• Why does my root filesystem keep becoming read-only?

  - by Scott Severance

  I've lately been having an issue with my root filesystem becoming readonly. It happens some amount of time after boot. I don't know exactly when it happens, as I don't usually notice it until something such as suspending the computer or printing fails. It seems to be fairly random. Since most of my system is on that partition, I can't re-mount it without rebooting. After this happens, the system runs a fsck. Sometimes it prompts to fix problems; other times it apparently finds none. To troubleshoot, I've searched through the logs but found nothing relevant. This might be due in part to not knowing when the actual errors took place. The filesystem is apparently good to begin with, as when fsck runs its fixes it doesn't report any errors. I've scanned the disk with SpinRite. A while ago, SpinRite found and recovered from some bad sectors on the hard drive. I ran a level 4 scan (a thorough scan) after this probem appeared, but SpinRite found nothing. The SMART data reports that the disk is OK with 63 bad sectors. The number of bad sectors hasn't changed recently. I realize that the disk isn't in the best of conditions, and I have complete backups in case of catastrophic failure. Yet the lack of errors in the logs, combined with SpinRite's test results and the unchanged SMART data makes me think that this problem has some cause other than disk failure. Other than disk failure, what could cause my symptoms?

• Pandaboard crash on startup or freeze after minutes

  - by Meach

  I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons. Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands: sudo add-apt-repository ppa:tiomap-dev/release sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ubuntu-omap4-extras At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays: ldconfig deferred processing now taking place Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running: sudo apt-get install --reinstall pvr-omap4-dkms I reboot. Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes. I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091 So I typed this in: update-rc.d ondemand disable apt-get -y install cpufrequtils echo 'ENABLE="true" GOVERNOR="performance" MAX_SPEED="0" MIN_SPEED="0"' > /etc/default/cpufrequtils cpufreq-set -r -g performance reboot But it doesn't seems to fix the bug. Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this: [0.297271] CPU1: Unknown IPI message 0x1 [0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16 [0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts [0.354766] omap_hwmod_mux_init: Could not allocate device mux entry [2.107086] thermal_get_slope:Getting slope is not supported for domain gpu [2.107116] thermal_get_offset:Getting offset is not supported for domain gpu [2.107299] stm_fw: vendor driver stm_ti1.0 registered [8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0 Any idea what can be wrong? I am not that good with Ubuntu so any help will be appreciated. Cheers! Meach

• An experiment: unlimited free trial

  - by Alex.Davies

  The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

• for an ajax heavy web application which would be better SOAP or REST?

  - by coder

  I'm building an ajax heavy application (client-side strictly html/css/js) which will be getting all the data and using server business logic via webservices. I know REST seems to be the hot topic but I can't find any good arguments. The main argument seems to be its "light-weight". My impression so far is that wsdl/soap based services are more expressive and allow for more a more complex transfer of data. It appears that soap would be more useful in the application I'm building where the only code consuming the services will be the js downloaded in the client browser. REST on the other hand seems to have a smaller entry barrier and so can be more useful for services like twitter in allowing other developers to consume these services easily. Also, REST seems to Te better suited for simple data transfers. So in summary SOAP is useful for complex data transfer and REST is useful in simple data transfer. I'm currently under the impression that using SOAP would be best due to the complexity of the messages but perhaps there's other factors. What are your thoughts on the pros/cons of soap/rest for a heavy ajax web app?

• Buffer System For Items

  - by Ohmages

  I am going to reference this image of what I want to accomplish in JavaScript. This is the Diablo buffer system. This question may be a bit advanced (or possibly not even allowed). But I was wondering how you might go about implementing this type of system in a JavaScript game. Currently to implement such a system in JavaScript escapes me, and I am turning to SO to get some suggestions, ideas, and hopefully some insight in how I could accomplish this without being to costly on the CPU. Some thoughts of mine for implementing such a system would be to: Create DIVS within a DIV that hold each position of the inventory Go through each item you own in a container and see which DIV it belongs to Make said item images the DIVs image This type of system might possibly work if ALL items were 1x1, but for this example its not going to work out. I am at a complete lost of ideas how to even accomplish this. Although, maybe rendering directly to the canvas and checking mouse cords could work, there would more than likely be A HUGE annoyance when checking if other items are overlapping each other (meaning you cant place the item down, and possibly switching item with the cursor item ). That said, what am I left with? Do I need to makeshift my own hack system with messy code, or is there some source out there (that I don't know about) that has replicated this type of system in their own game. I would be very grateful to get some replies on how you might go about doing this, and will accept answers that can logically explain how you might implement such a system (code is not required). P.S. Id like to use pure JavaScript, and nothing else (even though it might be "reinventing the wheel", I also like to learn).

• correct way to implement auth/acl in mvc

  - by WiseStrawberry

  I am looking into making a correctly laid out MVC auth/acl system. I think I want the authentication of a user (and the session handling) to be seperate from the ACL system. (I don't know why but this seems a good idea from the things I've read) What does mvc have to do with this question you ask? Because I wish for the application to be well integrated with my acl. An example of a controller (CodeIgniter) <?php class forums extends MX_Controller { $allowed = array('users', 'admin'); $need_login = true; function __construct() { //example of checking if logged in. if($this->auth->logged_in() && $this->auth->is_admin()) { echo "you're logged in!"; } } public function add_topic() { if($this->auth->allowed('add_topic') { //some add topic things. } else { echo 'not allowed to add topic'; } } } ?> My thoughts $this->auth would be autoloaded in the system. I would like to check the $allowed array against the user currently (not) logged in and react accordingly. Is this a good way of doing things? I haven't seen much literature on mvc integration and auth. I want to make things as easy as possible.

• Functions that only call other functions. Is this a good practice?

  - by Eric C.

  I'm currently working on a set of reports that have many different sections (all requiring different formatting), and I'm trying to figure out the best way to structure my code. Similar reports we've done in the past end up having very large (200+ line) functions that do all of the data manipulation and formatting for the report, such that the workflow looks something like this: DataTable reportTable = new DataTable(); void RunReport() { reportTable = DataClass.getReportData(); largeReportProcessingFunction(); outputReportToUser(); } I would like to be able to break these large functions up into smaller chunks, but I'm afraid that I'll just end up having dozens of non-reusable functions, and a similar "do everything here" function whose only job is to call all these smaller functions, like so: void largeReportProcessingFunction() { processSection1HeaderData(); calculateSection1HeaderAverages(); formatSection1HeaderDisplay(); processSection1SummaryTableData(); calculateSection1SummaryTableTotalRow(); formatSection1SummaryTableDisplay(); processSection1FooterData(); getSection1FooterSummaryTotals(); formatSection1FooterDisplay(); processSection2HeaderData(); calculateSection1HeaderAverages(); formatSection1HeaderDisplay(); calculateSection1HeaderAverages(); ... } Or, if we go one step further: void largeReportProcessingFunction() { callAllSection1Functions(); callAllSection2Functions(); callAllSection3Functions(); ... } Is this really a better solution? From an organizational point of view I suppose it is (i.e. everything is much more organized than it might otherwise be), but as far as code readability I'm not sure (potentially large chains of functions that only call other functions). Thoughts?

• unreachable subnet in one direction

  - by Carl Michaud

  I'm unable to route traffic to a subnet in my home. Here's my topology: INET <- Router A <- Router B <- WIFI AP where: Router A - ARRIS TG862G/CT (from comcast) - WAN DHCP, LAN 10.0.0.99 Router B - Linksys WRT400N with DD-WRT - WAN 10.0.0.12 , LAN 10.0.1.1 I was able to use DD-WRT to configure a static route for the 10.0.1.x network back to the 10.0.0.x network. But I'm not sure if i can do the reverse on the ARRIS router and was looking for suggestions on how to fix that. I've set things up this wasy because I am using OpenDNS to mange internet content for my kids and of course I wasn't able to configure DNS to my liking on Router A either. So at present I'm using Router A on 10.0.0.x to provide a private unfiltered WIFI AP (no ssid broadcast) that I use for netflix only and then I use router B to provide a filtered WIFI AP for the rest of my WIFI devices on 10.0.1.x. However I would like to be able to connect to my 10.0.1.x devices from the internet via dynamic dns; but I can't see anything behind router B this way. Thoughts?

• License validation and calling home

  - by VitalyB

  I am developing an application that, when bought, can be activated using a license. Currently I am doing offline validation which is a bit troubling to me. I am aware there is nothing to do against cracks (i.e modified binaries), however, I am thinking to trying to discourage license-key pirating. Here is my current plan: When the user activates the software and after offline validation is successful, it tries to call home and validate the license. If home approves of the license or if home is unreachable, or if the user is offline, the license gets approved. If home is reached and tells the license is invalid, validation fails. Licensed application calls home the same way every time during startup (in background). If license is revoked (i.e pirated license or generated via keygen), the license get deactivated. This should help with piracy of licenses - An invalid license will be disabled and a valid license that was pirated can be revoked (and its legal owner supplied with new license). Pirate-users will be forced to use cracked version which are usually version specific and harder to reach. While it generally sounds good to me, I have some concerns: Users tend to not like home-calling and online validation. Would that kind of validation bother you? Even though in case of offline/failure the application stays licensed? It is clear that the whole scheme can be thwarted by going offline/firewall/etc. I think that the bother to do one of these is great enough to discourage casual license sharing, but I am not sure. As it goes in general with licensing and DRM variations, I am not sure the time I spend on that kind of protection isn't better spent by improving my product. I'd appreciate your input and thoughts. Thanks!

• 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.

• No space left on disk

  - by Ned

  folks. I'm trying to copy/move files to an external 1 TB hard drive with about 50 GB remaining space. I receive a "no space left on disk" when I try. I've moved files off and retried, but still get the same message. Disk Usage Analyzer, Properties, and freeware Treesize all report available hard drive space of about 50 GB. I've tried df -i (50 GB available) and df -k, with the latter reporting only 1% of inode usage. I've been able to save files from Firefox to the drive also. I can't even rename files without getting the message. Yesterday in the midst of trying to figure this out I tried to move 4 files to the drive and got the message. Today, I found them on the drive. What's up with that? (That's the only time that has happened to my knowledge.) Is this an ubuntu problem? or is my hard drive just about to fail because of something like a controller problem? Any thoughts would be appreciated.

• Ubuntu 12.04 Network Manager: unable to save manual setting to set up a static ip

  - by Andy

  I am fairly familiar with setting up servers, and ubuntu is generally my flavor of choice, but I just installed 12.04 desktop and I am seeing some behavior in network manager that is really puzzling. The network connection works fine if I leave it set on dhcp, but I would like a static IP address for my new web server. When I go into network manager and edit the connection for the one and only NIC I can select MANUAL from the dropdown menu but as soon as I do the Save button becomes greyed out. Even after filling out all fields for the connection it is still grey and I am unable to save the static IP connection information. Any thoughts would be greatly appreciated. I'm hoping there is just some new setting that I am unaware of.... On another note, if I stop the network manager and go edit the interfaces file (and the appropriate hosts/routes/dns files), I do get a static ip address assigned and I can contact my server from the outside, however, the server cannot find the internet. Can't ping even its own ip... I can ping the loopback interface though. I'm really confused on this one. Hoping someone can offer some help.

• What is the best way to exploit multicores when making multithread games?

  - by Keeper

  Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses at the university (still a student). The big question is simple, but a bit abstract: What thread related steps in game design do I need to take, before implementation? Now trying to be more specific. Let's say, as an example, that I'm making a small board game (like Monopoly) that I want to be multithreaded. My goal Is that this multithreaded game will exploit the best of the multicore system, lets say 4-6 cores (like in i7 processors). My answer to this question at the moment is, one thread for each of these four basic components: GUI User Input / Output AI (computer rival) Other game related calculations (like shortest path from A to B, or level up status change) I'm not an expert (yet!), and I'm sure there are better answers out there. Any suggestion, answer, different approach will be helpful. Some thoughts: Maybe splitting the main database is a good way.. (or total disaster.. )

• Intermittent freezing on a Macbook Pro 7,1

  - by LR0

  I recently installed Ubuntu 12.10 on my MacBook Pro 7, 1. I used to have 11.10 on it. I've encountered a problem were I can boot up and the login screen works flawlessly. When I attempt to log into my account I set up during install it would only show the default wallpaper and the mouse was frozen. In other words it was logging on but froze up. Is what it seems like. When I rebooted I attempted to log into the guest account. I was able to log in and it seemed everything worked so I tried to update everything figuring it may be the problem. After updating and restarting as prompted I tried to login to my account. It still froze up but this time showing "glitched up" (you can see the dock and status bar but they don't look like they should) and still freezes. This is all happening on the guest account to. I was unable to find a similar article on the Internet therefore I am asking; Any thoughts Ubuntu?

• Designing business objects, and gui actions

  - by fozz

  Developing a product ordering system using Java SE 6. The previous implementations used combo boxes, text fields, and check boxes. Preforming validation on action events from the GUI. The validation includes limiting existing combo boxes items, or even availability. The issue in the old system was that the action was received and all rules were applied to the entire business object. This resulted in a huge event change as options were changed multiple times. To be honest I have no idea how an infinite loop wasn't produced. Through the next iteration I stepped in and attempted to limit the chaos by controlling the order in which the selections could be made. Making configuration of BO's a top down approach. I implemented custom box models, action events, beans/binding, and an MVC pattern. However I still am unable to fully isolate action even chains. I'm thinking that I've approached the whole concept backwards in an attempt to stay closest to what was already in place. So the question becomes what do I design instead? I'm currently considering an implementation of Interfaces, Beans, Property Change Listeners to manage the back and forth. Other thoughts were validation exceptions, dynamic proxies.... I'm sure there are a ton of different ways. To say that one way is right is crazy, and I'm sure it will take a blending of multiple patterns. My knowledge of swing/awt validation is limited, previously I did backend logic only. Other considerations are were some sort of binding(jgoodies or otherwise) to directly bind GUI state to BO's.

• What language and topics should be covered when teaching non-CS college students how to program?

  - by michaelcarrano

  I have been asked by many of my non-computer science friends to teach them how to program. I have agreed to hold a seminar for them that will last for approximately 1 to 2 hours. My thoughts are to use Python as the language to teach them basic programming skills. I figured Python is relatively easier to learn from what I have researched. It is also a language I want to learn which will make holding this seminar all the more enjoyable. The topics I plan to cover are as followed: Variables / Arrays Logic - If else statements, switch case, nested statements Loops - for, while, do-while and nested loops Functions - pass by value, pass by reference (is this the correct terms for Python? I am mostly a C/C++ person) Object Oriented Programming Of course, I plan to have code examples for all topics and I will try to have each example flow into each other so that at the end of the seminar everyone will have a complete working program. I suppose my question is, if you were given 1 to 2 hours to teach a group of college students how to program, what language would you choose and what topics would you cover? Update: Thank you for the great feedback. I should have mentioned in my earlier post above that a majority of the students attending the seminar have some form of programming experience whether it was with Java or using Matlab. Most of these students are 3rd/4th year Engineering students who want to get a refresher on programming before they graduate.

• What's wrong with cplusplus.com?

  - by Kerrek SB

  This is perhaps not a perfectly suitable forum for this question, but let me give it a shot, at the risk of being moved away. There are several references for the C++ standard library, including the invaluable ISO standard, MSDN, IBM, cppreference, and cplusplus. Personally, when writing C++ I need a reference that has quick random access, short load times and usage examples, and I've been finding cplusplus.com pretty useful. However, I've been hearing negative opinions about that website frequently here on SO, so I would like to get specific: What are the errors, misconceptions or bad pieces of advice given by cplusplus.com? What are the risks of using it to make coding decisions? Let me add this point: I want to be able to answer questions here on SO with accurate quotes of the standard, and thus I would like to post immediately-usable links, and cplusplus.com would have been my choice site were it not for this issue. Update: There have been many great responses, and I have seriously changed my view on cplusplus.com. I'd like to list a few choice results here; feel free to suggest more (and keep posting answers). As of June 29, 2011: Incorrect description of some algorithms (e.g. remove). Information about the behaviour of functions is sometimes incorrect (atoi), fails to mention special cases (strncpy), or omits vital information (iterator invalidation). Examples contain deprecated code (#include style). Inexact terminology is doing a disservice to learners and the general community ("STL", "compiler" vs "toolchain"). Incorrect and misleading description of the typeid keyword.

• So now Google has said no to old browsers when can the rest of us follow suit?

  - by Richard

  Google recently announced that they will no longer support older browsers on Aug 1st: http://www.bbc.co.uk/news/technology-13639875 http://gmailblog.blogspot.com/2011/06/our-plans-to-support-modern-browsers.html For this reason, soon Google Apps will only support modern browsers. Beginning August 1st, we’ll support the current and prior major release of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting the update and stop supporting the third-oldest version. There is nothing worse than looking at the patching of code that takes place to support older browsers. If we could all move towards a standards only web (I'm looking at you IE9) then surely we could spend more time programming good web apps and less trying to make them run equally on terrible non standards compliant older browsers. So when can the rest of us expect to be able to tell our clients that we no longer support older browsers? Because it seems that large corporates will continue to run older browsers and even if google chrome frame can be installed without admin privileges (it's coming soon, currently in beta) we can't expect all users to be motivated to do this. I appreciate any thoughts.

• Is learning C# as a first language a mistake?

  - by JuniorDeveloper1208

  I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

• O'reilly certification in PHP worth it?

  - by editzombie

  I asked this question over on stack overflow but I didn't realise it wasn't really the place for not so technical questions. I've seen quite a few related threads on this forum so I thought I'd try and get some feedback here: This is my first time asking a question on this forum, though I´ve read it a lot. I apologise if this is repeating a thread. I´m interested in getting into web development. I am a video editor by trade but living in Spain the way things are at the moment its very difficult to find work. I have some very basic knowledge of HTML and CSS and a little bit of flash and have designed a few little personal websites myself. I also worked for a online marketing production company where I worked a little on blog design in Blogger amongst other social media. So thats my background, but I´m trying to expand my skills and get into web development as a career or in general part of my skill base, I was thinking particularly about PHP/MySQL. I have worked a little on some of the Lynda.com tutorials and have invested in a book (Sams Teach Yourself PHP, MySQL and Apache). I´m still finding it very difficult to progress. I know I should really try some practice projects (any reccomendations would be welcome). But I was also thinking about doing one of the O´Reilly certification courses and was wondering whether it would be worthwhile for a noob like me. I hear that the courses are associated with an American University which I guess gives it more clout. Any other thoughts you guys have about how to make progress in learning web development would be fantasic. Thanks in advance.

• Multi Threading - How to split the tasks

  - by Motig

  if I have a game engine with the basic 'game engine' components, what is the best way to 'split' the tasks with a multi-threaded approach? Assuming I have the standard components of: Rendering Physics Scripts Networking And a quad-core, I see two ways of multi-threading: Option A ('Vertical'): Using this approach I can allow one core for each component of the engine; e.g. one core for the Rendering task, one for the Physics, etc. Advantages: I do not need to worry about thread-safety within each component I can take advantage of special optimizations provided for single-threaded access (e.g. DirectX offers a flag that can be set to tell it that you will only use single-threading) Option B ('Horizontal'): Using this approach, each task may be split up into 1 <= n <= numCores threads, and executed simultaneously, one after the other. Advantages: Allows for work-sharing, i.e. each thread can take over work still remaining as the others are still processing I can take advantage of libraries that are designed for multi-threading (i.e. ... DirectX) I think, in retrospect, I would pick Option B, but I wanted to hear you guys' thoughts on the matter.

• Good design for class with similar constructors

  - by RustyTheBoyRobot

  I was reading this question and thought that good points were made, but most of the solutions involved renaming one of the methods. I am refactoring some poorly written code and I've run into this situation: public class Entity { public Entity(String uniqueIdentifier, boolean isSerialNumber) { if (isSerialNumber) { this.serialNumber = uniqueIdentifier; //Lookup other data } else { this.primaryKey = uniqueIdentifier; // Lookup other data with different query } } } The obvious design flaw is that someone needed two different ways to create the object, but couldn't overload the constructor since both identifiers were of the same type (String). Thus they added a flag to differentiate. So, my question is this: when this situation arises, what are good designs for differentiating between these two ways of instantiating an object? My First Thoughts You could create two different static methods to create your object. The method names could be different. This is weak because static methods don't get inherited. You could create different objects to force the types to be different (i.e., make a PrimaryKey class and a SerialNumber class). I like this because it seems to be a better design, but it also is a pain to refactor if serialNumber is a String everywhere else.

• Windows Azure AppFabric SDK - June CTP - Download issues

  - by Charles Young

  Microsoft has announced availability of the June CTP for Windows Azure AppFabric. See http://blogs.msdn.com/b/appfabric/archive/2011/06/20/announcing-the-windows-azure-appfabric-june-ctp.aspx. This is an exciting release and provides greater insight into where the AppFabric team is heading in terms of developer and management tooling. Microsoft is offering space in the cloud to experiment with the CTP, but this is limited, so register early to get a namespace! You can download the SDK for the June CTP. However, we ran into a lot of trouble trying to do this today. Whenever we followed the link, we ended up on the page for the May CTP. We found what appeared to be a workaround which we were able to repeat on another box (and which I reported on Connect), but then a few minutes later I couldn't repeat it. Just now, the given link appears to be working every time in IE, but not in Firefox!   Frankly, the behaviour seems random!   It looks like the same URL points to two different pages, and I suspect that which page you end up on is hit and miss. The link to the download page is http://www.microsoft.com/download/en/details.aspx?id=17691. If you end up on the wrong page, try again later and you may get to the right place. Or try googling "Windows Azure AppFabric SDK CTP – June Update" and following a link to this page. For some reason, that sometimes seems to work. Good luck!

• How to stay creative when going through tough emotional times (divorce, family death, etc)? [closed]

  - by gaearon

  Hi everyone. I believe this is not a duplicate of motivation question because I want to especially emphasize the emotional breakdown. You may conquer lack of motivation by working harder and getting through the dip, however this was not the case when I was separating with my girlfriend. I actually liked the project, it was (and it still is!) my first programming job at an amazing workplace and I wasn't being pressured in any way but I found myself absolutely unable to code, blankly staring at the screen, my thoughts disorganized, the feeling of emptiness all in my chest. I could perform some straightforward coding but anything that involves creative thinking, designing abstractions, solving new problems and, worst of all, fixing bugs in legacy code, completely wiped out my brain to the point I started avoiding work, which I never have done before. Coffee only used to make it worse. Eventually I got over that, and I remember the happy day I solved a problem elegantly and thought—hell, first time in a month! Thankfully the project wasn't top priority and I had the time to catch up. I wonder now, was there any other way to boost my productivity back then? I bet people would say I should've taken a break—and I think I really should have—but what if I needed the money? Didn't want to lose my job? Are there any ways to trick your brain into being creative despite emotional losses? From your experience, would it be worth talking to my boss, collegues?

• Algorithm for procedural city generation?

  - by Zove Games

  I am planning on making a (simple) procedural city generator using Java. I need ideas on whan algorithm to use for the layout, and the actual buildings. The city will mostly have skyscrapers, not really much complex stuff. For the layout I already have a simple algorithm implemented: Create a Map with java.awt.Point keys and Integer values. Fill it with all the points in the city's bounds with the value as -1 (unnassigned) Shuffle the map, and assign the 1st 10 of the keys IDs (from 1-10) Loop until all points have IDs: Loop though all points: Assign points next to an assigned point IDs of the point next to them, if 2 or more points border the point, then randomly choose which ID the point will get. You will end up with 10 random regions. Make roads bordering these regions. Fill the inside of each region with a randomly spaced and randomly rotated grid PROBLEM: This is not the fastest way to do it. What algorithm should I use for the layout. And what should I use to make each building's design? I don't even know how I'm going to do that yet (fractals maybe). I just need some ideas, not actual code.
