  • [cli/linux] get plain text from raw emails (not attachments extraction)

    - by etuardu
    Hi, having a raw email as input (i.e. the text between "DATA" and "." sent by a smtp client) I need to extract the mail content (which I know is always text only) as plain text. This means decoding transfer encoding (if any: could be base64 or quoted-printable), merging mutiparts (if any), and stripping headers. I tried various tools that would do that: mewdecode, uudecode, uudeview... I only managed to get this last one to work, but it won't output anything if the mail is not MIME encoded and it stores its output in an unpredictable (nor forceable) filename, so it's hard to use it in a not-interactive shell script. Since this is a pretty common job (every mail client have to do that), it's weird it's so complicated. Do you have some hints? (Actually, forcing uudeview to output in a certain file would be good enough). Thank you!

  • equivalent to getch(), mac/linux crash

    - by acidzombie24
    Hey guys. So I am using getch() and my app crashes instantly. Including when doing: int main() { getch(); } I can't find the link but supposedly the problem is, it needs to turn off buffering or something strange along those lines and I still want cout to work along with cross platform code. I was told to use std::cin.get(), but I'd like the app to quit when a key is pressed, not when the user typed in a letter or number then press enter to quit. Is there any function for this? The code must work under Mac (my os) and Windows.

  • Mono Project: How to install Mono framework on Red Hat Linux which is compiled on centOS ?

    - by funwithcoding
    We have Red Hat Enterprise Linux servers at work place. However we dont have Red Hat Linux desktops. So I used CentOS 5.4 to compile the Mono sources and generated the Mono framework for CentOS and tested with some sample codes and I am satisfied. I want to transfer this compiled framework to Red Hat Enterprise Linux 5. How Can I do that? Do I have to compile the Mono framework statically or do I have to copy the linked libraries as well? I am not familiar with linux much. Any help is highly appreciated.

  • What needs to be considered when setting up for Linux Development? [closed]

    - by user123586
    I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

  • Why would Java classloading fail on Linux, but succeed on Windows?

  • What does the kernel boot parameter "set acpi_osi=Linux" do?

    - by AIB
    I am facing an issue with brightness control in my laptop which has Intel HD graphics. So when I searched for a fix I found that a common suggestion is to edit the GRUB file line, GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" So could anyone tell me what the kernel boot option acpi_osi=Linux do? My OS is Ubuntu 10.10 64-bit version update The boot parameter acpi_osi is used as follows, acpi_osi= [HW,ACPI] Modify list of supported OS interface strings acpi_osi="string1" # add string1 -- only one string acpi_osi="!string2" # remove built-in string2 acpi_osi= # disable all strings But still I don't find a reason why this should fix any laptop issue!!

  • Why does Linux/Ubuntu have an unorganised install solution?

    - by Matthew
    I started using Windows 7 again to play some of my games I had been missing and I have to say I've been relieved to be reintroduced to the standard installation area "Program Files". From what I've noticed on almost every Linux distribution there is like 5 different areas where games/programs or other odds and ends end up. When you install something, I feel as though you pretty much have to guess where it installed at. Which honestly don't make any sense to me. So my question is, why does it appear as though there is no standard on Linux/Ubuntu? I'm not saying it's a bad thing. I just want to understand the reasons behind it.

  • Ubuntu Variant / Linux Distros which uses least system resources (RAM, CPU)?

    - by elegantonyx
    I have a netbook (an older Asus EEEPC 1005HA) which I want to get rid of Windoze on (I like Windows, but I don't think it works well in a netbook environment). Basically, my question is which Ubuntu variant will use the least RAM and CPU running idle, and/or the same question except when running Firefox and Libreoffice Writer, say. I am also open to suggestions of non-Ubuntu Linux distros, but since this is AskUbuntu I thought the first question would be more appropriate. I have a disk drive which I can attach to the netbook, so it doesn't have to be a Ubuntu Variant / Linux Distro which solely boots from a USB drive. I have at my disposal: DVDs, DVD writer/ disk drive, 4gb flash drive, 8 gb flash drive I was thinking either Lubuntu or Archbang / Crunchbang but I would like some help from more knowledgable people Specs: Can't boot into it right now, but I think I have either Intel Atom N270 @1.60ghz OR Intel Atom N280 @1.66ghz (single core, I think) 2gb RAM 160 GB hard drive

Tout du moins l'espère-ton, tant il est vrai que SCO, une société qui s'est spécialisée dans les attaques juridiques en rapport avec les brevets informatiques liés à UNIX et Linux, s'est montrée jusqu'ici acharnée.

    Un patch de 60 lignes règle les problèmes d'alimentation du noyau de Linux Son auteur est ingénieur chez RedHat Depuis quelques temps (depuis la version 2.6.36 du noyau pour être précis), les critiques se faisaient de plus en plus nombreuses de la part des utilisateurs de Linux contre la consommation électrique de plus en plus importante du kernel de l'OS. Que la communauté se rassure, ce désagrément devrait être rapidement (et certains diront : enfin) réglé grâce à un patch dont les premiers détails ont été publiés début novembre. Ce correctif ne compte qu'une soixantaine de lignes de code mais il devrait pouvoir définitivement régler les problèmes de régression li...

    Kernel Linux : la version stable 2.6.38 est disponible Elle optimise la fonction de résolution de la couche VSF La version stable 2.6.38 du noyau Linux vient d'être rendue disponible et annoncée officiellement par Linus Torvalds. Cette version apporte des améliorations importantes au niveau des performances. Le Kernel intègre désormais le support transparent des « huge pages » (TPH) qui permet d'obtenir de meilleures performances sur des charges de travail qui nécessitent beaucoup de mémoire (on pense aux serveurs JVM et serveurs de base de données). TPH utilise des pages mémoires de grandes tailles (2 Mb) par opposition aux pages traditionnels de 4 Ko. Une autre nouveauté est l...

  • Linux 3.6 sort en version stable : veille hybride, TCP Fast Open, VFIO, améliorations de Btrfs et suppression du cache IPv4

    Linux 3.6 sort en version stable ajout de la veille hybride, TCP Fast Open, VFIO, améliorations de Btrfs et suppression du cache IPv4 Linus Torvalds vient d'annoncer la sortie de la version 3.6 stable du Kernel Linux. La nouveauté phare de cette mouture est l'introduction d'un mode de veille hybride, longtemps supporté par Windows et Mac OS X. L'option Suspend to Both (Veille et hibernation combinée) permet de suspendre l'activité de l'ordinateur tout en conservant le contenu de la mémoire vive sur le disque dur (uspend-to-disk) et ensuite une sauvegarde du système dans la mémoire (suspend-to-RAM).

    La Linux Fondation arrache une solution de contournement pour le Secure Boot de Windows 8 Qui empêche le démarrage d'autres systèmes sur les PC certifiés Depuis que Microsoft a opté pour le ?Secure Boot? pour les PC sous Windows 8, un grand désarroi règne dans la communauté Linux. Cette fonctionnalité de démarrage sécurisé, directement intégrée à l'UEFI (interface micrologicielle extensible unifiée), empêche de facto l'installation de tout autre système d'exploitation. Microsoft transmet en effet une signature numérique aux constructeurs de cartes mères certifiées Windows 8.

  • Why doesn't java.util.Set have get(int index)?

    - by Marty Pitt
    I'm sure there's a good reason, but could someone please explain why the java.util.Set interface lacks get(int Index), or any similar get() method? It seems that sets are great for putting things into, but I can't find an elegant way of retrieving a single item from it. If I know I want the first item, I can use set.iterator().next(), but otherwise it seems I have to cast to an Array to retrieve an item at a specific index? What are the appropriate ways of retrieving data from a set? (other than using an iterator) I'm sure the fact that it's excluded from the API means there's a good reason for not doing this -- could someone please enlighten me? EDIT: Some extremely great answers here, and a few saying "more context". The specific scneario was a dbUnit test, where I could reasonalby assert that the returned set from a query had only 1 item, and I was trying to access that item. However, the question is more valid without the scenario, as it remains more focussed : What's the difference between set & list. Thanks to all for the fantastic answers below.

  • how to create a linked list in java without using util package? [closed]

    - by aparna
    I do not want to use any of the elements of the UTIL package. I tried but I am not able to get to the next node. Can anyone please help me out? Thanks in advance. I have put up this much. public class Element { private String s; private Element next; } public Element(String s) { this.s = s; this.next = null; } public void setNext(Element e) { this.next = e; } public String getString() { return this.s; } public Element getNext() { return this.next; } public String toString() { return "[" + s + "] => "; } public void add(String s) { int index = 0; System.out.println("Adding at index: " + index); Element curr = new Element(s); Element e = this.data[index]; if (e == null) { this.data[index] = curr; return; } while(e.getNext() != null) { e = e.getNext(); } e.setNext(curr); } }
