  • What are the advantages of programming to under an OS as opposed to bare metal executive?

    - by gby
    Assume you are presented with an embedded system application to program, in C, on a multi-core environment (think a Cavium or Tilera) and need to choose between two environments: Code the application under Linux in SMP mode or code the application under a thin bare metal executive (something like a very minimal RTOS), perhaps with a single core running UP Linux that can serve control tasks. For the purpose of this question, assume that both environment provide the same level of performance guarantees in any measurable aspects of run time performance, including number of meaningful action per second, jitter, latency, real time considerations - the works. (and yes, I realize this is by far not a trivial assumption at all, bare with me). How would you justify going with a Linux SMP based solution rather then a bare metal thin executive solution? The question may seems silly. It certainly seems obvious to me - but I have to convince someone that does not think the same. Could you help make a list of arguments in favor of choosing a real SMP aware OS (Linux) vs. a bare metal executive assuming performance guarantees are NOT an issue? Many thanks

  • How to make a good portfolio for IT student (who loves programming) like me?

    - by Viet
    I am currently a college student, and going to apply for an university in probably next month. Unlike art student who easily put on their works such as models, designs and so on on their portfolio; I am hitting a dead corner trying to find a "creative" way to showcase my work as a programmer. It would be normal if programmer shows his good project with source code and everything else. Well, it should be no problem with actual "good" projects, but all of my projects are crappy (can't help it because I am still student, and don't have much work experience) and I don't even know it's worth to show. Nonetheless, I have learned a lot in only 1 year since I started programming. I am now familiar with Java, PHP, Actionscript3, C#, Objective-C and on my way to learn Ruby. I plan to build a Flash portfolio using Actionscript with Ruby as backend to show what I have learnt. The problem is idea. How to show people that I learned a lot of useful thing? Otherwise I hit the dead end and LOL just show what I have on Github (but i certainly never want that...)

  • creating a tag-based website and not using programming?

    - by monodial
    I want to create a tag-based website, and I need a tool that I could use (preferably without programming). It's a site where a user could pick tags on a certain item. All tags will be placed under a group that they are logically linked to (I will do that by hand). On the other end - a visitor could choose a tag, and then be redirected to a few items on which that tag was selected the most. Besides this, I need to set up a registration form (for the visitors who want to select tags on a desired item). stackoverflow.com may serve as an example of what I want to achieve. Functionally it is a quite similar approach. I am not sure if further detailing will bring me closer to getting a development advice, but nevertheless - following this template what I would be missing on is: ability to categorize the tags; and so they would fit in one page (overall i assume <200 tags) box where a user could enter a tag and it would be pending until a certain number of users enter such tag ability to limit the number of 'questions' that appear when a visitor chooses a tag - 'question' stands for an item to which users are selecting tags (displayed items would depend on the frequency the tag was assigned - say the top two items) Which software should I try / How should I go about it? Thank you. Lukas P.S. I have bought hosting account through GoDaddy.com. This is a first website that I am trying to build.

  • How do you compare programming job offers from companies in different countries?

    - by Danny Tuppeny
    This isn't really a programmer-specific question, but I'm not sure of a more appropriate place, and I think the users of this site are best able to answer the question in the context of programmers. Relocating to the US seems fairly common in the programming industry. I live in the UK, and maybe one day, I might do it too. So, if that day comes - how would you go about comparing job offers? Benefits are fairly easy to compare, but given the differences in cost of living, how would you go about comparing salaries and the quality of living you'll have? In a country where the cost of living is lower, you might be able to accept a lower salary (based on exchange rate) and still have the same quality of living. But what can you do to ensure this? In some cases, you may even take a "pay rise" in terms of exchange rate, but end up far worse off. How can you compare job offers across different countries to get an idea of the salary you would need in order to not feel you've gone "backwards"?

  • Is there a common programming term for the problems of adding features to an already-featureful program?

    - by Jeremy Friesner
    I'm looking for a commonly used programming term to describe a software-engineering phenomenon, which (for lack of a better way to describe it) I'll illustrate first with a couple of examples-by-analogy: Scenario 1: We want to build/extend a subway system on the outskirts of a small town in Wyoming. There are the usual subway-problems to solve, of course (hiring the right construction company, choosing the best route, buying the subway cars), but other than that it's pretty straightforward to implement the system because there aren't a huge number of constraints to satisfy. Scenario 2: Same as above, except now we need to build/extend the subway system in downtown Los Angeles. Here we face all of the problems we did in case (1), but also additional problems -- most of the applicable space is already in use, and has a vocal constituency which will protest loudly if we inconvenience them by repurposing, redesigning, or otherwise modifying the infrastructure that they rely on. Because of this, extensions to the system happen either very slowly and expensively, or they don't happen at all. I sometimes see a similar pattern with software development -- adding a new feature to a small/simple program is straightforward, but as the program grows, adding further new features becomes more and more difficult, if only because it is difficult to integrate the new feature without adversely affecting any of the large number of existing use-cases or user-constituencies. (even with a robust, adaptable program design, you run into the problem of the user interface becoming so elaborate that the program becomes difficult to learn or use) Is there a term for this phenomenon?

  • English major new to programming. What language should I learn first? [closed]

    - by PJKaka
    After working extensively an internet startup in a marketing positions, I've decided to wade into the entrepreneurship pool with a startup of my own. The only problem: I don't have any particular technical skills to speak of. Although I can find a technical co-founder, I'd rather not be the stereotypical 'business guy' drumming his fingers on the desk and asking 'how much longer?' as my technical co-founder codes away. I would like to understand code and what's happening in the backend, even if I don't end up being anything more than a 'passable' programmer. With this in mind, which language should I try to learn first? For the record, I'm quite proficient with HTML, CSS, and a bit of JavaScript. I have some familiarity with PHP because I've toyed around with WordPress a lot, but my knowledge is limited at best. My math skills are quite strong. I took some advanced calculus courses in college since I've always enjoyed the subject. While my goals are to learn web development, I wouldn't mind learning some hardcore object oriented programming skills in C or Java as well.

  • Is embedded programming closer to electrical engineering or software development?

    - by Jeremy Heiler
    I am being approached with a job for writing embedded C on micro controllers. At first I would have thought that embedding programming is to low on the software stack for me, but maybe I am thinking about it wrong. Normally I would have shrugged off an opportunity to write embedded code, as I don't consider myself an electrical engineer. Is this a bad assumption? Am I able to write interesting and useful software for embedded systems, or will I kick myself for dropping too low on the software stack? I went to school for computer science and really enjoyed writing a compiler, managing concurrent algorithms, designing data structures, and developing frameworks. However, I am currently employed as a Flex developer, which doesn't scream the interesting things I just described. (I currently deal with issues like: "this check box needs to be 4 pixels to the left" and "this date is formatted wrong".) I appreciate everyone's input. I know I have to make the decision for myself, I just would like some clarification on what it means to be a embedded programmer, and if it fits what I find to be interesting.

  • How to search the web for programming related solutions?

    - by Bob
    I have the impression that Google has become unusable when searching for programming related questions. Example: I'm Googling for XML-RPC Redstone Cookie I'm expecting results where all three terms are contained. I don't care for results where one term misses. I guess until some months ago Google just worked this way, i.e. all terms were included. Somehow this feature is gone now (Google apparently thinks it is more intelligent than the user and knows what the user is searching for). So I helped myself putting a + in front of every word. This is, however, a bit cumbersome. And for the last weeks, it even doesn't work anymore in all cases, Google ignores the +. So how do you search for progamming related problems? Do you still use Google? If yes, which techniques do you use to get the right results? Or do you use another search engine? Which one?

  • How come there is still so much programming work?

    - by jd_505
    First I'd like to say that I am not pretty sure that this question will meet the guidelines. I think it can goes under the "Freelancing and business concerns" bullet, but I am not sure. Anyway, I will give it a shot. I wonder how the programming jobs hasn't yet "dried" because of the software evolution, for example, I am a developer myself, which means that I do care about software (I mean I am not of the type of guys that needs a computer mainly to just browse the Internet), and still I wouldn't mind if I never receive any more updates on my Ubuntu machine. I find that it provides everything I need, and while the updates provide various bug fixes/improvements, I wouldn't mind using it with it's current state for the rest of my life, for 2 years of Ubuntu usage I have never bumped at a serious bug/problem. Another example is Windows, almost half of it's users still use XP, which is practically ancient, yet they find it satisfying all their needs (and I agreee with them). I could go with many more examples, but by now you are understanding my point and my question. While new "trends" appears all of the time (like a new mobile OS) which runs on new platforms and requires some fresh development work, still the majority of the software effort goes in to what I consider as "completed projects", or at least a state of a project which is enough to be considered as completed. Do you have an explanation ? I can't think of the right tags for this question, please edit it the way you find it to be most appropriate. Thanks.

  • How complex/straightforward should my programming challenge response in an interview be? [closed]

    - by atraudes
    I've had a couple of interviews for programmer positions in the past couple of weeks, and just about all of them have presented me with programming challenges. Write a program with XX language that can solve XX puzzle or problem, etc. I've had no problem answering the questions. What I'm unsure about is what the depth and breadth my response should be. What would an ideal response look like? How much oomph and time should I spend on elements of the code that aren't crucial to it running (Comments, Javadoc, error handling, etc.)? What if I have 1 hour/6 hours/a whole weekend to spend on it? What are the most important aspects of my response to the interviewer? What's worked for you in the past or what worked on you as an interviewer? I'm definitely one of those folks that can go all out on a project and make it truly shine, but I don't want to give them the impression that I'm going to waste their time and money on stuff they may not want or care about. I have a sneaking feeling there is no "wrong" way to respond to the challenge; each response has a redeeming quality about it, and the goals of the interview are subjective. Regardless, I would love your thoughts and input on this.

  • IPsec tunnel to Android device not created even though there is an IKE SA

    - by Quentin Swain
    I'm trying to configure a VPN tunnel between an Android device running 4.1 and a Fedora 17 Linux box running strongSwan 5.0. The device reports that it is connected and strongSwan statusall returns that there is an IKE SA, but doesn't display a tunnel. I used the instructions for iOS in the wiki to generate certificates and configure strongSwan. Since Android uses a modified version of racoon this should work and since the connection is partly established I think I am on the right track. I don't see any errors about not being able to create the tunnel. This is the configuration for the strongSwan connection conn android2 keyexchange=ikev1 authby=xauthrsasig xauth=server left=96.244.142.28 leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=%any rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem ike=aes256-sha1-modp1024 auto=add This is the output of strongswan statusall Status of IKE charon daemon (strongSwan 5.0.0, Linux 3.3.4-5.fc17.x86_64, x86_64): uptime: 20 minutes, since Oct 31 10:27:31 2012 malloc: sbrk 270336, mmap 0, used 198144, free 72192 worker threads: 8 of 16 idle, 7/1/0/0 working, job queue: 0/0/0/0, scheduled: 7 loaded plugins: charon aes des sha1 sha2 md5 random nonce x509 revocation constraints pubkey pkcs1 pkcs8 pgp dnskey pem openssl fips-prf gmp xcbc cmac hmac attr kernel-netlink resolve socket-default stroke updown xauth-generic Virtual IP pools (size/online/offline): android-hybrid: 1/0/0 android2: 1/1/0 Listening IP addresses: 96.244.142.28 Connections: android-hybrid: %any...%any IKEv1 android-hybrid: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android-hybrid: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android-hybrid: remote: [%any] uses XAuth authentication: any android-hybrid: child: dynamic === dynamic TUNNEL android2: 96.244.142.28...%any IKEv1 android2: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android2: remote: [C=CH, O=strongSwan, CN=client] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=client" android2: remote: [%any] uses XAuth authentication: any android2: child: 0.0.0.0/0 === 10.0.0.0/24 TUNNEL Security Associations (1 up, 0 connecting): android2[3]: ESTABLISHED 10 seconds ago, 96.244.142.28[C=CH, O=strongSwan, CN=vpn.strongswan.org]...208.54.35.241[C=CH, O=strongSwan, CN=client] android2[3]: Remote XAuth identity: android android2[3]: IKEv1 SPIs: 4151e371ad46b20d_i 59a56390d74792d2_r*, public key reauthentication in 56 minutes android2[3]: IKE proposal: AES_CBC_256/HMAC_SHA1_96/PRF_HMAC_SHA1/MODP_1024 The output of ip -s xfrm policy src ::/0 dst ::/0 uid 0 socket in action allow index 3851 priority 0 ptype main share any flag (0x00000000) lifetime config: limit: soft 0(bytes), hard 0(bytes) limit: soft 0(packets), hard 0(packets) expire add: soft 0(sec), hard 0(sec) expire use: soft 0(sec), hard 0(sec) lifetime current: 0(bytes), 0(packets) add 2012-10-31 13:29:08 use -

  • Spring @Transactional not creating required transaction

    - by Steve
    Ok, so I've finally bowed to peer pressure and started using Spring in my web app :-)... So I'm trying to get the transaction handling stuff to work, and I just can't seem to get it. My Spring configuration looks like this: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean id="groupDao" class="mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao" lazy-init="true"> <property name="entityManagerFactory" ><ref bean="entityManagerFactory"/></property> </bean> <!-- enables interpretation of the @Required annotation to ensure that dependency injection actually occures --> <bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/> <!-- enables interpretation of the @PersistenceUnit/@PersistenceContext annotations providing convenient access to EntityManagerFactory/EntityManager --> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/> <!-- uses the persistence unit defined in the META-INF/persistence.xml JPA configuration file --> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="CONOPS_PU" /> </bean> <!-- transaction manager for use with a single JPA EntityManagerFactory for transactional data access to a single datasource --> <bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <!-- enables interpretation of the @Transactional annotation for declerative transaction managment using the specified JpaTransactionManager --> <tx:annotation-driven transaction-manager="jpaTransactionManager" proxy-target-class="true"/> </beans> persistence.xml: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="CONOPS_PU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> ...

  • JSF 1.1 and Ajax4jsf not working properly on Websphere 6.1

    - by Shamik
    I am working with JSF 1.1, Ajax4JSF. What I find is if I enable a4j:support for some of JSF's inputText items, it is not working as expected. I have something like this in the code <h:inputText value="#{bean.desc}"> <a4j:support event="onkeyup" reRender="id"/> </h:inputText> And what I find is, sometimes it does not work, for example, I type TEST on the input text box and what transfers is only the "T" to the backing bean. One more problem that I see is, when I submit the form, some of the values are not getting set in the backing bean. The setter methods are not called at all. I do not think this is working properly in my env, is it this combination of JSF1.1,Ajax4JSF and websphere6.1 is not supported or is there anyway I can troubleshoot this ?

    I've gone through the steps to set up and install the redmine project tracking web app on my VPS with Apache2 but I'm running into a situation where instead of displaying the redmine app, I just see the directory contents: Does anyone know what could be the problem? I'm not sure what other files might be of use to diagnose what's going on. Thanks! # # Based upon the NCSA server configuration files originally by Rob McCool. # # This is the main Apache server configuration file. It contains the # configuration directives that give the server its instructions. # See http://httpd.apache.org/docs/2.2/ for detailed information about # the directives. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # The configuration directives are grouped into three basic sections: # 1. Directives that control the operation of the Apache server process as a # whole (the 'global environment'). # 2. Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log" # with ServerRoot set to "" will be interpreted by the # server as "//var/log/apache2/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE! If you intend to place this on an NFS (or otherwise network) # mounted filesystem then please read the LockFile documentation (available # at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>); # you will save yourself a lot of trouble. # # Do NOT add a slash at the end of the directory path. # ServerRoot "/etc/apache2" # # The accept serialization lock file MUST BE STORED ON A LOCAL DISK. # #<IfModule !mpm_winnt.c> #<IfModule !mpm_netware.c> LockFile /var/lock/apache2/accept.lock #</IfModule> #</IfModule> # # PidFile: The file in which the server should record its process # identification number when it starts. # This needs to be set in /etc/apache2/envvars # PidFile ${APACHE_PID_FILE} # # Timeout: The number of seconds before receives and sends time out. # Timeout 300 # # KeepAlive: Whether or not to allow persistent connections (more than # one request per connection).

  • How to troubleshoot problem with OpenVpn Appliance Server not able to connect

    - by Peter
    1) I have a Windows Server 2008 Standard SP2 2) I am running Hyper-V and have the OpenSvn Appliance Server virtual running 3) I have configured it as it said, only issue was that the legacy network adapter does not have a setting the instructions mention "Enable spoofing of MAC Addresses". My understand is that before R2, this was on by default. 4) Server is running, web interfaces look good 5) I am trying to connect from a Vista 64 box and cannot 5a) If I set to UPD I am stuck at Authorizing and client log looks like: 10/11/09 15:00:42: INFO: OvpnConfig: connect... 10/11/09 15:00:42: INFO: Gui listen socket at 34567 10/11/09 15:00:42: INFO: sending start command to instantiator... 10/11/09 15:00:42: INFO: start 34567 ?C:\Users\Peter\AppData\Roaming\OpenVPNTech\config?02369512D0C82A04B88093022DA0226202218022A902264022AE022B? 10/11/09 15:00:42: INFO: Got line from MI->>INFO:OpenVPN Management Interface Version 1 -- type 'help' for more info 10/11/09 15:00:42: INFO: Got line from MI->>HOLD:Waiting for hold release 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: real-time state notification set to ON 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: bytecount interval changed 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: hold flag set to OFF 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: hold release succeeded 10/11/09 15:00:43: INFO: Got line from MI->>PASSWORD:Need 'Auth' username/password 10/11/09 15:00:43: INFO: Processing PASSWORD. 10/11/09 15:00:43: INFO: OvpnClient: setting need auth to true. 10/11/09 15:00:43: INFO: OvpnConfig: Setting need auth to true. 10/11/09 15:00:43: INFO: Got auth request from active_config from 0 10/11/09 15:00:47: INFO: Sending Credentials.... 10/11/09 15:00:47: INFO: Sending 25 bytes for username. 10/11/09 15:00:47: INFO: Sent 25 bytes for username. 10/11/09 15:00:47: INFO: Sending 30 bytes for password. 10/11/09 15:00:47: INFO: Sent 30 bytes for password. 10/11/09 15:00:48: INFO: Got line from MI->SUCCESS: 'Auth' username entered, but not yet verified 10/11/09 15:00:48: INFO: Got line from MI->SUCCESS: 'Auth' password entered, but not yet verified 10/11/09 15:00:48: INFO: Got line from MI->>STATE:1255287647,WAIT,,, 10/11/09 15:00:48: INFO: Got line from MI->>BYTECOUNT:0,42 10/11/09 15:00:48: INFO: Got line from MI->>BYTECOUNT:54,42 10/11/09 15:00:48: INFO: Got line from MI->>STATE:1255287648,AUTH,,, 10/11/09 15:00:50: INFO: Got line from MI->>BYTECOUNT:2560,2868 10/11/09 15:00:52: INFO: Got line from MI->>BYTECOUNT:2560,3378 5b) I setup server for tcp and try to connect, I get a loop of authorizing and reconnecting.

  • DNSSEC - Ad Flag not activated

40,000 and 1,500,000 numbers in the same range with and added _ and a 1-999 suffix numbers in the same range prefixed with BLA Each value is present exactly twice. There are no formula involved. I already checked for extra spaces. Immediately reapplying the Remove Duplicates command does not remove the remaining duplicate values. Reapplying the Remove Duplicates command after a reverse-sort seems to remove the remaining duplicates. Reverse-sorting before using the first Remove Duplicates changes the result (213 duplicate values removed and 387 unique values remained), only in the non-suffixed non-prefixed group. Can you reproduce this bug in Excel 2007 like I do? What triggers it? Could it the composite (numbers and text) data set? I'm not looking for alternatives. I want to know when not to use the feature and revert to already known (Excel 2003 era) alternatives.

  • Command does not execute in crontab while command itself works just fine

    - by fuzzybee
    I have this script from Colin Johnson on Github - https://github.com/colinbjohnson/aws-missing-tools/tree/master/ec2-automate-backup It seems great. I have modified it to send email to myself every time an EBS snapshot is created or deleted. The following works like a charm ec2-automate-backup.sh -v "vol-myvolumeid" -k 3 However, it does not execute at all as part of my crontab (I didn't receive any emails) #some command that got commented out */5 * * * * ec2-automate-backup.sh -v "vol-fb2fbcdf" -k 3; * * * * * date /root/logs/crontab.log; */5 * * * * date /root/logs/crontab2.log Please note that the 2nd and 3rd execute just fines as I can see the date and time in log files. What could I have missed here?

  • unattended-upgrades does not reboot

    - by Cheiron
    I am running Debian 7 stable with unattended-upgrades (every morning at 6 AM) to make sure I am always fully updated. I have the following config: $ cat /etc/apt/apt.conf.d/50unattended-upgrades // Automatically upgrade packages from these origin patterns Unattended-Upgrade::Origins-Pattern { // Archive or Suite based matching: // Note that this will silently match a different release after // migration to the specified archive (e.g. testing becomes the // new stable). "o=Debian,a=stable"; "o=Debian,a=stable-updates"; // "o=Debian,a=proposed-updates"; "origin=Debian,archive=stable,label=Debian-Security"; }; // List of packages to not update Unattended-Upgrade::Package-Blacklist { // "vim"; // "libc6"; // "libc6-dev"; // "libc6-i686"; }; // This option allows you to control if on a unclean dpkg exit // unattended-upgrades will automatically run // dpkg --force-confold --configure -a // The default is true, to ensure updates keep getting installed //Unattended-Upgrade::AutoFixInterruptedDpkg "false"; // Split the upgrade into the smallest possible chunks so that // they can be interrupted with SIGUSR1. This makes the upgrade // a bit slower but it has the benefit that shutdown while a upgrade // is running is possible (with a small delay) //Unattended-Upgrade::MinimalSteps "true"; // Install all unattended-upgrades when the machine is shuting down // instead of doing it in the background while the machine is running // This will (obviously) make shutdown slower //Unattended-Upgrade::InstallOnShutdown "true"; // Send email to this address for problems or packages upgrades // If empty or unset then no email is sent, make sure that you // have a working mail setup on your system. A package that provides // 'mailx' must be installed. E.g. "[email protected]" Unattended-Upgrade::Mail "root"; // Set this value to "true" to get emails only on errors. Default // is to always send a mail if Unattended-Upgrade::Mail is set Unattended-Upgrade::MailOnlyOnError "true"; // Do automatic removal of new unused dependencies after the upgrade // (equivalent to apt-get autoremove) //Unattended-Upgrade::Remove-Unused-Dependencies "false"; // Automatically reboot *WITHOUT CONFIRMATION* if a // the file /var/run/reboot-required is found after the upgrade Unattended-Upgrade::Automatic-Reboot "true"; // Use apt bandwidth limit feature, this example limits the download // speed to 70kb/sec //Acquire::http::Dl-Limit "70"; As you can see Automatic-Reboot is true and thus the server should automaticly reboot. Last time I checked the server was online for over 100 days, which means that the update from Debian 7.1 to Debian 7.2 has happened while the server was up (and indeed, all updates were installed), but this involves kernel updates, which means that the server should reboot. It did not. The server was running very slow, so I rebooted which fixed that. I did some research and found out that unattended-upgrades responds to the reboot-required file in /var/run/. I touched this file and waited one week, the file still exists and the server did not reboot. So I think that unattended-uppgrades ignores the auto-reboot part. So, am I doing somthing wrong here? Why did the server not restart? The upgrade part works perfect by the way, its just the reboot part that does not seem to work as it should.

  • Using different SSDs types (not only SATA based) as system drive

    - by Hubert Kario
    Currently I have a Thinkpad X61s and want to make it both a bit faster and a bit more power efficient. For that reason I thought that adding SSD drive would make most sense. Unfortunately, because of financial reasons, buying SSD of over 200GB capacity is out of reach for me (not only it would be worth more than the rest of the laptop, but also I currently have a 500GB drive in it, so even such a drive would be kind of a downgrade for me). During preliminary testing with a cheap Transcend 4GB Class 6 (14MiB/s streaming, 9MiB/s random read) card I experienced boot times to be reduced by half so putting the OS only on it would already would be an improvement. Unfortunately, my system now is about 11GiB in size so anything less than 16GB would be constraining. In this laptop I can connect additional drives on at least 5 different ways: using SATA-ATA converter caddy in the X6 Ultrabase using internal mini PCIe slot using integrated SDHC slot using CardBus (a.k.a PCMCIA or PC Card) slot using USB Thankfully, because I use only Linux on this PC the bootability of them is irrelevant as I can put the /boot partition on internal HDD and / on any of the above mentioned Flash memories (as I already did for the SDHC test). From what I was able to research and from my own experience those options come with rather big downsides or other problems: SATA-ATA caddy It has three downsides: I have to carry the Ultrabse with me at all times (it's not really inconvenient, but those grams do add) and couldn't disconnect it when I want to disconnect the battery It makes the bay unusable for the optical drive and occasional quick access to other hard drives the only caddies I could buy have rather flaky controllers in them so putting my OS on it would hamper its stability Internal mini PCIe slot This would be an ideal solution, if only I could find real PCIe SSDs, not only devices that could talk only SATA or ATA over PCIe mechanical connection (the ones used in Dell Mini or Asus EEE). Theoretically Samsung did release such devices but I couldn't find them in retail anywhere. Integrated SDHC slot It's a nice solution with a single drawback: the fastest 16GB SDHC card on the market can only do around 35MiB/s read and 15MiB/s write while still costing like a normal 40GB SATA SSD that's 10 times faster. Not really cost-effective. CardBus (a.k.a PCMCIA or PC Card) slot Those cards are much faster than the SDHC option (there are ones that can do well over 50MiB/s read in benchmarks) and from what I could find the PCMCIA controller in my laptop does support UDMA so it should be able to deliver comparable speeds. They still cost similarly to SD cards but at least they provide streaming performance comparable to my current HDD. USB That's the worst option. Not only is it limited to 20-30MiB/s by the interface itself the drive would stick out of the laptop so it's a big no no. The question As such I think that going the "CF in a CardBus adapter" route will be the best option. My question is: did anyone try using CF cards in CardBus adapters as system drives with Linux on Thinkpad laptops? Laptops in general? What was the real-world performance? I don't have any CF cards so I can't check how well does it work with suspend/resume, or whatever it's easy to make it work in initramfs (I'm using ArchLinux and SD card was trivial — add 3 modules in single config line and rebuilding initramfs) so any tips/gotchas on this are welcome as well.

  • Oracle curcular join sometimes give duplicates, but sometimes does not

    - by Kaushik
    By mistake I wrote a query like this: select * from a,b,c where a.col=b.col and b.col2=c.col2 and c.col3=a.col4 So there is a circular join here. Now the thing is sometimes this query returns duplicate result, sometimes it returns unique(correct) results. I am trying to understand why it does not give duplicate results always. Also if circular joins are not allowed, how come Oracle does not throw an error. EDIT: This is the actual query. After reading ti carefully, I am not sure anymore if this is a circular join or not.It does not seem so...but why I get duplicates only sometime? select * from a,b,c,d where a.col=b.col and b.col=c.col and c.col2=d.col2 and d.col2 =a.col2
