  • How to integrate technical line/functional manager into Scrum team?

    - by thegreendroid
    We have recently had a new line manager start who is managing our Scrum team. He is immensely experienced in our field but is relatively inexperienced at Agile/Scrum. He has extensive technical expertise in embedded software (the team's domain) that would go to waste if not utilised properly. However, the team is wary of making a line manager part of the Scrum team. The general consensus is that the line manager should not be part of the Scrum team at all. There are a number of issues that may crop up, e.g. the team may start "reporting" to the manager (i.e. a daily status update!), the manager may start to micro-manage team members etc etc. As it currently stands, he has already said that he feels like an outsider within the team. We really want to make use of his technical skills, we'd be foolish if we didn't because we are a relatively inexperienced and young team of twenty somethings. What would be the best approach to integrate a senior "technical" line manager in a Scrum team and make him feel like he is part of the team?

  • How to go from Mainframe to the Cloud?

    - by Ruma Sanyal
    Running applications on IBM mainframes is expensive, complex, and hinders IT responsiveness. The high costs from frequent forced upgrades, long integration cycles, and complex operations infrastructures can only be alleviated by migrating away from a mainframe environment.  Further, data centers are planning for cloud enablement pinned on principles of operating at significantly lower cost, very low upfront investment, operating on commodity hardware and open, standards based systems, and decoupling of hardware, infrastructure software, and business applications. These operating principles are in direct contrast with the principles of operating businesses on mainframes. By utilizing technologies such as Oracle Tuxedo, Oracle Coherence, and Oracle GoldenGate, businesses are able to quickly and safely migrate away from their IBM mainframe environments. Further, running Oracle Tuxedo and Oracle Coherence on Oracle Exalogic, the first and only integrated cloud machine on the market, Oracle customers can not only run their applications on standards-based open systems, significantly cutting their time to market and costs, they can start their journey of cloud enabling their mainframe applications. Oracle Tuxedo re-hosting tools and techniques can provide automated migration coverage for more than 95% of mainframe application assets, at a fraction of the cost Oracle GoldenGate can migrate data from mainframe systems to open systems, eliminating risks associated with the data migration Oracle Coherence hosts transactional data in memory providing mainframe-like data performance and linear scalability Running Oracle software on top of Oracle Exalogic empowers customers to start their journey of cloud enabling their mainframe applications Join us in a series of events across the globe where you you'll learn how you can build your enterprise cloud and add tremendous value to your business. In addition, meet with Oracle experts and your peers to discuss best practices and see how successful organizations are lowering total cost of ownership and achieving rapid returns by moving to the cloud.

  • Can't connect to or see my wifi ssid

    - by ant
    Today I installed ubuntu 12.04 on my laptop. I am unable to see my home SSID or even connect to it. I've tried to connect as a hidden SSID but I always get prompted for authorization although my key is correct. I'm in in Europe but my laptop is from US. I'm not sure if that is relevant. I've read around this site and saw something that has to do with setting the channel above 11. I'm not sure I did that correctly I did this : How to use Wi-Fi channels above 11? Did't help. I'm able to connect with cable but not via wifi either windows or linux. Other devices in my home can connect without any issues, even the kindle. Here is the screenshot from my router : Here is some additional info : lspci | grep -i network 08:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) lspci -nnk | grep -A2 0280 08:00.0 Network controller [0280]: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01) Subsystem: Hewlett-Packard Company U98Z062.10 802.11bgn Wireless Half-size Mini PCIe Card [103c:303f] Kernel driver in use: ath9k m-tool NetworkManager Tool State: connected (global) Device: wlan0 ---------------------------------------------------------------- Type: 802.11 WiFi Driver: ath9k State: disconnected Default: no HW Address: 90:4C:E5:38:79:0D Capabilities: Wireless Properties WEP Encryption: yes WPA Encryption: yes WPA2 Encryption: yes I'm not sure what to do next.

  • How to tell your boss that his programming style is really bad?

    - by Roflcoptr
    I'm a student and in my spare time I'm working for a big enterprise as Java developer. The job is good, but the problem is, my boss is writing very strange code. I don't want to complain, but some issues are in my opinion really strange. For example: he doesn't know any booleans. All boolean conditions are Strings called "YesOrNo" and then in the condition he uses if (YesOrNo == "Yes") there are a lot of very strange characters in method names and variables like é õ ô or è all loops are infinite loops in the style of for(;;). Then at the end of the loop the condition is tested and if the conditions is fulfilled break; is called. I don't now if I should tell him that I think this isn't a good practice, since he is my boss and decides how and what to do. On the other hand some of this examples are really very weird. Any hints how to cope with? And is this only me who thinks that's bad style?

  • Strategies for managUse of types in Python

    - by dave
    I'm a long time programmer in C# but have been coding in Python for the past year. One of the big hurdles for me was the lack of type definitions for variables and parameters. Whereas I totally get the idea of duck typing, I do find it frustrating that I can't tell the type of a variable just by looking at it. This is an issue when you look at someone else's code where they've used ambiguous names for method parameters (see edit below). In a few cases, I've added asserts to ensure parameters comply with an expected type but this goes against the whole duck typing thing. On some methods, I'll document the expected type of parameters (eg: list of user objects), but even this seems to go against the idea of just using an object and let the runtime deal with exceptions. What strategies do you use to avoid typing problems in Python? Edit: Example of the parameter naming issues: If our code base we have a task object (ORM object) and a task_obj object (higher level object that embeds a task). Needless to say, many methods accept a parameter named 'task'. The method might expect a task or a task_obj or some other construct such as a dictionary of task properties - it is not clear. It is them up to be to look at how that parameter is used in order to work out what the method expects.

  • Session serialization in JavaEE environment

    - by Ionut
    Please consider the following scenario: We are working on a JavaEE project for which the scalability starts to become an issue. Up until now, we were able to scale up but this is no longer an option. Therefore we need to consider scaling out and preparing the App for a clustered environment. Our main concern right now is serializing the user sessions. Sadly, we did not consider from the beginning the issue and we are encountering the following excetion: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: org.apache.catalina.session.StandardSessionFacade I did some research and this exception is thrown because there are objects stored on the session which does not implement the Serializable interface. Considering that all over the app there are quite a few custom objects which are stored on the session without implementing this interface, it would require a lot of tedious work and dedication to fix all these classes declaration. We will fix all this declarations but the main concern is that, in the future, there may be a developer which will add a non Serializable object on the session and break the session serialization & replication over multiple nodes. As a quick overview of the project, we are developing using a home grown framework based on Struts 1 with the Servlet 3.0 API. This means that at this point, we are using the standard session.getAttribute() and session.setAttribute() to work with the session and the session handling is scattered all over the code base. Besides updating the classes of the objects stored on session and making sure that they implement the Serializable interface, what other measures of precaution should we take in order to ensure a reliable Session replication capability on the Application layer? I know it is a little bit late to consider this but what would be the best practice in this case? Furthermore, are there any other issues we should consider regarding this transition? Thank you in advance!

  • Fun Upgrading to .Net 4.0

    - by Sam Abraham
    We are currently in the process of upgrading one of our applications to .Net 4.0. Aside from us geeks wanting to always use latest and greatest technologies, an immediate business need for Silverlight 4.0 features justified our upgrade endeavor. The following is a summary of some issues we ran into with our web project:   For security purposes, the IIS 7 .Net 4.0 ISAPI filter is disabled. “Allow” it from the ISAPI and CGI Restrictions screen as shown:   Figure 1 - Allowing ASP.Net 4.0 ISAPI Filter   By default the Web Setup Project only requires the .Net Framework 4 Client Profile to be installed on target system, which offers a lighter weight install for client machines consuming .Net 4.0 applications. However, using certain .Net 4.0 features requires the full .Net 4.0 Framework as outlined in this link: http://msdn.microsoft.com/en-us/library/cc656912.aspx. We hence needed to update the installer to require the complete .Net 4.0 Framework on the target machine and to prompt for its installation if needed.   To accomplish this goal, we updated the installer’s launch conditions to check for .Net 4.0 as well as the installer prerequisites as shown:     Figure 2- Ensure Web Setup Project runs on full .Net 4.0 version Figure 3 - Launch Conditions screen Figure 4 - Set launch condition to .Net 4.0.

  • Why doesn't my IDE do background compiling/building?

    - by MKO
    Today I develop on a fairly complex computer, it has multiple cores, SSD drives and what not. Still, most of the time I'm programming the computer is leasurely doing nothing. When I need to compile and run/deploy a somewhat complex project at best it still takes a couple of seconds. Why? Now that we're living more and more in the "age of instant" why can't I press F5 in Visual studio and launch/deploy my application instantly? A couple of seconds might not sound so bad but it's still cognitive friction and time that adds up, and frankly it makes programming less fun. So how could compilation be instant? Well, People tend to edit files in different assemblies, what if Visual Studio/The IDE constantly did compilation/and building of everything that I modified anytime that it might be appropriate. Heck if they wanted to go really advanced they could do per-class compilation. The compilation might not work but then it could just silently do nothing (except adding error messages to the error window). Surely todays computer could dedicate a core or two to this task, and if someone found it annoying it could be disabled by option. I know there's probably a thousand technical issues and some fancy shadow copying that would need to be resolved for this to be seamless and practical but it sure would make programming more seamless. Is there any practical reason why this scenario isn't possible? Would the wear and tear of continually writing binaries be too much? Couldn't assemblies be held in memory until deployed/run?

  • CloudMail

    - by kaleidoscope
    In Web Applications, we often come across requirement of sending and receiving emails through our application. So same can be for the applications hosted on Azure. So Do you want to send email from an application hosted on Azure? CloudMail is one of the possible answers. CloudMail is designed to provide a small, effective and reliable solution for sending email from the Azure platform directly addressing several problems that application developers face. Microsoft does not provide an SMTP Gateway (yet) so the application is forced to connect directly to one hosted somewhere else, on another network. So to implement such functionality one of the possible option is using Free email providers. This might be fine for testing, but do you really want to rely on a free service in production? There can be other issues with this approach like if your chosen SMTP gateway is down or there are connection problems? Again there can be some specific requirement that, you want to send email via a company’s mail server, from inside their firewall. CloudMail solves these problems by providing a small client library that you can use in your solution to send emails from you application and a Windows Service that you run inside your companies network that acts as a relay. Because the send and relay are disconnected there are no lost emails and you can send from your own SMTP Gateway.   CloudMail is in its Beta version and available for download here.   Technorati Tags: Geeta,Azure Email,CloudMail

  • SQL SERVER – Caption the Cartoon Contest – Last 2 Days

    - by pinaldave
    Developer’s life is very interesting, we often want to start my day early at a job so we can go home early. However, the day never comes as the life of the developer is always about working late hours. If the developer goes to the office early – there are good chances that his co-workers will come late. Additionally, I am confident that there will be always something urgent for developers or DBA to solve right at the time they are ready to go home. This is the life of the developers!  Here is the interesting story of a DBA who was about to go to the home. He had to take his girlfriend to a movie and dinner in 30 minutes. However, his manager asks him to fix the performance related issues with their production server. In normal case, he had only two choices a) Job or b) Girlfriend. Well, our super hero DBA decided to use efficient tools and improve the performance of the production server in merely 30 minutes. When he was done, his manager was absolutely surprised by his efficiency and accuracy of the work. He asked him following question - Here is the contest – you need to guess what was the answer of our Super Hero DBA. If you guess the answer correct you may win Star Wars R2-D2 Inflatable Remote Controlled device. Additionally, if you Download DB Optimizer before Dec 8, 2012 – you will be eligible for USD 25 Amazon Gift Card (there are total 10 such awards).

  • Museum of Modern Art Starts Video Game Collection; Acquires Myst, Pac-Man, and More

    - by Jason Fitzpatrick
    The Museum of Modern Art is weighing in on the video-games-as-art debate by starting a collection of iconic video games and putting them up for public display. Read on to see what games are included in the initial batch and the MoMA’s reasons behind starting a video game collection. Although the MoMA is slated to grow to over 40 titles, the seed batch is 14 titles including: Pac-Man, Tetris, Sim City 2000, Myst, Portal, and Dwarf Fortress. In the announcement they explain the motivation for building a video game collection: Are video games art? They sure are, but they are also design, and a design approach is what we chose for this new foray into this universe. The games are selected as outstanding examples of interaction design—a field that MoMA has already explored and collected extensively, and one of the most important and oft-discussed expressions of contemporary design creativity. Our criteria, therefore, emphasize not only the visual quality and aesthetic experience of each game, but also the many other aspects—from the elegance of the code to the design of the player’s behavior—that pertain to interaction design. In order to develop an even stronger curatorial stance, over the past year and a half we have sought the advice of scholars, digital conservation and legal experts, historians, and critics, all of whom helped us refine not only the criteria and the wish list, but also the issues of acquisition, display, and conservation of digital artifacts that are made even more complex by the games’ interactive nature. This acquisition allows the Museum to study, preserve, and exhibit video games as part of its Architecture and Design collection. The above quote is only a small snippet of a much lengthier look at the benefits of examining and preserving video games, hit up the link below to check out the full post including future titles the MoMA would like to include in their archive.

  • Good 2D Platformer Physics

    - by Joe Wreschnig
    I have a basic character controller set up for a 2D platformer with Box2D, and I'm starting to tweak it to try to make it feel good. Physics engines have a lot of knobs to tweak, and it's not clear to me, writing with a physics engine for the first time, which ones I should use. Should jumping apply a force for several ticks? An impulse? Directly set velocity? How do I stop the avatar from sticking to walls without taking away all its friction (or do I take away all the friction, but only in the air)? Should I model the character as a capsule? A box with rounded corners? A box with two wheels? Just one big wheel? I feel like someone must have done this before! There seem to be very few resources available on the web that are not "baby's first physics", which all cut off where I'm hoping someone has already solved the issues. Most examples of physics engines for platformers have floaty-feeling controls, or in-air jumps, or easily exploitable behavior when temporary penetration is too high, etc. Some examples of what I mean: A short tap of jump jumps a short distance; a long tap jumps higher. Short skidding when stopping or reversing directions at high velocity. Standing stably on inclines (but maybe sliding down them when ducking). Analog speed when using an analog controller. All the other things that separate good platformers from bad platformers. Dare I suggest, stable moving platforms? I'm not really looking for "hey, do this." Obviously, the right thing to do is dependent on what I want in the game. But I'm hoping someone somewhere has gone through the possibilities and said "well technique A does feature X well, technique B does Y well, but that doesn't work with C", or has some worked examples beyond "if (key == space) character.impulse(0, 1)"

  • AMD FX CPU drivers/patch

    - by Mubeen Shahid
    I am using Ubuntu since 2009 on notebooks with Intel CPUs. However now, that I am using AMD's FX 6300, I am interested in knowing if there exists anything from Ubuntu (specifically any kernel enhancements/drivers/patches) for AMD's FX "family 15h" Piledrivers. Reason: I would like to have a kernel which uses the hardware to its full capacity, be able to use the latest instruction sets, for max. performance. I did some tests, started with compiling stable 3.9.7 on my 12.04 LTS box, and during compilation I choose processor vendor AMD (unchecked Intel/VIA/etc.), and when I started Ubuntu with this compiled kernel, in the section "System Settings - Additional Drivers" I found that, in addition to graphic card's drivers, there were AMD family 15h drivers also. However, I would prefer something in this regard tested/signed by Ubuntu developers. P.S: 1- the kernel that I have compiled has some issues with Nvidia graphics drivers, so I deleted kernel 3.9.7 and installed signed 3.8.xx from Ubuntu repositories. 2- incase if somebody is planning to advise me to install "AMD64", I am not talking about AMD64 (which is in fact for 64-bit platform).

  • Clean Code Development & Flexible work environment - MSCC 26.10.2013

    Finally, some spare time to summarize my impressions and experiences of the recent meetup of Mauritius Software Craftsmanship Community. I already posted my comment on the event and on our social media networks: Professional - It's getting better with our meetups and I really appreciated that 'seniors' and 'juniors' were present today. Despite running a little bit out of time it was really great to see more students coming to the gathering. This time we changed location for our Saturday meetup and it worked out very well. A big thank you to Ebene Accelerator, namely Mrs Poonum, for the ability to use their meeting rooms for our community get-together. Already some weeks ago I had a very pleasant conversation with her about the MSCC aims, 'mission' and how we organise things. Additionally, I think that an environment like the Ebene Accelerator is a good choice as it acts as an incubator for young developers and start-ups. Reactions from other craftsmen Before I put my thoughts about our recent meeting down, I'd like to mention and cross-link to some of the other craftsmen that were present: "MSCC meet up is a massive knowledge gaining strategies for students, future entrepreneurs, or for geeks all around. Knowledge sharing becomes a fun. For those who have not been able to made it do subscribe on our MSCC meet up group at meetup.com." -- Nitin on Learning is fun with #MSCC #Ebene Accelerator "We then talked about the IT industry in Mauritius, salary issues in various field like system administration, software development etc. We analysed the reasons why people tend to hop from one company to another. That was a fun debate." -- Ish on MSCC meetup - Gang of Geeks "Flexible Learning Environment was quite interesting since these lines struck cords : "You're not a secretary....9 to 5 shouldn't suit you"....This allowed reflection...deep reflection....especially regarding the local mindset...which should be changed in a way which would promote creativity rather than choking it till death..." -- Yannick on 2nd MSCC Monthly Meet-up And others on Facebook... ;-) Visual impressions are available on our Meetup event page. More first time attendees We great pleasure I noticed that we have once again more first time visitors. A quick overlook showed that we had a majority of UoM students in first, second or last year. Some of them are already participating in the UoM Computer Club or are nominated as members of the Microsoft Student Partner (MSP) programme. Personally, I really appreciate the fact that the MSCC is able to gather such a broad audience. And as I wrote initially, the MSCC is technology-agnostic; we want IT people from any segment of this business. Of course, students which are about to delve into the 'real world' of working are highly welcome, and I hope that they might get one or other glimpse of experience or advice from employees. Sticking to the schedule? No, not really... And honestly, it was a good choice to go a little bit of the beaten tracks. I mean, yes we have a 'rough' agenda of topics that we would like to talk about or having a presentation about. But we keep it 'agile'. Due to the high number of new faces, we initiated another quick round of introductions and I gave a really brief overview of the MSCC. Next, we started to reflect on the Clean Code Developer (CCD) - Red Grade which we introduced on the last meetup. Nirvan was the lucky one and he did a good job on summarizing the various abbreviations of the first level of being a CCD. Actually, more interesting, we exchanged experience about the principles and practices of Red Grade, and it was very informative to get to know that Yann actually 'interviewed' a couple of friends, other students, local guys working in IT companies as well as some IT friends from India in order to counter-check on what he learned first-hand about Clean Code. Currently, he is reading the book of Robert C. Martin on that topic and I'm looking forward to his review soon. More output generates more input What seems to be like a personal mantra is working out pretty well for me since the beginning of this year. Being more active on social media networks, writing more article on my blog, starting the Mauritius Software Craftsmanship Community, and contributing more to other online communities has helped me to receive more project requests, job offers and possibilities to expand my business at IOS Indian Ocean Software Ltd. Actually, it is not a coincidence that one of the questions new craftsmen should answer during registration asks about having a personal blog. Whether you are just curious about IT, right in the middle of your Computer Studies, or already working in software development or system administration since a while you should consider to advertise and market yourself online. Easiest way to resolve this are to have online profiles on professional social media networks like LinkedIn, Xing, Twitter, and Google+ (no Facebook should be considered for private only), and considering to have a personal blog. Why? -- Be yourself, be proud of your work, and let other people know that you're passionate about your profession. Trust me, this is going to open up opportunities you might not have dreamt about... Exchanging ideas about having a professional online presence - MSCC meetup on the 26th October 2013 Furthermore, consider to put your Curriculum Vitae online, too. There are quite a number of service providers like 1ClickCV, Stack Overflow Careers 2.0, etc. which give you the ability to have an up to date CV online. At least put it on your site, next to your personal blog. Similar to what you would be able to see on my site here. Cyber Island Mauritius - are we there? A couple of weeks ago I got a 'cold' message on LinkedIn from someone living in the U.S. asking about the circumstances and conditions of the IT world of Mauritius. He has a great business idea, venture capital and is currently looking for a team of software developers (mainly mobile - iOS) for a new startup here in Mauritius. Since then we exchanged quite some details through private messages and Skype conversations, and I suggested that it might be a good chance to join our meetup through a conference call and see for yourself about potential candidates. During approximately 30 to 40 minutes the brief idea of the new startup was presented - very promising state-of-the-art technology aspects and integration of various public APIs -, and we had a good Q&A session about it. Also thanks to the excellent bandwidth provided by the Ebene Accelerator the video conference between three parties went absolutely well. Clean Code Developer - Orange Grade Hahaha - nice one... Being at the Orange Tower at Ebene and then talking about an Orange Grade as CCD. Well, once again I provided an overview of the principles and practices in that rank of Clean Code, and similar to our last meetup we discussed on the various aspect of each principle, whether someone already got in touch with it during studies or work, and how it could affect their future view on their source code. Following are the principles and practices of Clean Code Developer - Orange Grade: CCD Orange Grade - Principles Single Level of Abstraction (SLA) Single Responsibility Principle (SRP) Separation of Concerns (SoC) Source Code conventions CCD Orange Grade - Practices Issue Tracking Automated Integration Tests Reading, Reading, Reading Reviews Especially the part on reading technical books got some extra attention. We quickly gathered our views on that and came up with a result that ranges between Zero (0) and up to Fifteen (15) book titles per year. Personally, I'm keeping my progress between Six (6) and Eight (8) titles per year, but at least One (1) per quarter of a year. Which is also connected to the fact that I'm participating in the O'Reilly Reader Review Program and have a another benefit to get access to free books only by writing and publishing a review afterwards. We also had a good exchange on the extended topic of 'Reviews' - which to my opinion is abnormal difficult here in Mauritius for various reasons. As far as I can tell from my experience working with Mauritian software developers, either as colleagues, employees or during consulting services there are unfortunately two dominant pattern on that topic: Keeping quiet Running away Honestly, I have no evidence about why these are the two 'solutions' on reviews but that's the situation that I had to face over the last couple of years. Sitting together and talking about problematic issues, tackling down root causes of de-motivational activities and working on general improvements doesn't seem to have a ground within the IT world of Mauritius. Are you a typist or a creative software craftsman? - MSCC meetup on the 26th October 2013 One very good example that we talked about was the fact of 'job hoppers' as you can easily observe it on someone's CV - those people change job every single year; for no obvious reason! Frankly speaking, I wouldn't even consider an IT person like to for an interview. As a company you're investing money and effort into the abilities of your employees. Hiring someone that won't stay for a longer period is out of question. And sorry to say, these kind of IT guys smell fishy about their capabilities and more likely to cause problems than actually produce productive results. One of the reasons why there is a probation period on an employment contract is to give you the liberty to leave as early as possible in case that you don't like your new position. Don't fool yourself or waste other people's time and money by hanging around a full year only to snatch off the bonus payment... Future outlook: Developer's Conference Even though it is not official yet I already mentioned it several times during our weekly Code & Coffee sessions. The MSCC is looking forward to be able to organise or to contribute to an upcoming IT event. Currently, the rough schedule is set for April 2014 but this mainly depends on availability of location(s), a decent time frame for preparations, and the underlying procedures with public bodies to have it approved and so on. As soon as the information about date and location has been fixed there will be a 'Call for Papers' period in order to attract local IT enthusiasts to apply for a session slot and talk about their field of work and their passion in IT. More to come for sure... My resume of the day It was a great gathering and I am very pleased about the fact that we had another 15 craftsmen (plus 2 businessmen on conference call plus 2 young apprentices) in the same room, talking about IT related topics and sharing their experience as employees and students. Personally, I really appreciated the feedback from the students about their current view on their future career, and I really hope that some of them are going to pursue their dreams. Start promoting yourself and it will happen... Looking forward to your blogs! And last but not least our numbers on Meetup and Facebook have been increased as a direct consequence of this meetup. Please, spread the word about the MSCC and get your friends and colleagues to join our official site. The higher the number of craftsmen we have the better chances we have t achieve something great! Thanks!

  • Running multiple box2D world objects on a server

    - by CharbelAbdo
    I'm creating a multiplayer game using LibGdx (with Box2d) and Kryonet. Since this is the first time I work on multiplayer games, I read a bit about server - client implementations, and it turns out that the server should handle important tasks like collision detection, hits, characters dying etc... Based on some articles (like the excellent Gabriel Gambetta Fast paced multiplayer series), I also know that the client should work in parallel to avoid the lag while the server responds to commands. Physics wise, each game will have 2 players, and any projectiles fired. What I'm thinking of doing is the following: Create a physics world on the client When the game is signaled to start, I create the same physics world on the server (without any rendering obviously). Whenever the player issues a command (move or fire), I send the command to the server and immediately start processing it on the client. When the server receives the command, it applies it on the server's world (set velocity etc...) Each 100ms, the server sends the new state to the client which corrects what was calculated locally. Any critical action (hit, death, level up) is calculated only on the server and sent to the client. Essentially, I would have a Box2d World object running on the server for each game in progress, in sync with the worlds running on the clients. The alternative would be to do my own calculations on the server instead of relying on Box2D to do them for me, but I'm trying to avoid that. My question is: Is it wise to have, for example, 1000 instances of the World object running and executing steps on the server? Tomcat used around 750 MBytes of memory when trying it without any object added to the world. Anybody tried that before? If not, is there any alternative? Google did not help me, are there any guidelines to use when you want to have physics on both the client and the server? Thanks for any help.

  • How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

    - by András Szepesházi
    If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical. EDIT: Thanks to everyone for their great insights. I've accepted EpsilonVector's answer as his analogy was the closest one to my original needs. The "falling asleep" explanation is neither offensive nor technical, almost anyone can relate to it, and the consequences of getting disturbed while falling asleep or while being in the zone are very similar: you experience frustration and you "lose" 15-20 minutes of time.

  • What causes player box/world geometry glitches in old games?

    - by Alexander
    I'm looking to understand and find the terminology for what causes - or allows - players to interfere with geometry in old games. Famously, ID's Quake3 gave birth to a whole community of people breaking the physics by jumping, sliding, getting stuck and launching themselves off points in geometry. Some months ago (though I'd be darned if I can find it again!) I saw a conference held by Bungie's Vic DeLeon and a colleague in which Vic briefly discussed the issues he ran into while attempting to wrap 'collision' objects (please correct my terminology) around environment objects so that players could appear as though they were walking on organic surfaces, while not clipping through them or appear to be walking on air at certain points, due to complexities in the modeling. My aim is to compose a case study essay for University in which I can tackle this issue in games, drawing on early exploits and how techniques have changed to address such exploits and to aid in the gameplay itself. I have 3 current day example of where exploits still exist, however specifically targeting ID Software clearly shows they've massively improved their techniques between Q3 and Q4. So in summary, with your help please, I'd like to gain a slightly better understanding of this issue as a whole (its terminology mainly) so I can use terms and ask the right questions within the right contexts. In practical application, I know what it is, I know how to do it, but I don't have the benefit of level design knowledge yet and its technical widgety knick-knack terms =) Many thanks in advance AJ

  • Simple monitoring of a Raspberry Pi powered screen - Part 2

    - by Chris Houston
    If you have read my previous blog post Raspberry Pi entrance signed backed by Umbraco - Part 1 which describes how we used a Raspberry Pi to drive an Entrance sign for QV Offices you will have seen I mentioned a follow up post about monitoring the sign.As the sign is mounted in the entrance of the building on the ground floor and the reception is on the 1st floor, this meant that if there was a fault of any kind showing on the screen, the first person to see this was inevitably one of QV Offices' clients as they walked into the building.Although the QV Offices' team were able to check the Umbraco website address that the sign uses, this did not always mean that everything was working as expected. We noticed a couple of times that the sign had Wifi issues (it is now hard wired) and this caused the Chromium browser to render a 404 error when it tried to refresh the screen.The simple monitoring solutionWe added the following line to our refresh script, so that after the sign had been refreshed a screen shot of the Raspberry Pi would be taken:import -display :0 -window root ~/screenshot.jpgFinally we wrote a small Crontab task that ran on a QV Offices Mac that grabs this screen shot and saved it on the desktop, admittedly we have used a package that it not mega secure, but in reality this is an internal system that only runs an office sign, so we are not to concerned about it being hacked.*/5 * * * * /usr/local/bin/sshpass -p 'password' /usr/bin/scp [email protected]:screenshot.jpg Desktop/QVScreenShot.jpgAs the file icon updates, if the image changes, this gives a quick visual indication of the status of the sign, if for some reason the icon does not look correct the QV Offices administrator can just click on the file to see the exact image currently displayed on the sign.Sometimes a quick and easy solution is better than a more complex and expensive one.

  • Example of persisting an inheritance relationship using ORM

    - by Schemer
    I have some experience with OOP and RDBs, but very little exposure to web programming. I am trying to understand what non-trivial types of problems are solved by ORM. Of course, I am familiar with the need for data persistence, but I have never encountered a need for persisting relationships between objects, a situation which is indicated in many online articles about ORM. I am not asking about the process of persisting a POJO to a database and restoring it later. Nor am I asking about why ORM frameworks are useful -- or a pain in the butt -- for doing so. I am particularly interested in how the need arises to persist and restore relationships between objects. In various documentation, I have seen many examples of persisting POJOs to a database, but the examples have all been for only very simple objects that are essentially nothing more than records anyway: a constructor, some private fields, and getter/setter methods. The motivation for persisting such an "object-record" seems obvious and trivial. This example: Hibernate ORM Tutorial offers such an example, but goes on to discuss mismatch issues of granularity, inheritance, identity, associations, and navigation that are not motivated by the example. If someone could offer a toy example of an instance where, say, the need arises to persist an inheritance relationship, I would be grateful. This might be blindingly obvious for anyone who has already encountered this situation but I have not and a great deal of searching and reading have not turned up any examples.

  • Designing web-based plugin systems correctly so they don't waste as many resources?

    - by Xeoncross
    Many CMS systems which rely on third parties for much of their code often build "plugin" or "hooks" systems to make it easy for developers to modify the codebase's actions without editing the core files. This usually means an Observer or Event design pattern. However, when you look at systems like wordpress you see that on every page they load some kind of bootstrap file from each of the plugin's folders to see if that plugin will need to run that request. Its this poor design that causes systems like wordpress to spend many extra MB's of memory loading and parsing unneeded items each page. Are there alternative ways to do this? I'm looking for ideas in building my own. For example, Is there a way to load all this once and then cache the results so that your system knows how to lazy-load plugins? In other words, the system loads a configuration file that specifies all the events that plugin wishes to tie into and then saves it for future requests? If that also performs poorly, then perhaps there is a special file-structure that could be used to make educated guesses about when certain plugins are unneeded to fullfil the request. Any ideas? If anyone wants an example of the "plugin" concept you can find one here.

  • Laptop Charger Not Recognised Properly on Samsung NP900X3F

    - by user193732
    Firstly thanks for your time. Secondly, having an issue with my power charger on my Samsung Series 9 NP900X3F. When I boot into Ubuntu with the charger plugged in it recognises it as charging. When I unplug the charger after this it is still says it is charging. If I suspend in Ubuntu then plug/unplug during this suspended state it recognises it, but not during normal running. If I knew a little more I'm sure I could grab logs and find out what the difference between wake on suspend and normal running is, but alas I need help! I also am having issues with my keyboard backlight via the fn keys, but that I care about far less. Thank you very much. Linux mikey-900X3F 3.12.0-031200rc1-generic #201309161735 SMP Mon Sep 16 21:38:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (I upgraded my kernel version to remove heinous horizontal artefacts I was getting) Happy to list more info about my system, ima bit of a noob. I did try searching however I can't find any questions at all about my system or related models with the same issue.
