My experience with Dell is that they are not that focused on selling enterprise support (at least compared to HPE), at most they will push for bundling hardware (cables, cable trays, front covers, PERC...) that you do not really need in ord

Modern protocols running over RS-485 UART usually use some kind of HDLC-inspired framing scheme with flag characters and byte stuffing. But still there is a lot of stuff that uses ASCII STX/ETX and then some kind of field separators in

That is not an overloading, that is just preserving the behavior of Tab on IBM terminals.

The mishap involves doing touch-and-go twice with an arrested landing capable version of the aircraft. The report even says that they considered doing arrested landing, but it was deemed as too much risk for the pilot (apparently the actual

The article is somewhat sensationalistic. If you read the actual report you will find out that: The pilot was not part of the conference call! What froze was not hydraulic fluid for actuators (in some hydraulic line), but hydraulic fluid in

The actual report mentions that this was a concern for actually landing the plane (as opposed to touch and go), because there was real possibility that the plane would end up in attitude that can hardly be described as "roughly level&q

If you want the bare chips and not full assembled labels the usual packaging is uncut wafer and cutting out and handling the individual dies is your problem.

I did work with that recently. Did a few cool demos. The tags got cheaper and you can even get tags that are intentionally designed for metal surfaces. Unlike NFC (or barcodes, obviously), you can read hundreds of tags essentially simultane

Coax and high-current/voltage pins are not that weird. You can also get truly weird semi-proprietary pins like fiber optics or even pneumatics/fluidics.

IBM did that pretty often. And well, the original VGA connector had pin 9 missing and used as a key.

It is my understanding that Starlink does not do home-grown crypto of the 3GPP-kind. Also because it is closed ecosystem there is no need for SIMs and the associated deployment mechanisms.

Ruby in both its semantics and implementation is very close to smalltalk and does not really use the Python's object model that can be summarized as "everything is a dict with string keys". That makes all the tricks discovere

As for NCD X terminals (at least the later ones), surprising amount of stuff could run directly on the terminal (which ran some weird MMU-less BSD variant): mwm and motif session manager, dtterm-like terminal with telnet and serial port sup

This is not particularly novel. Essentially any large-ish retail warehouse I have been in uses some kind of layout similar to their "CPU-based layout". And I have seen warehouses that were not explicitly designed like that, but th

The original POSIX subsystem was just there so MS could say that it exists (and pass DoD requirements). It got actually somewhat usable with the 2k/XP version, slightly better in Vista (notably: the utilities installer had option to us

Working from the fact that the NetBSD sees the OHCI controllers which are on the Starlet's AHB this runs with AHBPROT disabled (as does most homebrew), so NetBSD can in theory not only interact with Starlet mailboxes (as any normal gam

Doing similar idea with asymetric cryptography is problematic due to the size of messages involved that are not exactly convenient to type. Lower bound for the signature size is going to be something on the order of 128bits if we include &q

And many actual implementations work the other way around. Which opens the user to credential compromise but is much better user experience (and only one possible with several kinds of hardware tokens).

In my opinion that was step in the right direction, but the protocol design is truly weird. Somehow managing to come up with 4 different ways to encode length of byte strings in otherwise so simple protocol is remarkable achievement.

Interesting contrast to this is that most modern vector 2D graphics API use PostScript/PDF drawing model that cannot represent exact circles and elipses and these are instead interpolated by a bunch of bezier curve segments.

If you want the resulting geometry to be precise you are pretty much limited to equivalent of compass and straightedge (or well, in mechanical engineering lathe and mill, which are basically the same things). if you start somehow calculatin

Another issue with modern recreations of old UIs is that the dimensions are usually subtly wrong, which for me ruins the feeling. Some of that is related to the fonts having different height, but in many cases it is just that something is o

There is a difference between DP+ and DP++. DP+ uses external level shifter, DP++ uses passive adapter and the card switches different transmitter into the path internally.

There are some motherboards that can switch either PS/2 or RS232 signalling onto USB-A connectors, but this is completely non-standard hack mostly seen on some enterprise stuff few years back that seems to have mostly died away.

AT keyboard (DIN5) and PS/2 keyboards are in terms of electrical signals and the low-level framing protocol equivalent. As for the higher protocol level PS/2 is technically an superset of AT keyboard, but when used on PC platforms
