  • More Quick Interview Tips

    - by Ajarn Mark Caldwell
    In the last couple of years I have conducted a lot of interviews for application and database developers for my company, and I can tell you that the little things can mean a lot.  Here are a few quick tips to help you make a good first impression. A year ago I gave you my #1 interview tip: Do some basic research!  And a year later, I am still stunned by how few technical people do the most basic of research.  I can only guess that it is because it is so engrained in our psyche that technical competence is everything (see How to Manage Technical Employees for more on this idea) that we forget or ignore the importance of soft skills and the art of the interview.  Or maybe it is because we have heard the stories of the uber-geek who has zero personal skills but still makes a fortune working for Microsoft.  Well, here’s another quick tip:  You’re probably not as good as he is; and a large number of companies actually run small to medium sized teams and can’t really afford to have the social outcast in the group.  In a small team, everyone has to get along well, and that’s an important part of what I’m evaluating during the interview process. My #2 tip is to act alive!  I typically conduct screening interviews by phone before I bring someone in for an in-person.  I don’t care how laid-back you are or if you have a “quiet personality”, when we are talking, ACT like you are happy I called and you are interested in getting the job.  If you sound like you are bored-to-death and that you would be perfectly happy to never work again, I am perfectly happy to help you attain that goal, and I’ll move on to the next candidate. And closely related to #2, perhaps we’ll call it #2.1 is this tip:  When I call you on the phone for the interview, don’t answer your phone by just saying, “Hello”.  You know that the odds are about 999-to-1 that it is me calling for the interview because we have specifically arranged this time slot for the call.  And you can see on the caller ID that it is not one of your buddies calling, so identify yourself.  Don’t make me question whether I dialed the right number.  Answer your phone with a, “Hello, this is ___<your full name preferred, but at least your first name>___.”.  And when I say, “Hi, <your name>, this is Mark from <my company>” it would be really nice to hear you say, “Hi, Mark, I have been expecting your call.”  This sets the perfect tone for our conversation.  I know I have the right person; you are professional enough and interested enough in the job or contract to remember your appointments; and now we can move on to a little intro segment and get on with the reason for our call. As crazy as it sounds, I’ve actually had phone interviews that went like this: <Ring…> You:  “Hello?” Me:  “Hi, this is Mark from _______” You:  “Yeah?” Me:  “Is this <your name>?” You:  “Yeah.” Me:  “I had this time in my calendar for us to talk…were you expecting my call?” You:  “Oh, yeah, sure…” I used to be nice and would try to go ahead with the interview even after this bad start, thinking I was giving the candidate the benefit of the doubt…a second chance…but more often than not it was a struggle and 10 minutes into what was supposed to be a 45-minute call, I’m looking for a way to hang up without being rude myself.  It never worked out.  I never brought that person in for an in-person interview, much less offered them the job or contract.  Who knows, maybe they were some sort of wunderkind that we missed out on.  What I know is that they would never fit in with the rest of the team, and around here that is absolutely critical. So, in conclusion… Act alive!  Identify yourself!  And do at least the very basic of research.

  • Multi-lingual error messages and error numbers

    - by Jon Hopkins
    So we're looking at the possibility of porting our software to support multiple languages and one of the areas we're going to have to deal with is error messages and other notifications. These obviously have to be reported to the users in their own language. Our team (largely) only speak English and even if we were all multi-lingual we're looking at selling to a wide range of countries and could never expect to have a reasonable number of people speaking all languages (we're a small company). The obvious way to get round the language issue when errors or other messages we may get asked about which are being reported is error numbers which would be consistent across language. While these are going to exist in the backend (if only as key on the error message), I'd really rather not throw them at users if we don't have to but I don't have any other solution. Anyone have any useful suggestions for alternatives?

  • Ideas for reducing storage needs and/or costs (lots of images)

    - by James P.
    Hi, I'm the webmaster for a small social network and have noticed that images uploaded by users are taking a big portion of the capacity available. These are mostly JPEGs. What solutions could I apply to reduce storage needs? Is there a way to reduce the size of images without affecting quality too much? Is there a service out there that could be used to store static files at a cheaper price (< 1GB/0.04 eurocents)? Edit: Updated the question.

  • Wireless not working, no driver showing in the Additional Drivers window

    - by edit lopez
    I am a new user of Ubuntu. I have a Asus Q501L laptop that came preinstalled with Windows 8, but I wanted to move from Windows and try something new, so I just decided to install Ubuntu without thinking to much about it. The problem I have is that I can't install the additional drivers. When I go to to Additional Drivers nothing appears, it just says: no proprietary drivers are in use and in small letters continues: a proprietary driver has private code that Ubuntu developers can't review and improve. security and others updates are dependent on drivers vendor.. I can't even use the wireless connection. I really don't know what to do. I tried to download the drivers from Asus, but when I tried to install them it said: an error occurred while loading the archive. Also I don't know the model of the PC wireless card. If there is something I can do to find out that please tell me. Thanks!

  • Opensource showcase for MVC in Java Swing

    - by Regular John
    I've allready created small desktop CRUD applications using Java/Swing. In hindsight I'm not quite sure if the overall design of these applications is good. I've also done some reading on MVC and looked at different Swing-tutorials. My problem is, that I've got a very theroatical knowledge of MVC and on the other hand, most Swing-resources don't implement the MVC-pattern. Now I would like to get my hands dirty and see how MVC is implemented in Swing in a real-world-application. Are there any opensource project you could recommend? It would be also interesting to have more than one project, to see different approaches. Best fit would be a software, that uses a relational database in the backend, to see an overall design, that I can compare to my former applications.

  • How to avoid Hotmail/Live rejections for (legit) large volume eMailing?

    - by vmarquez
    While qualifying eMail for Spam, Hotmail/Live checks the historical records of numbers of eMails sent by a sender (FROM, eMail Server, IP, etc.). Some times, perfectly valid bulk eMails that are not Spam, (i.e. double opt-in list, from a server with proper SPF Record, signed with DKIM, unregister links and contact info, etc.) are rejected and not delivered to destinataries. Not even to their Junk folder. I guess we can avoid this situation by progressivelly "training" Hotmail/Live about the reputation of our sender and sending small quantyties of eMails innitially and increasing the quantity for some amount/percentaje during each delivery. Are there guidelines or do you have any experience on these quantities, strategy, solutions? Thank you in advance. EDIT: This question with a bounty is still unanswered. 8 hours to be automatically awarded! Do you have the answer?

  • I prefer C/C++ over Unity and other tools: is it such a big downer for a game developer?

    - by jokoon
    We have a big game project using Unity at school. There are 12 of us working on it. My teacher seems to be convinced it's an important tool to teach students, since it makes students look from the high level to the lower level. I can understand his view, and I'm wondering: Is unity such an important engine in game development companies? Are there a lot of companies using it because they can't afford to use something else? He is talking like Unity is a big player in game making, but I only see it fit small indie game companies who want to do a game as fast as possible. Do you think Unity is of that much importance in the industry? Does it endanger the value of C++ skills? It's not that I don't like Unity, it's just that I don't learn anything with it, I prefer to achieve little steps with Ogre or SFML instead. Also, we also have C++ practice exercises, but those are just practice with theory, nothing much.

  • Artifacts when using SamplerState.LinearClamp in SpriteBatch

    - by Raymond Holmboe
    I'm using XNA 4.0 and VS2010 Express for Windows Phone and Windows Phone SDK 7.1. This is a platform game and I have a map made up of 16x16 textures that is drawn dynamically, tile by tile. When using SpriteBatch to draw my map with LinearClamp, I get artifacts that looks like blurry thin lines. They become visible when the camera moves from one pixel to another and when the camera is still, the artifacts disappear. Here's a small sample of what I mean: Here's how I draw with the spritebatch: SBWorld.Begin(SpriteSortMode.Deferred, BlendState.NonPremultiplied, SamplerState.LinearClamp, DepthStencilState.Default, RasterizerState.CullNone, null, camera.View); When using SamplerState.PointClamp the game just plays horribly (IMHO), so I cannot use that. Why do these lines appear and how do I get rid of those?

  • Transiltion from maintenance programing to design

    - by andrew wang
    What to do guys do develop a design for a s/w for a given set of requirements? I like many people joined a Semiconductor MNC and got stuck in maintenance for quite a couple of years. My work was usually changing a lines of code for windows drivers supplied by my company or a couple of small script (style like) C programs for validating h/w. As a result I developed the bad habit of 'programming by coincidence'. I have not developed the ability for designing tools/programs from scratch. I was the only s/w member of the local team and thus some grunt work from the well established other site of the company came to be done by me. Now I have moved to a different company and thus finding developing from scratch very difficult. How do I unlearn my bad habit and develop this ability of designing s/w and then coding it ?

  • Content theft - Where can I go from here?

    - by Toby
    I am the webmaster of a very successful blog in a fairly small niche. Recently our success has started to bite us with people copying posts on the site without consent and trying to pass them off as their own work. Most sites stop as soon as you contact them but there is one in particular that is a blogger site which persists in passing off our content as their own. Every post we find we report to Google and they have been fairly good at taking the posts offline within a day or two but this isn't good enough or a long term solution. Given the nature of what is being blogged about after 24 hours the post is pretty much useless so I need some way to just stop them from taking our content? Any ideas? I don't want to go down the route of using a third party for people to get our RSS feed but I guess that is one option?

  • Marketing texts for freelance programmers [closed]

    - by chiborg
    I'm a freelance developer and would like to set up a website that describes my services. When trying to come up with texts for the web site I got a severe case of writers block. I know that I'd like to describe what I do (websites, CMS, web-based applications), the different stages of projects (analysis, contract, prototype, testing, improvement, delivery, payment, etc) and who the target audience is (owners of small to medium businesses). But I have this feeling that there are some rules/tips on how to write such texts and I don't know them - any pointers?

  • What's the best way of marketing to programmers?

    - by Stuart
    Disclaimer up front - I'm definitely not going to include any links in here - this question isn't part of my marketing! I've had a few projects recently where the end product is something that developers will use. In the past I've been on the receiving end of all sorts of marketing - as a developer I've gotten no end of junk - 1000s of pens, tee-shirts and mouse pads; enough CDs to keep my desk tea-free; some very useful USB keys with some logos I no longer recognise; a small forest's worth of leaflets; a bulging spam folder full of ignored emails, etc... So that's my question - What are good ways to market to developers? And as an aside - are developers the wrong people to target? - since we so often don't have a purchasing budget anyways!

  • Customizing configuration with Dependency Injection

    - by mathieu
    I'm designing a small application infrastructure library, aiming to simplify development of ASP.NET MVC based applications. Main goal is to enforce convention over configuration. Hovewer, I still want to make some parts "configurable" by developpers. I'm leaning towards the following design: public interface IConfiguration { SomeType SomeValue; } // this one won't get registered in container protected class DefaultConfiguration : IConfiguration { public SomeType SomeValue { get { return SomeType.Default; } } } // declared inside 3rd party library, will get registered in container protected class CustomConfiguration : IConfiguration { public SomeType SomeValue { get { return SomeType.Custom; } } } And the "service" class : public class Service { private IConfiguration conf = new DefaultConfiguration(); // optional dependency, if found, will be set to CustomConfiguration by DI container public IConfiguration Conf { get { return conf; } set { conf = value; } } public void Configure() { DoSomethingWith( Conf ); } } There, the "configuration" part is clearly a dependency of the service class, but it this an "overuse" of DI ?

  • TTS on App Engine

    - by yati sagade
    I have written a small front-end to the Festival TTS system using Python/Django. I wish to deploy it on the Google App Engine cloud. A few questions: My application uses the Festival app 'text2wave'. Will is work on the cloud? I have used Python primitives like subprocess.call() to invoke the aforementioned program. Will that work? If your answer to any or both of (1) and (2) is no, is there a free api on the web that I can use (from the appengine)? I read somewhere about placing calls from Phono to a Voxeo backend, but I'm not sure what that means. I am aware of the Google Translate extension that allows translation using an HTTP GET (REST) request, but here the text is limited to 100 chars. Bad. Plus, they may take it down any point of time.

  • High level project workflow

    - by user775060
    We are a small software company trying our hand at our second game. Since our first games' process was a living nightmare (since we used webdevelopment workflow) I have decided to educate myself on how to manage a game project on a high level. How does your process work, from idea to launch? Preferably in situations where you have a team that needs to cooperate. I've seen these 2 links, which are useful in a way, but was wondering if there are better/more comprehensive ways to do this? http://www.goodcontroller.com/blog/?p=136 http://gogogic.wordpress.com/2009/02/09/symbol6-how-we-created-an-iphone-game/ All input would be infinitely appreciated.

  • New to Ubuntu - 12.04.1 Kernel Panic on Installation

    - by user88432
    I'm a complete Ubuntu and even Linux newbie. I'm learning here, so I'm grateful for any info to help me learn more about this. I have a Dell Dimension 2400 with a Pentium 4 and 1GB of RAM. It's older but it's only going to be doing some small stuff for me when I get it up and going. I've tried installing several versions of Linux (but I really, really want Ubuntu) and I keep getting a similar kernel panic message. The problem is I don't have a clue what that means or how to begin fixing it. I would appreciate any help to get my machine up and going. I have already tried Installing alternate Ubuntu versions Burning multiple 12.04.1 disks Installing other versions of Linux I have a picture of the screen to share; however, I can't post due to the fact that I don't have enough reputation points on this forum because I'm a newbie. I would be happy to email you a pic, if you think you can help.

  • My Red Gate Experience

    - by Colin Rothwell
    I’m Colin, and I’ve been an intern working with Mike in publishing on Simple-Talk and SQLServerCentral for the past ten weeks. I’ve mostly been working “behind the scenes”, making improvements to the spam filtering, along with various other small tweaks. When I arrived at Red Gate, one of the first things Mike asked me was what I wanted to get out of the internship. It wasn’t a question I’d given a great deal of thought to, but my immediate response was the same as almost anybody: to support my growing family. Well, ok, not quite that, but money was certainly a motivator, along with simply making sure that I didn’t get bored over the summer. Three months is a long time to fill, and many of my friends end up getting bored, or worse, knitting obsessively. With the arrogance which seems fairly common among Cambridge people, I wasn’t expecting to really learn much here! In my mind, the part of the year where I am at Uni is the part where I learn things, whilst Red Gate would be an opportunity to apply what I’d learnt. Thankfully, the opposite is true: I’ve learnt a lot during my time here, and there has been a definite positive impact on the way I write code. The first thing I’ve really learnt is that test-driven development is, in general, a sensible way of working. Before coming, I didn’t really get it: how could you test something you hadn’t yet written? It didn’t make sense! My problem was seeing a test as having to test all the behaviour of a given function. Writing tests which test the bare minimum possible and building them up is a really good way of crystallising the direction the code needs to grow in, and ensures you never attempt to write too much code at time. One really good experience of this was early on in my internship when Mike and I were working on the query used to list active authors: I’d written something which I thought would do the trick, but by starting again using TDD we grew something which revealed that there were several subtle mistakes in the query I’d written. I’ve also been awakened to the value of pair programming. Whilst I could sort of see the point before coming, I also thought that it was impossible that two people would ever get more done at the same computer than if they were working separately. I still think that this is true for projects with pieces that developers can easily work on independently, and with developers who both know the codebase, but I’ve found that pair programming can be really good for learning a code base, and for building up small projects to the point where you can start working on separate components, as well as solving particularly difficult problems. Later on in my internship, for my down tools week project, I was working on adding Python support to Glimpse. Another intern and I we pair programmed the entire project, using ping pong pair programming as much as possible. One bonus that this brought which I wasn’t expecting was that I found myself less prone to distraction: with someone else peering over my shoulder, I didn’t have the ever-present temptation to open gmail, or facebook, or yammer, or twitter, or hacker news, or reddit, and so on, and so forth. I’m quite proud of this project: I think it’s some of the best code I’ve written. I’ve also been really won over to the value of descriptive variables names. In my pre-Red Gate life, as a lone-ranger style cowboy programmer, I’d developed a tendency towards laziness in variable names, sometimes abbreviating or, worse, using acronyms. I’ve swiftly realised that this is a bad idea when working with a team: saving a few key strokes is inevitably not worth it when it comes to reading code again in the future. Longer names also mean you can do away with a majority of comments. I appreciate that if you’ve come up with an O(n*log n) algorithm for something which seemed O(n^2), you probably want to explain how it works, but explaining what a variable name means is a big no no: it’s so very easy to change the behaviour of the code, whilst forgetting about the comments. Whilst at Red Gate, I took the opportunity to attend a code retreat, which really helped me to solidify all the things I’d learnt. To be completely free of any existing code base really lets you focus on best practises and think about how you write code. If you get a chance to go on a similar event, I’d highly recommend it! Cycling to Red Gate, I’ve also become much better at fitting inner tubes: if you’re struggling to get the tube out, or re-fit the tire, letting a bit of air out usually helps. I’ve also become quite a bit better at foosball and will miss having a foosball table! I’d like to finish off by saying thank you to everyone at Red Gate for having me. I’ve really enjoyed working with, and learning from, the team that brings you this web site. If you meet any of them, buy them a drink!

  • Building a custom Xsession with VNC access

    - by Disco
    I have a small project where I'll need to build a very minimal X11 environnement for a cyber coffee kind shop. My idea is to have a simple server which will create a dozen of VNC Daemon listening on a different port (each port = one client). The server is working, i can connect using vnc to different port. Now i'm looking for a solution to create a customized desktop for each client; with a bare minimum of apps which i want to be able to add for each user. Like user1 will have app1 and app2, user2 will have app1 only etc. I plan to use openbox as a WM but no clue on 'how' to add custom icons on the desktop of it. Any clue, starting point would be interesting.

  • Swap and hibernation

    - by maaartinus
    I saw a lot of recommendations claiming that for hibernation the swap partition/file must be at least as large as the main memory. This makes no sense to me. Lets assume I have 8 GB of main memory and 8 GB swap area and want to hibernate: case 1: I'm using 4 GB of virtual memory - 8 GB of swap is unnecessarily large. case 2: I'm using 8 GB of virtual memory - 8 GB of swap is just right. case 3: I'm using 12 GB of virtual memory - 8 GB of swap is too small. The outcome is: A swap area of size equal to the memory size is sufficient for hibernate IFF it doesn't get used for swapping at all. So what is the reason behind the claim that you need at least as much swap area as main memory for hibernate to work? I know that virtual memory gets used for caching too, and that the cache may be simply discarded, but what happens to hibernation if a program allocates 12 GB of virtual memory (given the above memory and swap sizes)?
