  • shared transaction ID function among multiple threads

    - by poly
    I'm writing an application in C that requires multiple threads to request a unique transaction ID from a function as shown below; struct list{ int id; struct list *next }; function generate_id() { linked-list is built here to hold 10 millions } my concern is how to sync between two or more threads so that transaction id can be unique among them without using mutex, is this possible? Please share anything even if I need to change linked list to something else.

  • Running multiple versions of Firefox [migrated]

    - by redconservatory
    I've been reading this: http://support.mozilla.org/en-US/questions/797010#answer-193690 But it looks like it only applies to running multiple versions of Firefox when it's Firefox 4. I need to run Firefox but it seems like a lot of my clients are still running versions of Firefox 3 (is this an operating system issue? Doesn't Firefox auto-update?) so I need to run 3 plus the latest version to troubleshoot some css issues...

  • Map multiple functions over a single data item

    - by Linus Norton
    I'm in the process of learning Scala and I came across a scenario today where I need to map multiple functions over a single piece of data and wondered if there was a formal name for this. It sort of feels like the inverse of map. I'm not sure this is the correct way of expressing it, but this is what I did: dmap(x: Object, fns: List[Function]) = fns.map(_(x)) Is there a built in way to do something similar? Is there a formal name for this function?

  • Why would the boot screen be displayed on the external monitor?

    - by hegearon
    Why would the boot screen be displayed on the external monitor? This is not really a problem, I'd just like to know the reason behind this. If I boot without an external monitor both the BIOS settings and the boot screen are displayed on the built-in LCD monitor. However, when I boot with a monitor attached, the boot screen and the BIOS settings are displayed on the external monitor. There isn't any setting available regarding this in the BIOS setup (as opposed to my Thinkpad T42 where there is an option regarding this). System specification ASUS K53SV laptop DELL IN2030M monitor (connected via VGA) Windows 7 Enterprise SP1 64bit

  • Windows 7 pro remote desktop true multi monitor support patch or hack

    - by Ryan D
    After hours of research the closest i came to any patch that could fix this was a concurrent sessions patch which is not what i want. I have two machines both windows 7 professional. Its not an option to upgrade either to ultimate as the computer being remoted is in another state at our corp office. I need Dual monitor support and would have used the multimon i:1 edit thing however the other tower is not Win 7 ultimate. I have read over and over how it is not supported except with ultimate and enterprise and 2008 server. What have they put into windows 7 ultimate that is not in Win 7 pro and how can i get it or patch Win 7 pro to give it the same functionality. I would have paid for a software patch had i been able to find it anywhere. Summary: I am looking for the ability to remote to a Win 7 pro computer with another Win 7 computer while being able to use Dual monitors. Is there anyone that has the skill or balls to help with this? Most Respectfully Ryan

  • multiple monitor, ATI EyeFinity vs NVidia Mosaic on HDMI

    - by user1531897
    i have been googling much for answer but only someone with real experience can help here. my aim is to have 5 monitors connected to one computer in 2x2 full screen on all 4 monitors (video wall) with same resolution, 4xfullHD for example, plus one -5th monitor as controling. Ati have example picture of this configuration here. I have no gaming nor 3d needs here. Simple desktop applications plus video streams. So because graphic cards for this are expensive, i need to find out before buying pros and cons of 2 possible solutions (1) Ati Eyefinity capable card(s) ...and (2) Nvidia Quadro/NVS card(s) with mosaic and/or nvidia surround technology. For example i can find that current good cards for this can be: Ati's 7870 eyefinity6 card, link here pros: one card can handle all 5 displays, cons: active DP adapters needed (sometimes with aditional usb-powering complication) Nvidia Qudro NVS 450, link here Both cards have DisplayPorts as outputs (my targets are HDMI displays), but as far i saw information is that Eyefinity needs "active DP-DVI/hdmi adapters" for outputs and they are little expensive...? Does nvidia have this limitation (active adapters) ??? And final question, is Ati Eyefinity still better for this purpose than Nvidia-mosaic by someone's real experience there.

  • Monitor Exchange Email Address and run scripts

    - by WernerCD
    Okay... Not sure how "out there" this thought is... Right now to send a pager message (aka text message), a user logs into our AS400... logs into the program... enters user name and message and hit's F10 to send. With a little looking, it seems that you can run remote commands to the AS400 via FTP. So I'm working on building a script (batch or otherwise) that, given two parameters (user, message), will FTP into the AS400 and run a remote command: c:\>ftp server user: admin password: ***** ftp> quote rcmd SNDPGRMSG TOPGR(JDOE) MSG('This is a Test') ftp> quit So... what I want to do is setup an email account on our Exchange server Monitor the account for incoming mail upon receipt of incoming mail, parse it... say for example subject is defined as "Recipient" and email text is defined as "Pager message" run a batch that uses the above mentioned TOPGR and MSG as parameters... via FTP to the AS400 mark email as "read" The main thing I'm not sure about is monitoring an exchange account and running a script on incoming emails. I'm sure what I want to do is possible... but where would I start? EDIT: Clarification The main reasons for using this four part system are logging (messages sent via this are logged and reported by the AS400 program) and the existing scheduler for redirecting pages (For example, the weekly on-call person = TOPGR(oncall) gets updated by the AS400 program). I'm also trying to remove duplicate work. If I can get this setup working, I can redirect pages from OTHER systems into this one. I then don't have to update 2, soon to be 3, systems with current phone numbers, carriers, on-call schedules, etc. System #2 and #3 can just "email" [email protected].

  • Hyperic HQ- Monitor process statistics for 50+ processes on Linux machine

    - by Chris
    Is there an easy way to get metrics on all processes that start with the letters XYZ? I have about 80 processes that I have to monitor individually that all start with the prefix XYZ. I have created a query using the sigar shell: ps State.Name.sw=XYZ, which will give me a list of the processes that I want. What I need to do is define this list of processes through said query and collect and track statistics from the Process service: http://support.hyperic.com/display/hypcomm/Process+service What I need is 3 or 4 key statistics for each of the XYZ processes defined by my query to show up as graphs in the web front end. Note: Hyperic HQ server is installed on a windows machine and I'm monitoring a Linux box via an agent. Thanks, Chris Edit: Here is my try at a plugin that may give me what I want, but it's not being inventoried/detected by the Hyperic web UI. Simply pointing me to one of Hyperic's tutorials won't do. Thanks. <!DOCTYPE plugin [ <!ENTITY process-metrics SYSTEM "/pdk/plugins/process-metrics.xml">]> <plugin> <server name="ABCStats"> <config> <option name="process.query" description="Process Query" default="State.Name.sw=XYZ"/> </config> <metric name="Availability" alias="Availability" template="sigar:Type=ProcState,Arg=%process.query%:State" category="AVAILABILITY" indicator="true" units="percentage" collectionType="dynamic"/> &process-metrics; <plugin type="autoinventory"/> <plugin type="measurement" class="org.hyperic.hq.product.MeasurementPlugin"/> </server> </plugin>

  • Changing dual-monitor settings without closing the laptop lid on OS X

    - by hekevintran
    I have a Unibody MacBook hooked up to an external display. By default when I boot up, the system will go to dual-monitor mode. I want to use only the external display. The Apple supplied solution to this problem is to close the lid of the laptop which puts the machine into sleep mode and then move the mouse around to wake it up again. Because the machine is being woken up with the lid closed, when the displays are detected the system finds only the external. After the system is functional again, you can open the lid if you want and the laptop screen will be non-functional until you either tell the system to detect displays from the system preferences or you turn off the external display. Every time I want to use only the external display, I must reach my hand over to close the lid, wait for the machine to sleep, jigger the mouse, wait for the machine to wake up, and finally open the lid again because I don't want the machine to overheat. I feel that this is very stupid to have to do. Why is there no button or menu option that says "don't use this screen"? Is there any third-party software way to change the screen setup that does not involve physically closing the lid and playing a game of "are you sleeping" in order to switch such a simple software setting? We are in the 21st Century and honestly this is childish.

  • COMPAQ Tower No Signal to monitor

    - by Lancelot
    Hi there, I have had some troubles with this: I received a compaq tower: Compaq Presario SR1224NX Onboard VGA Windows XP SP2 from a friend. It was given to me on condition i give her the files back. My plan was to turn this into an Ubuntu Server. It booted up no problems even with the ubuntu live disc. After a normal shutdown(not unpluggin the power cord and not doing a hard shutdown with the power button), it would not restart even after SEVERAL attempts. I realized the light next to the power supply would flash very rapidly. I researched and found out it was one of two things: a dead power supply or the cables to the motherboard and to the disks etc. Thus i checked to ensure the cables were fine(and they were). I purchased a Power Supply (this one has 400 watts, the initial had 250) and installed it. The tower now boots. It booted into the live disk and everything. After a normal shutdown, it now restarts but is not sending signal to my monitor. I have tried several monitors in which i assure work perfectly but not with this tower(i recall it did show display after replacing the power supply). The monitors are ACER. This is different than most "no Signal" problems since i am not using an external Video Card, this is onboard VGA. Thanks!

  • Multi monitor setup with a tv as well?

    - by jasondavis
    I have always had a dual monitor setup for my pc's for years now. I am now in the market to build a new PC and get some new stuff. I need some help or advice on how to run 3 monitors WITH a 4th display which will be a lcd/plasma tv. So I am thinking I can get 2 video cards and that will give me all the hookups to run 3 monitors instead of 2. I will mount all 3 monitors in a row side by side and above them on the wall I would like to mount a larger 30-40+ inch lcd or plasma tv. I would then like to hook up my atelite/cable to this tv just as I would normally hook up a tv but I would like to also be able to have an option to view my PC o this tv as well. I know that is possible but would it be possible to view my PC on that tv and also still view my 3 other monitors and have the TV be a 4th display, where I could dock a different app/window in windows in all 4 displays (3 monitors + tv) ?? Please tell me any tips/advice on how to do this including what cables/software if any/converters/ you name it. Thanks for any help

  • In solaris, how monitor & auto-respond to critical events

    - by mamcx
    I have a website that randomly fail. Is running in open solaris on joyent. I have a monitoring service that alert me when the site is down, but, I want a way to put a "insider" tool that tell me why that happened. Is because the cpu is too high? Not memory? Which process fail? Is possible to have a backtrace of that? Everything is running on the Solaris Service Management Facility. The webserver is cherokee, the database is mysql and the language is python/django. I want the most simple setup to monitor that & auto-respond , ie: restart the webserver or the django process in case of failure. I prefer a low-overhead tool. I don't need the fancy monitoring that some tools have, no ned graphs or sms alert. Only know what fail, restart it if possible (maybe up to n times), and have a log somewhere when I will check it.

  • Configure a Windows PC as network appliance w/o monitor, keyboard and mouse

    - by Joshua Lim
    I intend to use a small form factor PC with Windows 7 Professional installed as a network appliance attached directly to my customer's LAN without connecting a monitor, keyboard or mouse. How should I configure the networking for my PC so that I can access it via say my laptop? I figure that I can do it 2 ways. Attach my laptop to the PC using a crossover cable? Connect via RDP and configure networking. Configure an IP address on the PC before I deliver it to the customer place. At the customer's place, attach the PC to LAN and connect to the IP address which I previously configured from my laptop or from one of the customer's workstations. I know the first way is doable, but is the second way possible? I'm sorry if this question sounds ridiculous - I am Delphi programmer but a novice on networking. Finally, if possible, I hope to make the configuration process web based as I wouldn't like to reveal the fact that I am using Win7 Pro for the network appliance!

  • How can I monitor VNC via Nagios?

    - by atroon
    I have a number of remote sites which have VNC running on a few computers for support purposes. They are (obviously) only available on our internal network. I am using Nagios to keep track of all the systems in the network and I want to have it check to make sure the VNC server is running on the appropriate hosts. There is a 'check_vnc' plugin available here but it relies on VNC Snapshot which I don't want to use. Certainly I could use it, but it adds more complexity and dependency, which I want to avoid. It seems simpler to just use check_tcp to make sure I get the proper response to a connection request for VNC, e.g. port 5900, send a connect string, get back framebuffer info. My real question, I suppose, is this: What is the 'proper' generic connect string for VNC (I use both UltraVNC and RealVNC) and what is the expected response? If it's really easier to use the VNC Snapshot and check_vnc, let me know. I just can't imagine that a string of text isn't easier, faster, and less bandwidth intensive to monitor.
