  • How often do you review fundamentals?

    - by mlnyc
    So I've been out of school for a year and a half now. In school, of course we covered all the fundamentals: OS, databases, programming languages (i.e. syntax, binding rules, exception handling, recursion, etc), and fundamental algorithms. the rest were more in-depth topics on things like NLP, data mining, etc. Now, a year ago if you would have told me to write a quicksort, or reverse a singly-linked list, analyze the time complexity of this 'naive' algorithm vs it's dynamic programming counterpart, etc I would have been able to give you a decent and hopefully satisfying answer. But if you would have asked me more real world questions I might have been stumped (things like how would handle logging for an application, or security difference between GET and POST, differences between SQL Server and Oracle SQL, anything I list on my resume as currently working with [jQuery questions, ColdFusion questions, ...] etc) Now, I feel things are the opposite. I haven't wrote my own sort since graduating, and I don't really have to worry much about theoretical things that do not naturally fall into problems I am trying to solve. For example, I might give you some great SQL solutions using an analytical function that I would have otherwise been stumped on or write a cool web application using angular or something but ask me to write an algo for insertAfter(Element* elem) and I might not be able to do it in a reasonable time frame. I guess my question here to the experienced programmers is how do you balance the need to both learn and experiment with new technologies (fun!), working on personal projects (also fun!) working and solving real world problems in a timeboxed environment (so I might reach out to a library that does what I want rather than re-invent the wheel so that I can focus on the problem I am trying to solve) (work, basically), and refreshing on old theoretical material which is still valid for interviews and such (can be a drag)? Do you review older material (such as famous algorithms, dynamic programming, Big-O analysis, locking implementations) regularly or just when you need it? How much time do you dedicate to both in your 'deliberate practice' and do you have a certain to-do list of topics that you want to work on?

  • Enemy collision detection with movie clips

    - by user18080
    I have created multiple movieclips with animations within them. It is an obstacle avoidance game and I cannot seem to be able to get my enemies to contact my playableCharacter. The enemies I have created are each embedded on certain levels of my game. I have created an array, enemiesArray to have each of my enemies placed within it. Here is the code for that: //step 1: make sure array exists if(enemiesArray!=null && enemiesArray.length!=0) { //step 2: check all enemies against villain for(var i:int = 0;i < enemiesArray.length; i++) { //step 3: check for collision if(villain.hitTestObject(enemiesArray[i])) { //step 4: do stuff trace("HIT!"); removeChild(enemiesArray[i]); enemiesArray.splice(i,1); removeChild(villain); villain = null; } } } What I am unsure of is whether or not my enemiesArray is actually holding the movieclips I have suggested. If it was, this code would be tracing back a "HIT" for every time I ran into an enemy and would kill my character. It is not doing that however. I am thinking I have to push my movieclips into my array but I don't know how to do that or where for that matter. Any and all help would be much appreciated.

  • Never Bet Against the Impossible

    - by BuckWoody
    My uncle used to say “If a man tells you that his car squirts milk in his eye when you lift the hood, don’t bet against that. You’ll end up with milk in your eye.” My friend Allen White tells me this is taken from a play (and was said about playing cards), but I think the sentiment holds, even in database work. I mentioned the other day that you should allow the other person to talk and actively listen before you propose a solution. Well, I saw a consultant “bet against the impossible”  the other day – and it bit her. She explained to the person telling her the problem that the situation simply couldn’t exist that way, and he proceeded to show her that it did. She got silent, typed a few things, muttered a little, and then said “well, must be something else.” She just couldn’t admit she was wrong. So don’t go there. If someone explains a problem to you with their database, listen with purpose, and then explore the troubleshooting steps you know to find the problem. But keep your absolutes to yourself. In fact, I have a friend that has recently sent me one of those. He connects to a system with SQL Server Management Studio (SSMS) version 2008 (if I recall correctly) and it shows a certain version number of the target system in the connection tab. Then he connects to it using SSMS 2008 R2 and gets a different number. Now, as far as I know, we didn’t change the connection string information, and that’s provided by the target system, so this is impossible. But I won’t tell him that. Not until I look a little more. :) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • How to enable logging for Google Chrome in Ubuntu 12.04?

    - by skytreader
    I'm trying to capture the logs for a certain bug I'm having with Google Chrome. However, I can't find/enable logs for GC. According to this Chromium project page, I just need to add the flags --enable-logging --v=1 and a chrome_debug.log file will appear in my user data directory. However, after running GC (and closing through the 'X' title bar button) there is no chrome_debug.log file in the specified directory. I even tried running as root as it may have something to do with write permissions but GC refuses to start as root. Another thing, GC also prints messages when invoked from command line. I tried capturing this and redirecting them to a file via $ google-chrome > today.log but the messages are still printed in the command line and the file I specify gets created but remains empty. Note that I can't just copy-paste the messages printed on terminal after my bug occurs as the bug freezes up my whole system that, when it occurs, my only option is to turn off my computer straight via the power button. I've seen a few similar bugs already posted but I find that they don't exactly describe my situation so I'd really like to get some logs for this. So how do I enable logging or, at least, get those terminal messages in a file?

  • Standard/Compliance for web programming?

    - by MarkusK
    I am working with developers right now that write code the way they want and when i tell them to do it other way they respond that its just matter of preference how to do it and they have their way and i have mine. I am not talking about the formatting of code, but rather of way site is organized in classes and the way the utilize them. and the way they create functions and process forms etc. Their coding does not match my standards, but again they argue that its matter of preference and as long as goal achieved the can be different way's to do it. I agree but their way is proven to have bugs and we spend a lot of time going back and forth with them to fix all problems security or functionality, yet they still write same code no matter how many times i asked them to stop doing certain things. Now i am ready to dismiss them but friend of mine told me that he has same exact problem with freelance developers he work with. So i don't want to trade one bad apple for another. Question is is there some world wide (or at least europe and usa) accepted standard or compliance on how write secure web based applications. What application architecture should be for maintainable application. Is there are some general standard that can be used for any language ruby php or java govern security and functionality and quality of code? Or at least for PHP and MySQL i use for my website. So i can make them follow this strict standard and stop making excuses.

  • What's the best way to use requestAnimationFrame and fixed frame rates

    - by m90
    I recently got into using the HTML5-requestAnimationFrame-API a lot on animation-heavy websites, especially after seeing the Jank Busters talk. This seems to work pretty well and really improve performance in many cases. Yet one question still persists for me: When wanting to use an animation that is NOT entirely calculated (think spritesheets for example) you will have to aim for a fixed frame rate. Of course one could go back to use setInterval again, but maybe there are other ways to tackle this. The two ways I could think of using requestAnimationFrame with a fixed frame rate are: var fps = 25; //frames per second function animate(){ //actual drawing goes here setTimeout(function(){ requestAnimationFrame(animate); }, 1000 / fps) } animate(); or var fps = 25; //frames per second var lastExecution = new Date().getTime(); function animate(){ var now = new Date().getTime(); if ((now - lastExecution) > (1000 / fps)){ //do actual drawing lastExecution = new Date().getTime(); } requestAnimationFrame(animate); } animate(); Personally, I'd opt for the second option (the first one feels like cheating), yet it seems to be more buggy in certain situations. Is this approach really worth it (especially at low frame rates like 12.5)? Are there things to be improved? Is there another way to tackle this?

  • Been doing .NET for several years and am thinking about a platform change. Where do people suggest I go?

    - by rsteckly
    Hi, I've been programming in .NET for several years now and am thinking maybe its time to do a platform switch. Any suggestions about which platform would be the best to learn? I've been thinking about going back to C++ development or just focusing on T-SQL within the Microsoft stack. I'm thinking of switching because: a) I feel that the .NET platform is increasingly becoming commodified--meaning that its more about learning a GUI and certain things to click around than really understanding programming. I'm concerned that this will lend itself to making developers on that stack increasingly paid less. b) It's very frustrating to spend your entire day essentially debugging something that should work but doesn't. Usually, Microsoft releases something that suggests anyone can just click here and there and poof there's your application. Most of the time it doesn't work and winds up sucking so much more time than it was supposed to save. c) I recently led a team in a small startup to build a WPF application. We were really hit hard with people complaining about having to download the runtime. Our code was also not portable to any other platform. Added to which, the ram usage and slowness to load of the app was remarkable for its size. I researched it and we could not find a way to optimize it. d) I'm a little concerned about being wedded to the Windows platform. What are the pros and cons of adding another platform and which platform do people suggest? Thanks!

  • Why am I seeing so many instantiable classes without state?

    - by futlib
    I'm seeing a lot of instantiable classes in the C++ and Java world that don't have any state. I really can't figure out why people do that, they could just use a namespace with free functions in C++, or a class with a private constructor and only static methods in Java. The only benefit I can think of is that you don't have to change most of your code if you later decide that you want a different implementation in certain situations. But isn't that a case of premature design? It could be turned into a class later, when/if it becomes appropriate. Am I getting this wrong? Is it not OOP if I don't put everything into objects (i.e. instantiated classes)? Then why are there so many utility namespaces and classes in the standard libraries of C++ and Java? Update: I've certainly seen a lot examples of this in my previous jobs, but I'm struggling to find open source examples, so maybe it's not that common after all. Still, I'm wondering why people do it, and how common it is.

  • Hit Detection When rotating the camera

    - by SD1990
    This bug/feature has been plaguing me for a while and i want to know the best way to fix it. I'm testing simple hit detection with a wall, like: if (Forward button) if(Inv.w.z < -49 || Inv.w.z > 49) pos.z = 0.0f; else if(Inv.w.x < -49 || Inv.w.x > 49) pos.z = 0.0f; else pos.z = +1.0f; where Inv.w. is the camera positions. Now obviously when i now hit that certain point i can no longer move away from the wall or anywhere in fact. How can i change this code to allow for the camera to be turned away from the wall so therefore i should be allowed to move? for example, the player hits the wall and i cant move until i turn around or to the side? I know its something to do with velocity but im pretty new to this so please bare with me if this is easy.

  • Should I indicate that the user exists or was deleted on the error page?

    - by animuson
    On an ordinary public website, the user's profile is always publicly visible to all visitors (such as Stack Overflow), where they can limit certain pieces of information via privacy settings or just removing the information. Now the user has decided to delete their account (in my case deactivate) so that their account doesn't technically "exist" anymore. The way my system is set up, when their account is deactivated, their username for any content connected to them just becomes "Anonymous User" as if it were a guest that posted. I feel like this could cause some confusion for other users. I'm also concerned about what kind of error to display when someone attempts to view their profile page. My gut tells me to just display a standard 404 page to hide the fact that they ever existed, but then you also have to consider that, since usernames must be unique, anyone can go to the register page and type in the username to see if it really exists or not. I have a similar problem with another website, which gives users the ability to hide their profiles from the public and only allow registered users to view it. Again it's with the dilemma of what kind of error message to display when an unregistered users attempts to view their profile with invalid permissions. So, would it be acceptable to display basic errors such as "user has been deactivated" or "you must be logged in to view this profile" in order to give other visitors some idea of why the page can't be displayed, or should I attempt to cover the user's privacy a little and just display a standard 404 without indicating in any way that the user might exist? Are there any other issues that I'm not realizing about either route? To go back to the beginning, should I even bother changing the user's name to "Anonymous User" when their account is deactivated? Would it be acceptable to just display a non-linked version of their username in place of the normal linked display name?

  • Facebook contest policy no-no?

    - by Fred
    I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?

  • "Default approach" when creating a class from scratch: getters for everything, or limited access?

    - by Prog
    Until recently I always had getters (and sometimes setters but not always) for all the fields in my class. It was my 'default': very automatic and I never doubted it. However recently some discussions on this site made me realize maybe it's not the best approach. When you create a class, you often don't know exactly how it's going to be used in the future by other classes. So in that sense, it's good to have getters and setter for all of the fields in the class. So other classes could use it in the future any way they want. Allowing this flexibility doesn't require you to over engineer anything, only to provide getters. However some would say it's better to limit the access to a class, and only allow access to certain fields, while other fields stay completely private. What is your 'default' approach when building a class from scratch? Do you make getters for all the fields? Or do you always choose selectively which fields to expose through a getter and which to keep completely private?

  • Many user stories share the same technical tasks: what to do?

    - by d3prok
    A little introduction to my case: As part of a bigger product, my team is asked to realize a small IDE for a DSL. The user of this product will be able to make function calls in the code and we are also asked to provide some useful function libraries. The team, together with the PO, put on the wall a certain number of user stories regarding the various libraries for the IDE user. When estimating the first of those stories, the team decided that the function call mechanism would have been an engaging but not completely obvious task, so the estimate for that user story raised up from a simple 3 to a more dangerous 5. Coming to the problem: The team then moved to the user stories regarding the other libraries, actually 10 stories, and added those 2 points of "function call mechanism" thing to each of those user story. This immediately raised up the total points for the product of 20 points! Everyone in the team knows that each user story could be picked up by the PO for the next iteration at any time, so we shouldn't isolate that part in one user story, but those 20 points feel so awfully unrealistic! I've proposed a solution, but I'm absolutely not satisfied: We created a "Design story" and put those annoying 2 points over it. However when we came to realize and demonstrate it to our customers, we were unable to show something really valuable for them about that story! Here the problem is whether we should ignore the principle of having isolated user stories (without any dependency between them). What would you do, or even better what have you done, in situations like this? (a small foot-note: following a suggestion I've moved this question from stackoverflow)

  • License compatibility question

    - by Ivaylo Slavov
    I have a question regarding software licenses. I plan to put a license to a framework that I have written. My intention is that the license should be open, in order to maintain a community. Also I want to control when a new version is released and which changes will be included. The license should allow the framework to be used with commercial products, therefore respecting their own license. I have done some quick research and I decided to double license my work under the Apache License 2.0 (ASL) and Eclipse Public License (EPL). My point is that the EPL will provide me the ability to control the release cycle as well as the contributions to the project and the Apache license will take care for any patents a 3rd party might want to use in a derived work. Also both are open licenses. My question is related to the GLP and LGPL licenses. If I have the above licenses to my framework, will it be possible and legal, for someone to create a derived work of my framework, that is also a derived work of, or links a library that is under the LGPL license? Thanks in advance. EDIT: To be clear I will explain how I expect things to work. The framework will define some common API for certain functionalities as well as a Wrapper class that will invoke an implementation of that API. The Wrapper will be part of the framework, but it will internally call the actual implementation. This implementation should be in a separate library, and such libraries I would like to be developed and maintained by community. Surely the community will have to access the framework but I want to limit changes to the framework by the community but I want to provide freedom for any API implementation (a derived work of the framework). The framework will enable flexible configuration mechanisms that will tell which implementation of an API will be used.

  • Accidentally Changed Dual Monitor Setup and don't know how to reset it

    - by user203783
    I have a dual monitor setup with my laptop and an external Asus monitor running under Ubuntu 11.10. When I first started using Ubuntu, it synced both screens. What showed up on my laptop showed up on my eternal monitor. Last night, I accidentally knocked the HDMI cable from its port (not that unusual in the tight space I work in). When I plugged it back in, as usual, the external monitor only displayed my wallpaper. Usually, I just restart Ubuntu and it resets, but last night what I now realize was the display console came up and somehow I changed the setup. Now the two screens show different jobs so to speak. Also, the external monitor doesn't display the ribbon, making switching between Firefox tabs and windows or apps jarring. I write for a living and need to quickly check bits of research, notes or sources while writing and the extra switching between mouse pad and external mouse to get one or the other screen to respond interrupts my work flow. The only technical help I can offer is when the display console popped up, the graphical representation of the screens was that the external screen appeared layered over by about one-quarter of the laptop screen. Again, these were icons. I tried to replicate that after I obviously screwed things up. If someone could help. I would appreciate it. If I have to use terminal, that's fine. I started using computers for writing back when they were green DOS prompts. There's a certain elegance to prompt commands to me. Maybe it's the writer in me. Again, if anyone can help me return my screens to sync under Ubuntu 11.10, I would greatly appreciate it.

  • Mouse selects everything on its own

    - by meneer
    I have a strange problem that my mouse keeps selecting everything I point to. For example, if I open Rhythmbox, then at the top of the screen there is a text which says which song is playing. If I move my mouse over this text, then it will select this text; but I am not clicking. This behaviour does not happen in all programs. For example in Firefox I have no problem at all. Maybe it is Gtk related? Nautilus also behaves strangely; I cannot open files by clicking on them, I have to select and make a box around the file and then press enter to open it. If I click, then nothing happens. Similar problems also happen with other Gtk software. I think the problem might be related to touchscreen issues (I have a touchscreen). I run Gnome 3 on Ubuntu 12.04. I have a HP touchsmart 610 desktop computer. Any help is greatly appreciated. UPDATE: I just did a fresh reinstall, and I am 90% certain that it is related to the touchscreen drivers. Here is what happens when I reinstall. At first boot, so exactly after install, everything works fine, except the touchscreen: The touchscreen does not respond. I update ubuntu, because I installed from an old CD (CD with ub. 12.04). Then on next reboot I have touchscreen working , but the working touchscreen comes together with the mouse selecting everything on its own. SECOND QUESTION: Would anybody know how I could figure out what those touchscreen drivers are (so that I can disable them) ?

  • Windows Phone 7 v. Windows 8 Metro &ldquo;Same but Different&rdquo;

    - by ryanabr
    I have been doing development on both the Windows Phone 7 and Windows 8 Metro style applications over the past month and have really been enjoying doing both. What is great is that Silverlight is used for both development platforms. What is frustrating is the "Same but Different" nature of both platforms. Many similar services and ways of doing things are available on both platforms, but the objects, namespaces, and ways of handling certain cases are different. I almost had a heart attack when I thought that XmlDocument had been removed from the new WinRT. I was relived (but a little annoyed)  when I found out that it had shifted from the "System.Xml" namespace to the "Windows.Data.Xml.Dom" namespace. In my opinion this is worse than deprecating and reintroducing it since there isn't the lead time to know that the change is coming, maker changes and adjust. I also think the breaks the compatibility that is advertised between the WinRT and .NET framework from a programming perspective, as the code base will have to be physically different if compiled for one platform versus the other. Which brings up another issue, the need for separate DLLs with for the different platforms that contain the same C# code behind them which seems like the beginning of a code maintenance headache. Historically, I have kept source files "co-located" with the projects that they are compiled into. After doing some research, I think I will end up keeping "common" files that need to be compiled in to DLLs for the different platforms in a seperate location in TFS, not directly included in any one Visual Studio project, but added as links in the project that would get compiled into the windows 7 phone, or Windows 8. This will work fine, except for the case where dependencies don't line up for each platform as described above, but will work fine for base classes that do the raw work at the most basic programming level.

  • How do i reinstall windows back on to linux without flashdrive or cd?

    - by user287536
    I know this is for ubuntu. but elementary os and ubuntu are really similar, so any answers or instructions will work on this os. plus the people here at ubuntu are alot better with these kind of problems. I've installed elementary os, and i am somewhat satisfied. However, many of the addons and applications i used to use are incompatible with linux and wine doesnt work with these apps that work with drivers and plugins. My recovery hp partition was replaced by the grub partition somehow. i dont' have a cd or a working flashdrive. i have found many links, but i dont understand the instructions to a full level. ive heard that you can create a partition, extract your windows iso there, and then boot from it. i have done the first 2 steps, but i dont know how to boot from a certain partition. i know how to with command prompt, but not with terminal and/or grub. Please help? im a noob in linux, ive only installed it for a month

  • batch: comparing filenames and renaming [migrated]

    - by user2978770
    i'm new to both this platform and batch programming and i'm slowly but steadily driving crazy :-( I'm studying in Germany and just started on a bigger project that mainly consists of analyzing data and finding algorithms in order to maintain a certain function of a system. In order to get started i got a bunch of recorded data that, unfortunately, is not consistent when i comes to naming. Normally all files (all in one folder) should start with SPY.SPYNODE.SIDE and then go on with the specific names for each values or variables. However, the data logger messed it up a couple of times and gives weird names like SP0E1A~1.csv (all files are .csv-files). An that's when i figured in stead of renaming a couple of thousand files manually i could "easily" use a simple batch file to do that job for name. And that's exactly when I started to go crazy :-) So far i came up with the following: FOR /R %%i in (%CD%) DO ( set file1=%%i if not %file1%=="SPY.SPYNODE.SIDE" DO ( set /p "filename" < %file1% rename %file1% %filename% ) ) So what i want it to do is this (in pseudo) look through the whole folder and every file save the filename in variable file1 if file1 partially equals SPY.SPYNODE.SIDE open the file and save the first line (which contains the correct name of the file) in variable filename rename the file with the correct filename But so far it doesn't really work and i don't know why. Could anybody give me a hint or some advice how i should proceed? I really appreciate any kind of help!

  • How to progress far enough in a year [on hold]

    - by xCasper
    So I came to a realization the other day, I graduate in a year. I will have completed my four year degree in about two and a half (I went to a school that goes full time year round). Anyway, I want to get a job, as a programmer, when I graduate. The problem is, I feel like I am no where near ready. In the last year I cant say I have made any spectacular projects. I know that my advanced programming courses are coming up, but by the time I take them, I will be graduating in 6 months. Not nearly enough time to really take what I learn, apply it, and create something to show for myself. I want to push myself ahead of the game; mainly because my major is Computer Information Systems, so the focus is not programming. In fact, I only get, 4 programming classes. Before anyone says anything, CIS is the closest to a programming major at my school that I am able to do. So the questions come down to this: 1) What can I do to really step up the speed at which I progress (on my own) 2) Should I be aiming for a certain amount of projects in my "Portfolio." 2a) Should they be big projects? P.S: The language we have used in school in c++, I do take a Java class in the spring, and .net over Summer; if any of that matters for anything.

  • Making HTML5 videos stored on AWS S3 **difficult** to download (because I cant make it impossible)

    - by Jimmery
    I am building a website that hosts video's stored on AWS's S3 service. The videos are played thru a HTML5 player we have built. Ive just been asked to make sure "nobody can steal our video's". Now I know that if you really don't want something stolen, don't put it up on the internet. However I just need to secure these videos as good as possible, the videos need to at the very least resist someone going thru the source code and trying to download them manually. One option available to me is to completely rebuild the video player in flash. This is not ideal, for several reasons, notably because I would also then have to build an App for mobile devices to be able to view this site. So I am looking for other options. I have heard about using a token to make the file available only during certain times. I have heard of using a separate file to serve the videos that sits between the HTML5 page and the video file. I am also having a look at IAM, the Secure AWS Access Control, in the hopes AWS can solve this problem for me. Can anyone here recommend any of these options? Or perhaps suggest other options available to me? Any help would be greatly appreciated.

  • Iptables working strangely

    I have Ubuntu 12.04 x64 installed in my laptop. I'm quite new to linux, and I wanted to specify certain rules for the iptables firewall. This is the saved config of my iptables: *mangle :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] COMMIT *nat :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A PREROUTING -p tcp -m tcp --dport 3306 -j DNAT --to-destination 192.168.1.100:3306 -A PREROUTING -p tcp -m tcp --dport 11002 -j DNAT --to-destination 192.168.1.100:11002 -A PREROUTING -p tcp -m tcp --dport 13000 -j DNAT --to-destination 192.168.1.100:13000 -A PREROUTING -p tcp -m tcp --dport 13001 -j DNAT --to-destination 192.168.1.100:13001 -A PREROUTING -p tcp -m tcp --dport 13002 -j DNAT --to-destination 192.168.1.100:13002 -A PREROUTING -p tcp -m tcp --dport 13003 -j DNAT --to-destination 192.168.1.100:13003 -A PREROUTING -p tcp -m tcp --dport 13004 -j DNAT --to-destination 192.168.1.100:13004 -A PREROUTING -p tcp -m tcp --dport 13061 -j DNAT --to-destination 192.168.1.100:13061 -A PREROUTING -p tcp -m tcp --dport 13099 -j DNAT --to-destination 192.168.1.100:13099 -A POSTROUTING -j MASQUERADE COMMIT *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT COMMIT In theory, what it does is to drop all connections in all ports except for http, mysql and few other ports. Moreover, it redirects all mysql and 13000-13004..etc port connections to a specific local ip in the same port, which is 192.168.1.100. But what I find strange is that when my firewall is active, it blocks absolutely all the input connections, even those which must not block (http, mysql). In fact, I'm literally blocked and I can't establish any external connection. What am I doing wrong? PS: I tested the firewall without those redirections, and it still block all inputs, so I suppose it's not the problem.

  • To program in free time as a programmer, is to show that programming is passion. If not, is the programmer good? [closed]

    - by SonofWatson
    Possible Duplicate: I don't program in my spare time. Does that make me a bad developer? A lot of blogs and advice on the web seem to suggest that in order to become a great developer, doing just your day job is not enough. For example, you should contribute to open source projects in your spare time, write smartphone apps, etc. In fact a lot of this advice seems to suggest that if you don't love programming enough to do it all day long then you're probably in the wrong career. That doesn't ring true with me. I enjoy my work, but when I come home from the office I'm not in the mood to jump straight back onto the computer and start coding away until bedtime. I only have a certain number of hours free time each day, and I'd rather spend them on other hobbies, seeing friends or going outside than in front of the computer. I do get a kick out of programming, and do hack around outside of work occasionally. I'm committed to my personal development and spend time reading tech blogs and books as a way to keep learning and becoming better. But that doesn't extend so far as to my wanting to use all my spare time for coding. Does this mean I'm not a 'true' software developer at heart? Is it possible to become a good software developer without doing extra outside your job? I'd be very interested to hear what you think.

  • How and what should I be (unit) testing for in this method?

    - by user460667
    I am relatively new to unit testing and have a query about what/how I should be testing a certain method. For the following (psudo-c#) method I have created (not a real-life example) what would you test for? Initially, my thoughts would be to test the output with variations on the dictionary of form fields, e.g. valid, invalid, missing values. However I also wonder how you would test to make sure the object values have been changed to the correct value and that the correct email message was attempted to be sent (obviously both services could/would be mocked). I hope what I am asking makes sense, I appreciate this is a subjective question and the answers may be 'it depends' ;) public bool ProcessInput(Dictionary<string, string> formFields, ObjService objService, EmailService emailService) { try { // Get my object id int objId; if(!int.TryParse(formField["objId"], out objId) { return false; } // Update my object - would you validate the save against a DB or a mocked inmemory db? var myObj = objService.Find(objId); myObj.Name = formField["objName"]; objService.Save(myObj); // Send an email - how would you test to make sure content, recipient, etc was correct? emailService.SendEmail(formField("email"), "Hello World"); return true; } catch(Exception ex) { return false; } }
