  • How do you make it so when you click an app on the side it jumps to the opened app

    - by Matt
    I'm not sure what I did but I had it so I could click on the icon that split it into 4 screens and throw whatever I wanted on whichever screen I wanted but I fiddled around with some stuff and made it so that now when I click on the app, say I have Firefox open but it isn't on the active page, it does nothing. Whereas before in the same situation when I clicked on the active app it would sling me across to whichever of the four screens it was located on; how do I get back to this setting?

  • WAIT-VHUB ? Whats Going On ?

    - by Neeraj Gupta
    I know many of you have been working on Oracle's Exalogic and other Engineered Systems. With partitions enabled now, things have gone multi dimension. But its fun. Isn't it ? While you have some EoIB configurations together with InfiniBand partitions, the VNICs are not coming up and staying in WAIT-VHUB state ?  Chances are that you have forgot to add InfiniBand Gateway switches' Bridge-X port GUIDs to your partition. These must be added as FULL members for EoIB to work properly. VHUB means a virtual hub in EoIB. Bridge-x is the access point for hosts to work over EoIB so thats why it must be a full member in partition. Step 1: Find out the port GUIDs of your bridge-x devices in IB Gateway switch. # showgwports INTERNAL PORTS: --------------- Device   Port Portname  PeerPort PortGUID           LID    IBState  GWState --------------------------------------------------------------------------- Bridge-0  1   Bridge-0-1    4    0x0010e00c1b60c001 0x0002 Active   Up Bridge-0  2   Bridge-0-2    3    0x0010e00c1b60c002 0x0006 Active   Up Bridge-1  1   Bridge-1-1    2    0x0010e00c1b60c041 0x0026 Active   Up Bridge-1  2   Bridge-1-2    1    0x0010e00c1b60c042 0x002a Active   Up Step 2: Add these port GUIDs to the IB partition associated with EoIB. Login to master SM switch for this task. # smpartition start # smpartition add -pkey <PKey> -port <port GUID> -m full # smpartition commit Enjoy !

  • Turn-Based RPG Battle Instance Layout For Larger Groups

    - by SoulBeaver
    What a title, eh? I'm currently designing a videogame; a turn-based RPG like Final Fantasy (because everybody knows Final Fantasy). It's a 2D sprite game. These are my ideas for combat: -The player has a group of 15 members (main character included) -During battle, five of the group are designated as active, and appear in the battle. -These five may be switched out at leisure, or when one of the five die. -At any time, the Waiting members can cast buffs, be healed by the active members, or perform special attacks. -Battles should contain 10+ monsters at least. I'm aiming for 20, but I'm not sure if that's possible yet. -Battles should feel larger than normal due to the interaction of Waiting members, active members and the increased amount of monsters per battle. -The player has two rows in which to put the Active members: front and back. -Depending on the implementation, I might allow comboing of player attacks and skills. These are just design ideas, so beware! I have not been able to test this out yet- I have no idea yet if any of these ideas bunched together will make for a compelling game. What sounds good on paper doesn't necessarily have to be good in practice! What I'm asking now is how to create the layout for this. My starting point are the battles in Final Fantasy VI, with up to 5-6 monsters on the left and the characters on the right- monsters on both sides if it's a pincer attack. However, this view would not work feasible with my goal of 20 monsters and 5 characters. All the monsters on the left would appear cluttered unless I scale them far far back. If I create a pincer-like map, then there would be no real pincer-attack possible. If I space the monsters out I force the player to scroll the screen- a game mechanic I've come across and not enjoyed imho. My question is: does anybody have any layouts or guides for designing battle maps in turn-based RPGs, especially with a larger number of enemies taken into consideration? How should it look? I am not asking for specific combat mechanics, just the layout for the moment.

  • Where should I start with debugging my exchange server?

    - by joadha
    I'm (foolishly?) attempting to install Exchange on top of Windows Server 2008 (64-bit) over Virtual Box running on Mac OSX Lion. Everything went smoothly until I got to the "Readiness Checks" tab. Readiness failed spectacularly on Hub Transport Role and Mailbox Role prereqs. Before I go too far down the rabbit hole in attempting to remedy this, I was hoping I could get some input on where to start in all of this. I already set up the following Active Directory roles, but it didn't seem to help: Active Directory Domain Services Active Directory Lightweight Directory Services I also enabled an Application Server role. Those three are the only roles I've set up-- I cannot locate within Server Manager the Organization Manager role or any of the other roles referenced in the list of borkedness below. Is this a typical experience in Exchange installation? Is there a tutorial created by somebody outside of Microsoft? Here's the output from Readiness Checks: Summary: 5 item(s). 2 succeeded, 3 failed.

  • How to represent a tree structure in NoSQL

    - by Vlad Nicula
    I'm new to NoSQL and have been playing around with a personal project on the MEAN stack (Mongo ExpressJs AngularJs NodeJs). I'm building a document editor of sorts that manages nodes of data. Each document is actually a tree. I have a CRUD api for documents, to create new trees and a CRUD api for nodes in a given document. Right now the documents are represented as a collection that holds everything, including nodes. The children parent relationship is done by ids. So the nodes are an map by id, and each node has references to what nodes are their children. I chose this "flat" approach because it is easier to get a node by id from a document. Being used to having a relation table between nodes and documents, a relation table between nodes and children nodes I find it a bit weird that I have to save the entire "nodes" map each time I update a node. Is there a better way to represent such a data type in NoSQL?

  • RTS game diplomacy heuristics

    - by kd304
    I'm reimplementing an old 4X space-rts game which has diplomacy options. The original was based on a relation scoring system (0..100) and a set of negotiation options (improve relations, alliance, declare war, etc.) The AI player usually had 3 options: yes, maybe and no; each adding or removing some amount to the relation score. How should the AI chose between the options? How does the diplomacy work in other games and how are they imlemented? Any good books/articles on the subject? (Googling the term diplomacy yields the game Diplomacy, which is unhelpful.)

  • Asynchronously returning a hierarchal data using .NET TPL... what should my return object "look" like?

    - by makerofthings7
    I want to use the .NET TPL to asynchronously do a DIR /S and search each subdirectory on a hard drive, and want to search for a word in each file... what should my API look like? In this scenario I know that each sub directory will have 0..10000 files or 0...10000 directories. I know the tree is unbalanced and want to return data (in relation to its position in the hierarchy) as soon as it's available. I am interested in getting data as quickly as possible, but also want to update that result if "better" data is found (better means closer to the root of c:) I may also be interested in finding all matches in relation to its position in the hierarchy. (akin to a report) Question: How should I return data to my caller? My first guess is that I think I need a shared object that will maintain the current "status" of the traversal (started | notstarted | complete ) , and might base it on the System.Collections.Concurrent. Another idea that I'm considering is the consumer/producer pattern (which ConcurrentCollections can handle) however I'm not sure what the objects "look" like. Optional Logical Constraint: The API doesn't have to address this, but in my "real world" design, if a directory has files, then only one file will ever contain the word I'm looking for.  If someone were to literally do a DIR /S as described above then they would need to account for more than one matching file per subdirectory. More information : I'm using Azure Tables to store a hierarchy of data using these TPL extension methods. A "node" is a table. Not only does each node in the hierarchy have a relation to any number of nodes, but it's possible for each node to have a reciprocal link back to any other node. This may have issues with recursion but I'm addressing that with a shared object in my recursion loop. Note that each "node" also has the ability to store local data unique to that node. It is this information that I'm searching for. In other words, I'm searching for a specific fixed RowKey in a hierarchy of nodes. When I search for the fixed RowKey in the hierarchy I'm interested in getting the results FAST (first node found) but prefer data that is "closer" to the starting point of the hierarchy. Since many nodes may have the particular RowKey I'm interested in, sometimes I may want to get a report of ALL the nodes that contain this RowKey.

  • Logic or Algorithm to solve this problem [closed]

    - by jade
    I have two lists. List1 {a,b,c,d,e} and List2 {f,g,h,i,j} The relation between the two list is as follows a->g,a->h,h->c,h->d,d->i,d->j Now I have these two lists displayed. Based on the relation above on selecting element a from List1, List2 shows g,h. On selecting h from List2, in List1 c,d are shown in List1. On selecting d from List1 it shows i,j in List2. How to trace back to initial state by deselecting the elements in reverse order in which they have been selected?

  • Can software company claim the intellectual property rights on my paintings?

    - by maksymko
    This is somewhat related to this question. I'm about to sign a contract with a company that this sort of "all your base are belong to us" clause in it: it says that all programs, designs, sketches, drawings I create in relation to my job belong to the company. More or less usual stuff (unfortunately). What worries me, however, is this "drawings, sketches" thing, because I'm a hobby-artist and I paint and draw at my spare time. Can the company somehow claim ownership of intellectual rights on this work? Should I ask them to explicitly state that this clause does not extend to work of art or is this "in relation to the job" part is good enough?

  • C Programming arrays, I dont understand how I would go about making this program, If anyone can just guide me through the basic outline please :) [on hold]

    - by Rashmi Kohli
    Problem The temperature of a car engine has been measured, from real-world experiments, as shown in the table and graph below: Time (min) Temperature (oC) 0 20 1 36 2 61 3 68 4 77 5 110 Use linear regression to find the engine’s temperature at 1.5 minutes, 4.3 minutes, and any other time specified by the user. Background In engineering, many times we measure several data points in an experiment, but then we need to predict a value that we have not measured which lies between two measured values, such as the problem statement above. If the relation between the measured parameters seems to be roughly linear, then we can use linear regression to find the relationship between those parameters. In the graph of the problem statement above, the relation seems to be roughly linear. Hence, we can apply linear regression to the above problem. Assuming y {y0, y1, …yn-1} has a linear relation with x {x0, x1, … xn-1}, we can say that: y = mx+b where m and b can be found with linear regression as follows: For the problem in this lab, using linear regression gives us the following line (in blue) compared to the measured curve (in red). As you can see, there is usually a difference between the measured values and the estimated (predicted) values. What linear regression does is to minimize those differences and still give us a straight line (blue). Other methods, such as non-linear regression, are also possible to achieve higher accuracy and better curve fitting. Requirements Your program should first print the table of the temperatures similar to the way it’s printed in the problem statement. It should then calculate the temperature at minute 1.5 and 4.3 and show the answers to the user. Next, it should prompt the user to enter a time in minutes (or -1 to quit), and after reading the user’s specified time it should give the value of the engine’s temperature at that time. It should then go back to the prompt. Hints •Use a one dimensional array to store the temperature values given in the problem statement. •Use functions to separate tasks such as calculating m, calculating b, calculating the temperature at a given time, printing the prompt, etc. You can then give your algorithm as well as you pseudo code per function, as opposed to one large algorithm diagram or one large sequence of pseudo code.

  • Dropdown dependent values to be fetch from multiple models using ajax in Yii

    - by newuser
    I searched all the documentation over Yii but not got the answer of it.So I came here finally. I have the following schema Table Schools +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_name | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ Table Students +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_id | int(10) | NO | FK | | | | student_name | varchar(100) | NO | | | | | roll_no | varchar(80) | NO | | | | | class | varchar(20) | NO | | | | | | subjects | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ I have made models and CRUD for the both models.In models my relation is like this In Students.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'School' => array(self::BELONGS_TO,'Schools','school_id'), ); } In Schools.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'student' => array(self::HAS_MANY, 'Students', 'school_id'), ); } Now I made the two models rendered in a single page so that I can enter all the respective fields in a single form. In the _form.php file of Students I have made some change in student_name like this <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php echo $form->dropdownList($model,'student_name', CHtml::listData(Students::model()->findAll(), 'id', 'student_name'), array('empty'=>array('Select'=>'--Select One---'))); ?> <?php echo $form->error($model,'student_name'); ?> Now for this piece of code I got all the student name from the Student model. So my problem is when I am getting the student name from the dropdown list and going to select a student it will also fetch all the respective values of the student to be rendered in the _form.php without click on save button.So that user don't have to put it again manually. I think ajax and json encode will work here but don't know how to make them work here. [Update] Here is StudentsController code public function actionDisCoor() { $model = School::model()->findByPk($_POST['Students']['student_id']); $data=CHtml::listData($data,'id','name'); foreach($data as $value=>$name) { echo CHtml::tag('option',array('value'=>$value),CHtml::encode($name),true); } } Here is _form.php code for Students <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php $List = CHtml::listData(Students::model()->findAll(), 'id', 'student_name'); ?> <?php echo $form->dropdownList($model,'student_name',$List, array('onChange'=>CHtml::ajax(array( 'url' => CController::createUrl('DisCoor'), 'type' => 'POST', 'update'=>'#school_id', )),'style'=>'width:180px;' ) )?> <?php echo $form->error($model,'student_name'); ?> </div> After all that when I saw in firebug I got the error.Here is the screen shot

  • content show problem

    - by nonab
    I still fight with some jquery scripts:) With my first problem Jens Fahnenbruck helped me here: http://stackoverflow.com/questions/3021476/problem-with-hide-show-in-jquery thanks:) Now i added another fancy thing - jquery tabs Made a few modifications and it works like this: When you click on tab and it loads different main image for every tab. The problem is that i used $(document).ready(function() to handle those image changes. When i click any of 2x2 box images (on any tab) it will permanently change the image on the right and when i click on tabs it won't work like it did at the beginning. online example: http://rarelips.ayz.pl/testy/2/ code: <style type="text/css"> body { font: Arial, Helvetica, sans-serif normal 10px;

  • Understanding Linux SCSI queue depths

    - by Troels Arvin
    I'm experimenting with the effects of different SCSI queue depth values on a Dell server running CentOS Linux 5.4 (x86_64). The server has two QLogic QLE2560 FC HBAs connected via multipathing to a storage system. The storage system has allocated two LUNs to the server, each connected through four paths in an active-active-active-active round-robin configuration. All in all, the two LUNs exist as eight /dev/sdX devices, represented by two devices in /dev/mpath. I currently adjust the queue depth values in /etc/modprobe.conf and check the result (after rebooting) by looking in the seventh column of /proc/scsi/sg/devices. Two questions related to that: Is there a way to adjust queue depths without rebooting or unloading the qla2xxx kernel module? E.g., can I echo a new queue depth value into some /proc or /sys-like file to update the queue depth? If I set the queue depth to 128, is that 128 in total for all devices handled by the qla2xxx module?, or 128 for each HBA? (256 in total), or 128 for each of the eight /dev/sdX devices (1024 in toal)?, or 128 for each of the two /dev/mpath/... devices (256 in total)? This is important for me to know so that my server doesn't flood the storage system, affecting other servers connected to it.

  • IPMI not fucntioning with Network Bonding

    - by muhammed sameer
    Hey, I am having problems with running IPMI on my servers that have network bonding enabled. Platform: CentOS release 5.3 (Final) Kernel: 2.6.18-92.el5 64bit Dell PowerEdge 1950 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet I have bonded the interface eth0 and eth1 as active passive, with eth0 as the active interface, below is conf description from /proc Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 30 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:22:19:56:b9:cd Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:22:19:56:b9:cf My IPMI device is as follows IPMI Device Information Interface Type: KCS (Keyboard Control Style) Specification Version: 2.0 I2C Slave Address: 0x10 NV Storage Device: Not Present Base Address: 0x0000000000000CA8 (I/O) Register Spacing: 32-bit Boundaries I Have used openIPMI as well as freeipmi both to control the chassis via the IPMI card, but on servers which have bonding enabled, the command times out, below is the full run of the command with debug info. ipmi_lan_send_cmd:opened=[0], open=[4482848] IPMI LAN host 70.87.28.115 port 623 Sending IPMI/RMCP presence ping packet ipmi_lan_send_cmd:opened=[1], open=[4482848] No response from remote controller Get Auth Capabilities command failed ipmi_lan_send_cmd:opened=[1], open=[4482848] No response from remote controller Get Auth Capabilities command failed Error: Unable to establish LAN session Failed to open LAN interface Unable to get Chassis Power Status On the other hand I configured IPMI on a box with the same specs as mentioned above without bonding and IPMI works perfectly. Has anyone faced this problem with IPMI + Bonding ? I would be thankful is someone helps circumvent this issue. Muhammed Sameer

  • mysqld causes high CPU load

    - by Radu
    My mysqld goes to use 99.9% of CPU for variable time (between 2 - 20 minutes), and then goes back to normal 0.1% - 5%. Checked processlist: all is normal, 1 to 20 inserts or updates that last 2 to 5 sec, and about 20 process that are in Sleep Mode (maybe because the scripts don't close the mysql connection, but are they are closed in about 5 - 10 secs, I didn't make the scripts :P but the server was running fine the last 2 years, since is was made): | 15375 | root | localhost | stoc | Query | 0 | NULL | show processlist | | 79480 | pppoe | localhost | pppoe | Sleep | 4 | NULL | NULL | | 79481 | pppoe | localhost | pppoe | Sleep | 4 | NULL | NULL | | 79482 | pppoe | localhost | pppoe | Sleep | 4 | NULL | NULL | | 79483 | pppoe | localhost | pppoe | Query | 0 | init | UPDATE acc SET InputOctets="0", OutputOctets="0", InputPackets="unknown", OutputPackets="User | | 79484 | pppoe | localhost | pppoe | Sleep | 5 | NULL | NULL | | 79485 | pppoe | localhost | pppoe | Sleep | 5 | NULL | NULL | | 79486 | pppoe | localhost | pppoe | Sleep | 5 | NULL | NULL Checked raid, seemns OK: [root@db2]# cat /proc/mdstat Personalities : [raid5] [raid4] [raid1] md0 : active raid1 sdd1[3] sdc1[2] sdb1[0] sda1[1] 136448 blocks [4/4] [UUUU] md1 : active raid5 sdd2[3] sdc2[2] sdb2[0] sda2[1] 12023808 blocks level 5, 256k chunk, algorithm 2 [4/4] [UUUU] md3 : active raid5 sda4[1] sdd4[3] sdc4[2] sdb4[0] 203647488 blocks level 5, 256k chunk, algorithm 2 [4/4] [UUUU] md2 : active raid5 sda3[1] sdd3[3] sdc3[2] sdb3[0] 24024576 blocks level 5, 256k chunk, algorithm 2 [4/4] [UUUU] unused devices: <none> [root@db2]# top sees my mysqld cpu load, but nothing else seems to be wrong: [root@db2]# top top - 17:56:05 up 7 days, 3:55, 3 users, load average: 32.93, 24.72, 22.70 Tasks: 75 total, 4 running, 71 sleeping, 0 stopped, 0 zombie Cpu(s): 63.4% us, 36.6% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si, 0.0% st Mem: 1988824k total, 1304776k used, 684048k free, 99588k buffers Swap: 12023800k total, 0k used, 12023800k free, 951028k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5754 mysql 19 0 236m 57m 5108 R 99.9 2.9 21:58.76 mysqld 1 root 16 0 7216 700 580 S 0.0 0.0 0:00.39 init 2 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/0 Repaired all mysql databases, reindexed raid ...
