  • How can I deactivate the gnome desktop of my ubuntu server?

    - by 19 Lee
    I'm running a home server on my old laptop (atom cpu). I installed ubuntu 12.04 server edition, but I also installed ubuntu-desktop. So, when I turn it on, ubuntu desktop is shown. I sometimes use GUI, but I want to turn the ubuntu-desktop (gnome-desktop) off when I don't use it. I think I can save resources by turning off the GUI. It's necessary since my laptop's performance is not very good and it often becomes very hot. I guess I can run ubuntu-desktop on my terminal with "startx" command. But, I don't know how to turn the X window off for a moment. Anybody have an idea? Thanks in advance.

  • How can I remove the ssh last login info?

    - by Gnijuohz
    Whenever I log into a server using ssh. The prompt gives me "last login" information. I was wondering where this information comes from. How can I remove this record so when someone else log into the same server, the person would see my login info with my ip in it? So how can I do this? For the record, I am not hacking someone's computer and the server runs Ubuntu 12.04. EDIT: which file logs this kind of information? If I find the file, then I can do anything to it as root. Thanks.

  • A font like RomanS in appearance but with support for more characters (Autocad)?

    - by kokbira
    In a Autocad 2010 installation, the standard font used is RomanS. That font is so limited on characters, so when I use "text" command I cannot add "³" on text of cubic meters measures (a "?" is displayed instead of the "³" character - see isolated text on figure below and Font characters Latin Supplement range). When I use a dimension command, like multileader, Autocad "corrects" that issue using another font that support that missing character, resulting on an awful mixture (see text on multileader below - on multileader text properties, we can see 3m{\fArial|b0|i0|c0|p34;³}). I can easily change that font with another, like Verdana, Times New Roman... that have more characters than RomanS font, but I would like to use an alternative font more like RomanS in appearance. Any help?

  • DVD ROM is not working

    - by Cyril N.
    (note: I don't know in which StackExchange site to put this question, I'll thank the moderator that will move it to a more appropriate place, if there is a S.E. available for my question). I have a DVD RW drive that is well listed in the bios, and if no CD is in, it is also present in the "My Computer" of my Fedora 16. But when I put a disc on it, the icon disapear from "My Computer", and I can not do anything with this ! (Like erasing a RW disc). I'd like to boot a Fedora 17 Live CD image. I burned it on an other computer but when I try to run it in bios, nothing is done and I'm redirected to Grub of my HD.

  • excel - generate a username from a full name field

    - by mheavers
    I'm trying to generate a username using a single name field in excel which has the person's first name and last name. I'm open to what the username would be, as long as its intuitive for the user. The name fields can be tricky, as the data looks like this: Albert Abongo (2 names) Stephen Michael Essuah Ackah (4 names) Alhaji Iddrisu Abdul-KArim (3 names) I guess my ideal usernames for these people would be aabongo sackah aabdul-karim

  • Excel: How to treat multiple lines as one while sorting?

    - by crono
    I get a XLS-File as a database report. The File is in the following format: | Customer | Name | ... | Orders 1 | 6 | ... | ... | 1234 2 | | | | 4567 3 | | | | 8910 4 | 3 | ... | ... | 3210 5 | | | | 8765 6 | 1 | ... | ... | 1000 7 | | | | 1001 I need to sort this thing on a column which is only "filled" in the first line of a "record" (here: Line 1-3, 4+5, 6+7) like "Customer" in this example. Is there a way (without falling back to VBA) to keep the lines together which form a "record" while sorting on them. I know, this is abusing Excel but I have no other choise here. The expected output after sorting on "Customer" would be: | Customer | Name | ... | Orders 1 | 1 | ... | ... | 1000 2 | | | | 1001 3 | 3 | ... | ... | 3210 4 | | | | 8765 5 | 6 | ... | ... | 1234 6 | | | | 4567 7 | | | | 8910

  • How do I resolve the error "Excel found unreadable content in (filename)"?

    - by Vernon
    Has anyone else seen this? Sometimes when I open certain worksheets in Excel 2010 I see the message in the title. Excel then asks if I want to repair the file. I say "Yes" and Excel reports that the file is repaired. A log file says something about removed records. However, there does not seem to be anything missing from the file, and all sheets and VB macros in the workbook work just fine. Any suggestions?

  • Installing Linux on an Asus p8z68-m PRO Motherboard

    - by Holland
    Here is a challenge: how is this done? I've tried disabling the ASM1061 controller in the Onboard Devices section, using Wubi, booting from USB (as I don't have a DVD drive, yet), and even booting from RAID/IDE (with AHCI as the default) to do this. Still, no dice. Google shows up virtually nothing related about Linux and this mobo, apart from a people just saying "disable ASMedia" (which, I assume is the ASM1061 controller, as that's all I see - apart from the USB 3.0, which I disabled already) and it hasn't really helped much. Thus, what is wrong here? Edit My problem is that I cannot boot Linux via USB or a simple Windows installer such as Wubi (for Ubuntu). I wind up getting error messages along the lines of write cache failed, along with many other cryptic error messages similar to the following: [ 1400.351374] sd 4:0:0:0: [sdb] Test WP failed, assume Write Enabled [ 1400.353433] sd 4:0:0:0: [sdb] Asking for cache data failed [ 1400.356601] sd 4:0:0:0: [sdb] Assuming drive cache: write through This seems to be common for Asus P8Z68-M Pro motherboards, with the only notable solution being to "disable ASMedia", which, as I said before, I'm guessing is the ASM1061 controller on the motherboard. Despite already disabling this, I have tried this with both Fedora and Ubuntu without any success. I need to know what I can do about this; has anyone ran into something similar or heard about this issue before? I know these motherboards are relatively new...

  • How can I disable flashing icons on Windows 7 taskbar?

    - by Jebego
    I set my Windows 7 taskbar to auto-hide. However, sometimes when a program changes or something new happens in a program, the taskbar will show its self, and its respective taskbar icon will begin flashing orange. Here's what I'm talking about: To make the taskbar hide again, I have click on the program before I can go back to what I was doing. Anyways, I personally find this very annoying, and would love to find a way to either: Prevent the taskbar from having such alerts. Prevent the taskbar from showing its self when it has such alerts. I've searched around quite a bit, and really only found answers to this for XP. I've also found another Stack Exchange Question looking for the same thing for Windows 7. However, none of the answers to the question were really what I'm looking for. I'm not looking to hide the taskbar, or control the number of flashes. However, this answer seems to be what I'm looking for, so I downloaded and tried out the program. It works perfectly, other than the fact that the start menu icon is always shown, regardless of the taskbar being set to auto-hide. So, any ideas on how to fix this problem?

  • How to append to a file as sudo? [closed]

    - by obvio171
    Possible Duplicate: sudo unable to write to /etc/profile I want to do: echo "something" >> /etc/config_file But, since only the root user has write permission to this file, I can't do that. But this: sudo echo "something" >> /etc/config_file also doesn't work. Is there any way to append to a file in that situation without having to first open it with a sudo'd editor and then appending the new content by hand?

  • Ubuntu 9.10 freezes when HDMI port is connected

    - by Felipe Hummel
    I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. The laptop has a Intel 4500 video card. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

  • HTG Explains: What “Everything Is a File” Means on Linux

    - by Chris Hoffman
    One of the defining features of Linux and other UNIX-like operating systems is that “everything is a file.” This is an oversimplification, but understanding what it means will help you understand how Linux works. Many things on Linux appear in your file system, but they aren’t actually files. They’re special files that represent hardware devices, system information, and other things — including a random number generator. These special files may be located in pseudo or virtual file systems such as /dev, which contains special files that represent devices, and /proc, which contains special files that represent system and process information.

  • An Actionable Common Approach to Federal Enterprise Architecture

    - by TedMcLaughlan
    The recent “Common Approach to Federal Enterprise Architecture” (US Executive Office of the President, May 2 2012) is extremely timely and well-organized guidance for the Federal IT investment and deployment community, as useful for Federal Departments and Agencies as it is for their stakeholders and integration partners. The guidance not only helps IT Program Planners and Managers, but also informs and prepares constituents who may be the beneficiaries or otherwise impacted by the investment. The FEA Common Approach extends from and builds on the rapidly-maturing Federal Enterprise Architecture Framework (FEAF) and its associated artifacts and standards, already included to a large degree in the annual Federal Portfolio and Investment Management processes – for example the OMB’s Exhibit 300 (i.e. Business Case justification for IT investments).A very interesting element of this Approach includes the very necessary guidance for actually using an Enterprise Architecture (EA) and/or its collateral – good guidance for any organization charged with maintaining a broad portfolio of IT investments. The associated FEA Reference Models (i.e. the BRM, DRM, TRM, etc.) are very helpful frameworks for organizing, understanding, communicating and standardizing across agencies with respect to vocabularies, architecture patterns and technology standards. Determining when, how and to what level of detail to include these reference models in the typically long-running Federal IT acquisition cycles wasn’t always clear, however, particularly during the first interactions of a Program’s technical and functional leadership with the Mission owners and investment planners. This typically occurs as an agency begins the process of describing its strategy and business case for allocation of new Federal funding, reacting to things like new legislation or policy, real or anticipated mission challenges, or straightforward ROI opportunities (for example the introduction of new technologies that deliver significant cost-savings).The early artifacts (i.e. Resource Allocation Plans, Acquisition Plans, Exhibit 300’s or other Business Case materials, etc.) of the intersection between Mission owners, IT and Program Managers are far easier to understand and discuss, when the overlay of an evolved, actionable Enterprise Architecture (such as the FEA) is applied.  “Actionable” is the key word – too many Public Service entity EA’s (including the FEA) have for too long been used simply as a very highly-abstracted standards reference, duly maintained and nominally-enforced by an Enterprise or System Architect’s office. Refreshing elements of this recent FEA Common Approach include one of the first Federally-documented acknowledgements of the “Solution Architect” (the “Problem-Solving” role). This role collaborates with the Enterprise, System and Business Architecture communities primarily on completing actual “EA Roadmap” documents. These are roadmaps grounded in real cost, technical and functional details that are fully aligned with both contextual expectations (for example the new “Digital Government Strategy” and its required roadmap deliverables - and the rapidly increasing complexities of today’s more portable and transparent IT solutions.  We also expect some very critical synergies to develop in early IT investment cycles between this new breed of “Federal Enterprise Solution Architect” and the first waves of the newly-formal “Federal IT Program Manager” roles operating under more standardized “critical competency” expectations (including EA), likely already to be seriously influencing the quality annual CPIC (Capital Planning and Investment Control) processes.  Our Oracle Enterprise Strategy Team (EST) and associated Oracle Enterprise Architecture (OEA) practices are already engaged in promoting and leveraging the visibility of Enterprise Architecture as a key contributor to early IT investment validation, and we look forward in particular to seeing the real, citizen-centric benefits of this FEA Common Approach in particular surface across the entire Public Service CPIC domain - Federal, State, Local, Tribal and otherwise.

  • How to export ECC key and Cert from NSS DB and import into JKS keystore and Oracle Wallet

    How to export ECC key and Cert from NSS DB and import into JKS keystore and Oracle Wallet In this blog I will write about how to extract a cert and key from NSS Db and import it to a JKS Keystore and then import that JKS Keystore into Oracle Wallet. 1. Set Java Home I pointed it to JRE 1.6.0_22 $ export JAVA_HOME=/usr/java/jre1.6.0_22/ 2. Create a self signed ECC cert in NSS DB I created NSS DB with self signed ECC certificate. If you already have NSS Db with ECC cert (and key) skip this step. $export NSS_DIR=/export/home/nss/ $$NSS_DIR/certutil -N -d . $$NSS_DIR/certutil -S -x -s "CN=test,C=US" -t "C,C,C" -n ecc-cert -k ec -q nistp192 -d . 3.

  • NoSQL Java API for MySQL Cluster: Questions & Answers

    - by Mat Keep
    The MySQL Cluster engineering team recently ran a live webinar, available now on-demand demonstrating the ClusterJ and ClusterJPA NoSQL APIs for MySQL Cluster, and how these can be used in building real-time, high scale Java-based services that require continuous availability. Attendees asked a number of great questions during the webinar, and I thought it would be useful to share those here, so others are also able to learn more about the Java NoSQL APIs. First, a little bit about why we developed these APIs and why they are interesting to Java developers. ClusterJ and Cluster JPA ClusterJ is a Java interface to MySQL Cluster that provides either a static or dynamic domain object model, similar to the data model used by JDO, JPA, and Hibernate. A simple API gives users extremely high performance for common operations: insert, delete, update, and query. ClusterJPA works with ClusterJ to extend functionality, including - Persistent classes - Relationships - Joins in queries - Lazy loading - Table and index creation from object model By eliminating data transformations via SQL, users get lower data access latency and higher throughput. In addition, Java developers have a more natural programming method to directly manage their data, with a complete, feature-rich solution for Object/Relational Mapping. As a result, the development of Java applications is simplified with faster development cycles resulting in accelerated time to market for new services. MySQL Cluster offers multiple NoSQL APIs alongside Java: - Memcached for a persistent, high performance, write-scalable Key/Value store, - HTTP/REST via an Apache module - C++ via the NDB API for the lowest absolute latency. Developers can use SQL as well as NoSQL APIs for access to the same data set via multiple query patterns – from simple Primary Key lookups or inserts to complex cross-shard JOINs using Adaptive Query Localization Marrying NoSQL and SQL access to an ACID-compliant database offers developers a number of benefits. MySQL Cluster’s distributed, shared-nothing architecture with auto-sharding and real time performance makes it a great fit for workloads requiring high volume OLTP. Users also get the added flexibility of being able to run real-time analytics across the same OLTP data set for real-time business insight. OK – hopefully you now have a better idea of why ClusterJ and JPA are available. Now, for the Q&A. Q & A Q. Why would I use Connector/J vs. ClusterJ? A. Partly it's a question of whether you prefer to work with SQL (Connector/J) or objects (ClusterJ). Performance of ClusterJ will be better as there is no need to pass through the MySQL Server. A ClusterJ operation can only act on a single table (e.g. no joins) - ClusterJPA extends that capability Q. Can I mix different APIs (ie ClusterJ, Connector/J) in our application for different query types? A. Yes. You can mix and match all of the API types, SQL, JDBC, ODBC, ClusterJ, Memcached, REST, C++. They all access the exact same data in the data nodes. Update through one API and new data is instantly visible to all of the others. Q. How many TCP connections would a SessionFactory instance create for a cluster of 8 data nodes? A. SessionFactory has a connection to the mgmd (management node) but otherwise is just a vehicle to create Sessions. Without using connection pooling, a SessionFactory will have one connection open with each data node. Using optional connection pooling allows multiple connections from the SessionFactory to increase throughput. Q. Can you give details of how Cluster J optimizes sharding to enhance performance of distributed query processing? A. Each data node in a cluster runs a Transaction Coordinator (TC), which begins and ends the transaction, but also serves as a resource to operate on the result rows. While an API node (such as a ClusterJ process) can send queries to any TC/data node, there are performance gains if the TC is where most of the result data is stored. ClusterJ computes the shard (partition) key to choose the data node where the row resides as the TC. Q. What happens if we perform two primary key lookups within the same transaction? Are they sent to the data node in one transaction? A. ClusterJ will send identical PK lookups to the same data node. Q. How is distributed query processing handled by MySQL Cluster ? A. If the data is split between data nodes then all of the information will be transparently combined and passed back to the application. The session will connect to a data node - typically by hashing the primary key - which then interacts with its neighboring nodes to collect the data needed to fulfil the query. Q. Can I use Foreign Keys with MySQL Cluster A. Support for Foreign Keys is included in the MySQL Cluster 7.3 Early Access release Summary The NoSQL Java APIs are packaged with MySQL Cluster, available for download here so feel free to take them for a spin today!

  • LiveMeeting VC PowerShell PASS – Troubleshooting SQL Server with PowerShell

    - by Laerte Junior
    Guys, join me on Wednesday July 18th 12 noon EDT (GMT -4) for a presentation called Troubleshooting SQL Server With PowerShell. It will be in English, so please make allowances for this. I’m sure that you’re aware that my English is not perfect, but it is not so bad. I will do my best, you can be sure. The registration link will be available soon from PowerShell.sqlpass.org, so I hope to see you there. It will be a session without slides. Just code; pure PowerShell code. Trust me, We will see a lot of COOL stuff.Big thanks to Aaron Nelson (@sqlvariant) for the opportunity! Here are some more details about the presentation: “Troubleshooting SQL Server with PowerShell – The Next Level’ It is normal for us to have to face poorly performing queries or even complete failure in our SQL server environments. This can happen for a variety of reasons including poor Database Designs, hardware failure, improperly-configured systems and OS Updates applied without testing. As Database Administrators, we need to take precaution to minimize the impact of these problems when they occur, and so we need the tools and methodology required to identify and solve issues quickly. In this Session we will use PowerShell to explore some common troubleshooting techniques used in our day-to-day work as s DBA. This will include a variety of such activities including Gathering Performance Counters in several servers at the same time using background jobs, identifying Blocked Sessions and Reading & filtering the SQL Error Log even if the Instance is offline The approach will be using some advanced PowerShell techniques that allow us to scale the code for multiple servers and run the data collection in asynchronous mode.

  • Are JSP and Java still relevant?

    - by dyyyy
    I've been working so long in java and jsp, that for me it's a no-brainer to use it. But now as I'm starting to do my own framework for web applications, I'm wondering if jsp is the right choice. Seing how much php is popular (as well as other languages as ruby and python) Is JSP still a relevant language. Does it have any clear advantage over other languages ? I don't want to use it just because i know it better. So please considering I know nothing, is there a reason to use JSP and JAVA? Thank you
