  • Excel: What formula combines this data into one COUNT amount?

    - by Mike
    I have 30 colleagues who are answering questions over 3 time periods. Each has their own Excel workbook with the questions, and over the year they update it. I collate their worksheets into one master worksheet, but now need to combine their answers into a simple table. The questions, the time periods and then a COUNT of how many answered it. For example: I need a table that shows me how many people (not the persons name at this point) answered question 10 in time period 2. I can't use a database before someone mentions it ;). Many thanks Mike.

  • Fedora Core 11 won't boot without a monitor

    - by feihtthief
    I have a P4 system that I installed Fedora 11 on. It will not boot without a monitor attached. The monitor can be off (not even have power plugged in), but must be attached. Without a monitor the hard disk thrashes around a bit like it's starting up services, but does not get to the point where I can ssh into the box. I have set the default runlevel to 3 and removed the rhgb entry from grub. Any suggestions welcome. Edit: I have already set the run-level to 3. The machine boots up fine with the monitor plugged in to the point where I can SSH into it. as soon as i unplug the monitor and reboot, it will not boot to that point.

  • What happens when you add a Graphics card to a i7 with build in graphics (e.g. HD 4000)

    - by Matt
    I'm thinking of upgrading my computer from an AMD Phenom II X4 955BE with a AMD Radeon HD 6800 Graphics card (not integrated) to using a Intel Core i7 3770. As I have no knowledge of integrated graphics, my question is, what happens to the computing power when not using the HD4000 integrated graphics of the CPU (does it mean the CPU will run faster then it would if I relied on it?) Also what is better the CPUs inbuilt HD4000 or my Radeon Graphics card? I am mostly interested in terms of content creation: Using Adobe After Effects, 3D Rendering etc. Not too bothered about gaming performance. I will be using the spare parts of this build and older systems to make a second computer for network renders so what will be the advantages of keeping the Radeon with the current system for that?

  • Computer won't reboot without waiting for a while

    - by Benjamin
    I've got an unusual problem with my computer. When ever I reboot my computer it won't boot, I get a few beeps from the BIOS and nothing else, however if I wait for a few minuets the computer will boot perfectly. I tried to count the beeps and I get around 7-9 of them; the first two are noticeably closer together than the rest. [Edit: I'm now reasonably confident it's 1 long followed by 8 short beeps.

  • Why do some software not get load balanced even when there are multiple cores?

    - by Nav
    While VTune Analyzer was running on a blade server with 8 cores, I observed the cpu useage percentage using mpstat -P ALL 1. mpstat showed me that VTune was taking up 100% of a single core, while all other cores were idle. Why does that happen? Shouldn't the OS (RHEL Server 5.2) automatically distribute load across cores? The same happened when I tried running MATLAB (even after enabling multithreading support in the MATLAB settings). p.s: I'm a developer. Not a sys admin. So felt it better to ask here rather than at serverfault.

  • How can I get a list of default documents in IIS using PowerShell?

    - by SGarratt
    I'm managing a Server Core machine and trying to do everything in PowerShell, which is fun. I need a list of the default documents. From other websites, I've found out how to set and remove them, using both xxx-WebConfiguration and xxx-WebConfigurationProperty. I've tried: Get-WebConfigurationProperty -Filter /system.webServer/defaultDocument -PSPath "IIS:\sites\Default Web Site" -Name files but it gives: Collection : {Microsoft.IIs.PowerShell.Framework.ConfigurationElement, Microsoft.IIs.PowerShell.Framework.Configuration Element, Microsoft.IIs.PowerShell.Framework.ConfigurationElement, Microsoft.IIs.PowerShell.Framework.Confi gurationElement...} ItemXPath : /system.webServer/defaultDocument Attributes : {} ChildElements : {} ElementTagName : files Methods : Schema : Microsoft.IIs.PowerShell.Framework.ConfigurationElementSchema which doesn't really help.

  • Is there a way to rsync in batches?

    - by Chris
    I have a huge chunk of data (11G) in a subversion repository that I'm using rsync to migrate to Alfresco, which lucene indexes new files as they hit the file system. I'm using a dav mount as a proxy to allow me to rsync. The issue I'm having is the indexing post-rsync is quite an expensive operation for such a huge chunk of data, so I was wondering whether there's a way I could logically separate the rsync into identically-sized batches (say 500MB each) so I could schedule them in cron. At the moment, I'm traversing the top level folders and taking the smallest ones across first, but once I'm done with those, the much larger sub-directories are going to be quite troublesome. Please let me know if you need any further info. Thanks in advance.

  • Installing Fedora Core 12 on a VPS

    - by cinqoTimo
    I'm working on a Linux VPS that is running FC6, and I want to reinstall with the latest version FC12. The VPS is running on the Virtuozzo platform. I am also running Plesk on the VPS. This is all managed hosting through Network Solutions, so I don't have access to the actual box. My question is, how does one reinstall a different OS through Virtuozzo? I see "reinstall VPS" in virtuozzo, but this just burns a fresh copy of FC6? Is this a host-by-host thing, or are there best practices for accomplishing this..?

  • Does Intel Smart Response provide any statistics on the cache usage?

    - by Tom Seddon
    I've set up my Z68-based Core i7 PC with a 60GB SSD dedicated as a Smart Response cache drive. Is there any way I can get any statistics out of it? It would be nice to have some information on how much cache space is actually being used, maybe how much of it was actually accessed recently, and how many reads in general are coming from the SSD rather than from the mechanical disk. These statistics might help to quickly provide some evidence for or against the use of Smart Response, without my having to reinstall Windows on the SSD (etc.) to find out. The Windows ReadyBoost feature has some performance counters you can access via the Windows 7 perfmon tool, for example, which is the kind of thing I'm hoping is somehow available. Smart Response provides no perfmon counters, though, and the Intel Rapid Storage Utility tells you pretty much nothing except that Smart Response is switched on.

  • How to store data on a machine whose power gets cut at random

    - by Sevas
    I have a virtual machine (Debian) running on a physical machine host. The virtual machine acts as a buffer for data that it frequently receives over the local network (the period for this data is 0.5s, so a fairly high throughput). Any data received is stored on the virtual machine and repeatedly forwarded to an external server over UDP. Once the external server acknowledges (over UDP) that it has received a data packet, the original data is deleted from the virtual machine and not sent to the external server again. The internet connection that connects the VM and the external server is unreliable, meaning it could be down for days at a time. The physical machine that hosts the VM gets its power cut several times per day at random. There is no way to tell when this is about to happen and it is not possible to add a UPS, a battery, or a similar solution to the system. Originally, the data was stored on a file-based HSQLDB database on the virtual machine. However, the frequent power cuts eventually cause the database script file to become corrupted (not at the file system level, i.e. it is readable, but HSQLDB can't make sense of it), which leads to my question: How should data be stored in an environment where power cuts can and do happen frequently? One option I can think of is using flat files, saving each packet of data as a file on the file system. This way if a file is corrupted due to loss of power, it can be ignored and the rest of the data remains intact. This poses a few issues however, mainly related to the amount of data likely being stored on the virtual machine. At 0.5s between each piece of data, 1,728,000 files will be generated in 10 days. This at least means using a file system with an increased number of inodes to store this data (the current file system setup ran out of inodes at ~250,000 messages and 30% disk space used). Also, it is hard (not impossible) to manage. Are there any other options? Are there database engines that run on Debian that would not get corrupted by power cuts? Also, what file system should be used for this? ext3 is what is used at the moment. The software that runs on the virtual machine is written using Java 6, so hopefully the solution would not be incompatible.

  • Resetting root password on Fedora Core 3 - serial cable access only

    - by Sensible Eddie
    A little background: We have an old rackmount server running a customised version of Fedora, manufactured by a company called Navaho. The server is a TeamCAT, running some proprietary rubbish called Freedom2. We have to keep it going - the alternative is extraordinarily expensive, and the business is not likely to be running much longer to justify changing things. Through one means or another, it has fallen upon me to try and resolve our lack of root access. The previous admin has fallen under the proverbial bus, and nobody has any clue. We have no access to the root account for this server. ssh is running on the server, and there is one account admin that we can login with, however it has no permission to do anything (ironic...) The only other way into the server is with a null-modem serial cable. This works... up to a point. I can see the BIOS, I can see the post BIOS screen, and then I see "Starting grub", followed by another screen with about four lines of Linux information, but then it stops at that point. The server continues booting, and all services come online after around two minutes, but the serial terminal displays no more information. I understand it is possible to put Linux into "single user mode" to reset a root password, but I have no idea how to do this beyond trying to interrupt it at the grub stage listed above. When I have tried it just froze. It was almost like grub had appeared (since the server did not continue booting) but I couldn't see it on the serial terminal. Which made me think maybe the grub screen has some different serial settings? I don't know... it's the first time I've ever used serial for access! A friend of mine suggested trying to use a Fedora boot CD. We could boot from USB, so something along this approach is possible but again we still can only see what's going on with the serial terminal, so it might not be achievable. Does anyone have any suggestions for things I can try? I appreciate this is a bit of a long shot, but any assistance would be invaluable. *UPDATE 1 - 28/8/12 * - we will be making some attempts on this today and will post further details later!

  • Migrating users and IIS settings from a workgroup win2k3 machine to a new win2k8r2

    - by amber
    I am retiring my old Windows Server 2003 Standard 32bit machine to a new machine with Windows Server 2008 R2 Standard. The two sticking points are migrating user accounts (and there are a lot of them) and IIS settings/websites (again, there are a lot). The new machine has not been provisioned yet. I'm at that point where I'm about install the OS on it. The old machibe is configured with a mirrored set for its OS and data partitions. I have broken the mirror set, replicated all of the data to an external drive, and then rebuilt the mirror set. In short, I have an image of the old machine to play with while safely leaving it up and running. Thanks!

  • Outbound ports to allow through firewall - core requirements

    - by dunxd
    This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support email and web access, which I know everyone will need: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working? I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

  • Any way to disable specific CPU idle (Cx) states?

    - by Philippe
    I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy. FYI: I'm running Windows 7 64-bit

  • Move MySQL master

    - by Noodles
    I currently have a master db server (lets call it db1) and 6 slaves (slave1-6). I've setup a new server (db2) as a slave of db1 and it's in sync. I want to change all the slaves to use db2 instead of db1, but with minimal downtime/data loss. At the moment the only way I can think of doing it is shutting down our website (so data stops being written to db1), waiting until all the slaves are up to date, flush logs on db1, shut it down. Reset master on db2, change all slaves to point to db2 with log position = 0. Is this the right way to do it or is there a way to do it without taking the site offline?

  • sqlalchemy date type in 0.6 migration using mssql

    - by nosklo
    I'm connection to mssql server through pyodbc, via FreeTDS odbc driver, on linux ubuntu 10.04. Sqlalchemy 0.5 uses DATETIME for sqlalchemy.Date() fields. Now Sqlalchemy 0.6 uses DATE, but sql server 2000 doesn't have a DATE type. How can I make DATETIME be the default for sqlalchemy.Date() on sqlalchemy 0.6 mssql+pyodbc dialect? I'd like to keep it as clean as possible. Here's code to reproduce the issue: import sqlalchemy from sqlalchemy import Table, Column, MetaData, Date, Integer, create_engine engine = create_engine( 'mssql+pyodbc://sa:sa@myserver/mydb?driver=FreeTDS') m = MetaData(bind=engine) tb = sqlalchemy.Table('test_date', m, Column('id', Integer, primary_key=True), Column('dt', Date()) ) tb.create() And here is the traceback I'm getting: Traceback (most recent call last): File "/tmp/teste.py", line 15, in <module> tb.create() File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/schema.py", line 428, in create bind.create(self, checkfirst=checkfirst) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1647, in create connection=connection, **kwargs) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1682, in _run_visitor **kwargs).traverse_single(element) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/sql/visitors.py", line 77, in traverse_single return meth(obj, **kw) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/ddl.py", line 58, in visit_table self.connection.execute(schema.CreateTable(table)) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1157, in execute params) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1210, in _execute_ddl return self.__execute_context(context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1268, in __execute_context context.parameters[0], context=context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1367, in _cursor_execute context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1360, in _cursor_execute context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/default.py", line 277, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.ProgrammingError: (ProgrammingError) ('42000', '[42000] [FreeTDS][SQL Server]Column or parameter #2: Cannot find data type DATE.

  • S#harp architecture mapping many to many and ado.net data services: A single resource was expected f

    - by Leg10n
    Hi, I'm developing an application that reads data from a SQL server database (migrated from a legacy DB) with nHibernate and s#arp architecture through ADO.NET Data services. I'm trying to map a many-to-many relationship. I have a Error class: public class Error { public virtual int ERROR_ID { get; set; } public virtual string ERROR_CODE { get; set; } public virtual string DESCRIPTION { get; set; } public virtual IList<ErrorGroup> GROUPS { get; protected set; } } And then I have the error group class: public class ErrorGroup { public virtual int ERROR_GROUP_ID {get; set;} public virtual string ERROR_GROUP_NAME { get; set; } public virtual string DESCRIPTION { get; set; } public virtual IList<Error> ERRORS { get; protected set; } } And the overrides: public class ErrorGroupOverride : IAutoMappingOverride<ErrorGroup> { public void Override(AutoMapping<ErrorGroup> mapping) { mapping.Table("ERROR_GROUP"); mapping.Id(x => x.ERROR_GROUP_ID, "ERROR_GROUP_ID"); mapping.IgnoreProperty(x => x.Id); mapping.HasManyToMany<Error>(x => x.Error) .Table("ERROR_GROUP_LINK") .ParentKeyColumn("ERROR_GROUP_ID") .ChildKeyColumn("ERROR_ID").Inverse().AsBag(); } } public class ErrorOverride : IAutoMappingOverride<Error> { public void Override(AutoMapping<Error> mapping) { mapping.Table("ERROR"); mapping.Id(x => x.ERROR_ID, "ERROR_ID"); mapping.IgnoreProperty(x => x.Id); mapping.HasManyToMany<ErrorGroup>(x => x.GROUPS) .Table("ERROR_GROUP_LINK") .ParentKeyColumn("ERROR_ID") .ChildKeyColumn("ERROR_GROUP_ID").AsBag(); } } When I view the Data service in the browser like: http://localhost:1905/DataService.svc/Errors it shows the list of errors with no problems, and using it like http://localhost:1905/DataService.svc/Errors(123) works too. The Problem When I want to see the Errors in a group or the groups form an error, like: "http://localhost:1905/DataService.svc/Errors(123)?$expand=GROUPS" I get the XML Document, but the browser says: The XML page cannot be displayed Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later. -------------------------------------------------------------------------------- Only one top level element is allowed in an XML document. Error processing resource 'http://localhost:1905/DataServic... <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> -^ I view the sourcecode, and I get the data. However it comes with an exception: <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> <code></code> <message xml:lang="en-US">An error occurred while processing this request.</message> <innererror xmlns="xmlns"> <message>A single resource was expected for the result, but multiple resources were found.</message> <type>System.InvalidOperationException</type> <stacktrace> at System.Data.Services.Serializers.Serializer.WriteRequest(IEnumerator queryResults, Boolean hasMoved)&#xD; at System.Data.Services.ResponseBodyWriter.Write(Stream stream)</stacktrace> </innererror> </error> A I missing something???

  • PHP/MySQL time zone migration

    - by El Yobo
    I have an application that currently stores timestamps in MySQL DATETIME and TIMESTAMP values. However, the application needs to be able to accept data from users in multiple time zones and show the timestamps in the time zone of other users. As such, this is how I plan to amend the application; I would appreciate any suggestions to improve the approach. Database modifications All TIMESTAMPs will be converted to DATETIME values; this is to ensure consistency in approach and to avoid having MySQL try to do clever things and convert time zones (I want to keep the conversion in PHP, as it involves less modification to the application, and will be more portable when I eventually manage to escape from MySQL). All DATETIME values will be adjusted to convert them to UTC time (currently all in Australian EST) Query modifications All usage of NOW() to be replaced with UTC_TIMESTAMP() in queries, triggers, functions, etc. Application modifications The application must store the time zone and preferred date format (e.g. US vs the rest of the world) All timestamps will be converted according to the user settings before being displayed All input timestamps will be converted to UTC according to the user settings before being input Additional notes Converting formats will be done at the application level for several main reasons The approach to converting time zones varies from DB to DB, so handing it there will be non-portable (and I really hope to be migrating away from MySQL some time in the not-to-distant future). MySQL TIMESTAMPs have limited ranges to the permitted dates (~1970 to ~2038) MySQL TIMESTAMPs have other undesirable attributes, including bizarre auto-update behaviour (if not carefully disabled) and sensitivity to the server zone settings (and I suspect I might screw these up when I migrate to Amazon later in the year). Is there anything that I'm missing here, or does anyone have better suggestions for the approach?

  • Data Warehouse ETL slow - change primary key in dimension?

    - by Jubbles
    I have a working MySQL data warehouse that is organized as a star schema and I am using Talend Open Studio for Data Integration 5.1 to create the ETL process. I would like this process to run once per day. I have estimated that one of the dimension tables (dimUser) will have approximately 2 million records and 23 columns. I created a small test ETL process in Talend that worked, but given the amount of data that may need to be updated daily, the current performance will not cut it. It takes the ETL process four minutes to UPDATE or INSERT 100 records to dimUser. If I assumed a linear relationship between the count of records and the amount of time to UPDATE or INSERT, then there is no way the ETL can finish in 3-4 hours (my hope), let alone one day. Since I'm unfamiliar with Java, I wrote the ETL as a Python script and ran into the same problem. Although, I did discover that if I did only INSERT, the process went much faster. I am pretty sure that the bottleneck is caused by the UPDATE statements. The primary key in dimUser is an auto-increment integer. My friend suggested that I scrap this primary key and replace it with a multi-field primary key (in my case, 2-3 fields). Before I rip the test data out of my warehouse and change the schema, can anyone provide suggestions or guidelines related to the design of the data warehouse the ETL process how realistic it is to have an ETL process INSERT or UPDATE a few million records each day will my friend's suggestion significantly help If you need any further information, just let me know and I'll post it. UPDATE - additional information: mysql> describe dimUser; Field Type Null Key Default Extra user_key int(10) unsigned NO PRI NULL auto_increment id_A int(10) unsigned NO NULL id_B int(10) unsigned NO NULL field_4 tinyint(4) unsigned NO 0 field_5 varchar(50) YES NULL city varchar(50) YES NULL state varchar(2) YES NULL country varchar(50) YES NULL zip_code varchar(10) NO 99999 field_10 tinyint(1) NO 0 field_11 tinyint(1) NO 0 field_12 tinyint(1) NO 0 field_13 tinyint(1) NO 1 field_14 tinyint(1) NO 0 field_15 tinyint(1) NO 0 field_16 tinyint(1) NO 0 field_17 tinyint(1) NO 1 field_18 tinyint(1) NO 0 field_19 tinyint(1) NO 0 field_20 tinyint(1) NO 0 create_date datetime NO 2012-01-01 00:00:00 last_update datetime NO 2012-01-01 00:00:00 run_id int(10) unsigned NO 999 I used a surrogate key because I had read that it was good practice. Since, from a business perspective, I want to keep aware of potential fraudulent activity (say for 200 days a user is associated with state X and then the next day they are associated with state Y - they could have moved or their account could have been compromised), so that is why geographic data is kept. The field id_B may have a few distinct values of id_A associated with it, but I am interested in knowing distinct (id_A, id_B) tuples. In the context of this information, my friend suggested that something like (id_A, id_B, zip_code) be the primary key. For the large majority of daily ETL processes (80%), I only expect the following fields to be updated for existing records: field_10 - field_14, last_update, and run_id (this field is a foreign key to my etlLog table and is used for ETL auditing purposes).

  • Accessing Server-Side Data from Client Script: Accessing JSON Data From an ASP.NET Page Using jQuery

    When building a web application, we must decide how and when the browser will communicate with the web server. The ASP.NET WebForms model greatly simplifies web development by providing a straightforward mechanism for exchanging data between the browser and the server. With WebForms, each ASP.NET page's rendered output includes a <form> element that performs a postback to the same page whenever a Button control within the form is clicked, or whenever the user modifies a control whose AutoPostBack property is set to True. On postback, the server sends the entire contents of the web page back to the browser, which then displays this new content. With WebForms we don't need to spend much time or effort thinking about how or when the browser will communicate with the server or how that returned information will be processed by the browser. It just works. While this approach certainly works and has its advantages, it's not without its drawbacks. The primary concern with postback forms is that they require a large amount of information to be exchanged between the browser and the server. Specifically, the browser sends back all of its form fields (including hidden ones, like view state, which may be quite large) and then the server sends back the entire contents of the web page. Granted, there are scenarios where this large quantity of data needs to be exchanged, but in many cases we can use techniques that exchange much less information. However, these techniques necessitate spending more time and effort thinking about how and when to have the browser communicate with the server and intelligently deciding on what information needs to be exchanged. This article, the first in a multi-part series, examines different techniques for accessing server-side data from a browser using client-side script. Throughout this series we will explore alternative ways to expose data on the server so that it can be accessed from the browser using script; we will also examine various tools for communicating with the server from JavaScript, including jQuery and the ASP.NET AJAX library.
