• Initial capacity of collection types, i.e. Dictionary, List

  - by Neil N

  Certain collection types in .Net have an optional "Initial Capacity" constructor param. i.e. Dictionary<string, string> something = new Dictionary<string,string>(20); List<string> anything = new List<string>(50); I can't seem to find what the default initial capacity is for these objects on MSDN. If I know I will only be storing 12 or so items in a dictionary, doesn't it make sense to set the initial capacity to something like 20? My reasoning is, assuming the capacity grows like it does for a StringBuiler, which doubles each time the capacity is hit, and each re-allocation is costly, why not pre-set the size to something you know will hold your data, with some extra room just in case? If the initial capacity is 100, and I know I will only need a dozen or so, it seems as though the rest of that allocated RAM is allocated for nothing. Please spare me the "premature optimization" speil for the O(n^n)th time. I know it won't make my apps any faster or save any meaningful amount of memory, this is mostly out of curiosity.

• What kind of users stories should be written in the initial stages of a project?

  - by Domenic

  When just starting a project, you have nothing---no UI, no data layer, nothing in between. Thus, a single story like "users should be able to view their foos" will entail a lot of work. Once you have that story, one like "users should be able to edit their foos" is more realistic, but that first story will involve setting up a UI layer, a presentation logic layer, a domain logic layer, and a data access layer. This doesn't fit with my concept of "tasks": to me, I'd rather have something like the following "tasks": Show dummy data for a user's foos in HTML, derived from JavaScript objects. Set up a presentation logic layer, and connect the JavaScript objects to it. Set up a domain logic layer, and connect the presentation logic layer to it. Set up a data access layer, and connection the domain logic layer to it. Do all of these fall under the single "story" above? If so, I feel like stories are not a terribly useful framework in the early stages of a project. If so, that's fine---I just want to make sure I'm not missing something, since I'm really trying to learn this agile methodology as best I can.

• How do I initialize a Scala map with more than 4 initial elements in Java?

  - by GlenPeterson

  For 4 or fewer elements, something like this works (or at least compiles): import scala.collection.immutable.Map; Map<String,String> HAI_MAP = new Map4<>("Hello", "World", "Happy", "Birthday", "Merry", "XMas", "Bye", "For Now"); For a 5th element I could do this: Map<String,String> b = HAI_MAP.$plus(new Tuple2<>("Later", "Aligator")); But I want to know how to initialize an immutable map with 5 or more elements and I'm flailing in Type-hell. Partial Solution I thought I'd figure this out quickly by compiling what I wanted in Scala, then decompiling the resultant class files. Here's the scala: object JavaMapTest { def main(args: Array[String]) = { val HAI_MAP = Map(("Hello", "World"), ("Happy", "Birthday"), ("Merry", "XMas"), ("Bye", "For Now"), ("Later", "Aligator")) println("My map is: " + HAI_MAP) } } But the decompiler gave me something that has two periods in a row and thus won't compile (I don't think this is valid Java): scala.collection.immutable.Map HAI_MAP = (scala.collection.immutable.Map) scala.Predef..MODULE$.Map().apply(scala.Predef..MODULE$.wrapRefArray( scala.Predef.wrapRefArray( (Object[])new Tuple2[] { new Tuple2("Hello", "World"), new Tuple2("Happy", "Birthday"), new Tuple2("Merry", "XMas"), new Tuple2("Bye", "For Now"), new Tuple2("Later", "Aligator") })); I'm really baffled by the two periods in this: scala.Predef..MODULE$ I asked about it on #java on Freenode and they said the .. looked like a decompiler bug. It doesn't seem to want to compile, so I think they are probably right. I'm running into it when I try to browse interfaces in IntelliJ and am just generally lost. Based on my experimentation, the following is valid: Tuple2[] x = new Tuple2[] { new Tuple2<String,String>("Hello", "World"), new Tuple2<String,String>("Happy", "Birthday"), new Tuple2<String,String>("Merry", "XMas"), new Tuple2<String,String>("Bye", "For Now"), new Tuple2<String,String>("Later", "Aligator") }; scala.collection.mutable.WrappedArray<Tuple2> y = scala.Predef.wrapRefArray(x); There is even a WrappedArray.toMap() method but the types of the signature are complicated and I'm running into the double-period problem there too when I try to research the interfaces from Java.

• How to back up initial state of external backup drive?

  - by intuited

  I've picked up an HP Simplesave external drive. It comes with some fancy software that is of no use to me because I don't use Windows. Like many current consumer-targeted backup drives, the backup software is actually contained on the drive itself. I'd like to save the drive's initial state so that I can restore it if I decide to sell it. The backup box itself is somewhat customized: in addition to the hard drive device, it presents a CDROM-like device on /dev/sr0. I gather that the purpose of this cdrom device is to bootstrap via Windows autoplay the backup application which lives on the disk itself. I wouldn't suppose any guarantees about how it does this, so it seems important to preserve the exact state of the disk. The drive is formatted with a single 500GB NTFS partition. My initial thought was to use dd to dump the disk (/dev/sdb) itself, but this proved impractical, as the resulting file was not sparse. This seemed to be because the NTFS empty space is not filled with zeroes, but with a repeating series of 16 bytes. I tried gzipping the output of dd. This reduced to the file to a manageable size — the first 18GB was compressed to 81MB, versus 47MB to tarball the contents of the mounted filesystem — but it was very slow on my admittedly somewhat derelict Pentium M processor. The time to do that first 18GB was about 30 minutes. So I've resorted to dumping the disk state and partition data separately. I've dumped the partition state with sfdisk -d /dev/sdb > sfdisk.-d.out I've also created a compressed image of the NTFS partition (the only one on the disk) with ntfsclone --save-image --output - /dev/sdb1 | gzip -c > ntfsclone.img.gz Is there anything else I should do to ensure that I can restore the precise original state of the drive?

• How do I remove initial indents on numbered lists?

  - by Peter

  In Word 2007 I want all numbers in a numbered list to be down the LH margin in line with the paragraphs. When a numbered list is selected, the numbers 1,2,3 are indented by a default 0.63cm. Ctrl-Shift-M will shift this indent back to the left margin. How do I permanently remove that initial indent and save that change to the normal template so that all new documents have zero indent on a newly inserted numbered list? (Same issue in Word 2010)

• Can I emulate hs-hide-initial-comment-block in vim?

  - by Jason Baker

  In emacs, there's a helpful command called hs-hide-initial-comment-block that will fold a comment block if it is the very first thing in a file. This way, I can get straight to the code without having to worry about the licensing comment. Is there any way to do this in vim?

• How do I set the Initial Directory on an OpenFileDIalog to the users `Downloads` folder in C#

  - by JMK

  Ok so I have an OpenFileDialog and I want to set the initial directory to the users 'Download' folder. This is an internal application and, therefore, I am sure that the user will be using Windows 7. var ofd = new OpenFileDialog(); //This doesn't work ofd.InitialDirectory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "Downloads"); //This doesn't work either ofd.InitialDirectory = @"%USERPROFILE%\Downloads"; ofd.Filter = "Zip Files|*.zip"; ofd.ShowDialog(); txtFooBar.Text = ofd.FileName; I have tried the above so far and neither work. No Exception is thrown, it just doesn't set the initial directory to the downloads folder. Where am I going wrong? Thanks

• What initial modelling/design activities on Agile Projects do you do??

  - by dalton

  When developing an application using agile techniques, what if any initial modelling/architecture activities do you do, and how do you capture that knowledge?? I'm not after a bullet list about XP, Scrum, Crystal, DSDM..etc as I'm familiar with the methodologies. But what do you do above and beyond the guidance given by these. I find I work best by thinking the system through first, but also like the benefits of timeboxing, story cards, pairing, tdd. The closest thing I've seen so far is Scott Ambler's Initial Architecture Modelling, but was wondering what alternatives are used out there?

• Video card not detected in POST on initial boot.

  - by Jeff M

  I have a minor problem with my desktop computer after cleaning it out for dust. When I first boot up the computer, the video card does not get detected so I can't see anything. In POST, I'm getting the "can't detect video card" beeps. The boot sequence continues normally, just without video. However, if I restart it (using the restart button) anytime after POST, it would boot up normally. I have no reason to think that the motherboard, video card or PSU got damaged in the process. It was working fine before, works fine after resetting. Took all the necessary precautions while cleaning. On the initial boot, I can hear the video card's fan power up but immediately power down and try again one more time only to fail. After the beep, resetting gets everything running and sounding normally. I've reseated the card a couple of times and reset the BIOS but doesn't seem to help. I'm hoping I won't have to take it out and remove and reinstall everything again. Does anyone recognize these symptoms to know exactly what the problem is? My guess is that the video card isn't getting enough juice initially to be running stable to be detected. I just don't know what I did (or didn't do) to get it to be in this state. It's not a high priority thing for me at the moment, just means I have to always reset it after initially turning it on but will eventually remove everything and reinstall if it comes to that. I don't think the specs are relevant here but just in case, here's the relevant stuff: Motherboard: Gigabyte P35-DS3P Video: EVGA GeForce 8600 GTS PSU: Antec True Power Trio 650W Built ~2 years ago, still running well

• When modern computers boot, what initial setup of RAM do they execute, and how does it exactly work?

  - by user272840

  I know the title reeks of confusion, and some of you might assume I am just wondering about how the computer boots in general, but I'm not. But I'll sort this out for you people now: 1.Onboard firmware is how mostly all modern computer devices work, whether or not with EFI/UEFI(even without "onboard firmware", older computers still employed bank switching, or similar methods with snap-in firmware, cartridges, etc.) 2.On startup there is no "programs" running in the traditional sense yet, i.e. no kernel, OS, user-applications; all of the instructions, especially the very first instruction, is specified by the Instruction Pointer, I am guessing. How is the IP/PC/etc. set to first point to an address for a BIOS/firmware/etc. instruction, and how do the BIOS instructions map themself out in memory prior to startup? 3.Aside from MMIO, BIOS uses certain RAM addresses to have instructions. The big ? comes in when I ask this ... how does BIOS do this? Conclusion: I am assuming that with the very first instruction there is an initial hardware setup for BIOS prior to complete OS bootup. What I want to know is if it's hardware engineered to always work this way, if there's another step in this bootup method I am missing, a gap of information I am unaware of, or how this all works from the very first instruction, and the RAM data itself.

• ISPconfig3 + CentOS 6.2 , confused on how to move forward after initial install?

  - by Damainman

  I installed ISPCONFIG3 on centos 6.2 using the great guide on howtoforge.com. Everything is up and running and I can access ISPCONFIG via a browser. However I am not sure how to move forward with the initial setup so I can setup the very first account and get my website live. Details: Only have 1 server, the centos+ispconfig is running on a virtual machine of XEN XCP. I setup the server name to be server1.mydomain.com. I only have 2 usable ips. I plan to use them as follows: xx.xx.xx.01 : For my website and the websites of all accounts I add. xx.xx.xx.02 : For ns1.mydomain.com and ns2.mydomain.com (Yea I know they should be different ips at different locations, but this is what I have to work with at the moment.... ) I registered the nameservers at my registrar with the .02 ip. I want to use bind and ISPconfig to run the DNS on my server itself and not via my registrar. Right now if I go to the .01 IP it shows the centos+apache successful install page. So to break it down basically I am not sure where to start when it comes to: (What to consider and what to do to setup the first domain on the server) Telling bind to use the name server domains with .02. Setting up my First website(which will be my main website) in ISPconfig so mydomain.com resolves properly to my server. Make it so when you go to the .01 IP, it either redirects or shows the contents of my main website. (If this can't be done, then any advice is appreciated) Making sure that when I add a new domain, it automatically puts in the proper information for the domain so it points to the right mail, database, dns, entry. If I overlooked a tutorial then please feel free to let me know, and any advice would be greatly appreciated. Some of the tutorials I found were not specific to doing everything on only one server with Centos+Apache+Bind. Right now all I did was install centos and install ISPconfig3. Trying to move forward correctly so I don't mess up everything I did by not knowing what to do. Thank you in advance!!

• Unable to fetch initial output of "defrag" commad in Windows Server 2008 R2 in WOW64 environment.

  - by Ganesh

  Hi All, [Application & code back ground] I have an MFC application which is executing on Windows Server 2008 R2 in WOW64 environment. In which on user input it defragments the selected drive on the disk. I initiated the process(.i.e. cmd /c defrag –v c:) of defragmentation using the CreateProcess() API, along with this to display output of the process on the main screen I created the pipe using CreatePipe() API. I used PeekNamedPipe() & ReadFile() API to get the output and display. [Problem Area] When the process is launched I am not getting the initial output as below: Microsoft Disk fragmenter Copyright © 2007 Microsoft Crop. Invoking defragmentation on (C:)…. I constantly monitor the output of the process while it is under progress but not able to get any thing as output in the pipe. It seem the process is not doing any thing and appears as if the application is not responding. But after certain period of time, once the process is about to completed I get result along with the initial data. [Sample code] //Pipe created if(0 == ::CreatePipe(&l_hStdOutRead, &l_hStdOutWrite, &l_SecurityAttribute, (DWORD)NULL)) { //Error code } //Process created/launched if (0 == ::CreateProcess(NULL, (LPTSTR)f_csProcessName, &l_stSecurityAttributes, NULL, TRUE, CREATE_NO_WINDOW, NULL,NULL, &l_StartupInfo, &l_CmdPI)) { //Error code } //Read output if (0 == ::PeekNamedPipe(m_hStdOutRead, l_cArrPeekBuffer, (DWORD)NULL, (LPDWORD)NULL, &l_dwAvailable, (LPDWORD)NULL)) { //Return to read again } if (MPLUSFALSE == ::ReadFile(m_hStdOutRead, l_cArrOutput, min(BUFFER_SIZE - 2, l_dwAvailable), &l_dwRead, NULL) || !l_dwRead) { //error code } //Display data. If any one is aware of similar problem or worked on the similar issue please let me know the solution. Thanks in Advance, Ganesh

• Possible to modify DOM during/before initial DOM parsing?

  - by AMO

  Is it possible to modify the DOM during or before the initial DOM parsing? Or do I have to wait until the DOM is parsed and built before interacting with it? More specifically, is it possible to hinder a script element in DOM from running using userscripts/content scripts or similar in chrome or firefox? Tried using eventListeners on DOMNodeInserted before the DOM is parsed, but these are only fired after the DOM is built.

• ASP.NET mvc 2 Validation always shows errors on initial page load.

  I've searched around a lot, and honed this problem down to this case: I'm using the PRG pattern, pragmatically I'm using the same DTO for my post/get actions. It looks like when I have the dto with the data annotation attributes in the get action parameter list, the validation is always displaying errors, every time on initial page load. In some cases this could be desired behavior if you put asterisks in the error message, but how do I get rid of it? Thanks in advance.

• apache mod_rewrite rule in httpd.conf for modifying some paths, but not others

  - by wallyk

  I'm having quite a challenge creating an appropriate rewrite rule for Apache/2.2.14 on Fedora 10. I'm working through the CodeIgniter-Doctrine tutorial which uses an .htaccess file. (Search for Removing “index.php” from CodeIgniter urls about 10% down.) But since that's not recommended for a production server, I'm trying to tweak it to work in /etc/httpd/conf/httpd.conf. <VirtualHost *:80> ServerName ci_doctrine DocumentRoot /var/www/html/ci_doctrine ErrorLog /var/log/httpd/cid-error_log CustomLog /var/log/httpd/cid-access_log common <IfModule mod_rewrite.c> RewriteEngine on RewriteLog /var/log/httpd/cid_rewrite RewriteLogLevel 9 # RewriteCond ^/css/style.css$ (these have bad syntax, but that's beside the point) # RewriteRule ^/css/style.css$ /css/style.css [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /index.php/$1 [L] </IfModule> <IfModule !mod_rewrite.c> ErrorDocument 404 /ci_doctrine/index.php </IfModule> </VirtualHost> It seems like the tutorial .htaccess rules properly test for existing files and then not alter the URL in such cases, but the rewrite log says that the conditions are true (that is, the file does not exist) even though it's there. 127.0.0.1 -

• Join + IEqualityComparer<T> and HashCode

  - by Jesus Rodriguez

  Im writing my own LINQ reference but Im getting troubles with some of the more complicated operators implementations. There is a Join implementation that takes a IEqualityComparer Im getting just crazy. Im trying to understand it first before I write (obviously) Image this two lists: List<string> initials = new List<string> {"A", "B", "C", "D", "E"}; List<string> words = new List<string> {"Ant", "Crawl", "Pig", "Boat", "Elephant", "Arc"}; Nothing weird here. I want to join both lists by the Initial, something like: Initial=A Word=Ant Initial=A Word=Arc Initial=B Word=Boat ... I need a comparator, I wrote this: public class InitialComparator : IEqualityComparer<string> { public bool Equals(string x, string y) { return x.StartsWith(y); } public int GetHashCode(string obj) { return obj[0].GetHashCode(); } } The Join itself: var blah = initials.Join(words, initial => initial, word => word, (initial, word) => new {Initial = initial, Word = word}, new InitialComparator()); It's the first time Im using HashCodes, after a good session of debugging I see that every word go to the comparator and look at its HashCode, if another word has the same HashCode it calls equals. Since I want to compare just the initial I though that I just need the first letter Hash (Am I wrong?) The thing is that this is not working correctly. Its says that "Ant" and "Arc" are equals, Ok, its comparing every word in the same list or not, But it adds only the last word it finds, in this case Arc, ignoring Ant and Ant is equals to "A" too... If I put "Ant" and "Ant" it add both. In short, What is the way of doing something like that? I know that Im doing something wrong. Thank you.

Additional Information: - Framework setup check failed on all the nodes - Cause: Cause Of Problem Not Available   - Action: User Action Not Available Summary of the failed nodes fedora - Version of exectask could not be retrieved from node "fedora"   - Cause: Cause Of Problem Not Available   - Action: User Action Not Available To eliminate this error I have tried various measures including the change of permission of the tmp folder and restarting the computer but none is working. Plz someone help me out of this. Any kind of help will be appreciated...

• Ideas for loading initial data in an iPhone application?

  - by Derek Clarkson

  Hi all, In my app I want to load some initial data to show the user how it works. The app uses a CoreData managed sqllite db. SO far I've thought of 3 options: Write code into a class to programmatically create the data. Create a xml file in the apps resources and load through a NSXmlParser whose delegate creates the entries in the sqllite db. Same as option #2, but use a json file and bring in a 3rd party lib to read it. Are there other options I have not found yet? and given that I'm talking about perhaps 6 records per table when there are 3 tables, which would you choose?

• Are all "GET" requests to JSF "Initial Request"s?

  - by Pradyumna

  Hi, In JSF 1.1, I am assuming that GET requests are treated as initial requests (resulting in the creation of a new view), and POST requests are treated as Postbacks (resulting in the restoration of the old view). However, my application is behaving differently - it restores the same old view even for GET requests. Why does this happen? Is there a way to force the creation of a new view for GET requests? (My state-saving method is 'server'. I'm using MyFaces with JSP, and I have a t:saveState on a managed bean in the view) Regards, Pradyumna

• Force initial Google Drive sync with a non-empty folder?

  - by Terrance Shaw

  I upgraded my iMac with an SSD last night and restored from a Time Capsule backup. Everything is now working substantially zippier and overall better, with the exception of one thing: Google Drive refuses to continue to sync with the Google Drive folder that it'd been using before the upgrade, and I ultimately ended up having to just delete the folder and let it resync from scratch to get past its stubborn error (alternatively, I suppose I could've simply moved the contents, set the path to the now-empty folder, then moved them back). Is there any way to get past this particular issue (for future reference), or is it something that Google put in place to ensure that a new user doesn't go and specify their root drive as the backup destination?

  I have a hostgator account, and i just ran 5 tests from pingdom, and got .9, 1.5, 3, 5, and 9 seconds. Is this kind of fluctuation normal?
