  • Calling all developers building ASP.NET applications

    - by Laila Lotfi
    We know that developers building desktop apps have to contend with memory management issues, and we’d like to learn more about the memory challenges ASP.NET developers are facing. To be more specific, we’re carrying out some exploratory research leading into the next phase of development on ANTS Memory Profiler, and our development team would love to speak to developers building ASP.NET applications. You don’t need to have ever used ANTS profiler – this will be a more general conversation about: - your current site architecture, and how you manage the memory requirements of your applications on your back-end servers and web services. - how you currently diagnose memory leaks and where you do this (production server, or during testing phase, or if you normally manage to get them all during the local development). - what specific memory problems you’ve experienced – if any. Of course, we’ll compensate you for your time with a $50 Amazon voucher (or equivalent in other currencies), and our development team’s undying gratitude. If you’d like to participate, please just drop me a line on [email protected].

  • Oracle SOA Suite 11g Administrator's Handbook

    - by Antony Reynolds
    SOA Administration Book I have just received a copy of the “Oracle SOA Suite 11g Administrator's Handbook” so as soon as I have read it I will let you know what I think.  In the meantime the first thing that struck me was the author credentials, although I have never met either of them as I remember, I have read Admeds blog postings and they are a great community resource, so immediately I am well disposed towards the book.  Similarly Arun is an employee of my friend and co-author Matt Wright, and I have heard good things about him from Rubicon Red people. A first glance at the table of contents looks encouraging, I particularly like their approach to performance tuning where they give a clear concise explanation of the knobs they are using. More when I have read more.

  • Heading Out to Oracle Open World

    - by rickramsey
    In case you haven't figured it out by now, Oracle reserves an awful lot of announcements for Oracle Open World. As a result, the show is always a lot of fun for geeks. What will the Oracle Solaris team have to say? Will the Oracle Linux team have any surprises? And what about Oracle hardware? For my part, I'll be one of the lizards at the OTN Lounge with the OTN crew, handing out t-shirts to system admins and developers, or anyone who is willing to impersonate one. I understand, not everyone can have the raw animal magnetism of a sysadmin, or the debonair sophistication of a C++ developer, so some of you have no choice but to pretend. I won't judge. I'll also be doing video interviews of as many techie people as I can corner. I've got more than 30 interviews already scheduled. Most of them will be 3-5 minutes long. I'll be asking our best technical minds what's cool about their latest technologies and what impact it will have on system admins or system developers. I'll be posting those videos here: Find OTN Systems Videos from Oracle Open World Here! We've got some great topics in mind. A dummies guide to hardware-assisted cryptography with Glenn Brunette. ZFS deduplication. The momentum building around Oracle Solaris 11, with Lynn Rohrer, plus conversations with partners who have deployed Oracle Solaris 11. Migrating to Oracle Database with SQL Developer. The whole database cloud thing. Oracle VM and, of course, Oracle Linux. So even if you can't be part of the fun, keep an eye out for the videos on our YouTube channel. - Rick Website Newsletter Facebook Twitter

  • Boot-up hangs unless I manually select the kernel in the bootloader

    - by The Photon
    In my stock Ubuntu install (forgot which critter its named for, about one year old), I am able to boot up normally only if I manually select the kernel in the bootloader (Grub). If I step away and it boots from the default, the system will hang with the word "Ubuntu" on a graphics screen and a few white/red blinking dots beneath it. umb@digdug:~$ uname -a Linux digdug 2.6.32-42-generic #95-Ubuntu SMP Wed Jul 25 15:57:54 UTC 2012 i686 GNU/Linux Synaptics says I have 'grub-pc' version 1.98-1ubuntu-13 installed. My grub.cfg does have default="0" which I would expect to make the default be the first kernel shown in the selection screen. The system is a laptop with an i7 processor, and I have had trouble with some kernels not being able to boot at all in the past, and power management is not working perfectly, but I have not had problems booting the latest kernel (2.6.32-42) if I select it manually in Grub. Any idea what is going on here and how can I fix it so that I can re-boot unattended?

  • Application development : method to manage backgound process

    - by Simon Dubois
    I am developing an application with different behavior depending on the arguments : - "-config" starts a Gtk window to change options, start and close the daemon. - "-daemon" starts a background process that does something every X minutes. I already know how to use fork/system/exec etc... But I would like to know the main logic of such application to : - restart or refresh the daemon when configuration change. - keep only one instance of the daemon. I have red that killing the daemon to restart it is not a clean way to do. How other applications do ? (ubuntuone, weather forecast, rss feed working with notification area) Thanks for your help. PS : I don't want to create a system-wide daemon, just a user application with a background process.

  • How to add a sound that an enemy AI can hear?

    - by Chris
    Given: a 2D top down game Tiles are stored just in a 2D array Every tile has a property - dampen (so bricks might be -50db, air might be -1) From this I want to add it so a sound is generated at point x1, y1 and it "ripples out". The image below kind of outlines it better. Obviously the end goal is that the AI enemy can "hear" the sound - but if a wall is blocking it, the sound doesn't travel as far. Red is the wall, which has a dampen of 50db. I think in the 3rd game tick I am confusing my maths. What would be the best way of implementing this?

  • Using EPEL repos with Oracle Linux

    - by wcoekaer
    There's a Fedora project called EPEL which hosts a set of additional packages that can be installed on top of various distributions such as Red Hat Enterprise Linux, CentOS, Scientific Linux and of course also Oracle Linux. These packages are not distributed by the distribution vendor and as such also not supported by the vendors (including Oracle) however for users that want to pick up some extras that are useful, it's very easy to do this. All you need to do is download the EPEL RPM from the website, install it on Oracle Linux 5 or Oracle Linux 6 and run yum install or yum search to get the packages. example : # wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm # rpm -ivh epel-release-6-5.noarch.rpm # yum repolist Loaded plugins: refresh-packagekit, rhnplugin repo id repo name status epel Extra Packages for Enterprise Linux 6 - x86_64 7,124 The folks that build these repositories are doing a great job at adding very useful packages. They are free, but also unsupported of course.

  • CSS specificity: Why isn't CSS specificity weight of 10 or more class selectors greater than 1 id selector? [migrated]

    - by ajc
    While going through the css specificity concept, I understood the fact that it is calculated as a 4 parts 1) inline (1000) 2) id (100) 3) class (10) 4) html elments (1) CSS with the highest rule will be applied to the corresponding element. I tried the following example Created more than 10 classes <div class="a1"> .... <div class="a13" id="id1"> TEXT COLOR </div> ... </div> and the css as .a1 .a2 .a3 .a4 .a5 .a6 .a7 .a8 .a9 .a10 .a11 .a12 .a13 { color : red; } #id1 { color: blue; } Now, even though in this case there are 13 classes the weight is 130. Which is greater than the id. Result - JSFiddle CSS specificity

  • Very Cool &ndash; Miami 311 System for tracking citizen service requests (Windows Azure, Silverlight

    - by Jim Duffy
    Having grown up in South Florida this short, but very enlightening, video explaining how the City of Miami has implemented a 311 citizen service request system using Windows Azure, Silverlight and Bing Maps definitely caught my attention. Miami311 The Miami311 System is a Windows Azure/Silverlight-based solution which enables City of Miami citizens report and track issues reported to city management. The system uses Bing Maps to plot the location and relevant information about each issue reported. Citizens now have the ability to easily see the status of the issue without having to call the city office. What I found interesting were a couple of benefits that a metropolitan area such as Miami can take advantage of in Windows Azure cloud-based solution. For the city of Miami, both benefits center around the weather. Of course the threat of a hurricane is a real issue in South Florida and what better way to make sure your site stays up during a hurricane then to have the site hosted far away from the eye of the storm. Using a Windows Azure cloud-based architecture the City of Miami is able to host the application within the Microsoft data centers safely away from any hurricane passing through South Florida. The second benefit is the inherent scalability of a Windows Azure based solution. During a severe weather event like thunderstorms or even worse, a hurricane, downed trees and power lines are a commonly reported problem. Being able to quickly scale up the computing resources required to handle the spike in citizens reporting these types of problems on the site is a huge benefit. Once the weather event has passed and downed tree reports begin to subside they can quickly reverse the process and scale the system back down to pre-storm levels. It’s kind of day-to-day kind of stuff but very cool stuff nonetheless. Have a day. :-|

  • Find non-ascii characters from a UTF-8 string

    - by user10607
    I need to find the non-ASCII characters from a UTF-8 string. my understanding: UTF-8 is a superset of character encoding in which 0-127 are ascii characters. So if in a UTF-8 string , a characters value is Not between 0-127, then it is not a ascii character , right? Please correct me if i'm wrong here. On the above understanding i have written following code in C : Note: I'm using the Ubuntu gcc compiler to run C code utf-string is xvab c long i; char arr[] = "xvab c"; printf("length : %lu \n", sizeof(arr)); for(i=0; i<sizeof(arr); i++){ char ch = arr[i]; if (isascii(ch)) printf("Ascii character %c\n", ch); else printf("Not ascii character %c\n", ch); } Which prints the output like: length : 9 Ascii character x Not ascii character Not ascii character ? Not ascii character ? Ascii character a Ascii character b Ascii character Ascii character c Ascii character To naked eye length of xvab c seems to be 6, but in code it is coming as 9 ? Correct answer for the xvab c is 1 ...i.e it has only 1 non-ascii character , but in above output it is coming as 3 (times Not ascii character). How can i find the non-ascii character from UTF-8 string, correctly. Please guide on the subject.

  • Thomson TG782T ADSL2+ modem loses network connection

    - by squashbuff
    I am using an ubuntu 10.04 server (running on a Lenovo Thinkpad notebook) as my webserver. It is performing well in terms of handling the traffic etc. However my internet connection is ADSL2+ (using Thomson TG782T modem-router) and if the modem is reset, then my server loses network connection. The networkmanager icon shows a red exclamation mark showing that is has no connection. But as soon as I click on it and tell it to connect to eth0, the connection is back on. It must be something that networkmanager is failing to do and because of this, the reliability of my webserver is suffering. Any advice on how this can be fixed?

  • How to get a point to the left/right of a vector

    - by MulletDevil
    I have a position vector of a point in space and a quaternion for it's rotation. What i'm trying to calculate is a point too the left and a point to the right. I have the position and rotation(quaternion) of the red dot. What I want is to get the position of the green dots. I have a float value for the distance I want these points to be. With only the position and rotation is it possible to get a unit direction vector pointing left/right which I can multiply by my float value? Edit: I also know the original direction vector.

  • Implementing a JS templating engine with current PHP project

    - by SeanWM
    I'm currently working on a PHP project and quickly realizing how useful a templating engine would help me. I have a few tables whose table rows are looped out via a PHP loop. Is it possible to use just a JS templating engine (like Handlebarsjs) to also work with these tables? For example: $arr = array('red', 'green', 'blue'); echo '<table>'; foreach($arr as $value) { echo '<tr><td>' . $value . '</td></tr>'; } echo '</table>'; Now I want to add a column via an ajax call using a JS templating engine. Is this possible? Or do I have to use a templating engine for both server side and client side?

  • DX10 sprite and pixel shader

    - by Alex Farber
    I am using ID3DX10Sprite to draw 2D image on the screen. 3D scene contains only one textured sprite placed over the whole window area. Render method looks like this: m_pDevice-ClearRenderTargetView(...); m_pSprite-Begin(D3DX10_SPRITE_SORT_TEXTURE); m_pSprite-DrawSpritesImmediate(&m_SpriteDefinition, 1, 0, 0); m_pSprite-End(); Now I want to make some transformations with the sprite texture in a shader. Currently the program doesn't work with shader. How it is possible to add pixel shader to the program with this structure? Inside the shader, I need to set all colors equal to red, and multiply pixel values by some coefficient. Something like this: float4 TexturePixelShader(PixelInputType input) : SV_Target { float4 textureColor; textureColor = shaderTexture.Sample(SampleType, input.tex); textureColor.x = textureColor.x * coefficient; textureColor.y = textureColor.x; textureColor.z = textureColor.x; return textureColor; }

  • What algorithms would suit image colour summarization? [on hold]

    - by codecowboy
    I would like to analyse a set of hundreds of thousands of product images (clothing, electronic goods etc) and retrieve the dominant colours in each. I'm only interested in the top 3 or 4 colours. The aim is to achieve a degree of certainty that x image is mostly red or image y is mostly orange and blue. The images are likely to be colour jpegs of reasonable quality and approximately 100kb in size. I would like to use C# and the solution should run on a Linux server, preferably using open source libraries. What image processing algorithms or techniques might help me achieve this?

  • Why does my health bar disappear whenever my character takes amage?

    - by iQue
    Im making health bar for my game that looks like this: public void healthBar(Canvas canvas) { float healthScale = happy.getHP() / happy.getMaxHP(); Rect rect = new Rect(20, 20,(120 * (int)healthScale), 40); Paint paint = new Paint(); paint.setColor(Color.RED); canvas.drawRect(20, 20, 220 * healthScale, 40, paint) } this is called every time my game renders. When the game starts it's where I want it, but as soon as my character (happy) takes any damage, it dissapears. And I know that his hp only gets subtracted by 5 every time he gets hit. So this should not happen? example: @Startup: happy.getHP() == 100, happy.getMaxHP == 100. when damaged HP -=5, -> happy.getHP() == 95 -> healthscale == 0,95 -> 220 * 0,95 == new width for Rect(?)

  • Efficient way to calculate "vision cones" on 2D tile map?

    - by OverMachoGrande
    I'm trying to calculate which tiles a particular unit can "see" if facing a certain direction on a tile map (within a certain range and angle of facing). The easiest way would be to draw a certain number of tiles outward and raycast to each tile. However, I'm hoping for something slightly more efficient. A picture says a thousand words: The red dot is the unit (who's facing upwards). My goal is to calculate the yellow tiles. The green blocks are walls (walls are between tiles, and it's easy to check if you can pass between two tiles). The blue line represents something like the "raycasting" method I was talking about, but I'd rather not have to do this. EDIT: Units can only be facing north/south/east/west (0, 90, 180, or 270 degrees) and FoV is always 90 degrees. Should simplify some calculations. I'm thinking there's some sort of recursive-ish/stack-based/queue-based algorithm, but I can't quite figure it out. Thanks!

  • Skype does not save user configuration

    - by varsketiz
    On Ubuntu 10.10, I have recently started to experience this problem: For some reason Skype won't save any settings except "Sign in on startup". When Skype starts and tries to sign in it is unsuccessful (it shows incorrect password, in red) every time (I have provided the correct password). I always have to click to show contacts in groups, it does not remember it. Every time I have to go to options and update some notification settings. I know all these things should be "remembered" by Skype - this problem started only recently. I don't recall fiddling with any permissions that could have likely caused that. Do you know what the problem might be? I uninstalled (marking for complete configuration removal) and re-installed Skype, but it still remembers my username (why??). Can I find Skype configuration files on the filesystem somewhere and change permissions for them - or even better - edit the files to set what I want?

  • How can I get wireless working on an HP-Mini 110-3150?

    - by jfmessier
    I just got an HP Mini 110-3150, and booting from an external hard disk with Ubuntu 10.10 works all fine, except that there is no wireless detected. I noticed that the Wireless indicator is red under Ubuntu, but is enabled under whatever Windows 7 I got on it. So, I understand that it may not get detected at all by Ubuntu at startup time, and there is no manual switch that I can simply slide to turn on/off. How can I get the Wireless device turned ON by default at startup time, and is there any special driver I need to install (proprietary or not) to get it working ? Merci :-) Update: When actually installing on the computer, as a new install, the NIC is not detected at first, but upon restarting, I get a notification of a closed driver available for the wireless. Once installed, updated and restarted, it works fine.

  • SQL Excursions

    - by Grant Fritchey
    Not everyone likes boats. Some people like hanging out, on dry land, maybe sipping a good wine. Interested in doing that AND learning some new stuff about SQL Server? Then you might want to check out SQL Excursions. Denny Cherry (blog|twitter), MVP and terribly sharp individual, has organized this new venture to supply small group training in combination with travel to interesting, and let's face it, comfortable, places. The first trip is already set for Napa Valley. The training will be by Denny and MVP, author, and all round great guy, Thomas LaRock (blog|twitter). Seats for this unique event are going fast. I'd suggest signing up soon. Oh, and did I forget to mention that Red Gate is sponsoring dinner at a fine restaurant? Well, consider it mentioned. Seriously, nice wine, great training, beautiful scenery, networking, all in one place. What are you waiting for?

  • Azure Search Preview

    - by Greg Low
    One of the things I’ve been keeping an eye on for quite a while now is the development of the Azure Search system. While it’s not a full replacement for the full-text indexing service in SQL Server on-premises as yet, it’s a really, really good start. Liam Cavanagh, Pablo Castro and the team have done a great job bringing this to the preview stage and I suspect it could be quite popular. I was very impressed by how they incorporated quite a bit of feedback I gave them early on, and I’m sure that others involved would have felt the same. There are two tiers at present. One is a free tier and has shared resources; the other is currently $125/month and has reserved resources. I would like to see another tier between these two, much the same way that Azure websites work. If you have any feedback on this, now would be a good time to make it known. In the meantime, given there is a free tier, there’s no excuse to not get out and try it. You’ll find details of it here: http://azure.microsoft.com/en-us/documentation/services/search/ I’ll be posting more info about this service, and showing examples of it during the upcoming months.
