Why Women Have No Time For Wikipedia

emj Re:perhaps men and women are different? (501 comments)

Perhaps you could expand on how Facebook emulates what you see in the yard with girls? It really has never occurred to me. Please remember that your own experience is a very small sample, and your opinions will rule over your experiences (some kind of personal conditioning, the exact term in english alludes me atm).

A Bike Taillight that Goes Beyond Mere Taillighting (Video)

emj Re:Great job David! (86 comments)

I do expect my investment in an onboard camera to pay off, unfortunately, when one of these bumbling fools gets too darn close for comfort. Sorry, but stupidity should pay a price in real life. Why should I get stuck with the bill because I drive carefully and you do not?

Well you are driving around in a massively dangerous thing that destroys the lives of so many people, that's why you should pay when you hit a person. Because when cars are driven too fast, anything above 30 km/h, they kill people.

Comcast Predicts Usage Cap Within 5 Years

emj Re:2 kinds of countries in the world (475 comments)

Regulation is only part of the problem, I've heard complaints about the US being too conservative against new broadband tech. One of the reasons why you are getting usable broadband now and not 15 years ago.

Comcast Predicts Usage Cap Within 5 Years

emj Those can not be real costs (475 comments)

Here in Sweden we pay up to $8000 for a fiber connection to a house, there are lots of appartments that get it a lot cheaper though (for free).

Microsoft Cheaper To Use Than Open Source Software, UK CIO Says

emj Re:Familiarity (589 comments)

I've never understood what exchange+óutlook actually gives you, please enlighten me. I supported a couple of houndred people using exchange in grad school, the most complicated question I got was how to make your address book sync properly. It might be all those extension that people write for Exchange, which sync to strange places.

Volvo Testing Autonomous Cars On Public Roads

emj Re:No way I could trust a self-driving car (98 comments)

Once self-driving cars hit the road in any numbers, it will become really, really expensive to try to be a jerk in traffic. No speeding. No lane cutting. No tailgating. No weaving. No nothing - just follow the traffic flow and the law to the letter and spirit or you will get reported. And of course your insurance rate will like go up, simply by being a human driver.

It's not clear that they will be allowed to record all that, at least not in Sweden, which this story is about. Privacy problems and all that.

Unreal Engine 4 Launching With Full Source Code

In the old times, FPS was not about multiplayer. I stopped playing them around the time it became like that.

That would be around 1996 when Quake was released.

Which is why in civilised countries we have unions and employment law.

I was a bit sad when I read that she had to request HR to be present at a meeting with the boss, you need a union on your side when you have those conversations.

How Do You Backup 20TB of Data?

emj Re:If you want to hoard bits... (983 comments)

If I were doing this with drives, I'd grab an 8x SATA card, 8 4TB drives, an external hot-swap shelf, and setup RAIDZ-2 with compression on it. .... Cost is about $1800. That's totally a backup. A second set of backups is another $1300.

Can somebody compare the cost for tape?

You pay about ~$1800-$2500 for tapes, a tape driver, and SAS card, depending on vendor, an extra 27 tapes to store 20TB again would be about $700. The big win is that the tape setup take less space, changing tapes every 800GB is not so hot though, but you get used to it. I've used 4 tape drives in parallel to be able to backup all data generated durng the day, it's ok, you learn to handle that with the morning coffee.

Electric Bikes Get More Elegant Every Year (Video)

emj Re:so its a moped? (164 comments)

You can not get a good bicycle that cheap, sure you can spend lots of time renovating old bicycles, but they probably did cost a lot more than $150 when new.

Electric Bikes Get More Elegant Every Year (Video)

emj Re:Not in my experience (164 comments)

Out of about 80 bikes that are locked outside my building, only 4-5 are racing bikes. If I was in the Netherlands, Germany or Denmark it would be more like 1 / 80.

Far less than that, normally people do not use racing bikes for everyday use. I stood in a busy bicycle intersection and saw ~200 upright bicycles not one racing bike.

Electric Bikes Get More Elegant Every Year (Video)

emj Re:Still ugly (164 comments)

If you just ride an hour or two on the weekend, then a cushy seat and upright posture feels comfortable. If you ride many more hours per week it's a prescription for saddle sores

I've biked 300km during three days in upright position, it's easy and I had not problem. Further, there are thousands of people doing at least 100 km a week in upright position over here.

Booting Linux in five seconds on EeePC

emj emj writes  |  more than 5 years ago

emj (15659) writes "At the Linux Plumbers Conference Arjan van de Ven, Linux from Intel demonstrated a Linux system booting in five seconds. The hardware was an Asus EEE PC, which has solid-state storage, and the two developers beat the five second mark. They had to hold up the EEE PC for the audience, since the time required to finish booting was less than the time needed for the projector to sync. "Done booting means CPU and disk idle," Arjan said, but it did not include bringing up the network completly."

Open Source GSM base station software

emj emj writes  |  more than 5 years ago

emj (15659) writes "Software defined radio has really come a long way, here's a summary about the OpenBTS software that lets you run a GSM base station with GNU radio. All software isn't available yet, but the OpenBTS people made a field test at Burningman in August and have a nice page describing the tech they brought with them. If that's not enough, the hardware they used can be used with GPS receiver software as well."

Screen with 180 degress field of view

emj emj writes  |  more than 6 years ago

emj writes "Who wouldn't want to be immersed in a 3D world, a gamer has actually has invented just this, jDome a 180 degree FOV screen. All you need is a semi-transparent back projected dome, and setting the in game field of view to 180. At a preorder cost of just $200, it is a lot of immersion per dollar, considering that a full VR-cube will cost you a million bucks. Watch the high res video of jDome or settle for the YouTube version on the home page."

Laptop memory upgrade without getting heat

emj emj writes  |  more than 6 years ago

emj writes "Is it possible to upgrade the memory of an old laptop without getting a big heat output from the new memory modules? I recently added an old 256MB module to my laptop, but this increased the heat output and is making the fan run non stop. What should you look for in memory chips when you want low heat, low power and lots of RAM? (heat sinking is not an option)"

Drag and Drop upload on webpages

emj (15659) writes "Now there is an extension for Firefox that can upload files by using drag and drop, some sites e.g. Gmail you can now drop several files and they will directly be added to the upload form. The question is when this will become standard in all browsers considering the amount of people doing this the first time they try to attach a file."

Mounting filesystems with out root

emj emj writes  |  more than 6 years ago

emj (15659) writes "An LWN article talks aboutpatch by Miklos Szeredi enables an unprivileged user process to call the mount() system call and and have that call actually succeed. The setuid mount utility is no longer needed, giving users more flexibility in setting up their environments. One might well wonder why this change to mount() is called for, given that users have been able to do unprivileged mounts for years, but this lets people mount without editing fstab,"

I really can't stand these audio based ads that Slashdot has started running, I have no problem with advertisement I think it actually adds to the experience, lots of stuff that I use I've found via ads. So please slashdot stop running these Microsoft server 2012 or what ever, or at least make them pay more, I mean I do notice them more when they start playing in some background slashdot tab.

My URL is my content

emj emj writes  |  more than 5 years ago

A great inebriate hacker once told me "I schould build a content provider service, where the content is in the URL"... It took me about two years to understand what he ment, I think he ment that you can store data in "the cloud" or in the ether between the tubes. So I give openssl and some perl to make it look better:

echo "oh man where is this stored really? The intertubes?" |openssl base64 | perl -pne 'BEGIN{print "data:text/plain;base64,"} chop; END {print "\n"}'

Result:

data:text/plain;base64,b2ggbWFuIHdoZXJlIGlzIHRoaXMgc3RvcmVkIHJlYWxseT8gVGhlIGludGVydHViZXM/Cg==

Making sha1 hashes for backup and integrity checking..

emj emj writes  |  more than 5 years ago This will link one hash to one file, so if two files have the same hash the latter will overwrite the formers name. Thanks to Perl oneliners and lost+found recovery for inspiration.

xargs -0 openssl sha1 |
perl -ne '
sub parsesha1{
$sha1=substr($_,-41,40);
