Performs Geographically Weighted Fractal Analysis (GWFA) to calculate the local fractal dimension of a set of points. GWFA mixes the Sandbox multifractal algorithm and the Geographically Weighted Regression. Unlike fractal box-counting algorithm, the sandbox algorithm avoids border effects because the boxes are adjusted on the set of points. The Geographically Weighted approach consists in applying a kernel that describes the way the neighbourhood of each estimated point is taken into account to estimate its fractal dimension. GWFA can be used to discriminate built patterns of a city, a region, or a whole country.

USD/CAD price analysis: Greenback trades sideways against Canadian dollar, near 1.3250 level
by Flavio Tosti- USD/CAD is correcting last week upmove in quiet Monday’s trading.
- The level to beat for buyers is the 1.3282 resistance.
USD/CAD daily chart
The loonie on the daily chart is consolidating last Friday’s surge. This Monday, the spot is trading quietly between the 100 and 200-day simple moving averages (DMAs).
USD/CAD four-hour chart
USD/CAD got a substantial boost at the end of last week and the market is currently correcting that move. Buyers want to capitalize on the momentum and break the 1.3282 resistance to drive prices towards the 1.3337 level. Further up lies the 1.3371 resistance, according to the Technical Confluences Indicator.
USD/CAD 30-minute chart
USD/CAD is having a sideways consolidation above the 100 and 200 SMAs. Bulls will try to defend the 1.3247 support. However, failure to do so can see the 1.3200 handle back into play for bears. Further down lies the 1.3158 support level.

'Affliction' (1998)
A movie review by Walter Frith
<EMAIL_ADDRESS>Member of the ‘Online Film Critics Society' http://ofcs.org/ofcs/
'Affliction' is not as obvious a film as it may seem. Besides showing the inherited traits that are often passed down from father to son, this film also strives to show one man weak enough to actually swallow that theory whole. His feeling of worthlessness, his dysfunctional life, his incompetence on the job, and his ability to eventually alienate everyone in his life he cares about but he manages to hang on to the one person most detrimental to himself before things turn tragic and the course of his life will be changed forever by the film's conclusion.
Nick Nolte as Wade Whitehouse, gives his finest performance to date as a small town police officer in upstate New Hampshire who looks the other way for his so-called friends, has an ex-wife who hates him, a young daughter who finds him weird, and a girlfriend (Sissy Spacek) who tries, unsuccessfully, to change him. He drinks and while indications of the film's description you may have read elsewhere may lead you to believe that alcoholism is the inspiration for the film's title, the real affliction is the monstrous behaviour burdened upon Nolte by his brooding, violent, irresponsible and alcoholic father Glen (James Coburn). Coburn's portrayal is, in many ways, more scary than most manufactured monsters shown in some of the most sinister horror and science fiction films. Uncaring, unloving and a human being with absolutely no redeemable qualities, Coburn is one of the sharpest supporting players seen in film in years and his character is so realistic that it will haunt many long after they leave the theatre.
The film has narration by Wade's brother Rolfe (Willem Dafoe). Dafoe also has a small part as Wade's younger brother who leads a normal life and despises the abyss his father and brother have fallen into. He is a successful school teacher and the remarks aimed at his family are less than endearing.
'Affliction' is based on the novel by Russell Banks, the author of 'The Sweet Hereafter' and the film is written for the screen and directed by Paul Schrader who has worked on such screenplays for the movies as 'Taxi Driver' and 'Raging Bull'. Schrader's screenplays and in this case his direction, looks abstract to the genuine concept of entertainment. I also had a similar criticism of 1998's 'A Simple Plan', which generated a similar feeling as this film does. Just because these films purport to tell a story about the true condition of the human soul and how it can be destroyed can make for fine film focus but they often have limited entertainment value attached to them, especially with such a downer ending, which they often contain.
To expand on the comments made about Nick Nolte and James Coburn, I must say that I never expected them to be as perfect on screen as father and son as they are in the finished product. Coburn has always been an under rated actor and has always managed to please in his employment as a performer. And what can you say about Nick Nolte? A man with only one Oscar nomination to his credit for 1991's 'The Prince of Tides', this film could easily win Nolte an Oscar but it wouldn't be genuine unless Coburn also wins. Although there is only twelve years between them in real life, they truly look like father and son on screen. Nolte should have received additional Oscar nominations in his career for work in 'North Dallas Forty', 'Under Fire' and 'Weeds'.
The last thing that I can say about this film is that Nolte's performance, while totally convincing and heartbreaking is also the stuff that fits the first line of this review in so much that his performance is not obvious. For the first hour or so, his character is rather sedated. But we come to later realize that Wade Whitehouse is a man who has in fact, bottled up his feelings for so long that when the film concludes, we find that sometimes it's better to let your feelings out rather than control them to the point where they build to the point of eruption which is inevitable among human beings.

This document outlines all the commands available for use in MOSS along with each form of each command and some information about the command.
The MOSS CPU is made up of several different components. Most of these are the result of influences from x86 and ARM based processors.
Like many CPU designs the MOSS CPU has a set of 16 general purposes registers. These registers are capable of storing both 32bit integers and 32bit float numbers. This allows for swapping between the different types of numbers relatively painlessly.
While a simple program can be exectued using only register values (and no use of the stack), you still need as every program lives somewhere in memory. As there is no concept of protected memory it's entirely possible for a program to deliberately or accidentally change it's own code.
The amount of memory available to the CPU is configurable, but defaults to 128kb.
What is a stack? A stack can be though of just like a physical stack of objects, like a stack of plates. You can only add items to the top of the stack and only take the top most item off the stack.
In the MOSS CPU there are two stack pointers, basically areas of memory that are set aside for keeping track of data on the stack.
The first stack is the data stack. This is available via the PUSH and POP commands and are useful for any time you might want a global stack, most likely when calling functions.
The second stack is the code stack, this one keeps track of the current program counter (where are you in the code) value. This is used when the CALL command jumps to a function, the current program counter is pushed onto the stack. This allows the RETURN command to go back to where the CALL command was.
main: PUSH 8 ; Push 8 onto the stack. PUSH 4 ; PUsh 4 onto the stack. CALL combine ; Call the combine function. POP r0 ; The combine function has one result, so we put that into register 0. INFO r0 ; Display the result, which will be 32. HALT ; End the program. combine: POP r10 ; Get the top most item which will be 4. POP r11 ; Get the next top most item, which is 8. MUL r10 r11 ; Combine the two values in an arbirary way. ADD r10 8 PUSH r10 ; Push the result of the function onto the stack so that ; the code that called this function can get the value. RETURN ; Return back to the part of the code that called this function.
[optional conditional] [command] [any number of arguments]
main: MOV r0 4 ; Is split into ['MOV', 'r0' '4'] MOV r1 6.7 ; Is split into ['MOV', 'r0', '6.7'] CMPF r1 10.0 ; Is split into ['CMPF', 'r1', '10.0'] > INCF r1 ; Is split into ['>', 'INCF', 'r1'] < DECF r1 ; Is split into ['<', 'DECF', 'r1']
| Form Code | Description | ||||||
|---|---|---|---|---|---|---|---|
|
R
Register
|
A register referes to one of the registers in the CPU.
They are always referenced with a lowercase R followed by a number,
eg r0 or r12 .
Each register can hold one 32bit value, either a 32bit integer or 32bit float.
For example:
ADD r0 r1 ; Add register 1 onto register 0. |
||||||
|
I
Interger
|
Integer values can only store whole numbers. They are officially called
immediate values however here I've simply called them integers.
The name immediate value comes from the fact that the value is known 'immediately'
at compile time and so will be part of the code and no further look ups are
required to get the value.
For example:
MOV r0 7 ; Set register 0 to the integer 7. ADD r0 6 ; Add the interger 6 to register 0. |
||||||
|
F
Float
|
Floating Immediate value, or simply a float value which is a value that
can hold decimal numbers.
For example:
MOV r0 8.3 ; Set register 0 to the float 8.3. SUBF r0 3.3 ; Subtract the float 3.3 from register 0. |
||||||
|
N
Any Number
|
Number. For commands where either an integer or float value is acceptable.
Such as the PUSH command which pushes a value onto the stack, it doesn't care if it's
an integer or a float, they're both 32bits of information.
For example:
PUSH 4 ; Put an integer onto the stack. PUSH 8.9 ; Put a float onto the stack. POP r0 ; Take the top most value and store it in register 0. POP r1 ; Take the next top most value and store it in register 1. |
||||||
|
S
String
|
String value. This is a bit of a special case because strings cannot be created at
run time just yet, however they can be compiled in and used for
debugging purposes.
They are a list of characters surrounded by " (double quote) characters.
The \\n sequence can be used to output a new line.
For example:
PRINT "-- Here are the results --\\n" PRINT "r0 = " PRINT r0 PRINT "\\n" |
||||||
|
M
Memory Location
|
Memory location value. If you want to store values somewhere more long lasting you
should store them into memory somewhere. A memory location is just a value to
somewhere in memory that is currently stored in a register.
For example:
MOV r0 5 ; Set the memory location to 5. MOV @r0 10 ; Set the memory at the location stored in register 0 ; (which is 5) to be 10. INC r0 ; Increment the memory pointer. MOV @r0 15 ; Set the memory at the location stored in register 0 ; (which is now 6) to be 15. MOV r1 @5 ; Set register 1 to the memory in position 5. MOV r2 @6 ; Set register 2 to the memory in position 6. INFO r1 ; Prints 10. INFO r2 ; Prints 15. |
||||||
|
O
Memory Offset
|
Memory location offset value. Just like the memory location that used a register
for the location, the offset value is just a hardcoded number.
For example:
MOV @0 756 ; Set the memory in position 0 to 756. MOV @1 123.345 ; Set the memory in position 1 to 123.345. MOV r5 @0 ; Set register 5 to the value in memory at position 0. MOV r6 @1 ; Set register 6 to the value in memory at position 1. INFO r5 ; Print 756 INFO r6 ; Print 123.345. |
||||||
|
L
CPU Flag
|
Within the CPU there is a special register called the flags register.
This one register can store up to 32 different true/false values that are can be
used by the CPU and program to communicate. It is possible to set these flags
manually using the MOV command. However some are only intended to be viewed
rather than set directly.
|
||||||
|
A
Special Register
|
Within the CPU are a few special registers that affect how it works.
For example:
MOV r0 PROGRAM_COUNTER MOV r1 STACK_POINTER MOV r2 CODE_STACK_POINTER INFO r0 ; Tells you what the program counter was at the start. INFO r1 ; Tells you what the stack pointer was at the start. INFO r2 ; Tells you what the code stack pointer was at the start. |
MOV r0 0 start_loop: CMP r0 10 >= JMP end_loop PRINT r0 PRINT "\\n" INC r0 JMP start_loop end_loop: PRINT "Loop complete\\n"
my_func1: POP r0 MUL r0 3 PUSH r0 RETURN main: PRINT "Start of program\\n" PUSH 5 CALL my_func1 POP r5 INFO r5
my_func1
and any of it's code is not executed on startup because the first thing that's called is the PRINT
command.
main: MOV r0 8 CMP r0 10 == PRINT "8 == 10" ; Will not print as 8 equals 10 is false. != PRINT "8 != 10" ; Will print as 8 does not equal 10 is true. > PRINT "8 > 10" ; Will not print as 8 is greater than 10 is false. >= PRINT "8 >= 10" ; Will not print as 8 is greater than or equal to 10 is false. < PRINT "8 < 10" ; Will print as 8 is less than 10 is true. <= PRINT "8 <= 10" ; Will print as 8 is less than or equal to 10 is true.
var age = 20; if (age > 30) { console.log("Older than 30") } else if (age > 15) { console.log("Older than 15") } else { console.log("Younger than or equal to 15"); }
main: MOV r0 20 ; We'll assume r0 to be the age variable. CMP r0 30 > JMP older_than_30 CMP r0 15 > JMP older_than 15 PRINT "Younger than or equal to 15\\n" JMP end older_than_30: PRINT "Older than 30\\n" JMP end older_than_15: PRINT "Older than 15\\n" JMP end end:

Applications that simply work
We want to deliver a full fledged playground for any hobbiest at any level to learn complex java skills and knowledge without the challenge of software hindering your ability to learn a new software development concept
We really want to deliver developers creating rest API's using the ClinkWorks-Platform, easy means to create their own applications with out of the box support for valuable development techniques and education about API design.
The idea is that it is possible to create a simple system with minimum viable product design with modular service based architecture at the for front of our api choices. Taking this approach with strict test driven development with a focus on a service based architecture.
We have decided that it was time to take our hobbiest nature to the next level. We want to provide tooling and know how to developers of any skill level seeking to build their own products
We are attempting to create a data broker called ClinkWorks-Platform that is as close to Java SE compliant as we can make it without adding any strict learning curves in any of the given supported technologies.
One of the big things I felt as a new developer in the enterprise world is just how many different xml configuration files you were required to learn at a very quick pace. Xml files for conifguring databases, xml files for identifying constructors. xml files for this that and the other.
Modern application development tooling is also so difficult to learn since you are never exposed to it in the achedemic world. So we decided to host a full fledged application stack including a CI server, multiple enviroment configurations for the build, and all that fun stuff.

KSI and Logan Paul clash at public workout as YouTube stars close in on rematch
The pair will meet in the ring for the second time this weekend in front of 20,000 fans in Los Angeles
by Martin Domin, https://www.facebook.com/mirrorfightingAs the sun set on Venice Beach, the question which lingered was whether this weekend will herald a new dawn in boxing.

There was certainly a bemused look on the faces of the eclectic bunch who had gathered along this stretch of California’s coast.
And what genuine stars of the sport - and world champions to boot - Billy Joe Saunders and Devin Haney thought is anyone’s guess.
But a good half hour after the latter left the ring, Logan Paul climbed through the ropes in front of a smattering of lingering fans.
Bizarrely he didn’t pull on his gloves, instead doing laps of the ring, skipping and shadow boxing as his trainer, former heavyweight world champion Shannon Briggs, told him which camera lens to look into next.
Eventually the waiting KSI lost his patience and climbed up on to the ring apron and beckoned over his rival.
And so ensued the classic fight-week exchange designed only to sell tickets and drive subscriptions and pay-per-view buys.
“KSI, my friend,” said Paul. “You have four days to bake the cake.

As Paul left the ring, KSI - real name Olajide William Olatunji - had a heated exchange with Briggs before entering the ring.
He at least gloved up and threw some punches, although you’d find better technique at any one of the dozen local keep fit gyms.
Whatever you make of it, in three days the biggest fight of the weekend will be between two social media stars with two white-collar bouts between them.
It’s boxing, but not as we know it.

ROAD SMASH
Woman rushed to hospital after being knocked down by car outside Bearsden primary school
by Justin BowieA WOMAN was rushed to hospital after being knocked down by a car outside a Bearsden Primary School.
Emergency services raced to the scene at around 4.10pm after the grim road smash on Duntocher Road in the town.
It happened near to St Nicholas' Primary school.
The road was locked down by cops as the pedestrian injured in the crash was taken to hospital.
Her condition is currently unknown.
And Duntocher Road remains closed around the scene of the incident.
A Police Scotland spokesperson said: "We were called at around 4.10pm to a crash on Duntocher Road involving a car and female pedestrian.
"The pedestrian was taken to hospital.
"Her condition is currently unknown."


KEALib provides an implementation of the GDAL data model. The format supports raster attribute tables, image pyramids, meta-data and in-built statistics while also handling very large files and compression throughout.
Based on the HDF5 standard, it also provides a base from which other formats can be derived and is a good choice for long term data archiving. An independent software library (libkea) provides complete access to the KEA image format and a GDAL driver allowing KEA images to be used from any GDAL supported software.
Development work on this project has been funded by Landcare Research.
Once you have installed Conda, run the following commands
on the command line to install kealib and GDAL:
conda config --add channels conda-forge
conda config --set channel_priority strict
conda create -n myenv gdal
conda activate myenv
Drivers for ArcMap and ERDAS Imagine are available from GitHub
Fedora and EPEL 8 (Centos etc) plugins for GDAL are available from Fedora COPR
KEALib requires: HDF5 with the C++ libraries and headers. GDAL is required to build the GDAL driver.
Download releases through Git at GitHub
Some documentation on compilation is available in the KEALib wiki.
Documentation on the GDAL data model and API is available from the GDAL website.
There is also a paper describing the features of the format.


Stakeholders’ support enables timely disposal of cases: DIG
Police holds coordination meet with other depts. to sort out issues
by Staff ReporterDeputy Inspector General of Police (Eluru Range) A.S. Khan on Saturday sought support from all government departments for timely disposal of cases.
Mr. Khan accompanied by Krishna in-charge District Judge E. Bheema Rao participated in a coordination meeting between the police and other government departments.
Mr. Khan said every attempt was being made to reach out to the public through various initiatives such as Spandana.
Presenting a picture of policing in Krishna district, Superintendent of Police M. Ravindranath Babu claimed that the average monthly death toll of 30 in road accidents had been brought down to 20 over the half year, with more vigil on the national highways round the clock.
“In Spandana, the Krishna district has registered 96% redressal rate against 1,721 petitions received since the programme was launched. We are now accessible to the public both online and offline,” said Mr. Ravindranath Babu.
District Revenue Officer A. Prasad expressed readiness to issue necessary certificates sought by the police to speed up investigation into the SC and ST atrocity cases and land dispute cases. Mr. Prasad also pledged to depute field-level staff to intensify raids on illegal sand transportation.
The Prisons Department officials said video-conference facilities would soon be launched in prisons for online trial of court cases.
The Public Prosecutors clarified doubts on filing chargesheets in various cases.
The officials of forest, fisheries, mines and geology, medical and health departments were present.


There we go. This is the first time we've written something equivalently with reduce
and map
, but the reduce
way resulted in processing the xs
a single time, whereas the map
way needed to iterate over xs
twice.
Let's add another wrinkle. Say we didn't just want those primes that are of the form n*n+1
for 2 <= n <= 100
, but we wanted to find their sum. It's a very easy change:

I honestly don’t think that here been any shocking revelations of or new discoveries from the core component of foundations. Coming from a Psychology background and having worked as a therapist for 6 years, I feel that I’ve done a lot of these types of activities before. If anything it served as a refresher for those ideas and skills which I have learned in the past.
My complete inability to concentrate during the headspace activities after my second coffee.
Probably the identity and values exploration, the reflection part was easy enough but conveying it in a way to share with others was more difficult.
There might be a lot of jobs out there but there are also a lot of fledging developers looking to get a piece of that pie. If an employer encounters two candidates with equivalent skills then the deciding factor is going to be how well the employer thinks that each candidate will fit within the company. Our people skills are the things which help us become better fits. Being able to play as part of a team, listen and function under pressure are all skills that help us to increase our chances of success.
I can see why it was done. I preferred the programming elements of the course, the core elements served as mini breaks for me. I think that if a student puts a lot into the core exercises and really absorbs the meaning behind them, then yeah, the core is great for that type of student. But if you go into them with a somewhat cynical or skeptical outlook then you’re probably not going to benefit as much.

The report identifies the lessons learned from the Foundation Learning provision
to help further education and skills providers develop study programmes for young people who need support to further their education or training.
On 1 August, the Foundation Learning provision will move into the new 16 to 19 Study Programmes. The study programmes are for all learners aged 16 to 19 and include all levels up to level 3, including A levels. The Foundation Learning provision is funded by the Education Funding Agency (EFA). Its purpose is to provide learners with individualised learning programmes to support their progression to further education, training or employment.
Latest figures show that 152,000 16 to 18 year olds were not in education, employment or training for the last quarter of 2013. From 1 September 2013, all young people aged up to 17 will be required by law to be in Further Education, training or employment. Many of these young people will have similar needs to those on Foundation Learning provision. Colleges and providers will need to be ready to provide support for this group of people.
The new traineeships launched by Matthew Hancock, the Minister for Skills in May will be part of the new Study Programmes and are likely to be highly suitable for this group of learners to help them progress to further vocational training, especially apprenticeships.
However, the survey report for 2011/12, found only 49% of learners on Foundation Learning provision progressed onto full-time education, training, apprenticeships or employment.
Matthew Coffey, Director of Learning and Skills for Ofsted said:
It is important for the Government and the sector to learn lessons from previous programmes highlighted in this report, which will aid the development of the 16 to 19 Study Programmes. Since the full implementation of Foundation Learning provision in August 2010, the number of learners who go onto full time education or training, an apprenticeship or employment has been too low.
To break this pattern, providers must make use of best practice in understanding why some providers are succeeding where others fall short.
The report highlights the positive characteristics of the programmes including:
-
comprehensive initial assessments to identify specific areas of need for individual learners
-
good support and guidance by staff and external agencies that were very effective in enabling young people who had been disengaged from learning to return to study
The report found that when developing the Study Programmes for this group of learners, providers need to make better use of work experience. The availability, use and quality of work experience were poor. Only 3 of the 41 providers visited in the sample offered work experience placements to all their learners. Work experience is a significant feature of 16 – 19 Study Programmes. Ofsted’s report highlights three providers that have achieved this very successfully in order to share good practice.
Study Programmes should also focus on improving impartial advice for learners in relation to progression routes as too many providers did not make adequate arrangements to support learners’ decision-making about career options.
Inspectors also found providers should use data effectively to track and analyse performance of young people’s success in finding suitable employment. A large proportion of providers had not systematically recorded learners’ destinations since the start of the Foundation Learning provision, when they no longer received payment for learners moving onto further education, employment or training.

Community Training Services Limited
This example shows how Community Training Services Limited (CTS) works effectively in partnership with Keir Sheffield LLP, Sheffield Homes and Sheffield City Council on the City Stewardship Programme. The programme targets young people who are the furthest removed from the job market and aims to provide skills, motivation and the work ethic they need to find employment. Of particular interest is the opportunity it provides for learners to experience real work in horticulture and construction.
Economic Solutions Limited (Skills Solutions)
This example shows how Skills Solutions (part of the Economic Solutions Group) has developed a wide range of high-quality work experience opportunities including tasters, work placements and work trials. They cover a variety of vocational options to reflect learners’ preferences and to improve their employability skills.
The Bassetlaw Training Agency
Work experience and the development of employability skills are often seen as weaker areas for learners on Foundation learning programmes. This example explains how Bassetlaw Training Agency (BTA) has taken robust action to ensure that all learners are encouraged to develop these skills from the very first day of their programme. The curriculum successfully prepares learners for progression into workplace learning by offering individual programmes and qualifications to support employability skills.

Blood Simple *** (out of four) R, 1984 Directed by Joel Coen. Written by Joel and Ethan Coen. Starring John Getz, Frances McDormand, Dan Hedaya, M. Emmet Walsh.
It might surprise some to know that Joel and Ethan Coen, who have brought such unabated lunacy to our movie screens as "Raising Arizona" and "The Hudsucker Proxy," made their feature film debut with "Blood Simple," a grim and often gruesome tale of revenge, murder, and literally fatal misconceptions in rural Texas. It bears some resemblance, story-wise, to the Coens' recent "Fargo," but even the darkly satirical humor and the enjoyably quirky characterizations that characterized that film are scarce here; "Blood Simple" is pretty much cold and brutal from beginning to end.
The premise of "Blood Simple" is really just a slight variation on the standard love-triangle/revenge scheme: sleazy bar owner Julian Marty (Dan Hedaya) hires a shifty private detective (M. Emmet Walsh) to kill his wife Abby (Frances McDormand) and her illicit lover Ray (John Getz). Things start to go haywire when Walsh decides instead to fake the murder with photographic trickery but, upon collecting the money, becomes uncertain as to whether or not Marty is capable of keeping his mouth shut about the scheme.
To reveal any more details of the story would be to give away too much, but what ensues is a series of bloody (and I do mean bloody) confrontations, each triggered by one or more characters misunderstanding what is actually happening. Every act of violence or deception in this film makes sense when seen through the perpetrator's eyes, but we, the audience, are made privy to the "big picture" and thus can recognize that each misdeed is somehow either unnecessary or directed at the wrong person. This aspect of the story, along with the intense atmosphere of repulsion and brutality - one gets the sense that if guns and, in one case, shovels, were not available, some of these characters would claw each other to death - are the most effective components of the film. The Coens might have done well to title the film "Fear and Loathing in Texas."
Some have labeled "Blood Simple as a modern-day noir, but, while I am not an expert on either genre, it seems more like a horror movie than anything else. The Coens seem much more interested in the plot twists and the atmosphere of confusion and paranoia than they do in the characters, and the final sequence is nothing more than a showdown between the one (relatively) innocent character and the only one of the murderers left alive. That said, "Blood Simple" is a very good horror movie; the fear and suspense here are genuine. The Coens also add plenty of quirky touches that nudge the weirdness meter upwards, such as when a character enters an empty room and accidentally steps on a gun, discharging it as it skitters across the floor, or when a murder attempt unfolds in a way such that Abby mistakes her attacker for another character who has in fact been killed earlier in the film.
That said, "Blood Simple" is not exactly flawless. For one thing, the motivations for the killings are still a little thin at times; I can understand that the characters had tracks to cover (or at least thought they did), but I found it a little hard to accept that all of them would so quickly resort to murder. And although they at least didnŐt have anyone get hacked to death with a knife, the Coens also aren't quite immune to horror cliches; they indulge in a prolonged dead-guy-seems-to-have-come-back-to-life-but-then-we-find-out-it's-only-a-dream scene that had me rolling my eyes. The film also ends so quickly after the final confrontation that I found myself wondering if they had simply run out of film.
"Blood Simple" is not quite the masterpiece of neo-noir that many seem to think it is, but it's a decent movie and it showcases the Coens' ability to handle suspense and violence in a visceral but non-exploitative manner. I would firmly recommend it to all "Coen-heads" as well as anyone looking for something original in a thriller.

r2 has an embedded webserver and ships some basic user interfaces written in html/js.
$ r2 -c=H
‘seek’ command is abbreviated as ‘s’
ex:-
[0x000000]> s + 10
[0x000000]> s +0x25
[0x000000]> s + [0x100+ptr_table]
[0x000000]> s++ :- seek forward
[0x000000]> s– :- seek backward
‘print’ alias as ‘p’ <- it takes number of submodes - the 2nd letter secifying a desired mode.
ex:-
[0x000000]> px :- to print in hexadecimal
[0x000000]> pd :- for disassembling
to be allowed to write files (-w) option to r2 when opening a file.(‘x’ subcommand for hexpairs),(‘a’ subcommand for even assembly opcodes)
ex :-
[0x000000]> w hello world :- string
[0x000000]> wx 90 90 90 90 :- hexpairs
[0x000000]> wa jmp 0x808140 :- assemble
[0x000000]> wf inline.bin :- write contents of file
append ‘?’ to a command will show its help message
ex:-
[0x000000]> a? :- will show all commands starting with a
[0x000000]> VV :- To enter block Visual mode
[0x000000]> q :- To exit block Visual mode
in visual mode we can use HJKL keys to navigate(left,down,up,right ,respectively)
cursor mode :- toggled by ‘c’ key in toggle mode we can arrange the alignment of the code
$ ‘TAB’ :- to toggle between differnt parts of the code(blue border shows on which block you are)
To enter Visual mode(hex representation) :- $ V To exit block Visual mode :- $ q in visual mode we can use HJKL keys to navigate(left,down,up,right ,respectively) To overwrite the bytes:- $ i ‘TAB’:- To switch between the hex(middle) and string(right) columns
to scroll different visual mode representation:- $ p or P
MOST IMPORTANT VISUAL MODE curses-like panels interfaces:- $ V!
'F7' or 's' :- step into current instruction
'F8' or 'S' :- step over current instruction
'F2' :- to set breakpoints
This mode contains many options on the top.You can use it like an application and navigate to different part of code
cursor mode :- toggled by ‘c’ key to select a byte range in cursor mode :- SHIFT + H SHIFT + J SHIFT + K SHIFT + L
Important command line options ——————————- -A :- run ‘aaa’ command to analyze all referenced code -B [addr] :- set base address for PIE binaries -c ‘cmd..’ :- execute radare command -C :- file is host:port(alias for -c=https://%s/cmd/) -d :- debug the executable ‘file’ for running ‘pid’ -D [backend] :- enable debug mode -H ([var]) :- display variable -K [OS/kern] :- set asm.os (linux,macos,w32,netbsd,…) -m [addr] :- map file at given address(loadaddr) -M :- do not demangle symbol names -p [prj] :- use project ,list if no arg,load if no file -P [file] :- apply repatch file and quit -s [addr] :- initial seek -w :- open file in write mode
Common usage patterns ——————————– Open a file in write mode without parsing the file format headers $ r2 -nw file
Quickly get into an r2 shell without opening any file $ r2 -
Set the configuration variable $ r2 -e scr.color=0 blah.bin
Use an existing project file $ r2 -p test
Command Format ———————————– general format [.][times][cmd][~grep][@[@iter]addr!size][|>pipe] ;
to repeatedly execute a command,prefix the command with a number px #run px 3px #run px 3 times
To execute a command in shell context :- prefix ‘!’ To use the cmd callback from the I/O plugin :- prrfix with ‘=!’
ex:- $ ds :- call the debugger’s ‘step’ command $ px 200 @ esp :- show 200 hex bytes at esp $ pc > file.c :- dump buffer as a C byte array to file.c $ wx 90 @@ sym.* :- write a nop on every symbol $ pd 2000 | grep eax :- grep opcodes that use the ‘eax’ register $ px 20 ; pd 3 ; px 40 :- multiple commands in a single line
pipe (‘|’) is available in r2 shell can be used to filter the output with commands like wc,grep,less
there is also built-in grep(~)
$ ~? :- for help ‘~’ character enables internal grep-like function used to filter output of any command
ex:- pd 20~call :- disassemble 20 instructions and grep output for ‘call’ pd 20~call:0 :- get first row pd 20~call:1 :- get second row pd 20~call[0] :- get first column pd 20~call[1] :- get second column pd 20~call:0[0] :- grep the fist column of the first row matching ‘call’
’@’ character is used to specify a temporary offset at which command to its left will be executed
ex:- $ pd @ 0x100000fce :- to disasemble 5 instructions at address 0x10000fce
$ !~… :-to see the history
EXPRESSIONS ——————————– to evaluate mathematical expressions pretend them with command ‘?’
[0xb7f9d810]> ?vi 0x8048000 134512640 [0xv7f9d810]> ?vi 0x8048000+34 134512674 [0xb7f9d810]> ?vi 0x8048000+0x34 134512692 [0xb7f9d810]> ? 1+2+3-4*3 hex 0xfffffffffffffffa octal<PHONE_NUMBER>7777777777772 unit<PHONE_NUMBER>4.0G segment fffff000:0ffa int64 -6 string “\xfa\xff\xff\xff\xff\xff\xff\xff” binary 0b1111111111111111111111111111111111111111111111111111111111111010 fvalue: -6.0 float: nanf double: nan trits 0t11112220022122120101211020120210210211201
supporte arithmetic:- ‘+’,’-‘,’*’,’/’,’%’ ‘>’ :- shift right ‘<’ :- shift left
To use of logical OR , quote the whole comman to avoid executing | pipe: ex:- $ “? 1 | 2”
$ $$ :- here(the current virtual seek) $ $1 :- opcode length $ $s :- file size $ $j :- jump address(e.g. jmp 0x10) $ $f :- jump fail address (e.g. jz 0x10 => next instruction) $ $m :- opcode memory reference(e.g. mov eax,[0x10] => 0x10) $ $b :- block size
ex:- [0x4A13B8C0]> pd 1 @ +$l 0x4A13B8C2 call 0x4a13c000
Basic Debugger Session ------------------------------------------------ To debug a program ,start with '-d' option $ pidof <binaryname> :- to know the process id of binary 32220 $r2 -d 32220 :- to attach to that process
$ r2 -d
$ r2 -a arm -b 16 -d gdb://<IP_ADDRESS>:9090
To continue program until a specific address is reached ‘dcu’ (debug continue until) takes the address of the placee to stop at $ dcu main
Common commands used with debugger:- $ ds 3 :- step 3 times $ db 0x8048920 :- setup a breakpoint $ db -0x8048920 :- remove a breakpoint $ dc :- continue process execution $ dcs :- continue until syscall $ dd :- manipulate file descriptors $ dm :- show process maps $ dmp A S rwx :- change permissions of page at A and size S $ dr eax=33 :- set register value, eax = 33
To enter visual debugger mode use ‘Vpp’: [0xb7f0c8c0]> Vpp
Pressing ‘p’ will allow you to cycle through the rest of visual mode views ‘F7’ or ‘s’ :- step into current instruction ‘F8’ or ‘S’ :- step over current instruction ‘c’ :- to toggle the cursor mode ‘F2’ :- to set breakpoints
To see value of variable and its location
$ .afvd
In visual mode we can enter regular radare commands by prepending them with ‘:’ . ex:- <Press ‘:’> x @ esi
To get help on visual mode
Most strings are zero terminated.When we recover the control over the process,we get the arguments passed to syscall,pointed by %ebx.
[0x000000]> dcs open :- to continue the execution of a program until it executes the ‘open’ syscall
[0x000000]> dr eax 0xffffffda esi 0xffffffff eip 0x4a14fc24 ebx 0x4a151c91 edi 0x4a151be1 oeax 0x00000005 ecx 0x00000000 esp 0xbfbedb1c eflags 0x200246 edx 0x00000000 ebp 0xbfbedbb0 cPaZstIdor0 (PZI)

Polygon Set Concept
The polygon_set concept tag is
polygon_set_concept
The semantic of a polygon_set
is zero or more geometry regions. A Polygon Set Concept may be
defined with floating point coordinates, but a snap rounding distance
of one integer unit will still be applied, furthermore, geometry
outside the domain where one integer unit is sufficient to provide
robustness may lead to undefined behavior in algorithms. It is
recommended to use integer coordinates for robust operations. In
the case that data represented contains only Manhattan geometry a
runtime check will default to the Manhattan algorithm. The
results of which are identical to what the general algorithm would do,
but obtained more efficiently. In the case that the data
represented contains only Manhattan and 45-degree geometry a runtime
check will default to the faster 45-degree algorithm. The results
of which may differ slight from what the general algorithm would do
because non-integer intersections will be handled differently.
Users are recommended to use std::vector and std::list of user
defined polygons or library provided
polygon_set_data<coordinate_type> objects. Lists and
vectors of models of polygon_concept or polygon_with_holes_concept are
automatically models of polygon_set_concept.
Example code custom_polygon_set.cpp
demonstrates mapping a user defined class to the library
polygon_set_concept
An object that is a model of
polygon_set_concept can be viewed as a model of
polygon_90_set_concept or
polygon_45_set_concept if it is determined at runtime to conform
to the restrictions of those concepts. This concept casting is
accomplished through the view_as<>()
function.
view_as<polygon_90_set_concept>(polygon_set_object)
view_as<polygon_45_set_concept>(polygon_set_object)
The return value of view_as<>()
can be passed into any interface that expects an object of the
conceptual type specified in its template parameter. Polygon sets
cannot be viewed as single polygons or rectangles since it generally
cannot be known whether a polygon set contains only a single polygon
without converting to polygons.
Operators
The return type of some operators is the polygon_set_view operator template
type. This type is itself a model of the polygon 90 set concept,
but furthermore can be used as an argument to the polygon_set_data constructor and assignment
operator. The operator template exists to eliminate temp copies
of intermediate results when Boolean operators are chained together.
Operators are declared inside the namespace boost::polygon::operators.

Polygon Set Data Object
The polygon set data type encapsulates the internal data
format that serves as the input to the sweep-line algorithm that
implements polygon-clipping Boolean operations. It also
internally keeps track of whether that data has been sorted or scanned
and maintains the invariant that when its flags indicate that the data
is sorted or scanned the data has not been changed to violate that
assumption. Using the Polygon Set Data type directly can be more
efficient than using lists and vectors of polygons in the functions
above because of the invariants it can enforce which provide the
opportunity to maintain the data is sorted form rather than going all
the way out to polygons then resorting those vertices for a subsequent
operation.
The declaration of Polygon Set Data is the following:
template <typename T>
class polygon_set_data;
The class is parameterized on the coordinate data type.
Algorithms that benefit from knowledge of the invariants enforced by
the class are implemented as member functions to provide them access to
information about those invariants.
Example code polygon_set_usage.cpp
demonstrates using the library provided polygon set data types and

template
<typename output_container>
void get(output_container& output) const |
Expects a standard container of polygons objects.
Will scan and eliminate overlaps. Converts polygon set geometry
to objects of the polygon type and appends them to the container.
Polygons will be output with counterclockwise winding, hole polygons
will be output with clockwise winding. The last vertex of an
output polygon is the duplicate of the first, and the number of points
is equal to the number of edges plus 1. If required by the output
data type, polygons will have holes fractured out to the outer boundary
along the positive y direction and off grid intersections on the outer
boundary introduced by this fracture will be truncated downward.

intersections. |
template

bool operator==(const polygon_set_data& p) const |
Once scanned the data representation of geometry within
a polygon set is in a mathematically canonical form. Comparison
between two sets is therefore a linear time operation once they are in
the scanned state. Will scan and eliminate overlaps in both polygon
sets. Expected n log n runtime, worst case quadratic runtime wrt.

objects in the iterator range. |
template
<typename rectangle_type>
bool extents(rectangle_type& extents_rectangle) const |
Given an object that models rectangle, scans and
eliminates overlaps in the polygon set because subtractive regions may
alter its extents then computes the bounding box and assigns it to
extents_rectangle. Expected n log n runtime, worst case quadratic

preserved by default, segmented circular arcs are inserted if
corner_fill_arc is true. num_circle_segments specifies number of
segments to introduce on a full circle when filling acute angle corners
with circular arcs. Specifying zero for num_circle_segments
results in only a single segment being inserted at acute corners.
