• Is my project a web site or a mobile app?

  - by Evik James

  I am a web developer. I have been developing web sites professionally for 15+ years using ColdFusion, SQL Server, and jQuery. I am doing a project for a client that uses the above technologies. The site has a mobile facet too. For that, I am using jQuery Mobile. The site enables retail store personnel to gather a store customer's preferences using any smart phone or tablet. The store personnel just needs to access a special link via a QR code and a login. Anyone can easily access the site from a PC's browser, too. Some sources suggest that mobile apps must be downloaded and installed using a third party, such as from Google, Amazon, or Apple. Others sources suggest that any information designed for use on mobile device is a mobile app. Regarding the site that is specifically designed for use by mobile devices that extensively uses jQuery Mobile, is this a "web site" or a "mobile app"? What is the "proper" description for this type of site? My customer insists that it is one and not the other. I insist that it is the other and not the one. Can you help me clarify this?

• Firefox- How to change font size of items in bookmarks sidebar

  - by TheClamkinator

  In Windows. (I know I can open Desktop > Properties > Appearance > Advanced [and figure out which item determines it; probably Menu]. But, I don't want other things changed - just the bookmarks. This is because I have so many and I want more of them to display. I did see the question on changing font size of items in folder, on bookmarks toolbar, and sub-folders, etc; But, I'm talking sidebar on firefox, I don't have Google Chrome and I am not a developer.

• getting started as a web developer [closed]

  - by kmote

  I have over 10 years of programming experience building (Windows-based) desktop applications and utilities (VC++, C#, Python). My goal over the next year is to start transitioning to web application development. I want to teach myself the fundamental tools and technologies that would be considered essential for building professional, online, interactive, visually-stunning, data-driven web apps -- the kind described in Google's recently released "Field Guide: Building Great Web Applications". So my question is, what are the primary, most commonly-used technologies that seasoned professionals will need in their tool belt in the coming years? My plan was to start coming up to speed in Javascript, HTML5, & CSS, and then to do a deep dive into ASP.NET and Ajax, along with SQL DBs. (I was surprised to not be able to find a single book at Amazon with a broad, general scope like this, which caused me to start second-guessing this approach.) So, seasoned professionals: am I on the right track? Are there some glaring omissions in my list? Or some unnecessary inclusions? I would welcome any book suggestions along these lines as well.

• String manipulation functions in SQL Server 2000 / 2005

  - by Vipin

  SQL Server provides a range of string manipulation functions. I was aware of most of those in back of the mind, but when I needed to use one, I had to dig it out either from SQL server help file or from google. So, I thought I will list some of the functions which performs some common operations in SQL server. Hope it will be helpful to you all. Len (' String_Expression' ) - returns the length of input String_Expression. Example - Select Len('Vipin') Output - 5 Left ( 'String_Expression', int_characters ) - returns int_characters characters from the left of the String_Expression.     Example - Select Left('Vipin',3), Right('Vipin',3) Output -  Vip,  Pin  LTrim ( 'String_Expression' ) - removes spaces from left of the input 'String_Expression'  RTrim ( 'String_Expression' ) - removes spaces from right of the input 'String_Expression' Note - To removes spaces from both ends of the string_expression use Ltrim and RTrim in conjunction Example - Select LTrim(' Vipin '), RTrim(' Vipin ') , LTrim ( RTrim(' Vipin ')) Output - 'Vipin ' , ' Vipin' , 'Vipin' (Single quote marks ' ' are not part of the SQL output, it's just been included to demonstrate the presence of space at the end of string.) Substring ( 'String_Expression' , int_start , int_length ) - this function returns the part of string_expression. Right ( 'String_Expression', int_characters ) - returns int_characters characters from the right of the String_Expression.

• How to solve ATI Radeon 7670M/ Intel HD Switchable Graphics recurring BSOD error?

  - by Ashin Mandal

  I recently bought a VAIO E Series laptop with an ATI Radeon 7670M and Intel HD Switchable Graphics. Around about one month ago, my computer started shutting down with atikmpag.sys blue screen error and the frequency of the errors kept on increasing with time. I am really worried about my VGA Adapter and whether or not it's gone bad. It's a 3 month old laptop! I searched on Google about atikmpag.sys BSOD and most of them suggested that my driver probably needs to be updated. I searched the Sony website and also the ATI website, I did have the latest drivers installed. Yet, I uninstalled the driver and installed it back again. But blue screens just keep coming back again and again. It generally happens more frequently when I have a video running and have paused it to do something else. I hope it's a driver issue!

• Trojan infection help please

  - by brandon

  Hey, I was browsing some websites and somehow obtained a trojan through some sort of silent download. Google Chrome started acting funny and wouldn't load web pages and neither would internet explorer. Only Firefox worked. I rebooted my computer and as usual logged into my email account as well as my bank account online completely forgetting about the infection. Could my information have been sent to the person or people or wrote the trojan? I downloaded Zone Alarm and took care of the issue, I'm just worried about when I absentmindedly logged into my email account and bank account online while I was infected.

• PHP + IIS7 + X64 OS (Windows 7 or Server 2008)

  - by Eric

  I'm going to answer my own question here, but I thought this might be important enough to post so that it would be indexed for the next person who runs into my situation. Problem: I can not seem to get PHP code to execute on a x64 bit version ofIIS7, whether it be in my desktop, Windows 7, or the application's final destination on Windows Server 2008. Every time I try and look at a test php document to confirm installation, I only see the source code. I've followed the documentation from PHP, from iis.net, blogs, howtos, just about anywhere I can find that Google would send me. I tried the web installer, tried manual installations instead of the MSI, tried version 5.3.5, tried version 5.2.17, but no matter what, the code would never execute. I even tried registering .eric files with PHP FastCGI Module, but same result, php source code only.

  - by piquadrat

  I have to access my home router's web interface on port 80. Unfortunately, the only way into the network I have at the moment is SSH to another machine on the same network. me ---|---SSH Box----Home Router My Google foo seems to have abandoned me, I couldn't didn't find anything helpful. Any ideas? Thanks! To clarify: I'm not at home right now. I do however have access to one machine on the network (a QNAP NAS) over SSH. I need to access the home router web interface on port 80 from my notebook which is outside of the home network.

• Has ec2 made self-hosting possible for 'amateur' sysadmins possible?

  - by Blankman

  I'm a developer, and it seems ec2 has made it possible for a amateur sysadmin like me to setup and maintain a fairly large set of servers. Now I don't mean to undermine real sys admins, as I know the value of them but what I am trying to get at is that someone like me can setup and maintain a cluster of servers (front end web servers, with some db servers) using tools like ec2 and capistrano with the help of google. Now this isn't something I would do as a long term thing, but as a startup, one-man operation, I think I can pull this off until business takes off and I can hire this important role out. With ec2, I get my firewall, so I basically open up port 80 on my public facing server, which will run haproxy and route requests to my cluster of servers. Ofcourse I am simplifying the setup, but just want a feel for what you guys think about my perception. My application is a web application, that will be runing Ruby on rails (passenger) and talking to mysql or postgresql.

• Reocurring unpack failed on git repo improted from svn

  - by xavier

  I have a git repo created from svn with git-svn. Everything converted just fine, but from time to time, when I try to git push, I get: error: unpack failed: unpack-objects abnormal exit Other repos on our server (created from scratch or imported from svn) work fine. The solution is usually to unstage, commit and push files one by one, modify the one that fails (e.g. add a whitespace or something) and commit it once again. It's obviously very irritating, for big commits it's a productivity killer - and requires a lot of server pushes. I'd be grateful for any suggestions on where to look, I couldn't google anything up.

• Two views of Federation: inside out, and outside in

  - by Darin Pendergraft

  IDM customers that I speak to have spent a lot of time thinking about enterprise SSO - asking your employees to log in to multiple systems, each with distinct hard to guess (translation: hard to remember) passwords that fit the corporate security policy for length and complexity is a strategy that is just begging for a lot of help-desk password reset calls. So forward thinking organizations have implemented SSO for as many systems as possible. With the mix of Enterprise Apps moving to the cloud, it makes sense to continue this SSO strategy by Federating with those cloud apps and services.  Organizations maintain control, since employee access to the externally hosted apps is provided via the enterprise account.  If the employee leaves, their access to the cloud app is terminated when their enterprise account is disabled.  The employees don't have to remember another username and password - so life is good. From the outside in - I am excited about the increasing use of Social Sign-on - or BYOI (Bring your own Identity).  The convenience of single-sign on is extended to customers/users/prospects when organizations enable access to business services using a social ID.  The last thing I want when visiting a website or blog is to create another account.  So using my Google or Twitter ID is a very nice quick way to get access without having to go through a registration process that creates another username/password that I have to try to remember. The convenience of not having to maintain multiple passwords is obvious, whether you are an employee or customer - and the security benefit of not having lots of passwords to lose or forget is there as well. Are enterprises allowing employees to use their personal (social) IDs for enterprise apps?  Not yet, but we are moving in the right direction, and we will get there some day.

• How can I see the metadata of an ISO file?

  - by netvope

  I have been searching for the list of metadata field of an ISO file on Google but couldn't find anything. That made me think that there isn't any metadata in an ISO file, just the files content and their properties. However, today I find in ImgBurn that there is a field called Imp ID, which typically contains the software used to create the ISO file. I'm not sure if it is specific to the UDF and/or CDFS filesystem. What are the other possible metadata fields in an ISO file? What software may I use to see them?

• OSX - Update "Java for OS X 2012-002" is not mentioned on support.apple.com, is this ok?

  - by snies

  Straight after installing "Java for OS X 2012-001" Software Update asks me to install "Java for OS X 2012-002", which has the exact same size (66.6 MB) and description (including the same two links: HT5055 and HT1222) as the former, which strikes me as odd. The "Java for OS X 2012-001" is described on the apple support pages, but the "Java for OS X 2012-002" is not mentioned anywhere. Also searching on google does not yield any usable results. What is your opinon? Am i paranoid? Did you also see this update?

• Installed IE8 & SP3 on XP now I can't HTTPS from any browser

  - by Kevin

  The computer is Windows XP Professional SP3 with IE8. On the Tools Options Connections the "Settings" is GRAYED OUT (I am an admin on the machine) Any browsing of https:// addresses results in IE displaying the following: "this program cannot display the web page" After installing an alternate browser and trying the same https:// address I get a similar error message. I have tried using Compatibility View Settings to for all web pages and this has no effect on the problem. HTTP addresses work fine, I can PING sites such as google.com without issue. Question: What could be preventing me from getting at the settings to check to see if I'm using a proxy? What else could be preventing HTTPS access?

• .bashrc doesn't get sourced after su'ing to root

  - by Ian Dunn

  I've got a CentOS 5.6 VPS and both root and my normal user account have identical copies of a .bashrc file in their home directories. The file contains a few basic aliases, etc. If I login to root, root's copy gets sourced. If I login to myuser, myuser's copy gets sourced If I su to root after logging into myuser, then all the aliases, etc inside myuser's copy get removed, and root's copy doesn't get sourced. If I then manually source root's copy, the command completes without any errors, but none of the aliases's etc get applied. I've searched Google and Server Fault, but haven't found any solutions. Does anyone know how to fix that?

• snapping an angle to the closest cardinal direction

  - by Josh E

  I'm developing a 2D sprite-based game, and I'm finding that I'm having trouble with making the sprites rotate correctly. In a nutshell, I've got spritesheets for each of 5 directions (the other 3 come from just flipping the sprite horizontally), and I need to clamp the velocity/rotation of the sprite to one of those directions. My sprite class has a pre-computed list of radians corresponding to the cardinal directions like this: protected readonly List<float> CardinalDirections = new List<float> { MathHelper.PiOver4, MathHelper.PiOver2, MathHelper.PiOver2 + MathHelper.PiOver4, MathHelper.Pi, -MathHelper.PiOver4, -MathHelper.PiOver2, -MathHelper.PiOver2 + -MathHelper.PiOver4, -MathHelper.Pi, }; Here's the positional update code: if (velocity == Vector2.Zero) return; var rot = ((float)Math.Atan2(velocity.Y, velocity.X)); TurretRotation = SnapPositionToGrid(rot); var snappedX = (float)Math.Cos(TurretRotation); var snappedY = (float)Math.Sin(TurretRotation); var rotVector = new Vector2(snappedX, snappedY); velocity *= rotVector; //...snip private float SnapPositionToGrid(float rotationToSnap) { if (rotationToSnap == 0) return 0.0f; var targetRotation = CardinalDirections.First(x => (x - rotationToSnap >= -0.01 && x - rotationToSnap <= 0.01)); return (float)Math.Round(targetRotation, 3); } What am I doing wrong here? I know that the SnapPositionToGrid method is far from what it needs to be - the .First(..) call is on purpose so that it throws on no match, but I have no idea how I would go about accomplishing this, and unfortunately, Google hasn't helped too much either. Am I thinking about this the wrong way, or is the answer staring at me in the face?

• Windows XP Pro 'Connect to' logon box greyed out with Guest

  - by HaydnWVN

  Have a machine i've just nuked and paved to be used in a public enviroment, yet still connected to a Workgroup. Would like it to prompt for a logon when accessing any of the network shares as different departments will be using it. It does prompt for a login but the username field is greyed out. Have disabled simple file sharing, disabled guest account, changed Local Security Policies (Network access Sharing and Security model to 'classic') all to no avail. A google around has lots of other people with the same issues, lots of 'fixes' with very few feedback. Of course none of these work for me! :)

• How to Use Vim-Style Keyboard Shortcuts for OS X Tab Navigation

  - by The Geek

  After switching to OS X when I got a new MacBook Air, one of the first things I needed to duplicate was my extremely customized AutoHotkey setup — the most important of which is using the J and K keys to navigate throughout tabbed windows easily. Yeah, I’m a Vim user. I’ve never been a fan of having to use CTRL + TAB to switch from one tab to the next — to start with, you have to move your hands from the home row, and it’s awkward, and why should I have to do that just because somebody decided that keyboard shortcut before tabs became popular? If you think about it, if tabbed browsers were popular back when keyboard shortcuts were being invented, they would have definitely reserved some of the good shortcuts for switching tabs. On Windows, I’ve always used an AutoHotkey script to make things the way I wanted it:  ALT + J and ALT + K for selecting previous and next tabs. Once you get used to it, it’s extremely awesome, and so much faster than using CTRL + TAB. Of course, I also hacked CTRL + T and CTRL + W into ALT + T and ALT + W so I could open new tabs and close them without moving my hands from the home row. Over on OS X, it turns out that it’s incredibly simple and easy to use CMD + J and CMD + K for next/previous tab navigation, and it works in most applications that support tabs, like Terminal, Safari, or Google Chrome.

• Mozilla Persona to the login rescue?

  - by Matt Watson

  A lot of website now allow us to login or create accounts via OAuth or OpenID. We can use our Facebook, Twitter, Google, Windows Live account and others. The problem with a lot of these is we have to have allow the websites to then have access to our account and profile data that they shouldn't really have. Below is a Twitter authorization screen for example when signing in via Technorati. Now Technorati can follow new people, update my profile and post tweets? All I wanted to do was login to Technorati.com to comment on a post!Mozilla has just released their new solution for this called Persona. First thought is oh great another solution! But they are actually providing something a little different and better. It is based on an email address and isn't linked to anything like our personal social networks or their information. Persona only exists to help with logging in to websites. No loose strings attached.Persona is based on a new standard called BrowserID and you can read more about it here:How BrowserID Works.  The goal is to integrate BrowserID in to the browser at a deeper level so no password entry is required at all. You can tell your web browser to just auto sign in for you. I am really hoping this takes off and will look at implementing it in current projects! I would recommend researching it and lets hope it or something like it becomes a wide spread reality in the future.

• Make Safari 5's location bar more like Omnibox or AwesomeBar

  - by Lri

  When searching for history or favorites, the search phrase has to be an exact substring of the URL or title. For example super awesome wouldn't match this page. Can the criteria be made more liberal? When an item that was matched by its title is selected from the suggestion list, the title is filled in in place of the URL. The filled in part sometimes starts from the middle of a URL or a title. Can either of these behaviors be changed? Can you redirect unresolved addresses to the default search engine or a custom URL? In Firefox you can go to about:config and set keyword.URL to http://www.google.com/search?btnI&q=. Can you remove or hide the web search field? In Camino, Cruz, and Fluid it can be resized to zero width.

• how to make SFTP work on Windows

  - by cyberkiwi

  What is the correct way to set up sshwindows for SSH key authentication? Does the user need to be created in Windows first or can a login be inserted into passwd without a Windows equivalent? I've searched on Google and have tried the tutorials and quick start guides. So far, exactly 0 have worked. None pointed out that to work in Windows 2008 R2, you need to change the properties of cygrunsrv.exe to "Windows XP SP3" compability mode to even get past the service startup "error 1067". Although it is running, no amount of configuration allowed me to log on to the SFTP server, even though I tried (from another machine): same user account added using "mkpasswd" + windows password same user account added using "mkpasswd" + public ssh key (added to /home/theuser/.ssh) On Windows 2003 R2 (a different attempt), the service would crash every time it started up. Some links I went through http://pigtail.net/LRP/printsrv/cygwin-sshd.html http://forevergeeks.com/how-to-setup-a-secure-ftp-sftp-site-with-openssh-on-windows/ http://support.moonpoint.com/os/windows/server2003/openssh-service-not-starting.html

• How to Enable Priority Inbox on Android (and Setup Important-Only Notifications)

  - by The Geek

  Yesterday Google released an updated Gmail application for Android 2.2 phones that supports the Priority Inbox feature—and more importantly, allows you to change your notifications to only alert you for important email. Let’s take a look. Note: If you’ve never used Priority Inbox, you should really give it a try—it rearranges your email into what is and isn’t important, and you can customize how it classifies messages easily. The idea is that it learns over time, so if you send a lot of emails back and forth with somebody, it will know that they are probably important—you can manually adjust the settings as well. To update the Gmail application, you’ll want to head into the Market and access Menu –> Downloads, where you should see Gmail in the list, and it should let you update from there. If you don’t see an update, you’re either not running Android 2.2, or it has already updated automatically Latest Features How-To Geek ETC The 50 Best Registry Hacks that Make Windows Better The How-To Geek Holiday Gift Guide (Geeky Stuff We Like) LCD?

• Dedicated Servers: Is one better then two for LAMP pseudo HA setup? [closed]

  - by bikedorkseattle

  Possible Duplicate: How to find web hosting that meets my requirements? I know there are zillions of commentary about hosting out there, but I haven't read much about this. Our current well known host is having too many problems, the hardware we are on it subpar, and I'm ready to leave. A day of downtime can cost as much as our monthly hosting bill. A month of bad performance is just killing us right now, user and google wise. I'm wondering about running two dedicated boxes for LAMP, one running as the primary Nginx/Apache (proxy pass), and the other as the MySQL box. Running a single box scares the bejesus out of me because who knows how long it will take anyone to fix a raid card or whatever. The idea is to set this up using some sort of failover system using pacemaker and heartbeat. If one server goes down the other can take over for the other running both web and db. There are some good articles over at Linode about this. I have a few DBs that are 1GB+ and would like to load them into memory. Because of this, I'm shying away from a Linode HA setup because for the price I could do it with two dedicated like I described. Am I mad or an idiot? What are people out there doing for pseodu high availability good performance setups under $400/month? I'm a webmaster; I do a lot of things none of it that well :)

• Why do most routers not include local DNS?

  - by user785194

  I need to change my firewall/router, and I'd prefer something with built-in DNS to resolve queries on the local subnets. I've got a mixed Linux/Windows system, often with only one computer turned on, and I frequently have problems resolving local names. I don't want to keep a Linux box permanently on just for DNS, and I'd prefer to have DNS in my router appliance, which is always on. I search Google for this occasionally but never find anything. You always get the obvious answers - it's not possible, put everything in /etc/hosts, NetBIOS, dedicated box, etc. So what am I missing? Why don't "cheap" routers let you do this? I'm pretty sure that Cisco kit does this. Almost all cheap routers will let you do MAC address reservation, to let them assign static IP addresses for DHCP. So why can't they simply do DNS as well for everything on the local subnets, just passing through remote domains to the ISP?

• block access to certain website types

  - by frustrated teacher

  Need to block access to certain website types without listing each URL to block. Students at secondary school are going to porn sites. Need to be able to block all such access without having to list each possible site URL. Having the Content -- Ratings tab set to None for all categories on the ratings files listed on my computers does not prevent access. Unchecking users may access sites with no rating, even with the security settings set to High, still allows the porn sites to come up. If that is checked, then ONLY listed sites can open and students would not be able to do any research via google, for example. I would rather not have to continue checking each computer and blocking sites as they find them.
