--------------
**zeroth**: /zee´rohth/, adj.
First. Among software designers, comes from C's and LISP's 0-based
indexing of arrays. Hardware people also tend to start counting at 0
instead of 1; this is natural since, e.g., the 256 states of 8 bits
correspond to the binary numbers 0, 1, ..., 255 and the digital devices
known as counters count in this way.
Hackers and computer scientists often like to call the first chapter of
a publication ‘Chapter 0’, especially if it is of an introductory nature
(one of the classic instances was in the First Edition of
`*K&R* <../K/K-ampersand-R.html>`__). In recent years this trait has
also been observed among many pure mathematicians (who have an
independent tradition of numbering from 0). Zero-based numbering tends
to reduce `*fencepost error* <../F/fencepost-error.html>`__\ s, though
it cannot eliminate them entirely.

Composting is the process of decaying organic material used as a plant fertilizer to create fresh soil. Composting is an essential element in the circle of life.
Read MoreComposting is an important factor for the enviornment as a whole. The main reason why we should simply start composting is add to the creation of new, nutrient rich soil. When composting, the worms located in the soil decompose the various foods and turn it into fresh soil. This soil cana be used to plat more crops, and make the enviornment a stable and healthy place.
Click below to see what the composted soil can be used forComposting can occur anywhere, anyday, and any place. Let us all commit to raise awareness about the benefits of composting. By doing so in schools, resturants, and at home, we can improve ur enviornment, one step at a time.
Start a petition to bring back composting TODAY!

--- layout: presentation title: Subgraph Matching (ATC) order: 9 --- ## Subgraph Matching **Jacob Moorman** -vertical- In collaboration with *Thomas Tu, Qinyi Chen, Xie He, and Andrea Bertozzi* of UCLA Department of Mathematics -vertical- Work funded by DARPA under the Modeling Adversarial Activity (MAA) program -vertical- Jacob was funded by NSF grant DGE-1829071 -vertical- Slides are online at [bit.ly/jacobsm](http://bit.ly/jacobsm) Code is on GitHub at [bit.ly/ucla-sm](http://bit.ly/ucla-sm) -horizontal- ## Subgraph Matching Find all copies of a **template** network in a **world** network An instance of the *template* in the *world* is called a **signal** -vertical- ## Backstory 1. DARPA hired several teams (PNNL, IvySys, GORDIAN) to generate synthetic networks 2. DARPA challenged other teams to create algorithms to solve subgraph matching on those networks 3. We succeeded. -vertical- ## An easier problem | Template Node | Signal Nodes | |:---:|:---:| | A | 1, 4, 7 | | B | 2, 5, 8, 9 | | C | 6, 7, 10 | -horizontal- ## Classic Algorithm: ## Tree Search [Ullmann76, CFSV04] -vertical- 1. Find all signals where \\(\mathbf{A} = \mathbf{1}\\) 1. Find all signals where \\(\mathbf{A} = \mathbf{1}\\) and \\(\mathbf{C} = \mathbf{6}\\) 1. ... 2. Find all signals where \\(\mathbf{A} = \mathbf{4}\\) 3. ... -vertical- ## Tree Search Considerations * **Search Order:** In what order should we match the template nodes? * **Filtering Rules:** To which world nodes should we try matching them? -horizontal- ## Search Order > *In what order should we match the template nodes?* Use a heuristic to precompute a fixed order on the template nodes. -vertical- ## Search Order Objective The objective of the heuristic is to minimize the computational cost of traversing the search tree. -vertical- ## Search Order Heuristics * Fewest candidates first * Most neighbors first * Highest degree first * ... -horizontal- ## Filtering Rules > To which world nodes should we try matching the template nodes? Try matching each template node to world nodes which satisfy some set of constraints. Refer to these world nodes as **candidates**. -vertical- ## Filtering Rules: Node Stats A candidate should have as many incoming/outgoing edges as its corresponding template node. -vertical- | Template Node | Candidates After Stats| |:---:|:---:| | A | 1, 3, 4 | | B | 1, 2, 3, 4 | | C | 4 | -vertical- ## Filtering Rules: Topology Candidates for neighboring template nodes should neighbor other candidates for the corresponding template nodes. -vertical- | Template Node | Candidates Before Topology | Candidates After Topology | |:---:|:---:|:---:| | A | 1, 3, 4 | 1 | | B | 1, 2, 3, 4 | 1, 2 | | C | 4 | 4 | -vertical- ## Filtering Rules: Pigeonhole If **k** world nodes are candidates for the same **k** template nodes, they cannot be candidates for any others. -vertical- | Template Node | Candidates Before Pigeonhole | Candidates After Pigeonhole | |:---:|:---:|:---:| | A | 1 | 1 | | B | 1, 2 | 2 | | C | 4 | 4 | -vertical- ## Filtering Rules: Neighborhood [Solnon09] The neighborhood of a candidate should be matchable to the neighborhood of the corresponding template node. -horizontal- ## Results Filtering rules alone uniquely identify many nodes! -vertical- Expensive filtering rules are not always worth the effort! -vertical- Using a tree search, we are usually able to verify exactly which candidates belong to at least one signal. We are not always able to enumerate all of the signals. -vertical- The filters nearly eliminate all non-signal matchings! -horizontal- ## Future Work * Approximate matching in the presence of noise * Missing nodes/edges * Incorrect attribute info * Attributes beyond node/edge labels (eg. timestamps) -vertical- Attributes can be useful if you are looking for particular signal nodes. -vertical- ## References


Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight. There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma.
We are SCNND (pronounce as scanned). We provide skin cancer detection with the use of convolutional neural network!

I am addicted to learning. I obtained my Associate of Arts Degree by the time I graduated high school, and that was only the beginning. After that I went on to study several languages and graduated from Western Washington University with my Bachelors in Japanese. After teaching in Japan, I completed and intensive program in New York, NY. and received SIT TESOL certification. Three years later I returned to school to get an Associate of Science degree and a license to practice dental hygiene. Now, I'm enrolled at Epicodus, a programming bootcamp in Portland, OR. I began learning to code at first as a hobby, a way to unwind after work as well as a way to bring some much needed creativity back into my life. When I was still coding several years later, I decided to make it my career. I have worn many hats, which means that I can solve problems from many different angles and I bring a lot of different skills to the table!
Dental Hygiene: From 2016 to 2020 I have been working as a dental hygienist in Portland, OR. and currently have an active dental hygiene license.
Administration: I helped onboard incoming students at Kaplan International in downtown Portland. I would also write letters of recommendation, help students apply for renewal of funds from their governments, scan many documents and coordinate and lead student activities.
TESOL Instructor: I instructed students from all over the world who had come to Kaplan International to learn English as their second language.
TESOL Instructor: Working in Izumo, Japan as an English instructor was one of the most incredible experiences I have had in my life. I lived there for a little over a year and worked for AEON.
Here's a picture of Gemma, just for you.

I have done Foxy orally before but don't like the stomach aspects of it, namely the nausea, cramps and general discomfort. So i decided that i should try smoking it.
The setting was perfect, a calm, misty saturday night, i was feeling good and relaxed, put some Allman brothers in the background and got on with the plan. I smoked Foxy the same way I had done DMT in the past, by putting around 25mg of it in the tip of a cigarette (filter removed) and firing it up. Althoug it didnt produce the same kind of 'dissolution of reality' that DMT does, the effect was immediate. I was sitting on a couch and after the second or third puff i couldn't hold the makeshift cigarette anymore. But i had prepared and had an ashtray and a coffe table at hand so no harm was done.
The first wave was overpowering like a sledgehammer slowly compressing my being, a fairly-sized body load. Within a few seconds i started feeling nausea but not too much, and my perception was clearly different, even though a gigantic, inexplicable fear developed. But 5 minutes afterwards I felt no nausea and no fear.
I then stood up (something imposssible earlier) and opened the window to admire the night skies but a thick mist had covered the streets. But I started to notice a strange glow on the mist, like if was about to reveal some inner meaning. It never did, but the effect was quite beautiful. There were absolutely no visuals to speak of, only a heightened sensitivity to colors and shades.
T+15 minutes and I grabbed my acoustic guitar and started playing it. I was amazed by how easy and fluid my playing was, how much i seemed to get 'into' the notes, effortlessly jamming along with the Brothers. This was the most interesting aspect of the trip, the fact that some inner force was guiding my hands and I felt i could play anything, do anything. The Fear and the nausea had long gone and i was supremely detached, immersed in the music. One hour and a half later, i was back to baseline.
All in all, a mild, nice, peaceful trip. I strongly advise this way of ingesting this drug, especially for those who dont deal well with stomach issues.

SoftBank-backed Paytm raises $1 billion in fresh funding
by ReutersNEW DELHI/BENGALURU (Reuters) - Indian digital payments company Paytm said on Monday it has raised fresh funds from a group of investors including existing backers SoftBank's (T:9984) Vision Fund and China's Ant Financial Services in a deal valuing the firm at $16 billion.
Paytm did not officially disclose details of the funding, but a source said the Indian company raised $1 billion in the latest round.
SoftBank's fresh investment in Paytm comes as the Japanese investment firm's founder Masayoshi Son battles to restore his reputation after an ill-fated investment in office-sharing firm WeWork.
New investment deals by SoftBank are also under growing scrutiny after the group reported its first quarterly loss in 14 years, dragged down by an $8.9 billion hit at Vision Fund.
Paytm said on Monday it will expand into insurance, lending, stockbroking and investments and invest 100 billion rupees ($1.4 billion) over the next three years to bring in more users to its services.
"This new investment by our current and new investors is a reaffirmation of our commitment to serve Indians with new-age financial services," Paytm founder and chief executive Vijay Shekhar Sharma said in the statement.
Other investors include Discovery Capital and funds advised by T. Rowe Price Associates.

How might we track interactions and engagement in a virtual environment?
How might we record and visualize this data in VR or on a 2D screen?
How could we apply storytelling methodologies in VR to show data?
In the Accenture Tech Labs, I was tasked with the challenge to develop a foundation for analytics and data visualization in virtual reality, ‘VR’. The purpose was to be able to track and analyze a user’s behavior while in a VR headset. What does a user focus on? Where do they get “stuck”?
With these data insights, we could improve user experience and demos while in a headset. For clients, we could also apply VR data analytics to improve VR training scenarios!
For this project, I worked in the CPG (Consumer Packaged Goods) industry to better understand how users would move and interact with a virtual store.
I was able to create a total of 5 unique data visualization MVPs, and a C-suite client facing demo that I presented in the labs on a weekly basis! Functionality included showing user movement through “trails” in mid-air or on the ground, the ability to show “gaze” or where the user is looking in the store and highlight products based on gaze time length on that object. I also experimented with adding hidden audio “insights” or hotspots into the scene to relay important information to the user, or direct them around the scene in a more “guided” experience.
Overall, I learned a lot from the VR analytics project, and it successfully delivered a working prototype for the Lab and Accenture clients. However, a lot more creativity could have been injected into the process from the beginning. For example, during our brainstorming session, we centered around inspiration from 2D data visualization (d3, graphs, tables, etc.) If forced to think outside of the box (3D pun intended), we could have created even more of a range of 3D data visualization prototypes. I got a hint of this creativity given the unique medium through the audio VR guide experiment, but even more exploration would have been great!

Express D
as a fraction. Reduce to lowest terms.
D
D
can be represented as follows.
= 0 + fraction( D.substr( 2, 1 ) , 10 ) + fraction( D.substr( 3, 1 ) , 100 ) + fraction( D.substr( 4, 1 ), 1000 ) + fraction( D.substr( 5, 1 ), 10000 )
= fraction( NUMERATOR, 10000 )
You can also skip a few steps by making a fraction with NUMERATOR
as the numerator and 10000
(because the decimal extends to the ten thousandths place) as the denominator.
fraction( NUMERATOR, 10000 )
Then, reduce the fractional part by dividing the numerator and denominator by GCD
.
=fractionReduce( round( D * 10000 ) , 10000 )
Express FIXED
as a mixed number. Reduce to lowest terms.
W + D
FIXED
can be represented as follows:
= W + fraction( floor( D * 10 ), 10 ) + fraction( floor( ( D * 100 ) % 10 ), 100 )
= W + fraction( roundTo( 0, D * 100 ), 100 )
Reduce the fractional part by dividing the numerator and denominator by GCD
.
=W + fractionReduce( round( D * 100 ) , 100 )

"Vanilla" Beans and "Dynamically generated subclass"
// this is a "Vanilla" Bean
Order orderVanilla = new Order();
// orderRef is a "Dynamically generated subclass"
Order orderRef = (Order)Ebean.getReference(Order.class, 23);
// It implements the EntityBean interface
EntityBean orderEb = (EntityBean)orderRef;
I have not used the term POJO as I believe some people may well consider orderRef a POJO.
In the documentation I am going to refer to plain ordinary beans as "Vanilla" as compared
with orderRef (in the example above) which is best described as a "Dynamically generated subclass".
Note: As the "Dynamically generated subclasses" implement the EntityBean interface they are often
refered to in the source code as EntityBean's.
Method Interception for Lazy Loading
One of the core demands for using byte code generation is to use method interception
to provide lazy loading for reference/proxy beans.
 The getter method is
intercepted and the lazy loading of the bean is invoked.
The lazy loading will fetch the data for the bean and copy in the non-transient property
values into the bean before returning the customer object.
Method Interception for Optimistic Concurrency Checking
The other core demand of method interception of beans in Ebean is to detect when a
bean is being modified and keep its "Old/Original Values". The "Old Values" is
used to perform Optimistic Concurrency checking
for Beans that do not have a Version property.
There is a code example which can perhaps explain the
creation of "Old Values" and setter interception.
equals and hashcode
In addition a equals and hashcode implementation can be generated and the issues
surrounding this is discussed here.
Reflection Replacement
Another use of Byte code generation is to generate code to replace standard reflection.
Obviously getter and setter methods are used a lot in ORM and ASM is used to generate
code to replace the use of Reflection for performance reasons.

They say that the best way to inspire others is to model it and I have to agree. Modeling something is like magic; while people may be amazed or wonder how you do it, they will attempt (although sometimes only in their minds) to imitate. (Yes, I know Penn & Teller do a great job of explaining magic to us…so let’s not breakdown my analogy too far).
There is someone I know who is an amazingly good at his job. He probably puts in more hours than anyone else I know and he does it because he sincerely loves what he does. And it is infectious; everyone around gets caught up in the passion for the work and strive to do better. It’s a virtuous cycle of benefit to the entire group and he does it out of honest joy. Now imagine if he were to point the fact that he works so many hours. What do you think everyone would assume about his motivation to work so hard? Sure some may miss that detail or even chalk it up to him being informative but for some, it will plant that seed of doubt. That question of, “Does he do this just so he can hold himself up for doing it?”
When you live out a behavior, you inspire those around you. But when you speak of it, even if only to inform and truly not to brag, you lessen the effect of that example.

Google Earth Enterprise Documentation Home | GEE Server administration
Publish databases with search
Google Earth Enterprise (GEE) provides several different ways that you can incorporate search into your published databases, depending on the complexity of the search you want to perform and the data you are searching.
Search functionality is enabled when you publish a database in GEE Server. Different search options are available:
- Turn on POI Search based on search fields you add to a vector resource in a vector project or map layer
- Add default search tabs, enabling queries of local or non-local search data based on Places, Coordinate, POI, and GeocodingFederated searches
- Add custom search tabs, created by custom search plug-ins that incorporate more complex queries and data, such as search results based on geometries.
Add POI Search
If you have one or more text fields that you would like to query from vector resources in a project, you can simply add those search fields to a vector project in a 3D database; for 2D maps, you include a map layer in a map project. Once you’ve added your POI vector project or map layer to the database you want to publish, you push it to GEE Server, then turn on POI Search when you publish.
For example, you may be interested in displaying the US Census Bureau population statistics on your map or globe, based on county name. You can easily add the search fields to the individual population data layer in your vector project. You can also choose how you want the labels for your search results to appear on your globe, such as search and display a field, or simply display it.
You can also modify the appearance of the POI search tab in Google Earth EC by editing the system search tab, POI Search, which sets the query parameters for the search fields you added to your vector layer, as well as specifying the labels for the tab, query field and suggestion box.
Use GEE-provided Search Data
Google Earth Enterprise provides two searchable databases, Places and ExampleSearch, firstly as data that you can add to your globes and maps and secondly as examples that demonstrate the search plug-in functionality of GEE Server.
The Places database in /opt/google/share/geplaces
, provides a searchable database of countries and cities that you can connect to using the POI, GeocodingFederated, Places or Coordinate plug-ins. The Places database is a subset of the publicly available geonames database.
You might use the Places search tab to perform queries based on city names, for example. You might use the Coordinate search tab to perform queries based on city, country, or lat/long values.
The ExampleSearch database in /opt/google/share/searchexample
is a table of San Francisco neighborhoods. The ExampleSearch search tab is provided as a showcase of how a custom search plug-in can be coded to extract geometries from a spatial database and then return the results so that they display according to the query parameters. The plug-in supports query parameters that set flyToFirstElement and displayKeys.
Places and ExampleSearch are both PostgreSQL databases so you can also access them using the psql
command. See PostgreSQL 9.3.5 Documentation.
You can examine the Python code of the search plug-ins on which the search tabs are built, using it as a template for your own plug-in development. To customize your own search plug-ins, see Add custom search services.
About system search tabs
System search tabs are provided with GEE Server. They provide hard-coded queries for various search data types available in the Places database provided with GEE. You can use them to access this database, a subset of the publicly available geonames database or you can edit them for your own purposes. The search tabs cannot be deleted but can be edited and saved with a different name.
The following default search tabs are available:
- POISearch: Search for POIs.
- GeocodingFederated: Search for places or coordinates.
- Places: Search for places using the built-in locations database.
- Coordinate: Search for latitude, longitude pairs. The following formats are supported:
- Decimal Degrees (e.g. 39.507618° -84.168556°)
- Degrees, Minutes, Seconds (e.g. 20°40'01.51" S 131°53'51.39" E)
- Degrees, Decimal Minutes (e.g. 49° 32.876' N 110° 9.193' E)
- Universal Transverse Mercator (e.g. 43 R 637072.95 m E 2825582.86 m N)
- Military Grid Reference System (e.g. 36NTL8040632621)
- ExampleSearch: Search the example table of San Francisco neighborhoods to demonstrate the search plugin functionality.
About search tabs definitions
Search data is accessed via a query interface in Google Earth EC or a browser in the form of search tabs. A search tab definition, which you specify in GEE Server, includes the label you want to apply to the search tab that your users will see, the URL that points to a local or non-local searchable database, supported query parameters, and fields that you specify for your search queries. You can customize the labels and fields in a search tab and use query parameter settings to control how the results of a query will be displayed.
The database to which you point your search tab definition is identified in the query parameters when the globe or map is served. The search tab identifies the database by including the database ID as a parameter in the query string, an internal structure that points to either a searchable database on GEE Server or an external server.
Example query string when serving a local database:
mydb/POISearch?db_id=5&flyToFirstElement;=true&displayKeys;=location&q;=San Francisco
Example query string when serving an external database:
http://mysearch_host.com/search_serviceA?db_id=5&flyToFirstElement;=true&displayKeys;=location&q;=San Francisco
Create custom searches
If you want to access a custom data source, you can create your own search plug-in and access it as a search tab definition in Google Earth Enterprise Server. A custom search plug-in will create requests and responses using the common Python-based search framework, letting you adapt your search to any data source. Your custom search plug-in will receive search requests directly from Google Earth Enterprise Client (EC), or any other clients in the form of URL parameters.
For example, with custom search plug-ins you can use Maps API and Places API to leverage the power of their data sets. You can also use a proprietary database, for example, power conversion sites, then search for the sites using internal IDs or city names.
Summary table of search options
| Search options | Steps summary | Search appearance in Google Earth EC or in a browser |
|---|---|---|
| Query vector data layer using a simple text-based search. | Add a search field to a vector resource in a vector project or map layer. Turn on POI Search in the Publish dialog when you publish your database in GEE Server.
|
The POI Search appears in the main Search tab, labeled Point of interest, including the field label you specified in the vector data layer. |
| Query external database using a default search plugin, for example POI Search. | Edit the POI Search tab URL field to point to your own search database and edit or add query parameters. Add the POI Search tab in the Publish dialog.
|
When you click Query, the POI Search appears as a new additional tab in Search, displaying the custom label and any query field label and suggestion you added. |
| Query the Places database provided by GEE. | Add the Places search tab in the Publish dialog to add location search to your globe or map.
|
The Places Search appears as a new additional tab in Search, displaying the custom label and any query field label and suggestion you added. |
| Query an external postgres database and return polygons, lines, or geometries. | Write a custom search plug-in using the Python-based framework for search tabs. The ExampleSearch search plug-in is a useful demonstration for this purpose.
|
Your custom search plug-in appears as a new additional tab in Search, displaying the custom label and any query field label and suggestion you added. Alternatively, you can send HTTP requests and receive a response within your own custom web application. |

Comments are now code.
Code describes itself.
It's the simplest pattern.
But the hardest as well.

Oh the love our generation can have for a nice pair of white sneakers. In a time where the infamous Common Projects are all the hype, I wanted something more than just a good quality white sneaker. I spent many hours researching the most sustainable alternatives to Common Projects’ Achilles Low and BBall Low. In my search I was able to find about 7 different companies making high quality cruelty-free white sneakers which I felt have a design similar to Common Projects, 4 of which I will be highlighting in this blog post. If you’re like me and prefer the more ethical and sustainable choice when it comes to fashion, I have provided a list of cruelty-free white sneakers which do not compromise on quality.
This is one of my go-to pairs in my closet. Grenson has been perfecting their genuine leather line for a while now so it is nice to see they've branched out with their same methods in a more ethical collection.
Shop NowAs far as quality goes, these are by far the most durable and comfortable vegan sneakers I've worn. Eden is another pair they sell which give a slight nod to the AF1 / BBall look.
Shop NowThe minimal silhouette on these offers one of the cleanest looks I've come across for a vegan sneaker. I've yet to try a pair myself, but these seem like a promising alternative.
Shop NowIf you are a fan of innovative material, these may be the sustainable option you're looking for. They use a raw material known as bio-polyols which contains polymers extracted from cereals. Similar to Humans Are Vain, Irori is Yatay's own take on the AF1 / BBall sneaker.
Shop NowNow of course in the end, I believe secondhand purchases are the most sustainable option. Websites like Grailed and Depop are constantly selling barely worn Common Projects sneakers. However, this list was created to promote the brands who are making a difference and contributing to a more conscious and animal-free lifestyle.
I have provided an additional list below of some of the other brands I found in my research. If you’re still reading this then I’m assuming sustainable fashion is something you have an interest in. Whether this is true or not, I hope this list has helped you in your effort to make more conscious purchases this year.


Speech
Education Secretary Nicky Morgan discusses changes to the English Baccalaureate (EBacc) at King Solomon Academy, London.
Thank you so much for the invite and thank you to year 7 for that great performance.
One of the best things about my job is meeting pupils and teachers from across the country.
To see what’s working, to find out what’s not, and to learn what more I can do to help make our schools and classrooms truly exceptional.
Because what I want from education, what I passionately believe our education system should do, is give every single young person the chance to make the most of their talent.
And from everything I’ve seen and heard about this wonderful school, that’s exactly what you do, and it’s why I’m so delighted to be here today.
Every student at this school has the chance to go to a school totally and utterly focused on helping every single young person that walks through its doors, regardless of their background, to achieve whatever they want in life.
Because as the Prime Minister said on 8 May after he was re-elected, we are committed to governing as one nation. Nowhere is that more important than in education, where that commitment means giving every young person whatever background, wherever they’re from, the same opportunity to fulfil their potential.
I know how hard all of you in this school work, from teachers and support staff, to you, the pupils.
And the reason that is so important, is as I so often say, we know that a great education really sets you up for the future.
What you’ve learnt here so far - what you’ve achieved here - will stay with you for the rest of your lives. Which is why it’s so important that you learn the right things and learn them well.
It’s why at this school, almost all of you study the core academic subjects at GCSE , the subjects that keep your options open, and allow you to enter the widest ranges of careers and university courses.
We call it the English Baccalaureate, or EBacc .
Which means getting good passes in English, maths, sciences, history or geography and a language at GCSE .
And let me be crystal clear, this isn’t because I think that the arts subjects are in any way less good or in any way less valuable.
On the contrary, our country would be much the poorer if we were to fail to inspire the next generation of Henry Hollands, Olivia Colemans or Tinie Tempahs, or the next great orchestra.
What good schools like King Solomon Academy show is that there doesn’t need to be a false choice between an academic or an arts-based curriculum. You can do them both and you can do them both well.
As Max has said, here:
a fully rounded curriculum includes participating in a full string orchestra like I just heard, residential trips, quality work placements and performing unabridged Shakespeare plays.
Our pupils’ achievements in these activities, alongside the core academic subjects, allow them to study from the full range of subjects at A level and keep open as many options as possible for university and beyond.
And increasingly in the careers of the future - many of which don’t yet exist - that’s exactly what you’ll need to succeed. Just look at one of the fastest growing industries in this country, ‘app design’, which requires both knowledge and creativity in abundance. You might be surprised to know that when I was at school we had no mobile phones or apps. The only apple you had was the one you ate.
To me it seems obvious, that as many young people who are able should be studying these subjects up until 16. Not because we think that they’re the only subjects you should study but because they give you that flexibility and choice, down the line.
But the truth is, not all young people get the opportunities you do. Across the country, thousands of students are missing out.
Because they were told that academic subjects weren’t for them, because it was easier to pass a less demanding course, because young people were never told which doors would close by not studying these subjects. All making it harder for them to get a good job, an apprenticeship or a university place.
And the worst thing of all is that it’s the poorest young people who are most likely to miss out, with disadvantaged pupils only half as likely to be entered for the EBacc as their classmates.
And as research published last week by the Sutton Trust showed this has absolutely nothing to do with ability.
The brightest pupils at primary school - those in the top 10% nationally - were still less likely to take history, geography, a language or triple science at GCSE than their peers, if they are eligible for free school meals.
For every young person, no matter what their background, we don’t think that’s fair and neither does this school.
Every single one of you - every single person in this country - deserves the chance to get these qualifications at school.
No matter where you come from or what you want to do in life, no doors should be closed to you.
Because the world is now smaller than ever before. When your generation applies for university places, apprenticeships or jobs, you won’t just be competing against someone from down the road. You’ll be competing against young people across the world - so you’ll need the sort of qualifications, skills and experience that will help you to stand out.
So we are determined to make sure that the sort of excellence and high aspirations I’ve seen here this afternoon at King Solomon Academy are spread right across the country.
That’s why we promised in our manifesto that we’d work closely with teachers and heads to work out how we make sure that every child has the chance to study these crucial subjects. And that is what I’m committing to delivering today.
I know this will be a big change. There may be a small group of pupils for whom this won’t be appropriate. But our goal is for pupils starting year 7 this September to study the EBacc subjects when they reach their GCSEs .
It’s an ambitious goal and it’s the right thing to do.
To give every single young person in this country the very best start in life.
That’s what we mean when we talk about social justice, recognising the power of education to transform lives, break down barriers and open up a world of opportunities.
The other big change that I’m announcing today is about the grading system we’ll use for the new GCSEs that start being taught this September.
As some of you might know, we’re already replacing the old system of A* to U with a new scale of 9 to 1.
And today I’ve confirmed that the ‘good pass’ will be set at a grade 5. That’s at the top of the current grade C and the bottom of the current grade B.
To be sure, it’s a step up from where we are now and really does raise the bar. It brings us in line with the expectations that top performing countries like Finland, Canada, the Netherlands and Switzerland have for their students.
And as I said earlier, for your generation it isn’t good enough for you just to be top of your class, or the best in your neighbourhood. You need to be able to show that the qualifications you’ve earned and worked hard for can go toe-to-toe with your peers from across the globe.
We also know that you can only do your best and reach these new higher standards, if you’re able to learn in an environment which is calm, supportive and well-behaved as I’ve seen here myself this afternoon.
That’s why it’s so important that alongside setting higher standards, we do more to tackle bad behaviour.
The good news is that our schools and classrooms are actually better behaved than they’ve been at almost any point in history.
In fact we’ve done a lot over the past 5 years to help teachers tackle bad behaviour by giving them better guidance, protection and support.
We’ve scrapped the rules stopping teachers from taking control of the classroom and ensured that heads’ decisions on expulsions can no longer be overruled.
But as every teacher knows, it’s not just serious behaviour issues that can get in the way of teaching and learning.
Low-level disruption, especially when it’s happening daily, can be just as damaging.

I’m sure you’ve all seen or heard, perhaps from other schools, someone talking at the back of the class or someone’s mobile phone going off in the middle of a lesson.
And it’s not always easy for teachers to challenge something like that. Especially when they’re new to the classroom.
So this government is going to do everything we can to support teachers to manage this low-level disruption.
And in particular I am delighted to announce that Tom Bennett, a renowned behaviour expert, has agreed to chair a working group to look at behaviour content in training for new teachers building on the best evidence about what works to help them manage classrooms and manage behaviour.
I hope he’ll take a visit here to King Solomon Academy to find out how you do it.
In a couple of years’ time, school will be just a memory for all of you, although I hope some of you do decide to become teachers. And judging by the conversations I’ve had, it’ll be a very happy one.
As you make your way through life, you’ll be surprised how often you think back to what you learnt here at King Solomon Academy both in and out of lessons.
And just as important as your grades, your hard work and determination, the dedication and support of your teachers, will help you make the best possible start to your future.
That’s what we want for every single young person in this school and right across the country.

Thank you again to all of you and your teachers for hosting us here today.
And I wish you all the very best of luck with your studies.
Like your teachers and parents, your friends and families, the government is standing right behind you. Supporting you, and young people like you all over the country, to truly be the best that you can be.
Thank you.

Firewall Application¶
- Suppose we would like to implement a simple firewall application to enforce the following access control policy for a network topology that all of the hosts belong to the same subnet.
| H1 (<IP_ADDRESS>) | (H2) <IP_ADDRESS> | (H3) <IP_ADDRESS> | H4(<IP_ADDRESS>) | |
|---|---|---|---|---|
| H1(<IP_ADDRESS>) | NONE | DENY | WEB | DENY |
| H2(<IP_ADDRESS>) | DENY | NONE | DNEY | PING |
| H3(<IP_ADDRESS>) | WEB | DENY | NONE | DENY |
| H4(<IP_ADDRESS>) | DENY | DENY | PING | NONE |
- To achieve that goal, we implement an application using Umbrella APIs to generate and install appropriate forwarding rules on the switches between each pair of hosts: (h1,h3) and (h2, h4). We explain step by step how to write the mentioned application:
- First, we need to create an instance of the controller that we would like to execute our application on. We assume that the name of controller will be passed as an argument to the forwarding application.
if (args.length < 1) {
System.out.println("Arguments: onos/odl");
}
Controller controller;
if (args[0].equalsIgnoreCase("onos")) {
controller = new OnosController();
} else if (args[0].equalsIgnoreCase("odl")) {
controller = new OdlController();
} else {
return;
}
- Second, we need to get the list of currents hosts and find a shortest path for each pair of hosts: (h1, h3) and (h2,h4).
- Third, we generate appropriate match-action fields for each pair of hosts based on the type of traffic which is specified in the table above. For the pair (h1, h3), we should use source and destination TCP ports (i.e. port 80 for web traffic) to route web traffic and for the pair (h2, h4) we should use ICMP type and code match fields (i.e. type=8 (echo request), type=0 (echo reply) and code=0) to route ICMP traffic. Note that for both types of traffic, we also use source and destination MAC addresses, source and destination IP addresses, Ethernet type, and IP protocol number as the match fields.

Testing the Forwarding Application on ONOS controller¶
- In this section, we explain a Mininet simulation scenario that can be used to test the forwarding application on ONOS controller:
First, you need to install and run ONOS on your local machine using the guidelines that have been posted on ONOS website: ONOS GUIDES
Second, you need to download and install Mininet using the guidelines that have been posted on Mininet website: Mininet
Third, execute the following commands to run a Mininet simulation scenario that simulates a leaf-spine network topology with 6 hosts:
$ cd mininet_examples $ sudo python leaf_spine.py
Forth, run pingall to detect all of the hosts in the network topology. ONOS runs a reactive forwarding application by default.
Fifth, package umbrella source codes using the following command:
$ mvn package
Finally, execute the application using the following command to install rules on network switches:
$java -cp target/umbrella-1.0-SNAPSHOT-jar-with-dependencies.jar apps.Firewall onos

--send-file-paths /bucket/dir/file.txt
, parent directory is
/bucket/dir/
) to temporarily store a processed AS2 message file,
store the MDN when we receive them from the partner, and write a
final JSON file containing relevant metadata of the transmission.
So, the AccessRole
needs to provide read and write access to the
parent directory of the file location used in the
StartFileTransfer
request. Additionally, you need to provide read
and write access to the parent directory of the files that you
intend to send with StartFileTransfer
.
If you are using Basic authentication for your AS2 connector, the
access role requires the secretsmanager:GetSecretValue
permission
for the secret. If the secret is encrypted using a customer-managed
key instead of the Amazon Web Services managed key in Secrets
Manager, then the role also needs the kms:Decrypt
permission for
that key.
For SFTP connectors
Make sure that the access role provides read and write access to the
parent directory of the file location that's used in the
StartFileTransfer
request. Additionally, make sure that the role
provides secretsmanager:GetSecretValue
permission to Secrets
Manager.

Hey there, my name is Pratik, and I am currently pursing my undergraduate degree in the college of engineering at Illinois. I love working on anything that has to do with data and application development. Currently, I am seeking a software development internship in the summer of 2018. While I am not coding, I am probably travelling the world, biking, or reading.
