 and latest from http://www.r-project.org/ I was a bit curious to know why the different licensing for R now (from GPL2 to GPL2- GPL 3)

LICENCE:

• No parts of R are now licensed solely under GPL-2. The licences for packages rpart and survival have been changed, which means that the licence terms for R as distributed are GPL-2 | GPL-3.



This is a maintenance release to consolidate various minor fixes to 2.13.0.


CHANGES IN R VERSION 2.13.1:

  NEW FEATURES:

    • iconv() no longer translates NA strings as "NA".

    • persp(box = TRUE) now warns if the surface extends outside the
      box (since occlusion for the box and axes is computed assuming
      the box is a bounding box). (PR#202.)

    • RShowDoc() can now display the licences shipped with R, e.g.
      RShowDoc("GPL-3").

    • New wrapper function showNonASCIIfile() in package tools.

    • nobs() now has a "mle" method in package stats4.

    • trace() now deals correctly with S4 reference classes and
      corresponding reference methods (e.g., $trace()) have been added.

    • xz has been updated to 5.0.3 (very minor bugfix release).

    • tools::compactPDF() gets more compression (usually a little,
      sometimes a lot) by using the compressed object streams of PDF
      1.5.

    • cairo_ps(onefile = TRUE) generates encapsulated EPS on platforms
      with cairo >= 1.6.

    • Binary reads (e.g. by readChar() and readBin()) are now supported
      on clipboard connections.  (Wish of PR#14593.)

    • as.POSIXlt.factor() now passes ... to the character method
      (suggestion of Joshua Ulrich).  [Intended for R 2.13.0 but
      accidentally removed before release.]

    • vector() and its wrappers such as integer() and double() now warn
      if called with a length argument of more than one element.  This
      helps track down user errors such as calling double(x) instead of
      as.double(x).

  INSTALLATION:

    • Building the vignette PDFs in packages grid and utils is now part
      of running make from an SVN checkout on a Unix-alike: a separate
      make vignettes step is no longer required.

      These vignettes are now made with keep.source = TRUE and hence
      will be laid out differently.

    • make install-strip failed under some configuration options.

    • Packages can customize non-standard installation of compiled code
      via a src/install.libs.R script. This allows packages that have
      architecture-specific binaries (beyond the package's shared
      objects/DLLs) to be installed in a multi-architecture setting.

  SWEAVE & VIGNETTES:

    • Sweave() and Stangle() gain an encoding argument to specify the
      encoding of the vignette sources if the latter do not contain a
      \usepackage[]{inputenc} statement specifying a single input
      encoding.

    • There is a new Sweave option figs.only = TRUE to run each figure
      chunk only for each selected graphics device, and not first using
      the default graphics device.  This will become the default in R
      2.14.0.

    • Sweave custom graphics devices can have a custom function
      foo.off() to shut them down.

    • Warnings are issued when non-portable filenames are found for
      graphics files (and chunks if split = TRUE).  Portable names are
      regarded as alphanumeric plus hyphen, underscore, plus and hash
      (periods cause problems with recognizing file extensions).

    • The Rtangle() driver has a new option show.line.nos which is by
      default false; if true it annotates code chunks with a comment
      giving the line number of the first line in the sources (the
      behaviour of R >= 2.12.0).

    • Package installation tangles the vignette sources: this step now
      converts the vignette sources from the vignette/package encoding
      to the current encoding, and records the encoding (if not ASCII)
      in a comment line at the top of the installed .R file.

  DEPRECATED AND DEFUNCT:

    • The internal functions .readRDS() and .saveRDS() are now
      deprecated in favour of the public functions readRDS() and
      saveRDS() introduced in R 2.13.0.

    • Switching off lazy-loading of code _via_ the LazyLoad field of
      the DESCRIPTION file is now deprecated.  In future all packages
      will be lazy-loaded.

    • The off-line help() types "postscript" and "ps" are deprecated.

  UTILITIES:

    • R CMD check on a multi-architecture installation now skips the
      user's .Renviron file for the architecture-specific tests (which
      do read the architecture-specific Renviron.site files).  This is
      consistent with single-architecture checks, which use
      --no-environ.

    • R CMD build now looks for DESCRIPTION fields BuildResaveData and
      BuildKeepEmpty for per-package overrides.  See ‘Writing R
      Extensions’.

  BUG FIXES:

    • plot.lm(which = 5) was intended to order factor levels in
      increasing order of mean standardized residual.  It ordered the
      factor labels correctly, but could plot the wrong group of
      residuals against the label.  (PR#14545)

    • mosaicplot() could clip the factor labels, and could overlap them
      with the cells if a non-default value of cex.axis was used.
      (Related to PR#14550.)

    • dataframe[[row,col]] now dispatches on [[ methods for the
      selected column (spotted by Bill Dunlap).

    • sort.int() would strip the class of an object, but leave its
      object bit set.  (Reported by Bill Dunlap.)

    • pbirthday() and qbirthday() did not implement the algorithm
      exactly as given in their reference and so were unnecessarily
      inaccurate.

      pbirthday() now solves the approximate formula analytically
      rather than using uniroot() on a discontinuous function.

      The description of the problem was inaccurate: the probability is
      a tail probablity (‘2 _or more_ people share a birthday’)

    • Complex arithmetic sometimes warned incorrectly about producing
      NAs when there were NaNs in the input.

    • seek(origin = "current") incorrectly reported it was not
      implemented for a gzfile() connection.

    • c(), unlist(), cbind() and rbind() could silently overflow the
      maximum vector length and cause a segfault.  (PR#14571)

    • The fonts argument to X11(type = "Xlib") was being ignored.

    • Reading (e.g. with readBin()) from a raw connection was not
      advancing the pointer, so successive reads would read the same
      value.  (Spotted by Bill Dunlap.)

    • Parsed text containing embedded newlines was printed incorrectly
      by as.character.srcref().  (Reported by Hadley Wickham.)

    • decompose() used with a series of a non-integer number of periods
      returned a seasonal component shorter than the original series.
      (Reported by Rob Hyndman.)

    • fields = list() failed for setRefClass().  (Reported by Michael
      Lawrence.)

    • Reference classes could not redefine an inherited field which had
      class "ANY". (Reported by Janko Thyson.)

    • Methods that override previously loaded versions will now be
      installed and called.  (Reported by Iago Mosqueira.)

    • addmargins() called numeric(apos) rather than
      numeric(length(apos)).

    • The HTML help search sometimes produced bad links.  (PR#14608)

    • Command completion will no longer be broken if tail.default() is
      redefined by the user. (Problem reported by Henrik Bengtsson.)

    • LaTeX rendering of markup in titles of help pages has been
      improved; in particular, \eqn{} may be used there.

    • isClass() used its own namespace as the default of the where
      argument inadvertently.

    • Rd conversion to latex mis-handled multi-line titles (including
      cases where there was a blank line in the \title section).

so thats who made chrome.




    

  • Will Google be able to monetize Chrome the way it has monetized Android (Atleast by locking in both search,computing and browsing platforms)? I like the Adblock extension- and I would be happy to see more paid extensions. or even two versions one free and other freer (in choice) browsers for ads /security etc. maybe even a premium paid browser which has tor embedded in it , adblock enabled in it, and encrypted chat (like Waste Again) as an extension…. Hmm Hmm Hmm There is a SOCIAL version of Chromium called Rockmelt used ironically by Google Social Nemesis -Facebook (see http://blogs.ft.com/fttechhub/2011/06/facebook-partners-with-rockmelt-on-building-a-social-web-browser/)
    • 

  • Will Google share more revenue with open source contributors and thus create a new path in open source revenue generation just like it did with online advertising as an industry? Hmm Hmm Hmm. or Will Facebook continue to lead the way with extensions and applications (which did predate the mobile app place- so thats one innovation u gotta give to Zuk’s boys 😉
    • 







Back to Chrome-




To change settings- chrome://settings/browser


but to check what Autofill Data is stored within chrome (thats your credit card and your web form information)


chrome://settings/autofill and chrome://settings/content has all your content settings




Well Chrome is very very secure, or as secure as a browser can be in 2011.


You can set up Google Sync to keep all your data in the cloud, and it has an application specific password as well.




So hopefully you will have much more fun enjoying hacking Chromium 😉
