  • Are python's cryptographic modules good enough?

    - by Aerovistae
    I mean, say you were writing professional grade software that would involve sensitive client information. (Take this in the context of me being an amateur programmer.) Would you use hlib and hmac? Are they good enough to secure data? Or would you write something fancier by hand? Edit: In context of those libraries containing more or less the best hashing algorithms in the world, I guess it's silly to ask if you'd "write something fancier." What I'm really asking here is whether it's enough on its own.

  • Wiki based requirements engineering tool

    - by Shanon
    Hi, I'm looking to to build a wiki based tool the helps/aides in the requirements engineering process. More specifically I am hoping to end up with a tool that helps inexperienced users easily create and design requirements documents on a wiki platform. I was wondering if there exist any wiki/wiki platforms that either already exist or are easily extendible or would be worth looking at that for this purpose. For instance some of the features I was hoping to add would be to add structure to a document so that information is filled out in a standardised manner. Another idea I was looking at was to somehow create relationships between different types of documents (for example- a goal diagram gets evolves/ helps in the development of the class diagram). So far I have come across FOSwiki which claims to to fully customisalble...but I'm not sure what it means and what I can really do with that. Any input on FOSwiki is also highly appreciated.

  • Ubuntu 12.04 LTS 64 bit. Logitech m510 mouse not working!

  • How to derive euler angles from matrix or quaternion?

    - by KlashnikovKid
    Currently working on steering behavior for my AI and just hit a little mathematical bump. I'm in the process of writing an align function, which basically tries to match the agent's orientation with a target orientation. I've got a good source material for implementing this behavior but it uses euler angles to calculate the rotational delta, acceleration, and so on. This is nice, however I store orientation as a quaternion and the math library I'm using doesn't provide any functionality for deriving the euler angles. But if it helps I also have rotational matrices at my disposal too. What would be the best way to decompose the quaternion or rotational matrix to get the euler information? I found one source for decomposing the matrix, but I'm not quite getting the correct results. I'm thinking it may be a difference of column/row ordering of my matrices but then again, math isn't my strong point. http://nghiaho.com/?page_id=846

  • Removing AppPrincipals from Office365

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information So here is an annoying issue. If I have your AppPrincipal and secret, I can party as you! But as we go through our usual dev cycles, we create these ApplicationIDs. Hell Visual Studio will create them for us, to make things easy!The problem is, many a developer, and some a ITOgre, may leave these AppPrincipalIds sitting there and not clean them up when they are done playing. You can look for currently registered App Principals at https://yourtenant/_layouts/15/appprincipals.aspx The problem is, that URL shows you App Principals registered AND currently in use. Currently NOT in use App Principals are NOT shown on that page. The same issue applies on premises also, even though here I am talking specifically about Office 365. Getting rid of these in On-Prem is easy, just use the Object model (server side). Read full article ....

  • Uniquely identify a mobile device

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information Sometimes you need to identify every device your app is installed on uniquely. This is for instance important where you have per-device licensing restrictions. For Win8 store apps, You can use ASHWID (Application Specific Hardware Identifier). ASHWID will be different app to app and device to device. Any hardware changes to the device will cause the unique id to change. You can also detect minor change vs. major change to build custom level of tolerance in what is considered a change. For instance, ejecting a USB stick is a minor change. The below code snippet shows you how to get the unique device id, Read full article ....

  • Displaying thumbnails in google search results for flash games?

    - by serg
    Some sites are somehow displaying video preview thumbnails for pages that contain flash games in google search results. For example search for: site:www.thorgaming.com game I see this only on small sites which makes me believe google is not very happy about it. How do they do it and is it ok with google? I assume they are submitting thumbnails through video sitemaps, but I can't find any information about using them with flash games. I also run a few such sites through rich snipped testing tool and it didn't detect any microdata tags on a page.

  • How come I can not install plugins on my local Wordpress install?

    - by classer
    Hello, I got WordPress up and running fine on Ubuntu 10.04 by using this source except that when I try to update and install themes/plugins I get this following error message in wp-admin page: Installing Plugin: WordPress.com Stats 1.8.1 Downloading install package from http://downloads.wordpress.org/plugin/stats.1.8.1.zip… Unpacking the package… Could not create directory. /var/www/wordpress/wp-content/upgrade/stats.tmp/stats Actions: Return to Plugin Installer At first I thought I had to setup an FTP account but searched more and I found some information that says that I need to change the permissions of the wp-content folder which is located in the directory: /var/www/wordpress/wp-content I tried changing it by doing: sudo chmod -R 777 wp-content/ but when I tried installing a plugin I got the same error message. I also tried passing it 755 as a permission but still got the same thing. I settled on 755 because it is more secure I have read. How can I solve this problem safely and securely?

  • Possible automated Bing Ads fraud?

    - by Gary Joynes
    I run a website that generates life insurance leads. The site is very simple a) there is a form for capturing the user's details, life insurance requirements etc b) A quote comparison feature We drive traffic to our site using conventional Google Adwords and Bing Ads campaigns. Since the 6th January we have received 30-40 dodgy leads which have the following in common: All created between 2 and 8 AM Phone number always in the format "123 1234 1234' Name, Date Of Birth, Policy details, Address all seem valid and are unique across the leads Email addresses from "disposable" email accounts including dodgit.com, mailinator.com, trashymail.com, pookmail.com Some leads come from the customer form, some via the quote comparison feature All come from different IP addresses We get the keyword information passed through from the URLs All look to be coming from Bing Ads All come from Internet Explorer v7 and v8 The consistency of the data and the random IP addresses seem to suggest an automated approach but I'm not sure of the intent. We can handle identifying these leads within our database but is there anyway of stopping this at the Ad level i.e. before the click through.

  • Android application Database Framework

    - by Marek Sebera
    When creating mobile (specially Android) application, I usually come to touch with similar pattern of working with data. Usually I need to fetch some remote data (covered by authorization process) to local cache. And on next request: Check networking Check presence of cache file Check version of cache file (if networking) Get new version and save cache (if networking and file not in cache, or outdated) Data store is no-SQL JSON Document-Based (and yes, I know about CouchDB Android version, but it doesn't fit my needs yet.) Process of authorizing to data source and code for check version of local cache is adapted to application. But the other code (handling network, saving cache, handling exceptions,...) is always the same. Is there any Data Store helper I can use, which provides functions I described above?

  • Random MongoDb Syntax: Updates

    - by Liam McLennan
    I have a MongoDb collection called tweets. Each document has a property system_classification. If the value of system_classification is ‘+’ I want to change it to ‘positive’. For a regular relational database the query would be: update tweets set system_classification = 'positive' where system_classification = '+' the MongoDb equivalent is: db.tweets.update({system_classification: '+'}, {$set: {system_classification:'positive'}}, false, true) Parameter Description { system_classification: '+' } the first parameter identifies the documents to select { $set: { system_classification: 'positive' } } the second parameter is an operation ($set) and the parameter to that operation {system_classification: ‘positive’} false the third parameter indicates if this is a regular update or an upsert (true for upsert) true the final parameter indicates if the operation should be applied to all selected documents (or just the first)

  • webmaster tools 500 crawl error for asp faceted navigation that does not exist

    - by user19007
    i am getting 2,500 type 500 url errors in google webmaster tools. These pages are faceted navigation results that can not be reached by a site visitor. These pages do not exist. We are using faceted navigation with the Volusion platform (asp.net, I think). I have specified url parameters in webmaster tools so that google will not try to index anything faceted. This does not stop the errors from generating. I am concerned about how this might effect seo (bleeding page rank). I can provide additional information if needed. I am not sure how to solve this. I have started down the path of creating 301's, but having some difficulty there as well.

  • How to control fan speed and temperatures on Asus A8Js laptop running Ubuntu Server?

    - by Azeworai
    Hi, I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?

  • Is there animation software available for Ubuntu?

    - by Robert Low
    Is there commercial-grade computer animation software available for Ubuntu, similar to the professional software sold for the Windows operating system? This question goes out to those of you who may be using such software professionally. My daughter recently graduated from the Art Institute of Seattle, and needs to put together an animation portfolio in order to interest employers in the field. As you know, such software is usually provided by the employer and the costs are high - several thousand dollars. I suggested that she investigate Ubuntu as a possible way to acquire the tools she needs. But, since I have no idea what might be available, either as open source or proprietary animation software, I am reaching out to the Ubuntu community for help in the hope someone who is using such software can help her. Thank you for reading this post, and for any information you might have.

  • RESTful API design - should a PUT return related data?

    - by alexmcroberts
    I have an API which allows a user to update their system status; and a separate call to retrieve system status updates from other users. Would it make sense to unify them under a PUT request where a user would request a PUT update with their own status update, and they would receive the status updates of other users? My solution would allow the PUT request to call the GET request method internally. The reason behind this is that when a user updates their system status they should be informed of other users status immediately, and I don't feel that having 2 seperate requests is necessary - and should be optional. I intend to keep the GET request for other users status as a status update for a user is not necessarily required in order to retrieve other users status', but once they update their own status is it vital that they get information about other users.

  • Unity and games don't work on new Thinkpad T420

    - by Clay Smalley
    Here's my setup: Lenovo ThinkPad T420, brand new NVIDIA Graphics Card 4GB of Ram 128GB Solid State Drive Intel Core i5 Processor Given these specs, there's no reason games and Unity shouldn't be working. The strange thing is that both do work when I run from a live USB, but not when Ubuntu is installed to the hard drive. Is there something different with the 3D capabilities of running from the computer as opposed to running from the live USB? Edit: Some more information: When I log in for the first time when running from the hard drive, Ubuntu says "It seems that you do not have the hardware required to run Unity. Please choose Ubuntu Classic at the login screen and you will be using the traditional environment."
