• How to setup users for desktop app with SQL Azure as backend?

  - by Manuel

  I'm considering SQL Azure as DB for a new application I'm developing. The reason I want to go with Azure is because I don't want to have to maintain yet another database(s) and I want my users to be able to access the data from anywhere. The problem is that I'm not clear regarding how to users will connect. The application is a basic CRUD type of windows app. I've read that you need to add your IP to SQL Azure's firewall to connect to it, but I don't know if it's only for administration purposes only. Can anyone clarify if anyone (anywhere) can access the data with the proper credentials? Which of the following scenarios would work best (if at all)? A) Add each user to SQL Azure and have the app connect directly to Azure as if it was connecting to SQL Server B) Add an anonymous user SQL Azure and pass the real user's password/hash with every call so the Azure database can service the requests accordingly. C) Put a WCF service in between so that it handles the authentication stuff. The service will only serve the appropriate information to the user given his/her authentication and SQL Azure would be open to the service exclusively. D) - ideas are welcomed - This is confusing because all Azure examples I see are for websites. I have a hard time believing SQL Azure wouldn't handle the case of desktop apps connecting to it. So what's the best practice?

• How do I move my LVM 250 GB root partition to a new 120GB hard disk?

  - by Dennis Schma

  I have the following situation: My current Ubuntu installation is running from an external HDD (250 GB) because I was to lazy to buy an new internal hdd. Now i've got a new internal (120GB) and i want to move everything to the internal. Installing Ubuntu new is out of disscussion because its to peronalized. Luckily (i hope so) the root partition is partitioned with LVM, so i hope i can move the partition to the smaller internal HDD. Is this possible? And where do i find help?

• Which hard disk drive is which?

  - by djeikyb

  I want to know which hard disk drive corresponds to which device path. It's trivial to match the hard disk stats (brand, size) with the dev path, but I want more. I want to know which drive is which inside my case. What's a good way to go about getting this info? Rules: I am a lazy bum. I don't want to tear apart my server to remove all the drives, then add back one by one. A reboot is acceptable. The drives are inconveniently scrunched together in the case. All label information is hidden. The case can be opened. Most disks are SATA, so theoretically hot swappable. Unplugging cables is fair game. Bonus: For a cli only solution. I'll award answer to the best/easiest gui or cli answer, and give a bounty to the next-best answer of the other kind. Or maybe the other way around, because the bounty is worth more points.

• Nginx load distribution and multi-domain SSL

  - by Steve Clark

  I'm researching into the best methods of two new parts of our infrastructure, hopefully finding a single solution for both. 1) We're currently running a single application server, and we're going to be adding an additional application server and load balance between the two. 2) We handle a few thousand domains across the application server(s), and we're looking to support SSL. The best method i've come across so far is using nginx for it's Load Distribution to serve the requests to the application servers, and for it's SSL support. If a request is using SSL, nginx accepts the request on, terminates SSL and pipes to apache (app servers). Now, that's all good, but i'm yet to figure out how we can let nginx handle multiple domains using SSL. We're potentially looking at using UCC SSL Certs, so we can support 150 domains on a single certificate, with each cert on a single IP. I'm all new to this (My experience is just with physical load balancers and a single domains on SSL), so any advice would be very much appreciated.

• Is sending data to a server via a script tag an outdated paradigm?

  - by KingOfHypocrites

  I inherited some old javascript code for a website tracker that submits data to the server using a script url: var src = "http://domain.zzz/log/method?value1=x&value2=x" var e = document.createElement('script'); e.src = src; I guess the idea was that cross domain requests didn't haven't to be enabled perhaps. Also it was written back in 2005. I'm not sure how well XmlHttpRequests were supported at the time. Anyone could stick this on their website and send data to our server for logging and it ideally would work in most any browser with javascript. The main limitation is all the server can do is send back javascript code and each request has to wait for a response from the server (in the form of a generic acknowledgement javascript method call) to know it was received, then it sends the next. I can't find anyone doing this online or any metrics as to whether this faster or more secure than XmlHttpRequests. I don't know if this is just an old way of doing things or it's still the best way to send data to the server when you are mostly trying to send data one way and you need the best performance possible. So in summary is sending data via a script tag an outdated paradigm? Should I abandon in favor of using XmlHttpRequsts?

• Should I keep separate client codebases and databases for a software-as-a-service application?

  - by John

  My question is about the architecture of my application. I have a Rails application where companies can administrate all things related to their clients. Companies would buy a subscription and their users can access the application online. Hopefully I will get multiple companies subscribing to my application/service. What should I do with my code and database? Seperate app code base and database per company One app code base but seperate database per company One app code base and one database The decision involves security (e.g. a user from company X should not see any data from company Y) performance (let's suppose it becomes successful, it should have a good performance) and scalability (again, if successful, it should have a good performance but also easy for me to handle all the companies, code changes, etc). For the sake of maintainability, I tend to opt for the one code base, but for the database I really don't know. What do you think is the best option?

• Can I launch Windows 8 with grub?

  - by Laurbert515

  I accidentally deleted the boot loader for Windows 8 (I think). Here is the situation: I just got a new computer with 2 HDD (sda, sdb). Now, all of the windows OS was installed on sdb (all except for about 210 MB on sda). I formatted sda and installed Kubuntu 12.04.2 (which only loads the terminal because it says it can't find a screen, but that's another story!) Now, my Windows 8 data and NTFS partitions, etc. are still on sdb and untouched. Unfortunately, I cannot see an option to boot into Windows 8 in grub, so is there a way that I can go about using grub to point to the Windows 8 OS? The only other option I can think of is to buy a fresh copy of Windows 8 and install it fresh (no, I didn't create a backup USB because I'm an idiot ...)

• The better way to ask for input?

  - by Skippy

  I am wondering which is the best way to go with java code. I need to create a class with simple prompts for input.. I have tried using both classes and cannot work out the particular benefits for each. Is this because I am still in the early stages of programming or are there situations that will occur as it becomes more complex?? import java.util.Scanner; public class myClass { Scanner stdin = new Scanner(System.in); public String getInput(String prompt) { System.out.print(prompt); return stdin.nextLine(); } ... or import java.io.*; public class myClass { public static void main(String[] args) throws IOException { BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in)); System.out.print("Input something: "); String name = stdin.readLine(); I know these examples are showing different methods within these classes, but thought this might serve well for the discussion. I'm really not sure which site is the best to ask this on.

• Is full partition encryption the only sure way to make Ubuntu safe from external access?

  - by fred.bear

  (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

• What are the Search engine affects of registering the same domain on multiple top level domains (ie. .com, .ie, .nl etc.)?

  - by user1020317

  I'm looking to register a few more domains for my company, I have my-company.com at the moment, but now require my-company.com.au and my-company.nl and some others.. I'm running through my options and wondering what is the best.. Duplicate all the content on the .com package and make a replica at the other domains Buy the other domains but do a 301 redirect back to the .com domain. Create a full new website with different content for the new domains, thus having no text duplication We currently sell over the world so would like to raise our Search rankings in various countries, can this be done by buying the domain in the country, and if so, how will the above methods affect our search rankings. Any other suggestions are welcome!

• Really, Mobile Devices will Take Over the World?

  - by p.gielens

  My blog has been quiet for quite a while. My inspiration comes from crunching/exchanging information which I should do more often. Gartner analysis tells us that by 2013 mobile phones will overtake PC’s as the most common Web access device worldwide. A few years back I would have said non sense, but apparently most Web users are comfortable with less processing power. Just take a look at the increasing business in Netbooks. Wouldn’t it be great to have a mobile phone which can connect wirelessly to my home TV, monitor, car display, mouse, keyboard, etc? And to have the processing power of the current Netbook generation? Where can I buy it? Why are we making our PC devices (for instance the slate) smaller while we can make our mobile device’s functionality bigger? What about the single responsibility principle? Does it apply to physical devices as well as good object-oriented software?

• It Ain't Over 'Til It's Over

  - by Oracle OpenWorld Blog Team

  Oracle OpenWorld 2012 is behind us. Well, for San Francisco, anyhow. The team is already working on the Latin America event which takes place in December in Sao Paulo, and an OpenWorld in Asia for 2013 as well. And of course they're already working on the next San Francisco OpenWorld for 2013. So what happens after the conference is over? People pack up demo and network gear and ship it out to wherever it's going next; take down and recycle signage; strike the keynote set, the exhibition and demo halls, the street tents, and anything else that was constructed just for the conference. There's a lot of post-conference analyis going on too. Oracle and partner marketing teams are looking at and following up on the leads they got from booth, demo, and lounge traffic. The events team is evaluating the session and conference surveys you filled out if you attended -- looking to identify the best speakers, what worked and didn't work, how you liked the venues, the food, the entertainment, the presentations. From all of that information will come recommendations for next year on what to keep doing, what to do better, and what not to do at all. The goal for each year's conference is to be better than last year's. If you attended and haven't filled out the surveys yet, you have until October 19 for them to be counted, and for you to be entered into a daily sweepstakes. Click here for more information. Posts to this blog will slow down for a while, but we'll post news about Oracle OpenWorld in San Francisco and around the world when we have it. Any suggestions about future blog topics are welcome. Oh - I forgot to mention that you can sign up to be notified when registration for Oracle OpenWorld 2013 goes live. If you register at that time you'll get the best discount available on attending next year. So sign up, and stay tuned.

• Creating User Generated Subdomains

  - by nicks451

  Hi there, The company I work for is close to being finished with our first web app and we recently made the decision to offer hosting for our smaller customers. (We provide software to lending companies and our larger customers are required to buy redundant servers to host their application). What we are trying to work out right now is how to create user generated subdomains that will hold a new instance of the software. So a user will be able to sign up and say that the company name is XYZ Credit once they click on the create account button a url of xyzcredit.ourcompanyname.com is created and the user is redirected to it. The servers that we want to use are running CentOS 5.5 and Virtualmin 3.83. Thank you for your help, Nick

• Why do the Nouveau drivers work better than the Nvidia ones?

  - by user50774

  I have a bit of a weirdie here. My rig uses an Nvidia GeForce 8600 GTS in a PCIE x16 slot. Up to about a year ago, no problems with the card. I then started getting random crashes. They got more frequent. Now, first thought: It's an old card. But I don't have the bucks to buy a new one, and my mobo doesn't have the DVI input that my monitor needs. So, I decided to take a shot with the Nouveau drives. Amazingly, they have worked flawlessly. Does anyone have a guess as to why?

• Applying for job: how to showcase work done for (private) past clients?

  - by user33445566

  I want to apply for my first "real" (read: non-freelance) Ruby on Rails job. I've built several apps already. My best work (also the most logically complicated app) was for a freelance client, and I'd like to show it to potential employers. Only problem is: it isn't online anymore. And I've lost touch with the client. How can I include this work in my portfolio? About the app: It's a Facebook game. The client's business idea for this app was not the best. It was never going to make any money. I think it was kind of a vanity side project for him. The logo and graphics are nice-looking, though, and were designed by the client. I've actually spent a lot of time recently recoding most of the app, and adding a full test suite. I want to showcase the BDD / TDD skills I've acquired. I'm not very familiar with the etiquette (/law?) concerning this situation. Can I just put my new version of the app up at a free Heroku URL (perhaps with a "credits" section, where I credit the ideas and graphic designs to my former client)? NOTE: Again, this is just to show potential employers. I am not trying to market the app as my idea, or attract any users. Can I put some or all of the code on GitHub? What if I don't put the code up publicly, but merely send a tarball to potential employers? Do I need to ask permission from my former client (and what if he says no)? The last thing I want to do is get in any legal trouble, or offend people I'm trying get a job from. But I believe that my work and experience on this app are my highest recommendation for getting a job.

• What are the dis-advantages of installing the ssl certificate for the naked domain?

  - by user1744649

  I might buy an SSL certificate for my sie. I know that it will help me in many ways. But will there be dis-advantages also? eg. If I load an image from another server (using plain http), will that alert the customer saying something is wrong? Will I be able to use all existing codes like phpbb, awstats etc without a problem? Will there be any issue if redirect a page from my domain.com to my subdomain.domain.com using a meta refresh or .htaccess? Will there be any issue if redirect a page from my subdomain.domain.com to my domain.com using a meta refresh or .htaccess? Any other issue that I might get into? Thanks.

• YouSendIt Alternative?

  - by user4855

  Looking for a reasonably priced alternative to YouSendIt's exorbitant pricing for an embedded, unbranded (i.e. no "Uploads by SomeCompany" or at the very least, discrete, subtle co-branding) file upload solution for my client's print shop Website. To do what we want to do with YouSendIt, we're looking at a corporate account of $995 USD plus $29.99 USD monthly fee, that is only sold pro-rated, so you have to buy the entire year's worth. To me, this is just unacceptable considering the commodity pricing of storage and bandwidth nowadays. For data, we're looking at roughly 10MB per upload, with perhaps 250-1000 uploads per month, with transient data storage of no more than 30 days (and more than likely 1-2 business days) for a total of 10 GB transfer (upload) and 10 GB transfer (download, to the print shop) at the very max each month. Any ideas? Everything I've found through searching seems to be geared more towards personal file sharing and not for embedding into Websites. Thanks

  I have an older laptop with a ADA hard disk I can't really buy a new one so I want to erase Windows Vista on my computer and only have Ubuntu so that I can have more space. How do I make it go directly to my blank CD? My Windows Vista is messed up and I can't even get into it. I want to download the new version of Ubuntu while in Ubuntu. I downloaded it but it didn't go directly to the blank CD. I tried to copy all of Ubuntu onto the CD once it was downloaded but it says there was an error while copying. What should I do?

• Git Repo to mantain the app configurations in several servers

  - by user62904

  Hi! I need to versioning in a GIT repository, configurations of a particular platform, spread across multiple servers. Take into account that in each of these servers there are completely different configurations, while the application is the same. What is the best way to do this? Create a branch for each server repository.git:conf -- [branch Server 1] repository.git:conf -- [branch Server 2] repository.git:conf -- [branch Server N] Note: This method seems to me, that is difficult to maintain because each change in the server configurations, I need to create subbranches which becomes confusing. Create a single repo with a different directory for each server repository.git:conf/Server 1 repository.git:conf/Server 2 repository.git:conf/Server N Note: This is easy to mantain Create a repo for each server repository_1.git:conf repository_2.git:conf repository_N.git:conf Note: This method requires me to create a branch for each new server. There are other methods, what are the best practices in this case? Should I use the one that I feel most comfortable? Tks, Gulden PT

• How do I know if my disks are being hit with too much IO reads or writes or both?

  - by Mark F

  Hi All, So I know a bit about disk I/O and bottlenecks relating to this especially when relating to databases. But how do I really know what the max IO numbers will be for my disks? What metric might be available to me for working out roughly (but needs to be a good approximation) of how much capacity (if you will) have I got left available in I/O. I've seen it before where things are bubbling along nicely and then all of a sudden, everything screams to a halt, and it ends up being an IO bound problem. Is there a better way to predict when IO is reaching its limits? This article was interesting but not giving the answer I desire. "http://serverfault.com/questions/61510/linux-how-can-i-see-whats-waiting-for-disk-io". So is my best bet surrounding just looking at 'CPU IO WAIT'? There must be a more reactive method for this? Best, M
