• Gwibber only launches sometimes

  - by Stephen Judge

  I face this problem where Gwibber only launches sporadically. Sometimes when I click it to launch, it launches and then other times it doesn't. I can't seem to figure out what is preventing it from launching and what sort of information I need to collect, also where to collect it from to make a bug report. I have killed the gwibber-service processes in the System Monitor "it loads three processes called gwibber-service, is this normal" several times and tried to launch Gwibber again, but this doesn't seem to work. The process just called gwibber starts, then the three gwibber-service processes start, then the gwibbber process ends and the three gwibber-service processes remain but the application is still not launching. Generally, I want to know are other people facing the same problem. If someone can give me some guidance on how to triage this problem and get the information need to make a bug report I would be grateful. The upside to this though is at least when it is not launching it is preventing me from wasting endless hours reading my streams on Identi.ca and Twitter, so it is a bit Workrave for microblogging. In which case maybe I shouldn't fix this problem :-)

• Rail's FileStore with Linux Disk Caching or RAMdisk?

  - by Yo Ludke

  I have a Ruby on Rails application that stores it's catched files on the filesystem (Rails file-system cache). I was thinking about changing to memcached Store, but a short test shows it isn't a big difference in speed. From linuxatemyram.com I learned a bit about file caching. On the current machine there would be around 40..45GB RAM left which isn't needed for the application and which can be used to linux-disk-cache this rails file cache store. The disk is a RAID10 system with almost 120MB disk perfomance. How can I tell Linux to use free RAM more deliberately and not to be shy about using it? Do think it's necessary to adjust a sysyctl/.. value here, or would I have performance advantages to put the File Store root diretory on a ramdisk? (Loosing the cache during a reboot wouldn't be a problem)

• Applying Textures to Hexagonal Tiles Seamlessly

  - by PATRY

  I'm doing a tactical game (X-Com / Fallout style) for fun. I've decided to use a hexagonal map, but I'm having a graphic problem. My current map display is HUD-like, with only the border of the map cells displayed, without any texture. it's simple and allow for display of different types of informations by varying the color of the border. For exemple the "danger view mode" displays the borders with a color going from green (no damage possible) to red (prob of damage 90%). Now, It's a bit hard to differentiate the kind of tile the player is on. I could put a plain color (green is grass, pale blue is water...), but this is going to limit the possibilities. Thus, i would like to display a texture on my tiles. Since the map are generated, i can not use a picture for the whole map with the HUD over. So, my question is : does any one knows how i could generate the sealess hexagonal textures (algo or plugin), or if there is a site with some hexagonal tiles ?

• IIS7 VPS Hosting Server Configuration

  - by Craig

  I have just registered a Windows 2008 VPS hosting account which I plan on running a couple of web sites on. In the past I have just used shared hosting in which everything is set up for me, so need a few pointers. When I register a new domain it asks for a couple of name servers. How do I set this up on my server? Can I just give it the IP address of the VPS server? Do I have to register some web sites with ns1, ns2 host headers in IIS? It's all a bit confusing when never done before. I have two web sites I plan on hosting. I configured both in IIS with a different IP address (the VPS plan has 2) but when trying to access the site via IP it always displays the default web site. If I turn off the default web site it just 404's. Is there any simple tutorials for setting up a couple of sites from scratch.

• Ray Tracing concers: Efficient Data Structure and Photon Mapping

  - by Grieverheart

  I'm trying to build a simple ray tracer for specific target scenes. An example of such scene can be seen below. I'm concerned as to what accelerating data structure would be most efficient in this case since all objects are touching but on the other hand, the scene is uniform. The objects in my ray tracer are stored as a collection of triangles, thus I also have access to individual triangles. Also, when trying to find the bounding box of the scene, how should infinite planes be handled? Should one instead use the viewing frustum to calculate the bounding box? A few other questions I have are about photon mapping. I've read the original paper by Jensen and many more material. In the compact data structure for the photon they introduce, they store photon power as 4 chars, which from my understanding is 3 chars for color and 1 for flux. But I don't understand how 1 char is enough to store a flux of the order of 1/n, where n is the number of photons (I'm also a bit confused about flux vs power). The other question about photon mapping is, if it would be more efficient in my case to store photons per object (or even per Object's triangle) instead of using a balanced kd-tree. Also, same question about bounding box of the scene but for photon mapping. How should one find a bounding box from the pov of the light when infinite planes are involved?

• virtual machines and cryptography

  - by Unknown

  I suspect I'm a bit offtopic with the site mission, but it seems me more fitting for the question than stackoverflow i'm in preparing to create a vm with sensible data (personal use, it will be a web+mail+... appliance of sorts), i'd like to protect the data even with cryptography; the final choice have to be cross-platform for the host basically, I have to choose between guest system-level cryptography (say, dm-crypt or similar) or host level cryptography with truecrypt. do you think that the "truecrypt-volume contained virtualized disks" approach will hit the i/o performance of the vm badly (and therefore dm-crypt like approaches into the vm would be better), or is it doable? I'd like to protect all the guest data, not only my personal data, to be able to suspend the vm freely without worrying for the swap partition, etc

• Byte Size Tips: How to Show Google / Gmail Contacts in the OS X Contacts App

  - by The Geek

  The Contacts app on OS X isn’t very interesting, but if you can use it to display your Gmail contacts, it’ll get a little bit better. Luckily it’s pretty easy to add your Google / Gmail contacts, but you’ll have to click the mouse a few times and maybe poke at the old keyboard once or twice to type in your email address and password. It’s worth noting that if you set up Gmail in the Mail app you shouldn’t have to do this. Since we prefer Gmail in a browser, that’s why we’re writing this. Or just because we’re procrastinating the book editing that we’re supposed to be doing. Don’t judge. Start by opening the Preferences for the Contacts app by heading up to the Menu bar. Go to Accounts and then click the + sign to add a new one. Choose CardDAV for the account type, use your Gmail username and password, and put google.com as the server address. If you are using two-factor authentication, you’ll need to create a specific password for this account.

• If statement causing xna sprites to draw frame by frame

  - by user1489599

  I’m a bit new to XNA but I wanted to write a simple program that would fire a cannon ball from a cannon at a 45 degree angle. It works fine outside of my keyboard i/o if statement, but when I encapsulate the code around an if statement checking to see if the user hits the space bar, the sprite will draw one frame at a time every time the space bar is hit. This is the code in question if (currentKeyboardState.IsKeyUp(Keys.Space) && previousKeyboardState.IsKeyDown(Keys.Space) && !skullBall.Alive) { //works outside the keyboard input if statement //{ skullBall.Position = cannon.Position; skullBall.DeltaY = -(float)(Math.Sin(MathHelper.ToRadians(45)) * 50/*39.7577*/ * time + 0.5 * (gravity * (time * time))); skullBall.DeltaX = (float)(Math.Cos(MathHelper.ToRadians(45)) * 50/*39.7577*/ * time); skullBall.Alive = true; //} } The skull ball represents the cannon ball and the cannon is just the starting point. DeltaX and DeltaY are the values I’m using to update the cannon balls position per update. I know it's dumb to have the cannon ball start at the cannons position every time the update is called but it’s not really noticeable right now. I was wondering if after examining my code, if anyone noticed any errors that would cause the sprite to display frame by frame instead of drawing it as a full animation of the cannon ball leaving the cannon and moving from there.

• Preventing possible burnout in a junior dev, or perhaps I'm not doing enough?

  - by m.edmondson

  I'm a software developer with 5 years experience over 3 companies. Within the last year a junior (brand new to the industry) has started at my current employer. I believe he is an excellent developer, who always delivers and is skilled as solving complex problems. However I'm slightly concerned that he is possibly applying himself too much for the following reasons: He begins work approximately 2 hours before most (and is expected) In his free time he has developed an application that was clearly months worth of work that is specific to our employer I and the team are completely greatful for all he is doing, and is clearly an asset to our team. However I'm worried that this is not sustainable. I can almost see that he has the same enthusiasm that I had when I began coding for work, however over the years I've realised that extra curricular work not only doesn't progress your career, but eats into your all important free time. The question I'm asking is: Should I advise him to take things a bit more slowly? Or perhaps I need to learn from him and do more for my employer out of hours?

• Cat 6 Only 100mbit speed

  - by Stu2000

  I tried two different cat6 cables directly connected between my two ubuntu machines. This one I ordered online: http://www.amazon.co.uk/gp/product/B002SQPDXS/ref=wms_ohs_product only achieves 100mbit speeds, but does appear to be supporting cross-talk (direct pc to pc), the other cat 6 cable, worked perfectly and gets the full 1gigabit speed. Both tests were performed using ftp and checking the network monitor with direct pc to pc connection. Did the product from amazon lie to me or do I need to manually set a setting somewhere in ubuntu for some cables? I had thought 10 quid for 20m of gigabit ethernet cable was a bit cheap, you get what you pay for... Regards, Stu Update: It seems that after rebooting, the device is set to 1000mbit sec when looking it up with sudo ethtool eth0 However after a while, this will drop down to just 100, after which to reset it to 1000 again, I have to reboot, and simply unpugging and re-plugging in the cable doesn't do it. I tried setting this in networking config file as suggested here: auto eth0 iface eth0 inet static pre-up /usr/sbin/ethtool -s eth0 speed 1000 duplex full but that resulted in my networking failing to start. Is there a problem with my 'auto-negotiation' or something? Can I manually override a setting to 1000mbit?

• How to host a scalable social networking app

  - by christopher-mccann

  I am in the middle of developing a social networking application for a very select user niche which could scale to a few million users. Right now I have always hosted applications on RackSpace Cloud and I have no issues with them at all - always been a really good service and never had any downtime. My question is though does anyone think that cloud computing is not the way to host scalable web apps? Or can anyone with experience of this recommend a better solution. I have always shunned trying to run big servers from my own facilities as I think it seems silly to go to the expense of bringing in big alternative power supplies and all the other necessary precautions when other companies already do this. I looked at managed hosting services but this proved to be a bit too expensive for us at the start and the scalability of it wasnt good enough - it would take a day or two to get a new server provisioned. Therefore I ended up on a cloud platform. If anyone has any recommendations or advice it would be greatly appreciated.

• Language redirect affecting pagerank and search listing?

  - by Janoszen

  Preface We have a number of sites that use the same redirect mechanism across the board. We recently transitioned one site from non-localised to localised and detected that the Google+ integration doesn't show up on the search results any more AND the PageRank is gone from 2 to 0. How the redirect works If the UA sends a cookie (e.g. lang=en), redirect the user to /language (e.g. /en) If the UA is a bot (.*bot.*), redirect to /en If the Accept-Language header contains a usable, non-English language, redirect to /language (English is the default on many browsers in non-English regions) If there is a valid GeoIP lookup and the detected region is linked to a supported language, redirect to /language Redirect to /en We do of course on all pages have the proper markup to indicate the alternate language: <link hreflang="de" href="/de" rel="alternate" /> As far as we can tell, we follow all publicly available guidelines from Google, so we are a bit at odds if this is a bug in Google or we have done something wrong. Question Does not having content on the root URL of a domain adversely affect search engine rankings and if yes, how does one implement a proper language redirection?

• Windows 7 admin denied access to taskmgr, system32 dir

  - by DotNet Zebra

  I have a Windows 7 (32-bit) box with 2 users, both admins (my wife and I are both developers). My admin account was created during Windows setup, hers was created later. Both accounts are in the same groups, yet we have VERY different permissions. In the beta and RC, both accounts worked identically (RC to RTM was a fresh install on this box, not an upgrade). I have a C:\bin folder with the sysinternals utilities and a bunch of other stuff. Running anything in there or in system32 just works on my account, on hers I get access denied errors (cannot access file or path). If I right click and try Run As Administrator, I still get the same thing!!!

• Upgrade from Linux Mint 12 to Kubuntu 12.04?

  - by MountainX

  Is there an "easy" way to "upgrade" my existing Linux Mint 12 install to Kubuntu 12.04 beta 2? I know I could reinstall. Usually I would do a clean install to avoid unexpected issues. But in this case, I don't have time to reconfigure everything from my printers to my installed software, so I am looking for the quick/easy way, but I also want to avoid big risks of an upgrade gone wrong. I'm hoping to just change some repos and run a few commands from the terminal. I don't mind editing a few config files as long as I can find good HOWTOs. But I don't want to be the pioneer (arrows in back). I'm hoping someone has done this before and has a set of steps. For context, I recently installed KDE 4.8 SC onto Kubuntu 11.10 using PPAs. This was on another computer. That wasn't a problem. But I decided to do a fresh install of Kubuntu 12.04 later. I like it well enough that I want to change my other computer from Linux Mint 12 to Kubuntu. (I'm going all-in with KDE. It's now my desktop of choice.) This Linux Mint upgrade will be a move from Gnome and MGSE to KDE, so that will probably complicate things at bit compared to something like upgrading Kubuntu 11.10 to KDE 4.8. References: http://www.psychocats.net/ubuntu/kde Is it safe to install Kubuntu-desktop in 11.10?

• What prevents Windows from entering standby?

  - by Arne

  Is there a tool or method to find out, what prevents Windows Vista 32 bit from entering the standby mode? My home pc is set to standby after a certain time of inactivity. But quite often it just stays awake and I have know idea why. I know of things that will keep it awake and already checked devices and network to no avail. I suspect there is some application or service that tells the os to stay active and I hope there is some tool to find the culprit.

• Collision Detection for a 2D RPG

  - by PHMitrious

  First of all, I have done some research on this topic before asking, and I'm asking this question as a mean to get some opinions on this topic, so I don't make a decision only on my own, but taking into account other people's experience as well. I'm starting a 2D online RPG project. I am using SFML for graphics and input and I'm creating a basic game structure and all for the game, creating modules for each part of the game. Well, let me get to the point I just wanted to give you guys some context. I want to decide on how I'm going to work with collision detection. Well I'm kinda going to work on maps with a tile map divided in layers (as usual) and add an extra 2 layers - not exactly in the map - for objects. So I'll have collisions between objects and agents (players - npcs - monsters - spells etc) and agents and tiles. The seconds one can be easily solved the first one need a little bit of work. I considered both creating a basic collision test engine using polygons and a quadtree to diminish tests since I'm going to be working with big maps with lots of objects - creating both a physical and graphical world representation. And I also considered using a physics engine like Box2D for collision tests. I think the first approach would take more work on my part but the second one would have the overhead of using a whole physics engine for just collision detection and no physics. What do you guys think ?

• Inserting Keynote slides into a Pages document

  - by Ian Turner

  I have a number of training documents which are formed from a word processor file and a slideshow. I'd like to be able to keep them together ideally by inserting the slides from Keynote into Pages. Is there any way of doing this quickly. So far I have tried Applescript with little success, I can drag and drop the slides one at a time but it is a bit slow and I've tried turning the slideshow into and dragging it into Pages but this only pulls in the first slide. Does anyone have any better ideas?

• Set up ad hoc wireless connection between Windows Vista and Mac OS X

  - by Skarab

  I have the following problem - Windows Vista does not connect to adhoc wireless network created on my Macbook. I have tried to create secured (with 40 bit key) and unsecured network but Windows Vista still has problems to connect. Windows VISTA informs me -- after 5 minutes of attempts - that setting up the connection -- with my adhoc network -- took too much time. My question: do I need to configure some settings on Vista to connect it to my Macbook? Maybe it is a problem with DHCP?

• Why can't I create an Alias Resource Record Set for an EC2 instance

  - by praterade

  I have been working with AWS for over a year, setting up EC2 instances, domains, ELBs, etc. When I want to assign a subdomain to an EC2 instance, I have to create an elastic IP (that I pay for), then assign a CNAME record to that elastic IP. When I want to assign a subdomain to an ELB (load balancer) instance, I just create an alias resource record set to the ELB. I've read over the docs and don't understand why AWS doesn't support aliasing to instances. Am I missing a key concept here? Wouldn't it be simpler to just alias EC2 instances and skip the whole elastic IP bit?

• 12.04, nvidia-settings makes one of my dual monitors grey and useless, disables network

  - by Kerrick

  I'm running Ubuntu 12.04 64-bit, Precise Pangolin, with a PNY GTS 250 1GB video card and a monitor plugged into each of the DVI ports. I'm using the proprietary drivers (post-release updates). If I set anything to do with Separate X Screens up in nvidia-settings (and write it to xorg.conf and reboot), my second monitor has a grey background, no menu bar, no ability to have a window on it, the second monitor doesn't get picked up in a screneshot, and if I move my mouse cursor to it it's an ugly black X. Plus, my network is unable to connect to anything. If I subsequently delete /etc/X11/xorg.conf and reboot, everything goes back to working, albeit with a single monitor activated. If I set anything to do with TwinView up in nvidia-settings, my second monitor starts working, but it isn't seen as a second monitor by Ubuntu, so I can't apply color calibration to it separately. Plus, my mouse gets "caught" between the monitors every time I try to move my cursor between the two. What gives? If it helps, this is the xorg.conf that nvidia-settings generates for Separate X Screens.

• how to offer subdomain hosting with bandwidth calculation per user

  - by Ke

  Hi, Im a php developer and I would like to offer subdomain hosting,but need also to be able to calculate bandwidth for each subdomain. For the subdomains creation I will use catch-all and wildcards etc to easily set these up. The one thing im a bit stumped on is how to calculate bandwidth for each subdomain, is this possible within php? or are there better solutions for this perhaps using folders or something? Also a script will be loaded under the subdomain, this will vary per user. Is it worth giving each user a new folder and their own script, or more easy to manage one script for all users? Any considerations here? Cheers Ke

What i really need is to configure procmail to use rules stored in mysql database. How i can do this?

But i have completely no i idea how to use php script as a rule and then use its return value.

• Google analytics - drop in traffic

  - by Andy

  Bit of a general question here. We are in the process of converting a number of our clients from older web sites to new ones. The problem we are getting, and sorry for being so general here, is we are getting a sharp decline in traffic as reported on Google Analytics. It's not a gradual decline, it seems to hit almost as soon as the new site goes live. I've just got a few questions to see if there is something we are doing wrong: a) We are using the same analytics accounts going from old to new site. Is this a bad idea? b) The actual analytics code is integrated into the pages using a server-side include. IS this a bad idea? c) We structure our sites differently to our old site. IE. The old sites would pretty must have all the web pages in the root directory, and hyperlinks would be linked to the page files: EG. <a href="somepage.aspx">Link</a> Our new sites now have a directory structure that pretty much reflects the navigation structure, and hyper links link to the pages directory instead of the actual page: EG. <a href="/new-items/shoes/">New shoes</a> Is this a bad idea. I'm really searching for a needle in a haystack here. Would appriciate any help or advice as to why we are getting such a sharp and sudden drop in traffic. Again, so this is such a general question. Thanks in advance.
