Press release
£2.5 billion will be invested in apprenticeship training by 2020 under plans unveiled by the government.
The apprenticeship programme - launched in 2010 - has already given 2.9 million people the chance to learn new skills so they can go on to access fulfilling careers and help boost UK business.
The government today (12 August 2016) published proposals for a new funding model for apprenticeships and further details on the apprenticeship levy . The funding will support people of all ages to gain high-quality skills and experience and help employers to offer more training opportunities and build a skilled workforce.
Under the plans for the levy, the government has proposed that employers that are too small to pay the levy - around 98% of employers in England - will have 90% of the costs of training paid for by the government, reassuring millions of small businesses.
Extra support - worth £2,000 per trainee - will also be available for employers and training providers that take on 16- to 18-year-old apprentices or young care leavers. Employers with fewer than 50 employees will also have 100% of training costs paid for by government if they take on these apprentices. This will help to ensure every young person, regardless of background or ability, has the chance to make their first step into work.
Apprenticeships and Skills Minister Robert Halfon said:
We need to make sure people of all ages and backgrounds have a chance to get on in life. Apprenticeships give young people - especially those from disadvantaged backgrounds - a ladder of opportunity. That’s why we continue to work tirelessly to deliver the skills our country needs. The apprenticeship levy is absolutely crucial to this.
Our businesses can only grow and compete on the world stage if they have the right people, with the right skills. The apprenticeship levy will help create millions of opportunities for individuals and employers. This will give our young people the chance they deserve in life and to build a highly-skilled future workforce that the UK needs.
The government is inviting employers and training providers to have their say on the initial funding proposals, to try to ensure final plans fully meet the needs of all those involved in the apprenticeship programme.
The proposals outlined today include plans to:
support all employers to offer high-quality apprenticeships: employers which are too small to contribute to the apprenticeship levy would have 90% of the cost of apprenticeship training paid - ensuring employers of all sizes can develop the next generation of skilled workers
provide extra funding for young apprentices and care leavers: the government will pay an additional £2,000 to help 16- to 18-year-olds, young care leavers and young people with an education, health and care ( EHC ) plan, make their first step into the world of work - with £1,000 going to employers and an additional £1,000 to training providers. Furthermore, employers with fewer than 50 employees will not have to pay anything towards the cost of training a 16- to 18-year-old apprentice, young care leaver or young person with an EHC plan
offer more flexibility for employers to retrain individuals: employers will be able to use levy funds to retrain workers in new skills, even if they have prior qualifications - giving them the freedom to make the training decisions that are right for them so they can train any individual to start an apprenticeship, as long as it is significantly different from their previous qualifications
support employers taking on more apprentices: levy-paying employers - those with a pay bill of over £3 million that want to spend more on training than is in their digital account - will benefit from government support with 90% of their additional apprenticeship training costs being funded, so they can continue to recruit and retrain highly-skilled employees
give employers more control and access to better quality training: employers will have the power to determine exactly what training their apprentices receive and what provider they receive it from. A new register of training providers, also outlined today, will be introduced from April 2017 to improve the link between training providers and employers to will help employers identify a high-quality provider so they can deliver the skills they need to grow.
Petra Wilton, the Chartered Management Institute’s ( CMI ) Director of Strategy, said:
Apprenticeships are a proven route for raising business productivity. Leading employers are already adopting the new professional pathways such as the chartered manager degree apprenticeship, and the new generous levels of government co-investment announced today are welcomed by many businesses, especially those smaller organisations outside the scope of the levy.
I strongly encourage employers to get involved and ensure that this extensive new offer fully meets their needs. As it can provide the much needed injection of confidence and certainty in the skills agenda, which is needed now more than ever.
All employers and training providers now have the chance to feedback on the proposals for apprenticeship funding. You can respond by completing this survey by 5 September. Final funding proposals will be confirmed in October 2016.
The proposal to pay 90% of apprenticeship training costs will apply to the 98% of employers in England that won’t pay the levy when it is introduced in 2017.
By 2019 to 2020 government spending on apprenticeships will be double the level of spending in 2010 to 2011 in cash terms.
In April 2016 the government published a guide for employers on how they will pay the levy , access the digital system and pay for apprenticeships in future. This has been updated with the latest information for employers.
To help employers see how the levy and funding system would work for them, the government has created a new online calculator . The simple to use tool will enable employers to understand how much levy they will pay and how they could use their digital funds to pay for training in future.
For small employers with fewer than 50 employees we propose to waive the co-investment requirement if they take on 16- to 18-year-old apprentices or 19- to 24-year-olds formerly in care or who have an EHC plan. This would mean that these employers will not have to contribute towards the cost of training - the government will pay 100% of the costs.
The proposed apprenticeship funding system will be made up of 15 bands, each with an upper limit ranging from £1,500 to £27,000. The upper limit of each funding band will cap the maximum amount of digital funds an employer who pays the levy can use towards an individual apprenticeship or that the government will co-invest. All existing and new apprenticeship frameworks and standards will be placed within one of these funding bands and it will be up to employers to negotiate prices with providers.

Former HBO CEO Richard Plepler in Talks With Apple About Apple TV+ Production Deal
by Juli CloverFormer HBO CEO and chairman Richard Plepler is in talks with Apple about an exclusive Apple TV+ production deal, reports Deadline.
Plepler is planning to launch a production company and is currently negotiating a deal that would land him with Apple, producing content for Apple's streaming television service.
Image credit: REX/Shutterstock
Plepler, known for his showmanship, creative instincts and willingness to take risks, had been a key driving force behind HBO's success over the past couple of decades. He was elevated to HBO CEO in 2012. Before that he was co-president.
Plepler left HBO in February after spending 30 years at the company and has reportedly spent the last several months exploring different opportunities. According to Deadline, Plepler was not interested in returning to TV as an executive, but was instead looking for opportunities as a producer.
The talks are being conducted by Jamie Erlicht and Zack Van Amburg, two former Sony executives who have been spearheading Apple's television efforts.
Apple has already signed production deals with multiple companies, including A24, Imagine Documentaries, and Oprah Winfrey, plus it has established deals with producers and directors like Jason Katims, Alfonso Cuaron, and Justin Lin.


Apple refreshes MacBook Pro laptop with 16-inch screen
(Reuters) - Apple Inc on Wednesday unveiled a new MacBook Pro with a bigger screen and a better keyboard, replacing its 15-inch model.
The new MacBook Pro will start at $2,399, comparable with the older model, and will be available from Wednesday on its online store and in U.S. retail stores later this week.
The iPhone maker last revamped MacBook Pro in 2016 by adding a fingerprint reader and faster ports. The MacBook line accounts for about 10% of Apple’s total annual revenue of $260 billion.
Apple said the new model will have a “Magic” keyboard that comes with a scissor mechanism delivering 1 millimeter of key travel and a stable key feel.
Apple’s “butterfly” keyboards in older laptops have faced criticism for typing-related problems, including characters repeating unexpectedly, failing to appear, or keys that feel “sticky” and do not respond in a consistent manner.

My very first Engineering Interview
Date: July 17, 2015
Started at 11am finished at 2pm. Hungry / Nervous / Too much Excitment
That was it. I had first a Software Engineer interview! It was... magical. Exactly what I pictured. Whiteboarding whiteboarding whiteboarding. No 'soft' interview, no 'tell me about yourself'. It was pure technical interview with two back-end and two front-end developers.
How did it go? I don't know.
Lessons Learned
If there is one focusing area for me now, it will be JavaScript. I am still struggling with its concept, syntax and scope. Since my strength is ruby, I have better understanding of OO side of JavaScript and that's not enough. I really need some help on this.
I thought that database and SQL interview went quiet well although I wasn't prepare for it. They asked me to build a library(a real library where we keep books and DVDs) and then find the books that checked out in 2014. Basic SQL command part went fairly well but I totally forget how to join the tables. The interviewer was kind enough to hold my hand to go all the way but I need to brush up these as well. Perhaps creating twitter schema challenge would be good
Because I've done the first question, the second one was easy. I have one table called 'parts' with parts name, price and then get revenue total from particular date. The tricky part was that the revenue is not the parts price. Because there will be delivery, tax and other costs being associated to the sales, I had to create new table called prices and stored these. This is one of the good parts of the interview.
There was one 'cultural' interview with a front-end engineer. I explain about my experience with SASS and other CSS frameworks which I think mean much but wasn't bad. It may not be a good idea to play with some front end CSS tools.
Overall, I am pretty happy with the experience. After all, this was my first engineering interview! Everyone was very nice and made me comfortable. The only complaint was that they didn't provide me lunch (or perhaps nice to offer some break) during 3+ hours interview so I wasn't able to focus much on last part of the interview. I also drink way too mcuh water (because I was extremely hungry and nervous) so I have this 'want-to-go-bathroom' kind of feeling for awhile. Very Important Lessons Learned. Eat plenty of food before an interview and don't drink too much water during an interview.

.small[from original slides by Tristan Mary-Huard] ] .date[ ### Shandong University, Weihai (CN)
Summer School 2023 ] --- --- class: middle, inverse, center # Warm-up ## Introducing the Fisher distribution --- ## Prerequesites: Fisher distribution Let `\(Z_1\)` and `\(Z_2\)` be two positive random variables such that - `\(Z_1\sim\chi^2(n_1)\)`, - `\(Z_2\sim\chi^2(n_2)\)`, - `\(Z_1\perp Z_2\)`. Define `$$F = \frac{Z_1/n_1}{Z_2/n_2}$$` -- Then `\(F\)` is said to follow a Fisher distribution with degrees of freedom `\(n_1\)` and `\(n_2\)`. One notes `$$F \sim \F(n_1,n_2)$$` --- ## Example 1: Infection Back to the phage infection example. Assume now that if at least 90% of the bacteria colony is infected then the biologist applies a treatment to fight the infection. What decision rule should be applied ? ``` 2 2 2 2 3 3 2 4 1 1 5 1 3 1 1 5 1 1 4 2 ``` .blue[Objective] Perform a test to decide whether the proportion of infected bacteria is higher than `\(90\%\)` or not. --- ## Modeling Denote `\(X_i\)` the number of phages obtained for the `\(i^{th}\)` bacterium. - One assumes that bacteria are independent: `\(X_1 \perp X_2 \perp \dots \perp X_{n},\quad\text{with } n= 20\)` - Measurements are discrete `\(X_1,..., X_{n} \sim \mathcal{P}(\bullet), \text{ i.i.d}\)` - The infection level is unknown `\(X_1,..., X_{n} \sim \mathcal{P}(\lambda), \text{ i.i.d}\)` --- ## Hypotheses Hypotheses *must* be formulated such that they *concern a parameter* of the model. Here the model is `$$X_1,..., X_{n} \sim \mathcal{P}(\lambda), \text{ i.i.d}$$` Consequently the hypotheses should concern `\(\lambda\)`. -- `$$\begin{eqnarray*} \hspace{-0.8cm}\text{Proportion of infected bacteria } \geq \text{90\%} &\Rightarrow& P(X>0)\geq 0.9 \\ &\Rightarrow& P(X=0)\leq 0.1 \\ &\Rightarrow& e^{-\lambda}\leq 0.1 \\ &\Rightarrow& \lambda\geq -\ln(0.1) \\ &\Rightarrow& \lambda\geq \lambda_0 (=2.3026) \\ \end{eqnarray*}$$` -- Hence `$$H_0: \{\lambda\leq \lambda_0\} \quad \text{vs} \quad H_1: \{\lambda\geq \lambda_0\}$$` --- ## Estimation Starting point: derive the ML estimator for the quantity of interest. `$$\begin{eqnarray*} Lik_\lambda(x_1,...,x_n) &=& \prod_{i=1}^n f_\lambda(x_i) \quad\text{(i.i.d. assumption)}\\ &=& \prod_{i=1}^n \frac{\lambda^{x_i}}{x_i!}e^{-\lambda} \\ \Rightarrow LLik_\lambda(x_1,...,x_n) &=& \log(\lambda)\sum_{i=1}^{n}x_i - \sum_{i=1}^{n}\log(x_i!) - n\lambda \end{eqnarray*}$$` .blue[Derivation] `$$\frac{\partial LLik_\lambda(x_1,...,x_n)}{\partial \lambda}= \frac{1}{\lambda}\sum_{i=1}^n x_i -n$$` Setting the derivative at 0, one gets: `\(\widehat{\lambda} = \frac{1}{n}\sum_{i=1}^n x_i=\bar{x}\)`. --- ## Decision rule Should be of the form `$$\text{If } \hat{\lambda}\geq s \text{ then reject } H_0$$` One needs to choose threshold `\(s\)`. .blue[Type I error control] Find `\(s\)` such that `\(P_{H_0}(\overline{X}\geq s)\leq \alpha\)` `\(\Rightarrow\)` Requires the (possibly approximate) distribution of `\(\overline{X}\)`. One has: `$$\begin{eqnarray*} n\overline{X} \sim \P(n\lambda) \quad \text{ and/or } \quad \sqrt{n}\frac{\overline{X}-\lambda}{\lambda} \overset{approx}{\sim} \N(0,1) \end{eqnarray*}$$` .blue[Under `\(H_0\)`]: One has `\(\lambda \in [0,\lambda_0]\)`, still the `\(H_0\)` distribution of `\(\overline{X}\)` is not fully known... --- ## Worst case scenario Which value of `\(\lambda \in [0,\lambda_0]\)` leads to the worst (i.e. the max) value of `\(P_{H_0}(\overline{X}\geq s)\)` ? ![](06_Tests_files/figure-html/unnamed-chunk-3-1.png)<!-- --> -- Worst value: `\(\lambda =\lambda_0\)` ! --- ## Back to the decision rule Considering the worst case scenario, one looks for `\(s\)` such that `$$P_{\lambda_0}\left( \overline{X}\geq s \right)\leq \alpha \Rightarrow P_{\lambda_0} \left( n\overline{X}\geq ns \right)\leq \alpha$$` Choose `\(ns = q_{n\lambda_0,1-\alpha} \Rightarrow s = \frac{q_{n\lambda_0,1-\alpha}}{n}\)`, .blue[Application] - `\(\widehat{\lambda}=\)` 2.3 - `\(n=\)` 20 - `\(\alpha= 0.05\)` - `\(q_{n\lambda_0,1-\alpha}=\)` 57 `\(\Rightarrow s=\)` 2.85 -- .blue[Conclusion ?] One does not reject the hypothesis that the proportion of infected bacteria is lower than 90\% --- ## Power of a test procedure Recall that the test procedure is design such that: - T1E is controlled at a given level, - T2E is minimum given T1E is controlled. T2E is minimum `\(\Rightarrow\)` `\(P_{H_1}( \text{accept } H_0)\)` is minimum `\(\Rightarrow\)` `\(P_{H_1}(\text{reject} H_0)\)` is maximum. `\(P_{H_1}(\text{reject } H_0)\)` is the ability to reject `\(H_0\)` when it false. This key quantity is called the __power__ of the test procedure.

THE FABULOUS BAKER BOYS A film review by Kevin Romano Copyright 1989 Kevin Romano
This film has a lot going for it and a lot not going for it. It has a great beginning and ending, pieced together with a yawn-filled middle section. It was written and directed by the same man, whose name I don't remember. Anyway, let me explain myself.
Traditional screenplay format allows for a beginning, a middle and an ending. The middle section is the longest because it has to carry the weight of the dramatic development of the theme, which has been proposed in the beginning and will be resolved in the ending. The main trouble with the writing of the screenplay for THE FABULOUS BAKER BOYS is that there is almost no development in the middle section. It's almost as if the film could have gone from beginning to ending for all the development that takes place in the middle. It's not that there isn't any, but that it is so meager and rather unconvincing. At one point I was wishing the film would hurry up and get over. Don't take this to mean you should avoid this film, because that would be a mistake. The film has lots of other things going for it.
Although Hollywood nepotism has brought us lots of people we'd just as soon forget about. I don't count Lloyd Bridges' sons, Jeff and Beau, amongst them. Jeff Bridges has become a terrific actor. Unfortunately, in this film the director does a miserable job of bringing out his character's weaknesses - weaknesses on which the plot rests. Beau Bridges, on the other hand, does a fabulous job in his part. In fact, when he is missing from the middle section of the film it begins to drag. He is completely convincing and I recommend anyone who takes an interest in acting to watch him in this film. His performance and the direction of his character are first class.
Michelle Pfeiffer, too, does a top-notch job of acting - and, rather surprisingly, she can also sing. It's wonderful to watch actors like Jeff Bridges and Michelle Pfeiffer develop their acting skills over time. It makes you want to go see what new thing they will bring to the screen next time. Only a few other actors have this refreshing approach. I refer to people like Meryl Streep, Marlon Brando, Dustin Hoffman. Michelle, as we know, is a physically beautiful person.  Michelle does not come across in this film as the type of person you would want to have an off-hand fling with, even though she plays the part of an ex-call-girl. For me in this film she is definitely the bring home to mother type. Perhaps I should personally analyse why I feel that way. It's puzzling to me why I would want to bring Michelle's character home to mother while Michelle's performance is so, shall we say, 'worldly'. At any rate this brings up one very important reason why we the audience go to movies in the first place. That is, of course, to learn about ourselves.
There's a lot of very nice minor touches in this film; some decent music, a very nice crane shot near the beginning, a convincing bit actress in a bedroom scene, also in the beginning, some fuuny comedy, as well as a wonderful "showdown" scene between the Baker boys. There are also some nasty plot holes to watch out for.
I feel I have to add one more objection and that is, overall, the plot, its development, and resolution turn out to cost the characters next to nothing. The film has a happy, upbeat ending. I like that. What I don't like is when the decisions the characters make in a film don't cost them anything. As we know there are no free lunches in life. We, as Americans, don't expect any. Decisions we make often cause the course of our entire lives to change. There is pain involved - a failing business, an unhappy choice of profession, a divorce, forced separation from loved ones - on and on. THE FABULOUS BAKER BOYS is a little too neat, too pat, too removed from the consequences of our choices for my taste.
So what I suggest is that you go see this movie, even though it is uneven. It has things to not recommend it, but lots that do. It's one of those films that you can learn from. I would especially have liked to have strangled the director's ideas for the (un)development of Jeff Bridges' character. See if you agree; you'll have some very nice moments along the way.

Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5 however, many plants have adapted to thrive at pH values outside this range.

Hello, and welcome to the /r/cubers weekly competitions! If you're new, please read the entire post before competing! This is competition todo_comp_num, and will go until todo_deadline. There’s a rotation of 4 events to be held once a month: 5x5, BLD, Skewb, and Pyraminx. You can also request an event to be done! If you want an event in an upcoming competition, write it with your results. One event will be done per week. You must be able to do the event you're requesting. To compete: >1. Scramble your cube, in the event that you are doing, with the scrambles provided. For OLL, do the alg 5 times. >1. Using a timer, such as [cstimer] (http://cstimer.net/timer.php) or [qqtimer] (http://www.qqtimer.net/), time your 5 solves and record the results. You are given up to 15 seconds to inspect the cube for each event. >1. Post your results following the following format in order for your results to be accepted by the sorting program: >1. If you have a flair other than the default "Sub-X ...", you must include your username (without /u/) at the top of your results before your first event. If you do not have a flair or have a default, you do not need to include your username.  You must copy the events exactly as spelled/capitalized in the post below. Common mistakes (such as 2Gen rather that 2GEN) are recognized by the program, but if it's a unique one (say, Skoob instead of Skewb) then you probably won't get credited for the event. >1. Follow the event with a colon (:), which is then *directly* followed by the average for the event. After that and before the next event can include anything you'd like, like the times for that event and sidenotes. For instance, your comment could look like: >1. **10x10: 59.99** // (1:15.67), 1:02.11, 59.12, (56.88), 58.74 >1. That's right. 10x10 in under a minute. Get rekt. >1. Try to avoid typos in your averages, like accidental commas or decimals in the wrong spot. This can make things pretty ugly. If your times are taken down wrong due to something like this, PM /u/pimpedkoala. >1. Please put your times in the order they appear on the post, as it makes result taking faster and more accurate! >1. Competition results are taken 9:00PM EDT Sunday nights, so make sure to submit times by then! **Weekly Events:** > * 2x2 > * 3x3 > * 4x4 > * 3x3OH > * 2GEN > * LSE > * OLL **Weekly Rotation:** (one of these events will be used) > * 5x5 > * Skewb > * Pyraminx > * BLD **This Week's Bonus Events:** > * Square-1 > * Void Cube **In queue:** > * 2-3-4 Relay > * FMC > * Megaminx > * 3x3 Relay of 3 > * 3x3 Mirror blocks/Bump > * F2l > * 6x6x6 > * 4x4 OH > * 7x7x7 > * 3x3x4 > * 3x3x5 Anyway, good luck to all those competing, especially those with upcoming WCA competitions! **2x2:** > 1. > 1. > 1. > 1. > 1. **3x3:** > 1. > 1. > 1. > 1. > 1. **4X4:** > 1. > 1. > 1. > 1. > 1. **3x3OH:** (in this mode of solving, you can only solve with one hand) > 1. > 1. > 1. > 1. > 1. **todo_rotation_event** > 1. > 1. > 1. > 1. > 1. **todo_requested_event** > 1. > 1. > 1. > 1. > 1. **todo_requested_event** > 1. > 1. > 1. > 1. > 1. **2GEN:**(in this mode of solving, you can only do <R,U>, which has the moves R, R', R2, U, U', U2) > 1. > 1. > 1. > 1. > 1. **LSE:**(in this mode of solving, you can only do <M,U>, which has the moves M, M', M2, U, U', U2) > 1. > 1. > 1. > 1. > 1. **OLL:** This week, we're doing [OLL todo_oll_num] (http://algdb.net/Set/OLL/OLL%20todo_oll_number)!


The fact
implies that is
constant along a magnetic field line. At first glance, a magnetic line on an
irrational surface seems to sample all the points on the surface. This seems
to indicate that is a flux surface label for irrational surface.
However, must be a non-flux-surface-function so that it can provide a
suitable toroidal coordinate. I had once been confused by this conflict for a
long time. The key point to resolve this confusion is to realize that it is
wrong to say there is only one magnetic line on an irrational surface, i.e. it
is wrong to say a magnetic line on an irrational surface samples all the
points on the surface. There are still infinite number of magnetic field lines
that can not be connected with each other on an irrational surface. Then the
fact
does not imply that must be
the same on these different magnetic field lines. In fact, although

flux-surface along the perpendicular (to

(In GEM code, the radial coordinate is chosen to be the minor radius of magnetic surfaces on the low-field-side of the midplane, and the field-aligned coordinates used in the code are defined by , and , where and are constant quantities of length dimension, is a dimensionless constant.)
(check** may be wrong, In the practical use of the field-aligned coordinates, the coordinate, which is along the magnetic field line, can not be infinite, i.e., we can not follow a magnetic field for infinite distance. It must be truncated into a finite interval.
[check** may be wrong. **Next, I explain the practical use of the field-aligned coordinates in the flux-tube turbulence simulations. The flux-tube means a region that is in the vicinity of a magnetic line and follows the magnetic field line. On every magnetic surface, we follow the magnetic field line for a distance longer than the , where is the smallest parallel wave number included in the simulation.
**may be wrong** check**The perpendicular width of the flux-tube is determined by the width of coordinate, which is chosen so that the perpendicular width of the flux tube on a magnetic surface is much larger than the perpendicular wavelength of the turbulence. Then we can use the periodic condition at and where is the width of coordinate chosen by us. The radial range of the flux tube is chosen to be much larger than the largest radial wave-length of the turbulence. The radial profiles of all the equilibrium quantities are assumed to be constant and the effects of the radial gradient of the equilibrium quantities enter the model through the drive terms in the gyro-kinetic equation.**]
By the way, note that , i.e., the magnetic field lines are straight with zero slope on plane.

You see a door. It has a large glass panel in it, and you can see a mini office space inside. You try the door, but the handle won't even jiggle. You try to shake it harder, no change, except that now the whole door is making a shaking sound.
 "Did you need help with something?" The librarian that has approached you is a young lady. She has on some gray dress pants and a purple sweater. Her tone is friendly but firm. You let her know that you were looking around and saw this office area and wanted a closer look. "Sorry, this is a staff area, so it's not available for customers, but feel free to look through the glass if you like." With that, she smiles and walks back to the front desk.

Video: Huge Protest Breaks Out On Field Of Harvard-Yale Game
by Andrew HolleranThe second half of the Harvard-Yale game is currently being delayed. A massive student protest has broken out on the field at the Yale Bowl.
What appears to be hundreds of students are sitting at midfield, protesting climate change.
“This is an emergency,” one sign reads.
The game is under delay and based on the size of this protest, it’s unclear if it will resume anytime soon.
“At halftime of Harvard-Yale a sit in protesting climate issues has broken out on the field, at least delaying the second half and the way the protest is growing I would be shocked if the game continues,” Joel Sherman tweeted from the game.
The students are reportedly protesting their respective schools’ willingness to invest in oil and gas companies that contribute to climate crisis. The signs accuse the schools of being “complicit” in it.
Harvard is leading Yale, 15-3, at halftime.

This is sickening but if you needed any more convincing of how hard cyclists are:
The 32-year-old rode on, not realising he’d been stabbed, before a short time later noticing that he was bleeding from the chest, police said.


It is definitely a full house. I have been doing artwork since I was a small child. That gives me about 23 years of experience. I majored in art in high school and took a few college art courses. Most of my work is done in either pencil or airbrush mixed with color pencils. I have recently added designing and creating artwork on the computer.I have been selling my art for the last 3 years and have had my work featured on trading cards, prints and in magazines.I have sold in galleries and to private collectors from all around the world.I am always facing serious difficulties when it comes to selling my art works to Americans,they are always offering to pay with a US POSTAL MONEY ORDER,which is difficult for me to cash here in Netherland. I am looking for a representative in the states who will be working for me and will be willing to pay %10 for every transaction,which wouldnt affect ur present state of work,someone who would help me recieve payments from my customers in the states.These payments are in money order and it will be made payable to your name, so all you need do is cash the money order deduct your percentage and wire the rest back. It wouldnt cost you any amount,you are to receive payments which will be sent by my customers to you via fedex. If you are interested,please get back to me as soon as possible. Regards Daniel Williams


Forex - Major Currencies Remained Little Changed Amid Mixed Messages on Trade War
by Investing.comInvesting.com - Major currency pairs were little changed on Friday in Asia amid mixed messages on the Sino-U.S. trade progress.
The U.S. dollar index last traded at 97.835 by 1:05 AM ET (05:05 GMT), down 0.04%.
The Wall Street Journal reported that China has invited top U.S. trade officials including U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin to Beijing for a new round of face-to-face negotiations.
The report came one day after Reuters said a partial trade deal might not be signed this year.
While officials from China hinted that Beijing and Washington hinted earlier this month that the two sides are close to signing a deal, U.S. President Donald Trump comments last week that said he did not agree to roll back existing tariffs dampened hopes of a quick trade deal.
The USD/CNY pair, which is usually sensitive to trade news, was little changed at 7.0343.
"Headline fatigue has set in," said Ray Attrill, National Australia Bank's head of FX strategy, in a Reuters report.
"With the constant barrage of seemingly contradictory stuff, the market's given up trying to second-guess...seeing is believing, and we'll trade it once we know what's happening."
On the data front, flash purchasing managers index from Germany, the Eurozone, Britain and the United States are all due later on Friday.
The AUD/USD pair and the NZD/USD pair both traded 0.1% higher.
The GBP/USD pair was also near flat at 1.2916.
The USD/JPY pair was unchanged at 108.62.

You make a right in an attempt to escape the Librarian Viking chasing you. You run directly into a shelf of children's books, and it falls on you. It was the Storytime collection; those are books librarians read to children at Storytime.
A storytime would have been lovely to experience. Maybe you should check the afterworld library to see if they have storytimes as well, because, You Are Dead!


The Challenge
YTF hired me as their Chief Storytelling Officer to craft visual narratives around the organization and programs. In that capacity, I was given complete autonomy and worked with minimal supervision.
The Process
I would not have been able to distill YTF's story unless I fully understood the complexities of it. Accordingly, I invested time into truly understanding the organization and its work.
This meant talking to the founder and CEO as well as field staff, interviewing beneficiaries, analyzing relevant program documents, and closely reading content on their site.
In addition, I carried out extensive research to understand the problems that the organization is addressing. This meant finding and reading research papers, white papers, and blog posts.
After I completed my research, I designed visuals that explained the problems and programs. Designing visuals consisted of three steps: 1) deciding what we wanted to say 2) deciding how we wanted to say it 3) working on visual design.
Part of a designer’s job is to become a storyteller and an editor. In that sense, my experience as a storyteller at YTF has been immensely helpful in helping me grow as a designer.
Infographics
Prominent non-profit organizations such as Girl Effect, Food and Agriculture Organization of the United Nations, Ashoka, Schwab Foundation, and Cherie Blaire Foundation picked up and re-tweeted content I created.
Here are the infographics that Girl Effect retweeted.
Here are more mini-infographics I designed.
Here is an infographic I designed on why the organization invests in women. I owned the whole design process from content development to visual design.
I also designed visually appealing content to share on social media.


Resize browser to smallest size and reload page, then resize window back to whole screen. You`ll see low resolution assets and canvas. This happens because FlashJS detects device or window size and loads corresponding assets. So for iPhone you`ll have lower resolution choosen and higher one for desktop. Virtual coordinates are also interesting feature of FlashJS. This means that after resolution changed - coordinates inside of stage kept same. You dont need to add something like myObject.x = newX * scale, everything is already done inside of engine in the way you`ll have united coordinate measure for all resolutions.

void lib_call(MPI_Comm comm) { int me, done = 0; MPI_Status status; MPI_Comm_rank(comm, &me); if(me == 0) while(!done) { MPI_Recv(..., MPI_ANY_SOURCE, MPI_ANY_TAG, comm, &status); ... } else { /* work */ MPI_Send(..., 0, ARBITRARY_TAG, comm); .... } #ifdef EXAMPLE_2C /* include (resp, exclude) for safety (resp, no safety): */ MPI_Barrier(comm); #endif }The above example is really three examples, depending on whether or not one includes rank 3 in list_b, and whether or not a synchronize is included in lib_call. This example illustrates that, despite contexts, subsequent calls to lib_call with the same context need not be safe from one another (colloquially, ``back-masking''). Safety is realized if the MPI_Barrier is added. What this demonstrates is that libraries have to be written carefully, even with contexts. When rank 3 is excluded, then the synchronize is not needed to get safety from back masking.
Algorithms like ``reduce'' and ``allreduce'' have strong enough source selectivity properties so that they are inherently okay (no backmasking), provided that MPI provides basic guarantees. So are multiple calls to a typical tree-broadcast algorithm with the same root or different roots (see [45]). Here we rely on two guarantees of MPI: pairwise ordering of messages between processes in the same context, and source selectivity --- deleting either feature removes the guarantee that backmasking cannot be required.
Algorithms that try to do non-deterministic broadcasts or other calls that include wildcard operations will not generally have the good properties of the deterministic implementations of ``reduce,'' ``allreduce,'' and ``broadcast.'' Such algorithms would have to utilize the monotonically increasing tags (within a communicator scope) to keep things straight.
All of the foregoing is a supposition of ``collective calls'' implemented with point-to-point operations. MPI implementations may or may not implement collective calls using point-to-point operations. These algorithms are used to illustrate the issues of correctness and safety, independent of how MPI implements its collective calls. See also Section Formalizing the Loosely Synchronous Model .

module ActiveRecordWhereAssoc::RelationReturningMethods
This module adds new variations of #where
to your Models/relations/associations/scopes. These variations check if an association has records, so you can check if a Post
has any Comments
.
These variations return a new relation (just like #where
) so you can chain them with other scoping methods such as #where
, #order
, #limit
, more of these variations, etc.
The arguments common to all methods are documented here at the top.
For brevity, the examples are all directly on models, such as User, Post, Comment, but the methods are available and behave the same on:
-
associations:
my_user.posts.where_assoc_exists(:comments)
-
relations:
Posts.where(serious: true).where_assoc_exists(:comments)
-
scopes: (On the Post model)
scope :with_comments, -> { where_assoc_exists(:comments) }
-
models:
Post.where_assoc_exists(:comments)
In short: Anywhere you could use #where, you can also use the methods presented here. This includes with ActiveRecord’s #or method.
Introduction to this gem introduces each features of the gem clearly.
The gem’s README.md contains known limitations and usage tips.
Many examples are available, including the generated SQL queries.
If you need extra convincing to try this gem, this document with the problems of the other ways of doing this kind of filtering should help: alternatives’ problems.
Association¶ ↑
The associations referred here are the links between your different models. They are your #belongs_to
, #has_many
, #has_one
, #has_and_belongs_to_many
.
This gem is about getting records from your database if their associations match (or don’t match) a certain condition (which by default is just to exist).
Every method here has an association_name parameter. This is the association you want to check if records exists.
# Posts with at least one comment Post.where_assoc_exists(:comments) # Posts with no comments Post.where_assoc_not_exists(:comments)
If you want, you can pass an array of associations. They will be followed in order, just like a has_many :through would.
# Posts which have at least one comment with a reply # In other words: Posts which have at least one reply reachable through his comments Post.where_assoc_exists([:comments, :replies])
Condition¶ ↑
After the association_name
argument, you can pass conditions on your association to specify which of its records you care about. For example, you could only want Posts that have a comment marked as spam, so all you care about are comments marked as spam.
Another way to look at this is that you are filtering your association (using a #where
) and checking if a record of that association is still found, and you do this for each of you records.
This condition
argument is passed directly to #where
, so you can pass in the following:
# Posts that have at least one comment considered as spam # Using a Hash Post.where_assoc_exists(:comments, is_spam: true) # Using a String Post.where_assoc_exists(:comments, "is_spam = true") # Using an Array (a string and its binds) Post.where_assoc_exists(:comments, ["is_spam = ?", true]) If the condition is blank, it is ignored (just like +#where+ does).
Note, if you specify multiple associations using an Array, the conditions will only be applied to the last association.
# Users which have a post that has a comment marked as spam. # is_spam is only checked on the comment. User.where_assoc_exists([:posts, :comments], is_spam: true)
If you want something else, you will need to use a block (see below) to nest multiple calls.
# Users which have a post made in the last 5 days which has comments User.where_assoc_exists(:posts) { where("created_at > ?", 5.days.ago).where_assoc_exists(:comments) }
Block¶ ↑
The block is used to add more complex conditions. The effect is the same as the condition parameter. You are specifying which records in the association you care about, but using a block lets you use any scoping methods, such as #where
, #joins
, nested #where_assoc_*
, scopes on the model, etc.
Note that using #joins
might lead to unexpected results when using #where_assoc_count
, since if the joins adds rows, it will change the resulting count. It probably makes more sense to, again, use one of the where_assoc_*
methods (they can be nested).
There are 2 ways of using the block for adding conditions to the association.
- A block that receives one argument
-
The block receives a relation on the target association and return a relation with added filters or may return nil to do nothing.
# These are all equivalent. Posts which have a comment marked as spam # Using a where for the added condition Post.where_assoc_exists(:comments) { |comments_scope| comments_scope.where(is_spam: true) } # Applying a scope of the relation Post.where_assoc_exists(:comments) { |comments_scope| comments_scope.spam_flagged } # Applying a scope of the relation, using the &:shortcut for procs Post.where_assoc_exists(:comments, &:spam_flagged)
- A block that receives no argument
-
Instead of receiving the relation as argument, the relation is used as the “self” of the block. Everything else is identical to the block with one argument.
# These are all equivalent. Posts which have a comment marked as spam # Using a where for the added condition Post.where_assoc_exists(:comments) { where(is_spam: true) } # Applying a scope of the relation Post.where_assoc_exists(:comments) { spam_flagged }
The main reason to use a block with an argument instead of without one is when you need to call methods on the self outside of the block, such as:
Post.where_assoc_exists(:comments) { |comments| comments.where(author_id: foo(:bar)) } Post.where_assoc_exists(:comments) { |comments| comments.where(author_id: self.foo(:bar)) } # In both cases, using the version without arguments would not work, since the #foo # would be called on the scope that was given to the block, instead of on the caller # of the #where_assoc_exists method. # THESE ARE WRONG! Post.where_assoc_exists(:comments) { where(author_id: foo(:bar)) } Post.where_assoc_exists(:comments) { where(author_id: self.foo(:bar)) } # THESE ARE WRONG!
If both condition
and block
are given, the conditions are applied first, and then the block.
Options¶ ↑
Some options are available to tweak how queries are generated. The default values of the options can be changed globally:
# Somewhere in your setup code, such as an initializer in Rails ActiveRecordWhereAssoc.default_options[:ignore_limit] = true
Or you can pass them as arguments after the condition
argument.
Post.where_assoc_exists(:comments, "is_spam = TRUE", ignore_limit: true) # Because this is 2 consecutive hashes, must use the +{}+ Post.where_assoc_exists(:comments, {is_spam: true}, ignore_limit: true)
Note, if you don’t need a condition, you must pass nil as condition to provide options:
Post.where_assoc_exists(:comments, nil, ignore_limit: true)
:ignore_limit option¶ ↑
When true, #limit
and #offset
that are set from default_scope, on associations, and from #has_one
are ignored.
Removing the limit from #has_one
makes them be treated like a #has_many
.
Main reasons to use ignore_limit: true
-
Needed for MySQL to be able to do anything with
#has_one
associations because MySQL doesn’t support sub-limit.
See MySQL doesn’t support limit
Note, this does mean the#has_one
will be treated as if it was a#has_many
for MySQL too. -
You have a
#has_one
association which you know can never have more than one record and are dealing with a heavy/slow query. The query used to deal with#has_many
is less complex, and may prove faster. -
For this one special case, you want to check the other records that match your has_one
:never_alias_limit option¶ ↑
When true, #where_assoc_*
will not use #from
to build relations that have #limit
or #offset
set on default_scope or on associations or for #has_one
.
This allows changing the from as part of the conditions (such as for a scope)
Main reasons to use this: you have to use #from
in the block of #where_assoc_*
method (ex: because a scope needs #from
).
Why this isn’t the default:
-
From very few tests, the aliasing way seems to produce better plans.
-
Using aliasing produces a shorter query.
:poly_belongs_to option¶ ↑
Specify what to do when a polymorphic belongs_to is encountered. Things are tricky because the query can end up searching in multiple Models, and just knowing which ones to look into can require an expensive query. It’s also possible that you only want to search for those that match some specific Models, ignoring the other ones.
- :pluck
-
Do a
#pluck
in the column to detect to possible choices. This option can have a performance cost for big tables or when the query if done often, as the#pluck
will be executed each time. It is important to note that this happens when the query is prepared, so using this with methods that return SQL (such asSqlReturningMethods#assoc_exists_sql
) will still execute a query even if you don’t use the returned string. - model or array of models
-
Specify which models to search for. This avoids the performance cost of
#pluck
and can allow to filter some of the choices out that don’t interest you.
Note, these are not instances, it’s actual models, ex:[Post, Comment]
- a hash
-
The keys must be models (same behavior as an array of models).
The values are conditions to apply only for key’s model. The conditions are either a proc (behaves like the block, but only for that model) or the same things#where
can receive. (String, Hash, Array, nil). Ex:List.where_assoc_exists(:items, nil, poly_belongs_to: {Car => "color = 'blue'", Computer => proc { brand_new.where(core: 4) } })
- :raise
-
(default) raise an exception when a polymorphic belongs_to is encountered.
Basic methods
↑ topPublic Instance Methods
Returns a new relation with a condition added (a #where
) that checks if an association of the model exists. Extra conditions the associated model must match can also be specified.
You could say this is a way of doing a #select

Returns a new relation with a condition added (a #where
) that checks if an association of the model does not exist. Extra conditions the associated model that exists must not match can also be specified.
This the exact opposite of what #where_assoc_exists
does, so a #where_assoc_not_exists
with the same arguments will keep every records that were rejected by the #where_assoc_exists
.
You could say this is a way of doing a #reject
that uses associations of your model on the SQL side, but faster and more concise.
Examples (with an equivalent ruby #reject
)
# Posts that have no comments Post.where_assoc_not_exists(:comments) Post.all.reject { |post| post.comments.exists? } # Posts that don't have comments marked as spam (but might have unmarked comments) Post.where_assoc_not_exists(:comments, is_spam: true) Post.reject { |post| post.comments.any? {|comment| comment.is_spam } } # Posts that don't have comments that have replies (but can have comments that have no replies) Post.where_assoc_exists([:comments, :replies]) Post.reject { |post| post.comments.any? {|comment| comment.replies.exists? } }

Complex method
↑ topPublic Instance Methods
Returns a new relation with a condition added (a #where
) that checks how many records an association of the model has. Extra conditions the associated model must match can also be specified.
This method is a generalization of #where_assoc_exists
and #where_assoc_not_exists
. It does the same thing, but can be more precise over how many records should exist (and match the extra conditions) To clarify, here are equivalent examples:
Post.where_assoc_exists(:comments) Post.where_assoc_count(1, :<=, :comments) Post.where_assoc_not_exists(:comments) Post.where_assoc_count(0, :==, :comments)
But these have no equivalent:
# Posts with at least 5 comments Post.where_assoc_count(5, :<=, :comments) # Posts with less than 5 comments Post.where_assoc_count(5, :>, :comments)
You could say this is a way of doing a #select
that #count
the associations of your model on the SQL side, but faster and more concise.

- left_operand
-
1st argument, the left side of the comparison.
One of:-
a number
-
a string of SQL to embed in the query
-
a range (operator must be :== or :!=), will use BETWEEN or NOT BETWEEN
supports infinite ranges and exclusive end# Posts with 5 to 10 comments Post.where_assoc_count(5..10, :==, :comments)
# Posts with less than 5 or more than 10 comments Post.where_assoc_count(5..10, :!=, :comments)
-
- operator
-
The operator to use, one of these symbols:
:< :<= :== :!= :>= :>
- association_name
-
The association that must have a certain number of occurrences
Note that if you use an array of association names, the number of the last association is what is counted.# Users which have received at least 5 comments total (can be spread on all of their posts) User.where_assoc_count(5, :<=, [:posts, :comments])
- condition
-
Extra conditions the association must match to count
See Condition atRelationReturningMethods
- options
-
Options to alter the generated query
See Options atRelationReturningMethods
- &block
-
More complex conditions the associated record must match (can also use scopes of the association’s model)
See Block atRelationReturningMethods
The order of the parameters may seem confusing. But you will get used to it. It helps to remember that the goal is to do:
5 < (SELECT COUNT(*) FROM ...)
So the parameters are in the same order as in that query: number, operator, association.
To be clear, when you use multiple associations in an array, the count you will be comparing against is the total number of records of that last association.
# The users that have received at least 5 comments total on all of their posts # So this can be from one post that has 5 comments of from 5 posts with 1 comments User.where_assoc_count(5, :<=, [:posts, :comments]) # The users that have at least 5 posts with at least one comments User.where_assoc_count(5, :<=, :posts) { where_assoc_exists(:comments) }
You can get the SQL string of the condition using SqlReturningMethods#compare_assoc_count_sql
. You can get the SQL string for only the counting using SqlReturningMethods#only_assoc_count_sql
.
# File lib/active_record_where_assoc/relation_returning_methods.rb, line 402 def where_assoc_count(left_operand, operator, association_name, conditions = nil, options = {}, &block) sql = ActiveRecordWhereAssoc::CoreLogic.compare_assoc_count_sql(self.klass, left_operand, operator, association_name, conditions, options, &block) where(sql) end


--- layout: post title: Theseus 1.0 post_id: 22 categories: - announcements - projects date: 2010-12-20 08:29:00.000000000 -07:00 author: Jamis permalink: 2010/12/20/theseus-1-0.html summary: > A command-line app for generating mazes is introduced. Various mazes are shown by way of demonstration ---
Whenever I tackle a new programming language, I need a project to apply it to. Just experimenting with syntax isn’t enough; there has to be a real context for it, or it doesn’t stick. Some years ago I discovered a great “default” project: generating mazes.
Mazes explore a lot of the nooks and crannies of a language: random numbers, decision making, recursion and/or iteration, and several data structures, at the very least. If you want to be able to tweak your mazes without changing code, you then need to learn about passing arguments via the command-line, or environment variables, or even configuration files. Add the possibilty of actually displaying the maze and you introduce string manipulation and console IO (if emitting ASCII art), or graphics libraries and file IO (if writing to an image file).
The actual algorithms behind building a maze are pretty straightforward, which is ideal.
This has served me well for several years. C++, C#, Haskell, Erlang, Scala, Io, and even Prolog! But I realized I’d never actually tried it in my favorite language: Ruby.
So, I gave it a try. And I had a blast. It kind of took on a life of its own, with features evolving as fast as I could implement them. The result: Theseus.
I released Theseus 1.0 last night, and it is available for installation via RubyGems. (You’ll get syntax errors if you try it on Ruby 1.8, though, so beware.) Feel free to fork it on GitHub, too. It’s in the public domain, so you can do whatever you want with it.
I am rather ashamed of the lack of tests, though. I realized as I was building this out that I need a good lesson in real test-driven development. I had a difficult time seeing how to test something like this. I’m going to be reading Kent Beck’s book next, I think.
Here are some examples of stuff that Theseus can do:
Give it a try! All of these examples were generated using the command-line utility that is installed with the gem. It’s remarkably flexible.

'Casual' video games are serious business: "The developers are gamers themselves and always want to push the envelope on the games they make," Olhava adds. "But if they try to make something bigger or more complex -- and people don't play it or buy it -- at the end of the day, business will win out. The developers will get the hint quickly enough that this isn't what the casual gamer wants."


Liberal win in Montreal riding stands after Bloc withdraws recount request
by The Canadian PressOTTAWA -- A judicial recount in the Montreal riding of Hochelaga has been cancelled midway through the process.
The Bloc Quebecois asked for the recount following the initial count on election day on Oct. 21, saying there was a discrepancy between the number of ballots in the ballot boxes and the listed results.
The Bloc's candidate, Simon Marchand, finished 319 votes behind Liberal Soraya Martinez Ferrada.
In the midst of the recount, however, the Bloc conceded the loss and withdrew its request.
There are two other judicial recounts underway in Quebec and British Columbia.
The NDP requested a recount in Port Moody-Coquitlam and the Bloc requested one in the riding of Quebec.

In this repo we were given starter code to modify and make accessible. By means of refactoring. When you refactor existing code it makes improvements without ever changing it.
Github RepositoryIn this repo our job was to pretend that we were employee's with access to sensitive data. We were given starter Java Script code to modify to randomly generate a password that met certain criteria. We had to create a strong password that provides greater security.
Github RepositoryIn this repo our job was to create a simple calendar application that allows a user to save events for each hour of the day. We were given html and CSS starter code. Withe the expectation to build the JS code from scratch. The planner should is supposed to run in the browser featuring updated HTML and CSS powered by jQuery.A key feature to this repo was we also had to use the Moment.js library to set our dates and time.
Github RepositoryProject 1 was to build web applications from scratch. With a team, to conceive and execute a design by integrating data received from multiple server-side API requests. While working collaboratively, to learn agile development methodologies and implement features and bug fixes using the git branch workflow and pull requests.
