In England the currency is made up of pound, £, and pence, p, and there are eight coins in general circulation:

1p, 2p, 5p, 10p, 20p, 50p, £1 (100p) and £2 (200p).

It is possible to make £2 in the following way:

1×£1 + 1×50p + 2×20p + 1×5p + 1×2p + 3×1p

How many different ways can £2 be made using any number of coins?

Consider all integer combinations of \(a^b\) for \(2 ≤ a ≤ 5\) and \(2 ≤ b ≤ 5\):

If they are then placed in numerical order, with any repeats removed, we get the following sequence of 15 distinct terms:

4, 8, 9, 16, 25, 27, 32, 64, 81, 125, 243, 256, 625, 1024, 3125

How many distinct terms are in the sequence generated by \(a^b\) for \(2 ≤ a ≤ 100\) and \(2 ≤ b ≤ 100\)?

Euler discovered the remarkable quadratic formula:

It turns out that the formula will produce 40 primes for the consecutive integer values \(0 \le n \le 39\). However, when \(n = 40, 40^2 + 40 + 41 = 40(40 + 1) + 41\) is divisible by 41, and certainly when \(n = 41, 41^2 + 41 + 41\) is clearly divisible by 41.

The incredible formula \(n^2 - 79n + 1601\) was discovered, which produces 80 primes for the consecutive values \(0 \le n \le 79\). The product of the coefficients, −79 and 1601, is −126479.

Considering quadratics of the form:

\(n^2 + an + b\), where \(|a|< 1000\) and \(|b|\le1000\)

where \(|n|\) is the modulus/absolute value of \(n\)

e.g. \(|11| = 11\) and \(|−4| = 4\)

Find the product of the coefficients, \(a\) and \(b\), for the quadratic expression that produces the maximum number of primes for consecutive values of \(n\), starting with \(n = 0\).

8月的时候其实sae已经欠费停应用了，已经开始大规模迁移github.io了

但是其实到现在还有那么若干篇关于FR的还没弄过来

还有一些python小应用什么的没有弄过来

至少这种一天48云豆的实在接受不能，算下来还没有在AWS上面搭个instance合算（阿里云不知道，没用过）

后来发现其实我也就是弄弄小前端，根本不需要嘛

实质性的改变就是，我的兴趣直接从python+django转移到了js和相关的各种jquery, typescript, react上了

之前在群里就听到小伙伴说网易要代理Minecraft。

小伙伴是丢了一mc.163.com，评论道，还有若干看上去很逗逼的宣传视频，然后没有了，有了，了。。。

官方声明

搜了一堆资料，不太明白网易以什么形式代理，不过知乎上面已经各种讨论了，如何看待网易代理 Minecraft ？

我得到的信息好像是这样：

1. 好像和java版本没关系……
2. 好像和已经买的正版账号没关系……
3. 会有中国定制版本，按照视频的特点，说不定会有中国功夫（<–这个是我的脑洞）
4. 没玩过网易代理的魔兽，所以不太理解买断的涵义
5. 各种懵逼……

最近迷恋上了Minecraft这款游戏。

其实知乎介绍了很久了，但是一直没尝试。

一开始也就是很无耻地在安卓上玩盗版，但是玩着玩着就是在忍不住买了个PC正版的帐号。

下面的安装都没测试，都是靠记忆，要是出问题我不负责

我只是因为AWS免费套餐到期，把里面的配置文件拉出来备份下

sudo apt-get install nginx
sudo apt-get install python-dev
sudo apt-get install uwsgi
sudo apt-get install uwsgi-plugin-python

uwsgi 测试

uwsgi --http-socket :9090 --plugin python --wsgi-file XXXX.py --process 3

各种配置文件链接

ln -s /home/XX/XX/XX/uwsgi.ini /etc/uwsgi/apps-enabled/

nginx同理

nginx配置

server {
    listen      80;
    server_name xx.xx.xx.xx;
    access_log  /home/ubuntu/nginx_conf/log/access.log;
    error_log   /home/ubuntu/nginx_conf/log/error.log;

    location /static {
        alias /home/xx/xx/xx/project/static;
    }

    location /test { #test去掉就是根目录
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:9090;
        uwsgi_param UWSGI_SCRIPT django_wsgi;
        uwsgi_param SCRIPT_NAME /test;# test..
        uwsgi_modifier1 30;
        proxy_read_timeout 300;
        proxy_connect_timeout 300;
        proxy_redirect off;
    }
}

uwsgi配置

[uwsgi]
chdir           = /home/xx/project
module          = projectname.wsgi:application
master          = true

plugin          = python
process         = 4
chmod-socket    = 666
buffer-size     = 49152
threads         = 2
max-requests    = 6000
vacuum          = true
daemonize       = /home/xx/xx/xx/uwsgi.log
