Password Rodeo

0

Here we are, once again someone has posted usernames and passwords they claim to have taken from some service by nefarious means. This will continue to be a problem as long as we are use some means to protect our things. Dropbox is our current scare.

Security breaches will happen and that can not be changed, what can be changed is your password. By using a long unique password you can protect your services. When these breaches occur and one of your services is affected you need to change the password to it as soon as possible. This will close the door on the breach to your data.

The best protection is to use two factor logins, which some services can provide, long passwords are the next best protection. These can be a problem, especially 20 character random passwords. To solve that problem I use a password manager. With a password manager I can store the many unique passwords for my services and generate new ones.

There are several services and apps that will help you safely store your passwords. I use Lastpass.com, free for web use and currently $12 per year to have premium access including from your mobile device. Here is a list of password managers that is maintained on Wikipedia.

A better way to share

0

As you may have seen in a previous post, I am looking at methods of posting to multiple networks at one time. This is an obvious need when trying to connect with a broad audience who use different social networks.

I found a web based service called Composer.io. It will allow you to setup API connections with many social networks.  Unfortunately it will not post to gPlus. It did however work just fine posting to Facebook, Twitter and my blog here. My blog software, wordpress self hosted, had a method of posting to gPlus. It posted a few too many copies though so I will stick with the current method, WordPress Jetpack Publicize. I’ll be using it to share this post for comparison.

I think it is important that if you plan sharing in multiple network you have a way to write once and post to many. This make the task far less tedious and increases the amount of people you can get to in a minimum of time. This post will be shared via the Jetpack plugin that is free from WordPress. You can also do  this with the free version at wordpress.com, in the sharing section of manage my blog. WordPress currently can post to Facebook, Google+, Twitter, LinkedIn, Tumblr and Path.

What service or app do you use to share your thought with the world?

I am testing a multiservice posting site called composer.io. Hopefully this will get posted completely and correctly. Let me know!!

An Arduino Project

Computer on a punch card

0

My latest Arduino excursion is the Paperduino Tiny. It is an eight pin package, the ATtiny85-20PU. It is an interesting circuit, laid out on a paper card and connected on the back with long leads and a few extra wires. It appears to be based on a small version of the Arduino family called Digispark.

You will be pointed to the digispark site for the IDE.

The instructions are set out for you to acquire all the components and assemble it, including burning the bootloader into the chip. I opted for the kit version offered on the site, but it appears the kit is no longer available.

If you decide to give it a try, go slow and use care.

My paperduino sketch, a mix of the fade and melody sketches, is posted on github.
