Vysor is back, new features, paid option – via koush’ stream at G+

Posted by jpluimers on 2016/05/26

Vysor now (again, bug fixed) shows undistorted on my Mac

Vysor now (again, bug fixed) shows undistorted on my Mac

Be sure to read the comments at Vysor is back, new features, paid option… there are a few gems in there including an upcoming Server based Vysor (yes, managing Android Farms!).

  • Pro subscription is just USD 10 (or EUR 7.50) a year.
    • Or USD 2 (EUR 1.50) a month.
  • There is a a troubleshooting page.

The screen resolution still isn’t what it used to be, but I hope that bug gets fixed soon as well.

Anyway: “A window to your Android: Vysor – Chrome Web Store

A lot of people use Vysor, mostly developers. There are nearly 20,000 active users per day. Half of those users are using it for over 4 hours a day.

I spent the weekend trying to figure out how to get the app back online for everyone, and in a sustainable freemium model. To that end:

  • I removed the infringing h264 decoder and switched to the Chrome’s internal (ie, not packaged with Vysor) Pepper VideoDecoder introduced in Chrome 48.
  • Vysor is now a subscription app.

…  this weekend, I put my big boy pants on and implemented billing and some new features to go with it.

Here’s what Pro users get:

  • High quality mirroring (free is 500Kbps, Pro gets you up to 2Mbit). This was made possible due to the new decoder.
  • Fullscreen mode.
  • Drag and drop files and APKs.
  • Vysor Share.
  • Some other features I have in the pipeline but did not make this release.

Vysor’s free version isn’t ad supported, I think that would ruin this sort of app. Your support as paid users is appreciated.

History: Vysor is no longer available – h264 licensingI voluntarily unpublished the Chrome app just now. Some MPEG-LA folks got in touch with me about licensing… – Koushik Dutta (Koush) – Google+

As Vysor sort of is open source, you can view github history.

domain name system – How to test DNS glue record? – Server Fault

Posted by jpluimers on 2016/05/26

Thanks Adrian W for providing the below example in your answer about obtaining GLUE record information for a domain.

It is an excellent showcase for the $IFS Internal Field Separator available in any nx shell.

In this case it is used to get the TLD (top-level domain) from the domain name specified at the command-line.

After that, it obtains the name servers for that TLD, and queries the glue records there, both using dig.

Here is a little shell script which implements Alnitak’s answer:

for P in $1; do

echo "TLD: ${TLD}"
DNSLIST=$(dig +short ${TLD}. NS)
for DNS in ${DNSLIST}; do
  echo "Checking ${DNS}"
  dig +norec +nocomments +noquestion +nostats +nocmd @${DNS} $1 NS

Pass the name of the domain as parameter:
