If you work at Apple's One Infinite Loop headquarters in Cupertino as a computer programmer on an H-1B visa, you can can be paid as little as $52,229. That's peanuts in Silicon Valley. Average wages for a programmer in Santa Clara County are more than $93,000 a year, according to the U.S. Bureau of Labor Statistics.

However, the U.S. government will approve visa applications for Silicon Valley programmers at $52,229 -- and, in fact, did so for hundreds of potential visa holders at Apple alone.

To be clear, this doesn't mean there are hundreds of programmers at Apple working for that paltry sum. Apple submitted a form to the U.S. saying it was planning on hiring 150 computer programmers beginning June 14 at this wage. But it's not doing that.

The U.S. technology industry warned President Donald Trump that his immigration order will hurt the U.S. economy by making it more difficult for businesses to attract overseas workers. The administration's seven-country ban is, for the tech industry, a blinking caution sign to the world's highly skilled population delivering this message: Come here at your own risk.

Tech firms see the market for highly skilled workers as being "globally competitive," and any changes to immigration rules may inhibit their ability to recruit overseas. Most of these companies hire Indian nationals, who account for as many 70 percent of the H-1B visa holders.

Two hundred and fifty-one H-1B visa applications for people born in the seven banned countries were approved in fiscal year 2015 for computer-related jobs, according to a Computerworld analysis of government immigration data for that year. If new and renewed H-1B visas are counted for multiple years, the number will rise. The seven countries where the immigration ban would apply are Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen.

Donald Trump’s call for "extreme vetting" of visa applications, as well as the temporary suspension of immigration from certain countries, would raise fees and add delays for anyone seeking a visa, including H-1B visas, immigration experts said.

In particular, a plan by Trump, the Republican presidential candidate, to stop issuing visas -- at least temporarily -- "from some of the most dangerous and volatile regions of the world" may make it difficult for a significant number of people to get visas.

Data assembled by Computerworld through a Freedom of Information Act request shows foreign workers come from all corners of the world, including "dangerous and volatile regions." Trump outlined his immigration enforcement plan in a speech Monday.

Microsoft has jumped into the free, self-service data analysis space with Power BI.

Power BI offers basic data wrangling capabilities similar to Excel's Power Query. It also lets you create interactive visualizations, reports and dashboards with a few clicks or drag-and-drops; type natural-language questions about your data on a dashboard; and handle files that are too large for Excel.

It can work with dozens of data types -- not only Excel, Access and CSV files, but also Salesforce, Google Analytics, MailChimp, GitHub, QuickBooks Online and dozens of others. And, it will run R scripts -- meaning that any data you can pull in and massage via R you can import into Power BI.

Want to get more out of Excel? At Microsoft's inaugural Data Insights Summit last month, several experts offered a slew of suggestions for getting the most out of Excel 2016. Here are 10 of the best.

(Note: Keyboard shortcuts will work for the 2016 versions of Excel, including Mac; those were the versions tested. And many of the query options in Excel 2016's data tab come from the Power Query add-in for Excel 2010 and 2013. So if you've got Power Query on an earlier version of Excel on Windows, a lot of these tips will work for you as well, although they may not work on Excel for Mac.)

1. Use a shortcut to create a table. Tables are among the most useful features in Excel for data that is in contiguous columns and rows. Tables make it easier to sort, filter and visualize, as well as add new rows that maintain the same formatting as the rows above them. In addition, if you make charts from your data, using a table means the chart will automatically update if you add new rows.

When the U.S. begins accepting applications for new H-1B skilled-worker visas today, we can be certain that tech workers from India will make up a large portion of the requests.

What we probably won't know, though, is how many of those applicants are female.

While program data shows which job categories, countries and companies are awarded the most visas, the federal government says it is not tracking applicants' gender -- although the question is asked on the visa application form. The U.S. begins accepting H-1B visa applications on April 1 for the fiscal year that begins Oct. 1.

Analyzing 200,000 records may not seem like a big task. But when those records are security incidents with potentially hundreds of attributes each -- types of bad actors, assets affected, category of organization and more -- it starts getting a little complex for a spreadsheet. So Verizon's annual security report, which was initially done in Excel, is now generated "soup to nuts" in R.

In fact, the Verizon Data Breach Report is somewhat of "a love letter to R," Bob Rudis, managing principal and senior data scientist at Verizon Enterprise Solutions, told the EARL (Effective Applications of the R Language) Boston conference earlier today.
