Cisco chip exec sees steady ASIC investments
“Our investments [in ASICs] have been and continue to be large,” said Dan Lenoski who manages a team of about 125 of Cisco’s 750 chip designers. “That investment has been steady and increased since in 2000 because communications interfaces are getting faster,” Lenoski explained.
The raw number of ASIC designs may have declined over the years due to greater silicon integration, said Lenoski. Still, Cisco launches as many as several dozen new ASIC programs annually. It is widely regarded as one of the world’s largest ASIC developers and hosts its own annual “Chips at Cisco” conference for its engineers.
“The future in our mind is clearly [about] continued investment,” said Lenoski. “We do see merchant silicon sometimes filling our needs, but we can’t do packet processing and forwarding at the rates we want to hit and control our destiny without our own silicon.”
For example, Lenoski’s team, which designs chips for Cisco’s data center group, recently announced Monticello, a 40-nm chip that powers the company’s Nexus 3548 switch. The 412-mm2 chip packs 2.5 billion transistors delivering 48 ports of 10 Gbit/second Ethernet with 250-nanosecond latency in standard mode and as little as 50 nanoseconds in a dedicated mode. The latter is geared to Wall Street’s high-frequency traders and other speed demons
“We had never fully optimized for latency before, so we looked at everything from packet processing to queuing and output on a single chip with shared memory doing cut-through switching,” said Lenoski. “We have a number of experts in networking, silicon and the customer applications, and it’s the combination of that knowledge that lets us do these things,” he said.
The near-GHz chip is one of several 40-nm designs now in shipping Cisco products. “We have a number of 28-nm designs in the pipeline, but we are not in a lot of production at 28 nm yet,” Lenoski said.
The company’s ASICs serve a range of systems including high-end, processor-intensive routers and boxes that push the limits of virtual switching or pack an outsized number of 40- and 100-Gbit/s interfaces.
Proponents of the OpenFlow initiative said the trend toward centralized software-defined networks will radically simplify the tomorrow’s routers and switches. Lenoski doesn’t buy that.
“There are real-time constraints and reachability issues because switches and routers are distributed, deployed all over the place, and they are not one-to-one connected to servers,” Lenoski said. “So I think a lot of functions will stay in switches and routers, but the ability to program and understand the network [centrally] will increase over time,” he added.
Intel may be Cisco’s foundry
Intel is talking to Cisco about becoming its foundry, says investment bank Piper Jaffray.
According to the bankers, the deal could be worth $1 Billion a year to Intel.
Cisco would be Intel’s fourth announced foundry partner but by far the biggest. The other three announced partners, and there are said to be other unannounced partners, are Achronix, Tabula and Netronome.
Netronome is a network processor company from Santa Clara, California Intel’s home town, with whom Intel has been working for five years on development but onlt signed up for foundry services earlier this year. Under the agreement, Netronome also gets to use Intel’s own EDA tools.
Achronix and Tabula are FPGA companies. Achronix was the first, signing up for Intel foundry in 2010.

ROMS Parallel Framework:
- There are four different modes of computations in ROMS: (i) serial, (ii) serial with tile partitions, (iii) parallel with the shared-memory (OpenMP) protocol, and (iv) parallel with the distributed-memory (MPI, MPI2, OpenMPI) protocols. Mixed shared- and distributed-memory computations are not possible neither available in ROMS.
- ROMS has a coarse-grained parallelization design that allows the application domain to be partitioned into horizontal tiles. There is not vertical tiling in ROMS. Each tile is operated on by different parallel node or thread accelerating the computations substantially. The number of parallel tiles in the I- and J-directions are specified in NtileI and NtileJ standard input parameters. Each tile contains the physical points ranging from Istr:Iend, Jstr:Jend and Kstr:Kend plus the ghost (halo) points (usually, Nghost=2 but sometimes Nghost=3) that allow the computations of the horizontal gradients within each tile, privately. The value of Kstr is either 0 (W-points) or 1 (RHO-points) and Kend is N (number of vertical levels) always.
The extended bounds (labelled by suffix R) are designed to cover also the outer grid points (outlined above with :), if the subdomain tile is adjacent to the physical boundary (outlined above with +). Notice that IstrR, IendR, JstrR, JendR are only relevant for the tiles next to the domain boundary.

- All the global state arrays are allocated as (LBi:UBi, LBj:UBj, ...). The values of LBi, UBi, LBj, and UBj depend on the number of ghost points and if you are running in distributed-memory or not. In distributed-memory, their values are only bounded by the tile limits. For example, it is possible to allocate the bathymetry as h(48:102, 148:182) for a tile having two ghost points (Nghost=2) and Istr=50, Iend=100, Jstr=150, Jend=180. Contrarily, in serial and shared-memory applications, the allocation values correspond to those for the full grid: LBi=0, UBi=Im+1, LBj=0, and UBj=Jm+1. Check globaldefs.h to see how these values change in periodic applications. All these parameters are computed in several routines in get_bounds.F before the state arrays are allocated.
- The private automatic arrays are dimentioned as (IminS:ImaxS, JminS,JmaxS, ...) and include additional points to compute the spatial derivatives, locally, without the need to communicate with the neighbor tiles. This is a very important feature in ROMS and vital for parallelization.
- All the computations in ROMS need to be bounded by the tile limits of Istr:Iend and Jstr:Jend. Any assigment outside of these ranges is illegal and a serious parallel bug. Recall that mostly all the computations in ROMS are inside of parallel regions. For example:
In distributed-memory, the token TILE is replaced by MyRank during C-preprocessing. Otherwise, it is replaced with the tile variable. Users should never monkey around with this logic. This strategy allow us to have both shared- and distributed-memory cohexisting in the same code.
Code: Select all
!$OMP PARALLEL DO PRIVATE(thread,subs,tile) SHARED(ng,numthreads) DO thread=0,numthreads-1 subs=NtileX(ng)*NtileE(ng)/numthreads DO tile=subs*(thread+1)-1,subs*thread,-1 CALL step2d (ng, TILE) END DO END DO !$OMP END PARALLEL DO
- ROMS provides an extensive user interface to its kernel with the analytical options in the Functionals directory. Users should be extremely carefull when adding code to these routines. All these routines are called inside of a parallel region:
So all the required input fields are either interpolated from snapshots of data from input NetCDF files or specified with analytical functions. This is all done in parallel
Code: Select all
!$OMP PARALLEL DO PRIVATE(thread,subs,tile) SHARED(ng,numthreads) DO thread=0,numthreads-1 subs=NtileX(ng)*NtileE(ng)/numthreads DO tile=subs*thread,subs*(thread+1)-1,+1 CALL set_data (ng, TILE) END DO END DO !$OMP END PARALLEL DO
- If you do not understand this parallel design and what the coding rules are, you need to avoid using the analytical options and use input NetCDF files instead It is much easier and faster to create a NetCDF files than understand all the technical aspects of parallel coding which include false sharing in OpenMP, messages broadcasting, exchange, and global reductions in MPI. By the way, PRINT, READ, and WRITE statements need to be done correctly. Otherwise, you will introduce a parallel bug or get surprising results. We are usually very busy and cannot debug your customized code. We try very hard to give you a free and full working parallel model.
- I corrected recently the routine ana_psource.h. Applying the point source in this routine is extremely difficult, as you can see. I spent several hours in the debugger making sure that this work in all the four modes of computations in ROMS. If you do not understand the coding in this routine, I recommend to you to avoid modifying this or other routines in ROMS. For input forcing, use NetCDF files instead. Even if you understand or are familiar with parallel coding, you still need to do a lot of debugging to make sure that it is coded correctly There are no exceptions to this rule. You always need to debug and test.


FDA News Release, "FDA approves first implantable hearing device for adults with a certain kind of hearing loss" (March 20, 2014).
FDA has approved the first implantable device for adults with severe or profound sensorineural hearing loss of high-frequency sounds in both ears, but who can still hear low-frequency sounds with or without a hearing aid. The Nucleus Hybrid L24 Cochlear Implant System, manufactured by Australian firm Cochlear Ltd., combines the functions of a cochlear implant and a hearing aid. The technology includes an external microphone and speech processor that picks up sounds from the environment and converts them into electrical impulses. The impulses are transmitted through small implanted electrodes to create a sense of sound that the user learns to associate with the mid- and high-frequency sounds they remember. Of the 50 people studied in the clinical trial, 68% experienced some adverse events such as low-frequency hearing loss, ringing in the ear, electrode malfunction and dizziness. However, the FDA determined that the overall benefits outweighed this risk for people who do not benefit from traditional hearing aids.

mod_qos module can be used to set the Differentiated
Services field (RFC2474)
of IP packet headers. This can dramatically aid in the handling of these
packets in the network, depending on the network QoS configuration.
This module is contained in the
mod_qos file for
ProFTPD 1.3.x, and is not compiled by default. Installation
instructions are discussed here.
The most current version of
mod_qos is distributed with

4D Technology’s PhaseCam® MWIR is a dual-port infrared interferometer with blazing fast acquisition, even in turbulence, over long paths, or in vibration.
The PhaseCam MWIR measures optical surface shape and wavefront error at a 3.39 µm infrared wavelength. This unique Twyman-Green system lets you switch between two different optical test beams without changing the setup. At the turn of a knob measure through the system’s main aperature or through the side port, which can be coupled to a beam expander.
It’s like having two optical test stations in one setup.
The Twyman-Green configuration of the PhaseCam MWIR significantly reduces diffraction artifacts versus Fizeau interferometers. Diverger optics, for measuring concave optics using the main aperature, are smaller, less expensive and easier to work with than Fizeau transmission spheres, and create fewer measurement artifacts as well. Zinc-selenide lenses even permit alignment using a visible light alignment laser, making setup faster and easier.
100mm and 150mm aperture beam expanders are available for use with the side port as standard options, and 300mm aperture beam expanders are available for quote. The PhaseCam is kinematically mounted to the beam expander breadboard, so it can be easily moved to and from a different measurement station without disturbing the beam expander and test setup.
The PhaseCam MWIR can be operated in on-axis temporal measurement mode or in dynamic spatial carrier mode for challenging environments, such as turbulence, long paths or vibration, which are common in vacuum chamber or cryo-chamber setups.
While the standard PhaseCam MWIR uses a 3.39 micron source, custom options are available between 3.8 µm and 4.1 µm.


At the end of July, the Town completed a comprehensive upgrade to the Public Safety Radio System serving Fire, Police, Ambulance Corps and Public Works vehicle and hand-held mobile radios. The new system uses state-of-the-art simulcast radio technology and substantially improves coverage and the ability of first responders to operate safely and provide security to residents throughout town.
Planning for this $2.3 million system upgrade began in 2014 when significant radio system deficiencies were identified. In the Northwest and West portions of town, first responder portable radios received poor signal reception and, in some cases, no reception at all. In addition, the computerized backbone of the old radio system was aging and nearing obsolescence. The old system had a “single-point-of-failure” design, with broadcasting antennas only on the Waveny Water Tank, which exposed the town to losing its entire public safety radio system in a severe storm. The age and condition of the system was in dire need of an overhaul.
The five-year upgrade project was led by Stuart Sawabini, a former Chairman of the Police Commission and a director with New Canaan’s Community Emergency Response Team (CERT), Deputy Police Chief John DiFederico, and Public Works senior engineer Joe Zagarenski. The upgrade planning and implementation process required about 35 presentations and cross departmental coordination with various authorities resulting in national, state or town oversite. After extensive testing, the town, particularly the Northwest portion and West School, have vastly improved coverage.

* * * What is a port knocker? * * *
With port knocking you can secure services behind a firewall and if you need to connect to them you must send the specific port knocking sequence first. Afterwards, the requested port gets opened.
Here is a simple example: imagine you have SSH installed on your server but don't want to open the SSH port (usually 22) to everybody. In fact, you can just install a port knocking daemon and secure the SSH port behind a firewall. If you now want to connect to your server using SSH you can't do so until you have sent the port knocking sequence that opens the firewall for your current IP address.

Cabling specialists sometimes have to decide whether to use fiber optic or copper cable when installing a network. They have to consider things like cost, transmission speed, device accessibility and other factors. Compared to copper cabling, fiber optics are relatively new on the market. In the networking industry, there’s an ongoing debate as to which type of cabling has more advantages and each side has several valid points.
The basic function of both fiber optic and copper cabling is to send signals over a distance, but their differences lie in how each type manages to do that. If you hope to pursue a career in network cabling, it’s important to know the differences between the two technologies so that you can decide for yourself which one would be best to use on a particular job.
Read on to learn more about differences between fiber optic and copper cabling and to find out the advantages each one offers!
Network Cabling with Copper
When it comes to telecommunications, several types of copper cabling are typically used:
- Twisted pair cabling is the most popular network cable and is often used in data networks for short and medium length connections
- Unshielded twisted pair (UTP) cables are the primary cable type for telephones
- Coaxial cables are popular for computer network (Internet) and instrumentation data connections, video and CATV distribution
All forms of copper communication work by sending electrical pulses through copper wire. If you’re planning to enroll in a network cabling program, here are some advantages of using copper cabling on an installation:
- Power over Ethernet (PoE): This gives you the ability to power phones, surveillance cameras, Wireless Access Points (WAPs), and other devices right through the networking cable itself.
- Cheaper electronics: Most computers come with copper Network Interface Controller (NIC) cards. This is good to keep in mind for offices that require multiple computers to be networked. Optical NICs can cost up to $200 each.
Network Cabling with Fiber Optics
Fiber optic communication uses light signals to transmit information. Light travels through a series of reflective glass tubes within a cable, which can be beneficial when you’re trying to transfer data over long distances.
They may cost a little more, but network cabling career training will teach you that there’s several advantages of using fiber optics in a cable infrastructure, such as:
- Non-flammable: There’s no electrical current that flows through fiber optics. Copper, on the other hand does carry a current and can become a fire hazard once it starts getting worn.
- Faster transmission: Copper suffers from a significant signal-loss issue. Information travels through fiber optics at 70% of the speed of light.
- Lightweight: An optical cable weighs less than a comparable copper wire cable.
- Electromagnetic Interference (EMI): Copper cabling is at risk of being affected by EMI, and is vulnerable to undesirable responses, degradation, or complete system failure. Optical fiber is immune to electromagnetic energy because it is a dielectric (it doesn’t conduct an electrical current.)
If you’re pursuing a career in network cabling, you probably know that both types of cabling are reliable. In the end, when a network cabling specialist is trying to decide what type of cable will work best, it’s good to have options!
Do you know of any other advantages of using fiber optic versus copper cabling?

In “the old days”—before direct-dial telephones—one would ring the operator and she would connect you to your desired party. In the event of an emergency, the operator (who was often local) would connect you with the fire department, police or a doctor (whom she happened to know was in-town at that moment). As phones became more common, and networks were upgraded to “direct dial” systems, getting emergency help became more complicated—and took longer.
On this day in 1937, London instituted the world’s first city-wide emergency response number: 999. Anywhere within London, one could dial 999 and be connected to an emergency services operator who would despatch the appropriate emergency services or advice. Other towns and municipalities followed-suit, each creating its own emergency response number. In time—again, as phone service became more universal—complications arose because each town or hamlet had a different number. In time these numbers were streamlined to a common, national number (like 911 in the United States). Most countries today have a single emergency response number. Canada uses 911 while most of Europe uses 112.
America’s 911 emergency number was first used in Alabama in 1968. It wasn’t until the 1980’s, however, that the United States finished changing its various emergency numbers into the universal 911. Nevertheless, there are still parts of the rural U.S. that are not connected to 911.

NEOMATECH Infrastructure services helps enterprises Design, Build and Manage a highly flexible , scalable and reliable IT Infrastructure.
NEOMATECH is dealing with Structured cabling. Structured cabling is the design and installation of a cabling systems that will support multiple hardware uses systems and be suitable for today’s needs and those of the future. With a correctly installed system your requirements of today and of tomorrow will be catered for and whatever hardware you choose to add will be supported
A properly designed and installed Structured cablingsystem provides a cabling infrastructure that delivers predictable performance as well as has the flexibility to accommodate moves, adds and changes; maximizes system availability, provides redundancy; and future proofs the usability of the cabling system.
With an unorganized messy cabling infrastructure, mistakes are commonly made. Incorrect ports are unplugged. Even worse is the messy cabling that gets in the way. Trying to remove a single cable from a large tangled mess can cause stress on the other cables. This stress can lead to network and channel errors in the hardware that are very difficult to trace


The signals from the antenna pass through a double-tuned band-pass filter consisting of T1 and T2 tuned by a dual-section variable capacitor. L1 provides negative mutual inductance between the two tuned circuits to maintain a constant bandwidth of approximately 12KHz across the entire 530 to 1700KHz tuning range.
The secondary of T2 applies the RF signal to the signal grid of the 12DZ6. Amplified RF on the plate of the tube passes through a fixed 500-1700KHz band-pass filter consisting of two 2.5mH inductors and an 18pF capacitor and is applied to the 1N34 detector.
The audio output of the detector is low-pass filtered by a 0.001uF cap to remove residual RF and is applied to the primary of the first audio transformer via the 100K-ohm volume control. (Yes, the radio is sufficiently "hot" to need a volume control.) The transformer provides voltage gain for the audio signal and additional rejection of RF present in the detector output. A 15K resistor bypassed by a 1uF cap in the ground return of the transformer primary ensures that the detector sees a proper DC load under all circumstances to avoid audio distortion.
Audio from the first AF transformer secondary is applied to the grid of the tube through the secondary of T2. Amplified audio on the plate of the tube passes easily through the 2.5mH RF choke and is applied to the primary of the audio output transformer. A 300-ohm secondary impedance was chosen to match an available sound-powered headset to achieve maximum possible acoustic output. This elaboration proved to be overkill.
The 12DZ6 and similar tubes provide much greater gain than was available from the early triodes used in vintage reflex sets. Therefore, a lot of attention needs to be paid to careful grounding and shielding and proper design of the various filter and bypass circuits in order to avoid oscillation. If this radio whistles like a regen, it's not working properly.

Ideally, a grid operator would know seconds, minutes or hours in advance what the power output from wind power will be. With current forecasting and data exchange models this is impossible. The ENERGIX project partly funded by the Norwegian Research Council carried out by WindSim Nowcasting with data input from Breeze aims to make the impossible possible.
Electricity generation from wind has grown annually by double digits for the past decade. With greater penetration, wind’s inherent resource volatility becomes increasingly challenging for transmission and grid operators who need to react quickly to changes in energy output. Ideally, a grid operator would know seconds, minutes and hours in advance what the energy output from wind assets will be – something that has not been possible with existing forecasting and data exchange models. The ENERGIX project aims to make this possible.
ENERGIX is funded by The Research Council of Norway (Forskningsrådet), and is performed by WindSim with real-time data input from the Breeze wind farm management system.
The ENERGIX project is built around real-time data sources that are seamlessly routed through the Breeze platform to the WindSim Nowcasting forecasting model and the results back into Breeze. The Breeze API (application programming interface) enables owners of wind farms to provide other actors in the value chain with the expected energy output. Nowcasting data provides grid operators with more flexibility to plan transmission capacity and back up generation.
WindSim Nowcasting will combine real time production data with numerical weather prediction, artificial neural networks and computational fluid dynamics (CFD) to predict the energy production of turbines for the next minutes and hours. Nowcasting will help inform all decisions related to energy transfer.
Further Applications of Nowcasting
Nowcastings can also be used for performance optimization. Nowcastings, together with more open turbine control systems, will enable turbine owners to develop strategies to optimize production from wind farms as a whole, not just individual turbines, and to reduce blade stress due to turbulence, for example.
The cooperation with WindSim on the ENERGIX project highlights one of many possibilities enabled by Breeze’s powerful API. For more information about Breeze for wind farm management and other API applications, please contact us.
The ENERGIX project commences Q1 2015 and ends Q4 2016.

After taking its own time, Nokia has finally decided to venture into the market which iPhone is ruling. With the Nokia Tube, the first touch device of the series 60, getting unveiled tomorrow, the leaders of mobile market would pose a strong competition for the Apple iPhone 3G.
Comparing them head to head:
|Phone Network||EDGE, GPRS, GSM, HSDPA (3G), UMTS (3G)||EDGE, GPRS, GSM, HSDPA (3G)|
|Bluetooth||Version 2.0 with A2DP||Version 2.0|
|Main display||Color TFT touchscreen||Color TFT touchscreen|
|Color display||16.000.000 colors||16.000.000 colors|

|Battery||BL-5J 1150mah Battery||Standard battery, Li-Ion|
|OS||Symbian S 60||Mac OS X v10.4.10|
With Nokia’s Tube matching and excelling the features of the IPhone in the comparison, experts say that the sales of the Tube would depend upon the price of the phone which would decide result of the war. But I would say the war has just begun. With Blackberry’s touch phone which is to be released in early Jan and advanced version of the 3G iPhone still in the pipe, the touch market is still seeing its dawn.


Danube Tower (Donauturmstrasse 4, Vienna) – known locally as the Vienna Donauturm, this tower (opened in 1964) is the tallest structure on Austria (standing at 252 meters), and is listed as among the 75 tallest towers in the world. Located in Donaupark, it is a popular tourist attraction – with two high-speed elevators to take passengers to the tower’s viewing platform (at the 150 meter level).

Wired camcorders are more common, but wireless home security camcorders are also available. Wired cameras use Wi-Fi to transfer video, even though wireless camcorders rely on a wireless network interconnection. Then, you will see the video from the computer or synced mobile phone. Wired and wireless video security cameras are evenly convenient. And perhaps they are affordable. Listed below are the pros and cons of both. Read on to create an informed decision. Below are a few things to consider think about a security camera.
Wired: Several home security surveillance cameras connect to a hard drive or digital video recorders for storage. In the case of cordless security cameras, the footage can be stored around the cloud. Wired cameras connect into a coaxial cable to capture footage and store this on a hard drive. However , wi-fi cameras are definitely not truly wirefree because they need an external electrical power source. If you would like to use a wifi security camera, check that it’s compatible with your home WiFi network.
Wi-fi cameras are easier to set up. However , they rely on impair storage and will be inclined https://thevirtualdata.com/ to hackers. A spotty wi-fi connection can easily prevent you from getting clear online video feeds. A better choice would be a wired camera. A wired camera requires professional setup and require cloud storage. An invisible security camera must be compatible with your router and switches to job. If you have a Wi-Fi network, you should replace the default username and password of your home network before putting in it.

Certificate Management – A Critical Part of Physical Security
Enterprises today rely on a massive number of physical security devices and sensors – such as surveillance cameras, access controls, and alarm systems – to secure their premises, people, IP, and other assets. Each of these devices comes with its own security certificate which must be tightly managed to ensure the device is compliant and functioning as expected. If physical security devices are not available or operating as designed, the results can have a severe impact on the enterprise — from unprotected assets to unauthorized access. This blog does a deep dive into the essential role that security certificates play in physical security device management.
What are device security certificates?
A device certificate is a digital certificate that enables the identification, authentication, and secure communication between two devices using a Public Key Infrastructure (PKI). Simply put, a device security certificate serves as a form of digital identity and allows devices to verify the trust status of other devices attempting to access their network. They do this by authenticating the organization’s name registered on the certificate and enabling data security through encryption. Without a digital certificate, a device cannot connect to the network, even if it is registered as a valid device.
Why are device security certificates so important?
Each device’s security certificate comes with a set of cryptographic keys, one to encrypt outgoing data and the other to decrypt incoming data, so a device certificate enables other devices to verify that the device trying to connect with it is legitimate. This ensures secure communications between the two devices while preventing unauthorized users from accessing that data. This is especially important in today’s era of cyberattacks. IoT devices are preferred targets of threat actors seeking easy ways to intercept company data or breach the device itself. Imagine the damage that can ensue if a hacker shuts down your organization’s security cameras or breaches your access panels.
Certificate rotation – replacing an existing certificate with a new one – every six months or less is considered a best practice for securing IoT physical security devices. While every organization has its own certificate issuance and life-cycle policies, rotating certificates help prevent outages and tracking these certificates highlights upcoming expirations and out-of-date issues.
Why is certificate management so challenging?
While organizations generally understand the operational benefits of using device security certificates for their physical security devices, these digital certificates are not always properly managed. That’s because organizations often rely on manual and time-consuming processes managing certificates on their physical security devices. This lack of efficiency results in multiple issues:
Unmanaged certificates: Most physical security devices do not have authentication certificates installed, and when present, they are rarely changed.
Unsecure communication channels: Communication with physical security devices often occurs via unsecured channels. Even with an encrypted connection, the identity of a device with no valid certificate cannot be verified, allowing traffic to be intercepted, and risking data integrity.
Self-signed certificates: Some devices use self-signed certificates. Security risks are introduced when device certificates are signed with their own private key, as opposed to being signed by a private or public Certificate Authority (CA).
Costly, time-consuming & manual operations: Manually managing security certificates for a fleet of devices is expensive and time-consuming. Any manual processes are prone to error and thereby increase risk.
Workflow gaps: Organizations are often missing official single certificate request workflows, as the workflow is often too difficult to implement. This gap opens the door to added risk.
Compliance issues: Any of these potential points of failure may lead to compliance issues.
Added complexity: The process of implementing end-to-end certificate management for 802.1x certificates on IoT devices has additional complexity. Several risks are associated with the success of the end-to-end 802.1x certificate management process, including loss of connectivity in the network infrastructure, reliance on device configurations, and its dependencies.
The case for automation
With the increasing number of deployed physical security devices, reliance on manual processes becomes less and less feasible. Enterprises have been turning to automation to complement their physical security teams by centralizing and automating the operational management of their physical security devices, including certificate management. Automating the operational management processes associated with physical security devices has been proven to both streamline ongoing tasks in an efficient manner, and deliver immediate cost savings and clear ROI.
This ROI comes from enabling visibility into the health status of all physical security devices on the network, which in turn keeps devices operational 24/7, and drives faster issue resolution, decision making, and future planning. At the same time, automation reduces the need for truck rolls and on-site visits, and frees up staff from time-consuming manual tasks.
The way forward: SecuriThings Enterprise
SecuriThings Enterprise is a software-only solution that introduces the concept of IoTOps — a set of practices that combines IoT operations and IT operations. It aims to empower organizations to operationally manage physical security IoT devices at scale in a consolidated and automated manner.
With the SecuriThings certificate management functionality integrated tightly into the organization’s security processes, the organization can improve its certificate rotation processes in coordination with its CA. Detailed compliance policies can be defined and implemented, with SecuriThings monitoring compliance in real-time and with visibility to adherence. Features include:
- Centralized inventory and compliance reporting
- Bulk certificate rotation for devices and groups of devices
- Discovery of all the SSL and 802.1x certificates deployed across devices
- End-to-end certificate life cycle management with the organization’s CA
- Secure connection with the device during the process (MiTM protection)
- Full control of the certificate parameters and flexible configuration, allowing control of the common name, key size, set email address, and more.

How Does an Audio Interface Work?
At the very core, the job of an audio interface is to enhance the sound output of a computer. They are a lot like sound cards but because of how they work they are able to offer a considerably better performance than sound cards.
Most computer sound cards or outputs are not meant for high-resolution output. Therefore, they are insufficient when it comes to music production.
Moreover, an audio interface works in preparing sound that you put into your computer.
An interface makes sure that the user is able to record quality, high-resolution sound.
However, before getting a basic understanding of how an audio interface works, we must understand what an audio interface is.
What Is an Audio Interface?
The device works by converting analog signals into digital audio.
This makes your audio computer readable, and the computer is able to process it like any other information.
The audio interface sends digital audio to a computer through a medium.
This medium connection can be anything from a special PCI/PCIe card, USB to FireWire or Thunderbolt.
The device can perform the same job in reverse as well.
It receives digital information and converts it to analog signals.
These analog signals can then be heard through headphones, speakers or studio monitors.
It’s common for audio interfaces to have line-level analog inputs or outputs.
They can also include one or more preamplifiers for microphones and even digital inputs/outputs like AES.S/PDIF or Lightpipe.
When Do You Need an Audio Interface?
As discussed before, both sound cards and audio interfaces are not very different.
At its base, the sound card is also an audio interface.
However, sound cards have limited capabilities and aren’t ideal when someone wants to record audio.
Sounds cards are meant for general use. This means that they only have consumer-grade stereo line-level input /output.
Moreover, factors like electromagnetic and radio interference, excessive latency and jitters degrade sound quality.
Keep in mind; it’s impossible to record a full drum kit with just two channels for input.
Sound cards are ideal if you have less-demanding needs for audio.
So, playing back compressed audio or connecting a couple of Hi-Fi speakers is fine.
However, you’ll need an audio interface if you want to record or monitor production quality audio.
Choosing Suitable I/O Configuration for Audio Interfaces
There are a few considerations that are as important as choosing a suitable I/O configuration for your audio interface.
You have to consider what you will need to record now or in the future while deciding on the number and types of inputs/outputs.
There’s a lot of variety in the type of audio interfaces you can choose from.
You can choose everything from a 2-channel desktop unit to a system that records hundreds of channels.
For singers or songwriters, a pair of units is sufficient as long they choose the right ones.
The majority of interfaces have two or more microphone preamplifiers.
While using a condenser microphone, it essential to equip your interface’s preamp with phantom power.
However, if you plan to plug your guitar straight into the audio interface, make sure that your interface has instrument level or “hi-Z” inputs.
You shouldn’t forget that line-level inputs are ideal for headphone amps, outboard processors and studio monitors.
People tend to disregard the importance of digital I/O when they’re starting out.
But, they can prove to be useful later-on.
For example, few high-end one or two-channel microphone preamps are equipped with digital outputs.
This enables users to connect those preamps with their audio interfaces without removing line-level inputs.
Audio Interface Computer Connectivity Options
However, there are a few audio interface connection types that are still considered as standard.
Some of these are FireWire, USB, Thunderbolt, and PCIe.
Most computers (both PCs and Macs) have to cater to USB ports with version 2 or 3.
FireWire (400 or 800) is still more common in Mac.
The average speed of both these packages is 480 Mbps. Under ideal conditions, you can record up to 64 tracks through this speed.
Yet there are simple interfaces that still support USB 1.1. This can be quite slow, but you can record one or two channels.
Technical Specifications in Audio Interfaces
How to read them?
Bit depth and sample rates are important specifications for any audio interface.
Bit depth has a significant impact on sound when you’re processing audio.
This means that CD-standard 16-bit audio has a total range of up to 96dB.
Problems arise when the digital noise floor is high, and the remaining range is small.
When working at 16-bits, the quieter section of your audio will have sudden noise.
Professionals recommend working with 24-bit at a dynamic range of 144dB.
On the other hand, the choice of sampling rates can vary according to what you intend to do with your audio.
If someone is planning to release demos on CD or wants to post MP3s, it’s ideal to work at or mix down to 16-bit/44.1 kHz.
For professionals who wish to release jazz in high-resolution, it would be disastrous to work at less than 24-bit/96 kHz.
Sampling rates as high as192 kHz are useful for sound design.
You can try the old trick of recording a dog snarl at 192 kHz and mixing it with a session of 96 kHz (without losing any resolution).
This will result in giving you the traditional monstrous growl you have heard in most sci-fi movies.
Additional Considerations for Audio Interface
Eager professionals should remember some other considerations as well.
There are still a few audio interfaces that are only compatible with either PC or Mac.
Before buying one for yourself, see if the audio interface will work in sync with your machine or not.
Many interfaces include handy features like embedded software control and DSP for mixing.
Software mixing allows professionals to do special tricks with their interfaces.
They can do everything from adding reverbs, setting up headphones mixes or delaying headphone mixes.
You can also do talkback communication with artists in the studio.
Moreover, you can do all this on an onboard DSP without increasing latency, affecting DW software or draining your CPU power.

The MediaTek Dimensity 820 will attain 2.6GHz CPU clocks
MediaTek has scheduled an occasion for Monday (Could 18) to unveil a new 5G chipset. The Redmi Observe 10 which surfaced on TENAA would be the first cellphone to make use of it and if it’s not, there’s a very good probability that will probably be the Redmi Ok30i 5G as an alternative. Redmi Normal Supervisor and Xiaomi VP Lu Weibing reposted MediaTek’s announcement, lending some credence to the rumors.
The brand new chipset shall be known as Dimensity 820. We’ve additionally heard 800+, which traces up with the naming scheme of the Dimensity 1000+. Both means, the brand new chip will provide a efficiency enhance - TENAA reveals that the CPU will attain clock speeds as much as 2.6GHz, up from 2.0GHz on the Dimensity 800.
Rumors recommend MediaTek will swap to a 2+2+four CPU setup with two prime cores at 2.6GHz, two large ones at 2.2GHz and 4 small ones at 2.0GHz. The corporate will probably follow the 4 Cortex-A76 and 4 A55 combo of the 800 chip (which runs all eight cores at 2.0GHz).
There might be greater than that, in fact. For instance, the Dimensity 1000+ added help for 144Hz screens, lowered energy utilization and improved 5G and Wi-Fi 6 connectivity.
Anyway, with the brand new Dimensity chipset coming Monday and the repost from Lu Weibing, we anticipate to see Redmi unveil its first cellphone (or telephones) with it fairly quickly.


You Don’t Know Jack? Part 3
Now its time to introduce a jack that most associate with the “professional”world….the XLR! In this case, the XLR3
The XLR3 carries three signal wires, usually a positive, negative and a ground. It is extremely important to know how your gear is wired, as the AES standard is pin 2 hot, but many manufacturers go with pin 3 hot. Check with your multimeter to be sure!
The XLR is commonly used in the analog world for microphone cables and balanced, line level cables, and in digital audio as the connector for the AES/EBU digital audio format.

Silicon carbide micro-ring all-optical processor
Silicon (Si) photonics are able to overcome the transmission degradation induced by the limited RC time constraint in electronic integrated circuits via electro-optical switching or all-optical processing. Si photonic components, including light sources1, waveguides2-3, and photodiodes, have been developed to construct all-optical transmission platforms on a chip. When considering the optical processing, optical excitation or electrical injection can change the absorbance and refractive index or induce free carriers in Si-based materials, which facilitates switching and modulation via ring resonators or Mach-Zander interferometers. Nevertheless, the free-carrier lifetime in bulk Si remains beyond the nanosecond range, thus limiting the switching or modulation bandwidth. Using the optical nonlinearity of Si is an alternative way to realize the same functionality for all-optical data processing at a high speed in next-generation devices. Two major all-optical switching mechanisms, including two-photon-absorption (TPA)-induced free-carrier absorption (FCA) and the nonlinear Kerr effect, have been considered; however, TPA-induced FCA modulation requires more time to dissipate free carriers, which delays the device response. Meanwhile, nonlinear Kerr switching is another way to achieve ultrafast data processing under a high-intensity pump or with a strongly nonlinear refractive index.
In Si photonics, the bulk Si integrates many optoelectronic components on a chip. However, bulk Si has some limitations for all-optical modulation, even when it is compatible with CMOS fabrication technology, and it exhibits a small nonlinear refractive index that practically limits its application in nonlinear optical processing. Additionally, FCA dominates the switching mechanism in bulk Si and degrades its high-speed performance. In contrast, Si carbide (SiC) has emerged as an alternative because of its stronger nonlinearity than that of other Si-based materials, which also provides a higher thermal stability to enable operation at higher intensities. Therefore, SiC is a potential candidate for performing high-speed data processing based on its optical nonlinearity. In this work, a SiC-based ring resonator is used to demonstrate high-speed cross-wavelength wavelength conversion and format inversion by employing the nonlinear Kerr effect, as shown in Fig. 1.
The Si quantum dots embedded in SiC induce quantum confinement to increase the nonlinear refractive index of the SiC material to as high as 310-13 cm2/W. This enhanced nonlinear refractive index temporarily contributes to a redshift of 0.07 nm in the transmission spectra under high-intensity injection, as shown in the lower left part of Fig. 2. Under a data stream with a 12-Gbit/s pulsed return-to-zero on-off keying (PRZ-OOK) format, the SiC-based ring resonator can demonstrate wavelength conversion and data inversion owing to the nonlinear Kerr effect, as shown in the lower right part of Fig. 2. In addition, the signal-to-noise ratio of the modulated data stream is 9.4 dB with a penalty degradation of 2.6 dB relative to that of the optical pump. The rise and fall times of the inverted probe that are shorter than 43 ps remain identical to those of the pumping signal, indicating a distortion-free replication of the pumping format on the modulated probe.
