3.10 Belbin Team Roles
Research showed that the most successful teams were made up of a diverse mix of behaviours; they had access to all nine Belbin Team Roles. A Team Role was defined by Dr Meredith Belbin as “A tendency to behave, contribute and interrelate with others in a particular way”. The value of Belbin Team Role theory lies in enabling an individual or team to benefit from self knowledge and adjust according to the demands being made by the external situation.
The concept was derived from a study of successful and unsuccessful teams competing in Business Games at Henley Management College, England. Managers taking part in the exercise were given a battery of psychometric tests and put into teams of varying composition. As time progressed different clusters of behaviour were identified as underlying the success of the teams. These successful clusters of behaviour were then given names. Hence the emergence of nine Team Roles shown with the distribution among British managers:1
| Roles | Belbin Types | ||
|---|---|---|---|
| Action-oriented: | Shaper | Implementer | Completer Finisher |
| 2.3% | 11.4% | 3.6% | |
| —— | ——- | ——- | ——- |
| People-oriented: | Co-ordinator | Teamworker | Resource Investigator |
| 26.2% | 18.2% | 33.2% | |
| —— | ——- | ——- | ——- |
| Thinking-oriented: | Plant | Monitor Evaluator | Specialist |
| 3.7% | 0.5% | 0.8% | |
| ===== | ====== | ======== | ======== |
This doesn’t mean that every team requires nine people! Most people will have two or three Team Roles that they are most comfortable with. Team Roles develop and mature. These may change with experience and conscious attention. Different Team Roles may come to the fore in response to the needs of particular situations.

| Submissions Open | January 5 2020 |
|---|---|
| Submission Deadline | February 15 2020 |
| Selected paper Notification | March 10 2020 |
| Symposium | March 27-28 2020 |
We, at IEEE Robotics and Automation Society Student Chapter, Vellore Institute of Technology, Chennai are driven towards providing gateways for students to excel in our field with efforts that are be salubrious to the rest of the world. In order to achieve that,
students with an inclination need to be identified at the grassroots level and groomed accordingly, with the best possible guidance from stalwarts of the industry, which would enable them to indulge in nifty research projects
that are worthy of commendation among the global fraternity.
To that end, we have organized an International-level Mega-event titled “International Symposium on Robotics and Automation” - ISRA 2020, on the 27th and 28th of March. This event is poised to feature a multitude of breakthroughs in the area of Robotics and Automation in our country and is primarily intended for the benefit of students.
The Symposium comprises two parts, namely Paper Presentation and Idea Presentation.
In our quest to leave no stone unturned, both sessions have been designed to incorporate participation from all categories of students right from the schooling level to the post-graduation level.
The topics for the presentation range from biomedical robotics to aerial and terrestrial guided vehicles, encompassing all critical realms of research and development including, but not restricted to intelligent robotics, security applications and mechanisms like mobile manipulators. Also being dealt with,
will be entries pertaining to the 4th wave of industrialization such as the internet of things, smart manufacturing and cognitive computing among others.
The Paper Presentation will function as an excellent platform for young, ambitious research students who have put their acquired knowledge and skill
to the fore and come forward to showcase their enterprising work. Exemplary presentations have an opportunity to get recognized profusely by virtue of the superlative reach of the event.
The Idea Presentation is chiefly conducted to cater to the multifarious desiderata of budding research aspirants who are at the outset of their professional careers, but nevertheless, would feature novel and path-breaking projects from all students. An audacious idea is the spark that ignites the wildfire of technological innovation, and the audience are bound to witness many an idea of said nature during the course of this session.
The Symposium would be embellished with an abundance of insightful interactions by eminent luminaries from the field of RAS and beyond, which would enrich the students with invaluable information and cognizance that would prove fruitful in the quests we wish our students to undertake and hope to be prepared for on the back of it.
The symposium proceeding will follow.
The best papers will be published accordingly.

Judge punishes man to sit in court for a day
by Special CorrespondentThe Additional Mahila Court has ‘detained’ a litigant in the court hall till the end of the day’s proceedings after punishing him for smoking cigarette outside the court hall, located on the first floor of the old Collectorate building.
Additional Mahila Court Judge R. Radhakrishnan was in the bench on Friday when he sensed cigarette smoking smell and directed the police and court staff to find out whether someone was smoking.
After finding a man smoking cigarette, the court staff and police caught him red-handed and produced him before the judge. After identifying him as G. Kumaresan from Pasumpon, who visited the court in connection with his case, the Judge made him sit in the court for the full day as a mark of punishment.
After the end of day’s proceedings, the Judge directed the police to register case against him after which, the Kenikarai police booked him under section 290 (public nuisance) of Indian Penal Code. As he was booked for bailable offence, the police released him on bail. He would be produced before the judge next week for further action, police said.


 The ﬁeld of neural network interpretability has formed in response to these concerns.  A fully Reinforcement Learning / self-play version of AlphaGo has beat the previous version.”

Frequently asked Questions:
Question: When is the best time to go rafting?
Answer: The best time to go is late March to October. It is when we think that the river is safest. If you are seeking a more action packed and thrilling time of year to go, then the spring months are the best. The spring is when the snowmelt is at its peak and the rivers have the most water in them. However, in the spring the minimum age is raised and those who want to raft this time of year must be a bit adventurous! The summertime is the best for families and those who are seeking a great way to cool off from the summer heat.
Question: How much do I need to spend to go rafting?
Answer: Check the Activities serction of our page to see our affordable packages.
Question: What’s the weather now in Riggins, Idaho?
Answer: Check our Home Page to see the current weather information.
Question: How can I reserve a trip to Salmon River Adventures?
Answer: Check our Reservation Page, you can reserve your trip online or call our hotline.
Question: Is rafting safe for kids?
Answer: Yes, rafting is safe for children too, but there are some exceptions of course. General rule is that people shouldn't bring babies on rafting tours, because even if it's the calmest river ever, babies are just too little to help themselves in any possible way.
Question: What measures does the Salmon River Adventures take to ensure safety?
Answer: Salmon Rivers is a licenced professional outfitter. We pride ourselves with having the best, professional guides in Riggins.


--- layout: post title: Cascalog Testing 2.0 ---
A few months ago I announced Midje-Cascalog, my layer of Midje testing macros over the Cascalog MapReduce DSL. These allow you to write tests for your Cascalog jobs in a style that mimics Cascalog's own query execution syntax. In this post I discuss midje-cascalog's 0.4.0 release, which brings tighter Midje integration and a number of new ways to write tests. I'll start with a refresher on the old syntax before debuting the new. If you're eager, add the following to your project.clj:
[midje-cascalog "0.4.0"]
Take the following Cascalog query:
(use 'cascalog.api) (let [src [["word"]]] (?<- (stdout) [?out-word] (src ?word) (str ?word " up!" :> ?out-word)))
Executing this code at the repl prints a single tuple with the string word up!
to standard out.
How would you go about testing that this is true? With midje-cascalog, you would swap out the ?<-
form for its testing equivalent: fact?<-
. Here's the same Cascalog test alongside a typical Midje test:
(let [src [["word"]]] (fact?<- [["word up!"]] [?out-word] (src ?word) (str ?word " up!" :> ?out-word))) (fact "+ should add two numbers." (+ 2 2) => 4)
I find that fact?<-
and fact?-
macros can be a bit confusing when you start mixing Cascalog and Midje tests, as they break the Midje pattern of <thing-to-test> => <expected-thing>
. The syntax updates fix all of this with a set of checker functions that mimic Midje's excellent set of collection checkers.
Midje-cascalog 0.4.0 introduces the produces
function, mirroring Midje's just
. Let's define a source of tuples and a query to test.
(use 'cascalog.api) (require '[cascalog.ops :as c]) (def src [[1 2] [1 3] [3 4] [3 6] [5 2] [5 9]]) ;; adds the values in each input tuple, sorts the output and returns ;; 2-tuples of the first number and the sum. [1 2] becomes [1 3], for ;; example. (def query (<- [?x ?sum] (src ?x ?y) (:sort ?x) (c/sum ?y :> ?sum)))
You can think of a query as a set of tuples waiting to be generated (through query execution). With Midje, you test sets using the just
checker:
(facts [1 2 3] => (just [1 2 3]) ;; true [1 2 3] => (just [1 2 3 4])) ;; false
The cascalog analog to just
is the produces
checker. produces
works like just
, but against queries instead of bare collections. Executing the following test shows that the query produces the expected set of pairs, in any order:
(facts query => (produces [[3 10] [1 5] [5 11]]) ;; true query => (produces [[1 5] [3 10] [5 11]])) ;; true
You can read this test as saying "query, when executed, produces [3 10], [1 5] and [5 11]. You can also check that a query doesn't produce a set of tuples by swapping out =not=> for =>:
(fact query =not=> (produces [["string!" 11] [1 5] [5 11]])) ;; true
Using the :in-order
keyword after the expected tuple sequence forces the test to respect ordering:
(facts query =not=> (produces [[3 10] [5 11] [1 5]] :in-order) ;; true query => (produces [[1 5] [3 10] [5 11]] :in-order)) ;; true
(:in-order
is really only helpful in cases where output is sorted, like our query above.)
The produces-some
checker tests that a query's output contains a subset of tuples:
(fact query => (produces-some [[5 11] [1 5]])) ;; true
Note that the behaviour of produces-some
is similar to the behavior of Midje's contains
collection checker.
As with produces, you can use the :in-order
keyword to force produces-some
to respect ordering. Gaps between tuples are okay.
(facts query =not=> (produces-some [[5 11] [1 5]] :in-order) ;; true query => (produces-some [[1 5] [5 11]] :in-order)) ;; true
Adding the :no-gaps
keyword introduces the constraint that tuples must also be contiguous:
(facts query =not=> (produces-some [[1 5] [5 11]] :in-order :no-gaps) ;; true query => (produces-some [[1 5] [3 10]] :in-order :no-gaps)) ;; true
produce-prefix
mimics the has-prefix
collection checker by checking that some set of tuples is produced at the beginning of the query's output. produces-prefix
implicitly assumes that tuples will be produced in order with no gaps:
(facts query => (produces-prefix [[1 5]]) ;; true query => (produces-prefix [[1 5] [3 10]])) ;; true
Similarly, produce-suffix
mimics the has-suffix
collection checker by checking that the supplied set of tuples is produced at the tail end of a query:
(facts query => (produces-suffix [[5 11]])) ;; true
In addition to the keyword options supported above, every one of these checkers supports on optional logging-level keyword. For example, the following two facts are equivalent, but the second one produces :info
level logging when it runs:
(facts query => (produces-suffix [[5 11]]) ;; true query => (produces-suffix [[5 11]] :info)) ;; true
Log level keywords can be useful when debugging tests, as errors will often only appear in the logging output. Currently supported keywords are :off
(the default), :fatal
, :warn
, :info
and :debug
. The log level needs to be the first keyword argument if you supply multiple.
The real power of the 0.4.0
update is the way in which the previous query checkers were defined. Each of the above checkers mimics the behavior of one of Midje's built-in collection checkers with slightly different keyword arguments. This makes sense if you think of a query as a collection of tuples waiting to be produced (by query execution). The above checkers will get you quite a ways, but what if you want to test a query against some other Midje collection checker?
The answer is wrap-checker
. wrap-checker
is a higher-order function that accepts a midje collection checker and wraps it up, turning it into a Cascalog query checker. I'll demonstrate the power of this function by wrapping Midje's has
checker.
has
is a powerful way to run functions across every value in some sequence:
(fact [1 3 5 7 9] => (has every? odd?) ;; true [1 3 5 6] => (has some even?)) ;; true
If you try to use has
against a query it will fail, as it expects to be tested against a sequence, not an unexecuted query. Here's how to get around this:
(defn odd-tuple? [tuple] (odd? (first tuple))) (defn even-tuple? [tuple] (even? (first tuple))) (def has-tuples (wrap-checker has)) (def new-query (let [src [[1] [3] [5]]] (<- [?x] (src ?x)))) (fact new-query => (has-tuples every? odd-tuple?) ;; true new-query =not=> (has-tuples some even-tuple?)) ;; true
has-tuples
will support log-level keywords like any of the predefined query collection checkers.
A few more examples:
(defn id-query [src] (<- [?x] (src ?x))) (let [one-of-tuples (wrap-checker one-of) two-of-tuples (wrap-checker two-of) src [[1] [3] [4]]] (facts src => (two-of odd-tuple?) ;; true src => (one-of even-tuple?) ;; true (id-query src) => (two-of-tuples odd-tuple?) ;; true (id-query src) => (one-of-tuples even-tuple?))) ;; true
All of the collection checkers discussed above can be used with the fact?<-

are also compatible with all of Midje's unwrapped collection checkers, as discussed here.
Midje is an astonishingly good testing framework; I'm continually surprised by how well its idioms and conventions satisfy Cascalog's needs. In my next post here I'll go over some of the more subtle details of the wrap-checker
function. For the curious, here's the code.
If you'd like more information or additional features, please add your thoughts to the midje-cascalog github issues page, or let me know in the comments below (or on twitter! I'm @sritchie09.)

fontsize(size)
Sets the current font size. All text() commands following the fontsize() command will be drawn in this font size. Font size is measured in units of points.
The font() command can be called with a numeric value to set the point size.
fill(0.2) font("Helvetica") fontsize(35) text("hello", 10, 50)

IDLE is an alternative Integrated Development Environment for Python. By default, the Python 1.5.2 and later installations install IDLE and a shortcut to start IDLE on your Start menu.
"IDLE" is a twist on the standard IDE acronym and is also named after Eric Idle, one of the sillier members of the Monty Python comedy troupe, but don't tell him.
As we have discussed, many IDE functions are shared between PythonWin and IDLE (or more correctly, stolen from IDLE by PythonWin, with Guido's blessing). So the differences between PythonWin and IDLE have less to do with features and more to do with platforms.
IDLE runs on almost all platforms that support Python. Although the user interface it provides isn't quite as slick as PythonWin's, you do have an IDE that runs places other than Windows. For many people, this is the single killer feature!
Of course, your choice of environment is up to you, but it appears that people who use Python on multiple platforms prefer IDLE because their environment can follow them. People who use Python only on Windows typically prefer PythonWin and its interface. As IDLE evolves further and the Tkinter GUI framework offers more features on Windows, we may find this simple distinction blurring. We recommend you spend time with both IDE environments and choose for yourself.
IDLE is itself written in Python, using Tkinter, Python's de facto cross-platform GUI package based on Tcl/Tk. Because Python and Tcl/Tk are cross platform, so is IDLE; it works as well on Windows (95, 98, NT) as on Unix (including Linux), with minor, unavoidable differences because of inherent differences between the platforms. It also works on Macintosh (although occasionally you may experience a slight problem, because this platform gets less testing).
This section describes IDLE Version 0.5, which hasn't been released at the time of writing. The Python 1.5.2 distribution comes with IDLE Version 0.4, which differs in a number of details, so these will be detailed where appropriate. In any case, IDLE requires Python 1.5.2 or later to run. Tcl/Tk 8.0 or later (optionally installed with Python 1.5.2) is needed.
As the version number should imply, IDLE is still a young application, and features are developing at a great rate. Check the online documentation regularly to keep up with the current feature set.
When IDLE starts, it presents its shell window. This window is equivalent to PythonWin's Interactive Window or the interactive Python session, and it's where you enter arbitrary Python commands.
By now, you should be completely familiar with Python's own interactive (command-line) mode. We first discussed this in Chapter 2, and also previously in this chapter, so you already know how to use IDLE's Python shell window! Figure 4.5 shows the Python shell window with a few interactive commands.
Since we made a big song-and-dance about the cross-platform capabilities of IDLE, Figure 4.6 shows the Python shell window running on a Unix system. You will probably notice some subtle differences between the two windows; the fonts are different, hence the slightly different window sizes: the default is 80 × 24 character cells on all platforms. You may also notice that on Windows the Help menu is placed next to the other menus, while on Unix it's placed to the far right of the menu bar.
One of the first things the astute reader might query is the lack of the ... prompt in multiline statements. Using the "official" interactive Python mode or PythonWin, multiline statements normally look like:
>>> while x < 10: ... x = x + 1 ... print x, x**3 ... >>>
IDLE takes a different approach. Instead of showing secondary prompts, Python automatically indents these lines with whitespace, just like the regular editor. This is one feature not provided by PythonWin; although the interactive window does perform some smart indentation, it doesn't offer the full-blown smart indentation used by IDLE and the PythonWin editor.
Just like PythonWin, you can move to a previous command and press Enter to copy the command to the end of the buffer, ready for subsequent editing and execution. The shell window also provides history capabilities, allowing you to quickly recall next and previous commands, activated by the ALT-N and ALT-P keys, respectively.
You can use IDLE as an ordinary text editor to write Python programs. As discussed previously in this chapter, PythonWin recently adopted many of IDLE's best editor features, so the same, rich, Python-aware editing environment is available in IDLE. It's worth noting that IDLE and PythonWin have different default keyboard bindings, so the same features may be accessed in different ways; check the IDLE menus for the shortcut keys.
IDLE also colors the text of your program according to syntactic categories. For example, strings are displayed in green, so when you forget a string quote, you will probably notice before you run the program. Other editors have this feature, and some support Python's syntax, but not many (not even Emacs) get it right at all times. The inaccuracy can be annoying, especially when you are editing multiline string literals. IDLE boasts that it gets the coloring 100% right, but you wouldn't expect any less from a Python source-code editor written in Python!
IDLE supports a Python path and Python class browser by selecting the appropriate entry from the File menu. These browsers look remarkably similar to the equivalent browsers in PythonWin, which should come as no surprise, as both IDLE and PythonWin use the standard Python module pyclbr to obtain their functionality.
As with PythonWin, IDLE supports the concept of running and importing scripts. To run or import a script, the file must be opened in the text editor and Edit Run Script or Edit Import Module selected.
These features work the same as under PythonWin. Since we have experimented with these functions using PythonWin, we won't bore you with a repeat for IDLE. However, you may still want to open the same sample script used for PythonWin and test the features using IDLE.
If a traceback is printed to the Python shell window, you can move the cursor to one of the error lines and select the Go to file/line option (from the Debug or right-click menus) to open the file.
As you expect of an IDE, IDLE contains a built-in debugger. To use the debugger, it must first be enabled via the Debug Debugger command from the Python shell window. The debugger dialog appears, and the shell window responds with:
[DEBUG ON] >>>
IDLE is now ready to debug. To start the debugger, open the script to debug and run (or import) it. For the purposes of this example, let's debug the same script you used for PythonWin (C:\Scripts\pywindemo.py in the example). Once the file is open, select Edit Run script (or press Ctrl-F5). The debugger dialog becomes active, and the debugging session begins. Figure 4.7 shows you stopped inside your main function.
The stack leading to the current call is shown. Selecting an entry displays the local and global variables and the source code for the stack entry, depending on the options selected at the top of the dialog.
At the time of writing, there are a few limitations in the IDLE debugger worth mentioning:
When debugging the top-level of a module, the Go and Over commands function like the Step command. Go and Over don't function correctly until the top-level script calls a function.
The Python shell window is effectively disabled during the debugging session. You can't use normal Python commands to view and change variables while the debugger is active.
It's quite possible that these and other limitations will be removed by the time you install IDLE.
IDLE supports postmortem debugging, which allows you to capture the state of a Python program after an exception. Unlike PythonWin, where postmortem debugging must be explicitly enabled when running a script, IDLE allows you to perform this analysis at any time directly after an unhandled exception has occurred. To perform postmortem debugging, select Debug Stack Viewer after the traceback has been printed. The debugger dialog is then activated, allowing you to view the state of each stack entry in the traceback.

Let's Build a 3D Engine
Wrinklefree jQuery and HTML5
Wrinklefree JS for Hipsters
- The vision is the drive, the story is the reason, the craft is the talk.
- Back to basics, falling back in love with simple pleasures.
- JavaScript basics were more helpful to me than anything, in the end.
- Math, DOM, and game concepts drive the complexity.
A confession
I'm not really a "graphics guy".
this simple engine,
and I knew I was in for a long fight.
Screenshot tour of Agora
Sometimes a person doesn't need a solution, but rather help seeing the problem.
How do I make a single page app with blah blah feature list?
How do I make my users not hate me?
Tour of rudimentary 3D engine
3D
When the client saw this...
- simplicity > complexity
- cross-platform
- speed
- fun (for them) - delights users
- fun (for me) - delights developer :)
Vanilla JS / Functional Concepts
function bind(fn, context /**, args **/ ) { var args = [].slice.call(arguments); args.splice(0, 2); return function() { fn.apply( context, args.concat([].slice.call(arguments)) ); } }
Vanilla JS / OOP Concepts
function Polygon(id, coordinates, color, opacity, stroke, forceToBackground) { this.id = id; this.coordinates = coordinates; this.color = color; ... } Polygon.prototype.rotate = function() { ... }
Vanilla JS / Event handling
window.addEventListener('resize', function() { rerender(); });
Forward-looking tech with a nod to old-timey practices
var loop = bind(theLoop, renderContext, renderer); var recursiveAnim = function() { loop(); requestAnimationFrame(recursiveAnim); }; requestAnimationFrame(recursiveAnim);
Vanilla JS / memory consumption
function createPolygons(building) { var swa = [ [0, 0, 0], //(x, y, z) ... ]; return [ new Polygon(swa, ...), ... ]; }
- drawing SVG != drawing Canvas != drawing WebGL
- still, all just 2D APIs (e.g. THREE.js is the 3D library)
- Raphael, sorta fast; needed more flexible access to DOM
- DOM elements -> DOM events and DOM APIs
- browsers draw SVG fast, math and memory = bottlenecks
Raphael, simple at first
var paper = Raphael(10, 50, 320, 200); var circle = paper.circle(50, 40, 10); circle.attr("fill", "#f00"); circle.attr("stroke", "#fff");
<svg version="1.1"> <polygon style="fill:rgb(43,244,113);" points="241,367 241,551 84,459 84,367 136,243 241,367"> </polygon> </svg>
- IE9+
- Just a bunch of paths → [(x1,y1), (x2,y2), (x3,y3), ...]
- Can modify/persist the <polygon> elements with basic DOM apis
- projections (convert 3D coordinates to 2D pixels)
f(x,y,z) → (x,y)
function project(point, camera, w, h, fov) { var minDim = w - h < 0 ? w : h; var s = minDim / fov, z = point[2] + camera[2], x = (w/2 + scale * (point[0] + camera[0]) / z), y = (h/2 + scale * (point[1] + camera[1]) / z); return [x,y]; }
Now do that for every point, in every polygon.
function paint(shapes, svgShapes, camera, width, height, fov) { for (var i = 0, len = shapes.length; i < len; i++) { for (var j = 0; j < num_coords; j++) { point = project(coords[j], camera, width, height, fov); point && (svgPoints += " " + point[0] + "," + point[1]); } svgShapes[shape.id].setAttribute("points", svgPoints); } }
- data and event setup
- get projections
- draw()
- repeat with rAF -> "das loop"
Lessons learned
Awesome experiences < Mediocre software
I'd rather build one superb app over five normal ones.
When I tell someone that I did this from scratch...
I know it's crazy I started from scratch, but...
- Everything works exactly how I designed it to, and the bugs are easy to find.
- No mysteries, shallow stack traces.
- It's fun to make a new release every week.
So
Takeaways?
- Native JS APIs are easier than you think
- The Math is just a lot of steps
- Graphics frameworks share common features, and aren't that magical
- Minimalism and modularism is beautiful
- Speed should be a requirement, not just a feature


2 Samuel 11:19
And charged the messenger, saying, When thou hast made an end of telling the matters of the war unto the king,


During my senior year of college I took a computer science course and it immediatly sparked my interest. After that class I had a plan to finish my undergrad career in biology while studying web development on the side. I studied how to create web pages using html, css, and bootstrap while incorporating different functionalites using javascript. Eventhough I learned a great deal on my own,however a proper education was essential for a career in full stack development.
Now at Rutgers universirty I am becoming an all around, versatile developer with both front and back end skills(especially MEAN stack). Every day I am excited to learn a new skill whether its dealing with SQL, node.js, or even learning a simple jquery command that will help me navigate through the DOM. There is a lot of room for creativity and growth in this field and I am excited to keep learning.
