For example: START n=node(144) RETURN n; How would I get the last node that was created? I know I could show all nodes and then run the same command in anotehr query with the corresponding ID, but is there a way to do this quickly? Can I order nodes by id and limit by 1? Is there a simpler way? Either way I have not figured out how to do so through a simple cypher query. 回答1: Every time not guaranteed

Here's my code: $new_user = get_userdata($user_id); //$user_id is passed as a parameter $first_name1 = $new_user->user_firstname; $last_name1 = $new_user->user_lastname; echo "<" . $first_name1 . $last_name1 . ">"; //returns: <> $first_name2 = $new_user-first_name; $last_name2 = $new_user->last_name; echo "<" . $first_name2 . $last_name2 . ">"; //returns: <> According to the codex , this should work, but when I echo $first_name or $last_name they're empty. Strangely, THIS does work: $id = $new_user->ID; Am I doing

I am trying to set a range so that it will go from A1 to the end of the data in the A column. This spreadsheet will be updated weekly so there will be data added to it every week. I was wondering what code would work so that I can either find the row number and somehow tie it in with my range code so that it will equal "A" + lastrownumber ? OR if there is code that will provide the column and row number together? If I have missed the

At the moment, I have to set a do-once variable and catch the Invalidated event. 回答1: Have a look at this link here that explains about the order of winforms events firing. 回答2: What about VisibleChanged ? 文章来源: What's the last possible event I can catch after a user control has been shown in .net, winforms?

See example: http://fiddle.jshell.net/X3jPh/770/ 回答1: In addition to the showLastLabel property, you may need to add the endOnTick flag to your example. For example: //... xAxis: [{ type: 'datetime', showLastLabel: true, endOnTick: true }, //... 回答2: Use tickPositions Array:(number) to specifically identify which indices you want displayed on your xAxis. 文章来源: HighCharts - show last labels in xAxis

EDIT: Crittercism has a crittercismDidCrashOnLastLoad method, but it only handles the case of crashing during load. It didn't work properly in the version of the library I used, but this has since been fixed. Suggestions? 回答1: Make 2 functions in your AppDelegate.m file: void HandleException(NSException *exception) { NSLog(@"App crashing with exception: %@", exception); //Save somewhere that your app has

为了方便对redis进行监控管理，一些公司会自己开发监控，或在已有的系统中添加功能。对redis info信息的获取是必须要处理的。Redis Info信息包括Server,Clients,Memory,Persistence,Stats,Replication,CPU,Commandstats,Cluster,Keyspace等，下边我们详细介绍各部分对应信息。 Server： redis_version Redis 服务器版本 redis_git_sha1 Git SHA1 redis_git_dirty Git dirty flag redis_build_id Git dirty flag redis_mode 运行模式，单机或者集群 os 服务器的宿主操作系统 arch_bits 架构（32 或 64 位） multiplexing_api Redis 所使用的事件处理机制 atomicvar_api 原子处理api gcc_version 编译 Redis 时所使用的 GCC 版本 process_id 服务器进程的 PID run_id Redis 服务器的随机标识符（用于 Sentinel 和集群） tcp_port uptime_in_seconds 自 Redis 服务器启动以来，经过的秒数 uptime_in_days 自 Redis 服务器启动以来

Redis的数据回写机制 Redis的数据回写机制分同步和异步两种， 同步回写即SAVE命令，主进程直接向磁盘回写数据。在数据大的情况下会导致系统假死很长时间，所以一般不是推荐的。 异步回写即BGSAVE命令，主进程fork后，复制自身并通过这个新的进程回写磁盘，回写结束后新进程自行关闭。由于这样做不需要主进程阻塞，系统不会假死，一般默认会采用这个方法。 个人感觉方法２采用fork主进程的方式很拙劣，但似乎是唯一的方法。内存中的热数据随时可能修改，要在磁盘上保存某个时间的内存镜像必须要冻结。冻结就会导致假死。fork一个新的进程之后等于复制了当时的一个内存镜像，这样主进程上就不需要冻结，只要子进程上操作就可以了。 在小内存的进程上做一个fork,不需要太多资源，但当这个进程的内存空间以Ｇ为单位时，fork就成为一件很恐怖的操作。何况在16G内存的主机上fork 14G内存的进程呢？肯定会报内存无法分配的。更可气的是，越是改动频繁的主机上fork也越频繁，fork操作本身的代价恐怕也不会比假死好多少。 找到原因之后，直接修改/etc/sysctl.conf内核参数vm.overcommit_memory= 1 sysctl -p Linux内核会根据参数vm.overcommit_memory参数的设置决定是否放行。 vm.overcommit_memory = 0：则比较

(1)添加站点 (2)配置apache配置文件 在/usr/local/apache/conf/vhost文件夹下，修改webApp站点配置文件app.zouke.com.conf,并配置域名app.zouke.com (3)配置nginx配置文件 location / { #ThinkPHP REWRITE支持 if (!- e $request_filename) { rewrite ^/index.php(.*)$ /index.php?s=$ 1 last; rewrite ^(.*)$ /index.php?s=$ 1 last; #rewrite ^(.*)$ /index.php$ 1 break ; break ; } } (5)重启服务:lnmp restart (6)访问webApp站点 原文：https://www.cnblogs.com/zouke1220/p/9323176.html
