In a surprising development that seems really strange and unnecessary, Firefox 2.0 won’t go to the previous page when I press the “backspace” button on the keyboard. I have grown used to this over the period I have used Firefox. The fact that I can’t use backspace the way I am used to has been annoying me no end. So I decided to dig a little deeper.

The feature was removed to fix a bug. But then, until the bug fix propagates to a firefox build available on Ubuntu, one has to resort to a little scratching to fix the matter. Here’s how you resurrect the backspace button in Firefox 2.0.

Automatix is a graphical interface for automating the installation of the most commonly requested applications in Debian based Linux operating systems.

Installing Popular Applications On Your Ubuntu Desktop With Automatix2


This tutorial was written while offline and without any kind of browser open. That’s right. You can blog right from your gnome-based desktop with the greatest of ease!

Tutorial for the day: Installing and blogging with Drivel.

To install Drivel you can use the basic methods we’re familiar with. Via the command line or from “Applications” > “Add / Remove” > search:Drivel. (command line “sudo aptitude install drivel”

You can then access Drivel from your Applications menu inside the Internet section.

Some times you want to use iSO images without burning them.If you don’t want to waste your CD’s/DVD’s here is the simple possible solutions using these tips you can mount and unmount ISO images without burning them.

I know two possible solutions

1) Using Nautilus Scripts
2) Using kernel loop module

Now we will see each one in detailed

There are times when people make mistakes, and manage to do crazy things to working systems. It wasn't so long ago that a hasty deletion caused me all kinds of problems. Recently I read of an unfortunate sysadmin who managed to recursively change permissions on their root filesystem - and here is my attempted solution.

The problematic command was:

(none):~# chmod -R 777 /

escuing a system with massively broken filesystem permissions


Still in this case, I had to install several times an older version of ImageMagick. Why? Not for the application itself, but because of some applications that relied on the php wrapper (the imagick pecl module). This compiles fine with ImageMagick 6, but many functions fail. So in order to have the php module working properly I had to first install imagemagick 5 that is the last version the php module works fine.

I will show how to install ImageMagick 5.5.7 (the latest version available from the 5 branch) from sources on a Debian Etch system. Debian obviously contains packages for ImageMagick (v. 6.2.4 at the time of writing this post), that can be installed as easy as

You've spent hours installing, configuring, and tweaking your system into perfection. Every device is working properly, every patch applied, every last last application is up to date, and your system is contently purring like a lion with a belly full of wildebeest. This is a prime time to save an image of your system in case anything screws it up. There are many commercial solutions available, but what free utilities will properly back up your system?

Fedora: Fedora + Plasma + Unity, Design Interns, and New ISO Build

  • Fedora + Plasma + Unity = Nice looks?
    Hybrid things aren't usually the best option around. Like hybrid cars, for example. Technically, when you marry concepts, you change the energy state, and while this could make sense in that you blend the best of several worlds, when this is done in a forced manner over a short period of time rather than eons of evolution, you end with the worst bits as the product of your mutation. I read about the United theme for Plasma a few months ago, and given that I've spent a fair deal of time fiddling with themes and icons and fonts and making different desktop environments look prettier than their defaults, I was intrigued. So I decided to see whether the notion of having Plasma look like Unity is a sane option. Let us.  Fedora + Plasma + Unity = Nice looks? [...] What is thy point, Vanessa, the astute among you may ask? Well, I have nothing against United or its creators, but I did come to the conclusion that too much tweaking is worse than no tweaking, if this statement makes sense. I like the notion of trying to overcome the inherent problems in each desktop through the use of themes and extensions. After all, I've been doing that profusely for the past few months. But it gets undone when you cross the desktop environment space. Making Gnome better yes. Making Plasma better, absolutely. Unity as an overlay for Plasma, well tricky. There's too much disparity for you to be able to hide the underlying workflow mechanisms and UI philosophies. Then, every little inconsistency glares. You notice things you do not expect, and you get angry because there are certain things you do expect. Some transformations work quite well because they build on the foundations, e.g. various Gnome panels or Macbuntu. But Plasma has its own special charm and flow and making it into a weird version of Unity, which itself is a weird version of Gnome misses the bigger picture. And so, if you're asking me, Plasma and Unity are two separate worlds, best enjoyed in isolation. United is an interesting notion, but it also signifies the upper limit for my own wild ideas and tweaking. Yes, you can make it work, then again, it means taking away from the beauty and style of what these two desktops do, and that's not the purpose of my pimping guides. So we shall stop here, and explore other colors and shapes. Have fun, little penguins.
  • Fedora Design Interns 2017
    Here’s an update on internships. Older post linked to here. Quick recap: there’s been 2 long-term interns for Fedora design team since February, and one short-term guy, who came for 2 weeks at the beginning of June. Guys have been doing an amazing job, I can’t stress enough how happy I am to have them around.

Security: Hardware Back Doors, Microsoft Windows, Kronos

  • Hiding malware in boobytrapped replacement screens would undetectably compromise your mobile device
     

    On the one hand, if you let an untrusted stranger install hardware in your electronic device, you're opening yourself up to all kinds of potential mischief; on the other hand, an estimated one in five smartphones has a cracked screen and the easiest, most efficient and cheapest way to get that fixed is to go to your corner repair-shop.  

  • How hackers {sic} are targeting the shipping industry [iophk: "Microsoft TCO"]
     

    Whenever one of the firm's fuel suppliers would send an email asking for payment, the virus simply changed the text of the message before it was read, adding a different bank account number.  

  • Locky ransomware is back from the dead with two new strains [iophk: "Windows TCO"]
     

    What hasn't changed, though, is the method of distribution.Rather than rifling through the trove of spilt US National Security Agency exploits, as the groups behind WannaCry and NotPetya did, Locky is distributed via phishing emails containing malicious Microsoft Office files or zipped attachments containing a malicious script.

  • Connected cars could have an airbag problem
     

    "It's not the car manufacturers' fault, and it's not a problem introduced by them. The security issue that we leveraged in our research lies in the standard that specifies how the car device network (i.e., CAN) works," added Trend.

    [...] To eliminate the risk entirely, an updated CAN standard should be proposed, adopted, and implemented. This whole process would likely require another generation of vehicles."

  • Code chunk in Kronos malware used long before MalwareTech published it
    A chunk of code found in the Kronos bank-fraud malware originated more than six years before security researcher Marcus Hutchins is accused of developing the underlying code, a fellow security researcher said Friday. The conclusion, reached in an analysis of Kronos published by security firm Malwarebytes, by no means proves or disproves federal prosecutors' allegations that Hutchins wrote Kronos code and played a role in the sale of the malware. It does, however, clarify speculation over a Tweet from January 2015, in which MalwareTech—the online handle Hutchins used—complained that a complex piece of code he had published a month earlier had been added to an unnamed malware sample without his permission.
  • Secret chips in replacement parts can completely hijack your phone’s security
    People with cracked touch screens or similar smartphone maladies have a new headache to consider: the possibility the replacement parts installed by repair shops contain secret hardware that completely hijacks the security of the device. The concern arises from research that shows how replacement screens—one put into a Huawei Nexus 6P and the other into an LG G Pad 7.0—can be used to surreptitiously log keyboard input and patterns, install malicious apps, and take pictures and e-mail them to the attacker. The booby-trapped screens also exploited operating system vulnerabilities that bypassed key security protections built into the phones. The malicious parts cost less than $10 and could easily be mass-produced. Most chilling of all, to most people, the booby-trapped parts could be indistinguishable from legitimate ones, a trait that could leave many service technicians unaware of the maliciousness. There would be no sign of tampering unless someone with a background in hardware disassembled the repaired phone and inspected it.

Ubuntu: Themes and Icons, MAAS, Podcast and More

  • Some interesting Ubuntu themes and icons
    Well, I guess there isn't much to say. If you like the stock looks, ignore this article. If you find the defaults not colorful or fun enough, or you just plain like tweaking, then you might want to consider some of the stuff I've outlined here. My taste is subjective, of course, but then, I aim for simple, clean designs and pleasing art work. Overall, you have a plenty of good options here. More icons than themes. Vimix or Arc seem like neat choices for the latter, and among the sea of icons, Moka, Numix and Uniform seem to do a great job. And of course, Macbuntu. I wish there were more monochrome or accented icons, but that's something I still haven't found. Anyhow, I hope you like this silly little piece. If you have suggestions, please send them, just remember my aesthetics criteria - simplicity of installation, clean lines, no gradients, no bugs. That would be all for today, fellas.
