Summer. Con: It’s hot. Pro: You have more time to read Popular Science. And maybe even some books too. Here are some literary recommendations from the PopSci staff.
Dune by Frank Herbert. Ask a room of science and tech people for a fun beach read, and their minds immediately go for the science fiction classic. Haven’t read it yet? Don’t be scared. Fear is the mind-killer. You’ll have plenty of time to read it during your time off. —At least half of the PopSci staff.
I don’t normally read non-fiction on vacation, but I would recommend The Man Who Caught The Storm to anyone looking for an exciting non-fiction read. Besides, who doesn’t want to read about storms, storm-chasers, inventions, and narrow escapes while relaxing on a sunny beach? —Mary Beth Griggs
I read Why We Sleep recently and I have literally never had a book influence my behavior faster or more effectively. Walker is a leading sleep researcher and clearly knows his stuff, but is also skilled at simplifying the information for people who aren’t experts in neuroscience without dumbing it down too much. He also cites all of the studies at the end of each chapter, which is heaven for anyone who likes delving into the science for themselves. —Sara Chodosh
Written by longtime exercise and sports-science columnist Alex Hutchinson, Endure explores the importance of endurance in sports, and in life. The ability to persist through pain is as much mental as it is physical and it plays a key role in every sport, but particularly in endurance ones like distance running. In Endure, Hutchinson investigates the physiology and psychology of endurance and questions if there are truly any limits to the mind and body. —Claire Maldarelli
At 960 pages, this meticulous study of Teddy Roosevelt’s relationship to nature is on the heftier side for a beach read. But Brinkley somehow makes every bird observation, buffalo hunt, and conservation fight sing. It’s not an uncomplicated or uncontroversial story, but it’s a rich one, connecting the individual actions of this larger-than-life president to the historical context he lived in—and the contemporary society he helped create. —Eleanor Cummins
Radioactive by Lauren Redniss is both beautiful and strange— full of obscure and fascinating facts about the Curies, like that Marie learned how to blow glass in order to get test tubes in the shapes that she needed and Pierre was killed by a horse-drawn cart. It’s a little big to bring to the beach, but would be fun if you read while camping in your backyard— the copy I have glows in the dark. –Lexi Krupp
Did I recommend House of Leaves last time? [Editor’s note: Nope!] If not, I want to recommend it this time because it’s a book that’s impossible to read on an e-reader and it forces you away from technology, which is a dope hook for a beach book. —Stan Horaczek
The Ultimate Hitchhiker’s Guide to the Galaxy by Douglas Adams includes five novels in one book. I finished the first Hitchhiker’s book last summer on the beach. I can’t wait to jump into the second this year. Nothing better than digging your toes in the sand and visiting a Restaurant at the End of the Universe. –Billy ‘Don’t Panic’ Cadden

The best materials, sensors, and hardware to create a robot from scratch will also be covered, as well as how to build a variety of robots and the “brains” that power them.
Probabilistic Robotics (Intelligent Robotics and Autonomous Agents series) 1st Edition The Fourth Industrial RevolutionThe Fourth Industrial Revolution, according to author Klaus Schwab, is more significant and intricate than any previous industrial revolution.
These new industrial developments, which are characterised by a variety of cutting-edge new technologies (such as robotics and AI) fusing the physical, digital, and biological worlds, are having a profound impact on every sector of the economy and society, even raising the question of what it means to be a human.
Robot-Proof: Higher Education in the Age of Artificial IntelligenceMany industries will be automated in the future, therefore students today need to be ready for a job market where humans and robots will coexist. Author Joseph Aoun lays out the principles of a new discipline called humanics that will assist students in building on their inherent talents and equip them with data literacy to manage the flow of big data, technological literacy to comprehend how robots function, and human literacy—the humanities, communication, and design—all of which will help future professionals with opportunities for lifelong learning that will help them become more adaptable as automation progresses.

Modern Robotics Mechanics, Planning, and ControlHow To Make Google Assistant Read Your Articles Out Loud
Found an interesting article you’d like to read but too tired right now or busy doing something else? You could save it for later or ask your Google Assistant to read it to you instead. This way you won’t risk forgetting about it afterward.
The feature was recently introduced. Google explained that the technology is different from other screen-reading software, as it’s capable of reading text in a natural-sounding voice and cadence so that people won’t have trouble listening and understanding, even for longer periods of time.
Google’s virtual assistant is available on most Android phones, so if you’d like to hear it read out to you, all you need to do is follow a few simple steps.
Note: so far the feature is meant for listening to articles, blog posts, or short stories online.
Set Up the Voice Match on Your Device (If It’s Not on Yet)To check if your Google Assistant is already active and ready on your device, touch and hold its Home button or say “OK Google” or “Hey Google.” If nothing happens, it means you’ll need to manually turn on Voice Match on your device. Here’s how to do it:
1. Go to your device’s Settings app.
2. Scroll down until you find Google and tap on it.
4. Find and tap on the “Voice Match” feature under the Hey Google category.
5. Make sure the Google Assistant toggle is on. Also, turn on “Hey Google” under Voice Match.
6. Once Hey Google is on, Google will ask you to say a few phrases so that it can learn your voice. Follow the steps indicated.
Note: on some older devices that don’t offer the assistant’s services by default, you may have to download the Google Assistant app.
Get Google Assistant to Read Articles to YouBefore we start, we need to point out one thing. The feature only works if you’re using the Chrome browser on your Android device or any other Chromium-based browsing app. If you have one on your phone, you are good to go.
1. Open an article you’d like to read in your browser of choice, then simply say: “Hey Google, read it.”
2. The first time you’ll attempt this command, Google Assistant will probably say it can’t do that because “Screen Context” needs to be turned on first.
3. A pop-up window will promptly appear on the screen asking you to give the Google app access to use your screen context. Tap OK. You don’t have to go looking through Settings on your own.
4. Now go back to the article and ask the Assistant once again to “Read It.” This time it will surely oblige and say “Got it” or “OK.” It takes a few seconds, as the virtual helper scans the piece before starting to read it out loud.
Take Full Advantage of the ControlsYou can access these controls directly from the Notification tray as well. You can even close the browser and still be able to pause or play the reading just by swiping down from the home screen or directly from the lock screen.
But wait – there’s more. Can’t understand English all that well? Perhaps you would like to hear the virtual assistant read to you in your native tongue.
Look for the three-dot menu icon located in the upper-right corner of the “Read It” browser and tap it, then on Translation. Here you can choose the language you want the text translated to, including German, Spanish, Polish, Romanian, and more (42 languages in total). The feature leverages the power of Google Translate to achieve this, and the results are remarkably adequate and convincing.
From the same menu users can select a different voice to read their articles. You’ll find this option under “Read aloud voice.”
Additional ConsiderationsAs we mentioned above, you’ll need a Chromium-based browser for this feature to work. What’s more, “Read It” is not available for certain websites and most apps. (You’ll need to use the web version instead.) If you’ve stumbled upon a paywall or a log-in is requested to display the full article, the feature may not work. Despite these limitations, the new Google Assistant trick proves super useful. Going forward, Google will surely continue to improve it.
Want to get even more out of your Google Assistant? You may want to learn how to create an emergency routine using Google’s virtual helper, just to stay on the safe side of things.

Take A Beach Trip: Head To Ice (Innovation, Culture, Extreme)
Summer is arguably the best time of the year, and as we near the end of the season, it’s important that you book a trip to the beach (if you haven’t already done so or gone). Why’s that? Well, if you’re an entrepreneur, hitting the beach may actually help you to become more successful in the long-run. Living an entrepreneur life can often become a stressful life, and taking a beach trip can help reduce some of that stress and refuel your energy and creativity. This conference update is sponsored by the Peninsula Technology Incubator.
Consider going down to Virginia Beach, VA for ICE (Innovation, Culture, Extreme), a week-long celebration of innovation, culture, and extreme sports. Basically a kind of SXSW by the sea, ICE will feature several events and resources for entrepreneurs, as well performances from more than 30 national, regional, and local artists, including Breathe Carolina, Unwritten Law, FFU (featuring Bam Margera), Shwayze, and Arum Rae (featuring Steve West of Pavement). Additionally, ICE has partnered with Coastal Edge to feature skate demos with national and local celebrities.
At this year’s ICE, entrepreneurs will get an opportunity to pitch their ideas to local investors and hopefully come home with some funding for their startups. We’re also proud to hold our Southeastern Virginia edition of Tech.Co’s Startup of the Year Competition & Mixer at ICE (Innovation, Culture, Extreme).
Need more reasons to go? Here are the top 5 reasons why entrepreneurs need take a beach trip:
1. A Time to UnplugAs a startup founder, you’ll often find yourself hooked to a device for a majority of your days. Whether it’s on your laptop doing work or checking email on your phone, your desire to make your company succeed is tied to this notion of having to be plugged in 24/7 – but maybe this is a misguided belief. According to a study from the University of Gothenburg (Sweden), constant technology use has been linked to numerous mental health issues (like depression), higher levels of stress, and sleeping problems.
And if you want to escape the daily drudgery of emails, then the beach is where you need to go. According to a study, the brain becomes less stressed when looking at nature scenes; if you’re a startup founder in a big metro area, maybe consider making a trip to Virginia Beach and relaxing for a bit. In another study conducted by the University of Exeter (UK), those living near a beach were found to be in better health and well-being than others. So, maybe even considering just picking everything up and moving to the beach?
2. Get Some Sun TimeFor many entrepreneurs, the days and nights are spent indoors. Going to the beach gives you an opportunity to leave your gave and get some actual time in the sun. But it’s not simply about getting a tan when you lay out at the beach, it’s also about getting your dose of much-needed vitamin D.
According to findings from Harvard Medical School, the largest source of vitamin D is not through daily supplements, but through sun exposure to our very own skin. This vitamin D is not only a necessity for bone and skin health, but may also have the potential to improve our mental health. In the startup world, where success is glamorously lauded, anything that can help boost the state of your mental health is surely welcoming.
3. Benefits of Being Near WaterDid you know that we’re actually happier when near bodies of water? According to a 2011 study that tracked the well-being of approximately 22,000 participants, people were found to be 5.2 percent happier just by merely being near bodies of water. And if you’re into swimming, the activity has actually been found to contribute to decreased stress, anxiety, and levels of depression – all things that many entrepreneurs experience in their day-to-day.
4. Sensory StimulationVarious studies have found that a stimulation of all our senses can contribute to the creative process. The sound of the waves, the smells from various boardwalk vendors, the taste of the salty air, the feel of the sand beneath your feet, and the view of the setting sun – the beach is replete with things that could help kickstart your creativity. Oftentimes, whether a company thrives depends on whether it was able to successfully find a creative way to solve a problem.
5. Social InteractionHumans are innately social creatures – going too long without interacting with another human can have a significant impact on our personal health. For some entrepreneurs who are just starting out, there’s a chance that you’re working simply by yourself. The beach is probably one of the best places to meet new people and socialize. You never now – maybe you’ll talk to someone who’ll want to support your company in some way.
Play a pick-up frisbee game with the beachmates to your left, hit up the ICE block party, or mingle with other investors and entrepreneurs at ICE and Dice (over games of Texas Hold ‘em, Blackjack, Craps, or Roulette, of course).

How To Open A File Just To Read In Python?
In Python, file handling involves many operations; among them, one such task is opening a file for reading and this makes it possible for you to access and retrieve data from the file. In this article, we will discuss and learn how to open a file in read mode using Python; we will use some code examples with self-explanatory descriptions to help you understand and master the process of reading files in Python.
Opening a File for Reading and Printing its ContentFor a file to be opened for reading and printing its content, you can follow these steps:
Step 1: You make use of the open() function to open the file. Then you provide the file path as the first argument and use the mode ‘r’ to indicate read mode.
Step 2: You then assign the returned file object to a variable for further operations, such as reading the file content.
Step 3: You also use the read() method to read the content of the file and store it in a variable.
Step 4: You then print the content of the file using the print() function or perform any necessary operations on the content.
Step 5: At last, you can close the file to ensure proper handling of system resources.
ExampleSuppose we have a text file as shown below
#myfile.txt This is a test file # Open the file for reading file = open('myfile.txt', 'r') # Read the content of the file content = file.read() # Print the content print(content) # Close the file file.close()When we run the above code we get the following output when the chúng tôi is opened and existing content is read.
Output #myfile.txt This is a test file Opening a File for Reading Line by LineIn order to read a file line by line, follow these steps:
Step 1: You make use the open() function to open the file in read mode.
Step 2: You can then assign the returned file object to a variable.
Step 3: You opt for using a loop to iterate over each line in the file.
Step 4: Each line within the loop (e.g., print it or perform other operations) can be processed.
Step 5: Lastly, you can close the file to release system resources.
ExampleSuppose we have a text file as shown below
#myfile.txt This is a test file. This is the first line. This is the second line. This is the third line. # Open the file for reading file = open('myfile.txt', 'r') # Read the file line by line for line in file: # Process each line (e.g., print it) print(line) # Close the file file.close()When we run the above code we get the following output when the chúng tôi is opened and existing content is read.
Output #myfile.txt This is a test file. This is the first line. This is the second line. This is the third line. Using Context Managers to Read a FileYou must know that a context manager in Python is an object that gives a description of the runtime context that will be created when a code block is executed using the ‘with’ expression. It makes available a method for allocating and releasing resources at exactly the proper time. The ‘with’ statement, for example, can be used to open a file in Python and close it once you’re done working with it.
Python in this way makes it easy to read files using context managers. Context managers, as you have now learned, help automate file closing, even if an exception or error occurs. This is how you can make use of a context manager to read a file:
Step 1: You can make use the ‘with’ statement and the open() function to open the file in read mode.
Step 2: You can then assign the returned file object to a variable within the with block.
Step 3: You, lastly, process the file content within the with block (e.g., print it or perform other operations).
ExampleSuppose we have a text file as shown below
#myfile.txt This is a test file # Open the file for reading using a context manager with open('myfile.txt', 'r') as file: # Process the file content (e.g., print it) content = file.read() print(content)When we run the above code we get the following output when the chúng tôi is opened and existing content is read.
Output #myfile.txt This is a test file Reading a File and Counting the Number of LinesTo be able to read a file and count the number of lines it contains, you can follow these steps:
Step 1: You use the open() function to open the file in read mode.
Step 2: You then allot or assign the returned file object to a variable.
Step 3: You then go on to initialize a counter variable to keep track of the number of lines.
Step 4: You can make use of a loop to iterate over each line in the file.
Step 5: You can go on to increment the counter variable by 1 for each line.
Step 6: Lastly, you can close the file to release system resources.
ExampleSuppose we have a text file as shown below
#myfile.txt This is a test file. This is the first line. This is the second line. # Open the file for reading file = open('myfile.txt', 'r') # Initialize the counter variable line_count = 0 # Read the file line by line and count the lines for line in file: line_count += 1 # Print the line count print("Number of lines:", line_count) # Close the file file.close()When we run the above code we get the following output when the chúng tôi is opened and existing content is read and number of lines counted we get the following output.
Output Number of lines: 4 Reading a File and Extracting Specific InformationTo be able to read a file and extract particular information from it, you make use of the following steps:
Step 1: You use the open() function to open the file in read mode.
Step 2: You assign the returned file object to a variable.
Step 3: You then read the file content into a variable using the readlines() method, that returns a list of lines.
Step 4: You next process the content of the file to extract the required information. You use string manipulation techniques, regular expressions, or other methods based on your particular requirements.
Step 5: At the very end, you can close the file to ensure proper handling of system resources.
ExampleSuppose we have a text file as shown below
#myfile.txt This is a test file. This is the first line. This is the second line. # Open the file for reading file = open('myfile.txt', 'r') # Read the file content into a list of lines lines = file.readlines() # Extract specific information from the file content for line in lines: if 'test' in line: print(line) # Close the file file.close()When we run the above code we get the following output when the chúng tôi is opened and existing content is read and the line containing the word ‘test’ is extracted and printed as the following output.
Output This is a test file.Opening a file for reading is a basic or fundamental operation in domain of Python file handling. In this article, we seen and discussed some examples that gave a demonstration how to open a file for reading and retrieve its content. We also provisioned additional code examples that demonstrated reading a file and counting the number of lines, as well as reading a file and extracting specific information. By following and applying the systematic explanations and code examples, you can gain a sound understanding of the concept of reading files in Python. It is to be remembered to close the file after reading without fail so as to ensure proper handling of system resources.
