• Synonyms for different languages in LibreOffice Writer? [closed]

  - by cipricus

  Possible Duplicate: How do I add English-UK thesaurus in LibreOffice? When setting a text for English US the context menu contains 'Synonyms' This is not the case for the other languages for which I have the spelling installed (English UK, French etc) Can I have the Synonyms option for UK English too, for example? Even that is a problem although there seems to be solutions around for it. Here, for example, (which is a link to here) but after testing it cannot see synonyms for uk. Also this which was reported as a solution is not working anymore it seems. What about other languages? (Please notice that this question is not just about English-UK. I have initially noticed that 'synonyms' where missing in relation to British, but I am asking about how to solve the issue in general or, when there is no general solution, how to solve it on a case-by-case basis. For the meta consequence of all this, involving the issue of it being a duplicate, see comments under here and this question.)

• I don't have permission to access other drives

  - by mcjohnalds45

  After messing with the user accounts & names, I found I can't access my external drives without using sudo. So when I access one normally with cd "/media/john/FreeAgent Drive" I receive bash: cd: /media/john/FreeAgent Drive: Permission denied However, using sudo: sudo cd /media/john sudo ls -l It gives: drwx------ 1 john john 20480 Sep 24 10:45 FreeAgent Drive/ And id returns uid=1003(john) gid=1003(john) groups=1003(john), ... So I'm interpreting this is as "you are john, only john can access this drive, however, you cannot access this drive." I have tried sudo chown john:john "FreeAgent Drive" and sudo chmod o+rw "john/FreeAgent Drive"but I still can't access it.

• Is the "One Description Table to rule them all" approch good?

  - by DavRob60

  Long ago, I worked (as a client) with a software which use a centralized table for it's codified element. Here, as far as I remember, how the table look like : Table_Name (PK) Field_Name (PK) Code (PK) Sort_Order Description So, instead of creating a table every time they need a codified field, they where just adding row in this table with the new Table_Name and Field_Name. I'm sometime tempted to use this pattern in some database I design, but I have resisted to this as from now, I think there's something wrong with this, but I cannot put the finger on it. It is just because you land with some of the structure logic within the Data or something else?

• ssh tunnel to a remote CUPS server

  - by drevicko

  There is a CUPS server beyond a firewall and I'd like to use it's printers. I have ssh access to computers that can access the CUPS server, and can get at the servers web interface by forwarding say port 1631. I cannot forward port 631 as I've not got root access to anything on the servers network. In Ubuntu's 'Printing' control panel, I can enter the address of a server, but I've not been able to connect through the forwarded port (localhost:1631, which is forwarded to the remote CUPS server's 631 port). Any ideas?

• Using glReadBuffer/glReadPixels returns black image instead of the actual image only on Intel cards

  - by cloudraven

  I have this piece of code glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, buffer ); Which works just perfectly in all the Nvidia and AMD GPUs I have tried, but it fails in almost every single Intel built-in video that I have tried. It actually works in a very old 945GME, but fails in all the others. Instead of getting a screenshot I am actually getting a black screen. If it helps, I am working with the Doom3 Engine, and that code is derived from the built-in screen capture code. By the way, even with the original game I cannot do screen capture on those intel devices anyway. My guess is that they are not implementing the standard correctly or something. Is there a workaround for this?

• lighttpd: why using port >= 9000 does not work properly

  - by yejinxin

  I had a lighttpd server which works normally. I can access this website from outside(non-localhost) via http://vm.aaa.com:8080. Let's just assume that it's a simple static website, without php or mysql. Now I want to copy this website as a test one(using another port) in the same machine. And I do not want to use virtual host. So I just copy the whole files of original server, including lighttpd's bin/ conf/ htdocs/ lib/ and so on folders. And I made some required change, including changing lighttpd.conf. Now what I'm confused is, if change the port to a number that is less than 9000, it works perfectly. But if the port is changed to a number that is equal or greater than 9000, lighttpd can start, but I can not access the new website from outside, while I do can access the new website from INSIDE(I mean in the same LAN or localhost). The access log from INSIDE is like below: vm.aaa.com:9876 10.46.175.117 - - [08/Oct/2012:13:18:47 +0800] "GET / HTTP/1.1" 200 15 "-" " curl/7.12.1 (x86_64-redhat-linux-gnu) libcurl/7.12.1 OpenSSL/0.9.7a zlib/1.2.1.2 libidn/0.5.6" Command I used to start lighttpd is: bin/lighttpd -f conf/lighttpd.conf -m lib/ -D My lighttpd.conf is like: server.modules = ( "mod_access", "mod_accesslog", ) var.rundir = "/home/work/lighttpd_9876" server.port = 9876 server.bind = "0.0.0.0" server.pid-file = var.rundir + "/log/lighttpd.pid" server.document-root = var.rundir + "/htdocs/" var.cronolog_path = "/home/work/lighttpd_9876/cronolog/sbin/cronolog" server.errorlog = ... accesslog.filename = ... ... So why is this happening? I've tried several diffrent ports, still the same. Isn't that ports between 8000 and 65535 are the same?

• How to set up offline manifest for a web app to run in Safari in iOS?

  - by ahmd1

  I'm currently trying to set up an offline.manifest file for my web app to be used offline on an iOS device. For testing purposes I have a very simple HTML page that I'm trying to add to a home screen. I'm testing it on a live iPhone 4, but after the page is added to the home screen and I put the iPhone in the airplane mode and try to start my web app I get this error: "Turn Off Airplane Mode or Use Wi-Fi to Access Data" and then if I click OK I get: "Cannot Open Web App Name" "Web App Name could not be opened because it is not connected to the Internet" The following is added to the HTML file: <!DOCTYPE html> <html lang="en" manifest="scrts/offline.manifest"> and the offline.manifest is composed as such: CACHE MANIFEST ../pics/bkgnd_iphn_settings.png ../pics/mbl_btn_fb.png ../pics/mbl_btn_twt.png ../pics/icon_57_57_bg.png ../pics/icon_72_72_bg.png ../pics/icon_114_114_bg.png ../pics/icon_144_144_bg.png ../pics/splash_320_460_bg.png ../pics/splash_768_1004_bg.png ../pics/splash_1004_768_bg.png I got all instructions on composing it from here I also adjusted the .htaccess file to add this line: AddType text/cache-manifest .manifest Any idea what am I not doing right?

• Proxied calls not working as expected

  - by AndyH

  I have been modifying an application to have a cleaner client/server split to allow for load splitting and resource sharing etc. Everything is written to an interface so it was easy to add a remoting layer to the interface using a proxy. Everything worked fine. The next phase was to add a caching layer to the interface and again this worked fine and speed was improved but not as much as I would have expected. On inspection it became very clear what was going on. I feel sure that this behavior has been seen many times before and there is probably a design pattern to solve the problem but it eludes me and I'm not even sure how to describe it. It is easiest explained with an example. Let's imagine the interface is interface IMyCode { List<IThing> getLots( List<String> ); IThing getOne( String id ); } The getLots() method calls getOne() and fills up the list before returning. The interface is implemented at the client which is proxied to a remoting client which then calls the remoting server which in turn calls the implementation at the server. At the client and the server layers there is also a cache. So we have :- Client interface | Client cache | Remote client | Remote server | Server cache | Server interface If we call getOne("A") at the client interface, the call is passed to the client cache which faults. This then calls the remote client which passes the call to the remote server. This then calls the server cache which also faults and so the call is eventually passed to the server interface which actually gets the IThing. In turn the server cache is filled and finally the client cache also. If getOne("A") is again called at the client interface the client cache has the data and it gets returned immediately. If a second client called getOne("B") it would fill the server cache with "B" as well as it's own client cache. Then, when the first client calls getOne("B") the client cache faults but the server cache has the data. This is all as one would expect and works well. Now lets call getLots( [ "C", "D" ] ). This works as you would expect by calling getOne() twice but there is a subtlety here. The call to getLots() cannot directly make use of the cache. Therefore the sequence is to call the client interface which in turn calls the remote client, then the remote server and eventually the server interface. This then calls getOne() to fill the list before returning. The problem is that the getOne() calls are being satisfied at the server when ideally they should be satisfied at the client. If you imagine that the client/server link is really slow then it becomes clear why the client call is more efficient than the server call once the client cache has the data. This example is contrived to illustrate the point. The more general problem is that you cannot just keep adding proxied layers to an interface and expect it to work as you would imagine. As soon as the call goes 'through' the proxy any subsequent calls are on the proxied side rather than 'self' side. Have I failed to learn or not learned something correctly? All this is implemented in Java and I haven't used EJBs. It seems that the example may be confusing. The problem is nothing to do with cache efficiencies. It is more to do with an illusion created by the use of proxies or AOP techniques in general. When you have an object whose class implements an interface there is an assumption that a call on that object might make further calls on that same object. For example, public String getInternalString() { return InetAddress.getLocalHost().toString(); } public String getString() { return getInternalString(); } If you get an object and call getString() the result depends where the code is running. If you add a remoting proxy to the class then the result could be different for calls to getString() and getInternalString() on the same object. This is because the initial call gets 'deproxied' before the actual method is called. I find this not only confusing but I wonder how I can control this behavior especially as the use of the proxy may be by a third party. The concept is fine but the practice is certainly not what I expected. Have I missed the point somewhere?

• I'm tempted to include easter eggs in my code - will this get me fired?

  - by blueberryfields

  While working on a portion of the code for our application, I've noticed an opportunity to include one of my side projects as an easter egg. I can do this in a way which I am certain will in no way harm anyone, and I've met with a significant and representative sample of our client base - I'm certain that those who have the knowledge and skills required to find the egg, will also find it humorous. How likely is it that I will get fired for including an easter egg in our application? For more context, the application is aimed at enterprise clients, and, while the users of it tend to be technical, geeky and will enjoy the egg, those in charge of purchasing are on the sales/marketing side of things. I can't even begin to guess how they would react. Edit: Yes, I've asked my manager. As you might expect in a corporate environment, the answer was: "I cannot condone this. You're on your own"

• 3D architecture app for Android or iPhone

  - by Manixate

  I want to make an app for 3D modeling on iPhone/Android. I cannot get the basic idea of how to get started. I have various options such as learning OpenGL ES, UDK or Unity3d but I want to create models(e.g architecture etc) in my app and then render them when user is finished modeling. I do not know if I am able to design models and then render them in the same app with various effects on the iPhone/Android using UDK or Unity3d. (Note: If you find this question unclear please ask, I may have skipped some vital information).

• To mount NAS on a Laptop?

  - by deckoff

  So, I bought a NAS, which I configured successfully in /etc/fstab, on mu Kubuntu 10.10 Thinkpad x40. It works just fine when I am at home. A few days I went out with my laptop and the problem is, that when not at home, both suspend and hibernate functions seem forever to work. I commented out the entry on fstab and the laptop started to work as expected. I played with autofs, but it seems just dies at one moment and I cannot access anything. It works for some time, and then just goes off. Is there any consistent way, to make my laptop access the drive when at home and work OK when away? Probably a script that runs at startup, checks if the mount is there and mounts it if available... or a script that umount the drive at suspend|hibernate and loads it back at startup. Any useful ideas?

• Is it a good idea to simplify an character -driven game engine to the point it's unnecessary to learn scripting/programming ?

  - by jokoon

  I remember, and I still think, that one cannot even make a prototyped 3D game to test just simple behaviors without using gigantic tools like unity or knowing extensive C++ programming, design pattern, a decent or basic 3D engine, etc. Now I'm wondering, since I know programming, that I'm still more lucky that the ones who need to learn programming prior to know how to make something: even scripted engines such as unity are not for kids, and to my sense they tend to dictate their ways of doing things, which is not the case with engine like ogre or irrlicht. I remember toying a little with the blender game engine, it was possible to link states or something I don't remember very well. Now I'm thinking that character driven games occupies a big part of the game market. Do you think it is a good idea to make a character-controlled oriented game engine which allows only to build AI instead of anything else ?

• Forward to other domain with CNAME

  - by xybrek

  In my GoDaddy DNS manager, I made some A Record that points to *.mirror for my domain Now when I access URL 123.mirror.mydomain.com from the browser I can see that my app is loaded, and its all OK. My problem now is when doing a CNAME point to the URL above on another domain like this: Accessing 123.otherdomain.com which I expect to "forward to" 123.mirror.mydomain.com I only get this 404 error: The IP 173.194.71.121 is actually ghs.googlehosted.com What I am missing here? Why 123.otherdomain.com which points to 123.mirror.mydomain.com cannot open that page and I think google is handing the web page request?

• Can't export Blender model for use in jMonkeyEngine SDK

  - by Nathan Sabruka

  I have a scene rendered in blender called "civ1.blend" which contains multiple materials (for example, I have one called "white"). I want to use this model in jMonkeyEngine, so I used the OGRE exporter to create .scene and .material files. This gives me, for example, a civ1.scene file and a white.material file.However, when I then try to import civ1.scene into the jMonkeyEngine SDK, I get an error along the lines of "Cannot find material file 'civ1.material'". Like I said, I have a white.material file, but I do not have a civ1.material file. Did anyone encounter this problem? How do I fix this?

• Computer Lab School for Orphans

  - by Brendon

  I am helping out an NGO, called Orphans Found Fund, here in Arusha Tanzania setup a computer lab to teach students about Ubuntu and open source applications. I have installed Ubuntu 10.10 on all the systems. What I'm wondering about is how to tweak the systems so that the kids cannot: Delete or alter system files Alter the system settings Add or remove applications Exceed a time limit (like an Internet Cafe) Also as the administrator I would like to monitor the usage for another system to make sure that abuse of network is not taking place. Any advice is much appreciated. Brendon

• Can't get Past Login Screen -Graphics Drivers 12.10

  - by mchangun

  Newbie Linux user here. I just installed Ubuntu 12.10, dual booting with Windows 8 Preview Release Build 8400 on a Dell Precision 490 workstation with Nvidia Quandro NVS 55/280 PCI graphics card. I cannot login to Ubuntu - after entering my password and pressing enter, the screen graphics gets garbled for a few seconds, and then the screen goes black showing only the mouse cursor. I suspect it's something to do with my Graphics Card, everything on the GUI login screen feels very sluggish. I know what I have provided here doesn't give you much information, would appreciate it if I could get some guidance on how to provide more useful logs. Thank you.

• Periodic updates of an object in Unity

  - by Blue

  I'm trying to make a collider appear every 1 second. But I can't get the code right. I tried enabling the collider in the Update function and putting a yield to make it update every second or so. But it's not working (it gives me an error: Update() cannot be a coroutine.) How would I fix this? Would I need a timer system to toggle the collider? var waitTime : float = 1; var trigger : boolean = false; function Update () { if(!trigger){ collider.enabled = false; yield WaitForSeconds(waitTime); } if(trigger){ collider.enabled = true; yield WaitForSeconds(waitTime); } } }

• Wow, no words enough for my disappointment

  - by Kevin Shyr

  Really cannot describe the disappointment felt at this moment.  A month ago there was rumor out there saying Surface tablet will be around $200.  Even though everybody agreed at the time that's not possible, or fair to Microsoft partners, the expectation was set.According to Paul Thurrott (http://www.winsupersite.com/article/windows8/microsoft-surface-pricing-availability-144526), the tablet starts at $499, but without the keyboard cover (Seriously, this is like offering Lincoln with manual shift).  The more disappointed fact is that there is no version that comes with cellular capability.  I was debating whether to get one, but now that decision is very easy.I'll wait.

• Unix as opposed to Windows (Java and C++)

  - by user997112

  Firstly I should explain the background. I am interested in high frequency trading programming roles. After looking at many job specs it is very clear that there is a big demand for programmers who have programmed Java and C++ on Unix as opposed to Windows. My question is what are the differences a High Freq programmer would come across? It cannot be something in the language itself because syntactically they do not differ over OS? Therefore I thought it must be something which the programming language has to interface, resources etc? Could anyone please help me out as I am trying to improve my C++/Java on Unix, in order to aim for this type of career? ps I'm guessing part of this answer lies with the socket infrastructure on Unix?

• Starting multiple Chrome full screen instances on multiple monitors from (batch) script

  - by Bob Groeneveld

  My goal is to show different web content full screen on multiple monitors automatically after booting from a single computer. The browser I would like to use is Chrome. If Chrome does not support this and Firefox does that would be fine. The OS I would prefer is Windows, if it turns out that Linux is possible that would be fine. On Windows it is possible to set the position of the Chrome browser window (--window-position=) and make Chrome start in full screen mode (--kiosk). Using these options combined you can start Chrome full screen on any of the desktops/screens that you have connected to your computer. I have managed to get this working. However, if I then try to do the same thing a second time to have Chrome full screen on a second screen the second Chrome window will open over the first window, no matter the coordinates I use for the --window-position parameter. I have tried using Chrome profiles and copying the Chrome directory and starting the second chrome.exe. All these things result in the same behaviour.

• Switching to HTTPS - redirect question

  - by seengee

  Following the recent Google announcements about improved ranking for sites running on https we have a number of clients asking about this. Is it safe to just 301 redirect all pages to their SSL equivalent, for example in a common PHP include file: if($_SERVER['HTTPS']!="on"){ $redirect= "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; header("Location:$redirect",true,301); exit(); } Obviously I'm aware this is also possible within a .htaccess file but that cannot be modified in our case. Obviously all internal links would be switched to https:// links but obviously we need to sort out incoming links from Google and elsewhere. Is this a sound approach? Are there any other gotchas to be aware of?

• BDD in a .NET environment

  - by Nick

  I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily. I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'. Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD. I have two questions really: Is BDD adopted by companies out there? Who are they? How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?

• Whats the easiest route to trying out mono 2.6?

  - by E J

  We have several web applications built on Microsoft technologies (asp.net+mvc framework, built using VS2008, MS SQL Server). I have recently be playing with Ubuntu (9.10), installed using Wubi, and wanted to see if I can get our apps running on a foss software stack. I have got the hang of the very basics of Postgresql and I have read that there is some support for Linq to SQL in mono (as of 2.6) as well as asp.net/MVC. However I am unsure how to go about getting Mono 2.6 up and running. Here is what I have discovered so far: Ubuntu is not meant for the 'cutting edge' it is designed to be stable hence, it sometimes takes a release cycle or two for new software to make it to the repositories Mono is already installed by default, but it is likely to stay at version 2.4 for at least the 10.4 release You can install paralell environments of Mono, if you know what your doing. I have had a go at setting up parallel environments, but haven't had any luck yet. (And TBH I am not certain that that will do what I think it's gonna do). (tl;dr start here) Is there a distribution of Linux similar enough to Ubuntu, that I wouldn't have to start the learning curve all over again, but that will let me install Mono 2.6, Postgresql, (and possibly mono-develop 2.4)? Or should I persist with Ubuntu?
