This week Jonathan Bennett and and Randal Schwartz chat with Michael and Benedikt about Emba, the embedded firmware analyzer that finds CVEs and includes the kitchen sink! It does virtualization, binary analysis include version detection, and more.

The modern web has become difficult to navigate without ad blocking software. Ford now has a patent that would bring the ads we hate to your vehicle’s infotainment system. [via PCMag ] Ford has already replied to criticism with the usual corporate spiel of patents not necessarily being the direction the company will go with future products, but it’s hard to imagine that other automakers aren’t planning similar systems since they’re already charging extra for heated seats, EV range, and performance. Bringing ads to the captive audience of your personal vehicle and targeting them based on listening to the occupants’ conversations would be a new low. Maybe you’ll be able to pay an extra $100/month for the “ad-free experience.” Instead of taking advantage of the EV transition to make better, simpler cars , automakers are using their highly-computerized nature to extract more from you and provide less when you drive off the lot. Enshittification has come for the automobile. Perhaps au...

The 1990s seem to have reached that point at which they are once more considered cool, and ephemera of the decade has become sought-after. One of the unlikely software hits from the period was Winamp, the MP3 player of choice in an era when time spent on dodgy file sharing sites or peer to peer sharing would snag you almost any music you wanted. Decades later its interface is still widely copied, but now you can try the original again as its source code has been made available . It’s not what we’d call open source though, even though they seem to be making an effort to imply as much with phrases such as “ opening up its source code “. If you’d like to have a go with it you can snag a copy from this GitHub repository , and you’ll need a particular version of Visual Studio 2019 to build it. Any celebrations will be muted though by paragraph five of the Winamp Collaborative License , which prohibits distribution of modified versions or forks, and stipulates that only the official mainta...

Developing your own film is an unabashedly analog process, which is one of the reasons people still gravitate towards it. After spending all day pushing buttons and looking at digital displays, spending some quiet time in the dark with pieces of paper and chemicals can be a way to decompress. But that doesn’t mean there isn’t room for a bit of modern digital convenience. Specifically, [John Jones] wanted a timer that offered more features than his old school analog model, so he decided to build one himself . He took the long away around to make sure the end result would be a tool he could rely on, which meant getting a custom PCB made, 3D printing a case to fit in with his existing workspace, and designing a control panel that he could operate in the dark. The PCB plays host to an ESP32 development board and an I/O expander that connects up to the array of LEDs, switches, and buttons on the front panel. The bottom-half of of the 3D printed enclosure is pretty simple, but the contro...

[Julius Curt] needed to mark acrylic panels with a bit more clarity than the usual way of rastering the surface, so they attempted to 3D print directly to an acrylic sheet , which worked perfectly. The obvious way to do this was to bond the acrylic sheet to the bed with glue temporarily, but another way was tried, and it’s much less messy and precarious. The bond between a 3D print and acrylic is very strong The first step was to create a 3D model which combined a constraining ‘fence’ to contain the acrylic panel with the required artwork floating above. It was easy enough to run the print long enough to build the fence, then pause the print mid-way to add the pristine panel and restart after a quick re-prime and wipe. There were a few simple takeaways from the video below. First, to ensure sufficient tolerance between the fence and the panel, consider the layer width (plus associated tolerance when printed) and the laser kerf of your machines to ensure a not-too-sloppy fit. Seco...

Although it’s still possible to grab a couple of friends, guitars, and a set of drums and start making analog music like it’s 1992 and there are vacant garages everywhere yearning for the sounds of power chords, the music scene almost demands the use of a computer now. There are a lot of benefits, largely that it dramatically lowers the barrier to entry since it greatly reduces the need for expensive analog instruments. It’s possible to get by with an impressively small computer and only a handful of other components too, as [BAussems] demonstrates with this tiny digital audio workstation (DAW). The DAW is housed inside a small wooden box and is centered around a Behringer JT-4000 which does most of the heavy lifting in this project. It’s a synthesizer designed to be as small as possible, but [BAussems] has a few other things to add to this build to round out its musical capabilities. A digital reverb effects pedal was disassembled to reduce size and added to the DAW beneath the syn...

Everyone knows that time’s arrow only goes in one direction, regardless of the system or material involved. In the case of material time, i.e. the ageing of materials such as amorphous materials resulting from glass transition, this material time is determined after the initial solidification by the relaxation of localized stresses and medium-scale reordering. These changes are induced by the out-of-equilibrium state of the amorphous material, and result in changes to the material’s properties, such as a change from ductile to a brittle state in metallic glasses. It is this material time which the authors of a recent paper ( preprint ) in Nature Physics postulates to be reversible. Whether or not this is possible is said to be dependent on the stationarity of the stochastic processes involved in the physical ageing. Determining this stationarity through the investigation of the material time in a number of metallic glass materials (1-phenyl-1-propanol, laponite and polymerizing epo...
