ESPN’s Prediction For Chiefs-Chargers Tonight
by Tzvi MachlinThe NFL heads to Estadio Azteca in Mexico City tonight as the Kansas City Chiefs take on the Los Angeles Chargers on Monday Night Football. It’s only the third time ever that a game is being played in Mexico, and it should be a good one.
Kansas City comes into this game with a narrow edge over the Oakland Raiders in the AFC West. If they want to avoid giving Oakland the lead and playing catchup, they’ll need reigning NFL MVP Patrick Mahomes at his very best.
Standing in their way are the 4-6 Los Angeles Chargers, who have almost played every game close this season. Two of their wins and all six of their losses have been decided by a touchdown or less. A Chargers win would put them within one game of the AFC West heading into their bye.
ESPN’s computer model has released its prediction for the Chiefs-Chargers game.
ESPN’s computer model believes that Kansas City should win the game. The computer model gives the Chiefs a 73.5-percent chance to win tonight’s game.
Last year, the two teams played a pair of high-octane games, scoring 122 points and 16 touchdowns over eight quarters. With the bright lights of Mexico City on, we can probably expect more of the same this year.
The game will be played at 8:15 p.m. EST on ESPN.

This chapter introduces using Python on Windows. Rather than describe how to use Python on Windows, we discuss the architecture and briefly cover some of the extension modules available.
When you install the Python binaries for Windows, you install a fully functional version of Python that runs under Windows. This version of Python is similar to what you would find on any installation of Python, regardless of the platform, and we begin by briefly discussing how to take full advantage of the standard Python on Windows.
Although this standard version of Python is fully functional, you don't obtain much Windows-specific functionality. To fill the gap, there is a standard set of extensions for Python known collectively as the Python for Windows extensions. These extensions provide access to many Windows-specific features, such as a GUI and IDE environment, Microsoft's COM, the raw Win32 API, Windows NT-specific features, and so forth. We assume you have already installed the Python for Windows extensions, so these extensions are covered in detail. As discussed in Chapter 1, you can find the latest official version of these extensions at http://www.python.org/windows (look for the Windows 95/NT-specific extensions entry).
To complete the picture, we also discuss some other extension modules available for Python on Windows. Many of these are not Windows-specific, but do support Windows, so they are worthy of discussion. Extensions falling into this category include OpenGL, mxTools, Zope, PIL, and others.

Unemployment to fall below 5% but economist warns more needs to be done
by By Geoff PercivalThe national unemployment rate is still on course to fall below 5% next year, assuming a hard Brexit is avoided, but numerous issues need to be addressed in the labour market for it to truly thrive, one economist has warned.
Latest CSO figures show unemployment fell to 4.8% in October, down from 4.9% in September, and from 5.7% in October of last year.
“While on the surface the Irish labour market looks healthy, there are a lot of faults that need to be mended,” said independent economist Alan McQuaid.
The CSO figures show a marginal increase — to 12.3% — in the youth unemployment rate last month.
“There is clearly a problem about the number of jobs available for school leavers and new graduates from college, and the appalling treatment of these students by potential employers.
“There should be more encouragement, in second-level, for students to take apprenticeships and away from the overcrowded university system,” said Mr McQuaid.
He also pointed to unequal pay for female workers and the issue of the mental wellbeing of employees as areas of the labour market that need more attention.
Chambers Ireland welcomed the headline CSO data, but has urged better use of the National Training Fund to focus on in-work training to help companies address emerging skills gaps.
“As we approach full employment we must be mindful of the challenges of such a tight labour market. It’s increasingly challenging for many businesses to find and retain talent leading to increased skills gaps and higher labour costs,” said Chambers CEO Ian Talbot.


After talking about the release of PCIs recommendations for containers and container orchestration environments, and how it could be applied to Kubernetes clusters in my last blog I thought that it might be a good idea to discuss some of the general challenges that assessors and auditors might have when looking at Kubernetes environments, as there’s quite a few variables that you need to account for. This is part of a longer series on the PCI guidance for containers, and an index of the posts in this series can be found here.
What is Kubernetes?
Whilst there is the open source project that’s not how most companies will deploy Kubernetes, instead they’ll make use of a “Kubernetes distribution”. To be a certified Kubernetes distribution software has to pass conformance testing which ensures that it will operate as expected, so there will be a level of common functionality to all Kubernetes distributions. However, there is still a lot of latitude that distribution providers have in terms of the exact configuration and operating model, which an auditor needs to be aware of. At the moment there are 65 different certified distributions 51 different certified “hosted” Kubernetes and 23 different certified installers.
Managed against Unmanaged
Fundamentally there are two different groups of Kubernetes distributions. A managed distribution occurs where the provider manages the control plane (API Server, Controller manager, scheduler and etcd) and the customer has access to, and manages the workloads that run on the cluster (and possibly manages the worker nodes). Major examples of this kind of approach are Amazon EKS, Azure AKS and Google’s GKE.
In a managed installation typically there is no access to look at the configuration of the control plane. This means that from an audit perspective any requirements that relate to precise configuration of the control plane components (for example flags set on the API server) will either be assessed via the provider’s control panels/APIs or in some cases they can’t be directly assessed at all! For some managed distributions there is a CIS benchmark, but if not an auditor will need to look at each requirement to see what the cloud providers defaults are.
In an unmanaged distribution (e.g. Kubeadm, Rancher), the cluster operator typically has full access to the control plane and can configure any of the components as needed. From an auditing perspective this is easier as everything can be assessed. However there is a general challenge in that things like exact file locations and names are not prescribed by the Kubernetes conformance testing, so you can’t assume that things will always be in the same place.
I’ll also call out at this point Red Hat Openshift as it’s kind of a special case. It is a certified Kubernetes but it varies more from core Kubernetes in how it operates, so ideally when assessing it (either in managed or unmanaged form) guidelines being followed should be specifically designed for OpenShift. There is a CIS benchmark for it, so that may be useful.
Kubernetes Versions
Another variable that needs to be accounted for when assessing a Kubernetes cluster is the version of Kubernetes in use. Kubernetes used to release a new version every 3 months and now does so every 4 months. Whilst only the last 3 versions are in support, many clusters are now running unsupported versions so there is a requirement to know about a variety of versions.
One reason why this is important is that the Kubernetes project will introduce new configuration options and deprecate others from version to version. One good example is the “Insecure API port”. This setting went through a process of deprecation over a large number of versions. Initially it defaulted to being available over <IP_ADDRESS>:8080
the default then changed to not being on by default, but still available, to not being available but the flag was still present, to not being available at all. Obviously if you use an audit guide for the wrong version of Kubernetes this could lead to a false positive or false negative result.
Another variable that changes over time with Kubernetes is that API versions change. Basically an API can be in “alpha” (not enabled by default), “beta” (which used to be enabled by default but since Kubernetes 1.24 new beta APIs will not be), “GA” always enabled, “deprecated” shouldn’t be used but still works or removed where it no longer works. One API which is relevant to auditors, which went through some of this process is PodSecurityPolicy, which was a core feature of Kubernetes security for some versions. Its path was alpha–>beta–>deprecated–>removed, but as beta APIs were generally enabled, it was in use by a large number of clusters.
The overall gist of this section is to emphasise the importance of matching the guidance/audit standard you’re using to the version of Kubernetes you’re reviewing. Older guides will often lead to incorrect results as defaults change over time. There are some benchmarks (like the CIS benchmarks) which have different benchmarks for different versions of Kubernetes, but in general this will require reviewers to dig into Kubernetes documentation (and sometimes github issues) to find out what the correct settings are.
Conclusion
The goal of this post was really just to describe some of the complexities that you need to be aware of when assessing or auditing a Kubernetes cluster, it’s important not to take a “one size fits all” approach and to tailor the review to the distribution and version that’s being assessed. I’d expect that over time more assessment guides will be made available. Also I’d expect we’ll see more automated tooling which can help with compliance reviews, however it’s important to note that automated tools have to try and deal with all this complexity as well and some of the requirements in the PCI recommendations do not lend themselves to full automation.
Also whilst there are challenges in the precise detail of assessing Kubernetes cluster, that doesn’t mean we can’t come up with general guidance for the PCI Container Orchestration Recommendations and in the next post(s) I’ll take a look at that topic, starting with the Authentication section


May 2019 - Present
As a part of my graduate studies at the Georgia Institute of Technology, I worked in a graduate research team advised by Professor Ashok Goel in building a knowledge-based AI agent tasked with assisting first-time startup founders with improvements to their business model canvas. The agent, Errol, takes in the user's business model canvas (BMC) and asks the user questions regarding segments of the BMC. These questions are geared towards improvements for the Customer Segment and Value Proposition sections.
The agent initially had a simple HTML/CSS/JS front end, with an a simple natural language processing algorithm consisting of keyword parsing and lexical analysis on input phrases to obtain the meanings. Errol would then run a rule-based advice output system; certain rules were triggered based on certain keywords in the input phrases, and recommendations were generated based on a cosine similarity between input keywords and a populated knowledge-base of advice for the user.
After a round of user testing in May 2019, we observed that the agent needed a serious redesign, both frontend and backend. Below is a brief overview of those changes.
I joined the Errol team in May 2019, and after some qualitative user testing with a low fidelity interface, we were seeing some patterns in user responses. Users had observed that the user interface came off to users as "incomplete" and "simple". Users also mentioned that the interface seemed "like something from the early 2000's."
With regards to the suggestion-output functionality, users noted that certain output phrases were contradictory, and that other phrases were not accurate to the user's inputs. Users also mentioned that the outputs seemed croweded, and that it was hard to distinguish which suggestions corresponeded to which segment (Customers or Values).
This led to us forming redesign goals. Working with another student, Mukundan Kuthalam, we planned to redesign both the interface as well as the backend algorithm for question parsing and phrase outputing.
I began my frontend redesign by quickly whiteboard-sketching possible designs that might help to give our users a more "professional" and "complete" feel of Errol, as they had suggested in user interviews. This led me to pursue designs for a complete dashboard, rather than a single page of inputs and outputs.
To further help with the feeling of "completeness" as users had craved, I sketched a storyboard to show the flow of the many pages we would need to implement, which included a login/signup, our main dashboard, and a user settings page. I added the login and signup feature not only for completeness purposes, but also to plan for future user testing; the Errol agent is built around helping multiple startup teams, and so personalized user accounts would be critical in helping teams keep track of their individual business models and progress through Errol.
The design of the dashboard was meant to convey a feeling of professionalism. After all, we were geared towards helping early stage businesses improve their business models. I made sure to maintain the Customer Segment and Value Proposition fields, as these were our primary segments for outputing suggestions to the user. After inputs were entered, suggestions would be formed through the backend algorithm and displayed below.
The user input processing is handled using the NLTK Python library to analyze the user input statements for parts of speech. First a rule-table is used to handle edge conditions of the user input (ie. not enough information given by the user, user-given descriptions are not specific enough, etc.). If rules in this table are triggered, a series of hard-coded questions are generated and displayed to the user, either asking for more information or for a rephrase of the input statement. See below:
Assuming none of the edge-case rules are hit, the NLTK library is then used to scan the parts of speech in the user input phrases. The keywords, subjects, and objects are parsed from the input phrases, and queries are run to our knowledgebase to retrieve related concepts and actions.
For our knowledgebase, we use ConceptNet, which is an open-source ontology with an external API, allowing us to query for keywords from our users' inputs. The result of the query is a list of related concepts and their meanings, which then allow us to formulate meaningful responses to the users' inputs in the form of our own questions.
Below is an example of some sample questions that may be generated for a user-inputs containing keyword "nurses":
Currently, the Errol redesign is still in progress. However, you can see the work that was done along with other students in Georgia Tech's Design and Intelligence Lab advised by Professor Ashok Goel.
You can also visit the whitepaper published in 2020 regarding the team's progress here: Paper link
Stay tuned for more updates in the near future!

I concentrate on recent advances in techniques related to simultaneous localization and mapping (SLAM). My researches include:
1) fast SLAM for VR/AR on mobile devices (with external supports), e.g., ROSAC,
2) robust SLAM in complex environments, e.g., LOOF,
3) collaborative SLAM based on multiple sensors and multiple unmanned systems.
My goal is to enable fast, robust, and accurate SLAM techniques on various hardware platforms, with the help from modern devices like GPU and ARM and state-of-the-art approaches like deep neural network.

BOA: Branches and Binary Operators
Next, lets add
- Branches (
if
-expressions) - Binary Operators (
+
,-
, etc.)
In the process of doing so, we will learn about
- Intermediate Forms
- Normalization
Branches
Lets start first with branches (conditionals).
We will stick to our recipe of:
- Build intuition with examples,
- Model problem with types,
- Implement with type-transforming-functions,
- Validate with tests.
Examples
First, lets look at some examples of what we mean by branches.
- For now, lets treat
0
as “false” and non-zero as “true”
Example: If1
if 10:
22
else:
0) sub1(
- Since
10
is not0
we evaluate the “then” case to get22
Example: If2
if sub(1):
22
else:
0) sub1(
- Since
sub(1)
is0
we evaluate the “else” case to get-1
QUIZ: If3
if-else
is also an expression so we can nest them:
What should the following evaluate to?
let x = if sub(1):
22
else:
0)
sub1(in
if x:
add1(x)else:
999
- A.
999
- B.
0
- C.
1
- D.
1000
- E.
-1
Control Flow in Assembly
To compile branches, we will use labels, comparisons and jumps
Labels
our_code_label:
...
Labels are “landmarks” - from which execution (control-flow) can be started, or - to which it can be diverted
Comparisons
cmp a1, a2
- Perform a (numeric) comparison between the values
a1
anda2
, and - Store the result in a special processor flag
Jumps
jmp LABEL # jump unconditionally (i.e. always)
je LABEL # jump if previous comparison result was EQUAL
jne LABEL # jump if previous comparison result was NOT-EQUAL
Use the result of the flag set by the most recent cmp
* To continue execution from the given LABEL
QUIZ
Which of the following is a valid x86 encoding of
if 10:
22
else
33
Strategy
To compile an expression of the form
if eCond:
eThenelse:
eElse
We will:
- Compile
eCond
- Compare the result (in
eax
) against0
- Jump if the result is zero to a special
"IfFalse"
label- At which we will evaluate
eElse
, - Ending with a special
"IfExit"
label.
- At which we will evaluate
- (Otherwise) continue to evaluate
eTrue
- And then jump (unconditionally) to the
"IfExit"
label.
- And then jump (unconditionally) to the
Example: If-Expressions to Asm
Lets see how our strategy works by example:
Example: if1
Example: if2
Example: if3
Oops, cannot reuse labels across if-expressions!
- Can’t use same label in two places (invalid assembly)
Oops, need distinct labels for each branch!
- Require distinct tags for each
if-else
expression
Types: Source
Lets modify the Source Expression to add if-else
expressions
data Expr a
= Number Int a
| Add1 (Expr a) a
| Sub1 (Expr a) a
| Let Id (Expr a) (Expr a) a
| Var Id a
| If (Expr a) (Expr a) (Expr a) a
Polymorphic tags of type a
for each sub-expression
- We can have different types of tags
- e.g. Source-Position information for error messages
Lets define a name for Tag
(just integers).
type Tag = Int
We will now use:
type BareE = Expr () -- AST after parsing
type TagE = Expr Tag -- AST with distinct tags
Types: Assembly
Now, lets extend the Assembly with labels, comparisons and jumps:
data Label
= BranchFalse Tag
| BranchExit Tag
data Instruction
= ...
| ICmp Arg Arg -- Compare two arguments
| ILabel Label -- Create a label
| IJmp Label -- Jump always
| IJe Label -- Jump if equal
| IJne Label -- Jump if not-equal
Transforms
We can’t expect programmer to put in tags (yuck.)
- Lets squeeze in a
tagging
transform into our pipeline
Transforms: Parse
Just as before, but now puts a dummy ()
into each position
> let parseStr s = fmap (const ()) (parse "" s)
λ
> let e = parseStr "if 1: 22 else: 33"
λ
> e
λIf (Number 1 ()) (Number 22 ()) (Number 33 ()) ()
> label e
λIf (Number 1 ((),0)) (Number 22 ((),1)) (Number 33 ((),2)) ((),3)
Transforms: Tag
The key work is done by doTag i e
- Recursively walk over the
BareE
namede
starting tagging at counteri
- Return a pair
(i', e')
of updated counteri'
and tagged expressione'
QUIZ
doTag :: Int -> BareE -> (Int, TagE)
Number n _) = (i + 1 , Number n i)
doTag i (Var x _) = (i + 1 , Var x i)
doTag i (Let x e1 e2 _) = (_2 , Let x e1' e2' i2)
doTag i (where
= doTag i e1
(i1, e1') = doTag _1 e2 (i2, e2')
What expressions shall we fill in for _1
and _2
?
{- A -} _1 = i
= i + 1
_2
{- B -} _1 = i
= i1 + 1
_2
{- C -} _1 = i
= i2 + 1
_2
{- D -} _1 = i1
= i2 + 1
_2
{- E -} _1 = i2
= i1 + 1 _2
(ProTip: Use mapAccumL
)
We can now tag the whole program by
Calling
doTag
with the initial counter (e.g.0
),Throwing away the final counter.
tag :: BareE -> TagE
= e' where (_, e') = doTag 0 e tag e
Transforms: Code Generation
Now that we have the tags we lets implement our compilation strategy
If eCond eTrue eFalse i)
compile env (= compile env eCond ++ -- compile `eCond`
ICmp (Reg EAX) (Const 0) -- compare result to 0
[ IJe (BranchFalse i) -- if-zero then jump to 'False'-block
,
]++ compile env eTrue ++ -- code for `True`-block
IJmp lExit ] -- jump to exit (skip `False`-block!)
[ ++
ILabel (BranchFalse i) -- start of `False`-block
: compile env eFalse ++ -- code for `False`-block
ILabel (BranchExit i) ] -- exit [
Recap: Branches
Tag
each sub-expression,- Use tag to generate control-flow labels implementing branch.
Lesson: Tagged program representation simplifies compilation…
- Next: another example of how intermediate representations help.
Binary Operations
You know the drill.
- Build intuition with examples,
- Model problem with types,
- Implement with type-transforming-functions,
- Validate with tests.
Compiling Binary Operations
Lets look at some expressions and figure out how they would get compiled.
- Recall: We want the result to be in
eax
after the instructions finish.
QUIZ
What is the assembly corresponding to 33 - 10
?
1 eax, ?2
?3 eax, ?4 ?
A.
?1 = sub
,?2 = 33
,?3 = mov
,?4 = 10
B.
?1 = mov
,?2 = 33
,?3 = sub
,?4 = 10
C.
?1 = sub
,?2 = 10
,?3 = mov
,?4 = 33
D.
?1 = mov
,?2 = 10
,?3 = sub
,?4 = 33
Example: Bin1
Lets start with some easy ones. The source:
Strategy: Given n1 + n2
- Move
n1
intoeax
, - Add
n2
toeax
.
Example: Bin2
What if the first operand is a variable?
Simple, just copy the variable off the stack into eax
Strategy: Given x + n
- Move
x
(from stack) intoeax
, - Add
n
toeax
.
Example: Bin3
Same thing works if the second operand is a variable.
Strategy: Given x + n
- Move
x
(from stack) intoeax
, - Add
n
toeax
.
QUIZ
What is the assembly corresponding to (10 + 20) * 30
?
mov eax, 10
1 eax, ?2
?3 eax, ?4 ?
A.
?1 = add
,?2 = 30
,?3 = mul
,?4 = 20
B.
?1 = mul
,?2 = 30
,?3 = add
,?4 = 20
C.
?1 = add
,?2 = 20
,?3 = mul
,?4 = 30
D.
?1 = mul
,?2 = 20
,?3 = add
,?4 = 30
Second Operand is Constant
In general, to compile e + n
we can do
compile e ++ -- result of e is in eax
[add eax, n]
Example: Bin4
But what if we have nested expressions
1 + 2) * (3 + 4) (
- Can compile
1 + 2
with result ineax
… - .. but then need to reuse
eax
for3 + 4
Need to save 1 + 2
somewhere!
Idea: How about use another register for 3 + 4
?
But then what about (1 + 2) * (3 + 4) * (5 + 6)
?
- In general, may need to save more sub-expressions than we have registers.
Question:
Why are 1 + 2
and x + y
so easy to compile but (1 + 2) * (3 + 4)
not?
Idea: Immediate Expressions
Why were 1 + 2
and x + y
so easy to compile but (1 + 2) * (3 + 4)
not?
As 1
and x
are immediate expressions: their values don’t require any computation!
Either a constant, or,
variable whose value is on the stack.
Idea: Administrative Normal Form (ANF)
An expression is in Administrative Normal Form (ANF)
ANF means all primitive operations have immediate arguments.
Primitive Operations: Those whose values we need for computation to proceed.
v1 + v2
v1 - v2
v1 * v2
QUIZ
ANF means all primitive operations have immediate arguments.
Is the following expression in ANF?
1 + 2) * (4 - 3) (
A. Yes, its ANF.
B. Nope, its not, because of +
C. Nope, its not, because of *
D. Nope, its not, because of -
E. Huh, WTF is ANF?
Conversion to ANF
So, the below is not in ANF as *
has non-immediate arguments
1 + 2) * (4 - 3) (
However, note the following variant is in ANF
let t1 = 1 + 2
= 4 - 3
, t2 in
* t2 t1
How can we compile the above code?
; TODO in class
Binary Operations: Strategy
We can convert any expression to ANF
- By adding “temporary” variables for sub-expressions
- Step 1: Compiling ANF into Assembly
- Step 2: Converting Expressions into ANF
Types: Source
Lets add binary primitive operators
data Prim2
= Plus | Minus | Times
and use them to extend the source language:
data Expr a
= ...
| Prim2 Prim2 (Expr a) (Expr a) a
So, for example, 2 + 3
would be parsed as:
Prim2 Plus (Number 2 ()) (Number 3 ()) ()
Types: Assembly
Need to add X86 instructions for primitive arithmetic:
data Instruction
= ...
| IAdd Arg Arg
| ISub Arg Arg
| IMul Arg Arg
Types: ANF
We can define a separate type for ANF (try it!)
… but …
super tedious as it requires duplicating a bunch of code.
Instead, lets write a function that describes immediate expressions
isImm :: Expr a -> Bool
Number _ _) = True
isImm (Var _ _) = True
isImm (= False isImm _
We can now think of immediate expressions as:
type ImmExpr = {e:Expr | isImm e == True}
The subset of Expr
such that isImm
returns True
QUIZ
Similarly, lets write a function that describes ANF expressions
ANF means all primitive operations have immediate arguments.
isAnf :: Expr a -> Bool
Number _ _) = True
isAnf (Var _ _) = True
isAnf (Prim2 _ e1 e2 _) = _1
isAnf (If e1 e2 e3 _) = _2
isAnf (Let x e1 e2 _) = _3 isAnf (
What should we fill in for _1
?
{- A -} isAnf e1
{- B -} isAnf e2
{- C -} isAnf e1 && isAnf e2
{- D -} isImm e1 && isImm e2
{- E -} isImm e2
QUIZ
Similarly, lets write a function that describes ANF expressions
ANF means all primitive operations have immediate arguments.
isAnf :: Expr a -> Bool
Number _ _) = True
isAnf (Var _ _) = True
isAnf (Prim1 _ e1 _) = isAnf e1
isAnf (Prim2 _ e1 e2 _) = isImm e1 && isImm e2
isAnf (If e1 e2 e3 _) = _2 && isANF e2 && isANF e3
isAnf (Let x e1 e2 _) = isANF e1 && isANF e2 isAnf (
What should we fill in for _2
?
{- A -} isAnf e1
{- B -} isImm e1
{- C -} True
{- D -} False
We can now think of ANF expressions as:
type AnfExpr = {e:Expr | isAnf e == True}
The subset of Expr
such that isAnf
returns True
Use the above function to test our ANF conversion.
Types & Strategy
Writing the type aliases:
type BareE = Expr ()
type AnfE = Expr () -- such that isAnf is True
type AnfTagE = Expr Tag -- such that isAnf is True
type ImmTagE = Expr Tag -- such that isImm is True
we get the overall pipeline:
Transforms: Compiling AnfTagE
to Asm
The compilation from ANF is easy, lets recall our examples and strategy:
Strategy: Given v1 + v2
(where v1
and v2
are immediate expressions)
- Move
v1
intoeax
, - Add
v2
toeax
.
compile :: Env -> TagE -> Asm
Prim2 o v1 v2)
compile env (= [ IMov (Reg EAX) (immArg env v1)
Reg EAX) (immArg env v2)
, (prim2 o) ( ]
where we have a helper to find the Asm
variant of a Prim2
operation
prim2 :: Prim2 -> Arg -> Arg -> Instruction
Plus = IAdd
prim2 Minus = ISub
prim2 Times = IMul prim2
and another to convert an immediate expression to an x86 argument:
immArg :: Env -> ImmTag -> Arg
Number n _) = Const n
immArg _ (Var x _) = RegOffset RBP i
immArg env (where
= fromMaybe err (lookup x env)
i = error (printf "Error: '%s' is unbound" x) err
QUIZ
Which of the below are in ANF ?
{- 1 -} 2 + 3 + 4
{- 2 -} let x = 12 in
+ 1
x
{- 3 -} let x = 12
= x + 6
, y in
+ y
x
{- 4 -} let x = 12
= 18
, y = x + y + 1
, t in
if t: 7 else: 9
A.
1, 2, 3, 4
B.
1, 2, 3
C.
2, 3, 4
D.
1, 2
E.
2, 3
Transforms: Compiling Bare
to Anf
Next lets focus on A-Normalization i.e. transforming expressions into ANF
A-Normalization
We can fill in the base cases easily
Number n) = Number n
anf (Var x) = Var x anf (
Interesting cases are the binary operations
Example: Anf-1
Left operand is not immediate
Key Idea: Helper Function
imm :: BareE -> ([(Id, AnfE)], ImmE)
imm e
returns ([(t1, a1),...,(tn, an)], v)
where
ti, ai
are new temporary variables bound to ANF expressionsv
is an immediate value (either a constant or variable)
Such that e
is equivalent to
let t1 = a1
...
, = an
, tn in
v
Lets look at some more examples.
Example: Anf-2
Left operand is not internally immediate
Example: Anf-3
Both operands are not immediate
ANF: General Strategy
- Invoke
imm
on both the operands - Concat the
let
bindings - Apply the binary operator to the immediate values
ANF Implementation: Binary Operations
Lets implement the above strategy
Prim2 o e1 e2) = lets (b1s ++ b2s)
anf (Prim2 o (Var v1) (Var v2))
(where
= imm e1
(b1s, v1) = imm e2
(b2s, v2)
lets :: [(Id, AnfE)] -> AnfE -> AnfE
= e
lets [] e' :bs) e' = Let x e (lets bs e') lets ((x,e)
Intuitively, lets
stitches together a bunch of definitions:
lets [(x1, e1), (x2, e2), (x3, e3)] e===> Let x1 e1 (Let x2 e2 (Let x3 e3 e))
ANF Implementation: Let-bindings
For Let
just make sure we recursively anf
the sub-expressions.
Let x e1 e2) = Let x e1' e2'
anf (where
= anf e1
e1' = anf e2 e2'
ANF Implementation: Branches
Same principle applies to If
- use
anf
to recursively transform the branches.
If e1 e2 e3) = If e1' e2' e3'
anf (where
= anf e1
e1' = anf e2
e2' = anf e3 e3'
ANF: Making Arguments Immediate via imm
The workhorse is the function
imm :: BareE -> ([(Id, AnfE)], ImmE)
which creates temporary variables to crunch an arbitrary Bare
into an immediate value.
No need to create an variables if the expression is already immediate:
Number n l) = ( [], Number n l )
imm (Id x l) = ( [], Id x l ) imm (
The tricky case is when the expression has a primitive operation:
Prim2 o e1 e2) = ( b1s ++ b2s ++ [(t, Prim2 o v1 v2)]
imm (Id t )
, = makeFreshVar ()
t = imm e1
(b1s, v1) = imm e2 (b2s, v2)
Oh, what shall we do when:
If e1 e2 e3) = ???
imm (Let x e1 e2) = ??? imm (
Lets look at an example for inspiration.
That is, simply
anf
the relevant expressions,- bind them to a fresh variable.
@(If _ _ _) = immExp e
imm e@(Let _ _ _) = immExp e
imm e
immExp :: Expr -> ([(Id, AnfE)], ImmE)
= ([(t, e')], t)
immExp e where
= anf e
e' = makeFreshVar () t
One last thing: Whats up with makeFreshVar
?
Wait a minute, what is this magic FRESH ?
How can we create distinct names out of thin air?
(Sorry, no “global variables” in Haskell…)
We will use a counter, but will pass its value around
Just like
doTag
anf :: Int -> BareE -> (Int, AnfE)
Number n l) = (i, Number n l)
anf i (
Id x l) = (i, Id x l)
anf i (
Let x e b l) = (i'', Let x e' b' l)
anf i (where
= anf i e
(i', e') = anf i' b
(i'', b')
Prim2 o e1 e2 l) = (i'', lets (b1s ++ b2s) (Prim2 o e1' e2' l))
anf i (where
= imm i e1
(i' , b1s, e1') = imm i' e2
(i'', b2s, e2')
If c e1 e2 l) = (i''', lets bs (If c' e1' e2' l))
anf i (where
= imm i c
(i' , bs, c') = anf i' e1
(i'' , e1') = anf i'' e2 (i''', e2')
and
imm :: Int -> AnfE -> (Int, [(Id, AnfE)], ImmE)
Number n l) = (i , [], Number n l)
imm i (
Var x l) = (i , [], Var x l)
imm i (
Prim2 o e1 e2 l) = (i''', bs, Var v l)
imm i (where
= imm i e1
(i' , b1s, v1) = imm i' e2
(i'' , b2s, v2) = fresh i''
(i''', v) = b1s ++ b2s ++ [(v, Prim2 o v1 v2 l)]
bs
@(If _ _ _ l) = immExp i e
imm i e
@(Let _ _ _ l) = immExp i e
imm i e
immExp :: Int -> BareE -> (Int, [(Id, AnfE)], ImmE)
= (i'', bs, Var v ())
immExp i e l where
= anf i e
(i' , e') = fresh i'
(i'', v) = [(v, e')] bs
where now, the fresh
function returns a new counter and a variable
fresh :: Int -> (Int, Id)
= (n+1, "t" ++ show n) fresh n
Note this is super clunky. There is a really slick way to write the above code without the clutter of the i
but thats too much of a digression, but feel free to look it up yourself
Recap and Summary
Just created Boa
with
- Branches (
if
-expressions) - Binary Operators (
+
,-
, etc.)
In the process of doing so, we will learned about
- Intermediate Forms
- Normalization
Specifically,


This page is build using a simple template file found at WEB-INF/page-templates/base-page.html
which
contains a custom action mycommand.HelloCommand
The source for the command is :
package mycommand; import java.io.IOException; import java.io.OutputStream; import org.protorabbit.model.impl.BaseCommand; public class HelloCommand extends BaseCommand { @Override public void doProcess(OutputStream out) throws IOException { String message = "hello "; if (params.length > 0) { message += params[0]; } out.write(message.getBytes()); } }
To use the tag simply call it from your template:
<% mycommand.Hello('Proto Rabbit') %>
That is pretty much it. Have fun.

How to download videos on Disney+ on Android
Source: Ara Wagoner / Android Central
Disney+ is here and there are thousands upon thousands of hours of Disney magic to watch, but no one wants to see the data overcharges you could rack up streaming it while you're away from Wi-Fi. Thankfully, you can download videos quite easily on Disney+, from movies to individual episodes to entire TV shows, but since Disney+ defaults to the lowest download quality, I highly recommend changing it to Medium or High before you start downloading videos.
How to change your Disney+ download quality
- Open the Disney+ app.
- Tap your Profile picture in the bottom right corner of the screen.
- Tap App Settings. Source: Ara Wagoner / Android Central
- If you don't want to wait until you're back on Wi-Fi to download your videos, you can tap Download Over Wi-Fi Only to toggle it off.
- Tap Download Quality.
- Tap the quality you prefer to use for downloads. Under each quality it tells you how many hours of content you could download at each rate before you completely fill your device's storage. Source: Ara Wagoner / Android Central
Now that you've got your quality squared away, let's get some of our favorites downloaded for when we get trapped in a dead zone.
How to download videos in Disney+
- Open the Disney+ app.
- Tap a movie you want to download.
- Tap the download icon next to the Play and Add to Watchlist icons.
- Tap the back arrow in the top left corner of the screen. Source: Ara Wagoner / Android Central
- Tap a TV show you want to download.
- To download a whole season, tap the download icon to the right of the Season number.
- To download an individual episode, tap the download icon to the right of the episode's title, next to the Info icon. Source: Ara Wagoner / Android Central
Repeat as desired with all of your favorite shows and movies. You currently can't download extras like behind-the-scenes and audio commentary versions, but every episode and movie is available for download.
How to manage downloads
When you want to browse your downloaded videos and clear some of them out, you can watch and manage them all from one place: the Downloads tab.
- Open the Disney+ app.
- Tap the Downloads tab (third icon from the left in the bottom row of icons).
- Tap a show you are downloading episodes from.
- To batch delete episodes, tap Edit. Source: Ara Wagoner / Android Central
- To select episodes to batch delete, tap the checkbox to the right of the episode.
- To select all episodes, tap the select all button in the top right corner (square icon surrounded by a dotted square).
- Tap the trash can icon to delete your selected episodes.
- Tap the phone icon (or progress icon if the episode is still downloading) icon to the right of an episode or movie.
- Tap Remove Download to delete the video from your device.
- If the video is currently downloading, tap Pause Download to hold off on downloading that particular video at the moment. If you're downloading a lot of videos, you'll have to hit pause on each and every video if you want to pause them all. Source: Ara Wagoner / Android Central
The option to batch delete can be very useful for clearing out episodes of a show you've already watched to make room for new content.

Disney+ serves up hundreds of movies and shows from Marvel, Lucasfilm, Pixar, National Geographic, Fox, and of course Disney's expansive vault. You can download every episode and movie for offline palyback, but be mindful of your download quality. Video tends to eat storage space.

Saghir Bashir (www.ilustat.com)
Sometimes after an event you need to issue certificates to the participants. How do you normally produce several certificates automatically? There are different ways to do it and here we share our approach after a recent community event1. We used R to automatically generate the certificates using R markdown and LaTeX language.
The key objective was to produce PDF certificates that could be emailed to attendees (see above for an example).
We started with a certificate template in R markdown format (with LateX) containing the following tags <<ATTENDEE_NAME>>
, <<EVENT_NAME>>
, <<EVENT_DATE>>
and <<EVENT_LOCATION>>
. These tags were replaced by attendee and event information from a data.frame
. The PDF certificates were produced using rmarkdown::render()
whilst looping over the attendee data.frame
.
A fixed working directory using set_here()
2.
Dataset with attendee and event (name, date and location) information.
A certificate template in R markdown format.
library(tidyverse)
library(rmarkdown)
library(stringr)
library(here)
set_here() # Need this later especially when rendering R markdown
Let assume that our dataset of attendees is as follow:
attendees <- read_csv(here("AttendeeList.csv")) %>%
mutate(filePDF = str_c("PDF/", row_number(), "_",
str_replace_all(Name, fixed(" "), "_"), ".pdf")) %>%
select(filePDF, Name, Event, Date, Location)
attendees
## # A tibble: 3 x 5
## filePDF Name Event Date Location

Next we developed a certificate template using R markdown, with tags (i.e. << ... >>
) for the attendee and event information. Our template is saved in a file called Certificate_Rmd_Template.txt
:

latex_engine: xelatex

\begin{center}
{\Huge\bf Certificate of Attendance} \\
\vfill
{\Huge\bf <<ATTENDEE_NAME>>} \\
\vfill
{\Huge\it <<EVENT_NAME>>}

The certificates were generated using a function that combines the previous steps. The comments in the function code below describe what is going on.
certificate <- function(template, attendeeName, event, eDate, eLocation, outPDF, knitDir){
cat("\n Starting:", outPDF, "\n")
# Create a temporary Rmd file with the attendee and event information.
templateCert <- read_file(template)
tmpRmd <- templateCert %>%
str_replace("<<ATTENDEE_NAME>>", attendeeName) %>%
str_replace("<<EVENT_NAME>>", event) %>%
str_replace("<<EVENT_DATE>>", eDate) %>%
str_replace("<<EVENT_LOCATION>>", eLocation)
# The knitdir has to be defined for the rmarkdown::render to work.
RmdFile <- tempfile(tmpdir = knitDir, fileext = ".Rmd")
write_file(tmpRmd, RmdFile)
# Creating the certificates using R markdown.
rmarkdown::render(RmdFile, output_file = here(outPDF), quiet = TRUE)
# Temporary .Rmd file can be deleted.
file.remove(RmdFile)
cat("\n Finished:", outPDF, "\n")
}
Now we can create all the certificates by looping over the attendee data.frame
.
for (i in seq_len(nrow(attendees))) {
with(attendees,
certificate(template = here("Certificate_Rmd_Tempate.txt"),
Name[i], Event[i], Date[i], Location[i], filePDF[i], here())
)
}

You can view the PDF certificates:
We have presented a way to create PDF certificates of attendance based on a user defined “template”. The template was populated with the attendee and event information from which PDF certificates were generated using R markdown. This approach can be used to produce other types of documents, for example, “mail merges” and setting different exercises or exams for students. Our code can be run directly from the R console or as a batch job thanks to the rmarkdown
and here
packages.

Suitcases double as infantcases in China
ABC News | Submitted by: Tim Howard
Let's see; toothbrush, clean underwear, change of socks, baby, check. OK, let's travel. "Some of the infants were two or three to a suitcase. The nylon suitcases were stacked on the luggage rack, the back row of seats and along the sides of the bus. The babies appeared to have been drugged to keep them from crying and being found... They had been on the bus for four or five hours before they were found."

ClearChannel sponsors pro-war rallies
Chicago Tribune | Submitted by: Mayhem303
"Clear Channel radio stations in Atlanta, Cleveland, San Antonio, Cincinnati and other cities have sponsored rallies attended by up to 20,000 people. The events have served as a loud rebuttal to the more numerous but generally smaller anti-war rallies... The sponsorship of large rallies by Clear Channel stations is unique among major media companies, which have confined their activities in the war debate to reporting and occasionally commenting on the news."

US wants Security Council to help pick up the pieces
Sydney Morning Herald | Submitted by: Crow
"As the clock to war ticked down, the United States was already mapping plans for rebuilding Iraq, and quietly asking for the United Nations Security Council's help... "It is inappropriate for the aggressors to now act as if they are also the saviours," said one diplomat. "We still have a bad taste in our mouths and cannot swallow this new plan from them just yet."

Internet rocket car costs father a foot
Courier-Mail | Submitted by: Hans Krule
Stupid headline, not so much a case of an "Internet" rocket car, as a "dumbass" rocket car: Jeff Barlow, manager of the nearby One Mile Pub, said Mr Cannon and his sons had "souped up" a balsawood toy car by using a pipe packed with sparkler dust to propel it, after finding instructions on the Internet... "I believe it did some sort of loop and came back and routed them, then just happened to explode when it was close to people."

Bombing County Monaghan
The Register | Submitted by: Vomit
Why, then, can these flag-waving Irish Americans not unfurl their banner with pride? Well, the reason is that the said standard carries an outline map of Monaghan, which bears an uncanny resemblance to an outline map of Iraq. Terrifying... "It came as quite a surprise to us that Monaghan and Iraq had basically the same outline shape. We had been receiving some jeers and comments as we assembled for the parade in New York and we couldn't understand why. Until someone pointed out the similarity."

Tornado magnets increasing
WOKR-TV 13 Rochester | Submitted by: Captain Prozac
Of the 55 people who died in tornadoes nationwide last year, 37 were in mobile homes... why are we not surprised? Scientific studies are under way to determine whether twisters are naturally drawn to plastic lawn flamingos and old, rusty cars on blocks. The article goes on that if you have a tornado choice between a trailer and an automobile, go with the automobile.

Weakest Link used to test why we discriminate
Seattle Times | Submitted by: I think I shit my pants
"Hispanics and older people face discrimination, but blacks and women do not: or at least not on one television game show, according to a University of Chicago economist who analyzed which contestants were voted off the "The Weakest Link" as a way of testing competing theories about why we discriminate." The Scientific Method is alive and well?

Prison for female circumcision holidays
Guadian | Submitted by: Ryan
Extraterritoriality rears its head in UK: "Parents who take their daughters abroad to be circumcised could be sentenced to 14 years in prison, if proposed legislation becomes law. The home secretary, David Blunkett, today backed a private members bill making it illegal for girls to be taken abroad for "female genital mutilation", and increasing penalties from five to 14 years."

FRIENDS beats out ENEMIES in Nielsen ratings
Washington Post | Submitted by: Rockpile
U.S. television networks, facing a bill of up to $20 million each per day to cover the Iraq war, found that "Friends" are more popular than enemies as a repeat episode of the top sitcom on Thursday night beat live war cover on ABC in the ratings... Goldman Sachs research estimated this week that the cost to the networks of continuous coverage of the war could be $5 million to $20 million per day, in a worst-case scenario, depending on the network."

I survived harpoon in face
Sun | Submitted by: Tim Howard
"Paramedics cut away most of the 2ft spear at the scene.
But the barbs pierced Matthew’s eye socket, cheek and jaw bones, and he had to wait fully conscious for 14 hours as surgeons worked out how to remove them without killing him... Medics refused to let mum Sally see Matthew at first, fearing the sight of the spear would make her collapse. Surgeons at John Radcliffe Hospital in Oxford spent seven hours removing the prongs. They later had to operate again to remove Matthew’s injured eye." Includes killer pix of Xray and face after surgery.

Girls and science don't mix
Newsday | Submitted by: Tim Howard
Hey, it's not rocket science, or is it? "Two 13-year-old girls suffered first and second-degree burns Thursday when the engine of an aerial rocket being exhibited at a science fair at St. Joseph School in Garden City ignited and went out of control, Nassau police said. Even though students were told not to bring the rocket engines to school, the engine of a 2-foot aerial rocket exploded, shooting orange and blue flames toward the auditorium ceiling, and burning the girls in their legs, Det. Raymond Kurz, of the Arson/Bomb Squad, said."

SA: Microsoft security equals false advertising
itWeb | Submitted by: Tim Howard
Butterfly's wings clipped: "The Advertising Standards Authority of SA (ASA) has ordered that a Microsoft ad implying that its software will bring about the extinction of the hacker is to be pulled for being "unsubstantiated and misleading". An objection was lodged by freelance journalist Richard Clarke, in his personal capacity, who complained that the advert was untrue. He claimed Microsoft software is littered with vulnerabilities." DUH! We have a word for people who run Microsoft as platforms for production servers: fools.

Advice for Liz Smart from convicted terrorist
CBS News | Submitted by: Tim Howard
"One of the few individuals who might know how Elizabeth Smart feels right now is Patty Hearst, who endured countless horrors at the hands of her kidnappers in 1974 before joining up with their political cause and robbing a San Francisco bank. Hearst's life with the abductors who called themselves the Symbionese Liberation Army finally ended with her arrest for the bank robbery, in which she had been photographed with a machine gun, causing many to wonder why she hadn't escaped her captors." Countless horrors? After she was busted the Hearst pumped her fist in 'Right On' fashion for salivating paparazzi.

Indonesia: grow vegetables to deter corruption

"Their official wages are barely enough to live on. It's better than extorting people or taking bribes." A hydroponics expert will demonstrate proper techniques. We aren't sure about Indonesia, but all the hydroponics experts we know are total potheads.

This should come as no surprise, but we've been using blocks this whole time. A block of code is simply a piece of code that is passed through a method via the use of curly braces {...} or do...end syntax. For example:
[1, 2, 3].each {|x| puts x*2}
[1, 2, 3].each do |x|
puts x*2
end
Very familiar right? So why do we need Procs and Lambdas? Let me try to explain.
As you can see, we have to retype blocks every time we want to reuse them, which can get tedious. Here's where Procs come in. We can store a block for later use in a Proc Object. Rewriting the above example as a Proc would look like the following:
double_num = Proc.new {|x| x*2}
If we called the Proc object:
[1, 2, 3].double_num.call(2)
=> 4
Now we don't have to rewrite the block every time we want to pass the method.
Lambdas are nearly identical to Procs but have a couple key differences. First of all, a lambda checks for the number of arguments, whereas a proc does not:
l = lambda {"I'm a lambda"}
l.call
=> "I'm a lambda"
l.call("arg")
=> ArgumentError: wrong number of arguments (1 for 0)
Secondly, the "return" keyword is treated differently by lambdas and procs. In a proc, a return statement halts the method, where lambdas allow them to continue:
def proc_math
Proc.new {return 1 + 1 }.call
return 2 + 2
end
def lambda_math
Lambda.new {return 1 + 1 }.call
return 2 + 2
end
proc_math # => 2
lambda_math # => 4
As you can see, the proc_math returns the value of the return statement inside the Proc, and the lambda_math skips the return statement and evaluates the value outside.
In summary, the main differences between Blocks, Procs, and Lambdas are:
