That’s the situation. A web application with 4 heavy queries. Yes I know you can use a cache or things like that but imagine you must perform the four queries yes or yes. As I say before the four database queries are heavy ones. 2 seconds per one. Do it sequentially, that’s means our script will use at least 8 seconds (without adding the extra PHP time). Eight seconds are a huge time in a page load.
So here I will show up a technique to speed up our website using asynchronous calls.
One possible solution is fork each query into a separate thread but, does PHP support threads? The short is answer No. OK that’s not 100% true. We can use PCNTL functions but it’s a bit tricky for me to use them. I prefer to use this another solution to create fork and perform asynchronous operations.
The basic idea is isolate each query into a separate script.
// fork.php
$dbh = new PDO('pgsql:dbname=pg1;host=localhost', 'nov', 'nov');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$t = filter_input(INPUT_GET, 't', FILTER_SANITIZE_STRING);
switch ($t) {
case 0;
case 1;
case 2;
$sql = "select * from test.tbl1";
break;
}
$stmt = $dbh->prepare($sql);
$stmt->execute();
$data = $stmt->fetchAll();
echo json_encode($data);
And now we are going to use the curl’s multi functions to execute the database queries at the same time:
// index.php
class Fork
{
private $_handles = array();
private $_mh = array();
function __construct()
{
$this->_mh = curl_multi_init();
}
function add($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_multi_add_handle($this->_mh, $ch);
$this->_handles[] = $ch;
return $this;
}
function run()
{
$running=null;
do {
curl_multi_exec($this->_mh, $running);
usleep (250000);
} while ($running > 0);
for($i=0; $i < count($this->_handles); $i++) {
$out = curl_multi_getcontent($this->_handles[$i]);
$data[$i] = json_decode($out);
curl_multi_remove_handle($this->_mh, $this->_handles[$i]);
}
curl_multi_close($this->_mh);
return $data;
}
}
$fork = new Fork;
$output = $fork->add("http://localhost/fork.php?t=0")
->add("http://localhost/fork.php?t=1")
->add("http://localhost/fork.php?t=2")
->run();
echo "<pre>";
print_r($output);
echo "</pre>";
And that’s all. Four queries will be executed at the same time and our scrip will use 2 seconds (the slowest query) instead of 8 seconds. But there’s a little inconvenient within this solution. We need to open 4 connections instead of one because of the lack of connection pooling in PHP. Another problem with this technique appears if we need to debug our script. The debugger won’t debug our “forks” at the same time (we will need to debug then separately). Because of that we need to balance the usage of this technique or not, but it’s another weapon we have to improve our scripts.


Varkrona is a comprehensive online resource tool dedicated to COVID-19 screening, offering psychological support and engagement to those in need and tracking the spread of the disease. By answering a list of questions including symptoms, risk factors and exposure, screened patients will then be given a directive about when to seek testing or emergency care.The mental toll COVID-19 is taking on the public and front-liners is addressed, and the app will provide access to support and engagement for those in need, with specific focus in depression, anxiety and stress. The app consists of a self-directed questionnaire which can help determine if the user should speak with a mental health professional. Varkrona, as an app will then match the user to a therapist for their specific needs.Users can also alleviate their doubts and worries by accessing curated content centered on stress management, staying active and eating and sleeping well, including webinars, blog posts and links about staying healthy and means to help users deal with the pandemic. The app also tracks the current spread of COVID-19 in Malaysia by releasing a live dashboard from the MOH, WHO and CDC to track the virus in real time and includes information about cases by region and country, as well as the deaths. The information is displayed in a map and in corresponding charts.


module ActiveRecord::Transactions::ClassMethods
Active Record Transactions¶ ↑
Transactions are protective blocks where SQL statements are only permanent if they can all succeed as one atomic action. The classic example is a transfer between two accounts where you can only have a deposit if the withdrawal succeeded and vice versa. Transactions enforce the integrity of the database and guard the data against program errors or database break-downs. So basically you should use transaction blocks whenever you have a number of statements that must be executed together or not at all.
For example:
ActiveRecord::Base.transaction do david.withdrawal(100) mary.deposit(100) end
This example will only take money from David and give it to Mary if neither
withdrawal
nor deposit
raise an exception.
Exceptions will force a ROLLBACK that returns the database to the state
before the transaction began. Be aware, though, that the objects will
not have their instance data returned to their pre-transactional
state.
Different Active Record classes in a single transaction¶ ↑
Though the transaction class method is called on some Active Record class, the objects within the transaction block need not all be instances of that class. This is because transactions are per-database connection, not per-model.
In this example a balance
record is transactionally saved even
though transaction
is called on the Account
class:
Account.transaction do balance.save! account.save! end
The transaction
method is also available as a model instance
method. For example, you can also do this:
balance.transaction do balance.save! account.save! end
Transactions are not distributed across database connections¶ ↑
A transaction acts on a single database connection. If you have multiple class-specific databases, the transaction will not protect interaction among them.  So you can use validations to check
for values that the transaction depends on or you can raise exceptions in
the callbacks to rollback, including after_*
callbacks.
As a consequence changes to the database are not seen outside your
connection until the operation is complete. For example, if you try to
update the index of a search engine in after_save
the indexer
won't see the updated record. The after_commit
callback is
the only one that is triggered once the update is committed. See below.
Exception handling and rolling back¶ ↑
Also have in mind that exceptions thrown within a transaction block will be propagated (after triggering the ROLLBACK), so you should be ready to catch those in your application code.
One exception is the ActiveRecord::Rollback
exception, which
will trigger a ROLLBACK when raised, but not be re-raised by the
transaction block.
Warning: one should not catch
ActiveRecord::StatementInvalid
exceptions inside a transaction
block. ActiveRecord::StatementInvalid
exceptions indicate that
an error occurred at the database level, for example when a unique
constraint is violated. On some database systems, such as PostgreSQL,
database errors inside a transaction cause the entire transaction to become
unusable until it's restarted from the beginning. Here is an example
which demonstrates the problem:
# Suppose that we have a Number model with a unique column called 'i'. Number.transaction do Number.create(i: 0) begin # This will raise a unique constraint error... Number.create(i: 0) rescue ActiveRecord::StatementInvalid # ...which we ignore. end # On PostgreSQL, the transaction is now unusable. The following # statement will cause a PostgreSQL error, even though the unique # constraint is no longer violated: Number.create(i: 1) # => "PGError: ERROR: current transaction is aborted, commands # ignored until end of transaction block" end
One should restart the entire transaction if an
ActiveRecord::StatementInvalid
occurred.
Nested transactions¶ ↑
transaction
calls can be nested. By default, this makes all
database statements in the nested transaction block become part of the
parent transaction. For example, the following behavior may be surprising:
User.transaction do User.create(username: 'Kotori') User.transaction do User.create(username: 'Nemu') raise ActiveRecord::Rollback end end
creates both “Kotori” and “Nemu”. Reason is the
ActiveRecord::Rollback
exception in the nested block does not
issue a ROLLBACK. Since these exceptions are captured in transaction
blocks, the parent block does not see it and the real transaction is
committed.
In order to get a ROLLBACK for the nested transaction you may ask for a
real sub-transaction by passing requires_new: true
. If
anything goes wrong, the database rolls back to the beginning of the
sub-transaction without rolling back the parent transaction. If we add it
to the previous example:
User.transaction do User.create(username: 'Kotori') User.transaction(requires_new: true) do User.create(username: 'Nemu') raise ActiveRecord::Rollback end end
only “Kotori” is created. This works on MySQL and PostgreSQL. SQLite3 version >= '3.6.8' also supports it.
Most databases don't support true nested transactions. At the time of writing, the only database that we're aware of that supports true nested transactions, is MS-SQL. Because of this, Active Record emulates nested transactions by using savepoints on MySQL and PostgreSQL. See dev.mysql.com/doc/refman/5.6/en/savepoint.html for more information about savepoints.
Callbacks¶ ↑
There are two types of callbacks associated with committing and rolling
back transactions: after_commit
and
after_rollback
.
after_commit
callbacks are called on every record saved or
destroyed within a transaction immediately after the transaction is
committed. after_rollback
callbacks are called on every record
saved or destroyed within a transaction immediately after the transaction
or savepoint is rolled back.
These callbacks are useful for interacting with other systems since you
will be guaranteed that the callback is only executed when the database is
in a permanent state. For example, after_commit
is a good spot
to put in a hook to clearing a cache since clearing it from within a
transaction could trigger the cache to be regenerated before the database
is updated.
Caveats¶ ↑
If you're on MySQL, then do not use DDL operations in nested
transactions blocks that are emulated with savepoints. That is, do not
execute statements like 'CREATE TABLE' inside such blocks. This is
because MySQL automatically releases all savepoints upon executing a DDL
operation. When transaction
is finished and tries to release
the savepoint it created earlier, a database error will occur because the
savepoint has already been automatically released. The following example
demonstrates the problem:
Model.connection.transaction do # BEGIN Model.connection.transaction(requires_new: true) do # CREATE SAVEPOINT active_record_1 Model.connection.create_table(...) # active_record_1 now automatically released end # RELEASE savepoint active_record_1 # ^^^^ BOOM! database error! end
Note that “TRUNCATE” is also a MySQL DDL statement!
Public Instance Methods
This callback is called after a record has been created, updated, or destroyed.
You can specify that the callback should only be fired by a certain action
with the :on
option:
after_commit :do_foo, on: :create after_commit :do_bar, on: :update after_commit :do_baz, on: :destroy after_commit :do_foo_bar, on: [:create, :update] after_commit :do_bar_baz, on: [:update, :destroy]
Note that transactional fixtures do not play well with this feature. Please
use the test_after_commit
gem to have these hooks fired in
tests.
# File lib/active_record/transactions.rb, line 237 def after_commit(*args, &block) set_options_for_callbacks!(args) set_callback(:commit, :after, *args, &block) unless ActiveRecord::Base.raise_in_transactional_callbacks ActiveSupport::Deprecation.warn(CALLBACK_WARN_MESSAGE) end end
This callback is called after a create, update, or destroy are rolled back.
Please check the documentation of after_commit
for options.
# File lib/active_record/transactions.rb, line 248 def after_rollback(*args, &block) set_options_for_callbacks!(args) set_callback(:rollback, :after, *args, &block) unless ActiveRecord::Base.raise_in_transactional_callbacks ActiveSupport::Deprecation.warn(CALLBACK_WARN_MESSAGE) end end
See ActiveRecord::Transactions::ClassMethods for detailed documentation.

What is the relationship between mindfulness and self awareness?
In the book Search Inside Yourself, Jon Kabat-Zinn describes mindfulness as "paying attention in a particular way: on purpose, in the present moment, and non-judgmentally. In the same book, Daniel Goleman describes self-awareness "as a neutral mode that maintains self-reflectiveness even in the midst of turbulent emotions". Both mindfulness and self-awareness require a focused mind and an 'in the moment approach' to the task or the emotion at hand. Mindfulness can be achieved through meditation which can be taught and practised over time so we safely assume that mindfulness can also be taught and practiced over time also.
Try at least one of the self awareness practices from the chapter (Body Scan, Journaling). What was your experience of it? How did you feel?
I tried body scanning and found it very similiar to meditation. I actually found it easier to practice than meditation as there was a physical outline/structure to focus on. Each meditation can be different as you can start on a different point on the body and vary the journey choosing which direction you go in. I found I could focus my attention much easier and for a longer period of time in comparison to the other meditation techniques I have practiced before.

Welcome to a Software Engineering project by Danielle, Collin, and Matt. Our project is an implemenation of the Shamir Secret Sharing Scheme using a web interface.
What is the Shamir Scheme you ask? Good question, thanks for asking. Shamir's scheme is an encryption algorithm which segments a piece of data,
in our case a string of text characters into coordinates on a polynomial function. The segments are encryped and can be distributed among individuals who then need to each enter their respective parts of the secret to reconstruct it.
With the Shamir scheme, many quantities of parts can be generated from the secret, and a minimum number of parts can be specified as needed in order to rebuild the secret. The secret is not
Stored within the program or database once it is encrypted, and must be mathematically uncovered by Lagrange interpolation in order to be revealed again.
We hope this demonstration is informative, thanks for visiting!

Batam pier collapse: 26 Singaporeans from MENDAKI injured during company retreat
by Aqil Haziq MahmudBATAM: Twenty-six Singaporeans, all employees of self-help group Yayasan MENDAKI, were injured after a wooden pier collapsed at Montigo Resorts on the Indonesian island of Batam, the organisation confirmed on Friday (Nov 8).
The staff members were on a company retreat to discuss work plans for the upcoming year, MENDAKI said.
On Thursday, tourists were taking photos on the 70m-long pier at the resort when the middle section of the pier collapsed. More than 30 people fell into the ocean, Riau police official Erlangga had said.
The injured included the 26 MENDAKI employees, all Singaporean. Earlier reports said that 18 Singaporeans were injured.
"Twenty-four employees had light injuries and were discharged as outpatients. Two employees will seek further medical care in Singapore," MENDAKI said, adding that the next-of-kin of those injured had been contacted.
A spokesperson from Singapore's Ministry of Foreign Affairs said earlier on Friday: "We are aware of the incident. Officers from the Consulate-General in Batam are at Bhayangkara Hospital to render consular assistance."
INJURED SINGAPOREANS ON THEIR WAY BACK
At least four Singaporeans who were injured were on a ferry back to Singapore on Friday.
Two of the injured were seen by CNA on stretchers at the departure area of the Nongsapura ferry terminal in Batam. Another two were in wheelchairs. There were also two ambulances outside the terminal.
Ferry terminal staff confirmed that the two on stretchers were Singaporeans injured in the incident, and that they were due to take the 9am (10am Singapore time) ferry back to Singapore’s Tanah Merah Ferry Terminal.
“They were accompanied by doctors,” the staff member, who declined to be named, told CNA.
Over the next half an hour, dozens of tourists disembarked from three tour buses - one with a Montigo Resorts logo - and headed straight to the Batam Fast ferry ticket counter.
Among them were a man and a woman in wheelchairs. A representative from Singapore’s Ministry of Foreign Affairs greeted them as they disembarked.
“I think we are all okay,” one woman in the group told CNA. “It is a shock, of course. When a bridge falls, you will be shocked. Otherwise, we are all okay.”
Two other tourists declined to comment. A man who was on his computer seemingly handling administrative tasks said: “We were advised not to speak to the media.”
Editor's Note: Initial reports on the incident referred to the collapsed structure as a bridge. This story has been updated to correctly describe it as a pier.

Everyday support desks all over the world support millions of users. Each of these users presents their own unique problem and wants to know how long it will take for this problem to be solved. This presents a challenge to the help desk staff who cannot provide accurate estimates for every issue. We propose the use of machine learning techniques in order to provide a prediction for how long an issue will take to complete at the time of creation. Implementing these predictions will allow for helpdesk staff to not only provide users with a more accurate estimate of when their issue will be resolved but could also help identify any possible bottlenecks that could be avoided or made more efficient to provide better service. For example maybe we might notice a support group which takes a long time to process tickets because they are receiving too many issues which might suggest they are short staffed.
Our features are attributes of the ticket, such as date and time submitted, its categorization, etc. We trained our data using a variety of different machine learning algorithms, focusing on algorithms which provided rules. We then compared the accuracy of these algorithms using 10-fold cross validation on each. We found the algorithms that yielded the highest accuracy to be the J48 decision tree and IBk Nearest Neighbors Algorithms and fine tuned their parameters to get the highest accuracy. Figure 1 shows the learning curve for the J48 algorithm on our training instances. We then used these tuned algorithms and ran them against a held out test set to provide the results below
Figure 1:The learning curve produced by the J48 Decision Tree Algoritmh on our data
Using the J48 learning algorithm the best accuracy we achieved was 66.5%. This accuracy is not as high as we hoped to achieved and we believe there are several reasons for that. First of ou 8690 instances about 63% were in the category of "12 hours or Less" While the rest of the instances were split among 10 categories, along with this we were missing key attributes including who worked on the issue and what support tools were used. Despite this we were still able to garner some useful information from our decision tree. Looking at the top decision attributes within the tree we found the most important attributes are whether the ticket was assigned to the main support center or elsewhere, and if the ticket was submitted during a weekday or the weekend. We also found that issues regarding "Our Northwestern" tend to take longer to resolve which is something worth investigating to see if the efficiency of such issues can be improved.
Overall, there's still a lot more work to be done before this could be used by support staff to provide accurate estimates but we believe that using more data and a few additional attributes, particularly attributes such as who submitted and worked on the issue, and features gathered from the description and title of the issue would greatly improve accuracy.

About 2 hours later, I was on a telephone conference call and started feeling jittery, then suddenly my jaw just started opening and closing and I couldn't control it, I was stuttering into my conference call. I had to slam down the phone. Next thing I remember, I woke up to see a complete stranger staring into my face asking if I was OK. that stranger, about a minute later, turned out to be my best friend at work. Complete amnesia, temporarily. There were paramedics there and I was told I had a grand-mal seizure, right there in my cubicle. I remember nothing of it. I went to the hospital and gradually (within an hour) remembered what medicines I had taken to do this to me.
I will NEVER take a tri-cyclic again, and ultram maybe in very small doses.

Searching a website from a computer by the server a communication starts by HTTP to look up the website.
Hypertext Transfer Protocol “HTTP” is the language used to communicate between web browsers and servers.
If you are interpreted conversation between the computer and the web server on the internet, then asking for getting requests.
Hypertext Markup Language “HTML” to users and tell the web browsers how does the page look.
For example, the text of the page includes directly in the HTML but the other part such as images/videos are separate files with unique Uniform Resource Locator (URLs) that need to be requested. The browser sends separate HTTP requests to each of these and displays them as they arrive.
The internet is completely open, connections are shared, information is sent in plain text. This makes it possible to get hack from hacker snoop on any personal information that sends over the internet. But the safe website prevents snooping and tampering by asking the web browser to communicate on a secure channel which is called secure sockets layer and transport layer security. SSL and TLS are a layer of security around the communications to protect them from snooping and tampering.
HTTP and DNS manage the sending and receiving of the web files such as HTML, media files, or anything on the web.

Working with Media APIs
Working with Media APIs
Multimedia can bring your app to life. In this module, you'll explore the ways you can add images, sounds, and videos to your apps. You'll also learn how to capture images from the camera or retrieve them from the user's gallery.
Sections in this chapter
In this chapter, you'll learn how to play and record sounds. As with images, you'll see you can play both local and remote sound files, and have programmatic control over that playback.
Next, you'll look at how you can embed videos within your apps. You'll see how to play both local files and how to stream remote videos.
If you've been following along in these tutorials, you'll already know the basics of adding images. In this section, you'll dig a bit deeper into the ways you can add local and remote images to your apps as either background images or ImageViews.
We'll close out this chapter by exploring the camera and photo gallery APIs. You'll see how to capture an image from the camera, use it in an app, and save it to the gallery or filesystem. You'll also explore the closely related gallery APIs, which let your users grab images from their photo albums for use within your app. So let's get started: Audio APIs >

This example shows how to configure Telerik TreeView for ASP.NET MVC to load its nodes through Ajax requests. The request is performed only once. After that the content is rendered on the page and treeview shows/hides it without performing additional requests.
You can bind the treeview to an ActionMethod that will get requested through AJAX, or to an ASMX / WCF web service, using the DataBinding method.
<%= Html.Telerik().TreeView() .Name("TreeView") .DataBinding(dataBinding => dataBinding .Ajax().Select("_AjaxLoading", "TreeView") ) %>
You can load the whole treeview from scratch, or load the initially visible nodes using the BindTo method, like the root node in this example.

supports the training and evaluation of BigDL models, Keras-like models and PyTorch models. It wraps a model, and provide a uniform training, evaluation, or prediction operation on both localhost and distributed spark environment.
Creating an Estimator
In summary, you need to supply three parameters to create an Estimator: 1)a model, 2) optimMethod (s), 3) model directory, as shown below:
Scala:
val estimator = Estimator[T: ClassTag](
model: Module[T],
optimMethods: Map[String, OptimMethod[T]] = Map(),
modelDir: Option[String] = None)
T
: the numeric type(Float/Double).
model
: the model will be optimized.
optimMethods
: the methods to optimize the model. Submodule names and optimMethod pairs.
modelDir
(Optional): model checkpoint directory, and related summary directory.
val estimator = Estimator[T: ClassTag](
model: Module[T],
optimMethod: OptimMethod[T],
modelDir: Option[String] = None)
T
: the numeric type(Float/Double).
model
: the model will be optimized.
optimMethod
: the method to optimize the model.
modelDir
(Optional): model checkpoint directory, and related summary directory.
Python:
estimator = Estimator(model, optim_methods, model_dir)
model
: the model will be optimized.
optim_methods
: the methods to optimize the model. Both single optimMethod and Dict(submodule
name, optimMethod) are supported.
model_dir
(Optional): model checkpoint directory, and related summary directory.
Training
Train the model with provided trainSet and criterion. The training will end when the endTrigger is triggered. During the training, if the checkPointTrigger is defined and triggered, the model will be saved to modelDir. And if validationSet and validationMethod are defined, the model will be evaluated at the checkpoint.
Scala:
estimator.train(trainSet: FeatureSet[MiniBatch[T]],
criterion: Criterion[T],
endTrigger: Option[Trigger] = None,
checkPointTrigger: Option[Trigger] = None,
validationSet: FeatureSet[MiniBatch[T]] = null,
validationMethod: Array[ValidationMethod[T]] = null)
trainSet
: training dataset in type of FeatureSet[MiniBatch].
criterion
: loss function.
endTrigger
: when to finish the training.
checkPointTrigger
: how often to save a checkpoint and evaluate the model.
validationSet
: validation dataset in type of FeatureSet[MiniBatch].
validationMethod
: a set of validationMethod.
Python:
Train Samples
estimator.train(train_set, criterion, end_trigger, checkpoint_trigger,
validation_set, validation_method, batch_size)
train_set
: training dataset in type of FeatureSet[Sample[T]].
criterion
: loss function.
end_trigger
: when to finish the training.
checkpoint_trigger
: how often to save a checkpoint and evaluate the model.
validation_set
: validation dataset in type of FeatureSet[Sample[T]].
validation_method
: a set of validationMethod.
batch_size
: mini batch size.
Train ImageFeatures
estimator.train_imagefeature(self, train_set, criterion, end_trigger, checkpoint_trigger,
validation_set, validation_method, batch_size)
train_set
: training dataset in type of FeatureSet[ImageFeature].
criterion
: loss function.
end_trigger
: when to finish the training.
checkpoint_trigger
: how often to save a checkpoint and evaluate the model.
validation_set
: validation dataset in type of FeatureSet[ImageFeature].
validation_method
: a set of validationMethod.
batch_size
: mini batch size.
Evaluation
Evaluate the model on the validationSet with the validationMethods.
Scala:
estimator.evaluate(validationSet: FeatureSet[MiniBatch[T]],
validationMethod: Array[ValidationMethod[T]])
validationSet
: validation dataset in type of FeatureSet.
validationMethod
: a set of validationMethod.
Python:
Evaluate Samples
estimator.evaluate(validation_set, validation_method, batch_size)
validation_set
: validation dataset in type of FeatureSet[Sample[T]].
validation_method
: a set of validationMethod.
batch_size
: mini batch size.

Hollow Man
Don't you hate it when a movie has a great premise and looks like it could be something fresh and exciting it turns out to be just another [insert genre here] flick?
That's what happens with "Hollow Man" - it's a story that involves the discovery of a chemical that turns living things invisible. This would seemingly be a good method to explore human psychology, especially of voyeurism and insecurity. It might also be a study of the basic human fear of that which we can't see scares us. But what do we actually get with this movie - a terribly generic sci-fi/horror thriller about a man who who's just a big baby and has to have his way all the time.
Kevin Bacon stars as Dr. Sebastian Caine - a scientist working on the invisibility project for the pentagon in a secret underground lab. He is surrounded of course by his ex-girlfriend Linda McKay (Elizabeth Shue) who has dumped him for fellow scientist Matt Kensington (Josh Brolin). Caine never gets his way and when he does turn himself invisible he does explore, uh, his "inner perversions." But for some reason he goes nuts and starts killing everybody.
What makes the film so flawed is not just the fact Caine snaps for no justifiable reason, it's that there's no backstory to the any of the characters so no one in the film has any real motivation. This is compounded by a screenplay which does nothing to further the story for the majority of the movie (it's mostly the scientists sitting around in the lab). The topper is the ending which is so over-the-top with one classic slasher horror cliche after another it's laughable. It's a movie about an invisible man and what do we end up with - fistfights and shootouts and explosions and elevators crashing?!?! If we wanted to see that we would have rented a "Die Hard" video.
I think Paul Verhoeven just likes to use special effects at the expense of a workable screenplay.

French zoo finds runaway red panda
LYON: A zoo in central France said it found a runaway red panda on Saturday (Nov 23), a week after it escaped by scaling branches broken by snowfall.
The zoological park in Saint-Martin-la-Plaine said a man discovered the endangered furry mammal in his garden.
"We were called this morning around 8.15am by a resident. He saw the red panda on a shrub in his garden," said park vet Dr Jean-Christophe Gerard in a statement.
A team headed immediately to the site and recovered the red panda.
"The little panda appears to be in good health and has not suffered from his stay outside the park, even if he is a bit thinner," Gerard said.
The three-year-old male escaped from the park last Thursday, taking advantage of heavy snowfall that brought down trees.
His female partner did not follow him out of the zoo.
On Wednesday, a driver spotted the animal some 10km from the zoo but the police and zoo staff were unable to locate it.
The shy creatures spend most of their time in trees and are not considered dangerous.
Vets will be monitor the panda over the next few days to ensure his well-being.

When a character is stuck in a high place of some sort and has nowhere to go but down, he uses anything wire-like to fly down. Gripping onto a wire hanger is a common variation to the trope; however, this is a decidedly horrible idea, as the MythBusters have busted this one's plausibility.
Real ziplines require specific, strong materials for both the line and the thing being held, so that neither one breaks, and so that the friction doesn't stop the slider halfway down the rope.
Not to be confused with Fast-Roping. A supertrope of Bedsheet Ladder.
Examples:
- In the commercials for Push Pop, the cartoon character uses the Push Pop itself to slide across a rope between buildings.
- In a MasterCard commercial, MacGyver escapes from a room with a bomb in it using a tube sock. Tube sock: $4. Refuge in Audacity: Priceless
- This Levi's jeans ad has the hero use his jeans to rescue a babe from a high-rise fire.
- Pokémon Adventures:
- Ruby uses his Pokeblock case as a zipline on the thread his Marshtomp is holding up to escape the flames Courtney is trying to kill him with.
- Earlier, Janine uses her Ariadosnote as a zipline, with it retracting silk from one end and shooting it out from another.
- In an Anpanman theatrical short, Uncle Negi, having left his basket full of green onions (which also contains his Naganegiman costume and sword) at the bottom of Princess Doremi's castle grounds, uses his scarf as a zipline...and promptly crashes face first into a tree at the bottom.
- Chicken Run did it with coat hangers.
- Disney likes this one a lot in their Animated Fare or otherwise:
- In Mulan, the heroine uses a string of lanterns to zip down from the roof.
- In The Emperor's New Groove, Kuzco and Pacha, who are trying to beat Yzma and Kronk to the palace, cross a ravine by firing an arrow with a rope attached into a tree on the other side, tying the rope to the tree on their side, and then zipping down on it.
- In Shrek 2, Prince Charming shoots an arrow with a rope tied to it and then uses his bow to zip across the fiery moat of lava.
- And later in the film, Shrek does this with a bridge chain while Storming the Castle.
- Kung Fu Panda 2: Po uses the same lantern string variation as the page image.
- Scooby-Doo! Pirates Ahoy! has Shaggy and Scooby sliding down a mast rope with a mop handle.
- In Toy Story 3 Buzz slides on the yarn holding up kid's pictures in the nursery to escape out the window.
- In Up, Carl does a short zip-line with a garden hose and his own cane.
- In The Dark Knight, the opening bank robbery has Happy and Dopey land on the roof of the bank by firing a cable launcher from an office building across the street, then ziplining over the street on the new cable.
- Tango & Cash. While escaping prison, Stallone and Russell's characters use their belts and the prison's electric lines in this manner to get over the brick wall surrounding the prison.
- Home Alone has Kevin using a sawn-off bike handlebar to slide from his window to his treehouse.
- This same variation happens in Sleepover, but with a wire hanger.
- In Back to the Future, the Mad Scientist Doc Brown uses the wire to slide down from a clock tower, rushing to connect a loose cable in time for the lightning strike.
- Rush Hour 2 to escape an explosion.
- Captain Jack Sparrow in Pirates of the Caribbean: The Curse of the Black Pearl did this with the chain on his handcuffs. It is worth noting that it is topologically impossible to hook handcuffs secured between your hands over a wire attached at both ends and then jump off again at the bottom. Close observation reveals that Jack actually forms a short noose from the chain and throws that over the wire, which makes the feat possible - and even cooler.
- In Enchanted, Pip the Chipmunk did it on a wire with a clothes hanger.
- Chris pulls one off in Eight Legged Freaks. The Giant Spider that tries to follow falls off.
- James Bond
- Never Say Never Again. While infiltrating a terrorist hideout at the beginning of the movie, Bond climbs up a pole and slides down a telephone (?) wire onto the roof.
- Moonraker. Bond and Holly Goodhead use a chain to slide down a cable car cable in order to escape from Jaws.
- A deleted scene in The Living Daylights had Bond improvise a 'flying carpet' by throwing a carpet over some telephone wires and sliding down them to escape the police in Tangier. Stills of this scene were seen in a lot of publicity material for the film, but it was ultinately decided that this silly scene did not sit well with Timothy Dalton's Darker And Grittier Bond.
- The Social Network. Mark and friends make a zipline from the roof (tied to the chimney) to the pool. After just two jumps the chimney breaks and the zipline falls.
- Santa uses a candy cane to zip down a string of Christmas lights in the animated opening of National Lampoon's Christmas Vacation.
- The Return of the Pink Panther. The thief escapes from the museum with the diamond by firing a zip line from a crossbow to an adjacent building, then sliding down the line into an apartment in the other building.
- Who Framed Roger Rabbit. Judge Doom uses his cane to slide down a wire and attack Eddie Valiant on top of the Dip wagon.
- Batman: The Movie (1966). During the battle on the submarine, the Penguin uses his umbrella to slide down a wire and knock down Batman with a kick.
- In The Adventures of Tintin, The eponymous character is seen using the handle of a motorbike to slide down a cable during his pursuit of a falcon in Bagghar.
- Hudson Hawk. While robbing the Vatican, Eddie throws a rope (with a grappling hook on the end) from the top of a building across a street. He then slides down the rope to escape.
- Spoofed in Water (1985). A communist rebel played by Billy Connolly is attacking the local radio station by sliding down a telephone cable (even though he could have walked up to the door, as it's totally undefended). He misjudges his distance and goes crashing through the roof instead.
- Chazz Michael Michaels performs one of these with his jock strap in Blades of Glory.
- In Like Flint. While on a mission in Moscow, Flint is pursued by Soviet agents. He jumps onto the top of a tower and fires a line to the top of another building using his multi-function lighter. He then slides down the line to the top of the building and safety.
- Robin Hood (2018): At the mines, Robin jumps off an elevated walkway and hooks his bow over a conveniently placed rope; sliding down it to land in the back of John's wagon.
- Slipstream (1989). A wind-worshipping cult has tied Byron to a kite flying the eponymous slipstream. Owens clips himself to the kite's anchor rope and pulls the cord on his parachute, which opens immediately in the storm and pulls him up the rope to the kite, so he can cut Byron loose. Getting down however is the difficult part.
- Kaleidoscope: Barney breaks in to the Kaleidoscope factory by attaching a grooved wheel to the end of his cane, and then using an electric power line as a zip line to zip across the street to the Kaleidoscope roof.
- This happens in the Scott Westerfeld novel Leviathan: Deryn is up in a scouting balloon and sees Alek's "family" coming to the shipwreck looking for him in their Stormwalker. The message lizard won't get down the cable in time, so she slings a leather strap over the tether and zips down to camp. The book also goes into detail about how and why this sort of action is dangerous and shows the sort of things Deryn has to do to prevent snapping her wrists/neck.
- In False Mirrors, the heroes use their uniform belts to slide down vertical kilometer-long high-tension cables. They, however, are in Unreal-based Virtual Reality game, so it's justified. And still, Gengis's belt snaps at the last second, and he barely survives a 20-story drop with a measly couple of HP.
- "Spy Trap", an Alex Rider short story, sees the protagonist use a clothes hanger, a security drone and fishing wire to bypass an electric fence.
- Nick Velvet: In "The Theft of the Mafia Cat", Nick sneaks the eponymous cat out of the fortified mansion by placing it in a plastic bag and using fishing line to slide it down a telephone line and over the wall of the estate.
- In Chuck season 3 when he was training to be a "real" spy, Chuck had to do a zipline using a power line and his belt as the pulley, but failed. Then at the end of the ep he was forced to use a power line as a zip line with his belt as the pulley. This time he succeeded.
- Jason and the Argonauts has the Argonauts pursued by an army and come across a ravine. One produces a rope with which to climb down, but Jason has a better idea, tying the rope to a shield and asking Hercules if he's any good at the discus. Once the shield is thrown, the Argonauts cross on the improvised zipline, only waiting for the enemy to start crossing to cut the rope.
- Busted by the MythBusters in the case of using your pants to zip down a ski lift: There's too much friction, the angle of the lift isn't steep enough, and either the pants or your grip will fail first.

- In "Back from the Dead", Mac escapes from two mafia hit men using a fire hose to slide down a metal wire. First cut off with his Swiss army knife of course.
- In "Children of Light", MacGyver creates a zip line to escape from the roof of a building using a steel shaft from a large TV antenna and a large rope. He ties one end of the rope to the building and throws the other end to Pete Thornton who ties it to the bumper of his van. Pete then gets the driver to move the van forward in order to tighten the line. Meanwhile Mac bends the shaft of the TV antenna into the shape of a hook and uses his jacket to protect his hand from the friction, and proceeds to slide down the line with another person (whom he was trying to free from the building).
- In Final Fantasy X, the ship fires massive anchor cables into the building the characters need to get to, but since it's under fire, it can't stay long, so the party surfs down the cables onto the building.
- Uncharted: Drake uses several wires and his pistol to zipline down quickly.
- Monkey Island did it with a rubber chicken. With a pulley in the middle.
- Alpha Protocol features this a lot.
- Mirror's Edge features Faith doing this WITH HER HANDS. Careful observation will note that her gloved hand always is in direct contact with the wire, thereby Handwaving the damage one would normally receive from such a stunt, but it far from excuses it.
- Jack from MadWorld can do this with certain steel wires, but only because it's a steel hand with a Chainsaw in it.

 - The Simpsons:
- Parodied in "The Springfield Connection"; Herman, the one-armed weapon seller, takes a pair of bootleg designer jeans and tries to get away using them to zipline out of Bart's treehouse. However, the jeans rip partway down as Herman laments "Foiled by my own shoddy merchandise!"

Also ,the cable doesnt extend all the way to the surface, so the two end up plummeting to the ground one they reach the end of the cable.
- Two men once created a zipline with a crossbow and abseiled over the Berlin Wall.
- One Darwin Awards winner decided to use a karabiner clip to slide down the cable of a disused chairlift. Too late he discovered that he had no way to arrest his acceleration and no to disengage himself from the karabiner. He collided fatally with a pylon.

HTTP means HyperText Transfer Protocol. HTTP is the underlying protocol used by the World Wide Web and this protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands
Hypertext Transfer Protocol Secure (HTTPS) is a variant of the standard web transfer protocol (HTTP) that adds a layer of security on the data in transit through a secure socket layer (SSL) or transport layer security (TLS) protocol connection.
Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses

I wish I could tell you my donor how grateful I am for your selfless act.You gave me new life. We may be coworkers or schoolmates or just two in the same community.I'm very grateful to you.
