PyGest: A Python Tkinter Tutorial, Part 5

This is part five in our Python tkinter tutorial series, in which we are building a simple GUI app to process and check file hash digests. In the previous two articles (part 3 and part 4), we configured the input and output widgets for our app. In this post, we're going to build out our app's two primary buttons and hook them into the appropriate input and output fields.

Space Station Sunday: New Experiments And A Fresh Dragon

Good afternoon, space fans!  It's been another fascinating week aboard our favorite orbital outpost.  Here's what's up...

Peppery Pacification: New Crowd-Control Drones In India Feature Pepper Spray

Some police departments used to strive for "less-lethal" weaponry, leading to an influx of options like bean-bag guns, LRAD sound cannons, and all varieties of sprays and chemicals to subdue (but not kill) their targets.  Now, that premise has taken flight on a whole new level: pepper-spray drones.

We can't even control cops that over-use pepper spray...will machines do any better?

Bodies And Oddities: New "Figure 1" Medical Photo-Sharing App Offers Different Doctors' Opinions, Crazy Pics

One of the most popular social media apps, Instagram, has been growing in popularity so much that some users have even been abandoning their Facebook for it.  Now, an Instagram-type app has found a niche community for people who need to use the photos for research that goes further than what you're wearing or what you ate today.  Enter Figure 1, a photo-sharing app for doctors.

Bugs, Drugs, and Thugs: DEA Phone Tap Protocol From 1992 Onward Paved Way For Current NSA Programs

Many compelling arguments have been offered as evidence to stop the NSA and other agencies from spying on American (and others') phone calls.  Constitutional rights infringement, invasion of privacy, and simply wasting time and manpower are all noteworthy points that the programs should be stopped.  However, nothing justifies the removal of this century's scaled-up security state better than history itself:  powers-that-be have been monitoring calls for decades, and it didn't stop terrorists one bit...

It didn't really stop drug dealers that much, either.

We've Had An Orbiting Nuke In Space For 50 Years. Deal With It.

Uh...please don't freak out about this?

No seriously, promise you won't be weird about it?

Okay.  Happy 50th birthday to our orbiting nuclear reactor.

It's weird how 1960s ads make everything seem fun.

PyGest: A Python Tkinter Tutorial, Part 4

This article is part four in our ongoing Python tkinter tutorial series. When we left off in part three, we had just completed configuring the inputs for our interface, which included text entry, label and button widgets. We'll now move on to the widgets necessary for conveying the application's two outputs: 1) the hash digest value of the file input supplied by the user, and 2) a message indicating whether the file hash generated by the app matches the optional hash value that may be supplied by the user.
