• Relationships in a Chen ERD

  - by Nibroc A Rehpotsirhc

  I am working on a Chen ERD to model our organizations merchandise. Our central entity is a Style. We have supplemental entities of Color and Season. I am defining our assortment as the relationship between these three entities, and this relationship itself will have attributes and is defined by the three entities which participate in the mandatory relationship. The rules are; Many Styles can be offered in a Season, and a Style can be offered in many Seasons. Within a Season, a Style can be offered in Many Colors. I then have 2 other entities, one of which I believe is a weak entity, Climate, and the other may be weak, but I am not sure, this being Transaction Channel. I am thinking of these as relationships off of a relationship? Meaning, for a given Style/Color combination offered in a Season, it can be available through 1 or more Transaction Channels. Additionally, within a season, a given Style/Color combination can be intended for 1 or more Climates. Is it valid to have relationships off of relationships? Or does this requirement dictate that I should think of this Style/Color/Season relationship as an entity itself, and define the relationships to Climate and Transaction Channel off of this entity?

• My DNS cannot resolve an web site address?

  - by ipkiss

  Hello all, Recently, I could not access the webpage bbc.co.uk anymore, while I can access other websites smoothly. Ar first, I though there may be some problem with my laptop. However, if I use my laptop through my company network, I can load the page bbc.co.uk normally. Then, I though maybe my ADSL at home blocks that web address. However, I tried another laptop with my home ADSL and it can load the page bbc.co.uk very fast. Now I do not know what could be the problem. Can anyone tell me please? Thank you.

• Wrong package for Idle-python2.7?

  - by adelval

  I'm running python 2.7 in Ubuntu 3.10, and idle (idle-python2.7) has stopped working. Whenever I try to open a file in a editor window, it is blank, though the file does exist and is not empty/blank. Furthermore, it is not possible to close idle after this, except via a terminal kill command. Idle was working fine before. The problem appeared after I installed a number of things, including idlex, various scipy modules and mpmath, but after trying to repair it in several ways, it seems to be caused by Ubuntu's official idle package. I get this error in the terminal when trying to open a file in idle: Exception in Tkinter callback [...lines ommitted for brevity...] File "/usr/lib/python2.7/idlelib/IOBinding.py", line 129, in coding_spec for line in lst: NameError: global name 'lst' is not defined If you look at the code, it looks like an obvious bug: indeed lst is not defined in the function coding_spec. Furthermore, the source file IOBinding.py in http://fossies.org/dox/Python-2.7.5/IOBinding_8py_source.html is different and doesn't show the problem. Thinking that one of the recently packages had overwritten the file somehow, I've tried a number of things, including reinstalling all Python packages from synaptic, but the wrong IOBinding.py is still there. The reason I think the problem lies with the package itself is that I finally did sudo apt-get remove idle, verified that the idlelib directory was empty, and reinstalled with sudo apt-get install idle; but the wrong IOBinding.py file came back again. I can in fact make idle work again by simply replacing lst by str in the code, but to me that's clearly a no-no. I'm not to happy either about trying to replace just that file from the source python distribution, as other files may be wrong. I want to get the right files from the official package.

• Monitoring remote laptops

  - by kaerast

  We're looking for something to monitor around 30 remote laptops that are constantly out on the road, never returning to base except for when there are serious hardware faults that need repairing. These laptops won't always be connected to the internet, they'll have mobile broadband and may work offline most of the time. They will be running a mixture of Windows XP, Vista and 7 and there is currently no server setup. We're primarily interested in making sure that Windows Updates and antivirus updates are happening, and I guess we should also be monitoring remaining disk space, what software is installed and ideally hardware health. It might also be nice if we could gain remote access to perform work on them. My main reason for wanting to monitor them is that it's going to be a real pain to get them back to base if anything goes wrong, so I want to be proactive in ensuring they last as long as possible. Can you recommend what I should be monitoring to ensure a long life? What tools would you use to monitor and maintain these computers?

• Canon MG6100 series USB Printer not mounting

  - by user35201

  Printer MP6150 driver installed itself upon plugging in the printer. Printer is recognized (lsusb shows it) but does not mount.

• Upcoming Events

  - by noreply(at)blogger.com (Thomas Kyte)

  I'll be doing four public events in the next week and a half or so. The first one is open to anyone - anywhere.  I'll be doing a live webinar on MAA - the Maximum Availability Architecture.  It will take place this Thursday April 12th at 10am PDT.  You should register online before then if you are interested.After that, I'll be off to Belfast Ireland to do a repeat of what I presented at Oracle OpenWorld in October.  This will be done in conjunction with Oracle and the UKOUG.  See http://www.ukoug.org/events/tom-kyte-seminar-and-asktom-live/ for details, it'll take place on Monday April 16th.When I'm done in Ireland - I'll be doing it all over again in London on Wednesday April 18th.  This is being put on by the UKOUG and details may be found here http://www.ukoug.org/events/tom-kyte-seminar/.Lastly - I'll be going from London to Las Vegas for IOUG's Collaborate.  I'll be doing a day of Real World Performance with Andrew Holdsworth and Graham Wood.  If you are going to Collaborate and want to spend all day Sunday in a technical session (probably cheaper than the tables....) - you might want to check it out.  Details on the session can be found here: http://events.ioug.org/p/cm/ld/fid=31#realHope to see you at one of the events... (well, I won't really see anyone at the first event but you know what I mean)

• What is the difference between /sbin/nologin and /bin/false?

  - by Michael Hampton

  I have often heard it recommended that a user account should be disabled by setting its shell to /bin/false. But, on my existing Linux systems, I see that a great number of existing accounts (all of them service accounts) have a shell of /sbin/nologin instead. I see from the man page that /sbin/nologin prints a message to the user saying the account is disabled, and then exits. Presumably /bin/false would not print anything. I also see that /sbin/nologin is listed in /etc/shells, while /bin/false is not. The man page says that FTP will disable access for users with a shell not listed in /etc/shells and implies that other programs may do the same. Does that mean that somebody could FTP in with an account that has /sbin/nologin as its shell? What is the difference here? Which one of these should I use to disable a user account, and in what circumstances? What other effects does a listing in /etc/shells have?

• Migrating Forms to Java or ADF, the truth and no FUD

  - by Grant Ronald

  The question about migrating Forms to Java (or ADF or APEX) comes up time and time again.  I wanted to pull some core information together in a single blog post to address this question. The first question I always ask is "WHY" - Forms may still be a viable option for you so "if it ain't broke don't fix it".  Bottom line is whatever anyone tells you, its going to be a considerable effort and cost to migrate from Forms to something else so the business is going to want to know WHY you spend all those hard earned dollars switching from something that might have been serving you quite adequately. Second point, if you are going to switch, I would encourage you NOT to look at building a Forms clone.  So many times I see people trying to build an ADF application and EXACTLY mimic the Forms model - ADF is NOT a Forms clone.  You should be building to the sweet spot of your target technology, not your 20 year old client/server technology.  This is also the chance for the business to embrace change, so maybe look at new processes, channels and technology options that weren't available when you first developed your Forms applications. To help you understand what is involved, I've put together a number of resources. Thinking about migration of Forms to Java, ADF or APEX, read this to prepare yourself Oracle Forms to ADF: When, Why and How - this gives you an overview of our vision, directly from Oracle Product Management Redeveloping a Forms Application with Oracle JDeveloper and Oracle ADF.  This is a conference session from myself and Lynn Munsinger on how ADF can be used in a Forms migration/rewrite As someone who manages both Forms and ADF Product Management teams, I've a foot in either camp and am happy to see you use either tool.  However, I want you to be able to make an informed decision.  My hope is that there information sources will help you do that.

• Modernising settings, packages

  - by Sam Brightman

  The update manager (possibly combined with the janitor) does a reasonable job of bringing packages up to date with a new release, removing ones that are replaced by different projects etc. However, I'm left with the lingering feeling that quite a few settings are lingering from old releases. For example, some packages may be left around that I installed myself whereas now the functionality is provided by default. Another example is that my user doesn't get the new theme, and the panel bar is a mess. I can compare against an inactive user on the same system: everything seems tidier. There are also things like the explosion of System Preferences, user groups (inactive user, more recently created, is in groups that the older, active user isn't). In other areas (e.g. default font) I do seem to get given the new defaults. Another example is Spotlight-equivalent search. I remember Beagle and Tracker, I remember removing tracker when it used all system RAM and swap for 2 entire release cycles, but I don't know what I'm "supposed" to be using now. Is there even a default indexing-search installed and exposed? aptitude install ubuntu-desktop doesn't do anything, so the basics are in place package-wise. Is there any way to update my settings to the modern "Ubuntu way" without reinstalling from scratch? Can I do so selectively i.e. show the differences? Most of the time package management on Linux is an absolute joy compared to the alternatives, but if the desktop gets messed up after only a release or two, we're back to reinstalling just like Windows.

• Team Foundation Server 2010 and Sharepoint/WSS3.0

  - by Liam

  As I'm new to Team Foundation Server, this may seem a bit of a daft question but I have been tasked with installing TFS2010. What I want to know is, do I have to have a full version of MOSS 2007 installed to build a project dashboard for TFS or can I get away with just using WSS 3.0 that comes with TFS? Having looked through the docs for TFS, I get the idea that I have to have a full Sharepoint installation somewhere. Though I'd like this to be clarified if possible. Thanks in advance.

• "Recipient address rejected" when sending an email to an external address with sendgrid

  - by WJB

  In postfix, I'm using relay_host to send an email to an external address using sendgrid, but I get an error about local ricipient table when sending an email from my PHP code. This is my main.cf in /postfix/ ## -- Sendgrid smtp_sasl_auth_enable = yes smtp_sasl_password_maps = static:username:password smtp_sasl_security_options = noanonymous smtp_tls_security_level = may header_size_limit = 4096000 relayhost = [smtp.sendgrid.net]:587 This is the error message from the log: postfix/smtpd[53598]: [ID 197553 mail.info] NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 550 5.1.1 Recipient address rejected: User unknown in local recipient table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<localhost.localdomain> One interesting thing is when I use "sendmail [email protected]" from the command line, the email is delivered successfully using SendGrid. I think it's because this uses postfix/smtp instead of postfix/smtpD the log for this says, postfix/smtp[18670]: [ID 197553 mail.info] AAF7313A7E: to=, relay=smtp.sendgrid.net[50.97.69.148]:587, delay=4.1, delays=3.5/0.02/0.44/0.18, dsn=2.0.0, status=sent (250 Delivery in progress) Thank you

• JDK 7 Feature Complete Milestone Reached

  - by Henrik Ståhl

  The JDK 7 project has reached Feature Complete (FC). This means that development and QA have finished all planned feature and test development work in the release and are moving the focus to testing and bug fixing on all supported JDK 7 platforms. This is a major step towards JDK 7 General Availability (GA) and implies that we are tracking close to the plan published on openjdk.java.net. (The original plan was FC on 12/16. We hit this less than a week late, but verifying that everything was done in time took a couple of weeks due to the intervening holidays.) The definition of the FC milestone allows for exceptions to be integrated later. There are very few such exceptions in the project, the most prominent being updated JAXP/JAXB/JAX-WS and integration of the enhanced JMX agent from JRockit. Our project management does not expect the exceptions to have any negative impact on the release plan. The project may still be delayed if the Expert Groups for the JSRs included in Java SE 7 (203, 292, 334, 336) decide to introduce changes which cannot be accomodated within the existing schedule. Apart from that caveat, Oracle remains confident with the published plan.

• Thread safe GUI programming

  - by James

  I have been programming Java with swing for a couple of years now, and always accepted that GUI interactions had to happen on the Event Dispatch Thread. I recently started to use GTK+ for C applications and was unsurprised to find that GUI interactions had to be called on gtk_main. Similarly, I looked at SWT to see in what ways it was different to Swing and to see if it was worth using, and again found the UI thread idea, and I am sure that these 3 are not the only toolkits to use this model. I was wondering if there is a reason for this design i.e. what is the reason for keeping UI modifications isolated to a single thread. I can see why some modifications may cause issues (like modifying a list while it is being drawn), but I do not see why these concerns pass on to the user of the API. Is there a limit imposed by an operating system? Is there a good reason these concerns are not 'hidden' (i.e. some form of synchronization that is invisible to the user)? Is there any (even purely conceptual) way of creating a thread safe graphics library, or is such a thing actually impossible? I found this http://blogs.operationaldynamics.com/andrew/software/gnome-desktop/gtk-thread-awareness which seems to describe GTK differently to how I understood it (although my understanding was the same as many people's) How does this differ to other toolkits? Is it possible to implement this in Swing (as the EDT model does not actually prevent access from other threads, it just often leads to Exceptions)

• CPU load, USB connection vs. NIC

  - by T.J. Crowder

  In general, and understanding the answer may vary by manufacturer and model (and driver, and...), in consumer-grade workstations with integrated NICs, does the NIC rely on the CPU for a lot of help (as is typically the case with a USB controller, for instance), or is it fairly intelligent and capable on its own (like, say, the typical Firewire controller)? Or is the question too general to answer? (If it matters, you can assume Linux.) Background: I'm looking at connecting a device (digital television capture) that will be delivering ~20-50 Mbit/sec of data to a somewhat under-powered workstation. I can get a USB 2 High-speed device, or a network-attached device, and am interested in avoiding impacting the CPU where possible. Obviously, if it's a 100Mbit NIC, that's roughly half its theoretical inbound bandwidth, whereas it's only roughly a tenth of the 480 Mbit/second the USB 2 "High Speed" interface. But if the latter requires a lot of CPU support and the former doesn't...

• Suppress log messages about 3ware disk temperature changes on CentOS?

  - by Stefan Lasiewski

  I have a number of CentOS 5 servers which use 3ware RAID controllers. These servers are bugging my team with messages about minor temperature changes, like this: Jun 8 12:32:39 HOST smartd[1231]: Device: /dev/twa0 [3ware_disk_01], SMART Usage Attribute: 194 Temperature_Celsius changed from 119 to 118 Jun 8 12:32:39 HOST smartd[1231]: Device: /dev/twa0 [3ware_disk_03], SMART Usage Attribute: 194 Temperature_Celsius changed from 122 to 121 How can I suppress these messages? According to man smartd.conf : To disable any of the 3 reports, set the corresponding limit to 0. Trailing zero arguments may be omitted. By default, all temperature reports are disabled (´-W 0´). On my systems, smartd is reporting about temperature changes by default. I tried a manual approach. In /etc/smartd.conf, I have the following: /dev/twa0 -d 3ware,1 -a -W 0 /dev/twa0 -d 3ware,3 -a -W 0 But this still does not suppress the messages. Since these messages show up in /var/log/messages, LogWatch is sending unnecessary emails every night.

• Session serialization in JavaEE environment

  - by Ionut

  Please consider the following scenario: We are working on a JavaEE project for which the scalability starts to become an issue. Up until now, we were able to scale up but this is no longer an option. Therefore we need to consider scaling out and preparing the App for a clustered environment. Our main concern right now is serializing the user sessions. Sadly, we did not consider from the beginning the issue and we are encountering the following excetion: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: org.apache.catalina.session.StandardSessionFacade I did some research and this exception is thrown because there are objects stored on the session which does not implement the Serializable interface. Considering that all over the app there are quite a few custom objects which are stored on the session without implementing this interface, it would require a lot of tedious work and dedication to fix all these classes declaration. We will fix all this declarations but the main concern is that, in the future, there may be a developer which will add a non Serializable object on the session and break the session serialization & replication over multiple nodes. As a quick overview of the project, we are developing using a home grown framework based on Struts 1 with the Servlet 3.0 API. This means that at this point, we are using the standard session.getAttribute() and session.setAttribute() to work with the session and the session handling is scattered all over the code base. Besides updating the classes of the objects stored on session and making sure that they implement the Serializable interface, what other measures of precaution should we take in order to ensure a reliable Session replication capability on the Application layer? I know it is a little bit late to consider this but what would be the best practice in this case? Furthermore, are there any other issues we should consider regarding this transition? Thank you in advance!

• Nagios Woudn't Start, now won't Stop!

  - by Bart B

  I ran an update on a CentOS server running Nagios, after the update, Nagios failed to start. The error in the logs was: Failed to obtain lock on file /var/run/nagios.pid: Permission denied So, I checked and there was no pid file for Nagios in /var/run. I created one and gave it the following permissions: -rwxr--r-- 1 nagios nagios 6 May 31 11:58 nagios.pid Nagios then started and seems to be running normally. The only problem is, it refuses to stop now, so I can't re-start it to add new servers and services to be monitored! When I issue the command "service nagios stop", I get [FAILED], but nothing at all gets outputted to the log, and the service remains up. Any ideas on how I can get the service to stop now? I'm running the RPM version which was installed via yum from the RPMForge repositories. The server is CenotOS 5.5.

• Prevent udev / uevents looking up DVD at boot time

  - by Sampo

  Problem: Boot time delay caused by udev. Early after initscripts starts there is message saying waiting for uevents to be processed and causing delay on boot, it seems that udev is looking if there is disc in dvd tray. After udev has found disc, boot process continues normally. Main question: How to prevent udev dvd lookup at boot time? Maybe there is some way to skip some udev related stuff and let boot process continue and then later instruct udev to do stuff that may cause some delay (delay in uevents, but not in main boot process, is acceptable after udev is initially loaded).

• Resizing partition using Gparted gives "can't have overlapping partitions" error

  - by Marcus

  I just decided to install Ubuntu 12.04 alongside Windows 7 on my Dell laptop. However I didn't do this manually but instead used the "Run Ubuntu alongside Windows 7" option upon installation, and now the partition that Ubuntu runs on has very little space (It's giving me warnings). I'm trying to use Gparted 0.12.1-5 (via a live CD) to give Windows less space and give Ubuntu more. I've managed to remove 100GB from the Windows partition so I now have some unallocated space between Windows and Ubuntu. This is what it looks like inside Ubuntu (not using the live CD, since it won't let me mount a USB to save a screenshot): http://i.stack.imgur.com/0keQq.png So first I take sda4 (extended?) and resize it to the left so it takes up all the unallocated space. Then I resize sda5 (ext4) as well so it takes up all the new space. However, when I hit apply, it fails on the first action (resizing sd4), saying "can't have overlapping partitions". Any ideas as to why this happens? I also tried resizing sda4 by just a few MB so that it definitely didn't overlap anything, but I still got the same error message. To clarify, I am doing it using the CD, I just took the screenshot from Ubuntu. Any help would be greatly appreciated! And again, I can't mount any USB (I'm following the guide on the gparted website but it says "Invalid argument" or something like that) so I couldn't attach the details file from Gparted. If this is needed, I may need some hints on how to solve the USB issue as well. :) Thanks

• Windows 7 pricing

  - by bwerks

  I'm having trouble wading through Microsoft's marketing information. Does anyone know if Windows 7 x86 to Windows 7 x64 is a valid upgrade path? I know you can't actually use the built-in "upgrade" installation path; this is more of a licensing question. Although that may have answered my own question: is this idea even possible? Or do "upgrade" versions of Windows function only when executed from inside the OS, and not when doing fresh installs? Thanks!

Proposed new MBR partition table: # A Start LBA End LBA Type 1 1 33 ee EFI Protective 2 34 1987 da Non-FS data 3 1988 1029662719 83 Linux 4 * 1029662720 2108995583 07 NTFS/HPFS May I update the MBR as printed above? [y/N] Clearly the MBR table is damaged or mismatched. But it does not reflect the correct GPT table partitions at all. How do I get the MBR repaired to match the GPT table (up to the 4 part limit of course)? The question is simply - Do I blindly say Yes to gptsync's suggestion? It looks sort of ok but not exactly so...Advice please on interpreting the above output to get my disk usable would be greatly appreciated. Thank You!

• Is what someone publishes on the Internet fair game when considering them for employment as a programmer?

  - by Jon Hopkins

  (Originally posted on Stack Overflow but closed there and more relevant for here) So we first interviewed a guy for a technical role and he was pretty good. Before the second interview we googled him and found his MySpace page which could, to put it mildly, be regarded as inappropriate. Just to be clear there was no doubt that it was his page (name, photos, matching biographical information and so on). The content was entirely personal and in no way related to his professional abilities or attitude. Is it fair to consider this when thinking about whether to offer them a job? In most situations my response would be what goes on in someone's private life is their own doing. However for anyone technical who professes (implicitly or explicitly) to understand the Internet and the possibilities it offers, is posting things in a way which can so obviously be discovered a significant error of judgement? EDIT: Clarification - essentially it was a fairly graphic commentary on porn (but of, shall we say, a non-academic nature). I'm actually more interested in the general concept than the specific incident as it's something we're likely to see more in the future as people put more and more of themselves on-line. My concerns are not primarily about him and how he feels about such things (he's white, straight, male and about the last possible victim of discrimination on the planet in that sense), more how it reflects on the company that a very simple search (basically his name) returns these things and that clients may also do it. We work in a relatively conservative industry.
