• Best Option for Creating A Small Church Website

  - by Jim

  I've been asked to create a website for a small church. Their prior site was hosted on geocities which is no longer. They are not looking for anything robust, just an informational site with a calendar and maybe a contact form. The church would also like to be able to administer the site with little technical know-how. Cost is also an issue. Given these requirements, something like sites.google.com seems like a good option. However, my main concern is that Sites will suffer the same fate as geocities. It is definitely not a flagship Google product. Are there other good alternatives that fit the requirements?

• Broke my sudoers password, how do I reset it without using sudo?

  - by Eric Dand

  I thought it would be a good idea to finally take the password off my little netbook since it has never actually been of any use, and has mostly just slowed down . But when I went to change my password, there wasn't even an option to make it blank, and any attempt to make it a few easy characters was met with "Password too weak". So I did what any good geek would do and popped open the terminal, read the manual entry for passwd and quickly used the -d option to remove the password from my account. It all went well for a couple days (I even managed to also make my keychain password blank) until I tried to update the thing. My sudoers password is not blank, and it's not my old password. I have no idea what it is. How do I reset it (or even better, make it blank) without the use of the sudo command?

• Getting Started

  - by andyleonard

  Every once in a while someone asks me, “How does one go from being just-a-developer to presenting at conferences?” When I hear this question, a little voice inside my head asks, “Why are they asking you ?” And then another voice says, “You idiot, it’s because you made that trip from just-a-developer to conference speaker.” So now we have an admission that I hear voices in my head. (Is anyone surprised? I thought not. Moving on…) A disclaimer: what worked for me may not work for you. I can hear you...(read more)

• LL(8) and left-recursion

  - by Peregring-lk

  I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?

• SEO tool is telling me title, description and keywords don't exist, but they do. Where is the problem?

  - by DaveDev

  I'm using the following tool to analyse how 'optimal' a site that I'm working on is for search engines: http://tools.seobook.com/general/spider-test/ I enter the URL for the site - http://ftmsuat.moneymate.com - into the search bar, and it returns a breakdown of the contents of the page. I'm a little confused by what I see though. According to the results, the page doesn't have a title, description or keywords. But if you check the source of the page, those elements are definitely there. So I'm wondering now, which is wrong? seobook.com or my page?

• Ubuntu 12.04 wont install on Macbook

  - by user92325

  I've installed Ubuntu on my Macbook before but something went wrong with the updater. So, I had to backup my HDD and format it and reinstall OS X Lion. But here's the thing: Ever since I re-installed my OS I've been trying to get Ubuntu back on the HDD. I partitioned it to 40 GB and set the file system to Ext4. I also recently created a swap partition too and it seems to install correctly. After i installed rEFIt it just has this cute little penguin sitting there. I rebooted and tried to go back to Ubuntu and the penguin still shows up but this time a black screen pops up and it asks me to insert a bootable device and press any key. I'm not sure why this is happening. This is probably the 5th time I've tried to install it. I've even used a different Ubuntu ISO but it still won't boot after the installation.

• Is there a better way to have a two column website with header and footer, equal height columns and stretchy column widths? [closed]

  - by Seamus

  I wrote a website a while ago that is a little messy in how it does things. I used this CSS template and this equal height columns trick. I have not one but two container divs and I can't remember what they're doing. So I'm thinking of re structuring the thing from scratch, and possibly making use of the more "semantic" html5 tags like <nav> and so on at the same time. The question is: is there a better way to achieve a site structure with these properties: 2 equal height main columns (with widths as percentages of the available real estate, not explicitly stated) both a header and footer element that stretch the whole width of the total of the two main columns That allows the use of semantic html5 tags instead of meaningless divs

• 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.

• returning null vs returning zero, which would be better?

  - by Dark Star1

  I inherited a project that I am managing and having to maintain pending the redevelopment of the code base. At the moment I am being tasked with adding little feature all over the place and have gotten into the habit of returning null instead of zero in parts of the code where I am working on. The problem is we have a client that is using this code and parts of code that require data from my implemented features recieve a null and dump the stack trace in UI. I would like to avoid this entirely from my input but without the nullPointer exceptions there's the potential that errors would be introduced into the client's data which may go un-noticed. Usually I would have come up with my own error notification system but I have never inherited a project before. so I am unsure whether to continue down this path. I still believe that the stack dump is preferable to un-noticed data corruption/inaccuracies.

• Is it possible to power down my external via the eject button?

  - by beanaroo

  I'm trying to convert from Windows 7 to Ubuntu 12.10 with Gnome 3.6. Using the notification area's eject icon, I notice the partition is unmounted but the drive is still powered and spinning... I understand the latter can be taken care of by means of udisks --detach /dev/sdb I really don't want to have to run a command everytime I eject. Windows does the whole process when ejecting a medium via the systray. Is there a way I could add in the command to the eject button? Is there an appropriate place I could file a feature request? Little things like this are making it hard for me to swap back over to Linux. Thanks for the support!

• Finding Internship Opportunities

  - by mbreedlove

  I am a senior in high school majoring in Computer Science next fall. This summer, I would like to intern at a company relevant to my interests of investment banking and software engineering. What would be some possible ways to find openings? How should I contact them? (E-mail, phone, etc.) Should I prepare and submit a CV? I feel it might be a little dull as it would have no experience or references. After contacting someone about an internship, should I follow up, or just wait for them to contact me? Is there anything else I should do or be aware of?

• script shortcut to open two files in gedit as sudo

  - by Sam

  I want to double click a file on my desktop, and have two files be opened in gedit as sudo. Whenever I'm making a new website, I need to open /etc/hosts /etc/apache2/sites-enabled/000-default.conf as sudo. At the moment this means opening the terminal, runing sudo gedit then opening each file manually. I want to streamline this part of my workflow. On windows I had wrote a little bash script which worked nicely. How can I do the same in ubuntu? So far in my searches I've come across ways of adding a shortcut to the file browser, and similar things, but not exactly what I want. I have tried creating a desktop launcher, but can't see how to make it run as sudo.

• Connect Digest : 2011-06-27

  - by AaronBertrand

  Sorry I have fallen off the Connect Digest wagon for the past few weeks; been a little swamped since returning from SQLCruise Alaska. Not sure I'll be able to assemble a digest every week, but I'll certainly try to keep a steady pace. This week I wanted to highlight a few suggestions around indexed views. With the coming of SQL Server code-named "Denali" we will be pushed toward the new columnstore index as an alternative to indexed views. But this won't be for all cases, and it likely won't be available...(read more)

• Building dynamic bounding box hierachies.

  - by adivasile

  I've been reading about collision detection and I saw that the first part was a coarse detection which generates possible contacts using bounding box hierarchies. I understand the concept of splitting up your objects in groups, to speed up the detection phase, but I'm a little confused on how do you actually build the hierachy, more so on what criteria is used to group them together. Do I iterate through all the objects in the scene, and check the distance between them to see where they should be inserted in the tree? Do you know some resources that may shed some light on this topic for me?

• Blank desktop after login

  - by Alex

  Today my 14.04 updated itself not requiring a reboot. After a while I rebooted because of other reasons and then I was pleasantly surprised by a blank screen. I have tried everything I could think about including Reinstalled compiz, unity, ubuntu-desktop, xorg Reinstalled and then removed the nvidia driver So far nothing has worked. Except for one little thing: my cairo-dock is showing. And that's all. I tried with Unity doesn't load, no Launcher, no Dash appears, but none of the answers there helped me. I also tried removing my ~/.Xauthority file and it still doesn't work. Does anybody know what else I could try? UPDATE: sudo dpkg-reconfigure xserver-xorg sudo service lightdm stop sudo service lightdm start When I run that code and then login again the icons on the desktop are displayed but the menu and the launcher are still not there. Also, when I try to run an application from CTRL + ALT + F1 such as dconf reset -f /org/compiz/ it says Cannot autolaunch D-Bus without X11 $DISPLAY I can only run applications with export DISPLAY=:0

• Why is 2^16 a "special" number?

  - by javamonkey79

  OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

• How can I customize my bootloader to make it prettier?

  - by Matthew

  I hate how when I turn on the computer it just (after the hp logo, which I hate having also), shows white text on a black background. I'm wondering if there's easy ways to customize this (I'm choosing between Windows 7 and two separate Ubuntu 10.10 installs). I've read a little about some complicated ways to do this, but is there not some simpler ways by installing a package on ubuntu or something? I don't want to hack a bunch of code together to get a simple effect. I'm hoping for actual images and having like the windows 7 logo and ubuntu logo to choose from. Ideas?

• Is an in-app purchase required to unlock game in order to bypass pirating acceptable?

  - by digitaljoel

  I'm considering writing a mobile game and looking at distribution. The game will have a server requirement, which means I will have to pay for bandwidth, hosting, processor time, etc. Because of that I'll need to make at least a little money off this thing. According to the press piracy is rampant in the android community. To get around this, I'm thinking of implementing a simple model where the game is free, perhaps allowing play for X number of turns or something, and then requiring an in-app purchase to continue to play. I would clearly explain this in the app description, and the in-app purchase would be managed per account so it would be linked to your google play account so you wouldn't have to re-purchase every time you get a new device. Would gamers accept this model or see it as unreasonable?

• How to remove non-working session entries in LightDM?

  - by Lexalt

  I recently added Cairo Dock to my GNOME Shell in 11.10. Cairo Dock is GREAT, but I'm left with one little problem that I'd like to fix: after installing Cairo Dock, LightDM includes two extraneous entries to non-working desktops. (The entries to working desktops remain unaffected, so I guess I could just ignore the extraneous entries, but...) So I'd like to remove/edit the extraneous entries in LightDM. I've looked and looked for discussions on how to do so, but haven't had much luck. Any suggestions on how to go about editing the login menu in 11.10?

• wget not respecting my robots.txt. Is there an interceptor?

  - by Jane Wilkie

  I have a website where I post csv files as a free service. Recently I have noticed that wget and libwww have been scraping pretty hard and I was wondering how to circumvent that even if only a little. I have implemented a robots.txt policy. I posted it below.. User-agent: wget Disallow: / User-agent: libwww Disallow: / User-agent: * Disallow: / Issuing a wget from my totally independent ubuntu box shows that wget against my server just doesn't seem to work like so.... http://myserver.com/file.csv Anyway I don't mind people just grabbing the info, I just want to implement some sort of flood control, like a wrapper or an interceptor. Does anyone have a thought about this or could point me in the direction of a resource. I realize that it might not even be possible. Just after some ideas. Janie

• New to iPhone Development - iOS5 Storyboard

  - by Peter

  I'm new here and pretty new to iOS development. My question is basically, should I learn the old school development methods or just learn how to do things using the latest tools (i.e. Storyboard)? I've had a go with the Storyboard feature of XCode 4.2 and it's very powerful. My only concern is that it requires iOS 5. I don't mind learning the old way of doing things but I've been having trouble finding tutorials/examples for XCode 4.2 that don't use the storyboard. An example would be the with my trouble finding a good tutorial on how to embed a Navigation Controller into a TabBarController. A lot of the material out there seems to be for older version of XCode. Using the storyboard I'm able to set this up with seconds but still haven't managed to get it working without it. So in short :) would you guys suggest I continue my project using the Storyboard or make the extra effort to do things a little more manually?

• How do global cancel/exit commands work in bash?

  - by SecurityGate

  As I have done multiple times before, I've written bash scripts, and just general commands that go nowhere. They just blink the little command line cursor at me for infinity until I control+C the command. When I do cancel the command, what exactly is going on when I do this? Am I somehow stopping and killing the current PID I'm working on? Does it jump to a different run-level and execute something to terminate the command? On a slightly different note, I've never been able to figure out how to set up something like this in a script or program I've worked on. Since I mostly program in Ruby, can I setup something like a certain key press stops the program? Every time I've looked into doing something similar, I always end up getting hung up when it comes to user input, whether that is a loop waiting for a condition, or something like this: def Break() user_break = gets.strip end def Main() Function1() Break() Function2() Break() [...] end It seems and is incredibly bulky, and definitely isn't easily scaled up or down.

• How much C/C++ knowledge is needed for Objective-C/iPhone development?

  - by BFree

  First, a little background. I'm a .Net developer (C#) and have over 5 years experience in both web development and desktop applications. I've been wanting to look into iPhone development for some time now, but for one reason or another always got side tracked. I finally have a potential project on the horizon, and I'm now going full steam ahead learning this stuff. My question is this: I haven't done any C/C++ programming since my schooling days, I've been living in managed land ever since. How much knowledge if any is needed to be successful as an iOS developer? Obviously memory management is something that I'll have to be conscious about (although with iOS 5 there seems to be something called ARC which should make my life easier), but what else? I'm not just talking about the C API (for example, in order to get the sin of a number, I call the sin() function), that's what Google is for. I'm talking about fundamental C/C++ idioms that the average C# developer is unaware of.
