• How do I mount a CIFS share via FSTAB and give full RW to Guest

  - by Kendor

  I want to create a Public folder that has full RW access. The problem with my configuration is that Windows users have no issues as guests (they can RW and Delete), my Ubuntu client can't do the same. We can only write and read, but not create or delete. Here is the my smb.conf from my server: [global] workgroup = WORKGROUP netbios name = FILESERVER server string = TurnKey FileServer os level = 20 security = user map to guest = Bad Password passdb backend = tdbsam null passwords = yes admin users = root encrypt passwords = true obey pam restrictions = yes pam password change = yes unix password sync = yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . add user script = /usr/sbin/useradd -m '%u' -g users -G users delete user script = /usr/sbin/userdel -r '%u' add group script = /usr/sbin/groupadd '%g' delete group script = /usr/sbin/groupdel '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' guest account = nobody syslog = 0 log file = /var/log/samba/samba.log max log size = 1000 wins support = yes dns proxy = no socket options = TCP_NODELAY panic action = /usr/share/samba/panic-action %d [homes] comment = Home Directory browseable = no read only = no valid users = %S [storage] create mask = 0777 directory mask = 0777 browseable = yes comment = Public Share writeable = yes public = yes path = /srv/storage The following FSTAB entry doesn't yield full R/W access to the share. //192.168.0.5/storage /media/myname/TK-Public/ cifs rw 0 0 This doesn't work either //192.168.0.5/storage /media/myname/TK-Public/ cifs rw,guest,iocharset=utf8,file_mode=0777,dir_mode=0777,noperm 0 0 Using the following location in Nemo/Nautilus w/o the Share being mounted does work: smb://192.168.0.5/storage/ Extra info. I just noticed that if I copy a file to the share after mounting, my Ubuntu client immediately make "nobody" be the owner, and the group "no group" has read and write, with everyone else as read-only. What am I doing wrong?

• How to code Time Stop or Bullet Time in a game?

  - by David Miler

  I am developing a single-player RPG platformer in XNA 4.0. I would like to add an ability that would make the time "stop" or slow down, and have only the player character move at the original speed(similar to the Time Stop spell from the Baldur's Gate series). I am not looking for an exact implementation, rather some general ideas and design-patterns. EDIT: Thanks all for the great input. I have come up with the following solution public void Update(GameTime gameTime) { GameTime newGameTime = new GameTime(gameTime.TotalGameTime, new TimeSpan(gameTime.ElapsedGameTime.Ticks / DESIRED_TIME_MODIFIER)); gameTime = newGameTime; or something along these lines. This way I can set a different time for the player component and different for the rest. It certainly is not universal enough to work for a game where warping time like this would be a central element, but I hope it should work for this case. I kinda dislike the fact that it litters the main Update loop, but it certainly is the easiest way to implement it. I guess that is essentialy the same as tesselode suggested, so I'm going to give him the green tick :)

• Part 4: Development Standards or How to share

  - by volker.eckardt(at)oracle.com

  Although we usually introduce the custom development part in EBS projects as “a small piece only” and “we will avoid as best as possible”, the development effort can be enormous and should therefore be well addressed by project standards. Any additional solution or additional software tool or product shall influence the custom development rules (by adding, removing or replacing sections). It is very common in EBS projects to create a so called “MD.030 Development Standards” document and put everything what’s related to development conventions into it. This document gets approval and will be shared among all developers. Later, additional sections have to be added, and usually the development lead is responsible for doing this. However, sometimes used development techniques are not documented properly, and therefore the development solutions deviate from each other, or from the initially agreed standards. My advice would be the following: keep the MD.030 as a base document, and add a Wiki on top. The “Development Wiki” covers the following: Collect input from every developer without updating the MD.030 directly Collect additional topics that might need further specification Allow a discussion about such topics by reviewing/updating the wiki directly Add also decisions or open questions right into it. In one of my own projects we were using this “Developer Wiki” quite extensive, and my experience is very positive. We had different sections in it, good cross references, but also additional material like code templates, links to external web pages etc. By using this wiki, the development standards became “owned” by the right group of people, the developers. They recognized that information sharing can improve the overall development quality, but will also reduce the workload on individuals. Finally, the wiki was much more accurate and helpful for the daily development work than our initial MD.030, and we all decided to retire the document completely. Summary: Information sharing in the development area is very important! The usual “MD.030 Development Standards“ is a good starting point, but should be combined with a “Development Wiki”, allowing everyone to address and discuss necessary improvements. A well-structured Wiki can replace the document in some sections completely. Side Note: The corresponding task in Oracle OUM (Oracle Unified Method) is DS.050 ‘Determine Design and Build Standards’ Volker

• Thoughts (on Windows Phone 7) from the MVP Summit

  - by Chris Williams

  Last week I packed off to Redmond, WA for my annual pilgrimage to Microsoft's MVP Summit. I'll spare you all the silly taunting about knowing stuff I can't talk about, etc... and just get to the point. I'm a XNA/DirectX MVP, an ASP Insider and a Languages (VB) Insider... so I actually had access to a pretty broad spectrum of information over the last week. Most of my time was focused on Windows Phone 7 related sessions, and while I can't dig deep into specifics, I can say that Microsoft is definitely not out of the fight for Mobile. The things I saw tell me that Microsoft is listening and paying attention to feedback, looking at what works & what doesn't and they are working their collective asses off to close the gap between Google and Apple. Anyone who has been in this industry for a while can tell you Microsoft does their best work when they are the underdog. They are currently behind, and have a lot of work ahead of them, but this is when they bring all their resources together to solve a problem. After the week I spent in Redmond, and the feedback I heard from other MVPs, and the technological previews I saw... I feel confident in betting heavily on Microsoft to pull this off.

• Threading models when talking to hardware devices

  - by Fuzz

  When writing an interface to hardware over a communication bus, communications timing can sometimes be critical to the operation of a device. As such, it is common for developers to spin up new threads to handle communications. It can also be a terrible idea to have a whole bunch of threads in your system, an in the case that you have multiple hardware devices you may have many many threads that are out of control of the main application. Certainly it can be common to have two threads per device, one for reading and one for writing. I am trying to determine the pros and cons of the two different models I can think of, and would love the help of the Programmers community. Each device instance gets handles it's own threads (or shares a thread for a communication device). A thread may exist for writing, and one for reading. Requested writes to a device from the API are buffered and worked on by the writer thread. The read thread exists in the case of blocking communications, and uses call backs to pass read data to the application. Timing of communications can be handled by the communications thread. Devices aren't given their own threads. Instead read and write requests are queued/buffered. The application then calls a "DoWork" function on the interface and allows all read and writes to take place and fire their callbacks. Timing is handled by the application, and the driver can request to be called at a given specific frequency. Pros for Item 1 include finer grain control of timing at the communication level at the expense of having control of whats going on at the higher level application level (which for a real time system, can be terrible). Pros for Item 2 include better control over the timing of the entire system for the application, at the expense of allowing each driver to handle it's own business. If anyone has experience with these scenarios, I'd love to hear some ideas on the approaches used.

• Modular Database Structures

  - by John D

  I have been examining the code base we use in work and I am worried about the size the packages have grown to. The actual code is modular, procedures have been broken down into small functional (and testable) parts. The issue I see is that we have 100 procedures in a single package - almost an entire domain model. I had thought of breaking these packages down - to create sub domains that are centered around the procedure relationships to other objects. Group a bunch of procedures that have 80% of their relationships to three tables etc. The end result would be a lot more packages, but the packages would be smaller and I feel the entire code base would be more readable - when procedures cross between two domain models it is less of a struggle to figure which package it belongs to. The problem I now have is what the actual benefit of all this would really be. I looked at the general advantages of modularity: 1. Re-usability 2. Asynchronous Development 3. Maintainability Yet when I consider our latest development, the procedures within the packages are already reusable. At this advanced stage we rarely require asynchronous development - and when it is required we simply ladder the stories across iterations. So I guess my question is if people know of reasons why you would break down classes rather than just the methods inside of classes? Right now I do believe there is an issue with these mega packages forming but the only benefit I can really pin down to break them down is readability - something that experience gained from working with them would solve.

• Force startx to run X in a specific resolution and refresh Rate

  - by Z9iT

  From my past experience (using Win-Xp), this particular monitor works only on 60Hz , Best resolution being 1024x768. I have "installed and configured" Ubuntu 12.04 Minimal (on USB stick) so that most of the time terminal is used, however, whenever there is a need to enter GUI, I may issue startx command to go into gnome. However the problem is that on this particular system, issuing this command poses problem because its default refresh rate won't synchronize with the monitor. The display keep on flickering and utterly unreadable. It is visible that gnome has been loaded and default wallpaper and desktop items are visible. But the problem is due to refresh rate different than 60Hz. I am looking for a command attribute to startx command which will force the refresh rate to 60Hz and resolution preferably to 1204x768 I can open terminals with Ctrl+Alt+T and enter commands. Key combinations like Ctrl+Alt+NumPlus works flawlessly in distributions like solaris, but it's not working for me. Also the commands like xrandr -r 60 60 being refresh rate wont work. The same problem is faced even when I boot from a live CD

• Experienced programmer, beginner at web design, tools for effective maintainable web design? [closed]

  - by Clinton

  I do quite a bit of programming in my work, which I'm comfortable with, but recently I've being trying to do some web-design for non-work related reasons. I've got a Drupal site up and running, and added some content. But they all look fairly basic. Header with some content. It doesn't look particularly polished. Anyway, as an example, what I wanted to do was make some "bubbles", each with some text in them. From a programmers point of view, say: bubble(question_text, answer_text) might expand to a box with some border, with "Question: " + question_text then "Answer: " + answer_text. Of course I'd have lots of these bubbles, but I'd like to change their look and feel in one place, so simple HTML would be a maintainable nightmare. I also want to lay them out on the screen in some fashion. I was thinking a mixture of javascript and CSS, or possibly use PHP which Drupal uses. On the other hand, I fear I might be taking a 1990s approach to this, and that there's actually tools available now that make this process a lot easier. I'm just wondering what the best approach to this sort of task is? Should I be using offline web design software and copying the code to Drupal, and if so, any recommendations? I'm sorry if my question is a bit vague, because I'm not really sure what question I should be asking. I'd appreciate if you answer and comment, and I'll try my best to be more specific as I understand more.

• Why should I use MSBuild instead of Visual Studio Solution files?

  - by Sid

  We're using TeamCity for continuous integration and it's building our releases via the solution file (.sln). I've used Makefiles in the past for various systems but never msbuild (which I've heard is sorta like Makefiles + XML mashup). I've seen many posts on how to use msbuild directly instead of the solution files but I don't see a very clear answer on why to do it. So, why should we bother migrating from solution files to an MSBuild 'makefile'? We do have a a couple of releases that differ by a #define (featurized builds) but for the most part everything works. The bigger concern is that now we'd have to maintain two systems when adding projects/source code. UPDATE: Can folks shed light on the lifecycle and interplay of the following three components? The Visual Studio .sln file The many project level .csproj files (which I understand an "sub" msbuild scripts) The custom msbuild script Is it safe to say that the .sln and .csproj are consumed/maintained as usual from within the Visual Studio IDE GUI while the custom msbuild script is hand-written and usually consumes the already existing individual .csproj "as-is"? That's one way I can see reduce overlap/duplicate in maintenance... Would appreciate some light on this from other folks' operational experience

• Building own kernel on ubuntu

  - by chris

  Hi, I'm trying to build my own kernel, as I want to write a kernel program which I need to compile into the kernel. So what did I do? Download from kernel.org, extract, do the make menuconfig and configure everything as needed, do a make, do a make modules_install, do a make install and finally do a update-grub. Result: It doesn't boot at all.... Now I had a look here and it describes a different way of compiling a kernel. Could this be the reason whz my way did not work? Or does anyone else have an idea why my kernel doesn't work? ######## Edit Great answer, ty. Oli. But I tried it the old fashioned way, and after one hour of compiling I got this message: install -p -o root -g root -m 644 ./debian/templates.master /usr/src/linux-2.6.37.3/debian/linux-image-2.6.37.3meinsmeins/DEBIAN/templates dpkg-gencontrol -DArchitecture=i386 -isp \ -plinux-image-2.6.37.3meinsmeins -P/usr/src/linux-2.6.37.3/debian/linux-image-2.6.37.3meinsmeins/ dpkg-gencontrol: error: package linux-image-2.6.37.3meinsmeins not in control info make[2]: *** [debian/stamp/binary/linux-image-2.6.37.3meinsmeins] Error 255 make[2]: Leaving directory `/usr/src/linux-2.6.37.3' make[1]: *** [debian/stamp/binary/pre-linux-image-2.6.37.3meinsmeins] Error 2 make[1]: Leaving directory `/usr/src/linux-2.6.37.3' make: *** [kernel-image] Error 2

• Responsive Design: Which Framework Should I Use? CSS3 & HTML5

  - by Jayhal

  I've been looking for a suitable set of HTML5/CSS3 foundation files to start new projects on. I started off piecing together my own files, but I believe I might be better served in finding a solid and fairly compatible(with me) CSS3/HTML5 framework and then tweaking certain things that may not best suit my own process. I'd love to find something that is responsive and that includes aspects focusing on layout, type(hor and vert baselines), form and interface components, cross-browser issues, and preferably built on something other than a just imple css reset, but that does include rebuilding elements consistently across browsers for a clean work slate. Extra features like polyfills or others area great, as is good documentation and examples. So far, off the top of my head I know of, Skeleton 1140 Grid 320 & Up (plus BP) HTML5 Boilerplate 2.0 and Mobile Inuit.css Less Framework Fluir Perkins.Less A few WP themes Are there any great one I don't know about? I work a lot in WP, and something that is easily incorporated (but also stand alone) is ideal. Plugins and wide set feature while maintaining the ability to cut it down when needed(flexibility) is also a big plus, and in par with a faster learning, since I want to start using whatever I find immediately . What are some of the better options you guys might be able to recommend? Systems or scripts, plugins, and other related tools are also welcome, Thanks!

• Dedicated server: managed hosting or manage it myself?

  - by ddawber

  We're currently hosting a number of sites on a self-managed dedicated server. Some companies, however, offer a managed dedicated server hosting service. They offer: Roughly the same server spec Ticketing system support Managed daily backups Virtual firewall (but with a limit of 10 IP addresses allowed through at any one time) Now, this managed hosting is at extra expense - somewhere in the region of $500 per month, and the limit on the number of IP addresses they'll manage on the firewall is also a real pain. My thinking is it would be better and cheaper to Stay with the same host since the dedicated box is fine Get an Amazon AWS account and use their server to manage backups; there are a number of good tools that can be used to automate the process Configure iptables so that I have complete control of the firewall I want to know Is a managed virtual firewall likely to be more secure than me configuring iptables? Whether, in your opinion, it's best to let someone else take care of backups? If, from your experience, there's anything else i'm missing that warrants using managed hosting over a DIY service? I think there is some reluctance to not having managed hosting since a managed host in effect takes responsibility for your server, whereas any hardware or security issues with a server that we manage would mean we are forced to hold our hands up when a client site goes down. That said, I personally don't think a managed host does that much in the day to day running of your server (backups are automatic, OS updates are carried out with ease, etc.).

• What should I recommend a small company looking for C# developers

  - by Coder

  Here is the issue. I am a senior developer, and one of the start-ups I designed the system (management system/database/web) a long time ago, have grown and need software updates. I have left their system to another developer long time ago, but apparently he has left the job, and so they are asking me if I can suggest them where to find a new one. The problem is that the company has no clue that the IT is not cheap. They expect multiple features to be added for 40$, so that's an issue. Actually one of the reasons why I left the project when I did. Lots of expectations, little pay, also I know those people outside work, so I decided to avoided stressing the nonwork-relationships and left the project gracefully. Today they asked me for an advice, and I told them that the feature list they want is probably going to cost some if they'll get a senior developer for the job. So I guess their best bet is to find someone who loves coding and has just finished the school. Which would give someone a chance to code for money which is good for a student, and at the same time, allow the student to get some hands on experience. Then again, the system is not exactly 20 line console program, there is an MSSQL database, ASP.NET web page and content management system with all the AJAX stuff and some other things. So student straight out of school could have some problems with that. But, I thought about the issue some more, and I think that junior developer is a tricky deal, without mentoring, he can either screw up royally, or just do what's asked. Also, it seems no one is coming to interviews at all, which is weird, or maybe not. What should I suggest them?

• Advice on choosing a book to read

  - by Kioshiki

  I would like to ask for some recommendations on useful books to read. Initially I had intended on posting quite a long description of my current issue and asking for advice. But I realised that I didn’t have a clear idea of what I wanted to ask. One thing that is clear to me is that my knowledge in various areas needs improving and reading is one method of doing that. Though choosing the right book to read seems like a task in itself when there are so many books out there. I am a programmer but I also deal with analysis, design & testing. So I am not sure what type of book to read. One option might be to work through two books at the same time. I had thought maybe one about design or practices and another of a more technical focus. Recently I came across one book that I thought might be useful to read: http://xunitpatterns.com/index.html It seems like an interesting book, but the comments I read on amazon.co.uk show that the book is probably longer than it needs to be. Has anyone read it and can comment on this? Another book that I already own and would probably be a good one to finish reading is this: http://www.amazon.co.uk/Code-Complete-Practical-Handbook-Construction/dp/0735619670/ref=sr_1_1?ie=UTF8&qid=1309438553&sr=8-1 Has anyone else read this who can comment on its usefulness? Beyond these two I currently have no clear idea of what to read. I have thought about reading a book related to OO design or the GOF design patterns. But I wonder if I am worrying too much about the process and practices and not focusing on the actual work. I would be very grateful for any suggestions or comments. Many Thanks, Kioshiki

• Engine for 2D Top-Down Physics-Based Skeletal Animation

  - by RylandAlmanza

  I just watched at the Sui Generis video, and was completely amazed. Specifically, the part where the big troll thing is beating up the player with his flail. This got me really excited, and I would like to try implementing something like this in a 2D Top-Down format. Something like this. That atloria example seems simple enough, but it's not exactly what I'm looking to make. I think atloria is using predefined animations, where as I would like to make something more physics-based like the Sui Generis engine does. So, I'm wondering what physics engines might work for something like this, and if I'd need to implement my own skeletal system, or if I could just use "joints" and such from the engine. The only experience I have in terms of physics engines is Box2D, which I've heard shouldn't be used for top-down settings, and I can think of a few reasons it wouldn't work out well. One of those reasons being gravity. In box 2D, gravity pulls towards a side of the screen (usually the bottom.) I wouldn't want my player's forearms constantly being pulled to one side. :) Also should mention that the programming language doesn't matter all that much to me. I'm currently playing with HTML5 stuff, though. :) Thanks in advance!

• How to make a good portfolio for IT student (who loves programming) like me?

  - by Viet

  I am currently a college student, and going to apply for an university in probably next month. Unlike art student who easily put on their works such as models, designs and so on on their portfolio; I am hitting a dead corner trying to find a "creative" way to showcase my work as a programmer. It would be normal if programmer shows his good project with source code and everything else. Well, it should be no problem with actual "good" projects, but all of my projects are crappy (can't help it because I am still student, and don't have much work experience) and I don't even know it's worth to show. Nonetheless, I have learned a lot in only 1 year since I started programming. I am now familiar with Java, PHP, Actionscript3, C#, Objective-C and on my way to learn Ruby. I plan to build a Flash portfolio using Actionscript with Ruby as backend to show what I have learnt. The problem is idea. How to show people that I learned a lot of useful thing? Otherwise I hit the dead end and LOL just show what I have on Github (but i certainly never want that...)

• Student Life in Nigeria

  - by FelixWehmeyer

  They say that the Nigerian way of life involves being able and ready to succeed in life no matter the obstacles. My name is Olawale Obasola, graduated from Covenant University ’07 and presently working as a graduate consultant in Oracle. I will give you an insight into the student life in Nigeria. Nowadays, being a graduate in Nigeria is not the easiest thing; the life after graduation is much harder than one would normally imagine. I guess it isn’t helped with the Economical uproar of the last few years but it’s as grueling as it can get.  Also the Upper vs Lower class phenomena makes the journey a little too much hurried as it is easier to lose one’s way. Joining Oracle is a dream come-true as it further enhances my stance of taking Technology to the core of Nigeria. My initial perception about joining Oracle is that am going to be monitored every single second and my life would practically revolve around work but ever since I stepped in here, it has been an amazing experience. As much as the work can be stressful at times, it’s also the best place I have ever worked in and the atmosphere is great. My team is the best Pre-Sales team in the region and I gain invaluable knowledge every minute, we have a bond and understanding that helps propel each other to achieve more. The Life of a Nigerian graduate isn’t a bed of roses but I have a strong will and personality to emerge from any hardship to succeed. We show the true strength and spirit of Africa, we never give up and would never settle for anything less than the best.

• Ubuntu 12.04 Freezes w/ Ethernet Unplugged + Wireless Drops (Acer Aspire 5516)

  - by Grand Master T

  Ubuntu 12.04-12.10 32/64 freezes or won't boot if the Ethernet cable is unplugged and will not hold a wireless connection. Here is my scenario... Laptop: Acer Aspire 5516 Wireless card: Broadcom BCM4312 Ubuntu 12.04 32/64 Issues Unity 3d won't load without the Ethernet cable plugged in. If I let it load with Ethernet plugged in, it will freeze once I disconnect the cable. Unity 2d will load without the Ethernet cable plugged. In Unity 2d, wireless cannot hold a connection. I can connect to a Wireless network, but when I try to use it (i.e. open a browser), it disconnects. I can reconnect by disabling wireless (uncheck Enable Wireless), re-enable wireless, and reconnect. But, it will disconnect again once I start using it. Ubuntu 12.10 Issues Since 12.10 only gives me the option to load 3d (I assume), I experience the same thing as the first issue in 12.04. Attempted Solutions Enable networking/LAN in BIOS Set LAN first in boot priority in BIOS Remove STA wireless driver (bcmwl-kernel-source) and install b43 low power driver (firmware-b43-lpphy-installer). Remove default Network Manager and install Wicd. So far, I have had no luck with fixing this issue. Does anyone have any further suggestions?

• How to Reap Anticipated ROI in Large-Scale Capital Projects

  - by Sylvie MacKenzie, PMP

  Only a small fraction of companies in asset-intensive industries reliably achieve expected ROI for major capital projects 90 percent of the time, according to a new industry study. In addition, 12 percent of companies see expected ROIs in less than half of their capital projects. The problem: no matter how sophisticated and far-reaching the planning processes are, many organizations struggle to manage risks or reap the expected value from major capital investments. The data is part of the larger survey of companies in oil and gas, mining and metals, chemicals, and utilities industries. The results appear in Prepare for the Unexpected: Investment Planning in Asset-Intensive Industries, a comprehensive new report sponsored by Oracle and developed by the Economist Intelligence Unit. Analysts say the shortcomings in large-scale, long-duration capital-investments projects often stem from immature capital-planning processes. The poor decisions that result can lead to significant financial losses and disappointing project benefits, which are particularly harmful to organizations during economic downturns. The report highlights three other important findings. Teaming the right data and people doesn’t guarantee that ROI goals will be achieved. Despite involving cross-functional teams and looking at all the pertinent data, executives are still failing to identify risks and deliver bottom-line results on capital projects. Effective processes are the missing link. Project-planning processes are weakest when it comes to risk management and predicting costs and ROI. Organizations participating in the study said they fail to achieve expected ROI because they regularly experience unexpected events that derail schedules and inflate budgets. But executives believe that using more-robust risk management and project planning strategies will help avoid delays, improve ROI, and more accurately predict the long-term cost of initiatives. Planning for unexpected events is a key to success. External factors, such as changing market conditions and evolving government policies are difficult to forecast precisely, so organizations need to build flexibility into project plans to make it easier to adapt to the changes. The report outlines a series of steps executives can take to address these shortcomings and improve their capital-planning processes.

• What are some good resources for creating a game engine in XNA?

  - by Glasser

  I'm currently a student game programmer working on an indie project. We have a team of eleven people (five programmers, four artists, and two audio designers) aboard, all working hard to help design this game. We've been meeting for months now and so far we have a pretty buffed out Game Design Document as well as much audio/visual concept art. Our programmers are itching to progress on our own end. Each person in our programming team is well versed in C++, but is very familiar with C#. We have enough experience and skill that we're confident that we will be successful with our game, and we're looking to build our own game engine in XNA as it seems like it would be worth our time and effort in the end. The game itself will be a 2D beat 'em up style game to be released over xbox live and the PC. It's play style will be similar to that of Castle Crashers or Scott Pilgrim vs The World. We want to design the game engine to allow us to better implement our assets into the game as well as to simplify the creation of design elements/mechanics. Currently between our programmers, we have books such as "XNA 4.0" and "Game Coding Complete, Third Edition," but we'd still like more information on both XNA and (especially) building a game engine from scratch. What are any other good books, websites, or resources we could use to further map out and program our game engine?

• Transitioning from Internal to Public Speaking

  - by TJB

  For whatever reason, I've always enjoyed giving presentations. As a developer, I've grown from giving the rare presentation when asked to frequently doing 'brown bag' talks and other presentations on new technology, projects etc. I'd like to expand as a presenter and start giving talks in public, outside of just my workplace, and I'm looking for tips on how to get there. At a high level, I'd love to know a good path to take & useful tips to help me grow from just giving internal talks to my group (10-20 people) to eventually be a presenter at medium-large sized conferences. Here are some specific questions, but I will take any advice you can offer: 1. How much experience do I need to speak at user groups etc? I've been in industry for around 5 years, which pales in comparison to most speakers that I normally see. 2. What is a good venue for my 1st public talk? 3. What surprises can I expect when transistioning from speaking to a small group of friends to presenting in public to strangers? I live in southern California and my background is mostly .net / web, so if you have any specific user group / venues those are also greatly appreciated.

• Etiquette when asking questions in an IRC channel

  - by Zarkonnen

  Many larger OSS projects maintain IRC channels to discuss their usage or development. When I get stuck on using a project, having tried and failed to find information on the web, one of the ways I try to figure out what to do is to go into the IRC channel and ask. But my questions are invariably completely ignored by the people in the channel. If there was silence when I entered, there will still be silence. If there is an ongoing conversation, it carries on unperturbed. I leave the channel open for a few hours, hoping that maybe someone will eventually engage me, but nothing happens. So I worry that I'm being rude in some way I don't understand, or breaking some unspoken rule and being ignored for it. I try to make my questions polite, to the point, and grammatical, and try to indicate that I've tried the obvious solutions and why they didn't work. I understand that I'm obviously a complete stranger to the people on the channel, but I'm not sure how to fix this. Should I just lurk in the channel, saying nothing, for a week? That seems absurd too. A typical message I send might be "Hello all - I've been trying to get Foo to work, but I keep on getting a BarException. I tried resetting the Quux, but this doesn't seem to do anything. Does anyone have a suggestion on what I could try?"

• Laptop Display Not Working

  - by etrask

  Hello, I just purchased this laptop. It is working fine but I want to use Xubuntu on it. I managed to get 10.04 installed and running but it did not recognize/use the wireless card. So I want to try 10.10. However, every time I try, the screen goes black and never comes back on. I have tried the Live CD and Alternate install CDs, for both Ubuntu and Xubuntu 10.10. After I select "Install Ubuntu" or "Try Ubuntu", the screen blacks out and never displays anything. So I deleted "quiet" and "splash" off the command line to see what messages would come up. A bunch of text flies by but it ends at: [time] TCP established hash table entries: 524288 (order: 11, 8388608 bytes) [time] TCP bind hash table entries 65536 (order: 8, 1048576 bytes) [time] TCP: Hash tables configured (established 524288 bind 65536) [time] TCP reno registered [time] UDP hash table entries: 2048 (order: 4, 65536 bytes) [time] UDP-Lite hash table entries: 2048 (order: 4, 65536 bytes) [time] NET: Registered protocol family 1 And freezes here forever. I have tried nomodeset, vga=771, and xforcevesa with no progress. Is my video card simply not going to work with this distro? It seems strange that 10.04 would work fine but not 10.10. Any help is appreciated, thank you.
