Linux 3.15 Will Suspend & Resume Much Faster

Janek Kozicki Re:It doesn't work at all. (117 comments)

It simply doesn't resume. HIbernation always works. You can see it on videos:
The *.mov files are records from hibernation/suspend attempt. They have polish names, ignore that. You can see that it reboots again right at the end of resume, then boots into log-in screen

I think it is related to my hardware: dual Xeon E5-2687Wv2, 64 GB of RAM, motherboard SUPERMICRO MBD-X9DRI, GPU nvidia GTX 780 (only debian approved nonfree drivers, no blobs from

Linux 3.15 Will Suspend & Resume Much Faster

Janek Kozicki It doesn't work at all. (117 comments)

What's the point if suspend resume doesn't work at all?

Here's my SLEEP script, in which I am testing various kernels:


logger "========== touch forcefsck ==========="
# if resume failed, then I want fsck (SSD disks, so it's just few seconds)
touch /forcefsck
sleep 1

logger "hibernating"
# it says there to try hibernating using various different methods

### method: 1 kernel 3,13,0 - fail, (2/6 success rate)

### method: 2 kernel 3,13,0 - fail, (3/6 success rate)

### method: 3 kernel 3.13.0 - fail, (2/6 success rate)
#echo platform > /sys/power/disk
#echo disk > /sys/power/state

### method: 4 kernel 3.13.0 - (3/6 success rate)
### kernel 3.2.0 - 80% sukcesów 20% fail (over 80/100 success rate - currently in use)
### kernel 3.12-bpo - (0/1) success rate)
echo shutdown > /sys/power/disk
echo disk > /sys/power/state

sleep 5
logger "restart network"
## something screws networking after resume
/etc/init.d/networking restart
sleep 2

## also UPS connection is screwed (sometimes I need to disconnect and reconnect the USB cable)
sleep 5
/etc/init.d/nut-client stop
sleep 5
/etc/init.d/nut-server stop
sleep 5
/etc/init.d/nut-server start
sleep 5
/etc/init.d/nut-client start
sleep 5
# don't mess with clock /etc/init.d/ntp restart
logger "resume complete"

Besides, this is old news. Our new and better site beat slashdot: . The only working kernel was 2.6.29 with tuxonice

As much as I don't like javascript too, I like very much how supports the math rendering engine MathJax. And along with UTF-8 support I think that we need the ability to discuss difficult topics using math to describe them.

Omate standalone smartwarch adds 1GB RAM/8GB storage version

Janek Kozicki Janek Kozicki writes  |  1 year,9 days

Janek Kozicki (722688) writes "Previously discussed on slashdot Omate Smartwatch has already met its funding goal. This smartwatch works as a standalone phone (but can also be paired), it is water-resistant (up to 1m underwater) and runs android 4.2.2. If it meets 800kUSD funding goal it will have the flexy invisible keyboard in which the whole screen becomes the keyboard, invisibly. And the app gets full screen instead of having part of it blocked by the onscreen keyboard. All you need is to be used to blind typing on a regular keyboard. Just yesterday it became possible to order a 1GB RAM/8GB storage version (there's microSD slot too). If it meets a 900kUSD stretch goal it will have an extra battery (current 600 mAh battery gives 100h standby, and 240 minutes for talking)."

Ubuntu Edge now $695, thanks to major industry backing

Janek Kozicki Janek Kozicki writes  |  about a year ago

Janek Kozicki (722688) writes "With 14 days to go, it’s time for our biggest announcement yet. From now until the end of the campaign, we’re fixing the price of the Ubuntu Edge at $695! No limited quantities, no more price changes. You wanted a more affordable Edge, and now you’ve got it.

So of course we’re passing those savings on to you. There’s now a single unlimited $695 Ubuntu Edge perk, which comes with a year’s subscription to LastPass Premium and a place on the Founders page. At the end of the campaign, anyone who’s already pledged more than $695 for the phone will be offered a refund of the difference.

Yesterday we announced that Bloomberg LP has snapped up the first of the $80,000 Enterprise bundles, and we expect more businesses to follow suit. To make it even more appealing, we’ve raised the number of phones included in the bundle from 100 to 115.

Ubuntu edge was already mentioned on slashdot."

Dwarf galaxies orbiting M31 are not randomly distributed.

Janek Kozicki Janek Kozicki writes  |  about a year and a half ago

Janek Kozicki writes "It has been long thought that dwarf galaxies orbiting Andromeda galaxy (M31), or any other galaxy for that matter, are distributed more or less randomly around the host galaxy. It seemed so obvious in fact that nobody took time to check this assumption. Until a 15 year old student Neil Ibata working with his father at the astronomic observatory wanted to check this out of curiosity. It turned out that dwarf galaxies tend to be placed on a plane around M31. The finding has been published in nature. Local press (especially in France) is ecstatic that a finding by a 15yr old got published in Nature. However, there's another more important point: what other obvious things we didn't really bother to check?"

Most Unusual black hole in NGC 1277

Janek Kozicki Janek Kozicki writes  |  about 2 years ago

Janek Kozicki (722688) writes "The black hole in NGC 1277 has total mass equalling to 14% of total galaxy mass. For comparison our galaxy's black hole is about 0.0003% of total Milky Way's mass. The finding has been published in nature (if you have university's free pdf access) and in few other places too. Looks like models describing creation of black holes need some revision."

Elon Musk plans to colonize Mars

Janek Kozicki Janek Kozicki writes  |  about 2 years ago

Janek Kozicki writes "Elon Musk plans to send 80'000 people to Mars, charging $500'000 each, within two decades. The ambitious Mars settlement program would start with a pioneering group of fewer than 10 people, who would journey to the Red Planet aboard a huge reusable rocket powered by liquid oxygen and methane. "At Mars, you can start a self-sustaining civilization and grow it into something really big," Musk told an audience at the Royal Aeronautical Society in London on Nov. 16. Musk was there to talk about his business plans, and to receive the society’s gold medal for his contribution to the commercialization of space."

Wikipedia refuses to accept bitcoin donations

Janek Kozicki Janek Kozicki writes  |  about 2 years ago

Janek Kozicki writes "Wikipedia ran another donation campaign last week. One blogger offered them to donate in bitcoins. Wikipedia refused because currency has to be backed by government. Though wikipedia "may revisit this position should circumstances change'. Blogger mentions that wikipedia happily accepts money from Saudi Arabia where beheading and stoning women to death is institutionalized. A flame follows that if such a government backs bitcoins then wikipedia will start to accept it. Putting these issues aside, do you think that wikipedia should follow wordpress accepting bitcoins?

Matlab: Intel libs on AMD processor are 40% faster

Janek Kozicki (722688) writes "Stanislav Garmatiuk a digit-life editor encountered a fairly surprising result when performing MATLAB benchmarks of latest Phenom: it turns out that using Intel library (mkl.dll) gives about 40% performance boost when compared to AMD library (acml.dll) on AMD Phenom 9850. Also using three or four cores yields worse results than using just two cores. The test was performed using standard MATLAB benchmark suite, included in the package."

His invention is now complete with working air car prototypes, and serial production should start this summer. First they will be produced in France, then other factories will open in India and Spain. With single refuel (costing 1.5 EUR) the car can travel 200km at max. speed 110km/h. Depending on the model the car price will be between 3,500 EUR and 5,300 EUR. Some videos are available also."

Gasoline high-pressure engines may beat diesel

Janek Kozicki Janek Kozicki writes  |  about 7 years ago

Janek Kozicki writes "GM presented two cars with new engines that burn gasoline similarly as a diesel engine burns diesel fuel. The engines should get 15% better fuel economy than ordinary gasoline engines, but will not need the expensive exhaust treatment that diesel engines require. This type of engine technology known as Homogeneous Charge Compression Ignition (HCCI) promises the fuel economy of a diesel engine but with cleaner exhaust of a gasoline engine."

tiny surveillance system

Janek Kozicki Janek Kozicki writes  |  more than 9 years ago Today when going back home I took a shortcut through the forest near the city. And I was stalked by two men who wanted to rob me, but with some luck I escaped. Many people are going there to take a stroll because in overall it is a nice forest, so it is scary that it is so dangerous. I reported the incident, but I could only describe how bandits looked like. Police said that this certain place is a good spot for bandits, and that such incidents can happen there, even though they are patrolling this area quite often.

Since I'm not going to leave things like this, I have an idea to put some tiny surveillance system inside a bird house. I looked at tiny SBC systems. But nothing really appealed me. I'm looking for a very small linux stand-alone system, that will have just one USB connection to plugin a camera, and enough memory to store three days of video (preferably flash or RAM memory). Basically I want to monitor this area and capture possible incidents, in a similar manner to this one. To capture images I plan to use motion from sourceforge. I plan to visit the camera every few days and download data, but since this place in the forest is just 700m away from my flat, some real-time wireless data transmission would be nice too - if power consumption will not be to high.

Of course later, when I will capture bandits in action I'll post a followup story so that slashdot crowd can enjoy.
