https://sat-smt.codes/ is the best introductory to expert, and reference work I've ever read on SAT/SMT solvers

I just ran these past OpenAssistant and I'm seeing a much higher error detection rate. I've tried 6 so far, and it's caught bugs in about 4. OpenAssistant actually had a very good …

Wifi is a pretty difficult protocol, but fortunately Linux ships with mac80211. So all that is needed is an SDR based PHY such as https://github.com/Nuand/bladeRF-wiphy/ .

The "fix" Intel pushed out this week is a microcode update that in my experience doesn't fix or address Meltdown at all. The update does however make Spectre slightly less reliable…

Nope, it's all in the MAC and additional usermode services that help phones identify to the network using, in most cases, its SIM.

Eventually yes, we can expect to see optical in desktops. Fiber connections are "better" but also much more expensive. The price should eventually come down as volumes increase. Th…

Take a look at slides 9 through 15 of this presentation: https://pcisig.com/sites/default/files/files/PCI_Express_Ele... PCIe signals are generated by transceivers -- devices withi…

$6.9 billion? sounds like this fire is razing quite well

The Google ads ban does not affect players like LendingClub/SoFi/Avant since they are long term loans with interest rates similar to credit cards.

Yea, I am too

Been working on this for a few months, and just added the finishing touches. It's a high performance ADS-B receiver that can detect and correct multiple bit errors and packet colli…

Yes, you are correct. Some parts of LTE and WCDMA use a pre shared secret and rolling keys to allow UEs to identify themselves to the mobile network. There are however many non-dat…

It will depend on the material, but I don't think 802.11ad can even penetrate through sheetrock. Honestly it may even be so bad that a sneeze could knock your connection out for a …

The laser analogy is definitely accurate given today's technology. I just don't think they'll be able to productize something that has that high of an antenna gain. I'm really hopi…

60GHz also limits you to direct line of sight. 60GHz propagates similar to a spotlight.

The "statistic" seems to make a point that taking a bet on a strategy and losing is incompetence.

If you want an introduction to assembly with the hopes of achieving super complicated in the future, I would suggest taking a look at the Intel manuals [1]. Volume 1 specifically o…

Monitor mode is a MAC level concept, and doesn't alter any of the RF characteristics that would make operating this device illegal. (This is not legal advice. Consult with an attor…

OFDM 802.11 rates already have a significant amount of Forward Error Correction. 802.11g uses a convolution encoder and Viterbi Decoder [1], and 802.11 HT rates (n, ac, ad) can als…

OpenBTS and YateBTS need a full-duplex radio to function. So far only Ettus radios and bladeRFs [1] have those capabilities. The bladeRF is also the cheapest option, costing in the…

Cellphones are half duplex but the basestation is generally full-duplex. A half-duplex basestation could probably handle no more than one cellphone. OpenBTS and YateBTS, as well as…

The options, RSU, and NSO packages remain as-is. The only thing that changes is the tax situation. Excercising options after a stock is publicly traded is viewed and taxed exactly …
