Happy to read an explanation about th...Hi Shepherd,<br />Happy to read an explanation about this CS193 swift code product from Stanford.<br />And fews bugs that have been spotted by you.<br /><br />I have a concern about one part :<br /><br />"The second inefficiency occurs when there is an axis to plot but the origin is outside the view. Suppose the origin is at (-100, 0), the view has a minimum x value of 0 and we have decided that labels will be plotted every 10 points. In this case the view will contain a portion of the a-axis starting at 100 with labels at 100, 110, etc. If the code does nothing to deal with this case, it work out from the origin and try (and fail) to plot labels at distances of 10, 20 and up to 90 points from the origin until it starts to plot at 100 points distant from the origin. An optimisation that can be done is to detect the case that the origin is outside the view<br /><br /> if !CGRectContainsPoint(bounds, origin) {"<br /><br />You are talking about the inefficiency if we are trying to plot an axis if the origin is outside the view bounds'. But i tried to understand why they wrote that in their code. If the View code is well set, we don't need it, in my view. <br /><br />For example if we are setting the origin at the View bounds.midX and bounds.midY at each time we are plotting a function. Whether we need to pan, of course, we must keep the origin of the axes. But, if we are panning out of the primordial view bounds' the starting hashmark radius seems to always compute this value of 1, the same that is set before. So what the aim ?! May be i'am wrong. I'am not a developper that the reason i'am following this kind of courses. <br /><br />Thank you if you are taking time to answer me and explain me the Why and the How, also i hope you will understand what i mean, cause i'am not an english native speaker.<br /><br />Have a good day,<br /><br />Fred.Fredhttps://www.blogger.com/profile/14158437995399130122noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-90468310641651985992015-04-11T14:23:30.974+01:002015-04-11T14:23:30.974+01:00"We can rebuild him.

If this is added in to the mix, then the overall performance goes up. Certainly not 2x for all applications - but that isn't what is being claimed.<br /><br />2. I'd say that if developing, unless you think the VFPv7s makes a big difference, don't use it. If you are using it, then either you'll have to have two versions, or you don't support the old hardware. But do undertstand - that's just my view, not Apple's advice.<br /><br />3.

If this adds only a VFPv4, then it would only help some math intensive application that uses floating point calculations heavily. But that can't be a 2X performance improvement for all applications.<br /><br />Second is, how about compatibility of applications that run on the new iphone 5 and the older ones? Should an app be compiled for iphone 5 specifically with v7s to get the most out of the A6? <br /><br />If cortex A15 was really made for servers as Anand says then why would TI, Nvidia people implement them in their SoCs intended for mobile devices?<br /><br />A lot of questions in mind. Doesn't convince me either that the core isn't a cortex A15.sundarnoreply@blogger.comtag:blogger.com,1999:blog-28021148.post-61871974748947608522012-01-02T21:41:09.576+00:002012-01-02T21:41:09.576+00:00Exercise for the reader.Exercise for the reader.The Editorhttps://www.blogger.com/profile/00750939859695685490noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-17421265201521784232012-01-01T22:37:46.975+00:002012-01-01T22:37:46.975+00:00How do we know it's you and not your phone?How do we know it's you and not your phone?Benflyboyhttps://www.blogger.com/profile/17767404683847919646noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-23157834989211387062011-07-13T00:09:44.511+01:002011-07-13T00:09:44.511+01:00Actually, the story is quite interesting as explai...Actually, the story is quite interesting as explained in the Wikipedia article <br /><br />http://en.wikipedia.org/wiki/99_Luftballons<br /><br />The orginal version says that a General sets off his jet fighters to take a look at a UFO (the balloons); the English version talks about this being due to bugs in the software.<br /><br />And sure, the toy balloons in the song weren't identified as "red" but "99 Red Balloons" does scan like "99 Luftballons".<br /><br />Great song; of its era - reminds me of the fear of nuclear war.The Editorhttps://www.blogger.com/profile/00750939859695685490noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-13086965130283706192011-07-12T23:44:53.141+01:002011-07-12T23:44:53.141+01:00I am a big fan of this song and I agree that the G...I am a big fan of this song and I agree that the German version is superior. As is true of many 80s tracks it's often better not to probe too deeply into the lyrics.

He came to fame by writing "IT Doesn't Matter" and since then has written a series of books warning us about the disastrous consequences of each advance in technology. When Gutenberg first invented printing there were plenty of older fuddy-duddies who complained that manuscripts were better and claimed that printing would only be a passing fad.

Who remembers the earthquake in Christchurch? Or the floods in Australia? Or those in Pakistan? (Etc.) - all of which are still huge disasters for the people involved. Plus (in the popular imagination) 'nuclear' is synonymous with 'enormously powerful' or 'bigger than anything else', and so a 'nuclear disaster' automatically trumps any other kind.Anonymoushttps://www.blogger.com/profile/04061645880178478052noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-63516533120713688032011-03-11T21:53:08.737+00:002011-03-11T21:53:08.737+00:00Not so goodNot so goodThe Editorhttps://www.blogger.com/profile/00750939859695685490noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-51530556853158200742011-03-08T20:14:12.778+00:002011-03-08T20:14:12.778+00:00It's way easier to blog if all you're doin...It's <b>way</b> easier to blog if all you're doing is describing your day (as I was in my skiingjim alias). <br />Now I'm back at work, I'm not blogging at all!Jim Cowniehttps://www.blogger.com/profile/05641343927746539200noreply@blogger.comtag:blogger.com,1999:blog-28021148.post-54364100898660410832011-01-22T18:16:43.011+00:002011-01-22T18:16:43.011+00:00Yup.
