JQ to filter JSON by value

JQ to filter JSON by value

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

spacemacs - global search and replace

There's a couple of ways, one way is

  • Get search results
    • Do SPC / and type in your search string
    • or SPC x S and search string - where x is your scope indicator (p for project, d for directory, etc..)
  • Once you have the occurences you want, hit C-c C-e inside the helm buffer to put all your match occurences and puts them into a special buffer called the edit buffer or something like that
  • in that buffer you can use any commands you'd normally use on a buffer
  • the C-c C-c to commit your changes.

Recursion and Trampolines in Scala

Recursion and Trampolines in Scala

Recursion is beautiful. As an example, let's consider this perfectly acceptable example of defining the functions even and odd in Scala, whose semantics you can guess:

def even(i: Int): Boolean = i match {
  case 0 => true
  case _ => odd(i - 1)
}

def odd(i: Int): Boolean = i match {

Processing errors with Fetch API

I really liked @tjvantoll article Handling Failed HTTP Responses With fetch(). The one thing I found annoying with it, though, is that response.statusText always returns the generic error message associated with the error code. Most APIs, however, will generally return some kind of useful, more human friendly message in the body.

Here's a modification that will capture this message. The key is that rather than throwing an error, you just throw the response and then process it in the catch block to extract the message in the body:

fetch("/api/foo")
  .then( response => {
    if (!response.ok) { throw response }
    return response.json()  //we only get here if there is no error
 })

Simple example of gradient descent in tensorflow
import tensorflow as tf
x = tf.Variable(2, name='x', dtype=tf.float32)
log_x = tf.log(x)
log_x_squared = tf.square(log_x)
optimizer = tf.train.GradientDescentOptimizer(0.5)
train = optimizer.minimize(log_x_squared)
init = tf.initialize_all_variables()
