Netcdf java library for reading HDf5 error -


i newbie netcdf library , using read metadata hdf5 file in java. after reading, thought netcdf decent enough library use, using it.

however in first step when try read file throws error 

logger.debug("inside try"); //inputstream filestream = new fileinputstream(h5file);                 //parser.parse(filestream, handler, metadata);    logger.debug("path :"+ h5file.getpath());    netcdffile hf5file = netcdffile.open(h5file.getpath());        logger.debug("got netcdfile");

i assuming problem occurs when try open , says :

inside try 13:42:04.393 [main] debug e.k.n.c.m.e.hdf5metadataextractor - path :/var/www/webdav/admin/1151/data/xxxx.h5 13:42:04.495 [main] debug ucar.nc2.netcdffile - using iosp ucar.nc2.iosp.hdf5.h5iosp 13:42:04.544 [main] error ucar.nc2.iosp.hdf5.h5header - shape[0]=0 must > 0

my hd5f 2 dimensional array of integers, not interested in array such metadata group associated file.

netcdf-4 creates hdf5 files, it's true. hdf5 library can read hdf5-formatted files produced netcdf-4, netcdf-4 cannot read arbitrary hdf5 files.

either have found bug in netcdf-java, or have odd hdf5 file. have confirmed file not corrupted in way? things try: - use c utility 'ncdump -h' inspect header - use hdf5 c utility 'h5dump -h' inspect file via hdf5

if both of commands give sensible output, issue might rest netcdf-java.

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
