  • Best way for a technical manager to stay up to date on technology

    - by JoelFan
    My manager asked for a list of technical blogs he should follow to stay current on technology. His problem is he keeps hearing terms that he hasn't heard of (i.e. NoSql, sharding, agure, sevice bus, etc.) and he would prefer to at least have a fighting chance of knowing something about them without having to be reactive and looking them up. Also I think he wants to have a big picture of all the emerging technologies and where they fit in together instead of just learning about each thing in isolation. He asked about blogs but I'm thinking print magazines may also help. What should I answer him?

  • Salaries in reverse engineering fields [closed]

    - by John
    I bumped into an old friend at a conference and he told me he was now a consultant doing reverse engineering. I don't have much knowledge of this particular area, but this person (that I can't manage to get in touch with now) just casually mentioned that he was earning big bucks. I was hoping someone at SO may know of the salary range that a skilled and experienced employee/freelancer may earn in this area? I can't find much information on the web - small area maybe? I dunno. Any help would be appreciated.

  • how to create 2D collision detection

    - by Aidan Mueller
    I would like to know the best or most effective way to test for 2D collision. I also can do AABBs but when you have a line, for example, that is rotated 45º, and it is really long. it will be hitting things when it shouldn't. I might be able to go through the pixels to see if they are touching others, but that might be slow if I had a big picture. and it might add some complications if I had a movie clip made of several images. How do I check collision between two Images? How would I do circle to box? Please help : ) PS: I do know java so you can write with java syntax and then use a made up GL

  • Managing Eclipse projects in source control

    - by Matt Phillips
    I've been using eclipse for a long time to do development. One of the problems I've come across when working on other people's projects is if they come from source control, some of the eclipse project files "default.properties" and other xml config files are missing. Its usually a big pain in the butt to get the project running in eclipse. I understand the reasoning to not have certain files tracked because they may be full of specific stuff to a certain eclipse install. How do all of you manage that?

  • What are the downsides to using dependency injection?

    - by kerry
    I recently came across an interesting question on stack overflow with some interesting reponses.  I like this post for three reasons. First, I am a big fan of dependency injection, it forces you to decouple your code, create cohesive interfaces, and should result in testable classes. Second, the author took the approach I usually do when trying to evaluate a technique or technology; suspend personal feelings and try to find some compelling arguments against it. Third, it proved that it is very difficult to come up with a compelling argument against dependency injection. What are the downsides to using dependency injection?

  • Remove gradients from elementary theme?

    - by John
    I really don't like the gradients in the elementary theme, and I was wondering if there were a way to remove them, from applications like Nautilus-Elementary, Postler, Dexter, etc. I've tried commenting out the Apps/[Application].rc in /usr/share/themes/elementary/gtk-2.0/gtkrc but it doesn't work, still leaves the gradients in their place. I'm a big fan of the other controls in the theme; the scroll bar, the way it borders gedit and the buttons, and I'd like to keep these features, but I don't like the way it styles its windows. Thanks for any help, as always!

  • 2D XNA Tile Based Lighting. Ideas and Methods

    - by Twitchy
    I am currently working on developing a 2D tile based game, similar to the game 'Terraria'. We have the base tile and chunk engine working and are now looking to implement lighting. Instead of the tile based lighting that terraria uses, I want to implement point lights for torches, etc. I have seen Catalin Zima’s shader based shadows, and this would be perfect for the torches (point lights). My problem here is that the tiles on the surface of the world need to be illuminated, doing this by a big point light is firstly extremely expensive, but also doesn't look right. What I need help with (overall) is... To have a surface that is illuminated regardless of torches, etc. To also have point lights, or smooth tile lighting similar to Catalin Zima’s shader based shadows. Looking forward to your replies. Any ideas are appreciated.

  • Is it worth being computer languages polyglot?

    - by Anton Barkowski
    You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn all relatively known programming languages. And here is question itself: Will being programming languages polyglot actually help you (And I don't mean usual "Programmer should know at least all paradigms", I mean really all languages you usually hear about)? Does anybody have similar experience? Does it help with job/skills/career? How often are you able to apply those skills?

  • What's the better user experience: Waiting once at startup for a long time or waiting frequently for a short time?

    - by Roflcoptr
    I'm currently design an application that involves a lot of calculation. Now I have generally two possibilities which I have both tested: 1) During startup of the application I calculated only the most important values and these values that consume a lot of time. So the user has to wait approximately 15 seconds during startup. But on the other hand a lot of user interactions require recalculation so that the user often has to wait 2-3 seconds after clicking somewhere until the application has calculated and loaded all values 2) I load everything during startup. This takes from 90 to 120 seconds... This is quite a long time, but the big advantage is that all the user interactions are executed immediately. So what would you generally consider the better approach? Loading all time-consuming operations during startup or when needed?

  • What happened to GremCheck? Is there a viable replacement?

    - by goober
    I was a big fan of an app called "GremCheck" that was out a while back, that seems to have disappeared. It was a JavaScript included in a master page that placed an icon at the bottom of the page. It was used during testing. You could define your own tests, and the box could pop up per page and viewers would answer the questions you define (such as "Does this page have the correct title?", "Is the Grammar Correct", "Does the design look consistent"). This was useful for end-user tests groups and quick testing for developers if time was squeezed on full functional testing. Anyone know where GremCheck went, if I can get to it, and if there's anything out there that does something similar?

  • When should I make the first commit to source control?

    - by Kendall Frey
    I'm never sure when a project is far enough along to first commit to source control. I tend to put off committing until the project is 'framework-complete' and primarily commit features from then on. (I haven't done any personal projects large enough to have a core framework too big for this.) I have a feeling this isn't best practice, though I'm not sure what all could go wrong. Let's say, for example, I have a project which consists of a single code file. It will take about 10 lines of boilerplate code, and 100 lines to get the project working with extremely basic functionality (1 or 2 features). Should I first check in: The empty file? The boilerplate code? The first features? At some other point? Also, what are the reasons to check in at a specific point?

  • What are the legal consequences of customizing the LiveCD?

    - by Voulnet
    Hello everyone, the organization I work at wants to create a custom Ubuntu LiveCD, the customizations are: Pre-installed programs, plugins, some device drivers, and aesthetics such as icons and backgrounds, as well as changing Firefox's homepage and removing unneeded packages. Not big changes, obviously, and we wish to distribute this custom image for clients to use as a bootable CD or USB stick in order to have a quick environment where all our tools are available instantly. What are the licensing and legal consequences of this? What if some of the programs or plugins that are to be pre-packaged are not GPL'd? I should finally note that we are not changing any code in the kernel or any other distro component. Thank you for your time!

  • Approach on working with many programmers on one module/feature

    - by Panoy
    How can 2 or more developers code a certain feature/module of a software? Let's assume that the module is big and feature rich. How would they prevent each other from overlapping their code? Say, we have the same method but is implemented in a different way. Do you think it might be better to have one focused at a specific feature only? Is a version control system like Git would help solve the problem? Is it correct that it allows developers to have these "branches" and then merge it later on? What's your take on this?

  • Must-do activities for a team leader, and time managing them

    - by MeLight
    This is a two part question Part one: I'm leading a small team of developers of mixed skills (juniors and seniors). I'm sometimes feeling that I focus too much on my own code, instead of seeing the big the picture, and managing the team. What would you say the most crucial non-coding activities for a team leader, related to his team members? Part two:Given that I know what other (non-coding stuff) I should be doing, what is a good time division between my own code writing and managing the other team members (code reviews, whiteboarding, meetings etc).

  • Generating an EJB SDO Service Interface for Oracle SOA Suite by Edwin Biemond

    - by JuergenKress
    In Oracle SOA Suite you can use the EJB adapter as a reference or service in your composite applications. The EJB adapter has a flexible binding integration, there are 3 ways for integrating the remote interface with your composite. First you have the java interface way which I described here this follows the JAX-WS way. It means you need to use Calendar for your Java date types and leads to one big WSDL when you add a wire to a service component. Read the full article here.

  • Avatar (spoiler alert!)

    - by Dave Yasko
    This past weekend we finally saw “Avatar,” or as I like to call it “Dances with Smurfs.”  It was rather light on the story, heavy on the message, and incredibly well done.  The eye for detail is what blew me away, especially the visual distortion (presumably due to density) when the two atmospheres mixed.  The only thing I thought they might have missed was why so many (presumably) mammals had 6 appendages (4 arms + 2 legs) and breathed through passages near their clavicles, but the Na’vi (sp?) didn’t have/do either.  Also, James Cameron just loves to telegraph upcoming events: Riding the big red bird thing has only happened 5 times before – Sully is on the job.  The tree is going to download dying Ripley to her avatar body – Sully is going to do that too.  I’ve seen worse foreshadowing, but not in a long time. I give it 4 Papa Smurfs out of 5.

  • Is eCPMs dropping by about 50% in January a usual behavior on Google AdSense?

    - by Andrew G. Johnson
    So I just got semi-serious about running some AdSense sites over the past 6 months and the eCPM's have hovered between 1.38 and 1.42 [yes it's that close] when I look at the eCPM for each month. Obviously some deviation day to day but pretty damn close to a buck forty in aggregate. So far for January I am sitting at 0.80 for an eCPM. I know it's not a huge sample size but the daily pageviews are fairly consistent [actually a bit higher] than where they were in December. I am trying to justify this by thinking that somehow a lot of ad buyers buy inventory for the year and have to get setup to do another big buy now that it's a new calendar year but that thought isn't close to comforting. Is this happening to anyone else? EDIT: I run a lot of websites and the ratios of pageviews are about the same this month to last month but just to be clear the eCPM I posted is for 20 websites in a variety of niches, it doesn't accurately depict any one domain.

  • Few specific questions on how games are developed

    - by russ
    When it comes to programming games from the old school sega games like sonic to indie games or angry birds or even to more advance games like Diablo, how exactly is level design done? As in, are the levels sometimes designed straight out of code in an IDE? Or do they create a visual level design editor where things can be placed at the click of a mouse button? I'm imagining old school games or very simple ones like indies are done via code, where extremely complicated ones require a visual editor. Is this correct? Also, when it comes to libraries like SDL or XNA, how often are these used rather than just utilizing OpenGL or DirectX? What about creating your own game engine vs utilizing one already made? Do most use already built engines? This question is directed toward the whole gaming spectrum of indie/big game development. Thanks.

  • Are there any companies using BDD in a .NET environment?

    - by Nick
    I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily. I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'. Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD. I have two questions really: Is BDD adopted by companies out there? Who are they? How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?

  • ZTE USB Modem AC2736, connection not possible in Ubuntu 12.04.1 LTS

    - by Fredo
    It's a long post but nearly covers all my experiments and changes I did to my NM. Hope the information is complete and if there are still question, more information can be provided. I've a ZTE AC2736 USB Modem (CDMA modem) which worked fine in Ubuntu 10.04 /11.10. I recently switched to 12.04.1 (precise pangolin). after the switch the first issue I faced was to connect to internet using my USB modem (ISP: Reliance Brand: Netconnect). Tried to run the drivers provided by Reliance but they are old and won't support Kernel 2.6.30 above. since the code was not downloaded with ISO image (of 12.04) i couldn't compile the files provided in such driver. lsusb does detect it as Modem with output similar to 19d2:fff1 ZTE CDMA technologies inc. (or similar as i didn't note it down) If it is detected as USB storage it shows 19d2:fff5 (as per few online forums, i may be wrong here). I used the network Manager and configured the modem to dial #777 (default) and the ISP provided username:password combination. It tries to connect to internet (3-4 times automatically)but fails to get online. once I was able to connect in the monring hours and the message was flashed 'registered on CDMA home network'. I was able to run an update. the kernel was updated with 3.0.2 -pae OR something similar (can find out if required). I surfed the net for about 2 hours later before restarting. After the restart, again the Modem was not able to get me online. I kept trying for many times. I tried changing the setting in NM. One evening after dark I was able to connect to network with same message flash 'registered on CDMA home network' (the message was similar, i'm not precise here,sorry). I was able to surf the net for nearly 3 hours before I switched off my Laptop. I'm not able to get online after that day, It's been 3 days now. I'll try the observered theory of late/early hours sometime soon as mentioned below. Laptop configuration : Make: Lenovo Model: B480 Processor: Intel B950 RAM: 4G DDR3 HDD: 500 G Broadcom Wireless/Bluetooth/Ethernet LAN OS: FreeDOS / Ubuntu 12.04 LTS (dualboot) Kernel 3.0.2-pae Obeservation : I'm able to connect to internet in those hours when generally the speed is high (low usage by other network (wireless) users). like in early mornings or late nights. This is strange as connection should not be dependent on bandwidth usage. Any help would be appraciated to fix this issue. before I decide to cahnge the OS or ISP.

  • A Community Cure for a String Splitting Headache

    - by Tony Davis
    A heartwarming tale of dogged perseverance and Community collaboration to solve some SQL Server string-related headaches. Michael J Swart posted a blog this week that had me smiling in recognition and agreement, describing how an inquisitive Developer or DBA deals with a problem. It's a three-step process, starting with discomfort and anxiety; a feeling that one doesn't know as much about one's chosen specialized subject as previously thought. It progresses through a phase of intense research and learning until finally one achieves breakthrough, blessed relief and renewed optimism. In this case, the discomfort was provoked by the mystery of massively high CPU when searching Unicode strings in SQL Server. Michael explored the problem via Stack Overflow, Google and Twitter #sqlhelp, finally leading to resolution and a blog post that shared what he learned. Perfect; except that sometimes you have to be prepared to share what you've learned so far, while still mired in the phase of nagging discomfort. A good recent example of this recently can be found on our own blogs. Despite being a loud advocate of the lightning fast T-SQL-based string splitting techniques, honed to near perfection over many years by Jeff Moden and others, Phil Factor retained a dogged conviction that, in theory, shredding element-based XML using XQuery ought to be even more efficient for splitting a string to create a table. After some careful testing, he found instead that the XML way performed and scaled miserably by comparison. Somewhat subdued, and with a nagging feeling that perhaps he was still missing "something", he posted his findings. What happened next was a joy to behold; the community jumped in to suggest subtle changes in approach, using an attribute-based rather than element-based XML list, and tweaking the XQuery shredding. The result was performance and scalability that surpassed all other techniques. I asked Phil how quickly he would have arrived at the real breakthrough on his own. His candid answer was "never". Both are great examples of the power of Community learning and the latter in particular the importance of being brave enough to parade one's ignorance. Perhaps Jeff Moden will accept the string-splitting gauntlet one more time. To quote the great man: you've just got to love this community! If you've an interesting tale to tell about being helped to a significant breakthrough for a problem by the community, I'd love to hear about it. Cheers, Tony.

EDIT: The gradients I'm talking about are the ones at the top of the window. Some examples: Nautilus-Elementary: Postler: Rhythmbbox: Transmission: I'd like to create a sort of matte look, similar to this, which was done using Orta: Nautilus-Elementary: Postler: Rhythmbox: Transmission: I'd like a flat color, preferably without the line separating the top part of the application with the bottom.

  • Breaking up the Workday– Overcoming the Workaholic Syndrome

    - by dwahlin
    Hi, my name’s Dan Wahlin and I’m a workaholic – I admit it. It’s good from the standpoint that I get a lot done but it also has a lot of cons associated with it as well that I’m not proud of. I literally can’t watch TV without feeling like I should be doing something more productive (although I have no problem going to see movies at a theater or watching sporting events – that’s my escape I guess). On vacation it’s sometimes difficult the first few days to just “let go” of work and enjoy the time with my family. I always feel like I should be checking email and following up with different business projects. Fortunately, my wife knows me really well after 17 years of marriage and “gently” restricts my usage of laptops and other gadgets while we’re out. She also reminds me that constantly burying my face in gadgets just isn’t cool and shows a distinct lack of self control. On a given day I typically put in between 12 (at a minimum) up to 16-18 hours working on projects. My company does .NET consulting (ASP.NET/jQuery, SharePoint and Silverlight) but we also do a lot in the training space so there’s always a client project, some new courseware or some other deliverable that has to be worked on. My normal process for handling that is to just work my butt off and see how much I can get done. That process has worked well for a long time but when you start realizing that your happiness comes from how much work you accomplished that day then you have a problem. That’s especially true if you have kids (which I do….two awesome boys). It’s almost as if working more hours feels like I’m more successful or something which is of course ridiculous. It may actually mean that I’m too distracted or disorganized. Lately I’ve realized that while I’m still productive and always meet my deadlines, I’m really burnt out by the afternoon and have lost some of the excitement I used to have. Part of that’s normal I think given that I’ve been doing this for close to 15 years now, but in thinking through it more I realized that I just need to get away from the desk and take a break. By far, the happiest time of my life was my childhood. Part of that was due to having awesome parents, having far less responsibility (a big factor I suspect), being able to hang-out with friends at school, playing sports, games, etc. but I think a big part of the overall happiness came from being outside a lot. I lived on my bike as a little kid and as I grew up I shared time between riding an ATV all over the place, shooting hoops on the basketball court, playing golf and working on a golf course (all outside work of course).  Being a software developer and trainer I generally spend 95% or more of my day indoors and only see the sun when driving from place to place or by looking out the window (that’s sad because I live in a suburb of Phoenix, AZ where it’s nearly always sunny). I haven’t looked into any scientific studies on the matter, but I’d be willing to bet there’s a direct correlation between overall productivity/happiness and being outside some throughout the day (sunny or not). But, I wasn’t sure what to do about it since I do have a lot of deadlines I need to meet after all. While talking with my wife last night I mentioned how I feel like I’m in a rut and want to get the “fun” back that I used to have. She immediately said that I need to start making time for breaks (a real quick fact – she’s a lot smarter than me and nearly always right). Of course my first thought was that I’d be less productive taking breaks. If I spend 2 hours just relaxing then I’m losing 2 hours of work. But, I thought about it more and realized that I’m probably less productive when I work 10+ hours and only take less than 30 minutes for a lunch break to relax a little. I bet my brain is screaming, “Please let me relax a little so I can figure out these problems you’re trying to resolve!”. So, starting today I’m going to try to break the workaholic habit and spend time outside of the office. That could mean sitting around outside, working out, golfing, or whatever. I’ve decided that no gadgets are allowed during that time and that I shouldn’t work for more than 4 hours straight without taking a break. I have no idea how my little “break the workaholic syndrome” experiment will go or how long it will last, but I’d be very interested in hearing from others on how they keep fresh and focused without working yourself to death. If you have any specific ideas, techniques or practices you follow please share them. There’s a lot more to life than work and some of us (and I’m thinking of myself specifically) need to take a long, hard look at what kind of balance we currently have. I’d hate to look back at my life when I’m 80 years old and say, “The only thing I did was work – I missed out on life!”.
