The Dongfeng (simplified Chinese: 东风; traditional Chinese: 東風; lit. 'East Wind') series, typically abbreviated as "DF missiles", are a family of short, medium, intermediate-range and intercontinental ballistic missiles operated by the Chinese People's Liberation Army Rocket Force (formerly the Second Artillery Corps).

History

In the early years of New China, the industrial development of China mainly depended upon capital investment and technical assistance. At that period, China exchanged through foreign trade at equal values for “156 types” of Soviet industrial project assistance, with building nuclear bombs and missile factories and corresponding technologies included.

Chinese missile production started from imitating Soviet missiles. At the end of 1957, Soviet provided China with two P-1 missile models, and in June, 1958, the first batch of drawings and technical documentation of P-2 missiles was transferred. Scientists and engineers formed the Fifth Institute of National Defense Ministry (hereinafter called “the Fifth Institute”) , translated and copied those documents and made preparation for imitating the “1059”model missile.

“1059” was named for paying homage to 10th anniversary of the founding of New China of October 1, 1959. Under the lead of Qian Xuesen, scientists and engineers gained a thorough grasp of design theories, overcame technical obstacles and managed to advance imitations of Soviet missiles.

While the whole Fifth Institute was quietly getting immersed in hard work, the Sino-Soviet relationship suddenly cooled down and the “honeymoon period” of the two nations came to end. In June, 1956, the Soviets began to tear up the “Sino-Soviet New National Defense Technology Agreement”, and withdrew all the Soviet experts in the next year and abolished all the joint projects.

Although that following serious and tough situation fell upon the shoulders of Qian Xuesen, his confidence, self-improvement and self-esteem once again showed their power. During several round-table meetings, Qian Xuesen called upon all the personnel in the Fifth Institute with great passion not to give up or hold back, and to carry on the imitation of missiles. Qian stated,

“All of us in the Fifth Institute would certainly get straight and upright under the pressure of the fact that Soviet experts were withdrawn. We are able to build our own missile mission with our best efforts, and the Soviets cannot overwhelm us!”

“We shall continue our work day and night; we shall burn the candles at both ends!”

“We will certainly catch up with progress!”

Just like that, inspired by Qian Xuesen’s passion and inspiration, all comrade fellows bent their efforts towards only one direction, held their breath and swore to launch the “1059”missile to the sky.

At 9:00 am, under the command of chief officer, “1059”missile rose to sky, and hit the target exactly within the proposed impact area at the distance of 554km from the launch site after flying for 7 minutes and 37 seconds.

This “missile of our own”- “1059”was named for “Dongfeng 1”, DF-1 for short. From then on, Qian Xuesen led the Fifth Institute to succeed in improving and designing the “Dongfeng 2 and Dongfeng 3” missiles by ourselves and Dongfeng missile family were expanded and gradually grew up to be the champion weapons of our national defense mission. “Dongfeng 31-A model” nuclear missile attending our 60th anniversary military parade of the New China on the 2009 National Day was the strong new member of the Dongfeng missile family.

On October 16, 1964, the first atomic bomb exploded in China and the rising mushroom cloud astonished the world.

However, this atomic bomb was detonated by fixing it upon an iron cradle in advance, which caused western media to state it was “only a bomb without a gun” to satirize China, faced with the reality that, although atomic bomb had been produced, it still could not be discharged.

How to change that situation?

Undoubtedly, missile is the best “gun”. Qian Xuesen proposed to develop nuclear missiles carrying nuclear warheads on the basis of successful test launches of mid-and-short-range missiles, and that is the well-known pioneering work of “combination of missile and atomic bomb” at the present time.

Nuclear missiles are very different from typical ones. A subtle mistake could incur irreparable losses. Qian Xuesen led the Fifth Institute to make improvements for the “Dongfeng 2”missile. All the comrades worked hard and took every detail quite seriously and carefully.

On October 26, 1966, Marhshal Nie Rongzhen and Qian Xuesen came to the site to personally monitor the docking process of the “DF-2A”missile body and atomic warhead.

On the site, a young technician named Tian Xiankun took charge of that docking task. Given that the distance between the warhead and missile body was just longer than one foot, only by moving their bodies sideways could they go there. However, despite the narrow space, Tian Xiankun finished more than a hundred movements with perfect accuracy through his highly skilled technologies and tools, and succeeded in docking warheads and missile bodies just like doing embroidery on cloth.

On October 27, 9:00 am, Tong Lianjie, one of the seven operators pressed the button of the principal machine of the control platform, and China’s first nuclear missile slowly rose and flew to the sky with a roaring boom.

However, the control room fell into quiet after the missile taking off, and no one could dare take a heavy breath. In their eyes, the nine minutes of estimated flight time seemed endless.

At last, Lop Nur testing ground delivered a report,stating: the nuclear missile hit the target exactly and the nuclear explosion smoothly took place!

That moment was so valuable and delightful! The seven operators in the underground control room could not help but shed tears of joy…

To celebrate that great and historic moment, and learning we were prepared to build the Qian Xuesen Library, the Second Artillery Force of the PLA donated to our library a missile with the same model as the “DF-2A”nuclear missile , and allowed us to use it as a large-scale physical subject exhibit in the Library. On March 27, 2011, under witness of the public, military officers and soldiers together with the construction company managed to unload the missile and then hoisted it to move from roof to rotunda, which took 45 minutes to complete the whole lift and set-up process.

The most glorious and most dangerous moments condensed into extraordinary, historic, and frozen time, which silently says, the peaceful time and life today we have derive from the endless efforts of Qian Xuesen and others in very tough environment.

@[email protected] RE: Nuclear reactor simulator game

Sorry for late reply, I'm always doing that to people and I hate it :/

Yess, there are a few, precious, rare nuclear reactor sim games, which vary in quality and complexity quite a bit. The one I was referring to is "Chernobyl: The Legacy Continues", which has a very weird history for a game lol. It was made as an actual plant operator training simulator program but was turned into a game for total fuckin nerds lol. I don't wanna put anyone off of trying it but it's probably the most complicated to learn and master out of the reactor sim games I know of, has a learning curve like a mountain and UI like you would imagine for a 90s industrial training program but it is really fun if you can get into it and is like no other game I know of lol. It's also an ancient game for 16-bit Windows but someone has made a modern port of it here: https://github.com/gdzx/chernobyl-simulator (that port also fixes some bugs and lets you pause and turn off the pop-up videos of the plant supervisor telling you off for messing up lmao)

If you're on Unix you might be able to run that with Wine without the included NTVDM compatibility layer (also ported to modern Windows), I'm not sure. Would highly highly recommend checking out this guy's videos about the game to learn how to play cuz the in-game tutorial does not prepare you lol, also the videos are just fun to watch (he even has a Chernobyl accident recreation video): https://www.youtube.com/playlist?list=PLtMqEBTig8fJzthGYTWWWuMYIB1z3nhJX (scroll down to RBMK-1000 simulator tutorials)

Probably my other favorite reactor sim game is called "Nucleares", it's much much more modern and simulates the operation of the whole plant in 3D. It's simplified but still really fun and much more easy to get into. I think it's still in early access and has some frustrating qualities but it's getting better and better. Also, tbh, that game kept my shattered attention span for much longer than Chernobyl lol

There are a few other reactor sim games floating around, but not enough imo :/ . I tried another called something like "BWR Reactor Simulator" but it kinda just felt like a tech demo or something for a real simulator program, kinda boring, too simple.

Hope you find interesting, lemme know if you need help getting anything to run, simulated plant equipment or otherwise lol. That modern port of Chernobyl ran pretty well on my system but it's ancient, couldn't get the UI to scale so it's kinda harsh on the eyes on modern resolution screens too :(

Simgenics needs to turn another one of their training programs into games for us reactor nerds smh

My lovely Dr. Partner painted my nails for me last night and they look so good! parrot-vibin We went with orange and black so I look all spoopy, and it really suits me (or at least my current mood) quite well

My partner's kidneys has gotten worse and are moving into dialysis/transplantation territory. We are going on a planned family trip over the weekend, trying to act normal for the kids, and then they have to go straight to the hospital Monday morning.

They were about to die from kidney failure a couple of years ago. Their kidney function was down to 4% due to a bunch of idiot GP's doing their best to turn a combination of kidney stones and a simple UTI into a lethal cocktail through their arrogance and incompetence. It was so bad they had resuscitation equipment rolled up right outside the room at the hospital.

My partner is afraid. The kids are afraid. I'm afraid and stressed and tired and angry and I feel guilty for being so affected by all of this instead of being supportive.

[–] [email protected] 5 points 2 hours ago

My dad is going through dialysis and it's brutal, especially since it seems like a transplant is not an option for him. I'm sorry for you, your partner and the rest of your family.

Just try to tell yourself that giving whatever you can counts for twice as much when you're this weighted down. That's what I do for myself, anyway. It at least helps suppress guilty thoughts a little.

[–] [email protected] 5 points 2 hours ago* (last edited 1 hour ago)

I wish your partner all the best and I am sorry for the struggle you're going thru. Danish doctors can be really shit, it's like they have a genius complex or something.
Had to argue with one whom wanted to release my partner who had 8/10 paralyzing pain in their abdomen. The doctor wanted to release them because he couldn't figure out what was wrong, which obviously meant that nothing was wrong then. I hope you are past the "having to argue" faze and I hope it goes smooth from here-on out.

Holy fuck how do I KEEP forgetting that no matter how confident I am that what I have to say will resonate, it is NEVER worth posting on reddit-logo

I need to repeat a mantra to myself or something: No matter how reasonable you are, no matter what you have to say, they WILL miss your point and drag you down for it.

Got hit with a high energy day yesterday, so high and powerful I felt like I overdosed cocaine. ADHD is fucking weird man.

Fr, what the hell is up with that

I feel like new meds leveling me out a bit but still

I start doing a bunch of stuff I put off, post a lot or work on a project or something, then all the momentum is gone the next day lol

@[email protected] have you ever tried a Neti Pot? I have had relief from those symptoms using one.

Sterelize the water before using, though.

Hey y'all remember when there was a civil war in Michoacan? Nobody except 4channers really talked about it, it's super weird how it just got completely buried. I lived in a state next to it at the time and remember everyone talking about - Though mainly because the price of lime skyrocketed. Kid in my school who used to be dirt poor showed up wearing gucci one day (his dad was a lime farmer).

This year they released a direct-to-digital animated adaptation of Watchmen, in two parts. Part two doesn't come out until November. But I paid the five dollars to watch part 1. It was good, voice acting was great, the animation style was a little odd but it worked. But it was an extremely faithful adaptation. They even included the pirate comic-book-within-a-comic-book interludes. On one hand Watchmen is one of the greatest comic books ever made and it deserves a better adaptation than Zack Snyder gave it (though I do kinda like Snyder's movie anyway), so a faithful adaptation is nothing to complain about. On the other hand, after I got done watching it I sorta felt like I could've just read my copy of Watchmen rather than paying five dollars to see it in an animated form. I think ultimately the art direction and voice acting add enough that I don't regret it and will probably rent part 2 when it comes out, but I can't quite shake the feeling I would've been better served by doing a re-read.

thread was locked before i could reply but yeah i do agree that the beginning of yorknew where kurapika is in the mansion and gon and killua are trying to scrap together money is kind of a lull in the story but once it kicks into gear it's just nonstop. Honestly i think the phantom troupe's one of my favorite antagonists, they all have interesting dynamics between each other and personalities that make them entertaining to see. Their origin story is also very well done but that comes way later in the manga.
