I meant that as in contrast to build tracking the sector the thing is in. Due to that you can have two sectors that intersect not only in 2D, but even in 3D and the engine still does the right thing (ignoring the fact that the renderer gets

Another issue with DSL bonding is crosstalk, which is pretty bad in many cases of telco wiring. 10 years ago there was a huge amount of surplus Cisco 1700s with SHDSL line cards (apparently coming from Czech government's project to con

Room over room (as done in later build games) usually does not require the sectors to overlap in this manner as it is a different thing (it is extension of how swimable water works, where the engine renders the other sector instead of floor

Most of the registered ports are for long forgotten services. This is compounded by the fact that many such services used multiple ports.

Autogenerated security audits that flag totally irellevant CVEs are another symptom of the same problem. Such scans usually only compare the version of the package in question, which breaks badly when distributions backport security patches

There have been more CVEs for the last 5 or so years. The reason is that "number of CVEs" is used in InfoSec community as kind of performance metric, so the "researchers" are incentivized to report total non-sense as sec

There is the cable used for things like LapLink and PLIP, that was inherently bitbanged. Then in theory with ECP you could connect two PCs with straight-thru cable and get something like 500Mbps with DMA support from that, on paper it was f

The PC game port is a nearest thing to intentional GPIO that PC has. Parallel port is almost always better for digital GPIOs, but it was not designed that way and the fact that it can be used like that (and extended several times into what

UUIDs were invented for distributed computing. But distributed computing in the original true sense of the term, not in the current sense of getting horizontal scalability for what is in the end one big application.

It seems to not be a true spreadsheet with dependency tracking and instead it recomputes everything after each change. Whis probably kind-of obvious as how to track the dependencies for arbitrary Python code is not that obvious. But without

It is somehow weird to see MPC821 in this kind of device. The point of (Power)QUICC line is that the Communications Processor is some kind of RISC/VLIW core, that offloads various communications tasks and has firmware support for vario

That is one of the 16bpp high-resolution icons that came with Plus for 95 and IIRC by default with NT4. So the most probable place where you would see that is NT4 desktop (and indeed it looked somewhat out of place).

The deflection circuitry of a TV or raster-scan CRT monitor is not designed to be driven by random X-Y signals and optimized around the sawtooth patterns of the raster scan. One thing is that driving the deflection coils of large-ish CRT at

The nasty thing about HF burns is that you often do not notice that something is wrong until you either smell the burnt skin or the burn starts to deep enough to become acutely painful. It is perfectly possible to burn 1mm dia hole complete

While you are right there is one pretty important additional point: the whole concept of network entry point. Building this kind of security perimeter invariable leads to internal security becoming ignored and everything inside the network

IBM sold that as BladeCenter QS series. Reportendly there even was an prototype version that had essentially same hardware as PS3 including the optical drive (production ones are dual-CPU without GPU and optical drive).

It is an EPROM (apparently 8x8KB 2764 in particular), EPROMs are not really intended to be in system (re-)programmed, so storing the IR codes in it does not really make sense. Proximity of pair of ALS193 to that EPROM makes me thing that it

One big reason is that it was 20 years ago. At that time, gcc only did rudimentary data flow analysis and full SSA dataflow was at best an experimental feature. Also, the market would not really accept a C compiler that does the kind of agr

In this case the primary reason for configuring it as point to point links is that it matches the hardware topology. In theory there is a standards compliant way to create an ethernet-style network from this, but there are two critical soft
