• Tell me again why we need both .NET and Windows? Why can't Windows morph into the CLR?

  - by le dorfier

  The same way DOS morphed into Windows? We seem to have ended up supporting and developing for three platforms from Microsoft, and I'm not sure where the boundaries are supposed to lie. Why can't the benefits of the CLR (such as type safety, memory protection, etc.) be built into Windows itself? Or into the browser? Why an entirely other virtual machine? (How may levels of virtual machine indirection are we dealing with now? We just added Silverlight - and before that Flash - running inside the Browser running inside maybe a VM install...) I can see raw Windows for servers, but why couldn't there be a CLR for workstations talking directly to the hardware (or at least not the whole Windows legacy ball and chain)? (ooppp - I've got two questions here. Let's make this - why can't .net be built into Windows? I understand about backward compatibility - but the safety of what's in .NET could be at least optionally in Windows itself, couldn't it? It would just be yet another of many sets of APIs?) Factoid - I recall that one of the competitor architectures selling against MS-DOS on the IBM PC was UCSD-pascal runtime - a VM.

• Change Default Winform Icon Across Entire App

  - by Kyle Gagnet

  Can I change the default icon used on a Winform? Most of my forms have their icon property set to a custom icon. For the few forms that slip through the cracks, I don't want the generic "hey look, he made this in visual studio" icon. One solution is to tediously check every one of my forms to make sure they either have a custom icon set or have ShowIcon set to False. Another solution is to have every one of my forms inherit from a base class that sets a custom icon in the constructor. Aside from those solutions, what other options do I have? EDIT: I was hoping there would be a way to replace the source of the stock icon with my own. Is it in a resource file somewhere? Or is it embedded in a .NET dll that I can't (or really, really shouldn't) modify? BOUNTY EDIT: Is there a way to accomplish this without editing or writing a single line of code? I don't care how impractical, complicated, waste-of-time the solution is... I just want to know if it's possible. I need to satisfy my curiosity.

• Rangy move boundaries of user selection out of header element

  - by Frank

  I'm using rangy and have a case with a contenteditable div where the users selection can be saved and later restored so that HTML can be inserted. My problem is that if the user selects within a header element, I don't want the html inserted within a header. So I'm trying to figure out how to use rangy so that if the the selection is made within a header then I can move it before the header element. So if the user selects within an h1: <div id="editable" contenteditable> <h1>|user selects here| Header Text</h1> </div> Then the saved selection would be moved before the h1: | selection boundary moved here |<div id="editable" contenteditable> <h1>|user selects here| Header Text</h1> </div> I've tried the following to see if I could move the selection boundary: var sel = rangy.getSelection(); var range = sel.getRangeAt(0); range.setStartBefore(sel.anchorNode.parentNode); sel.removeAllRanges(); sel.addRange(range); selected = rangy.saveSelection(); But when I select within the H1, it still sets the saved selection boundaries within the H1 and not before it. I'm not sure how I can get the boundaries moved before the header element.

• Macro not declared in this scope

  - by NmdMystery

  I'm using a preprocessor #define macro to count the number of functions in a header file: #define __INDEX -1 //First group of functions void func1(void); #define __FUNC1_INDEX __INDEX + 1 void func2(void); #define __FUNC2_INDEX __FUNC1_INDEX + 1 #undef __INDEX #define __INDEX __FUNC2_INDEX //Second group of functions void func3(void); #define __FUNC3_INDEX __INDEX + 1 void func4(void); #define __FUNC4_INDEX __FUNC3_INDEX + 1 #undef __INDEX #define __INDEX __FUNC4_INDEX //Third group of functions void func5(void); #define __FUNC5_INDEX __INDEX + 1 void func6(void); #define __FUNC6_INDEX __FUNC5_INDEX + 1 #undef __INDEX #define __INDEX __FUNC6_INDEX #define __NUM_FUNCTIONS __INDEX + 1 The preprocessor gets through the first two sets of functions just fine, but when it reaches the line: #define __FUNC5_INDEX __INDEX + 1 I get a "not defined in this scope" error for __INDEX. What makes this really confusing is the fact that the same exact thing is done [successfully] in the second group of functions; __FUNC3_INDEX takes on the value of __INDEX + 1. There's no typos anywhere, as far as I can tell... what's the problem? I'm using g++ 4.8.

• Another C++ question, delete not working?

  - by kyeana

  New to c++, and am having a problem with delete and destructor (I am sure i am making a stupid mistake here, but haven't been able to figure it out as of yet). When i step through into the destructor, and attepmt to call delete on a pointer, the message shows up "Cannot access memory at address some address." The relevant code is: /* * Removes the front item of the linked list and returns the value stored * in that node. * * TODO - Throws an exception if the list is empty */ std::string LinkedList::RemoveFront() { LinkedListNode *n = pHead->GetNext(); // the node we are removing std::string rtnData = n->GetData(); // the data to return // un-hook the node from the linked list pHead->SetNext(n->GetNext()); n->GetNext()->SetPrev(pHead); // delete the node delete n; n=0; size--; return rtnData; } and /* * Destructor for a linked node. * * Deletes all the dynamically allocated memory, and sets those pointers to 0. */ LinkedListNode::~LinkedListNode() { delete pNext; // This is where the error pops up delete pPrev; pNext=0; pPrev=0; }

• Returning a dynamically created array from function

  - by informer2000

  I'm trying to create a function that would dynamically allocate an array, sets the values of the elements, and returns the size of the array. The array variable is a pointer that is declared outside the function and passed as a parameter. Here is the code: #include <cstdlib> #include <iostream> using namespace std; int doArray(int *arr) { int sz = 10; arr = (int*) malloc(sizeof(int) * sz); for (int i=0; i<sz; i++) { arr[i] = i * 5; } return sz; } int main(int argc, char *argv[]) { int *arr = NULL; int size = doArray(arr); for (int i=0; i<size; i++) { cout << arr[i] << endl; } return 0; } For some reason, the program terminates on the first iteration of the for loop in main()! Am I doing something wrong?

• getting duplicate array output - java

  - by dowln

  Hello, Can someone could be kind and help me out here. Thanks in advance... My code below outputs the string as duplicates. I don't want to use Sets or ArrayList. I am using java.util.Random. I am trying to write a code that checks if string has already been randomly outputted and if it does, then it won't display. Where I am going wrong and how do I fix this. public class Worldcountries { private static Random nums = new Random(); private static String[] countries = { "America", "Candada", "Chile", "Argentina" }; public static int Dice() { return (generator.nums.nextInt(6) + 1); } public String randomCounties() { String aTemp = " "; int numOfTimes = Dice(); int dup = 0; for(int i=0 ; i<numOfTimes; i++) { // I think it's in the if statement where I am going wrong. if (!countries[i].equals(countries[i])) { i = i + 1; } else { dup--; } // and maybe here aTemp = aTemp + countries[nums.nextInt(countries.length)]; aTemp = aTemp + ","; } return aTemp; } } So the output I am getting (randomly) is, "America, America, Chile" when it should be "America, Chile".

• Catch test case order [on hold]

  - by DeadMG

  Can I guarantee the order of execution with multiple TEST_CASEs with Catch? I am testing some code using LLVM, and they have some despicable global state that I need to explicitly initialize. Right now I have one test case that's like this: TEST_CASE("", "") { // Initialize really shitty LLVM global variables. llvm::InitializeAllTargets(); llvm::InitializeAllTargetMCs(); llvm::InitializeAllAsmPrinters(); llvm::InitializeNativeTarget(); llvm::InitializeAllAsmParsers(); // Some per-test setup I can make into its own function CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile(...)); CHECK_NOTHROW(Compile...)); CHECK_NOTHROW(Interpret(...)); CHECK_THROWS(Compile(...)); CHECK_THROWS(Compile(...)); } What I want is to refactor it into three TEST_CASE, one for tests that should pass compilation, one for tests that should fail, and -one for tests that should pass interpretation (and in the future, further such divisions, perhaps). But I can't simply move the test contents into another TEST_CASE because if that TEST_CASE is called before the one that sets up the inconvenient globals, then they won't be initialized and the testing will spuriously fail.

• XenServer 6.0.2 path to installation media contains non-ascii characters

  - by cmaduro

  XenServer 6.0.2 install fails no matter what I do. I have confirmed that the md5 checksum on my ISO file is good. I tried installing from a mounted ISO file (remotely via iKVM). I tried installing from physical media. I tried installing from a bootable USB stick (using syslinux + contents of the ISO) All attempts have yielded the same result: When verifying the installation media, at 0% initializing, the following is reported: "Some packages appeared to be damaged." followed by a list of pretty much all the gz2 and rpm packages. If I skip the media verification the installer proceeds and then gives me an error when it reaches "Installing from base pack" at 0% which states "An unrecoverable error has occurred. The error was: 'ascii' codec can't decode byte 0xff in position 20710: ordinal not in range(128) Please refer to your user guide, or contact a Technical Support Representative, for further details" there is one option left which is to reboot. Apparently at some point during the processing of the repositories on the installation media non-ascii characters are found, which causes the installer to quit. How do I fix this? Here are my specs TYAN S8236 motherboard 2 AMD Opteron 6234 processors LSI2008 card connected to 2 1TB Seagate Constellation drives SATA, 1 500GB Corsair m4 SSD SATA and 1 Corsair Forse 3 - 64GB SSD SATA Onboard SATA connected to a slim DVD-+RW.

The error message appears around line 359. – cmaduro 2 hours ago I am fairly sure that the install error is generated somewhere in repository.py as the backend.py file throws errors while methods in that file are being called. Perhaps all errors can be traced back to this file. – cmaduro 1 hour ago

• Varnish configuration to only cache for non-logged in users

  - by davidsmalley

  I have a Ruby on Rails application fronted by varnish+nginx. As most of the sites content is static unless you are a logged in user, I want to cache the site heavily with varnish when a user is logged out but only to cache static assets when they are logged in. When a user is logged in they will have the cookie 'user_credentials' present in their Cookie: header, in addition I need to skip caching on /login and /sessions in order that a user can get their 'user_credentials' cookie in the first place. Rails by default does not set a cache friendly Cache-control header, but my application sets a "public,s-max-age=60" header when a user is not logged in. Nginx is set to return 'far future' expires headers for all static assets. The configuration I have at the moment is totally bypassing the cache for everything when logged in, including static assets — and is returning cache MISS for everything when logged out. I've spent hours going around in circles and here is my current default.vcl director rails_director round-robin { { .backend = { .host = "xxx.xxx.xxx.xxx"; .port = "http"; .probe = { .url = "/lbcheck/lbuptest"; .timeout = 0.3 s; .window = 8; .threshold = 3; } } } } sub vcl_recv { if (req.url ~ "^/login") { pipe; } if (req.url ~ "^/sessions") { pipe; } # The regex used here matches the standard rails cache buster urls # e.g. /images/an-image.png?1234567 if (req.url ~ "\.(css|js|jpg|jpeg|gif|ico|png)\??\d*$") { unset req.http.cookie; lookup; } else { if (req.http.cookie ~ "user_credentials") { pipe; } } # Only cache GET and HEAD requests if (req.request != "GET" && req.request != "HEAD") { pipe; } } sub vcl_fetch { if (req.url ~ "^/login") { pass; } if (req.url ~ "^/sessions") { pass; } if (req.http.cookie ~ "user_credentials") { pass; } else { unset req.http.Set-Cookie; } # cache CSS and JS files if (req.url ~ "\.(css|js|jpg|jpeg|gif|ico|png)\??\d*$") { unset req.http.Set-Cookie; } if (obj.status >=400 && obj.status <500) { error 404 "File not found"; } if (obj.status >=500 && obj.status <600) { error 503 "File is Temporarily Unavailable"; } } sub vcl_deliver { if (obj.hits > 0) { set resp.http.X-Cache = "HIT"; } else { set resp.http.X-Cache = "MISS"; } }

• Having trouble Getting "RTSP over HTTP"

  - by Muhammad Adeel Zahid

  There is an axis camera that is connected to our site (camba.tv) through axis one click connection component (which acts as proxy). We can communicate with this camera only through http by setting the proxy to our OCCC server's address. If we want to get RTSP streams (h.264) we are only left with "RTSP over HTTP" option. For this I have followed axis VAPIX 3 documentation section 3.3. I issue requests through fiddler but don't get any response. But when i put the URL (axrtsphttp://1.00408CBEA38B/axis-media/media.amp) in windows media player (with proxy set to OCCC server 212.78.237.156:3128) the player is able to get RTSP stream over HTTP after logging in. I have created a request trace of communication between camera and windows media player through wireshark and the request that brings the stream looks like http://1.00408cbea38b/axis-media/media.amp HTTP/1.1 x-sessioncookie: 619 User-Agent: Axis AMC Host: 1.00408CBEA38B Proxy-Connection: Keep-Alive Pragma: no-cache Authorization: Digest username="root",realm="AXIS_00408CBEA38B",nonce="000a8b40Y0100409c13ac7e6cceb069289041d8feb1691",uri="/axis-media/media.amp",cnonce="9946e2582bd590418c9b70e1b17956c7",nc=00000001,response="f3cab86fc84bfe33719675848e7fdc0a",qop="auth" HTTP/1.0 200 OK Content-Type: application/x-rtsp-tunnelled Date: Tue, 02 Nov 2010 11:45:23 GMT RTSP/1.0 200 OK CSeq: 1 Content-Type: application/sdp Content-Base: rtsp://1.00408CBEA38B/axis-media/media.amp/ Date: Tue, 02 Nov 2010 11:45:23 GMT Content-Length: 410 v=0 o=- 1288698323798001 1288698323798001 IN IP4 1.00408CBEA38B s=Media Presentation e=NONE c=IN IP4 0.0.0.0 b=AS:50000 t=0 0 a=control:* a=range:npt=0.000000- m=video 0 RTP/AVP 96 b=AS:50000 a=framerate:30.0 a=transform:1,0,0;0,1,0;0,0,1 a=control:trackID=1 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1; profile-level-id=420029; sprop-parameter-sets=Z0IAKeNQFAe2AtwEBAaQeJEV,aM48gA== RTSP/1.0 200 OK CSeq: 2 Session: 3F4763D8; timeout=60 Transport: RTP/AVP/TCP;unicast;interleaved=0-1;ssrc=060922C6;mode="PLAY" Date: Tue, 02 Nov 2010 11:45:24 GMT RTSP/1.0 200 OK CSeq: 3 Session: 3F4763D8 Range: npt=0- RTP-Info: url=rtsp://1.00408CBEA38B/axis-media/media.amp/trackID=1;seq=7392;rtptime=4190934902 Date: Tue, 02 Nov 2010 11:45:24 GMT [Binary Stream Content] But when i copy this request to fiddler, I only get 200 status code with content-type set to application/x-rtsp-tunneled and there is no stream data. The only thing i do different with stream is to use Basic in authorization header instead of Digest and I do not get 401 (Un authorized) status code. Can anyone explain what's happening here? How can I write request sequences to get stream in fiddler? If it is needed, I can upload the wireshark request dump somewhere.

• Slow Memcached: Average 10ms memcached `get`

  - by Chris W.

  We're using Newrelic to measure our Python/Django application performance. Newrelic is reporting that across our system "Memcached" is taking an average of 12ms to respond to commands. Drilling down into the top dozen or so web views (by # of requests) I can see that some Memcache get take up to 30ms; I can't find a single use of Memcache get that returns in less than 10ms. More details on the system architecture: Currently we have four application servers each of which has a memcached member. All four memcached members participate in a memcache cluster. We're running on a cloud hosting provider and all traffic is running across the "internal" network (via "internal" IPs) When I ping from one application server to another the responses are in ~0.5ms Isn't 10ms a slow response time for Memcached? As far as I understand if you think "Memcache is too slow" then "you're doing it wrong". So am I doing it wrong? Here's the output of the memcache-top command: memcache-top v0.7 (default port: 11211, color: on, refresh: 3 seconds) INSTANCE USAGE HIT % CONN TIME EVICT/s GETS/s SETS/s READ/s WRITE/s cache1:11211 37.1% 62.7% 10 5.3ms 0.0 73 9 3958 84.6K cache2:11211 42.4% 60.8% 11 4.4ms 0.0 46 12 3848 62.2K cache3:11211 37.5% 66.5% 12 4.2ms 0.0 75 17 6056 170.4K AVERAGE: 39.0% 63.3% 11 4.6ms 0.0 64 13 4620 105.7K TOTAL: 0.1GB/ 0.4GB 33 13.9ms 0.0 193 38 13.5K 317.2K (ctrl-c to quit.) ** Here is the output of the top command on one machine: ** (Roughly the same on all cluster machines.

• Can someone explain RAID-0 in plain English?

  - by Edward Tanguay

  I've heard about and read about RAID throughout the years and understand it theoretically as a way to help e.g. server PCs reduce the chance of data loss, but now I am buying a new PC which I want to be as fast as possible and have learned that having two drives can considerably increase the perceived performance of your machine. In the question Recommendations for hard drive performance boost, the author says he is going to RAID-0 two 7200 RPM drives together. What does this mean in practical terms for me with Windows 7 installed, e.g. can I buy two drives, go into the device manager and "raid-0 them together"? I am not a network administrator or a hardware guy, I'm just a developer who is going to have a computer store build me a super fast machine next week. I can read the wikipedia page on RAID but it is just way too many trees and not enough forest to help me build a faster PC: RAID-0: "Striped set without parity" or "Striping". Provides improved performance and additional storage but no redundancy or fault tolerance. Because there is no redundancy, this level is not actually a Redundant Array of Inexpensive Disks, i.e. not true RAID. However, because of the similarities to RAID (especially the need for a controller to distribute data across multiple disks), simple strip sets are normally referred to as RAID 0. Any disk failure destroys the array, which has greater consequences with more disks in the array (at a minimum, catastrophic data loss is twice as severe compared to single drives without RAID). A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the array. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, increasing bandwidth. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss. So in plain English, how can "RAID-0" help me build a faster Windows-7 PC that I am going to order next week?

  I'm trying to figure out what the best possible processor is that I can stick in my HP MediaSmart server. I'm clueless when it comes to correlating CPUs to motherboards. I suspect it's the socket type I care about, but I worry that there's more to it.

• Windows 7 file-based backup service

  - by Ben Voigt

  I'm looking for a good replacement for Lazy Mirror, since it doesn't support Windows 7 well. Pros: One of the things I really loved about Lazy Mirror is that it always maintains a "full" backup, but does so by only copying modified files. As each file was copied, the old version got archived (moved to an out-of-the-way location). So after mirroring ran, there'd be a complete copy of the file system, which could even be booted if necessary. At the same time, extra space on the backup media was used to store as many older versions of files as possible, without wasting space storing multiple copies of the same version. It seems that with Windows 7 backup, there'd be wasted space storing the same data in both the system image and file backup. It was completely file-based, but also aware of the registry (it had a feature to dump the live registry to hive files in the correct format). The backups were normal NTFS filesystems, no special tool was needed to read them. It automatically cleaned out the oldest previous versions when space ran out (unlike Windows 7 backup which apparently simply starts failing the the backup media fills.) It copied all file attributes including security. Cons: It doesn't deal well with junction points, symbolic links, and hard links. It didn't run as a service without lots of help from firesrv or srvany, and then you couldn't interact with the GUI. Running as a service was necessary to be able to mirror protected OS files. It didn't have open file handling, except for registry hives. I guess that the file-by-file archive and replacement could leave mismatched sets of files, if the mirror was interrupted. This would be the advantage of incremental backup techniques that require old full backup + all intermediate incremental backups to restore. But I don't see this as presenting much of a problem, you'd really only have a boot failure if you had a mixture of pre- and post-service pack files, and I can run a full image backup using another tool before applying a service pack. Does anyone know of a tool that does both full-system backup and storage of old versions of files like Lazy Mirror did (without storing the same data multiple times), and also can run as a service in Windows 7? Free is best of course, but a reasonably priced paid program (e.g. It would be absolutely awesome if it also triggered a backup/mirror pass when a particular external drive was plugged in and generated popup warnings if backups hadn't been run recently)

• Blank displays after inactivity, mouse cursor not showing up

  - by Mike Christiansen

  I have a Windows 7 Enterprise x86 machine that is exhibiting some strange problems. After some inactivity (it varies how long it takes), when I come back to my computer, both of my monitors are black. The monitors are on, with a black display. Moving the mouse and pressing keys on the keyboard do not work. This happens at least once a day. When I first encountered the issue, I performed a hard shutdown and restarted the computer. About 10% of the time when I did this, the resolutions on my monitors were messed up. The native resolution on the primary monitor is 1600x900, and the native on my secondary is 1440x900. None of the widescreen resolutions would be present in the display properties. I had 800x600, 1024x768, and 1280x1024. As a workaround to this issue, I've found that if I plug in my secondary monitor as the primary monitor, and leave the secondary unplugged, then Windows will start in 1024x768 on the secondary. Then, I can use Windows 7's "Detect" feature and it finds the 1440x900 resolution, and sets it. Then I have to connect the primary monitor to the secondary port and set it as the primary. Then I can switch the two cables, putting the primary into the primary, the secondary into the secondary. Then use the "Detect" feature again, and it finds the correct resolutions. Some time after performing the above, I discovered that when the screens were blanked, I could simply press "Control+Alt+Delete", type in my password, and everything comes up fine - except my mouse cursor. All applications and features work as intended, except there is no mouse cursor (the mouse actually works though...). I have the "Show location of pointer when I press CTRL key" option selected, so I can press CTRL and use my mouse as normal - but I have no actual cursor. When the computer is in this state, UAC is also not functional. Whenever a UAC prompt appears, the screens go black (the original symptoms) and I have to press Escape to exit UAC. Because of the above symptoms (the UAC black screen thing, etc) I beleive winlogon.exe may be the culprit. However, I have no idea how to fix it. I am unable to restart winlogon.exe due to the problems I am having with winlogon.exe (the UAC black screen) Looking for any ideas.... More information Windows 7 x86 Enterprise Domain environment (I have a secondary account with administrator rights) Dell Optiplex 960 Cannot perform "optional" windows updates due to an activation issue (I am testing a windows 7 image, and an activation infrastructure has not been created yet. However, this issue was happening before I was unable to perform windows update, and windows was up to date at the time Updated video card driver (as an attempt to fixing the resolution issue) Disabled all power saving options Please let me know what else you need to help me solve this issue! Thanks in advance, Mike

• Using curl -s in *nix command line not working for some reason

  I am trying to install composer (though to be honest I really have no idea how it fully works and documentation seems to be quite poor) on my MediaTemple DV machine. I am using their [instructions][1] Trying to install globally using: $ curl -s https://getcomposer.org/installer | php My command line (again using putty and logged into my server as root) thinks for a second, then sets up for next prompt.

• How to make Horde connect to mysql with UTF-8 character set?

  - by jkj

  How to tell horde 3.3.11 to use UTF-8 for it's mysql connection? The $conf['sql']['charset'] only tells horde what is expected from the database. Horde uses MDB2 to connect to mysql. Is there way to force MDB2 or mysql character_set_client from php.ini? So far I found two workarounds: Force mysql to ignore character set requested by client [mysqld] skip-character-set-client-handshake=1 default-character-set=utf8 Force mysql to run SET NAMES utf8 on every connection [mysqld] init-connect='SET NAMES utf8' Both have drawbacks on multi user mysql server. The first disables converting character sets alltogether and the second one forces every connection to produce UTF-8. [EDIT] Found the problem. The 'charset' parameter was unset the last minute before sending to SQL backend. This is probably due to mysql not being able to digest utf-8 but utf8. Mysql specific mapping is required to make it work. I just worked around it by translating utf-8 - utf8. Won't work with any other databases with this patch though. --- lib/Horde/Share/sql.php.orig 2011-07-04 17:09:33.349334890 +0300 +++ lib/Horde/Share/sql.php 2011-07-04 17:11:06.238636462 +0300 @@ -753,7 +753,13 @@ /* Connect to the sql server using the supplied parameters. */ require_once 'MDB2.php'; $params = $this->_params; - unset($params['charset']); + + if ($params['charset'] == 'utf-8') { + $params['charset'] = 'utf8'; + } else { + unset($params['charset']); + } + $this->_write_db = &MDB2::factory($params); if (is_a($this->_write_db, 'PEAR_Error')) { Horde::fatal($this->_write_db, __FILE__, __LINE__); @@ -792,7 +798,13 @@ /* Check if we need to set up the read DB connection seperately. */ if (!empty($this->_params['splitread'])) { $params = array_merge($params, $this->_params['read']); - unset($params['charset']); + + if ($params['charset'] == 'utf-8') { + $params['charset'] = 'utf8'; + } else { + unset($params['charset']); + } + $this->_db = &MDB2::singleton($params); if (is_a($this->_db, 'PEAR_Error')) { Horde::fatal($this->_db, __FILE__, __LINE__);

• Baseline / Benchmark Physical and virtual server performance

  - by EyeonTech

  I am setting up a new server and there are some options. I want to perform some benchmarks and I need your help in determining the best tools and if possible run pre-configured benchmarks designed for SQL servers on Windows Server 2008/2012. Step 1. Run a performance monitor on the current Live SQL server (Windows Server 2008 Virtual machine running on ESXi. New server Hardware rundown: Intel® Server System R1304BTLSHBN - 1U Rack, LGA1155 http://ark.intel.com/products/53559/Intel-Server-System-R1304BTLSHBN Intel Xeon E3-1270V2 2x Intel SSD 330 Series 240GB 2.5in SATA 6Gb/s 25nm 1x WD 2TB WD2002FAEX 2TB 64M SATA3 CAVIAR BLACK 4x 8GB 1333MHz DDR3 ECC CL9 DIMM There are several options for configurations and I want to benchmark some of them and share the results. Option 1. Configure 2x SSDs at RAID 0. Install Windows Server 2008 directly to the 2TB WD Caviar HDD. Store Database files on the RAID 0 Volume. Benchmark the OS direct on the hardware as an SQL Server. Store SQL Backup databases on the 2TB WD Caviar HDD. Option 2. Configure 2x SSDs at RAID 0. Install Windows Server 2012 directly to the 2TB WD Caviar HDD. Install Hyper-V. Install the SQL Server (Server 2008) as a virtual machine. Store the Virtual Hard Disks on the SSDs. Option 3. Configure 2x SSDs at RAID 0. Install VMWare ESXi on a partition of the 2TB WD Caviar HDD. Install the SQL Server (Server 2008) as a virtual machine. Store the Virtual Hard Disks on the SSDs. I have a few tools in mind from http://technet.microsoft.com/en-us/library/cc768530(v=bts.10).aspx. Any tools with pre-configured test would be fantastic. Specifically if there are pre-configured perfmon sets avaliable. Any opinions on the setup to gain the best results is welcome. Thanks in advance.

• apcupsd on Linux does not report on APC BackUPS Pro 900

  - by lserni

  From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64).

If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

• How can I get the Terminal raster font to display alt codes in a text editor?

  - by grg-n-sox

  I am working on a project that includes making some ASCII art, except it isn't true ASCII art since I am using a far amount of Windows Alt codes to make it. Anyways, I wanted to make sure that as I am working on it, that it looks exactly how it will in a windows command prompt terminal session. So since command prompt defaults to the Terminal raster font, I figured I would use that. But I quickly noticed that when I use the Terminal typeface in a text editor, it will not render ASCII codes, either at all (as is the case most of the time) or incorrectly. Now, I understand if a font just doesn't support non-ASCII characters, but what I don't get is how the characters do show up correctly in command prompt when they don't in a text editor. I checked the output of the 'chcp' and it was set to 437 by default, which is what I need. Well, either that or 850 but preferably 437 since they got rid of some of the graphics in 437 and replaced them with other Latin characters. Command prompt terminal settings show I am using the Terminal raster font with a 8x12 glyph size. So I try using size 12 in the text editor but no good, even after switching the text encoding to either MS-DOS OEM-US (supposedly an alternative name for CP437) or UTF-8. I just don't get how I am not getting the characters to show up. Also, if it helps, the art I am making is basically modified screen shots from a game I play called Dwarf Fortress that uses characters from the Terminal/Curses typeset, or at least that is how it is reported in the forums by those who make graphics sets to replace the default character set. However, the game doesn't actually use the system's Terminal font. The game's data files includes a bitmap image that is a grid of all the characters the game uses. So it uses this bitmap to render graphics instead of the actual font file. And I basically want to get a text editor to make it so if I type up some ASCII art to look like a screenshot from Dwarf Fortress, that it will actually look like Dwarf Fortress other than the lack of color. Any help?

• Configure spanning tree from HP to Cisco hardware

  - by Tim Brigham

  I have three switches I'd like to configure in a loop - a Cisco stack (3750s) and two HP 2900 series. Each is connected to the next with a 10 gig backplane of one form or another. How do I configure the spanning tree on these systems to make this function correctly? From the documents I've looked at it looks like I need to set both sets of hardware to use MST mode but I'm not sure past that point. The trunking, etc is all set up as needed.
