Hello, today I was surfing on internet and saw a webpage which about e-mail security tweaks and test tools. Many times, I do not believe the tools that says "increase your protection". This one is different because MECSA tool was designed by JRC and this tool was published by europe union. (JRC means joint research centre)
MECSA E-mail Security Checker: https://mecsa.jrc.ec.europa.eu/
EU Describe this tool;
MECSA is an online tool developed by the Joint Research Centre (JRC) to assess the security of email communication between providers.
By following a simple procedure, MECSA will allow you to better understand the technical capacity of your email provider to protect the security and privacy of your email communications.
How to mine Zcash via CUDA?
Hello, In this article I’ll mention about mining, zcash and mining programs. Nowadays, crypto currency is becoming very popular and many people invest their money in this field. Day by day bitcoin and other popular (zcash, etherium) coin’s prices becoming very high. To mine Zcash and make profit, you should have a wallet of zcash and zcash mining program.
If programs cannot run properly, you update your nvidia drivers and you should install CUDA libraries. Do not forget many miner problems are caused by missing library files.
Nvidia Driver Update link: http://www.nvidia.com/Download/index.aspx
CUDA Download Link: https://developer.nvidia.com/cuda-downloads
You can mine yourself or participate a pool that includes people who want to mine zcash like you.
Wallet Program: Jaxx
Pool Example: https://zec.nanopool.com
Program: EWBF'S ZCASH Miner 0.3.4b / zm-0.5.7 miner (You can download these programs in the pool website, and you should configure the program with your wallet number and miner name.
CUDA = Compute Unified Device Architecture
CUDA is a technology, feature, parallel computing platform and API that created by NVIDIA engineers. It also addition of C language. Also, the CUDA platform is designed to work with programming languages such as C, C++, and Fortran. This accessibility makes it easier for specialists in parallel programming to use GPU resources. That's why cuda is becoming so popular. On the other hand, to write OpenGL or Direct3D programs that required advanced skills in graphics programming. With cuda technology, we can make more efficient use of the GPU cores and use the cores in the GPU based process.
As we know, In computer games or that industry GPU's are very important for fps and quality. Day by day the industry use new technologies and games wants much more graphics power to run games properly. GPU's main purposes of games are graphics rendering and physical calculations (PhysX).
CUDA has also been used to accelerate non-graphical applications in computational biology, cryptography and other fields by an order of magnitude or more. This field very important because of MINING. Zcash and Etherium is very important and to produce these coins, we use our gpu power. Especially to mine zcash, CUDA technology uses very much.
Nowadays, many Nvidia gpu's support cuda features and technologies. No doubt that, many cuda versions are available and their performance different from each other.
What is circuit breaker mean ?
Circuit breaker is a device designed to shut off an electrical circuit when too much current is flowing. This usually occurs if too many devices are plugged in or if there is a short circuit. Circuit breakers are usually installed in the electrical panel. Inside the circuit breaker, there is usually two contacts which is touched between. When detect a fault in the system, poles are divided each other. The system reacts to immediate short circuits. The process can be change different circuit breaker types.
TypesThe types of circuit breakers can be divided by these fields;
By voltage level
Low voltage circuit breakersCommon in domestic, small industrial and commercial applications include Miniature circuit breaker (type B, type C and type D)and Molded Case Circuit Breaker versions.Characteristics given by international standards.Also It is made for DC applications.
Oil circuit breaker
Common in domestic, small industrial and commercial applications include Miniature circuit breaker (type B, type C and type D)and Molded Case Circuit Breaker versions. Characteristics given by international standards. Also It is made for DC applications.
SF6 Gas circuit breakerIn this type of circuit breaker, the contacts of device surrounded by SF6
They are most often used for high voltage transmission-level voltages. Especially cold places heating might be require to prevent gas liquefaction.
Disconnecting circuit breaker (DCB)
The disconnecting circuit breaker (DCB) was introduced in 2000 and is a high-voltage circuit breaker modeled after the SF6-breaker. The DCB is also high voltage circuit breaker.
The type of circuit breaker reduces the space requirement, increases availability and reliability.
Vacuum Circuit BreakerIn this circuit breaker, the fixed and moving contact is enclosed in a permanently vacuum area.Vacuum circuit breaker has a high insulating medium for arc extinction as compared to the other circuit breaker.
When the fault occurs in the system, the contacts of the breaker are moved apart and hence the arc is developed between them.
Carbon dioxide (CO2) high-voltage circuit breakersWorks on the same principle as Sulphurre hexafluoride circuit breaker, can also be produced as a disconnecting circuit breakers, high voltage breakerPossible to reduce nearly 10 tons of carbon dioxide emissions during the product’s life time .
ConclusionCircuit breaker is an essential part of electrical network as it protects every device from electrical damage. Helps us to detect the fault and the area associated with it. Day by day circuit breaker technology is increasing and new techniques invent. So, the circuit breakers becoming safer than older types. Nowadays, most common circuit breake types are vacuum and sulphur hexaflouride circuit breakers are widely used due to their reliable and fast operations.
