OVERVIEW:
Integral, a management consultant firm, has served world class clients with Design Thinking coaching, design and consultancy services since 2005. Working on one of their products, UX Design Mastery, was a herculean task for me. Later renamed as ‘UX Coach Me’.
I designed and conceptualised the whole on-boarding online experience for the target users. The users aim to learn UX Design from Integral, a U.K. based management consultancy firm.
THE GOAL
Design Challenge: Create an online onboarding experience for the candidates where they can access lessons and get rewarded.
The Solution: I designed a minimalist and intuitive dashboard navigation where candidates could access their lessons, interact and engage not just with the coach but also with the community.
MY ROLE IN THE TEAM:
UX Researcher
UX Designer
Conceptualization
Different UX methods used were:
My process was intensive with double-diamond approach where I worked in a remote team.
Double Diamond as you might be aware: is a structured design approach to tackle challenges in four phases:
Discover or Research— insight into the problem (diverging)
Define or Synthesis — the area to focus upon (converging)
Develop or Ideation— potential solutions (diverging)
Deliver or Implementation— solutions that work (converging)
User-Research
I started first with carrying on research on my user personas interviews, stakeholder interviews, technology and market analysis.
User-Persona Analysis
After my interviews with user-personas, I created a user-persona analysis mood-board. More personalised, real user-personas are useful as a reference while creating content structure, flow of the dashboard, UI kit, and designing the entire chain of engagement and usability.
A User-Persona, Laura Falk, wants to have the following with UX Coach:
Competition Analysis
After the research on user and interviewing the stakeholder, I dived further deep into the market analysis and current competitors of the client.
Customer Journey
In order to get to know the target users’ behaviour better, I created a Customer Journey Map.
Concept Description
My focus was to design a personalised online onboarding UX Coach platform with valuable resources and network. This way I wanted to give a personalised experience to a user.
I further went on to sketch out the possible solutions and carve out lo-fi wireframes on its basis. My aim was to shape up the navigation that is easy-to-use, a platform that is engaging, and rewarding.
Many cups of coffee and iterations were involved in the conceptualising phase. Towards the end, I chose to go on with the version which lets a user easily access lessons, engage with their preferred content like videos, chat with the coach via chatbox, feel rewarded.
Technical Considerations: In the initial design, the user Signs Up through Facebook. However, while I was in the designing and iterating phase of the prototype, Facebook made some technical changes. This brought technical complications for the app to sign up through Facebook. Hence, the final design has Sign Up where the first-time user has to register himself to access the courses.
The navigation and the features like chat with the coach, users being awarded on completion of each course (based on gamification concept), would be used in making. This project will go live in 2021. I'm excited! :)

Executables view
The Executables view provides a dynamic list of executables and their related source files. The Executables view makes it easy to:
- target all binaries for debugging because the symbolics are automatically loaded when a bld.inf is imported or a project is created from a template
- debug a binary that is not part of a project in the workspace by importing it into the Executables view to load the symbolics
- debug a process running on a device by attaching to the process and importing the binaries associated with the process into the Executables view to load the symbolics. For example, you to debug a library loaded by the process, you would need to import the libary and the process executable.
- remove binaries when a project is closed or deleted from the workspace
- remove binaries imported from outside the workspace by deleting the binary from the Executables project in the Project Explorer view
- locate and manage which source and resource files are associated with each executable. Paths shown in black text have been resolved, those in gray text cannot be found.
- identify and correct any path issues with missing source files (shown in gray text). Double-click the missing source file to open a Locate File editor view which enables you to find the missing file.
- view routines and header files used by the source file. Click the tree control to expand or collapse a list of included header files and routine names for fast navigation.
- find and set breakpoints, watchpoints, and eventpoints in source files. Double-click a source file to open it in an editor view and to review the status of its breakpoints.
In addition, an Executables project is created in the Project Explorer view. The binaries shown in the Executables project can be deleted which also removes them from the Executables view. For binaries outside the workspace you must import them into the Executables view so their symbolics can be used during the debug session. You can also drag and drop executables into the view.
The Executables view consists of the Executable Name and Source File Name panes described in the table below. Use the Columns button in the toolbar to show or hide specific columns in each pane. Columns can be sorted and rearranged in the order desired.
| Pane | Explanation |
|---|---|
| Executable Name | Displays a list of executables in the workspace as well as other files added by the user. Select an executable to update the Source File Name pane with related files. The executable information shown can include:
Click the Columns icon () to set which columns to show in this pane. |
| Source File Name | Displays a list of source files for the selected executable as extracted from the symbol table. The source file information shown can include:
Expand a file's tree control to view the functions and header files used by the file. Double-click to open the source file for editing or to set breakpoints. Click the Columns icon () to set which columns to show in this pane. |

Twitter / Amanda Palmer: "Habit is the death of vis ...
"Habit is the death of vision." - Earon Davis
A short sound "bite" that is actually less useful than it looks. It should say something a little less pithy like "Poor habits can be the death of many valuable resources like time, energy and growth. Uncritical, habitual, thinking is the death of vision". However the value of cultivating good habits has been know for millennia
"We are what we repeatedly do. Excellence then, is not an act, but a habit." - Aristotle
So the trick is adopt good habits and unlearn the bad ones.
How to uncover bad habits:
- Try and be conscious of what you do at all time
- Ask the people around you (family, close colleagues, friends)
- Keep a time log
- Film yourself using your PC with a webcam
- Review your day and consider what could have been better (the rule of threes -- note three things that were good and three things that need to be improved)
What are some examples of bad habits:
- Procrastination
- Snacking on junk food
- Worrying about other peoples opinions and using what you guessed they thought to be beat yourself up
- Thinking that your state of mind is dependent on others peoples' actions instead of it being your responsibility
- Being critical of other people and concerned with what they do when it has no direct affect on you
- Dwelling on missed opportunities and thinking "if only...."
- Picking your nose, not covering your mouth when you cough etc.
- Worrying about things without being able to use the thoughts to improve the outcome
Here some some suggestions for good habits:
- Review your habits and look for improvements
- Get enough sleep
- Get up early enough to make full use of the day
- Know what you need to do and get it done (people write books on that, I used their ideas and wrote a post)
- Love and like as many people as you can
- Shower daily, clean your teeth and wear clean clothes
- Set yourself goals to learn or experience new things
- Help others as much as you can
- Ask for help if you need it
- Smile and be courteous - remember most things that people do which annoy you are mistakes or bad habits, not deliberate attempts to upset you, you are not that important.
- Plan and think things through, then don't dwell on them in a negative spiral of worry
- Look after yourself
How to unlearn bad habits:
I struggle with this, as do most people, and I'm not a psychologist so the advice is a bit mundane
- Elastic band on the wrist - ping yourself when you catch yourself doing it
- Ask friends to remind if they see you doing something
- Substitute. e.g. carry fruit and veg to eat instead of buying chocolate
- Try and make the habit redundant. e.g. Plan projects so that you feel in control and can stop worrying about them
- Remove triggers. If certain places or activities trigger a bad habit then try and avoid them
- Give yourself some credit and don't do it all at once
- Try and look at the root cause when you catch yourself. e.g. are you procrastinating because you think you won't succeed? Are you not planning because your system is too complicated to use?
Finally
Use tools and techniques that support your good habits e.g. mind mapping tools to help you brainstorm improvements. Make sure they work for you.

Piers Morgan brands Prince Andrew interview 'desperate toe curling bulls**t'
The ITV Good Morning Britain host praised BBC Newsnight interview Emily Maitlis' 'forensic' interview skills - but did not rate the Duke of York's performance at all
by Talia Shadwell, https://www.mirror.co.uk/authors/talia-shadwell/Piers Morgan has offered a scathing review of Prince Andrew's performance in his first interview on his links with paedophile billionaire Jeffrey Epstein.
While the ITV Good Morning Host had praise for BBC Newsnight Emily Maiitlis' "brilliant forensic" interviewing skills during the hour-long probe that aired tonight, his appraisal of the Duke of York's delivery was less flattering.
"Desperate, toe-curling bullsh*t from Prince Andrew", tweeted Morgan.  Insane."
Prince Andrew's extraordinary appearance on BBC Two tonight came as the royal faces intense scrutiny over his links to the disgraced financier.
Epstein was found dead in his New York prison cell in March by apparent suicide as he awaited trial on sex trafficking charges.
In 2010, the prince was photographed walking with Epstein in New York's Central Park - two years after Epstein's first conviction for soliciting a minor for prostitution.
In a wide-ranging interview broadcast on the BBC tonight, the prince claimed he had never even met Virginia Giuffre, formerly Virginia Roberts, who has accused him of having sex with her when she was 17.
The prince told Maitlis he had did not recall meeting Ms Giuffre - also disputing the veracity of a photograph of him with his arm looped around the teenager.
Actress Rose McGowan, a prominent figurehead in the #MeToo movement, also tweeted her reaction to the interview.
She wrote: "Can Prince Andrew not remember Virginia Roberts, his accuser, because there were so many young girls? Am I hearing this right?"
McGowan also responded to Morgan's tweet about Prince Andrew's 'bullsh**t" performance, writing: I was wondering what you thought of this vile sh*t. I am nauseous. I know what his victims feel like, being ignored.
 Your monarchy is part of a predatory conspiracy. They need to fix this. Kudos to @maitlis."
Morgan responded, calling the interview: "excruciating."
The Duke of York told Maitlis he had been eating at Pizza Express with daughter Princess Beatrice on one night that Ms Giuffre claims she had sex with the prince when she was 17.
He said he recalled the dinner at the pizza branch in Woking for a party "weirdly distinctly" as it was such a rare occurrence.
When Maitlis asked the Prince about Ms Giuffre’s allegations that he was sweating when they danced in Tramp nightclub, the Prince said it was impossible.
“There’s a slight problem with the sweating,” he said.
“I have a peculiar medical condition.
“I didn’t sweat at the time because I had suffered what I would describe as an overdose of adrenaline in the Falklands War when I was shot at and I simply... it was almost impossible for me to sweat.”
The Prince has said he and Epstein were not as close friends as some have suggested, and told Maitlis his New York home was a "convenient place to stay."

Although those playing Mancala traditionally use a wooden board, this video shows two African children playing Mancala on the streets of their village without a board, as the game can be just as easily played using stones and by making holes in the ground.
After you've seen the video why not check out our instructions page for playing Mancala, download a version of the game or play online.
Whilst Ayo is often played with a board, and great care is taken to craft a board with its twelve carved out circular pockets and often elaborate carvings on its sides.
Ayo can also be played by simply marking out two rows of six pits in the ground, making the game more accessible to poorer people, especially children who can then simply play anywhere with sand or soft ground and a handful of stones or pebbles for playing pieces.
This short video shows how two kids playing Ayo / Awale.
Firstly you throw the sticks and for every stick that lands facing upwards you can make one step around the board. (There are four sticks, if, however none land facing up, you can make five moves.)
After the number of moves have been established you can start moving your pieces and each piece can move to an empty square or a square occupied by an opponent piece, in this case the two pieces switch positions. When two pieces of a player are adjacent to each other, those two pieces are safe and cannot be swapped. When 3 pieces are adjacent to each other, the pieces of another player cannot pass through them.
The last 5 squares are special squares, a piece is always safe on a safe square and will not be swapped, the fourth last square is the water square, when a piece lands on it, it must start from the beginning again. An exact throw is needed to leave the board.


7.12. Exclusive Control¶
Table of contents
This function performs exclusive control for updating data in the database. With this function, data integrity can be maintained even when the same data in the database is updated from multiple transactions (web or batch) at the same time.
Important
This function is deprecated because of the following reasons: Uses Universal DAO for exclusive control.
- Exclusive control of Universal DAO can be used more easily than this function.
- See Optimistic locking , Pessimistic locking.
- If the primary key is defined as a non-string type, this function cannot be used depending on the database.
- This function stores all the primary key values as string type ( java.lang.String ). When the primary key column definition is a non-string type (other than char or varchar), a SQL statement runtime exception occurs due to type mismatch depending on the database. For example, this problem occurs in the case of databases such as PostgreSQL where the implicit type conversion is not performed.
7.12.1. Function overview¶
<IP_ADDRESS>. Optimistic locking/Pessimistic locking are possible¶
This function performs optimistic locking/pessimistic locking by defining the version number column in the table. In this framework, the table in which the version number column is defined is called the exclusive control table.
The following can be realized with this function.
Since, the optimistic lock/pessimistic lock provided by this function is realized by using the same exclusive control table, even if optimistic lock and pessimistic lock are used in parallel, it is possible to prevent the same data from being updated at the same time. For example, web using optimistic lock and batch using pessimistic lock can run in parallel and still maintain the data integrity.
The exclusive control table is defined for each unit of exclusive control and the largest unit in which conflicts are allowed. For example, if the business allows locking in a large unit called “user”, an exclusive control table is defined in that unit. However, note that the possibility of conflict increases if the unit is increased, and update failure (in the case of optimistic locking) and processing delay (in the case of pessimistic locking) will occur.
Tip
Normally, the unit of the exclusive control table is defined from a business perspective. For example, when the sales and deposit processes are updated at the same time, the exclusive control table is defined in a unit of tables related to the processes.
Also, the unit of the exclusive control table can be defined from the perspective of table design. For example, if the parent-child relationship of the table such as the header (parent) and details (child) is clear, the exclusive control table is defined in parent units. If the parent-child relationship is not clear, determine which one should be the parent and then define the exclusive control table.
Important
Design the update order after designing the exclusive control table. Deadlock is prevented by determining the update order of each table, and data integrity during update is guaranteed. In a database, since row locks occur when records are updated, deadlocks are very likely to occur if the update order is not specified.

7.12.3. How to use¶
<IP_ADDRESS>. Prepare to use exclusive control¶
To use exclusive control, create a class that retains the configuration and information required for exclusive control.
- Configuration
Add the configuration of BasicExclusiveControlManager to the component definition.
 <component name="exclusiveControlManager" class="nablarch.common.exclusivecontrol.BasicExclusiveControlManager">  <property name="optimisticLockErrorMessageId" value="CUST0001" /> </component>
- Creating a class that holds the information required for exclusive control
Create by inheriting ExclusiveControlContext. This class is created for each exclusive control table and used in the API call that performs exclusive control.
-- Exclusive control table CREATE TABLE USERS ( USER_ID CHAR(6) NOT NULL, -- Business data other than the primary key is omitted. VERSION NUMBER(10) NOT NULL, PRIMARY KEY (USER_ID) )
// Class corresponding to the exclusive control table USERS. // Inherit ExclusiveControlContext. public class UsersExclusiveControl extends ExclusiveControlContext { // Define the primary key of the exclusive control table with enumeration type. private enum PK { USER_ID } // Define a constructor that takes the value of the primary key. public UsersExclusiveControl(String userId) { // Configure the table name with the setTableName method of the parent class. setTableName("USERS"); // Configure the version number column name with the setVersionColumnName method // of the parent class. setVersionColumnName("VERSION"); // Use the enum values method for the setPrimaryKeyColumnNames method // of parent class to set all primary key enumeration types. setPrimaryKeyColumnNames(PK.values()); // Add the primary key value using the appendCondition method of the parent class. appendCondition(PK.USER_ID, userId); } }
<IP_ADDRESS>. Optimistic locking¶
When the data to be updated is acquired, the version number of the table for exclusive control is obtained. The optimistic lock is achieved by checking whether the version number of the exclusive control table has been updated during the update.
Use HttpExclusiveControlUtil for optimistic locking.
Using the update function with input → confirmation → completion as an example, an implementation example of optimistic locking is shown below.
- Initial display of input screen
public HttpResponse index(HttpRequest request, ExecutionContext context) { // (Business process) // Get the primary key condition to acquire the update target data from the request. String userId = getUserId(request); // (Exclusive control) // Generate the primary key class and prepare the version number. // The acquired version number is configured in the ExecutionContext specified // by the framework. HttpExclusiveControlUtil.prepareVersion(context, new UsersExclusiveControl(userId)); // (Business process) // Acquire the update target data and configure it in the request scope // to display the input screen. context.setRequestScopedVar("user", findUser(userId)); return new HttpResponse("/input.jsp"); }
- Confirmation button on the input screen (Input → Confirm)
@OnErrors({ @OnError(type = ApplicationException.class, path = "/input.jsp"), @OnError(type = OptimisticLockException.class, path = "/error.jsp") }) public HttpResponse confirm(HttpRequest request, ExecutionContext context) { // (Exclusive control) // Check the update of version number. // Acquire the version number from the HttpRequest specified by the framework. // Since the OptimisticLockException will be thrown if the version number has been updated, // specify @OnError and the transition destination. HttpExclusiveControlUtil.checkVersions(request, context); // (Business process) // Check the input data and configure in the request scope // to display the confirmation screen. context.setRequestScopedVar("user", getUser(request)); return new HttpResponse("/confirm.jsp"); }
Important
The version numbers will not be inherited between screens, if ( HttpExclusiveControlUtil.checkVersions ) does not perform the version check.
- Update button on the confirmation screen (confirmation → complete)
@OnErrors({ @OnError(type = ApplicationException.class, path = "/input.jsp"), @OnError(type = OptimisticLockException.class, path = "/error.jsp") }) public HttpResponse update(HttpRequest request, ExecutionContext context) { // (Exclusive control) // Perform the update check of the version number and update. // Acquire the version number from the HttpRequest specified by the framework. // Since the OptimisticLockException will be thrown if the version number has been updated, // specify @OnError and the transition destination. HttpExclusiveControlUtil.updateVersionsWithCheck(request); // (Business process) // Check the input data and perform the update process. // Configure the updated data in request scope to the display completion screen. User user = getUser(request); update(user); context.setRequestScopedVar("user", user); return new HttpResponse("/complete.jsp"); }
<IP_ADDRESS>. Perform optimistic lock with batch update¶
In the process of collectively updating specific properties (such as logical deletion flag) for multiple records, performing optimistic lock check only on selected records may be preferred.
There are two implementation methods depending on whether the primary key of the exclusive control table is not a composite primary key or a composite primary key.
- Is not a composite primary key
An implementation example when the primary key is not a composite primary key is shown using the screen for batch deletion of users as an example. Since the acquire section of the version number just calls HttpExclusiveControlUtil#prepareVersions, implementation example is omitted.

 Delete target	 User name

  <checkbox name="user.deactivate" value="user001" />	 User 001

 <checkbox name="user.deactivate" value="user002" />	 ユーザ002

// (Exclusive control: Check) // Only the primary key of the user configured in the request parameter "user.deactivate" // is a check target. HttpExclusiveControlUtil.checkVersions(request, context, "user.deactivate");
// (Exclusive control: Check and update) // Only the primary key of the user configured in the request parameter "user.deactivate" // is a check target. HttpExclusiveControlUtil.updateVersionsWithCheck(request, "user.deactivate");
- For composite primary key
An implementation example when the primary key is a composite primary key is shown using the screen for batch deletion of users as an example. Since the acquire section of the version number just calls HttpExclusiveControlUtil#prepareVersions, implementation example is omitted.
-- Table with a composite primary key defined. CREATE TABLE USERS ( USER_ID CHAR(6) NOT NULL, PK2 CHAR(6) NOT NULL, PK3 CHAR(6) NOT NULL, -- Business data other than the primary key is omitted. VERSION NUMBER(10) NOT NULL, PRIMARY KEY (USER_ID,PK2,PK3) )
// Class corresponding to the exclusive control table USERS. public class UsersExclusiveControl extends ExclusiveControlContext { // Define the primary key of the exclusive control table with enumeration type. private enum PK { USER_ID, PK2, PK3 } // Define a constructor that takes the value of the primary key // and set the necessary information in the parent class method. public UsersExclusiveControl(String userId, String pk2, String pk3) { setTableName("USERS"); setVersionColumnName("VERSION"); setPrimaryKeyColumnNames(PK.values()); appendCondition(PK.USER_ID, userId); appendCondition(PK.PK2, pk2); appendCondition(PK.PK3, pk3); } }

 Delete target	 User name

   <input id="checkbox" type="checkbox" name="user.userCompositeKeys" value="user001,pk2001,pk3001" /> 	 User 001

  <input id="checkbox" type="checkbox" name="user.userCompositeKeys" value="user002,pk2002,pk3002" /> 	 ユーザ002

Tip
Composite primary keys are easier to handle when custom tag corresponding to the composite primary key and CompositeKey are used. For details, see Creating radio buttons and checkboxes associated with a composite key.
// (Exclusive control: Check) // Form implements the process of extracting the primary key from the request parameter // taking the delimiter into consideration. User[] deletedUsers = form.getDeletedUsers(); // Call the check by record. for(User deletedUser : deletedUsers) { HttpExclusiveControlUtil.checkVersion( request, context, new UsersExclusiveControl(deletedUser.getUserId(), deletedUser.getPk2(), deletedUser.getPk3())); }
// (Exclusive control: Check and update) User[] deletedUsers = form.getDeletedUsers(); // Call check and update by record. for(User deletedUser : deletedUsers) { HttpExclusiveControlUtil.updateVersionWithCheck( request, new ExclusiveUserCondition(deletedUser.getUserId(), deletedUser.getPk2(), deletedUser.getPk3())); }
<IP_ADDRESS>. Pessimistic locking¶
The pessimistic lock is realized by updating the version number of the exclusive control table before acquiring the update target data.
By updating the version number of the exclusive control table before acquiring the update target data, the target row of the exclusive control table is locked until the transaction of the update process is committed or rolled back. Therefore, the update process of other transactions is kept on wait until the lock is released.
Use ExclusiveControlUtil#updateVersion for pessimistic locking.
ExclusiveControlUtil.updateVersion(new UsersExclusiveControl("U00001"));
Important
In batch process, pre-processing to acquire only the primary key for locking is provided, and it is implemented in this process such that data is acquired and updated after acquiring one lock each. The reasons are as follows.
- To prevent other processes from updating the data between the time when the data is acquired and updated.
- The lock time should be kept as short as possible and keep its impact on parallel processing as small as possible.

A class to monitor events from the C++ side of things.
It maintains a set of "hooks", function pointers assigned to event names, and calls the appropriate hooks when the matching event is detected.
This class is not necessary when the hooks are detected and processed entirely by the scripting language, e.g. via Scheme hooks or the messenger in Python.
| __init__ | ( | EventQueue | ev_queue | ) |
| dispatchEvent | ( | const Event | event | ) |
Calls the hooks assigned to the indicated single event.

Sri Lanka touch down in Pakistan for historic tour
Cricket - Sri Lanka have touched down in Pakistan for a tour that will see the home country hosting Test cricket for the first time since the 2009 terrorist attack.
Eight people were killed and several players were wounded when the Sri Lanka team bus was shot at in Lahore in March 2009.
The majority of Pakistan's home Test matches have since taken place in the United Arab Emirates in the intervening years.
Pakistan Cricket Board (PCB) chief executive Wasim Khan said Sri Lanka's arrival marked an "historic occasion".
Sri Lanka played three ODIs and three T20 matches in Pakistan in September and October, but their upcoming tour of Pakistan marks the return of Test cricket to the country, with the first Test starting in Rawalpindi starting on Wednesday.
The second and final game of the series will be played in Karachi from 19 December.
"This is my first tour to Pakistan," said Sri Lanka captain Dimuth Karunaratne.
"After the 2009 incidents, players were scared to tour Pakistan but in the last two years or so Sri Lanka and other teams have toured Pakistan.
"We want to play good cricket in Pakistan and hope they give us some good security."
Khan added: "Pakistan's losses due to non-hosting of international cricket have been substantial.
"Pakistan cricket supporters have been denied the opportunity to see their heroes play live in our national stadiums."

Expo of products made of coconut shells
by Special CorrespondentThe Government Museum here organised a two-day expo of products made out of coconut shells as part of Coimbatore Day celebrations on Saturday and Sunday.
According to Nelson, who has made the products, nearly 50 kinds of items that will be useful in daily life are on display. These include cups, fruit bowls, soap and mobile phone stands, ladles, and water jugs.
Mr. Nelson started making these products two years ago and initially made only ladles. The product range was increased gradually. With increasing awareness on eco-friendly products, there was a demand for these, he said.
The products were improved based on customer feedback, he added.
According to museum curator C. Sivakumar, the museum promotes works of artisans in Coimbatore as part of Coimbatore Day (November 24) celebrations every year. This year, it has identified Mr. Nelson of Thallai Handicrafts. He said that coconut shells were available in plenty in the district and these were environment-friendly products that were used in earlier days. If the response for the expo was good, it would be extended for a day, the curator added.

Close shave for ro-ro passengers
Fishing boat rams ferry
by Special CorrespondentCommuters of the ro-ro ferry being operated in the Fort Kochi-Vypeen sector had a narrow escape after a fishing boat rammed its ramp at Kamalakadavu jetty at Fort Kochi on Thursday afternoon.
The service would have had to be cancelled had the ramp suffered a bent, sources said. The fishing boat fled from the scene. The ferry crew informed the coastal police, who in turn handed over the probe into the incident to the Fort Kochi police.
The ro-ro service was introduced a year ago after a recklessly-driven fishing boat rammed a ramshackle ferry being operated on the route over five years ago, resulting in the death of 11 commuters.

The day had begun for me at about 11:00am, which is actually pretty early for me, undisputably a night person. I began to engage in a typical morning's tedious activities (i.e. the common practices of hygene, satisfaction of hunger, etc.) when the phone rang. It was my friend Kim, who invited me to go to her apartment to smoke cannabis and converse as we'd been doing every Thursday for several weeks.
When I arrived at her place, she loaded the pipe and let me take the 'Green' like she always does. After we'd finished, we talked casually for a few minutes. I don't recall what prompted her, but her expression turned serious.
'This is going to make you mad...I tried to do something for you too, but I couln't.' She must have read my confusion, because she stood up and left the room. When she returned, she was carrying two very large bags of mushrooms.
Despite her expectations, I was actually very impressed; I'd never actually seen them before. I pulled my bag out and found a decent-sized bud, which I traded for two small caps and a couple stems. The stems had bruised blue, indicating their authenticity. I was overjoyed, even despite the small quantity I'd received.
I decided to eat them later that afternoon at a friends' sisters' house. I'd always heard the taste was terrible, but they seemed okay to me. I was with three friends, as well as another aquaintance, Steve, and his girlfriend. We joked and passed around a water-pipe. What I experienced about twenty minutes later definitely qualified as a drug-altered conciousness.
I remember the first effect I noticed was the change in sensation I felt throughout my body. The novelty was fantastic, so much different than marijuana or alcohol. A visual change took place shortly thereafter. Lights had a noticable haze over them, and colours seemed far brighter.
'Wow, these are really starting to work!' I proclaimed.
 She began to push her face close to mine, then pull it away quickly and repeat.
'I'm still coherent, though,' I grumbled, slightly annoyed. Still, the movement of her face hypnotised me, and I realized that her face was the only thing I could see. I watched her for a moment, when a sudden feeling of amusement overtook me. Amusement gave way to euphoria, and I could feel the peak coming.
During the next fourty minutes or so, I didn't speak or interact with the others, but I was still having an excellent time. The feelings I experienced were like no other I'd ever known. The sensation came over me that I could actually feel the two substances working on every cell in my body. My minds eye saw what was apparently two large transparent clocks with no numbers. I learned quickly that each was a representation of the drugs I had taken. I sat and smiled as I watched (strange as it may sound) my trip slowly tick away into normal conciousness. I was so taken by the experience that all I could do was flash a metal sign.
'Here's to natural drugs!' I gushed
Concerning my first experience with psylocybin, I regret only that I couldn't have consumed a larger dose. The time-space warp and sharpened abilities of self-relflection that a standard trip is alleged to offer do sound very intriguing. I call the experience my 'Sample-trip' because, much like samples of food in a grocery store, I only recieved a taste, an insignificant portion of the psychedelic experience. However, this sample did manage to fullfill the true goal of every sample, which is to set the customer's taste with a small amount in hope that they'll purchase the item in bulk. Needless to say, I'll do just that. I'll count the days until I can once again eat those cute little fungi and experience the outlawed miracles they tend to perform.

Switch to vaping 'helps smokers' hearts'
by James GallagherSmokers can improve the health of their hearts within weeks of switching to e-cigarettes, the largest trial of its kind shows.
The month-long study of 114 smokers suggests vaping has the potential to reduce heart attack and stroke risk.
The team, at the University of Dundee, stressed vaping was "not safe" - just less harmful than tobacco.
The British Heart Foundation said stopping smoking was the single best thing you could do for your heart.
Chemicals in cigarette smoke narrow arteries as they get furred up with fatty deposits increasing the risk of a deadly blockage. Ultimately smoking doubles your risk of having a heart attack.
But the researchers said the current evidence on vaping was "very poor" and often assessed the impact of a single e-cigarette on heart health.
So they monitored people's blood vessels a month after they were switched to e-cigarettes on the trial.
They focused on how blood vessels expand when a wave of blood rushes through, by measuring "flow-mediated dilation".
The more the blood vessels are able to expand the healthier they are. Flow-mediate dilation scores have been closely linked to the long-term risk of heart attacks and stroke.
The results, published in the Journal of the American College of Cardiology, showed:
- Healthy non-smokers had a score of 7.7%
- Smokers had a score of 5.5%
- But those who switched to nicotine e-cigarettes for a month had a score of 6.7%
So, switching to vaping got those smokers about halfway back to a healthy score.
"They're not quite normal, but their vascular function improved quite significantly, just within a month," said one of the researchers, Professor Jacob George.
The study is too short to fully establish whether or not this improvement could be sustained in the long-term or if vaping would definitely save lives.
It is also worth noting that vapers did not have a normal score.
Prof George added: "The key take-home is these devices are not completely safe and should not be tried by non-smokers or children.
"We now have clear evidence they're less harmful than tobacco cigarettes."
The potential dangers of vaping were highlighted this week when a British teenager told the BBC how e-cigarettes nearly killed him.
The devices set off a catastrophic immune reaction in his lungs that left him on life-support with his breathing replaced by an artificial lung.
But overall, the advice in the UK is that vaping is 95% safer than smoking and that smokers should switch and non-smokers should not take up vaping.
The British Heart Foundation said 50 people every day die as a result of heart problems caused by smoking.
"Stopping smoking is the single best thing you can do for your heart health," the charity said.
Prof John Britton, director of the UK centre for tobacco and alcohol studies at the University of Nottingham, said: "This randomised trial provides clear evidence of a reduction in a marker of cardiovascular disease risk in people who switch from smoking to vaping.
"The finding of the study, that vaping is less harmful than smoking, is intuitively correct on the grounds of the lower range and levels of emissions known to be present in vapour relative to tobacco smoke."

This tutorial is intended to give you a tour of the basic OVN features using
ovs-sandbox
as a simulated test environment. It’s assumed that you have an
understanding of OVS before going through this tutorial. Detail about OVN is
covered in [ovn-architecture(7)], but this tutorial lets you quickly see it in
action.
For some general information about ovs-sandbox
, see the “Getting Started”
section of [Tutorial.md].
ovs-sandbox
does not include OVN support by default. To enable OVN, you must
pass the --ovn
flag. For example, if running it straight from the ovs git
tree you would run:
$ make sandbox SANDBOXFLAGS=”--ovn”
Running the sandbox with OVN enabled does the following additional steps to the environment:
Creates the OVN_Northbound
and OVN_Southbound
databases as described in
[ovn-nb(5)] and [ovn-sb(5)].
Creates the hardware_vtep
database as described in [vtep(5)].
Runs the [ovn-northd(8)], [ovn-controller(8)], and [ovn-controller-vtep(8)] daemons.
Makes OVN and VTEP utilities available for use in the environment, including [vtep-ctl(8)], [ovn-nbctl(8)], and [ovn-sbctl(8)].
Note that each of these demos assumes you start with a fresh sandbox
environment. Re-run ovs-sandbox
before starting each section.
This first environment is the simplest OVN example. It demonstrates using OVN with a single logical switch that has two logical ports, both residing on the same hypervisor.
Start by running the setup script for this environment.
$ ovn/env1/setup.sh
You can use the ovn-nbctl
utility to see an overview of the logical topology.
$ ovn-nbctl show
lswitch 78687d53-e037-4555-bcd3-f4f8eaf3f2aa (sw0)
lport sw0-port1
addresses: 00:00:00:00:00:01
lport sw0-port2
addresses: 00:00:00:00:00:02
The ovn-sbctl
utility can be used to see into the state stored in the
OVN_Southbound
database. The show
command shows that there is a single
chassis with two logical ports bound to it. In a more realistic
multi-hypervisor environment, this would list all hypervisors and where all
logical ports are located.
$ ovn-sbctl show
Chassis “56b18105-5706-46ef-80c4-ff20979ab068”
Encap geneve
ip: “<IP_ADDRESS>”
Port_Binding “sw0-port1”
Port_Binding “sw0-port2”
OVN creates logical flows to describe how the network should behave in logical
space. Each chassis then creates OpenFlow flows based on those logical flows
that reflect its own local view of the network.  Before looking at the flows, we can use ovs-ofctl
to verify the
OpenFlow port numbers for each of the logical ports on the switch. The output
shows that lport1
, which corresponds with our logical port sw0-port1
, has an
OpenFlow port number of 1
. Similarly, lport2
has an OpenFlow port number of
2
.

The ovs-appctl
command can be used to generate an OpenFlow trace of how a
packet would be processed in this configuration. This first trace shows a
packet from sw0-port1
to sw0-port2
. The packet arrives from port 1
and
should be output to port 2
.
$ ovn/env1/packet1.sh
Trace a broadcast packet from sw0-port1
. The packet arrives from port 1
and
should be output to port 2
.
$ ovn/env1/packet2.sh
You can extend this setup by adding additional ports. For example, to add a third port, run this command:
View ovn/env1/add-third-port.sh.
$ ovn/env1/add-third-port.sh
Now if you do another trace of a broadcast packet from sw0-port1
, you will see
that it is output to both ports 2
and 3
.
$ ovn/env1/packet2.sh
This environment is an extension of the last example. The previous example
showed two ports on a single logical switch. In this environment we add a
second logical switch that also has two ports.  This first trace shows a packet from
sw0-port1
to sw0-port2
. You should see th packet arrive on OpenFlow port
1
and output to OpenFlow port 2
.
$ ovn/env2/packet1.sh
This next example shows a packet from sw0-port1
with a destination MAC address
of 00:00:00:00:00:03
, which is the MAC address for sw1-port1
. Since these
ports are not on the same logical switch, the packet should just be dropped.
$ ovn/env2/packet2.sh
The first two examples started by showing OVN on a single hypervisor. A more realistic deployment of OVN would span multiple hypervisors. This example creates a single logical switch with 4 logical ports. It then simulates having two hypervisors with two of the logical ports bound to each hypervisor.
$ ovn/env3/setup.sh
You can start by viewing the logical topology with ovn-nbctl
.
$ ovn-nbctl show
lswitch b977dc03-79a5-41ba-9665-341a80e1abfd (sw0)
lport sw0-port1
addresses: 00:00:00:00:00:01
lport sw0-port2
addresses: 00:00:00:00:00:02
lport sw0-port4
addresses: 00:00:00:00:00:04
lport sw0-port3
addresses: 00:00:00:00:00:03
Using ovn-sbctl
to view the state of the system, we can see that there are two
chassis: one local that we can interact with, and a fake remote chassis. Two
logical ports are bound to each. Both chassis have an IP address of localhost,
but in a realistic deployment that would be the IP address used for tunnels to
that chassis.
$ ovn-sbctl show
Chassis “56b18105-5706-46ef-80c4-ff20979ab068”
Encap geneve
ip: “<IP_ADDRESS>”
Port_Binding “sw0-port2”
Port_Binding “sw0-port1”
Chassis fakechassis
Encap geneve
ip: “<IP_ADDRESS>”
Port_Binding “sw0-port4”
Port_Binding “sw0-port3”
Packets between sw0-port1
and sw0-port2
behave just like the previous
examples. Packets to ports on a remote chassis are the interesting part of this
example. You may have noticed before that OVN’s logical flows are broken up
into ingress and egress tables. Given a packet from sw0-port1
on the local
chassis to sw0-port3
on the remote chassis, the ingress pipeline is executed
on the local switch. OVN then determines that it must forward the packet over a
geneve tunnel. When it arrives at the remote chassis, the egress pipeline will
be executed there.
This first packet trace shows the first part of this example. It’s a packet
from sw0-port1
to sw0-port3
from the perspective of the local chassis.
sw0-port1
is OpenFlow port 1
. The tunnel to the fake remote chassis is
OpenFlow port 3
. You should see the ingress pipeline being executed and then
the packet output to port 3
, the geneve tunnel.
$ ovn/env3/packet1.sh
To simulate what would happen when that packet arrives at the remote chassis we
can flip this example around. Consider a packet from sw0-port3
to
sw0-port1
. This trace shows what would happen when that packet arrives at the
local chassis. The packet arrives on OpenFlow port 3
(the tunnel). You should
then see the egress pipeline get executed and the packet output to OpenFlow port
1
.
$ ovn/env3/packet2.sh
While OVN is generally focused on the implementation of logical networks using overlays, it’s also possible to use OVN as a control plane to manage logically direct connectivity to networks that are locally accessible to each chassis.
This example includes two hypervisors. Both hypervisors have two ports on them. We want to use OVN to manage the connectivity of these ports to a network attached to each hypervisor that we will call “physnet1”.
This scenario requires some additional configuration of ovn-controller
. We
must configure a mapping between physnet1
and a local OVS bridge that provides
connectivity to that network. We call these “bridge mappings”. For our
example, the following script creates a bridge called br-eth1
and then
configures ovn-controller
with a bridge mapping from physnet1
to br-eth1
.
$ ovn/env4/setup1.sh
At this point we should be able to see that ovn-controller
has automatically
created patch ports between br-int
and br-eth1
.
$ ovs-vsctl show
aea39214-ebec-4210-aa34-1ae7d6921720
Bridge br-int
fail_mode: secure
Port “patch-br-int-to-br-eth1”
Interface “patch-br-int-to-br-eth1”
type: patch
options: {peer=”patch-br-eth1-to-br-int”}
Port br-int
Interface br-int
type: internal
Bridge “br-eth1”
Port “br-eth1”
Interface “br-eth1”
type: internal
Port “patch-br-eth1-to-br-int”
Interface “patch-br-eth1-to-br-int”
type: patch
options: {peer=”patch-br-int-to-br-eth1”}
Now we can move on to the next setup phase for this example. We want to create
a fake second chassis and then create the topology that tells OVN we want both
ports on both hypervisors connected to physnet1
. The way this is modeled in
OVN is by creating a logical switch for each port.
You can use ovn-nbctl
to see that this port has a type
and options
set.
$ ovn-nbctl lport-get-type provnet1-1-physnet1
localnet
$ ovn-nbctl lport-get-options provnet1-1-physnet1
network_name=physnet1
The physical topology should reflect that there are two regular ports on each chassis.
$ ovn-sbctl show
Chassis fakechassis
Encap geneve
ip: “<IP_ADDRESS>”
Port_Binding “provnet1-3-port1”
Port_Binding “provnet1-4-port1”
Chassis “56b18105-5706-46ef-80c4-ff20979ab068”
Encap geneve
ip: “<IP_ADDRESS>”
Port_Binding “provnet1-2-port1”
Port_Binding “provnet1-1-port1”
All four of our ports should be able to communicate with each other, but they do
so through physnet1
. A packet from any of these ports to any destination
should be output to the OpenFlow port number that corresponds to the patch port
to br-eth1
.
This example assumes following OpenFlow port number mappings:
br-eth1
provnet1-1-port1
provnet1-2-port1
We get those port numbers using ovs-ofctl
:
$ ovs-ofctl show br-int

OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0
This first trace shows a packet from provnet1-1-port1
with a destination MAC
address of provnet1-2-port1
. Despite both of these ports being on the same
local switch (lport1
and lport2
), we expect all packets to be sent out to
br-eth1
(OpenFlow port 1). We then expect the network to handle getting the
packet to its destination. In practice, this will be optimized at br-eth1
and
the packet won’t actually go out and back on the network.
$ ovn/env4/packet1.sh
This next trace is a continuation of the previous one. This shows the packet
coming back into br-int
from br-eth1
. We now expect the packet to be output
to provnet1-2-port1
, which is OpenFlow port 4.
$ ovn/env4/packet2.sh
This next trace shows an example of a packet being sent to a destination on
another hypervisor. The source is provnet1-2-port1
, but the destination is
provnet1-3-port1
, which is on the other fake chassis. As usual, we expect the
output to be to OpenFlow port 1, the patch port to br-et1
.
$ ovn/env4/packet3.sh
This next test shows a broadcast packet. The destination should still only be OpenFlow port 1.
$ ovn/env4/packet4.sh
Finally, this last trace shows what happens when a broadcast packet arrives
from the network. In this case, it simulates a broadcast that originated from a
port on the remote fake chassis and arrived at the local chassis via br-eth1
.
We should see it output to both local ports that are attached to this network
(OpenFlow ports 3 and 4).
$ ovn/env4/packet5.sh
This example is an extension of the previous one. We take the same setup and
add two more ports to each hypervisor. Instead of having the new ports directly
connected to physnet1
as before, we indicate that we want them on VLAN 101 of
physnet1
. This shows how localnet
ports can be used to provide connectivity
to either a flat network or a VLAN on that network.
$ ovn/env5/setup.sh
The logical topology shown by ovn-nbctl
is similar to env4
, except we now
have 8 regular VIF ports connected to physnet1
instead of 4. The additional 4
ports we have added are all on VLAN 101 of physnet1
. Note that the localnet
ports representing connectivity to VLAN 101 of physnet1
have the tag
field
set to 101
.

Port_Binding “provnet1-3-port1”
Port_Binding “provnet1-8-101-port1”
Port_Binding “provnet1-7-101-port1”
All of the traces from the previous example, env4
, should work in this
environment and provide the same result. Now we can show what happens for the
ports connected to VLAN 101. This first example shows a packet originating from
provnet1-5-101-port1
, which is OpenFlow port 5. We should see VLAN tag 101
pushed on the packet and then output to OpenFlow port 1, the patch port to
br-eth1
(the bridge providing connectivity to physnet1
).
$ ovn/env5/packet1.sh
If we look at a broadcast packet arriving on VLAN 101 of physnet1
, we should
see it output to OpenFlow ports 5 and 6 only.
$ ovn/env5/packet2.sh
ACLs provide a way to do distributed packet filtering for OVN networks. One example use of ACLs is that OpenStack Neutron uses them to implement security groups. ACLs are implemented using conntrack integration with OVS.
Start with a simple logical switch with 2 logical ports.
$ ovn/env6/setup.sh
A common use case would be the following policy applied for sw0-port1
:
The following script applies this policy to our environment.
$ ovn/env6/add-acls.sh
We can view the configured ACLs on this network using the ovn-nbctl
command.
$ ovn-nbctl acl-list sw0
from-lport 1002 (inport == “sw0-port1” && ip) allow-related
to-lport 1002 (outport == “sw0-port1” && ip && icmp) allow-related
to-lport 1002 (outport == “sw0-port1” && ip && tcp && tcp.dst == 22) allow-related
to-lport 1001 (outport == “sw0-port1” && ip) drop
Now that we have ACLs configured, there are new entries in the logical flow
table in the stages switch_in_pre_acl
, switchinacl,
switchoutpreacl,
and
switchout_acl`.
$ ovn-sbctl lflow-list
Let’s look more closely at switch_out_pre_acl
and switch_out_acl
.
In switch_out_pre_acl
, we match IP traffic and put it through the connection
tracker. This populates the connection state fields so that we can apply policy
as appropriate.
table=0(switch_out_pre_acl), priority= 100, match=(ip), action=(ct_next;)
table=1(switch_out_pre_acl), priority= 0, match=(1), action=(next;)
In switch_out_acl
, we allow packets associated with existing connections. We
drop packets that are deemed to be invalid (such as non-SYN TCP packet not
associated with an existing connection).
table=1(switch_out_acl), priority=65535, match=(!ct.est && ct.rel && !ct.new && !ct.inv), action=(next;)
table=1(switch_out_acl), priority=65535, match=(ct.est && !ct.rel && !ct.new && !ct.inv), action=(next;)
table=1(switch_out_acl), priority=65535, match=(ct.inv), action=(drop;)
For new connections, we apply our configured ACL policy to decide whether to allow the connection or not. In this case, we’ll allow ICMP or SSH. Otherwise, we’ll drop the packet.
table=1(switch_out_acl), priority= 2002, match=(ct.new && (outport == “sw0-port1” && ip && icmp)), action=(ct_commit; next;)
table=1(switch_out_acl), priority= 2002, match=(ct.new && (outport == “sw0-port1” && ip && tcp && tcp.dst == 22)), action=(ct_commit; next;)
table=1(switch_out_acl), priority= 2001, match=(outport == “sw0-port1” && ip), action=(drop;)
When using ACLs, the default policy is to allow and track IP connections. Based
on our above policy, IP traffic directed at sw0-port1
will never hit this flow
at priority 1.
table=1(switch_out_acl), priority= 1, match=(ip), action=(ct_commit; next;)
table=1(switch_out_acl), priority= 0, match=(1), action=(next;)
Note that conntrack integration is not yet supported in ovs-sandbox, so the OpenFlow flows will not represent what you’d see in a real environment.
This blog post discusses OVN ACLs from an OpenStack perspective and also provides an example of what the resulting OpenFlow flows look like.


A design system is a set of visual and coded components that can be used like Lego blocks to rapidly develop and release products that:
The ESRD Design System (ESRD-DS) is a nascent system that serves the ESRD/EQRS communities. It includes:
Coming soon:
ESRD-DS is primarily intended to help facilitate design and development, so the primary users are ESRD designers and engineers. However, it can also be used by testers to validate visual and code implementation.
ESRD-DS is open for pull requests from the broader Github community, per guidelines laid out in this document. We expect contributions primarily from the ESX team and EQRS developers. Suggestions, requests, and feedback should be submitted as Github issues.
ESRD-DS is maintained by the Shared Excellence team at ManTech.
