  • L'interview technique est-il adapté pour les recrutements ? Un développeur estime que cette pratique est ridicule et devrait mourir

    Au diable l'interview Technique d'avant embauche en entreprise Un développeur estime que cette pratique est ridicule et sa réussite tient plus de la chanceQuel programmeur ne se souvient pas de ses premiers entretiens d'embauche en entreprise ? Les mains moites, le coeur qui bat à la chamade, la gorge serrée ; ce sont là, les signes annonciateurs du stress qu'on ressent en attendant son tour. Une fois en face de son interviewer, il s'en suit une série de questions techniques qui, si on a la providence avec soi, cadre avec son domaine d'expertise. Le tout s'achève par un exercice, ou on est invité à écrire du code sur un tableau. Cependant, avec le stress accumulé lors des étapes précédentes, en est-on e...

  • How can I stay focused and motivated on a project?

    - by RTS
    I'm working on starting my own software development business, but I've noticed that I have major issues getting projects out by their deadlines, and in general getting them out of the "almost-done" stage. I feel my problem is that I like complex programming too much, and I end up rewriting code to make it cleaner/more efficient/less error prone as a means of putting off more "boring" development. I end up with polished applications at the end, but I spend twice as long on the project as I should have. If I ever want my company to succeed, I need to work on staying focused on what actually needs to be done, so the question is: What techniques do you use to keep yourself focused and motivated on a project, in your career?

  • Rendering trillions of "atoms" instead of polygons?

    - by Baring
    I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

  • How do you get users to rank their software enhancement needs?

    - by Lego Stormtroopr
    I've inherited a legacy software system, and have been tasked with performing usability and system upgrades. While there's nothing bad with the system, from discussions with the users, there are "small" usabilty issues that need to be addressed. At this stage I'm the lone developer on this system, and apart from testing I don't use the system at all, so its difficult for me to know what issues may exist or are percieved to exist. I'm going to have some time to speak with them all and discuss what they percieve to be good/bad or indifferent about the system. Since its essentially just me for the time being my time is limit. So I was considering asking them to imagine that I'd only be able to do one change, have them all write privately what they'd want that one change to be, and then helping them rank those, but I'm hoping for other tips as well. What techniques exist for getting users to explain their wants, needs, and requirements, while also having them rank them by importance or desirability?

  • Hello, World

    - by KyleBurns
    This is the obligatory first posting in which I describe to you my plans for this blog and why you should read it. My plan is very simple – to share with you (and possibly myself along the way) relevant information about tools and techniques that you can use (or perhaps shouldn’t use) to solve problems with code. Most of my employers have paid me to develop solutions using Microsoft tools and technologies, so you will see them heavily represented here. I also plan to avoid having this blog function simply as a link aggregator, so I promise that it will be rare for you to find entries in my blog consisting solely of a link to someone else’s blog or a webcast – if I do have such links they will at least be accompanied by commentary. This is my first venture into the world of blogging, so please let me know how I'm doing (be nice) and feel free to suggest/request topics for future entries.

  • Comment prenez-vous en compte l'utilisateur dans vos applications ? Pour un développeur, «90% des utilisateurs sont des idiots»

    Quelles idées avez-vous de l'utilisateur final lors du développement d'une application ? Un développeur choisi comme leitmotiv « 90 % des utilisateurs sont des idiots » L'utilisateur final est au centre des travaux du développeur, et ce tout au long du cycle de développement d'une application. En tant que cible du développeur, il est le garant du succès (ou de l'échec) d'une application. Il faut donc avoir une idée claire de ses attentes, de ses besoins et de ses aspirations techniques (simplicité ou UI foisonnante, etc.). Berf, le développeur doit faire le maximum d'efforts pour comprendre son « client ». Certains diront même qu'il faut aller jusqu'à se mettre dans la peau de l'ut...

  • How to gain understanding of large systems? [closed]

    - by vonolsson
    Possible Duplicate: How do you dive into large code bases? I have worked as a developer developing C/C++ applications for mobile platforms (Windows Mobile and Symbian) for about six years. About a year ago, however, I changed job and currently work with large(!) enterprise systems with high security and availability requirements, all developed in Java. My problem is that I am having a hard time getting a grip on the architecture of the systems, even after a year working with them, and understanding systems other people have built has never been my strong side. The fact that I haven't worked with enterprise systems before doesn't exactly help. Does anyone have a good approach on how to learn and understand large systems? Are there any particular techniques and/or patterns I should read up on?

  • As a consultant, how can I amaze my clients?

    - by user20326
    I am about to form a small consulting company and with a few friends and I am curious about how/what you do to amaze and create happy long lasting clients? This is of course besides the standard points like delivering on time, charge fair amount, deliver quality, and deliver what they really want. What other techniques do you use to amaze and create long lasting clients? (and to stand out compare to the competition) For example: Gifts? Happening and events? Night out at the pub?

  • Accessing Server-Side Data from Client Script: Using Ajax Web Services, Script References, and ...

    Today's websites commonly exchange information between the browser and the web server using Ajax techniques. In a nutshell, the browser executes JavaScript code typically in response to the page loading or some user action. This JavaScript makes an asynchronous HTTP request to the server. The server processes this request and, perhaps, returns data that the browser can then seamlessly integrate into the web page. Typically, the information exchanged between the browser and server is serialized into JSON, an open, text-based serialization format that is both human-readable and platform independent.Adding such targeted, lightweight Ajax capabilities to your ASP.NET website requires two steps: first, you must create some mechanism on

  • How to save the content in UIWebView for faster loading on next launch?

    - by erotsppa
    I know that there are some caching classes introduced in the iphone sdk recently, and there is also a TTURLRequest from three20's library that allows you to cache a request to a URL. However, because I am loading the web page in UIWebView by calling UIWebView's loadRequest, those techniques are not really applicable. Any ideas how I can save a web page so that on next app launch, I don't have to fetch from the web again for the full page? The page itself already have some ajax mechanism that updates parts of itself automatically.
