OTT Box == Over-the-top media services – Wikipedia

Posted by jpluimers on 2019/12/20

Learned a new term while connecting a Chromecast to a Samsung TV: OTT Box. It is a device that can deliver [WayBack] Over-the-top media services – Wikipedia.

Offline XML Pretty Print

Posted by jpluimers on 2019/12/20

I wrote about [WayBackXML Pretty Print in Online XML Pretty Print many years ago.

That’s all fine for small XML file and on-line usage.

A while ago however, I had two cases where off-line XML pretty printing turned out to be much easier than online XML pretty printing:

  1. pretty-print many XML files in one go
  2. compare large (100 megabyte plus) XML files

So I went searching, especially for a solution that would be available for both nx based platforms (Linux/Mac OS X/etc) and Windows which got me a few options in [WayBack] unix – How to pretty print XML from the command line? – Stack Overflow.

I found [WayBack] tidy to be more practical than [WayBack] xmllint as tidy would split more lines which made it easier for  Beyond Compare (that is very much cross platform!) to spot and show the differences.

Not just easier in the sense that the (already excellent) diff engine from Beyond Compare (which really sets it apart from other differencing tools) but very much easier on the eyes as now differences where on lines below each other in stead of 1000s of character positions in one line you had to scroll through.

There is two important things to remember with tidy that both stem from its ancestry (it originates from an HTML):

  • you have to specify -xml
  • you have to specify the characterset (even though XML can specify it and without a definition, XML by default is UTF8, tidy does not know about that)

These were the command-lines I used on Windows to do the pretty printing:

tidy -xml -utf8 >
xmllint --format >

Another trick is to write a small Delphi program centered around the FormatXMLData call which has been present since Delphi 2007 (see [WayBack] devnet.pdf), but documented since Delphi 2009 in [WayBack] XMLDoc.FormatXMLData Function.

Example code: [WayBack] delphi – How to reformat XML programmatically? – Stack Overflow.

An alternative is to use OmniXML: [WayBack] delphi – Nice bit of code to format an xml string – Stack Overflow

Magic SysRq key – Wikipedia

Posted by jpluimers on 2019/12/20

Cool: Magic SysRq key – Wikipedia

The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system’s state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem.[1] Its effect is similar to the computer’s hardware reset button (or power switch) but with many more options and much more control.

Sometimes reading fluffy fluff posts teaches you new things, so be sure to read this one:

[WayBack] I just got trolled by my cat, hard. Last night i left my linux laptop open and running while watching TV in the other room. I came back to find Marley … – Stephen Shirley – Google+

I started looking through the kernel logs from last night, to see if there was any indication of the issue starting. And then i saw it. One innocent line that said:

Dec 18 21:26:52 x240 kernel: [373001.156356] sysrq: SysRq : Emergency Remount R/O

The fluffy dumbass had somehow hit the Sysrq [0] key combo to mount all filesystems read-only. This is an old, low-level when-all-else-fails facility for dealing with an linux unresponsive system, and fluff-for-brains Marley had somehow hit alt+fn+s+u.
