• Mistaken dist-upgrade, is this bad?

  - by SpashHit

  I was looking for Update Manager on Ubuntu 10.10 Netbook Edition and couldn't find it, so in Terminal I did: sudo apt-get update sudo apt-get upgrade I got a message saying some packages were "held back" and searching online gave me the suggestion to do: sudo apt-get dist-upgrade So I did that and it updated my kernel and now uname -a says I have 2.6.35-23-generic #40-Ubuntu SMP. My system is still working normally, but I'm now second-guessing if I did the right thing. Was this kernel update meant for the next version of Ubuntu? Should I try to back it out?

• Displaying Tweets in an ASP.NET UserControl with TweetSharp

  As I mentioned in my previous blog post, I'll be having a little fun over the next few weeks talking about all of the Social Media APIs I've been experimenting with. I thought I would start out today by talking about one of the most popular services, Twitter. Twitter is essentially a microblogging service that allows its users to post messages of up to 140 characters long known as Tweets. Users can subscribe to each other and see tweets from all of their subscriptions in their main feed listings. Due to this ease of providing and receiving updates to and from the masses, Twitter has been adopted by anything from bloggers to celebrities to large corporations. If you have a blog or just a website in general, having a Twitter account alongside it could potentially be a useful way to attract new visitors. Displaying your tweets on your website and ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• HSSFS Part 3: SQL Saturday is Awesome! And DEFAULT_DOMAIN(), and how I found it

  - by Most Valuable Yak (Rob Volk)

  Just a quick post I should've done yesterday but I was recovering from SQL Saturday #48 in Columbia, SC, where I went to some really excellent sessions by some very smart experts.  If you have not yet attended a SQL Saturday, or its been more than 1 month since you last did, SIGN UP NOW! While searching the OBJECT_DEFINITION() of SQL Server system procedures I stumbled across the DEFAULT_DOMAIN() function in xp_grantlogin and xp_revokelogin.  I couldn't find any information on it in Books Online, and it's a very simple, self-explanatory function, but it could be useful if you work in a multi-domain environment.  It's also the kind of neat thing you can find by using this query: SELECT OBJECT_SCHEMA_NAME([object_id]) object_schema, name FROM sys.all_objects WHERE OBJECT_DEFINITION([object_id]) LIKE '%()%'  ORDER BY 1,2 I'll post some elaborations and enhancements to this query in a later post, but it will get you started exploring the functional SQL Server sea. UPDATE: I goofed earlier and said SQL Saturday #46 was in Columbia. It's actually SQL Saturday #48, and SQL Saturday #46 was in Raleigh, NC.

• Can we set up svn server on a local computer without any network access?

  - by Aitezaz Abdullah

  I want to set up an SVN repository on my computer without any network access. I am working on a code without any collaborator, so I don't want it to be publicly available. I read the following post. http://stackoverflow.com/questions/6001445/local-source-control-repository-cross-platform but this post suggests using online svn repository services that give free repositories. In that case, my code will be publicly available (as is included in the terms of free plans). So I was wondering if I can set up a local server on my windows xp machine that only I access even when I don't have any internet connection?

• Licensing approach for .NET library that might be used desktop / web-service / cloud environment

  - by Bobrovsky

  I am looking for advice how to architect licensing for a .NET library. I am not asking for tool/service recommendations or something like that. My library can be used in a regular desktop application, in an ASP.NET solution. And now Azure services come into play. Currently, for desktop applications the library checks if the application and company names from the version history are the same as the names the key was generated for. In other cases the library compares hardware IDs. Now there are problems: an Azure-enabled web-application can be run on different hardware each time (AFAIK) sometimes the hardware ID for the same hardware changes unexpectedly checking the hardware ID or version info might not be allowed in some circumstances (shared hosting for example) So, I am thinking about what approach I can take to architect a licensing scheme that: is friendly to customers (I do not try to fight piracy, but I do want to warn the customer if he uses the library on more servers than he paid for) can be used when there is no internet connection can be used on shared hosting What would you recommend?

• Is there an 'off the shelf' platform for making a new website similar to Elance?

  - by user17747

  I am interested in developing a website that is similar to 'elance' but for a particular vertical. Is there an 'off the shelf' platform you can recommend for getting started with this, or would I need to develop this web service from scratch? When I write 'platform' I am referring to things such as 'shopify' for e-commerce sites, or 'ning' for social websites. I want to create a multi-merchant professional services site. The site would need to support functionality such as: allowing merchants to open and manage their own profile. merchants would accept payments from customers through the site. file transfers between merchants and customers. merchant ratings by customers.

• Redirect from https://mydomain.com to http://mydomain.com

  - by Charlie

  Many of my visitors have bookmarked my site already wtih https://mydomain.com. Under the bad advice of a programmer, I put my whole Joomla site under ssl. I do not sell anything or provide any member services. I asked him many times if it would slow my site down - he said it wouldn't. I knew it did, I've researched on this site and realized it does slow the site down because of no cache of the pages. Understood. Please, someone tell me how to get away from it now. I'm not sure how to approach this, should I add something to my htaccess or my main index.php file? I've looked all over the net, there is much advice for adding redirectives for going from http to https, but very few answers regarding the opposite of going from https to http. Thank you very much for your time. I appreciate it.

• How can I monitor a website for malicious changes to the files

  - by rossmcm

  I had an occasion recently where our website was compromised - a link farm was added to a couple of the pages on one occasion, and on another occasion, a large and nasty aspx file was put on the server. I won't mention the host's name (Hostway), but I was pretty annoyed that someone was able to do this. No, it wasn't a leaky password - around 10 sites hosted by HW with consecutive IP addresses got trashed. Anyway. What I need is a utility or service (preferably free) that takes a snapshot of my websites contents, and then regularly monitors the files (size and datestamp) for unauthorized changes or additions, and alerts me. I've used web services that monitor one file for changes, but I'm looking for something a bit more aggressive.

• Exposing warnings\errors from data objects (that are also list returned)

  - by Oren Schwartz

  I'm exposing Data objects via service oriented assembly (which on future usages might become a WCF service). The data object is tree designed, as well as formed from allot of properties.Moreover, some services return one objects, others retrieve a list of them (thus disables throwing exceptions). I now want to expose data flow warnings and wondering what's the best way to do it having to things to consider: (1) seperation (2) ease of access. On the one hand, i want the UI team to be able to access a fields warnings (or errors) without having them mapping the field names to an external source but on the other hand, i don't want the warnings "hanged" on the object itself (as i don't see it a correct design). I tought of creating a new type of wrapper for each field, that'll expose events and they'll have to register the one's they care about (but totally not sure) I'll be happy to hear your thoughts. Could you please direct me to a respectful design pattern ? what dp will do best here ? Thank you very much!

• Coordinating team code review sessions

  - by Wade Tandy

  My question has two parts: 1) In your team or organization, do you ever do in-person code reviews with all or part of a team, as opposed to online reviews using some sort of tool? 2) How do you structure these meetings? Do you choose to focus on one person's code in a given meeting? Do you look at everything? Take a random sample? Ask people on the team what they'd like to have looked at of theirs? I'd love to add this practice to my development team, so I'd like to hear how others are doing it.

• Learning about security and finding exploits

  - by Jayraj

  First things first: I have absolutely no interest in learning how to crack systems for personal enrichment, hurting other people or doing anything remotely malicious. I understand the basis of many exploits (XSS, SQL injection, use after free etc.), though I've never performed any myself. I even have some idea about how to guard web applications from common exploits (like the aforementioned XSS and SQL injection) Reading this question about the Internet Explorer zero-day vulnerability from the Security SE piqued my curiosity and made me wonder: how did someone even find out about this exploit? What tools did they use? How did they know what to look for? I'm wary about visiting hacker dens online for fear of getting my own system infected (the Defcon stories make me paranoid). So what's a good, safe place to start learning?

• Installing Ubuntu on a Windows CE 6.0 EzBook PC (ez-72a)

  - by nmacholl

  I recently inherited a cheap EzBook PC and decided it might be fun to throw Ubuntu on it. I have a USB all setup but for the life of me can't get it to boot from USB! I've looked online and can't seem to find the motherboard details anywhere to access the BIOS and more applications won't work on Windows CE so I'm stuck. Is there an obscure Windows CE installer out there? It's really frustrating when I can't get to the BIOS - and I don't have a manual. If anyone knows anything I'd appreciate it!

• File manager respawns with ubuntuone

  Starting Feb 11, my Ubuntu 10.10 desktop respawns FileManager many times(hundreds). You can observe the "Starting File Manager" processes at the bottom of the gnome desktop.

• Is there any text editor for windows which can save files with code highlight for viewing

  - by user1713836

  I want some software for Windows where I can save code snippets and other daily usable commands in one file. Everyday I find some small code snippets which I want to save in a single file. Just like we have code snippet savers online, I want something offline on Windows, basically with all the features Microsoft Word has, but with code highlight. It should be lightweight like Notepad++. I mean if I select the code and then press some button, it should change the color according to the language. Currently I use Notepad++, but in it, I can't select small code snippets on one page. It either highlights the entire file or nothing.

• How to Access Your Router If You Forget the Password

  Routers protect their web interfaces, where you can configure their networking, parental control, and port forwarding settings, with a username and password. These default passwords can be changed to protect the router’s settings. If you’ve forgotten a router’s password – or if you acquired a used router and don’t know its password – there’s a way to reset the password. You may also be able to forward ports without knowing the password.

• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  - by jraulvc

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• implementing match-making & community system for multiplayer games

  - by kamziro

  These days, games often have multiplayer portals with chat channels & match making system for the multiplayer aspects of the game. An example would be battle.net, magic the gathering online's chat rooms, halo etc. Now, for the rest of us indie gamers that probably won't be able to spend much development effort on creating those back-ends from scratch, what options do we have? I was thinking of something along the line of using IRC as the backbone of the system. From there, the "community" aspect and implement player tracking, game tracking and match making on top of that. It seems to be what the old battle.net (brood war era) used to be. The question is, is this easy to do? What does it take to run an irc server, and I suppose this also requires writing an IRC client (which seems to have been done a lot these days?)? If there are other ways as well (say, an open framework for this stuff), let's hear them too.
