  • How to correctly create a virtual file system?

    - by Paul
    A task in my homework assignment asks me to create a virtual file system, mount it, and perform some operations on it. I am supposed to create a file of 10 MB whose bits are all set to 0, format it as ext3 and mount it. This is how I've done that: dd if=/dev/zero of=~/filesyst bs=10485760 count=1 sudo mkfs.ext3 ~/filesyst sudo mount –o loop ~/filesyst /media/fuse Even though I've used /dev/sero, the file i still full of gibberish characters (mostly at-signs). The permissions on /media/fuse are drw-rw-rw- (which are alright), but the permissions on the files inside it are something like this: d????????? ? ? ? ? ? lost+found -????????? ? ? ? ? ? secret_bin Where have I gone wrong?

  • 1 Zettabyte Is Equal to 1 Million Petabytes

    - by Gopinath
    Geeks recently coined a new English term, Zettabyte, to measure the rapidly growing digital information footprint. So what is a Zettabyte? A Zettabyte is equal to 1 million Petabytes or 1 trillion terabytes and 1 quadrillion gigabytes. Symbol To Represent Zettabyte According to wikipedia the symbol ZB is used to represent a Zettabyte. So we can write 10 ZB to represent 10 Zettabytes. Human’s Digital Output Will be 1.2 Zettabytes By End Of 2010 Are you wondering why do we need a term to measure digital data? Tech research firm IDC has recently published a report that estimates current digital footprint created by us so far at 8 million Petabytes – the equivalent of 8,000,000,000,000 GB. This foot print is expected to pass 1.2 Zettabytes by the end of 2010. cc image credit:flickr Join us on Facebook to read all our stories right inside your Facebook news feed.

  • Launching a URL from an OOB Silverlight Application

    So I'm working on this code browser mostly to help me with my fading memory. In the app I want to be able to launch a url. So I do my normal thing and put a line of code that looks like this:System.Windows.Browser.HtmlPage.Window.Navigate(new Uri(ThisURI), "_blank");I was agast when I realized that this didn't work, for that matter it didn't even blow... grr... but with a bit of research I found that the hyper link button worked so a ended up making a little class like this:public class MyHyperLink...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How do games make money? What models do they use?

    - by cable729
    I'm trying to research the ways in which games make money. I want to know more about the models they use (free/premium, trial/subscription, free-to-play with micro-transactions, etc.). In addition, I want information on which models work for which games, what models are best for which age groups, etc. I've tried my best to find information, and Google hasn't turned anything up at all. I think I'll stop by my University's library and see if there's anything there. This may seem like a broad question, but I'm looking for links and titles of books, not typed-out answers.

  • FFmpeg & Installation on phpmyadmin

    - by Vivek
    I am attempting to have an interface in which people can upload music files and listen to them through the site. The biggest problem obviously is that someone who uploads an audio track in mp3 format into Mozilla wouldn't be able to play it back (since MF doesn't support mp3 playback since I'm using jPlayer). I did some research and found out that I could use command line php using FFmpeg to convert the mp3 to ogg or some other supportable format. I believe I understand (a little bit) how command line php works but I was wondering how I could install it onto phpmyadmin on my hosting service? Could anyone link me to a tutorial or care to explain? I tried googling it but I just couldn't find it.

  • About to graduate from good school without any progamming skills

    - by newprint
    Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from a good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been taught how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

  • How can I resize an external USB NTFS partition?

    - by chris
    I have a new USB drive which came with a single NTFS partition. How can I shrink that so that I can create an ext4 partition? gparted does not seem to have the "Resize" option highlighted. Update: After following the directions below, after unmounting I am still not able to resize the partition. There is a warning though: "Unable to find mount point. Unable to read the contents of this file system! Because of this, some operations may be unavailable. The following list of software packages is required for ntfs file system support: ntfsprogs". However, with the partition mounted, I can read & write to the file system on the drive just fine, and ntfsprogs is installed and current. What's next?

  • CS, SE, HCI, Information Science, Please recommendation for further education of the former performing art manager seeking career in IT industries? [on hold]

    - by Baek Seungjoo
    IT specialists there J Thank you very much for your collective efforts here, and I got huge help reading your professional comments and advices on each questions I have searched so far! This time, I would like to ask for your practical advices or recommendation on what I am struggling on at this moment. I am currently seeking higher education for my career transition from performing art manager and director to “IT software and/or service development and management specialist”. However, as this field is quite new to me, and there are lots of different work positions, I have no idea which grad major I better pursue in order to get qualification. Of course I know this question could sounds wired as it is kind of personal choice. But my lack of understanding on how IT software companies work in general, your practical and experience-based advice will be great help to me, who spent more than two months of self-research on net. OK. Before my question, here is my plan and history, which are quite different from those currently in IT industry I think… 1) Target Firstly, get career transition into IT service or products companies and get experiences. Eventually, pursue IT entrepreneurship in combination with my arts and cultural production and business expertise. 2) Background Career: performing arts director and manager in theatre-based scale opera and musical Art education in youth BA in literature and Chinese studies (Art & Humanities) MA in Cultural & Creative Industries (Art & Humanities) – dissertation with focus on digital prosumption and the lived experience of the prosumer. (a qualitative research on the agents in the digital world) 2) Personally Huge interest in IT hardware and software, and their trend. Skills to build up, repair, tune PCs -of course this is no more than personal hobby, but shows my interests in this field. 4) Problem Encounter a question “So, what do you think you can contribute practically in this position”. This question turn me down everytime I go through job interviews, and I decided more education in the relevant area. Here are my questions. 1) In terms of work positions in IT software companies, I wonder if I can put the comparison of what “Artists” is to “Arts Manager or Director” is what “Developer” is to “Product Manager”. (Of course, this stereotypical division of Artist-Art Manager is out of sense because the domain overlaps to some extent, and is blurring at least in my field, and they are in different contexts, but just speaking easily.) Normally, artist comes with special arts educations, and they live in their own world of artistic inspiration and creation, and they feel alive in practice and on stages. Meanwhile, from the point of staging and managing productions, the role of art manager is critical as well. Our role cares how the production appeals to the audience in effective way, how to make profit and future sustainable management through that, how to set up future strategy in consideration of the external conditions such as political and social circumstances, audience trend and level, other production trends from on-going and historical perspectives, how and what the production make voice to the society from political, economic, humanitarian stances. So, we need keen eyes on economic, political, and societal environment, have to understand human-being and their desires, must know how to make presentation and attract investors, must have sense in managing and fighting over the limited financial resource, how to extend networking and so on. It is common that the two agents create productions in collaboration (normally not in that ideal way but in conflict and fight though J ). So, we need to know each other’s expertise to some extent, for better production. What are the work positions in IT software industries equivalent to the role of “art manager” in performing arts? From my view, considering developers come with special education in the world of computer science, software engineering, or others (self-education sometimes), and they express themselves with the arts of coding, computer languages on the black screen, and make sort of their artistic production online to the audience, I guess there might be someone who collaborate with developers in creating, managing, and launching IT services or products. 2) Which education among CS, SE, HCI, Information Science, is needed for those seeking such work position? Especially for person like me. (At this moment, Information Science has the highest possibility to get in, since I lack Calculus and Math in undergrad educaiton. But please let me know irrespective of this concern, I think there are ways to back it up if CS or SE education needed in my case) 3) Which field between Information Science and HCI can be more practical background regarding job hungting? And which of them have more demands in job market? AS I checked, HCI is more close to CS than IS in its focus of study area. Thank you very much for your patience reading such a long inquiry, and I appreciate to your efforts in advance. Have a nice day in this beautiful summer.

  • How do I communicate with an IronPython component in a C#/XNA game?

    - by Jonathan Hobbs
    My XNA game is component-oriented, and has various components for position, physics representation, rendering, etc, all of which extend a base Component class. The player and enemies also have controllers which are currently defined in C#. I'd like to turn them into Python scripts, but I'm not sure how to interact with those scripts. The examples in Embedding IronPython in a C# Application suggest I'd have to create a wrapper class (e.g. a Script component) which compiles a Python script, and call the Update methods of the component in the script Is this the most effective way of working with a Python object? I feel that I'm missing something in my research - there must be a way to load up a script, instantiate a Python object and then work directly with it from within C#. Or is the wrapper required?

  • Is acousting fingerprinting too broad for one audio file only?

    - by IBG
    So we were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acousting fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

  • Corsair Hydro i series cpu cooler fan control

    - by user214690
    Im relatively new at Ubuntu and have found an answer to basically every single issue ive ever had thru this site... Otherthan this. I have been toying with the idea of a Corsair h80i for my dual boot system (win7/U12.10) and mostly use it in ubuntu. I have done some research on the interweb regarding fan control in linux and nearly ran up short untill I came across this thread: http://ubuntuforums.org/archive/index.php/t-2096166.html And it seems to have worked around it. (altho I have not tested it for myself) Is there any program/library/source that can be used to control the fans without having to MacGuyver it??

  • Final Year Project Advice: what impact on my CV [closed]

    - by Devon Smith
    I am being offered - as a final year project - to do a Company Website. This is basically an out-house project and I am not completely sure whether I should take it. The requirements are : Company Information User Registration Order placements. The technologies that I should use are PHP, Javascript, HTML, CSS and maybe Java Servlets. This appears to me a very basic project and I need an opinion as to what effect it might have on my CV. Is it worth to do it? Or should I go into some research project or something that has not been done before?

  • Logging in JSON Effect on Performance

    - by Pius
    I see more and more articles about logging in JSON. You can also find one on NodeJS blog. Why does everyone like it so much? I can only see more operations getting involved: A couple new objects being created. Stringifying objects, which either involves calculating string length or multiple string allocations. GCing all the crap that was created. Is there any test on performance when using JSON logging and regular string logging? Do people use JSON (for logging) in enterprise projects?

  • Plug-in or framework recommendation for showing content preview fly-over in CMS

    - by Michael Huang
    The requirement is to have either front end plug-in or back end processor that generates the preview of contents (such as images, videos, PDF files, HTML pages) in a preview popup when user mouse hovers the content. I did some research on this, seems that there are assorted jquery plugins for each type of files, but what we are looking for is a framework that handles all types of file previews. Ideally, we want to generate preview images on the backend, considering the cost of retrieving content on front end. I did find some open source or proprietary CMS that provides this feature, but usually they are shipped as one suite and the API for file preview might not be open. Is there any java or jquery framework that handles file preview? Thanks a lot

  • Fast Track Data Warehouse 3.0 Reference Guide

    Microsoft just release Fast Track Data Warehouse 3.0 Reference Guide version. The new changes are increased memory recommendation and the disks per RAID group change from 2-disk RAID 1 to 4-Disk RAID 10. Memory The earlier FTDW reference architecture cited 4GB memory per core. There was no rational behind this, but it was felt some rule was better than no rule. The new FTDW RG correctly cites the rational that more memory helps keep hash join intermediate results and sort operations in memory. 4-Disk...(read more)

  • Why is 2^16 a "special" number?

It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

  • What is good side of PageRank?

    - by SharkTheDark
    I am doing research about backlinks/PR/SEO/Search Result position and all I read about is that PageRank is not important, that it worth before but now it's not important at all. Only thing I found useful about it that is "change Search Result position", but ONLY if there are two sites with same keywords and same text content value, then Search Engine will check which site has higher PR and place that site above lowest one. Google counts PR importance as 20% for displaying search rankings, and Yahoo! is like 3%... Correct me if I am wrong... Is there any other good thing from it?

  • Microsoft Sql Server 2008 R2 System Databases

    For a majority of software developers little time is spent understanding the inner workings of the database management systems (DBMS) they use to store data for their applications.  I personally place myself in this grouping. In my case, I have used various versions of Microsoft’s SQL Server (2000, 2005, and 2008 R2) and just recently learned how valuable they really are when I was preparing to deliver a lecture on "SQL Server 2008 R2, System Databases". Microsoft Sql Server 2008 R2 System DatabasesSo what are system databases in MS SQL Server, and why should I know them? Microsoft uses system databases to support the SQL Server DBMS, much like a developer uses config files or database tables to support an application. These system databases individually provide specific functionality that allows MS SQL Server to function. Name Database File Log File Master master.mdf mastlog.ldf Resource mssqlsystemresource.mdf mssqlsystemresource.ldf Model model.mdf modellog.ldf MSDB msdbdata.mdf msdblog.ldf Distribution distmdl.mdf distmdl.ldf TempDB tempdb.mdf templog.ldf Master DatabaseIf you have used MS SQL Server then you should recognize the Master database especially if you used the SQL Server Management Studio (SSMS) to connect to a user created database. MS SQL Server requires the Master database in order for DBMS to start due to the information that it stores. Examples of data stored in the Master database User Logins Linked Servers Configuration information Information on User Databases Resource DatabaseHonestly, until recently I never knew this database even existed until I started to research SQL Server system databases. The reason for this is due largely to the fact that the resource database is hidden to users. In fact, the database files are stored within the Binn folder instead of the standard MS SQL Server database folder path. This database contains all system objects that can be accessed by all other databases.  In short, this database contains all system views and store procedures that appear in all other user databases regarding system information. One of the many benefits to storing system views and store procedures in a single hidden database is the fact it improves upgrading a SQL Server database; not to mention that maintenance is decreased since only one code base has to be mainlined for all of the system views and procedures. Model DatabaseThe Model database as the name implies is the model for all new databases created by users. This allows for predefining default database objects for all new databases within a MS SQL Server instance. For example, if every database created by a user needs to have an “Audit” table when it is  created then defining the “Audit” table in the model will guarantees that the table will be located in every new database create after the model is altered. MSDB DatabaseThe MSDBdatabase is used by SQL Server Agent, SQL Server Database Mail, SQL Server Service Broker, along with SQL Server. The SQL Server Agent uses this database to store job configurations and SQL job schedules along with SQL Alerts, and Operators. In addition, this database also stores all SQL job parameters along with each job’s execution history.  Finally, this database is also used to store database backup and maintenance plans as well as details pertaining to SQL Log shipping if it is being used. Distribution DatabaseThe Distribution database is only used during replication and stores meta data and history information pertaining to the act of replication data. Furthermore, when transactional replication is used this database also stores information regarding each transaction. It is important to note that replication is not turned on by default in MS SQL Server and that the distribution database is hidden from SSMS. Tempdb DatabaseThe Tempdb as the name implies is used to store temporary data and data objects. Examples of this include temp tables and temp store procedures. It is important to note that when using this database all data and data objects are cleared from this database when SQL Server restarts. This database is also used by SQL Server when it is performing some internal operations. Typically, SQL Server uses this database for the purpose of large sort and index operations. Finally, this database is used to store row versions if row versioning or snapsot isolation transactions are being used by SQL Server. Additionally, I would love to hear from others about their experiences using system databases, tables, and objects in a real world environments.
