• Looking for a good book on microprocessor internals

  - by David Holm

  I'm looking for a good book on how modern microprocessors are designed and work as I would like to increase my understanding of what makes them tick. Something that covers pipelines, superscalar architectures, caches etc. A book that is suitable for a programmer with several years of experience and has done and understands assembly programming and machine language, so basically not "CPUs for Dummies" or anything such. What books do people who design today's processors read for instance?

• What is O(n log n) or O(n log(log n))

  - by Mark Tomlin

  What does O, if indeed it is a Oh (As in the letter O) not the number Zero (0) mean? I think the n would be number, but I'm not sure as I'm not a 'real' computer programmer, just a hobbyist. And log would be logarithmic function, but I only know that because of smarter people then I have told me this, while never really explaining what a logarithm is. So please, in plain English, explain what this is, and the differences between the two (such as their applications.

• Returning IEnumerable from an indexer, bad practice?

  - by fearofawhackplanet

  If I had a CarsDataStore representing a table something like: Cars -------------- Ford | Fiesta Ford | Escort Ford | Orion Fiat | Uno Fiat | Panda Then I could do IEnumerable<Cars> fords = CarsDataStore["Ford"]; Is this a bad idea? It's iconsistent with the other datastore objects in my api (which all have a single column PK indexer), and I'm guessing most people don't expect an indexer to return a collection in this situation.

• Django : debugging templatetags

  - by interstar

  How on earth do people debug Django templatetags? I created one, based on a working example, my new tag looks the same to me as the existing one. But I just get a 'my_lib' is not a valid tag library: Could not load template library from django.templatetags.my_lib, No module named my_lib I know that this is probably because of something failing when defining the lib. But how do I see what's going on? What do you use to debug this situation?

• Visual Studio 2008 - speed up Add Reference

  - by Mauricio Scheffer

  Is there any way to speed up the Add Reference dialog? For example, has anyone found any way to open it by default in the Recent or Browse tabs (which is what I use 90% of the time), to avoid the other tabs' slowness? All I have found is this blog post where a lot of people complain about this issue, but no solutions... Note that this is not a duplicate of 8440 as this is not a general question.

• html5 video secure streaming?

  - by citizenmatt

  Does html5 allow me to do secure streaming video? And by this, I mean token authentication. I want to be able to stream media only to those people who are authorised to view it. I can do this currently with Flash Media Server hosted by Akamai - they have a custom mechanism where I send them a token as part of the player connection handshake. Does html5 allow for this, and has anyone implemented this with a hosting service such as Akamai? Thanks Matt

• Safari and the z-index flash problem

  - by Zakaria

  Hi everybody, I don't know if it's a classic safari 4 bug, but apparently many people cannot display correctly a non-flash content (div, image, etc.) over a flash animation. I tried everything: The wmode (switching from "opaque" to "transparent"), the z-index and many other div "cheats". Did anyone know if there is a safari 4 patch/trick/script to fix this problem? Thank you very much, regards.

• What are codepad.org's Perl runner limitations?

  - by Lemurik

  Sometimes I see people use http://codepad.org as a way to quickly run/test their Perl snippets (it supports doing that with a wide variety of languages, from C to Scheme to Perl). It's pretty obvious that there must be some limitations as to what code/features can be tested with codepad - does anyone know what those limitations are for Perl runner? I'll get the ball rolling on my own observation: not every CPAN module is available :(

• Are iframes a terrible idea?

  - by jamtoday

  I'm building a widget, and I've been using iframes to present content within it. At some point, I might start serving third party HTML and JS, so I thought iframes would be a good idea. It does make the widget javascript a little more complicated, and I'm concerned that this might not be the best implementation. Do you have any advice? It would be a huge help to hear what other people think about iframes.

• Why use "foo" in coding examples? [closed]

  - by ThePower

  Possible Duplicates: To foo bar, or not to foo bar: that is the question. Bit of a general question here, but it's something I would like to know! Whenever I am looking for resolutions to my C# problems online, I always come across "foo" being used as an example. Does this represent anything or is it just one of those unexplained catchy object names, used by many people in examples?

• SmartGWT alternatives

  - by Roger

  I have been using SmartGWT but have run into trouble mixing SmartGWT with other frameworks such as Wicket. Infact it has been a bit of a disaster and I regret going with it in the first place. I do not want this question to turn into any type of flame war, so therefore would just like people to list alternatives and their experience with those alternatives.

• Sparxsystems Enterprise Architect and issuses/tasks tracking system?

  - by peperg

  We (developement team 4 upto 7 people) use Sparxsystems EA for requirement analysis, modeling etc. Do you know any well-working methods to use EA and some task/issue tracking system like Redmine/Mantis/Trac ? The problem is not to duplicate functionality (there are issues/tasks/changes in Redmine and EA) but to have some user friendly interface (preffered web) to manage tasks and issues. By user-friendly I mean "my tasks" page add effort / time tracking easy "add issue" by everyone (simple bug tracking system) mail notifications

• Force sharepoint to ask for authentication

  - by amonteiro

  Is there a way to force sharepoint 2010 to popup the dialog to ask the user for a username and password and not use the computers logged in user, if that user doesn't have access. We need an internal sharepoint website to not use the windows credentials, since these are computers used by many people. The windows user doesn't have access to the site, so currently it shows an access denied, click here to log in as another user. We would prefer if it just asked for credentials in a more graceful manner.
