You know, I remember back when PDF links used to seem like torture. And yet, this one is like a breath of fresh air.

(Part of the reason is that PDF has been around long enough that better tools have evolved to replace the astoundingly awful Adobe Acrobat of yore. Thank you, Apple Preview! Thank you, Foxit Reader! Thank you... um, whoever wrote that Linux PDF reader that I can't remember the name of, but which comes with Ubuntu and just works!)

It's funny, because saying "Here's a PDF link" in response to a Scribd document is to me almost like saying "here's a WMV version" to a YouTube page.

// in fact, it's almost exactly like that, since the latter (Scribd/YouTube) is just a presentation layer for the former (PDF/WMV)

EDIT: Could the person who downmodded me please explain? I'll delete my comment afterward. Thank you.

EDIT2: After reading the two posts below, I now redact everything in this comment. :) I didn't say what I meant. I agree, I have no problems with PDFs either. However, I don't have a problem with WMVs either, since they open flawlessly in VLC. My point was that it's funny because I've gotten used to the worldview of "Oh noooo, PDF!" (and similarly, "oh noooo, WMV!"), and now it's kind of funny to see the opposite happening ("here's a PDF!" instead of screams of anguish).

Also, Paul, this is why I add a comment edit requesting clarification each time I get downmodded to 0 without a reply (and suggest my peers do likewise). Not because I disagree or find it questionable (I don't), I would simply like more feedback than that and hope it instills that habit into people reading my edit and the person who modded me down, since feedback is what makes Hacker News.

I upmodded you to balance it out, but it seems lately that some people are using downvoting to mean "I disagree", regardless of the quality of the comment. It seems that most sites with up/downvoting eventually turn into popularity contests for opinions, but I've always hoped news.yc could do better than that.

That said, I do disagree with your comment :). While I do like the Scribd reader, the problem of viewing PDF documents has been solved by a number of third party viewers which do not suck as much as Adobe's (as others have mentioned).

I didn't downmod you either, but I'll explain why I posted the link.

In my opinion the difference is that PDF is the lesser of two evils when it comes to PDF vs. Flash, whereas Flash is the lesser of two evils when it comes to Flash vs. WMV.

You haven't considered the difference in the formats. A key advantage of YouTube over WMV is that it loads instantly, makes streaming-while-it-downloads simple and transcodes into a quick-to-load low-bitrate version, which just completely doesn't apply to PDF - viewing PDFs using Scribd actually makes things slower and more clumsy /not/ faster or more accessible from my end. PDF is also a open format, a de facto standard and cross-platform compared to multiple codecs for video which can make life harder than necessary for viewers. Another key difference is that Scribd is used by the site as an unwanted front-end to content readily available elsewhere - compare this to YouTube which is often the exclusive host of their content and so there isn't a choice.

FWIW, when an alternate format is available for a YouTube link I often use them too as it makes life easier for managing windows or deciding to keep on the desktop knowing I won't need a net connection or have to buffer later. A recent example was John Resig's talk on the future of jQuery which was available as a download on Vimeo.

I agree, and that's not what I meant by my comment. I agree it was poorly worded. Read my second edit. Thanks for the reply!

I didn't downmod you (nor can I, heh), but...

PDFs don't bother me at all. Years ago I would occasionally accidentally click on one and be filled with dread and loathing as the Adobe Reader plugin slugged to life, but that was a long time ago. I use Safari's PDF reader now, which does what and (more importantly) behaves like I expect it to.

Scribd documents don't behave like I expect them to. Pressing down arrow scrolls further than I expect it to, mousescroll is cadenced differently (and jumps around), and I can't press space to page down.

Scribd is definitely a solution to some problems, but—for me—reading PDFs is not one of them.

I have to agree... Safari + Preview provides for a much better user experience than any other combo. Adobe Acrobat/Reader is what most of the Win people have to suffer trough understandably might appreciate alternatives. I just don't think Flash-bases stuff is much better (even though Scribd has done a great job and pushed the tech to its max).

Thank you! Scribd is quite annoying for viewing PDFs with the non-native behavior, the flash plugin which I block by default, and the inability to save easily for future reference.

I hope people directly link PDFs in the future. Thanks.

> I hope people directly link PDFs in the future. Thanks.

FYI, at one point hacker news would change PDF links to Scribd links automatically. There was a poll about it a while back.

Well, perhaps the time has come to write a Firefox plugin that automatically coverts Scribd links to PDFs.

Thank you!!! Why couldn't this be done in normal HTML?

Let me add two more:

<Alt> <.> brings out the last argument of the last command, and can be pressed multiple times.

<Alt> </> prints the contents of the cwd, or the directory from the path you're typing.

This is fabulous for us recovering Windows users. Thanks!

On the front page? C'mon this is kindergarden stuff! I thought this was Hacker News. :-)

Kindergarden sure has progressed since last time I went there!

Hey, Barack Obama started preparing in Kindergarten to become President. Kindergarten's no time for slacking.

Huh, interesting (well, for me), that guy's business is about 500 meters from my parents' house in Eugene.
