Omnia incepit cum collega suggessit me munusculum facere interretialem. Putabatur aliquid esse quasi fomes, sed pro IT hangout. Munus prorsus simplex est, subcriptio, figuram exple et ad summam perge, nempe interlocutorem et nexus tuos inveniens et novas notas amplificans.
Hic digressus sum et pauca de me ipso narrabo, ut in posterum clarius pateat, quamobrem ita insequamur.
In momento teneo positionem artificis technici in ludo studio, experientia programmandi mei C# tantum in scriptis et utilitatibus ad unitatem scribendis fundata est, et, praeter hoc, elaborationem elaborandi cum android artibus elaborandis. Extra hunc mundum, nondum electo et verso tali opportunitate.
Pars 1. Frame Prototyping
Cum constituisset quid hoc officium futurum sit, optiones exsecutionis quaerere coepi. Facillima via esset aliquam solutionem paratae invenire, in qua, sicut bubo in globo, mechanicas nostras trahere potes et totam rem publicam censuram expone.
Sed hoc non interest, nullam provocationem et sensum in hoc non vidi, quapropter interretiales technologias et methodos cum illis mutuandi studere coepi.
Investigatio incepit perspicere articulos et documenta in C # .Net. Hic varias inveni vias ad negotium conficiendum. Multae mechanismi sunt pro mutuo retis, e solutionibus plenae flexae sicut ASP.Net vel Azurei servitiis, ad commercium cum TcpHttp iungendum.
Primum cum ASP conatum, statim cassavi, in mea sententia nimis difficilis fuit ad nostram utilitatem decernendam. Non utemur etiam tertia parte facultatum huius suggesti, sic inquisitionem continuavi. Electio orta est inter TCP et Http-servatorem clientem. Hic, in Habre, incidi articulum de Quibus collectis probatisque, cum TCP nexus intendere constitui, aliqua de causa putabam me non posse solutionem crucis suggestuum creare.
Prima versio servi inclusa est nexus tractandi, inserviens contenti paginae statice, ac etiam datorum usoris. Imprimis autem constitui utilitatis causa operandi cum situ aedificare, ut postea processus applicationis MASCULI et ios hic ligare possem.

Sua essentia in eo consistit quod ope expressionum regularium petitionem in partes frangere potest. Mandatum ex cliente accipimus, primam lineam eligimus, quae modum et url petitionem continet. Deinde legitur caput capitis, quod in aciem formae HeaderName = Content adigimus, et etiam, si quis invenimus, contentum comitantem (exempli gratia, query chorda) quam etiam in similem aciem impellimus. Praeterea, parser invenit si clientis hodiernus est auctoritate sua data et salvat. Omnes petitiones clientium authenticae nullam habent potestatem, quae in crustula condita est, propter quam potest logicam ulteriorem laborem pro duobus clientibus separare et eis recta responsa dare.Bene, parva et grata lineamenta quae in separatum modulum movenda sunt, petitiones convertens sicut "site.com/@UserName" in paginas usoris dynamice generatae. Post petitionem dispensando, sequentes moduli exoriri possunt.

Labores impensas scribendi duas applicationes pro duobus suggestis reducere decrevi in ββXamarin.Forms crucis suggestum facere. Item per hoc quod est in c. Applicationem probandi factam quae simpliciter notitias servo mittit, in unum momentum interesting cucurri. Petitio ab artificio, pro ioco, in HttpClient implevi et proieci in servo HttpRequestMessage quod continet notitia ex auctoritate formae in forma json. Nihil in particulari exspectans, servo stipem aperui et petivi a machinis cum omnibus quae ibi erant. Levis stupor, conscientia omnium rerum quae transactis per 3 septimanas vesperi languidae sunt. Ad rectam notitiarum missarum reprimendam, servitorem in HttpListner convocavi. Accepta altera petitione iam inde, eam seorsum in duobus lineis codicis accepi, datam a forma KeyValuePair accepi. Parsing quaesita ad duas lineas redacta est.
Porro tentare coepi, antea non commemoratum est, sed in priore servo adhuc fabricatum in interretis elaboratum habui. Satis bene laborabat, sed ipsum principium commercii per Tcp deprimebat, nimium extra edendum erat ut commercium duorum usorum cum logging correspondentiae recte construeret. Hoc includit parsing petitionem pro nexu mutandi et colligendi responsionem utens RFC 6455 protocollo, ideoque in servo testi nexum simplicem interretialem creare decrevi. Tantum causa interest.

Servo ipso nexum statuit, responsionem clavem generavit. Seorsim etiam non habui adnotationem configurare per ssl, satis est systema libellum iam in portu debiti constitutum habere.
In latere et in situs parte nuntii clientes duo commutati, haec omnia initium fuit. Nulla magna parsers tarditatem servo, nulla exigitur. Tempus responsum ab 200ms ad 40-30ms redactum est. Et veni ad solum iudicium rectum.
Praesens exsecutionem server in Tcp mitte et omnia sub Http rescribe. Nunc consilium redesign in scaena, sed secundum diversa principia conversationis. Operatio machinis et situs conformantur et deprimuntur et conceptum communem habet, cum sola differentia quod cogitationes HTML paginas generare non indigent.
conclusio,
"Nescio vadum, caput ne mittas in aquam". Opinor, antequam opus aggrediamur, fines et proposita clarius definire deberem, necnon in studia necessariarum technologiarum ac methodorum ad exsequendum varios clientes intendere. Exertum iam appropinquat peractio, sed fortasse revertar ad disputandum quomodo quaedam rursus mihi perstrinxi. Multum in processu progressionis didici, sed plus discere in futuro. Si hoc longe legeris, tum legendi gratia.
