Here is a simple Map implementation that will work with any type of key, including object references, and it will not mutate the key in any way: function Map() { var keys = [], values = []; return { put: function (key, value) { var index = keys.indexOf(key); if(index == -1) { keys.push(key); values.push(value); } … Read more
I used following steps to generate a Key Hash for my app in facebook: (I am using Mac OSX 10.8) First open a terminal (open a command prompt in windows). Navigate in the terminal to the directory where your Android debug.keystore is stored. Mostly it will located under “/Users/user_name/.android/” (In Windows will be C:\Documents and … Read more
You can use a third party utility called rlwrap. rlwrap is a readline wrapper, a small utility that uses the GNU readline library to allow the editing of keyboard input for any other command. It maintains a separate input history for each command, and can TAB-expand words using all previously seen words and/or a user-specified … Read more
A slight revision of @fivetenwill’s answer, which works for me on Spring Boot 1.4.3.RELEASE: foo: “[bar.com]”: a: b “[baz.com]”: a: c You need the brackets to be inside quotes, otherwise the YAML parser basically discards them before they get to Spring, and they don’t make it into the property name.
ar = [{“Vegetable”=>10}, {“Vegetable”=>5}, {“Dry Goods”=>3}, {“Dry Goods”=>2}] p ar.inject{|memo, el| memo.merge( el ){|k, old_v, new_v| old_v + new_v}} #=> {“Vegetable”=>15, “Dry Goods”=>5} Hash.merge with a block runs the block when it finds a duplicate; inject without a initial memo treats the first element of the array as memo, which is fine here.
The size of a RSA key is expressed in bits, not bytes. 2048 bits are 256 bytes. A bare-bone RSA private key consists in two integers, the modulus (a big composite integer, its length in bits is the “RSA key length”) and the private exponent (another big integer, which normally has the same size than … Read more
Here I copy paste some of the information that I have collected Key A key is a single or combination of multiple fields. Its purpose is to access or retrieve data rows from table according to the requirement. The keys are defined in tables to access or sequence the stored data quickly and smoothly. They … Read more
It’s as simple as this : $array[$key];
Solution: The KeyStore password and The Key password should be the same. Changing both passwords using keytool Change KeyStore password keytool -storepasswd -new %newpassword% -keystore %YourKeyStore%.jks replace %newpassword% with your actual password, same with YourKeyStore Change Alias key Password keytool -keypasswd -alias %MyKeyAlias% -new %newpassword% -keystore KeyStore.jks Note: supply old passwords for both keystore and … Read more
