The Problem
A common issue is that you have a project, that has one or more submodules or other private repository dependencies.
This means that you have to grant access to all repositories in order to make the build successful.
If your git hosting service supports it, the best, most secure way is to register the same SSH key for every repository you have to access during the build, as “Deployment keys”. Due to technical reasons (true for most git hosting services), you should not use multiple SSH keys, instead use the same SSH key for every repository!
If your git hosting service does not support the use of a single SSH key for multiple repositories (for example GitHub does not support this!), you’ll have to register the SSH key for a user account.
In this case (e.g. GitHub), there is an easy workaround for the issue. Simply by adding a “bot” / “machine” user with the SSH key to the repositories you can solve the problem. Add the SSH key you would like to use to the user and add the user to the projects. You don’t have to add the “bot” user with read and write permission, it is enough to assign read permissions. After that you can use the SSH key to clone to the repository or any submodule. It’s that simple.
On GitHub this is the recommended way to solve this problem, they refer to these kind of users as “machine” users - reference: https://developer.github.com/guides/managing-deploy-keys/#machine-users.
Of course it’s not required to use a special “bot” / “machine” user, you can add the SSH key to your own account on the git hosting service, but the best practice is to use a machine user for this use case, and grant read only access for this machine user, for those repositories you want to access during the build.
On GitLab and Bitbucket it’s possible to register a single SSH key as Deploy key to multiple repositories, without the need to create a “bot” / “machine” user.
!!! note “Use SSH URLs everywhere”
Most services support SSH key based authentication only for SSH URLs
(ex: git@github.com:bitrise-io/bitrise.git
), and not for HTTPS URLs
(ex: https://github.com/bitrise-io/bitrise.git
)!
This means, that every private repository you want to use have to be addressed with the SSH url.
If you have direct private git repo references in your Podfile
you’ll have to
use the SSH url there as well! Same applies for submodules and every other private
git repository url you want to use with the SSH key you register on Bitrise.io!
How to do this when you add a new app
There are three options to grant Bitrise access to your repository:
- Auto-add SSH keypair: Don’t use this option if you use submodules. This option will add the SSH key only to the main repository, the one you selected in the first section of the Add New App page.
- Generate SSH keypair: will generate a key for you on the Bitrise website and you will have to copy it manually to the given user. This is the recommended option if you want to use submodules / have to access multiple repositories during your build.
- Use your own SSH keypair: can be used if you also have the private key of the given user. You just have to paste the private key and Bitrise will be able to access the repositories. If you’d want to go with this option, it’s important that the SSH key have to be an RSA key, without a passphrase! You can find an example of how you can generate a key like that here.
When you already registered your App on Bitrise.io
When you’ve already registered an App, the steps to handle the SSH keys are the same
as when adding a new app, the only difference is
that you’ll have to do it on the app’s Settings
tab.
You can find the public SSH key of the app in the Settings
of the given
app on Bitrise. Simply scroll down to the “SSH settings” section
and click “Show SSH Public Key”.
Copy the key to the given user and you are ready to build! Or you can also update the given app’s SSH key by clicking the “Change SSH Keypair” button and choosing one of the three options, just like on the “Add new App” page.
Service specific notes / guides
Github
Don’t add the key to the repository as a Deploy Key! Add it to a GiHub User’s account instead, who has access to the repositories. The recommended way is to use a “machine” user, but of course you’re free to add it to any user account which has at least read only access to all of the repositories used during the build.


Module: WillPaginate::ViewHelpers::ActionView
- Includes:
- Base
- Defined in:
- lib/will_paginate/view_helpers/action_view.rb
Overview
ActionView helpers
This module serves for availability in ActionView templates. It also adds a new view helper: paginated_section.
Using the helper without arguments
If the helper is called without passing in the collection object, it will try to read from the instance variable inferred by the controller name. For example, calling will_paginate while the current controller is PostsController will result in trying to read from the @posts variable. Example:
<%= will_paginate :id => true %>
… will result in @post collection getting paginated:

 ...

Instance Method Summary (collapse)
-
- (Object) page_entries_info(collection = nil, options = {})

- (Object) paginated_section(*args, &block)
Wrapper for rendering pagination links at both top and bottom of a block of content.

Arguments are passed to a will_paginate call, so the same options apply. Don’t use the :id option; otherwise you’ll finish with two blocks of pagination links sharing the same ID (which is invalid HTML).

No guarantees for Murray at Davis Cup: Smith
by ReutersLONDON: Andy Murray is a welcome addition to Britain’s Davis Cup team but there is no guarantee the former world number one will play in the singles, team captain Leon Smith has said.
Murray, who underwent hip surgery in January, won the European Open in Antwerp last month but the three-times Grand Slam champion is the lowest-ranked singles player in the British team at 126 behind Dan Evans (42) and Kyle Edmund (69).
“Any time you can bring Andy into the team is going to make your team better,” Smith told reporters.
“He’s still working his way back to the level he wants to get to, so people have to keep the expectations of the right level of where he’s at just now.
“What he did in Antwerp was much talked about and a brilliant step forwards but you do have to remember this is early days in him coming back.
“We’ve got really good options. With Andy, with Evo (Evans), with Kyle, guys playing a very similar level – and with Jamie (Murray) and Neal (Skupski) we’ve got strong doubles options.”
The revamped Davis Cup format has group stage ties with two singles matches and one doubles match, with Britain drawn alongside Kazakhstan and the Netherlands.
Murray, 32, eased his way back into professional tennis by playing doubles, partnering with older brother Jamie in Washington earlier this year. Jamie said they would have to “wait and see” if they would pair up again in Madrid.
“It depends on how Andy’s feeling physically, what’s the best setup for the team on that day,” he added.
“But Neal and I have practised all week and we’re ready to play if called upon and I hope we’ll do a good job for the team.”

Nutmeg |
(plant material) |
One day I read that nutmeg was usable as a drug, and I got really interested and started to read all the experiences I could find. I didnít think it would be powerful at all, after what Iíve heard from my friends. Me and two of my friends bought 48 grams of nutmeg nuts. We ate this and it didnít give any effect (4 nuts each). We bought whole nuts from the convenience store, but I think these nuts miss the Ďmagicí ingredient.
My friends thought that nutmeg was total bullshit, but I didnít think so. Thursday I saw a guy who was selling fresh nutmegs. I bought 75 gram (13 nuts) for about $2,5. The different thing about these nuts was that when I tried to cut them with a knife, I could see some kind of black liquid appearing, something which hadnít happened the other times. I cut the nuts in small pieces and put them in my mouth and started to chew: 6 nuts equalling to about 35 g. Well, here is the stuff you probably want to read:
(I was having a test in German the following day. Take the test high, and get high scores (Redman) :p )
00:45 - 6 Nuts ingested
01:00 - Nothing except nutmeg burps. Went to bed.
06:30 - My dad tries to wake me up. I try to walk to the bathroom, but it feels like if my body weighs 300 pounds. When I got to the bathroom I was really nausea and I tried to puke. My heart raced like it have never done before. I was so dizzy that I felt absolutely NO GRAVITY. I told my parents that I wasnít feeling any well, and got back to my bad. (This was extremely difficult, I crawled back into the bed.)
Around 13:00 - My mom wakes me up and want to give me something to eat. I donít remember much of this, but I remember that I tried to eat while I was in bed. Suddenly I see white figures flying around in the room and my vision was flicking. Seconds later I was sleeping.
I woke up on Saturday at 06:45. I had been sleeping from Thursday night till Saturday morning. And when I woke up I was still dizzy and my vision was totally fucked. I wouldnít see straight and the image was very blurry the entire day.
Summary:
This was a WAY to high dose for me. If the house would have caught fire, I would have had NO CHANCE to get out. I was glued to my bed. Nutmeg forced me to stay in bed for over 30 hours straight. I was really calm the entire Ďtripí, so I got out of if quite easy. But if I wasnít that calm the trip would have been hell. I am going to try it again, but this time with half of what I had now. This was the most powerful thing I have ever done. USE AT EXTREME CAUTION!! You donít want to end up in your bed the entire weekend. Or at the hospital!
And I donít get it when people say that nutmeg resembles marijuana effects? On that Saturday when I woke, I was still dizzy from the nutmeg and I drank 9 beers (0,33l) and smoked little less than 1g in one joint. After the joint I could barely stand and think straight, but the nutmeg was so MUCH, MUCH stronger. I think this drug is for people who have tried a lot of similar drugs, not by teenagers who want to find a legal way of getting high (as myself).

Football: New York City splits with ex-Guardiola assistant Torrent
NEW YORK: New York City FC, which had the second-best record in Major League Soccer this year, has parted ways with coach Domenec Torrent, a former assistant to Pep Guardiola at Manchester City.
The team announced the amicable split with the 57-year-old Spaniard and his staff on Friday (Nov 8), a little more than two weeks after NYCFC, which topped the Eastern Conference with 64 points, was ousted by Toronto in the MLS playoffs.
Torrent replaced Patrick Vieira in June 2018 as coach of NYCFC.
"This is the right time for myself and my family to look for other opportunities as I develop my career as a head coach," Torrent said.
"I would like to thank NYCFC for giving me this opportunity. I've learned a lot during my time at the club."
NYCFC Vice Chairman Marty Edelman said the timing also worked for the team.
"In discussions with Dome since our season finished, we've decided that this is the right moment for both parties to focus on new opportunities," Edelman said.


More Virginia Counties Declare ‘Second Amendment Sanctuary’ Status
Giles County and Dinwiddle both adopted “Second Amendment Sanctuary” resolutions on November 21, 2019
by BreitbartMore Virginia counties declared “Second Amendment Sanctuary” status this week in an effort to get ahead of the gun control promises from Gov. Ralph Northam (D) and newly-elected Democrats.
On November 19, 2019, Breitbart News reported that Appomattox County Board of Commissioners passed a “Second Amendment Sanctuary” resolution, with the goal of opposing any efforts that would “unconstitutionally restrict gun rights.”
WHSV 3 reports that Giles County and Dinwiddle both adopted “Second Amendment Sanctuary” resolutions on November 21, 2019.
Dinwiddle Supervisor William Chavis said, “We have rights to bear arms. Point blank. And our county, we have a lot of hunters, lots of sportsmen that like to sport shoot.”
On November 8, 2019, Breitbart News reported that Gov. Northam responded to Democrat election victories by readying a war on guns.

`eve::shl`
(insert ../../../crumbs.html here)
Synopsis
====================================================================================================
**Required header:**
Function object representing the arithmetic left shift operation.
Member functions
====================================================================================================
Performs the [element-wise](../../../glossary.html#regular_) arithmetic left shift of the first parameter by the second one.
Parameters
----------------------------------------------------------------------------------------------------
`x`
: [value](../../concepts.html#value).
`n`
: [integral value](../../concepts.html#value).
Return value
----------------------------------------------------------------------------------------------------
Computes the [element-wise](../../../glossary.html#element-wise) arithmetic left shift of the first parameter by the second one.
the call `shl(x, n)` is equivalent to `x << n` if `x` is an [simd value](../../concepts.html#value).
The types must share the same cardinal or be scalar and if $N$ is the size in bits of the element type of `T`,
all [elements](../../../glossary.html#element) of n must belong to the
interval: `[0, N[` or the result is undefined.
!!! WARNING
Although the infix notation with `<<` is supported, the `<<` operator on
standard scalar types is the original one and so can not be overloaded on standard floating parameters
due to **C++** limitations.

# another dotfile repo? yes
Disclaimer: these dotfiles are constantly changing, because I can never make up my mind on how things should work
This repo contains dotfile configurations. It also contains a deployment script to install Vim, zsh, and tmux, if you do not have them already. The included software and there configuration files are meant to be a lightweight toolkit usable on any UNIX-based machine, hopefully.
Don’t be afraid! Fork this repository!
To install and deploy, copy and paste the following commands into your terminal:
cd ~
git clone https://github.com/cam-carter/dotfiles
cd dotfiles
./deploy
Requires Vim version 8 and for macOS users, Homebrew
Everything should work with Neovim (which I will be transitioning to in the coming months), if you switch over all the config files
You don’t have to worry about updating these configuration files every time the master branch is changed. The following few lines of code, found in ~/dotfiles/zsh/lib/zshrc-manager.sh
, updates the main git repository and the included submodules whenever a new terminal is launched:
echo "Updating configuration..."
(cd $HOME/dotfiles && git pull && git submodule update --init --recursive)
source $HOME/dotfiles/zsh/zshrc.sh
Your grandpa’s text editor! Vim has been in active development since 1979 with the release of vi in 2BSD. It is open-source and highly configurable… what’s not to love?
The configuration files included in this repo provide some improved key-bindingsand also a bundle of plugins useful for editing with Vim. Vim is a very difficult program to learn and get used to, but once you are able to conquer the steep learning curve, the power you command is incomparable (except for maybe Emacs).
All Vim plugins in this package are managed by pathogen.vim.
To add new plugins to Vim you can either place them inside ~/.vim/bundle
or you can add them as a submodule under ~/dotfiles/vim/.vim/bundle
. For example, to install fugitive.vim (which is included with these dotfiles), run the following commands:
cd ~/dotfiles/vim/.vim/bundle
git submodule add https://github.com/tpope/vim-fugitive
The plugins are currently sourced using a symbolic link between ~/.vim/bundle
and ~/dotfiles/vim/.vim/bundle
.
Zsh (Z shell) is a Unix shell that can be used as a powerful command interpreter for shell scripting. The first version of Zsh was written by Paul Falstad in 1990.
Attached with these dotfiles include an assortment of Zsh plugins, managed with Oh My Zsh!, and custom aliases and functions.
| Function | Description |
|---|---|
cd |
Works like the default cd function, but it also lists the contents of the directory that you change into. |
ctrl+k |
This function changes to the parent directory cd .. |
ctrl+h |
This function changes to the user’s home directory cd ~ |
ctrl+l |
This function lists the contents of the working directory ls |
ctrl+space |
This function clears the current terminal window clear |
ctrl+g |
While inside a git repository, this function will add all changes to be committed, commit the changes, using the buffer as the commit message, and then push the changes upstream git add -A; git commit -m "$BUFFER" && git push |
enter |
If the buffer is empty, the enter key lists the contents of the current directory ls . If it buffer is empty and the working direcotry is a git repository, then it will show the git status of the current repository git status |
tmux is a terminal multiplexer, allowing a user to access multiple terminal sessions inside a single terminal window or a remote terminal session. It is extremely useful for handling multiple running terminal sessions.

// Piet Mondrian
"Art is not made for anybody and is, at the same time, for everybody." - Piet Mondrian
I started with Mondrian not because he is my favorite artist (he is not), or that his work is very recognizeable (it is), but because I thought it would be a fun (yes) and easy start (lol nope) to this project.
Mondrian was a Dutch painter who changed his name in 1906 from Pieter Cornelis Mondriaan as sort of a personal rebranding when he left the Netherlands for Paris. A man with as bad luck as the rest of us schmucks, he went back to the Netherlands to visit and ended up stuck there because of World War I (thanks Obama). He was able to go back to Paris in 1918, which seems to be when he changed his style from Post-Impressionist to the more abstract and grid-based work he is known for today.
His work from this time is categorized as part of the De Stijl movement. Also known as "neoplasticism," the style (literally the direct translation of "De Stijl") originated in Amsterdam shortly before he went back to Paris.
His evolution, from the traditional representation of objects in his older paintings to the very abstract use of just lines and rectangles to represent everything, paralleled his ideas that art is a spiritual representation of nature and that abstraction provides a common language for anyone to enjoy and understand art. And enjoy and understand people did and continue to do, as well as commodify, copy, and monetize.
 Fun fact to make this all about me: I almost died of pneumonia in New York.
* * *
I am quite fond of grids and tables and also primary colors, and Mondrian's very recognizable post-WWI work always catches my eye from afar in exhibits, so I decided to program his style of art generatively – that is, every time you run the code, you get a different "painting" thanks to the use of randomly generated variables. Hot off the heels of speaking about html tables at jQuery Conference Chicago, I decided to build this with tables.
The specific piece I used as my muse was Composition #10:
The fact that this painting is part of a private collection is astounding. Imagine just owning one of your own. Where would you even hang it? I haven't even finished hanging up all of my art, which are mostly band posters. Anyway, here is my skewed crayon version of Composition #10:
I use pen/crayon and paper to plan out and write algorithms before I type it out; it's just easier for me to think that way. Once I drew out the composition, I was able to figure out some aspects to the tables and tables within it, as well as the random cells of color. Here is my "hard-coded" HTML and CSS version of Composition #10:
See the Pen Mondrian's Composition #10 (ish) by Jenn (@jennschiffer) on CodePen.
There were a few aspects of this painting that I decided to take into consideration with JavaScripting Mondrian as I was manually building it in HTML:
- there are nested tables, but not for every cell #notallcells
- some cells have background colors [red, blue, yellow]
- some rows have different heights
- some cells have different widths
- the occurrence of the above characteristics are rare, and become even more rare as you go deeper into the nests
If things are nested, that is usually my cue to use recursion. In this case, it would be a weighted recursion, where the chance of continuing decreases dramatically each time. Composition #10 nests, at most, three levels. Also, the percentage of top-level cells having nesting is already pretty low, so the weight should start out as such.
I figure that I'd start with a 20% chance of a cell having a table inside it, and then depreciate that rate with each recursive call. I also want to be able to set the min and max number of rows and columns in each recursive call, since each nest level typically has fewer and fewer columns and rows.
Here is the initial code, which just generates the frame table and generatively paints our nested grid. Hover over the painting and click "RERUN" on the lower-right of the codepen to generate a new piece.
See the Pen JavaScripting Mondrian Pt. 1 by Jenn (@jennschiffer) on CodePen.
And, yeah, I use jQuery. Sorry not sorry, h8rs – Mondrian isn't the *only* cool kid who can use abstraction.
I thought the table generation would be the hard part, but actually it turns out the random styling of the cells got pretty tricky. Each cell is likely to have a non-white background. Also I randomly resized each row of the base/frame table.
See the Pen JavaScripting Mondrian Pt. 2 by Jenn (@jennschiffer) on CodePen.
At this point, I was having a hard time figuring out the borders for the nested tables. In his paintings, sometimes there are no borders, sometimes they are thicker than the rest of the painting. It took me a nap to realize that I should remove the border from cells that have a nested table. I love naps.
See the Pen JavaScripting Mondrian Pt. 3 by Jenn (@jennschiffer) on CodePen.
So, yeah, it still needs some more tweaking to get it *just right* but there you go – a generative Mondrian composition generator, written in JavaScript. You can check out a non-codepen demo showing a bunch of paintings all at once here.
It's also worth noting that other programmers have taken note of Mondrian's work. Last week I was at a bar telling my pal Steve Klabnik about this project, and he brought to my attention there are actual programming languages inspired by and/or named after Mondrian. See the "Related and worth checking out" links below.
 Watching my own progress in programming art that Mondrian did on his own with tangible media has definitely increased my awareness of the parallels between art created "in real life" and art created from inside a machine. Mondrian kind of had a computer all along, he just didn't have to deal with Firefox Aurora crashing because there were too many IRCCloud tabs open. I'd take a million browser crashes over getting pneumonia again, though.

load_image
(imagepath, dirname='', place_holder=False, recursive=False, ncase_cmp=True, convert_callback=None, verbose=False, relpath=None, check_existing=False, force_reload=False)¶ Return an image from the file path with options to search multiple paths and return a placeholder if its not found.
Parameters: - filepath (string) – The image filename If a path precedes it, this will be searched as well.
- dirname (string) – is the directory where the image may be located - any file at the end will be ignored.
- place_holder (bool) – if True a new place holder image will be created. this is useful so later you can relink the image to its original data.
- recursive (bool) – If True, directories will be recursively searched. Be careful with this if you have files in your root directory because it may take a long time.
- ncase_cmp (bool) – on non windows systems, find the correct case for the file.
- convert_callback (function) – a function that takes an existing path and returns a new one. Use this when loading image formats blender may not support, the CONVERT_CALLBACK can take the path for a GIF (for example), convert it to a PNG and return the PNG’s path. For formats blender can read, simply return the path that is given.
- relpath (None or string) – If not None, make the file relative to this path.
- check_existing (bool) – If true, returns already loaded image datablock if possible (based on file path).
- force_reload (bool) – If true, force reloading of image (only useful when check_existing is also enabled).
Returns: an image or None

Retrospective: Deliverance (1972) Review By: Ryan Davis
Sure there are many films that are called classics. But once I saw this, I knew where a number of newer films got some of their most impressive scenes. Unfortunately, the newer movies seem to execute them better than Deliverance.
Not to say Deliverance isn't a superb film, it is.  For the time this scene must have seemed very shocking, but now it just seems antiquated.
The story involves four men who decide to go on a weekend long canoe trip, in southern Georgia. They meet some strange inbreed locals, who along the way cause some trouble with the group. In what appears to be a life or death situation one of the locals is killed and the group must dispose of the body. Now scared, they begin their journey to the end of the river so they can get home. However, don't expect it to be a leisurely trip.
The performances of the four men (Jon Voight, Burt Reynolds, Ned Beatty, and Ronny Cox) are very impressive. Burt shows the same acting talent here, that he displays in the more recent "Boogie Nights". Ned is also standout as the poor overweight salesmen, who is sodomized by a hillbilly man.
John Boorman's direction is rather impressive. Although when compared to today's, it may seem rather conservative. Vilmos Zsigmond's beautiful cinematography does stand the true test of time, and is just as brilliant now as it was then.
Its hard to believe this movie was shot for a mere two million dollars, something that could never be done today. And even if this movie has not aged as well as some, it certainly is a must see because of its originality and maybe Ned squealing like a pig.

1 Then Elihu also said this:
2 "Job, do you really think that you have done nothing wrong?
You say, 'God knows that I am innocent,'
3 and you also say, 'What good have I received for not sinning?
What benefit have I received that I would not have had, even if I had sinned?'
4 Well, I will answer you,
and I will answer your three friends, too.
5 Job, look up at the sky;
look at the clouds that are high above you
and realize that God is far above everything, entirely out of your reach.
6 If you have sinned, that cannot harm God at all.
Even if you do wrong things many, many times, that certainly does not hurt him.
7 In the same way, if you are righteous, does that help God?
No, nothing you do can help him.
8 It is other people who can suffer because of the wicked things that you do;
In the same way, you might help others if you do good things for them.
9 People cry out because of the many things that others do to make them suffer;
they call for help because of the things that powerful people do to them.
10 But no one calls out to God
and says, 'Why does God, my creator, not help me?
He should enable me to sing joyful songs, instead of very sad songs, during the night.
11 He should be able to teach us more than he teaches the wild animals;
he should enable us to become wiser than all the birds are!'
12 People cry out for help,
but God does not answer them
because those who cry out are proud and evil people.
13 It is useless for them to cry out
because God, the Almighty One, does not pay any attention to what they say.
14 So when you complain that you cannot see God,
and you tell him that you are waiting for him to decide whether or not you have done wrong,
he will not listen to you, either!
15 Furthermore, you say that because he does not pay attention when people commit sins,
he does not become angry and punish them.
16 My friends, you see that Job has said things that are completely useless,
that he says many things without knowing what in the world he is talking about."


I love waking up in the morning and not knowing what's going to happen, or who I'm going to meet, where I'm going to wind up.

Purpose
I have a nice AVR ISP mkII and I'm living a happy relation ship with it, a nice menage a trois with Atmel Studio 6. But recently (2014/01/13) I bought a lucky bag at one of my favorites shop Akizukidenshi in Akihabara. Inside there was a handful of old discontinued ATmel chips like AT90S4414 or Attiny26L that can not be programmed with Atmel Studio 6.
Ok so solution is to use avrdude and the avg-gcc solution. So far so good. But to use the AVR ISP mkII I need to install alternate drivers, which I did try.
And there started problems: both drivers can't work at the same time (of course) means that I can use my programmer with Atmel Studio 6 or with avrdude, not both (unless some driver switching magic). So let's dig in that pile of various Arduinos I have and make something useful.
(5~6 years later) Jan 2020: ok I finally did it v(^_^)v It works, yet not perfect. In the meanwhile my environment changed from Windows to Linux and from AVR Studio to Eclipse, but yes, there we are!
Documentations
Bill of Materials
* Arduino 1.0 (I think), it even has the Italian flag sticker!
* An old board I got from Sparkfun discarded boards like 10y ago, apparently was made to be used with a GPS thingy?
* Wire, leds, resistors
Commands
READ ME: it works, but sometimes refuses commands, need to try a few time. One thing that came out of my testing is that forcing the baudrate (-b 19200) seems important, so do that future me.
Read low fuse: avrdude -c avrisp -p m328p -P/dev/ttyUSB0 -b 19200 -U lfuse:r:-:i -v
Program: avrdude -v -patmega328p -c avrisp -P/dev/ttyUSB0 -b19200 -Uflash:w:/path/to/program.hex:i
Code
In the arduino samples, the "ArduinoISP".
Following changes:
* defined the USE_OLD_STYLE_WIRING
because I started wiring like that before reading that we could use the SPI module itself and not bitbang it...
* as stated in the tutorial I edited the heartbeat()
to set a 40ms delay (not sure why, must mess up the timing of something else elsewere)

All files inside the proj folder must reside at your web servers root directory where the radiology system will reside. All links are relative and no folders or files need to be moved once they are put in their proper location.
There is a make file that can be used to setup your database with the proper tables and with a initial admin user set to Username: admin, password: Admin. This make file is located in the scripts folder and should be run from there. The make file can be altered to use a different username and password for sql plus login.
There is a make file inside the main system folder. This can be used to run the scripts and to ensure the web files have the right permissions however this file will not work properly if any of the folders are moved or renamed so be aware of this.

Building a Quant Finance Monte Carlo Engine in Haskell - Part 1
My background is in quant finance, mostly writing C++, Python, and (shudder) Matlab. Over the last few months I've been learning Haskell, so as an excuse to learn some more Haskell, I decided to try to solve a fundamental quantitative finance problem in Haskell. Quant finance tends to love tangled OOP, so I figured a functional programming style might be a new twist on the problem.
I was trying to think of a good problem to start with, and I came up with the idea of a simple (but powerful) Monte Carlo engine for Haskell. With that in mind, I started to think about architecture. I'm going to write this up in a few posts, but my rough plan is:
The target audience for this blog post is folks who know a bit of Haskell and are curious how it might apply to this particular problem.
If you know even a little bit about quant finance, you can skip this. For the rest of you, a few quick pointers:
A contingent claim is just a payout of cash that is dependent on something happening. The simplest contingent claim is a binary option. A binary option pays a fixed amount of cash immediately if some underlying (usually a stock) is above or below a certain amount. For instance, a binary call on XYZ stock with a fixed payout of $10 and a "strike price" of $50 will pay $10 if XYZ is above $50 at the option's expiration.
A Monte Carlo engine uses an underlying model to evolve values. Models specify a way of creating a growth rate and an idea of how the value will move (in some cases including a distribution). For instance, the most basic model (Black-Scholes), assumes that its values grow at a fixed interest rate and that they will follow a lognormal distribution. Models get very byzantine in some cases.
The first thing any Monte Carlo engine needs is a way to specify your payoffs. The great Simon Peyton-Jones himself has worked on this very problem. His solution is, of course, quite good, but it's actually too general for our purposes. There are many types of contracts that can be expressed in his system that cannot be easily priced in a Monte Carlo framework.
With that in mind, let's think about what a contingent claim really is, specifically from the standpoint of what a Monte Carlo engine needs to know about it.
The third of these is pretty easy to represent. For this one, we'll just create a list of times when the model needs to stop and check an observable. Easy enough.
Now for 1 and 2, let's make this a little simpler. What if every time we stop the model, we simply put a structure containing all of the observables into a Map, keyed off of a Time? Then we can finish specifying our contingent claim with a function with this type:
Map Time Observables -> CashFlow
Where a CashFlow is just:
data CashFlow = CashFlow { cfTime :: Time , cfAmount :: Double }
For now let's just imagine Observables is just a list of Doubles. In practice we're doing something better than that (see the bottom of this post for some details), but let's keep it simple for now.
After some iterations on the design, I came up with the following types to represent contingent claims.
data CCProcessor = CCProcessor {
monitorTime :: Time
, payoutFunc :: [Map Time Observables -> CashFlow]
}
newtype ContingentClaim = ContingentClaim { unCC :: [CCProcessor] }
If you can think about this from the standpoint of the Monte Carlo engine, the engine can tick through each element of the list. At each element it will evolve the simulation through until the given Time and put the Observables into a running Map. Once this is done it will run any payoutFunc that is available (or maybe multiple ones) and determine the cash flows that need to be processed.
One nifty thing about this is that it's easy to put together a bunch of different contingent claims simply by interleaving them based on the Time field.
-- | Combines two contingent claims into one.
combine :: ContingentClaim -> ContingentClaim -> ContingentClaim
combine (ContingentClaim x) (ContingentClaim y) = ContingentClaim $ combine' x y
where
combine' (cc1:ccs1) (cc2:ccs2)
| monitorTime cc1 == monitorTime cc2 = let
CCProcessor t mf = cc1
CCProcessor _ mf' = cc2 in
CCProcessor t (mf++mf') : combine' ccs1 ccs2
| monitorTime cc1 > monitorTime cc2 = cc2 : combine' (cc1:ccs1) ccs2
| otherwise = cc1 : combine' ccs1 (cc2:ccs2)
combine' cs1 cs2 = cs1 ++ cs2
But wait a sec, this is neat:
instance Monoid ContingentClaim where
mempty = ContingentClaim []
mappend = combine
So now I can very easily compose a bunch of different options together. That seems handy.
Now let's think about what a few simple options would look like in this framework. A binary call option with a payout of 50 with a strike of 100 on the 0th observable, paying out at time 1, would look like this:
binCall = ContingentClaim [1.0, [\m -> if m ! 1.0 !! 0 > 100 then 50 else 0]]
Okay, that's a bit ugly. Now imagine if I want a payout that averages the observable's price over ten different times? Trust me, I've tried, it isn't pretty.
So what we need is a way to build up a ContingentClaim in a nice composable way. Now the answer to every question in Haskell is "Make a monad!", and this is no different. So what I did was combined two monads, the Reader and Writer monad. The Reader monad (which is really just the function monad) allows me to build up my payout function in a pretty nice and composable way. Meanwhile the Writer monad keeps track of the times I'm checking the observable.
type CCBuilder w r a = WriterT w (Reader r) a
We'll also need something to pull our completed ContingentClaim out of the monad. The details of the implementation are beyond the scope of this (and tedious anyway), so just make note of the type:
specify :: CCBuilder ContingentClaim (Map Time Observables) CashFlow
-> ContingentClaim
Now let's make a function that checks an observable's value at a certain time. We'll call it monitor, and it'll check the 0th observable.
monitor :: Time -> CCBuilder ContingentClaim (Map Observables Double) Double
monitor t = do
tell $ ContingentClaim [CCProcessor t []] --adds to the list of Times
m <- ask --grabs the Map of values
return $ (m !
The details of the Reader and Writer monad are beyond the scope of this post, but suffice it to say that this adds to the running total of times to check the observable (tell), and while getting the value out of the map to use in the Reader monad.
Now we have all we need to build composable contingent claims. A few examples:
binCall strike t payout = specify $ do
x <- monitor t
let amt = if x > strike then payout else 0
return (CashFlow t amt)
vanillaCall strike t = specify $ do
x <- monitor t
let amt = max (x - strike) 0
return (CashFlow t amt)
--Calculates the average price on a series of times.
averagePrice priceTimes t = specify $
do x <- mapM monitor priceTimes
let val = sum x / fromIntegral (length x)
return $ CashFlow t val
--We can even do insane things
bizarre = specify $ do
x <- monitor 0.5
y <- monitor 1.0
z <- monitor 2.0
let t = if sin x > 0 then 7.0 else 2.0 --why would we do this???
return $ CashFlow t (cos (y + z))
--let's put a binary option together with a vanilla option!
portfolio = binCall 100 1 50 <> vanillaCall 100 1
Additionally the library contains some helpful functions like multiplier, which scales up a ContingentClaim payout by a constant factor. And of course I can make a function short = multiplier (-1)
. So a call spread could look like this:
callSpread lowStrike highStrike t = vanillaCall lowStrike t <> short (vanillaCall highStrike t)
Neat!
I mentioned earlier that the Observables type is a bit more sophisticated than I was letting on. The issue is that right now I can do this:
unsafeMonitor t = do
m <- ask
return (m ! t !! 3)
But what if 3 is out of bounds? With that in mind, I created types that represent fixed length vectors. For instance:
--I'm leaving out the UNPACK pragma and strictness annotations,
--but you get the idea.
data Observables1 = Observables1 Double
data Observables2 = Observables2 Double Double
-- ...
class Obs1 a where
obs1 :: a -> Double
class Obs2 a where
obs2 :: a -> Double
instance Obs1 Observables1 where
obs1 (Observables1 x) = x
instance Obs1 Observables2 where
obs1 (Observables2 x _) = x
instance Obs2 Observables2 where
obs2 (Observables2 _ x) = x
-- ...
Enough of that, you get the idea. Now a quick rewrite of the unsafeMonitor function:
monitor t = do
tell $ ContingentClaim [CCProcessor t []]
m <- ask
return (obs4 $ m ! t)
One last change:
data CCProcessor a = CCProcessor {
monitorTime :: Time
, payoutFunc :: [M.Map Time a -> CashFlow]
}
newtype ContingentClaim a = ContingentClaim { unCC :: [CCProcessor a] }
--we'll need RankNTypes
--contingent claims with one observable.
type ContingentClaim1 = forall a . Obs1 a => ContingentClaim a
--contingent claims with two observables.
type ContingentClaim2 = forall a . Obs2 a => ContingentClaim a
-- ...
And the type checker will now ensure that you're not accessing something that isn't being modeled. More on this when we get into the model implementation details.
You almost certainly haven't had as much fun reading this as I had writing the library. Haskell completely changes the way you solve problems, and while the abstractions are unfamiliar at first, they're remarkably powerful. It's still very much pre-pre-alpha but under heavy development.
In the mean time, check out the package on GitHub or Hackage.
Next time we'll cover a little bit about how we put together the engine itself and implemented models.


After learning the new IT skills from Dev Academy I will go back to my company and improve my company’s IT system and websites. I found that learning IT does not only teach me how to code but also how to think. The structure, logic, ways to make things work have already impressed me with the idea how a good system works. I could utilize this newly gained skills to re-shape and improve my whole company’s running system. As to my long term goal it stays the same. I would like to understand how this IT world works and be able to communicate with these people who shapes our future and become one of these people.
Sames as I mentioned before on the foundation learning plan my strengths are self-motivation, perseverance, proactive thinking and eager to learn pragmatic knowledge. My limitations are knowledge breadth, family duties, company duties. Time is a very scarce resource. I have to prioritize my life duties, family first, company second and then myself development. I just hope that during my learning time at bootcamp my family and my company all go well and I can fully focus on learning the new skills.
My biggest non-technical challenge at bootcamp might be arriving at bootcamp on time everyday. As I mentioned before I have my kids’ duty come first and plus the Auckland traffic is of no help. Certainly, I will try my best to arrive before the scheduled time.
It’s still the same that I’d like to become more patient and open-minded with other people’s ideas. Listening skill is what I need to develop.
I believe EDA already has a very good supportive environment and friendly facilitators. I expect when I have technical or non-technical issues the bootcamp facilitators can guide me through the process and reach the best solutions.
I expect that I learn everything that is taught at the Bootcamp. I understand this could be stressful and intensive. My determination will lead me through this process. If I encounter anything that I don’t understand for the first time ,I will, as long as time allows, study it again the second time, third time until I get it. I will seek for help from the internet, my peer learners and facilitators if necessary. I understand how important a teamwork is and it’s always in my mind that I should always treat others with respect and fairness.
My long term goal of learning IT is to understand how this IT world works and be able to communicate with these people who shapes our future and become one of these people.
My strengths of learning lies in being a self-motivated person with proactive thinking and eager to learn pragmatic knowledge. That’s why I took a break from my full time job and attended DEV Academy to prepare for my future. My limitation is that my knowledge breadth is limited as I’m only interested in learning the knowledge that I believe is useful.
In regards to human skills I’d to like to become more patient and open-minded with other people’s ideas. Listening skill is what I need to develop.
Since I’m committed to this learning programme I will try my best to overcome any obstacle that I may encounter. I will search internet for help or seek for help from my facilitators and other learners if necessary. If things are building up and starting to get to me I will take a short break, do some physical exercise or go for a walk and keep telling myself that where there’s a will there’s a way.
The facilitation team is supposed to help me out when I have problems with my learning. My experience so far suggests that they are doing very good job guiding me through and helping me out with my questions.
The two major commitments that I have besides learning are my kids and my company. I have pre-arranged all the matters before I attended EDA. I do spend some time with my kids and take care some of my company stuff daily. So far I manage it well. However, if anything happens that requires me to be there and caused some block-out times I will try my best to make it up.

NRL 2020: Kiwi Alex Glenn re-signs for two more years at Brisbane Broncos
Brisbane Broncos have re-signed veteran Kiwis back-rower and potential captain Alex Glenn for another two NRL seasons.
The 31-year-old looms as a replacement for under-fire Broncos leader Darius Boyd next season, after finally ending speculation and officially inking a deal until the end of 2021.
The veteran of 259 NRL games reportedly knocked back interest from Penrith to remain at Red Hill.

Glenn looks forward to stepping up in the absence of retired Matt Gillett, and providing guidance to a young Broncos outfit featuring David Fifita, Payne Haas and Kotoni Staggs.
"I've enjoyed being a leader for these boys," said Glenn. "We've had 12 debutants in 2019 and they have all deserved their jersey this year.
"But the thing that kept me going hard every single week was competing with these boys - they'll never beat me on my efforts."
Broncos coach Anthony Seibold said Glenn's experience would be vital, as they begin life after 200-game veteran forward Gillett next year.
"His consistency sets a great example for our whole squad and his leadership is important to the players at our club working to fulfil their potential," he said.
"He always works hard and always gives his all - we want everyone at this club to follow the example that he sets."
Brisbane will hope there are more player announcements to come.
Boom forward Fifita - off contract in 2020 - is still in talks with the Broncos, while out-of-favour Melbourne halfback Brodie Croft is reportedly bound for Red Hill.
News Corp said Brisbane may announce Croft's signing as soon as Monday, pending a release from the Storm.

David Cup: Andy Murray produces comeback to win on return to Great Britain action
by Press AssociationAndy Murray conjured up another miracle comeback to beat Holland number two Tallon Griekspoor as Great Britain defeated Netherlands in their Davis Cup Finals opener in Madrid.

The former world number one is playing in the competition for the first time since 2016 and his return to form and fitness had been seen as a major boost to Britain's hopes of challenging for the trophy at the inaugural finals week.
If that is to happen, Murray will have to improve significantly from a performance where he looked out of shape and rusty and was given a huge scare by an unheralded opponent ranked 179, who admittedly played well above that.
Crucially for Britain, though, the Scot's famous fighting spirit was very much in evidence and he battled back from 1-4 down in the deciding set to win 6-7 (7) 6-4 7-6 (5) after two hours and 51 minutes.
The deciding tie-break was a masterclass in extraordinary defence from Murray, who said: "It was a very, very tough match, fantastic atmosphere."
A sizeable contingent of British fans made the Caja Magica's third arena look and feel like a Davis Cup stage and Murray added: "I think that was one of the things that some of the players were worried about playing at a neutral venue but I thought the atmosphere was brilliant from both sets of fans.
"He played brilliant. I was lucky at the end of the match. He deserved to win."
There had been speculation that Murray may not play in this tie to rest him for harder matches but it soon became clear the question marks were in fact about his form.
The tie went go a deciding doubles rubber after Dan Evans was beaten 3-6 7-6 (5) 6-4 by Dutch number one Robin Haase.
Evans looked to be cruising at a set and a break up and served for victory at 5-4 in the second set but Haase broke back and an early break in the deciding set proved crucial.
Britain emerged victorious from the tie thanks to a 6-4 7-6 (6) victory for Jamie Murray and Neal Skupski over Wesley Koolhof and Jean-Julien Rojer.

It was a high-pressure occasion for Skupski, who has been partnering Murray on the tour since June, to make his debut but the Liverpudlian did extremely well.
Issues with the advertising screens flickering caused a couple of temporary delays - another example of the technological shortcomings that need to be addressed - but that did not detract from another compelling contest.
Murray and Skupski were on the ropes on several occasions in the second set but saved two set points in the tie-break before a run of four straight points earned them victory.
Another win for Britain over Kazakhstan on Thursday will book their spot in the last eight.
Elsewhere, Rafael Nadal's Spain eased into the quarter-finals on home soil while Novak Djokovic helped Serbia make a fast start to their campaign.
It was nearly 2am on Wednesday morning when Spain completed victory over Russia but they made much shorter work of a severely-weakened Croatia in the evening to send the defending champions tumbling out.
Croatia's chance took a major hit with the withdrawal pre-event of Marin Cilic, and they were also without Borna Coric on Wednesday.
Doubles specialist Nikola Mektic had to play singles against Roberto Bautista Agut, losing 6-1 6-3, before home hero Nadal saw off Borna Gojo 6-4 6-3.
While the main arena was again rocking for Spain's tie, it was a different story in the morning for Serbia's clash with Japan, but Djokovic shrugged off the lack of atmosphere in a speedy 6-1 6-2 victory over Yoshihito Nishioka.
That secured the most comfortable of victories after Filip Krajinovic had earlier beaten Yuichi Sugita 6-2 6-4, with the doubles team of Janko Tipsarevic and Viktor Troicki completing a 3-0 whitewash.
Djokovic, meanwhile, criticised the situation that emerged on Tuesday night when Canada were allowed to forfeit their doubles rubber against the USA having already won both singles matches.
That put the Canadians through to the quarter-finals but, with the two best-placed runners-up across the six groups progressing to the last eight, the 6-0 6-0 scoreline awarded to the US could help them in comparison to other teams.
Djokovic said: "I personally don't like that. That shouldn't be allowed. That 6-0 6-0 might make a big difference in the calculations for the second-best teams. So I don't think that's fair. I think everyone should be obliged to come out and play."
The International Tennis Federation said that Canada were permitted not to play the rubber because three of their four players were passed unfit.
Teams are allowed to have five players but Canada chose not to replace Milos Raonic when he pulled out through injury.
Germany sprang a surprise by beating Argentina 3-0 to give themselves a great chance of reaching the quarter-finals.
Philipp Kohlschreiber recovered from a set down to defeat Guido Pella 1-6 6-3 6-4 while Jan-Lennard Struff was a 6-3 7-6 (8) winner over top-20 player Diego Schwartzman.
Doubles pair Kevin Krawietz and Andreas Mies then won the longest tie-break in Davis Cup history, taking the deciding set 20-18 against Maximo Gonzalez and Leonardo Mayer.
