And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me.
2 Corinthians 12:7
The devil has used the traditional teaching of Paul's thorn in the flesh to talk believers out of the blessings of God for years, to try to convince us to settle for everything from sickness to sin--and to do it of our own free will. It is perhaps the most destructive and the most widely accepted misinterpretation of Scripture that exists in the Body of Christ today. I've gone into countries to preach to people who hardly had any knowledge of the Word at all and still I have found that somehow they'd been taught about Paul's thorn.
And most of them have been taught wrongly. Tradition says that God gave Paul the thorn in the flesh. What's more, tradition makes the thorn into some great mystery. But the Scripture doesn't say that at all! It says that the thorn in the flesh was a messenger of Satan. Not God-- Satan! The thorn was quite literally just what Paul says it was--a "messenger sent from Satan." You see, everywhere Paul went, he preached the gospel and every time he preached, he destroyed a little more of Satan's kingdom. So, Satan sent a messenger, an evil spirit, to stop him.
When Paul sought the Lord concerning this thorn (look at 2 Corinthians 12:8-10), God didn't answer Paul in the negative. God said, "My grace (or, My favor) is enough. It is sufficient for you. For My strength is made perfect in your weakness (inability to produce results)" (W.E. Vine's Expository Dictionary).
In other words, when Paul didn't have enough human strength to overcome, God's miracle-working power was sufficient for him. It enabled him to be an overcomer in spite of his weakness.
 Throw tradition aside and dare to believe the Word of God. Fight the fight of faith, and just like the Apostle Paul, you will see the salvation of the Lord!

NDA convener should be appointed for better coordination: Chirag Paswan
Paswan, speaking to reporters after an NDA meeting ahead of the winter session of Parliament, said Shiv Sena's absence was felt at the meet as it was one of the oldest National Democratic Alliance member.
by PTIAn NDA convener should be appointed for better coordination among alliance partners, newly appointed Lok Jan Shakti party chief Chirag Paswan said on Sunday.
Paswan, speaking to reporters after an NDA meeting ahead of the winter session of Parliament, said Shiv Sena’s absence was felt at the meet as it was one of the oldest National Democratic Alliance member.
“There should be better coordination among allies and an NDA convener should be appointed,” he said.
It’s a matter of concern that the Telugu Desam Party left the alliance first and then the Rashtriya Lok Samata Party did.
“But all of us (allies) will work together in the upcoming session and more such meetings should happen,” said Paswan, who was appointed the LJP chief earlier this month.

JavaScript is my first love but the bulk of my paid work involves writing a lot of PHP for Joomla! CMS. Joomla! CMS is a powerful piece of software that is extendable through extensions. These extensions give you the powerful ability to turn the CMS into any application that tickles your fancy.
Building Joomla! extensions can be cumbersome because their architacture follows a strict MVC pattern. Once all the necessary files have been created you need to compress them into a zip file that is installable via the CMS backend.
Since I started using Gruntjs I have automated my development process in a number of ways that has greatly increased my productivity and eliminated some of the boring monotonous tasks.
These are the ways that I'm using Gruntjs to build Joomla! Extensions.
I am using grunt-init to automatically generate the base code and files for my extensions. I have created a grunt-init template that is copied to my project by simply openning my project directory from the commandline shell and running the command grunt-init my-extension-template
. This will prompt me for all the required metadata and then create my files.
I have also written a plugin that generates boilerplate code and files for my views, models, and controllers. All I need do is type the command and pass in the name of the new item, e.g grunt joomla:view
will prompt me for a name and then create all the view
files.
joomla: {
model: {
files: [
{tmpl: 'tmpl/com/model.tmpl', dest: 'com_mycomponent/site/models/<%= view %>.php'},
{tmpl: 'tmpl/com/table.tmpl', dest: 'com_mycomponent/site/models/tables/<%= view %>.php'}
]
},
view: {
files: [
{tmpl: 'tmpl/com/view.tmpl', dest: 'com_mycomponent/site/views/<%= view %>/view.html.php'},
{tmpl: 'tmpl/com/default.tmpl', dest: 'com_mycomponent/site/views/<%= view %>/tmpl/default.php'},
{tmpl: 'tmpl/com/xml.tmpl', dest: 'com_mycomponent/site/views/<%= view %>/tmpl/default.xml'}
]
},
controller: {
files: [
{tmpl: 'tmpl/com/controller.tmpl', dest: 'com_mycomponent/site/controllers/<%= view %>.php'}
]
}
}
JSHint is a JavaScript quality tool that helps to detect errors and potential problems in your JavaScript code. Visit the JSHint page to learn more.
jshint: {
all: [
'Gruntfile.js',
'com_mycomponent/*.js'
],
options: {
jshintrc: '.jshintrc'
}
}
When I'm writing code my commandline shell is always open and I find it easier to run most desktop operations from there. Instead of opening the file system to create compressed zip files for my extensions I simply run a Gruntjs task that generates that file for me. No more time wasted deleting files first and responding to pop up dialog boxes. For this task I use a plug in called compress.
compress: {
component: {
options: {
archive: "build/com_mycomponent.zip"
},
files: [
{cwd: 'com_mycomponent/', src: ['**/*'], expand: true, dest: ''},
]
}
}
Before I build a zipped file for extension I run JSHint to validate the JavaScript and I also run a PHP command that checks for syntanx errors in my php files. For this I use a plugin called grunt-exec. I have modified the original grunt-exec plugin so that I can pass a custom function to the child_process's data
event, you can checkout my pull request for this feature. If validation fails the process will exit.
exec: {
testphp: {
cmd: "find ./com_mycomponent -name '*.php' -exec php -l {} ;",
onOutData: function (data) {
console.log(data);
if (data.match(/Errors parsing|PHP Parse error/g)) {
process.exit(1);
}
},
onErrData: function (data) {
console.log(data);
if (data.match(/Errors parsing|PHP Parse error/g)) {
process.exit(1);
}
}
}
Now I don't have to leave the commandline to perform trivial tasks like compressing zip files. It feels awesome!


Citroen leaves world championship as Ogier exits
Citroen is leaving the world rally championship with immediate effect after six-times world champion Sebastien Ogier announced his departure from the team, the French manufacturer said on Wednesday.
REUTERS: Citroen is leaving the world rally championship with immediate effect after six-times world champion Sebastien Ogier announced his departure from the team, the French manufacturer said on Wednesday.
Citroen Racing said it had made the decision "due to the absence of a first-class driver available for (the) 2020 season."
The motorsport.com website said Ogier was expected to be announced as a Toyota driver on Monday.
Toyota's Estonian Ott Tanak won the driver's title in Spain last month, ending Ogier's six year reign, but announced four days later that he was joining Hyundai for 2020.
Hyundai secured the manufacturers' crown when this month's season-ending Australian race was called off due to the threat of bushfires.
"Our decision to withdraw from WRC programme as early as end of 2019 follows on Sebastien Ogier's choice to leave Citroen Racing," said Citroen CEO Linda Jackson.
"We obviously have not wished this situation but we could not imagine 2020 season without Sebastien."

Environments
Manage your module releases by dividing your site into environments.
Slice and Dice
Puppet lets you slice your site up into an arbitrary number of “environments” and serve a different set of modules to each one. This is usually used to manage releases of Puppet modules by testing them against scratch nodes before rolling them out completely, but it introduces a lot of other possibilities, like separating a DMZ environment, splitting coding duties among multiple sysadmins, or dividing the site by hardware type.
What an Environment Is
Every agent node is configured to have an environment, which is simply a short label specified in puppet.conf’s environment
setting. Whenever that node makes a request, the puppet master gets informed of its environment. (If you don’t specify an environment, the agent has the default “production” environment.)
The puppet master can then use that environment several ways:
- If the master’s
puppet.conf
file has a[config block]
for this agent’s environment, those settings will override the master’s normal settings when serving that agent. - If the values of any settings in
puppet.conf
reference the$environment
variable (likemodulepath = $confdir/environments/$environment/modules:$confdir/modules
, for example), the agent’s environment will be interpolated into them. - Depending on how
auth.conf
is configured, different requests might be allowed or denied. - The agent’s environment will also be accessible in Puppet manifests as the top-scope
$environment
variable.
In short: environments let the master tweak its own configuration on the fly, and offer a way to completely swap out the set of available modules for certain nodes.
Naming Environments
Environment names should only contain alphanumeric characters and underscores, and are case-sensitive.
There are four forbidden environment names:
main
master
agent
user
These names are already taken by the primary config blocks. If you are using Git branches for your environment names, this may mean you’ll need to rename the master branch to something like production
or stable
.
Caveats
Before you start, be aware that environments have some limitations, most of which are known bugs or vagaries of implementation rather than design choices.
- Puppet will only read the
modulepath
,manifest
,manifestdir
, andtemplatedir
settings from environment config blocks; other settings in any of these blocks will be ignored in favor of settings in the[master]
or[main]
blocks. (Issue 7497) - File serving only works well with environments if you’re only serving files from modules; if you’ve set up custom mount points in
fileserver.conf
, they won’t work in your custom environments. (Though hopefully you’re only serving files from modules anyway.) - Prior to Puppet 3, environments set by external node classifiers were not authoritative. If you are using Puppet 2.7 or earlier, you must set the environment in the agent node’s config file.
- Serving custom ruby code via pluginsync, including custom types, providers, facts and functions is not currently functional on a per-environment basis. You can still use custom ruby code to to extend puppet, but it should be identical for all environments. Non-identical custom code across modules can result in unpredictable behavior. See the following open issues for more information:
Configuring Environments on the Puppet Master
In puppet.conf
As mentioned above, puppet.conf
lets you use $environment
as a variable and create config blocks for environments.
# /etc/puppet/puppet.conf
[master]
modulepath = $confdir/environments/$environment/modules:$confdir/modules
manifest = $confdir/manifests/unknown_environment.pp
[production]
manifest = $confdir/manifests/site.pp
[dev]
manifest = $confdir/manifests/site.pp
In the [master]
block, this example dynamically sets the modulepath so Puppet will check a per-environment folder for a module before serving it from the main set. Note that this won’t complain about missing directories, so you can create the per-environment folders lazily as you need them.
The example also redirects requests for a non-existent environment to a different site manifest, which will log an error and fail compilation; this can keep typos or forgetfulness from silently causing odd configurations.
In auth.conf
path /
auth true
environment appdev
allow localhost, customapp.example.com
If you specify an environment in an auth.conf
ACL, it will only apply to requests in that environment. This can be useful for developing new applications that integrate with Puppet; the example above will leave normal requests functioning normally, but allow an app server to access everything via the HTTP API.
In Manifests
The $environment
variable should only rarely be necessary, but it’s there if you need it.
Configuring Environments for Agent Nodes
In an ENC
Your external node classifier can set an environment for a node by setting a value for the environment
key. In Puppet 3 and later, the environment set by the ENC will override the environment from the agent node’s config file. If no environment is provided by the ENC, the value from the node’s config file will be used.
Note: In Puppet 2.7 and earlier, ENC-set environments are not authoritative, and using them results in nodes using a mixture of two environments — the ENC environment wins during compilation, and the agent environment wins during file downloads. If you need to centrally control your nodes environments, you should upgrade to Puppet 3 as soon as is practical.
As a temporary workaround, you can manage nodes’ puppet.conf files with a template and set the environment based on the ENC’s value; this will allow nodes to use a consistent environment on their second (and subsequent) Puppet runs.
Note: If your puppet master is running Puppet 3 but was once running Puppet 2.6, its auth.conf file may be missing a rule required for ENC environments. Ensure that the following rule exists somewhere near the top of your auth.conf file:
# allow nodes to retrieve their own node definition path ~ ^/node/([^/]+)$ method find allow $1
Puppet masters which have only run 2.7 and later should already have this rule in their auth.conf files.
On the Agent Node
To set an environment agent-side, just specify the environment
setting in either the [agent]
or [main]
block of puppet.conf
.
[agent]
environment = dev
Note that in Puppet 3 and later, this value will only be used if the ENC does not override it.
As with any config setting, you can also temporarily set it with a command line option:
# puppet agent --environment dev
Compatibility Notes
Environments were introduced in Puppet 0.24.0.

Dense Graph - A graph with lots of edges.
"Dense graphs have many edges. But, wait! ⚠ I know what you must be thinking, how can you determine what qualifies as “many edges”? This is a little bit too subjective, right? ? I agree with you, so let’s quantify it a little bit:
Let’s find the maximum number of edges in a directed graph. If there are |V| nodes in a directed graph (in the example below, six nodes), that means that each node can have up to |v| connections (in the example below, six connections).
Why? Because each node could potentially connect with all other nodes and with itself (see “loop” below). Therefore, the maximum number of edges that the graph can have is |V|*|V| , which is the total number of nodes multiplied by the maximum number of connections that each node can have."
When the number of edges in the graph is close to the maximum number of edges, the graph is dense.
Sparse Graph - Few edges
When the number of edges in the graph is significantly fewer than the maximum number of edges, the graph is sparse.
Uses a class to define the neighbors as properties of each node.
class GraphNode {
constructor(val) {
this.val = val;
this.neighbors = [];
}
}
let a = new GraphNode("a");
let b = new GraphNode("b");
let c = new GraphNode("c");
let d = new GraphNode("d");
let e = new GraphNode("e");
let f = new GraphNode("f");
a.neighbors = [e, c, b];
c.neighbors = [b, d];
e.neighbors = [a];
f.neighbors = [e];
The row index will corespond to the source of an edge and the column index will correspond to the edges destination.
matrix[i][j]
may not be the same as
matrix[j][i]
matrix[x][x]
is true for
any nodelet matrix = [
| A | B | C | D | E | F | |
|---|---|---|---|---|---|---|
| A | [True, | True, | True, | False, | True, | False] |
| B | [False, | True, | False, | False, | False, | False] |
| C | [False, | True, | True, | True, | False, | False] |

Saracens Confirm They Will Not Appeal Fine Or Points Deduction
by Sean McMahonSaracens have confirmed that they will not seek a review of the decision of an independent disciplinary panel which resulted in the club being deducted 35 league points and fined £5,360,272.31.
The panel found that Saracens had breached Premiership salary cap regulations in the seasons 2016-17, 2017-18 and 2018-19. Specifically, the panel found that the club failed to disclose payment to players and exceeded the ceiling for payments to senior players in each of the three seasons.
This outcome was the result of a nine-month investigation.
Darren Childs, Chief Executive of Premiership Rugby, said: “We welcome Saracens’ decision to accept the verdict of the independent panel and are pleased the club has crucially reaffirmed its commitment to the Premiership Rugby Salary Cap.
“This is the right outcome for English club rugby. Bringing this process to a conclusion means that we can focus on working in partnership with all Clubs to continue to build a competitive and successful league.”
Nigel Wray, Saracens chairman, said: “We have made mistakes and so, with humility, we must accept these penalties. As a club, we will now pull together and meet the challenges that lie ahead.
“We confirm our commitment to the Salary Cap, and the underlying principle of a level playing field, and will continue to work transparently with Premiership Rugby in this regard.”
Saracens are now bottom of the Premiership table on -22 points.


I've decided to lay my pain to paper only because my miracle medicine is still illegal.
Before 1992, twelve doctors proved in a court of law that Cannabis was vital to their patient's medical care. The people representing NIDA and Health and Human Services still provide the seven living patients with an ongoing monthly supply through their pharmacy. The rest of us go to prison.  The plant does not take lives, and in some cases it can actually save a life: I know... because it saved mine.
Now, due to prohibition laws, I can go to prison any day for nothing more than using a plant that heals me.
Because my medicine, so vital to my health, is illegal, I have learned as much about the drug war and the inside of prison as is possible, considering I have never lived in one. I have made it my business to know because I could be arrested at any time for what I do: I must repeatedly ignore a bad law in order to stay alive and useful.
If I go to prison, I will exist in a cold concrete cell and my body will deteriorate. I will be deprived of marijuana, so my mind could sink into the small, cramped world of depression. But, my spirit is strong because of my years of use and I do what I have to do. So, never, ever believe a rumor that Kay killed herself. I am much too strong for that now.
I wasn't strong in my pre-marijuana life. I was very fragile. Depression is like a gray thread woven throughout my family, so I had a high chance of living with it.
I'd been kind of a loner, inside myself all my childhood years. I grew from a withdrawn child, one my mom labeled 'moody,' into a broken adult. By the time I turned twenty I was having rages, followed by lots of tears, followed by periods of silence, where I could not speak, could not eat, could not respond. I knew I was flawed, but had no understanding of what was happening.
By the time I sought help several years later, I weighed 75 pounds. Suicide had begun to dominate my thoughts. It seemed the only way to stop the horrible sadness. The early attempts were weak, using generic pills that made me vomit but did nothing to ease the pain.
My first real breakdown sent me on a seven year journey into hell. When I couldn't stop crying for several days straight, I landed in a psychologist's office and was given elavil, then switched to melaril. We knew it wasn't working when I failed at my next attempt. I took pills and laid in the tub, and when it didn't work, I dressed soaking wet and ran barefoot aimlessly for nearly an hour on the frozen February streets.
I came down with pneumonia, almost comatose despair, and was graduated to the heavy stuff, Lithium, Librium, all kinds of vicious chemicals. And the sadness grew worse and worse. I could see myself losing control, but I didn't know how to stop it. Neither did the doctors, but I had insurance, and they were willing, even eager, to experiment with expensive new drugs.
For seven years I tried to destroy myself. I hid in a closet and chopped my long hair off to the roots. I threw my beautiful paintings into the river. I slept too much or too little, cried too easily... and raged. And I faithfully, obediently took their pills day after hopeless day.
I became repulsed when touched and that really hurt my children. When I began smelling myself and washing numerous times a day, I withdrew further from everyone. When I went to see the shrink, I sat way across the room. When he found out why, I was admitted to the psych ward of an expensive hospital. I stayed for a month and began the perfectly legal 'Haldol drool'. This stuff 'drug' me down so deep, I couldn't even remember to swallow.
For seven years I let them try whatever they wanted. Every time they took me off another medicine to get ready for the next, I'd have withdrawal. Each drug has its own hell, and some would set my arms and legs to twitching; some made me vomit. Haldol, my nomination for devil drug, did something to my brain. For awhile, I could see the words of a book, but I could not make any sense of them.
For seven years I grew sicker and sicker. As they changed my medicine, all the old leftover medicine had gone into a shoebox in the top of the closet, but it was as if someone else had put it there: I never consciously thought about the pills, even as I stashed them. Then one night, without awareness, I slowly consumed all of them as I bathed the children, put them to bed and meticulously cleaned the house.
Through a series of extraordinary interventions, which included my mother 2000 miles away, her neighbor, my doctor, and ma bell, I did not die, but I came as close to success as I was ever going to get.
I vaguely remember a fireman, who had broken down the door to get into my home, walking me, dragging me, up and down the hallway. 'Wake up....stay awake,' he kept saying, but I retreated to nothingness.
The next memory I have is the blindingly brilliant emergency room, fighting to keep them from sticking the tubes into my nose and mouth. When I heard the ambulance driver say, 'Opps... There's lunch,' I gave up and sought sleep.
Three days later, I came back to the world at the sound of my doctor's voice asking the nurse, 'How long has she been like this?' My body was sitting up, alive, but my mind had been somewhere far away and quiet. He sat down beside the bed, and asked me simply, 'Why?' I could not speak and had no answer I was willing to share because I did not understand either.
He told me that he had saved me this time, but that next time I did this, the state was going to lock me in their very unhealthy mental ward. I numbly told him it didn't matter, because it was the truth. Nothing mattered.
For the few next years, I lived in a fog. I quietly played my mother role, but I was numb from medication, paralyzed by depression, just existing. I did what I had to do, but had lost hope that life would ever be more than bearable.
In 1977, when my 13 year old son drowned, the doctors asked me if I was a danger to myself. I told them that if a big Mack truck hit me, I could at least find out where my son was. So, they put me in the mental ward overnight.
I lay awake in the dark, hearing the moans and commotion of the disturbed people around me and their sounds were a reflection of the way I felt.
I went home and mechanically put together my son's funeral, but the essence of me was not there. I was 39 years old and I felt already dead.
After his cremation, an acquaintance handed me a joint and said, 'it might help and it certainly won't hurt'. Not only was I desperate, but I instinctively knew the truth. So, I sat out back alone on a stump and lit the marijuana.
I had taken only a couple of puffs and a humbling thing happened: I heard, felt, sensed a voice and it said, 'If you can handle this [my son's death], you will be able to handle anything that comes your way.'
...And my closed and shadowed mind opened like the petals of a flower and was flooded with sunshine. I had not realized how dark it was in there until marijuana turned on the light. I felt warm and at peace for the first time in my life. I felt strong and clean and whole and capable of dealing with whatever was before me. The feeling of total peace stayed with me for three days, the humbleness forever, and the strength continues to grow with everything I 'handle'.
I didn't know to call it medicine back then, but I took that shoebox full of perfectly legal and very dangerous drugs that had slowly refilled and buried it deep, deep in the earth near the lake. And I have, never, ever looked back. I thank God and His plant for the healing. He said everything I needed was here and He meant it.
I made plenty of mistakes, but I raised my five remaining children virtually as a single mother, and did hard decent work to support them. I stood strong during one daughter's three month coma, and helped birth six perfect grandchildren. At the age of 50, I managed three years in college, mastering four honors courses.
I did in-the-trenches research and learned about the lies, until I realized that I was supporting harmful policies with my silence. When the last child was no longer dependant on me, I began my own journey for justice. I, shy grandma that I was, stood in public places talking about 'politically unpopular' truths, debunking the myths, challenging authority, and comforting the people whose lives had been or could be altered and destroyed by marijuana laws. I devoted myself to the plant, its creator, and its people. Can you blame me?
I rejoice in living without doctors, without debilitating drugs, without the constant overwhelming depression. My mind is no longer filled with cobwebs and fog. My God, why would anyone want to take this from me?
What could motivate anyone to want to throw me back into that darkness and make me useless to others?
I just don't understand...

2019-20 Jaguar F-Type V6 recalled for being too noisy
Jaguar has been forced to recall 28 supercharged F-Type models, over concerns they don't meet Australia noise regulations.
by Scott Collie- shares
The 2020 Jaguar F-Type has been recalled due to models with the 3.0-litre supercharged V6 making too much noise.
It appears you can have too much of a good thing, because Jaguar says the "static noise level exceeds the regulated maximum decibel limit" in the F-Type V6.
A total of 28 cars are included in the campaign – a VIN list is attached here.
Jaguar will contact owners of the affected vehicles and advise them to organise a free 'fix' with their nearest dealership.
The original recall notice is attached here.

Hypertext Transfer Protocol (HTTP) is a protocol which allows the fetching of resources. It is the foundation of any data exchange on the Web and a client-server protocol.
The client is any tool that acts on the behalf of the user. This role is primarily performed by the Web browser. The browser is always the entity initiating the request.
On the opposite side of the communication channel, is the server which serves the document as requested by the client
Between the Web browser and the server, numerous computers and machines relay the HTTP messages. Due to the layered structure of the Web stack, most of these operate at either the transport, network or physical levels, becoming transparent at the HTTP layer. Those operating at the application layers are generally called proxies
The HTTP defines methods to indicate the desired action to be perfomed on the identified resource.

The Code Point Input Method is a simple input method that allows Unicode characters to be entered using their code point or code unit values.
The input method accepts three different notations, all using hexadecimal
digits from the set [0-9a-fA-F]:
While in composition mode, the user can use the left arrow, right arrow, backspace, and delete keys to edit the sequence. The "\u" or "\U" characters can only be deleted if they are not followed by hexadecimal digits in the composition sequence. Deleting the initial "\u" or "\U" returns the input method to pass-through mode.
Since the initial "\" character starts composition mode, a user must type two "\" characters in order to add a single "\" to the text. When an initial "\" has been entered, but the next character is not "u", "U", or "\", both the "\" and the subsequent character are committed, and the input method returns to pass-through mode. Also, typing a new line, or tab character at any time during composition immediately commits the current composed text.
Input methods are extensions to the Java Runtime Environment; they cannot be run as applications. Before you can use an input method, you have to install it in the JRE, run an application that supports input methods (such as the JFC demos Notepad and Stylepad), and select the input method. You can learn more about these steps from the article "Using Input Methods on the Java Platform" and more about supplementary character support from the article "Supplementary Characters in the Java Platform".
This input method requires JRE 5.0 or higher.

Liftpass is designed to sit on top of several existing and well developed technologies - making Liftpass very secure. That said, Liftpass has fundamentally two points where security must be looked at.
Authentication happens when the developer executes any API call. API requests are signed using HMAC as described in the API page. The user secret is used to sign the API request and should never be transmitted with the API request. If there is a belief that the secret has become known to an outsider, Liftpass can easily change the secret in the config.py
file as described in the settings page of the documentation.
Authentication also happens when the SDK communicates with Liftpass. Also using HMAC except this time the requests are signed using the application secret.
Using HMAC allows Liftpass and the SDK to know if the request has been tempered with while in transmission. Each request also contains the request URL and time which cannot be modified without breaking the signature. So API and SDK calls are procted from calls sent after the fact.
Although Liftpass can be run and interface directly with the outside world this is not recomended. Using a dedicated server such as Apache or NGinx will add an extra layer of security.
It is recommended that databases and filesystem resources be located within a virtual private network not accessible from the internet.

open class Base58
Base58 is a way to encode Bitcoin addresses (or arbitrary data) as alphanumeric strings.
Note that this is not the same base58 as used by Flickr, which you may find referenced around the Internet.
Satoshi explains: why base-58 instead of standard base-64 encoding?
However, note that the encoding/decoding runs in O(n²) time, so it is not useful for large data.
The basic idea of the encoding is to treat the data bytes as a large number represented using base-256 digits, convert the number to be represented using base-58 digits, preserve the exact number of leading zeros (which are otherwise lost during the mathematical operations on the numbers), and finally represent the resulting base-58 digits as alphanumeric ASCII characters.
NB: This class originally comes from the Apache licensed bitcoinj library. The original author of this code is the same as the original author of the R3 repository.

A class that represents a single row in a database table.
The objects returned by the database context are instances of this class or its subclasses. The class is KVC-compliant. It is not thread-safe for the most part, i.e. if methods of an BXDatabaseObject instance will be called from different threads the result is undefined and deadlocks are possible.
Retrieving cached values is thread safe. This could be useful in situations, where worker threads need access to the object's contents but the contents have been fetched earlier.

Values from the object's cache.
This method is thread-safe and doesn't cause a fault to fire.
| - (BXDatabaseContext *) databaseContext |
The database context to which this object is registered.
This method doesn't cause a fault to fire.
| - (void) didTurnIntoFault |
Callback for turning into a fault.
This method will be called if any of the object's fields is faulted.
| - (void) faultKey: | (NSString *) | aKey |
Fault the given key.
The object's cached value or related object will be released. A new fetch won't be performed until any of the object's values is requested.

| - (BOOL) isDeleted |
Whether the object has beed deleted or is going to be deleted in the next commit.
This method doesn't cause a fault to fire.
|

Test object equality.
Currently objects are considered equal if they are managed by the same database context and their object IDs are equal. This method doesn't cause a fault to fire.
| - (int) isFaultKey: | (NSString *) | aKey |
Whether the given key is faulted or not.
This method doesn't cause a fault to fire.
| aKey | An NSString. May be nil, in which case the object is considered a fault if value for any of its keys is not cached. |
| - (BOOL) isInserted |
Whether the object has been inserted to the database in a previous transaction.
If the object has been deleted, this method returns YES. This method doesn't cause a fault to fire.
| - (BOOL) isLockedForKey: | (NSString *) | aKey |
Whether the given key is locked locked or not.
Returns YES if modifying the given key would block. Current implementation locks the whole object when any key gets locked. This method doesn't cause a fault to fire.
| - (id) objectForKey: | (BXAttributeDescription *) | aKey |
Value or objects from the database.
Look up the value from cache or ask the database context to fetch it. Currently this method calls primitiveValueForKey:.
| aKey | A BXAttributeDescription. |

| aKey | An NSString. |
| - (void) setPrimitiveValuesForKeysWithDictionary: | (NSDictionary *) | aDict |
Set multiple values.
This is not merely a convenience method; invoking this is potentially much faster than repeatedly using setPrimitiveValue:forKey:. However, for foreign keys, setPrimitiveValue:forKey: should be used instead or the collection proxy be modified directly.
| - (id< BXObjectStatusInfo >) statusInfo |
A proxy for monitoring the object's status.
Returns a proxy that can be used with BXObjectStatusToEditableTransformer and BXObjectStatusToColorTransformer. This method doesn't cause a fault to fire.
| - (BOOL) validateForDelete: | (NSError **) | outError |
Determines whether the receiver can be deleted in its current state.
Currently, only inverse relationships' delete rules are checked. This method could cause a fault to fire.
| - (BOOL) validateValue: | (id *) | ioValue | |
| forKey: | (NSString *) | key | |
| error: | (NSError **) | outError | |
Validate a value.
Currently, only null constraints are checked. This method doesn't cause a fault to fire.

Morphine is a website blocker with a twist. Instead of allotting a certain amount of time each day for using blocked sites, Morphine gives you a "balance" to pull from, which is very slowly filled with minutes.  In other words: Regulated Distraction™®!
But why take this approach? Well, let's say you're at work and have a standard website blocker turned on.  However if you were using Morphine, your wait would be no more than 10 minutes (by default), since the balance is always slowly being added to.
Ready to get started? Using the balance is very easy. Once you've set the options below to your taste, click on the Morphine icon in the toolbar or try to visit a blocked site. A page with a few large buttons with numbers will be displayed—these represent minutes. Click one to add that number to the "meter". Once the meter is used up, the sites will return to being blocked.
Set the optimal time balance charge rate for you! With the default settings, +1 minute will be given every 10 minutes, but it can be adjusted for optimal productivity, distraction, and attention span levels.
Add sites to block and (optionally) allow, one per line. Subdomains and subpaths are accepted, and if not provided will be wildcarded.
The allowed sites override the blocked sites and can be used to allow specific subdomains or subpaths.
Examples: reddit.com
, plus.google.com
, google.com/analytics/web
Having a problem with Morphine? Send all angry emails to<EMAIL_ADDRESS>and don't forget to have a nice day!
If you're a developer and would like to contribute, awesome! Morphine is open source, and can be found on GitHub.
I'm a 15 year old web & game developer who loves making beautiful, useful, and fun things. Like this extension? Check out my other stuff!

Electromagnetism is the branch of physics that deals with the electromagnetic force(EMF) that occurs between electrically charged particles. The EMF exhibits electromagnetic fields such as magnetic and electric fields.. Hans Christian Oersted discovered the relation between electricity and magnetism(electromagnetism) of how a electric current creates a magnetic field.
Electron Configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. When configuring a element, the coefficient represents the shell number(starting from the inner shells) and the exponents on the variable represents the number of electrons in that sub-shell. The variables represent their designated section on the periodic table. They are s, p, d, f, they hold 2 electrons(1 Orbital), 6 electrons(3 Orbitals), 10 electrons(5 Orbitals), and 14 electrons(7 Orbitals) respectively.
To determine the configuration of an atom with multiple electrons, we follow the Aufbau Principle, which is a rule that states that electrons fill atomic orbitals of the lowest available energy levels before occupying the higher levels.
If the elctrons are unpaired, then there is magnetism. The arrows represent the direction the electrons spin(up arrows are spinning the same way), and a pair of electrons spin in different directions. According to the Pauli Exclusion Principle, each orbital can only hold a maximum of two electrons with opposite spins. If an orbital has 2 electrons, the electrons start filling in other higher-energy orbitals. Keep in mind if an atom is magnetic, that doesn't mean that the whole element is magnetic.
According to Hund's Rule, every orbital in a subshell gets one electron before any orbitals get two electrons and those single electrons will have the same spin.
For instance, Nitrogen will have 3 individual arrows pointing in the same direction rather than have a pair of electrons in the p subshell; this element is paramagnetic(has any unpaired electrons) meaning it is weakly attracted to external applied magnetic fields.
There is also a shortcut to finding the electron configuration of an element: you group all of the blocks and list the subshells in order and cross a diagonal arrow through them to indicate the order you go in, then count and solve the for the electron configuration. The answer can also be written in a short form where the previous noble gas on the periodic table is in place for some of the subshells and then list the remaining ones:
When electrons move, it creates a magnetic field and becomes a temporary magnet; this is an electromagnet. If the current used to create the electromagnet is DC, then it will have a fixed magnetic flux density and a fixed orientation of poles. Whereas if you use AC, it will have a varying magnetic flux density and alternating poles. The strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it.
To generate electricity, you have to spin a magnet near a coil to attract/repel the electrons to create a current to then produce electricity. Hydro, Wind, Nuclear, and many more find efficient ways to make a magnet spin to produce energy.
Electric Currents are produced in wire loops when there is any change in the magnetic flux passing through the wire loop; this current is known as induced current. If either object moves, current is produced. Whereas, if both objects are stationary, there is no current in the wire.
As magnetic flux increases, the current travels clockwise in the wire. As magnetic flux decreases, current travels counterclockwise in the wire. To describe the electric field induced by a moving magnet, we can use a left-hand rule, where the thumb represents the direction of the magnet's motion and the fingers represent the electric field(forces on the positive charges).
Faraday's Law states that the induced voltage is equal to the negative change in magnetic flux over a unit of time. There is a negative sign because the Electromagnetic Force(induced voltage) always opposes any change in the magnetic flux; this is Lenz's Law.
When you snap a magnet in half, nothing about the magnetic field really changes. The two halves will attract each other's broken ends and will be able to stick back together again. A big magnet is made of many tiny magnets(with north and south poles) called magnetic domains. So if you cut a magnet in half, the newly cut faces will become the new north or south poles of the smaller pieces.

java.lang.Object anl.repast.gis.display.RepastMapMouseInterpreter
public class RepastMapMouseInterpreter
The StandardMapMouseInterpreter is a basic implementation of the MapMouseInterpreter, working with an OMGraphicHandlerLayer to handle MouseEvents on it. This class allows the OMGraphicHandlerLayer, which implements the GestureResponsePolicy, to not have to deal with MouseEvents and the OMGraphicList, but to just react to the meanings of the user's gestures.
The StandardMapMouseInterpreter uses highlighing to indicate that mouse movement is occuring over an OMGraphic, and gives the layer three ways to react to that movement. After finding out if the OMGraphic is highlightable, the SMMI will tell the layer to highlight the OMGraphic (which usually means to call select() on it), provide a tool tip string for the OMGraphic, and provide a string to use on the InformationDelegator info line. The layer can reply or ignore any and all of these notifications, depending on how it's supposed to act.
For left mouse clicks, the SMMI uses selection as a notification that the user is choosing an OMGraphic, and that the OMGraphic should be prepared to be moved, modified or deleted. For a single OMGraphic, this is usually handled by handing the OMGraphic off to the OMDrawingTool. However the GestureResponsPolicy handles the situation where the selection is of multiple OMGraphics, and the layer should prepare to handle those situations as movment or deletion notifications. This usually means to change the OMGraphic's display to indicate that the OMGraphics have been selected. Selection notifications can come in series, and the GestureResponsePolicy is expected to keep track of which OMGraphics it has been told are selected. Deselection notifications may come as well, or other action notifications such as cut or copy may arrive. For cut and copy notifications, the OMGraphics should be removed from any selection list. For pastings, the OMGraphics should be added to the selection list.
For right mouse clicks, the layer will be provided with a JPopupMenu to use to populate with options for actions over a OMGraphic or over the map.
The StandardMapMouseInterpreter uses a timer to pace how mouse movement actions are responded to. Highlight reactions only occur after the mouse has paused over the map for the timer interval, so the application doesn't try to respond to constantly changing mouse locations. You can disable this delay by setting the timer interval to zero.

While the cultivated gardens are showing off their palette of colors, so are the plants growing in our Natural Area. As you hike on the Natural Area's five miles of trails, take time to appreciate Mother Nature's garden of flowers all around.
You'll find this beautiful white flower growing in the really rocky areas on the tops of hills.
These five-petaled pink flowers dot the hillside for several weeks every spring.
This native in the aster family (Asteraceae), is a sign that spring has definitely arrived. When you come across this beauty, be sure to smell its sunflower-like inflorescence. It smells just like chocolate!
Reaching several feet tall, this perennial attracts a variety of pollinators including wasps, bees, beetles, and butterflies.
Soft yellow flowers cover this important foothill shrub. It is a major food source for Mule Deer.
Often confused with Arrowleaf Balsamroot, you can tell it apart from its cousin by looking at the leaves. Mules-ear leaves are almost elliptical, while Arrowleaf Balsamroot leaves are arrow-shaped.
From its poisonous bulb, this spring beauty sends up stiff green leaves, followed by delicate white flowers.
After your hike through the Natural Area, don't forget to meander through our cultivated gardens to take in the beauty our Red Butte horticulturists work so hard to make happen.

HELLO WORLD
Hi,nice to meet you.You have found an unique and excellent page.
Name: Emmy
Ocupation: a high school student who you may see everyday
feeling right know:ummmmm, a little bit embarrasse to madke my first websit
also , i have no idea about what to talk about
i like making emoji
almost all teacher who taught me can't flee that destiny(laughing)
she is my physic teacher
this picture is taken when she was teaching us Fleming left hand's rule
our math teacher
to be honest, this is the clearest emoji i had


Hi! I am Qing Yi and I am 20 years old this year. I graduated from Chong Hwa High School(居銮中华中学), which is one of the Malaysia chinese independent highschools.
I have many hobbies (such as playing games,watching anime,learning japanese,etc). But the one I enjoyed most is playing suona(唢呐) within a chinese-instrumental ensemble.
I am currently in the DigFab Program which provides me opportunities to learn something excitingly new and fun. Frankly saying, I think all that credit to the thought of participating EA trial out. I'm really honoured to be selected as one of the EA members. I'm looking forward to improve myself inside EA and learn more interesting stuffs!


How to find a path between two points in the maze. Base Algorithm review for "Open Labyrinth" Checkio mission.
Early I've written an article about solutions and algorithms for mission "Open Labyrinth" for CheckiO blog. But readers asked about more schemas and interactive explanation. And I made this page with labyrinth algorithm explanations. You can see how BFS, DFS or A* queue or stack and how they find a path for various labyrinths.
All examples are based on original "Open Labyrinth" mission. In this mission you are given the map of a maze, and your task is to find a path from one corner to another. The maze can be represented as a graph where empty cells are nodes and adjacent cells are connected. Because we don't need find the shortest path, we can use various graph-traversal algorithms.
First I would like to change a representation for a maze. This part is not necessary and we can detect "neighbours" while search path. But for newbies it will be simpler to decompose the problem and first convert a maze as 2D array to a graph as a dictionary.
Our graph will be represented as a dictionary, where keys are node coordinates and values are neighbour node coordinates and direction how to get in it. Node coordinates are represented as a tuple with two numbers. This way each cell has unique name. Directions will be useful to write route when we will search a path inside the maze.
First we collect all empty cells and write them as a keys. Then gather information about neighbours. Of course we can do this in one iteration through a matrix with defaultdict, for example, but I want to show it with simpler for python newbie way. For each cell we look ar "south" and "east" neighbours only and add them as "connections". And with these "S" and "E" directions we add reverse "N" and "W" connection for neighbour cells. This way we will skip duplicate operations. Don't forget to check edge cases. And as result we will get our maze to graph convertor. Below you can see simple code for it.
def maze2graph(maze): height = len(maze) width = len(maze[0]) if height else 0 graph = {(i, j): [] for j in range(width) for i in range(height) if not maze[i][j]} for row, col in graph.keys(): if row < height - 1 and not maze[row + 1][col]: graph[(row, col)].append(("S", (row + 1, col))) graph[(row + 1, col)].append(("N", (row, col))) if col < width - 1 and not maze[row][col + 1]: graph[(row, col)].append(("E", (row, col + 1))) graph[(row, col + 1)].append(("W", (row, col))) return graph
In these animation you can see how the recent function check neighbours. But it's little difficult from Python realisation because py dictionary are unordered. But this animation should show you how maze change to "skeleton" form.
Breadth-first search (BFS) is an algorithm for traversing or searching a path in a graph. It starts at some arbitrary node of the graph and explores the neighbor nodes first, before moving to the next level neighbors. For BFS we are using queue to store nodes which will be exploring. This way we check the nearest nodes first. For tree it looks like we look level by level and before "to down" at the next level we should check all nodes in current level. For graph search it's very important to write all visited nodes or we can get to a loop.
BFS is an optimal and it is guaranteed to find the best solution that exists. Time complexity for BFS is O(|V|+|E|), where |V| is a number of nodes and |E| is a number of edges in the graph.
In Python we can use "deque" as queue or simple list (but it's slower). We put the initial node to the queue. Then repeat the next procedure until visit the goal node or visit all available nodes: take the first from the queue, check was it visited or not, check is it goal, put all neighbours in the end of the queue, repeat. For each step we track not only nodes, but directions and a path to the current node too.
from collections import deque def find_path_bfs(maze): start, goal = (1, 1), (len(maze) - 2, len(maze[0]) - 2) queue = deque([("", start)]) visited = set() graph = maze2graph(maze) while queue: path, current = queue.popleft() if current == goal: return path if current in visited: continue visited.add(current) for direction, neighbour in graph[current]: queue.append((path + direction, neighbour)) return "NO WAY!"
In the next animation you can see how BFS traverse through a maze. Numbered cells are nodes in the queue (we take with the lowest number). Grey cells are visited. Orange cells show the result route.
Depth-first search (DFS) is an algorithm similar to BFS. It starts at some arbitrary node of the graph as BFS, but explores as far as possible along each branch. For DFS non-recursive implementation we are using stack instead queue as in BFS to store nodes which will be exploring. This way we check nodes first which were added in stack last.
DFS is not an optimal and it is not guaranteed to find the best solution that exists. So DFS is not good choice to find a path in a maze, but it has another applications as finding connected components or maze generation.
Python code for DFS has only one difference from BFS "queue" to "stack" renaming (for readability) and "popleft()" to "pop()".
from collections import deque def find_path_dfs(maze): start, goal = (1, 1), (len(maze) - 2, len(maze[0]) - 2) stack = deque([("", start)]) visited = set() graph = maze2graph(maze) while stack: path, current = stack.pop() if current == goal: return path if current in visited: continue visited.add(current) for direction, neighbour in graph[current]: stack.append((path + direction, neighbour)) return "NO WAY!"
In the next animation you can see how DFS traverse through a maze. As we can see for the empty cell DFS works well, but not for "Snake and Short". Numbered cells are nodes in the queue (we take with the highest number). Grey cells are visited. Orange cells show the result route.
A* widely used pathfinding algorithm and it's an extension of Edsger Dijkstra's 1959 algorithm. A* uses a greedy search and finds a least-cost path from a given initial node to one goal node (out of one or more possible goals). As A* traverses the graph, it follows a path of the lowest expected total cost or distance, keeping a sorted priority queue of alternate path segments along the way. It uses a heuristic cost function of node to determine the order in which the search visits nodes in the graph. For A* we take first node which have the lowest sum of path cost and expected remaining cost. But heuristic must be admissible, that is, it must not overestimate the distance to the goal. The time complexity of A* depends on the heuristic.
For python we can use "heapq" module for priority queue and add cost part for each element. For maze one of the simple heuristic can be manhattan distance.
from heapq import heappop, heappush def heuristic(cell, goal): return abs(cell[0] - goal[0]) + abs(cell[1] - goal[1]) def find_path_astar(maze): start, goal = (1, 1), (len(maze) - 2, len(maze[0]) - 2) pr_queue = [] heappush((0 + heuristic(start, goal), "", start)) visited = set() graph = maze2graph(maze) while pr_queue: cost, path, current = heappop(pr_queue) if current == goal: return path if current in visited: continue visited.add(current) for direction, neighbour in graph[current]: heappush((cost + heuristic(neighbour, goal), path + direction, neighbour)) return "NO WAY!"
In the next animation you can see how A* traverse through a maze. As we can see this algorithm find the shortest path and expand less cells than BFS. Numbered cells are nodes in the priority queue (as they was added, but not as will taken). Grey cells are visited. Orange cells show the result route.


Sikhs celebrate founder's 550th birthday in smog-hit northern India
SULTANPUR LODHI, India: Sporting saffron and blue turbans and headscarves, hundreds of thousands of devotees braved hazardous smog to pack the city of Sultanpur Lodhi in India for the 550th birth celebrations of Sikhism's founder Guru Nanak.
Guru Nanak, born in 1469 to a Hindu family in a present-day Pakistani city east of Lahore, is believed to have gained enlightenment in Sultanpur Lodhi in the northern Indian state of Punjab, making it one of the key pilgrimage sites for the religion.
People rode on tractors, motorbikes and in cars - and some even walked barefoot - to reach the Sri Ber Sahib temple, or gurudwara, where they honoured the Guru with prayers.
Others took a dip in a pond on the temple's premises believed to contain holy water with healing powers.
"I'm feeling very blessed to be here. To be with our first guru. I think our first Guru is still present here," Sukhjeet Singh, a Sikh devotee at the gurudwara in Sultanpur Lodhi, told AFP.
"My whole being has been soaked in this spiritual situation. It's a very momentous occasion."
The religion's holiest shrine, the Golden Temple in Punjab's Amritsar some 70km from Sultanpur Lodhi, was lined with lights to mark the occasion.
Across India, Sikh and Hindu communities prepared feasts known as langars to mark the anniversary. Food is distributed to the community, including the poor.
This year's celebrations took on special significance due to the opening of the Kartarpur Corridor --a secure land link allowing Indian Sikhs to visit the gurdwara in the Pakistani town where Guru Nanak died.
Guru Nanak was the first of ten gurus who developed the Sikh faith and community over the next centuries.
There are now more than 20 million Sikhs worldwide, with the vast majority in India.
