  • Should I avoid or embrace asking questions of other developers on the job?

    - by T.K.
    As a CS undergraduate, the people around me are either learning or are paid to teach me, but as a software developer, the people around me have tasks of their own. They aren't paid to teach me, and conversely, I am paid to contribute. When I first started working as a software developer co-op, I was introduced to a huge code base written in a language I had never used before. I had plenty of questions, but didn't want to bother my co-workers with all of them - it wasted their time and hurt my pride. Instead, I spent a lot of time bouncing between IDE and browser, trying to make sense of what had already been written and differentiate between expected behavior and symptoms of bugs. I'd ask my co-workers when I felt that the root of my lack of understanding was an in-house concept that I wouldn't find on the internet, but aside from that, I tried to confine my questions to lunch hours. Naturally, there were occasions where I wasted time trying to understand something in code on the internet that had, at its heart, an in-house concept, but overall, I felt I was productive enough during my first semester, contributing about as much as one could expect and gaining a pretty decent understanding of large parts of the product. I was wondering what senior developers felt about that mindset. Should new developers ask more questions to get to speed faster, or should they do their own research for themselves? I see benefits to both mindsets, and anticipate a large variety of responses, but I figure new developers might appreciate your answers without thinking to ask this question.

  • Are there any significant advantages to using a native language for mobile app development?

    - by Karl Daniel
    Forgive me if this question has already been answered but I couldn't quite find the answer I was looking for. What I wanted to know was, is there any significant advantage to using a native language when developing and deploying apps to a mobile environment? The reason I ask is for a long while now I've been using Objective-C, Apple's native language for iOS, to build my apps. However I've been wondering whether or not there is any real benefit to doing this, over using a non-native language like JavaScript and then deploying it through a service like 'Phone Gap'? I do stress 'significant' advantages as native languages are always more likely to have the upper hand when it comes to speed and access to the latest APIs. However in general I don't see using a non-native language or a service like 'Phone Gap' causing and major slow down to my apps or restricting my development. Additionally having the ability to deploy to multiple services is also very handy indeed. This is why I put the question, are there any significant advantages to using a native language for mobile app development?

  • How do I fix a terrible system error on ubuntu 12.04

    - by Anonymous
    I don't know what happened, but one day my computer had some sort of a system error and could no longer update itself. The software center will not open, it will begin to initialize and then a message pops up saying theres a system error and needs to shut down the software center. Then another box pops up after I go to report it saying it was unable to identify source or package name. I also can't extract a zipped folder to anything, or reinstall Ubuntu from a USB boot drive anymore, it keeps telling me my my computer isn't compatible when I know for a fact it is, because thats how I got Ubuntu on here in the first place. the only thing I know about this error is that a message popped up after I went to check for updates saying to report the problem and include this message in the report: 'E:malformed line 56 in source list /etc/apt/sources.list (dist parse)' it also called it a bug. I just want to know how to either get rid of the bug completely or find some way to be able to reinstall Ubuntu again. I know it's not a lot of information, but It's all I can give. Sorry.

  • TraceTune: Improved Comment View

    - by Bill Graziano
    I wanted an easier way to identify queries I’d already looked at so I could skip them.  I’ve been entering comments for each query as I review it.  These comments typically fall into three categories: a change I made, no easy fix available or something needs to be changed on the client.  TraceTune now highlights any statement with a comment in bold.  If you hover over the statement you’ll see the most recent comment for that statement. This gives me a quick way to see what’s new and identify those queries that still need work.  This is especially helpful when I come back to a server after weeks or months away.  These comments help jar my memory and remind me what I’ve worked on. I made the font slightly smaller in some of the tables.  It’s still readable but I’m able to get more of a SQL statement on the screen.  I also got to re-experience the pain of Internet Explorer, Chrome and FireFox all displaying text (and pop-up text) slightly different. Seeing the comments on a trace has been a big help to me.  I often do a round of tuning and then don’t come back to a server until months later.  Having the comments available helps me get back up to speed quickly.

  • game play strategy in an arena

    - by joulesm
    I am writing a player's behavior for an arena game, and I'm wondering if you can offer some strategies. I'm writing it in Python, but I'm just interested in the high level game play. Here are the game aspects: Arena is a circle of a given size. The arena size shrinks every round to help break ties. Players are much smaller circles, can be on teams of 1 or 2 players. Players attack by colliding with other players, and based on the physics of the collision (speed of both players, angle), one could force another player out of the arena. Once a player is out of the arena, they are out of the game (for that round). The goal is to be the only team with players left in the arena. All other players have been pushed (through collisions or mistakes) out of the arena. It is possible for there to be no winner if the last two players exit the arena at the same time. Once the player has been programmed, the game just runs. There is no human intervention in the game. I'm thinking it's easiest to implement a few simple programmatic rules for my player to follow. For example, stay close to center of the arena, attack opponents from the inner side of the arena, etc. Are there any good simple game strategies? Would adding a random aspect to the game help? For example, to avoid predictability by the other team or something. Thanks in advance.

  • Cannot view, use, or open CDs or DVDs in Ubuntu 12.04

    - by user67592
    I am fairly new to Ubuntu 12.04 and I have encountered a rather irritating problem. Whenever I insert a CD or DVD (whether it have data, music, movies, or nothing at all), nothing pops up saying "you have inserted a CD", "play with Rhythmbox?" etc. It doesn't show the CD in the launcher/dock or anything of the sort. This is especially peculiar because not only do I have a standard IDE built-in optical drive, but I have an external USB optical drive. Neither work. In addition, whenever I go to "Computer///" and I click (double click, right click, or even left click) on "CD/DVD Drive" nothing happens, when I right click and select "Open" nothing happens either [for either of the two drives (both are listed in Computer///)] And if I insert a blank disk and go to a disk burning program such as Brasero, and try to burn to the drive it detects no CDs or DVDs of any kind. I'm rather stumped and can't seem to find a question similar to this. :( Thanks for all your help in advance!! :) ~Preston Output of sudo lshw *-cdrom description: DVD-RAM writer product: CD/DVDW TS-H652M vendor: TSSTcorp physical id: 0.0.0 bus info: scsi@5:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0414 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc *-cdrom description: DVD reader product: DVD Writer 300n vendor: HP physical id: 0.0.0 bus info: scsi@4:0.0.0 logical name: /dev/cdrom2 logical name: /dev/cdrw2 logical name: /dev/dvd2 logical name: /dev/sr1 version: 1.25 serial: [ capabilities: removable audio cd-r cd-rw dvd configuration: status=nodisc

  • Including Microsoft.XNA.Framework.Input.Touch in a project?

    - by steven_desu
    So after running through tutorials by both Microsoft and www.xnadevelopment.com I feel very confident in my ability to get to work on my first game using the XNA Framework. I've manipulated sprites, added audio, changed game states, and even went a step further to apply the knowledge I had and figure out how to make animations and basic 2-dimensional physics (including impulses, force, acceleration, and speed calculations) But then shortly into the project I hit a curious bump that I've been unable to figure out. In wanting to implement menus, pause screens, and several different aspects of play (a "pre-level" prep screen, the level itself, and a screen after the level to review how well you did) I took a look at Microsoft's Game State Management sample. I understood the concept, although it was admittedly quite a lot to take in. Not wanting to recreate the entire concept by scratch (after all- what purpose would that serve?) I tried copying and pasting the sample code into my own ScreenManager class (as well as InputState and GameScreen classes) to try and borrow their ingenuity. When I did this, however, my project stopped compiling. I was getting the following error: The type or namespace name 'Touch' does not exist in the namespace 'Microsoft.Xna.Framework.Input' (are you missing an assembly reference?) Having read through their sample code already, I realized that this namespace and every function and class within it could be safely ripped from the code without losing functionality. It's a namespace simply for integrating with touchscreen devices (presumably Windows Phone 7, but maybe also tablets). But then I began to wonder- how come Microsoft's sample compiled but mine didn't? I copied their code exactly so there must be a setting somewhere that I need to change in Visual Studio in order to correct this. I tried creating a new project as a Windows Phone 7 game rather than a Windows game, however that only forced it to compile to a Windows Phone emulator and denied me the ability to change the resolution and other features which I clearly had the power to do in the sample code. So my question is simple - how do I properly use the namespace Microsoft.XNA.Framework.Input.Touch?

  • Multitouch screen not detected on Asus Taichi 21DH71

    - by geekfreak
    I just bought this Ultrabook "Asus Taichi 21 DH71". This has Intel 3rd generation i7 processor and 4gb ram with 256 gb SSD. The main feature is that it is a hybrid machine. Naming it has dual screens. When the lid is closed it can be used as a tablet and when lid open it can be used as a notebook. This machine can also be used with the two screens on at the same time. I used ubuntu many years ago and loved it. But I never tried any linux later. My questions are Does the new version of Ubuntu support the Multitouch interface? Will it work specifically on this machine? Will Ubuntu support gestures on multi touchpad? Update 2/22/2013 I did try the latest 64bit Ubuntu(12.10) from live usb and noticed that it couldn't detect the tablet screen. Everything else worked seamlessly. Do you guys think the tablet screen would be detected if I make a complete installation on to the notebook? Please help guys..

  • Macbook overheats in 12.04 beta

    - by zookalicious
    Since I've heard a lot of great things about the upcoming 12.04 release, I decided to give the beta 2 a shot. Everything works very well, except ubuntu wasn't controlling the fan speed for a while. In all the past versions of ubuntu, I've just used the mactel support repository to detect my fans with the macfanctld package, and that has worked well. However it doesn't seem like that package has been updated yet for Precise, so I used the method at this Ubuntu forums thread instead. Now my computers fans are recognized and will spin up, but my laptop is getting VERY hot very frequently. Even just opening up a web browser and Libreoffice writer is enough to make the bottom of my computer feel like it's on fire and cause the fans to spin up to full. "top" shows that there are no programs eating up my CPU usage, which sometimes causes overheating. If anyone has any suggestions I would love to hear them. 12.04 is very nice and I know that for 11.10 macfanctld didn't get updated for a long time, so I'm hesitant to just wait for that.

  • Install Ubuntu on Asus Eee-PC 1005PE - Dealing with special partitions

    - by MestreLion
    I have an Asus EeePC 1005PE netbook and im planning on doing a massive re-partitioning (going to install Ubuntu, Mint, XP, etc) Ive noticed it has 2 "special" partitions: a 10Gb Fat32 RESTORE hidden partition (used by BIOS "F9 recovery" feature) and a 16Mb "unknown" partition at the end of the drive (used by BIOS "Boot Booster" feature). So, for both partitions, my question is: Can I move/resize the recovery partition freely? What are the requirements for it? (i mean, for it still be found by BIOS when i press F9/Activate BootBooster?). Partition table order? Partition type? Flags? Label? UUID? Can i make it a Logical (instead of primary) partition? Does it must be the flagged as boot? And, more importantly: where can i find any official documentation about it? Ive ready many (mis)information about it... some say Boot Booster partition must be last (in partition table), some say Recovery must be 2nd, that it must be bootable, etc. How can I know what is really needed for the BIOS to use both F9 and Boot Booster? Note: Im using gParted from a Live USB Stick (Mint 10 / Ubuntu 10.10), and ive noticed that, since the filesystem type of the Boot Booster is not recongnized, it cant move or resize it. Can I delete it and re-create it somewhere else? Whenever i create a 0xEF partition gParted crashes and quits and i cannot open it again (must delete the partition using fdisk / cfdisk)

  • My wireless has suddenly became disabled by hardware switch, BIOS, rfkill, fn+f8 do nothing

    - by cwwk
    I have a toshiba l655d-s5145. There is no physical toggle for the wireless, although the f8 key is supposed to do the trick. It doesn't. The wireless has been working since October, and suddenly, nothing. RFKILL reports that the wireless is hard blocked, but unblock wifi, unblock 0, unblock all do nothing. I inserted a usb dongle, and that is also disabled by hardware switch, although rfkill reports that it is neither hard nor soft blocked. My onboard wireless is 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01) according to lspci. Lsmod reports that these drivers are loaded. rtl8192c_common 75767 1 rtl8192ce rtlwifi 110972 1 rtl8192ce I resorted to reformatting the drive and reinstalling, but that also did not work. In BIOS I restored system defaults as there is no specific entry for wifi. Before reinstalling a pure xubuntu I went into Unity and saw that the airplane mode was on and despite being toggled off, it returned to the on position. I'm not sure where to find airplane mode in Xubuntu. What else can I do? I need my wireless.

  • X won't start, root filesystem mounted read only

    - by TK Kocheran
    I just experienced a very strange and puzzling problem on my machine that I can't seem to get sorted out. I was running Windows on a second partition, and everything was working great. I then went to restart into Linux, and noticed that X wouldn't start. Everything was displayed in super-low resolution, so I tried reinstalling my NVIDIA driver. I started seeing all of these I/O error problems, so I figured that my SSD was bad. After a bit more playing around, I ran fsck on the drive when mounted from a startup disk as well as badsectors and everything looked great. The SMART drive tests all passed and again, everything was looking good, so I rebooted again and still, no joy. I started then getting some weird USB errors, so I followed someone's advice and unplugged my computer's power supply, then started back up again and my graphics looked a lot better in the BIOS and in the boot logo, but X still wouldn't start. I then found out that my main boot drive was being mounted read-only for some reason. What's going wrong? I've done some pretty extensive tests on the SSD from a startup disk such as writing massive files, reading big files, running filesystem checks on the entire disk, and everything is looking great, until I try to boot. Whenever I try installing the drivers with apt-get, I get a ton of ata error messages looking like this: How can I diagnose what's going wrong and fix it so I can get back to work?

  • 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?

  • On Screen Coin Animation

    - by Siddharth
    am working with side scrolling skater game. I want to perform coin animation such that as player collect coin it moves upside and attach with currency sprite. My main character and coin present in game scene and currency sprite present in HUD layer. This situation creates problem for me. Directly I can not apply modifier to coin because it is side scrolling game so based on main character speed it reaches at different position. That I have checked. So that I have to generate other coin at same position at game layer coin has, in HUD layer and move upward to it. But I didn't able to get its y position correct though I can able to get x position correctly. Many time main character goes downward so it get minus value many time. I also tried following code float[] position = GameHUD.this .convertSceneCoordinatesToLocalCoordinates(GameManager .getInstance().getCoinX(), GameManager.getInstance() .getCoinY()); But I am getting same coordinate as I provide. No difference in that so please some one provide me guidance in that. Because I am near to complete my game. EDIT: Here game layer and hud layer is totally different. Actual coin present in game layer which player has to collect and at same position I want to generate another coin in hud layer to perform some animation. It is recommended to generate coin in hud layer because through that only I can able to complete my target.

  • Need Help Hiring a Perfectionist Programmer [closed]

    - by Bryan Hadaway
    I understand my question may be in the gray area, but I'm not able to use the Meta to ask if this question is appropriate or not so I'll simply have to risk it. My project is complete in the sense that it's a fully functional, ready to go 1.0 version. However, that's not good enough for my standards. My expertise is in HTML/CSS, not jQuery and PHP. I'm looking for someone to refine every character of my code for quality, speed, security and compatibility. I want everything to be as bug free as possible for launch. So I need an expert programmer who's a perfectionist in their coding who cares about the quality of their work (not just making it work) to review and refine my code. I'm sure I can't outright post the project's details and hope for interested parties to contact me as that wouldn't be beneficial to the community so instead I'm looking for advice from programmers about where some of best places to hire quality programmers are and the best strategies to hire the right programmer. In other words, screening applicants off of craigslist isn't going to cut it for this project. Thanks

  • Faster 2D Collision detection

    - by eShredder
    Recently I've been working on a fast-paced 2d shooter and I came across a mighty problem. Collision detection. Sure, it is working, but it is very slow. My goal is: Have lots of enemies on screen and have them to not touch each other. All of the enemies are chasing the player entity. Most of them have the same speed so sooner or later they all end up taking the same space while chasing the player. This really drops the fun factor since, for the player, it looks like you are being chased by one enemy only. To prevent them to take the same space I added a collision detection (a very basic 2D detection, the only method I know of) which is. Enemy class update method Loop through all enemies (continue; if the loop points at this object) If enemy object intersects with this object Push enemy object away from this enemy object This works fine. As long as I only have <200 enemy entities that is. When I get closer to 300-350 enemy entities my frame rate begins to drop heavily. First I thought it was bad rendering so I removed their draw call. This did not help at all so of course I realised it was the update method. The only heavy part in their update method is this each-enemy-loops-through-every-enemy part. When I get closer to 300 enemies the game does a 90000 (300x300) step itteration. My my~ I'm sure there must be another way to aproach this collision detection. Though I have no idea how. The pages I find is about how to actually do the collision between two objects or how to check collision between an object and a tile. I already know those two things. tl;dr? How do I aproach collision detection between LOTS of entities? Quick edit: If it is to any help, I'm using C# XNA.

  • How can I remove unmounted SD Card icons from my desktop?

    - by user75286
    I have been using some audio utilities in Ubuntu 11.10 to tweak .mp3 files on my phone (Motorola Photon 4G). I connect via USB... both my phone and the internal SD card are mounted as two separate drives. The SD card has an unusual drive name with some odd characters. When I'm finished, I unmount my phone (or "safely remove drive"), but the SD card can't be unmounted. I've mounted and unmounted my phone on 4 occasions now, and there are now 4 SD card drive icons that I can't remove from the desktop. I tried using the gconf-editor/apps/nautilus/desktop trick to make drives invisible and it's not working. Right-clicking on the icons and selecting "unmount" produced the following error message; (I can't type the unusual drive name characters... replaced with xxx) Unable to unmount xxx umount: /media/xxx is not mounted (according to mtab) How can I remove the unwanted icons from the desktop and is there a method for avoiding this problem in the future? Thanks!

  • Pair Programming, for or against? [on hold]

    - by user1037729
    I believe it has many advantages over individual programming: Pros By pairing senior with relatively junior staff, the more junior can get up to speed with both project and computing experience, and the senior will re-think the problem in order to communicate with the junior, thus re-checking his own thinking (rubber duck principle!). At least 2 people will know about any single piece of work, if one person is away the other can cover, or if some one leaves a project knowledge transfer is easier. Two brains on a complex task is more effective, communication keeps the work free flowing and provides redundancy in decision making. Code is effectively reviewed as its being written, no need for a separate reviewing phase which requires a context switch as someone who has not been working on the piece in question would be required to understand and review the related code. Reviewing code on your own which you haven't written or architected is not fun, hence counter productive. Cons Less bandwith for performing tasks, lets say we have 4 devs, pair programming requires 2 devs per task, so we would be doing 2 tasks concurrently as a posed to 4. I believe this "Con" does not stand up as the pair programmed task would complete sooner and comes with a review built in for free! Ie the pair programming task would be more efficient and thus free up resources earlier. Less flexibility to chop and change tasks as two developers are tied into a task, when flexibility is required this could be a problem.

  • OSB, Service Callouts and OQL

    - by Sabha
    Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This series will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. The second section of the "OSB, Service Callouts and OQL" blog posting will delve into thread dump analysis of OSB server and detecting threading issues relating to Service Callout and using Heap Dump and OQL to identify the related Proxies and Business services involved. The final section of the series will focus on the corrective action to avoid Service Callout related OSB serer hangs. Before we dive into the solution, we need to briefly discus about Work Managers in WLS. Please refer to the blog posting for more details.

  • Is this a ridiculous way to structure a DB schema, or am I completely missing something?

    - by Jim
    I have done a fair bit of work with relational databases, and think I understand the basic concepts of good schema design pretty well. I recently was tasked with taking over a project where the DB was designed by a highly-paid consultant. Please let me know if my gut intinct - "WTF??!?" - is warranted, or is this guy such a genius that he's operating out of my realm? DB in question is an in-house app used to enter requests from employees. Just looking at a small section of it, you have information on the users, and information on the request being made. I would design this like so: User table: UserID (primary Key, indexed, no dupes) FirstName LastName Department Request table RequestID (primary Key, indexed, no dupes) <...> various data fields containing request details UserID -- foreign key associated with User table Simple, right? Consultant designed it like this (with sample data): UsersTable UserID FirstName LastName 234 John Doe 516 Jane Doe 123 Foo Bar DepartmentsTable DepartmentID Name 1 Sales 2 HR 3 IT UserDepartmentTable UserDepartmentID UserID Department 1 234 2 2 516 2 3 123 1 RequestTable RequestID UserID <...> 1 516 blah 2 516 blah 3 234 blah The entire database is constructed like this, with every piece of data encapsulated in its own table, with numeric IDs linking everything together. Apparently the consultant had read about OLAP and wanted the 'speed of integer lookups' He also has a large number of stored procedures to cross reference all of these tables. Is this valid design for a small to mid-sized SQL DB? Thanks for comments/answers...

  • cannot boot Ubuntu after fresh install

    - by Jonathan
    I just installed Ubuntu on a Lenovo v570, and cannot boot into the system. All I get is a loop, where some (bios) info is displayed, and then the computer asks me where I would like to boot from. I tried reinstalling, reinstalling with a custom partition scheme, and boot -repair after the install. None of these work. I can see the files on my harddisk have been copied. I have installed many Ubuntus in the past, as well other distros where custom partitioning is required. I don't know where to find any useful information since I don't even get too the grub menu. One odd thing I noticed. The bios now had options to boot USB, OpenSuse,Fedora, or the HD. I am not dual booting. I also realized that the boot info is for a network boot, which means the computer is not recognizing what to boot. It is boot an HD problem, because I can install other OSs just fine. I am completely stumped. I would like to settle this, and end up with a tutorial, that explains to me what happened.

  • How to host an AP or a hotspot?

    - by user1048138
    I'm running Ubuntu 12.04 as a virtual machine on my Mac. Since I am unable to get the virtual machine to have full access to my WiFi card, I bought another USB WiFi card to use. This is my WiFi card. If you are unfamiliar with Virtual machine, as far as I know, since the Ubuntu has its own card now, it shouldn't matter. I have followed these guides with no luck: https://help.ubuntu.com/community/WifiDocs/WirelessAccessPoint http://www.danbishop.org/2011/12/11/using-hostapd-to-add-wireless-access-point-capabilities-to-an-ubuntu-server/ The problem is that the WiFi connection appears on all of the machines that I have in my house: 2 iPhones, Dell machine running Ubuntu and two Macbooks. However the connection times out on all of these machines. Questions: Could this be a driver issue if that same WiFi card can connect to other WiFi points and use its internet Could this be DHCP related? I would think not. It should at least get a 169.X.X.X address? No? Any solutions for me?

Stop.' I am lost. Any help would be appreciated.
