VSphere Cilent是一款虚拟平台工具,大多Win10系统在运行VSphere Cilent时都会被提示错误,无法正常运行,这是怎么回事?让小编来给大家分析分析。
原因分析:

Win10系统下无法运行VSphere Cilent,主要是由于Win10的.NET版本是3.5,而VSphere Cilent支持.NET2.0的。

解决方法:

  1. 从一台不是win10的安装了 Microsoft .NET 3.5 SP1的机器里,在这个路径:%SystemRoot%/Microsoft.NET/Framework/v2.0.5010210/,复制system.dll。
  2. 在安装路径里:C:/Program Files/VMware/Infrastructure/Virtual Infrastructure Client/Launcher/

如果是X64系统就是:C:/Program Files (x86)/VMware/Infrastructure/Virtual Infrastructure Client/Launcher/,建立一个文件夹:”Lib”, 将刚才的文件system.dll放在这里。

  1. 编辑C:/Program Files/VMware/Infrastructure/Virtual Infrastructure Client/Launcher/VpxClient.exe.config文件

加入:

  1. 在系统环境变量中建立一个新的环境变量:”DEVPATH”, 值为:C:/Program Files/VMware/Infrastructure/Virtual Infrastructure Client/Launcher/Lib

上述步骤设置完成之后,用户在Win10系统下重新打开VSphere Cilent就能正常运行了。

Ham Pager Setup Base on MMDVM

火腿的第一台传呼机

Ham Pager源于http://hampager.de

寻呼机是多年前,在手机尚未普及时的一种通讯工具,在还有寻呼台的时候,首先我们需要在寻呼台注册。然后缴纳一定的台费和机子费,然后按缴费所购买的时长来提供服务。自从寻呼台相继关闭,曾经寻呼的频率已经清频退网,国内这种服务已经基本不再提供。当然,一些业余兴趣爱好者可以用一定的技术手段来制造一个发射终端,该终端必须在1W以下的功率,因为这个功率范围是免照范围,普通老百姓都可以随意使用。寻呼机最早是摩托罗拉为主导品牌,发展到后期,一些国产的寻呼机在功能和使用性能上已经超越了某些国外品牌。常见的寻呼机编码有两种格式。一种是POCSAG(低速编码),另一种是FLEX高速编码。当然在后期在国内也发明了一些有自主知识产权的编码形式。要想给寻呼机发信息你必须得知道两个基础的信息。第一是寻呼机接收使用的频率。第二是寻呼机的地址码。寻呼机的频率可以通过一些公式计算出来。地址码则需要一定的软件和硬件来读取出来,也可以采用追码的形式追出来(穷举法),寻呼机的地址码最大一般为2097151。

MMDVM, MMDVM_HS_HAT, MMDVM_DUAL_HAT with Pi-Star (Pi*)

What do I need?

Hardware

  • MMDVM
  • MMDVM_HS_Hat
  • MMDVM_DUAL_HAT

with Firmware >= 1.4.1

Software

PiStar >= 3.4.16 or MMDVM-Host Version ???

Which Pagers can be used

How to set up Pi* for PROCSAC (DAPNET) with MMDVM_HS_HAT or MMDVM_DUAL_HAT

Already have a working installation of Pi-Star (Pi*)?

Yes, I have already a running Pi-Star:

Update and Upgrade Pi*’s base system services and packages

  • Login to your Pi* Installation via SSH using Terminal,cmd-Promt or putty (Standard is „ssh pi-star@pi-star“ (you can miss the :22 at the end, because it is the standard port)
ssh pi-star@pi-star [Enter]

Now you will be asked for the Password – Standard-Password is „raspberry“ without „“ or take the password you have changed in Pi-Star Dashboard.

You will see the Welcome Message in ASCII-Signs

Now you have to Enter the following commands:

1. PI* uses a write protection so the command to unlock the filesystem for editing is:

rpi-rw [Enter]

2. Now get the latest Version of Pi* and all needed software components:

sudo pistar-update [Enter]

3. Upgrade the Pi* Installation to the next following Version:

sudo pistar-upgrade [Enter]

Repeat the last command (sudo pistar-upgrade) till you get a message „you have installed the latest Version of Pi* – No update needed“ or a similar message.

It is not possible to directly Upgrade to the newest Version! So you have to repeat the pistar-upgrade several times.

For example: You have installed Pi* Version 3.4.13 and want to get onto Version 3.4.16

You have to use the command „sudo pistar-upgrade“ 3 times to get from 3.4.13 to 3.4.14, than from 3.4.14 to 3.4.15 and 3rd time to get from 3.4.15 to 3.4.16.

The last output in terminal should be:

    You are already running the latest version…
    Sleeping a few seconds before making the disk Read-Only…
    Finished

Upgrade the firmware of your MMDVM-Hardware

for Upgrading MMDVM_HS_Hat board conected to GPIO you have to enter the command:

sudo pistar-mmdvmhshatflash hs_hat [Enter]

for upgrading the original MMDVM-HS_DUAL_HAT board (made by Andy, Florian (DF2ET) and DB9HAT) conected to GPIO you have to enter the command:

sudo pistar-mmdvmhshatflash hs_dual_hat

If you get a message that the flashing process was successfull, the hardest part is done. If not, repeat flashing or ask for help in the „MMDVM-BM“ or „DAPNET User“ Telegram-Messenger Groups.

Do a restart now with

sudo reboot now [Enter]

Configure Pi-Star and enable DAPNET

If not already done you should register on https://www.hampager.de and than Register a New Transmitter.

You will get a „DAPNET AuthKey“ by email if your ticket is arranged by a Team-Member.

Now it`s time to Login into the Pi*-Dashboard!

On a Windows, Mac, or Linux-based computer (not the hotspot itself) that has WiFi enabled, open a browser window and navigate to (trailing slash needed):

  Windows: http://pi-star/
  macOS, iOS, etc.: http://pi-star.local/
  On some mobile devices, the url won't work. In that case, try the Auto AP IP address: 192.168.50.1

Go to Admin Area and hit „Apply Changes“ somewhere, like if you would save any changes – even if you did not change anything. This will reload the page and force Pi* to reload store and reload the Configuration. During this process all missing or by update added sections will be loaded and shown correctly.

Now you should still see the Configuration view and in the „MMDVMHost Configuration“ section, switch on „PROCSAC“ and then click „apply changes“.

The Page will reload – now search for the „POCSAG Configuration“ section and fill out the needed values:

  • Node Callsign POCSAG – Enter the POCSAG node callsign.
  • Radio Frequency POCSAG – Enter the POCSAG radio frequency. Per Andy Taylor in the Pi-Star User Forum : „If we get good buy in from repeater keepers, we could have a really good paging network with great coverage, especially if we all use the same standard frequency.“ In Germany, where are already a lot of repeaters we use 439.987.500MHz, which will be the deafault entry in Pi*!
  • DAPNET AuthKey – Enter your authorization key for the Decentralized Amateur Paging Network. Which you got by Mail after you registered a New Transmitter as I told you on the Beginning of Configure Pi-Star and enable DAPNET

No Pi-Star installed yet:

Please google for a Pi-Star installation guide. A nice one is written by KE0FHS on https://www.toshen.com/ke0fhs/pi-star.htm or visit the main website of the PI-Star-Project under https://www.pistar.uk/

Apple HomePod first look & problem

03/07/2018 | GUIDE | 没有评论

As a chinese user, I ordered an Apple HomePod via Apple officially website. After three weeks, I got my HomePod. There are some problems for using of HomePod in China.

I try servery times on this thing with my Chinese (region) account. It couldn’t work. Always noticed me the error 301009. Right after, I connected with my American (region) account. The Error 301014. I check my itunes ID and change the pay method to Paypal. It works immediately.

I have all my apply music and iCloud subscription on my Chinese account. My solution is to switch to Chinese Account after using the US account finishing the initialization.

Another solution for Error 301014. DO NOT select “Enable Personal Requests” (this is off by default so do not toggle it on)

How to shut down Cortana in Windows 10

01/31/2018 | GUIDE | 没有评论

To shut down Cortana in Windows 10 Pro simply type gpedit.msc in the search box to open the Group Policy Editor. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Search. Double-click the policy named Allow Cortana.

You can kill Cortana easily in Windows 10 Pro via the Group Policy Editor.

When the policy window appears just click Disable. You’re done!


Here’s where you disable her; feels a bit like killing the Terminator.
If you’re using Windows 10 Home, you’ll need to edit the registry. Do not tackle this step unless you have experience editing the registry. Additionally, you should set a restore point now in case things go sideways. To do that just follow these tips.

It bears repeating: This is dangerous. That said, here’s what you do. Type Regedit into the search box in Windows, and open the Registry Editor. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search.

Here’s where it gets tricky: That final key (Windows Search) might not be present, as it wasn’t on my machine. In that case you’ll need to right-click the Windows directory and select New > Key. Name it Windows Search.

The key Windows Search wasn’t present on our machine, so we had to create it (we did this after for this screenshot).
Now select that new key. In the righthand pane, right-click and select new DWORD and name it AllowCortana. Then right-click that value and make sure it’s set to 0.

allowcortana
Once you’ve created this DWORD value just set it to “0,” which translates to “off.”
Sign out, sign back in and you should notice that Cortana has been replaced with a generic search box—woohoo!

One final note: After all this is done, it’s possible that you’ll look in the Task Manager and find Cortana still sitting there, mocking you. Travis told me he was able to kill the process. When I tried it myself it was not only difficult, but once I did I wasn’t able to search at all on my PC, for anything. Clearly Cortana is a tough cookie. She only consumes 39MB, so consider whether she’s more trouble to kill than she’s worth.
