@BradeskoUrban @sidefx This is the kind of thing that brings me back to nVidia tech demos of my youth (like GeForce, GeForce 256 here) where you just go "wowww". Wow. This is so cool. I've always thought programmable effects were way cooler than "fidelity" / "photorealism". Show me cool shit! 👍🍻

![Many say that the catastrophic fires ravaging Los Angeles weren’t the fault of Governor Gavin Newsom and LA Mayor Karen Bass. Fires are inevitable in Los Angeles, and the water ran out because no water system could withstand that many fires simultaneously, they add. But LA firefighters themselves disagree. They say the reason they arrived too late to stop the fires from becoming catastrophic was because of severe budget cuts. The Fire Department did not pre-deploy fire engines to strategic locations, and helicopters arrived half an hour too late to put out the Palisades. “That [Santa Ynez] reservoir being closed did not allow helicopters to drop and suck water up from five minutes away,” a new firefighter whistleblower, the third who has come forward, told me. “Instead, they had to fly 10 to 15 minutes away to go get water somewhere else.” The problem is that the LA Fire Department is one of the most severely understaffed of America’s 10 largest cities. It has less than a single firefighter per 1,000 residents compared to Chicago, Dallas, and Houston, which have twice as many. “ In 1960, our city population was 2.5 million, and we had 112 fire stations. In 2020, our city population was 3.9 million, and we had 106 stations,” a representative of LA’s firefighters ’ union testified last month. “That's 1.4 million more people and six fewer fire stations.” This undermines the Department’s ability to respond to emergencies. “In 2020, the average emergency response time was seven minutes and 53 seconds, nearly double the NFPA recommendation.” Part of the problem is that the number of homeless fires in LA doubled between 2020 and 2023 to an astonishing 38 per day. They start dangerous fires in many ways, including by breaking through the sidewalk into the city’s electrical system, which can result in explosions and death. Still, many say, it is wrong to blame homelessness for LA’s fires. They are victims of trauma and poverty. But the research is unequivocal. Over half of all fires that the LA Fire Department responds to are set by a homeless person. "There were two huge explosions, and when I looked out my apartment window, I saw plumes of black smoke," a resident told NBC-Los Angeles. "People are literally dying in the streets, in tents burning down around them.” And the evidence is clear: leaving homeless people on the street makes them three times more likely to die than people required to come inside to sleep in shelters. The third firefighter whistleblower says the firefighters are being put in danger by budget cuts. “Even last week,” the person said, “I wanted to work and I was told, ‘Sorry dude, we don't have a seat for you to fill because there's not enough apparatuses,’” meaning fire engines or other equipment. One hundred fire engines and other apparatus are currently out of service because the city cut the Fire Department’s budget, and it couldn’t afford to hire mechanics to fix equipment. “We have a crack about halfway down our water tank. Half of our [engines and other] apparatuses are broken. They were sending rookies, new probationary firefighters, out to the field last year with no department-required brush jackets.” The firefighters lack life-saving equipment. “We were running out of electrodes to do EKGs,” the person said. “We've been running out of gloves. We've been running out of drugs, you name it. There's been ambulances that have been having to steal stuff or borrow stuff from the hospitals just to stay available.” At the meeting last month, the president of the city’s firefighters union warned, “If we cut one position, if we close one station… the residents of Los Angeles are going to pay the ultimate sacrifice, and someone will die.” All this and yet Los Angeles is one of the richest cities in the world. Eighty-four of America’s richest 400 people live in California, and LA is home to 26 billionaires who collectively possess a net worth of approximately $185 billion. “It kills us when we see holes in the system,” said the whistleblower, “and we aren’t able to do the job we expect of ourselves, and if we had the appropriate resources and staffing, I don’t think any of the fires were inevitable. I know for a fact it would not be what it is. We saw my particular fire engine in maintenance for a year and a half.” Some politicians are demanding reform. ”There are large swaths of the city with no emergency response resources available,” said Councilmember Traci Park, who urged more funding for firefighting last year. “ I think that people are rightly upset, not only that this happened, but there is a sense that we as local leaders needed to do more for them. I feel like I let them down, and I've been screaming about it from the day I came in.” As such, the problem is not poverty, it is severe mismanagement and bad governance. Not only is the city’s mismanagement to blame for LA’s disastrous response to the fire, but it’s also responsible for the city’s ongoing homelessness disaster. Why is that? Part of the reason is the city’s Diversity, Equity, Inclusion (DEI) programs. “The city will only purchase from vendors that support DEI,” said the firefighter. “So we'll go with a vendor that we have to pay twice as much, or the shipment may take twice as long, in order for it to be a DEI vendor rather than the vendor who has it at half the price and can get it to us tomorrow.” The whistleblower said that DEI programs put firefighters and the public in danger. “I personally witnessed in my own drill tower them making and passing women just to get their [female quota] numbers even though they didn't have to meet all the criteria the men did....” Please subscribe now to support Public's award-winning investigative reporting, read the rest of the article, and watch the rest of the video!](https://image.24vids.com/tw-1880013540263669983/ext_tw_video_thumb/1880013066298920960/pu/img/4S5OELKUDJnLYewl.jpg)
![U-Net by hand ✍️ ~ 17 steps walkthrough below I consider U-Net as a key milestone in deep learning, the first image-to-image model that really worked! It came out of medical imaging, an unusual place, not from NeurIPS or CVPR or ACL. Now it is the backbone of diffusion models, which you see in almost all modern image generation models. I drew the network as a C so the matrix multiplication flows naturally down. Tilt your head to the right and it is a U again. 🤣 Goal: push a 3 x 16 image down to a 2 x 4 bottleneck and back out again, filling in every cell yourself. = 1. Given = An image of three channels, R, G and B, sixteen pixels wide, and every kernel the network will use. = 2. Convolution 1 = Let us slide the first kernel over the image. Each output is one multiply-and-add over a 2 x 3 window, and the result is the green feature map. = 3. Find the maxima = We circle the largest value in each 1 x 2 window. Circling first is worth the extra step: it is the pooling decision, made before anything is written down. = 4. Max pool 1 = Let us copy those maxima down. Sixteen columns become eight, and half the detail is gone for good. = 5. Convolution 2 = We convolve again with the second kernel, deeper into the contracting path. The feature map is blue now. = 6. Find the maxima again = Same move as step 3, on the blue map. = 7. Max pool 2 = Eight columns become four. = 8. The bottleneck = Let us convolve once more. This is the bottom of the U, a 2 x 4 block that is everything the network kept. = 9. Spread it out = We start back up. The transposed convolution writes each bottleneck value into a wider grid, leaving gaps between them. = 10. Transposed convolution 1 = Let us fill those gaps by convolving over the spread-out grid. Four columns become eight. = 11. The first skip = We copy the encoder's matching row straight across. This is the skip connection, and it is the whole reason a U-Net can recover detail that pooling threw away. = 12. Convolution with the skip = Let us convolve the upsampled features together with the copied ones. = 13. Spread it out again = Same as step 9, one level up. = 14. Transposed convolution 2 = Eight columns become sixteen, back to the width we started at. = 15. The second skip = The encoder's first feature map comes across, the one made before any pooling happened. = 16. Convolution and ReLU = We convolve, then cross out every negative and set it to zero. = 17. Output convolution = Let us apply the last kernel. Out comes R', G' and B', an image the same size as the one we started with. The outputs: R' = [3, 0, 7, 0, 7, 0, 17, 0, 3, 0, 9, 0, 2, 0, 6, 0] G' = [1, 20, 1, 10, 1, 12, 1, 19, 2, 5, 1, 11, 1, 3, 1, 7] B' = [4, 20, 8, 10, 8, 12, 18, 19, 5, 5, 10, 11, 3, 3, 7, 7] Congrats!

![Islamic Art of War By: Ofer Binshtok Islam wages a continuous global war through various methods and with varying intensity against non-Muslims 24/7, as commanded by the Quran and Muhammad, a war that has persisted for approximately 1400 years and will continue indefinitely. In places where non-Muslims grow weary of conflict and seek peace, avoiding confrontation and attempting to appease Islam, believing they have achieved tranquility through signing agreements with Islam and even allowing its migration into their territories, during this time, Islam builds its strength and attacks them when it senses it has the upper hand, from within and from outside, in the most brutal way possible. This war strategy relies on the Islamic Art of War, based on the Quran and Muhammad's Sunnah. Quran 8:39 - The goal: a world containing only Muslims through war. Quran 98:6 - Demonization of non-Muslims. Quran 3:28 - Deceive non-Muslims. Quran 47:35 - Do not seek peace when you have the upper hand. In other words, attack. Quran 8:60 - During a hudna (ceasefire), Islam prepares for war. Quran 9:123 - Attack nearby non-Muslims. Quran 9:5 - Kill every non-Muslim in the world. In 622 AD, Muhammad migrated from Mecca to the settlement of Medina (Yathrib) in the Arabian Peninsula, where he was received as a refugee by the Jews who had established and controlled the prosperous region, granting him shelter. Within approximately eight years, after building his strength, Muhammad eliminated the presence of Jews and other non-Muslims in the area. In 628 AD, Muhammad signed a ten-year hudna (truce) agreement in Hudaibiya with the Quraysh tribe of Mecca, as his forces were weaker than theirs. In 630 AD, when his power was sufficiently strong, he violated the agreement with the Quraysh, attacked Mecca, conquered it with ease, and eradicated all other cultures present there. Muhammad's Sunnah, which is binding in Islam according to Quran 33:21, commands every Muslim to emulate all of Muhammad’s words and deeds, which are considered sacred. ---- "A Muslim must be loyal only to the Islamic Ummah" By: Ofer Binshtok The identity of the Muslim is solely to be a part of the global Islamic Ummah, without any connection to a nation-state or to another culture that is not the Islamic Ummah. The idea of independent Islamic nation-states contradicts the Islamic idea as it is found in the Quran and Muhammad's Sunnah. A Muslim, wherever he is in the world, is part of the Islamic Ummah. A Ummah that should be ruled by a caliph through Sharia law. Islam is a global political-religious worldview of a world without borders. The existing Islamic nation-states are actually an act of heresy. A disbeliever who converts to Islam must completely break away from his former identity, become part of the Islamic Ummah, and serve its purposes personally. Every Muslim, wherever he is, is personally obligated to act so that the Islamic Ummah will be established—that is to say, to collapse every nation-state that exists in the world so that the Islamic Ummah will replace it. The fact that the idea of Ummah is included in the central motif of the Quran is evidence of the vital significance of this concept. In Islamic terminology, the term "Ummah" refers to the religious community, also known as the Islamic holy community. This is the primary interpretation of the phrase found in the Quran. Quran 5.51: "O you who believe! Take not the Jews and the Christians as Auliyâ’ (friends, protectors, helpers), they are but Auliyâ’ of each other. And if any amongst you takes them (as Auliyâ’), then surely he is one of them. Verily, Allâh guides not those people who are the Zâlimûn (polytheists and wrong-doers and unjust)." Quran 2.143 "Thus, have We made of you an Ummat justly balanced, that ye might be witnesses over the nations, and the Messenger a witness over yourselves; and We appointed the Qibla to which thou wast used, only to test those who followed the Messenger from those who would turn on their heels (From the Faith). Indeed it was (A change) momentous, except to those guided by Allah. And never would Allah Make your faith of no effect. For Allah is to all people Most surely full of kindness, Most Merciful." Quran 3.104 "Let there be one nation of you, calling to good, and bidding to honour, and forbidding dishonour; those are the prosperers." Quran 3.110 "You are the best nation produced [as an example] for mankind. You enjoin what is right and forbid what is wrong and believe in Allah. If only the People of the Scripture had believed, it would have been better for them. Among them are believers, but most of them are defiantly disobedient." Quran 16.92 "And be not like her who undoes the thread which she has spun after it has become strong, by taking your oaths a means of deception among yourselves, lest a nation may be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfills Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad SAW which the disbeliever denies it and that was their difference amongst them in the life of this world]." Tafsir Al-Qurtubi, volume 1, page 649: Muhammad said, "The earth was made a mosque for me." Sahih al-Bukhari, 3167: "The Prophet said, "If you embrace Islam, you will be safe. You should know that the earth belongs to Allah and His Apostle." --- "Because Muhammad admitted to using terrorism, committing an act of terrorism is considered as a holy deed in Islam."

Sahih Al-B ukhari\ translated by Muhammad Muhsin Khan.- Riyadh. Volume 4. (122) CHAPTER. (56 - THE BOOK OF JIHAD) (Fighting for Allah's Cause) Page – 140. Quran 68.4 And indeed, you are (Muhammad) of a great moral character. Quran 33.21 "Indeed in the Messenger of Allâh (Muhammad (صلى الله عليه وسلم you have a good example to follow for him who hopes for (the Meeting with) Allâh and the Last Day, and remembers Allâh much." --- "When a Muslim looks at a non-Muslim, the Quran creates a lens for him through which he sees and understands the non-Muslim, composed of these three verses (and there are many more):" 8:55, 98:6, and 9:28. Verses 8:55 and 98:6 portray non-Muslims as the worst creatures, even worse than cockroaches, bedbugs, and ticks. Verse 9:28 portrays non-Muslims as physically and spiritually filthy, akin to the filth of excrement. In summary: When a Muslim looks at a non-Muslim, he sees him through the lens of the Quran as the worst creatures, worse than cockroaches and ticks, and physically and spiritually filthy to the level of excrement. Quran 8.55 “Verily, The worst of moving (living) creatures before Allâh are those who disbelieve, - so they shall not believe.” Quran 98.6: "Verily, those who disbelieve (in the religion of Islâm, the Qur’ân and Prophet Muhammad صلى الله عليه وسلم) from among the people of the Scripture (Jews and Christians) and Al-Mushrikûn will abide in the Fire of Hell. They are the worst of creatures." Quran 9.28: “O you who believe (in Allâh’s Oneness and in His Messenger Muhammad!) Verily, the Mushrikûn (polytheists, pagans, idolaters, disbelievers in the Oneness of Allâh, and in the Message of Muhammad) are Najasun (impure). [1] So let them not come near Al-Masjidal-Harâm (at Makkah) after this year; and if you fear poverty, Allâh will enrich you if He wills, out of His Bounty. Surely, Allâh is All-Knowing, All-Wise.” (V.9:28) Their impurity is spiritual and physical: spiritual, because they don’t believe in Allâh’s Oneness and in His Prophet Muhammad; and physical, because they lack personal hygiene (filthy as regards urine, stools and blood). And the word Najas is used only for those persons who have spiritual impurity e.g. Al-Mushrikûn. Quran 9.14 "Fight against them so that Allâh will punish them by your hands and disgrace them and give you victory over them and heal the breasts of a believing people." Quran 8.39: "...fight them until disbelief (non-Muslims) disappears and the whole Dean (way of life) is for Allah alone...(for Islam)” Quran 9.5: “...kill the Mushrikun (non-Muslims) wherever you find them…" Al-Bukhari: "To wage war against Allah means to reject faith in Him." Quran 2.191: "The sin of disbelief in Allah is greater than committing murder." --- "The concept of Jihad as defined by Sharia law." By: Ofer binshtok. 09.0 JIHAD (0: Jihad means to war against non-Muslims, and is etymologically derived from the word mujahada, signifying warfare to establish the religion. And it is the lesser jihad. As for the greater jihad, it is spiritual warfare against the lower self (nafs), which is why the Prophet (Allah bless him and give him peace) said as he was returning from jihad, "We have returned from the lesser jihad to the greater jihad." The scriptural basis for jihad, prior to scholarly consensus (def: b7) is such Koranic verses as: (1) "Fighting is prescribed for you" (Koran 2:216); (2) "Slay them wherever you find them" (Koran 4:89); (3) "Fight the idolators utterly" (Koran 9:36); and such hadiths as the one related by Bukhari and Muslim that the Prophet (Allah bless him and give him peace) said: "I have been commanded to fight people until they testify that there is no god but Allah and that Muhammad is the Messenger of Allah, and perform the prayer, and pay zakat. If they say it, they have saved their blood and possessions from me, except for the rights of Islam over them. And their final reckoning is with Allah"; and the hadith reported by Muslim, "To go forth in the morning or evening to fight in the path of Allah is better than the whole world and everything in it." Details concerning jihad are found in the accounts of the military expeditions of the Prophet (Allah bless him and give him peace), including his own martial forays and those on which he dispatched others. The former consist of the ones he personally attended, some twenty seven (others say twenty-nine) of them. He fought in eight of them, and killed only one person with his noble hand, Ubayy ibn Khalaf, at the battle of Uhud. On the latter expeditions he sent others to fight. himself remaining at Medina, and these were forty-seven in number.) THE OBLIGATORY CHARACTER OF JIHAD 09.1 Jihad is a communal obligation (def: c3.2). When enough people perform it to successfully accomplish it, it is no longer obligatory upon others (0: the evidence for which is the Prophet's saying (Allah bless him and give him peace), "He who provides the equipment for a soldier in jihad has himself performed jihad," and Allah Most High having said: "Those of the believers who are unhurt but sit behind are not equal to those who fight in Allah's path with their property and lives. Allah has preferred those who fight with their property and lives a whole degree above those who sit behind. And to each. Allah has promised great good" (Koran 4:95). If none of those concerned perform jihad, and it does not happen at all, then everyone who is aware that it is obligatory is guilty of sin, if there was a possibility of having performed it. In the time of the Prophet (Allah bless him and give him peace) jihad was a communal obligation after his emigration (hijra) to Medina. As for subsequent times, there are two possible states in respect to non-Muslims. The first is when they are in their own countries, in which case jihad (def: 09.8) is a communal obligation, and this is what our author is speaking of when he says, "Jihad is a communal obligation," meaning upon the Muslims each year. The second state is when non-Muslims invade a Muslim country or near to one, in which case jihad is personally obligatory (def: c3.2) upon the inhabitants of that country, who must repel the non-Muslims with whatever they can). 09.2 jihad is personally obligatory upon all 'those present in the battle lines (A: and to flee is an enormity (dis: pH)) (0: provided one is able to fight. If unable, because of illness or the death of one's mount when not able to fight on foot, or because one no longer has a weapon, then one may leave. One may also leave if the opposing non-Muslim army is more than twice the size of the Muslim force). 09.3 Jihad is also (0: personally) obligatory for everyone (0: able to perform it, male or female, old or young) when the enemy has surrounded the Muslims (0: on every side, having entered our territory, even if the land consists of ruins, wilderness, or mountains, for non-Muslim forces entering Muslim lands is a weighty matter that cannot be ignored, but must be met with effort and struggle to repel them by every possible means. All of which is if conditions permit gathering (A: the above-mentioned) people, provisioning them, and readying them for war. If conditions do not permit this, as when the enemy has overrun the Muslims such that they are unable to provision or prepare themselves for war, then whoever is found by a non-Muslim and knows he will be killed if captured is obliged to defend himself in whatever way possible. But if not certain that he will be killed, meaning that he might or might not be, as when he might merely be taken captive, and he knows he will be killed if he does not surrender, then he may either surrender or fight. A woman too has a choice between fighting or surrendering if she is certain that she will not be subjected to lin indecent act if captured. If uncertain that she will be safe from such an act, she is obliged to fight, and surrender is not permissible). Source: Reliance of the Traveller - Revised Edition.
