S I L V E RL I G HT P IANO

Tempo fa, ho avuto la fortuna di studiare questa demo1 sull'utilizzo del
framework Xna per la creazione di giochi su Windows Phone In particolare
Phone.
viene creato un piano col quale divertirsi a suonare.
Ho voluto cimentarmi nel creare una demo simile, e per evitare di copiare, mi
sono imposto l'utilizzo del framework Silverlight per Windows Phone. Ecco una
breve descrizione.

T AS TI E RA

Per disegnare la tastiera ho disposto 13 Button (corrispondenti a 13 note)
all'interno di un Canvas. Di seguito puoi vedere un estratto del file
MainPage.xaml:

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
="ContentPanel" ="12,0,12,0">
<Canvas x:Name="keyboard">
="keyboard">
<Button Canvas.Left="29" Canvas.Top="6" Name="c" />
="29"
<Button Canvas.Left="107" Canvas.Top="6" Name="d" />
="107"
<Button Canvas.Left="185" Canvas.Top="6" Name="e" />
="185"
<Button Canvas.Left="263" Canvas.Top="6" Name="f" />
="263"
<Button Canvas.Left="341" Canvas.Top="6" Name="g" />
="341"
<Button Canvas.Left="419" Canvas.Top="6" Name="a" />
="419"
<Button Canvas.Left="497" Canvas.Top="6" Name="b" />
="497"
<Button Canvas.Left="575" Canvas.Top="6" Name="c8" />
="575"

Il risultato è quello mostrato nella figura riportata sopra.

$http://www.webalice.it/nmastrapasqua/ Per simulare il movimento del tasto ho utilizzato l'effetto tilt disponibile nel Silverlight Toolkit per Windows Phone: toolkit:TiltEffect.IsTiltEnabled="true" CO DE B E HI ND Per avere la magia dell'input multi-touch, ho utilizzato l'interfaccia di basso livello Touch.FrameReported; questo è il costruttore nel file MainPage.xaml.cs public MainPage() { InitializeComponent(); Touch.FrameReported += new TouchFrameEventHandler(Touch_FrameReported); } Il metodo Touch_FrameReported, ottiene una lista dei punti di contatto e per ognuno di essi, controlla l'eventuale sovrapposizione con i Button che rappresentano i tasti. Nel caso ci sia sovrapposizione, emette il suono corrispondente al tasto. In questo modo, si possono suonare anche gli accordi!

How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow

��

Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits. To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups. Technology For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did. While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis. Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad. Age and Gender When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same. Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers. Race Affects Attitudes As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork

Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.

Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray

��

1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework. 2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections. 3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.
