我是2024-09-03日入住，在2024-10-02日抄得室内水表和房外电表读数。用水约1方（5元），用电约36度（1.5元）。按照租房合同：单间房租850元，卫生管理费30元。合计：850 + 30 + (1+1)x5 + 36x1.5 = 944元。其中，用水低于2方的，按2方计。一开始，我还以为房东每月送2方水用，原来“基数”指的“计费的最小用水量值”。合同部分原文是：“每水水费以2吨为‘基数’，超过基数则按实际用量收取”。我理解有错误。

吃过早餐后，约九点多，躺在床上时，我突然想去看看新闻里提到的天河公园“相亲角”。我先在网上查了一下出行的线路，从附近的“沐陂村口”坐496路公交车到“科韵路站”下车，走一小段路就能到了。

差不多十点时，我上了公交车，当走到天河公园的“小东门”时，约十点半。来的路上，在建业路那，科技园区里有“国家级”的科技公司字样。路的另一边建筑物有中国银行、建设银行和广州酒家等。

进到公园里，游人不少，各个年龄段的都有：青年、中老年；牵着小孩手的、推婴儿车的，也有护着不能自主走路老人的；有男女一起的、有亲戚一大家的、也有一个人跑步健身的。公园里树多、草坪绿，空气挺好的。路边的，一般是多茎多须的榕树；偶尔也可以看到小掇的竹子。我不识得路，也分不清方向，就是随着较多的人流走。走到一个湖，湖的一边有老年人跳广场舞，另一边是很多小孩往湖边扔食物，引得水里那些暗红的身影围绕着游动，时不时会有一条鲤鱼冒出水面，张开大嘴，吞下食物，投喂鱼食的小孩看到后会很高兴。我再往前走，看到一个小卖部，里边写着鱼料3元一包。前边正中是个多层级的平台，每上几个台阶就是一个平台，就像一个多层的蛋糕。每个平台里隔一段会有一桌围聚的人：有打纸牌的、也有下象棋的。越往上走，越接近原生态的山。路是人走出来的小土路，四通八达，想走哪儿就去哪。公园设有几个公厕，挺方便的。

我感觉我已经走了大半圈，从东门到北门，再到了小卖部，没看到新闻里提到“人山人海的相亲角”。我就去问路人。

“请问，‘相亲角’应该怎么走？”
“左边沿路，往上走，就会看到的了。现在没到时间，要12:30左右才会挂（信息）牌，下午两点左右的时候人较多。你再在公园里转一转。”
“‘相亲角’这么有名，为什么没有在公园的地图立牌里标出呢？”
“哪里出名。有的（信息）挂了很久了。你不要加群啊，小心被骗。”路人好心地提醒我。
“是不是这里？我之前经过一个小广场，有两边立着几条像晾衣绳的杆子，里边有不少人踢毽子。”我指着我手机上拍的一张相片问。
"是的，是这里。那些线是用来挂征婚信息纸张的。"

我没等到十二点半“相亲角”开放，因为肚子饿，原路搭496路公交车返回了。

上午约十点，我从出租屋出发，打算走路到新塘菜市场，找“袁小饺”店，因为我在“美团”上买了一份5块钱的15个“玉米鲜肉云吞”。

我沿“沐陂大街”，由西向东，一直走到“沐陂公园”那儿。我停了下来，站在立交桥下，查看手机app上的地图。我在犹豫：前边有条分岔路：一条上坡，沿立交桥下走；另一条是需要穿过桥洞，不知道是能到哪。我问附近一个站着，戴着施工安全帽的人，他回答说往上坡走就行。我走出立交桥后，看到了路边建筑有“天河星作”的字样，知道到“合景路”了。我再往前走一小段，看到了“私立华联学院”的大门。这附近有“沐陂村”的公交站。然后我再走约五百米，左转进入“酉约新村大街”，再拐两个弯，看到了座公祠：“惠言简公祠”。我看了两遍，才记下了名字。

公祠旁边有菜市的入口，我走进，看到门附近有一间铺的招牌是“客家豆腐”，摆着有水豆腐卖。我继续往前走，边走边四周看，找“袁小饺”的招牌。走不一会儿，看到了。这是一间如报亭般的玻璃房，里边有三个工作人员。我在窗口打了招呼，说从“美团”下的单子。工作人员用手机扫码核销后，将饺子装进一条胶袋里递出来，我接住。我继续在市场里逛。菜市场很大，估计有几千平方米，顶栅好像是铁皮的，半开放的。这里有很多档（铺）位。有卖鱼的、卖鸡的、卖青菜的，也有卖干货，卖包装食品的。档位上基本上摆满了货品，逛市场的人不多。我倒回到之前进来时的豆腐铺。买了一块“嫩豆腐”，1.5元钱。那里还有2元/块的“老豆腐”。老板熟练地用一张小铁皮将水豆腐从托板里铲开，放进胶袋里。

我走出市场，找到停在路边的共享单车，准备骑回出租房。上车之前，我特意将装着豆腐和饺子的胶袋各自打上活结，想避免路上颠簸将饺子抛出。骑了约15分钟，回到了。果然，有几个饺子从单车的车筐篮的间隙里漏出，挂着。豆腐的情况不太好，因为颠簸，将成整块的豆腐，给震碎、震裂了。我心疼地提起豆腐的袋子，四周看了个遍，评估约有一半的豆腐还是成型的。我只想到，不让豆腐给颠簸的抛出车筐篮，但没料到豆腐是软的，是经不起震动的。

我煮开了水，放入八个饺子，再将在“美团”上买的秋葵放到锅里。煮几分钟，最后放进水豆腐。即使有些是碎成小块的豆腐，我都放进锅里了，一锅熟。煮好后，我托着锅底，夹豆腐吃，觉得还不错：咬开的豆腐不会有小坑，口感嫩滑，不会布，有豆腐味；汤底也不会煮成豆浆那般。不知道是否因为我过久没吃水豆腐了，这次在广州吃的，觉得比在和平的东水豆腐还要好点。

环境：服务端是 postfix + sqlite3 ，当 roundcube webmail 配置了 password 插件后，用户能更改密码，但之后 postfix 报错，错误信息是 SQL prepare failed: disk I/O error 。影响的结果是，收不了邮件。

原因：roundcube 的 sqlite 连接配置时，使用了 PRAGMA journal_mode = WAL ，但 postfix 不支持。

尝试：可将 sqlite 的 journal_mode 更改回原来的 delete 。如在Linux里执行命令： sqlite3 /var/vmail/postfixadmin.db 'PRAGMA journal_mode=delete;'

# sqlite3 /var/vmail/postfixadmin.db
SQLite version 3.40.1 2022-12-28 14:03:47
Enter ".help" for usage hints.
sqlite> PRAGMA journal_mode;
delete

参考：

• https://github.com/roundcube/roundcubemail/blob/master/program/lib/Roundcube/db/sqlite.php
• https://www.sqlite.org/pragma.html#pragma_journal_mode
• https://github.com/ddavness/power-mailinabox/issues/85
• https://dovecot.org/list/dovecot/2019-February/114794.html

需求：在 debian 12 系统里搭建用 postfix 和 dovecot ，用 sqlite3 存储，postfixadmin 管理，roundcube 作为 webmail 。
