Understanding the SecurityManager in Apache Shiro
The SecurityManager lies at the heart of Shiro's architecture. While the Subject represents security functionality and state for a single application user, the SecurityManager performs security operations and manages state for all application users.
Because Shiro's API encourages a Subject-centric programming approach, most application developers will rarely, if ever, interact with the SecurityManager directly (framework developers however might sometimes find it useful). Even so, it is still important to know how the SecurityManager functions, especially when configuring one for an application.
Design
As stated previously, the application's SecurityManager performs security operations and manages state for all application users. In Shiro's default SecurityManager implementations, this includes:
- Authentication
- Authorization
- Session Management
- Cache Management
- Realm coordination
- Event propagation
- "Remember Me" Services
- Subject creation
- Logout
and more.
But this is a lot of functionality to try to manage in a single component. And, making these things flexible and customizable would be very difficult if everything were lumped into a single implementation class.
To simplify configuration and enable flexible configuration/pluggability, Shiro's implementations are all highly modular in design - so modular in fact, that the SecurityManager implementation (and its class-hierarchy) does not do much at all. Instead, the SecurityManager implementations mostly act as a lightweight 'container' component, delegating almost all behavior to nested/wrapped components.
Modularity
To simplify the SecurityManager implementation complexity and allow for pluggable behavior, the Shiro SecurityManager implementations delegate almost all logic to a nested set of modular components that actually perform the necessary functionality. While the components actually execute the logic, the SecurityManager implementation knows how and when to coordinate the components for the correct behavior.
The nested components that the SecurityManager coordinates and delegates to are:
- Authenticator (org.apache.shiro.authc.Authenticator)
- Authorizer (org.apache.shiro.authz.Authorizer)
- SessionManager (org.apache.shiro.session.mgt.SessionManager)
- CacheManager (org.apache.shiro.cache.CacheManager)
- RememberMeManager (org.apache.shiro.mgt.RememberMeManager)
- SubjectFactory(org.apache.shiro.mgt.SubjectFactory)
The SecurityManager implementations and are also JavaBeans compatible, which allows you (or a configuration mechanism) to easily customize the pluggable components via standard JavaBeans accessor/mutator methods (get*/set*). This means the Shiro's architectural modularity can translate into very easy configuration for custom behavior.
| Easy Configuration Because of JavaBeans compatibility, it is very easy to configure the SecurityManager with custom components via any mechanism that supports JavaBeans-style configuration, such as Spring, Guice, JBoss, etc. |
Programmatic Configuration
The absolute simplest way to create a SecurityManager and make it available to the application is to create a org.apache.shiro.mgt.DefaultSecurityManager and wire it up in code:
Realm realm = //instantiate or acquire a Realm instance. We'll discuss Realms later. SecurityManager securityManager = new DefaultSecurityManager(realm); //Make the SecurityManager instance available to the entire application: SecurityUtils.setSecurityManager(securityManager);
Surprisingly, after only 3 lines of code, you now have a fully functional Shiro environment suitable for most applications. How easy was that!?
You could additionally call any of the SecurityManager instance's setter methods with custom implementations of the nested components listed above to fully customize its behavior.
But, as simple as programmatic customization is, these 3 lines of code do not represent the ideal configuration for most real world applications. There are a few reasons why programmatic configuration may not be suitable for your application:
- It requires you to know about and instantiate a direct implementation. It would be nicer if you didn't have to know about concrete implementations and where to find them.
- The SecurityUtils.setSecurityManager method call makes the instantiated SecurityManager instance a VM static singleton, which, while fine for many applications, would cause problems if more than one Shiro-enabled application was running on the same JVM. It could be better if the instance was an application singleton, but not a static memory reference.
- It requires you to recompile your application every time you want to make a Shiro configuration change.
Most applications instead benefit from text-based configuration that could be modified independently of source code and even make things easier to understand for those not intimately familiar with Shiro's APIs.
Text Configuration
Shiro provides a simple INI-based configuration that can be used out of the box, but any other JavaBeans-compatible mechanism can be used as well. For example, Shiro has excellent Spring support too. Other similar frameworks (Guice, JBoss, etc) could also be used.

Apprentice Is the Premier Case Competition for Waterloo's Most Innovative Students
Find Out MoreU.W Apprentice is a unique entrepreneurial competition where case studies are created with local start-up companies based on real-life problems that they and their industry face. This is the only competition where delegates are able to present their solutions to the actual CEO and officials from the companies. Delegates will have the opportunity to meet other passionate and driven students like themselves. The best students from across the region and province will compete against one another for the title of “The Apprentice”.
Selection of these students are through 2 rigorous rounds—application forms and pre-competition screening. Students participate in back-to-back case studies from start-ups and other companies connected to Waterloo’s entrepreneurship network. U.W Apprentice benefits students, sponsors, our partner school clubs, start-up companies and the universities involved via exposure, network building, marketing, and publicity.
The Waterloo Region has long been dubbed Canada’s innovation hub, and is home to a large start-up community, including organizations like the Communitech Hub, U.W Velocity, and Laurier LaunchPad. Students from the University of Waterloo and Wilfrid Laurier University are world renowned for their high calibre and broad co-op experiences and there is high interest in entrepreneurship within students from all faculties. We aim to inspire, enrich, and educate our delegates with hands-on case experience based on real life problems that start-ups face in this upcoming Regional Competition.
The most recent competition will take place on March 11 – 13, 2016 at the University of Waterloo campus, where four exciting start-ups from the Waterloo community will present a problem to our cohort of 20 delegates & receive creative solutions to create growth, value and tangible impact. The start-ups and their cases provide a diverse picture of the start-up world. This weekend is your chance to show yourself and the world that you have the grit, intelligence, eloquence, and tools to become Waterloo’s next great entrepreneur.
In the previous year, we opened the competition to the talented entrepreneurial-minded students at other universities beyond the Kitchener-Waterloo region. This included Queen’s University, Western University, University of Toronto, and Schulich School of Business, among many others. Our executive team is dedicated to growing the competition and promoting U.W Apprentice to the student body across the region and province this year. We are looking to make mutually beneficial partnerships with other school clubs in the near future to support our rapid expansion.

After Historic Swimming Gold, Simone Manuel Addresses Police Brutality And Racism
By Lindsay Gibbs for thinkprogress.org on August 12, 2016
On a day in which Michael Phelps won his 22nd gold medal and Simone Biles cemented her legacy as the best gymnast ever by winning the all-around gold by a record margin, it was another American, Simone Manuel, who broke down the most significant barrier.
On Thursday night in Rio, Manuel became the first African American woman to ever win an individual swimming medal at the Olympics. It happened to be a gold. In the 100-meter freestyle, Manuel actually tied for first place with 16-year-old Canadian Penny Oleksiak, clocking in at 52:70, a new Olympic record.
The significance of the moment was not lost on her, particularly considering the racial tensions back home.
“It means a lot, especially with what is going on in the world today, some of the issues of police brutality,” Manuel said after the race, as reported by USA Today. “This win hopefully brings hope and change to some of the issues that are going on. My color just comes with the territory.”
Her post-race interview was one of the most emotional ones of the entire Olympics.
“I just want to be an inspiration to others that you can do it,” Manuel said through tears.
According to USA Swimming, 70 percent of black people can’t swim at all, and as a result, African American children drown at a rate three times higher than their white peers.
This is because public pools in the United States historically went through extremes to keep black people away. Pools were not built in black neighborhoods, and, as Fusion notes, public pools would often turn private just to avoid integration during the civil rights movement.
 Unfortunately, those notions aren’t completely extinct. In 2013, when Italian Gymnastics Federation official David Ciaralli tried to defend racist comments by Italian gymnast Carlotta Ferlito directed towards Simone Biles, he instead expanded the bigotry to swimming.
“Why are there no black swimmers?
Just last year in Texas, the state that Manuel is from, a cop was suspended after brutally snatching a black teenager by the hair, wrestling her to the ground and sitting on her, outside of a neighborhood pool.
So, there is understandably a lot of attention paid to African American swimmers in the spotlight, and it’s something that the 20-year-old Manuel, who is competing in her first Olympics, has had to deal with throughout her career.
“It is something I’ve definitely struggled with a lot,” Manuel told reporters after winning gold. “Coming into the race I tried to take weight of the black community off my shoulders. It’s something I carry with me. I want to be an inspiration, but I would like there to be a day when it is not ‘Simone the black swimmer.’
Manuel and her teammate Lia Neal had already made history before Rio started — this was the first time that two black women had made the USA Olympic swim team simultaneously. But they are far from the only African American woman to make history in Rio. In gymnastics, Biles and Gabby Douglas are a part of the first majority minority American gymnastics team in Olympic history, along with Latina Laurie Hernandez. In tennis, all four female singles players were African American for the first time ever — Serena Williams, Venus Williams, Sloane Stephens, and Madison Keys.
Fencer Ibtihaj Muhammad, the first American to compete in the Olympics with a hijab, is also African American, and Ashleigh Johnson is the first black woman to compete on the U.S. Olympic water polo team.
There’s still time for Manuel to make more history, as she still is going to compete in the 50-meter freestyle.
But with her swim on Thursday night, Manuel has already done her part to change the face of the sport forever. Afterwards, she gave credit to the African American swimming pioneers who came before her, such as Maritza Correia and Cullen Jones.
“This medal is not just for me. It is for some of the African-Americans who have come before me,” she said. “This medal is for the people who come behind me and get into the sport and hopefully find love and drive to get to this point.

So finally it happens, i have a blog page now, like millions of those people all round the world, who type their way to glory. Am really not sure why people blog, and i really dont care much at the moment, since am a part of this blogging 'fraternity'.
I owe it to & for they are the guys who actually got me into this. (Am sorry if i my tone does not sound thankful!).
I welcome myself to the vast world of Weblog!
Cheerio.
P.S: This thing might not look good. Am still finding my way thru this thing. Should look good soon, if i dont give up that is.

Chapter 15 Epilogue
The story ends abruptly. I asked my family what happened when he was ‘liberated’ by the soviet army? Did he go back to his home-village Brzeznica?
He did not go back immediately. This story was published during Polish communism so Stasiek needed to be careful what he wrote.
Many Polish soldiers that fought on the side of the allied forces and returned to Poland were tortured and/or murdered by the Russians. Many such stories were told to me when I lived in Poland during the 80s.
As my uncle also returned from ‘the west’, he had to go in hiding, again, until his story would be verified by different sources.

Salutations! My name is Kyle Richmond and I am originally from Fort Wayne, IN. I have lived in Seattle for a little over 4 years now. I am a hobbiest gamer. I enjoy table top RPGs (role playing games using paper, pencil, and dice.), LARPs (Live action role playing) where you dress up in costumes, use foam weapons, Nerf guns, and interact with other players while working together creating a story.
I have very little coding experience in my past other than some very basic HTML from Angelfire and Geocities chat rooms. I am excited to be learning coding and looking forward to seeing where my coding path takes me.
One of my goals is to be able to create a website, for one of the LARPs I created, that will allow a player to Created and manage that character, have an in game store, bank, and functioning "hacking game".

Ethereum Price Weekly Forecast: ETH Holding Uptrend Support
- ETH price declined recently below the $188 and $186 support levels against the US Dollar.
- The price is still trading above the key $180 and $178 support levels.
- There is a crucial bullish trend line forming with support near $180 on the 4-hours chart of ETH/USD (data feed via Kraken).
- The pair could start a fresh increase as long as there is no daily close below the $178 support.
Ethereum price is currently holding a significant support against the US Dollar, while bitcoin is declining. ETH price is likely to rise towards $188 and $190.
Ethereum Price Weekly Analysis
This past week, Ethereum started a slow and steady decline from well above $190 against the US Dollar. More importantly, ETH traded below the key $188 support to move into a short term bearish zone.
Moreover, there was a break below the key $186 support area. Finally, the price spiked below the $182 support and the 100 simple moving average (4-hours). However, the bears failed to gain strength below $180.
As a result, Ethereum recovered above $182 and 100 simple moving average (4-hours). Besides, it traded above the 23.6% Fib retracement level of the downward move from the $194 swing high to $180 low.
The price even climbed above a connecting bearish trend line with resistance near $184 on the 4-hours chart of ETH/USD. At the moment, the price is consolidating above the $182 level and the 100 SMA.
An immediate resistance is near the $188 area (the previous support). Additionally, the 50% Fib retracement level of the downward move from the $194 swing high to $180 low is also near the $188 level.
Therefore, an upside break above the $188 resistance could push the price further higher. The next key resistance is near the $194 area. Any further upsides may perhaps set the pace for a break above the $200 barrier.
On the downside, there are many key supports near the $180 and $178 levels. Furthermore, there is a crucial bullish trend line forming with support near $180 on the same chart. Only a daily close below the $178 support could start another downward move towards the $160 level.
The above chart indicates that Ethereum price is clearly holding a couple of important uptrend supports near the $178 level. Thus, there are chances of a fresh increase above the $185 and $188 levels unless there is a clear break below $178.
Technical Indicators
4 hours MACD – The MACD for ETH/USD is about to move into the bullish zone.
4 hours RSI – The RSI for ETH/USD is currently below the 50 level, with a few bullish signs.
Major Support Level – $178
Major Resistance Level – $188

--- layout: default title: "Indian fusion" identifier: "indian-fusion" excerpt_separator: ---
I went shopping in India a while back, and noticed a drastic difference in the stores’ selections. Where I had once been shown lehenga after lehenga, I was now being pushed toward full-length gowns with traditionally embellished bodices. My online search revealed the same new category: “Indian fusion”, otherwise known as “Indowestern”.
Although Indian fusion started as just gowns (so, anarkalis without pants), it’s quickly grown to include modern silhouettes such as culottes, capes, and jumpsuits. Designers seem to be taking full advantage of this trend, some departing from traditional garb altogether. One of my favorites, Ridhi Mehra, does an especially good job of blending Indian and Western sensibilities in her latest two collections, Adorne and Mirabella:
What strikes me the most about these looks, aside from their obvious glamour, is how each one perfectly tows the line between sexy and modest. In Indian culture, women are expected to dress conservatively, and you’d be pressed to find an outfit that shows some leg. But, thanks to the long-standing tradition of wearing saris, there’s a little more leniency from the midriff up. If you look again, you'll notice that the last three outfits take full advantage of this, without overdoing it.
With Indian fusion, it’s much easier to gauge what’s appropriate for your particular occasion. For black-tie events, I’d stick to gowns, but otherwise I'd freely substitute styles. If you're ever unsure, simply consider the Western equivalent and whether you would feel comfortable wearing it!

4-FA aka 4-FMP aka 4-FluoroAmphetamine.
I took 120mg of the fumarate on an empty stomach. It took an hour to kick in.
Physically it felt like a cross between being stoned and having the flu. Sometimes some chills showing up. There was also some moderate hyperthermia as often with amphetamines. Moderate heart beat acceleration. Mentally, there was a kind of matter of fact calmness, an emotionnal smooth bluntness so to speak, a tinge of cannabis-like stoning and some psychedelic-like emotional sensitivity. There was no mood lift in sight and in fact a mood that was slightly grim/sad and neutral at the same time. Pupils were dilated. After 6h i could still feel it but it was very weak and subtle, almost residual. It was never unpleasant nor threatening, but it wasn't pleasant either. It just was. There was also a faint anorexia but i ate a pizza nonetheless (i was having dinner in a restaurant with friends). Dry mouth for sure. Mini me was out to lunch. I went to sleep at about T+7h without much problem.
The next day (ie now at T+21h ) i had chills and even goose-bumps from time to time which have eventually subdued. I also have some aches coming and going on my ears, fingers and temples and my kidneys don't feel in their best of shapes. There is still a persistent anorexia (still haven't eaten) and i feel a touch of nausea could show up if i were presented food. A slight mental spaciness and i really still feel as if i have the begining of a flu. My head feels weird, almost absent. I'm not in my best of moods either, kinda down and a bit fragile physically and mentally.
All in all it's not a pretty picture. It was boring, nothing interesting at all, just a waste of time. Smoking a joint of good cannabis or taking codeine instead would have been mentally stronger and more interesting ! Now i feel sick.
I wasn't expecting this at all from what i had read. I was expecting better than that in fact, something between amphetamine and MDMA. It was light years away from either. I don't know if it's because my stuff could've degraded in solution or because i underdosed, but this is basically not something that i'm going to repeat EVER. I just flushed the rest of my vial.
Restrospectively, it seems to me like this is a toxic compound.
I would advise to steer clear of it.

Photography in Bergen
I love photography. And I am lucky enough to live in a country and city that makes it easy.
Bergen Almost feels like cheating at times.
Northern Lights This winter I went out looking at a meteor shower. I did not get any good photos of the shower itself, but I was able to capture the northern lights. Worth being tired the next day at work!

THE BABYSITTER (1995) A Film Review by Ted Prigge Copyright 1997 Ted Prigge
Director: Guy Ferland Writer: Guy Ferland (based on a story by Robert Coover) Starring: Alicia Silverstone, Jeremy London, Nicky Katt, J.T. Walsh, Lee Garlington, George Segal
Everybody in this film's thinking of Alicia. No, this is not a documentary on those of us after we first saw the "Cryin'" video. This is one of those erotic thrillers, but not like one starring Shannon Whirry or Shannon Tweed. First off, there's zero sex, almost no nudity, and it's not as well-plotted as one of those Tweed flicks.
Well, anyway. The "plot." Alicia plays, well, the babysitter, who is taking care of some kids one night while the parents (J.T. Walsh and Lee Garlington) go out to a party. The film, trying to be like one of those introspective erotic thrillers, shows every characters' thoughts, except Alicia's. The thing is Alicia's in most of them in most cases, and the thoughts aren't too kosher.
First off, there's her boyfriend (Jeremy London, who gave one of the all-time lousy performances in "Mallrats," and is only a notch better here), who's a dorky kid who hangs out with a kind of bully, played by Nicky Katt from "subUrbia" (who shows he's got that quiet creepiness down pat once again). They decide they want to crash her babysitting job, looking for the typical babysitting hanky-panky. Somethine like that.
The film intercuts between the subplots (Alicia babysitting, Nicky and Jeremy, the party) and each characters' thoughts. We get to see Jeremy and Nicky's dreams of doing a little threeway with Alicia, J.T. thinking of coming home to find Alicia naked in the bathtub (she has it all covered up, the little tease), and, worst of all, Lee Garlington dreaming of that hunk, George Segal. It even shows them in bed together. Yea. I SO wanted to see George and Lee Garlington in bed, though I guess I'm used to George after seeing her and Mary Tyler Moore fooling around in "Flirting With Disaster."
The ending is some kind of big tragedy thing, but come on. Like we care about any of the characters. The only interesting one is Alicia, mainly because she's Alicia, and we mostly see her in the fantasies. So I guess she's some kind of mystery or something. But she is never explored further. So, basically, this film is just a series of mastabatory images, sometimes featuring a non-nude Alicia (once again, sadly), sometimes featuring a scantily-clad George Segal (once again, sadly).
I watched this on one of those free previews of Showtime or Cinemax one night, and let me tell you, it is the only way to watch this film. I mean, there's a reason they put these kinds of films on late at night: they're just as good as sleeping pills.

C Programming Language¶
Learning C¶
The best way to learn programming is, always, writing your own code!
Why Code in C Anymore?….Instead of C++
C still has a little advantage on the performance and portability.
CS2022: Introduction to C at Cornell
Lecture slides are available.
-
Curated collection of useful C Programming tutorials, snippets, and projects that you can understand in 30 seconds or less
Useful Libraries¶
Performance¶
Optimization of Computer Programs in C
By Michael Lee. “It focuses on minimizing time spent by the CPU and gives sample source code transformations that often yield improvements. Memory and I/O speed improvements are also discussed.”
Tips for Optimizing C/C++ Code
Very practical and useful guides for optimizing C/C++.
mimalloc - mimalloc is a compact general purpose allocator with excellent performance
By Microsoft. mimalloc (pronounced “me-malloc”) is a general purpose allocator with excellent performance characteristics. It is a drop-in replacement for malloc and can be used in other programs without code changes.
Numerical¶
-
The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite.
-
FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).
Code to Study¶
sextractor - Extract catalogs of sources from astronomical images
CCL - DESC Core Cosmology Library
Also teaches you how to interact with Python.
Corrfunc - fast correlation functions on the CPU
utils are written in C; and wrapped in Python.
On Interacting with Python¶

THIS IS WHERE I CAN ATTACH MY RESUME!!
HERE'S MY NUMBER. CALL ME!


Hi, I'm Chakrya (pronounced Chalk-re-ya.)! I am in the Web Design program, which I plan on completing Summer Quarter. After the program, my goal is to build my portfolio and find employement in the UX industry. I'm hoping knowing how to code will give me a competitive edge over other applicants.
I grew up on the Eastside but now reside in Seattle. I have twin boys who have ruled my world for the last 3.5 years. Prior to having kids, I snowshoed, hiked, tried out new restaurants with friends, and traveled domestically and internationally.


The main idea is to create three paths that describe the trajectory of each bar in the menu icon when it transforms into the cross.

- The application requests authorization to access service resources from the user. The application needs to provide the client ID, client secret, redirect URI and the required scopes.
- If the user authorizes the request, the application receives an authorization grant
- The application requests an access token from the authorization server by presenting authentication of its own identity, and the authorization grant
- If the application identity is authenticated and the authorization grant is valid, the authorization server issues the access and refresh (if required) token to the application. Authorization is complete.
- The application requests the resource from the resource server and presents the access token for authentication
- If the access token is valid, the resource server serves the resource to the application
The are some main Pros and Cons in OAuth 2.0
- OAuth 2.0 is easier to use and implement (compared to OAuth 1.0)
- Wide spread and continuing growing
- Short lived Tokens
- Encapsulated Tokens
— No signature (relies solely on SSL/TLS ), Bearer Tokens
— No built-in security
— Can be dangerous if used from not experienced people
— Too many compromises. Working group did not make clear decisions
— Mobile integration (web views)
— Oauth 2.0 spec is not a protocol, it is rather a framework — RFC 6749

Smriti Irani Pokes Fun At Herself And Bill Gates For Being College Dropouts; Ekta Kapoor Has A ‘Kyunki’ Twist
by Divya RamnaniLOL! Tulsi Irani makes fun of hers and Bill Gates’ for being college dropouts, here’s how Ekta Kapoor reacted
Hands down, Smriti Irani is the coolest Instagrammer in recent times! Why do we say so? Well, it’s the actor-turned-politician’s hilarious, at the same time self-trolling posts that always keep her followers entertained. Irani often shares some witty captions when it comes to her weight and her family. And with her most recent post, Smriti Irani went a notch higher and poked fun at the fact that she is a college dropout and, umm, this time, she didn’t spare Bill Gates either. (ALSO READ - Smriti Irani’s Meme Game Is On Point As She Shares The Most Relatable And Hilarious Weekend Meme)
Taking to her Instagram account, the BJP politician shared a picture of her with the billionaire Bill Gates, who was on a trip to India recently. The picture sees Bill Gates and Smriti Irani engrossed in a conversation. Well, Smriti being Smriti, gave this picture a hilarious twist through her caption. She wrote how since the two of couldn’t complete their studies and are dropouts, they are wondering what to do in the future. “सोच रहे हैं पढ़ाई पूरी करी नहीं , आगे क्या करे” (We are thinking since we didn't complete our studies, what should we do in future?). LOL! While Smriti Irani is a college degree dropout, Bill Gates, the co-founder of Microsoft, is a dropout from Harvard.
Check out the picture below:
Soon after, Smriti Irani’s good friend and TV czarina Ekta Kapoor was quick to pour in her reaction on this picture by giving it a Kyuki (a popular show of hers that starred Smriti Irani in the lead role) reference. She gave it her caption by commenting, "Bosss ! Tulsi kyunki abh bhi yaaad hai......pls waaapsi Karein.” We wish the same, Ekta!
Take a look:
We wonder how Bill Gates would react to this joke though!

This is a step-by-step guide, describing the needed steps to reuse a library built with the Xcode Maven Plugin
The used library is already deployed in an available Maven Repository.
Your project specifies a dependency to the dependent library to use in the dependencies section of the pom.xml.
<dependency> <groupId>com.sap.tip.production.prototype.xcodeprojects</groupId> <artifactId>MyLib</artifactId> <version>1.0.0-SNAPSHOT</version> <type>xcode-lib</type> </dependency>
Additionally you have to link the library in your XCode project as usual:
Objective-C does not define linker symbols for each function (or method, in Objective-C) - instead, linker symbols are only generated for each class. If you extend a pre existing class with categories, the linker does not know to associate the object code of the core class implementation and the category implementation. This prevents objects created in the resulting application from responding to a selector that is defined in the category. Detailed information can be found here: https://developer.apple.com/library/mac/#qa/qa1490/_index.html
To resolve this issue, the target linking against the static library must pass the -ObjC option to the linker. This flag causes the linker to load every object file in the library that defines an Objective-C class or category.

How to change the date format in Microsoft Excel to make the program write dates in a certain way
by Laura McCamy- You can change the way that dates are formatted in an Excel spreadsheet with just a few clicks.
- Excel is good at automatically recognising when you enter a date, and formatting things to the date format of your choosing.
- Excel offers a wide variety of format choices for displaying dates.
- Visit Business Insider’s homepage for more stories.
When you enter a date that’s formatted with slashes, Excel will recognise it as a date. For example, Excel will automatically choose the date format for a cell that contains 11/11/19.
You can set Excel to display dates in a variety of ways, no matter how you type in the data.
Here’s how to find and change date formats in Excel on a Mac or PC.
Check out the products mentioned in this article:
Microsoft Office (From $US149.99 at Best Buy)
MacBook Pro (From $US1,299.99 at Best Buy)
Lenovo IdeaPad (From $US299.99 at Best Buy)
How to change the date format in Microsoft Excel
We’re using a spreadsheet that includes dates of hire for employees of a fictitious company, to show different ways to format dates in Excel.
1. Highlight the date cells you want to format.
2. In the “Home” menu ribbon, there is a field in the middle with a drop-down menu for different cell formats. It should say “Date” by default. Click the arrow to open the drop-down menu.
3. The menu has two formats for dates: short date and long date.
- Short date displays months and days as either single or double digits and years as double digits. For example, January 1, 2019 would be displayed as 1/1/19.
- The long date option adds the day of the week and writes out the month. So 1/1/19 will display as Tuesday, January 1, 2019. The date will display in the format you choose, no matter how you enter it. If you type “1/1/19” into a cell with the long date format, Excel will change it to the expanded date.
4. Excel offers many other date format choices. In the cell format menu, click on “More Number Formats…” at the bottom.
5. In the window that pops up, make sure “Date” is chosen under the “Category” sidebar. You can scroll down the list of date formats in the box to the right. Choose from formats that put the day before the month, drop the year, and more. We chose the last option and the data, which was entered with two-digit years, was converted to display four-digit years.
Pro tip: Never change the format of a cell with a date to General or Text. Excel will turn your date into an unrelated number. For example, 3/3/2017 becomes 42797 when it’s not formatted as a date.

A performance metrics dashboard for continuous context recognition systems
We've been investigating systems for automated recognition of places, visits, paths, and activities from mobile sensor data, and have developed these tools to help evaluate the feasibility and quality of various approaches. This project provides a framework for: 1) defining ground truth data from labeled streams of sensor data, 2) interfacing with context recognizer(s), and 3) scoring and visualizing recognizer performance based on [1].
This section describes a simplified development lifecycle for continuous context recognition systems and explains how this framework fits in. For our purposes, continuous context recognition systems infer/predict the context of a user and/or device, from periodic samples of raw sensor data. A context recognizer outputs/updates labeled time intervals that encode the prediction/esitimation of the context over the time interval, for example: HOME, WORK, RUNNING, WALKING, BIKING, DRIVING.
Ground truth collection - To help drive the development, we start with the collection of ground truth corpora consisting of raw data files (typically collected from sensors carried or worn by a subject) and ground truth labels provided by researchers, subjects, click workers, or other observers, over intervals of the data. The labels provide the truth about what the user (or device) was doing during the labeled interval, and are essential for the development and evaluation of systems for classification, detection, or recognition.
Recognizer development - Now that we have some raw data and ground truth, we begin developing our recognition system. Here, we mainly focus on binary classification, and try to build and test various recognizers that can infer the context of the user from some raw data streams. We implement the abstract recognizer interface that allows user-defined classifiers to be plugged in to the test framework.
Evaluation - Once we have candidate recognizers ready for testing, we feed raw data from ground truth cases to specified recognizers (implementing the recognizer interface) and analyze the returned results. The recognizer results are compared with the ground truth labels, detailed performance metrics are computed, test results are logged, and visualizations are rendered for inspection.
Iteration - Based on the performance results, we may return to step 2 and tweak parameters, modify code, try something new, etc. Alternatively, we can return to step 1 to gather more labeled data and refine or scale up the testing. Once we are satisfied with the results over a diverse set of test cases, we begin to productize.
The command line interface and scoring rules are implemented in python 2.7. The visualizations are made with javascript, jQuery, and d3.js. iso8601.py is used for date parsing in python
Raw data files contain timestamped sensor and/or behavioral data logged (continuously or periodically) from one or more devices associated with a test subject. We often use mobile phone sensors like WLAN, GSM, GPS, magnetometer, Bluetooth, ambient light, microphone, etc, but may also include data from other sensors in the environment or worn on the body, or from external data sources. Raw data records are encoded in an application specific manner and thus should only be passed to recognizers that understand the format.
Ground truth files encode labels containing the precise start and end times of specific activities performed by the user during the raw data collection. The ground truth label files are encoded in json and have the following form:
The following table describes the various fields of ground truth items:
data_path
- glob expression specifying raw data files for this casedescription
- description of test case (optional)sw
- client software identifiert1
- earliest t1 of data record, label, or detectedt2
- latest t2 for data record, label, or detectedhw
- device hardware identifierdevice
- device model (optional)subject
- information about the human subject (optional)labels
- list of labeled intervals over the raw data. Each item in the list contains:
t1
- isotime timestamp of label startt2
- isotime timestamp of label endlabel
- A string constant that labels the context. See list of pre-defined labelsbody_position
- String constant identifying the where the device was carried on the body (optional)data
- label-specific data (optional)How ground truth labels are initially captured is out of the scope of this document, but there are various approaches such as verbal self-reporting, user diaries, mobile phone-based labeling tools, crowdsourced labeling, and following subjects around with clipboards.
Here are some predefined labels for various context items:
AT_HOME
AT_WORK
IN_PLACE
- Visiting a specific place. The data
portion of IN_PLACE
labels are dictionaries that may contain the following optional fields:
id
- The place id name
- The place name address
- The place address ll
- Approximate ll of the visit desc
- A description of the place ENTERING_PLACE
EXITING_PLACE
WALKING
RUNNING
BIKING
SKATEBOARDING
SNOWBOARDING
SITTING
STANDING
SLEEPING
DRIVING
IN_CAR
ON_TRAIN
ON_BUS
ON_BOAT
ON_PLANE
Recognizers process time-ordered chunks of raw data records and return lists of recognizer results. Recognizers MUST implement the recog.AbstractRecognizer
interface to be compatible with this framework. The recog.AbstractRecognizer
python class is shown here:
Raw data are fed to a recognizer using the process()
method. Results are retrieved using the get_results()
method and example is shown in recognizer results. The labels_supported()
method is used to filter the ground truth labels to include only those supported by the specified recognizer before the results are compared.
The get_results()
method returns lists of dictionaries containing the labeled time intervals. For example, recognizer results have the following form (after json-encoding):
A test run typically contains the following steps:
The perfboard
command line utility is used to run performance tests.
perfboard.py [-h] [--outpath OUTPUT_PATH] [--norotate] --recognizers RECOGNIZERS TRUTH_FILE [TRUTH_FILE ...]
For example, to test the test.recognizers.DummyWalkingDetector
against the example_truth.json
test case:
./perfboard.py --recognizers=test.recognizers.DummyWalkingDetector test/example_truth.json
By default, result objects are written to static/scores.json
and can then be retrieved by the performance dashboard via ajax.
Existing scores file are copied to timestamped filenames before new results are written and a list of scores history is updated in the static/scores_list.json
file. The dashboard reads the scores list and presents it in a pulldown menu. To disable the rotation of scores to timestamped files use the --norotate
option.
To run the example tests conveniently, use:
test/test.sh
Final test results are encoded in a object that combines all ground truth items, results from recognizer get_results()
, and all performance metrics. For example, test results from the above example might look like the following:
The result object has the following fields:
t
: timestamp of the test run in isotimestats
: dictionary of total number of ground truths truth_count
, recognizer results detected_count
, and scored segments segment_count
from all test casesresults
: list of the scored test case results. Each result object has the same form as a ground truth item, with additional keys:
detected
: list of recognizer results for the testscores
: dictionary containing event scores, frame scores, and various stats for the testrecognizer
: field specifying which recognizer was used in the testevent_score
: field containing the event score for items in labels
and detected
recognizers
: list of recognizers that were used in the testscores
: dictionary of aggregate scores from all ground truth cases combined. The dashboard can be accessed by running a web server and serving the perfboard/static
dir and visiting the index.html
file there.
Note: The dashboard won't work when served using file://
url rather than http://
url (for ajax security reasons).
The top of the dashboard shows an overview of results from all the test cases in a test run:
The overview shows the test time, total number of ground truth cases, total number of ground truth labels, total number of items detected, and the overall stats for frame and event scores. Frame scores report the fraction of time that the detection output matches the ground truth. Positive frames are those where we have a ground truth prediction for the frame, negative frames are those where there is no ground truth label (null-class). Overview statistics and pie charts for positive frames, negative frames, ground truth events, and detected events show the rates of the various kinds of errors.
The top bar also provides a pull-down selector to jump to individual test results, and another pull-down selector for rendering other result sets.
Each ground truth case in a result set is rendered in a result detail panel similar to that shown here:
The result detail shows similar statistics and pie charts for positive frames, negative frames, ground truth events, and detected events, but also includes a time interval diagram and event analysis diagram. The time-interval diagram shows the truth, detection, and segment time intervals and corresponding scores. Hovering over the intervals will show the timing, labels, and scores. The event analysis diagrams shows the truth and detected event scores in a single chart.
The metrics used in test results are based on [1]. This section briefly describes some of the metrics.
Event scores are assigned to ground truth labels and also to recognizer results. This table provides summary of score types described in [1]:
D
- DeletionF
- FragmentedM
- MergedFM
- Fragmented and mergedC
- CorrectI
- InsertionF'
- Fragmenting returnM'
- Merging returnFM'
- Fragmenting and merging returnScores are also assigned to segments as described in [1]. Segments are scored with one of the following four types:
TP
- True PositiveTN
- True negativeFP
- False PositiveFN
- False NegativeFor FP
and FN

You will fail.
by Xeni JardinCNN political correspondent Abby Phillip was among the first to share a provocative tidbit of Washington gossip on Twitter today.
Earlier today, Phillip (who is wonderful, you should follow her on Twitter) tweeted that current Trump White House Press Secretary Stephanie Grisham claims that White House aides for outgoing President Barack Obama aides left 'you will fail" notes in offices for incoming Donald Trump aides.
“We came into the White House, I’ll tell you something. Every office was filled with Obama books and we had notes left behind that said ‘you will fail,’ ‘you aren’t going to make it.’”
Former Obama aides say Grisham is lying, and the claim made is almost certainly not true, but let's just dive in anyway.
Baller if true.
If not, it's a good idea.
Seems awfully unlikely is my take.
Nobody, not one, took photographs and posted them on social media?
Come on.
“This is another bald faced lie,” says Ambassador Susan Rice.
There's some news reporting on this now. No evidence. But, nice try.

For the fig-swirl: Melt butter over medium heat in a saucepan. Add brown sugar and stir to dissolve. Halve all of the figs and toss in the saucepan with water and lemon juice. Cook over medium heat, stirring frequently, until you have a chunky-jammy mixture. Add salt with one or two stirs, set aside and let cool completely.
Ice cream: In a small pot over medium heat, combine milk, and granulated sugar until sugar is completely dissolved and the milk is just barely lukewarm. Whisk in egg yolks. Set mixture in the fridge and wait until the fig mixture is cooled.
Using an ice cream machine, pour liquids into the frozen basin and process according to manufacturer instructions, i.e. let spin and thicken for 20 minutes before adding mascarpone, fig jam mixture, and the nuts. Continue to process for +/- 10 minutes. Pour semi-frozen mixture into a pyrex dish or glass tupperware. Freeze for at leaast two hours before serving.
