In-reply-to » Does anyone know what the differences between HTTP/1.1 HTTP/2 and HTTP/3 are? 🤔

HTTP/2 differs from 1.x by becoming a binary protocol, it also multiplexes multiple channels over the same connection and has the ability to prefetch related content to the browser to lower the perceived latency.

HTTP/3 moves the binary protocol from HTTP/2 over to QUIC which is based on UDP instead of TCP. This makes it better suited to mobile or unstable networks where handling of transmission errors can be handled at a higher level.

我有一个绝妙的游戏点子,怎样才能把它做出来?——独立游戏可行性概念篇
如何完成一个独游项目的立项,大概可以这样思考:

1 想做什么?怎么整理自己的点子?

2 怎么确定自己的概念设计可行?怎么进一步推导可行性?

3 评估能力和成本,怎么做好项目的规划和商业化预期?

4 怎么让项目能够落地下来?

我会以“ 烟花”作为命题,来讲讲怎么从“烟花”这个概念拓展为能变成能落地的可行性概念。

一、 灵魂疑问:我有一个绝妙的游戏点子?

人总会容易有一种错觉:我有一个绝妙的游戏点子,只要做出来肯定火。

那问题来了:

这真的能行吗?怎么才算绝妙的点子呢?

答案很简单:

别YY,去外部验证

之前有群友问“烟花”怎么做成独立游戏,这次就以烟花当例子来进行推导。

首先,在动脑前,最好是先到互联网验证一下自己“绝妙的游戏点子”是不是已经有人想出来了,甚至做过了?

先花时间搜一下能很有效的避免重复造轮子。

下面是一个随便一点的流程。

奥运乒乓球决赛,为什么莫雷加德的衣服干爽而樊振东却大汗满身?
作为一名纺织品化学工程师,我就从纺织材料这个角度来和大家好好聊聊这个问题。

全篇干货没废话,先说下我个人的3个结论

1)衣服看起来出汗明显≠速干效果差,反而可能更好

2)日标的速干衣标准更适合剧烈运动出汗场景

3)樊振东是真的爱出汗体质

一:速干衣为什么比常规的衣服更加容易干燥?

很多消费者都会吐槽涤纶、尼龙这类化学纤维做的衣服穿起来闷热不透气,但实际上恰恰相反,涤纶、尼龙是运动速干衣的主流材料

在问题开始前,有个核心知识点一定要给大家讲清楚,那就是大众所说的“面料透气”是个非常复杂指标,不是面料孔隙多穿上去透气(直接测试透气性其实是防风指标)。

穿着透气不闷汗的本质, 其实是让面料尽可能的吸收皮肤上的汗水,只要皮肤表面干爽你就会觉得穿着透气我们日常觉得棉T吸汗透气,是因为棉花的公定回潮率有8.5%(100g棉花能吸收空气中8.5g的水蒸气),你可以简单的理解成“饼干受潮变软”的这个过程。

樊振东 0-2 落后选择更换球衣,随后找回状态完成大逆转,更换球衣从战术和心理层面有多大影响?
同为世界排名前十的对手,樊振东和张本智和的差距并不算太大。尤其是在这种巅峰对决中,双方的技战术几乎都是透明的了。即便是樊振东的胜面相对比较大,但是临场发挥的能力决定了这次比赛的胜负。由于王楚钦意外爆冷被淘汰,男单的压力就落在了樊振东的身上。

比赛有悬念,竞争更激烈,观众们才更喜欢看,也更符合比赛的本质。在万千人瞩目的焦点战,樊振东一开始就承受了额外的压力,导致失误不断,两局落后。一方面承受着巨大的压力,另一方面连续两局失利,压力陡增。如果任其继续下去,后果将不堪设想。好在短暂的离场更换球衣,能够暂时的从压力中脱离出来,重新投入战斗。

不要小看这短暂的离开,这几乎是胜利天平的转折点。因为运动员一旦压力过大,就发挥不出平时的水平来的。这也是王楚钦之前失利的重要原因。对于如何缓解压力,最有效的方法莫过于暂时的离开当下的环境。根据心理学的研究,人的压力跟比赛成绩,是呈倒U形曲线的关系。最开始的时候 … ⌘ Read more

In-reply-to » Bought a motorcycle this summer, I did not want two cars, and Marlyn would like to have the car more when I'm at work. So I bought a new cheap motorcycle, KTM Adventure 390. It's been 10 years since I last had a motorcycle (back then I had a KTM 990cc). Here I am with my daughter on the new bike :) My kids love to go for rides, so does Marlyn as well, so it's a lot of fun for all of us. Media

@bender@twtxt.net It cost what you mentioned here too, but they had a special discount, and the shop gave 20% discount for all the gear we needed (since I bought the bike + gear for two persons), so all in all I got a really good deal on it. Also interest rate is locked for 3 years (low rate) so that was also a good deal.
I just took the longest time I could on the loan, to have a low price each month, and then i just pay extra whenever I can to get it payed down faster.
Luckily the Marlyn, my son, and my daughter all fit the same gear, so the 3 of them share that, that saved a lot of money too :)

When i met Marlyn (before we had kids) I asked here to go on her first trip with me (I had a bike before I met her back then), and we went on a 2 week ride from Norway to Italy and back (venice) through the alps and all that. Was super fun, and I think it’s pretty cool of her to say yes to a 2 week trip as passenger :)

【The K 聊汽车安全(2)】汽车工程是如何进行人体伤害评价的?
汽车碰撞安全设计主要考量的,就是在发生碰撞事故时保护乘员和行人等道路弱势群体,减轻事故给乘员和道路弱势群体造成的伤害。

我们在上一讲中已经对全球主要的汽车安全法规和C-NCAP类第三方评价规程进行了详细的解读。

The K:【The K 聊汽车安全(1)】带你认识全球汽车碰撞安全法规

不管是什么安全法规,判断安全性能好坏的标准,都是以人为本,从人可能受到伤害的严重程度出发,综合评价,从而给出车辆的安全等级。

那么,如何对人体所受伤害的严重程度进行评价呢?

总体而言,人体伤害一般分为两个评价维度:第一,人体各部位所能承受的机械载荷限值。第二,根据伤害风险曲线来判断载荷作用下发生伤害的可能性。

一般来说,我们按不同的区域将人体的损伤度量区域分为头部、颈部、胸部、下肢。

如果你不想了解原理,只要在保存气道畅通的情况下了解两点,并且在日常生活中就不断练习到成为习惯:

1.尽量用鼻呼吸,少用或不用口呼吸;

2.学习完全呼吸法,多深呼吸少浅呼吸;

第三次强调, 自行车运动的本质是有氧耐力和无氧耐力,所以我们如何能够获取并利用更多的氧气来和自身产生氧化反应驱动自身,尽量减少进入无氧区间的可能性,同时在必须要进入无氧区间时能维持更久输出更多,就成了整个自行车运动除技巧外的全部,所有的训练也都是围绕着这个目标来制定的。
