问题 I am using Mac OSX 10.10.5, and Python version 3.5.2, and IDLE version 3.5.2. I am extremely new to Python, and am trying to use the urllib3 module in IDLE. I have used the following code in the Terminal with success (the number 200 is returned): import urllib3 http = urllib3.PoolManager() r = http.request('GET', 'http://httpbin.org/robots.txt') r.status But the same code does not work in IDLE. In IDLE I get the following error: Traceback (most recent call last): File "/Users/faculty

Batch blur images using multiple cores

我怕爱的太早我们不能终老 提交于 2019-12-12 04:26:08
问题 I'm trying to blur the bottom section of thousands (>50,000) of images using imagemagick. Image resolution is 800x600. The command line code (below) works, but takes a long time. Is there any way that this can be run in parallel, and hopefully called from within R using system()? I got this code off the internet, so I'm not sure if it's the best way to even achieve this objective? Any help would be greatly appreciated. Thanks in advance!

Does stdin ever contain a carriage return (\r) char?

主宰稳场 提交于 2019-12-12 04:26:03
问题 In an SO answer I wrote this code: char fail_on_eof (int c) { if (c == EOF) exit (EXIT_FAILURE); return (char) c; } void skip_to_next_line (void) { char c; do { c = fail_on_eof (getchar ()); } while (c != '\n'); } I was wondering whether there are any terminals that may return '\r' (which is covered by the above code as long as there is also a '\n' at end of line). Does stdin ever contain '\r' (on any platform)? What about input redirection is stdin always working in text mode? 回答1: Sure, it

Porting an old DOS TUI to ncurses

岁酱吖の 提交于 2019-12-12 04:18:11
问题 I would like to have some advice about how to port an old C++ program written for MS-DOS in the early 90s. This program implements a quite complex text-user interface. The interface code is well separated from the logic, and I don't think it would be too difficult to make it use ncurses. Being a complete novice, I have a few questions: The DOS program intercepts interrupt 0x33 to handle mouse events. The interrupt handler store events in a FIFO, which the main program pools periodically.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . What is the best way to remove all subfolders except ones with folder name X and Y using Terminal. 回答1: find . -mindepth 1 -d -type d ! -name X -a ! -name Y -exec rm -r {} \+ mkdir d; touch d/f; find . -name d -delete doesn't seem to work. -mindepth 1 and -d are optional at least on OS X. Without -mindepth -1
