  • What are the technial and programming requirements for writing a stealth keylogger?

    - by user970533
    I'm planning to write/code one such stealth keylogger that would bypass detection by a certain antivirus. (I don't want to name the vendor as I know how good Google queries are against StackExchange websites). I don't want to just download any keylogger from internet and try to encode it to evade detection. Writing code myself I would have the ability to make changes as I go; obscuration on both high-level and low-level language. I like control too. It seems naive but is it true that keyloggers are a thing of the past, probably because of how effective AV's have become in detecting such programs? I want some nice points on how can one easily write a robust, effective key logger preferably for a Windows environment?

  • Customizing Texmaker

    - by Gabriel Furstenheim
    I use LaTeX a lot but I find quite obnoxious all the crappy files it leaves behind when you compile: .aux, .log... Fortunately TeXMaker has the option "clean" that deletes all of these. However, I don't like having to remember to click on it every time I'm going to close a document, ie I'd like a button that both closes a document and cleans all that stuff. Any hint as how to do it? I suppose if I knew how to access the program code I'd be able to do it as I'd just have to put together two options that already exist. Thanks

  • I'm having trouble understanding these exercises wording.

    - by KasHKoW
    Exercise 1-20. Write a program detab that replaces tabs in the input with the proper number of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every n columns. Should n be a variable or a symbolic parameter? Exercise 1-21. Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab. When either a tab or a single blank would suffice to reach a tab stop, which should be given preference? could you paraphrase these for me. thanks

  • Application to organize / manage installed networks

    - by vicmp3
    I was wondering if there is a Application where you can organize networks. I mean if you have installed some networks you have to note every pc's name, his ip-address and so on. Is there a Application where you can manage it? I saw the monitoring tools but that is not exactly what I'm looking for. Maybe I didnt explain me well, after all my englis his not so good :) For example if I install many different networks I write in a book how I configured them. I write pc-name ip-address ip-gateway ip-broadcast and so on for each network. It will be great if I can do it in a program to organize it well, and for example it gives me a node view of the network.

  • Saving mobile application data when no service?

    - by Abe Miessler
    Say I have a mobile application that allows users to enter information which is then uploaded to a central location. I had planned on building this using only HTML5 and javascript (non-native app), but I'm assuming if someone is in an area where there is no service they simply will not be able to use the app. As a work around would it be possible to write a native app that saves the information on the device and then uploads it whenever service returns? If so, is it possible to write a native app entirely in HTML5 and Javascript that does this?

  • How to design a game engine in an object-oriented language?

    - by chuzzum
    Whenever I try and write a game in any object-oriented language, the first problem I always face (after thinking about what kind of game to write) is how to design the engine. Even if I'm using existing libraries or frameworks like SDL, I still find myself having to make certain decisions for every game, like whether to use a state machine to manage menus, what kind of class to use for resource loading, etc. What is a good design and how would it be implemented? What are some tradeoffs that have to be made and their pros/cons?

  • FFmpeg multi pass encoding

    - by Levan
    Sorry, I am really new to this, and have problems doing some tasks without help. So I have a terminal command: ffmpeg \ -y \ -i '/media/levan/BEEA60D8EA608E89/Downloads/Videos/Tony Braxton - Un-Break My Heart.VOB' \ -s 1920x1080 \ -aspect 16:9 \ -r 25 \ -b 15550k \ -bt 19792k \ -vcodec libtheora \ -acodec libvorbis \ -ac 2 \ -ar 48000 \ -ab 320k \ ddd.ogg and I want to have 3 pass video in output video, but how do I accomplish this? I found that I must write -pass n command some where, but where to write it I do not know. I tested this and wrote -pass 3 at the end but then the terminal just showed a > symbol.

  • Google new algorithm: My company have a 40 sites with different domains that some of their articles appears in my main website

    - by user5674576
    Hi, My company have a 40 sites with different domains that some of their articles appears in my main website with reference to their source. Our articles write by high level processionals in the field that they write about - we also pay them high salary. In recent google algorithm change my main site rating down very seriously. What should we do to restore company main site google rating? our solution and ideas that not working well: rel="canonical" to source website (we already have it before google change without results) meta "original-source" but not have rating influence (we already have it before google change without results) Edit:: maybe we should delete rel="canonical" from main website articles that refer to our other small websites (because this articles in main website not indexed in google)? Thanks in advance

  • Adding JavaScript to your code dependent upon conditions

    - by DavidMadden
    You might be in an environment where you code is source controlled and where you might have build options to different environments.  I recently encountered this where the same code, built on different configurations, would have the website at a different URL.  If you are working with ASP.NET as I am you will have to do something a bit crazy but worth while.  If someone has a more efficient solution please share. Here is what I came up with to make sure the client side script was placed into the HEAD element for the Google Analytics script.  GA wants to be the last in the HEAD element so if you are doing others in the Page_Load then you should do theirs last. The settings object below is an instance of a class that holds information I collection.  You could read from different sources depending on where you stored your unique ID for Google Analytics. *** This has been formatted to fit this screen. *** if (!IsPostBack) { if (settings.GoogleAnalyticsID != null || settings.GoogleAnalyticsID != string.Empty) { string str = @"//<!CDATA[ var _gaq = _gaq || []; _gaq.push(['_setAccount', '"  + settings.GoogleAnalyticsID + "']); _gaq.push(['_trackPageview']);  (function () {  var ga = document.createElement('script');  ga.type = 'text/javascript';  ga.async = true;  ga.src = ('https:' == document.location.protocol  ? 'https://ssl' :  'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0];  s.parentNode.insertBefore(ga, s);})();"; System.Web.UI.HtmlControls.HtmlGenericControl si =  new System.Web.UI.HtmlControls.HtmlGenericControl(); si.TagName = "script"; si.Attributes.Add("type", @"text/javascript"); si.InnerHtml = sb.ToString(); this.Page.Header.Controls.Add(si); } } The code above will prevent the code from executing if it is a PostBack and then if the ID was not able to be read or something caused the settings to be lost by accident. If you have larger function to declare, you can use a StringBuilder to separate the lines. This is the most compact I wished to go and manage readability.

  • Is client side JavaScript capable of replicating the Node.JS module loading system?

    - by jt0dd
    I like the Node.JS style of JavaScript, where I can write all of my functionalities into smaller files and then require those neatly from within my code. I'm even thinking about trying to write a framework to mimic that behavior in client-side JS. My goal would be to implement the module loading system as accurately as possible - See Module docs. For require(), I can use things detailed in answers to this question, most notably JQuery's $.getScript(). It seems to me that other aspects of the module loading system should be possible as well. So I'm asking more experienced programmers here first, before I waist my time: Is there something that I'm missing that's going to cause such an attempt to fail miserably, or can this be successfully done?

  • What's wrong with lualatex?

    - by Hooked
    I'm not sure if this is a bug or I've done something wrong (or I simply don't know luatex well enough). This minimal example file test.tex \documentclass{article} \usepackage{luacode} \begin{document} A random number: \begin{luacode} tex.print(math.random()) \end{luacode} \end{document} Should compile with lualatex test.tex but fails with: ! LaTeX Error: File `luacode.sty' not found. It sounds like something was messed up in the installation of luatex. They look to be installed: > dpkg --get-selections | grep luatex luatex install texlive-luatex install The file exists on my system: > locate luacode.sty /usr/local/texlive/2011/texmf-dist/tex/lualatex/luacode/luacode.sty so I'm not how to troubleshoot this. Is the package messed up or is it a problem on my end?

  • How do I get to the maintenace shell?

    - by Narida
    I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

  • Changing Your Design for Testability

    Sometimes I come across a way of putting something that it is pithy good, not Hallmark trite, but an impactful and concise way of clarifying a previously obscure concept. A recent one of these happy occurrences was when I was reading the excellent Art of Unit Testing by Roy Osherove. After going through the basics of why youd want to test code and how to do it, Roy confronts a frequent objection to having unit tests, that it ends up changing how you design your components: When we write unit tests for our code, we are adding another end user (the test) to the object model. That end user is just as important as the original one, but it has different goals when using the model.  The test has specific requirements from the object model that seem to defy the basic logic behind a couple of object-oriented principles, mainly encapsulation. [emphasis added by me] When I read this, something clicked for me. I used to find it persuasive that because unit tests caused you to change your design they were more disruptive than they were worth. The counter argument I heard is that the disruption was OK, because testable design was just obviously better. That argument was not convincing as it seemed like delusional arrogance to suggest that any one of type of design was just inherently better for the particular applications I was building. What was missing was that I was not thinking of unit tests as an additional and equal end user to my design. If I accepted that proposition, than it was indeed obvious that a testable design was better because now all users of my component would be satisfied. Have I accepted that proposition? Id phrase it slightly different. I find more and more that having unit tests helps me write better, less buggy code before it gets to production or QA. As I write more unit tests, it gets easier to see how to create testable components, so I dont feel like its taking me as much extra time up front. I pick and choose components that seem most likely to benefit from automated tests and it is working out nicely. If you already implement Test Driven Development, this whole post was probably a waste of your time <g> If you hate the idea of unit tests, well, probably not a great value prop for you either. However, if you are somewhere in between, at least take a minute and check out a sample chapter from Roys book at: http://www.manning.com/osherove/.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Are C or C++ The Only Viable Languages for a GC

    - by user95312
    Background I have just finished writing a compiler for a functional language compiling to the JVM as a learning project. However, since I'm just doing this to learn, I thought it might be interesting to write a native backend and a RTS for it. As I've been planning out what this new backend will look like, the one point I'm stumbling on is the garbage collector. I've implemented the compiler in Haskell. But I have no desire to write the GC in Haskell since, while it may be possible, it'd suck. Question I've looked at several FOSS garbage collectors prior to posting and most of them were implemented in good old ANSI C. Is this still the most accepted choice for writing a GC nowadays? I've seen that this site tends to frown upon questions with multiple answers so I hope this will make it more specific: If some startup was writing a professional grade gc today, are the only viable choice for them C or C++? It's my first question here so please comment and let me know if this question is ill-suited for for programmers.

  • TDD, new tests while old ones not implemented yet

    - by liori
    I am experimenting with test-driven development, and I found that I often come to a following situation: I write tests for some functionality X. Those tests fail. While trying to implement X, I see that I need to implement some feature Y in a lower layer of my code. So... I write tests for Y. Now both tests for X and Y fail. Once I had 4 features in different layers of code being worked on at the same time, and I was losing my focus on what I am actually doing (too many tests failing at the same time). I think I could solve this by putting more effort into planning my tasks even before I start writing tests. But in some cases I didn't know that I will need to go deeper, because e.g. I didn't know the API of lower layer very well. What should I do in such cases? Does TDD have any recommendations?

  • Xubuntu: how do I automatically mount external NTFS drive with writes allowed?

    - by user74372
    i would have thought mine was such a common question that there would be a simple solution already built in to xubuntu - but there isnt. i have 2 separate external hard disks and connect them to a usb port at different times - i would like them to be automatically mounted as read/write, but apparently the designers of gnome-volume-manager decided that shouldnt be possible and they are mounted as read-only in fact, i can write new files to them, but cannot then delete the new files i just wrote! is there a workaround? i read somewhere that etc/fstab doesn't apply to removable media, which are mounted by gnome-volume-manager and therefore cannot be unmounted by a user

  • Where to prepare (legal) "embeded" documents for the web [on hold]

    - by WHITECOLOR
    Say I have to have terms of use on site, a place the text as marked up html. Where it is better to prepare this document initially if it is going to placed to the web? Considering that such documents are prepared and changed by lawyers, it is not very applicable for them to use text editor. And it is not very efficient to manually process content to prepare it for the web as it is changed. For now my solution is: Prepare document text in google docs keeping some simple structure (title, ordered lit of features, simple paragraphs), save as html (it will contain some unnecessary markup) and then use custom conversion tool (some script) to convert saved html from google docs to simple html and inject new version to the site. What is common practiceses for this problem? What is the workflow of preparing and publishing such documents.

  • How to grant standard users access to disk partitions and flash storage?

    - by JK04
    I have a partition that I need standard users (not administrators)to have read/write access to. However, this partition does not even appear to them as it does to me as an administrator. How can I make it so that standard users can read/write to this partition? It would be nice if they could have the ability to mount it if needed. I have the same problem with removable media - if I have a flash card in the computer, the standard users cannot see this storage media.

  • How to have an Arduino wait until it receives data over serial?

    - by SonicDH
    So I've wired up a little robot with a sound shield and some sensors. I'm trying to write a sketch that will let check the sensors. What I'd like for it to do is print out a little menu over serial, wait until the user sends a selection, jump to the function that matches their selection, then (once the function is done) jump back and print the menu again. Here's what I've written, but I'm not a that good of a coder, so it doesn't work. Where am I going wrong? #include <Servo.h> Servo steering; Servo throttle; int pos = 0; int val = 0; void setup(){   Serial.begin(9600);   throttle.write(90);   steering.write(90);   pinMode(A0, INPUT);   pinMode(7, INPUT);   char ch = 0; } void loop(){   Serial.println("Menu");   Serial.println("--------------------");   Serial.println("1. Motion Readout");   Serial.println("2. Distance Readout");   Serial.println("3. SD Directory Listing");   Serial.println("4. Sound Test");   Serial.println("5. Car Test");   Serial.println("--------------------");   Serial.println("Type the number and press enter");   while(char ch = 0){   ch = Serial.read();}   char ch;   switch(ch)   {     case '1':     motion();   }    ch = 0; } //menu over, lets get to work. void motion(){   Serial.println("Haha, it works!"); } I'm pretty sure a While loop is the right thing to do, but I'm probably implementing it wrong. Can anyone shed some light on this?

  • Predicted target location

    - by user3256944
    I'm having an issue with calculating the predicted linear angle a projectile needs to move in to intersect a moving enemy ship for my 2D game. I've tried following the document here, but what I've have come up with is simply awful. protected Vector2 GetPredictedPosition(float angleToEnemy, ShipCompartment origin, ShipCompartment target) { // Below obviously won't compile (document wants a Vector, not sure how to get that from a single float?) Vector2 velocity = target.Thrust - 25f; // Closing velocity (25 is example projectile velocity) Vector2 distance = target.Position - origin.Position; // Range to close double time = distance.Length() / velocity.Length(); // Time // Garbage code, doesn't compile, this method is incorrect return target.Position + (target.Thrust * time); } I would be grateful if the community can help point out how this is done correctly.

  • How do I add pcie_aspm=force to my boot options?

    - by nargo7
    I just upgraded to 11.10 from 11.04 on my laptop (I don't have Windows) by downloading from the Ubuntu website. The laptop battery is in bad condition, but I was using it with the 11.04 plugged to AC all the time, and everything was fine. After installing 11.10, the laptop seems to not notice that it is connected to AC, so it shuts down a few minutes after starting. I read that I have to type pcie_aspm=force in the boot command, so I tried accessing it by pressing the "F6" key while booting, and then the other F keys, but nothing happened. I also found that I can write that instruction in the terminal window, but I don't know in which file or location. I would appreciate some help, but I am not a computer engineer, so please write the instructions in plain English.

  • How is your working time distributed between coding and thinking?

    - by mojuba
    ...in percentage. For example 60/40 or 90/10 or 100/0. My hypothesis is that the bigger the proportion of time you spend thinking the smaller your code can be as a result (and the less time will be needed to write it down). Think more, write less, in other words. Do you think it is true? As a side note, I think in typical software companies thinking is not part of the culture anyway: you are usually supposed to be sitting there at your computer typing something. You will almost definitely be noticed by your managers if you wander about with a blank look thinking over your next steps with your code. Too bad.
