• What technologies are used for Game development now days?

  - by Monika Michael

  Whenever I ask a question about game development in an online forum I always get suggestions like learning line drawing algorithms, bit level image manipulation and video decompression etc. However looking at games like God of War 3, I find it hard to believe that these games could be developed using such low level techniques. The sheer awesomeness of such games defy any comprehensible(for me) programming methodology. Besides the gaming hardware is really a monster now days. So it stands to reason that the developers would work at a higher level of abstraction. What is the latest development methodology in the gaming industry? How is it that a team of 30-35 developers (of which most is management and marketing fluff) able to make such mind boggling games? If the question seems too general could you explain the architecture of God of War 3? Or how you would go about producing a clone? That I think should be objectively answerable.

• Does GNC mean the death of Internet Explorer?

  - by Monika Michael

  From the wikipedia - Google Native Client (NaCl) is a sandboxing technology for running a subset of Intel x86 or ARM native code using software-based fault isolation. It is proposed for safely running native code from a web browser, allowing web-based applications to run at near-native speeds. (Emphasis mine) (Source) Compiled C++ code running in a browser? Are other companies working on a similar offering? What would it mean for the browser landscape?

• Django: Overriding the clean() method in forms - question about raising errors

  - by Monika Sulik

  I've been doing things like this in the clean method: if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']: raise forms.ValidationError('The type and organization do not match.') if self.cleaned_data['start'] > self.cleaned_data['end']: raise forms.ValidationError('The start date cannot be later than the end date.') But then that means that the form can only raise one of these errors at a time. Is there a way for the form to raise both of these errors? EDIT #1: Any solutions for the above are great, but would love something that would also work in a scenario like: if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']: raise forms.ValidationError('The type and organization do not match.') if self.cleaned_data['start'] > self.cleaned_data['end']: raise forms.ValidationError('The start date cannot be later than the end date.') super(FooAddForm, self).clean() Where FooAddForm is a ModelForm and has unique constraints that might also cause errors. If anyone knows of something like that, that would be great...

• Am I under risk of CSRF attacks in a POST form that doesn't require the user to be logged in?

  - by Monika Sulik

  I'm probably being a total noob here, but I'm still uncertain about what a CSRF (Cross-Site Request Forgery) attack is exactly. So lets look at three situations... 1) I have a POST form that I use to edit data on my site. I want this data to be edited only by users that are logged in. 2) I have a site, which can be used by both users who are logged in as well as guests. Parts of the site are for logged in users only, but there are also POST forms that can be used by all users - anonymous and not (for example a standard contact form). Should the contact form be safeguarded against CSRF attacks? 3) I have a site which doesn't have an authentication system at all (well, perhaps that's unrealistic, so lets say it has an admin site which is separate from the rest of it and the admin part is properly safeguarded). The main part of the site is only used by anonymous users. Do the POST forms on it need to be safeguarded? In the case of 1) the answer is clearly yes. But in the case of 2 and 3 I don't know (and is the difference between 2 and 3 even significant?).

• PIP: how do I install a python package into a different directory?

  - by Monika Sulik

  I know the obvious answer is to use virtualenv and virtualenvwrapper, but for various reasons I can't/don't want to do that. So how do I modify this command: pip install package_name to make pip install the package somewhere other than the default site-packages?

• How to clone a mercurial repository over an ssh connection initiated by fabric when http authorizati

  - by Monika Sulik

  I'm attempting to use fabric for the first time and I really like it so far, but at a certain point in my deployment script I want to clone a mercurial repository. When I get to that point I get an error: err: abort: http authorization required My repository requires http authorization and fabric doesn't prompt me for the user and password. I can get around this by changing my repository address from: https://hostname/repository to: https://user:password@hostname/repository But for various reasons I would prefer not to go this route. Are there any other ways in which I could bypass this problem?

• How to access valuestack objects within struts iterator?

  - by Monika Michael

  I have following code - <s:iterator value="reviews"> <img src="<s:property value="#request.restaurant.portalImage.url" />" /> <s:property value="user.firstName" /> <s:property value="user.lastName" /> <s:property value="rating" /> <s:property value="review" /> </s:iterator> reviews is a list of review objects which contain details of a review, such as rating and name of user. My problem is that i'm not able to access any of the objects present on the valuestack within the loop. Outside the loop <s:property value="#request.restaurant.portalImage.url" /> works correctly. But within the loop it prints null. AFAIK an iterator pushes it's collection on the valuestack so that all ognl expressions resolve against it. But I've used # which means I'm explicitly specifying the root object for resolution. Why is it still not working?
