• IPC (inter-process communication) server to connect different runtimes

  - by wvxvw

  Couple days ago I've spoken to someone who mentioned a server product that has as its main goal the ability to create inter-runtime layer that allows sharing in-memory object between different languages. The person also described the process of creating such layer as defining a number of structs in a special way such that different languages which access the objects would have the same idea of what the data they access looks like. Unfortunately, I forgot what this product is called, and Google didn't help me finding it so far. Would you happen to know what he was talking about?

• Python unicode Decode Error SUDs

  - by PylonsN00b

  OK so I have # -*- coding: utf-8 -*- at the top of my script and it worked for being able to pull data from the database that had funny chars(Ñ ,Õ,é,—,–,’,…) in it and store that data into variables...but I have run into other problems, see I pull my data, organize it, and then dump it into a variables like so: title = product[1] Where product[1] is from my database result set Then I load it up for Suds like so: array_of_inventory_item_submit = ca_client_inventory.factory.create('ArrayOfInventoryItemSubmit') for product in products: inventory_item_submit = ca_client_inventory.factory.create('InventoryItemSubmit') inventory_item_list = get_item_list(product) inventory_item_submit = [inventory_item_list] array_of_inventory_item_submit.InventoryItemSubmit.append(inventory_item_submit) #Call that service baby! ca_client_inventory.service.SynchInventoryItemList(accountID, array_of_inventory_item_submit) Where get_item_list sets product[1] to title and (including a whole bunch of other nodes): inventory_item_submit.Title = title So everything runs fine until I call ca_client_inventory.service.SynchInventoryItemList that contains array_of_inventory_item_submit which contains the title w/ the funky char...here is the error: Traceback (most recent call last): File "upload_all_inventory_ebay.py", line 421, in <module> ca_client_inventory.service.SynchInventoryItemList(accountID, array_of_inventory_item_submit) File "build/bdist.macosx-10.6-i386/egg/suds/client.py", line 539, in __call__ File "build/bdist.macosx-10.6-i386/egg/suds/client.py", line 592, in invoke File "build/bdist.macosx-10.6-i386/egg/suds/bindings/binding.py", line 118, in get_message File "build/bdist.macosx-10.6-i386/egg/suds/bindings/document.py", line 63, in bodycontent File "build/bdist.macosx-10.6-i386/egg/suds/bindings/document.py", line 105, in mkparam File "build/bdist.macosx-10.6-i386/egg/suds/bindings/binding.py", line 260, in mkparam File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 62, in process File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 243, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 298, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 298, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 243, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 198, in append File "build/bdist.macosx-10.6-i386/egg/suds/sax/element.py", line 251, in setText File "build/bdist.macosx-10.6-i386/egg/suds/sax/text.py", line 43, in __new__ UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 116: ordinal not in range(128) Now what? My guess is my script can take in these funky chars because I have # -*- coding: utf-8 -*- at the top but Suds does NOT have that at the top of its files. Do I really want to go and change the Suds files...we all know this is the least desired last possible solution...what can I do?

• Parsing HTML using HtmlParser

  - by Blankman

  My html has 20 or so rows of the following HTML pattern. So the below is considered a single instance of the pattern. Each instance of this pattern represents a product. Again the below is a single instance, it spans multiple rows in the HTML table. <table> .. <!-- product starts here, this html comment is not in the real html --> <tr> <td rowspan="5" class="product" valign="top"><nobr> ????????????</td> </tr> <tr> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> </tr> <tr> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> </tr> </tr> <tr> <td colspan="5" ????????</td> </tr> <tr> <td colspan="6" width="100%">&nbsp;<hr></td> </tr> <!-- product ends here, this html comment is not in the real html --> <!-- above pattern repeats multiple times in the HTML --> .. <table> I am trying to use HtmlParser for this. Parser rowParser = new Parser(); rowParser.setInputHtml(page.getHtml()); // page object represents a html page rowParser.setEncoding("UTF-8"); NodeFilter productRowFilter = new AndFilter( new TagNameFilter("tr"), new HasChildFilter( new AndFilter( new TagNameFilter("td"), new HasAttributeFilter("class", "product"))) The above filter doesn't work, just showing you what I have so far. I need to somehow combine these filters, and use the last td to mark the end of the pattern i.e. the td with the colspan=6 and width=100% with child element hr. I have been struggling with this, and have resorted to Regex'ing but was told numerous times to NOT use regex for html parsing, so here I am! Your help is much appreciated!

• Does anyone have database, programming language/framework suggestions for a GUI point of sale system

  - by Jason Down

  Our company has a point of sale system with many extras, such as ordering and receiving functionality, sales and order history etc. Our main issue is that the system was not designed properly from the ground up, so it takes too long to make fixes and handle requests from our customers. Also, the current technology we are using (Progress database, Progress 4GL for the language) incurs quite a bit of licensing expenses on our customers due to mutli-user license fees for database connections etc. After a lot of discussion it is looking like we will probably start over from scratch (while maintaining the current product at least for the time being). We are looking for a couple of things: Create the system with a nice GUI front end (it is currently CHUI and the application was not built in a way that allows us to redesign the front end... no layering or separation of business logic and gui...shudder). Create the system with the ability to modularize different functionality so the product doesn't have to include all features. This would keep the cost down for our current customers that want basic functionality and a lower price tag. The bells and whistles would be available for those that would want them. Use proper design patterns to make the product easy to add or change any part at any time (i.e. change the database or change the front end without needing to rewrite the application or most of it). This is a problem today because the Progress 4GL code is directly compiled against the database. Small changes in the database requires lots of code recompiling. Our new system will be Linux based, with a possibility of a client application providing functionality from one or more windows boxes. So what I'm looking for is any suggestions on which database and/or framework or programming language(s) someone might recommend for this sort of product. Anyone that has experience in this field might be able to point us in the right direction or even have some ideas of what to avoid. We have considered .NET and SQL Express (we don't need an enterprise level DB), but that would limit us to windows (as far as I know anyway). I have heard of Mono for writing .NET code in a Linux environment, but I don't know much about it yet. We've also considered a Java and MySql based implementation. To summarize we are looking to do the following: Keep licensing costs down on the technology we will use to develop the product (Oracle, yikes! MySQL, nice.) Deliver a solution that is easily maintainable and supportable. A solution that has a component capable of running on "old" hardware through a CHUI front end. (some of our customers have 40+ terminals which would be a ton of cash in order to convert over to a PC). Suggestions would be appreciated. Thanks [UPDATE] I should note that we are currently performing a total cost analysis. This question is intended to give us a couple of "educated" options to look into to include in or analysis. Anyone who could share experiences/suggestions about client/server setups would be appreciated (not just those who have experience with point of sale systems... that would just be a bonus).

• Problem with script to add/delete from database

  - by Jason

  Ok - the user enters a product code, price and name using a form - the script then either adds it to the database or deletes it from the database. If the user is trying to delete a product that is not in the database they get a error message. Upon successful adding/deleting they also get a message. However, when I test it - I just get a blank page. Perl doesnt come up with any warnings, syntax errors or anything - says everything is fine... but I still just get a blank page. The script... #!/usr/bin/perl #c09ex5.cgi - saves data to and removes data from a database print "Content-type: text/html\n\n"; use CGI qw(:standard); use SDBM_File; use Fcntl; use strict; #declare variables my ($code, $name, $price, $button, $codes, $names, $prices); #assign values to variables $code = param('Code'); $name = param('Name'); $price = param('Price'); $button = param('Button'); ($code, $name, $price) = format_input(); ($codes, $names, $prices) = ($code, $name, $price); if ($button eq "Save") { add(); } elsif ($button eq "Delete") { remove(); } exit; sub format_input { $codes =~ s/^ +//; $codes =~ s/ +$//; $codes =~ tr/a-z/A-Z/; $codes =~ tr/ //d; $names =~ s/^ +//; $names =~ s/ +$//; $names =~ tr/ //d; $names = uc($names); $prices =~ s/^ +//; $prices =~ s/ +$//; $prices =~ tr/ //d; $prices =~ tr/$//d; } sub add { #declare variable my %candles; #open database, format and add record, close database tie(%candles, "SDBM_File", "candlelist", O_CREAT|O_RDWR, 0666) or die "Error opening candlelist. $!, stopped"; format_vars(); $candles{$codes} = "$names,$prices"; untie(%candles); #create web page print "<HTML>\n"; print "<HEAD><TITLE>Candles Unlimited</TITLE></HEAD>\n"; print "<BODY>\n"; print "<FONT SIZE=4>Thank you, the following product has been added.<BR>\n"; print "Candle: $codes $names $prices</FONT>\n"; print "</BODY></HTML>\n"; } #end add sub remove { #declare variables my (%candles, $msg); tie(%candles, "SDBM_File", "candlelist", O_RDWR, 0) or die "Error opening candlelist. $!, stopped"; format_vars(); #determine if the product is listed if (exists($candles{$codes})) { delete($candles{$codes}); $msg = "The candle $codes $names $prices has been removed."; } else { $msg = "The product you entered is not in the database"; } #close database untie(%candles); #create web page print "<HTML>\n"; print "<HEAD><TITLE>Candles Unlimited</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H1>Candles Unlimited</H1>\n"; print "$msg\n"; print "</BODY></HTML>\n"; }

• Opening a file with a variable as name & checking for undefined values

  - by Harm De Weirdt

  Hello everyone. I'm having some problems writing data into a file using perl. sub startNewOrder{ my $name = makeUniqueFileName(); open (ORDER, ">$name.txt") or die "can't open file: $!\n"; format ORDER_TOP = PRODUCT<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<CODE<<<<<<<<AANTAL<<<<EENHEIDSPRIJS<<<<<<TOTAAL<<<<<<< . format ORDER = @<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< @<<<<<<<< @<<<< @<<<<<< @<<<<< $title, $code, $amount, $price, $total . close (ORDER); } This is the sub I use to make the file. (I translated most of it) The makeUniqueFileName method makes a fileName based upon current time("minuteshoursdayOrder"). The problem now is that I have to write in this file in another sub. sub addToOrder{ print "give productcode:"; $code = <STDIN>; chop $code; print "Give amount:"; $amount = <STDIN>; chop $amount; if($inventory{$code} eq undef){ #Does the product exist? print "This product does not exist"; }elsif($inventory{$code}[2] < $amount && !defined($inventaris{$code}[2]) ){ #Is there enough in the inventory? print "There is not enough in stock" }else{ $inventory{$code}[2] -= $amount; #write in order file open (ORDER ">>$naam.txt") or die "can't open file: $!\n"; $title = $inventory{$code}[0]; $code = $code; $amount = $inventory{$code}[2]; $price = $inventory{$code}[1]; $total = $inventory{$code}[1]; write; close(ORDER); } %inventory is a hashtable that has the productcode as key and an array with the title, price and amount as value. There are two problems here: when I enter an invalid product number, I still have to enter an amount even while my code says it should print the error directly after checking if there is a product with the given code. The second problem is that the writing doesn't seem to work. It always give's a "No such file or directory" error. Is there a way to open the ORDER file i made in the first sub without having to make $name not local? Or just a way to write in this file? I really don't know how to start here. I can't really find much info on writing a file that has been closed before, and in a different sub.. Any help is appreciated, Harm

• Reinstall Acer OEM Windows 8, Windows 8 Recovery for Acer Aspire V5 122p

  - by stwindr

  My Acer Aspire V5-122P-61456G50NSS, model - MS2377, has crashed all together. It came preloaded with Windows 8 and I upgraded to windows 8.1 3-4 days before crash. Unfortunately I did not make any recovery media before the crash. While accessing the eRecovery on Acer store with my PC's serial no. it says nor RCD available for this. I tried recovery by loading recovery manager (Left Alt + F10) Various other advanced startup options (like holding shift key while turning on or pressing F8 key) returns nothing but no luck. However I am able to enter BIOS. After doing research on above condition on various PC forums, now my questions: I read that a 'Windows Recovery Drive' can be made on any PC running Windows 8 and could be used to repair another PC. Does anybody in SuperUser community have that (or a link to download the same from somewhere? as I'm unable to find anybody running windows 8 among my friends). I downloaded a window 8 Pro ISO and made a bootable USB. I was able to go to 'Repair Your Computer' option and after going to 'Reset your PC' option found that my recovery partition has gone/missing. I tried all options available but no luck. Then I tried to install with that Windows 8 Pro ISO but got message: "The product key entered does not match any of the Windows images available for installation. Enter a different product key". before this message I did not got any form to fill product key! Does this mean that the installer was picking up the key from BIOS (OEM Key)? and may be the installation did not succeeded because OEM Windows version was Window 8 and I was trying to install Windows 8 Pro. If that is the case then, could somebody please send me link to download an Windows 8 ISO? I am helpless and couldn't find anywhere on internet (without having to pay for a new key, but I should not pay as the installer will use OEM key).

  Hello, everybody! I'm experiencing troubles with DCOM configuration. Here is the case: I'm using some product which supports client-server interaction through DCOM, but the client won't get any access to the server if the attempt is being done from an account with a name which exists at the server as well, but has different password. Basically, if we try to access the server from the Administrator account which obviously present on the server machine, we will fail if client's Administrator password doesn't match server's one. After actively collaborating with the product's developer in attempts to localize the issue, he come across with resolution "can't be fixed" or, if you prefer to call a pikestaff a pikestaff than it's more likely a "don't know how to fix" resolution :). I believe there is a solution for this problem and I'm asking you, IT professionals, to help me out with this one. I do realize that the problem may be caused by the way the developer interact with DCOM and if so it can't be fixed be means of pure system configuration and the question should be asked at SO, but since I've bumped into the same behavior while working with file/printer sharing - Windows tried to simplify everything and used currently impersonated credentials to access the share, I hope the solution lies at system configuration layer. P.S. I believe that the actual software product I'm talking about is entirely irrelevant however my experience tell me that there always would be somebody who will think that it on the contrary is very relevant. Here it is: SpRecord.

• Upgrading Visio 2000 to Visio 2007

  - by dirtside

  I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

• SQL Server 2005 SP3 on Windows 7 - No Management Studio

  - by Mike Thomas

  I've been trying for a day and a half now to get SQL Server 2005, DEV edition, to work on Windows 7, 64 bit prof. I install from the disk, then run SP 3. I get a failure on the Client Components section of the Installation Progress along with this vague message - Product : Client Components Product Version (Previous): 1399 Product Version (Final) : Status : Failure Log File : C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix\SQLTools9_Hotfix_KB955706_sqlrun_tools.msp.log Error Number : 1712 Error Description : MSP Error: 1712 One or more of the files required to restore your computer to its previous state could not be found. Restoration will not be possible. I've uninstalled all Visual Studio and tried to make this as clean as possible, and have read a lot of the blog posts, but am really at my wits end about this. I am not a DBA, but I use SQL Server all the time when coding and testing apps. Does anyone have any ideas as to where I can get this sorted out? I've been ati this for a long time and have never encountered an installation as bad as this one. Thanks Mike Thomas

• Re-configure Office 2007 installation unattended: Advertised components --> Local

  - by abstrask

  On our Citrix farm, I just found out that some sub-components are "Installed on 1st Use" (Advertised), which does play well on terminal servers. Not only that, but you also get a rather non-descriptive error message, when a document tried to use a component, which is "Installed on 1st Use" (described on Plan to deploy Office 2010 in a Remote Desktop Services environment): Microsoft Office cannot run this add-in. An error occurred and this feature is no longer functioning correctly. Please contact your system administrator. I have ~50 Citrix servers where I need to change the installation state of all Advertised components to Local, so I created an XML file like this: <?xml version="1.0" encoding="utf-8"?> <Configuration Product="ProPlus"> <Display Level="none" CompletionNotice="no" SuppressModal="yes" AcceptEula="yes" /> <Logging Type="standard" Path="C:\InstallLogs" Template="MS Office 2007 Install on 1st Use(*).log" /> <Option Id="AccessWizards" State="Local" /> <Option Id="DeveloperWizards" State="Local" /> <Setting Id="Reboot" Value="NEVER" /> </Configuration> I run it with a command like this (using the appropriate paths): "[..]\setup.exe" /config ProPlus /config "[..]\Install1stUse-to-Forced.xml" According to the log file, the syntax appears to be accepted and the config file parsed: Parsing command line. Config XML file specified: [..]\Install1stUse-to-Forced.xml Modify requested for product: PROPLUS Parsing config.xml at: [..]\Install1stUse-to-Forced.xml Preferred product specified in config.xml to be: PROPLUS But the "Final Option Tree" still reads: Final Option Tree: AlwaysInstalled:local Gimme_OnDemandData:local ProductFiles:local VSCommonPIAHidden:local dummy_MSCOMCTL_PIA:local dummy_Office_PIA:local ACCESSFiles:local ... AccessWizards:advertised DeveloperWizards:advertised ... And the components remain "Advertised". Just to see if the installation state is overridden in another XML file, I ran: findstr /l /s /i "AccessWizards" *.xml Against both my installation source and "%ProgramFiles%\Common Files\Microsoft Shared\OFFICE12\Office Setup Controller", but just found DefaultState to be "Local". What am I doing wrong? Thanks!

• Very uneven CPU utilization with SQL Server 2012 on 2 processor computer with 16 cores / processor

  - by cooplarsh

  After installing SQL Server Enterprise 2012 with the Server + Cal license model, on a computer with 2 processors each with 16 cores (and no hyperthreading involved) and putting the server under extremely heavy load the 16 cores on the first processor were very underutilized, the first 4 cores on the 2nd CPU were heavily utilized, and the last 12 cores were not used at all (because of the 20 core limit for this sql server version). Total CPU utilization was displaying as around 25%. Unfortunately, the server suffered from extremely poor performance even though if the tasks were evenly distributed across the 20 cores it wouldn't have been anywhere near as bad. The Windows Server was running on a VMWare virtual image under ESX Server, but all of the CPU was allocated to the windows server. We tried changing affinity settings (e.g., allocating most cores to CPU and the others to I/O), but that didn't help solve the performance problems. Upgrading the product edition to SQL Server Enterprise Core 2012 not only allowed the SQL Server to utilize the 12 previously unused cores on the 2nd processor, but it also resulted in a much more even distribution of tasks across all of the processors. To get through the backlog of requests cpU utilization jumped to around 90%, and then came down to around 33% once it was caught up, but performance improved dramatically since we failed over to the newly updated version And the performance issues went away. I was wondering if anyone knows what might cause SQL Server to unevenly distribute the load, relying almost exclusively on the first 4 cores of the 2nd processor that had 12 cores idle, and allocate only a few tasks to each of the 16 cores on the first processor. Also, is there any way we could have more evenly distributed the load across the 20 cores that were being used without the product edition upgrade? The flip side of that question is what did the product upgrade do that caused SQL Server to start evenly distributing the load across all of the cores that it recognized? Thanks to any insight to answer these questions and/or links that might help me better understand how to make sense of what was happenings.

• Java web app deployment and ControlTier adoption

  - by Ran

  I've been searching for a configuration and deployment manager tool for my java-linux based web service and have been looking mainly at ControlTier (http://controltier.org). We operate at a medium scale (100's of hosts, multi-DC, dozens of services). There seem to be be plenty of lower level system admin tools such as chef, puppet, cfengine, bcfg2 and more and my understanding and the reason I'm calling them "low level" is that they are great for system level administration tasks such as setting up a mount, file permissions, users etc but aren't designed, for example for java deployments, which usually come with a build process and special java semantics. In many cases any tool can be used to do anything but if it was not designed for the task it can get uncomfortable. OTOH control-tier seem to have been designed just for that - java application deployments, at least that's what all the tutorials on their site demonstrate but here's the problem - The wiki at http://controltier.org/wiki/ is pretty good and stuffed with examples and the company behind the open source CT product is very responsive (pushy...) however, I'm yet to have seen any material from 3rd party users on the net. No success stories, no detailed blog posts, no best practices, no cheat sheets, not even hate letters, nothing. This plays badly for DTO solutions, CT's sponsor for two reasons, one is that it makes me suspicious what's the reason for the poor adoption? and second, what do I do if I get stuck and there's no help page on CT's wiki page and the mailing list is too slow to answer. I'm stuck with a "free" product that a consultancy company is pushing. So my question here - I'd be interested in hearing if anyone has had real world experience with CT for java based web app deployments and if he'd thumb up the product? Any other comments that may enlighten me are welcome of course...

• Question About mk-table-checksum Results

  - by stevenmusumeche

  Hello, I have 1 master and 2 slaves. I am using MySQL 5.1.42 on all servers. I am attempting to use mk-table-checksum to verify that their data is in sync, but I am getting unexpected results on one of the slaves. First, I generate the checksums on the master like this: mk-table-checksum h=localhost --databases MYDB --tables {$table_list} --replicate=MYDB.mk_checksum --chunk-size=10M My understanding is that this runs the checksum queries on the master which then propagate via normal replication to the slaves. So, no locking is needed because the slaves will be at the same logical point in time when they run the checksum queries on themselves. Is this correct? Next, to verify that the checksums match, I run this on the master: mk-table-checksum --databases MYDB --replicate=IRC.mk_checksum --replicate-check 1 h=localhost,u=maatkit,p=xxxx If there are any differences, I repair the slaves like this: mk-table-sync --execute --verbose --replicate IRC.mk_checksum h=localhost,u=maatkit,p=xxxx After doing all of this, I repaired both slaves with mk-table-sync. However, everytime I run this sequence (after everything has already been repaired), one slave is perfectly in sync but one slave always has a few tables out of sync. I am 99.999% sure that the data on the slaves matches, since I repaired everything and the tables were not even updated on the master between runs of the checksum script. What would cause a few tables to always show out of sync on only one of the slaves? I am stuck. Here is the output: Differences on h=x.x.x.x,p=...,u=maatkit DB TBL CHUNK CNT_DIFF CRC_DIFF BOUNDARIES IRC product 10 0 1 product_id = 147377 AND product_id < 162085 IRC post_order_survey 0 0 1 1=1 IRC mk_heartbeat 0 0 1 1=1 IRC mailing_list 0 0 1 1=1 IRC honey_pot_log 0 0 1 1=1 IRC product 12 0 1 product_id = 176793 AND product_id < 191501 IRC product 18 0 1 product_id = 265041 IRC orders 26 0 1 order_id = 694472 IRC orders_product 6 0 1 op_id = 935375

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by indyvoyage

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• Restoring Windows 2008 Server X86 and X64

  - by rihatum

  Restoring Windows 2008 Server (Domain Controller) We are using Backup Exec System Recovery 2010 to Image our DC. Now this software has a feature to convert the backup into a vmware or hyper-v VM I have also used disk2vhd to convert one of our dc's to a vhd and when I connected it into Hyper-V, it booted fine, I can login - BUT :-) As soon as I login, I get the activation error, that change product key, this product key isn't good for this machine etc. Question is : When in a real recovery situation, what would be the procedure to restore it either virtual or onto a physical box but be able to login and change product key etc ? In this scenario its just locked down and I cant' do anything, if this is the case, how would I replicate my production environment via these tools ? Any Ideas ? Will be grateful for some real world examples here. Same thing happens with our exchange backup / test restore either physical or virtual, can login but nothing else. Now we don't have the keys as they are OEM keys and just wondering what will happen in a real scenario, would we be purchasing another KEY or using the OEM key on our new server ? This is a test environment I am trying to create by restoring our backups either into hyper-v or physical test machines. Also, If I build up a machine (Server 2008) in a VM (Hyper-V), How can I restore just the system state backup of my DC into it ? will that give me the activation error too ? even though I would use the TRIAL ISOs provided by Microsoft ? Kind regards

• Outlook VBA script - find and replace text with image

  I have a e-commerce store. When I get a sale, I receive an order confirmation email which contains the name of the product sold. When the email comes through, I would like to run a script that replaces the product name eg. "red widget", with a picture of that product. Is that possible? I have found a similar code to replace text (set of numbers in this case) with a link, but I need it to replace with a picture instead.

• Correct MySQL username/password, but getting Access Denied error when run from script

  - by Nick

  I'm currently trying to run the following command from within a shell script. /usr/bin/mysql -u username -ppassword -h localhost database It works perfectly fine when executed manually, and not from within a script. When I try to execute a script that contains that command, I get the following error: ERROR 1045 (28000) at line 3: Access denied for user 'username'@'localhost' (using password: YES) I literally copied and pasted the working command into the script. Why the error? As a sidenote: the ultimate intent is to run the script with cron. EDIT: Here is a stripped down version of my script that I'm trying to run. You can ignore most of it up until the point where it connects to MySQL around line 19. #!/bin/sh #Run download script to download product data cd /home/dir/Scripts/Linux /bin/sh script1.sh #Run import script to import product data to MySQL cd /home/dir/Mysql /bin/sh script2.sh #Download inventory stats spreadsheet and rename it cd /home/dir /usr/bin/wget http://www.url.com/file1.txt mv file1.txt sheet1.csv #Remove existing export spreadsheet rm /tmp/sheet2.csv #Run MySQL queries in "here document" format /usr/bin/mysql -u username -ppassword -h localhost database << EOF --Drop old inventory stats table truncate table table_name1; --Load new inventory stats into table Load data local infile '/home/dir/sheet1.csv' into table table_name1 fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; --MySQL queries to combine product data and inventory stats here --Export combined data in spreadsheet format group by p.value into outfile '/tmp/sheet2.csv' fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; EOF EDIT 2: After some more testing, the issue is with the << EOF that is at the end of the command. This is there for the "here document". When removed, the command works fine. The problem is that I need << EOF there so that the MySQL queries will run.
