gRPC – Failed at the grpc@1.18.0 install script ‘node-pre-gyp install –fallback-to-build –library=static_library’.

按照官方文档部署环境(也看过别的步骤，但最终还是认为这个最靠谱)，到”Run a gRPC application”->”Run the server”的时候卡住了，npm install 时会报错。

Laravel – 被关联模型的筛选

Laravel 中遇到这种场景： user 表与 meta 表是一对多的关系，结构如下：

user 表
#	名字	类型	排序规则	属性	空	默认	注释	额外
1	id主键	int(10)		UNSIGNED	否	无		AUTO_INCREMENT
2	name	varchar(255)	utf8mb4_unicode_ci		否	无

user 表

# 名字类型排序规则属性空默认注释额外

1 id主键 int(10) UNSIGNED 否无 AUTO_INCREMENT

2 name varchar(255) utf8mb4_unicode_ci 否无

meta 表
#	名字	类型	排序规则	属性	空	默认	注释	额外
1	id主键	int(10)		UNSIGNED	否	无		AUTO_INCREMENT
2	user_id索引	int(10)		UNSIGNED	否	无			
3	meta_key索引	varchar(255)	utf8mb4_unicode_ci		否	无		
4	meta_value	varchar(255)	utf8mb4_unicode_ci		否	无

meta 表

# 名字类型排序规则属性空默认注释额外

1 id主键 int(10) UNSIGNED 否无 AUTO_INCREMENT

2 user_id索引 int(10) UNSIGNED 否无

3 meta_key索引 varchar(255) utf8mb4_unicode_ci 否无

4 meta_value varchar(255) utf8mb4_unicode_ci 否无

user.id 与 meta.user_id 关联。

Laravel – 从 laravel 的报错说起：open_basedir restriction in effect

先说结果：修改了fastcgi.conf中的配置解决问题。

服务器环境用lnmp自动安装的，头一次访问laravel的时候，报500错误，打开日志看了看，报错如下：

拍片儿 – 北京密云不老屯、北京天文台密云观测站，星空，星轨

一直对这种星轨的照片很向往（图自：叠加法星轨的拍摄及后期方法），后来了解到北京密云有个不老屯，也算个北京比较著名（当然也可能算过时）的拍星空的地方，主要的特色是有北京天文台密云观测站、中国科学院国家天文台密云射电天文观测基地（二者指的是同一个地方，后文简称天文台）里的50米射电望远镜以及射电[……]

悬而未决 – perl 程序读取数据库乱码

某系统，正常运行在服务器A，现想搬到服务器B。所有已知的环境至少大版本号都一致，大部分环境版本完全一致。

问题出现：在B上查询本地数据库一个内容是中文的varchar字段，dbi报错，如下：

[user@localhost]$ perl test.pl
SELECT id from TABLE where name= "测试内容" limit 10
DBD::mysql::st execute failed: Illegal mix of collations (gbk_chinese_ci,IMPLICIT) and (latin1_swedish_ci,COERCIBLE) for operation '=' at test.pl line 16.
DBD::mysql::st fetchrow_array failed: fetch() without execute() at test.pl line 17.

[user@localhost]$ perl test.pl

SELECT id from TABLE where name= "测试内容" limit 10

DBD::mysql::st execute failed: Illegal mix of collations (gbk_chinese_ci,IMPLICIT) and (latin1_swedish_ci,COERCIBLE) for operation '=' at test.pl line 16.

DBD::mysql::st fetchrow_array failed: fetch() without execute() at test.pl line 17.

随后就围绕着这个报错开始尝试。[……]

杂 – 亚市二手车过户记录

由于受北京市汽车限购政策的限制，本人平时驾驶的小型客车一直在朋友名下。最近条件允许，便将车过户到我自己名下。一般人也不会经常办过户，有些细节容易忘记。故在此记录一下近日在北京亚市二手车交易市场过户（别人过户到我名下）汽车的过程。由于办事过程仓促，记录的并不是很详细，权当参考。
