  • Are L'A' and 'A' totally same?

    - by Benjamin
    When we write a program which supports both unicode and multibytes, we often use _T("some string") macro for strings. But, does a character also need to wrap this macro? Are L'A' and 'A' totally same? Don't we need to use _T('A') for a character?

  • How to benchmark functions in clojure

    - by Peter Tillemans
    I know I can get the time take to evaluate a function can be printed out on the screen/stdout using the time function/macro. The time macro returns the value of the evaluated function, which makes it great to use it inline. However I want to automatically measure the runtime under specific circumstances. is there a function which returns the elapsed time in some library to hep with this benchmarking?

  • How to print 5 byte integer values?

    - by lost soul
    I've just started reading C and have a question about a macro. How can I print a 5 byte integer value (that happens to be defined in a macro)? For example: #define MAX 0xdeadbeaf12 int main(){ printf(" 0x %2x \n", MAX); } This code prints adbeaf12 but not deadbeaf12. How do I get all the bytes printed?

  • Difference between macros and functions in C in relation to instruction memory and speed

    - by DAHANS
    To my understanding the difference between a macro and a function is, that a macro-call will be replaced by the instruction in the definition, and a function does the whole push, branch and pop -thing. Is this right, or have I understand something wrong? Additionally, if this is right, it would mean, that macros would take more space, but would be faster (because of the lack of the push,branch and pop instructions.), wouldn't it?

  • Will this RAID5 setup work (3TB Seagate Barracudas + Adaptec RAID 6405)?

    - by Slayer537
    As the title states, will this RAID combo work, and if not what needs to be changed? Overall opinions would be most helpful. I currently run a small file server of about 5TB or so. I keep outgrowing my needs and need to build a RAID setup that will allow me to expand as needed. I am new to RAID setups, especially one of the scale I have currently planned out, but I have being doing some research for the past couple of weeks and have come up with a build. Ideally, I'd have the setup completely built, but I'd like to keep the total cost around $1k and can't afford to go above $1.5k, so unfortunately that's not an option. 2 of my current drives are WD Caviar Blacks 2TB; however, I have recently learned that due to the lack of TLER those drives are awful for any RAID setup other than 0 or 1. That being said, my third drive is a Seagate Barracuda 3TB (ST300DM001) and I have found a RAID controller that states it supports it, so I'd like to use this same type of drive, if possible. Have any of you had any experience using this drive or a similar one in a RAID5 configuration? The manufacturer states that it supports it, but knowing that it is not an enterprise drive, I am slightly concerned that it could drop out of the array. I would just go with enterprise drives, but those are about double in cost... Parts list: Storage rack: http://www.ebay.com/itm/SGI-3U-Media-Storage-Server-16-Hard-Drive-Bay-SATA-SAS-Expander-Omnistor-SE3016-/140735776937?pt=LH_DefaultDomain_0&hash=item20c48188a9 3 more HDs (for now..): http://www.amazon.com/Seagate-Barracuda-3-5-Inch-Internal-ST3000DM001/dp/B005T3GRLY/ref=dp_return_2?ie=UTF8&n=172282&s=electronics Adaptec RAID 6405: http://www.newegg.com/Product/Product.aspx?Item=N82E16816103224 here's a link to the compatibility sheet if that helps: http://download.adaptec.com/pdfs/compatibility_report/arc-sas_cr_03-27-12_series6.pdf SAS expander cable: http://www.pc-pitstop.com/sas_cables_adapters/8887-2M.asp My plan is to install the RAID card in my computer and then route the SAS cable to the rack. Setup a RAID5 on 3 drives, transfer my data over from my other drive, and then add that drive to the array. Eventually, I'd like to get a 2U unit and run the file server on that and move the RAID card over to there, but that will have to happen later on. Side note: The computer the card would be going into will be running Windows 7 Pro with 24GB of DDR3-1600 and an i7-930.

  • Strange messages on new Dell Workstation during bootup

    - by dan99t
    I recently installed Windows 7 Ultimate on a new Dell T-7500 Workstation, and am seeing some strange messages on the screen: Dell SAS 6 Host Bus Adapter BIOS MPTBIOS 6.22.03.00 ( 2008.08.06 ) Initializing….. Press Ctrl – C to run SAS Configuration Utility Searching for Devices at HBA 0….. Dell MPT Boot ROM Successfully installed Then it loads Windows 7. All of above happens on its own, I don't touch anything. So what is going on & what do I have to do get rid off those initializing commands ? I have never had this happen to any previously owned Dell systems. Also I haven't installed any drivers yet but Sound, Video & Internet does work. Do I need to install any additional drivers?

  • Building optimal custom machine for Sql Server

    - by Chad Grant
    Getting the hardware in the mail any day. Hardware related to my question: x10 15.5k RPM SAS Segate Cheetah's x2 Adaptec 5405 PCIe Raid cards Motherboard has integrated SAS raid. Was thinking I would build 2 RAID 10 arrays one for data and one for logs The remaining 2 drives a RAID 0 for TempDB Will probably throw in a drive for OS. Does putting the Sql Server application / exe's on a raid make a difference and is there any impact of leaving the OS on a relatively slow disk compared to the raid arrays? I have 5/6 DBs combined < 50 gigs. With a relatively good / constant load. Estimating 60-7% reads vs writes. Planning on using log shipping as well if that matters. Any advice or suggestions?

  • Horrible performing RAID

    - by Philip
    I have a small GlusterFS Cluster with two storage servers providing a replicated volume. Each server has 2 SAS disks for the OS and logs and 22 SATA disks for the actual data striped together as a RAID10 using MegaRAID SAS 9280-4i4e with this configuration: http://pastebin.com/2xj4401J Connected to this cluster are a few other servers with the native client running nginx to serve files stored on it in the order of 3-10MB. Right now a storage server has a outgoing bandwith of 300Mbit/s and the busy rate of the raid array is at 30-40%. There are also strange side-effects: Sometimes the io-latency skyrockets and there is no access possible on the raid for 10 seconds. The file system used is xfs and it has been tuned to match the raid stripe size. Does anyone have an idea what could be the reason for such a bad performing array? 22 Disks in a RAID10 should deliver way more throughput.

  • Gigabyte Motherboard + Adaptec RAID = No Booting from any drives

    - by Farseeker
    I have a brand new PC, just out of the box. It has a Gigabyte GA-P55-USB3 motherboard. I also have an Adaptec ASR-2504 SAS RAID card with 2x 15k Seagate Barracuda SAS drives attached. After the motherboard init's its on-board RAID it then init's the Adaptec RAID. It detects all the RAID devices OK, but when it gets to Loading Operating System... (i.e. right before it should load the OS) it just sits there forever, doing nothing: If I force it to boot from the optical drive, you see it spin up for a few seconds then die down again. If I remove the Adaptec RAID card, everything works perfectly. As soon as it's plugged back in, it never gets past that stage. The RAID card should be perfectly fine (it was before), but I have raised a case with Adaptec anyway. Any suggestions on what I can try to get these two to play nicely together?

  • Throughput = BS * IOPS?

    - by Marvin
    I've seen in many places that throughput = bs * iops should be true. For example writing at 128k block size to a SAS disk that can support 190 IOPS should give a throughput of ~23 MBps - 23.75(MBs) = 128(BS)*190(SAS-15 IOPS)/1024. Now when I tested it in a VM against a monster NetApp filer I got theses results: # dd if=/dev/zero of=/tmp/dd.out bs=4k count=2097152 8589934592 bytes (8.6 GB) copied, 61.5996 seconds, 139 MB/s To view the IO rate of the VM I used iostat and esxtop, and they both showed around 250 IOPS. So to my understanding the throughput was supposed to be ~1000k: 1000(KBs) = 4(BS)*250(IOPS). dd of 8GB is twice the size of RAM of course, so no page caching here. What am I missing? Thanks!

  • Upgrading drives on a MD3000

    - by Anonymouse
    Hello, Our MD3000 array is getting full as our databases are growing and we need more spaces. Currently, we use a MD3000 with a two-servers Windows 2003 cluster and 15x 73GB SAS drives. Disk groups are configured in RAID1 of two drives. The approach we are currently investigating is simply swapping the existing SAS drives with bigger ones (300GB instead of 73GB), one at a time, and let each RAID1 array rebuilt. Is it a good approach? Will we be able to resize the array afterwards? Will we be able to resize the partitions afterwards? Can the Dell M3000 Management software do it or will we have to bring the server offline and use some partition software to do it? Thanks in advance.

  • Methodologies for performance-testing a WAN link

    - by Chopper3
    We have a pair of new diversely-routed 1Gbps Ethernet links between locations about 200 miles apart. The 'client' is a new reasonably-powerful machine (HP DL380 G6, dual E56xx Xeons, 48GB DDR3, R1 pair of 300GB 10krpm SAS disks, W2K8R2-x64) and the 'server' is a decent enough machine too (HP BL460c G6, dual E55xx Xeons, 72GB, R1 pair of 146GB 10krpm SAS disks, dual-port Emulex 4Gbps FC HBA linked to dual Cisco MDS9509s then onto dedicated HP EVA 8400 with 128 x 450GB 15krpm FC disks, RHEL 5.3-x64). Using SFTP from the client we're only seeing about 40Kbps of throughput using large (2GB) files. We've performed server to 'other local server' tests and see around 500Mbps through the local switches (Cat 6509s), we're going to do the same on the client side but that's a day or so away. What other testing methods would you use to prove to the link providers that the problem is theirs?

  • Using old RAID configured disk after new disk has been used in the controller

    - by Narendra
    I have Dell Poweredge T100 server with Dell SAS 6 and two hard disk on RAID 1. Last week the server died including one RAID 1 hard disk. We sent the server for repair and the problem with PSU was fixed. But the repair guys also checked the RAID controller by configuring new RAID with their test hard disk. Now if I install one working RAID 1 disk and one new disk, will the RAID controller let me continue my old RAID 1 and resync the new disk and continue? What I fear is the RAID controller will want the test hard from repair guys. Thus I have to re configure RAID 1 forcing me to wipe the working disc. If so, I've to backup the working disc, reconfigure RAID 1 and reinstall? Or is there better way? Note: I'm using DELL SAS confiugratio utility to manage RAID. (Press CTRL+C after BIOS)

  • SAB BizTalk Archiving Pipeline Component - Codeplex

    - by Stuart Brierley
    In an effort to give a little more to the BizTalk development community, I have created my first Codeplex project. The SAB BizTalk Archiving Pipeline Component was written using Visual Studio 2010 with BizTalk Server 2010 intended as the target platform.  It is currently at version 0.1, meaning that I have not yet completed all the intended functionality and have so far carried out a limited number of tests.  It does however archive files within the bounds of the functionailty so far implemented and seems to be stable in use. It is based on a recent evolution of a basic archiving component that I wrote in the past, and it is my hope that it will continue to evolve in the coming months. This work was inspired by some old posts by Gilles Zunino and Jeff Lynch.   You can download the documentation, source code or component dll from Codeplex, but to give you a taste here is the first section of the documentation to whet your appetite: SAB BizTalk Archiving Pipeline Component   The SAB BizTalk Archiving Pipeline Component has been developed to allow custom piplelines to be created that can archive messages at any stage of pipeline processing.   It works in both receive and send pipelines and will archive messages to file based on the configuration applied to the component in the BizTalk Administration Console.   The Archiving Pipeline Component has been coded for use with BizTalk Server 2010. Use with other versions of BizTalk has not been tested.   The Archiving Pipeline component is supplied as a dll file that should be placed in the BizTalk Server Pipeline Components folder. It can then be used when developing custom pipelines to be deployed as a part of your BizTalk Server applications.   This version of the component allows you to use a number of generic messaging macros and also a small number that are specific to the FILE adapter. It is intended to extend these macros to cover context properties from other adapters in future releases.     Archive Pipeline Parameters As with all pipeline components, the following parameters can be set when creating your custom pipeline and at runtime via the administration console.   Enabled:              Enables and disables the archive process.                                 True; messages will be archived.   False; messages will be passed to the next stage in the pipeline without performing any processing.   File Name:          The file name of the archived message.   Allows the component to build the archive filename at run-time; based on the values entered, the permitted macros and data extracted from the message context properties.   e.g.        %FileReceivedFileName%-%InterchangeSequenceNumber%   File Mask:           The extension to be added to the File Name following all Macro processing.   e.g.        .xml   File Path:             The path on which the archived message should be saved.   Allows the component to build the archive directory at run-time; based on the values entered, permitted macros and data extracted from the message context properties.   e.g.        C:\Archive\%ReceivePortName%\%Year%\%Month%\%Day%\                   \\ArchiveShare\%ReceivePortName%\%Date%\     Overwrite:          Enables and disables existing file overwrites.   True; any existing file with the same File Path/Name combination (following macro replacement) will be overwritten.   False; any existing file with the same File Path/Name combination (following macro replacement) will not be overwritten.  The current message will be archived with a GUID appended to the File Name.

  • What is the SharePoint Action Framework and Why do I need it ?

    - by SAF
    For those out there that are a little curious as to whether SAF is any use to your organisation, please read this FAQ.  What is SAF ? SAF is free to use. SAF is the "SharePoint Action Framework", it was built by myself and Hugo (plus a few others along the way). SAF is written entirely in C# code available from : http://saf.codeplex.com.   SAF is a way to automate SharePoint configuration changes. An Action is a command/class/task/script written in C# that performs a unit of execution against SharePoint such as "CreateWeb"  or "AddLookupColumn". A SAF Macro is collection of one or more Actions. SAF Macro can be run from Msbuild, a Feature, StsAdm or common plain old .Net code. Parameters can be passed to a Macro at run-time from a variety of sources such as "Environment Variable", "*.config", "Msbuild Properties", Feature Properties, command line args, .net code. SAF emits lots of trace statements at run-time, these can be viewed using "DebugView". One Action can pass parameters to another Action. Parameters can be set using Expression Syntax such as "DateTime.Now".  You should consider SAF is you suffer from one of the following symptoms... "Our developers write lots of code to deploy changes at release time - it's always rushed" "I don't want my developers shelling out to Powershell or Stsadm from a Feature". "We have loads of Console applications now, I have lost track of where they are, or what they do" "We seem to be writing similar scripts against SharePoint in lots of ways, testing is hard". "My scripts often have lots of errors - they are done at the last minute". "When something goes wrong - I have no idea what went wrong or how to solve it". "Our Features get stuck and bomb out half way through - there no way to roll them back". "We have tons of Features now - I can't keep track". "We deploy Features to run one-off tasks" "We have a library of reusable scripts, but, we can only run it in one way, sometimes we want to run it from MSbuild and a Feature". "I want to automate the deployment of changes to our development environment". "I would like to run a housekeeping task on a scheduled basis"   So I like the sound of SAF - what's the problems ?  Realistically, there are few things that need to be considered: Someone on your team will need to spend a day or 2 understanding SAF and deciding exactly how you want to use it. I would suggest a Tech Lead, SysAdm or SP Architect will need to download it, try out the examples, look through the unit tests. Ask us questions. Although, SAF can be downloaded and set to go in a few minutes, you will still need to address issues such as - "Do you want to execute your Macros in MsBuild or from a Feature ?" You will need to decide who is going to do your deployments - is it each developer to themself, or do you require a dedicated Build Manager ? As most environments (Dev, QA, Live etc) require different settings (e.g. Urls, Database names, accounts etc), you will more than likely want to define these and set a properties file up for each environment. (These can then be injected into Saf at run-time). There may be no Action to solve your particular problem. If this is the case, suggest it to us - we can try and write it, or write it yourself. It's very easy to write a new Action - we have an approach to easily unit test it, document it and author it. For example, I wrote one to deploy  a WSP in 2 hours the other day. Alternatively, Saf can also call Stsadm commands and Powershell scripts.   Anyway, I do hope this helps! If you still need help, or a quick start, we can also offer consultancy around SAF. If you want to know more give us a call or drop an email to [email protected]

  • Boost in Visual Studio 2010, IntelliSense error

    - by Peretz
    Hello, I would like to see if you could orient me. It happens that I compiled and referenced the boost libraries in order to use them with Visual Studio 2010. When building my test project I get these two IntelliSense errors 1 IntelliSense: #error directive: "Macro BOOST_LIB_NAME not set (internal error)" c:\boost_1_43_0\boost\config\auto_link.hpp 2 IntelliSense: #error directive: "some required macros where not defined (internal logic error)." c:\boost_1_43_0\boost\config\auto_link.hpp Checking the auto_link.hpp header file the first error is in this line #ifndef BOOST_LIB_NAME # error "Macro BOOST_LIB_NAME not set (internal error)" #endif Tracing the definition of BOOST_LIB_NAME, it seems that is defined in config.hpp by boost_regex, which code I am including below #if !defined(BOOST_REGEX_NO_LIB) && !defined(BOOST_REGEX_SOURCE) && !defined(BOOST_ALL_NO_LIB) && defined(__cplusplus) # define BOOST_LIB_NAME boost_regex # if defined(BOOST_REGEX_DYN_LINK) || defined(BOOST_ALL_DYN_LINK) # define BOOST_DYN_LINK ... more code and strangely when I point to BOOST_LIB_NAME it defines BOOST_LIB_NAME and the IntelliSense errors disappear. My program builds and executes fine using the Boost:Regex library -- with or without the Intellisense errors; however, I do not understand why these IntelliSense errors appear in the first place, and second why pointing the macro in the config.hpp defines BOOST_LIB_NAME. Any guidance will be greatly appreciated. Thanks, Jaime

  • How to prevent latex memory overflow

    - by drasto
    I've got a latex macro that makes small pictures. In that picture I need to draw area. Borders of that area are quadratic bezier curves and that area is to be filled. I did not know how to do it so currently I'm "filling" the area by drawing a plenty of bezier curves inside it... This slows down typeseting and when a macro is used multiple times (so tex is drawing really a lot of quadratic bezier curves) it produces following error: ! TeX capacity exceeded, sorry [main memory size=3000000]. How can I prevent this error ? (by freeing memory after macro or such...) Or even better how do I fill the area determined by two quadratic bezier curves? Code that produces error: \usepackage{forloop} \usepackage{picture} \usepackage{eepic} ... \linethickness{\lineThickness\unitlength}% \forloop[\lineThickness]{cy}{\cymin}{\value{cy} < \cymax}{% \qbezier(\ax, \ay)(\cx, \value{cy})(\bx, \by)% }% Here are some example values for variables: \setlength{\unitlength}{0.01pt} \lineThickness=20 %cy is just a counter - inital value is not important \cymin=450 \cymax=900 %from following only the difference between \ax and \bx is important \ax=0 \ay=0 \bx=550 \by=0 Note: To reproduce the error this code have to execute approximately 150 times (could be more depending on your latex memory settings). Thanks a lot for any help

  • Excel VBA Select Case Loop Sub

    In my excel file, I have a table setup with formulas. with Cells from Range("B2:B12"), Range ("D2:D12"), and etc every other row containing the answers to these formulas. for these cells (with the formula answers), I need to apply conditional formatting, but I have 7 conditions, so I've been using "select case" in VBA to change their interior background based on their number. I have the select case function currently set up within the sheet code, as opposed to it's own macro Private Sub Worksheet_Change(ByVal Target As Range) Dim iColor As Integer If Not Intersect(Target, Range("B2:L12")) Is Nothing Then Select Case Target Case 0 iColor = 2 Case 0.01 To 0.49 iColor = 36 Case 0.5 To 0.99 iColor = 6 Case 1 To 1.99 iColor = 44 Case 2 To 2.49 iColor = 45 Case 2.5 To 2.99 iColor = 46 Case 3 To 5 iColor = 3 End Select Target.Interior.ColorIndex = iColor End If End Sub but using this method, you must be actually entering the value into the cell for the formatting to work. which is why I want to write a subroutine to to do this as a macro. I can input my data, let the formulas work, and when everything is ready, I can run the macro and format those specific cells. I want an easy way to do this, obviously I could waste a load of time, typing out all the cases for every cell, but I figured it'd be easier with a loop. how would I go about writing a select case loop to change the formatting on a a specific range of cells every other row? thank you in advance.

  • How can I SETF an element in a tree by an accessor?

    - by Willi Ballenthin
    We've been using Lisp in my AI course. The assignments I've received have involved searching and generating tree-like structures. For each assignment, I've ended up writing something like: (defun initial-state () (list 0 ; score nil ; children 0 ; value 0)) ; something else and building my functions around these "states", which are really just nested lists with some loosely defined structure. To make the structure more rigid, I've tried to write accessors, such as: (defun state-score ( state ) (nth 2 state)) This works for reading the value (which should be all I need to do in a nicely functional world. However, as time crunches, and I start to madly hack, sometimes I want a mutable structure). I don't seem to be able to SETF the returned ...thing (place? value? pointer?). I get an error with something like: (setf (state-score *state*) 10) Sometimes I seem to have a little more luck writing the accessor/mutator as a macro: (defmacro state-score ( state ) `(nth 2 ,state)) However I don't know why this should be a macro, so I certainly shouldn't write it as a macro (except that sometimes it works. Programming by coincidence is bad). What is an appropriate strategy to build up such structures? More importantly, where can I learn about whats going on here (what operations affect the memory in what way)?
