overview: have figured out how allow users upload multiple images amazon s3 using node, express & multers3. code shows solution below. working well. issue on edit route. want users able edit or delete images. far way have been able have new images override previous filepaths. this big problem because means user has reupload every single image every time try edit post. not good. think solution might create images array instead of having individual image paths. appreciate advice. i've seen code creating array local storage i'm not sure how alter work amazon s3: if(req.files.length) { for(var = 0; < req.files.length; i++) { updatedlisting.moreimages.push() // needs push amazon s3 here somehow. } updatedlisting.save(); first show "listings" mongoose model: var listingsschema = new mongoose.schema({ name: string, description: string, image: string, image2: string, image3: string, image4: string, image5: string, author: { ...

so have couple of questions re: private memory limit in iis using c# web app. when set private memory limit 0, per docs here should have no limit. saw behavior app trigger iis reset when reaching approximately 60% of machine ram seems counter intuitive. grok? the second issue expected behavior when private memory limit set value exceeds amount of ram available on machine. co-worker solved above problem setting private memory limit above system memory , did perform well. seems have ramifications proper gc times. for example if system ram 32 gb , memory limit set 35, not trigger gargbage collection when gets close 32 because thinks can 35? or guaranteed garbage collection happen before then? additionally requires config change if ever change size of machine (we aws shop can happen @ relatively high frequency).

i want create online app between 2 players , join , find each other simple question-answer app , more thousand people can join server. it's better use firebase or create web server host ... (i'm interesting web servers)i mark correct can answer thanks the choice between firebase , web-server solely based on needs of application , on skills. firebase provides features of real-time database, authentication, storage, notifications, hosting etc. without server-side coding , other options makes easy integrate app. however, if app requirements above free usage quota of firebase, have pay services. since need server more thousand people, have pay firebase services. also, if app complexity increases, firebase may or may not able cater needs of app. on other hand, custom server have options enough app. however, creating custom server hard, depending on skills. require more maintenance firebase.

suppose have row matrix [a1 a2 a3 a4 .. an] , wish achieve each of following in matlab 1) 1+a1 2) 1+a1+a2 3) 1+a1+a2+a3 4) 1+a1+a2+a3+a4 .... 1+a1+a2+...+an how shall them? this purpose of cumsum function. if a vector containing elements [a1 a2 a3 .. an] then b = cumsum([1 a]); contains terms searching for. possibility is b = 1 + cumsum(a); edit if don't want use built-in function cumsum , simpler way go for loop: % consider preallocation speed b = nan(numel(a),1); % assign first element b(1) = 1 + a(1); % loop = 2:numel(a) b(i) = b(i-1) + a(i); end or, without preallocation: b = 1 + a(1); = 2:numel(a) b(end+1) = b(end) + a(i); end best,
