c++ - What's the result of a & b? -

-
this awkward, bitwise , operator defined in c++ standard follows (emphasis mine). the usual arithmetic conversions performed; the result bitwise , function of operands . operator applies integral or unscoped enumeration operands. this looks kind of meaningless me. "bitwise , function" not defined anywhere in standard, far can see. i , function well-understood , may not require explanation. meaning of word "bitwise" should rather clear: function applied corresponding bits of operands. however, constitute bits of operands not clear. what gives? this underspecified. issue of standard means when refers bit-wise operations subject of few defect reports. for example defect report 1857: additional questions bits : the specification of bitwise operations in 5.11 [expr.bit.and], 5.12 [expr.xor], , 5.13 [expr.or] uses undefined term “bitwise” in describing operations, without specifying whether value or object representation in view.

python - Hierarchical indexing with Pandas -

-
i have pandas dataframe with 3 index levels , 2 columns. can see part of here: av_intensity std_dev key1 key2 time 0 0 32000 -0.005203 0.006278 32200 0.005330 0.005221 32400 0.002679 0.005006 32600 -0.000723 0.006145 32800 -0.000317 0.010467 33000 -0.006543 0.007808 33200 -0.004180 0.005070 33400 -0.006275 0.009662 33600 -0.014763 0.006938 33800 -0.029516 0.004710 the indices numbers, e.g. (0.0, 0, 32000.0) set of indices. i trying use df.ix[ 0.0, :, 32000.0] or df.ix[ :, 0, 32000] kind of hierarchical indexing doesn't work. is because indices not integer? how can kind of hierarchical indexing data frame? see advanced hierarchical indexing section in docs full explanation: http://pandas.pydata.org/panda

i want verify if object has been compiled in 32-bit or 64-bit: % readelf -h my_obj elf header: magic: 7f 45 4c 46 01 02 01 00 00 00 00 00 00 00 00 00 class: elf32 data: 2's complement, big endian version: 1 (current) os/abi: unix - system v abi version: 0 type: exec (executable file) ... since elf32 displayed, guarantee object in 32-bit mode? fat binaries aren't common or standard elf, class reliably indicate 32 vs 64 bit. figure out whether you're looking @ 32-bit x86, arm, mips, or whatever, have inspect machine field right below type field.

i'm looking algorithm provides call "shrunken convex hull" (as distinct "reduced convex hull") in 3d. defining shrunken hull, h', volume of space has, no less d distance original convex hull, h. analytically, can formed moving each plane of h inwards along normal d, computing convex hull (if exists) of resultant planes. tricky bit planes might trimmed or dropped, others may move past other planes, , entirely "snipped" out due normal reversal (if d big enough). i’m bit fuzzy on how algorithm, have badly thought out ideas below. i doing identify subset of points in dataset guaranteed no less given distance surface of original point set (which assumed convex, , have this). remove surface effects disrupting our signal in calculations doing. i'm looking name, or examples of doing this, or way compute this. ideally good-old open code great, think problem far niche. i found reduced convex hulls, seems different idea. current closest thin
