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in the Fifth Institute would certainly get straight and upright under the pressure of the fact that Soviet experts were withdrawn.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.

Me, genuinely asking myself as I wake up with a headache after two days in a row of 10+ hour long days delivering amazon treats:

"Is once a month too often a frequency to call in sick?"

I did. Yesterday I had a headache for like 6 hours during my day and I woke up with it this morning. Delivery driving with a headache is miserable.

@[email protected] hot sauce is done! Fresno/garlic is super yummy, habanero/ginger has way too much ginger and is more of an overpowering punch to the face, even if I like the spice level more. Gonna use those notes and try to hone in for the next batch, whenever I get started! sauce-boss

[–] [email protected] 4 points 1 day ago (1 children)

Decent results! Hopeful the ginger can be toned down in the next batch c: Keep me posted! ayeaye

it's me again, with another rant

Weather Stripping.Holy fuck I hate this stuff. You go to the house store, and you look at like 50 different options for the bottom of your door, and you realize that you need to know exactly how many atoms wide your damn front door is if you want good clearance, ok that one's on me.

But then you see the kind you got last year and you think to yourself "that one never really worked that well and it kinda started falling apart pretty quick" so you decide to take a chance and get one that looks like it might last a bit longer. You know you'll have to cut it to length anyway, since that's what you do with stripping.

So you finally get around to trying to install it, it's cold, it smells like allergies outside, and despite the fact that the base of the stripping you bought matches the depth of your door (thank fuck) AND the width appears to match too, you still have to hammer it on because it's very tight. And since your partner is busy making breakfast because you insisted on doing this by yourself so you could "get it out of the way" you struggle. And... well, turns out it's too wide. It's really hard to get on, and get off, and so now you're trying to use fucking garden shears to cut this thing to length...

Apparently, the correct tool for this is a hacksaw. Every year we do this, we forget to get a hacksaw. So I use garden shears. Random scissors. Anything but the rotary tool. I have to take it off to cut it. At this point my partner has come to help because I am clearly agitated, lol (and coffee is dripping anyway).

Okay, so despite the fact that this weather stripping is from the same brand as the previous one, the holes don't line up. So I have to make new holes in the door. No problem... I take it off (ow btw, it was on very tight), cut it shorter, put it back on, hammer it for several minutes while making sure it doesnt slip off further in, but because I'm sitting on my ass on a tile floor I can't get enough pressure to actually get the screws to catch. I am too stubborn and angry to put a drill bit on and try to do this right, so I kinda just grab the door handle with one hand and press with the other. It works.

Time to test. The stripping now makes the worst sound imaginable when we open the door. It is the Bad Noise. I am utterly spent today already and now I'm being goddamn triggered by my own front door.

I hate weather stripping.

Edit: OK look I framed houses for like 8 months, it was easier than this as far as finnickiness goes. Maybe next time it's better just to get someone who actually knows what they're doing.

Uncritical support for you in your fight against the draft.

[–] [email protected] 4 points 1 day ago

Thank you! Having it without the stripping is always shocking because I can feel so much cold air coming in, always surprising.

I tried to watch "Interview with the Vampire" and all I could think of was Lestat explaining "The D.E.N.N.I.S." system to Brad Pitt

[–] [email protected] 6 points 1 day ago

Correct reaction tbh.

[–] [email protected] 3 points 1 day ago

All I could think of was that taxi driver in Deadpool 2.

paul schraders cat people is an interesting and horny film. i'm not sure i'd recommend it or quite call it "good," but it was an interesting ride. watched for spooky season but it's not really a horror movie.

The drive my NixOS install was on started failing, so I bought a new one and reinstalled. Literally spent more time trying to get the new drive in than I did getting Nix up and running again. sicko-tux

[–] [email protected] 4 points 1 day ago (1 children)

Sicko tux is very appropriate.

I tried NixOS for a month or two, on my desktop and on a VPS. It was really cool, but there are too many niche things I need to tweak which Nix makes difficult. I do have a self-bootstrapping Emacs init file which works kind of like this though. Just gotta drop one file in place and it installs and configures everything.

[–] [email protected] 2 points 1 day ago

I was already pretty sold on nix due to the config files basically forcing me to self document changes, and the rollbacks saving me when I inevitably screwed something up, but getting a chance to see it actually work and totally recreate my system was very cool. So far anything I want to change has been in the nixos options, or home-manager options, or someone's made a flake for it that I can just pull in so I haven't had to get too deep, which is great for me because I'm a dumbass who barely knows what they're doing

OK so apparently on my phone opening the emote picker just freezes the browser, but like in a softlock sort of state where animations still play, I just can't type or click or anything. Has anyone seen this? I'm using the PWA with Vanadium. I assume itd work in the browser?

Edit: it does not work in the browser either

Edit: leslie-shining it works in Fennec, am I ever glad I can just switch browsers...

It's shocking how often short-form pop science content is just straight up wrong, and not even in the Veritasium way where the videos are misleading in a way that makes them more sensational, just wrong for no reason about high school level physics. Surely it can't lead to that much increased engagement, they must be made specifically to torment me.

If I'm ever a grandparent I'll tell you what, I am going to lie all the fucking time. I am going to give those kids so much misinformation. They will not know what is real and what isnt. I am going to completely rattle their entire worldview, alright? And it's not gonna be just my grandchildren, its gonna be everyone until they're like, "I think gramps has the dementia. I think we should send them to the home." and then I lock it the fuck in because it was a bit. You're not sending me anywhere. I'm locked in. Suddenly I'm perfect again, right as rain. I'm gonna get in people's heads. I think that's some of the most fun you can have as an old person. That and petty crime.
