Rušenje zidova apstrakcije

Predgovor: Rušenje zidova apstrakcije
Svet modernog inženjeringa nalazi se u neobičnom paradoksu. Programeri danas pišu kompleksne enterprise aplikacije, optimizuju storage engine sisteme i rukuju gigantskim bazama podataka, dok istovremeno sve manje razumeju na čemu se taj softver zapravo izvršava. Silicijum je postao apstrakcija skrivena iza bezbrojnih slojeva operativnih sistema, kompajlera i virtuelnih mašina. Kada softver uspori, moderni programer prečesto reaguje pukim dodavanjem hardverskih resursa u cloudu, umesto da razume gde procesor troši prazne taktove.
Ova knjiga je nastala kao radikalan odgovor na tu iluziju automatizma.
Ono što je započelo kao serija dinamičnih, beskompromisnih inženjerskih dijaloga između praktičara i veštačke inteligencije (Gemini AI), preraslo je u sveobuhvatan manifest računarske arhitekture. Naš cilj nije bio da napišemo još jedan suvoparan školski udžbenik koji prepisuje definicije iz prošlog veka. Cilj je bio da izgradimo čvrste, jasne konceptualne mostove između bazičnog 8-bitnog mikrokontrolera Intel 8051 i modernih višejezgarnih procesora.
Zašto baš 8051? Zato što na nivou ovog legendarnog čipa nema magije. Nema operativnog sistema da vam oduzme vreme usred petlje, nema keš memorije da sakrije kašnjenje RAM-a. Sve je ogoljeno do samog silicijuma. Kada kroz ove stranice savladate kako se ručno lažira stek za paralelne niti, kako se bitovi u PSW registru okreću u jednom mašinskom ciklusu i kako tajmer preuzima ulogu preemptivnog scheduler-a, vi ne učite zastarelu tehnologiju — vi učite fundamentalne zakone računanja.
Kada jednom shvatite da je moderni x86 procesor zaprazio samo CISC fasada koja u svom srcu krije RISC mašinu, i kada uočite zašto merenje performansi standardnom štopericom pada pod uticaj termodinamičke ezoterije, vaš pogled na softver se trajno menja. Prestajete da budete samo korisnik sintakse i postajete arhitekta sistema.
Zahvaljujem se AI Gemini na dijalogu — zaista sam impresioniran na koji način AI može da vam pomogne kod učenja i diskutovanja o temi. On je pravi asistent, odličan za spremanje ispita, sposoban da obradi ogromnu količinu informacija iz javne hardverske dokumentacije koju mnogi nikada nisu ni pogledali. Sve što treba je postaviti pravo pitanje.
Ova knjiga je izdata pod open-source licencom i u potpunosti pripada zajednici inženjera, studenata i entuzijasta okupljenih oko platforme zilsel-invent.com. Znanje ne sme da ima barijere. Spustite se sa nama na nivo registara, jer na samom dnu, granica između hardvera i softvera ne postoji — sve je samo matrica stanja.
Posvećeno mom Psu - mojoj Ptici, koju sam morao da uspavam i mom Atlasu papagaju koji me kljuca u prste baš u trenucima dok pišem sve ovo...

Fake VC830L digital multimeter

Image
This article is intended to explain some bad things about cheap digital multimeters since these devices are available in large quantities in Serbia. The key point of this article is security since cheap digital multimeters are not tested/produced according to standards. VC830L is one digital multimeter available in electronics distribution stores in Serbia, but we will avoid company names, since this article is more about “ pay attention before you buy ” cheap digital multimeter. The VC830L is about 10 euros, you cannot expect too much, but if you are not able to buy professional digital multimeter which costs over 100 euros, you will certainly buy the cheap one. Front mask: VC830L digital multimeter. The part interested for us is security so let see what we actually have regarding VC830L digital multimeter. It has three input connectors, starting from the left side: we have connector for 10 amps, common connector (COM) and the right one intended for voltage, r...

Electrolytic capacitors and design rules

Image
This article is in tended t o ex plain the bases about electrolytic capacitor , where t he y are used, basic construction, RLC circuit and much more. This is a fir st article about capacit ors and this article is based on zilsel-invent previous article about low pass filters at the following link : Low pass filter and voltage stabilization Electrolytic capacitors and design rules T he f igure #2 presents already used electrolytic capacitors. As we can see electrolytic capacitor is polarized device which means that it is important to pay attention during capacitor assembling to the PCB (printed circuit board). Depending on the capacitor manufactures, in some cases negative lead is marked with a negative sign , and in some cases positive lead (capacitor pin) is marked with a plus sign . Beside polarization mark, there are also labels about capacitance (for example 470 microfarads ) and maximum allowed voltage (for example 10V). The maximum allowed voltage is important parameter r...

How to design LM324 Astable Multivibrator

Image
This blog post is intended to describe how astable multivibrator works based on LM324 operational amplifier, RC timer and positive voltage divider circuits. This is one way to implement astable multivibrator since additional options are available like: specialized signal generators or 555 timer integrated circuit configured to work as an astable multivibrator . There are two states related to astable multivibrator based on RC timer or an analog timer (there is also a digital timer integrated into the microcontroller for example, but in general, digital timers are based on astable multivibrators implemented with quartz or resonator external oscillators, since digital timers count PWM /clock oscilations . Anyway, there are different types of astable multivibrators in order to provide clock cycles): charging and discharging. Charging   To describe charging state we will start from beginning with the completely discharged capacitor C (it has zero volts betwe...
