I am the author of Yummy, Pollen and Leaf. Pollen is the project I am currently working on and I am also writing the book Pollen: creating a secure portable assembler. Pollen is a programming language with XML syntax with support to modules that is designed to be a portable assembler like C, but secure and memory-safe.

Comics

Some type of kryptonite would probably be metal crystals in real life, causing symptoms similar to heavy metal poisoning but without actual heavy metals and without radioactive metals. Some types of strong industrial disinfectants have a formula similar to jadarite (or kryptonite), beyond having hydroxides in their formula which cause skin burns, irritation and immune system reactions such as inflamation.

Isochronic tones

Binaural and isochronic tones are capable of inducing emotions. You can try them by installing and using Android apps that play those sounds. They can be found on Google Play Store and FOSS app stores such as F-Droid.

Suggestibility

Suggestibility is the quality of being inclined to accept and act on the suggestions of others. Having much influence is great responsibility.

Simple nice behaviours such as quantizers on spoken and written languages may bring better life quality. Quantizers include adjectives and adverbs. Emojis play an important role on specifying feelings. As a fun fact, secret codes may be shared to specify numerical quantizers through mathematical rings.

Suggestibility can be applied in computer science and computer engineering in many ways. They are used by social media, news, and media apps to deliver and profit from ads. Suggestions and suggestibility in general can be found in the form of personalized content on the following locations:

• Android notifications;
• Windows notifications;
• popup balloons;
• social media feeds;
• video and audio streaming feeds;
• many others.

Therefore suggestions can be delivered contemporarily in a personalized way with the invention of the Web 2.0, as contrasted to the traditional media that included TV and radio.

1. Switch to a secure keyboards when programming and when saying or typing things that may not be very family friendly;
2. Verify that proper access to phone speakers and media speakers are set;
3. Verify that proper access to the microphones to avoid input data from ultrasound communications are set;
4. Verify that proper access on camera apps for image input readings;
5. Keep good contacts;
6. Take care of speakers in public places.

Try playing the Android Neko Easter eggs. Information can be hidden on the seeds from the operating system random number generator. The source code of the Easter eggs is open source. It can be used to debug informations coming from Google Play. Firewalls help, Google Play Services and modules developed for it run as a privileged system services. Different user apps such as WhatsApp can install different modules.

Havana Syndrome

Some people believe in aliens; some other people believe in other crazy stuff. It is normal to believe in something uncommon sometimes and humans don't necessarily all believe in the same things. There are different religions; different hobbies; different political positions; and so on. But if anyone asks me "what is your crazy belief?", I say "it's the Havana Syndrome". I always sleep with my head away from my bedroom window and the incidence of my headaches have been reduced considerably. Of course it is just a coincidence so this section of this Wikipage cannot be used as a reason to throw me in the mental hospital without a trial again.

Basically coils or antennas can be turned into a "coilguns" or Tesla coils.

"In the case of dopamine, a single absorption band occurs, with a central wavelength near 280 nm". Therefore, one may conclude that shinning strong electromagnetic or audio waves at specific frequencies may cause resonant effects on specific molecules on human brains, guts and other organs and those frequencies may be taken care of to cause no harmful health effects.

Android apps from malicious governments may have services that produce sounds at specific frequencies on the device speaker or headphone or there might be an external light or sound source outside the location an individual currently is.

Wi-Fi and Bluetooth MAC addresses may be used with radars to identify the location of an individual. The latest versions of the Android operating system randomize Wi-Fi MAC addresses for new connections by default, but they keep the same the same address if the device has been connected to an specific Wi-Fi access point before. The developer settings allow for the user to fully randomize the MAC address on each connection. The radar electromagnetic waves may also cause harmful health effects and discomfort.

There might be some sort of audio-to-light and light-to-audio transcoding so avoid any circuits that embed a strong light source with a semiconductor that might include a microphone. LED lights that do audio-to-light transcoding make a very high pitched sound that may only be audible by some young individuals with good sound listening capabilities.

The best way to avoid the Havana Effect is to:

1. Disable Bluetooth and location on the Android upper menu
2. Remove the SIM chip or enable Airplane mode
3. Uninstall apps that might be malicious (that may include apps made by unfriendly governments)
4. Revoke Phone permission on as many apps as possible as they may use the upper speaker (the one you use for Phone calls) to produce high pitch inaudible noise and they use the "call volume" audio mixer
5. Make sure there is no app running as a music player by looking on the Android upper menu as they may use the "media volume" audio mixer
6. Disable HW overlay and enable full MAC randomization on the developer settings on Android
7. Get rid of LED lights and use analog lights only
8. Get rid of RFID tags

Measurement of stimulus can be made by using sensors. Electromyography (EMG) measures muscle response or electrical activity in response to a nerve's stimulation of the muscle. Those can be used to mesure how well muscle and nerve implants -- such as those used on vagus nerve stimulation -- are responding to electromagnetic (radio, NFC, Bluetooth, Wi-Fi or 5G) waves.

Electromagnetic fields may affect the body neurotransmitters as well as the neurotransmitters of pets and other living beings and may contribute to have no insect and no viral infection. Most neurotransmitters have some resonant frequency.

Anti-fungals may be useful for small intestinal fungus overgrowth.

New technologies of bioluminescence and optogenetics are being developed. Bioluminescence is used by living beings for being identified in natural habitats.

Food with normal monosodium glutamate (MSG) levels, may contribute for having no migraines and no schizophrenia symptoms, and no bowel inflammation due to the normalized vasoactive properties of diamines and nitrates.

Monosodium glutamate can be found naturally in high amounts in food fermented by fungus or bacteria; seeds, nuts and beans, grains including soy; overcooked meat; foods containing nitrates such as processed meats; grapes, tomatoes, strawberries; mushrooms and fungus in general; and a little amount of MSG in starch vegetables such as corn and potatoes.

More information about vasoactive amines can be found in toxicology books.

Refresh rate

Some of the newer Android phones come with a feature called Adaptive Performance. It is essentially an AI that can control the CPU step and screen frame rate to save battery and avoid overheating. The problem is that people with epilepsy have a higher chance of having a seizure when looking at screens on a low frame rate (e.g. 60 fps is dangerous to them). The fact that Adaptive Performance constantly changes the frame rate according to an artificial intelligence algorithm and that frame rate may drop below 100 Hz, poses a danger to epileptic Android users when that feature is turned on.

D programming language

The D programming language is being used to write Pollen and Leaf.

The following snippet taken from the D wiki demonstrates how to allocate classes on the stack by using the scope keyword:

class C { ... }

scope c = new C();	// c is allocated on the stack
scope c2 = new C(5);    // allocated on stack
scope c3 = new(5) C();  // allocated by a custom allocator

The scope keyword can be used with the parameter storage classes and the @safe function attribute for assuring memory safety.

@safe int read(in char[] input, ref size_t count, out int errno);

Pointers are what make programming languageges insecure. The following code taken from the D blog demonstrates how to wrap C functions that take C pointers.

auto safeRead(int fd, ubyte[] buf) @trusted
{
    return read(fd, buf.ptr, buf.length);
}

Leaf takes advantage of the memory safeties given by D to create an operating system that is completely memory-safe except for small assembly stub functions that provide low-level hardware dependent functionality such as memory protection and system calls. Leaf is designed to run a Templatizer -- a web framework -- interpreter on a FPGAs -- which are usually free of hardware backdoors -- and also on microcontrollers for small web services. The I/O including disk storage is done by a data store node or database node. The network is based on packets through a serial interface. The serial interface uses interrupts to avoid polling. Leaf can be tested with qemu on a x86 machine. It is fully written in D and assembly using the memory-safe subset.

Rust programming language

Moving values in Rust is easier than borrowing mutable values because no split borrow is needed. Try it here.

struct MyFirstStruct {
    foo: u32,
}

struct MySecondStruct {
    bar: String,
}

fn my_function(mut a : MyFirstStruct, mut b : MySecondStruct) -> (MyFirstStruct, MySecondStruct)
{
    a.foo += 1;
    b.bar += "Moving values is easier than borrowing mutable values.\n";
    b.bar += "No split borrow needed!\n";
    (a, b)
}

fn main() {
    let s1 = MyFirstStruct {
        foo: 1,
    };
    let s2 = MySecondStruct {
        bar: "Hello, world!\n".to_string(),
    };
    let (s1, s2) = my_function(s1, s2);
    print!("{}", s2.bar);
    println!("1 + 1 = {}", s1.foo);
}

An example of "split move":

struct MyStruct {
    foo: MyField,
    bar: MyField,
}

struct MyField {
    value : u8,
}

fn my_function(mut a : MyField, mut b : MyField) -> MyStruct
{
    a.value += 2;
    b.value += 2;
    MyStruct {
        foo: a,
        bar: b,
    }
}

fn main() {
    let s1 = MyStruct {
        foo: MyField {
            value: 1,
        },
        bar: MyField {
            value: 2,
        },
    };
    let s2 = my_function(s1.foo, s1.bar);
    println!("{} {}", s2.foo.value, s2.bar.value);
}
