 {0,2} to be a valid pattern (unlike in Python, where the docs state explicitly that omitting n specifies a lower bound of zero).
But then using {,2} should throw an error instead of returning misleading matches! Am I missing something or should this be reported as a bug?

A:

The behavior with {,2} is not expected, it is a bug. If you have a look at the TRE source code, tre_parse_bound method, you will see that the min variable value is set to -1 before the engine tries to initialize the minimum bound. It seems that the number of "repeats" in case the minimum value is missing in the quantifier is the number of maximum value + 1 (as if the repeat number equals max - min = max - (-1) = max+1).
So, a{,} matches one occurrence of a. Same as a{, } or a{,     }. See R demo, only abc is matched with ab{,}c:
grepl("ab{,}c", c("ac", "abc", "abbc", "abbbc", "abbbbc"))
grepl("ab{, }c", c("ac", "abc", "abbc", "abbbc", "abbbbc"))
grepl("ab{,   }c", c("ac", "abc", "abbc", "abbbc", "abbbbc"))

 Q:

Can I use Titan XP on MacBook?

Is the Nvidia's Titan XP compatible with Apple's MacBook (mid-2017)? I have never used external GPU but it seems to be that you can use it on MacBook Pro.
However, MacBook doesn't have Thunderbolt.
Is it possible to use Titan XP on MacBook, with a connector like Thunderbolt to USB 3.1? Is the performance drained via the connector and not a good solution in general?
The use cases are deep neural net and I don't use gaming, for your information.

A:

No you really need a Thunderbolt connection.
It wasn't until Thunderbolt 3 that the bandwidth of the protocol fully caught up with the idea. Realizing this, the group responsible for the spec created implementations with the possibility of some configurations being able to pass the video signal back to the computer it
{ 0,2 } to be a valid pattern (unlike in Python, where the docs state explicitly that omitting n specifies a lower bounce of zero). 
 But then use {, 2 } should throw an error instead of render misleading matches! Am I miss something or should this be reported as a bug? 

 angstrom: 

 The behavior with {, 2 } is not expected, it is a microbe. If you have a look at the TRE generator code, tre_parse_bound method, you will see that the min variable value is set to -1 before the engine tries to format the minimum bound. It seems that the number of " repeat " in case the minimum value is missing in the quantifier is the number of maximum value + 1 (as if the repeat act equals max - min = max - (-1) = max+1).
