  • Big label generator

    - by jamiet
    Sometimes I write blog posts mainly so that I can find stuff when I need it later. This is such a blog post. Of late I have been writing lots of deployment scripts and I am fan of putting big labels into deployment scripts (which, these days, reside in SSDT) so one can easily see what’s going on as they execute. Here’s such an example from my current project: which results in this being displayed when the script is run: In case you care….PM_EDW is the name of one of our databases. I’m almost embarrassed to admit that I spent about half an hour crafting that and a few others for my current project because a colleague has just alerted me to a website that would have done it for me, and given me lots of options for how to present it too: http://www.patorjk.com/software/taag/#p=testall&f=Banner3&t=PM__EDW Very useful indeed. Nice one! And yes, I’m sure there are a myriad of sites that do the same thing - I’m a latecomer, ok? @Jamiet

  • Inheritance versus Composition in a business application

    - by ProfK
    I have a training management and tracking system, with a high level structure as follows: We have a Role1, e.g. Manager, Shift-boss, miner, etc. and a Candidate, training for that Role. The role has a list of courses and their subjects the candidate needs to complete to qualify for the role. Candidate has a TrainingHistory attribute, containing the courses and subjects they have completed, their results, and the date completed. Now I see it as a TrainingHistoryCourse is-a Course, extended to add DateCompleted etc. but something is nagging at me to rather use something like a TrainingHistoryRecord that has-a Course. How can I further analyse this to determine which pattern to use? Then, a Role has a list of RoleTask definitions that the Candidate must be observed practising, and a Candidate has a history of RoleTaskObservation objects recording their performance at these tasks. This is very similar to the course/subject requirement and history pattern for the candidate, except for one less hierarchical level, but, a RoleTaskObservation clearly does not have an is-a relationship with RoleTask, unless I block my nose and rather use ObservedRoleTask. I would prefer to use the same pattern for both subject/course and task/observation structures, but I think that would force me to adopt a composition pattern for TrainingHistoryCourse. What is the wisdom here? Always inherit where possible and validated by a solid is-a association, or always favour composition wherever possible? 1 Client specified this to be called JobTitle, but he isn't writing the app, and a JobTitle is only one attribute of a Role. Authorization roles are handled by the DevExpress framework and its customization hooks, so there would be very little little confusion between a business Role in my domain objects and an authorization role in lower level, framework code.

  • Increase application performance on Amazon AWS

    - by Honus Wagner
    I've got a client with an MVC v1 (.NET) application running on a micro instance. On this instance, I've got .NET, IIS 7.5, and MS SQL Server 2008 running to handle the application. The client has reported that it is taking nearly 10 seconds to process each request. Even loading the initial login page takes about that long, then logging in takes that long, etc etc. The currently running instance specs are as follows: 615 MB RAM Intel Xenon CPU E5430 @ 2.66GHz 2.78 GHz 64-Bit Is the memory availability the issue? or is it the processing power? I forsee two options: Change to a larget instance Set up a 2-tier architecture with two micro instances Which of these will give the application better performance? Thanks in advance.

  • Ubuntu 13.10 AdobeAIR application: Failed to load module "unity-gtk-module"

    - by nobuzz
    I have installed AdobeAIR on 13.10, but am getting the following error messages when using: Gtk-Message: Failed to load module "overlay-scrollbar" Gtk-Message: Failed to load module "unity-gtk-module" Has someone faced this issue. I looked at comment giving a possible resolution here , but that didn't help, as I already have those packages installed. Basically to install AdobeAIR, being a 32-bit, I had to install various i386 packages: libgtk2.0-0:i386 libnss3-1d:i386 libnspr4-0d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386 When I run the program as root, it opens up properly without errors. But that is not an option. Could it be a problem that necessary modules are not getting loaded on non-root user's environment.

  • insert null character using tamper data

    - by Jeremy Comulu
    Using the firefox extension tamper data (for modifing http requests that firefox makes) how do I insert a null character into a post field? I can enter normal characters, but binary characters in it are not urlencoded and are shown as is, so how do I enter the null character into a field? If you know of a firefox extension like tamper data that I can do this or a way to do this using tamper data please post.

  • How to Delete Your Metro Application’s Usage History in Windows 8

    - by Taylor Gibb
    Windows 8 includes an all new Task Manager, which brings a whole bunch of new features. One of my favorites is the App history tab, which allows geeks like us to monitor our applications resource usage. Sometimes you may wish to reset the counters though, so here’s how.

  • Python script won't write data when ran from cron

    - by Ruud
    When I run a python script in a terminal it runs as expected; downloads file and saves it in the desired spot. sudo python script.py I've added the python script to the root crontab, but then it runs as it is supposed to except it does not write the file. $ sudo crontab -l > * * * * * python /home/test/script.py >> /var/log/test.log 2>&1 Below is a simplified script that still has the problem: #!/usr/bin/python scheduleUrl = 'http://test.com/schedule.xml' schedule = '/var/test/schedule.xml' # Download url and save as filename def wget(url, filename): import urllib2 try: response = urllib2.urlopen(url) except Exception: import traceback logging.exception('generic exception: ' + traceback.format_exc()) else: print('writing:'+filename+';') output = open(filename,'wb') output.write(response.read()) output.close() # Download the schedule wget(scheduleUrl, schedule) I do get the message "writing:name of file;" inside the log, to which the cron entry outputs. But the actual file is nowhere to be found... The dir /var/test is chmodded to 777 and using whatever user, I am allowed to add and change files as I please.

  • btrfs: can i create a btrfs file system with data as jbod and metadata mirrored

    - by Yogi
    I am trying to build a home server that will be my NAS/Media server as well a the XBMC front end. I am planning on using Ubuntu with btrfs for the NAS part of it. The current setup consists of 1TB hdd for the OS etc and two 2TB hdd's for data. I plan to have the 2TB hdd's used as JBOD btrfs system in which i can add hdd's as needed later, basically growing the filesystem online. They way I had setup the file system for testing was while installing the OS just have one of the HDD's connected and have btrfs on it mounted as /data. Later on add another hdd to this file system. When the second disk was added btrfs made as RAID 0, with metadata being RAID 1. However, this presents a problem: even if one of the disk fails I loose all my data (mostly media). Also most of the time the server will be running without doing any disk access, i.e. the HDD's can be spun down, when a access request comes in this with the current RAID 0 setup both disks will spin up. in case I manage a JBOD only the disk that has the file needs to be spun up. This should hopefully reduce the MTBF for each disk. So, is there a way in which I can have btrfs setup such that metadata is mirrored but data stays in a JBOD formation? Another question I have is this, I understand that a full drive failure in JBOD will lose data on the drive, but having metadeta mirrored across all drives, will this help the filesytem correct errors that migh creep in (ex bit rot?) and is btrfs capable of doing this.

  • Android Photosphere Viewer Application

    - by Frisbetarian
    I'm aiming to develop an android app that simply views photosphere files. It should utilize the compass to pan around the sphere when the user moves his/her phone. I'm not aiming to create photospheres via the phone's camera with it, just upload the necessary jpegs and view them. Could anyone offer any advice as to how I could go about with implementing an API that views and gives the option to manipulate photosphere files?

  • Creating cookieless application on development machine with asp.net

    - by zaladane
    I am thinking about setting up a new domain to host static content on my website and have it cookieless just like Stackoverflow with their static domain. So before going ahead and buying the domain and setting it up I wanted to test it on my developement machine first under localhost (I have to mention that i am planning on having IIS running on my new domain for the static files). I therefore created a new application under IIS and disabled session state and forms authentication. When my main application needs resources like css, images and js , I use the path to the "static" application where they are hosted. The problem is that when I look at the request and the response for the requested files, they still have the session_id cookie defined as well as the asp.net authentication cookie. Is it at all possible to accomplish what i am trying to do on a development machine or do i have to just go ahead and purchase the new domain which hopefully with make things right? I tried to read about cookieless domain but can't figure out what i might be missing.

  • Temporarily share/deploy a python (flask) application

    - by Jeff
    Goal Temporarily (1 month?) deploy/share a python (flask) web app without expensive/complex hosting. More info I've developed a basic mobile web app for the non-profit I work for. It's written in python and uses flask as its framework. I'd like to share this with other employees and beta testers (<25 people). Ideally, I could get some sort of simple hosting space/service and push regular updates to it while we test and iterate on this app. Think something along the lines of dropbox, which of course would not work for this purpose. We do have a website, and hosting services for it, but I'm concerned about using this resource as our website is mission critical and this app is very much pre-alpha at this point. Options I've researched / considered Self host from local machine/network (slow, unreliable) Purchase hosting space (with limited non-profit resources, I'm concerned this is overkill) Using our current web server / hosting (not appropriate for testing) Thanks very much for your time!

  • Matrix Pattern Recognition Algorithm

    - by Andres
    I am designing a logic analyzer and I would like to implement some Matrix Algorithm. I have several channels each one represented by a row in the matrix and every element in the column would be the state, for example: Channel 1 1 0 0 1 0 1 1 0 1 Channel 2 1 1 0 1 1 0 0 1 1 Channel 3 0 1 0 1 1 0 1 0 0 Channel 4 0 0 1 0 0 1 0 0 1 I would like to detect a pattern inside my matrix for example, detect if exist and where the sub-matrix or pattern: 1 0 1 1 I think it can be accomplished testing element by element but I think there should be a better way of doing it. Is there any Java API or any way to do it ? If there is a API ARM optimized for NEON instructions would be great also but not mandatory. Thank you very much in advance.

  • Restore data from overwritten LVM

    - by Matthias Bayer
    I lost all of my data (8 TB) which I collected over the past few years yesterday because I made some seriuos mistakes during the remounting of my LVM. I run a XenServer5.6 installation with additional 4 harddisks for data storage. An LVM over those 4 HDDs was used to store all of my data. Yesterday, I reinstalled XenServer and wanted to mount my old Harddrives and add the LVM. I run xe sr-create [...] for all disks (/dev/sdb .. /dev/sde), but that was totally wrong. This command deletes the old LVM on the disks and created an new, empty lvm on every single disk with no partitions. No i got 4 empty harddrives :( Is it possible to recover some data from that lost LVM volumes? I have no clue how to do it because i deleted all informations about the old LVM. Is there a way to access the files insed that old lvm directly?

  • Improving performance of fuzzy string matching against a dictionary [closed]

    - by Nathan Harmston
    Hi, So I'm currently working for with using SecondString for fuzzy string matching, where I have a large dictionary to compare to (with each entry in the dictionary has an associated non-unique identifier). I am currently using a hashMap to store this dictionary. When I want to do fuzzy string matching, I first check to see if the string is in the hashMap and then I iterate through all of the other potential keys, calculating the string similarity and storing the k,v pair/s with the highest similarity. Depending on which dictionary I am using this can take a long time ( 12330 - 1800035 entries ). Is there any way to speed this up or make it faster? I am currently writing a memoization function/table as a way of speeding this up, but can anyone else think of a better way to improve the speed of this? Maybe a different structure or something else I'm missing. Many thanks in advance, Nathan

  • Setup asp.net mvc application as subdomain website

    - by a_m0d
    I'm trying to setup a local application on a subdomain on our company server. There is already an installation of sharepoint running on http://companyweb/, but I would like my application to run on http://orders.companyweb/. I tried creating a new website, leaving the IP address the same as it is for http://companyweb, and just changing the host header value to orders.companyweb. However, no matter where I try to access the site from (different computers around the network, including the server itself), I keep getting 404 errors. I then tried setting up a simple index.html and serving that up as the highest priority; however, I still got 404 errors. This makes me think that I have actually setup the site itself wrong. What should I change to be able to access this application correctly on all the local computers?

  • What is the best strategy for transforming unicode strings into filenames?

    - by David Cowden
    I have a bunch (thousands) of resources in an RDF/XML file. I am writing a certain subset of the resources to files -- one file for each, and I'm using the resource's title property as the file name. However, the titles are every day article, website, and blog post titles, so they contain characters unsafe for a URI (the necessary step for constructing a valid file path). I know of the Jersey UriBuilder but I can't quite get it to work for my needs as I detailed in a different question on SO. Some possibilities I have considered are: Since each resource should also have an associated URL, I could try to use the name of the file on the server. The down side of this is sometimes people don't name their content logically and I think the title of an article better reflects the content that will be in each text file. Construct a white list of valid characters and parse the string myself defining substitutions for unsafe characters. The downside of this is the result could be just as unreadable as the former solution because presumably the content creators went through a similar process when placing the files on their server. Choose a more generic naming scheme, place the title in the text file along with the other attributes, and tell my boss to live with it. So my question here is, what methods work well for dealing with a scenario where you need to construct file names out of strings with potentially unsafe characters? Is there a solution that better fills out my constraints?

  • How to Recover HDD Formatted by "Create a Recovery Drive" Tool of Windows 8.1?

    - by ide
    I have 2 TB USB HDD which had these drives F: about 1 TB with 750 GB data H: about 120 GB with 60 GB data I: about 780 GB with 250 GB data (For TV: It was raw in Windows but visible in the Smart TV) I took 521 MB from last part of H to get new G drive. Then I run "Create a Recovery Drive" tool of Windows 8.1 and chose G drive. It said all data in the drive will be deleted. I thought it is just G drive but it deleted my whole HDD. It created 32 GB new F drive with writing 337 MB on it and rest of HDD is unallocated. I tried these programs to get my first 3 drives but non of them helped for getting 1st partition.
