• SSD/HDD not exceeding 120 MB/s

  - by skiwi

  SO here is the situation: First this was my old PC, it had a 2x 1TB RAID 0 and a Corsair Force 3 SSD in it. This were the old speeds, measured by HDTune Pro. 2x 1TB RAID 0: Corsair Force 3 SSD Then my dad got my PC and we had several issues, in the end turned out both RAID and SSD controller were malfunctioning causing BlueScreens on 100% load. Removed the RAID 0, but leaving the HDD's intact and bought an Samsung 840 EVO 120GB, though the Corsair SSD is still in the system, just not as sytem disk anymore. 1TB HDD (one of them): Corsair SSD: Samsung SSD: We did not assemble the PC ourselves, so answering some technical questions might be more difficult, though we will do our best. First thing we noticed is that the Samsung 840 EVO is no where reaching it's advertised speed, even an Samsung 840 250GB (non-EVO) is reaching 350 MB/s in my own PC. Then we noticed that both SSD's are capped at 120 MB/s exactly, not sure if this is being caused by HDTune Pro, but very unlikely. And even worse, the Corsair Forza 3 was running faster before the system got reassembled. Does anyone have any clue what is going on?

• Windows Server 2003 (w/Exchange) move to new machine

  - by James Booker

  I have an ageing domain controller (the only one on a 10-pc network) which needs rebooting often. I have a Dell Poweredge 2850 server doing nothing, so I'd like to move the DC to that, but here's the catch - I don't have Win2k Server Std install media any more as it's been lost. I purchased "Easus Todo Backup Advanced Server" which claims to be able to recover to dissimilar metal, but it's not quite working (although I don't think it's the product's fault) I know the server and PERC RAID card are good because I installed Ubuntu on the logical drive (4 x 72GB disks RAID 5) no problems. I've booted frmo the Easus Todo backup CD (which is WinPE based) and recovered to the logical disk on the RAID (after installing driver inside the WinPE environment from a NAS drive) The problem is when I boot the server, I can get the OS selection menu, but any option results in a blank screen, with no errors. I figure this is probably because the driver wasn't installed on the old machine (which is IDE-based (i know, i know!) and doesn;t have a RAID controller) I've booted from the CD and copied the mraid35x.sys file to the c:\windows\system32\drivers folder on the recovered system, but it makes no difference. I made a boot.ini with rdisks 0-10 defined, and booting from each of these resulted in a file error (i.e. 'this isn't a real disk') - the only disk that gets any response (the blank screen) is multi(0)disk(0)rdisk(0)partition(1) which just gives me the blank black screen and no disk activity. Is there any way I can force the drvier to be installed on the source system (so i can do a full backup again), i've tried right-clicking the oemsetup.inf and clicking install, but it didn't actually do anything. I attempted to force it with the 'Add new hardware' wizard and forcing with the 'have disk' option but it still gave me no hardware to select. Also I've got an identical machine running WinXP which uses the PERC driver successfully (which was obviously done at install time) and the boot.ini settings are the same : multi(0)disk(0)rdisk(0)partition(1) Any ideas would be appreciated.

• Data recovery on working hard drive

  - by emgee

  So I have a 5 bay hot swap SATA enclosure that's connected to a Silicon Image-based SATA adapter in a computer. It's running XP Pro. There are two 1.5TB hard drives in slots 1 and 2 respectively, set up using RAID 1 using the the Silicon Image utility. There are also two 1TB drives in bays 3 and 4, also set to RAID 1 the same way. The partitions for both RAID arrays are Dynamic partitions. A few days back, there was a bare hard drive that needed some files copied off of, so it was popped it in bay 5, that bay to pass-through, and the copied data off of it. Later, I noticed that my 1.5TB drives no longer showed up in windows. In the Silicon Image utility, the drives showed up fine, no error. However, in Device Manager, it shows the RAID 1 array as uninitialized. It shows up as the right size, etc., but nothing else. There's no sign of anything wrong with either drive, so I'm not sure what happened exactly. I'm not the only one who has access to that computer, so it is possible there is something else done to it that I don't know of. There's quite a lot of data on it still, and if at all possible, I'd prefer to not send it to Ontrack. Does anyone know of software that would restore the partitions, keeping in mind that it's a Windows LDM partition? I have access to a variety of Operating Systems, so something that would work on Mac, Windows or Linux would be acceptable. The programs I usually use are not compatible with LDM.

• Linux Server partitioning

  - by user1717735

  There's a lot of infos about this out there, but there's also a lot of contradictory infos… That's why i need some advices about it. So far, on the servers i had home for test (or even "home production") purposes i didn't really care about partitioning and i configured all in / + a swap partition, over RAID 0. Nevertheless, this pattern can't apply to production servers. I have found a good starting point here, but also it depends on what the servers will be used for… So basically, i have a server on which there will be apache, php, mysql. It will have to handle file uploads (up to 2GB) and has 2*2TB hard drive. I plan to set : / 100GB, /var 1000GB (apache files and mysql files will be here), /tmp 800GB (handles the php tmp file) /home 96GB swap 4GB All of this if of course over RAID 1. But actually, it's not a big deal if I lose data being uploaded, so would it be interesting mounting /tmp over raid 0 while maintaining the rest over raid 1? Sounds complicated…

• Why Haven’t NFC Payments Taken Off?

  - by David Dorf

  With the EMV 2015 milestone approaching rapidly, there’s been renewed interest in smartcards, those credit cards with an embedded computer chip.  Back in 1996 I was working for a vendor helping Visa introduce a stored-value smartcard to the US.  Visa Cash was debuted at the 1996 Olympics in Atlanta, and I firmly believed it was the beginning of a cashless society.  (I later worked on MasterCard’s system called Mondex, from the UK, which debuted the following year in Manhattan). But since you don’t have a Visa Cash card in your wallet, it’s obvious the project never took off.  It was convenient for consumers, faster for merchants, and more cost-effective for banks, so why did it fail?  All emerging payment systems suffer from the chicken-and-egg dilemma.  Consumers won’t carry the cards if few merchants accept them, and merchants won’t install the terminals if few consumers have cards. Today’s emerging payment providers are in a similar pickle.  There has to be enough value for all three constituents – consumers, merchants, banks – to change the status quo.  And it’s not enough to exceed the value, it’s got to be a leap in value, because people generally resist change.  ATMs and transit cards are great examples of this, and airline kiosks and self-checkout systems are to a lesser extent. Although Google Wallet and ISIS, the two leading NFC payment platforms in the US, have shown strong commitment, there’s been very little traction.  Yes, I can load my credit card number into my phone then tap to pay, but what was the incremental value over swiping my old card?  For it to be a leap in value, it has to offer more than just payment, which I can do very easily today.  The other two ingredients are thought to be loyalty programs and digital coupons, but neither Google nor ISIS really did them well. Of course a large portion of the mobile phone market doesn’t even support NFC thanks to Apple, and since it’s not in their best interest that situation is unlikely to change.  Another issue is getting access to the “secure element,” the chip inside the phone where accounts numbers can be held securely.  Telco providers and handset manufacturers own that area, and they’re not willing to share with banks.  (Host Card Emulation, which has been endorsed by MasterCard and Visa, might be a solution.) Square recently gave up on its wallet, and MCX (the group of retailers trying to create a mobile payment platform) is very slow out of the gate.  That leaves PayPal and a slew of smaller companies trying to introduce easier ways to pay. But is it really so cumbersome to carry and swipe (soon to insert) a credit card?  Aren’t there more important problems to solve in the retail customer experience?  Maybe Apple will come up with some novel way to use iBeacons and fingerprint identification to make payments, but for now I think we need to focus on upgrading to Chip-and-PIN and tightening security.  In the meantime, NFC payments will continue to struggle.

• My computer freezes irregularly

  - by Manhim

  My computer started to freeze at irregular times for 3 weeks now. Please note that this question change with each things that i try. (For additional details) What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. Sometimes my G-15 LCD screen flickers and caracters gets caried around temporary under heavy load. Now, most of the times, the BIOS hard disks boot order gets reversed for some reason and I have to put it to the right one and save each times I boot. (Might be unrelated, not sure, but it first started yesterday) Sometimes the BIOS doesn't detect my 750GB hard drive plugged in SATA1. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 45-55. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu Ran 6 short different CPU stress test on Fedora 15 (Haven't found any complete stress testers for Linux) and it didn't crash. Changed the thermal paste to some Artic Silver 5 for my CPU and stress tested the CPU, temperature was at 50 idle, then 64 highest and slowly went down to 62 during the test. Ran some stress testing with a temporary graphic card and it went ok. Ran furmark stress test with my original graphic card and it freezed again. GPU had a temp of 74C, a CPU temp of 58C and a mobo temp of 40C or 45C (Dunno which one it is from SpeedFan). Ran a furmark stress test and a CPU stress test at the same time, results: http://pastebin.com/2t6PLpdJ I have been using my computer without stressing it for about 2 hours now and no crashes yet. I also have disabled the AMD Cool'n'quiet function on the BIOS for a more regular power to the CPU. When I ran Furmark without C'n'q my computer didn't freeze but I had a "Driver Kernel Error" that have recovered (And Furmark crashed) all that while running a CPU stress test. The computer eventually frozed without me being at it, but this time my screen just went on sleep and I couldn't wake it. Using the stability tester in nTune my computer freezed again (In the same manner as before). I notived that Speedfan gives me a -12V of -16.97V and a -5V of -8.78V. I wonder if these numbers are reliable and if they are good or bad. I have swapped my G-15 with another basic USB keyboard (HP) and I have ran furmark for about 10 minutes with a CPU stability test running each 60 seconds for 30 seconds and my computer haven't crashed yet. Ran some more extended tests without my G-15 and it freezed like it usually do. Removed the nForce Hard disk controler. Disabled command queuing in the NVIDIA nForce SATA Controller for both port 0 and port 1 (Errors from the logs) Used CPUID HwMonitor, here are the voltages: http://pastebin.com/dfM7p4jV Changed some configurations in the motherboard BIOS: Disabled PEG Link Mode, Changed AI Tuning to Standard, Disabled the 1394 Controller, Disabled HD Audio, Disabled JMicron RAID controller and Disabled SATA Raid. When it happens When I play video games (Mostly) When I play flash games (Second most) When I'm looking at my desktop background (It rarely happens when I have a window open, but it does, sometimes) When my Graphic card and my CPU are stressed. Sometimes when my Graphic card is stressed. Never happenned while stressing only the CPU. Sometimes when my CPU is stressed. Specs Windows Seven x64 Home Premium Motherboard: M2N-SLI Deluxe CPU: AMD Phenom 9950 x2 @ 2.6GHz Memory: Kingston 4x2GB Dual Channel (Pretty basic memory sticks) Hard drives: Was 2x250GB (Western digital caviar) in raid-0 + 1TB (WD caviar black), I replaced the raid array with a 750GB (WD caviar black) [Yes I removed the array from the raid configurations] 750W Power supply No overcloking. Ever. There have been some power-downs like 4-5 weeks ago, but the problem didn't start immediately after. (I wasn't home, so my computer got shut-down) Event logs (Warnings, errors and critical errors) for the last 24 hours: http://pastebin.com/Bvvk31T7 My current to-try list Reinstall the drivers and software 1 by 1 and do extensive stress testing between each. Update the BIOS firmware to the most recent stable one. Change my motherboard. Status updates Keeping only the last 3 (28/06 04pm) More stress testing and still pass the tests. (28/06 03pm) Been stress testing for 10 minute straight now and 5 minutes with both CPU and GPU being stressed at the same time. (28/06 03pm) Stress-testing right now, so far no problems. A little hope Tests with Furmark and Prime95. Testing Windows bare-bone: 30 Minutes stress, no freeze. Installing an Anti-virus and some software, restarting computer. Testing with Anti-virus and some software (No drivers installed): 30 Minutes stress, no freeze. Installing audio drivers, restarting computer. Testing with the audio drivers: 30 Minutes stress, no freeze. Installing the latest graphic drivers from EVGA's website (without 3d vision since I don't use it), restarting computer. Testing with the graphic drivers: 30 Minutes stress, no freeze. Configuring Windows to my liking and installing more softwares. In this situation, how can I successfully pin-point the current hardware problem? (If it's a hardware problem) Because I don't really have the budget to just forget and replace everything. I also don't really have hardware to test-replace current hardware.

• CFBundleDocumentTypes and iPad camera connection kit (SD reader)

  - by Kendall Helmstetter Gelner

  I am trying to register a custom document type in an iPad app, with the hopes that I can be prompted to work with files on an SD card attached to the iPad through the camera connection kit. Does anyone know if this is currently possible (or even for sure if it's not possible)? I was hoping that the Camera tab in Photos would use a document interaction controller for types it did not understand, but it seems like Photos does not check for alternate handlers at all - I tried also registering support for the jpg type but was not prompted when using photos and loading in JPG images from an SD card. There is an SD reader app called Zoomit that appears to read many different types from an SD card: http://currentphotographer.com/zoomit-application-enabled-sd-card-reader-for-the-iphone/ But it seems that involves custom hardware, that differs from the standard SD reader.

• Let system time determine animation speed, not program FPS

  - by Anders

  I'm writing a card game in ActionScript 3. Each card is represented by an instance of a class extending movieclip exported from Flash CS4 that contains the card graphics and a flip animation. When I want to flip a card I call gotoAndPlay on this movieclip. When the frame rate slows down all animations take longer to finish. It seems Flash will by default animate movieclips in a way that makes sure all frames in the clip will be drawn. Therefor, when the program frame rate goes below the frame rate of the clip, the animation will be played at a slower pace. I would like to have an animation always play at the same speed and as a consequence always be shown on the screen for the same amount of time. If the frame rate is too slow to show all frames, frames are dropped. Is is possible to tell Flash to animate in this way? If not, what is the easiest way to program this behavior myself?

• Android : Bitmap save to location

  - by Chrispix

  I am working on a function to download an image from a web server, redisplay it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice? My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a Fileoutput stream to write the data. The other option I have is it use MediaStore : MediaStore.Images.Media.insertImage(getContentResolver(), bm, barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image"); Which works fine to save to SD card, but does not allow you to customize the folder. Any assistance would be very much appreciated. Thank you in advance.

• Stop Excel from changing cell contents, ever

  - by Enable Manual-Correct

  I work with card numbers, like credit card and ID numbers. We do not do any calculations with card numbers, obviously. They are "text." I format them as text, I type them like text. I know how that works. Excel doesn't care. 16 digit card numbers get their last digit turned into a zero, changed into scientific notation, stupid stuff that I did not tell Excel to do. I need to do things like Find/Remove spaces from cells in files downloaded from our currently imperfect web-system. The system sends me files with 16 digit numbers, cells formatted as text, but due to bugs there are spaces at the end. I do Find/Remove all spaces and all my card numbers are transformed into scientific notation and the last digit turned into a 0. THEY ARE TEXT, they are formatted as text, I yelled into the screen that they are text, why does Excel refuse to acknowledge that they are text? (I would rather find a way to stop Excel's action than find a way to tell our programmers to put an apostrophe in every cell) How do I make it so that Excel just STOPS doing anything that I didn't tell it to do? Or at least stop it from doing anything to numbers it doesn't like. Maybe I can write a macro for whenever it discovers "Uhoh I should change that number to something different!" I'll make it format that cell to text a thousand times instead. Give me an error when I try calculating with a number larger than 15 digits, make my computer explode violently, that's fine. Just stop changing the numbers. Is it possible? I have many thousands of numbers that need changing in many different scenarios. I just want to stop it from trying to help. I can't understand why that would be difficult. I have 2007, but answers for other versions would be great as well. Thank you!

  The new MacBookPros come with two graphic adapters, the Intel HD Graphics, and the NVIDIA GeForce GT 330M. OS X switches back and forth between them, depending on the workload, detection of an external monitor, or activation of Rosetta. I want to get my feet wet with CUDA programming, and unfortunately the CUDA SDK doesn't seem to take care of this back-and-forth switching. When Intel is active, no CUDA device gets detected, and when the NVidia card is active, it gets detected. So my current work-around is to use the little tool gfxCardStatus (http://codykrieger.com/gfxCardStatus/) to force the card on or off, just as I need it, but that's not satisfactory. Does anybody here know what the Apple-blessed, Apple-recommended way is to (1) detect the presence of a CUDA card, (2) to activate this card when present?

• Silverlight 3 data-binding child property doesn't update

  - by sonofpirate

  I have a Silverlight control that has my root ViewModel object as it's data source. The ViewModel exposes a list of Cards as well as a SelectedCard property which is bound to a drop-down list at the top of the view. I then have a form of sorts at the bottom that displays the properties of the SelectedCard. My XAML appears as (reduced for simplicity): <StackPanel Orientation="Vertical"> <ComboBox DisplayMemberPath="Name" ItemsSource="{Binding Path=Cards}" SelectedItem="{Binding Path=SelectedCard, Mode=TwoWay}" /> <TextBlock Text="{Binding Path=SelectedCard.Name}" /> <ListBox DisplayMemberPath="Name" ItemsSource="{Binding Path=SelectedCard.PendingTransactions}" /> </StackPanel> I would expect the TextBlock and ListBox to update whenever I select a new item in the ComboBox, but this is not the case. I'm sure it has to do with the fact that the TextBlock and ListBox are actually bound to properties of the SelectedCard so it is listening for property change notifications for the properties on that object. But, I would have thought that data-binding would be smart enough to recognize that the parent object in the binding expression had changed and update the entire binding. It bears noting that the PendingTransactions property (bound to the ListBox) is lazy-loaded. So, the first time I select an item in the ComboBox, I do make the async call and load the list and the UI updates to display the information corresponding to the selected item. However, when I reselect an item, the UI doesn't change! For example, if my original list contains three cards, I select the first card by default. Data-binding does attempt to access the PendingTransactions property on that Card object and updates the ListBox correctly. If I select the second card in the list, the same thing happens and I get the list of PendingTransactions for that card displayed. But, if I select the first card again, nothing changes in my UI! Setting a breakpoint, I am able to confirm that the SelectedCard property is being updated correctly. How can I make this work???

• How do you encrypt parts of a file separately using pgp?

  - by Collin Anderson

  I would like to encrypt credit card numbers on a web server as they come in using PGP. I would then like to be able to export all of the credit card numbers and other information in one file that can be easily decrypted using standard PGP software. Is it possible to take the encrypted credit card numbers and join them with other encrypted data and be able to decrypt the entire file? Basically is this true? D(E(x) + E(y)) = x + y Where '+' means string concatenation.

• Why are my Fluent NHibernate SubClass Mappings generating redundant columns?

  - by Brook

  I'm using Fluent NHibernate 1.x build 694, built against NH 3.0 I have the following entities public abstract class Card { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } public virtual Product Product { get; set; } public virtual Sprint Sprint { get; set; } } public class Story:Card { public virtual double Points { get; set; } public virtual int Priority { get; set; } public virtual IList<Task> Tasks { get; set; } } And the following mappings public class CardMap:ClassMap<Card> { public CardMap() { Id(c => c.Id) .Index("Card_Id"); Map(c => c.Name) .Length(50) .Not.Nullable(); Map(c => c.Description) .Length(1024) .Not.Nullable(); References(c=>c.Product) .Not.Nullable(); References(c=>c.Sprint) .Nullable(); } } public class StoryMap : SubclassMap<Story> { public StoryMap() { Map(s => s.Points); Map(s => s.Priority); HasMany(s => s.Tasks); } } When I generate my Schema, the tables are created as follows Card --------- Id Name Description Product_id Sprint_id Story ------------ Card_id Points Priority Product_id Sprint_id What I would have expected would have been to see the columns Product_id and Sprint_id ONLY in the Card table, not the Story table. What am I doing wrong or misunderstanding?

• I trying to backreference using the sed command

  - by Paul

  I am relative new to shell scripting and sed. I need to substitute a pattern, globably, but I also need to remember (or save) part of the pattern and use it later in the same substitute command. The saved pattern will be varible, so I need to use a wild card. For example, input message=trt:GetAudioSourcesRequest/> and I want to end up with something like input message=trt:GetAudioSourcesRequest PAUL/GetAudioSourcesRequest/> but the function string "GetAudioSourcesRequest" will change (in length also) throughtout the file, so I need a wild card, e.g. sed -i "s/input message=trt:<wild card in here>/>/input message=trt:<print wild card> PAUL/<print wild card>/> I have managed to get the following command to nearly do what I want but it is too rigid. It only stores a 4 syllable pattern so if I have a function name such as GetProfileRequest, this doesn't work echo "input message=\"trt:GetAudioSourcesRequest\"/>" | sed 's/input message=\"trt:\([A-Z][a-z]*\)\([A-Z][a-z]*\)\([A-Z][a-z]*\)\([A-Z][a-z]*\).*/input message=\"trt:\1\2\3\4\ PAUL\/\1\2\3\4"\/\>/g' This outputs input message="trt:GetAudioSourcesRequest PAUL/GetAudioSourcesRequest"/> Which is ok but when I use GetProfileRequest this doesn't. I have come accross \W and [^[:alnum:]] or [[:alnum:]] but I don't how to use them Thanks in advance.

• How to create a controllable flip effect (flip as far (and fast) as you drag) of an UIView

  - by allisone

  I have a card (a flashcard you could say) What I can do: On fingersweeping over the flashcard the card gets turned. It's happening by detecting touchesBegan and touchesMoved and then I do stuff like [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (left) { [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:self.flashCardView cache:YES]; }else{ [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.flashCardView cache:YES]; } What I can't do (but want to): I want to somehow drag the flip. Imagine this, you have a flashcard and you think you know the answer, you start flipping the card around because you want to see if you are correct, but then... no stop... you hesitate, turn back the card to the way it was, rethink, get the real answer and then finally flip to see that you were right to hesitate. Now I only have: once you start flipping, you can't stop it.

• Why isn't the "this." command needed in this constructor? (java)

  - by David

  I'm reading a book about java. It just got to explaining how you create a class called "deck" which contains an array of cards as its instance variable(s). Here is the code snippit: class Deck { Card[] cards; public Deck (int n) { cards = new Card[n]; } } why isn't the this. command used? for example why isn't the code this: class Deck { Card[[] cards; public Deck (int n) { this.cards = new Card[n]; } }
