Keyboard logging on Hewlett-Packard laptops

Versions of the Conexant audio driver on HP laptops can log every keystroke to disk, writing to a visible file in C:\Users\Public. Your passwords, everything.

So HP issued a driver update. But that driver update is reported to still have the logging capability, turned off. Logging can be reactivated with a simple registry hack.

My future plans do not include buying devices from Hewlett-Packard, or investing in Conexant stock.

Update: HP's official security bulletin on the issue. Meanwhile, the logger can be reused and exploited.

A couple of weeks ago I released SaVi 1.5.0 for simulating satellite constellations.

SaVi has a few new tricks; it can load in satellite elsets from the web, and create animations of satellite movement.

And it was pleasing to find that SaVi can be made to work on Windows 10 (Anniversary developer edition) via its Ubuntu package. I've never learned to build Windows applications, and that no longer matters!

I've been working on and off with SaVi for twenty years, pretty much. Now, back to the occasional bugfixes.

SaVi seasonal software development.

It's become my habit to use some of the downtime over the year-end break to... oh, said that about a year ago.

Once again, I did some software work over Christmas and released SaVi 1.4.9, for simulating satellite constellations.

This is mostly a maintenance release, which was needed to remove some old code that used tmpnam(), which modern linkers dislike. But it also adds some approximate simulations of LeoSat and OneWeb, which are "megaconstellations" currently competing to get constructed. (Mega? They're not even kilo...)

I'm having flashbacks to the 1990s, when I first started on SaVi, and big constellations like Teledesic and Skybridge were all the rage.

SaVi seasonal software development.

It's become my habit to use some of the downtime over the year-end break to work on development of the SaVi satellite software that I maintain.

This Christmas, I added a new multi-colour map projection, which is quite pretty to look at in 3D in Geomview, if not as clear or as informative as other renderings.

It's in development code, and snapshots featuring that and a simulation of the equatorial exclusion zone for geostationary satellites are available. I should do a 1.4.7 release early in the new year.

Update: SaVi 1.4.7 was released on 5 January 2015, and available for download.

SaVi on Raspberry Pi.

Discovered that my SaVi satellite constellation visualization software could be installed easily on a Raspberry Pi, which is far more powerful than what I began working on SaVi on, so many years ago.

And that SaVi is now available for a very wide range of architectures.

My PhD work is running on the big screen in the living room. Looks like I've finally gotten satellite TV.
