萝らか妹 提交于 2019-11-27 03:31:22
Can I convert iso date to milliseconds? for example I want to convert this iso 2012-02-10T13:19:11+0000 to milliseconds. Because I want to compare current date from the created date. And created date is an iso date. Try this var date = new Date("11/21/1987 16:00:00"); // some mock date var milliseconds = date.getTime(); // This will return you the number of milliseconds // elapsed from January 1, 1970 // if your date is less than that date, the value will be negative EDIT You've provided an ISO date. It is also accepted by the constructor of the Date object var myDate = new Date("2012-02-10T13

What is the simplest standard conform way to produce a Segfault in C?

I think the question says it all. An example covering most standards from C89 to C11 would be helpful. I though of this one, but I guess it is just undefined behaviour: #include <stdio.h> int main( int argc, char* argv[] ) { const char *s = NULL; printf( "%c\n", s[0] ); return 0; } EDIT: As some votes requested clarification: I wanted to have a program with an usual programming error (the simplest I could think of was an segfault), that is guaranteed (by standard) to abort. This is a bit different to the minimal segfault question, which don't care about this insurance. Shafik Yaghmour A

Why is getcwd() not ISO C++ compliant?

↘锁芯ラ 提交于 2019-11-27 02:16:25
问题 This MSDN article states that getcwd() has been deprecated and that the ISO C++ compatible _getcwd should be used instead, which raises the question: what makes getcwd() not ISO-compliant? 回答1: Functions not specified in the standard are supposed to be prefixed by an underscore as an indication that they're vendor-specific extensions or adhere to a non-ISO standard. Thus the "compliance" here was for Microsoft to add an underscore to the name of this specific function since it's not part of

Android camera preview is dark

喜欢而已 提交于 2019-11-27 02:02:06
问题 I am trying to create a custom camera app. I followed the Android Developer example from here with minor tweaks. However, my camera preview turns out to be rather dark. On the other hand, the stock camera gives a much brighter preview. I have tried several settings to make it work better but it seems none of them are having any impact. Relevant code is posted here. CameraActivity (Main) protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R

Bitwise shift operators on signed types

↘锁芯ラ 提交于 2019-11-26 21:38:04
问题 I am trying to understand the behavior of bitwise operators on signed and unsigned types. As per the ISO/IEC document, following are my understandings. Left shift Operator The result of E1 << E2 , is E1 left-shifted E2 bit positions The vacated bits on the account of left shift will be filled by zeros. E1 as signed non-negative: E1 << E2 will result to E1 multiplied by 2 power of E2, if the value is representable by the result type. Q1: What about signed negatives? Q2: I am not able to

Why an unnamed namespace is a “superior” alternative to static? [duplicate]

陌路散爱 提交于 2019-11-26 21:21:33
This question already has an answer here: Superiority of unnamed namespace over static? 3 answers The section $7.3.1.1/2 from the C++ Standard reads: The use of the static keyword is deprecated when declaring objects in a namespace scope; the unnamed-namespace provides a superior alternative. I don't understand why an unnamed namespace is considered a superior alternative? What is the rationale? I've known for a long time as to what the standard says, but I've never seriously thought about it, even when I was replying to this question: Superiority of unnamed namespace over static? Is it

Converting country codes in .NET

烈酒焚心 提交于 2019-11-26 19:34:26
问题 In .NET is there any way to convert from three letter country codes (defined in ISO 3166-1 alpha-3) to two letter language codes (defined in ISO 3166-1 alpha-2) eg. convert BEL to BE? Have looked at the RegionInfo class in System.Globalization but the constructor does not seem to support the three letter codes. 回答1: The RegionInfo class does know the three-letter code (in the ThreeLetterISORegionName property), but I don’t think there is a way to get RegionInfo based on this code, you would

Can we apply content not explicitly cited from the normative references to the C++ standard?

好久不见. 提交于 2019-11-26 16:24:15
问题 In the C++11 standard( closest draft is N3337 ) section 1.2 Normative references says: The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. but there are no guidelines on how to apply the references. The easy cases are when the C++11 explicitly refers back to a reference, for example in section 3.9
