Hardware-wise both audio and video had converged on the exactly same thing: there is this buffer that should be scanned/played out. The fact that contents of this buffer is generated by bunch of specialized hardware for the video case

The bias of unwhitened output of almost any TRNG is hugely biased. For almost anything based on detecting some kind of radiation (which at the same time are exactly the kinds of TRNGs that are truly random according to current understanding

The signal coming from typical radiation detector is analog pulse train which you have to somehow convert into useful binary data. Simply sampling this analog value at some regular interval will create samples that are hugely biased to smal

The attacker who had already compromised the integrity of the system in question has to guess or probe for a random number with relatively low entropy in order to do something useful and straightforward with that already compromised system.

There is one giant hole in your argument: both stack cookies and ASLR are mitigations that are nothing more than automated security through obscurity in the first place.

AX.25 is to a large extent completely different beast than what people mean when they talk about "X.25 network". X.25 as a specification is to a large extent an "API" and not particular network implementation. AX.25 is c

As the digital scales go I was in the market for industrial scale almost exactly an year ago. At the first glance the stated accuracy is simply function of ADC resolution and maximal measurable weight. On the second glance it is mostly abou

Also, the wites leading to the switch seem like 0.05” IDC cable, which is horribly inadequate for mains application. The “jumper” is not some kind of low power config input, it simply shorts the midpoint of DC smoothing capacitor bank to ne

For GSM simply receiving everything on PCH does not buy you much, because even ignoring encryption (IIRC even PCH is encrypted) most of traffic there is simply RR sublayer signaling (RR PAGING REQUEST and RR IMMEDIATE ASSIGNMENT messages an

As for the title itself (and probably my understanding of NZ english), for me “panel heater” means one of the modern electric powered planar sources of IR radiation and after living for few months in flat heated by only such things I’ve fou

And since XP SP2 windows by default searches current directory as one of the last places that it looks into. It is not exactly perfect mitigation but probably works for most instances of this issue.

The form factor kinda reminds me of mostly misguided project I toyed with in early 00's. The idea was to get useful amount of computing power for massively parallel applications on shoestring budget by building 2D network of boards in

The issue with scripting engine for game is that for game your almost certainly need scripting engine with completely different semantics than whatever existing implementation will provide. Ie. you either need to save the state or replicate

This trick generally works, but is not guaranteed to work by DOS API. COM binary gets 4k paragraph allocation and nothing more, the fact that this allocation essentially always is at the bottom edge of free conventional memory is not even a

Looking at the schematics of some old models of BackUPS I found online the output relay needs to be powered in order to supply output from mains. Combine this with slightly funky internal power topology where +12V for internal logic comes m

Many manufacturer demos tend to be soma variant of that: ie. replacing LXI or some kind of RT-ish fieldbus with 5G. I somehow fail to see any point in making such things wireless.

Metallic ethernet is explicitly not designed to be used between separate buildings so you really should not use it for that application. The physical layer can survive surprising overvoltage conditions, but it is insufficient for lightning

Gamers and crypto miners do various nasty things to PCIe cards in order to use cheapest cable possible to extend it and actual hardware damage resulting from that seems pretty minimal.

Another reason for the lag is that the modulation scheme is complex and requires considerable time to both acquire the actual demodulator lock (in fact, the symbol in typical terrestrial DTV system is surprisingly long) as well to acquire s

One issue with open interfaces for these kinds of applications is BT-LE itself. It is nominally designed as open standard for transferring exactly this kind of data, but it cannot do anything else than SNMP-like get/put/trap on s

The “Java bloat” mostly has nothing to do with the language itself, but is caused by the ecosystem around it. On one hand you have overly abstract frameworks and on the other you have inexperienced programmers who don't understand how

Main benefit of PLAs over ROM is that for many "useful" logic designs the resulting array is significantly smaller. In fact, ROM is simply an degenerate PLA where the AND array is fixed and only the OR array is programmable.

The <4U size was meant as approximation of the expected market segment and the number itself came to me as “anything smaller than smallest 6k5”. In fact I just wanted to avoid the “entry-level” moniker. Another question is router vs. swi

I would like to add that on almost anything made by Cisco that is smaller than 4U there really is not any kind of hardware secret sauce. Small switches like 2960 are little more than off-the shelf switching fabric from one of the well-known

I would say that most of the weirdness of Tcl is not caused by age, but because at its core it is nothing else than shell without all the tradional unix shell syntactic cruft. In the end Tcl is nothing else than shell with exactly two quoti

One thing of note is that 1000-base-T and G.991 (marketed as SHDSL/HDSL/SDSL depending on country/telco) is somewhat similar technology that is hard to classify as being baseband or broadband. One of my somewhat more absurd n

If you assume some kind of error correction the question stops being “would it work” and instead becomes “how slow/fast would it be”

My reading is that it is not that much about open standards between components (which are supposed to be somewhat open and interoperable already), but about open and vendor-neutral OAM interfaces.
