärgårdsterräng.

Många loggremsor sågs.

Och fotades.

XMAS2014-24 Reviewergömman hittades liggandes 40-50 meter ifrån där den skulle vara, mugglad. Så den återförlyttades till där den skall vara.

En Geocache fick inleda januari 2017.

Recording computer presentation Live Capture with Atomos Ninja 2 HDMI to SSD recorder – Lessons Learned

Recording HDMI from Computer

Successes

  • Verified okay with Macbook Pro HDMI port, using normal applications like viewing videos and surfing the internet, no issues.
  • Verified okay in live use with a Microsoft Surface with mini-displayport.

Failures

  • Presenter running virtual machines (parallels or such) on Mac. Whenever switching to the virtual environment, HDMI recording and pass-through freezed. Unplugging Atomos unit and connecting Mac directly to the projector, everything worked well.
  • Presenter with an old and torn Mac experienced some temporary screen glitches. Considering the physical state of the the machine, the fault could have been with the HDMI port of that computer and not the Atomos recorder.
  • Presenter with a Mac experienced a HDMI blackout followed by Powerpoint for Mac hanging. So eh, may or may not have been related to the Atomos. Being paranoid, I decided to continue without the Atomos NINJA 2 connected.
  • Presenter with an exotic variant of Linux could detect the Atomos NINJA 2, but was unable to output signal to it. Perhaps it would have worked with other variants of Linux or with more advanced settings.
  • A low cost Delcato Prime VGA-to-HDMI converter did not seem to work at all together with the Atomos. So with this combination, no VGA recordings succeeded.
  • Multiple presenters who had said they had HDMI actually had full sized Display Port. Presenters are not necessarily aware of which cable is named what.

Retrospective / Lessons learned

  • Atomos Ninja 2 is considerably worse than a normal TV/Receiver/Projector at handling ”strange” signals. Lack of supported resolutions, lack of re-scalers, etc (your guess is as good as mine) makes it not able to handle misbehaving or odd computers. But geeks heavily hacked computers will not work.
  • Atomos Ninja 2 works pretty well for ”normal computers with normal HDMI”.  If all you do is to show presentations on a computer you can test and verify in advance, things will probably be okay.
  • You probably need an advanced and well behaving HDMI switch which can do splitting/rescaling etc to reliably use Atomos NINJA2 with geeks hacked computers. Don’t have the Ninja 2 inline with untested presenter computers.
  • Don’t expect a cheap VGA-to-HDMI device to work with this.
  • Get all passive adapters known to man before a presentation. Presenters don’t necessarily correctly identify their needs when asked.
  • You need a lot more time than we had (partly due to Atomos RMA issue) to prepare.

General issues (not computer related)

  • Atomos NINJA2 number one had a weird banding issues on the screen, that basically rendered it unusable with my main camera, had to be RMA’d. Getting a replacement Atomos NINJA2 took forever. So in my unfortunate experience, you cannot order a Atomos unit one month in advance and expect to have any learning experience with it.
  • Both Atomos NINJA2 have a tendency to get SSD stuck. This is apparently normal with new units and problem is reduced significantly after some use (wear and tear makes it better). Dealer showed me the very useful to know the best grip for easy removal:
    1. place unit on a flat table with screen up, ”NINJA 2” text up-side-down close to you.
    2. Use left hand to hold unit and move the eject button with one finger. At the same time, use your right hand thumb to press the closest edge of the Master Caddy.
    3. The drive should remove pretty easily
  • Getting Master Caddy II instead of the original Master Caddy is recommended, it lacks the hole that makes Master Caddy get stuck.

River of Light

On 20 February 2016, hundred and fifty lanterns will create a ‘River of Light’ for one night event in the city of Gothenburg, in the winter darkness bringing people together to celebrate our hope for the future. We gather at 16.00 at Götaplatsen to light the lanterns. After that we walk trough the city and the procession ends at A-venue on Avenyn at 18.00 with soup and bread and festivities.

The procession is a part of the 150 years celebration of the Valand Academy and on UN World Day of Social Justice which is annually observed on February 20.

During the last couple of months has the refugee crisis become worse and worse and Sweden has taken in on third of all the unaccompanied minors seeking asylum in Sweden. They come to Sweden as it is a country with an excellent reputation for respecting Human Rights and recognized for the good education system. Migrationsverkets numbers shows us that there were 30 000 children without their family in Sweden by the end of 2015. The situation in Gothenburg is also getting worse, with to little room for the young people seeking a safe place to stay.

In the project “River of Lights” and artists from the Academy of Valand has worked with international children, many of them who just arrived from Syria and Afghanistan, and created lanterns together.

Mario Heiderich – An Abusive Relationship with AngularJS – About the Security Adventures with the ”Super-Hero” Framework

Some voices claim that ”Angular is what HTML would have been if it had been designed for building web applications”. While this statement may or may not be true, is certainly accounts as one of the bolder ones a JavaScript web framework can ever issue. And where boldness is glistening like a German Bratwurst sausage in the evening sun, a critical review from a grumpy old security person shouldn’t be too far away. This talk will have a stern, very stern look at AngularJS in particular and shed light on the security aspects of this ever-popular tool. Did the super-hero framework do everything right and follow its own super-heroic principles? Does AngularJS increase or rather decrease the attack surface of a web application? How does AngularJS play along with the Content Security Policy, and was it a good idea to combine this kind of security with futuristic feature creep? And what about AngularJS version 2.0? Beware that we won’t stop at glancing at the code itself, investigating security best practices, and verifying compatibility and other common things that contribute to robust security (or lack thereof). We will cross the moral border and see if the AngularJS team could notice rogue bug tickets. A pivotal question that everyone is wondering about is: Have they successfully kept evil minds like yours truly speaker here from introducing new security bugs into the code base? This talk is a reckoning with a modern JavaScript framework that promises a lot and keeps even more, not necessarily for the best for developers and users. We will conclude in deriving a general lesson learnt and hopefully agree that progress doesn’t invariably mean an enhancement.

An Abusive Relationship with AngularJS – About the Security Adventures with the ”Super-Hero” Framework. Dr. Mario Heiderich, handsome heart-breaker, bon-vivant and (as he loves to call himself) ”security researcher” is from Berlin, likes everything between lesser- and greater-than. He leads the small yet exquisite pen-test company called Cure53 and pesters peaceful attendees on various 5th tier conferences with his hastily assembled PowerPoint-slides and a lot of FUD.

Marie Moe: Unpatchable – Living with a Vulnerable Implanted Device

My life depends on the functioning of a medical device, a pacemaker that generates each and every beat of my heart. This computer inside of me may fail due to hardware and software issues, due to misconfigurations or network-connectivity.

Yes, you read that correctly. The pacemaker has a wireless interface for remote monitoring and I am forced to become a human part of the Internet-of-Things. As a seasoned security-professional I am worried about my heart’s attack surface.

This talk will be focused on the problem that we have these life critical devices with vulnerabilities that can’t easily be patched without performing surgery on patients, my personal experience with being the host of such a device, and how the hacker community can proceed to work with the vendors to secure the devices.
