• ASP.NET Combo Box and List Box Performance Improvements - v2010 vol 1

  Check out this great new performance feature of our ASP.NET combo box and list box controls for the DXperience v2010.1 release. You can now manually populate lists with items based on the currently applied filter criteria. This means that you can significantly decrease web server workload by loading only a subset of all items when working with large datasets. For instance, when using a large data source, you can only request a few records to be visible on the screen. The rest of the items can...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  I am in China and have used freegate in the past -- http://en.wikipedia.org/wiki/Freegate Recently I've been having too many problems with that and some other web-based proxies I usually use. I have a website that is hosted in the US which I can access from China. Is there an easy way for me to setup my own secure private proxy? I'm sick of all my internet problems and looking for a new workable solution. Thank you! PS: and I really hope this is the right place for such a question...

• Windows 2008 Server can't connect to FTP

  - by stivlo

  I have Windows 2008 Server R2, and I am trying to install FTP services. My problem is I can't connect from outside, FileZilla complains with: Error: Connection timed out Error: Could not connect to server Here is what I did. With the Server Manager, I've installed the Roles FTP Server, FTP Service and FTP Extensibility. In Internet Information Services version 7.5, I've chosen Add FTP Site, enabled Basic Authentication, Allow a user to connect Read and Write. In FTP Firewall support on the main server, just after start page, I've set Data Channel Port Range to 49100-49250 and set the external IP Address as the one I see from outside. If I click on FTP IPv4 Address and Domain Restrictions, and click on Edit Feature Settings, I see that access for unspecified clients is set to Allow, so I click OK without changing those defaults. In FTP SSL Policy, I've set to Require SSL connection, certificate is self signed. I tried to connect with FileZilla from the same host and it works, however it doesn't work remotely, as I said above. I've enabled pfirewall.log, but apparently nothing gets logged. The server is in Amazon EC2, and on the security group inbound firewall rules, I've set that ports 21 and ports 49100-49250 accepts connections from everywhere. What else should I be checking to solve the problem?

• Portal View/Projection Matrix near plane

  - by melak47

  For RenderToTexture/Camera based portal rendering, the basics seems simple enough. However, with a free camera, most of the time it is going to be looking at such portals at an angle: Now a regular near clipping plane will not always work here, it will either intersect with the wall the portal is sitting on, or possibly with objects in front of the wall. The desired near clipping plane would be aligned like the portal, producing a view volume more like this: or this in 3D: So here is my question: How does one construct or "truncate" a view/projection matrix to achieve such an off-camera-normal (near) clipping plane?

• Shouldn't all source code be plain text? [on hold]

  - by user61852

  Some developing environment/languages save the source code you write in a binary/propietary format that you cannot see or edit with a generic text editor. I'm not talking about compiled code, but the source code. An example could be PowerBuilder and Oracle Forms. It's ok you use proprietary technology if you want, but not being able to open the source code you wrote, in a simple editor, if only to read it, seems like a very strict form of vendor lock-in. Also this prevents you from using text-based version controls that can show you the difference between two versions in a line-by-line base. If the code is plain text, you don't need a license in order to just open it, see it and learn from it. Should it be a golden rule to avoid vendor lock-in to avoid technologies that save your source code to anything but plain text files ?

• How to divide hex grid evenly among n players?

  - by manabreak

  I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

• Developer hardware autonomy in a managed desktop environment [closed]

  - by Troy Hunt

  I’m looking for some feedback on how developer PCs are managed within environments that have a strict managed desktop policy (normally large corporations). For example, many corporate environments control the installation of software and the deployment of patches and virus updates through a centralised channel. This usually means also dictating the OS version and architecture (32 bit versus 64 bit) which will likely also mean standardised hardware configurations. I’m particularly interested in feedback from developers who work in this sort of environment but have a high degree of autonomy over their machines. This might mean choosing your own hardware vendor, OS type and version and perhaps how the machines are built and maintained. I have several specific questions: How do you satisfy the needs of security, governance etc whilst maintaining your autonomy? For example, how do you address concerns about keeping virus definitions and OS patches up to date? Do you have a process for gaining exemption from standard desktop builds and if so, what do you need to demonstrate in order to get this? How have you justified this need to the decision makers? Essentially, what is the benefit to your role as a developer by having this degree of autonomy? Thanks very much everyone. Update: There's a great post from Jean-Paul Boodhoo which addresses the developer tool component of the quesiton here: http://blog.jpboodhoo.com/TheFallacyOfTheStandardizedDeveloperMachineimage.aspx

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• Best strategy for supporting multiple server communication from iPhone/android app?

  - by tipycalFlow

  I'm making an app that will be used in multiple hospitals in the US. As per HIPAA compliance requirement, every hospital will have its own server that complies with these requirements of ensuring patient data security, etc. Now the task is that the app should communicate with a particular server based on the login info. An additional requirement is that new hospitals(servers) are likely to be added along the way, even after the app is available on the market. So basically, according to some login credentials, the app should communicate with the server of the hospital assigned to that person. One pretty crude way is to set up our own server which links the hospitals with the login info and accordingly, provides a base-url for data exchange. Is there a more efficient way to handle this?

• Cisco configuration for public library internet

  - by AlternateZ

  I'm a C/C++ computer programmer turned IT support guy working for a public library. My day is usually spent helping random grandparents learn how to use email, so my networking knowledge is limited to what I can glean from google. Here's the situation. We have a public library with 20 PCs on a LAN and also public wifi access. Previously we were running all of this on 1 ADSL connection and people complained about low speeds. We hired a networking company to set up a Cisco dual-WAN router for us, and purchased an additional ADSL connection. The intention was to give the LAN PCs a guaranteed amount of bandwidth each, and then let the wifi users split the rest. The results were far worse than what we expected, and all we got from the company was excuses and they've since washed their hands of us. During busy periods, net performance on the LAN PCs are so poor that attaching files to gmail etc often times out and fails - far from the "guaranteed amount of bandwidth each" that we hope for! Sometimes it feels like performance is worse than before when we had 1 ADSL link and an unconfigured router? Anyways, surely this is a problem encountered a million times over across the world? (Sharing internet across many users effectively.) What are standard solutions for something like this? I admit to not even knowing the right jargon to google for (load balancing?) I'd appreciate any links to resources/guides that might help me get a better understanding of the problem/solutions, and perhaps some stories of your own experience in solving similar problems. This will help us evaluate and negotiate with network consultants in the future. If its relevant, our router config contains a section "policy-map" with "bandwidth percent" for each class of user (LAN, wifi), and "fair queue".

• What are ways to prevent files with the Right-to-Left Override Unicode character in their name (a malware spoofing method) from being written or read?

  - by galacticninja

  What are ways to avoid or prevent files with the RLO (Right-to-Left Override) Unicode character in their name (a malware method to spoof filenames) from being written or read in a Windows PC? More info on the RLO unicode character here: http://www.fileformat.info/info/unicode/char/202e/index.htm http://en.wikipedia.org/wiki/Bi-directional_text Info on the RLO unicode character when used by malware: http://www.ipa.jp/security/english/virus/press/201110/E_PR201110.html Mirror link: http://webcache.googleusercontent.com/search?q=cache:KasmfOvbVJ8J:www.ipa.jp/security/english/virus/press/201110/E_PR201110.html+&cd=1&hl=en&ct=clnk You can try this RLO character test webpage: http://www.fileformat.info/info/unicode/char/202e/browsertest.htm The RLO character is also already pasted in the 'Input Test' field in that webpage. Try typing there and notice that the characters you're typing are coming out in their reverse orders (right-to-left, instead of left-to-right). In filenames, the RLO character can be specifically positioned in the filename to spoof or masquerade as having a filename or file extension that is different than what it actually has. (Will still be hidden even if 'Hide extensions for known filetypes' is unchecked.) The only info I can find that has info on how to prevent files with the RLO character from being run is from the Information Technology Promotion Agency, Japan website: http://www.ipa.jp/security/english/virus/press/201110/E_PR201110.html (Mirror link). They adviced to use the Local Security Policy settings manager to block files with the RLO character in its name from being run. Can anyone recommend any other good solutions to prevent files with the RLO character in their names from being written or being read in the computer, or a way to alert the user if a file with the RLO character is detected? My OS is Windows 7, but I'll be looking for solutions for Windows XP, Vista and 7, or a solution that will work for all those OSes, to help people using those OSes too.

• Is it okay to have many Abstract classes in your application?

  - by JoseK

  We initially wanted to implement a Strategy pattern with varying implementations of the methods in a commmon interface. These will get picked up at runtime based on user inputs. As it's turned out, we're having Abstract classes implementing 3 - 5 common methods and only one method left for a varying implementation i.e. the Strategy. Update: By many abstract classes I mean there are 6 different high level functionalities i.e. 6 packages , and each has it's Interface + AbstractImpl + (series of Actual Impl). Is this a bad design in any way? Any negative views in terms of later extensibility - I'm preparing for a code/design review with seniors.

• Setting Up and Running Summary Advisor on an Exalytics Machine (Oracle-by-Example)

  - by Saresh

  If you are running Oracle BI on an Exalytics machine, you can use Summary Advisor to identify the aggregates that will increase query performance. Summary Advisor intelligently recommends an optimal list of aggregate tables based on query patterns that will achieve maximum query performance gain while meeting specific resource constraints. Summary Advisor then generates an aggregate creation script that can be run to create the recommended aggregate tables. Aggregate tables reduce query times by storing precomputed results for queries that include rolled-up data. This tutorial covers steps to set up, configure, and run Summary Advisor on an Exalytics machine using TimesTen database as a target for storing aggregates. You can find the Oracle By Example (OBE) in the Oracle Learning Library (OLL). The content in OLL is available to all customers, partners, and employees.

• RESOLVED Why does IPtables's NAT stop working when I enable the firewall's third interface?

  - by Kronick

  On my firewall I've three interfaces : eth0 : public IP (46.X.X.X.) eth0:0 public IP (46.X.X.Y.) eth1 : public IP (88.X.X.X.) eth2 : private LAN (172.X.X.X) I've setup a basic NAT which works great until I turn on the eth1 interface, I basically loose the connectivity. When I turn off the interface (ifconfig eth1 down) then the NAT re-work. I've added some policy routing via iproute, which makes my three public IP's available. I don't understand why turning on eth1 on makes the LAN unavailable. PS : weirder ; when I turn on eth1 BUT remove the NAT, then the firewall is accessible by using the public IPS. So to me it's exclusively a NAT issue, since without the NAT the network works while with the NAT without the second public interface, the NAT does work. Regards EDIT : I've been able to make it work by using iproute2 rules. That was definitely a routing issue. Here is what I did : ip rule add prio 50 table main ip rule add prio 201 from ip1/netmask table 201 ip rule add prio 202 from ip2/netmask table 202 ip route add default via gateway1 dev interface1 src ip1 proto static table 201 ip route append prohibit default table 201 metric 1 proto static ip route add default via gateway2 dev interface2 src ip2 proto static table 202 ip route append prohibit default table 202 metric 1 proto static # mutipath ip rule add prio 221 table 221 ip route add default table 221 proto static \ nexthop via gateway1 dev interface1 weight 2\ nexthop via gateway2 dev interface2 weight 3

• git changing head not reflected on co-dev's branch

  - by stevekrzysiak

  Basically, we undid history. I know this is bad, and I am already committed to avoiding this at all costs in the future, but what is done is done. Anyway, I issued a git push origin <1_week_old_sha:master to undo some bad commits. I then deleted a buggered branch called release(which had also received some bad commits) from remote and then branched a new release off master. I pushed this to remote. So basically, remote master & release are clones and just how I want them. The issue is if I clone the repo anew(or work in my current repo) everything looks great....but when my co-devs delete their release branch and create a new one based off the new remote release I created, they still see all the old junk I tried to remove. I feel this has to do with some local .git files mistaking the new branch release for the old release. Any thoughts? Thanks.

• How can I choose between Linux and Windows hosting? [closed]

  - by Mohamad

  Possible Duplicate: How to find web hosting that meets my requirements? I am a relative beginner when it comes to choosing web servers and hosting plans. I'm about to signup for a hosting plan with GoDaddy. My main requirement is ColdFusion and MySQL. The plans on offer include Linux and Windows based plans. Which one should I choose, and why? I don't have a lot of requirements other than what I mentioned above. I never used Linux before but I doubt I'll ever need to do anything beyond tampering with my account. What are the main advantages of one over the other?

  The acquisition battle has come and gone, and it’s HP that’s become Palm’s new owner. In general this news has been greeted withgladcries,despite (or maybe because) it was so unexpected. In general everybody assumes that the marriage of Palm software and HP hardware will be a good one, and that HP will also release a webOS-based tablet device.However, there’s an interesting dissenting opinion on VisionMobile (a blog I highly recommend, by the way).

• External classes positions don't work?

  - by SystemNetworks

  I have an external class which reads the user's mouse clicks. I gave a position where the user have to click, and when the user clicks on that position, it would turn my boolean "mouse" to true. But when I connect that to my game(state based) class, it does not work. Here's the code: External class public void UI(Input input, GameContainer gc, float posX, float posY) { int x = Mouse.getX(); int y = Mouse.getY(); if(posX<=100 && posY<=100) { if(Mouse.isButtonDown(1)) { mouse = true; } } } Game class(main) public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException { int x = Mouse.getX(); int y = Mouse.getY(); civ.UI(input, gc, x,y); } The problem is when I click my mouse at posX<=100 && posY<=100. It does not work.

• Twitter Customer Sentiment Analysis

  - by Liam McLennan

  The breakable toy that I am currently working on is a twitter customer sentiment analyser. It scrapes twitter for tweets relating to a particular organisation, applies a machine learning algorithm to determine if the content of tweet is positive or negative, and generates reports of the sentiment data over time, correlated to dates, events and news feeds. I’m having lots of fun building this, but I would also like to learn if there is a market for quantified sentiment data. So that I can start to show people what I have in mind I have created a mockup of the simplest and most important report. It shows customer sentiment over time, with important events highlighted. As the user moves their mouse to the right (forward in time) the source data area scrolls up to display the tweets from that time. The tweets are colour coded based on sentiment rating. After I started working on this project I discovered that a team of students have already built something similar. It is a lot of fun to enter your employers name and see what it says.
