  • What would the ultimate developer training class look like?

    - by user652273
    I think today's typical/traditional 3-5 days developer training classes aren't so great, as you tend to forget half of it shortly after. It's too much one way communication and not enough interaction. Also brain research has shown that this kind of setup is usually not optimal for efficient learning. For clarification, I am referring to professional, commercial, paid classes. However this could also be applied for any kind of studies. How could the ultimate developer training package be setup to really make sure you learn what you are supposed to learn? Would that be more: Multimedia? Exercises? Homeworks? Spread out over time instead of 3-5 compact days? Group projects?

  • How to ramp up my data structures skills after a long hibernation

    - by Anon
    I was pretty good with algorithms and data structures once, a long long time ago. Since then, I programmed professionally, and then went to manage a small team, which totally shot my tech skills in this field back. I've decided I want to be a developer again, and work for Google. The thing is, I'm so out of practice, that if I were to be interviewed right now I would surely flunk out in 10 minutes. What training program would you recommend for me to get back into shape? I already started this weekend by going back to the absolute basics and implementing a few sort algorithms, linked list, and hash table. Next, I think I'll read through the entire course material on the other basic data structures and graph algorithms. I want to find a focused set of practical exercises I can do in a relatively short amount of time, to juggle the old brain cells. I know this stuff - I just need to remind myself that I know it.

  • Do you think code is self documenting?

    - by Desolate Planet
    This is a question that was put to me many years ago as a gradute in a job interview and it's nagged at my brain now and again and I've never really found a good answer that satisfied me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

  • Some Early Considerations

    - by Chris Massey
    Following on from my previous post, I want to say "thank you" to everyone who has got in touch and got involved – you are pioneers! An update on where we are right now: paper prototypes v1 To be more specific, we’ve picked two of the ideas that seem to have more pros than cons, turned them into Balsamiq mockups, and are getting them fleshed out with realistic content. We’ll initially make these available to the aforementioned pioneers (thank you again), roll in the feedback, and then open up to get more data on what works and what doesn’t. If you’ve got any questions about this (or what we’re working on right now), feel free to ask me in the comments below. I’ve had a few people express an interest in the process we’re going through, and I’m more than happy to share details more frequently as we go along – not least because you, dear reader, will help us stay on target and create something Good. To start with, here’s a quick flashback to bring you all up to speed. A Brief Retrospective As you may already know, we’re creating a new publishing asset specifically focused on providing great content for web developers. We don’t yet know exactly what this thing will look like, or exactly how it will work, but we know we want to create something that is useful different. For my part, I’m seriously excited at the prospect of building a genuinely digital publishing system (as opposed to what most publishing is these days, which is print-style publishing which just happens to be on the web). The main challenge at this point is working out our build-measure-assess loop to speed up our experimental turn-around, and that’ll get better as we run more trials. Of course, there are a few things we’ve been pondering at this early conceptual stage: Do we publishing about heterogeneous technology stacks from day 1, or do we start with ASP.NET (which we’re familiar with) & branch out later? There are challenges with either approach. What publishing "modes" are already being well-handled? For example, the likes of Pluralsight, TekPub, and Treehouse have pretty much nailed video training (debate about price, if you like), and unless we think we can do it faster / better / cheaper (unlikely, for the record), we should leave them to it. Where should we base whatever we create? Should we create a completely new asset under a new name, graft something onto Simple-Talk (like the labs), or just build something directly into Simple-Talk? It sounds trivial, but it does have at least some impact on infrastructure and what how we manage the different types of content we (will) have. Are there any obvious problems or niches that we think could address really well, or should we just throw ideas out and see what readers respond to? What kind of users do we want to provide for? This actually deserves a little bit of unpacking… Why are you here? We currently divide readers into (broadly) the categories: Category 1: I know nothing about X, and I’d like to learn about it. Category 2: I know something about X, but I’d like to learn how to do something specific with it. Category 3: Ah man, I have a problem with X, and I need to fix it now. Now that I think about it, I might also include a 4th class of reader: Category 4: I’m looking for something interesting to engage my brain. These are clearly task-based categorizations, and depending on which task you’re performing when you arrive here, you’re going to need different types of content, or will have specific discovery needs. One of the questions that’s at the back of my mind whenever I consider a new idea is “How many of the categories will this satisfy?” As an example, typical video training is very well suited to categories 1, 2, and 4. StackOverflow is very well suited to category 3, and serves as a sign-posting system to the rest. Clearly it’s not necessary to satisfy every category need to be useful and popular, but being aware of what behavior readers might be exhibiting when they arrive will help us tune our ideas appropriately. < / Flashback > We don’t have clean answers to most of these considerations – they’re things we’re aware of, and each idea we look at is going to be best suited to a different mix of the options I’ve described. Our first experimental loop will be coming full circle in the next few days, so we should start to see how the different possibilities vary between ideas. Free to chime in with questions and suggestions about anything I’ve just brain-dumped, or at any stage as we go along. If you see anything that intrigued or enrages you, or just have an idea you’d like to share, I’d love to hear from you.

  • I'm going to quit my job because of our platform: how can I leave a productive explanation of this?

    - by Sean M
    I'm planning on leaving my current job because we're locked into using Blub, with an enterprise Blub framework and a Blub-level web server, on mediocre shared hosting. My coworkers are friendly and my boss is an average small business owner - I want to leave entirely because of the technical reasons. I feel like being soaked in Blub is bad for my brain and making me a worse programmer. When I leave, how can I explain this to my boss and coworkers? How can I phrase my complaints about Blub productively? What kind of warning can I and should I leave for my successor in documentation? (trying to make sure I meet the standards)

  • Abstract skill/talent system implementation

    - by kiliki
    I've been making small 2D games for about 3 years now (XNA and more recently LWJGL/Slick2D). My latest idea would involve some form of "talent tree" system in a real time game. I've been wracking my brain but can't think of a structure to hold a talent. Something like "Your melee attack is an instant kill if behind the target" I'd like to come up with an abstract object rather than putting random conditionals into other methods. I've solved some relatively complex problems before but I don't even know where to begin with this one. Any help would be appreciated - Java, pseudocode or general concepts are all great.

  • 3D mobile game development [on hold]

    - by SCM
    I am not a developer or programmer and, I am planning an educative project that will involve having students to develop a cross-platform, 3D mobile game, similar to the SimCity concept. I need to write a project requirement and I'd like to pick someone's brain to understand what's involved in developing such a project: -Is it realistic to have one or two students to do it? and along their other modules at uni? - How much time can it take to develop from scratch? - what are the different skills required? Thank you All SCM

  • Why not write all tests at once when doing TDD? [closed]

    - by RichK
    Possible Duplicate: Why not write all tests at once when doing TDD? The Red - Green - Refactor cycle for TDD is well established and accepted. We write one failing unit test and make it pass as simply as possible. What are the benefits to this approach over writing many failing unit tests for a class and make them all pass in one go. The test suite still protects you against writing incorrect code or making mistakes in the refactoring stage, and code coverage should be just as high, so what's the harm? Sometimes it's easier to write all the tests first as a form of 'brain dump' to quickly write down all the expected behavior in one go.

  • How will I know when my company is ready to receive an investment? [migrated]

    - by gunshor
    How will I know when my company is ready to receive an investment? I am starting a company and have bootstrapped it so far. I have produced four versions of the demo. The first fully-working version is underway. Getting this to a beta phase product will require capital, which requires an investment, which requires an investor, which requires I stop working on the product and go out and talk to people about it. The last time I raised money from investors, it took a while but I was successful. I don't want it to take a while. I want it to be brain dead simple for an investor to understand the value so that I can optimize the time I spend with the product. Is my logic flawed? What is the best way to approach raising money, while limiting both my time and risk? Thanks.

  • Programming vs Planning

    - by MattW
    Recently I have been tasked with more High level planning assignments due to the lead developer of my team leaving. I hate long term planning. My brain just doesn't naturally seem wired for it and I am not interested enough in it to spend the time to learn it (it is hard enough to keep up with the programming side of the picture). Can I still be a good programmer without being a high level planer too? Are you expected to be good at planning out the entire product and picking a date, as part of being a senior programmer. Is it possible to be a good programmer and not a high level planner?

  • I need some help creating a non-binary tree (or some other data structure that will better solve my problem)

    - by EDO
    I have about ten lists of numbers and some strings. Each list has about <= 30K lines. Each line on a list has a distinct number. I need to build an efficient way of finding all the lines in each list that has the same 'control' number (or key for dB guys) and comparing what is in their string parts. I am writing this in Java. I have thought about using trees but my brain cells are about burnt now. I need some help.

  • Great F# getting started online book

    - by MarkPearl
    So I have been battling around with F# for a few weeks and it has been frustrating just getting my brain around the syntax etc. Then someone put a comment on my blog that I should check out the following online book called the F# Survival Guide. I highly recommend those wanting to get into the basics of the language to go through this resource. It is easy to understand, especially for someone coming from a C# background. Give it a read… it gets a two thumbs up from me!

  • Checking a record is due based on the 'occuring' field

    - by andy
    I have records that have dates against them and an occurring field that contains none,yearly and monthly id status note date last_updated occurring 1 open --- 01/01/2011 01/02/2010 yearly 2 open --- 05/05/2011 03/05/2011 monthly 3 open --- 06/06/2011 05/06/2011 none Now I need to be able to check if a record is due (the date set has passed) which works perfect if occurring is set to none but I'm unsure of how to approach it when it's set to yearly or monthly (IE: This day in the year/month has passed) So with the above records, if I had a method on the record called due? providing the status is 'open' it needs to return true every year when it's passed that date if it's not been updated within the year yet. I apologise if this is confusing but it's melting my brain just trying to think of it, let alone put it into words.

  • Issue with div image size [migrated]

    - by nextyear
    I hope this helps explain the issue I am having I have recently designed a horizontal scrolling portfolio for a client, the rights and wrongs of horizontal web design, is a sligtly seperate topic but alas the client wanted something different. Im having a real issue with the bottom div though As the monitor size is reduced its creating the browser scroll bar down the side as the div image is overlapping the monitor size. Wouldnt be such a huge issue but because of the nature of the horizontal site its producing a diagional scrolling effect. Is there away to prevent the screen expanding from the actual monitor size using css or anyother solution? I'm probably staring at the answer as I type but brain doesnt seem to be working unfortunately.

  • How to find a coding buddy

    - by Lirik
    I was reading Jeff Atwood's blog and he mentioned that he was suffering from code-paralysis (he called it analysis paralysis, but I feel like it's also code paralysis) when he didn't have a code buddy: http://www.codinghorror.com/blog/ Unfortunately I think that Jeff has set the bar a bit high, because he only works with developers who are really amazing. The only reason really amazing developers would work with me is if I was really amazing too, but sometimes I don't feel that amazing... the only thing I feel is that if I had a coding buddy I could be amazing :). I'm working on a project and I don't have many friends that are programmers, let alone friends that have time to spend on extracurricular activities. Jeff seems to have been able to find like-minded people that are actually willing to work together. I feel like I'm in a code-paralysis stage too and I need some coding buddies, where would I find some? How would I approach them?

  • REG GENERIC METHOD

    - by googler1
    Hi buddies, I had a thought on using the generic method in c# as like we do in c++. Normally a method looks like this: public static (void/int/string) methodname((datatype) partameter) { return ...; } I had a thought whether can we implement the generics to this method like this: public static <T> methodname(<T> partameter) { return ...; } Using as a generic to define the datatype. Can anyone pls suggest whether the above declaration is correct and can be used in c#? Thanks in advance.

  • Interacts with dialog/whiptail on early boot rcX.d stage?

    - by nm
    Hi buddies, I'm developing on Ubuntu based, actually I got one script in-charged on GUI(console) setup. It runs before another scripts (rcX.d) start. Currently, I installed this script on rc2.d and start earlier than other ones. But when run on real machine, I can't input any keystroke on "dialog --inputbox" or whiptail through shell script. Additionally, It runs well on my Virtual Machine (Virtual Box and Vmware), that's so strange! So, does anybody give some help or point me any clues for overcome this ? Thanks

  • C# 4: Real-World Example of Dynamic Types

    - by routeNpingme
    I think I have my brain halfway wrapped around the Dynamic Types concept in C# 4, but can't for the life of me figure out a scenario where I'd actually want to use it. I'm sure there are many, but I'm just having trouble making the connection as to how I could engineer a solution that is better solved with dynamics as opposed to interfaces, dependency injection, etc. So, what's a real-world application scenario where dynamic type usage is appropriate?
