I am reporting this experience because of train-wreck disaster occurred. This is a report of an hospitalization following a 25I-NBOMe ingestion.
My previous experiences with hallucinogens are various; 2C-C, 2C-D, 2C-E, DOI, DOC, Methoxetamine, BromoDragonFLY, LSD, Mushrooms, DXM, Methylone, 5-meO-MIPT, 4-HO-MIPT, 4-HO-MET, ect…
However, this report consists of a friend’s first time trip. My friend is an 18 yo healthy individuals with no experiences at all with tripping. He only has a drink sometimes and he only smoke marijuana two times.
My friend was interested in tripping but unfortunately, I cannot have my hands on something relatively “safe” such as LSD, Mushrooms or DMT. I warn him that I only have research chemicals at my disposal.
Due to the large numbers of experiments of 25I-NBOMe that proliferate on the Internet and the “safe” feeling profile that outcome, I thought it was the perfect choice for a first timer. How wrong I was!!
He agrees that he will try this substance. We called him “G”. For the experience, we planned to invite some friends and especially a sober one. I called a trusted friend to come at my house for tomorrow.
The day before the trip I proceed to dilute the 25i-NBOMe with an alcohol solution of 500µg (micrograms) / ml. Therefore, each ml will provide a 500µg trip. I already have many experiences with 25i-NBOMe at 250µg (A bit on the low side), 500µg and 1 mg! It feels always safe!
The substance has no body-load or worrisome effects on the body except sometimes a “speedy” rush feeling. I attributed that being a 2C-I / DOI derivatives.
The day of the trip, my friend “G” come at 11:00 AM along with “J” which was the sober guardian. “G” was a bit anxious and excited for his trip; he never felt any change in consciousness expect an alcohol-buzz and marijuana (Which is smoke only 2 times).
I told him the effects and he read a bit online. I was preparing the food for the dinner (12:00AM). He confirmed that he was ready!
We proceed to eat the dinner, which were some potatoes, sausages and tomatoes. At 2:00 PM I told him how to take the substance, I told him that he need to hold the ml drop in his mouth until the effects kicks.
Being cautious, I shake the vial one more time to be sure that the chemical is evenly diluted in the vial. I carefully take out 1 ml with my seringue that contains 500µg. I gave the syringe to him and he drops the ml in his mouth. I did the same. We were sitting on the sofa, watching TV with “J” (the sober guardian).
“J” was drinking a beer so he was still able to keep an eye on us. We were looking at each other with a kind of smile, waiting for the effects. 45 minutes later the effects start to kick, “G” spit out his saliva in the trash bin, and I did the same. The trip is kicking!
“G” was telling that my living room seems weird and he was sure it was not the same living room as before. I told him that it was normal; it was due to the drugs and he just need to watch and enjoy!
As my side, my mouth was somewhat numb and the walls of my living room started to “breathes” (you know the common effects of psychedelics btw).
“G” kept repeating how weird the living room was, and how weird he feels. He was giggling, but I remarked that it was a nervous giggling. The word “weird” was his only word from now. He was staring at the walls and he seems to be confused, he look at his feet and he said something like: “Are we walking on water here?”
I told him that he has nothing to worry about and he just need to stay calm and everything will be fine. “J” was speaking to him, trying to get his attention.
I was somewhat surprised that “G” felt like this, because I thought the 25i-NBOMe was not that strong. 500µg seems fine, not too light, and not too strong. It’s like a “psychedelic mash-up” with the common trippy effects that LSD have (Maybe a bit speedier).
I was used to the 25I-NBOMe effects and they were very easy to handle, the mind stay very clear the whole time. “G” anyway feels not right and he rushed to the toilet, he vomited! He returns on the living room and he sat on the sofa. I told him to close his eyes and relax, he will feel better.
I was enjoying the experience so far, but I was concerned about “G” that was not right! “J” was looking at me somewhat disturbed. I was enjoying the visuals for a while, just watching everywhere. Everything was moving, swirling and melting in a very cool manner! I asked at “G” if he was ok, but he was not replying at all !
I told : “G” ?? Hey buddy ! Wake up, what’s wrong ?
“J” said he was not moving at all. Now something was not wrong with “G”. He was sit on the sofa, unable to reply, his eyes closed and his face was bright red!! I “slap” him gently on the face to wake him up ! “G” was unresponsive to external stimulus.
“J” ask to call medical attention. I said no and we should wait. I tried to talk to “G” but he was looking not well at all, his face was very bright red, almost blue – purple!! His breathing was faint, and his heart seems to sky rocketed.
I went to the kitchen, take a glass of water and try to make him drink the water. “J” cry at me: “CALL THE AMBULANCE HIS LIPS TURNED BLUES!!”
I begin to panic myself, I just say “NO” I don’t want to call hospital, I prefer to go there! With the help of “J” We picked up “G”. Oh gosh he can’t stand on his legs.
We caught him by the shoulders and we dropped him in the back seat of the car. “J” was driving us to the hospital.
[Erowid Note: Driving while intoxicated or tripping is dangerous and irresponsible because it endangers other people. Don't do it!] I really can’t believe what was happening! During the drive, “G” was kind of waking up and he was still saying how weird the things are. I tried to calm him down; telling him it will be ok.
We arrived at the hospital in the emergency parking. We were having problems carrying “G” so “J” rushed to the ER and ask for help. Some guys of the EMT runs to the car and then we were bombarded of questions: “What’s wrong ?” I told the person that we took 25I-NBOMe, that it was a hallucinogen drugs somewhat similar of 2C-I but he never heard of it!
The EMT staff carried him on a stretcher, put him an oxygen mask and rushed him to the emergency room. One of the guy ask if he was the only one to be on drugs. Since I was in fear I replied that I also took the drugs but I felt fine. He said I need to sit in the waiting room and if anything is going wrong, I can tell them. “J” was waiting with me.
I feel very anxious all the way but I can still stay coherent and manage my fear since I do not find the trip to be rude. Then a guy from the emergency room come and asked us some questions: “What kind of drugs did he took?” I told him it was a derivative of 2C-I that is a hallucinogen drugs. He said he only know 2C-B but not 2C-I.
He also sent someone to check my vitals. A woman came and proceeded to take my blood pressure and analyzing my heartbeat. I was bit panicking and I told her if everything is ok ? She told that my BP was OK but my heartbeat is beating somewhat fast but that is not dangerous.
I asked her if I can have some Valium or Xanax but she does not agree. I asked if my friend will be ok but they do not know. Someone told us that his Magnesium / Potassium level have drop down dangerously and that he could die at any moment during our trip!
They released me and my friend “J”.
As I wrote this trip report, my friend is still in the hospital… 5 days later!
I don’t know what happened, my friend don’t seem to have any circulatory, heart-disease! He is athletics and he is vegetarians! He was always fine before and rarely being ill. I’m kind of shaky because I never have such a reaction to 25i-NBOMe before, and my trip felt fine and clean all the time. So if you wanna digging into the Research Chemicals realm, please start very low and expect to everything coming!
I’m 100 % it will be better if we took Mushrooms or LSD, because they are more researched and they are very safe at least. Due to the unknown safety-profile of the 25X-NBOMe compounds being new on the market, I suggest strongly to consider taking
them.
Please be safe !

UNBREAKABLE A film review by Christopher Null Copyright 2000 filmcritic.com filmcritic.com
With the long-awaited release of M. Night Shyamalan's Unbreakable, the moviegoing world has one question on its mind: will it be unexpectedly great like his last film The Sixth Sense, or will it unexpectedly suck eggs like his first film Wide Awake?
Sadly, the answer is neither, though an overexcited populace spoon-fed on a year's worth of hype is likely to lean toward the latter owing to severe disappointment. It's hard to blame them.
This time out we're back to gloomy Philadelphia in a story about one David Dunne (Bruce Willis), a security guard who wakes up after a catastrophic train wreck to discover he is the sole survivor of the crash, with nary a scratch on his body. The next day David finds a cryptic note on his windshield, leading him to the Biblically-inspired Elijah Price (Samuel L. Jackson), a comic book dealer with a fragile bone disease that has crippled him. Elijah tries to convince David that he is possessed of superhuman strength and is, as the title suggests, "unbreakable."
David pooh-poohs the idea, but slowly he begins to accept the possibility that, yes, he can't be hurt, but he can lose his hair. Will Bruce become our first major superhero with male pattern baldness?
At this point, Unbreakable had me (and likely everyone else) wondering if I was in the right movie. From the trailers and the advance press, wasn't this supposed to be some kind of metaphysical exploration of the meaning of life and death, about how a man learned some secret of the universe that's eluded us for all these years, perhaps, all due to a fluke train crash?
Putting the story aside for a moment, Unbreakable is extremely competent in the hands of its crew, coming together on a slow burn as bit by bit of the story is revealed, just like in The Sixth Sense. Sure, it's a little overindulgent, as every other scene is photographed upside-down, reflected in a TV, or some other such trickery, but it keeps you interested in watching (and the superhero zaniness may incline you otherwise).
And just as you're about to get sucked in, there goes Jackson, being forced as if at knifepoint to utter lines like, "It's like kryptonite," with total seriousness. The mind begins to reel. The movie begins to suffer.  (Overheard from one Disney publicist during the screening: "It's one of those movies that grows on you." We'll see.)
Ultimately, Unbreakable is an extremely charming and well-produced film about something that's so silly and unbelievable it makes you wonder why people went to all the trouble to put it together. But ironically, Unbreakable could have worked extremely well as a real superhero movie. Say you change the title to The Protector and make it the story of a regular guy who suddenly finds out he's a superhero, and get rid of all the overwrought train crashes and such.
Or better yet, make it a movie called Unbreakable, and it's about a guy who learns the meaning of life and death... some secret of the universe that's eluded us for all these years.

PD: Alleged child abuser targeting teen girls on Phoenix buses arrested
by abc15.com staffPHOENIX — Phoenix police say an alleged child abuser who reportedly targeted teenage girls on city buses was recently arrested.
According to the Phoenix Police Department, 53-year-old Martin Huerta-Herrera was arrested for his alleged connection to assault cases.
Police officials say on November 15 around 7 a.m, Herrera was on a city bus near 35th Avenue and Camelback Road when he allegedly pushed his lower body against the hand of a teenage girl as she was getting off the bus. The interaction occurred over Herrera's clothing, and was not reported until the victim arrived at school, police say.
During the investigation, police made a connection to a similar incident that happened on April 24, 2017, during which a man was on a bus and put his hand on the thigh of a teenage girl over her clothing. The girl pushed the man's hand away, but he then reportedly grabbed her hand and forced her to "touch him over the clothing." Police said this incident also happened in the area of 35th Avenue and Camelback Road, but officers were unable to identify or locate the suspect at that time.
On November 21, officers spotted Herrera in the area of 35th Avenue and Thomas Road and noticed that he fit the description from the November 15 incident. Investigators also determined Hererra to be the suspect in the 2017 incident.
After taking Herrera into custody, police say he admitted to being the suspect in the video of both incidents during his interview.
Herrera was booked into jail and faces charges for sexual abuse for both the 2017 and 2019 incident.

step_discretize_xgb
creates a specification of a recipe step that will
discretize numeric data (e.g. integers or doubles) into bins in a
supervised way using an XgBoost model.
step_discretize_xgb( recipe, ..., role = NA, trained = FALSE, outcome = NULL, sample_val = 0.2, learn_rate = 0.3, num_breaks = 10, tree_depth = 1, min_n = 5, rules = NULL, skip = FALSE, id = rand_id("discretize_xgb") ) # S3 method for step_discretize_xgb tidy(x, ...)
| recipe | A recipe object. The step will be added to the sequence of operations for this recipe. |
|---|---|
| ... | One or more selector functions to choose which variables are
affected by the step. See |
| role | Defaults to |
| trained | A logical to indicate if the quantities for preprocessing have been estimated. |
| outcome | A call to |
| sample_val | Share of data used for validation (with early stopping) of the learned splits (the rest is used for training). Defaults to 0.20. |
| learn_rate | The rate at which the boosting algorithm adapts from
iteration-to-iteration. Corresponds to |
| num_breaks | The maximum number of discrete bins to bucket continuous
features. Corresponds to |
| tree_depth | The maximum depth of the tree (i.e. number of splits).
Corresponds to |
| min_n | The minimum number of instances needed to be in each node.
Corresponds to |
| rules | The splitting rules of the best XgBoost tree to retain for each variable. |
| skip | A logical. Should the step be skipped when the
recipe is baked by |
| id | A character string that is unique to this step to identify it. |
| x | A |
An updated version of recipe
with the new step added to the
sequence of existing steps (if any).
step_discretize_xgb()
creates non-uniform bins from numerical
variables by utilizing the information about the outcome variable and
applying the xgboost model. It is advised to impute missing values before
this step. This step is intended to be used particularly with linear models
because thanks to creating non-uniform bins it becomes easier to learn
non-linear patterns from the data.
The best selection of buckets for each variable is selected using an internal early stopping scheme implemented in the xgboost package, which makes this discretization method prone to overfitting.
The pre-defined values of the underlying xgboost learns good
and reasonably complex results. However, if one wishes to tune them the
recommended path would be to first start with changing the value of
num_breaks
to e.g.: 20 or 30. If that doesn't give satisfactory results
one could experiment with modifying the tree_depth
or min_n
parameters.
Note that it is not recommended to tune learn_rate
simultaneously with
other parameters.
This step requires the xgboost package. If not installed, the step will stop with a note about installing the package.
Note that the original data will be replaced with the new bins.

[gecode-users] About ArgumentSizeMismatch exception and linear constraint
Christian Schulte

The argument to the linear constraint (*.col(a)) defines the coefficients
for the variables in the second argument (*.row(d)). They must be of the
same size (same number of arguments), naturally. If not, an exception is
thrown.
Check the reference documentation of linear, it says in which cases linear
throws which exceptions.

Subject: [gecode-users] About ArgumentSizeMismatch exception and linear
constraint
Hi group,
Can you kindly give some hint on the possible relationship between linear
constraint and the ArgumentSizeMismatch expection?
My program is running under Virtual C++ 2008 Express Edition, and every time
I debug it. It will give below output with an arrow pointing to my linear
constraint in the editor. My linear constraint is as below:
linear(*this,scene_actor_matrix.col(a),shooting_day_and_scene_matrix.row(d),
IRT_EQ,sum,ICL_DEF);
And the exception message:
First-chance exception at 0x76a1b727 in NewSceneAllocation.exe: Microsoft
C++ exception: Gecode::Int::ArgumentSizeMismatch at memory location
0x001cf364..
Unhandled exception at 0x76a1b727 in NewSceneAllocation.exe: Microsoft C++
exception: Gecode::Int::ArgumentSizeMismatch at memory location 0x001cf364..
I also tried initializing the matrixes with proper domain and also checked
the size of the matrix. Still got the exception.
Thanks for your reply in advance.
Regards,
Yong

FatLineRenderer
Direct Subclass:
As you many know, line rendering with thickness is not well-supported in WebGL implementations (mostly due to WebGL implementations on Windows defaulting to emulating OpenGL calls via ANGLE on DirectX 9). Therefore lines are rendered using triangles. This greatly blows up the memory requirements as enough information needs to be passed to expand lines in the vertex shader to a constant thickness. See below:
@todo: we should probably see if some of this overhead can be reduced with drawElementsInstanced() or by cleverly aligning strides and or offsets.

PM\-POWERSAVE
Section: pm-utils User Manual (8)Updated: Mar 5, 2007
Index Return to Main Contents
NAME
pm-powersave - Put your computer into low power modeSYNOPSIS
- pm-powersave [{true | false}]
DESCRIPTION
pm-powersave can be used to set your system into low power mode.
OPTIONS
true
- Set the computer into low power mode to reduce energy consumption and extend your laptop's battery life.
false
- Turn off low power mode.
FILES
/etc/pm/power.d/, /usr/lib/pm-utils/power.d/
-
When you run
pm-powersave
it combines the scripts in these two directories and executes them in sorted order. If both directories contain a script with the same name, the one in /etc/pm/power.d/ has a higher precedence and only this one will be executed.
Therefore to disable a script from /usr/lib/pm-utils/power.d/ simply create an empty file in /etc/pm/power.d/ with the same name and without the execute bit set.

Your period is a sign of puberty. It means your body is growing and you are turning into an adult. This usually happens between ages 10 to 16 years. If your period hasn't started by the time you are 16, please consider seeing a doctor.
Not really. Our pads can quickly absorb your flow, leaving you dry and comfortable. No odours, we promise.
A period can last anywhere between 3 to 7 days.
Your period stops at the stage of menopause. This is usually when you cross 40 years of age.
Many women and girls suffer from irregular bleedings during their monthly menstrual cycles. Your period is irregular if it comes more frequently than 21 days, or you go 35 days or more between periods, the cycle length varies greatly. Sometimes irregular periods can be caused by some medicines, exercising too much, too low or too high body weight.
Your period stops at the stage of menopause. This is usually when you cross 40 years of age.
Using a sanitary pad is fairly easy. Just follow these simple steps -
Disposing off a sanitary pad correctly is important. Always wrap the used pad in a newspaper or toilet paper before placing it in the bin. Also check with your residential complex’s rules on correct ways to dispose of a sanitary pad.
If you’ve just started chumming, it might take a few tries before you know what menstrual hygiene products work best for you. It could be pads, it could be tampons, or even be a combination of both. Take your time, you’ll eventually learn about your flow patterns and be able to decide what to wear during your period.
As often as you like. Ideally, sanitary pads should be changed every six to eight hours but if you prefer to change pads more frequently, go for it.
To avoid rashes, keep the area between the thighs dry and clean. Wash your genital area properly with water and dry it after every time you go to the toilet. Always wipe from front to back direction after defecation to avoid infection. Change the pad after every 4-5 hours for hygiene and to avoid staining and foul odor. Keep yourself clean and bathe regularly.
While there are no reliable scientific studies on the subject, many women and doctors believe using pads over tampons can shorten your period. The idea is that products like tampons absorb menstrual blood, but they also cause a sort of backup within your vagina. Pads, on the other hand, allow blood to leave your body naturally and at a more normal rate. In theory, this could lead to shorter periods.
Aside from being reusable, menstrual cups work by collecting your flow, rather than absorbing it. As a result, they can be left in for longer than tampons and don’t leave you feeling as dried out.
Most folks can wear either size, but you might prefer size A if you’re new to cups, or if you have trouble inserting tampons. Choose size B if you’ve given birth or have a weak pelvic floor.
Clean the cup with warm water and a mild, unscented and oil-free soap, making sure the tiny holes under the rim are clear. Dry the cup completely before storing in the breathable cotton bag provided.
While unlikely, you may need to empty in public (especially if you have heavy flow). If you're uncomfortable exiting the stall to wash your cup, simply remove & empty as usual, then wipe it with toilet paper before reinserting.>
Inspect your cup regularly for signs of deterioration such as a sticky or powdery film, severe discoloration or odor, etc. If you detect any of these signs, or if you experience irritation, it's time to replace it! Once a year is a good rule of thumb.
 They work by absorbing fluids including menstrual blood. If you choose and use correctly, it can be the best mean of hygiene for you. It is recommended to renew a tampon every 4 to 8 hours in order to avoid toxic shock syndrome.
You don't need any special preparation for using a tampon. You can use it as soon as you get your first period, even if you are a virgin or not. Proper insertion is important for comfortable usage and avoiding any possible leaks.
Actually, there is no minimum age to start using a tampon. You may start using them as soon as you have the first menstruation. You can use them if you are a virgin as well. However, make sure that you have chosen a proper size and learned how to insert and take it out correctly.
You should change your tampon every 4 to 8 hours if you have medium intensity flow. Take care of yourself through proper hygiene and don't let the tampon to be inside for more than 8 hours.
Tampons are very popular hygiene products. If you correctly choose the size and insert it properly, you should not feel any discomfort. You actually should not feel it at all if the size is proper and it is inserted correctly.

XRouter
A simple routing library for iOS projects.
Usage
Basic Usage
Define Routes
enum Route: RouteType {
case homeTab
case login
case profile(withID: Int)
}
Create your Router
class Router: XRouter<Route> {
/* ... */
/// Configure the destination view controller for the route
override func prepareForTransition(to route: Route) throws -> UIViewController {
switch route {
case .homeTab:
return container.resolve(HomeTabCoordinator.self)?.rootViewController
case .login:
return container.resolve(LoginFlowCoordinator.self)?.startFlow()
case .profile(let id):
return ProfileViewController(withID: id)
}
}
}
Using a Router
// Create a router
let router = Router()
// Navigate to a route
router.navigate(to: .loginFlow)
// ... or open a route from a URL
router.openURL(url)
RxSwift Support
XRouter also implements reactive bindings for the RxSwift framework. Bindings exist for the navigate(to:)
method, which returns a Completable
event, as well as the openURL(_:)
method, which returns a Single<Bool>
event (indicating whether or not the url was handled).
router.rx.navigate(to: .loginFlow) // -> Completable
router.rx.openURL(url) // -> Single<Bool>
Advanced Usage
URL Support
You only need to do one thing to add URL support to your routes.
Implement the static method registerURLs
:
enum Route: RouteType {
/* ... */
static func registerURLs() -> URLMatcherGroup<Route>? {
return .group("store.example.com") {
$0.map("products") { .allProducts }
$0.map("products/{category}/view") { try .products(category: $0.param("category")) }
$0.map("user/{id}/profile") { try .viewProfile(withID: $0.param("id")) }
$0.map("user/*/logout") { .logout }
}
}
}
Here is an example with multiple hosts:
extension MyRoute: RouteProvider {
static func registerURLs() -> Router<MyRoute>.URLMatcherGroup? {
return .init(matchers: [
.group(["example.com", "store.example.com"]) {
$0.map("products/") { .allProducts }
$0.map("products/{category}/view") { try .products(category: $0.param("category")) }
$0.map("user/{id}/profile") { try .viewProfile(withID: $0.param("id")) }
$0.map("user/*/logout") { .logout }
},
.group("affiliate.website.net.au") {
$0.map("*/referral/") { .openReferralProgram(for: $0.rawURL) }
}
])
}
}
Then call the openURL method inside your URL handler. Here is Universal Links for example:
extension AppDelegate {
/// Open Universal Links
func application(_ application: UIApplication,
continue userActivity: NSUserActivity,
restorationHandler: @escaping ([Any]?) -> Void) -> Bool
{
guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
let url = userActivity.webpageURL,
let handledURL = router.openURL(url) else {
return false // Unrecognized URL
}
return handledURL
}
}
Handling errors
It can get messy trying to handle errors in every place you call navigate.
You can set a completion handler for an individual navigation action:
router.navigate(to: .profilePage(id: "12")) { (optionalError) in
if let error = optionalError {
print("Oh no, there was an unexpected error!")
}
}
If you handle all navigation errors in the same way, you could provide a wrapper. For example, something like this:
class Router: XRouter<Route> {
/* ... */
/// Received an error during
override func received(unhandledError error: Error) {
log.error("Oh no! An error occured: \(error)")
}
}
Custom Transitions
Here is an example using the popular Hero Transitions library.
Set the customTransitionDelegate
for the Router
:
router.customTransitionDelegate = self
(Optional) Define your custom transitions in an extension so you can refer to them statically
extension RouteTransition {
static var heroCrossFade: RouteTransition {
return .custom(identifier: "HeroCrossFade")
}
}
Implement the delegate method performTransition(...)
:
extension Router: RouterCustomTransitionDelegate {
/// Handle custom transitions
func performTransition(to viewController: UIViewController,
from sourceViewController: UIViewController,
transition: RouteTransition,
animated: Bool,
completion: ((Error?) -> Void)?) {
if transition == .heroCrossFade {
sourceViewController.hero.isEnabled = true
destViewController.hero.isEnabled = true
destViewController.hero.modalAnimationType = .fade
// Creates a container nav stack
let containerNavController = UINavigationController()
containerNavController.hero.isEnabled = true
containerNavController.setViewControllers([newViewController], animated: false)
// Present the hero animation
sourceViewController.present(containerNavController, animated: animated) {
completion?(nil)
}
} else {
completion?(nil)
}
}
}
And override the transition to your custom in your Router:
override func transition(for route: Route) -> RouteTransition {
switch route {
case .profile:
return .heroCrossFade
default:
return super.transition(for: route)
}
}
Documentation

Dave East Calls Out "Fake Blogs" Over Sales Predictions For 'Survival' Album
by Yohance Kyles (@HUEYmixwitRILEY)The Def Jam recording artist landed in the Top 15.
(AllHipHop News) Dave East needed to get some things off his chest. There were rumors circulating that his Survival album sold less than 3000 units in its first week of release.
When the official numbers came back, East saw his debut studio album pull in around 22,000 units to open at #11 on the Billboard 200 chart. The Harlem-bred emcee took to Instagram to call out media outlets that pushed the "poor sales" narrative.
The Wu-Tang: An American Saga actor wrote:
Thanks To The Real. All The Fake Blogs And Fake Projections The Frank Stand Is Open 24 Hours A Day And Please Never Reach Out For Another Interview Or Anything Involving Dave East. I’m Cool. Shouts To @billboard For The Facts...
Survival includes contributions from Teyana Taylor, Rick Ross, Nas, The-Dream, Fabolous, Gunna, Jacquees, Lil Baby, and Ty Dolla Sign. East and Taylor recently performed "Need A Sign" on The Late Late Show with James Corden.

Why Classes?
Why are Clases important in Ruby?
- Classes are a key component of object oriented programming and allow you to be modular and reuse often used methods in a repeatable way without the recreate the methods over and over again. Classes allow you to group functions, variables, and even other classes into one contained object that does not interfere with other objects.
- Classes in Ruby are first-class objects---each is an instance of class Class. Classes are the basic template from which object instances are created.
- A class is a blueprint or template or set of instructions to build a specific type of object. Every object is built from a class. Each class should be designed and programmed to accomplish one, and only one, thing.
- In summary, Ruby classes and Ruby objects are the foundation and building blocks of the programming language and you must learn how to create them in order to create a program based on Ruby.
Important Concepts and Definitions within Classes
- Instance Variables - Instance variables are created for each class instance and are accessible only within that instance. They are accessed using the @ operator. Outside of the class definition, the value of an instance variable can only be read or modified via that instance's public methods.
- Class Methods - Class methods are declared the same way as normal methods, except that they are prefixed by self, or the class name, followed by a period. These methods are executed at the Class level and may be called without an object instance. They cannot access instance variables but do have access to class variables. By default, all methods in Ruby classes are public - accessible by anyone. Here are the different types of methods
- Public method can be accessed from anywhere
- Private method can only be accessed within the class itself. A private method cannot be called outside class scope.
- Protected method can be accessed within the same file and subclasses.
- Instantiation - An object instance is created from a class through the a process called instantiation. In Ruby this takes place through the Class method new.
What are the benefits using Classes?
- Classes are useful to use when you want to give methods to your data or have multiple instances of your data. Classes provide efficiency and reusability
- Classes allow you to reuse commonly used code. They save you the trouble of having to rewrite (and overwrite!) all those lines of code that were already taken care of by your class

In spite of its association with Denmark, Greenland is not a member of the EU and therefore all arriving boats must follow the usual clearance procedure and make their first stop at a port of entry.
Contact the port authorities well in advance of arrival for special permission to enter the ports, if possible 24 hours beforehand on VHF Channels 12 or 16.
Last updated November 2015.
All visitors must have a valid passport.
Greenland is neither a member of the European Union nor a member of the Schengen Agreement Area, but its visa requirements are similar.
For visitors wishing to explore the glaciers and mountains or visit the national park view this website www.eastgreenland.com.

The importation of firearms is forbidden.
Note: Special permission is needed to export souvenirs of whales’ teeth and walrus tusks. Authorisation forms are available from shops and tourist offices.
Import of fresh food is prohibited.

A head-net is essential if ashore during the summer (especially July) to prevent the clouds of mosquitoes, midges and mini-flies getting into eyes, noses and ears. Such nets are widely sold in Greenland.
The military areas of Gronnedal Fladestation (naval base), Thule Air Base and Sondre Stromfjord Air Base are prohibited for yachts. All military areas must be avoided.

Samples data.
If this function is not available, you must install the Analysis ToolPak add-in.
Syntax
SAMPLE(inprng, outrng, method, rate, labels)
SAMPLE?(inprng, outrng, method, rate, labels)
Inprng is the input range.
Outrng is the first cell (the upper-left cell) in the output column or the name, as text, of a new sheet to contain the output column. If FALSE, blank, or omitted, places the output table in a new workbook.
Method is a text character that indicates the type of sampling.
If method is "P", then periodic sampling is used. The input range is sampled every nth cell, where n = rate.
If method is "R", then random sampling is used. The output column will contain rate samples.
Rate is the sampling rate, if method is "P" (periodic sampling). Rate is the number of samples to take if method is "R" (random sampling).
Labels is a logical value.
If labels is TRUE, then the first row or column of inprng contains labels.
If labels is FALSE or omitted, all cells in inprng are considered data. Microsoft Excel generates appropriate data labels for the output table.

Viral- Navjot Singh Sidhu calls Imran Khan ‘lion,’ Pakistani PM asks, “where’s our Sidhu?”
by JKR StaffFormer India cricketer and Punjab minister, Navjot Singh Sidhu, recently travelled to Pakistan to take part in the inauguration of the much-anticipated Kartarpur corridor for Sikh pilgrims. Speaking at the event, Sidhu showered praises on his former cricketer friend, now Pakistan’s PM, for respecting the sentiments of 14 crore Sikhs.
Speaking at the event in the presence of Khan, Sidhu said that Sikhs could not repay the debt of the Pakistani prime minister for his generosity.
Meanwhile, a video of Khan inquiring about his friend Sidhu while taking a bus to visit the inauguration venue has gone viral on social media. In the video, Khan is seen asking his aides, “where’s our Sidhu? I am saying ‘our Sidhu.’ Has he arrived?”
Prime Minister Narendra Modi on Saturday flagged off the first batch of over 500 Indian pilgrims led by Akal Takhat Jathedar Giani Harpreet Singh to Gurdwara Darbar Sahib through the corridor.
The corridor was thrown open for devotees coinciding with the 550th birth anniversary of Sikhism founder Guru Nanak Dev. Speaking on the occasion, the Pakistani prime minister also raised the issue of human rights violations in Jammu and Kashmir.

The GtkEditable interface is an interface which should be implemented by text editing widgets, such as GtkEntry and GtkSpinButton. It contains functions for generically manipulating an editable widget, a large number of action signals used for key bindings, and several signals that an application can connect to to modify the behavior of a widget.
As an example of the latter usage, by connecting the following handler to “insert-text”, an application can convert all entry into a widget into uppercase.

“changed”
signalvoid user_function (GtkEditable *editable, gpointer user_data)
The ::changed signal is emitted at the end of a single user-visible operation on the contents of the GtkEditable.
E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

Overview
For my final project in CSC 572 (Grad Computer Graphics), I chose to implement the Transvoxel Algorithm.
"The Transvoxel Algorithm is a method for seamlessly stitching together neighboring triangle meshes generated from voxel data at differing resolutions so that level of detail (LOD) can be used with large voxel-based datasets such as volumetric terrain in next-generation video games." - Eric Lengyel
This algorithm was invented by Eric Lengyel back in 2009 and published in 2010. For my implementation, I wanted to procedurally generate voxelized terrain with various levels of detail (LOD) that was fully destructible in real-time.
But before I dive into the implementation, let's look at some background...

Procedural Generation
Procedural generation is the process of a computer generating content rather than a human artist or designer. This alleviates much of the time and money spent on hiring human artists and has the potential to quickly create a vast amount of interesting content. For this assignment, I wanted to procedurally generate terrain. To do this, I used an algorithm called Simplex Noise. You may have heard of its predecessor, Perlin Noise. Both were created by the same man, Ken Perlin, but Simplex Noise is known to be faster, have fewer artifacts, and work at higher dimensions.
To generate terrain using Simplex Noise, either 2D or 3D Noise can be used...
2D Noise
To generate terrain using 2D Simplex Noise, people use what's called a 2D heightmap. This is basically a grayscale image where the pixel intensities correspond to the heights of the terrain vertices. If you have a 256x256 image, then your terrain will have 256x256 vertices and will be a perfect square. The 2D heightmap is generated using Simplex Noise by sampling the noise function at each pixel location (x, y) and storing the result in the heightmap. Using just the values from the noise algorithm may give seemingly random noise, but following a process called Fractal Noise can give very realistic heightmaps.
|
Simplex Noise |
Fractal Perlin Noise |
One of the limitations of using 2D heightmaps is that no overhangs, vertical cliffs, or caves can be created, which limits the realism that can be achieved. This is fixed if we use 3D Simplex Noise.
3D Noise
To generate terrain using 3D Simplex Noise, the same process is followed as for the 2D noise, except we use a 3D grid of values (x, y, z). However, now the values can't correspond to the height of terrain vertices. Instead, each value corresponds to an isovalue of the 3D terrain surface. An isovalue is 0 if it lies exactly on the surface, negative if it is within the terrain, and positive if it is outside of the terrain. A simple example is a sphere. The isovalues in a 3D volume correspond to the distance from the surface of the sphere, with 0 being on the surface, negative values being within the sphere, and positive values being outside of the sphere.
|
3D Noise |
3D Noise w/ Voxel Cubes |
To generate triangles from a volume of isovalues, several methods exist: Marching Cubes, Surface Nets, Dual Contouring, and maybe others. For this implementation, I used Marching Cubes. A good tutorial page with code examples can be found here.
|
Marching Cubes |
And now we have voxelized terrain! YAY! :D
This is where Transvoxel comes in...
Transvoxel Algorithm
The Transvoxel Algorithm can be split into several steps:
Modified Marching Cubes (Ch 3)
The first step was to implement a modified version of Marching Cubes that fixed some inconsistencies with the original tables that could create holes in the terrain in certain situations. Eric Lengyel provides the modified tables here. It was pretty straightforward to implement this. Pretty much just implement Marching Cubes, but use these tables instead.
High Performance Implementation
Eric Lengyel also went over a high performance implementation that focused on reusing as many vertices as possible and sectioning the terrain into 16x16x16 blocks. I don't think it would be too difficult to implement this part, but I ran out of time and skipped it as it was not necessary for my simple implementation.
Level of Detail (LOD) (Ch 4)
The second step was to use LOD to simplify the terrain geometry and reduce the number of triangles being rendered based on distance from the viewer. Each LOD reduced the resolution of the volume by a factor of 2 in each dimension. This was required in order for the Transvoxel Algorithm to work properly. In general, the highest resolution LOD would be used within the closest proximity to the viewer. The farther away you go, the lower resolution the LOD would be. Each block of 16x16x16 voxels would be a single LOD. When changing the LOD, the block would resize to contain 16x16x16 voxels at the new resolution.
|
LODs |
In my implementation, to showcase the LOD, I just decreased the resolution of the LOD halfway along the Z axis. This allowed me to not worry about using blocks of voxels and to not worry about varying the LOD relative to the viewer's location.

LOD 0 Hole |
LOD 1 Hole |
LOD 2 Hole |
|
LOD 0 Hole Wireframe |
LOD 1 Hole Wireframe |
LOD 2 Hole Wireframe |
Surface Shifting
When rendering the terrain for 2 LODs, the transition between the two LODs will usually have a hole. This is due to the sampling of the isovalues for a voxel only occurring at the corners and generating the triangle vertices based upon these values. IMAGE. The triangle vertices will vary depending on the LOD used. To remedy this problem, when calculating the triangle vertex position along an edge of a lower resolution LOD, we recurse on that edge to sample the isovalues at higher resolutions in order to precisely choose the triangle vertex location. This fixes the issue where changing LOD can cause the terrain to shift up or down, which can physically move objects that were sitting on the terrain and look bad from a viewer perspective. With this fix, even at lower resolution LODs, the terrain should not shift its position.

LOD 1 Hole w/ Surface Shifting |
LOD 2 Hole w/ Surface Shifting |

LOD 0 Hole w/ Surface Shifting Wireframe |
LOD 1 Hole w/ Surface Shifting Wireframe |
LOD 2 Hole w/ Surface Shifting Wireframe |
Transvoxels (Ch 4)
The final step was to fill the holes generated from the LOD by using transition cells (transvoxels). This replaced any voxel along a lower resolution LOD boundary with 2+ voxels depending on how many sides were surrounded by higher resolution LOD (1 + #sides). The original voxel would still generate triangle vertices like normal, except it would only take up half of the space in whatever dimension the LOD boundary was. The other half of the space (the half closer to the higher resolution LOD) would be filled by a transvoxel.
|
Transition Cell Diagram |
A transvoxel consists of 13 points instead of the normal 8 (1 per corner). There are 9 points along the higher resolution LOD face, and 4 along the lower resolution LOD face. But the weird thing is that the 4 points along the lower resolution LOD face are actually the same isovalues as the 4 corners of the higher resolution LOD face. This allows much fewer possible configurations (512), which allowed Eric Lengyel to compute all possible vertex orientations for each configuration and put them into a table, just like for the Marching Cubes. The transvoxel tables are provided here.
|
Transition Cell |
Using the transvoxel tables, the process to generate triangle vertices is the same as for the normal Modified Marching Cubes. The amount of space the transvoxel takes up within the original voxel can be whatever you want, but Eric Lengyel recommended a value of 0.5 to ensure shading is normal and that no harsh changes in elevation occur in order to fill the holes.

LOD 0 Transvoxels - No Holes |
LOD 1 Transvoxels - No Holes |
LOD 2 Transvoxels - No Holes |
|
LOD 0 Transvoxels - No Holes Wireframe |
LOD 1 Transvoxels - No Holes Wireframe |
LOD 2 Transvoxels - No Holes Wireframe |
Concavity Fixing
Even with the transvoxels correctly filling the holes, there can still be artifacts in the sense of concavities where the transvoxels are created. Instead of the geometry smoothly transitioning from one LOD to the next, a small concavity appears at the transition boundary. Eric Lengyel uses a linear transformation in order to fix this, but I was not able to get it working before the end of my project.

Shading / Texturing (Ch 5)
Unfortunately, I didn't get this far... But it essentially used triplanar texturing and normal mapping to create pretty cool shading / texturing.

Triplanar + Normal Mapping |
Terrain Editing
The Transvoxel Algorithm does not describe how to edit the terrain in detail, so I decided to implement my own method editing tool. The simplest tool I could think of was to cast a ray in the direction the camera is facing and to create a hole or create a column in that direction for each voxel that intersected the ray. When using a voxel volume of 64x64x64, it took a couple seconds to calculate this intersection for every voxel, so I sped it up by using a naive Octree space partition to detect voxel intersections with the ray. This sped it up by a factor of 100, which was adequate for real-time modifications.

Conclusion
The transvoxel algorithm was pretty fun to implement, and has many applications in video games. I would have liked to implement the optimizations discussed in the paper as well, but I am pretty satisfied with the results I achieved. I used a 64x64x64 voxel volume for my implementation, but would have liked to try much larger volumes with LOD enabled, since LOD allows for vast landscapes to be rendered with much less computational overhead.

PICTURE PERFECT
Former world champion boxer paints statue portrait of Celtic legend McNeill
by David FowlerFORMER two-time world champion boxer Scott Harrison has painted a portrait of the iconic Billy McNeill statue outside Celtic Park.
The ex-WBO featherweight champ traded in the gloves for the paintbrush as he painted various sporting icons.
Celtic fans have been blown away by one of his latest pieces which captures the iconic Billy McNeill statue outside Parkhead.
Posting a picture of the art, he wrote: "Painting I started yesterday, no painted in months.
"Prints now available on all my paintings also signed !
"Check out my Scott Harrison Art page on Insta and Facebook for prices or message me if you want a painting done !👍🥊🎨"
The piece shows the statue glowing at night with the lights of Celtic Park in the background.
Lisbon Lions legend McNeill died in April this year.
He passed away just two years after his family revealed he was battling dementia.
The Hoops icon was the first British player to lift the European Cup and the club's greatest captain.
Hoops supporters were quick to salute Harrison's painting as they responded to the boxer.

Harrison has also painted other sporting stars as he shared a piece of Floyd Mayweather this week.
While Neil Lennon, Steven Gerrard, Sir Alex Ferguson and Billy Connolly have also been the subject of past paintings.
Prints are available of both pictures through Instagram and Twitter.
Harrison first became WBO featherweight champion in 2002.
He lost the belt in July 2003, but re-captured the gold in November of the same year.

Concurrency.simutime
Syntax
simutime : int
Description
The simutime function returns the number of simulated time units that have passed since program execution began.
Details
Simulated time only passes when all process are either paused or waiting. This simulates the fact that CPU time is effectively infinitely faster than "pause" time.
Example
This prints out the simulated time passing between two processes. This will print out 3, 5, 6, 9, 10, 12, 15, 15, 18, 20, 21, ...
process p (t : int)
loop
pause t
put simutime
end loop
end p
fork p (3)
fork p (5)
Status
Exported unqualified.
This means that you can call the function by calling simutime or by calling Concurrency.simutime.

The first thing we need to remember is that a floating element is shifted either to the left or to the right. It is not possible to make an element float in the centre, something that often is frustrating for beginners. The basic rule is that a floating element is only shifted sideways. Elements following a floated element will wrap around the floated element. If you do not want this to occur, you can apply the “clear” property to these following elements. The four options are
clear: left, clear: right, clear: both or clear: none.
