  • More than one JPanel in a Frame / having a brackground Image and another Layer with Components on the top

    - by user1905203
    I've got a JFrame with a JPanel in which there is a JLabel with an ImageIcon(). Everything's working perfectly, problem is i now want to add another JPanel with all the other stuff like buttons and so on to the JFrame. But it still shows the background Image on top and nothing with the second JPanel. Can someone help me? Here is an extract of my code: JFrame window = new JFrame("Http Download"); /* * Background Section */ JPanel panel1 = new JPanel(); JLabel lbl1 = new JLabel(); /* * Component Section */ JPanel panel2 = new JPanel(); JLabel lbl2 = new JLabel(); /* * Dimension Section */ Dimension windowSize = new Dimension(800, 600); Dimension screen = Toolkit.getDefaultToolkit().getScreenSize(); public HTTPDownloadGUI() { window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); panel1.setLayout(null); panel1.setSize(windowSize); panel1.setOpaque(false); panel2.setLayout(null); panel2.setSize(windowSize); panel2.setOpaque(false); lbl1.setSize(windowSize); lbl1.setLocation(0, 0); lbl1.setIcon(new ImageIcon(getClass().getResource("bg1.png"))); panel1.add(lbl1); lbl2.setBounds(0, 0, 100, 100); //lbl2.setIcon(new ImageIcon(getClass().getResource("bg2.png"))); lbl2.setBackground(Color.GREEN); panel2.add(lbl2); panel1.add(panel2); window.add(panel1); int X = (screen.width / 2) - (windowSize.width / 2); int Y = (screen.height / 2) - (windowSize.height / 2); window.setBounds(X,Y , windowSize.width, windowSize.height); window.setVisible(true); }

  • Processing JSON data with jQuery - strange results needing alert()

    - by James
    I have this code below. I randomly ran across that it will work if I have that alert message exactly where it is. If I take it out or move it to any other spot the tabs will not appear. What exactly is that alert doing that allows the code to work and how can I make it work without the alert? If I move the each loop into the success section it does not work even with the alert. $.ajax({ type: "GET", url: "../ajax.php", data: "action=tabs", dataType: "json", success: function(data){ Projects = data; } }); alert("yes"); $.each(Projects, function(i){ /* Sequentially creating the tabs and assigning a color from the array: */ var tmp = $('<li><a href="#" class="tab green">'+Projects[i].name+'<span class="left" /><span class="right" /></a></li>'); /* Setting the page data for each hyperlink: */ tmp.find('a').data('page','../ajax.php?action=lists&projectID='+Projects[i].project_id); /* Adding the tab to the UL container: */ $('ul.tabContainer').append(tmp); }); The ajax code is retuning json with this code $query = mysql_query("SELECT * FROM `projects` ORDER BY `position` ASC"); $projects = array(); // Filling the $projects array with new project objects: while($row = mysql_fetch_assoc($query)){ $projects[] = $row; } echo json_encode($projects); The returning data is very small and very fast so I don't think that is the problem.

  • Issue in alternate Row color using each() method of JQuery

    - by user1323981
    I have a table as under <table > <tr> <th scope="col">EmpId</th><th scope="col">EmpName</th> </tr> <tr> <td>1</td><td>ABC</td> </tr> <tr> <td>2</td><td>DEF</td> </tr> </table> I want to set the alternate row color of only the "td" elements of the table and not "th" by using only each() function. I have tried with <style type="text/css"> tr.even { background-color: green; } tr.odd { background-color: yellow; } </style> $(document).ready(function () { $('table > tbody').each(function () { $('tr:odd', this).addClass('odd').removeClass('even'); $('tr:even', this).addClass('even').removeClass('odd'); }); }); Though this works but it accepts also "th" element. How to avoid that? Please help Thanks

  • multiple touches: touchend event fired only when a touchmove occurs

    - by dridri
    I would like to add some multitouch features to my javascript application when it is accessed from an ios device (and maybe android later). I want to provide a shiftkey-like functionality: the user may hold a button on the screen with one finger, and while this button is pressed, the behavior for a tap action on the rest of the screen is slightly different from the classic tap. The problem i'm running into is that i do not receive any touchend event for the tapping finger unless a touchmove is fired for the first finger holding the shiftkey button. Because the screen is very sensitive, touchmove events gets easily fired and in most cases everything works fine. But when the user's finger is a bit too still, the tapping is not detected until the user moves his finger a bit. This induces a variable 'delay' between the tapping and the action that occurs on the screen (the delay may vary and last a few seconds if the user is very calm). My guess is that this delay will cause the user to tap again and thus fire the action a second time, which is something that i don't want ! You can test it here with your ipad/iphone : http://jsfiddle.net/jdeXH/8/ Try to make the body remain green for a few seconds by holding your finger very still on the cyan div while tapping on the red div. Is this behavior to be expected ? Is there some known workaround for the problem ? I would have expected the touchend event to be fired right away when the finger is removed from the screen. i tested this with iOS 5.1.1 (ipad1 and iphone4s) edit: found a similar question Multitouch touchEvents not triggered as they should on Safari Mobile

  • NHibernate mapping with optimistic-lock="version" and dynamic-update="true" is generating invalid up

    - by SteveBering
    I have an entity "Group" with an assigned ID which is added to an aggregate in order to persist it. This causes an issue because NHibernate can't tell if it is new or existing. To remedy this issue, I changed the mapping to make the Group entity use optimistic locking on a sql timestamp version column. This caused a new issue. Group has a bag of sub objects. So when NHibernate flushes a new group to the database, it first creates the Group record in the Groups table, then inserts each of the sub objects, then does an update of the Group records to update the timestamp value. However, the sql that is generated to complete the update is invalid when the mapping is both dynamic-update="true" and optimistic-lock="version". Here is the mapping: <class xmlns="urn:nhibernate-mapping-2.2" dynamic-update="true" mutable="true" optimistic-lock="version" name="Group" table="Groups"> <id name="GroupNumber" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupNumber" length="5" /> <generator class="assigned" /> </id> <version generated="always" name="Timestamp" type="BinaryBlob" unsaved-value="null"> <column name="TS" not-null="false" sql-type="timestamp" /> </version> <property name="UID" update="false" type="System.Guid, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupUID" unique="true" /> </property> <property name="Description" type="AnsiString"> <column name="GroupDescription" length="25" not-null="true" /> </property> <bag access="field.camelcase-underscore" cascade="all" inverse="true" lazy="true" name="Assignments" mutable="true" order-by="GroupAssignAssignment"> <key foreign-key="fk_Group_Assignments"> <column name="GroupNumber" /> </key> <one-to-many class="Assignment" /> </bag> <many-to-one class="Aggregate" name="Aggregate"> <column name="GroupParentID" not-null="true" /> </many-to-one> </class> </hibernate-mapping> When the mapping includes both the dynamic update and the optimistic lock, the sql generated is: UPDATE groups SET WHERE GroupNumber = 11111 AND TS=0x00000007877 This is obviously invalid as there are no SET statements. If I remove the dynamic update part, everything gets updated during this update statement instead. This makes the statement valid, but rather unnecessary. Has anyone seen this issue before? Am I missing something? Thanks, Steve

  • "No message serializer has been configured" error when starting NServiceBus endpoint

    - by SteveBering
    My GenericHost hosted service is failing to start with the following message: 2010-05-07 09:13:47,406 [1] FATAL NServiceBus.Host.Internal.GenericHost [(null)] <(null) - System.InvalidOperationException: No message serializer has been con figured. at NServiceBus.Unicast.Transport.Msmq.MsmqTransport.CheckConfiguration() in d:\BuildAgent-02\work\672d81652eaca4e1\src\impl\unicast\NServiceBus.Unicast.Msmq\ MsmqTransport.cs:line 241 at NServiceBus.Unicast.Transport.Msmq.MsmqTransport.Start() in d:\BuildAgent-02\work\672d81652eaca4e1\src\impl\unicast\NServiceBus.Unicast.Msmq\MsmqTransport .cs:line 211 at NServiceBus.Unicast.UnicastBus.NServiceBus.IStartableBus.Start(Action startupAction) in d:\BuildAgent-02\work\672d81652eaca4e1\src\unicast\NServiceBus.Uni cast\UnicastBus.cs:line 694 at NServiceBus.Unicast.UnicastBus.NServiceBus.IStartableBus.Start() in d:\BuildAgent-02\work\672d81652eaca4e1\src\unicast\NServiceBus.Unicast\UnicastBus.cs:l ine 665 at NServiceBus.Host.Internal.GenericHost.Start() in d:\BuildAgent-02\work\672d81652eaca4e1\src\host\NServiceBus.Host\Internal\GenericHost.cs:line 77 My endpoint configuration looks like: public class ServiceEndpointConfiguration : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization { public void Init() { // build out persistence infrastructure var sessionFactory = Bootstrapper.InitializePersistence(); // configure NServiceBus infrastructure var container = Bootstrapper.BuildDependencies(sessionFactory); // set up logging log4net.Config.XmlConfigurator.Configure(); Configure.With() .Log4Net() .UnityBuilder(container) .XmlSerializer(); } } And my app.config looks like: <configSections> <section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core" /> <section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core" /> <section name="Logging" type="NServiceBus.Config.Logging, NServiceBus.Core" /> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false" /> </configSections> <Logging Threshold="DEBUG" /> <MsmqTransportConfig InputQueue="NServiceBus.ServiceInput" ErrorQueue="NServiceBus.Errors" NumberOfWorkerThreads="1" MaxRetries="2" /> <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress="" ForwardReceivedMessagesTo="NServiceBus.Auditing"> <MessageEndpointMappings> <!-- publishers don't need to set this for their own message types --> </MessageEndpointMappings> </UnicastBusConfig> <connectionStrings> <add name="Db" connectionString="Data Source=..." providerName="System.Data.SqlClient" /> </connectionStrings> <log4net debug="true"> <root> <level value="INFO"/> </root> <logger name="NHibernate"> <level value="ERROR" /> </logger> </log4net> This has worked in the past, but seems to be failing when the generic host starts. My endpoint configuration is below, along with the app.config for the service. What is strange is that in my endpoint configuration, I am specifying to use the XmlSerializer for message serialization. I don't see any other errors in the console output preceding the error message. What am I missing? Thanks, Steve

  • iSCSI timeouts under high load

    - by Antonio
    I have two servers connected via Gigabit Ethernet. One is iSCSI target, the second one is initiator. When I run mkfs.ext4 at initiator, after a while disk IO slows down critically. In the target host I can see the following in syslog: Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668c 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668c 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668d 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668d 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668e 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668e 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 1196696 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 1196696 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119669e 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119669e 6 Sep 14 09:40:04 sh11 tgtd: abort_task_set(1139) found 119669f 0 Sep 14 09:40:04 sh11 tgtd: abort_cmd(1115) found 119669f 6 And load average grows to 12 or even more: # uptime 12:37:00 up 23 days, 13:25, 1 user, load average: 12.00, 7.00, 4.00 CentOS 6.3 tgtd 1.0.24 Intel Pentium 4 2.4GHz 1Gb RAM 2Tb WD Cavlar Green SATA 2.0 #lspci 00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 02) 00:01.0 PCI bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE Host-to-AGP Bridge (rev 02) 00:1d.0 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 82) 00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC Interface Bridge (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 02) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV200 QW [Radeon 7500] 02:01.0 Ethernet controller: D-Link System Inc DGE-530T Gigabit Ethernet Adapter (rev 11) (rev 11) 02:02.0 RAID bus controller: VIA Technologies, Inc.

  • IRP_MJ_WRITE latency up to 15 seconds

    - by racitup
    We have written an application that performs small (22kB) writes to multiple files at once (one thread performing asynchronous queued writes to multiple locations on behalf of other threads) on the same local volume (RAID1). 99.9% of the writes are low-latency but occasionally (maybe every minute or two) we get one or two huge latency writes (I have seen 10 seconds and above) without any real explanation. Platform: Win2003 Server with NTFS. Monitoring: Sysinternals Process Monitor (see link below) and our own application logging. We have tried multiple things to try and solve this that have been gleaned from a few websites, e.g.: Making the first part of file names unique to aid 8.3 name generation Writing files to multiple directories Changing Intel Disk Write Caching Windows File/Printer Sharing Minimize memory used Balance Maximize data throughput for file sharing Maximize data throughput for network applications System-Advanced-Performance-Advanced NtfsDisableLastAccessUpdate - use fsutil behavior set disablelastaccess 1 disable 8.3 name generation - use "fsutil behavior set disable8dot3 1" + restart Enable a large size file system cache Disable paging of the kernel code IO Page Lock Limit Turn Off (or On) the Indexing Service But nothing seems to make much difference. There's a whole host of things we haven't tried yet but we wondered if anyone had come across the same problem, a reason and a solution (programmatic or not)? We can reproduce the problem using IOMeter and a simple setup: Start IOMeter and remove all but the first worker thread in 'Topology' using the disconnect button. Select the Worker thread and put a cross in the box next to the disk you want to use in the Disk Targets tab and put '2000000' in Maximum Disk Size (NOTE: must have at least 1GB free space; sector size is 512 bytes) Next create a new access specification and add it to the worker thread: Transfer Request Size = 22kB 100% Sequential Percent of Access Spec = 100% Percent Read/Write = 100% Write Change Results Display Update Frequency to 5 seconds, Test Setup Run Time to 20 seconds and both 'Number of Workers to Spawn Automatically' settings to zero. Select the Worker Thread in the Topology panel and hit the Duplicate Worker button 59 times to create 60 threads with identical settings. Hit the 'Go' button (green flag) and monitor the Results tab. The 'Maximum I/O Response Time (ms)' always hits at least 3500 on our machine. Our machine isn't exactly slow (Xeon 8 core rack server with 4GB and onboard RAID). I'd be interested to see what other people get. We have a feeling it might be something to do with the NTFS filesystem (ours is currently 75% full of fragmented files) and we are going to try a few things around this principle. But it is also related to disk performance since we don't see it on a RAMDisk and it's not as severe on a RAID10 array. Any help is much appreciated.

  • Blank Screen After Login on Windows 7

    - by Leigh Riffel
    When unlocking a Windows 7 computer the screen briefly (less than a second) goes blank before showing the screen. Abound once a month (but sometimes within a few days) when I unlock my computer the screen doesn't come back from this brief blackout and stays black. Sometimes after five minutes or so the display will come back. Other times it has been blank for over 20 minutes, so I give up and restart the computer. It seems to happen more often when the computer has been locked for a longer period of time - I lock my computer several times a day, but the problem most happens when I come in at the start of the day. I have updated my video card and monitor drivers. I have two monitors driven by the same graphics card. The computer is a Dell Optiplex 740. When the problem occurs both monitors have a green light on to indicate that they are receiving signal. I've tried unplugging the monitors from the video card and turning the monitors on and off. The screen saver is set to one that is not blank screen. The Windows power settings are set to never turn off the display. When the problem occurs there is no significant disk activity occurring. When the problem occurs I can connect over the network to the hard drive on my computer. When the problem occurs I can't connect over the network with a VNC connection. The VNC client doesn't give an error, but also won't show the screen. The task actually seems to hang as I can see the task, but there is no window for it. This problem occurred when I was running a pre-release version of Windows 7. The hard drive was formatted for release version and the problem still occurs. I've been stopping some of my always running programs to see if one of them may be the culprit, but given the span between failures that will take some time to find the problem if it will even help at all. Some programs I have always running include IE, Firefox, Outlook, Evernote, Kana Reminder, Ditto, Macro Express, Timesnapper, and DisplayFusion. Any ideas appreciated.

  • HT Link Sync Error after Ubuntu 10.04 LTS Installation

    - by marklab
    Update 1 I just assembled an exact replica of this server, and successfully installed Ubuntu 10.04 LTS in a RAID10 configuration. The success was confirmed by a login to the initial account. There must be a hardware component that is faulty. Since the error mentions HT, which I believe to be Hyper Threading, I will start with the CPUs. Please indicate if this error is more strongly associated with any other piece of hardware. Or make a recommendation of another approach that would be good for this issue. Issue I was attempting to install Ubuntu 10.04 LTS on this system with the board RAID10 configured. However, the installation failed at the partitioning stage by rebooting the system. Upon reboot, there is an error report after POST listing the following: Node0: NB WatchDog Timer Error Node1: HT Link Sync Error Node2: HT Link Sync Error ... Node7: HT Link Sync Error Press F1 to continue/resume. After pressing F1 the system will boot from the Ubuntu 10.04 LTS installation disc. However, it will fail at the same stage, and go through the same process from there. Hardware CPU: AMD OPTERON X12 6172 G34 2.1G 18MB Motherboard: Supermicro H8QG6-F HDD: WD Caviar Green 2TB 5.4K RPM Troubleshooting I disabled RAID10 on the system, and installed the Ubuntu on a single drive. It installed successfully. I then went back to a RAID10 setup and attempted to install on the system again, and was able to make it through the partitioning stage. However, upon reboot, the system reported: Error: file not found, and then booted me into the Grub Rescue console. I feel I have aggravated the problem at this point because when I attempted to install from the boot disc again, the system reboots upon hitting enter to even start the installation process. It does the same thing when trying to boot from an Ubuntu 11 disc. I have not been able to find any information on this HT Link Sync Error, which I feel may have started the problems I am experiencing now with the installation of the OS. I am also aware that Ubuntu is said not to be supported by the motherboard according to Supermicro's site. However, since I was able to install it successfully on a single drive, I do not believe it is incompatible. I would like to know a reason for why it's failing to install on/off.

  • HP DAT72x6 autoloader

    - by ericmayo
    Hoping someone here has seen this similar issue and can offer soem advise... I have an HP DAT72x6 auto loader tape backup unit. The external kind, here is a link to an owner's manual I found of it. http://www.dectrader.com/docs/set2/emr_na-c00070400-1.pdf I purchased the unit used about 6 months ago. The unit stopped working after 3-4 back-ups, it's used one day a month to do a monthly backup of another system. Suffice it to say the unit gets very little usage. There is an amber light on the front of the unit called the OAR (Operator Attention Required). The manual states to call for service when this light comes on and stays on. I've tried a few things to resolve but none are working. I've tried power cycling, re-securing the SCSI cables at both ends. Unit was used so I didn't pay much ($500) and so I don't want to spend a lot to have it fixed; might as well buy something new one if fixing this is going to cost more than $100-$150 bucks. I'm curious to see if anyone here has been around these devices or possibly is an HP repair person that can give me some things to try to resolve. The manual states that a solid amber OAR light indicates a hardware failure. When I power cycle the unit I see one of two scenarios so far. The unit powers up, shows self test in the LCD, then LCD changes to show all possible images and the OAR light comes on. The unit powers up, LCD is completely blank, the green lights go through some sort of process of going on and off and later the amber OAR light comes on and stays on. If it's a simple misalignment issue, I may be able to fix myself but not knowing what could cause the OAR light to come on gives me no where to even start. Google around gave no help either. I hoping someone here has experience with this and can help or point me in the right direction. Also, I don't have the HP Diagnostic tools mentioned in many manuals. The unit is connected to a Linux box. The 3-4 backups I've done with it so far have had no issues. We run amanda backup. Before this incident the unit was backing up and reading tapes fine. Thanks for any help or suggestions.

  • Code Complete 2ed, composition and delegation.

    - by Arlukin
    Hi there. After a couple of weeks reading on this forum I thought it was time for me to do my first post. I'm currently rereading Code Complete. I think it's 15 years since the last time, and I find that I still can't write code ;-) Anyway on page 138 in Code Complete you find this coding horror example. (I have removed some of the code) class Emplyee { public: FullName GetName() const; Address GetAddress() const; PhoneNumber GetWorkPhone() const; ... bool IsZipCodeValid( Address address); ... private: ... } What Steve thinks is bad is that the functions are loosely related. Or has he writes "There's no logical connection between employees and routines that check ZIP codes, phone numbers or job classifications" Ok I totally agree with him. Maybe something like the below example is better. class ZipCode { public: bool IsValid() const; ... } class Address { public: ZipCode GetZipCode() const; ... } class Employee { public: Address GetAddress() const; ... } When checking if the zip is valid you would need to do something like this. employee.GetAddress().GetZipCode().IsValid(); And that is not good regarding to the Law of Demeter ([http://en.wikipedia.org/wiki/Law_of_Demeter][1]). So if you like to remove two of the three dots, you need to use delegation and a couple of wrapper functions like this. class ZipCode { public: bool IsValid(); } class Address { public: ZipCode GetZipCode() const; bool IsZipCodeValid() {return GetZipCode()->IsValid()); } class Employee { public: FullName GetName() const; Address GetAddress() const; bool IsZipCodeValid() {return GetAddress()->IsZipCodeValid()); PhoneNumber GetWorkPhone() const; } employee.IsZipCodeValid(); But then again you have routines that has no logical connection. I personally think that all three examples in this post are bad. Is it some other way that I haven't thougt about? //Daniel

  • Microphones not working on Apple macbook Air 1,1 (Early 2008) under Linux

    - by jj_p
    I'm running Linux on an mba. I can't make the microphones (neither external nor internal) work. I test using alsamixer and arecord -d 5 test-mic.waw together with aplay test-mic.waw It seems there is a problem with kernel trying to decipher Apple (intentionally) corrupted 'bios', in particular the mic pins are wrongly assigned. As far as we are concerned here, is there any difference between using EFI and BIOS-compatibility mode? (see https://wiki.archlinux.org/index.php/MacBook where they claim to have everything working out of the box on mba1,1) A nice proposal would be to compile the latest Linux kernel and run hda-jack-retask to find the right configuration (in the case of Realtek codec, the missing things I'm supposed to check are either some vendor-specific COEF verbs, EAPD or GPIO setup.), and then come up with a kernel patch to address the issue. Since I'm not that familiar with this last part of the story, can anyone help me through this process? Some useful data: The output from alsa script run as root http://www.alsa-project.org/db/?f=adae8ebee1007043fe83414ac4972319e02255fa The command hda-jack-sense-test -a (with external mic in) Pin 0x14 (Internal Speaker): present = No Pin 0x15 (Green HP Out): present = Yes Pin 0x16 (Not connected): present = No Pin 0x17 (Not connected): present = No Pin 0x18 (Not connected): present = No Pin 0x19 (Not connected): present = No Pin 0x1a (Not connected): present = No Pin 0x1b (Not connected): present = No Pin 0x1c (Not connected): present = No Pin 0x1d (Not connected): present = No Pin 0x1e (Not connected): present = No Pin 0x1f (Not connected): present = No Most likely the chip is Realtek ALC885 (compare also ALC889A) http://guide-images.ifixit.net/igi/bBTSqaeK5JpQ1AWe.large , although at the moment alsa reads it as ALC889A Takashi Iwai's tutorial https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt Some people researched the original files from a running OS X installation on this same model (I think the relevant files are AppleHDA.kext/Contents/MacOS/AppleHDA AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.p????list AppleHDA.kext/Contents/Resources/layout12.xml.zlib AppleHDA.kext/Contents/Resources/Platforms.xml.zlib) http://www.insanelymac.com/forum/topic/220090-alc889a-pin-configuration/#entry1554954 Datasheet http://www.realtek.info/pdf/ALC885_1-1.pdf (from the same Realtek, one can also try to download Linux driver, but this is just taken from ALSA project, as stated in the readme file.)

  • Has the hardware in my modem gone bad?

    - by Tyler Scott
    I contacted CenturyLink about my modem recently and received useless and unrelated information. The problem seems to be that the modem will no longer save settings, the web interface is unusable except in internet explorer for some reason, and the modem keeps resetting. CenturyLink claimed it had to do with signal strength but I checked and it is currently between good and outstanding according to this. All of the lights remain green even when it starts acting up and I lose internet and shortly before it crashes and reboots. Does anyone have any idea what is going on or what I can do to fix it? (Asking CenturyLink again is obviously not going to help.) Update 1: Accessing the syslog from the web interface causes a crash. After it reboots, the log looks like as follows: 01/01/1970 12:01:29 AM Ethernet Ethernet client connected ,ip(192.168.0.2), mac(1c:6f:65:4c:6d:3b) 01/01/1970 12:01:38 AM Wireless 802.11 client connected ,ip(192.168.0.18), mac(d0:df:c7:c2:73:ca) 01/01/1970 12:01:41 AM System Event Line 0: VDSL2 link up, Bearer 0, us=20128, ds=40127 01/01/1970 12:01:43 AM dhcp6s[2028] dhcp6_ctl_authinit: failed to open /etc/dhcp6sctlkey: No such file or directory 01/01/1970 12:01:50 AM dhcp6s[2469] dhcp6_ctl_authinit: failed to open /etc/dhcp6sctlkey: No such file or directory 01/01/1970 12:01:52 AM radvd[2306] poll error: Interrupted system call 01/01/1970 12:01:56 AM PPP Link PPP server detected. 01/01/1970 12:01:56 AM PPP Link PPP session established. 01/01/1970 12:01:56 AM PPP Link PPP LCP UP. 01/01/1970 12:01:56 AM System Event Received valid IP address from server.

  • Is the Scala 2.8 collections library a case of "the longest suicide note in history" ?

    - by oxbow_lakes
    First note the inflammatory subject title is a quotation made about the manifesto of a UK political party in the early 1980s. This question is subjective but it is a genuine question, I've made it CW and I'd like some opinions on the matter. Despite whatever my wife and coworkers keep telling me, I don't think I'm an idiot: I have a good degree in mathematics from the University of Oxford and I've been programming commercially for almost 12 years and in Scala for about a year (also commercially). I have just started to look at the Scala collections library re-implementation which is coming in the imminent 2.8 release. Those familiar with the library from 2.7 will notice that the library, from a usage perspective, has changed little. For example... > List("Paris", "London").map(_.length) res0: List[Int] List(5, 6) ...would work in either versions. The library is eminently useable: in fact it's fantastic. However, those previously unfamiliar with Scala and poking around to get a feel for the language now have to make sense of method signatures like: def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That For such simple functionality, this is a daunting signature and one which I find myself struggling to understand. Not that I think Scala was ever likely to be the next Java (or /C/C++/C#) - I don't believe its creators were aiming it at that market - but I think it is/was certainly feasible for Scala to become the next Ruby or Python (i.e. to gain a significant commercial user-base) Is this going to put people off coming to Scala? Is this going to give Scala a bad name in the commercial world as an academic plaything that only dedicated PhD students can understand? Are CTOs and heads of software going to get scared off? Was the library re-design a sensible idea? If you're using Scala commercially, are you worried about this? Are you planning to adopt 2.8 immediately or wait to see what happens? Steve Yegge once attacked Scala (mistakenly in my opinion) for what he saw as its overcomplicated type-system. I worry that someone is going to have a field day spreading fud with this API (similarly to how Josh Bloch scared the JCP out of adding closures to Java). Note - I should be clear that, whilst I believe that Josh Bloch was influential in the rejection of the BGGA closures proposal, I don't ascribe this to anything other than his honestly-held beliefs that the proposal represented a mistake.

  • Copy android.R.layout to my project

    - by eric
    Good advice from CommonWare and Steve H but it's not as easy to me as I first thought. Based on their advice I'm trying to copy android.R.layout to my project to ensure consistency. How do you do this? I looked in Eclipse's Package Explorer and under Android 1.5android.jarandroidR.classRlayout and find R$layout.class. Do I copy the code out of there into my own class? From my very limited knowledge of Java, the following code doesn't make much sense: public static final class android.R$layout { // Field descriptor #8 I public static final int activity_list_item = 17367040; // Field descriptor #8 I public static final int browser_link_context_header = 17367054; // Field descriptor #8 I public static final int expandable_list_content = 17367041; // Field descriptor #8 I public static final int preference_category = 17367042; // Field descriptor #8 I public static final int select_dialog_item = 17367057; // Field descriptor #8 I public static final int select_dialog_multichoice = 17367059; // Field descriptor #8 I public static final int select_dialog_singlechoice = 17367058; // Field descriptor #8 I public static final int simple_dropdown_item_1line = 17367050; // Field descriptor #8 I public static final int simple_expandable_list_item_1 = 17367046; // Field descriptor #8 I public static final int simple_expandable_list_item_2 = 17367047; // Field descriptor #8 I public static final int simple_gallery_item = 17367051; // Field descriptor #8 I public static final int simple_list_item_1 = 17367043; // Field descriptor #8 I public static final int simple_list_item_2 = 17367044; // Field descriptor #8 I public static final int simple_list_item_checked = 17367045; // Field descriptor #8 I public static final int simple_list_item_multiple_choice = 17367056; // Field descriptor #8 I public static final int simple_list_item_single_choice = 17367055; // Field descriptor #8 I public static final int simple_spinner_dropdown_item = 17367049; // Field descriptor #8 I public static final int simple_spinner_item = 17367048; // Field descriptor #8 I public static final int test_list_item = 17367052; // Field descriptor #8 I public static final int two_line_list_item = 17367053; // Method descriptor #50 ()V // Stack: 3, Locals: 1 public R$layout(); 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 899] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: android.R.layout Inner classes: [inner class info: #5 android/R$layout, outer class info: #64 android/R inner name: #55 layout, accessflags: 25 public static final] }

  • Looking for Fiddler2 help. connection to gateway refused? Just got rid of a virus

    - by John Mackey
    I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed.Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

  • Why do some games randomly turn my screen a random solid color?

    - by Emlena.PhD
    When playing some games my computer will randomly have an error that I cannot fix without turning it off and back on again. The screen changes to one solid color, which varies (off the top of my head I can remember seeing solid green, magenta, etc..) and the sound blares a single tone. The sound sometimes briefly restores and I can still hear the game sounds and even hear and still be heard by people in my Mumble channel, but the screen doesn't right itself so I'm still blind. What's more is this happens in some games but not in others. While the game is actually running, not while I'm still in the menu. However, it does happen if I'm afk or idle but the game world is still rendering. Games where the error occurs: League of Legends World of Warcraft Trine The Sims 2 Dungeon Defenders Safe games: games where it has never occurred: Tribes: Ascend Star Wars: the Old Republic Battlefield 3 So relatively older games cause the problem while newer games do not? I cannot predict when it will happen, it just seems random. However, if it happens and I try playing the same game further after restart it does appear to occur more frequently after the first time. But if I switch to a safe game it doesn't continue happening. Both of my RAM sticks appear fine, flipped position or either one on their own and games still run, computer still boots. I would think over-heating, but then why not all games? ALso, sometimes it happens immediately after I start playing, within seconds of the 3D world booting up. I'm looking to upgrade very soon so I want to figure out what component or software is fubar and replace/repair it. Any suggestions or recommendations of tools would be helpful. Below is some system information. Dxdiag does not detect any problems. Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120305-1505) System Manufacturer: Gigabyte Technology Co., Ltd.

  • Using jQuery or javascript to render json into multi-column table

    - by Scott Yu - UX designer
    I am trying to render a JSON into a HTML table. But the difficulty is making it so it loops through JSON and renders multiple columns if necessary. For the example below, what I want is this: Result wanted Result Wanted <table> <tr><th>AppName</th><td>App 1</td><td>App 2</td></tr> <tr><th>Last Modified</th><td>10/1/2012</td><td></td></tr> <tr><th>App Logo</th><td>10/1/2012</td><td></td></tr> blahblah </table> <table> <tr><th>AppName</th><td>App 1</td></tr> blahblah </table> JSON Example "Records": [ { "AppName": "App 1", "LastModified": "10/1/2012, 9:30AM", "ShipTo_Name": "Dan North", "ShipTo_Address": "Dan North", "ShipTo_Terms": "Dan North", "ShipTo_DueDate": "Dan North", "Items 1": [ { "Item_Name": "Repairs", "Item_Description": "Repair Work" } ] }, { "AppName": "App 2", "AppLogo": "http://www.google.com/logo.png", "LastModified": "10/1/2012, 9:30AM", "BillTo_Name": "Steve North", "Items 1": [ { "Item_Name": "Repairs", "Item_Description": "Repair Work" } ] } ], "Records": [ { "AppName": "App 1", "LastModified": "10/1/2012, 9:30AM", "ShipTo_Name": "222", "ShipTo_Address": "333 ", "ShipTo_Terms": "444", "ShipTo_DueDate": "5555", "Items 1": [ { "Item_Name": "Repairs", "Item_Description": "Repair Work" } ] } ], Code I am using now function CreateComparisonTable (arr,level,k) { var dumped_text = ""; if(!level) level = 0; //The padding given at the beginning of the line. var level_padding = ""; for(var j=0;j<level+1;j++) level_padding = "--"; if(typeof(arr) == 'object') { //Array/Hashes/Objects for (var item in arr) { var value = arr[item]; if (typeof(value) == 'object') { //If it is an array, if(item !=0) { dumped_text += '<tr><td>' + item + '<br>'; dumped_text += CreateComparisonTable(value,level+1); dumped_text += '</td></tr>'; } else { dumped_text += CreateComparisonTable(value,level, value.length); } } else { dumped_text += '<tr><td>' + level_padding + item + '</td><td>' + value + '</td></tr>'; } } } return dumped_text; } Jsfiddle here

  • User has many computers, computers have many attributes in different tables, best way to JOIN?

    - by krismeld
    I have a table for users: USERS: ID | NAME | ---------------- 1 | JOHN | 2 | STEVE | a table for computers: COMPUTERS: ID | USER_ID | ------------------ 13 | 1 | 14 | 1 | a table for processors: PROCESSORS: ID | NAME | --------------------------- 27 | PROCESSOR TYPE 1 | 28 | PROCESSOR TYPE 2 | and a table for harddrives: HARDDRIVES: ID | NAME | ---------------------------| 35 | HARDDRIVE TYPE 25 | 36 | HARDDRIVE TYPE 90 | Each computer can have many attributes from the different attributes tables (processors, harddrives etc), so I have intersection tables like this, to link the attributes to the computers: COMPUTER_PROCESSORS: C_ID | P_ID | --------------| 13 | 27 | 13 | 28 | 14 | 27 | COMPUTER_HARDDRIVES: C_ID | H_ID | --------------| 13 | 35 | So user JOHN, with id 1 owns computer 13 and 14. Computer 13 has processor 27 and 28, and computer 13 has harddrive 35. Computer 14 has processor 27 and no harddrive. Given a user's id, I would like to retrieve a list of that user's computers with each computers attributes. I have figured out a query that gives me a somewhat of a result: SELECT computers.id, processors.id AS p_id, processors.name AS p_name, harddrives.id AS h_id, harddrives.name AS h_name, FROM computers JOIN computer_processors ON (computer_processors.c_id = computers.id) JOIN processors ON (processors.id = computer_processors.p_id) JOIN computer_harddrives ON (computer_harddrives.c_id = computers.id) JOIN harddrives ON (harddrives.id = computer_harddrives.h_id) WHERE computers.user_id = 1 Result: ID | P_ID | P_NAME | H_ID | H_NAME | ----------------------------------------------------------- 13 | 27 | PROCESSOR TYPE 1 | 35 | HARDDRIVE TYPE 25 | 13 | 28 | PROCESSOR TYPE 2 | 35 | HARDDRIVE TYPE 25 | But this has several problems... Computer 14 doesnt show up, because it has no harddrive. Can I somehow make an OUTER JOIN to make sure that all computers show up, even if there a some attributes they don't have? Computer 13 shows up twice, with the same harddrive listet for both. When more attributes are added to a computer (like 3 blocks of ram), the number of rows returned for that computer gets pretty big, and it makes it had to sort the result out in application code. Can I somehow make a query, that groups the two returned rows together? Or a query that returns NULL in the h_name column in the second row, so that all values returned are unique? EDIT: What I would like to return is something like this: ID | P_ID | P_NAME | H_ID | H_NAME | ----------------------------------------------------------- 13 | 27 | PROCESSOR TYPE 1 | 35 | HARDDRIVE TYPE 25 | 13 | 28 | PROCESSOR TYPE 2 | 35 | NULL | 14 | 27 | PROCESSOR TYPE 1 | NULL | NULL | Or whatever result that make it easy to turn it into an array like this [13] => [P_NAME] => [0] => PROCESSOR TYPE 1 [1] => PROCESSOR TYPE 2 [H_NAME] => [0] => HARDDRIVE TYPE 25 [14] => [P_NAME] => [0] => PROCESSOR TYPE 1

  • Syncronizing XML file with MySQL database

    - by Fred K
    My company uses an internal management software for storing products. They want to transpose all the products in a MySql database so they can do available their products on the company website. Notice: they will continue to use their own internal software. This software can exports all the products in various file format (including XML). The syncronization not have to be in real time, they are satisfied to syncronize the MySql database once a day (late night). Also, each product in their software has one or more images, then I have to do available also the images on the website. Here is an example of an XML export: <?xml version="1.0" encoding="UTF-8"?> <export_management userid="78643"> <product id="1234"> <version>100</version> <insert_date>2013-12-12 00:00:00</insert_date> <warrenty>true</warrenty> <price>139,00</price> <model> <code>324234345</code> <model>Notredame</model> <color>red</color> <size>XL</size> </model> <internal> <color>green</color> <size>S</size> </internal> <options> <s_option>some option</standard_option> <s_option>some option</standard_option> <extra_option>some option</extra> <extra_option>some option</extra> </options> <images> <image> <small>1234_0.jpg</small> </image> <image> <small>1234_1.jpg</small> </image> </images> </product> </export_management> Some ideas for how can I do it?

  • controlling the class names generated by JAXB for xsd:attributeGroup?

    - by Stephen Winnall
    I am using JAXB to bind XML to Java for an application that I am writing. I have an element called measure which contains two amount elements called amount and maxAmount, with which I want to model a lower and an upper limiting value. amount and maxAmount are otherwise identical and I would like them to be implemented with the same class when unmarshalled into Java. The following is an extract from the XML schema which I feed to JAXB: <xsd:attributeGroup name="AmountAttributes"> <xsd:attribute name="quantity" type="xsd:decimal"/> <xsd:attribute name="numerator" type="xsd:nonNegativeInteger"/> <xsd:attribute name="denominator" type="xsd:positiveInteger"/> </xsd:attributeGroup> <xsd:element name="measure"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="amount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> <xsd:element minOccurs="0" name="maxAmount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> JAXB creates from this a more elaborate version of the following: public class Measure { protected Measure.Amount amount; protected Measure.MaxAmount maxAmount; public static class Measure.Amount {} public static class Measure.MaxAmount {} } Measure.Amount and Measure.MaxAmount are identical except for their names, but - of course - as far as Java is concerned they have little to do with each other. Is there a way of making JAXB use the same class for both amount and maxAmount? Just to come completely clean ;-) I should mention that I generate the XML schema from RNC using Trang. If the answer to the question is "change the XML schema", I have the supplementary question "how do I change the RNC to produce that XML schema?". My RNC looks like this: AmountAttributes = QuantityAttribute? & attribute numerator { xsd:nonNegativeInteger }? & attribute denominator { xsd:positiveInteger }? QuantityAttribute = attribute quantity { xsd:decimal } Measure = element measure { element amount { AmountAttributes }?, element maxAmount { AmountAttributes }? }+ I use RNC because I find it simpler to understand, but if the solution to my problem means just using XML Schema, so be it.

  • Detection of battery status totally messed up

    - by Faabiioo
    I already posted this question in the Ubuntu forum and stackOverflow. I forward it here with the hope to find some different opinions about the problem. I have an Acer TravelMate 5730, which is 3 y.o., running Ubuntu 10.04 LTS. One year ago I changed the battery because the old one died. Since then, everything worked like a charm. A week ago I was using my laptop running on battery; it was charged up to 60%. Suddenly it shut down and for about 24h it was like the battery was totally broken: it didn't charge anymore and the 'upower --dump' said state: critical. I was kind of resigned to buy a new battery, when suddenly the orange light became green: battery was charged and actually working; strangely the battery indicator was stuck to 100%, even after 2 hours running. I tried again with 'upower --dump' or 'acpi -b' commands and it kept saying battery is discharging, though maintaining the percentage to 100%. Thus, battery working fine up to 3 hours, without any warning when it was almost empty, likely to result in a brute shut down. Today something different. the 'upower --dump' command says: ... present: yes rechargeable: yes state: fully-charged energy: 0 Wh energy-empty: 0 Wh energy-full: 65.12 Wh energy-full-design: 65.12 Wh energy-rate: 0 W voltage: 14.481 V percentage: 0% capacity: 100% technology: lithium-ion I tried to boot WinXP and the problem is pretty much the same, with the battery fully-charged, percentage equal to 0% and no way to fix it. While writing, the situation has changed again: present: yes rechargeable: yes state: charging energy: 0 Wh energy-empty: 0 Wh energy-full: 65.12 Wh energy-full-design: 65.12 Wh energy-rate: 0 W voltage: 14.474 V percentage: 0% capacity: 100% technology: lithium-ion ...charging, but it does not charge up. (Recall, the battery lasted 3 hours until yesterday!). So, the big question is: is it an hardware issue, like a dedicated internal circuit is broken? or maybe it is just the battery that must be changed. Or, rather, some BIOS problem that could be fixed in some way. I'd appreciate every help that can shed some light on this annoying problem thanks

  • [CentOS 4.8] nslookup resolves domains to IPs, but I can't get a response to pings to external servers

    - by Beco
    I have a fresh install of CentOS 4.8 running on an internal development server. I haven't done anything to it besides setting up sudoers and SSH. I can SSH into the server and from there resolve domains to IPs and ping internal servers, but for some reason I don't get any response from pinging external servers. The software firewall is disabled, and the problem is present with both static and DHCP-assigned network configurations. The network domain controller is a Windows Server 2003 box. $ nslookup google.com Server: 10.254.2.5 Address: 10.254.2.5#53 Non-authoritative answer: Name: google.com Address: 74.125.47.147 Name: google.com Address: 74.125.47.99 <etc...> 10.254.2.5 is the Win2K3 server. $ ping google.com PING google.com (74.125.47.106) 56(84) bytes of data.

The snipped section is our company name. # ifconfig eth0 Link encap:Ethernet HWaddr <snip> inet addr:10.254.2.101 Bcast:10.254.2.255 Mask:255.255.255.0 inet6 addr: <snip>/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:80066 errors:0 dropped:0 overruns:0 frame:0 TX packets:4421 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7810133 (7.4 MiB) TX bytes:590550 (576.7 KiB) Interrupt:225 Base address:0xc000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:32 errors:0 dropped:0 overruns:0 frame:0 TX packets:32 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:8104 (7.9 KiB) TX bytes:8104 (7.9 KiB) # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.254.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 10.254.2.5 0.0.0.0 UG 0 0 0 eth0 And, for good measure, a snapshot of the current ethernet config via the system-config-network GUI. Edit: I don't yet have enough rep to post images, so here's a link. Sorry! system-config-network snapshot I'm pretty green when it comes to setting up *nix dev servers and network configuration in general, so please let me know if I've left out critical information, or posted information I shouldn't have posted. Thanks!
