  • What is the best way to create derived properties

    - by user342788

The employee has an attribute salary. How best to have a attribute at the level of division which is derived from the salary attribute. For example average salary or maximum salary. I would need those attributes to sort the list of departments.

  • Setting up a reverse proxy [on hold]

    - by mrwooster
    I am looking for the best solution for setting up a very low maintenance reverse proxy for a production website (example.com). The setup is as follows: A blog with will be hosted on heroku, and will reside at example.com/blog A static info page which will be hosted on S3 and will reside at example.com/signup A dynamic content management system, provided and hosted by an external vendor which will respond to requests for any other pages. The two solutions which come to mind are: Use HAProxy Ask the external vendor to reverse proxy requests for /blog and /signup The obvious solution would be to use HAProxy, but, if at all possible, I would like to avoid having to setup and maintain another server (especially such a critical one). I came across a company called Snapt which offers hosted HAProxy solutions, but its more geared towards load-balancing than reverse proxying. Option 2 is a possibility, but gives us very little control over changes and configuration. I see a lot of sites hosting blogs on /blog so this must be fairly common practice, am I missing an obvious solution?

  • How to deploy an application with firewall permissions on Mac?

    - by user264878
    I've bundled a jar file as a mac application using jar bundler. I'm now trying to create an installer for this app so that: 1) The application will be placed in the applications folder 2) The application is added to the list of permissible apps in Mac Application Level Firewall Also, I have several example files I would like to include with this application - what is the best way to make these available to the user. Someone suggested I have the mpkg file launch a dmg file which would contain these files, but this seems circuitous. Thanks

  • What does it mean to flush a socket?

    - by User4748402
    I don't really know much about sockets except how to read and write to them as if they were files. I know a little about using socket selectors. I don't get why you have to flush a socket, what's actually happening there? The bits just hang out somewhere in memory until they get pushed off? I read some things online about sockets, but it's all very abstract and high level. What's actually happening here?

  • Static member class - declare class private and class member package-private?

    - by Helper Method
    Consider you have the following class public class OuterClass { ... private static class InnerClass { int foo; int bar; } } I think I've read somewhere (but not the official Java Tutorial) that if I would declare the static member classes attributes private, the compiler had to generate some sort of accessor methods so that the outer class can actually access the static member class's (which is effectively a package-private top level class) attributes. Any ideas on that?

  • How To Prevent Processes From Starting?

    - by Rob P.
    I'm toying around with a very simplistic sort of process-monitor. Currently, it gets a list of the running processes and attempts to kill any process that is not white-listed. What I'm looking for is a way to prevent a process from starting that isn't on the white-list. If that's possible. My knowledge level in this area is pretty non-existent and my Google-fu only returns websites discussing Process.Start() :( Can anyone point me in the right direction?

  • More RAM vs. more servers [closed]

    - by user357972
    I was recently asked "Do you know when to decide between going for more RAM or more servers?" (in the context of scaling data mining applications). I had no idea, so what are some ways to decide? I have very little knowledge of architecture and scaling (my understanding of computer memory and what a server does is limited to the high-level basics), so tips on learning more about these things in general are also very welcome.

  • My microphone is too quiet (seems to be connected with Skype)

    - by AmitM9S6
    I've been chatting with skype for a long time.. and I don't know why, but for X time it's fine, and then it's too quiet.. Here how it goes : I'm booting the PC - getting into a skype call with friends - talking with friends on skype - (everything goes well) - Closing the skype call - Going back to a skype call like a hour after -. They can't hear me well, I have to shout so they'll hear me, and in the settings, it's on 100% + 30 DECIBELS, so I can't raise it higher... and if I'll re-boot my PC, it'll be well until I'll close the skype call again.. Every time I'm skyping with friends well, and then when I close the call and come back after a while, they hear me really low(volume).. I've been trying to fix this problem for about 2 months! If you'll be able to help me, I'd be so happy. (btw It's connected not through USB, but through a microphone connection and headphone connection...) Also, I got Windows 7..

  • Unable to use strong encryption

    - by user224299
    So I am exploring Apache to create a simple example: the default page and a directory "secure". I everyone to be able to access the server but, when one wants to access the "secure" directory, I the connection to use strong encryption. I am using apache2.4. However this is not working and I don't know why! I have done just like in the Apache tutorial: LoadModule ssl_module /usr/lib/apache2/modules/mod_ssl.so <VirtualHost *:443> SSLEngine on SSLCertificateFile /home/vitorpereira/Desktop/cert.cer SSLCertificateKeyFile /home/vitorpereira/Desktop/key.key </VirtualHost> SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL <Location /var/www/html/secure> SSLCipherSuite HIGH:!aNULL:!MD5 </Location> But this does not work :/ And, I can access the secure folder with http but when I write https, it says not found!

  • Should I implement IDisposable here?

    - by dotnetdev
    My method which calls SQL Server returns a datareader but because of what I need to do (return the datareader to the calling method which is in page code-behind), I can't close the connection in the class of the method which calls sql server, so I have no finally or using blocks. Is the correct way of disposing resources to make the class implement IDisposable? Or from the caller, explicitly dispose the unmanged resource (class-level fields)? Thanks

  • SQL Server 2008 (64-bit)

    - by Grace09
    I have transaction log backup failures randomly. SQL Server Log says 'Memory constraints resulted reduced backup/restore buffer sizes. Proceding with 6 buffers of size 64KB.', and the SQL Server Agent Error Log has quite a few errors like 'Unable to start Job Manager thread for job xxx', '[298] SQLServer Error: 768, Client unable to establish connection [SQLSTATE 08001]', [298] SQLServer Error: 768, SSL Provider: Not enough memory is available to complete this request [SQLSTATE 08001]'. I am really low on the memory? It has total of 32 GB, but I set maximum to 20. Task manager shows it is using 99% of physical memory. Memoryclerk-sqlbufferpool has 32GB for the Virtual Memory Reserved, and 20 GB for the Virtual Memory Committed. From the perfmon, SQLServer:Memory Manager/Total ServerMemory shows 21GB of memory in use, that's what I set the maximum to. I don't where the rest of memory go. Can anyone advice? Thanks in advance.

  • Targeting all subclassed CCSprites (cocos2d)

    - by Joethemonkey101
    I'm working on a method to end the level, but to do so, I have to see that all of the enemy character have been killed. If my enemies are CCSprites, how do I make a method that detects if all of them are dead? I'm tracking their health with an int called enemyHp. For example, this is an if statement I made to remove the enemy if (enemy.enemyHp <= 0) { To recap - I want to make a method that detects when all enemies have been killed. Thanks

  • How to achieve a specific fraction(say 80%) of the cpus and balanced over them

    - by swellfr
    Hi, I was wondering if it would be possible to run app not at 100% of the cpu but at a specific amount of the cpus. I see different usage of this , we can better balance concurrent application ( we may want to have balance app 50% to have fair apps/agent/... ) i was also wondering if the power consumption would not be better if the cpus doesnt run at full throttle but at some lower level( say 80% ) What are your thoughts Thx examples are welcomed :)

  • SFML: Generate a background image

    - by BlackMamba
    I want to generate a background, which is used in the game, on every instance of the game based on certain conditions. To do so, I'm using a sf::RenderTexture and a sf::Texture like this: sf::RenderTexture image; std::vector<sf::Texture> textures; sf::Texture texture; // instantiating the vector of textures and the image not shown here for (int i = 0; i < certainSize; ++i) { if(certainContition) { texture.setTexture("file"); texture.setPosition(pos1, pos2); } else { ... } image.draw(texture); } The point here is that I draw single textures on a sf::RenderTexture, but because textures always are on the graphic cards memory, I can't exceed a certain map size which I have to. I also considered using an sf::Image, but I can't find a way to draw an image (i.e. a texture) to it. The third way I found was using an sf::VertexArray, but this seems to be a bit too low-level for my rather simple purposes. So is there a common way to dynamically generate a background image based on other existing images?

  • Speaker at developer conferences and user group meetings

    Catching up on a couple of sessions I did in the past. This article gives an overview of some of my activities. Mainly at the annual German Visual FoxPro Developer Conference also known as SQL-Server & ASP.NET Conference in Frankfurt. The below listed entries are excerpts from the original Conference Coverage documents you'll find on UniversalThread. German Visual FoxPro Developer Conference 2002 (1 session - Vendor session about Active FoxPro Pages 3.0) German Visual FoxPro Developer Conference 2003 (2.5 sessions - Visual FoxPro running on Linux) German Visual FoxPro Developer Conference 2004 (4 sessions - 2x Active FoxPro Pages, VFP on Linux, and VFP using additional databases) German Visual FoxPro Developer Conference 2005 (4 sessions - RegEx, XML, XSLT, and using free (as in beer) development tools) German Visual FoxPro Developer Conference 2006 (3 sessions - .NET interop via COM, writing own CLR host in VFP, and Active FoxPro Pages) Furthermore, I did a couple of (hopefully) interesting sessions at various user group meetings in Speyer and Stuttgart. A more comprehensive list is available under Presentations (in German language). And last but not least, back in May 2005 Microsoft Germany invited me to host a WebCast for MSDN on how to use 'Visual FoxPro mit Visual Studio 2005'. Unfortunately, I was too unexperienced and too nervous (first time ever), we experienced technical issues with the microphone, and the obviously low quality of recording demanded to replace it by a whole series on Visual FoxPro 9.0. The webcast covered the same topics I already described in other articles here on my blog. Despite the desaster I'd like to thank Ralf Westphal for his kind words afterwards - I really felt bad. Eventually, you might ask yourself why it stopped by the end of 2006... Well, new chapter in my life: Mauritius!

  • Wired PS/2 Keyboard and Mouse do not work in 12.04 Live CD or after fresh 12.04 install - Foxconn D270S Atom Motherboard

    - by david krajewski
    My Wired PS/2 keyboard and mouse do not work in 12.04, either in a fresh install or from the Live CD. A USB keyboard and mouse will work. The PS/2 keyboard and mouse will work using the same hardware and a fresh 10.04 Ubuntu install or a fresh Windows 7 install. The motherboard is a Foxconn D270S Atom based motherboard. This problem is specific to this motherboard and Ubuntu 12.04. So far I've tried running in the fresh 12.04 install: sudo apt-get install sudo apt-get upgrade sudo apt-get dist-upgrade After the apt-get upgraded the first time, I now get to the point where there are 0 items to be upgraded. Rebooted and still no PS/2 keyboard/mouse. I've also tried adding the following lines to GRUB at boot time (the PS/2 keyboard works in GRUB) acpi=noirq acpi=off Neither setting made any difference. The motherboard is a Foxconn D270S Atom based motherboard. Even more interestingly, 12.04 recognizes the same PS/2 keyboard and mouse on a separate Gigabyte AM3+ based motherboard. I only have this problem on this particular motherboard with Ubuntu 12.04. Any help would be appreciated. I bought this low-power motherboard specifically for the task of running Ubuntu 12.04 for the next five years... Update... I dug out an old PS/2 mouse that does not use a PS/2 to USB adapter but is directly wired for PS/2. Still no PS/2 keyboard or mouse after reboot. Again, I only have this problem with this motherboard and 12.04 Ubuntu. Other motherboards work fine with 12.04 and this motherboard works fine with 10.04. Update 2... I installed the 12.04 Server version. The text-based installer recognized the keyboard without issue, but after the first boot into the installed OS, the PS/2 keyboard would no longer respond. I tried installing Gnome on the Server install and the PS/2 mouse and keyboard don't work in Gnome either. I Opened bug #995570 for this issue
