In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.
Fight me all you want, but it ain't a party without alcohol—whether it's a Halloween party, Christmas party, dinner party, or even a damn wedding. (If you think that people will stick around after dinner for a dry wedding, then you're sorely mistaken.)
If you're one who enjoys a good DIY project, or if you're just tired of paying exorbitant labor fees to have your vehicle serviced every 5,000 miles, changing your own oil can be a rewarding endeavor. Even though cars and trucks are becoming increasingly over-engineered these days, manufacturers generally see to it that the basic maintenance items can still be taken care of in your driveway with a few common tools.
There are countless methods and cleaners aimed at eliminating stubborn stains from everything to clothing, carpet, and furniture. But completely removing every last trace of a stain doesn't require an arsenal of chemical cleaners and repeated cycles in the washing machine. Most stains can disappear in a matter of minutes with a dose of alcohol.
In the aftermath of the unindicted police killings of Michael Brown and Eric Garner, we've been told that the system worked as intended. When our legal system's outcome is at conflict with what a majority of Americans believe is just, it's clear that some changes are needed. But what specifically needs to change? And what can an average citizen with a moral and just cause do to prevent these kinds of tragedies from repeating themselves again and again?
What if the code you are trying to reverse engineer is obfuscated or somehow corrupted? What if no way is left? Here comes what I like to call (wrongly and ironically) the "brute force of reverse engineering".
If you've been to a convention of any sort before, you know that there are good and bad panels, and that their inherent goodness or badness often has little to do with the actual content being discussed. That's because giving a panel is a skill that not everyone has. However, it is a skill that everyone could have! In this article, I'll tell you how to give a good panel on practically any subject.

This video demonstration series shows the process of creating an armature for stop motion animation, claymation specifically, out of aluminum foil and polymer clay. Armatures need to be flexible to withstand the positioning and repositioning required to make stop motion animation, but still secure enough so that the material won't break. For this reason, a tin foil skeleton provides a sound structure to the clay armature. Watch this video animation tutorial and learn how to sculpt an armature...

While Apple is full steam ahead on iOS 18, which is expected to drop sometime next month, it hasn't forgotten about iOS 17, which still dominates most users' iPhones. On Aug. 19, Apple issued a rerelease of its iOS 17.6.1 software for iPhone.
There are now more emoji on your iPhone's keyboard that you can send as reactions or stickers or insert wherever else you use emoji — and it's about time. It's been nearly a year since the last emoji update for iOS, and we only received support for 31 new ones then. The new iOS 17 software update brings almost four times as many.
Some phone lines make it nearly impossible to get past the busy tone, whether it's a viral call-in giveaway, your state's unemployment office, your local post office during the holidays, or the repair office for a broken warrantied product you have. Thankfully, there are apps you can use to help break through the noise.
A low-key iPhone feature that's been around since iOS 10 can make the iMessages you send to family and friends more exciting overall. One particular element is, if you'll forgive my decades-old slang, "da bomb" for emoji.
It's about that time again: Facebook has announced the dates for its annual Facebook Connect (formerly known as Oculus Connect until last year).
The fight to wrest control of apps from Apple's revenue-focused grip just took a major turn in favor of Epic Games.

Apple's exclusive chat services, iMessage and FaceTime, force many of us to stay locked into iOS, iPadOS, and macOS to communicate with other Apple users, so chatting with Android-using friends means SMS texts, third-party messaging apps, and third-party video chat services. However, Apple is breaking boundaries with iOS 15 so that we can FaceTime with Android, Linux, and Windows users.
IT is a competitive field, and finding success requires more than knowledge of a couple of coding languages or knowing how to google really well. To stand out among your peers and competitors, you should learn everything you can and get as much diverse experience as is available.

Whenever you need a flashlight, your iPhone's LED flash may be enough to break through the darkness, and you don't even need to unlock your screen to use it. But your LED flash's brightness level may be too strong or not powerful enough. It's not immediately obvious how one would change those lumens from the lock screen, but doing so is almost as fast as turning it on.
Tech-savvy programmers and developers usually apply their unique talents exclusively to creating apps and websites — two high-paying and exciting pursuits that can open countless doors and opportunities in multiple fields.
The moment arrives when you finally pop a shell on the web server you've been working on, only you find yourself in a strange environment with limited functionality. Restricted shells are often used as an additional line of defense and can be frustrating for an attacker to stumble upon. But with enough patience and persistence, it is possible to escape these restricted environments.
Since its original release as a spreadsheet program called Multiplan in 1982, Microsoft Excel has become the world's premier business software. If you think that it's only good for spreadsheets, you haven't been paying enough attention.

Not all 5G is equal. Even if you dropped the cash on a true 5G phone and you see it's connected to 5G in the status bar, that doesn't mean you're surfing the web, streaming Spotify, and binging Netflix faster than your friends with LTE phones.
If the interconnected worlds of blockchain, Bitcoin, and cryptocurrencies scare you a bit, you're not alone. Thanks in part to the extreme and seemingly random fluctuations in the value of Bitcoin over the past three years, more than a few developers and investors are wary of the cryptocurrency revolution and its ties to blockchain development.
It's finally here. After years of rumors and speculation, Apple unveiled the new iPhone SE on April 15. While it doesn't have a 4-inch display like the original SE, it's the smallest new iPhone you can buy today, with the chipset of the iPhone 11, 11 Pro, and 11 Pro Max. So, when can you get your hands on it?
We're glued to the news now more than ever, but our "free press" isn't necessarily free of charge. Cable news outlets like CNN and MSNBC are locked behind expensive cable TV packages and cord-cutting streaming subscriptions such as Sling TV and Hulu + Live TV. Luckily, there are plenty of alternatives to get your TV news fix, free of any payment, account, or commitment.
With stay-at-home orders for most of us in the US because of the new coronavirus, many of you are likely struggling to be productive and efficient when working from home.

The response to the COVID-19 pandemic means that social distancing has become the new normal. It also means that more Americans are using video conferencing to connect with colleagues working from home or friends and family in quarantine because of the new coronavirus.
In the iOS 13.4 update, Apple added folder-sharing capabilities in the Files app. That means you can share multiple documents at the same time instead of doing it one by one. But that's not all — you can share folders with numerous contacts and even enforce access and permission settings.
Apple released iOS 13.4 to registered developers on March 18. The update comes just hours after news broke that iOS 13.4 would hit all compatible devices on March 24. The update is the GM (golden master), which makes it the same build as the official release we expect to see on March 24, although Apple does refer to it as "beta 6" on the dev site.
