MPAA Boss: If The Chinese Censor The Internet, Why Can't The US? (techdirt.com)

2011 Dec 10, 8:31

FTA:

The MPAA is getting pretty desperate, it seems. MPAA boss Chris Dodd was out trying to defend censoring the internet this week by using China as an example of why censorship isn’t a problem. It’s kind of shocking, really.

“When the Chinese told Google that they had to block sites or they couldn’t do [business] in their country, they managed to figure out how to block sites.”

draft-liman-tld-names-06 - Top Level Domain Name Specification

2011 Dec 4, 3:00

“The syntax for allowed Top-Level Domain (TLD) labels in the Domain Name System (DNS) is not clearly applicable to the encoding of Internationalised Domain Names (IDNs) as TLDs. This document provides a concise specification of TLD label syntax based on existing syntax documentation, extended minimally to accommodate IDNs.” Still irritated about arbitrary TLDs.

Swiss government keeps downloading legal after piracy study

“One in three people in Switzerland download unauthorized music, movies and games from the Internet and since last year the government has been wondering what to do about it. … The overall conclusion of the study is that the current copyright law, under which downloading copyrighted material for personal use is permitted, doesn’t have to change.” Wow, that sounds like almost reasonable and understandable copyright law.

JavaScript Array methods in the latest browsers

2011 Dec 3, 6:46

Cool and (relatively) new methods on the JavaScript Array object are here in the most recent versions of your favorite browser! More about them on ECMAScript5, MSDN, the IE blog, or Mozilla's documentation. Here's the list that's got me excited:

some & every
Does your callback function return true for any (some) or all (every) of the array's elements?
filter
Filters out elements for which your callback function returns false (in a new copy of the Array).
map
Each element is replaced with the result of it run through your callback function (in a new copy of the Array).
reduce & reduceRight
Your callback is called on each element in the array in sequence (from start to finish in reduce and from finish to start in reduceRight) with the result of the previous callback call passed to the next. Reduce your array to a single value aggregated in any manner you like via your callback function.
forEach
Simply calls your callback passing in each element of your array in turn. I have vague performance concerns as compared to using a normal for loop.
indexOf & lastIndexOf
Finds the first or last (respectively) element in the array that matches the provided value via strict equality operator and returns the index of that element or -1 if there is no such element. Surprisingly, no custom comparison callback method mechanism is provided.

Bug Spotting: Ctors with default parameters

2011 Dec 1, 4:59

The following code compiled just fine but did not at all act in the manner I expected:

BOOL CheckForThing(__in CObj *pObj, __in IFigMgr* pFigMgr, __in_opt LPCWSTR url)
{
BOOL fCheck = FALSE;
if (SubCheck(pObj))
{
...
I’m calling SubCheck which looks like:
bool SubCheck(const CObj& obj);

Did you spot the bug? As you can see I should be passing in *pObj not pObj since the method takes a const CObj& not a CObj*. But then why does it compile?

It works because CObj has a constructor with all but one param with default values and CObj is derived from IUnknown:

CObj(__in_opt IUnknown * pUnkOuter, __in_opt LPCWSTR pszUrl = NULL);
Accordingly C++ uses this constructor as an implicit conversion operator. So instead of passing in my CObj, I end up creating a new CObj on the stack passing in the CObj I wanted as the outer object which has a number of issues.

The lesson is unless you really want this behavior, don't make constructors with all but 1 or 0 default parameters. If you need to do that consider using the 'explicit' keyword on the constructor.

More info about forcing single argument constructors to be explicit is available on stack overflow.
