• Trust

  - by mprove

  I sense traffic of this blog w/o a present reason. Hmm. What about this,  brief musings about trust: Each software, each website, each social platform, each community building effort is a matter of trust building. You make a social promise to continue the effort, and to care for the commitment of the users or community members. It is easy to offer more to your community. On the other hand, it is quite difficult or impossible to take something away, or to close down or end the product or community without disappointing someone. cheers,Matthias

• Releasing poorly written software...

  - by eddienotizzard

  I've made a poorly written, yet fully functioning website, in (shock, horror, shock) PHP. Everything works as expected, I've implemented the necessary security measures: http://php.net/manual/en/security.php and phpsec.org/projects/guide/ It's poorly written in the sense that it's a bunch of functions thrown together that do something...oddly enough I was consistent with the naming conventions. Would you release something you were not happy with, but worked? I would also like to point out that I don't collect much user information (username, email and password) is about it -- but it's not really the security part I'm worried about, it's the spaghetti code I've written.

• Software bug/defect classification

  - by Dustin K

  We're trying to come up with terms that better describe our bugs/defects. To us, the term 'bug' or 'defect' is too generic and doesn't accurately reflect what is happening. For example, instead of saying that there is a bug (in the general sense), we'd rather say what type of bug (an error, or enhancement, or improvement, etc.). What names do you use for describing 'bugs'? We found http://www.softwaredevelopment.ca/bugs.shtml which has some pretty good classifications. How do you classify them?

• Is it possible to map mouse coordinates to isometric tiles with this coordinate system?

  - by plukich

  I'm trying to implement mouse interaction in a 2D isometric game, but I'm not sure if it's possible given the coordinate system used for tile maps in the game. I've read some helpful things like this. However, this game's coordinate system is "jagged" (for lack of a better word), and looks like this: Is it even possible to map mouse coordinates to this successfully, since the y-axis can't be drawn on this tile-map as a straight line? I've thought about doing odd-y-value translations and even-y-value translations with two different matrices, but that only makes sense going from tile to screen.

• What is the relevance of resumes in the age of GitHub, Stack Exchange, Coursera, Udacity, blogs, etc.?

  - by davidk01

  My resume is no longer relevant. It can no longer contain an adequate description of my technical abilities. One can get a much better sense of what I am capable of by looking at my GitHub repositories, my Stack Exchange profiles, and the various courses that I am taking at Udacity and Coursera. The problem is that I have no idea how to tell employers that those are the places to look if they want an accurate description of what I can do. Every time a recruiter contacts me I gently nudge them towards all the resources I just mentioned and I also provide a link to a publicly visible Google doc that contains my resume along with links to all those resources. Yet, they keep coming back asking for a more descriptive resume. How can I make it even more blatantly obvious that if somebody wants to hire me then they can save themselves a whole bunch of trouble by just clicking on a few links and browsing around?

• Is deserializing complex objects instead of creating them a good idea, in test setup?

  - by Chris Bye

  I'm writing tests for a component that takes very complex objects as input. These tests are mixes of tests against already existing components, and test-first tests for new features. Instead of re-creating my input objects (this would be a large chunk of code) or reading one from our data store, I had the thought to serialize a live instance of one of these objects, and just deserialize it into test setup. I can't decide if this is a reasonable idea that will save effort in long run, or whether it's the worst idea that I've ever had, causing those that will maintain this code will hunt me down as soon as they read it. Is deserialization of inputs a valid means of test setup in some cases? To give a sense of scale of what I'm dealing with, the size of serialization output for one of these input objects is 93KB. Obtained by, in C#: new BinaryFormatter().Serialize((Stream)fileStream, myObject);

• What is the most complicated data structure you have used in a practical situation?

  - by Fanatic23

  The germ for this question came up from a discussion I was having with couple of fellow developers from the industry. Turns out that in a lot of places project managers are wary about complex data structures, and generally insist on whatever exists out-of-the-box from standard library/packages. The general idea seems to be like use a combination of whats already available unless performance is seriously impeded. This helps keeping the code base simple, which to the non-diplomatic would mean "we have high attrition, and newer ones we hire may not be that good". So no bloom filter or skip-lists or splay trees for you CS junkies. So here's the question (again): Whats the most complicated data structure you did or used in office? Helps get a sense of how good/sophisticated real world software are.

• Octrees as data structure

  - by Christian Frantz

  In my cube world, I want to use octrees to represent my chunks of 20x20x20 cubes for frustum and occlusion culling. I understand how octrees work, I just dont know if I'm going about this the right way. My base octree class is taken from here: http://www.xnawiki.com/index.php/Octree What I'm wondering is how to apply occlusion culling using this class. Does it make sense to have one octree for each cube chunk? Or should I make the octree bigger? Since I'm using cubes, each cube should fit into a node without overlap so that won't be an issue

• T9 patented while QWERTY is not?

  - by Marco W.

  I've seen that there are lots of custom keyboards for Android, but all are QWERTY keyboards. I couldn't find any keyboard with T9 layout. Is this because T9 is patented and the QWERTY layout is not? So if I made a T9 keyboard, I would have to pay patent fees? So what does the patent protect when you look at T9? Only the layout? Or the prediction engine? The problem is, this way of predicting words is the only one that makes sense for this layout ...

• photshop: why low quality jpg saved as high quality increases the file size?

  - by Alex Angelico

  i have a low quality background about 85kb. If I open the file in Photoshop and save it, I have to save this image as 100% quality, the file size increases to 640kb. This doesn't make sense, the image si already compressed, the quality cannot be better than the source, so the 100% quality while saving should produce THE SAME FILE OPENED. The problem is, I have this background and want to add a logo image over it, and then save it. But If I do so, i have to save this with 10% quality, and the logo looks horrible. If I save this to 100% quality, the file size is huge... How can I achive this?

• My very first serious project and I'm concerned about security.

  - by ilhan

  I'm making a small social networking web site for a specific university's students (where I study) and I'm concerned about security (access to the database). What should I do? What I have to check for last time until I went online? (Yeah, Facebook Facebook. Facebook don't have that community sense. You cannot find all your department mates on Facebook. You cannot see all foreign students on Facebook. You cannot hide your identity on Facebook while commenting, etc etc. Just please don't compare it with Facebook, we had a great local social network until it went public . * ))

• PyQt design issues

  - by Falmarri

  I've been working on a my first real project using PyQt lately. I've done just a little bit of work in Qt for C++ but nothing more than just messing around. I've found that the Qt python bindings are essentially just a straight port of C++ classes into python, which makes sense. The issue is that this creates a lot of messy, unpythonic code. For example if you look at QAbstractItemModel, there's a lot of hoops you have to go through that forces you to hide the actual python. I was just wondering if there's any intention of writing a python implementation of Qt that isn't necessarily just a wrapper? Either by Nokia or anyone else? I really like Qt but I would love to be able to write more pythonic code. I hope this is OK to ask here. I'm not trying to start a GUI war or anything.

• Intro to NoSQL with RavenDB

  - by dgreen

  I did a talk on RavenDB back on 9/19/2012. Here was my abstract: "RavenDB is a document database which is gaining popularity in the 'NoSQL' movement. This session will introduce you to some non-relational concepts and describe how they compare/contrast with the relational solutions you're already familiar with. We'll go through the basics of RavenDB and show how easy it is to use from .NET” My next goal is to figure out how to post the slidedeck here (and maybe the code samples if I'm feeling ambitious). Then, the slides can be downloaded for only three easy payments of $39.99. However  for this one time special offer they are currently being given away absolutely FREE with a signup to http://meetup.trinug.org Footnote: I probably shouldn't have to say this, but my last comment about charging for my slidedeck was a joke. I have an odd sense of humor for those who don't already know me :)

• Developing an AI opponent for Monopoly

  - by Bernhard Zürn

  i want to develop an AI opponent for the Board Game Monopoly. I want to implement the whole Game with Prolog (XPCE). The probability for a field on the Board being hit, can be computed with Markov Chains. I already know some "best practices" like "after 50% of the playing time it does not make sense to buy out of jail because in jail you get renting fees for your fields but you don't have to pay for other fields as long as you stay in prison". The interesting question always is: buy a streetfield ? buy houses / hotels ? how much ? so i think i would have to compute some kind of future liquidity .. does anyone know how to pack that into an algorithm or how to translate it to prolog ?

• What are the pros and cons of non-unique display names?

  - by Davy8

  I know of at least big title game (Starcraft II) that doesn't require unique display names, so it would seem like it can work in at least some circumstance. Under what situations does allowing non-unique display names work well? When does it not work well? Does it come down to whether or not impersonation of someone else is a problem? The reasons I believe it works for Starcraft II is that there isn't any kind of in-game trading of virtual goods and other than "for kicks" there isn't much incentive to impersonate someone else in the game. There's also ladder rankings so even trying to impersonate a pro is easily detectable unless you're on a similar skill level. What are some other cases where it makes sense to specifically allow or disallow duplicate display names?

• Should a developer always use version control

  - by kurtnelle

  I've heard statements to the effect of: "Well it's just me working on this project so I don't need to put it under source control" as well as, "There is no need to work version controlled on this project, it's so small". It is my opinion that no matter how small the project is, so long as it's adding value to the client (and they are paying for it too) that we, the developer(s), should version control it; especially since its company policy. Am I insane or does my standpoint make sense. Question: Should development work always be version controlled?

• Steps after SQL Injection detected

  - by Zukas

  I've come across SQL injection vulnerabilities on my companies ecommerce page. It was fairly poorly put together. I believe I have prevented future attempts however we are getting calls about fraudulent credit card charges on our site and others. This leads me to believe that someone was able to get a list of our credit card numbers. What doesn't make sense is that we don't store that information and we use Authorize.net for the transaction. If someone was able to get the CC#s, what should I do next? Inform ALL of our customers that someone broken into our system and stole their information? I have a feeling that will be bad for business.

• What is the best unit test framework for .NET and why?

  - by rmx

  It seems to me that everyone uses NUnit without even considering the other options. I think this is because: Everyone is familiar with it already so they won't have to learn a new API. It is already set up with their continuous integration server to work with NUnit. Am I wrong about this? I decided to use xUnit on one of my own projects recently and I love it! It makes so much more sense to me and conceptually it seems like a definite step forward from NUnit. I'd like to hear opinions on which framework is actually the best - not taking into consideration having to learn it or reconfigure your automated testing.

• Layout of experienced programmer Resume? [closed]

  - by mob1lejunkie

  What layout of resume works best for experienced programmers? Currently my layout is: Contact Details Focus (goal) Technical Skills Professional Experience (Responsibilities + achievements at each job) Education Interests I feel my current layout uses up too much valuable space. Most of the online templates feel like junior Resumes with emphasis on education so I am not sure how I can improve it. I wonder how many hiring managers actually care about goal/objective? To me it looks useless. Also, is it necessary to have summary of technical skills/technologies? If so, would it not make more sense for it to be mentioned later in the Resume rather then at the top? Finally, do you have separate section for achievements? Many thanks.

• What is the formal definition of a meta package?

  - by kojiro

  There are several examples of packaging where an application package is built, named, described, even licensed, but contains only setup code and dependencies -- it has no first-class runtime software of its own. I would call this "meta-packaging". This seems to be particularly popular in the open-source world, including examples like kde-meta (Gentoo Portage), Plone, and I'm sure lots of others. I can see how it's a useful practice, but despite it existing as a practice, I couldn't find a formal definition of either "meta-packaging" or "meta-egg" (Python) in searching the web. Is that not the correct term? If it is, is it such common-sense that it needs no formal definition? If not, what is the correct way to put it?

• Where is the best place to find stock website templates?

  - by Billy ONeal

  I think I'm in the majority of programmers in saying I can't do visual design for s***. But I do write programs occasionally, and I'd like to have a nice website to tell people about said programs. I used to use a site called "OSWD" to find templates, but it's been forever since it's been looked at, and most of the designs seem overly specifically tailored to a single kind of site -- for example, a site featuring a large picture of an ice cube wouldn't make much sense for a site displaying software for people to use. I know there are plenty of template sites out there which have freely available designs, but I'm not sure which ones are good, and which ones are garbage. Where is the best place to find website templates?

• No mention of ARM versions of Lubuntu .. on the main website?

  - by Mike

  Just a question for the Lubuntu team really - I am a huge fan of Lubuntu - thank you and congratulations on creating a great distribution. I am just surprised to notice that, the main website doesn't mention that there are ARM versions - or provide any links to download. Is that because they are 'unofficial' in some sense ? I am running Lubuntu 11.10 on an Allwinner A10 device (the MK802) and it works a treat. Don't "hide your light" guys - tell the world Lubuntu is a cracking OS for ARM systems.

• When to use C over C++, and C++ over C?

  - by Dark Templar

  I've been introduced to Computer Science for a little over a year now, and from my experience it seems that C and C++ are both considered one of the "ultrafast" languages out there, whereas others such as Python and such scripting languages are usually deemed somewhat slower. But I've also seen many cases where a software project or even a small one would interleave files where a certain number n of those files would be written in C, and a certain number m of those files would be written in C++. (I also noticed that C++ files almost always have corresponding headers, while C files not so much). But my main point of inquiry is to get a general sense of intuition on when it is appropriate to use C over C++, and when it is better to use C++ over C. Other than the facts that (1) C++ is object-oriented whereas C is not, and (2) the syntaxes are very similar, and C++ was intentionally created to resemble C in many ways, I am not sure what their differences are. It seems to me that they are (almost) perfectly interchangeable in many domains. So it would be appreciated if someone could clear up the situation! Thanks

• is jargon related to a frameWork (concept)

  - by MaKo

  If this is not the right place to ask this question please inform where it would belong, to change it... I have a doubt for the correct word or concept in english language [not my native], about the relationship of language to framework for example i work with objective C, with the cocoa touch frame work || python with the django frame work My comparison is between natural languages and formal languages, So would be in a natural language english and the frame work a [computer, it]jargon? Does this make sense? Or what other concept would be the relationship between natural language - framework?
