Raspberry Pi WiFi 2.4/5GHz Solution

I use a Raspberry Pi as a WiFi Bridge to allow me to login to XFinity WiFi which is closer to my garage than my WiFi router (which is also XFinity – benefits of being a customer). Then all of a sudden I noticed that I had difficulty accessing a network. It appeared that I could not access a 2.4GHz band, just the 5GHz band and that stumped me.

What I found solved my problem is modifying the /etc/wpa_supplicant/wpa_supplicant.conf file to include all the frequencies on both channels and POOF problem solved.

freq_list=2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472 5170 5180 5190 5200 5210 5220 5230 5240 5260 5280 5300 5320 5500 5520 5540 5560 5580 5600 5620 5640 5660 5680 5700“

I also added a neighbors WiFi who kindly allowed me access to facilitate my Zwift training sessions especially in the winter. Fun challenge.

Developer Survey Results 2018

https://insights.stackoverflow.com/survey/2018/

This year, over 100,000 developers told us how they learn, build their careers, which tools they’re using, and what they want in a job.

Each year, we ask the developer community about everything from their favorite technologies to their job preferences. This year marks the eighth year we’ve published our Annual Developer Survey results—with the largest number of respondents yet. Over 100,000 developers took the 30-minute survey this past January.

This year, we covered a few new topics ranging from artificial intelligence to ethics in coding. Here are a few of the top takeaways from this year’s results:

  • DevOps and machine learning are important trends in the software industry today. Languages and frameworks associated with these kinds of works are on the rise, and developers working in these areas command the highest salaries.
  • Only tiny fractions of developers say that they would write unethical code or that they have no obligation to consider the ethical implications of code, but beyond that, respondents see a lot of ethical gray. Developers are not sure how they would report ethical problems, and have differing ideas about who ultimately is responsible for unethical code.
  • Developers are overall optimistic about the possibilities that artificial intelligence offers, but are not in agreement about what the dangers of AI are.
  • Python has risen in the ranks of programming languages on our survey, surpassing C# in popularity this year, much like it surpassed PHP last year.
  • When assessing a prospective job, different kinds of developers apply different sets of priorities. Women say their highest priorities are company culture and opportunities for professional development, while men say their highest priorities are compensation and working with specific technologies.

Want to dive into the results yourself? In a few weeks, we’ll make the anonymized results of the survey available for download under the Open Database License (ODbL). We look forward to seeing what you find!
