How to Test Your Internet Speed with a Terminal Command


You probably know about the internet speed tests that can be performed from your browser. However, Make Tech Easier shows us that you can do the same thing right from a terminal window—perfect for your Raspberry Pi or home server. Just open a terminal and run the following command: wget -O /dev/null http://speedtest.wdc01.softlayer.com/downloads/test10.zip The test basically downloads a 10MB file using the wget command to pull a file from a remote server. The speed is displayed in the terminal when the file download has completed, so you know how fast your connection is running. Any Linux PC can perform the wget command out of the box. Windows and Mac users will need to download the program, but it still functions more or less the same. Hit the link to read more.

Are Early Upgrade Plans Worth It?


Sprint finally crossed the finish line and now all four major carriers have an early upgrade plan in place. Are they better than just buying phones outright though? Well, maybe. For the uninitiated, here's how it works: each of the four major carriers now offer a plan that allows users to upgrade before their two year contract is up. T-Mobile Jump, AT&T Next, Verizon Edge, and Sprint One Up offer variations of the same idea. You pay a monthly fee based on the full cost of your phone separate from the cost of service and, once your phone is paid off, you can leave the carrier. However, you can also trade in your phone at regular intervals (six months for Verizon and T-Mobile, yearly for AT&T and Sprint) to get a new one. Sounds neat. Whether they're worthwhile is a complex question, though. The Early Elimination Round If you're looking to save as much money as possible, none of these plans are really that beneficial to you. For that, we'd suggest following this guide to buying your phones off contract and selling them for as much of their value as possible. That being said, there are some people that might benefit from early upgrade plans on certain carriers. There are two basic criteria that anyone interested in these plans must meet: You know for sure that you want to stay with your current carrier for more than two years. You will probably never try to sell your old phones. We're already used to locking into carriers for the long haul, but by offering phone renewals mid-term, all four carriers effectively lock you in indefinitely. Either you stop upgrading and wait out the rest of your monthly payments, or you bite the bullet and pay off the rest of your phone which could be even more expensive than your typical ETF. The Breakdown If you're still here, you probably want to know just how much extra it's going to cost you to upgrade to the latest and greatest. To that end, here's a handy chart to compare the various plans. For reference, we looked at the cost of an HTC One on all four carriers and comparable individual plans.
As you can see, no matter which plan you go with, you'll be paying a premium for those new phones. However, some carriers are better than others. Here's how each one measures up: Should I Use It? Verizon Edge: Almost certainly not. Almost. If you only use Verizon Edge to upgrade once per year, you're spending the exact same amount as you would if you got a regular two year contract and bought a $600 phone off-contract halfway through your term. There's no reason to do this unless you're completely confident you want to stay with Verizon and you're bad at saving money. If you're planning on upgrading every six months, you'll spend $1200 more than a normal contract. This is, technically, less than you would spend buying a new phone every six months while on a regular contract. If having the latest phone is worth $1200 to you, then maybe you could consider this, but keep in mind that you have to pay off 50% of each handset every six months. This will raise your monthly payment to obscene levels. You're really just better off selling your old phones. AT&T Next: No. That's it. There is no situation in which AT&T Next can be viewed as anything but a huge rip off. AT&T only spreads monthly payments out over 20 months instead of 24. Because of this, you're actually paying more than half of the phone's cost every year. If you never upgrade, you'll pay exactly the same amount as you would if you bought your handset off contract (on top of your regular service that normally includes a subsidized phone). However, if you upgrade after one year, you'll end up paying more in handset payments by the end of two years than either phone is actually worth. Keep in mind, if you didn't use AT&T Next, you'd get one phone on contract. You could then buy a second phone with the money you'd save and still have some leftover. Don't do this. AT&T Next is universally bad. T-Mobile Jump: T-Mobile is in a special category because the carrier's Jump plans include handset protection. Normally, this costs $8/month so if you're already buying that, you may as well spend the extra $2/month to get on board Jump. Additionally, T-Mobile makes you pay for your handset separately no matter what plan you choose. From this perspective, Jump is an okay deal. Upgrading every six months will only cost about $540 more than you'd spend on a single phone in two years if you don't buy handset protection, and $348 more if you do get the protection. While you might be able to save that by selling phones, the convenience alone could make it worth it to you. Sprint One Up:While it only affects a very small category of people, Sprint's One Up plan is the only one on this list that can actually save you money. Sprint offers a $15 discount on its service if you use One Up, since you're not getting a subsidized phone. Because of this, it's only $276 more expensive to upgrade after one year. That $276 isn't enough to buy a second phone with on a regular contract plan, and selling your first phone might not even make up the difference, depending on the handset or its condition. Even buying out your One Up plan after two years is slightly cheaper than buying a second phone for full price on a regular contract (again, assuming you never sell your phones). Ultimately, whether these plans are worth it is up to your particular situation. Verizon and AT&T both offer extremely expensive plans that aren't really worthwhile even to the tech enthusiasts that always want the latest and greatest. Sprint and T-Mobile, though, offer an interesting proposition. Is having the newest phone worth $200-500 over the course of two years to you? If so (and you meet the two criteria mentioned earlier), then Jump or One Up may be something to look into.

Freeze and Use Squeezed Out Lemons to Keep Other Foods Fresh


Once you've squeezed all the juice out of a lemon, resist the urge to toss it out or down the garbage disposal (although that'll keep it fresh too). Instead, toss them in the freezer, and when you need to keep other foods fresh and bright, you'll already have a little acid water on hand for the job. We've already explained how useful acidulated water can be—just a little keeps apples, potatoes, artichokes, and other fruits and veggies bright and fresh. If you don't want to keep a container of acid water in the fridge all the time, keep a baggie of spent lemons in the freezer. That way when you need acidulated water, you can grab one of them out of the baggie, soak it in water, and add what you need to keep fresh then—there's still enough acid in that lemon to get the job done. Alternatively, we've also shown you how a little honey water can do the same thing, thanks to the wonder of chemistry. Whatever method you prefer, you'll never have to deal with browned apples or pears ever again.

Nice Weather Is a Free, Minimalist Weather App for Android


Android: If you're a fan of the flat, minimalist aesthetic that seems to be all the rage these days, Nice Weather delivers. Simple icons for the current weather conditions, a line graph for temperature over time, and a single color to give you an instant idea of the forecast. It's simple and sharp with no added fluff. Even if you're not a fan of minimal app design, Nice Weather is still worth a look. The color of the background gives you an instant read of what the forecast will be. There are two graphs at the bottom of the screen: the line graph shows you the temperature forecast for the whole day (with a dot to show you where you are now on the progression), and a second faded graph behind it shows you the chance of precipitation for the day and when it's the highest. A single icon for current conditions is center stage, right above the chance of precip overall, temperature, and wind speed. The app updates itself automatically (so you don't have to refresh), a swipe brings up the forecast for the next five days, and the app keeps your forecast cached so you can access it offline. Nice Weather is completely free, and available now at Google Play.

How Your Memory Works (and Three Ways to Improve It)


How would you like to be able to recall the name of a client or associate you just met? How would you like to go to the bank and not fumble for your account number every stinking time? Everyday scenarios like these are classic examples of our need for memorization. The function of memory has so many more applications, too—public speaking, schoolwork, studying, research, the list goes on and on. Imagine if we could be better at it. Would you believe that memorization is not an innate ability but rather a learned skill? Approaching the topic from this paradigm changes everything. You can learn how to memorize. You can become a memory expert by application and sheer force. You have the power to memorize anything and everything.

How Our Brain Memorizes Things


Before we get to the memorization techniques, first a science lesson on how the brain stores memories. You likely know that the brain is a complicated, beautiful system of working parts. Two of those working parts—the neurons and the synapses—are flexed during the memory-creating process. Neurons are the parts of the brain that send and receive electrical signals. Synapses are the roads that connect them. When memories are recalled, a series of neurons sends signals throughout the brain, creating a sequence that represents the memory. This pathway has been tested by scientists who can send electrical shocks into the brain, masquerading as these initial neuron signals, that can initiate a memory sequence. The stronger the synapse, the greater chance that a memory can be recalled. Consistent use of synapses often creates stronger connections, similar to exercising. So, say, recalling your old apartment number or childhood home phone is easier than a bank account number because an address or phone gets used more often. Weak signals—i.e., bank-account signals—lack the ability to create the cascade of neurons essential to initiating a memory. The Problem with Memory Today One of the leading voices on memorization is Joshua Foer, a journalist by trade who trained himself in one year’s time to become a memorization national champion (Foer’s exploits are documented in the book Moonwalking with Einstein). His perspective on the topic of memory points to an interesting, 21st century problem: Externalizing vs. Internalizing. Technologies (iPhones, software, etc.) have made our modern world possible, but they’ve also changed us. They’ve changed us culturally, and I would argue that they’ve changed us cognitively. Having little need to remember anymore, it sometimes seems as if we’ve forgotten how. With so many apps and tools at our disposal, memorization has transferred from a purely mental exercise to a tangibly outward endeavor. (Foer is not quite the first to share this sentiment. Socrates was sour on writing because he feared it would weaken memory.)

Three Techniques to Become a Better Memorizer


Construct a Memory Palace The ancient Greeks and Romans did not have the luxury of an iPhone or Evernote. When their scholars and orators remembered something, they did so the old-fashioned way: mentally. The common technique of the time was a Memory Palace, also known as the “method of loci,” also known as “mental mapping.” The technique works like this: Visualize a familiar space in your life, i.e. your house or your workplace. Find five rooms or areas in this space. Choose five large items in each room to serve as “files” for your memorizing. Assign each of these five large items a number, beginning with one and going room to room in ascending order. For instance, in your office, your desk may be 1, your office chair 2, your bookcase 3, your whiteboard 4, and your door 5. In the break room, begin with the break room table at 6, the sink as 7, etc., etc. Number as many items in as many rooms as you wish, and keep in mind that you can always add more items and rooms later. It is helpful to number the items in an orderly way as they flow in the room.
At this point, your Palace is constructed. Now, let’s fill it. Picture what it is you want to remember. Associate this memory with an item in a room. Let’s say you want to commit to memory each of the 12 teams in the Pac-12 football conference (to impress your boss, a Cal grad). Based on the above Memory Palace that I constructed in the workplace, the list might look something like this: A wildcat is chewing on my desk (Arizona) The devil is napping on my office chair (Arizona State) The giant bear is pawing at Malcolm Gladwell’s Blink in my bookcase (Cal) A buffalo is drawing caricatures of me on my whiteboard (Colorado) A duck is laying eggs on my door jamb (Oregon) A beaver is chewing off the legs of the break-room table (Oregon State) Someone stuffed a tree down the garbage disposal in the sink (Stanford) … (and so on and so forth for UCLA, USC, Utah, Washington, and Washington State)
The visualization is important. The more vivid these scenes appear in your imagination, the more likely it is that you will recall them. Joshua Foer, the memorization champion, found that visceral, lewd, or bizarre imagery often worked best. This is called the Von Restorff effect. Create a Peg System An ideal technique for memorizing lists, similar to the scientific method of saying “no,” the peg system functions in a similar way to the memory palace: Create an association between what you want to memorize and what your mind already knows. To use the peg system, you assign words to a list of numbers, creating a mental image for each “peg.” Then, you can attach what you wish to memorize to these pre-memorized pegs, creating a vivid connection in your mind. The initial pegs can be created with anything. Common starting points are words that rhyme with each number or shape corresponding to the shape of each number. Here’s a rhyming example for one through ten: 1 = sun 2 = shoe 3 = bee 4 = spore 5 = jive 6 = ticks 7 = heaven 8 = grate 9 = wine 10 = hen Once you commit your pegs to memory, then you can begin associating your to-be-memorized lists. Let’s say, for instance, that you need to memorize a shopping list. Your list might look like this: Bananas: A banana-shaped sun Toothpaste: A shoe full of toothpaste Birthday card for mom: A bee writing a sweet message in a greeting card Memorize Verbatim Text The above techniques work great for memorizing individual items. But what if you have a chunk of text you want to commit to memory? You can try a Memory Palace of paragraphs or a Peg System of key points, but here’s an even better option: the first-letter text method. The method is not a visual one, like the methods listed above. The key to the first-letter text method is good, old-fashioned hard work: Practice recalling, not repeating: This is the crucial concept of any type of memorization. The act of reading something you want to memorize fires different connections than the act of recalling. This is how you learn to memorize–your practice recalling, not repeating. Recalling vs. repeating might sound like semantics, but the distinction is notable. If you want to memorize a large chunk of text, you are better off recalling it within your mind than reading it over and over on paper. This is how the first-letter method functions. Take the first letter from each word in your chosen text. This becomes your study guide. Let’s use a couple paragraphs from Martin Luther King’s “I Have a Dream” speech as an example. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight; “and the glory of the Lord shall be revealed and all flesh shall see it together.” And here’s what it looks like with the first-letter text method (Productivity501 has a helpful tool on their website). I h a d t m f l c w o d l i a n w t w n b j b t c o t s b b t c o t c. I h a d t o d e v s b e, a e h a m s b m l, t r p w b m p, a t c p w b m s; “a t g o t L s b r a a f s s i t.” Now, instead of reading the text verbatim, you are recalling the text. Your brain is exercising its synapses in a way that will lead to better memorization. Reading through those first letters, you may find yourself recalling bits and pieces from the full text. Good. Great! The more practice, the easier it gets. Other Notable Methods Psychology research has gone into the theory of mood memory: If you want to remember something, get back to the mood you were in when you experienced it. The Link System works in a similar way to the Peg System, albeit without the numerical order. Say you need to memorize a list of arbitrary terms—a dog, a cake, a house, the rain. With the link system, you visualize an interaction between each consecutive item, e.g. a dog eating a cake, a cake filling a house, a rainstorm of houses. Ron White, a former memorization national champion, has an intriguing method for recalling numbers. He assigns each friend a number, and he needs to memorize a new number, he simply pictures his friends in a particular order. Associating a name with a personality trait or visual cue is an effective method. The Office‘s Michael Scott took this to a famously insulting extreme. Ben Pridmore, a World Memory Champion, once memorized a deck of cards in 24 seconds. His Pridmore technique, documented here, is quite extensive. (Aside: What does it take to be a Grand Master of Memory? You must memorize the order of 10 decks of cards in 60 minutes, memorize 1,000 random digits in 60 minutes, and memorize the order of one deck of cards in less than two minutes.) What Works for You? Memorization—on a small scale in the work place or a large scale at the national championships—often comes back to the same foundation of visualizing, associating, and recalling. Some of the above methods might work wonders for you, or perhaps you have muddled together your own system that you swear by. I have been wanting to memorize a famous speech for some time, and I plan on giving the first-letter text method a go. How about you?
