  • When does a programmer know when a new job is not right?

    - by Mysterion
    I believe that the interview process is a selling of both parties - what can the employee offer the employer and vice versa. Assuming an individual has been careful in selecting their new employer (via thorough questioning in the interview process), however when they arrive at the job they find the employer has not been honest about certain aspects of the job. Examples of this dishonesty could include: The employee making it clear that technical excellence is an important factor, which is promised by the employer, but is not fully delivered or a good technical structure does not exist. The employee states they want to work on well architected and short (lets say less than 1 yr) long projects, yet when they start they find they are placed on a poorly architected older project. The employee being told of a pair programming environment to get him up to speed on the project, but being left to his own devices/questioning on arrival. The employee is promised a culture that encourages innovation and technical excellence but finds that this is not the case (eg. using technology for knowledge retention is laughed at). I know that a lot of famous developers feel that you make the place you work at. Is it realistic for a new employee with limited experience in the industry (say less than 5 years) to be able to join the company and change attitudes or even challenge the employer on the perceived dishonesty? Should they stay in this job or cut their losses?

  • Any danger in using the Wine workaround in 12.04?

    - by TrailRider
    To run certain Windows programs in WINE you need to this workaround: echo 0|sudo tee /proc/sys/kernel/yama/ptrace_scope According to the support websites, this is due to a bug in the Ubuntu kernel that prevents ptrace and WINE playing well together. Using the above command you set the ptrace to 0 which according the research I've done(don't ask me which websites, I have seem a lot of them), ptrace has to do with the interactions between programs. The 0 setting is more permissive than the 1. I have to assume that there was a good reason Ubuntu wanted the ptrace=1 so this leads me back to the short form of the question. Are there any risks involved in setting ptrace=0. Lower security? problems debugging? any others that I haven't thought of??? P.S. for anybody reading this that wonders what the bug causes, the Windows programs will fail to open at all, in the System Monitor you will see many instances of the program trying to open and then they will eventually all quit and if you run the progam for the terminal you will get an error that tells you that the maximum number of program instances has been reached.

  • How can I deal with a difficult developer that is holding back the project? [migrated]

    - by ILovePaperTowels
    Our entire project is being held up because of one piece which is being handled by a single developer. When we did finally got the latest version of his code and started reviewing it, we found the code was horrendous! Its a relatively simply workflow, however the code is so complex that it's very difficult to step through and review/debug. The developer responsible has a hard time accepting any kind of criticism, and feels he is more knowledgeable than others members of the team. It's difficult to even talk to him about his development work because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but management is not doing anything. This is probably because devs are in short supply where we are, and this is a corporation has a lot of office drama. I'm just one of the developers, not the project manager, however I really want to see this project succeed. What can I do in this sort of situation to try and keep the project on track?

  • Costs/profit of/when starting an indie company

    - by Jack
    In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

  • Skillset improvement in coming new year

    - by exiter2000
    Here is a little background information. I have been working for Java 10 years. The product I am working on went to live about 3 years ago. Now, the product is getting stable. After all the post-product drama, I gained a lot of knowledge about Oracle & SQL. People(mainly management) were desperated enough to give me deep oracle-related task over DBAs. I admit I considered becoming DBA but eventually decided to remain as a programmer. DBAs & Management are demanding all the DB & Query related task back to DBA, which makes me a bit sad. In short, I anticipate a lot of time next year. What would you do to improve your skillset?? I am thinking to upgrade my Java version(Not from experience though, we are using JDK1.5) to 1.6 getting certificate. Any good idea from fellow developers?? -----------Edit --------------------- How about data modeling for application? Do you guys think it is developer role??

  • Dealing with Fine-Grained Cache Entries in Coherence

    - by jpurdy
    On occasion we have seen significant memory overhead when using very small cache entries. Consider the case where there is a small key (say a synthetic key stored in a long) and a small value (perhaps a number or short string). With most backing maps, each cache entry will require an instance of Map.Entry, and in the case of a LocalCache backing map (used for expiry and eviction), there is additional metadata stored (such as last access time). Given the size of this data (usually a few dozen bytes) and the granularity of Java memory allocation (often a minimum of 32 bytes per object, depending on the specific JVM implementation), it is easily possible to end up with the case where the cache entry appears to be a couple dozen bytes but ends up occupying several hundred bytes of actual heap, resulting in anywhere from a 5x to 10x increase in stated memory requirements. In most cases, this increase applies to only a few small NamedCaches, and is inconsequential -- but in some cases it might apply to one or more very large NamedCaches, in which case it may dominate memory sizing calculations. Ultimately, the requirement is to avoid the per-entry overhead, which can be done either at the application level by grouping multiple logical entries into single cache entries, or at the backing map level, again by combining multiple entries into a smaller number of larger heap objects. At the application level, it may be possible to combine objects based on parent-child or sibling relationships (basically the same requirements that would apply to using partition affinity). If there is no natural relationship, it may still be possible to combine objects, effectively using a Coherence NamedCache as a "map of maps". This forces the application to first find a collection of objects (by performing a partial hash) and then to look within that collection for the desired object. This is most naturally implemented as a collection of entry processors to avoid pulling unnecessary data back to the client (and also to encapsulate that logic within a service layer). At the backing map level, the NIO storage option keeps keys on heap, and so has limited benefit for this situation. The Elastic Data features of Coherence naturally combine entries into larger heap objects, with the caveat that only data -- and not indexes -- can be stored in Elastic Data.

  • New Horizon

    - by alexismp
    I have resigned from Oracle and thus will soon leave the GlassFish group. I feel very proud looking back at what we've achieved as a team with GlassFish in the past few years, including those past two years at Oracle. If you know anything about the history of application servers at Sun, you'll recognize that building such a community around GlassFish and its amazing number of downloads is nothing short of a small miracle. The Java EE platform has also seen a strong resurgence, bringing it back to the forefront of effective enterprise Java development in many ways. Having been hired by Sun some 13 years ago to sell NetDynamics I certainly feel that I leave the company's application server in *much* better shape. Oracle has ambitious plans for GlassFish and has been in my opinion a good steward for this community. I see no reason for this to change and I do expect the community to keep on pushing Oracle to get even better with time. This ride has been intense and the people I've met and worked with, both inside and outside Sun/Oracle, have made the experience the best one of my career. My journey now continues here: alexismp.wordpress.com. See you there!

  • Windows Defender Update KB915597 (Definition 1.135.415.0)? Killed My Live Discs

    - by user88311
    Here's my problem, for those willing to read for about 2 minutes here's the entire story, http://answers.microsoft.com/en-us/windows/forum/windows_vista-windows_update/bsod-after-windows-defender-update-kb915597/a4b5fca3-0274-47b4-97c4-61b34c4c4599, for those who want the short version here's what happened. After windows update automatically updated windows defender to kb915597, my computer starting getting bsods on shut down and start up and started experiencing problems withe the usb ports. So I decided to go to the microsoft answers site for help, I know that was probably my first mistake, so I followed their advice and they turned my computer into a large paper weight. Luckily I make physical backups of my c drive every few months and I have one from back in july, so I figured I'd boot up a ubuntu live disc, copy all my files from the past 2 months to a external drive and just copy the backup back to the c drive, that's where I ran into this problem. When I put in either a ubuntu or kubuntu disc, everything goes well, until it finishes the loading bar then when the OS would presumably start up, the computer resets, I've tried with ubuntu, kubuntu and gparted, and only gparted is able to get to the point where it starts up, but even then when I try to access the internet from it, the computer resets, and when I tried to copy the entire C drive partition to a blank external I wasn't able to. So I figured somehow maybe the C drive had something to do with it, so I unplugged the C drive so my computer was just a 2.8 ghz processor and 2 gigs of ram, should have had no problem starting a live disc but the problem still continues. After doing some googling around I've found whenever windows gets a update with the title KB915597 it's pretty much the kill switch for windows, I've tried contacting microsoft tech support and even managed to directly contact a software engineer but as soon as I mention KB915597 they all just blew me off. I hope anybody who reads this has any idea how to fix this, I'm going to attempt to install ubuntu or kubuntu to a external drive using the same computer and see what happens now.

  • Is it possible to have multiple subdomains point to the same Blogger blog?

    - by cclark
    For our application we want to have a status page which is hosted outside of the rest of our infrastructure so in case there are issues in our data center we can post updates for our users and our users will be able to access them. We registered a blog on Blogger and set it up with xyzstatus.blogspot.com and status.xyz.com. Everything seems to work fine. We need to perform some maintenance at our datacenter which will sever all connectivity so we're unable to have a redirect using nginx or apache. We'd like to do this with a short TTL CNAME DNS entry. Ideally www.xyz.com and app.xyz.com could be CNAMEd to status.xyz.com. When I setup the CNAME and go to that URL I get a Google broken robot 404 page. I figure I must need to let Google know it should associate traffic to www.xyz.com and app.xyz.com to the blog served up by status.xyz.com. But I can't see anywhere to do this in Blogger. Does anyone know if this is possible?

  • Fault Handling Slides and Q&A by Vennester

    - by JuergenKress
    Fault Handling It is one thing to architect, design, and code the “happy flow” of your automated business processes and services. It is another thing to deal with situations you do not want or expect to occur in your processes and services. This session dives into fault handling in Oracle Service Bus 11g and Oracle SOA Suite 11g, based on an order-to-cash business process. Faults can be divided into business faults, technical faults, programming errors, and faulty user input. Each type of fault needs a different approach to prevent them from occurring or to deal with them. For example, apply User Experience (UX) techniques to improve the quality of your application so that faulty user input can be prevented as much as possible. This session shows and demos what patterns and techniques can be used in Oracle Service Bus and Oracle SOA Suite to prevent and handle technical faults as well as business faults. Q&A This section lists answers to the questions that were raised during the preview event. Q: Where can retries be configured in Oracle Service Bus? The retry mechanism is used to prevent faults caused by temporary glitches such as short network interruptions. A faulted message is resend (retried) and might succeed this time since the glitch has passed. Retries are an out-of-the-box feature that can be used in Oracle Service Bus and Oracle SOA Suite using the Fault Policy framework. By default, retries are disabled in Oracle Service Bus.

  • Should I sell video tutorials on my own or via publishers like lynda.com? [closed]

    - by Derfder
    I am asking this because I am deciding between two models right now. One way is to create video tutorials on my own (make some short free videos and long pay per download/stream videos) or sell them to lynda.com or tutsplus. The 2nd way is easier, because they will do all the boring business stuff, will host the files to download etc. In that case, everything I need is a good microphone and obey their guidelines. On the other side if I do it on my own, I have to do all the unwanted business stuff, pay the server and other stuff. This is quite a big downside, however, I will have all the videos under my control in the future. I know that lynda.com has bigger attention and marketing that I am capable, but if you take e.g. phpvideotutrials.com (r.i.p ;), I think Leigh was very successful with relatively small budget. The interesting question will be the cost or how much will they pay me. Would it be less than if I sell it myself+monthly server hosting+other expenses? Any advice from people who actively sell their videos to some companies or do it on they own is highly appreciated.

  • What do I need to Mod a Unreal Engine 3 game?

    - by RoadSideWarrior
    what I am looking for is some advise making a mod for a certain game and how I would go about making it. The game I am talking about is Blacklight: Retribution and what I wan't to know is; Is it possible? And if so, what programs will I need? It is an online only game so I was unsure how plausible a mod would be for it. Plus I have never made a video game before, but I do like the game and I wanted to do some things with it. Additionally, this will be my first time making anything video game related so I would appreciate any advise. To expand a bit, I plan to add something simple at first. A mod that would let you spectate another player in the first person. Then I plan do something a bit more complex where I want to make so the game optionally always records you playing (in short intervals most likely or you would run quickly out of memory). After all that is done I would add items, armor, weapons, and maybe make a map or not I am not sure but this in a shell what I hope to do. I don't know much about these things but I am reading anything I can get my hands on. So if this is overly ambitious or just plain out not a possibility any advise on what I should look to instead will be welcomed warmly. Thank you.

  • Using ASP.NET, Membership, and jQuery to Determine Username Availability

    Chances are, at some point you've tried creating a new user account on a website and were told that the username you selected was already taken. This is especially common on very large websites with millions of members, but can happen on smaller websites with common usernames, such as people's names or popular words or phrases in the lexicon of the online community that frequents the website. If the user registration process is short and sweet, most users won't balk when they are told their desired username has already been taken - they'll just try a new one. But if the user registration process is long, involving several questions and scrolling, it can be frustrating to complete the registration process only to be told you need to return to the top of the page to try a different username. Many websites use Ajax techniques to check whether a visitor's desired username is available as soon as they enter it (rather than waiting for them to submit the form). This article shows how to implement such a feature in an ASP.NET website using Membership and jQuery. This article includes a demo available for download that implements this behavior in an ASP.NET WebForms application that uses the CreateUserWizard control to register new users. However, the concepts in this article can be applied to ad-hoc user registration pages and ASP.NET MVC. Read on to learn more! Read More >

  • My Kids and Ear Infection

    - by heshamelsaghir
    My Kids and Ear Infection is becoming a weekly issue.  That is why I wanted to start this blog to talk about my experience and more important hear from other parents opinions and experience. Well, I will start with my twins, they are about 3yrs old.  started to go to day care about three months ago.  since they started with the daycare, they started getting exposed to germs and viruses and the ear infection started too.  every few weeks they have ear infection.  They take turns or some times they both get ear infection at the same time.  To be more accurate, one of them is more suseptive to the ear infection.  We ended up going through the specialest that suggested an ear tube operation and also remove the adenoid tissue.  His opinion was that will stop the fluid from staying in his inner ear and will eleminate the ear infedction.  To make the long story short for now.  the ear infection never stoped.  in addtion to the ear infection, now the tube is stuck and stoped working, the tube is moved and going to fall, as the doctor said.  the problems do not stop.  they keep adding up.  and now my second son is going to need ear tube if he gets ear infection again.  what should I do?

  • How to handle the different frame rate on different devices?

    - by Fenwick
    I am not quite sure how frame per second works on a web page. I have a Canvas game that involves in moving an image from point A to B, and measuring the time elapsed. The code can be as simple as: var timeStamp = Date.now(); function update(){ obj.y += obj.speed; text = "Time: "+ (Date.now() - timeStamp) + "ms"; } The function update() is called every frame. The problem is that the time elapsed is different from device to device. It is pretty short on my PC, but get longer on my iPad, and is much longer on my cell phone. I thought it is because the FPS is smaller on mobile devices, so instead of calling update() every frame, I call it every 1ms by using a setInterval. But this does not solve the problem. In my understanding, the function for setInterval is invoked based on the increment in system time, other than frame rate, so it should fix the problem. Am I missing anything here? If the setInterval function is called based on FPS, is there any way to get around with the FPS difference across devices? On a side note, I have sort of a "water simulator" on the same canvas. It involves in redrawing about 60 objects which can be 600x600 pixels for every frame, so it could be a frame rate killer. I am using Phaser.js but not really using much of its functionalities, if that helps.

  • Windows 8.1 - unfixable grub

    - by Nick
    I have a Gigabyte laptop that came with secure boot and windows 8. After a bit of battling, I managed to get my dual boot with Ubuntu 13.10.. Anyway, I upgraded zindows to 8.1, now grub is gone. I restarted from a live CD and chrooted to my drive. I used boot-repair multiple times (with successful output) both in default and with some advanced options; also reinstalled grub manually... Each time it tries once to boot to grub but gives a message for a very short amount of time. I recorded it and it is a regular bios message "Rebbot and Select proper Boot device of Insert Boot media in selected boot device and press a key" I even tried something called EasyBCD under winblows, it shows the correct boot options, but same there, it is unable to make the linux partition fire up. Anyway, no way to boot my linux box. Does anyone have an idea how to fix this? No need to redirect me to another post with grub reinstall or boot-repair, seen them all... I am thinking of trying this other boot loader, refind, to see if it works http://www.rodsbooks.com/refind/index.html Also re-reading this bios message, I'm thinking my partition might not have a boot flag anymore... I'll try that too with parted. Although both grub and win 8 are supposed to fire up from the same boot partition (the EFI one) Please help! thx

  • Any examples of fair mmo games with quick completion

    - by Keith Player
    I'm looking for some example games for inspiration that allow from 10 to a large number of players at a time and can be completed in 10 to 30 minutes. I'm looking for something that would have extremely low bandwidth and not be dependent on chance or luck (i.e one player can't gain an unfair advantage because the computer put them in a better position). Realized on the way home that more clarifications might have been helpful. I'm looking to develop a pay-to-play competition that would allow a large number of players to compete in a relatively short period of time. One way would be to have an mmo that can be completed in 30 minutes, another way would be if you could have 10 person games that finish in under 5 minutes and then have the winners compete against each other until a winner is decided. I'm interested in any genre that would make for a fun/interesting game that doesn't depend on luck, so all players should have the same choice/availability of activities/resources and follow the same rules. Some possible games that could possibly be modified into what I want, would be bztanks (too easy to create a bot), diplomacy (takes too long), risk, some chess like game. I was just wondering if there are other game types to the ones I have been considering.

  • In MVC, why can't a model create a view?

    - by MUY Belgium
    I have a web application written in Perl with a controller, some "views" and some "Models". Each "Model" is corresponding to one "View". The controller (one file) creates an Model object corresponding to each view (view is a CGI argument) then retrieve the view from the module it has just created. Indeed, this should be bad thing but can you argue a bit more about it. My first idea was that since the object "Model" depends upon the "view", then the "model" is actually a view. But also the fact that ALL the cgi parameters are passed to the Model causes the "Model" to become not truelly a view but to loose all interest, since it is only related to the current implementation of the web apps. On other words, that the "Model" keep model but loose its "comprehensiveness" ("Model" is not easily understandable). I'm am quite new in project analysis, so please do not be too harsh. Why is this bad? I have made a prototype with the main structures I have understood of this web application, made as short as possible. #Model.pm package Model; import { # this requires an attribute called "view" # and this require an argument which is the cgi params } ... #View1.pm package View1; ... #Model1.pm package ModelView1 ; base Model; use View1; sub new { my $class = shift; my $arg = shift; Model::DoSomething($arg); $self->view = new View1($arg); ... } #controller.cgi my $model = 0; ... $model = new Model1( cgi_param => params() ); #there is severall models here ... print $model->get_view()->get_html();

  • Login takes very long, annoying repaints once a minute when logged in: How to troubleshoot?

    - by user946850
    I am suffering from a strange problem with my Gnome Shell in Ubuntu 12.10. The login takes very long ( 30 sec), with a blank screen. In Google Chrome and Thunderbird (and perhaps in other applications), the main window freezes and is repainted in periodic intervals of less than one minute. The freeze takes several seconds, and it seems that font and appearance of, e.g., tabs and buttons briefly changes. Attempting to enable the second monitor show an error message related to XRANDR. Everything seems to have started three days ago, after I had to force-shutdown the machine while it was hibernating due to low power. (It was hibernating for quite a while and didn't want to stop.) Silly me. I have tried the following measures, with no avail: Checked all package file md5 hashes using debsums Reinstalled all packages using a variant of dpkg --get-selection \* | xargs apt-get install -reinstall Temporarily moved configuration directories such as .gconf, .config and .gnome2 to another location Created a new user account When I choose "Ubuntu" during login, the problems disappear. I am sort of frustrated that reinstalling all packages didn't fix the issue. How to troubleshoot this Gnome Shell (?) problem, short of reinstalling the system? (Or did anyone see this kind of behavior on their machine?)

  • Are specific types still necessary?

    - by MKO
    One thing that occurred to me the other day, are specific types still necessary or a legacy that is holding us back. What I mean is: do we really need short, int, long, bigint etc etc. I understand the reasoning, variables/objects are kept in memory, memory needs to be allocated and therefore we need to know how big a variable can be. But really, shouldn't a modern programming language be able to handle "adaptive types", ie, if something is only ever allocated in the shortint range it uses fewer bytes, and if something is suddenly allocated a very big number the memory is allocated accordinly for that particular instance. Float, real and double's are a bit trickier since the type depends on what precision you need. Strings should however be able to take upp less memory in many instances (in .Net) where mostly ascii is used buth strings always take up double the memory because of unicode encoding. One argument for specific types might be that it's part of the specification, ie for example a variable should not be able to be bigger than a certain value so we set it to shortint. But why not have type constraints instead? It would be much more flexible and powerful to be able to set permissible ranges and values on variables (and properties). I realize the immense problem in revamping the type architecture since it's so tightly integrated with underlying hardware and things like serialization might become tricky indeed. But from a programming perspective it should be great no?

  • What's the right/standard way of achieving separation of concerns?

    - by Ghanima
    Some background: I want to start developing games, and taking some of the advice given in this site, I've started with something simple and familiar, such as pong, tetris, etc. I want to take as much time as needed to make sure that I have the basics right before moving on to something bigger. I have medium programming experience but I realize making games is a different thing. I find myself wondering many things like should this be in a separate class? Should this module handle this stuff or is it better to let other modules have that kind of functionality? For example, the bouncing of a ball in pong, right now is handled in the ball module, but maybe it's better that some other module did it. Right now I have different modules: one for the graphics, one for the game logic, and others for the objects (depending on the kind of movement required, not all the objects are alike). I know I am asking a lot, any tips you have will be very much appreciated. Short question: What's the right or standard way of separating the modules? What have you found most effective? Is it enough to just keep the drawing (graphics) and the logic separate? Is it necessary to have a lot of classes? (for example for the objects in the game, to handle the movement, etc)
