• "Misaligned partition" - Should I do repartition (how?)

  - by RndmUbuntuAmateur

  Tried to install Ubuntu 12.04 from USB-stick alongside the existing Win7 OS 64bit, and now I'm not sure if install was completely successful: Disk Utility tool claims that the Extended partition (which contains Ubuntu partition and Swap) is "misaligned" and recommends repartition. What should I do, and if should I do this repartition, how to do it (especially if I would like not to lose the data on Win7 partition)? Background info: A considerably new Thinkpad laptop (UEFI BIOS, if that matters). Before install there were already a "SYSTEM_DRV" partition, the main Windows partition and a Lenovo recovery partition (all NTFS). Now the table looks like this: SYSTEM_DRV (sda1), Windows (sda2), Extended (sda4) (which contains Linux (sda5; ext4) and Swap (sda6)) and Recovery (sda3). Disk Utility Tool gives a message as follows when I select Ext: "The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested." There were couple of problems during the install, which I describe below, in the case they happen to be relevant. Installer claimed that it recognized existing OS'es fine, so I checked the corresponding option during the install. Next, when it asked me how to allocate the disk space, the first weird thing happened: the installer give me a graphical "slide" allocate disk space for pre-existing Win7 OS and new Ubuntu... but it did not inform me which partition would be for Ubuntu and which for Windows. ..well, I decided to go with the setting installer proposed. (not sure if this is relevant, but I guess I'd better mention it anyway - the previous partition tools have been more self-explanatory...) After the install (which reported no errors), GRUB/Ubuntu refused to boot. Luckily this problem was quite straightforwardly resolved with live-Ubuntu-USB and Boot-Repair ("Recommended repair" worked just fine). After all this hassle I decided to check the partition table "just to be sure"- and the disk utility gives the warning message I described.

• How to enable systemd instantiated service with puppet?

  - by Richard Pena

  I've got the following puppet service: service { "[email protected]": provider => systemd, ensure => running, enable => true, } When I try to apply this configuration on my client, it throws the following error: err: /Stage[main]//Node[puppetclient]/Service[[email protected]]/enable: change from false to true failed: Could not enable [email protected]: The service is running fine and I can make sure it's started on system boot by adding a symlink to getty.target.wants: ln -s /lib/systemd/system/[email protected] /etc/systemd/system/getty.target.wants/[email protected] Of source, I could go ahead and remove "enable = true" from the service definition and include a the symlink manually in the puppet configuration, but shouldn't puppet take care of this? Am I doing something terribly wrong?

• yum-updatesd problem

  - by smusumeche

  I am trying to setup yum-updatesd to send email notification when there are updates available to the packages on my system. However, I am not receiving any notifications even though there are updates available (as seen in yum check-update) I have verified that the yum-updatesd service is running. This is my /etc/yum/yum-updatesd.conf: [main] # how often to check for new updates (in seconds) run_interval = 3600 # how often to allow checking on request (in seconds) updaterefresh = 600 # how to send notifications (valid: dbus, email, syslog) emit_via = email email_to = [email protected] email_from = [email protected] # should we listen via dbus to give out update information/check for # new updates dbus_listener = yes # automatically install updates do_update = no # automatically download updates do_download = no # automatically download deps of updates do_download_deps = no

• How to reset the language of the package descriptions

  - by xubuntix

  I have had German as my main language about a year ago. Later I changed it to English. Most parts of the system accepted the change. The notable exceptions are the package descriptions, which remain in German for some packages. You can see in the image (apt-cache and software-center), that while some descriptions are in English, some have remained in German. So the question is: how do I reset this? I guess that there is somewhere a description cache that needs to be told that it should update all descriptions? EDIT: As asked: the output of some language related commands: $ cat /etc/default/locale LANG="en_US.UTF-8" $ apt-config dump | grep Lang Acquire::Languages ""; Acquire::Languages:: "de_DE"; Acquire::Languages:: "de"; Acquire::Languages:: "en"; Acquire::Languages:: "none"; $ locale LANG=de_DE.UTF-8 LANGUAGE=en LC_CTYPE="de_DE.UTF-8" LC_NUMERIC="de_DE.UTF-8" LC_TIME="de_DE.UTF-8" LC_COLLATE="de_DE.UTF-8" LC_MONETARY="de_DE.UTF-8" LC_MESSAGES="de_DE.UTF-8" LC_PAPER="de_DE.UTF-8" LC_NAME="de_DE.UTF-8" LC_ADDRESS="de_DE.UTF-8" LC_TELEPHONE="de_DE.UTF-8" LC_MEASUREMENT="de_DE.UTF-8" LC_IDENTIFICATION="de_DE.UTF-8" LC_ALL= As a note: I'm not sure what each entry means, but some of the de_DE.UTF-8 are probably ok, since I do want paper-sizes, monetary, time, etc. in standard German formats.

• Is it reasonable to require passwords when users sign into my application through social media accounts?

  - by BrMcMullin

  I've built an application that requires users to authenticate with one or more social media accounts from either Facebook, Twitter, or LinkedIn. Edit Once the user has signed in, an 'identity' for them is maintained in the system, to which all content they create is associated. A user can associate one account from each of the supported providers with this identity. I'm concerned about how to protect potential users from connecting the wrong account to their identity in our application. /Edit There are two main scenarios that could happen: User has multiple accounts on one of the three providers, and is not logged into the one s/he desires. User comes to a public or shared computer, in which the previous user left themselves logged into one of the three providers. While I haven't encountered many examples of this myself, I'm considering requiring users to password authenticate with Facebook, Twitter, and LinkedIn whenever they are signing into our application. Is that a reasonable approach, or are there reasons why many other sites and applications don't challenge users to provide a user name and password when authorizing applications to access their social media accounts? Thanks in advance! Edit A clarification, I'm not intending to store anyone's user name and password. Rather, when a user clicks the button to sign in, with Facebook as an example, I'm considering showing an "Is this you?" type window. The idea is that a user would respond to the challenge by either signing into Facebook on the account fetched from the oauth hash, or would sign into the correct account and the oauth callback would run with the new oauth hash data.

• Set origin for forwarder based on virtual domain in Postfix

  - by Andrew Koester

  I currently have a machine set up to operate with two domains. The main name uses the standard Unix-user delivery, and the second domain is entirely virtual (using virtual_alias_domains and virtual_alias_maps), with the second domain only forwarding mail. However, when mail is forwarded, it still appears to be delivered by the host of the primary domain (presumably set by myorigin.) Is it possible to get it so when mail is forwarded to the virtual domain, it appears to be delivered by it as well? That domain is on another IP and I'd like to use it so the mail stays consistent. Thanks.

• Reclaiming deleted disk space from file vault

  - by cbrulak

  I have my main user account encrypted with file vault. After deleting some data (like 20 GB) my free space on the hard drive hasn't change (yes I emptied the trash, confirmed that the files are actually gone, etc,etc). I also tried "erasing free space" in the disk utility app. I logged off, and rebooted and so far that space hasn't been reclaimed. I'm assuming file vault or disk utility has some method of reclaiming but I can't find it. Any ideas?

• Using .htaccess, can you hide the true URL?

  - by Richard Muthwill

  So I have a web hotel with 1 main website http://www.myrootsite.com/ and a few websites in subdirectories, in a folder called projects. I have domain names pointing to the subdirectories, but when holding the mouse over a link in those websites the URLs are shown as: http://www.myrootsite.com/projects/mysubsite/contact.html When I'm on mysubsite.com I want them to be shown as: http://www.mysubsite.com/contact.html I spoke to support for the web hotel and the guy said try using .htaccess, but I'm not sure exactly how to do this. Thank you very much for your time! Edit: For more information My website is: http://www.example1.com/ and I also own http://www.example2.com/. All of example2.com's files are in: example1.com/projects/example2/. When you visit example2.com, you'll notice all of the URL's point towards: example1.com/projects/example2/ but I want them to point towards: example2.com/ Can this be done? I hope this is enough info for you to go on :). Edit: For w3d I go to the url mysubsite.com and the browser shows the url mysubsite.com. The services I'm using create an iframe around myrootsite.com and use the url mysubsite.com I just hate that in Firefox and Internet Explorer, holding the mouse over link show that the destination url is: myrootsite.com/projects/mysubsite/...

• Is there any way to optimize my search blob program?

  - by Vicky

  I written this code to search the blob items (text files) on the basis of there content. For ex : if I search for "Good", then the files that contains "Good or good" word the name of that files should appear in search result. My code is working but i want to optimize it. class BlobSearch { public static int num = 1; static void Main(string[] args) { string accountName = "accountName"; string accessKey = "accesskey"; string azureConString = "DefaultEndpointsProtocol=https;AccountName=" + accountName + ";AccountKey=" + accessKey; string blob = "MyBlobContainer"; string searchText = string.Empty; Console.WriteLine("Type and enter to search : "); searchText = Console.ReadLine(); CloudStorageAccount account = CloudStorageAccount.Parse(azureConString); CloudBlobClient blobClient = account.CreateCloudBlobClient(); CloudBlobContainer blobContainer = blobClient.GetContainerReference(blob); blobContainer.FetchAttributes(); var blobItemList = blobContainer.ListBlobs(); GetBlobList(searchText, blobContainer, blobItemList); Console.ReadLine(); } private static async void GetBlobList(string searchText, CloudBlobContainer blobContainer, IEnumerable<IListBlobItem> blobItemList) { foreach (var item in blobItemList) { string line = string.Empty; CloudBlockBlob blockBlob = blobContainer.GetBlockBlobReference(item.Uri.ToString()); if (blockBlob.Name.Contains(".txt")) { await Search(searchText, blockBlob); } } } private async static Task Search(string searchText, CloudBlockBlob blockBlob) { string text = await blockBlob.DownloadTextAsync(); if (text.ToLower().IndexOf(searchText.ToLower()) != -1) { Console.WriteLine("Result : " + num + " => " + blockBlob.Name.Substring(blockBlob.Name.LastIndexOf('/') + 1)); num++; } } } I think blobContainer.ListBlobs(); is blocking code because search will not work until all the blob items loaded. Is there anyway to optimize it or anywhere else in my code. Thanks

• nginx: URL rewrites and performance

  - by j0nes

  I have a website where I need to change the URL structure. The old URLs look like /olddir/part1_de.htm, the new ones will look like /newdir/sub/category/anotherpage.htm. There are a lot of URL rewrites I need to do, I assume about 500 distinct rewrites in the end. As my website gets quite a lot of traffic, my main concern is about performance at the moment. My questions are: I assume that for each request, the rewrites block will be parsed and the regex will be evaluated. Am I right? Will there be a performance penalty if I use these rewrites? Can nginx handle this? Are there any "best practices" to follow when doing a lot of rewrites?

• Project Euler Problem 14

  - by MarkPearl

  The Problem The following iterative sequence is defined for the set of positive integers: n n/2 (n is even) n 3n + 1 (n is odd) Using the rule above and starting with 13, we generate the following sequence: 13 40 20 10 5 16 8 4 2 1 It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1. Which starting number, under one million, produces the longest chain? NOTE: Once the chain starts the terms are allowed to go above one million. The Solution   public static long NextResultOdd(long n) { return (3 * n) + 1; } public static long NextResultEven(long n) { return n / 2; } public static long TraverseSequence(long n) { long x = n; long count = 1; while (x > 1) { if (x % 2 == 0) x = NextResultEven(x); else x = NextResultOdd(x); count++; } return count; } static void Main(string[] args) { long largest = 0; long pos = 0; for (long i = 1000000; i > 1; i--) { long temp = TraverseSequence(i); if (temp > largest) { largest = temp; pos = i; } } Console.WriteLine("{0} - {1}", pos, largest); Console.ReadLine(); }

• Is there a way to backup all my files and replace with 0-byte files with same name?

  - by laggingreflex

  My main drive on laptop keeps filling up so I take a backup on a USB and delete the original files. But then I find myself getting (downloading or getting from someone else) files that I already have backed-up but couldn't recall at the moment. So is there a way I can keep a 0-byte file with the same name as teh backed-up copy so that when I'm asked whether to overwrite the existing file, I can easily choose no knowing I probably have this file already in the backup. EDIT: better yet, replace with a shortcut(.lnk) on the external drive so I can access the files hassle free and not get any errors because of 0-byte files being accidentally opened.

• Emulate Historical Figures i.e. Einstein - Is this possible using linguistic logic for my http://www.ustimeline.com Education System

  - by Johnnylight

  After hearing about the success of IBM's Watson I started thinking perhaps emulating human language is now possible? My goal is to create Virtual Historical characters to represent the main characters in my Adventur-Cation The Great American Adventure program such as Einstein or Crazy Horse. The goal is to build an intelligent system capable of indexing the internet and storing the data using a schema using modern knowledge on linguistic theory (phonemes, morphemes, syntax) to build a system capable to returning a semantically sound response very similar to the response made by the same person if still alive today. The goal would be to use the same engine/system for all characters. Each characters would have their own digital representation and voice, and would organize data differently based on tags/keywords stored about the individual. Imagine a Max Headroom Einstein. Based on the success of Watson, I believe something like this may now be possible. Would be an interesting way to study history and would be a vehicle of entertainment as well. Can anyone confirm if this has already been attempted? Is anyone interested in exploring this using Cognitive Science, Psychology, Artificial Intelligence, Historical data captured on the internet, and Linguistic theory?

• Setting up IIS7 to mimic a GoDaddy shared hosting plan

  - by NerdFury

  I host multiple domains on a GoDaddy shared hosting account. I would like to setup a website locally in IIS 7 that mimics the setup of my hosted account so that I can test and debug applications locally before deploying, as debugging after deploying, or discovering there are issues after deploying is frustrating. I have created a folder WebRoot, at put my main application in that folder. I created a website in IIS 7 and pointed it at that folder. I setup bindings with a fake domain, and created a matching entry in my hosts file to make the fake domain point at my 127.0.0.1. I then created a folder www.otherdomain.com under webroot. I then created an application underneath my website, and pointed it at this folder. I can't find how I can add bindings to the web application to have it referenced as a different fake domain, rather than a subdirectory under my root domain. What would be the proper way to setup IIS to best simulate the environment on the GoDaddy servers.

• Multitouch screen not detected on Asus Taichi 21DH71

  - by geekfreak

  I just bought this Ultrabook "Asus Taichi 21 DH71". This has Intel 3rd generation i7 processor and 4gb ram with 256 gb SSD. The main feature is that it is a hybrid machine. Naming it has dual screens. When the lid is closed it can be used as a tablet and when lid open it can be used as a notebook. This machine can also be used with the two screens on at the same time. I used ubuntu many years ago and loved it. But I never tried any linux later. My questions are Does the new version of Ubuntu support the Multitouch interface? Will it work specifically on this machine? Will Ubuntu support gestures on multi touchpad? Update 2/22/2013 I did try the latest 64bit Ubuntu(12.10) from live usb and noticed that it couldn't detect the tablet screen. Everything else worked seamlessly. Do you guys think the tablet screen would be detected if I make a complete installation on to the notebook? Please help guys..

• vim + Ruby on Rails: how do you bounce among those 4-5 files you're currently working on?

  - by glitch

  I'm just starting to get familiar with vim, and I'd like to use it as my primary Rails development tool. As a Visual Studio and RubyMine user, I find a lot of stuff to be missing from the barebones vim installation, and therefore I went ahead and attempted to soup it up with plugins such as: rails.vim tcomment ruby-vim NERDtree and a couple of others. The issue is that I still don't quite get the average work-flow of using vim as one's Rails IDE. In RubyMine (again, similarly to Visual Studio) I have a series of tabs always open, containing the main files I'm switching among, and I additionally use NERDtree to open files from the folder structure. I tried opening them as new tabs, but the tab system in vim is just a lot more awkward than that in real IDEs. (I haven't seen vim pros in action, but I imagine that they'd not be relying on tabs, but using numerous splits instead, keeping at least a couple of files per split and switching between them with CTRL + ^. Is that the case?) So, at the end of the day, how do I really squeeze the most from vim if I want to be able to quickly access several files at once? Thank you!

• Adventures in Lab Management Configuration: CMMI Edition Part 1 of 3

  - by Enrique Lima

  I remember at one point someone telling me how close Migrate was to Migraine. This was a process that included an environment from TFS 2008 to TFS 2010, needed to be migrated too as far as the process template goes.  Here we are talking about CMMI v4.2 to CMMI v5.0.  Now, the process to migrate the TFS Infrastructure is one thing, migrating the Process Template is a different deal, not hard … just involved. Followed a combination of steps that came from a blog post as the main guidance and then MSDN (as suggested on the guidance post) to complement some tasks and steps. Again, the focus I have here is CMMI. The high level steps taken to enable the TFS 2008 CMMI v4.2 migrated to TFS 2010 Process Template are: 1)  Backup the Collection, Configuration and Warehouse Databases. 2)  Downloaded the Process Template using Visual Studio 2010. 3) Exported, modified and imported Bug Type Definition 4) Exported, modified and imported Scenario or Requirement Type Definition. 5) Created and imported bug field mappings. Now, we can attempt to connect using Test Manager, and you should be able to get this going. After that was done, it was time to enroll VMs that already existed in the environment.  This was a bit more challenging, but in the end it was a matter of just analyzing the changes that had been made to had a temporary work around from the time we migrated to the time we converted the Work Items and such and added fields to enable communication between the project and the Test and Lab Manager component. There are 2 more parts to this post, the second will describe the detailed steps taken to complete the Process Template update and the third will talk about the gotchas and fixes for the Lab Management portion.

• How to know how much detailed requirements should be?

  - by user1620696

  This doubt has to do with the requirements gathering phase of each iteration in one project based on agile methodologies. It arose because of the following situation: suppose I meet with my customer to gather the requirements and he says something like: "I need to be able to add, edit, remove and see details of my employees". That's fine, but how should we register this requirement? Should we simply write something like "the system must allow the user to manage employees", or should we be more specific writing for points The system must allow the user to add employees; The system must allow the user to see details of employees; The system must allow the user to edit employees; The system must allow the user to delete employees; Of course, this is just an example of a situation I was in doubt. The main point here is: how to know how much detailed I must be, and how to know what I should register? Are there strategies for dealing with these things? Thanks very much in advance!

• What to learn after standard C++?

  - by Luca Cerone

  I switched to C++ a few months ago, learning its syntax, the main features of the STL and what you can usually find in a "learn C++" manual. Now I would like to go further. What would be your recommendations? I would like to know what to learn next (not only about the language, but also debugging, frameworks etc. etc.) I know probably the answer depends on the specific needs of each user, so here is a list of mine: Cross Platform development Developing GUI for my programs Develop extendible software, allowing the use of plugins Use of scientific libraries Interact with databases (mainly MySQL) Having server/client functionalities (I'd like users of my programs to interact through internet.. as you might have guessed I am not a programmer by training so I might have used the wrong terms.. if so I apologize for that). Of course I know it takes time, but I would like to have a good list of references and resources to start (both books and websites are ok). Thanks a lot for your help!

• How determine keyboard variation when manufacturer changes it

  - by Maksee

  When I decided to purchase Toshiba Z830, I specially noticed at photos that the keyboard was good for me (wide Enter, Left Shift, Backspace), you can query it at images.google.com, on most photos they're all wide. When I finally bought it (Z830-A2S), the keyboard was different, the Enter is narrow and the left Shift is "split" into Shift and backslash keys (probably 5% of photos at images.google.com). Is it normal for manufacturers to change this during the production cycle or this can be variations from different contractors? But the main point, is it possible to determine this from the full model name or somewhere else without visiting a store?

• fresh install of ubuntu 12.04 using usb stick booted into tty1?

  - by croc

  I just installed ubuntu 12.04 alternate for the first time to give it a try using a usb stick burned with UnetBootIn. It installed without a problem. But it booted into a tty1 console without booting into a GUI. after loging into the tty1 console i typed 'unity'. it appeared that the system doesn't have unity desktop !!! How can it be solved ? My installation didn't show any error. Something worth mentioning: 1. during installation i had to choose an option saying 'customize the system to your needs' something like that i don't remember correctly with options 'SSH server','Mail Server', 'Ubuntu Desktop',.....,'Manual selection of packages' etc. I chose 'Ubuntu Desktop'. I haven't encountered something like this in ubuntu 11.04. to do an installation of alternate iso using UnetBootIn i used '12.04_Hdmedia' option of that software and had to change file extension of .ude to .udeb in /pool/main/l/linux that i found in Alternate ubuntu cdrom detect to go around with the cdrom detection problem. I have a 945G intel graphics.

• Recently reloaded computer, now have trailing effect when windows overlap

  - by Tony

  I recently did a clean install of my home machine and I am having a weird graphical error where if I move one window across the top of another it leaves a trail: I have the most recent NVIDIA drivers installed and nothing new is installed on my machine than before the reload (and I never had this issue before). I have two monitors and it happens on both so I'm sure it isn't a hardware issue (the card and my main monitor are also both less than 6 months old) I've also noticed a ripple when scrolling down on web pages which I believe is related. Any ideas what might be causing this and solutions to fix it?

• Checking timeouts made more readable

  - by Markus

  I have several situations where I need to control timeouts in a technical application. Either in a loop or as a simple check. Of course – handling this is really easy, but none of these is looking cute. To clarify, here is some C# (Pseudo) code: private DateTime girlWentIntoBathroom; girlWentIntoBathroom = DateTime.Now; do { // do something } while (girlWentIntoBathroom.AddSeconds(10) > DateTime.Now); or if (girlWentIntoBathroom.AddSeconds(10) > DateTime.Now) MessageBox.Show("Wait a little longer"); else MessageBox.Show("Knock louder"); Now I was inspired by something a saw in Ruby on StackOverflow: Now I’m wondering if this construct can be made more readable using extension methods. My goal is something that can be read like “If girlWentIntoBathroom is more than 10 seconds ago” 1st attempt if (girlWentIntoBathroom > (10).Seconds().Ago()) MessageBox.Show("Wait a little longer"); else MessageBox.Show("Knock louder"); So I wrote an extension for integer that converts the integer into a TimeSpan public static TimeSpan Seconds(this int amount) { return new TimeSpan(0, 0, amount); } After that, I wrote an extension for TimeSpan like this: public static DateTime Ago(this TimeSpan diff) { return DateTime.Now.Add(-diff); } This works fine so far, but has a great disadvantage. The logic is inverted! Since girlWentIntoBathroom is a timestamp in the past, the right side of the equation needs to count backwards: impossible. Just inverting the equation is no solution, because it will invert the read sentence as well. 2nd attempt So I tried something new: if (girlWentIntoBathroom.IsMoreThan(10).SecondsAgo()) MessageBox.Show("Knock louder"); else MessageBox.Show("Wait a little longer"); IsMoreThan() needs to transport the past timestamp as well as the span for the extension SecondsAgo(). It could be: public static DateWithIntegerSpan IsMoreThan(this DateTime baseTime, int span) { return new DateWithIntegerSpan() { Date = baseTime, Span = span }; } Where DateWithIntegerSpan is simply: public class DateWithIntegerSpan { public DateTime Date {get; set;} public int Span { get; set; } } And SecondsAgo() is public static bool SecondsAgo(this DateWithIntegerSpan dateAndSpan) { return dateAndSpan.Date.Add(new TimeSpan(0, 0, dateAndSpan.Span)) < DateTime.Now; } Using this approach, the English sentence matches the expected behavior. But the disadvantage is, that I need a helping class (DateWithIntegerSpan). Has anyone an idea to make checking timeouts look more cute and closer to a readable sentence? Am I a little too insane thinking about something minor like this?

• When decomposing a large function, how can I avoid the complexity from the extra subfunctions?

  - by missingno

  Say I have a large function like the following: function do_lots_of_stuff(){ { //subpart 1 ... } ... { //subpart N ... } } a common pattern is to decompose it into subfunctions function do_lots_of_stuff(){ subpart_1(...) subpart_2(...) ... subpart_N(...) } I usually find that decomposition has two main advantages: The decomposed function becomes much smaller. This can help people read it without getting lost in the details. Parameters have to be explicitly passed to the underlying subfunctions, instead of being implicitly available by just being in scope. This can help readability and modularity in some situations. However, I also find that decomposition has some disadvantages: There are no guarantees that the subfunctions "belong" to do_lots_of_stuff so there is nothing stopping someone from accidentally calling them from a wrong place. A module's complexity grows quadratically with the number of functions we add to it. (There are more possible ways for things to call each other) Therefore: Are there useful convention or coding styles that help me balance the pros and cons of function decomposition or should I just use an editor with code folding and call it a day? EDIT: This problem also applies to functional code (although in a less pressing manner). For example, in a functional setting we would have the subparts be returning values that are combined in the end and the decomposition problem of having lots of subfunctions being able to use each other is still present. We can't always assume that the problem domain will be able to be modeled on just some small simple types with just a few highly orthogonal functions. There will always be complicated algorithms or long lists of business rules that we still want to correctly be able to deal with. function do_lots_of_stuff(){ p1 = subpart_1() p2 = subpart_2() pN = subpart_N() return assembleStuff(p1, p2, ..., pN) }
