edit - How do I update a single value in a nested array of objects in a json document using jq? -


i have json document looks following. note simplified example of real json, included @ bottom of question:

{   "some_array": [     {       "k1": "a",       "k2": "xxx"     },     {       "k1": "b",       "k2": "yyy"     }   ] }

i change value of k2 keys in some_array array value of k1 key "b".

is possible using jq ?

for reference actual json document, environment variable file use in postman / newman tool. attempting conversion using jq because tool not yet support command line overrides of specific environment variables

actual json

{   "name": "local-stack-env-config",   "values": [     {       "enabled": true,       "key": "kc_master_host",       "type": "text",       "value": "http://localhost:8087"     },     {       "enabled": true,       "key": "kc_user_guid",       "type": "text",       "value": "11111111-1111-1111-1111-11111111111"     }   ],   "timestamp": 1502768145037,   "_postman_variable_scope": "environment",   "_postman_exported_at": "2017-08-15t03:36:41.474z",   "_postman_exported_using": "postman/5.1.3" }

here simpler version of zayquan's filter:

.some_array |= map(if .k1=="b" .k2="changed" else . end)

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
