There are very good configurations to force typings and get more helpful errors which are not activated by default. { "compilerOptions": { "alwaysStrict": true, // Parse in strict mode and emit "use strict" for each source file. // If you have wrong c...

Sql Server 2016+ and Azure Sql database enables you to automatically filter rows that are returned in select statement using some predicate. This feature is called Row-level security. First, you need a table-valued function that contains some predicate that describes what it the condition that will...

Security policy is a group of predicates associated to tables that can be managed together. You can add, or remove predicates or turn on/off entire policy. You can add more predicates on tables in the existing security policy. ALTER SECURITY POLICY dbo.CompanyAccessPolicy ADD FILTER PREDICATE...

Random mask will show a rundom number from the specified range instead of the actual value: ALTER TABLE Product ALTER COLUMN Price ADD MASKED WITH (FUNCTION = 'random(100,200)') Note that is some cases displayed value might match actual value in column (if randomly selected number matches valu...

Password Based Key Derivation can be used both for deriving an encryption key from password text and saving a password for authentication purposes. There are several hash algorithms that can be used including SHA1, SHA256, SHA512 which are provided by this example code. The rounds parameter is use...

See Swift 3 example for usage information and notes func pbkdf2SHA1(password: String, salt: [UInt8], keyCount: Int, rounds: Int) -> [UInt8]? { return pbkdf2(CCPBKDFAlgorithm(kCCPRFHmacAlgSHA1), password:password, salt:salt, keyCount:keyCount, rounds:UInt32(rounds)) } func pbkdf2SHA256(p...

We initialize the data we want to interpolate: x = 0:0.5:10; y = sin(x/2); This means the underlying function for the data in the interval [0,10] is sinusoidal. Now the coefficients of the approximating polynómials are being calculated: p1 = polyfit(x,y,1); p2 = polyfit(x,y,2); p3 = polyfit(...

I would venture to say that 80% of the processing that goes on in modern computing systems does not require user interaction, such as kernel code for Linux, OSX and Windows. For those that do, there are two fundamentals which are interactivity via keyboard (pointing devices) and console. This exampl...

Determine the number of PRF rounds to use for a specific delay on the current platform. Several parameters are defaulted to representative values that should not materially affect the round count. password Sample password. salt Sample salt. msec Targeted duration we want to achieve f...

Go to the directory with the source code: cd freebsdsrc Go to the directory with the kernel's configuration code: # If your system is 32-bit. cd sys/i386/conf/ # If your system is 64-bit. cd sys/amd64/conf/ Get a copy of the GENERIC kernel (let's call it MODEDKERNEL). It will ...
