FTA: “Nick Bilton put the FAA’s claims regarding Kindles and airline avionics to the test. The result? They emit less EM interference than planes are required by law to withstand.” Much less, apparently.

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.”
“How pervasive is it? There are about 489,000 YouTube videos that say “no copyright intended” or some variation, and about 664,000 videos have a “copyright disclaimer” citing the fair use provision in Section 107 of the Copyright Act”
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.
“TechCrunch and others are reporting that a program called “Carrier IQ” that comes pre-installed on Sprint phones has some pretty amazing spyware capabilities, right down to keylogging everything you do on the phone.”

Rosenfeld debuted the helmet at this year’s Halloween” (via The Big Head, A Giant Videoconferencing Helmet by Dan Rosenfeld)
