Chromebooks, Notebooks, and Tablets --- and What To Buy

Chromebook, Notebooks, and Tablets

Chromebook

I have owned a Samsung Chromebook for 2 months now.  I am a fan. What a great little machine for $250.  Highly recommended.  I will buy the next version of the Chromebook if it improves just a little on the current version:

• the keyboard should be backlit
• the speakers should move from the underside of the notebook to the top and perhaps improve a little bit.
• the speed should increase just a little
• the vertical display angle should be a little better
• the USB ports need to provide sufficient charge for tablets

these are easy things to fix.

CPU Speed

Dell is in the news because computer sales have slowed down so badly that acquirers are now wondering about the future of the business.  Surprising?  It shouldn't be.  Computer speed innovation has decelerated.  According to Moore's Law, transistor count should double about every 2 years.  So, why is a $500 CPU today only 2 times faster than a $500 CPU from four years ago?   This CPU should be about 4 times as fast.  Or at least have 4 times as many cores.  Instead, the factor is about 2.0:

• Core i7-940 from November 2008 cost $562 at introduction: 5,471 Passmarks
• A Core i7-3930K in May 2012 costs $562: 12,079 Passmarks

Incidentally, both CPUs are named "i7", though they have different suffixes.  Most consumers don't even know that the two CPUs have different power.  They read i7, and believe they are the same.  If Intel wanted to confuse the value proposition for consumers, they have succeeded.

Desktop:  For a desktop, I want to buy an 8-core Haswell CPU with 64GB of ECC memory in an SFF (Shuttle XPC) for $1,000.  Not available before the end of the year.  Kaveri could become a good alternative with its unified-memory CPU/GPU architecture.

Portable Checklist

Notebook/Tablet/Alternative:  For an alternative device, I want something that does not exist.

• tablet and notebook as one device.  the CPU could be in the notebook base, while the tablet is the screen.  but not two OS's (like Asus Transformers).  if need be, the base (with backlit keys) can run a thin hdmi or displayport fiber+power cable from the base to the tablet screen.  wireless would be better.  it could use a few LEDs to signal the HDMI stream to the tablet screen and require line of sight.  face it---many of us computers in their beds or on their couches and can leave the base on the nightstand or coffee table.
• cool to the touch --- Haswell, 4 core, 16gb.  no audible fan.
• a 15.4" IPS 1080 tablet screen.  not retina, not 1366x768 lowq.
• Chromebook instant boot
• Linux secondary OS
• media consumption:  Blu-ray player in the base, tablet speakers towards the front ---good quality.  vga webcam.  reasonable good sensor, wide view.  skype-video.
• 5lbs package incl. power brick, 2lbs screen. 
• $2,000

this should be easy to produce.  the parts all exist individually.  but right now, out of the 8 bullet points, no more than 3 exist in any one device.

so, I really want to buy a detachable-panel Google Pixel with a 14"-15" 1080p screen, backlit keyboard, good speakers, and Haswell i5 or i7 ULV processor.  Ideally, the main processor would stay in the main keyboard unit, so the tablet screen could remain very cool and slim.  (it would just receive an hdmi bitstream with audio and send back touch and webcam.)  700g for the screen unit including battery (optional usb-3 connector), 1000g for the main CPU unit with keyboard and perhaps bluray.  wouldn't that be cool?!   $2,000?  no problem.

Where are the 15" screen tablets and detachables??

Of course, I need to wait for Haswell, anyway, but I am assuming the rest stays roughly the same. I may buy a Google Pixel, but only after the Pixel ships with Haswell.  I like the idea of running ubuntu or mint alongside chrome---and being able to switch between the two.  this should make for a killer notebook.  Note: Dell now sells a 13" XPS Ultrabook with Ubuntu.

Some more alternatives to purchase:  I could get be a 13-15" Haswell tablet, preferably one on which I can install linux and which I can use with or without a keyboard.

The Dell XPS18 is a bit too large.  5lbs

so is the Asus AIO 18".  5.3lbs

The Asus Transformer Book is a bit too small at 13" (but livable).  Problem: neither runs linux.  I want to run some version of linux.

the Lenovo wireless monitor Lt1423 could have been an option, too, when/if it ships---but it does not seem to have audio and webcam.

lenovo yoga 13, 3.3lbs.  because it can be rotated into portrait mode, 13.3 inches is ok.  modestly unpleasant heat.  not 1080p.

dell xps 12. only 12.5" at 3.3lbs.  keyboard backlit.  reasonable sound.

not hp envy x2---atom.  yikes.  alas, they just brought out a core version...worthwhile looking at.  4 lbs, though---then why not get the 18" XPS18?  cheap at $800.

not samsung ativ 700t or iconia w700 --- only 11.6" screen

samsung series V

asus taichi --- no.  what were they thinking with 2 displays?

The Nightmare Home Audio-Video Experience

All I want is to watch TV, Netflix, and Blu-rays.  Why can't this "just work"?

New Ubuntu System Installation - Checklist

May 2013

New Cinnemon Mint / Ubuntu System Installation - Checklist

I am switching back from OSX to ubuntu, because Apple OSX is moving towards retail customers, rather than pro customers. My full reasoning is explained here.  Long live linux ubuntu!

Here are my notes of how to install a new ubuntu system:

apt-get

• emacs and ess (note: ess may block emacs startup if R is not yet installed)
  sudo add-apt-repository ppa:cassou/emacs ; sudo apt-get update ; sudo apt-get install emacs24 emacs24-el
• chromium and chrome
  deb http://dl.google.com/linux/deb/ stable non-free main ; wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add - && sudo apt-get update && sudo apt-get install google-chrome-stable
• terminator; rightclick for preferences; and, after you made any changes in preferences, in the now existing  ~/.config/terminator/config

        size = 900, 600

• okular (remove sidebars, resize)
• mplayer
• Gstreamer-*
  the alternative is to install medibuntu:
  wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet updateapt-get -y update && sudo apt-get -y upgradeapt-get install app-install-data-medibuntu apport-hooks-medibuntuapt-get install w64codecs libdvdcss2apt-get install libdvdnav4apt-get install libdvdread4/usr/share/doc/libdvdread4/./install-css.sh
• openssh-server
• sshfs; fuse-zip
• gufw and set rules against unauthorized access (night, invalid logon attempts)
• backintime (exclude *.iso, .gvfs)
• unison
• mpg321 (mpg123 to play command line beeps)
• unity-chromium-extension: these may not work.  the gmail panel always quits
• indicator-multiload System Load Indicator (by Michael Hofmann for load status on panel).  then start it with the Unity menu (search System Load).  alas, this one does not work  under cinnemon mint, because it complains about missing gtop libraries
• apcupsd (for UPS) and configure it according to the USB community documentation.
• CanoScan LiDE 100:  libsane sane-utils xsane .  maybe it requires libsane-extras, too.  Thereafter, xsane works.  strangely, simplescan does not, even following this.
• davfs2
• flashplugin-installer; now in 12.10?
• MyUnity (maybe kill --- too dangerous)
• not used much: remastersys --- allows creating a dvd
• not used much: RecordMyDesktop
• not using much: gnome-gmail

Do not install either texlive or R through ubuntu. Their versions are seriously obsolete. Instead, follow the instructions below.

• remove thunderbird

Do not run MyUnity or compizconfig-settings-manager (ccms).  They hose the panel-service.  if you do this, you probably need to remove a lot of the dot (.compiz, .gnome, ??) files to get them back.DONT USE: ubuntu-tweak (though MyUnity does the same):

  add-apt-repository ppa:tualatrix/ppa ; apt-get update ; apt-get install ubuntu-tweak

For Adobe Acrobat, search for Software Sources, then enable "Other Software -> Canonical Partners". This also allows removing old repositories.  Then apt-get install acroread .  Also, acroread does not work on the command line, but the GUI starter for Acrobat works.

Beyond apt

• vmware get vmware-player . then "bash VM*".  if you want,
     ln -s /usr/bin/vmplayer /usr/bin/vmware-player.Note: everytime the host kernel or any vmware item is updated, you need to drop to the shell and run vmware-player while su by hand.  somehow, the GUI authorizer is broken.
• skype from skype's website.  note that ubuntu has trouble with some logitech webcams.
• TeXLive, install from source, following http://www.tug.org/texlive/quickinstall.html.  the main program is
     install-tl-unx.tar.gz
  make sure to set path to /usr/local/texlive/2012//bin/x86_64-linux/. Next, we need to install lucida fonts.  so
      echo "Map lucida.map" >> `kpsewhich updmap.cfg` ; updmap ; texhash
• R installation instructions are at

     http://cran.r-project.org/bin/linux/ubuntu/README
  

  Basically, include

    deb http://cran.stat.ucla.edu/bin/linux/ubuntu raring/
  

  in /etc/apt/sources.list, add the signage
  

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
  and execute
    apt-get update; apt-get install r-base
  and immediately install libatlas!!  R is 3 times faster with it than with the standard BLAS library that ships with cinnemon mint 15 olivia.  OSX has this already set.

• Good ssh key instructions can be found at http://www.g-loaded.eu/2005/11/10/ssh-with-keys/
  Make sure to choose good pass phrases. Basically, you need to do the following on your new client:

     client> ssh-keygen -t dsa -f ~/.ssh/id_dsa
     client> cat ~/.ssh/id_dsa.pub  | ssh name@server "cat >> ~/.ssh/authorized_keys"
     client> chmod -R 0600 ~/.ssh ; chmod u+x ~/.ssh
     client> ssh-add
  

  and add a MaxAuthTries 5 and ServerAliveInterval 60 to /etc/ssh/sshd_config.
• in /etc/default/grub, remove the "QUIET" from GRUB_CMDLINE_LINUX_DEFAULT, and change the GRUB_TIMEOUT to 5, then run update-grub
• change /etc/grub.d/30_os-prober to timeout 3 instead of 0 (to get a menu at boot)
• for SSD, enhance disk checking but turn off journaling: tune2fs -c 1 /dev/sda1 ; unmounted, you should tune2fs -O ^has_journal /dev/sda1. Then add discard to the options in /etc/fstab
• kdebugdialog (not as su, but as logged in) and then disable all debug output
• link open to gnome-open to ~/bin/open
• make anacron less quiet: change -q in /etc/cron.d/ ; possibly change daily exec time from 7am to 3am
• transfer .bash* , .emacs, src/* bin/*, /usr/local/texlive/ ; also .ssh
• google office (GWoffice):

•   add-apt-repository ppa:tombeckmann/ppa ; apt-get update ; apt-get install gwoffice

• Handbrake video converter:
  add-apt-repository ppa:stebbins/handbrake-snapshots
  apt-get update
  apt-get install handbrake-gtk handbrake-cli
• not needed in cinnamon mint apt-get remove unity-lens-shopping
• does not work: edit /etc/X11/Xsession : line 83: exec >>"$ERRFILE" 2>&1  should be exec >> /dev/null 2>&1
• for extra security, hide sudo somewhere else
• for the backup hard drive, use hdparm -S 12 /dev/sdb1 (60 seconds)
• Grive --- doesn't seem to work too well:
  sudo add-apt-repository ppa:nilarimogard/webupd8
  sudo apt-get update
  sudo apt-get install grive

Music:

• on3radio stream:

   http://gffstream.ic.llnwd.net/stream/gffstream_w9a
  

  and kcrw is

    http://stream-24.shoutcast.com:80/kcrw_eclectic24_mp3_128kbps 

  make sure to remove the final '/' from the link in rythmbox properties. (typically, a radio app will write a *.pls file in downloads, which contains the link.

settings---change timeouts.  hot corner on the right, not left.

Others:

• calibre book reader
• reinstate cron jobs

Much More Complete

debianhelp has posted http://debianhelp.wordpress.com/2012/03/09/to-do-list-after-installing-ubuntu-12-04-lts-aka-precise-pangolin/ .  In fact, it is so complete that finding one's way around it is painful.

Panel

The following apps live on my panel: chrome, Terminal, Homefolder, Ubuntu Software Center, Settings, Rythmbox, System Updater, Workspace Switcher, VMWare, Acrobat.

emacs, tex, and R are all usually invoked from my terminal.

Missing From Linux

A lightweight clean html editor and mailer.  even this blogger up produces nasty html markup that is difficult to correct with emacs.  kompozer has the wrong colors.
figure out backintime's scheduling and retrieval
how to move the menu from the top panel line to *both* the top pane line and to each window menu
improve terminal --- different colors for different machines, c-n, c-v, c-x.  add "open" to right click
Evernote -- maybe Everpad?
how to stop windows from snapping to the top panel??
alt-ctrl-hotkey on apple keyboard -- how do I abort X server and switch to virtual terminal?
create backup bootable own drive

try teamviewer for remote control.

write a script that checks all of the above and does whatever is still missing.

printer installation -- wonderfully easy.  alas, Ricoh copier printers do not work.  on ubuntu, the first print job worked fine to my lexmark usb printer; the next one produced garbage.

scanner installation -- xsane works for canon, but not the easier ones

Problem for Non-Linux Users

for some reason, 12.04.1 booted into a text login, instead of the gui login.  this persisted over 2 reboots and then disappeared.  go figure.  this would be a serious problem for a non-unix expert.  I don't know why.

there was also a problem where it would sometimes not automatically continue on restart, which was a problem for an unattended server.

Where Apple OSX is Really Headed

Many pundits have opined where OSX is headed.  They are all wrong.

Here is my prediction: By 2018, Apple will stop supporting OSX for non-Apple app programmers, and require that all apps be purchased through their Appstore.  OSX will become like iOS in this respect, too, as it has in other respects.

Frankly, this will make sense for 99% of Apple's retail clientele.  It will prevent lots of malware and reduce support costs.  And it will make Apple money, because Appstore purchases earn Apple money.

Why wouldn't Apple focus on building certified Apple app programmers and abandon non-Apple-app programmers?  Maybe 1 in 100 buyers buy Apple hardware to program their computers for themselves, so the sale losses to programmers who would switch away to other hardware will be small. (Unfortunately, I am in the 1% minority.)  WIth enough of a retail base to reach, OSX and iOS app developers will stay and be certified.  To write a native OSX computer program will require a revocable developer id unlock code and take place in a trusted environment.  (The certified Apple developers will like some aspects of such an ecosystem, because it will cut down on free competition.  They won't like sharing revenues at the Appstore.)  But ultimately, it does not matter what software developers like.  When the Apple Mac base is large enough and the Appstore cut is bearable, they will stay.

Ultimately only two aspects will matter to Apple: making the retail clientele happy and increasing Apple's revenues.  And going the "certified developer only" route is a win-win for both.

My guess is that some non-certified programming will be allowed in interpreted sandboxed environments, at least for a while.  This will cover the needs of students learning how to program.  In this respect, it will be different from iOS, where all programming environments are outlawed. 

One alternative would be a locked OSX default mode that can be unlocked by end users.  of course, once software can unlock the computer mode, so can malware---and apple revenues will be lower, because developers could escape the Appstore.  This end-user switchable OSX will probably be an interim step.

I believe that this future direction of Apple is almost inevitable once Apple becomes a dominant power in high-end personal computer sales and developers can't escape.  The only thing that can stop it is a slowing of their momentum in PC sales, which could force them to take PC competition more seriously.  But if the Apple momentum continues, then if Apple will not go the lock-down route, they will be making a huge business mistake.

We nerds are all in trouble.

Hardware is in trouble.  And, this time, it's not even an attack by the copyright kingdoms.  Its just that there is nowhere to go.  Where can we go?  Sun is gone.  Windows is going towards trusted computing, so we will also soon no longer be able to use Windows hardware (esp. hardware from the big vendors, like Dell and HP, although all they do these days is try to ape Apple, and not very well).  There is no great hardware vendor for high-quality open software desktops.  (This is why we nerds also buy Mac hardware.)

Software is in trouble, too.  Ironically, it is exactly OSX that has pretty much killed linux on the desktop.  We have to preserve our expertise---linux on the desktop---tying the projects over until we (the nerds) will be forced to depart OSX.  We should never underestimate the future, but we may not have anywhere obvious to go.  

Richard Stallman is right to fear Apple more than Microsoft.  I do, too.

Update: http://arstechnica.com/apple/2012/09/two-months-later-developers-mostly-positive-about-os-xs-gatekeeper/  --- it's coming quickly.

PS: Here are some minor squawks about OSX: the file system could more robust.  There is no ability to lock a cpu core to a virtual machine.  Preview.app has been going backward IMHO after Snow Leopard; it is not storing its page view settings properly.  There is no package manager...well, this is what the appstore will become.  OSX feels slow relative to linux.

R Annoyances and Gripes

R is a superb data analysis and graphing program. It has a solid programming environment. It has great docs, although I wish it had even more "see also" and more "examples" in the man pages. many CRAN packages are great. the R team members and folks answering r-help posts are saints, though some of them can be quite grumpy.

[I try to integrate some of the comments from below.  thx everyone.]

Alas, because R is so good, I am probably too tempted to write too many programs in R. Unfortunately, for a generic programming language, R still lacks some sugar.

1. It should be possible for a user to set an option that forces aborts immediately upon read access into a non-existing list item or data frame column (i.e., if this data frame or list that has not yet been initialized). instead, R simply silently yields NULL. Try it!
   

   .GlobalEnv$misspelled
   

   or even
   

   .GlobalEnv$misspelled[100] 
   

   do not cause a program abort. good luck finding the error later.  Gabor also suggests using the .GlobalEnv[["misspelled"]] construct, which does check.  Still, the '$' syntax is often so much nicer....
2. It should be possible for a user to turn automatic recycling off. I have programmed bugs which I could have caught earlier if the program had bombed on non-conformable assignments. why do we need BY DEFAULT  the following to work?
   

   v←1:4
   w←1:8
   z←v+w
   

   Really? Are you sure it is what you wanted? If it really is, you should set an option first, or better yet, rep(v( yourself.  there should be an option(recycle="default"|"scalars-only"|"never").  you can even leave the current default, but allow *me* to turn this off.  over time, packages may switch their model, and, by default, everything should still just work without changes.
3. An error should always clearly identify the lines in a program where it occurred.
   Simple Fix: Turn on

     options(error=recover)

   again and run my program again to understand where my program bombed.
4. An assert()should be built into the R language---assert should be like a stopifnot() function, but with a cat message function. So, I could write
   

   assert( ncol(x)==ncol(y), "Sorry, but ncol(x)=",ncol(x)," != ncol(y)=", ncol(y), "\n")

   the big advantage of building assert into the language, rather than having it user defined, is that an assert error will bomb showing the correct line, not an error inside the assert function, requiring a stack backtrack.  it could even drop you into the right stack-frame at that time---an advantage currently only for the main control logic but not logic inside functions is the immediate ability to examine the variables that were associated with the failure.
   
   Programming by contract would be even better. (package testthat has some testing functions, but it's not the same.)   Perhaps a novel pretty syntax, like
   
   

   [ ncol(x) != ncol(y) => "Sorry, but", ncol(x), "is not", ncol(y) ]
   

   
   would be even better, abusing both the '[' when it starts a statement and and '=>' . Such readable and SHORT syntax, when paired with a clear error on which line the error occurred when it triggers, would encourage everyone to use a lot of assertions, including at each function start and end.
5. there is no way for an end user (not library writer) to add his own function doc to the set of docs that one can interrogate with '?' request for doc about a function.  suggestion: use package skeleton for building full packages.  nothing for end users, though.
6. similar---can we please add something akin to the perl6 pod to R?  please adopt some good features from perl, even though R is of course not perl.  PS: and where/what are the standard filename conventions? I think it is .Rdata for data files. right? (Is it .Rh for R inclusion files?)
7. nice but unnecessary: Syntactic sugar: would it not be great if '$' inside a string would do a paste-with-autocollapse? How ugly is it to call my function as
   

   f( paste("msg is '",m,"'", collapse="") )
   

   compared to the more readable
   

   f("msg is '$m'")
   

   ?  but the simpler paste0 goes a long way...
8. There should be an easier way to assign from a list to multiple objects
   

   (a,b) ← f()
   

   Gabor G created a great R function that facilitates this, but something like it should be built in.
9. R should be smart enough to understand one special case to allow quickly assigning to individual elements in a data frame. Believe it or not, but
   

     bigframe$a[12]←12
   

   will actually copy the bigframe object a few times, instead of just replacing the single cell's content. if bigframe is big, you can count the number of assignments per second on an Intel core 2012 system. yikes! of course, I know this now, but all novices probably learn this the hard way. they may get the impression that R is slow when they (like I did before I knew) write,
   

     for (i in 1:10000) bigframe$soln[i]← uniroot(myf, c(-Inf,Inf), i)
   

   But
   

     for (i in 1:10000) soln[i]← uniroot(myf, c(-Inf,Inf), i);
     bigframe$soln←soln; rm(soln)
   

   is reasonably fast. (The data.table R package is one way to get around this, but again, this is not what novices would know.)  This is important to fix IMHO.
10. nice but unnecessary.  I would love to have many of my functions defined at the end after my control logic at the start of my R code. thus, I would love it if I could instruct R to scan the source file for functions first before executing---as it is in perl. This behavior could be enabled by a user and not be the default.
11. probably a bad idea on my part.  there should be "static" (local persistent) variables in R. Use very sparingly, of course.  I would use it for in-function caching of previously seen/handled cases.

Some more minor gripes:

1. load() should have an option to write to stderr what objects are being loaded. in fact, such stderr output should probably be the default to remind the user, just as library loading usually does.  load() should also have an option to check its environment first to see if the object already exists, and load it only when still needed...sort of like a library() invocation.
   
2. there should be a legacy option, without which demoted features cause warnings and errors...and let's demote attach and detach.
3. if
   

     option(na.rm=TRUE)
   

   then mean(c(1:5,NA)); cor(c(1:5,NA), c(rnorm(6)) should give values. I have read about na.action, etc, but I could never figure out how to make it work.  lm() ignores NA even silently without any option.  why one and not the other?  of course, it doesn't have to be fully consistent from day 1.  but let's just get it started.  mean, sd, var, median, summary could be fixed.
4. bad idea on my part.  paste0 is better. There should be
   

   option(pastechar=" ")
   option(catchar=" ")
   

   to allow setting of the default sep for paste and cat. Incidentally, I like space to be the default to separate the elements in a vector, but I do not like space before and after separate arguments to paste and cat. I can add the latter myself more easily.
5. The commonly used descriptive summary() for a data object should also include the number of observations, the number of NA's, and the sd as built in; possibly even the T-stat.  I have programmed my own summary(), but this would be a good idea for everyone.
6. the parallel core library is superb. finally an easy way for me to use the 8 cores in my Mac Pro! however, mclapply does not make it easy to figure out how many times the function was called. will it take another 100 days, or another 100 seconds to finish? tough to guess. a progress counter would help.  Workaround:
   

   sleep1sec ← function(i) {
      counter<←counter+1;
      cat("Counter=",counter, " i=",i, "\n");
      Sys.sleep(1); rnorm(1) };
   mclapply(1:1000, sleep1sec) 
   

   but unfortunately each process has its own global counter. still better than no process indicators whatsoever, though.
7. the two graphics plotting systems should really be replaced by one. I also don't understand the difference between S3 and S4. do we need this?
8. very minor: sleep() should be a function that sleeps, not a data object that contains how much students slept. Sys.sleep() is what I need. ok, this is a very trivial gripe. but the docs for sleep (?sleep) should say "see also Sys.sleep".
9. why do I need both source and load ? couldn't these functions detect whether I am reading an .R or an .Rdata file and invoke the right one? both are R objects.
10. ok.  I need to use the apply family more.  Does anyone have an idea how to abbreviate the common
    

    mylist← rnorm(5); for (si in 1:length(mylist)) { value← mylist[si]; ...
    

    into something that reads quicker and still has a counter?  In R, having a counter is more important than it is in perl, because iterative list creation via push is discouraged relative to list creation via indexed assignment (for speed reasons, I think).  Maybe a new iterator, like
    

    iterate(si, value, rnorm(5)) { ...
    

    perhaps? I know this is wild syntactic sugar, but then I write user programs and not computer languages, and I would like my programs to be readable and elegant, more than I would like R to make perfect sense.
11. why don't more options allow mnemonics? for example, options(warn=1) means what? couldn't it be options(warn="immediately"); or, why not text(...,pos="left"), instead of test(...,pos=2)?
12. why do some functions wrap quotes around variables? For example, why is it library(something), instead of library("something")? something without quotes should be a variable. same thing for select in subset statements. tell me: what is
    

    d <- data.frame( a=1:3, b=5:7 )
      a <- "b" ; a2 <- "b"
      subset( d, TRUE, select=c(a) )
      subset( d, TRUE, select=c(a2) )

    ok, if it were always optional to omit the quotes, I would understand it. but it isn't the case with a subset-select, in which I want to delete a variable.  subset(d, TRUE, select= -c(x)) works, but subset(d, TRUE, select= -c("x")) does not.  huh?
    
13. merge should also be capable of merging by rowname, not just by columns.
14. Core Team: Make your life easier!  Would it be possibly to pseudo-wikify the docs? I.e., allow collaborative suggestions? I often think "this ?... should have included a see also to ...", but there is no easy way for me to fix it right there and then for future users. the existing R bug+suggestion system is ok for bigger issues, of course, but painful for these small items. I also wonder whether my suggestions are actually welcome or a distraction. and, of course, I understand that any short edits should require package maintainer approval in the end. my guess is that many suggestions to the docs would be for the better...and, unlike code itself, docs are something that ordinary users can contribute to. after all, it is they who often need and use the docs the most.

Please don't take these as criticisms of the work that the R team has put into R. It is easier for users to gripe than it is to implement features. And obviously I am not willing or able to put these features in myself.

Of course, R has so much magic and so many features that it may well be the case that many of my gripes above already have solutions, but I just don't know them. :-( if you see any, let me know, please. And let me know what gripes should I have complained about that I missed, too.


PS: Next, I need to figure out how to create LaTeX output of regressions and data systematically. there are a few packages on cran, but I am not yet sure which one I want to use.

PPS: I just discovered Doug Bates' blog on Julia. Interesting. I don't miss what Julia provides (e.g., the JIT) too much. the stuff above bothers me more.

What Android tablets could do better than the Ipad

How can Android beat the iPad 2?  Tough.  The iPad install base is large, and the iPad is simply a great product.  But the iPad 2 is not perfect.  In any case, if Android does not a better product, it will never catch on.  So, from the perspective of an adult user (i.e., not for primary use as a gaming machine), what could an Android tablet do better than the iPad 2, which would lead me to trade mine in?

1. Better cameras.  The ipad 2 cameras are awful, even for skype.  I don't mean (just) the resolution.  I mean the lens angle.  It is not wide enough.  You have to hold the Ipad about 4 feet away from your face in order not to look like a moon face.  It also means that inevitable shaking makes the system worse.
2. Better software developers.  For example, tap into better system software through outside ideas.  Allow awesome third-party system software to take control of the iPad--but only if it has been carefully checked and vetted.  (For example, I would buy a tablet that allowed me to set up a "point system" for my kids: if you do educational games for x hours, you get to play any kinds of games for y hours.  No one other than Apple can implement this on the iPad.)  Offer a venue for Android developers.  Oh, and build faith among your developers.  I don't mean be static in terms of always sticking religiously to legacy interfaces.  See, most external Apple developers do not trust Apple, and rightly so.  They understand that Apple may pull the rug out from under them at any moment if Apple finds it in its own interest.  Apple's predatory behavior vis-a-vis its developers is Android's single biggest asset, and Apple's single-biggest weakness.  If Android were just competitive, every developer would prefer putting their stakes with Android, and not with iOS.
3. Better web browsing.  Safari sucks.  I want real tabs.  Background loading, even if I exit it.  (Flash is not half as important as the basic experience.)  Since I am at it, make sure the other base software for adults is better, too.  Offer a better skype and email client than what exists on the iPad.  (Skype, where is the iPad client?  Why am I running an iPhone skype??)  Lure all the magazine and book publishers to go to Android.  Work with Amazon.
4. Offer some better technology.  Take some risks to lock up something unique.  Offer a truly foldable tablet, where the fold is seamless.  Or a flexible tablet.   Or a sun viewable tablet. Wireless charging. (Retina display?  Who cares.  The ipad is plenty readable, even today.  The resolution battle and battery life battles, like the CPU battles of old, are mostly over.  1000x1000 on a 10" tablet is decent.  8 hour battery life is decent.  Yes, you can be better, but this is not what will make or break the next system.)   There are plenty of better tech solutions that have failed.  But there are few solutions without a compelling advantage that were able to overtake a market leader.  Apple is a smart leader.  They learned how important market share is fighting Intel and Microsoft.  Apple now has the iOS software base.  They have the user base.  Business as usual just won't work for Android.  Android just has to become better than the iPad, or it will never catch on.
5. Offer an optional "pen" mode for more accurate drawing with a stylus.  Offer voice recognition software deeply embedded in the system.  

Of course, the whole tablet experience has to be right, too.  Be as good when you can be.  The device should be as thin and nice (and crapware-free) as the iPad.

PS: This is also why google TV failed---it has to be simple and integrated.  A TV that has everything seamlessly integrated, without cables, complex menus, etc.  The DVD, Bluray, DVR, etc., all seamless.  One remote control.  My grandmother would have to be able to operate it.

The Secret To Making Great Movies

Sadly, there is no secret to making great movies.

The "secret" is having a good story.  A story that is interesting.  A story in which it is not obvious what will happen next, yet you can hardly wait to see what will happen next.  A story in which everything makes sense (in the end).  A story which is believable.  A world.

This is why good theater works, even though it is on a small stage in an obviously unbelievable setting.  The story must be engaging.  Think the "Usual Suspects."  Or "The Lives of the Others."  Or "No Country for Old Men."  Or "Snatch."  Or "The Wire."  Or "Downton Abbey."  Or many other movies and series that did not cost an arm and a leg to make.

You don't need a great director, great actors, high production budgets, or special effects.  Yes, these can help.  But a great story will make mediocre "everything else" appear great.  A boring story will make great "everything else" appear mediocre.

Of course, some stories may intrinsically require a great director, great actors, huge production budgets, or great special effects.  For Bladerunner, the feeling of future LA was vital.  For the series Rome, a believable Rome 2000 years ago was vital.  For the liquid metal robot in Terminator II, the special effect was vital.  (But note that Terminator I, which is just as good, was made on a shoestring.)  For Lawrence of Arabia, how could you film this, if not in the desert with hundreds of actors and extras?   For the Godfather, it had to be Martin Scorcese.  And Al Pacino.  And...

But, in the end, nothing other than a good story really matters.

So, why does Hollywood--and, worse, network television--produce so much shit?  It's because Hollywood is not out to make great movies.  It's out to sell movies.  If movies like "Independence Day" and reality TV sells, then this is what will be produced.

Of course, I think that Hollywood is also too short-sighted.  Making a good-story movie is a larger risk than making "The Matrix 5" or "Spiderman 8."  But, a new world with a new story can itself create more spinoffs.  Of course, even a good film (like Rocky 1) will then warp into a bad one (like Rocky 14), but I can live with this.

And, of course, convincing the folks providing the cash is easier said than done...
