Nikola Tesla Pop Art print
Nikola Tesla (1856 -1943) was a Serbian American physicist, inventor, electrical engineer, mechanical engineer and futurist best known for his contributions to the design of the
modern alternating current (AC) electricity supply system.
Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City.
He soon struck out onhis own with financial backers, setting up laboratories and companies to develop a range of electrical devices.
His patented AC induction motor and transformer were licensed by
George Westinghouse, who also hired Tesla for a short time as a consultant.
His work in the formative years of electric power development was involved in a corporate alternating
current/direct current "War of Currents" as well as various patent battles.

"Disorder-Immune Photonics Based on Mie-Resonant Dielectric Metamaterials"
Abstract: When the feature size of photonic structures becomes comparable or even smaller than the wavelength of light, the fabrication imperfections inevitably introduce disorder that may eliminate many functionalities of subwavelength photonic devices. Here we suggest a novel concept to achieve a robust band gap which can endure disorder beyond 30% as a result of the transition from photonic crystals to Mie-resonant metamaterials. By utilizing Mie-resonant metamaterials with high refractive index, we demonstrate photonic waveguides and cavities with strong robustness to position disorder, thus providing a novel approach to the band-gap-based nanophotonic devices with new properties and functionalities.

Additional info for Analog and Digital Filter Design
The Q of an inductor is given by the ratio of inductive reactance divided by its series resistance. Series source resistance or shunt load resistance is needed to limit the Q and to give a smooth passband response. Another effect of high Q values is that they would produce ringing at the output if an impulse were applied at the input. As more reactive elements are connected in a ladder of series inductors and shunt capacitors, so the rate of attenuation beyond the passband increases in proportion.
Highpass, bandpass, and bandstop filters can be produced by transforming the equations before frequency scaling. 1. In all of these ratios, the resultant frequency is always greater than one. 1 filter Scaling factors Digital Filters Signal Processing for the Digital World An important relationship between the time domain and the frequency domain occurs when two signals are multiplied together. This relationship is important in both digital filter design and radio systems. Consider signals “cosA” multiplied by “cosB,” where “A” and “B” are proportional to frequency.
Further information on group delay is provided in Chapter 9, which describes all-pass filters. All-pass filters have a phase response that can be used to correct group delay variations of band-shaping filters. All-pass filters can also be used to create Hilbert transform filters. These have two filter branches whose outputs have the same signal amplitude but with a 90" phase difference.

Advantages of Solar Energy
Renewable Energy Source
Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source. It can be harnessed in all areas of the world and is available every day. We cannot run out of solar energy, unlike some of the other sources of energy. Solar energy will be accessible as long as we have the sun.
Reduces Electricity Bills
Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage.
You can use solar energy for diverse purposes. You can generate electricity (photovoltaics) or heat (solar thermal). Solar energy can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited clean water supplies and to power satellites in space.
Low Maintenance Costs
Solar energy systems generally don’t require a lot of maintenance. You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. If in doubt, you can always rely on specialized cleaning companies.
Technology in the solar power industry is continuously advancing, and improvements will intensify in the future. Innovations in quantum physics and nanotechnology can potentially increase the effectiveness of solar panels and double, or even triple, the electrical input of the solar power systems.In 2017, The MIT lab team revealed a new tech concept that captures and utilizes the waste heat that is usually emitted by solar panels. This typically released and non-harnessed thermal energy is a setback and an opportunity for improvement for solar technology, which means this innovation could help the cost of solar to plummet even further.


What is an IP address?
Every machine connected to any network, whether it's a laptop, PC, printer, or a smartphone, always has a unique identifier. This identifier is the address of that machine on the network and it's called its IP address. So, just as we would address a letter to a postal address before sending it via mail, computers use IP Addresses to identify where/who to send and receive information to or from on a network.
Hence, the router which acts as a gateway between your office LAN network and the internet world, is identified via an IP address(es). Every time someone from your office LAN network connects to the internet, the machine they use for connected is identified via an IP address on your LAN.
What are IP restrictions on sumHR?
sumHR lets you define your office LAN IP address inside your sumHR account such that no other IP addresses (outside your office LAN network) are allowed to perform online attendance logging (clocking in/out).
This way, you can ensure that every employee who wishes to clock in or out, has to do it from a computer that's present in office.

Infrared light waves range between the light that humans can see unaided and microwaves. The closer the infrared waves are to the microwave end of the electromagnetic spectrum, the more they are experienced as heat instead of light.
Infrared waves can increase the speed of growth for plant stems. A balance of red light and far infrared light can greatly increase the growth of internodes within the plant. Short exposure to infrared light alone will increase the growth while plain red light can reverse the effect. Plants that grow in light that is too red for too long will develop awkward stems that are both overly long and thin.
- Infrared light waves range between the light that humans can see unaided and microwaves.
- A balance of red light and far infrared light can greatly increase the growth of internodes within the plant.
Texas A&M University has stated that infrared light is important in the blooming of flowering plants. Plants will not bloom under ordinary fluorescent light that does not contain the proper levels of infrared radiation.
Infrared light waves are sometimes used to measure the growth of plants during experiments. By injecting a unique radioactive substance into the plant, scientists are able to analyze the cellular development of plants using infrared cameras.
Infrared light from the far, red end of the electromagnetic spectrum can damage plants. The heat from radiation can burn the plant cells, especially with plants that are dehydrated. Infrared light can also cause plants to flower and grow too early, forcing the plant to use too much energy before it has the necessary resources to maintain the growth.

Indoor gardening requires a balance of infrared light to properly aid in plant growth. Conventional bulbs sometimes provide the plant with too little or too much light, resulting in unhealthy plant development. Gardeners worried about a plant's lack of life can find specialized lights for proper infrared growth at local garden stores.

I was having problems with my home DSL gateway device a few months ago. It was an old-ish Netgear device which had been running fine for years. Since it supported only wireless A/B/G, I decided it was a good time to replace it for a wireless (draft) N compatible device as my latest laptop supported it.
After quickly looking at supported features of different brands on the market, I decided to go for one of those snazzy-looking “Linksys by Cisco” devices, the WAG160N : Four 100Mbps ports, ADSL2+ and Wifi N. Oh, what a huge mistake!
My thoughts on the Linksys WAG160N :
- Design, very sleek
- No power button
- No reset button
- No reset function from the management interface (!!)
- Heats a lot, left a mark where it was placed for a few months
- Wireless connection VERY flaky
- Wireless DHCP packets no longer working after a few minutes of uptime
It’s basically a pile of crap. The Linksys forums are plagued with complaints about the wireless not working very well, and the typical reply is “use a different wireless channel” (it does seem to help a bit to use channels which don’t overlap with many others, but doesn’t fix the underlying problems). I’ve patiently waited for a few months for a firmware update which would fix these problems, but it never came (still 1.00.15 as of writing this). After months of reaching for the power cable at the back of the device to unplug and replug it at least once a day, it gets… annoying.
So, screw Linksys, even “by Cisco”… actually, especially “by Cisco”, because lots of older Linksys models were amazingly good. I went out and bought the latest similar device by D-Link, the DSL-2740R, which seems to be the replacement of the older DSL-2740B : Same features, but different look and guts, supposedly performing better and slightly cheaper too. It cost me 80€ vs. 90€ for the DSL-2750B still on the shelves, which might be why D-Link doesn’t seem to have the DSL-2740R on many of their websites yet (only on the UK one as of last week).
Guess what? The D-Link device works like a charm. It’s actually amazing how well it works! Even when transferring huge files over wireless, the response time for the rest of the wireless connections stays good. I managed a sustained 10MB/s rsync over ssh transfer of a DVD image between my wireless-connected laptop and a desktop, which is a first for me with Wi-Fi.
My thoughts on the D-Link DSL-2740R :
- Works really well
- Has USEFUL features like static MAC to IP address mapping in its DHCP server
- Lacks USELESS bells and whistles, the management interface is slick and fast
- Nearly never requires a reboot when the configuration is changed
- Has a power button on the back
- Has a reset button on the back (plain power reset, in addition to the typical tiny factory reset)
- Has the default settings printed on the bottom (IP address and user/password… obvious, eh?)
- Stays at a reasonable temperature
- Has a telnet management interface (!)
- Very plain design… the Linksys looks much nicer, I’ve got to admit that
- No additional Wireless modes : Only AP, no bridge, client or repeater
For me the D-Link is a clear winner, by a huge gap.
Is is saddening that Linksys doesn’t seem to care much about its customers, since the WAG160N isn’t a new device at all, and has been causing problems since day one from what can be read in the Linksys forums. On the other hand, D-Link who already had what seemed like a very decent device (the DSL-2740B) released a great replacement. I know which brand I’ll be recommending for now.
An amusing yet frustrating point is seeing the contradiction in having the unreliable device not providing any easy means of restarting it, while the reliable one has three (power and reset buttons and remote admin reset). Go figure, though the correct design decision in my option is D-Link’s : You’re better safe than sorry. I’m now safe, but also sorry to have bought a WAG160N in the first place…

Bluetooth Dfu Image File: What It Is and Why You Need It
If you have a Bluetooth device that needs to be updated with new firmware, you may have heard of the term \"Bluetooth Dfu Image File\". But what does it mean and how does it work? In this article, we will explain what Bluetooth Dfu Image File is, how it is used for over-the-air (OTA) firmware upgrade, and what security features it offers.
Bluetooth Dfu Image File is a file format that contains the firmware image for a Bluetooth device. The firmware image is the software that runs on the device and controls its functionality. The file format is also known as GBL (Gecko Bootloader) format, as it is compatible with the Gecko Bootloader, a common bootloader for all Silicon Labs protocol stacks.
A Bluetooth Dfu Image File can be used to update the firmware of a Bluetooth device OTA, meaning that the device can receive the new firmware via a Bluetooth connection from another device, such as a smartphone or a PC. This eliminates the need for physical access to the device or a wired connection.
How is Bluetooth Dfu Image File used for OTA firmware upgrade?
To upload images OTA, you will need a dedicated Bluetooth application. You can either use Apploader or user application, as follows:
Apploader. The Apploader is a simple application, which is separated from the main application and has a minimal Bluetooth stack that handles the upload process. The Apploader can be used to update both the Bluetooth stack and the user application.
User application. The user application is the main application that provides the functionality of the device. The user application can be used to update only the user application itself, not the Bluetooth stack.
The OTA firmware upgrade process consists of the following steps:
The target device must be programmed with an appropriate Gecko Bootloader configuration and additionally with any Bluetooth application that supports OTA.
The target device must be rebooted into OTA DFU mode using the system_reset (1) API command.
The source device must have the new firmware image available in Bluetooth Dfu Image File format.
The source device must establish a Bluetooth connection with the target device and send the Bluetooth Dfu Image File using a custom protocol.
The target device must receive and verify the Bluetooth Dfu Image File and write it to its internal flash memory.
The target device must reboot and run the new firmware image.
What security features does Bluetooth Dfu Image File offer?
Bluetooth Dfu Image File offers three security features to protect against unauthorized or malicious firmware updates:
Authenticated (signed) upgrade file. An authenticated upgrade file means that an electronic signature is attached to the GBL file. The signature is produced with a public-private key pair. The public key is stored in the device, while the private key is kept secret by the manufacturer. The signature ensures that the upgrade file is from a trusted source.
Encrypted upgrade file. An encrypted upgrade file means that the content of the GBL file is encrypted to protect against eavesdroppers.
Secure Boot. Secure Boot means that a signature is attached to the firmware image (.s37) before it is packed into upgrade file formal (.gbl). A signed image file (secure boot) ensures that the image was not modified since last boot and that it is from a trusted source. This is checked at every boot.
How to create a Bluetooth Dfu Image File?
To create a Bluetooth Dfu Image File, you will need the following tools:
Simplicity Studio. This is the integrated development environment (IDE) for Silicon Labs products. You can download it from here.
Gecko Bootloader. This is the bootloader software that supports Bluetooth Dfu Image File format. You can find it in Simplicity Studio under Software Updates > SDKs > Gecko Platform.
Gecko SDK Suite. This is the software development kit (SDK) for Bluetooth applications. You can find it in Simplicity Studio under Software Updates > SDKs > Gecko SDK Suite.
Commander. This is a command-line tool for programming and debugging devices. You can find it in Simplicity Studio under Tools > Commander.
Private key. This is a secret key that is used to sign and encrypt the Bluetooth Dfu Image File. You can generate it using Commander or any other tool that supports ECDSA (Elliptic Curve Digital Signature Algorithm).
The steps to create a Bluetooth Dfu Image File are as follows:
Create a project for your Bluetooth application using Simplicity Studio and Gecko SDK Suite. You can use one of the example projects or start from scratch.
Build your project and generate a firmware image (.s37) file for your application.
Enable Secure Boot in your project by adding the following line to your project.xml (or project.bgproj) file: Then rebuild your project.
Create a project for your Gecko Bootloader using Simplicity Studio and Gecko Bootloader. You can use one of the predefined configurations or customize your own.
Build your project and generate a firmware image (.s37) file for your bootloader.
Create a Bluetooth Dfu Image File (.gbl) for your application using Commander. For example, you can use the following command: commander convert app.s37 --bootloader bootloader.s37 --keyfile private.pem --encrypt --sign --outfile app.gbl This command will convert the application image file (app.s37) into a Bluetooth Dfu Image File (app.gbl) using the bootloader image file (bootloader.s37) and the private key file (private.pem). It will also encrypt and sign the Bluetooth Dfu Image File with the private key.
You have now created a Bluetooth Dfu Image File that can be used for OTA firmware upgrade.
How to upload the Bluetooth Dfu Image File to the device?
To upload the Bluetooth Dfu Image File to the device, you will need the following tools:
A source device that has the Bluetooth Dfu Image File available and can send it over a Bluetooth connection. This can be a smartphone, a PC, or another Bluetooth device.
A target device that has the Gecko Bootloader and a Bluetooth application that supports OTA DFU. This can be either the Apploader or the user application.
A custom protocol that defines how the Bluetooth Dfu Image File is transferred and verified between the source and target devices. This protocol can be implemented using a custom GATT service and characteristics.
The steps to upload the Bluetooth Dfu Image File to the device are as follows:
Reset the target device into OTA DFU mode using the system_reset (1) API command. This will make the bootloader start either the Apploader or the user application, depending on which one supports OTA DFU.
Scan for and connect to the target device using the source device. The target device should advertise its OTA DFU capability using a custom service UUID.
Select the Bluetooth Dfu Image File on the source device and send it to the target device using a custom protocol. The protocol should use a control characteristic to initiate and terminate the transfer, and a data characteristic to send the GBL file.
The target device should receive and verify the Bluetooth Dfu Image File using the bootloader API. It should also decrypt and authenticate the GBL file if it is encrypted and signed.
The target device should write the new firmware image to its internal flash memory using the bootloader API. It should overwrite either the application area or a bootloader slot, depending on which part of the firmware is being updated.
The target device should reboot and run the new firmware image using the bootloader API.
What are the benefits of OTA DFU?
OTA DFU is a feature that provides many benefits for both the device manufacturers and the end users. Some of the benefits are:
Shorter time to market. OTA DFU allows you to launch your product before it is 100% finished, and then polish it on the field with updates. This gives you a competitive edge over your rivals who may spend more time on planning and testing.
Better customer satisfaction. OTA DFU enables you to fix bugs, address security vulnerabilities, and add new features to your product without requiring physical access or a wired connection. This improves the user experience and loyalty of your customers.
Adaptability to market changes. OTA DFU allows you to respond quickly to changes in the market, such as new standards, regulations, or customer demands. You can update your product to meet the new requirements and stay ahead of the curve.
OTA DFU is a powerful and essential feature for any Bluetooth device that aims to be reliable, secure, and future-proof. d282676c82


I discovered an unusual issue this week and was wondering if anyone else has seen this problem?
I have tested this on two 16" 2019 MacBook Pro's running Big Sur. If you run a speed test from https://www.speedtest.net or any other speedtest site in any web browser on Big Sur, the upload results are way, way off, typically the results show half to a third of the actual speed. The same test on MacBook Pro same model running Catalina and it returns accurate results. I tried SEVERAL different ethernet adapters and experienced the same results. I did notice Intel and M1 Mac Mini's with built in ethernet running Big Sur did not have this issue.
The Speedtest app from Ookla from the Mac App Store appears to return accurate results on MacBook Pro's running Big Sur with external ethernet adapters.
Earlier this week, our office upgraded our internet circuit and I "spent hours" trying to figure out why our speeds were so bad using speedtest.net which has always been relatively accurate. I assumed the problem was with the new ISP circuit or a QoS policy... I finally figured out it was any MacBook Pro using an external ethernet adapter and Big Sur. Ouch!!
Hope this helps someone before they fall into this trap.
Not seen this but one thing I did just notice something that may or may not be relevant. Do these machine also have an active wi-fi connection? If so does the speed get any better if you turn off wi-fi? Just looking at a different problem on a Big Sur machine where the primary network was wi-fi rather than ethernet and not sure speedtest asks or tells you which interface, does it?
I turned WiFi off for my tests to make sure it was not another variable. I only had one ethernet interface active. I ran the test with the following ethernet adapters plugged into the laptops Thunderbolt 3 port. OWC Thunderbolt 3 dock, Belkin USB-C to Gigabit adapter, Anker USB C tho ethernet adapter, Hyper Drive USB C to ethernet adapter.
All had the same incorrect speedtest results when using a web browser on Big Sur. All had different results ( what appeared more accurate results) when using the speetest app from the Apple App store.
Laptops running Catalina all gave correct results in the web browser using the same adapters.
Mac Mini's with built in ethernet did not appear to have any issues with Speedtest in a browser when running Big Sur.

Internet radio offers immense choice along with an array of other assorted advantages. The greatest strength of the internet radio is the availability of a variety of stations. It has extended his horizons from the basic genres. It also brings out the passionate hip-hop from the 1980’s. Internet radio also avails electronic music and video game soundtracks. It satisfies the taste of every individual through virtual streaming. The main advantage of the internet radio is that it runs very few commercials. On the other hand, the terrestrial radio station adds a lot of menace by streaming a steady range of commercials.
The internet radio stations run through the donations and subscriptions. They also play royalty free music. Hence these internet radio stations do not add to a load of commercial advertisements. The internet radio does not face any geographical limitations. It is available everywhere with an internet connection. A terrestrial radio station’s broadcast is always limited by geographical boundaries. A close proximity to the terrestrial radio station is required to listen to their broadcasts. Some of the broadcasts of the terrestrial radio station are also streamed online. The requisites for listening to internet radio remain unaffected right from its existence in the late 1990’s.
A computer with Windows, Mac OS or Linux version is the only requisites for listening to internet radio. With preinstalled software, music can be streamed online. In the meantime, more streaming radio stations are accessible through video game consoles and Smartphones. Dial-up modems avail lower-bandwidth Internet radio stations. The internet radio offers unsurpassed sound quality similar to that of a CD. While terrestrial radio stations lose a radio signal owing to interference and environmental causes, internet radio does not face problems of that sort. In the trending technological world, internet radio can thus be a right choice to explore.


1. What is EDDIE?
EDDIE is a tool that collects data from the system it is running on or from nearby systems or services. EDDIE can run rules over the collected data and take actions based on the results, making it a very useful system/service monitoring tool. EDDIE can also store the data somewhere, like a database, for future use in reporting or capacity planning, making it a very good data collection tool.
2. What data does EDDIE collect?
EDDIE can collect any data that it is setup to collect. Built-in to EDDIE, as of version 0.23, the following is collected:
3. What systems does EDDIE run on?
EDDIE currently runs on:
4. How difficult is it to port EDDIE to a new system?
System-dependent code is kept together in the lib directory. All Linux-dependent code is in lib/Linux and Solaris-dependent code is in lib/SunOS for example. Porting to a new system is simply a matter of porting the modules contained in these library directories. The bulk of the code, in lib/common, should run un-modified on all platforms.
5. How do I get EDDIE to store data into a database?
Storing EDDIE-collected data in a database requires a separate program called estored. This is the program which accepts data from EDDIE and inserts the data into the database. For EDDIE to communicate with estored the Elvin messaging system is required.

These “gold-plated” circuit boards were especially designed for Audible Illusions by John Curl using his proprietary technology.
When installed in the Modulus 3b Preamplifier they optimize the preamps standard phono stage for specific use with low-output moving coil cartridges. Overall phono-stage gain is increased to approximately 60dB of gain, enough to amplify M/C cartridges with outputs ranging from .1mV to .8mV.
Much improvement in M/C cartridge design has taken place during the past few years. High-quality moving coils are now wound under intense magnification using ultra-fine wire. This manufacturing process allows for coil mass to be less than half of what it was several years ago. There also has been considerable improvement in magnet design. The net result is improved voltage output from less mass which allows the styli to trace a records grooves much more accurately.
When coupled to the outstanding tube phono stage of the Modulus 3b, one can now hear the resolution of low-level-detail present in many analogue recordings. For the audiophile with a sophisticated audio system this technology brings a new dimension to the listening experience.


Devlog # 2: Docker Infrastructure
Due to digitization and the constant evolution of web technologies, the creation of a web infrastructure is increasingly complicated and, above all, complex. To be up-to-date (like complying with PSD2 regulations) it is necessary to add and combine applications from different providers, each with its own systems and programming languages. As you can imagine, the result is a complex ecosystem to maintain and coordinate. That is why we decided to implement a new infrastructure for Foxize Cloud: Docker.
How does Docker work?
Docker is an infrastructure system that allows you to organize your development environments. It is made up of independent containers, making it possible to have several environments available that can communicate with each other.
We could compare its structure with that of a Russian doll. Docker encapsulates specific functionalities, such as a Memcached server, which instead of having them configured in the container where the code is hosted (the largest Russian doll), is “externalized” in a container that is dedicated only to this functionality (the dolls that are inside). This allows access to the different functionalities without affecting the main code or vice versa, making maintenance much easier.
In addition, these containers make it possible to standardize the work area of the developers and allow easier access to the tools, regardless of the computer from which it is accessed.
What advantages does Docker bring us?
- It allows us to optimize the development infrastructure.
- Improves developer productivity.
- Putting it into action is much faster and more efficient.
- Speed in solving problems.
- We can scale projects more easily.
In short, having an infrastructure based on Docker, it is much easier to manage services.


Monitoring electrical consumption
Friday, May 30th, 2008 8:20AM UTC
Anyone who knows me knows I like stats, the more information the better. Like a doctor, I want to measure vital metrics and our managed VPS service is no different. We know exactly how busy a customer’s VPS is and by which computer metric (CPU, memory, disk, etc.) they are bound by. This makes it easy to know when a VPS needs to be upgraded (throw more hardware at it) or the customer needs to re-engineer their application to scale better.
On the personal front I’ve taken the initiative to monitor our power consumption, heating and cooling use. I wanted to start monitoring our electrical use house wide, something we’ve done for years with our data centers. Who doesn’t these days with many wanting to be environmental friendly and with rising fuel costs? While the Kill A Watt is a great meter, it can only monitor a device that’s plugged into its electrical outlet. At Empowering Media we use the Kill A Watt meter to monitor a server’s power consumption before it goes into production.
What I always wanted was a method to monitor power consumption for our entire house. I found out such a product exists and is called the PowerCost Monitor. I found out about it on an “old” “Ask this Old House” episode. Simply attach the remote sensor on to your electric company’s meter and the display updates every 15-30 seconds. The setup in my case, with an analog meter, took only 15 minutes. Best of all, is you can plug in your KwH rate(s) from your power company and will tell you how much power it’s costing you up to the min. This means no surprises at the end of the month. This product is also great to determine where the big suckers of electrical use come from. If your wife complains (sorry Jeanne) about how much it costs by leaving a light on in a room, now you will know.


Data and Information are power in the world we live in today. And if you can extract the best outcomes from it, you can accomplish the finest results for your business. This blog is going to take you into the world of that power & data and discuss its importance and how it is engineered for organizations to succeed.
What is Data Engineering?
Data engineering, often known as information engineering, is a software development technique for developing information systems.
To be clear, data engineering entails collecting, altering, and managing data from many systems.
This approach guarantees the data’s use and availability. Specifically, data engineering focuses on data gathering and processing practical applications. It should not be a surprise that complex methods are required to find the answers to the previous queries.
As a result, data engineering employs sophisticated techniques for gathering and verifying data, ranging from artificial intelligence to data integration technologies.
Similar to this, data engineering employs specialized techniques to adapt learned information to real-world circumstances. Typically, this requires planning and managing complex processing systems.
Why is it Important?
Data engineering is important because it allows businesses to improve data so that it is more usable. For instance, data engineering is crucial to the following projects:
- Determining the best strategies to improve your software development life cycle
- Improving data security and protecting your business from cyberattacks
- Increasing your business domain knowledge
- Combining data using tools for data integration and storing it in one place
Whether business teams are working with sales data or looking at their lead life cycles, data is available at every level.
The vitality of data has changed significantly through time as a result of technological innovation. These developments include big data expansion, cloud computing, and open-source projects.
The need for technical knowledge is emphasized in the final clause while discussing how to manage enormous amounts of data. The creation of comprehensive and coherent data is the aim of data engineers.
How Data Engineering Benefits Your Business?
Data engineering is, without a doubt, essential to digital automation and every company. Data engineering is key to your firm entity’s longer shelf life, from future analysis to current day-to-day operations. Data engineers are best qualified to tackle this activity even if you are able to record the daily inflow of data because they can make it understandable and coherent. Data engineering’s core need is that data must be understandable in order to be utilized. In fact, it has been shown that having access to and effectively using corporate intelligence can increase decision-making speed by up to five times.
Although the idea that data is valuable to a company may not be new, people rarely confuse its importance with other different employment roles.
Are you interested in data engineering? If you want to become one, then make sure to enroll yourself in a certification program because it’s tough for a data engineer without degree to land a job and have a bright future ahead.
Its Fundamental Concepts
- Fundamental difference: Data sets’ size
In general, a higher data set size is required for more information to be analyzed and processed. Consider huge firms like Google or Facebook, which frequently need powerful gear and complex algorithms to execute their internal tasks and analytics (for example: trending articles on Facebook or search results). Because of this, a lot of organizations employ a lot of data scientists to help them analyze the enormous amounts of structured and unstructured data they have.
- Data engineering is more technically oriented – Data science is more business-driven
The main difference between data science and data engineering is that the latter performs the following duties. At the same time, the former works with big, complicated, but relatively static datasets (which they typically only update very seldom). He or she looks over the most recent data available, looks for patterns within it, and uses this data to make business decisions based on in-the-moment awareness (and even predict future scenarios).
- Data engineering = ETL + ELT; Data science = ML + DL
ETL stands for extract, transform, and load. It involves taking data out of databases, modifying it to make it usable, and then loading it into the required storage (which can be another database or file system, for example). ELT stands for Extract, Load, and Transform. The steps for this method are the same as those for ETL, but once each stage is finished, you must load your updated dataset back into the original database (or file system). Machine learning (ML), a subtype of artificial intelligence, allows computers to learn automatically using certain algorithms to anticipate future events based on present data. Deep learning (DL), the cornerstone of machine learning, allows computers to learn independently by using artificial neural networks built on top of machine learning algorithms.
- While data engineering makes predictions, data science anticipates stock values.
You may have heard it frequently mentioned before, but data science is one of the fields with the quickest growth. This is true since it pertains to almost every profession (for example, finance or medicine). The advantage of data science over other professions is that it allows users to predict trends and base business decisions more on anticipated outcomes than actual experiences. If you’re thinking about a career in data science, look at this beginner’s visualization guidance. Review your skills utilizing our useful Python guide as well.
Data engineering makes it simpler to solve complicated business problems. If you want to thrive as a data engineer, head straight to Hero Vired’s website for a top data engineer certification course and equip yourself with the techniques and skills to become a certified data engineer.


Baofeng Programming Cable for BAOFENG UV-5R/5RA/5R Plus/5RE, UV3R Plus, BF-888S (Newest Version, Support WIN7,64 Bit)
on Amazon - It works!
The Baofeng UV5R is a wonderful little handheld, I have had it now for a couple of years, but have not really got the hang of programming it!
I have bought two different programming cables and neither of them worked, the computer didn't even recognise them. I spent many an hour trying different drivers and trying to get the beast going using CHIRP, but to no avail. I gave up!
When the cable and other items arrived - very quickly and delivered on a Sunday afternoon.
I cautiously connected the cable to the computer with Windows 7 expecting the usual 'Cannot recognise' message...but it didn't...it simply loaded the existing driver and said that it was ready for use. Next, I connected the Baofeng and started CHIRP to clone the radio...IT WORKED!
Amazing...at last I could program the radio with my computer. I then set about programming some channels into the memory. This is fine, but there is a problem with repeaters.
It seems that when you program the channels for repeaters the frequency shift for transmit / receive will not program on the Baofeng. You have to do it manually...what a pain!
Still, I now have a Baofeng UV5R that will program, I put in the repeaters manually after watching a tutorial on YouTube. Now I have a complete set of local repeaters programmed into the UV5R at last.


Code for scientific computation
I contribute to a few projects for scientific computation.
- Embodied Cognition Lab on Github
As we publish research we're doing at the Embodied Cognition Lab, we endeavour to make associated code available too. While this is often archived in a static form on the Open Science Framework, it is also hosted on Github, where it will continue to be developed.
One such project we have worked on is a systematic comparison of linguistic distributional models on a suite of cognitive science benchmark datasets.
Another is a computational cognitive model of associative activation underlying the category production task.
I also made the Sensorimotor Distance Calculator, a web app which allows calculations and visualisations of semantic distances between nearly 800 million pairs of concrete and abstract concepts, based on their sensorimotor experience profiles. This uses data from the Lancaster Sensorimotor Norms.
- The RSA toolbox
A Matlab toolbox for Representational Similarity Analysis on fMRI neuroimaging data. An EMEG extension is in the works.
This project is now managed by the RSA development group, and is being ported to Python as the pyrsa package: a project I am also involved with.
- Other projects on Github
Now and then when I make something generally useful for my work, I will put it up on Github.

High Quality, Best Service


How different is it to maintain electric construction equipment versus diesel construction equipment? The short answer is that with electric, it’s much simpler — hardly any maintenance is needed at all on the electric components. But if you’re looking for a little more detail, keep reading.
A major maintenance-related advantage of electric equipment is that the machines shut off when not in use, so they’re not racking up idle hours like a diesel machine that needs to keep fuel and fluids moving. As a bonus, fewer hours can help reduce your total cost of ownership and improve the resale value of the electric machine.
It follows, then, that DEF and filters aren’t needed on electric equipment. Essentially, the only supplies required are grease and hydraulic oil. This is much different than a conventional machine that requires fluid, filter and component checks as often as every day, with additional cyclical preventive fluid and filter maintenance.
ELECTRIC EQUIPMENT SAFETY AND TRAINING ARE KEY
Electric components like the lithium-ion battery, inverter, AC to DC power converter, battery management unit and charging plug just need visual and functional inspections. Any components not working would be replaced rather than repaired.
The electrical components are sealed and guarded, and technicians should be trained to properly disconnect the high-voltage power to any parts before they’re removed and replaced. Volvo CE, for example, has very stringent training and qualification requirements to certify technicians to work on electric machines, whether it be the electrical or non-electrical components.
Because we’re talking about machines using electricity, much of the additional training needed for technicians will be about safety. Some of the concepts they’ll need to learn include how an AC 3-phase motor functions, Ohm’s law (the relationship between voltage, current and resistance in a circuit), Fleming’s left- and right-hand motor and generator rules, and the effect that current flow has on a magnetic field. Other topics unique to electric heavy equipment are inverter function, onboard charging system operation and how a lithium-ion battery works.
This may sound like a big shift in what technicians need to know, but it’s part of our evolving industry. It’s just like when telematics and in-cab displays started becoming more prominent — technicians in the shop had to learn how to service those as well.
Charging systems may also need service at times. That would be dictated by the manufacturer of those items, which will typically be different from the machine manufacturer.
A VALUABLE SHIFT
The lifetime of battery-electric components should be equal to or better than that of the diesel engine on a conventional machine. We conservatively estimate that users will see a 35% savings in maintenance cost and time over the life of the machines we offer. And our six-year warranty for electric components provides some extra peace of mind.
Though the shift to electric requires some training, the overall maintenance needed for electric heavy equipment is much simpler and less frequent. With electrification expected to grow exponentially in the coming years, it’s a worthwhile investment of technicians’ time.

Zapraszamy na seminarium, które odbędzie się w dniu 23 marca 2022 r. (środa) o godz. 16.15 w sali A-1-08. Prelegent: Prof. Karol Lang, Department of Physics, University of Texas at Austin. Temat seminarium: „From anti-neutrinos to anti-electrons: PET research at the University of Texas at Austin”.
Research in fundamental experimental particle physics requires new experiments and novel detectors. Knowledge and experience gained in these endeavors can generate spinoffs that benefit fields outside of particle physics. In this talk, we will describe our work on building a time-of-flight positron-emission-tomography (PET) scanner for proton therapy at MD Anderson in Houston and some other related ideas towards improving and expanding the use of PET detectors.
Karol Lang is an experimental particle physicist and Jane and Roland Blumberg Professor of Physics at the University of Texas at Austin. He received his MSc. from the Warsaw University, and his Ph.D. from the University of Rochester participating in an experiment that searched for neutrino oscillations. As a postdoc, Lang worked at SLAC (Stanford) measuring the spin content of the nucleon and on an electron beam dump search for low-mass axions. He then worked at Stanford on a search for KL--> mu-e decays at BNL and a search for the H dibaryon. Lang joined the faculty at the University of Texas at Austin shortly before the Superconducting Super Collider (SSC) was cancelled in 1993. He is now involved in long baseline neutrino oscillations experiments and searches for neutrinoless double beta decay.

Rationale: It is worth mentioning from the start that this question is about high-level concepts of a new operating system, so a right answer should not include any implementation details. At the same time, most of the aspects related to performance should also be avoided when providing an answer. After all, performance is about engineering and the focus of this question should be on more general design principles, such as security or robustness.
First of all, a good question to ask the interviewer would be ‘What kind of operating system do these design requirements apply to?’. There are various classifications of operating systems. A first classification arises from the platform the operating system is written for. There are two main categories:
- Mobile operating systems – this is the kind of operating system that runs on mobile devices (mobile phones, tablets, other similar gadgets). The focus of such an operating system should be reducing power consumption, as most devices that will use it run on battery.
- Desktop operating systems – this is the operating system that runs on devices that are normally attached to a power source (desktop PCs, laptops). The focus of such an OS would be performance, rather than saving power.
- Single-tasking / Multi-tasking operating systems – single-tasking operating systems can only execute one program at a time, while a multi-tasking OS can run multiple programs at any given moment.
- Single-user / Multi-user operating system – single-user operating systems can be used by one user at a time, while a multi-use OS enables multiple connections to the same machine (for example, remote connections using the SSH command from other computers).
- Distributed / non-distributed operating systems – a distributed operating system manages a group of computers, rather than a single one, and makes these computers appear as a single more powerful machine. The advantage is that computations can be carried out on multiple computers at the same time.
Our model answer will focus on designing a single-user, multi-tasking, non-distributed operating system for desktop computers (PC, Mac, laptop). Here is a list of design principles you may wish to discuss with the interviewer when asked this question, along with some important points for each:
- Security – in terms of the security of a new operating system, perhaps the most important aspect to mention is that users should not have the right to access files that are not meant to be accessed by them. In this sense, the separation between processes that belong to the operation system (those initiated by system calls, for example) and those initiated by the action of users is crucial and should not be missed.
- Simplicity – the simplicity of an operating system is usually defined by how easy it is for the user to find exactly what they are looking for. An example is choosing the right name for file managers (‘My computer’ and ‘Computer’ are good examples that are already used by the world’s biggest OS manufacturers)
- Robustness – the design of an operating system is robust if the addition of new features does not cause any unexpected problems with the ones that are already implemented.
- Extensibility – Generally, an operating system that can be easily extended is regarded as a good operating system. Take, for example, Linux. The fact that made this operating system so popular is its customizability. Experienced users can build their own features or even write their own Linux distributions using the libraries provided.
- Uniformity – A uniform design for a new operating system is a design in which most components of the operating system are consistent. This may include choosing an appropriate color scheme and similar graphics for components with the same functionality.
- Predictability – This principle is about how easily a user can predict where bits of functionality of the operating system are located. For example, considering the trends that are already established, we can predict our users would expect to find the properties of a file by right-clicking on it.
- Reversibility – It may sometimes happen that the users of an operating system perform an operation that they want to cancel or undo. In this sense, a good design for a new operating system should be reversible, allowing this to happen easily.
- Support for multiple platforms – Last but not least, we live in a world where mobile platforms have become an absolute necessity. Therefore, any operating system that can be extended to such devices, or at least offer support for remotely logging in from these has a clear advantage.
To sum up, the key thing to remember is that open ended questions will always be open-ended and there are perhaps an infinite number of answers for them. As long as you keep asking questions and clearly establish the kind of operating system the interviewer is looking for, you will eventually be able to produce a good answer. Mobile operating systems differ greatly from desktop ones, for example, so it is important not to miss this step.

Green Mountain Power and Origin Consulting Successfully Upgrade Oracle MWM
Phase one of the MWM upgrade project consisted of upgrading MWM from version 2.2 to version 2.3. The latest major release of the Mobile Workforce Management application from Oracle offered highly anticipated new features and functionality.
For this phase of the project, Origin completed the development required to transition to the new Oracle mobile app for field crews, as well as the upgrade to service pack 2. GMP and Origin’s relationship has always been based on the foundation of collaboration. Collectively the team was able to deploy service pack 2 and complete user acceptance testing which culminated in a smooth and successful go live deployment.
As a result of moving to the Mobile Communication Platform (MCP), GMP is now able to run the Mobile Application natively on their iOS devices. This results in a reduction in overhead costs associated with virtual desktop solutions implemented to support the legacy version of MWM on mobile devices. In addition, GMP will solve a significant challenge of limited connectivity while in the field with the ability to work in offline mode using MCP. This will allow field workers to continue completing assigned work in MWM while working in rural areas with limited network coverage. Auto-syncing will then occur when field workers return to network access.
Shelly Hendee, Project Manager at GMP commented, “I just want to give a big Thanks you to EVERYONE – this was the smoothest, most efficient upgrade cutover I think I have ever experienced! This is pretty amazing with such a small team taking on such a big project.”


Developed for Cardiotech Australia this console housing provides a facelift to an existing vibrating fitness machine. A series of concept sketches were developed and presented to the client before the final design was achieved. The final design was then translated into 3D model for production. The 3D models were developed based on the dimensions of the electronic components inside the existing unit.
The new console makes use of illuminated buttons arranged in a very smart, simple and easy to understand layout. The new product was to be perceived as a hi quality product for the hi end market.


It appears that fiction can be a predictor of truth. Readers of the original "The Ladies Who Don't Lunch" might recall Lauren describing the work of a man named Thomas. Thomas talked about a concept he was working on to use electric cars to reduce dependency on gasoline. He explained how parking meters would be re-engineered to boost cars that needed more energy and to drain their energy for street lighting when the cars sat idle. Parking stalls in garages would have similar outlets, providing energy when the car was turned on and draining it from parked cars to light and heat the buildings above. In his system, energy was not stored in the vehicles, but drawn on when needed.
Today, CBC news reported on the concept as a reality. More electric vehicles are becoming capable of not only storing energy for driving, but also for powering buildings and the wider grid, thanks to a capability called "bidirectional charging." It's an emerging technology that could keep fridges, lights and the internet on in homes and other buildings during emergencies, eliminating or reducing the impact of most power outages. Bidirectional charging also has the potential to make the entire power grid greener and more efficient, enabling increased and better use of wind and solar power. Click here for a closer look at the technology.


Food for Thought
Asset Lifecycle Mgmt
For the last hundred years
hardware products have been built from interoperable components. This
approach has brought year-on-year cut in cost coupled with improvement in
functionality, performance, reliability and ease of use. Furthermore, if
we wanted to personalise the hardware product, we simply plug in optional
extras without even the need to read an instruction manual!
Imagine what difference would it make to cost, functionality, performance reliability and ease of use if software solutions too were also built from interoperable components!
This is exactly what the Datamation's universal Information Platform (uIP) was designed to deliver. The Datamation uIP brings to software solutions what manufacturing from interoperable components has brought to hardware products over the past hundred years.
The Datamation uIP also extends the concept of building from components to information assets. That is, instead of information assets being scattered over a plethora of disjointed systems, they are grouped as readily usable high integrity modules that form parts of consistent connected whole.
This opens numerous opportunities to deliver more value through reuse of data. Think of information as a business asset. Like any business asset, the more it is used, the more value it delivers. Specifically, the modular approach opens up the opportunity to support three of the fastest growth areas of Internet commence, namely Open Data, Internet of Things (IoT) and Big Data.

Israel Aerospace Industries (IAI) unveiled the Scorpius family of Electronic Warfare (EW) systems. Scorpius is the first electronic warfare (EW) system in the world capable of simultaneously targeting multiple threats, across frequencies and in different directions.
Scorpius is based on the Active Electronically Scanned Array (AESA) technology, which provides a breakthrough in EW performance – enabling a new generation of electronic warfare capabilities.
With AESA’s multi-beam capability, Scorpius can simultaneously scan the entire surrounding region for targets, and deploy narrowly focused beams to interfere with multiple threats across the electromagnetic spectrum. The system is able to target a range of threats, including UAVs, ships, missiles, communication links, low probability of interception (LPOI) radars, and more. Scorpius effectively disrupts the operation of their electromagnetic systems, including radar and electronic sensors, navigation, and data communications.
The new system’s technological breakthrough is characterized by unprecedented receiver sensitivity and transmission power (ERP), far exceeding those of legacy EW systems. This allows Scorpius to detect multiple threats, of different kinds, simultaneously, from dramatically increased distances, and to address each threat with a customized response.
The system is available across multiple domains:
- Ground: Scorpius-G (ground) is a ground-based EW system designed to detect and disrupt ground- and airborne threats. Scorpius-G is a mobile system, and can be quickly deployed by vehicle. Scorpius G represents a new category of air defense systems: “Soft-kill” air defense, which creates an electronic dome of protection above a wide geographic sector to neutralize a broad range of modern threats.
- Naval: Scorpius-N (naval) is an EW system dedicated to defending ships against advanced threats in the marine arena, including: Over-the-Horizon Anti-Ship Cruise Missiles, Unmanned Combat Aerial Vehicles (UCAV) and airborne imaging radars. Scorpius’ extremely high range provides early detection and targeting of threats, which is essential for effective protection in the naval domain.
- Air: Scorpius SP, a self-protection pod for combat aircraft, and the Scorpius SJ, a standoff jammer that disrupts enemy aerial and ground-based electromagnetic operations across a vast sector.
- Training: Scorpius-T (training), unveiled last month, provides EW training for pilots. Scorpius-T can emulate a variety of modern air-defense systems, simultaneously, from a single platform. Its advanced emulation capabilities support training for fifth-generation aircraft. Scorpius T made its debut during the international air force exercise Blue Flag 2021.
Adi Dulberg, General Manager, Intelligence Division, IAI: “The modern battlefield depends on the electromagnetic domain for sensing, communications, and navigation. Protecting the use of the electromagnetic domain for our forces, while denying its use by the enemy, has become mission-critical for success in combat and for ensuring the superiority of our forces in the field. The new technology, developed by IAI’s talented engineers, tips the scale of electronic warfare, providing world-first breakthrough capabilities for electronic defense and disrupting enemy systems”.
Scorpius-N (ELL-8256SB) is a powerful shipborne, long-distance RF Electronic Countermeasures (ECM) jamming system for accurate multi-beam, multi-technique electronic attacks. Scorpius-N can effectively jam a wide variety of airborne and shipborne systems and anti-ship missiles, such as fire control radars, search radars, AEW sensors, communication emitters, SAR, and other intelligence sensors.
The system is based on advanced and innovative technology featuring Active Electronically Scanned Array (AESA) with Gallium-Nitride (GaN) Solid State Amplifiers (SSA). The novel design provides exceptional receiver sensitivity and Effective Radiated Power (ERP) transmission, far exceeding those of legacy EW solutions. The enhanced sensitivity and ERP enable Scorpius-N to detect, distort and degrade enemy radars through their side lobes, greatly increasing the system’s jamming effectiveness.
The AESA technology allows for narrow, simultaneous multi-beam operation. Multi-beam forming provides the ability to target multiple threats individually. The system can simultaneously jam numerous emitters over its entire frequency range while covering a wide geographic sector. The system continuously intercepts, tracks, and jams all types of radars, missile seekers and communication systems and displays an Electronic Order of Battle (EOB). The jammer is driven by a pre-programmed Mission Defined File (MDF) and can operate automatically or under direct operator control.
Scorpius-N comprises four conformally-mounted panels on the central mast. The system operates independently or networked with other vessels providing enhanced ECM capabilities.
The system comprises a Set of Transceivers covering a wide frequency range, Control Unit for processing and controlling all ECM operation, and Operator Console for mission planning, maintenance, training, analysis, and debriefing.
