Guarding Zion
It is the 22th century, and machines with supreme artificial intelligence have conquered the world. Humans are kept alive by a computer controlled program, the Matrix, for no other purpose than providing energy to the machines. Only a small group of freedom fighters have escaped the Matrix and built a secret resist base, Zion, near the core of the earth. However the machines have discovered this and send down millions of sentinels to destroy Zion.
The underground world is actually the sewers of the previous cities in ruin — gigantic tunnels connecting the ground, Zion, and various other intersections. However all sewers have been destroyed when the machines first conquered the mankind. Because of limited time, the sewers have been repaired by people from Zion such that there will always be no more than one path from one intersection to another. No tunnel connects an intersection to itself. The best weapon we have is EMP (electromagnetic pulse) charge, an extremely powerful weapon to use against machines. Blowing an EMP charge will cause any electronic device within its range to stop functioning, therefore destroying the machines within range completely. However it can also cause another EMP charge within the range to malfunction, so the distance between any two EMP charges must be no less than their range.
The council has decided to put EMP on certain intersections to minimize the possibility of the machines destroying Zion. Since our resources are limited, we can only afford to put EMP charges on certain intersections of the underground tunnels. Deploying an EMP charge on a certain intersection has a non-negative cost. What is the maximal distance you can cover with EMP charges, and what’s the minimum cost to achieve that maximal distance?
There are multiple test cases in the input file. Each test case starts with three integers N , M and D , (2<=N<=300, 1<=M<=3000) , the number of intersections, the number of edges, and the range of each EMP charge, respectively. Intersections are numbered from 0 to N – 1 . The following line consists of N integers, the cost of deploying an EMP charge on intersection i . The next M lines each consists of three integers S , T , and C , (0<=S, T<=N – 1, 1<=C<=20000) , meaning that intersection S and T are connected by a tunnel whose length is C . Every test case ends with one blank line indicating the end of test case.
N = 0 , M = 0 , D = 0 indicates the end of input file and should not be processed by your system.

Disney takes 'Star Wars' to streaming with 'Mandalorian'
WEST HOLLYWOOD, Calif. (Reuters) - The next adventure in the “Star Wars” movie and TV franchise, arriving Tuesday on Walt Disney Co’s new streaming service, takes place on a lawless planet at the outer reaches of the galaxy.
“The Mandalorian,” an eight-episode live-action series, stars “Game of Thrones” actor Pedro Pascal as a helmeted bounty hunter. It will be available on Disney+, a new $7-per-month online subscription meant to compete with Netflix Inc.
As is typical with “Star Wars,” Disney and the cast have revealed little about the plot.
“Just kind of imagine crossing the borders and going into unknown territory ... with a lot of familiar elements and completely brand new elements,” Pascal said in an interview with Reuters.
“The Mandalorian” is set between the events of “Return of the Jedi” and “The Force Awakens,” the sixth and seventh installments in the “Star Wars” movie saga.
Disney will release the first episode on Tuesday and the second on Friday, followed by one installment each Friday after that.

This is one of my stalwart recipes that used to only make an appearance when there was a vegetarian over at my house. But then the family began to fall in love with the soft wintry flavours and that creamy white sauce.
Preheat the oven to 220C/425F/Gas 7.
Put the kettle on to boil for the vegetables.
Meanwhile, finely grate the parmesan for the topping, toss in a small bowl with the breadcrumbs and set aside.
When the kettle has boiled, tip the prepared sweet potato and butternut squash into a large pan, add a little salt and then pour the boiled water over to cover. Put the lid on, bring back to the boil and then leave to bubble away for 15-20 minutes until tender.
Fill the kettle up with water again and pop it back on to boil while you quickly prepare the herbs for later. Run your fingers down the length of the rosemary stalks to release the leaves and roughly chop them with the sage leaves and set aside in a small bowl.
Pour the boiled water into a large pan, add a drizzle of oil, slip in the lasagne sheets and leave to cook for five minutes. (As there is not loads of liquid in this dish the lasagne sheets do need a bit of precooking).
In the meantime, prepare the sauce. Finely grate the parmesan and peel and grate the ginger. Place both into a medium bowl, add the ricotta, egg yolks, pinch of nutmeg, salt and pepper, stir to combine and set aside.
Drain the lasagne sheets once they’ve had their time and tip them back into the pan. Drizzle in a little more oil and gently toss them about to coat, so that the sheets don’t stick together.
Check that the vegetables are now nice and tender. Drain well and tip them back into the pan. Mash them with a masher until smooth and add salt and pepper to taste.
Now assemble the lasagne in a baking dish, set on a baking tray. Spread a third of the vegetable mash in the base of the dish. Next, scatter a third of the herbs, pine nuts and spinach leaves over. Then arrange four lasagne sheets on top, cutting to fit if necessary. Spread a third of the white sauce over.
Repeat this two more times giving you three layers and finally sprinkle the parmesan breadcrumbs on top. Bake for 15-20 minutes.
Prepare the salad dressing by simply mixing the olive oil, balsamic vinegar, mustard powder (if using) and seasoning together in a small bowl.
When the lasagne is ready, the pasta will feel tender when pierced through with a knife and the top will be crisp and golden-brown.
Cut it into portions, carefully lift out and serve with a handful of rocket drizzled with the dressing.

pips Red=84 White=85
(CorrectAnswer= 0/0, ErrorScore= 0)
This position comes from the Battersea chouette. White had just rolled 61 and had to leave a shot after playing 11/5, 6/5. The box (Black) then pondered for some time but finally doubled all five of the team members.
In what is a very volatile position the double is perfectly correct and not doubling would be a massive blunder. Black has fourteen hitting numbers and when he hits he will be about even money to win a gammon. There ensued a long discussion between the team which lead to the weakest player present dropping because of the gammon threat.
Instead of analysing the position calmly three more of the team acted like lemmings by following the first dropper over the cliff and each handed the box a point. Worse was to follow.
The fifth team member, immune from the lemming principle, analysed calmly and collectively and came to the very reasonable conclusion that position was actually a very comfortable take. In this he was entirely correct. After all, there are 22 numbers where Black doesn't hit, the race is equal and Black has bad numbers of his own as soon as his next turn. The fifth player took.
There is a rule in the chouette that if only one player takes then he must give the other droppers the option of an 'extra'. This means that each player pays the taker an extra point to accept the cube on 2 - the idea being that if the position truly is a drop then those who dropped have a chance to get their money back.
The lemmings compounded their original error by all offering an extra which the fifth play then accepted. He now held five cubes (his own plus the four extras) on two and had already been paid four points.
The box now rolled one of his worst numbers, 63, which he had to play 18/9. The fifth player was beginning to look good value for his takes! He rolled 64, played 13/7*, 11/7, putting Black on the bar. Black came in immediately with a 41, which he played bar/24, 9/5.
How it was White's turn to ponder. Holding five cubes on two he took his time but decided his position was strong enough to redouble, which is precisely what he did. XG has this position as a borderline double or no double and an easy take but our fifth player is no shrinking violet and so the cubes came across on four.
Everybody took and despite Black rolling an early 65 to escape his rear checker he could not catch up in the race and so the lemmings paid a heavy price for dropping the original double. Meanwhile the fifth player calmly banked twenty-four points - five each from the lemmings and four from the Box.
By sticking to his principles and calmly analysing the position the fifth player was handsomely rewarded for his play. Meanwhile, the lemmings each lost six points - don't forget they had already given the box one point each before erroneously embarking on the extras. An expensive lesson indeed.

JSON Schema is a JSON media type for defining the structure of JSON data. JSON Schema provides a contract for what JSON data is required for a given application and how to interact with it. JSON Schema is intended to define validation, documentation, hyperlink navigation, and interaction control of JSON data.
This specification defines JSON Schema core terminology and mechanisms; related specifications build upon this specification and define different applications of JSON Schema.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
The terms "JSON", "JSON text", "JSON value", "member", "element", "object", "array", "number", "string", "boolean", "true", "false", and "null" in this document are to be interpreted as defined in RFC 4627 [RFC4627].
When refering to a JSON Object, as defined by [RFC4627], the terms "member" and "property" may be used interchangeably.
When refering to a JSON Array, as defined by [RFC4627], the terms "element" and "item" may be used interchangeably.
A JSON Schema is a JSON document, and that document MUST be an object. Object members (or properties) defined by JSON Schema (this specification, or related specifications) are called keywords, or schema keywords.
A JSON Schema MAY contain properties which are not schema keywords.
An empty schema is a JSON Schema with no properties, or with properties which are not schema keywords.
This example of a JSON Schema has no subschemas:
{ "title": "root" }
JSON Schemas can also be nested, as in this example:
{ "title": "root", "otherSchema": { "title": "nested", "anotherSchema": { "title": "alsoNested" } } }
In this example, "nested" and "alsoNested" are subschemas, and "root" is a root schema.
JSON Schema defines seven primitive types for JSON values:
Two JSON values are said to be equal if and only if:
An instance is any JSON value. An instance may be described by one or more schemas.
An instance may also be referred to as "JSON instance", or "JSON data".
This document proposes a new media type "application/schema+json" to identify JSON Schema for describing JSON data. JSON Schemas are themselves written in JSON. This, and related specifications, define keywords allowing to describe this data in terms of allowable values, textual descriptions and interpreting relations with other resources. The following sections are a summary of features defined by related specifications.
JSON Schema allows applications to validate instances, either non interactively or interactively. For instance, an application may collect JSON data and check that this data matches a given set of constraints; another application may use a JSON Schema to build an interactive interface in order to collect user input according to constraints described by JSON Schema.
JSON Schema provides a method for extracting link relations from instances to other resources, as well as describing interpretations of instances as multimedia data. This allows JSON data to be interpreted as rich hypermedia documents, placed in the context of a larger set of related resources.
It is acknowledged that an instance may be any valid JSON value as defined by [RFC4627]. As such, JSON Schema does not mandate that an instance be of a particular type: JSON Schema can describe any JSON value, including null.
JSON Schema is programming language agnostic. The only limitations are the ones expressed by [RFC4627] and those of the host programming language.
This specification acknowledges the role of HTTP [RFC2616] as the dominant protocol in use on the Internet, and the wealth of official specifications related to it.
This specification uses a subset of these specifications to recommend a set of mechanisms, usable by this protocol, to associate JSON instances to one or more schemas.
JSON Schema does not define any semantics for the client-server interface for any other protocols than HTTP. These semantics are application dependent, or subject to agreement between the parties involved in the use of JSON Schema for their own needs.
It is acknowledged by this specification that some programming languages, and their associated parsers, use different internal representations for floating point numbers and integers, while others do not.
As a consequence, for interoperability reasons, JSON values used in the context of JSON Schema, whether that JSON be a JSON Schema or an instance, SHOULD ensure that mathematical integers be represented as integers as defined by this specification.
Implementations MAY choose to define additional keywords to JSON Schema. Save for explicit agreement, schema authors SHALL NOT expect these additional keywords to be supported by peer implementations. Implementations SHOULD ignore keywords they do not support.
Both schemas and instances are JSON values. As such, all security considerations defined in RFC 4627 [RFC4627] apply.
The "$schema" keyword is both used as a JSON Schema version identifier and the location of a resource which is itself a JSON Schema, which describes any schema written for this particular version.
This keyword MUST be located at the root of a JSON Schema. The value of this keyword MUST be a URI [RFC3986] and a valid JSON Reference [json-reference]; this URI MUST be both absolute and normalized. The resource located at this URI MUST successfully describe itself. It is RECOMMENDED that schema authors include this keyword in their schemas.
The following values are predefined:
When extending JSON Schema with custom keywords, schema authors SHOULD define a custom URI for "$schema". This custom URI MUST NOT be one of the predefined values.
JSON Schema uses JSON Reference [json-reference] as a mechanism for schema addressing. It extends this specification in two ways:
Altering the URI within a schema is called defining a new resolution scope. The initial resolution scope of a schema is the URI of the schema itself, if any, or the empty URI if the schema was not loaded from a URI.
 This URI MUST be normalized, and SHOULD NOT be an empty fragment (#) or the empty URI.
The "id" keyword (or "id", for short) is used to alter the resolution scope. When an id is encountered, an implementation MUST resolve this id against the most immediate parent scope. The resolved URI will be the new resolution scope for this subschema and all its children, until another id is encountered.
When using "id" to alter resolution scopes, schema authors SHOULD ensure that resolution scopes are unique within the schema.
This schema will be taken as an example:
{ "id": "http://x.y.z/rootschema.json#", "schema1": { "id": "#foo" }, "schema2": { "id": "otherschema.json", "nested": { "id": "#bar" }, "alsonested": { "id": "t/inner.json#a" } }, "schema3": { "id": "some://where.else/completely#" } }
Subschemas at the following URI-encoded JSON Pointer [json-pointer]s (starting from the root schema) define the following resolution scopes:
When resolving a URI against a resolution scope, an implementation may choose two modes of operation:
Implementations MUST support canonical dereferencing, and MAY support inline dereferencing.
For example, consider this schema:
{ "id": "http://my.site/myschema#", "definitions": { "schema1": { "id": "schema1", "type": "integer" }, "schema2", { "type": "array", "items": { "$ref": "schema1" } } } }
When an implementation encounters the "schema1" reference, it resolves it against the most immediate parent scope, leading to URI "http://my.site/schema1#". The way to process this URI will differ according to the chosen dereferencing mode:
When using inline dereferencing, a resolution scope may lead to a URI which has a non empty fragment part which is not a JSON Pointer, as in this example:
{ "id": "http://some.site/schema#", "not": { "$ref": "#inner" }, "definitions": { "schema1": { "id": "#inner", "type": "boolean" } } }
An implementation choosing to support inline dereferencing SHOULD be able to use this kind of reference. Implementations choosing to use canonical dereferencing, however, are not required to support it.
Inline dereferencing can produce canonical URIs which differ from the canonical URI of the root schema. Schema authors SHOULD ensure that implementations using canonical dereferencing obtain the same content as implementations using inline dereferencing.
Extended JSON References using fragments which are not JSON Pointers are not dereferenceable by implementations choosing not to support inline dereferencing. This kind of reference is defined for backwards compatibility, and SHOULD NOT be used in new schemas.
It is acknowledged by this specification that the majority of interactive JSON Schema processing will be over HTTP. This section therefore gives recommendations for materializing an instance/schema correlation using mechanisms currently available for this protocol. An instance is said to be described by one (or more) schema(s).
It is RECOMMENDED that a MIME type parameter by the name of "profile" be appended to the "Content-Type" header of the instance being processed. If present, the value of this parameter MUST be a valid URI, and this URI SHOULD resolve to a valid JSON Schema. The MIME type MUST be "application/json", or any other subtype.
An example of such a header would be:
Content-Type: application/my-media-type+json; profile=http://example.com/my-hyper-schema#
When using the "Link" header, the relation type used MUST be "describedBy", as defined by RFC 5988, section 5.3 [RFC5988]. The target URI of the "Link" header MUST be a valid JSON Schema.
An example of such a header would be:
Link: <http://example.com/my-hyper-schema#>; rel="describedBy"

Abstract: We initiate the study of learning from multiple sources of limited data, each of which may be corrupted at a different rate. We develop a complete theory of which data sources should be used for two fundamental problems: estimating the bias of a coin, and learning a classiﬁer in the presence of label noise. In both cases, efﬁcient algorithms are provided for computing the optimal subset of data. 1

Last week, the party continued interrogating1 Kaler, the leader of the hobgoblins they defeated. He told them that a group of hobgoblin scouts would arrive in two hours, and that he could question them on behalf of the party. They agreed, and when the scouting party arrived, Kaler told them not to approach the town and asked what they had found. The scouts said that Torvid, the bandit chief, had sent a larger force to take the town than expected. Unusually, the force featured three ankhegs - huge insect-like creatures known for their digging abilities and ambush tactics, dragging their foes down into the depths and eating them. In addition, the force was arriving ahead of schedule, and would arrive at the town in just two hours.
After this revelation, the scouting party insisted on knowing what was going on with Kaler, and whether they should attack the town. Balrox took the lead by summoning a cloud of fiendish darkness at the entrance and walking boldly out to face the hobgoblins. He was soon backed up other members from the party2, and the hobgoblins decided that attacking was not their best option. With the conflict averted and the information acquired, the party bid Kaler farewell. He indicated they would be on friendly terms if they met again.
The party then decided to focus on fortifying the town to prepare for the assault. They mapped out the town's structure and cobbled together a series of gangplanks connecting many of the rooftops, allowing them to avoid attacks from the ankegs. A search of the town revealed three kegs of alcohol which could serve as impromptu explosives3. Attempts were also made to construct a number of creative traps from various household items4.
Before long, however, the enemy forces arrived outside of town: five hobgoblin warriors, three hobgoblin clerics, ten kobolds, and three ankhegs. The party took cover on the rooftops to observe. Seeing the town empty, the hobgoblins were suspicious and sent in the kobolds first. As soon as the kobolds entered the town, they promptly exploded5.
The hobgoblins took a somewhat more cautious approach after the fiery demise of half of their forces. They released the krakens ankhegs, who all burrowed underground to parts unknown, and fashioned a ten-foot pole from the town wall to probe the ground for more kegs. As the party watched quietly, they found another explosive trap at the entrance from a safe distance, and were able to avoid it. Meanwhile, Amanita sensed one of the ankhegs burrowing towards the final keg. When the ankheg grabbed the keg, Balrox shot another flaming arrow, causing the keg to explode in the creature's mouth.
This explosion provoked the hobgoblins to charge into the town, and things became chaotic. The nearly incinerated ankheg retreated underground, never to be seen again, but his place was soon filled by the remaining monsters. The hobgoblin warriors charged into the building the party occupied, trying to reach one of the roofs, while the clerics remained on the ground and blasted the party with magic. Barbie and Maxwell jumped off of a roof and charged into combat with one of the ankhegs on the ground floor of the building. Traps impeded the warriors' progress to the roof, but they still made quick time and were soon engaged in melee with Pabst, Lorelai, and Amanita. Meanwhile, Balrox, Elodie, and Crumbum snuck towards the clerics to attack them - but retreated when an ankheg came out of the ground to support the clerics.
On the main roof, the hobgoblin warriors fared poorly against Pabst's axe and Lorelai's tendency to get hit repeatedly by attacks. However, Barbie was grabbed by an ankheg and dragged underground. Amanita jumped off the roof to rush to her aid, and together they killed the ankheg. Balrox, Elodie, and Crumbum held their own against the clerics and ankheg long enough for the party to wipe out most of the opposition and provoke three surviving hobgoblins into surrendering. Before the party could join together to annihilate the remaining ankheg, it burrowed away, ending the fight. Two of the hobgoblin prisoners died fairly quickly6, leaving just one alive to interrogate.
Join us this week to light the signal fire in town and declare victory!

ORM stands for Object Relational Mapping, a technique for converting data between two systems. In our context, we are converting tables in an RDBMS(SQLite) to classes in Ruby. The image above gives a concise representation of what we learned, but here's the rundown for people who like to read.
Active Record is one example of ORM. In our context, it manages the back-end of our application and links the database tables to models.
We were able to have a coach come in the afternoon to talk about an Active Record workflow as we design the back-end of an application. This is what she said.
Where your Models, Views, and Controllers go.
Filenames should be singular lowercase.
Where your data and migrate files are located. Migrate allows you to update and change your database tables and schema with db:migrate while data stores csv files that contain the actual user data.
Filename of migration files are snakecase lowercase. Class names in migration files are camelcase capitalized
Where your rspecs are found.
Where all the gems that are required for the application are stored. When you run bundle, the gems in this file are all installed locally so that you can use the application.
A series of commands that you have created that work upon your entire application directory.
Makes the database file.
Makes the table and schema according to your migrate files.
Rolls back the database to the previous migration file if you do not specify a num.
Drops your tables.


Reflections over Foundations Sprints
Empathetic, Self-Awareness Values
Life's journey, has given me the opportunity to be able to evaluate myself by soulfully checking in, asking: "Am I ok?"" If yes, then keep doing what you love, otherwise if not, what's stopping you from following your dreams & how can you get over this particular hurdle? Life's too short; enjoy it while you can!
We are unique individuals that have to get along with loved ones as well as your peers or colleagues. So how can a shift in your attitude make things better?
Being a social-butterfly, I enjoy being around other people. Upon reflection, I discovered I 'people-watch'! Just love watching how we interact with others. Humans are such fascinating creatures! I can easily socialise with others, being present in a conversation & being mindful of other people's thoughts & feelings around me. Can't explain how & when this happened, but I've always been able to gauge a person's character from both their spoken language while also observing their body language (that can say something else) as well. Then there's other times where I just need some time out alone to gather my thoughts to re-center & have a chance to heal.
This lead me to understand the difference between Growth vs Fixed Mindsets & EQ vs IQ. I definitely need to expand my mind, constantly searching to fill it with more knowledge; just love being a sponge! 'm more in tune with my Emotional Quotient (EQ) self but I toggle into my intellectual (IQ) self often too. Found it weird that EDA really focused on these areas, but understand where they're coming from & why they're wanting us to develop an understanding here. I did find the core learning challenging in the sense that I came into this training already having an understanding about this & I would have preferred us to have the option to opt out so that I could spend more time focusing on the programming aspects instead. But in saying that, found 'neuroplasticity' quite interesting in the end.
Having an entreuprenual vibe, I already knew that I do things differently to the normal. My visions tend to be quite extreme where people can't see the end-goal until it's right there in front of them. I'm one of those people at the moment where I kow where I want to be but can't see how to get there. But I'm a go-getter, where I'll set myself a target to achieve & will somehow find a way to reach this goal.
Since starting this course, I've had the fingers crossed that things will all make sense somehow. It's the drive that's kept me here having a sense of upskill yourself & utilise your smarts to do something you're passionate about.
My ego is usually in check & never really explodes too large, unless I'm in a comfortable environment & my singing takes centre-stage. In relation to learning & programming, my ego needs to take a back-seat as I need to reach out more to either my facilitators, or our Slack Community as soon as I get stuck just to help me cross the line with a better understanding of things.
Bootcamp Expectations
Long Term Goal & Career Path
Confidently being able to hold my ground as a well rounded programmer, being able to work together as a team & to also be able to take this skillset anywhere around the world & work hours that are suitably adjustable for my other interests in my realm.
Biggest Strengths & Limitations
Compared my thoughts from Sprint 2 to now; still the same. I have numerous interests that I would love to surround myself with daily. I seem to be able to multi-task a little better now that I have a few more weeks settled in however, silence is still my 'go-to' throughout the day & noticed my brick wall ego still exists. It's weird as I am literally scared of programming, yet it is something that I am drawn to still; how does that work?! Must be that 'Growth Mindset' going on!
Biggest Non-Technical Challenge
Not being physically together in the same location as my cohort
Non-Techncial Skills - Human Skills
Teaming up with the Peer Programming. Hoping this adjustment will be beneficial for myself as well as my peers
Bootcamp Expectations
Wanting to be able to put my hand up in a timely manner in order to be able to keep up with the rest of the cohort. I'm wanting to have the opportunity to learn & grow with confidence in programming
