  • Excel Extending Equations

    - by Richard
    So I have an excel table that is multiply 1 value against several other values. It looks like this: So I want the equations inside cells C14 to F14 to be B14*C5, B14*C6, B14*C7, B14*C8 respectively. So I can obviously do that manually but I want to learn the faster way. So I know I should use absolute reference for B14, so I can input =$B$14*C5 for cell C14. But then when I do the CTRL extend method where you put the cursor on the bottom right corner of the cell and hold CTRL while you extend the cells. The problem is since I am extending the equation in B14 horizontally to F14, it is incrementing the equation horizontally. So the equation in D14 becomes =$B$14*D5 instead of =$B$14*C6. So how exactly do I increment the equation downwards while I extend the equation horizontally?

  • Install Base Transaction Error Troubleshooting

    - by LuciaC
    Oracle Installed Base is an item instance life cycle tracking application that facilitates enterprise-wide life cycle item management and tracking capability.In a typical process flow a sales order is created and shipped, this updates Inventory and creates a new item instance in Install Base (IB).  The Inventory update results in a record being placed in the SFM Event Queue.  If the record is successfully processed the IB tables are updated, if there is an error the record is placed in the csi_txn_errors table and the error needs to be resolved so that the IB instance can be created.It's extremely important to be proactive and monitor IB Transaction Errors regularly.  Errors cascade and can build up exponentially if not resolved. Due to this cascade effect, error records need to be considered as a whole and not individually; the root cause of any error needs to be resolved first and this may result in the subsequent errors resolving themselves. Install Base Transaction Error Diagnostic Program In the past the IBtxnerr.sql script was used to diagnose transaction errors, this is now replaced by an enhanced concurrent program version of the script. See the following note for details of how to download, install and run the concurrent program as well as details of how to interpret the results: Doc ID 1501025.1 - Install Base Transaction Error Diagnostic Program  The program provides comprehensive information about the errors found as well as links to known knowledge articles which can help to resolve the specific error. Troubleshooting Watch the replay of the 'EBS CRM: 11i and R12 Transaction Error Troubleshooting - an Overview' webcast or download the presentation PDF (go to Doc ID 1455786.1 and click on 'Archived 2011' tab).  The webcast and PDF include more information, including SQL statements that you can use to identify errors and their sources as well as recommended setup and troubleshooting tips.

  • What hardware is at physical address 0x80000000 on powerpc New World Macintosh?

    - by tinkerer
    Open Firmware device tree gives no clue what device might decode at physical address 0x80000000 to 0x8008200 on a G4 New World Macintosh. The mmu has three adjacent Virtual=Real translations for that block. They are the only address translations reported between the top or physical dram at 20000000 and the start of the PCI bridges at f0000000. (A possible clue is that frame-buffer-addr is reported as 9c008000 by Open Firmware, and that is not in the reported translation table either). I believe the architecture has been around since about 1999.

  • Can I format a USB key in GUID mode in windows 7 to make it Mac OSX boot friendly?

    - by digiguru
    I have a macbookpro that wont boot properly. I've tried resetting the PRAM (holding down option - alt - P - R), but it doesn't work, it gets halfway through the boot process and says "You need to restart your computer" in several languages. Recently I downloaded a USB Key compatible Linux OS. This USB Key works as a boot loader on Windows machines, but on OSX it can only find the Harddrive partitions when I go into the boot loader menu (holding down Option on startup). I am assuming it is because it is formatted as FAT32, and not GUID Table. I believe my CD drive is also bust, it hasn't worked in a long time. I don't have another Mac computer, so is there a way I can format the USB key as GUID Partition from a windows 7 machine?

  • Repairing a corrupt exFat file system

    - by Wandyer
    Long story short : I messed up my GPT and went on to try to fix it without asking anyone, just searching around. Didn't turn out too well. Right now all I'm concerned about is a 500GB that I formatted as exFat partition with some important files. But on my journey to fix, I may have used the 'fdisk' command on a GParted Live CD I have (couldn't get on any OS) and switched it to ext2. Now I can't get access to it, doesn't show up on Windows or Mac. Only on the partition table as ext2. I have got access to most of my files through recovery softwares but they cannot recover with the originial directory or file names, which would be a pain to fix. I want to know if there is a way to change back the file system to exFat without having to format it. Thanks in advance. EDIT: This is how my partitions look like right.

  • Deploy multiple emails to email providers, but without showing favouritism

    - by Ardman
    We are currently developing a new email deployment system. We have the system currently configured so that it reads a record from the database and loads the email content and deploys it to the target. Now we want to move this over to multiple threads. That is easily done, except we then hit the email providers returning SMTP codes referring to "Too many connections", or "Deferred connection". The solution to this is to have a thread open up a connection to the email provider and deploy n emails and then disconnect. We have currently configured the application so that it will support these session based email deployments. The problem is this, the database table has multiple email addresses in and they aren't grouped by email provider because that will show favouritism. We need to be able to retrieve a set number of, i.e. Hotmail, emails (@hotmail.com, @hotmail.co.uk, @live.co.uk) so that we are reducing the number of connections to Hotmail and reducing the risks of getting the "Too many connections" error. We are at the point now where we have gone round and round in circles trying to get a solution, so I thought I'd throw it out there and see if anyone has any ideas? EDIT I would like to stress that this application is not used for spamming purposes.

  • How to backup MySQL (mysqldump) when Memcached installed?

    - by cewebugil
    The server OS is CentOS, with Memcached installed Before Memcached installed, I use mysqldump -u root -p --lock-tables --add-locks --disable-keys --skip-extended-insert --quick wcraze > /var/backup/backup.sql But now, Memcached has been installed. According to Wikipedia; When the table is full, subsequent inserts cause older data to be purged in least recently used (LRU) order. This means new data entry is not directly saved in MySQL, but saved in Memcached instead, until limit_maxbytes is full, the least accessed data will be saved in MySQL. This means, some data is not in the MySQL but in Memcached. So, when backup, the new entry is not in the backup data What is the right way to backup?

  • Architectural approaches to creating a game menu/shell overlay on PC/Linux?

    - by Ghopper21
    I'm am working on a collection of games for a custom digital tabletop installation (similar to Microsoft Surface tables). Each game will be an individual executable that runs full-screen. In addition, there needs to be a menu/shell overlay program running simultaneously. The menu/shell will allow users to pause games, switch to other games, check their game history, etc. Some key requirements of the shell: it intercepts all user input (mainly multitouch) first before passing it on to the currently running game (so that it can, for instance, know to pop-up at a "pause" command); can reveal on arbitrary portions of the screen, with the currently running (but presumably paused) game still showing underneath, ideally with its shape/size being dynamic, to allow for creation of an animated in/out drawer effect over the game. I'm currently looking into different architectural approaches to this problem, including Fraps and DirectX overlays, but I'm sure I'm missing some ways to think about this. What are the main approaches I should be considering? (Note the table is currently being run by Windows PC, but it could potentially be a Linux box instead.)

  • Can I buy a wireless access point that also acts as a DNS nameserver?

    - by Brabster
    Hi, I was wondering if I buy a wireless access point/router that also acts as a DNS nameserver for DHCP clients. I can see the hostnames of my home devices in the DHCP clients table of the router I have, it doesn't seem like a great leap of the imagination to have a local nameserver on there, something like hostname.home that automatically publishes those entries to a local zone. But - I can't find one that does that. Is there a reason why this shouldn't/can't be done? Or is my Google-Fu just weak? Cheers,

  • Wireless controllers vs wireless usb hub

    - by David Jensen
    For my htpc i currently only have a steerin wheel as a controller. This is wired and it looks really bad having extended usb wires from the tv to the table. However im thinking of bying some new Gamepads and now comes the question. Should i buy wireless ones or wired and connect them to a wireless usb hub? Having a wireless hub would let me manage my gamepads easily from the couch. A wireless hub also allows me to connect other things that are not input devices from the couch. However im wondering if wireless usb hubs may not be made for input devices in the way that they may not have 100% uptime and probably some delay. Am i right about this?

  • SQL Server 2008, not enough disk space

    - by snorlaks
    Hello, I'm executing sql query on my database. I have SQL Server 2008 installed on my D harddrive which has 55 GB free space. I have also C drive which has sth like 150 MB free (right now). While executing that query on quite a big table (16 GB) I have an error: An error occurred while executing batch. Error message is: Not enough disk space. I would like to know if there is any possibility that I can make SQL Server to use D drive instead of C Or maybe there is any other problem with what I'm doing ? Thanks for help

  • IIS7.5 App Pool recycling. What is the best schedule for Recycling

    - by mikedopp
    I have been using IIS7.5 Since its release. I am also using commerce server 2007sp2. Due to Commerce Servers Need for memory and processor I have the app pool the website is assigned to recycling at midnight every night. My Question is what is the best time table to recycle heavy web app pools? I am looking to keep speed and not bump potential customers while recycling multiple times a day if possible. Another issue is that every few days the same app pool will hang and I have to force a reset of IIS to get it working again.

  • Caching by in-memory dictionaries. Are we doing it all wrong?

    - by user73983
    This approach is pretty much the accepted way to do anything in our company. A simple example : when a piece of data for a customer is requested from a service, we fetch all the data for that customer(relevant part to the service) and save it in a in-memory dictionary then serve it from there on following requests(we run singleton services). Any update goes to DB, then updates the in memory dictionary. It seems all simple and harmless but as we implement more complicated business rules the cache gets out of sync and we have to deal with hard to find bugs. Sometimes we defer writing to database, keeping new data in cache till then. There are cases when we store millions of rows in memory because the table has many relations to other tables and we need to show aggregate data quickly. All this cache handling is a big part of our codebase and I sense this is not the right way to do it. All of this juggling adds too much noise to the code and it makes it hard to understand the actual business logic. However I don't think we can serve data in a reasonable amount of time if we have to hit the database every time. I am unhappy about the current situation but I don't have a better alternative. My only solution would be to use NHibernate 2nd level cache but I have nearly no experience with it. I know many campanies use Redis or MemCached heavily to gain performance but I have no idea how I would integrate them into our system. I also don't know if they can perform better than in-memory data structures and queries. Are there any alternative approaches that I should look into?

  • Architecture : am I doing things right?

    - by Jeremy D
    I'm trying to use a '~classic' layered arch using .NET and Entity Framework. We are starting from a legacy database which is a little bit crappy: Inconsistent naming Unneeded views (view referencing other views, select * views etc...) Aggregated columns Potatoes and Carrots in the same table etc... So I ended with fully isolating my database structure from my domain model. To do so EF entities are hidden from presentation layer. The goal is to permit an easier database refactoring while lowering the impact of it on applications. I'm now facing a lot of challenges and I'm starting to ask myself if I'm doing things right. My Domain Model is highly volatile, it keeps evolving with apps as new fields needs are arising. Complexity of it keeps raising and class it contains start to get a lot of properties. Creating include strategy and reprojecting to EF is very tricky (my domain objects don't have any kind of lazy/eager loading relationship properties): DomainInclude<Domain.Model.Bar>.Include("Customers").Include("Customers.Friends") // To... IFooContext.Bars.Include(...).Include(...).Where(...) Some framework are raping the isolation levels (Devexpress Grids which needs either XPO or IQueryable for filtering and paging large data sets) I'm starting to ask myself if : the isolation of EF auto-generated entities is an unneeded cost. I should allow frameworks to hit IQueryable? Slow slope to hell? (it's really hard to isolate DevExpress framework, any successful experience?) the high volatility of my domain model is normal? Did you have similar difficulties? Any advice based on experience?

  • Get error (Repair Filesystem) 1 # when I install 4 new Hard drives in RedHat Linux 5 on a Dell PowerEdge 2900

    - by Alos Diallo
    Hi I am using a Dell PowerEdge 2900 running RedHat 5. I had 4 drives in the system using a Raid 5, I purchased and installed 4 more drives keeping the configuration the same. Set up the Vertual disks in PERC 6/i. When I exit out and reboot the system I get the following: fsck.ext3: No such file or dirrectory while trying open /dev/ddb1 [FAILED] ***An error occurred during the file system check. ***Dropping you to a shell; the system will reboot ***when you leave the shell. Then am prompted for the root pw. I enter it and am then prompted with: (Repair filesystem) 1# if I type fdisk -l I get some info on the disk along with: Disk /dev/sdb doesn't contain a valid partition table I am then prompted for (Repair filesystem) 2# If I reboot I am taken to the same screen again. The system was working before this happened. Does anyone know why this is happening and or what I can do to fix it? Thanks

  • Cheap ways to do scaling ops in shader?

    - by Nick Wiggill
    I've got an extensive world terrain that uses vec3 for the vertex position attribute. That's good, because the terrain has endless gradations due to the use of floating point. But I'm thinking about how to reduce the amount of data uploaded to the GPU. For my terrain, which uses discrete / grid-based vertex positions in x and z, it's pretty clear that I can replace my vec3s (floats, really) with shorts, halving the per-vertex position attribute cost from 12 bytes each to 6 bytes. Considering I've got little enough other vertex data, and an enormous amount of terrain data to push into the world, it's a major gain. Currently in my code, one unit in GLSL shaders is equal to 1m in the world. I like that scale. If I move over to using shorts, though, I won't be able to use the same scale, as I would then have a very blocky world where every step in height is an entire metre. So I see these potential solutions to scale the positional data correctly once it arrives at the vertex shader stage: Use 10:1 scaling, i.e. 1 short unit = 1 decimetre in CPU-side code. Do a division by 10 in the vertex shader to scale incoming decimetre values back to metres. Arbirary (non-PoT) divisions tend to be slow, however. Use (some-power-of-two):1 scaling (eg. 8:1), which enables the use of a bitshift (eg. val >> 3) to do the division... not sure how performant this is in shaders, though. Not as intuitive to read values, but possibly quite a bit faster than div by a non-PoT value. Use a texture as lookup table. I've heard that this is really fast. Or whatever solutions others can offer to achieve the same results -- minimal vertex data with sensible scaling.

  • Displaying a Grid of Data in ASP.NET MVC

    One of the most common tasks we face as a web developers is displaying data in a grid. In its simplest incarnation, a grid merely displays information about a set of records - the orders placed by a particular customer, perhaps; however, most grids offer features like sorting, paging, and filtering to present the data in a more useful and readable manner. In ASP.NET WebForms the GridView control offers a quick and easy way to display a set of records in a grid, and offers features like sorting, paging, editing, and deleting with just a little extra work. On page load, the GridView automatically renders as an HTML <table> element, freeing you from having to write any markup and letting you focus instead on retrieving and binding the data to display to the GridView. In an ASP.NET MVC application, however, developers are on the hook for generating the markup rendered by each view. This task can be a bit daunting for developers new to ASP.NET MVC, especially those who have a background in WebForms. This is the first in a series of articles that explore how to display grids in an ASP.NET MVC application. This installment starts with a walk through of creating the ASP.NET MVC application and data access code used throughout this series. Next, it shows how to display a set of records in a simple grid. Future installments examine how to create richer grids that include sorting, paging, filtering, and client-side enhancements. We'll also look at pre-built grid solutions, like the Grid component in the MvcContrib project and JavaScript-based grids like jqGrid. But first things first - let's create an ASP.NET MVC application and see how to display database records in a web page. Read on to learn more! Read More >

  • How to set which IP to use for a HTTP request?

    - by GetFree
    This is probably a silly question. I'm doing some http requests using wget from the command line, and I want those connections to be made through one specific IP of the 4 IPs my server has. Those http requests go to one specific range of IPs so I only want those to be routed differently. The 4 interfaces in my server are eth0, eth0:0, eth0:1, eth0:2. I tried with the following command: route add -net 192.164.10.0/24 dev eth0:0 But when I see the routing table it says: Destination Gateway Genmask Flags MSS Window irtt Iface 192.164.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 The interface is set to eth0 not eth0:0 as my command says. What am I doing wrong?

  • C++: calling non-member functions with the same syntax of member ones

    - by peoro
    One thing I'd like to do in C++ is to call non-member functions with the same syntax you call member functions: class A { }; void f( A & this ) { /* ... */ } // ... A a; a.f(); // this is the same as f(a); Of course this could only work as long as f is not virtual (since it cannot appear in A's virtual table. f doesn't need to access A's non-public members. f doesn't conflict with a function declared in A (A::f). I'd like such a syntax because in my opinion it would be quite comfortable and would push good habits: calling str.strip() on a std::string (where strip is a function defined by the user) would sound a lot better than calling strip( str );. most of the times (always?) classes provide some member functions which don't require to be member (ie: are not virtual and don't use non-public members). This breaks encapsulation, but is the most practical thing to do (due to point 1). My question here is: what do you think of such feature? Do you think it would be something nice, or something that would introduce more issues than the ones it aims to solve? Could it make sense to propose such a feature to the next standard (the one after C++0x)? Of course this is just a brief description of this idea; it is not complete; we'd probably need to explicitly mark a function with a special keyword to let it work like this and many other stuff.

  • Set UFW before.rules without restart of server

    - by enedene
    I use UFW on my Ubuntu server. Unfortunately there are no rules in UFW to port forward to another machine.

  • Problems dualbooting Ubuntu because of UEFI

    - by Koffeehaus
    I have an X-series Asus laptop which I just bough about a month ago. I want to dualboot Ubuntu - Windows. I can easily access LiveUSB with both UEFI enabled and disabled. I heard that there were problems with UEFI, so I disabled it. After I've installed the system I couldn't access it. It just boots to Windows straight. Another unusual thing, that never happened to me before was that the partition editor wanted me to create a BIOS reserved area, which I did, but not at the beginning of the table. Any ideas how to access the Ubuntu partition? As far as I can guess both Windows and Ubuntu have to be both of the same type of boot, either Legacy or EFI. This is not the case of what I have now. So, if I reinstall Ubuntu in UEFI mode that correlates with my Windows type, will I then be able to boot into it? I have a constraint, my laptop doesn't have a CD ROM, so I cannot reinstall WIndows, nor can I move around the Windows recovery partition. This is the boot-repair report : http://paste.ubuntu.com/1354254/

  • Database and query to store and retreive friend list [migrated]

    - by amr Kamboj
    I am developing a module in website to save and retreive friend list. I am using Zend Framework and for DB handling I am using Doctrine(ORM). There are two models: 1) users that stores all the users 2) my_friends that stores the friend list (that is refference table with M:M relation of user) the structure of my_friends is following ...id..........user_id............friend_id........approved.... ...10.........20 ..................25...................1.......... ...10.........21 ..................25...................1.......... ...10.........22 ..................30...................1.......... ...10.........25 ..................30...................1.......... The Doctrine query to retreive friend list id follwing $friends = Doctrine_Query::create()->from('my_friends as mf') ->leftJoin('mf.users as friend') ->where("mf.user_id = 25") ->andWhere("mf.approved = 1"); Suppose I am viewing the user no.- 25. With this query I am only getting the user no.- 30. where as user no.- 25 is also approved friend of user no.- 20 and 21. Please guide me, what should be the query to find all friend and is there any need to change the DB structure.
