Open Source is No Joke

The short version: Most Open Source Customer Relationship Management (CRM) applications are not fully functioning CRMs because they usually lack Reporting and Workflow. CRMs without these two features are useless. We want people to get value out of Zurmo. So we’re adding functionality that is usually available only in paid, Enterprise editions. Why? The current model teases people and insults our intelligence. We want people to take Zurmo and make it better. We want there to be a tool out there that’s easy to work with and to develop. By building software so a lot of people will use it, we’ll benefit by supporting it. That’s why we’re including all these features like Reporting and Workflow for free.

The long version: If you’re looking for a joke, watch a Jim Carry movie. Dumb and Dumber fits the bill. If you are looking for Open Source Customer Relationship Management (CRM) that’s along the same lines of ineptitude, just do a Google search. You have a bunch to pick from. Call them “teasers”. Call them bait and switch. Call them whatever you’d like. Just surely don’t call them full functioning CRM systems. I am serious. And please don’t call me Shirley.

Flux

Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen? During the day, computer screens look good—they’re designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn’t be looking at the sun.

f.lux fixes this: it makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day. It’s even possible that you’re staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

Hotfix Your Ubuntu Kernels with the Canonical Livepatch Service!

Today, Canonical has publicly launched the Canonical Livepatch Service — an authenticated, encrypted, signed stream of Linux livepatches that apply to the 64-bit Intel/AMD architecture of the Ubuntu 16.04 LTS (Xenial) Linux 4.4 kernel, addressing the highest and most critical security vulnerabilities, without requiring a reboot in order to take effect. This is particularly amazing for Container hosts — Docker, LXD, etc. — as all of the containers share the same kernel, and thus all instances benefit.

Live kernel patching from Canonical now available for Ubuntu 16.04 LTS

“Most serious” Linux privilege-escalation bug ever is under active exploit

The vulnerability, a variety known as a race condition, was found in the way Linux memory handles a duplication technique called copy on write. Untrusted users can exploit it to gain highly privileged write-access rights to memory mappings that would normally be read-only_

Dirty COW — Critical Linux Kernel Flaw Being Exploited in the Wild

Why is the Flaw called Dirty COW?

The bug, marked as “High” priority, gets its name from the copy-on-write (COW) mechanism in the Linux kernel, which is so broken that any application or malicious program can tamper with read-only root-owned executable files and setuid executables.

“A race condition was found in the way the Linux kernel’s memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings,” reads the website dedicated to Dirty COW.

“An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.”

The Dirty COW vulnerability has been present in the Linux kernel since version 2.6.22 in 2007, and is also believed to be present in Android, which is powered by the Linux kernel.

There are proof of concept available here.

Impact

An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
This flaw allows an attacker with a local system account to modify on-disk binaries, bypassing the standard permission mechanisms that would prevent modification without an appropriate permission set.

How

The In The Wild exploit relied on writing to /proc/self/mem on one side of the race.
The In The Wild exploit relied on using ptrace.
The attack relies on racing the madvise(MADV_DONTNEED) system call while having the page of the executable mmapped in memory.

IOT Targeted in Recent DDOS attacks of DNS

DNS, the internet traffic management company hit by DDoS attacks Friday which affected more than 80 popular websites, says it believes that smart devices such as webcams and thermostats were infiltrated to carry out the attacks.

Scores of websites including PayPal, Reddit, Amazon, Spotify and Twitter were unavailable Friday as three separate distributed denial of service (DDoS) attacks disrupted the New Hampshire based server’s operations.

Subject: System 76 Same As Clevo?

Message: Hello Chris and Noah,

Would i be able to use the system 76 PPA on a generic Clevo laptop of the same model that the Oryx Pro is built upon. I have an opportunity to purchase one second hand from a Windows user, and I’m sure i could get everything working under Ubuntu 16.10 (except for crappy wireless) .

The model is NP8152-S

Thank you both,
Best regards,

Running Debian on a Graphing Calculator

Thx to: Mikerr89 and sorry to bluphenix316!

The newer TI-Nspire series of graphing calculators uses modern ARM devices. [Codinghobbit] managed to get Debian Linux running on a TI-Nspire calculator, and has written a guide explaining how it’s done.

The process uses Ndless, a jailbreak which allows code to run at a low level on the device. Ndless also includes a full SDK, emulator, and debugger for developing apps. In this case, Ndless is used to load the Linux kernel.

Announcing Snappy Ubuntu

Guest: Dustin Kirkland (@dustinkirkland)

A new, transactionally updated Ubuntu for the cloud.

Ubuntu Core is a new rendition of Ubuntu for the cloud with transactional updates. Ubuntu Core is a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users — that’s why we call them “snappy” applications.

Snappy apps and Ubuntu Core itself can be upgraded atomically and rolled back if needed — a bulletproof approach to systems management that is perfect for container deployments. It’s called “transactional” or “image-based” systems management, and we’re delighted to make it available on every Ubuntu certified cloud.

Mark Shuttleworth » Blog Archive » Announcing Ubuntu Core, with snappy transactional updates!

What if your cloud instances could be updated with the same certainty and precision as your mobile phone — with carrier grade assurance that an update applies perfectly or is not applied at all? What if your apps could be isolated from one another completely, so there’s no possibility that installing one app could break another, and stronger assurance that a compromise of one app won’t compromise the data from another? When we set out to build the Ubuntu Phone we took on the challenge of raising the bar for reliability and security in the mobile market. And today that same technology is coming to the cloud, in the form of a new “snappy” image called Ubuntu Core, which is in beta today on Azure and as a KVM image you can run on any Linux machine.

Yahoo Starts Prompting Chrome Users To “Upgrade” To Firefox

If you’re visiting any Yahoo property today, chances are you’ll see an “Upgrade to the new Firefox” link in the top-right corner of your browser window. The prompt also appears if you’re using Internet Explorer, Opera and even the new Yandex browser. However, the prompt is missing from Safari, which will surely prompt a new round of speculation about Apple’s rumored switch to Yahoo as its default search engine.
