  • Can someone provide an example of seeking, reading, and writing a >4GB file using boost iostreams

    - by Queueless
    I have read that boost iostreams supposedly supports 64 bit access to large files semi-portable way. Their FAQ mentions 64 bit offset functions, but there is no examples on how to use them. Has anyone used this library for handling large files? A simple example of opening two files, seeking to their middles, and copying one to the other would be very helpful. Thanks.

  • Scrubbing IPv4 dotted-quad addresses in SQL

    - by pilcrow
    Given a table containing dotted quad IPv4 addresses stored as a VARCHAR(15), for example: ipv4 -------------- 172.16.1.100 172.16.50.5 172.30.29.28 what's a convenient way to SELECT all "ipv4" fields with the final two octets scrubbed, so that the above would become: ipv4 ------------ 172.16.x.y 172.16.x.y 172.30.x.y Target RDBMS is postgresql 8.4, but the more portable the better! Thanks.

  • Merge LVM Partition with unallocated Space

    - by David
    I have a linux hard drive with three areas: /dev/hda1 - ext3 boot partition (20 MB) /dev/hda2 - lvm2 main partition (6 GB) unpartitioned space - 12 GB I would like to merge the unpartitioned space into the lvm2 partition known as /dev/hda2. I tried using GParted, but it does not support lvm2. What commands or utilities could I use to add the unpartitioned space to hda2 without losing my existing data?

  • Good Package for Fitting Polynomial Trend Lines

    - by Rev316
    Given a simple data set, I would like to be able to calculate a trending formula given it's a second order polynomial regression. In fact, it would be great if one could even forecast X periods during calculation (similar to what Excel does). I'm looking for a portable C/C++ package that's relatively easy to use, and allows it to spit out the "best-fit" (highest R^2 value) curve. Any suggestions? Thanks!

  • WinAPI magic and MONO runtime

    - by Luca
    I'm trying to get the same result of a .NET application (see the link Hide TabControl buttons to manage stacked Panel controls for details), but using the MONO runtime instead of the MS .NET runtime. Pratically, when the custom control is executed using the MONO runtime, the underlying message is not sent to the control, causing the tab pages to be shown... Is there a portable solution which is elegant as the linked one? If it is not possible, what are possible workarounds (apart from removing/adding tabs at runtime)?

  • Portability of pthreads-win32 over various compilers.

    - by Artyom
    Hello, I'm using pthreads-win32 for portable threading support for windows. At least, according to the documentation pthreads-win32 should work with MSVC and even MSVC builds provided. But I don't know if the library is tested with latest MSVC compilers like MSVC-2008 and if it is supported under 64bit windows. Does anybody aware of any issues with this library? Note: Do not even try to recommend using Boost.Thread, I'm not interested in. And I'm familiar with Boost.Thread library

  • Good Wireless Range Extender

    - by Joseph Sturtevant
    Can anyone recommend a good wireless (802.11g) range extender? I would like to find something that will provide reliable wireless to areas of the building that aren't covered or get poor reception. I would also like a product that won't require big changes to my current wireless setup (multiple APs with a wireless controller are out). Latency and bandwidth aren't terribly important. Does anyone have experience with a product like this?

  • Autodetect console output encoding in perl

    - by n0rd
    I have a perl script that prints some information to console in Russian. Script will be executed on several OSes, so console encoding can be cp866, koi8-r, utf-8, or some other.

  • Alternatives to fread and fwrite for use with structured data

    - by forest58
    The book Beginning Linux Programming (3rd ed) says "Note that fread and fwrite are not recommended for use with structured data. Part of the problem is that files written with fwrite are potentially nonportable between different machines." What does that mean exactly? What calls should I use if I want to write a portable structured data reader or writer? Direct system calls?

  • Installing Python in Windows XP

    - by Sam
    My work PC has restrictions that stop me from adding programs to the start menu so when I try to install Python using the Python 2.6.5 Windows installer it can't complete as it tries to add a shortcut to my start menu. Is there a way around this? I.e another way of installing without the need for a shortcut? Edit: I'll also need to install NumPy which I can't do on the Portable version of Python.
