It feels to me that those calculations are always too simple, and wrong as well. Multiplying maximum server power usage times maximum dirty electricity generation CO2 emission gives overstated results. There is a huge drive for lower power consumption (because electricity in a data center is VERY expensive), to move datacenters to cooler areas, to power them with clean, renewable electricity. BTW, it seems that I did not fully understand the story about the left-pad.io library, here is one writeup: Rage-quit: Coder unpublished 17 lines of JavaScript and “broke the Internet” Dispute over module name in npm registry became giant headache for developers http://arstechnica.com/information-technology/2016/03/rage-quit-coder-unpublished-17-lines-of-javascript-and-broke-the-internet/ Quite interesting & food for thought. > Phil > > On Thu, Mar 24, 2016 at 8:58 PM, Sven Van Caekenberghe <[email protected]> wrote: > This is a really great joke: > > > http://left-pad.io/ <http://left-pad.io/> > > But should you feel the need to implement this extremely valuable web service > yourself, here is how you could do it in Pharo (error handling is not 100% > bullet proof, this is just a quick demo, but you get the idea): > > 'paddin'' oswalt' padLeftTo: 68 with: $@. > > (ZnServer startDefaultOn: 8080) > onRequestRespond: [ :req | > | str len ch | > str := req uri queryAt: #str ifAbsent: [ '' ]. > len := req uri queryAt: #len ifAbsent: [ '' ]. > len := Integer readFrom: len ifFail: [ 0 ]. > ch := (req uri queryAt: #ch ifAbsent: [ ' ' ]) first. > ZnResponse ok: (ZnEntity text: (str padLeftTo: len with: ch)) ]. > > ZnClient new > host: #localhost; > port: 8080; > queryAt: #str put: 'paddin'' oswalt'; > queryAt: #len put: 68; > queryAt: #ch put: $@; > get. > > $ curl 'http://localhost:8080/?str=paddin%27%20oswalt&len=68&ch=@' > > Of course, if you are really going this into production, you'll have to pay > me and Pharo the necessary royalties ;-) > > Sven > > PS: Returning a JSON (which does not really make sense here) is left as an > exercise. > > > >
