Let's start with exploring the concept of Object-Relation Mapping with what the Ruby on Rails Guides tells us: "[ORM] is a technique that connects the rich objects of an application to tables in a relational database management system". So, in a conventional Rails app, the ORM is Active Record, and the relational database management system (RDBMS) might be something like Postgresql. Rails' Active Record is the design pattern implementation of the eponymous concept espoused by Martin Fowler. This functionality lets us make queries and interac with data from a database the same way we would with objects, hence object-relational mapping.
The significance of ORM is that it maps the objects described and created in an application to tables and rows in the database, providing a level of abstraction from which to interac with the database with. The result of this relationship is "persistence", which enables the storage and retrieval of just such objects. As one can imagine, persistence, the successful storage and retrieval of objects, is pretty important if you want to do anything these days. The Rails Guides succinctly states: "Active Record [the ORM] facilitates the creation and use of business objects whose data requires persistent storage to a database".
One of the benefits of using an ORM like Active Record is that it standardizes the logic used to access a database by abstracting and handling the database logic for us. For example in Rails, an object inheriting from ActiveRecord::Base comes with a myriad of methods that simplifies complex database transactions and assocations. This cuts back on the amount of raw SQL code that needs to be written, streamlining this aspect of the development process.
For example: I run a mailer application on Rails that sends out a random poem every morning (sign up for a poem a day if you like) that has a number of Reader objects. With the help of Active Record, the creation of a Reader object can be as simple as:
Reader.create(name: "Ovid", email<EMAIL_ADDRESS>But if we watch the logs as this happens, Active Record is handling the actual SQL statement for us:
INSERT INTO "readers" ("name", "email", "created_at", "updated_at")
VALUES ($1, $2, $3, $4) RETURNING "id" [["name", "Ovid"], ["email"<EMAIL_ADDRESS>["created_at", "2016-01-06 20:47:56.440566"], ["updated_at", "2016-01-06 20:47:56.440566"]]
What we see here is ORM in action. Active Record maps the class Reader to a table in the database and then inserts a row into the table containing the information of the object created: the name, email, id, timestamps etc.
Without ORM, basic create, read, update, delete, (CRUD) processes would be brittler, messier and more difficult to implement and test. Active Record simplifies database interactions, if one needs basic CRUD utilities or more advanced things, like validations and creating relationship between tables.
For example, two other important things that Active Record handles for us are validations and relationships between tables (assocations). In this next snippet, the Reader model is associated to a Book model through a has_many association provided by Active Record. This association tells us that instances of the Book class will have a foreign key that refers to instances of this Reader class. This is known as a join in SQL parlance. This snippet also displays a number of validation conditions that must be met before the object will be saved to the database. Validations are important because they ensure the integrity of your data is what you expect it to be; the example here ensures one's email address is a valid address with a regex coupled with callback.
class Reader < ActiveRecord::Base
before_save :downcase_email
has_many :books
validates :name, presence: true, length: { maximum: 50 }
VALID_EMAIL_REGEX=/ \A[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i
validates :email, presence: true, length: { maximum: 255 },
format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }
private
def downcase_email
self.email = email.downcase
end
end
In sum, ORM mediates an application's objects, their storage, retrieval, and relationships within a database, allowing us to treat stored data in an object-oriented manner. The Ruby on Rails ORM
Active Record is described to:
"Represent models and their data". We see this when a Class is mapped to a table, and its objects are mapped to rows with columns representing their attributes. Active Record returns representations of these objects to us
when we request them.
"Represent associations between these models". We see this when we perform associations like has_many or belongs_to.
"Represent inheritance hierarchies through related models". I'm not really sure what the difference is between an association and an inheritance hierarchy - I'll write more about this when I get to talking about single table
inheritance in the next few weeks.
"Validate models before they get persisted to the database". We see this when we use validations and callbacks, like validates and before_create.
"Perform database operations in an object-oriented fashion". We see this with the ease we have when performing basic CRUD operations, as well as when access attributes of objects, such as in the case:
puts Reader.name # Ovid

Friday's Best Bet: Catoca can score off the claim at Del Mar
by Jarrod HorakFriday’s 7th race from Del Mar is a starter allowance event for fillies and mares dashing seven furlongs on the main track (Post Time - 6:34 p.m. ET).
Click here for Del Mar Entries & Results
#8 CATOCA (5-2) was nabbed out of her last by Jeff Mullins. She has been performing well in flat mile dirt races this year. Flavien Prat climbs aboard and she might like 7f. She drilled a bullet for this Nov. 6 and earned quality pace ratings in a $35k/3L one mile dirt race at Santa Anita Oct. 18 (2nd by 1/2 length).
#9 Incredibly Lucky (8-1) brings good recent form to the table and drew outside the other speed. She is a bit light on numbers and I am not sure about seven panels, but her best number was at Del Mar Aug. 30.
#3 Claudelle (7-2) exits back-to-back front running romps at Santa Anita. She is 0-for-3 at Del Mar (2 runner-up finishes) and this is her first extended sprint try.
#4 Dearborn (5-1) returns to dirt and stretches out a furlong and a half. She set the pace and finished 2nd in a local flat mile dirt affair vs. this kind July 20. Drayden Van Dyke hops aboard and he always seems to elevate his game at Del Mar.
#7 Mongolian Empire (8-1) easily ran down Dearborn in her lone local try at one mile, and that was her best dirt number to date.
Wagers:
#8 to win

Installing Haxchi
Haxchi is a Wii U exploit which allows you to run Homebrew from your Wii U on versions 5.5.1 and 5.5.2 with an 100% success rate. It does not require you to have internet access. We will later use Haxchi to launch Wii U CFW on boot. We will also install the Homebrew Launcher and the Homebrew App Store, so you can download homebrew easily.
Installing Haxchi
- Download Homebrew Launcher v1.4
- Download the latest release of Haxchi
- Extract the contents of the Haxchi
.zip
to the root of your SD card - Extract the contents of the Homebrew Launcher
.zip
to the root of your SD card - Insert the SD card into your Wii U
- Open the eShop and download one of these games
- We recommend Brain Age, as it's the cheapest
- A pirated copy won't work
- If you own one of these games already, use that
- If you're on 5.5.1 and don't want to update, use nnu-patcher to access the eShop
- Make sure it's installed on your internal storage, not a USB
- Open up the Browser and navigate to cfw.guide/go
- Launch the Haxchi Installer
- Select the DS virtual onsole title you want to install Haxchi on
- Read the warning and then press A to install
- Go back to the Home Menu and launch Haxchi
- If you can't see it or it doesn't work properly, try again
You should now reboot into a patched sysNAND
You can use Haxchi to launch many other homebrews by editing the haxchi/config.txt
file too. The correct format is button=path
, for example: x=wiiu/apps/homebrew_launcher/homebrew_launcher.elf
. This would launch the Homebrew Launcher if the X button is held down while Haxchi is launched.
Installing Homebrew Titles
- Download the latest release of the Homebrew Channel (the channel
.zip
file) - Download WUP Installer GX2
- Download the WUP Installer GX2 Channel
- Download Homebrew App Store v1.5
- Create a new folder in the root of your SD card named
install
- Create a new folder in the
install
namedhbc
- Extract the contents of the Homebrew App Store
.zip
to thewiiu
folder on your SD card - Extract the contents of the WUP Installer GX2
.zip
to the root of your SD card - Extract the contents of the Homebrew Channel
.zip
to theinstall/hbc
folder on your SD card - Extract the
WUP_Installer_GX2
folder from the WUP Installer GX2 Channel.zip
to theinstall
folder on your SD card - Launch the Haxchi title to reboot into a patched sysNAND
- Launch the Haxchi title again, but hold down A while launching it
- Launch WUP Installer GX2
- Select Homebrew Channel > Install > Yes > NAND
- Select WUP Installer GX2 > Install > Yes > NAND
You should now be able to launch the Homebrew Channel and WUP Installer GX2 from your Home Menu. You'll also be able to launch the Homebrew App Store from the Homebrew Channel to download whatever homebrew you want.

At Google I/O 2017, Google announced Android Go, a configuration of Android that is optimized for entry-level devices. The focus of this initiative is around affordability, limited connectivity and multi-lingual capability. Starting Android O, all devices that have a memory of 1GB or less will ship with this configuration.
I see this step as sort of an acknowledgement that we are reaching the limits of “one-size-fits-all” mentality we’ve had all these years. It is a refreshing change from the “We have a potential target of a billion users, hence we must make a single app that caters to all”. Android has reached the tipping point (2 billion active users) where that approach no longer scales. In the best case it results in a solution that satisfies one subset of users at the expense of the other. In the worst case it produces something that does not solve the needs of either!
The requirements and constraints of the developing world are vastly different from that of the developed world. App usage patterns for the same app might differ between the target groups. Localization is about more than translating strings, currency and temperature units. Not all the guidelines about writing style are applicable globally. Metaphors do not scale well across languages and cultures.
Facebook set the ball rolling with the Facebook Lite app. This is a tiny app (<2MB installed size excluding data on my Android 6.0 phone). Compare this with the regular Facebook app that is >70MB at the time of this writing. The Facebook Lite app is also frugal in its mobile data usage.
YouTube Go seems to be following in the footsteps. They have studied and understood how people use YouTube in developing markets.  The peer to peer sharing feature is the killer. Most people were using some shady youtube downloader apps to download YT videos offline, and then sharing it with peers using ShareIt or the like anyway.
I believe Android Go will act as a turning point in the industry’s approach to global apps. It is no longer taboo to offer multiple flavors of the same app, catering to different target groups. In fact, with Android Go’s Google Play catalog that highlights apps optimized for the entry-level devices, I believe this will become a norm going forward.
Remember, it is not about how many users you have, but about how useful your app is to those users.

Hi! I'm pursuing a Master's in Language Technologies from CMU. I'm advised by Prof. Yiming Yang. Before joining CMU, I was a Principal Member of Technical Staff at Oracle. I was fortunate to have Jagdish Chand as my manager at Oracle (and before that at Visa). I moved to the Bay Area in 2015 to work at Visa Inc. after finishing my Master's in Computer Science and Engineering from IIT Bombay. For my thesis, I was advised by Prof. Sunita Sarawagi, Prof. Mausam and Prof. Ganesh on extracting numerical relations from text. More about me: industry experience, projects, cv (slightly outdated), blog (sparsely populated), and stackoverflow profile.I also enjoy hiking, swimming, reading and aimlessly driving while listening to all kinds of music. |


My first assignment with Bryan required me to learn a new trade; for three days, I learned how to paint. And what better is there to learn on than Bryan’s office?
What started out as a dirty (from use) white, is now some-special-name blue (I only know a few color names… they all look the same to me). We’re 98% done, and Bryan is really pleased with how it came out.
I won’t say more, because – seriously – I was painting… there’s just not much more to say than that.

Vos sees no problem recognizing Bible week
MADISON, Wis. - The state Assembly's top Republican says he doesn't see any problem with a resolution that recognizes Thanksgiving week as National Bible Week.
The Assembly is set to vote Tuesday on a resolution that recognizes the week and declares that the reading the Bible has contributed to the moral fiber of society.
Democratic Minority Leader Gordon Hintz told reporters it seems like GOP lawmakers are starting "holy wars" to distract from a lack of a real agenda.
Speaker Robin Vos told reporters the Assembly traditionally recognizes different faiths' holidays and "many of us are Christians."
The vote comes days after Democratic Gov. Tony Evers called the evergreen the state Department of Administration places in the state Capitol every December a holiday tree. Evers' predecessor, Republican Scott Walker, had declared it a Christmas tree.
Vos says it's clearly a Christmas tree. He says Evers is going through "machinations" to please a tiny group of easily offended people.

I find this post, near the bottom, to be very encouraging.
Also, "Know the process"
On April 6th, 2007 Anonymous says:
Like it or not, software development has a lot of process, so you might as well learn to like it, or at least take the time to understand the how's and why's of it. Every young developer should read books and articles on software engineering. Every young developer should be starting to understand the actual cost of development, how to gather and validate requirements, risk managment, ways to improve quality, factors that impact maintenance, etc.
There was a recent slashdot article discussing the fact that those job candidates who cannot code, *really* cannot code: they cannot even code fizzbuzz. Well, the same is true of process knowledge: I frequently reject candidates young and old who are unclear on things like the purpose of a release branch, code coverage, or use cases.
If you don't understand the software development process, you will always be limited to just doing little coding tasks given to you by others who do understand software engineering (or worse, those who do not).


For instructions on the basic make options, go to the top-level enzo directory and type:
gmake help
The compilation process is fairly straightforward. Enzo is already pre-configured to compile on most NCSA, SDSC and PSC machines. While in the top-level directory, type:
./configure
gmake
gmake install
All portions of the code should automatically compile and executables should be placed in the enzo-code/bin directory. If you are compiling on non-NCSA machine you may have to add extra makefiles in the config directory to get the code to compile correctly. See the README in enzo-code/config for more information. If you are using a machine type/architecture that isn't explicitly supported the process of compilation could become extremely complicated.
The general philosophy of enzo is that all options are specified in the parameter file at run-time, so that once the code is compiled it does not need to be recompiled to run another problem or change a parameter. There are some compiler-time parameters, which can be seen by typing:
gmake help-config
This allows the user to specify the specific machine, the desired precision of the code, the version of HDF, and various timing and optimization settings. The code is parallelized using MPI, so compiler-based parallelization is NOT recommended.
There are several subdirectories in the enzo-code directories. They are:
| directory | description |
|---|---|
| bin | binary directory |
| ring | contains the Ring particle IO parallelization tool |
| hdf5_tools | contains various tools that may be useful for the HDF 5 version of enzo |
| amr_mpi | the directory containing source for the enzo code and analysis tools |
| enzo_jobs | example batch files |
| uniglue | tool for putting Enzo HDF 5 datasets together into single monolithic files |
| inits | cosmological initial conditions generator |
| config | Files for configuring enzo |
| enzo_tests | test files and sample parameter files |

Categorical data, where the order of the categories is important, is called Ordinal data. Question 10 of the survey asked the respondents, “How satisfied are you with your local government’s initiatives to address issues present in your community?” It provided the respondents with five non-numeric options: Extremely satisfied, satisfied, Average, Dissatisfied, and Extremely Dissatisfied. Here, the five options create five categories, and there exists a natural ordering between these categories. Hence such data is Ordinal in nature.

Considering my use of Git as a means to track revisions on my own writing, it’s important to note that you should feel free to replace all instances of “software” in the above statement with “words,” “writing,” “expression,” etc.
While I appreciate tremendously the work and contribution of Arlo Bendiken in the form of The Unlicense, I would like to add that I see no need, personally, to make the refutation of Intellectual Property law regarding my own work into some profound ethical statement. As it stands, I have not to my knowledge been the victim of any sort of theft of any kind, and find the suggestion highly unlikely. If I am made aware of such a case, there is certainly a possibility that I may change my mind on this issue, so I suppose I should highlight that THESE TERMS ARE SUBJECT TO CHANGE, though I suspect I would be more flattered and/or amused than actually offended.
I would also like to annotate that my use of this license should not be regarded as a suggestion that anyone else follow my example, or that I “believe in” taking such action regarding one’s work, generally. While I did indeed take the time to set up a repository of John Perry Barlow’s “The Economy of Ideas” in a bunch of different document formats, I do not necessarily agree with all of what he argued, especially in the context of the world 27 years later. If you are particularly interested in my opinion on the matter for whatever reason, here is what I have to say to you:
The principled beginning of The Open Web was a great moment in history, but - like all historical principles - it is extremely important that we consider context and maintain an appropriate level of criticism when looking back on old manifestos written by old white guys. In general, try your best to be reasonable.

Lets Write a Compiler!
Our goal is to write a compiler which is a function:
In 131 TargetProgram
is going to be a binary executable.
Lets write our first Compilers
SourceProgram
will be a sequence of four tiny “languages”
- Numbers
- e.g.
7
,12
,42
…
- Numbers + Increment
- e.g.
add1(7)
,add1(add1(12))
, …
- Numbers + Increment + Decrement
- e.g.
add1(7)
,add1(add1(12))
,sub1(add1(42))
- Numbers + Increment + Decrement + Local Variables
- e.g.
let x = add1(7), y = add1(x) in add1(y)
Recall: What does a Compiler look like?
An input source program is converted to an executable binary in many stages:
- Parsed into a data structure called an Abstract Syntax Tree
- Checked to make sure code is well-formed (and well-typed)
- Simplified into some convenient Intermediate Representation
- Optimized into (equivalent) but faster program
- Generated into assembly
x86
- Linked against a run-time (usually written in C)
Simplified Pipeline
Goal: Compile source into executable that, when run, prints the result of evaluating the source.
Approach: Lets figure out how to write
- A compiler from the input string into assembly,
- A run-time that will let us do the printing.
Next, lets see how to do (1) and (2) using our sequence of adder
languages.
Adder-1
- Numbers
- e.g.
7
,12
,42
…
The “Run-time”
Lets work backwards and start with the run-time.
Here’s what it looks like as a C
program main.c
#include <stdio.h>
extern int our_code() asm("our_code_label");
int main(int argc, char** argv) {
int result = our_code();
printf("%d\n", result);
return 0;
}
main
just callsour_code
and prints its return value,our_code
is (to be) implemented in assembly,- Starting at label
our_code_label
, - With the desired return value stored in register
EAX
- per, the
C
calling convention
- Starting at label
Test Systems in Isolation
Key idea in SW-Engg:
Decouple systems so you can test one component without (even implementing) another.
Lets test our “run-time” without even building the compiler.
Testing the Runtime: A Really Simple Example
Given a SourceProgram
42
We want to compile the above into an assembly file forty_two.s
that looks like:
For now, lets just
- write that file by hand, and test to ensure
- object-generation and then
- linking works
On a Mac use -f macho
instead of -f aout
We can now run it:
Hooray!
The “Compiler”
Recall, that compilers were invented to avoid writing assembly by hand
First Step: Types
To go from source to assembly, we must do:
Our first step will be to model the problem domain using types.
Lets create types that represent each intermediate value:
Text
for the raw input sourceExpr
for the ASTAsm
for the output x86 assembly
Defining the Types: Text
Text
is raw strings, i.e. sequences of characters
texts :: [Text]
texts =
[ "It was a dark and stormy night..."
, "I wanna hold your hand..."
, "12"
]
Defining the Types: Expr
We convert the Text
into a tree-structure defined by the datatype
Note: As we add features to our language, we will keep adding cases to Expr
.
Defining the Types: Asm
Lets also do this gradually as the x86 instruction set is HUGE!
Recall, we need to represent
An Asm
program is a list of instructions each of which can:
- Create a
Label
, or - Move a
Arg
into aRegister
Return
back to the run-time.
Where we have
Second Step: Transforms
Ok, now we just need to write the functions:
parse :: Text -> Expr -- 1. Transform source-string into AST
compile :: Expr -> Asm -- 2. Transform AST into assembly
asm :: Asm -> Text -- 3. Transform assembly into output-string
Pretty straightforward:
parse :: Text -> Expr
parse = parseWith expr
where
expr = integer
compile :: Expr -> Asm
compile (Number n) =
[ IMov (Reg EAX) (Const n)
, IRet
]
asm :: Asm -> Text
asm is = L.intercalate "\n" [instr i | i <- is]
Where instr
is a Text
representation of each Instruction
instr :: Instruction -> Text
instr (IMov a1 a2) = printf "mov %s, %s" (arg a1) (arg a2)
arg :: Arg -> Text
arg (Const n) = printf "%d" n
arg (Reg r) = reg r
reg :: Register -> Text
reg EAX = "eax"
Brief digression: Typeclasses
Note that above we have four separate functions that crunch different types to the Text
representation of x86 assembly:
Remembering names is hard.
We can write an overloaded function, and let the compiler figure out the correct implementation from the type, using Typeclasses.
The following defines an interface for all those types a
that can be converted to x86 assembly:
class ToX86 a where
asm :: a -> Text
Now, to overload, we say that each of the types Asm
, Instruction
, Arg
and Register
implements or has an instance of ToX86
instance ToX86 Asm where
asm is = L.intercalate "\n" [asm i | i <- is]
instance ToX86 Instruction where
asm (IMov a1 a2) = printf "mov %s, %s" (asm a1) (asm a2)
instance ToX86 Arg where
asm (Const n) = printf "%d" n
arg (Reg r) = asm r
instance ToX86 Register where
asm EAX = "eax"
Note in each case above, the compiler figures out the correct implementation, from the types…
Adder-2
Well that was easy! Lets beef up the language!
- Numbers + Increment
- e.g.
add1(7)
,add1(add1(12))
, …
Repeat our Recipe
- Build intuition with examples,
- Model problem with types,
- Implement compiler via type-transforming-functions,
- Validate compiler via tests.
1. Examples
First, lets look at some examples.
Example 1
How should we compile?
add1(7)
In English
- Move
7
into theeax
register - Add
1
to the contents ofeax
In ASM
Aha, note that add
is a new kind of Instruction
Example 2
How should we compile
add1(add1(12))
In English
- Move
12
into theeax
register - Add
1
to the contents ofeax
- Add
1
to the contents ofeax
In ASM
Compositional Code Generation
Note correspondence between sub-expressions of source and assembly
We will write compiler in compositional manner
- Generating
Asm
for each sub-expression (AST subtree) independently, - Generating
Asm
for super-expression, assuming the value of sub-expression is inEAX
2. Types
Next, lets extend the types to incorporate new language features
Extend Type for Source and Assembly
Source Expressions
Assembly Instructions
Examples Revisited
src2 = "add1(add1(12))"
exp2 = Add1 (Add1 (Number 12))
asm2 = [ IMov (EAX) (Const 7)
, IAdd (EAX) (Const 1)
]
3. Transforms
Now lets go back and suitably extend the transforms:
parse :: Text -> Expr -- 1. Transform source-string into AST
compile :: Expr -> Asm -- 2. Transform AST into assembly
asm :: Asm -> Text -- 3. Transform assembly into output-string
Lets do the easy bits first, namely parse
and asm
Parse
parse :: Text -> Expr
parse = parseWith expr
expr :: Parser Expr
expr = try primExpr
<|> integer
primExpr :: Parser Expr
primExpr = Add1 <$> rWord "add1" *> parens expr
Asm
To update asm
just need to handle case for IAdd
instance ToX86 Instruction where
asm (IMov a1 a2) = printf "mov %s, %s" (asm a1) (asm a2)
asm (IAdd a1 a2) = printf "add %s, %s" (asm a1) (asm a2)
Note
- GHC will tell you exactly which functions need to be extended (Types, FTW!)
- We will not discuss
parse
andasm
any more…
Compile
Finally, the key step is
compile :: Expr -> Asm
compile (Number n)
= [ IMov (Reg EAX) (Const n)
, IRet
]
compile (Add1 e)
= compile e -- EAX holds value of result of `e` ...
++ [ IAdd (Reg EAX) (Const 1) ] -- ... so just increment it.
Examples Revisited
Lets check that compile behaves as desired:
ghci> (compile (Number 12)
[ IMov (Reg EAX) (Const 12) ]
ghci> compile (Add1 (Number 12))
[ IMov (Reg EAX) (Const 12)
, IAdd (Reg EAX) (Const 1)
]
ghci> compile (Add1 (Add1 (Number 12)))
[ IMov (Reg EAX) (Const 12)
, IAdd (Reg EAX) (Const 1)
, IAdd (Reg EAX) (Const 1)
]
Adder-3
You do it!
- Numbers + Increment + Double
- e.g.
add1(7)
,twice(add1(12))
,twice(twice(add1(42)))
Adder-4
- Numbers + Increment + Decrement + Local Variables
- e.g.
let x = add1(7), y = add1(x) in add1(y)
Local Variables
Local variables make things more interesting
Repeat our Recipe
- Build intuition with examples,
- Model problem with types,
- Implement compiler via type-transforming-functions,
- Validate compiler via tests.
Step 1: Examples
Lets look at some examples
Example: let1
Need to store 1 variable – x
Example: let2
Need to store 3 variable – x, y, z
Example: let3
Need to store 3 variables – a
, b
, c
– but at most 2 at a time
- First
a, b
, thena, c
- Don’t need
b
andc
simultaneously
Registers are Not Enough
A single register eax
is useless:
- May need 2 or 3 or 4 or 5 … values.
There is only a fixed number (say, N
) of registers:
- And our programs may need to store more than
N
values, so - Need to dig for more storage space!
Memory: Code, Globals, Heap and Stack
Here’s what the memory – i.e. storage – looks like:
Focusing on “The Stack”
Lets zoom into the stack region, which when we start looks like this:
The stack grows downward (i.e. to smaller addresses)
We have lots of 4-byte slots on the stack at offsets from the “stack pointer” at addresses:
[EBP - 4 * 1]
,[EBP - 4 * 2]
, …,
How to compute mapping from variables to slots ?
The i
-th stack-variable lives at address [EBP - 4 * i]
Required A mapping
- From source variables (
x
,y
,z
…) - To stack positions (
1
,2
,3
…)
Solution The structure of the let
s is stack-like too…
- Maintain an
Env
that mapsId |-> StackPosition
let x = e1 in e2
addsx |-> i
toEnv
- where
i
is current height of stack.
- where
Example: Let-bindings and Stacks
let x = 1 -- []
, y = add1(x) -- [x |-> 1]
, z = add1(y) -- [y |-> 2, x |-> 1]
in
add1(z) -- [z |- 3, y |-> 2, x |-> 1]
QUIZ
At what position on the stack do we store variable c
?
-- []
let a = 1 -- [a |-> 1]
, c = -- [a |-> 1]
let b = add1(a) -- [b |-> 2, a |-> 1]
in add1(b) -- [a |-> 1]
-- [c |-> 2, a |-> 1]
in
add1(c)
A. 1 B. 2 C. 3 D. 4 E. not on stack!
haskell "ENVIRONMENT" -- [] let a = 1 -- [a |-> 1] , b = 2 -- [b |-> 2, a |-> 1] , c = -- let b = add1(a) -- [b |-> 3, b -> 2, a |-> 1] in add1(b) -- -- [b |-> 2, a |-> 1] in add1(b)
Strategy
At each point, we have env
that maps (previously defined) Id
to StackPosition
Variable Use
To compile x
given env
- Move
[ebp - 4 * i]
intoeax
(where env
maps x |-> i
)
Variable Definition
To compile let x = e1 in e2
we
- Compile
e1
usingenv
(i.e. resulting value will be stored ineax
) - Move
eax
into[ebp - 4 * i]
- Compile
e2
usingenv'
(where env'
be env
with x |-> i
i.e. push x
onto env
at position i
)
Example: Let-bindings to Asm
Lets see how our strategy works by example:
Example: let1
QUIZ: let2
When we compile
The assembly looks like
mov eax, 10 ; LHS of let x = 10
mov [ebp - 4*1], eax ; save x on the stack
mov eax, [ebp - 4*1] ; LHS of , y = add1(x)
add eax, 1 ; ""
???
add eax, 1
What .asm instructions shall we fill in for ???
mov [ebp - 4 * 1], eax ; A
mov eax, [ebp - 4 * 1]
mov [ebp - 4 * 1], eax ; B
mov [ebp - 4 * 2], eax ; C
mov [ebp - 4 * 2], eax ; D
mov eax, [ebp - 4 * 2]
; E (empty! no instructions)
Example: let3
Lets compile
Lets figure out what the assembly looks like!
Step 2: Types
Now, we’re ready to move to the implementation!
Lets extend the types for Source Expressions
type Id = Text
data Expr = ...
| Let Id Expr Expr -- `let x = e1 in e2` modeled as is `Let x e1 e2`
| Var Id
Lets enrich the Instruction
to include the register-offset [ebp - 4*i]
Environments
Lets create a new Env
type to track stack-positions of variables
data Env = [(Id, Int)]
data Maybe a = Nothing | Just a
lookupEnv :: Env -> Id -> Maybe Int
lookupEnv [] x = Nothing
lookupEnv ((y, n) : rest) x = if x == y
then Just n
else lookupEnv rest x
pushEnv :: Env -> Id -> (Int, Env)
pushEnv env x = (xn , env')
where
env' = (x, xn) : env

[IMov (RegOffset EBP xn) EAX ]
++
compile env' e2
where
(xn, env') = pushEnv env x
compile env (Var x) = [IMov EAX (RegOffset EBP xn)]
where
xn = case lookupEnv env x of
Just n -> n
Nothing -> error "variable out of scope"
API:
- Push variable onto
Env
(returning its position), - Lookup variable’s position in
Env
push :: Id -> Env -> (Int, Env)
push x env = (i, (x, i) : env)
where
i = 1 + length env
lookup :: Id -> Env -> Maybe Int
lookup x [] = Nothing
lookup x ((y, i) : env)
| x == y = Just i
| otherwise = lookup x env
Step 3: Transforms
Ok, now we’re almost done. Just add the code formalizing the above strategy
Code
Variable Use
compileEnv env (Var x) = [ IMov (Reg EAX) (RegOffset EBP i) ]
where
i = fromMaybe err (lookup x env)
err = error (printf "Error: Variable '%s' is unbound" x)
Variable Definition
compileEnv env (Let x e1 e2 l) = compileEnv env e1
++ IMov (RegOffset EBP i) (Reg EAX)
: compileEnv env' e2
where
(i, env') = pushEnv x env
Step 4: Tests
Lets take our adder
compiler out for a spin!
Recap: We just wrote our first Compilers
SourceProgram
will be a sequence of four tiny “languages”
- Numbers
- e.g.
7
,12
,42
…
- Numbers + Increment
- e.g.
add1(7)
,add1(add1(12))
, …
- Numbers + Increment + Decrement
- e.g.
add1(7)
,add1(add1(12))
,sub1(add1(42))
- Numbers + Increment + Decrement + Local Variables
- e.g.
let x = add1(7), y = add1(x) in add1(y)
Using a Recipe
- Build intuition with examples,
- Model problem with types,
- Implement compiler via type-transforming-functions,
- Validate compiler via tests.
Will iterate on this till we have a pretty kick-ass language.

This will be a description of my first time with 5-MeO-MIPT. I have previously had experience with LSD, MDMA, 2C-I, Mushroom, and Ketamine. I tend to have a higher threshold for drugs than most, so that's something to keep in mind. Finally, I was not currently on any other drugs during my trip.
It was later in the night when I dosed myself, around 11pm. Dosing was 10mg previously weighed out on a scale and put into a single gel cap. I had just eaten dinner so I was on a full stomach and had decided to just stay in my apartment for the duration since this was my first time on the drug. I was really looking forward to what was to come after reading about various experiences and hearing from some friends that had taken in previously.
At T-0:45 I began to feel a slight body buzz. It was nothing uncomfortable and felt like the beginnings of a come up on MDMA or acid for me. It was slight but noticeable. Just five minutes later the feeling was much increased. I began feeling very warm and was having a rush of energy. There was also a very strong feeling of muscle tension throughout my body, particularly my arms. It was far more powerful on 5-MeO-MIPT than I have felt on any drug. It was just shy of uncomfortable for me and would persist more or less for the rest of the trip. Fortunately, I did not experience any nausea from this drug as some people do.
At T-1:10 I began to see some slight visualizations. The popcorn ceiling of my apartment was having some waviness to it but never approached the visuals of an LSD or a 2C-I trip. While the visuals were a bit less than I was wanting the increased tactile sensations were great. I was barefoot and walking on my carpet and it felt very 'squishy.' Textures also felt very good, akin to MDMA.
Overall, my trip felt something more in line with a MDMA trip than a normal psychedelic. I had the increased energy and tactile sensations I have had from MDMA, but with far less of the feeling of openness and the wanting to be social. I also felt the 'sexually interesting' effect of this drug. Sex is nothing short of amazing on this drug. My girlfriend had also dosed at the same time as me and we decided to take advantage. Orgasms are intensified and it seemed there was less of a refractory period for me while on this drug. One downside was that at times things felt too intense for my girlfriend. 5-MeO-MIPT also increased my appreciation for music. I played some psytrance and dubstep during my trip and both clicked well with this drug.
Around somewhere around T-4:30 I began to notice the start of a gradual comedown. My muscles began to relax and unwind while the rush of energy I had declined. There wasn't a real crash but rather a gentle, constant comedown. I noticed the return of the wavy visuals this time which I found unusual. There was also some patterning when I looked at the wood grain floor of my bathroom. I had some slight trouble getting to sleep though I think some of the reason for this was the excitement for having such a positive trip on a new drug. It's now the morning and I was able to get a few hours of sleep and feel fine, with no hangover.
A few closing thoughts: I absolutely had a great experience with this drug. I was hoping for some more visuals but I'm guessing I would require a higher dose. The other effects were great and I can't wait to experiment more with this substance.

Well that piece of psychology certainly worked. Stewart Hall's ploy of putting just about the whole squad on the transfer list backfired badly as we lost only our second league game of the season to lowly Rothwell (1-3 - scorer Wright).
I think that really is it for any chance of promotion as we're left miles behind in 9th place.

Together with GtkSocket, GtkPlug provides the ability to embed widgets from one process into another process in a fashion that is transparent to the user. One process creates a GtkSocket widget and passes the ID of that widget’s window to the other process, which then creates a GtkPlug with that window ID. Any widgets contained in the GtkPlug then will appear inside the first application’s window.
The communication between a GtkSocket and a GtkPlug follows the XEmbed Protocol. This protocol has also been implemented in other toolkits, e.g. Qt, allowing the same level of integration when embedding a Qt widget in GTK+ or vice versa.
The GtkPlug and GtkSocket widgets are only available when GTK+
is compiled for the X11 platform and GDK_WINDOWING_X11
is defined.
They can only be used on a GdkX11Display. To use GtkPlug and
GtkSocket, you need to include the gtk/gtkx.h
header.
void gtk_plug_construct (GtkPlug *plug
,Window socket_id
);
Finish the initialization of plug
for a given GtkSocket identified by
socket_id
. This function will generally only be used by classes deriving from GtkPlug.
void gtk_plug_construct_for_display (GtkPlug *plug
,GdkDisplay *display
,Window socket_id
);
Finish the initialization of plug
for a given GtkSocket identified by
socket_id
which is currently displayed on display
.

VIRUS Reviewed by Jamie Peck
Given the set-up, "Virus" sounds like yet another "Aliens" rip-off with a germ of an interesting idea thrown in for good measure. But what's an "Aliens" rip-off without a rag-tag team of assorted grunts and mercenaries to stop by this floating haunted house to infiltrate and investigate? "Virus"' comes in the form of high-seas scavengers who have just lost the barge they were tugging back to a presumable net gain. When the Irish cap'n (hammy Donald Sutherland, sounding like he got his accent inside a Lucky Charms box) and his motley crew spy the evil-infested boat, it's salvage salvation. Silly mortals.
Starting here, the movie adheres to strict genre predictability. A lone survivor (Polish actress Joanna Pacula, very good here) is discovered and provides requisite plot exposition. People venture into dark corridors armed only with flashlights and never return. Sutherland's navigator, played by Jamie Lee Curtis, gets her Sigourney Weaver mojo workin' and guides the good guys in an attempt to kick interplanetary butt.  It's a good thing director John Bruno is a skilled special effects craftsman, because "Virus"' technical terrors offer eye-popping amusement even when the story takes frequent naps from creativity.
Like its own creepy creatures, "Virus" ends up cobbled together out of bits and pieces from similarly-themed fright flicks.  Curtis is also a fun heroine to have on your side (especially when she's in "Halloween" go-girl mode) but the manner in which she finally books it to safety is best described as plot-convenient.
The likeable William Baldwin tags along as a swarthy engineer and Curtis' leading man, but there's no time for romance; their sole intention is survival. But what about the film's intentions? If you crave science-fiction, don't mind story holes, logic lapses and genre copy-catting and have 90 minutes to burn - the movie is pretty well-paced despite its ultimately squandered potential - then this "Virus" is worth catching. Everyone else, however, is better off staying in bed, drinking lots of fluids and popping some antibiotics.

Swimming is a great workout because you need to move your whole body against the resistance of the water. Swimming is a good all-round activity because it: keeps your heart rate up but takes some of the impact stress off your body. builds endurance, muscle strength and cardiovascular fitness.
Swimmer Michael Phelps is one of the greatest Olympic athletes of all time. He has won 18 gold medals in his career. That's more than any other Olympian. Michael Phelps also won more gold medals in one Olympics, eight in 2008, than any other Olympian in history.

This page explains the small example in file examples/rara.cpp.
The program rara.cpp accepts the following command line arguments (in fixed order)
examples/rara data-dir query-conditions [column-to-print [column-to-print ...]]For example, after running 'make check', one can issue the following command
examples/rara tests/tmp/t1 "c between 10 and 20"and see the following output
SELECT count(*) FROM tests/tmp/t1 WHERE c between 10 and 20 --> 22The next command
examples/rara tests/tmp/t1 "c between 10 and 20" cproduces the following output
SELECT c FROM tests/tmp/t1 WHERE c between 10 and 20 --> c (with counts) 10, 2 11, 2 12, 2 13, 2 14, 2 15, 2 16, 2 17, 2 18, 2 19, 2 20, 2
// construct a data partition from the given data directory. ibis::part apart(argv[1], static_cast<const char*>(0));This statement creates an ibis::part object that encapsulates a data partition. The second nil pointer is required because there is another constructor that takes a single string but performs a very different function.
// create a query object with the current user name. ibis::query aquery(ibis::util::userName(), &apart);This statement creates an ibis::query object which represent our query. A FastBit query is always associated with a data partition.
// assign the query conditions as the where clause. int ierr = aquery.setWhereClause(argv[2]);A query object is required to have a where clause (query conditions) before being evaluated. This function returns 0 to indicate success and a negative number to indicate error. This is often the case when an integer is returned from a FastBit function.
ierr = aquery.setSelectClause(sel.c_str());If any column to print is specified on the command line, they are concatenated together into a single string (named sel in rara.cpp). The pointer to the characters is passed to setSelectClause to be recorded as a part of the query.
ierr = aquery.evaluate(); // evaluate the queryThe primary function to evaluate a query is ibis::query::evaluate. This function evaluate the query conditions and identify the records that satisfy the conditions. In some cases, it may be faster to use ibis::query::estimate to get an approximate answer first.
std::cout << aquery.getNumHits();After the function ibis::query::evalaute is called, one may find out how many records satisfy the query conditions by calling ibis::query::getNumHits.
aquery.printSelected(std::cout);If a select clause was successfully set, the function ibis::query::printSelected will print the columns of the selected records to standard output.
The file examples/rara.cpp contains additional code for error checking and optional command-line arguments. The Doxygen documentation of the file is available on-line.
