Network Radar 2.10 !!TOP!!
In Linkerd 2.10, the Linkerd control plane is now modular and extensible withthe introduction of extensions. Extensions are opt-in software componentsthat run as part of the Linkerd control plane. The default control plane in2.10 now contains just the bare minimum necessary to run, with Prometheus,Grafana, dashboard, and other non-critical telemetry components packaged as aviz extension. This change drops the default Linkerd control plane down to200mb at startup, from 500mb in Linkerd 2.9!

Ready to try Linkerd? Those of you who have been tracking the 2.x branch viaour weekly edge releases will already have seen these featuresin action. Either way, you can download the stable 2.10 release by running:
Doppler radars have been flying on research aircraft since the first prototype was tested in 1982.9 Airborne Doppler radars are advantageous for studying individual storm cells and mesoscale weather phenomena because:
Airborne Doppler radars scan towards the front and the rear of the aircraft, which yields two wind components for each location in the atmosphere (Fig. 2.9). When the principles of conservation of momentum and mass are applied to those data, a three-dimensional view of the atmosphere can be produced. Some limitations of airborne Doppler radar are: flight legs must be relatively straight, and the accuracy of radial velocity is within 1.5 m s-1 due to aircraft motion (corrections must be made for the movement of the aircraft).12,13 Aircraft operations are expensive and can, therefore, only provide limited spatial and temporal coverage.
New observations by airborne Doppler radars allow us to observe cellular and banded precipitation structures within the eyewall and rainbands of tropical cyclones (Fig. 2.10). Transformation of these structures has been linked to changes in the intensity of tropical cyclones.14 High resolution images are allowing scientists to examine fine-scale changes and relate them to structures predicted in theoretical studies and NWP models. Figure 2.10 shows a number of interesting features hitherto unobserved, such as filaments of very high reflectivity that are oblique to the concentric eyewall and rainbands. These structures are affected by varying winds as they move around the eyewall and provide clues about how eyewalls transform during rapid changes in intensity.
I have a Virtual Machine with Windows 7 Enterprise installed, NI MAX and Labview 2019. Under the network of this VM i have six cRIO (two of them are 9076 and four of them are 9053) which i can't find in MAX nor in Labview.
One of the difficulties with LabVIEW on a VM is dealing with hardware. You have to get the VM "Host" to pass the hardware signals it is getting up to the VM itself. What can you tell us about the VM? Is it a VMware VM, or a Microsoft VM, or some other VM? What about the hardware? I assume the cRIO is on a TCP/IP network -- can you "ping" it from the VM?
The WMO and the Association of the Southeast Asian Nations (ASEAN) ran the WMO/ASEAN Training Workshop on Weather Radar Data Quality and Standardization in Bangkok, Thailand, from 5 to 13 February 2018, with full support from JMA and the hosting Thai Meteorological Department (TMD). Radar experts from nine National Meteorological and Hydrological Services (NMHSs) in ASEAN members (Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Viet Nam) and Bangladesh attended, and JMA dispatched experts to give presentations and provide training. The Chair and Vice-chair of the WMO Inter-Programme Expert Team on Operational Weather Radars (IPET-OWR) and representatives of weather radar manufacturers in Japan and Germany also gave presentations.
This workshop was held to address common regional challenges in extreme weather monitoring and forecasting in Southeast Asia. The installation of numerous weather radars in the region has led to an increased need for effective utilization of the data collected. In addition, improved Quality Control (QC) and international real-time data exchange play pivotal roles in Disaster Risk Reduction (DRR) in the region. As a result, capacity-building in weather radar techniques is crucial for NMHSs in Southeast Asia.
At the beginning of the workshop, the leader of the Capacity Building in Radar Techniques in Southeast Asia project (a joint regional WMO Integrated Global Observation System (WIGOS) initiative conducted in Regional Association II (RA II) (Asia) and RA V (Southwest Pacific)) and the Chair of IPET-OWR delivered keynote speeches. Both highlighted the importance of the regional radar network in Southeast Asia, whose operation depends on firm capacity building in all NMHSs.
During the eight-day workshop, attendees learned all about weather radar via theoretical and practical sessions. The presentations given covered the basics, maintenance, dual-polarization technology, data Quality Control (QC) and Quantitative Precipitation Estimation (QPE) methods. The course also included hands-on training in QC and summarization of a disaster event using weather radar information and other types of meteorological data.
In the final stage of the workshop, attendees considered specific plans to enhance weather radar observation in their own NMHS and discussed ways to improve QC and expand the regional radar network in Southeast Asia. The consensus was that the network will benefit all NMHS and should be established via mutual cooperation in the region.
At this point, you have to understand a little of what teqcis trying to do. By default and if possible, teqc would tryto convert the input file(s) into the latest RINEX standard,which is now 2.10. (Using the +v option suppresses the outputas RINEX.) In most all cases, there is no forward compatibilityproblem with RINEX, i.e. files of version 1 or 2 (or 2.01) areeasily convertable to RINEX 2.10.
There is one situation where there is a problem, and that is with the WAVELENGTH FACT L1/2 header line(s). Like RINEX 2.10, teqc requires that there be a default WAVELENGTH FACT L1/2 header line, preceding any optional SV specific WAVELENGTH FACT L1/2 header lines. Some translators do notproduce RINEX OBS files with the now required defaultWAVELENGTH FACT L1/2 header line, which makes these filesfail with the +v option. The only solution is to edit thefile and insert the required default WAVELENGTH FACT L1/2 header line before any of the SV specific WAVELENGTH FACT L1/2 header lines.
For security reasons, you cannot set up an SSH tunnel from the managed host to the Console, but you can set up an SSH tunnel from the Console to the managed host. The managed host's public key is not added to the Console's authorized keys file. These SSH sessions are initiated from the Console to provide data to the managed host. For example, the QRadar Console can initiate multiple SSH sessions to the Event Processor Appliances for secure communication. This communication can include tunneled ports over SSH, such as HTTPS data for port 443 and Ariel query data for port 32006. QRadar QFlow Collectors that use encryption can initiate SSH sessions to Flow Processor appliances that require data.Using Tunnels adds additional layers to QRadar and can impact performance. If you are on a closed network, tunnels may not be the best solution. To improve performance, you might need to also enable Encryption compression. If you require encryption and the tunnel fails to add, look at the suggestions below to determine if you see similar error messages or issues with SSH.NOTE: Administrators are not able to SSH between managed hosts. SSH sessions must originate from the Console, or a root password is required when you SSH from the managed host to the Console. This is Intentional, and IP tables are configured in QRadar to prevent users from moving between managed hosts freely as part of our security protocols. One exception is that you can SSH from a QFlow to a Flow Processor. The flow will create the tunnel to a Flow Processor so that it can communicate with it.
So to be clear, the fix given for older versions of log4j (2.0-beta9 until 2.10.0) is to find and purge the JNDI handling class from all of your JARs, which are probably all-in-one fat JARs because no one uses classpaths anymore, all to prevent it from being loaded.
The #iw section describes how to manually manage your wireless network interface / your wireless LANs using iw. The Network configuration#Network managers section describes several programs that can be used to automatically manage your wireless interface, some of which include a GUI and all of which include support for network profiles (useful when frequently switching wireless networks, like with laptops).
The default Arch Linux kernel is modular, meaning many of the drivers for machine hardware reside on the hard drive and are available as modules. At boot, udev takes an inventory of your hardware and loads appropriate modules (drivers) for your corresponding hardware, which will in turn allow creation of a network interface.
Also check the output of the ip link command to see if a wireless interface was created; usually the naming of the wireless network interfaces starts with the letter "w", e.g. wlan0 or wlp2s0. Then bring the interface up with: 041b061a72
