• Google Fonts API JSON Data in WordPress Options-Framework-Theme

  - by Rob

  I'm developing a child-theme off of the new Twenty Twelve theme using Wordpress 3.4.2 and the development version of the Options Theme Framework by Devin Price. In Devin's tutorial, it shows of a way to implement 15 Google Web Fonts into the Theme Options page, but not all of them (roughly 560). I know I can create a "manual list", like in the tutorial that states each one with fallbacks, but this is time consuming and unproductive as Google may or may not add to, update, change or remove some of these fonts from their list. The list I've created above will ultimately store unavailable fonts the user thinks is there because of what they can see in the drop-down menu and it won't have any new ones - making the list and some selections obsolete. On the Google Developer API Web Fonts page, it talks briefly on retrieving a "dynamic list" using JSON/JavaScript. I was wondering how would I be able to pull the Google Web Fonts API into my Wordpress Theme Options page so I'm not creating my own list or have to constantly release an update to solve this issue. Could someone please walk me through what I would need to paste into my options.php, functions.php, /inc/options-framework.php file etc. or even in a new one to implement this? I've also had a look into some screencasts, plugins and tutorials on how it works, but none of them are specific enough for people just starting out. Please keep in mind I'm not the best coder... Thank you.

• Changing The Text Selection Shortcuts on a Mac

  - by Berk U.

  I've recently switched over from a PC to a Mac and I'm wondering if there is any way to edit the text selection/deletion shortcuts on a Mac. I write a lot of code and I've found these shortcuts to be very helpful. Here is a quick overview of the deletion shortcuts (http://lifehacker.com/5803041/the-mac-os-x-delete-key-it-goes-both-ways); the selection shortcuts on the mac are similar, except that you can use arrow keys instead of delete. I'd be happy to learn of any method, though I would much prefer it if someone can come up with a way to do it using KeyRemap4MacBook.

• Why can't the Adobe Flash player send key strokes it doesn't handle to the browse in which it is run

  - by jim.e.clark

  I'm a heavy web user that uses the address bar constantly while browsing the web. I often use Ctrl + T to open a new tab or Ctrl + D to move focus to the address bar so it is very annoying that these shortcut keys do not work when a Flash object has focus on the active browser tab. I would happily give up all keyboard handling in the Flash Player in exchange for having keystrokes sent to the browser. In fact, as someone who has worked in software development for over 15 years it is hard to believe that Flash doesn't pass common browser shortcut keys to the browser or have an option to do so. So my question is this: Am I missing some option, some Flash shortcut key or some Firefox add-on that will alleviate my suffering?

• How can i resolve all external addresses to internal address?

  - by Darian

  I am currently setting up a Linux server for a WIFI access-point. When ever someone who is connected to the hotspot/access-point? tries to reload a page they get forced onto the one page. Note: this wont have internet access! ie: user tries accessing www.google.com = it returns 192.168.1.200 or example.domain I've read that "dnsmasq" can be used to redirect any external addresses to an internal address. but haven't had any luck. Anyone have an example of a config for "dnsmasq"? I have also read that this can be done through a proxy?

• What are the advantages and disadvantages to using your real name online?

  - by Jon Purdy

  As a programmer, do you see any professional or other advantage in using your real name in online discourse, versus an invented handle? I've always gone by a single username and had my real name displayed whenever possible, for a few reasons: My interests online are almost exclusively professional and aboveboard. It constructs a search-friendly public log of all of my work, everywhere. If someone wants to contact me, there are many ways to do it. My portfolio of work is all tied to me personally. Possible cons to full disclosure include: If you feel like becoming involved in something untoward, it could be harder. The psychopath who inherits your project can more easily find out where you live. You might be spammed by people who are not worth the precious time that could be better spent writing more of the brilliant software you're famous for. Your portfolio of work is all tied to you personally. It seems, anyway, that a vast majority of StackOverflow users go by invented handles rather than real names. Notable exceptions include the best-known users, who are typically well established in the industry. But how could we ever become legendary rockstar programmers if we didn't get our names out there? Discuss.

• Why does iTunes make 2 copies of my music when adding to library?

  - by NoCatharsis

  I set iTunes to "Keep iTunes Media folder organized" and to "Copy files to iTunes Media folder when adding to library" because I prefer to keep my music consolidated, organized, and consistent. However, when I have MP3s that are external to iTunes, then try to add via File Add Folder to Libary, iTunes creates 2 copies of the file in the iTunes folder - one with the original song name and another with the original song name followed by the number 1. Here is what I thought would happen, and I hope is possible: 1) Click File Add Folder to Library 2) Select folder external to iTunes 3) Click OK 4) iTunes creates a clean new folder in the iTunes Music directory with exactly 1 of each file 5) Only 1 of each song is shown within iTunes Is this too much to ask? I am not an iTunes fan at all after 2 years dealing with the poor programming of this application. I hope someone can help me find the faith...

• Order of operations to render VBO to FBO texture and then rendering FBO texture full quad

  - by cyberdemon

  I've just started using OpenGL with C# via the OpenTK library. I've managed to successfully render my game world using VBOs. I now want to create a pixellated affect by rendering the frame to an offscreen FBO with a size half of my GameWindow size and then render that FBO to a full screen quad. I've been looking at the OpenTK example here: http://www.opentk.com/doc/graphics/frame-buffer-objects ...but the result is a black form. I'm not sure which parts of the example code belongs in the OnLoad event and OnRenderFrame. Can someone please tell me if the below code shows the correct order of operations? OnLoad { // VBO. // DataArrayBuffer GenBuffers/BindBuffer/BufferData // ElementArrayBuffer GenBuffers/BindBuffer/BufferData // ColourArrayBuffer GenBuffers/BindBuffer/BufferData // FBO. // ColourTexture GenTextures/BindTexture/TexParameterx4/TexImage2D // Create FBO. // Textures Ext.GenFramebuffers/Ext.BindFramebuffer/Ext.FramebufferTexture2D/Ext.FramebufferRenderbuffer } OnRenderFrame { // Use FBO buffer. Ext.BindFramebuffer(FBO) GL.Clear // Set viewport to FBO dimensions. GL.DrawBuffer((DrawBufferMode)FramebufferAttachment.ColorAttachment0Ext) // Bind VBO arrays. GL.BindBuffer(ColourArrayBuffer) GL.ColorPointer GL.EnableClientState(ColorArray) GL.BindBuffer(DataArrayBuffer) // If world changed GL.BufferData(DataArrayBuffer) GL.VertexPointer GL.EnableClientState(VertexArray) GL.BindBuffer(ElementArrayBuffer) // Render VBO. GL.DrawElements // Bind visible buffer. GL.Ext.BindFramebuffer(0) GL.DrawBuffer(Back) GL.Clear // Set camera to view texture. GL.BindTexture(ColourTexture) // Render FBO texture GL.Begin(Quads) // Draw texture on quad // TexCoord2/Vertex2 GL.End SwapBuffers }

• Computer Science Degrees and Real-World Experience

  - by Steven Elliott Jr

  Recently, at a family reunion-type event I was asked by a high school student how important it is to get a computer science degree in order to get a job as a programmer in lieu of actual programming experience. The kid has been working with Python and the Blender project as he's into making games and the like; it sounds like he has some decent programming chops. Now, as someone that has gone through a computer science degree my initial response to this question is to say, "You absolutely MUST get a computer science degree in order to get a job as a programmer!" However, as I thought about this I was unsure as to whether my initial reaction was due in part to my own suffering as a CS student or because I feel that this is actually the case. Now, for me, I can say that I rarely use anything that I learned in college, in terms of the extremely hard math, algorithms, etc, etc. but I did come away with a decent attitude and the willingness to work through tough problems. I just don't know what to tell this kid; I feel like I should tell him to do the CS degree but I have hired so many programmers that majored in things like English, Philosophy, and other liberal arts-type degrees, even some that never went to college. In fact my best developer, falls into this latter category. He got started writing software for his church or something and then it took off into a passion. So, while I know this is one of those juicy potential down vote questions, I am just curious as to what everyone else thinks about this topic. Would you tell a high school kid about this? Perhaps if he/she already knows a good deal of programming and loves it he doesn't need a CS degree and could expand his horizons with a liberal arts degree. I know one of the creators of the Django web framework was a American Literature major and he is obviously a pretty gifted developer. Anyway, thanks for the consideration.

• Installing and maintaining an email server

  - by Andrew

  I need to move hosting providers for four or five domains and for several reasons I'm considering a Linux VPS rather than staying with my current shared, managed hosting provider. The only thing that's stopping me is email. I have lots of experience running and maintaining Apache, but none with email servers. Based on some research, if I want to keep what I've using now, it looks like I'd be going with Postfix and Dovecot, and probably Exim and SpamAssassin. I have no problem performing regular maintenance and watching for security updates, but I don't want to bite off more than I can chew. For someone new to email services, how hard is it to set up an email server that is externally accessible (via SMTP and POP3, not IMAP), available over SSL/TLS and reasonably reliable for multiple domains? How much of a time commitment is it to maintain one?

• Can I repair a short circuiting problem in a Dell Inspiron 6000 that occurs when it is picked up?

  - by jim.e.clark

  I have a couple of Dell Inspiron 6000 notebooks that work perfectly fine unless you pick them up by one corner (as most people would). When you lift the notebook it flexes slightly and the notebook shorts out. Sometimes even a gentle bump will cause this to happen. So far the notebook always starts back up without issue, but this behavior is...inconvenient. It occurred to me that someone familiar with the innards might be able to suggest a little MacGyver fix for this. A little electrical tape in the right spot or something like that. Or perhaps this is a common problem and the answer is here, waiting for me to stumble on the correct keywords. I would appreciate any suggestions Note: It is probably worth mentioning that I have disassembled a Dell notebook before to replace a bluetooth card so I comfortable opening up the systems.

• I can't uncheck the "read-only" attribute from a folder on a Windows Server 2008 machine.

  - by Andrei

  Hello everybody. I have a folder (C:\temp) on a windows server 2008 R2 installation. Initially it has the Read Only attribute checked, but I want to uncheck it. I am able to uncheck it and it even shows me the loading process (it is showing me that it is going through all the subfolders), but after I press OK and I go back to properties, it still remains checked as Read Only. Hope someone has an idea. Thanks. edit: I tried this one, but it doesn't seem to work: http://support.microsoft.com/kb/256614

• How to forward UDP Wake-on-Lan port to broadcast IP with IPTABLES?

  - by Nazgulled

  I'm trying to setup Wake-on-Lan for some of the LAN computers at home and it seems that I need to open a UDP port (7 or 9 being the most common) and forward all requests to the broadcast IP, which in my case is 192.168.1.255. The problem is that my router does not allow me to forward anything to the broadcast IP. I can connect to my router through telnet and it seems this router uses IPTABLES, but I don't know much about it or how to is. Can someone help me out with the proper iptables commands to do what I want? Also, in case it doesn't work, the commands to put everything back would be nice too. One last thing, rebooting the router will keep those manually added iptables entries or I would need to run them every time?

• Google Mail: Import labels when switching from POP3 to IMAP

  - by toobb

  My situation is the following: I have a Google Mail email-address and I have been using this address in Thunderbird fetching the emails with POP3 (the emails also remained on the server and where "archived"). In Thunderbird I organized my emails in folders. Now I want to switch to IMAP (with the same email address), but I want to keep the folder structure I created in Thunderbird. I could create a 2nd account in Thunderbird that uses IMAP, and then move my folders from the old account to the new one. But the problem is, that Google Mail probably does not recognize that it already has these moved emails in "All Mails". I will probably end up with two copies of every email. Does someone has good idea how to deal with that problem? Thank you!

• Acer aspire one d270 can not set brightness

  - by Marko

  I hope you can help me figure out how to set the brightness at my netbook. Following problem appears since I installed ubuntu 11.10 on my acer: I am not able to adjust the brightness by FN Keys nor manually at "systemsettings-display". After searching with google for a while, I found a way via the terminal to adjust it with the folloqing command: "sudo setpci -s 00:02.0 f4.b=7f" ( from 00-9f). That was a major breakthrough for me as I am still new to Linux OS. But still seeking a way to get the FN keys for brightness to work, I kept searching until I found "askubuntu.com". I read through various Questions by other acer users and tried there solutions, but unfortunately none worked out for me. From this thread: fn + arrow keys don't adjust actual brightness on an Acer Aspire 5740 "sudo gedit /etc/X11/xorg.conf". This command did not work because the file was not found. I also used nano instead of gedit, but the file was empty( I think it just created the file since it did not exist). These commands which i found gave me a boot loop and I had to repair ubuntu: sudo gedit /etc/default/grub Change the line GRUB_CMDLINE_LINUX="" into GRUB_CMDLINE_LINUX="acpi_osi=Linux" sudo update-grub From this post Screen Brightness not adjustable for Acer Aspire S3: I tried the solution from the last post, but it did not work either. Does anyone know what I could try? I would appreciate it, if someone could help me out with this. Thanks in advance Netbook specs: CPU: Intel Atom N2600 Memory: 2gb DDR3 Storage: 320 GB HD GPU: Intel GMA 3600

• Replacing an ATA-100 hard drive

  - by Pieter

  I was instructed to replace the hard drive in an old laptop, a Dell Latitude D505. I'm suspecting that there was a head crash when someone moved the laptop while it was turned on. In the specifications, I found this about the hard drive: 30GB ATA-100; (4200RPM); 40GB ATA-100 (5400RPM); 60GB ATA-100 (4200RPM) *Optional 40GB (5400) 2nd HDD Module for media bay I'm familiar with SATA and IDE, but ATA-100 doesn't ring a bell. What do I have to take into account when I go look for a replacement hard drive?

• Can I trust that ZFS is consistent between Linux and FreeBSD?

  - by iconoclast

  I'm planning to build a FreeNAS box sometime soon, but if ZFS on Linux eventually proves to be reliable, I might want to switch, just to have a more familiar OS. So I'm wondering if I can trust that the different implementations of ZFS are compatible. In other words, if I just swap out the boot disk from FreeNAS to Linux or OpenIndiana, can I trust that nothing bad will happen to my data? This may seem like a stupid question--obviously it ought to be compatible--but I'm guessing that ZFS isn't commonly used in cases where drives are moved between computers, so I'm hoping someone can provide a better answer than just "it ought to be".

• How to dealing with the "programming blowhard"?

  - by Peter G.

  (Repost, I posted this in the wrong section before, sorry) So I'm sure everyone has run into this person at one point or another, someone catches wind of your project or idea and initially shows some interest. You get to talking about some of your methods and usually around this time they interject stating how you should use method X instead, or just use library Y. But not as a friendly suggestion, but bordering on a commandment. Often repeating the same advice over and over like a overzealous parrot. Personally, I like to reinvent the wheel when I'm learning, or even just for fun, even if it turns out worse than what's been done before. But this person apparently cannot fathom recreating ANY utility for such purposes, or possibly try something that doesn't strictly follow traditional OOP practices, and will settle for nothing except their sense of perfection, and thus naturally heave their criticism sludge down my ears full force. To top it off, they eventually start justifying their advice (retardation) by listing all the incredibly complex things they've coded single-handedly (usually along the lines of "trust me, I've made/used program X for a long time, blah blah blah"). Now, I'm far from being a programming master, I'm probably not even that good, and as such I value advice and critique, but I think advice/critique has a time and place. There is also a big difference between being helpful and being narcissistic. In the past I probably would have used a somewhat stronger George Carlin style dismissal, but I don't think burning bridges is the best approach anymore. Maybe I'm just an asshole, but do you have any advice on how to deal with this kind of verbal flogging?

  I know this is a dejavu but let me please explain my problem. When booting 13.04 installation media EFI mode get to a black screen with Grub version 2.00-l3ubuntu3 version appears after selecting "install" or "try Ubuntu", there appear error messages: - failure reading sector ... from 'cd0' - you need to load the kernel first I have a Dell Vostro 3560 with Windows 8. I have downloaded and burned ubuntu-13.04-desktop-amd64.iso. Hashes checked. I've booted from the dvd with Secure Boot enabled. The same happens when Secure Boot is disable. When booting with Legacy BIOS, installation starts. I tried Ubuntu without installing and looks OK. BUT, I did not follow the installation because in https://help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_mode there appears "if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too.", which is the case in my computer. I have read many similar questions and the corresponding answers from people in this forum, but till now I haven't found a solution. Could someone help me on this subject? Thanks in advance!

• Are there any good apps for managing vCard vcf files?

  - by Lunatik

  I've just got an Android handset and the import of the SIM contacts from my old phone has left them in a mess; lack of capitalisation, funny character substitutions, odd delimiters etc. I have exported the contacts list as a vcf and while I could manually edit this file, I was really after a desktop app that could do formatting, search & replace etc. There are Android apps that do this but, as much as I like the phone's UI, the prospect of sorting hundreds of contacts via it doesn't exactly fill me with joy. A quick Google just threw up lots of questionable download sites, hoping someone can suggest a lightweight alternative

• ffmpeg trimming video

  - by Dori

  I am having a problem using ffmpeg which is driving me a little mad, so I hope someone can help me out. I have a 13 MPEG-4 .mp4 video of which I am attempting to trim the first two seconds off using ffmpeg and display in an Android app. From the numerous tuts online i am excecuting the following on the command line ffmpeg -i untrimmed_video.mp4 -vcodec copy -ss 2 trimmed_video.mp4 with no luck as it outputs a video of 4-seconds length (i have no idea where its getting 4 from), if i change this to 3 i still get a 4 second video, if i set it to 10 i get unplayable output. if i move the -ss arg to ffmpeg -vcodec copy -i untrimmed_video.mp4 -ss 2 trimmed_video.mp4 i get output the same length as the input, same as if i move to the end. I have tried lots of variations as orders and nothing seems to work, is this a bug, am i doing something wrong?! please help!!!

• Why does my name resolution hit the DNS even with a hosts file entry?

  - by Volomike

  I'm running Ubuntu 10.04.2 LTS Desktop. Being a web developer, naturally I created a "me.com" in my /etc/hosts file. Unfortunately, my name resolution is going out to the DNS before first checking my local hosts entry and I can't figure out why. The end result is that if my /etc/resolv.conf contains "nameserver 127.0.0.1" in there first, then I get a response back in my web browser from me.com (local) within less than a second. But if I don't have that entry, then my response takes sometimes as much as 5 seconds if my ISP is a little slow. The problem was so troublesome that I actually had to file a question here (and someone resolved it) for how to automatically insert that entry into /etc/resolv.conf. But one of the users (@shellaholic) here highly recommended (and commented back and forth with me about it) that I should file this question. Do you know why my workstation's name resolution has to hit the DNS server first before hitting my /etc/hosts file entry? For now, I'm using the resolv.conf trick (see link above).

• How can I make my FireFox Browser AddOn Backwards Compatible?

  - by bwheeler96

  I'm making a firefox browser add-on, and I just got all of the code working fine, but it will only install in FireFox 16, and I want it to be compatible at least from 10+, has anyone dealt with this issue?

• MySQL privileges - DROP tables, not databases

  - by Michal M

  Hi, Can someone help me with privileges here. I need to create a user that can DROP tables within databases but cannot DROP the databases? From what I understand from MySQL docs you cannot simply do this: The DROP privilege enables you to drop (remove) existing databases, tables, and views. Beginning with MySQL 5.1.10, the DROP privilege is also required in order to use the statement ALTER TABLE ... DROP PARTITION on a partitioned table. Beginning with MySQL 5.1.16, the DROP privilege is required for TRUNCATE TABLE (before that, TRUNCATE TABLE requires the DELETE privilege). Any ideas?
