Patent Office tries “Stack Overflow for patents” to find prior art | Ars Technica

2012 Sep 20, 2:27

Welcome news. Glad to hear they’re looking for improvements.

… the USPTO has also worked with Stack Exchange, … to create a new site called Ask Patents. … Examiners or others looking for prior art can post questions about a specific application, and members of the general public can respond with evidence that an applicant was not the first to invent the subject matter of the application.

WHATWG Weekly: http+aes URL scheme, control Referer, …

2012 Mar 7, 8:08

Seems generally bad to embed sensitive info in the URI (the http+aes URI scheme’s decryption key) similar to the now deprecated password field.

Use case is covered here: http://lists.w3.org/Archives/Public/ietf-http-wg/2012JanMar/0811.html.  Also discussion including someone mentioning the issue above.

Client Side Cross Domain Data YQL Hack

2012 Feb 27, 2:28

One of the more limiting issues of writing client side script in the browser is the same origin limitations of XMLHttpRequest. The latest version of all browsers support a subset of CORS to allow servers to opt-in particular resources for cross-domain access. Since IE8 there's XDomainRequest and in all other browsers (including IE10) there's XHR L2's cross-origin request features. But the vast majority of resources out on the web do not opt-in using CORS headers and so client side only web apps like a podcast player or a feed reader aren't doable.

One hack-y way around this I've found is to use YQL as a CORS proxy. YQL applies the CORS header to all its responses and among its features it allows a caller to request an arbitrary XML, HTML, or JSON resource. So my network helper script first attempts to access a URI directly using XDomainRequest if that exists and XMLHttpRequest otherwise. If that fails it then tries to use XDR or XHR to access the URI via YQL. I wrap my URIs in the following manner, where type is either "html", "xml", or "json":

        yqlRequest = function(uri, method, type, onComplete, onError) {
var yqlUri = "http://query.yahooapis.com/v1/public/yql?q=" +
encodeURIComponent("SELECT * FROM " + type + ' where url="' + encodeURIComponent(uri) + '"');

if (type == "html") {
yqlUri += encodeURIComponent(" and xpath='/*'");
}
else if (type == "json") {
yqlUri += "&callback=&format=json";
}
...

This also means I can get JSON data itself without having to go through JSONP.

Copyright King: Why the "I Have a Dream" Speech Still Isn't Free (vice.com)

2012 Jan 17, 9:37

There’s weird stuff you’d think is public domain but isn’t including Martin Luther King Jr.‘s “I Have a Dream” speech. FTA: ”If you want to watch the whole thing, legally, you’ll need to get the $20 DVD.

That’s because the King estate, and, as of 2009, the British music publishing conglomerate EMI Publishing, owns the copyright of the speech and its recorded performance.”

Indicating Character Encoding and Language for HTTP Header Field Parameters

2011 Nov 24, 7:45

From the document: ‘Appendix B. Implementation Report: The encoding defined in this document currently is used for two different HTTP header fields: “Content-Disposition”, defined in [RFC6266], and “Link”, defined in [RFC5988]. As the encoding is a profile/clarification of the one defined in [RFC2231] in 1997, many user agents already supported it for use in “Content-Disposition” when [RFC5987] got published.

Since the publication of [RFC5987], two more popular desktop user agents have added support for this encoding; see http://purl.org/
   NET/http/content-disposition-tests#encoding-2231-char for details. At this time, only one major desktop user agent (Safari) does not support it.

Note that the implementation in Internet Explorer 9 does not support the ISO-8859-1 encoding; this document revision acknowledges that UTF-8 is sufficient for expressing all code points, and removes the requirement to support ISO-8859-1.’

Yay for UTF-8!

Telex

2011 Jul 18, 2:38Neat idea: "When the user wants to visit a blacklisted site, the client establishes an encrypted HTTPS connection to a non-blacklisted web server outside the censor’s network, which could be a normal site that the user regularly visits... The client secretly marks the connection as a Telex request by inserting a cryptographic tag into the headers. We construct this tag using a mechanism called public-key steganography... As the connection travels over the Internet en route to the non-blacklisted site, it passes through routers at various ISPs in the core of the network. We envision that some of these ISPs would deploy equipment we call Telex stations."PermalinkCommentsinternet security tools censorship technical

For instance to pick 'xn--' for the IDN prefix from a set of prefixes, they decided on a hash, a set of stocks and a time in the future to generate the hash from the stock values. The resulting value is random and anyone can check the work to verify that it was chosen randomly.

Google and Outlook Calendar Sync'ing

2010 Jul 8, 9:00
I previously described my desire to hook my Outlook calendar up to my Google calendar. I just found out that I can do this and the reverse as both support publishing calendars to the Internet. The following are how I set this up under Outlook 2010 and Google Calendar:

In Outlook, I go to the calendar view, right click on my calendar and select "Share Publish to Office.com". At this point I can change the permissions to allow anonymous Internet access, and under Detail change between 'Full details' (full calendar), 'Limited details' (subject lines & availability only), 'Availability only'. Availability only is almost just what I want -- I'd also like to include location but availability only is good enough. After hitting OK here I get a 'Do you want to send an invitation...' dialog box. I hit 'Yes' and I can copy the webcals:// URL out of the email window that opens up. Next, to add it to my Google calendar, I open http://www.google.com/calendar/, and under 'Other calendars', I select 'Add Add by URL', paste in that webcals:// URL but change the 'webcals' at the start to 'https'.

In Google Calendar, I can click on my calendar name under 'My calendars', select 'Calendar settings', and on the new page, look under 'Calendar Address', click the ICAL icon, and copy the URL in the new dialog. Now back in Outlook I go to the Calendar view, right click on 'My Calendars', and select 'Add Calendar From Internet...'. In the new dialog that pops up I paste in the URL from Google Calendar.

In this fashion I can share public calendar data between my personal and work calendars.
