Slashdot Asks: What's In Your Home Datacenter?

ls671 Re:Learning Lab (253 comments)

Maybe, I don't see the use for u-racks anymore for a home data centers. I just use a desktop with four screens attached to it and one server with 64GB RAM acting as file server/firewall/router and running a bunch of virtual machines with qemu. XVNC or RDP for VMs running a graphical interface, ssh for others. I also have a UPS to keep everything alive for 6 hours if power goes out, about 20 hours if I shut the desktop down and use a laptop instead.

Mystery Signal Could Be Dark Matter Hint In ISS Detector

ls671 Re:Huh? (53 comments)

Interesting, the "shadow of the hype" is still hype. You seem to be underestimating me.

Apart from that, you are basically saying the same thing as I do and rest assured I have been following your recommendations for quite a while, especially the part about: "you could be making decisions for yourself based on the actual arguments and data involved."

Please watch the TV Show Manhattan.

Yet, back then, at some stage, almost the whole scientific community was hyped on ThinMan which ended up being trashed. Implosion prevailed.

All I am saying is don't jump to conclusions and follow the scientific community hype too easily.

Mystery Signal Could Be Dark Matter Hint In ISS Detector

ls671 Re:Huh? (53 comments)

I never mentioned large black holes and I was using the quote to demonstrate that we still do not know what is going on really yet.

Anyway, this seems recent enough ( April 30, 2014):
"Black hole atoms now join a long list of candidates for dark matter particles, from supersymmetric neutralinos, WIMPs and axions to warm sterile neutrinos and many more, Dokuchaev told Space.com. Verifying whether any of them is the real deal will require catching one first, he added."

Mystery Signal Could Be Dark Matter Hint In ISS Detector

ls671 Re:Huh? (53 comments)

Do you need anti-matter for "annihilating the Milky Way's halo"?

Dark matter could be made of black holes:

"There have been many candidates for this theorized "dark" matter, and in truth it is probably some combination of them: hot or cold gas, neutron stars, white or brown dwarfs, exotic particles and, yes, even black holes!"

Ask Slashdot: Remote Support For Disconnected, Computer-Illiterate Relatives

ls671 Re:Dial up can still access gmail (329 comments)

Some stupid student had pictures of himself naked with his gay friend in his University home folder! ;-)

Some normal student with a sexlife had private pictures in his private University home directory.

There is a difference between common sense and privacy. University conditions specifically forbid private use anyways. It has to be for University related activities, like conducting research on security vulnerabilities for instance ;-))

although I was tempted to post the gay guys pictures somewhere public.

Why would you do that? What exactly tempted you?

Puberty, stereotypes, society ??? Important thing is I didn't.

Ask Slashdot: Remote Support For Disconnected, Computer-Illiterate Relatives

ls671 Re:Dial up can still access gmail (329 comments)

This isn't practical when you don't have a dedicated phone line for it and even then many ISPs had systems set up to not allow you to keep connections on constantly like that.

Also, I remember signing up with a big telco where I live that advertised unlimited access. I phoned them and told them up front that I was going to be on 24/24 and they said; no problems, so I signed.

I quickly discovered that they would hang up after 6 hours. We had to dial-in again and they seemed to purposely change the IP address everytime, anyway, I never got the same IP twice in a row.

God what fun I had using dyndns short DNS records TTL and all kinds of "adjustments" to have something relatively stable. User knew the network would go down for 10 minutes everyday during a business day and they got used it.

OK, I have to stop. I am laughing my heart out.

Ask Slashdot: Remote Support For Disconnected, Computer-Illiterate Relatives

ls671 Re:Dial up can still access gmail (329 comments)

Thanks, I see what you mean. It is pretty much like typical cable/dsl modems look nowadays.

I don't recall encountering those although I would replicate the functionality by connecting the modem with a serial cable to a linux router. I pretty much always used a linux router from the start. Even nowadays, I always have the "ethernet" cable/dsl whatever modem in pass-trough mode to the Linux router through an RJ45 connector.

I remember setting rules on linux routers for the following use case you described, those were on coaxial ethernet :-)
" because once a computer thinks it has an always-on network connection it tends to try making remote connections for all sorts of things unless you lock it down. So the modem was always connected pretty much. This isn't practical when you don't have a dedicated phone line for it and even then many ISPs had systems set up to not allow you to keep connections on constantly like that"

It could, with an ethernet dial-up modem.

Sorry to ask, what the heck is an ethernet dial-up modem??

ISDN? Does ppp over a voice line modem qualifies also? pppoe + dsl ??

I am puzzled...

ls671 Re:Dial up can still access gmail (329 comments)

Haha, I have never been so nasty but I fooled around a little I have to admit.

In IT classes, we had like 20-30 work stations running SunOS with X. I would set my display to another student station,
DISPLAY=other_student_ip ; export DISPLAY
wait until the teacher comes to his station then launch netscape with a porn site target URL. I had good laughs back then. Student would usually try to close the netscape windows while the teacher would give him a suspicious look maybe thinking it was already open and minimized and that the student had just maximized the window by mistake. I could have got caught easily I assume if he left it running and instead investigated where that window was coming but I didn't risk much getting caught.

Also, X allowed you to get the keys typed on any station and steal login credentials then access other student accounts.

Some stupid student had pictures of himself naked with his gay friend in his University home folder! ;-)

Back then the laws weren't very clear about such activities as long as you didn't tamper the data, steal it for your own use, use it to blackmail somebody, try to get money or other advantages from it, etc. so I stayed on the safe side and only looked around although I was tempted to post the gay guys pictures somewhere public. Like today, I must have already been some kind of a white hat since I didn't and didn't mention it to anybody either.

Navy Guilty of Illegally Broad Online Searches: Child Porn Conviction Overturned

ls671 Re: Problem? (286 comments)

it is so important that the "good guys" don't break the law to catch the "bad guys". Ever.

Then, you might have to shut down several deep cover operations. Breaking the law by doing mass surveillance is a different topic although.

Google Receives Takedown Request Every 8 Milliseconds

"5 minutes it takes sending the request"

More likely, they have automated the whole process and it takes them milliseconds to send the request to several parties.

Dear Satya,

I thought you were a girl based on your name. So I went to the interwebs to find a picture of yourself to see if you were cute.

Oh well, maybe I will have better luck next time.

Interesting review on global warming

ls671 ls671 writes  |  more than 4 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 (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.

Stratum 1 ntp server myth

Linus on debugger

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

Fooling around with deep cycle batteries and UPS?

ls671 ls671 writes  |  about 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."
