Surface Class
A widget that provides pan/zoom functionality, as well as the ability to load/store state in the browser.
You do not construct an instance of this class manually: you obtain an instance of Surface via a call to the render
method on a jsPlumbToolkitInstance
. But the supported parameters to that render
method are whatever is supported by
the Surface constructor, as documented here.
Constructor
Surface
-
params
-
[params.zoomRange=[0.05,
Parameters:
-
params
ObjectConstructor parameters
-
container
Element | SelectorElement to convert into a Surface.
-
[elementsDraggable=true]
Boolean optionalWhether or not elements in the Surface should be draggable.
-
[dragOptions]
Object optionalOptions for draggable nodes.
-
[events]
Object optionalOptional event bindings. See documentation.
-
[miniview]
Object optionalOptional miniview configuration.
-
[container]
Element | String | Selector optionalContainer for the miniview. An Element, an element id, or a selector. -
[initiallyVisible=true]
Boolean optionalWhether or not the miniview should be invisible until some data is loaded.
-
-
[mode="Pan"]
String optionalMode to initialize the Surface in.
-
[panDistance=50]
Number optionalHow far a pan nudge should move the UI (in pixels).
-
[zoom=1]
Number optionalInitial zoom for the widget.
-
[enablePan=true]
Boolean optionalWhether or not panning (via mouse drag) is enabled.
-
[enableWheelZoom=true]
Boolean optionalWhether or not zooming with the mouse wheel is enabled.
-
[enableAnimation=true]
Boolean optionalEnable animations for panning. Defaults to true.
-
[wheelFilter]
String optionalOptional CSS selector representing elements that should not respond to wheel zoom.
-
[panFilter]
String | Function optionalOptional; either a CSS selector representing elements that should allow a pan event to begin, or a function that will be called with the event target. Returning true from this function means the widget should respond to the event.
-
[wheelSensitivity=10]
Number optionalHow many pixels each click of the mouse wheel represents when zooming. Note that this value, while expressed in pixels, is mapped in a variety of ways depending on the browser.
-
[wheelZoomMetaKey=false]
Boolean optionalIf true, the "meta" key (CMD on Mac, Ctrl on windows/linux) must be pressed in order for wheel zoom to operate. This can be useful if your UI fills the screen in one or more axes and your users would not be able to scroll past the Surface widget.
-
[enablePanButtons=true]
Boolean optionalWhether or not to show the pan nudge buttons on the borders of the widgets.
-
[padding]
Number optionalOptional values for padding in the x/y axes to leave around the content. This is only of any use if you have disabled panning via mouse drag, since in that case the user sees only scroll bars and has no way of navigating beyond the content. Some padding makes the UI nicer to use. Default is [0,0].
-
[lassoFilter]
String optionalOptional selector for elements on which a mousedown should not cause the lasso to activate.
-
[lassoInvert=false]
Boolean optionalIf true, the lasso operates by masking the unselected parts of the display.
-
[lassoSelectionFilter]
Function optionalOptional function that can be used to filter the set of nodes a lasso drag is selecting. The function is given each candidate Node in turn; returning false indicates the Node should not be selected.
-
[consumeRightClick=true]
Boolean optionalUseful for development: set this to false if you don't want the widget to consume context menu clicks.
-
[stateHandle]
String optionalIf supplied, this will be used as the default handle for state save/restore operations.
-
[clamp=true]
Boolean optionalWhether to clamp when panning such that there is always content visible.
-
[clampZoom=true]
Boolean optionalWhether to clamp when zooming such that there is always content visible.
-
[clampToBackground=false]
Boolean optionalIf a background is set, whether to clamp movement such that some part of the background is always visible.
-
[clampToBackgroundExtents=false]
Boolean optionalIf a background is set, whether to clamp movement such that the background fills as much of the viewport as it can.
-
[background]
Object optionalOptional background image parameters
-
[url]
String optionalURL for the background. Required for both single images and tiled backgrounds. -
[type="simple"]
String optional"simple" or "tiled" - the type of background. -
[tileSize]
Number optionalFor tiled backgrounds, provides the width and height of tiles. Every tile is assumed to have these dimensions, even if the tile has whitespace in it. -
[width]
Number optionalRequired for tiled backgrounds. Indicates the width of the full image. -
[height]
Number optionalRequired for tiled backgrounds. Indicates the height of the full image. -
[maxZoom]
Number optionalRequired for tiled backgrounds. Indicates the maximum zoom level. Zoom starts at 0 - fully zoomed out - and increases in integer values from there. Eash successive zoom level is twice the zoom of the previous level, meaning two times as many tiles in each direction.
-
-
[jsPlumb]
Object optionalOptional set of jsPlumb Defaults to use for this renderer. The format and allowed properties is that of the Defaults object in jsPlumb. You can also set display properties in the view.
-
[autoExitSelectMode=true]
Boolean optionalWhen true (which is the default), the Surface will automatically jump back into Pan mode after some nodes have been selected.
-
[zoomToFit=false]
Boolean optionalIf true, content will be zoomed to fit the viewport when a dataLoadEnd event is received.
-
[zoomToFitIfNecessary=false]
Boolean optionalIf true, content will be zoomed to fit the viewport, if necessary (meaning if it fits inside the viewport already it wont be zoomed, which is different from how
zoomToFit
works) when a dataLoadEnd event is received. If this andzoomToFit
are both set, this takes precedence. -
[storePositionsInModel=true]
Boolean optionalBy default, the left/top positions of nodes that have been dragged will be written into the data for each node after drag stops. You can set this to false to disable that behaviour.
-
[modelLeftAttribute="left"]
String optionalOptional; specifies the name of the attribute by which to store the x position of a dragged node of
storePositionsInModel
is true. -
[modelTopAttribute="top"]
String optionalOptional; specifies the name of the attribute by which to store the y position of a dragged node of
storePositionsInModel
is true. -
[assignPosse]
Function optionaloptional function that, given each node, can return the id of the posse to which the node belongs. a Posse is a group of nodes that should all be dragged together.
-
[relayoutOnGroupUpdate=false]
Boolean optionalIf true, any change to a Group's nodes will cause a relayout.
-
-
[params.zoomRange=[0.05,
Number3] ] Zoom range for the widget.

Returns:
[left,top], in pixels, of the panned content, where [0,0] is the origin of the viewport.
getStateHandle
()
String
Gets the default handle to use for state save/restore operations.
Returns:
Handle in use.
getViewportCenter
()
Number
Gets the canvas location that corresponds to the center of the viewport. Note that this may describe a point outside of the content bounds.

nudgeWheelZoom
-
delta
-

for a more general version of this.
Parameters:
-
delta
NumberAmount to change zoom by.
-
[e]
Event optionalOriginal event that caused the nudge. May be null.
nudgeZoom
-
delta
-
[e]
Nudges the zoom by the given amount. Zoom will be clamped to the current zoom range in effect and the value that was ultimately set is returned from this function. The value you pass in here is multiplied by 100 to give a percentage value: 1 is 100%, for instance, 0.05 is 5%.
Parameters:
-
delta
NumberAmount to change zoom by.
-
[e]
Event optionalOriginal event that caused the nudge. May be null.
Returns:
The zoom that was set. Zoom will be clamped to the allowed range.

-
[animate
Pans the content by dx and dy.
Parameters:
-
dx

-
x
-
y
-
[xShift=0]
-
[yShift=0]
Places (using style.left
and style.top
) the given element at the given x,y, which is taken to
mean an [x,y] value on the canvas. At zoom 1, with no panning, this will be the same as the given [x,y] value
relative to the viewport origin. But once the canvas has been zoomed and panned we have to map
to the altered coordinates. This function also takes into account the difference between the offset of the
viewport in the page and the offset of the given element. It is assumed, just because of what this method
does, that the given element will be positioned absolute
, but this method does nothing to ensure that.
Note that this method - and its relatives, positionElementAtEventLocation
and positionElementAtPageLocation
- are
not intended for use with elements being managed by the Surface. They are for use with external
elements that you need to align with the contents of the Surface.
Parameters:
-
el
Selector | Element | StringElement to position.
-
x
NumberX location on canvas to move element's left edge to.
-
y
NumberY location on canvas to move element's top edge to.
-
[xShift=0]
Number optionalOptional absolute number of pixels to shift the element by in the x axis after calculating its position relative to the canvas. Typically you'd use this to place something other than the top left corner of your element at the desired location.
-
[yShift=0]
Number optionalOptional absolute number of pixels to shift the element by in the y axis after calculating its position relative to the canvas.
positionElementAtEventLocation
-
el
-
evt
-
[xShift=0]
-
[yShift=0]
Places (using style.left
and style.top
) the given element at the page x,y corresponding to the given
event. It is assumed, just because of what this method does, that the given element will be positioned
absolute
, but this method does nothing to ensure that. Note that this method - and its relatives,
positionElementAt
and positionElementAtPageLocation
- are not intended for use with elements being
managed by the Surface. They are for use with external elements that you need to align with the contents
of the Surface.
Parameters:
-
el
Selector | Element | StringElement to position.
-
evt
EventEvent to position element at.
-
[xShift=0]
Number optionalOptional absolute number of pixels to shift the element by in the x axis after calculating its position relative to the canvas. Typically you'd use this to place something other than the top left corner of your element at the desired location.

y
-
[xShift=0]
-
[yShift=0]
Places (using style.left
and style.top
) the given element at the given page x,y. It is assumed, just
because of what this method does, that the given element will be positioned absolute
, but this method
does nothing to ensure that. Note that this method - and its relatives, positionElementAtEventLocation

handle
Saves the current state of the UI, either to local storage or a cookie, depending on the browser's capabilities.
Parameters:
-
handle
StringThe handle to save the state as, If this is not supplied, and
stateHandle
was supplied as a constructor parameter, that is used instead.
selectAllEdges
-
params
Selects a set of Edges. Parameters are the same as for selectEdges; the difference here is that when you're working with Nodes, this method will return all of the Node's Edges as well as those of all the Ports registered on the Node.
Parameters:

determined, and the edges for that object will be retrieved. Note that for a Port this method does the same thing as
selectAllEdges
, but for a Node, which may have Ports registered on it, this method will retrieve only the Edges directly
registered on the Node itself. You may need to use selectAllEdges
if you want everything from some Node.

State.deserialize
-
value
Restores the UI state to the serialized state given.
Parameters:
-
value
StringSerialized state.
State.restore
-
[handle]
-
[preprocessor]
Restores the UI state to the state it was in when it was saved with the given handle. If the handle does not exist, nothing happens. It is possible a future incarnation of this could support animating a UI back to some state.
Parameters:
-
[handle]
String optionalThe handle to restore the state from, If this is not supplied, and
stateHandle
was supplied as a constructor parameter, that is used instead. -
[preprocessor]
Function optionalOptional preprocessor which is given the serialized state before saving to localStorage. Useful if you wish to compress the data, for instance.
State.save
-
[handle]
-
[preprocessor]
Writes the current location of each node in the UI to local storage (using either a cookie or html5 storage, depending on browser capabilities). You pass this function a 'handle' argument, which is used to restore the state at some stage in the future.
Parameters:
-
[handle]
String optionalThe handle to save the state as, If this is not supplied, and
stateHandle
was supplied as a constructor parameter, that is used instead. -
[preprocessor]
Function optionalOptional preprocessor which is given the serialized state, and a callback function, before saving to localStorage. Useful if you wish to compress the data, for instance.
State.serialize
()
Serializes the UI state to a String.
stopEditing
-
edgeOrConnection
Stops editing of the given Edge, Connection, or Edge ID.
Parameters:
-
edgeOrConnection
String | Edge | ConnectionEither an Edge, or a Connection, or an Edge ID.
zoomToBackground
-
[params]
Zooms the display so that the background fits inside the viewport.
Parameters:
-
[params]
Object optional-
[onComplete]
Function optionalOptional function to call on operation complete (centering may be animated).
-
[onStep]
Function optionalOptional function to call on operation step (centering may be animated).
-
[doNotAnimate=false]
Boolean optionalIf true, centering content will not use animation.
-
zoomToFit
-
[params]
Zooms the display so that all the tracked elements fit into 90% of the viewport. This method will also,
by default, increase the zoom if necessary - meaning the default behaviour is to adjust the zoom so that
the content fills the viewport. You can suppress zoom increase by setting doNotZoomIfVisible:true
on the
parameters to this method. You can supply a fill
parameter to tell the Surface how much of the viewport
you wish to fill with the zoomed content if 90% is not to your liking.
Parameters:
-
[params]
Object optional-
[fill=0.90]
Number optionalA decimal indicating how much of the viewport to fill with the zoomed content.
-
[padding=20]
Number optionalOptional padding to leave around all elements.
-
[onComplete]
Function optionalOptional function to call on operation complete (centering may be animated).
-
[onStep]
Function optionalOptional function to call on operation step (centering may be animated).
-
[doNotAnimate=true]
Boolean optionalBy default, the centering content step does not use animation. This is due to this method being used most often to initially setup a UI.
-
[doNotZoomIfVisible=false]
Boolean optionalIf true, no action is taken if the content is currently all visible.
-
[doNotFirePanEvent=false]
Boolean optionalIf true, a pan event will not be fired.
-
zoomToFitIfNecessary

Module : time
Module overview
This module provides implementations related to time, date, time zones, and durations.
The module has two main types as Time and TimeZone. The type Time
represents a time associated with a given time zone. It has time
and zone
as attributes. The type TimeZone
represents the time zone associated with a given time. It has id
and offset
as attributes. An id
can be one of the following:
- If
id
equals 'Z', the result is UTC. - If
id
equals 'GMT', 'UTC' or 'UT', it is equivalent to UTC. - If
id
starts with '+' or '-', the ID is parsed as an offset. Offset can be specified in one of the following ways. +h, +hh, +hh:mm, -hh:mm, +hhmm, -hhmm, +hh:mm:ss, -hh:mm:ss, +hhmmss, -hhmmss - Also
id
can be a region-based zone ID. The format is '{area}/{city}' eg: "America/Panama". The zones are based on IANA Time Zone Database (TZDB) supplied data.
Samples
Getting the current time/date
import ballerina/io;
import ballerina/time;
public function main() {
time:Time time = time:currentTime(); // Create a record of type ‘Time’.
io:println(time);
int timeValue = time.time; // Time in milliseconds since January 1, 1970, 00:00:00 GMT. E.g.,<PHONE_NUMBER>.
io:println(timeValue);
int nanoTime = time:nanoTime(); // Time in nanoseconds since an arbitrary origin. Therefore, it should be used only to calculate durations. E.g.,<PHONE_NUMBER>486340.
io:println(nanoTime);
string zoneId = time.zone.id; // Time zone as an identifier. E.g., “America/Panama”.
io:println(zoneId);
int zoneoffset = time.zone.offset; // Time zone as an offset. E.g., -05:00.
io:println(zoneoffset);
// Get the current date and time upto milliseconds.
int year = time:getYear(time); // E.g., 2018
io:println(year);
int month = time:getMonth(time); // E.g., 3
io:println(month);
int day = time:getDay(time); // E.g., 1
io:println(day);
int hour = time:getHour(time); // E.g., 18
io:println(hour);
int minute = time:getMinute(time); // E.g., 56
io:println(minute);
int second = time:getSecond(time); // E.g., 23
io:println(second);
int milliSecond = time:getMilliSecond(time); // E.g., 555
io:println(milliSecond);
string weekday = time:getWeekday(time);// Day of the week. E.g., “TUESDAY”.
io:println(weekday);
}
Creating a time/date record
import ballerina/io;
import ballerina/time;
public function main() {
// Create a record of type ‘Time’ with time zone.
time:TimeZone zoneIdValue = {id: "America/Panama"};
time:Time time1 = {time:<PHONE_NUMBER>000, zone: zoneIdValue};
io:println(time1);
// Create a record of type ‘Time’ with the time zone offset.
time:TimeZone zoneOffsetValue = {id: "-05:00"};
time:Time time2 = {time:<PHONE_NUMBER>000, zone: zoneOffsetValue};
io:println(time2);
// Create a record of type ‘Time’ without the time zone.
time:TimeZone noZoneValue = {id: ""};
time:Time time3 = {time:<PHONE_NUMBER>000, zone: noZoneValue};
io:println(time3);
// Create a record of type ‘Time’ with time and date. E.g., 2018-03-28T23:42:45.554-05:00
time:Time | error dateTime = time:createTime(2018, 3, 28, 23, 42, 45, 554, "America/Panama");
if (dateTime is time:Time) {
io:println(dateTime);
} else {
io:println("An error occurred: ", dateTime);
}
}
Formatting a time/date to a string
import ballerina/io;
import ballerina/time;
public function main() returns error? {
time:TimeZone zoneValue = {id: "America/Panama"};
time:Time time = {time:<PHONE_NUMBER>444, zone: zoneValue};
//Format a time to a string of a given pattern.
string | error time1 = check time:format(time, "yyyy-MM-dd'T'HH:mm:ss.SSSZ"); //E.g., “2017-06-26T09:46:22.444-0500”.
io:println(time1);
//Format a time to a string of the RFC-1123 format.
string | error time2 = time:format(time, time:TIME_FORMAT_RFC_1123); // E.g., "Mon, 26 Jun 2017 09:46:22 -0500”
io:println(time2);
// Convert a time record to a string value.
string time3 = time:toString(time);//”2017-06-26T09:46:22.444-05:00”
io:println(time3);
}
Parsing a string to time/date
import ballerina/io;
import ballerina/time;
public function main() returns error? {
// Parse a time string of a given format.
time:Time | error time1 = time:parse("2017-06-26T09:46:22.444-0500", "yyyy-MM-dd'T'HH:mm:ss.SSSZ"); // The ‘Z’ stands for the time zone.
io:println(time1);
// Parse a time string of the RFC-1123 format.
time:Time | error time2 = time:parse("Wed, 28 Mar 2018 11:56:23 +0530", time:TIME_FORMAT_RFC_1123);
io:println(time2);
}
Setting time durations
import ballerina/time;
public function main() {
// Add a duration to a given time.
time:Time | error time1 = time:parse("2017-06-26T09:46:22.444-0500", "yyyy-MM-dd'T'HH:mm:ss.SSSZ");
if (time1 is time:Time) {
time1 = time:addDuration(time1, 1, 1, 1, 1, 1, 1, 1);
// Adds 1 year, 1 month, 1 day, 1 hour, 1 minute, 1 second, and 1 millisecond.
}
// Subtract a duration from a given time.
time:Time | error time2 = time:parse("2016-03-01T09:46:22.444-0500", "yyyy-MM-dd'T'HH:mm:ss.SSSZ");
if (time2 is time:Time) {
time2 = time:subtractDuration(time2, 1, 1, 1, 1, 1, 1, 1);
// Subtracts 1 year, 1 month, 1 day, 1 hour, 1 minute, 1 second, and 1 millisecond.
}
// Get the duration between two times.
time:Time time3 = time:currentTime();
time:Time time4 = time:currentTime();
int diffInMillis = time3.time - time4.time;
}

I finally got round to buying some galanga yesterday (UKP 1.60 per pound). Got home and chopped up about 2oz of the stuff (after peeling) and wanting to keep an empty stomach (just in case :) simply fried it gently in oil before eating it. I rapidly came to regret this decision - it tastes more than anything like pine sap with quite a woody texture. Yuk.
About half an hour after finally forcing it down I had to catch a bus. Standing by a main road in the dark I realised that the headlights were building up strange trails - the 'morning after tripping' comparison seemed a good one. Felt quite mellow - like a voice whispering 'Go on, relax...' but not forcing it. Faint but definite physical tingles - plus, galanga's comparable in heat to fresh ginger, and my stomach may well have felt strange due to that.
Some two and a half hours in things were getting better. All physical symptoms had subsided and I could get 'acid lights' to come on by staring at something for four or five seconds, with comparable distortions to, say half an average trip (maybe 50-60ug). My resistance to dope was very high, as when tripping, and I felt myself in a good mood, smiling bemusedly at people rather than talk to them.
I was still 'up' nearly six hours after dropping and a goodish amount of dope. Eight fingers of scotch later this didn't seem to be a problem any more; I staggered off to bed feeling rather pissed and got to sleep fairly easily (c.1.30 am). Trails were pretty good last night; they've now faded. I'm tired (5.5 hours sleep) and slightly disoriented (and not inclined to work much) but otherwise ok.
Summary: All the above for about 60 cents, so one can hardly complain. I intend to try it with acid - the dope resistance could get irritating if one wished to get stoned. Galanga more than lived up to my (fairly low) expectations.

You will want to get hold of lists of IP addresses if you want to use the blacknets feature of nftfw (v0.7.0 or later) to block access from certain countries or IP address ranges. If you want to use this system, check that the version of nftfw you have installed is configured to support it, see How to check nftfw supports_blacknets at bottom of this page.
To use blacknets, you need a file or files containing IP networks, one per line, using ‘CIDR’ notation. See Wikipedia if you need more information on CIDR.
There are several sources for lists of networks by country, I’ve used two.
This company, based in the Isle of Man, has been collating IP addresses for many years. They offer a free download of IP addresses per country in several formats aimed at different applications. Visit their page Block Visitors by Country Using Firewall and scroll to the bottom of the page for the form.
There are three drop-down menus: choose the country, select IPv6, and CIDR and click DOWNLOAD. The file will be downloaded to your machine.
Place the file in blacknets.d, remembering to add .nets as the file suffix.
The IPv6 file contains all the IPv4 addresses, and nftfw’s reader will convert the addresses into the correct format.
The downside of this is that you have to download the file by hand, but it’s easy to use as a starter.
If you’ve installed the GeoLite2 database from Maxmind to assist with identifying countries with nftfwls, then with some little work you can access their country database and also have your system refresh it once a week.
The script you are about to install looks for your MaxMind license information in /etc/GeoIP.conf, so you need to install the Geolocation system first, see Installing Geolocation.
You’ll need wget
, so
sudo apt install wget $
Navigate to the nftfw release and find the cidrlist directory. Install the shell script getgeocountry
that pulls the database from MaxMind:
sudo cp getgeocountry /var/lib/GeoIP
$ cd /var/lib/GeoIP
$ sudo chown root.root getgeocountry
$ sudo chmod +x getgeocountry $
run it
sudo getgeocountry $
The script will have created several files, culminating in GeoLite2-Country.db containing an sqlite3 database made from the downloaded information.
Make this script run once a week by placing a line in the cron file provided as part of the geoipupdate package. Edit /etc/cron.d/geoipupdate adding:
30 7 * * 3 root /var/lib/GeoIP/getgeocountry
I run mine an hour after the weekly run of geoipupdate, so please do choose the hour and minute to be different from the world.
Return to the nftfw distribution and find the cidrlist directory again. The getcountrynet
script uses the database installed in Step 1 to create a country CIDR file. Install the script:
sudo cp getcountrynet /etc/nftfw
$ cd /etc/nftfw
$ sudo chown USER.USER getcountrynet
$ sudo chmod +x getcountrynet $
The USER.USER here should be whoever owns the /etc/nftfw directory (may be /usr/local/etc/nftfw on your machine). I’ve installed my command file in this directory on the grounds of ‘keeping everything together’, but you can put it anywhere that’s convenient.
Now run the script as the owner of the directory or use sudo and change ownership afterwards. To run, you can give it any number of two letter ISO country codes and it will create a matching file in blacknets.d.
getcountrynet GB fr $
will create files called GB.nets and fr.nets in blacknets.d. Remember that file systems are case-dependent, so choose your capitalisation and stick with it. I’m assuming you replace the arguments with a country or countries that you want to block.
If you are confident that you’ve got an appropriate version of nftfw (see below), you can now install the new tables, prudently running a test first:
sudo nftfw -x load $
All being well, you can then install the new tables:
sudo nftfw -f load $
Finally tell cron to run the getcountrynet
script. Again, I’ve added a new line to the /etc/cron.d/geoipupdate adding:
55 7 * * 3 USER /etc/nftfw/getcountrynet COUNTRIES
the USER should be whoever owns the files, and the arguments should match the ones you typed in earlier.
The blacknets feature from v0.7.0 of nftfw requires a change in the firewall template file /etc/nftfw/nftfw_init.nft. You may need to check you’ve updated the nftfw_init.nft file before running nftfw with the CIDR files. This file requires updating by hand, and you may have not installed it.
It the file doesn’t contain the string blacknets, then you need to update it.
cd /etc/nftfw
$ grep blacknets nftfw_init.nft $
If the command gives no output, check the copy of the file in the etc_nftfw directory using grep.
grep blacknets /etc/nftfw/etc_nftfw/nftfw_init.nft $
If this gives output, then copy the originals file over your running version, carefully re-applying any changes you’ve made.
If there is no output from grep on the copy in etc_nftfw, you need to update your nftfw installation to a version after v0.7.0. See Updating nftfw.
You can create as many files as you like in blacknets.d as long as they are in the correct format. To remove a set from the firewall, simply remove the file.
The files can contain a lot of IP addresses, and processing them can take some time. The reader will cope with automatic detection of IPv4 and IPv6, the conversion of IPv4 addresses when expressed in IPv6 format (which ip2location.com uses), and the removal of some addresses that look like networks but are not. It will also remove duplicates and compresses the IP list down to a set of unique networks. It’s possible to run CIDR files from both of the sources shown in this document, and reduce them to a minimal set.
Generally, the files in blacknets.d change rarely, so nftfw will cache processed information on the first reading of the files and will read from the cache when it needs the data to build the firewall. The cache is always reloaded when files in blacknets.d alter or come and go. In addition, the -f
flag to nftfw will clear the cache and start again.

Easily OCR images, barcodes, forms, documents with machine readable zones, e.g. passports, right from R. Get the results in a wide variety of formats, from text files to detailed XMLs with information about bounding boxes, etc.
The package provides access to the Abbyy Cloud OCR SDK API. Details about results of calls to the API can be found here.
To get acquainted with some of the important functions, read the vignettes:
# Overview of the package
vignette("introduction", package = "abbyyR")
# some functions are used along with output
vignette("example", package = "abbyyR")
# how to scrape text from a folder of images
vignette("wiscads", package = "abbyyR")
The final output quality varies by complexity of the layout to resolution to font face etc. To measure the final quality of ocr, you can measure the edit distance to `gold standard’ coded sample using recognize. To do quick edit distance based search and replace to fix messy data, you can use turbo search and replace.

By keeping track of;
c

s2
we can calculate variance with; (s2/c) - (s/c)**2
Note: we have to clamp var
at zero. When working with small numbers, they sometimes end up -ve due to numerical instability.
It might be interesting to do a moving average implementation like: https://github.com/pete88b/data-science/blob/master/pytorch-things/calculating-variance.ipynb

Version Control Systems
Version control(VCS) is a system that records changes to a file or a set of files in a repository. In the programming world a version control system is very useful. Its very convenient to have a tool that keeps track of the changes we've made overtime in the lifecycle of our project, if ever we made a mistake in our code we could easily reset a file back to a version where it was working.
On top of all that a VCS is not just limited for programmers, writers, artists and basically anyone who uses a computer that makes changes to files can use this.
Having a version controll is also great for work that requires collaboration since everyone's changes are tracked and if we are to merge them all together we can do it easily using git.
Git - a distributed Version Control System
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. [^1]
Git is actually one of many version control systems out there, and what makes git different from other version control systems is that it's "distributed"
So what does distributed version control mean?
Version control systems have different types:
Local Version Control System
Many people’s version-control method of choice is to copy files into another directory (perhaps a time-stamped directory, if they’re clever). This approach is very common because it is so simple, but it is also incredibly error prone. It is easy to forget which directory you’re in and accidentally write to the wrong file or copy over files you don’t mean to.
To deal with this issue, programmers long ago developed local VCSs that had a simple database that kept all the changes to files under revision control.
defenition from git-cm
Image from git-scm.com
Centralized Version Control System
The next major issue that people encounter is that they need to collaborate with developers on other systems. To deal with this problem, Centralized Version Control Systems (CVCSs) were developed. These systems, such as CVS, Subversion, and Perforce, have a single server that contains all the versioned files, and a number of clients that check out files from that central place. For many years, this has been the standard for version control. defenition from git-cm
Image from git-scm.com
Distributed Version Control System
This is where Distributed Version Control Systems (DVCSs) step in. In a DVCS (such as Git, Mercurial, Bazaar or Darcs), clients don’t just check out the latest snapshot of the files: they fully mirror the repository. Thus if any server dies, and these systems were collaborating via it, any of the client repositories can be copied back up to the server to restore it. Every checkout is really a full backup of all the data.
defenition from git-cm

Configuring our git
We want git to recognize who we are, so let's configure it to do so by running the following commands in our terminal.
git config --global user.name "Your User Name" # this will set the username
git config --global user.email<EMAIL_ADDRESS># this will set your email address
git config --global actually just stores these configuration in a separate file in your home directory. You can view it by typing:
cat ~/.gitconfig
We can actually do looots of things with git config, but for now, let's just use it to add our email and username.
CONFIG BONUS Let's add pretty colors to our git <3
git config --global color.ui true
This will make our git interface have color syntax (e.g. red for lines removed and green for lines added)
Setting up SSH KEYS
In our hangouts I simply demonstrated a tutorial provided by Github. Please follow that link to learn how to generate SSH keys for your machine and add them to github. Alternatively you can download the client for your machine and this will automatically add ssh keys and add them to github.
Git timelines
Git creates a timeline for us that will contain time capsules or snapshots of our folder. The green marks below represent the snapshots. We will discuss what they are below
Basic Git Commands
git init
git init
initializes a git repository in whatever folder we're located in. It enables the folder we're in to be version controlled.
Without initializing git, we cannot run any git commands in our folder. Let's try it out.
git status #running git command in a folder is not git enabled
output: fatal: Not a git repository (or any of the parent directories): .git
git init # to initialize git
output: Initialized empty Git repository in /Users/shopify/test/.git/
git status
git status
displays if there's any differences between the current files we have and the last commit/snapshot that was in our repository. It also displays if there's anything currently staged in our repository.
git add
git add
adds files to our stage. Git add accepts a filename as an argument, or a wild card. We can do git add .
to add all the files. We can also pass it the name of the extension + a wild card so that it will add all the files with that extension git add ‘*.txt’
will add all the files that have txt
as an extension.
What is staged?
So let's imagine an actual stage, and snapshots as actual pictures. When we add new files to our stage they are not necessarily in a snapshot yet, just think that they're getting ready for a photoshoot and they're posing right now. When we take the picture it's the actual snapshot and the files that are in the stage are the only ones included in it.
git commit
git commit
records the changes or takes the "snapshot" of the files on the stage. git commit
accepts the option -m
and a message parameter that will serve as the title of the snapshot.
git commit -m "fixed the typo 'asdf' to 'qwerty'"
Tip: It's a good practice to pass short but detailed messages of what we did for the commit.
git remote
We used git remote
to connect with our github repo. Git remote allows us to add a remote repositorie from the cloud that will be connected to our current repository.
Usually it is best to keep our original repository in the cloud just in case something happens to our devices.
In the hangout we passed 3 parameters to git remote [action] [name-of-remote-repository] [url-of-the-repository]
Adding Repositories
action
- we can pass either add
or rm
to add or remove our remote repository.
name-of-repository
- here we will pass the name we would like to assign to our remote repository. It's common to name our remote cloud repository "origin".
url-of-the-repository
- We've used github to get the url of our repository.
Steps to get the remote url
- Navigate to http://github.com
- Go to the repository that you want to use, and get the SSH clone url
This is what our git command looks like
git remote add origin git@github.com:your-user-name/git-basics.git
Removing repositories
Removing remote repositories is easy. All we need to do is this: git remote rm [name-of-repository]
. That's it.
So if I want to remove origin
I will do git remote rm origin
.
Git push
Git push allows us to push
and copies our last changes into the remote repository that we created. The changes that are going to be copied are only the ones that are commited.
Git stash.
There may be times that we want git to remember the files we've added to the stage, but we also want to undo it and maybe try something else.
Git let's us stash
the files on our stage and keeps it, until we are ready to apply
it again.
Let's try it out.
First let's create 2 sample files
$ touch sample1.txt sample2.txt
Then let's add them to our stage.
$ git add sample1.txt sample2.txt
Let's check our status. We can see that we've added the files and that it's ready to be commited.
$ git status
> # Changes to be committed:
># (use "git reset HEAD <file>..." to unstage)
>#
># new file: sample1.txt
># new file: sample2.txt
>#
- Now let's do a
git stash
and check thestatus
. We can see that the files we created are gone.
$ git stash
> Saved working directory and index state WIP on gh-pages: 8741e43 fix date
> HEAD is now at 111111 fixing things
$ git status
> # On branch origin
> nothing to commit, working directory clean
In this step you guys free to add/change/modify any files.
Now let's do a
git stash apply
. Now we can see that the files have been added
$ git stash apply
># On branch gh-pages
># Changes to be committed:
># (use "git reset HEAD <file>..." to unstage)
>#
># new file: sample1.txt
># new file: sample2.txt
>#

MSG_GEN_FILE_SELECTOR_RESCAN, MSG_GEN_FILE_SELECTOR_SUSPEND, MSG_GEN_FILE_SELECTOR_END_SUSPEND
Each time the File Selector changes directories, it scans that directory and displays only the files it is supposed to. It looks into each file briefly to check the file against each criterion set in the File Selector. You can force the GenFileSelector to rescan the current directory with the message
MSG_GEN_FILE_SELECTOR_RESCAN
.
Occasionally you will want to scan the current directory only once after changing many parameters instead of rescanning after each change (search limitations, current volume, current selection, etc.). To optimize redrawing and rescanning, you can temporarily keep the GenFileSelector from scanning each time a
MSG_GEN_FILE_SELECTOR_SET_...
message is sent. To do this, send the following messages (both must be used, though not at the same time):
MSG_GEN_FILE_SELECTOR_SUSPEND
MSG_GEN_FILE_SELECTOR_END_SUSPEND
void MSG_GEN_FILE_SELECTOR_RESCAN();
This message causes the File Selector to rescan its current directory. The File Selector will re-build and re-display its entire file list. This message will only work when the File Selector is visible on the screen.
Source: Unrestricted.
Destination: Any GenFileSelector object that is on the screen.
Interception: Generally not intercepted.
Boolean MSG_GEN_FILE_SELECTOR_SUSPEND();
This message causes the File Selector to suspend directory scans until a
MSG_GEN_FILE_SELECTOR_END_SUSPEND
is received. This provides the ability to avoid unnecessary directory rescans when several different attributes are being changed in succession (e.g. volume, mask, and file types).
No user action is affected by this message; only the following attribute-setting messages will be affected (their normal automatic rescan will not happen). Note that all messages have the prefix
MSG_GEN_FILE_SELECTOR_
:
SET_SELECTION SET_FULL_SELECTION_PATH
In addition to the above messages, the
GenClass
message
MSG_GEN_PATH_SET
will also be suspended.
Source: Unrestricted.
Destination: Any non-suspended GenFileSelector object.
Parameters: None.
Return: An error flag:
true
if the File Selector is already suspended,
false
if the suspension is successful.
Interception: Generally not intercepted.
Warnings: After suspending a File Selector with this message, be sure to unsuspend it with
MSG_GEN_FILE_SELECTOR_END_SUSPEND
.
Boolean MSG_GEN_FILE_SELECTOR_END_SUSPEND();
This message unsuspends a File Selector that had previously been suspended with
MSG_GEN_FILE_SELECTOR_SUSPEND
. This message automatically causes a directory rescan. Because multiple suspension attempts are disallowed, this message only needs to be sent once to unsuspend the File Selector.
Source: Unrestricted.
Destination: Any suspended GenFileSelector object.
Parameters: None.
Return: An error flag:
true
if the File Selector was not previously suspended,
false
if the File Selector is successfully unsuspended.
Interception: Generally not intercepted.


We suggest Python, Go and C# for hot language in marcket
Python is an interpreted high-level general-purpose programming
language. Python's design philosophy emphasizes code readability with its notable
use of significant indentation. Its language constructs as well as its object-oriented
approach aim to help programmers write clear, logical code for small and large-scale
projects.
Python consistently ranks as one of the most popular programming languages.

Go is a statically typed, compiled programming language
designed at Google by Robert Griesemer, Rob Pike, and Ken Thompson. Go is
syntactically similar to C, but with memory safety, garbage collection,
structural typing, and CSP-style concurrency. The language is often referred to
as Golang because of its domain name, golang.org, but the proper name is Go.
C#C# (pronounced see sharp, like the musical note C♯, but
written with the number sign)[b] is a general-purpose, multi-paradigm programming
language encompassing static typing, strong typing, lexically scoped, imperative,
declarative, functional, generic, object-oriented (class-based), and component-oriented
programming disciplines.
We suggest JavaScript,C/C++ and Java for less coding
JavaScriptoften abbreviated as JS, is a programming language
that conforms to the ECMAScript specification. JavaScript is high-level,
often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax,
dynamic typing, prototype-based object-orientation, and first-class functions.
Alongside HTML and CSS, JavaScript is one of the core technologies of the World
Wide Web.[10] Over 97% of websites use it client-side for web page behavior,
often incorporating third-party libraries.[12] All major web browsers have a
dedicated JavaScript engine to execute the code on the user's device.

C/C++is a general-purpose programming language created by
Bjarne Stroustrup as an extension of the C programming language, or "C with Classes".
The language has expanded significantly over time, and modern C++ now has object-oriented,
generic, and functional features in addition to facilities for low-level memory
manipulation. It is almost always implemented as a compiled language, and many
vendors provide C++ compilers, including the Free Software Foundation, LLVM,
Microsoft, Intel, Oracle, and IBM, so it is available on many platforms.

JAVA is a high-level, class-based, object-oriented programming
language that is designed to have as few implementation dependencies as possible.
It is a general-purpose programming language intended to let application
developers write once, run anywhere (WORA),[16] meaning that compiled Java code
can run on all platforms that support Java without the need for recompilation.
Java applications are typically compiled to bytecode that can run on any Java
virtual machine (JVM) regardless of the underlying computer architecture.
The syntax of Java is similar to C and C++, but has fewer low-level facilities
than either of them. The Java runtime provides dynamic capabilities
(such as reflection and runtime code modification) that are typically not available
in traditional compiled languages. As of 2019, Java was one of the most popular
programming languages in use according to GitHub, particularly for client-server
web applications, with a reported 9 million developers.

For Back-end we suggest Ruby/Rails, SQL and MongoDB
Ruby on Rails, or Rails, is a server-side web application
framework written in Ruby under the MIT License. Rails is a model–view–controller
(MVC) framework, providing default structures for a database, a web service, and
web pages. It encourages and facilitates the use of web standards such as JSON or
XML for data transfer and HTML, CSS and JavaScript for user interfacing. In addition
to MVC, Rails emphasizes the use of other well-known software engineering patterns
and paradigms, including convention over configuration (CoC), don't repeat yourself
(DRY), and the active record pattern.

SQL(Structured Query Language) is a domain-specific language
used in programming and designed for managing data held in a relational database
management system (RDBMS), or for stream processing in a relational data stream
management system (RDSMS). It is particularly useful in handling structured data,
i.e. data incorporating relations among entities and variables.
SQL offers two main advantages over older read–write APIs such as ISAM or VSAM.
Firstly, it introduced the concept of accessing many records with one single
command. Secondly, it eliminates the need to specify how to reach a record,
e.g. with or without an index.

MongoDBMongoDB is a document database built on a scale-out architecture
that has become popular with developers of all kinds who are building scalable applications
using agile methodologies.
MongoDB was built for people who are building internet and business applications who
need to evolve quickly and scale elegantly. If you are doing that, you should consider
MongoDB.
For front-end we suggest React, Angular,PHP
React(also known as React.js orReactJS)
is an open-source front-end JavaScript library[3] for building user interfaces or
UI components. It is maintained by Facebook and a community of individual developers
and companies. React can be used as a base in the development of single-page or
mobile applications. However, React is only concerned with state management and
rendering that state to the DOM, so creating React applications usually requires
the use of additional libraries for routing, as well as certain client-side functionality.

Angular (commonly referred to as "Angular 2+" or "Angular v2
and above") is a TypeScript-based open-source web application framework led by
the Angular Team at Google and by a community of individuals and corporations.
Angular is a complete rewrite from the same team that built AngularJS.
Angular is used as the frontend of the MEAN stack, consisting of MongoDB database,
Express.js web application server framework, Angular itself (or AngularJS), and
Node.js server runtime environment.

PHPPHP is a general-purpose scripting language especially
suited to web development. It was originally created by Danish-Canadian
programmer Rasmus Lerdorf in 1994. The PHP reference implementation is now
produced by The PHP Group. PHP originally stood for Personal Home Page, but it
now stands for the recursive initialism PHP: Hypertext Preprocessor.

For limited time we suggest Swift
Swift is a general-purpose, multi-paradigm, compiled
programming language developed by Apple Inc. and the open-source community,
first released in 2014. Swift was developed as a replacement for Apple's earlier
programming language Objective-C, as Objective-C had been largely unchanged since
the early 1980s and lacked modern language features. Swift works with Apple's
Cocoa and Cocoa Touch frameworks, and a key aspect of Swift's design was the
ability to interoperate with the huge body of existing Objective-C code developed
for Apple products over the previous decades. It is built with the open source
LLVM compiler framework and has been included in Xcode since version 6, released
in 2014. On Apple platforms, it uses the Objective-C runtime library which allows
C, Objective-C, C++ and Swift code to run within one program.

If you execute the delete action from the Tapestry View you'll see that Loomy will actually figure out what Tapestry elements you're trying to delete and it will aggregate all it's file into this operation. So if for example you try to delete a page, Loomy will delete the page class, template and it's resource bundle. IntelliJ IDEA will then look for usages of all the resulting files and you'll be able to, as usual, go through with the operation or cancel it. |

One of the main tools used in autonomous mapping and navigation is a 3D Lidar. A 3D Lidar provides various advantages. It is not sensitive to light conditions, it can detect color through reflective channels, it has a complete 360 degree view of the environment and does not require any ”learning” to detect obstacles. One can use the reflective channel to detect the color of lanes as well as a regular 2D axis view to avoid obstacles. The pointcloud information from the Lidar can also easily enable mapping and localization as the vehicle will know where it is at all points. It is easy to see why so many large scale autonomous vehicle units invest in expensive and bulky Lidars. However, this is not accessible to all due to it’s price. A camera (even depth) is much more affordable. However, it comes with it’s own slew of disadvantages. It can see color but programming for the color is hard due to varying light conditions. Unless you use multiple cameras you often can’t see all around you. You must therefore work with lesser information. These factors together are a hindrance to autonomous mapping and navigation. We thus aim to resolve it through this project

In this section of the project, we are trying to create a map of an unknown environment so that the robot is able to know where it is at any point in time in this unknown environment
Click on the image to learn more
In this section we aim to be able to navigate autonomously. For that we use the images taken by the camera to find objects that need avoidance. We also use the lanes displayed by the image to stay within boundaries at all times

In this section, we aim to tune our camera to address its light sensitivity problems. Our tuning work involves both finding configurations that offset light intensity and use the best-tuned configuration to validate realtime performance

Camila Cabello Reveals The Most Rebellious Thing She's Ever Done
Camila Cabello heads into a super festive home after a workout at the gym in Los Angeles on Tuesday afternoon (November 19).
The 21-year-old singer was seen picking up a bite to eat and some juice after her workout before heading out for the day with her mom Sinuhe.
Speaking with Rolling Stone recently, Camila opened up about the most rebellious thing she’s ever done in her life and turns out, it happened while she was still in Fifth Harmony.
“When I was in the group [Fifth Harmony], me and one of the girls snuck into this club on the first floor of a hotel for a white party,” she revealed. “We were, like, 16 or something, and if we wanted to leave the room, we had to tell the tour manager so our security and our team at the time were looking for us. It’s not a great answer: The last rebellious thing I did was when I was 16 years old.”
However, it was a fun party.
Camila added, “It was fun because we weren’t allowed to be in it. But actually this is inspiring me!”

Attributes
The port on this target host of this service.
The range is 0-65535.
The priority of this target host.
A client MUST attempt to contact the target host with the lowest-numbered priority it can reach; target hosts with the same priority SHOULD be tried in an order defined by the weight field. The range is 0-65535. Note that it is not widely implemented and should be set to zero.
The domain name of the target host.
A target of “.” means that the service is decidedly not available at this domain.

The weight field specifies a relative weight for entries with the same priority. Larger weights SHOULD be given a proportionately higher probability of being selected. The range of this number is 0-65535. Domain administrators SHOULD use Weight 0 when there isn't any server selection to do, to make the RR easier to read for humans (less noisy). Note that it is not widely implemented and should be set to zero.
