  • Office 2010 Client &ndash; Should I go with 32 bit or 64 bit?

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). As you know, Office 2010 client now comes in both 32 bit and 64 bit versions. The question is, should you go with 32 bit or 64 bit? 64 is bigger than 32 .. so 64 is better no? NO! Given a choice, or unless you have a very strong reason not to – GO WITH 32 bit. Why is that? Here is why - 32 bit apps actually work better on 64 bit OS’s in most scenarios due to WoW, and the additional 64 bit VLSW calculations. If you have 2007 installations to support, SharePoint designer 2010 cannot be used to work with SharePoint 2007 sites. So you will have to install SharePoint designer 2007 32bit side by side with SharePoint designer 2010 32 bit side by side. So you cannot mix and match 32 bit and 64 bit here. Of course you can virtualize and not have this problem to begin with :-D. 64 bit office will break many things on your SharePoint experience for that client – example, that fancy datasheet view won’t work on lists. 32 bit office apps don’t have this issue. There are some extreme situations where you DO want 64 bit client apps though. Specifically if you have HUGE excel sheets to work with, then 64 bit office client excel is much better than the equivalent 32 bit excel. Comment on the article ....

  • Searching for entity awareness in 3D space algorithm and data structure

    - by Khanser
    I'm trying to do some huge AI system just for the fun and I've come to this problem. How can I let the AI entities know about each other without getting the CPU to perform redundant and costly work? Every entity has a spatial awareness zone and it has to know what's inside when it has to decide what to do. First thoughts, for every entity test if the other entities are inside the first's reach. Ok, so it was the first try and yep, that is redundant and costly. We are working with real time AI over 10000+ entities so this is not a solution. Second try, calculate some grid over the awareness zone of every entity and test whether in this zones are entities (we are working with 3D entities with float x,y,z location coordinates) testing every point in the grid with the indexed-by-coordinate entities. Well, I don't like this because is also costly, but not as the first one. Third, create some multi linked lists over the x's and y's indexed positions of the entities so when we search for an interval between x,y and z,w positions (this interval defines the square over the spatial awareness zone) over the multi linked list, we won't have 'voids'. This has the problem of finding the nearest proximity value if there isn't one at the position where we start the search. I'm not convinced with any of the ideas so I'm searching for some enlightening. Do you people have any better ideas?

  • General List of Common Programming Errors

    - by javamonkey79
    As one journey's from apprentice to journeyman to master I've noticed that one accumulates a list of best practices for things they've been bitten by. Personally, I write most of my stuff in java & SQL so my list tends to be slated towards them. I've accumulated the following: When doing list removal, always reverse iterate Avoid adding items to a list you are currently iterating on Watch out for NullPointerExceptions Now, I know there are language specific "common errors" links out there like this one. And I'm also aware of the pragmatic programmer tips, Martin Fowler's "code smells". Does anyone know of any good lists out there of things like I've listed above (re: list removal, adding items, etc). My guess is that there are some good QA folks out there that can probably throw me a bone here. I'm not looking for things the compiler can catch - I'm looking for common things that cause bugs. In the event that there isn't a list out there already then I welcome posting your own findings here. Thanks in advance!

  • Accessing second hard drive

    - by Jonathan
    So I recently installed Ubuntu 10.10 64-bit on my computer. I installed it on my 60gb SSD hard drive, and in the installation it never acknowledged the existence of my second hard drive. The hard drive that I keep all my files on, and which I want to make my home folder if I can, is a Western Digital Caviar Black 1TB SATA 6Gb/s 64MB cache (WD1002FAEX). I've read the following: https://help.ubuntu.com/community/Mount but honestly cannot work out how to access the hard drive from my Ubuntu installation. I did have Windows 7 64-bit prior to installing Ubuntu. I have backed up all the files on the hard drive, but if I could just access them straight off that would be super cool. Does anyone know how I can use the second hard drive? Thank you for your help EDIT: The following directories are currently in my /dev/ folder: ati/, block/, bsg/, bus/, char/, cpu/, isk/, input/, mapper/, net/, pktcdvd/, pts/, shm/, snd/, and usb/ EDIT: Result from sudo fdisk -l Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d2dfd Device Boot Start End Blocks Id System /dev/sda1 * 1 6994 56174592 83 Linux /dev/sda2 6994 7298 2438145 5 Extended /dev/sda5 6994 7298 2438144 82 Linux swap / Solaris @djeykib So very close to fixing it.. unfortunately on the last command you gave it says this: $ sudo apt-get install linux-lts-backport-natty Reading package lists...

  • No Obvious Answer - Query-Strings and Javascript

    - by nchaud
    Say I have this main page /my-site/all-my-bath-soaps which lists all my products. It has a search filter text box that uses javascript to filter the products they want to see on that page (the URL doesn't change as they filter). Now from many other parts of the site I want to navigate to this products-page and see specific products. E.g. <a href="/my-site/all-my-bath-soaps?filter='Nivea-Soap'"> will go to /all-my-bath-soaps and apply javascript filtering to see just that product and hide all dom nodes for the other products. The problem is if the user changes the text in the filter from 'Nivea-Soap' to 'Lynx' the javascript will work fine and show the new products but the URL stays at ?filter='Nivea-Soap'. Is there anything I can do about this? Of course, I don't want to reload the page with a new query string every time they change the search criteria. Somehow it'd be great to move the ?filter=... criteria into POST data instead - but how can I do this with a link I don't know...

  • What did Rich Hickey mean when he said, "All that specificity [of interfaces/classes/types] kills your reuse!"

    - by GlenPeterson
    In Rich Hickey's thought-provoking goto conference keynote "The Value of Values" at 29 minutes he's talking about the overhead of a language like Java and makes a statement like, "All those interfaces kill your reuse." What does he mean? Is that true? In my search for answers, I have run across: The Principle of Least Knowledge AKA The Law of Demeter which encourages airtight API interfaces. Wikipedia also lists some disadvantages. Kevlin Henney's Imperial Clothing Crisis which argues that use, not reuse is the appropriate goal. Jack Diederich's "Stop Writing Classes" talk which argues against over-engineering in general. Clearly, anything written badly enough will be useless. But how would the interface of a well-written API prevent that code from being used? There are examples throughout history of something made for one purpose being used more for something else. But in the software world, if you use something for a purpose it wasn't intended for, it usually breaks. I'm looking for one good example of a good interface preventing a legitimate but unintended use of some code. Does that exist? I can't picture it.

  • Dual-Boot Problem

    - by user171379
    I have a HP laptop that originally had Windows 7 OS on it, I partioned the drive and allocated 100gb (est.) for the ubuntu install. the install went fine i have ubuntu and windows 7 still on the computer. But I can not get the OS boot screen to show ubuntu as an OS. I can while start up pull up the start menu screen via ESC. Key and press F9 for Boot Device Options and get the boot manager screen and it lists... OS boot manager, Ubuntu (Hitachi HTS 543232A7A384), boot from EFI file, and Notebook Hard Drive... I can boot Ubuntu from this screen by selecting Ubuntu. But i would like to make it easier to access. The computer boot is not for myself otherwise it would not be a problem i would remove windows altogether. I would like to make it basically "User Friendly" if that's at all possible and make the OS boot screen show Ubuntu as a bootable OS as well as Windows 7. on the boot selection screen. Any help on this issue would be greatly appreciated, I've looked to see if i could find the answer and maybe i've overlooked something so here I am. Like i said i need it to be as user friendly as possible and force the user to choose windows 7 or ubuntu not send them into one or the other without them being allowed to choose. I can get any information you might need if necessary but i dont know exactly what you'll need other than what i've given. Ubuntu version is the 13.04 just so you know.

  • Floating point undesirable in highly critical code?

    - by Kirt Undercoffer
    Question 11 in the Software Quality section of "IEEE Computer Society Real-World Software Engineering Problems", Naveda, Seidman, lists fp computation as undesirable because "the accuracy of the computations cannot be guaranteed". This is in the context of computing acceleration for an emergency braking system for a high speed train. This thinking seems to be invoking possible errors in small differences between measurements of a moving object but small differences at slow speeds aren't a problem (or shouldn't be), small differences between two measurements at high speed are irrelevant - can there be a problem with small roundoff errors during deceleration for an emergency braking system? This problem has been observed with airplane braking systems resulting in hydroplaning but could this actually happen in the context of a high speed train? The concern about fp errors seems to not be well-founded in this context. Any insight? The fp is used for acceleration so perhaps the concern is inching over a speed limit? But fp should be just fine if they use a double in whatever implementation language. The actual problem in the text states: During the inspection of the code for the emergency braking system of a new high speed train (a highly critical, real-time application), the review team identifies several characteristics of the code. Which of these characteristics are generally viewed as undesirable? The code contains three recursive functions (well that one is obvious). The computation of acceleration uses floating point arithmetic. All other computations use integer arithmetic. The code contains one linked list that uses dynamic memory allocation (second obvious problem). All inputs are checked to determine that they are within expected bounds before they are used.

  • What is the program "Additional Drivers" (jockey-gtk) talking me about?

    - by Robert Vila
    The program says: "No proprietary drivers are in use on this system" But it doesn't say if it is talking about graphical drivers only or what. Then, it lists two drivers: NVIDIA accelerated graphics driver (version 173). NVIDIA accelerated graphics driver (version current) [recomended] Both have exactly the same description. What is the difference then? When I select the 1st one, it says: "This river is not activated",and there's a button to "activate" it. When I select the 2nd one, it says: "This river is activated but it is not currently in use", and the button is to "remove". So which one is in use? Why or what for should I have activated (enabled) and not in use? If it is in use it is activated? What is the difference between activate and remove? and what is the relationship between installed, activated, in use, enabled and removed, disabled, inactive and not-installed? Why can I activate the inactivated and remove (but not deactivate) the activated that is not in use? All this is very puzzling... What other drivers can I use for an Apple MacBook pro 3,1 and how? I see that there's a nouveau and I heard that there was going to be a new open source even better. > -display > description: VGA compatible controller > product: G84 [GeForce 8600M GT] > vendor: nVidia Corporation

  • OpenWeb(String) method

    - by ybbest
    I guess this is a SharePoint beginner problem ,however it took me a while to figure out what the problem is and I will blog it to help me to remember. Basically I wrote the following code to grab some list item from my SharePoint subsite http://win-oirj50igics/RestAPI,however I got the error stating that : “<nativehr>0×80070002</nativehr><nativestack></nativestack>There is no Web named / http://win-oirj50igics/RestAPI”. The problem is that OpenWeb(String) method returns the web site that is located at the specified server-relative or site-relative URL. It is the relative URL , so after I changed http://win-oirj50igics/RestAPI to RestAPI, everything works fine. using (SPSite site = new SPSite(http://win-oirj50igics/)) { SPWeb web = site.OpenWeb("http://win-oirj50igics/RestAPI"); SPQuery query = new SPQuery(); query.Query = camlDocument.InnerXml; SPListItemCollection items = web.Lists["Songs"].GetItems(query); IEnumerable<Song> sortedItems = from item in items.OfType<SPListItem>() orderby item.Title select new Song {SongName = item.Title, SongID = item.ID}; songs.AddRange(sortedItems); }

  • How can I learn more about ADF?

    - by jhpierce -Oracle
    Look to the Oracle Technology Network for a wealth of information, tutorials, best practices and coding examples. The place to start is the Oracle Application Development Framework (ADF) web page. The Oracle ADF page has basic information and downloads for ADF, but the real wealth is in the links to other pages. One of the pages is the Oracle ADF Code Corner,  which is a blog-style column that provides hints, tips and coding examples for ADF developers. The content on this page ranges from easy to complex and often contains advanced programming concepts. The content is inspired by questions asked on the Oracle JDeveloper customer forum on OTN. The ADF Code Corner has many articles that will inspire your imagination and possibly solve your coding problem.How about the Oracle ADF Architecture Square link? The Oracle ADF Architecture Square focuses on architectural issues and developer guidelines for writing ADF software solutions. The goal is to give ADF developers an understanding of the necessary decisions for building a successful ADF application, to offer potential architectural blueprints to choose from when putting the ADF application together, and to provide potential ADF best practices to take back to your development team. The Oracle ADF Mobile link gives information on developing mobile applications for iOS and Android based applications. There are links to ADF Mobile Overview, ADF Mobile demos and ADF Mobile courses.The Sample ADF Applications link lists sample applications and other resources where you can find code samples for ADF. These are complete ADF applications that can be downloaded into JDeveloper and give you insight into coding an application.There are many more links found under the "Learn More" tab that can equip the developer with the knowledge they need to develop their applications. There are links to overview papers, technical resources, related topics and available training. The information you need IS just a click away.

  • ifconfig can't see USB wireless

    - by Alex
    I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

  • How to represent a graph with multiple edges allowed between nodes and edges that can selectively disappear

    - by Pops
    I'm trying to figure out what sort of data structure to use for modeling some hypothetical, idealized network usage. In my scenario, a number of users who are hostile to each other are all trying to form networks of computers where all potential connections are known. The computers that one user needs to connect may not be the same as the ones another user needs to connect, though; user 1 might need to connect computers A, B and D while user 2 might need to connect computers B, C and E. Image generated with the help of NCTM Graph Creator I think the core of this is going to be an undirected cyclic graph, with nodes representing computers and edges representing Ethernet cables. However, due to the nature of the scenario, there are a few uncommon features that rule out adjacency lists and adjacency matrices (at least, without non-trivial modifications): edges can become restricted-use; that is, if one user acquires a given network connection, no other user may use that connection in the example, the green user cannot possibly connect to computer A, but the red user has connected B to E despite not having a direct link between them in some cases, a given pair of nodes will be connected by more than one edge in the example, there are two independent cables running from D to E, so the green and blue users were both able to connect those machines directly; however, red can no longer make such a connection if two computers are connected by more than one cable, each user may own no more than one of those cables I'll need to do several operations on this graph, such as: determining whether any particular pair of computers is connected for a given user identifying the optimal path for a given user to connect target computers identifying the highest-latency computer connection for a given user (i.e. longest path without branching) My first thought was to simply create a collection of all of the edges, but that's terrible for searching. The best thing I can think to do now is to modify an adjacency list so that each item in the list contains not only the edge length but also its cost and current owner. Is this a sensible approach? Assuming space is not a concern, would it be reasonable to create multiple copies of the graph (one for each user) rather than a single graph?

  • Fault Handling Slides and Q&A by Vennester

    - by JuergenKress
    Fault Handling It is one thing to architect, design, and code the “happy flow” of your automated business processes and services. It is another thing to deal with situations you do not want or expect to occur in your processes and services. This session dives into fault handling in Oracle Service Bus 11g and Oracle SOA Suite 11g, based on an order-to-cash business process. Faults can be divided into business faults, technical faults, programming errors, and faulty user input. Each type of fault needs a different approach to prevent them from occurring or to deal with them. For example, apply User Experience (UX) techniques to improve the quality of your application so that faulty user input can be prevented as much as possible. This session shows and demos what patterns and techniques can be used in Oracle Service Bus and Oracle SOA Suite to prevent and handle technical faults as well as business faults. Q&A This section lists answers to the questions that were raised during the preview event. Q: Where can retries be configured in Oracle Service Bus? The retry mechanism is used to prevent faults caused by temporary glitches such as short network interruptions. A faulted message is resend (retried) and might succeed this time since the glitch has passed. Retries are an out-of-the-box feature that can be used in Oracle Service Bus and Oracle SOA Suite using the Fault Policy framework. By default, retries are disabled in Oracle Service Bus.

  • Error while installing an application

    - by Bong.Da.City
    So i have installed synaptic package manager.. via it, i have checked once libopencv-highgui-dev and applied complete removal.. after that i installed it... now everytime i try to install an application e.g Format Junkie sudo add-apt-repository ppa:format-junkie-team/release && sudo apt-get update && sudo apt-get install formatjunkie in the command install format junkie it gives me that error everytime: sudo apt-get install formatjunkie Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libopencv-features2d-dev : Depends: libopencv-highgui-dev (= 2.3.1-11ubuntu2) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. What should i do? And 2nd what did i did wrong so it won't happen another time? output of lsb_release -a No LSB modules are available.

  • Pros and cons of PHP vs C,C++ as language in a programming interview ?

    - by DhruvPathak
    Hi All, Though this is a matter of personal choice and comfort. I would want your views on a situation like this. Programmer A has been working on PHP for some years, and has had prior experience in C.C++ during algorithm courses in university. The current fluency is good is PHP,but C,C++ can also be brushed up. So for interviews with major companies who put lot of emphasis on algorithms and data structures in programming interview e.g. binary trees, linked lists, arrays , strings . What should programmer A do ? Try to implement those things in PHP ( which is generally more suited for web development rather than programming contests/interviews ) or Or brush up the C,C++ skills and keep them as primary tool for tackling interview questions. What are advantages/ disadvantages of each language for an environment like programming contest or an interview ? Why would you recommend,not recommend Programmer A to participate in a contest like google code Jam/ ACM ICPC using PHP instead of C++ ? ( assuming PHP is allowed as a language there)

  • Package manager doesn't work anymore

    - by LukaD
    I'm using ubuntu 10.10 and recently my package manager has stopped working because of some problems with dependencies or something. I can't upgrade, install or uninstall anything at all. This is a huge problem. I couldn't find a solution to this with google so I'm asking here for help.

  • Need efficient way to keep enemy from getting hit multiple times by same source

    - by TenFour04
    My game's a simple 2D one, but this probably applies to many types of scenarios. Suppose my player has a sword, or a gun that shoots a projectile that can pass through and hit multiple enemies. While the sword is swinging, there is a duration where I am checking for the sword making contact with any enemy on every frame. But once an enemy is hit by that sword, I don't want him to continue getting hit over and over as the sword follows through. (I do want the sword to continue checking whether it is hitting other enemies.) I've thought of a couple different approaches (below), but they don't seem like good ones to me. I'm looking for a way that doesn't force cross-referencing (I don't want the enemy to have to send a message back to the sword/projectile). And I'd like to avoid generating/resetting multiple array lists with every attack. Each time the sword swings it generates a unique id (maybe by just incrementing a global static long). Every enemy keeps a list of id's of swipes or projectiles that have already hit them, so the enemy knows not to get hurt by something multiple times. Downside is that every enemy may have a big list to compare to. So projectiles and sword swipes would have to broadcast their end-of-life to all enemies and cause a search and remove on every enemy's array list. Seems kind of slow. Each sword swipe or projectile keeps its own list of enemies that it has already hit so it knows not to apply damage. Downsides: Have to generate a new list (probably pull from a pool and clear one) every time a sword is swung or a projectile shot. Also, this breaks down modularity, because now the sword has to send a message to the enemy, and the enemy has to send a message back to the sword. Seems to me that two-way streets like this are a great way to create very difficult-to-find bugs.

  • Tail-recursive implementation of take-while

    - by Giorgio
    I am trying to write a tail-recursive implementation of the function take-while in Scheme (but this exercise can be done in another language as well). My first attempt was (define (take-while p xs) (if (or (null? xs) (not (p (car xs)))) '() (cons (car xs) (take-while p (cdr xs))))) which works correctly but is not tail-recursive. My next attempt was (define (take-while-tr p xs) (let loop ((acc '()) (ys xs)) (if (or (null? ys) (not (p (car ys)))) (reverse acc) (loop (cons (car ys) acc) (cdr ys))))) which is tail recursive but needs a call to reverse as a last step in order to return the result list in the proper order. I cannot come up with a solution that is tail-recursive, does not use reverse, only uses lists as data structure (using a functional data structure like a Haskell's sequence which allows to append elements is not an option), has complexity linear in the size of the prefix, or at least does not have quadratic complexity (thanks to delnan for pointing this out). Is there an alternative solution satisfying all the properties above? My intuition tells me that it is impossible to accumulate the prefix of a list in a tail-recursive fashion while maintaining the original order between the elements (i.e. without the need of using reverse to adjust the result) but I am not able to prove this. Note The solution using reverse satisfies conditions 1, 3, 4.
