Is TCP Finally Showing Its Age? Homa Takes Aim at the Data Center

TCP has been around for so long that it is easy to forget just how much of the Internet depends on it. Web traffic, cloud applications, file transfers, databases and countless other services have relied on TCP for decades because it does a very good job of delivering data reliably and in the correct order. But there is a problem: the networks TCP was designed for are not necessarily the networks we are building today.

That is particularly true inside modern data centers. AI clusters can contain thousands of GPUs that need to exchange enormous amounts of data while simultaneously handling thousands of much smaller messages. A few milliseconds of additional latency might not sound like much when you are downloading a file, but when an expensive GPU is sitting idle waiting for another piece of information, those milliseconds can become very expensive. Stanford professor emeritus John Ousterhout is arguing that this is where a different transport protocol, called **Homa**, deserves a serious look.

Profitap IOTA 1G M12: Industrial‑Grade Network Probe for Real‑Time Capture & Analysis

If you work in industrial or enterprise networking, the Profitap IOTA 1G M12 is one of those tools that instantly makes your life easier. It’s a multifunctional passive probe that lets you capture, analyze, and troubleshoot traffic without dragging a full toolkit onsite. According to the datasheet, “The IOTA 1G M12 is a multifunctional passive network probe with integrated traffic capture and analysis capabilities.” This means you get a compact device that behaves like a tap, a capture appliance, and an analytics engine all in one. Whether you’re dealing with factory‑floor automation networks or a messy enterprise VLAN jungle, the IOTA gives you visibility without disrupting anything.

Pentagon HR System Breach Exposes Data of Nearly 3 Million People

The U.S. Department of Defense is dealing with a major cybersecurity incident after hackers breached a personnel management system operated by the Defense Manpower Data Center (DMDC). According to reports, unauthorized users gained access to sensitive records belonging to more than 3 million individuals, making this one of the most significant government-related data exposures reported this year.

Using iPerf3 to Test and Validate a Wireless Link

When troubleshooting or optimizing a wireless link, it is easy to look at the signal strength and assume everything is working properly. Signal levels are important, but they don't always tell the whole story. One of the tools I like to use is iPerf, because it lets you put actual traffic across the link and measure what the connection can really deliver. In this example, I was testing a Ubiquiti Wave Pro wireless link while it was being realigned. Rather than relying only on the radio's signal information, I wanted some real-world performance data to show whether the alignment changes were actually making a difference.

Your ChatGPT Chats Aren't Private — They're Turning Up as Evidence in Court

Here's an uncomfortable truth a lot of people haven't clocked yet: your late-night ChatGPT venting sessions, your "hey can you help me word this email to my ex" prompts, your half-formed legal or financial worries — none of that is protected the way a conversation with your lawyer, doctor, or therapist would be. A recent Washington Post investigation, picked up and expanded on by outlets like gHacks and TechSpot, found that AI chatbot conversations have already surfaced as evidence in at least 12 public court cases over the past two years. And that's almost certainly the tip of the iceberg, since most discovery material never becomes public record in the first place.
