  FYI: Anything you upvote get's "saved" for you. Just click on your name, find the "saved" link, and it will show you all the things you upvoted for easy reference. =)

  In addition to the note by jasonlotito on 'saved' items in HN, why not save bookmarks in your browser, in social bookmarking services like http://delicious.com http://delicious.com, or on services like http://instapaper.com http://instapaper.com? Probably a better solution than leaving comments all over the place :)

    Good question. I know the reason I don't use those services, and why I find even bookmarking to be troublesome. Please keep in mind, what follows is my perspective on things. =) Here's the thing, there are two types of bookmarks: Daily and Archive. Daily bookmarks are things I want to visit often. I have a Tech News book marks collection, and other book marks I for Documentation, and one for work (amongst a few others). I keep them organized as best I can, and they don't get changed much. I use the browser bookmarks for that. I also have Archive links. These are links I want to keep, but reference later. Maybe. Not sure. I want to remember them. I use Delicious to store that. But honestly, I haven't really used it for retrieval. It's also annoying. I click the bookmarklet, and it pops up a window, and takes some basic defaults, but won't just use any default tags. It's annoying clicking all those tags. Then there is the other issue. I'll remember this article was found via HN, so I'll think HN when I think of this article. At the very least, I'll have it stored here. Instapaper is also yet another bookmarking service I'd have to use. So, now I have bookmarks in my browser, Delicious, HN Saved, and instapaper. It's a mess. Here is what I'd want: * A bookmarking/archiving system that saves locally and to the cloud. I can use something like Dropbox or Live Sync to move the archive to other computers. The system really needs only save the links. * I want to click the bookmark button and have it work. I don't want to 'install' a bookmarklet. Hook into the browser's existing functionality. An addon that adds another button is annoying as well. I have too much cruft in my chrome as it is. * I want the service to intelligently determine what keywords to use. I want it to save the article. The entire article, pages 1 through 8 if need be. As it is it's still easier just to trust search engines will find what I need or want. Most often, I can google my way to victory much quicker than I can find where I put the bookmark. Anyways, these are just my thoughts on an annoyance. You might ask why I don't tackle this problem. The thing is, I just don't have any interest in doing it. So maybe someone can make this work like it should. I haven't found a solution that works like I'd want.

      [* A bookmarking/archiving system that saves locally and to the cloud. I can use something like Dropbox or Live Sync to move the archive to other computers. The system really needs only save the links.] What I currently use for this kind of stuffs (I'm on OSX) it's shovebox+dropbox. http://www.wonderwarp.com/shovebox/ http://www.wonderwarp.com/shovebox/ It has even an iphone client but I've never tried it. Configuring shovebox to have his datafiles under the dropbox directory is a simple "ln -s" one time step, and then you can drop in this OSX menulet the links that can be save as bookmark or as a view of the page (available offline). It even allows to jot text note in it. Thanks to dropbox I have my work machine and my home machine in sync. A nice little product, it's not THE perfect solution for me, but it's the best I've found.

        I just use Google Docs, store the links I find per week using date and now I have it everywhere I go. Easily searchable as well.

      Xmarks or another bookmarking syncing system seems like exactly what you're looking for, minus automatic tags. All it does is take your browsers bookmarks and store them in the cloud, so no additional work is needed when you bookmark. Xmarks also has a rather nice mobile interface as well.

  I read and enjoyed (the complete) the article as well, I guess that I should have added that note.

Neat. When you're ready for more, be sure to check out http://courses.csail.mit.edu/iphonedev/ http://courses.csail.mit.edu/iphonedev/ for a quick dive into Objective-C + iPhone SDk. Then to get a non-trivial Hello World, check out this:http://www.stanford.edu/class/cs193p/cgi-bin/drupal/downloads-2010-winter http://www.stanford.edu/class/cs193p/cgi-bin/drupal/download...

  Thanks for those links - both of those plus the OP's post look really instructive for Objective C noobs like me.

Yuck! After all these years of high level languages, having to use a mid-level language like objective-c to develop for iPhone feels like a step backwards! If only HTML5 / phonegap was more of a viable option.
- jasongullickson 16y ago
  What's not viable about HTML5/phonegap?
  - al_james 16y ago
    Speed and user experience! Fullscreen Webkit animations are normally jerky and slow. Trying to do any form of complex graphics (canvas bitmap data for example) is a no hoper. Overall phonegap applications (at least the ones I have seen) are just not as polished as native ones.

      Interesting, a lower level programming language (Objective-C) is faster than a higher level programming language (Javascript). Who would've guessed?
- glhaynes 16y ago
  If I had to choose between Objective-C + Cocoa Touch vs. HTML5 + the-best-HTML-framework(s)-that-exist-in-2010, I'd certainly choose the former.
- xsmasher 16y ago
  I'm finding Objective-C to be a powerful addition to C and refreshingly simple compared to C++. What are you comparing it to, and what should I be missing?
  - chrisa 16y ago
    I mostly program in ruby, but have been working with objective-c more lately, so I can try to summarize what my thinking with a few examples: - Why do I have to begin every string with @? I know the technical reason why, and the difference between having it and not having it, but I don’t want to type it all the time. - Every time I type CGRectZero as an argument, I think "the method should just assume I want a CGRectZero, and if not, then I’ll tell it otherwise" - It's distracting to my thought process to surround everything with []. That could just be a result of not spending enough time in the language - Typing the name of every argument becomes tiresome after a while. Auto-complete does help some. - I don’t see it in this example, but I often see cases which alloc an object, set another object to that object (usually doing some data massaging in the process), and then release the first object. In ruby, it would be a single (short) line. I think (hope) that as I get better with the language, many of those annoyances fade away. Looking at it now, I think I could summarize it all with: The default of objective-c is to be verbose, and the default for ruby is to be terse. edit: the "alloc, set, release" paradigm can be found in part 2, step 1.
