Are There Any Pros to Use HTML 5 Doctype `<!DOCTYPE html>` Without Using HTML 5 Tags?

由 旧时模样 提交于 2019-12-10 19:56:40
问题 Are there any pros to use the HTML 5 doctype <!DOCTYPE html> , even if I am not using any new HTML 5 tags? Are there any benefits to replacing the XHTML doctype with the HTML 5 doctype, even if I am not using any new HTML 5 tags? Can the HTML 5 doctype create problems in terms of functionality if I am using anything XML related with my site, or using HTML 5 for web development with any A-Grade browser? Is it supported in all desktop and mobile browsers? Or, for right now, is it good to stick

Cross Platform way to get the time of day?

由 断了今生、忘了曾经 提交于 2019-12-10 18:29:40
问题 Is there a simple way to get time time of day (17:30, 01:20...etc) that would work on iOS, OSX, Linux and Windows? If not is there a Windows way and a posix way or something? Thanks 回答1: You can retrieve the time with time_t now = time(NULL); or time(&now); You then usually convert to local time with struct tm *tm_now = localtime(&now); . A struct tm contains fields for the year, month, day, day of week, hour, minute, and second. If you want to produce printable output, strftime supports that

Is there a platform independent way (Java?) to read an audio CD's TOC?

由 て烟熏妆下的殇ゞ 提交于 2019-12-10 18:28:16
问题 I would like to avoid using native libaries if at all possible. Surely there is a better way to solve this issue for Linux, Windows and Mac OS X. 回答1: Sorry, you're out of luck. You'll need JNI, and it'll be obnoxiously different for different platforms. The base java libraries cover tasks and hardware that are pretty much universal. CD drives weren't and aren't considered so. 回答2: You can use the Java Sound API. I believe this is part of java 5. This may allow you to do what you want to do.

superscalar and VLIW

由 ε祈祈猫儿з 提交于 2019-12-10 17:22:56
问题 I want to ask some questions related to ILP. A superscalar processor is sort of a mixture of the scalar and vector processor. So can I say that architectures of vector processor follows super-scalar ? Processing multiple instructions concurrently does not make an architecture superscalar, since pipelined, multiprocessor or multi-core architectures also achieve that. What does this means? I have read ' A superscalar CPU architecture implements a form of parallelism called instruction level

How important is platform independence?

由 懵懂的女人 提交于 2019-12-10 16:54:32
问题 A lot of software frameworks, languages, platforms claim platform independence and boast it as a selling feature. However, I have failed to understand how could this such an important feature. For example, Java is said to be platform independent - but why should I care when I know that my webapp is going to run on only one platform? Is the overhead of making an application platform independent really worthwhile? 回答1: If you know your app is going to run on only one platform you shouldn't care

Can SQL Server bcp in a file with Unix line endings?

由 余生长醉 提交于 2019-12-10 16:31:10
问题 I'm trying to use the SQL Server bcp utility to import a text file from a samba share. bcp is choking on the Unix line endings. I'm sure I could add an intermediate step, either on Unix or Windows, to change the line endings to Windows-style. But I would prefer to import the files from Unix without modification. Anybody know if there's a way to tell SQL Server bcp to look for Unix line endings? 回答1: You have to use a format file with bcp and specify the terminator as \n. The interactive

How should I account for subprocess.Popen() overhead when timing in python?

问题 more-intelligent-members-of-the-coding-community-than-I! I have a python question for you all... :) I am trying to optimize a python script that is (among other things) returning the wall-clock time a subprocess took execute and terminate. I think I'm close with something like this. startTime = time.time() process = subprocess.Popen(['process', 'to', 'test']) process.wait() endTime = time.time() wallTime = endTime - startTime However, I am concerned that the overhead in subprocess.Popen() is

Vici CoolStorage Portability: Monotouch, MonoDroid and Windows Phone

由 拥有回忆 提交于 2019-12-10 14:56:57
问题 Is cross-platformness a good reason to use Vici CoolStorage? Ideally you'd want to write data model once and use it in MonoTouch, MonoDroid and Windows Phone versions of the same app. In that case is Vici CS the best bet? 回答1: I don't have much experience with other ORMs, so I can't compare CoolStorage with other options. I can tell you, though, that the code you write for your CoolStorage data layer will be 100% re-usable over the 3 platforms. Simply write a separate data layer library and

How can I set up a git repository on windows, and then push to/pull from it on Mac OSX

由 走远了吗. 提交于 2019-12-10 14:42:54
问题 I'm trying to set up a Windows-based web server, but do the development work on Mac OSX. I installed freeSSHd and msysGit on the Windows server, and set up a repository where I want it. I also have git on my Mac and set up a repo there too. When I try to clone, pull from, or push to the windows repo via SSH, it gives me an error, "fatal: protocol error: bad line length character" It doesn't matter what I set the remote to in my client (Mac OSX) machine - I can point it to a folder that doesn

Is numpy.save cross platform?

由 有些话、适合烂在心里 提交于 2019-12-10 13:57:54
问题 Suppose I save a numpy array to a file, "arr.npy", using numpy.save() and that I do this using a particular python version, numpy version, and OS. Can I load, using numpy.load(), arr.npy on a different OS using a different version of python or numpy? Are there any restrictions, such as backwards compatibility? 回答1: Yes. The .npy format is documented here: https://github.com/numpy/numpy/blob/master/doc/neps/npy-format.rst Note this comment in the source code (emphasis mine): The .npy format is
