Chances Are Your Router’s Firmware Blows

Linksys WRT-54G RouterYou surely have a lock on your front door. Do you have such a lock on your network? Though you may think so, but it may well be wholly unlocked. Or at least, you may not be able to know for certain that it’s locked. If you use a commercial Wi-Fi router from your ISP, or one of the big names like Linksys, Belkin, DLink et al, your network may not be as secure as you think.

At the outset let me state that, as someone who reads hereabouts, you’re no dummy. You’ve taken steps to ensure that the router doesn’t still have  the default admin password. You’re using modern encryption on your Wi-Fi. You’re being responsible, but there are things beyond your grasp.

The simple fact is that the firmware the runs most retail, commercial routers is closed source. As such, you have no ready way to verify it’s behavior. Yet, the manufacturer, by virtue of necessity, uses various common software modules to create their firmware. They may even use some open source modules, but end up with an closed source binary in the end.

The upshot of this reality is that you have a very small team of developers responsible for maintaining the code. That means updates come along slowly, if at all for older devices. By extension, serious security issues get addressed slowly, if they ever get addressed at all.

VU Meters For Windows

Some time ago I noted the availability of installable audio metering for Windows. Today I stumbled upon a similar free application called “VUMeter” that provides old school stereo VU meters.

The meters can be resized from 50%, 100% or 200% of normal size, where  normal size is 1500 x 300 pixels.

They can be set to stay on top of all windows. They can also be set to display the signal from any available sound recording or playback device.

I Want A New Kind Of Desktop Webcam

Logitech-C920-WebcamYes, I want a new webcam! The idiocy of that statement doesn’t become apparent unless you’re familiar with my home office, which is littered with various webcams. They have become something of an obsession. Yet, none of them does quite what I’d like.

My reference for a simple USB attached webcam is the venerable Logitech HD Pro C920. One sits, a near permanent fixture, atop my left-side monitor. It’s a solid product. It’s affordable. Makes great video under various lighting conditions. It can deliver MJPEG or H.264 encoded streams, which makes it capable of 1080p when used with suitable software.

Behind The Scenes At VUC561 With Grandstream

gvc3200-right-300#VUC561 about the Grandstream GVC3200 was yet another example of bringing my broadcast video production background into the realm of vodcasting. In the pre-call walk-through Randy took a screen-shot of what he was seeing. It seemed a little busy. There was certainly a lot to look at.

Just for fun I thought I’d make note of what was actually there, and how it was being used.

There’s A New Headset Connector In Town

Sony TRRRS Connector MDR-NC31EMSome time ago I published a backgrounder on 3.5mm headset connectors. It detailed a bit of history of the 1/8″ (3.5mm) mini-plug, from the Sony Walkman of old to present day. That evolution could also be described as from “Tip-Ring-Sleeve”  (TRS) to Tip-Ring-Ring-Sleeve”  (TRRS.)  That post has proven surprisingly popular.

It’s been said that the universe is continually expanding. That includes the universe of mini-plug variants. Today I got my first look at the next step in the evolution of the lowly mini-plug; TRRRS!
