Dynatree is a dynamic JavaScript tree view control with support for checkboxes, drag'n'drop, and lazy loading.
Main features:
Dynatree runs best, when the HTML document is rendered in a strict mode like
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
.
Avoid the quirks mode.
You can download the current dynatree package at
http://code.google.com/p/dynatree/downloads.
It contains everything needed including the source, some documentation and examples.
jQuery is already included, but you can check the jQuery site
for the latest versions of jquery.js and ui.core.js.
This documentation contains script examples and links.
See also the Example Browser for some more advanced live demos.
Using the [View source code]
link in the
Example Browser is probably the best way to learn about Dynatree.
Let's start with a simple example:
      <link rel='stylesheet' type='text/css' href='skin/ui.dynatree.css'>

As an alternative, it is possible to leave away the children
option and
add a
 inside the
 tag instead.
See Initializing the tree structure from a
 element for an example.
I am going into more details in the following sections.
Dynatree is based on and made for jQuery. If you are not familiar with this, you might also want to check the jQuery documentation.
The tree is initialized in the onload event of the html document. In jQuery this is usually done by passing a function to $(..) :

The dynatree widget is then attached to an empty
 element with a given ID of 'tree'.
This id can have any value, it only has to match the jQuery selector, in our case '#tree'.
Options are passed to the dynatree() function as a dictionary in curly braces:
$("#tree").dynatree({ […] });
Tree options are passed as plain JavaScript objects in curly braces, e.g.
{ … }
.
The following script shows the available options.
All options have a reasonable default, so we may only have to pass the onActivate
handler.
$("#tree").dynatree({ title: "Dynatree", // Tree's name (only used for debug outpu) minExpandLevel: 1, // 1: root node is not collapsible imagePath: null, // Path to a folder containing icons. Defaults to 'skin/' subdirectory. children: null, // Init tree structure from this object array. initId: null, // Init tree structure from a

A tree structure is made of nodes. Every node may in turn contain
a list child nodes.
A dynatree always has exactly one root node, and all top level nodes
of our tree are created as direct descendants.
The root node is usually hidden, so we only see the nodes that we have added.
Dynatree can read it's structure from different sources:
children
option is passed, it will be used.
initAjax
option is passed, it will be used.
initId
option is passed, it will be used.
Methods 1-3 expect a list of node options, as described in the following sections.
Node options are defined as plain JavaScript objects in curly braces, e.g.
{ … }
.
Most of the time we pass a list of node options like this
children: [ { … }, { … }, … ]
.
The follwing snippet shows the attributes that can be used to define a tree node.
There are reasonable default values for all options, so we may only have to pass a title
.
children: [ { title: null, // (required) Displayed name of the node (html is allowed here) key: null, // May be used with activate(), select(), find(), ... isFolder: false, // Use a folder icon. Also the node is expandable but not selectable. isLazy: false, // Call onLazyRead(), when the node is expanded for the first time to allow for delayed creation of children. tooltip: null, // Show this popup text. href: null, // Added to the generated  tag. icon: null, // Use a custom image (filename relative to tree.options.imagePath). 'null' for default icon, 'false' for no icon. addClass: null, // Class name added to the node's span tag. noLink: false, // Use  instead of  tag for this node activate: false, // Initial active status. focus: false, // Initial focused status. expand: false, // Initial expanded status. select: false, // Initial selected status. hideCheckbox: false, // Suppress checkbox display for this node. unselectable: false, // Prevent selection. // The following attributes are only valid if passed to some functions: children: null // Array of child nodes. // NOTE: we can also add custom attributes here. // This may then also be used in the onActivate(), onSelect() or onLazyTree() callbacks. }, […] ]
The node options are also passed to the event handlers and can be accessed like this:
onActivate: function(node) { alert("You activated " + node.data.title); },
Details:
{ title: "Pretty node", addClass: "customClass1" }or

Pretty nodecan be styled using css as
span.customClass1 a { background-color: maroon; color: yellow; }

To override the node attribute defaults, modify the structure before initializing dynatree:
  <link rel='stylesheet' type='text/css' href='skin/ui.dynatree.css' >

item1 with key and tooltip
item2: selected on init
Folder with some children

Sub-item 3.1
Sub-item 3.2

Document with some children (expanded on init)

Sub-item 4.1
Sub-item 4.2

Lazy folder

Finally, it is always possible to program the DynaTree and DynaTreeNode objects directly.
See also Programming dynatree.
$(function(){ // Initialize the tree in the onload event $("#tree").dynatree({ onActivate: function(node) { alert("You activated " + node); } }); // Now get the root node object var rootNode = $("#tree").dynatree("getRoot"); // Call the DynaTreeNode.addChild() member function and pass options for the new node var childNode = rootNode.addChild({ title: "Child node 1", tooltip: "This child node was added programmatically.", isFolder: true }); // childNode.addChild({ title: "Document using a custom icon", icon: "customdoc1.gif" }); });
When a user clicks a node, we want to react in some way.
So at least we want to implement an onActivate
handler.
All event handlers are passed an instance of DynaTreeNode as argument.

The node options can be accessed like this:
onActivate: function(node) { alert("You activated " + node.data.title); },

The following example handles an activation event by opening a url in a new window.
This assumes, that we have defined an additional custom attribute named
'url' in the node options, like so:

jQuery home
jQuery docs
or
children: [ { title: "jQuery home", url: "http://jquery.com" }, { title: "jQuery docs", url: "http://docs.jquery.com" },
Also, the title of the currently active node is displayed in the  tag.
$("#tree").dynatree({ […] onActivate: function(node) { if( node.data.url ) window.open(node.data.url); $("#echoActive").text(node.data.title); }, onDeactivate: function(node) { $("#echoActive").text("-"); }, […] });
The following example writes the title of the currently focused node to the  element:
$("#tree").dynatree({ […] onSelect: function(flag, node) { if( ! flag ) alert("You deselected node with title " + node.data.title); var selectedNodes = node.tree.getSelectedNodes(); var selectedKeys = $.map(selectedNodes, function(node){ return node.data.key; }); alert("Selected keys: " + selectedKeys.join(", ")); }, […] });
If we use the cursor keys to walk the tree nodes, the focus changes to the next node, but the active node remains the same unless we use [Space] or [Enter].
Also, when we click on a folder node it is only focused, but not activated.
The following example writes the title of the currently focused node to the  element:
$("#tree").dynatree({ […] onFocus: function(node) { $("#echoFocused").text(node.data.title); }, onBlur: function(node) { $("#echoFocused").text("-"); }, […] });
Dynatree supports delayed loading of tree nodes, which means we read the child nodes only when their parent is expanded.
Because the data request is performed asynchronously, the browser will not block and is still responsive. Dynatree will display a spinning wheel, while waiting for the request to complete.
To make this happen, we have to
isLazy
option to true.
onLazyRead
callback to send an Ajax request,
create the child nodes, and set the 'ok' status.
$("#tree").dynatree({ […] onLazyRead: function(node){ node.appendAjax({url: "/sendData", data: {"key": node.data.key, // Optional url arguments "mode": "all" } }); }, […] });
Typically we would implement onLazyRead
by calling the
node.appendAjax()
function.
It expects one option object argument, as described in the documentation for
the jQuery.ajax() command.
These options are set by default:
cache: false
and dataType: "json"
.
Note that the success
and error
options
are implemented differently from the jQuery standard:
They pass different arguments and are called after the
Dynatree default processing took place.
This makes it easy to use the success
callback to apply any
custom postprocessing, for example activating a node or binding events.
$("#tree").dynatree({ […] onLazyRead: function(node){ node.appendAjax({url: "/sendData", data: {"key": node.data.key, // Optional url arguments "mode": "all" }, // (Optional) use JSONP to allow cross-site-requests // (must be supported by the server): // dataType: "jsonp", success: function(node) { // Called after nodes have been created and the waiting icon was removed. // 'this' is the options for this Ajax request }, error: function(node, XMLHttpRequest, textStatus, errorThrown) { // Called on error, after error icon was created. }, cache: false // Append random '_' argument to url to prevent caching. }); }, […] });
The web service is expected to return a valid JSON
node list, formatted like this:
[ { "title": "Node1", "isLazy": true, "key": "BC13B21636CD6D5C", … }, { … }, … ]
See Node options for a list of supported attributes.
When the response was received, appendAjax()
appends the child
nodes and calls node.setLazyNodeStatus(DTNodeStatus_Ok)
to
remove the wait icon.
Note that initAjax
is simply a special case, where the tree's
root node is loaded on startup.
See Initializing the structure from an Ajax response
for a sample to initialize the whole tree with an Ajax request.
This sample code (written in Python) shows how a server could create a response:
# Build node list as JSON formatted string: res = '[' res += '{ "title": "Node 1", "key": "k1", "isLazy": true },' res += '{ "title": "Node 2", "key": "k2", "isLazy": true },' res += '{ "title": "Node 3", "key": "k3", "isLazy": true }' # no trailing "," at the last line res += ']' # Add support for the JSONP protocol: # This means, if the request URL contains an argument '?callback=xxx', # wrap the result as 'xxx(result)' if "callback" in argDict: res = argDict["callback"] + "(" + res + ")" # Make sure, content type is JSON: start_response("200 OK", [("Content-Type", "application/json")]) # Return result (the square brackets are Python / WSGI specific): return [ res ]
See dynatree_server.py for a sample
implementation of a web server that handles this (~150 lines of Python code).
When this server is running, you can try this live example
of a lazy tree.
If we need more control, or if the server cannot provide JSON in Dynatree's
native format, we could also use jQuery.ajax()
to fetch the data, then transform it and call node.addChild()
:
$("#tree").dynatree({ […] onLazyRead: function(node){ $.ajax({ url: […], success: function(data, textStatus){ // In this sample we assume that the server returns JSON like // { "status": "...", "result": [ {...}, {...}, ...]} if(data.status == "ok"){ // Convert the response to a native Dynatree JavaScipt object. var list = data.result; res = []; for(var i=0, l=list.length; i<l; i++){ var e = list[i]; res.push({title: "" + i + ": " + e.fcurr + "-" + e.tcurr + ":" + e.ukurs, icon: false}); } // PWS status OK node.setLazyNodeStatus(DTNodeStatus_Ok); node.addChild(res); }else{ // Server returned an error condition: set node status accordingly node.setLazyNodeStatus(DTNodeStatus_Error, { tooltip: data.faultDetails, info: data.faultString }); } } }); […] });
Drag and drop functionality is enabled by defining the appropriate callbacks:
$("#tree").dynatree({ [...] dnd: { onDragStart: function(node) { /** This function MUST be defined to enable dragging for the tree. * Return false to cancel dragging of node. */ logMsg("tree.onDragStart(%o)", node); return true; }, onDrop: function(node, sourceNode, hitMode, ui, draggable) { /** This function MUST be defined to enable dropping of items on * the tree. */ logMsg("tree.onDrop(%o, %o, %s)", node, sourceNode, hitMode); sourceNode.move(node, hitMode); } } });
There are a lot more callbacks that can be used to fine tune the behaviour. Check the source code in the samples in the Example Browser to learn more.
When initializing a tree in persist mode, we first check, if persistence
cookies already exist.
If not, we assume first-time initializing, read the status from the tree source,
and store it into new cookies.
Otherwise we assume re-loading, ignore the source node attributes and override them using the cookie info.
In either case, the 'active', 'expand' and 'select' status of a node is read from
the data or restored from the cookies.
However, no onQueryActivate, onActivate, onExpand, onSelect, etc. events are fired.
(The only event that may be fired is onFocus.)
In order to generate these events on reload, we may use the callback function onPostInit()
and tree.reactivate().
$("#tree").dynatree({ […] onPostInit: function(isReloading, isError) { // 'this' is the current tree // isReloading is true, if status was read from existing cookies // isError is only used in Ajax mode // Fire an onActivate() event for the currently active node this.reactivate(); }, onActivate: function(node) { // Use status functions to find out about the calling context var isInitializing = node.tree.isInitializing(); // Tree loading phase var isReloading = node.tree.isReloading(); // Loading phase, and reading status from cookies var isUserEvent = node.tree.isUserEvent(); // Event was triggered by mouse or keyboard $("#echoActive").text(node.data.title); },
The problem with restoring the status of a lazy tree is, that the currently active or selected nodes may not be part of the tree, when it is freshly re-loaded.
The basic idea is to leave it up to the backend web service to deliver not only the top-level nodes, but also all nodes that are required to display the current status.
For example, it may be neccessary to render 3 parent nodes, if the active node is at level # 4.
The backend may also deliver all child nodes of expanded parents.
Or in selectMode 3 (hierarchical) we may want to send all nodes, that are partly selected.
initAjax (and appendAjax) have 3 options, that make it easy to pass persistence information to the web service.
See dynatree_server.py for a sample
implementation of a web server that handles this (~150 lines of Python code).
When this server is running, you can try this live example
of a lazy tree.
$("#tree").dynatree({ […] initAjax: {url: "/ajaxTree", data: {key: key, mode: mode, filter: filter }, addActiveKey: true, // add &activeKey= parameter to URL addFocusedKey: true, // add &focusedKey= parameter to URL addExpandedKeyList: true // add &expandedKeyList= parameter to URL }, onPostInit: function(isReloading, isError) { // In lazy mode, this will be called *after* the initAjax request returned. // 'this' is the current tree // isReloading is set, if status was read from existing cookies // isError is set, if Ajax failed // Fire an onActivate() event for the currently active node this.reactivate(); }, onActivate: function(node) { // Use status functions to find out about the calling context var isUserEvent = node.tree.isUserEvent(); // Event was triggered by mouse or keyboard $("#echoActive").text(node.data.title); },
The dynatree widget provides a set of plugin methods, that can be called
directly.
For example
$("#tree").dynatree("disable");
However this plugin implementation is based on a class called DynaTree
that holds a set of DynaTreeNode
objects.
These classes expose methods that can be accessed for enhanced functionality.
For example:
// Get the DynaTree object instance: var tree = $("#tree").dynatree("getTree"); // Use it's class methods: tree.activateKey("key1234"); // Get a DynaTreeNode object instance: var node = tree.getNodeByKey("key7654"); var rootNode = $("#tree").dynatree("getRoot"); // and use it node.toggleExpand();
Besides the constructor, that is called like this:
$("#tree").dynatree({ […] });
The following methods are globally available from the ui.dynatree namespace:
$("#tree a").hover(function(){ var node = $.ui.dynatree.getNode(this); logMsg("Hover in %s", node); }, function(){ [...] });
The following methods are directly available from the plugin:
$("#tree").dynatree("option", "autoCollapse", true); $("#tree").dynatree("option", "fx", { height: "toggle", duration: 200 });

Note: instead of passing a single child object, we could also pass an array
of such objects.
Also, the children may again contain children
attributes, thus
defining a sub tree.

The tree's fonts, colors, and icons are defined using CSS, so changing the appearance is simply a matter of including a custom stylesheet or by replacing icons.gif with another version.
    <link href="../src/skin-vista/ui.dynatree.css" rel="stylesheet" type="text/css">  <link href="skin-custom/custom.css" rel="stylesheet" type="text/css" >
Custom.css would include lines like this:
.dynatree-has-children span.dynatree-icon { background-position: 0 0; background-image: url("doc_with_children.gif"); }
Changing the appearance and icons of single nodes is done by assigning a custom class:

Document with custom class
or
children: [ { title: "Document with custom class", addClass: "custom1" },
we would then add CSS definitions for the new node to our stylesheet:
span.custom1 a { background-color: #ffffbb; color: maroon; } span.custom1 span.dynatree-icon { background-position: 0 0; background-image: url("customDoc2.gif"); }
Strings can be translated in the tree options:
$("#tree").dynatree({ […] strings: { loading: "Daten werden geladen…", loadError: "Fehler beim Laden!" }, });

Thomas Inglis, 23, from Portland Road in Hucknall was sentenced on Wednesday, December 4 at Nottingham Crown Court.
He has been ordered to sign the sex offenders' register for life and was given a Sexual Harm Prevention Order for 10 years.
He was arrested on October 10 by officers from the public protection department.
Officers from the neighbourhood search unit seized a number of items including a written note, an iPhone and a laptop.

"This sentence shows that officers across Nottinghamshire will use a variety of tactics to identify and bring to justice those who seek to abuse children.
"The message to those people is clear. The internet is not a lawless playground where they can seek to live out their illegal activities.
"Police officers are working hard 24/7, online and offline, to identify and bring to justice sex offenders like Inglis, and above all to help keep children safe."

First time I browsed the web
I was fourth grade and received an assignment to write a paper on our national poet. Until then there was quite a rule on only using books and going to the almost inexistent library for school work. A classmate who made a comprehensive paper told me she found the info on Google. So I go home and tell my parents to let me use the internet for school It was frustrating because it is about a Romanian poet, and the information is scarce so it was hard to find what I was looking for. Furthermore, I always found the modem to be incredibly unaesthetic. I never shared that thought though because I thought the benefit of having internet access outweighed the visual handicap.
Early impact of the internet
I considerably improved my English by reading tech and science articles on Yahoo starting with the age of 10-11. I read more than a handful a day and remember at that time I wanted to design devices myself.

First time I browsed the web
I'd loved computers for a long time, ever since I was introduced to them in grade school. Classrooms had old Macs in them where you could do dot-matrix printing and play Oregon Trail. We used them to draw and to learn. I stayed fascinated for years, but it was one day when I was 12 years old that my neighbor friend told me they got the internet. I had heard about the internet, that it connected you to information and that you could find pages about anything you could think of. I called him up and asked if I could come over. When I got there we ran straight upstairs to the office and sat down. He connected and the modem made all its weird sounds and then he opened up Netscape and I watched the first webpage load in slowly. Yahoo. There was the funny logo with the exclamation point. The list of blue links. There were categories for all kinds of things. We spent the next 4 hours clicking from category to category and from page to page, seeing what kinds of wild sites we could find. That evening I started my campaign of annoying my parents to death to get a computer for our home and it had to be one that could connect to the internet.

The first time I actually felt the internet was impactful
So the first time I actually felt the internet was impactful of my life was back in the day was, before school introduced us to a computer showing us how to do reading AR test and some history games but it didn't mean much to me. So one day my friend comes to my house and he shows me a game called Runescape back in 2008 and I was curious to see what the game was. It was an MMORPG that opened the world to me to online chatting, gaming, sense of achievement when leveling or powering up my character and even meeting new friends. With that I was hooked then later he showed me how youtube was and how I could stream online videos on youtube. After some time I was so into Runescape I downloaded a Hypercam 2 screen recorder and started filming my youtube tutorials for power-up in the games and downloading video software to edit the video and uploading it , later I found private servers and I downloaded one and started to edit the code to make me owner of the server and that's how I got into coding. Also from the MMORPG genre started to introduce me to other games like WOW and later future games and new communities of people I have met online, youtube as well with the videos and then looking up coding tutorials and other places to grab information.

My first experience using the internet
My first experience using the internet is most likely a relatable one.
I was in school, in Paris, and the teacher brought the entire class up
to the computer room. I can't remember if the computers were just
installed or if it was just the first time we where allowed to use
them but I do recall that one particular student had some previous
knowledge, mainly due to the fact that he knew how to bypass the
school block and was able to get us straight to the most exciting
games website. I remember the walls were orange but I have not the
recollection of the computer we where using or what we were supposed
to be doing (most likely something less exciting like WolframAlpha or
paint). Once we got onto the games website I was blown away by the
number of games I could play at my will, it was like an endless supply
of fun to me and I was incredibly excited. It was clear at that moment
that I had underestimated the internet.
My mother had a Mac in the house which she mainly used to write, and
I'm sure we had an internet connection at that time but I had never
tried using it. To me, the computer was just a tool for work and there
was nothing cool or desirable about that, I had no interest in them
whatsoever. This obviously changed when I found all the games.
Shooting aliens or just simple platformers… I was hooked.
So that's my first real memory of using one and being excited by one.
First, the thrill of being able to bypass the school block on
forbidden websites then finding out that there where entire websites
filled with thousands of games, my mind was blown.

I'm not sure if this was the first time
I'm not sure if this was the first time I interacted with the web but what I do remember was email using AOL. My brother and I were still really young (around 6) and we would draw a lot. My father lived in Switzerland while we were in Germany, so we often would fax our drawings. But that meant that my father always saw them in greyscale. Then we got an email account where we could scan and send our drawings to my father. He finally got to see them in color and we could respond to our "artwork". I remember being amazed by this and we were always very excited to check our email to see any comments (Mum always supervised us, she wasn't very trusting of the web!)

I thought you can instal your internet
To be honest I don't remember the first time I used the internet
because as I remember it always was there. Though, I remember some
funny stories about how I was learning to understand what is it and
how it works. So I am going to write about one of them.
As I already mentioned, the Internet was existing since I was born,
and when I was 5 years old I remember that my family had one super old
computer, which looked like a big plastic box, and a more new version
of computer, which was already quite flat. Everyone, of course, was
using the new one because it was faster and better, and I, as the
smallest person in the family was left to play with an old one.
Apparently, the new computer was connected to the internet and I was
observing my parents searching web, so I knew everything about how it
looked inside and how to use it. Well, at least I thought that I knew
everything. And one day, playing around the old computer I found the
icon of Internet Explorer and I was sure that this icon means that I
can access the internet. And being very excited about my discovery I
decided to search for something. When I clicked on it nothing happened
because the computer was not connected to any network but for a moment
I thought that I broke something in the computer because I was
thinking that you can install the "Internet" on your computer like all
the other programs. I came to my parents with this story and they
explained to me that the internet is not just one program.

I believe my first interaction with the web was in my father's office
To be honest I don't remember the first time I used the internet
because as I remember it always was there. Though, I remember some
funny stories about how I was learning to understand what is it and
how it works. So I am going to write about one of them.
I believe my first interaction with the web was in my father's office
when they first installed a computer with windows95. I believe when
the browser opened it was empty and then we would go to websites like
sina.com ,
yahoo.com or
sohu.com , which
were the main digital publisher at the time (of course I had no idea
what "digital publisher" meant at the time). I remember the "minimize"
and "close" button on the top left (or right?) Was quite confusing,
and my father was freaked out when he saw the window disappeared after
I clicked on "_". He would think I "broke" the computer.
It was all text on the webpage, sight a few images, which we would
click with the mouse to get to the content. It was kind of like
reading newspapers and magazines, just with a bit more contents. The
navigation was a bit confusing (or computers in general), that we
would close the browser and reopen it to get to the content on the
same website if we were "lost" and couldn't find our way back to the
main page. Back button, refresh button were magic to us and we were so
scared just to use them too often, feeling it was like reusing a
physical object which would eventually wear out and the computer will
break down.
Internet Explorer was, of course, the only way of browsing. The blue
"e" icon was like a window to the world, center of the action, which
magic happens when double clicked on.

I don't remember any remarkable first interactions with the web
I don't remember any remarkable first interactions with the web, but I remember a time in my childhood where it was all about Bluetooth. We exchanged ringtones, cool background pictures, etc. I always got so frustrated when my Bluetooth didn't work, which was almost always. But I got such joy when it worked and I could use this new ringtone as my own as well or the new background wallpaper or just listen to the song that I received. This feeling of being able to share something with your friends was so amazing at the time. Most of the things I did on a computer were offline in the beginning as far as I can remember.

I got my first computer in 2005
I got my first computer in 2005. Operation System was Windows XP but the internet very very low speed. Was called Dial-Up modem which made creepy sounds and if someone calling, the internet immediately shot down) After one year, finally we have wi-fi router. One friend told me Microsoft introduced a new operation system Windows 7. I looked in Microsoft website (and yes it was my first web site) and I saw that Microsoft offers to download a new Windows Media Player free. It took me almost 4 hours to get the .exe file. When I installed NEW WMP. That was a very different design from Windows XP and I liked it. At that moment I realized that web it's powerful "tool".

I can remember quite well the first time that I used the web
I can remember quite well the first time that I used the web since I
was actually waiting for finally "getting installed the internet" on
my computer.
It was in 2000 and I had to dial in via a modem (I'm old enough to
remember the pre-flat rate time) and I couldn't wait to create an
E-Mail account for being able to send my very first E-Mail to the only
other one of my classmates that had Internet already at this time.
Funnily this new way of communication & connecting people that the
Internet provided was the most exciting purpose for me and shortly
after we discovered the world of chatrooms and were totally amazed of
the possibility to talk to people somewhere in real-time.

I WAS BORN, BUT... (UMARETE WA MITA KEREDO) (director/writer: Yasujiro Ozu; screenwriters: Akira Fushimi/Geibei Ibushiya; cinematographer: Hideo Mohara; cast: Hideo Sugawara (Older Son), Tokkan Kozo (Younger Son), Tomio Aoki (Keiji), Tatsuo Saito (Yoshii), Mitsuko Yoshikawa (Yoshi's Wife), Takeshi Sakamoto (Iwasaki), Teruyo Hayami (Mrs. Iwasaki), Seiichi Kato (Taro), Shoichi Kojufita (Delivery boy), Seiji Nishimura (Schoolmaster), 1932-Jap.)
Reviewed by Dennis Schwartz
The Shochiku Kamata studio specialized in nonsense comedies, something the great director, one of the world's most acclaimed, Yasujiro Ozu (The Tokyo Story/Late Spring/Floating Weeds) was keen on doing during this period of his film career, when he refused to make talkies until yielding in 1935, but continued to make silent social comedies, somewhat in the style and equal to in quality to the Charlie Chaplin and Buster Keaton films, though Ozu's films were seen through the eyes of children rather than taken from the adult's point of view.  In I WAS BORN , BUT..., a film with lots of sight-gags, made as a social comedy turning darker as the story got a bit more involved with the patriarch of the family, Mr. Yoshii (Tatsuo Saito). This splendid example of a salaryman's film, is the first great film of the master's, with many others to follow. It is a film about the lower-middle-class (shomin-geki) and it takes the form of a domestic drama, something Ozu continued turning out for his entire film career, which spanned from 1927-1963. This life-long bachelor, ironically making family dramas, passed away at the early age of 60.
The depression came to Japan in 1927 and continued into the 1930s. By 1932, one out of five unemployed workers was a salaryman, as the banking system crashed. Haunted by the fear of unemployment, the Japanese worker was a subservient figure, something that Ozu uses in this film to exploit his comedy and satire of the human condition and comment on the pecking order of society, where the rich remain in power, no matter what.
The Yoshii family moves to the Tokyo suburbs, which places the lowly clerk near the residence of his boss, Mr. Iwasaki (Takeshi Sakamoto), which draws comments from Yoshii's fellow clerks how he moved there to ingratiate himself further with the boss. The two Yoshii sons, the ten year old (Hideo Sugawara) and the eight year old (Tokkan Kozo) have a tough time fitting in with the other kids in the neighborhood, who pick on these newcomers. Among the group is the boss's son, Taro (Kato) and the big bully of the group, Keiji (Aoki). There is a comic sandal fight among the boys, which brings out the film's visual humor from the way the framing of the shots magnifies the synchronized reactions of the two fighters. The bully takes away the puzzle-ring from the little brother, but is baffled how to work it. The group scares the brothers so much, that on the first day of school for the new students, they play hooky.  But they do not feel capable of imitating how a teacher makes an "E", so they get a parked beer-delivery truck's young adult driver to forge the grade. He slyly puts an "F" there and smiles as he leaves the students unaware of what he did. Before arriving home, the father runs into the older boy's teacher, who acts concerned why the children didn't show up for school.  The boys are not satisfied with this answer, but still look up to their father. In fact, Ozu's camera angles for adults when talking to children, are always taken from a higher elevation so that the adults are talking down to the children, always in a position of superiority.
The older brother is the braver and more cunning one, and when he is again confronted by the hostile boys, he realizes that today is payday for his father and his mother (Mitsuko) can afford to buy some beer for her husband. He tells the delivery man about this, who becomes very pleased with the boys after the boys' mother bought six bottles of beer from him. So when the older brother asks him as a favor to them, if he can beat up the bully, he obliges them, sending the bully home crying. But when he is asked to also beat up the boss's son, he tells them, no. His family buys more beer than yours.
The boys when they return to school the next day, under the watchful gaze of their father, find themselves being accepted by the group. Ozu draws the analogy of the workplace power structure to the way children naturally socialize, and states that the adults power is vindictively social, derived from one's station in life and how much money one has. Later on, the children are seen playing games together and the brothers prove to be good at also being bullies and are telling the other children that their father is greater than anyone else's. The game they play is a mock power game of killing, by giving one the evil eye and the other falls down pretending to be dead. They also comically cross themselves in a parody of Christian ritual. But when Yoshii comes on the scene and sees Taro lying on the ground, he quickly picks him up and brushes him off, to the disappointment of the boys.
The question of submission becomes the motif of the film, as Yoshii is seen by the boys bowing to Taro's father, and they don't understand this. For them, Taro is not as smart or as strong as they are, so why should their father submit to his father if he is the greater man.
That Yoshii was an inferior man was made clear to the adults in the audience from the first scene on, where he is humiliated that his truck got stuck in the mud and the boys have to push him out. And that before he even gets settled into his new house, he runs over to his boss' house and kowtows to him.
The film shifts gears and the comedy now becomes dark, as Yoshii is at the boss' house watching home movies and the boys are also there as guests of Taro, and what they see results in their loss of innocence. The home movies become unbearably embarrassing to watch for Yoshii and the children, as Yoshii acts the part of the clown in them and is seen as an obviously inferior man than his boss. He is seen looking up to the boss all the time and performing in order to please the boss. Yoshii, himself, is embarrassed that he has to lower himself so much, but he is secretly pleased that he is so successful as a clown and can make everybody laugh. In the house, while watching the movie, he is doing what he did on film, rushing to light the boss's cigarette and trying to ingratiate himself to the boss in anyway he can. Taro's only comment is, your father is really funny. But the boys can't take being in the same room with their father anymore and run out of the house. Ozu' other purpose of showing the home film, being always the gagman, it also gives him a chance to parody his own way of shooting films by having the home movie filmed in the same style he uses for this movie, such as by using the same tracking shots and camera height angles. He even has some of the boss's other guests yawning at parts of the movie where he shows boats and cars.
Back in the house, the boys throw a tantrum, as they react to their father's answers to their constant barrage of questions they hurl at him. Asking him, why does he bow to the boss? The wry salaryman responds, "If I didn't, I wouldn't get paid and you wouldn't eat." Ozu's implications are clearly centered around the social use of power, comparing the boys rise in stature into the neighborhood group of boys, as being determined by who is tougher and smarter. The boys illusion is that all power can be won through one's talents. But in the business world, the boss doesn't have to possess those character traits, he is the boss because that is the way society is structured, and it pays to submit to that hierarchy or else you will be left out in the cold to fend for yourself.
 Here, the mother takes over the next day and cooks up some delicious looking rice cakes for the boys to eat, which they eventually will, and their father casually joins them, and there are no more pretences about who he is, as they eat and talk in a natural manner. When the father encourages them to keep going to school, to try to become great people, he also asks the younger one what he wants to become, and he says, "A lieutenant general." The father then says, "Why not a general?" And he responds, "Because my brother will be the general." And things seem to be back in order, everyone knows their place in life and the sham of the father having to be regarded as a great person is no longer carried out. The relationship is now an honest one after the healing process is completed. The "but" in the film's title comes into place, as it indicates that everyone is born equal, "but" that changes soon enough. There is always something to disturb the stability assumed from the outset. Ozu affirms the necessity of the family sticking together to face these social challenges as the best chance everyone has of making it successfully through life.
The only time we see the father and mother talking seriously together, is after the children throw their tantrum, and she tells the disconsolate husband, I hope the boys have a better life than we did, and he takes out a bottle of whiskey, prepared to drown out his shame and low conception of himself with forgetfulness, as he pragmatically responds, "They'll have to live with it all their lives." When he and his wife check in on the sleeping brothers, they ask aloud, "Will they lead the same kind of miserable lives we have?" It is now clear that Yoshii grovels because he can't do anything else about it. And like many parents in America, he only wishes his children have a better life than he does, which draws him closer to the audience and presents him in a more sympathetic light.
In the closing scene, after the reconciliation is made among the boys and the father, the boys tell Taro that his father is the greatest and now encourage their father to bow to Taro's father. And to further emphasize the pecking order that exists and is realized by the no longer innocent boys, the bully rushes down the street to make sure the teacher sees him doff his cap. The plot of the film is encompassed within a short five-day period, and it parallels in a didactic way the social structure of the children and the grownups, and how in each group adjustments have to be made in order to survive, with the majority of the film being concerned about how the boys start growing up. The adult world is mainly used as a expansion of the boys' limited horizons.

Implements methods for clustering mixed-type data, specifically combinations of continuous and nominal data. Special attention is paid to the often-overlooked problem of equitably balancing the contribution of the continuous and categorical variables. This package implements KAMILA clustering, a novel method for clustering mixed-type data in the spirit of k-means clustering. It does not require dummy coding of variables, and is efficient enough to scale to rather large data sets. Also implemented is Modha-Spangler clustering, which uses a brute-force strategy to maximize the cluster separation simultaneously in the continuous and categorical variables.

Prime Distance
问题描述 :
The branch of mathematics called number theory is about properties of numbers. One of the areas that has captured the interest of number theoreticians for thousands of years is the question of primality. A prime number is a number that is has no proper factors (it is only evenly divisible by 1 and itself). The first prime numbers are 2,3,5,7 but they quickly become less frequent. One of the interesting questions is how dense they are in various ranges. Adjacent primes are two numbers that are both primes, but there are no other prime numbers between the adjacent primes. For example, 2,3 are the only adjacent primes that are also adjacent numbers.
Your program is given 2 numbers: L and U (1<=L< U<=2,147,483,647), and you are to find the two adjacent primes C1 and C2 (L<=C1< C2<=U) that are closest (i.e. C2-C1 is the minimum). If there are other pairs that are the same distance apart, use the first pair. You are also to find the two adjacent primes D1 and D2 (L<=D1< D2<=U) where D1 and D2 are as distant from each other as possible (again choosing the first pair if there is a tie).

You are also to find the two adjacent primes D1 and D2 (L<=D1< D2<=U) where D1 and D2 are as distant from each other as possible (again choosing the first pair if there is a tie).
输入:
Each line of input will contain two positive integers, L and U, with L < U. The difference between L and U will not exceed 1,000,000.
输出:
For each L and U, the output will either be the statement that there are no adjacent primes (because there are less than two primes between the two given numbers) or a line giving the two pairs of adjacent primes.
样例输入:
2 17 14 17
样例输出:
2,3 are closest, 7,11 are most distant. There are no adjacent primes.

These are the latest cases and convictions from Blackpool Magistrates Court - Friday, November 22, 2019
Here is today's round-up of cases from Blackpool Magistrates Court
by Colin AinscoughMichael Wood, 30, drink-driving
A man training to become a teacher was over the alcohol limit when a taxi driver saw him driving a damaged car.
Michael Wood was found at home by police who discovered his car in the garage there with two damaged tyres and scratched bodywork.
Wood, 30, of Coleridge Avenue, Thornton, pleaded guilty to drink-driving.
He was disqualified from driving for 15 months, fined £120 with £85 costs and ordered to pay £32 victims’ surcharge.
Prosecutor, Pam Smith, said a taxi driver reported to police he was driving behind a Fiesta with two badly damaged tyres, on November 2, at about midnight
Police traced Wood to his home and he told an officer he had hit something but he did not know what.
A breath test showed 51 microgrammes of alcohol in his body – 35 is the limit.
Martin Hillson, defending, said his client, who had no previous convictions, had gone for a night out with a woman and parked the car at a car park intending to take a tram home.
The night did not go well and the woman went off with some friends.
Wood drank some spirits and returned to the car park intending to put some more money on the car so it could stayed parked overnight.
Foolishly he succumbed to the temptation to drive home and clipped the kerb as he left the car park.
John Roach, 42, assault
A drink fuelled row over money led to a Blackpool man’s court appearance.
John Roach, 42, of George Street, North Shore, admitted assaulting his partner when he stood before the town’s magistrates.
Roach was given an 18 month community order which will contain 40 days rehabilitation and 120 unpaid work.
He must also pay £290 court costs.
Roach had started drinking at 7.30 am on the day of the crime. His partner also drank heavily, the court was told by Pam Smith prosecuting. They rowed over the payment of a debt and
Roach took his partner’s phone from her before punching her. Hugh Pond,defending, said: “My client has spent some time in prison awaiting this hearing. He is now coherent and sober.
His partner has been to see him whilst he was incarcerated.”
Keith Broadhead, 61, drink-driving
A man was over the alcohol limit and on his way to work in the morning when he collided with a motorcyclist.
Keith Broadhead, 61, of Heathway Avenue, Layton, pleaded guilty to driving with excess alcohol.
He was banned from the road for 14 months, fined £120 with £85 costs and ordered to pay £32 victims’ surcharge.
Prosecutor, Pam Smith, said police went to an accident on Preston New Road, on November 1, at 6.30am, where Broadhead, who was driving a Mercedes, had collided with a motorcyclist. The motorcyclist suffered cuts and bruises.
A breath test showed Broadhead had 44 microgrammes of alcohol in his body – 35 is the limit.
When interviewed, Broadhead said he was driving to work when he pulled out at a junction he thought was clear and the motorcyclist ran into the side of him.
He added he had been previously drinking cider and wine until 1am.
Robert Castle, defending, told magistrates that his client said he had absolutely no excuse.
Broadhead offered his apologies to the motorcyclist and had lost his job because of the offence.
John Robinson, 29, breach of restraining order
A chef broke the terms of a restraining order when he walked into the pub where his ex partner works and started to talk to her.
Magistrates ordered pre-sentence reports on John Robinson, 29, of The Conifers, Hambleton, who admitted breaching the order imposed by the court in October.
Pam Smith,prosecuting, said that Robinson wanted to talk to the woman over her pregnancy. She refused to talk in the pub bar and went into the kitchen and rang the police. Robinson was arrested and admitted what he had done. His lawyer, Robert Castle, told the hearing: “He did not make any threats. He was told by some of her friends she was worried.”


Elephant crosses train tracks by lifting level crossing gate in Jalpaiguri. Internet is worried
An elephant crossed train tracks by lifting a level crossing gate in North Bengal. The video has gone viral.
A video of an elephant crossing train tracks by lifting a level crossing gate surfaced on Twitter and has gone viral ever since. The over-one minute clip has been shared on Twitter by Susanta Nanda of the Indian Forest Service or IFS.
The elephant made a risky attempt to cross the train tracks in Jalpaiguri and fortunately succeeded. It appears from the video that nobody was present to operate the level crossing gate near the tracks. That didn't deter the elephant's attempt at all because it effortlessly lifted the level crossing gate and crossed the tracks.
It, thereafter, crossed the second level-crossing gate as well. In his caption for the video, Susanta Nanda said, "Level crossing or the train line won't stop this elephant to migrate. They remember their routes very well, passed from one generation to another. Interestingly, different techniques at both the ends."
Watch the video here:
The video has already been viewed over 32,000 times so far while the internet expressed concern for the elephant in the comments section. "It's fortunate that no train was running at that time. Could have easily resulted in horrible tragedy," a user wrote.
The internet's concern is valid considering that an elephant was left critically injured in September this year as the engine of a train hit the animal while it was trying to cross the tracks in a jungle in Jalpaiguri.

In this article we will cover the basic concepts of JavaScript and how to navigate and traverse the DOM, in order to make your website interactive.
JavaScript and HTML CSS
It is important to understand a little bit of the history of the language. JavaScript was created in 1995 by Brendan Eich while he was an engineer at Netscape. JavaScript was first released with Netscape 2 early in 1996. It was originally going to be called LiveScript, but it was renamed in an ill-fated marketing decision that attempted to capitalize on the popularity of Sun Microsystem's Java language — despite the two having very little in common. This has been a source of confusion ever since.
So far we have learnt that, HTML and CSS are programming languages (in my opinion, some may disagree), that don't use logic, HTML is where you set the basic structure of the page, is the most basic building block of the Web, It defines the meaning and structure of web content and CSS where you give style to that page. JavaScript is an advanced programming language that makes web pages more interactive and dynamic. It manipulates content to create dynamic web pages.
My analogy to understand these three concepts, think of HTML and CSS as the structure of the car, the paint job and all the accessories. JavaScript is the engine that makes it run, it provides power to the car so you can interact with it.
Control Flow and Loops
The control flow is the order in which the computer executes statements in a script. In JavaScript, we read the code starting from the first line till the last line unless of course in the code there is some instructions or statements that changes that control flow.
if/else statement
The most well known control flow is the 'if'/'else' statement. For instance, you want a website to show a page 'if' you are older than 18, otherwise or 'else', the website would render a different page, this is a conditional statement. The code would be something like this:
if(age >= 18) {
// Load the page
} else {
// Warning page!
}
Switch statement
Another very common conditional statement used as control flow is the 'switch' statement. The switch statement is used when you have to use many if statements in the same function, it evaluates an expression, matching the expression’s value to a case clause, and executes statements associated with that case.
switch(car){
case 'has no gas':
// go to the gas station
break;
case 'flat tyre':
// replace tyre
break;
default:
// start the engine
}
If you don't add the break statement, the execution will 'fall through' to the next level. This may not be what you want, in case you want that to happen you can specify and it is worth commenting to show your intentions.
Loop
'for' loop
Creates a loop that consists of three optional expressions, enclosed in parentheses and separated by semicolons, followed by a statement executed in the loop.
the syntax of the for loop is:
for(initialExpression; condition; updateExpression) {
// for loop body
}
- the initialExpression initializes and/or declares variables and executes only once.
-
The condition is evaluated.
- If the condition is false, the for loop is terminated.
- If the condition is true, the block of code inside of the for loop is executed
- The updateExpression update s the value of the initialExpression when the condition is true
- The condition is evaluated again. This process continues until the condition is false
for...in
Iterates over the enumerable properties of an object, in arbitrary order. For each distinct property, statements can be executed.
const obj = {a: 1, b: 2, c: 3};
for (const prop in obj) {
console.log(`obj.${prop} = ${obj[prop]}`);
}
// Output:
// "obj.a = 1"
// "obj.b = 2"
// "obj.c = 3"
for...of
Iterates over iterable objects (including arrays, array-like objects, iterators and generators), invoking a custom iteration hook with statements to be executed for the value of each distinct property.
const iterable = [10, 20, 30];
for (let value of iterable) {
value += 1;
console.log(value);
}
// 11
// 21
// 31
The DOM
According to W3C, the document object model (DOM) is an "application programming interface for valid HTML and well-formed XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated".
In simple terms, the DOM is a representation of your HTML to the browser and allows you to manipulate the page.
It is often referred to as a tree because the DOM with a single parent item that branches out into children items. These children items can also branch out into their own smaller trees like what you see in the photo above.
While the DOM sounds like this super intimidating thing, it's actually how browsers determine what is rendered on our page and, through JavaScript, is how we can manipulate those elements that are rendered.
Objects and Arrays
Objects
Objects are used to represent a “thing” in your code. That could be a person, a car, a building, a book, a character in a game — basically anything that is made up or can be defined by a set of characteristics. In objects, these characteristics are called properties that consist of a key and a value.
// Basic object syntax
const object = {
key: 'value'
};
// Example 'person' object
const person = {
name: 'Zac',
age: 33,
likesCoding: true
};
Accessing data from objects
Properties in objects can be accessed, added, changed, and removed by using either dot or bracket notation. To get the value of the age key in our personobject with both dot and bracket notation, we’d write:
// Dot notation
person.age // returns 33
// Bracket notation
person['age'] // returns 33
Arrays
We use arrays whenever we want to create and store a list of multiple items in a single variable. Arrays are especially useful when creating ordered collections where items in the collection can be accessed by their numerical position in the list. Just as object properties can store values of any primitive data type (as well as an array or another object), so too can arrays consist of strings, numbers, booleans, objects, or even other arrays.
Accessing data from arrays
Arrays use zero-based indexing, so the first item in an array has an index of 0, the second item an index of 1, and so on. For instance, let’s say we wanted to access the third item (‘Mexico City’) in the following array:
const cities = ['Tokyo', 'Bali', 'Mexico City', 'Vancouver'];
cities[2]; // returns 'Mexico City'
Objects represent “things” with characteristics (aka properties), while arrays create and store lists of data in a single variable. Both dot and bracket notation allow us to access, add, change, and remove items from an object, while zero-based indexing and a variety of built-in methods let us access and alter items in an array.
Functions
What is a Function?
 Functions are executed when they are called. This is known as invoking a function. Values can be passed into functions and used within the function. Functions always return a value. In JavaScript, if no return value is specified, the function will return undefined.
Define a function
A Function Declaration defines a named function. To create a function declaration you use the function keyword followed by the name of the function. When using function declarations, the function definition is hoisted, thus allowing the function to be used before it is defined.
function name(parameters){
statements
}
Parameters vs Arguments
If you’re new to JavaScript, you may have heard the terms parameters and arguments used interchangeably. While very similar, there is an important distinction to make between these two keywords.
Parameters are used when defining a function, they are the names created in the function definition. In fact, during a function definition, we can pass in up to 255 parameters! Parameters are separated by commas in the (). Here’s an example with two parameters — param1 & param2:
const param1 = true;
const param2 = false;
function twoParams(param1, param2){
console.log(param1, param2);
}
Arguments, on the other hand, are the values the function receives from each parameter when the function is executed (invoked). In the above example, our two arguments are true & false.
That was a lot of information, and there is still a lot to cover in this topic. JavaScript has unlimited possibilities, it's one of the most versatile and flexible programming languages, so don't worry if you don't know it all, you never will, for now, lets focus on the fundamentals.


SPT Relational Database Web Tool
Application Manual
Version 1.2
Prepared by
Rakesh Vidyadharan
Dated: October 14, 2007
Contents
1 Introduction
The SPT Relational Database Web Tool (RWT) is a simple application that can help developers connect
to databases configured as DataSource in the application server, or directly through JDBC. The RWT
application attempts to replicate basic features found in the popular Aqua Data Studio application.
Some simple use cases used as the primary requirements for developing the tool are listed in the
appendix.
1.1 Features
The following are the basic features provided by the tool:
- Connect to databases configured in application server as DataSources. Configured
DataSources are displayed in the application menu.
- Display a Connection dialogue through which users may specify the parameters for directly
connecting to a database through JDBC. The connection parameters may be saved in which
case the Connection will be added to the application menu of available databases.
- Display in a Tree the following types of database objects available in the connected
database.
- The schemas accessible to the user.
- The tables available under a schema.
- The views available under a schema.
- The procedures and functions available under a schema.
- The triggers defined in a schema.
- The constraints (primary and foreign keys) defined in a schema.
- A query exeecution tool launched through a menu (multiple windows are supported). The query
tool makes the following features available:
- A free text area in which the user enters the query they wish to execute.
- An optional text field which can be used to limit the maximum number of matching
records fetched from the database.
- A “Save” button that can be used to save the current query for easy access via a
menu in the future.
- The results of the query are displayed in tabular format. The results are pageable
and sortable for convenience.
- The results of the query can be exported to Excel through a “Export to Excel” button.
1.2 Technology
The RWT application was developed using Echo2 and EchoPointNG for the User Interface and JDBC for
database access. Database metadata is fetched using standard JDBC as well as the Information Schema
supported by most databases.
Echo2 was used to develop the User Interface to maximise developer productivity. Echo2 helps
developers avoid the impedence mismatch between having to implement business logic in Java, and
implement the display logic using totally different languages such as XHTML 1.0, JavaScript,
…
2 Installation
The RWT application is relatively easy to install. Table 1Software Requirements shows the minimum
versions of the software necessary to install the application. The following steps need to be executed to
deploy the application to the application server.
- Download the sptrwt.zip file from the project home page.
- Extract the sptrwt.war file from the downloaded zip archive.
- Create the central directory under which application support files are located. Support
files are used to store saved Connection details, saved queries etc. Note that the central
directory may need to be on a file server if you wish to deploy the application to multiple
nodes. For example, Sans Pareil Technologies, Inc. uses a /var/data/rwt directory as the
application directory.
- Configure a DataSource named jdbc/rwt in your application server. Refer to the building
instructions (see section 3.1) if you wish to configure additional DataSources, or use a
differnt DataSource name.
- Configure a JVM system property named sptrwt.data.directory for the container.
Listing 1lstlisting shows the steps involved in configuring the property For Tomcat. example,
add a line similar to the following to $CATALINA_BASE/bin/catalina.sh
- Deploy the war file to the application server.

With over five years of experience, we have competed in several competitions and won numerous awards.
As engineering students, our #1 Rule when creating alternative solutions is to not settle for the first idea. During this phase, we try to generate as many possible solutions as we can before choosing one that we feel is the best. This creative process of developing ideas is called ideation. The key to brainstorming is to remember that no idea is a bad idea! Each idea, no matter how off-the-wall it seems, should be recorded during the brainstorming session. The more ideas that are generated, the more likely it is that a successful design will result.
In this stage of the process we takes some of the concepts from the previous step and make mock-up versions of them. The goal of this stage is to learn how each concept solution will function in a competition scenario. This is also where a we determine which design concept will work the best. These prototypes are designed to be crude, but functional enough to be educational to the builder.
This is the stage of the design process where we take our chosen concept and make it into something more “real.” This stage is all about the details. By the end of this stage, our team has everything necessary to construct the full design.
In competitive robotics it is a good idea to make a 3D model of the entire robot in Autodesk Inventor. This can be one of the longest stages in the design process, but the work pays off. The more work put into the design of the robot, the easier it will be to make it.
This is the phase where we “build the robot.” All the details done during the refining phase are used to create a finished, functional robot to compete with (or a subsystem that is part of a larger finished product)! This stage can involve purchasing components, cutting parts, assembly, and more - anything it takes to produce a final product.
This is also the stage where we produce marketing packets, award submissions, and other materials related to the competition, but not associated with the robot. These items are all part of the final implementation.

The unit called FullSpectrum takes an input data type containing a spectrum
and outputs a full-spectrum type, restoring it to its full width if it
was narrow-band and to two-sided form if it was one-sided. Narrow-band
spectra are made wide-band by inserting zeros. Two-sided-ness is restored
assuming the spectrum came from a real data set, so that the negative frequencies
hold complex conjugate values of those at the positive frequencies.

Game on the go with these Alienware laptops on sale for Black Friday
by Joseph GreenTL;DR: Save an extra 15% on Alienware M15 gaming laptops with the code AW15.
Gamers are a demanding bunch, and they need to be because if a device can't keep up, it's going to seriously affect the experience of everyone involved.
There are a number of top gaming brands that consistently deliver devices that impress even the most demanding of customers. We're talking about the likes of Logitech, Corsair, Razer, and of course, Alienware. There is no brand with quite the same reputation as Alienware when it comes to performance, and that's why it doesn't come cheap.
There are two things you know for sure with Alienware: It's going to perform and it's going to be expensive. This is why it pays to wait until Black Friday to invest in a device from this brand.
You can now save an extra 15% on Alienware M15 gaming laptops with the code AW15. This is possibly the best deal from the Dell Black Friday pre-sale, that has been up and running for a while now. It's worth checking out the full range of discounted laptops and desktops, with potential savings of up to £440.
Demand the best and save on Alienware in the Dell Black Friday pre-sale.
