Technology companies cannot be bought with money alone. Anonymous 08/31/2022 (Wed) 20:12 [Preview] No. 15121 [Reply] [Last 50 Posts]
Technology companies cannot be bought with money alone.

The main reason why Elon Musk could not buy Twitter is because technology companies cannot be bought with pure money power.

In order for you to actually buy technology companies, you need to deter other power elements related to the relevant technology company and secretly take control of the electronic, cybernetic and telemetric devices used by those companies beforehand.

Before purchasing, you should also secretly control the employees of the relevant technology company.

The real owner of Twitter is MOSSAD. The American Nationalist Forces behind Elon Musk are actually trying to buy Twitter from MOSSAD. Since the original owner of Twitter is MOSSAD, it is difficult to secretly take control of Twitter employees and the servers and other devices Twitter uses. Because of this difficulty, Elon Musk and the US Nationalist Forces behind him are prolonging the process with various excuses.

SpeakUp: Silent Speech Interface; Low Cost; Arduino; Machine Learning

Project Summary by Varun Chandrashekhar: "I have designed and developed a speech interfaced for the paralyzed, which they can use to communicate without speaking. This device detects speech-related electrical signals from the throat and converts them into letters or words that we recognize using machine learning models."

SpeakUp - ML Based Speech Aid to Enable Silent Communication https://create.arduino.cc/projecthub/Varun_Chandrashekhar/speakup-ml-based-speech-aid-to-enable-silent-communication-ffd9f8

My comment about the project: easily replicable by anyone with computer science knowledge, different from what is being done with the silicon trojans in the 3G/4G/5G equipment only on it needing physical probes. Anyone doing research on this area be cautious of sabotage when using US designed CPUs (AMD/INTEL/QUALCOMM/APPLE/ARM), as the microcode, SMM and firmware of your system may be manipulated to mess up your computations. Ask your own Nation to stop trusting Silicon Valley and make your own silicon supply chain and tech services. Meanwhile, mitigate this situation by moving to an area away from any cell radio transmitter (check coverage on OpenCellID.org) and shielding yourself and your devices from electromagnetic eavesdropping and interference.

Cool proyect. Does it need to have a Mega? What would be the problem using a Uno? I was just thinking the Mega is too bulky and the Uno is smaller.
And as far as I know the ARM is UK based, so no naughty US surveilance. Can't remember what band the XBee uses but I'm sure you could write some encryption for it, because I remember it being like wifi, just try not to send unencrypted thing on the air unless you want to.

San Diego ER seeing up to 37 marijuana cases a day — mostly psychosis

https://nypost.com/2022/10/22/san-diego-er-seeing-up-to-37-marijuana-cases-a-day/

“We’re now counting 37 cannabis-related diagnoses a day,” Dr. Roneet Lev, an addiction medicine doctor at Scripps Mercy Hospital in San Diego, said about her emergency department. “It’s been steadily increasing over the years. When I started in the 1990s, there was no such thing. Now I see 1 to 2 cases per shift. The most common symptom is psychosis.”

Article tells a story of a 19 years old that suicided after saying his room was bugged and his parents were trying to kill him.

“Specialist” still have no clue. Drugs don’t cause these. Criminals with microwave weapons wait for people to take drugs and then start messing with them so the victims’ testimony is made not credible by the drug association. Genetic relation is also inexistent, the criminals just target people who are related because they are already familiar with relatives.

Leaked Documents Outline DHS’s Plans to Police Disinformation
October 31 2022, 9:00 a.m.

Behind closed doors, and through pressure on private platforms, the U.S. government has used its power to try to shape online discourse. According to meeting minutes and other records appended to a lawsuit filed by Missouri Attorney General Eric Schmitt, a Republican who is also running for Senate, discussions have ranged from the scale and scope of government intervention in online discourse to the mechanics of streamlining takedown requests for false or intentionally misleading information.
[...]
There is also a formalized process for government officials to directly flag content on Facebook or Instagram and request that it be throttled or suppressed through a special Facebook portal that requires a government or law enforcement email to use. At the time of writing, the “content request system” at facebook.com/xtakedowns/login is still live. DHS and Meta, the parent company of Facebook, did not respond to a request for comment. The FBI declined to comment.
[...]
To accomplish these broad goals, the report said, CISA should invest in external research to evaluate the “efficacy of interventions,” specifically with research looking at how alleged disinformation can be countered and how quickly messages spread. Geoff Hale, the director of the Election Security Initiative at CISA, recommended the use of third-party information-sharing nonprofits as a “clearing house for information to avoid the appearance of government propaganda.”

Corporations give "donations" to both political parties, Democrats and Republicans. That chart only shows their conservative "donations", but compare it to "donations" to liberals and progressives and I bet you won't be so worried. It does not change the fact that nearly all Big Tech is heavily influenced and infiltrated by governmental interests. All you need to look at are the Twitter leaks coming out, and it's not only exposing Twitter anymore, the documents and emails reveal this is much deeper and the same is happening to Facebook and other tech companies too! Anons are connecting dots and finding out these intel spooks are all over the place when it comes to content management and purging undesirable information. This is how totalitarian governments control public narratives. This is how totalitarian governments maintain their propaganda. They censor and "shadow ban" their political dissidents.

[BBC News] Enigma da síndrome de Havana, que ataca diplomatas americanos e intriga cientistas

https://youtube.com/watch?v=Gi1ZyWLex2E [Embed]

Espionagem Eletromagnética e Mandantes de Adélio Bispo

Quando o Presidente diz que "5G é usado para espionagem" e que "urnas são passível de fraude", ele está correto mas não sabe como apontar evidência. Eu sei e fornecerei um método experimental para que a Polícia Federal possa se convencer disso. Porém, não somente urnas, mas todos os computadores e celulares (os da União inclusos) são passíveis de interferência e não é apenas o 5G que é responsável por espionagem eletromagnética, mas silicon trojans implantados nas torres desde o 2G. Isso permite não só controlar os silicon trojans nós processadores, mas também é usado para causar a Síndrome de Havana que atinge pessoas pelo mundo.

O modo de espionagem sendo usado para manipular pessoas como o Adélio Bispo a cometer crimes é usado no Brasil por um grupo também responsável por sites de ódio como "Dogolachan" e mercados de drogas como "Nightmare Market". Porém eles são apenas usuários do sistema de espionagem, que também é usado internacionalmente. A tecnologia é americana mas não governamental. Como os dados obtidos com essa espionagem também abastece serviços automatizados de recomendação de propagandas e conteúdo (outro método de gerar dinheiro para eles), há uma abertura para demonstrar que sistemas não conectados a internet estão vazando informações através dessa espionagem eletromagnética.

Quando uma empresa como o NSO Group oferece o Pegasus, eles fazem uma demonstração para que fique claro que conseguem acessar dispositivos celulares. O que estou oferecendo é um modo de demonstrar a ocorrência de espionagem eletromagnética que obtém dados de todos os computadores de modo contínuo. Uma vez evidenciado isso, indícios dos crimes facilitados por essa espionagem ficarão crediveis.

Minha Denúncia ao Ministério Público Eleitoral Sobre Fraude Nas Eleições 2022

Consta na ata eleitoral da zona 22, seção 498 que a urna da seção precisou ser substituída por problemas técnicos.

Eu fui informado (por hackeamento de um dos meus dispositivos) pela quadrilha chamada Dogolachan/1500chan de que a urna foi danificada propositalmente com a alteração remota de seus programas internos se valendo de vulnerabilidade interna ao processador da máquina e controlada remotamente com ondas eletromagnéticas - possível pois a urna usa processador com vício oculto de fábrica e a sua parte externa não previne que ondas eletromagnéticas externas afetem os componentes internos.

O objetivo da quadrilha com esse ato foi atrapalhar o direito ao voto do denunciante, que vota em tal seção. O motivo é que eu não quis participar da quadrilha nesses e outros crimes, preferindo denunciar seus delitos.

Não conseguindo impedir a votação pois a urna foi substituída, agiram de modo diverso na próxima urna, alterando o código executado na urna enquanto eu, denunciante, votava. Para modificar meu voto (que eu não reconheço registrado no Registro Digital de Voto, como constatado posteriormente à publicação desses pelo TSE).

Sabendo dessa sabotagem ainda enquanto na cabine de votação pois os criminosos alteraram o monitor da urna para exibir mensagem zombando da justiça brasileira e do TSE, eu procedi a comunicar ao presidente da mesa do ocorrido e foi registrado em ata minha queixa sobre a fraude na urna substituta.

Deve ser apurado com análise forense que os processadores Intel usados nas urnas (X5-E3940 e Z510P) dispõe de vício oculto inseridos na fábrica que permite total controle remoto a esses criminosos, escapando das medidas de segurança implementadas pelos programas do TSE pois executam em nível mais privilegiado do processador (Intel ME).

Os criminosos se valem disso para interferir no processo eleitoral (e em qualquer computador e celular no Brasil e exterior). Os testes de integridade são incapazes de atestar a fraude pois os criminosos atuam em tempo real monitorando todas as urnas e fazendo alterações apenas nas que não foram selecionadas para avaliação.

Os delito se enquadram na Lei das Eleições (9504/1997) art. 72 e no Código Eleitoral (4737/1965) art. 312 e art. 317.

Vigilância Eletromagnética nas Eleições - Ciência Cidadã

Participe como cientista cidadão em uma investigação de se as grandes companhias do Vale do Silício violam o sigilo do voto.

Coleta de dados:

Antes do dia da eleição, colete três embalagens de produtos usados por você e os coloque separadamente em três envelopes de modo que não se possa diferenciar por fora qual embalagem está em qual envelope.

Leve-os para a cabine de votação no dia da eleição - lugar no qual não é permitido o uso de celular - e abra um deles aleatoriamente. Então pense, escreva ou fale baixo "eu quero comprar [nome do produto respectivo]".

Uma vez fora da cabine, descarte os envelopes/embalagens antes de voltar a ter contato com seus eletrônicos.

Observe se lhe são exibidas propagandas que correspondem ao produto selecionado aleatoriamente.

Envie seu relatório com o maior nível de detalhes possível.

You can never be sure that VPN is really not logging anything but if I would have to choose a VPN, I would choose Mullvad and nothing else.

Remember that VPN only gives you privacy. For anonymity use Tor or any other anonymity network depending on what your country/ISP allows.

Be careful with this one. When using Freenet you are hosting everything that you will ever come across, which means you can easily host CP without even knowing that. All it takes is some troll posting that on perfectly legal site. Depending on the country you can get in trouble for that so it's much better to use Tor or I2P.

If your only concern is privacy, not total anonimity, then rent a cheap VPS and use it as a VPN (Wolfgang has a video on that on YT) you'll be guaranted to not have your activity logged. It will be easier to find you if you're doing illegal things tho, which I advise you to stay away from.

I didn't hear much about t420 but thinkpads are best laptops I ever used so you should be fine. I recommend getting T440p or X230 though. Keep in mind that most of them (thinkpads) have BIOS locked so that may be an issue for you depending on how much control you want to have over your machine.

1. They should be free, corporate surplus, etc. I have literally over 100 sitting in storage, that I haven't had time to go through - Unusually I dump 10-15 in a box and bring it with me when I fly overseas. They go for about $100-150 easily.

2. The LCD's really suck, and sure you can get in the moneypit of replacing LCD and more, but it isn't worth it.

3. Reliable? Every laptop nowadays is reliable hardware wise.

4. Safe, good question anon, what is safe. Lenovo stuff, Dell Stuff and Apple stuff are relativelt safe, you can lock down the bios/efi and make it hard for most people outside of state enterprise to break in. They all have TPM, and you can do "secureboot" via EFI and disable the legacy shit - the TPM chip on the t420 is easily physically dumpable though with a buspirate or such. I've done it.

Wifi support cards also are eh, you need to change it out - once again not a big deal but money sink for 10yr old laptop.

Intel Management Engine - yeah, it can be stripped too.

Resale value: Nominal, 5yr old macbooks are going to be steady for year 6-8. Personally I'm on the other side where I buy new macbooks and sell in 3 years for 70-80% of value, but it is different from "reliable." No, this is not saying buy a macbook, but financial side, and support side, it does make it easy.

tl;dr t420 good for it's time, but between a new SSD, max out the ram, replace wifi card if going to go loonix/arch puts you in over $300. If you go w/ a new LCD, yeah it goes overboard quick. Didn't even cover battery, and chinese shit.

i can vouch that upgrading a t420 for modern usage will put OP above the $500 mark which makes this model less sensible than a newer model for the same price. i upgraded my t420 with SSD + bigger battery + FHD panel + chinese LCD controller. also my C key got broken so i had to buy a replacement key (just the single key!) for $2 + shipping. in hindsight, i should have bought an entire keyboard for future use, but i didn't because i'm retarded. if another key goes, i'll just replace the board.

i actually daily drive a thinkpad x1 extreme gen 2 though, plugged into a dock with an external keyboard + mouse + monitor. desktop replacement life is pretty good, except my x1's battery life is like ~2hr and that's it... well maybe i could get more if i turn the GPU off in bios. but i don't travel so i haven't really had to do that. battery life on the t420 is actually pretty usable at ~6hrs (with the extended battery that sicks out the back for extra grip)

i'm curious to try a newer thinkpad T-series though, like a 450 or 470 or something. not sure. i think the RAM started getting soldered in the 480 series if i'm not mistaken so i'm assmad about that.
