    I have two USB Flash . A USB flash load software after Linux boot and other USB Flash load other software on MS -Dos, I would like to merge the two into a single USB flash and when the boot starts must appear which one I desire to boot ( and when we done the project, We can also change the boot sequence when we needed , either by Grub - text file or any boot system that you use in this project ) . For those who want to examine one of the USB Flash follows the download link : www.acronus.com.br/files/first_usb_flash.imgNote: This first USB Flash consists of two partitions: * The smallest partition we have all the settings that the software / game saves in xml file format. * The second partition (the largest one ) is in raw data format ( 0x83 ) . We need access to the files of the structure of this USB flash to boot and edit the Grub file, but we have to get ready after the project to maintain its current format ( files hidden or inaccessible configuration, creating a certain difficulty in access or changes in structure of the boot, like is already done in the second partition -raw data format ) . In short , we have to have information to allow us access, just to change the boot and protect it in the same pattern again.

    I have a lot of various formats, qualities and dimension/aspect ratio video files (mpeg, AVI, mp4, mkv, etc) that I want to be transcoded to a reasonable quality (perhaps it can be a configurable variable in the script), while maintaining the aspect ratio, and normalizing the video and audio to the same reliable defaults. Some video files have too high of quality audio, I don&quot;t need extremely high quality audio. A lot of videos can be downgraded to standard definition video quality. I have some videos I have downloaded that are in 1080p format at 2 gigabytes, and the same videos are in some smaller format/smaller bitrate and are only 200-300 megs and still decent quality.I will definitely provide samples of videos as needed. I haven&quot;t found anything decent so far. If you know anything about video scene ripping packs, it would probably be something close to that. I expect it will use ffmpeg, and want it to run on Linux and from bash. Should accept two parameters - input file and desired output file.For example:./foo.sh input.mkv output.mp4foo.sh can include a couple minor tweaks, but ideally it will have solid defaults. I would try to do this myself but ffmpeg has a lot of options, I am not guaranteed I can maintain the aspect ratios properly, and I don&quot;t trust myself.I don&quot;t expect this to be a very intense/involved project, but someone with ffmpeg/video transcoding experience probably can handle it quite well. HandbrakeCLI comes close to what I want but still has too many options.

    In this phase you will write a function called locateFacilities that takes as parameters thedata structure you built in Phase 1 and a nonnegative real number r (representing the radius ofcoverage) and returns a list consisting of cities at which facilities were located. More specically,you should use the following function header:def locateFacilities(data, r) .The list of cities returned by this function should be in alphabetical order.This function should implement the greedy algorithm described in the section titled \The facilitylocation problem.&quot; Within the function locateFacilities, you might want to use an additionaldata structure called served that keep tracks of which cities have already been served by thefacilities located thus far. The served data structure could simply be a boolean list of length128, initialized to all False values. The element in position i in this list indicates whether city i(i.e., the city in position i in the list cities) has been served or not. Once such a data structurehas been dened, you can then nd out for any given city c the number of cities, not yet served,that are within radius r of c (you should write a function for this!). If you implement this, thegreedy algorithm is easy to complete because it repeatedly locates a facility at a city c for whichthe number of \unserved&quot; cites within radius r of c is maximum.Plus the MOST IMPORTANT THING: I want the code to be written in very beginner&quot;s format. Like the code I wrote in phase 1. It should not contain any advanced topics. And Phase 1 solution/code has been added so please refer to it. And my budget for this is 10-13 dollars.(we can negotiate,) And I need this within in 20 hours.(Thursaday 9AM USA timing) If interested please contact me.

    We have an MFC project on Compact 7 that uses INI and SETTINGS classes to load / save an applications settings. The class works but is proving to be too slow. The files are stored in NANDFlash on our embedded board.So the task is to create something that works in the same way but faster.The way it is used in our app is that all the fields are loaded on start of the app and then occasionally the user might change something. So its expected that the new method will include loading the entire ini file into memory... Modify the values and then later save the entire file back.Attached are the classes and a sample ini file. I cannot supply more of the project.

    I&quot;d like you to develop an alternative to Wingpanel for Linux Desktop running X window.That&quot;s basically a panel which sits at the top of Linux desktop screen, shows date and some icons.It will be written in C or C++ or whatever, which can be compiled in Linux using Makefile. No java, no python, no such things, please.See attached pictures to get an idea how it should look like.Features:- it must not depend on any libraries. If you essentially need it to depend on something, like GTK+3, we can discuss that, but I prefer if it&quot;s absolutely standalone without any dependencies. It will of course depend on Xorg libs and header files, no problem in that. However the panel should work even if only pure Xorg is installed in the system.- configurable in a text config file, no GUI for config at the moment- automatically adjusts its size based on its length- always stays at the top of the screen/desktop- dragging the panel by user can move it left & right, but not up/down- possibility to configure it to stay on top above any other windows- possibility to configure it to auto hide, and auto-show when mouse touches the top screen edge- the application will not be square, so you&quot;ll probably need to resolve transparency- if the panel is hiding, there will be animation (slide up). Similarly showing will slide down.Shows:text, iconsIt will be your task to also design the configuration file format, so it allows custom look, for example some users will need three textual informations there (like CPU usage, date, free RAM), while some other users will want to see icons first and date at the end, etc.Now how the panel is populated by text and icons. This is the tricky part.The user will be able to configure the panel in configuration file. This file will be of variable size, thus some users may configure it just to show date, some other users will need icons, lots of other text, and so on.All elements in the panel are a result of running bash commands mentioned in the configuration file. For example, if the first element should display current date/time, the user will simply configure that the output of &quot;date&quot; linux command will be printed there. If an icon is to be It should be also possible to configure how often the command gets re-executed to refresh the status. It may be an integer in seconds (for example the date/time area will need to be updated only once per minute), or it can be configured as &quot;hover&quot;, here the item will be updated every time user hovers mouse over it, or it can be set to &quot;click&quot;, where the item will be updated on click.Clicking any of the element will run a command configured by the user. Thus, if user specifies that &quot;calendar&quot; application is started when he clicks on the date, it will simply do that. So you need to keep this in mind in designing the config file format.It needs to be also possible to &quot;ping&quot; the panel somehow (either using socket or pipe or something), so other applications can communicate that the panel needs updating (refresh).Icons will be 16x16px.Examples:- date will be displayed by &quot;date&quot; linux command, and will need to refresh once per minute- icon for sound volume will be diplayed accordingly to output of &quot;sndvol&quot; script, which simply prints full path to the icon file as output, nothing else.There can be one configuration file for pannel settings, and another configuration file for items.Proposed configuration file for panel:[general]autohide=falseProposed configuration file for items:[date_section]command=date +&quot;%m-%d-%y&quot;update=60onclick=/sbin/calendar[sound_volume_section]command=sndvol -vupdate=hoveronclick=/sbin/alsamixerThe panel should listen on a socket or pipe or something, and if it receives command &quot;update&quot;, it updates all elements. If it receives command &quot;update sound_volume_section&quot;, it updates only that part [sound_volume_section]Example design is attached.License: your software will be released under GNU GPL license.

Android Diskless System

8th Annual International Joint Conferences on Computer, Information, Systems Sciences, & Engineering.

Abstract—In this paper we propose the Android Diskless<br />System, which provides a set of tools to boot and manage diskless<br />computers on a LAN. The motive is to use old computers, still<br />in good conditions but without a hard drive, for a general<br />purpose environment such as school labs or small businesses<br />like cyber cafes. The resulting solution allows users to connect<br />to the Internet, store their data, play games, and interact with<br />documents (pdf, doc, xls, ppt) and media, which is the common<br /><br />use of c
