Portability and the Effects on Device Internals

With the current trend of ever-shrinking tech devices, we have seen an explosion in the abundance of portable electronics. Fifteen years ago Apple launched the iPod, a device so foreign to people that Steve Jobs had to explain you could legally transfer your CD collection to your computer then onto your iPod. Now it is expected that the little (or big) phone in your pocket works as well as any desktop computer with fully developed applications and lasts a full day on one charge. There are many different advances that made this possible, such as the reduction in size of the fabrication nodes, increased battery storage, and much better video display options. But I think one change in design philosophy in particular has driven the current trend in tech.

Due to portability requirements phones have become a microcosm of the tech industry, specifically in the trend of increasing complexity at the cost of repairability. When the first iPhone came out there was no option to change battery or storage configuration, options both available on competitors’ devices. And yet people flocked in droves to Apple’s simpler, less-customizable devices, so much so that now Google produces its own phone, the Pixel, which has a non-removable battery and lacks a microSD slot. Logic dictates that there must be an outside pressure to force a competitor to drop a substantial differentiator from other products on the market; I would argue that factor is thinness.

The size of an SD card slot seems pretty inconsequential on a device the size of a desktop computer but when it takes up 1% of the total space of a device, there are arguments for much better uses of the space. A better cooling system, larger internal battery, or just space for a larger PCB are all uses for the extra space that may make the device better than it could have been with the SD card slot. When you look at the logic boards for the iPhone, this point is illustrated; there is just no space for any extra components.

Driven by space-saving concerns, complexity increases as smaller and smaller traces are used on the PCB and components have to shrink, shuffle or be removed. Proof of this is in the design of larger machines such as the Macbook, a 12-inch laptop with a logic board smaller than its touchpad, which features a mobile CPU and no removable storage.

  Demand for ultra-portability has led to devices that are so small that they are almost impossible to repair or upgrade. However, this trend cannot continue indefinitely. Moore’s law has taken a couple hits in the past couple years as Intel struggles to keep pace with it and PCB manufacturing can only get so small before it is impossible to fit all the components on it. As size becomes less of a differentiator and reaches its physical limits, tech companies will have to look to new innovations to stay relevant, such as increasing battery life or designing new functions for the devices.

How To Find Your Device’s MAC/Physical Address

The Physical address of a device is an unchanging number/letter combination which identifies your device on a network. It is also referred to as a Media Access Control Address (MAC Address). You may need it if you’re having issues with the campus network and UMass IT wants to see if the network itself is the problem.

To find the MAC/Physical address on a Windows 10 device:

Right click on the Start button to make a menu appear:


Select Command Prompt from the menu.

In the window that appears, type “ipconfig /all” without the quotes:


The resulting text displays information about the parts in your computer which communicate with the network. You’ll want to find the one that says “WLAN adapter” and look under that heading for the Physical Address:











To Find the MAC Address of a Apple/Macintosh computer:

Click the apple menu in the top left of the screen and click System Preferences:


In the window that appears, click “Network”:


Highlight WiFi on the left-hand side and click advanced:


Navigate to the Hardware tab to find your MAC address:


To Find the MAC address of an iPhone:

Use the Settings app, go to General>About and the MAC Address is listed as “WiFi Address”:


To find the MAC address of an Android device:

The location of the MAC address on an android device is unique to the device, but almost all versions will show it if you navigate to Settings>Wireless and Network; the MAC address will be listed on the same page or in the Advanced section:


You may also be able to find the MAC address in the “About Phone” section of the setting menu:

CyberGIS: Software

(Superbowl Twitter Map — CARTO)

What is CyberGIS (Cyber Geographical Information Science and Systems)? CyberGIS is a domain of geography that bridges computer science and geographic information science and technology (GIST). It is the development and utilization of software that integrates cyber infrastructure, GIS, and spatial analysis/ modeling capabilities. In this TechBytes article I will discuss two current and popular CyberGIS software for academic, industry, and government use.

CARTO: Unlock the potential of your location data. CARTO is the platform for turning location data into business outcomes.

CARTO Builder was created for users with no previous knowledge in coding or in extrapolating patterns in data. A simple user interface comprised of widgets allows the user to upload their data and instantly analyze a specific subset of the data (by category, by histogram, by formula, or by time series). From calculating clusters of points, detecting outliers and clusters, and predicting trends and volatility with the simple press of a button — CARTO Builder is truly made with efficiency and simplicity in mind. While CARTO builder “can be used in every industry, we are targeting financial services, to help them predict the risk of investments in specific areas, and telecom companies,” Javier de la Torre, CEO at CARTO.

 Mapbox: Build experiences for exploring the world. Add location into any application with our mapping, navigation, and location search SDKs. 

Unlike Carto, Mapbox was built for developers and cartography enthusiasts. While the graphical interface is easy to navigate (similar to photoshop or illustrator) Mapbox’s goal was to “create something equally useful for tech developers who have no idea how to design and designers who have no idea how to code” (Wired). While MapBox lacks the data analytics features of CARTO Builder, it makes up in its ability to manipulate a map any way the user likes. Based in both DC and San Francisco, Mapbox is partnered with large companies such as The Weather Channel, National Geographic, and CNN. Mapbox is optimized for navigation, search, and vector maps rendered in real time.

As a CyberGIS geographer myself, I use both CARTO Builder and Mapbox in my classes and in my research. When I have a dataset that needs to be geo-referenced on a map and not necessarily analyzed — Mapbox is my first choice. The ability to not only alter the color scheme to highlight the various features of the map, but to choose fonts and for labeling is something I take for granted. When using CARTO Builder those features are still present but are quite limited  — and when using ArcGIS online those features are non-existent. If an assignment requires more analysis on a given set of data, CARTO Builder is a simple way to parse data and run the specific algorithms.

Thinkpad turns 25 – A look at the Thinkpad 25th Anniversary Edition Ultrabook

Thinkpad is known throughout the enterprise and consumer markets as Lenovo’s rugged, minimalistic, and business-oriented laptops, tablets, and mobile workstations division. Started under International Business Machines (IBM) in 1992, Lenovo acquired the division in 2005 and has owned the company ever since.  For 25 years, Thinkpads have been beloved by power users, demanding businesses & corporate environments, enthusiasts and even astronauts on the International Space Station (ISS). Today we take a brief look at the Thinkpad 25 Anniversary Edition, and the features that have persisted through the years of one of the longest continual laptop series.

Looking at the Thinkpad 25, there appear to be more similarities with modern Thinkpad laptops than the older era of Thinkpads it is supposed to be reminiscent of. The Thinkpad 25 comes with ULV 15w 7th gen Intel Processors, NVMe storage, a 1080p display, Nvidia 940MX dedicated graphics, the beloved trackpoint, and the distinctive minimalist black matte finish. The Thinkpad 25 also comes with a separate box of documentation and items that look back upon the series’ history and development, 25 years of such.

The biggest difference in the Thinkpad 25 has to be the keyboard. The inclusion of a seven-row keyboard in the Thinkpad 25 when almost all modern computers are six row keyboards is nothing short an industry nod to when the seven-row keyboard reigned supreme. The Thinkpad 25 keyboard also has other references to earlier models, such as the blue enter key, dedicated page up and down keys, the delete “reference” key and traditional, non-island styled/chiclet keys. Omitted from the Thinkpad 25 are several antiquated technologies from over the years, such as the Thinklight, legacy ports (Serial, VGA, expresscard), and handle batteries.

To many enthusiasts, the Thinkpad 25 was a letdown; essentially a T470 with a seven-row backlit illuminated row keyboard.  The Thinkpad 25 is also expensive, at nearly $2,000 fully configured, and with such minimal specifications, many businesses will shy away from these devices. So, who is the Thinkpad 25 meant for then? This device was nothing but a limited-quantity device, for enthusiasts and collectors who yearn for a nostalgic legacy; for those who stubbornly resist modern design and technology implementations such as shiny plastic or brushed aluminum with a certain illuminated fruit. For those that have stood by the Thinkpad line through two and a half decades of cutting-edge innovation and performance, and are willing to pay the price for a computer that nods to this era of computing, then the Thinkpad 25 may be a worthwhile investment.

A Quick Look at Home Theatre PCs

Are you one of those people that loves watching movies or listening to music while at home? Do you wish you could access that media anywhere in your home without lugging your laptop around your house and messing with cables? If you answered yes to these questions, then a Home Theater PC, or HTPC, may be for you.

An HTPC is a small computer that you can permanently hook up to a TV or home theater system that allows you to store, manage, and use your media whether it is stored locally or streamed from a service like Netflix, Amazon, or Spotify. Although several retailers sell pre-built HTPCs that are optimized for performance at low power, many people use a Raspberry Pi computer because they are small, quiet and relatively inexpensive. These are key features because you don’t want a loud PC with large fans interrupting your media experience, and a large computer won’t fit comfortably in a living room bookshelf or entertainment center.

The HTPC hooks up to your TV via an HDMI cord which will transmit both video and audio for watching movies. If you have a home theater system, your HTPC can connect to that to enable surround sound on movies, or streaming music throughout your home. It would also require a network connection to access streaming services. Although WiFi is convenient, a wired Ethernet connection is ideal because it can support higher speeds and bandwidth which is better for HD media.

Once you have a basic HTPC set up, you can upgrade your setup with a better TV, speakers, or even a projector for that true movie theater experience. If you want to be able to access your media in several rooms at once, you can set up multiple HTPCs with Network Accessed Storage, or NAS. This is a central storage location that connects directly to your router that all the computers on your home router can access at once. This is a more efficient option than storing all of your media on each computer separately. They can even be set up with internet access so you can stream your media from anywhere.
