Upgrading Firefox Portable

from portableapps.com:

To upgrade to a newer version of Firefox Portable, just install a new copy of Firefox Portable right over your old one. All your data will be preserved.

• If you're upgrading from Portable Firefox (older name and directories), make a copy of your existing profile folder within the PortableFirefox\Data\profile directory on your portable drive.
• Then download the new version of Firefox Portable and copy your profile from the old version into the new version within FirefoxPortable\Data\profile.
• If you added any plugins or searchplugins, you should copy those directories as well (PortableFirefox\plugins to FirefoxPortable\Data\plugins and PortableFirefox\firefox\searchplugins to FirefoxPortable\App\firefox\searchplugins).

Cuesheet Processor

Cuesheet Processor (CueProc)

Introduction
Cuesheet Processor (CueProc) is a command-line tool for converting audio CD images into another format such as WAV, MP3, Ogg Vorbis, MP4, MPC, WMA, etc.

The functions of this tool can be summarized as follows:

• Parse a cuesheet (a .cue or audio file with the cuesheet embedded). Field values in a cuesheet (e.g., TITLE, PERFORMER, REM DATE, etc) will be used by the latter job.
• Read audio data in a CD image (supported format:

FLAC, Monkey's Audio, WavPack, and WAVE).

Extract tracks in a CD image to individual WAVE files.

Execute an external encoder with predefined command-line arguments for each track.

CueProc sets appropriate command-line arguments (e.g., naming for output files, tagging, etc) automatically by specifying an output plugin

Execute an external encoder with configurable command-line arguments.

Send audio stream of each track to STDIN of the external encoder.

Enumerate cuesheets recursively under a directory.

Process multiple cuesheets at a time, which is useful for converting an audio collection into a lossy format.

Skip encoding when the corresponding output file exists, which is useful for converting new CD images only.

CueProc is the successor tool to

Audio CD Image Reader (ACDIR) and LAME with cuesheet input.

Audio CD image and cuesheet
An audio CD can be represented by an audio CD image that usually consists of a single audio file (e.g., CDImage.wav for an uncompressed image; CDImage.ape for an image compressed losslessly by Monkey's Audio) and cuesheet (e.g., CDImage.cue).

The portion of an audio file stores the audio data of the entire CD.

A cuesheet (e.g., CDImage.cue) describes a track layout and supplementary meta-data (e.g., CD-TEXT). Being free from C1/C2 errors and the ambiguity of pre-gaps, audio CD image is an ideal solution to archive audio CDs without quality loss.

An audio CD image can be generated by Exact Audio Copy with a menu item, "Action" - "Copy Image & Create CUE Sheet".

A number of CD writing software such as CDRWin, Nero, burnatonce can reproduce the original audio CD from an image.

Some software audio players such as foobar 2000 and Soud Player Lilith can play CD images.

A network audio solution, SqueezeBox combined with SlimServer, turns audio CD images in a HDD into a posh music jukebox with huge amount of CDs.

However, audio CD image is not suitable for portable audio players since the size per an image is far from portable (ca. 300-700MB). Thus, we need a method to convert audio CD images to another portable format, e.g., MP3, Ogg Vorbis, MP4.

Nowadays, a number of tools can perform this job:
foobar 2000
Sound Player Lilith
DAEMON Tools (IMHO it's too much to mount an CD image only to use Exact Audio Copy again for compressing )
Please consider these tools if you prefer GUI. If you want a command-line tool for this job, CueProc is what you've been looking for.

Re: Possibility of a portable version/modification?

by Kreator on Sun Nov 04, 2007 7:02 pm

As far as I know, there's no portable version of VUPlayer. But you can use registry import/export operations to load/save the player settings.Make 2 files on your removable drive:

Save.bat:

reg export HKCU\Software\VUPlayer Settings.reg

reg delete HKCU\Software\VUPlayer

Load.bat:

reg import Settings.reg

That's one simple way to carry your
setting from one PC to another. If you don't want to erase the player settings
forom the registry, delete the second line of Save.bat file.

SvcHost.exe

tratto da xtremecomputing:

The Svchost.exe file is located in the %SystemRoot%\System32 folder.

At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load.

Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services.
Therefore, separate services can run, depending on how and where Svchost.exe is started.
This grouping of services permits better control and easier debugging.

Svchost.exe groups are identified in the following registry key:
KEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost.

Each value under this key represents a separate Svchost group and appears as a separate instance when you are viewing active processes.

Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group.

Each Svchost group can contain one or more service names that are extracted from the following registry key, whose Parameters key contains a ServiceDLL value:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Service.

To view the list of services that are running in Svchost:

Click Start on the Windows taskbar, and then click Run.

In the Open box, type CMD, and then press ENTER.
Type Tasklist /SVC, and then press ENTER.

Tasklist displays a list of active processes.

The /SVC switch shows the list of active services in each process.

For more information about a process, type
the following command, and then press ENTER:

Tasklist /FI "PID eq processID" (with the quotation marks).

ClearType

Sul sito di Microsoft trovi il tuner online.

Microsoft ClearType is an unprecedented innovation in font display technology that dramatically improves font display resolution and marks a genuine breakthrough in screen readability.

Per attivare il ClearType anche nella schermata di Logon bisogna procedere con la modifica del registro di Windows.
Dal registro di Windows modificare le seguenti chiavi: 

HKEY_USERS\.DEFAULT\Control Panel\Desktop\FontSmoothing (di tipo STRINGA)

HKEY_USERS\.DEFAULT\Control Panel\Desktop\FontSmoothingType (di tipo DWORD)

Assicurarsi che entrambi i valori siano impostati a 2.

In questo modo il ClearType sarà attivato per ogni utente e sulla schermata di Logon di Windows XP

Il tool ClearTweak

allows you to change the contrast setting of the ClearType® setting for Windows XP. ClearType® is designed to enhance LCD displays. It may appear slightly blurry on standard desktop monitors.

Protezione di files e cartelle

Per impostare i diritti a una cartella occorre cliccarci sopra con il tasto destro del mouse, selezionare “Proprietà” e successivamente la scheda “Protezione”.

In Windowx XP Professional questa è disabilitata di default. Per abilitarla accedi alle OPZIONI CARTELLA dal menu STRUMENTI di qualsiasi finestra aperta.Seleziona la scheda VISUALIZZAZIONE e togli la spunta all'opzione “Utilizza condivisione file semplice".
In utenti e gruppi compare la lista degli utenti che hanno i diritti di accesso alla cartella.Di default Windows imposta “Everyone” come utente predefinito (tutti gli utenti hanno accesso alla cartella).Se si intende impostare dei diritti per la cartella è bene eliminare l’utente “Everyone” e aggiungere i vari utenti, impostando i vari diritti.

Le autorizzazioni negate prevalgono su quelle concesse.

Un utente amministratore ha accesso alle impostazioni di protezione, anche se non ha accesso alla cartella: in questo caso, pur non potendo accede direttamente alla cartella, può sempre modificarne le impostazioni di accesso e ridefinire i diritti.

Windows XP Home ha funzionalità ridotte rispetto a XP Professional, e occorre accedere alla console per poter concedere privilegi di accesso alle cartelle.
Avviare il sistema in modalità provvisoria con supporto di rete: in tale modalità tra le proprietà della cartella compare la voce “Protezione”. Impostare i diritti e riavviare.

Oppure

Al prompt di comandi:
NET SHARE informa sulle condivisioni esistenti.
NET SHARE "nome cartella" condivide la cartellaCACLS "nome cartella" /G "nome utente" (R)(W)(C)(F) /E /T

In caso di problemi rimuovere la conndivisione con
NET SHARE "nome cartella"/DELETE

portable Firefox

Il sito MozillaZine offre precise indicazioni in merito ai files che a vario titolo memorizzano le impostazioni dei singoli profili.

Sometimes when you have problems with Firefox and can't figure out what's wrong, it's easier to create a new profile and transfer any data you want to save, rather than keep trying to fix your existing profile.

It's recommended that you only copy data that would be a lot of work to recreate (such as bookmarks, passwords, and cookies) to the new profile, and that you re-install any extensions and themes rather than trying to migrate them. Its frequently quicker to re-install or re-configure something than to spend time debugging what you did wrong.

firefox.exe -P per accedere al Profile Manager.

Add-ons

• extensions.ini
• extensions.cache
• extensions.rdf

Configurazioni relative a temi ed estensioni. NON copiare

Delete the extensions.ini, extensions.cache and extensions.rdf files in the directory. They will be regenerated when you start Firefox. This avoids potential problems due to old paths. A few extensions store data in additional files in the profile, usually at the top of the directory. You'll need to move them separately.

Bookmarks and browsing history

• bookmarks.html
• history.dat
• places.sqlite (dalla release 3.0 in poi) li sostituisce entrambi.

Cookies

• cookies.txt (Cookies can be used to keep you logged into web sites you logged into before)
• hostperm.1 (Cookie exceptions)

Download actions

• mimeTypes.rdf (What action to perform when downloading certain types of files: save or open with a specified application)

Form history

• formhistory.dat (Autocomplete entries for web forms and the search bar)

Permissions

• hostperm.1 (cookie, image, and extension install permissions)

Preferences

• user.js (an optional file)
• prefs.js

You may need to manually edit the paths in prefs.js to reflect the new profile location. If the new profile doesn't have the same extensions, you may have some unused preferences set by those extensions, but that usually doesn't harm anything.
Profox configuration files.

Saved passwords

• key3.db (Key database for passwords)
• signons2.txt (Saved passwords)
• cert8.db (Security certificates used by SSL etc.)

Search engines

• searchplugins folder

Session storage

• webappsstore.sqlite

Only copy this if you deliberately keep and use many saved sessions.

User styles

• chrome/userChrome.css
• chrome/userContent.css
• chrome/userChrome.js

These optional files change the way Firefox and web pages look.

Riassumendo:

• file bookmarks.html
• file cert8.db
• file cookies.txt
• file formhistory.dat
• file history.dat
• file hostperm.1
• file key3.db
• file mimeTypes.rdf
• file places.sqlite (da release 3.0)
• file prefs.js
• file signons2.txt
• file user.js
• file chrome/userChrome.css
• file chrome/userContent.css
• file chrome/userChrome.js
• folder searchplugins

Upgrading Firefox Portable
To upgrade to a newer version of Firefox Portable, just install a new copy of Firefox Portable right over your old one. All your data will be preserved.

If you're upgrading from Portable Firefox (older name and directories), make a copy if your existing profile folder within the PortableFirefox\Data\profile directory on your portable drive. Then download the new version of Firefox Portable and copy your profile from the old version into the new version within FirefoxPortable\Data\profile.
If you added any plugins or searchplugins, you should copy those directories as well (PortableFirefox\plugins to FirefoxPortable\Data\plugins and PortableFirefox\firefox\searchplugins to FirefoxPortable\App\firefox\searchplugins).
Copying Your Local Firefox Settings
If you're using a local copy of Firefox, you may wish to just copy your local Firefox settings right into Firefox Portable. Your local Firefox profile is usually installed in C:\Documents and Settings\[user]\Application Data\Mozilla\Firefox\Profiles\default.???\ Just copy the contents of that folder (except the cache directories) to the FirefoxPortable\Data\profile directory.
Then, and this is important, delete the file FirefoxPortableSettings.ini within the FirefoxPortable\Data\settings directory, if there is one.
When you start Firefox Portable for the first time, it's recommended that you turn off disk cache, password saving and history if you're using a flash-based portable device.
You can set all of these within the Privacy tab of the Firefox Options window.
Sometimes, certain profiles will cause the launcher to fail or hang. It's best to give it a few minutes to see if it's just checking compatiblity and adjusting the locations of the extensions before giving up on it. If it fails, it is usually due to an incompatible extension.
Here's a list of different things you can do to speed things up:

Disable Cache, History and Form Saving - Cache is disabled by default. In newer releases of Firefox Portable, history and form saving are enabled. You can disable these within the Options window.
Disable Session Restore / Undo Close Tab - Firefox 2.0 introduced a new feature called session restore. It keeps track of all your open windows and tabs and can restore your session if Firefox should crash. While a handy feature, it does have the unfortunate side effect of writing to disk on every page load, which slows down Firefox Portable. There's no option to disable it in the usual Tools - Options windows, but you can disable it manually.

• In Firefox's address bar, type in about:config and then hit enter
• Right-click on any entry and select New - Boolean
• For the name, enter browser.sessionstore.enabled and click OK
• Select false and then click OK

When you restart Firefox, session restore (and undo close tab) will be disabled and you should notice an improvement in browsing speed.
Disable Anti-Phishing - Firefox 2.0 comes bundled with an anti-phishing filter that warns you of fake sites pretending to be things like ebay and bank login pages. As with the ression restore, though, it results in additional writes to the drive. This is especially noticable in the first few minutes of using Firefox Portable as it has to download the anti-phishing database and store it within your profile (a 3mb+ file). You can disable this feature by clicking Tools - Options and then selecting the Security tab. Uncheck the box next to "Tell me if the site I'm visiting is a suspected forgery" and then click OK. The anti-phishing filter is now off. If you'd like to get back the space taken up by the database of forged sites, exit Firefox Portable and then head to the FirefoxPortable\Data\profile directory on your drive. Delete the urlclassifier2.sqlite file.

AutoRun

AutoRun (gee, what an original name) is very simple and basic application to create autorun menu for CD's or DVD's. You can change image, icon, caption, number and function of buttons and their appearance. All changes are done by modifying the ini file and are very easy to understand.

INI settings
Autorun.ini has two sections - [main] and [buttons]. Main
holds information about how application appears, buttons unsurprisingly define
what buttons your autorun has and what they will do. You can see uncommented
example ini contents at the bottom of this page.
All ini commands are in
bold, comments look like this.

Section:
[main]

• Note: You can skip the main section altogether, in that case default values
  are used.
  caption=AutoRundefines the caption of the autorun window. For
  example, it could be:
• caption=Vacation photos, June 2006
• icon=AutoRun.icoIcon that is used for main window and application.
• image=AutoRun.bmpImage on the left. It must be .bmp, but image dimensions
  are not limited.
• imageurl=http://dukelupus.pri.eeURL that opens when user clicks on the
  image. Can also be filename on disc or such.
• url=http://example.comURL in bottom left corner
• flatbuttons=0values are 0/1. Flat buttons look more stylish, but aren't as
  easy to see. Play with that setting.
• ButtonsInColumn=10If the number of buttons is bigger then this value, then
  buttons will be split into as many columns as necessary. Note that "space="
  elements do not count as buttons.
• Top=200Left=300Top and left values determine the location of the AutoRun
  window, starting from the top left corner. If you omit these, the window will be
  placed to the center of the desktop. Do remember that screens have different
  resolutions, so placing it to bottom right corner is not a good idea.
  

Section:
[buttons]

• Buttons will be shown in same order as they appear in ini. You can have as
  little or as many buttons as you want to, window will adjust its size to
  accommodate them. Buttons will also resize themselves if you use very long
  captions. Format is "button caption=function". "Function" can be internet link,
  path to file on CD/DVD (remember to skip disc letter, ie "my
  applications\myapp.exe", not "d:\my applications\myapp.exe"), file to open in
  HDD ("Notepad=notepad.exe") etc. If you link non-executable file (such as .avi,
  .doc or .txt), then it will be opened with the associated program. You can
  create Alt+character shortcuts by prefixing character in name with "&" - for
  example, E&xit - alt+x will be same as clicking on Exit button. If you need
  to have & in button caption, use "&&" - ie, to get "Night &
  Day", use "Night && Day". You cannot have = (equals) character in the
  name. Browse and Exit are pre-defined values and can be used with any buttons.
  For example: &Browse contents of this DVD=Browse
  As of version 1.1, there
  is a special key in the buttons section - "space=number". This allows you to
  have a blank space between the buttons. Number is the height of that space in
  pixels. You can have as many space keys as you want, but do notice that they do
  not count as buttons if you set "ButtonsInColumn" value in main section.
  

These are all just sample buttons:

&Open .ini=AutoRun.ini

Notepad=notepad.exe

c:\=c:\

&Browse=Browse

Home page=http://example.com

space=10

E&xit=Exit

AutoIt

AutoIt is a freeware Windows automation language. It can be used to script most
simple Windows-based tasks (great for PC rollouts or home automation).

tratto dal sito ufficiale.
Utilizzato, tra gli altri, da Jared Breland per il suo Universal Extractor.

AutoIt v3 is a freeware BASIC-like scripting language designed for automating
the Windows GUI and general scripting. It uses a combination of simulated
keystrokes, mouse movement and window/control manipulation in order to automate
tasks in a way not possible or reliable with other languages (e.g. VBScript and
SendKeys). AutoIt is also very small, self-contained and will run on all
versions of Windows out-of-the-box with no annoying "runtimes" required! AutoIt
was initially designed for PC "roll out" situations to reliably automate and
configure thousands of PCs. Over time it has become a powerful language that
supports complex expressions, user functions, loops and everything else that
veteran scripters would expect.

Features:

• Easy to learn BASIC-like syntax
• Simulate keystrokes and mouse movements
• Manipulate windows and processes
• Interact with all standard windows controls
• Scripts can be compiled into standalone executables
• Create Graphical User Interfaces (GUIs) ù
• COM support
• Regular expressions
• Directly call external DLL and Windows API functions
• Scriptable RunAs functions
• Detailed helpfile and large community-based support forums
• Compatible with Windows 95/98/ME/NT4/2000/XP/2003/Vista
• Unicode support
• Digitally signed for peace of mind
• Works with Windows Vista's User Account Control (UAC)
  

AutoIt has been designed to be as small as possible and stand-alone with no
external .dll files or registry entries required making it safe to use on
Servers. Scripts can be compiled into stand-alone executables with
Aut2Exe.Also
supplied is a combined COM and DLL version of AutoIt called
AutoItX that allows
you to add the unique features of AutoIt to your own
favourite scripting or
programming languages!
Best of all, AutoIt
continues to be FREE - but if you
want to support the time, money and effort
spent on the project and web hosting
then you may donate using the link to

Universal Extractor

Universal Extractor is a program do to exactly what it says: extract files from any type of archive, whether it's a simple zip file, an installation program, or even a Windows Installer (.msi) package. (...)
The original motivation behind this project was that I wanted an easy, convenient way to extract files from installation packages, such as Inno Setup or Windows Installer packages, without pulling up a command line every time. In the process I got a little carried away and ended up throwing in support for every kind of archive format I possibly could find.

Hidden Start (hstart)

da ntwind.com

Console applications and batch scripts are regularly run at Windows startup and in schedule. For example, virtual drives are used for frequently accessed directories, meaning that the subst.exe console application has to be run more than once on logon.
The main inconvenience of this is that every application creates a new console window which flickers on the screen. For this reason, I have developed a small startup manager that allows console applications to be started without any windows in the background.

MP3 encoding with LAME (and RazorLAME)

RazorLame è l'ottimo front-end di LAME

Alla data in cui scrivo:
* http://sourceforge.net/projects/lame/
* http://www.dors.de/razorlame/index.php

Il testo che segue è tratto da http://wiki.hydrogenaudio.org/index.php?title=LAME

-----

Best quality: "archiving"
* -b 320.
This is the strongest setting for MP3, with the lowest risk of artifacts. With the exception of a few situations, quality is rarely better than the highest VBR profiles described below. However, 'archiving' music using a lossy format like MP3 is never recommended – no matter how transparent the resulting files might be. The alternative is to use Lossless formats like WavPack, FLAC etc. that allow true archiving bit for bit like on original CD.

High quality: HiFi, home or quiet listening
* -V3 --vbr-new (~175 kbps),
* -V2 --vbr-new (~190 kbps),
* -V1 --vbr-new (~210 kbps) or
* -V0 --vbr-new (~230 kbps) are recommended.
These settings will produce transparent encoding (transparent = most people cannot distinguish the MP3 from the original in an ABX blind test). Audible differences between these presets exist, but are extremely rare.

Portable: background noise and low bitrate requirement, small sizes
* -V6 --vbr-new (~115 kbps),
* -V5 --vbr-new (~130 kbps) or
* -V4 --vbr-new (~160 kbps) are recommended for this use.
-V6 --vbr-new produces an acceptable quality, while -V4--vbr-new should be close to perceptual transparency.

Very low bitrate, small sizes: eg. for voice, radio, mono encoding etc.
For very low bitrates, up to 100kbps, ABR is most often the best solution. Use --abr (e.g. --abr 80).
--preset voice is only available in the command line front-end, and is there for compatibility. It is currently mapped to --abr 56 -mm, so that means that the recommendation would be to encode in mono, and use ABR.


PIU' IN DETTAGLIO...


VBR (variable bitrate) settings
VBR: variable bitrate mode.
Use variable bitrate modes when the goal is to achieve a fixed level of quality using the lowest possible bitrate.
VBR is best used to target a specific quality level, instead of a specific bitrate. The final file size of a VBR encode is less predictable than with ABR, but the quality is usually better.
Usage: -V(number) where number is 0-9, 0 being highest quality, 9 being the lowest.
Example: -V2

ABR (average bitrate) settings
ABR: average bitrate mode.
A compromise between VBR and CBR modes, ABR encoding varies bits around a specified target bitrate. Use ABR when you need to know the final size of the file but still want to allow the encoder some flexibility to decide which passages need more bits. Usage: --preset where (desired averaged bitrate in kbit/s) can be any value between 8 - 320 , like eg. 9, 17, 80, 128, 133, 200 etc. Example: --preset 200

CBR (constant bitrate) settings
CBR: constant bitrate mode.
CBR encoding is not efficient. Whereas VBR and ABR modes can supply more bits to complex music passages and save bits on simpler ones, CBR encodes every frame at the same bitrate. CBR is only recommended for usage in streaming situations where the upper bitrate must be strictly enforced. Usage: -b where (bitrate in kbit/s) must be chosen from the following values: 8, 16, 24, 32, 40, 48, 64, 80, 96, 112, 128, 160, 192, 224, 256, or 320.
Example: -b 192
