  • C# Winform : Deployment Problem after using DataRepeater of MS Visual Bacis power pack

    - by Mohsan
    hi. Microsoft Visual Studio 2008 Service pack 1 comes with Visual Basic Powerpacks which has the DataRepeater control. I used this control in my c# winform application. in my system everything is running fine. now i copied the debug folder to other system which has only .Net Framework 3.5 SP1 installed. in this system is giving me error cannot load dependency Microsoft.VisualBasic.PowerPacks.dll even i set the Copy Local to "true" for "Microsoft.VisualBasic.dll" and "Microsoft.VisualBasic.PowerPacks.Vs.dll" please tell me how to solve this problem

  • error handeling in informatca power center

    - by user223541
    i want to devlop a mapping for followinfg scenerio . I have a 1 source and 1 target and 1 error table.Target and Error tables have all fields that are present in source tables.But the data type o of all fieds for error table are varchar .Error table dont have integirty or foreign key and other constraints . Error table also have2 more fileds .Error no and error msg. Now when the workflow is executed if there is erro while inserting any record then that recored shold be moved to error table.Also the data base error code and error message should be logged in error no and error message in error tables fields as mentioned. How can i devlop such a mappng?Where can i find exaples of such mapping ?

  • Using different SSDs types (not only SATA based) as system drive

    - by Hubert Kario
    Currently I have a Thinkpad X61s and want to make it both a bit faster and a bit more power efficient. For that reason I thought that adding SSD drive would make most sense. Unfortunately, because of financial reasons, buying SSD of over 200GB capacity is out of reach for me (not only it would be worth more than the rest of the laptop, but also I currently have a 500GB drive in it, so even such a drive would be kind of a downgrade for me). During preliminary testing with a cheap Transcend 4GB Class 6 (14MiB/s streaming, 9MiB/s random read) card I experienced boot times to be reduced by half so putting the OS only on it would already would be an improvement. Unfortunately, my system now is about 11GiB in size so anything less than 16GB would be constraining. In this laptop I can connect additional drives on at least 5 different ways: using SATA-ATA converter caddy in the X6 Ultrabase using internal mini PCIe slot using integrated SDHC slot using CardBus (a.k.a PCMCIA or PC Card) slot using USB Thankfully, because I use only Linux on this PC the bootability of them is irrelevant as I can put the /boot partition on internal HDD and / on any of the above mentioned Flash memories (as I already did for the SDHC test). From what I was able to research and from my own experience those options come with rather big downsides or other problems: SATA-ATA caddy It has three downsides: I have to carry the Ultrabse with me at all times (it's not really inconvenient, but those grams do add) and couldn't disconnect it when I want to disconnect the battery It makes the bay unusable for the optical drive and occasional quick access to other hard drives the only caddies I could buy have rather flaky controllers in them so putting my OS on it would hamper its stability Internal mini PCIe slot This would be an ideal solution, if only I could find real PCIe SSDs, not only devices that could talk only SATA or ATA over PCIe mechanical connection (the ones used in Dell Mini or Asus EEE). Theoretically Samsung did release such devices but I couldn't find them in retail anywhere. Integrated SDHC slot It's a nice solution with a single drawback: the fastest 16GB SDHC card on the market can only do around 35MiB/s read and 15MiB/s write while still costing like a normal 40GB SATA SSD that's 10 times faster. Not really cost-effective. CardBus (a.k.a PCMCIA or PC Card) slot Those cards are much faster than the SDHC option (there are ones that can do well over 50MiB/s read in benchmarks) and from what I could find the PCMCIA controller in my laptop does support UDMA so it should be able to deliver comparable speeds. They still cost similarly to SD cards but at least they provide streaming performance comparable to my current HDD. USB That's the worst option. Not only is it limited to 20-30MiB/s by the interface itself the drive would stick out of the laptop so it's a big no no. The question As such I think that going the "CF in a CardBus adapter" route will be the best option. My question is: did anyone try using CF cards in CardBus adapters as system drives with Linux on Thinkpad laptops? Laptops in general? What was the real-world performance? I don't have any CF cards so I can't check how well does it work with suspend/resume, or whatever it's easy to make it work in initramfs (I'm using ArchLinux and SD card was trivial — add 3 modules in single config line and rebuilding initramfs) so any tips/gotchas on this are welcome as well.

  • Facebook Hacker Cup: Power Overwhelming

    - by marcog
    A lot of people at Facebook like to play Starcraft II™. Some of them have made a custom game using the Starcraft II™ map editor. In this game, you play as the noble Protoss defending your adopted homeworld of Shakuras from a massive Zerg army. You must do as much damage to the Zerg as possible before getting overwhelmed. You can only build two types of units, shield generators and warriors. Shield generators do no damage, but your army survives for one second per shield generator that you build. Warriors do one damage every second. Your army is instantly overrun after your shield generators expire. How many shield generators and how many warriors should you build to inflict the maximum amount of damage on the Zerg before your army is overrun? Because the Protoss value bravery, if there is more than one solution you should return the one that uses the most warriors. Constraints 1 = G (cost for one shield generator) = 100 1 = W (cost for one warrior) = 100 G + W = M (available funds) = 1000000000000 (1012)

  • Whats the most common waste of computing power in javascipt

    - by qwertymk
    We've all seen people who do this jQuery('a').each(function(){ jQuery(this)[0].innerHTML += ' proccessed'; }); function letsPoluteNS() { polute = ''; for (morePolution = 0; morePolution < arguments.length; morePolution++) polute.join(arguments[morePolution]); return polute; } and so on. I was wondering what people have seen the most common javascript/jQuery technique that is slowing down the page and/or wasting time for the javascript engine. PS I know that this question may not seem to fit into whats an accepted question, yet I'm asking for what the most common accepted waste is

  • What power do I have over my license?

    - by DavidG
    Say for example, I've written some code under GPL 3. My company wants to use that code for a commercial product. Am I allowed to then say to them that they can use it under LGPL/MIT or any other license? If so, would I then have to change the included header at the top of each file? If so, what is stopping someone else from changing the license on my code?

  • Step by Step / Deep explain: The Power of (Co)Yoneda (preferably in scala) through Coroutines

    - by Mzk
    some background code /** FunctorStr: ? F[-]. (? A B. (A -> B) -> F[A] -> F[B]) */ trait FunctorStr[F[_]] { self => def map[A, B](f: A => B): F[A] => F[B] } trait Yoneda[F[_], A] { yo => def apply[B](f: A => B): F[B] def run: F[A] = yo(x => x) def map[B](f: A => B): Yoneda[F, B] = new Yoneda[F, B] { def apply[X](g: B => X) = yo(f andThen g) } } object Yoneda { implicit def yonedafunctor[F[_]]: FunctorStr[({ type l[x] = Yoneda[F, x] })#l] = new FunctorStr[({ type l[x] = Yoneda[F, x] })#l] { def map[A, B](f: A => B): Yoneda[F, A] => Yoneda[F, B] = _ map f } def apply[F[_]: FunctorStr, X](x: F[X]): Yoneda[F, X] = new Yoneda[F, X] { def apply[Y](f: X => Y) = Functor[F].map(f) apply x } } trait Coyoneda[F[_], A] { co => type I def fi: F[I] def k: I => A final def map[B](f: A => B): Coyoneda.Aux[F, B, I] = Coyoneda(fi)(f compose k) } object Coyoneda { type Aux[F[_], A, B] = Coyoneda[F, A] { type I = B } def apply[F[_], B, A](x: F[B])(f: B => A): Aux[F, A, B] = new Coyoneda[F, A] { type I = B val fi = x val k = f } implicit def coyonedaFunctor[F[_]]: FunctorStr[({ type l[x] = Coyoneda[F, x] })#l] = new CoyonedaFunctor[F] {} trait CoyonedaFunctor[F[_]] extends FunctorStr[({type l[x] = Coyoneda[F, x]})#l] { override def map[A, B](f: A => B): Coyoneda[F, A] => Coyoneda[F, B] = x => apply(x.fi)(f compose x.k) } def liftCoyoneda[T[_], A](x: T[A]): Coyoneda[T, A] = apply(x)(a => a) } Now I thought I understood yoneda and coyoneda a bit just from the types – i.e. that they quantify / abstract over map fixed in some type constructor F and some type a, to any type B returning F[B] or (Co)Yoneda[F, B]. Thus providing map fusion for free (? is this kind of like a cut rule for map ?). But I see that Coyoneda is a functor for any type constructor F regardless of F being a Functor, and that I don't fully grasp. Now I'm in a situation where I'm trying to define a Coroutine type, (I'm looking at https://www.fpcomplete.com/school/to-infinity-and-beyond/pick-of-the-week/coroutines-for-streaming/part-2-coroutines for the types to get started with) case class Coroutine[S[_], M[_], R](resume: M[CoroutineState[S, M, R]]) sealed trait CoroutineState[S[_], M[_], R] object CoroutineState { case class Run[S[_], M[_], R](x: S[Coroutine[S, M, R]]) extends CoroutineState[S, M, R] case class Done[R](x: R) extends CoroutineState[Nothing, Nothing, R] class CoroutineStateFunctor[S[_], M[_]](F: FunctorStr[S]) extends FunctorStr[({ type l[x] = CoroutineState[S, M, x]})#l] { override def map[A, B](f : A => B) : CoroutineState[S, M, A] => CoroutineState[S, M, B] = { ??? } } } and I think that if I understood Coyoneda better I could leverage it to make S & M type constructors functors way easy, plus I see Coyoneda potentially playing a role in defining recursion schemes as the functor requirement is pervasive. So how could I use coyoneda to make type constructors functors like for example coroutine state? or something like a Pause functor ?

  • Article about code density as a measure of programming language power

    - by prosseek
    I remember reading an article saying something like "The number of bugs introduced doesn't vary much with different programming languages, but it depends pretty much on SLOC (source lines of code). So, using the programming language that can implement the same functions with smaller SLOC is preferable in terms of stability." The author wanted to stress the advantages of using Functional Programming, as normally one can program with a smaller number of LOC. I remember the author cited a research paper about the irrelevance of choice of programming language and the number of bugs. Is there anyone who knows the research paper or the article?

  • Why PC reboots when there’s a power failure even with UPS?

    - by Jamil
    I've purchased a Line Interactive UPS 1200VA. It's supposed to give 8~20min backup (as written in the manual). This UPS has transfer time < 10ms. It works fine when the mains is active. But the problem is that when the power went off, the PC also went off for a fraction of a second and started rebooting. The strangest thing though is that it has to be a proper power failure by the service supplier. If I just turn off the power at the wall plug, the UPS kicks in immediately and the PC carries on working fine. What's the solution of that? What should I do? My hard drive was physically damaged because of improper shut down & restart. I've 5~8 times power outage in my country so I badly need an UPS.

  • UPS: Do i require a special extension cord for power in?

    - by rism
    I have a couple of Tripplite UPS systems. The power in cables are bright orange and about 2 meters in length. I want to put the system on the other side of the room but for some reason the UPS keep "going off" over there. So I guess the wall power sockets on that side of the room are a little dodgy. So i figured Id just go online and get some replacement UPS power IN (from wall to UPS) cables of an appropriate length. But i cant find any anywhere. (auction sites, tripplite store, cable websites). So now I'm wondering if that's just because you can use a standard extension cord of an appropriate wattage? I thought the UPS power IN cables were "special". Is that not so?

  • VMware Workstation "Power off" and "Suspend" buttons are disabled. What is going on?

    - by Ed Norris
    I've been using an XP image for a few months now with no problems. Recently the power off and resume buttons were disabled and I'm not sure what happened to cause that. In addition, the menu items to do those functions are grayed out (like VM | Power | Power Off) I'm using VMware Workstation 6.5.3 on a Windows 7 64-bit host. The image is Windows XP 32-bit. There is plenty of free space and memory on the host and the CPU is not pegged. I am able to power off the image through its Start menu, but that's a workaround not a fix. Any suggestions? TIA EDIT: Well after manually shutting down the image then closing and reopening the image file (which I've done before) in preparation for reinstalling the tools as suggested below, it looks fine. The power off and suspend buttons are enabled and work. So what do I do with this question now? "Close and restart a few times and it may work" doesn't seem useful...

  • Can a motherboard be faulty even if it's getting power and so are components hooked up to it?

    - by Davy8
    Sort of a followup to this question. The mobo's getting power, the lights are on. The GPU fan is spinning (it doesn't use auxiliary power, it's only connected to the mobo). I'm not getting any video signal, and it's not the video card (nor monitor) that's faulty, so I'm suspecting mobo or CPU (possibly RAM?) and I'm trying to pinpoint which part is at fault. Is the motherboard a candidate for being broken or is it not very likely if it's getting power and powering other components? The CPU fan is getting power as well.

  • Can I use stronger power supply to charge Kindle? [closed]

    - by Bobb
    I have power supply for Kindle with output 5V 0.85A. And I have Samsung Galaxy Pad one with output of 5V 2A. My guess is that a device will consume as much current as it can but no more than max power supply current. For example if Kindle device consumes 0.6A for charging its battery then it shouldnt create more than 0.6A current using Galaxy Pad power supply. So my guess - if I charge Kindle with Galaxy Pad power supply it wont burn out. Is that right?

  • How to reduce memory consumption an AWS EC2 t1.micro instance (free tier) ubuntu server 14.04 LTS EBS

    - by CMPSoares
    Hi I'm working on my bachelor thesis and for that I need to host a node.js web application on AWS, in order to avoid costs I'm using a t1.micro instance with 30GB disk space (from what I know it's the maximum I get in the free tier) which is barely used. But instead I have problems with memory consumption, it's using all of it. I tried the approach of creating a virtual swap area as mentioned at Why don't EC2 ubuntu images have swap? with these commands: sudo dd if=/dev/zero of=/var/swapfile bs=1M count=2048 && sudo chmod 600 /var/swapfile && sudo mkswap /var/swapfile && echo /var/swapfile none swap defaults 0 0 | sudo tee -a /etc/fstab && sudo swapon -a But this swap area isn't used somehow. Is something missing in this approach or is there another process of reducing the memory consumption in these type of AWS instances? Bottom-line: This originates server freezes and crashes and that's what I want to stop either by using the swap, reducing memory usage or both.

  • What is the justification for Python's power operator associating to the right?

    - by Pieter Müller
    I am writing code to parse mathematical expression strings, and noticed that the order in which chained power operators are evaluated in Python differs from the order in Excel. From http://docs.python.org/reference/expressions.html: "Thus, in an unparenthesized sequence of power and unary operators, the operators are evaluated from right to left (this does not constrain the evaluation order for the operands): -1*2 results in -1."* This means that, in Python: 2**2**3 is evaluated as 2**(2**3) = 2**8 = 256 In Excel, it works the other way around: 2^2^3 is evaluated as (2^2)^3 = 4^3 = 64 I now have to choose an implementation for my own parser. The Excel order is easier to implement, as it mirrors the evaluation order of multiplication. I asked some people around the office what their gut feel was for the evaluation of 2^2^3 and got mixed responses. Does anybody know of any good reasons or conciderations in favour of the Python implementation? And if you don't have an answer, please comment with the result you get from gut feel - 64 or 256?

  • AHCI, Power Mode S3 and HPET 64bit - please help with these settings!

    - by thetattoo
    my problem is the that for a Hackintosh (unofficial PC running OS X) I needed to set AHCI, Power Mode S3 and HPET 64bit. Now, I want to install Ubuntu (when 12.04 comes out) and was wondering if these settings will be right to use for Ubuntu. I read that AHCI is how the hard disks are accessed, Power Mode S3 is how suspend works with the RAM but couldn't figure out if using HPET 64bit makes any difference than HPET 32bit. What I would like is an explanation of what these BIOS settings do and what is best for Ubuntu. Thank you very much

  • Cant access Dell BMC IPMI Over IP

    - by Bobb
    I have Dell R210 with iDRAC BMC (new name for old BMC). Which is on-board feature with shared NIC (I believe). Server is on colocation and I didnt set it up before sent there... So I asked for the remote hands to setup IPMI Over IP. They enabled it, set the IP and everything. The IP is different than main box IP. Also the box is cabled to NIC1 and the BMC supposed to share it (am I right?) I can see new IP in the Open Server Administrator (installed on the box). I tried Supermicro IPMI tool and I tried Dell ipmish.exe command like this ipmish -ip xxx -u root -p calvin sysinfo gives BMC is not detected What could be wrong? is there a diagnostics tool I can try? It must be something obvious. I just never used things like that before.... P.S. I read something about encryptions key in the Dell docs. But I understand that is for encrypted IPMI 2.0 and ipmish can use IPMI 1.5 without encryption.

  • Dell PSU Compatibility: Dell Inspiron 530 (Desktop)

    - by ashes999
    I have an Inspiron 530 with a stock PSU. I need to upgrade it to meet my video card's needs (AMD HD6770), which demands at least 450W, to potentially fix BSODs with the latest version of the drivers (so claims AMD support). Now, I've heard conflicting reports about whether Dell uses special/proprietary PSUs. (Examples for aye and nay to special PSUs.) How exactly can I determine if a PSU is compatible with my PC, before buying it? I assume I will not be able to return it if it doesn't fit, or makes my computer explode in a fireball of doom.

  • What are good values for PSU voltages?

    - by earlz
    Hello, I have an odd computer I'm trying to fix that will crash only during the setup of an OS(crashes on every OS I've tried so far) It's not overheating and it is stripped down as much as possible and I've tried multiple harddrives, and memtest86+ can run on it for 3 hours without a crash or fail. So, I was a bit stumped and was looking in the BIOS for possible causes and found a hardware monitor that shows PSU voltages. They are: VCORE: 1.432V 3.3V: 3.136V 5V: 5.273 12V: 12.144V I thought the 3.3V looked a little low, but I'm not really sure on how "bad" that is. So, what are the good ranges for the voltages on each CPU rail?

  • Macbook Pro with Windows 7 - GPU always on

    - by Joonas Pulakka
    Übergizmo is reporting an issue with the new Macbook Pros' GeForce 330M GPU being always "on" under Windows 7, and thus almost halving the battery life compared to that with OS X (which is able to somehow suspend that GPU and use the the low-end integrated GPU to do the light work). Any solutions, or rumors of coming solutions?
