You Know What? Go Ahead and Use the Hotel Wi-Fi
This advice comes with plenty of qualifiers. If you’re planning to commit crimes online at the Holiday Inn Express, or to visit websites that you’d rather people not know you frequented, you need to take precautionary steps that we’ll get to in a minute. Likewise, if you’re a high-value target of a sophisticated nation state—look at you!—stay off of public Wi-Fi at all costs. (Also, you’ve probably already been hacked some other way, sorry.)
But for the rest of us? You’re probably OK. That’s not because hotel and airport Wi-Fi networks have necessarily gotten that much more secure. The web itself has.

Dependencies in open source
The topic of securing your open source dependencies just seems to keep getting bigger and bigger. I always expect it to get less attention for some reason, and every year I’m wrong about what’s happening out there. I remember when I first started talking about this topic, nobody really cared about it. It’s getting a lot more traction these days, especially as we see stories about open source dependencies being wildly out of date and some even being malicious backdoors.
So what does it really mean to have dependencies? Ignoring the topic of open source for a minute, we should clarify what a dependency is. If you develop software today, there’s no way you build everything yourself. Even if you’re writing something in a low level language there are other libraries you rely on to do certain things for you. Just printing “hello world” calls into another library to actually print the text on the screen. Nobody builds at this level outside of a few select low level projects. Because of this we use code and applications that someone else wrote. If your business is about selling something online, writing your own web server would be a massive cost. It’s far cheaper to find a web server someone else wrote. The web server would be a dependency. If the web server is open source (which is probably is), we would call that an open source dependency.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
