• DevDays ‘00 The Netherlands day #2

  - by erwin21

  Day 2 of DevDays 2010 and again 5 interesting sessions at the World Forum in The Hague. The first session of the today in the big world forum theater was from Scott Hanselman, he gives a lap around .NET 4.0. In his way of presenting he talked about all kind of new features of .NET 4.0 like MEF, threading, parallel processing, changes and additions to the CLR and DLR, WPF and all new language features of .NET 4.0. After a small break it was ready for session 2 from Scott Allen about Tips, Tricks and Optimizations of LINQ. He talked about lazy and deferred executions, the difference between IQueryable and IEnumerable and the two flavors of LINQ syntax. The lunch was again very good prepared and delicious, but after that it was time for session 3 Web Vulnerabilities and Exploits from Alex Thissen. This was no normal session but more like a workshop, we decided what kind of subjects we discussed, the subjects where OWASP, XSS and other injections, validation, encoding. He gave some handy tips and tricks how to prevent such attacks. Session 4 was about the new features of C# 4.0 from Alex van Beek. He talked about Optional- en Named Parameters, Generic Co- en Contra Variance, Dynamic keyword and COM Interop features. He showed how to use them but also when not to use them. The last session of today and also the last session of DevDays 2010 was about WCF Best Practices from Gerben van Loon. He talked about 7 best practices that you must know when you are going to use WCF. With some quick demos he showed the problem and the solution for some common issues. It where two interesting days and next year i sure will be attending again.

• When too much encapsulation was reached

  - by Samuel

  Recently, I read a lot of gook articles about how to do a good encapsulation. And when I say "good encapsulation", I don't talk about hiding private fields with public properties; I talk about preventing users of your Api to do wrong things. Here is two good articles about this subject: http://blog.ploeh.dk/2011/05/24/PokayokeDesignFromSmellToFragrance.aspx http://lostechies.com/derickbailey/2011/03/28/encapsulation-youre-doing-it-wrong/ At my job, the majority a our applications are not destined to other programmers but rather to the customers. About 80% of the application code is at the top of the structure (Not used by other code). For this reason, there is probably no chance ever that this code will be used by other application. An example of encapsulation that prevent user to do wrong thing with your Api is to return an IEnumerable instead of IList when you don't want to give the ability to the user to add or remove items in the list. My question is: When encapsulation could be considered like too much of purism object oriented programming while keeping in mind that each hour of programming is charged to the customer? I want to do good code that is maintainable, easy to read and to use but when this is not a public Api (Used by other programmer), where could we put the line between perfect code and not so perfect code? Thank you.

• After force-installing a 32-bit deb failed, how can I install the 64-bit version?

  - by TryTryAgain

  I tried to dpkg -i --force-architecture google-earth-stable_i386.deb and it failed. But now when I try to install the amd64.deb it fails saying dpkg: error processing google-earth-stable_current_amd64.deb (--install): google-earth-stable: 6.2.2.6613-r0 (Multi-Arch: no) is not co-installable with google-earth-stable:i386 6.2.2.6613-r0 (Multi-Arch: no) which is currently installed Errors were encountered while processing: google-earth-stable_current_amd64.deb somehow it thinks the i386 version is installed. No google-earth files or directories even exist. sudo dpkg --configure -a outputs: dpkg: dependency problems prevent configuration of google-earth-stable:i386: google-earth-stable:i386 depends on lsb-core (= 3.2). dpkg: error processing google-earth-stable:i386 (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: google-earth-stable:i386 so it does exist in some capacity. sudo apt-get -f install does nothing out of the ordinary: Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 10 not upgraded. The weird thing is that synaptic doesn't show any google earth package available let alone installed, nothing under the broken filter either. I have also tried sudo apt-get autoremove and sudo apt-get autoclean So, my question: How can I get rid of this issue?

• SQLAuthority News – Presenting at Virtual Tech Days TechEd Pre-Con – February 9, 2011

  - by pinaldave

  I will be presenting on following subject on Virtual Tech Days TechEd Pre-Con – February 9, 2011. Auditing Made Easy: Change Tracking and Change Data Capture Date and Time: February 9, 2011 11:45am-12:45pm Location: Online In this fast paced demo oriented session we will go over few of concept which are related to real life problem at customers. We often see developers and DBA looking for details like who has dropped the table, who has last modified any object as well what was actually modified. SQL Server 2008 has all the answers. It has various new methods for Auditing where not only you can know details about what was changed as well know who changed it as well. In addition to that we can capture way more details configuring Auditing. We can also work prevent changes if proper policy management is configured. If you have ever attended my session on this subject earlier, this is going to absolutely new session and very much demo oriented. There is going to be quiz at the end of the session and I promise that if you attend the session, you will get all the answers correct.

• Implementing a modern web application with Web API on top of old services

  - by Gaui

  My company has many WCF services which may or may not be replaced in the near future. The old web application is written in WebForms and communicates straight with these services via SOAP and returns DataTables. Now I am designing a new modern web application in a modern style, an AngularJS client which communicates with an ASP.NET Web API via JSON. The Web API then communicates with the WCF services via SOAP. In the future I want to let the Web API handle all requests and go straight to the database, but because the business logic implemented in the WCF services is complicated it's going to take some time to rewrite and replace it. Now to the problem: I'm trying to make it easy in the near future to replace the WCF services with some other data storage, e.g. another endpoint, database or whatever. I also want to make it easy to unit test the business logic. That's why I have structured the Web API with a repository layer and a service layer. The repository layer has a straight communication with the data storage (WCF service, database, or whatever) and the service layer then uses the repository (Dependency Injection) to get the data. It doesn't care where it gets the data from. Later on I can be in control and structure the data returned from the data storage (DataTable to POCO) and be able to test the logic in the service layer with some mock repository (using Dependency Injection). Below is some code to explain where I'm going with this. But my question is, does this all make sense? Am I making this overly complicated and could this be simplified in any way possible? Does this simplicity make this too complicated to maintain? My main goal is to make it as easy as possible to switch to another data storage later on, e.g. an ORM and be able to test the logic in the service layer. And because the majority of the business logic is implemented in these WCF services (and they return DataTables), I want to be in control of the data and the structure returned to the client. Any advice is greatly appreciated. Update 20/08/14 I created a repository factory, so services would all share repositories. Now it's easy to mock a repository, add it to the factory and create a provider using that factory. Any advice is much appreciated. I want to know if I'm making things more complicated than they should be. So it looks like this: 1. Repository Factory public class RepositoryFactory { private Dictionary<Type, IServiceRepository> repositories; public RepositoryFactory() { this.repositories = new Dictionary<Type, IServiceRepository>(); } public void AddRepository<T>(IServiceRepository repo) where T : class { if (this.repositories.ContainsKey(typeof(T))) { this.repositories.Remove(typeof(T)); } this.repositories.Add(typeof(T), repo); } public dynamic GetRepository<T>() { if (this.repositories.ContainsKey(typeof(T))) { return this.repositories[typeof(T)]; } throw new RepositoryNotFoundException("No repository found for " + typeof(T).Name); } } I'm not very fond of dynamic but I don't know how to retrieve that repository otherwise. 2. Repository and service // Service repository interface // All repository interfaces extend this public interface IServiceRepository { } // Invoice repository interface // Makes it easy to mock the repository later on public interface IInvoiceServiceRepository : IServiceRepository { List<Invoice> GetInvoices(); } // Invoice repository // Connects to some data storage to retrieve invoices public class InvoiceServiceRepository : IInvoiceServiceRepository { public List<Invoice> GetInvoices() { // Get the invoices from somewhere // This could be a WCF, a database, or whatever using(InvoiceServiceClient proxy = new InvoiceServiceClient()) { return proxy.GetInvoices(); } } } // Invoice service // Service that handles talking to a real or a mock repository public class InvoiceService { // Repository factory RepositoryFactory repoFactory; // Default constructor // Default connects to the real repository public InvoiceService(RepositoryFactory repo) { repoFactory = repo; } // Service function that gets all invoices from some repository (mock or real) public List<Invoice> GetInvoices() { // Query the repository return repoFactory.GetRepository<IInvoiceServiceRepository>().GetInvoices(); } }

• Edit the Windows Live Writer Custom Dictionary

  - by Matthew Guay

  Windows Live Writer is a great tool for writing and publishing posts to your blog, but its spell check unfortunately doesn’t include many common tech words.  Here’s how you can easily edit your custom dictionary and add your favorite words. Customize Live Writer’s Dictionary Adding an individual word to the Windows Live Writer dictionary works as you would expect.  Right-click on a word and select Add to dictionary. And changing the default spell check settings is easy too.  In the menu, click Tools, then Options, and select the Spelling tab in this dialog.  Here you can choose your dictionary language and turn on/off real-time spell checking and other settings. But there’s no obvious way to edit your custom dictionary.  Editing the custom dictionary directly is nice if you accidently add a misspelled word to your dictionary and want to remove it, or if you want to add a lot of words to the dictionary at once. Live Writer actually stores your custom dictionary entries in a plain text file located in your appdata folder.  It is saved as User.dic in the C:\Users\user_name\AppData\Roaming\Windows Live Writer\Dictionaries folder.  The easiest way to open the custom dictionary is to enter the following in the Run box or the address bar of an Explorer window: %appdata%\Windows Live Writer\Dictionaries\User.dic   This will open the User.dic file in your default text editor.  Add any new words to the custom dictionary on separate lines, and delete any misspelled words you accidently added to the dictionary.   Microsoft Office Word also stores its custom dictionary in a plain text file.  If you already have lots of custom words in it and want to import them into Live Writer, enter the following in the Run command or Explorer’s address bar to open Word’s custom dictionary.  Then copy the words, and past them into your Live Writer custom dictionary file. %AppData%\Microsoft\UProof\Custom.dic Don’t forget to save the changes when you’re done.  Note that the changes to the dictionary may not show up in Live Writer’s spell check until you restart the program.  If it’s currently running, save any posts you’re working on, exit, and then reopen, and all of your new words should be in the dictionary. Conclusion Whether you use Live Writer daily in your job or occasionally post an update to a personal blog, adding your own custom words to the dictionary can save you a lot of time and frustration in editing.  Plus, if you’ve accidently added a misspelled word to the dictionary, this is a great way to undo your mistake and make sure your spelling is up to par!

• Correct For Loop Design

  - by Yttrill

  What is the correct design for a for loop? Felix currently uses if len a > 0 do for var i in 0 upto len a - 1 do println a.[i]; done done which is inclusive of the upper bound. This is necessary to support the full range of values of a typical integer type. However the for loop shown does not support zero length arrays, hence the special test, nor will the subtraction of 1 work convincingly if the length of the array is equal to the number of integers. (I say convincingly because it may be that 0 - 1 = maxval: this is true in C for unsigned int, but are you sure it is true for unsigned char without thinking carefully about integral promotions?) The actual implementation of the for loop by my compiler does correctly handle 0 but this requires two tests to implement the loop: continue: if not (i <= bound) goto break body if i == bound goto break ++i goto continue break: Throw in the hand coded zero check in the array example and three tests are needed. If the loop were exclusive it would handle zero properly, avoiding the special test, but there'd be no way to express the upper bound of an array with maximum size. Note the C way of doing this: for(i=0; predicate(i); increment(i)) has the same problem. The predicate is tested after the increment, but the terminating increment is not universally valid! There is a general argument that a simple exclusive loop is enough: promote the index to a large type to prevent overflow, and assume no one will ever loop to the maximum value of this type.. but I'm not entirely convinced: if you promoted to C's size_t and looped from the second largest value to the largest you'd get an infinite loop!

• Ubuntu 12.04 Install - Black Screen - No Grub - Have run Boot Repair Disk

  - by Pat

  Day 4 of my purgatory. History: Had problems with live CD at first, had to set the "nomodeset" option ... and then it worked fine. Installed Ubuntu "Alongside" Windows XP from live CD (NOT wubi) Upon reboot after installation, I get the BIOS ... and then a black screen. If I hit shift after the BIOS screen I get text that says "loading GRUB ..", but then no GRUB ... just a black screen. What I have tried to do: Total re-installation ... 3 times now. Also tried with wubi, same black screen. Have gone back to the normal (non-wubi) install. After installation, I tried re-booting the live cd ... and trying to change GRUB file using: sudo gedit /etc/default/grub ... to "nomodeset" and "timeout=10" ... but won't let me save my changes because I'm using the live cd "in memory" system and don't have permissions to the disks (I think). I tried logging in ... but it won't let me. I then read many posts on this site. I'm stuck. This morning, I ran the "boot repair disk". Results here: http://paste.ubuntu.com/1132333/ What I think is wrong: Since I can get the live CD to run (perfectly) with the "nomodeset" option, I think all I need to do is get to GRUB to change that ... but I can't get to GRUB. Appreciate any advice. Pat Day 5 ... I downloaded "Super Grub 2 Disk" from: http://www.supergrubdisk.org/super-grub2-disk/ This looks promising. I can boot the disk and it brings me to a GRUB program that allows me to: 1) Boot to Windows ... which works 2) Boot to Ubuntu ... which does NOT work When I choose boot to Ubuntu, I get lines across the screen which is an obvious video card problem. Likely because I need to set the "nomodeset" option. So, I attempted to use super grub2 to edit the grub file ... but it is TOTALLY different than the Ubuntu grub file ... and I don't know where to put the "nomodeset" option. Still stuck ... The bottom line is that: 1) I need to edit /etc/default/grub on sda(1) ... which is my boot drive ... to add the "nomodeset" option 2) To do that I need to get into grub ... but, I can't. Holding down shift just echo's "loading grub .." and then takes me to a black screen 3) I can boot to the live CD by setting nomodeset .... but I cannot access the hard disk as root ... I can't save my changes! Can anyone tell me how to login as root for the filesystem from the live CD ... so I can edit the grub file on the HARD DISK ... and then run update-grub??

• Preventing battery from charging

  - by intuited

  I'm running on UPS power and would like to prevent the laptop's battery from charging, to increase the amount of power available to other devices. Is there a way to do this? update The machine is a Dell Latitude D400. If people want more details, just ask. Also, I'm gathering that I need to explain my desired setup a little better. I've gotten a bunch of suggestions about taking the battery out. I'm not sure if people are suggesting to take the battery out while the machine is running — this, as I understand, is not a good idea with most laptops — or to just remove the battery altogether. The latter option is not optimal, because ideally I'd like to use the 30-60 minutes of power in the laptop battery and then switch over to UPS power. The details of the switch-over may constitute a separate question, but if I can't find a way to keep the laptop battery from charging, then removing the battery from the machine altogether may be the best way to do this. I'm not sure yet if this machine will run without a battery, but I'll check that out. Other than the laptop, the UPS is just supporting a cable modem and router and a USB hub. Again in the idealized version of this setup, all the power management changes would be automated, i.e. not require replugging anything or pressing Fn-keys. I'd like the machine to start using laptop battery power when apcupsd indicates that the UPS A/C is out, and then start using UPS power, but not charging the battery, when the battery is almost depleted.

• Atheros wireless not working

  - by Chandru1

  I have been struggling hard since i have installed Ubuntu 10.10 but it has been difficult for me to get my wifi working. So here is what i tried. First i checked whether i have the driver using the ifconfig command and it shows the wireless lan driver as wlan0. Next, i tried the command iwlist wlan0 scanning by becoming the root which gave me the output as no scan results. Next, i visited this link https://help.ubuntu.com/community/WifiDocs/Driver/Atheros to see as to what problem my laptop may have. I do own have an ath5k chipset. And as i followed the instructions in the above link in one of the blacklist-ath_pci.conf file had this written in it. For some Atheros 5K RF MACs, the madwifi driver loads buts fails to correctly initialize the hardware, leaving it in a state from which ath5k cannot recover. To prevent this condition, stop madwifi from loading by default. Use Jockey to select one driver or the other. (Ubuntu: #315056, #323830 I am not that good at Linux but i have given it a try. I am desperate to have my wifi working and i would be glad if this community could help.

• HPCM 11.1.2.x - Outline Optimisation for Calculation Performance

  - by Jane Story

  When an HPCM application is first created, it is likely that you will want to carry out some optimisation on the HPCM application’s Essbase outline in order to improve calculation execution times. There are several things that you may wish to consider. Because at least one dense dimension for an application is required to deploy from HPCM to Essbase, “Measures” and “AllocationType”, as the only required dimensions in an HPCM application, are created dense by default. However, for optimisation reasons, you may wish to consider changing this default dense/sparse configuration. In general, calculation scripts in HPCM execute best when they are targeting destinations with one or more dense dimensions. Therefore, consider your largest target stage i.e. the stage with the most assignment destinations and choose that as a dense dimension. When optimising an outline in this way, it is not possible to have a dense dimension in every target stage and so testing with the dense/sparse settings in every stage is the key to finding the best configuration for each individual application. It is not possible to change the dense/sparse setting of individual cloned dimensions from EPMA. When a dimension that is to be repeated in multiple stages, and therefore cloned, is defined in EPMA, every instance of that dimension has the same storage setting. However, such manual changes may not be preserved in all cases. Please see below for full explanation. However, once the application has been deployed from EPMA to HPCM and from HPCM to Essbase, it is possible to make the dense/sparse changes to a cloned dimension directly in Essbase. This can be done by editing the properties of the outline in Essbase Administration Services (EAS) and manually changing the dense/sparse settings of individual dimensions. There are two methods of deployment from HPCM to Essbase from 11.1.2.1. There is a “replace” deploy method and an “update” deploy method: “Replace” will delete the Essbase application and replace it. If this method is chosen, then any changes made directly on the Essbase outline will be lost. If you use the update deploy method (with or without archiving and reloading data), then the Essbase outline, including any manual changes you have made (i.e. changes to dense/sparse settings of the cloned dimensions), will be preserved. Notes If you are using the calculation optimisation technique mentioned in a previous blog to calculate multiple POVs (https://blogs.oracle.com/pa/entry/hpcm_11_1_2_optimising) and you are calculating all members of that POV dimension (e.g. all months in the Period dimension) then you could consider making that dimension dense. Always review Block sizes after all changes! The maximum block size recommended in the Essbase Database Administrator’s Guide is 100k for 32 bit Essbase and 200k for 64 bit Essbase. However, calculations may perform better with a larger than recommended block size provided that sufficient memory is available on the Essbase server. Test different configurations to determine the most optimal solution for your HPCM application. Please note that this blog article covers HPCM outline optimisation only. Additional performance tuning can be achieved by methodically testing database settings i.e data cache, index cache and/or commit block settings. For more information on Essbase tuning best practices, please review these items in the Essbase Database Administrators Guide. For additional information on the commit block setting, please see the previous PA blog article https://blogs.oracle.com/pa/entry/essbase_11_1_2_commit

• Dependencies lib32asound2 [duplicate]

• Camera frustum calculation coming out wrong

  - by Telanor

  I'm trying to calculate a view/projection/bounding frustum for the 6 directions of a point light and I'm having trouble with the views pointing along the Y axis. Our game uses a right-handed, Y-up system. For the other 4 directions I create the LookAt matrix using (0, 1, 0) as the up vector. Obviously that doesn't work when looking along the Y axis so for those I use an up vector of (-1, 0, 0) for -Y and (1, 0, 0) for +Y. The view matrix seems to come out correctly (and the projection matrix always stays the same), but the bounding frustum is definitely wrong. Can anyone see what I'm doing wrong? This is the code I'm using: camera.Projection = Matrix.PerspectiveFovRH((float)Math.PI / 2, ShadowMapSize / (float)ShadowMapSize, 1, 5); for(var i = 0; i < 6; i++) { var renderTargetView = shadowMap.GetRenderTargetView((TextureCubeFace)i); var up = DetermineLightUp((TextureCubeFace) i); var forward = DirectionToVector((TextureCubeFace) i); camera.View = Matrix.LookAtRH(this.Position, this.Position + forward, up); camera.BoundingFrustum = new BoundingFrustum(camera.View * camera.Projection); } private static Vector3 DirectionToVector(TextureCubeFace direction) { switch (direction) { case TextureCubeFace.NegativeX: return -Vector3.UnitX; case TextureCubeFace.NegativeY: return -Vector3.UnitY; case TextureCubeFace.NegativeZ: return -Vector3.UnitZ; case TextureCubeFace.PositiveX: return Vector3.UnitX; case TextureCubeFace.PositiveY: return Vector3.UnitY; case TextureCubeFace.PositiveZ: return Vector3.UnitZ; default: throw new ArgumentOutOfRangeException("direction"); } } private static Vector3 DetermineLightUp(TextureCubeFace direction) { switch (direction) { case TextureCubeFace.NegativeY: return -Vector3.UnitX; case TextureCubeFace.PositiveY: return Vector3.UnitX; default: return Vector3.UnitY; } } Edit: Here's what the values are coming out to for the PositiveX and PositiveY directions: Constants: Position = {X:0 Y:360 Z:0} camera.Projection = [M11:0.9999999 M12:0 M13:0 M14:0] [M21:0 M22:0.9999999 M23:0 M24:0] [M31:0 M32:0 M33:-1.25 M34:-1] [M41:0 M42:0 M43:-1.25 M44:0] PositiveX: up = {X:0 Y:1 Z:0} target = {X:1 Y:360 Z:0} camera.View = [M11:0 M12:0 M13:-1 M14:0] [M21:0 M22:1 M23:0 M24:0] [M31:1 M32:0 M33:0 M34:0] [M41:0 M42:-360 M43:0 M44:1] camera.BoundingFrustum: Matrix = [M11:0 M12:0 M13:1.25 M14:1] [M21:0 M22:0.9999999 M23:0 M24:0] [M31:0.9999999 M32:0 M33:0 M34:0] [M41:0 M42:-360 M43:-1.25 M44:0] Top = {A:0.7071068 B:-0.7071068 C:0 D:254.5584} Bottom = {A:0.7071068 B:0.7071068 C:0 D:-254.5584} Left = {A:0.7071068 B:0 C:0.7071068 D:0} Right = {A:0.7071068 B:0 C:-0.7071068 D:0} Near = {A:1 B:0 C:0 D:-1} Far = {A:-1 B:0 C:0 D:5} PositiveY: up = {X:0 Y:0 Z:-1} target = {X:0 Y:361 Z:0} camera.View = [M11:-1 M12:0 M13:0 M14:0] [M21:0 M22:0 M23:-1 M24:0] [M31:0 M32:-1 M33:0 M34:0] [M41:0 M42:0 M43:360 M44:1] camera.BoundingFrustum: Matrix = [M11:-0.9999999 M12:0 M13:0 M14:0] [M21:0 M22:0 M23:1.25 M24:1] [M31:0 M32:-0.9999999 M33:0 M34:0] [M41:0 M42:0 M43:-451.25 M44:-360] Top = {A:0 B:0.7071068 C:0.7071068 D:-254.5585} Bottom = {A:0 B:0.7071068 C:-0.7071068 D:-254.5585} Left = {A:-0.7071068 B:0.7071068 C:0 D:-254.5585} Right = {A:0.7071068 B:0.7071068 C:0 D:-254.5585} Near = {A:0 B:1 C:0 D:-361} Far = {A:0 B:-1 C:0 D:365} When I use the resulting BoundingFrustum to cull regions outside of it, this is the result: Pass PositiveX: Drew 3 regions Pass NegativeX: Drew 6 regions Pass PositiveY: Drew 400 regions Pass NegativeY: Drew 36 regions Pass PositiveZ: Drew 3 regions Pass NegativeZ: Drew 6 regions There are only 400 regions to draw and the light is in the center of them. As you can see, the PositiveY direction is drawing every single region. With the near/far planes of the perspective matrix set as small as they are, there's no way a single frustum could contain every single region.

• What is the most time-effective way to monitor & manage threats from bots and/or humans?

  - by CheeseConQueso

  I'm usually overwhelmed by the amount of tools that hosting companies provide to track & quantify traffic data and statistics. I'm equally overwhelmed by the countless flavors of malicious 'attacks' that target any and every web site known to man. The security methods used to protect both the back and front end of a website are documented well and are straight-forward in terms of ease of implementation and application, but the army of autonomous bots knows no boundaries and will always find a niche of a website to infest. So what can be done to handle the inevitable swarm of bots that pound your domain with brute force? Whenever I look at error logs for my domains, there are always thousands of entries that look like bots trying to sneak sql code into the database by tricking the variables in the url into giving them schema information or private data within the database. My barbaric and time-consuming plan of defense is just to monitor visitor statistics for those obvious patterns of abuse and either ban the ips or range of ips accordingly. Aside from that, I don't know much else I could do to prevent all of the ping pong going on all day. Are there any good tools that automatically monitor this background activity (specifically activity that throws errors on the web & db server) and proactively deal with these source(s) of mayhem?

• Monitor and Control Memory Usage in Google Chrome

  - by Asian Angel

  Do you want to know just how much memory Google Chrome and any installed extensions are using at a given moment? With just a few clicks you can see just what is going on under the hood of your browser. How Much Memory are the Extensions Using? Here is our test browser with a new tab and the Extensions Page open, five enabled extensions, and one disabled at the moment. You can access Chrome’s Task Manager using the Page Menu, going to Developer, and selecting Task manager… Or by right clicking on the Tab Bar and selecting Task manager. There is also a keyboard shortcut (Shift + Esc) available for the “keyboard ninjas”. Sitting idle as shown above here are the stats for our test browser. All of the extensions are sitting there eating memory even though some of them are not available/active for use on our new tab and Extensions Page. Not so good… If the default layout is not to your liking then you can easily modify the information that is available by right clicking and adding/removing extra columns as desired. For our example we added Shared Memory & Private Memory. Using the about:memory Page to View Memory Usage Want even more detail? Type about:memory into the Address Bar and press Enter. Note: You can also access this page by clicking on the Stats for nerds Link in the lower left corner of the Task Manager Window. Focusing on the four distinct areas you can see the exact version of Chrome that is currently installed on your system… View the Memory & Virtual Memory statistics for Chrome… Note: If you have other browsers running at the same time you can view statistics for them here too. See a list of the Processes currently running… And the Memory & Virtual Memory statistics for those processes. The Difference with the Extensions Disabled Just for fun we decided to disable all of the extension in our test browser… The Task Manager Window is looking rather empty now but the memory consumption has definitely seen an improvement. Comparing Memory Usage for Two Extensions with Similar Functions For our next step we decided to compare the memory usage for two extensions with similar functionality. This can be helpful if you are wanting to keep memory consumption trimmed down as much as possible when deciding between similar extensions. First up was Speed Dial”(see our review here). The stats for Speed Dial…quite a change from what was shown above (~3,000 – 6,000 K). Next up was Incredible StartPage (see our review here). Surprisingly both were nearly identical in the amount of memory being used. Purging Memory Perhaps you like the idea of being able to “purge” some of that excess memory consumption. With a simple command switch modification to Chrome’s shortcut(s) you can add a Purge Memory Button to the Task Manager Window as shown below.  Notice the amount of memory being consumed at the moment… Note: The tutorial for adding the command switch can be found here. One quick click and there is a noticeable drop in memory consumption. Conclusion We hope that our examples here will prove useful to you in managing the memory consumption in your own Google Chrome installation. If you have a computer with limited resources every little bit definitely helps out.

• Customize SharePoint list using InfoPath2010 form Part4

  - by ybbest

  Customize SharePoint list using InfoPath2010 form Part1 Customize SharePoint list using InfoPath2010 form Part2 Customize SharePoint list using InfoPath2010 form Part3 In this post, I’d like to show you how to create print functionality in InfoPath for SharePoint list. The print functionality is provided out of box in InfoPath form library; however it is not available in SharePoint list. Here are the steps to create the print functionality.You can download the new form here. 1. Create print page in the list by first copy and paste the displayifs.aspx and rename the file to Printifs.aspx. 2. Open the page in the SharePoint designer and copy the following javascript to the PlaceHolderTitleAreaClass ContentPlaceHolder. <script type="text/javascript"> $(document).ready(function(){ $("[id^='Ribbon']").hide(); $(".s4-title").hide(); $("[id='s4-leftpanel']").hide(); $("[id='s4-ribbonrow']").hide(); $("[id='s4-titlerow']").hide(); $("[id='s4-titlerow']").css("height", "0px"); $("body").css("background-color", "white"); $("body").css("zoom", "135%"); $("[id='MSO_ContentTable']").css("margin-left", "0px"); $("[id='MT-BodyContent']").css("width", "900px"); $(".MT-BodyArea").css("width", "900px"); $("[id='MT-Layout']").css("width", "900px"); $(".ms-bodyareacell").css("width", "900px"); $(".s4-wpTopTable").css("border", "none"); $("[id$='XmlFormView']").css("margin-left", "-80px"); $("body").css("margin-top", "-30px"); $(":contains('CAPEX')").css("border", "5px solid #FFCC00"); window.print(); }); </script> 3. Open InfoPath form for the list and create a field called PrintLink 4. Set the default value of printLink that points to the print page I just created before with the query string id.You can download the formula for the default value here. 5. Add a new image that looks like Print button on the display view, then I can set the url to the Print link Field. (The reason I did not use button is that you cannot set the navigate url for the button). 6.Set the url of the image to the PrintLInk field. 7.Next , create the print view. 8. Copy the contents from the display view to print view 9. Finally, go to the printifs.aspx and edit the InfoPath web part to set the view to PrintView. 9. Republish you form you will see the form as shown below 10. If you click the Print button, you will see the print page and print dialog,you can also add the company logo in the print page using css as well. 11.To deploy the customization,you can use the backup and restore content database approach , you can get more details from my previous blog post here.

• Clientside anticheating in multiplayer game 1vs1

  - by garnav

  I'm developing a simple card game, where there will be a matchmaking system that will put you against another human player. This will be the only game mode available, a 1vs1 against another human, no AI. I want to prevent cheating as much as possible. I have already read a lot of similar questions here and I already know that I cannot trust the client and I have to make all verifications server side. I intend to have a server (need one for the matchmaking anyway) and I intend to make some verifications server side but if I want to check everything server side this makes my server to be able to keep track of the state of all current games and check every action, and I don't have the money/infrastructure to support that server. My idea is to make clients check and verify some of the actions made by their opponent* and if they find some illegal action notify the possible cheating to the server and make the server verify it. This will still require my server to keep track of all current games, but it will save resources only checking some things that cannot be checked at client side(like card order in the deck) and only checking other things when they are actually wrong. *(only those they can check with out allowing themselves cheating! for example:they can't check if the played card was in hand cos that will need them to know all cards in hand) Summing up, my questions are: is this a viable approach? will I actually save resources doing this or the extra complexity in the server and client for exchanging this messages is not worth it? do you know any game that has successfully or unsuccessfully tried a similar approach? Thanks all for reading and answering

• How to work around a possible XNA Game Studio or Windows Phone SDK install failure on Windows 8

  - by Laurent Bugnion

  I am not sure if you guys know Aaron Stebner. Aaron works at Microsoft, and has pulled thorns from my side many many times already. His blog is at http://blogs.msdn.com/b/astebner and it is a gold mine of tips and tricks to debug and solve many cryptic issues happening during installation and removal of programs. For example, Aaron taught me how to remove programs that do not appear in the Programs and Features list, amongst many other things. The last nugget I used from Aaron’s blog saved my butt just before a presentation where I had to run both Visual Studio 10 with the Windows Phone SDK, and Visual Studio 11 for WinRT development. Of course this had to be on Windows 8. Unfortunately when you install the Windows Phone SDK on Windows 8, you may (or may not, I saw both scenarios) encounter an issue with XNA, and the installation fails. Unfortunately, even if you don’t use XNA in your apps, this will prevent even normal Windows Phone app development. Fortunately, Aaron has a fix for that. I hope that this helps spread the word, and increase Aaron’s blog’s visibility! Happy coding, Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Repairing The Visual Studio 2012 UI

  - by Ken Cox [MVP]

  I have sympathy for ‘Softies who don’t like the controversial ‘Metro’ UI changes but are afraid to say so. After all, who wants to commit a CLM (Career-Limiting Move) by declaring that the Emperor has no clothes (or gradients) and that ALL CAPS IN MENUS ARE DUMB? Talk about power! Here’s a higher-up (anyone got a name?) who has enforced a flat, monochrome, uninteresting user interface in Visual Studio 2012  that has been damned with faint praise by consumers. The pushback must have been enormous. Some ‘Softies disengage from the raging debate with, “It’s not my decision” while others feebly point out that the addition of some colour pixels in the icons is a real improvement over the beta version. True, I guess. With the UI pretty much locked, its down to repairing the damage. Fortunately, some Empire dissident has leaked the news to a blogger that  those SHOUTING CAPs aren’t hardcoded afterall: How To Prevent Visual Studio 2012 ALL CAPS Menus And so it goes. By RTM, I’m sure there will be many more add-ons to help us ‘de-Metro’ VS 2012 and recreate our favourite Visual Studio 2010 themes for it.
