  • Can Visual Studio (should it be able to) compute a diff between any two changesets associated with a

    - by Hamish Grubijan
    Here is my use case: I start on a project XYZ, for which I create a work item, and I make frequent check-ins, easily 10-20 in total. ALL of the code changes will be code-read and code-reviewed. The change sets are not consecutive - other people check-in in-between my changes, although they are very unlikely to touch the exact same files. So ... at the en of the project I am interested in a "total diff" - as if there was a single check-in by me to complete the entire project. In theory this is computable. From the list of change sets associated with the work item, you get the list of all files that were affected. Then, the algorithm can aggregate individual diffs over each file and combine them into one. It is possible that a pure total diff is uncomputable due to the fact that someone else renamed files, or changed stuff around very closely, or in the same functions as me. I that case ... I suppose a total diff can include those changes by non-me as well, and warn me about the fact. I would find this very useful, but I do not know how to do t in practice. Can Visual Studio 2008/2010 (and/or TFS server) do it? Are there other source control systems capable of doing this? Thanks.

  • Query total page count via SNMP HP Laserjet

    - by Tim
    I was asked to get hold of the total pages counts for the 100+ printers we have at work. All of them are HP Laser or Business Jets of some description and the vast majority are connected via some form of HP JetDirect network card/switch. After many hours of typing in IP addresses and copying and pasting the relevant figure in to Excel I have now been asked to do this on a weekly basis. This led me to think there must be an easier way, as an IT professional I can surely work out some time saving method to solve this issue. Suffice it to say I do not feel very professional now after a day or so of trying to make SNMP work for me! From what I understand the first thing is to enable SNMP on the printer. Done. Next I would need something to query the SNMP bit. I decided to go open source and free and someone here recommended net-snmp as a decent tool (I would like to have just added the printers as nodes in SolarWinds but we are somewhat tight on licences apparently). Next I need the name of the MIB. For this I believe the HP-LASERJET-COMMON-MIB has the correct information in it. Downloaded this and added to net-snmp. Now I need the OID which I believe after much scouring is printed-media-simplex-count (we have no duplex printers, that we are interested in at least). Running the following command yields the following demoralising output: snmpget -v 2c -c public 10.168.5.1 HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1 (the OID was derived from running: snmptranslate -IR -On printed-media-simplex-count Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt .1.3.6.1.2.1.1.16.1.1.1 ) Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1: Am I barking up the wrong tree completely with this? My aim was to script it all to output to a file for all the IP addresses of the printers and then plonk that in Excel for my lords and masters to digest at their leisure. I have a feeling I am using either the wrong MIB or the wrong OID from said MIB (or both). Does anyone have any pointers on this for me? Or should I give up and go back to navigationg each printers web page individually (hoping not).

  • Ubuntu Newbie Needs Assistance!!

    - by Steve Greene
    New Ubuntu User Needs Help!- version 9.10 does not communicate with laptop Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, even when sitting directly under the wireless router at the local library (literally), which puts out a wickedly-fast signal that my Windows Vista OS auto-detects and immediately connects to. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all, even though I am only a few feet from the router. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I desparately wish to convert to Ubuntu. I used Mac for ten years, and then Windows for ten years. Now, after 20 years, I want to live out my days as an open-source Ubuntu fanatic. I am ready to give the old status quo the boot! I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch so that I can move on in total Ubuntu bliss? My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System. I am running Windows Vista Home Basic, Service Pack 2. My current email is [email protected] if you have a workable solution that does not require programmer status to implement. Surely this must be a simple fix that I simply am overlooking, but being the new guy on the block, I have yet to be enlightened. Thanks for your help in coming up to speed!! Steve Wanna' be Ubuntu Fanatic "If you're not living on the edge, you're taking up too much space."

  • Total row count for pagination using JPA Criteria API

    - by ThinkFloyd
    I am implementing "Advanced Search" kind of functionality for an Entity in my system such that user can search that entity using multiple conditions(eq,ne,gt,lt,like etc) on attributes of this entity. I am using JPA's Criteria API to dynamically generate the Criteria query and then using setFirstResult() & setMaxResults() to support pagination. All was fine till this point but now I want to show total number of results on results grid but I did not see a straight forward way to get total count of Criteria query. This is how my code looks like: CriteriaBuilder builder = em.getCriteriaBuilder(); CriteriaQuery<Brand> cQuery = builder.createQuery(Brand.class); Root<Brand> from = cQuery.from(Brand.class); CriteriaQuery<Brand> select = cQuery.select(from); . . //Created many predicates and added to **Predicate[] pArray** . . select.where(pArray); // Added orderBy clause TypedQuery typedQuery = em.createQuery(select); typedQuery.setFirstResult(startIndex); typedQuery.setMaxResults(pageSize); List resultList = typedQuery.getResultList(); My result set could be big so I don't want to load my entities for count query, so tell me efficient way to get total count like rowCount() method on Criteria (I think its there in Hibernate's Criteria).

  • OpenMP: Get total number of running threads

    - by Konrad Rudolph
    I need to know the total number of threads that my application has spawned via OpenMP. Unfortunately, the omp_get_num_threads() function does not work here since it only yields the number of threads in the current team. However, my code runs recursively (divide and conquer, basically) and I want to spawn new threads as long as there are still idle processors, but no more. Is there a way to get around the limitations of omp_get_num_threads and get the total number of running threads? If more detail is required, consider the following pseudo-code that models my workflow quite closely: function divide_and_conquer(Job job, int total_num_threads): if job.is_leaf(): # Recurrence base case. job.process() return left, right = job.divide() current_num_threads = omp_get_num_threads() if current_num_threads < total_num_threads: # (1) #pragma omp parallel num_threads(2) #pragma omp section divide_and_conquer(left, total_num_threads) #pragma omp section divide_and_conquer(right, total_num_threads) else: divide_and_conquer(left, total_num_threads) divide_and_conquer(right, total_num_threads) job = merge(left, right) If I call this code with a total_num_threads value of 4, the conditional annotated with (1) will always evaluate to true (because each thread team will contain at most two threads) and thus the code will always spawn two new threads, no matter how many threads are already running at a higher level. I am searching for a platform-independent way of determining the total number of threads that are currently running in my application.

  • Adding up row number and displaying total using COUNT (PHP MySQL)

    - by Yvonne
    I'm attempting to run a query that adds up the total number of subjects in a class. A class has many subjects. There is a 'teachersclasses' table between teachers (the user table) and classes. The principles sounds pretty simple but I'm having some trouble in getting my page to display the number of subjects for each class (directly associated with the teacher) This is what I have so far, trying to make use of the COUNT with a nested SELECT: SELECT (SELECT count(*) FROM subjects WHERE subjects.classid = class.classid) AS total_subjects, class.classname, class.classid FROM class Then I am calling up 'num_subjects' to present the total within a while loop: <?php echo $row['total_subjects']?> From the above, I am receiving the total subjects for a class, but within the same table row (for one class) and my other while loop doesnt run anymore, which returns all of the classes associated with a teacher :( ... Bit of a mess now! I know to return the classes for a particular teacher, I can do an additional WHERE clause on the session of 'teacherid' but I think my query is getting too complicated for me that errors are popping up everywhere. Anyone have a quick fix for this! Thanks very much

  • Field to display Previous 30 Day Total

    - by whytheq
    I've got this table: CREATE TABLE #Data1 ( [Market] VARCHAR(100) NOT NULL, [Operator] VARCHAR(100) NOT NULL, [Date] DATETIME NOT NULL, [Measure] VARCHAR(100) NOT NULL, [Amount] NUMERIC(36,10) NOT NULL, --new calculated fields [DailyAvg_30days] NUMERIC(38,6) NULL DEFAULT 0 ) I've populated all the fields apart from DailyAvg_30days. This field needs to show the total for the preceding 30 days e.g. 1. if Date for a particular record is 2nd Dec then it will be the total for the period 3rd Nov - 2nd Dec inclusive. 2. if Date for a particular record is 1st Dec then it will be the total for the period 2nd Nov - 1st Dec inclusive. My attempt to try to find these totals before updating the table is as follows: SELECT a.[Market], a.[Operator], a.[Date], a.[Measure], a.[Amount], [DailyAvg_30days] = SUM(b.[Amount]) FROM #Data1 a INNER JOIN #Data1 b ON a.[Market] = b.[Market] AND a.[Operator] = b.[Operator] AND a.[Measure] = b.[Measure] AND a.[Date] >= b.[Date]-30 AND a.[Date] <= b.[Date] GROUP BY a.[Market], a.[Operator], a.[Date], a.[Measure], a.[Amount] ORDER BY 1,2,4,3 Is this a valid approach or do I need to approach this from a different angle?

  • Terminology for web app running on hardware

    - by Lily
    Hi, Let me start by saying I feel very silly asking this, hence the newbie tag. I am trying to investigate how to develop an UI application that will run directly on hardware. This will be very much like when you access the web based application within your router. I don't really know how what keywords and terminology to use so that i can search tutorials on the net. Can anybody give me the correct terms? If you have tutorial suggestions, they are welcome as well.

  • Using Protocol Buffers in J2EE?

    - by mlaverd
    Hello everyone, I have coded a server that uses Protocol Buffers in Java. A client talks to it using PB. I'd like to migrate the server code to J2EE and take advantage of the containers' built-in features like clustering. How can I have a service that receives PB messages and interprets them properly, and then gets them handled? I was thinking of a dedicated type of servlet, but how can it be done? I'm a J2EE newbie... I'm not familiar enough with J2EE application servers to know if there is a way to make that happen. P.S. I'm looking for a solution that uses TLS sockets directly. No overhead-causing middleman protocols like HTTP are welcome here. P.P.S. Open source solutions only please.

  • RoR associations through or not through?

    - by showFocus
    I have four models that are related to one another, the way I have it setup at the moment is I have to select a county, region and country when entering a new city. class Country < ActiveRecord::Base has_many :regions has_many :counties has_many :cities end class Region < ActiveRecord::Base has_one :country has_many :counties has_many :cities end class County < ActiveRecord::Base has_one :country has_one :region has_many :cities end class City < ActiveRecord::Base has_one :country has_one :region has_one :county end Would it be better to use the :through symbol in the association? So I could say the city: has_one :country, :through => :region Not sure if this is correct, I have read how :through works but I'm not sure if this is the best solution. I am a newbie and while I'm not struggling with the syntax and how things work, it would be good to get opinions on best practices and the way things should be done from some rails wizards! Thanks in advance.

  • PHP/Mysql issues

    Php/my sql newbie question. I have a database I've imported into my local phpmyadmin. However it seems I can't access it from my a php application. The connection string seems right and when i try to authenticate user credentials to access database information, no problems. However authenticate everyone and knows when i put in fake credentials. Still it won't pull any other information from the database. For instance, once a users login they should see something like, "Hello username"... that kind of thing. At this point I see "Hello" without the username. Any ideas what i might be missing?

  • Avoid loading unnecessary data from db into objects (web pages)

    - by GmGr
    Really newbie question coming up. Is there a standard (or good) way to deal with not needing all of the information that a database table contains loaded into every associated object. I'm thinking in the context of web pages where you're only going to use the objects to build a single page rather than an application with longer lived objects. For example, lets say you have an Article table containing id, title, author, date, summary and fullContents fields. You don't need the fullContents to be loaded into the associated objects if you're just showing a page containing a list of articles with their summaries. On the other hand if you're displaying a specific article you might want every field loaded for that one article and maybe just the titles for the other articles (e.g. for display in a recent articles sidebar). Some techniques I can think of: Don't worry about it, just load everything from the database every time. Have several different, possibly inherited, classes for each table and create the appropriate one for the situation (e.g. SummaryArticle, FullArticle). Use one class but set unused properties to null at creation if that field is not needed and be careful. Give the objects access to the database so they can load some fields on demand. Something else? All of the above seem to have fairly major disadvantages. I'm fairly new to programming, very new to OOP and totally new to databases so I might be completely missing the obvious answer here. :)

  • Sqlite: Selecting records spread over total records

    - by Martin
    I have a sql / sqlite question. I need to write a query that select some values from a sqlite database table. I always want the maximal returned records to be 20. If the total selected records are more than 20 I need to select 20 records that are spread over the total records. It is also important that I always select the first and last value from the table when sorted on the date. I know how to accomplish this in code but it would be perfect to have a sqlite query that can do the same. The query Im using now is really simple and looks like this: "SELECT value,date,valueid FROM tblvalue WHERE tblvalue.deleted=0 ORDER BY DATE(date)" Hope I explained what I need, thanks for your help!

  • Crystal Reports: global variable running total not displaying in header

    - by phill
    Using Crystal Reports I'm trying to display the running total of a database field in the header where all the labels are. I've attempted to do this by placing the running total (RTversion) into a formula field with the following: Shared stringvar CurrentVers; CurrentVers := {#CurrentVers}; and then in the page header section I have the following: Shared stringvar CurrentVers; EvaluateAFter({#currentVers}); CurrentVers; with {#CurrentVers} running the 1st largest number. Is this incorrect? Update: The goal is to display the latest version in the header near the labels to show what the current verseion is for comparison.

  • Portable way of finding total disk size in Java (pre java 6)

    - by Wouter Lievens
    I need to find the total size of a drive in Java 5 (or 1.5, whatever). I know that Java 6 has a new method in java.io.File, but I need it to work in Java 5. Apache Commons IO has org.apache.commons.io.FileSystemUtils to provide the free disk space, but not the total disk space. I realize this is OS dependant and will need to depend on messy command line invocation. I'm fine with it working on "most" systems, i.e. windows/linux/macosx. Preferably I'd like to use an existing library rather than write my own variants. Any thoughts? Thanks.
