I'm looking for a way to clear all of my arrays in a Perl program. Currently, I'm calling a subroutine that explicitly "resets" all arrays: sub clear_arrays{(@array1,@array2,@array3)=((),(),());} This forces me to find all the arrays in the program and literally reference them in the subroutine. I've looked at the perldoc for reset , undef , and delete but couldn't interpret any of them in a way that would clear all arrays. Is there a built-in function of Perl that can do this? If not, is there a function that would return an array of all the array variables? Ex: my @prog_arrays = getarrays();

I have a simple form like below that I have added the jQuery validations plugin onto ( http://docs.jquery.com/Plugins/Validation ). I have this form in a modal popup window so if there are errors and the user closes the window when they open it again the form still has the errors. In my popup close callback I tried calling resetForm() but it says the method doesn't exist. Form HTML: <form class="validations" id="commentForm" method="get" action=""> <p> <label for="name">Name</label> <em>*</em><input id="name" name="name" size="25" class="required" minlength="2" /> </p> <p> <label for="email">E

I was looking for posts regarding to this, but I don't fully understand... What is the difference between: [context reset]; and: for (NSManagedObjectID *objId in objectIds) { [context deleteObject:[context objectWithID:objId]]; } Or are they equivalent? Thanks Using reset puts the managed object context back to the state it was in when you first created it-- before you had performed any fetches, created any new objects, etc. If you have any managed objects in memory that were fetched from this context, they're now unusable. Using reset does not affect the persistent store file . All instances

1.概念：uboot主要用来启动内核，启动内核则是用的命令来的；他有众多命令，如信息查询，环境变量操作，内存操作，网络操作，mmc操作，文件系统操作，nand操作，boot操作，reset, go(到指定地址执行程序)，run(运行环境变量中的命令)，metest(内存测试) 2.配置：当输入“make xxx_defconfig”的时候就会匹配到%config 目标，目标“%config”依赖于 scripts_basic、outputmakefile 和 FORCE 3.编译：过程如下 4.启动流程 _start 里是reset 和中断向量表 _start: #ifdef CONFIG_SYS_DV_NOR_BOOT_CFG .word CONFIG_SYS_DV_NOR_BOOT_CFG #endif b reset ldr pc, _undefined_instruction ldr pc, _software_interrupt ldr pc, _prefetch_abort ldr pc, _data_abort ldr pc, _not_used ldr pc, _irq ldr pc, _fiq　 reset 函数跳转到了 save_boot_params 函数， reset: /* Allow the board to save important

1. Git的三种状态 已提交 committed 已暂存 staged 已修改 modified 2. Git的三个区域 Git仓库 是 Git 用来保存项目的元数据和对象数据库的地方。 这是 Git 中最重要的部分，从其它计算机克隆仓库时，拷贝的就是这里的数据。 暂存区域 暂存区域是一个文件，保存了下次将提交的文件列表信息，一般在 Git 仓库目录中。 有时候也被称作`‘索引’'，不过一般说法还是叫暂存区域。 工作目录 工作目录是对项目的某个版本独立提取出来的内容。 这些从 Git 仓库的压缩数据库中提取出来的文件，放在磁盘上供你使用或修改。 3. 基本的 Git 工作流程 在工作目录修改文件 暂存文件，将文件的快照放入暂存区 提交更新，找到暂存去文件，将快照永久性存储到 Git 仓库目录。 3.1 用户信息 [!NOTE] 当安装完 Git 应该做的第一件事就是设置你的用户名称与邮件地址。 这样做很重要，因为每一个 Git 的提交都会使用这些信息，并且它会写入到你的每一次提交中，不可更改。 git config --global user.name "huyaocode" git config --global user.email johndoe@example.com 3.2 加入暂存区 git add 文件名或路径 3.3 忽略文件 创建一个 .gitignore 文件

I have a table to make temporary id`s . When i delete all of the rows of my table , auto increment value for this table will reset to 0 . but i don't want to reset the auto increment. What can i do? Compare TRUNCATE TABLE : Any AUTO_INCREMENT value is reset to its start value. This is true even for MyISAM and InnoDB, which normally do not reuse sequence values. ... with DELETE FROM : If you delete the row containing the maximum value for an AUTO_INCREMENT column, the value is not reused for a MyISAM or InnoDB table. If you delete all rows in the table with DELETE FROM tbl_name (without a WHERE

I'm looking for a way to determine whether an ARM processor is booting from a cold boot (i.e. initial power-on) versus a warm boot (i.e. reset assertion without actual power loss). Specifically I'm using an ARM968 core, will be making the determination using C or assembly, and I will use the determination so certain operations only run on the initial power-on and not on subsequent resets. In previous projects I've leveraged external circuitry (e.g. FPGA) to detect the different boot scenarios, but in this case I am limited to the ARM core. You can initialize a global variable in RAM to a value

My code uses MemoryStream to serialize/deserialize objects to/from the network. I would like to re-use a single MemoryStream in my class, rather than create a new one each time I need to send something over the wire. Does anyone know how to do this? Code snippet: // Serialize object to buffer public byte[] Serialize(object value) { if (value == null) return null; MemoryStream _memoryStream = new MemoryStream(); _memoryStream.Seek(0, 0); _bf.Serialize(_memoryStream, value); return _memoryStream.GetBuffer(); } // Deserialize buffer to object public object Deserialize(byte[] someBytes) { if
