Did you know there’s an ISO for sex?

Turns out that there is an ISO standard for sex. Man is 1 and woman is 2. But why man precedes woman? The standard explicitly states that no significance is to be placed on the fact that male is encoded as 1 and female as 2. The encoding merely reflects existing practice in the countries that initiated this standard.

More information at ISO.

International standard ISO 5218 defines a representation of human sexes through a language-neutral single-digit code. It can be used in information systems such as database applications. (Source: Wikipedia)

The four codes specified in ISO 5218 are:

  • 0 = not known,
  • 1 = male,
  • 2 = female,
  • 9 = not applicable.

Did you know the ‘Referer’ in HTTP is spelt wrongly?

Well it is. Here is what’s written in the RFC 2616 – Hypertext Transfer Protocol — HTTP/1.1:

The Referer[sic] request-header field allows the client to specify, for the server’s benefit, the address (URI) of the resource from which the Request-URI was obtained (the “referrer”, although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance. The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard.

[code lang=”bash”]Referer = “Referer” “:” ( absoluteURI | relativeURI )[/code]


[code lang=”bash”]Referer: http://www.w3.org/hypertext/DataSources/Overview.html[/code]

If the field value is a relative URI, it SHOULD be interpreted relative to the Request-URI. The URI MUST NOT include a fragment. See section 15.1.3 for security considerations.

The referrer, or HTTP referrer — also known by the common misspelling referer that occurs as an HTTP header — identifies, from the point of view of an internet webpage or resource, the address of the webpage (commonly the URL, the more generic URI or the i18n updated IRI) of the resource which links to it. By checking the referrer, the new page can see where the request came from. Referrer logging is used to allow websites and web servers to identify where people are visiting them from, for promotional or security purposes. Referrer is a popular tool to combat cross-site request forgery, but such security mechanisms do not work when the referrer is disabled. Referrer is widely used for statistical purposes.

Apple: iPhone ‘really fast’, UK regulators thinks otherwise

Responding to 17 people’s complaints that the Apple advertisement misled them on the speed of the Apple iPhone, Advertising Standards Authority (ASA) determines that the “advertisement must not appear again in the same form”.

Apple made to drop iPhone advert

The Advertising Standards Authority (ASA) upheld complaints by 17 people who said the TV advert had misled them as to its speed.

Apple UK said it was comparing the 3G model with its 2G predecessor and its claims were “relative not absolute”.

The advert repeatedly stated that the phone was “really fast” and showed news pages and the Google maps service taking just fractions of a second to appear.

Text on the screen said: “Network performance will vary by location.”

After upholding the viewers’ complaints, the ASA said the advert must not appear again in the same form.

It said the advert was likely to lead viewers to believe that the device actually operated at or near to the speeds shown in the advert.

The watchdog concluded: “Because we understood that it did not, we concluded that the ad was likely to mislead.” (Source: BBC)

It’s not the first time advertisements mislead. Most do anyway. Just like blog titles. Meh.
