A blockchain hasthree central attributes: First, a blockchain database must be cryptographically secure. That means you need two cryptographic keys to access or add data on the database: a public key, which is basically the address in the database, and the private key, which is an individu...
In a private, permissioned blockchain, such as multichain, every node might be able to perform transactions, but participation in the consensus process is restricted to a limited number of approved nodes. Public blockchain. Public, or permissionless, blockchains don't require permission to enter ...
RAID 1.Also known asdisk mirroring, this configuration consists of at least two drives that duplicate the storage of data. There is no striping. Read performance is improved since either disk can be read at the same time. Write performance is the same as that of single-disk storage. RAID ...
An exception to that would be if the virtual disks are backed by high speed NVMe or NVDIMM technology within the hypervisorandthe guest is performing a very large number of I/O per second along with small I/O sizes (4kb). In this corner case, then switching to thenonescheduler can provi...
*A headless browser is a type of web browser, much like Chrome or Firefox, but it doesn’t have a visual user interface by default, allowing it to move much faster than a typical web browser. By essentially running at the level of a command line, a headless browser is able to avoid ...

Network-wide Security Situational Awareness HiSec Insight dynamically integrates information about attacks, threats, vulnerabilities, an...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
The following rules are for reference. Adhere to the command line syntax when configuring ACL rules. rule permit xxx/rule permit xxxx: allows the specified packets to pass. xxx/xxxx indicates packet attributes, such as source IP address, source MAC address, and time range. The range xxxx invo...
If the ReadyNodeTM is listed 512e and swapped with 512n, you are expected to have better performance based on your workload. However, you may experience, especially with small block size workload, performance degradation when 512n is swapped with 512e HDD drives. Q:- What is vSAN Secure...
