Justin Bieber looks pretty pleased with himself doing wheelies on electric bike
Justin Bieber must have the biggest garage on earth for all his gadgets, the latest being a fancy electric bicycle.
The Purpose star, 25, popped a wheelie on the motorised push bike while out and about in Beverly Hills – and looked pretty pleased with himself that he managed to pull off the stunt.
Justin punched the air and grinned at the waiting photographers as he pulled off the trick despite the bike’s heavy-looking wheels and bodywork.
He was keeping himself amused while his new wife, Hailey Baldwin, is in Germany for work, and it looked like his new toy was definitely curing the boredom.
An electric bike like the one Justin was riding retails around £1,000 and can get up to 25km (15.5miles) an hour.
Justin and Hailey had their second wedding ceremony in September for their friends and family after having tied the knot at a New York courthouse a year earlier.

As well as riding around on his new toy, Justin was also seen heading to the studio in Los Angeles as well as the dermatologist to deal with a breakout.

Justin has always been a big fan of a fancy car (or seven), and has owned Ferraris, a Batmobile-inspired Cadillac, a leopard-print Audi and even a Smart car (hey, everyone knows street parking in LA can be tight).
He’s also had some less practical vehicles in the form of Can-Am Spyder motorbike which he was once filmed riding on a pavement and narrowly missing pedestrians, and quad bike or two.
While his car insurance must be through the roof for this vast amount of high-performance supercars, at least he can afford it…

Darren Cauthon is a programmer who has lived two dev careers. His first career was wasted away as a timid dark-matter developer. He stayed there until he was introduced to a simple idea: The idea that it's possible to write code that works with test driven development. Since then he's become a vocal advocate for clean, tested code, a regular contributor to open-source, a speaker, a mentor, an instructor, and has written dozens of applications in different languages. He's a passionate programmer who doesn't understand why all programmers are not swept away by their passion for programming. Darren lives in Kansas with his family.


UpdatePolicy
attribute
Use the UpdatePolicy
attribute to specify how AWS CloudFormation handles updates to the
following resources:
Resource update policies
-
For
AWS::AppStream::Fleet
resource, CloudFormation can update your Image Builder with newer AppStream 2.0 agent software. For more information see, Manage AppStream 2.0 Versions. -
For
AWS::AutoScaling::AutoScalingGroup
resources, CloudFormation invokes one of three update policies depending on the type of change you make or whether a scheduled operation is associated with the Auto Scaling group.-
The
AutoScalingReplacingUpdate
andAutoScalingRollingUpdate
policies apply only when you complete one or more of the following:-
Change the Auto Scaling group's
AWS::AutoScaling::LaunchConfiguration
. -
Change the Auto Scaling group's
VPCZoneIdentifier
property. -
Change the Auto Scaling group's
LaunchTemplate
property. -
Update an Auto Scaling group that contains instances that don't match the current
LaunchConfiguration
.
If both the
AutoScalingReplacingUpdate
andAutoScalingRollingUpdate
policies are specified, setting theWillReplace
property totrue
givesAutoScalingReplacingUpdate
precedence. -
-
The
AutoScalingScheduledAction
policy applies when you update a stack that includes an Auto Scaling group with an associated scheduled action.
-
-
For
AWS::ElastiCache::ReplicationGroup
resources, CloudFormation can modify a replication group's shards by adding or removing shards, rather than replacing the entire resource. For more information, see UseOnlineResharding policy. -
For
AWS::OpenSearchService::Domain
and legacyAWS::Elasticsearch::Domain
resources, CloudFormation can upgrade an OpenSearch Service domain to a new version of OpenSearch or Elasticsearch without replacing the entire resource. For more information, see EnableVersionUpgrade policy. -
For
AWS::Lambda::Alias
resources, CloudFormation performs an CodeDeploy deployment when the version changes on the alias. For more information, see CodeDeployLambdaAlias Update policy.
AppStream 2.0 update policy
AppStream 2.0 configuration for an update policy.
Syntax
JSON
{ "UpdatePolicy": { "StopBeforeUpdate": { "Type": "
Boolean
" }, "StartAfterUpdate": { "Type": "Boolean
" } } }
YAML
UpdatePolicy: StopBeforeUpdate: Type:
Boolean
StartAfterUpdate: Type:Boolean
AutoScalingReplacing update policy
To specify how AWS CloudFormation handles replacement updates for an Auto Scaling group, use the
AutoScalingReplacingUpdate
policy. This policy enables you to specify whether
AWS CloudFormation replaces an Auto Scaling group with a new one or replaces only the instances in the Auto Scaling
group.
Before attempting an update, ensure that you have sufficient Amazon EC2 capacity for both your old and new Auto Scaling groups.
Syntax
JSON
"UpdatePolicy" : { "AutoScalingReplacingUpdate" : { "WillReplace" :
Boolean
} }
YAML
UpdatePolicy: AutoScalingReplacingUpdate: WillReplace:
Boolean
Properties
WillReplace
-
Specifies whether an Auto Scaling group and the instances it contains are replaced during an update. During replacement, CloudFormation retains the old group until it finishes creating the new one. If the update fails, CloudFormation can roll back to the old Auto Scaling group and delete the new Auto Scaling group.
While CloudFormation creates the new group, it doesn't detach or attach any instances. After successfully creating the new Auto Scaling group, CloudFormation deletes the old Auto Scaling group during the cleanup process.
When you set the
WillReplace
parameter, remember to specify a matchingCreationPolicy
. If the minimum number of instances (specified by theMinSuccessfulInstancesPercent
property) don't signal success within theTimeout
period (specified in theCreationPolicy
policy), the replacement update fails and AWS CloudFormation rolls back to the old Auto Scaling group.Type: Boolean
Required: No
AutoScalingRollingUpdate policy
To specify how CloudFormation handles rolling updates for an Auto Scaling group, use the
AutoScalingRollingUpdate
policy. Rolling updates enable you to specify whether
AWS CloudFormation updates instances that are in an Auto Scaling group in batches or all at once.
During a rolling update, some Auto Scaling processes might make changes to the Auto Scaling group before
CloudFormation completes the rolling update. These changes might cause the rolling update to
fail. To prevent Auto Scaling from running processes during a rolling update, use the
SuspendProcesses
property. For more information, see What are some recommended best practices for performing Auto Scaling group rolling
updates?
Be aware that, during stack update rollback operations, CloudFormation uses the
UpdatePolicy
configuration specified in the template before the current stack
update operation. For example, suppose you have updated the MaxBatchSize
in your
stack template's UpdatePolicy
from 1 to 10. You then perform a stack update, and
that update fails and CloudFormation initiates an update rollback operation. In such a case,
CloudFormation will use 1 as the maximum batch size, rather than 10. For this reason, we recommend
you make changes to the UpdatePolicy
configuration in a stack update separate
from and before any updates to the AWS::AutoScaling::AutoScalingGroup
resource
that are likely to initiate rolling updates.
Syntax
JSON
"UpdatePolicy" : { "AutoScalingRollingUpdate" : { "MaxBatchSize" :
Integer
, "MinInstancesInService" :Integer
, "MinSuccessfulInstancesPercent" :Integer
, "PauseTime" :String
, "SuspendProcesses" : [List of processes
], "WaitOnResourceSignals" :Boolean
} }
YAML
UpdatePolicy: AutoScalingRollingUpdate: MaxBatchSize:
Integer
MinInstancesInService:Integer
MinSuccessfulInstancesPercent:Integer
PauseTime:String
SuspendProcesses: -List of processes
WaitOnResourceSignals:Boolean
Properties
MaxBatchSize
-
Specifies the maximum number of instances that CloudFormation updates.
Default:
1
Maximum:
100
Type: Integer
Required: No
MinInstancesInService
-
Specifies the minimum number of instances that must be in service within the Auto Scaling group while CloudFormation updates old instances. This value must be less than the MaxSize of the Auto Scaling group.
Default:
0
Type: Integer
Required: No
MinSuccessfulInstancesPercent
-
Specifies the percentage of instances in an Auto Scaling rolling update that must signal success for an update to succeed. You can specify a value from
0
to100
. CloudFormation rounds to the nearest tenth of a percent. For example, if you update five instances with a minimum successful percentage of50
, three instances must signal success.If an instance doesn't send a signal within the time specified in the
PauseTime
property, CloudFormation assumes that the instance wasn't updated.If you specify this property, you must also enable the
WaitOnResourceSignals
andPauseTime
properties.The
MinSuccessfulInstancesPercent
parameter applies only to instances only for signaling purpose. To specify the number of instances in your autoscaling group, see theMinSize
,MaxSize
, andDesiredCapacity
properties for the AWS::AutoScaling::AutoScalingGroup resource.Default:
100
Type: Integer
Required: No
Important When the
MinSuccessfulInstancesPercent
property is set to0
, CloudFormation waits for 0% of the capacity instances to be in anInService
state.MinSuccessfulInstancesPercent
returns immediately and before considering the Auto Scaling group status asUpdate Complete
to move on to the subsequent resources defined in the stack template.If other Auto Scaling groups are defined in your CloudFormation template, they will update simultaneously. When all Auto Scaling groups are deployed at once with 0% of the capacity instances in an
InService
state, then you will experience availability issues, due to 0 instances serving customer traffic.CloudFormation recommends that
MinSuccessfulInstancesPercent
is set to a value greater than 0, allowing reasonable minimum instances to verify before considering an Auto Scaling groups update to be completed. PauseTime
-
The amount of time that CloudFormation pauses after making a change to a batch of instances to give those instances time to start software applications. For example, you might need to specify
PauseTime
when scaling up the number of instances in an Auto Scaling group.If you enable the
WaitOnResourceSignals
property,PauseTime
is the amount of time that CloudFormation should wait for the Auto Scaling group to receive the required number of valid signals from added or replaced instances. If thePauseTime
is exceeded before the Auto Scaling group receives the required number of signals, the update fails. For best results, specify a time period that gives your applications sufficient time to get started. If the update needs to be rolled back, a shortPauseTime
can cause the rollback to fail.Specify
PauseTime
in the ISO8601 duration format(in the format PT
, where each#
H#
M#
S#
is the number of hours, minutes, and seconds, respectively). The maximumPauseTime
is one hour (PT1H
).Default:
PT0S
(0 seconds). If theWaitOnResourceSignals
property is set totrue
, the default isPT5M
.Type: String
Required: No
SuspendProcesses
-
Specifies the Auto Scaling processes to suspend during a stack update. Suspending processes prevents Auto Scaling from interfering with a stack update. For example, you can suspend alarming so that Amazon EC2 Auto Scaling doesn't initiate scaling policies associated with an alarm. For valid values, see the
ScalingProcesses.member.N
parameter for the SuspendProcesses action in the Amazon EC2 Auto Scaling API Reference.Default: Not specified
Type: List of Auto Scaling processes
Required: No
WaitOnResourceSignals
-
Specifies whether the Auto Scaling group waits on signals from new instances during an update. Use this property to ensure that instances have completed installing and configuring applications before the Auto Scaling group update proceeds. AWS CloudFormation suspends the update of an Auto Scaling group after new EC2 instances are launched into the group. AWS CloudFormation must receive a signal from each new instance within the specified
PauseTime
before continuing the update. To signal the Auto Scaling group, use the cfn-signal helper script orSignalResource
API.To have instances wait for an Elastic Load Balancing health check before they signal success, add a health-check verification by using the cfn-init helper script. For an example, see the
verify_instance_health
command in the Auto Scaling rolling updatessample template. Default:
false
Type: Boolean
Required: Conditional. If you specify the
MinSuccessfulInstancesPercent
property, you must also enable theWaitOnResourceSignals
andPauseTime
properties.
AutoScalingScheduledAction policy
To specify how AWS CloudFormation handles updates for the MinSize
, MaxSize
,
and DesiredCapacity
properties when the
AWS::AutoScaling::AutoScalingGroup
resource has an associated scheduled action,
use the AutoScalingScheduledAction
policy.
With scheduled actions, the group size properties of an Auto Scaling group can change at any time.
When you update a stack with an Auto Scaling group and scheduled action, CloudFormation always sets the
group size property values of your Auto Scaling group to the values that are defined in the
AWS::AutoScaling::AutoScalingGroup
resource of your template, even if a
scheduled action is in effect.
If you don't want CloudFormation to change any of the group size property values when you have
a scheduled action in effect, use the AutoScalingScheduledAction
update policy
and set IgnoreUnmodifiedGroupSizeProperties
to true
to prevent
CloudFormation from changing the MinSize
, MaxSize
, or
DesiredCapacity
properties unless you have modified these values in your
template.
Syntax
JSON
"UpdatePolicy" : { "AutoScalingScheduledAction" : { "IgnoreUnmodifiedGroupSizeProperties" :
Boolean
} }
YAML
UpdatePolicy: AutoScalingScheduledAction: IgnoreUnmodifiedGroupSizeProperties:
Boolean
Properties
IgnoreUnmodifiedGroupSizeProperties
-
If
true
, AWS CloudFormation ignores differences in group size properties between your current Auto Scaling group and the Auto Scaling group described in theAWS::AutoScaling::AutoScalingGroup
resource of your template during a stack update. If you modify any of the group size property values in your template, AWS CloudFormation uses the modified values and updates your Auto Scaling group.Default:
false
Type: Boolean
Required: No
UseOnlineResharding policy
To modify a replication group's shards by adding or removing shards, rather than replacing
the entire AWS::ElastiCache::ReplicationGroup resource, use the
UseOnlineResharding
update policy.
If UseOnlineResharding
is set to true
, you can update the
NumNodeGroups
and NodeGroupConfiguration
properties of the
AWS::ElastiCache::ReplicationGroup
resource, and CloudFormation will update those
properties without interruption. When UseOnlineResharding
is set to
false
, or not specified, updating the NumNodeGroups
and
NodeGroupConfiguration
properties results in CloudFormation replacing the entire
AWS::ElastiCache::ReplicationGroup
resource.
The UseOnlineResharding
update policy has no properties.
Things to consider when setting the UseOnlineResharding
update policy to
true
:
-
We strongly recommend you perform updates to the
NumNodeGroups
andNodeGroupConfiguration
properties as the only updates in a given stack update operation.Updating the node group configuration of a replication group is a resource-intensive operation. If a stack update fails, CloudFormation doesn't roll back changes to the node group configuration of a replication group. However, CloudFormation will roll back any other properties that were changed as part of the failed update operation.
-
Any node group updates require identifying all node groups.
If you specify the
NodeGroupConfiguration
property, you must also specify the NodeGroupId for each node group configuration in order for CloudFormation to update the number of nodes without interruption.When creating a replication group, if you don't specify an ID for each node group, ElastiCache automatically generates an ID for each node group. To update the replication group without interruption, use the ElastiCache console (https://console.aws.amazon.com/elasticache/
) or DescribeReplicationGroups to retrieve the IDs for all node groups in the replication group. Then specify the ID for each node group in your stack template before attempting to add or remove shards. Note As a best practice, when you create a replication group in a stack template, include an ID for each node group you specify.
In addition, updating the number of nodes without interruption requires that you have accurately specified the
PrimaryAvailabilityZone
,ReplicaAvailabilityZones
, andReplicaCount
properties for eachNodeGroupConfiguration
as well. Again, you can use the ElastiCache console (https://console.aws.amazon.com/elasticache/) or DescribeReplicationGroups to retrieve the actual values for each node group and compare them to the values in your stack template. You can update the property values of the node groups as a separate stack update, or as part of the same stack update that changes the number of node groups. When you use an
UseOnlineResharding
update policy to update the number of node groups without interruption, ElastiCache evenly distributes the keyspaces between the specified number of slots. This can't be updated later. Therefore, after updating the number of node groups in this way, you should remove the value specified for theSlots
property of eachNodeGroupConfiguration
from the stack template, as it no longer reflects the actual values in each node group. -
Actual node group removal results may vary.
When you specify a
NumNodeGroups
value that's less than the current number of node groups, CloudFormation instructs ElastiCache to remove as many node groups as necessary to reach the specified number of nodes. However, ElastiCache may not always be able to remove the desired number of node groups. In the event ElastiCache can't remove the desired number of node groups, CloudFormation generates a stack event alerting you to this. In cases where ElastiCache can't remove any node groups, the CloudFormation resource update fails.
For more information on modifying replication groups, see ModifyReplicationGroupShardConfiguration in the Amazon ElastiCache API Reference.
Syntax
JSON
"UpdatePolicy" : { "UseOnlineResharding" :
Boolean
}
YAML
UpdatePolicy: UseOnlineResharding:
Boolean
EnableVersionUpgrade policy
To upgrade an OpenSearch Service domain to a new version of OpenSearch or Elasticsearch rather than
replacing the entire AWS::OpenSearchService::Domain or AWS::Elasticsearch::Domain resource, use the EnableVersionUpgrade
update policy.
If EnableVersionUpgrade
is set to true
, you can update the
EngineVersion
property of the AWS::OpenSearchService::Domain
resource (or the ElasticsearchVersion
property of the legacy
AWS::Elasticsearch::Domain
resource), and CloudFormation will update that property
without interruption. When EnableVersionUpgrade
is set to false
, or
not specified, updating the EngineVersion
or ElasticsearchVersion
property results in CloudFormation replacing the entire
AWS::OpenSearchService::Domain
/AWS::Elasticsearch::Domain
resource.
The EnableVersionUpgrade
update policy has no properties.
For more information about upgrading OpenSearch Service domains, see UpgradeDomain in the Amazon OpenSearch Service Developer Guide.

CodeDeployLambdaAlias Update policy
To perform an CodeDeploy deployment when the version changes on an
AWS::Lambda::Alias
resource, use the CodeDeployLambdaAliasUpdate
update policy.
Syntax

resource, see Lambda alias update policy.
Examples
The following examples show how to add an update policy to an Auto Scaling group and how to maintain availability when updating metadata.
Add an UpdatePolicy
to an Auto Scaling group
The following example shows how to add an update policy. During an update, the Auto Scaling
group updates instances in batches of two and keeps a minimum of one instance in service.
Because the WaitOnResourceSignals
flag is set, the Auto Scaling group waits for new
instances that are added to the group. The new instances must signal the Auto Scaling group before
it updates the next batch of instances.

AutoScalingReplacingUpdate policy
The following example declares a policy that forces an associated Auto Scaling group to be
replaced during an update. For the update to succeed, a percentage of instances (specified
by the MinSuccessfulPercentParameter
parameter) must signal success within the
Timeout
period.
JSON
"UpdatePolicy" : { "AutoScalingReplacingUpdate" : { "WillReplace" : "true" } }, "CreationPolicy" : { "ResourceSignal" : { "Count" : { "Ref" : "ResourceSignalsOnCreate"}, "Timeout" : "PT10M" }, "AutoScalingCreationPolicy" : { "MinSuccessfulInstancesPercent" : { "Ref" : "MinSuccessfulPercentParameter" } } }

Maintain availability when updating the metadata for the cfn-init helper script
When you install software applications on your instances, you might use the AWS::CloudFormation::Init
metadata key and the cfn-init
helper script to bootstrap the instances in your
Auto Scaling group. CloudFormation installs the packages, runs the commands, and performs other
bootstrapping actions described in the metadata.
When you update only the metadata (for example, when updating a package to another
version), you can use the cfn-hup
helper daemon to detect and apply the updates. However, the
cfn-hup
daemon runs independently on each instance. If the daemon
happens to runs at the same time on all instances, your application or service might be
unavailable during the update. To guarantee availability, you can force a rolling update so
that CloudFormation updates your instances one batch at a time.
Forcing a rolling update requires CloudFormation to create a new instance and then delete the old one. Any information stored on the old instance is lost.
To force a rolling update, change the logical ID of the launch configuration resource, and then update the stack and any references pointing to the original logic ID (such as the associated Auto Scaling group). CloudFormation triggers a rolling update on the Auto Scaling group, replacing all instances.
Original template

Lambda alias update policy
The following example specifies the UpdatePolicy
attribute for an
AWS::Lambda::Alias
resource. All the details for the deployment are defined
by the application and deployment group that are passed into the policy.

Why settle for reality when you can dream up more?
Long-time life insurance industry leader loses customer base, prepares for reorganization
Insurance Overtime Ltd., one of the oldest industry players and the first to reach life-long, mass-market appeal, made a less-than-surprising announcement concerning reorganization, internal shifts and potential lay-offs.
Full business analysis and CEO interview in = date('F', mktime(0, 0, 0, date('m')+1, 1, date('y'))); ?> edition of HZ Magazine.
There are companies that provide notable instant gratification and eternal salvation. Simply put, we just can’t compete with that, not with our current offering.
We are proceeding to vote on some of our core beliefs and hope to mold the reality to our liking through the democratic process.

I never came to believe in the Easter Bunny, occasionally also known as Easter Hare or Spring Bunny, but in these times it did come as no surprise to actually find her legendary nest hiding under the century-old porcupine tree in my grandparents’ backyard garden.
After initial inquiries made by my paper, the Easter Bunny was hesitant to schedule for an interview, reportedly for a multitude of professional and personal reasons. After some persistent editorial work and persuasion, however, here I stand, slightly crouched in what I can only describe as a reception room of the mighty complex of living space, storage areas and grand aisles that constitute the nest of the Easter Bunny.
When asked about the usual disbelief and confusion surrounding his existence, or common misconceptions concerning his personality and traits, the Easter Bunny shows maturity but also slight displeasure.
– As an immortal being who has existed as long as reality itself has been here for us, I have grown used to the suspicion and hostility of mere mortals. Still, I sometimes think of the dreams I had as an infant about growing up as a respected guardian of lesser creatures. They really turned out to be as childish as you’d expect from a bunny just a couple of million of years old.
Some suppositions are, of course, more innocent than others. Most rarely lead to any serious harm or higher level of enforcement of Easter Bunny’s personal security measures.
– It is common for people to mistake me as male even though my apparent lack of penis is clearly visible in the vast majority of contemporary visual depictions. Younger humans might think I’m actually composed of chocolate myself, and, of course, there are still those who refuse to accept my existence altogether.
The Easter Bunny feels that even the less serious misconceptions about her are contributing to the harmful long-term trend of humans not accepting the world as it is. According to her, humans would not want to experience the world without the Easter Bunny, but their reluctance to recognize her existence, let alone her numerous contributions to our society, might eventually have undesirable implications.
– Shit sucks, man.
Shit sucking does not stop this resiliant supernatural hare from trying, though.
– With the relatively new hobby of delivering chocolate treats and other cool shit to people, the public opinion has started to show signs of permanent shift to a more positive tone. But this is true to only the western part of the world, and within that the level of acceptance varies greatly.
She remains hopeful: one can only imagine the amount of dedication that lies within this wonderful hare. After millenia of trying, one would expect slightly more acknowledgements for this oversized chocolate-bearing rabbit. Maybe one day we will wake up in a place where our superiors are met with acceptance and respect instead of suspicion and disbelief.
Malicious impersonators The Easter Bunny knows how to deal with people who try to take advantage of her status.
A shocking Editorial investigation series by Zachary San
Consumer interest in second-hand organs is increasing. It has been increasing, steadily, for the past century as medical science has developed rapidly.
But as we enter the 21st century, things seem to take an exponential turn for the worse. There’s no going back anymore: our culture expects us to give out our organs, and we expect to receive those of others. We are all organ thieves.
Is your family safe from supervillains?
Bad Enough Dudes Urban protection service
The society we live in is sick. I could save this as the shocking ending sentence of this text, but the truth is, that’s just the tip of the iceberg: the things I have to say about this whole collectivity of human interaction and cultural expectations is so corrupt, ugly and depraved, it takes substantial, constant effort for me to avoid vomiting uncontrollably all over the tacky interior of this larger-than-necessary hotel room initially cleaned for me by underage hotel employees, exploited daily in ways we in the West are unabe to even dream up.
In Part I of this series, originally published in the January edition of HZ Magazine, I wrote about the expectations and reservations I had about travelling to present-day Cambodia in search for the most notorious human organ bandit group known to western authorities. This highly organized mob – called the Tooth Fairy and commonly referred to simply as “She” – has grown to close to mythical proportions in both reputation and cash revenue.
The reservations I was talking about? I willfully threw out the window the whole idea of me even having a right to acknowledge the existence of such. The situation is far too dire to justify me being anxious, apprehensive or anything the like about entering this third-world country plagued by this mystic but obviously powerful criminal organization. We all know crime is rampant in most parts of the world, and no one cares about me or whatever goes on in my unanalytical half of the brain.
So, to the actual descriptive part of this text: the legends are true, to put it frankly. All of them, actually. I don’t mean to sound cruel, but the point of this tone I’ve set for the whole text is to deliver the description of how Cambodian Tooth Fairy actually shamelessly exploits countless families when you’ve all heard the stories before.
 People have been fucked with so thoroughly for so long that everyone has zero trust left for anyone other than themselves. Not that it stops the government, the Tooth Fairy or other organizations from keeping up the propaganda. Just look at this visualization of the Tooth Fairy:
She might give a penny or two to those who willfully support her in her exploits, but there are millions, even billions to be made in international organ trafficking, both legal and illegal. The legality is actually gray area here, as teeth that appear legal in paper might actually come from highly questionable sources in developing countries.
The Tooth Fairy is running the market when it comes to blood tooth trafficking. In the next part, I will hopefully have had the chance to write a coherent text of the disturbing notions made by my first Cambodian anonymous contact on the inside.
Biography of the fattest, fastest & most exploitive manipulative bastard in the arctic region by Enoch Temür
There’s this mystery man called Claus, Santa Claus. He naturally has multiple aliases, but that’s how he seems to be referred to in the most recent official documents. We have all heard stories and gathered half a dozen factoids, but few have an understanding of the whole story. We’re here to tell you.
First of all, it appears that, since at least recent times, Santa doesn’t act alone: he has an accomplice. Mrs. Claus is said to play an important part in maintaining order within their oppressed slave midget workforce. She apparently handles information structure and databases as well, seeing as the married couple maintains a vast database of all children in the world.
 That’s deeply disturbing, not only illegal in more or less every juristiction in the world. Santa’s dirty routine includes delivering these innocent boys and girls huge bags of presents (in quite an intriguing fashion, one might add – although that’s another issue entirely), sometimes even with the concent of their parents, thus gathering positive publicity and turning the popular opinion to his advantage.
Santa’s criminal record is long and extensive, but it appears that his most elaborate and dangerous schemes are yet to be seen.
Throughout history, Santa has switched both his look and location like no-one else in an elaborate effort to evade and deceive whoever might be after him. Originally from pre-Christian Western Europe, he has since moved to the more arctic and secluded regions of the world. In the recent times he is known to dwell in both the Finnish Lapland and the North Pole during the winter, while spending extravagant summer holidays on warm and sunny beaches of all continents.
Although all this has been globally known and well documented for years, a lot of the cunning criminal efforts of this indubitably bright mind remain in the dark: animal rights activists have long been gathering evidence – albeit with little success – of Santa’s illegal reindeer mass-farming activities, and it is still not entirely clear exactly how he amassed his army of 900 000 slave midgets without alarming the authorities.
But amass he did. Forced to wear demeaning children’s novelty clothes during their 18-hour shifts, these poor dudes are really pushed to their limits. Even the UN has taken action to offer some relief to the situation, but all actions of all authorities have so far yielded all but zero results. Santa is still at large, living well.
Ho Ho Ho The Santa Claus is known for his insatiable desire for prostitutes, up to three at a time. Just look at that egocentric grin and facial hair labeling him as a dirty, disgusting old man. Also, those glasses are fake and are only meant to mislead the authorities.
Tough dude claimed to exist in alternate reality: kills babies for revenge, amusement
A shocking real-life tale full of sick twists and mindfuck has started to unfold in the twilight zone of our reality and a reportedly alternate one called Heaven. While the exact details of these mysterious events are still being unwrapped by the investigative authorities, experts are calling the case “puzzling” and “fucking bizarre”.
The central focus point of the whole affair appears to be the mind-bending journal written by numerous followers, relatives and self-proclaimed successors of a really hardcore badass dude called God who, according to himself, “created the universe, time and all that can be counted under reality and existence” in just under a week, reportedly laying back doing some heavy drinking on the seventh day. Some of these nutbags also claim allegiance to his son, Jesus, originally conceived and raised under questionable circumstances in this weird family and environment.
As the apparent inability of the social workers to remedy the alarming situation labeled by careless child-raising, drug use, mental disorders, incest and homicidal activities continued to go on unnoticed, the disturbing cult continued to expand, touching the whole extended family and others in the region. While the teachings of the family grew increasingly bizarre and the hallucinations began to reach their focal point, federal authorities stepped in to remedy the situation.
It was too late, however.  This did not stop his followers to claim that he was actually raised from the dead by his father, leading to the creation of a horrible, hallucinating carpenter zombie creature. Eww.
And so the folklore starts to be formed. The son was a carpenter but apparently dad disapproved of this, preferring his son to take over the leadership of a weird cult instead. God was rarely seen – understandable, given he exists in a magical alternate universe – but still managed to maintain a strong control over his family and followers over telepathy.
And overtake he did, the son. He started perform weird, poorly staged and badly executed stunts which he himself labeled as miracles. Anyone could see that he was a shitty illusionist, but with clever camera angles and creative viral marketing, people who never saw him act his stuff out live and only heard occasional reports of him, at best, would eventually get it into their head that Jesus was as badass as his father was claimed to be.
Some people, for example, believe that he could chop one fish to small enough pieces to feed thousands of people without a laser cutter. Ha ha ha, oh wow.
It seems that God was supposed to be father of everyone, but still impregnated Jesus’ mother. While modern medical science explains that there remains a remote possibility of this being achievable (only) in theory, it is widely agreed to be totally unfeasible and blatantly untrue. This might provide some insight into why Jesus was so weird. Also, the mother still claims she is a virgin despite numerous eye witness accounts made public by sensationalist Middle-Eastern talk shows.
 She has continued her efforts to remedy her reputation and that of her relatives, but it seems she might be labeled as an incestive crack whore for the rest of her natural life. Maybe God will take her in his “arms” after that, or ensure that her natural life is prolonged to unnatural lengths, if he really is such a world-class magician.
Whatever the truth about Jesus’ mother, it remains quite irrelevant when looking at the big picture. For example, the scope in which God claims to have carried out infractions of privacy is simply astonishing – while he may not be telling the complete story, experts agree that there is most certainly some truth to this relentless bragging: God says he can read everyone’s mind whenever he wants, no matter how much foil you might have wrapped around your head, and that he routinely (although unpredictably) trolls innocent people by arranging stupid stunts that reflect their thoughts.
It remains to be seen whether God and his posse can actually get away with these stunts. This is not even all of it, or even close: child-murdering, kidnapping, raising the dead... these are the kind of things we’re dealing with here. One thing is for certain, however: authorities are not resting until they are brought to justice (or killed). FBI’s recent announcement has made this perfectly clear.
“I have zero respect for these fuckers, and I will personally guarantee that each of them will get a bullet in their head.” Ok, pretty harsh, maybe, but it’s not like God, Jesus’ or the whole “wholy trinity” didn’t have it coming.

The most important thing to remember is to never say anything that can be disputed, let alone disproved outright. Your propositions should stay on a very broad level of abstraction so that they are easy to accept as generally true – but when you use them in very spesific contexts, it is easy for untrained minds to accept them as explanations.
And, well, that’s it basically. Don’t forget the accompanying image and caption. Do what you do best and prevail.

“Man the falls!”
This order was given by one of the officers as the boat containing the rescued actor came close to the ship’s side. The sailors stood ready to hoist the boat to the davits again, when the tackle blocks should have been made fast by the hooks to the ring bolts at bow and stern.
“Best chance I ever had to get a rescue picture,” remarked Russ, as he reeled away at the film.
The young operator even managed to get in a favorable position, and take views as the blocks were being made fast to the boat. Then, as it was hoisted up, he pictured that.
“Is he all right?” asked Mr. Pertell of the sailors in the boat, when the craft was raised to the level of the rail.
“Aye, aye, sir,” answered the steersman. “Only a bit wet.”
But Mr. Towne was more than a bit wet. He was completely soaked, and a more bedraggled-looking specimen of humanity would be hard to find.
“Oh, the poor man!” exclaimed Ruth, who had thought better of her determination to go below.
“It’s his own fault,” snapped Miss Pennington. “He should not have carried on so.”
“Well, it was partly our fault,” interposed Miss Dixon, who was perhaps more just. “We were laughing with him.”
“Don’t go too close!” cautioned Miss Pennington, as she saw her friend advancing toward the group of sailors, and others who surrounded the rescue party. They were helping Mr. Towne out of the boat.
“Why shouldn’t I go close?” Laura wanted to know.
“You might get your dress wet. Mine spots terribly.”
“Oh, so does mine. I forgot; and sea water stains so badly!”
So the two actresses drew away.
“There, I guess that will do,” remarked Russ, as he saw that there was no more film left in the camera. “Now, Mr. Pertell, you’ll have to get some story written around these scenes. Add more to them, and you’ll have a good reel.”
“I’ll do it, Russ. I’m glad you were here to take them, so long as it did not turn out seriously.”
“Do you—er—ah—mean to say that you filmed me?” demanded the dudish actor, who had overheard this colloquy.
“I got some pictures of you—yes,” admitted Russ. “I couldn’t resist the temptation.”
“I demand that those pictures be destroyed!” cried Mr. Towne, who seemed to have recovered rapidly from his unexpected bath.
“What for?” asked Mr. Pertell, in surprise. “I haven’t seen them, of course—can’t until they’re developed, and that won’t be for some time. But I should say the rescue pictures would make a fine film.”
“But I want it burned up. I won’t have it shown!” insisted Mr. Towne.
“Why not?”
“Do you suppose for one instant—er, ah—that I am going to let the public see me like this?” and Mr. Towne glanced at his wet and dripping garments—garments that, but a short time ago, had been a walking testimonial of the tailor’s art. Now they were wet and misshapen.
“Why, you can’t expect a man who has just been rescued from New York Bay to look as though he came out of a band-box; can you, dear man?” asked Mr. Pertell. “Of course you look wet—the public will expect to see you wet—dripping with water, in fact. Water always comes out well in the movies, anyhow. Of course the public wants to see you wet!”
“But I don’t want them to!” protested the actor. “I have never been shown in pictures except when I was well dressed, and I do not propose to begin now.
“Oh, you are too fussy!” laughed Mr. Pertell. “Those pictures will have to go. The scene was too good to spoil, as long as you were not drowned.”
“I was in no danger of drowning,” returned Mr. Towne, coldly. “I am a good swimmer. I was taken by surprise, that is all.”
“Well, it made good pictures,” declared the manager, indifferently.
“Too bad I couldn’t get you just as you went overboard!” sighed Russ. “I was taken by surprise, too; but I did the best I could. We can have you do that part over.”
“Never!” cried Mr. Towne, angrily. “I will never be seen in an undignified position again, nor in clothes that have not been freshly pressed,” and he stalked away toward his stateroom.
“I can sympathize with you, my dear fellow,” murmured Mr. Bunn, who was as careful of his dignity, in a way, as was the other.  “I have had to play fireman, and ride in donkey carts, slide down hill and all such foolishness—all to the great detriment of my dignity.”
“Yes, this moving picture business is horrid,” agreed Mr. Towne, who was dripping water at every step. “But what is a chap to do? I tried the other sort of drama—on the stage, you know; but I did not seem to have the temperament for it.”
“Ah, would that I were back again, treading the boards in my beloved Shakespeare, instead of in this miserable moving picture acting,” sighed the tragedian.
The excitement caused by the mishap to Mr. Towne soon subsided. The steamer got on her way again, once the small boat had been hoisted up, and several tugs and motor craft that had gathered to give aid, if needed, went on their courses.
“Well, that’s something for a start,” remarked Alice, as she walked the deck with Ruth.
“Yes, I knew something would happen,” spoke Mr. Sneed, gloomily. “I felt it coming.”
“How could you?” asked Paul, winking at Russ.
“Because to-day is Friday. Something always happens on Friday.”
“Yes, we generally have fish for dinner,” remarked Russ, with a twinkle in his eyes.
“You may laugh,” sneered the gloomy actor, “but the day is not over yet. I am sure that something else will happen. The ship may sink before it gets to Florida.”
“Oh!” cried Ruth.
“Don’t be silly!” laughed Alice, while Russ gave Mr. Sneed a meaning look and remarked in a low voice:
“That’s enough of such talk, old man. It gets on the girls’ nerves. Why can’t you be cheerful?”
“I never amon Friday,” grumbled Mr. Sneed.
“No, and on very few other days,” commented Russ, as he went below to take the film out of his camera in readiness to ship it back to New York for development.
Ruth and Alice had done much traveling with their father when he was engaged in the legitimate drama, for he was with a number of road companies, that went from place to place. Water journeys were, however, rather a novelty to them, and now that the excitement of the rescue was over they went about the ship, looking at the various sights.
The Tarsus was not a big vessel, but it was a new and substantial craft engaged in the coast trade. A fairly large passenger list was carried and, as this was the winter season, many tourists were heading for the sunny South - the warm beaches of the coast, or the interior where the palms waved their graceful branches in the orange-scented breezes.
“How is your throat, Daddy?” asked Ruth, as Mr. DeVere joined his daughters in a stroll about the deck.
“Much better, I think,” he said. His voice was always hoarse now, totally unlike the vibrant tones in which he was used to speak his lines. “The pain seems less. I have hopes that the warm air of Florida may improve, and even cure it, in connection with the medicine I am taking.”
“Oh, wouldn’t that be just great!” cried Alice, as she clasped her arms about his neck. “Perhaps you could go back to the real theaters then, Daddy.”
“I might,” he replied with a smile at her; “but I do not know that I would. I am beginning to like this silent ‘drama.’ It is a rest from the hard work we old actors used to have to do. There is much less strain. And if I went back to the legitimate, I would have to take you with me,” he added.
“Never, Daddy!” cried the younger girl. “I am going to remain with the ‘movies’! I would be lost without them.”
“Assuredly, they have been a great blessing to us,” observed Ruth, quietly. “I do not know what we would have done without them, when you were stricken the second time,” and she looked fondly at her father. She thought of the dark days, not so far back, when troubles seemed multiplying, when there was no money, and when debts pressed. Now all seemed sunshine.
“Yes, it would be a poor return to the movies, to desert them after all they did for us,” agreed Mr. DeVere. “That is, as long as they care for us - those audiences who sit in the dark and watch us play our little parts on the lighted canvas.
“I little dreamed when I first took up the profession immortalized by Shakespeare, that I would be playing to persons whom I could not see. But it is certainly a wonderful advance.”
Down the bay, out through the Narrows and so on out to sea passed the Tarsus, carrying the moving picture players. The day was cold, and a storm threatened, but soon the frigid winter of the North would be left behind. This was a comforting thought to all, though Alice declared that she liked cold weather best.
Mr. Towne came up on deck, again faultlessly attired. His unexpected bath had not harmed him, in spite of the fact that it was cold, for he had at once taken warm drinks, and been put to bed, for a time, in hot blankets.
He could talk of nothing, however, save the fact that he was to be shown in the wet clothing he so despised.
“It is a shame!” he declared. “If I could find that film I would destroy it myself.”
“It is safely put away,” laughed Russ.
The day passed, and evening came. On through the darkness forged the Tarsus, while about her were the flashing beams from lighthouses, or the bobbing signal lamps from other ships.
Ruth and Alice were in their stateroom, talking together before retiring. Alice had that day’s paper and was idly glancing over it. She yawned sleepily, when an item suddenly caught her eye.
“Oh, dear!” she exclaimed. “That must be dreadful!”
“What is it?” asked Ruth, who was letting down her long hair.
“Why here’s an item from some place in Florida. It says that two girls went out in a motor boat, to gather specimens of rare swamp flowers, and have not been heard of since. It is feared they may have been upset and drowned, or that alligators attacked them. Oh, how dreadful!”
“Don’t let Mr. Sneed hear about that,” cautioned Ruth. “Where in Florida was it?”
“The item is dated from Winterhaven, but it says that the girls started from some place near Lake Kissimmee.”
“Oh!” cried Ruth, pausing with the comb half way through a thick strand of hair, “suppose it should be those two girls we met?”
“I don’t imagine it could be,” reasoned Alice. “They did not look like girls who would be bold enough to go off after swamp blooms. But think of the poor girls, whoever they are, out all alone at night, with maybe alligators around their boat! Oh, I hope we don’t have to go too far into the wilds.”
“We may,” remarked Ruth, uneasily, as she reached for the paper to read for herself the disquieting item.


public class Proxy extends Object implements Serializable
Proxy
provides static methods for creating dynamic proxy
classes and instances, and it is also the superclass of all
dynamic proxy classes created by those methods.
To create a proxy for some interface Foo
:
InvocationHandler handler = new MyInvocationHandler(...); Class<?> proxyClass = Proxy.getProxyClass(Foo.class.getClassLoader(), Foo.class); Foo f = (Foo) proxyClass.getConstructor(InvocationHandler.class). newInstance(handler);or more simply:
Foo f = (Foo) Proxy.newProxyInstance(Foo.class.getClassLoader(), new Class<?>[] { Foo.class }, handler);
A dynamic proxy class (simply referred to as a proxy
class below) is a class that implements a list of interfaces
specified at runtime when the class is created, with behavior as
described below.

A proxy instance is an instance of a proxy class.
Each proxy instance has an associated invocation handler
object, which implements the interface InvocationHandler
.
A method invocation on a proxy instance through one of its proxy
interfaces will be dispatched to the invoke
method of the instance's invocation handler, passing the proxy
instance, a java.lang.reflect.Method
object identifying
the method that was invoked, and an array of type Object
containing the arguments. The invocation handler processes the
encoded method invocation as appropriate and the result that it
returns will be returned as the result of the method invocation on
the proxy instance.
A proxy class has the following properties:
"$Proxy"
should be, however, reserved for proxy classes.
java.lang.reflect.Proxy
.
getInterfaces
on its
Class
object will return an array containing the same
list of interfaces (in the order specified at its creation), invoking
getMethods
on its Class
object will return
an array of Method
objects that include all of the
methods in those interfaces, and invoking getMethod
will
find methods in the proxy interfaces as would be expected.
Proxy.isProxyClass
method will
return true if it is passed a proxy class-- a class returned by
Proxy.getProxyClass
or the class of an object returned by
Proxy.newProxyInstance
-- and false otherwise.
java.security.ProtectionDomain
of a proxy class
is the same as that of system classes loaded by the bootstrap class
loader, such as java.lang.Object
, because the code for a
proxy class is generated by trusted system code. This protection
domain will typically be granted
java.security.AllPermission
.
InvocationHandler
, to set
the invocation handler for a proxy instance. Rather than having to use
the reflection API to access the public constructor, a proxy instance
can be also be created by calling the Proxy.newProxyInstance
method, which combines the actions of calling
Proxy.getProxyClass
with invoking the
constructor with an invocation handler.
A proxy instance has the following properties:
proxy
and one of the
interfaces implemented by its proxy class Foo
, the
following expression will return true:
proxy instanceof Foo
and the following cast operation will succeed (rather than throwing
a ClassCastException
):
(Foo) proxy
Proxy.getInvocationHandler
method
will return the invocation handler associated with the proxy instance
passed as its argument.
invoke
method as described in the
documentation for that method.
hashCode
,
equals
, or toString
methods declared in
java.lang.Object
on a proxy instance will be encoded and
dispatched to the invocation handler's invoke
method in
the same manner as interface method invocations are encoded and
dispatched, as described above. The declaring class of the
Method
object passed to invoke
will be
java.lang.Object
. Other public methods of a proxy
instance inherited from java.lang.Object
are not
overridden by a proxy class, so invocations of those methods behave
like they do for instances of java.lang.Object
.
When two or more interfaces of a proxy class contain a method with
the same name and parameter signature, the order of the proxy class's
interfaces becomes significant. When such a duplicate method
is invoked on a proxy instance, the Method
object passed
to the invocation handler will not necessarily be the one whose
declaring class is assignable from the reference type of the interface
that the proxy's method was invoked through. This limitation exists
because the corresponding method implementation in the generated proxy
class cannot determine which interface it was invoked through.
Therefore, when a duplicate method is invoked on a proxy instance,
the Method
object for the method in the foremost interface
that contains the method (either directly or inherited through a
superinterface) in the proxy class's list of interfaces is passed to
the invocation handler's invoke
method, regardless of the
reference type through which the method invocation occurred.
If a proxy interface contains a method with the same name and
parameter signature as the hashCode
, equals
,
or toString
methods of java.lang.Object
,
when such a method is invoked on a proxy instance, the
Method
object passed to the invocation handler will have
java.lang.Object
as its declaring class. In other words,
the public, non-final methods of java.lang.Object
logically precede all of the proxy interfaces for the determination of
which Method
object to pass to the invocation handler.
Note also that when a duplicate method is dispatched to an
invocation handler, the invoke
method may only throw
checked exception types that are assignable to one of the exception
types in the throws
clause of the method in all of
the proxy interfaces that it can be invoked through. If the
invoke
method throws a checked exception that is not
assignable to any of the exception types declared by the method in one
of the proxy interfaces that it can be invoked through, then an
unchecked UndeclaredThrowableException
will be thrown by
the invocation on the proxy instance. This restriction means that not
all of the exception types returned by invoking
getExceptionTypes
on the Method
object
passed to the invoke
method can necessarily be thrown
successfully by the invoke
method.

java.lang.Class
object for a proxy class
given a class loader and an array of interfaces. The proxy class
will be defined by the specified class loader and will implement
all of the supplied interfaces. If any of the given interfaces
is non-public, the proxy class will be non-public. If a proxy class
for the same permutation of interfaces has already been defined by the
class loader, then the existing proxy class will be returned; otherwise,
a proxy class for those interfaces will be generated dynamically
and defined by the class loader.
There are several restrictions on the parameters that may be

IllegalArgumentException
. If the interfaces
array argument or any of its elements are null
, a
NullPointerException
will be thrown.
Note that the order of the specified proxy interfaces is significant: two requests for a proxy class with the same combination of interfaces but in a different order will result in two distinct proxy classes.

Class NativeFileDialog
- java.lang.Object
-
- org.lwjgl.util.nfd.NativeFileDialog
-
public class NativeFileDialog extends java.lang.Object
Bindings to Native File Dialog, a tiny, neat C library that portably invokes native file open and save dialogs. Write dialog code once and have it pop up native dialogs on all supported platforms.Usage
File Filter Syntax
There is a form of file filtering in every file dialog, but no consistent means of supporting it. NFD provides support for filtering files by groups of extensions, providing its own descriptions (where applicable) for the extensions.
A wildcard filter is always added to every dialog.
Separators:
- ; Begin a new filter.
- , Add a separate type to the filter.
Examples:
- txt The default filter is for text files. There is a wildcard option in a dropdown.
- png,jpg;psd The default filter is for png and jpg files. A second filter is available for psd files. There is a wildcard option in a dropdown.
NULL
Wildcard only.
Known Limitations
- No support for Windows XP's legacy dialogs such as GetOpenFileName.
- No support for file filter names -- ex: "Image Files" (*.png, *.jpg). Nameless filters are supported, though.
- No support for selecting folders instead of files.
- On Linux, GTK+ cannot be uninitialized to save memory. Launching a file dialog costs memory.

1Password Integration Troubleshooting
If you've followed the instructions on the 1Password Feature page to enable the 1Password integration and your bookmarks are not appearing in Alfred, take a look at the troubleshooting steps below.
I'm not seeing any 1Password bookmarks in Alfred
If you type "1p" into Alfred and no bookmarks are appearing, check that the following have been enabled:
- In 1Password's own preferences, under Advanced, the "Enable integration with 3rd party apps" needs to be checked
- In Alfred's Features > 1Password preferences, the "Enable 1Password Bookmarks" box also needs to be checked
- If you've changed your keyword from "1p", be sure to use the correct keyword
- If you've checked the "Show in default results without keyword", you should simply type the name of the website in Alfred without the prefix.
Some of my 1Password entries aren't showing up in Alfred
First, launch Alfred's preferences to Features > 1Password to check whether the URL is included in the list of bookmarks Alfred has access to.
Only users of 1Password 6.5+ and Alfred 3.2+ will be able to open items from Team and Family vaults, as well as secure notes and non-website entries. On older versions, 1Password only shares 1Click Bookmarks from your primary vault, excluding all other file types.
If Alfred is listing some of your password, but new ones are missing, it may be that Alfred is looking at the wrong 1Password file.
Click on the "Advanced" button in the bottom right of Alfred's 1Password preferences, and "Discover automatically" should be checked. You can uncheck and re-check the box, which will cause Alfred to look once again for the relevant third-party integration file.
If the box is not checked, you've manually set the location of the third-party integration file. This will only be necessary if you store the file in an unusual location.
When I choose a 1Password result in Alfred, I get an error message.
If you're seeing the message "There is no application set to open the URL...", macOS doesn't know it should launch the URL in a web browser. This is due to your URL missing the http:// or https:// part of the URL.
To correct this, launch 1Password to the entry. Click in the "website" field and add http:// or https:// as appropriate at the beginning of the URL. Save your login and it should launch correctly next time you select it in Alfred.
