Comment Re: Truly easy to exploit (Score 1) 109

For some reason ubuntu installed 4.4.0-45 but insisted on still booting So after a full upgrade and a reboot it was still vulnerable. After I I discovered the problem and booted 4.4.0-45 I confirmed that fixed the problem.

Raspbian seems not to be fixed (please correct me if I am wrong).

Comment Truly easy to exploit (Score 4, Informative) 109

I found one of these "exploits in the wild":

It works on the three Linux machines I first tested it on.
$ dirtyc0w /etc/secretfile.txt abcde
simply (over)writes abcde to the beginning of the file.

Fix seems to be available for none of the systems right now.

At least it requires a local account.... I mean, after all, it must be considered a security problem to allow web users to upload binaries or run arbitrary commands via a web server anyway. But if I was responsible for a students lab with hundreds of Linux computers I would be a little nervous.

Comment Or stay on LTS (Score 4, Interesting) 78

I have always upgraded Ubuntu to the latest version. But 16.04 is LTS and the rate of change is not very high (it was long since I needed to upgrade to get something I did not have access to in the earlier version). So I think about remaining on LTS, for the first time ever. Thoughts on that?

Comment Re:Because OS X is no longer supported on my Mac (Score 1) 592

I much agree!
My PowerBook G4@866MHz with 1GB RAM makes a perfect home server.
Apple did not support it in a very long time.
Right now I am typing on a MacBook2,1 from 2007 with Core 2 Duo CPU. It officially only supports Mac OS X 10.7, also not supported since long. I have managed to install OS X 10.9 Mavericks on it (using SFOTT, not really turning it into a Hackintosh, but half way). Very close to putting Xubuntu or Debian on it instead.

Those of you with a G4 MacMini - give it a try with Debian as a server.

About energy/electricity... producing new hardware use very much energy. And a RaspberryRi requires other stuff, and a hard disk. All of it requires energy to produce and run. I think my MacBook is at least twice as fast on most relevant tasks as a RaspberryPi (yes, I have those ones too, and I have made tests).

Comment Windows STILL way to big (Score 1) 554

Microsoft is putting pride in one-size-fits-all... that is, the same system on Smartphones, Tablets, Cheap Netbooks, Desktops, Workstations, Webservers and Datacenter servers. The different editions are not that different.

A Windows server does not get much lighter than 30-40 GB of disk drive and 1GB of RAM. For companies with virtual machines, 10s, 100s or 1000s of them, significant amount of resources are wasted here. There are of course SAN-technologies to de-duplicate blocks, but this is both advanced and expensive. Many Windows servers dont do more job (create more value) as a web-server, light database-server, printer server, or an AD/directory server than a RaspberryPi with Raspbian can easily do. Storage requirements for Raspian is 1-2% of Windows Server!

Tablet buyers who buy an iOS/Android tablet with 64GB of storage more or less gets 64GB for their media. While an owner of a 64GB Windows tablet finds that not much more than 32GB is actually available to be used.

Even if Microsoft manage to keep their requirements at the same level for the years to come, they will still be much heavier than the competition, and in many cases it matters.

But why not just write that: "We are no developers left on the project. If anyone seriously wants to take over we may hand over the source code under another license." Instead of making lots of effort creating a crippled version and lots of confusion?

Comment Re:Windows SDK, VS Express, etc (Score 1) 198

I agree about the separate download... I develop QT/C++ stuff sometimes. I develop in Linux, but I want to build executables for Mac and Win that I can distribute easily. There are different ways to do it, but last time I tried it, I got best result when I compiled QT myself, and then my Application against that QT build. (Perhaps at that time, it was the way to build pure 64-bit executable on Windows). So, yes, I just need the compiler, not the GUI.

But nevertheless it is good news that 64-bit tools come with Express.

Comment Windows SDK, VS Express, etc (Score 1) 198

I basically just want C/C++ libraries, compilers and build tools. But not the GUI of Visual Studio.

It used to be possible to Download the Windows SDK/Platform SDK for no charge, and it contained all the command line tools and libraries need to build applications. Now: directly from the download page: "The Windows SDK no longer ships with a complete command-line build environment. You must install a compiler and build environment separately. If you require a complete development environment that includes compilers and a build environment, you can download Visual Studio 2012 Express, which includes the appropriate components of the Windows SDK."

Years ago, Visual Studio C++ Express was 32-bit only, and the Window SDK made more sense for me.

Anyone knows if Visual Studio Express 2013 for Windows Desktop now comes with the 64-bit compiler too? In that case I can forget about the Windows SDK for now. Otherwise I will need to rely on old Windows SDK that came with the compiler. Or install professional version of Visual Studio of course.

Comment Re:Pictures that describe pornography are porn? (Score 1) 544

Problem is, it is NOT informative. Follow the links from picture searches above. Most of the pictures are just bad, pointless and vulgar. As people are quick to point out, it is arguably not even porn. I think anyone who really cares about the quality of Wikipedia and the creative commons stuff, should worry about these pictures as much as those people who are overly sensitive to nudity do.

Comment Re:nothing sensitive to latency (Score 1) 464

I agree! Mod up.

And, when it comes to databases... think about having a (few) large physical database server(s), and run your own "database hotel" that way.
My experience (mostly MS SQL) is that databases do not behave well in virtual environments. Better to consolidate by putting many databases on the same physical server, than putting many virtual database servers on the same physical server.
