• Library missing for executable file

  - by user1610406

  There's an executable I downloaded onto my Ubuntu 10.04 and I can't run because it's missing a library. I have also tried compiling the source with CMake. This is my Terminal output: zack@zack-laptop:~/Desktop$ ./MultiMC ./MultiMC: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory I think I need libssl 1.0 to run this file, but I'm not sure. Any help?

• How to make sysctl network bridge settings persist after a reboot?

  - by Zack Perry

  I am setting up a notebook for software demo purpose. The machine has 8GB RAM, a Core i7 Intel CPU, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit. The notebook is used as a KVM host and runs a few KVM guests. All such guests use the virbr0 default bridge. To enable them to communicate with each other using multicast, I added the following to the host's /etc/sysctl.conf, as shown below net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 Afterwards, following man sysctl(8), I issued the following: sudo /sbin/sysctl -p /etc/sysctl.conf My understanding is that this should make these settings persist over reboots. I tested it, and was surprised to find out the following: root@sdn1 :/proc/sys/net/bridge# more *tables :::::::::::::: bridge-nf-call-arptables :::::::::::::: 1 :::::::::::::: bridge-nf-call-ip6tables :::::::::::::: 1 :::::::::::::: bridge-nf-call-iptables :::::::::::::: 1 All defaults are coming back! Yes. I can use some kludgy "get arounds" such as putting a /sbin/sysctl -p /etc/sysctl.conf into the host's /etc/rc.local but I would rather "do it right". Did I misunderstand the man page or is there something that I missed? Thanks for any hints. -- Zack

• Materialized View vs POJO View based on Objects representing Oracle tables

  - by Zack Macomber

  I have about 12 Oracle tables that represent data that's being integrated from an external system into my web application. This data is going to be used in an informational and comparative manner for the clients using my web application. On one particular page of my web application, I need to combine data from 3 - 5 Oracle tables for display as an HTML table on the page. We are NOT currently using a framework (Apache Struts for instance) and we're not in a position to move this Java web application into one at this moment (I'm trying to get us there...). I am certainly not an architect, but I see one of two ways that I can effectively build this page (I know there are other ways, but these seem like they would be good ones...): 1. Create an Oracle Materialized View that represents what the HTML table should look like and then create a POJO based on the View that I can then integrate into my JSP. 2. Create POJOs that represent the Oracle tables themselves and then create another POJO that is the View used for the HTML table and then integrate that POJO into my JSP. To me, it seems the Materialized View would possibly offer quicker results which is always what we strive for in web applications. But, if I just create 12 POJOs that represent the Oracle tables and then build POJO Views off of those, I have the advantage of keeping all the code in one place for this and possibility for creating any number of different views and reusable components in my web application. Any thoughts on which one might be the better route? Or, maybe you know of an even better one?

• Pros & Cons: Hibernate vs. EJB 3

  - by Zack

  What are the advantages and disadvantages of Hibernate & EJB3 relative to each other? I found this post, but it didn't really address my question. If I don't have any particular tie to either technology, what would cause me to pick one over the other? Or are there situations where I would want to use both? Thanks, Zack

• How should I configure TRIM Support for LVM logical volumes?

  - by Zack Perry

  I am setting up a notebook for software demo purpose. The machine has a Intel Core i7 CPU, 8GB RAM, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit desktop. As it is, the SSD is configured to have a single volume group, with /boot, /swap, and / all in their respective logical volumes. They collectively consume 30GB space. I plan to use the remaining for logical volumes for KVM guests, all run Ubuntu 12.04 Server I would like to ensure that the SSD is utilized optimally. Although on this site, there are some great info about setting up TRIM support for file system setups that do not involve LVM, I have not found explicit guide regarding my planned setup. I did found this page which talks about adding issue_discards in /etc/lvm/lvm.conf. But in said file on my machine, I didn't find the cited content. I double-checked man lvm.conf(5), didn't see any mentioning of this option either. Thus, I'm not sure what to do. Furthermore, even say adding the option is the right thing to do, should I in my machine's /etc/fstab still add mount options such as noatime etc? Any tips, pointers, and/or further guidance are greatly appreciated.

• WiFi not working on Dell Inspiron 1564

  - by Zack Warren

  hope you can offer some help! I'm new to Ubuntu (and Linux for that matter), but I managed to install Ubuntu 12.04 yesterday on an old Dell Inspiron 1564 Laptop. Everything works fine, with the exception of the wireless connection. Using my wired ethernet, I was able to look up several solutions which seemed as if they would work, but I've had no luck. Currently, wireless does show as enabled, but all wireless networks are disconnected, in fact, none of the networks are even listed (and I can see them on other devices in the home). Let me know what you need to help me! Thanks in advance!

• Creating a retro-style palette swapping effect in OpenGL

  - by Zack The Human

  I'm working on a Megaman-like game where I need to change the color of certain pixels at runtime. For reference: in Megaman when you change your selected weapon then main character's palette changes to reflect the selected weapon. Not all of the sprite's colors change, only certain ones do. This kind of effect was common and quite easy to do on the NES since the programmer had access to the palette and the logical mapping between pixels and palette indices. On modern hardware, though, this is a bit more challenging because the concept of palettes is not the same. All of my textures are 32-bit and do not use palettes. There are two ways I know of to achieve the effect I want, but I'm curious if there are better ways to achieve this effect easily. The two options I know of are: Use a shader and write some GLSL to perform the "palette swapping" behavior. If shaders are not available (say, because the graphics card doesn't support them) then it is possible to clone the "original" textures and generate different versions with the color changes pre-applied. Ideally I would like to use a shader since it seems straightforward and requires little additional work opposed to the duplicated-texture method. I worry that duplicating textures just to change a color in them is wasting VRAM -- should I not worry about that?

• Advertising cookies ( ad sense ) on google chrome [closed]

  - by zack

  ok first I'm not sure if this is right stackexchange site to ask but I'm not sure if there is better one as question is quite general When I visit one site, and if this site runs google adsense campaign, I can see its ads on other sites. I suppose this is cookie from this site and than it's showing ads using the cookie However, I removed this specific cookie and cleared cache, and I can still see this same ad showing on other sites running adsense My question is, is there is something wrong with google chrome, is there a possibility that Google stores data within google chrome itself? If not, how else they could trace which ads to show?

• resttemplate getForObject map responsetype

  - by Zack Macomber

  I'm invoking a rest service that returns JSON like this: { "some.key" : "some value", "another.key" : "another value" } I would like to think that I can invoke this service with a java.util.Map as the response type but that's not working for me. I get this exception: org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [interface java.util.Map] Should I just specify String as the response type and convert the JSON to a Map?

• immediate=true is set on a jsf command button but still seeing validation

  - by Zack Macomber

  I have the following command button set up in a facelet: <h:commandButton action="#{addressAction.deletePreviousAddress}" value="#{bundle['button.deleteAddress']}" styleClass="deg-form-button" immediate="true"> <f:setPropertyActionListener target="#{addressAction.addressActionForm.previousAddress}" value="#{address}"> </f:setPropertyActionListener> </h:commandButton> In AddressAction, the following code gets run to delete a previous address on the form: public Enum<NavigationConstants> deletePreviousAddress() { addressActionForm.getPreviousAddresses().remove(addressActionForm.getPreviousAddress()); return NavigationConstants.addresses; } Before I made the address input components "required=true", this code worked fine and removed the previous address from the jsf form successfully. Right now, I can't successfully delete a previous address because validation is occurring and stating that the input components need to be filled in on the previous address record on the form. How can I bypass this validation? I thought the "immediate=true" attribute on the command button would have accomplished it but that's not cutting it in my case...

• Make JQuery UI Dialog automatically grow HEIGHT to fit its contents (width remains static)

  - by Zack Macomber

  Having looked into How can I make a JQuery UI Dialog automatically grow or shrink to fit its contents?, I am using the height: "auto" option when building a jQuery modal dialog box: $( "#dialog-message" ).dialog({ autoOpen: false, width: "400", height: "auto", show: "slide", modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); However, the height isn't "growing" to fit all of the contents. I'm still seeing a vertical scrollbar as in this image: Is there a way right in the definition code I listed to ensure that the height grows enough so that a vertical scrollbar doesn't show? Or, do I need to do this programmatically before opening the dialog box? Edit 1 Not sure why, but Chrome is displaying this fine but IE 8 isn't. I need it to specifically work in IE 8 so I believe I'm just going to put a bottom margin on the text.

• How do I "link narrations" in PowerPoint 2010 Beta?

  - by Zack Peterson

  I can record narration with PowerPoint 2010, but it seems that it will only embed it into the presentation file. Older versions of PowerPoint allowed the audio to be saved as external sound files. I'd like to perform noise-reduction and minor editing outside of PowerPoint. Has Microsoft removed the "link narrations" option from PowerPoint 2010?

• Accessing IPv6 router interface from a minimal Fedora installation?

  - by Zack

  I've recently installed Fedora 16 and am trying to set up a simple apache server. The only problem I've run into so far is that I'm unable to access my router's web interface from any box on my network. It assigns addresses via dhcp, and the router always responds to a ping. The server is also picking up an IP from the router on the proper subnet. Now, all I really need to do is forward a port, however I am receiving "Unable to connect" through the web interfaces and "connection refused" via telnet. What are my options, and how might I go about troubleshooting this? Will I need the server's ip to be static in order to change these settings? The router is a "Netopia" model, if that helps.

• Virtual Windows desktop

  - by Zack

  Is there any virtual desktop software that can virtualize desktop just like a virtual desktop to sandbox (sort of like virtualization and sandbox combined). I want to create many desktop and each of them must be sandbox. For example if I have virus infected in one of the desktop, I just have to clear or close the desktop and everything is fine. Is there any software that can do that kind of jobs that I have mentioned? Remember I am not asking recommendation of software, but the software that can do the job. UPDATE: I mean that every virtual desktop is working as a virtual box or sandbox. Clearing or closing the desktop will work as shutting down that virtual box.

• Linux Programs for pulling measurements from graphics

  - by Zack

  As a front-end developer, I'm often given graphics of web sites and told pretty much, "Make it work." I've recently started working on Linux 100% of the time and was wondering if there's any programs out there that're good for "digesting" graphics. All I do, pretty much, is draw little selection boxes and takes notes on their dimensions; I also slice out a piece of the graphic (i.e. copy out just the part of the graphic I need for to make the same effect in CSS). Before now I've been very happy with Fireworks, but I need something for Linux, any suggestions? As a note, I mainly deal with pixel based graphics, so the program being vector based isn't a necessity.

• PLS HLP Chrome & Internet Explorer won't connect after infected Fire Fox works.

  - by Zack

  HI Guys Please Help I am pretty New Here. I'm having problems. Cannot connect with chrome or Internet Explorer. Fire Fox works fine. It seems it happens when I was infected by a "Trojan Horse Generic 17.BWIK" and a "Trojan Horse SHeur.UHL", when I reply to a post for a Thread I posted. I have removed the treat and got Fire Fox working, "so i think", but not G'Chrome or IE still cannot connect. I do not want to loose Chrome History so re-setting would be my last option and uninstall and install will be out of the question. Is there a way around this? I am using XP Pro on a desktop and DSL connection. Be aware from "Fake_Antispyware.FAH", which I had on my computer, I just found out while doing this, according to my AVG anti-virus security. Please can you direct me for a cure. Thank you in advance for your sincere willingness contributions.

• .NET Framework 1.1 on IIS 7

  - by Zack Peterson

  I have inherited a .NET Framework 1.1 web site that I must host with IIS 7 on Windows Server 2008. I'm having some trouble. 1. Installation I installed .NET Framework 1.1 following these instructions. The installation automatically created a new Application Pool "ASP.NET 1.1". I use that. 2. Trouble When I launch the web site I see web.config runtime errors: The tag contains an invalid value for the 'culture' attribute. I fix that one and then see: Child nodes are not allowed. I don't want to keep playing this whack-a-mole game. Something must be wrong. 3. Am I sure this is .NET 1.1? I examine the automatically created application pool. I see that it's 1.1. Advanced Settings... Basic Settings... This doesn't seem right. While 1.1 is set, it's not an option in the Advanced drop down selectors. And why in the Basic box is it just "v1.1" and not ".NET Framework v1.1.4322"? That would be more consistent. 4. I cannot create other .NET 1.1 App Pools I cannot select .NET Framework 1.1 for other application pools. It's not an option in the drop down selectors. What's up with that? What now? Why isn't v1.1 an option for all AppPools? How can I verify my application is in fact using .NET Framework 1.1? Why might I get these runtime errors?

• Suspended Laptop Cannot Wake Up - Ubuntu

  - by Zack

  I've got an ASUS G73JH, and whenever I suspend it or hibernate it, it will not wake up. The screen stays backlight but is black. I can't: Awaken it with the keyboard Awaken it with the mouse Soft power-off by pressing the power button I have to hold down the power button and shut it down that way, and this seems a little unreasonable. Is there a place I could look for more detail as to what's causing this? Is there a known quick-fix to this issue?

• unable to destroy windows 2008 r2 failover cluster after SAN rebuild

  - by Zack

  I created a windows 2008 r2 failover cluster for a sql 2008 active/passive cluster. This two node cluster was using a SAN device for a quorum disk resource as well as MSDTC resource. Well....I decided to reconfigure the SAN device, but I didn't destroy the cluster first. Now that the quorum disk and mstdc disk are completely gone, the cluster is obviously not working. But, I can't even destroy the cluster and start again. I've tried from the Windows Clustering tool, as well as the command line. I was able to get the cluster service to start using the "/fixquorum" parameter. After doing this I was able to remove the passive node from the cluster, but it wouldn't let me destroy the cluster because the default resource group and msdtc are still attached as resources. I tried to delete these resources from both the GUI tool, as well as command line. It will either freeze for several minutes and crash the program, or once it even BSOD'd the server. Can someone advise on how to destroy this cluster so I can start over?

• Linux Uninstalling errors

  - by Zack

  I want to uninstall back-track 5 so I deleted the partitions for back-track os. After deleting the partition that used to be for back-track becomes free space as in picture. But I can't delete that partition nor creating a new partition. I used G-Parted from hiren boot cd but it says there is no partition table, you need to create a partition table. But actually I have 5 partitions already. And I thought of restarting might fix it. But after showing post screen my laptop show grub error. I don't know what to do, and I tried to install back-track again to fix the problem but it also says that i do not have any partitions. I can only boot windows by passing through hiren boot cd. But most of the time My computer is not recognizing the external dvd drive, nor the internal so i have to restart again and again, hoping to catch the time computer recognize the dvd drive. Can I change the boot loader to correct the grub error? SOLVED : I have solved the grub error by writing MBR again by using EasyBCD But I still have the format error.

• Reducing video mode switching during Linux boot

  - by Zack

  When I boot up my desktop computer, which only has Linux on it, the video mode and/or console font gets switched four times: When GRUB starts, it switches from 80x25 text to a graphical mode so it can draw a pretty background behind its menu; GRUB then goes back to 80x25 text after I pick something from the menu; When the KMS driver for my video card loads, it switches to a much higher-resolution text mode (I don't know if this is a hardware text mode or not); Finally X starts and it goes graphics and stays that way. I think this last switch does not change the resolution of the video mode, only the graphicalness. I'd like to get rid of as many of these mode switches as possible. Ideally, when GRUB takes over from the BIOS it would go directly to the same high-resolution text mode that the KMS driver selects, and the display would stay in that mode till X starts and brings up graphics. I am under the impression that this is possible by mucking with the kernel command line and/or the GRUB console module load parameters, but I don't know the details. GRUB 1.98+20100706, kernel 2.6.32.15 using Nouveau video drivers. Distro is Debian unstable. Please no answers that involve recompiling anything or cobbling together bleeding-edge kernel/driver combinations, I don't care enough about this to go to that much trouble. EDIT: Tobu suggests setting GRUB_GFXMODE to the full pixel resolution of the monitor, and GRUB_GFXPAYLOAD_LINUX=keep to avoid the mode switch after the menu goes away. This does part of what I want, but winds up being worse overall. There's no mode switch after the menu, but there's still a painfully-slow screen repaint (I should probably just give up on GRUB's gfxmode, it's waaaay too slow at 1920x1200). More seriously, there's now a double mode switch when nouveaufb loads, along with fun-looking error messages in dmesg [ 5.923798] [drm] nouveau 0000:02:00.0: allocated 1920x1200 fb: 0x40250000, bo ffff8801ba5f4600 [ 5.923802] fb: conflicting fb hw usage nouveaufb vs EFI VGA - removing generic driver [ 5.923821] [drm] nouveau 0000:02:00.0: PFIFO_INTR 0x00000010 - Ch 1 ("PFIFO_INTR" message repeats 400+ times) [ 5.925609] Console: switching to colour dummy device 80x25 [ 5.925802] Console: switching to colour frame buffer device 240x75
