  • What's the (memory) footprint of a J2EE servlet?

    - by Amr Mostafa
    For Jetty, Tomcat, or any other servlet container of your choice, what's the average footprint (memory, and any other notable resources) of a basic servlet? This includes any other basic objects that you almost always need per servlet, such as a view resolver. I'm not looking for a quantitative number in particular, but any indicative answer that could give an idea of how "heavy" or "lightweight" a servlet is. Thanks in advance

  • Useful Vim features

    - by Craig H
    Vim is my editor of choice, and I feel I am above average in my use of it. I do recognize, though, that the feature list of vim is huge. With this in mind, I was wondering what features you vim users out there use on a regular basis.

    - by HardCoder1986
    Hello! I have some code which shows a simple dialog box and handles user action (written using plain WinAPI). // Display dialog and handle user action LRESULT choice = DialogBoxParam(NULL, MAKEINTRESOURCE(AP_IDD_DIALOG), NULL, (DLGPROC)DialogCallback, NULL); Is there any way to hardcode the resource file dialog.rc, which is used to build the dialog ?(I would like to get rid of .rc files and I'm pretty sure there is a way, yet I don't know what it is :)

  • How can i optimize this python code

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • Confusing If Statement?

    - by NetSide
    I always use If statement (In C#) as (1. Alternative); if (IsSuccessed == true) { // } I know that there is no need to write "== true" as (2. Alternative)); if (IsSuccessed) { // } But, I use it because it is more readable and cause no performance issue. Of course, this is my choice and I know many software developers prefer first alternative. What is the best usage, and Why?

  • There's @interface in my @implementation — why is that?

    - by Mark McDonald
    This is a pretty noobish question – I'm looking at some Cocoa sample code and there's @interface blocks in the .m files as well as the headers. For instance, in the AppDelegate class header, a UIWindow and UI navigation are defined as instance variables, but the @property declarations are actually made in the implementation file. Is there a functional reason for this, is it a stylistic choice, or… ?

  • How do I write an MVC 1 app with MVC 2?

    - by SLC
    I went to http://www.asp.net/mvc and the web installer offered me the option to install MVC 2, but not MVC 1. I thought MVC 2 was still in beta? Either way, I need to write an MVC 1 app. In visual studio, my only choice is either ASP.NET Web Application or ASP.NET MVC 2 Web Application. Can anyone advise?

  • XML XQUERY Problem with NTEXT data type

    - by johnfa
    Hello I want to use XQuery on a column of data type NTEXT (I have no choice!). I have tried converting the column to XML using CONVERT but it gives the error: Incorrect syntax near the keyword 'CONVERT'. Here's the query SELECT y.item.value('@UserID', 'varchar(50)') AS UnitID, y.item.value('@ListingID', 'varchar(100)') AS @ListingID FROM dbo.KB_XMod_Modules CROSS APPLY CONVERT(xml, instancedata).nodes('//instance') AS y(item) (instancedata is my column) Can anyone think of a work around for this ? Thanks

  • How can I make my PCI-E graphics card visible to Ubuntu when the motherboard has integrated graphics

    - by Norman Ramsey
    I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first: Integrated graphics PCI graphics PCI-Express graphics (PEG) I set the BIOS on PEG, but I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.) I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one. Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says Current usage: Unknown There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset! Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power. It gets all its power from the PCI-E slot; there is no external power connector. The BIOS is an AMI Award BIOS. My question: how can I make the PCI Express graphics card visible to Ubuntu?

  • PC only boots from Linux-based media and won't boot from DOS-based media

    - by xolstice
    I have this problem where the PC only seems to boot from a floppy disk or CD if it was created as a Linux-based bootable media. If it was created as a DOS-based bootable media the system just freezes at the starting point of the boot process. I originally asked this under question 139515 for CD booting only, and based on the given answers, I was under the impression the problem was with the CD-ROM drive; however, I have since installed a newly purchased CD-ROM drive and the same freezing occurs. This then made me try the DOS bootable floppy disk approach and I was quite surprised that it exhibited the same freezing problem. I then tried try a Linux bootable floppy and everything booted from it without any issues. As I mentioned in my original question, the PC was booting just fine from the DOS-based bootable CD, and then it suddenly decides to pull this freezing stunt. I can't remember if I changed anything in the BIOS settings that may I have caused the problem, but I am wondering if that could be the case - it is currently using the Award Module BIOS v4.60PGMA. Can anyone help?

  • ADUC Exchange tabs - Windows 7 & Exchange 2003

    - by John Gardeniers
    I have the admin tools install on a Win 7 64 bit machine but would like to see the Exchange tabs in ADUC. Googling shows this is a popular request and the most common solution (and the only one which appears to work to all) is to install Exchange Server Management for Vista using esmvista.msi /q. That may well have worked on beta versions of Win 7 but is definitely not working with my OEM copy of Win 7. Can this perhaps be made to work by installing from an Exchange 2007 CD (which I don't have at this time), bearing in mind that we have Exchange 2003 only? Can someone please offer a solution that works? I figure some of you must have solved this by now. Edit: I don't know if this is relevant or not but the Win 7 machine is also running Office 2010 Pro. About the bounty I had intended to award the bounty to gWaldo for having taken the extra steps to try to help me with this issue. However, as I was about to do so my screen started scrolling and I actually clicked on the answer posted by natxo asenjo, who's answer offended me, without realising it. Perhaps if I wasn't rushing I might have noticed but that's now history.
