  • WISP Manifesto

    We talked about ”Web applIcation Service Provider” (WISP) in the past days. So what are the specification for a Service Provder wanting to be a WISP?

    Let’try to sketch them together:

    WISP Hypothesis

    • A WISP must offer a set of XML-RPC API (WISP API) to configure the services. They must be simpler than SOAP, and must support at least two languages picked from  Python,Ruby,Java,PHP, Perl.
    • WISP API should be provided always in SSL way.
    • WISP API specification will be provided on subsequent articles
    • WISP must provide a minimal set of LAMP applications, like WebMail, CMS (i.e. Wordpress). Also WISP must provide at least one "dashboard" web interface to set up a dashboard for the WISP API
    • For simplicity, the web application are deployed as  two tiered: database tier and web tier. Anyway you can build complex system connecting a lot of 2-tier application
    • On the database tier, WISP must give at least one Relational Database (like MySQL or PostgresSQL) and one NoSQL solution, altrought NoSQL forest is a bit tricky.
    • About email, at least an IMAP server and SMTP server must be provided
    • It should be possible to define "logical user" to segregate email mailboxes and web application
    • The amount of RAM allowed to be consumed by application should be considered only on the application tier. Database and webmail will be offered on a "best effort" base, with clear defined limits. For special needs, a "private" database instance could be installed
    • The Service Level Agreement (SLA) should be at least 99.99%
    • WISP has the freedom to choose the underling Operating System. By the way, the web application should try to be agnostic (even if Linux is always the first choice for a LAMP stack)
    • WISP must provide bandwidth and disk space in a very cheap way. For this reason, the "usage meter" should be easy to compute and very liberal on disk space, while very strong on single application memory usage

    Speriamo che questa manovra non sia così pessima come appare…ho seguito personalmente la conferenza stampa di venerdì sera, e sono qui a darvi le mie impressioni, dopo doverose riflessioni e la lettura dei maggiori quotidiani italiani.

    Leggiamo su Repubblica, che la manovra in atto prevede 45 miliardi aggiuntivi in due anni.

    http://www.repubblica.it/economia/2011/08/12/dirette/crisi_italia_12_agosto-20347856/?ref=HREA-1

    Per fortuna la memoria storica di Wikipedia e di Repubblica (http://www.repubblica.it/online/fatti/rifondazione/prodi/prodi.html) ci ricordano che nel 1996  fu varata una finanziaria di 62.500 miliardi di lire, cioé circa 31 miliardi di euro al cambio fisso. Quella manovra fu varata dal governo prodi per “entrare in Europa” e fu considerata un vero salasso; tale “contributo straordinario” non fu completamente restituito due anni più tardi.

    Ora si parla di un “addon” di 45 miliardi in due euro, e da più parti si dice che sia la manovra più grande della Repubblica.

    E’ oramai da più di una settimana che si parla della crisi dell’Italia. La borsa è continuata a cadare in picchiata, tanto che mercoledì 10 agosto Milano ha perso il 6,6% dopo reiterati ribassi. E’ stato anche il mercoledì nero della Francia, con voci di donwgrading del debito francese, per ora rimaste infondate.

    E’ difficile fare un’analisi approfondita, certo è che il primo ministro si è mosso velocemente, ma ha tradito una preoccupazione su cui sicuramente i mercati hanno speculato.

    La fretta di farsi trovare preparati ha creato voci confuse che hanno fatto assimigliare il governo Berlusconi al secondo confuso governo Prodi. All’inizio si è detto che non si sarebbero aumentate le tasse, chiodo fisso del nostro premier.

    In realtà la situazione è così grave che alla fine risulta che verranno aumentate sia le tasse (con una specie di patrimoniale mascherata da “eurotassa”) sia ristrutturate le pensioni.

    Quali sono le conseguenze? E la crisi è reale? Vediamolo assieme.

    Archimedes (287 BC) said “give me a place to stand and I will move the earth”.

    Apple, after decades of lack of decent garbage collection to Objective-C, seems to say “I will give an ARC to exit to the dark hand-made memory allocation”.

    Let’see how.

    Functional Programming

    Because of the success of my article on java closure, I have decided to write another article on functional programming.

    In the last year functional programming is waving back to us, for a lot of reason. Let’s summarize the facts:

    Functional programming is based on the core concept of pure function. The main advantages of functional programming is the lack of side-effects, at least at the syntax-level of the language.

    At Gioorgi.com we are not a true cloud fan, and reality is going on to collect proofs for us…

    On June 20, 2011, Dropbox had a serious security bug. It was possible to login to an account with “a wrong password”. Like to say Dropbox account system was naked, because “a small number of users[…] could have logged into an account without the correct password”!

    I Fatti

    Pisapia, il candidato di sinistra (e non tanto di centro Sorriso ha vinto a Milano con il 55,1% delle preferenze.

    A Napoli, è stata premiata una coalizione vicina a quella uscente ma distinta, e De Magistris con oltre il 65% delle preferenze avrà parecchia liberta di manovra poiché potrà contare su una maggioranza solida, composta da persone fedeli al suo partito.

    Pisapia è stato scelto durante le primarie del centro sinistra, ed ha battuto il candidato moderato Boeri.

    L’Italia dei Valori, di cui fa parte De Magistris, non ha mai risparmiato a Berlusconi una critica feroce e circostanziata.

    Why your IoC container could be a pain for you, young Padawan

    Inversion of Control (IoC) is a very good idea.

    But as the clever Joel Spolsky  noted, sometimes you need to be a super-natural hero to use it:

    … I try not to be judgemental (HAHA!), but I think that people who use IoC containers are (A) very smart and (B) lacking in empathy for people who aren't as smart as they are. Everything makes perfect sense to them, so they have trouble understanding that many ordinary programmers will find the concepts confusing. It's the curse of knowledge. The people who understand IoC containers have trouble believing that there are people who don't understand it. …
    I have trouble using Spring in at least two projects. On the third, it was a disaster, because a single software-architect-guy keeps passing around the Spring context factory as method parameter, getting beans from it!

    F# is a Microsoft research Language. F# is riding the functional revenge way of the last years. F# is a mixed approach, because some variables can be modified. It borrows a lot of things from Haskell and OCaml  (Wikipedia dixit). F# is not used like Erlang or Haskell but it could be installed with Visual Studio 2010, and as a separate visual studio plug-in. If you need some functional stuff on your .NET architecture,  F# can be your friend.
