• How would I know if my OS is compromised?

  - by itsols

  I had opened a php folder from a friend's web host. I run it on mine to fix some bugs. Then I tried attaching the code to be emailed and GMAIL stated that the attachment was infected by a virus. Now I'm afraid if my Apache or OS (12.04) is infected. I checked the php files and found a base64 encoded set of code being 'eval'd at the top of each and every php file. Just reversing it (echo with htmlspecialchars) showed some clue that there were sockets in use and something to do with permissions. And also there were two websites referred having .ru extensions. Now I'm afraid if my Ubuntu system is affected or compromised. Any advice please! Here's my second run of rkhunter with the options: sudo rkhunter --check --rwo Warning: The command '/usr/bin/unhide.rb' has been replaced by a script: /usr/bin/unhide.rb: Ruby script, ASCII text Warning: Hidden directory found: /dev/.udev Warning: Hidden file found: /dev/.initramfs: symbolic link to `/run/initramfs'

• Inputting cheat codes - hidden keyboard input

  - by Fibericon

  Okay, here's what I want to do - when the player is at the main menu, I want them to be able to type in cheat codes. That's the only place I want it to work. I don't want to give them a text box to type into. Rather, I want them to simply type in a word (let's say "cheat", just for simplicity sake) that activates the cheat code. I only need to capture keyboard input when the window is in focus. What can I do to accomplish this?

• place to host a simple php socket server

  - by bonusbox

  i am running a small project that occasionally requires me to run a php socket script through ssh. it uses a few bytes of bandwidth (just some text) which activates my art installation project. i tried a simple web hosting plan but that didn't support sockets, so know i am using a 32$ vps plan on namecheap.com just to run a simple php script. i don't really need to host anything else on it. i find it kind of excessive for such a simple thing. is there a place i can run my script for a lower cost? any servers that support php sockets and ssh?

• Editing a command-line argument to create a new variable

  - by user1883614

  I have a bash script called test.sh that uses command-line argument: lynx -dump $1 > $name".txt" But I need name to be created from the argument by specific keywords in the argument. An example is: http://www.pcmag.com/article2/0,2817,2412941,00.asp http://www.pcmag.com/article2/0,2817,2412919,00.asp Both are two separate articles but are the difference can only be seen in those 12 characters. How do I create a variable from a url for those 12 characters? So that when I run test.sh in Terminal: ./test.sh http://www.pcmag.com/article2/0,2817,2412941,00.asp there is a text file saved as 0,2817,2412941,00?

• How can I write data to a file that users can't easily edit?

  - by ThePlan

  While working on game saving and loading I figured I could just write all the variable values to a file and then load that file from it's default location anytime. However from the very beginning it sounded like an odd job. I know about serialization and boost, but that seems so complicated, I figured I'd keep it simple, but I've ran across this huge issue: No matter what file I can write with C++, the user can get their hands on it, they can edit their position, they can remove a boss, or add new weapons for themselves. My question here is: How can I create a file in C++ which cannot be editted or openned with a text editor such as Notepad (I'm not trying to make a file which is impossible to open, but a file which will give the user a headache if he tries to edit it through usual methods.)

• How to refuse to give an access to passwords to a customer without being unprofessional or rude?

  - by MainMa

  Let's say you're creating a website for a customer. This website has its own registration (either combined with OpenID or not). The customer asks you to be able to see the passwords the users are choosing, given that the users will probably be using the same password on every website. In general, I say: either that it is impossible to retrieve the passwords, since they are not stored in plain text, but hashed, or that I have no right to do that or that administrators must not be able to see the passwords of users, without giving any additional details. The first one is false: even if the passwords are hashed, it is still possible to catch and store them on each logon (for example doing a strange sort of audit which will remember not only which user succeeded or failed to logon, but also with which password). The second one is rude. How to refuse this request, without being either unprofessional or rude?

• Importance of frequency of keywords for SEO [closed]

  - by Calle

  Possible Duplicate: keyword stuffing in SEO I've seen a few posts on here and elsewhere that talk about the amount of unique keywords used, or aimed, for in a text. But how important is the frequency of keywords for SEO optimized copy, the higher the better? Is there a certain percentage to aim at? For example, I currently have copy aimed for a specific keyword. The rate of this keyword is that it makes up 2% of all words. Is this too low? Too high? The higher the better?

• How best to merge/sort/page through tons of JSON arrays?

  - by Joshiatto

  Here's the scenario: Say you have millions of JSON documents stored as text files. Each JSON document is an array of "activity" objects, each of which contain a "created_datetime" attribute. What is the best way to merge/sort/filter/page through these activities via a web UI? For example, say we want to take a few thousand of the documents, merge them into a gigantic array, sort the array by the "created_datetime" attribute descending and then page through it 10 activities at a time. Also keep in mind that roughly 25% of these JSON documents are updated every day, and updates have to make it into the view within 5 minutes. My first thought is to parse all of the documents into an RDBMS table and then it would just be a simple query such as "select top 10 name, created_datetime from Activity where user_id=12345 order by created_datetime desc". Some have suggested I use NoSQL techniques such as hadoop or map/reduce instead. How exactly would this work? For more background, see: Why is NoSQL better for this scenario?

• Ubuntu 12.04, Intel Centrino 1030 Wireless-N 1030 not able to connect to wireless

  - by playcat

  I saw several similar threads, but none really does it... I have 12.04 precise x64 installed and things worked great for some 10 days. Then it all stopped - I wasn't able to connect any more. Even more, things were so scre*ed up that it were showing other network's name while connecting :( I have an Asus K53SM-SX054. Here's the text from dmesg related to my card: http://fixee.org/paste/iaw23iw/ Basically, it's Intel Centrino Wireless-N 1030. Not sure if it's important, I had Gnome with unity and then moved to KDE. Any ideas what to do? I'm on the verge of reinstalling things, but I already set plenty of things and have some things that I'd need to back up... and I'm rather lazy to go on with it :) EDIT: My wlan network is hidden. Not sure if this should have any influence.

• Let apache run perlscripts that don't have an extension

  - by tiMbeRdroP

  I'd like to use perlscripts without their extension. f.e. "index" instead of "index.pl". Changing the DefaultType-directive from text/plain to application/x-perl didn't do the trick. Instead of running the script the server offered to download its source. I'm not exactly sure if changing this directive is the right approach. Telling apache to read the shebang-line when there is no extension sounds much better to me. I hope someone with more experience on this topic can help me out.

• How Data Transfers differ on Smart Phones: Iphone vs. Android vs. Windows Phone

  - by MCH

  I am interested in how each individual smart phone is allowed to handle data transfers within a third-party app. I am interested in designing apps that allow customers to update, transfer, download, etc. data from their smart phone to their personal computer and vice-versa. (Ranging from just text, to XML, to a Relational Database) I only have experience with the Ipod Touch before and one particular app that maintained all the data on an online server, so to update the data on your pc or iphone you had to go online, are there other ways to do it? Like bluetooth, wireless LAN, USB, etc? I believe Apple has certain policies on this in order to control the App Store and individual Iphones. I suppose each company has a particular policy on how an app is allowed to transfer data to another system, does anyone have a good understanding of this? Thank you.

• Syncing objects to a remote server, and caching on local storage

  - by Harry

  What's the best method of sycing objects (as JSON) to a remote server, with local caching? I have some objects that will pretty much just be plain-text with some extra meta-data. I was thinking of perhaps including a "last modified date" for both Local storage and Remote storage. This could then be used to determine which object is the most recent. For example, even though objects will be saved to both local and remote when they are saved, sometimes the user may not have internet access, or the server may be down, or any other number of things. In this case, the last modified date for remote storage would be reverted to its previous date. Local storage would remain as it is. At this point, the user could exit the application, and when they reload the application would then look at the last modified dates of the local and remote storages, and decide. Is there anything I'm missing with this? Is there a better method that I could use?

• Powershell progress dialogs

  - by Norgean

  Creating nested progress dialogs in Powershell is easy. Let the code speak for itself: for ($i = 1; $i -le 2; $i++) {     Write-Progress -ID 1 -Activity "Outer loop" -Status "Tick $i" -percentComplete ($i / 2*100)     for ($j = 1; $j -le 3; $j++)     {         Write-Progress -ID 2 -Activity "Mid loop" -Status "Tick $j" -percentComplete ($j / 3*100)         for ($k = 1; $k -le 3; $k++)         {             Write-Progress -ID 3 -Activity "Inner loop" -Status "Tick $k" -percentComplete ($k / 3*100)             Sleep(1)         }     } } I.e. some text that explains what we're doing (Activity and Status), and ID numbers. Easy.

• Why can't flowcharts or mathematical equations created in Microsoft Office and saved in .docx format be opened by LibreOffice?

  - by user33831

  I am using Ubuntu 11.10 and LibreOffice that comes with it. Before this , I was a Windows user and some of my previous documents were saved in .docx format. I tried to use LibreOffice to open those .docx file and I can view all text, however I can't view the flowchart I drew and also mathematical equations. Another issue is, if I create new flowchart with LibreOffice and save it in .docx file, when I re-open that file, I can't view those flowcharts, but those flowcharts are there, occupied space. No problem for .odt format of course. Does anyone know why this happens? Thanks in advanced.

• How do I POST XML generated to a URL in C#

  Hi guys an new to C# and i need help, am trying to send XML generated to a URL, I keep getting error with HttpWebResponse.

• How do I change the cursor and its size?

  - by Thomas Le Feuvre

  I have recently created an Ubuntu 12.04 partition on my Windows 7 laptop. When installing it, I switched to "high contrast" mode, which has rather large cursors (by large I mean about twice as large and thick as they should normally are). Now I have successfully installed the partition, the large cursors have stuck around even after exiting this high contrast mode, but only when I am hovering over stuff e.g. hovering over text inputs, links, and when resizing windows. All of these cursors are too large. They cursor is only normally sized when the computer should be displaying the normal mouse pointer. Does anyone know how I might go about fixing this?

• Should I change the name in the WTFPL?

  - by Domenic

  I'm using the WTFPL in my personal projects published on GitHub. Currently I'm using it verbatim, but I have the suspicion I shouldn't be leaving Copyright (C) 2004 Sam Hocevar <[email protected]> in there, and instead should use my name. But the license is very confusing about this. Half of the WTFPL is about the WTFPL itself, so I thought that copyright might refer to a copyright on the license text itself, and not on the project this is licensing. Also, it says Everyone is permitted to copy and distribute verbatim or modified copies of this license document, and changing it is allowed as long as the name is changed. So would I have to change the name, from WTFPL to, say, "WTFPL-Domenic"?

• What to use to make voice chat (and some more) on a web?

  - by Tunococ

  I am trying to make available on my website a voice chat for a small group of people that allows some other means to interact such as text messaging, photo sharing, file sharing, simple drawing and silly games. In other words, something similar to older MSN Messenger, but on the web. Any ideas on what to use? To clarify, I am looking for suggestions on languages and libraries to use. I want to be able to fully customize it as much as possible because I might want to add other (somewhat interesting) functions later. Low-level programming is fine if required, but platform dependency isn't that much preferred.

• C# Rendering Engine for Roguelike [closed]

  - by Haedrian

  I'm trying my hand at designing a roguelike, and I need a pretty simple 2D rendering engine that works with C# Its as simple as it gets, I want to be able to drop sprites somewhere on a grid, with some sort of menus/text on the side; that sort of thing. The (very complicated) game itself would be decoupled from the interface I've looked into a number of engines and they all seem to be very complicated/support much more things than I need. Right now I'm planning on making my own using either XNA or OpenTK - but I was wondering whether anyone has any suggestions for less-complicated rendering engines which might make my job easier. Thanks.

• Collisions on complex map 2D

  - by waxx

  I'm currently thinking about collision and map system that I want to use in my next game and I'm kind of puzzled. Maps are going to be somewhat complex with lots of irregularities and thus tiling is out of question. I thought about an editor where you'd draw rectangles on the map that would represent areas that are collidable with and then saving such "collision map" with only black/white gfx. Or maybe should I save exact rectangles data with their x/y/width/height into some text file and go from there? What would you recommend? Thanks.

• Is this fix for Avast Antivirus crashing safe to use?

  - by TmRn

  Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: Press Ctrl+Alt+T to open the Terminal. When it opens, run the command below. sudo gedit /etc/init.d/rcS Type your password and hit Enter. When the text file opens, add the line: sysctl -w kernel.shmmax=128000000 Make sure the line you added is before: exec /etc/init.d/rc S This is what it should look like: #! /bin/sh # rcS # # Call all S??* scripts in /etc/rcS.d/ in numerical/alphabetical order # sysctl -w kernel.shmmax=128000000 exec /etc/init.d/rc S Save the file. Reboot. My question is: Did I do anything wrong? I mean as I have made some tweaks, will it lower the security of Avast down like viruses do? Please if you are a programmer check this if it contains bug or harmful intentions... Thanks.

• App for finding icons easily?

  - by artfulrobot

  Occasionally I need to use a custom icon for something - a launcher created with alacarte, a custom .desktop file, or just a particular folder viewed in Nautilus. I know there are LOADS of cool icons installed on my system at /usr/share/icons but browsing them is really awkward. Everything is scattered around, duplicated in different sizes (or symlinked to .svg) etc. So, say I'm looking for a text file icon, or a purple folder or such, searching is a faff, and then when you do find results you need to work out what the best quality one is. Made me think that someone might have written an app for this?

• Visual Studio Setup - why is solution explorer on the right?

  - by amelvin

  Every time I install VS (whichever version going back years) it installs with the Solution Explorer on the right. Now as most UIs have the navigation in a left hand column (and at the top of the viewport) and the content to the right of this navigation this always seems wrong to me. So I drag the solution explorer to the left of the screen and dock it there. But I've never seen another developer do this. Considering how most programmers usually like to customize their environment, adding their favourite text editor, browser, plug-ins, greasemonkey scripts etc why do Visual Studio developers never seem to make this simple UI change? Does anyone else do this or am I just screaming in the dark?

• Will Google penalize my website if I hide the H1 tag?

  - by mickburkejnr

  I've read an article today where the author stated that if you put keywords on to your page but then hide them with CSS, Google will penalize your site. This make sense. This got me thinking though about my own technique when I build a website. If for example when I build a website and the logo contains the name of the website, I tend to put the name of the website in a H1 tag and then hide this tag. I don't know why I do it, I've always done it. I also include any text held in an image in the alt attribute of the img tag. But because I am hiding the H1 tag, does this leave me open to Google penalizing the website because I've hidden this one tag?
