“Cloud native” is a term used to describe applications designed specifically to run on a cloud-
based infrastructure. Typically, cloud-native applications are developed as loosely coupled
microservices running in containers managed by platforms. These applications anticipate
failure, and they run and scale reliably even when their underlying infrastructure is experiencing outages.
To offer such capabilities, cloud-native platforms impose a set of contracts and
constraints on the applications running on them. These contracts ensure that the applications
conform to certain constraints and allow the platforms to automate the management of the
containerized applications. Many organizations understand the necessity and importance of
becoming cloud native, but do not know where to start. Ensuring that cloud-native platforms
and the containerized applications that run on them work seamlessly together provides the
ability to anticipate failure and the reliability to run and scale even when the underlying
infrastructure experiences outages. This whitepaper describes a number of principles that
containerized applications must comply with in order to become good cloud-native citizens.
Adhering to these principles will help ensure that your applications are suitable for
automation in cloud-native platforms such as Kubernetes.
The VL53L1X is a state-of-the-art, Time-of-Flight (ToF), laser-ranging sensor, enhancing the ST FlightSense™ product family. It is the fastest miniature ToF sensor on the market with accurate ranging up to 4 m and fast ranging frequency up to 50 Hz
Housed in a miniature and reflowable package, it integrates a SPAD receiving array, a 940 nm invisible Class1 laser emitter, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options.
Unlike conventional IR sensors, the VL53L1X uses ST’s latest generation ToF technology which allows absolute distance measurement whatever the target color and reflectance.
It is also possible to program the size of the ROI on the receiving array, allowing the sensor FoV to be reduced.
An experimental extension to Ansible is included that implements host connections over Mitogen, replacing embedded shell invocations with pure-Python equivalents invoked via highly efficient remote procedure calls tunnelled over SSH. No changes are required to the target hosts.
The extension isn’t nearly in a generally dependable state yet, however it already works well enough for testing against real-world playbooks. Bug reports in this area are very welcome – Ansible is a huge beast, and only significant testing will prove the extension’s soundness.
Der ultimative Kick, das außergewöhnliche Geschenk, oder die sinnvolle Lehrstunde. Sie haben die Möglichkeit auf dem Soziussitz eines 200 PS starken Supersportlers Platz zu nehmen und die Rennstrecke vorher auszuwählen.
Wir fahren auf einer BMW S 1000 RR der Fa. Motorrad Faßbender/Krefeld. Ein Liter Hubraum und rund 200 PS beschleunigen Sie von 0-100 Km/h in ca. 2,9 Sekunden, das ist Formel-1-Niveau.

Office 365 Advanced Threat Protection (Office 365 ATP) blocked many notable zero-day exploits in 2017. In our analysis, one activity group stood out: NEODYMIUM. This threat actor is remarkable for two reasons:
Its access to sophisticated zero-day exploits for Microsoft and Adobe software
Its use of an advanced piece of government-grade surveillance spyware FinFisher, also known as FinSpy and detected by Microsoft security products as WingbirdFinFisher is such a complex piece of malware that, like other researchers, we had to devise special methods to crack it. We needed to do this to understand the techniques FinFisher uses to compromise and persist on a machine, and to validate the effectiveness of Office 365 ATP detonation sandbox, Windows Defender Advanced Threat Protection (Windows Defender ATP) generic detections, and other Microsoft security solutions.
While I was searching for a VCS capable RANCID, somewhere under a stone I found Oxidized, a 'silly attempt at rancid'. Looking at it, it seems more sophisticated, so I thought this might be the right attempt. Unfortunately there is no Debian package available, but I found an ITP created by Jonas.
The Tooz project aims at centralizing the most common distributed primitives like group membership protocol, lock service and leader election by providing a coordination API helping developers to build distributed applications.
Tvheadend is a TV streaming server and recorder for Linux, FreeBSD and Android supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, ISDB-T, IPTV, SAT>IP and HDHomeRun as input sources.
Tvheadend offers the HTTP (VLC, MPlayer), HTSP (Kodi, Movian) and SAT>IP streaming.
Multiple EPG sources are supported (over-the-air DVB and ATSC including OpenTV DVB extensions, XMLTV, PyXML).
The Analog video (V4L) is supported directly up to version 3.4.
In recent version, the pipe:// source (in IPTV network) might be used to obtain the MPEG-TS stream generated by ffmpeg/libav from a V4L device.

STMicroelectronics VL53L0X Time-of-Flight Ranging Sensor is a new generation of laser-ranging modules that is housed in one of the smallest packages on the market. The VL53LOX is a fully integrated sensor with an embedded infrared, eye-safe laser, advanced filters and ultra-fast photon detection array. The VL53L0X enhances the ST FlightSense™ family and opens the door for new applications with longer distance measurements, increased speed and accuracy.
Almost any sensor yields more interesting results if mounted on a moving platform. Remember scanning thermometer? It’s time to mount TOF LIDAR (Time Of Flight / Light Imaging, Detection, And Ranging) on two precision rotary stages arranged for pan and tilt operation. Rig provides real-time position data along with distance to an obstacle. Using simple math we can calculate position in Cartesian coordinate system. Data is collected point by point to reconstruct 3D object model.
