As Lead Economist (Data Scientist), I leveraged data using tools such as R, Python, and SQL to guide executive decision making. Some project highlights include:
      o Yearly student enrolment forecasting – Using a cohort-survival model, I forecast the number of students that will be enrolled in B.C. public schools. This model guides the allocation of capital to school districts.
      o Developed a workforce attrition model that is used to inform teacher supply and demand planning across the province. I use R to apply machine learning models as part of a larger simulation model used forecast yearly attritions from the K-12 education workforce and the demographics of the workforce in each forecast year.
      o Partnered with Statistics Canada to use individual tax-file data on research related to student post-graduation outcomes and career trajectories. This involves using R to work with very large (larger than memory) data sets.
      o Scraping web data and email engagement data using Python. These scripts have been used to build data capacity at the ministry, and this newly acquired data is being used to improve communication between the ministry and teachers around the province.
      o The use of natural language processing (NLP) to analyze open text survey responses on the impact that the COVID-19 pandemic had on students, parents, and staff in a sample of B.C. public schools.
      o Principal author of the B.C. Education Sector Workforce Report, a lengthy public facing document that provides a cohesive review of the workforce in B.C.’s K-12 education sector. While authoring this report, I developed a large directory of SQL queries that are used as the basis of all workforce related reporting done by the ministry.

Coinbase: Earning report | August 9, 2022

Coinbase Reports 63 Percent Drop in Revenue Amid Industry Slump

Here is the link.

The cryptocurrency exchange lost more than $1 billion in the second quarter.

By David Yaffe-Bellany

 When the cryptocurrency exchange Coinbase went public in April 2021, it was a triumphant moment for the nascent crypto industry.

But the company has endured a grim 2022, grappling with a crypto market crash that has tanked its stock price and forced it to lay off hundreds of employees.

Those struggles continued on Tuesday when Coinbase reported a 63 percent decline in revenue in the second quarter and swung to a $1.1 billion loss from a year ago.

 

Blaming the “fast and furious” crypto downturn, the company said revenue was $808 million, down from $2.2 billion a year earlier. Its monthly customer total rose to nine million from 8.8 million last year, but was down from 9.2 million in the last quarter. Coinbase also predicted that its user numbers would continue to fall over the next three months.

In an earnings call on Tuesday, Brian Armstrong, Coinbase’s chief executive, emphasized the cyclical nature of crypto and pointed out that the company had survived previous downturns.

“It seems scary,” he said. “But it’s never as bad as it seems.”

The results illustrated the stark challenges facing Coinbase at a turbulent moment for the crypto industry. The prices of the leading digital currencies crashed in May and June as a series of experimental crypto ventures collapsed, plunging investors into financial ruin. The crash has led to layoffs across the industry, dampening the excitement that surged last fall when the price of Bitcoin reached a record high.

As part of the industry meltdown, Coinbase’s stock price has fallen about 75 percent since November. The company’s success is largely tied to the fluctuations of the broader crypto market. In the second quarter, more than 80 percent of its revenue came from trading fees it charged customers to buy and sell digital assets like Bitcoin and Ether.

In June, Coinbase laid off 18 percent of its staff, or about 1,100 employees. Mr. Armstrong said at the time that the company had “over-hired.”

 

Coinbase’s recent struggles have fueled concerns that it may be squandering its early lead in the industry, as competitors like Binance and FTX expand during the downturn.

Despite its early start, Coinbase has never had a strong foothold in the international market, and it recently botched an expansion effort in India. Its most hyped product launch of the year — a marketplace for the digital collectibles known as nonfungible tokens, or NFTs — drew little customer interest. And a hiring spree last year led to overspending and bloat, as the company’s expenses more than doubled.

“We probably could have grown slower over the last couple of years,” Mr. Armstrong said on the call.

Coinbase has also come under regulatory scrutiny. Last month, the Justice Department filed insider-trading charges against a former Coinbase employee. In a related action, the Securities and Exchange Commission said that it considered some of the digital coins listed on Coinbase’s exchange to be securities and, therefore, subject to regulation like stocks or bonds — a stance the company has objected to.

In a letter to shareholders on Tuesday, Coinbase said that the S.E.C. sent the company a “voluntary request for information” in May about that listing process. “We do not yet know if this inquiry will become a formal investigation,” the letter said.

Coinbase’s competitors appear to be faring better during the downturn. FTX, another crypto exchange, has had financial results that are “ballpark similar” to last year’s, according to its chief executive, Sam Bankman-Fried. Binance, the world’s largest exchange, announced in June that it was looking to fill 2,000 positions.

Still, Coinbase remains one of the most trusted and recognized crypto brands in the United States, known for its Super Bowl commercial featuring a bouncing QR code. Last week, the company announced a partnership with BlackRock, the world’s largest asset manager, to help institutional investors trade Bitcoin.

Introducing Money in Excel, an easier way to manage your finances - Microsoft 365 Blog

Here is the article. 

By 

• Arjun Tomar

Updated on May 23, 2022: Effective June 30, 2023, Money in Excel will no longer be supported. Please see our FAQ.

Managing personal finances can be a daunting prospect for most people, but having the right tools can help make it less challenging. While millions of people use Excel to track their budgets, manually updating a budget spreadsheet every month with the latest transactions can be a very time-consuming process. As organizing and tracking finances becomes a critical task for many of us, we want to help make managing your personal budget in Excel a more seamless experience. Today, with the launch of Money in Excel, we’re embarking on a journey to simplify your day-to-day money decisions to help you stay on track of your longer-term financial goals.

[interruption id=”234520″]

Manage your money—without ever leaving Excel

Money in Excel is a dynamic, smart template and add-in for Excel that allows you to securely connect your bank, credit card, investment, and loan accounts to Excel and automatically import your transaction and account information into an Excel spreadsheet.

If you’re a current Microsoft 365 Personal or Family subscriber, simply go to this link to download the template. Once downloaded, open the Excel template¹ and follow the on-screen prompts to connect your financial accounts using a secure third-party plugin supported by Plaid² (Plaid currently supports most major U.S. financial institutions). Once your account information is verified, the workbook will be updated with your latest transaction history³ and is now ready for use.

Now, let’s look at how Money in Excel can help simplify the task of managing your finances.

Keep track of your money

Once your financial accounts³ are connected, Money in Excel will automatically import your transaction information from all your accounts into one workbook. You no longer need to spend hours manually setting up a personal finance spreadsheet from scratch; Money in Excel does it for you in just a few seconds. And every time you want to update the workbook with the latest transactions, just click the Update button and get the latest snapshot of your transactions and accounts without ever leaving Excel.

Get closer to your financial goals

Once your transaction information is imported into Excel, it’s easy to track your spending habits to help stay on course and get closer to your financial goals. Use the “Snapshot” sheet to get an instant glimpse of how you’re spending across various categories such as groceries, household items, rent, and more. With the help of easy-to-read graphs, you can quickly track how your spending compares month over month. And to help ensure you are not caught unaware of any unwelcome transactions, Money in Excel will alert you to increases in your subscription fees, changes in bank and overdraft charges, or any big purchases that were posted during the month.

Easily customizable to suit your needs

We know people often choose Excel to manage their finances because it allows them to take a more personalized approach. With this in mind, we designed Money in Excel to be easily customizable to suit your needs and goals. For example, if a certain transaction does not fall within an existing spending category, you can simply add your own. If you want to perform a quick custom analysis, you can copy the relevant transactions into a new Excel sheet and use any of your favorite Excel features to do quick calculations. And while Money in Excel already comes with charts that have been created based on your transaction information—such as one for your recurring expenses—you can always create your own charts and tables and add them to the workbook.

From helping you track your monthly spending to alerting you about subscription price increases, Money in Excel makes it easy to manage your money. We hope that by using Money in Excel, organizing your finances becomes a more manageable and empowering experience. We can’t wait for you to try it out and share your feedback with us.

¹For the best experience, we recommend using Money in Excel on a PC or Mac. Optimal performance when using Windows 10 and Edge/Chrome browsers.
²Plaid is a third-party company that provides permissioned connections to financial accounts, at the user’s direction, to power Money in Excel.
³After granting permission for Plaid to connect a financial account with Money in Excel, Plaid will access the account’s balances, transaction history, and associated account information, like owner name and address. Plaid will not have access to your Microsoft 365 subscription login information and will not share financial institution login credentials with Microsoft. Contact Plaid at privacy@plaid.com or by clicking the support button at https://my.plaid.com/help to learn about options for managing your data with Plaid.

C# @ - Verbatim string lieterals

 

Literals

Literals are how you hard-code strings into C# programs. There are two types of string literals in C# - regular string literals and verbatim string literals. Regular string literals are similar to those in many other languages such as Java and C - they start and end with ", and various characters (in particular, " itself, \, and carriage return (CR) and line feed (LF)) need to be "escaped" to be represented in the string. Verbatim string literals allow pretty much anything within them, and end at the first " which isn't doubled. Even carriage returns and line feeds can appear in the literal! To obtain a " within the string itself, you need to write "". Verbatim string literals are distinguished by having an @ before the opening quote. Here are some examples of the two types of literal, and what they amount to:

Regular literal	Verbatim literal	Resulting string
"Hello"	@"Hello"	Hello
"Backslash: \\"	@"Backslash: \"	Backslash: \
"Quote: \""	@"Quote: """	Quote: "
"CRLF:\r\nPost CRLF"	@"CRLF: Post CRLF"	CRLF: Post CRLF

Note that the difference is only for the compiler's sake. Once the string is in the compiled code, there's no such thing as a verbatim string literal vs a regular string literal.
