Any thoughts as to why this would happen?

  • Javascript with Django?

    - by Rosarch
    I know this has been asked before, but I'm having a hard time setting up JS on my Django web app, even though I'm reading the documentation. I'm running the Django dev server. My file structure looks like this: mysite/ __init__.py MySiteDB manage.py settings.py urls.py myapp/ __init__.py admin.py models.py test.py views.py templates/ index.html Where do I want to put the Javascript and CSS? I've tried it in a bunch of places, including myapp/, templates/ and mysite/, but none seem to work. From index.html: <head> <title>Degree Planner</title> <script type="text/javascript" src="/scripts/JQuery.js"></script> <script type="text/javascript" src="/media/scripts/sprintf.js"></script> <script type="text/javascript" src="/media/scripts/clientside.js"></script> </head> From urls.py: (r'^admin/', include(admin.site.urls)), (r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': 'media'}) (r'^.*', 'mysite.myapp.views.index'), I suspect that the serve() line is the cause of errors like: TypeError at /admin/auth/ 'tuple' object is not callable Just to round off the rampant flailing, I changed these settings in settings.py: MEDIA_ROOT = '/media/' MEDIA_URL = 'http://127.0.0.1:8000/media'

  • Rebuilding old (2010) django project in 2012

    - by birgit
    I am trying to make an old Django project run again. After seemingly having solved issues with old sorl.thumbnail versions and deprecated expressions I now get this error when running python manage.py runserver I also tried to copy & paste my old files into a new Django project and get the exactly same error.

  • How to manage a home-grown YUM package repo?

    - by TomOnTime
    There are plenty of websites that explain how to manage a mirror of YUM repos. I want to run a repo for my home-grown packages. Is there a good way to manage such repos? What I need to do: Manage 3 repos: unstable, testing, stable Self-service functions that let users add/remove/promote packages (promote means moving a package unstable?testing or testing-stable). ACLs that control which users/groups may add/remove/promote packages. Automatically re-sign packages as they move repo to repo (since the GPG key for "stable" should be different than "unstable") Automatically run "createrepo" to update repodata when needed. Suggestions?

  • How do I work around this problem creating a virtualenv environment with a custom-build Python?

    - by Daryl Spitzer
    I need to run some code on a Linux machine with Python 2.3.4 pre-installed. I'm not on the sudoers list for that machine, so I built Python 2.6.4 into (a subdirectory in) my home directory.

  • ObjectListView: Custom Sorter

    - by Mike
    In the control ObjectListView(http://objectlistview.sourceforge.net/html/cookbook.htm), I'm trying to add a custom sorter where it ignores "The" and "A" prefixes. I managed to do it with a regular ListView, but now that I switched to ObjectListView(a lot more features, and ease), I can't seem to do the same. The following is the Main comparer in the ObjectListView code i think... public int Compare(object x, object y) { return this.Compare((OLVListItem)x, (OLVListItem)y); } Original Sorter for ascending, as an example (Ignoring "A" and "The") public class CustomSortAsc : IComparer { int IComparer.Compare(Object x, Object y) { string[] px = Convert.ToString(x).Split(' '); string[] py = Convert.ToString(y).Split(' '); string newX = ""; string newY = ""; for (int i = 0; i < px.Length; i++) { px[i] = px[i].Replace("{", ""); px[i] = px[i].Replace("}", ""); } for (int i = 0; i < py.Length; i++) { py[i] = py[i].Replace("{", ""); py[i] = py[i].Replace("}", ""); } if ((px[1].ToLower() == "a") || (px[1].ToLower() == "the")) { if (px.Length > 1) { for (int i = 2; i < px.Length; i++) newX += px[i]; } } else { for (int i = 1; i < px.Length; i++) newX += px[i]; } if ((py[1].ToLower() == "a") || (py[1].ToLower() == "the")) { if (py.Length > 1) { for (int i = 2; i < py.Length; i++) newY += py[i]; } } else { for (int i = 1; i < py.Length; i++) newY += py[i]; } return ((new CaseInsensitiveComparer()).Compare(newX, newY)); }

  • Python read multiline JSON

  • How do NTP Servers Manage to Stay so Accurate?

    - by Akemi Iwaya
    Many of us have had the occasional problem with our computers and other devices retaining accurate time settings, but a quick sync with an NTP server makes all well again. But if our own devices can lose accuracy, how do NTP servers manage to stay so accurate? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Photo courtesy of LEOL30 (Flickr). The Question SuperUser reader Frank Thornton wants to know how NTP servers are able to remain so accurate: I have noticed that on my servers and other machines, the clocks always drift so that they have to sync up to remain accurate. How do the NTP server clocks keep from drifting and always remain so accurate? How do the NTP servers manage to remain so accurate? The Answer SuperUser contributor Michael Kjorling has the answer for us: NTP servers rely on highly accurate clocks for precision timekeeping. A common time source for central NTP servers are atomic clocks, or GPS receivers (remember that GPS satellites have atomic clocks onboard). These clocks are defined as accurate since they provide a highly exact time reference. There is nothing magical about GPS or atomic clocks that make them tell you exactly what time it is. Because of how atomic clocks work, they are simply very good at, having once been told what time it is, keeping accurate time (since the second is defined in terms of atomic effects). In fact, it is worth noting that GPS time is distinct from the UTC that we are more used to seeing. These atomic clocks are in turn synchronized against International Atomic Time or TAI in order to not only accurately tell the passage of time, but also the time. Once you have an exact time on one system connected to a network like the Internet, it is a matter of protocol engineering enabling transfer of precise times between hosts over an unreliable network. In this regard a Stratum 2 (or farther from the actual time source) NTP server is no different from your desktop system syncing against a set of NTP servers. By the time you have a few accurate times (as obtained from NTP servers or elsewhere) and know the rate of advancement of your local clock (which is easy to determine), you can calculate your local clock’s drift rate relative to the “believed accurate” passage of time. Once locked in, this value can then be used to continuously adjust the local clock to make it report values very close to the accurate passage of time, even if the local real-time clock itself is highly inaccurate. As long as your local clock is not highly erratic, this should allow keeping accurate time for some time even if your upstream time source becomes unavailable for any reason. Some NTP client implementations (probably most ntpd daemon or system service implementations) do this, and others (like ntpd’s companion ntpdate which simply sets the clock once) do not. This is commonly referred to as a drift file because it persistently stores a measure of clock drift, but strictly speaking it does not have to be stored as a specific file on disk. In NTP, Stratum 0 is by definition an accurate time source. Stratum 1 is a system that uses a Stratum 0 time source as its time source (and is thus slightly less accurate than the Stratum 0 time source). Stratum 2 again is slightly less accurate than Stratum 1 because it is syncing its time against the Stratum 1 source and so on. In practice, this loss of accuracy is so small that it is completely negligible in all but the most extreme of cases. Have something to add to the explanation? Sound off in the comments.

  • dpkg stuck downloading font files

    - by Bob Bowles
    I have been reinstalling Ubuntu 12.04. The install from USB works fine, and I could update everything OK, but when I got to re-installing my application software I hit a snag. One of the packages I tried to re-install was ttf-mscorefonts-installer. dpkg stalled during this setup, downloading a font file (it had tried to download it all night). I stopped dpkg, and attempted to re-start downloading something else, but it would not let me. The commands I typed are as follows: bob@bobStudio:~$ sudo rm /var/lib/dpkg/lock This unlocks dpkg, but if I try to do something I get the following message (eg): bob@bobStudio:~$ sudo apt-get install synaptic E: dpgk was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem So, I did just that: bob@bobStudio:~$ sudo dpkg --configure -a whereupon it started the previously failed download all over again. I went round the loop here a few times and each time after the configure command it re-started the failing download, but then I got this: bob@bobStudio:~$ sudo dpkg --configure -a Setting up update-notifier-common (0.119ubuntu8.4) ... ttf-mscorefonts-installer: downloading http://downloads.sourceforge.net/corefonts/andale32.exe Traceback (most recent call last): File "/usr/lib/update-notifier/package-data-downloader", line 234, in process_download_requests dest_file = urllib.urlretrieve(files[i])[0] File "/usr/lib/python2.7/urllib.py", line 93, in urlretrieve return _urlopener.retrieve(url, filename, reporthook, data) File "/usr/lib/python2.7/urllib.py", line 239, in retrieve fp = self.open(url, data) File "/usr/lib/python2.7/urllib.py", line 207, in open return getattr(self, name)(url) File "/usr/lib/python2.7/urllib.py", line 344, in open_http h.endheaders(data) File "/usr/lib/python2.7/httplib.py", line 954, in endheaders self._send_output(message_body) File "/usr/lib/python2.7/httplib.py", line 814, in _send_output self.send(msg) File "/usr/lib/python2.7/httplib.py", line 776, in send self.connect() File "/usr/lib/python2.7/httplib.py", line 757, in connect self.timeout, self.source_address) File "/usr/lib/python2.7/socket.py", line 553, in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM): IOError: [Errno socket error] [Errno -2] Name or service not known Setting up ttf-mscorefonts-installer (3.4ubuntu3) ... bob@bobStudio:~$ sudo apt-get update E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/ bob@bobStudio:~$ sudo rm /var/lib/dpkg/lock bob@bobStudio:~$ sudo apt-get update E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/ The good news is that, once I sorted out the file locks, this seems to have permanently aborted the setup of the font package, so at least I can do something else with dpkg. That leaves two questions: 1) How could I have broken the loop without actually crashing out of dpkg? 2) How can I set up the ttf-mscorefonts-installer package in the future? Is this download really broken, or is it 'just' a bad Internet connection?

  • Evaluating Solutions to Manage Product Compliance? Don’t Wait Much Longer

    - by Evelyn Neumayr
    By Kerrie Foy, Director PLM Product Marketing, Oracle Depending on severity, product compliance issues can cause various problems from run-away budgets to business closures. But effective policies and safeguards can create a strong foundation for innovation, productivity, market penetration and competitive advantage. If you’ve been putting off a systematic approach to product compliance, it is time to reconsider that decision. Why now?  No matter what industry, companies face a litany of worldwide and regional regulations that require proof of product compliance and environmental friendliness for market access.  For example, Restriction of Hazardous Substances (RoHS), a regulation that restricts the use of six dangerous materials used in the manufacture of electronic and electrical equipment, was originally adopted by the European Union in 2003 for implementation in 2006 and has evolved over time through various regional versions for North America, China, Japan, Korea, Norway and Turkey. In addition, the RoHS directive allowed for material exemptions used in Medical Devices, but that exemption ends in 2014. Additional regulations worth watching are the Battery Directive, Waste Electrical and Electronic Equipment (WEEE), and Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) directives. Additional regulations are expected from organizations such as the Food and Drug Administration in the US and similar organizations elsewhere. Meeting compliance requirements and also successfully investing in eco-friendly designs can be a major challenge. It may involve transforming business models, go-to-market strategies, supply networks, quality assurance policies and compliance processes.  Without a single source of truth for product data and without proper processes in place, ensuring product compliance burgeons into a crushing task that is cost-prohibitive and overwhelming.  However, the risk to consumer goodwill and satisfaction, revenue, business continuity, and market potential is too great not to solve the compliance challenge. Companies are beginning to adapt and thrive by implementing systematic approaches to product compliance that are more than functional bandages, they are revenue-generating engines. Consider working with Oracle to help you address your compliance needs. Many of the world’s most innovative leaders and pioneers are leveraging Oracle’s Agile Product Lifecycle Management (PLM) portfolio of enterprise applications to manage the product value chain, centralize product data, automate processes, and launch more eco-friendly products to market faster.   Particularly, the Agile Product Governance & Compliance (PG&C) solution provides out-of-the-box functionality to integrate actionable regulatory information into the enterprise product record from the ideation to the disposal/recycling phase.  Agile PG&C is a comprehensive solution that makes product compliance per corporate initiatives and regulations more reliable and efficient. Throughout product lifecycles, use the solution to support full material disclosures, gain rapid visibility into non-compliance issues, efficiently manage declarations with your suppliers, feed compliance data into a corrective action if a product must be changed, and swiftly satisfy audits by showing all due diligence tracked in one solution. Given the compounding regulation and consumer focus on urgent environmental issues, now is the time to act. Implementing an enterprise-wide systematic approach to product compliance is a competitive investment. From the start, Agile PG&C enables companies to confidently design for compliance and sustainability, reduce the cost of compliance, minimize the risk of business interruption, deliver responsible products, and inspire new innovation.  Don’t wait any longer! To find out more about Agile Product Governance & Compliance download the data sheet, contact your sales representative, or call Oracle at 1-800-633-0738.

  • Should I manage authentication on my own if the alternative is very low in usability and I am already managing roles?

    - by rumtscho
    As a small in-house dev department, we only have experience with developing applications for our intranet. We use the existing Active Directory for user account management. It contains the accounts of all company employees and many (but not all) of the business partners we have a cooperation with. Now, the top management wants a technology exchange application, and I am the lead dev on the new project. Basically, it is a database containing our know-how, with a web frontend. Our employees, our cooperating business partners, and people who wish to become our cooperating business partners should have access to it and see what technologies we have, so they can trade for them with the department which owns them. The technologies are not patented, but very valuable to competitors, so the department bosses are paranoid about somebody unauthorized gaining access to their technology description. This constraint necessitates a nightmarishly complicated multi-dimensional RBAC-hybrid model. As the Active Directory doesn't even contain all the information needed to infer the roles I use, I will have to manage roles plus per-technology per-user granted access exceptions within my system. The current plan is to use Active Directory for authentication. This will result in a multi-hour registration process for our business partners where the database owner has to manually create logins in our Active Directory and send them credentials. If I manage the logins in my own system, we could improve the usability a lot, for example by letting people have an active (but unprivileged) account as soon as they register. It seems to me that, after I am having a users table in the DB anyway (and managing ugly details like storing historical user IDs so that recycled user IDs within the Active Directory don't unexpectedly get rights to view someone's technologies), the additional complexity from implementing authentication functionality will be minimal. Therefore, I am starting to lean towards doing my own user login management and forgetting the AD altogether. On the other hand, I see some reasons to stay with Active Directory. First, the conventional wisdom I have heard from experienced programmers is to not do your own user management if you can avoid it. Second, we have code I can reuse for connection to the active directory, while I would have to code the authentication if done in-system (and my boss has clearly stated that getting the project delivered on time has much higher priority than delivering a system with high usability). Third, I am not a very experienced developer (this is my first lead position) and have never done user management before, so I am afraid that I am overlooking some important reasons to use the AD, or that I am underestimating the amount of work left to do my own authentication. I would like to know if there are more reasons to go with the AD authentication mechanism. Specifically, if I want to do my own authentication, what would I have to implement besides a secure connection for the login screen (which I would need anyway even if I am only transporting the pw to the AD), lookup of a password hash and a mechanism for password recovery (which will probably include manual identity verification, so no need for complex mTAN-like solutions)? And, if you have experience with such security-critical systems, which one would you use and why?
