• Switching to Chrome from IE

  - by Alan Parrish

  Hi, I work in IT at a school and we recently updated our database software, however the web access that the teachers use to do registration does not work too well with Internet Explorer 7 and we're thinking about switching to chrome (mostly due to me hating IE in general) but the problem we have is that users are unable to migrate their bookmarks over from IE due to account restrictions, is there any way to get this working? A bit of info about the system if it could be helpful; Almost all the client PCs are running Win XP SP2. My colleagues machines are running Windows 7, I use OS X Snow Leopard and most of out servers are running windows server 2003 (with the exception of 2 one on 2000 server and another on 2008 R2). The Active Directory Controller is running Windows Server 2003

• Problems with ATI propietary driver in Ubuntu 12.10, window trail and screen does not update

  - by crystallero

  I have problems with the Ati propietary driver (fglrx). I have an iMac (mid 2011) with a Radeon HD 6900M [1002:6720]. I did not have any problem under Ubuntu 12.04, but since I updated to 12.10, I get some annoying graphic corruption. The worst one is that sometimes the screen does not update with the new information. It happens a lot when I change between tabs in Chrome or Sublime Text. It usually gets updated when I scroll the page. Sometimes, when I type, I have to wait a little bit to view the new characters. And I get trails when I move windows too (like a part of the window). After a while, the trail disappears. I tried to install fglrx, fglrx-updates and the new beta driver downloaded from Ati (12.11 Beta 11/16/2012), with no luck. It happens the same with all of them. I tried to mess with Compiz config, but it didn't fix anything. The open source driver does not suffer this problem, but I need the performance of the propietary driver . Do you have clue? Thanks.

• Add users in Windows machine without AD

  - by guillem

  I have several development machines where I am the administrator. We are using AD in my organization but is maintained by and offshore IT group any request takes a long time. We are currently granting access to developers on development machines manually so it's a bit annoying to maintain although at least it's fast. We have also a lot of external consultants that need to use those machines for some time. Is there any tool or method to maintain a set of users synced on those machines without the need add them to an AD group?

• Returning a flexible datatype from a C++ function

  - by GavinH

  I'm developing for a legacy C++ application which uses ODBC for it's data access. Coming from a C# background, I really miss the ADO style of data access. I'm writing a wrapper (because we can't actually use ADO) to make our data access less painful. This means no char arrays, no manual text blob streaming, and no declaritive column binding. I'm struggling with how to store / return data values. In C# at least, you can declare an object and cast it to whatever (as long as the type is convertable). My current C++ solution is to use boost::any to store the data value in a custom DataColumnValue object. This class has conversion and assignment operators to the various types used in our app (more than 10). There's a bit of complexity here because if you store an int in the boost::any and try to boost::any_cast<long> you get a boost::bad_any_cast. Client objects shouldn't have to know how the value is stored internally. Does anyone have any experience trying to store / return values whose types are only known at runtime? Is there a better / cleaner way?

• Cherokee high virtual memory usage even after disabling I/O Cache

  - by nidheeshdas

  hi all I've Ubuntu 10.04LTS 64-bit running on a openvz container and Cherokee 1.0.8 compiled from source. The virtual memory usage of cherokee-worker is around 430 MB even after disabling I/O cache from Advanced - I/O Cache - NOT enabled. Is this issue particular to openvz? Because many people reported to have successfully reduced virt memory usage by disabling io cache. htop output: http://imgur.com/z5JEL.jpg (newbies not allowed to post image.) thanks in advance. nidheeshdas

• How should a small team using multiple OS's deploy over github?

  - by Toby

  We have a small development team that have recently moved to using github to host our projects. The team consists of three developers, 2 on Windows and 1 on Mac. I am currently researching the best way to deploy applications to our Linux servers (dev and production). Capistrano running locally would be ideal but from what I read this won't work for Windows machines. It looks like the best way is to use a post-receive hook in github, I can see how this would work for auto deploying to dev, but I don't see how we could then deploy to live. I have found paid projects like http://www.deployhq.com/ but it feels like something that a quick bit of code should be able to do for free, I just can't seem to get myself pointed in the right direction! I was wondering what would be considered best practice for small team deployment involving multiple local OS's and github.

• Excel Single column into rows, VBA script insight

  - by Sanityvoid

  Okay, so much similiar to the below link but mine is a bit different. Paginate Rows into Columns in Excel I have a lot of data in column A, I want to take every 14 to 15 rows and make them a new row with multiple columns. I'm trying to get it into a format where SQL can intake the data. I figured the best way was to get them into rows then make a CSV with the data. So it would like like below: (wow, the format totally didn't stick when posting) column A column B C D etc 1 1 2 3 x 2 16 17 a b 3 x y z 15 16 17 a b c I can clarify if needed, but I'm stumped on how to get the data out of the single column with so many rows in the column. Thanks for the help!!!

• How do I transfer videos from DV camera to divx?

  - by Ward

  I have a videocamera that uses mini-dv tapes. In the past, I've transferred the files and made DVDs, but that was time- and disk-space- consuming. I wanted to find new tools and to figure out how to convert the videos to something smaller like divx but I didn't know enough about all the different formats to answer a previous question. Well, now I've done a bunch of research and I understand some of the details of video encoding, and in the process I wrote up some notes on the different formats involved in going from a DV videocam to divx or H.264 They're a bit rambling, but in case it's of any use, I'm going to post them as an answer. I'd be very interested in anyone else's answer as well.

• XAMPP on windows 7 not working

  - by 404Error

  Hey there, I just installed XAMPP lite on Windows 7. I have two drives - C: for the OS and regular files, and an external drive E:. I insatlled XAMPP lite on E: (on the root), and its been giving me problems. Apache works well enough, but MySQL doesn't work. When I go to http://localhost/phpmyadmin/, it gives me the following error: Error MySQL said: #2003 - Can't connect to MySQL server on 'localhost' (10061) Connection for controluser as defined in your configuration failed. Any ideas as to what could be the problem? I used the zip file for XAMPP lite, the 32 bit version. This is on Windows 7 Home premium. Thanks!

• Unable to SSH into ESXi 4.1 host - "Access Denied"

  - by Andrew White

  I am unable to SSH into an existing ESXi server. I have a user which is in the "root" and "users" group and is able to connect via vSphere. However after enabling "Remote support (SSH)", attempting to connect by putty and entering my username/password when prompted I am presented with an "Access Denied" message. I have run through the options presented at this KB article to no avail. I have taken down the firewall on the machine (it is remote) temporarily to check if this helped - no change. The username/password are definitely correct and I can obviously get connectivity if I am presented with the username/password prompt. I am at a bit of a loss what else I can try. Thanks all

• Automatic switching between monitor configurations

  - by Michael Aquilina

  I have a laptop and an external monitor and i was wondering if there was a simple approach to switching between multiple monitor configurations based on the detected available displays. For example: When i am at home and i plug in my external monitor i would like this to automatically become enabled and the laptop screen to become disabled. As soon as i pull out the display cable for the external monitor, i would like the laptop screen to automatically become enabled. I was expecting this to just "work" just like it does in windows - but it seems to be much harder than that. I am aware of the xrandr command to turn displays on and off but i cannot seem to find a way to get this to work the way i describe above. I had also found this post about switching between multiple monitor configurations and the results seem a bit inconclusive. However i was hoping that with xrandr there would be a simpler solution. For me, the fact that when i pull out my external monitor the screen just goes black and i get an error message is a big issue holding me back from making the complete switch to linux as i move around alot as a student. My OS of choice is currently Kubuntu 12.04 but i am willing to change to something else if it provides a better way of setting up the described setup.

• How do I set up my home server to go directly to a port other than 80

  - by Kevin

  I'm using dyndns, a lynksis wt54g router, and tomcat 7 with spring to set up a web server. This is my first time to attempt this. I'm sure this is a very common question, but I don't know enough to find the answer after quite a bit searching. Dyndns is successfully forwarding to my ip. The main problem is, the router admin login is coming up when my url is used. I'm hosting my site on port 8080. I have port forwarding set up for port 8080 but my request times out when I attempt to use my url like this www.myurl1234.com:8080. I don't want users to have to type the port anyway. I also tried changing the management port to 82 and hosting on port 80, but I still get the router admin login when I use my url. Where am I going wrong? Can I set it up so that www.myurl1234.com goes straight to port 8080?

• Poor TCP loopback throughput on Windows

  - by Yodan Tauber

  I measured the throughput of a locally bound TCP socket connection on my computer (Intel Q9550, 64 GB RAM, Windows XP 64 bit) using iperf. I got dissatisfying results (around 1.6 Gbit/s) each time, no matter how I tweaked the TCP settings (buffer length, window size, max segment size, no delay). I got similar results when I tried netperf. Now, I understand (from sources like these) that the average throughput of a loopback connection should be around 5 Gbit/s. What could be the reasons for such poor performance?

• Is there a better way to organize my module tests that avoids an explosion of new source files?

  - by luser droog

  I've got a neat (so I thought) way of having each of my modules produce a unit-test executable if compiled with the -DTESTMODULE flag. This flag guards a main() function that can access all static data and functions in the module, without #including a C file. From the README: -- Modules -- The various modules were written and tested separately before being coupled together to achieve the necessary basic functionality. Each module retains its unit-test, its main() function, guarded by #ifdef TESTMODULE. `make test` will compile and execute all the unit tests, producing copious output, but importantly exitting with an appropriate success or failure code, so the `make test` command will fail if any of the tests fail. Module TOC __________ test obj src header structures CONSTANTS ---- --- --- --- -------------------- m m.o m.c m.h mfile mtab TABSZ s s.o s.c s.h stack STACKSEGSZ v v.o v.c v.h saverec_ f.o f.c f.h file ob ob.o ob.c ob.h object ar ar.o ar.c ar.h array st st.o st.c st.h string di di.o di.c di.h dichead dictionary nm nm.o nm.c nm.h name gc gc.o gc.c gc.h garbage collector itp itp.c itp.h context osunix.o osunix.c osunix.h unix-dependent functions It's compile by a tricky bit of makefile, m:m.c ob.h ob.o err.o $(CORE) itp.o $(OP) cc $(CFLAGS) -DTESTMODULE $(LDLIBS) -o $@ $< err.o ob.o s.o ar.o st.o v.o di.o gc.o nm.o itp.o $(OP) f.o where the module is compiled with its own C file plus every other object file except itself. But it's creating difficulties for the kindly programmer who offered to write the Autotools files for me. So the obvious way to make it "less weird" would be to bust-out all the main functions into separate source files. But, but ... Do I gotta?

• Looking for 'WinHlp32.exe compatible' replacement for free redistribution under vista and windows 7

  - by richardboon

  Our software installs a package of legacy software for the client, some of it has old hlp file from 3rd party vendor requiring winhlp32.exe (note: we have no legal right to modify the hlp). Those client may only have cd/dvd and might not have internet access, etc. So I need a free 'WinHlp32.exe compatible' replacement for our redistribution under vista and windows 7. Background of problem: -Microsoft stopped including the 32-bit Help file viewer in Windows releases beginning with Windows Vista and Windows Server 2008. -Starting with the release of Windows Vista and Windows Server 2008, third-party software developers are no longer authorized to redistribute WinHlp32.exe with their programs. http://support.microsoft.com/kb/917607

• C#, .NET 4.5 and Visual Studio 2012

  - by subodhnpushpak

  While I continue my affair with iOS / Android (which is now my bread / butter literally ); I also have managed to keep myself excited enough for all of new windows Stuff. Thanks to Priti Pushpak (my wife) for all the amazing Windows Phone 7 apps she is creating and uploading on appHub… I kind of like refreshing feel of win8 and apps. I also have fair bit of exposure on iPhone / iPad; Mac apps and I do put my two cents for win8 as well. If not an instant hit; win8 apps surely grows on you. So eventually win8 platform is here to stay. (oh yes and I cannot tell you how much hope I have for WP8 platform as well). Nevertheless; here is few topics I covered in a session on .Net 4.5  and on popular demand I am posting it all here… Note that for the demo you must have Win8 installed along with VS2012. The Demo includes a ASP .NET Web API http://www.slideshare.net/spushpak/new-features-in-net-45-c-and-vs2012 New features in .NET 4.5, C# and VS2012 from Subodh Pushpak The slide deck, demo and the session recording is at: http://sdrv.ms/R1thCf and https://www.dropbox.com/sh/0ogfayv0djfafyg/hfw5mNLaz9

• Windows Home Server restore causes computer to be removed from the domain?

  - by unknown (google)

  I restored my Dell M4400 that is a company laptop, and now I get an error when I try to log on and am connected to our corporate network, which says that the domain controller could not be found or that the computer is not part of the domain. Everyone else can log on, so it seems my computer is no longer part of the domain, even though it thinks it is per the settings. One thing of note: my computer crashed on 1/14/10, but I restored from a backup that was made on 12/20/09. So I am not sure if that made a difference? Also, I tried running "gpupdate" to update my group policy, but that did not seem to help. Any ideas? Seems like a bit of a flaw in the backup system for computers that are part of a domain. I guess I wanted to hear from someone with more knowledge about how a computer is recognized as part of a domain to know if this should be expected when doing a restore or if I should file a trouble ticket.

• How to increase the disk cache of Windows 7

  - by Mark Christiaens

  Under Windows 7 (64 bit), I'm reading through 9000 moderately sized files. In total, there is more than 200 MB of data. Using Java (JDK 1.6.21) I'm iterating over the files. The first 1400 or so go at full speed but then speed drops off to 4ms per file. It turns out that the main cost is incurred simply by opening the files. I'm opening the files using new FileInputStream (and of course closing them in time to avoid file leaks). After some investigating, I see that Windows' disk cache is using only 100 MB or so of RAM although I have 8 GiB available. I've tried increasing the cache size using the CacheSet tool but any values I provide are considered out of range. I've also tried enabling the LargeSystemCache registry key but (after rebooting) the CacheSet tool still indicates I'm using 100 MB of cache (and doesn't increase during the test run). Does anybody have any suggestions to "encourage" Windows 7 to cache my 9000 files?

• Is virtual machine slower than the underlying physical machine?

  - by Michal Illich

  This question is quite general, but most specifically I'm interested in knowing if virtual machine running Ubuntu Enterprise Cloud will be any slower than the same physical machine without any virtualization. How much (1%, 5%, 10%)? Did anyone measure performance difference of web server or db server (virtual VS physical)? If it depends on configuration, let's imagine two quad core processors, 12 GB of memory and a bunch of SSD disks, running 64-bit ubuntu enterprise server. On top of that, just 1 virtual machine allowed to use all resources available.

• RHEL 6.5 and LDAP

  - by zuboje

  I am trying to connect our Active directory server to brand new RHEL 6.5 server. I want to authenticate users using AD credentials, but I want to restrict that only certain users can login, I don't want to allow anybody from AD to connect to it. I would like to use something like this: CN=linuxtest,OU=SecurityGroups,DC=mydomain,DC=local but I am not sure how would I setup OU and CN. I use sssd for authentication and my id_provider = ad. I wanted to use id_provider = ldap, but that did not work at all and RHEL customer service told me to setup this way. But I want to have a little bit more control who can do what. I know I can use this to restrict simple_allow_users = user1, user2, but I have 400+ users, I really don't want to go and type them all. Question is how would I setup OU or CN for my search?

• Changing location in Google Chrome when searching

  - by Alex

  I've recently moved to the Czech Republic from Scotland and I can't find a way to permanently stop Google from automatically defaulting back to google.cz all the time. I've checked to ensure that all my google accounts and cookie based settings (e.g. Advanced Search Options) are set to English but it's still clearly doing an IP address lookup and disregarding everything else. The default Search Engine for Google Chrome (and switches to google.cz automatically): {google:baseURL}search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s I've tried hardcoding it to: http://www.google.com/search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s this kind of works, but won't work for inline searching, i.e. I always have to press enter in order to get any results which is a bit annoying as I've gotten so used to AJAX style searching I can't have been the only one to get this issue? Any help is appreciated

I am currently using Free SMTP Server http://www.softstack.com/freesmtp.html This software works great other than the fact that it can only send 10 messages a day. This is a bit of a problem seeing that the software I am writing needs to send a message every half hour. Anyone knows of a good piece of software that does the same thing, but does not limit the amount of messages that can be sent in a day?

We have reached stage where our environment can not handle application resulting in JBoss shut down throwing out of memory errors and CPU reaching to 90% usage. I am looking methodology to calculate correct server sizing where I input TPS, max number of concurrent users, max CPU utilization etc.. to give me number of servers, RAM size, number of cores. I am expecting application to grow 10% annually. Load Balancer and Failover should also be taken in account while sizing.
