Eseguire istanze multiple di un programma (es. Mega.nz) su Windows
Usa un utente di Windows che che abbia una password e che non sia quello dal quale vuoi lanciare l’istanza.
Installa e configura il programma soltanto per quell’utente. Consiglio di sincronizzare una cartella al di fuori della cartella Utenti per evitare problemi di permessi (es. “C:\mega – NOMEUTENTEMEGA” o “D:\mega – NOMEUTENTEMEGA”).
Crea un collegamento.
Come destinazione inserisci ad esempio: C:\Windows\System32\runas.exe /savecred /user:”NOMEUTENTEWIN” “C:\Users\NOMEUTENTEWIN\AppData\Local\MEGAsync\MEGAsync.exe”
Aggiungi al collegamento i privilegi da amministratore.
Verrà richiesta la password soltanto al primo avvio.
NOTA: è bene creare un collegamento alla cartella, dato che dal programma non sarà possibile aprirla.
Da querystring a object (e viceversa) con jQuery e Underscore
Se state usando sia jQuery che Underscore, sappiate che è possibile convertire una querystring in un oggetto e viceversa con poche righe di codice.
Attualmente non esiste uno standard per la gestione degli array in HTTP GET: dipende ad esempio dai linguaggi e dai framework in uso. Qui vengono trattati PHP e JavaScript ES6, e viene considerato soltanto il tipo di array più semplice possibile che sia gestibile sia da PHP che da JavaScript.
Da query string a object
const str1 = "a=1&b=2"; // full URL is valid too
const params = new URLSearchParams(str1);
const obj = _.object(Array.from(params.entries()));
// {a: 1, b: 2}
const str2 = "a=1&b[]=2&b[]=3";
const params = new URLSearchParams(str1);
const obj = [...params].reduce((o, [k, v])=> {
const _k = k.replace(/\[\]$/, '');
return {...o, [_k]: k.match(/\]$/) ? [...(o[_k] || []), v] : v};
}, {});
// {a: 1, b: [2, 3]}Da object a query string
const obj = {a: 1, b: [2, 3]};
const params = new URLSearchParams(obj);
const str1 = (_obj => {
const parse = (arr, inArray) => arr.map(entry => {
let k, v;
if (Array.isArray(entry)) {
k = entry[0];
v = entry[1];
if (Array.isArray(v)) return parse(v, k).join('&');
} else {
v = entry;
}
return `${k||inArray}${inArray?'[]':''}=${encodeURIComponent(v)}`;
});
return parse(Object.entries(_obj)).join('&');
})(obj);// "a=1&b=2%2C3" -> a=1&b=2,3
const str2 = $.param(obj);
// "a=1&b%5B%5D=2&b%5B%5D=3" -> "a=1&b[]=2&b[]=3"
risultati precisi con .toFixed()
Se non volete più preoccuparvi di problemi come questo:
(162.295).toFixed(2)
// --> “162.29” ma dovrebbe essere “162.30”potete crearvi la vostra versione “bug free” che sfrutta la notazione esponenziale:
toFixed(n, q){
if (!Number.isFinite(q) || !Number.isInteger(q) || q > 20 || q < 0 ) {
throw new Error('toFixed needs an integer between 0 and 20 as an argument');
}
if (q === 0) {
return Math.round(n);
}
const result = +(Math.round(n + 'e' + q) + 'e-' + q);
if (Number.isNaN(result)) {
throw new Error('toFixed works on numbers written in decimal notation');
}
const int = parseInt(result);
if (result === int) {
return result + '.' + ''.padEnd(q, '0');
}
const str = String(result);
const dot = str.indexOf('.');
const dec = str.substr(dot + 1);
return int + '.' + dec.padEnd(q, '0');
}Device non rilevato da Chrome Remote Debugging
Non riuscivo a far riconoscere due telefoni, un Samsung Galaxy S4 ed un Samsung Galaxy S4 mini, finchè dopo ore di ricerche e tentativi non ho trovato questo post:
In sostanza:
adb kill-server
adb start-server
Se adb non fosse installato globalmente, dovreste trovarlo in questa cartella:
Mac OSX: ~/Library/Android/sdk/platform-tools
Pulsante rapido “Gestisci password” per Google Chrome
Per uno sviluppatore web, non avere nella toolbar del browser un pulsante per la gestione delle password è abbastanza seccante. Per Firefox esiste Secure Login, mentre per Chrome non ce ne sono.
Una soluzione è aggiungere ai preferiti la pagina delle password ( la cui url è chrome://settings/passwords ) ricordandosi che cliccandoci sopra col pulsante centrale (la rotellina) il bookmark si apre in una nuova tab. Se poi come me preferite avere un pulsante come quello delle estensioni, è possibile usare l’estensione Custom Button per crearlo.
XAMPP per Windows – Usare i Virtual Host
Se configurando un virtual host su XAMPP vi siete imbattuti nel problema “errore 403 permission denied” cercando di visitare il sito locale dal browser, la soluzione è modificare la regola per il settaggio dei permessi, che è leggermente cambiata a partire dalla versione 2.4 di Apache.
Da così:
<VirtualHost www.mywebsite.local:80> DocumentRoot "C:/xampp/htdocs/mywebsite" ServerName www.mywebsite.local #... <Directory "C:/xampp/htdocs/mywebsite"> #... Order allow,deny Allow from all </Directory> </VirtualHost>
diventa così:
<VirtualHost www.mywebsite.local:80> DocumentRoot "C:/xampp/htdocs/mywebsite" ServerName www.mywebsite.local #... <Directory "C:/xampp/htdocs/mywebsite"> #... Require all granted </Directory> </VirtualHost>
Testando i vecchi Conditional Comments su IE11
Dato che a partire da Internet Explorer 10 i Conditional Comments non sono più supportati, mi sono trovato un po’ in difficoltà andando a rimettere mano su alcuni vecchi lavori che li usavano.
Usando IE11, ho premuto F12 per far comparire gli scomodissimi Developer Tool, dopodichè sono andato nella tab “Emulazione” ed ho selezionato IE9. Risultato: il supporto ai Conditional Comments viene abilitato, ma viene rilevato IE11 (il browser in uso) e non IE9! Stessa cosa selezionando le versioni inferiori di IE.
L’ennesimo pasticcio di Microsoft (per di più su features proprietarie) non dovrebbe sorprendermi. Però mi rompe. Tanto.
Conditional Comment per il caso “qualsiasi browser tranne IE”
I Conditional Comments sono una comodissima funzionalità di Internet Explorer che permette di detrerminare la versione del browser Microsoft in uso e di conseguenza eseguire un certo codice HTML. Talvolta però i programmatori hanno l’esigenza di eseguire codice HTML nel caso l’utente NON stia usando Internet Explorer. Usando i Conditional Comments la cosa non è fattibile, visto che stiamo parlando di una funzionalità propria di IE, e che non funziona su Firefox, Chrome e compagnia bella.
Per fortuna c’è il trucco!
Sfruttando il comportamento dei parser degli altri browser è possibile ottenere una sintassi che escluda codice nel caso ci si trovi in un browser diverso da Internet Explorer:
<!--[if !IE]> -->
HTML
<!-- <![endif]-->

Fix per Lightwindow
Lightwindow 2 è l’ennesimo clone di Lightbox. Sscritto da Stickman (Kevin Miller), poggia su Scriptaculous ed è fatto abbastanza bene, perciò l’ho usato spesso. Nel corso degli anni però mi sono imbattuto in qualche bug che ho fixato, e dato che il sito ufficiale non è più raggiungibile ho deciso di postare almeno qui i fix. Fortunatamente esiste anche un mirror del sito ufficiale, così si può consultare ancora la documentazione.

'Promemoria: percorsi files esterni
Siccome quando lavoro coi files SWF, CSS e JS che caricano dinamicamente immagini o altro faccio sempre confusione coi path relativi, ecco qui la regola scritta e verificata una volta per tutte!!!
Tutti i link a files esterni sono relativi alla cartella:
- HTML: della pagina stessa
- CSS: del file CSS
- JS: della pagina che include il file js
- SWF: della pagina che include il file swf
ATTENZIONE IN PHP:
Dato il filesystem:
/index.php
/1/index.php
/1/2/index.php
/1/2/3/index.php
e dato che ogni files tranne il primo contiene l’istruzione:
include(‘../index.php’)
se da browser richiamo /1/2/3/index.php esso non arriverà a chiamare /index.php come ci si potrebbe aspettare, bensì richiamerà sempre e solo /1/2/index.php creando un loop infinito. Questo perchè fa riferimento il percorso del file “padre” di tutti gli altri (quello richiamato da browser per intenderci.)
JS Power!
