tags

问题 There are alot of methods to get latest tags when you have local git repo. But i want to get list of latest tags on remote repo. I know about "git ls-remote", and everything is fine when you use tags like x.y.z (where x,y,z are numbers). But when tags looks like "test-x.y.z" and "dev-x.y.z" i noticed that large amount of "test" tags will pull out any new "dev" tags, which is not correct. So, how would you like solve this? 回答1: With Git 2.18 (Q2 2018), git ls-remote learned an option to allow

问题 This is the same question as: Explicit Element Closing Tags with System.Xml.Linq Namespace but I use Net 4.0 and the answers do not work anymore.

问题 I ordered a bunch of NFC tags from a Chinese supplier (I know, red flags) with the promise that they will serialize my tags as instructed so it will work w/ our software and avoid serial duplicates. (Our software uses the tags' serial numbers, not the content.) Now the thousands of NFC tags arrived and it seems they have disregarded the proper serialization, and worst, half of the darn thing are duplicates (completely unusuable for our purpose!) So now I'm in a hole :( So is there a software

问题 Most examples I've seen have scripts in a html page being enclosed by <!-- ... --> I've tried writing it without the comment tags and there doesn't seem to be any difference. Why is the comment tag used and what function does it serve? 回答1: It's not really necessary any more. This has only ever served as a backwards-compatibility hack of sorts - when scripts first started being inserted into static HTML pages, most browsers couldn't support them. Without the comments, they would ignore the

If you know any other information, please give me your advice on that. 回答1: A phone does not necessarily have a fixed anti-collision identifier ("NFC Tag ID", as you call it).

问题 I'm a complete and utter noob, so be gentle! I'm using git gui, and never touching the command line interface. I'm a noob, and some of the people i'm working with are even noob-ey-er... Current state: - I have a repository on git hub which contains a handful of scripts (henceforth 'code') - I'm using git gui (mysysgit) - I have made commits and push's and have a vague understanding of CVS - I don't believe we will need to branch I feel that I should be able to use tags to create versions of

问题 What is the difference between <s> and <del> ? I have read here that there are semantic differences between <b> and <strong> , does this apply to <s> and <del> ? Additionally, how are such semantic differences, if any, interpreted by search engines and what affect would they have on rankings?

The <s> represents contents
