public class CompletableFuture<T> extends Object implements Future<T>, CompletionStage<T>
Future
that may be explicitly completed (setting its
value and status), and may be used as a CompletionStage
,
supporting dependent functions and actions that trigger upon its
completion.
When two or more threads attempt to
complete
,
completeExceptionally
, or
cancel
a CompletableFuture, only one of them succeeds.
In addition to these and related methods for directly
manipulating status and results, CompletableFuture implements
interface CompletionStage
with the following policies:
ForkJoinPool.commonPool()
(unless it does not support a parallelism level of at least two, in
which case, a new Thread is created to run each task). To simplify
monitoring, debugging, and tracking, all generated asynchronous
tasks are instances of the marker interface CompletableFuture.AsynchronousCompletionTask
. CompletableFuture also implements Future
with the following
policies:
FutureTask
) this class has no direct
control over the computation that causes it to be completed,
cancellation is treated as just another form of exceptional
completion. Method cancel
has the same effect as
completeExceptionally(new CancellationException())
. Method
isCompletedExceptionally()
can be used to determine if a
CompletableFuture completed in any exceptional fashion.get()
and get(long, TimeUnit)
throw an
ExecutionException
with the same cause as held in the
corresponding CompletionException. To simplify usage in most
contexts, this class also defines methods join()
and
getNow(T)
that instead throw the CompletionException directly
in these cases.| Modifier and Type | Class and Description |

"Health Care is one of the most important fields AI gonna transform" Sundar Pichai - CEO ALPHABET So, We want to inspire developer community to develop AI for Good. Asia is lacking far behind in health care as compared to other developed countries. But now everyone has the power of changing that using AI. AI can be the best assistant of doctors in enormous cases, from helping them automate several scans and also giving best recommendations to patients. The scope of AI in health care is not just limited to doctors. It can also empower biologists and chemists to create more effective drugs or medicine based on specific type of disease. It can also lead us to try molecular level programming that will one day be a part of us saving us from different epidemics.

2.18.14 LHC


Total Dosages throughout the night:
Methylphenidate(Concerta)=216mg (108mg Oral, 108mg Snorted)
Cannabis=1 pipe bowl(glass pipe)
Opium=1 pipe bowl(smokedat same time with Cannabis)
Setting:
Parents are out for entire night drinking/partying with freinds.
My Brother is out with his freinds and I have no idea when he will return. He's 13y/o and doesn't use any drugs but doesn't mind if I do. So house is to myself for the most part and it's a Friday night.
About Me:
I'm 16y/o, about 6ft tall and 184lb. My drug history consists of Cannabis, Opium, most all of other opiates, except herion, DXM, LSD, Mushrooms, Adderall, Diphenhydramine, Alcohol, and some others I left out. My mood is happy, relaxed, and just all around good. I've done Methylphenidate numerous times before just not as high dosage.
Experience:
At 4:20 P.M. ;-), I cut 2 Concerta 54mg pills in half getting rid of the green sponge part. I swallowed the 2 white halfs with a glass of water.
4:35: I feel the first effects of the Methylphenidate.  Right away my chest gets warm and tingly.  My mental awareness is at its maximum. I feel very energetic, warm, and euphoria. I feel like a million bucks!
5:00: Going great! I feel so happy, I'm just going around the house to walk. The music is on and is awesome. I pet my dog, he seems as happy as me!
5:30: Same effects as before but little stronger. I think the 108mg I took orally is nearing its peak. It's like the Methylphenidate is coming in waves or intervals, it just feels so good.
6:00: I got my pipe, Cannabis, and some Opium I plan to smoke in a short while. I read up and asked some freinds and it would be fine to mix the Opium with Methylphenidate.
6:15: I have my pipe packed, with a little opium on top of the weed. The Methylphenidate has peaked for sure and is staying steady. I now leave to smoke in my garage. I shall return!
6:38: Just got back, The high is great, usually with weed and opium I get really lazy and barely move, but now I feel very energetic, incredibly happy, high euphoria, also body high is amazing.
7:15: I ate some Oreo's and milk and it went down very nicely. I can actually feel the ritalin through the THC and opium. Still energetic, no feel for sleep at all. Playing rave techno music and I'm dancing to it. I feel like a Billion bucks now!
7:53: I can tell the Methylphenidate is starting to come down. Not as energetic, and just don't feel the unique buzz of the Methylphenidate as strong anymore. The Opium is going down to. The pot is still keeping a strong buzz, which is making the Methylphenidate comedown much easier to handle.
8:00: I feel easily agitated, I have the urge to do more Methylphenidate. I don't wanna return to baseline. The THC stills feels great though! It's keeping my mood happy as I still comedown on Methylphenidate.  I'm also having weird stomach feelings, they're not painful or anything they just feel weird and kinda tickle.
8:41: Well the Opium is pretty much worn off, it usally only lasts about 2 hours with me. The THC is still buzzing pretty good and the Methylphenidate is coming down slower than usual.  My heart beat average so far has been about 100BPM. I'm really thinking about snorting or swallowing another 54 mg.
9:00: My girlfriend called and is coming over.  This has actually put a mood lift knowing that shes coming over. And my brother is gonna sleep at a friends house for the night.
9:20: Well the Opium is gone, the THC is hanging in there and the ritalin has comedown. My girlfriend has arrived and I crushed her 2-54mg pills and she sniffed both. She said almost right away she could feel a buzz coming on.
9:43: I couldn't resist, I snorted one more 54mg, I got the warm chest again, the increased mood, ebergy, and mild euphoria. My girlfriend seems talkative, energetic, and I think both of us have increased sex drive :-).
10:00: My girlfriend and I made out a little which really does seem better on Methylphenidate. The buzz is going pretty good for only 54mg. My girlfriend wants to have sex, but I don't wanna because I'm afraid my heartrate will increase way to much. It's going steady at 100BPM, sometimes jumping to 120-110BPM.
10:43: During the last 43 mins. I relaxed on my bed as I let my girlfriend masturbate me for a about 15 mins. I could really feel my heart going and the sensitivity was increased but not by much. Though then I masturbated my girlfriend and either I seemed to do a better job or she felt much more sensitive.
10:50: We've decided to go to her house and spend the night there.
Summary:
It was a great expierence! Doing other drugs while doing Methylphenidate was fun to try. But I would rather just take Methylphenidate alone then with other drugs.

vignettes/BuildingEnsembleModels.Rmd
BuildingEnsembleModels.Rmd
Ensemble models combine several models to improve the overall performance. Traditionally, weak learners were combined to boost performance but recent results show that combining several strong approaches can also result in a better performance. There are many examples in literature where ensemble models outperform individual models using stacking, i.e. a final logistic regresssion layer accross the individual model outputs, but other approaches like weigthing has also shown promising results.
This vignette describes how you can use the Observational Health Data Sciencs and Informatics (OHDSI) PatientLevelPrediction
package to build ensemble models. This vignette assumes you have read and are comfortable with building single patient level prediction models as described in the BuildingPredictiveModels
vignette.
This will enable studying ensemble methods at scale in the OHDSI data network.
In PatientLevelPrediction package, four ensemble strategies have been implemented:
Use the PatientLevelPrediction
package to generate a population
and plpData
object. Alternatively, you can make use of the data simulator. The following code snippet creates a population of 12000 patients.
data(plpDataSimulationProfile)
set.seed(1234)
sampleSize <- 2000
plpData <- simulatePlpData(
plpDataSimulationProfile,
n = sampleSize
)
population <- createStudyPopulation(
plpData,
outcomeId = 2,
binary = TRUE,
firstExposureOnly = FALSE,
washoutPeriod = 0,
removeSubjectsWithPriorOutcome = FALSE,
priorOutcomeLookback = 99999,
requireTimeAtRisk = FALSE,
minTimeAtRisk = 0,
riskWindowStart = 0,
addExposureDaysToStart = FALSE,
riskWindowEnd = 365,
addExposureDaysToEnd = FALSE,
verbosity = "INFO"
)
Specify the prediction algorithms to be combined.
# Use LASSO logistic regression and Random Forest as base predictors
model1 <- setLassoLogisticRegression()
model2 <- setRandomForest()
Specify a test fraction and a sequence of training set fractions.
testFraction <- 0.2
Specify an ensembleStrategy to combine multiple predictors. The strategy used for ensembling the outputs from different models, it can be ‘mean’, ‘product’, ‘weighted’ and ‘stacked’: ‘mean’ the average probability from differnt models ‘product’ the product rule ‘weighted’ the weighted average probability from different models using train AUC as weights. ‘stacked’ the stakced ensemble trains a logistics regression on different models.
ensembleStrategy <- 'stacked'
Specify the test split to be used.
# Use a split by person, alterantively a time split is possible
testSplit <- 'person'
Run the ensemble learning to combine model1 and model2. You can also use different plpData for different models.
ensembleResults <- PatientLevelPrediction::runEnsembleModel(population,
dataList = list(plpData, plpData),
modelList = list(model1, model2),
testSplit=testSplit,
testFraction=testFraction,
nfold=3, splitSeed=1000,
ensembleStrategy = ensembleStrategy)
You can save and load the model using:
saveEnsemblePlpModel(ensembleResults$model, dirPath = file.path(getwd(), "model"))
ensembleModel <- loadEnsemblePlpModel(getwd(), "model")
plpData <- loadPlpData("<data file>")
populationSettings <- ensembleModel$populationSettings
populationSettings$plpData <- plpData
population <- do.call(createStudyPopulation, populationSettings)
Load the model.
ensembleModel <- loadEnsemblePlpModel("<model folder>")
Get the predictions by applying the model:
prediction <- applyEnsembleModel(population,
dataList = list(plpData, plpData),
ensembleModel = ensembleModel)$prediction
Considerable work has been dedicated to provide the PatientLevelPrediction
package.

Google was officially launched in 1998 by Larry Page and Sergey Brin to market Google Search, which has
become the most used web-based search engine. Larry Page and Sergey Brin, students at Stanford
University in California, developed a search algorithm at first known as "BackRub" in 1996, with the
help of Scott Hassan and Alan Steremberg.
The search engine soon proved successful and the expanding company moved several times, finally settling
at Mountain View in 2003. This marked a phase of rapid growth, with the company making its initial
public offering in 2004 and quickly becoming one of the world's largest media companies.
The company launched Google News in 2002, Gmail in 2004, Google Maps in 2005, Google Chrome in 2008, and
the social network known as Google+ in 2011 (which was shut down in April 2019), in addition to many
other products. In 2015, Google became the main subsidiary of the holding company Alphabet Inc.

Davido, Wizkid, Others Shower Burna Boy With Praises After Grammy Awards Nomination
In the list released on Wednesday, Burna’s ‘African Giant’ album was nominated in the ‘Best World Music category.’
by SaharaReporters, New York
Leading Nigerian musicians have continued to shower praises on Hip-hop artiste – Damini Ogulu popularly known as Burna Boy – after he was nominated for the 2020 Grammy Awards.
In the list released on Wednesday, Burna’s ‘African Giant’ album was nominated in the ‘Best World Music category.’
The nomination is for albums containing at least 51 per cent playing time of new vocal or instrumental world music recordings.
Celebrating with the artiste over the feat, Banky W in a tweet said, “Our African giant has been nominated for a Grammy!
“Congratulations to @burnaboy, his mom and the entire team.
“Amazing and well deserved. Anything is possible with a little bit of faith and a lot of hard work. So happy for him.”
Also reacting to the announcement, ace music producer, Don Jazzy, said, “Congrats to the African giant @burnaboy on the Grammy nomination.
“Congrats on having the most amazing couple of years. The Grammy is actually just the icing on the already juicy cake.”
Adding his voice to the flurry of encomiums for Burna, Davido said, “Congrats @burnaboy, you deserve more than a nomination.”
It was the same for Wizkid, who said, “King Burna!! Congratulations blood! You deserve everything and more.”
Burna Boy is nominated in the same category with Altin Gün (GECE); Bokanté and Metropole Orkest Conducted By Jules Buckley (What Heat); Nathalie Joachim With Spektral Quartet (Fanm D’Ayiti) and Angelique Kidjo (Celia).

Lyrics of Love and Laughter
by Paul Laurence Dunbar
This is a collection of poetry by African American author Paul Laurence Dunbar. Dunbar's work frequently features a conversational tone, innovative rhetorical structure, and a colorful use of both dialect and mainstream English. Dunbar was among the first nationally successful African American writers.

Bharadwaj Giridhar is the founder and principal content creator of Foodmux. He created foodmux in 2017, after finding some cool restaurants in Madurai India, with no channels at that time covering these restaurants. With little help from his friends he was able to setup the channel and cover videos across Tamil Nadu. He is now amping up the channel to an app where people can share their love for food.

I just noticed that a new whitepaper was published recently by the BizTalk team called "Writing Effective BizTalk Server Adapters" [through luke nyswonger]. Strongly recommended if you are writing custom adapters, as the whitepaper explains the not-so-obvious sides of how the messaging engine works and how the different types of adapters should behave. It also contains valuable tips on how to ensure your adapters work reliably and with good performance.


PubhD started in Nottingham in January 2014 and this website is mainly dedicated to Nottingham’s events. However, the idea is spreading.
If your city is not listed below, why not start a PubhD yourself? You don’t have to be connected to a university to run a PubhD – at PubhD Nottingham we aren’t! See “How to set-up a PubhD (and get some speakers)” for some tips on how to get started. And get in touch – we’ll try to help!

This is a quick tip for all developers out there that want free private git hosting. You will need Dropbox (Referral link) or Google Drive. For the purpose of this example, we will use Dropbox.
 Create a directory named git if you don’t have one already:
{% highlight bash %} ~/your-project $ cd ~/Dropbox/ ~/Dropbox/ $ mkdir git ~/Dropbox/ $ cd git {% endhighlight %}Initialize a bare git named your-project.git and change directory back to your project.
{% highlight bash %} ~/Dropbox/git $ git init --bare your-project.git ~/Dropbox/git $ cd ~/your-project {% endhighlight %}Add the drop remote to your project. Instead of using the standard remote name of origin, use dropbox. This way it ensures if you ever want to add a second remote location, you can still name it origin.
{% highlight bash %} ~/your-project $ git remote add dropbox ~/Dropbox/git/your-project.git ~/your-project $ git push -u dropbox master {% endhighlight %}Once the remote is set, we push the previously committed changes. And that is all, now your git repo will be in the cloud as a backup and for free.
For Google Drive, the steps to follow are the same, except of using the Dropbox folder, you will use the Google Drive folder. The Google Drive sync app needs to be installed and downloaded.

About
My name is Kenny Leung. My technical background is in artificial intelligence, and I'm keen on learning new things everyday. I recently joined Twitter Cortex to explore problems at the intersection of NLP and machine learning! Prior to this, I worked on speech recognition at Google.
This personal site is meant for jotting down some interesting and/or useful ideas, musings, and insights that I gather at work and in my spare time. There is so much I have yet to explore, so I hope that this blog will be a good place to track my progress and share a little bit about what I'm learning. Thanks for visiting!


In life, we put the most weight on the word cooperation.
On-site work is the combination of planning, analysis, design, and testing, and resulting in a single result. That's why it will be difficult to predict what problems will occur and where. Separating responsibilities and avoiding when these problems arise in the field will make things impossible. Therefore, we think that all processes in the field are like gears, so we communicate and cooperate in all matters to minimize problems and losses.


Expiration keeps a region’s data fresh by removing old entries and entries that you are not using. You can choose whether expired entries are invalidated or destroyed.
Expiration activities in distributed regions can be distributed or local. Thus, one cache could control expiration for a number of caches in the system.
This figure shows two basic expiration settings for a client/server system. The server (on the right) populates the region from a database and the data is automatically distributed throughout the system. The data is valid for only one hour, so the server performs a distributed destroy on entries that are an hour old. The client applications are consumers. The clients free up space in their caches by removing their local copies of the entries for which there is no local interest (idle-time expiration). Requests for entries that have expired on the clients will be forwarded to the server.
Expiration Types
Apache Geode provides two types of expiration, each triggered by a time-based threshold. These can co-exist; they are not mutually exclusive.
- Time to live (TTL). The amount of time, in seconds, the object may remain in the cache after the last creation or update. For entries, the counter is set to zero for create and put operations. Region counters are reset when the region is created and when an entry has its counter reset. The TTL expiration attributes are
region-time-to-live
andentry-time-to-live
. - Idle timeout. The amount of time, in seconds, the object may remain in the cache after the last access. The idle timeout counter for an object is reset any time its TTL counter is reset. In addition, an entry’s idle timeout counter is reset any time the entry is accessed through a get operation or a netSearch . The idle timeout counter for a region is reset whenever the idle timeout is reset for one of its entries. Idle timeout expiration attributes are:
region-idle-time
andentry-idle-time
.
Expiration Actions
Apache Geode provides the following expiration actions:
- invalidate (default) - The data item’s value is deleted, but the key remains in the cache. Applies to all distributed members in which the data item is replicated.
- destroy - The data item’s key and value are both deleted. Applies to all distributed members in which the data item is replicated.
- local invalidate - Deletes the data item’s value. Applies only to the local member.
- local destroy - Deletes the data item’s key and value. Applies only to the local member.
You cannot use local-destroy
or local-invalidate
expiration actions in replicated or partitioned regions. You can use the local options only on distributed regions with a data-policy of empty, normal or preloaded.
Entry Expiration in Replicated Regions and Partitioned Regions
In replicated regions, entry updates are performed in the most convenient available copy of the data, then replicated to the other members, resetting their last-updated statistics to the same time. In partitioned regions, entry updates are always done in the primary copy, resetting the primary copy’s last-updated and last-accessed statistics, then the secondary copies are updated to match.
In both replicated and partitioned regions, entry retrieval uses the most convenient available copy of the data, which may be any of the distributed copies. Retrievals are not propagated to other members. Differences in last-access times are reconciled when the data item is considered for expiration.
Expiration can be triggered in any copy of a replicated region, if the time elapsed since the last update or read access exceeds the established threshold. Expiration in partitioned regions is executed in the primary copy, based on the primary’s last-accessed and last-updated statistics. In both cases, the expiration mechanism checks the last-accessed dates of all copies of the data item and updates the last-access date of all copies to the most recent last-accessed date. Then, if the elapsed time still puts the data item over the expiration threshold, the item is deleted in accordance with the expiration action specified for the region.
Interaction Between Expiration Settings and netSearch
Before netSearch
retrieves an entry value from a remote cache, it validates the remote entry’s statistics against the local region’s expiration settings. Entries that would have already expired in the local cache are passed over. Once validated, the entry is brought into the local cache and the local access and update statistics are updated for the local copy. The last-accessed time is reset and the last-modified time is updated to the time in the remote cache, with corrections made for system clock differences. Thus the local entry is assigned the true last time the entry was modified in the distributed system. The netSearch
operation has no effect on the expiration counters in remote caches.
The netSearch
method operates only on distributed regions with a data-policy of empty, normal and preloaded.

Explainer: Your rights in a PSV
by CLAIRE WASILWAIn Summary
- With the expected rush for PSV transport during the festive season comes the ugly side of high demand —inflated fares, double bookings, reckless driving, overloading, delays and outright bad manners by drivers and conductors.
The festive season is here and many Kenyans are expected to travel upcountry to celebrate with family and friends.
Others will make trips to holiday destinations to enjoy good times and make memories.
A good majority of these travellers will use public means in the form of buses, matatus and tuk tuks.
With the expected rush for PSV transport during the festive season comes the ugly side of high demand — inflated fares, double bookings, recklessly-driven vehicles, overloading, delays and outright bad manners by drivers and conductors.
But, as a PSV passenger, do you know that you have rights? Do you know there are laws and policies that protect you from exploitation and inhumane treatment during PSV travel?
Here are some:
FARE
The Traffic Act requires drivers and conductors to behave in a civil, honest and orderly manner.
The law says the vehicle administrators shall not wilfully deceive or refuse to inform passengers of the correct fare for any journey. If overcharged, passengers have rights to demand an explanation.
PSV users should make use of hotlines provided in case of an accident, report acts of careless driving, excess passengers and theft among other incidents.
In March, the National Transport Safety Authority (NTSA) wanted to introduce amendments that would enable them to regulate fare tariffs but the proposal was shot down by vehicle owners.
So, in the meantime, the various saccos will still inflate fares depending on demand.
REFUNDS
If the vehicle is delayed by more than four hours, owing to a breakdown or any fault or neglect by the owner or his servants or agents, any passenger who has paid fare may elect to alight and recover a proportion of the fare in respect of the uncompleted journey.
It shall be the duty of the person who received the fare to repay it to the passenger on demand.
The Traffic Act provides that ''any person failing to repay a fare shall be guilty of an offence and liable to a fine not exceeding Sh10,000 in addition to being ordered to repay the fare, and the amount of the fare shall be recoverable as a fine.''
DEATH AND INJURY
In case you are involved in an accident as a passenger, you should file a third party claim with the driver's auto insurance provider.
Most insurance firms cover third party bodily injury and property damage arising out of an accident.
LUGGAGE
Every public sacco has its own rules that govern all drivers and passengers.
In most long-distance journeys, in case you alight and forget your luggage in the vehicle, you can claim your bags at the booking office.
Most saccos deny responsibility for lost luggage but, if you have a receipt, that indicates it was received by the bus or shuttle company, you can lodge a court case.
COMFORT
For those travelling over long distances, passengers are entitled to choose their preferred seat which is comfortable.
The driver is also supposed to stop over at a motel to allow passengers to eat and use rest rooms before proceeding.
CHILDREN
According to the Traffic Act, a child who is under the age of five years and who does not occupy a seat shall not count as a person.
The driver or conductor does not have to force you to pay for an extra seat for a child under five years if you don’t want to.
You are also allowed to pay for one seat to be occupied by your two children as the Traffic Act provides that ''any two children each of whom is over the apparent age of five years and under the apparent age of 12 years shall count as one passenger.''
ACCESSIBILITY
Every person should be able to easily access a door or window.
The Act states that no seat, luggage, parcel or other object shall be placed in a motor omnibus so as to obstruct persons attempting to reach any door, emergency window or panel.
RULES
However, as a public service vehicle passenger, you have to adhere to the rules provided by matatu saccos for your own safety.
Saccos do not allow alcohol, drugs, weapons, pets, gas cylinders on board and require that a passenger be inspected before boarding the vehicle.
Fasten your seat belt and alight at an authorised bus stop to avoid paying a Sh1,000 fine.
