Linux Controls a Gasoline Engine With Machine Learning

ls671 Re:I didn't see any mention of efficiency. (89 comments)

Here the goal is to make the engine spend as much fuel as possible, hence the term "chaotic combustion". The system can maintain the engine in a "chaotic combustion" state in real time ;-)

Why We're Not Going To See Sub-orbital Airliners

ls671 Re:huh? (300 comments)

I don't think he is. The Concorde had a weakness that was discovered only in one of the last flight.

Why We're Not Going To See Sub-orbital Airliners

ls671 Re:fail (300 comments)

Right, just attach the suborbital planes in pair with a rope to some space elevator like device and have one take off as the other land. Problem solved.

Bots Scanning GitHub To Steal Amazon EC2 Keys

ls671 Re:Summary without technobabble (119 comments)

>Thirdly, "bought" 30 million certs?

Oh and yes, that's why we were both laughing our hearts out and calling shenanigan at the same time. As I wrote in my OP, I would have been glad to generate those certs for them for 10,000$ instead of the 30,000,000$ they spent. But hey, a buck a piece for certs is a great deal, isn't it?

The usb key solution was suggested as well but the conclusion was that dumb users would lose their usb keys and that it would become too costly to manage.

In the end, we seem to be doomed unless we educate people.

Bots Scanning GitHub To Steal Amazon EC2 Keys

ls671 Re:Summary without technobabble (119 comments)

I agree it is currently. It is funny although what a little education could do but most of the times, educated people are less easy to profit from. Therefore, marketing guys will rarely suggest educating people as a solution.

Bots Scanning GitHub To Steal Amazon EC2 Keys

ls671 Re:Summary without technobabble (119 comments)

I entirely agree but for some, namely the ones who still use symmetric keys, this has become an old school thought.

In Canada, the government bought 30 millions certificates for all its citizens in oder to authenticate for government on line services for a buck a piece. Total: 30,000,000$

I would have been glad to provide it to them for 10,000$ and guess what? All privaye keys were kept centrally ;-) Us, old school guys just couldn't believe it.

The big thinkers/marketing guys decided that it was just to complicated for citizens to manage and keep their secret key in a secure location.

Interesting review on global warming

ls671 ls671 writes  |  about 5 years ago

ls671 (1122017) writes "I am currently listening to an interesting video presentation on global warming by Warren Meyer. You can get the torrent from Mininova at:

http://www.mininova.org/search/?search=Catastrophe+Denied&cat=0

Please note that Mininova only offers legit torrents since a while now, so no piracy involved in downloading it ;-)

Although the guy would be categorized as a "skeptic", he doesn't deny the temperature is rising so he doesn't sound to "extreme" in presenting his point; he seems to be mostly reviewing the evidence provided by what he calls the "climate alarmists". He seems to be doing a pretty good job at it and he seems to be using a rather scientific approach.

Anyway, have a look at it if you are interested on this topic. Also, this seems to be fresh (late 2009, early 2010) ;-)"

ls671 ls671 writes  |  more than 5 years ago

ls671 (1122017) writes "FORT COLLINS, Colo. — A 6-year-old boy is floating over northeastern Colorado in a homebuilt balloon and authorities are racing to try and rescue him.

The balloon, in the shape of a flying saucer is covered in foil and filled with helium. It has a compartment for a passenger underneath. It lifted the boy into the air near Fort Collins Thursday morning after the balloon became untethered at the boy's home.

EtherApe to monitor your network traffic

ls671 ls671 writes  |  more than 7 years ago

ls671 (1122017) writes "I like to monitor our systems with tail -f on the various log files and going back into them if needed to understand what happened but this tool is just too cool. I now keep it running on my desktop reserved exclusively to the tail -f of the log files side by side with the xterms. Read More Here"

Stratum 1 ntp server myth

ls671 ls671 writes  |  more than 7 years ago

ls671 (1122017) writes "There is a myth that prevails in the ntp community; it is better to connect to low stratum (e.g. stratum 1) servers in order to get more precise time. This is false quite often. It is explained here along with examples of poorly configured ntp servers."

Linus on debugger

ls671 ls671 writes  |  more than 7 years ago

ls671 (1122017) writes "A few months ago, I wrote in Slashdot that I do not use debuggers, except to reverse engineer code. CryBaby then started to pick on me telling me I was stupid and too lazy to learn how to use one. I felt all alone in the world since I do not know many people that share my views on this subject ;-) I searched for opinions and I was glad to find that Linus shares my views. Is there only Linus, 3 other guys that I know and myself thinking this way or there are more people agreeing in the /. crowd ? Read details here"

Apache reverse-proxy to secure your infrastructure

ls671 ls671 writes  |  more than 7 years ago

ls671 (1122017) writes "This article explains how to set up a secure and efficient environment. Logically, it is comparable to the setups used in large corporations like banks, governments, military, insurance companies etc. We will do this using a single computer with 4GB RAM, apache mod_proxy in reverse proxy mode and the freely available vmware-server.

Fooling around with deep cycle batteries and UPS?

ls671 ls671 writes  |  more than 7 years ago

ls671 writes "I have been experimenting with deep cycles batteries connected directly to APC UPSes for a while and I have grown tired of fooling around with battery chargers (since UPSes can't handle recharging a deep cycle battery). I was looking at a cost of approximately 5000$ to implement a robust solution and I finally came up with a solution that only required to invest 1000$ more than I had already done. You can view the results here."
