It became very hard to use due to Java security problems, and even when it works it's ancient and impractical for 2014.
<p>
To replace it I wrote a brand new replacement using CoffeeScript and WebGL canvas. It should work in most browsers, and I hope it's useful!
<p>
I call it <b>Roofpig</b>, and when I've made it presentable and stable enough I'll open source it on Github. Should only take a couple of weeks.Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com3tag:blogger.com,1999:blog-2169979466038023864.post-42619618944084178192011-03-03T14:11:00.000-08:002011-03-03T14:11:20.375-08:00Like me!I added a Facebook Like button.Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com0tag:blogger.com,1999:blog-2169979466038023864.post-3924981758763599422011-02-03T20:02:00.000-08:002011-02-03T20:02:03.797-08:00New Java AppletIt took a while, but now the new applet is used everywhere on the site. The visible differences are a much smoother look and animation.<br />
<br />
There was a problem on MacOS 10.5 browsers that took a long time to figure out.<br />
<br />
Now that it's all on the same applet, I can get to some other improvements.Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com0tag:blogger.com,1999:blog-2169979466038023864.post-57694169233954781162010-06-09T15:43:00.000-07:002010-06-09T15:43:26.067-07:00Step 6: Better "target" explanation. New Java applet version.As you may have noticed the "target" concept in <a href="http://lar5.com/cube/fas6.html">Step 6</a> has been suffering from my far too wordy and abstract explanation. I wonder how many actually managed to learn from it...<br />
<br />
Anyway, I think the new explanation is much better since it is visual. See <a href="http://lar5.com/cube/fas6.html">for yourself</a>.<br />
<br />
To show the <b>X</b> marks I'm using a new version of the applet I'm working on. Once it's stable I'll put the source code on the Downloads page, but it'll take a few months.Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com2tag:blogger.com,1999:blog-2169979466038023864.post-45759986107383595822010-02-05T15:23:00.000-08:002010-02-05T15:23:48.468-08:00Better bad edge explanation and written algorithmsThis time I've tried to fix 2 of the biggest problems with the site.<br />
<br />
<b>1. The "bad edge" explanation.</b> The good/bad edge concept, which is really the simplest part of the entire method, has been one of the hardest to understand, since my explanation was so complex and abstract. So I simplified the text and added some much needed pictures. I also fixed the existing picture, which for 10 years have shown an impossible position with 3 bad edges! Only 4 people have pointed that out aver all these years, the first was Gilles Roux.<br />
<br />
<b>2. The lack of written algorithms.</b> I've never liked cube notation. To me cubing is something you do with your hands, not something you read. Also, it's really tough for a beginner to have to learn a new language at the same time as learning the cube. But many expert cubers use notation a lot, so I have put it in on the "expert" pages. That is, the index pages and the step 4b page. I should add it to the http://lar5.com/cube/270/ pages too, but that's a <b>lot</b> of work, so it'll have to wait...Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com1tag:blogger.com,1999:blog-2169979466038023864.post-60207111376096566872010-01-20T12:11:00.000-08:002010-01-20T12:11:38.002-08:00Big site redesignIt's not easy to tell, but I just did the biggest redesign of the site ever! Mostly I replaced old and sad HTML with modern CSS based stuff. Hundreds of TABLE, FONT and CENTER tags were put to sleep!<br />
<br />
The visible changes are mostly marginal:<br />
<br />
<ul><li>The navigation at the top and ads at the bottom are now fixed to the browser frame. </li>
<li>The index navigation is the most <a href="http://lar5.com/cube/yMain.html">different look</a>.</li>
<li>And I made this change blog...</li>
</ul><br />
Over all, the site should look better now, unless you use a real old browser, but let me know if some things look weird. My testing in Internet Explorer has been especially slim.<br />
<br />
I hope to make more changes fairly soon, but I'm not making promises...Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com0tag:blogger.com,1999:blog-2169979466038023864.post-28848089746479104792010-01-12T14:47:00.000-08:002010-01-12T14:47:21.043-08:00More colorful colors!The first entry is about an update I made on Dec 5 2009.<div><br />
</div><div>The change is purely presentational. Wherever sticker colors are referred in the text, they now show up in that color. </div><div><br />
</div><div>Before: <span style="font-family: Verdana, sans-serif;">Pair corner with blue-orange edge.</span></div><div><br />
</div><div>After: <span style="font-family: Verdana, sans-serif;">Pair corner with </span><span class="Apple-style-span" style="background-color: #3d85c6;"><span style="font-family: Verdana, sans-serif;">blue</span></span><span style="font-family: Verdana, sans-serif;">-</span><span class="Apple-style-span" style="background-color: orange;"><span style="font-family: Verdana, sans-serif;">orange</span></span><span style="font-family: Verdana, sans-serif;"> edge.</span></div><div><span style="font-family: Verdana, sans-serif;"><br />
</span></div><div><span style="font-family: Times, 'Times New Roman', serif;">This may seem like a gimmick, but it makes the text less abstract and makes it easier at least for me to follow the descriptions. I hope I'm not too unique in that regard.</span></div>Lars Petrushttp://www.blogger.com/profile/05347693882147723364noreply@blogger.com0tag:blogger.com,1999:blog-2169979466038023864.post-70727788685286684302010-01-12T14:38:00.000-08:002010-01-12T14:38:08.641-08:00Welcome!<span style="font-family: 'Lucida Grande'; font-size: small;"><span class="Apple-style-span" style="font-size: 11px;">People of Earth:</span></span><div><span style="font-family: 'Lucida Grande'; font-size: small;"><span class="Apple-style-span" style="font-size: 11px;"><br />
