• Ubuntu install and dual Boot with Windows 8 UEFI

  - by Jose Maria

  i have Ubuntu 12.04 x64 ISO, i load it on a Fat32 USB. My notebook has a hdd with GPT where i installed Official Win 8 Pro x64 (final versión), I partitioned the whole hdd, previously of win 8 install, and bios is set with UEFI boot. My BIOS notebook doesn't support SECURE UEFI BOOT. So I boot the notebook from USB and the Grub runs OK showing whether to run Ubuntu live or to install, but neither one neither two works, when I choose then the screen shows black and nothing happen, it doesn't start/loads the install program. I've try whether to prepare the usb with unetbootin, or just direct copy/paste the files onto the USB. I also have try WUBI, but neither with success, it launch an error when ending.

• Unity3d web player fails to load textures

  - by José Franco

  I'm having a problem with Unity3d Web Player. I have developed a project and succesfully deployed it in a web app. It works with absolutely no problem on my PC. This app is to be installed on two identical machines. I have installed them in both and it only works properly in one. The issue I have is on a computer it fails to properly load the models and textures, so the game runs but instead of the models I can only see black rectangles on a blue background. It has the same problem with all browsers and I get no errors either by the player or by JavaScript. The only difference between these computers is that one that has the problem is running on Windows 8.1 and the other one on Windows 8 only. Could this be the cause of the issue? It works fine on my computer with Windows 8.1. However both of the other computers have specs that are significantly lower than mine. I have already searched everywhere and it seems that it has to do with the individual games, however I think it may have to do with the computer itself because it runs properly in the other two. The specs on the computes I'm installing the app on are as follows: Intel Celeron 1.40 GHz, 2GB RAM, Intel HD Graphics If anybody could point me in the right direction I would be very grateful I forgot to mention, I'm running Unity Web player 4.3.5 and the version on the other two computers is 4.5.0

  - by JITHIN JOSE

  How much frequently google fetches sitemaps? I am now working with a high traffic website normally have 30 new posts per minute.But currently it provides sitemaps which links to new 100 posts(3 minutes). Is this method is enough ?. Is Bots fetch sitemaps every 3 minutes?. Did need to change sitemaps to list all 5M posts(indexed sitemaps)?. How this change will effect on traffic and page rank. Is google bot remove urls that previously listed on sitemap but not now?

• Why is JavaScript not used for classical application development (compiled software)?

  - by Jose Faeti

  During my years of web development with JavaScript, I come to the conclusion that it's an incredible powerful language, and you can do amazing things with it. It offers a rich set of features, like: Dynamic typing First-class functions Nested functions Closures Functions as methods Functions as Object constructors Prototype-based Objects-based (almost everything is an object) Regex Array and Object literals It seems to me that almost everything can be achieved with this kind of language, you can also emulate OO programming, since it provides great freedom and many different coding styles. With more software-oriented custom functionalities (I/O, FileSystem, Input devices, etc.) I think it will be great to develop applications with. Though, as far as I know, it's only used in web development or in existing softwares as a scripting language only. Only recently, maybe thanks to the V8 Engine, it's been used more for other kind of tasks (see node.js for example). Why until now it's only be relegated only to web development? What is keeping it away from software development?

• Strategy to store/average logs of pings

  - by José Tomás Tocino

  I'm developing a site to monitor web services. The most basic type of check is sending a ping, storing the response time in a CheckLog object. By default, PingCheck objects are triggered every minute, so in one hour you get 60 CheckLogs and in one day you get 1440 CheckLogs. That's a lot of them, I don't need to store such level of detail, so I've set a up collapsing mechanism that periodically takes the uncollapsed CheckLogs older than 24h and collapses (averages) them in intervals of 30 minutes. So, if you have 360 CheckLogs that have been saved from 0:00 to 6:00, after collapsing you retain just 12 of them. The problem.. well, is this: After averaging the response times, the graph changes drastically. What can I do to improve this? Guess one option could be narrowing the interval duration to 15 min. I've seen the graphs at the GitHub status page and they do not seem to suffer from this problem. I'd appreciate any kind of information you could give me about this area.

• CCMoveBy values on update()

  - by Jose M Pan

  Hope you can help me. This is my problem: I have a scheduled update, here I track the movements of my objects (sprites), I move them with CCMoveBy, and I need to constantly update the zOrder. For setting the zOrder I've made a setZOrder(), which it takes the actual position of the sprite. And here is the problem, I get all the X and Y values AFTER the object is in the target. I know I get the values after the object is in the new position because I've made a CCLog. I can read all the values from the sprite, only when it's in the new position, so everything is well sorted only when the objects are not moving. How can I get the CCMoveBy values on every tick update? (or how can I get the CCMoveBy values in "real-time"?) Thanks a lot in advance, Here is an idea of my code. this->schedule(schedule_selector(Game::update)); void Game::update(float dt) { setZOrder(); moveObjects(); } void Game::setZOrder() { //This function takes the X and Y position and the row and column where the sprite is. Is working good. But I'm getting the "move" action values, after the object is in place. } void Game::moveObjects() { for (i=0; i < numChildren; i++) { CCActionInterval* move = CCMoveBy::create(targetPoint, time); object[i]->runAction(move); } }

  Is there any good open source alternative to OpenBiblio that can be ran on hosting package I have from undisclosed hosting company that does not give out root access to the server. I have seen that Koha and Evergreen needs root access and does not meet compatibility standard on my hosting package. Is there any good open source ones that can be ran with PHP and MySQL and community maintained and updated?

• conditional selection of decimal-format in xslt

  - by Jose L Martinez-Avial

  Hi all, I'm trying to modify the decimal-format of a stylesheet based on certain information of an XML. More exaclty, I've a XML like this <?xml version="1.0" encoding="ISO-8859-1"?> <REPORT> <LANGUAGE>2</LANGUAGE> <MYVALUE>123456.78</MYVALUE> </REPORT> I'm trying to define the decimal format as european if the language is 2, and default otherwse. So I've created the following template <xsl:template match="REPORT"> <xsl:if test="$language=2"> <xsl:decimal-format decimal-separator=',' grouping-separator='.' /> </xsl:if> <xsl:value-of select ="format-number(MYVALUE,'###.###,00')"/> </xsl:template> So it shows the number in european format or in standard format. But I'm getting the following error xsl:decimal-format is not allowed in this position in the stylesheet! If I try to put the decimal-format outside the template, then I get the message that the xsl:if is not allowed in this position in the sthylsheet. How can I change the decimal-format based in the XML? Thanks Jose

• Bypassing Router's DNS Settings

  - by Ramon Marco Navarro

  Is there a way to bypass my ISP provided CPE/router's DNS settings? I'd like to use OpenDNS but I am unable to access the administrator acount of the CPE. I tried logging in using the default passwords (admin/admin, admin/1234, etc) to no avail. I found out later that the admin password is generated using a generator where you input the CPE's MAC address. I tried emailing the manufacturer of the CPE (Huawei, the CPE is Huawei BM625) and my ISP but they aren't replying. I also saw similar queries (lots of them!) at Huawei's forums, without a single reply. So as a last resort, I'd like to know a way to bypass the CPE's DNS settings. My subscription is for a WiMAX service. I'm using Windows 7 and have already set the DNS settings for the Local Area Connection. But I still am not seeing the "You are already using OpenDNS" text at OpenDNS's site. And when explicitly using the OpenDNS servers I still seem to get 208.69.38.150 rather than the expected 208.69.38.160: nslookup www.opendns.com. 208.67.222.222 Server: resolver1.opendns.com Address: 208.67.222.222 Non-authoritative answer: Name: www.opendns.com Address: 208.69.38.150

• Windows Clients: Windows or Linux Domain Controller?

  - by Ramon Marco Navarro

  I'm planning to set up a domain controller for our small computer laboratory. I'm a little confused as to what operating system to use for our domain controller. What's in the lab: The lab has 25 units running a mix of Windows 7 and Windows XP. The domain controller will only have 2GB of RAM running a C2D E7200. (Is this enough?) What we want: The Domain Controller will also be running a git server. The Domain Controller will also be used as a general development machine (mostly Java, PHP). A way to centralize the updates for the windows clients, so that they won't have to download the same patches from the remote site. The machines would just query them from the local domain controller and get the updates from there. Our head recommended that I virtualize a Windows Server 2008 system under a Linux host and use the former as a domain controller and the latter for development or the other way around. A comparison of the advantages and disadvantages of using a Linux distribution or Windows Server 2008 in this situation would also be appreciated. As you may have noticed by now, I'm kinda new to setting up a domain so I hope you guys will be able to help me. Thank you.

• Convert to WAN port

  - by Ramon Marco Navarro

  I have a ADSL2+ Modem/Router. Is it possible to set one out of four of the LAN ports as a WAN port? If yes, how? The brand/model is: Prolink H9200P. I already contacted Prolink about this and the site said to wait for one business day. But I'm still asking here just in case someone could answer faster than Prolink. Thank you.

• How to restore a VirtualBox image given the .vdi file

  - by Ramon Tayag

  Background I have VirtualBox on Linux and recently the drive with the system files failed on me. I'm able to use the Live CD to view the files of the storage drive, and through this, I can copy my data files to another computer while I work on this one. How do I load the .vdi in another computer (or in this case, the fresh install of Ubuntu)? I see many samples online of how to export it, but it assumes the host is currently working. Thanks!

• Windows 2003 Cluster: Failover Delay

  - by Ramon Marco Navarro

  I am testing the failover policies of our test failover cluster system. When I shutdown the node who is currently controlling the cluster (NODE1), it takes about 2 mins and 40 seconds before the next node on the preferred list (NODE2) takes control of the cluster. I tried changing the looksAlive and isAlive interval to 5000ms to all resources, but that didn't help. Looking at the Event Viewer of the remaining nodes, it shows that it was almost instantly detected that NODE1 was down. But it took another ~2:40 minutes for it to be removed from the live cluster list and for NODE2 to take over. Is there anyway of changing or shortening this "failover delay"? This is the setup of the cluster: (1) One ClusterDC connected to the public network (3) Three nodes running Win2003 with a quorum type of MNS Private network is connected to network hub ________________ _________________ (ClusterDC)=------=| |=------=(Node1)=------=| | |Public Network|=------=(Node2)=------=|Private Network| | (Switch) |=------=(Node3)=------=| (Hub) | ---------------- -----------------

• Monodevelop SVN 1.7 support

  - by Gustavo Rubio

  I'm trying to checkout an SVN repo and it does get checked out, however the solution is not opened by default. I then tried to simply open an already checked out folder and I do not get versioning support. I tried this in both Windows and Linux with no success with MonoDevelop 3.0.4 and 3.0.5 My guess is that since the .sln file is in the path /trunk/code/project/project.sln and the new 1.7 format keeps only one ".svn" folder at the top of the checked out folder (e.g. /home/gustavo/ProjectSrc/ ) hence MD not "finding" the versioned code. Anybody has had success using SVN 1.7 and MonoDevelop?

• Confused about SPF Record setup

  - by Ramon A.

  Hello, I'm confused on how I should set up SPF records for my multiple domains. Here is my configuration: the setup is: (a) domain1.com points to server1 (b) mail.domain1.com points to server2 (c) domain2.com is a vhost in server1 (d) domain3.com is a vhost in server1 (e) and so on.. I want the SPF record to be set up so that domain1.com, domain2.com, domain3.com are authorized to send emails using mail.domain1.com. I'm confused on wether to put the SPF record on each domain, or on the main server only.

• send arrow keys using ganymed ssh java

  - by José Ramón Pérez Rubio

  I am using Ganymed ssh to connect to a remote machine and apart from sending commands I need to send the arrows keys (left and right keys). I can send commands but when I send the arrows keys nothing happends. This is what I have: public boolean createShell() throws Exception { try { // ... m_session= connection.openSession(); m_commandWriter = new OutputStreamWriter(m_session.getStdin()); String encoding=m_commandWriter.getEncoding(); //encoding is UFT8 m_errorPipe=new SSHSyncPipe(m_session.getStderr()); m_outputPipe=new SSHSyncPipe(m_session.getStdout()); m_outputPipe.start(); m_errorPipe.start(); // m_session.requestPTY("bash"); m_session.requestDumbPTY(); m_session.startShell(); m_shellCreated=true; return true; } } So if I use m_commandWriter.write(ls"\r\n"); m_commandWriter.flush(); It works, but m_commandWriter.write(37);//37 is the code for left arrow m_commandWriter.flush(); Doesn't work. Does anyone know what I am doing wrong? Thank you

• How to automatically define functions and aliases on remote server after ssh login

  - by Ramon

  I want to define bash functions and aliases in my remote shell automatically on login. I can't put the definitions into .profile or similar because the users I log in as are often shared with others who use the same systems and I don't have control of this. What I'm trying to do is execute a few bash function definitions in the remote process and then continue as a login shell. I tried this but it did not work: cat ~/.profile - | ssh -tt user@host bash -l Any ideas?

• How do I pass a reference type to Control.Invoke / display a form centered on the main form

  - by Rubio

  I'm on a thread other than the UI thread and need to display a modal form that's centered on the application's main form. What I usually do is use the width and height of the main form and the modal form to calculate the location, then use the PointToScreen method of the main form to get the location of the modal form. Since I'm on another thread I need to use Control.Invoke to call this method. I just can't figure out how to pass a parameter of type Point to Control.Invoke (params object[]). Value types and String works fine. Or, if someone can find a better way to display a form centered on the main form regardless of thread, that would be great. MessageBox seems to be able to do this (although not modally).

• SSH equivalent of .profile/.bashrc

  - by Ramon

  I am looking for a way to automatically define some aliases inside my session on any server I ssh to. I can't put them in the .bashrc files on the server because the user accounts I log in with are shared by other people and besides there are dozens of them and maintaining a script on every machine would be painful. I know I could use expect to type the aliases automatically but I was just wondering if OpenSSH has anything built-in that could conceivably be used to achieve this?

• WinHttpCertCfg not importing certificate

  - by Ramon Zarazua

  I need to setup a deployment script that imports an SSL certificate that my service uses. I have tried importing with WinHttpCertCfg and with CertMgr to no avail. Here are the command-line arguments I have tried to use with both: winhttpcertcfg.exe -i <certname>.pfx -c LOCAL_MACHINE\My -p <password> -a <user service runs as> and CertMgr.exe -add -all -s -r localMachine -c <cert name> My It seems from what I have investigated that CertMgr does not allow you to import certificates with a password, so I'd rather get winhttpcertcfg working. When I run them I get the following output: WinHttpCertCfg: Microsoft (R) WinHTTP Certificate Configuration Tool Copyright (C) Microsoft Corporation 2001. CertMgr: CertMgr Succeeded However, when I look into the local machine certificates in MMC, try to load them from my service, or list it out through winhttpcertcfg, or even looking at the registry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates it is not found. I have tried all of the following: If I install the cert manually (Through CertMgr.msc dialogs) it works. The user installing is running as administrator The user installing has full access on the certificate The tools print out an error when something is wrong (wrong password) Tried it in multiple machines (All of them server 2008 R2) At this point I am officially out of ideas. Thank you.

• Reading same file from multiple threads in C#

  - by Gustavo Rubio

  Hi. I was googling for some advise about this and I found some links. The most obvious was this one but in the end what im wondering is how well my code is implemented. I have basically two classes. One is the Converter and the other is ConverterThread I create an instance of this Converter class that has a property ThreadNumber that tells me how many threads should be run at the same time (this is read from user) since this application will be used on multi-cpu systems (physically, like 8 cpu) so it is suppossed that this will speed up the import The Converter instance reads a file that can range from 100mb to 800mb and each line of this file is a tab-delimitted value record that is imported to another destination like a database. The ConverterThread class simply runs inside the thread (new Thread(ConverterThread.StartThread)) and has event notification so when its work is done it can notify the Converter class and then I can sum up the progress for all these threads and notify the user (in the GUI for example) about how many of these records have been imported and how many bytes have been read. It seems, however that I'm having some trouble because I get random errors about the file not being able to be read or that the sum of the progress (percentage) went above 100% which is not possible and I think that happens because threads are not being well managed and probably the information returned by the event is malformed (since it "travels" from one thread to another) Do you have any advise on better practices of implementation of threads so I can accomplish this? Thanks in advance.
