• check two conditions in two different columns in excel and count the matches

  - by user1727103

  I've trying to create a Error Log to help me analyse my mistakes. So for simplicity, lets assume I have two columns "Type of Question" - with values SC,RC,CR and another column that indicates whether I got this question "right/wrong".Let's assume this is my table: Question No. | Right/Wrong | Question Type | Right | SC | Right | RC | Wrong | SC | Wrong | CR | Right | RC (Pardon my formatting skills). And I want an output table like this Type of Question | Right | Wrong | Total SC | 1 | 1 | 2 RC | 2 | 0 | 2 CR | 0 | 1 | 1 So basically what I want to do is check Column3 for SC using =COUNTIF(C1:C5,"SC"), and return the total number of SC questions, and then outta the SC , I need to find out which are Right.If I know the right and the total I can get the wrong. I have never written a macro so a formula based answer would suffice.

• Should i worry about company's Reputation before joining it...

  - by Shekhar_Pro

  My question is particularly in context of this Question asked recently on this site. I am a fresh graduate and would soon be applying for jobs. But the above mentioned question has raised concerns for me. Should i care about the company i am going to join. Specially since for me Yahoo is a very reputed corporation and i duly respect it, in fact i would be proud to work for it if given the chance. And the OP of the question was a Senior Software Engineer, i don't think something could have gone so wrong that he feels shame for have worked there. Well i won't like to have this situation in my career. Until now for me the criteria for approaching a company were like - it should have Good, knowledgeable and Experienced team, it should provide me with tasks that will always challenge me to think and learn more, etc. After all a task is task and you do always learn something from it. But in view of mentioned question should i also consider other things... Please give your answers and most importantly an opinion from your own experience.

• database independent coding framework options?

  - by statirasystems

  Background: I have not programmed in a while besides doing VBA and a little VB.NET. So please forgive my language use. I'm green and have a head cold. I am reading all I can now, but I have no programming circles to draw from. The information I am providing is to help guide you to what I am looking for. I am not confident I can ask the question properly. Story: I have four different projects that I am starting. Obviously I won't be working on all at the same time however they each will have similar needs and be inter related. They are as follows: Desktop Environment/System User Interface - basically a product that runs on major computers via mono or .net that unifies the look and functions. In the context of the up coming question it would be able to directly access data of various types. It would work in tandum with my office suite, system manager, and network application framework. Office Suite - technically it would not be a suite since I will be doing it from one interfacel except for the Communications Application. As far as the question, it will need to be able to link to various data sources for storing files and using, manipulating, and presenting information. System Manager - an intellegent system to manage and administer the entire network and all equipment. As far as the question, needs to be able to access data for archiving and and for accessing it's own settings stored in various formats, sql or xml. Network Application Framework - A complete system that can be used for ERP, CRM, CMS, Errata, File Management, and so on. As to the question to be able to access it's own or interlink with existing applications. Requirement: C#, Simplifies and reduces coding, use the same code to access diffent databases(ie MySQL, MS SQL, ACCESS, XML, ...), Mono would be nice but not a must, Question: What librarys, frameworks, or other options would be able to help with this? Is there a good resource to guide me? I don't want arguing over what is best, just information to help me further understand and make an educated decision.

• What are the reasons to use dos batch programs in Windows?

  - by DVK

  Question What would be a good (ideally, technical) reason to ever program some non-trivial task in dos batch language on a modern Windows system as opposed to downloading either PowerShell, or ActiveState Perl? To be more specific, I make the following two assumptions for the duration of this question: anyone technical enough to be able to write a medium-complexity batch script is technical enough to install either of the scripting interpreters. Neither of those two present enough of a learning curve for basic batch replacement tasks that said curve would outweigh the pain of doing any remotely-non-trivial task in batch. Notes "You need a batch program for autoexec.bat" is not a valid reason. Your autoexec.bat may consist of simply calling non-batch script. If you disagree with either of my 2 assumptions above, that's fine, and I may be wrong. But my question is specifically "assuming those 2 assumptions are correct, what would be the reason to still stick with batch?" If it makes it easier to suspend disbelief (in case you disagree with me), add in a 3rd assumption that the question is limited to people who already posess at least some modicum of PowerShell or Perl experience. To re-iterate - this is not meant to be a subjective question about how easy it is to learn PSh or ASPerl compared to doing advanced batch coding. That is a separate question that is too subjective to be bothered with in this post. Background: I used to do some fairly complicated batch programming back in the elder days, and remember batch as one of the worst possble programming languages I had encountered. The idea for this question came after seeing a bunch of batch questions on SO, and trying to grok the answer of one of them out of sheer curiosity and giving up in pain after a minute, exclaiming mentally "why would anyone go through this pain instead of doing that in 1 line of Perl?" :) My own plausible answer I assume there may be an an likely DOS-compatible system, which has DOS interpreter but has no compatible PowerShell or Perl... I'm not aware of one but not completely impossible.

• Android - updating a list adapter creates a NullPointException

  - by GeekedOut

  I have a ListActivity which has an adapter that crashes. Here is the code that crashes the program: Question q = new Question (); q.setQuestion( "" ); questions.add(q); adapter = new ArrayAdapter<Question>(this, R.layout.user_question_list, R.id.label, questions); Here is how I create the adapter: ArrayAdapter<Question> adapter; ArrayList<Question> questions = new ArrayList <Question>( ); and the list xml is like this: <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textSize="16sp" > </TextView> and the overall Activity xml is like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" > <TextView android:id="@+id/question_label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Loading your questions..." /> <ListView android:id="@android:id/list" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@+id/label" android:textSize="20px" > </ListView> <Button android:id="@+id/add_question" android:layout_height="wrap_content" android:text="Ask a Question" android:onClick="sendFeedback" android:layout_width="fill_parent"> </Button> </LinearLayout> Any idea why the code where I try to update the adapter results in the NullPointerException?

• Ruby custom class to and from YAML;

  - by Sanarothe

  Hi. I'm having trouble deserializing a ruby class that I wrote to YAML. Where I want to be I want to be able to pass one object around as a full 'question' which includes the question text, some possible answers (For multi. choice) and the correct answer. One module (The encoder) takes input, builds a 'question' class out of it and appends it to the question pool. Another module reads a question pool and builds an array of 'question' objects. Where I am currently Sample Question Pool --- | --- !ruby/object:MultiQ a: "no" answer: "no" b: "no" c: "no" d: "no" text: "yes?" Encoder dump to YAML file. Object is a MultiQ filled up with input. (See below.) def dump(file, object) File.open(file, 'a') do |out| YAML.dump(object.to_yaml, out) end object = nil end MultiQ Class definition class MultiQ attr_accessor :text, :answer, :a, :b, :c, :d def initialize(text, answer, a, b, c, d) @text = text @answer = answer @a = a @b = b @c = c @d = d end end The decoder (I've been trying different things, so what's here wasn't my first or best guess. But I'm at a loss and the documentation doesn't really explain things thoroughly enough.) File.open( "test_set.yaml" ) do |yf| YAML.load_documents( yf ) { |item| new = YAML.object_maker( MultiQ, item) puts new } end Questions you can answer How do I achieve my goal? What methods should I use, between parsing, loading files or documents, to successfully deserialize a Ruby class? I've already looked over the YAML Rdoc, and I didn't absorb very much, so please don't just link me to it. What other methods would you suggest using? Is there a better way to store questions like this? Should I be using document db, relational db, xml? Some other format?

• Html.RadioButton group defaulting to 0

  - by awrigley

  Hi A default value of 0 is creeping into a Surveys app I am developing, for no reason that I can see. The problem is as follows: I have a group of Html.RadioButtons that represent the possible values a user can choose to answer a survey question (1 == Not at all, 2 == A little, 3 == A lot). I have used a tinyint datatype, that does not allow null, to store the answer to each question. The view code looks like this: <ol class="SurveyQuestions"> <% foreach (SurveyQuestion question in Model.Questions) { string col = question.QuestionColumn; %> <li><%=question.QuestionText%> <ul style="float:right;" class="MultiChoice"> <li><%= Html.RadioButton(col, "1")%></li> <li><%= Html.RadioButton(col, "2")%></li> <li><%= Html.RadioButton(col, "3")%></li> </ul> <%= Html.ValidationMessage(col, "*") %> </li> <% } %> </ol> [Note on the above code:] Each survey has about 70 questions, so I have put the questions text in one table, and store the results in a different table. I have put the Questions into my form view model (hence Model.Questions); the questions table has a field called QuestionColumn that allows me to link up the answer table column to the question, as shown above (<%= Html.RadioButton(col, "1")%, etc) [/Note] However, when the user DOESN'T answer the question, the value 0 is getting inserted into the database column. As a result, I don't get what I expect, ie, a validation error. In no place have I stipulated a default value of 0 for the fields in the answers table. So what is happening? Any ideas?

• Understanding REST: is GET fundamentally incompatible with any "number of views" counter?

  - by cocotwo

  I'm trying to understand REST. Under REST a GET must not trigger something transactional on the server (this is a definition everybody agrees upon, it is fundamental to REST). So imagine you've got a website like stackoverflow.com (I say like so if I got the underlying details of SO wrong it doesn't change anything to my question), where everytime someone reads a question, using a GET, there's also some display showing "This question has been read 256 times". Now someone else reads that question. The counter now is at 257. The GET is transactional because the number of views got incremented and is now incremented again. The "number of views" is incremented in the DB, there's no arguing about that (for example on SO the number of time any question has been viewed is always displayed). So, is a REST GET fundamentally incompatible with any kind of "number of views" like functionality in a website? So should it want to be "RESTFUL", should the SO main page either stop display plain HTML links that are accessed using GETs or stop displaying the "this question has been viewed x times"? Because incrementing a counter in a DB is transactional and hence "unrestful"? EDIT just so that people Googling this can get some pointers: From http://www.xfront.com/REST-Web-Services.html : 4. All resources accessible via HTTP GET should be side-effect free. That is, the request should just return a representation of the resource. Invoking the resource should not result in modifying the resource. Now to me if the representation contains the "number of views", it is part of the resource [and in SO the "number of views" a question has is a very important information] and accessing it definitely modifies the resource. This is in sharp contrast with, say, a true RESTFUL HTTP GET like the one you can make on an Amazon S3 resource, where your GET is guaranteed not to modify the resource you get back. But then I'm still very confused.

• Execute a block of database querys

  - by Nightmare

  I have the following task to complete: In my program a have a block of database querys or questions. I want to execute these questions and wait for the result of all questions or catch an error if one question fails! My Question object looks like this (simplified): public class DbQuestion(String sql) { [...] } [...] //The answer is just a holder for custom data... public void SetAnswer(DbAnswer answer) { //Store the answer in the question and fire a event to the listeners this.OnAnswered(EventArgs.Empty); } [...] public void SetError() { //Signal an Error in this query! this.OnError(EventArgs.Empty); } So every question fired to the database has a listener that waits for the parsed result. Now I want to fire some questions asynchronous to the database (max. 5 or so) and fire an event with the data from all questions or an error if only one question throws one! Which is the best or a good way to accomplish this task? Can I really execute more then one question parallel and stop all my work when one question throws an error? I think I need some inspiration on this... Just a note: I´m working with .NET framework 2.0

• Design pattern for parsing data that will be grouped to two different ways and flipped

  - by lewisblackfan

  I'm looking for an easily maintainable and extendable design model for a script to parse an excel workbook into two separate workbooks after pulling data from other locations like the command line, and a database. The high level details are as follows. I need to parse an excel workbook containing a sheet that lists unique question names, the only reliable information that can be parsed from the question name is the book code that identifies the title and edition of the textbook the question is associated with, the rest of the question name is not standardized well enough to be reliably parsed by computer. The general form of the question name is best described by the following regular expression. '^(\w+)\s(\w{1,2})\.(\w{1,2})\.(\w{1,3})\.(\w{1,3}\.)*$' The first sub-pattern is the book code, the second sub-pattern is 90% of the time the chapter, and the rest of the sub-patterns could be section, problem type, problem number, or question type information. There is no simple logic, at least not one I can find. There will be a minimum of three other columns in this spreadsheet; one column will be the chapter the question is associated with, the second will be the section within the chapter the question is associated with, and the third will be some kind of asset indicated by a uniform resource locator. 1 | 1 | qname1 | url | description | url | description ... 1 | 1 | qname2 | url | description 1 | 1 | qname3 | url | description | url | description | url | The asset can be indicated by a full or partial uniform resource locator, the partial url will need to be completed before it can be fed into the application. There theoretically could be no limit to the number of asset columns, the assets will be grouped in columns by type. Some times additional data will have to be retrieved from a database or combined with the book code before the asset url is complete and can be understood by the application that will be using the asset. The type is an abstraction, there are eight types right now, each with their own logic in how the uniform resource locator is handled and or completed, and I have to add a new type and its logic every three or four months. For each asset url there is the possibility of a description column, a character string for display in the application, but not always. (I've already worked out validating the description text, and squashing MSs obscure code page down to something 7-bit ascii can handle.) Now that all the details are filled-in I can get to the actual problem of parsing the file. I need to split the information in this excel workbook into two separate workbooks. The first workbook will group all the questions by section in rows. With the first cell being the section doublet and the rest of the cells in the row are the question names. 1.1 | qname1 | qname2 | qname3 | qname4 | 1.2 | qname1 | qname2 | qname3 | 1.3 | qname1 | qname2 | qname3 | qname4 | qname5 There is no set number of questions for each section as you can see from the above example. The second workbook is more complicated, there is one row per asset, and question names that have more than one asset will be duplicated. There will be four or five columns on this sheet. The first is the question name for the asset, the second is a media type used to select the correct icon for the asset in the application, the third is string representing the asset type, the four is the full and complete uniform resource locator for the asset, and the fifth columns is the optional text description for the asset. q1 | mtype1 | atype1 | url | description q1 | mtype2 | atype2 | url | description q1 | mtype2 | atype3 | url | description q2 | mtype1 | atype1 | url | description q2 | mtype2 | atype3 | url | description For the original six types I did have a script that parsed the source excel workbook into the other two excel workbooks, and I was able to add two more types until I ran aground on the implementation of the ninth type and tenth types. What broke my script was the fact that the ninth type is actually a sub-type of one of the original six, but with entirely different logic, and my mostly procedural script could not accommodate without duplicating a lot of code. I also had a lot of bugs in the script and will be writing the test first on this time around. I'm stuck with the format for the resulting two workbooks, this script is glue code, development went ahead with the project without bothering to get a complete spec from the sponsor. I work for the same company as the developers but in the editorial department, editorial is co-sponsor of the project, and am expected to fix pesky details like this (I'm foaming at the mouth as I type this). I've tried factories, I've tried different object models, but each resulting workbook is so different when I find a design that works for generating one workbook the code is not really usable for generating the other. What I would really like are ideas about a maintainable and extensible design for parsing the source workbook into both workbooks with maximum code reuse, and or sympathy.

• NVidia ION and /dev/mapper/nvidia_... issues.

  - by Ritsaert Hornstra

  I have an NVidia ION board with 4 SATA ports and want to use that to run a Linux Server (CentOS 5.4). I first hooed up 3 HDs (that will be a RAID5 array) and a forth small boot HD. I first started to use the onboard RAID capability but that does not work correctly under Linux: the raid capacity is not a real RAID but uses lvm to define some arays. After setting the BIOS back to normal SATA mode and whiping the HDs, the first boot harddisk (/dev/sda) is seen as /dev/sda BEFORE mounting and after mounting as /dev/mapper/nvidia_. CentOS is unable to install on it (and grub is not installable on it either). So somehow the harddisk is still seen as if it belongs to some lvm volume. I tried to clean out the HD by issuing a few dd if=/dev/zero of=/dev/sda commands to wipe the starting cylinders and final cylinders but to no avail. Did anyone see this problem and did anyone find a solution? UPDATE When I create only a single ext3 partition on the first HD (/dev/mapper/nvidia_...) no LVM partitions are seen and I can boot from /dev/mapper/nvidia_.... Now the next step is to see how I can get rid of this folly.

• Mirror a RAID0 volume

  - by Ghostrider

  I have two SSD running in RAID0. The capacity and speed are just great. I use Windows Home Server to do incremental daily backups. This is fine and well and I've successfully restored from these backups. However. When one of the disks physically died. I was stuck without a working system until the replacement arrives so that I can restore the array from backup. WHS restoration takes about 5 hours which basically means that I'm losing entire day for the process. Is it possible to set up kind of a recovery volume for the RAID array? Use a single mechanical HDD that would be updated with the exact clone of the RAID array on a daily basis. This way if the array goes offline for some reason, I can just boot from the mechanical HDD, lose some perf but will still be able to work. The machine in question runs Windows 7. Creating RAID01 is not an option because of the high price of the SSD and the fact that it still doesn't protect against failure of RAID controller. Is there any way it can be set up?

• btrfs: can i create a btrfs file system with data as jbod and metadata mirrored

  - by Yogi

  I am trying to build a home server that will be my NAS/Media server as well a the XBMC front end. I am planning on using Ubuntu with btrfs for the NAS part of it. The current setup consists of 1TB hdd for the OS etc and two 2TB hdd's for data. I plan to have the 2TB hdd's used as JBOD btrfs system in which i can add hdd's as needed later, basically growing the filesystem online. They way I had setup the file system for testing was while installing the OS just have one of the HDD's connected and have btrfs on it mounted as /data. Later on add another hdd to this file system. When the second disk was added btrfs made as RAID 0, with metadata being RAID 1. However, this presents a problem: even if one of the disk fails I loose all my data (mostly media). Also most of the time the server will be running without doing any disk access, i.e. the HDD's can be spun down, when a access request comes in this with the current RAID 0 setup both disks will spin up. in case I manage a JBOD only the disk that has the file needs to be spun up. This should hopefully reduce the MTBF for each disk. So, is there a way in which I can have btrfs setup such that metadata is mirrored but data stays in a JBOD formation? Another question I have is this, I understand that a full drive failure in JBOD will lose data on the drive, but having metadeta mirrored across all drives, will this help the filesytem correct errors that migh creep in (ex bit rot?) and is btrfs capable of doing this.

• restoring a failed SBS 2000 box...

  - by Brad Pears

  Hi there, I read a post where you had mentioned you have had a PERC card blow up on you in an SBS box... I've got a similar situation where one of my RAID drives failed and then the power supply failed before I could replace the drive... I then replaced the power supply and the failed drive and reconfigured the RAID array. I had a recent full backup of the my Win2k SBS's C: drive stored on my SYmantec backup exec server so I installed win2K server on the c: partition and then once I had that up and running, installed the backup exec agent so as to do a restore of the entire c drive including system state. THis all worked just fine, until I had to reboot. I received an "incorrect drive configuration" error and then it hangs. I figure that likely makes sense becasue I think my RAID array is configured slightly different now in that the partitions may be sizeded ever so slightly differently now than they were before I think... Is there a way I can just restore from my backup BUT maybe exclude some of the registry and hidden boot files it wants to restore so that it is booting with the current configuration now active on that machine - not the pre blow up configuration files? I also read a post that indicated you might have to install the exact same service pack etc... etc.. before attemting a restore but that does not make sense to me being as the entire c drive contents are going to be overwritten by the restore anyway? THe basic OS install is just to be able to get the backup exec agent installed . I can;t understand why one would need to install the exact same SP level. CAn you shed some light on what I might be able to do to get this thing up and running? Thanks,Brad

• Disk IO slow on ESXi, even slower on a VM (freeNAS + iSCSI)

  - by varesa

  I have a server with ESXi 5 and iSCSI attached network storage(4x1Tb Raid-Z on freenas 8.0.4). Those two machines are connected to each other with Gigabit ethernet. The raid-z volume is divided into three parts: two zvols, shared with iscsi, and one directly on top of zfs, shared with nfs and similar. I ssh'd into the freeNAS box, and did some testing on the disks. I used ddto test the third part of the disks (straight on top of ZFS). I copied a 4GB (2x the amount of RAM) block from /dev/zero to the disk, and the speed was 80MB/s. Other of the iSCSI shared zvols is a datastore for the ESXi. I did similar test with time dd .. there. Since the dd there did not give the speed, I divided the amount of data transfered by the time show by time. The result was around 30-40 MB/s. Thats about half of the speed from the freeNAS host! Then I tested the IO on a VM running on the same ESXi host. The VM was a light CentOS 6.0 machine, which was not really doing anything else at that time. There were no other VMs running on the server at the time, and the other two "parts" of the disk array were not used. A similar dd test gave me result of about 15-20 MB/s. That is again about half of the result on a lower level! Of course the is some overhead in raid-z - zfs - zvolume - iSCSI - VMFS - VM, but I don't expect it to be that big. I belive there must be something wrong in my system. I have heard about bad performance of freeNAS's iSCSI, is that it? I have not managed to get any other "big" SAN OS to run on the box (NexentaSTOR, openfiler). Can you see any obvious problems with my setup?

• Copying a list in Microsoft word

  - by TaoistWA

  I have a list that looks like this ( notice the list is of the pattern A, B, C etc..) 1. [Insert question 1] A. [Insert response A] B. [Insert response B] C. [Insert response C] D. [Insert response D] 2. [Insert question 2] A. [Insert response A] B. [Insert response B] C. [Insert response C] D. [Insert response D] When I copy and paste it I want it to look exactly the same. However this does not happen. What I get instead is ( the A,B,C, pattern continues on with the rest of the alphabet) 1. [Insert question 1] A. [Insert response A] B. [Insert response B] C. [Insert response C] D. [Insert response D] 2. [Insert question 2] A. [Insert response A] B. [Insert response B] C. [Insert response C] D. [Insert response D] 3. [Insert question 1] E. [Insert response A] F. [Insert response B] G. [Insert response C] H. [Insert response D] 4. [Insert question 2] I. [Insert response A] J. [Insert response B] K. [Insert response C] How do I fix this?

• Keep Windows Installer from using largest drive for temporary files

  - by stefan.at.wpf

  By default Windows Installer uses the largest drive for temporary storage, no matter if that's needed (meaning there would also be enough space on the system drive). Taken from http://msdn.microsoft.com/en-us/library/aa371372%28VS.85%29.aspx: During an administrative installation the installer sets ROOTDRIVE to the first connected network drive it finds that can be written to. If it is not an administrative installation, or if the installer can find no network drives, the installer sets ROOTDRIVE to the local drive that can be written to having the most free space. Now my system drive is an SSD, my largest drive is a RAID, that spins down when it's not used. Remember the SSD as system drive? Everything is silent now! Until I install something and Windows Installer wakes up my RAID again just to put a small .tmp file on it... How can I prevent Windows Installer from using the largest drive as temporary storage? Can I maybe set some access rights to disallow the Windows Installer to write on my RAID drive? Any other ideas? Thank you!

• Dell OpenManage On Ubuntu Server 12.04 Cannot Log In

  - by Austin

  I have a Dell Poweredge 2950 with 2X130GB and 2X2TB drives. I need to set them up in a RAID 1 array so that the 130GB Drives are mirrored and host the OS, while the 2TB drives are mirrored and are the content drives. So I go from 4 disks, down to two, one 130GB and one 2TB. I can do that in the BIOS RAID utility no problem. But I need to be able to manage the RAID arrays and be able to expand them WITHOUT shutting down the server. Now, to my understanding, openmanage will allow me to do that AND it runs on ubuntu. So I go and set it up and try to log into the web interface at and it will not let me log in. I have followed dell's guide to set up openmanage, even added the usernames to the files and permissions and such, however, cannot get it to let me log in or anything. I have reinstalled Openmanage several times, even reinstalled the OS three times, and nothing works. Google does not help either. It simply says login failed after hitting submit. Please Help
