  • 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.

  • How can one manage thousands of IF...THEN...ELSE rules?

    - by David
    I am considering building an application, which, at its core, would consist of thousands of if...then...else statements. The purpose of the application is to be able to predict how cows move around in any landscape. They are affected by things like the sun, wind, food source, sudden events etc. How can such an application be managed? I imagine that after a few hundred IF-statements, it would be as good as unpredictable how the program would react and debugging what lead to a certain reaction would mean that one would have to traverse the whole IF-statement tree every time. I have read a bit about rules engines, but I do not see how they would get around this complexity.

  • Is software innovation still primarily North American and European? Why, and for how much longer?

    - by limist
    Since this site is read by a global audience of programmers, I want to know if people generally agree that the vast majority of software innovation - languages, OS, tools, methodologies, books, etc. - still originates from the USA, Canada, and the EU. I can think of a few exceptions, e.g. Nginx webserver from Russia and the Ruby language from Japan, but overwhelmingly, the software I use and encounter daily is from North America and the EU. Why? Is history and historical momentum (computing having started in USA and Europe) still driving the industry? And/or, is some nebulous (or real) cultural difference discouraging software innovation abroad? Or are those of us in the West simply ignorant of real software innovation going on in Asia, South America, Eastern Europe, etc.? When, if ever, might the centers of innovation move out of the West? Your experiences and opinions welcome, thanks!

  • Getting work done in a small office

    - by three-cups
    I work in an office area of ~450sqft. There are a total of 7 people working in the office. I've been finding it hard to concentrate on my work (writing code) because of the distractions going on around me. The distractions are both work-related and non-work-related conversations. I'm trying to figure out what to do in this situation. I want to be part of the team, and I want to get my work done to the best of my ability. I can easily think of two options that I don't like: Stay where I am, not be able to concentrate and get less work done Move somewhere else. (This is tough because I code on a desktop, so I'm not very mobile.) But what are other options? I'm going to talk this through with my team in the next couple days. Any advice or solutions would be great.

  • Reassign the Right button functionality of touchpad

    - by Guandalino
    My notebook has a touchpad with two buttons. The touchpad works pretty well and I use it for vertical/horizontal scroll, two fingers scrolling etc. The Left button acts like the left button of a mouse. The Right button too, when clicked it makes appear the classic contextual menu (create new folder, move to trash etc...). The problem is that Right button doesn't work anymore for mechanical reasons, so pressing it has no effect. To recover the missing functionality, I'd like that pressing CTRL + Left button I get the same thing of pressing the Right button alone. Other combinations (CTRL + SHIFT + Left button) are also acceptable. Any way to do that?

  • Which paradigm to use for writing chess engine?

    - by poke
    If you were going to write a chess game engine, what programming paradigm would you use (OOP, procedural, etc) and why whould you choose it ? By chess engine, I mean the portion of a program that evaluates the current board and decides the computer's next move. I'm asking because I thought it might be fun to write a chess engine. Then it occured to me that I could use it as a project for learning functional programming. Then it occured to me that some problems aren't well suited to the functional paradigm. Then it occured to me that this might be good discussion fodder.

  • rts libgdx design?

    - by user36531
    I am attempting to create a simple rts multi-player strategy game using libgdx. I am stumped at the moment. I want the underlying game world to run at all times and be aware of where all items are on the map.. so if player A logs in and moves unit to some location on the grid and logs off, that unit info is still there and can be accessed again by player A when they log back on to move somewhere else (if it didnt get attacked during the playerA was logged off). How can i do this? Do i create a main game world on the server and when players connect make client just sequentially request whats in each visible tile? Is there an easier way to get this done? Or go SQL route? Whats better?

  • All day optimizer event....

    - by noreply(at)blogger.com (Thomas Kyte)
    I've recently taken over some of the responsibilities of Maria Colgan (also known as the "optimizer lady") so she can move onto supporting our new In Memory Database features (note her new twitter handle for that: https://twitter.com/db_inmemory ).To that end, I have two one day Optimizer classes scheduled this year (and more to follow next year!).  The first one will be Wednesday November 20th in Northern California.  You can find details for that here: http://www.nocoug.org/ .The next one will be 5,500 miles (about 8,800 km) away in the UK - in Manchester.  That'll take place immediately following the UKOUG technical conference taking place the first week of December on December 5th.  You can see all of the details for that here: http://www.ukoug.org/events/tom-kyte-seminar-2013/I know I'll be doing one in Belgrade early next year, probably the first week in April. Stay tuned for details on that and for more to come.

    If you get a lot of forwards from well meaning relatives and want to instantly and effortlessly verify their content, LazyTruth is a Chrome extension that fact-checks forwarded emails in Gmail. It’s a rather novel concept: install LazyTruth and anytime you get a forwarded email you’re one click away from instant fact checking. LazyTruth checks keywords in the email against FactCheck.org and Politifiact (Snopes.com missing seems like a big oversight, hopefully they’ll be adding it soon).

  • Rotation based on x coordinate and x velocity?

    - by Lewis
    -(void) accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration { float deceleration = 0.3f, sensitivity = 8.0f, maxVelocity = 150; // adjust velocity based on current accelerometer acceleration playerVelocity.x = playerVelocity.x * deceleration + acceleration.x * sensitivity; // we must limit the maximum velocity of the player sprite, in both directions (positive & negative values) playerVelocity.x = fmaxf(fminf(playerVelocity.x, maxVelocity), -maxVelocity); } Hi, I want to rotate my sprite based on the velocity and accelerometer input. My sprite can move along the X axis like so: <--------- sprite ----------- But it always faces forwards, if it is moving left I want it to point slightly to the left, the degree of how far it is pointing to be judged from the velocity. This should also work for the right. I tried using atan but as the y velocity and position is always the same the function returns 0, which doesn't rotate it at all. Any ideas? Regards, Lewis.

  • Why do meshes show up as bones in the Model class?

    - by Itamar Marom
    Right now I'm working on a 3D game and I've come across something very weird. When I created the model in Blender, I added an armature named "MyBone" to the stage and attached a cube ("MyCube") to it, so that when I move the armature, the cube moves with it. I exported this as an FBX and loaded it as a Model object. What I expected to see was: But what I got was this: I'm really confused. Why is the mesh I created showing up in the bone list? And what's Root Node? Here are the .blend and .fbx files: here or here. Thanks.

  • How to reset settings when Unity won't finish booting?

    - by Emre
    I have a new 12.04 installation and I messed things up after trying to move /home to an NTFS partition, which I later learned was a bad idea. I removed references to the NTFS partition on fstab and created new users on the ext4 / partition. Now I can't get Unity to start up properly for any user. I get the GUI with only three Launch icons (none of which are clickable) and no bar at the top. The keyboard seems to the nonfunctional after I enter my credentials. The interesting thing is that I can boot when I go through recovery mode and select resume. I wonder whether I am creating the new users properly. What is the correct protocol for doing so in order to ensure that they can run Unity?

  • There is any reason for which a delete method/field/function refactoring doesn't exist?

    - by raisercostin
    An operation in an interface is obsolete so I decided to delete it. It seems that there is no automatic support for such a "refactoring". For me is a refactoring operation since the behavior of the code will be preserved since nobody(tests, client apis) will notice that the operation was removed. In eclipse, in java code, on an method in an interface I have the following options: rename, move, change method signature, inline, extract interface, extract superclass, use supertype when possible, pull up, push down, introduce parameter objet, introduce indirection, generate declared type. There is any reason for which a delete method/field/function refactoring doesn't exist?

  • Dynamic vs Statically typed languages for websites

    - by Bradford
    Wanted to hear what others thought about this statement: I’ll contrast that with building a website. When rendering web pages, often you have very many components interacting on a web page. You have buttons over here and little widgets over there and there are dozens of them on a webpage, as well as possibly dozens or hundreds of web pages on your website that are all dynamic. With a system with a really large surface area like that, using a statically typed language is actually quite inflexible. I would find it painful probably to program in Scala and render a web page with it, when I want to interactively push around buttons and what-not. If the whole system has to be coherent, like the whole system has to type check just to be able to move a button around, I think that can be really inflexible.

  • How can I host a website on a dynamically-assigned IP address?

    - by nick
    I recently upgraded my internet to the point that it is much faster and more reliable than my current webhost. I would like to move my current domain to be hosted at home, but my IP address is dynamic. As far as I know, I only get a new IP when I restart my modem and or router (which is almost never) or when cable one (my ISP) pushes out a firmware update (rarely). There are a few ways I can see doing this: Convince my ISP to give me a static IP Assign my router my current IP to force a static IP (which might work?) Set my DNS record to my current IP address and update it on the rare occasions that it changes. Obviously I'm hoping that the first one works, but I don't want to pay a lot of extra money (if that's what it takes) to get a static IP address. Which of these options will work most reliably?

  • Enabling Multi-touch features of the Apple Magic Mouse on Ubuntu 12.04

    - by Martin
    I want to write a simple app that uses Apple's Magic Trackpad, nothing special, just so that it recognizes atleast one gesture. The thing is, Ubuntu itself doesnt really recognize this device. I'm using Ubuntu 12.04 and by default the device works with 1 finger, but without tap-click or doubletap, 3 fingers move the window and 3 finger spread makes it fullscreen. I managed to enable 2 finger scrolling with "xinput set-prop 8 'Two-Finger Scrolling' 1 1", but thats about it. No other gestures work, ginn doesnt start, giesview detects the device but doesnt respond to any of the gestures, and touchegg doesnt start either. I tried example apps from qt that come with ubuntu but they dont work. So... what do i do? i tried using qt but all i get from the app is "Got touch without getting TouchBegin for id XX" what else can i use to get my app to work with multitouch devices?

  • Setting Anchor Point

    - by Siddharth
    I want to set anchor point for the sprite like cocos2d has done for their implementation. I do not found any thing like that in andengine so please provide guidance on that. I want to move the sprite on touch so I use following code but that does not work for me. super.setPosition(pX - this.getWidthScaled() / 2, pY - this.getHeightScaled() / 2); Because I touch on the corner of the image but automatically it comes at center of the image because of above code. I want to remain the touch at desire position and drag it. For me the anchor point became useful. But I don't found anything in andengine.

  • No Window Options in Cairo Dock

    - by Blind Fish
    I'm not even sure how to describe this properly. I'm running Cairo Dock on Ubuntu 12.04 LTS and I've noticed that I no longer have the top bar of my windows. I mean, I have the bar itself, but it's empty aside from the name of the window and the close / resize boxes. For instance, a simple Nautilus window would have, when you move the cursor to the top bar, a list of options such as View / Edit etc. I have nothing like that for any window or application. It's just solid black. This is a huge problem and I'm not sure what the issue is. Has anyone else experienced this?

  • Tempescope Displays Weather by Recreating It

    - by Jason Fitzpatrick
    Yesterday we showed you an umbrella stand that signals raining/clear skies by color, today we have something even more interesting: an ambient desktop weather station that recreates the outside weather. The Tempescope pulls down the current weather report from Weather Underground’s API and feeds it to an Arduino board which in turn controls the device. When it’s raining, it pumps water down to simulate rain in the chamber. When there is lightening, LEDs flash. When there is cloud cover, an ultrasonic generator creates a fine mist inside the cylinder. Finally, on sunny days the entire thing glows warmly. To say that we want one would be an understatement. Hit up the link below to read more about the project, the display modes, and to peek inside the device.

  • 3 Trends for SMBs around Social, Mobile, and Sensor

    - by Socially_Aware_Enterprise
    While I often am talking to big companies or discussing enterprise solutions. There are times when individuals ask me about Small or Medium sized business trends.  Interestingly,  the Enterprise Social, Mobile, and Sensor initiatives I regularly discuss are in fact related to even the Mom and Pop storefront. The eco-system of new service players in the Social-Mobile-Sensor space generally emerge developing partnerships with enterprises as they develop and bring economy to scale to their services for the larger market. And of course Oracle has an entire division dedicated for delivering products and support to help emerging companies compete without the need to open an industrial strength credit line.. So here are some trends that we are helping large enterprises to deploy today, but small and medium businesses should be able to take advantage of by the end of this year and starting into 2015. 1) The typical small business is generally "Localized". But the ability to be "Hyper-Localized" will come as location based services become ubiquitous. Many small businesses have one or several storefronts and theirs are typically within a single regional economic footprint. While the internet provides global reach, it will be the businesses that invest in social, mobile and local that will win in the end.  Of course I am a huge SoMoLo evangelist. The SMBs' content and targeting with platforms for Geo-Fencing, Geo-Conquesting and Path-Matching to HHI are all going to be accessible to them, if not for Mobile Apps, then via Mobile messaging in Social Networks that offer it.. Expect to be able to target FaceBook messaging not by city, but by store or mall… This makes being able to be "Hyper-Local" even more important. And with new proximity services coming online more than ever before, SMBs will operate and service customers with pinpoint accuracy right down to where they stand in an aisle. Geo-Conquesting will be huge for small players to place ads when customers pass through competitors regions. Car Dealers are doing this now.. But also of course iBeacons are now very cheap and getting easier to put in retail stores. The ability for sales to happen anywhere in the store via a mobile phone or tablet is huge, as it will give the small shop the flexibility to not have to "Guard the Register" as more or most transactions will be digital. Thus, M-Commerce and T-Commerce will change the job of cashier dramatically.. 2) Intra-Brand Advocacy, the idea now is that rather than just depend on your trusty social media manager and his team, you are going to push more and more individuals with expertise inside the organization to help manage, reach-out, and utilize social channels to manage the incoming questions and answers customers need. While for years CRM was the tool of the enterprise, today CRMs enable this now "Salesforce et al" capability to trickle throughout the company. This gives greater pressure to organize roles, but also flatten out the organization. Internal collaboration around topics and customer needs is going to be the key for SMBs to finally get serious about customer experiences. Their customers are online and in social networks. This includes not just B2C SMBs but also B2B companies as well. Don't believe me? To find the players just use hashtag #SocialSelling and you will see… 3) The Visual Networks will begin to move from Content Aggregators to Content Collaboration platforms, which means Pinterest, Instagram, Vine, & others will begin to move to add more features brands want, first marketing platforms, rather than unique brand partnerships as they do today, but this will open ways for SMBs to engage with clear brand messaging and metrics. Eventually providing more "Collaboration" between Brand and Consumer.. Don't think for a minute Facebook bought Oculus Rift so you could see your timeline in 3-D. The Social Networks I advise customers to invest in are ones that are audio and visual intrinsically. Players from SoundCloud to Pinterest are deploying ways for brands to harness their interactive visual or audio based social networks to sell ad units aka brand messaging. While the Social Media revolution is going on, the emphasis was on the social, today it more and more about the media in social, that enterprises soon small and medium businesses will be connected to.
