The 20mm profile also comes in multiple widths and double thickness combinations, so there is indeed a 80x20mm profile (4x1). Also, it’s 1 and 1.5 inch t slot, not 20mm. Weird name indeed.

The bug relies on undefined behaviour in the C language, but it’s exploitable is due to the way memory access operations are written in C. Equivalent Rust code would not be exploitable at a language level because that type of raw pointer ar

And the Window 7 fresh install conundrum, how do you install wifi drivers when your laptop only has wifi and no ethernet? I also have a vague recollection of needing to install windows 98 from a floppy disk boot, then upgrading to windows X

That’s a neat looking trick, will have to see how well it works in practice. I can’t see it working too well if you need to feed the wire into a through hole. My trick is to tin the joint and the wire, apply no-clean flux to either the join

Another factor, travelling on the Shinkansen is an experience in itself. JR pass maximises your chance of experiencing the bliss of high speed rail.

Don’t mess with a Cassowary. Fairly rare to see them in the wild outside a few places, but they give no grace. The ones in captivity will 100% have a go at you if you get too close to the fence.

Modern sensors seem to quite useless with something able to crunch the numbers, so this is becoming increasingly common. TI’s mmWave sensors (IWR series) incorporate a top of the line C674x DSP core that is clocked at 600MHz.

If something becomes important or necessary, the entire document would be leaked, or relevant sections documented. Thank you Scihub and libgenesis. The more likely outcome is the specification will become its last version. If the spec isn’t

I would say that patents and copywrite are orthogonal. A patent, hopefully, captures a truely new and original idea. Where as as copywrite encompass actual work. One huge problem with patentable ideas is that the idea should not obvious to

CRTs were all 4:3, and had better specifications than the LCDs of the time. Back then LCDs also followed PC standard 4:3 resolution. It wasn’t until LCD tech was cheap enough for mass production in TVs that 1080p monitors became the norm.

Offline, air gapped, and limit control at gateways. Is SCADA security really that hard? If it absolutely has to tap into you company’s cloud based SAP, make the interface hardware enforceable supervisory only?

I love solvespace, the UI is quick, minimal and easy to come up to speed with. I use it as a 2D parametric sketch pad, for 2D designs for laser cutting, making 3D models for kicad, and a few basic 3D printed fixtures, but it is in no way a

Thank you for sharing, gosh that must have been horrific to track down. There really is something about USB buses that cause the worst kinds of errors. I happen to know that the USB2 driver in the RPI 1/2/3/4 has a Linux kern

If your getting X’s, why bother? Every PCB place I’ve dealt with tells you test rate and success rate (nominal 95% not factoring in specifics of the PCB). For a prototype run, you are effective guaranteed 4.95x good PCB out of 5 Minimum ord

I wish they advertised it more! That reduction in annular pad plus the inner player geometry is a game changer. Effectively any 0.8mm pitch bga is completely prototype-able now.

The best reference I can point to is the Xilinx bga pdf in google. Basically, for given capability (geometry really) there are only certain ways of breaking out pads. You can either fit multiple (luxury of process), one, or zero traces betw

> Well... that's not necessarily true. For instance, even the cheapest 2-layer process that JLCPCB offers is capable of 0.127mm tracks spaced 0.127mm apart... which means you can lay down tracks at a minimum of 0.254mm apart. That&#

It is definitely worth pointing out that this isn’t new, the idea itself is truely fascinating and the author clearly articulates this is code as art. It is definitely eye opening once you read into the details. I stumbled across this when

When comparing skiing with snowboarding, the one thing you always hear is skiing is far easier learn than snowboarding, which is largely true. What no-one tells you is it’s far easier as a beginner to get yourself in a truely dangerous situ

Honestly, the situation is far worse and nuanced than that. You can not determine whether content is infringing on copy write because of content alone. Copyright depends on context. Situation 1. You buy a PDF ebook. You have legal rights th

By that I mean how IO is coupled to the processor. In AVR8 (and other older processors I presume) GPIO access was via a CPU register, thus a single instruction (one clock RISC) can directly modify the GPIO state. Every GPIO implementation I

Power OK signals are used to prevent latch ups in silicon due to power glitches. The signals will route to power management ICs to ensure a full reset with proper bringing up of the power rails on any power glitch.

It is very humbling to know I’m not the only person to have had to implement bit banged MDIO recently. If your PHY’s data sheet says clause 45 register access only and you don’t have GPIO access as the bus master, run away. Unfortunately I

Much more limited capability wise, but much tighter guarantees about latency. More like a 80Mhz AVR 8bit than an ARM coprocessor. The real shame of modern microcontrollers is the decoupling of peripherals and GPIO from the main processor. I

A capacitor plus pull up resistor will add an RC time constant delay on switch release, and for it to be effective at denouncing it needs to be on the order of 10ms. A software solution has zero delay in both cases. A Schmitt buffer isn’t n

Yes. Essentially, when you see an edge, update the state immediately but have a guard interval before allowing further state changes. Intuitively, this means register the event when you see the first edge, not once the bounces have finished

Great idea, but seeing as you are rearchitecting you might as well add the salt to the MD5 while you are at it.
