• Is there a sensible way of 'teaming' two ADSL connections?

  - by Tim Long

  I work in an office complex that has two seperate ADSL connections, which they use to provide two seperate networks (actually both the ADSL routers go into a Cisco managed switch with two VLANs, one for each ADSL connection). Circumstances have changed so that 95% of the users are all on one ADSL connection. It would be great if there were a way to join together both connections to emulate a single connection at double the speed, but the ISP doesn't support bonding. So, is there a sensible way to take two completely seperate ADSL lines and use them to provide a single internet gateway?

• If a library doesn't provide all my needs, how should I proceed?

  - by 9a3eedi

  I'm developing an application involving math and physics models, and I'd like to use a Math library for things like Matrices. I'm using C#, and so I was looking for some libraries and found Math.NET. I'm under the impression, from past experience, that for math, using a robust and industry-approved third party library is much better than writing your own code. It seems good for many purposes, but it does not provide support for Quaternions, which I need to use as a type. Also, I need some functions in Vector and Matrix that also aren't provided, such as rotation matrices and vector rotation functions, and calculating cross products. At the same time, it provides a lot of functions/classes that I simply do not need, which might mean a lot of unnecessary bloat and complexity. At this rate, should I even bother using the library? Should I write my own math library? Or is it a better idea to stick to the third party library and somehow wrap around it? Perhaps I should make a subclass of the Matrix and Vector type of the library? But isn't that considered bad style? I've also tried looking for other libraries but unfortunately I couldn't find anything suitable.

• Lexmark E240 printing issues

  - by NoamH

  I have Lexmark E240 laser printer. I have been using it with 12.04 (32bit) for 2 years with no significant issues. Since lexmark does not support this printer on linux, I used alternatives drivers that were suggested by the community, such as HP-lasterjet, E238, generic PS, etc. They all worked fine, more or less. After upgrading to 14.04 (64bit fresh install) I tried to configure the printer as before, but now I have problems. The test page is ok, but when printing, most of the times, the first page in the document will be printed very partially and in 300% zoom. Next page might be ok. If I turn off the printer and back on, the first page might be ok, but in the next print job, it will be broken again. I used all the above printer options. Same results. I did NOT install the lexmark drivers since they are intended for 12.04 and the package manager report that it is in "bad quality" (don't know why). Does anyone has any experience with this printer in 14.04 64bit ?

• Is there anything like a link or shared mount point for FAT32 folders in Linux/Android?

  - by endolith

  I often want the same files to be accessed by different apps on my Android phone, but the apps look in different folders. Is there a way to make two different folder paths on a FAT SD card point to the same file? For EXT, I think I could do this with a symbolic or hard link, but those don't exist for FAT. Can FAT be extended to support them? Can Android use an EXT-formatted SD card? Can a folder be mounted on top of another folder? If this does exist, does it have any negative side effects?

• ISCSI: Ethernet cable maximum length vs. SCSI command timeout

  - by Jeremy Hajek

  I have a question about a non-optimal setup and the practical implications of this. Ideally you would place the ESXi server right in the same room as the FreeNas white box end of question. My situation is this: I have a run of ~125ft of Cat 5e connecting a ESXi server to a FreeNas whitebox in the server room. I know the distance of the ethernet cable is within the maximum distance for ethernet traffic but I have two questions... Can Cat 5e support gigbit speeds at that distance if the switch on the back end is a linksys SRW-2048? Should I be concerned about the distance causing data read and write timeouts in the SCSI portion--(disk operations of the ESXi)?

• Why do programmers write closed source applications and then make them free? [closed]

  - by Ken

  As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubicle. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

• Suggestions to start a cross-platform project

  - by Gabriele

  I have a big project in my head, it should be cross-platform (Win, Max and Linux), online (Client - Server) and with 3D graphics. I would like some suggestions to start with the right things. Currently I'm a PHP/MySQL coder, I used to code in C and Pascal on DOS ages (Borland Times ;)), my C knowlegde need a refresh but it's ok. I guess C++ it's the right language. What platform and what i should use to code? I can choose from all three platforms. My idea was to use Visual Studio 2010 C++, but i'm not sure if it support Native code. What kind of libraries should i use? I guessed OpenSSL for the login, OpenGL for graphics part. For the Audio or the GUI? Any other suggestions are well accepted. I know it's a "BIG DEAL" but I have no rush and it'll be a free-time project, only for my pleasure. Thank you in advance.

• The application attempted to perform an operation not allowed by the security policy

  - by user16521

  I ran this command on the server that has the share of code that my local IIS site set to (Via UNC to that share): http://support.microsoft.com/kb/320268 Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe -m -ag 1 -url "file:////\\computername\sharename\*" FullTrust -exclusive on (obviously I replaced Drive with C, and the actual computername and sharename with the one I'm sharing out). But when I run the ASP.NET site, I am still getting this runtime exception: Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

• Wordpress blog penalized by Google search - what's wrong?

  - by pawelbrodzinski

  I have a blog (http://blog.brodzinski.com), which is wordpress.org blog with pretty popular Thesis theme with almost no other customizations. Some time ago it was penalized by Google search - it simply stopped appearing in search results even for search terms it used to be top result, like my name - Pawel Brodzinski - which isn't anything close to popular search term. To be exact the site has been penalized on Nov 18. It started popping up in search result on Dec 23 but only for a few days. Since Dec 27 it is out again. I know Google guidelines and I'm not aware to break any of them. I submitted reconsideration request after I noticed penalty. It was proceeded and there was no change whatsoever (no surprise as it seems the site was penalized again). I checked diagnostics in webmaster tools and neither any malware was detected nor any strange search terms popped up. I read related threads on Google webmasters forum but found none of solutions working for me. I posted a thread on Google webmasters forum (http://www.google.com/support/forum/p/Webmasters/thread?tid=546339f49d4a03bc&hl=en) and the only answer I got was to check for duplicate content. Well, there is some duplicate content published on the web but it is true for vast majority of blogs and it doesn't seem to be a reason for a penalty. Also before Dec 27 I was able to remove duplicate content from a couple of sites which were republishing my feed but this doesn't change the situation - the site was penalized again. The problem is I have no idea what can be wrong with the website or how to find it out. To make the problem worse I'm no webmaster, I just run a wordpress blog, which supposed to be easy.

• Why doesn't Windows 7 allow me to format?

  - by hydroparadise

  Dell support can be fun to deal with right? Ultimately, I have been going back and forth with Dell on an issue and came to reinstalling Windows 7 32-Bit Pro. The problem is that Windows Setup will not let me format. I've read other posts that say Windows 7 must installed on first partition here. But now that confuses me because the computer came shipped with the installation on the third partion as shown in the picture below? Is there a real problem? Or is this a Microsoftism? Should I obliterate the "OEM" partition to make this work? Please note that the format, delete, new, and extend options are grayed out.

• How do UEFI and virtual machines relate to each other?

  - by Iterator

  I am trying to get my head around UEFI (Unified Extensible Firmware Interface) and it's not entirely clear to me how this affects virtual machines. Thus, there are three parts to this question: Is UEFI an advance in hardware support for virtualization? All other things being equal, would a machine with UEFI be more likely to run a virtual machine more efficiently than one without, or does UEFI cause any performance hits that negate any speed improvements from a virtual machine? Would the difference in execution be visible to code running in a virtual machine? (In theory, it shouldn't, but in practice?)

• MAMP PHP5.3 and 5.4

  - by musoNic80

  I've just downloaded the latest version of MAMP (2.1) but have run into a few issues. I'm developing using Symfony2 which requires php5.3 minimum. It also requires a php accelerator, ideally APC. So, I set MAMP (I'm not using MAMP PRO) to use php 5.4. Problem solved, I thought. Apparently not though. It turns out MAMP have decided not to support APC (or any accelerator as far as I can see) with their 5.4 version apparently due to it being buggy (really?!?!). Ok, so I'll just use 5.3 instead. Apparently not. It turns out that although MAMP has installed 5.3 on my machine I can't select it in the preference pane. I get a choice of 5.2 or 5.4! Is there a workaround for this?

• Adding SPF records in GoDaddy

  - by Mayank swami

  I have the GoDaddy hosting and send mail using the following code: $to = "[email protected]"; $subject = "Test mail"; $message = "Hello! This is a simple email message."; $from = "[email protected]"; $headers = "From:" . $from; mail($to,$subject,$message,$headers); echo "Mail Sent."; When the mail arrives at its destination I see the following (in red outline) I don't want to show the "via server" and for that there is an option to add a SPF record. To do this I have followed the instructions in this page: Managing DNS for Your Domain Names but it's not working. After that i have tried: v=spf1 include:_spf.google.com ~all as described in http://support.google.com/a/bin/answer.py?hl=en&answer=178723 but I still get the same result. How can I solve this and prevent "via server" showing?

• Advice on developing a social network [on hold]

  - by Siraj Mansour

  I am doing research on assembling a team, using the right tools, and the cost to develop a highly responsive social network that is capable of dealing with a lot of users. Similar to the Facebook concept but using the basics package for now. Profile, friends, posts, updates, media upload/download, streaming, chat and Inbox messaging are all in the package. We certainly do not expect it to be as popular as Facebook or handle the same number of users and requests, but in its own game it has to be a monster, and expandable for later on. Neglecting the hosting, and servers part, i am looking for technical advise and opinions, on what kind of team i need ? how many developers ? their expertise ? What are the right tools ? languages ? frameworks ? environments ? Any random ideas about the infrastructure ? Quick thoughts on the development process ? Please use references, if you have any to support your ideas. Development cost mere estimation ? NEGLECTING THE COST OF SERVERS I know my question is too broad but my knowledge is very limited and i need detailed help, for any help you can offer i thank you in advance.

• EMC CX3-10c Fault Condition won;t clear

  - by ITGuy24

  We have an old CX3-10c from Dell that had both Standby Power Supplies (SPS) fail. This obviously caused a fault on the system and disabled the cache. We have replaced the SPS's and they test fine as do all other components. Problem is there is still a fault on the "Enclosure SPE [SPE3]" despite all the component in the enclosure showing as good. I was on the line with Dell Gold support for 3 hours yesterday, they have had me restart the SPs multiple times, as well as reseat the power supplies, even shutdown the system completely and power it back on. All to no avail. Fault remains and cache cannot be re-enabled so long as the Fault is present. Any suggestions on clearing this erroneous fault?

• how to create a mirror of minimum size to install Ubuntu

  - by Registered User

  I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like http://bderzhavets.wordpress.com/2008/10/28/install-ubuntu-intrepid-server-pv-domu-at-xen-33-port-via-httpgetco-centos-52-dom0/ the host and client are both going to be my laptop, I Google d and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree.Which is where I have to do this work.So I have to create a URL structure which is similar to Ubuntu mirrors.So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

• Plug and Go NAS Storage

  - by graham.reeds

  My wife and I are separating. One of the things we need to extricate is the media we have accumulated over the years. So I am looking for a NAS solution that is a) relatively low-cost, b) reliable and c) easy for a non-geek to use (I don't want to be tech support). All it needs to do is hold our iTunes library, photos, course work and maybe some movies and TV shows that I currently have. She will be connecting via her Netbook. I have seen this thread but the reviews on Amazon aren't particularly favourable. Due to the need for simplicity, WHS and FreeNAS are none-starters. I need redundancy as if a single drive system was to die then she would lose her course work and photos. Is the ReadyNAS the only real solution out there?

• What is the basic loadout for an open source web developer?

  - by DeveloperDon

  Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

• Getting Started with GlassFish 4 and OEPE

  - by gstachni

  Oracle Enterprise Pack for Eclipse 12.1.1.2.2 introduces new support for GlassFish 4.0, the reference implementation of Java EE7.  Getting started with GlassFish 4.0 in Eclipse couldn't be easier. Follow these short steps to get GlassFish 4.0 setup so you can start developing, deploying, and debugging your Java EE7 applications. Prerequisites GlassFish 4.0 Oracle Enterprise Pack for Eclipse 12.1.1.2.2+ from OTN or Eclipse Marketplace Setting up the server connection In the Servers view, click to add a New > Server . Select GlassFish 4.0 from the list of supported server configurations. Pick your GlassFish installation directory (usually <glassfish 4>/glassfish) and select your domain. After you click Finish you should now be setup to launch Glassfish 4.0 in normal and debug mode within Eclipse as well as associate projects for deployment through the Add and Remove wizard. Using GlassFish tools in Eclipse GlassFish server tools provide some useful information about your running GlassFish 4.0 environment. Resources displays current resources deployed in the domain including your JDBC Connection Pool and JDBC Resource names. I find this extra bit of information useful when working with JPA. Deployed Applications shows the current active deployments in GlassFish which can be undeployed as needed from within Eclipse. Deployed Web Services provides information about SOAP-based web services deployed in this domain. Also with the running server are quick launch links to open the Administrative Console, Server Logs, and the GlassFish Community Site all within Eclipse's embedded browser.

• What is the philosophy/reasoning behind C#'s Pascal-casing method names?

  - by Nocturne

  I'm just starting to learn C#. Coming from a background in Java, C++ and Objective-C, I find C#'s Pascal-casing its method-names rather unique, and a tad difficult to get used to at first. What is the reasoning and philosophy behind this? I'm guessing it is because of C# properties. Unlike in Objective-C, where method names can be exactly the same as an instance variables, this is not the case with C#. I would guess one of the goals with properties (as it is with most of the languages that support it) is to make properties truly indistinguishable from variables and methods. So, one can have an "int x" in C#, and the corresponding property becomes X. To ensure that properties and methods are indistinguishable, all method names I'm guessing are also therefore expected to start with an uppercase letter. (This is just my hypothesis based on what I know of C# so far—I'm still learning). I'm very curious to know how this curious guideline came into being (given that it's not something one sees in most other languages where method names are expected to start with a lowercase letter) (EDIT: By Pascal-casing, I mean PascalCase (which is basically camelCase but starting with a capital letter). Method names typically start with a lowercase letter in most languages)

• Running NginX (with Apache) and cPanel/WHM

  - by ub3rst4r

  I was wondering if its a good idea to be running NginX as the webserver (on port 80) and Apache as the reverse proxy (on port 8080) with cPanel/WHM being used as a control panel? I also installed Nginx Admin so the configuration for NginX is managed by WHM. The reason I am asking is because I came across an article (http://kbeezie.com/view/apache-with-nginx/) which explains how to setup Apache as a reverse proxy but it states If you are using a control panel based hosting such as cpanel/whm, this method is not advised. Most of the servers configuration is handled automatically in those cases, and making manual changes will likely lead to problems (plus you won’t get support from the control panel makers or your hosting provider in most cases). Anyone have any past experiences with this and can say if its good/bad idea?
