I am currently a student at the University of Virginia. I am studying Mechanical Engineering and minoring in design integration. Through this combination I have technical knowledge and hands on experience designing and building systems in interdisciplinary teams.
I also have also been able to explore my interest in web development.
The shortest path robot recieves a target destination through a webpage and uses Dijkstra's shortest path algorithm to navigate there as quickly as possible.The webpage takes an input of a letter, which represents a specific intersection on the course. Reflective sensors are used to ensure the robot stays on the lines and a wifi chip is used to recieve instructions from the database. My role on this project focused on structuring and writing the arduino code (C/C++) so the robot could handle different situations. The robot moved through different states depending on what event occured. For example, one state was of course driving.  This was determined from the output of dikjstra's algorithm, which was the order of intersections to progress through. It was then necessary to translate this list of letters into directions for the robot so the correct turns were carried out at intersections.
Close ProjectThe Smart Cat Feeder detects, dispenses, and presents food to the appropriate cat. Once the correct cat is detected through the use of RFID, a tray holding the food becomes available. The inspiration for this project is a multi-cat household in which the cats do not eat the same type of food. The entire product development cycle was utilized during the course of this project. Core requirements were defined from user engagement data and market research. Additionally, many rounds or prototyping occured. Starting with user experience prototypes of individual components and ending with the integration of all subsystems. In order to construct a functional system, we 3D printed dispenser components, used RFID for detection, and built a retractable tray with a re-purposed gear belt and stepper motor.
Close ProjectI am currently performing reserach at the UVA Aerospace Reserach Laboratory on the shock/expansion tube facility. My research focuses on evaluating the capabilities of the hypersonic wind tunnel that could be used to test spacecraft and high speed aircraft. This is being performed through the installation of computational flow software. Additionally, I am writing simulation scripts based off the physical properties of the wind tunnel to evaluate the performance envelope. Simulation values of speed and pressure will be compared to values from physical testing.
Close ProjectThis web application can analyze the tweets of public twitter users. It looks at the users last 200 tweets and displays the top 10 most used words. It also performs a sentiment analysis using google's natural language processing API. It displays the most postive and negative tweet and classifys what percentage of the tweets are positive, negative or neutral.
Close ProjectTickit is a service developed for a software company to handle complaints/requests from a client. Clients can log complaints and software engineers can resolve these complaints. The engineer logs the status in tickit so it is visbile to the client. The goal was to create a more transparent service between the client and the software company.
Close ProjectThe follow the leader robot uses PID control to stay a set distance behind the leader robot. It uses reflective sensors to stay on the line, IR sensors to recieve turn commands and ultrasonic sensors to determine its following distance.

The paper presents NeuroSAT, a message passing neural network that is trained to predict if a given SAT can be solved. As a side effect of training, the model also learns how to solve the SAT problem itself without any extra supervision.
Given an expression in the propositional logic, the task is to predict if there exists a substitution of variables that make the expression true.
The expression itself can be written as a conjunction of disjunctions (“and” over “or”) where each conjunct is called a clause and each variable within a clause is called a literal.
Invariants
The variables or clauses or literals (within the clauses) can be permuted.
Every occurrence of a variable can be negated.
Given the SAT problem, create an undirected graph of literals, their negations and the clauses they belong to.
Put an edge between every literal and the clause to which it belongs and another kind of edge between every literal and its negation.
Perform message passing between nodes to obtain vector representations corresponding to each node. Specifically, first, each clause received a message from its neighbours (literals) and updates its embeddings. Then every literal receives a message from its neighbours (both literals and clauses) and updates its embeddings.
After T iterations, the nodes vote to decide the prediction of the model as a whole.
The model is trained end-to-end using the cross-entropy loss between logit and the true label.
Permutation invariance is ensured by operating on the nodes and the edges in the topological order and negation invariance is ensured by treating all literals as the same.
The most interesting aspect of this work is that even though the model was trained to predict if the SAT problem can be satisfied, it is actually possible to extract the correct assignment from the classifier.
In the early iterations, all the nodes vote “unsolvable” with low confidence. Then a few nodes start voting “solvable” and then a phase transition happens where most of the nodes start voting “solvable” with high confidence.
The model never becomes highly confident that problem is “unsolvable” and almost never guesses “solvable” on an “unsolvable” problem. So in some sense, the model is looking for the combination of literals that actually solves the problem.
The authors found that the 2 dimensional PCA projections of the literal embeddings are initially mixed up but become more and more linearly separable as the phase transition happens.
Based on this insight, the authors propose to obtain cluster centres C1 and C2, partition the variables according to the cluster centres and then try assignments from both the partitions.
This alone provides a satisfying solution in over 70% of the cases when though there is no explicit supervising signal about how to solve the problem.
The other strengths of the paper includes
Generalizing to longer and more difficult SAT problems (than those seen during training).
Generalizing to another kind of search problems like graph colouring, clique detection etc (over small random graphs).
The paper also reports that by adding supervising signal about which clauses in the given expression are unsatisfiable, it is possible to decode the literals which prove the “unsatisfiability” of an expression at test time. Though not a lot of details have been provided about this part and would probably be covered in the next iteration of the paper.


The problem that I had while I was working on Javascript was that JS was completely new thing for me (and I still don't know fully how to use JS at this point). For instance I knew there was if else statement, for statement to use but I didn't know how.
First of all I tried to solve questions myself but because I had no idea how to solve the question myself I looked up on google, sometimes the answer it self so I know how JS works and then I trace back so I understand what the question is rather than just copy and pasting. I asked Harrison at the end because I really could not understand how JS work. It was hard but as Harrison adviced drawing how the Javascript might look like in the end visually helped me more.
It was like learning math (but not math) all from the beginning. You just need to get used to how JS works and because JS is more mechanical than visual.
Instead of trying to work on small contents first I need to know what JS function is needed to be used in order to make things work, for instance I need for function for some but in other JS I need if else function.
Not really.. JS is not like CSS I can't really see it visually before I make JS working beforehand. Although in order to count something I know I need to use for and in order to list something out and make things stop when the result has been given I need to use if else statement.
I am good at trying something but also breaking something as well. I am learning how to do console logging and I read error messages but I don't think I fully understand how to solve this yet. I am good at googling but I can spend ages doing this because I need extra explanantion. I think I am fairly confident asking coaches for help but I try not to because I have to try first before I reach out to them they are my last option. Asking peers and improving my process with reflection would be the weakness for me because I tend to have break if nothing works out for me but I know there are friendly and intelligent peers out there.

Very Lame VBScript page to show calling the TraceSrv DCOM Service.Special Note: If you configure TraceSrv to run through DCOM on another machine, Internet Explorer will properly create the TraceSrv object and you can call through it just fine. However, when you exit Internet Explorer 3.02 (4.70.1300), Internet Explorer will crash with a bad memory read at EIP 0x77A83450 on Intel machines at and address FP 0x776E6020 on ALPHA machines. The crash is in SECURITY.DLL. I have not tried this on Internet Explorer 4.0 betas.


@(transferDetails: Form[bankModel])(implicit request:Request[_],lang: Lang) @import helper._ @main("Bank Transfer") {
The Genuine Transfer includes a CSRF Token (Synchronizer Token) which play validates against the session. If the token matches then the request is legitimate and actioned.
<form action="/transfer?csrfToken=e6734770ca62e0456eb53cf670b55aeaf6c06bff-1454076319918-7a4b687ea285f4272d43c14f" method="POST" > Account <input type="text" name="Account" id="Account" /> Amount <input type="text" name="Amount" id="Amount" /> <button type="submit">Transfer</button> </form>

An attacker could try and create a hidden form like the one below, with a button that looks innocent enough. Because the attackers form does not include the CSRF token the server throws a missing token exception. Thus avoiding a malicious bank transfer to their account.

Curriculum Vitae
Steen Lehmann
Who am I?
I’m a CTO and Software Specialist for the Danish branch of Jayway, which employs some of the best software developers in the industry. We consult on all aspects of software development, and are owned 100% by the employees.
Since first discovering computers in the mid 1980s as a kid, I’ve been writing code in multiple platforms and languages. In the 90s I studied both computer science and human-computer interaction, enabling me to design and build things that are elegant and simple, inside and out.
I take a keen interest in agile/lean ways of working, how teams perform, information and interaction design, software architecture, operations, and much more. Shortening the feedback loop, on all levels, evolving and molding systems until they solve the right problems for the right people, and no more.
I’m responsible for technical interviews when we recruit sociable geeks.
I’ve been a speaker (and am part of the program committee) for Øredev, the largest developer conference in the Copenhagen-Malmö area, most recently in 2013 on making enterprise apps more fun and enjoyable, using UX conventions from touch interfaces and information design.
First and foremost I am a geek at heart, enjoying creating software that is both useful for people, and structured in a clear way.
The work I most enjoy is building delightful web applications that enable users to create or discover something new, by visualizing information in dynamic and novel ways. Due to my humanities background I can pull in inspiration from many different fields like the visual arts, and thanks to my geeky technical side I can then build everything myself.
Employments
CTO & Software Specialist
Since being employed in 2006 as the first Danish employee, I’ve done consulting on most areas of software development and architecture. I do technical interviewing for potential hires, help arrange our conference Øredev, and try to keep up-to-date on contemporary technology.
Some of the clients I’ve worked for during my years at Jayway include:
- Sony Ericsson (Xperia Lounge Voucher Server - Java architect)
- TrueSec (Java architect/developer)
- Cloudfinder
- 3 (3Switch)
- Politiken (Release Management, front-end development)
- Polfoto (front-end and back-end development)
- Ekstra Bladet (EKSTRA, eBladet - front+back-end development)
- WATCHME (EU Project, http://www.project-watchme.eu/)
- INMOTOS (EU Project through AmanziTel, see later)
- BoB / KPerson (internal tools for resource planning at Jayway)
- European Communications Office
Software Engineer Consultant
Although I joined the small startup Wapportal in 2000, back when WAP was the next big thing for mobile, we soon found ourselves engulfed by first SilverStream Software, and then a year later by Novell. This was around the time Novell acquired lots of interesting companies like SuSE Linux and Ximian Desktop. We ended up a sort of skunk works, mostly building XML-based Eclipse tooling products for Novell’s line of identity management products. I ended up having implemented, among other things, the XML Schema standard, for use in an innovative XML editor. Our Danish development office was finally shut down in late 2005.
Applications Consultant
My first job was with TIBCO, where I spent most of my time at Danske Bank HQ in Holmens Kanal, developing market data displays for traders, and supporting their TIBCO message bus installation. It was an intense experience at times, where I learned to think on my feet. I became friendly with the principles of real-time information display to support challenging business requirements, and UNIX command-line tools. I helped manage servers spread over more than 20 sites, performing upgrades and diagnosing networking issues.
For 4 months in 1999 I worked on-site on a project in Zürich for Credit Suisse Private Banking, where I supported the back-end system for youtrade.ch, an online trading system for private customers in Switzerland. I was a key part of the TIBCO support team, responsible for keeping the system running 24/7, and performing upgrades at pre-scheduled times in the night.
Education
B.A.
I studied Computer Science at Århus University for 3 years before switching majors to Information Science, a humanist approach to computing. This has given me a solid background in core computer science, as well as an understanding of the human factors in computing. I reached the point where I could start my Master’s Thesis, but instead decided to start my first job.
Selected experiences
This section highlights some of the more visual projects I’ve been a part of.
EKSTRA
Digital Subscription Plan for Ekstra Bladet.
Ekstra Bladet needed a lot of different systems to come together in order to launch EKSTRA, a critical project for their business, which for the first time would require readers to become subscribers, in order to see extra content on the site, Denmark’s busiest web site.
I was responsible for integrating the existing Single Sign-On system (also developed by Jayway) with a third-party subscription system and a third-party payment service. The designs for sign-up flows for both new subscribers and existing customers had to be implemented into the existing content management system (from another third party), as did forms for letting customers maintain their accounts.
KPerson
Competence database for Jayway.
KPerson, an internal tool at Jayway, was built in 2008 by me and a couple of other consultants at Jayway as a Rails 2 application, then maintained and upgraded by me over the next 7 years. It is now a Rails 4 application based on the Bootstrap CSS library, making it responsive for phone and tablet use.
KPerson is a database of each consultant’s background and skills. Consultants are required to update their skills and experiences, and our sales people use the information to search for consultants suitable for incoming assignments, then automatically generate and download PDF resumes in the correct format.
INMOTOS
Interdependency Modelling Tools and Simulation Based Risk Assessment of ICT Critical Infrastructures Contingency Plans
For the INMOTOS project, I was tasked with converting a large number of requirements and specifications into a working prototype able to simulate complex infrastructure such as power plants and pipelines. I decided to use Coloured Petri-Nets, a visual programming and modelling tool, creating an implementation in Ruby Open sourced in 2012. The simulation front-end was a JavaScript application which used websockets to display a live view of the simulation in-browser, complete with development tools. It used the Raphäel library to display SVG-based graphics Demonstration video at https://www.youtube.com/watch?v=riLWVf_3BOQ.
Conclusion
As is clearly apparent from the graph below, I have improved constantly since starting my professional career in 1997. I am now able to tackle problems in a few days that would have taken me weeks fresh out of university. Due to my extensive experience with different technologies, I can design user interfaces, evaluate and use new JavaScript frameworks and libraries at roughly the rate at which they are produced, build server-side APIs and deploy them on cloud based infrastructure, and much more.

Denys,
When I try to build the 0.22 version I have a problem with
gecode-common.icc at line 422 with the flush function that doesn't seems
to be recognized.
If I comment the line the code compile fine.

This post outlines some business considerations for open source. It follows advice Infonomics provided to the World Wildlife Fund in collaboration with Ribble Consultants.
Open Source Definitions
The term open source denotes software for which the original source code is made available and may be redistributed with or without modification. In practice this is typically coupled with a peer-production development model although code can be open-sourced without providing any means of re-integrated changes back into the code base. Note that:
- Free software is not necessarily open-source (closed-source software may be free). Here ‘free’ refers to the freedom (to run, modify, and redistribute) not the price.
- Open-source software is not necessarily free of charge. There are a variety of business models for generating revenue from an open-source project including: ‘freemium’ (premium features must be paid for), consulting (selling services related to the product), support (paid-for training), subscriptions (original is free, updates require a fee), proprietary add-ons (fees for implementing/ developing bespoke features), and dual licenses (whereby only those earning money from the tool must pay).
- Open-sourcing does not necessarily involve any loss of control over the quality or integrity of the product (or intellectual property); multiple versions (internal and external) may exist concurrently. Typically derivatives and modifications are made upon ‘forked’ copies (or branches). The lead maintainer (person managing the code) takes responsibility for the core (trunk) version. Changes contributed by the community (in branches) may be applied (used to patch) the original (trunk) or they may be pursued independently. Moreover forks may pursue entirely different objectives without ever being integrated (e.g. a version is developed for a different software platform or only small portions of the code taken for use elsewhere). See below for some real-world examples.
Advantages and Disadvantages
The advantages of open source include:
- Bug/ defect correction: with more people exploring and testing the code there is a greater chance that problems will be identified and solved (improving stability and reliability);
- Improvements/ new feature: there are more people to contribute ideas and code to enhance the product and integrate it with other developments;
- Credibility: greater transparency lends credibility (‘auditability’) and the product’s sustainability depends less on the original developer. The disadvantages include:
- Price ceiling: the original developer may not be able to charge as much for software licenses. We might expect that the fee could be no greater than is the cost of deploying/ implementing/ maintaining the code that is provided.
- Intellectual property: other developers may be able to implement competing versions (this is typically dealt with via licensing restrictions).
Open Source Business Models
The table below describes how some of the larger businesses make money while releasing open-source versions of their software. Typically there is:
- a distinction between a limited-spec version which is released open-source and a fully-featured version which is sold commercially; and/ or
- a fundamental division of functionality along the lines of free to use, pay to develop/ sell;
- a set of complementary services that are provided at a fee (training, support, consultancy).
| Company | Open Source | Commercial | |
|---|---|---|---|
| Adobe | Flex platform for rich internet applications | Flash Builder integrated development environment | |
| Apple | Darwin: core unix compatible operating system released under Apple Public Source License | Mac OSX, Apple TV, iOS (iPhone/ iPad/ iPod platform) | |
| Canonical | Ubuntu: linux operating system | Technical support contracts | |
| Mozilla | Firefox: web browser | Partnership with google and others for including search engines in Firefox | |
| MySQL | Database: community edition | Enterprise/ Cluster editions, training and consultancy | |
| Sun Microsystems | Open Office: office productivity suite | Star Office |
What to consider before going Open Source
- Release the code: the source will be made available online (i.e. the code not necessarily the data)
- Release data: some example data may be provided
- Provide facility for commits: developers may ‘commit’ changes or ‘fork’ new versions of the software (otherwise developers are responsible for maintain their own – external – versions)
- Allow derivative works: software developed from the tool can be sold commercially (there may be dual licenses – i.e. one for users and another for re-sellers)
- Modifications must distribute source: Licensee must include the source with any modifications (i.e. cannot create a closed-source derivative)
- Derivatives subject to same license (copy-left): require that the same rights be preserved in modified versions
- Provide user support: for example, via training courses/ email/ telephone/ issue tracking/ webchat to end-users
- Provide development support: as above but for developers
- Facility for community discussions: a popular alternative to one-to-one support, this allows users to guide one-another (typically moderated by trust users or employees)
- What aspects are free of charge?
- What aspects require a fee?

Deroy Murdock: Where are the high crimes and misdemeanors to justify impeaching Trump?
by Deroy MurdockThe Constitution is quite clear: The president "shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors."
Democrats are speeding toward the impeachment of President Trump with this standard barely a pebble in their path. Democrats regard President Trump with uncontrollable, pathological, stammer-inducing hatred and are determined to impeach him, no matter what.
CLICK HERE TO SIGN UP FOR OUR OPINION NEWSLETTER
The House this morning voted 232-196 to formalize these proceedings, now with a daisy petal of due process that the White House is welcome to use in the president’s defense. Zero Republicans voted for this impeachment resolution. Unlike the multi-party votes in favor of opening impeachment actions against presidents Clinton, Nixon, and Andrew Johnson, House Speaker Nancy Pelosi of California and all but two Democrats voted to begin the effort to unseat President Trump with no backing whatsoever from the president’s own party. Thirty-one Democrats joined Republicans to launch impeachment against Democrat Clinton. Nearly every Republican opposed Nixon when the House voted 410-4 to begin efforts to dislodge him.

What a dark, unprecedented day in American history.
Still, the question remains: How, exactly, is Trump even accused of "treason, bribery, or other high crimes and misdemeanors"?

Opposition in Georgia vows further anti-government protests
TBILISI (Reuters) - Georgia’s opposition plans further anti-government protests and will demand an early parliamentary election, its leaders said on Tuesday, a day after police dispersed demonstrators in the capital Tbilisi.
Police used water cannon to scatter the protesters outside parliament on Monday and unblocked entrances to the building, arresting 37 people. But hundreds of protesters re-assembled in front of parliament on Tuesday evening.
“Our protest will continue until the resolution of the crisis that Ivanishvili created in the country,” David Bakradze, leader of the European Georgia party, referring to ruling party leader Bidzina Ivanishvili, an oligarch who critics accuse of ruling the former Soviet republic from behind the scenes.
The protests began last week after parliament failed to approve a planned electoral reform - a move to full proportional voting from the mixed system at present.
The switch was scheduled to happen in 2024, but the opposition demanded it be brought forward, saying the system unfairly favors the Georgian Dream party, which has ruled since 2012.
Bakradze said the opposition’s actions would be non-violent, although he did not rule out blocking entrances to parliament again next week.
Protesters also demanded the release of the 37 arrested for blocking parliament on Monday. A Tbilisi city court postponed hearings on their cases.
Prime Minister Giorgi Gakharia said on Tuesday blocking entrances to parliament was illegal. “Freedom of expression in the country is fully protected by law, but in case of illegal blocking of the state institutions, the police will act within the law...,” Gakharia told reporters.

Intro
In this inaugural post, I’ll introduce myself, explain my motivations for creating this blog, and list some topics of interest that I intend to post on in the future. My goal is to do roughly one post per month.
To borrow and amend a phrase from /This American Life/, this blog acknowledges the existence of human-induced climate change. This will largely be taken as given; there are many other places online to find flame-wars on the topic. I have enabled a comment system, which I will moderate as necessary to keep discussion on topic and civil.
Who I am
I am a postdoctoral scientist at the Lamont-Doherty Earth Observatory of Columbia University. I did my Ph.D. work in the Program in AOS at Princeton University, where my adviser was Dr. Yi Ming.
Why this blog
There are several existing blogs on weather/climate that I recommend, all of which by scientists with much more expertise than me.
Nevertheless, as evidenced by the list of topics below, I will span a broader range of topics than any of the existing blogs do. I hope that this will create a rich space, but given the hyper-specific combination of interests, there is a danger in this becoming a purely self indulgent exercise.
Topics
- Constraining past and future hydrological changes
- The climate science software toolchain
- Open science, reproducible research, etc.
-
Climate and weather in music and other media
I am slightly obsessed with music.
-
Science outreach and K-12 education
I am currently working with Jon Aurnou and other collaborators at UCLA on a build-it-yourself rotating table platform for conducting demonstrations of rotating fluid dynamics, which are central to the dynamics of Earth’s atmosphere, ocean, and interior as well as the atmospheres of other planets.

Six migrant bodies washed up on Libyan coast
TRIPOLI (Reuters) - The bodies of six migrants were washed up on the coast east of Libya’s capital Tripoli on Friday, while about 100 survivors were brought back to shore, coastguards and U.N. officials said.
The bodies were washed ashore near al-Khoms, where there have been regular departures of boats packed with migrants trying to reach Italy, despite a sharp drop in overall crossings from Libya since mid-2017.
Those who died may have tried to swim from the boat on which the survivors were found, since it broke down and the migrants were in need of help, a coastguard official in Khoms said
The survivors were from sub-Saharan African countries and included three children and 10 women, one of whom was pregnant and gave birth during the rescue operation, the official said.
They were not detained and left the port of their own accord, he said.
Migrants intercepted by Libya’s European Union-backed coastguard used to be routinely detained on arrival, but recently several detention centers have been shut and large groups of migrants have been let go.
However, 30 of the group brought back to Khoms returned to the port shortly after leaving because they heard shooting near a local market and were afraid, the coastguard official said.
Rights groups have strongly criticized EU-backed efforts to curtail migrant crossings from Libya, including support for the local coastguard.
Migrants returned to Libya face widespread abuse including torture, forced labor and sexual assault, as well as risks from a military conflict that has escalated around Tripoli since April, activists say.

I thought I'd make note of wsgikit.config, a configuration loader. I haven't actually started using it in WSGIKit yet, but I've been using for the configuration of this blog. It has a few features that set it apart from some of the others.
It uses .ini syntax, an easy syntax to work with.
Values are not typed. That means you don't have to use "localhost" for a string, or ["admin", "user"] for lists. The application interprets the strings how it chooses, not based on syntax the user has to learn.
It keeps track of files and line positions, so when you coerce that user-provided string to a certain type (e.g., list of strings, boolean, domain name, etc) and there's an error, you can tell the user exactly where the erroneous data came from.
You aren't bound to a section/key structure, unlike normal ini-file parsers (like ConfigParser). When you use dotted names, that indicates that keys go in sub-dictionaries. Section names are just prefixes for the keys inside them. Lastly, parenthesis can be used to avoid the special meaning of . (useful with domain names), and to avoid normalization (non-alphanumeric characters are ignored, including space and underscore). So these are equivalent:
security.admin.users = tim bob jan # equivalent to: [security(admin)] users = tim bob jan
In addition to layering several files (e.g., a user and site config file) you can also merge sections of a config file on top of another config file, including on top of itself. This allows configurations similar to an Apache <Location> tag, where config values are looked up based on contextual information.
Though not supported now, everything is in there to do round-tripping, i.e., where you load a config from disk, change some settings (e.g., through a web interface), then save the config back, trying to preserve what extra information (like comments and ordering) that it can.
Big to-do's:
If you're curious, the lazyloader module is the place to start looking.
Ian wrote:
Better syntax for nested options than config[section][key]I ran into the same issue. In my config format, I found that I never needed a depth greater than 2, so the following works pretty well (as a method of the Application object):
def config(self, branch=None, leaf=None, default={}): """config([branch], [leaf], default={}) -> tree, branch, or leaf. If branch is not specified, the entire config dict is returned. If branch is specified, but leaf is not, the requested branch is returned (or default if it does not exist). If branch and leaf are specified, the leaf value is returned (or default if either the branch or leaf does not exist). In the case where either branch or leaf are not found, the config tree is not modified--you simply get back empty or default values. """ if branch is None: return self._config if leaf is None: return self._config.get(branch, default) return self._config.get(branch, {}).get(leaf, default)I don't think it would be too hard to convert to n-depth.
# Robert Brewer
I was thinking of allowing either a sequence of keys, like config[section, key] or config.get((section, key)), or maybe somehow allow dotted names, like config.get('section.key') (since usually these are constants anyway). But sometimes I do want keys that contain dots, so it's not a complete plan.
Might users find it more consistent if dots were always required between name components - e.g. admin.(stuff) - rather than being omitted when the component is quoted with brackets? Quoted fields in a CSV file are still delimited by commas even though the field boundaries could be inferred from the quotation marks alone.# Hamish Lawson
Dots are allowed in those positions, but I don't like the way they look, so they aren't required.

Re: Your Kind Attention Needed Dear Friend, My name is Mr. Chris Swales and I work with a Bank here in London-England, The name of the bank is Barclays Bank. We had a Mr.Allen Duke, customer that had a deposit of US$4.8M (Four Million Eight Hundred Thousand United States Dollars) before he died in a plane crash with his wife and only Child about 6years now (January 30, 2000) and since he died, we in the Bank here have been expecting his/her next of kin/relative(s) for the inheritance of the deposit, but none has surfaced. The policy of the Bank however stipulates a limited time period for such inheritance to be made or the fund will be written off going by the record of the incident, the time limit for the claim is closing up. In this consideration, I am contacting you to seek for your kind understanding and sincere co-operation to claim this inheritance for our mutual benefit. If you can stand as the next of kin in this project, success is assured because I am in possession of the personal file jacket of the deceased which contains every needed information about the account and the deceased. You and I stand no risk of any kind because I have enough information to support you in claiming the inheritance. The proceedings of the transaction will be shared 50% each after expenses are reimbursed. Kindly indicate your willingness by email on<EMAIL_ADDRESS>and we shall proceed with the initial step for the claim. The entire project is expected to last for about ten working days. Please kindly get back to me urgently so that we will discuss more on this issue. Also do not fail to furnish me with your direct phone and fax numbers for easier communication. Best Regards, Chris Swales Email:chriswales@katamail.com

Around half of clients in mental health services will have a child (Seeman & Gopfert, 2004).
These children are at increased risk of mental health difficulties themselves, partly for genetic reasons, but also because of environmental ones.
Supporting parenting in those with mental health difficulties can both reduce the risk of children developing difficulties and improve the welfare of the parent (Berg-Nielsen, Vikan and Dahl, 2002).
The Flourishing Families Clinic aims to provide support to parents seeking treatment for mild to moderate mental health difficulties by providing parenting support. With this support we aim to improve parental mental health and, ultimately, the well-being of the child.


Wow! Talk about extremely relaxed. Right now I don't have a care in the world. My back and neck muscles have been bothering me all day, from a car accident 5 years ago. I decided to take 2 Soma and chase it with a few shots of Crown Royal.
Right now the room is spinning, in a good way. Very relaxed. I could go to sleep right now, and feel like I could sleep for days. Every muscle in my entire body is so relaxed you could hit me with a sledge hammer, and I would grin at you and ask for another.
The phone just rang. It's the Catholic prayer line asking me to pray for a lady from our parish who is very sick with cancer. I told them with slurred speech that I would not only pray for her but for everyone who ever had cancer, both present and past. I also told the person that I would even pray for everyone in the world who may be diagnosed with cancer in the future. Further, I told her that I would pray for people on other planets that might come down with cancer. I told her that cancer would top my prayer list for the next several years. Wonder why she ended the conversation so abruptly? Does she suspect that I feel stoned? ;)
Empirically speaking, my mind feels fuzzy. Like when one first wakes up from anethesia or just before sleep overtakes someone. I have to constantly correct my spelling as I type this since my fingers are so relaxed and are randomly hitting the keys. Hearing is very acute. I can hear a pin drop about now. Thoughts are random, scattered, and tangential at best.
Nothing euphoric like the effects of THC. Body feels heavy. Like I weigh 800 pounds. Rocking and bobbing my head are pleasurable. I feel like one of those Weeble Wobbles from the 70s ('Weebles wobble but they won't fall down'). Getting ready to watch some television. Overall, the sedative qualities of Soma are magnified with alcohol.
No introspection noted. Hell, I don't even feel like thinking about anything right now, except perhaps the couch and an old movie to lull me to sleep. Only side effects noted are unbalance and slurring.

Thus far in my DBC experience nothing has been as difficult for me to wrap my head around as arrays. Maybe iteration, but ignore that. This week in crazy programming adventures is HASHes (eheheh) and arrays too. -cue intro music- The easiest way to understand an array is to think about it as an ordered list. Imagine being able to tell Ruby, "Hey Ruby store these things in order in something". Just like that you've got a numbered list of items that ruby will keep track of and you can access whenever you want. You've got an array. I always think of arrays as a straight line with data in slots along a number line, kind of like a storage unit you rent. All the units are lined up by number and each individual storage unit is an index. A hash on the other hand is more like a dictionary instead of an ordered list. You tell Ruby, "Hey I have these keys that I want you to store values in. For "Cheese" I want you to remember cheddar and for "Dog" I want you to remember Duchess". Now you have a hash. Instead of keeping items in an indexed list like an array, a hash keeps things organized by keys that you define as the programmer. It makes keeping data of non listed items much easier. In all seriousness both hashes and arrays are both very similar in that the both store data, the real difference is only in how it arranges them and then semantically how you access them. Both could be used for the same goal but are going to be structured differently. The crux is really finding which is the best to use for your problem at hand.

Stencila is still in early beta testing phase. Like the rest of the platform, this introductory manual, is a work in in progress. Please feel free to contribute via our Github repo. Or, chat with us in our Gitter room.
Introduction
Stencila aims to make it easier for researchers to do reproducible research. Stencila Documents are like Microsoft Word or Google Docs documents but built from the ground up to fit with reproducible workflows. They allow you to embed code, in various programming langauges, within the document so that you can rapidly update your tables and figures - and so that others can see how you produced them. Stencila Documents can be stored using plain text formats like Markdown that work well with version control systems like Git. They can also be exported to publishing formats such as HTML (and in the future JATS and PDF).
Compared to other popular tools for reproducible research such as Jupyter Notebooks and RMarkdown, Stencila Documents aim to have an interface that is more similar to the the familiar interface of a word processor and allow you to produce polished final documents.

Code cells in Stencila Documents use a simple expression language called Mini. Mini is meant to be only slightly more advanced than the expressions that you write in your calculator or into the cell of a spreadsheet. It is intended to be easy to write and easy to understand.
Mini is implemented in JavaScript - so it can run in a browser without the need for external processes. But, as we'll see later, you can also extend it with other languages suchas R, Python and SQL.
Mini has a simple type system that is similar to most high level languages. Each type can be constructed using literals...
| Type | Example literal |
| null | null |
| boolean | true, false |
| integer | 1, 2, 42 |
| float | 3.13 |
| array | [1, 2, 3] |
| object | { a: 1, b: '2'} |
| my_custom_type | { type: 'my_custom_type', ...} |
Custom types can be defined using an object with a type
property e.g. { type: 'my_custom_type', ...}.
You can get the type string of a value using the type
function e.g.
Loading data
Tabular data is an essential part of data analysis, so there is a special type called a table.
The easiest way to create a table is by using the csv
function which parses a string of comma separate text (in the future you'll be able to embed or link to your data more concisely that this!)
Summarizing data
We're working on various functions for summarising and manipulating data (inspired by the approach of dplyr, the R package). But for now, there is just one function for that: filter,
which takes as input a data table and an expression describing the filtering criteria (for now the expression is a string, but in the future it will be a Mini lambda expression).
Plotting data
At present, a few functions are available for creating simple plots. The implementation of these is currently based on Vega-Lite, a high level grammar for visualization rendered using D3.js.
The core plot
function takes a data table, a mark name e.g. points, bars, and the names of columns in the data to encode into various plotting channels e.g. x, y, size, color. Let's create a simple scatterplot of our data:
There are also shortcut functions for using various plotting marks directly. Here, use the points
function and encode species name using point colors. We also use the options parameter (a Vega-Lite spec) to set the title of the legend:
But that syntax can be unweildly, so instead you can use the forward pipe operator |
and convieniece functions like titles
to set options.
Using other languages
An important feature of Mini is its ability to interoperate with other languages. Mini can act as a glue language - for those times when you need to combine the strengths of several languages. For example, you might want to extract some data from a database using Structured Query Language (SQL), then perform a specialised statistical analysis on the data using R, then visualise the results using Mini's built in plotting functions.
Mini makes this possible through alternative execution contexts. Each context knows how to convert values to and from the Mini value types and how to execute snippets of code in the context's native language. The JsContext
(for executing JavaScript code) comes embedded in the browser or desktop window of your Stencila Document.
Within the browser window of a Stencila Document there is a Stencila Host. A Host is responsible for finding, and talking to, other Hosts and orchestrating parts of the platform. Every few seconds, your browser-based Host looks for other Hosts being served within other processes running on your computer. (In the future you'll also be able to manually register both local and remote peers.) When a peer Host is found, a handshake is performed and the hosts exchange manifests of their capabilities. One of those is capabilities is a list of the classes of Stencila Contexts that the Host supports.
Stencila Contexts share a common interface for executing code, whatever the language. They are very similar to Jupyter's kernels (a Stencila Context for bridging to Jupyter kernels is planned). The Stencila language packages each have one or more class of Context. The following subsections provide instructions on how to download those packages and start the Host so that you can start using those contexts.
Node.js
Install the Stencila package for Node.js via NPM, npm install -g stencila-node
, then start the host by running stencila-node
in the system shell. If you've done that, this cell should show the Node.js version that you are running (if you need to, press Ctrl+Enter
within the source of the cell to refesh it)
return process.title + ' ' + process.version
Python and SQL
Install the Stencila package for Python,
pip install --user https://github.com/stencila/py/archive/master.zip
Then install the package's manifest so that it can be found by the Stencila Desktop and Stencila packages for other languages,
python -e &quot;import stencila; stencila.install()&quot;
If you've done that, this cell should show the Python version that you are running:
import sys return sys.version
The PythonContext
supports autoconversion between data tables and pandas.DataFrames.
So, for example, we can replicate the above plot using Pandas:
return data.plot.scatter(x='sepal_length', y='sepal_width')
The Python package also has a SQLiteContext
for executing code within SQLite. The SQLiteContext
support autoconversion of data tables. So we can pass it some data and it will
SELECT species, round(sum(sepal_length)/count(*),2) AS mean_sepal_length FROM data GROUP BY species
R
Install the Stencila package for R using devtools,
devtools::install_github('stencila/r')
Then install the package's manifest so that it can be found by the Stencila Desktop and Stencila packages for other languages,
Rscript -e 'stencila::install()'
The RContext
supports conversion of common types including R data.frames
as well as base and ggplot2
plots. So if you've got a R context running and have ggplot2
installed this cell will output the equivalent of the previous plot:
ggplot(data,aes(x=sepal_length, y=sepal_width, color=species)) + geom_point()
External languages
When you run an external language the code is executed within a local function scope. That means that any variables that you declare within that function are local to the function and won't leak into the context's global scope. For example, when you type py()
into a cell, your effectively saying to Mini, take this Python code, make it into a function, execute the function, and give me back the value. Here's an example of a simple Javascript cell:
let names = ['Hiphop', 'opotamus', ' v ', 'Rhyme', 'noceros'] return names.join('')
Notice that because we ended the JavaScript code, with a return statement that the cell has an output.
Just like with other Mini cells, you can assign the output of a Javascript cell to a document variable,
return Math.PI
A call to another language is not very useful unless you provide it with some data. This is where Mini's glueing comes in. Let's create an array in Mini,
and then use Javascript to join it together.
return 'My favourite fruits: ' + fruits.map((fruit,index) => { return `${index + 1}. ${fruit}` }).join(', ')
The nice thing about this is that Mini's dependency analysis still works, so you can change the fruits array and the output above will change - try it!
Notice that our Javascript function got supplied an argument called fruits - which is the same array of strings as in our document variable called fruits. You can also provide named arguments to the js function call.
return my_favourite_fruits[index]
The global
keyword
The global
keyword forces execution within the context's global scope. Using the global
keyword is very similar to using code cells in Jupyter notebooks or code chunks in RMarkdown. When you assign a variable within the cell it is available to be used within a different cell later in the document. However, you need to take care of dependencies yourself, so if you change the source code of the first cell, you need to re-execute the second cell that depends on it.
Here's an example. Let's assign a global variable within a JsContext
:
myGlobal = 45
Now, myGlobal
is a data/time object that is available to use in any cell. Let's look at it using another cell:
myGlobal
Play around with those two cells and note that when you change the first, you need to re-execute the second to see the new value for myGlobal
.
Putting it together
Here's an little example, that puts this all together with an input, a Javascript cell and an output to display the result...
The area of a circle can be calculated by a = pi r^2 . So, if the radius of a circle is m, then it's area is: m2.
return Math.PI*Math.pow(r, 2)
Now lets make thing interesting by manipulating, analysing and visualising the iris data using a combination of languages in a pipeline. This is a trivial, illustrative example, and it could all be done in one language but,..well, it's an illustration. It will only work if you have both the Python and R packages running as described above.
As a first step in the pipeline, let's filter and aggregate the iris data using SQL and an input variable min_petal_length
: .
SELECT species, sepal_length, sum(sepal_width) AS sum_sepal_width, count(*) AS num FROM data WHERE petal_length > ${min_petal_length} GROUP BY species, sepal_length
Then let's visualise that data table in R using the smooth
variable (defined in the figure caption) to control the span of the smoother applied.
ggplot(data_summary, aes(color=species, x=sepal_length, y=sum_sepal_width/num, size=num)) + geom_point() + geom_smooth(span=smooth) + labs(x='Sepal length', y='Sepal width')
Figure 1. Mean sepal width versus sepal length for each species when petal length is greater than or equal to . Smoothing span .


I use imagination, drawing, writing, design tools, and code to solve business problems with software solutions.
Product development is an ongoing cycle of identifying problems and opportunities, exploring solutions, shipping to real people, listening to feedback, iterating, and measuring results. This is how I work.


ghc-datasize is a tool to determine the size of Haskell data structures in GHC’s memory. Determining the size of recursive data structures is supported. All sizes are in Bytes.
1. Installation
The package is available on Hackage. Install it like this:
$ cabal install ghc-datasize
If you want to make sure you get the newest version of ghc-datasize update your cabal database before:
$ cabal update
2. Usage
Now you can run ghci and experiment with ghc-datasize:
$ ghci
GHCi, version 7.6.3: http://www.haskell.org/ghc/ :? for help
λ> import GHC.DataSize
λ> recursiveSize 3.3
16
λ> recursiveSize 'a'
16
λ> recursiveSize (1,2,3,4)
104
λ> recursiveSize True
8
λ> import Data.Complex
λ> recursiveSize $ 2 :+ 3
248
For data structures that are not yet evaluated the size of the unevaluated structure in memory is calculated. To make sure you get the size of the resulting data structure, you have to force evaluation to Weak-Head Normal Form (WHNF):
λ> recursiveSize $! 2 :+ 3
56
λ> recursiveSize $! (3 :: Int)
16
λ> recursiveSize $! (3 :: Integer)
16
λ> recursiveSize $! (2^64 :: Integer)
56
λ> recursiveSize $! (2^128 :: Integer)
72
λ> recursiveSize $! (2^1024 :: Integer)
184
λ> recursiveSize $! "foo"
88
λ> recursiveSize $! "foobar"
88
For composite data structures evaluation to WHNF is not enough. In the list "foo" only the first element, f, was evaluated, while the rest of the list stays unevaluated. To get the size of the fully evaluated data structure a deep evaluation has to be forced:
λ> import Control.DeepSeq
λ> recursiveSize $!! ""
8
λ> recursiveSize $!! "foo"
128
λ> recursiveSize $!! "foobar"
248
λ> import qualified Data.ByteString.Char8 as B
λ> recursiveSize $!! take 1000 $ repeat 'X'
24024
λ> recursiveSize $!! B.pack $ take 1000 $ repeat 'X'
1072
Strings are quite memory intensive, taking 24024 Bytes to store 1000 8-bit Chars. ByteStrings are much more memory friendly, taking only 1072 Bytes for the same data.

Linked Data can be published and accessed on the Web in a variety of ways. This document specifies the Triple Pattern Fragments interface, designed for low-cost Linked Data publishing and efficient client-side execution of several common types of queries. Each Triple Pattern Fragment contains those triples of a dataset that match a specific triple pattern, together with the estimated total number of matching triples, and hypermedia controls to find all other Triple Pattern Fragments of the dataset.

Linked Data [[LINKED-DATA]] consists of structured links between pieces of data.
For example, we can link the concepts “Thomas” and “Nikola”
with a “knows” relationship: Thomas knows Nikola
.
Yet this alone cannot be interpreted unambiguously.
Which Thomas and Nikola are we talking about?
And what does “knowing” mean in this context?
We use URLs to clearly and unambiguosly identify each of those three pieces of information:
<http://dbpedia.org/resource/Thomas_Edison>
<http://xmlns.com/foaf/0.1/knows>
<http://dbpedia.org/resource/Nikola_Tesla>.
If you, or a machine, want to know which “Thomas”, “Nikola”, or “knows” is mentioned, you can simply follow their URLs. This is the essence of Linked Data, and the above snippet depicts a Linked Data triple in the RDF model [[RDF11-CONCEPTS]]. RDF data exists in various concrete syntaxes:
Just like HTML, RDF is simply a format for documents—publishers can choose freely how they divide data across different documents. Each server determines which interface it chooses to offer Linked Data. Some of them might publish a few large documents with millions of triples, others might give access to very specific, on-demand parts of a dataset. In order to communicate with each other, clients and servers can reuse agreed-upon interfaces, each of which comes with its own balance of advantages and disadvantages.
The goal of a Triple Pattern Fragments server-side interface is to provide low-cost access to Linked Data, and enable efficient live querying over the dataset on the client side.
This document defines Triple Pattern Fragments, a Linked Data Fragments type, by specifying their representation and effect on the application state. This allows to publish and consume Linked Data through a Triple Pattern Fragments interface.
This document is intended for people who want to implement a client or server of Triple Pattern Fragments, or for those who want to understand how such clients or servers work.
We write triples in this document in the Turtle RDF syntax [[!TURTLE]] and use the following namespace prefixes:
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX hydra: <http://www.w3.org/ns/hydra/core#>
PREFIX void: <http://rdfs.org/ns/void#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
In essence, every client–server interface is characterized by two components:
These essential design decisions also determine Linked Data interfaces, through which a server publishes RDF triples from one or more datasets. Each Linked Data interface answers the above two questions differently.
The Triple Pattern Fragments interface, which is defined in this document, answers those questions as follows:
A Triple Pattern Fragment contains all triples from the interface's dataset that match the requested triple pattern, together with metadata and hypermedia controls. The remainder of this section precisely defines Triple Pattern Fragments and their components using the Linked Data Fragments conceptual framework.
The Triple Pattern Fragments interface consists solely of the definition of the Triple Pattern Fragment document type. No protocol-specific details are specified, since each Triple Pattern Fragment contains hypermedia controls that explain in-band how clients can engage in an interaction through a specific protocol. This means that, given one Triple Pattern Fragment, a client can consume the entire interface. As an example, the application of Triple Pattern Fragments to the HTTP protocol is detailed in .
A Triple Pattern Fragment is a Linked Data Fragment [[!HYDRA-LDF]] of a dataset that consists of three parts:
?subject ?predicate ?object.
”.
void:triples
predicate
that expresses the estimated total number of matches for the triple pattern.
A Triple Pattern Fragment of a dataset is fully determined
by its triple pattern selector.
In its most abstract form,
a triple pattern selector consists of three components
subject
, predicate
, and object
[[!RDF11-CONCEPTS]].
The subject
MUST either be a variable or an IRI;
the predicate
MUST either be a variable or an IRI;
the object
MUST either be a variable, an IRI, or a literal.
These components MUST NOT be blank nodes.
A Triple Pattern Fragment is considered empty if it does not contain any data triples (regardless of metadata and controls).
The above constraints define the Triple Pattern Fragment document type, and are detailed in the following sections , , and . Triple Pattern Fragments SHOULD be paged, as detailed in .
Triple Pattern Fragments are not bound to a specific syntax, since the data, metadata, and controls can be represented in different ways. The server MUST, however, support at least one RDF-based representation. Servers MUST indicate the corresponding MIME type when responding with a Triple Pattern Fragment, so clients can correctly parse it.
For RDF syntaxes without multiple graph support (such as Turtle or N-Triples), the data, metadata, and controls MUST necessarily be serialized to the same graph. For RDF syntaxes with multiple graph support (such as JSON-LD, TriG or N-Quads), the data MUST be serialized to the default graph and the metadata and controls MUST be serialized to one or multiple non-default graphs.
The data of a Triple Pattern Fragment is obtained by selecting all triples of a dataset that match the fragment's triple pattern selector. These triples SHOULD be ordered in some consistent way, such that Triple Pattern Fragments can be paged consistently. Triples SHOULD NOT contain blank nodes (if the original triples contain blank nodes, they SHOULD be skolemized).
If the RDF syntax supports multiple graphs, data triples MUST be serialized to the default graph.
Each Triple Pattern Fragment, and each page of a Triple Pattern Fragment, MUST contain the estimated total number of triples that match the fragment's selector. This MUST be expressed as a triple with the following components:
void:triples
predicateThe estimate MUST be a non-negative, finite, integer number with the following properties:
The metadata MAY additionally contain variations of the above triple.
For instance,
it is RECOMMENDED to add a triple with the same subject and object
and the hydra:totalItems
predicate.
If the RDF syntax supports multiple graphs,
metadata triples MUST be serialized to a non-default graph.
This non-default graph SHOULD be explicitly related to the Triple Pattern Fragment
(for instance, using the foaf:primaryTopic
predicate),
so clients can interpret what resource this metadata belongs to.
This graph MAY be the same as the graph containing the hypermedia controls.
Each Triple Pattern Fragment, and each page of a Triple Pattern Fragment, MUST contain a hypermedia control that can generate the IRI of each other Triple Pattern Fragment of the same dataset.
This control MUST act as a function that accepts three parameters subject, predicate, and object, each of which can either be a variable, a constant IRI, or (in the case of object) a constant literal. It MUST then map these parameters to the IRI of the dataset's Triple Pattern Fragment whose selector has the given parameter values.
This control MUST be expressed as a form in the Hydra Core Vocabulary [[!HYDRA-CORE]] using triples with the following structure:
<http://example.org/example#dataset>
void:subset <http://example.org/example?s=http%3A%2F%2Fexample.org%2Ftopic>;
hydra:search [
hydra:template "http://example.org/example{?s,p,o}";
hydra:mapping [ hydra:variable "s"; hydra:property rdf:subject ],
[ hydra:variable "p"; hydra:property rdf:predicate ],
[ hydra:variable "o"; hydra:property rdf:object ]
].
The above snippet assumes the dataset IRI is
http://example.org/example#dataset
,
the fragment (or fragment page) IRI is
http://example.org/example?s=http%3A%2F%2Fexample.org%2Ftopic
,
and the IRI template [[!RFC6570]] to retrieve Triple Pattern Fragments of the dataset is
http://example.org/example{?s,p,o}
.
It furthermore assumes that the parameter names of
subject, predicate, and object
are s
, p
, and o
, respectively.
All of these MUST be adjusted to fit the configuration of a specific fragments server.
Note that the form MUST be attached to the dataset,
as the form filters the dataset and not the fragment,
and the fragment MUST explicitly be listed as a subset of the dataset,
in order to indicate the relation between the two.
This hypermedia control MUST be present because there purposely does not exist a fixed IRI format that servers of Triple Pattern Fragments need to follow. This means that clients of Triple Pattern Fragments MUST NOT need prior knowledge of a server, i.e., they MUST NOT assume a certain IRI pattern. Instead, clients MUST interpret the hypermedia control in each Triple Pattern Fragment in order to retrieve another fragment. Clients MUST NOT attempt to deconstruct IRIs of fragments, i.e., they MUST treat these as opaque identifiers.
The hypermedia control fulfills the hypermedia constraint
that each representation should contain the controls towards next steps.
As a result, clients can use Triple Pattern Fragments
without any prior knowledge.
This also means a server can freely choose
the IRIs of its Triple Pattern Fragments,
as well as the names of parameters
(e.g., subject
, predicate
, object
instead of s
, p
, o
in the above snippet).
An equivalent hypermedia control for the above snippet could look as follows:
<form method="GET" action="http://example.org/example">
<fieldset>

subject <input id="subject" name="s" />

predicate <input id="predicate" name="p" />

object <input id="object" name="o" />

</fieldset>

<input type="submit" />

</form>
Clients can obtain the IRI of a specific fragment through a hypermedia control in fragments' representations. However, since hypermedia controls generally accept strings as input, we need to specify how to convert IRIs, literals, and variables to strings for use as subject, predicate, and object parameter values. The interface MUST at least support the following options:
http://example.org/bar
"
,
e.g., "my text"
"
followed by @
and the lowercase language code [[!BCP47]]
e.g., "my text"@en-gb
"
followed by ^^
and the text value of the IRI
e.g., "42"^^http://www.w3.org/2001/XMLSchema#integer
?var
.
The Hydra Core Vocabulary captures the above (see issue 30). Maybe it should not be repeated here.
We should talk about support for patterns such as { ?s ?p ?s }
.
If the RDF syntax supports multiple graphs,
control triples MUST be serialized to a non-default graph.
This non-default graph SHOULD be explicitly related to the Triple Pattern Fragment
(for instance, using the foaf:primaryTopic
predicate),
so clients can interpret what resource the controls are related to.
This graph MAY be the same as the graph containing the metadata.
Triple Pattern Fragments SHOULD be paged to avoid overly large responses. A page of a Triple Pattern Fragment consists of the following three parts:
hydra:view
.
void:triples
predicate
that expresses the estimated total number of matches for the fragment's triple pattern.
hydra:previous
.
The previous page SHOULD NOT be empty.
hydra:next
.
The next page SHOULD NOT be empty.
A page is considered empty if it does not contain any data triples (regardless of metadata and controls).
Pages MAY be accessible by page number through an additional hypermedia control. In any case, clients MUST NOT attempt to deconstruct IRIs of pages, i.e., they MUST treat these as opaque identifiers.
A server can make one or more datasets available as Triple Pattern Fragments. For a server to be called a Triple Pattern Fragments server of a given dataset, it MUST offer access to all possible Triple Pattern Fragments of that dataset. Triple Pattern Fragments MAY be accessible through one or more representations, at least one of which MUST be RDF-based [[!RDF11-CONCEPTS]].
Each Triple Pattern Fragment MUST follow the document type defined in and MUST be accessible through a canonical IRI. All representations supported by the server MUST be accessible through this canonical IRI; individual representations SHOULD NOT have their own IRI. Support for representations must be consistent, that is, if a Triple Pattern Fragment is available in a certain representation, then all of the Triple Pattern Fragments MUST be available in that representation.
Triple Pattern Fragments servers MAY additionally offer access to other Linked Data Fragments of the dataset.
As an example, we consider how a Triple Pattern Fragments interface could be implemented on top of the HTTP protocol [[RFC7230]].
A server assigns IRIs to all possible (pages of) Triple Pattern Fragments of its datasets. How IRI assignment happens is implementation-dependent; this choice is communicated to clients through the hypermedia controls of fragments' representations.
A IRI of a fragment identifies the fragment resource, not a representation thereof. All representations are accessible through the fragment's canonical IRI using content negotiation [[RFC7230]]. No specific IRIs are necessary for individual representations.
In order to allow browser applications to access fragments, Cross-Origin Resource Sharing [[CORS]] has to be enabled on the server. To this end, Triple Pattern Fragments servers should emit the following header and value on all HTTP responses to requests for Triple Pattern Fragments, regardless of their status code:
Access-Control-Allow-Origin: *
As this example indicates, a Triple Pattern Fragments interface is fully defined by its document type (). No protocol-level agreements are necessary. In the case of HTTP, these are provided by the HTTP protocol itself.


BTS star RM admits he feels 'pressure' to be 'perfect'
BTS have spoken about the ‘pressure’ they feel to present themselves in a ‘perfect’ way to their fans.
Despite their huge fanbase, called ARMY, being more concerned with the members being happy and healthy, rapper RM admits he feels he has to maintain a certain image.
‘It would be untruthful if I said there was no pressure. Still, on stage I want to do really well,’ he told Paper Magazine.
Suga, also a rapper, agreed with him, saying: ‘I would not be telling the truth if I said there’s no pressure. But what can you do? Pressure is also one part of life.’
J-Hope added: ‘I can’t say we don’t [feel pressure]. These days, I feel like I live with a sense of mission.
‘Rather than thinking, “It has to be perfect!,” I do what I have to do, making sure I remember the really important and fundamental things and trust that the results will follow.’

The seven member K-Pop group, made up of RM, Suga, J-Hope, Jungkook, Jin, Jimin and V, recently took some time away from the spotlight after their mammoth Love Yourself world tour, and the release of their latest album Map Of The Soul: Persona.
The south Korean group have three nominations at the upcoming American Music Awards for tour of the year, favourite social artist and favourite duo or group – pop/rock.
For Tour of the Year, the boys will be up against Ariana Grande, Ed Sheeran, Elton John, and Pink.
Recently vocalist Jin teased BTS’ next comeback during their Love Yourself: Speak Yourself show in Seoul.
After performing the likes of Dionysus and Fake Love, the 26-year-old made the grand announcement.
‘We will hurry and come back with a new album soon. It will be really soon,’ he told the crowd, according to Yonhap.
The star continued: ‘While I performed Epiphany, I was saddened at thinking that this might be the last time I’d sing it. ‘Thinking that “It’s the end”, it was bittersweet.’

This code is a Python package that uses Psi4’s DETCI module to run Fock-space CI (RAS-nSF-IP/EA) calculations. The method handles spin and spatial degeneracies in molecular systems by solving the orbitals of a reference state that can be well-represented by a single determinant, and then using non-particle-conserving and non-spin-conserving operators to obtain the desired state. A more detailed description of the method itself can be found here. Further details about this method, including examples and analysis, can be found in this paper.
Installation¶
Clone the program from the GitHub repository:
$ git clone https://github.com/shannonhouck/psi4_spinflip_wfn.git
Then navigate into the directory and use pip to install:
$ cd psi4_spinflip_wfn
$ pip install -e .
You can import this as a Python package and use it however you want! If you have pytest installed, you can use it to test your installation:
$ cd psi4fockci
$ pytest
Running CAS-nSF-IP/EA¶
The program is primarily run through the sf_cas
function call. The
function should be run as follows:
Initialize a Psi4.core.Molecule object with the correct reference charge/multiplicity.
Determine the target charge/multiplicity.
Run
sf_cas
.
In order to run a 1SF-CAS/STO-3G 2-SF 1-IP calculation on N2+, one could set an input file up as follows:
import psi4
import spinflip
from spinflip import sf_cas
# setting up molecule
n2 = psi4.core.Molecule.create_molecule_from_string("""
0 7
N 0 0 0
N 0 0 2.5
symmetry c1
""")
# set target charge and multiplicity
charge = 1
multiplicity = 2
# set up additional options
options = {"basis": "sto-3g"}
# run SF-CAS
e = sf_cas( charge, multiplicity, n2, conf_space="" , add_opts=options)
This file can subsequently be run from the command line:
$ python example.dat
All relevant information is written to standard output.
Passing Keywords to Psi4¶
Additional keywords can be passed to Psi4 using the add_opts
keyword.
These options should be put in the dictionary form usually taken by Psi4.
For example, if I wanted to change the number of CI roots, I could specify
it as follows:
options = {"basis": "sto-3g", "num_roots": 10}
e = sf_cas( charge, multiplicity, n2, conf_space="" , add_opts=options)
Adding Excitations¶
Excitations are important, particularly for the nSF-IP/EA schemes.
(Hole excitations are recommended for IP-type and particle excitations
are recommended for EA-type; see the paper for details.)
Excitations outside of the CAS space can be requested by setting the
conf_space
keyword appropriately. The following keywords are valid:
""
CAS-nSF-IP/EA (no additional excitations)
"h"
RAS(h)-nSF-IP/EA (hole excitations)
"p"
RAS(p)-nSF-IP/EA (particle excitations)
"S"
RAS(S)-nSF-IP/EA (singles)
"SD"
RAS(SD)-nSF-IP/EA (singles and doubles)
"SDT"
RAS(SDT)-nSF-IP/EA (singles, doubles, and triples)


This is a non-modal way to live with three keyboard layouts. It maps single presses of modifier keys (leaving long presses to being original modifiers) to unconditionally enable some keyboard layout.
See a blog post about switching keyboard layouts why this is good.

In this program, we are using a 3rd order FitzHugh-Nagumo model which follows the governing equations below.
\[ \frac{\partial v}{\partial t} = D\nabla^2v + v(1-v)(v-a)-w \] \[ \frac{\partial w}{\partial t} = \epsilon(bv-w+\delta) \]
where $v$ and $w$ are the state variables, and the rest of the parameters determine the dynamics of the system and are determined through the graphical user interface.
The first canvas shows the colorplot of the $v$ variable over the domain while the next canvas shows the nullclines and the trajectory of a single cell for 600 units of time starting from the click values set through the graphical user interface.
You can click on the nullcline plot to choose the initial conidtion. Using the same initial condition, you can also click on the color plot to purturb the solution and see the effects. Throught the graphical interface, you can choose whether you intend to purturb both $v$ and $w$ variable or just one of them.

Enter lists of HGNC symbols, Entrez IDs, or ENSEMBL gene IDs separated by spaces or line break. If any allow-list gene is given, only variants in a allow-listed gene are shown. Variants in block-listed genes are excluded.
Enter list of regions to restrict to. If empty then variants will be returned genome-wide.


Periodic changes in the tilt of the Earth’s axis alter the distribution of incoming solar radiation. Here, the authors show that the temperature response to this forcing seemingly differs in models and Antarctic ice cores, with a better agreement reached if ice cores are recording a seasonally weighted signal.
