Windows Live Hotmail and Hotmail integration with Windows Live SkyDrive: 25MB (and 100MB/file with a free personal storage of 25 GB  SkyDrive).
On June 20, 2011, Microsoft overhauled the user interface for Windows Live SkyDrive, built using HTML5 technologies. Microsoft also doubled the file size limit from 50MB to 100MB per file, as well as adding new features such as caching and hardware acceleration, support for HTML5 videos, Quick views, cleaner arrangement of photos, infinite scrolling. This update also brings together the different entry points for SkyDrive, such as Windows Live Photos and Windows Live Office, into one single interface. Files and folders shared with a user, including those in Windows Live Groups are also accessible in the new interface. On December 3, 2011, Microsoft released a SkyDrive for iPhone/iPod Touch app, and a SkyDrive for Windows Phone app, which are available in the App Store and Windows Phone Marketplace respectively.
http://windowsteamblog.com/windows_live/b/windowslive/archive/2011/06/20/introducing-skydrive-for-the-modern-web-built-using-html5.aspx
Entire directories can be downloaded as a single .zip file with SkyDrive.
Hotmail integration with Windows Live SkyDrive: SkyDrive integrates with Windows Live Hotmail which allow users to:

1.     Directly upload Office documents and photos within Hotmail, store them on Windows Live SkyDrive, and share them with other users
2.     Directly save Office documents within Hotmail to Windows Live SkyDrive, and view or edit these documents directly within the web browser
3.     Allow Hotmail users to edit Office documents within the web browser using Office Web Apps, and reply directly back to the sender with the edits made.

File delivery is not a file sharing service.
Webmail providers and webmail programs are not equivalent ;)

-----email attachment?
An email attachment is a computer file sent along with an email message. 
Email standards such as MIME don't specify any file size limits, but in practice email users will find that they can't send very large files.
 Over the Internet a message will often pass through several mail transfer agents to reach the recipient. Each of these has to store the message before forwarding it on, and may therefore need to impose size limits.
Email users can be puzzled by these limits because the MIME encoding adds up to 30% overhead– so that a 20MB document on disk exceeds a 25MB file attachment limit.

Setting Message Size Limits in Exchange 2010 and Exchange 2007:
http://exchangepedia.com/2007/09/exchange-server-2007-setting-message-size-limits.html

--History:
Originally Internet SMTP email was 7-bit ASCII text only.
You can put a latex source in your email directly because it's a 7-bit ASCII text
Attaching files was done by manually encoding 8-bit files using uuencode, BinHex... and pasting the resulting text into the body of the message. It was not easy but funny to undersant something in computer science ;)
The MIME standard introduced by RFC2045 in 1996 provided a framework to encapsulate a message and all its attachments in a single multipart message, and standardised on base64 encoding to convert binary into 7-bit ASCII.
Modern mail servers running Extended SMTP have the option of advertising full 8-bit support via the 8BITMIME extension.

The first email attachment was sent on 1992, 20 yrs ago!

---latex rendering
You can put a latex source in your email directly because it's a 7-bit ASCII text.
With Gmail, you can add a LaTeX rendering: http://alexeev.org/gmailtex.html
GmailTeX works in all modern browsers: Mozilla Firefox (version 3.6 and later), Google Chrome, Opera, Safari (version 5), and Microsoft Internet Explorer (version 9).
GmailTeX uses MathJax as its TeX typesetting engine.
For LaTeX in Gmail Chat, you can use the GmailChatTeX userscript. To view LateX on web pages where a web designer did not provide a server-side way of doing so (such as arXiv.org, front.math.ucdavis.edu), you can use display-latex2 userscript.

For the other webmail, there is this Greasemonkey script that detects and renders inline LaTeX as MathML. It works pretty well at what it does.

------some free web-based webmail groupwares.
Horde : its Internet Messaging Program or IMP is an open source PHP-based webmail client for IMAP. IMP is a component of the Horde project. It is included with cPanel and Plesk installations as a webmail client. It often integrates email, calendar, address book, notes, tasks, filters and a newsreader with cPanel.
SquirrelMail is an Open Source project that provides both a web-based email application and an IMAP proxy server.
Roundcube is a web-based IMAP email client written in the PHP programming language. Roundcube's most prominent feature is the pervasive use of Ajax technology to present a more fluid and responsive user interface than that of traditional webmail clients.
Zimbra Collaboration Suite (ZCS) .

My personal experience: SquirrelMail is robust, Roundcube is clean, Horde Mail is professional.

-------some webmail (and webmail provider):
AOL Mail is a free web-based email (webmail) service provided by AOL. The service is sometimes referred to as AIM Mail where AIM stands for AOL Instant Messenger which is AOL's instant messaging service. It uses Dojo Toolkit, an open source modular JavaScript library (or more specifically JavaScript toolkit) designed to ease the rapid development of cross-platform, JavaScript/Ajax-based applications and web sites.
Windows Live Hotmail, or MS hotmail: Hotmail features unlimited storage, Ajax, and integration with Microsoft's instant messaging (Windows Live Messenger), calendar (Hotmail Calendar), file hosting service (SkyDrive) and contacts platform.... In October 2011, Microsoft unveiled a "re-invented Hotmail", and added lots of new features such as Instant Actions, scheduled Sweep, Categories and more, and this update began fully rolling out on November 9, 2011.This update also made SSL enabled by default on all accounts.
Yahoo! Mail was the second largest web-based email service with 310 million users as of dec 2011, and the most popular webmail service in the United States.The  Yahoo Mail (before 2011) was based on Ajax scripting acquired from Oddpost, (JavaScript and XML), along with new philosophical approaches to email, including the Oddpost design philosophy. The new version of Yahoo! Mail, codenamed "Minty", was first announced on 16 September 2010 on the Yahoo! Mail Blog. It included a new interface, enhanced performance, improved Facebook and Twitter integration, the ability to watch YouTube videos straight from your email, improved search, and more. Email attachment limit: 25 MB (up to 100 MB via the built-in 'Attach Large Files' app).

Gmail. Gmail is noted by web developers for its pioneering use of Ajax. The Gmail service currently provides 7.8 GB of free storage per account. Users can rent additional storage (shared between Picasa Web Albums, Google Docs and Gmail) from 20 GB (US$5/year) to 16 TB (US$4096/year).
On August 31, 2011, it was announced on the Official Gmail Blog that Offline Google Mail was launched as a Chrome web app at the Google Chrome Web Store. This HTML5-powered app is based on the Gmail web app on tablets. On April 11, 2011 Google engineer Sundar Pichai revealed that Google employees had been testing the app together with offline versions of Google Docs and Google Calendar for months.
The Gmail interface differs from other Webmail systems with its focus on search and its "conversation view" of email, grouping several replies onto a single page.  As a result of complaints from some users, Google made conversation view optional starting September 29, 2010.

How to generate a list of bibliographic references for Wikipedia?

There are two approaches to generate a list of bibliographic references for Wikipedia:
1) Zotero: http://www.zotero.org/support/kb/zotero_and_wikipedia
2) http://reftag.appspot.com/ (from Google Books).


How to:

A) with Zotero or reftag, save direclty to the wikipedia format.


B) and after go to wikipedia 
B-1) for book(s), use "template:Cite book" 
http://en.wikipedia.org/wiki/Template:Cite_book
B-1) use citation templates
http://en.wikipedia.org/wiki/Citation_templates

C) your biblio is OK and with zotero or other similar web services, users can save this list (COinS are generated by wikipedia in your page).

SEE this ex-ample:

http://fr.wikipedia.org/wiki/Publications_Mission_Ressources_et_Comp%C3%A9tences_Technologiques

http://fr.wikipedia.org/wiki/Cat%C3%A9gorie:Mod%C3%A8le_pour_bibliographie


-----Rem:
Zotero's Quick Copy feature makes it trivial to export Zotero items to Wikipedia. The configuration panel for Quick Copy is found by clicking the gear icon in the Zotero toolbar, choosing Preferences, then selecting the Export tab. If Wikipedia Citation Templates is set as the default output format, you can copy properly formatted templates for selected items to the clipboard by using the keyboard shortcut set in the Shortcut Keys preference pane or by dragging and dropping items directly into a text area on Wikipedia.

google take out: save your Google Profile, stream, +1s, Contacts and circles, Picasa web album, and Voice (and the deprecated buzz service)

Google has launched a new web service entitled Takeout. Take-out is food purchased at a restaurant for the purpose of being eaten elsewhere. This is the same! 
Facebook is not the only online place you store valuable data. You also have important information stored in your Google Profile, stream, +1s, Contacts and circles, Picasa web album, and Voice (and the deprecated buzz service). If want a backup of these online information, take-out is a perfect "one-click service". With Google Takeout, voice mail messages are exported as MP3s, text messages as microformatted HTML, and forwarding phone numbers as a vCard. 
The data is compressed into a ZIP archive and made available for download.

List of popular file formats and filter encoding for Map mashups and Geographic information systems; converters of waypoints, tracks, routes

Some popular file formats:

Latitude and longitude are expressed in decimal degrees using the WGS 84 datum. Elevation is recorded in meters. Dates and times are not local time, but instead are Coordinated Universal Time (UTC) using ISO 8601 format.
Find your references in any number of formats:
http://spatialreference.org/
http://spatialreference.org/ref/ it's a listing of spatial references (EPSG) and an interface to search for spatial references. EPSG codes are numeric codes associated with coordinate system definitions. For instance, EPSG:4326 is geographic WGS84.
Projections (a mathematical transformation of the surface of a sphere (3D) onto a 2D plane) are ordered roughly chronologically by type: http://www.radicalcartography.net/?projectionref
Spherical Mercator (http://en.wikipedia.org/wiki/Mercator_projection) is used to describe the PROJECTION used by many commercial API providers.

-geoJSON
The GeoJSON format specification was finalized in June 2008.
http://en.wikipedia.org/wiki/GeoJSON
http://geojson.org/geojson-spec.html
GeoJSON is a geospatial data interchange format based on JavaScript Object Notation (JSON).
 In fact, every GeoJSON data structure is also a JSON object, and thus JSON tools can also be used for processing GeoJSON data.
http://www.geowebguru.com/articles/97-technical-overview-geojson
JavaScript Object Notation (JSON), and the terms object, name, value, array, and number, are defined in IETF RTC 4627, at http://www.ietf.org/rfc/rfc4627.txt
http://en.wikipedia.org/wiki/JSON
JSON is simply a mixture of JavaScript object and array literals without variable definitions.
JSON, is a text-based open standard designed for human-readable data interchange. It is derived from the JavaScript scripting language for representing simple data structures and associative arrays, called objects. Despite its relationship to JavaScript, it is language-independent, with parsers available for most languages.The JSON format is used primarily to transmit data between a server and web application (serving as an alternative to XML;  it is generally more compact than XML).

Spatial data format types supported in GeoJSON include points, polygons, multipolygons, features, geometry collections, and bounding boxes, which are stored along with feature information and attributes. The geometries and their properties will have a parent object.
GeoJSON also allows specifying a geographic coordinate system, using the OGC crs (coordinate reference system) property (preferred) or with an EPSG code. If a crs is not defined, GeoJSON will use the WGS84 geoid by default.
GeoJSON is supported by numerous mapping and GIS software packages. Google maps, google maps api...use JSON


-geoRSS
http://en.wikipedia.org/wiki/GeoRSS
http://www.georss.org/Main_Page

As RSS and Atom become more prevalent as a way to publish and share information, it becomes increasingly important that location is described in an interoperable manner so that applications can request, aggregate, share and map geographically tagged feeds.

There are currently two encodings of GeoRSS, Simple and GML (GeoRSS Geography Markup Language (GML)):
GeoRSS-Simple is meant as a very lightweight format that developers and users can quickly add to their existing feeds. It supports basic geometries (point, line, box, polygon) and covers the typical use cases when encoding locations.
GeoRSS GML is a formal GML Application Profile, and supports a greater range of features, notably coordinate reference systems other than WGS-84 latitude/longitude.
Both formats are designed for use with Atom 1.0, RSS 2.0 and RSS 1.0.

-XML: SVG - Scalable Vector Graphics is an XML format. I think that this file format must be in this GIS list because may map servers use this format and all modern browsers use this format.

-XML-based interchange format: GPX or GPS eXchange Format
GPX – XML-based interchange format
http://en.wikipedia.org/wiki/GPS_eXchange_Format

It describes waypoints, tracks, and routes. 

A collection of points (with no sequential relationship)  is deemed a collection of individual waypoints.
An ordered collection of points may be expressed as a track or a route.  Tracks are a record of where a person has been (with timestamp (because someone is recording where and when they were there)) and routes are suggestions about where you might go in the future...
View the official site: http://www.topografix.com/gpx.asp

-XML-based interchange format: KML
KML – Keyhole Markup Language, XML-based
http://en.wikipedia.org/wiki/Keyhole_Markup_Language
The KML file specifies a set of features (place marks, altitude, images, 3D models, polygons, textual descriptions, camera view...).  Each place always has a longitude and a latitude.
KML files are distributed in KMZ files, which are zipped files with a .kmz extension.
http://schemas.opengis.net/kml/2.2.0/

Developer's Guide: http://code.google.com/apis/kml/documentation/topicsinkml.html
http://kml-samples.googlecode.com/svn/trunk/interactive/index.html


Google Maps supports the following KML elements (that is, KML queries in the Search box and GGeoXml objects in the Maps API):

• Placemarks
• Icons
• Folders
• Descriptive HTML
• Entity replacement via and
• KMZ (compressed KML, including attached images)
• Polylines and polygons
• Styles for polylines and polygons, including color, fill, and opacity
• Network links to import data dynamically
• Ground overlays and screen overlays

This list does not apply to Google Earth's export to Google Maps, My Maps import, or My Maps export to Google Earth.

Maximum uncompressed KML file size=10MB.
Maximum number of Network Links=10.

convert GIS data to KML files
You can import GIS Data and file (ESRI Shape, MapInfo .tab data; GeoTIFF, or other raster dataset) into Google Earth Pro so that it can be used as part of your Google Earth visualizations: http://earth.google.com/outreach/tutorial_importgis.html. If you have Google Earth Pro, you can import many kinds of GIS data directly using the methods described in this tutorial. If you are using the free version of Google Earth, there are other tools for converting GIS data to KML.


ESRI ArcGIS and MapInfo, have tools to export GIS data into KML format (for use in Google Earth).

ogr2gui (http://sourceforge.net/projects/ogr2gui/): a free utility that converts many formats, including shapefiles to KML.
shp2kml (http://www.zonums.com/shp2kml.html): a free utility that converts shapefiles to KML.
MapWindow GIS has Shape2Earth (http://shape2earth.com/default.aspx), a tool for converting GIS data to KML.
ESRI ArcGIS contains tools in the ArcToolbox (Conversion Tools > To KML) for converting vector and raster GIS data to KML.
Arc2Earth (http://www.arc2earth.com/) is an extension for ArcGIS that converts GIS data to KML. The Arc2Earth Community Edition (http://www.arc2earth.com/communityedition/) is a free tool that has lower limits than the full version.
MapInfo Professional has a MapInfo Professional Google Earth Link Utility: http://mapinfo-to-google-earth-tm-export-utilit.software.informer.com/

OpenDocument Spreadsheet (.ods) - Up to 1 MB
Keyhole Markup Language (.kml) - Up to 100 MB
Data already in a Google Spreadsheet
If you have datasets in Excel or Open Office Spreadsheets that are larger than 1MB, save them as CSV files to take advantage of the larger 100MB limit!

Manage your Data with Open Data Kit Aggregate:
http://earth.google.com/outreach/tutorial_odk_aggregate.html
Open Data Kit (ODK) is a suite of tools that allows data collection using mobile devices and data submission to an online server, even without an Internet connection or mobile carrier service at the time of data collection. Once you've collected data in the field with ODK Collect, you can upload and manage your data using ODK Aggregate. ODK Aggregate is the intermediary server storage platform that accepts the data and can send it on to external applications, if desired. ODK Aggregate also allows you to download your datasets in aggregated formats, such as one .csv file. ODK Aggregate allows you to use Google's AppEngine hosting platform (see many post of this blog) for managing your collected data online.
