It's particularly annoying when you accidentally search for "> exit" and the IDE quits (I knew there was a line in the code that was something like *if(counter > exitCount)* so entered that search without thinking).

It needs to go from point A to point B, point B to point C and finally point C to point D. You need it to get there in five days for the least amount of money possible. There are three possible shippers for each leg, each with their own different time and cost for each leg:
Array

(

How would you go about finding the best combination programmatically?
My best attempt so far (third or fourth algorithm) is:
1. Find the longest shipper for each leg
2. Eliminate the most "expensive" one
3. Find the cheapest shipper for each leg
4. Calculate the total cost & days
5. If days are acceptable, finish, else, goto 1
Quickly mocked-up in PHP (note that the test array below works swimmingly, but if you try it with the test array from above, it does not find the correct combination):
$shippers["leg1"] = array(
"UPS" => array("days" => 1, "cost" => 4000),
"Conway" => array("days" => 3, "cost" => 3200),
"FedEx" => array("days" => 8, "cost" => 1000)
);
$shippers["leg2"] = array(
"UPS" => array("days" => 1, "cost" => 3500),
"Conway" => array("days" => 2, "cost" => 2800),
"FedEx" => array("days" => 4, "cost" => 900)
);
$shippers["leg3"] = array(
"UPS" => array("days" => 1, "cost" => 3500),
"Conway" => array("days" => 2, "cost" => 2800),

Say you have a shipment. It needs to go from point A to point B, point B to point C and finally point C to point D. You need it to get there in five days for the least amount of money possible. There are three possible shippers for each leg, each with their own different time and cost for each leg:
Array
(
[leg0] => Array
(
[UPS] => Array
(
[days] => 1
[cost] => 5000
)
[FedEx] => Array
(
[days] => 2
[cost] => 3000
)
[Conway] => Array
(
[days] => 5
[cost] => 1000
)
)
[leg1] => Array
(
[UPS] => Array
(
[days] => 1
[cost] => 3000
)
[FedEx] => Array
(
[days] => 2
[cost] => 3000
)
[Conway] => Array
(
[days] => 3
[cost] => 1000
)
)
[leg2] => Array
(
[UPS] => Array
(
[days] => 1
[cost] => 4000
)
[FedEx] => Array
(
[days] => 1
[cost] => 3000
)
[Conway] => Array
(
[days] => 2
[cost] => 5000
)
)
)
How would you go about finding the best combination programmatically?
My best attempt so far (third or fourth algorithm) is:
1. Find the longest shipper for each leg
2. Eliminate the most "expensive" one
3. Find the cheapest shipper for each leg
4. Calculate the total cost & days
5. If days are acceptable, finish, else, goto 1
Quickly mocked-up in PHP (note that the test array below works swimmingly, but if you try it with the test array from above, it does not find the correct combination):
$shippers["leg1"] = array(
"UPS" => array("days" => 1, "cost" => 4000),
"Conway" => array("days" => 3, "cost" => 3200),
"FedEx" => array("days" => 8, "cost" => 1000)
);
$shippers["leg2"] = array(
"UPS" => array("days" => 1, "cost" => 3500),
"Conway" => array("days" => 2, "cost" => 2800),
"FedEx" => array("days" => 4, "cost" => 900)
);
$shippers["leg3"] = array(
"UPS" => array("days" => 1, "cost" => 3500),
"Conway" => array("days" => 2, "cost" => 2800),
"FedEx" => array("days" => 4, "cost" => 900)
);
$times = 0;
$totalDays = 9999999;
print "<h1>Shippers to Choose From:</h1><pre>";
print_r($shippers);
print "</pre><br />";
while($totalDays > $maxDays && $times < 500){
$totalDays = 0;
$times++;
$worstShipper = null;
$longestShippers = null;
$cheapestShippers = null;
foreach($shippers as $legName => $leg){
//find longest shipment for each leg (in terms of days)

}
}
}
}

Currently, that's pretty much the situation my group faces. We do web-app development primarily (but no desktop development at this time). Software deployments are ugly and unwieldy even with our modest apps, and we've had far too many issues crop up in the two years I have been a part of this team (and company). It's past time to do something about that, and the upshot is that we'll be able to kill two Joel Test birds with one stone (daily builds and one-step builds, neither of which exists in any form whatsoever).
What I'm after here is some general insight on the kinds of things I need to be doing or thinking about, from people who have been in software development for longer than I have and also have bigger brains. I'm confident that will be most of the people currently posting in the beta.
Relevant Tools:
Visual Build
Source Safe 6.0 (I know, but I can't do anything about whether or not we use Source Safe at this time. That might be the next battle I fight.)
Tentatively, I've got a Visual Build project that does this:
1. Get source and place in local directory, including necessary DLLs needed for project.
2. Get config files and rename as needed (we're storing them in a special sub directory that isn't part of the actual application, and they are named according to use).
3. Build using Visual Studio
4. Precompile using command line, copying into what will be a "build" directory
5. Copy to destination.
6. Get any necessary additional resources - mostly things like documents, images, and reports that are associated with the project (and put into directory from step 5). There's a lot of this stuff, and I didn't want to include it previously. However, I'm going to only copy changed items, so maybe it's irrelevant. I wasn't sure whether I really wanted to include this stuff in earlier steps.
I still need to coax some logging out of Visual Build for all of this, but I'm not at a point where I need to do that yet.
Does anyone have any advice or suggestions to make? We're not currently using a Deployment Project, I'll note. It would remove some of the steps necessary in this build I presume (like web.config swapping).

I'm on a machine with 3GB Ram. TaskManager shows the devenv.exe working set to be 578060K, and the entire memory allocation for the machine is 1.78GB. It should have more than enough ram to generate the resources.

None of these boxes are especially critical and they're all using RAID. To date, I've therefore been doing backups of the boxes by having a cron job upload tarballs containing the contents of /etc, MySQL dumps and other such changing, non-packaged data to a box at our geographically separate hosting centre.
I've realised, however that
* the tarballs are sufficient to rebuild from, but it's certainly not a painless process to do so (I recently tried this out as part of a hardware upgrade of one of the boxes)
* long-term, the process isn't sustainable. Each of the boxes is currently producing a tarball of a couple of hundred MB each day, 99% of which is the same as the previous day
* partly due to the size issue, the backup process requires more manual intervention than I want (to find whatever 5GB file is inflating the size of the tarball and kill it)
* again due to the size issue, I'm leaving stuff out which it would be nice to include - the contents of users' home directories, for example. There's almost nothing of value there that isn't in source control (and these aren't our main dev boxes), but it would be nice to keep them anyway.
* there must be a better way
So, my question is, how should I be doing this properly? The requirements are:
* needs to be an offsite backup (one of the main things I'm doing here is protecting against fire/whatever)
* should require as little manual intervention as possible (I'm lazy, and box-herding isn't my main job)
* should continue to scale with a couple more boxes, slightly more data, etc.
* preferably free/open source (cost isn't the issue, but especially for backups, openness seems like a good thing)
* an option to produce some kind of DVD/Blu-Ray/whatever backup from time to time wouldn't be bad
My first thought was that this kind of incremental backup was what tar was created for - create a tar file once each month, add incrementally to it. rsync results to remote box. But others probably have better suggestions.

It appears that the pointer you get back from new[] is not always the same as the address you pass in (5.3.4, note 12 in the standard seems to confirm that this is correct), but I don't see how you can allocate a buffer for the array to go in if this is the case.
The following example shows the problem. Compiled with Visual Studio, this example results in memory corruption:
#include <new>
#include <stdio.h>
class A
{
public:
A() : data(0) {}
virtual ~A() {}
int data;
};
int main(int argc, char* argv[])
{
const int NUMELEMENTS=20;
char *pBuffer = new char[NUMELEMENTS*sizeof(A)];
A *pA = new(pBuffer) A[NUMELEMENTS];
// With VC++, pA will be four bytes higher than pBuffer
printf("Buffer address: %x, Array address: %x\n", pBuffer, pA);
// Debug runtime will assert here due to heap corruption
delete[] pBuffer;
return 0;
}
Looking at the memory, the compiler seems to be using the first four bytes of the buffer to store a count of the number of items in it. This means that because the buffer is only <code>sizeof(A)*NUMELEMENTS</code> big, the last element in the array is written into unallocated heap.
So the question is can you find out how much additional overhead your implementation wants in order to use placement new[] safely? Ideally, I need a technique that's portable between different compilers. Note that, at least in VC's case, the overhead seems to differ for different classes. For instance, if I remove the virtual destructor in the example, the address returned from new[] is the same as the address I pass in. | c++ | null | null | null | null | null | open | Can placement new for arrays be used in a portable way?

I am aware that Microsoft has a rule of thumb stating that a SSRS report should take no longer than 30 seconds to execute. However sometimes gargantuan reports are a preferred evil due to external forces such complying with state laws.
At my place of employment, we have an asp.net (2.0) app that we have migrated from Crystal Reports to SSRS. Due to the large user base and complex reporting UI requirements we have a set of screens that accepts user inputted parameters and creates schedules to be run over night. Since the application supports multiple reporting frameworks we do not use the scheduling/snapshot facilities of SSRS. All of the reports in the system are generated by a scheduled console app which takes user entered parameters and generates the reports with the corresponding reporting solutions the reports were created with. In the case of SSRS reports, the console app generates the SSRS reports and exports them as PDFs via the SSRS web service API.
So far SSRS has been much easier to deal with than Crystal with the exception of a certain 25,000 page report that we have recently converted from crystal reports to SSRS. The SSRS server is a 64bit 2003 server with 32 gigs of ram running SSRS 2005. All of our smaller reports work fantastically, but we are having trouble with our larger reports such as this one. Unfortunately, we can't seem to generate the aforemention report through the web service API. The following error occurs roughly 30-35 minutes into the generation/export:
Exception Message: The underlying connection was closed: An unexpected error occurred on a receive.
The web service call is something I'm sure you all have seen before:
data = rs.Render(this.ReportPath, this.ExportFormat, null, deviceInfo,
selectedParameters, null, null, out encoding, out mimeType, out usedParameters,
out warnings, out streamIds);
The odd thing is that this report will run/render/export if the report is run directly on the reporting server using the report manager. The proc that produces the data for the report runs for about 5 minutes. The report renders in SSRS native format in the browser/viewer after about 12 minutes. Exporting to pdf through the browser/viewer in the report manager takes an additional 55 minutes. This works reliably and it produces a whopping 1.03gb pdf.
Here are some of the more obvious things I've tried to get the report working via the web service API:
- set the HttpRuntime ExecutionTimeout
value to 3 hours on the report
server
- disabled http keep alives on the report server
- increased the script timeout on the report server
- set the report to never time out on the server
- set the report timeout to several hours on the client call
From the tweaks I have tried, I am fairly comfortable saying that any timeout issues have been eliminated.
Based off of my research of the error message, I believe that the web service API does not send chunked responses by default. This means that it tries to send all 1.3gb over the wire in one response. At a certain point, IIS throws in the towel. Unfortunately the API abstracts away web service configuration so I can't seem to find a way to enable response chunking.
1. Does anyone know of anyway to reduce/optimize the PDF export phase and or the size of the PDF without lowering the total page count?
2. Is there a way to turn on response chunking for SSRS?
3. Does anyone else have any other theories as to why this runs on the server but not through the API? | reporting-services | sqlreportingservices | null | null | null | null | open | Optimizing the PDF Export of Huge Reports in Sql Reporting Services 2005

Based off of my research of the error message, I believe that the web service API does not send chunked responses by default. This means that it tries to send all 1.3gb over the wire in one response. At a certain point, IIS throws in the towel. Unfortunately the API abstracts away web service configuration so I can't seem to find a way to enable response chunking.
1. Does anyone know of anyway to reduce/optimize the PDF export phase and or the size of the PDF without lowering the total page count?
2. Is there a way to turn on response chunking for SSRS?
3. Does anyone else have any other theories as to why this runs on the server but not through the API? | 0 |

I have a table with a margin-bottom of 19px. Below that I have a form that contains some fieldsets. One of them is floated right. The problem is that the margin-bottom is not getting the full 19px in IE7. I've gone through all of the IE7 css/margin/float bugs that I can think of and have tried remedies but have been unsuccessful. I have been googling for a while now and cannot find anything that is helping out.
Here is what I have tried.
1. Wrapping the form or fieldset in an unstyled div. No apparent change.
2. Nixing the margin-bottom on the table and instead wrapping that with a div and giving it a padding-bottom of 19px. No apparent change.
3. Nixing the margin-bottom on the table and adding a div with a fixed height of 19px. No apparent change.
I know there are some others that I am forgetting, but those are the things I have tried out recently. This happens to each fieldset.

Scripts will be triggered upon certain events and may stay resident for a period of time. For example upon startup a script may define several options which the program presents to the user as a number of buttons. Upon selecting one of these buttons the program will notify the script where further events may occur.
These are the only real requirements;
1. Must be cross-platform and compilable from source
2. Scripts must be able to call registered code-side functions
3. Code must be able to call script-side functions
4. Be used within a C/C++ codebase.

I recently had a desire to visualize the relationship between [objects][1] in the [Nagios][2] configuration and I realized I didn't know how to do it properly and moved on to something more important. I was reading the responses to [this thread][3] and realized this is something software developers must do a lot.
So this is probably a soft-pitch question, but what is the proper method for documenting object relationships in Visio? Is there a better template to use? What stencil collection is the proper stencil in?
In my probably naive view I imagine an object being a large box with a single "reception" connector and containing multiple smaller boxes, each of which represents an object member and having its own connector. So, each object member field would connect out to the "reception" connector on the object of the member's type. In and of itself those objects are fairly easy to build. The problem I ran into is that the connector lines didn't respect the objects and ran over the top of them, making an awful, unusable mess.
Thanks for any pointers.

And I'm not talking using .NET with a Mono or Wine virtual platform running beneath.
Our company has about 20 developers all running Windows XP/Vista and developing primarily for Linux & Solaris. Until recently we all logged into a main Linux server and modified/built code the good old fashioned way: Emacs, Vi, dtpad - take your pick. Then someone said, "hey - we're living in the Dark Ages, we should be using an IDE".
So we tried out a few and decided that Visual Studio was the only one that would meet our performance needs (yes, I'm sure that IDE X is a very nice IDE, but we chose VS).
The problem is, how do you setup your environment to have the files available locally to VS, but also available to a build server? We settled with writing a Visual Studio plugin - it writes our files locally and to the build server whenever we hit "Save" and we have a bit fat "sync" button that we can push when our files change on the server side (for when we update to the latest files from our source control server).
The plugin also uses Visual Studio's external build system feature that ultimately just ssh's into the build server and calls our local "make" utility (which is Boost Build v2 - has great dependency checking, but is *really* slow to start as a result i.e. 30-60 seconds to begin). The results are piped back into Visual Studio so the developer can click on the error and be taken to the appropriate line of code (quite slick actually). The build server uses GCC and cross-compiles all of our Solaris builds.
But even after we've done all this, I can't help but sigh whenever I start to write code in Visual Studio. I click a file, start typing, and VS chugs to catch up with me.
Is there anything more annoying than having to stop and wait for your tools? Are the benefits worth the frustration?
Thoughts, stories, help?

I see that there's a *.Data.Configuration (or something close to this ... don't recall off the top of my head) assembly but am finding not much on the interwebs. Complicating matters is the fact that the API help is broken on Vista.
Now, I found this work-around:
Configuration cfg = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ConnectionStringSettings connection = new ConnectionStringSettings();
connection.Name = "Runtime Connection";
connection.ProviderName = "System.Data.OleDb";
connection.ConnectionString = "myconstring";
cfg.ConnectionStrings.ConnectionStrings.Add(connection);
cfg.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("connectionStrings");
var runtimeCon = DatabaseFactory.CreateDatabase("Runtime Connection");
And although it gives me what I want, it permanently edits the App.config. Sure I can go back and delete the changes, but I'd rather not go through this hassle.
