IT speaking in an informal tone, I must confess that the Recycle Bin is a feature labeled with 3 1 i: i Nutile, the Lord and the gnobile. Let's face it, too, that his real counterpart, the household rubbish bin is just a transit to finish in the landfill, and no one would dream of using it as a container to give the possibility to retrieve the trash after a change of heart.
But that information has become trash now a major placebo effect: it makes us feel safe and relaxed while using the computer. And that's why it was labeled with the third: a programmatic commitment is sufficient to show a "chic" dustbin iconified on the desktop or dock.
But ... I am a confident person, when I delete files using the awkward key combinations Shift + DEL to throw directly into the landfill (the neglect of bytes / dev / null) ... but with time I have softened and my basket is swelling for the decomposition of giga stored behind an icon that could be representative of our age. The terabyte of my computer, reflecting well the opulence of this era, it makes me seem unnecessary effort trying the option empty cestino , così la montagna artificiale di “monnezza” si alza di giorno in giorno, fino a quando, un giorno, ci verrà a trovare Caronte per traghettarci laggiù.
Quel giorno, per me, è arrivato; con il file manager aperto su una cascata di directory, SitoA , SitoB , SitoC , SitoD ..., scopro di aver cancellato erroneamente il file index.html sbagliato. Caronte è arrivato con un traghetto a vapore 2 . La traversata dell' Acheronte è un viaggio di riflessione; i miei pensieri, all'ombra dell'immensa montagna che si staglia horizon, they search the last time I emptied the trash ever. Do a generous tip to Charon and say, "Dear 3 wait for the return journey. I go and come back, "but his dark eyes I'm not reassured. climbs the mountain of waste sorted in alphabetical order and when I come up to the ind .. am, of course, 52 files with the same name. And here I find the weight of the 3: programmers of my Desktop Environment have neglected, ignored and snubbed the usefulness of the basket and you are clearly assigned to a mere placebo effect so as not to develop anything inside that tolla 4 disegnata con un'impegnativa abilità grafica. Mi si fa chiara l'ombra dello sguardo di Caronte: nulla qui mi aiuta, non c'è segnata alcuna data di cancellazione, il percorso originario del file... non c'è nessun suggerimento per capire quale file dovrei ripristinare. Per fortuna, la disperazione che rimbalza nella mia scatola cranica, scopre il ricordo riposto di aver conservato un vecchio backup nel server. Corro lontano da quella montagna, non prima di aver incendiato quell'inutile ammasso di byte, e mi rifugio nelle braccia del mio backup.
Cosa mi fa arrabbiare? KDE 4 sta giocando con i plasmoidi trascurando i servizi base. Gnome 2.32, after 14 years, announces, as if it were an innovation of the second millennium:
When you view the contents of the basket is a new button in the information bar that allows you to restore selected files. In the basket are also indicated the original location of deleted files and the date on which it was removed .
Hey, where are the new and useful services that would turn trash into something useful? I do not want a list of dry tons of files, I would be able to view / search for files deleted on the basis of logical criteria (history of erasure, the type of file ,...), features to help me manage that discarica, come potrebbero essere, ad esempio: svuota i file più vecchi di XXX, svuota i file più vecchi di XXX automaticamente, recupera i file (selezionati, o conformi ai criteri di una ricerca) in una cartella di destinazione specificata, ecc...
Sono esigente? Sono figlio del 2.0, dove quel 2 sta a indicare che i ruoli sono cambiati : non è più l'utente che deve capire e adattarsi al computer.

Espressamente per voi le Espressioni regolari for dummy
If you the regular expressions may appear jargon to define those dialogues were born to be said but to be heard, "Hey, how are you?" "There ' is bad, and you? ", perhaps you should reconsider your definition when you have a program that wipes out in front of his eyes while he says, sounding sullen, dull drivel that those are routine.
To make you understand the resentment of the programmer to you, think about the harmony you perceive when you can say "I have regular bowel " and now, after entering into this harmonious state, think of the feeling of seize power by ' expression interlocutor after telling him "I did the Stelvio pass in cycling," Well if you add up the two sensations you might have a vague idea of \u200b\u200bthe pathos that the programmer lives against and regular expressions of his hatred towards you because not participating in the same emotion and idolatry on such magnificence.
Already, the programmer when he hears the expression regular expressions and estasiaticamente inevitably sees before one's eyes the superlative power of strings also this:
As you can see from the above-quoted string, the regular expression represent the most powerful and fastest way to do lexical analysis of a text.
If at this point you are still in the oblivion of that is to say?? evidentemente non avete minimamente colto l'opportunità di poter lavorare meno ...e meglio (ma quest'ultimo aspetto forse interessa a molti meno).
La fatica ai muli
Vi sarà sicuramente capitato di soffrire per un vostro collega, o per voi stessi, quando lo vedete ridotto a un mulo automa, ad esempio, mentre corregge manualmente la punteggiatura di un elenco con centinaia di voci.
Non so a voi, ma a me capita spesso di dover correggere la punteggiatura errata dei punti elenco (ma io non soffro), già perché sovente gli autori dimenticano che un punto elenco dovrebbe avere un'adeguata punteggiatura: ogni voce termina con il punto e virgola tranne l'ultima che termina con il punto.
Un esempio per tutti Moltissimi editor di testi offrono appunto l'utilizzo delle espressioni regolari, ad esempio se con Writer di OpenOffice dobbiamo provvedere a inserire la punteggiatura dimenticata (il punto e virgola alla fine della voce) in un mastodontico elenco, invece di chinare la testa e digitare a mo' di uomo robotizzato i punti e virgola per ogni voce per le prossime ore possiamo semplicemente e velocemente selezionare l'intero elenco, tranne l'ultima voce (dove metterete il punto), e dal menu Modifica scegliere il comando Cerca e sostituisci . Nella finestra che comparirà dovrete cliccare sul pulsante in basso Other Options and put the check mark:
only in the selection ;
Regular expression.
Now, having enabled the regular expressions, you can pick the rules of lexical analysis. In our case, in Search we will need to tell him to seek the end of each line, to do this simply type the character $ which indicates the end line. Then in the Replace with field , we tell him to put the semicolon, but, importantly, we must also tell him not to remove the newline, so type the following combination Character:
\\ n
where ; is the character that will be inserted (replace) at each end of the line, and characters \\ n specify to keep (or replace) the end of the line in order to maintain the vertical structure list (otherwise we would end up all the items in a single horizontal line).
And if ...
And if the author turns to rookie of the text had to be corrected manually entered the numbers in front of the item in the list, how to remove it to leave (or enter) only bullet formatting to the editor? Simple: by using le espressioni regolari !
Compiendo le operazione poc'anzi menzionate, nel campo Cerca scriveremo:
^[:digit:].
Mentre il campo Sostituisci con lo lasceremo vuoto. Ehi, non dimenticarti infine di cliccare sul pulsante Sostituisci tutto !!

Quando la pigrizia ti impedisce di leggerti l'help
Ti riporto la pagina di OpenOffice che spiega i caratteri usati per scrivere le espressioni regolari in Writer (ma impara a leggerti gli help):
Carattere
Effect / use
Any character represents the character data unless otherwise noted.
..
Represents any single character except the characters a line break or paragraph break. For example, search for "R.ssi" returns both "Smith" and "Russians."
^
Find the search term appears only at the beginning of a paragraph. Any special items (such as empty fields or character anchored frames) at the beginning of a paragraph are ignored. Example: "^ Mario."
$
Find the word sought if it appears at the end of a paragraph. Any special items (such as empty fields or character anchored frames) at the end of a paragraph are ignored. Example: "Mario $".
* Identifies the absence or presence of one or more of the characters preceding "*". For example, "Ab * c" finds "Ac", "Abc", "ABBC", "abbbc" and so on.
+
Identifies one or more characters before "+". For example, "AX. +4" Finds "AXx4" but not "AX4". will always find the longest string corresponding to the search pattern in a paragraph. If the paragraph contains the string "AX 4 AX4" the entire passage is highlighted.
?
Finds zero or a single occurrence of the characters before "?". For example, "Texts?" return "Test" and "Text", and "x (ab the key combination Shift + Enter. To transform the line break in a paragraph break, enter
\\ n
boxes
Search and Replace with
, then execute a search and replace.
\\ n in the text box
Search
represents a line break was inserted with the key combination Shift + Enter.
\\ n in the Replace With text box
is a paragraph that can be inserted with the Enter key. \\ t Represents a tab. You can use this expression in the Replace with box . \\>
Find the search term appears only at the end of a word. For example, "love \\>" finds "branches," but not "friends."
\\ \u0026lt; Find the search term appears only at the beginning of a word. For example, "\\ \u0026lt;love" finds "friends" but not "branches".
^ $
Locate an empty paragraph.
^. Search
the first character of a paragraph.
& o $ 0
When you make a replacement, adds the string found by the search criteria in the Search box
al termine che compare nella casella
Sostituisci con
.
Ad esempio, se inserite "cornice" nella casella
Cerca
e "&finestra" nella casella
Sostituisci con
, la parola "cornice" viene sostituita con "cornicefinestra".
Immettendo il carattere "&" nella casella
Sostituisci con
potete modificare gli Attributi o il Formato della stringa individuata dai criteri di ricerca. [abc123] Rappresenta uno dei caratteri compresi tra parentesi. [a-e] Rappresenta i caratteri compresi tra le lettere "a" ed "e".
[a-eh-x]
represents the characters between the letters "a" and "e" and between the letters "h" and "x".
[^ as]
represents the characters between "a" and "s".
\\ XXXXX
represents a special character by its hexadecimal code to four digits (XXXX).
The code for the special character depends on the font used. To view the codes, choose
Insert - Special Character
.
this trova sia "questo" che "quello".
{2}
Definisce il numero di ripetizioni del carattere che precede la parentesi graffa aperta. Ad esempio, "mol{2}e" trova "molle".
{1,2}
Definisce quante volte può ripetersi il carattere che precede la parentesi graffa aperta. Ad esempio, "mol{1,2}e" trova "mole" e "molle".
{1,}
Definisce il numero minimo di volte che il carattere che precede la parentesi graffa aperta può ripetersi. Ad esempio, "mol{2}e" trova "molle", "mollle" e "mollllle".
( )
Nella casella Search
:
Defines the characters in brackets for reference. You can then refer to the first referenced in the active with "\\ 1" per second "\\ 2" and so on.
For example, if your text contains the number 13487889 and run a search using the regular expression (8) 7 \\ 1 \\ 1, is found "8788".
To group terms can also use (), for example, "a (bc)? D" finds "to" or "abcd". In the Replace with box
:
Use the $ (dollar) instead of \\ (double backslash) to replace references. $ 0 used to replace the entire string found.
[:alpha:]
Rappresenta un carattere alfabetico. Per cercarne uno usate [:alpha:]+.
[:digit:] Rappresenta una cifra decimale. Per cercarne una usate [:digit:]+.
[:alnum:]
Rappresenta un carattere alfanumerico ([:alpha:] e [:digit:]).
[:space:]
Rappresenta un carattere di spazio singolo (ma non altri caratteri di spaziatura).
One night I woke my wife to tell her that the conception of File Manager is a mistake that makes us still live in the midst of the dinosaurs and that night I found myself to sleep out in the cold, probably in the company of dinosaurs not extinct.
possible that a misconception is keeping alive the prosperous culture of the "club" as a technological tool most used in the twenty-first century? And my wife does not understand the gravity of this revelation at night?
I still remember the words of my professor: "The HardDisk is like a wardrobe, if you put so much stuff you have to learn to be ordered" ... otherwise you will not find anything: it was a tacit warning that the final I felt back in the '90s (and the harddisk was 40 Mb.)
Case History 1: When the memory betrays
I took the computer in hand after a week of illness, because I had to send a slide to a customer that I had made that last day in office with his head stuck in the loop of influence. Well, I did not remember the name of the file, and especially in which the umpteenth directory / subdirectory that build digital city I had saved my HardDisk. Nothing serious, just rely on the invaluable research tool Find File ... your File Manager. Not knowing where to look and even the name and file extension (I do not remember if I had saved in pdf, ppt and odp), I did a search simple and focused: search all files modified between 23 to 25 October 2010
only associated directory Home comprensivo delle sottodirectory
e l'autore sono IO (informazione aggiunta per mero scrupolo)
Sotto l'effetto dell'influenza, in quei tre giorni lavorativi avrò al massimo manipolato una trentina di file, pertanto i parametri di ricerca mi sembravano più che adeguati per trovare velocemente il file in questione. Invece no! Lo stolto FileManager mi risponde con un incredibile e disumano elenco di 69'844 file trovati!!!!
Perché? Perché è stupido, il File Manager ha processato la richiesta in modo elementare, matematico, fisico ma non “umano”. Nella sua ricerca ha considerato anche tutti i file modificati/creati in my name from the system through various programs and services (eg temporary files, backups, cookies, settings ...); as a dear friend would say such
Foffi which ignore the existence
!
Case History 2: ephemeral certainties
E 'Friday night, completed a presentation on the morning following my colleague the emailing and run home.
sweaty Saturday morning I received a phone call that resonates with the words "the attached file is corrupt!"
Strange, control the attachment of the email and resubmission. Soon, a new phone even more wet gutter with these words "The attached file is corrupted !!!".
Encapsulates the file in an archive 7zip and resubmission. Shortly after the same call: "The attached file is corrupt!". I support him and the file on the server I download it via FTP, and here is his worried voice: "The attached file is corrupted !!!". Something eludes us, and I inquire about his only words: "The attached file is corrupted !!!". She then discovers that his FileManager (I mention no names) does not recognize the file type, therefore, finds himself unable to perform the correct application to open it. In fact, in the name of the file was missing (for my careless omission) extension: the old, hoary and labile how to identify the file through i nomi. Dovete sapere che i FileManager più seri riconosco il tipo di file semplicemente analizzando la prima riga contenuta in esso, ma.... quante brutte abitudine sono dure a morire e pesano sull'utente ignaro! Case History 3: nomi a fantasia sequenziale Trovo un piccolo ritaglio di tempo per manipolare le foto del compleanno di mio figlio. Salvo la prima e il programma mi chiede il nome del file. Digito “Compleanno di Mario”. Salvo la seconda è mi chiede il nome, il soggetto è sempre il medesimo ergo gli attribuisco lo stesso nome “Compleanno di Mario”, ed ecco impuntito il geniale File Manager mi avvisa solerte di un conflitto con un altro file che ha nome uguale.
Unfortunately you can not communicate with the File Manager, otherwise I would have tried to explain that this is an image with the same subject, and if he is confused because I do not worry I'll tell by the preview of ' image. But no, I bent to the imagination of sequential name (pippo1, pippo2, pippo3 ...) I strongly suggested that the File Manager as
evolved.
File Manager: the ancient wardrobe If you ask what is the application you use more could you really answer? Text editors, graphics programs, web browser, email client .... no! is certainly the unnamed File Manager (Explorer, Finder, Dolphin, Nautilus ... to name the most famous). It should be a software specially designed to mediate the tasks of the filesystem (the one that handles any data onto the hard disk) with your needs in order to facilitate the common file operations.
I want to show a gallery of screenshots of some of the most popular and current File Manager:
is 25 years, yet, as you might guess from the pictures, the 'evolution of this basic software, the File System, is reduced to mere emotions such as color graphics, icons, transparency ... to the folk management in 3D like this:
File Manager: da armadio a ..comò? Finally, perhaps, its interface will finally dress the role of mediator between the user and the file system. I know ... forgetting the archaic navigation for directories, separately in the first real user files from all the others, showing recently used files, a classification by activity (where the same file may appear in more activities without those hated / misunderstood "links"), a chronological classification by file type, and a nice text box to compose simple and functional questions ...
short, something like (grab the provocation):
Software, ideas and prototypes there are so many .. but lacks the program that puts together all this stuff to review and re-establish the concept and using the File Manager.
