amazon web services - Best way to retrieve files from AWS S3 with Spring Boot? -


i'm working on spring boot app using postgresql database , s3 bucket storage images. when saving new entry i'm uploading image s3 bucket , saving name db. retrieve image s3 bucket need prepend url pattern in view this: 

<img th:src="@{'https://s3.us-east-2.amazonaws.com/mybucketname/test/'+${entry.image}}" height="256" width="256"/>

but, see image need make incoming file "test" folder public adding new policy s3 bucket this:

{ "version": "2008-10-17", "statement": [     {         "sid": "allowpublicread",         "effect": "allow",         "principal": {             "aws": "*"         },         "action": "s3:getobject",         "resource": "arn:aws:s3:::mybucketname/test/*"     } ]

}

questions:

  1. is save approach?
  2. can retrieve files in different way?

you doing fine. need make sure not give permission list contents of buckets viz. if type https://s3.us-east-2.amazonaws.com/mybucketname/test/ on browser should not list file names in folder.

as mentioned mohan; can configure cdn (in front of s3 bucket) retrieve files; improve load time customers.. configuration , cost involved , useful if have lots of geographically distributed customers.

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
