Merlin Mann’s recent series of podcasts on GTD,
I’m getting back on the GTD wagon (for about the 100th time). I read
Getting Things Done in 2002 and have been
trying to implement it ever since. I’ve had periods where I followed
it religiously for a month at a time, but it’s never completely stuck.
From what I hear, this is normal and I accept it now. This won’t be
the last time that I restart GTD. Even when I’m not actively using
GTD, I think in GTD terms, thinking about next actions and projects
and ruthlessly placing projects on the backburner. I just have trouble
sticking with the entire GTD workflow, especially the ubiquitous
capture (I trust my brain too much) and the weekly reviews (they just
seem too painful). I’ve used every online and offline tool in the
book, too. Despite not doing so great with GTD, I’d say my life is an
So why try again? Each time I have gotten back on the bandwagon, I’ve
had a surge in productivity. I wrote more. I made some clear decisions
on issues that I had been procrastinating on. I wouldn’t be surprised
if each of my major life improvements over the past 10 years was
associated with a time where I got back on the GTD wagon. I can’t
prove that, because I don’t keep enough details, but I always feel
better and think clearer when I’m on GTD.
But, I’ve failed so many times… what kind of hubris makes me think
I’ll get it this time?
“Fall down seven times, get up eight.”
Parenthood has taught this to me. Of course we don’t expect our kids
to learn each skill the first time they try. We expect that walking
and reading and writing and bike-riding will take time, multiple
efforts, and multiple failures. But eventually they will get it. Yet,
with each failure, kids get upset (to varying degrees). The answer at
that point is not to tell them to give up. Yet, that’s what I do to
myself. So, I’m going to treat myself like a kid and let myself fail,
understanding that each failure will get me closer to that one time
where I will succeed.
I think twitter and facebook stunt my writing. The more that I read
tweets, the more self-conscious I get when I write. Not that my
writing is all that original, but I still feel that it is something
that comes from me. I worry so much about presenting ideas of others
as my own without even remembering that I had seen the ideas before.
In the old days, the things that I read were long form. Books,
articles, maybe blog posts. They each left an impression on me, maybe
good, maybe bad, but I had a sense where they were coming from. When I
wrote I could reliably say where the inspiration for my idea had come
from. Now with twitter, I see all these ideas and thoughts, some of
which are interesting, but few of which leave a lasting impression on
me. So now I have this fear that the things that I am considering my
own ideas are actually the ideas of others, improperly attributed. Of
course, that’s silly. No idea is original, but it’s just serious
enough to stifle my writing. Because, as a writer, I am the
scaredy-cat of all scaredy-cats and any criticism of my writing bites
deep to the heart. I also know that this is something that I just need
to get over. You cannot express ideas without inviting criticism.
I also don’t just want to let criticism fall off me. I want to learn
from critics. But saying all that doesn’t necessarily make it any
easier. Even writing this post, I feel like a fraud. I’ve said that
I’m a writer a couple times up there, but what evidence do I have to
support that claim? Most of my blog posts are so simple or technical
or repetitive. Nothing that would strike me as an ‘original idea’.
This whole post makes it seem like I am more important or better than
I really am.
What is my point with all this? I want to be able to write. I know
that there are people out there who could benefit from things in my
brain (maybe not a lot). I know that there are people out there who
can help me (in ways that I can’t even expect). So, I want to write
and I want it to be freely flowing and I don’t want to force myself to
feel that what I am writing is useful or authoritative or perfect. I
apologize to you, Vinod, my biggest critic. I know that you are
cringing inside because you’re thinking that anyone who reads this
will think that you are so full of yourself for even considering
yourself a writer. But, this is my first step in letting my guard down
to get this blog flowing. Because I do believe that writing is healthy
and will make me a better person.
In addition to committing to blogging more frequently, I’m also going
to try a twitter hiatus for a week and see what happens.
Now that we have 3 kids, I’m always internally comparing one to the
other. Sure that’s not healthy and will probably breed resentment in
them during their teenage years, but what’s a bad parent to do?
I need an app that takes 2 kids’ birthdays and then shows me what day
it was when the older kid was the age that the younger kid is now.
Wow, that’s a confusing sentence. In simpler terms, if I have a
3-year-old and a 1-year-old, then the app would show me the day that
the 3-year-old was 1.
Then, I want the app to take that date and go through all of my
personal files (photos, notes, twitter stream, facebook stream, etc.)
and show me what was happening in our life around that day.
In short, it would show a snapshot of what our life was like when the
older kid was the age that the younger kid is now. I’d call it
WhenIWasYourAge or something catchy like that.
Seems simple enough to build, but I don’t see myself getting to it
anytime soon. Smart people say to set your ideas free and if they love
you they’ll come back. (Wait, I think I’m mixing metaphors here).
I’m not the handiest guy in the world, so I’m pretty proud that I was
able to fix a flat tire on Kavi’s 12” bicycle.
DISCLAIMER: I have almost no idea what I’m doing. Follow my
instructions at your peril.
I’ve fixed flats before, but it’s been a long time. Fixing it on such
a tiny bike was a lot harder than I thought. The manual makes it seem
so simple. “Remove the wheel, take the tube out, patch the tube and
then replace the tube and tire.” Right… I got stuck at step 1.
Removing the wheel isn’t straightforward. Most of the videos available
online focus on adult-sized bikes which have quick-release tires. You
pull a release lever back and then pull the tire off. Kids bikes have
bolts instead of quick-release levers. You have to loosen the bolts,
but you don’t have to take the bolts completely off. You also have to
take off the plastic chain guard that prevents kids from rubbing their
legs against the chain. Finally, there’s this little metal piece that
attaches the wheel to the frame. I think it’s there for the
pedal-brake to work. In any case, you have to take that off. Once the
wheel is loosened, you have to unhook the wheel from the chain. This
is also easier in big bikes which have multiple gears, making it
possible to place the chain in a position to easily get it off the
wheel. In a kid’s bike, it’s harder. Once I loosened the bolts on both
sides of the wheel, I pushed the wheel a little forward, which
loosened the chain and made it easy to release from the chain.
The next difficulty was getting the tube out of the tire. All the
videos make this seem so easy. Place a tire lever in the tire to pull
it over the rim. Put another tire lever in and slide it around the rim
to get the rest of the tire out. Kavi’s tires are so tight that this
was impossible. I could get the first tire lever in, but when I put
the second tire lever in, it was completely immovable. There was no
way that I was going to be able to slide it anywhere. I finally found
a website where they recommended using a third tire lever. Put the
first two in a few inches apart. Then put the third one in another
inch away from the second one. Finally remove the middle one and move
it an inch past the third one. In this way, I was able to get the tire
I then got the tube out and found the leak. I placed a patch on it,
but when I reinflated the tire, the leaking air just pushed it’s way
through the patch. I tried roughing up the area with the roughing
tool, but that didn’t help. Finally, I resorted to the layman’s
favorite tool: duct tape. I placed the patch, then wrapped it with
duct tape. It’s held together for a few months now.
Hopefully Kavi will graduate to the next size bike before my handiwork
breaks down. On another note, Kavi was easily able to pick up the
basics of riding a bike by following the
I took off the training wheels and the pedals, which allowed him to
get the feeling of balancing the bike without having to keep his feet
on the pedals. Once he got that part, it was relatively easy for him
to balance with the pedals on. He also proved to be a much tougher kid
than I was. Everytime he fell, he got right back on.
Today, I listened to
Mark Aufflick’s interview where
he talks eloquently about starting your own business. I love the
perspective he had on his first business and how shutting it down gave
him the necessary (though painful) experience to make his current
business work. He also talked about the importance of computing
history especially given the availability of interesting subjects. He
ended with great advice on the importance of professionalism.
Paraphrased: “Make sure your team is the most professional side of any
I know Mark and
Mark from the
OpenACS glory days and it’s great to hear how
well they’re doing. Computing history was a prominent part of both
talks. I think this is important. Old ideas are always new again. Some
of the ideas that these pioneers had were only limited by the
horsepower we had to work with at the time. Now thanks to Moore’s law,
those limitations are gone, so we should re-investigate those ideas.
Or maybe we’re all just getting old and like to talk about the
good-old-days. :-) It’s nice to see that they both mentioned the
OpenACS period of their programming lives as important. It certainly
was for me. It was also great to hear Mark Aufflick’s voice for the
first time, even though I feel like he’s been a friend for many years.
As evidenced by the numerous blog posts documenting how to set this
up, it’s not straightforward. I recommend starting from scratch to
make sure everything is set up properly. Once you have it working,
then you can customize it. Make sure to start these commands in your
Create an empty .emacs.d directory and a subdirectory named with your
username. My username is vinod, so we’ll create a directory
structure called .emacs.d/vinod/. The emacs-starter-kit tells emacs
to automatically load any elisp files from that special directory, so
you’ll always have a place to drop custom elisp files.
vinod:~$ mkdir -p ~/.emacs.d/$USER
Create a file named .emacs.d/init.el with the following contents:
(require'package)(add-to-list'package-archives'("marmalade"."http://marmalade-repo.org/packages/"))(add-to-list'package-archives'("melpa"."http://melpa.milkbox.net/packages/"))(package-initialize)(when(not package-archive-contents)(package-refresh-contents))(defvarmy-packages'(starter-kitstarter-kit-bindingsstarter-kit-jsautopairyasnippetauto-completefuzzy)"A list of packages to ensure are installed at launch.")(dolist(pmy-packages)(when(not (package-installed-pp))(package-installp)));; autopair and yas in all modes(autopair-global-mode)(yas-global-mode1);; autocomplete(require'auto-complete-config)(setqac-dictionary-files(list (concatuser-emacs-directory".dict")))(ac-config-default);; hack to fix ac-sources after pycomplete.el breaks it(add-hook'python-mode-hook'(lambda ()(setqac-sources'(ac-source-pycompleteac-source-abbrevac-source-dictionaryac-source-words-in-same-mode-buffers))));; Set up python-mode(setqpy-install-directory(concatesk-user-dir"/python-mode.el-6.0.12/"))(add-to-list'load-pathpy-install-directory);; this will show method signatures while typing(setqpy-set-complete-keymap-pt)(require'python-mode);; activate the virtualenv where Pymacs is located(virtualenv-workon"default/")(defunload-pycomplete()"Load and initialize pycomplete."(interactive)(let* ((pyshell(py-choose-shell))(path(getenv"PYTHONPATH")))(setenv"PYTHONPATH"(concat(expand-file-namepy-install-directory)"completion"(if path(concatpath-separatorpath))))(if (py-install-directory-check)(progn(setenv"PYMACS_PYTHON"(if (string-match"IP"pyshell)"python"pyshell))(autoload'pymacs-apply"pymacs")(autoload'pymacs-call"pymacs")(autoload'pymacs-eval"pymacs")(autoload'pymacs-exec"pymacs")(autoload'pymacs-load"pymacs")(load (concatpy-install-directory"completion/pycomplete.el")nilt)(add-hook'python-mode-hook'py-complete-initialize))(error"`py-install-directory' not set, see INSTALL"))))(eval-after-load'pymacs'(load-pycomplete));; pyflakes flymake integration;; http://stackoverflow.com/a/1257306/347942(when(load "flymake"t)(defunflymake-pyflakes-init()(let* ((temp-file(flymake-init-create-temp-buffer-copy'flymake-create-temp-inplace))(local-file(file-relative-nametemp-file(file-name-directorybuffer-file-name))))(list "pycheckers"(list local-file))))(add-to-list'flymake-allowed-file-name-masks'("\\.py\\'"flymake-pyflakes-init)))(add-hook'python-mode-hook'flymake-mode);; menu bar is useful when getting started(menu-bar-mode)(setq-defaultdefault-tab-width4)
Step 3: Create a python virtualenv
We’ll keep all the python-side customization in a virtualenv named
default. It’s important that the name you choose is the same as the
name in the (virtualenv-workon) command in line 45 of Step 2.
vinod:~$ mkvirtualenv -p python2 default
After it does its thing, your shell prompt should change, indicating
that your new virtualenv is activated
Step 4: Install Pymacs
Pymacs is a really cool
piece of software that sets up a 2 way communication between Emacs and
Python, allowing you to control Emacs with python commands rather than
elisp commands. It requires a python piece (Pymacs.py) and an Emacs
piece (pymacs.el). Unfortunately, they’re not installable via pip
or package.el, but installation is easy enough.
(default)vinod:~$ mkdir src
(default)vinod:~/src$ cd src
(default)vinod:~/src$ git clone git://github.com/pinard/Pymacs.git
(default)vinod:~/src$ cd Pymacs
# check to make sure tests pass(default)vinod:~/src/Pymacs$ make check
# install it (Be sure you're inside your virtualenv!)(default)vinod:~/src/Pymacs$ make install
# install the emacs extension(default)vinod:~/src/Pymacs$ cp pymacs.el ~/.emacs.d/$USER/
Step 5: Install other python packages
These helper packages are easier to install:
(default)vinod:~$ pip install pyflakes pep8
The pyflakes and pep8 packages check your code as you type using
Emacs’ flymake mode. Now, deactivate your virtualenv.
Step 6: Install pycheckers
Flymake is the part of Emacs that checks your code for errors on the
fly. It calls a shell script called pycheckers, so you need to have
a script by that name in your shell’s PATH. Here’s mine
As I mentioned in my talk, there are multiple Python modes available,
but I recommend using the one named python-mode.el, which is developed
It does periodically get uploaded to
Marmalade, but the
auto-completion using pycomplete doesn’t work well on the version that
is there now (6.0.10), so I recommend that you manually download and
install the latest stable version (6.0.12). I’ll update this post once
a stable working version gets uploaded to
vinod:~$ cd ~/.emacs.d/$USERvinod:~/.emacs.d/vinod$ curl -L https://launchpad.net/python-mode/trunk/6.0.12/+download/python-mode.el-6.0.12.tar.gz | tar xz
Step 8: Test it all out
Launch emacs and open a python file named test.py. Type the following:
Wait at this point. You should see auto-completion of os.path.join
followed shortly by a yellow popup showing documentation of that method.
Hitting return should accept the completion. Then type ( and you
should see the method signature in the minibuffer.
Move the cursor over any letter in join. Hit ‘F1’. A window should
popup with the docstring for os.path.join. Hit ‘F2’. A new window
should be opened with the code for os.path.join. Hit ‘F3’. You’ll be
prompted to enter the name of any python command, and Emacs will show
you the docstring.
Type the string ‘blah’ and hit return. The string should be
highlighted in pink and if you mouseover it, the minibuffer will say
undefined name 'blah'. That’s flymake working for you.
Hit C-c C-c and the buffer should be sent to a Python interpreter and
you’ll be dropped in the REPL after the code has been loaded. Any
errors in the code will be reported.
If all of this works, then CONGRATULATIONS!!! If not, let me know and
I’ll see if I can help debug.
Step 9: Customize
All of this is customizable in hundreds of ways. Try M-x
customize-group RET python-mode RET to see how.
Step 10: How to create a new python project
Whenever you want to create a new Python project, you have do the
Create a new virtualenv
vinod:~$ mkvirtualenv newproject
Install pymacs into that virtualenv
(newproject)vinod:~$ cd ~/src/Pymacs
(newproject)vinod:~/src/Pymacs$ make install
For the most part, this won’t affect much, but if you move from a
Python2 project to a Python3 project, you may have problems. The
workaround is to call M-x pymacs-terminate-services, then M-x
virtualenv-workon to change your virtualenv, and then finally
M-x load-pycomplete to restart pymacs and pycomplete.
Latest stable version of python-mode.el isn’t on Melpa
I’d much prefer to just load python-mode using the built-in Emacs
Pymacs installation is harder than it needs to be
I wish Pymacs could be installed by a 2 step process
pip install Pymacs
M-x package-install RET pymacs RET
Which pycheckers to use?
My script uses pep8 and pyflakes. There are a lot of other options out
there and I do not know which is best. See
for more details.
Not using ropemacs any more
In my talk, I used ropemacs. In this setup, I have decided against it.
I was mostly using it for code-completion and documentation lookup,
but I like pycomplete.el better for those purposes. It’s included in
python-mode and it shows method signatures as you type. Ropemacs does
have other features such as project management (easily jumping to
files in the same project), and refactoring (changing variable names
throughout project). I haven’t used those, so I decided not to install
Project management not included
I haven’t yet decided which package to use for this. I’ll probably try
projectile, but there are many other options, some lightweight
(ropemacs, eproject, pony-mode) and some heavyweight (ecb, CEDET).
I gleaned knowledge from all of the following, in no particular order.
Thanks to @danpoirier and
@gregnewman for testing. I initially
recommended using the master branch of python-mode.el, but now I
recommend using the latest stable release (as of now) which is version
6.0.12 to avoid problems loading Pymacs. There’s a bug on 6.0.12 with
virtualenv-workon that requires you to put a trailing slash after
the name of your virtualenv, so I’ve updated the init.el file above
to account for those changes.
Autocomplete Mode is an
Emacs mode that tries to guess what word you’re typing and provide
auto-completion. Recently, it started failing in simple scenarios.
It can use various ‘sources’ to try to figure out what you’re about to
type. The simplest source is ac-source-dictionary which is a simple
list of words. If you start typing any of those words, it will try to
autocomplete them for you. Normally, you’d put those words in a file,
with each word on a separate line, but for testing purposes, you can
also add them manually using an elisp function. Here’s the test that
failed for me:
So, autocomplete is looking through each one of those sources, trying
to find possible words I might be typing. The third one is called
ac-source-yasnippet, which seems to be where my error is coming
So, I looked into the yasnippet source code and found that, indeed,
there was no function named yas/current-snippet-table. That function
has been renamed to yas--get-snippets-table in version 0.8.0, but
autocomplete is still relying on the old function name. (RANT: Don’t
rename functions that others might be using without providing some
kind of alias, at least temporarily) I looked at the code for
autosnippet on github
and noted that the latest version has been fixed to use the new code,
but it hasn’t yet been released on MELPA. Until it is, the quick
solution is to remove ac-source-yasnippet from ac-sources.
It seems that autocomplete should be more forgiving of errors in any
specific ‘source’, passing it up to use other sources. Alternatively,
it should fail loudly when there’s an error, so that I can know to fix
or remove the offending ‘source’.
I was a huge Apple fan growing up and IBM was Apple’s enemy. Buying an
IBM computer would have been unthinkable.
Well, the unthinkable has happened. Of course IBM doesn’t make laptops
anymore, but their computers live on under the Lenovo name. I am the
proud owner of a new Lenovo Thinkpad
love this computer. It’s an ugly black boxy thing, but it’s light (4
lbs), quiet and speedy. And the keyboard is just pure awesome. That’s
the main reason that I bought the T420S as opposed to the current T430
line. The new line has the chicklet keyboard that is being used on all
laptops these days. The T420 is the last one with the old-fashioned
clicky keyboard, which I love.
I also feel very lucky to get the deal that I got. I bought it from
Lenovo’s Outlet store, which had about
thirty T420s’s in stock when I was shopping. This one was about half
the price of the others, by my estimation. It’s so underpriced that
I’m wondering if I’m missing an obvious flaw, but I don’t see it.
(Please let me know if you do!)
Here’s a comparison between the specs of my computer compared to one
that was available at the Outlet store on October 4th, 2012:
Windows 7 Pro
Windows 7 Home
14” 1600x900 HD+
14” 1600x900 HD+
Intel Centrino Advanced
The RAM is better on the other model, but Windows 7 Professional is an
upgrade on my model. I don’t really understand why mine was so cheap,
but I’m pretty happy about it!
I added another 4G of RAM, moved Windows to a VirtualBox image and
installed Arch Linux with Xmonad. It takes about 10 seconds to get
from the BIOS screen to a working computer. I’ll post some info on my
setup in a future post.
Time for some pop philosophy. I’ve never thought too deeply about the
concept of free will. Of course we have free will! I chose to live my
life a certain way. I could choose to live a different way. It is my
free will to choose how I live. I’ve never thought about it more
deeply than that.
I recently read Walter Isaacson’s biography of Einstein and I was
forced to think more deeply about free will. The biography is
excellent. It gives more depth to Einstein, who, despite his flaws, is
still a heroic figure. One day, I’ll do a proper review, but the piece
that struck me the hardest was Einstein’s views on free will. He
didn’t believe that free will existed, and not only that, he didn’t
even to seem to think that this was a controversial position. It
appears that Isaacson didn’t either, because he didn’t spend much time
on that part of Einstein’s character. But, it seemed so strange to me,
since I assumed that we all have free will.
So, I read Sam Harris’s e-book
Free Will, in which he concisely
explains why free will is a myth. Take any conscious decision that you
might make. Let’s say you choose at this moment to go eat a pizza. Do
you have the free will to make that choice? Well, you certainly can go
eat pizza, but the question is if you had the free will to do it. What
were the steps that led to making that choice. Somewhere in your
brain, a certain set of neurons fired to trigger the idea in your mind
to have a pizza. How did those neurons fire? Either there was a
conscious decision to have that thought, or it was an unconscious
decision that you didn’t control. And if it was a conscious decision,
then you can take that back a step further and ask how that decision
occurred. Eventually, you will have to start at some unconscious (or
subconscious) event which triggered the series of events which
eventually led to your decision to have a pizza. No matter how far
back you can track the conscious trail that led to a pizza forming in
your mind, eventually you are left with an unconscious starting point.
Certainly all of these thoughts are heavily influenced by your life
experiences. If you’ve never seen or heard of a pizza, there’s a zero
percent chance that you’ll think of a eating a pizza. But all of those
life experiences are themselves the result of conscious and
unconscious decisions, all of which we ultimately have no specific
Every thought you have is the only thought you could have at that
moment. It is the result of all of the life experiences and thoughts
that you have had up to that moment. If you consciously try to
“create” an original thought, just to prove that you have free will,
well… you can’t. Because that decision itself originated from
somewhere in your subconscious, and is therefore something that you
don’t have conscious control over.
In addition to this theoretical rationalization against the concept of
free will, Harris describes multiple studies from neuroscience
which show that neurons fire in our subconscious well before we
develop the urge to act. Examples:
Bottom line: I’m convinced that I don’t have the free will that I
thought I did. The question is how this should affect my life. It
could be depressing. If every thought of mine originates in a way that
I don’t control, then am I just being steered through life? It makes
my accomplishments in life seem less “worthy”. On the other hand, it
can be quite freeing. My path through life is determined. Perhaps I
shouldn’t be worrying so much about every decision, because I know
that they’re not really “my” decisions to make. It can also give you
more empathy for others, knowing that they also have no will do
anything but what they are doing.
It’s still a confusing topic, because I “feel” like I have options in
life and I “feel” like taking different options will change my life.
That part is true. The part that isn’t true is that I have any control
over the range of available options, nor over the specific option that
I choose. Even Harris seems to be a little conflicted here:
Losing a belief in free will has not made me fatalistic—in fact, it has increased my feelings of freedom. My hopes, fears, and neuroses seem less personal and indelible. There is no telling how much I might change in the future. Just as one wouldn’t draw a lasting conclusion about oneself on the basis of a brief experience of indigestion, one needn’t do so on the basis of how one has thought or behaved for vast stretches of time in the past. A creative change of inputs to the system—learning new skills, forming new relationships, adopting new habits of attention—may radically transform one’s life.
The question is how do you accomplish a ‘creative change of inputs’,
if you don’t have the will to do so? I guess the idea is that while I
don’t have any control over the thoughts that arise in my brain, I do
have perceived control over my decisions. With whatever power my
conscious brain has, I can choose things that will improve my life,
with the hope that exposure to new experiences will ‘change the
inputs’ to my subconscious brain. Ugh, just thinking about how this
all works makes my brain hurt. I guess this is why I never studied
philosophy before. :-)
Free Will is short and cheap and
I highly recommend it.
