Tumblr continuing on a downward slope

Tumblr is a micro-blogging web platform that lets users share all sorts of text, images, and videos. Although many of its users gravitate towards sharing content about fictional works, Tumblr blogs can be about anything the user chooses. In June 2013, Yahoo bought Tumblr for approximately $1.1 billion. Ever since the purchase, users have noticed some negative changes to website.

One simple change has been the oversimplification of the site’s design. Instead of keeping your blog statistics, such as how many followers you have and how many blogs you follow, off to the left of the page, they are now pushed into a floating header bar, along with messages, options, and notifications. Even if this change is small, it is still inconvenient.

The most annoying addition to the website is the introduction of advertisements. The sponsored posts on Tumblr are more active than ever and they are completely unwarranted. Originally, there were just recommended blogs near the top of the website. But currently, as you scroll down the dashboard, these dumb-looking frames containing ads keep popping up. I joined Tumblr because I had the freedom to pick and choose which content I wanted to see, but now that freedom has been taken away.

Another bothersome aspect is the fact that there are plenty of other problems the Tumblr staff could be working on. Users have constantly and actively voiced their opinions about issues such as: fixing the video player, implementing an effective chatting system, or allowing for more access control settings for private blogs. However, these cries have gone unheard as the staff continues to make updates that go against the wishes of the community and decrease the usefulness and enjoyment of the site.


Tumblr plays an important part in many users’ lives. Millions of teenagers use the website to discuss their interests and make friends through previously nontraditional methods. Countless others use it to discuss serious issues plaguing our society, such as gender or racial issues. The degradation of the site only grows the frustration of these users who may not have a place to shares their ideas and values. If the site continues down this path, its popularity may wane and another site may be able to take its place. Although I doubt this will happen anytime soon, it is still a possibility if Tumblr keeps disappointing its users.

Sony Brings Game Streaming to PS3

            Video game companies like Nintendo, Sony, and Microsoft often find themselves asking “How will we sell our games and consoles that are for out-of-date models once our newest product is released”. Well Sony is about to take a stab at this issue with its PlayStation 3. Now that PlayStation 4 has been on the market for a while, sales have significantly slowed for older games available on the PlayStation 3 as gamers are upgrading their systems rather than buying older games. Sony’s solution to this problem is to make a large list of around 100 PlayStation 3 games stream over their PlayStation Network. This allows people who own a PlayStation 3 to access any of these titles without a disk for $19.99 a month (similar to having Game Fly, but specifically for your system and with a better selection available). This not only attracts the PlayStation 3 consumers due to convenience, but also enables them to save countless dollars on games. Sony is using a bold strategy in doing this as they are selling the use of these games at a heavy discount in hopes that it will boost activity of sales significantly enough that they still make a large profit margin.


This online game streaming introduced by Sony will however offer them little risk as it significantly reduces their cost of producing physical games and cases. Uploading the games to the PlayStation 3 Network will take some initial capital, but much less than the amount it would cost to produce so many games that they offer that they may or may not sell in video game stores. It is definitely a wise decision to install this sales strategy as sales of all goods recently has been shifting toward more online-based and lacking sales in person at stores so this should benefit their game sales. When sales of an older system are slacking, it makes a lot of sense to me to accommodate the consumer and make the product more readily available. This PlayStation 3 video game gallery will become available on May 12th and I suspect sales will be pretty high. To attract potential customers Sony is offering a 7-day free trial to any PlayStation 3 owners who have not yet signed up for the service. I presume most if not all customers who use the free trial will purchase at least one month of the game streaming service for $19.99. They also will be offering the newer games for PlayStation 3 at a one-time extra cost. This essentially is the same thing as buying these games at the store, but makes it available digitally and without the hassle of the CD. Sony is the first video game company to attempt this strategy so it will be interesting to see how it works out for them. I would not be surprised if both Microsoft and Nintendo make an effort to offer a similar online gaming service as they always try to keep their consoles on a level playing field.

Leakers, motivations and consequences

We may have discussed this in class but I wanted to point out something about the differences in US government leaks. There are three major leaks that we can look at: Snowden's NSA documents, Julian Assange's wikileaks and the military documents leaked by Bradley/Chelsea Manning. (Future notice, I'm just going to refer to Bradley/Chelsea as Manning for convenience)

The idea of this blog post is to try to figure out the motives, goals and ideas that these leakers want to accomplish. In my mind Snowden and Manning are very similar in their intent. They are on the inside of their program and see what harm or injustices they are committing. Snowden was a system administrator, which means that he had a much larger amount of access than a typical NSA agent. After watching the documentary "Citizen Four" that had the initial interviews with Snowden when he was running from the United States, I believe I have a better idea of what his motivations were. His access allowed him to see all of the massive programs that the NSA was using to gather mass surveillance. In my mind, his motives were along the lines of, 'The people have the right to know what this government agency is doing and what they are collecting.' Different than most leaks, Snowden went directly through a specific set of journalists. Other leaks post everything at once, while his is pieced together and given context by a journalist.

Manning is similar to Snowden on the motivation part without a doubt. After leaking her documents, called the Iraq and Afghanistan war logs she writes, "This is one of the most significant documents of our time removing the fog of war and revealing the true nature of 21st century asymmetric warfare." Manning leaked a couple of videos of soldiers in Iraq and Afghanistan firing on targets without proper identification that they were targets. These leaks were carefully selected and trimmed of identifying information. She saw the injustices that the US military was committing and like Snowden, felt that the public should hear what is happening. Unlike Snowden, Manning leaked her information through Wikileaks.

Finally there is Assange, who had created and set up wikileaks. He is completely different than the previous two characters. His role is the stateless anarchist born in the internet age. Any leak he receives, he will post. When the documents detailing how the US government talks, deals with, and feels about certain other countries was leaked I think it showed his truer motives. He was just being an anarchist and hurting these countries how ever he could. It didnt matter to him about the actual content but how much this would sour relations or hurt a country.

And for a final point I think that it is important to note what happened to every single leaker. Regardless if they leaked because of moral conviction, these leakers were all discredited, attacked on personal basis, or made more important than their documents. Examples of this are Bradley/Chelsea Manning's gender identity issues, Julian Assange being charged and extradited for rape and Snowden being labelled as a traitor or a Russian spy.

This may be a simplistic view, but it seems that regardless of your motive or how you leak information about how the US government runs, every single possible card will be used against you. And the more painful thing is that the public will care more about the story of the leak over the actual leaked data. These should all be lessons to those who make the choice to leak any information from now on.

Small Robots, Big Strength

In one of the CNN articles that I examined entitled "These tiny robots have superhuman strength," microrobots approximately the size of a Matchbox car have the ability to pull 2,000 times their weight.  These robots, which are being developed by engineers David Christensen and Elliot Hawkes at Stanford University, have been able to pull weights, drag full cups of coffee, and pull objects up a wall in a lab setting.  Right now, there are two sizes in development.

Several real-world applications for the robots include equipping them with CO2 sensors and sending them into a devastated area or burning building to find survivors.  The small size of these robots also allows them to be sent to place objects in tough-to-reach spots like rafters of a factory, making them applicable in many office and production settings.

Since each robot costs only about $20, Christensen explains that it's not a big deal if one goes missing or gets lost in action.  Each robot can be made in under two days in a lab using 3D printers to make the parts.  Their design is heavily inspired by geckos and ants, "whose feet adapt when they climb or carry a load."  The 'feet' of the robot have spikes that stick to the ground.

The robots can haul an object by planting itself on a hard surface and then pulling a string attached to the object in question.  It repeats this process until the object reaches its destination (provided that there is nothing in the way)

Right now, the robots have only been in development for a few months and will appear at several robotics conferences in the near future.

The engineers hope that the robots can, after being fully developed, work just like an ant colony and accomplish tasks as a team.

My initial thoughts when reading this were if the robots were developed and redesigned in a way that allowed them to climb over obstacles (much like a real ant), they would be much more useful.  Their small size allows them to be ideal for situations in which humans are too big or are unable to reach, and it would be easy to attach a camera or other sensors and open up possibilities for many more uses.  Of course, there will be issues that present themselves such as privacy issues for attaching a camera to something so small and having it have the potential to be very hard to detect.  The engineers did not mention if this would be a product that would be available to the general public, but it would certainly bring about new challenges.

The article definitely does its best to glamorize the technology, and the robots themselves are not all that impressive yet, but what I found most interesting was the engineers' idea to use these tiny robots as a whole unit and colony as opposed to a singular device.  I feel like a lot of robots are expected to perform all functions on their own, and the idea of using many of these tiny little robots to accomplish a goal is interesting.  I also like the idea that we're taking a cue from something that works so well in nature and adapting it. I would be interesting to see how long full development takes on this project.

Fighting Fire With Bass

          Viet Tran and Seth Robertson, two engineering students from George Mason University invented a device that puts out fire with nothing but sound waves.  It is a speaker the size of a subwoofer a little bigger than a regular fire extinguisher, and plays a really loud bass for optimal sound waves.  At first, they thought this would be a failing project.  But it turns out that now they are trying to get their invention patented and turn it into something bigger.
           Regular fire extinguishers are full of chemicals, leaves powder and foam everywhere; and when putting out a fire with water, it leaves behind a big mess too while probably destroying the things that the fire didn't get to anyway.  This new way of putting out a fire can be greatly beneficial.  It will certainly leave less of a mess.  It leaves any harsh mad made chemicals out of the picture.  This can be put over stove tops to put out kitchen and grease fires.  They even think astronauts could deploy them, since the extinguisher contents would spread all over in space.  Sound waves can still be directed without gravity, so there is a great possibility that it could work.  All of this was a senior design project, and I think this is something that can actually be helpful to our society in the future, unlike many other things being invented today.

Virtual Reality in Cinema

Cinema has allowed us to be transported back in time, explore unknown planets and even find out what our toys get up to when no one’s around. In recent years, technological innovation has meant cinemagoers can become even more immersed in the stories they see on screen. One development in particular is virtual reality (VR) and now, for the first time, film-makers have at their disposal a range of revolutionary VR tools to help craft their movies.
Marketers, broadcasters, engineers, artists and architects are already onto VR. But the question being contemplated by movie executives is whether the VR revolution will catch the imagination of the public – or will a future where we strap boxes to our faces in the cinema aisles be too embarrassing?
Cinema is a spectacle. It’s a social experience you simply can’t get at home. It’s why we pay a premium for it. While home entertainment systems have improved considerably in recent years, the cinema industry has also upped its game. It’s now common for film goers to enjoy advanced digital 3D and 4K projections, complete with surround sound. But today’s digitally-savvy consumers want more – as do the film-makers. This is where VR comes into play. We’re already seeing huge changes to consumer technology as a result of affordable VR headsets such as the Oculus Rift and the Samsung Gear VR. While originally designed for the gaming community, they represent a quantum shift in technology that’s already changing expectations and experiences of going to the cinema.
During the Sundance Film Festival, Oculus announced that they will be launching the Oculus Story Studio. They claim that they will be releasing their first VR movie, Lost. Also they hope to use this Studio to provide VR advice and expertise to those who are interested in hopes to make this technology accepted by the public. 
With creations like this, cinemas will inevitably need to respond. While the big Hollywood studios will still primarily decide what we get to watch, this technology will soon become to popular for them to ignore. Overall, we’re going to see some incredible, transformative technology incorporated into entertainment inside and outside the home and I can not wait to see the future of Virtual Reality, especially in cinema.

Ears, the new biometric security system?


            Privacy and smartphones typically go hand in hand in today’s world. We have all heard of unlocking your phone through fingerprint, voice, facial recognition, password, or a combination of any of those. Well Yahoo labs is experimenting with their new authentication system Bodyprint, which allows users to unlock their phones using their ear. Sounds crazy doesn’t it. Basically the way this works is that Bodyprint “turns a smartphone’s capacitive touchscreen into a biometric scanner.” Because phones are becoming so much bigger and have a much higher resolution, they are actually able to accomplish it. Don’t worry if your thinking why the ear, Yahoo Labs is actually working on allowing other body parts to act as your key on your mobile device.
            Yahoo labs states that although, “fingerprint scanners are a convenient way to secure handsets…they are pricey and often limited to high-end handsets.” But while touchscreens sometimes lack the resolution to capture all aspects of a fingerprint, it is still able to capture larger outlines of bigger body parts. Bodyprint plans to utilize five different body parts for their security system, which include the ear, fist, phalanges (knuckles), palm, and fingers. According to their team, “our evaluation with 12 participants, Bodyprint classified body parts with 99.98 percent accuracy and identifies users with 99.52 percent accuracy, with a false rejection rate of 26.82 percent accuracy to prevent false positives.” When Bodyprint scanned the ear, they were able to achieve a 99.8 percent authentication precision and this is with a rejection rate of 1 out of 13.
            Apparently using the ear as a biometric scanner is not a new concept at all and the idea has been around for a while. Something surprising is that ears are basically like fingerprints and are all unique from person to person. Although the data is quite positive, Bodyprint is still in the development phase of their project to and will begin to test on a wider scale soon. So my question to you, if you had the choice to use an ear print or fingerprint, which one would you use.
