• Why is hibernation still used?

  - by Moses

  I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

• How do I negotiate for colo space?

  - by randy melder

  I guess this isn't a technical question, but it definitely is something IT teams deal with, so here goes: I'm looking at getting a rack at a local colocation facility. I'm weighing the options versus building out in a cloud platform. We are REALLY low bandwidth and power. There's a total of six hosts for the total operation. You can assume we use <= 10 amps of power and <= 2Mbps 95th percentile. Do you have any advice for getting the best deal?

• What about IPv4 class E?

  - by Luc

  IPv4's class E network (240.0.0.0/4) contains 268 million addresses. Despite the advertisements for IPv6, claiming we have ran out of address space, this block ironically still claims to be "Reserved for future use". Why hasn't this block been freed up yet? Of course, IPv6 should be promoted instead of freeing up more IPv4 addresses, but we've seen the address shortage coming for years. There has even been a time they weren't sure there was enough time to develop IPv6 before we would run out of addresses. Why didn't they free up this block already? And is there any chance these addresses will be used in the future, like when IPv6 is fairly widely implemented but we still need IPv4 for backwards compatibility? It will be phased out regardless, but then ISPs don't have to employ NAT for IPv4 compatibility.

• Get the interface and ip address used to connect to a specific host (ip)

  - by umop

  I'm sure this has been asked and answered before, but I wasn't able to find it, so hopefully this will at least link someone to the right place. I want to find out my local interface and ip address used to reach a certain host. For instance, if I had 3 adapters connected to my box and they all three went to different networks, I'd like to know which of the three (specifically, its ip address) is used to reach my.local.intranet (in this case, it would be a vpn tunnel interface). I suspect this is a job for ifconfig or traceroute, but I haven't been able to find the correct switches. I'm running OSX 10.7 (Darwin) Thanks!

• Blank CD less space than there actually is (mac)

  - by Frost Shadow

  I just bought a TDK HC-R90 Recordable blank CD that's supposedly 800 MB, but when I put it in my Macbook, Finder says there's only 100 MB available. WTF? I'm trying to burn the 575.8 MB Anonym.OS live cd (.iso), I dunno if that makes a difference.

• Problem accessing the remote working space on my new SBS 2008 box

  - by Dabblernl

  This supposedly easy to install OS is starting to drive me nuts... SYMPTOMS: When trying to connect to the remote workplace I get (and ignore) the security warning because I am currently testing with the self issued certificate. After loggin in the remote workplace's main screen displays but the images on it do not load. When I try to click the email link I am thrown back to the login screen. If I try the login to exchange directly by typing in the remote.mydomain.com/owa address I get a 403 error that I am denied access. The problem occurs on both a vista and a win 7 machine. It seems that some security setting is playing tricks with me. How can I troubleshoot this?

• Wrong version of php used be IIS

  - by user1070125

  Long ago I installed php5.2 using a installer on IIS. Recently I installed PHP Manager and upgraded to php5.3 simly by unzipping the downloaded file and then used the "Register new php version" in PHP Manager. I did this for the global scope for all sites. This works OK. Once in a blue moon errors are written to the php5.2 errorlog even though that verion is not used anymore. The errors are typical 5.3 specfic functions that are not supported in 5.2. How can it be? Can I safely uninstall php5.2 using the uninstaller (i think it added some stuff to the env paths)?

• Do I need to reserve space before installing Ubuntu alongside Windows 7?

  - by CRM Junkie

  I had Windows 7 32 bit on my existing system, but I am planning to install Ubuntu alongside it. So, I just decided to do a fresh installation of both the operating systems. When I insert the Windows 7 DVD, I can create 3 partitions at maximum, with one being the one where Windows 7 will be installed. I just wanted to know – do I need to keep some un-partitioned space for Ubuntu to install? By "unpartitioned space" I mean the space left after creating 3 partitions for Windows 7. I have a 500 GB HDD, so the three partitions I would be creating are 120 GB, 120 GB and 120 GB. The rest is shown as some logical drive, is that unpartitioned space? Can I install Ubuntu over there? I am pretty sure the space shown as logical won't be available as drives when I log into Windows 7. Is that space lost or can I use that to install ubuntu?

• Maximum hard drive space for an Xserve G5

  - by wjlafrance

  At my college we're upgrading an Xserve G5 (RackMac3,1) to be a file server for some courses. Currently it has one sled with a 75GB drive. Obviously, this isn't enough. I've tried some Googling on this matter and I'm hearing a ton of different stuff - custom firmware, size issues, etc. So, for anyone who knows, what's the actual lowdown on this machine. We want to put in three 2TB drives using three standard sleds, replaced with third-party drives. Is this possible?

• Isn't ethernet used for LAN?

  - by Alraxite

  I'm not really knowledgeable about networking stuff, hence the stupid question. I read that ethernet was used for LAN connections but I'm pretty sure what I'm currently using to connect to the internet is 'ethernet'. The only knowledge that I have about networking is that there are two types of internet connections: Dial-up and broadband. And broadband can be either DSL or cable. So where does ethernet come from? The only thing I can tell is that I have a DSL model and there is an ethernet port at the back of it, a cable from which runs to a port in the back of my CPU. So, can ethernet be used to connect to the internet? Is it a subtype of DSL? I'm really confused about this, so I would really appreciate if someone could explain this to me. Also, I will apologize if this isn't the right place to ask.

• Coordinate spaces and transformation matrices

  - by Belgin

  I'm trying to get an object from object space, into projected space using these intermediate matrices: The first matrix (I) is the one that transforms from object space into inertial space, but since my object is not rotated or translated in any way inside the object space, this matrix is the 4x4 identity matrix. The second matrix (W) is the one that transforms from inertial space into world space, which is just a scale transform matrix of factor a = 14.1 on all coordinates, since the inertial space origin coincides with the world space origin. /a 0 0 0\ W = |0 a 0 0| |0 0 a 0| \0 0 0 1/ The third matrix (C) is the one that transforms from world space, into camera space. This matrix is a translation matrix with a translation of (0, 0, 10), because I want the camera to be located behind the object, so the object must be positioned 10 units into the z axis. /1 0 0 0\ C = |0 1 0 0| |0 0 1 10| \0 0 0 1/ And finally, the fourth matrix is the projection matrix (P). Bearing in mind that the eye is at the origin of the world space and the projection plane is defined by z = 1, the projection matrix is: /1 0 0 0\ P = |0 1 0 0| |0 0 1 0| \0 0 1/d 0/ where d is the distance from the eye to the projection plane, so d = 1. I'm multiplying them like this: (((P x C) x W) x I) x V, where V is the vertex' coordinates in column vector form: /x\ V = |y| |z| \1/ After I get the result, I divide x and y coordinates by w to get the actual screen coordinates. Apparenly, I'm doing something wrong or missing something completely here, because it's not rendering properly. Here's a picture of what is supposed to be the bottom side of the Stanford Dragon: Also, I should add that this is a software renderer so no DirectX or OpenGL stuff here.

• overwrite a file which is already used by another process

  - by Ahmy

  I have a web site and i am showing videos to visitors, at the admin side i am filling the form of video and upload video file and sometimes i need to change(update) the video so i update the video by uploading another one, when i create the video in the first time i concatenate a datetime variable with the video name to avoid repeatition(file already exist) and when updatting the video the problem appears.... as if i upload the new video with the previous name so it will replace the previous one and in this case if the video is used by another process it will fail and the second option(which i am already using) is to upload a new video and concatenating new datetime variable with video title, so the previous and the new video will exist in the same directory and in this case i will lose too much space in my server directory as i have unused videos which takes space which in future will cause problem to me in the disk space so how can i solve this problem ? Hope that my question is clear....thanks in advance for any try

  Hi, Given this example XML file: <doc> <tag> Hello ! </tag> <tag> My name is John </tag> </doc> And the following XSLT sheet: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <xsl:for-each select="doc/tag"> <xsl:value-of select="."/> </xsl:for-each> </xsl:template> </xsl:stylesheet> How should I change it in order to ignore line feeds and convert any group of white-space characters to just one space in the items? In other words, I would like to obtain: Hello! My name is John Without all those those silly line feeds. ...the question is how. Thanks in advance !

• Splitting an image in GWT results in unwanted white space

  - by rancidfishbreath

  I am using GWT 2.03 and am have an image that I want to place partially in an area with a background and partially above a background. I am using a FlexTable to try to accomplish this and have used GIMP to cut the image into two sections. I am trying to load the top part of the image into row 0 and the bottom part of the image into row 1. I set the alignment of the top image to ALIGN_BOTTOM but there is a bit of space at the bottom of cell and so the two parts of the picture don't touch. Here is an image showing what I am talking about. I set the background of the cell to be yellow show where the cell boundaries are. The bottom image and background are rendering correctly. Here is the relevant code snippet: FlexTable table = new FlexTable(); table.setCellSpacing(0); table.setCellPadding(0); table.setBorderWidth(0); FlexCellFormatter formatter = table.getFlexCellFormatter(); table.setWidget(0, 0, topImage); formatter.setStyleName(0, 0, "topImageStyle"); formatter.setVerticalAlignment(0, 0, HasVerticalAlignment.ALIGN_BOTTOM); table.setWidget(1, 0, bottomImage); formatter.setStyleName(1, 0, "bottomImageStyle"); How can I get rid of that space between my image and the cell boundary?

• BlackBerry:Reduce space between 2 buttons in HorizontalFieldManager

  - by user469999

  hi In blackberry i have created a horizontal field managar and added some buttons of small size to it to display toolbar at the bottom of the screen.But my problem is there is too much space between the 2 buttons.I have to reduce this space between 2 buttons so that i can manage to place atleast 6 buttons at the bottom of the screen.I am using the BFmsg.setMargin(305,0,0,40) statement. can anyone please help me on this. Following is my code : BFcontacts = new ButtonField("Cnt") { protected void paint(Graphics graphics) { //Bitmap contactsbitmap = Bitmap.getBitmapResource("contacts.jpg"); //graphics.drawBitmap(0, 0, contactsbitmap.getWidth(), contactsbitmap.getHeight(), contactsbitmap, 0, 0); graphics.setColor(Color.WHITE); graphics.drawText("Cnt",0,0); } }; BFcontacts.setMargin(305,0,0,10);//vertical pos,0,0,horizontal pos HFM.add(BFcontacts); BFmsg = new ButtonField("Msgs") { protected void paint(Graphics graphics) { //Bitmap msgsbitmap = Bitmap.getBitmapResource("messages.jpg"); //graphics.drawBitmap(0, 0, msgsbitmap.getWidth(), msgsbitmap.getHeight(), msgsbitmap, 0, 0); graphics.setColor(Color.WHITE); graphics.drawText("Msgs",0,0); } }; BFmsg.setMargin(305,0,0,40);//vertical pos,0,0,horizontal pos : original HFM.add(BFmsg); add(HFM) Thanks in advance

• Reserve space for initially hidden widget in QVBoxLayout

  - by Skinniest Man

  I am using a QVBoxLayout to arrange a vertical stack of widgets. I want some of them to be initially hidden and only show up when a check box is checked. Here is an example of the code I'm using. MyWidget::MyWidget(QWidget *parent) : QWidget(parent) { QVBoxLayout *layout = new QVBoxLayout(this); QLabel *labelLogTypes = new QLabel(tr("Log Types")); m_checkBoxCsv = new QCheckBox(tr("&Delimited File (CSV)")); m_labelDelimiter = new QLabel(tr("Delimiter:")); m_lineEditDelimiter = new QLineEdit(","); checkBoxCsv_Toggled(m_checkBoxCsv-isChecked()); connect(m_checkBoxCsv, SIGNAL(toggled(bool)), SLOT(checkBoxCsv_Toggled(bool))); QHBoxLayout *layoutDelimitedChar = new QHBoxLayout(); layoutDelimitedChar-addWidget(m_labelDelimiter); layoutDelimitedChar-addWidget(m_lineEditDelimiter); m_checkBoxXml = new QCheckBox(tr("&XML File")); m_checkBoxText = new QCheckBox(tr("Plain &Text File")); // Now that everything is constructed, put it all together // in the main layout. layout-addWidget(labelLogTypes); layout-addWidget(m_checkBoxCsv); layout-addLayout(layoutDelimitedChar); layout-addWidget(m_checkBoxXml); layout-addWidget(m_checkBoxText); layout-addStretch(); } MyWidget::checkBoxCsv_Toggled(bool checked) { m_labelDelimiter-setVisible(checked); m_lineEditDelimiter-setVisible(checked); } I want m_labelDelimiter and m_lineEditDelimiter both to be initially invisible and I want their visibility to toggle with the state of m_checkBoxCsv. This code acheives the functionality I desire, but it doesn't seem to reserve space for the two initially hidden widgets. When I check the checkbox, they become visible, but everything is kind of scrunched to accomodate them. If I leave them initially visible, everything is laid out just the way I would like it. Is there any way to make the QVBoxLayout reserve space for these widgets even if they're initially invisible?

• "java.lang.OutOfMemoryError: Java heap space" in image and array storage

  - by totalconscience

  I am currently working on an image processing demonstration in java (Applet). I am running into the problem where my arrays are too large and I am getting the "java.lang.OutOfMemoryError: Java heap space" error. The algorithm I run creates an NxD float array where: N is the number of pixel in the image and D is the coordinates of each pixel plus the colorspace components of each pixel (usually 1 for grayscale or 3 for RGB). For each iteration of the algorithm it creates one of these NxD float arrays and stores it for later use in a vector, so that the user of the applet may look at the individual steps. My client wants the program to be able to load a 500x500 RGB image and run as the upper bound. There are about 12 to 20 iterations per run so that means I need to be able to store a 12x500x500x5 float in some fashion. Is there a way to process all of this data and, if possible, how? Example of the issue: I am loading a 512 by 512 Grayscale image and even before the first iteration completes I run out of heap space. The line it points me to is: Y.add(new float[N][D]) where Y is a Vector and N and D are described as above. This is the second instance of the code using that line.

• Image on mouseover takes space on PageLoad.
