SCP vs SFTP: Which One Should You Use for File Transfer

SCP (Secure Copy Protocol) and SFTP (Secure File Transfer Protocol) are alternatives for FTP (File Transfer Protocol), which is useful for local, non-scheduled file transfers. All three can help accomplish moving files from one location to another over Ethernet. However, FTP sends data in plain text, while the other two use the Secure Shell (SSH) protocol for communication. What Is SCP and SFTP? SCP (Secure Copy Protocol) This is a non-interactive file transfer that uses the shell and a remote command only, to securely transmit files between two computers. This is a secure version of the previous RCP, and FTP uses the SSH protocol… Read more

Let us scale up your success together!

The top of the scale is smooth and sleek with the logo at the bottom end, the emblem in the middle and the digital display at the top end. The scale is available in white or black.


Underneath, closer to the bottom end, there is a battery compartment that takes 3 AAA batteries.



Underneath, closer to the top end, there is a button that allows you to toggle the weight display between kilograms and pounds.

Performance

This scale is relatively light and once I installed the batteries, the digital display immediately responded. It has an auto shut-off, so once you step on the scale it turns on and it turns off quickly when you step off. It is sleek and attractive and is easy to keep clean by just wiping it with a damp cloth. I did find a discrepancy in weight when I compared it with an existing digital scale, so I am not 100% sure about accuracy as yet. Since my existing scale showed me as lighter, I am going with that result (LOL).


Here are the simple steps to get going:
1: Download the app from the iOS or Android app store.
2: Connect the Rollifit app via your phone’s Bluetooth.
3: Step on the scale.

It took me a few tries to get the Bluetooth to connect but once the scale showed up in the Bluetooth device list on my phone, it remained with no issue and it connects once I open the app and step on the scale.

APP

The app gives you all of the previously listed information and allows you to keep the history as well as to set and monitor your goals. The following is a small sample of screenshots from within the app.




What I Like

  • The build quality
  • The information offered via the app
  • The continuous goal monitoring capability

What can be improved

  • The Bluetooth pairing process which for me was a bit quirky.

Final thoughts

I have been on a health-conscious journey for a while. I managed to lose between 50 ~ 60 pounds and have kept the weight off for over 3 years. Regardless of maintaining a supportive diet and exercise routine, my weight and body fat still fluctuate back and forth. This scale seems durable and well built and should work as a great tool for maintaining my progress and attaining new goals. A complete analysis of the capabilities and effectiveness of this scale is a long-term process, so I will provide an update at a later date.

Price: $49.99
Where to buy: The RolliBot website and Amazon

America returns to space – NASA and SpaceX

 

ARTICLE – When I was a kid, I loved space.  I couldn’t get enough of NASA and the Apollo program.  I was nine years old when Apollo 11 launched, and like most of the country, I was glued to the TV, fascinated by America’s space program. In fact, they told me I should become an astronaut because I was just taking up space in school, but I digress…

Ever since the end of the shuttle missions, America hasn’t really had much of a space program.  We have relied on the Russian space program to launch astronauts and supplies to the International Space Station (ISS). But that’s all about to change.

In this past month, NASA and SpaceX, Elon Musk’s space exploration company, successfully launched a SpaceX Falcon 9 from Cape Canaveral, on Florida’s space coast, to the ISS. The rocket was topped with SpaceX’s new Crew Dragon capsule, designed to carry American astronauts into space. The capsule contained a human analog named Ripley – think MythBusters’ Buster – a heavily sensor-laden manikin, to measure forces and to help determine how humans would handle the flight.

This flight also introduced new tech to the program.  Usually, when a ship docks with the ISS, the crew on the ISS use the ISS’s robotic arm to help the ship dock.  On this flight, the Crew Dragon capsule docked fully autonomously, a first in ISS history.

The capsule returned home after its five-day mission, successfully splashing down in the Atlantic. Now that the capsule, and Ripley, are home, the data will be analyzed.  Another launch is planned with a designed abort, to test astronaut’s ability to survive in the event a flight has to be abandoned after the rocket has launched.  Assuming it all looks good, we could see US astronauts, launching from a US launch site on a US built rocket for the first time in years.

In February 2018, a month after moving to Florida, I made the drive about 90 minute east to Titusville, just across the water from NASA’s famed launchpad 39A.  I got to watch the NASA/SpaceX launch of the Falcon Heavy, essentially three Falcon 9s duct taped together. (OK, it’s a bit more complicated than that, but you get the gist…)

On top of that was a capsule containing Musk’s own Tesla Model S roadster, with another dummy, dubbed Starman, belted in for the ride.  The Falcon Heavy is designed to carry people and cargo, into space, potentially to Mars.

The bottom line here is that it is a very exciting time for the US space program – the most exciting time since the beginning of the space shuttle program. It would be great to get back to the heyday of space exploration when the entire country had space fever and we all looked to the skies with awe and excitement.

22pen mini multi-pen review

CROWDFUNDING REVIEW – Pens with multiple ink colors are handy but they can be bulky. The 22pen from Mario Shimodaira is different. It’s a Kickstarter project for a pen that is small and thin enough to become part of your EDC and everyone who sees it will ask where you got it.

What is it?

The 22pen is a unique Japanese designed pen that holds two different inks/pens in one very compact package that clips in your favorite notebook like a bookmark.

Design and features

First of all, I’ve never seen a pen like this one. The design has a unique eye-catching look that makes me think of one of my favorite sci-fi TV series Firefly and begs me to pick it up and write with it. Which I was able to do because they sent me a pre-production sample.

The body of the pen is made of what feels like a lightweight plastic, but it’s really Italian cellulose acetate which is a premium material that is also used to make designer eyeglass frames. The 22pen sample that was sent to me has a cool tortoise shell vibe if a tortoise shell can be blue and brown.

The 22pen has the ability to use a variety of pen refills that include: Zebra 4C Ballpoint Pen Refill, Mitsubishi uni SE-7, Mitsubishi uni SXR-7 Jetstream Ballpoint Pen Refill, Pilot, and Cross-Mini-Ballpoint-Pen-Refill. Just pull out the refill and insert a new one whenever you like.

The pen is only about 4 inches long and is flat, so it feels kind of weird to write with it when you first pick it up. As long as you pay attention to how you’re holding the pen so that only one pen tip is touching the paper, it works great and it even works fine if you draw with both tips touching the paper at once.

The 22pen isn’t going to replace my everyday favorite pen, but it’s handy for people who like to keep a bullet journal or carry other small notebooks. I like it because I can write my todos with one color and then cross them off with the other color without having to carry two pens or a larger multi-pen.

Sure, you can do that with any multi-pen, but when I’m finished writing, the 22pen’s built-in gold plated clip lets me store the pen right inside my journal. And since the pen is so thin, I can still close the notebook cover as I normally would.

What I like

  • Unique design
  • 2 pens in 1
  • Stores in your notebook

What needs to be improved

  • Maybe make it a little longer

Final thoughts

If you’re a pen person, you will want a 22pen in your collection. At almost $60, it can be considered a bit on the expensive side. But it’s unique, interesting, can use a variety of refills, and small enough to clip to your notebook. As it stands, it’s the best mini pen I’ve used.

How can I buy it?

The 22pen campaign ends on 3/30/19 and they have already passed their funding goal of $4,499. You can pre-order a 22pen starting at $58. After the 22pen campaign ends, rewards are estimated to start shipping in June/July 2019. Visit their Kickstarter page for all the details.
