  • PASS: 2013 Summit Location

    - by Bill Graziano
    HQ recently posted a brief update on our search for a location for 2013.  It includes links to posts by four Board members and two community members. I’d like to add my thoughts to the mix and ask you a question.  But I can’t give you a real understanding without telling you some history first. So far we’ve had the Summit in Chicago, San Francisco, Orlando, Dallas, Denver and Seattle.  Each has a little different feel and distinct memories.  I enjoyed getting drinks by the pool in Orlando after the sessions ended.  I didn’t like that our location in Dallas was so far away from all the nightlife.  Denver was in downtown but we had real challenges with hotels.  I enjoyed the different locations.  I always enjoyed the announcement during the third keynote with the location of the next Summit. There are two big events that impacted my thinking on the Summit location.  The first was our transition to the new management company in early 2007.  The event that September in Denver was put on with a six month planning cycle by a brand new headquarters staff.  It wasn’t perfect but came off much better than I had dared to hope.  It also moved us out of the cookie cutter conferences that we used to do into a model where we have a lot more control.  I think you’ll all agree that the production values of our last few Summits have been fantastic.  That Summit also led to our changing relationship with Microsoft.  Microsoft holds two seats on the PASS Board.  All the PASS Board members face the same challenge: we all have full-time jobs and PASS comes in second place professionally (or sometimes further back).  Starting in 2008 we were assigned a liaison from Microsoft that had a much larger block of time to coordinate with us.  That changed everything between PASS and Microsoft.  Suddenly we were talking to product marketing, Microsoft PR, their event team, the Tech*Ed team, the education division, their user group team and their field sales team – locally and internationally.  We strengthened our relationship with CSS, SQLCAT and the engineering teams.  We had exposure at the executive level that we’d never had before.  And their level of participation at the Summit changed from under 100 people to 400-500 people.  I think those 400+ Microsoft employees have value at a conference on Microsoft SQL Server.  For the first time, Seattle had a real competitive advantage over other cities. I’m one that looked very hard at staying in Seattle for a long, long time.  I think those Microsoft engineers have value to our attendees.  I think the increased support that Microsoft can provide when we’re in Seattle has value to our attendees.  But that doesn’t tell the whole story.  There’s a significant (and vocal!) percentage of our membership that wants the Summit outside Seattle.  Post-2007 PASS doesn’t know what it’s like to have a Summit outside of Seattle.  I think until we have a Summit in another city we won’t really know the trade-offs. I think a model where we move every third or every other year is interesting.  But until we have another Summit outside Seattle and we can evaluate the logistics and how important it is to have depth and variety in our Microsoft participation we won’t really know. Another benefit that comes with a move is variety or diversity.  I learn more when I’m exposed to new things and new people.  I believe that moving the Summit will give a different set of people an opportunity to attend. Grant Fritchey writes “It seems that the board is leaning, extremely heavily, towards making it a permanent fixture in Seattle.”  I don’t believe that’s true.  I know there was discussion of that earlier but I don’t believe it’s true now. And that brings me to my question.  Do we announce the city now or do we wait until the 2012 Summit?  I’m happy to announce Seattle vs. not-Seattle as soon as we sign the contract.  But I’d like to leave the actual city announcement until the 2011 Summit.  I like the drama and mystery of it.  I also like that it doesn’t give you a reason to skip a Summit and wait for the next one if it’s closer or back in Seattle.  The other side of the coin is that your planning is easier if you know where it is.  What do you think?

  • elffile: ELF Specific File Identification Utility

    - by user9154181
    Solaris 11 has a new standard user level command, /usr/bin/elffile. elffile is a variant of the file utility that is focused exclusively on linker related files: ELF objects, archives, and runtime linker configuration files. All other files are simply identified as "non-ELF". The primary advantage of elffile over the existing file utility is in the area of archives — elffile examines the archive members and can produce a summary of the contents, or per-member details. The impetus to add elffile to Solaris came from the effort to extend the format of Solaris archives so that they could grow beyond their previous 32-bit file limits. That work introduced a new archive symbol table format. Now that there was more than one possible format, I thought it would be useful if the file utility could identify which format a given archive is using, leading me to extend the file utility: % cc -c ~/hello.c % ar r foo.a hello.o % file foo.a foo.a: current ar archive, 32-bit symbol table % ar r -S foo.a hello.o % file foo.a foo.a: current ar archive, 64-bit symbol table In turn, this caused me to think about all the things that I would like the file utility to be able to tell me about an archive. In particular, I'd like to be able to know what's inside without having to unpack it. The end result of that train of thought was elffile. Much of the discussion in this article is adapted from the PSARC case I filed for elffile in December 2010: PSARC 2010/432 elffile Why file Is No Good For Archives And Yet Should Not Be Fixed The standard /usr/bin/file utility is not very useful when applied to archives. When identifying an archive, a user typically wants to know 2 things: Is this an archive? Presupposing that the archive contains objects, which is by far the most common use for archives, what platform are the objects for? Are they for sparc or x86? 32 or 64-bit? Some confusing combination from varying platforms? The file utility provides a quick answer to question (1), as it identifies all archives as "current ar archive". It does nothing to answer the more interesting question (2). To answer that question, requires a multi-step process: Extract all archive members Use the file utility on the extracted files, examine the output for each file in turn, and compare the results to generate a suitable summary description. Remove the extracted files It should be easier and more efficient to answer such an obvious question. It would be reasonable to extend the file utility to examine archive contents in place and produce a description. However, there are several reasons why I decided not to do so: The correct design for this feature within the file utility would have file examine each archive member in turn, applying its full abilities to each member. This would be elegant, but also represents a rather dramatic redesign and re-implementation of file. Archives nearly always contain nothing but ELF objects for a single platform, so such generality in the file utility would be of little practical benefit. It is best to avoid adding new options to standard utilities for which other implementations of interest exist. In the case of the file utility, one concern is that we might add an option which later appears in the GNU version of file with a different and incompatible meaning. Indeed, there have been discussions about replacing the Solaris file with the GNU version in the past. This may or may not be desirable, and may or may not ever happen. Either way, I don't want to preclude it. Examining archive members is an O(n) operation, and can be relatively slow with large archives. The file utility is supposed to be a very fast operation. I decided that extending file in this way is overkill, and that an investment in the file utility for better archive support would not be worth the cost. A solution that is more narrowly focused on ELF and other linker related files is really all that we need. The necessary code for doing this already exists within libelf. All that is missing is a small user-level wrapper to make that functionality available at the command line. In that vein, I considered adding an option for this to the elfdump utility. I examined elfdump carefully, and even wrote a prototype implementation. The added code is small and simple, but the conceptual fit with the rest of elfdump is poor. The result complicates elfdump syntax and documentation, definite signs that this functionality does not belong there. And so, I added this functionality as a new user level command. The elffile Command The syntax for this new command is elffile [-s basic | detail | summary] filename... Please see the elffile(1) manpage for additional details. To demonstrate how output from elffile looks, I will use the following files: FileDescription configA runtime linker configuration file produced with crle dwarf.oAn ELF object /etc/passwdA text file mixed.aArchive containing a mixture of ELF and non-ELF members mixed_elf.aArchive containing ELF objects for different machines not_elf.aArchive containing no ELF objects same_elf.aArchive containing a collection of ELF objects for the same machine. This is the most common type of archive. The file utility identifies these files as follows: % file config dwarf.o /etc/passwd mixed.a mixed_elf.a not_elf.a same_elf.a config: Runtime Linking Configuration 64-bit MSB SPARCV9 dwarf.o: ELF 64-bit LSB relocatable AMD64 Version 1 /etc/passwd: ascii text mixed.a: current ar archive, 32-bit symbol table mixed_elf.a: current ar archive, 32-bit symbol table not_elf.a: current ar archive same_elf.a: current ar archive, 32-bit symbol table By default, elffile uses its "summary" output style. This output differs from the output from the file utility in 2 significant ways: Files that are not an ELF object, archive, or runtime linker configuration file are identified as "non-ELF", whereas the file utility attempts further identification for such files. When applied to an archive, the elffile output includes a description of the archive's contents, without requiring member extraction or other additional steps. Applying elffile to the above files: % elffile config dwarf.o /etc/passwd mixed.a mixed_elf.a not_elf.a same_elf.a config: Runtime Linking Configuration 64-bit MSB SPARCV9 dwarf.o: ELF 64-bit LSB relocatable AMD64 Version 1 /etc/passwd: non-ELF mixed.a: current ar archive, 32-bit symbol table, mixed ELF and non-ELF content mixed_elf.a: current ar archive, 32-bit symbol table, mixed ELF content not_elf.a: current ar archive, non-ELF content same_elf.a: current ar archive, 32-bit symbol table, ELF 64-bit LSB relocatable AMD64 Version 1 The output for same_elf.a is of particular interest: The vast majority of archives contain only ELF objects for a single platform, and in this case, the default output from elffile answers both of the questions about archives posed at the beginning of this discussion, in a single efficient step. This makes elffile considerably more useful than file, within the realm of linker-related files. elffile can produce output in two other styles, "basic", and "detail". The basic style produces output that is the same as that from 'file', for linker-related files. The detail style produces per-member identification of archive contents. This can be useful when the archive contents are not homogeneous ELF object, and more information is desired than the summary output provides: % elffile -s detail mixed.a mixed.a: current ar archive, 32-bit symbol table mixed.a(dwarf.o): ELF 32-bit LSB relocatable 80386 Version 1 mixed.a(main.c): non-ELF content mixed.a(main.o): ELF 64-bit LSB relocatable AMD64 Version 1 [SSE]

  • apt-get doesnt download files from NFS location

    - by Pravesh
    I have switched to unix from last 3 months and trying to understand install process and in particular apt-get. I am able to successfully install and download the packages when I configure my repository on http location in /etc/apt/sources.list file. e.g. deb http://web.myspqce.com/u/eng/rose/debian-mirror-squeeze-amd64/mirror/ftp.us.debian.org/debian/ squeeze main contrib non-free This command will download(/var/cache/apt/archive) and install the package when i use apt-get install When I change the source location to file instead of http(nfs mount point), the package is getting installed but NOT getting downloaded in /var/cache/apt/archive. deb file:/deb_repository/debian-mirror-squeeze-amd64/mirror/ftp.us.debian.org/debian/ squeeze main contrib non-free Please let me know if there is any configuration or settings that i have to make to let apt-get to both download and install package when i use (nfs)file:/ instead of http:/ in sources.list. To achieve this, I can use apt-get --downlaod-only and then use apt-get install for both download and install in two separate calls, but I want to know why package is not getting downloaded with apt-get install but only getting installed when used with file:/ in sources.list

  • VB.NET 2008, Windows 7 and saving files

    - by James Brauman
    Hello, We have to learn VB.NET for the semester, my experience lies mainly with C# - not that this should make a difference to this particular problem. I've used just about the most simple way to save a file using the .NET framework, but Windows 7 won't let me save the file anywhere (or anywhere that I have found yet). Here is the code I am using to save a text file. Dim dialog As FolderBrowserDialog = New FolderBrowserDialog() Dim saveLocation As String = dialog.SelectedPath ... Build up output string ... Try ' Try to write the file. My.Computer.FileSystem.WriteAllText(saveLocation, output, False) Catch PermissionEx As UnauthorizedAccessException ' We do not have permissions to save in this folder. MessageBox.Show("Do not have permissions to save file to the folder specified. Please try saving somewhere different.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error) Catch Ex As Exception ' Catch any exceptions that occured when trying to write the file. MessageBox.Show("Writing the file was not successful.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error) End Try The problem is that this using this code throws an UnauthorizedAccessException no matter where I try to save the file. I've tried running the .exe file as administrator, and the IDE as administrator. Is this just Windows 7 being overprotective? And if so, what can I do to solve this problem? The requirements state that I be able to save a file! Thanks.

  • compressed archive with quick access to individual file

    - by eric.frederich
    I need to come up with a file format for new application I am writing. This file will need to hold a bunch other text files which are mostly text but can be other formats as well. Naturally, a compressed tar file seems to fit the bill. The problem is that I want to be able to retrieve some data from the file very quickly and getting just a particular file from a tar.gz file seems to take longer than it should. I am assumeing that this is because it has to decompress the entire file even though I just want one. When I have just a regular uncompressed tar file I can get that data real quick. Lets say the file I need quickly is called data.dat For example the command... tar -x data.dat -zf myfile.tar.gz ... is what takes a lot longer than I'd like. MP3 files have id3 data and jpeg files have exif data that can be read in quickly without opening the entire file. I would like my data.dat file to be available in a similar way. I was thinking that I could leave it uncompressed and seperate from the rest of the files in myfile.tar.gz I could then create a tar file of data.dat and myfile.tar.gz and then hopefully that data would be able to be retrieved faster because it is at the head of outer tar file and is uncompressed. Does this sound right?... putting a compressed tar inside of a tar file? Basically, my need is to have an archive type of file with quick access to one particular file. Tar does this just fine, but I'd also like to have that data compressed and as soon as I do that, I no longer have quick access. Are there other archive formats that will give me that quick access I need? As a side note, this application will be written in Python. If the solution calls for a re-invention of the wheel with my own binary format I am familiar with C and would have no problem writing the Python module in C. Idealy I'd just use tar, dd, cat, gzip, etc though. Thanks, ~Eric

  • Read from file in eclipse

    - by Buzkie
    I'm trying to read from a text file to input data to my java program. However, eclipse continuosly gives me a Source not found error no matter where I put the file. I've made an additional sources folder in the project directory, the file in question is in both it and the bin file for the project and it still can't find it. I even put a copy of it on my desktop and tried pointing eclipse there when it asked me to browse for the source lookup path. No matter what I do it can't find the file. here's my code in case it's pertinent: System.out.println(System.getProperty("user.dir")); File file = new File("file.txt"); Scanner scanner = new Scanner(file); in addition, it says the user directory is the project directory and there is a copy there too. I have no clue what to do. Thanks, Alex after attempting the suggestion below and refreshing again, I was greeted by a host of errors.

  • Why I have to call 'exit' after redirection through header('Location..') in PHP?

    - by Nicolò Martini
    You know that if you want to redirect an user in PHP you can use the header function: header('Location: http://smowhere.com'); It is also well known that it is a good practice to put also an exit; after the header call, to prevent execution of other php code. So my question is: could the code after the header-location call be effectively executed? In which cases? Can a malicious user be able to completely ignore the header('Location..') call? How?

  • how do you find a file's location?

    - by home-directory
    Noob here. OK, I 1 Open the Dash. 2 Type "file". An app appears, called "files", icon looks like ta 2-drawer file cabinet. I click that, the app opens 3: I click the "Search button". I type the file name in the box and hit Enter. 4: The program thinks for a while, then displays a result. Great! the program found the file I was ilooking for! IT knows where myfile.foo is, BUT I DON'T! IT DOESN'T F%*%#ING SAY WHERE IT IS!!!! How do I find out where it is, please? I hate to say this, but is there an app that works like Windows Explorer (but doesn't crash every 2 minutes)?

  • C: reading file and populating struct

    - by deostroll
    Hi, I have a structure with the following definition: typedef struct myStruct{ int a; char* c; int f; } OBJECT; I am able to populate this object and write it to a file. However I am not able to read the char* c value in it...while trying to read it, it gives me a segmentation fault error. Is there anything wrong with my code: //writensave.c #include "mystruct.h" #include <stdio.h> #include <string.h> #define p(x) printf(x) int main() { p("Creating file to write...\n"); FILE* file = fopen("struct.dat", "w"); if(file == NULL) { printf("Error opening file\n"); return -1; } p("creating structure\n"); OBJECT* myObj = (OBJECT*)malloc(sizeof(OBJECT)); myObj->a = 20; myObj->f = 45; myObj->c = (char*)calloc(30, sizeof(char)); strcpy(myObj->c, "This is a test"); p("Writing object to file...\n"); fwrite(myObj, sizeof(OBJECT), 1, file); p("Close file\n"); fclose(file); p("End of program\n"); return 0; } Here is how I am trying to read it: //readnprint.c #include "mystruct.h" #include <stdio.h> #define p(x) printf(x) int main() { FILE* file = fopen("struct.dat", "r"); char* buffer; buffer = (char*) malloc(sizeof(OBJECT)); if(file == NULL) { p("Error opening file"); return -1; } fread((void *)buffer, sizeof(OBJECT), 1, file); OBJECT* obj = (OBJECT*)buffer; printf("obj->a = %d\nobj->f = %d \nobj->c = %s", obj->a, obj->f, obj->c); fclose(file); return 0; }

  • Get location of "true" GVFS path from Nautilus

    - by user946850
    I mount my Samba shares through Nautilus. I know that, behind the scenes, the share is fuse-mounted and Nautilus somehow does the translation between smb:// URLs and the actual location in the file system. Is it possible to retrieve the "true" path in the file system for a GVFS-mounted share, for a directory or a file? How? This is related, but does not answer my question: How to copy the current path from Nautilus?

  • How to securely enable file sharing over PPTP on Windows 2008 Server

    - by Damage
    I have set up a Windows SBS 2003 domain (LAN) and a stand-alone Windows 2008 Server (web server) at another location (workgroup). I established PPTP VPN connection (SBS dials web server) over which users from LAN should be able to access web server. On web server I enabled TCP/IPv4 and File and Printer sharing protocol. It has a few external addresses (one of them is default) AND one local address (192.x.x.x) assigned to network adapter. Firewall allows port 445 for file sharing. There's the problem - I can not enable web server file shares to be visible to LAN users and ONLY to LAN users: From SBS I can access webserver but I cannot access webserver from LAN workstations (XP, Vista). I have had same configuration - I have just replaced old (web server) Windows 2003 server with 2008 so SBS settings are the same (static route, DNS etc.). How can I enable file sharing on web server for LAN workstations? Now I have opened File and printer sharing to the internet which is of course totaly unsecure. I tried to secure the tunnel so I moved RAS (VPN) connection (Network Center) on web server to "Private" profile and moved firewall port 445 to "Private" profile but suddenly file sharing does not work and I cannot telnet webserver on port 445. How can I secure file sharing so I do not have to open it to the internet?

  • Advanced Linux file permission question (ownership change during write operation)

    - by Kent
    By default the umask is 0022: usera@cmp$ touch somefile; ls -l total 0 -rw-r--r-- 1 usera usera 0 2009-09-22 22:30 somefile The directory /home/shared/ is meant for shared files and should be owned by root and the shared group. Files created here by usern (any user) are automatically owned by the shared group. There is a cron-job taking care of changing owning user and owning group (of any moved files) once per day: usera@cmp$ cat /etc/cron.daily/sharedscript #!/bin/bash chown -R root:shared /home/shared/ chmod -R 770 /home/shared/ I was writing a really large file to the shared directory. It had me (usera) as owning user and the shared group as group owner. During the write operation the cron job was run, and I still had no problem completing the write process. You see. I thought this would happen: I am writing the file. The file permissions and ownership data for the file looks like this: -rw-r--r-- usera shared The cron job kicks in! The chown line is processed and now the file is owned by the root user and the shared group. As the owning group only has read access to the file I get a file write error! Boom! End of story. Why did the operation succeed? A link to some kind of reference documentation to back up the reason would be very welcome (as I could use it to study more details).

  • Dual pane file manager for Mac OS X

    - by Alex Kaushovik
    Is there a good customizable dual-pane file manager for Mac like Total Commander / Far Manager in Windows, or like Krusader / Midnight Commander in Linux? I used to work on Windows for quite a while and mostly used Far Manager and sometimes Total Commander, then I switched to Ubuntu Linux and used Krusader, now I switched to Mac OS (Snow Leopard) and I'm having a hard time trying to find a good file manager... Many of the existing applications are trying to replace the Finder with "multimedia capabilities nobody cares about in file manager - IMHO" (Path Finder, ForkLift), some of them are almost good dual-pane file managers (couldn't remember examples), but none of them worked for me mostly because of one reason: I couldn't integrate my file/folder comparison utility (Araxis Merge for Mac) with them... The way it worked for me in Windows and Linux is that I was setting the cursor on one file in the left pane, then setting the right-pane cursor on another file in right pane, then I pressed a hotkey that launched Araxis Merge with those to files/folders comparison results. It was very easy to set up in Far Manager (Windows) and Krusader (Linux, actually in Linux I used "Meld" instead of Araxis Merge...) The tool I'm looking for doesn't necessarily has to be free... Thank you!

  • Office Compatibility Pack and File Permissions

    - by hymie
    MS isn't my thing, so I hope somebody can give me a pointer. We have a Windows domain, with a Server-2003-SP1-Enterprise file server. One of the specific files is a MS Excel 2007 (XLSX) file created by user LK. In the "Security" preferences setting, about a half-dozen users (including me) have access to this file. LK is the owner and has "full control", while the rest of us have "Read" , "Read & Execute", and "Write" permission. LK is also the owner of the directory that this file resides in. I don't know if that's relevant. So far so good. My desktop machine has Windows XP SP3 , and Excel 2003 SP3 , and the "Office Compatibility Pack" which lets me read and write the new XLSX files. However, whenever I write the file, the permissions are changed. The newly-written file only has permissions for LK and me, and both are "Full control" So in short, what am I doing wrong, and how should I set this up to do it right, keeping the permissions on the file that were there when I started?

  • One row is skipped each time the program scans a matrix from file !

    - by ZaZu
    Hello there, I had this code working yesterday, but it seems like I edited it a bit and lost the working version. I cant get this to work anymore. I basically want to scan a matrix from a .txt file. But each time it scans the first row, the second one is skipped, and it reads the third instead :( Here is my code : for(i=0;i<=test->rowmat1;i++){ for(j=0;j<=test->colmat1;j++){ fscanf(fin,"%f\t",&test->mat[i][j]); } fscanf(fin,"%*[^\n]",&test->mat[i][j]); } For example, for a matrix of : 1.00 2.00 3.00 4.00 5.00 6.00 7.00 8.00 9.00 10.00 11.00 12.00 If I extract 3 rows and 3 cols, I get : 1.00 2.00 3.00 7.00 8.00 9.00 Then fails, it wants to skip over the second line but there is nothing after 10 11 12 Why did it stop working ? What do I have wrong ? Please help, Thanks in advance.

  • Drawbacks with reading and writing a big file to or from disk at once instead of small chunks?

    - by Johann Gerell
    I work mainly on Windows and Windows CE based systems, where CreateFile, ReadFile and WriteFile are the work horses, no matter if I'm in native Win32 land or in managed .Net land. I have so far never had any obvious problem writing or reading big files in one chunk, as opposed to looping until several smaller chunks are processed. I usually delegate the IO work to a background thread that notifies me when it's done. But looking at file IO tutorials or "textbook examples", I often find the "loop with small chunks" used without any explanation of why it's used instead of the more obvious (I dare to say!) "do it all at once". Are there any drawbacks to the way I do that I haven't understood?

  • Fatal error when using FILE* in Windows from DLL

    - by AlannY
    Hi there. Recently, I found a problem with Visual C++ 2008 compiler, but using minor hack avoid it. Currently, I cannot use the same hack, but problem exists as in 2008 as in 2010 (Express). So, I've prepared for you 2 simple C file: one for DLL, one for program: DLL (file-dll.c): #include <stdio.h> __declspec(dllexport) void print_to_stream (FILE *stream) { fprintf (stream, "OK!\n"); } And for program, which links this DLL via file-dll.lib: Program: #include <stdio.h> __declspec(dllimport) void print_to_stream (FILE *stream); int main (void) { print_to_stream (stdout); return 0; } To compile and link DLL: cl /LD file-dll.c To compile and link program: cl file-test.c file-dll.lib When invoking file-test.exe, I got the fatal error (similar to segmentation fault in UNIX). As I said early, I had that the same problem before: about transferring FILE* pointer to DLL. I thought, that it may be because of compiler mismatch, but now I'm using one compiler for everything and it's not the problem. ;-( What can I do now? UPD: I've found solution: cl /LD /MD file-dll.c cl /MD file-test.c file-dll.lib The key is to link to dynamic library, but (I did not know it) by default it links staticaly and (hencefore) error occurs (I see why). P.S. Thanks for patience.
