fight corona with folding@home on a headless ubuntu linux box

Leave a reply

I wrote about using Grid computing to fight cancer a while back using leftover Azure credits.
So now with Corona having the world in its grip, it’s time to shift our attention to that nasty virus and throw some CPU cycles at it instead.

If you have an Ubuntu machine running somewhere and you want to install the Folding@Home client on it, you can do so by following the simple steps listed below.

First download the FAH client application:

wget https://download.foldingathome.org/releases/public/release/fahclient/debian-testing-64bit/v7.4/fahclient_7.4.4_amd64.deb

Then, run the installer. It will guide you through the setup process.

sudo dpkg -i --force-depends fahclient_7.4.4_amd64.deb

Just choose a name and an optional team. You best let it start automatically as well.

That’s basically it. Since you’re running it all headless, there’s no need for any of the other packages listed on the site.

You can check if things are running by checking the log file stored in /var/lib/fahclient/log.txt

If you want to change the configuration after installing the client in /etc/fahclient/config.xml you have to start and stop the client like this:

sudo /etc/init.d/FAHClient stop
sudo /etc/init.d/FAHClient start

If you had the World Grid Computing client installed already, you can stop that by using:

sudo /etc/init.d/boinc-client stop

If you want to full install instructions for the FAHclient or installation instructions for other flavors of Linux, check out the official installation guide.
Once it’s running and processed a few work units, you can check your stats at this URL: https://stats.foldingathome.org/donor/yourname

Have fun kicking Corona ass!

stop the EU from destroying your internet freedom

2 Replies

The EU Parliament will debate and vote on Article 13 & 11. Time to fire up your email and social media devices and let yourself be heard again, which is why I’m resurfacing this post about the what and the why.
The fight is still not over so sign the petition and let yourself be heard.

Yep. They are at it again, those pesky governments. If it ain’t the US trying to destroy net neutrality it’s the EU trying to setup a link tax and an automated content filter/surveillance/censorship machine.

I’m talking about the copyright reform law the EU is trying to get through in a few days.

Article 11 is bad. It tries to setup a link tax, meaning you cant link or post snippets to e.g. news articles on your site. A similar law was passed earlier in Spain and it causes Google news to simply pull back out of Spain. If the same happens to the whole of the EU, that would suck mayor balls.

Article 13 is far worse though. That’s the content filter, which means any site where content can be uploaded e.g. Facebook, Twitter, Instagram, Imgur etc will be forced to automatically scan your upload and filter it if it isn’t allowed. The claim is that they want to stop terrorists and bad people from spreading illegal content on the internet. The reality will be that those bad guys will find ways around it and the rest of us will be stuck with a filter that’s going to block our uploads because of flawed algorithms and bureaucratic decisions. Internet memes use copyrighted content, but will the filter be able to detect sarcasm? I don’t think so.

Hey look, a meme, with a copyrighted image. I guess we won't be able to do that anymore once Article 13 is in effect.

To quote Tim Berners Lee, the inventor of the WWW:

Article 13 takes an unprecedented step towards the transformation of the Internet, from an open platform for sharing and innovation, into a tool for the automated surveillance and control of its users.

So please help out and email, tweet or call your MEP’s and make it clear Article 11 & 13 have to go. The freedom of the internet depends on you!

join the EFF summer security reboot and get some cool dice

DSC01217The Electronic Frontier Foundation is on the fore-front when it comes to defending our digital rights. Even as a European I think they are doing important work even though they are mostly US centric. This because whatever happens in the US ripples over the pond and affects Europe and the rest of the world anyway. That means that next to larger fast-food portions increased digital surveillance is on its way to the EU as well.
Next to protecting our digital rights they are the author of a number of awesome security plugins and tools like the HTTPS Everywhere and Privacy Badger browser plugins and a driving force behind the Let’s Encrypt free web site certificate tool set.

Next to a lot of security tools and tips (see the site & newsletter) they now have a Summer Security Reboot fund drive where you can get a cool geeky secure-password generating dice set for a mere $20 membership until the 20th of July.

So if you like what they are doing for a secure and free internet in the future, go check them out and get yourself some cool dice in the process.

If you feel more like donating to a EU centric counterpart of EFF, you can check out EDRI.org instead (no dice there though).

reset the net

On´n´Off - Going into standby mode

It’s on!

If you want to kick some NSA buttocks and claim your privacy then get yourself this reset the net pack and install some super-duper encryption for your PC, Mac and phone(s).

There ain’t that much on there really, but if you scroll down to the Other Resources section there’s links there like the Prism Break one I mentioned before, which contain tons of (more techy) tools and software for all your stealthy encryption needs.

don’t let the EU censor your internet: stop ACTA

Leave a reply

You might have heard that SOPA got stopped (for now) in the USA, a bill to censor the internet and limit online freedom for everyone. An even worse deal is going down on our EU-side of the globe unfortunately, where ACTA (Anti-Counterfeiting Trade Agreement) has already been signed, but not yet approved (luckily).

ACTA – a global treaty – could allow corporations to censor the Internet. Negotiated in secret by a small number of rich countries and corporate powers, it would set up a shadowy new anti-counterfeiting body to allow private interests to police everything that we do online and impose massive penalties — even prison sentences — against people they say have harmed their business.
– avaaz.org

So it’s about time to do something about this before this bill gets voted in the EU Parliament and gets adopted globally.
First you can start by reading about ACTA, find out what’s wrong with it, sign the petition and act against it.

For those in the US, you can go sign the White House petition. Do it, because this deal is worse than SOPA, as it spans beyond the internet and deals even with regulations on medication and food.

The oppressively strict regulations could mean people everywhere are punished for simple acts such as sharing a newspaper article or uploading a video of a party where copyrighted music is played. Sold as a trade agreement to protect copyrights, ACTA could also ban lifesaving generic drugs and threaten local farmers’ access to the seeds they need. And, amazingly, t he ACTA committee will have carte blanche to change its own rules and sanctions with no democratic scrutiny.

Spread the word, sign the petition, just do something so this is stopped just like SOPA was.

Afterwards, you can get back to your memes and lolcats. :)

break out of the search bubble

This is relevant to my interests

Did you know that when you search on the popular search engines these days you’re actually doing that from inside a “search bubble”? Google, Bing and Yahoo all do it, to give you more tailored and “relevant to your interest” results.

Let’s take Google for example, since most people are using that one anyway. They are tracking your searches and clicks, if you’re logged in or not. They do this to compose a profile on you so that they can give you more specific search results the next time you look for something. They try to determine your sex, age and location (just like on IRC) to feed you the search results your are probably looking for. They are filtering the information based on a profile they’ve created on you.

The damn thing is that this actually works quite well. As a software developer I search a lot for technical, programming related topics. Google knows this and will give me those before any other possible hits. But what are you missing? What links are not included in your personal bubble just because Mr Google finds them irrelevant for you?

So how do you bust out of this bubble? You could use a browser with privacy mode but as long as you’re still using Google to search, or Chrome, you can’t be sure.

Another way is to use a different search engine. I know! A different search engine. It’s been ages since that happened right?

Enter DuckDuckGo. Beside the funny name and the mascot (A duck! Who would have guessed!) this one doesn’t put you in a bubble, doesn’t track your info and uses SSL by default.
Give it a try, and you’ll see that your results are quite different from Google’s. I have to be honest here and say that in some cases, the Google results are “better”. But that’s the bubble at work here.

DuckDuckGo also has a ton of specific search goodies like a built-in calculator and conversion engine, some specific tech goodies (whois queries, md5 hashes etc) and the !bang searches which allow you to search sites and topics directly.

As you can see, there’s plenty of reasons to try this new duck on the block out and burst out of your search bubble. The goodies alone make it worth checking out imo.
