There’s a simple reason all the current hashes end in a or q: the hash is 256 bits, the base32 encoding chops that into groups of 5 bits, and 256 isn’t divisible by 5. The last character of the base32 encoding just has that left-over single bit (256 mod 5 = 1).
So I agree with #3 below, but do you have a source for #1, #2 or #4? I would expect any lack of variability in any part of a hash function’s output would make it more vulnerable to attacks, so designers of hash functions would want to make the whole output vary as much as possible.
Other than the divisible-by-5 thing, my current intuition is it doesn’t matter what part you take.
Hash Structure: Hashes are typically designed so that their outputs have specific statistical properties. The first few characters often have more entropy or variability, meaning they are less likely to have patterns. The last characters may not maintain this randomness, especially if the encoding method has a tendency to produce less varied endings.
Collision Resistance: When using hashes, the goal is to minimize the risk of collisions (different inputs producing the same output). By using the first few characters, you leverage the full distribution of the hash. The last characters may not distribute in the same way, potentially increasing the likelihood of collisions.
Encoding Characteristics: Base32 encoding has a specific structure and padding that might influence the last characters more than the first. If the data being hashed is similar, the last characters may be more similar across different hashes.
Use Cases: In many applications (like generating unique identifiers), the beginning of the hash is often the most informative and varied. Relying on the end might reduce the uniqueness of generated identifiers, especially if a prefix has a specific context or meaning.

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。

It seems like I finally fixed a memory leak in GoBlog yesterday, that sometimes made my blog crashing. How? I used Anthropic’s new Claude 3.5 Sonnet to write me a new HTTP compression middleware that compresses HTTP responses using zstd or gzip when possible. I needed to instruct a few changes and modify some code lines as the initial implementation was wrong, but thereafter, it finally seems to work better than my original implementation that probably leaked some objects anywhere. Claude also helped me to write uni … ⌘ Read more
需要加 5.67 升机油的车，机油加到 5 升的时候启动了，会不会造成磨损拉缸？
我们正常换机油采用的都是重力放油法，机油这种东西本身是粘稠的，按照 重力放是没法完全放干净的。
别说重力放了，机油这种东西，你想特意把它清洗干净，都需要挺大的难度， 所以在每次更换机油的过程中，发动机润滑系统内部以及各个工作面都会残留部分机油。
按照我们目前的工作经验，这个残余的机油量大概会有300到500毫升。
极限状态下，即使你把机油放空，各个工作面其实也是有机油的，短时间原地着一下车，不会对发动机产生任何影响。
如果你的设计机油量是5.5升，那么大部分情况下，实际上加5升就已经达到了原厂设计的机油量，因为发动机内部还会有大概0.5升左右的残留。
而且有的车吧，尤其是豪华品牌，用的是 电子机油尺，不着车你根本就看不到机油量，很大一部分，甚至需要着车怠速半小时以上，才能读取到当前机油量。
