• Wordpress : Automatically transfer media files to Amazon S3

  - by Ron Ranieri

  I've been using VPS to host 7 Wordpress websites, most of them require big storage but very little RAM and traffic. So I'm thinking of moving the static files(uploads folder) content to Amazon S3 and I'm looking for the most viable solution to this. I want every website to have their own bucket and newly uploaded media files automatically uploaded to Amazon S3 without using plugin. I'm ok with cron job, for example the files were uploaded first to my server, then transferred to S3 and deleted from my server every 24 hour. Or is there any way for me to change the default upload directory to my S3 bucket without sacrificing any Wordpress functionality(resize/title etc)? What do you think the most efficient way to do this? Currently I'm looking at this plus cron job but I would like to know better option if it exist.

• What companies do what I'm interested in?

  - by Alex

  I'm a systems guy. People change their concentrations to avoid taking operating systems, while I took it during my first semester after transferring. I'm taking compilers and networks now, and I think they're awesome. And yet there are so many job postings looking for people to do work in things like web development, and so few postings looking for people to work in kernel hacking or network engineering. What sorts of companies do these things? I'm currently awaiting a contract in the mail for an internship with VMWare, so I'm not out of a job for the summer. Still, I'd like to companies do these things.

• Disabling IPv6 on a single interface

  - by ijw

  I'm slightly weirded out by the fact that Ubuntu won't process ipv4 DHCP unless you explicitly tell it to, but will happily take ipv6 RAs unless you tell it not to. Is there any way to change the default behaviour to be 'do nothing unless I explicitly turn it on'? (Note to answerers: I'm not looking to globally disable ipv6, or completely turn off autoconf. I'm looking to disable autoconf by default (as in, I don't want ipv6 unless I say so in /etc/network/interfaces, in the same way that I don't just get a v4 address unless I've explicitly turned on dhcp). What's happening is that, for any interface that's up - e.g. has an ipv4 config - a v6 address tends to just turn up on the interface as well, despite the fact that I've not enabled that explicitly. The solutions to date are fine as far as they go, but if I disable v6 or autoconf globally, I can't then re-enable v6 on a per-interface basis with a simple command in /etc/network/interfaces. I'm fairly sure I'm asking for the moon on a stick, mind you.)

• Help file formats - MSHA files v CHM files

  - by TATWORTH

  Recently I was tasked with producing a help file from a C#/WPF/Crystal Reports application using Sandcastle. I have previously blogged about the problems in doing that and the change that is going into the next version of Sandcastle that allows the vagaries of Crystal (this missing BusinessObjects.Licensing.KeycodeDecoder) to be handled. At http://social.msdn.microsoft.com/Forums/en-US/devdocs/thread/0b110502-f5bb-4c56-96a5-4347a2a7a68a/, I describe how I tried each of the formats. Two of the formats could not be built and the error messages were not exactly helpful as to the cause. These two formats turned out to be obsolete. The MSHA format worked but was not suitable for a standalone application, so that left me with the older CHM format. I therefore asked on that thread "will the HTML Help 1 (CHM) format continue to be supported for the foreseeable future?".Rob Chandler, MVP in help systems, gave a very helpful answer, to the effect that there is not yet a replacement for the CHM format.

• how to remap Ctrl to Escape if pressed and released on its own

  - by psvm

  I want to remap Control, so that: A. If it is pressed and released with no other key, it acts as Escape. B. If it is pressed & held together with another key, it acts as Control (no change in behavior in this case). I'm aware of How do I remap certain keys?, so I suspect it may be done with xmodmap. But that answer does not explain how to map the modifier keys. I looked into the examples and grammar sections of the xmodmap manpage, but they do not explain that. The answer in Remapping Caps Lock to Control and Escape (not the usual way) mention that it is not possible to do that to CapsLock, since it is a Lock key, but I hope this may be possible to do it with Control which is a mod key. A solution with something different than xmodmap will also be accepted. (I'm running Xmonad in Ubuntu 12.04, so perhaps there is a way to set this up in xmonad.hs?)

• How to disable Gnome-Shell auto-open in Dashboard

  - by user48027

  I am personalising my Gnome-Shell in Ubuntu 11.10 I would like to disable the feature to open the Gnome's Dashboard when I close the last Window in a Workspace. Edit to clarify: The dashboard is available only in GNOME Shell. The dashboard opens if you press the windows key (aka SUPER) or if you move the mouse to the upper left corner. If you close the last window of a workspace, but there are open windows on other workspaces, the dashboard opens automatically. The latter behaviour is annoying if you do not want to use the dashboard to open new windows or to change workspace. There are many ways to to both (Gnome do, Docky, keyboard shortcuts, clicking on something on the desktop, ...). Edit: There is a related Q&A, which was closed because the asked the same question for Mint: How can I prevent the activity view for opening when I close the last running app?

• Design for future changes or solve the problem at hand

  - by Naveen

  While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because, trying to generalize the problem tends to complicate the things (which may not be necessary) and on the otherhand it will be very difficult to extend the specific solution if there is a change in the requirement. I guess the solution is to find the middle path which is easier said than done. How do you tackle this type of problem ? If you start generalizing it at what point of time you know that this much of generalization is sufficient ?

• Do search engines rank internal redirects negatively?

  - by siverd

  A client is in the late stages (code complete) of a website redesign and unfortunately hasn't implemented 301 redirects to point high traffic pages to the new URL's. As I understand it our only option at this point is to create redirects within the CMS. Our CMS allows us to do this: www.mysite.com/category/current-page.html will redirect to www.mysite.com/new-category-name/new-page.html The site now uses custom logic on our 404 page to check this list of redirects and if one exists forwards the user to the new-page.html I understand that using 301 redirects would be the correct way to maintain our page rank but I think that would require a code change which isn't possible. Question How will search engines respond to this? Will they wait until the redirect happens and allow us to keep our page rank (authority, trust, etc) or will they see the 404 page and down-rank us? Worst case...will they make our new-page.html start from a rank of "0"? Thanks for your help.

• How can I have a Bluetooth Keyboard Auto-Connect at Startup?

  - by Grant

  I have a bluetooth keyboard for my HTPC. I pair it with my computer via bluetooth, and it works fine. However, when I turn off the keyboard or my computer, it has to connect again (which requires me entering a passcode on the computer and keyboard) when I turn them back on. I've looked through many forums and through that I have found that I'm missing some seemingly vital bluetooth files: /etc/default/bluetooth /etc/init.d/bluetooth /etc/bluetooth/hcid.conf In the instructions that I've found online so far, I must change certain lines in any of these files. I am unable to, since they do not exist. Am I missing a dependency or something? I've also tried installing Blueman but that didn't help at all. I'm running Ubuntu 10.10 (Maverick). Original post: http://ubuntuforums.org/showthread.php?t=1643386&highlight=bluetooth

• Is excessive indirection and/or redundant encapsulation a recognized concept?

  - by Omega

  I'm curious if there's a series of tendencies or anti-patterns when programming whereby a developer will always locally re-wrap external dependencies when consuming them. A slightly less vague example might be say when consuming an implementation of an interface or abstract, and mapping every touch-point locally before interacting with them. Like an overcomplicated take on composition. Given my example, would the interface not be reliable enough and any change to it never be surmountable any any level of indirection? Is this a good or a bad practice? Can it ever go too far? Does it have a proper name?

• How to add reflection definition to read JSON files in web game

  - by user3728735

  I have a game which I deployed for desktop and Android. I can read JSON data and create my levels, but when it comes to reading JSON files from web app, I get an error that logs, "cannot read the json file". I researched a lot and I found out that I should add my JSON config class to configurations, so I added this line to gameName.gwt.xml, which is in core folder: <extend-configuration-property name="gdx.reflect.include" value="com.las.get.level.LevelConfig"/> But it did not work out. I have no idea where should I place this line or where I should change to make my web app work, so I can read JSON files.

• Floppy Drive not recognised

  - by Art

  I am a newbie with Ubuntu during the past two weeks, and I believe, that I have made good progress so far. Current setup tasks are completed, like: "Wireless Network, Printer, Thunderbird + Firefox, e-mail", also my local weather station - all setup. Updated files and rearranged the desktop to my liking. The problem I have now is my floppy drive which is not recognized, but the activity light is shown on constantly. I have downloaded the "MakeFloppyDriveAvailableToEveryone" and i am confident that I can follow the instructions to change the floppy drive. However, I do not have an existing fd0 file in /dev/???, but only /dev/fd/ files 0 to 46. Please advise.

• MacBookPro 7,1 can only see one cpu

  - by gozzilli

  On a MacBookPro 7,1 running ubuntu 11.10, System monitor only sees 1 core (instead of 2). cat /proc/cpuinfo | grep 'cpu cores' also gives: cpu cores : 1 I followed this guide and added acpi_apic_instance=2 to the line with GRUB_CMDLINE_LINUX_DEFAULT, but that doesn't seem to change the situation. What can I do? I'm using rEFIt, installed under MacOS, and running in dual boot with MacOS. After the rEFIT menu, I'm still presented with the GRUB menu (I'm assuming that's normal). I saw similar posts on this matter, but could not fix my problem with what they suggested. EDIT: With the method mentioned above the computer runs sometimes with 1 core and other times with 2. Why is that? How can it be fixed?

• Responsive Menu Navigation [closed]

  - by Aaron Brewer

  I am sure you all have heard of Responsive/Adaptive Website Design and Development, but for the sake of beginners to the technique and skill, what are ways to create a Responsive Menu Navigation? I know there are a few standard ways, hence: JavaScript/jQuery Menu that changes functionality at different breakpoints. CSS3 Menu that changes functionality at different breakpoints. If you have had the opportunity to create a Responsive Menu, what technique did you use? How did you do it? Do you have an example? Did your Menu change functionality at different break points?

• Session and Cache are By Reference

  - by nishan

• What is the concept behind writing a cancel operation in c++?

  - by ToMan

  I'm attempting to write a cancel operation for a software download application. This application will first transfer the software to the device and then install the software on it. (These are givens I'm not allowed to change). What should the cancel operation do? When a user presses 'cancel', the application should stop transferring/installing the software immediately. Question: Since I've never written a "cancel" function, I'm wondering what are the types of things to consider when writing the code, and what are the common bugs I should expect and how to deal with them? Couldn't find anything in google so if you have some links that would be good reads I'd really appreciate it since I'm not looking for answers I'm just looking for guidelines/macro/concept help

• Long term planning and agile?

  - by Ignite

  My team has recently went through the process of laying out a nearly one year plan for our direction of work. We have separated the plan into three phases and each phase will include a couple of launches. I wonder, from an agile point of you, is what we do wrong? I think it's not a bad idea, because we haven't spent too much time on designing anything but the first few steps and it's possible for us to change direction. At the same time it's nice that we don't act with only the near term in sight.

• Non persistent keyboard shortcuts in Unity

  - by nblumoe

  I did change the keyboard shortcuts for window navigation in Unity to use hjkl (vim movement). I did reassign the shortcuts via GUI in System Settings Keyboard Shortcuts. Here are two examples of the assigned shortcuts: Move window one workspace to the left = Shift+Ctrl+Alt+H Switch to workspace left = Ctrl+Alt+H Occasionally, when restarting the maching, these shortcuts are being reset to theit default values: Move window one workspace to the left = Shift+Ctrl+Alt+Left Switch to workspace left = Ctrl+Alt+Left How can I make these changes permanent? Can someone help me, narrowing down the problem?

• We have a 200% increase of "organic" search traffic - how to figure out which keyword is causing this?

  - by Robert Grezan

  So our Google Analytics are showing us that 200% increase of "organic" search traffic. Analytics are saying that search keyword is "(not provided)". We are wondering how to find out which keyword is causing this? We are monitoring all important keywords for our website. None of keyword is in first 5, so our "organic" serach traffic is modest. However, today we received 200% increase of "organic" search traffic but none of keywords we can think of moved a bit. We also did not change anything related to SEO. And what is interesting Google Webmaster shows no changes - ~2500 impressions and ~200 clicks. How to find out which "keyword" might be causing this spike?

• Avoid penalties for duplicate (multilanguage) shared hosting

  - by Dave

  My concern is about SEO. Now let me explain the scenario. I am making a 3 languages website. The development is alright, but I was targeting local customers with one domain, and international (english version) with another. Eg: Local http://www.minhalojadesapatos.com.br (this is not the real website, just example!) Other http://www.myshoesstore.com.br Both domain point to exactly the same hosting and content, but when user comes through local domain, default language is set to portuguese, otherwise, default is english. Language handling on backend uses PHP Sessions and cookies, so with just a click users can change content language. How to avoid being SEO-penalised in this context? (yeah, I was hungry when focusing market for choosing two domains but the activity really needs that, it is a travel agency).

• Do I have to learn html and javascript to create web applications?

  - by vainolo

  I am an experienced Java programmer, and I want to create a complex web application requiring dynamic pages, drawings, etc (take SO as an example). Do I have to learn javascript/html in order to create such an application? It is not that I don't want to learn another language (I've done this before), but technology on the javascript environment seems to change so fast that when you finish learning one framework it is already obsolete. I have checked a number of java framework for web development (spring, play), but not deeply. So can these frameworks (or other possible java frameworks that I'm not aware of) be used without learning html/javascript? I also have some python experience. So if I can do the app in python it is also an option.

• is jargon related to a frameWork (concept)

  - by MaKo

  If this is not the right place to ask this question please inform where it would belong, to change it... I have a doubt for the correct word or concept in english language [not my native], about the relationship of language to framework for example i work with objective C, with the cocoa touch frame work || python with the django frame work My comparison is between natural languages and formal languages, So would be in a natural language english and the frame work a [computer, it]jargon? Does this make sense? Or what other concept would be the relationship between natural language - framework?
