  • How to emulate pressing the Close button from a script?

    - by Karthik
    I wanted Thunderbird to stay in the Background to notify me of incoming mails. After a bit of searching, I found this post. How to keep Thunderbird and Pidgin running on background? The solution is to install an addon so that when we close Thunderbird it just stays in the background. Now, to have thunderbird running at Start up we can just add it to Startup Applications. But, when I open my system, Thunderbird also gets opened and I have to manually press the close button everytime to make Thunderbird go into the background. The solution given in the above post for this problem is to select Minimize on start. But doing so affects the way in which Thunderbird works when invoked from the Messaging menu. So I deselected this option. But, if there is a way to emulate pressing the Close button from a script, I can just add that script to Startup Applications So is there a way to achieve this? Note : If there is a simpler way to solve my original problem of keeping Thunderbird in background please post that also. Many thanks.

  • How add cpu frequency that should be available?

    - by Andrew Redd
    I have a system with an Intel Core i7 970 that should be able to run at 3.2 GHz. I'm running ubuntu 12.04 and installed the cpufreq indicator to be able to change the governor and noticed that I only had frequencies up to 2.0 GHz available to me. I set to performance and checked with cpufreq-info cpufreq-info -c 0 cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7 8 9 10 11 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.60 GHz - 2.00 GHz available frequency steps: 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.60 GHz and 2.00 GHz.

  • Is it bad practice for services to share a database in SOA?

    - by Paul T Davies
    I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?

  • Compaq Presario CQ40 unexpected turn off

    - by CRoshanLG
    My Compaq Presario CQ40 (yeah, its pretty old) suddenly turns off after about 1/2 - 1 hour usage without any notice or warning. The power cable and adapter works fine (indicator bulbs show that power is given to the laptop), but it seems like machine suddenly plugged off from the power source. And when I try to switch it on, after the sudden turn off it simply won't turn on. I can only turn it on after letting it to rest for at least couple of hours! ** The battery has been dead for some time now, but it has been working fine on direct power supply until recently. Has anyone encountered this? and hopefully knows any cure?

    - by Sahil Malik
    SharePoint 2010 Training: more information Fellow citizens of the tech world, you’re watching a good Samaritan die. Unfortunately this is not the first time, it won’t be the last. We have seen this before, sadly we will see it again. The IT industry, is a few sharks – Oracle, Apple, Google, and yes, Microsoft, and numerous small fishes around them. 10 years ago, you saw some innovating smart engineers create instant-messaging programs. There was rapid innovation and growth in that field even though internet itself was quite nascent. Remember ICQ? Well, then came around the sharks! They offered you free versions of IM programs that in the short run were actually superior. Yahoo messenger, MSN, AIM and then later on google.  Innovation in IM was pretty much stand still until a new contender like skype decided to marry IM with telephony. This prompted google to do the same. Of course, Skype was then purchased by Microsoft.  The situation still stands, lets take the example of Microsoft, it offers, Read full article ....

  • Netbook performs hard shutdown without warning on low battery power

    - by Steve Kroon
    My Asus EEE netbook performs a hard shutdown when it reaches low battery power, without giving any warning - i.e. the power just goes off, without any shutdown process. I can't find anything in the syslog, and no error messages are printed before it happens. I've had this problem on previous (K)Ubuntu versions, and hoped updating to Ubuntu Precise would help resolve the issue, but it hasn't. The option in the Power application for "when power is critically low" is currently blank - the only options are a (grayed-out) hibernate and "Power off". I have re-installed indicator-power to no effect. The time remaining reported by acpi is unstable, as is the time remaining reported by gnome-power-statistics. (For example, running acpi twice in succession, I got 2h16min, and then 3h21min remaining. These sorts of jumps in the remaining time are also in the gnome-power-statistics graphs.) It might be possible to write a script to give me advance warning (as per @RanRag's comment below), but I would prefer to isolate why I don't get a critical battery notification from the system before this happens, so that I can take action as appropriate (suspend/shutdown/plug in power) when I get a notification.

  • game multiplayer service development

    - by nomad
    I'm currently working on a multiplayer game. I've looked at a number of multiplayer services(player.io, playphone, gamespy, and others) but nothing really hits the mark. They are missing features, lack platform support or cost too much. What I'm looking for is a simple poor man's version of steam or xbox live. Not the game marketplace side of those two but the multiplayer services. User accounts, profiles, presence info, friends, game stats, invites, on/offline messaging. Basically I'm looking for a unified multiplayer platform for all my games across devices. Since I can't find what I'm planning to roll my own piece by piece. I plan to save on server resources by making most of the communication p2p. Things like game data and voice chat can be handled between peers and the server keeps track of user presence and only send updates when needed or requested. I know this runs the risk of cheating but that isn't a concern right now. I plan to run this on a Amazon ec2 micro server for development then move to a small to large instance when finished. I figure user accounts would be the simplest to start with. Users can create accounts online or using in game dialog, login/out, change profile info. The user can access this info online or in game. I will need user authentication and secure communication between server and client. I figure all info will be stored in a database but I dont know how it can be stored securely and accessed from webserver and game services. I would appreciate and links to tutorials, info or advice anyone could provide to get me started. Any programming language is fine but I plan to use c# on the server and c/c++ on devices. I would like to get started right away but I'm in no hurry to get it finished just yet. If you know of a service that already fits my requirements please let me know.

  • Tuning B2B Server Engine Threads in SOA Suite 11g

    - by Shub Lahiri, A-Team
    Background B2B 11g has a number of parameters that can be tweaked to tune the engine for handling high volumes of messages. These parameters are also known as B2B server properties and managed via the EM console.  This note highlights one aspect of the tuning exercise and describes the different threads, that can be configured to tune the performance of a B2B server. Symptoms The most common indicator of a B2B engine in need of a tuning is reflected in the constant build-up of messages in an internal JMS queue within the B2B server. It is called B2B_EVENT_QUEUE and can be monitored via the Weblogic server console. Whenever such a behaviour is seen, it usually results in general degradation of performance. Remedy There could be many contributing factors behind a B2B server's degradation of performance. However, one of the first places to tune the server from the out-of-the-box, default configuration is to change the number of internal engine threads allocated within the B2B server. Usually the default configuration for the B2B server engine threads is not suitable for high-volume of messaging loads. So, it is necessary to increase the counts for 3 types of such threads, by specifying the appropriate B2B server properties via the EM console, namely, Inbound - b2b.inboundThreadCount Outbound - b2b.outboundThreadCount Default - b2b.defaultThreadCount The function of these threads are fairly self-explanatory. In other words, the inbound threads process the inbound messages that are coming into the B2B server from an external endpoint. Similarly, the outbound threads processes the messages that are sent out from the B2B server. The default threads are responsible for certain B2B server-specific special tasks. In case the inbound and outbound thread counts are not specified, the default thread count also dictates the total number of inbound and outbound threads. As found in any tuning exercise, the optimisation of these threads is usually reached via an iterative process. The best working combination of the thread counts are directly related to the system infrastructure, traffic load and several other environmental factors.

  • Unity calendar lens not showing events

    - by David_G
    I'm trying to get proper/useful calendar integration into Ubuntu 12.04. I have a Google Calendar (& account) and I want to be able to use this without opening the browser. I want to get the Unity Calendar lens working, so that it shows events coming up, and it allows me a quick way to add new events. However, after installing it, it does not find any events, nor allow me to add a new event. Note that I've installed Lightning 1.4, Evolution mirror 0.2.3, Evolution, and unity-calendar lens. I've also installed Calendar-indicator. I suspect that somehow the lens is not getting the calendar information from thunderbird via evolution. A bit of searching around led me to try this command: /usr/lib/calendar-lens/calendar-lens-daemon.py. With this result: /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject Traceback (most recent call last): File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 324, in daemon = Daemon() File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 80, in init for calendar in evolution.ecal.list_calendars(): AttributeError: 'NoneType' object has no attribute 'list_calendars' Any ideas?

  • Where could Distributed Version Control Systems currently be in Gartner's hype cycle?

    - by dukeofgaming
    Edit: Given the recent downvoting (+8/-6 at this point) it was made clear to me that Gartner's lifecycle is a biased metric from a programmer's perspective. This is something that is part of a paper I'm going to present to management, and management types are part of Gartner's audience. Giving DVCS exposure & enthusiasm (that "could" be deemed as hype, or at least attacked as such), think about the following question when reading this one: "how could I use Gartner's hype cycle to convince management that DVCSs are ready (or ready-enough) for us, and that it is not just hype" Just asking if DVCSs is hype wouldn't be constructive, Gartner's hype cycle is a more objective instrument than just asking that (even if this instrument is regarded as biased). If you know any other instrument please, by all means, mention it. Edit #2: I agree that Gartner's Life Cycle is not for every technology, but I consider it may have generated enough buzz to be considered hype by some, so it maybe deserves to be at least evaluated/pondered as such by using this instrument in order to prove/disprove it to whatever degree. I'm an advocate of DVCS, BTW. I'm doing research for a whitepaper I'm writing in favor of DVCS adoption at company and I stumbled upon the concept of social proof. I want to prove that the social proof of DVCS adoption is not necessarily cargo cult and doing further research I now stumbled upon Gartner's hype cycle which describes technology maturity in 5 phases. My question is: what could be an indicator of the current location of Distributed Version Control Systems (I mean git, mercurial, bazaar, etc. in general) at a particular phase in the hype cycle?... in other (less convoluted) words, would you say that currently expectations of DVCSs are a) starting, b)inflated, c)decreasing (disillusionment), d)increasing (enlightenment) or e)stabilizing (mature) and (more importantly) why? I know it is a hard question and there is subjectivity involved, but I'll grant the answer (and the traditional cookie) to the clearest argument/evidence for a particular phase.

  • Design Application to "Actively" Invite Users (pretend they have privileges)

    - by user3086451
    I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

  • Squid traffic tunneled through VPN

    - by NerdyNick
    So what I'm trying to do is have a Squid Proxy run on 1 machine along side a VPN connection. What I want to happen is all traffic running though the Squad Proxy would run though the VPN for its outbound. ie Desktop - (Squid Proxy - VPN) The goal is to allow my desktop selective tunneling through the VPN. So that Instant Messaging and the like that do not need to run through the VPN can go through my normal traffic. Typically I would go though a SSH Proxy but currently am forced to use VPN to gain entry into the office, and a Squid proxy seemed like it might work out the easiest for what I am needing. EDIT Realize I forgot to actually state what problem I'm running into. I have the Squid setup and verified it works, but once I connect to the VPN. All requests to Squid get accepted but Squid is unable to make the request over the VPN. So the client ends up just sitting there.

  • Network Issues only on one network with a Broadcom BCM4312

    - by Ryan McClure
    My Ubuntu 11.10 laptop is having network connection issues...only on one network. I have a BCM4312 card and I'm using the proprietary driver. Whenever I connect to a network over wireless connection, I have no trouble except for one network. In my dorm, if I try to connect to the wireless network, it stays connected from anywhere to 30 seconds to 30 minutes before it will still be "connected" according to the indicator but there is no incoming/outgoing internet connection. This only happens in this building. Other networks with the same name at other buildings on my campus have no issue whatsoever. I took it to the tech department here and they keep claiming it's my laptop; but, if I can connect to other networks with absolutely no issues, why can't my laptop connect here? So, here's my question: Is it my laptop, or is it the network? As a side note, no one else that I know has issues on this network but one; she's running Windows 7 and I forget what kind of laptop it is. One of the people in my hall runs Ubuntu 12.04 and has no problem with the wireless. What do you all think of this?

  • PowerBroker (Likewise-Open) + Ubuntu 13.04 -> 13.10 Upgrade

    - by JoBu1324
    I just upgraded Ubuntu from 13.04 to 13.10, and now I can't log into Active Directory; my system is integrated using PowerBroker Identity Services (PBIS), which used to be called Likewise-Open. So far I have identified the following symptoms: I am able to log in with my credentials via ssh. The screen goes black when attempting log into my account via the login screen. I've tried leaving the domain, purging PBIS, and re-installing the latest version of PBIS. I've been trying the troubleshooting section I found here, but I haven't had any success.

  • Spotlight on an ACE: Edwin Biemond

    - by jeckels
    Edwin Biemond is an active member of the ACE community, having worked with Oracle's development tooling and database technologies since 1997. Since then, Edwin has become an expert in many of Oracle's middleware technologies as well, including WebLogic and SOA. In fact, Edwin has become so prolfic that he was named the Java Developer of the Year in 2009. Edwin hails from the Netherlands, where he is an architect at the company Amis, and is also a co-author of the OSB Development Cookbook. He's a proven expert in ADF, JSF, messaging (Edifact / ebXML), Enterprise Service Bus, web services and tuning of application servers and databases. Recently, Edwin posted a blog on the road map of WebLogic 12c, going over salient features and what the future looks like for Fusion Middleware and the Application Server areas - it's well worth a read, so give it a look. A snippet: WebLogic 12.1.3 will be the first version for many FMW 12c products like Oracle SOA Suite 12c and probably come in one big jar. 12.1.3 & 12.1.4 will add extra features and improvements to Elastic JMS & Dynamic Clusters. Elastic JMS in 12.1.3 will support Server Migration so you can’t lose any JMS messages. In 12.1.4, Dynamic Clusters will have support for auto-scaling based on thresholds based on user-defined metrics. WebLogic 12.1.4 will also have an API to control the Dynamic Clusters, this way we can easily program when to stop, start or remove nodes from a dynamic cluster. Further, Edwin is hosting a session on getting your FMW environment up and running in less than 10 minutes using popular tooling to configure and manage the many FMW components you have in your technology stack. Register now for this virtual developer day to see more. We thank Edwin for his commitment to being an ACE, his work on his blog, his social media publishing and his overall commitment to helping other technologists be even more successful with Oracle products.

  • RAM caching causes severe performance drops

    - by B T
    I have read plenty of threads on memory caching and the standard response of "large cache is good, it shouldn't effect performance", "the kernel knows best". I have recently upgraded from 12.04 to 12.10 and changed from VirtualBox to VMware Workstation and the performance differences are severe (I suspect it is because of the latter). When I am running my virtual machine the system load monitor graph shows less than 50% memory usage generally. System load indicator is showing me that the rest of my RAM is used in the cache all the time. Plain and simple this is the comparison: BEFORE Cache was very sparingly used, pretty much none of my memory usage was the cache Swappiness was 0 (caused my memory to be used first, then swap only if needed) Performance was quite good and logical RAM was used fully first, caching was minimal. I could run enough software to utilize my full 4GB of RAM without any performance degradation whatsoever Swap space was then used as needed which was obviously slower (I am on a HDD) but was still usable when the current program was loaded into memory AFTER Cache is used to fill the full 4GB as soon as my virtual machine is run Swappiness is 0 (same behaviour as before but cache uses full memory straight away) Performance is terrible and unusable while running Ubuntu software Basic things like changing windows takes 2 minutes + Changing screens happens frame by frame over sometimes up to 5 minutes Cannot run an IDE and VM like I could with ease before So basically, any suggestions on how to take my performance back to how it was before while keeping my current setup? My suspicion is VMWare is the problem, but how do I see what is tied to the use of the cache? Surely there is a way to control this behaviour in software as polished as VMware? Thanks EDIT: Could also be important to note that the behaviour differs depending on whether VMware is open or closed. If VMware is open, then the ram will lock at like 50% and 50% cache and go into the complete lock up mentioned above. Contrastingly, if VMware is closed (after being open), then the RAM will continue to rise as it needs / cache will stay as the complete remaining memory and there is no noticeable performance degradation.

  • new project; entire node.js app

    - by Jared
    I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that? I was asked to re post this somewhere else as it was not up to the format for SO, OP from here http://stackoverflow.com/questions/12649469/new-project-need-some-start-up-advice-node-js-app#comment17062924_12649469

  • How do I stop ubuntu from detaching minimize/maximuze/close buttons?

    - by Shahbaz
    Some time ago I managed to get ubuntu to keep the window menubars in the menu rather than the bar above (I'm not sure if this part is unity or compiz, or what's the difference). That was by removing indicator-appmenu Anyway, so now everything is fine except one thing: If I have a window that is full screen, the minimize/maximize/close buttons are still grabbed by the bar on the top. Usually this doesn't cause a problem because the upper-left corner of the full screen window and the whole screen are not too far apart. However, one thing happens to me a lot, and that is I am working on something (programming), then I need to check some things from other places so I open some windows, see what I want and switch back to my work. Those windows however are temporary so at some point I want to close them. Now here's what happens: I have the focus on some window and I can't close the maximized window behind it unless I click on the window first, so that the buttons appear and then close it. I couldn't find anything on the internet about this. Is this something that's hardcoded in unity/compiz/whatever or is there actually a way to configure this?

  • Server-side Architecture for Online Game

    - by Draiken
    Hi, basically I have a game client that has communicate with a server for almost every action it takes, the game is in Java (using LWJGL) and right now I will start making the server. The base of the game is normally one client communicating with the server alone, but I will require later on for several clients to work together for some functionalities. I've already read how authentication server should be sepparated and I intend on doing it. The problem is I am completely inexperienced in this kind of server-side programming, all I've ever programmed were JSF web applications. I imagine I'll do socket connections for pretty much every game communication since HTML is very slow, but I still don't really know where to start on my server. I would appreciate reading material or guidelines on where to start, what architecture should the game server have and maybe some suggestions on frameworks that could help me getting the client-server communication. I've looked into JNAG but I have no experience with this kind of thing, so I can't really tell if it is a solid and good messaging layer. Any help is appreciated... Thanks !

  • How to change circular icon to indicate chosen session in unity-greeter?

    - by Chan-Ho Suh
    In Precise (12.04), when I login to lightdm, using the unity-greeter, there's a white circle by my name. For the standard DEs like Unity or XFCE, the circle has a representative icon (Ubuntu symbol or little mouse resp.). I have a session for Awesome window manager which was added when I installed Awesome, but it just shows a blank white circle. I'd like to know how to add an icon to it, or at least some indicator, as unity-greeter doesn't show you what session is set until you click on the circle. I found another question about changing the session names. The answer for it said to change the names in the desktop files in /usr/share/xsessions. Unfortunately, while there is an icon field in those desktop files, they are all blank (Caveat: I no longer have Unity installed, so maybe the Unity one would not be blank. But the Xubuntu desktop file has it blank even though the icon shows in unity-greeter). Update: Here's the png I use as a badge for Awesome. It's not great, but looks reasonably nice: []

  • LDAP for privilege control?

    - by neoice
    I've been wondering for a while if LDAP can be used to control user privileges. For example, if I have UNIX and web logins, is there an easy way to grant a user access to just or just UNIX (or even both?) My current attempt at solving this very problem was to create 'login' and 'nologin' groups, but this doesn't seem fine-grained enough to meet the ideas I have in my head. I'm also still in the situation where all UNIX users are web users, which isn't a problem so much as an indicator of the limitations. Does anyone have any input on this? Has this problem already been solved?
