"CAUTION: dead bodies!"

From t.me/The3rdForceUA

Special Operations Forces operators carried out a raid on a group of piglets who were trying to set up a new position and eliminated it.

The special forces were carrying out a mission near the border with the #RF and came under enemy artillery fire. In this situation, a decision was made to retreat to a safe zone.

@riley Case in point, #IrDA on optical bandwiths would work excellent for #DataExchange on #airgapped systems with minimal risk of violating #TEMPEST or similar standards, thus making RED/BLACK seperation in various projects on mine simpler.

  • Not to mention it's trivial to spoof or merely jam #wireless #RF like #NFC]* and thus denying the ability to use these, whereas it's harder to block a line-of-sight without being identified as root cause of it.

An #OpenSource, low-cost multinuclear #NMR #spectrometer operating in the mT field regime:

-high spectral resolution
-arbitrary #RF pulse programming
-requires #LabVIEW
-cost: k$ 20 (mainly PXI waveform generator & digitizer alone)
-cost could be driven down by half using a home-built RF amplifier made with high-power operational amplifiers

My previous intro post was a few years old, so behold, new intro post:

Mike. Live in the Seattle area having grown up in the UK as a full blown British. Have a wife (incredible), child (boy), and three dogs (golden retriver/cream retriver/fuck knows).

I work in information security, something I have done for about 20 years. By day I run corporate security, enterprise IT and various other bits and pieces for an EV charging startup. I am big into EV's and currently drive one that is not a Tesla. I want an electric motorbike, so if anyone has a spare one please send it.

I also have a company of my own, Secure Being (securebeing.com), which does pen testing and digital forensic work - it's my way of staying super hands on while still doing the management bits on the career path.

I have written books about information security things. Five of them. Two are non-fiction textbooks, and three are fiction based on real world #infosec things. Check out infosecdiaries.com and your local bookstore to find them, just search for my name. I have been trying to write more stuff, but always seem to find myself distracted by other things, such as work. linktr.ee/secureowl has some mini stories I've written.

I love radio and everything RF. I have lots of antennas and various scanners and radios on my desk. I love intercepting and decoding things, like digital radio protocols.

I am a big aviation nerd. I always wanted to be a commercial pilot. I gained my private pilots license in the UK at 17, all self funded by my employment at the local Safeway/Morrisons store. I did the sim test and commercial assessments, but for some reason, at 18, I was unable to find the £100k needed to complete the commercial training, so I did computers. But do not worry, because those computers and love of aviation and radio/RF combined, and I run a project called ACARS Drama. acarsdrama.com has all the details.

I play guitar and am a big guitar/audio nerd as well. I record music under the moniker Operation: Anxiety, operationanxiety.com - the music is on all the normal places.

Finally, I am a massive fan of motorsport. I believe I have watched every F1 race for the last 30 years, maybe 25. I also follow F2, FE, Indycar and MotoGP closely. I average around 18 hours of Le Mans 24 hour racing watching per year.

So there you have it. If you are looking for a thought leader on the topics mentioned above, you've come to the wrong place - because this is where I shitpost, and shitposting is cheap therapy.

Так!!
Чё за?!
Я уже совсем запутался: кто кого плагиатит - Фуми Кодаму или Кодама Фуми?!
Да это же почти плагиат на начало 1 главы "Кокитоса"!!
РЫНОК ЯПОНСКОЙ МАНГИ... ПОХОЖЕ, РЕАЛЬНО, В КРИЗИСЕ... КАК И ГОЛЛИВУД.

A few more RF Detectors tested with the fixed 100 MHz setup. These detectors were tested without the 10 dB fixed pad in the setup to allow going up to +10 input (with 10dB step attenuator set to zero position). Outputs from these diode detectors are measured in volts DC and measured with a DMM. Found a bad Narda 4506 that was thought to be good, so worthwhile measuring the lab stock today. #HamRadio #RF

Round 3: Comparing Mini-Circuits ZX47-55 detector with TinySA-Ultra. Setup a test using 100 MHz +13 dBm test oscillator, 10 dB pad, 0-70dB 10dB step attenuator, 2-way splitter yielding two measurement paths. RF measurement devices cost similar, ~$140 USD. TinySA-Ultra is more accurate and has wider range (and many other functions), but far slower. ZX47-55 is faster with a more limited measurement range. Outcome: Both have a place in the lab (more is always better, right?). #HamRadio #RF

Believe that I always learn something (sometimes lots!) while writing code for should-be-simple lab projects. This is certainly true with this simple RF power meter project. Here’s the Community Edition LabVIEW front panel that is reading the Mini-Circuits ZX47-55 power detector (via Digilent AD3 converter) while being driven by my ADALM-PLUTO SDR TX output at 100 MHz at -40 dBm. Still more fun ahead with this before calling it good enough. #HamRadio #RF #SDR #Digilent #GoodStart

Rainy day in EN52 Chicagoland - time to setup and test a Mini-Circuits ZX47-55 RF detector module to see if working or not. Measured DC Out vs 100 MHz RF level In and DC Out at -20dBm In while sweeping from 0.1 to 6 GHz. Result: It works as a RF detector module but DC output is not easy to use (want dBm, got neg-slope DC mV instead). Might make a LabVIEW program to display/chart dBm with Digilent AD3, or maybe write code for a standalone Arduino w/ display showing dBm… #RF #LabVIEW #Arduino

Следующая манга у меня в ридлисте - это "Верный Друг" от Эбан Фуми.
Я НЕНАВИЖУ ЭТУ МАНГУ. НЕНАВИЖУ. ОНА УРОДСКАЯ И ЧЕРНУШНАЯ. Но, как куратору манга-читальни, мне придётся совершить акт мазохизма ещё раз и перечитать эту гадость уже вместе с вами. Что-то, знаете ли, душа у меня её сама просит...
А там, может, и сиквел почитаем...
Кстати говоря, про эту чернуху, сделанную в худших традициях российских сериалов, даже в en.m.wikipedia.org/wiki/Blue_F написано.
