• How do I customize what a third party MSM does?

  - by sqlrob

  I'm trying to convert a project in Visual Studio 2008 from static linking of the CRT to dynamic linking. This was easy enough, and I added the CRT MSM and policy MSM to my Wix file with no problems. I am not that happy with the MSI that is output though, it is much larger than what I expected. Looking at the MSI with Orca shows three copies of the CRT DLLs that I need. From looking at the conditions, one of the sets is used for pre-XP installs. Since the system requirements are XP and later, how do I remove this component without touching the original MSM? This needs to be done in an automated build, so Orca isn't a possible solution. Plus, when I tried it with Orca, the filesize remained the same after deleting the File and Component rows. And somewhat related, how do I set the permanent attribute in the components that remain?

• Overtime culture slowly creeping in - How do I handle this?

  - by bobsmith123

  Our company was one of the very few companies that did not enforce overtime. As such, all my team members promptly worked 40-48 hours a week and everything was good. We hired a few new developers and one of them has positioned himself to be a team lead. He has started working overtime, sending emails in the middle of the night which has come somewhat as a shock for the laid back team. Obviously, the higher ups seem to love him for being the "bad guy" enforcing overtime. Before this goes out of control, what steps do I take to stop this from continuing. I would rather not bring this up with the bosses for the fear of being seen as a whining team member. I am not sure if I should reply to his email outside work hours and encourage him to enforce this culture on our team. Thoughts?

• Visual Studio 2010 Formatting

  - by Rosarch

  I have plenty of experience with Eclipse, and now I'm trying out Visual Studio 2010. I find its formatting somewhat counter-intuitive. Here are some things I'm trying to figure out: Is there a way to select all text and format/indent it properly, like SHIFT+A SHIFT+I in Eclipse? Why is it that when I type a line like if (n == 0) {, as soon as I type the opening brace, the text cursor is moved to the beginning of the line? Is this some productivity speedup I'm failing to see? When I hit ENTER after the aforementioned line, I'd like the closing brace to be put in place automatically for me. How can I do this? I've looked for hotkey documentation, and it's helped a bit, but this still feels clunky to me.

• My PowerShell functions do not appear to be registered

  - by Frank

  Hi there, I have a ps1 script in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

• When to use delaycompress option in logrotate?

  - by Anand Chitipothu

  The man page of logrotate says that: It can be used when some program cannot be told to close its logfile and thus might continue writing to the previous log file for some time. I'm confused by this. If a program cannot be told to close its logfile, it will continue to write forever, not for sometime. If the compression is postponed to next rotation cycle, the program continues to write to that file even after the next rotation cycle. How is postponing solving the problem? My understanding is that copytruncate should be used when a program cannot be told to close the logfile. I'm aware that some data written to the logfile gets lost when the copy is in progress. I was looking at the logrotate file for couchdb, and it had both copytruncate and delaycompress options. /usr/local/couchdb-1.0.1/var/log/couchdb/*.log { weekly rotate 10 copytruncate delaycompress compress notifempty missingok } It looks like there is no point using delaycompress when copytruncate is already there. What am I missing?

  - by July

  I installed 7-zip and add its directory to system path: C:\Program Files\7-Zip to PATH, from windows start-input cmd and press enter, Windows command line is started, i type 7z.exe, then press enter, it just run.

I'm on Win7. 2. For some other apps, the above way did works, that's why i'm so confused how bat works.

• Mac Mail.app & Smart Mailbox conditions

  - by Michael Birchall

  Hey Guys, I'm having some trouble with my Smart Mailbox setup. I've got a Smart Mailbox named "Unread". And Contains messages that match any of the following conditions: Message is Unread Message is not in Mailbox News (AT) lovejungle.com Message is not in Mailbox Info (AT) lovejungle.com For some reasons, it is still displaying messages in either News@ or Info@. I've removed either Not in News@ or Info@ and it still shows messages from each inbox. Any ideas on what's set up wrong? :confused: http://i.imgur.com/IHquL.jpg

• How Do You Profile & Optimize CUDA Kernels?

  - by John Dibling

  I am somewhat familiar with the CUDA visual profiler and the occupancy spreadsheet, although I am probably not leveraging them as well as I could. Profiling & optimizing CUDA code is not like profiling & optimizing code that runs on a CPU. So I am hoping to learn from your experiences about how to get the most out of my code. There was a post recently looking for the fastest possible code to identify self numbers, and I provided a CUDA implementation. I'm not satisfied that this code is as fast as it can be, but I'm at a loss as to figure out both what the right questions are and what tool I can get the answers from. How do you identify ways to make your CUDA kernels perform faster?

• jQuery event.layerX/Y is not relative to the element that triggered the event, is that correct?

  - by michielvoo

  If I use for example a mousemove event handler on a div and check the layerX property of the event, it changes when my mouse enters a positioned element inside that div (like an image). According to the jQuery Event object documentation it should follow the W3C DOM Level 3 specifications. But there's no mention of the layerX/Y property for the MouseEvent interface, so I'm wondering what behavior is according to specification? To me it seems that you always want the layerX/Y to be relative to the layer that fires the event, if I wanted the layerX/Y of a nested element, I would check the event in a different phase (bubbling) or would attach my handler to that nested element. My question is (somewhat subjective): how should layerX/Y work?

• SSH + MysqlDump Remote Backup Script

  - by bundini

  I'm trying to issue a remote mysqldump command, redirect stdout to a dmp file, then tar that up. I'm a bit confused as to how to do the redirection bits over ssh: i.e. ssh [email protected] mysqldump $dbname -u admin -p > dbdump.dmp && tar cvzf dbdump.tar.gz dbdump.dmp Issues: 1) I'm not providing the password because I want it to prompt me. Will an ssh remote command deal with this? 2) What's the deal with the syntax? Do I want to use quotations, or don't I? What happens with the redirects and pipes? Do those have to be escaped or formatted in some special fashion.

• File private variables in PHP

  - by kayahr

  Is it possible to define private variables in a PHP script so these variables are only visible in this single PHP script and nowhere else? I want to have an include file which does something without polluting the global namespace. It must work with PHP 5.2 so PHP namespaces are not an option. And no OOP is used here so I'm not searching for private class members. I'm searching for "somewhat-global" variables which are global in the current script but nowhere else. In C I could do it with the static keyword but is there something similar in PHP? Here is a short example of a "common.php" script: $dir = dirname(__FILE__); set_include_path($dir . PATH_SEPARATOR . get_include_path()); // Do more stuff with the $dir variable When I include this file in some script then the $dir variable is visible in all other scripts as well and I don't want that. So how can I prevent this?

• I just got a linode VPS a week ago and I've been flagged for SSH scanning...

  - by meder

  I got a 32-bit Debian VPS from http://linode.com and I really haven't done any sort of advanced configuration for securing it ( port 22; password enabled ). It seems somehow there is ssh scanning going on from my IP, I'm being flagged as this is against the TOS. I've been SSHing only from my home Comcast ISP which I run Linux on. Is this a common thing when getting a new vps? Are there any standard security configuration tips? I'm quite confused as to how my machine has been accused of this ssh scanning.

• Signed and unsigned, and how bit extension works

  - by hatorade

  unsigned short s; s = 0xffff; int i = s; How does the extension work here? 2 larger order bytes are added, but I'm confused whether 1's or 0's are extended there. This is probably platform dependent so let's focus on what Unix does. Would the two bigger order bytes of the int be filled with 1's or 0's, and why? Basically, does the computer know that s is unsigned, and correctly assign 0's to the higher order bits of the int? So i is now 0x0000ffff? Or since ints are default signed in unix does it take the signed bit from s (a 1) and copy that to the higher order bytes?

• How to change the color of the navigation bar in more than one table view controller

  - by Dctennisboy

  I am trying to figure out how to change the color of the table view navigation bar in multiple table views. The table views are all connected to a navigation controller. For example, I want one navigation bar to be blue, but another to be red. I have tried the code below in the AppDelegate.m file, but it just changes all the navigation bars to the same color. Is there anywhere else I could place this code to change the color in specific places. I've heard that I need to create new files, but I don't know where to place the code, or what code to use in the new files. I am somewhat new to this. Any suggestions would be greatly appreciated![[UINavigationBar appearance] setBarTintColor:[UIColor orangeColor]];

• Searching for patterns to create a TCP Connection Pool for high performance messaging

  - by JoeGeeky

  I'm creating a new Client / Server application in C# and expect to have a fairly high rate of connections. That made me think of database connection pools which help mitigate the expense of creating and disposing connections between the client and database. I would like to create a similar capability for my application and haven't been able to find any good examples of how to apply this pattern. Do I really need to spin up an instance of a TcpClient every time I want to send a message to the server and receive a receipt message? Each connection is expected to transport between 1-5KB with each receiving a 1KB response message. I realize this question is somewhat vague, but I am starting from scratch so I am open to suggestions. Even if that means my suppositions are all wrong.

• SVN Best practice for a "branch" of your main product ?

  - by Steffen

  At my job we develop websites - however now we're going to make a "whitelabelled" version of a site, which basically means it's the same site, however with a different logo and hosted on a different domain. Also it'll have minor graphical differences, but overall the engine is the same. My initial thought for keeping this in SVN, was to just make a branch for it - however I'm not quite certain if this could give me trouble later on. Normally I keep my branches somewhat short lived - mainly used for developing a new feature, without disturbing trunk. We need to be able to merge trunk changes into this "whitelabel" version, which I why I thought about branching it in the first place. So what's the best way to archive this ?

• Panic Transmit file upload

  - by 1ndivisible

  I've ditched Coda and bought Transmit. I'm a little confused by the file uploading. I have exactly the same folder structure remotely and locally, but if I right-click a file and choose Upload "SomeFileName.html" The file is always uploaded into the root of the remote site, even if the file is in a folder. If I choose to upload a file at assets/images/some_image.png I would expect it to be uploaded to the same folder on the remote server, not the root. Coda dealt with this perfectly and also told me what files had been modified and needed uploading. Transmit doesn't seem to do either of these things. So my questions are: How can I upload a file to the same path on the remote server without having to drag and drop Is there any way to have Transmit mark edited files or upload only edited files. [There is no tag for Transmit so if someone with more rep could make and add one that would be grand]

• Using Powershell's Invoke-command to install .exe on remote computer

  - by Bernie

  I have an .exe I would like to install on a large farm of Windows Server 2008 computers. I am attempting to use Powershell remoting. I have this command which works locally: invoke-command {& "N:\Temp\fortify_installer\HP-Fortify-3.20-Analyzers_and_Apps-Windows-x86.exe /s /f1N:\Temp\fortify_installer\response.iss"} But when I add the -computername flag it seems to go off to nowhere, and the installer is never run on the remote machine. I can launch notepad.exe via the same command and it runs. Does it have something to do with it being an installer, or something else? I realize many versions of this question have been asked and I have read them, but I am still confused as to why this doesn't work.

• Find the closest vector

  - by Alexey Lebedev

  Hello! Recently I wrote the algorithm to quantize an RGB image. Every pixel is represented by an (R,G,B) vector, and quantization codebook is a couple of 3-dimensional vectors. Every pixel of the image needs to be mapped to (say, "replaced by") the codebook pixel closest in terms of euclidean distance (more exactly, squared euclidean). I did it as follows: class EuclideanMetric(DistanceMetric): def __call__(self, x, y): d = x - y return sqrt(sum(d * d, -1)) class Quantizer(object): def __init__(self, codebook, distanceMetric = EuclideanMetric()): self._codebook = codebook self._distMetric = distanceMetric def quantize(self, imageArray): quantizedRaster = zeros(imageArray.shape) X = quantizedRaster.shape[0] Y = quantizedRaster.shape[1] for i in xrange(0, X): print i for j in xrange(0, Y): dist = self._distMetric(imageArray[i,j], self._codebook) code = argmin(dist) quantizedRaster[i,j] = self._codebook[code] return quantizedRaster ...and it works awfully, almost 800 seconds on my Pentium Core Duo 2.2 GHz, 4 Gigs of memory and an image of 2600*2700 pixels:( Is there a way to somewhat optimize this? Maybe the other algorithm or some Python-specific optimizations.

• How to prevent Artificial Intelligence from escaping into the internet?

  - by Jason

  I have an interest in artificial intelligence from a evolutionary standpoint. I want to experiment with it somewhat with a high level language like C#, however, I'm stuck on one of the most elementary problems with artificial life -- how to contain it? The best thing I can think of is a virtual machine. Where would I start to create a VM for my budding digital organisms in C#? How could I be sure they couldn't escape into the 'wild'? (I understand this unlikely, by the way.)

• How can I pipe a large amount of data as a runtime argument?

  - by Zombies

  Running an executable JAR on a linux platform here. The program it self works on a somewhat large amount of data, basically a list of URLs... could be up to 2k. Currently I get this from a simple DB call. But I was thinking that instead of creating a new mode and writing SQL to get a new result set and having to redploy everytime, I could just make the program more robust by passing in the result set (the list of URLs) that need to be worked on... so, within a linux environment, is there a pain-free/simple way to get the result set and pass it in dynamically? I know file i/o is one, but it doesn't seem to be effecient because each file has to be named, as well more logic to handle grabbing the correct file, creating a file with a unique name, etc.

• Storing script files outside web root

  - by memilanuk

  I've seen recommendations to store some or all php include files some place other than in the web document root directory (username/public_html in my case) for the specific reason of protecting php files with sensitive information (like database connection and login info) in the event that the web server hiccups and stops protecting php files and they become 'visible' to outsiders who know where to look. It seems somewhat paranoid to me, but I'm guessing people have gotten burned badly on this before so I'm willing to go along. The suggestion usually takes the form of having the include files in something like '../include_files/' so its not directly in the document root and not directly accessible to outsiders through the web server. My question is this: is there a significant difference in security between that way and just putting your 'include_files' directory under the document root and sticking an .htaccess file in there (with the appropriate entries)? Would putting an .htaccess file in '../include_files/' make any significant improvement there? TIA, Monte

• Checking whether an object exists in StructureMap container

  - by Kevin Pang

  I'm using StructureMap to handle the creation of NHibernate's ISessionFactory and ISession. I've scoped ISessionFactory as a singleton so that it's only created once for my web app and I've scoped ISession as a hybrid so that it will only be opened once per web request. I want to make sure that at the end of each web request, I properly dispose of ISession if it was created for that web request. I figured I could put some code in my Application_EndRequest routine to first check if an ISession was created, and if so, call ISession.Dispose. My current workaround is to just open up an ISession on Application_BeginRequest then dispose of it on Application_EndRequest, but that seems somewhat wasteful in that static file requests for images and css files and whatnot will create an ISession without ever using it. I know that the overall performance hit is negligable since ISessions are very lightweight, but it's getting annoying seeing all those ISessions being created inside NHProf.

• rsnapshot intervals in configuration file...

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

• How can I calculate data for a boxplot (quartiles, median) in a Rails app on Heroku? (Heroku uses Po

  - by hadees

  I'm trying to calculate the data needed to generate a box plot which means I need to figure out the 1st and 3rd Quartiles along with the median. I have found some solutions for doing it in Postgresql however they seem to depend on either PL/Python or PL/R which it seems like Heroku does not have either enabled for their postgresql databases. In fact I ran "select lanname from pg_language;" and only got back "internal". I also found some code to do it in pure ruby but that seems somewhat inefficient to me. I'm rather new to Box Plots, Postgresql, and Ruby on Rails so I'm open to suggestions on how I should handle this. There is a possibility to have a lot of data which is why I'm concerned with performance however if the solution ends up being too complex I may just do it in ruby and if my application gets big enough to warrant it get my own Postgresql I can host somewhere else. *note: since I was only able to post one link, cause I'm new, I decided to share a pastie with some relevant information
