The book specifies that the park is ran by Cray supercomputer (IIRC there it even mentions particular model, probably Y-MP). For the movie it was replaced by CM-5, because it was deemed even more visually stunning, mainly because while Cray

Tamiko Thiel herself is selling CM T-shirts on spreadshirt. It is my understanding that the original TMC T-shirts also had print on the back, the spreadshirt ones only have the cube of brainy cubes design on the front.

CM-1/2 is not exactly computer, it is more of a massively parallel SIMD computation accelerator. While AFAIK the CM-1 microsequencer has some limited ability to handle control flow it is there mostly in order to futher compress the ins

In fact MS not only invented XHR (and the reason why is called that is because it originnaly was semi-documented internal Windows API), but they also invented bunch of HTML-native features that are currently being reintroduced into HTML5. A

I would say that the fact that firewire is a bus is part of the reason why it fell out of favor. It was designed in a time when packet switching was though to be expensive and to cause unacceptable latencies for A/V applications. Just

I believe that even the slim PS3 versions without full-blown GS+EE hardware still include the PS1 CPU somewhere in a role of IO controller.

You need the schema to deduce the meaning of the data contained in such encodings, you don't need it to safely parse the BER stream. Only slight complication is that you have to handle indefinite length constructed encodings of unknown

The issue with parsing ASN.1 is not inherent in the specification itself. The issue is about trying to produce DER/BER parser that is hardwired to parse particular instance of the syntax and directly fills some kind of C structs withou

All IDE drives are linear block devices and the CHS numbers set in BIOS are only necessary to make the BIOS happy. The types and CHS numbers were relevant for MFM/RLL harddrives without integrated controller. The IDE interface is essen

GALs are in essence ROM with both "halves" programmable (as the address decoding logic can also be implemented by mask or fuse programmable bit array). The end result is that you trade bit of generallity for smaller, cheaper and f

I would not be surprised if this trick was meant for early encapsulated foil capacitors. These were encapsulated in various semi-natural resins of not exactly known or repeatable properties (usually the intention was that the resin is hygro

It is not that clear-cut. Obviously the optimal case is SMD-only, but there is a threshold when THT-only becomes cheaper than SMD/THT mix. Another thing is that power supplies tend to use higher temperature board material (presumably t

Circuit that tries to do this directly from AC is going to be more or less equivalent to active rectifier followed by traditional SMPS power stage (including some kind of DC bus with some nontrivial smoothing capacitor). In case when the wh

Last time I looked at it it was not especially cost effective to build PC power supplies on multilayer boards. That leads to exactly the kind of construction as in this power supply: large almost completely through hole single-sided board w

The Android API gives me the feeling that the original idea was to do in-process sandboxing in mostly same way as it is done in Java and run the whole thing as one giant JVM instance and only later it was changed to the process-for-app mode

That depends. Nowadyas installing k8s is easy enough that it is probably the most strightforward way of getting automated deployments that is reasonably reliable. The only issue is that the control plane is somewhat heavy weight, which can

The main takeaway from this is that having one somewhat ill-defined definition of equality over the whole language ecosystem is a bad idea. There is a reason why typical LISP has 5+ different notions of equality in the base language. The ty

It is the other way around. The concept of public domain only works in countries (eg. US) that have the common law for-profit copyright approach. In civil law jurisdictions where the copyright legislation more closely follows the idea of Be

I would not say that it is acknowledged as a mistake. Sqlite originally comes from Tcl world and thus it is somewhat natural that it follows Tcl's stringly-typed object model.
