开发技术学习

记事狗V2.5版已经放出来了，虽然功能有增强了，但是底部版权去除也做了加密。
我们不难发现，原本在记事狗2.0版本中去版权的方法失效了。然而在，记事狗的官方微博中引起了对版权的一场大讨论。。。甚至屏蔽了网友对版权去除的发言。
现在我们从纯技术的角度来分析一下记事狗2.5的版权“原理”。但本文声明，此文只是技术研究，望各位读者自己掂量版权问题。我们的立场是保留版权！！！
第一步：找到modules文件夹里面的master.mod.php文件，在master.mod.php文件中找到如下代码：
$i = $this->Config['s'.'y'.'s'.'_'.'v'.'e'.'r'.'s'.'i'.'o'.'n'];
$j = “303233226″.”211337214″.”x8b206223″.”232302xdd”.”x9cx93232″.”236215305″.”x9d220213″.”x97304213″.”x9ax87x8b”.”322x9ex93″.”226x98x91″.”305234x9a”.”221213x9a”.”215xc4210″.”x96x9bx8b”.”227xc5xc7″.”317317x8f”.”207xc4x92″.”x9e215x98″.”226221xc5″.”xca217x87″.”xdf236x8a”.”213x90304″.”335301xaf”.”220x88232″.”x8d232233″.”337235x86″.”xdf303x9e”.”xdfx97x8d”.”x9a231302″.”335x97213″.”x8bx8f305″.”xd0xd0210″.”x88210xd1″.”265x96214″.”x97x96270″.”x90x8axd1″.”221x9ax8b”.”xd0335301″.”303x8c213″.”x8dx90x91″.”x98xc1xb5″.”x96x8c227″.”x96xb8x90″.”212xc3xd0″.”214x8bx8d”.”220x91x98″.”xc1303320″.”x9exc1″;
$k = “303214x8f”.”x9e221301″.”xdf331x9c”.”x90x8fx86″.”xc4337315″.”xcf317312″.”xdf322xdf”.”315317xce”.”317337xc3″.”x9exdf227″.”215232x99″.”xc2335227″.”213x8b217″.”305xd0xd0″.”210x88x88″.”xd1234x9a”.”x91x88220″.”x8dxd1x9c”.”220222320″.”xddxdfx8b”.”236215230″.”232213xc2″.”xddxa0x9d”.”x93236x91″.”224xdd301″.”274232221″.”x88220215″.”337xb6x91″.”234321xc3″.”xd0236xc1″.”303320x8c”.”x8fx9ex91″.”xc1xc3320″.”x9b226211″.”301″;
echo (~$j) . $i . (~$k);
去掉上面的代码。。。此时我们发现，版权并没有去掉。。。真毒啊！下面我们看第二步，找到templatesdefaultjscommon.js里面的如下代码：

此时再看，版权去掉了，没有了！呵呵。。。。。切记不要直接删了上面的代码，要将代码替换为我们发布的，要不然去版权就会失败。虽然帮助了网友们达到了去除版权的目的，也解了网友们对记事狗所谓的“开源”并不真实的气，最后我们还是呼吁大家：尊重别人的劳动成果，保留版权！别人也不容易啊！
