Merging multiple commands and piping it to one output.

Posted by jpluimers on 2016/10/20

The unix shell is hard, but boy, sometimes it can work like magic, for instance piping two testssl.sh commands into one gist:

retinambpro1tb:testssl.sh jeroenp$ ( ./testssl.sh --version ; ./testssl.sh --local ) | gist -d "testsll version and local ciphers for Mac OS X Darwin binarries supporting zlib"
https://gist.github.com/701496d7fbf929967aa1

The source of this magic was this AskUbuntu answer: How to merge and pipe results from two different commands to single command? – Ask Ubuntu

via: openssl.Darwin.x86_64 lacks zlib support · Issue #164 · drwetter/testssl.sh

Viewing an USB camera on Mac OS X without mirroring

Posted by jpluimers on 2016/10/03

Even though Photo Booth has an “Auto Flip New Items” option, but that only works for stills, not videos.

I needed it to see without mirroring the images from a DBPOWER 2 Million Pixels Cmos 7M/23FT USB Waterproof HD 6-led Borescope Endoscope Inspection Tube Visual Camera.

What does work are these:

I forget how I bumped into QCamera, but later I found out he posted on apple.stackexchange.com.

Getting the internal TeeChart version numbers

Posted by jpluimers on 2016/08/30

Even though TeeChart uses a year and minor version number during installation, that’s not the only version number available or used.

For instance their bug reporting site bugs.teechart.net uses build versions.

They are easy to get for your product: just look at the units TeeConst, VCLTee.TeeConst or FMXTee.Constants having consts like these:

TeeChartVersion =String('9'); // Cast to String to force CPP *.hpp generation as AnsiString instead of AnsiChar
TeeProductName =String('2015');
TeeVCLMinorVersion ='.15'; // ie: '.01' '.02' , etc
TeeVCLBuildVersion ='150420'; //YYMMDD
TeeVCLBuildVersionInteger = 150420; // <-- Same as above as integer number

You probably get the drift:

  • TeeProductName.TeeVCLMinorVersion is what you see when installed.
  • TeeVCLBuildVersion is what is on the bug report site.
  • TeeChartVersion is in the package names.

It’s sort of documented as well: Steema Central • View topic – How to find TeeChart version number at runtime?

Chrome “Developer Tools” to the rescue. Literally: to salvage a pending forum post.

Posted by jpluimers on 2016/06/02

Lessons learned

  1. Don’t trust online text entry.
  2. Always compose answers in an external text editor, preferably one that understands the markup used (Atom often is a good choice).
  3. Post when ready.
  4. Wonder why every forum software seems to have invented their own markup.

The story

A few weeks ago, while composing an extensive answer on the Scooter Software: Home of Beyond Compare (a tool which – like any development tool – I really love, but sometimes hate): Keyboard handling driving me nuts: how to make it work like BC for Windows, I pressed the “Image” button which:

  1. Made all the edited text to dim and non-selectable
  2. Failed an image selection to show

It was more than an hour of work, so I was determined to try obtaining at least the post text.

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.

Vysor: https://chrome.google.com/webstore/detail/vysor/gidgenkbbabolejbgbpnhbimgjbffefm

Start-up screen with new upgrade option to go pro and new image quality selection.

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.
