Windows 10 KMS Activation Servers

Basic technique

As it is spread over the Internet, open up a command prompt (Admin) by pressing Win + x, and then enter the following:

slmgr /ipk <you license key>
slmgr /skms kms.xspace.in
slmgr /ato

But then kms.xspace.in is dead.

Here are some alternatives:

kms.shuax.com
kms.landiannews.com
skms 3rss.vicp.net:20439
zh.us.to
skms.ddns.net

And then to clear KMS:

slmgr /skms localhost
slmgr.vbs /ckms

License Keys

To get the license keys, you go ahead Google it..

Turn Stale SmartPhone Into SecCamera?

I was having this idea for a long long time. Yesterday my friends and I were talking about it again. Well, apparently others have done so, if you Google it. Below is a very short list of things I found online (there are tons of apps and companies doing so).

  • https://www.camio.com/
  • http://www.makeuseof.com/tag/use-old-smartphone-tablet-security-camera/
  • https://play.google.com/store/apps/details?id=com.mantishrimp.salienteye

But it occurs to me to understand why this method isn't so popular. Many companies are making expensive security cameras, and people still buy them. Maybe because we trust things that are dedicated to what they are made for? Then I see that Yi (belonged to XiaoMi) released low-cost security camera (around $30), and a lot of people like it, including me. I realized that it isn't we don't trust low-cost solutions to leverage old smartphones for surveillance. We like them and buy them because we simply don't care, because most of us simply like new stuff.

No matter how easy the setup is for the whole "using old smartphone as monitoring system," old stuff is old. We no longer want to touch the old phones. Maybe they are painfully slow. Maybe they have been sitting in the dust for so long. Maybe some functionality in the phone do not work any more. Maybe they carry so many memories and emotionally we do not want to revisit. And we move on, we get new phones, why do we turn back?

Sony DPT-S1 13.3" Testmode

Okay I know this is not new and people have discussed about it, but I still want to post something here to log the process.

To get in the Testmode, just connect to your DPT-S1 and create an empty file named "rVPzp8O1j0m01oOq.crsZVu8crtmXGrc2". Then reboot it, press HOME key once to get back to the home. And then press MENU key four to six times (first time you press it you will see the time on top left corner). Then you will get into the Test Mode app. Online people said you need to press BACK button along with HOME key three times, but mine work with just pressing MENU buttons.

If you see black screen, just press once BACK button and you should be able to see Test Mode.

I think Sony updated the Test Mode in version 1.5.50.11180. My "Update Sony Reader file" shows "NG: file not found" instead of "sr.bin is not found".

Quickly Scan Local Network

Recently I need to quickly scan the local network and find my other device's IP address. I do not have access to the access point, and my device does not report its IP so I cannot directly get what I want. But using another device (laptop specifically), I can quickly find out the IP address of that device.

Just simply do:

for ip in $(seq 1 254); do echo $ip; nmap -sP --max-retries=1 --host-timeout=10ms 10.0.0.$ip | grep "Host is up"; done

Since we are under the same network (assuming my IP is 10.0.0.xx), we will have very low latency (so we can set low timeout). And then this prints:

1
Host is up (xxxs latency).
2
3
...
61
Host is up (xxxs latency).
...
206
Host is up (xxxs latency).
...

That means:

  • 10.0.0.1 is my gateway (access point)
  • 10.0.0.61 is me
  • And of course the one left is 10.0.0.206, which is my device's IP

Sony DPT S1 13.3" E-ink Reader

Eyes feel drained and tired after reading from the laptop.. So glad we have E-ink readers. Sony DPT S1 has been out for years, and it's price finally drops to an acceptable range. Considering I will have 3 more years of papers to read, I bought it. There would be new tablet out namely Good E-Reader, but I decided not to wait. Besides, from online people have shown by modding hardware you can hack the device and run Android 2.2 on it. Plan to take a look at that.
