Using R for random number creation from time stamps #rstats

Suppose – let us just suppose- you want to create random numbers that are reproducible , and derived from time stamps

Here is the code in R

> a=as.numeric(Sys.time())
> set.seed(a)
> rnorm(log(a))

Note- you can create a custom function  ( I used  the log) for generating random numbers of the system time too. This creates a random numbered list of pseudo random numbers (since nothing machine driven is purely random in the strict philosophy of the word)

Possible applications- things that need both random numbers (like encryption keys) and time stamps (like events , web or industrial logs or as pseudo random pass codes in Google 2 factor authentication )

Note I used the rnorm function but you could possibly draw the functions also as a random input (rnorm or rcauchy)

Again I would trust my own random ness than one generated by an arm of US Govt (see )

Update- Random numbers in R


The currently available RNG kinds are given below. kind is partially matched to this list. The default is "Mersenne-Twister".

The seed, .Random.seed[-1] == r[1:3] is an integer vector of length 3, where each r[i] is in 1:(p[i] - 1), where p is the length 3 vector of primes, p = (30269, 30307, 30323). The Wichmann–Hill generator has a cycle length of 6.9536e12 (= prod(p-1)/4, see Applied Statistics (1984) 33, 123 which corrects the original article).

A multiply-with-carry RNG is used, as recommended by George Marsaglia in his post to the mailing list ‘sci.stat.math’. It has a period of more than 2^60 and has passed all tests (according to Marsaglia). The seed is two integers (all values allowed).

Marsaglia’s famous Super-Duper from the 70’s. This is the original version which does not pass the MTUPLE test of the Diehard battery. It has a period of about 4.6*10^18 for most initial seeds. The seed is two integers (all values allowed for the first seed: the second must be odd).

We use the implementation by Reeds et al. (1982–84).

The two seeds are the Tausworthe and congruence long integers, respectively. A one-to-one mapping to S’s .Random.seed[1:12] is possible but we will not publish one, not least as this generator is not exactly the same as that in recent versions of S-PLUS.

From Matsumoto and Nishimura (1998). A twisted GFSR with period 2^19937 – 1 and equidistribution in 623 consecutive dimensions (over the whole period). The ‘seed’ is a 624-dimensional set of 32-bit integers plus a current position in that set.

A 32-bit integer GFSR using lagged Fibonacci sequences with subtraction. That is, the recurrence used is

X[j] = (X[j-100] – X[j-37]) mod 2^30

and the ‘seed’ is the set of the 100 last numbers (actually recorded as 101 numbers, the last being a cyclic shift of the buffer). The period is around 2^129.

An earlier version from Knuth (1997).

The 2002 version was not backwards compatible with the earlier version: the initialization of the GFSR from the seed was altered. R did not allow you to choose consecutive seeds, the reported ‘weakness’, and already scrambled the seeds.

Initialization of this generator is done in interpreted R code and so takes a short but noticeable time.

A ‘combined multiple-recursive generator’ from L’Ecuyer (1999), each element of which is a feedback multiplicative generator with three integer elements: thus the seed is a (signed) integer vector of length 6. The period is around 2^191.

The 6 elements of the seed are internally regarded as 32-bit unsigned integers. Neither the first three nor the last three should be all zero, and they are limited to less than 4294967087 and 4294944443 respectively.

This is not particularly interesting of itself, but provides the basis for the multiple streams used in package parallel.

Use a user-supplied generator.


Function RNGkind allows user-coded uniform and normal random number generators to be supplied.

Creating an Anonymous Bot

or Surfing the Net Anonmously and Having some Fun.

On the weekend, while browsing through I came across an intriguing offer-

Basically projects asking for increasing Youtube Views-


So this is one way I though it could be done-

1) Create an IP Address Anonymizer

Thats pretty simple- I used the Tor Project at

Basically it uses a peer to peer network to  connect to the internet and you can reset the connection as you want-so it hides your IP address.

Also useful for sending hatemail- limitation uses Firefox browser only.And also your webpage default keeps changing languages as the ip address changes.


The Tor Project is a 501(c)(3) non-profit based in the United States. The official address of the organization is:

The Tor Project
969 Main Street, Suite 206
Walpole, MA 02081 USA
Check your IP address at

2) Creating a Bot or an automatic clicking code ( without knowing code)

Go to

Remember when you could create an Excel Macro by just recording the Macro (in Excel 2003)

So while surfing if you need to do something again and again (like go the same Youtube video and clicking Like 5000 times) you can press record Macro

  • Do the action you want repeated again and again.
  • Click save Macro
  • Now run the Macro in a loop using the iMacro extension.

see screenshot below-

Note I have added two lines of code -WAIT SECONDS= 6

This means everytime the code runs in a loop it will wait for 6 seconds and then reload.

However I recommend you create a random number of wait seconds using Google Spreadsheet and the function RANDBETWEEN(5,400) (to limit between 5 and 400 seconds) and also use CONCATENATE with click and drag to create RANDOM wait times (instead of typing it say 500 times yourself)


That’s it – Your Anonymous Bot is ready.

See the  analytical results for my personal favourite Streaming Poetry video

Easy isn’t it. Lines of code written= 0 , Number of Views =335 (before I grew bored)

Note- Officially it is against Youtube Terms to  use scripts or Bots so I did it for Research Purposes only. And the needs to look into the activities underway at and also and

The final word on these activities is by or
