• Copy to USB memory stick really slow?

  - by Eloff

  When I copy files to the USB device, it takes much longer than in windows (same usb device, same port) it's faster than USB 1.0 speeds (1MB/s) but much slower than USB 2.0 speeds (12MB/s). To copy 1.8GB takes me over 10 minutes (it should be < 3 min.) I have two identical SanDisk Cruzer 8GB sticks, and I have the same problem with both. I have a super talent 32GB USB SSD in the neighboring port and it works at expected speeds. The problem I seem to see in the GUI is that the progress bar goes to 90% almost instantly, completes to 100% a little slower and then hangs there for 10 minutes. Interrupting the copy at this point seems to result in corruption at the tail end of the file. If I wait for it to complete the copy is successful. Any ideas? dmesg output below: [64059.432309] usb 2-1.2: new high-speed USB device number 5 using ehci_hcd [64059.526419] scsi8 : usb-storage 2-1.2:1.0 [64060.529071] scsi 8:0:0:0: Direct-Access SanDisk Cruzer 1.14 PQ: 0 ANSI: 2 [64060.530834] sd 8:0:0:0: Attached scsi generic sg4 type 0 [64060.531925] sd 8:0:0:0: [sdd] 15633408 512-byte logical blocks: (8.00 GB/7.45 GiB) [64060.533419] sd 8:0:0:0: [sdd] Write Protect is off [64060.533428] sd 8:0:0:0: [sdd] Mode Sense: 03 00 00 00 [64060.534319] sd 8:0:0:0: [sdd] No Caching mode page present [64060.534327] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.537988] sd 8:0:0:0: [sdd] No Caching mode page present [64060.537995] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.541290] sdd: sdd1 [64060.544617] sd 8:0:0:0: [sdd] No Caching mode page present [64060.544619] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.544621] sd 8:0:0:0: [sdd] Attached SCSI removable disk

• Word 2007 "Out of Memory or Disk Space" Error on launch.

  - by Adam

  Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

• I can't program because the code I am using uses old coding styles. Is this normal to programmers? [closed]

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: Does not have comments Does not have functions (50, 100, 200, 300 or more lines executed in sequence) Uses a lot of if statements with a lot of paths Has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) Uses an old language (Visual FoxPro 8 from 2002), but there are new releases from 2007. I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way? EDIT: All the answers are very good. For my (un)hope, appears that there are a lot of this kind of code bases around the world. A point mentioned to all answers is refactor the code. Yeah, I really like to do it. In my personal project, I always do this, but... I can't refactor the code. Programmers are only allowed to change the files in the task that they are designed for. Every change in old code must be keep commented in the code (even with Subversion as version control), plus meta informations (date, programmer, task) related to that change (this became a mess, there are code with 3 used lines and 50 old lines commented). I'm thinking that is not only a code problem, but a management of software development problem.

• Groovy Grapes in NetBeans IDE

  - by Geertjan

  The start of Groovy Grapes support in NetBeans IDE. Below you see a pure Groovy project, with the Groovy JAR and the Ivy JAR automatically on its classpath. There's also a Groovy script that makes use of a @Grab annotation. In the bottom left, in the Services window, you also see a Grape Repository browser, i.e., showing you the JARs that are currently in ".groovy/grapes". Click the images below to get a better look at them. Next, you see what happens when the project is run. The @Grab annotation automatically starts downloading the JARs that are needed and puts them into the ".groovy/grapes" folder. However, the "no suitable classloader found for grab" error message (which Google shows is a problem for lots of developers) prevents the application from running successfully: The final screenshot shows that I've put the JARs that I need onto the classpath of the project. I did that manually, hoping to learn from the NetBeans Maven project or the NetBeans Gradle project how to do that automatically. Also note that the @Grab annotation has been commented out. Now the error message about the classloader is avoided and the project runs. What needs to happen for Groovy Grapes support to be complete in NetBeans IDE: Figure out how to add the downloaded JARs to the project classpath automatically. Fix the refresh problem in the Grape Repository browser, i.e., right now the refresh doesn't happen automatically yet. Hopefully find a way to get around the grab classloader problem, i.e., it's not ideal that one needs to comment out the annotation. Let the user specify a different Grape repository, i.e., right now ".groovy/grapes" is assumed, but the user should be able to point the repository browser to something different. Maybe there should be support for multiple Grape repositories? Comments/feedback/help is welcome.

• Time machine folders won't restore recursively

  - by Brian Postow

  I have a Snow Leopard system with Time Machine. Every so often I need to look at an old folder, so I go in and try to restore it, usually to a different location. What I end up with is an empty folder of the appropriate name. none of the files, nothing. It doesn't give any error messages. The files ARE there, because I can see them, also, if I go in via the mount point, and trace down through the file system, I can do a filecopy of the folder, and everything turns out fine. However, that seems like a bad idea. so, I'd like to know why he "right" way doesn't work... I believe that it used to work. It's also possible that it only doesn't work for certain folders. I haven't tested extensively.

• RAID 1 after install and two controlers

  - by jfreak53

  I have question regarding RAID 1. Can I setup software RAID 1 after having installed the first drive and setup ubuntu 12? I know that during server install and partitioning I can select RAID and setup then, but what I am not clear on is how in the world to setup RAID 1 after the fact? Can someone provide directions for this? Also, can I RAID 1 two drives one being 500GB and the mirror drive being 1TB? Of course the mirror drive would have a 500GB partition but that's my point. Lastly, can one drive be on IDE and the other on a SATA controller? I know speed will be an issue, that doesn't matter, I just need to know if it will work without corrupting data and if it's the same process? Thanks.

• variables in batch scripts [closed]

  - by richzilla

  I'm trying to set up a batch file to automatically deploy a php app to a web server. Basically, what I want is an entirely automated process: I would just give it a revision number from the repository and it would then export the files, upload via ftp and then update deployment info at the repo host (codebase). However, I'm starting from scratch here. How would I set up a batch file to accept a variable when it was run? For example, the command myfile.bat /revision 42 should deploy revision 42 to my server. If anyone can point me in the right direction I'd appreciate it.

• Why is ext3 so slow to delete large files?

  - by Janis Peisenieks

  I have a server, which makes an incremental backup of a system every night. Now on saturdays, there is a full backup. But after the full backup has finished, a script kicks in, that deletes the incrementals. Now, the script sometimes breaks, and it is because the incrementals are each about 10GB files, and sometimes takes too long for the script. Now could someone explain to me, or point me in the direction of a resource, that explains why ext3 is so slow to delete files, when compared to, lets say, NTFS? I know theses are 2 completely different file systems, but I'm really interested why is there such a big difference in deletion?

• Subdomain redirect to WWW

  - by manix

  I have the domain example.com and the test.example.com running on apache server. For some reason when I try to visit test.example it is redirected to www.test.example and by consequence a Server not found error is displayed in the browser. Both .htaccess (root and subdomain folder) files are empty. Additional facts I have another subdomain xyz.example.com pointed to public_html/xyz directory with some content inside (index.html with "hello world message") and it works fine if I use xyz.example.com instead of www.xyz.example.com. So, can you help me to point to the right direction in order. I have a vps and I am able to change any file if is required. Below you can find my virtual host configuration. <VirtualHost xx.xxx.xxx:80> ServerName test.example.com ServerAlias www.test.example.com DocumentRoot /home/example/public_html/test ServerAdmin [email protected] UseCanonicalName Off CustomLog /usr/local/apache/domlogs/test.example.com combined CustomLog /usr/local/apache/domlogs/test.example.com-bytes_log "%{%s}t %I .\n%{%s}t %O ."

• OWA no longer accessing 1 backend exchange server

  - by Morchuboo

  We have IIS hosting OWA that is the web frontend to 3 backend exchange servers. Yesterday we got a lot of event 9791 warnings: "Cleanup of the DeliveredTo table for database 'Second Storage Group\Mailbox Store EUROPE 2' was pre-empted because the database engine's version store was growing too large. 0 entries were purged. At this point the server was crawling. Our Mail admin is currently away and not contactable so we rebooted the server. Everything seems ok when reading mail from outlook and evolution-mapi clients but OWA and active-sync connections cannot access. When logging into OWA, users whos mailboxes are not on this backend server are fine but users on this server can log into the OWA frontend but once submitting their credentials the page returns a 503 service unavailable error. We have since rebstarted the affected exchange server and the IIS server as well as iisreset /noforce but problem persists. Can anyone suggest what we should look at...

• Bending of track in a racing game

  - by caius

  I am trying to create a small racing game in which the track would be modeled using a BSpline curve for the path's center line and directional vectors to define the 'bending' of the track at each point. My problem is that I don't know how to calculate the correct bending / slope of the curve, in such a way that it would be optimal or at least visually nice for a car to 'bend in the corner'. My idea was to use the direction of the 2nd derivatives of the curve, however while this approach looks fine for most of the track, there are points in which the 2nd derivative makes sharp 'twists' / very quick 180 degree flips. I also read about 'knots' of bsplines, but I don't know if such 'twist' in 2nd derivatives is a knot or knots are something else. Can you tell me that using a BSpline: 1. How could I calculate a visually nice bending of a track for a racing game? 2. Is it possible to do this by using some simple calculations of centripertal force / gravity? 3. Is it possible to do this by using 1st, 2nd and 3rd derivatives of the BSpline curve? I am not looking for the 'physically correct' bending angle for the track, I would just like to create something which is visually pleasing in a simple game. I am using a framework which has a built-in class for BSpline, including support for 1st, 2nd and 3rd derivatives of the curve.

• Is it safe to operate a laptop without battery?

  - by leladax

  I know it's 'unsafe' in terms of data loss but I noticed motherboards still have some of their circuits on power when they are plugged in [e.g. a circuit that must wait for power-on signals is certainly one of them]. Hence, I wondered if it would increase the life of the laptop if the battery was simply off. Let alone that may also increase battery life, but that's the least of my concerns. Notice the main point is to plug it off on hibernate and have no power source whatsoever for the duration of being off (apart from the clock battery). (i.e. saving having to plug off the battery every time)

• Sound does not play when locking WinXP

  - by Christopher

  If I press the Windows-L combination to lock my PC the "Windows Logoff" sound does not play. It used to but at some point it stopped. I installed only trustworthy apps on my system and it is pretty clean so I don't think it is a virus. I checked the sounds in the control panel and "Windows Logoff" is set. Is there a sound associated with the key combination? Perhaps something in the registry? Any help is appreciated.

• Is it possible to sync specific router settings across multiple routers?

  - by Betard Fooser

  I recently purchased a second Linksys wireless routers set up on the other side of my home and I am wondering if it is possible to somehow sync particular settings between the two? For instance what I am really after is the "MAC Filter List". I would "like" to be able to maintain the list on both routers without having to manually type in the field values. maybe this isn't possible, or has an easy answer, but hopefully those of you who know will cut me a bit of slack. I tried to "google" the answer to this of course, but it seems any searches with the words "sync" and "router" and/or "wifi" result in pages of people having issues with synching their iOS devices over wifi. I would say that have decent amount of networking knowledge in regards to average home networks, and I imagine in larger businesses / corporations they must have a "simpler" way of maintaining things like this. Any insight to point me in the right direction will be much appreciated.

• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• Accessing Secure Web Services from ADF Mobile

  - by Shay Shmeltzer

  Most of the enterprise Web services you'll access are going to be secured - meaning they'll require you to pass a user/password in order to get to their data.  If you never created a secured Web service, it's simple in JDeveloper! For the below video I just right clicked on a Java class that I exposed as a Web service, and chose  "Web Service Properties" and then checked the "oracle/wss_username_token_service_policy" box from the list of options (that's the option supported by ADF Mobile right now): In the demo below we are going to use a "remote" login server that does the authentication of the user/pass.The easiest way to "create" a remote login server is to create a "regular" web ADF application, secure it, and deploy it on a server. The secured ADF application can just require ADF Authentication with a simple HTTP Basic Authentication - basically the next two images in the Application->Secure->Configure ADF Security menu wizard. ok - so now you have a secured ADF application - deploy it on a server and get the URL for that application.  From this point on you'll see the process in the video which deals with the configuration of your ADF Mobile app. First you'll need to enable security for your ADF mobile application, so it will prompt users to provide a user/pass combination. You'll also need to configure security on specific features. And you can have them use remote login pointing to your regular secured ADF application. Next define your Web service data control. Right click on the web service data control to "define Web Service Security". You'll also need to define the adfCredentialStoreKey property for the Web Service data control in the connections.xml file. This should be it. Here is the flow: If you haven't already - you can read more about this in the Mobile developer guide, and Andrejus has a sample for you.

• Trouble with Collada bones

  - by KyleT

  I have a Collada file with a rigged mesh. I've read the node tags in the library_visual_scenes tag and extracted the matrix for each node and stored everything in a hierarchical bone structure. My Matrix container is "row major", so I'd store the first float of a matrix tag in the 1st row, 1st column, the second in the 1st row, 2nd column, etc. From what I gather this is the Bind Pose Matrix. After that I went through the tag and extracted the float array in the source tag of the skin tag of the controller for the mesh. I stored each matrix from this float array in their corresponding Bone as the Inverse Bind Matrix. I also extracted the bind-shape-matrix and stored it. Now I'd like to draw the skeleton with OpenGL to see if everything is working correctly before I go about skinning. I iterate once over my bones and multiply a bone's Bind Pose Matrix by it's parents and store that. After that I iterate again over the bones and multiply the result of the previous matrix multiplication by the Inverse Bind Matrix and then by the Bind Shape Matrix. The results look something like this: [0.2, 9.2, 5.8, 1.2 ] [4.6, -3.3, -0.2, -0.1 ] [-1.8, 0.2, -4.2, -3.9 ] [0, 0, 0, 1 ] I've had to go to various sources to get the little understanding of Collada I have and books about 3d transform matricies can get pretty intense. I've hit a brick wall and if you could please read through this and see if there is something I'm doing wrong, and how I'd go about getting an X,Y,Z to draw a point for each of these joints once I've calculated the final transform, I'd really appreciate it.

• SCO Unix - finding and pulling data

  - by lxlxlxl

  We recently acquired a company that was running a legacy application on a SCO Unix box. I can tell that the app is running off of http, but its reporting and data export functions are limited and I'd like to find a master db or data source on the box that maybe I can migrate into something more useful. Any ideas how I could possibly find that? Would there be something in apache or startup scripts that might point to a master db? do Unix applications have standard data source locations? I'm not sure if I'm wording this right so apologies in advance.

• Small business VPN solution

  I've been looking for a while but I'd like to to implement a vpn solution for anywhere from 1-5 employees at a time (possibly 10 in a year or so) edit: Basically I would like outside users to fire up a client or open a web page and be able to access things inside the company network (share drives / printers/ webapps /etc) I've looked at Astaro Gateway but im not sure if that's the right tool for the job. I know "best" is a subjective term so i would like to break it into to different suggestions 1) what is the cheapest solution given the criteria above 2) what solution will result in the least amount of headaches from the point of view of maintenance and learning curve.

• Having the same texture data in different ID3D11Texture2D

  - by bdmnd

  Sorry if this has been answered elsewhere - I'm rather new to DX. My question concerns conservation of resources - specifically textures in VRAM. I assume that upon returning from a call to CreateTexture2D, a copy of any textures data supplied has been copied elsewhere, likely VRAM. Does DX11 have any facility for having multiple ID3D11Texture2D objects which point to the same data? This might at first seem silly, but imagine a ID3D11Texture2D which is an array of textures. In one material, an artist has chosen to blend three identically sized maps, saved on disk as A.dds, B.dds, and C.dds. Then imagine they have another material which also uses three maps, but this time A.dds, B.dds, and D.dds. The shader code knows the diffuse texture is a texture array, and also has the number of layers baked (three in each case). I would essentially like to set up just two ID3D11Texture2D objects, one for each material, but I don't want to waste VRAM for two identical copies of A.dds and B.dds. I could use explicit texture arrays, of course, but this reduces the number of resources available to the shader and can complicate code somewhat more than would otherwise be needed.

• Ubuntu doesn't start and I can't login [migrated]

  - by Meph00

  My ubuntu 13.04 doesn't boot anymore. Eternal black screen. If I press ALT+CTRL+F1 I see that it's stucked on "Checking battery state [OK]." I'd like to try to go with sudo apt-get install gdm but I can't login on terminal tty2, tty3 etc. They correctly ask for my nickname, then they make me wait a lot, ask for password and make me wait again. After a lot of time (... a lot) the best I could achieve was visualizing "Documentantion https://help.ubuntu.com". I can never reach the point where I can give commands. Plus, during the long pauses, every 2 minutes it gives a messagge like this: INFO: task XXX blocked for more than 120 seconds. Any suggestion? Sorry for my bad english and thanks everyone for the attention.

• Getting rank for keywords that I don't want to appear on my website [duplicate]

  - by Rober

  This question already has an answer here: Which keyword should I use. colors or colours or a combination of both? 2 answers One of my products has two names. One of them is what I consider correct and thus it is what I want to appear on my website. The other name is incorrect for me, so I would like to avoid it. But I know that many people will search my product using the "bad" name. How could I get the "bad" name indexed for my site on search engines even if nobody can read it there? Of course, I want to do it "legally" so that no engine will ban my site considering it as cloaking, black hat SEO, etc... EDIT: Having that "bad" name on my backlinks is not an option. For example I would perceive user reviews connecting my site to that word as a negative point. Maybe having my site as a search result for that word could be negative as well, but I think it is worth it.

• Virtual MS Sql Server not consuming enough CPU

  - by rocketman

  We have a Win2008 server 32 bit running as a virtual machine under ESX server. It has 6 CPU cores of 2Gz each and 4GB ram. It's running MS Sql Server 2008 R2 only. Problem: The server is heavily loaded and responds slowly. From windows taskmanagers point of view, it really looks overloaded, CPU wise. However, our external "cloud manager" says it's only using 2.5GHz worth of CPU-cycles in the cluster. I/O times looks "good". We have already tried to set the SQL servers number of working threads from 0(auto) to 256, to no effect. How to tune the VM host, guest or SQL to use all of it's alotted resources? Does it sound possible att all?

• Impact Earth Lets You Simulate Asteroid Impacts

  - by Jason Fitzpatrick

  If you’re looking for a little morbid simulation to cap off your Friday afternoon, this interactive asteroid impact simulator makes it easy to the results of asteroid impacts big and small. The simulator is the result of a collaboration between Purdue University and the Imperial College of London. You can adjust the size, density, impact angle, and impact velocity of the asteroid as well as change the target from water to land. The only feature missing is the ability to select a specific location as the point of impact (if you want to know what a direct strike to Paris would yield, for example, you’ll have to do your own layering). Once you plug all that information in, you’re treated to a little 3D animation as the simulator crunches the numbers. After it finishes you’ll see a breakdown of a variety of effects including the size of the crater, the energy of the impact, seismic effects, and more. Hit up the link below to take it for a spin.

• How do I establish the network sharing to my WinXP server network drive from my Mac notebook?

  - by mobibob

  I have been able to connect to my WinXP server's shared drives by using Finder's Command-K to browse the network. Unfortunately, when the server gets rebooted, the connection drops and sometimes I cannot get reconnected. I have specified different protocols (afp / cifs / smb) and different login names (connect as...) with limited success. Once I find the right combination, I am good for a few weeks. Once, it seems as though I had to unshared and shared the drive to get it to work. Unfortunately, it is very frustrating, so I try multiple things at one time, so when I finally get to the success point -- I honestly don't know what worked. I followed Mac help, surfed for instructions, issues, etc., but nothing appears to be consistent. I would love for this thread to be the ultimate answer for all time! Can anyone help me? If my description or question need more detail, please ask away!
