• GNU Screen Draw Lag

  - by Daeden

  I like using screen with multiple splits. I usually like 3 sections Resource Monitoring using HTop Text Editor using VIM Command line using Bash My issue is that, when I am doing something that writes a good deal of text to STDOUT like running Make and if I am focused on that section, Screen lags on me. So much so, that the other sections no longer update and screen is not responsive to commands like CTRL-A + TAB. I'm not entirely sure what the problem is, but it appears to have something to do with the cursor location which blinks wildly while this is happening. I'm aware that using the vertical split functionality of Screen can lead to lag, but is this the cause? If so, is there a way to fix it aside from redirecting STDOUT?

• How do I hookup a dual video card Crossfire rig to a single monitor?

  - by Alexed

  I just received a new Alienware box preinstalled with two nice shiny ATI 6950 graphics cards. My goal is to use both of them to give me really good resolution and frame rate on my single monitor. There's zero documentation with the Alienware box and nothing I can find online. Do I just plug the monitor into one of the cards, and expect the two cards to do magic internally? The ATI Crossfire website indicates a need for an "external crossfirex connection cable". Do I need to buy one of these? If so, what kind of cable is it? The AMD Catalyst Control Center shows the second card as "Linked" but when I go to the AMD Overdrive section, the second card is at zero temperature, and clock, suggesting it's not actually doing anything. What do I need to do to make use of both cards? Is it something that doesn't kick in until I do something graphically intensive?

• Windows XP, USB-Stick and multiple Partitions

  - by Bobby

  Hello. I've got an USB-Stick with multiple Partitions on it (FAT32 (active), FAT32, Ext2 <-- that's another story) and it seems like that my Windows XP can only mount the first partition of the stick. If I try to mount the second one using the volume manager it tells me that I need to make it active and reboot...is it really that limited or am I just missing something here? Partitions: FAT32, System Rescue CD, bootable and active FAT32, some tools ext2, some data (I know that I need extra drivers etc., but that's not asked here. Edit (Solution): Thanks to the answer with the RMB (ReMoveable Bit) I was able to dig up a solution described at this site (Section: On flash drive only the first partition works). Basically, there's an Hitachi Driver available which filters the RMB on Driver-Level, which just needs to be a little modified to function with basically every USB-Stick. All you need to do is adding the "Device Instance ID" to the driver and then use this driver.

• Canon HV20 recognized, but no drivers in Windows 7 x64

  - by Tuminoid

  My Canon HV20 camcorder is properly recognized when connected via Firewire to Windows 7 x64, but no drivers are installed for it. Windows or I cannot locate any drivers for it as, but it should be working off-the-shelf. I googled a lot, and found instructions to set IEEE 1394 host to legacy mode via Device Manager, but Windows doesn't offer me the legacy option at all. If I check the properties of Canon&HV20 device in Other devices section it says The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element. It used to work just fine on my previous installation of Vista x64 and same hardware :/

• Why and when should one call _fpreset( )?

  - by STingRaySC

  The only documentation I can find (on MSDN or otherwise) is that a call to _fpreset() "resets the floating-point package." What is the "floating point package?" Does this also clear the FPU status word? I see documentation that says to call _fpreset() when recovering from a SIGFPE, but doesn't _clearfp() do this as well? Do I need to call both? I am working on an application that unmasks some FP exceptions (using _controlfp()). When I want to reset the FPU to the default state (say, when calling to .NET code), should I just call _clearfp(), _fpreset(), or both. This is performance critical code, so I don't want to call both if I don't have to...

• What is the default value for Empty Temporary Internet Files when browser is closed in IE8?

  - by schellack

  We have four different machines that all have "Empty Temporary Internet Files when browser is closed" set to true (checked) in IE8's Internet Options (located under the Security section in the Advanced tab). No one remembers checking that checkbox to turn on the setting. What is the default value supposed to be? I'm specifically interested in Windows 7 and Windows XP. I have run rsop.msc on one of the corporate machines—3 of the 4 are members of a corporate network/domain—and see this under User Configuration, which makes the current scenario seem even stranger: The Local Group Policy Editor (gpedit.msc) also shows the Configure Delete Browsing History on exit setting to be Not configured (under Computer ConfigurationAdministrative TemplatesWindows ComponentsInternet ExplorerDelete Browsing History).

• Setting the Server Port in D-Link Router for eMailing Logs

  - by Synetech

  Does anyone know how to set the port for the email server in the Status->Log section of the D-Link DI-524? I’ve tried the setting below but it does not seem to work. I don’t want to use the default port 25 if I can avoid it. (No, the server and email address in the snap are irrelevant, you can replace the server with hotmail.com or whatever and address with a valid one; the question I am trying to figure out is how to set the port.)

• business object and codelist

  - by feiroox

  Hi How to design a business object? I have a library which returns me an Object which have ten lists of other different objects. I need to store it into database all. List of objects are often like: class Item { private int id; private String name; private double point; } But the name is often the same. Like basic title of the product or code. Containing from 3 characters up to 70characters. Should I make conversion for every Object to: (or something similar) class ConvertedItem { private int id; private int code; private double point; } And have a separated table of codes ( I guess around 60). Or do not bother with duplicated stuff? It's not mission critical app. What would you do in my case? thanks in advance

• vim: highlighting a search term without moving the cursor

  - by ajwood

  Using Vim, I sometimes find myself staring at a section of source code for a while and suddenly want some variable on the screen to pop out. That's easy: /<var> which highlights them all. My issue is that it more often than not the search shifts my window so I'm not looking at the source code from the same place. Even if it's only shifted a few lines, it's still throws me off since I need to take a few seconds to figure out where things have moved to. Is it possible to highlight a search term without moving the cursor to the next match?

• Filtering attachment types in Google Apps (free Google Business)

  - by Ernest

  We have Google apps in our company for mail delivery, our business can't pay the business version yet, however, we need to control the attachment types that employees download. We recently switched from another hosting provider who recomended us to plug Google Apps for mail when we moved the domain, we had a firewall before which was able to prevent certain file types to be downloaded. I know the business version has section for filtering mail (postini services). Is there a hack around my problem? Anyone ever had this problem? Thank you! UPDATE: The main problem is gmail apps uses ssl connection, can this be changed ? how can i get the firewall to filter files only allowing *.doc, *.xls y *.pdf.

• Is it possible to create an efficient UDF alternative to Excel's CUBEVALUE function?

  - by bright

  We'd like to create a simpler alternative to Excel's CUBEVALUE function for retrieving data from an OLAP server. The details aren't critical, but briefly, our function will "know" the source connection and accept a very simple ticker-like parameter and a date, in place of CUBEVALUE's MDX-style parameters. This is for internal use within our firm, just FYI. However, Excel has optimized CUBEVALUE so that calls to the OLAP server are batched. Question: Is there a way to code the new function so that it can similarly batch calls rather than issue a separate query for each cell?

• Backup Google Calendar programmatically: https://www.google.com/calendar/exporticalzip

  - by Michael

  I'm struggling with writing a python script that automatically grabs the zip fail containing all my google calendars and stores it (as a backup) on my harddisk. I'm using ClientLogin to get an authentication token (and successfully can obtain the token). Unfortunately, i'm unable to retrieve the file at https://www.google.com/calendar/exporticalzip It always asks me for the login credentials again by returning a login page as html (instead of the zip). Here's the critical code: post_data = post_data = urllib.urlencode({ 'auth': token, 'continue': zip_url}) request = urllib2.Request('https://www.google.com/calendar', post_data, header) try: f = urllib2.urlopen(request) result = f.read() except: print "Error" Anyone any ideas or done that before? Or an alternative idea how to backup all my calendars (automatically!)

• How do you passthrough native SATA drives to a guest on ESXi?

  - by John

  I have ESXi 4.0 running on an Intel DX58S0 Mothboardboard with an Intel Core i7 930 processor. VT-d is also enabled. I have three drives in the system, drive 0 is used for ESXi. Drive 1 and 2 contain data from an older machine and show up under the "Storage Adapters" section in configuration. I would like to allow a guest machine to access the data on these drives (as nativly as possible). I have enabled passthrough of the motherboard's built in SATA controller (Intel/Marvell 88SE6121 ). This controller shows up in my guest OS, but the guest shows no drives aside from the normal virtual drive. I have tried a Linux guest and Windows7. I have also configured the host machine to try IDE/RAID/ACHI modes for the SATA controller. Any ideas how I can configure one of my guests to get at the raw data on these drives?

• Simple 2 way encryption for C#

  - by Matt Dawdy

  I'm looking for very simple encrypt and decrypt functionality for some data. It's not mission critical. I need something to keep honest people honest, but something a little stronger than ROT13 or Base64. I'd prefer something that is already included in the .Net framework 2.0 so I don't have to worry about any external dependencies. Pre-emptive EDIT: I really don't want to have to mess around with public/private keys, etc. I don't know much about encryption, but I do enough to know that anything I wrote would be less than worthless...in fact, I'd probably screw up the math and make it trivial to crack.

• How do I safely destroy a dialog window of a wxPython application?

  - by Akira

  I created a wxPython application which shows some messages on a dialog window. The dialog window is needed to be force-destroyed by the application before I click the dialog OK button. I used wx.lib.delayedresult to make the destroy call. My code is: import wx dlg=wx.MessageDialog(somewindow,'somemessage') from wx.lib.delayedresult import startWorker def _c(d): dlg.EndModal(0) dlg.Destroy() def _w(): import time time.sleep(1.0) startWorker(_c,_w) dlg.ShowModal() This can do what I desire to do while I got a error message below: (python:15150): Gtk-CRITICAL **: gtk_widget_destroy: assertion `GTK_IS_WIDGET (widget)' failed How do I "safely" destroy a dialog without clicking the dialog button?

• Tag Cloud Data Backend

  - by Waldron

  I want to be able to generate tag clouds from free text that comes from any number of different sources. For clarity, I'm not talking about how to display a tag cloud once the critical tags/phrases are already discovered, I'm hoping to be able to discover the meaningful phrases themselves... preferable on a PHP/MySQL stack. If I had to do this myself, I'd start by establishing some kind of index for words/phrases that gives a "normal" frequency for any word/phrase. eg "Constantinople" occurs once in every 1,000,000 words on average (normal frequency "0.000001"). Then as I analyze a body of text, I'd find the individual words/phrases (another challenge!), find frequencies of each within the input, and measure against the expected freqeuncy. Words that have the highest ratio against expected frequency get boosted priority in the cloud. I'd like to believe someone else has already done this, WAY better than I could hope to, but I'll be damned if I can find it. Any recommendations??

• Where to find a unique session ID at design time in .Net WinForms.

  - by Jules

  I've created a custom clipboard because it's not possible to make my whole class map serializable - which is a requirement for the windows clipboard. However, I need to distinguish between users who are using my clipboard through a unique id. Basically, I want to be able identify a person who is sat at one PC with one or more copies of visual studio (or similar) open. How do I do that? ps: This is at design-time. pps: It's not critical that it should work between copies of visual studio. One copy would be fine, or even one design surface.

• How to I create a table of contents in a Word document that has a mind of it's own?

  - by Howiecamp

  I'm embarrassed to admit that I'm struggling to get a table of contents going in a Word doc that's already been created. I know enough to understand that the TOC is based on the type of the header/style and indentation. My approach so far has been to auto-generate the TOC and then try (unsuccessfully) to fix the problems; perhaps this isn't the best approach in this situation. What's happening is that the TOC is missing half my sections and for others it's adding way too much detail. Again my sense is I have to "fix" individual section headings but I haven't been successful so far.

• custom windows 7 themes

  - by Ieyasu Sawada

  I found one at deviantart.com: http://browse.deviantart.com/?qh=&section=&q=adagio+theme#/d2zwu22 I like the adagio theme, except that you cannot see the content of the address bar unless you click your mouse on it. Is there any site that you know wherein I could download custom themes for windows 7. Themes that would actually modify the looks of it. Not just the colors,icons and wallpaper. Can you recommend a theme for me. A theme that would modify the navigation, close, min, max buttons in the windows explorer

• How to: Inline assembler in C++ (under Visual Studio 2010)

  - by toxic shock

  I'm writing a performance-critical, number-crunching C++ project where 70% of the time is used by the 200 line core module. I'd like to optimize the core using inline assembly, but I'm completely new to this. I do, however, know some x86 assembly languages including the one used by GCC and NASM. All I know: I have to put the assembler instructions in _asm{} where I want them to be. Problem: I have no clue where to start. What is in which register at the moment my inline assembly comes into play?

• IIS7 Rewrite rule being duplicated across 2 different websites (unwanted)

  - by Matt

  We have a IIS7 on Windows Server 2008. It is hosting a handful of sites, on a handful of ip addresses. 2 of those sites are actually wildcards on the domain: *.firstdomain.com *.seconddomain.com However, I am finding that any URL Rewrite rules I add for one of these "websites", is automatically in the URL Rewrite section for the other. Similarly, if I disable the rule in in one, it disables in the other. This doesn't happen with the other sites defined on this server, just these two. I look at the parent (top level, the server as a whole), and the rule is not there. Any idea what's going on here?

• nginx proxy pass redirects ignore port

  - by Paul

  So I'm setting up a virtual path when pointing at a node.js app in my nginx conf. the relevant section looks like so: location /app { rewrite /app/(.*) /$1 break; proxy_pass http://localhost:3000; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } Works great, except that when my node.js app (an express app) calls a redirect. As an example, the dev box is running nginx on port 8080, and so the url's to the root of the node app looks like: http://localhost:8080/app When I call a redirect to '/app' from node, the actual redirect goes to: http://localhost/app

• It's easy to set a breakpoint when debugging VBA, but how about a "startpoint" or a "skippoint"?

  - by PowerUser

  I'm debugging a subroutine in my VBA code. I want to ignore the first half and just run the second half. So, is there a way to set a 'startpoint'? Also, is there an easy way to ignore a specific line of code other than commenting? If not, I'll just continue commenting out all the code I don't want run. The problem with this, of course, is that I have to remember to uncomment the critical code before I send it on to Production.

• what are the recent dataStructure and algorithms that one should know?

  - by Shamik

  Recently I came across the SkipList data structure. It really helped me to solve one otherwise critical problem to be solved. I was struggling to solve the same problem with Balanced Binary tree but it became very complex as the tree needs to be always balanced and I wanted to know the existence of not only a particular value but values in certain range. SkipList helped me to solve that problem effectively. I am wondering what else data structures that I need to know? I know - Array, List, Stack, Queue, Linked List, hashtable, tree and its different forms like B-tree, Trie etc. Would like to know if you find some other data structure/concept very interesting to know yet effective enough to be used in a daily development cycle.
