What is SSH Tunneling? or What is Port Forwarding vis SSH? System admins can use this machine to connect to other instances in the backend infrastructure via secure authentication mechanisms. This is usually a powerful server box with high network security as this is the only host which is allowed public access. The other common name used for a bastion host is ‘Jump Box’. In very simple terms, a bastion host is the only host or computer which is allowed public network access. In this post, I will go over some basics and show how you can access your backend infrastructure by SSH tunneling through a bastion host. Using a bastion host in such cases comes very handy, and is used very frequently. The AWS Shared Responsibility model requires you as a user to ensure that your resources and data are secure. A public cloud environment is different than a normal On-Prem environment as it has a greater possibility of getting hacked since it does not sit behind an IT-controlled firewall like in most corporate data centers. The database access should be limited to the developers and the instance level access only to the Administrators. ![]() At network or VPC level, you should consider a tiered approach wherein only the application layer or web UI console is accessible to the customers. To achieve that in AWS, you can use hardened AMIs allowing only controlled access at the OS and application level. ![]() In real scenarios of cloud deployment, it is recommended to secure the infrastructure with tight network security.

![]() The Acton Blink S wheels are designed to halt after a few inches, making it highly safe for you. The average distance covered by the skateboard on the application of brake before coming to standstill determines the safety factor for the rider. They are integrated with the regenerative braking to halt within seconds after you apply it. The core of every wheel is designed to get perfect grip on the road and reach top RPM with little resistance. The assembly components like the bearing, axle, and the nut can withstand high volume of friction and stress from the wheels and the board weight to keep the wheel perfectly in position. The designers of the Acton Blink S have taken special care to reverse this trend, by incorporating few innovative design aspects for the wheels. Generally, the payload weight and the speed are in inverse proportions for the standard skateboards you find in the market. With a diameter of 80mm and hardness factor of 78a, the Acton Blink S wheels can at the top speed and carry maximum payload. They are made of Polyurethane compound material to provide high load bearing capacity. Integrated Wheels: The integrated wheel design of the Acton Blink S makes them work at highest efficiency in all road conditions.The long running durability of the truck is largely due to the optimum hanger with and the axle width. The Acton Blink S kingpin design makes the device light weight and strong in nature. The bushing absorbs maximum shocks emanating from the wheels and protects the motor. This device is capable of navigating the Acton Blink S through flat roads, inclined roads, and rugged terrains with ease. Master Truck: The master truck in the Acton Blink S has a string base plate, shockproof bushing, safety kingpin and perfectly wide axle and hanger.The Acton Blink S deck goes through perfect processes of graining, leveling, shaping, contouring, gluing, and pressing to make it perfect in all practical aspects. The concavity of the nose and the tail determines the speed and effectiveness of the skateboard. The manufacturers have included the warp proof property for the wood, which is induced during the process of manufacturing and pressing. The material has high tensile strength, enhanced flexural strength and rider weight capacity of 235LBs at top speed and efficiency. Board Deck: The Acton Blink S deck is made from the composite light weight wood.You can experience the best performance in all the three modes of action for the beginner, standard and the pro. The Acton Blink S motor converts the battery supplies into maximum power and pushes the Acton Blink S board ahead on its path. The motor is built into the urethane coated wheel and surrounded by power packed magnets. The acceleration is achieved with the help of a power packed motor shell, backed by a bearing, and washer. Hub Motor: The single hub Acton Blink S motor is designed for optimized performance to push the speed from 0 to 15mph within a span of few seconds. ![]() Every part works in seamless integration with the others to deliver highest performance and speed within the shortest time interval after start up. The integrated design of the Acton Blink S includes single hub motor, strong wheels, regenerative brake, strong truck, efficient battery, and high Flexural strength of the board.

I shoot about 70% wildlife /action type environments and 30% macro/landscape. If you NEED usable high ISO, high frame rate with ample buffer the D5 is a no brainer. If I had never seen the image quality of the D810 or D850 the decision would be simple.D5. First impression is that the D850 is very impressive. I have owned and shot both but I haven't spent enough time with the D850 to make a fully educated evaluation yet.I was fortunate enough to get the camera but cant get my hands on a battery grip as of yet. Right now I am putting more of my money into faster lenses and running the D850 for is a calculated compromise in a lot of aspects over the D5. In an ideal world the D5 and D850 would both stay in my bag. For everything else, it’s the D850 hands down. For wildlife and kids sports, as also low light stuff, I would still prefer the D5. As you wrote, they serve difference purposes. Thankfully, I don’t have to make that choice, so keeping both. I am a hobbyist, and if pushed to make a choice, I would keep the D850. Hi - I have both the bodies, have never used a D8** Camera before I got the D850, and have to admit I have been blown away. I burrowed 120-300/2.8 sport version to try with my D850 briefly.

Both albums were successful in Puerto Rico, but not throughout Latin America. He released two compilation albums with original material: El Cartel (1997) and El Cartel II (2001). In 1997, Daddy Yankee collaborated with the rapper Nas, who was an inspiration for Ayala, in the song "The Profecy", for the album Boricua Guerrero. DJ Playero and Daddy Yankee would later be credited for inventing the name "reggaeton" to describe their music on the album Playero 36 in 1994. Throughout the 1990s, Daddy Yankee appeared in several of DJ Playero's underground mixtapes which were banned by the Puerto Rican government due to explicit lyrics these songs would later be among the first reggaeton songs ever produced. In doing so, he eventually abandoned the traditional model of rap and became one of the first artists to perform reggaeton. He went on to emulate other artists in the genre, including DJ Playero, DJ Nelson, and Tempo taking elements from their styles in order to develop an original style with the Dembow rhythm. ![]() Early in his career he attempted to imitate the rap style of Vico C. His first official studio project as a solo artist was No Mercy, which was released on Apthrough White Lion Records and BM Records in Puerto Rico. He first appeared on the 1994 DJ Playero's Mixtape, Playero 34, with the song "So' Persigueme, No Te Detengas". The bullet was never removed and he credits this incident with allowing him to pursue a musical career. Often considered to be one of the pioneers within the reggaeton genre, Ayala was originally going to become a professional baseball player but he was shot in the leg while taking a break from a studio recording session. Musical career 1994–1999: Career beginnings 1.7 2016–2022: Continued success, "Despacito", Legendaddy and retirement.1.4 2007–2009: El Cartel: The Big Boss and Talento De Barrio.He was named by CNN as the "Most Influential Hispanic Artist" of 2009, and included in Time 100 in 2006. He also received a Puerto Rican Walk of Fame star, special awards by People en Español magazine, and the Presencia Latina at Harvard University. He has won five Latin Grammy Awards, two Billboard Music Awards, 14 Billboard Latin Music Awards, two Latin American Music Awards, eight Lo Nuestro Awards, an MTV Video Music Award, and six ASCAP Awards. Īs of March 2022, Daddy Yankee has won 184 awards from 484 nominations (see List of awards and nominations received by Daddy Yankee). In March 2022, Daddy Yankee announced that he would be retiring from music after the release of his upcoming seventh studio album Legendaddy and its supporting tour. ![]() Its success led Daddy Yankee to become the most-listened artist worldwide on the streaming service Spotify in June 2017, the first Latin artist to do so. The video for "Despacito" on YouTube received its billionth view on April 20, 2017, and became the most-watched video on the platform. It became the first Spanish-language song to hit number one on the Billboard Hot 100 since " Macarena" in 1996. In 2017, Daddy Yankee, in collaboration with Latin pop singer Luis Fonsi, released the hit single " Despacito". Daddy Yankee's album Barrio Fino made history when it became the top-selling Latin music album of the decade between 20. Since then, he has sold around 30 million records, making him one of the best-selling Latin music artists. In 2004, Daddy Yankee released his international hit single " Gasolina", which is credited with introducing reggaeton to audiences worldwide, and making the music genre a global phenomenon. Ayala spent roughly a year and a half recovering from the wound the bullet was never removed from his hip, and he credits the shooting incident with allowing him to focus entirely on a music career. Before he could be officially signed, he was hit by a stray round from an AK-47 rifle while taking a break from a studio recording session with reggaeton artist DJ Playero. He aspired to be a professional baseball player and tried out for the Seattle Mariners of Major League Baseball. He is often cited as an influence by other Hispanic urban performers.Īyala was born in Río Piedras and was raised in the Villa Kennedy Housing Projects neighborhood. Known as the " King of Reggaetón" by music critics and fans alike, he is the artist who coined the word reggaeton in 1994 to describe the new music genre that was emerging from Puerto Rico that synthesized American hip-hop, Hispanic Caribbean music, and Jamaican reggae rhythms with Spanish rapping and singing. Ramón Luis Ayala Rodríguez (born February 3, 1976), known professionally as Daddy Yankee, is a Puerto Rican rapper, singer, composer, and actor. ![]() Violins rest underneath a person’s chin with support by the shoulder. Violins often have four strings tuned in perfect fifths. Sometimes called a fiddle, a violin often comprises wood with a hollowed out chamber for the body. They require the use of a bow along with finger picking to produce sound. However, violins are part of their own instrument family and are the smallest instrument with the highest pitch. ![]() ViolinĪnother eight-shaped instrument, violins share similar characteristics to but are much smaller than acoustic guitars. What makes electric guitars different is their application of magnetic pickups that converts vibration into an electric signal that travels through an amplifier. They have varying thicknesses to produce different sounding notes.Īcoustics are often hollow and wooden where as electric guitars are solid wood. Whether acoustic or electric, the strings are the same length and made of metal or nylon. There are two kinds of guitars that provide sound from their body: an acoustic resonant chamber or amplification by electronic means. The plucking or strumming comes from the dominant hand while the opposite hand presses down the frets and strings on its neck. GuitarĪ guitar is a stringed instrument from the Lute family shaped like a figure eight. Tuning is the act of loosening or tightening strings to the proper notes for optimal sound. For an instrument to play well and according to standard notes, it must undergo tuning. They have strings that affix to opposing ends of the instrument across a flat face. String instruments come in classifications of families, with the most common being the Lute, Violin and Lyre. The body is an enclosed or hollowed chamber made of a material that will resonate to produce a unique sound for each individual instrument. Thick strings will sound very deep compared to those that are thinner, where the sound is tiny and high.Īn instrument’s body size, structure and material also affect the quality, volume and projection of sound. Tighter, shorter strings create quicker, higher pitched tones while longer, looser strings create lower, drawn-out ones. How Strings & Body Affect SoundĪ string’s length, thickness and tension are what produce various tones from the instrument. Here the sound also vibrates and resonates with the air inside. Upon manipulation of the string, the vibration transfers into the body of the instrument. The manipulation, or bending and pressing, or the strings furthers the sound by elongating or shortening the effect. But, things like bows, allow for a very long and sustained vibration with a beautiful dynamic not easily created with other implements.Ī musician can play strings individually, indicating one note succeeded by another, or strum together to produce multiple simultaneous sounds in a chord. Picks, plectrums, fingers and hammer-like objects make a single, brief sound. This excitation happens when a person uses a pick, plectrum, bow, their fingers or some other implement to strike a string or to strum several strings.Įach implement creates a different effect on the vibration produced. To play a note of music is the act of exciting vibrations from different strings. The combination of materials that comprise an instrument is what delivers the sound unique to each. The sounds, or notes, culminate in a musical composition by their arrangement and artistic execution. String instruments, or chordophones, are musical devices that create sound by exciting the strings. How String Instruments Work & Produce Sound The following guide will help you understand some of the different types of string instruments that exist, where they come from and what they sound like. Stringed instruments are one of the most popular choices for musicians because they can produce sound with great clarity. In this guide you will learn how strings instruments work, the different types as well as a complete list of string instruments.

The main challenge of image steganography is to keep the basic properties and visuals of the carrier image unaltered. The main focus is to preserve the integrity of the message to be transmitted. However, beside these misuses of steganography, it is also used widely in many fields such as biometrics- to match and hide fingerprints in respective identity cards of the employees, in digital watermarking, in military applications to transmit information during wartime, etc. The photograph appeared completely normal to the naked eye initially. Later, on analyzing it completely, it was discovered to have some messages embedded in it. In 2011 Mumbai blasts, terrorists used an old photograph of a known Indian actress to hide important information. The recipient has access to various steganography softwares or trained networks to extract the desired message. Secret messages, codes are embedded in cover media and posted on public sites. Terrorists use this technique to communicate among themselves without getting caught by the military. Steganographic techniques have been used as a medium to hide information since long. If that embedded secret message is retrieved from the stego object, it is said to be active steganalysis. On investigating the stego object, if only the absence or presence of secret message is detected, it is passive. Steganalysis can be of two types-passive and active. The more similarity, the better is the steganography. It may or may not be similar to the original media. On applying the steganographic operations on the original media, a stego object is created. Both processes can be done on many different types of digital media such as image file, text messages, audio files, video messages etc. These hidden messages done using steganography are revealed by steganalysis. The minute differences within the pixels of the quilt media from the initial media are not noticeable to the human eye when transmitted through a carrier. The steganography process exploits the properties of the human eye. The goal of modern steganography is to securely transmit a digital message embedding it in a cover media. On observing the quilt media, one cannot work out if there is presence of any secret message embedded in it whereas in cryptography, the transmitted message over a channel is encrypted with a key and on observing it, it is known that the message is encrypted or not. It is the strategy used for concealment or hiding of a message in another cover media. The term steganography was coined centuries ago when messages were physically hidden. Secure transmission of messages is done using various cryptography and encryption techniques. Thus, this work has wide and secure applications in many fields. The network is only trained once, irrespective of the different container images and secret messages given as inputs. Also, other steganography softwares cannot be used to reveal the message since the model is trained using a deep learning algorithm which complicates its steganalysis. ![]() The main aspect of this work is it produces minimal distortion to the secret message. The decoder network on the receiving side, which is simultaneously trained with the encoder, reveals the secret image. The encoder neural network determines where and how to place the message, dispersing it throughout the bits of cover image. In this project, along with LSB encoding, deep learning modules using the Adam algorithm are used to train the model that comprises a hiding network and a reveal network. The cover image also called the carrier can be publicly visible. An N * N RGB pixel secret message (either text or image) is to be transmitted in another N * N RGB container image with minimum changes in its contents. The goal in our project is to hide digital messages using modern steganography techniques. Steganography has been used since centuries for concealment of messages in a cover media where messages were physically hidden. |
