  • LASER x Deskjet Printer

    - by Mike
    I am about to buy a color printer. I had a b&W laserjet printer in the past but since then I use deskjet for decades. I need a printer that can deliver high quality as these photo deskjet printers but I am tired of paying ink that costs $9,000 per gallon of ink (1 gallon = 3.785 liters = 300 cartridges = $9,000). So, I was pondering about buying a color laser, but I am not sure if these printers can deliver the same quality and worth the investment in terms of toner consumption. I remembered that my old laserjet printer was able to print 1100 pages per toner cartridge. The deskjet printers I have can print 500 pages per cartridge. Price by price, 2 deskjet cartridges have more or less the same cost as one toner cartridge and in theory prints almost the same. I am not sure if this is true for color lasers. What you guys can tell me about quality, toner cost and cost per page using laser or deskjet. Does it worths the change? Remember that a deskjet printer costs $50 and a laser printer costs $200. thanks.

  • Why is Haskell used so little in the industry?

    - by bugspy.net
    It is a wonderful, very fast, mature and complete language. It exists for a very long time and has a big set of libraries. Yet, it appears not to be widely used. Why ? I suspect it is because it is pretty rough and unforgiving for beginners, and maybe because its lazy execution makes it even harder

  • SQL Server high CPU and I/O activity database tuning

    - by zapping
    Our application tends to be running very slow recently. On debugging and tracing found out that the process is showing high cpu cycles and SQL Server shows high I/O activity. Can you please guide as to how it can be optimised? The application is now about an year old and the database file sizes are not very big or anything. The database is set to auto shrink. Its running on win2003, SQL Server 2005 and the application is a web application coded in c# i.e vs2005

  • ASP.NET MVC, MVVM and file uploads...

    - by Kieron
    Hi, I'm big fan of the MVVM pattern, in particular while using the ASP.NET MVC Framework (in this case v2 preview 2). But I'm curious if anyone knows how to use it when doing file uploads? public class MyViewModel { public WhatTypeShouldThisBe MyFileUpload { get; set; } }

  • Embed .swf in webpage and make it fullscreen

    - by Farinha
    Is there a way to embed a .swf file in a webpage and provide a way to make it fullscreen? I'm creating these files with Adobe Captivate, which doesn't seem to provide a way to publish in other usable formats (.avi files are too big, and no .flv is available, to which there seem to have some players around that allow fullscreen). If there's a way to convert .swf to some other "embedable" format, please let me know.

  • Tomcat performing terribly for no apparent reason

    - by John
    We're running a game application .WAR on Tomcat 6 on an Amazon EC2 server, 8 core processor, 7gb RAM. The application uses a MySQL database hosted on Amazon RDS. This Facebook application takes ages to access when a mere 20-30 users are playing it. Big difference from 1-2 users. The entire .WAR is ~4mb, all static content hosted elsewhere. The server has never been close to running out of RAM. The CPU utilization has never been higher than 13.5-14%. Even with ~500 users that completely slowed everything to a standstill. The thread count or threadpools isn't close to being maxed out. I heightened maxthreads but it didn't make a noticeable difference. My theory is that Tomcat can only use one processor core, which would explain why it was slowed to a halt even though CPU usage was stably at 13-14% at the activity spike. But I'm struggling to understand why it would only use one CPU core. There is no processor cap in server.xml. The app contains several servlets (4 or 5). There is no mention of SingleThreadModel in the Java code. WHAT could be causing the application to run extremely slowly? If there is only 1-5 people on the application it runs fine. With 20-30 people it's barely contactable.

  • Hotkey for double-click highlight?

    - by Steven Wright
    I'm working in Eclipse and find myself always replacing multiple copies of the same word, but I always have to take my hands off the keyboard and screen to get the mouse, hover over the word, double click to select, and then copy or rewrite the word. Is there any way I can just move the cursor inside the word and hit some hotkey that would highlight it? Seems like this would be a big timesaver. Or if there's a way to create a hotkey that would be perfect too.

  • How do I get "Back to My Mac" (using MobileMe) from Windows?

    - by benzado
    I have a MobileMe subscription and a Mac at home with "Back to My Mac" enabled. When I'm away from home, this service lets me use another Mac to connect to my Mac back home and access file sharing, screen sharing, etc. As far as I know, the service doesn't use any proprietary protocols, so in theory I should also be able to get "Back to My Mac" from a Windows PC. This MacWorld article explains how it works. Basically, it uses Wide-Area Bonjour to give your Mac a domain name like hostname.username.members.mac.com. Remote computers can find your Mac using that address, then connect to it using a private VPN. The "Wide Area Bonjour" part seems to make it a little more complicated than simply a regular domain name, though. Note that I'm not interested in using the methods described by LifeHacker, which doesn't use the MobileMe service at all. I don't want to use a totally different dynamic DNS service. I'd like to use the one I'm already paying for, or at least find out why that's not possible from Windows. Also, my primary problem is finding a network route back to my mac... once I've got that I know how to enable services so that Windows can talk to it. UPDATE: Based on some additional research, it appears that Apple is only assigning IPv6 addresses to the hostname.username.members.mac.com names. So any solution will require enabling IPv6 support on Windows, if possible.

  • php socket servers, actionscript 3 and multiplayer

    - by numerical25
    So I am thinking about creating a multiplayer game and I was wanting to use php because I already have a php server. Is it possible to make a socket server that will be able to handle a actionscript multiplayer game. The game won't be big. so we wont need any huge amount of data pushing through. just some software that is probably reliable enough to run a multiplayer game.

  • VPN being blocked somewhere between either my BT2700HGV and DLink DFL-210

    - by Dom
    Hi, For some time I have been unable to get VPN working through my set up. I have a BT2700HGV Router (2 Wire Model) and as a firewall I have the Dlink DFL-210. You can't turn the firewall completely off on the BT2700HGV so I have it set to DMZplus mode for the Firewall. In theory this should then allow the VPN ports through. On the Firewall I have a series of rules set up and one is the pptp-allow rule which should allow access on the correct ports also. When I try to connect via VPN however the client machine gets an error 809. If I check the log on the Dlink firewall, I see this record: http://dl.dropbox.com/u/1041315/packetdrop.PNG The laptop I am testing the vpn with is connected directly to the BT2700HGV router and I am trying to VPN from it onto 81.138.86.217. I can't work out whether I have some sort of problem in the set up of the rules on my firewall or if the BT router (even though it's in DMZplus mode) is still blocking port 1723. I read somewhere that there where problems because BTs Openzone held onto this port for some reason. Any help would be greatly appreciated. If you need further screen shots or information then please let me know. I wasn't able to create new tags for the router and firewall name or insert the picture in as I am new to the forum. Dom :-)

  • Is currying just a way to avoid inheritance?

    - by Alex Mcp
    So my understanding of currying (based on SO questions) is that it lets you partially set parameters of a function and return a "truncated" function as a result. If you have a big hairy function takes 10 parameters and looks like function (location, type, gender, jumpShot%, SSN, vegetarian, salary) { //weird stuff } and you want a "subset" function that will let you deal with presets for all but the jumpShot%, shouldn't you just break out a class that inherits from the original function? I suppose what I'm looking for is a use case for this pattern. Thanks!

  • How to create VHD disk image from a Linux live system?

    - by Federico
    Once more, I have to resort at the experts here at SuperUser, as my other sources (mainly Google ;-)) didn't prove very helpful... So basically, I would like to create a VHD image of a physical disk to be archived/accessed/maybe even mounted in a virtual machine. Now, there are dozens of articles and tutorials on how to do that on the web, but none that meets exactly the conditions I would like to achieve: I would like the destination file to be a VHD image, as Windows 7 can mount it natively, even over the network and many other programs can use it (VirtualBox, ...) The disk I'm trying to image contains a Windows XP install, so in theory, I could use the disk2vhd utility, but I would like to find a solution that doesn't require booting that Windows XP install (ie keep the disk read-only) Thus I was searching for a solution involving some sort of live system (running from a USB stic or the network) However, all the solutions that I've came across either make use of disk2vhd or use the dd command under linux, which does a complete copy of the disk (ie even empty blocks) and does not output a VHD file. Is there a tool/program under Linux that can directly create a VHD file? Or is is possible to convert a raw disk image created using dd to a VHD file, without allocating space for the empty blocks? How would you proceed? As always, any advice or comment is highly appreciated!!

    Which paradigm is better for design and analysis of algorithms? Which is faster? Because I have a subject called Design and Analysis of Algorithms in university and have a time limit for programs. Is OOP slower than Procedure programming? Or the time difference is not big?

  • Any software to auto generate doxygen comment blocks?

    - by Simone Margaritelli
    Hello, i'm developing a quite big C++ software and now (better late than neve :)) i've decided to document it in the doxy standards. There are plenty of classes, methods, functions, macros and so on therefore i'm searching for a software that would scan my source tree and insert doxy comment blocks on top of every "documentable item" to let me edit them later and add details such as methods description and so on. Some hint?

  • What would cause my Silverlight .xap to quadruple in size suddenly?

    - by Edward Tanguay
    I've been working on a Silverlight application. I just noticed that the .xap file is now four times as big as it was, what could have caused that? Here's some other info: there seems to now be many more language settings in the bin/Release directory I checked "Reduce size of .xap" in under Properties/Silverlight but that just brought it down from 1300 to 1200. I reference the System.Windows.Controls.Toolkit dll but I was doing that even when it was 325K Screenshot of build directories before and after:

  • Tips for transitioning from Visual Basic to Xcode

    - by Cyclone
    I've been programming in VB.net for a while now, and I finally got access to a mac to make ipod apps. What are some useful sites, videos, etc. that could help me get used to Objective C and the Xcode IDE? I've stumbled upon the samples on the apple dev site, but none of them really give good examples which I could learn the syntax of the language from. Thanks for the help, Objective C is really a big change from VB.net!
