• What notes should I be taking, if any, at the beginning of a project?

  - by Justin R.

  I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

• How to limit server to specific IP addresses with mod_authz_host?

  - by BeeDog

  Hi! I am very new to this area, so please bear with me. :) Right now I am running an Apache HTTP server on my setup, a very basic configuration. The website hosted on it is accessible from anywhere, and I want to limit the access to a specific IP address range. I've looked into this and I found that one Apache module called mod_authz_host handles this. http://httpd.apache.org/docs/2.2/mod/mod_authz_host.html The problem is, I haven't managed to find documentation that explains well how to actually do the stuff. How do I actually make sure only a certain range of IP addresses can access my site/server? The machine is running Ubuntu Server 10.10, the web files are stored in /var/www/, the apache2 daemon has its stuff stored in /etc/apache2/ and /usr/lib/apache2/modules/*. Thanks in advance, and sorry if this is a stupid question!

• Deciding to use VM or native install for new hardware

  - by Billy Moon

  I have a Ubuntu 10.10 installation running on hardware. I upgraded the hardware, and am planning to move the system over. Whilst reading the many various ways to do this, I came across tools for making a virtual machine out of a hardware installation. I think this might make managing my server easier in the future if I run it as a virtual machine. Also, I will be able to easily split responsibilities of my server, for example running MySQL on a separate virtual machine hosted on the same physical machine. Is it a good idea to install my production server as a virtual machine inside another thin server installation? What are the pros/cons and pitfalls?

• Getting a list of all phone contacts?

  - by pcm2a

  Simple enough question. I need to know the best way to get the same list of contacts that show up when a user presses the Contacts button. You would think something like this would work: //For Contacts Intent pickIntent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); //For Phones Intent pickIntent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); The problem is that does not include secondary google accounts or Exchange contacts. By secondary accounts, in Android you can add additional gmail accounts to have the mail/contacts synced. The above intent will not list those additional contacts. I am also told that on the HTC Desire you can add contacts to the phone that do not get synced up to Google. These contacts also do not show up. So how do I get a real list of contacts so I can create my own list activity that works properly where the Google intent does not.

• Background task in mobile phone to access a secure element and a web server

  - by Splryxx

  Is it possible in a GSM mobile phone OS (e.g. Android, Win Mo, Symbian, etc.) to have some kind of background task or application able to exchange data at the same time with a web server and a secure element of the mobile? The purpose if for the web server to be able to push APDUs to the secure element (an retrieve response APDUs) without activating the IHM of the mobile. NB: I know that this is possible when the secure element is the one managing the GSM baseband, for example using BIP as described in Ulysse specifications. My question is only when using another secure element (e.g. Java Card in a microSD).

• How to make a Windows Mobile based WinForms .Net application easily changeable?

  - by Arthur

  I need to build a Win Mobile WinForms .Net application that once developed will be easy to morph or adjust to new user requirements quickly (including changes in GUI). The main objective is to minimize the development time (development to production roll-out effort). Also, a nice thing to have is to be able to test it in an automated way. The application must be able to: 1) Persist state (may use a local database); 2) Sync data across (via Radio or WiFi); 3) Exchange info with a desktop PC or a central server;

• Whats the best way to deal with backups for my php/mysql application

  - by spirytus

  I'm creating php application for my client and now thinking what would be the best way to do backups, automatically if possible? I don't have much experience in this area and in case something goes wrong, or if I need to migrate, I would like to have fast way of getting it all back online. I understand "something goes wrong" is a very wide term, but lets say that someone hacks my site and wipes out database and all the files. My app. is written in php/mysql and I got access to cpanel (hosted with justhost.com if that makes any difference :). I used Joomla and it has JoomlaPack that does complete backup almost automatically and in case site fails, its easy to revert, or migrate if necessary. Is there anything like that for my configuration that would make reverting/migration, easy?

• Security considerations when giving access to SQL Server db for a web application

  - by rem

  I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

• SharePoint 2010 MySites - Host on separate servers

  - by Chris W

  We're playing with the SP 2010 Beta ahead of a planned deployment later this year in an academic environment. We anticipate that the majority of traffic will be through MySites when everything is provisioned so we're looking at how we can plan our SP topology to scale nicely. An initial thought is to run the main portal on one server, host "Student" MySites on one server and "Staff" on another. Is it acutally possible to do this easily or are we going down a bad path? Specifically - can we have 2 different MySites site collections, each hosted on a dedicated server? If so, can we configure SharePoint to work out from the users's logon account type of user they are and route them to the correct server?

• What is the best way to reject messages with the same body in AMQ queue?

  - by archer

  I have a single AMQ queue that receives simple messages with string body. Consider I'm sending CLSIDs as message bodies. CLSIDs could be not unique, but I'd like to reject all messages with not unique bodies and keep only single instance of such messages in the queue. Is there any simple way to do it? Currently I'm using a workaround. Messages from the queue are consumed by some processor that tries to insert bodies into a simple DB table with UNIQUE constraint applied to message_body field. If processor inserts the messages succesfuly - it's assigned to exchange.out.body and sent to other queue. If ConstraintViolationException is thrown - nothing is resent to other queue. I would like to know does AMQ support something similar out of the box?

• Cloud storage services offering one-time download links? [closed]

  - by TARehman

  Is anyone aware of consumer-targeted cloud storage services that allow users to generate a one-time download link for hosted files? Case in point: I have an encrypted container with some documents I need to send to a vendor. I would prefer to give them a one-time download link, so that I know when they have accessed the file, and then inform them of the passphrase by phone. I have heard that MediaFire offers 1-time links, but that they are buried in tons of advertising. At the moment, I'm not sure that I consider MediaFire fully legitimate; I'm more interested in solutions with Google Drive, Box.net, DropBox, etc.

• Run Photoshop on VM (virtual machine) to increase calculation power, without violating the licence agreement (EULA)

  - by mecplusultra

  A question concerning the possibility to run Photoshop as VM without violating the licence agreement (EULA) : My Adobe Photoshop is bloody slow, nd sometimes I need to launch thousands of image calculations that have to use hundreds of PSD templates. I want to increase my Photoshop calculation power by creating non-persistent virtual machines on my hosted server. Each VMm would only alive for a few seconds, just enough time to deliver the calculated file. Is this a violation of the EULA? I must clarify that I'm the only one to access my non persistent VMs.

• How to measure that a host is good for users in Egypt ?

  - by Sherif Buzz

  Hi all, I currently have a site that's hosted in Texas. The majority of my users are from Egypt and I'm a bit concerned that the current hosting is not the optimal in terms of performance. The site is not slow but for how can I know if, for example, hosting it in Europe or Asia is better ? To clarify I need to know there is a way that I can test different hosting options - for example how can I test the average response time between Egypt and a host in Texas, the average response time between Egypt and a host in the UK ?

• What domain names are served by a host?

  - by pjmorse

  For a set of VPSes operated by my company, I'd like to get a list of domain names hosted by each. The list of names has grown in an ad-hoc way for a few years. Is there a simple way to query the Apache and/or Nginx configurations to see what domains the server answers to on port 80? It is safe to assume (a) that I have sudo on these systems, and (b) they aren't using wildcards, although a solution which acknowledged that a wildcard was in use would be useful too if it also provided a list of explicit domains.

• Hosting company that does Linux VPS and MS SQL

  - by danielmcq

  I'm looking for hosted solutions but there are so many companies that finding the right one using a Google search is a bit overwhelming. Ideally I would like a hosting company which has following options: -Linux VPSs - Individual VPSs should be fairly cheap since I plan on putting one or two services per VPS i.e web server on one (httpd and ColdFusion), an SVN server on another, etc. -Managed MS SQL databases - My company already has data in MS SQL databases and a lot of ColdFusion code written that has MS SQL specific commands in it. -Individually purchased dedicated IP addresses -Preferably located in the North America region My plan would be to setup one Linux VPS as a gateway/firewall/VPN server and have all of my traffic routed through so that my other servers would not use of bandwidth by talking to each other. The trick is also finding a company that does Linux VPS AND MS SQL databases. Does anybody know of any hosting companies offer what I'm looking for? Let me know if I need to add more details.

• Redirecting traffic to a https site

  - by Saif

  In our mail server there are multiple virtual email domain hosted. User can use webmail.example.com (this is the first apache virtualhost) to check mail or they can use mail.THEIR-DOMAIN.com. If the put mail.THEIR-DOMAIN.com apache shows the webmail.example.com as it is the first virtualhost and mail.THEIR-DOMAIN.com doesn't exist. Recently we imposed https for webmail.example.com and added this mod_rewrite rule: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} But now users not getting the default webmail page as they were getting before. How can we redirect all request coming to the URL "mail.ANY-DOMAIN.com" to "https://webmail.example.com"? I've tried the following but it didn't work: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (mail.*) https://webmail.example.com Thanks for your help in advance.

• How is a nameserver chosen when DNS resolution occurs?

  - by Richard

  I have a few domains hosted on nameservers at Zerigo. Zerigo have 5 nameservers and I have all 5 in the nameserver records for my domains. The nameservers are in different geographical locations (3 in the US, one in London, and one in Amsterdam). When someone goes to a domain of mine and the DNS resolution occurs, how will it choose a nameserver? Will it always go to the nearest geographical one? Will it go to the one with fewest hops? Will it just choose one at random? (This is assuming all 5 are functioning perfectly). Thanks EDIT: And does it make any difference which order I list the nameservers in on the domain name records?

• How to access internal network covered by a squid proxy from internet?

  - by Forbidden Overseer

  Our campus uses a squid proxy caching server with a basic authentication for all outbound requests coming from internal network. The whole network uses private IP range from 172.16.0.0 to 172.31.255.255. Most of our faculty websites and library websites are hosted on LAN. I want to access those faculty websites and other internal websites when I am outside the proxy (say when I am at my home and not in campus). I don't know whether I can use the same basic authentication from outside to access those LAN websites. Is there a way I can do that? I don't know whether our proxy server allows it or not, but if that's possible - I want to know how (how to set up browser etc.)?

• Convert a string representation of a hex dump to a byte array using Java?

  - by ravigad

  I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array. I couldn't have phrased it better than the person that posted the same question here: http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21062554.html But to keep it original, I'll phrase it my own way: suppose I have a string "00A0BF" that I would like interpreted as the byte[] {0x00,0xA0,0xBf} what should I do? I am a Java novice and ended up using BigInteger and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple...

• Instant file sharing between users in PHP

  - by Skyfe

  Hi there, Working on a rather complex system in which users can directly exchange files with eachother from the website. However is any of these things possible: EITHER * Have another user download a file which is still being uploaded by another user ( in progress ) OR * Make a user automaticly ( instant ) download a file from another users PC through our website OR * Make a user automaticly (instant) download a file from our server ( so it's directly downloaded to the users pc and the progress shown on our website of the download progress, without the normal internet explorer dialog downloading the file or firefox ). Thank you very much in advanced, Best Regards, Webcodez.net. UPDATE: an example would be MSN's file sharing but then through a website instead of application.

• Using my ISerializable implementation instead of DataContractSerializer

  - by mpm

  My WCF client and server exchange objects whose types are defined on a class library shared by both, the server and the client. These objects implement custom serialization via ISerializable. However, my custom serialization is not being used. DataContractSerializer is being used, instead. How do I force my custom serialization to be used? The reason why I need to use my own serialization is because I do trasfer some big object graphs and my serialization algorithm does a good job in compressing/speeding up things.

• Don't panic - there is time!

  - by ripper234

  If you're thinking of moving to Shapado right this instance, take a breath. Yes, I think it's the right move in the long run (be it three months or a year). However, take into consideration that the platform is still not ready. It has bugs and feature-requests that should be fixed. Until they are, you are better off staying with Stack Exchange as long as you can. Of course, it is in your best interest to participate heavily in the 'meta discussion' that takes place at Shapado.com and vote on the features and bug fixes that you want.

• php codeigniter MySQL search query

  - by kalafun

  I want to create a search query on MySQL database that will consist of 5 different strings typed in from user. I want to query 5 different table columns with these strings. When I for example have input fields like: first name, last name, address, post number, city. How should I query the database that I dont always get all the rows. My query is something like this: SELECT user_id, username from users where a like %?% AND b like %?% AND c like %?% AND d like %?% AND e like %?%; When I exchange the AND for OR I always get all the results which makes sense, and when I use AND I get only the exact matches... Is there any function or statement that would help me with this?
