  • How to Enable User-Specific Wireless Networks in Windows 7

    - by The Geek
    Wireless network settings in Windows 7 are global across all users, but there’s a little-known option that lets you switch them to per-user, so each user has access to only the networks they are allowed to connect to. Here’s how it all works. How is this useful? Maybe you want to prevent a particular user from accessing the internet—if you don’t give them the wireless password, they won’t be able to get online. This could be very useful if you’ve got mini-people playing games on the family PC, but you don’t want them getting online Latest Features How-To Geek ETC How to Enable User-Specific Wireless Networks in Windows 7 How to Use Google Chrome as Your Default PDF Reader (the Easy Way) How To Remove People and Objects From Photographs In Photoshop Ask How-To Geek: How Can I Monitor My Bandwidth Usage?

  • Mobile App Notifications in the Enterprise Space: UX Considerations

    - by ultan o'broin
    Here is a really super website of UX patterns for Android: Android Patterns. I was particularly interested in the event-driven notification patterns (aka status bar notifications to developers). Android - unlike iOS (i.e., the iPhone) - offers a superior centralized notifications system for users.   (Figure copyright Android Patterns)   Research in the enterprise applications space shows how users on-the-go, prefer this approach, as: Users can manage their notification alerts centrally, across all media, apps and for device activity, and decide the order in which to deal with them, and when. Notifications, unlike messages in a dialog or information message in the UI, do not block a task flow (and we need to keep task completion to under three minutes). See the Anti-Patterns slideshare presentation on this blocking point too. These notifications must never interrupt a task flow by launching an activity from the background. Instead, the user can launch an activity from the notification. What users do need is the ability to filter this centralized approach, and to personalize the experience of which notifications are added, what the reminder is, ability to turn off, and so on. A related point concerning notifications is when used to provide users with a record of actions then you can lighten up on lengthy confirmation messages that pop up (toasts in the Android world) used when transactions or actions are sent for processing or into a workflow. Pretty much all the confirmation needs to say is the action is successful along with key data such as dollar amount, customer name, or whatever. I am a user of Android (Nexus S), BlackBerry (Curve), and iOS devices (iPhone 3GS and 4). In my opinion, the best notifications user experience for the enterprise user is offered by Android. Blackberry is good, but not as polished and way clunkier than Android’s. What you get on the iPhone, out of the box, is useless in the enterprise.

  • How does a game developer get feedback from gamers (not developers) or start a forum community without paying for advertising or hiring Q&A teams?

    - by Carter81
    I am familiar with a lot of game developer forums, but I'd assume this is much less likely to attract more casual commentators. I also fear that feedback from a gamer's perspective would often be tainted by their game dev perspective. For example, if I were making a RTS game and wanted to get feedback from "The RTS gamers" where would I go? Is there a general idea of what type of website or forum to go to? Do you go to specific game websites, to try to "steal" attention? Would this not equate to spam or inappropriate posting? What is considered appropriate and inappropriate? I am not asking for specifics. I am asking how one "starts a community", or how one "gets feedback from gamers" without resorting to spamming forums or 'advertising' just to see what sticks. What TYPE OF PLACE does one go? Are there already sites designed for this purpose? I tried going to what was once a very popular forum for feedback from what I believed was a niche hardcore group of gamers in the genre, but its popularity seemed to have died significantly; Leaving only trolls and very young teenagers. The resulting feedback was quite disappointing, mainly for how little feedback it resulted. Many years ago, feedback would flood in by the hundreds so quickly. Without this website, I am at a loss as to where to go to see what people think of ideas, gather feedback from a gamer's perspective (not a developer's perspective), or where to pull from to start my own site's forum. I am out of ideas of what to do, short of going to various game forums to post in the off-topic sections there.

  • CyanogenMod Updates; Rolls out Android 2.3 to the Less Fortunate

    - by ETC
    If you’re one of the less fortunate (namely those forgotten by their carrier when it comes to phone OS upgrade time) you’ve got a friend in Cyanogen. They’ve rolled out a new Release Candidate update that includes Android 2.3 and a host of performance tweaks. First thing to note is that this is an RC and if you upgrade from CyanogenMod 6 to CyanogenMod 7 RC you’ll be trading a little bit of stability and a few features that haven’t made the jump from 6 to 7 in return for the newest features of Android 2.3. If you’re not comfortable with that wait for CyanogenMod 7 to update to a final release. For the intrepid, hit up the link below to read more and grab a copy. CyanogenMod-7 Release Candidates!

  • How to manage long running background threads and report progress with DDD

    - by Mr Happy
    Title says most of it. I have found surprising little information about this. I have a long running operation of which the user wants to see the progress (as in, item x of y processed). I also need to be able to pause and stop the operation. (Stopping doesn't rollback the items already processed.) The thing is, it's not that each item takes a long time to get processed, it's that that there are usually a lot of items. And what I've read about so far is that it's somewhat of an anti-pattern to put something like a queue in the DB. I currently don't have any messaging system in place, and I've never worked with one either. Another thing I read somewhere is that progress reporting is something that belongs in the application layer, but it didn't go into the details. So having said all this, what I have in mind is the following. User request with list of items enters the application layer. Application layer gets some information from the domain needed to process the items. Application layer passes the items and the information off to some domain service (should the implementation of this service belong in the infrastructure layer?) This service spins up a worker thread with callbacks for both progress reporting and pausing/stopping it. This worker thread will process each item in it's own UoW. This means the domain information from earlier needs to be stored in some DTO. Since nothing is really persisted, the service should be singleton and thread safe Whenever a user requests a progress report or wants to pause/stop the operation, the application layer will ask the service. Would this be a correct solution? Or am I at least on the right track with this? Especially the singleton and thread safe part makes the whole thing feel icky.

  • Trigger IP ban based on request of given file?

    - by Mike Atlas
    I run a website where "x.php" was known to have vulnerabilities. The vulnerability has been fixed and I don't have "x.php" on my site anymore. As such with major public vulnerabilities, it seems script kiddies around are running tools that hitting my site looking for "x.php" in the entire structure of the site - constantly, 24/7. This is wasted bandwidth, traffic and load that I don't really need. Is there a way to trigger a time-based (or permanent) ban to an IP address that tries to access "x.php" anywhere on my site? Perhaps I need a custom 404 PHP page that captures the fact that the request was for "x.php" and then that triggers the ban? How can I do that? Thanks! EDIT: I should add that part of hardening my site, I've started using ZBBlock: This php security script is designed to detect certain behaviors detrimental to websites, or known bad addresses attempting to access your site. It then will send the bad robot (usually) or hacker an authentic 403 FORBIDDEN page with a description of what the problem was. If the attacker persists, then they will be served up a permanently reccurring 503 OVERLOAD message with a 24 hour timeout. But ZBBlock doesn't do quite exactly what I want to do, it does help with other spam/script/hack blocking.

  • UPDATE FOR BI PUBLISHER ENTERPRISE 10.1.3.4.2 NOVEMBER 2011

    - by Tim Dexter
    It's Friday, that means its patch release time. Why do we do this to ourselves, 'we'll release on Friday!' It might 11.59 on Friday but by golly we'll have released on Friday. I can remember a release of BIP years ago that for some reason we went for 12/31 as a release date ... were we mad? I seem to remember we made it but talk about ridiculous pressure! The latest 10g rollup is out in the wild and available from Oracle support. A bug fixing rollup but worth getting to and know that support will want you to get to it and re-test before going forward on an SR. One simple but very useful fix or enhancement:[Cause of the bug] @ ================== @ Customer reports that despite the clock being shown, end users are clicking @ on the View button repeatedly as the initial generation is taking some time.   @ If the button were to be grayed out then  this would prevent the users @ requesting the report more than  once.  Repeated requests are causing a @ system overload and as this is their Production  instance this is extremely @ important to the customer. @ . @ [The Fix] @ ========= @ Added the logic to disable the button after the user clicks on the "view" @ button and re-enable it when the report is loaded. I told a group of customers once that they have a headache and we have a non-steroidal anti-inflammatory drug, alright, I actually said 'aspirin'. This little gem of a fix helps relieve another little headache that our aspirin was causing. The patch number for all this BIP pain killing is 13399232, enjoy!

  • SnapBird Supercharges Your Twitter Searches

    - by ETC
    Twitter’s default search tool is a bit anemic. If you want to supercharge your Twitter search, fire up web-based search tool SnapBird and dig into your past tweets as well as those of friends and followers. Yesterday I was trying to find a tweet I’d sent some time last year regarding my search for an application that could count keystrokes for inclusion in my review of the app I finally found to fulfill the need, KeyCounter. Searching for it with Twitter’s search tool yielded nothing. One simple search at SnapBird and I nailed it. SnapBird requires no authentication to search public tweets (both your own and those of your friends and follows) but does require authentication in order to search through your sent and received direct messages.

  • Encrypt SSD or not?

    - by JamesBradbury
    My desktop machine is running Ubuntu 12.04 (and will probably stay with it until the next LTS). I've got a new 120GB SSD on the way as my existing 420GB spinning disk. If it makes any difference I'll be dual-booting with Windows 7 across both disks too. I've read some helpful answers here about /home setup and enabling TRIM, which I intend to follow. So most of my /home will be on the SSD, with only photos, videos and music on the spinning disk. The question is, when I reinstall Ubuntu from CD or USB, whether I should encrypt the SSD? Specifically: I'm reading that drive wear isn't much of an issue with modern SSDs as they last decades even if you spam them. Is this true? How big a performance reduction will encrypting cause (I have an i7 Sandybridge, so I guess it can cope)? Is it more important from a security point of view to encrypt an SSD? I think I read somewhere that it may be hard to reliably wipe data. By all means answer even if you only know about one of those things.

  • Why is purchasing Microsoft licences such a daunting task? [closed]

    - by John Nevermore
    I've spent 2 frustrating days jumping through hoops and browsing through different local e-shops for VS (Visual Studio) 2010 Pro. And WHS (Windows Home Server) FPP 2011 licenses. I found jack .. - or to be more precise, the closest I found in my country was WHS OEM 2011 licenses after multiple emails sent to individuals found on Microsoft partners page. Question being, why is it so difficult to get your hands on Microsoft licenses as an individual? Sure, you can get the latest end user operating systems from most shops, but when it comes to development tools or server software you are left dry. And companies that do sell licenses most of the time don't even put up pricing or a self service environment for buying the licenses, you need to have an hawk's eye for that shiny little Microsoft partner logo and spam through bunch of emails not knowing, if you can count on them to get the license or not. Sure, i could whip out my credit card and buy the VS 2010 license on the online Microsoft Shop. Well whippideegoddamndoo, they sell that, but they don't sell WHS 11 licenses. Why does a company make it so hard to buy their products? Let's not even talk about the licensing itself being a pain.

  • Newbie tips, please [closed]

    - by eXeP
    So, I just got a new computer and I want to put Ubuntu on my old laptop. I just need few tips before installing it. 1.Programs, where to download, how to download, what is the "ending" (windows has .exe) 2. How much is command line involved? And where to get the most usual commands? 3.Few programs you recommend (graphics editing, IDE, video player, web browser) 4. Do I have to download drivers when installing new OS? I plan on getting fully rid of Windows. I have no idea of the name of my graphics card, so how do I can get to know what it is if I have to download drivers? (I don't know the name because it's not on the original box, or anywhere on the internet, believe me) 5. When installing new OS does it destroy everything else on the hard drive? 6. Anti-virus, do I need one? I'm not super paranoid, and I don't visit "shady" sites. Please note that I have never used linux, or any other OS than Windows and sorry for my bad english. If this is the wrong place to post this, then please remove this. Thank you.

  • You wouldn&rsquo;t drink 9 year old milk would you?

    - by Jim Duffy
    This is an absolutely brilliant campaign to urge users that its time to move on from IE 6. I like how it puts it terms that everyone can understand and has probably experienced at one time or another. How many times have you opened the milk, took a sniff, and experienced that visceral reaction that accompanies catching a whiff of milk that has turned to the dark side of the force? I call it Darth Vader milk. :-) Of course I’m assuming that you haven’t used IE 6 for a long time now. It is our responsibility as information technology workers to communicate to our friends and family how lame using IE 6 is. Shame them into upgrading if necessary. I don’t care how you get through to them but get through. Tell them that only losers use IE 6. Tell them you’ll cut them out of the your will. Tell them they’re banned from your annual BBQ blowout. Tell them that [insert their favorite celebrity’s name here] thinks people using IE6 are losers.  :-) Seriously, IE6 sucks and blows at the same time and has got to go for a number of reasons including the security leaks that come with using it. Confidentially, I urge them to upgrade for purely selfish reasons. Because I am the first level of computer support for waaaaaay to many of my family members I always advocate they use a current browser (IE 8 or Firefox) and anti-virus software (AVG). Call me selfish but I’d rather not waste my time dealing with a virus or malware that could potentially slip through with IE6. Yes, I’m selfish with my time that way. :-) Have a day. :-|

  • When does implementing MVVM not make sense

    - by Kelly Sommers
    I am a big fan of various patterns and enjoy learning new ones all the time however I think with all the evangelism around popular patterns and anti-patterns sometimes this causes blind adoption. I think most things have individual pros and cons and it's important to educate what the cons are and when it doesn't make sense to make a particular choice. The pros are constantly advocated. "It depends" I think applies most times but the industry does a poor job at communicating what it depends ON. Also many patterns surfaced from inheriting values from previous patterns or have derivatives, which each one brings another set of pros and cons to the table. The sooner we are more aware of the trade off's of decisions we make in software architecture the sooner we make better decisions. This is my first challenge to the community. Even if you are a big fan of said pattern, I challenge you to discover the cons and when you shouldn't use it. Define when MVVM (Model-View-ViewModel) may not make sense in a particular piece of software and based on what reasons. MVVM has a set of pros and cons. Let's try to define them. GO! :)

  • Secunia Personal Software Inspector (PSI) 2.0

    - by TATWORTH
    Secunia Personal Software Inspector is now available in a updated version that is free for personnal use. The home page says "The Secunia PSI is aFREE security tool designed to detectvulnerable andout-dated programs and plug-ins which expose your PC to attacks. Attacks exploiting vulnerable programs and plug-ins are rarely blocked by traditional anti-virus and are therefore increasingly "popular" among criminals. The only solution to block these kind of attacks is to apply security updates, commonly referred to as patches. Patches are offered free-of-charge by most software vendors, however, finding all these patches is a tedious and time consuming task. Secunia PSI automates this and alerts you when your programs and plug-ins require updating to stay secure. Download the Secunia PSI now and secure your PC today - free-of-charge." I have used this for some time on my home PC and have found it to be very useful in identifying required updates. I use Google Chrome but I found that whenever a new version is issued, the old version is not de-installed. Secunia PSI helps me to locate them and get rid of them.

  • How to make my simple round sprite look right in XNA

    - by Joshua Perina
    Ok, I'm very new to graphics programming (but not new to coding). I'm trying to load a simple image in XNA which I can do fine. It is a simple round circle which I made in photoshop. The problem is the edges show up rough when I draw it on the screen even with the exact size. The anti-aliasing is missing. I'm sure I'm missing something very simple: GraphicsDevice.Clear(Color.Black); // TODO: Add your drawing code here spriteBatch.Begin(); spriteBatch.Draw(circle, new Rectangle(10, 10, 10, 10), Color.White); spriteBatch.End(); Couldn't post picture because I'm a first time poster. But my smooth png circle has rough edges. So I found that if I added: spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.NonPremultiplied); I can get a smooth image when the image is the same size as the original png. But if I want to scale that image up or down then the rough edges return. How do I get XNA to smoothly resize my simple round image to a smaller size without getting the rough edges?

  • XNA 2D Spritesheet drawing rendering problem

    - by user24092
    I'm making a tile-based game, using one spritesheet containing all tile graphics. Each tile has a size of 32x32 pixels. The main problem is: when I draw the tile to the screen, if the tile position x and y are not rounded or if scale is activated in spriteBatch.Draw() method (scale != 1.0f), I get some lines of adjacent tiles on the spritesheet into the current tile drawed. I already tried setting SamplerState to PointClamp, removing AntiAlias, but still doesn't work. Here I'll show images of some tests that I made, with a test sprite sheet that I've created (I made a 9x9 spritesheet, with each sprite of size 32x32 containing a unique solid color). Tests: http://img6.imageshack.us/img6/5946/testsqj.png SpriteSheet used: http://imageshack.us/a/img821/1341/tilesm.png Already tried to remove anti-alias, set PointClamp as sampler state, but still getting this issue, XNA keeps drawing part of the adjacent pixels of the texture on the screen. What I want is to get the correct area of the tilesheet texture (as seen in the first test, that gets just the yellow pixels). My question is: Is there any way that I can fix this, WITHOUT adding tile spacing or any other modification involving the tilesheet? Maybe disabling a texture filtering that is done by XNA, or something like that.

  • FOSS Development: Who develops the OS-specific packages?

    - by achristi
    I have a couple of FOSS projects. They can be a bit of a pain to get running unless you've got dependencies in place already, which I figure is par for the course for FOSS projects. We know that each free operating system out there has its own package management systems. A few of them, such as homebrew on Mac OS or AUR on Arch linux are very friendly to community contributions. What I am wondering is, who exactly is expected to contribute packages? Primarily I am concerned with the case of small or developing projects, since it's pretty standard for the big projects to be put in there by the OS maintainers. From my perspective, it is something of a chicken-egg problem, because your software will not make its way into a package system if it does not have users, and it is less likely to gain users if it is not easy to install and use. For the sake of discussion, let's assume that the software in question is actually legitimately useful. I can see where people could create crapware or spam and that should obviously be kept out of any package system. So, in summary, whose job is this? Is it spammy for a FOSS software dev to put his own work into various OS package repositories?

  • Vector-based fonts vs. bitmap fonts in (2d) games?

    - by jmp97
    I know that many games are using bitmap fonts. Which are the advantages for vector-based font rendering / manipulation when compared to bitmap fonts and in which scenarios would they matter the most? Prefer a focus on 2d games when answering this question. If relevant, please include examples for games using either approach. Some factors you might consider: amount of text used in the game scaling of text overlaying glyphs and anti-aliasing general rendering quality font colors and styling user interface requirements localisation / unicode text wrapping and formatting cross-platform deployment 2d vs 3d Background: I am developing a simple falling blocks game in 2d, targeted for pc. I would like to add text labels for level, score, and menu buttons. I am using SFML which uses FreeType internally, so vector-based features are easily available for my project. In my view, font sizes in simple games often don't vary, and bitmap fonts should be easier for cross-platform concerns (font-formats and font rendering quality). But I am unsure if I am missing some important points here, especially since I want to polish the looks of the final game.

  • Triggering Data Changes in N-Tier

    - by Ryan Kinal
    I've been studying n-tier architectures as of late, particularly in VB.NET with Entity Framework and/or LINQ to SQL. I understand the basic concepts, but have been wondering about best practices in regard to triggering CRUD-type operations from user input/action. So, the arcitecture looks something like the following: [presentation layer] - [business layer] - [data layer] - (database) Getting information from the database into the presentation layer is simple and abstracted. It's just a matter of instantiating a new object from the business layer, which in turn uses the data layer to get at the correct information. However, saving (updating and inserting), and deleting seem to require particular APIs on the relevant business objects. I have to assume this is standard practice, unless a business object will save itself on various operations (which seems inefficient), or on disposal (which seems like it just wouldn't work, or may be unwieldy and unreliable). Should my "savable" business objects all implement a particular "ISavable" or "IDatabaseObject" interface? Is this a recognized (anti-)pattern? Are there other, better patterns I should be using that I'm just unaware of? The TLDR question, I suppose, is How does the presentation layer trigger database changes?

  • At the end of my rope

    - by hvgotcodes
    I am a contractor to a big company. Currently, there are three developers on the project, myself included. The problem is the other 2 developers don't really get it. By "it" i mean the following: They don't understand the best practices for the technology we are using. After 6 months of me and others giving them examples there are terrible anti-patterns being used. They are "copy and paste" programmers that produce primarily spaghetti code. They constantly break things, implementing changes but not doing a basic smoke test to see if all is good They refuse/rarely to ask for code-reviews. They refuse/rarely even do basic things like formatting code. No documentation on any classes (jsdocs) Afraid to delete code that doesn't do anything Leave commented code blocks everywhere even though we have version control. I find myself getting more and more frustrated as I format others code, fix bugs, discover functionality that is broken, and create abstractions to remove the spaghetti. I really don't know what to do. I try not to get to frustrated, but it's just a mess. I like these people as people, but I feel like the coding situation is so bad that I could move faster if they simply browsed the web all day. Would it be out of line to ask our manager to review the others svn commit access; commits can only be done after a review by someone who is knowledgeable in what we are doing? As a contractor, I'm not sure if that's the best move. Is there a subtle/not so subtle way of making it clear how many things I am fixing?

  • Need a good quality bitmap rotation algorithm for Android

    - by Lumis
    I am creating a kaleidoscopic effect on an android tablet. I am using the code below to rotate a slice of an image, but as you can see in the image when rotating a bitmap 60 degrees it distorts it quite a lot (red rectangles) – it is smudging the image! I have set dither and anti-alias flags but it does not help much. I think it is just not a very sophisticated bitmap rotation algorithm. canvas.save(); canvas.rotate(angle, screenW/2, screenH/2); canvas.drawBitmap(picSlice, screenW/2, screenH/2, pOutput); canvas.restore(); So I wonder if you can help me find a better way to rotate a bitmap. It does not have to be fast, because I intend to use a high quality rotation only when I want to save the screen to the SD card - I would redraw the screen in memory before saving. Do you know any comprehensible or replicable algorithm for bitmap rotation that I could programme or use as a library? Or any other suggestion? EDIT: The answers below made me think if Android OS had bilinear or bicubic interpolation option and after some search I found that it does have its own version of it called FilterBitmap. After applying it to my paint pOutput.setFilterBitmap(true); I get much better result

  • C++ Succinctly now available!

    - by Michael B. McLaughlin
    Over the summer I worked with SyncFusion to create an eBook based off of my C# to C++ guide for their free Succinctly Series of eBooks. Today the result, C++ Succinctly, was published for download. It is a free (registration required; they make tools and libraries for .NET development so you might get an occasional email from them – I’ve been signed up for a few months and have had maybe 3 emails total so it’s not horrible super spam or anything ) and you can download it as a PDF or a Kindle .MOBI file (or both). I’m excited with how it turned out and enjoyed working with the people at SyncFusion. The book contains a total of 20 code samples, which you can download from BitBucket (there’s a link very early in the book). Almost all of the code is also inline in the book itself so that you don’t need to worry about flipping back and forth between your dev machine and your eReader (but if you want to try to understand a concept better, you can easily download the code, open it up in VS 2012, and play around with it to see what happens when you tinker with things). The code does require Visual Studio 2012 because of its expanded support for C++11 features and since I wrote all of the samples as Console programs for clarity and compactness, you will need a version that supports C++ desktop development (currently VS 2012 Pro, Premium, or Ultimate). Sometime this Fall, Microsoft will be releasing Visual Studio 2012 Express for Windows Desktop which should provide a free way to use the samples. That said, I tested all of the samples with MinGW and only the StorageDurationSample will not compile with it due to the thread-local storage code. If you comment that out then you can compile and run all the samples with MinGW (or using a recent version of GCC in a GNU/Linux environment, or any other C++ compiler that provides the same level of C++11 support that Visual Studio 2012 does). I hope it proves helpful to those of you who choose to check it out!
