• Excel - graphing mean and standard deviation

  - by joe_shmoe

  Hi all, I have measurements for multiple devices, and have their mean and sd values. I would like to produce a chart that would show these values, and I think the best would be if I could have something that looks like a bar chart(-ish) - the device names in x axis, values in y axis, and for each device to have a 'floating' bar that would represent values (mean - sd :: mean + sd), and some marker in the middle to show the actual mean value. is it doable? or would you suggest some other chart? Thanks a lot

• What are the standard directory layouts for source code?

  - by splattered bits

  I'm in the process of proposing a new standard directory layout that will be used across all the projects in our organization. Projects can have compiled source code, setup scripts, build scripts, third-party libraries, database scripts, resources, web services, web sites, etc. This is partly inspired by discovering Maven's standard layout. Are there any other standard layouts that are generally accepted in the industry?

• Setting a non-standard proxy

  - by Julio Guerra

  I am behind a proxy which requires users to login during the first connection with a username and password with a HTML form. Thus, it is not handled with usual http://username:[email protected] and any attempt to access the internet from this setting falls into the login form. How could I automatically login to the proxy? In linux, what manages proxy stuffs when a command tries to access the internet? Thank you.

• Cheap Solution for Routing a Toll Free Number to a Standard POTS Number

  - by VxJasonxV

  I do some technical work for an Internet Radio Show/Podcast, and need to fix something that has been broken for a while. The hosts have a Skype-In number to take listener calls, and for convenience sake, I bought and paid for a toll free number for a period of time. I used to use Asterlink for routing calls, but they folded and sent my number to OneBox, but they're ridiculously expensive by comparison. I'm looking for a cheap solution for this one simple task. Forward toll free calls to a skype-in number. The definition of cheap is as cheap or cheaper than Asterlink was. I paid something like $2 a month, and then the termination/call rate, which was a fraction of a sent for termination, and only whole cents after some serious time on the call. A $20 preload lasted me months at a time. I don't want to be upsold too, I want a simple web based management screen (CDR/stats are fun!), and obviously, it needs to be reliable. What vendors out there are you a fan of that solves this need?

• Windows Server 2003 Standard R2 CD 1 cannot boot: freeze at No Emulation

  - by TGP1994

  Hi everyone. I've been interested in the Windows Server line of OSes, so since I apply for DreamSpark, I thought I'd go download it and try it. I just so happened to have an old desktop that I was using awhile ago for Windows XP, so I imaged the drive in preparation for it to be overwritten with the new OS. (This system has an Asus A7V8X-X motherboard, an AMD Athlon XP 2800+ processor, and 1GB of RAM.) I tried burning the first disk image on my newer desktop computer, running Windows XP, although the CD burner consistently failed at a particular track area from cd to cd, so it seemed like the burner was toast there. Fortunately, I had a laptop, so I transferred the images over to that, then burned the first disc there. First time around went great, and the burning program reported no errors. I then took the CD over to the computer that I was intending to install Server onto, set the BIOS to boot from the CD drive, then I booted it up. Like normal, after the POST, it printed "Boot from ATAPI CD-Rom: No Emulation", which I was used to seeing with bootable cds. I waited for the "Press any key to continue..." message that I had become so familiar with in windows discs, although I saw none. The computer sat there for about 5 seconds with the cd spinning, then it spun down like it was done reading it. Nothing else happened. No response from the keyboard. I tried again, same result. I then downloaded IMGBurn, and I put the burned cd into the laptop that burned it originally. I also downloaded a fresh image from the dreamspark site. I ran a verify session, and everything checked out. I later tried getting various DOS startup discs, then I tried booting the winnt binary, which supposedly initiates the installation process. Either the shells reported that not enough memory was available (since they would be running in low memory mode), or FreeDOS in particular would report Illegal instructions right away. Is the image corrupt at dreamspark, or am I doing something wrong?

• (updated) Subfolder needs whitelist and standard redirect for all others

  - by Superstrong

  How can I allow access to the foo.html files in the .com/song/private/ subfolder for: a logged-in Wordpress user; or any referral domains (including subfolders) I add; or any URL on our own domain from the com/song/private folder; For all others, the user should be redirected to the corresponding public version of the Post, which is the same html filename and structured .com/song/foo.html. (The private versions uses a different template with different custom fields for each Post.) Update: Here's what I have so far: <Limit GET POST> order deny,allow deny from all allow from domain.com/song/private allow from otherdomain.com </Limit> RewriteRule ^(.*)$ ../$ [NC,L] More: Will that last rewrite rule take people back to the public version, from com/song/private/foo.html to com/song/foo.html? I found the following rule for detecting Wordpress logged-in status, but what do I put aferward with a RewriteRule, and will it work anyway? (If not, is there an alternative?) RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in_.*$ N.B. I have added code to my root .htaccess allowing me to insert additional .htaccess files in other subfolders as needed. Copied from Stack Overflow, where they suggested I ask here.

• Indicating end of Standard Input

  - by waiwai933

  How does one indicate that one has finished entering test in stdin? For example, let's say that I wish to encrypt 'blue' using MD5 (I know MD5 is unsecure, but just for this example). I tried user$ blue | md5 which I was led to understand is how one pipes input to stdin, but it doesn't work right. But if I just enter user$ md5 I can enter the word 'blue'. But how do I indicate to md5 that I'm finished entering text?

• Proper upgrade path for Windows 7 to Windows 8 when the directory setup is non-standard

  - by Joey

  I have both a HDD and a SSD in my computer and after installing Windows I moved things around a little to ensure that the OS is on the SSD but my user profile resides on the SSD (with a few exceptions). I used junction points heavily for that. Windows and most applications are fine with that and it works well. Now I wonder whether I can in-place upgrade this to Windows 8 while retaining that exact setup or whether there is anything I can do to ease the upgrade process.

• ESXI with non standard hardware HDD issues

  - by Hurricanepkt

  I have 3 very underutilized servers that I am condensing to one of those shuttle PC's with VMWare ESXi The HDD seems to be the bottle neck right now (the light is almost always pure solid) right now I have a single 1TB Seagate 7200.11 connected by SATA. VMWare ESXi cannot detect it when running in AHCI mode, but does when running in IDE mode. I have read that IDE mode can give a 5% performance hit which might give me enough breathing room. However, I am open to setting up an external eSATA or some sort of raid to give me more than just the 5%. I am just weary of sinking some money into a bit of hardware without knowledge of whether it will work. Does anyone know of resources or procedures of how to get this working.

• Stop Foxit PhantomPDF Standard from Opening PDFs in Internet Explorer 11

  - by pk.

  Is there a way to stop Foxit PhantomPDF from opening a linked PDF in the browser plugin? My desired behavior is for it to open the PDF in a Foxit PhantomPDF window. I've looked for an add-in, but there is none. Foxit support recommended the following solution -- select File Preferences File Associations Advanced Uncheck Include Browser... Select OK Select Make Default PDF Viewer but it didn't make a difference. How exactly is Internet Explorer making the decision to open it in the browser plugin instead of a separate PhantomPDF window? How can I change that?

• C headers: compiler specific vs library specific?

  - by leonbloy

  Is there some clear-cut distinction between standard C *.h header files that are provided by the C compiler, as oppossed to those which are provided by a standard C library? Is there some list, or some standard locations? Motivation: int this answer I got a while ago, regarding a missing unistd.h in the latest TinyC compiler, the author argued that unistd.h (contrarily to sys/unistd.h) should not be provided by the compiler but by your C library. I could not make much sense of that response (for one thing shouldn't that also apply to, say, stdio.h?) but I'm still wondering about it. Is that correct? Where is some authoritative reference for this? Looking in other compilers, I see that other "self contained" POSIX C compilers that are hosted in Windows (like the GCC toolchain that comes with MinGW, in several incarnations; or Digital Mars compiler), include all header files. And in a standard Linux distribution (say, Centos 5.10) I see that the gcc package provides a few header files (eg, stdbool.h, syslimits.h) in /usr/lib/gcc/i386-redhat-linux/4.1.1/include/, and the glibc-headers package provides the majority of the headers in /usr/include/ (including stdio.h, /usr/include/unistd.h and /usr/include/sys/unistd.h). So, in neither case I see support for the above claim.

• Standard Apache (not OHS) with mod_osso for Single Signon

  - by Markos Fragkakis

  The mod_osso.so (the Apache plugin for Single Signon, provided by Oracle) is distributed with the Oracle HTTP Server (OHS), which is essentially a modified Apache. I am trying to use it on the standard Apache HTTP Server, and have not managed to get it to work. Configuration: Apache 2.2.15 OHS from the Oracle Web Tier Tools 11.1.1.2.0 Red Hat Linux 64 bit I have: Included the module in the modules directory (copied from corresponding modules dir in OHS) Included the libraries libiau.so and libclutsh.so.11.1 from Oracle Home. The absence of these libraries produced an error on starting Apache. Produced a osso.conf using the ssoreg.sh tool provided with OID (the LDAP implementation of Oracle) Created the required mod_osso.conf file, which I included in httpd.conf. The error I get when starting Apache is this: # /opt/apache_sso/bin/apachectl -k start httpd: Syntax error on line 1075 of /opt/apache_sso/conf/httpd.conf: Syntax error on line 1 of /opt/apache_sso/conf/mod_osso.conf: Cannot load /opt/apache_sso/modules/mod_osso.so into server: /opt/apache_sso/modules/mod_osso.so: undefined symbol: _audit_authentication_request My mod_osso.conf: # cat /opt/apache_sso/conf/mod_osso.conf LoadModule osso_module modules/mod_osso.so <IfModule mod_osso.c> OssoIdleTimeout off OssoIpCheck on OssoConfigFile conf/osso.conf #Location is the URI you want to protect <Location /myapp> require valid-user #OHS 11g AuthType Osso #OHS 10g AuthType Basic AuthType Osso </Location> </IfModule> Has anyone made mod_osso work on standard Apache HTTP server?

• Using embedded standard HTML forms with ASP.NET

  - by RM

  I have a standard aspx page with which I need to add another standard HTML form into and have it submit to another location (external site), however whenever I press the submit button the page seems to do a post back rather than using the sub-forms action url. A mock up of what the form relationships is below. Note in the real deployment the form will be part of a content area of a master page layout, so the form needs to submit independantly from the master page form. <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <form id="subscribe_form" method="post" action="https://someothersite.com" name="em_subscribe_form" > <input type="text" id="field1" name="field1" /> <input id="submitsubform" type="submit" value="Submit" /> </form> </div> </form> </body> </html>

• reading dbase file without standard .dbf extension.

  - by Nathan W

  I am trying to read a file which is just a dbase file but without the standard extension the file is something like: Test.Dat I am using this block of code to try and read the file: string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Temp;Extended Properties=dBase III"; OleDbConnection dBaseConnection = new OleDbConnection(ConnectionString); dBaseConnection.Open(); OleDbDataAdapter oDataAdapter = new OleDbDataAdapter("SELECT * FROM Test", ConnectionString); DataSet oDataSet = new DataSet(); oDataAdapter.Fill(oDataSet);//I get the error right here... DataTable oDataTable = oDataSet.Tables[0]; foreach (DataRow dr in oDataTable.Rows) { Console.WriteLine(dr["Name"]); } Of course this crashes because it can't find the dbase file called test, but if I rename the file to Test.dbf it works fine. I can't really rename the file all the time because a third party application uses it as its file format. Does anyone know a way to read a dbase file without a standard extension in C#. Thanks.

• WPF DataBinding to standard CLR properties in code-behind

  - by nukefusion

  Hi everyone, Just learning WPF databinding and have a gap in my understanding. I've seen a few similar questions on StackOverflow, but I'm still struggling in determining what I have done wrong. I have a simple Person class with a Firstname and Surname property (standard CLR properties). I also have a standard CLR property on my Window class that exposes an instance of Person. I've then got some XAML, with two methods of binding. The first works, the second doesn't. Can anybody help me to understand why the second method fails? There's no binding error message in the Output log. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300" DataContext="{Binding RelativeSource={RelativeSource Self}, Path=MyPerson}"> <StackPanel> <Label>My Person</Label> <WrapPanel> <Label>First Name:</Label> <Label Content="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=MyPerson.FirstName}"></Label> </WrapPanel> <WrapPanel> <Label>Last Name:</Label> <Label Content="{Binding MyPerson.Surname}"></Label> </WrapPanel> </StackPanel> Edit: Ok, thanks so far. I've changed the second expression to: <Label Content="{Binding Surname}"></Label> I still can't get it to work though!

• What should the standard be for ReSTful URLS?

  - by gargantaun

  Since I can't find a chuffing job, I've been reading up on ReST and creating web services. The way I've interpreted it, the future is all about creating a web service for all your data before you build the web app. Which seems like a good idea. However, there seems to be a lot of contradictory thoughts on what the best scheme is for ReSTful URLs. Some people advocate simple pretty urls http://api.myapp.com/resource/1 In addition, some people like to add the API version to the url like so http://api.myapp.com/v1/resource/1 And to make things even more confusing, some people advocate adding the content-type to get requests http://api.myapp.com/v1/resource/1.xml http://api.myapp.com/v1/resource/1.json http://api.myapp.com/v1/resource/1.txt Whereas others think the content-type should be sent in the HTTP header. Soooooooo.... That's a lot of variation, which has left me unsure of what the best URL scheme is. I personally see the merits of the most comprehensive URL that includes a version number, resource locator and content-type, but I'm new to this so I could be wrong. On the other hand, you could argue that you should do "whatever works best for you". But that doesn't really fit with the ReST mentality as far as I can tell since the aim is to have a standard. And since a lot of you people will have more experience than me with ReST, I thought I'd ask for some guidance. So, with all that in mind... What should the standard be for ReSTful URLS?

• Career Choice in JEE, are EJBs standard?

  - by John Baker

  I have chosen to go the JEE route for a career path but I have been having a hard time determining which core technologies that I need to be most familiar with. I'm at the point I can write web apps without a problem with JSP's and regular servlets using JDBC or some basic Hibernate stuff (I know, HTML, CSS and have used MVC extensively on a number of different platforms). What I'm trying to find out is if there is some standard as far as J2EE technologies go. When I look at most of the Job listings, occasionally you will see someone mention Struts or Spring but rarely do I see any mention of EJB's. So my question is really, are EJB's basically required by most JEE employers? Or are most of them working with POJO's? Is it a mix? I have a hard time figuring out if I should put the majority of my time into Struts, Spring/Hibernate, EJB's, etc. And if I do need to master EJB's what version should I learn? 2.1 or 3.0. 3.0 has some obviously better features but I figure a lot of companies probably chose to write their apps in 2.1 just because it was the standard of the time and now migrating would be a big deal. Any advice on this is greatly appreciated.

• Python Error-Checking Standard Practice

  - by chaindriver

  Hi, I have a question regarding error checking in Python. Let's say I have a function that takes a file path as an input: def myFunction(filepath): infile = open(filepath) #etc etc... One possible precondition would be that the file should exist. There are a few possible ways to check for this precondition, and I'm just wondering what's the best way to do it. i) Check with an if-statement: if not os.path.exists(filepath): raise IOException('File does not exist: %s' % filepath) This is the way that I would usually do it, though the same IOException would be raised by Python if the file does not exist, even if I don't raise it. ii) Use assert to check for the precondition: assert os.path.exists(filepath), 'File does not exist: %s' % filepath Using asserts seems to be the "standard" way of checking for pre/postconditions, so I am tempted to use these. However, it is possible that these asserts are turned off when the -o flag is used during execution, which means that this check might potentially be turned off and that seems risky. iii) Don't handle the precondition at all This is because if filepath does not exist, there will be an exception generated anyway and the exception message is detailed enough for user to know that the file does not exist I'm just wondering which of the above is the standard practice that I should use for my codes.

• Is there a general-purpose printf-ish routine defined in any C standard

  - by supercat

  In many C libraries, there is a printf-style routine which is something like the following: int __vgprintf(void *info, (void)(*print_function(void*, char)), const char *format, va_list params); which will format the supplied string and call print_function with the passed-in info value and each character in sequence. A function like fprintf will pass __vgprintf the passed-in file parameter and a pointer to a function which will cast its void* to a FILE* and output the passed-in character to that file. A function like snprintf will create a struct holding a char* and length, and pass the address of that struct to a function which will output each character in sequence, space permitting. Is there any standard for such a function, which could be used if e.g. one wanted a function to output an arbitrary format to a TCP port? A common approach is to allocate a buffer one hopes is big enough, use snprintf to put the data there, and then output the data from the buffer. It would seem cleaner, though, if there were a standard way to to specify that the print formatter should call a user-supplied routine with each character.
