Jiri Kremser Date 05.11.2017 Number of pages 70+4 Language English Abstract Rise of microservices and distributed applications in containerized deployments are putting increasing amount of burden to the monitoring systems. They push the storage requirements to provide suitable performance for large queries. In this paper we present the changes we made to our distributed time series database, Hawkular-Metrics, and how it stores data more effectively in the Cassandra. We show that using our methods provides significant space savings ranging from 50 to 95% reduction in storage usage, while reducing the query times by over 90% compared to the nominal approach when using Cassandra. We also provide our unique algorithm modified from Gorilla compression algorithm that we use in our solution, which provides almost three times the throughput in compression with equal compression ratio.

When it comes to digital steganography no stone should be left unturned in the search for viable hidden data. Although digital steganography is commonly used to hide data inside multimedia files, a similar approach can be used to hide data in archives as well. Steganography imposes the following data hiding rule: Data must be hidden in such a fashion that the user has no clue about the hidden message or file's existence. This can be achieved by

  • Chapter 11. Media Formats for Data Submission and Archive 11-1
    Chapter 11. Media Formats for Data Submission and Archive 11-1 Chapter 11. Media Formats for Data Submission and Archive This standard identifies the physical media formats to be used for data submission or delivery to the PDS or its science nodes. The PDS expects flight projects to deliver all archive products on magnetic or optical media. Electronic delivery of modest volumes of special science data products may be negotiated with the science nodes. Archive Planning - During archive planning, the data producer and PDS will determine the medium (or media) to use for data submission and archiving. This standard lists the media that are most commonly used for submitting data to and subsequently archiving data with the PDS. Delivery of data on media other than those listed here may be negotiated with the PDS on a case- by-case basis. Physical Media for Archive - For archival products only media that conform to the appropriate International Standards Organization (ISO) standard for physical and logical recording formats may be used. 1. The preferred data delivery medium is the Compact Disk (CD-ROM or CD-Recordable) produced in ISO 9660 format, using Interchange Level 1, subject to the restrictions listed in Section 10.1.1. 2. Compact Disks may be produced in ISO 9660 format using Interchange Level 2, subject to the restrictions listed in Section 10.1.2. 3. Digital Versatile Disk (DVD-ROM or DVD-R) should be produced in UDF-Bridge format (Universal Disc Format) with ISO 9660 Level 1 or Level 2 compatibility. Because of hardware compatibility and long-term stability issues, the use of 12-inch Write Once Read Many (WORM) disk, 8-mm Exabyte tape, 4-mm DAT tape, Bernoulli Disks, Zip disks, Syquest disks and Jaz disks is not recommended for archival use.

  • Real Time Operating Systems Rootfs Creation: Summing Up
    Real Time Operating Systems RootFS Creation: Summing Up Luca Abeni Real Time Operating Systems – p. System Boot System boot → the CPU starts executing from a well-known address ROM address: BIOS → read the first sector on the boot device, and executes it Bootloader (GRUB, LILO, U-Boot, . .) In general, load a kernel and an “intial ram disk” The initial fs image isn’t always needed (example: netboot) Kernel: from arm-test-*.tar.gz Initial filesystem? Loaded in RAM without the kernel help Generally contains the boot scripts and binaries Real Time Operating Systems – p. Initial Filesystem Old (2.4) kernels: Init Ram Disk (initrd); New (2.6) kernels: Init Ram Filesystem (initramfs) Generally used for modularized disk and FS drivers Example: if IDE drivers and Ext2 FS are modules (not inside the kernel), how can the kernel load them from disk? Solution: boot drivers can be on initrd / initramfs The bootloader loads it from disk with the kernel The kernel creates a “fake” fs based on it Modules are loaded from it Embedded systems can use initial FS for all the binaries Qemu does not need a bootloader to load kernel and initial FS (-kernel and -initrd) Real Time Operating Systems – p. Init Ram Filesystem Used in 2.6 kernels It is only a RAM FS: no real filesystem metadata on a storage medium All the files that must populate the FS are stored in a cpio package (similar to tar or zip file) The bootloader loads the cpio file in ram At boot time, the kernel “uncompresses” it, creating the RAM FS, and populating it with the files contained in the archive The cpio archive can be created by using the cpio -o -H newc command (see man cpio) Full command line: find .

The Ark Handbook Chapter 1 Introduction Ark is a program for viewing, extracting, creating and modifying archives. Ark can handle vari- ous archive formats such as tar, gzip, bzip2, zip, rar, 7zip, xz, rpm, cab, deb, xar and AppImage (support for certain archive formats depends on the appropriate command-line programs being installed). In order to successfully use Ark, you need KDE Frameworks 5. The library libarchive version 3.1 or above is needed to handle most archive types, including tar, compressed tar, rpm, deb and cab archives. To handle other file formats, you need the appropriate command line programs, such as zipinfo, zip, unzip, rar, unrar, 7z, lsar, unar and lrzip. 5 The Ark Handbook Chapter 2 Using Ark 2.1 Opening Archives To open an archive in Ark, choose Open... (Ctrl+O) from the Archive menu. You can also open archive files by dragging and dropping from Dolphin.

If this page seems suspiciously similar to the PNG Home Page , rest assured that the similarity is completely coincidental. No, really. zlib was written by Jean-loup Gailly (compression) and Mark Adler (decompression). Current release: zlib 1.2.6 January 29, 2012 Version 1.2.6 has many changes over 1.2.5, including these improvements: gzread() can now read a file that is being written concurrently gzgetc() is now a macro for increased speed Added a 'T' option to gzopen() for transparent writing (no compression) Added deflatePending() to return the amount of pending output Allow deflateSetDictionary() and inflateSetDictionary() at any time in raw mode deflatePrime() can now insert bits in the middle of the stream ./configure now creates a configure.log file with all of the results Added a ./configure --solo option to compile zlib with no dependency on any libraries Fixed a problem with large file support macros Fixed a bug in contrib/puff Many portability improvements You can also look at the complete Change Log . Version 1.2.5 fixes bugs in gzseek() and gzeof() that were present in version 1.2.4 (March 2010). All users are encouraged to upgrade immediately. Version 1.2.4 has many changes over 1.2.3, including these improvements:
