There are two glyph variants for the Dollar sign, with one or two vertical bars through the S
LEB128 ("Little-Endian Base 128") is a variable-length encoding for arbitrary signed or unsigned integer quantities. The format was borrowed from the DWARF3 specification. Each byte has its most significant bit set except for the final byte in the sequence, which has its most significant bit clear. The remaining seven bits of each byte are payload, with the least significant seven bits of the quantity in the first byte, the next seven in the second byte and so on.
We must define how many bits there are for LEB128, for example, LEB128-40(5 bytes) can be used to encode 32-bit quantities(have some higer bits not used).
In the case of a signed LEB128 (sleb128), the most significant payload bit of the final byte in the sequence is sign-extended to produce the final value. For example, "80 7f ..." is taken as "80 7f", then sign-extended to "00 ff ff ff", then -128. Another example, "7f ,,," is taken as -1.
In the unsigned case (uleb128), any bits not explicitly represented are interpreted as 0. For example, "80 7f ..." is taken as 80 3f, then 0x3f80
The variant uleb128p1 is used to represent a signed value, where the representation is of the value plus one encoded as a uleb128. This makes the encoding of -1 (alternatively thought of as the unsigned value 0xffffffff) — but no other negative number — a single byte, and is useful in exactly those cases where the represented number must either be non-negative or -1 (or 0xffffffff), and where no other negative values are allowed (or where large unsigned values are unlikely to be needed).
前两天堂哥让我推荐降压保健品，我虽然平时给老爸寄过，但是从来没有系统地了解过这些保健品。对这个我是个大马哈，只能综合一下网络上保健专家和学者的建议，希望对亲友们有用。
降三高要吃药，但是是药三分毒，而保健品呢，不能说没有副作用，但是利大于弊， 它能有效地缓解三高。降三高的药，自然是医生说了算，至于保健品，专家给出的答案是"深海鱼油 + 蜂胶 + 卵磷脂" 的组合。前面两种我是一直给老爸寄的，最后一种是七月份回国前偶然去cosco买的, 今天上网才知道， 这个卵磷脂早就应该给他寄了!！
深海鱼油是深海中的鱼类(三文鱼、沙丁鱼等)体内提炼出的EPA和DHA营养素(我们常说的OMEGA 3就是EPA和DHA；除了这两个，还有一个亚麻酸)，普通河鱼和浅海鱼也有OMEGA 3，但是含量极少。
EPA俗称“血管清道夫”, 能疏通血液中的脂肪块(血脂), 清理血栓，改善血液粘稠度。
DHA是深海鱼油提供的另一个福利，不仅适用于小孩，也适用于老人， 它虽然不是专为三高人群准备的，但也是深海鱼油备受追捧的营养素。 专家称其为“脑黄金”，是脑组织和视神经
卵磷脂俗称“血管垃圾运输车”， 鱼油负责清理和收集血栓和多余的胆固醇血脂等，卵磷脂负责将其排走。
至于蜂胶，专家称因肥胖、环境污染、吸烟喝酒等原因，体内的甘油三脂含量会过高，血小板会过度集中，从而导致高血脂高血压问题，蜂胶能缓解这些问题。
希望这一则小贴士对大家都有帮助, 同时祝亲友们健康快乐，谢谢^^

可以把域和工作组联系起来理解，在工作组上用户登录在本机，密码是放在本机的数据库。而如果你的计算机加入域的话，各种策略是域控制器统一设定，用户名和密码也是放到域控制器去验证，也就是说你的账号密码可以在同一域的任何一台计算机登录。
工作组可以随便出出进进，而域则需要严格控制。 在域模式下，至少有一台服务器负责每一台联入网络的电脑和用户的验证工作，相当于一个单位的门卫一样，称为域控制器DC（通过在一台服务器上安装活动目录（AD），就会将这台计算机安装成dc）。域控制器中包含了由这个域的账户、密码、属于这个域的计算机等信息构成的数据库。当电脑联入网络时，域控制器首先要鉴别这台电脑是否是属于这个域的. 若不能登录，用户就不能访问服务器上有权限保护的资源，他只能以对等网用户的方式访问Windows共享出来的资源，这样就在一定程度上保护了网络上的资源。
要把一台电脑加入域，仅仅使它和服务器在网上邻居中能够相互看到是远远不够的，必须要由网络管理员进行相应的设置，把这台电脑加入到域中。这样才能实现文件的共享，集中统一，便于管理。
工作组是一群计算机的集合，它仅仅是一个逻辑的集合，各自计算机还是各自管理的，你要访问其中的计算机，还是要到被访问计算机上来实现用户验证的。而域不同，域是一个有安全边界的计算机集合，在同一个域中的计算机彼此之间已经建立了信任关系，在域内访问其他机器，不再需要被访问机器的许可了!
域和工作组适用的环境不同，域一般是用在比较大的网络里，工作组则较小，在一个域中需要一台类似服务器的计算机，叫域控服务器，其他电脑如果想互相访问首先都是经过它的，但是工作组则不同，在一个工作组里的所有计算机都是对等的，也就是没有服务器和客户机之分的，但是和域一样，如果一台计算机想访问其他计算机的话首先也要找到这个组中的一台类似组控服务器，组控服务器不是固定的，以选举的方式实现，它存储着这个组的相关信息，找到这台计算机后得到组的信息然后访问。
windows 导航到 Control Panel\System and Security\System, 然后`重命名计算机 并|或 选择域`:
计算机名可以取为例如 分公司-员工号-员工设备ID, Van-40xxxx-FT04, Van-40xxxx-MyNewWorkHost. 域的名字是域管理员给的，照填就行了,比如fortinXX.yy.zz. 域用户名和密码也是。
利用ForensiT公司的迁移工具Profwiz将本地用户迁移到这个域用户:
选择要迁移的本地用户:
选择域用户:
Profwiz实施迁移，迁移完成重启，计算机就可以用域用户登陆了^^,原来的用户就不见了，如果要让它再出来，可以断开域连接，这个不在本文范围内。
have you ever wanna copy one or more snapshots of vbox into a new vm machine? following is an example of how-to.
considering following cases:
in my example, I selected a snapshot named "UpdatedV8":
in my example, I specified "Ubuntu14_64Bit":
in our example, we want the clone to be portable, so select full clone:
in my example, I don't need the tree view, that is, I don't need all previous nodes/states/snapshots, so select "Current machine state":
at last, we have a new vm machine, in my example, it have no previous snapshots, only a "Current State" like following:
on copied, edit shared folder settings to make the new machine can find the shared folder; after that, power on the new machine and it will be okay on host2.
