• Information I need to know as a Java Developer [on hold]

  - by Woy

  I'm a java developer. I'm trying to get more knowledge to become a better programmer. I've listed a number of technologies to learn. Instead of what I've listed, what technologies would you suggest to learn as well for a Junior Java Developer? I realize, there's a lot of things to study. Java: - how a garbage collector works - resource management - network programming - TCP/IP HTTP - transactions, - consistency: interfaces, classes collections, hash codes, algorithms, comp. complexity concurrent programming: synchronizing, semafores steam management metability: thread-safety byte code manipulations, reflections, Aspect-Oriented Programming as base to understand frameworks such as Spring etc. Web stack: servlets, filters, socket programming Libraries: JDK, GWT, Apache Commons, Joda-Time, Dependency Injections: Spring, Nano Tools: IDE: very good knowledge - debugger - profiler - web analyzers: Wireshark, firebugs - unit testing SQL/Databases: Basics SELECTing columns from a table Aggregates Part 1: COUNT, SUM, MAX/MIN Aggregates Part 2: DISTINCT, GROUP BY, HAVING + Intermediate JOINs, ANSI-89 and ANSI-92 syntax + UNION vs UNION ALL x NULL handling: COALESCE & Native NULL handling Subqueries: IN, EXISTS, and inline views Subqueries: Correlated ITH syntax: Subquery Factoring/CTE Views Advanced Topics Functions, Stored Procedures, Packages Pivoting data: CASE & PIVOT syntax Hierarchical Queries Cursors: Implicit and Explicit Triggers Dynamic SQL Materialized Views Query Optimization: Indexes Query Optimization: Explain Plans Query Optimization: Profiling Data Modelling: Normal Forms, 1 through 3 Data Modelling: Primary & Foreign Keys Data Modelling: Table Constraints Data Modelling: Link/Corrollary Tables Full Text Searching XML Isolation Levels Entity Relationship Diagrams (ERDs), Logical and Physical Transactions: COMMIT, ROLLBACK, Error Handling

• Partitions for dual boot install with Windows

  - by Tim

  Following is the layout of the current partitions of my single hard drive viewed from Windows 7: C: has Windows 7 system files and my personal data; Q: for Lenovo recovery; SYSTEM_DRV: for Windows boot files; My goals are: to create another partition D: for my personal data, and dedicate C: for Windows system files and applications only. to install Ubuntu alongside Windows. D: will be shared between the two OSes. My questions are: Is it correct that the free space generated from shrinking C: will only be able to create an extended partition, since there are already 3 primary partitions? So must D: be one logical partition on the extended partition, just as the partitions for Ubuntu will be? Will this be bad sometime? If yes, other better solutions? What are the good utilities to accomplish the partition tasks? Can Ubuntu installer solely handle them? Or better to have some of the jobs done in Windows with some recommended softwares? Thanks and regards!

• Dual displays not working - NVidia - Ubuntu 12.04 - Second Monitor - Two Screens

  - by user75105

  Graphics Card: NVidia 460 GTX. Driver: NVIDIA accelerated graphics driver (version current) I have one DVI monitor, an old Dell LCD from 2005, and one VGA monitor, an Asus ML238H from 2010 whose HDMI port broke. The Asus is plugged into my graphics card's primary monitor slot and is the better monitor even though it is VGA but my computer defaults to the Dell. This happens when I boot as well; the loading screens, the motherboard brand image, etc. are all displayed on the Dell monitor until Windows loads. Then both monitors work. The same thing happened when I booted up Ubuntu 12.04 but I did not see the second monitor when the log-in screen popped up, nor did I when I logged in. I went to System Settings/Displays and my Asus monitor is not an option. I clicked Detect Displays and the Asus is not detected. I looked at the other questions regarding NVIDIA drivers and recalled my problems with Ubuntu a few years ago and decided to check the driver. I went to Additional Drivers to install the proprietary driver and it looks like it's installed and active but I'm still having this problem. There is another driver option, the post-release NVIDIA driver, but that does not fix the problem either. Also, under System Details/Graphics the graphics device is listed as Unknown, which might indicate that it is using an open source generic driver and not the proprietary NVidia driver. But under Additional Drivers it says that I am using the NVidia driver. Any help is appreciated.

• Is it okay to use a language that isn't supported by your company for some tasks?

  - by systempuntoout

  I work for a company that supports several languages: COBOL, VB6, C# and Java. I use those languages for my primary work, but I often find myself to coding some minor programs (e.g. scripts) in Python because I found it to be the best tool for that type of task. For example: An analyst gives me a complex CSV file to populate some DB tables, so I would use Python to parse it and create a DB script. What's the problem? The main problem I see is that a few parts of these quick & dirty scripts are slowly gaining importance and: My company does not support Python They're not version controlled (I back them up in another way) My coworkers do not know Python The analysts have even started referencing them in email ("launch the script that exports..."), so they are needed more often than I initially thought. I should add that these scripts are just utilities that are not part of the main project; they simply help to get trivial tasks done in less time. For my own small tasks they help a lot. In short, if I were a lottery winner to be in a accident, my coworkers would need to keep the project alive without those scripts; they would spend more time in fixing CSV errors by hand for example. Is this a common scenario? Am I doing something wrong? What should I do?

• From the Coalface - 3 - Work as hard as you can to be as lazy as you can!

  - by TATWORTH

  The saga of the Change Log A recent conversation reminded me of the need for change logs within a database, to record when various change scripts were run. Creating such the required table is simple. A typical table for this consists of: Id - identity Integer primary key ChangeFileName - NVARCHAR(128) to hold the name of the file run. DateAdded - DateTime non-null with default value of getutcdate() Purpose - NVARCHAR(128) Rerunnable - Bit non-null default 0. By good design of the table only two data values normally need to be supplied. Two stored procedures, one for inserting data and one to list in reverse sequence the log complete the database essentials. The complete implementation can be found in the CommonData solution at http://CommonData.CodePlex.Com By including a call the add Change Log stored procedure, each script can log its name and purpose for posterity. The scripts that were applied to say the UAT system and their sequence of application can be readily identified for running on the Live system. Formatting XML XML is often produced as one continous string with no embedded CR/LF. To get it into human readable form, open it in visual studio, swap to another tab and back and click the format document button. The XML will then be nicely formatted!

• What is involved with writing a lobby server?

  - by Kira

  So I'm writing a Chess matchmaking system based on a Lobby view with gaming rooms, general chat etc. So far I have a working prototype but I have big doubts regarding some things I did with the server. Writing a gaming lobby server is a new programming experience to me and so I don't have a clear nor precise programming model for it. I also couldn't find a paper that describes how it should work. I ordered "Java Network Programming 3rd edition" from Amazon and still waiting for shipment, hopefully I'll find some useful examples/information in this book. Meanwhile, I'd like to gather your opinions and see how you would handle some things so I can learn how to write a server correctly. Here are a few questions off the top of my head: (may be more will come) First, let's define what a server does. It's primary functionality is to hold TCP connections with clients, listen to the events they generate and dispatch them to the other players. But is there more to it than that? Should I use one thread per client? If so, 300 clients = 300 threads. Isn't that too much? What hardware is needed to support that? And how much bandwidth does a lobby consume then approx? What kind of data structure should be used to hold the clients' sockets? How do you protect it from concurrent modification (eg. a player enters or exists the lobby) when iterating through it to dispatch an event without hurting throughput? Is ConcurrentHashMap the correct answer here, or are there some techniques I should know? When a user enters the lobby, what mechanism would you use to transfer the state of the lobby to him? And while this is happening, where do the other events bubble up? Screenshot : http://imageshack.us/photo/my-images/695/sansrewyh.png/

• Kloxo - Use third party nameserver

  - by LePhleg

  Here's my case: I got my domain from a registrar. I got my VPS up from a provider who also offers free DNS hosting, on their own server (separately from my VPS, IP:111.111.111.111). So I got these third-party nameservers, lets name them: ns1.provider.com ns2.provider.com and pointed my domain registrar to them. I let it propagate for 24 hours so I believe its ok. (if I ping my domain I get the IP for these nameservers - 111.111.111.111) Afterwards I headed to my providers cPanel (the one they gave me for the DNS hosting service) and changed the default A Record IP from 111.111.111.111 to the IP associated with my VPS (IP:222.222.222.222). The last step, as I see it, is to configure my VPS via Kloxo panel and add the domain. Can someone guide me how can I achieve that? Is it just enough to create a new DNS Template and add as Primary DNS "ns1.provider.com" and Secondary DNS "ns2.provider.com"? Every tutorial I found is using Kloxo to create local nameservers on the same VPS which is something I want to avoid to save resources..

• How to make the internal subwoofer work on an Asus G73JW?

  - by CodyLoco

  I have an Asus G73JW laptop which has an internal subwoofer built-in. Currently, the system detects the internal speakers as a 2.0 system (or I can change do 4.0 is the only other option). I found a bug report here: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/673051 which discusses the bug and according to them a fix was sent upstream back at the end of 2010.

• Is full partition encryption the only sure way to make Ubuntu safe from external access?

  - by fred.bear

  (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

• Package Manager cannot access repositories but internet is working

  - by kazman

  I am currently at a conference in another country and my package manager cannot access repositories. My internet is working fine and I can ping the repositories or go to them in a browser, but package manager fails to access them. If I sudo apt-get update it throws Something wicked happened resolving 'wwwproxy:3128' (-5 - No address associated with hostname) (or Ign's). This proxy corresponds to my proxy at my office back at home, but I have disabled proxy in the package manager. Scanning for best repository doesn't work either, it doesn't manage to connect to any. I have searched for this online and have checked things about my apt.conf file. My apt.conf contains: Acquire::http::proxy "http://wwwproxy:3128/"; Acquire::https::proxy "https://wwwproxy:3128/"; Acquire::ftp::proxy "ftp://wwwproxy:3128/"; Acquire::socks::proxy "socks://wwwproxy:3128/"; If I remove apt.conf (or replace with blank), it makes no difference. I don't see that it should since I am connecting directly (and have set it so in my network options in Package manager network settings) I have also tried some things with resolv.conf (changing name address to primary and secondary dns) to no avail. (im not sure if this would help, following other advice) I am running 12.04. (I wrote this very quickly and wrote down everything I have tried to possibly shorten the troubleshooting process, have very limited time between lectures and need this sorted asap, my apologies)

• Can't load model using ContentTypeReader

  - by Xaosthetic

  I'm writing a game where I want to use ContentTypeReader. While loading my model like this: terrain = Content.Load<Model>("Text/terrain"); I get following error: Error loading "Text\terrain". Cannot find ContentTypeReader AdventureGame.World.HeightMapInfoReader,AdventureGame,Version=1.0.0.0,Culture=neutral. I've read that this kind of error can be caused by space's in assembly name so i've already removed them all but exception still occurs. This is my content class: [ContentTypeWriter] public class HeightMapInfoWriter : ContentTypeWriter<HeightmapInfo> { protected override void Write(ContentWriter output, HeightmapInfo value) { output.Write(value.getTerrainScale); output.Write(value.getHeight.GetLength(0)); output.Write(value.getHeight.GetLength(1)); foreach (float height in value.getHeight) { output.Write(height); } } public override string GetRuntimeType(TargetPlatform targetPlatform) { return "AdventureGame.World.Heightmap,AdventureGame,Version=1.0.0.0,Culture=neutral"; } public override string GetRuntimeReader(TargetPlatform targetPlatform) { return "AdventureGame.World.HeightMapInfoReader,AdventureGame,Version=1.0.0.0,Culture=neutral"; } } Does anyone meed that kind of error before?

• Do there exist programming languages where a variable can truly know its own name?

  - by Job

  In PHP and Python one can iterate over the local variables and, if there is only once choice where the value matches, you could say that you know what the variable's name is, but this does not always work. Machine code does not have variable names. C compiles to assembly and does not have any native reflection capabilities, so it would not know it's name. (Edit: per Anton's answer the pre-processor can know the variable's name). Do there exist programming languages where a variable would know it's name? It gets tricky if you do something like b = a and b does not become a copy of a but a reference to the same place. EDIT: Why in the world would you want this? I can think of one example: error checking that can survive automatic refactoring. Consider this C# snippet: private void CheckEnumStr(string paramName, string paramValue) { if (paramName != "pony" && paramName != "horse") { string exceptionMessage = String.Format( "Unexpected value '{0}' of the parameter named '{1}'.", paramValue, paramName); throw new ArgumentException(exceptionMessage); } } ... CheckEnumStr("a", a); // Var 'a' does not know its name - this will not survive naive auto-refactoring There are other libraries provided by Microsoft and others that allow to check for errors (sorry the names have escaped me). I have seen one library which with the help of closures/lambdas can accomplish error checking that can survive refactoring, but it does not feel idiomatic. This would be one reason why I might want a language where a variable knows its name.

• What is meant by "no password set" for root account (and otthers)?

  - by MMA

  Several years back, we were more accustomed to changing to the root account using the su command. First, we switched to the root account, and then executed those root commands. Now we are more accustomed to using the sudo command. But we know that the root account is there. We can readily find the home directory of user root. $ ls -ld /root/ drwx------ 18 root root 4096 Oct 22 17:21 /root/ Now my point is, it is stated that "the root password in Ubuntu is left unset". Please see the answers to this question. Most of the answers have something to this effect in the first paragraph. One or two answers further state that "the account is left disabled". Now my (primary) questions are, What is meant by an unset password? Is it blank? Is it null? Or something else more cryptic? How does the account becomes enabled once I set password for it? (sudo password root) In order get a better understanding, I checked the /etc/shadow file. Since I have already set a password for the root account, I can no longer see what is there (encrypted password). So, I created another account and left it disabled. The corresponding entry in the /etc/shadow file is, testpassword:!:16020:0:99999:7::: Now perhaps my above queries need to be changed to, what does an ! in password field mean? Other encrypted passwords are those very long cryptic strings. How come this encrypted form is only one character long? And does an account become disabled if I put an ! in the (encrypted) password field?

Or, is it possible to fix this by downloading the important packages in vista and moving them to ubuntu via USB drive?

• decouple software components via nameconvention

  - by csteinmueller

  I'm currently evaluating alternatives to refactor a drivermanagement. In my multitier architecture I have Baseclass DAL.Device //my entity Interfaces BL.IDriver //handles the dataprocessing between application and device BL.IDriverCreator //creates an IDriver from a Device BL.IDriverFactory //handles the driver creation requests Every specialization of Device has a corresponding IDriver implementation and a corresponding IDriverCreator implementation. At the moment the mapping is fix via a type check within the business layer / DriverFactory. That means every new driver needs a) changing code within the DriverFactory and b) referencing the new IDriver implementation / assembly. On a customers point of view that means, every new driver, used or not, needs a complex revalidation of their hardware environment, because it's a critical process. My first inspiration was to use a caliburn micro like nameconvention see Caliburn.Micro: Xaml Made Easy BL.RestDriver BL.RestDriverCreator DAL.RestDevice After receiving the RestDevicewithin the IDriverFactory I can load all driver dlls via reflection and do a namesplitting/comparing (extracting the xx from xxDriverCreator and xxDevice) Another idea would be a custom attribute (which also leads to comparing strings). My question: is that a good approach above layer borders? If not, what would be a good approach?

• Extremely slow desktop and laggy. Need help with graphics driver

  - by user171624

  I am a fresh newbie Ubuntu user and I just installed my first Ubuntu 13.04 onto my HP Slate 2. I did a liveCD on my USB drive and installed everything perfectly fine...nice and smooth, not a trace of lag. Then I rebooted using Ubuntu itself on the computer, it was extremely slow and laggy. Icons or any buttons doesn't trigger right away, the performance of the entire thing looks like either 0.25 fps to 1 fps. My HP Slate 2 information: Processor: Intel Atom Z670 1.5Ghz Memory Ram: 2.0 GB Videocard: Intel GMA 600 (PowerVr SGX535) SolidStateDrive(SSD): 32GB I tried installing the intel linux graphics driver and it failed to install because it said I don't have any intel based graphics card. Well...I do as you see above. What can I do? I can't get on the internet on it, I'm using my primary computer (Windows 7) to do all the searchings and put the files onto the USB to move it over to my tablet. Simply...I don't get it...using liveCD on USB, it was all nice and smooth...then after the installation...BOOM! Slow, laggy, and etc. Can anyone help me? Thanks!

• Store scores for players and produce a high score list

  - by zrvan

  This question is derived from an interview question that I got for a job I was declined. I have asked for code review for my solution at the dedicated Stack Exchange site. But I hope this question is sufficiently rephrased and asked with a different motivation not to be a duplicate of the other question. Consider the following scenario: You should store player scores in the server back end of a game. The server is written in Java. Every score should be registered, that is, one player may have any number of scores for any number of levels. A high score list should be produced with the fifteen top scores for a given level, but only one score per user (to the effect that even if player X has the two highest scores for level Y, only the first position is counted and player Z has the second place). No information should be persisted and only Java 1.7+ standard libraries should be used. No third party libraries or frameworks are acceptable. With the number of players as the primary factor, what would be the best data structure in terms of scalability and concurrency? How would you access the structure to register a single score given a level and a player id? How would you access the structure to compile the high score list?

• Localization of Database Strings in .Net

  - by Aligned

  I have several database tables that have a description column that I need to display in the UI. .Net has .resx files that will help with the translation of the strings, when the Thread.CurrentCulture.UICulture is set, but I needed a custom approach for the strings that are stored in the database and not in the .resx files. Here’s my approach: 1. Create a resource file for each database table and put them in the /Resources/Database/ directory. 2. Create a method in LocalizationHelpers (GetLocalizedString) that will get the string from the table for English (which should be cached to avoid unneeded service/database calls) or the resx when not English. 3. All database tables need to have a ResxKey field that matches the key in the resx file. 4. By convention the resx file will have the same name as the database table, and the key the same as the database ResxKey.   - if there are multiple columns that need translation, then one ResxKey will be used and Name or Description appended. Here’s the method I’m using to pull the string: public static string GetLocalizedString(string resourceName, string resourceKey) { if (executingAssembly == null) { executingAssembly = Assembly.GetExecutingAssembly(); } ResourceManager manager = new ResourceManager(resourceName, executingAssembly); return manager.GetString(resourceKey); }

• how to deal with controller mutations

  - by Milovan Zogovic

  During development process, things are constantly changing (especially in early phases). Requirements change, UI changes, everything changes. Pages that clearly belonged to specific controller, mutated to something completely different in the future. For example. Lets say that we have website for managing Projects. One page of the website was dedicated to managing existing, and inviting new members of specific project. Naturally, I created members controller nested under projects which had proper responsibility. Later in the development, it turned out that it was the only page that was "configuring the project" in some way, so additional functionalities were added to it: editing project description setting project as a default ... In other words, this page changed its primary responsibility from managing project members to managing project itself. Ideally, this page should be moved to "edit" action of "projects" controller. That would mean that all request and controller specs need to refactored too. Is it worth the effort? Should it be done? Personally, I am really starting to dislike the 1-1 relationship between views and controllers. Its common situation that we have 1 page (view) that handles 2 or more different resources. I think we should have views completely decoupled from controllers, but rails is giving us hard time to achieve this. I know that AJAX can be used to solve this issue, but I consider it an improvisation. Is there some other kind of architecture (other than MVC) that decouples views from controllers?

• What is the preferred pattern when attaching a 'runtime object'?

  - by sebf

  In my application I have the following: public class NeatObject { /* lots of static data, and configuration flags */ } public class NeatObjectConsumer { void DoCleverStuffWithObjectOnGPU(NeatObject obj); } Where NeatObject and its consumer are used to control the GPU. The idea being that, the configuration of an instance of NeatObject and its members, define how the consumer instance behaves. The object can be passed around, edited, and most importantly serialised/deserialised by the application, with and without knowledge of NeatObjectConsumer, then provided back to the consumer to do something else. The purpose of this seperation is: The consumer manages hardware resources, which change depending on the computer, and even on the execution of the application, making preserving the state of an object which does everything difficult. Avoids circular references if the assembly that contains the consumer needs to reference one that only needs to know about NeatObject. However, there is a complication in that the consumer creates hardware resources and needs to associate them with NeatObject. These don't need to be preserved, but still need to be retrieved. DoCleverStuffWithObjectOnGPU() will be called many, many times during execution and so any bottleneck is a concern, therefore I would like to avoid dictionary lookups. What is the preferred method of attaching this information to NeatObject? By preferred, I mean intuitive - other coders can see immediately what is going on - and robust - method doesn't invite playing with the resources or present them in such a way as to make them easily corruptible. Essentially, I want to add my own metadata - how should I do it? Try to use 'actual metadata' functionality like Reflection? A member of the type of an abstract class? Unmanaged pointers? If you took on a project that used this pattern, what would you have liked the previous developer to do?

• How to get the level and position of the player from an extern program? [on hold]

  - by user3727174

  I want to write a program that needs the current level and position of the player (primary single player). This should work for potentially every game installed and running on the computer my program is running on. The data I need is basically one integer value for the level (if there are any) and three integer values for x, y and optimal z for the position of the player. In which relation/scale or where the null point is does not matter, because this information is going to be interpreted game dependent, I will use this information to read information out of a database created for the game currently running. Currently I'm using C++, but if there is a better option for Java I´m willing to port my program. My thoughs so far are: make a mod for every game that should be supported, get the position/level from there, write this information to the disk and read it from my program tracking mouse/keyboard events and reconstructing the movement won't work Are there any general APIs for something like this? Any Tool to find this data? Or maybe engines that provide APIs to get this data directly from the game?

• What is the most effective approach to learn an unfamiliar complex program? [closed]

  - by bdroc

  Possible Duplicate: How do you dive into large code bases? I have quite a bit of experience with different programming languages and writing small and functional programs for a variety of purposes. My coding skills aren't what I have a problem with. In fact, I've written a decent web application from scratch for my startup. However, I have trouble jumping into unfamiliar applications. What's the most effective way to approach learning a new program's structure and/or architecture so that I can start attacking the code effectively? Are there useful tools for their respective languages (Python and Java are my two primary languages)? Should I be starting with just looking at function names or documentation? How do you veterans approach this problem? I find this has to be with minimal help from coworkers or contributors who are already familiar with the application and have better things to do than help me. I'd love to practice this skill in an open source project so any suggestions for starting points (maybe mildly complex) would be great too!

• What is the fastest way for me to become a full stack developer? [on hold]

  - by user136368

  I run a small webdesign firm. I have an overview of HTML, CSS, JS, PHP(laravel), MySQL. I did a few courses on code academy. I wanted to build a web app in the company. I find that I am severely crippled by the lack of programming expertise. I want to become a full stack developer who can build a prototype on his own. I cannot spend 5-10k USD on the boot camp courses. Can someone suggest structured courses which can help me become a full stack developers? I found the following websites but I donot know if they can help me become one. My goal: Be able to make a working prototype of the ideas I come up with.(This is my primary goal. I do not want to be the lead developer. I just want to be able to make a prototype.) Several questions I have in mind: Will it be fine if I stick to PHP(laravel)? Should I be using ROR? I have come across a few online resources: Codeacademy, codeschool,teamtreehouse,and theodinproject. These are within my affordability range. I can commit to a 2-3 months intensively to learn programming. What do you suggest I do?
